Description

Method and device for resource scheduling

technical field

Embodiments of the present invention relate to the communication field, and more specifically, to a method and device for resource scheduling.

Background technique

The Internet of Things (IoT, Internet of Things) refers to the deployment of various devices with certain perception, calculation, execution and communication capabilities to obtain information in the physical world, and to realize information transmission, collaboration and processing through the network, so as to realize the realization of people and things. A network of interconnected things. Machine-to-machine communication (M2M, machine-to-machine Communication) is a technology and standardization concept proposed by the standardization organization 3GPP to study how to carry IoT applications on mobile communication networks. Currently, the enhancement or optimization of the mobile communication network required for the introduction of MTC (MTC, machine type communication) equipment is being studied. Among them, providing low-cost MTC terminals based on LTE (Long Term Evolution) is a research direction. The purpose is to provide LTE terminals whose cost can be compared with that of GSM/GPRS terminals, or even lower than the cost of GSM/GPRS terminals, to replace GSM/GPRS terminals used in M2M applications, so that LTE networks can be used in M2M applications to replace GSM /GPRS network.

It is known that there is a method to reduce the cost of the terminal by simplifying the HARQ (Hybrid Automatic Repeat Request) mechanism, which is to completely remove the HARQ mechanism, or reduce the maximum number of HARQ processes that the terminal can support, and reduce the number of HARQ processes Occupied storage space, to achieve the purpose of cost reduction.

However, completely removing the HARQ process mechanism will affect user experience. In terms of reducing the maximum number of HARQ processes supported by the terminal, in order to reduce complexity, for low-cost LTE MTC UE (hereinafter referred to as UE), the standard tends to define only one UE category (UE category) , to limit the modulation level supported by the UE, thereby determining the maximum transport block size (TB size, transport block size) supported by the UE and the available modulation and coding schemes. Then, if the maximum number of HARQ processes of the UE is uniformly limited, the maximum rate that all UEs can support will also be determined accordingly. However, due to the wide variety of M2M applications, the requirements for data rates are also inconsistent. For some applications, the above determined maximum data rate may not be necessary, which increases the energy consumption of the user equipment, and there is room for further reduction of cost and energy consumption.

At the same time, the reduction of the maximum number of supported HARQ processes makes it impossible to occupy all the downlink subframes for UE scheduling. For example, according to the existing protocol, downlink scheduling of 8 subframes is a cycle, and if the maximum number of HARQ processes supported by the downlink is 8, then the 8 downlink subframes have UE scheduling information. In addition, in order to maintain the flexibility of eNB scheduling, the resource position of eNB scheduling UE is not limited. In this way, even if the number of downlink HARQ processes actually used is less than 8, there is also an opportunity to schedule UE in all 8 downlink subframes. Therefore, the UE listens to the channel on all downlink subframes and receives scheduling information, which increases the energy of the user equipment for low-cost LTEMTC UEs with reduced latency and data rate requirements and increased energy consumption requirements. Consumption, there is room for further reductions in cost and energy consumption.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The technical solution of the embodiment of the present invention can be applied to a long term evolution (LTE, Long Term Evolution) system and the like.

A user (UE, User Equipment), also called a user equipment, a mobile terminal (Mobile Terminal), a mobile user equipment, etc., can communicate with one or more core networks via a radio access network (for example, RAN, Radio Access Network) For communication, the user equipment may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, such as a portable, pocket, hand-held, computer built-in or vehicle-mounted mobile device, They exchange language and/or data with the radio access network.

The base station may be an evolved base station (eNB or e-NodeB, E-UTRAN (Evolved Universal Terrestrial Radio Access Network) Node B) in LTE. The embodiment of the present invention is not limited, but for the convenience of description, the following embodiments use eNB Take this as an example.

The network side may be an Evolved Packet Core (EPC, Evolved Packet Core), which is not limited in the embodiments of the present invention, and the following embodiments are described using EPC as an example.

Fig. 1 shows a schematic flowchart of a resource scheduling method 100 according to an embodiment of the present invention, expressed from the perspective of an eNB. As shown in Figure 1, the method 100 includes:

S110. Determine resource scheduling information according to the target user, where the resource scheduling information includes maximum HARQ process number information used to indicate the maximum number of Hybrid Automatic Repeat Request HARQ processes that the target user can support and/or used to indicate subframes Whether it is possible to carry subframe information of the downlink control channel;

S120, perform resource scheduling on the target user according to the resource scheduling information.

Specifically, before performing resource scheduling on the target user, the eNB may first obtain the resource scheduling information of the target user from the UE or the EPC, or autonomously determine the subframe information included in the resource scheduling information and send it to the UE. Therefore, the eNB can Resource scheduling is performed on the UE according to the resource scheduling information, and the UE can accept resource scheduling from the eNB according to the resource scheduling information. In this embodiment of the present invention, the resource scheduling information may include information on the maximum number of HARQ processes used to indicate the maximum number of HARQ processes supported by the UE (hereinafter referred to as the maximum number of HARQ processes) and/or used to indicate whether the subframe may carry Subframe information of the downlink control channel. Since only one type of UE category (UE category) is defined for low-cost long-term evolution users (low-cost LTE MTC UE, hereinafter referred to as UE), the modulation level supported by the UE is limited, thereby determining the maximum transport block size supported by the UE ( TB size, transport block size) and available modulation and coding methods. Therefore, the maximum number of HARQ processes of the UE determines the maximum rate that the UE can support. In addition, according to the subframe information, the UE may monitor channels only on specified downlink subframes that may carry downlink control channels, and receive scheduling information. Therefore, the eNB can perform different scheduling according to the content included in the resource scheduling information (so that the number of HARQ processes allocated to the UE does not exceed the maximum number of HARQ processes indicated by the maximum number of HARQ processes information or bear the downlink control channel in the subframe information corresponding subframe). In the following, the case (1) in which the resource scheduling information includes the information on the maximum number of HARQ processes and the case (2) in which the resource scheduling information includes the subframe information will be described respectively.

