Definitions

  • This application relates to the field of communication technology, and in particular to a communication method and device.
  • the network device will start the discontinuous reception inactivity timer (drx-InactivityTimer) at the first symbol after the symbol where the physical downlink control channel (PDCCH) of the DCI is transmitted.
  • drx-InactivityTimer discontinuous reception inactivity timer
  • the UE only after successfully decoding the DCI will the UE know whether the DCI indicates a new uplink or downlink data transmission. If the DCI indicates a new uplink or downlink data transmission, the UE starts the drx-InactivityTimer. The count value of the timer is still counted from the first symbol after the symbol where the PDCCH is located.
  • the network equipment and the UE will have an impact on the discontinuous reception activation time. Understand inconsistencies.
  • the network device thinks that the drx-InactivityTimer is running, so this time period is the discontinuous reception activation time; on the other hand, because the UE has not successfully decoded the DCI and has not started the drx-InactivityTimer, the UE thinks that the time period is non-inactive. Continuously receive activation time. If the network device sends the DCI to schedule the UE on the PDCCH during this time period, the UE will miss the PDCCH, resulting in a waste of network resources and power consumption, and also an increase in the data delay of the UE.
  • the reason that the UE decoding DCI time exceeds the discontinuous reception activation time may have the following two points:
  • the current downlink scheduling and uplink scheduling are restricted by minimum K0 and minimum K2 respectively.
  • the UE does not know whether the decoded DCI indicates downlink scheduling or uplink scheduling before successfully decoding the DCI, so if the UE wants to successfully decode the DCI before the scheduled data, the UE decoding time is limited by the minimum K0 and minimum K2 The smaller value of.
  • the UE has to reserve time for the uplink data to be sent after successfully decoding the DCI. Therefore, if the minimum K2 is less than the minimum K0, the UE generally does not extend the decoding time to N+minimum At the end of the K2-1 time slot, but to reserve time for data preparation.
  • minimum K2 greater than minimum K0 for downlink scheduling and uplink scheduling, the UE can extend the DCI decoding time to the time slot corresponding to N+minimum K0-1, for example, to the end time of the time slot corresponding to N+minimum K0-1 .
  • minimum K0 represents the minimum time slot interval between PDCCH and physical downlink shared channel (physical downlink shared channel, PDSCH)
  • minimum K2 represents the time between PDCCH and physical uplink shared channel (physical uplink shared channel, PDSCH).
  • N is the slot number of the slot where the DCI is located.
  • minimum K2 will be greater than or equal to minimum K0, and this application is also based on this assumption.
  • the shortest time for the UE to decode DCI may also require 2 to 3 time slots.
  • the network device will start the drx-InactivityTimer at the first symbol after the symbol where the PDCCH is located.
