  • PDCCH physical downlink control channel
  • the system can configure a short cycle (short DRX cycle) or a long cycle (long DRX cycle) for the UE according to different service scenarios. For example, when a VOIP service is performed, the voice codec usually sends a VOIP packet in 20ms, so a short DRX cycle with a length of 20ms can be configured, and a long silent period during a voice call can be configured with a long DRX cycle. If both short cycle and long cycle are configured and the DRX short cycle timer expires, the UE will enter a long DRX cycle. Conversion of DRX long and short cycles:
  • Case 1 The UE receives the PDCCH in the On Duration timer interval, which will trigger the DRX-inactivity timer; if the DRX-inactivity timer times out, it will trigger the DRX short cycle timer; if the DRX-short cycle timer times out, the long DRX cycle will be used.
  • the role of the DRX-inactivity timer is to reduce the data processing delay, but if the duration of the DRX-inactivity timer is set too long, the UE will continue to monitor the downlink subframes and the timer has not timed out after the data is sent from the network side. Can't go to sleep in time. In order to quickly put the UE into the sleep state, the system introduces a DRX-related media access control layer-control element (MAC CE). When the UE receives the DRX control element, it will stop On Duration timer and DRX-inactivity timer, enter DRX.

  • the specific process is as follows: if the UE receives a DRX command (command) MAC CE or a long DRX command MAC CE, it stops the drx-on duration timer, or stops the DRX-inactivity timer. If a DRX Command MAC CE is received, if a short DRX cycle is configured, start or restart the DRX-short cycle timer in the first symbol after receiving the DRX Command MAC CE, and start using the short DRX cycle; otherwise, Start using the long DRX cycle.

本申请主张在2020年09月25日在中国提交的中国专利申请号202011027660.0的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种信道监测方法、装置及用户设备。
背景技术
在通信系统中，用户设备(user equipment，UE)在监测物理下行控制信道(physical downlink control channel，PDCCH)时，可以通过不连续接收(discontinuous reception，DRX)的方式，周期性地监测PDCCH，以接收下行数据或上行授权信息等。即UE周期性地在某些时候进入睡眠状态(sleep mode)，不监测PDCCH，而需要监测的时候，则从睡眠状态中唤醒(wake up)，监测并接收PDCCH，这样就可以使得UE达到省电的目的。
然而，上述过程中，由于在UE处于睡眠状态时，可能也会有数据需要传输，而此时UE并不进行PDCCH的监测，而是在切换到唤醒状态之后，才进行PDCCH的监测，因此会造成数据传输的延时，从而导致数据传输的性能较差。
发明内容