Situation(1)

In the embodiment of the present invention, the UE may carry the resource scheduling information (for example, information about the maximum number of HARQ processes) in a specified message and send it to the eNB, and the eNB obtains the resource scheduling information by parsing the message. However, when the resource scheduling information is carried When the scheduling information message is a message that UE transparently transmits to EPC through eNB (for example, a message including an Attach Request), eNB will not parse the transparent transmission message, but directly transparently transmit it to EPC. In this case In this case, the message can be parsed in the EPC (for example, the Mobility Management Entity (MME, Mobility Management Entity) in the EPC), and the obtained resource scheduling information can be sent to the eNB. Therefore, the eNB can obtain the resource scheduling information through the information reported by the UE. The maximum number of HARQ processes can also be obtained from the EPC.

Specifically, when the eNB obtains the maximum number of HARQ processes through the information reported by the UE, at S110, the eNB may receive the first message sent by the UE, and the first message carries information indicating the maximum number of HARQ processes that the UE can support. The information about the maximum number of HARQ processes, so that the eNB can obtain the information about the maximum number of HARQ processes from the first message, so as to determine the maximum number of HARQ processes. Therefore, in the embodiment of the present invention, the determination of resource scheduling information may include:

receiving the first message carrying the resource scheduling information sent by the target user;

According to the first message, determine the resource scheduling information.

In the embodiment of the present invention, the process of the UE reporting the maximum number of HARQ processes to the eNB may be performed in the RRC (Radio Resource Control) connection establishment process, the UE capability reporting process, or the RRC connection reconfiguration process. Therefore, the first message includes the RRC establishment Complete message, user capability information message or RRC reconfiguration complete message.

It should be understood that the messages listed above as the first messages are only exemplary descriptions of the present invention, and other UEs send before accepting resource scheduling by the eNB, and messages that may be parsed by the eNB and that can carry resource scheduling information all fall into the within the protection scope of the present invention. Descriptions of the same or similar cases are omitted below.

In S120, the eNB can make the number of HARQ processes allocated to the UE not exceed the maximum number of HARQ processes reported by the UE, so the resource scheduling for the target user includes:

Make the number of HARQ processes allocated to the target user less than or equal to the maximum number of HARQ processes.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the maximum number of HARQ processes reported by the target user, the number of HARQ processes allocated to the target user is less than or equal to the number of HARQ processes that the target user can support. The maximum number of HARQ processes does not limit the maximum rate that the UE can support. In the case of inconsistent data rate requirements for M2M applications, if the maximum data rate required by the application is low, the user can reduce the user's data rate reported to the base station. The maximum number of HARQ processes supported, so that the maximum number of HARQ processes allocated by the base station to users is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of user equipment; if the maximum data rate required by the application is high, then The user can increase the maximum number of HARQ processes supported by the user reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user also increases, thereby increasing the maximum data rate, not limited to the unified maximum data rate of all users Speed, so as to meet the different requirements of different applications for data rates, which can save costs and facilitate application support.

In the embodiment of the present invention, the eNB can also store the information on the maximum number of HARQ processes, and can record the information on the maximum number of HARQ processes according to the relationship between the information on the maximum number of HARQ processes reported by the UE and the user identifier of the UE, and generate a database , when the UE performs service access through the eNB again (for example, the UE sends an uplink data packet to the EPC, or the EPC sends a downlink data packet to the UE), the maximum Number of HARQ processes. Therefore, the determined resource scheduling information also includes:

generating a first resource scheduling information database based on the correspondence between the resource scheduling information and the user identifier of the target user;

receiving a second message carrying the user identifier sent by the target user or the network side;

According to the user identifier, resource scheduling information corresponding to the user identifier is acquired from the first resource scheduling information database.

In the embodiment of the present invention, the second message may be a resource request (Resource Request) sent by UE or EPC to trigger eNB to perform resource scheduling, for example, RRC connection establishment complete message, RRC connection reconfiguration complete message or initial context Create a request (Initial Context Setup Request).

It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for the case of being disconnected from the network side, the UE only needs to report the maximum number of HARQ processes once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment .

On the other hand, when the eNB acquires the maximum number of HARQ processes from the EPC, at S110, the eNB may use the transparent transmission message sent by the UE to carry the maximum number of HARQ processes information indicating the maximum number of HARQ processes that the UE can support (for example, , Attach Request) is forwarded to the EPC, and the EPC parses the transparent transmission message, and after obtaining the information on the maximum number of HARQ processes, sends the information on the maximum number of HARQ processes to the eNB. Therefore, the determination of resource scheduling information may include:

receiving a third message carrying the resource scheduling information sent by the target user;

Forwarding the third message to the network side;

receiving a fourth message carrying the resource scheduling information sent by the network side;

According to the fourth message, determine the resource scheduling information.

In the embodiment of the present invention, the third message may be, for example, an Attach Request (carrying resource scheduling information), and the UE may send a message including the Attach Request to the eNB, such as an RRC establishment complete message, and the eNB receives the RRC establishment complete message , the Attach Request message is not parsed, but the Attach Request is carried in, for example, an initial user information message (Initial UEmessage) and sent to the EPC. The fourth message may be, for example, an initial context setup request message (Initial Context Setup Request). Therefore, the third message can be regarded as transparently transmitted to the network side, and the resource scheduling information is obtained by parsing the fourth message only after receiving the fourth message from the network side.

It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In S120, the eNB can make the number of HARQ processes allocated to the UE not exceed the maximum number of HARQ processes, so resource scheduling for the target user includes:

According to the information about the maximum number of HARQ processes, assign HARQ processes to the target user, where the number of HARQ processes is less than or equal to the maximum number of HARQ processes.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the maximum number of HARQ processes reported by the target user, the number of HARQ processes allocated to the target user is less than or equal to the number of HARQ processes that the target user can support. The maximum number of HARQ processes does not limit the maximum rate that the UE can support. In the case of inconsistent data rate requirements for M2M applications, if the maximum data rate required by the application is low, the user can reduce the user's data rate reported to the base station. The maximum number of HARQ processes supported, so that the maximum number of HARQ processes allocated by the base station to users is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of user equipment; if the maximum data rate required by the application is high, then The user can increase the maximum number of HARQ processes supported by the user reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user also increases, thereby increasing the maximum data rate, not limited to the unified maximum data rate of all users Speed, so as to meet the different requirements of different applications for data rates, which can save costs and facilitate application support.

