Description

Discontinuous reception method and related device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a discontinuous reception method and a related apparatus.

Background

With the development of wireless communication systems, terminal types and service types are diversified, the requirements of wireless communication are diversified, different service scenes emphasize different requirements, for example, a low-delay high-reliability scene (URLLC) emphasizes the requirement on data transmission delay reliability, large-scale machine type communication (eMTC) emphasizes the requirement on terminal data bulkiness and terminal power saving, and enhanced broadband mobile communication (eMBB) emphasizes the requirement on high data rate and system capacity. Aiming at diversified requirements, a new challenge is provided for the power saving design of the terminal.

In the prior art, a terminal employs a Discontinuous Reception (DRX) mechanism to achieve power saving. During the discontinuous reception period, the terminal discontinuously receives the data signal. And at the moment that the DRX does not receive the data signal, the terminal enters an inactive state, specifically, the radio frequency and the baseband processor are closed, and the like, so that the standby time of the battery and the service life of the battery are prolonged.

In the LTE system, the UE may have two states, namely, a continuous reception state and a DRX (Radio Resource Control) state in an RRC (Radio Resource Control) connected state. While the relevant configuration of the DRX mechanism in the LTE system is only for the terminal side, i.e. the terminal side is provided with a DRX cycle and a series of timers.

At the beginning of each DRX cycle, the terminal enters a short continuous reception state called On Duration (listening period), and the Duration of the On Duration is counted by an On Duration Timer in the above-mentioned series of timers. The OnDuration Timer is defined as: several consecutive subframes that can carry a PDCCH (physical downlink Control Channel) counted from the beginning of the DRX cycle. During this period, the UE needs to monitor the PDCCH to see if there is a resource allocation for the UE. If the terminal receives downlink scheduling and downlink data during the on duration, other timers are started to carry out the subsequent scheduling process, but if the terminal does not receive the downlink scheduling and the downlink data during the on duration, the terminal enters an inactive state, and the inactive state is maintained until the current DRX period is finished. The On Duration Timer can start to re-receive downlink transmission at the next DRX cycle.

If the UE receives the scheduling command and downlink transmission during the on duration, the following timer may also be started to instruct the UE to further monitor the PDCCH.

DRX Inactivity Timer (Inactivity Timer for DRX): starting when the PDCCH for scheduling new data is received, and monitoring the PDCCH by the UE during the starting period; the termination condition is that the timer times out or that a MAC layer signaling is received that forces a termination.

HARQ RTT Timer (HARQ Round Trip Time Timer): for downlink transmission. The method is started when the PDCCH for scheduling downlink data is received, the fixed length is a retransmission time interval, and the PDCCH does not need to be monitored unless being covered by other timers in the period.

DRX Retransmission Timer (DRX Retransmission Timer): for downlink transmission. Starting the HARQ RTT Timer after the time out, wherein the UE monitors the PDCCH all the time during the starting period; the termination condition is that the timer has expired or that an expected retransmission schedule has been received.

Contention Resolution Timer (Contention Resolution Timer): a timer in the random access procedure. Starting from uplink transmission scheduled by a random access response in a random access process sent by UE, wherein the UE monitors a PDCCH all the time during the starting period; the termination condition is that the timer times out or that a contention resolution message is successfully received.

It can be seen that the existing DRX configuration mechanism needs to introduce a large number of timers on the terminal side, which not only increases the complexity of scheme implementation, but also obviously, the timer valid timing period is fixed in the whole DRX cycle, and thus has no flexibility. As mentioned above, for the On Duration Timer, during the On Duration Timer period, if the terminal does not receive the scheduling command and downlink transmission, it enters the inactive state and turns off the rf and baseband processor. However, during the On Duration Timer period, the terminal does not receive the scheduling command and downlink transmission, which does not mean that the terminal does not have a new scheduling command and downlink transmission in the period of the inactive state, and particularly, when the terminal has a data transmission task with a high delay requirement during the inactive state, the terminal can only transmit the data at the next On Duration Timer period (i.e., after the current DRX cycle is ended).

At present, with the application of a 5G network, the service types are more diversified, and obviously, the existing DRX execution mechanism cannot meet the multi-level requirements of the wireless communication network.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The related configuration of the discontinuous reception at the terminal side is fixed, that is, the terminal side needs to refer to a large number of timers in the process of executing the discontinuous reception, so that not only is the execution mechanism relatively complex, but also the adaptive flexible change cannot be performed according to the actual requirements, and the multi-level requirements on the wireless communication network cannot be met. In view of the above, the present invention provides a solution.