  • the network device considers that the UE is in discontinuous reception activation time during the operation of the drx-InactivityTimer.
  • the UE will consider the time slot as the non-discontinuous reception activation time, so the UE will not monitor the PDCCH. If the network device sends the DCI scheduling UE on the PDCCH in this time slot, the UE will miss the PDCCH, resulting in a waste of network resources and power consumption, and an increase in UE data delay.

Description

一种通信方法及装置
相关申请的交叉引用
本申请要求在2019年08月02日提交中国专利局、申请号为201910713049.4、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在现有技术中，如果用户设备(user equipment，UE)在不连续接收激活时间(DRX active time)的结尾收到下行控制信息(downlink control information，DCI)，且该DCI用于指示新的上行或下行数据传输，则网络设备会在传输该DCI的物理下行控制信道(physical downlink control channel，PDCCH)所在符号之后的第一个符号启动不连续接收非激活定时器(drx-InactivityTimer)。但对于UE而言，UE只有成功译码DCI之后才会得知该DCI是否指示新的上行或下行数据传输，若该DCI指示新的上行或下行数据传输，UE启动drx-InactivityTimer，此时UE对定时器的计数值仍然从PDCCH所在符号之后的第一个符号算起。
但是，由于UE译码DCI的时间可能会超过不连续接收激活时间，则针对超过不连续接收激活时间且UE仍然在译码DCI的时间段，网络设备和UE会产生对不连续接收激活时间的理解不一致的问题。一方面，网络设备认为drx-InactivityTimer在运行，所以该时间段为不连续接收激活时间；另一方面，由于UE还没成功译码DCI，未启动drx-InactivityTimer，则UE认为该时间段是非不连续接收激活时间。如果网络设备在该时间段内在PDCCH发送DCI调度UE，则UE会漏掉该PDCCH，造成网络资源和功耗的浪费，同时也造成UE数据时延的增大。
其中，UE译码DCI的时间超过不连续接收激活时间的原因可能有以下两点：
1)当前的下行调度和上行调度分别有minimum K0和minimum K2的限制。UE在译码DCI成功之前不知道译码的DCI指示的是下行调度还是上行调度，所以如果UE想要在调度的数据之前译码DCI成功，那么UE译码时间受限于minimum K0和minimum K2的较小值。另外，针对DCI调度PUSCH的情况，UE在译码DCI成功之后还要预留准备所发送的上行数据的时间，所以如果minimum K2小于minimum K0，UE一般不会将译码时间延长到N+minimum K2-1时隙的结尾，而是要预留数据准备的时间。而对于minimum K2大于minimum K0，针对下行调度和上行调度，UE可以将DCI译码时间延长到N+minimum K0-1对应时隙，例如可以延长到N+minimum K0-1对应时隙的结束时刻。其中，minimum K0表示PDCCH与物理下行共享信道(physical downlink shared channel，PDSCH)之间的时隙间隔的最小值，minimum K2表示PDCCH与物理上行共享信道(physical uplink shared channel，PDSCH)之间的时隙间隔的最小值。N为DCI所在时隙的时隙编号。
一般情况下，minimum K2会大于或等于minimum K0，本申请中也是基于这个假设。
2)UE能力限制。例如，当子载波间隔(subcarrier spacing，SCS)较大时(比如SCS＝120KHz)，UE译码DCI时间最短可能也需要2～3个时隙。
如图1所示，在持续时间(on duration)的最后一个时隙，网络设备通过PDCCH传输DCI调度UE，该DCI指示新的下行数据传输。由于minimum K0＝2，所以UE译码DCI的时间可能持续到持续时间之后的一个时隙。按照现有协议，网络设备会在PDCCH所在符号之后的第一个符号启动drx-InactivityTimer，按照现有协议规定网络设备认为drx-InactivityTimer运行期间UE是处于不连续接收激活时间。而若UE在持续时间后的一个时隙处于译码DCI状态，UE此时已经离开不连续接收激活时间，UE会认为该时隙是非不连续接收激活时间，所以UE不会监听PDCCH。如果网络设备在该时隙在PDCCH发送DCI调度UE，则UE会漏掉该PDCCH，造成网络资源和功耗的浪费，也造成了UE数据时延的增大。

采用上述方法，通过修改drx-InactivityTimer的启动时间，网络设备和UE都在UE已经译码DCI成功后同时启动或重启drx-InactivityTimer，可以避免网络设备和UE对不连续接收激活时间的理解不一致的问题。
在一种可能的设计中，X＝minimum K0，或者X＝Z，或者X＝max(minimum K0,Z)，minimum K0表示PDCCH与PDSCH之间的时隙间隔的最小值，Z表示第一常数值。

具体实施方式
下面结合附图，对本申请的实施例进行描述。
首先，对本申请实施例涉及的现有技术进行简单介绍：
在NR Rel-15版本中，网络设备在PDCCH发送DCI调度UE接收下行数据或上行数 据时，该DCI可以指示PDSCH(对应下行数据)或PUSCH(对应上行数据)的传输参数。这些传输参数用于确定PDSCH或PUSCH的时域资源位置。具体来说，PDSCH时域资源位置包括：PDSCH所在的时隙，以及PDSCH在上述时隙中所占用的符号的起始位置和长度。PUSCH时域资源位置包括：PUSCH所在的时隙，以及PUSCH在上述时隙中所占用的符号的起始位置和长度。
其中，PDCCH与PDSCH之间的时隙间隔用K0表示；PDCCH与PUSCH之间的时隙间隔用K2表示。网络设备会通过RRC信令，为UE配置K0和K2的可用值集合，例如通过配置时域资源分配(time-domain resource allocation，TDRA)表格，该表格包括多个K0和K2，然后通过DCI从TDRA的表格中的可用值集合中指示一个值，用于当前这次数据调度。如果PDCCH与PDSCH(或PUSCH)在相同时隙，称为同时隙调度(对应K0＝0或K2＝0的情况)，如果PDCCH与PDSCH(或PUSCH)在不同时隙，称为跨时隙调度(对应K0>0或K2>0的情况)。
但是，在UE译码DCI之前，UE不知道DCI指示的K0或K2是多少。以下行调度为例，如果网络设备给UE配置的K0可用值集合中既包括K0＝0，又包括K0>0的情况，UE在译码DCI之前不知道当前这次调度到底是同时隙调度还是跨时隙调度，只有当UE成功译码DCI，获得K0之后才会知道当前调度的PDSCH在哪个时隙。
