Description

Method, system, device and storage medium for scheduling unlicensed frequency band resources

Technical Field

The invention relates to the technical field of communication, in particular to a method, a system, a device and a storage medium for scheduling unlicensed frequency band resources of a distributed base station system.

Background

With the scarcity of frequency domain resources of the licensed band required for wireless communication, it is natural that communication using frequency domain resources of the unlicensed band becomes a promising solution. In an lte (long Term evolution) system, the 3GPP standardizes an LAA (License Assisted Access) technology. In Release-13, LAA technology is introduced, which requires the use of CA (Carrier Aggregation). The method comprises the steps that one authorized frequency band is used as a main carrier, and at least one unauthorized frequency band is used as an auxiliary carrier. Uplink and downlink communication can be performed in the licensed band, whereas only downlink communication can be performed in the unlicensed band. In Release-14, standardization of the elaa (enhanced laa) technology is done so that uplink communication on unlicensed bands is also supported. The communication service with higher priority is transmitted by using an authorized frequency band, and the communication service with lower priority is transmitted by using an unauthorized frequency band. After the cellular system evolves to NR (new radio), for the network architecture, service scenario and performance requirement of 5G, in addition to using the authorized frequency band as the Anchor frequency band to obtain the use of the Unlicensed frequency band, it is called NSA NR-U (Non standard one NR Unlicensed Non-independent NR Unlicensed frequency band access). NSA NR-U is a continuing evolution of LAA and eLAA based technologies over 5G. Meanwhile, the NR also supports SA NR-U (Standalone NR Unlicensed independent NR Unlicensed band access).

For the resource usage in the unlicensed frequency band, since it is no longer limited by the scheduling of the base station, theoretically any user can enjoy the usage right of the unlicensed frequency band in any communication system. Therefore, a core problem is how to reduce and eliminate interference from different users or different systems, for example, communication under the 5G standard and communication using WiFi need to avoid mutual interference. The classical approach to this problem is to use the LBT mechanism (Listen Before Talk) that requires detecting the idle-busy status of the frequency band that is desired to be used Before communication. If the frequency band is not used and is in an idle state, the frequency band can be used for communication. Otherwise, if the frequency band is used, it is in busy state, and it is not used for communication.

Therefore, how to improve the data access efficiency in the LAA system becomes an urgent problem to be solved.

Fig. 1 shows a schematic diagram of a protocol stack 100 of a physical layer (PHY layer), a medium access indication layer (MAC layer) and a radio resource indication layer (RRC layer) in an access network in a distributed base station system.

First, Radio Resource management, indication, and scheduling are performed by a Radio Resource Control (RRC) protocol. Specifically, the following functions are mainly included: broadcasting of system information; paging information (paging); establishing and releasing RRC (radio Resource control) connection; transmitting NAS (Non-Access Stratum) information including session management, user management, security management, and charging management; transmitting AS (Access stratum) information including radio bearer management, radio channel processing and encryption; transmission of user radio access capability; configuring wireless resources; measurement configuration and reporting; and a movement indication.

Then, an ip (internet Protocol) header of an upper layer is compressed and decompressed through a Packet Data Convergence Protocol (PDCP), and user Data is transmitted and maintained. Meanwhile, encryption and decryption of user data and an indication plane protocol are supported, so that the integrity of the data is guaranteed.

Subsequently, the segmentation and retransmission services are provided to the user through a Radio Link Control (RLC).

Next, the Media Access Control (MAC) defines the way data frames are propagated, physical addressing and logical topology on the medium. For data transmission, the MAC protocol first determines whether data can be transmitted, and if so, the data and indication information are transmitted to the physical layer in a prescribed format. For data reception, the MAC layer removes header information from the received data from the PHY and transmits the data to an upper layer.

Then, a data path is provided for the data side device through a Physical layer Protocol (PHY) to transmit data.

Finally, data is transmitted and received via a radio frequency link (RF chain).

Three units in a distributed base station system: the functional partitioning of BBU (or DU), rHub (or EU), and RU, as a general understanding, is generally believed that BBU (or DU) will implement the processing functions of RRC, PDCP, High RLC (High-RLC), Low RLC (Low-RLC), High MAC (High-MAC), Low MAC (Low-MAC), and High PHY (High-PHY) protocol modules, rHub will implement the processing functions of Low PHY (Low-PHY) protocol modules, and RU will implement the processing functions of Radio Frequency (RF) modules. But this division of functional blocks is not exclusive. For example, rHub can also perform High-PHY and MAC layer protocol processing.

Fig. 2A to fig. 2C respectively show networking topology diagrams of the distributed base station system of the present invention. In particular, the distributed base station system comprises at least one host unit (BBU/DU) configured to be able to perform at least the processing of data in communication and to perform the modulation and demodulation of baseband signals, as an example only one host unit being shown in the figure; at least one extension unit (rHub) connected to the host unit and configured to perform at least forwarding and merging of uplink and downlink data; at least one Remote Unit (RU) coupled to the expansion unit and configured to perform at least reception and transmission of uplink and downlink radio frequency signals; therefore, in the following description of the embodiments of the invention, the remote unit is referred to as a radio frequency signal transceiving equipment. And at least one communication terminal (not shown) configured to communicate directly with the remote unit.