In one aspect, the present invention provides a discontinuous reception method, where the application scenario includes a network side device and a terminal.

The network side device may be, but not limited to, a Base Station (eNB), which may be in any form, and may be a Macro Base Station (Macro Base Station), a micro Base Station (Pico Base Station), a Node B (3G mobile Station), an enhanced Base Station (eNB), a Home enhanced Base Station (Femto eNB or Home eNode or Home eNB or HeNB), a relay Station, an access point, an RRU (Remote Radio Unit, Remote Radio module), an RRH (Remote Radio Head ), and the like. In addition, with the development of 5G technology, base stations may be replaced with other functional nodes, such as Central Units (CUs) and Distributed Units (DUs). The terminal may be, but is not limited to, a mobile terminal device on the user side, such as a mobile phone, a PAD, etc.

Referring to fig. 1, the method of discontinuous reception of the present invention includes, at a terminal side:

step 11, a terminal receives a discontinuous reception command sent by a network side device and acquires configuration information for executing discontinuous reception from the discontinuous reception command, wherein the configuration information is determined by the network side device when the terminal needs to be controlled to execute discontinuous reception;

and step 12, the terminal executes discontinuous reception within the determined effective time based on the configuration information.

Correspondingly, referring to fig. 2, the method for discontinuous reception according to the present invention includes, at a network side device:

step 21, when the network side equipment needs to control the terminal to execute discontinuous reception, determining configuration information required by the terminal to execute discontinuous reception;

step 22, the network side device sends the configuration information to the terminal through the discontinuous reception command, so that the terminal executes discontinuous reception within the determined effective time based on the configuration information.

Obviously, the method of the present invention dynamically sets the configuration information required by discontinuous reception on the network side, and compared with the prior art, the network side can flexibly configure the relevant parameters of the discontinuous reception of the terminal in a dynamic mode according to the multi-level requirements of the service, so that the terminal determines when to enter the inactive state and when to enter the active state within the determined effective time according to the configuration information of the network side, thereby achieving more reasonable and effective power saving effect.

The method of the present invention is described below by way of example.

And after receiving the discontinuous reception command, the terminal counts the effective time, namely the period of discontinuous reception begins.

Under normal conditions, the terminal continues to finish the ongoing data transmission after receiving the discontinuous receiving command, and enters an inactive state after the data transmission is finished until the end time of the effective time.

In some special cases, for example, in an inactive state within the effective time, if it is necessary to transmit a specific service and/or initiate a specific transmission action, the terminal enters an active state, completes transmission of the specific service and/or initiates the specific transmission action, and after the specific service and/or initiates the specific transmission action is completed, if the end time of the effective time is not reached, the terminal enters the inactive state again.

Obviously, in order to implement the above scheme, when the method of the present invention is applied to a network side device, the network side device determines the specific service and the specific transmission action according to actual requirements, and uses them as configuration information of discontinuous reception to inform a terminal.

Correspondingly, in the method applied to the discontinuous reception of the terminal, after the terminal acquires the configuration information sent by the network side device, the terminal determines the specific service and the specific transmission action from the configuration information, and executes the discontinuous reception according to the execution mode corresponding to the special condition.

By way of exemplary introduction, the specific service may be a service that does not support discontinuous reception, which is referred to herein as a first service, and the first service may be a service that has a high delay requirement, and obviously the first service is not applicable to discontinuous reception.

The network side device may send the indication information of the first service that does not support discontinuous reception to the terminal as the configuration information.

The terminal can determine the first service based on the configuration information, continues to complete ongoing data transmission after receiving the discontinuous receiving command, enters an inactive state after the data transmission is finished if no data transmission task of the first service exists currently, enters an active state to execute the data transmission task of the first service if the data transmission task of the first service is obtained in the inactive state within the effective time, and re-enters the inactive state if the end time of the effective time is not reached after the data transmission task of the first service is finished.

In practical application, different RB, RB group, logical channel LC, logical channel group, LCG, and network slice correspond to different delay requirements, so the network side device of the present invention can classify services according to one or more of RB, RBG, LC, LCG, and slice.

Obviously, the RB, RBG, LC, LCG, slice with higher requirement for delay may be the first service.

