Description

DRX定时器控制方法、装置、终端及存储介质DRX timer control method, device, terminal and storage medium

技术领域Technical field

本申请涉及通信技术领域，特别涉及一种DRX定时器控制方法、装置、终端及存储介质。This application relates to the field of communication technology, and in particular to a DRX timer control method, device, terminal and storage medium.

背景技术Background technique

在NR-U(New Radio Unlicensed，新无线非授权)中，基站在调度终端之前需要侦听非授权频谱的信道是否可用，且可用信道存在MCOT(Maximum Channel Occupy Time，最大信道占用时间)，对于终端而言在该MCOT内才有可能被调度。In NR-U (New Radio Unlicensed), the base station needs to monitor whether the channel of the unlicensed spectrum is available before scheduling the terminal, and the available channel has MCOT (Maximum Channel Occupy Time). For The terminal can be scheduled within the MCOT.

在NR-U中，终端可以使用DRX(Discontinuous Reception，非连续接收)机制非连续地监听PDCCH(Physical Downlink Control Channel，物理下行控制信道)，从而达到省电目的。在DRX机制中，终端维护多种DRX定时器，譬如包括DRX持续定时器、DRX非激活定时器、DRX下行重传定时器、DRX上行重传定时器和随机接入竞争解决定时器，且终端在时域上被划分成连续的多个DRX周期，每个DRX周期包括活跃期和睡眠期，终端在上述任一种DRX定时器运行期间处于活跃期，需要监听PDCCH。如果终端在DRX定时器运行期间没有被基站调度，则在DRX定时器超时后可能进入睡眠期，此时终端不监听PDCCH。然而，由于基站成功抢占到信道时终端可能进入睡眠期，将导致无法成功调度终端，使得终端非连续接收失败。In NR-U, the terminal can use the DRX (Discontinuous Reception) mechanism to non-continuously monitor the PDCCH (Physical Downlink Control Channel) to save power. In the DRX mechanism, the terminal maintains a variety of DRX timers, including DRX duration timer, DRX inactive timer, DRX downlink retransmission timer, DRX uplink retransmission timer, and random access contention resolution timer. It is divided into multiple consecutive DRX cycles in the time domain. Each DRX cycle includes an active period and a sleep period. The terminal is in the active period during the operation of any of the above DRX timers and needs to monitor the PDCCH. If the terminal is not scheduled by the base station during the running of the DRX timer, it may enter a sleep period after the DRX timer expires, and the terminal does not monitor the PDCCH at this time. However, since the terminal may enter a sleep period when the base station successfully seizes the channel, the terminal cannot be successfully scheduled, and the terminal fails to receive discontinuously.

为了提高终端被成功调度的概率，目前提出了为终端配置更长的定时器时长，或者将为终端配置的DRX周期的时长缩小一定时长阈值，从而增大终端被调度的概率。然而，如此也增加了终端的功耗。In order to increase the probability of the terminal being successfully scheduled, it is currently proposed to configure a longer timer duration for the terminal, or to reduce the duration of the DRX cycle configured for the terminal by a certain duration threshold, thereby increasing the probability of the terminal being scheduled. However, this also increases the power consumption of the terminal.

具体实施方式Detailed ways

为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。In order to make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

在对本申请实施例提供的DRX定时器的控制方法进行详细介绍之前，先对本申请实施例涉及的应用场景和实施环境进行简单介绍。Before describing in detail the DRX timer control method provided in the embodiments of the present application, a brief introduction to the application scenarios and implementation environments involved in the embodiments of the present application will be given first.

首先，对本申请实施例涉及的应用场景进行简单介绍。First, the application scenarios involved in the embodiments of the present application are briefly introduced.

目前，如果终端定制了DRX机制，则终端通常需要在DRX活跃期监听PDCCH信道。作为一种示例，终端处于DRX活跃期至少包括如下的情况：终端维护的DRX持续定时器(DRX-onDurationTimer)、DRX非激活定时器(DRX-InactivityTimer)、DRX下行重传定时器(DRX-RetransmissionTimerDL)、DRX上行重传定时器(DRX-RetransmissionTimerUL)和随机接入竞争解决定时器(Ra-ContentionResolutionTimer)这5个定时器中的任一个DRX定时器正在运行。Currently, if the terminal customizes the DRX mechanism, the terminal usually needs to monitor the PDCCH channel during the DRX active period. As an example, the terminal being in the DRX active period includes at least the following situations: DRX duration timer (DRX-onDurationTimer) maintained by the terminal, DRX inactivity timer (DRX-InactivityTimer), DRX downlink retransmission timer (DRX-RetransmissionTimerDL) ), DRX uplink retransmission timer (DRX-RetransmissionTimerUL) and random access contention resolution timer (Ra-ContentionResolutionTimer), any one of the DRX timers is running.

在目前的DRX机制中，上述五种定时器的启动条件或重启条件分别为：In the current DRX mechanism, the start conditions or restart conditions of the above five timers are:

DRX持续定时器：终端根据当前是处于短DRX周期还是长DRX周期来决定其启动时间，具体规定如下：如果使用的是短DRX周期，并且当前子帧满足[(SFN×10)+subframe number]modulo(drx-ShortCycle)＝(drx-StartOffset)modulo(drx-ShortCycle)；或者，如果使用的是长DRX周期，并且当前子帧满足[(SFN×10)+subframe number]modulo(drx-LongCycle)＝drx-StartOffset。其中，上述公式中的[(SFN×10)+subframe number]表示当前子帧号，drx-ShortCycle表示短DRX周期，drx-LongCycle表示长DRX周期，drx-StartOffset为网络配置的偏移量，modulo表示取模运算。进一步地，在当前子帧开始的drx-SlotOffset个时隙之后的时刻启动DRX持续定时器，该drx-SlotOffset可以由网络配置。DRX duration timer: The terminal determines its start time according to whether it is currently in a short DRX cycle or a long DRX cycle. The specific provisions are as follows: If a short DRX cycle is used and the current subframe satisfies [(SFN×10)+subframe number] modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle); or, if the long DRX cycle is used, and the current subframe satisfies [(SFN×10)+subframe number]modulo(drx-LongCycle) =drx-StartOffset. Among them, [(SFN×10)+subframe number] in the above formula represents the current subframe number, drx-ShortCycle represents the short DRX cycle, drx-LongCycle represents the long DRX cycle, drx-StartOffset is the offset of the network configuration, modulo Represents modulo operation. Further, the DRX persistence timer is started at a moment after the drx-SlotOffset timeslots from the beginning of the current subframe, and the drx-SlotOffset can be configured by the network.