本申请实施例提供一种信道监测方法、装置及用户设备，能够实现灵活监测PDCCH，提高数据传输的性能。
第一方面，本申请实施例提供了一种信道监测方法，该信道监测方法包括：UE接收网络设备发送的第一信息，该第一信息用于指示UE对下行控制信道的监测行为，该第一信息包括以下至少一项：时间信息和频域信息；UE根据第一信息，监测或停止监测目标下行控制信道。
第二方面，本申请实施例提供了一种信道监测装置，该信道监测装置包括：接收模块和处理模块。其中，接收模块，用于接收网络设备发送的第一信息，该第一信息用于指示UE对下行控制信道的监测行为，该第一信息包括以下至少一项：时间信息和频域信息。处理模块，用于根据接收模块接收的第一信息，监测或停止监测目标下行控制信道。
第三方面，本申请实施例提供了一种UE，该UE包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的程序或指令，所述程序或指令被所述处理器执行时实现如第一方面所述的信道监测方法的步骤。
第四方面，本申请实施例提供了一种可读存储介质，所述可读存储介质上存储程序或指令，所述程序或指令被处理器执行时实现如第一方面所述的信道监测方法的步骤。
第五方面，本申请实施例提供了一种芯片，所述芯片包括处理器和通信接口，所述通信接口和所述处理器耦合，所述处理器用于运行程序或指令，实现如第一方面所述的信道监测方法。
在本申请实施例中，UE可以根据网络设备发送的第一信息，监测或停止监测目标下行控制信道。由于UE在监测下行控制信道时，可以根据网络设备的动态指示，灵活地在时间上和频域上监测相应的下行控制信道，避免未监测下行控制信道，而导致数据传输延时，从而在节省UE耗电的同时，提高了数据传输的性能。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面对本申请实施例提供的信道监测方法、装置及用户设备中涉及的一些概念和/或术语做一下解释说明。
无线资源控制(radio resource control，RRC)连接态(RRC-connected)下的DRX：DRX周期(cycle)由“On Duration”和“Opportunity for DRX”组成。在“On Duration”的时间内，UE监听并接收物理下行控制信道(physical downlink control channel，PDCCH)；在“Opportunity for DRX”时间内，UE不监听PDCCH，以节省功耗。如果在“On Duration”内接收到了新传输的PDCCH，那么会启动或重启定时器(inactivity timer)来延长UE监听PDCCH的时长。
DRX的长、短周期：系统可以根据不同的业务场景，给UE分别配置短周期(short DRX cycle)或者长周期(long DRX cycle)。例如，在进行VOIP业务时，语音编解码器通常20ms发送一个VOIP包，那么就可以配置长度为20ms的DRX短周期，而在语音通话期 间较长的静默期，就可以配置DRX长周期。如果同时配置了短周期和长周期，且DRX短周期定时器超时，那么UE将进入一次长DRX周期。DRX长短周期的转换：
情况1：UE在On Duration timer区间接受到PDCCH，会触发DRX-inactivity timer；DRX-inactivity timer超时，会触发DRX short cycle timer；DRX-short cycle timer超时，会使用long DRX cycle。
情况2：如果在长DRX接收到PDCCH，会触发使用short DRX。
DRX-inactivity timer的作用是为了降低数据的处理时延，但如果DRX-inactivity timer的时长设置的过长，当网络侧的数据发送完之后定时器还没有超时，则UE继续监听下行子帧，无法及时的进入睡眠状态。为了快速地让UE进入睡眠状态，系统引入了一个与DRX相关的媒体接入控制层控制单元(media access control layer-control element，MAC CE)，当UE收到这个DRX控制单元之后，将停止On Duration timer和DRX-inactivity timer，进入DRX。具体流程如下：UE如果接收到DRX命令(command)MAC CE或long DRX command MAC CE，那么停止drx-on duration timer，或者停止DRX-inactivity timer。如果接收到的是DRX Command MAC CE，若配置了short DRX cycle，在DRX Command MAC CE接收结束后的第一个符号中启动或重新启动DRX-short cycle timer，并开始使用short DRX cycle；否则，开始使用long DRX cycle。如果DRX-short cycle timer到期，则使用长DRX周期。如果接收到的是long DRX command MAC CE，则停止DRX-short cycle timer，并开始使用长DRX周期。
可以看出，目前支持的DRX command MAC CE来终止DRX-on duration timer，DRX-inactivity timer，对于long DRX command MAC CE，还可以终止L个(L≥1，由DRX-short cycle timer决定)short DRX cycle，由此UE可以终止活动时间直到下一个DRX周期的on duration进入活动时间，开始监测PDCCH。但是，DRX command MAC CE不能在一个或K(K<L)个short DRX间进行更加动态的PDCCH监测控制、调整。