As shown in fig. 2A to fig. 2C in sequence, the structure of the distributed base station system in the embodiment of the present invention may be of the following three types: star distributed systems, chain distributed systems, and hybrid distributed systems. Specifically, as shown in fig. 2A, in a star distributed system, one BBU within the same cell connects one or more rhubs, each of which is connected to one or more RUs, and the rhubs may be interconnected; as shown in fig. 2B, in the chain-type distributed system, one BBU in the same cell is connected to one master rHub, the remaining multiple slave rhubs are communicated with the BBU through the rHub at the previous stage, each rHub is connected to one or more RUs, and the multiple rhubs may or may not have any difference in function (e.g., master rHub and slave rHub); as shown in fig. 2C, in the hybrid distributed system (i.e., combination of the star distributed system and the chain distributed system), one DU in the same cell is respectively connected to two rhubs, one rHub is connected to a third rHub other than the two rhubs, the third rHub is communicated with the DU through a previous-stage rHub, and each rHub is connected to one or more RUs.

The user equipment referred to in the embodiments of the present invention, also referred to as a communication terminal, is a device that provides voice and/or data connectivity to a user, and the communication terminal may be a mobile terminal, such as a mobile phone (or referred to as a "cellular" phone) and a computer having a mobile terminal, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, which exchanges voice and/or data with a radio access network. For example, the terminal device may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like. Common communication terminals include, for example: the mobile terminal includes a mobile phone, a tablet computer, a notebook computer, a handheld computer, a Mobile Internet Device (MID), and a wearable device, such as a smart watch, a smart bracelet, a pedometer, and the like, but the embodiment of the present application is not limited thereto. A communication terminal may communicate with one or more core networks through a Radio Access Network (RAN).

In the prior art, a radio frequency signal transceiver device under a host unit in a distributed base station system performs LBT detection on unauthorized frequency band resources, and reports respective LBT detection results. The LBT detection may be performed for multiple unlicensed frequency band resources under multiple communication systems. At least one radio frequency signal transceiver device reports LBT detection results aiming at unauthorized frequency band resources to an upstream host unit through an upstream extension unit, the host unit collects the LBT detection results reported by at least one subordinate radio frequency signal transceiver device to judge idle busy state information of each authorized frequency band resource under multiple communication modes, and determines whether at least one unauthorized frequency band resource in an idle state exists or not based on the idle busy state information. For example, for a certain frequency band, if the LBT detection results of all the rf signal transceiving equipment are in an idle state (Vacant), the frequency band is in the idle state; if the LBT detection result of at least one radio frequency signal transceiver device is Busy (Busy), the frequency band is Busy. If at least one unauthorized frequency band resource in the idle state exists, preempting the at least one unauthorized frequency band resource in the idle state, for example, the host unit changes the unauthorized frequency band resource corresponding to the channel into a preemptive state (Reserved), and then, the host unit issues the preemption information to the subordinate radio frequency signal transceiver, and the radio frequency signal transceiver will use the resource on the preempted unauthorized frequency band for communication.

Specifically, as shown in fig. 3, a first radio frequency signal transceiver device (shown as RU 1) and a second radio frequency signal transceiver device (shown as RU 2) respectively perform LBT detection for unlicensed frequency bands f1 and f2 in a 4G communication system and for unlicensed frequency band f1 in a 5G communication system, where the LBT detection result of RU1 is that both the unlicensed frequency band f1 in the 4G communication system and the unlicensed frequency band f2 in the 5G communication system are in an idle state, whereas the unlicensed frequency band f2 in the 4G communication system is in a busy state. The LBT detection result of RU2 is that both the unlicensed band f1 in the 4G communication system and the unlicensed band f2 in the 5G communication system are in an idle state, and also the unlicensed band f2 in the 4G communication system is in an idle state. The LBT detection results of RU1 and RU2 are reported to the host unit upstream thereof via the upstream extension unit, and according to the collected LBT detection results, the host unit can determine that the unlicensed frequency band f1 in the 4G communication system and the 5G communication system is in an idle state, and the unlicensed frequency band f2 in the 4G communication system is in a busy state. Therefore, the host unit preempts at least one unlicensed frequency band f1 in an idle state in the unlicensed frequency bands f1 in the 4G communication system and the 5G communication system, and issues preemption information to the subordinate RUs 1 and RU2, and the RU1 and RU2 select the unlicensed frequency band resources in the idle state for communication according to the preemption information issued by the host unit.

In the prior art, all the radio frequency signal transceiving equipment under the same host unit use a collected LBT detection result, and according to the collected LBT detection result, the host unit issues preemption information. As described in the above example, in this case, both RU1 and RU2 can use only the unlicensed frequency band f1 in the 4G communication system and in the 5G communication system. However, according to the LBT detection result of RU2, the unlicensed band f2 in the 4G communication scheme of RU2 is in an idle state. If RU1 and RU2 are physically distributed at a long distance, such as physically isolated or from different areas, buildings or floors, RU1 and RU2 will not interfere with each other even if they use the same unlicensed band resource (e.g., unlicensed band f2 in 4G communication system) for communication; that is, RU2 uses the RU1 upper frequency band without hindering RU1 communications; therefore, in this case, RU2 does not actually need to refer to the LBT detection result on RU 1. However, in the prior art, the RU2 considers the LBT detection result in the RU1, so that the candidate frequency band resources accessible by the RU2 itself are reduced. Therefore, the unauthorized frequency band resources in the entire distributed base station system are wasted, and the access efficiency for the unauthorized frequency band resources is also lowered.

In view of this, the present invention is directed to fully utilize the unlicensed frequency band resource accessible to the radio frequency signal transceiver device in the distributed base station system, and improve the access efficiency of the radio frequency signal transceiver device for the unlicensed frequency band resource. Therefore, it becomes important to research a new method for scheduling unlicensed frequency band resources.