Optionally, in this embodiment of the present invention, the EPC may also store the information on the maximum number of HARQ processes, and may record the maximum number of HARQ processes according to the relationship between the information on the maximum number of HARQ processes reported by the UE and the user identifier of the UE information to generate a database, and when the UE performs service access through the eNB again (for example, the EPC receives the service request Service Request sent by the eNB), it can directly obtain the maximum HARQ from the database according to the user identification included in the Service Request process number and send it to eNB. Therefore, the determination of resource scheduling information may also include:

A fifth message carrying the user identifier of the target user sent to the network side, where the user identifier is used by the network side to obtain from a second resource scheduling information database generated based on the correspondence between the resource scheduling information and the user identifier Resource scheduling information corresponding to the user ID.

In this embodiment of the present invention, the fifth message may be a message including a service request (Service Request), such as an Initial UE message. It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for the case of being disconnected from the network side, the UE only needs to report the maximum number of HARQ processes once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment .

In the embodiment of the present invention, the maximum number of HARQ processes may be the maximum number of HARQ processes supported by the uplink and downlink, and may also include the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink), and the maximum number of HARQ processes supported by the downlink. The number of processes (MaxHARQ Process Number-Downlink); more specifically, the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink) can be divided into frequency division duplex (FDD) systems and time division duplex (TDD) systems, The maximum number of HARQ processes supported by the FDD system uplink (MaxHARQProcess Number-Uplink-FDD), the maximum number of HARQ processes supported by the TDD system uplink (Max HARQ ProcessNumber-Uplink-TDD); the maximum number of HARQ processes supported by the downlink (Max HARQ Process Number- Downlink) can be divided into FDD and TDD, the maximum number of HARQ processes supported by the downlink of the FDD system (Max HARQProcess Number-Downlink-FDD), and the maximum number of HARQ processes supported by the downlink of the TDD system (Max HARQProcess Number-Downlink-TDD).

Therefore, the maximum number of HARQ processes includes the maximum number of uplink HARQ processes, the maximum number of downlink HARQ processes, the maximum number of uplink HARQ processes in a frequency division duplex FDD system, the maximum number of uplink HARQ processes in a time division duplex TDD system, and the maximum number of downlink HARQ processes in an FDD system , The maximum number of downlink HARQ processes in the TDD system.

In this way, the flexibility of resource scheduling is further increased.

Situation (2)

In the embodiment of the present invention, the UE may carry resource scheduling information (for example, subframe information used to indicate whether a subframe may carry a downlink control channel) in a specified message and send it to the eNB, and the eNB obtains it by parsing the message The resource scheduling information, however, when the message carrying the resource scheduling information is a message (for example, a message containing an Attach Request) transparently transmitted by the UE to the EPC through the eNB, the eNB will not parse the transparently transmitted message, but directly It is transparently transmitted to the EPC. In this case, the EPC (for example, the MME in the EPC) can analyze the message and send the obtained resource scheduling information to the eNB. Therefore, the eNB can obtain the resource scheduling information through the information reported by the UE. The subframe information may also be obtained from the EPC. Moreover, the eNB can also determine the subframe information by itself, and then notify the UE.

Specifically, when the eNB obtains the subframe information through the information reported by the UE, at S110, the eNB may receive the first message sent by the UE, the first message carrying the subframe information representing the subframe that the UE wishes to monitor, Therefore, the eNB can obtain the subframe information from the first message, therefore, in the embodiment of the present invention, determining the resource scheduling information may include:

receiving the first message carrying the resource scheduling information sent by the target user;

According to the first message, determine the resource scheduling information.

Specifically, the UE may report the subframe information in the form of a bitmap (bitmap) representing the subframe it wishes to monitor the downlink control channel. Taking FDD as an example, an 8-bit bitmap can be used to indicate that it wants to monitor the subframe information of the downlink control channel. The corresponding bit of the bitmap is 1, indicating that the UE wants to monitor the downlink channel on the corresponding subframe, and the corresponding bit of the bitmap is 0, indicating that the UE does not It is desired to monitor the downlink channel on the corresponding subframe.

In the embodiment of the present invention, the process for the UE to report the subframe information to the eNB can be performed in the RRC connection establishment process, the UE capability reporting process or the RRC connection reconfiguration process. Therefore, the first message includes the RRC establishment complete message, the user capability Information message or RRC reconfiguration complete message.

In S120, the eNB can carry the downlink control channel in the subframe corresponding to the subframe information, so that the UE can only monitor the downlink control channel in the subframe corresponding to the subframe information, and monitor the downlink control channel in other subframes. Choose to sleep, so the resource scheduling for this target user includes:

According to the subframe information, the downlink control channel is carried in a subframe corresponding to the subframe information.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the subframe information reported by the target user, the downlink control channel is carried in the subframe that the target user wants to monitor, so that the target user can The downlink control channel is only monitored in specified subframes, and sleep is selected in other subframes, so that the UE does not need to monitor channels in all downlink subframes to receive scheduling information. For low-cost LTE MTC UEs with lower requirements on time delay and data rate but higher energy consumption requirements, this reduces energy consumption, thereby reducing the cost of user equipment.

Optionally, in this embodiment of the present invention, at S110, the eNB may also store the subframe information, and record the subframe information according to the relationship between the subframe information reported by the UE and the user identifier of the UE, and generate database, when the UE performs service access again through the eNB (for example, the UE sends an uplink data packet to the EPC, or the EPC sends a downlink data packet to the UE), the UE can directly obtain the Subframe information. Therefore, the determined resource scheduling information also includes:

generating a first resource scheduling information database based on the correspondence between the resource scheduling information and the user identifier of the target user;

receiving a second message carrying the user identifier sent by the target user or the network side;

According to the user identifier, resource scheduling information corresponding to the user identifier is acquired from the first resource scheduling information database.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for disconnection from the network side, the UE only needs to report the subframe information once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment.