因此，上述NR Rel-15的调度方式不利于UE节能，具体可以体现在以下两个方面：
一方面，以下行调度为例，如图2左侧所示，如果UE不知道当前时隙内是否是同时隙调度(比如，只要网络设备配置的TDRA表格中包括K0＝0，就可能存在同时隙调度)，为了避免丢失信号，UE在接收DCI之后，译码DCI的同时，需要缓存下行信号，若当前这次数据调度是跨时隙调度，则UE提前缓存的这部分信号是没有必要的，这造成了功耗的浪费。如图2右侧所示，如果UE提前能够知道当前这次数据调度是跨时隙调度，那么UE在接收DCI之后，译码DCI的同时，就可以把射频模块关闭，不缓存任何信号，从而可以达到节能的效果(如图2右侧所示，右下角阴影部分即为节省的能量)。
另一方面，UE译码DCI的速度也会影响UE的功耗。如果UE译码DCI的速度较快，则需要工作在较高的时钟频率与电压，所以功耗较高。但是，如果UE提前知道PDCCH与PDSCH(或PUSCH)之间有一个最小的时隙间隔，则UE就可以降低DCI的译码速度，从而降低工作的时钟频率和电压，以实现节省功耗。例如，如果网络设备指示了UE针对“K0”值的当前可用值的最小值，即网络通过RRC信令配置或者通过L1信令动态指示了minimum K0值，如图3所示，则UE可以降低DCI的译码速度，例如，针对minimum K0大于等于1，可以将译码DCI的时间延长到(n+minimum K0-1)所在时隙的结尾，其中，n是DCI所在的时隙编号。
由上可知，通过设定“K0和K2”的当前可用值的最小值，即minimum K0和minimum K2，UE可以在译码DCI之前，就获知当前这次调度为同时隙调度还是跨时隙调度，若确定当前这次调度为跨时隙调度，则UE可以在译码成功DCI之前不缓存任何信号，进入微睡眠(micro-sleep)(比如关掉接收RF)，以实现节省功耗，同时，UE可以降低DCI的译码速度，从而降低时钟频率和工作电压，以实现节省功耗。
UE在RRC连接态可能会被配置不连续接收(connected-discontinuous reception，C-DRX)，其目的是为了使终端设备每隔一定的周期进入不连续接收持续时间(DRX ON Duration)去收发数据，而在其他时候可以进入睡眠状态，不去监听PDCCH，从而可以实 现节省UE功耗。被配置DRX的UE的状态可以分为不连续接收激活(DRX Active)态和不连续接收非激活(DRX non-active)态，UE处于DRX Active态的时间称为不连续接收激活时间(DRX Active Time)。当UE处于DRX Active Time，UE会持续监听PDCCH。如果UE离开DRX Active态，即进入睡眠状态(DRX non-active)，则UE不去监听PDCCH。当以下任意一个定时器在运行时，UE即处于DRX Active Time，这些定时器包括：不连续接收持续时间定时器(drx-onDurationTimer)，不连续接收非激活定时器(drx-InactivityTimer)，不连续接收下行重传定时器(drx-RetransmissionTimerDL)，不连续接收上行重传定时器(drx-RetransmissionTimerUL)，随机接入竞争解决定时器(ra-ContentionResolutionTimer)。此外，DRX active time还包括其他情况，例如：UE在PUCCH上发送了调度请求(scheduling request，SR)之后的等待期间；UE在成功接收到基于非竞争(non-contention based)随机接入的随机接入响应(random access response，RAR)之后还未收到指示新的上行或下行数据传输的PDCCH期间。
应理解的是，当UE处于DRX Active Time，UE会持续监听PDCCH。如果离开了DRX Active time，则UE不去监听PDCCH。具体的，这里的PDCCH的循环冗余校验(cyclic redundancy check，CRC)可以是如下的一种无线网络临时标识(radio network temporary identifier,RNTI)加扰的：小区无线网络临时标识(cell RNTI,C-RNTI),配置的调度无线网络临时标识(Configured Scheduling RNTI，CS-RNTI),中断无线网络临时标识(Interruption RNTI，INT-RNTI),时隙格式指示无线网络临时标识(Slot Format Indication RNTI，SFI-RNTI),半持续信道状态信息无线网络临时标识(Semi-Persistent CSI RNTI，SP-CSI-RNTI),PUCCH传输功率控制无线网络临时标识(transmit power control-PUCCH-RNTI，TPC-PUCCH-RNTI)，PUSCH传输功率控制无线网络临时标识(transmit power control-PUSCH-RNTI，TPC-PUSCH-RNTI),和SRS传输功率控制无线网络临时标识(transmit power control-SRS-RNTI，TPC-SRS-RNTI)。
图4表示配置了DRX周期之后的UE状态示例。在C-DRX周期的开始时刻会首先进入DRX ON Duration，同时开启drx-onDurationTimer，如果在DRX ON Duration期间UE收到用于指示新的下行或上行数据传输的PDCCH，则会开启drx-InactivityTimer。UE将一直处于DRX-Active态直到drx-InactivityTimer超时，或者UE收到相关的控制单元(MAC CE)信令使该drx-InactivityTimer提前停止。在现有技术中，定时器drx-InactivityTimer是在指示新的上行或下行数据传输的PDCCH所在符号之后第一个符号启动或重启，如图5所示，图5中PDCCH调度新的PDSCH传输。
本申请主要应用于第5代无线通信***(new radio，NR)***，还可以应用于其它的通信***，例如，窄带物联网(narrow band-internet of things，NB-IoT)***，机器类通信(machine type communication，MTC)***，未来下一代通信***等。
本申请实施例中涉及的网元包括终端设备和网络设备。如图6所示，网络设备和终端设备组成一个通信***，在该通信***中，网络设备通过下行信道发送信息给终端设备，终端设备通过上行信道发送信息给网络设备。其中，终端设备可以为手机、平板电脑、带无线收发功能的电脑、物联网终端设备等，也可以称为移动站(mobile station)、移动台(mobile)、远程站(remote station)、远程终端(remote terminal)、接入终端(access terminal)、用户代理(user agent)，还可以为车与车(vehicle-to-vehicle，V2V)通信中的汽车、机器 类通信中的机器等，在此不作限定。网络设备可以为各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点、演进型基站(eNodeB)、无线保真接入点(wireless fidelity access point，WiFi AP)、全球微波接入互操作性(worldwide interoperability for microwave access base station，WiMAX BS)等，在此不作限定。此外，在采用不同的无线接入技术的***中，具备提供无线接入功能的网络设备的名称可能会有所不同，例如，在LTE***中，称为演进的节点B(evolved NodeB，eNB或者eNodeB)，在第三代(3rd generation，3G)***中，称为节点B(Node B)，在NR***中，称为gNB。

