The present application claims the priority of Chinese Application No. 202210027781.8, filed on Jan. 11, 2022, the disclosure of which is incorporated in its entirety by reference herein.
The present disclosure relates to the field of communication technologies, and in particular to a discontinuous reception timer control method, device, user equipment and network device.
At present, for special Hybrid Automatic Repeat reQuest (HARQ) feedback type (i.e., feedback type triggered by downlink control information (DCI) scheduling), in case that a base station instructs a user equipment (UE) to provide feedback on all carriers and all HARQ processes at one time, if the UE has started a discontinuous reception (DRX) downlink retransmission timer for one HARQ process, the downlink retransmission timer needs to be stopped, and the UE cannot receive retransmission scheduling of the base station. Special HARQ feedback is for multiple processes, especially Type-3 HARQ-ACK codebook is for all HARQ processes, which means that all HARQ processes involved must stop DRX downlink retransmission timers that may have been started, which is obviously not conducive to the timely retransmission scheduling of the base station. Similarly, if DRX downlink round-trip-time (RTT) timers have been started for some processes and corresponding DRX downlink retransmission timer will soon be started, the start of the new RTT timer will interrupt this process (as shown in

The terminal involved in the embodiments of the present disclosure is a device for providing voice data and/or any other service data to a user, e.g., a handheld device having a wireless connection function, or any other processing device capable of being connected to a wireless modem. In different systems, the terminal device may have different names. For example, in a 5G system, the terminal device is called as User Equipment (UE). A wireless terminal device communicates with one or more Core Networks (CNs) via a Radio Access Network (RAN). The wireless terminal device may be a mobile terminal, e.g., a mobile phone (or cellular phone), or a computer having the mobile terminal device, e.g., a portable, pocket-sized, handheld, built-in or vehicle-mounted mobile device, which are capable of exchanging voice and/or data with the RAN. For example, the wireless terminal device may be a Personal Communication Service (PCS) telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, or a Personal Digital Assistant (PDA). In addition, the wireless terminal device may also be called as system, subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, access terminal, user terminal, user agent or user device, which will not be particularly defined herein.
The network device involved in the embodiments of the present disclosure may be a base station which includes a plurality of cells providing services for the terminal.

Contents involved in the solution provided in the embodiment of the present disclosure are introduced hereinafter.
DRX refers to discontinuous reception mechanism of a UE in a connected state. This mechanism allows the UE to periodically enter a sleep state at certain moments and not monitor Physical downlink control channel (PDCCH) sub-frame. When it is needed to monitor PDCCH sub-frame, the UE wakes up from the sleep state, so that the UE can save power. The DRX mechanism (DRX cycle) in the connected state is shown in
In addition, DRX operation mainly involves: drx-onDurationTimer (DRX duration timer), drx-Inactivity Timer (DRX inactivity timer), drx-RetransmissionTimerDL (DRX downlink retransmission timer), drx-RetransmissionTimerUL (DRX uplink retransmission timer), drx-HARQ-RTT-TimerDL (DRX downlink round-trip-time (RTT) timer) and drx-HARQ-RTT-TimerUL (per UL HARQ process) (DRX uplink RTT timer). During operation of the drx-onDurationTimer, drx-Inactivity Timer (DRX inactivity timer), drx-RetransmissionTimerDL (DRX downlink retransmission timer) and drx-RetransmissionTimerUL (DRX uplink retransmission timer), the UE is in DRX inactive state and needs to monitor PDCCH scheduling of a base station. During operation of the drx-HARQ-RTT-TimerDL and drx-HARQ-RTT-TimerUL, the UE is in DRX inactive state and does not need to monitor the PDCCH scheduling of the base station.
This solution is mainly related to drx-HARQ-RTT-TimerDL and drx-RetransmissionTimerDL. Both timers run for each HARQ process. The specific operation mode includes: when the UE receives downlink data sent by the base station and sends HARQ feedback, drx-HARQ-RTT-TimerDL is started. When the drx-HARQ-RTT-TimerDL is started, the drx-RetransmissionTimerDL of the corresponding HARQ process is stopped; when the drx-HARQ-RTT-TimerDL expires, if the UE does not correctly receive downlink transmission of this HARQ process, drx-RetransmissionTimerDL is started. In this way, the base station and the UE have the same understanding of when the UE is in the DRX active state and the inactive state, and the base station can schedule the UE during the operation of drx-RetransmissionTimerDL.