On the other hand, when the eNB obtains the subframe information from the EPC, at S110, the eNB may transmit the transparent transmission message (for example, Attach Request) that carries the subframe information sent by the UE to indicate whether the subframe may carry the downlink control channel Forward it to the EPC, and the EPC analyzes the transparent transmission message, and after obtaining the subframe information, sends the subframe information to the eNB. Therefore, the determination of resource scheduling information may include:

receiving a third message carrying the resource scheduling information sent by the target user;

Forwarding the third message to the network side;

receiving a fourth message carrying the resource scheduling information sent by the network side;

According to the fourth message, determine the resource scheduling information.

In the embodiment of the present invention, the third message may be, for example, an Attach Request, and the UE may send a message including the Attach Request to the eNB, such as an RRC establishment complete message, and the eNB does not parse the Attach Request after receiving the RRC establishment complete message Instead, the Attach Request (carrying resource scheduling information) is carried in, for example, an Initial UE message and sent to the EPC. The fourth message may be, for example, an Initial Context SetupRequest.

In S120, the eNB can carry the downlink control channel in the subframe corresponding to the subframe information, so that the UE can monitor the downlink control channel only in the subframe corresponding to the subframe information carried in the first message sent to the eNB. control channel, and choose to sleep on other subframes, so the resource scheduling for the target user includes:

According to the subframe information, the downlink control channel is carried in a subframe corresponding to the subframe information.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the subframe information reported by the target user, the downlink control channel is carried in the subframe that the target user wants to monitor, so that the target user can The downlink control channel is only monitored in specified subframes, and sleep is selected in other subframes, so that the UE does not need to monitor channels in all downlink subframes to receive scheduling information. For low-cost LTE MTC UEs with lower requirements on time delay and data rate but higher energy consumption requirements, this reduces energy consumption, thereby reducing the cost of user equipment.

Optionally, in this embodiment of the present invention, the EPC can also save the subframe information, and can record the subframe information according to the relationship between the subframe information reported by the UE and the user identifier of the UE, and generate a database. The UE performs service access again. For example, when the EPC receives the service request (Service Request) sent by the UE, it can directly obtain the subframe information from the database according to the user ID included in the Service Request, and send it to the eNB. Therefore, the determination of resource scheduling information may also include:

A fifth message carrying the user identifier of the target user sent to the network side, where the user identifier is used by the network side to obtain from a second resource scheduling information database generated based on the correspondence between the resource scheduling information and the user identifier Resource scheduling information corresponding to the user ID. In this embodiment of the present invention, the fifth message may be a message including a Service Request, such as an Initial UE message.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for disconnection from the network side, the UE only needs to report the subframe information once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment.

In the above embodiments, the subscriber identity may include a mobile subscriber phone number (MSISDN, MobileSubscriber Integrated Services Digital Network), an international mobile subscriber identity (IMSI, International Mobile Station Equipment Identity), an international mobile station equipment identity (IMEI, International Mobile Subscriber Identity), Globally Unique Temporary Identifier (GUTI, Globally Unique Temporary Identifier), and Temporary Mobile Subscriber Identifier (TMSI, Temporary MobileSubscriber Identifier). at least one of the It should be understood that the individual information listed above as the user identifier is only an exemplary description of the present invention, and other information that can uniquely represent the user equipment in the network falls within the protection scope of the present invention. Descriptions of the same or similar cases are omitted below.

When the eNB determines the subframe information by itself and then notifies the UE, at S110, the eNB determines the subframe information by itself on the premise of satisfying the UE's delay and data rate requirements according to needs and scheduling flexibility. Therefore, the determined resource scheduling information includes:

determining the subframe information;

Send a sixth message carrying the subframe information to the target user, and the subframe corresponding to the subframe information is used by the target user to monitor the downlink control channel.

In the embodiment of the present invention, the process of the eNB delivering the subframe information to the UE may be performed in the RRC connection reconfiguration procedure, therefore, the sixth message may include the RRC reconfiguration complete message. It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In S120, the eNB may carry the downlink control channel in the subframe corresponding to the subframe information, and the UE may only monitor the downlink control channel in the subframe corresponding to the subframe information, and choose to sleep in other subframes, Therefore, the resource scheduling for the target user includes:

According to the subframe information, the downlink control channel is carried in a subframe corresponding to the subframe information.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling on the target user, by sending the subframe information to the target user, the downlink control channel is carried in the subframe corresponding to the subframe information , enabling the target user to monitor the downlink control channel only in specified subframes, and choose to sleep in other subframes, so that the UE does not need to monitor channels in all downlink subframes to receive scheduling information. For low-cost LTE MTC UEs with lower requirements on time delay and data rate but higher energy consumption requirements, this reduces energy consumption, thereby reducing the cost of user equipment.

It should be understood that, in the implementation of the present invention, the term "and/or" herein is only an association relationship describing associated objects, which means that there may be three relationships, for example, A and/or B, which may mean that A exists alone , both A and B exist, and B exists alone. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship. That is, the resource scheduling information may only include the maximum number of HARQ processes or subframe information to achieve the technical effects described in the above case (1) or case (2), respectively, or may include both to realize the cases (1) and The two technical effects expressed in case (2). Hereinafter, descriptions of the same or similar cases are omitted.

FIG. 2 shows a schematic flowchart of a method 200 for resource scheduling according to an embodiment of the present invention, expressed from the perspective of a UE. As shown in Figure 2, the method 200 includes:

S210. Determine resource scheduling information, where the resource scheduling information includes information on the maximum number of HARQ processes used to indicate the maximum number of hybrid automatic repeat request HARQ processes that the target user can support and/or used to indicate whether the subframe may carry downlink control Channel subframe information;

S220. Accept resource scheduling of the base station according to the resource scheduling information.

Moreover, in the embodiment of the present invention, the resource scheduling information may include the maximum number of hybrid automatic repeat request (HARQ) processes of the UE and/or subframe information used to indicate whether the subframe may bear the downlink control channel.