本申请实施例中，第一通信设备可以是终端设备也可以是终端设备中的芯片***。
基于此，如图7所示，本申请实施例提供一种通信方法，该方法包括：
S701：第一通信设备在第一不连续接收激活时间内从网络设备接收到第一DCI，第一DCI用于指示新的上行或下行数据传输。
相应的，网络设备在第一不连续接收激活时间内向第一通信设备发送第一DCI。网络设备在向第一通信设备发送的第一DCI所占用的符号之后的第一个符号启动不连续接收非激活定时器。
S702：第一通信设备在第一不连续接收激活时间之后的第一时间段内不期待从网络设备接收PDCCH，第一时间段的起始时刻为第一不连续接收激活时间的结束时刻，第一时间段的结束时刻位于第二不连续接收激活时间之内。
相应的，网络设备在第一不连续接收激活时间之后的第一时间段内不向第一通信设备发送PDCCH。
S703：第一通信设备在第一时间段之后监听PDCCH。
相应的，网络设备在第一时间段之后可以向第一通信设备发送PDCCH。
应理解的是，网络设备发送PDCCH是指网络设备在PDCCH上发送DCI，例如第一DCI或其他类型的DCI。第一通信设备接收PDCCH是指盲检测PDCCH，或者说是监听PDCCH，或者说是在PDCCH接收下行控制信息，或者说是在PDCCH盲检测下行控制信息。第一通信设备不期待从网络设备接收PDCCH，表示第一通信设备不期待PDCCH上存在DCI，或者说是假设网络设备不在PDCCH发送DCI。
应理解的是，第一通信设备在第一不连续接收激活时间之后的第一时间段内不期待从网络设备接收PDCCH，所述PDCCH是网络设备只在DRX active time内所发送的PDCCH，例如，第一通信设备不期待收到其CRC由如下RNTI所加扰的DCI：C-RNTI,CS-RNTI,INT-RNTI,SFI-RNTI,SP-CSI-RNTI,TPC-PUCCH-RNTI,TPCPUSCH-RNTI,and TPC-SRS-RNTI。
在本申请实施例中，第一DCI所占用的符号(或用于指示新的上行或下行数据传输的PDCCH所在的符号)位于第一不连续接收激活时间内。第一不连续接收激活时间可以是 指以下任意一个定时器在运行时，这些定时器包括：drx-onDurationTimer，drx-InactivityTimer，drx-RetransmissionTimerDL，drx-RetransmissionTimerUL，ra-ContentionResolutionTimer。此外，第一不连续接收激活时间还包括其他情况，例如：第一通信设备在PUCCH上发送了SR之后的等待期间；第一通信设备在成功接收到基于非竞争随机接入的RAR之后还未收到指示新的上行或下数据传输的PDCCH期间。第一DCI所占用的符号(或用于指示新的上行或下行数据传输的PDCCH所在的符号)之后的第一个符号为第二不连续接收激活时间的开始时刻。第二不连续接收激活时间是指drx-InactivityTimer运行的时间段。
应理解的是，从第一DCI所占用的符号(或用于指示新的上行或下行数据传输的PDCCH所在的符号)之后的第一个符号开始，第二不连续接收激活时间对应的定时器drx-InactivityTimer计时开始(即启动或重启)，此时，第一不连续接收激活时间对应的定时器尚未计时结束，但不连续接收激活时间得到更新，所以这里将drx-InactivityTimer启动或重启的时刻定义为第二不连续接收激活时间的开始时刻。注意，第一不连续接收激活时间的结束时刻仍然是第一不连续接收激活时间对应的定时器自然计时结束的时刻。例如，若第一不连续接收激活时间对应的定时器为drx-onDurationTimer，则第一不连续接收激活时间的结束时刻是drx-onDurationTimer计时结束(即：超时)的时刻。若网络设备在drx-onDurationTimer计时期间(即On Duration)发送了第一DCI，则网络设备在第一DCI之后的第一个符号启动drx-InactivityTimer，不连续接收激活时间得到更新，第二不连续接收激活时间开始。而第一不连续接收激活时间的结束时刻位于第二不连续接收激活时间开始时刻之后。再例如，若第一不连续接收激活时间对应的定时器为drx-InactivityTimer，当前drx-InactivityTimer正在运行，若网络设备在drx-InactivityTimer计时期间发送了第一DCI，则网络设备在第一DCI之后的第一个符号重启drx-InactivityTimer，不连续接收激活时间得到更新，第二不连续接收激活时间开始。而第一不连续接收激活时间的结束时刻是drx-InactivityTimer重启之前自然计时超时的时刻，位于第二不连续接收激活时间开始时刻之后。
在一种可能的设计中，第一通信设备在第一不连续接收激活时间内的第二时间段从网络设备接收到至少一个第一DCI，且第一通信设备在第一不连续接收激活时间内的倒数第X个时隙未从网络设备接收到第一DCI。第二时间段的起始时刻为第一不连续接收激活时间内的倒数第X-1个时隙的起始时刻，第二时间段的结束时刻为第一不连续接收激活时间的结束时刻。进一步地，若第一通信设备在第二时间段内接收到的第一个第一DCI所在时隙为第一不连续接收激活时间内的倒数第y个时隙，y＜X，y为正整数，则第一时间段的长度为X-y个时隙。
应理解的是，若第一通信设备在第一不连续接收激活时间内的倒数第X个时隙从网络设备接收到第一DCI，y＝X，此时第一通信设备可以在第一不连续接收激活时间内对第一DCI译码成功，即第一DCI译码时间不会超过第一不连续接收持续时间，第一时间段为0，且不会出现网络设备和第一通信设备对不连续接收激活时间理解不一致的问题。若第一通信设备在第一不连续接收激活时间内的倒数第X个时隙之前的时隙(例如倒数第X+1个时隙)从网络设备接收到第一DCI，y＞X，此时第一通信设备可以在第一不连续接收激活时间内对第一DCI译码成功，即第一DCI译码时间不会超过第一不连续接收持续时间，不存在第一时间段，且不会出现网络设备和第一通信设备对不连续接收激活时间理解不一致 的问题。
以下对X的三种可能取值方式进行详细说明。其中，X＝minimum K0，或者X＝Z，或者X＝max(minimum K0,Z)，minimum K0表示PDCCH与PDSCH之间的时隙间隔的最小值，Z表示第一常数值。
方式1：X＝minimum K0
minimum K0是当前生效的最小K0值，表示PDCCH调度的PDSCH与该PDCCH之间的时隙间隔大于或等于minimum K0。