In addition, 5G introduces new HARQ feedback types, including:
From the above, it is necessary to solve how to control the DRX timer (including DRX downlink RTT timer and DRX downlink retransmission timer) after the UE sends a special state Hybrid automatic repeat request (HARQ) feedback during discontinuous reception (DRX) operation, so that the base station and the UE have a consistent understanding of the DRX state, thereby enabling the base station to schedule data retransmission in time.
Based on the above, embodiments of the present disclosure provide a discontinuous reception timer control method, device, UE and network device to solve the problem in the related art that retransmission scheduling cannot be carried out in time caused by the discontinuous reception timer control scheme for special HARQ feedback types. The method, device, UE and network device are based on the same application concept. Since the principles of solving the problem by the method, device, UE and network device are similar, the implementation of the method, device, UE and network device can refer to each other, and the repeated parts will not be repeated.
A discontinuous reception timer control method provided by one embodiment of the present disclosure is applied to a user equipment (UE), as shown in
Step 41: after performing a first hybrid automatic repeat request (HARQ) feedback, performing a first control operation on a DRX downlink retransmission timer corresponding to at least one first HARQ process; where the first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling; the first HARQ process refers to a HARQ process for which a first DRX downlink RTT timer has been started or a HARQ process for which a first DRX downlink retransmission timer has been started, before performing the first HARQ feedback, among the HARQ processes corresponding to the first HARQ feedback; the first control operation includes at least one of the following: in case that the first DRX downlink RTT timer expires and downlink data is not correctly received, starting a second DRX retransmission timer; or maintaining or restarting the first DRX downlink retransmission timer.
The “correctly received” may mean that the UE can correctly decode downlink data transmitted in the process, but is not limited thereto.
The discontinuous reception timer control method provided by the embodiment of the present disclosure performs a first control operation on the DRX downlink retransmission timer corresponding to at least one first HARQ process after performing a first HARQ feedback; where the first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling; the first HARQ process refers to a HARQ process for which a first DRX downlink RTT timer has been started or a HARQ process for which a first DRX downlink retransmission timer has been started, before performing the first HARQ feedback, among the HARQ processes corresponding to the first HARQ feedback; the first control operation includes at least one of the following: in case that the first DRX downlink RTT timer expires and downlink data is not correctly received, starting a second DRX retransmission timer; or maintaining or restarting the first DRX downlink retransmission timer. In this way, the method can support the UE to send HARQ feedbacks of multiple HARQ processes at the same time according to an instruction of the network device; or, avoid the DRX downlink retransmission timer from being stopped or delayed in case of retransmitting HARQ feedback according to an instruction of the network device, so that for the HARQ process that has started the DRX downlink RTT timer or DRX downlink retransmission timer, the retransmission scheduling can be obtained early, thereby ensuring that the retransmission scheduling can be performed in time. Therefore, the method can effectively solve the problem in the related art that retransmission scheduling cannot be carried out in time caused by the discontinuous reception timer control scheme for special HARQ feedback types.
The HARQ feedback triggered by the DCI scheduling includes at least one of the following: HARQ feedbacks of all current carriers and all HARQ processes fed back by the UE at one time (which is specifically corresponding to that DCI indicates to feedback Type-3 HARQ-ACK code on PUCCH); or HARQ feedbacks of some carriers and/or some HARQ processes fed back by the UE at one time (which is specifically corresponding to that DCI indicates to feedback enhanced Type-3 HARQ-ACK code on PUCCH); or the last HARQ feedback retransmitted by the UE.