Fig. 4 is a flowchart illustrating a scheduling method for unlicensed frequency band resources of a distributed base station system according to an embodiment of the present invention. The method for scheduling the unlicensed frequency band resource provided by the embodiment of the present invention may be applied to the distributed base station systems shown in fig. 2A to 2C.

Referring to fig. 4, a method for scheduling unlicensed frequency band resources in a distributed base station system according to an embodiment of the present invention includes the following steps:

step S10, obtaining attribute information of at least one radio frequency signal transceiver, and determining an association relation between the at least one radio frequency signal transceiver based on the attribute information;

step S20, processing the LBT detection result of the at least one radio frequency signal transceiver device for the unlicensed frequency band resource according to the association relationship, and scheduling the unlicensed frequency band resource based on the processing result.

The steps S10 to S20 will be specifically described below.

In step S10, attribute information of at least one radio frequency signal transceiver device is acquired, and an association relationship between the at least one radio frequency signal transceiver device is determined based on the attribute information.

In some embodiments, the host unit in the distributed base station system may obtain the attribute information of at least one radio frequency signal transceiver device, and in other embodiments, a part or all of at least one radio frequency signal transceiver device in the distributed base station system may also obtain the attribute information of each radio frequency signal transceiver device as an autonomous radio frequency signal transceiver device from its upstream device or directly from other radio frequency signal transceiver devices. The setting can be specifically performed according to the actual application requirements, and the embodiment of the present invention is not limited herein.

The attribute information includes one or more of: the identification information of each radio frequency signal transceiver device, the physical position information of each radio frequency signal transceiver device, the three-dimensional Euler distance between each radio frequency signal transceiver device and the upstream device, and the radio frequency distance between each radio frequency signal transceiver device and the upstream device.

Optionally, the attribute information may be obtained through preconfigured information, for example, identification information of each radio frequency signal transceiver device or physical location information of each radio frequency signal transceiver device is determined according to network architecture deployment of the distributed base station system; wherein the physical location information of each radio frequency signal transceiving equipment comprises: the three-dimensional coordinates of each rf transceiver device or other relevant information that can be used to determine the location information of each rf transceiver device, such as the area, building, and floor in which the rf transceiver device is located. The three-dimensional Euler distance between each radio frequency signal transceiver device and the upstream device can be determined by three-dimensional coordinate calculation among the host unit, the extension unit and each radio frequency signal transceiver device. The radio frequency distance between each radio frequency signal transceiver and the upstream device can be obtained by measurement performed by the host unit, for example, the host unit receives and detects a power value of a certain signal uploaded by at least one radio frequency signal transceiver, and determines the radio frequency distance between the host unit and the radio frequency signal transceiver based on the detected power value of the certain signal; the radio frequency distance between each radio frequency signal transceiver device and the upstream device may also be measured at its own side by each radio frequency signal transceiver device and directly reported to the host unit, for example, the radio frequency distance between each radio frequency signal transceiver device and the host unit is determined based on the detected power value of a certain signal received and detected at its own side from the host unit.

In step S20, the LBT detection result of the at least one radio frequency signal transceiver device for the unlicensed frequency band resource is processed according to the association relationship, and the unlicensed frequency band resource is scheduled based on the processing result.

After determining the association relationship between the at least one radio frequency signal transceiver device, the LBT detection result of the at least one radio frequency signal transceiver device for the unlicensed frequency band resource may be processed according to the association relationship between the at least one radio frequency signal transceiver device in the distributed base station system, for example, a plurality of radio frequency signal transceiver devices associated with each other are used as a first device set, each radio frequency signal transceiver device located in the first device set needs to share the LBT detection result for the unlicensed frequency band resource, at least one radio frequency signal transceiver device independent from each other is used as a second device set, and each radio frequency signal transceiver device located in the second device set does not need to share the LBT detection result for the unlicensed frequency band resource, and only needs to be processed separately. That is, the LBT detection result of the at least one radio frequency signal transceiver device for the unlicensed frequency band resource is processed according to the association relationship between the at least one radio frequency signal transceiver device, and the LBT detection result of the plurality of radio frequency signal transceiver devices for the unlicensed frequency band resource and the LBT detection result of the at least one radio frequency signal transceiver device for the unlicensed frequency band resource, which are independent of each other, are classified. It should be understood that, at this time, at least one radio frequency signal transceiver device independent from each other may judge idle-busy state information corresponding to each authorized frequency band under multiple communication systems based on its own LBT detection result without referring to LBT detection results of other radio frequency signal transceiver devices, and then determine whether there is at least one unlicensed frequency band resource in an idle state based on the idle-busy state information.

The method for scheduling the unlicensed frequency band resource provided by the embodiment of the invention can realize that:

when processing the LBT detection result of at least one radio frequency signal transceiver device, determining the incidence relation between the at least one radio frequency signal transceiver device based on the acquired attribute information of the at least one radio frequency signal transceiver device, classifying and processing the LBT detection result of the at least one radio frequency signal transceiver device aiming at the non-authorized frequency range resource according to the incidence relation, and scheduling the non-authorized frequency range resource based on the processing result. Therefore, the waste of the unauthorized frequency band resources in the distributed base station system is reduced, and the access efficiency aiming at the unauthorized frequency band resources is improved.

Hereinafter, three exemplary scenarios of the method for scheduling unlicensed frequency band resources will be described in detail according to a method for scheduling unlicensed frequency band resources managed in a centralized manner, a method for scheduling unlicensed frequency band resources managed in a distributed manner, and a method for scheduling unlicensed frequency band resources managed in a hybrid manner.