示例性地，若PDCCH传输的第一DCI所在时隙为n，则第一DCI调度的PDSCH在n+minimum K0时隙或者在n+minimum K0之后的时隙，UE不期待在n+minimum K0时隙之前收到第一DCI调度的PDSCH。因此，UE可以将第一DCI译码时间持续到n+minimum K0-1对应时隙，如果UE译码第一DCI时间超过UE第一不连续接收激活时间，则UE在超过第一不连续接收激活时间但仍然在译码第一DCI的时间段不监听PDCCH，当UE译码第一DCI成功，通过解析第一DCI得知该第一DCI指示新的下行数据传输，则UE启动或重启drx-InactivityTimer，当启动了drx-InactivityTimer之后UE就重新回到不连续接收激活时间，此时UE进入第二不连续接收激活时间，UE恢复监听PDCCH。值得注意的是，虽然网络设备在承载第一DCI的PDCCH所在符号之后的第一个符号启动了drx-InactivityTimer，但由于UE译码DCI需要一定的时间，UE在启动drx-InactivityTimer时的计时值要从承载第一DCI的PDCCH所在符号之后的第一个符号算起，而第二不连续接收激活时间按照网络设备启动drx-InactivityTimer的时刻开始算起，也就是从承载第一DCI的PDCCH所在符号之后的第一个符号开始定义为第二不连续接收激活时间的起始时刻。例如，考虑定时器为倒计时，drx-InactivityTimer的初始值为T，UE译码第一DCI的用时为delta，则UE在完成第一DCI译码启动drx-InactivityTimer时的计时值为T-delta，目的是为了使UE和网络设备的定时器计时值对齐。应理解的是，UE可以获知自身译码第一DCI的用时delta。
在一示例中，如图8所示，若X＝minimum K0＝2，DRX on duration(即第一不连续接收激活时间)时长为2个时隙，网络设备在DRX on duration的最后一个时隙通过PDCCH调度了新的下行数据传输，y＝1，则网络设备在PDCCH所在符号之后的第一个符号启动drx-InactivityTimer，网络设备更新DRX active time，即drx-InactivityTimer的运行时段为第二不连续接收激活时间。其中，第一时间段的长度为X-y＝1个时隙，第一时间段的起始位置为DRX on duration的结束位置。网络设备在第一时间段不发送PDCCH，在第一时间段之后可以发送PDCCH。
UE在第一时间段内不监听PDCCH。由于minimum K0＝2，所以UE确定PDCCH调度的PDSCH不会出现在n+minimum K0时隙之前的时隙，所以UE可以将DCI译码速度降低，从而可以将DCI译码时间延长到n+minimum K0-1时隙(图8中on duration之后的第一个时隙)，这里，UE将DCI译码时间延长到了n+minimum K0-1时隙的结尾，也就是第一时间段的结束位置。当UE译码DCI成功之后会启动drx-InactivityTimer，UE恢复监听PDCCH。
在又一示例中，如图9所示，若X＝minimum K0＝3，当第一个drx-InactivityTimer(即第一不连续接收激活时间)正在运行时(为了描述方便，这里将drx-InactivityTimer重启之前称为第一个drx-InactivityTimer)，网络设备在第一个drx-InactivityTimer的倒数第2个时 隙通过PDCCH调度了新的下行数据PDSCH，y＝2，则网络设备在PDCCH所在符号之后的第一个符号重启drx-InactivityTimer，网络设备更新DRX active time，即drx-InactivityTimer重启之后的运行时段为第二不连续接收激活时间。第一时间段的长度为X-y＝1个时隙，第一时间段的起始位置为drx-InactivityTimer重启之前自然计时的结束位置，即第一个drx-InactivityTimer自然计时结束的位置。UE在第一时间段内不监听PDCCH。由于minimum K0＝3，UE可以将DCI译码时间延长到n+minimum K0-1时隙，即时隙n+2，比如延长到时隙n+2的结束位置，也就是第一时间段的结束位置。当UE译码DCI成功之后会重启drx-InactivityTimer，UE恢复监听PDCCH。
与图9类似，如图10所示，若X＝minimum K0＝3，当第一个drx-InactivityTimer(即第一不连续接收激活时间)正在运行时，网络设备在第一个drx-InactivityTimer的倒数第一个时隙通过PDCCH调度了新的下行数据传输，则y＝1，第一时间段的长度为X-y＝3-1＝2个时隙。UE在第一时间段内不监听PDCCH。
应理解的是，针对上述图8到图10，UE译码DCI的时间都持续到了n+minimum K0-1时隙的结束位置，UE认为第一时间段不是处于不连续接收激活时间，因为在第一时间段内UE还未启动或重启drx-InactivityTimer。但是，UE译码DCI的时间取决于UE实现，所以UE的DCI译码时间可能不会持续到n+minimum K0-1时隙的结尾，而是在n+minimum K0-1时隙的结尾之前的任何位置都有可能译码DCI成功。因此，本申请实施例并不限制UE的DCI译码时间，也不会限制UE在n+minimum K0-1时隙的结尾启动或重启drx-InactivityTimer，只要UE译码DCI成功，UE即可获知该DCI是否指示新的上行或下行数据传输，若是，则UE启动或重启drx-InactivityTimer。否则，UE进入DRX non-active态。此外，不管UE在哪个时刻启动或重启drx-InactivityTimer，该定时器的计时值都要从用于指示新的上行或下行数据传输的PDCCH所在符号之后的第一个符号算起。
需要说明的是，由于网络设备并不知道UE何时译码DCI成功，所以，即使UE译码速度较快，在第一时间段结束之前就译码DCI成功了，网络设备也不知道UE已经译码DCI成功。为了避免网络设备和UE对第一时间段是否处于不连续接收激活时间的理解不一致的问题。因此，不管UE何时译码DCI成功，UE在第一时间段内都不期待收到PDCCH，相应地，网络设备在第一时间段不发送PDCCH。
例如，如图11，若X＝minimum K0＝2，但是UE译码DCI时间并没有持续到n+1时隙，而是在PDCCH所在时隙的结尾译码DCI成功，则UE启动drx-InactivityTimer，此后UE处于DRX active time，第一时间段也位于DRX active time内，但UE在第一时间段内不监听PDCCH。网络设备在第一时间段内不发送PDCCH。在第一时间段之后，UE恢复正常监听PDCCH，网络设备也可以发送PDCCH。
下面结合具体示例对图7所示实施例进行详细说明，应理解的是，以下各个示例仅为举例，不作为本申请的限定。
示例1，如图12所示，PDCCH-1，PDCCH-2，PDCCH-3都用于指示新的数据传输。网络设备在On Duration内发送PDCCH-1所在符号之后的第一个符号启动drx-InactivityTimer，第一不连续接收激活时间为从PDCCH-1所在符号之后的第一个符号开始drx-InactivityTimer运行的时间段。若X＝3，PDCCH-2所在的时隙为drx-InactivityTimer运行时段内第一个指示新的数据传输的PDCCH，PDCCH-2所在的时隙为drx-InactivityTimer运行时段内的倒数第2个时隙，即y＝2。因此，第一时间段为 drx-InactivityTimer运行时段之后的1个时隙。