Specifically, the UE may report resource scheduling information to the eNB or EPC, so that the eNB performs resource scheduling according to the resource scheduling information. Moreover, when the resource scheduling information is subframe information, the eNB can determine the subframe information by itself and issue it to the UE, so that the UE can monitor the downlink control channel in a specified subframe according to the subframe. In the embodiment of the present invention, the resource scheduling information may include information on the maximum number of HARQ processes used to indicate the maximum number of HARQ processes supported by the UE (hereinafter referred to as the maximum number of HARQ processes) and/or used to indicate whether the subframe may carry Subframe information of the downlink control channel. Since only one category of UE is defined for the UE, the modulation levels supported by the UE are limited, thereby determining the maximum TB size supported by the UE and the modulation and coding methods that can be used by the UE. Therefore, the maximum number of HARQ processes that the UE can support determines the maximum rate that the UE can support. In addition, according to the subframe information, the UE may monitor channels only on specified downlink subframes that may carry downlink control channels, and receive scheduling information. Therefore, the eNB can perform different scheduling according to the content included in the resource scheduling information (so that the number of HARQ processes allocated to the UE does not exceed the maximum number of HARQ processes indicated by the maximum number of HARQ processes information or bear the downlink control channel in the subframe information corresponding subframe). In the following, the case (3) in which the resource scheduling information includes information about the maximum number of HARQ processes supported by the UE and the case (4) in which the resource scheduling information includes the subframe information will be described respectively.

Situation(3)

In the embodiment of the present invention, the UE sends the resource scheduling information (for example, information on the maximum number of HARQ processes) in a specified message to the eNB, and the eNB obtains the resource scheduling information by parsing the message. However, when the resource scheduling information is carried When the information message is a message (for example, a message containing an Attach Request) that the UE transparently transmits to the EPC through the eNB, the eNB will not parse the transparently transmitted message, but directly transparently transmit it to the EPC. In this case, you can The EPC (for example, the MME in the EPC) analyzes the message and sends the obtained resource scheduling information to the eNB. Therefore, the UE can report the maximum number of HARQ processes to the eNB or to the EPC.

Specifically, when the UE reports the information on the maximum number of HARQ processes to the eNB, at S210, the UE may determine the maximum number of HARQ processes that it can support, and send a first message to the eNB, where the first message carries information indicating the The information about the maximum number of HARQ processes of the maximum number of HARQ processes, so that the eNB can obtain the information about the maximum number of HARQ processes supported by the UE from the first message, so as to determine the maximum number of HARQ processes. Therefore, in the embodiment of the present invention, The method also includes:

Sending the first message carrying the resource scheduling information to the base station to notify the base station to perform resource scheduling according to the resource scheduling information.

In the embodiment of the present invention, the process of the UE reporting the maximum number of HARQ processes to the eNB can be performed in the RRC connection establishment process, the UE capability reporting process or the RRC connection reconfiguration process. Therefore, the first message includes the RRC establishment complete message, the user Capability information message or RRC reconfiguration complete message.

In S220, the resource scheduling performed by the eNB accepted by the UE is such that the maximum number of HARQ processes allocated by the eNB to the UE does not exceed the maximum number of HARQ processes reported by the UE. Therefore, according to the resource scheduling information, the resource scheduling of the base station is accepted, including:

and managing the HARQ processes allocated by the base station according to the information about the maximum number of HARQ processes, where the number of HARQ processes is less than or equal to the maximum number of HARQ processes. In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the maximum number of HARQ processes reported by the target user, the number of HARQ processes allocated to the target user is less than or equal to the number of HARQ processes that the target user can support. The maximum number of HARQ processes does not limit the maximum rate that the UE can support. In the case of inconsistent data rate requirements for M2M applications, if the maximum data rate required by the application is low, the user can reduce the user's data rate reported to the base station. The maximum number of HARQ processes supported, so that the maximum number of HARQ processes allocated by the base station to users is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of user equipment; if the maximum data rate required by the application is high, then The user can increase the maximum number of HARQ processes supported by the user reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user also increases, thereby increasing the maximum data rate, not limited to the unified maximum data rate of all users Speed, so as to meet the different requirements of different applications for data rates, which can save costs and facilitate application support.

In the embodiment of the present invention, the eNB can also store the information on the maximum number of HARQ processes, and can record the information on the maximum number of HARQ processes according to the relationship between the information on the maximum number of HARQ processes reported by the UE and the user identifier of the UE, and generate a database , when the UE performs service access through the eNB again (for example, the UE sends an uplink data packet to the EPC, or the EPC sends a downlink data packet to the UE), the maximum Number of HARQ processes. Therefore, the method also includes:

Sending a second message carrying a user identifier to the base station, where the user identifier is used by the base station to obtain a resource corresponding to the user identifier from a first resource scheduling information database generated based on the correspondence between the resource scheduling information and the user identifier. Resource scheduling information.

In the embodiment of the present invention, the second message may be a Resource Request sent by the UE to the eNB for triggering resource scheduling of the eNB, for example, an RRC connection establishment complete message or an RRC connection reconfiguration complete message. It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for the case of being disconnected from the network side, the UE only needs to report the maximum number of HARQ processes once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment .

On the other hand, when the UE reports the maximum number of HARQ processes to the EPC, at S210, the UE may, through the eNB, carry a transparent transmission message (such as , Attach Request) to the EPC, and the EPC, after analyzing the transparent transmission message and obtaining the information on the maximum number of HARQ processes, sends the information on the maximum number of HARQ processes to the eNB. Therefore, the method also includes:

Sending a third message carrying the resource scheduling information to the network side to instruct the network side to deliver the resource scheduling information to the base station.