Scenario one, a method for scheduling a centrally managed unlicensed frequency band resource.

Fig. 5A is a schematic diagram illustrating an operation of a method for scheduling centrally managed unlicensed band resources according to some embodiments of the present invention. Fig. 5B is a schematic diagram illustrating an operation of a method for scheduling centrally managed unlicensed band resources according to further embodiments of the present invention.

As shown in fig. 5A, the host unit of the distributed base station system acquires the attribute information of each radio frequency signal transceiver device from the at least one radio frequency signal transceiver device, and determines whether each radio frequency signal transceiver device needs to share the LBT detection result with other radio frequency signal transceiver devices based on the acquired attribute information corresponding to each radio frequency signal transceiver device. It should be understood that, in some other embodiments of the present invention, the extension unit may further obtain the attribute information of each radio frequency signal transceiver device from the at least one radio frequency signal transceiver device, and the extension unit reports the obtained attribute information corresponding to each radio frequency signal transceiver device to the host unit upstream of the extension unit. Both of the above embodiments are within the spirit of the invention.

Or as shown in fig. 5B, the host unit of the distributed base station system obtains attribute information corresponding to each radio frequency signal transceiver device according to preconfigured information, and determines whether each radio frequency signal transceiver device needs to share an LBT detection result with other radio frequency signal transceiver devices based on the obtained attribute information corresponding to each radio frequency signal transceiver device.

As shown in fig. 5A or 5B, for each rf signal transceiver, if the rf signal transceiver needs to share the LBT detection result with other rf signal transceivers, the rf signal transceiver may be used as a first type of rf signal transceiver, and if the rf signal transceiver does not need to share the LBT detection result with other rf signal transceivers, the rf signal transceiver may be used as a second type of rf signal transceiver.

In addition, the host unit further generates an LBT start instruction based on the acquired attribute information corresponding to each radio frequency signal transceiver device and sends the LBT start instruction to the at least one radio frequency signal transceiver device, so as to trigger the at least one radio frequency signal transceiver device to implement LBT detection. Illustratively, the indication of initiation of LBT includes: a list of devices for performing LBT detection (for example, a list of radio frequency signal transceiver devices to be subjected to LBT detection), a communication scheme corresponding to LBT detection (for example, including a 4G or 5G communication scheme), and unlicensed frequency band information for LBT detection.

The at least one radio frequency signal transceiver device responds to the start instruction of the LBT and triggers to implement LBT detection, and then reports the respective LBT detection result to the host unit upstream thereof, or reports the respective LBT detection result to the extension unit upstream thereof, and then reports the respective LBT detection result to the host unit upstream thereof. Next, the host unit classifies the LBT detection result reported from each rf transceiver device according to the category of each rf transceiver device.

For all the first-class radio frequency signal transceiver devices, the host unit can carry out convergence processing on the LBT detection result of each first-class radio frequency signal transceiver device; for example, for a certain frequency band, if the LBT detection results of all the first type radio frequency signal transceiver devices are in an idle state, the frequency band is in the idle state; if the LBT detection result of at least one first type radio frequency signal transceiver device is busy, the frequency band is busy. Then, the host unit of the upstream device schedules the unlicensed frequency band resource according to the idle-busy state information of each unlicensed frequency band resource in the aggregation result.

For each second type of radio frequency signal transceiver, the host unit directly receives the LBT detection result reported by the second type of radio frequency signal transceiver, and does not perform convergence operation any more, but performs processing alone according to the LBT detection result of the second type of radio frequency signal transceiver. For example, for a certain frequency band, if the LBT detection result of the second type of radio frequency signal transceiver device is in an idle state, the frequency band is in the idle state; and if the LBT detection result of the second type of radio frequency signal transceiving equipment is in a busy state, the frequency band is in the busy state. Then, the host unit schedules the unlicensed frequency band resource according to the idle busy status of each unlicensed frequency band resource in the result after the individual processing.

If at least one unauthorized frequency band resource in an idle state exists currently, the host unit preempts one of the at least one unauthorized frequency band resource in the idle state, for example, the host unit preempts at least one of the channels in the idle state to change the channel into the preempt state, performs resource scheduling on the unauthorized frequency band, and sends information (resource scheduling information) of the preempted unauthorized frequency band resource to all the radio frequency signal transceiver devices for subsequent use by the radio frequency signal transceiver devices; if the unlicensed frequency band resource in the idle state does not exist currently, the host unit regenerates an LBT start instruction, and sends the LBT start instruction to the at least one radio frequency signal transceiver device to trigger the at least one radio frequency signal transceiver device to continue to implement LBT detection.

It should be noted that, in some other embodiments of the present invention, a group of radio frequency signal transceiver devices having a predetermined group attribute may be used as a subset of the clustering devices.

For example, all the first-type radio frequency signal transceiving devices are taken as a first RU set, and all the second-type radio frequency signal transceiving devices are taken as a second RU set. The first set of RUs may also have a plurality of subsets, e.g., the first set of RUs includes M RUs, e.g.: RU (RU)₁、RU₂……RU_m(M =1,2 … … M), wherein, RU_m(m =1,2 … … k) is to be treated as a subset of one RU, whose LBT detection results are to be processed collectively; wherein, RU_m(M = k +1, k +2 … … M) will be treated as a subset of another RU, whose LBT detection results will be processed collectively. When the host unit generates and transmits the LBT initiation instruction, all the radio frequency signal transceiver devices may be instructed to perform the LBT detection, or some of the radio frequency signal transceiver devices may be instructed to perform the LBT detection. That is, all the first-class rf signal transceivers only need to share the LBT detection result with other first-class rf signal transceivers belonging to the same cluster; without the need to share the LBT detection result with other first type radio frequency signal transceiving devices that do not belong to the same cluster as themselves, and with all second type radio frequency signal transceiving devices.