示例2，如图13所示，若X＝minimum K0＝3，PDCCH-1和PDCCH-2都调度了新的下行数据传输。PDCCH-1是在第一个drx-InactivityTimer的运行时段的倒数第2个时隙发送的，第二个drx-InactivityTimer在PDCCH-1所在符号之后的第一个符号重启。因此，网络设备在发送PDCCH-2时，已经不再是第一个drx-InactivityTimer的运行时段的倒数第一个时隙了，而是第二个drx-InactivityTimer的运行时段的倒数第4个时隙。由于PDCCH-1所在时隙为第一个drx-InactivityTimer的运行时段的倒数第2个时隙，y＝2，则第一时间段时长为X-y＝1个时隙，第一时间段的起始位置为第一个drx-InactivityTimer自然计时超时的时刻，也可以说是n+y-1时隙的结束位置，即n+1时隙的结束位置，n为PDCCH-1所在的时隙。网络设备在第一时间段不发送PDCCH。由于PDCCH-2是在第二个drx-InactivityTimer的运行时段的倒数第4个时隙发送，y＝4，不满足y<X，所以不存在第一时间段，第三个drx-InactivityTimer在PDCCH-2所在符号之后的第一个符号重启。因此，图13中，只有第一时间段网络设备不发送PDCCH，在其他时间段，网络设备都可以发送PDCCH调度UE。
方式2：X＝Z
第一常数值可以是标准中预先规定好的。应理解的是，第一常数值Z与子载波间隔(subcarrier spacing，SCS)关联，第一子载波间隔对应的第一常数值大于或等于第二子载波间隔对应的第一常数值，其中，第一子载波间隔大于第二子载波间隔。比如，当SCS＝15KHz/30KHz时，所有UE都能在一个时隙内译码DCI成功，当SCS＝60KHz/120KHz时，UE译码DCI的时间可能需要大于1个时隙，比如所有UE都能够在n+2时隙之前译码成功(此时UE译码DCI的时间可能持续到n+1时隙的结尾，时隙n为用于指示新的上行或下行数据传输的PDCCH所在时隙的时隙编号)。Z的取值与子载波间隔的关系可以参阅表1或者表2。
表1
SCS Z(单位：slots)
15KHz 1
30KHz 1
60KHz 2
120KHz 2
表2
SCS Z(单位：slots)
15KHz 1
30KHz 1
60KHz 1
120KHz 2
以表2为例，当SCS＝15KHz/30KHz/60KHz时，Z＝1，当SCS＝120KHz时，Z＝2，因此，只有当SCS＝120KHz时，才存在第一时间段，因为，当Z＝2时，第一时间段的长度X-y才可能大于等于1个时隙。
此外，应理解的是，第一常数值Z可以涵盖所有第一通信设备的译码时间，即第一常数值Z反映了对所有第一通信设备的译码时间的最低要求。示例性地，用n表示PDCCH所在的时隙的编号，UE在n+Z-1时隙的结束位置已经译码DCI成功，但是UE完成DCI 译码的时刻可能在n+Z-1时隙的结束位置之前。
在方式1中，UE译码DCI的时间可以随着minimum K0的增大而延长。在方式2中，UE译码DCI的时间并不能随着minimum K0的增大而延长，而是受到一个常数的限制。该常数反应了UE能力，该常数表示的时间包括了UE译码DCI的时间。
需要说明的是，这里所说的预先定义的常数可以由其他符号表示，比如M、或N、或Q等，只要该常数能够反映DCI译码的时间即可。常数Z可以是预先定义的，也可以是网络设备配置给终端设备的(例如通过无线电资源控制(radio resource control，RRC)信令)，或者是终端设备通过RRC信令上报给网络设备的，承载在UE上报的能力信息(UE capability information)中或者辅助信息(UE assistance information)中。
方式3：X＝max(minimum K0,Z)
方式3是方式1和方式2的结合。
在方式3中，UE可以在minimum K0>Z时延长DCI译码时间，比如延到n+minimum K0-1时隙。但是当minimum K0≤Z时，受限于UE能力，UE并不能因为minimum K0变小而加快译码DCI速度，所以DCI译码时间可能仍然持续到n+Z-1时隙。所以X是取两者的较大值。
与基于上述X的三种可能取值方式相同的构思，在另一种可能的设计中，第一时间段的长度为M个时隙；其中，M＝minimum K0-1，或者M＝Z-1，或者M＝max(minimum K0,Z)-1，minimum K0表示PDCCH与PDSCH之间的时隙间隔的最小值，Z表示第一常数值，Z为正整数。
综上，通过规定UE行为，规定UE在当前不连续接收激活时间之后的第一时间段内不期待收到PDCCH，网络设备在第一时间段内不发送PDCCH，可以避免由于DCI译码时间超过当前不连续接收激活时间造成网络设备和UE对第一时间段是否处于不连续接收激活时间理解不一致的问题，且可以实现节约网络资源，避免功耗浪费。
可以理解的是，如上所描述的方法适用于PDCCH位于一个时隙的最开始的几个符号的情况，例如位于一个时隙的前S个符号，S＝1，或S＝2，或S＝3。该方法也适用于PDCCH位于一个时隙的中间的符号位置或结尾的符号位置的情况。当一个PDCCH位于一个时隙的中间符号或结尾符号时，即PDCCH的盲检搜索空间出现在一个时隙的中间符号或结尾符号时，可以基于UE实现调整DCI的译码速度，使DCI译码仍然在n+X时隙之前完成。
但是，有些情况下，并不能保证在n+X时隙之前完成DCI译码。例如，指示新的上行或下行数据传输的第一DCI位于第一不连续接收时间的倒数第一个时隙的结尾的3个符号，而X＝minimum K0＝1，则第一DCI所在符号的结束符号与第一DCI所在时隙n的下一个时隙的起始符号之间没有时间间隔，自然UE无法在时隙n+1的起始时刻完成DCI译码。此时，UE译码第一DCI的时间也超过了第一不连续接收激活时间，根据如上描述的其中一个方法，例如，确定第一时间段时长为X-y个时隙，其中y＝1，所以第一时间段时长为0，并不能解决由于DCI译码时间超过当前不连续接收激活时间造成网络设备和UE对第一时间段是否处于不连续接收激活时间理解不一致的问题。
为了避免此问题，可以约定，如果DCI位于一个时隙的结尾的S个符号位置，或者如果DCI不是位于一个时隙开始的S个符号位置(S＝1或2或3)，则规定第一时间段的时长为X+1-y个时隙，其中，X和y如之前描述，此处不再赘述。或者，规定第一时间段的时长为X个时隙，X如之前描述，此处不再赘述。
如图14所示，本申请实施例提供一种通信方法，该方法包括：
S1401：第一通信设备在第一不连续接收激活时间内从网络设备接收到第一DCI，第一DCI用于指示新的上行或下行数据传输。
相应的，网络设备在第一不连续接收激活时间内向第一通信设备发送第一DCI。
S1402：第一通信设备在第一DCI所在时隙的时隙编号与X之和所对应的时隙的起始时刻启动或重启不连续接收非激活定时器，X为大于等于0的整数。
相应的，网络设备在第一DCI所在时隙的时隙编号与X之和所对应的时隙的起始时刻启动或重启不连续接收非激活定时器。
其中，第一DCI所在时隙的时隙编号与X之和所对应的时隙的起始时刻为第一DCI所在时隙的时隙编号与X之和所对应的时隙的开始符号。
其中，X＝minimum K0，或者X＝Z，或者X＝max(minimum K0,Z)，minimum K0表示PDCCH与PDSCH之间的时隙间隔的最小值，Z表示第一常数值。
此外，第一通信设备和网络设在第一DCI所在时隙的时隙编号与X之和所对应的时隙的起始时刻启动或重启不连续接收非激活定时器，还可等价描述为：第一通信设备和网络设在第一DCI所在时隙的时隙编号与X-1之和所对应的时隙的结束时刻(或结束符号)启动或重启不连续接收非激活定时器。
示例性地，图15中，X＝minimum K0＝0，图16中，X＝minimum K0＝1，图17中，X＝minimum K0＝2，图中虽然画出了DCI的译码时间，但是本申请实施例并不限制DCI的译码时间。
在图15中，UE在译码DCI成功之后启动drx-InactivityTimer，该定时器的初始值要从PDCCH所在时隙的开始符号算起，也就是UE在启动drx-InactivityTimer时的计时值要扣除从PDCCH所在时隙的起始位置到DCI译码成功之间的时间长度。