In this embodiment of the present invention, the third message may be, for example, an Attach Request. In this case, the UE may send a message including the Attach Request to the eNB, such as an RRC establishment complete message. After receiving the RRC establishment complete message, the eNB does not The Attach Request message included in it is parsed, and the Attach Request (carrying resource scheduling information) is carried in, for example, an Initial UEmessage and sent to the EPC. It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In S220, the resource scheduling performed by the eNB accepted by the UE is that the maximum number of HARQ processes allocated by the eNB to the UE does not exceed the maximum number of HARQ processes reported by the UE.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the maximum number of HARQ processes reported by the target user, the number of HARQ processes allocated to the target user is less than or equal to the number of HARQ processes that the target user can support. The maximum number of HARQ processes does not limit the maximum rate that the UE can support. In the case of inconsistent data rate requirements for M2M applications, if the maximum data rate required by the application is low, the user can reduce the user's data rate reported to the base station. The maximum number of HARQ processes supported, so that the maximum number of HARQ processes allocated by the base station to users is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of user equipment; if the maximum data rate required by the application is high, then The user can increase the maximum number of HARQ processes supported by the user reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user also increases, thereby increasing the maximum data rate, not limited to the unified maximum data rate of all users Speed, so as to meet the different requirements of different applications for data rates, which can save costs and facilitate application support.

Optionally, in this embodiment of the present invention, the EPC may also store the information on the maximum number of HARQ processes, and may record the maximum number of HARQ processes according to the relationship between the information on the maximum number of HARQ processes reported by the UE and the user identifier of the UE information, generate a database, and when the UE performs service access through the eNB again (for example, the EPC receives the Service Request sent by the eNB), it can directly obtain the maximum number of HARQ processes from the database according to the user ID included in the Service Request , and send it to the eNB. Therefore, the method may also include:

Sending a fourth message carrying a user identifier to the network side, where the user identifier is used by the network side to obtain information related to the user identifier from a second resource scheduling information database generated based on the correspondence between the resource scheduling information and the user identifier. Corresponding resource scheduling information.

In this embodiment of the present invention, the fourth message may be a Service Request message. It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for the case of being disconnected from the network side, the UE only needs to report the maximum number of HARQ processes once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment .

In the embodiment of the present invention, the maximum number of HARQ processes may be the maximum number of HARQ processes supported by the uplink and downlink, and may also include the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink), and the maximum number of HARQ processes supported by the downlink. The number of processes (Max HARQ Process Number-Downlink); more specifically, the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink) can be divided into frequency division duplex (FDD) systems and time division duplex (TDD) systems. , the maximum number of HARQ processes supported by the uplink of the FDD system (MaxHARQProcess Number-Uplink-FDD), the maximum number of HARQ processes supported by the uplink of the TDD system (Max HARQ ProcessNumber-Uplink-TDD); the maximum number of HARQ processes supported by the downlink (Max HARQ Process Number -Downlink) can be divided according to FDD and TDD, the maximum number of HARQ processes supported by the downlink of the FDD system (Max HARQProcess Number-Downlink-FDD), and the maximum number of HARQ processes supported by the downlink of the TDD system (Max HARQProcess Number-Downlink-TDD).

Therefore, the maximum number of HARQ processes includes the maximum number of uplink HARQ processes, the maximum number of downlink HARQ processes, the maximum number of uplink HARQ processes in a frequency division duplex FDD system, the maximum number of uplink HARQ processes in a time division duplex TDD system, and the maximum number of downlink HARQ processes in an FDD system , The maximum number of downlink HARQ processes in the TDD system.

In this way, the flexibility of resource scheduling is further increased.

Situation(4)

In the embodiment of the present invention, the UE may carry resource scheduling information (for example, subframe information used to indicate whether a subframe may carry a downlink control channel) in a specified message and send it to the eNB, and the eNB obtains it by parsing the message The resource scheduling information, however, when the message carrying the resource scheduling information is a message (for example, a message containing an Attach Request) transparently transmitted by the UE to the EPC through the eNB, the eNB will not parse the transparently transmitted message, but directly It is transparently transmitted to the EPC. In this case, the EPC (for example, the MME in the EPC) can analyze the message and send the obtained resource scheduling information to the eNB. Therefore, the UE can report the subframe information to the eNB , can also be reported to the EPC, and the UE can also obtain the subframe information from the eNB.

Specifically, when the UE reports the subframe information to the eNB, at S210, the UE may send a first message to the eNB, and the first message carries subframe information representing a subframe that the UE wishes to monitor, so that the eNB may Obtain the subframe information from the first message, therefore, in this embodiment of the present invention, the method further includes:

Sending the first message carrying the resource scheduling information to the base station to notify the base station to perform resource scheduling according to the resource scheduling information.

Specifically, the UE may report the subframe information in the form of a bitmap (bitmap) representing the subframe it wishes to monitor the downlink control channel. Taking FDD as an example, an 8-bit bitmap can be used to indicate that it wants to monitor the subframe information of the downlink control channel. The corresponding bit of the bitmap is 1, indicating that the UE wants to monitor the downlink channel on the corresponding subframe, and the corresponding bit of the bitmap is 0, indicating that the UE does not It is desired to monitor the downlink channel on the corresponding subframe.

In the embodiment of the present invention, the process for the UE to report the maximum number of HARQ processes to the eNB can be performed in the RRC connection establishment process, the UE capability reporting process or the RRC connection reconfiguration process. Therefore, the first message includes the RRC establishment complete message, the user Capability information message or RRC reconfiguration complete message.

The eNB can carry the downlink control channel in the subframe corresponding to the subframe information, so that at S220, the UE can monitor the downlink control channel only in the subframe corresponding to the subframe information, and select Sleep, so the resource scheduling that the base station accepts according to the resource scheduling information includes:

According to the subframe information, monitor the downlink control channel on the subframe corresponding to the subframe information.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the subframe information reported by the target user, the downlink control channel is carried in the subframe that the target user wants to monitor, so that the target user can The downlink control channel is only monitored in specified subframes, and sleep is selected in other subframes, so that the UE does not need to monitor channels in all downlink subframes to receive scheduling information. For low-cost LTE MTC UEs with lower requirements on time delay and data rate but higher energy consumption requirements, this reduces energy consumption, thereby reducing the cost of user equipment.