DCP：分组交换无线网络临时标识符(packet switch-radio network tempory identity)加扰的DCI 2-6(DCI format 2_6with CRC scrambled by PS-RNTI)。为了在DRX配置下进一步节能，网络侧可以在配置了连接态的(connected DRX，C DRX)机制下，给UE进一步配置DCP。DCP中唤醒指示(wake Up indication)域用于指示UE是否开启下一个DRX周期onduration Timer或DCP指示MAC层是否开启下一个DRX周期onduration Timer，启动timer意味着UE要在timer内监听PDCCH，反之不监听PDCCH。
目前DCI format 2-6的两个信息域：
唤醒指示(1bit)这个域就是指示UE是否开启下一个DRX周期的on duration timer的；
辅小区休眠指示(Scell dormancy indication)(0，1，2，3，4，5bits)这个域是用来指示载波聚合(carrier aggregation，CA)下，UE的SCell是否进入休眠行为的。此外，DCI2-6中SCell休眠指示域用于以SCell组(group)为单位来指示SCell组是否切换到休眠带宽部分(bandwidth part，BWP)。该域中每个比特对应指示一个SCell组。
激活期内的SCell休眠指示：可以在激活期内通过调度DCI格式来进行Scell休眠指示。一种情况，通过DCI format 1-1，0-1来同时调度物理下行共享信道(physical downlink shared channel，PDSCH)、物理上行共享信道(physical uplink shared channel，PUSCH) 和SCell休眠指示。另一种情况，通过DCI format 1-1进行SCell dormancy indication且不调度PDSCH。
相同时隙调度(same slot scheduling)：当前时隙的PDCCH调度相同时隙的PDSCH。UE接收两个符号的PDCCH后，需要额外的处理时间进行解调PDCCH以得到PDCCH传输的下行控制信息(downlink control information，DCI)，包括(resource block，RB)分配信息等，因此在得到RB分配信息之前，UE需要缓存整个带宽/BWP的PDSCH。
跨时隙调度(cross-slot scheduling)：当前slot的PDCCH调度后续不同slot的PDSCH。如果UE可以预设获知其不会被调度接收或发送的时间范围，则UE能够将其射频(radio frequency，RF)和部分前端硬件以及其他调制解调器硬件置于节省功率模式的状态。例如UE接收两个符号的PDCCH后，有足够时间进行解码(decoding)以得到PDCCH传输的内容(DCI)，包括RB分配信息等，因此UE只需要在相关的RB上接收对应的PDSCH。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(long term evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(code division multiple access，CDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency division multiple access，OFDMA)、单载波频分多址(single-carrier frequency-division multiple access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(new radio，NR)系统，并且在以下大部分描述中使用NR术语，这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
示例性的，图1示出了本申请实施例提供的一种通信系统的架构示意图。如图1所示，该通信系统可以包括UE 01和网络设备02。其中，UE 01与网络设备02之间可以建立连接并通信。
本申请实施例中的UE也可以称作终端设备，UE可以是手机、平板电脑(tablet personal computer)、膝上型电脑(laptop computer)或称为笔记本电脑、个人数字助理(personal digital assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(mobile internet device，MID)、可穿戴式设备(wearable device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定UE的具体类型。
本申请实施例中的网络设备可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(base transceiver station，BTS)、无线电基站、无线电收发机、基本服务集(basic service set，BSS)、扩展服务集(extended service set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(transmitting receiving point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的信道监测方法进行详细地说明。
