DRX
出于终端节电的考虑，目前的***均支持DRX传输机制。DRX主要的原理是通过半静态的配置来实现在时域上的不连续接收信号。在没有数据传输的时候，可以通过停止接收PDCCH(此时会停止PDCCH盲检)来降低功耗，从而提升电池使用时间。
比如在LTE***中，配置DRX方法是给连接态的终端配置一个DRX周期(DRXcycle)。如图2所示，DRX周期由激活时间(Active Time)和非激活时间(Inactive Time)组成，其中，在激活时间内，终端监听并接收PDCCH(激活期)；在非激活时间内，终端不接收PDCCH以减少功耗(休眠期)。另外，寻呼消息的传输属于一种空闲态的DRX机制，此时DRX周期为寻呼消息的周期。
激活时间和非激活时间按照以下方式形成：时间被划分成一个个连续的DRX周期。每个DRX周期开始进入DRX ON状态，在DRX ON时终端会按照配置的监测时机(Monitoring Occasion，MO)检测PDCCH。当终端检测到PDCCH时，启动或刷新非激活定时器(Inactivity Timer)。如果DRX ON未结束或者Inactivity Timer未结束，终端就处在激活时间。处在激活时间的终端需要检测PDCCH。
5G NR也沿用了LTE的节能机制，其定义的DRX配置方法继承了LTE的DRX配置。

跨时隙(Cross-slot)调度的节能
在5G以及LTE演进项目中，讨论DRX的增强机制。其中一种新的节能机制为跨时隙调度。其基本原理如图3所示。PDCCH配置成周期检测的(图3以PDCCH周期为2个时隙为例)，然而，比较普遍的一种情况是多数的PDCCH检测机会上并没有检测到数据调度，但是终端必须在PDCCH之后缓存数据。当实现跨时隙调度后，终端免去了PDCCH后的缓存环节，可以在PDCCH之后立即关闭射频模块。图3中的K0代表PDCCH所在的时隙与被调度的物理下行共享信道(Physical Downlink SharedChannel，PDSCH)所在的时隙的偏移值。
通过引入跨时隙调度使得终端的功耗降低，但是需要引入一种机制让网络通知终端进入跨时隙调度的状态。可以考虑直接通过PDCCH通知终端需要进入的跨时隙调度状态。
DRX机制配置较复杂，有一定的配置信令代价。DRX机制是半静态配置有较大的灵活性限制。采用PDCCH直接指示终端进入跨时隙调度状态的节能方式，可以更好地适应动态的调度变化，比DRX配置更灵活。
通过PDCCH指示跨时隙调度状态的机制，需要考虑如下问题：
1)PDCCH存在一定的漏检概率。一旦终端丢失网络所发送的用于指示跨时隙调度状态的PDCCH，会发生终端和网络对跨时隙调度状态理解不一致的问题。
2)当终端接收到用于指示跨时隙调度状态的节能指示信号(如PDCCH)时，终端需要一定的转换时间转换到所指示的跨时隙调度状态。
3)如果用于指示跨时隙调度状态的节能指示信号和DRX配置结合使用，用于指示跨时隙调度状态的节能指示信号可使用专用控制信道(即专用物理层信号)在DRX ON之前发送。此外，当DRX ON之前的节能指示信号(如专用控制信道)和DRX ON之内的节能指示信号(如PDCCH)同时存在时，需要定义相应的处理机制。
基于此，提出了本申请实施例的以下技术方案，可以实现跨时隙调度的节能功能。 需要说明的是，本申请实施例的技术方案还可以扩展到用于限制终端接收数据的MIMO传输层数，从而实现节能功能。以下对本申请实施例的技术方案进行详细说明。
图4为本申请实施例提供的控制通信状态的方法的流程示意图，如图4所示，所述控制通信状态的方法包括以下步骤：