Optionally, in this embodiment of the present invention, at S210, the eNB may also save the subframe information, and record the subframe information according to the relationship between the subframe information reported by the UE and the UE's user identifier, and generate database, when the UE performs service access again through the eNB (for example, the UE sends an uplink data packet to the EPC, or the EPC sends a downlink data packet to the UE), the UE can directly obtain the Subframe information. Therefore, the method also includes:

Sending a second message carrying a user identifier to the base station, where the user identifier is used by the base station to obtain a resource corresponding to the user identifier from a first resource scheduling information database generated based on the correspondence between the resource scheduling information and the user identifier. Resource scheduling information.

In the embodiment of the present invention, the second message may be a Resource Request sent by the UE to the eNB for triggering resource scheduling of the eNB, for example, an RRC connection establishment complete message or an RRC connection reconfiguration complete message.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for disconnection from the network side, the UE only needs to report the subframe information once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment.

On the other hand, when the UE reports the subframe information to the EPC, at S210, the UE may, through the eNB, transmit the transparent transmission message (for example, an attach request message) carrying the subframe information used to indicate whether the subframe may carry the downlink control channel ) is transparently transmitted to the EPC through the eNB, and the EPC analyzes the transparently transmitted message, and after obtaining the subframe information, sends the subframe information to the eNB. Therefore, the method may also include:

Sending a third message carrying the resource scheduling information to the network side to instruct the network side to deliver the resource scheduling information to the base station.

In this embodiment of the present invention, the third message may be, for example, an Attach Request. In this case, the UE may send a message including the Attach Request to the eNB, such as an RRC establishment complete message. After receiving the RRC establishment complete message, the eNB does not The Attach Request message included in it is parsed, and the Attach Request (carrying resource scheduling information) is carried in, for example, an Initial UEmessage and sent to the EPC.

The eNB may carry the downlink control channel in the subframe corresponding to the subframe information, so that at S220, the UE may monitor the downlink control channel only in the subframe corresponding to the subframe information carried in the first message sent to the eNB. channel, and choose to sleep on other subframes, so the resource scheduling performed by the base station according to the resource scheduling information includes:

According to the subframe information, monitor the downlink control channel on the subframe corresponding to the subframe information.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the subframe information reported by the target user, the downlink control channel is carried in the subframe that the target user wants to monitor, so that the target user can The downlink control channel is only monitored in specified subframes, and sleep is selected in other subframes, so that the UE does not need to monitor channels in all downlink subframes to receive scheduling information. For low-cost LTE MTC UEs with lower requirements on time delay and data rate but higher energy consumption requirements, this reduces energy consumption, thereby reducing the cost of user equipment.

Optionally, in this embodiment of the present invention, the EPC can also save the subframe information, and can record the subframe information according to the relationship between the subframe information reported by the UE and the user identifier of the UE, and generate a database. When the UE performs service access through the EPC again (for example, the EPC receives the service request Service Request sent by the eNB), it can directly obtain the subframe information from the database according to the user identifier included in the Service Request of the UE, and send the to eNB. Therefore, the method may also include:

Sending a fourth message carrying a user identifier to the network side, where the user identifier is used by the network side to obtain information related to the user identifier from a second resource scheduling information database generated based on the correspondence between the resource scheduling information and the user identifier. Corresponding resource scheduling information.

In this embodiment of the present invention, the fourth message may be a Service Request message.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for disconnection from the network side, the UE only needs to report the subframe information once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment.

When the UE obtains the subframe information from the eNB, the eNB determines the subframe information by itself on the premise of satisfying the UE delay and data rate requirements according to the needs and flexibility of scheduling. In S210, the UE receives the subframe information issued by the eNB. frame information. Therefore, the determined resource scheduling information includes:

receiving a fifth message carrying the subframe information sent by the base station;

According to the fifth message, the subframe information is determined.

In the embodiment of the present invention, the process of the eNB delivering the subframe information to the UE may be performed in the RRC connection reconfiguration procedure, therefore, the sixth message may include the RRC reconfiguration complete message. It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In S120, the UE may only monitor the downlink control channel in the subframe corresponding to the subframe information, and choose to sleep in other subframes. Therefore, resource scheduling for the target user includes:

According to the subframe information, monitor the downlink control channel on the subframe corresponding to the subframe information.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling on the target user, by sending the subframe information to the target user, the downlink control channel is carried in the subframe corresponding to the subframe information , enabling the target user to monitor the downlink control channel only in specified subframes, and choose to sleep in other subframes, so that the UE does not need to monitor channels in all downlink subframes to receive scheduling information. For low-cost LTE MTC UEs with lower requirements on time delay and data rate but higher energy consumption requirements, this reduces energy consumption, thereby reducing the cost of user equipment.

FIG. 3 shows a schematic flow chart of a resource scheduling method 300 according to an embodiment of the present invention, expressed from an EPC perspective. As shown in Figure 3, the method 300 includes:

S310. Receive a first message carrying resource scheduling information sent by the target user, where the resource scheduling information includes information on the maximum number of HARQ processes and/or used to indicate the maximum number of HARQ processes that the target user can support. Subframe information used to indicate whether the subframe may carry a downlink control channel;

S320. Determine the resource scheduling information according to the first message;

S330. Send a second message carrying the resource scheduling information to the base station, so as to notify the base station to perform resource scheduling on the target user according to the resource scheduling information.

Moreover, in the embodiment of the present invention, the resource scheduling information may include information on the maximum number of HARQ processes used to indicate the maximum number of HARQ processes that the UE can support and/or subframe information used to indicate whether the subframe may carry the downlink control channel .

Specifically, at S310, the EPC may receive the first message (for example, Attach Request) sent by the UE, in which the first message carries resource scheduling information of the UE (including maximum HARQ process number information and/or subframe information ).

At S320, the EPC may obtain the resource scheduling information by parsing the first message.

At S330, the EPC may send a second message carrying the resource scheduling information to the eNB, so that the eNB acquires the resource scheduling information, and performs resource scheduling on the target user according to the resource scheduling information (for example, making the HARQ process allocated to the UE The maximum number of is less than or equal to the information about the maximum number of HARQ processes, and/or bear the downlink control channel in the subframe corresponding to the subframe information).