In order to reduce the burden of the radio frequency signal transceiver device to perform LBT detection, for each subset of clustering devices, only any one of the radio frequency signal transceiver devices in the subset of clustering devices may be selected as an object to perform LBT detection, and an LBT detection result of the object may be used as an LBT detection result of the subset of clustering devices. For example, the host unit may determine that a plurality of radio frequency signal transceiving devices are located at positions close to each other according to the attribute information of at least one corresponding radio frequency signal transceiving device, or determine that the same user terminal may simultaneously access a plurality of radio frequency signal transceiving devices. Therefore, the LBT detection results of the plurality of radio frequency signal transceiver devices located at close distances can be considered as consistent, and the plurality of radio frequency signal transceiver devices can be considered as a subset of clustering devices; or the LBT detection results of the plurality of radio frequency signal transceiving devices accessed by the same user terminal may be considered to be consistent, and the plurality of radio frequency signal transceiving devices may also be considered as a subset of clustering devices. At this time, when the host unit generates and transmits an LBT initiation indication, based on each cluster device subset that has been determined, any one of the radio frequency signal transceiver devices under the cluster device subset may be selected as an object for performing LBT detection, and an LBT detection result of the object may be used as an LBT detection result of the cluster device subset. Then, for the LBT detection result of the cluster device subset, the host unit selects and reserves at least one unlicensed frequency band in an idle state, and issues reservation information to all the radio frequency signal transceiving devices in the cluster device subset. When the reservation information of the unlicensed frequency band is occupied, it indicates that the host unit occupies the corresponding unlicensed frequency band for the radio frequency signal transceiver device, and the communication resource on the unlicensed frequency band can be scheduled for use. And when the reservation information of the unauthorized frequency band is not occupied, the host unit indicates that the host unit does not preempt the corresponding unauthorized frequency band for the radio frequency signal transceiver, and the communication resource on the unauthorized frequency band cannot be scheduled for use. Fig. 5C is a schematic diagram illustrating an operation of processing the LBT detection result of the radio frequency signal transceiver device according to the centrally managed unlicensed frequency band resource scheduling of fig. 5A and 5B.

As shown in fig. 5A-5C, for example, taking the LBT detection results of three radio frequency signal transceiver devices as an example, the detection results of LBT of each radio frequency signal transceiver device are shown in table 1 below:

the host unit may determine, for example, that the RU1 and the RU2 need to perform the aggregation of the LBT detection results, and the LBT result of the RU3 does not need to perform the aggregation of the LBT detection results, according to the preconfigured information and the identification information of each radio frequency signal transceiving device.

When the host unit receives the above-mentioned LBT detection results of the three RUs, the LBT results of RU1 and RU2 are summarized. The processing result of LBT processed by the host unit according to the association relationship of the three RUs is shown in table 2 below:

and then, the host unit reserves each unauthorized frequency band according to the idle busy state information of each unauthorized frequency band, indicates that the resources of the unauthorized frequency band can be used, and sends the preemption information to at least one RU. The non-authorized frequency band preemption information under each communication system is shown in the following table 3:

and a second scenario is a distributed management method for scheduling the unauthorized frequency band resources.

Fig. 6A is a schematic operation flow diagram of a scheduling method for distributed management of unlicensed frequency band resources according to some embodiments of the present invention, and fig. 7 is a schematic operation flow diagram of a scheduling method for distributed management of unlicensed frequency band resources according to another embodiment of the present invention.

As shown in fig. 6A and 7, a part or all of at least one radio frequency signal transceiving device of the distributed base station system, as an autonomous radio frequency signal transceiving device, respectively obtains attribute information of each radio frequency signal transceiving device from an upstream device (e.g., a host unit or an extension unit) thereof, and determines whether it needs to share an LBT detection result with other radio frequency signal transceiving devices based on the obtained attribute information of the corresponding other radio frequency signal transceiving devices. For each other radio frequency signal transceiver device, if the radio frequency signal transceiver device needs to share the LBT detection result with the radio frequency signal transceiver device, the radio frequency signal transceiver device is used as a first class of radio frequency signal transceiver device, and if the radio frequency signal transceiver device does not need to share the LBT detection result with the radio frequency signal transceiver device, the radio frequency signal transceiver device is used as a second class of radio frequency signal transceiver device.

Optionally, in some embodiments of the present invention, the host unit or the extension unit of the distributed base station system may further carry LBT initiation indication information while sending the attribute information of at least one radio frequency signal transceiver device to each radio frequency signal transceiver device, that is, select a radio frequency signal transceiver device indicating a part of the LBT initiation indication information as an object for implementing LBT detection. And each radio frequency signal transceiver device triggers the implementation of the LBT detection after matching the LBT starting indication information, and judges whether the radio frequency signal transceiver device needs to share the LBT detection result with other radio frequency signal transceiver devices or not based on the acquired attribute information corresponding to other radio frequency signal transceiver devices. If the LBT detection result needs to be shared with other radio frequency signal transceiving equipment, the LBT detection result of the host computer is reported to the host computer unit at the upstream, or the LBT detection result is reported to the expansion unit at the upstream first and then is reported to the host computer unit at the upstream by the expansion unit.