步骤401：网络设备向终端发送PDCCH，终端在第一时隙接收网络设备发送的PDCCH，所述PDCCH携带第一指示信息，所述第一指示信息用于指示第一通信状态。
本申请实施例中，所述网络设备可以是基站，例如gNB，eNB等。
本申请实施例中，所述PDCCH也可以称为节能指示信号或节能调度信号。所述PDCCH携带第一指示信息，所述第一指示信息用于指示终端需要进入的第一通信状态，该第一通信状态可以是第一跨时隙调度状态或第一MIMO传输层数状态。
本申请实施例中，所述PDCCH携带第一指示信息，可以通过以下方式实现：在PDCCH中增加第一指示信息对应的比特位，通过该比特位来指示所述第一通信状态。
本申请实施例中，所述PDCCH还携带以下至少之一：数据信道的频域调度信息、数据信道的时域调度信息、调制编码策略(Modulation and Coding Scheme，MCS)指示信息、功控信息、信道状态信息(Channel State Information，CSI)触发信息、带宽部分(Band Width Part，BWP)切换指示信息。其中，数据信道包括以下至少之一：物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。
步骤402：所述终端根据所述第一指示信息，在第二时隙进入所述第一通信状态，所述第二时隙位于所述第一时隙之后。
本申请实施例中，考虑到当终端接收到PDCCH时，需要一定的转换时间转换到PDCCH所指示的第一通信状态，因而，终端在第一时隙接收到PDCCH后，在第二时隙进入所述PDCCH所指示的第一通信状态。以下结合不同的应用场景对本申请实施例的技术方案进行说明。
Figure PCTCN2020090082-appb-000003
场景一：
所述第一通信状态为第一跨时隙调度状态；所述终端将所述第一跨时隙调度状态与所述终端当前所处的第二跨时隙调度状态进行比较；若所述第一跨时隙调度状态与所述第二跨时隙调度状态不同，则所述终端在第二时隙进入所述第一跨时隙调度状态。
举个例子：UE在slot n接收网络设备发送的PDCCH。通过PDCCH中的N比特(bit)用于指示第一跨时隙调度状态，比如PDCCH中的2bit用于指示第一跨时隙调度状态。UE将PDCCH中指示的第一跨时隙调度状态和UE当前的第二跨时隙调度状态进行比较，如果不同，则UE在slot n+x进入PDCCH所指示的第一跨时隙调度状态。这里，UE当前的第二跨时隙调度状态是指UE在slot n对应的跨时隙调度状态。
本申请实施例中，所述第二时隙与所述第一时隙之间具有x个时隙的偏移，x为正整数。进一步，所述x的取值为a和S C中的最大值，所述a为常数，所述S C为所述终端当前所处的第二跨时隙调度状态对应的时隙偏移。
举个例子：x＝MAX(a，S C)。其中，S C为UE当前所处的第二跨时隙调度状态对应的时隙偏移(slot offset)，a为常数(如a＝1)。需要说明的是，跨时隙调度状态对应的时隙偏移是指如图3所示的K0，即：PDCCH调度的数据信道所在时隙与该PDCCH所在时隙的偏移。
本申请实施例中，所述第一指示信息包括N个比特位，N为正整数，所述N个比特位的不同取值用于表示不同的第一跨时隙调度状态，所述第一跨时隙调度状态与所述N个比特位的取值之间的对应关系由高层信令配置。这里，高层信例如是RRC信令。
举个例子：N＝2，通过2比特指示第一跨时隙调度状态，其中，“00”表示跨时隙调度状态1，其对应的时隙偏移为0，即：最小跨0个时隙进行调度，也就是S C＝0(允许同时隙调度)。“01”表示跨时隙调度状态2，其对应的时隙偏移为1，即：最小跨1个时隙进行调度，也就是S C＝1。“10”表示跨时隙调度状态3，其对应的时隙偏移为2，即：最小跨2个时隙进行调度，也就是S C＝2。“11”表示跨时隙调度状态4，其对应的时隙偏移为3，即：最小跨3个时隙进行调度，也就是S C＝3。需要说明的是，本申请实施例中的跨时隙调度状态对应的时隙偏移，是指跨时隙调度状态对应的最小时隙偏移。