DRX非激活定时器：如果终端接收到一个指示下行或者上行初始传输的PDCCH数据，则终端启动或者重启DRX非激活定时器。DRX inactive timer: If the terminal receives a PDCCH data indicating downlink or uplink initial transmission, the terminal starts or restarts the DRX inactive timer.

DRX下行重传定时器：如果终端接收到一个指示下行传输的PDCCH，或者如果终端在配置的下行授权资源上接收到一个MAC(Media Access Control，介质访问控制)PDU(Protocol Data Unit，协议数据单元)，则终端在完成针对这次下行传输的HARQ(Hybrid Automatic Repeat ReQuest，混合自动重传请求)进程反馈的传输之后启动该HARQ进程对应的DRX-HARQ-RTT-TimerDL，同时停止该HARQ进程对应的DRX下行重传定时器。如果终端的某个HARQ对应的定时器DRX-HARQ-RTT-TimerDL超时，并且使用这个HARQ进程传输的下行数据解码不成功，则终端启动这个HARQ进程对应的DRX下行重传定时器。DRX Downlink Retransmission Timer: If the terminal receives a PDCCH indicating downlink transmission, or if the terminal receives a MAC (Media Access Control, Media Access Control) PDU (Protocol Data Unit) on the configured downlink authorized resource ), the terminal starts the DRX-HARQ-RTT-TimerDL corresponding to the HARQ process after completing the transmission of the HARQ (Hybrid Automatic Repeat ReQuest) process feedback for this downlink transmission, and stops the HARQ process corresponding DRX downlink retransmission timer. If the timer DRX-HARQ-RTT-TimerDL corresponding to a certain HARQ of the terminal times out, and the downlink data transmitted using this HARQ process is not successfully decoded, the terminal starts the DRX downlink retransmission timer corresponding to this HARQ process.

DRX上行重传定时器：如果终端接收到一个指示上行传输的PDCCH，或者如果终端在配置的上行授权资源上发送一个MAC PDU，则终端在完成这次上行传输之后启动该HARQ进程对应的DRX-HARQ-RTT-TimerUL，同时停止该HARQ进程对应的DRX上行重传定时器。如果终端的某个HARQ对应的定时器DRX-HARQ-RTT-TimerUL超时，则终端启动这个HARQ进程对应的DRX上行重传定时器。DRX uplink retransmission timer: If the terminal receives a PDCCH indicating uplink transmission, or if the terminal sends a MAC PDU on the configured uplink authorization resource, the terminal starts the DRX-corresponding HARQ process after completing this uplink transmission. HARQ-RTT-TimerUL, and at the same time stop the DRX uplink retransmission timer corresponding to the HARQ process. If the timer DRX-HARQ-RTT-TimerUL corresponding to a certain HARQ of the terminal expires, the terminal starts the DRX uplink retransmission timer corresponding to this HARQ process.

随机接入竞争解决定时器：在随机接入过程中，当MSG3发送之后，终端开始启动这个随机接入竞争解决定时器，在这段时间内终端不断监控PDCCH信道。如果随机接入竞争解决定时器超时，则需要重新发起随机接入过程。Random access contention resolution timer: In the random access process, after MSG3 is sent, the terminal starts this random access contention resolution timer, and the terminal continuously monitors the PDCCH channel during this period. If the random access contention resolution timer expires, the random access procedure needs to be re-initiated.

接下来，对本申请实施例涉及的实施环境进行简单介绍。Next, the implementation environment involved in the embodiments of the present application will be briefly introduced.

请参考图1，该图1是根据一示例性实施例示出的一种实施环境的示意图，该实施环境中主要包括终端110和基站120，其中，该终端110可以通过通信网络接入该基站120。该基站120可以调度该终端110，进一步地，在NR-U业务场景中，该基站120可以在成功抢占到信道后调度该终端110，该终端110可以用于执行本申请实施例提供的DRX定时器控制方法。Please refer to FIG. 1, which is a schematic diagram showing an implementation environment according to an exemplary embodiment. The implementation environment mainly includes a terminal 110 and a base station 120. The terminal 110 can access the base station 120 through a communication network. . The base station 120 can schedule the terminal 110. Further, in an NR-U service scenario, the base station 120 can schedule the terminal 110 after successfully seizing the channel, and the terminal 110 can be used to execute the DRX timing provided in the embodiment of the application器控制方法。 Control method.

请参考图2，该图2是根据一示例性实施例示出的一种DRX定时器控制方法的流程图，该方法可以应用于上述图1所示的实时环境中，主要由终端来执行，该方法可以包括如下几个实现步骤：Please refer to FIG. 2, which is a flowchart of a method for controlling a DRX timer according to an exemplary embodiment. The method can be applied to the real-time environment shown in FIG. 1 and is mainly executed by the terminal. The method can include the following implementation steps:

步骤201：监听用于指示成功抢占到非授权频谱上的信道的第一信道占用指示。Step 201: Monitor the first channel occupancy indication used to indicate that the channel on the unlicensed spectrum is successfully preempted.

作为一种示例，该第一信道占用指示可以为DMRS(Demodulation Reference Symbol，解调参考信号)，或者，该第一信道占用指示可以为PDCCH上传输的信号。As an example, the first channel occupation indication may be a DMRS (Demodulation Reference Symbol, demodulation reference signal), or the first channel occupation indication may be a signal transmitted on the PDCCH.

在NR-U中，基站在调度终端之前需要侦听NR-U上的信道，如果侦听结果表示该信道为空闲状态，当成功抢占到信道后，该基站可以向终端发送第一信道占用指示，以通过该第一信道占用指示通知终端已成功抢占到信道。否则，如果侦听结果表示该信道为占用状态，则基站不给终端发送该第一信道占用指示。In NR-U, the base station needs to listen to the channel on NR-U before scheduling the terminal. If the listening result indicates that the channel is in an idle state, when the channel is successfully seized, the base station can send the first channel occupation indication to the terminal , To notify the terminal that the channel has been successfully preempted through the first channel occupation indication. Otherwise, if the listening result indicates that the channel is in an occupied state, the base station does not send the first channel occupation indication to the terminal.

作为一种示例，当该第一信道占用指示为DMRS时，该基站可以在成功抢占到非授权频谱上的信道后向终端发送DMRS，对于终端来说，如果接收到该DMRS，则可以确定基站已经成功抢占到非授权频谱上的信道。As an example, when the first channel occupancy indication is a DMRS, the base station can send a DMRS to the terminal after successfully seizing the channel on the unlicensed spectrum. For the terminal, if the DMRS is received, the base station can be determined Has successfully seized the channel on the unlicensed spectrum.