Optionally, in some other embodiments of the present invention, when the host unit or the extension unit of the distributed base station system only transmits the attribute information of the at least one radio frequency signal transceiver device to each radio frequency signal transceiver device, that is, the autonomous radio frequency signal transceiver device does not receive the LBT start indication from the host unit or the extension unit, in this case, all of the at least one radio frequency signal transceiver device may be used as the autonomous radio frequency signal transceiver device to perform LBT detection based on a default rule; it is also possible to alternate in time to communicate with other radio frequency signal transceiving devices to determine whether LBT detection needs to be performed based on predetermined rules, for example.

For each autonomous radio frequency signal transceiver, if the autonomous radio frequency signal transceiver needs to share the LBT detection result with other radio frequency signal transceivers, the autonomous radio frequency signal transceiver aggregates the LBT detection result of the autonomous radio frequency signal transceiver with the received LBT detection results of all radio frequency signal transceivers belonging to the same cluster. Specifically, the host unit receives LBT detection results reported from all the first type of radio frequency signal transceiver devices, and then forwards LBT detection results of other radio frequency signal transceiver devices belonging to the same cluster as the autonomous radio frequency signal transceiver device to the autonomous radio frequency signal transceiver device. And then the autonomous radio frequency signal transceiver judges whether an idle unauthorized frequency band exists according to the LBT detection result of the autonomous radio frequency signal transceiver and the LBT detection result of the radio frequency signal transceiver which belongs to the same cluster with the autonomous radio frequency signal transceiver and is forwarded by the host unit. If the autonomous radio frequency signal transceiver does not need to share the LBT detection result with any other radio frequency signal transceiver, the autonomous radio frequency signal transceiver only processes the LBT detection result of the autonomous radio frequency signal transceiver, and does not need to report the LBT detection result of the autonomous radio frequency signal transceiver to the host unit. And then the autonomous radio frequency signal transceiver judges whether an idle unauthorized frequency band exists according to the LBT detection result of the autonomous radio frequency signal transceiver. The radio frequency signal transceiver devices that need to share the LBT detection result with each other belong to the same cluster.

In fig. 6A, for each autonomous radio frequency signal transceiver device, if the autonomous radio frequency signal transceiver device belongs to a first class of radio frequency signal transceiver devices, that is, the autonomous radio frequency signal transceiver device needs to share an LBT detection result with other radio frequency signal transceiver devices, all the unlicensed frequency band resource lists in the aggregation result in an idle state are sent to the upstream device thereof, so that the upstream device schedules the unlicensed frequency band resources. If the autonomous radio frequency signal transceiver device belongs to a second class of radio frequency signal transceiver devices, that is, the LBT detection result does not need to be shared with other radio frequency signal transceiver devices, all the unauthorized frequency band resource lists in the idle state in the separately processed result are sent to the upstream device thereof so that the upstream device can schedule the unauthorized frequency band resources. And if at least one unlicensed frequency band resource in an idle state exists currently, preempting one of the at least one unlicensed frequency band resource in the idle state for subsequent use.

In fig. 7, different from fig. 6A, in this embodiment, for each autonomous radio frequency signal transceiver, if the autonomous radio frequency signal transceiver belongs to a first class of radio frequency signal transceiver, that is, it needs to share an LBT detection result with other radio frequency signal transceivers, the autonomous radio frequency signal transceiver schedules the unlicensed frequency band resource according to a busy state of each unlicensed frequency band resource in the aggregation result, and if the autonomous radio frequency signal transceiver belongs to a second class of radio frequency signal transceiver, that is, it does not need to share an LBT detection result with other radio frequency signal transceivers, the autonomous radio frequency signal transceiver schedules the unlicensed frequency band resource according to a busy state of each unlicensed frequency band resource in the result after being processed separately. In fig. 7, for a certain frequency band, because the individual processing of the LBT detection results of all the second class of rf signal transceivers is completed at the rf signal transceiver side, for each class of rf signal transceivers belonging to the second class of rf signal transceivers, since the LBT detection result of the class of rf signal transceivers is consistent with the finally received preemption information result, it can be determined which unauthorized frequency bands can be preempted by the LBT result of the class of rf signal transceivers belonging to the second class of rf signal transceivers, so that it is not necessary to report the determination result of whether there is an idle frequency band to the host unit first, and then wait for the information of the preempted unauthorized frequency band resources issued by the host unit, and the process of reporting the determination result of whether there is an idle frequency band and then waiting for receiving the preemption information increases the time for channel access, and increases the processing load of the host unit. Therefore, the resource scheduling of the unauthorized frequency band is executed by each autonomous radio frequency signal transceiver, which not only can reduce the time for channel access and improve the access efficiency of the distributed base station system for the unauthorized frequency band resource, but also can reduce the processing burden of the host unit.

In addition, in fig. 7, for a certain frequency band, since the aggregation processing of the LBT detection results of all the first-class rf signal transceivers is completed on the rf signal transceiver side, that is, the idle-busy state information corresponding to all the first-class rf signal transceivers can be obtained on the rf signal transceiver side, if there is at least one idle unlicensed frequency band resource, the at least one idle unlicensed frequency band resource is preempted, compared with the implementation in fig. 6A, on one hand, since the host unit does not need to perform resource scheduling according to the idle-busy state of the reported frequency band, the load reduction of the host unit is achieved, and on the other hand, since the idle-busy state information obtained by the aggregation processing on the rf signal transceiver side is consistent with the finally received preemption information result issued by the host unit, the resource scheduling can be carried out on the radio frequency signal transceiver side, so that the process of reporting the LBT detection result and waiting for receiving the preemption information is reduced, and the access efficiency of the distributed base station system for the unauthorized frequency band resource can be improved.