本申请实施例中，所述N个比特位的取值由高层信令配置的PUSCH的跨时隙调度状态数和PDSCH的跨时隙调度状态数确定。具体地，若高层信令未配置所述PUSCH的跨时隙调度状态数和所述PDSCH的跨时隙调度状态数，则所述N比特位的取值为0；若高层信令配置所述PUSCH的跨时隙调度状态数和/或所述PDSCH的跨时隙调度状态数，则所述N比特位的取值为1。
这里，高层信令可以对PUSCH的跨时隙调度状态数和PDSCH的跨时隙调度状态数分别进行配置，或者，高层信令也可以选择仅配置PUSCH的跨时隙调度状态数或者仅配置PDSCH的跨时隙调度状态数，或者，高层信令也可以对PUSCH的跨时隙调度状态数和PDSCH的跨时隙调度状态数都不配置。
需要说明的是，PDSCH的跨时隙调度状态数用于确定PDSCH的第一时隙偏移，PUSCH的跨时隙调度状态数用于确定PUSCH的第二时隙偏移。
本申请实施例中，所述第一指示信息指示的所述第一跨隙时调度状态对应的时隙偏移有两种，分别是PDSCH对应的时隙偏移(称为第一时隙偏移)和PUSCH对应的时隙偏移(称为第二时隙偏移)，其中，所述PDSCH的第一时隙偏移和所述PUSCH的第二时隙偏移的取值不同。
进一步，所述PDSCH的第一时隙偏移和所述PUSCH的第二时隙偏移，可以通过以下两种方式进行配置：
1)每个所述第一跨时隙调度状态对应一组时隙偏移，所述一组时隙偏移包括PDSCH的第一时隙偏移和PUSCH的第二时隙偏移。例如：所述第一跨时隙调度状态通过2比特表示，任意一种2比特的取值可以对应下列两个时隙偏移的组合：
PDCCH调度的PDSCH相对于该PDCCH的时隙偏移(即第一时隙偏移)；
PDCCH调度的PUSCH相对于该PDCCH的时隙偏移(即第二时隙偏移)。
2)每个所述第一跨时隙调度状态对应一个时隙偏移，所述一个时隙偏移为PDSCH的第一时隙偏移或者为PUSCH的第二时隙偏移。例如：所述第一跨时隙调度状态通过2比特表示，任意一种2比特的取值可以对应下列其中一种时隙偏移：
PDCCH调度的PDSCH相对于该PDCCH的时隙偏移(即第一时隙偏移)；
PDCCH调度的PUSCH相对于该PDCCH的时隙偏移(即第二时隙偏移)。
即PDSCH和PUSCH对应的时隙偏移是独立配置的。
在一可选方式中，若高层信令配置所述第一跨时隙调度状态的取值，则所述第一跨时隙调度状态对应的一个时隙偏移的取值为所述第一跨时隙调度状态的取值；若高层信令未配置所述第一跨时隙调度状态的取值，则所述第一跨时隙调度状态对应的一个时隙偏移的取值为一常数值，例如常数值为0，代表所述第一跨时隙调度状态是时隙内调度。
对于PUSCH来说，PUSCH的第一时隙偏移的取值可以通过以下方式确定：
若高层信令配置所述第一跨时隙调度状态的取值，则所述PUSCH的第一时隙偏移的取值为所述第一跨时隙调度状态的取值；若高层信令未配置所述第一跨时隙调度状态的取值，则所述PUSCH的第一时隙偏移的取值为一常数值，例如常数值为0。
对于PDSCH来说，PDSCH的第一时隙偏移的取值可以通过以下方式确定：
若高层信令配置所述第一跨时隙调度状态的取值，则所述PDSCH的第一时隙偏移的取值为所述第一跨时隙调度状态的取值；若高层信令未配置所述第一跨时隙调度状态的取值，则所述PDSCH的第一时隙偏移的取值为一常数值，例如常数值为0。
本申请实施例还提供一种容错机制，具体地：