作为另一种示例，当该第一信道占用指示为PDCCH上传输的信号时，该基站可以在成功抢占到非授权频谱上的信道后在该PDCCH上传输该第一信道占用指示，对于终端来说，盲检用于传输该第一信道占用指示的PDCCH，当监听到该第一信道占用指示时，可以确定基站已经成功抢占到非授权频谱上的信道。作为一种示例，该终端可以一直盲检该PDCCH，或者，该终端也可以周期性检测该PDCCH，以监听该第一信道占用指示。As another example, when the first channel occupancy indication is a signal transmitted on the PDCCH, the base station may transmit the first channel occupancy indication on the PDCCH after successfully seizing the channel on the unlicensed spectrum. In other words, blind detection is used to transmit the PDCCH of the first channel occupancy indication. When the first channel occupancy indication is monitored, it can be determined that the base station has successfully preempted the channel on the unlicensed spectrum. As an example, the terminal may always blindly detect the PDCCH, or the terminal may also periodically detect the PDCCH to monitor the first channel occupation indication.

进一步地，该终端可以以低功率模式监听该第一信道占用指示，此时，监听用于指示成功抢占到非授权频谱上的信道的第一信道占用指示的具体实现可以包括如下实现方式中的任一种：Further, the terminal may monitor the first channel occupancy indication in a low-power mode. At this time, the specific implementation of listening to the first channel occupancy indication used to indicate successful preemption of the channel on the unlicensed spectrum may include the following implementations Either:

第一种实现方式：使用低功率接收机监听用于指示成功抢占到非授权频谱上的信道的第一信道占用指示，该低功率接收机的接收功率小于功率阈值。The first implementation manner: a low-power receiver is used to monitor the first channel occupancy indication used to indicate successful preemption of channels on the unlicensed spectrum, and the received power of the low-power receiver is less than the power threshold.

其中，该功率阈值可以根据实际需求进行设置，或者，也可以由该终端默认设置，本申请实施例对此不作限定。The power threshold may be set according to actual needs, or may also be set by default by the terminal, which is not limited in the embodiment of the present application.

也即是，终端可以使用一个特定的低功率接收机来监听并接收该第一信道占用指示，该低功率接收机的接收功率通常比较低，从而实现以低功率模式监听并接收。That is, the terminal may use a specific low-power receiver to monitor and receive the first channel occupancy indication, and the received power of the low-power receiver is usually relatively low, so as to achieve monitoring and reception in a low-power mode.

第二种实现方式：降低目标接收参数，基于降低处理后的目标接收参数监听用于指示成功抢占到非授权频谱上的信道的第一信道占用指示。The second implementation manner: reduce the target reception parameter, and monitor the first channel occupancy indication used to indicate successful preemption of the channel on the unlicensed spectrum based on the target reception parameter after the reduction process.

其中，该目标接收参数可以根据实际需求进行选取，或者，该目标接收参数也可以由该终端默认设置，再或者，该目标接收参数还可以由网络配置。The target receiving parameter can be selected according to actual needs, or the target receiving parameter can also be set by the terminal by default, or the target receiving parameter can also be configured by the network.

也即是，在监听并接收第一信道占用指示过程中通常会涉及一些接收参数，可以选取一些目标接收参数，譬如，该目标接收参数可以包括但不限定于接收天线数或MIMO(Multiple-Input Multiple-Output，多输入多输出)阶数。然后，降低该目标接收参数，并基于降低处理后的目标接收参数监听并接收该第一信道占用指示，从而实现以低功率模式监听并接收。That is, in the process of monitoring and receiving the first channel occupancy indication, some receiving parameters are usually involved, and some target receiving parameters can be selected. For example, the target receiving parameters can include but not limited to the number of receiving antennas or MIMO (Multiple-Input Multiple-Output, multiple input multiple output) order. Then, the target receiving parameter is reduced, and the first channel occupancy indication is monitored and received based on the target receiving parameter after the reduction process, so as to realize monitoring and receiving in a low power mode.

步骤202：根据对该第一信道占用指示的监听结果，控制非连续接收DRX定时器的状态，该监听结果包括监听到该第一信道占用指示或未监听到该第一信道占用指示。Step 202: Control the state of the discontinuous reception DRX timer according to the monitoring result of the first channel occupancy indication, and the monitoring result includes whether the first channel occupancy indication is monitored or not.

作为一种示例，该DRX定时器包括DRX持续定时器、DRX非激活定时器、DRX下行重传定时器、DRX上行重传定时器和随机接入竞争解决定时器中的任一种或多种。As an example, the DRX timer includes any one or more of DRX duration timer, DRX inactive timer, DRX downlink retransmission timer, DRX uplink retransmission timer, and random access contention resolution timer .

终端根据监听到该第一信道占用指示和未监听到该第一信道占用指示的结果不同，控制DRX定时器处于不同的状态，从而使得终端能够在基站成功抢占到信道的情况下，成功被基站调度，并且不需要为终端配置更长的定时器时长，也不需要将为终端配置的DRX周期的时长缩小一定时长。The terminal controls the DRX timer to be in a different state according to the difference between the results of the first channel occupancy indication being monitored and the first channel occupancy indication not being monitored, so that the terminal can be successfully acquired by the base station when the base station successfully seizes the channel. Scheduling, and there is no need to configure a longer timer duration for the terminal, and there is no need to reduce the duration of the DRX cycle configured for the terminal by a certain duration.

在本申请实施例中，监听第一信道占用指示，由于该第一信道占用指示能够用于指示是否成功抢占到非授权频谱上的信道，因此，可以根据对该第一信道占用指示的监听结果，控制DRX定时器的状态，从而保证终端能够在信道占用时间内成功被调度。如此，不需要为终端配置更长的定时器时长，也不需要将为终端配置的DRX周期的时长缩小一定时长，在保证能够增加终端非连续接收的成功率的情况下，减小了终端的功耗。In the embodiment of the present application, the first channel occupancy indicator is monitored. Since the first channel occupancy indicator can be used to indicate whether the channel on the unlicensed spectrum is successfully occupied, it can be based on the monitoring result of the first channel occupancy indicator , Control the state of the DRX timer, so as to ensure that the terminal can be successfully scheduled within the channel occupation time. In this way, there is no need to configure a longer timer duration for the terminal, and there is no need to reduce the duration of the DRX cycle configured for the terminal by a certain duration. While ensuring that the success rate of discontinuous reception of the terminal can be increased, the terminal’s Power consumption.