As shown in fig. 6A-6B, for example, taking LBT detection results of three radio frequency signal transceiver devices as an example, each radio frequency signal transceiver device reports its own LBT detection result to the host unit, the host unit forwards the received LBT detection result to other radio frequency signal transceiver devices, and each radio frequency signal transceiver device receives LBT detection results of other radio frequency signal transceiver devices except for itself. For example, the host unit sends the LBT detection results of RU2 and RU3 to RU1, sends the LBT results of RU1 and RU3 to RU2, and sends the LBT results of RU1 and RU2 to RU 3. The LBT results received at each RU are as shown in table 4 below:

each radio frequency signal transceiver device determines the association relationship between itself and other radio frequency signal transceiver devices based on the acquired at least one radio frequency signal transceiver device attribute information, determines whether itself needs to share the LBT detection result with other radio frequency signal transceiver devices according to the association relationship, so as to determine whether the LBT detection result of itself needs to be aggregated with the LBT detection result of other radio frequency signal transceiver devices, and the final LBT aggregation processing result obtained after aggregation processing is shown in table 5 below.

It should be noted that, in table 5, it is determined whether it is necessary to perform aggregation processing on the LBT detection result of the RU and the LBT detection results of other RUs for each RU, if "yes", it indicates that the final LBT summary result of the RU needs to include the LBT detection result of the RU, and if "no", it indicates that the most LBT summary result of the RU does not need to include the LBT detection result of the RU. Illustratively, for RU1, the final LBT summary result of RU1 includes the LBT detection results of RU1 and RU2, for RU2, the final LBT summary result of RU2 includes the LBT detection results of RU1 and RU2, and for RU3, the final LBT summary result of RU3 includes only the detection result of RU 3.

And a third scenario is the scheduling method of hybrid management of the unauthorized frequency band resource.

Fig. 8A is a schematic operational flow diagram illustrating a scheduling method for hybrid-managed unlicensed band resources according to some embodiments of the present invention, fig. 8B is a schematic operational flow diagram illustrating a scheduling method for hybrid-managed unlicensed band resources according to some embodiments of the present invention, fig. 9A is a schematic operational flow diagram illustrating a scheduling method for hybrid-managed unlicensed band resources according to some other embodiments of the present invention, and fig. 9B is a schematic operational flow diagram illustrating a scheduling method for hybrid-managed unlicensed band resources according to some other embodiments of the present invention.

As shown in fig. 8A, 8B, 9A, and 9B, similar to fig. 5A and 5B, the host unit of the distributed base station system acquires the attribute information of each rf signal transceiver device from the at least one rf signal transceiver device, or the host unit of the distributed base station system acquires the attribute information corresponding to each rf signal transceiver device according to preconfigured information, and determines whether each rf signal transceiver device needs to share the LBT detection result with other rf signal transceiver devices based on the acquired attribute information corresponding to each rf signal transceiver device. Subsequently, the host unit transmits the sharing requirement information of the LBT detection result to each rf signal transceiving equipment.

For each radio frequency signal transceiver device, if the radio frequency signal transceiver device needs to share the LBT detection result with other radio frequency signal transceiver devices, the radio frequency signal transceiver device is used as a first class of radio frequency signal transceiver device, and if the radio frequency signal transceiver device does not need to share the LBT detection result with other radio frequency signal transceiver devices, the radio frequency signal transceiver device is used as a second class of radio frequency signal transceiver device.

For each radio frequency signal transceiver, if the radio frequency signal transceiver needs to share the LBT detection result with other radio frequency signal transceivers, the radio frequency signal transceiver aggregates the LBT detection result of the radio frequency signal transceiver with the received LBT detection results of all the first class radio frequency signal transceivers belonging to the same cluster as the radio frequency signal transceiver. Specifically, the host unit receives LBT detection results reported from all the first type of radio frequency signal transceiver devices, and then forwards LBT detection results of other radio frequency signal transceiver devices belonging to the same cluster as the radio frequency signal transceiver device to the radio frequency signal transceiver device. And then the radio frequency signal transceiver judges whether an idle unauthorized frequency band exists according to the LBT detection result of the radio frequency signal transceiver and the LBT detection result of the radio frequency signal transceiver which belongs to the same cluster with the radio frequency signal transceiver and is forwarded by the host unit. If the radio frequency signal transceiver does not need to share the LBT detection result with any other radio frequency signal transceiver, the radio frequency signal transceiver only processes the LBT detection result of the radio frequency signal transceiver alone, and does not need to report the LBT detection result of the radio frequency signal transceiver to the host unit. And then the radio frequency signal transceiver equipment judges whether an idle unauthorized frequency band exists according to the LBT detection result of the radio frequency signal transceiver equipment.

In fig. 8A, for each rf signal transceiver device, if the rf signal transceiver device belongs to a first class of rf signal transceiver devices, that is, the rf signal transceiver device needs to share an LBT detection result with other rf signal transceiver devices, all the unlicensed frequency band resource lists in an idle state in the aggregation result are sent to the upstream device thereof, so that the upstream device schedules the unlicensed frequency band resource. If the radio frequency signal transceiver device belongs to a second class of radio frequency signal transceiver devices, that is, the LBT detection result does not need to be shared with other radio frequency signal transceiver devices, all the unauthorized frequency band resource lists in the idle state in the separately processed result are sent to the upstream device thereof so that the upstream device can schedule the unauthorized frequency band resources.