1)所述终端确定第一PDSCH的时域调度信息和所述终端当前所处的第二跨时隙调度状态不符的情况下，所述终端向所述网络设备发送负反馈消息，所述第一PDSCH是指所述终端在所述第一时隙接收到的所述PDCCH调度的PDSCH。
这里，若所述第一PDSCH的时域调度信息对应的时隙偏移小于所述终端当前所处的第二跨时隙调度状态对应的时隙偏移，则所述终端确定所述第一PDSCH的时域调度信息和所述终端当前所处的第二跨时隙调度状态不符。
举个例子：当UE在slot n接收到的PDCCH，该PDCCH调度的PDSCH的时域调度信息和UE当前所处的第二跨时隙调度状态不符时，UE反馈NACK给网络设备。其中，不符的判断条件至少包括：PDCCH调度的PDSCH的时域调度信息的时隙偏移小于S C。需要说明的是，PDCCH调度的PDSCH的时域调度信息的时隙偏移小于S C，会导致UE无法接收PDSCH，UE期望接收时隙偏移大于等于S C的PDSCH，因此，UE向网络设备反馈NACK。
2)所述终端确定第一PUSCH的时域调度信息和所述终端当前所处的第二跨时隙调度状态不符的情况下，所述终端不传输所述第一PUSCH给所述网络设备，所述第一PUSCH是指所述终端在所述第一时隙接收到的所述PDCCH调度的PUSCH。
这里，若所述第一PUSCH的时域调度信息对应的时隙偏移小于所述终端当前所处的第二跨时隙调度状态对应的时隙偏移，则所述终端确定所述第一PUSCH的时域调度信息和所述终端当前所处的第二跨时隙调度状态不符。
举个例子：当UE在slot n接收到的PDCCH，该PDCCH调度的PUSCH的时域调度信息和UE当前所处的第二跨时隙调度状态不符时，UE不传输该PDCCH调度的PUSCH给网络设备。其中，不符的判断条件至少包括：PDCCH调度的PUSCH的时域调度信息的时隙偏移小于S C。
本申请实施例中，当PDCCH调度的数据信道(PUSCH或PDSCH)的时域调度信息与终端当前的第二跨时隙调度状态不符时，终端忽略该数据信道的调度，但是该PDCCH中的其他域，如第一指示信息、功控信息等仍然有效。
本申请实施例中，所述终端在未收到所述第一指示信息之前，处于默认跨时隙调度状态，所述默认跨时隙调度状态对应的时隙偏移的取值为0或正整数。
举个例子：当UE尚未收到第一跨时隙调度状态的第一指示信息时，UE设定一个默认跨时隙调度状态，该默认跨时隙调度状态对应的时隙偏移的取值为一个最小值，如0。
本申请实施例中，终端监控的所有的PDCCH DCI format都可以携带所述第一指示信息。
本申请实施例中，上述通过PDCCH指示跨时隙调度状态的方案可以与DRX机制共存，其中，所述终端接收所述网络设备发送的专用控制信道，所述专用控制信道携带第二指示信息，所述第二指示信息用于指示所述默认跨时隙调度状态；所述终端根据所述第二指示信息，在DRX ON状态起始时刻进入所述默认跨时隙调度状态，以及在DRX ON结束时刻进入所述默认跨时隙调度状态。举个例子：1)当UE进入DRX ON状态时，UE按照DRX ON之前的专用控制信道指示的默认跨时隙调度状态进行通信。2)当DRX ON的结束时，UE回到默认跨时隙调度状态进行通信。
参照图5，默认跨时隙调度状态对应的时隙偏移为0，即同时隙调度。之后，UE接 收到PDCCH，PDCCH包括数据信道的调度信息(时域调度信息和频域调度信息)和第一指示信息，图5将这种PDCCH简称为调度+指示1或者调度+指示0，其中，调度是指数据信道的调度信息，指示1对应跨时隙调度状态1，指示0对应跨时隙调度状态0。此外，PDCCH还可以不包含任何的数据信道的调度信息和第一指示信息，图5将这种PDCCH简称为无调度。如图5所示，左侧虚线框内的PDCCH指示UE进入跨时隙调度状态1，UE会在接收到PDCCH的下一个时隙进入跨时隙调度状态1；右侧虚线框内的PDCCH指示UE进入跨时隙调度状态0，UE会在接收到PDCCH后的下x个时隙进入跨时隙状态0，在一个例子中，x＝MAX(a，S C)。如图5所示的例子中，跨时隙调度状态1对应的时隙偏移为1个时隙，跨时隙调度状态0对应的时隙偏移为0个时隙。