In the embodiment of the present invention, the first message may be, for example, an Attach Request (carrying resource scheduling information), and the UE may send a message including the Attach Request to the eNB, such as an RRC establishment complete message, and the eNB receives the RRC establishment complete message , without parsing the Attach Request message contained therein, but carrying the AttachRequest in, for example, an initial user message (Initial UE message) and sending it to the EPC, and the second message may be, for example, an initial context setup request message (Initial Context Setup Request). It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling for the target user, according to the maximum number of HARQ processes reported by the target user, the number of HARQ processes allocated to the target user is less than or equal to the number of HARQ processes that the target user can support. The maximum number of HARQ processes does not limit the maximum rate that the UE can support. In the case of inconsistent data rate requirements for M2M applications, if the maximum data rate required by the application is low, the user can reduce the user's data rate reported to the base station. The maximum number of HARQ processes supported, so that the maximum number of HARQ processes allocated by the base station to users is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of user equipment; if the maximum data rate required by the application is high, then The user can increase the maximum number of HARQ processes supported by the user reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user also increases, thereby increasing the maximum data rate, not limited to the unified maximum data rate of all users Speed, so as to meet the different requirements of different applications for data rates, which can save costs and facilitate application support. In addition, when the base station performs resource scheduling for the target user, according to the subframe information reported by the target user, the downlink control channel is carried in the subframe that the target user wants to monitor, so that the target user can monitor the downlink control channel only in the specified subframe, And sleep is selected in other subframes, so that the UE does not need to monitor channels in all downlink subframes to receive scheduling information. For low-cost LTE MTC UEs with lower requirements on time delay and data rate but higher energy consumption requirements, this reduces energy consumption, thereby reducing the cost of user equipment.

Optionally, in this embodiment of the present invention, the EPC may also store the information on the maximum number of HARQ processes, and may record the maximum number of HARQ processes according to the relationship between the information on the maximum number of HARQ processes reported by the UE and the user identifier of the UE information to generate a database, and when the UE performs service access again through the EPC (for example, the EPC receives the Service Request sent by the eNB), it can directly obtain the UE from the database according to the user ID included in the Service Request of the UE. The maximum number of HARQ processes, and sent to eNB. Therefore, the method also includes:

According to the user identifier, the resource scheduling information corresponding to the user identifier is obtained from the resource scheduling information database.

In the embodiment of the present invention, the third message may be a message including a Service Request, such as an Initial UE message. It should be understood that the messages listed above are only exemplary descriptions of the present invention, and the present invention is not limited thereto.

In this way, according to the resource scheduling method of the embodiment of the present invention, except for disconnection from the network side, the UE only needs to report the subframe information once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment.

In the embodiment of the present invention, the maximum number of HARQ processes may be the maximum number of HARQ processes supported by the uplink and downlink, and may also include the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink), and the maximum number of HARQ processes supported by the downlink. The number of processes (Max HARQ Process Number-Downlink); more specifically, the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink) can be divided into frequency division duplex (FDD) systems and time division duplex (TDD) systems. , the maximum number of HARQ processes supported by the uplink of the FDD system (Max HARQProcess Number-Uplink-FDD), the maximum number of HARQ processes supported by the uplink of the TDD system (Max HARQ ProcessNumber-Uplink-TDD); the maximum number of HARQ processes supported by the downlink (Max HARQ Process Number-Uplink-TDD) Number-Downlink) can be divided into FDD and TDD, the maximum number of HARQ processes supported by the downlink of the FDD system (Max HARQProcess Number-Downlink-FDD), and the maximum number of HARQ processes supported by the downlink of the TDD system (Max HARQProcess Number-Downlink-TDD).

Therefore, the maximum number of HARQ processes includes the maximum number of uplink HARQ processes, the maximum number of downlink HARQ processes, the maximum number of uplink HARQ processes in a frequency division duplex FDD system, the maximum number of uplink HARQ processes in a time division duplex TDD system, and the maximum number of downlink HARQ processes in an FDD system , The maximum number of downlink HARQ processes in the TDD system.

In this way, the flexibility of resource scheduling is further increased.

Fig. 4 shows the interaction diagram of the resource scheduling method according to the embodiment of the present invention. As shown in Fig. 4, the eNB can determine the resource scheduling information of the target user in three ways (mode 1, mode 2, mode 3). The flow of resource scheduling in each mode will be described.

way 1

In S401, the UE determines resource scheduling information (including maximum HARQ process number information indicating the maximum number of HARQ processes that the UE can support and/or subframe information indicating whether a subframe may carry a downlink control channel).

In S402, the UE carries the resource scheduling information in, for example, an RRC establishment complete message, a user capability information message or an RRC reconfiguration complete message, and sends it to the eNB.

In S403, the eNB obtains resource scheduling information of the UE by analyzing the above message.

At S430, the eNB may perform resource scheduling on the UE according to the resource scheduling information of the UE, for example, make the number of HARQ processes allocated to the UE less than or equal to the maximum number of HARQ processes, and/or bear the downlink control channel on the For the subframe corresponding to the subframe information, the UE monitors the downlink control channel only in the subframe corresponding to the subframe information.

Optionally, at S404, the eNB may also save the resource scheduling information according to the user identity of the UE.

At S405, when requesting the eNB to perform resource scheduling, the UE or the EPC may send to the eNB, for example, a Resource Request carrying a user identifier.

In S406, the eNB finds out the previously saved resource scheduling information of the UE according to the user identifier.

way 2

In S411, the UE determines resource scheduling information (including the maximum number of HARQ processes that the UE can support and/or subframe information used to indicate whether a subframe may bear a downlink control channel).

In S412, the resource scheduling information is carried in the Attach Request that the eNB does not analyze, and the Attach Request is sent to the eNB through, for example, an RRC establishment complete message, and the eNB transparently transmits the Attach Request to the EPC through, for example, an Initial UE message.