In the embodiment of the present disclosure, when the first DRX downlink RTT timer expires and the downlink data is not correctly received, starting the second DRX retransmission timer, includes: in case that the first DRX downlink RTT timer has been started before performing the first HARQ feedback, continuing to run the first DRX downlink RTT timer and not starting other DRX downlink RTT timers; in case that the first DRX downlink RTT timer expires and the downlink data is not correctly received, starting the second DRX retransmission timer; or, in case that the first DRX downlink RTT timer has been started before performing the first HARQ feedback, continuing to run the first DRX downlink RTT timer and starting the second DRX downlink RTT timer; in case that the first DRX downlink RTT timer expires and the downlink data is not correctly received, starting the second DRX retransmission timer, and restarting the second DRX retransmission timer in case that the second DRX downlink RTT timer expires.
Regarding “continuing to run”, it can also be understood as “continuing to maintain”, which is not limited here. Regarding “not starting other DRX downlink RTT timers”, it may mean not starting other DRX downlink RTT timers for the first HARQ process except the first DRX downlink RTT timer; it may also include not restarting the first DRX downlink RTT timer. Or, “not starting other DRX downlink RTT timers” can also be understood as: not starting DRX downlink RTT timer corresponding to the first HARQ feedback, which is not limited here.
The maintaining or restarting the first DRX downlink retransmission timer, includes: in case that the first DRX downlink retransmission timer has been started before performing the first HARQ feedback, continuing to run the first DRX downlink retransmission timer and not starting the DRX downlink RTT timer corresponding to the first HARQ process; or, in case that the first DRX downlink retransmission timer has been started before performing the first HARQ feedback, continuing to run the first DRX downlink retransmission timer and starting a third DRX downlink RTT timer; in case that the first DRX downlink retransmission timer expires and downlink data packet is not received correctly, extending duration of DRX downlink retransmission timing; or, in case that the first DRX downlink retransmission timer has been started before performing the first HARQ feedback and the downlink data packet is not received correctly, restarting the first DRX downlink retransmission timer.
It is to be noted that, optionally, the maintaining or restarting the first DRX downlink retransmission timer may also include the following solutions:
The application end of the solution in this implementation is not limited here, that is, this implementation can be applied to a UE or a network device, and this implementation will not be repeated in the implementation of the network device.
In the embodiment of the present disclosure, the extending duration of DRX downlink retransmission timing, includes any one of the following: (1) starting a third DRX downlink retransmission timer in case that the third DRX downlink RTT timer expires; (2) setting the UE to an active state in a time period between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer, and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer expires; (3) extending duration of the first DRX downlink retransmission timer to a starting moment of the third DRX downlink retransmission timer; and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer expires; (4) extending the duration of the first DRX downlink retransmission timer to a first duration; the first duration is equal to a sum of the first DRX downlink retransmission timer, the third DRX downlink retransmission timer and a time gap, and the time gap is a time interval between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer.
In the embodiment of the present disclosure, the first DRX downlink retransmission timer expires first, and the started third DRX downlink RTT timer expires afterwards, with a time gap therebetween. The started third DRX downlink RTT Timer is used to start the third DRX downlink retransmission timer.
In addition, during operation of the first DRX downlink retransmission timer and/or the third DRX downlink retransmission timer, the UE enters an active state and monitors PDCCH scheduling.
One embodiment of the present disclosure further provides a discontinuous reception timer control method, which is applied to a network device, as shown in
Step 51: after receiving a first hybrid automatic repeat request (HARQ) feedback, performing a first control operation on a DRX downlink retransmission timer corresponding to at least one first HARQ process; where the first HARQ feedback is a HARQ feedback triggered by DCI scheduling; the first HARQ process refers to a HARQ process for which a first DRX downlink RTT timer has been started or a HARQ process for which a first DRX downlink retransmission timer has been started, before receiving the first HARQ feedback, among the HARQ processes corresponding to the first HARQ feedback; the first control operation includes at least one of the following: in case that the first DRX downlink RTT timer expires and the first HARQ feedback includes a first acknowledgment feedback, starting a second DRX retransmission timer, where the first acknowledgment feedback is a HARQ negative acknowledgment feedback for the first HARQ process; or, maintaining or restarting the first DRX downlink retransmission timer.