场景二：
所述第一通信状态为数据信道的第一MIMO传输层数状态；所述终端将所述第一MIMO传输层数状态与所述终端当前所处的第二MIMO传输层数状态进行比较；若所述第一MIMO传输层数状态与所述第二MIMO传输层数状态不同，则所述终端在第二时隙进入所述第一MIMO传输层数状态。
举个例子：UE在slot n接收网络设备发送的PDCCH。通过PDCCH中的N比特(bit)用于指示数据信道(PDSCH或PUSCH)的第一MIMO传输层数状态，比如PDCCH中的2bit用于指示第一MIMO传输层数状态。UE将PDCCH中指示的第一MIMO传输层数状态和UE当前的第二MIMO传输层数状态进行比较，如果不同，则UE在slot n+x进入PDCCH所指示的第一MIMO传输层数状态。这里，UE当前的第二MIMO传输层数状态是指UE在slot n对应的MIMO传输层数状态。
本申请实施例中，所述第二时隙与所述第一时隙之间具有x个时隙的偏移，x为正整数。
举个例子：x为常数，如x＝1；或者，x是根据当前PDCCH的子载波宽度等信息推算的。
本申请实施例中，所述第一指示信息包括N个比特位，N为正整数，所述N个比特位的不同取值用于表示不同的第一MIMO传输层数状态，所述第一MIMO传输层数状态与所述N个比特位的取值之间的对应关系由高层信令配置。这里，高层信例如是RRC信令。
本申请实施例中，本申请实施例还提供一种容错机制，具体地：所述终端确定第一数据部分的MIMO传输层数大于所述终端当前所处的第二MIMO传输层数状态限制的传输层数的情况下，所述终端向所述网络设备发送负反馈消息，所述第一数据部分是指所述终端在所述第一时隙接收到的所述PDCCH指示的数据部分。
举个例子：当UE在slot n接收到PDCCH指示的数据部分的第二MIMO传输层数超过所示UE当前状态所限制的最大传输层数，UE反馈NACK给网络设备。
这里，所述终端当前所处的第二MIMO传输层数状态限制的传输层数，定义为：
对于PDSCH，所述终端当前所处的第二MIMO传输层数状态限制的传输层数为所述终端预期接收的PDSCH的最大传输层数；或者，
对于PUSCH，所述终端当前所处的第二MIMO传输层数状态限制的传输层数为所述终端能传输的PUSCH的最大传输层数。
本申请实施例中，当PDCCH调度的数据部分的MIMO传输层数与终端当前所处的第二MIMO传输层数状态限制的传输层数不符时，该PDCCH中的其他域，如第一指示信息、功控信息等仍然有效。
本申请实施例的技术方案，可让网络更合理地触发终端侧的节能功能。本申请实施例的技术方案对现有的PDCCH进行扩展，扩展后的PDCCH同时支撑数据信道的调度 功能和终端的节能指示功能，不需要额外的节能物理层信号。本申请实施例采用PDCCH这种动态信令，可以让终端尽快地进入节能状态，节能的自适应时间尺度可以从数十微秒降低至微秒级。此外，本申请实施例的技术方案实现了终端在丢失PDCCH后的容错处理。
需要说明的是，本申请实施例中采用的方法是以跨时隙调度状态和MIMO传输层数状态为例，本申请的重要特征为通过PDCCH来触发不同的通信状态的切换，对于通信状态的切换方式可以扩展到其他的信令过程，也可以扩展终端的其他节能状态，如终端的最大接收天线数的状态，终端的测量周期的状态等等。