本申请实施例中，通过下行控制信道的监测相关信令(例如下述实施例所述的第一信息)，动态的定义UE监测下行控制信道的行为。UE可以根据该监测相关信令，跳过下行控制信道的监测(即不监测相应的下行控制信道)，或者监测相应的下行控制信道，从而实现灵活地对下行控制信道的监测，避免未及时监测下行控制信道导致数据传输延时。

需要说明的是，针对上述步骤301与步骤203的执行顺序，本申请实施例不作限制。一种方式，可以先执行上述步骤203，再执行上述步骤301，即可以先根据第一信息，监测或停止监测目标下行控制信道，再监测第二下行控制信道；另一种方式中，可以先执行上述步骤301，再执行上述步骤203，即可以先监测第二下行控制信道，再根据第一信息，监测或停止监测目标下行控制信道；又一种方式中，可以同时执行上述步骤203和步骤301，即可以在根据第一信息，监测或停止监测目标下行控制信道的同时，监测第二下行控制信道。
可选地，本申请实施例中，上述步骤203具体可以通过下述的步骤203a实现。
步骤203a、在满足预设条件的情况下，UE根据第一信息，监测或停止监测目标下行 控制信道。
本申请实施例中，上述预设条件包括以下至少一项：UE所在小区为辅小区、UE所在小区为跨载波调度主小区的辅小区、UE所在小区对应的频率在目标频率范围内、UE处于目标状态、UE根据其他监测相关信息监测下行控制信道、下行控制信道对应的载波单元上的BWP处于非休眠状态。
需要说明的是，上述其他监测相关信息可以理解为：用来监测下行控制信道的信息，根据该其他监测相关信息执行监测下行控制信道，可以达到UE节省耗电的目的。
可选地，本申请实施例中，上述其他监测相关信息包括以下至少一项：DRX周期相关信息、WUS、跨时隙调度(cross-slot scheduling)指示信息、辅小区休眠指示信息(SCell dormancy indication)。
可选地，本申请实施例中，上述DRX周期相关信息可以包括以下至少一项：DRX非激活时间(inactivitity Timer)信息、HARQ往返时延时间(RTT Timer)信息、重传时间(retransmission timer)信息。
可选地，本申请实施例中，上述PDCCH skipping信令也可以适用于所有的小区，即UE在辅小区、主小区(PCell)、主辅小区(PSCell)或PUCCH辅小区(PUCCH SCell)，都可以根据第一信息，监测或停止监测目标下行控制信道。例如，若UE处于主小区或主辅小区，则UE可以停止监测主小区或主辅小区上的PDCCH监测，并继续监测或不监测其他辅小区上的PDCCH，或者，UE可以继续监测主小区或主辅小区所在的小区组中所有小区上的PDCCH。
示例性的，如图3所示，作用于PCell、PSCell或PUCCH SCell的PDCCH跳过(skipping)信令，UE跳过相应的短DRX周期(short DRX cycle)或长DRX周期(long DRX cycle)中的DRX激活时间(on duration timer)中PDCCH的监测。例如，在DRX短周期时间(DRX short cycle timer)内跳过第一个短DRX时间内的PDCCH监测(即skip 1st short DRX within DRX-short cycle timer)；在DRX短周期时间(DRX short cycle timer)内跳过第二个短DRX和长DRX周期时间内的PDCCH监测(即skip 2nd short DRX within DRX-Short cycle timer and long DRX cycle)。
示例性的，如图4所示，示出了同一小区组中的Scell受到PCell、PSCell、PUCCH SCell的影响，即根据PDCCH跳过信令，跳过DRX激活时间(on duration timer)中PDCCH的监测。
示例性的，如图5所示，示出了同一小区组中的Scell不受到PCell、PSCell、PUCCH SCell的影响，即不跳过DRX激活时间(on duration timer)中PDCCH的监测。
可选地，本申请实施例中，UE可以停止监测辅小区(SCell)上的PDCCH，并继续监测主小区或主辅小区上的PDCCH。
可选地，本申请实施例中，对于动态频谱共享(dynamic spectrum sharing，DSS)，即主小区可以被辅小区跨载波调度的场景，PDCCH skipping信令不适用于可以跨载波调度主小区的辅小区。
可选地，本申请实施例中，上述目标状态可以为以下任一项：连接态(RRC-connected state)、空闲(idle)态、非激活(inactive)态。
可选地，本申请实施例中，PDCCH skipping信令可以应用于支持小数据(small data) 或提早数据(early data)传输的UE(空闲态下或非激活态下的UE)。
可选地，本申请实施例中，PDCCH skipping信令可以应用于DSS中的联合DCI(joint DCI)，即联合DCI调度多个CC。
需要说明的是，在PDCCH skipping信令适用于处于空闲态下或非激活态下的UE的情况下，该PDCCH skipping信令可以指示支持小数据或提早数据发送的UE(空闲态下或非激活态下的UE)是否继续监测调度小数据或提早数据的PDCCH。在PDCCH与DCI-based WUS结合、且用于处于空闲态下或非激活态下的UE的情况下，PDCCH skipping信令也可以指示是否跳过寻呼(paging)PDCCH的监测。