In order to save the overhead of configuration information, the network side device may use the ID of the RB, the ID of the RBG, the ID of the LC, the ID of the LCG, and the ID of the slice with higher delay requirement as the indication information of the first service, such as RB-1, RB-3, and slice-4.

Correspondingly, after receiving the configuration information, the terminal side can determine that the tasks under RB-1, RB-3 and slice-4 are the first tasks.

In addition, the specific transmission action may be an action of uplink scheduling initiated by the terminal and/or initiating monitoring of a downlink paging message, and may be, but is not limited to, a calling action, a called action, and the like in practical applications, and obviously, such a transmission action is not applicable to discontinuous reception.

The network side device may send the indication information of the specific transmission action as configuration information to the terminal.

The terminal may determine a specific transmission action based on the configuration information, and in an inactive state within the effective time, if a specific transmission action (such as an uplink scheduling action, a downlink paging message monitoring action, a downlink broadcast message monitoring action, and the like) needs to be initiated, enter an active state to initiate the specific transmission action, and after the specific transmission action is completed, if the end time of the effective time is not reached, enter the inactive state again.

In addition, on the basis or as another implementation manner, the network side device may also determine that a service (referred to as a second service herein) supporting discontinuous reception is supported, and notify the terminal of the second service through the configuration information, and the terminal may enter an inactive state when only a data transmission task of the second service is currently left.

Similarly, as an implementation manner, the tasks under the RB, RBG, LC, LCG, and slice with lower delay requirements may be used as the second service. The configuration information of the network side device may use IDs of RBs, RBGs, LCs, LCGs, and slices corresponding to the second service as the indication information of the second service.

Further, to reduce the overhead of the discontinuous reception command, on the basis, when the network side device needs to control the terminal to perform discontinuous reception, if it is determined that the configuration information required by the terminal to perform discontinuous reception is consistent with the configuration information for performing discontinuous reception last time, the network side device may send the discontinuous reception command carrying a restart instruction to the terminal device, where the start instruction replaces the configuration information, and therefore the overhead is smaller than the overhead of the configuration information.

On the terminal side, if a re-instruction is obtained from the received discontinuous reception command, the default edge executes the discontinuous reception with the configuration information of the last discontinuous reception execution.

In addition, in the method of the present invention, the network side device may only determine a part of configuration information required by the terminal to perform discontinuous reception, and the other part of configuration information may be pre-stored by the terminal, or determined by the terminal based on a preset protocol and/or a preset priority algorithm, etc.

The following describes an exemplary application of the discontinuous reception method of the present invention in conjunction with several embodiments.

Example one

The network side equipment configures an optional discontinuous reception parameter set for the terminal, and indicates the configuration parameters of discontinuous reception in an index mode in a discontinuous reception command.

The discontinuous reception parameter set comprises one or more of:

time configuration of discontinuous reception: the time length of the discontinuous reception performed by the terminal may be, and in practical applications, the index number may be used in the configuration information to indicate different time lengths.

The applicable service types are as follows: in this embodiment, the services may be classified according to radio bearers RB, radio bearer group RBG, logical channels LC, logical channel group LCG, and network slice. Services under different RBs, RBGs, LCGs and slices have different requirements on delay, and discontinuous reception can be performed on the services under the RBs, RBGs, LCGs and slices with lower requirements on delay. Specifically, the configuration information is indicated by ID numbers of RB, RBG, LC, LCG, and slice, for example, if RB1 appears in an applicable service type in the configuration information, it indicates that the task under RB1 can perform discontinuous reception.

Whether exception items (indicating the specific transfer actions described above) are allowed: for example, whether to initiate an uplink transmission action during discontinuous reception or initiate a downlink reception action.

The network side executing step of the first embodiment includes:

the method comprises the following steps: the network side device configures a discontinuous reception parameter set (configuration information required by the terminal to perform discontinuous reception) for the terminal through layer 3RRC signaling, such as one or more of effective time, a service type used, whether exception items (i.e., the above specific transmission actions) are allowed, and the like.

Step two: the network side sends a discontinuous reception command (DRX command) when needed, and does not send downlink transmission to the terminal in the discontinuous reception period of the terminal (namely the effective time of the terminal);

step three: the network side can send downlink transmission to the terminal after the terminal discontinuous reception time is over, and can send the discontinuous reception command again if necessary.