图16中，网络设备和UE都在n+1时隙的起始时刻启动drx-InactivityTimer，所以on duration之后的时隙n+1是不连续接收激活时间，不会造成网络设备和UE对该时间段是否处于不连续接收激活时间理解不一致。
图17中，网络设备和UE都在n+1时隙的结束时刻启动drx-InactivityTimer，所以on duration之后的时隙n+1不是不连续接收激活时间，不会造成网络设备和UE对该时间段是否处于不连续接收激活时间理解不一致。
应理解的是，针对X的三种可能取值的说明可以参考上述如图7所示的实施例，重复之处不再赘述。
另外，X的取值也可以是X＝max(minimum K0,1)，这样，当minimum K0＝0时，网络设备和UE启动drx-InactivityTimer的时刻可以不是第一DCI所在时隙的起始时刻，而是第一DCI所在时隙的下一个时隙的起始时刻。这样就不会出现图15中当minimum K0＝0时，drx-InactivityTimer的启动时刻是发生在PDCCH之前的情况。
采用上述实施例，通过修改drx-InactivityTimer的启动时间，网络设备和UE都在UE已经译码DCI成功后同时启动或重启drx-InactivityTimer，可以避免网络设备和UE对不连续接收激活时间的理解不一致的问题。
应理解的是，上述时隙的符号可以为正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。当一个符号的时间长度可以忽略时，一个符号可以称为是一 个时间段的时刻，例如是起始时刻或结束时刻；当一个符号的时间长度不可忽略时，当描述一个时刻为一个符号时，描述的是这个符号的起始时刻或结束时刻。例如，一个时隙的起始时刻为该时隙的开始符号的起始时刻。
可以理解的是，如上所描述的方法适用于PDCCH位于一个时隙的最开始的几个符号的情况，例如位于一个时隙的前S个符号，S＝1，或S＝2，或S＝3。该方法也适用于PDCCH位于一个时隙的中间的符号位置或结尾的符号位置的情况。当一个PDCCH位于一个时隙的中间符号或结尾符号时，即PDCCH的盲检搜索空间出现在一个时隙的中间符号或结尾符号时，可以基于UE实现调整DCI的译码速度，使DCI译码仍然在n+X时隙之前完成。
但是，有些情况下，并不能保证在n+X时隙之前完成DCI译码。例如，指示新的上行或下行数据传输的第一DCI位于第一不连续接收时间的倒数第一个时隙的结尾的3个符号，而X＝minimum K0＝1，则第一DCI所在符号的结束符号与第一DCI所在时隙n的下一个时隙的起始符号之间没有时间间隔，自然UE无法在时隙n+1的起始时刻完成DCI译码。此时，UE译码第一DCI的时间也超过了第一不连续接收激活时间，根据如上描述的其中一个方法，例如，确定drx-InactivityTimer在n+minimum K0时隙的起始时刻启动或重启，并不能解决由于DCI译码时间超过当前不连续接收激活时间造成网络设备和UE对不连续接收激活时间的理解不一致的问题。
为了避免此问题，可以约定，如果DCI位于一个时隙的结尾的S个符号位置，或者如果DCI不是位于一个时隙开始的S个符号位置(S＝1或2或3)，则规定drx-InactivityTimer在n+X+1时隙的起始时刻启动或重启，其中，X如之前描述，此处不再赘述。
如图18所示，本申请实施例提供一种通信方法，该方法包括：
S1801：第一通信设备在第一不连续接收激活时间内从网络设备接收第一DCI，第一DCI用于指示新的上行或下行数据传输。
相应的，网络设备在第一不连续接收激活时间内向第一通信设备发送第一DCI。
S1802：第一通信设备在第一DCI所在符号之后的第Z1+1个符号的起始时刻启动或重启不连续接收非激活定时器，Z1为第二常数值，Z1为大于等于1的整数。
相应的，网络设备在第一DCI所在符号之后的第Z1+1个符号的起始时刻启动或重启不连续接收非激活定时器。
其中，第二常数值Z1与子载波间隔关联，第一子载波间隔对应的第二常数值大于或等于第二子载波间隔对应的第二常数值，其中，第一子载波间隔大于第二子载波间隔。
具体地，可以预先定义一个第二常数值Z1，该第二常数值Z1代表符号个数，表示UE译码DCI的时间长度。
第二常数值Z1可以是标准预先定义好的，也可以是网络设备配置给第一通信设备的(例如通过RRC信令)，或者是第一通信设备通过RRC信令上报给网络设备的，例如，承载在UE上报的能力信息(UE capability information)中或者辅助信息(UE assistance information)中。示例性地，第二常熟值Z1的取值如表3或表4所示。

采用上述实施例，通过修改drx-InactivityTimer的启动时间，网络设备和UE都在UE已经译码DCI成功后同时启动或重启drx-InactivityTimer，可以避免网络设备和UE对不连续接收激活时间的理解不一致的问题。
如图19所示，本申请实施例提供一种通信方法，该方法包括：
S1901：第一通信设备在第一不连续接收激活时间之后的第三时间段内监听PDCCH；第三时间段的起始时刻为第一不连续接收激活时间的结束时刻。
S1902：若第一通信设备在第三时间段结束时处于第二不连续接收激活时间，第一通信设备在第三时间段之后继续监听PDCCH；若第一通信设备在第三时间段结束时未处于第二不连续接收激活时间，第一通信设备在第三时间段之后不监听PDCCH。
在一种可能的设计中，第三时间段的长度为X-y个时隙；其中，第一通信设备在第一不连续接收激活时间内的第二时间段从网络设备接收到至少一个第一DCI，其中，第一DCI通过PDCCH承载，用于指示新的上行或下行数据传输，且第一通信设备在第一不连续接收激活时间内的倒数第X个时隙未从网络设备接收到第一DCI；X为整数，X＝minimum K0，或者X＝Z，或者X＝max(minimum K0,Z)，minimum K0表示PDCCH与PDSCH之间的时隙间隔的最小值，Z表示第一常数值，Z为正整数；第二时间段的起始时刻为第一不连续接收激活时间内的倒数第X-1个时隙的起始时刻，第二时间段的结束时刻为第一不连续接收激活时间的结束时刻；第一通信设备在第二时间段内接收到的第一个第一DCI所在时隙为第一不连续接收激活时间内的倒数第y个时隙，y＜X，y为正整数；
在另一种可能的设计中，第三时间段的长度为M个时隙，M＝minimum K0-1，或者 M＝Z-1，或者M＝max(minimum K0,Z)-1，其中，minimum K0表示PDCCH与PDSCH之间的时隙间隔的最小值，Z为第一常数值。
其中，第一常数值Z与子载波间隔关联，第一子载波间隔对应的第一常数值大于或等于第二子载波间隔对应的第一常数值，其中，第一子载波间隔大于第二子载波间隔。
如图20所示，若minimum K0＝2，第三时间段的长度为M＝minimum K0-1＝1个时隙，第三时间段的起始时刻是on duration的结束位置，第一不连续接收激活时间为on duration的时间段，在on duration内，网络设备没有通过PDCCH调度新的上行或下行数据传输，UE在on duration之后的第三时间段仍然监听PDCCH。UE在第三时间段之后不监听PDCCH。