可选地，本申请实施例中，若PDCCH skipping信令作用于一组CC(多个CC)，若有的CC上当前激活的(active)BWP是休眠/睡眠(dormant)态BWP，则UE忽略该PDCCH skipping信令，即该PDCCH只作用于当前active BWP是非休眠(non-dormant)态BWP的CC。
可选地，本申请实施例中，若PDCCH skipping信令作用于一个CC，则该PDCCH skipping不应该指示当前active BWP是休眠的BWP的CC，即若UE接收到这样的PDCCH skipping信令，视为错误信息。
示例性的，如图6所示，示出了一个PDCCH跳过(skipping)信令作用于多个CC，支持跨载波指示，即针对多个CC，通过发送一个PDCCH跳过信令，以使得该多个CC都可以基于该PDCCH跳过信令跳过PDCCH的监测。例如，在小区#1中发送一个PDCCH跳过信令，便可以作用于小区#1、小区#2和小区#3，以使得这些小区中的UE都可以基于该PDCCH跳过信令，跳过指定的时间(例如DRX激活时间(on duration timer))、频率范围上指定的PDCCH的监测。
示例性的，如图7所示，示出了一个PDCCH跳过(skipping)信令作用于1个CC，支持自载波指示，即针对多个CC，通过发送多个PDCCH跳过信令(即每个CC分别对应一个PDCCH跳过信令)，以使得该多个CC基于对应的PDCCH跳过信令跳过PDCCH的监测。例如，在小区#1中发送一个PDCCH跳过信令，可以作用于小区#1，以使得小区#1中的UE可以基于该PDCCH跳过信令，跳过指定的时间(例如DRX激活时间(on duration timer))、频率范围上指定的PDCCH的监测。针对小区#2和小区#3，与小区#1的过程类似，此处不再赘述。
本申请实施例中，第一信息可以应用于主小区或主辅小区，或者独立于DRX工作，实现在节省UE耗电的同时保证UE的性能。
可选地，本申请实施例中，上述步骤203具体可以通过下述的步骤203b或步骤203c实现。
步骤203b、在UE未发起基于竞争的随机接入过程的情况下，UE根据第一信息，监测或停止监测目标下行控制信道。

可选地，本申请实施例中，上述步骤203c可以替换为下述的步骤203d。
步骤203d、在UE发起了基于竞争的随机接入过程、且未接收到采用特定RNTI加扰的下行控制信道调度的随机接入消息(例如Msg4)的情况下，UE忽略第一信息。
需要说明的是，UE忽略第一信息可以理解为：UE并不根据第一信息的指示，执行监测或停止监测目标下行控制信道。
可选地，本申请实施例中，在UE发起了基于竞争的随机接入过程、且未接收到采用特定RNTI加扰的下行控制信道调度的随机接入消息，或者UE发起了非竞争的随机接入的情况下，UE也可以不期望在指示跳过的PDCCH上接收到采用特定RNTI加扰的PDCCH调度的随机接入消息。

本申请实施例中，在时间上可以实现在一个或多个连续的或者不连续的短DRX周期间进行更加动态的下行控制信道监测控制、调整；在频域上可以实现一个或多个CC的下行控制信道监测控制、调整。
本申请实施例提供一种信道监测方法，UE可以根据网络设备发送的第一信息，监测或停止监测目标下行控制信道。由于UE在监测下行控制信道时，可以根据网络设备的动态指示，灵活地在时间上和频域上监测相应的下行控制信道，避免未监测下行控制信道，而导致数据传输延时，从而在节省UE耗电的同时，提高了数据传输的性能。
可选地，本申请实施例中，在上述步骤202之后，本申请实施例提供的信道监测方法还包括下述的步骤401。
步骤401、在UE所在小区为目标小区的情况下，UE传输第三信息。

可以理解，若UE传输了CG PUSCH和/或SPS PDSCH without PDCCH，UE可以开启上行和/或下行的目标计时器，在目标计时器运行时间内监测可能调度重传的PDCCH，该重传PDCCH所在的搜索空间类型没有限制，或者该重传PDCCH所在的搜索空间为第二预设类型CSS(例如type 0、type 0A、type 1或type 2)CSS。并且，该重传PDCCH是除了PDCCH skipping信令指示跳过的PDCCH的其他PDCCH，或者该PDCCH传输在新引入的回退(fallback)/PDCCH-skipping free的PDCCH搜索空间。
可选地，本申请实施例中，无论UE是否开启上行和/或下行的目标计时器，在目标计时器的运行时间内，UE都不再监测可能调度重传的PDCCH。
可以理解，若UE传输了SR，则UE监测PDCCH，该PDCCH所在的搜索空间类型没有限制,或者该重传PDCCH所在的搜索空间为第二预设类型CSS。并且，该重传PDCCH是除了PDCCH skipping信令指示跳过p的PDCCH的其他PDCCH，或者该PDCCH传输在新引入的fallback/PDCCH-skipping free的PDCCH搜索空间。
需要说明的是，对于fallback或PDCCH-skipping free的PDCCH搜索空间：PDCCH skipping信令不作用于传输在该PDCCH搜索空间上的PDCCH，该搜索空间是UE特定的搜索空间(UE-specific search space)。
可选地，本申请实施例中，当MAC层定时器的开启或者MAC层的过程，导致UE处于DRX active time和/或UE需要监测PDCCH时，UE在该fallback/PDCCH-skipping free的PDCCH search space监测PDCCH。