The “receiving the first HARQ feedback” may specifically include: receiving the first HARQ feedback sent by the UE; the “first HARQ feedback includes a first response feedback” corresponds to “not correctly received” on the UE side, and “correctly received” may mean that the UR can correctly decode downlink data transmitted in the process, but is not limited to this.
The discontinuous reception timer control method provided by the embodiment of the present disclosure performs a first control operation on the DRX downlink retransmission timer corresponding to at least one first HARQ process after receiving a first HARQ feedback; where the first HARQ feedback is a HARQ feedback triggered by downlink control information (DCI) scheduling; the first HARQ process refers to a HARQ process for which a first DRX downlink RTT timer has been started or a HARQ process for which a first DRX downlink retransmission timer has been started, before receiving the first HARQ feedback, among the HARQ processes corresponding to the first HARQ feedback; the first control operation includes at least one of the following: in case that the first DRX downlink RTT timer expires and the first HARQ feedback includes a first acknowledgment feedback, starting a second DRX retransmission timer, where the first acknowledgment feedback is a HARQ negative acknowledgment feedback for the first HARQ process; or, maintaining or restarting the first DRX downlink retransmission timer. In this way, the method can support the UE to send HARQ feedbacks of multiple HARQ processes at the same time according to an instruction of the network device; or, avoid the DRX downlink retransmission timer from being stopped or delayed in case of retransmitting HARQ feedback according to an instruction of the network device, so that for the HARQ process that has started the DRX downlink RTT timer or DRX downlink retransmission timer, the retransmission scheduling can be obtained early, thereby ensuring that the retransmission scheduling can be performed in time (that is, the network device can schedule data retransmission in time). Therefore, the method can effectively solve the problem in the related art that retransmission scheduling cannot be carried out in time caused by the discontinuous reception timer control scheme for special HARQ feedback types.
The HARQ feedback triggered by the DCI scheduling includes at least one of the following: HARQ feedbacks of all current carriers and all HARQ processes fed back by the UE at one time (which is specifically corresponding to that DCI indicates to feedback Type-3 HARQ-ACK code on PUCCH); or HARQ feedbacks of some carriers and/or some HARQ processes fed back by the UE at one time (which is specifically corresponding to that DCI indicates to feedback enhanced Type-3 HARQ-ACK code on PUCCH); or the last HARQ feedback retransmitted by the UE.
In the embodiment of the present disclosure, when the first DRX downlink RTT timer expires and the first HARQ feedback includes a first acknowledgment feedback, starting the second DRX retransmission timer, includes: in case that the first DRX downlink RTT timer has been started before receiving the first HARQ feedback, continuing to run the first DRX downlink RTT timer and not starting other DRX downlink RTT timers; in case that the first DRX downlink RTT timer expires and the first HARQ feedback includes the first acknowledgment feedback, starting the second DRX retransmission timer; or, in case that the first DRX downlink RTT timer has been started before receiving the first HARQ feedback, continuing to run the first DRX downlink RTT timer and starting the second DRX downlink RTT timer; in case that the first DRX downlink RTT timer expires and the first HARQ feedback includes the first acknowledgment feedback, starting the second DRX retransmission timer, and restarting the second DRX retransmission timer in case that the second DRX downlink RTT timer expires.
Regarding “continuing to run”, it can also be understood as “continuing to maintain”, which is not limited here. Regarding “not starting other DRX downlink RTT timers”, it may mean not starting other DRX downlink RTT timers for the first HARQ process except the first DRX downlink RTT timer; it may also include not restarting the first DRX downlink RTT timer. Or, “not starting other DRX downlink RTT timers” can also be understood as: not starting DRX downlink RTT timer corresponding to the first HARQ feedback, which is not limited here.