请参考图3，该图3是根据另一示例性实施例示出的一种DRX定时器的控制方法流程图，该方法可以应用于上述图1所示实施环境中，主要由终端来执行，该方法可以包括如下几个实现步骤：Please refer to FIG. 3, which is a flowchart of a method for controlling a DRX timer according to another exemplary embodiment. The method can be applied to the implementation environment shown in FIG. 1, and is mainly executed by the terminal. The method can include the following implementation steps:

步骤301：监听用于指示成功抢占到非授权频谱上的信道的第一信道占用指示。Step 301: Monitor the first channel occupancy indication used to indicate that the channel on the unlicensed spectrum is successfully occupied.

其具体实现可以参见上文图2所示实施例中的步骤201，这里不再重复赘述。For specific implementation, refer to step 201 in the embodiment shown in FIG. 2 above, and details are not repeated here.

步骤302：当该监听结果包括监听到该第一信道占用指示时，若在第一时间段内确定该DRX定时器满足启动或重启条件，则启动或重启该DRX定时器，该第一时间段是以该第一信道占用指示的接收时刻为起始时刻、信道最大占用时间MCOT为持续时长的时间段。Step 302: When the monitoring result includes the first channel occupancy indication being monitored, if it is determined within the first time period that the DRX timer meets the start or restart conditions, start or restart the DRX timer, and the first time period It is a time period in which the receiving time of the first channel occupancy indication is the starting time, and the maximum channel occupancy time MCOT is the duration.

需要说明的是，这里以及下文所说的DRX定时器满足启动或重启条件，以及DRX定时器不满足启动或重启条件是根据目前已有的DRX机制来判断的，具体判断过程可以参见上文中对各个定时器的启动或重启条件的介绍部分。It should be noted that the DRX timer mentioned here and below meets the start or restart conditions, and the DRX timer does not meet the start or restart conditions are judged based on the existing DRX mechanism. For the specific judgment process, please refer to the above Introduction to the start or restart conditions of each timer.

作为一种示例，可以根据DRX配置参数确定该DRX定时器是否满足启动或重启条件，该DRX配置参数可以由基站配置给终端，该DRX配置参数可以用于指示DRX定时器在何时启动或者重启。示例性的，该DRX配置参数可以包括DRX周期的时长(包括长DRX周期和短DRX周期)、各个DRX定时器配置信息(比如包括各个DRX定时器的启动或重启时刻)、各个DRX定时器的持续时长等，另外，还可以包括DRX持续定时器的起始时刻配置，譬如，子帧偏移配置为0，时隙偏移配置为0等。As an example, it can be determined whether the DRX timer meets the start or restart condition according to the DRX configuration parameter. The DRX configuration parameter can be configured by the base station to the terminal, and the DRX configuration parameter can be used to indicate when the DRX timer is started or restarted. . Exemplarily, the DRX configuration parameters may include the duration of the DRX cycle (including the long DRX cycle and the short DRX cycle), the configuration information of each DRX timer (for example, including the start or restart time of each DRX timer), and the duration of each DRX timer The duration, etc., in addition, may also include the configuration of the start time of the DRX duration timer, for example, the subframe offset is configured to be 0, and the time slot offset is configured to be 0.

当该监听结果包括监听到该第一信道占用指示时，说明基站已经成功抢占到非授权频谱上的信道，在该种情况下，终端可以控制DRX定时器只在信道占用时间内启动或重启，为此，可以确定以第一信道占用指示为起始时刻、MCOT为持续时长的第一时间段，如果在该第一时间段内该DRX定时器满足启动或重启条件，则启动或重启该DRX定时器。When the monitoring result includes monitoring the first channel occupation indication, it indicates that the base station has successfully seized the channel on the unlicensed spectrum. In this case, the terminal can control the DRX timer to start or restart only during the channel occupation time. For this reason, the first time period with the first channel occupancy indication as the starting time and MCOT as the duration can be determined, and if the DRX timer meets the start or restart conditions within the first time period, the DRX is started or restarted Timer.

其中，在该第一时间段内该DRX定时器满足启动或重启条件可能包括两种情况：一种情况是，在该第一时间段之前的某个时刻该DRX定时器满足启动或重启条件，在该种情况下，只要接收到该第一信道占用指示就可以立马启动该DRX定时器；另一种情况是，在该第一时间段之前该DRX定时器不满足启动或重启条件，直到该第一时间段内的某个时刻该DRX定时器才满足启动或重启条件，在该种情况下，在该第一时间段内，只要确定DRX定时器满足启动或重启条件，即立马启动或重启该DRX定时器。Wherein, the DRX timer meeting the start or restart condition in the first time period may include two situations: one situation is that the DRX timer meets the start or restart condition at a certain time before the first time period, In this case, as long as the first channel occupancy indication is received, the DRX timer can be started immediately; in the other case, the DRX timer does not meet the start or restart conditions before the first time period until the At a certain moment in the first time period, the DRX timer meets the start or restart conditions. In this case, within the first time period, as long as the DRX timer meets the start or restart conditions, it starts or restarts immediately. The DRX timer.

进一步地，当该监听结果包括监听到该第一信道占用指示时，如果该DRX定时器为DRX 持续定时器，若在第一时间段内确定该DRX持续定时器不满足启动或重启条件，如果再次监听到第二信道占用指示且该DRX持续定时器满足启动或重启条件，当该第二信道占用指示的接收时刻与该DRX持续定时器满足启动或重启条件的时刻之间的时间间隔小于当前DRX周期的时长时，在第二时间段内启动或重启该DRX持续定时器，该第二时间段是以该第二信道占用指示的接收时刻为起始时刻、MCOT为持续时长的时间段。Further, when the monitoring result includes monitoring the first channel occupancy indication, if the DRX timer is a DRX duration timer, if it is determined within the first time period that the DRX duration timer does not meet the start or restart conditions, if The second channel occupation indication is heard again and the DRX persistence timer meets the start or restart condition, when the time interval between the moment when the second channel occupation indication is received and the moment when the DRX persistence timer meets the start or restart condition is less than the current When the duration of the DRX cycle is long, the DRX duration timer is started or restarted in a second time period, where the second time period is a time period in which the receiving time of the second channel occupancy indication is the starting time and the MCOT is the duration.

也即是，对于DRX持续定时器来说，如果在接收到第一信道占用指示后的信道占用时间内，该DRX持续定时器没有满足启动或者重启条件，则终端不启动该DRX持续定时器。等到终端下一次监听到第二信道占用指示，如果在第二时间段内该DRX持续定时器满足启动或重启条件，则判断该第二信道占用指示的接收时刻与该DRX定时器满足启动或重启条件的时刻之间的时间间隔是否小于当前DRX周期的时长，如果小于，则说明从DRX定时器满足启动或重启条件的时刻起至接收到第二信道占用指示的时刻为止没有超过一个DRX周期，此时可以在第二时间段内启动或重启DRX持续定时器。That is, for the DRX persistence timer, if the DRX persistence timer does not meet the start or restart condition within the channel occupation time after receiving the first channel occupation indication, the terminal does not start the DRX persistence timer. Wait until the terminal monitors the second channel occupancy indication next time, and if the DRX persistence timer meets the start or restart condition within the second time period, it is determined that the receiving time of the second channel occupancy indication and the DRX timer meet the start or restart Whether the time interval between the time of the condition is less than the duration of the current DRX cycle, if it is less, it means that there is no more than one DRX cycle from the moment when the DRX timer meets the start or restart condition to the moment when the second channel occupation indication is received, At this time, the DRX persistence timer can be started or restarted in the second time period.

需要说明的是，这里所说的在第二时间段内该DRX持续定时器满足启动或重启条件也包括两种情况：一种情况是，在第一时间段之后且在该第二时间段之前的某个时刻DRX持续定时器满足启动或重启条件；另一种情况是，在第一时间段之后且在该第二时间段之前，该DRX持续定时器不满足启动或重启条件，直到进入第二时间段之后的某个时刻，该DRX持续定时器才满足启动或重启条件。It should be noted that the DRX duration timer meeting the start or restart condition during the second time period mentioned here also includes two cases: one case is after the first time period and before the second time period The DRX persistence timer meets the start or restart conditions at a certain moment in time period; in another case, after the first time period and before the second time period, the DRX persistence timer does not meet the start or restart conditions until it enters the first time period. At a certain time after the second time period, the DRX duration timer meets the start or restart condition.

进一步地，当该监听结果包括监听到该第一信道占用指示时，如果该DRX定时器为DRX持续定时器，若在第一时间段内确定该DRX持续定时器不满足启动或重启条件，则当在该DRX持续定时器满足启动或重启条件之后的一个DRX周期内一直未接收到第二信道占用指示时，取消该DRX持续定时器满足启动或重启条件时所在的DRX周期内该DRX持续定时器的启动或重启。Further, when the monitoring result includes monitoring the first channel occupancy indication, if the DRX timer is a DRX persistence timer, if it is determined within the first time period that the DRX persistence timer does not meet the start or restart conditions, then When the second channel occupancy indication has not been received in a DRX cycle after the DRX persistence timer meets the start or restart conditions, cancel the DRX persistence timer in the DRX cycle where the DRX persistence timer meets the start or restart conditions. Start or restart the device.

也即是，对于DRX持续定时器来说，如果在第一时间段内未启动或重启，则当检测到该DRX持续定时器满足启动或重启条件时，从满足条件的该时刻起，如果在之后的一个DRX周期内一直没有接收到第二信道占用指示，说明在当前的DRX周期内，该DRX持续定时器始终无法启动或重启，此时，取消当前DRX周期内该DRX持续定时器的启动或重启，进入下一个DRX周期。That is, for the DRX persistence timer, if it is not started or restarted within the first time period, when it is detected that the DRX persistence timer meets the start or restart conditions, from the moment when the conditions are met, if The second channel occupancy indication has not been received in the following DRX cycle, indicating that the DRX persistence timer cannot be started or restarted in the current DRX cycle. At this time, the start of the DRX persistence timer in the current DRX cycle is cancelled Or restart and enter the next DRX cycle.

步骤303：当该监听结果包括未监听到该第一信道占用指示时，若确定该DRX定时器满足启动或重启条件，不启动或不重启该DRX定时器。Step 303: When the monitoring result includes that the first channel occupation indication is not monitored, if it is determined that the DRX timer meets the start or restart condition, the DRX timer is not started or restarted.

如果监听结果包括未监听到该第一信道占用指示，则说明基站没有发送第一信道占用指示，从而可以说明基站未成功抢占到非授权频谱上的信道，在该种情况下，即使确定该DRX 定时器满足启动或重启条件，也控制DRX定时器不启动或不重启。If the monitoring result includes that the first channel occupancy indication is not monitored, it means that the base station has not sent the first channel occupancy indication, which may indicate that the base station has not successfully seized the channel on the unlicensed spectrum. In this case, even if the DRX is determined When the timer meets the start or restart conditions, it also controls the DRX timer not to start or restart.

进一步地，控制该DRX定时器在信道占用时间内运行，在非信道占用时间内暂停运行。Further, the DRX timer is controlled to run during the channel occupancy time, and the operation is suspended during the non-channel occupancy time.

也即是说，在按照上述方式控制DRX定时器启动或重启的情况下，如果处于该第一时间段内，则控制该DRX定时器运行，在该第一时间段的结束时刻，终端挂起正在运行的DRX定时器，并在下一次进入信道占用时间内后恢复DRX定时器的运行，如此反复控制DRX定时器运行和暂停运行，直到在信道占用时间内DRX定时器超时。That is to say, in the case of controlling the start or restart of the DRX timer in the above manner, if it is within the first time period, control the DRX timer to run, and at the end of the first time period, the terminal hangs up The running DRX timer will resume the operation of the DRX timer after entering the channel occupation time next time, and control the DRX timer to run and suspend operation repeatedly in this way until the DRX timer expires within the channel occupation time.

进一步地，在该DRX定时器运行时间内监听PDCCH，在该DRX定时器暂停运行时间内不监听除用于传输信道占用指示之外的PDCCH。Further, the PDCCH is monitored during the running time of the DRX timer, and the PDCCH except for the transmission channel occupation indication is not monitored during the suspended running time of the DRX timer.

也就是说，只有该DRX定时器运行时，该终端才执行监听PDCCH的操作，如果DRX定时器没有运行，则该终端只监听用于传输信道占用指示的PDCCH，不监听其他PDCCH。进一步地，当利用DMRS作为信道占用指示时，在DRX定时器暂停运行时间内，该终端可以不监听PDCCH，只监听DMRS。That is, only when the DRX timer is running, the terminal performs the operation of monitoring the PDCCH. If the DRX timer is not running, the terminal only monitors the PDCCH used for the transmission channel occupation indication and does not monitor other PDCCHs. Further, when the DMRS is used as a channel occupancy indicator, the terminal may not monitor the PDCCH and only monitor the DMRS during the time when the DRX timer is suspended.

在上述实现方式中，控制DRX定时器只在信道占用时间内启动或重启，在非信道占用时间内不启动或不重启，并且，该DRX定时器只在信道占用时间内运行，在非信道占用时间内不运行，另外，UE在DRX定时器运行时监听PDCCH，在DRX定时器不运行时不监听除用于传输信道占用指示之外的PDCCH。采用该种方式，DRX定时器实际上只考虑信道占用时间的调度情况，如果信道占用时间没有任何调度，则只监听用于传输信道占用指示的PDCCH，如此也可以准确确定数据的调度情况，增加终端能够成功被调度的概率，并减小了终端的功耗，从而很好地兼顾了调度性能和终端省电的问题。另外，DRX定时器的实际运行时长可以反映基站能够给终端调度数据的时长。In the above implementation manner, the DRX timer is controlled to be started or restarted only during the channel occupation time, and not started or restarted during the non-channel occupation time, and the DRX timer only runs during the channel occupation time, and the DRX timer only runs during the channel occupation time. It does not run within the time period. In addition, the UE monitors the PDCCH when the DRX timer is running, and does not monitor the PDCCH except for the transmission channel occupation indication when the DRX timer is not running. In this way, the DRX timer actually only considers the scheduling of the channel occupancy time. If there is no scheduling for the channel occupancy time, only the PDCCH used to transmit the channel occupancy indication is monitored, so that the data scheduling can also be accurately determined, increasing The probability that the terminal can be successfully scheduled, and the power consumption of the terminal is reduced, so that the scheduling performance and the power saving of the terminal are well balanced. In addition, the actual running duration of the DRX timer can reflect the duration of the base station being able to schedule data for the terminal.

为了便于理解，接下来以图4为例对图3实施例提供的方案的具体实现进行举例说明。请参考图4，主要包括如下几个过程：For ease of understanding, the following takes FIG. 4 as an example to illustrate the specific implementation of the solution provided in the embodiment of FIG. 3. Please refer to Figure 4, which mainly includes the following processes:

1、终端以低功率模式监听第一信道占用指示，以根据对该第一信道占用指示的监听结果确定非授权频谱上的下行信道是否可用。如图4中的实线区域表示这段时间内非授权频谱上的下行信道可用；除了实线区域之外的区域表示这段时间内非授权频谱上的下行信道不可用。1. The terminal monitors the first channel occupancy indication in a low-power mode to determine whether the downlink channel on the unlicensed spectrum is available according to the monitoring result of the first channel occupancy indication. The solid line area in Figure 4 indicates that the downlink channel on the unlicensed spectrum is available during this period; the area other than the solid line area indicates that the downlink channel on the unlicensed spectrum is unavailable during this period.

2、在第一个DRX周期的起始时刻，由于非授权频谱上的下行信道不可用，此时终端不启动DRX持续定时器，等到终端接收到来自基站的第一信道占用指示的时刻，如果DRX持续定时器满足启动条件，则终端启动该DRX持续定时器，并且在这个信道占用时间内运行该DRX持续定时器。当这个信道占用时间结束后，终端暂停运行DRX持续定时器，一直到终端下一次接收到来自网络的第二信道占用指示的时刻，终端恢复运行DRX持续定时器，如此反复控制DRX持续定时器运行和暂停运行，直到在信道占用时间内DRX持续定时器超时。2. At the beginning of the first DRX cycle, because the downlink channel on the unlicensed spectrum is unavailable, the terminal does not start the DRX duration timer at this time, and waits until the terminal receives the first channel occupation indication from the base station, if If the DRX persistence timer meets the start condition, the terminal starts the DRX persistence timer, and runs the DRX persistence timer within the channel occupation time. When this channel occupancy time expires, the terminal suspends running the DRX persistence timer until the next time the terminal receives the second channel occupation indication from the network, the terminal resumes running the DRX persistence timer, and repeatedly controls the DRX persistence timer to run. And suspend operation until the DRX duration timer expires within the channel occupation time.

3、在DRX持续定时器运行期间，终端接收到指示调度下行初始传输的PDCCH后，终端启动DRX非激活定时器，并且DRX非激活定时器只在信道占用时间内运行，在每次信道占用时间结束的时刻，终端暂停运行DRX非激活定时器，一直到终端下一次接收到来自网络的信道占用指示的时刻，终端恢复运行DRX非激活定时器，直到在信道占用时间内DRX非激活定时器超时。3. During the operation of the DRX persistence timer, after the terminal receives the PDCCH indicating the scheduling of the initial downlink transmission, the terminal starts the DRX inactive timer, and the DRX inactive timer only runs during the channel occupation time, at each channel occupation time At the end, the terminal suspends running the DRX inactive timer until the next time the terminal receives a channel occupation indication from the network, the terminal resumes running the DRX inactive timer until the DRX inactive timer expires within the channel occupation time .

4、终端在PDCCH指示的资源上接收下行数据并对接收数据进行解码，如果解码失败，终端在完成针对这次下行传输的NACK反馈后，启动定时器DRX-HARQ-RTT-Timer。请参考图4，该DRX-HARQ-RTT-Timer超时后，由于非授权频谱上的下行信道不可用，因此终端不启动DRX下行重传定时器。等到下一次接收到来自网络的信道占用指示的时刻，终端启动该DRX下行重传定时器，并且该DRX下行重传定时器只在信道占用时间内运行，在每次信道占用时间结束的时刻，终端暂停运行DRX下行重传定时器，一直到终端再次接收到信道占用指示的时刻，恢复运行该DRX下行重传定时器，直到在信道占用时间内该DRX下行重传定时器超时。4. The terminal receives the downlink data on the resource indicated by the PDCCH and decodes the received data. If the decoding fails, the terminal starts the timer DRX-HARQ-RTT-Timer after completing the NACK feedback for this downlink transmission. Please refer to FIG. 4, after the DRX-HARQ-RTT-Timer expires, because the downlink channel on the unlicensed spectrum is unavailable, the terminal does not start the DRX downlink retransmission timer. When the next time it receives a channel occupation indication from the network, the terminal starts the DRX downlink retransmission timer, and the DRX downlink retransmission timer only runs during the channel occupation time. At the end of each channel occupation time, The terminal suspends running the DRX downlink retransmission timer until the terminal receives the channel occupation indication again, and resumes the DRX downlink retransmission timer until the DRX downlink retransmission timer expires within the channel occupation time.

需要说明的是，这里仅是以终端在PDCCH指示的资源上接收下行数据为例进行说明，当终端在PDCCH指示的资源上发送上行数据时，关于对DRX上行重传定时器的控制与上述对DRX下行重传定时器的控制同理，这里不再举例介绍。It should be noted that the description here is only taking the terminal receiving downlink data on the resources indicated by the PDCCH as an example. When the terminal sends uplink data on the resources indicated by the PDCCH, the control of the DRX uplink retransmission timer is the same as the above. The control of the DRX downlink retransmission timer is the same, and the description is not given here.

5、请参考图4，在第二个DRX周期的起始时刻，非授权频谱上的下行信道可用，如果DRX持续定时器满足重启条件，则终端重启DRX持续定时器，并且该DRX持续定时器只在信道占用时间内运行，在每次信道占用时间结束的时刻，终端暂停运行该DRX持续定时器，一直到终端下一次接收到来自网络的信道占用指示，终端恢复运行DRX持续定时器，直到在信道占用时间内DRX持续定时器超时。5. Please refer to Figure 4. At the beginning of the second DRX cycle, the downlink channel on the unlicensed spectrum is available. If the DRX persistence timer meets the restart condition, the terminal restarts the DRX persistence timer, and the DRX persistence timer Only run during the channel occupation time. At the end of each channel occupation time, the terminal suspends running the DRX duration timer until the terminal receives the channel occupation indication from the network next time, and the terminal resumes running the DRX duration timer until The DRX duration timer expires during the channel occupation time.

按照上述实现方式，可以继续在第二DRX周期内、或更多的DRX周期内控制其他DRX定时器的状态，这里不再重复赘述。According to the foregoing implementation manner, it is possible to continue to control the state of other DRX timers in the second DRX cycle or in more DRX cycles, which will not be repeated here.

请参考图5，该图5是根据另一示例性实施例示出的一种DRX定时器的控制方法流程图，该方法可以应用于上述图1所示实施环境中，主要由终端来执行，该方法可以包括如下几个实现步骤：Please refer to FIG. 5, which is a flowchart of a method for controlling a DRX timer according to another exemplary embodiment. The method can be applied to the implementation environment shown in FIG. 1 and is mainly executed by the terminal. The method can include the following implementation steps:

步骤501：监听用于指示成功抢占到非授权频谱上的信道的第一信道占用指示。Step 501: Monitor the first channel occupancy indication used to indicate that the channel on the unlicensed spectrum is successfully occupied.

其具体实现可以参见上述图2所示实施例中的步骤201，这里不再重复赘述。For specific implementation, refer to step 201 in the embodiment shown in FIG. 2 above, and details are not repeated here.

需要说明的是，在这里，终端可以根据目前的DRX机制来确定各个DRX定时器的启动或重启时机，也就是说，DRX定时器的启动或重启时机可能处于信道占用时间外，也可能处于信道占用时间内。当然，对于DRX非激活定时器来说，启动或重启时机一定是在信道占用时间内。It should be noted that, here, the terminal can determine the start or restart timing of each DRX timer according to the current DRX mechanism, that is, the start or restart timing of the DRX timer may be outside the channel occupation time or may be in the channel Occupy time. Of course, for the DRX inactive timer, the start or restart time must be within the channel occupation time.

在本实施例中，可以根据对该第一信道占用指示的监听结果控制DRX定时器的运行状态，根据监听结果不同，具体实现可以包括如下步骤502和步骤503。In this embodiment, the running state of the DRX timer can be controlled according to the monitoring result of the first channel occupancy indication. According to different monitoring results, the specific implementation may include the following

steps

502 and 503.

步骤502：当该监听结果包括监听到该第一信道占用指示时，如果在第一时间段内该DRX定时器处于运行状态，则暂停运行该DRX定时器，该第一时间段是以该第一信道占用指示的接收时刻为起始时刻、信道最大占用时间MCOT为持续时长的时间段。Step 502: When the monitoring result includes the monitoring of the first channel occupancy indication, if the DRX timer is running in the first time period, the DRX timer is suspended, and the first time period is based on the first time period. The receiving moment of a channel occupancy indication is the start moment, and the channel maximum occupancy time MCOT is a time period of duration.

当该监听结果包括监听到该第一信道占用指示时，说明基站已经成功抢占到非授权频谱上的信道，如果DRX定时器处于运行状态，则暂停运行该DRX定时器，也就是说，在接收到该第一信道占用指示的时刻就暂停运行该DRX定时器，从而使得DRX定时器在信道占用时间内暂停运行。When the monitoring result includes monitoring the first channel occupancy indication, it means that the base station has successfully preempted the channel on the unlicensed spectrum. If the DRX timer is running, the DRX timer will be suspended, that is, the At the moment when the first channel occupation indication is reached, the DRX timer is suspended, so that the DRX timer is suspended during the channel occupation time.

步骤503：当该监听结果包括未监听到该第一信道占用指示时，如果该DRX定时器处于暂停运行状态，则恢复该DRX定时器的运行。Step 503: When the monitoring result includes that the first channel occupation indication is not monitored, if the DRX timer is in a suspended operation state, resume the operation of the DRX timer.

当该监听结果包括未监听到该第一信道占用指示时，说明基站未成功抢占到非授权频谱上的信道，如果DRX定时器处于暂停运行状态，则控制该DRX定时器继续运行，也就是说，在信道占用时间结束的时刻，恢复DRX定时器的运行，使得DRX定时器在非信道占用时间内运行。When the monitoring result includes that the first channel occupancy indication is not monitored, it means that the base station has not successfully seized the channel on the unlicensed spectrum. If the DRX timer is in the suspended state, the DRX timer is controlled to continue running, that is to say , At the moment when the channel occupancy time ends, resume the operation of the DRX timer, so that the DRX timer runs within the non-channel occupancy time.

进一步地，在该DRX定时器暂停运行时间内监听PDCCH，在DRX定时器运行时间内不监听除用于传输信道占用指示之外的PDCCH。Further, the PDCCH is monitored during the suspended running time of the DRX timer, and the PDCCH except for the transmission channel occupation indication is not monitored during the running time of the DRX timer.

由于DRX定时器在信道占用时间内暂停运行，在非信道占用时间内恢复运行，因此，终端在该DRX定时器暂停运行时间内监听PDCCH，在DRX定时器运行时间内不监听除用于传输信道占用指示之外的PDCCH意味着，在信道占用时间内监听PDCCH，在非信道占用时间内不监听除用于传输信道占用指示之外的PDCCH。进一步地，当利用DMRS作为信道占用指示时，在DRX定时器运行时间内，该终端可以不监听PDCCH，只监听DMRS。Since the DRX timer is suspended during the channel occupancy time and resumes operation during the non-channel occupancy time, the terminal monitors the PDCCH during the DRX timer suspension time, and does not monitor the DRX timer except for the transmission channel The PDCCH other than the occupied indication means that the PDCCH is monitored during the channel occupation time, and the PDCCH except for the transmission channel occupation indication is not monitored during the non-channel occupation time. Further, when the DMRS is used as the channel occupancy indicator, during the running time of the DRX timer, the terminal may not monitor the PDCCH, but only monitor the DMRS.

如此，可以使得终端可以在基站占用信道的时间内一直监听调度信息，而不会在基站占用信道的时间内回到睡眠状态，不仅可以保证终端能够成功被基站调度，且节省了终端的功耗。In this way, the terminal can always monitor the scheduling information while the base station is occupying the channel without going back to sleep while the channel is occupied by the base station. This not only ensures that the terminal can be successfully scheduled by the base station, but also saves the power consumption of the terminal. .

为了便于理解，接下来以图6为例对图5实施例提供的方案的具体实现进行举例说明。请参考图6，主要包括如下几个过程：For ease of understanding, the following takes FIG. 6 as an example to illustrate the specific implementation of the solution provided in the embodiment of FIG. 5. Please refer to Figure 6, which mainly includes the following processes:

1、终端以低功率模式监听第一信道占用指示，根据该第一信道占用指示的监听结果确定非授权频谱上的下行信道是否可用。如图6所示，图中的实线区域表示这段时间内非授权频谱上的下行信道可用，除了实线区域之外的区域表示这段时间内非授权频谱上的下行信道不可用。1. The terminal monitors the first channel occupancy indication in a low power mode, and determines whether the downlink channel on the unlicensed spectrum is available according to the monitoring result of the first channel occupancy indication. As shown in Figure 6, the solid line area in the figure indicates that the downlink channel on the unlicensed spectrum is available during this period, and the area other than the solid line area indicates that the downlink channel on the unlicensed spectrum is unavailable during this period.

2、在第一个DRX周期的起始时刻，由于非授权频谱上的下行信道不可用，假设DRX持续定时器满足启动条件，终端启动并运行该DRX持续定时器。当终端接收到来自网络的第一信道占用指示时，暂停运行该DRX持续定时器，一直到信道占用时间的结束时刻，终端恢复运行该DRX持续定时器，并在再次接收到第二信道占用指示时，暂停运行该DRX持续定时器，如此反复控制DRX持续定时器运行和暂停运行，直到在非信道占用时间内该DRX持续定时器超时。2. At the beginning of the first DRX cycle, since the downlink channel on the unlicensed spectrum is unavailable, assuming that the DRX persistence timer meets the starting condition, the terminal starts and runs the DRX persistence timer. When the terminal receives the first channel occupancy indication from the network, the DRX persistence timer is suspended until the end of the channel occupancy time, the terminal resumes running the DRX persistence timer, and receives the second channel occupancy indication again At this time, the DRX continuation timer is suspended, and the DRX continuation timer is controlled to run and suspend the operation repeatedly until the DRX continuation timer expires within the non-channel occupation time.

3、在DRX持续定时器运行期间，当终端接收到指示调度下行初始传输的PDCCH后，启动DRX非激活定时器，由于UE启动DRX非激活定时器的时刻，该非授权频谱上的下行信道可用，因此UE启动后立即暂停运行该DRX非激活定时器，一直到信道占用时间结束的时刻，UE恢复运行DRX非激活定时器。终端下一次接收到来自网络的信道占用指示的时刻，又暂停运行DRX非激活定时器。等到信道占用时间的结束时刻恢复运行DRX非激活定时器，一直到在非信道占用时间内DRX非激活定时器超时。3. During the operation of the DRX continuous timer, when the terminal receives the PDCCH indicating the scheduling of the initial downlink transmission, it starts the DRX inactive timer. Since the UE starts the DRX inactive timer, the downlink channel on the unlicensed spectrum is available Therefore, the UE immediately suspends running the DRX inactivation timer after starting, until the time when the channel occupation time ends, the UE resumes running the DRX inactivation timer. The next time the terminal receives the channel occupation indication from the network, it suspends the DRX inactive timer. Wait until the end of the channel occupancy time to resume the DRX inactivation timer, until the DRX inactivation timer expires within the non-channel occupancy time.

4、终端在PDCCH指示的资源上接收下行数据并对接收数据进行解码，如果解码失败，终端在完成针对这次下行传输的NACK反馈后，启动定时器drx-HARQ-RTT-TimerDL。drx-HARQ-RTT-TimerDL超时后，终端启动DRX下行重传定时器，并且重传定时器只在非信道占用时间内运行。在每次终端接收到来自网络的信道占用指示的时刻，终端暂停运行DRX下行重传定时器，等到该信道占用时间的结束时刻终端恢复运行DRX下行重传定时器，一直到在非信道占用时间内DRX下行重传定时器超时。4. The terminal receives the downlink data on the resource indicated by the PDCCH and decodes the received data. If the decoding fails, the terminal starts the timer drx-HARQ-RTT-TimerDL after completing the NACK feedback for this downlink transmission. After drx-HARQ-RTT-TimerDL expires, the terminal starts the DRX downlink retransmission timer, and the retransmission timer only runs during non-channel occupation time. Each time the terminal receives a channel occupation indication from the network, the terminal suspends running the DRX downlink retransmission timer, and waits until the end of the channel occupation time, the terminal resumes running the DRX downlink retransmission timer, until the non-channel occupation time The internal DRX downlink retransmission timer expired.

5、在第二个DRX周期的起始时刻，终端重启DRX持续定时器，并且DRX持续定时器只在非信道占用时间内运行。请参考图6，由于UE启动DRX持续定时器的时刻非授权频谱上的下行信道可用，因此终端启动后立即暂停DRX持续定时器，一直到信道占用时间结束的时刻，终端恢复运行DRX持续定时器。在终端下一次接收到来自网络的信道占用指示的时刻，又暂停运行DRX持续定时器。等到这次信道占用时间的结束时刻终端恢复运行DRX持续定时器，一直到在非信道占用时间内DRX持续定时器超时。5. At the beginning of the second DRX cycle, the terminal restarts the DRX persistence timer, and the DRX persistence timer only runs during non-channel occupation time. Please refer to Figure 6, because the downlink channel on the unlicensed spectrum is available at the moment when the UE starts the DRX persistence timer, the terminal immediately suspends the DRX persistence timer after it is started. The terminal resumes the DRX persistence timer when the channel occupation time ends . At the time when the terminal receives the channel occupancy indication from the network next time, the DRX continuous timer is suspended again. Wait until the end of the channel occupancy time, the terminal resumes running the DRX duration timer until the DRX duration timer expires during the non-channel occupancy time.

按照上述实现方式，可以在第二DRX周期内、或更多的DRX周期内控制其他DRX定时器的状态，这里不再重复赘述。According to the foregoing implementation manner, the state of other DRX timers can be controlled in the second DRX cycle or in more DRX cycles, which will not be repeated here.