In fig. 9A and 9B, different from fig. 8A and 8B, in this embodiment, for each radio frequency signal transceiver device, if the radio frequency signal transceiver device belongs to a first type of radio frequency signal transceiver device, that is, it needs to share an LBT detection result with other radio frequency signal transceiver devices, the radio frequency signal transceiver device schedules the unlicensed frequency band resource according to an idle-busy state of each unlicensed frequency band resource in the aggregation result, and if the radio frequency signal transceiver device belongs to a second type of radio frequency signal transceiver device, that is, it does not need to share an LBT detection result with other radio frequency signal transceiver devices, the radio frequency signal transceiver device schedules the unlicensed frequency band resource according to an idle-busy state of each unlicensed frequency band resource in the result after being processed separately. In fig. 9A, for a certain frequency band, because the individual processing of the LBT detection results of all the second class of radio frequency signal transceivers is completed on the side of the radio frequency signal transceiver, for each class of radio frequency signal transceiver belonging to the second class of radio frequency signal transceiver, since the LBT detection result of the class of radio frequency signal transceiver is consistent with the result of the finally received preemption information, it can be determined which unauthorized frequency bands can be preempted by the LBT result of the class of radio frequency signal transceiver belonging to the second class of radio frequency signal transceiver, so that it is not necessary to report the determination result of whether there is an idle frequency band to the host unit first, and then wait for the information of the preempted unauthorized frequency band resources issued by the host unit, and the process of reporting the determination result of whether there is an idle frequency band and then waiting for receiving the preemption information increases the time for channel access, and increases the processing load of the host unit. Therefore, the resource scheduling of the unauthorized frequency band is executed by each autonomous radio frequency signal transceiver, which not only can reduce the time for channel access and improve the access efficiency of the distributed base station system for the unauthorized frequency band resource, but also can reduce the processing burden of the host unit. Fig. 8C is a schematic diagram illustrating an operation of processing LBT detection results of the radio frequency signal transceiver device according to the hybrid management unlicensed frequency band resource scheduling of fig. 8A and 8B.

As shown in fig. 8A, 8B, and 8C, for example, taking the LBT detection results of three radio frequency signal transceiver devices as an example, after performing the LBT detection, each radio frequency signal transceiver device determines whether it needs to share the LBT detection result with other radio frequency signal transceiver devices, and RU3 determines that it does not need to share the LBT detection result with other RUs. RU1 and RU2 report the LBT detection result to the host unit, whereas RU3 does not report the LBT detection result to the host unit. When the host unit receives the reported LBT detection result, the host unit sends the LBT detection result of RU2 to RU1, and sends the LBT detection result of RU1 to RU 2.

RU1 and RU2 receive LBT detection results except for the LBT detection results of themselves, then carry out convergence processing on the LBT detection results of themselves, and then judge the idle-busy state of at least one unlicensed frequency band based on the processing results after the convergence processing.

As shown in fig. 8A, 8B, and 8D, for example, taking the LBT detection results of four radio frequency signal transceiver devices as an example, after performing the LBT detection, each radio frequency signal transceiver device determines whether it needs to share the LBT detection result with other radio frequency signal transceiver devices, and RU4 determines that it does not need to share the LBT detection result with other RUs. RU1, RU2 and RU3 therefore report their respective LBT detection results to the host unit, whereas RU4 does not report LBT detection results to the host unit.

After receiving the LBT detection results of all RUs that need to share the LBT detection result, the host unit performs primary LBT detection result aggregation to reduce the number of delivered LBT detection results. Specifically, the host unit transmits the LBT convergence results of RU2 and RU3 to RU1, transmits the LBT convergence results of RU1 and RU3 to RU2, and transmits the LBT convergence results of RU1 and RU2 to RU 3. The RUs 1, RU2 and RU3 receive the LBT result after the convergence processing of the other RUs except the RUs themselves, then perform convergence processing with the LBT detection result of the RUs themselves, and then judge the idle-busy state of at least one unlicensed frequency band based on the processing result after the convergence processing.

According to another aspect of the present invention, an embodiment of the present invention provides a scheduling system for unlicensed frequency band resources of a distributed base station.

As shown in fig. 10, the system 200 for scheduling unlicensed frequency band resources includes: a relationship determination node 210, configured to obtain attribute information of at least one radio frequency signal transceiver, and determine an association relationship between the at least one radio frequency signal transceiver based on the attribute information; a data processing node 220, configured to process, according to the association relationship, an LBT detection result of the at least one radio frequency signal transceiver device for an unlicensed frequency band resource; and scheduling the unlicensed frequency band resource based on the processing result.

The specific functions of each node and unit in the system 200 for scheduling unlicensed frequency band resources for a distributed base station according to the present invention will be described in detail below with reference to fig. 4 to 9.

A relationship decision node 210 in the unlicensed frequency band resource scheduling system 200 receives attribute information of at least one radio frequency transceiver device, and determines an association relationship between the at least one radio frequency transceiver device based on the attribute information; illustratively, the attribute information includes one or more of the following: the identification information of each radio frequency signal transceiver device, the physical position information of each radio frequency signal transceiver device, the three-dimensional Euler distance between each radio frequency signal transceiver device and the upstream device, and the radio frequency distance between each radio frequency signal transceiver device and the upstream device.