如图21所示，若minimum K0＝2，第三时间段的长度为M＝minimum K0-1＝1个时隙，第三时间段的起始时刻是on duration的结束位置，第一不连续接收激活时间为on duration的时间段，网络设备在on duration的倒数第一个时隙通过PDCCH调度了新的下行数据传输，但是UE译码DCI的时间持续到了on duration之后的第一个时隙的结尾(即n+1时隙结尾)，UE在第三时间段仍然监听PDCCH。这样，网络设备在第三时间段内也可以发送PDCCH，可以减少数据时延。在第三时间段结尾时，UE由于启动了drx-InactivityTimer重新进入不连续接收激活时间，即第二不连续接收激活时间，所以UE在第三时间段之后继续监听PDCCH。
应理解的是，本申请实施例不限制UE的DCI译码时间，也不限制UE何时启动或重启drx-InactivityTimer。比如，图21中，UE也可能在n+minimum K0-1时隙结尾之前即完成了DCI译码，比如在第三时间段中间完成了DCI译码。
此外，网络设备在第三时间段向第一通信设备发送第二DCI包括但不限于以下几种可能的场景：
第一种可能的场景：网络设备在第三时间段向第一通信设备发送第二DCI，第二DCI通过PDCCH承载，第二DCI不用于指示新的上行或下行数据传输。
其中，第二DCI用于指示重传上行或下行数据，或者第二DCI的DCI格式是非调度类型的DCI格式。例如DCI格式(DCI format)为DCI format 2_0/2_1/2_2/2_3等，或传输功率节省信号的DCI格式，该功率节省信号包括指示UE工作的最大多输入多输出(multiple-input multiple-output，MIMO)层数(包括上行和下行)，或用于指示切换minimum K0和/或K2的值，或专门用于指示部分带宽(Bandwidth part，BWP)切换等。
第二种可能的场景：若网络设备在第一不连续接收激活时间内的第二时间段向第一通信设备发送第一DCI，其中，第一DCI通过PDCCH承载，用于指示新的上行或下行数据传输；网络设备在第三时间段向第一通信设备发送第一DCI。
其中，第二时间段的起始时刻为第一不连续接收激活时间内的倒数第X-1个时隙的起始时刻，第二时间段的结束时刻为第一不连续接收激活时间的结束时刻；X＝minimum K0，或者X＝Z，或者X＝max(minimum K0,Z)，minimum K0表示PDCCH与PDSCH之间的时隙间隔的最小值，Z表示第一常数值。
此外，如果网络在第一不连续接收激活时间的最后的M+1个时隙没有发送用于指示新的上行或下行数据传输的PDCCH，则网络设备在第一不连续接收激活时间之后的第三时间段也不会发送用于指示新的上行或下行数据传输的PDCCH。
如图20所示，minimum K0＝2，M＝minimum K0-1＝1。如果网络设备在on duration内 的最后2个时隙没有通过PDCCH调度新的上行或下行数据传输，则网络设备也不会在on duration之后的第三时间段调度新的上行或下行数据传输，即使UE在第三时间段仍然在监听PDCCH。
如图22所示，minimum K0＝3，M＝minimum K0-1＝2。如果网络设备在on duration内的最后2个时隙没有通过PDCCH调度新的数据传输，但是在on duration之后的第三时间段调度了新的上行或下行数据传输，则网络设备在第三时间段之后的下一个时隙仍然不能继续发送PDCCH，因为UE可能需要到第三时间段之后的下一个时隙的结尾才对PDCCH-1传输的DCI译码成功，从而得知网络设备调度了新的上行或下行数据传输。所以，这又造成了网络设备和UE对第三时间段之后的下一个时隙是否处于不连续接收激活时间的理解不一致的问题。
因此，如果网络设备在第一不连续接收激活时间最后的M+1个时隙没有发送用于指示新的上行或下行数据传输的PDCCH，而是网络设备在第三时间段发送了用于指示新的上行或下行数据传输的PDCCH，则网络设备在第四时间段不发送PDCCH，第四时间段的起始时刻是第三时间段的结束位置。在第四时间段之后，网络设备可以继续发送PDCCH。
第四时间段的时长为：X-y个时隙。其中，X＝M+1。如果M＝minimum K0-1，X＝minimum K0；如果M＝Z-1，X＝Z；如果M＝max(minimum K0,Z)-1，X＝max(minimum K0,Z)。其中，y表示第三时间段内的第一个用于指示新的上行或下行数据传输的PDCCH所在的时隙是第三时间段的倒数第y个时隙。
如图22，若M＝minimum K0-1，Minimum K0＝3，M＝2，第三时间段的时长为M＝2个时隙。网络设备在第一不连续接收激活时间(也就是on duration)内没有发送用于指示新的下行数据传输的PDCCH，UE在第三时间段内继续监听PDCCH。网络设备在第三时间段内发送的PDCCH-1和PDCCH-2均指示了用于指示新的下行数据传输的PDCCH，其中PDCCH-1是第三时间段内的第一个用于指示新的下行数据传输的PDCCH，该PDCCH-1位于第三时间段的倒数第2个时隙，所以y＝2。由X＝M+1得知X＝3，所以第四时间段时长为X-y＝1个时隙，第四时间段的起始位置为第三时间段的结束位置。UE在第四时间段不监听PDCCH，而网络设备在第四时间段也不发送PDCCH。UE针对PDCCH-1传输的DCI译码成功之后会启动drx-InactivityTimer，此后UE重新进入不连续接收激活时间，即第二不连续接收激活时间。所以UE在第四时间段后继续监听PDCCH，网络设备也可以在第四时间段后继续发送PDCCH。
采用上述实施例，一旦网络设备在第一不连续接收激活时间的结尾(比如第一不连续接收激活时间的倒数第一个时隙)通过PDCCH调度了新的上行或下行数据传输，则网络设备在第一不连续接收激活时间之后就可以连续调度UE，UE在第一不连续接收激活时间之后的第三时间段继续监听PDCCH，所以UE并不会漏掉任何的PDCCH检测，这样既避免了网络设备和UE对第一不连续接收激活时间之后可能存在的一个时间段是否处于不连续接收激活时间理解不一致的问题，同时，在有数据收发时，网络设备也可以尽快的调度UE，减少了调度数据的时延。
可以理解的是，如上所描述的方法适用于PDCCH位于一个时隙的最开始的几个符号的情况，例如位于一个时隙的前S个符号，S＝1，或S＝2，或S＝3。该方法也适用于PDCCH位于一个时隙的中间的符号位置或结尾的符号位置的情况。当一个PDCCH位于一个时隙的中间符号或结尾符号时，即PDCCH的盲检搜索空间出现在一个时隙的中间符号或结尾 符号时，可以基于UE实现调整DCI的译码速度，使DCI译码仍然在n+X时隙之前完成。
但是，有些情况下，并不能保证在n+X时隙之前完成DCI译码。例如，指示新的上行或下行数据传输的第一DCI位于第一不连续接收时间的倒数第一个时隙的结尾的3个符号，而X＝minimum K0＝1，则第一DCI所在符号的结束符号与第一DCI所在时隙n的下一个时隙的起始符号之间没有时间间隔，自然UE无法在时隙n+1的起始时刻完成DCI译码。此时，UE译码第一DCI的时间也超过了第一不连续接收激活时间，根据如上描述的其中一个方法，例如，确定第三时间段的长度为X-y个时隙，其中y＝1，所以第三时间段时长为0，并不能解决由于DCI译码时间超过当前不连续接收激活时间造成网络设备和UE对不连续接收激活时间的理解不一致的问题，也不能使网络设备在有数据收发时尽快的调度UE。
为了避免此问题，可以约定，如果DCI位于一个时隙的结尾的S个符号位置，或者如果DCI不是位于一个时隙开始的S个符号位置(S＝1或2或3)，则规定第三时间段的时长为X+1-y个时隙，其中，X和y如之前描述，此处不再赘述。或者，规定第三时间段的时长为X个时隙，X如之前描述，此处不再赘述。