Correspondingly, the terminal of the first embodiment performs the steps including:

step two: the terminal receives a discontinuous receiving command sent by the network side and enters a discontinuous receiving state, and the discontinuous receiving time starts to time from the discontinuous receiving command received by the terminal; it should be noted that, in this step, although the timing is started from the time of receiving the discontinuous reception command, the terminal substantially executes the discontinuous reception state only after the data transmission currently in progress is finished;

step three: and after the time for executing the discontinuous reception is over, the terminal enters an activated state and continuously monitors downlink transmission until a discontinuous reception command is received next time.

Based on the flow of the first embodiment, assuming that the terminal does not allow any exception item after entering the inactive state, and does not generate a new first service that is not suitable for discontinuous reception, a timing diagram of the terminal in the active state and the inactive state is shown in fig. 3, and it can be seen from fig. 3 that once the terminal enters the inactive state, the time lasts until the end time of the effective time.

Example two

The network side device of the second embodiment only dynamically sends the discontinuous reception command, and the configuration corresponding to the discontinuous reception to the parameter set is configured in advance by the terminal side or specified by the terminal side according to the protocol.

The parameter set pre-configured by the terminal or specified by the protocol for discontinuous reception may include one or more of the following:

discontinuous reception time length: index numbers that can be of a specific length of time or in all possible lengths;

the applicable service types are as follows: ID numbers of RB, RBG, LC, LCG and slice introduced in the embodiment;

whether exception items are allowed: such as whether to allow uplink transmissions to be sent during discontinuous reception.

the method comprises the following steps: the network side equipment sends a discontinuous reception command when needed, wherein the discontinuous reception command does not carry discontinuous reception configuration information and does not send downlink transmission to the terminal within the effective time of the discontinuous reception of the terminal;

step two: the network side can send downlink transmission to the terminal after the effective time of the terminal executing discontinuous reception is over, and can send a discontinuous reception command again if necessary.

Wherein, the terminal execution step includes:

the method comprises the following steps: the terminal receives a discontinuous receiving command to be sent by a network side, enters a discontinuous receiving state after the current ongoing data transmission is finished, and starts timing from the time of receiving the discontinuous receiving command;

step two: and after the discontinuous receiving time is over, the terminal enters an activated state and continuously monitors downlink transmission until a discontinuous receiving command is received next time.

Based on the flow of the second embodiment, assuming that the terminal does not allow any exception item after entering the inactive state, and does not generate a new first service that is not suitable for discontinuous reception, the timings of the active state and the inactive state of the terminal within the effective time are as shown in fig. 4, and as can be seen from fig. 4, once the terminal is in the inactive state, the terminal continues to the end time of the effective time.

EXAMPLE III

In the third embodiment, the network side device notifies the terminal to enter discontinuous reception (without distinguishing service requirements) by using any one of the first and second embodiments, and the configuration information in the discontinuous reception command does not include a service type applicable to discontinuous reception and a service type not applicable to discontinuous reception.

Wherein, the network side step includes:

the method comprises the following steps: the network side equipment sends discontinuous reception row signaling to the terminal, the discontinuous reception command does not have service correlation, namely bears RB related information, and the terminal does not send downlink transmission to the terminal within the effective time.

Step two: the network side device may send downlink transmission to the terminal after the terminal discontinuous reception time is over, and may send the discontinuous reception command again if necessary.

The terminal comprises the following execution steps:

step two: and after the discontinuous reception duration is over, the terminal enters an activated state and continuously monitors downlink transmission until a discontinuous reception command is received next time.

Based on the process of the third embodiment, it is assumed that the terminal enters the inactive state until the end time of the effective time if receiving the configuration information about the service type direction. The corresponding timing diagram is shown in fig. 5.

Example four

In the fourth embodiment, the network side instructs the terminal to enter the discontinuous reception state only for the designated service.

The network side device may notify the terminal to execute the discontinuous reception state in any one of the first and second embodiments. The discontinuous reception command received continuously carries configuration information, and carries relevant information for informing the terminal that data for a specific service is valid.

In the fourth embodiment, it is assumed that RB1 with low latency requirement is indicated to be in effect in the configuration information, and RB2 with high latency requirement is not indicated to be in effect. The bearer generally refers to an uplink bearer (i.e., both RB1 and RB2 are uplink bearers) because whether there is downlink bearer data controlled by the network side and whether there is uplink bearer data determined by the terminal side.

The network side equipment executes the steps of:
