相关申请的交叉引用
本申请主张在2020年2月10日在中国提交的中国专利申请号No.202010085307.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域，特别涉及一种非连续接收处理方法、终端、装置以及介质。
背景技术
相关技术中的蜂窝网络通信，终端和网络侧设备之间通过Uu接口进行上/下行数据和控制信息的传输。下面对蜂窝通信系统的非连续接收(Discontinuous Reception，DRX)机制进行简要说明。
在基于共享信道的移动通信系统中，例如长期演进(Long Term Evolution，LTE)中，上下行数据的传输由基站(eNB)调度器负责控制，当调度器确定调度某用户时，将通过控制信道通知终端在何种资源上发送或接收数据。终端，例如用户设备(User Equipment，UE)监听控制信道，当检测到包含自己的调度信息时，根据控制信道上的指示完成数据的发送(上行)或接收(下行)。在激活状态下，由于终端不确定eNB何时对其进行调度，因此一种常见的工作模式为，终端连续监听控制信道，对每个包含其下行调度控制信道的子帧都进行解析，以判断是否被调度。这种工作方式在终端数据量较大，可能被频繁调度的情况下能获得较高的效率。然而对某些业务而言，数据的到达频率较低，导致终端被调度的次数也较小，如果终端仍然连续监听控制信道，无疑会增加其耗电量。为了解决耗电问题，蜂窝网络通信系统采用了DRX工作模式，在这种工作模式下，终端周期性的对控制信道进行监听，因而达到节电的目的。
相关技术的不足在于，终端在进行直接通信接口通信时，无法实现直接通信接口的节电。

具体实施方式
申请人在公开过程中注意到：
图1为蜂窝通信网络示意图，如图所示，相关技术中的蜂窝网络通信，终端和网络侧设备之间通过Uu接口进行上/下行数据和控制信息的传输。
下面对DRX基本原理简要说明如下：
图2为DRX过程示意图，DRX的基本原理如图2所示。其中On duration(持续时间)表示UE监听控制信道的时间段，其间射频通道打开，并连续监听控制信道；除去On duration之外的其它时间，UE处于Sleep(睡眠)状态，其射频链路将被关闭，不再监听控制信道，以达到省电的目的。On Duration都是周期性出现(Cycle)，具体周期由eNB配置实现。
蜂窝网络的DRX机制考虑了数据业务的到达模型，即数据分组的到达是突发的(可以理解为，一旦有数据分组到达，那么会在较短时间内连续到达较多的分组)。为了适应这种业务到达特点，LTE DRX过程采用了多种定时器，并与混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)过程相结合，以期达到更好的节电性能。
下面对DRX相关定时器进行简要说明。
drx-onDurationTimer(DRX持续监听定时器)：UE周期性醒来监听控制信道的时间，如图2所示。
Short DRX cycle Timer(DRX短周期定时器)：为了更好的配合数据业务到达的特点，蜂窝网络通信系统支持配置两种DRX cycle：long cycle(长周期)和short cycle(短周期)。两种cycle的on duration timer相同，但sleep的时间不一样。在short cycle中，sleep时间相对更短，UE可以更快地再次监听控制信道。Long cycle是必须配置的，并且是DRX过程的初始状态；short cycle是可选的。short DRX cycle timer设置了采用short cycle持续的时间。Short cycle timer超时后，UE将使用Long cycle。
drx-InactivityTimer(DRX非激活定时器)：配置了DRX后，当UE在允许监听控制信道的时间内Active Time(激活期)收到HARQ初始传输的控制信令时打开该定时器，在该定时器超时之前，UE连续监听控制信道。如果在drx-InactivityTimer超时前，UE收到HARQ初始传输的控制信令，将终止并重新启动drx-InactivityTimer。
HARQ RTT Timer(HARQ往返时延定时器；RTT：往返时延，Round Trip Time)：分为drx-HARQ-RTT-TimerDL(HARQ往返时延定时器下行)和drx-HARQ-RTT-TimerUL(HARQ往返时延定时器上行)，目的是使UE有可能在下次重传到来前不监听控制信道，达到更好的节电效果。以下行为例，UE相关进程的物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输之后的第一个符号启动，将打开此定时器。如果对应HARQ进程中的数据在前一次HARQ传输后解码不成功(UE反馈NACK)，在DL HARQ RTT Timer超时后，UE打开drx-RetransmissionTimerDL。如果对应HARQ进程中的数据在前一次HARQ传输后解码成功(UE反馈ACK)，在drx-HARQ-RTT-TimerDL定时器超时后，UE不启动drx-RetransmissionTimerDL。如果当前只有drx-HARQ-RTT-TimerDL运行，UE不监听控制信道。
HARQ retransmission Timer(HARQ重传定时器)：分为drx-RetransmissionTimerDL(下行DRX重传定时器)或者drx-RetransmissionTimerUL(上行DRX重传定时器)。以下行为例，在DL HARQ retransmission Timer运行期间，UE监听控制信令，等待对应HARQ进程的重传调度。
DRX下Active time定义如下：
通过上述过程可以看出，在On duration Timer、HARQ retransmission Timer和Inactivity Timer中，有任何一个定时器正在运行，UE都将监听控制信道。UE监听控制信道的时间又称为Active Time。在LTE系统中Active Time除了受DRX timer的影响外还有其它因素影响，LTE Rel-8 UE的Active Time包括如下时间：
drx-onDurationTimer或者drx-InactivityTimer或者drx-RetransmissionTimerDL或者drx-RetransmissionTimerUL或者ra-ContentionResolutionTimer运行的时间；
UE发送上行调度请求(Scheduling Request，SR)后等待基站发送物理层下行控制信道(Physical Downlink Control Channel，PDCCH)的时间；
非竞争随机接入UE接收到随机接入响应(Random Access Response，RAR) 后等待小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)调度的PDCCH的时间。

[(SFN*10)+subframe number]modulo(shortDRX-Cycle)＝(drxStartOffset)
modulo(shortDRX-Cycle)；
对于long DRX cycle，onduration计算公式如下：

longDRX-Cycle：长DRX周期；
drxStartOffset：无线资源控制(Radio Resource Control，RRC)信令配置的一个偏移值。
下面对直接通信进行说明。
直接通信是指邻近的终端可以在近距离范围内通过直接通信链路(也称为Sidelink)进行数据传输的方式。Sidelink链路对应的无线接口称为直接通信接口，也称为Sidelink接口。图3为Sidelink发现/通信示意图。
相关技术中的无线通信系统的DRX只适用于终端和网络之间的Uu接口，直接通信接口尚无DRX机制，也就意味着直接通信接口无法节电。对于直接通信接口，相关技术中不支持任何节电机制，因此终端耗电量会比较快，用户体验不好。因此需要在直接通信接口引入节电机制，一种可能的方式就是在直接通信接口引入DRX机制，但是相关技术中在直接通信接口如何实现DRX尚没有公开的方案。
也即，相关技术的不足在于，终端在进行直接通信接口通信时，一直保持激活状态，无法实现直接通信接口的节电。
基于此，本公开给出了一种直接通信接口的DRX配置的使用方案。通过 该方法，可以实现直接通信接口的DRX，从而使得直接通信终端更好的节电。
下面结合附图对本公开的具体实施方式进行说明。
在说明过程中，将分别从直接通信中的直接通信终端与该直接通信终端的直接通信对端两个角度进行说明，然后还将给出二者配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当终端与对端分开实施时，其也各自解决自身一侧的问题，而二者结合使用时，会获得更好的技术效果。