The maintaining or restarting the first DRX downlink retransmission timer, includes: in case that the first DRX downlink retransmission timer has been started before receiving the first HARQ feedback, continuing to run the first DRX downlink retransmission timer and not starting the DRX downlink RTT timer corresponding to the first HARQ process; or, in case that the first DRX downlink retransmission timer has been started before receiving the first HARQ feedback, continuing to run the first DRX downlink retransmission timer and starting a third DRX downlink RTT timer; in case that the first DRX downlink retransmission timer expires and the first HARQ feedback includes the first acknowledgment feedback, extending duration of DRX downlink retransmission timing; or, in case that the first DRX downlink retransmission timer has been started before receiving the first HARQ feedback and the first HARQ feedback includes the first acknowledgment feedback, restarting the first DRX downlink retransmission timer.
In the embodiment of the present disclosure, the extending duration of DRX downlink retransmission timing, includes any one of the following: (1) starting a third DRX downlink retransmission timer in case that the third DRX downlink RTT timer expires; (2) setting the UE to an active state in a time period between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer, and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer expires; (3) extending duration of the first DRX downlink retransmission timer to a starting moment of the third DRX downlink retransmission timer; and starting the third DRX downlink retransmission timer when the third DRX downlink RTT timer expires; (4) extending the duration of the first DRX downlink retransmission timer to a first duration; the first duration is equal to a sum of the first DRX downlink retransmission timer, the third DRX downlink retransmission timer and a time gap, and the time gap is a time interval between the first DRX downlink retransmission timer and the third DRX downlink retransmission timer.
The “UE” in the above option (2) may specifically be a UE that sends the first HARQ feedback, which is not limited here.
In the embodiment of the present disclosure, the first DRX downlink retransmission timer expires first, and the started third DRX downlink RTT timer expires afterwards, with a time gap therebetween. The started third DRX downlink RTT Timer is used to start the third DRX downlink retransmission timer.
In addition, during operation of the first DRX downlink retransmission timer and/or the third DRX downlink retransmission timer, the UE enters an active state and the network device can send a PDCCH scheduling instruction (i.e., a scheduling command) to the UE.
The discontinuous reception timer control method provided in the embodiment of the present disclosure is described hereinafter by taking an example of a base station as an example of a network device.
In view of the above technical problems, one embodiment of the present disclosure provides a discontinuous reception timer control method, which mainly involves: after the UE sends a special type of HARQ feedback (corresponding to the above first HARQ feedback), the DRX downlink retransmission timer (drx-RetransmissionTimerDL) in the HARQ process (corresponding to the above first HARQ process) corresponding to the HARQ feedback is specially processed (corresponding to the above first control operation), so that the UE can monitor PDCCH scheduling commands of the base station in a timely manner (or as soon as possible) (that is, the UE can receive the PDCCH in a timely manner (or as soon as possible)).
Specifically, the present solution involves the following contents.
The present disclosure takes into account that the base station needs to maintain a timer, otherwise the base station does not know when the UE is in the active period, and thus does not know when to send a scheduling command. Therefore, the base station can perform timer control operations similar to those of the UE, which will not be repeated here.
The following is a specific example of the solution provided by the embodiment of the present disclosure.
In the figure of this example, the base station instructs the UE to send HARQ feedback (i.e., the above special type HARQ feedback types 1 and 2) of multiple processes at one time as an example. When the base station instructs the UE to send HARQ feedback retransmission (i.e., the special type HARQ feedback type 3), the operation is the same and will not be repeated here.
In the figure of this example, the base station instructs the UE to send HARQ feedback (i.e., the above special type HARQ feedback types 1 and 2) of multiple processes at one time as an example. When the base station instructs the UE to send HARQ feedback retransmission (i.e., the special type HARQ feedback type 3), the operation is the same and will not be repeated here.

It is to be noted that similar contents in the above examples can be referenced to each other and will not be repeated here.
From the above, when the UE sends the HARQ feedback of multiple HARQ processes at the same time according to an instruction of the base station, or when retransmitting HARQ feedback according to an instruction of the base station, the solution can obtain the retransmission scheduling of the base station as early as possible for the HARQ process for which the DRX downlink RTT timer or the DRX downlink retransmission timer has been started.
One embodiment of the present disclosure further provides a user equipment (UE), as shown in
The memory 111 is used to store a computer program; the transceiver 112 is used to send and receive data under control of the processor 113; the processor 113 is used to read the computer program in the memory 111 and perform the following operations:
