信道监听方法、终端及网络设备
相关申请的交叉引用
本申请主张在2019年4月26日在中国提交的中国专利申请号No.201910346461.7的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信应用的技术领域，尤其涉及一种信道监听方法、终端及网络设备。
背景技术
对于空闲状态或者无线资源控制(Radio Resource Control，RRC)连接状态的每一个(Discontinuous Reception，DRX)周期，在DRX周期之前，基站首先传输一个唤醒信号给用户设备(User Equipment，UE)，UE在相应时刻醒过来检测该唤醒信号。若UE检测到该唤醒信号，则UE在DRX的激活期进行物理下行控制信道(Physical Downlink Control Channel，PDCCH)的监听；否则，该UE不在DRX的激活期进行PDCCH的监听，即跳过该DRX，继续休眠。
网络侧可以显式的通知UE醒来在DRX中进行接收，或者跳过该DRX，即无论UE是否需要唤醒，网络侧始终需要发送该PDCCH进行相应的指示，这样意味着较大的系统开销。
或者，只有在UE需要被唤醒时，网络才会进行唤醒信号的PDCCH的发送，如果UE在下一个DRX周期中不需要进行监听，网络可以不发送任何的PDCCH，从而降低网络的开销。这种情况下，如果UE没有成功接收唤醒信号,UE会错过后续的DRX的监听，将会导致较大的数据传输时延，那么需要考虑对PDCCH的传输和UE的监听进行增强，以保障唤醒信号的传输性能。
由上述描述可知，在配置了DRX和唤醒信号的情况下，如果UE接收传输唤醒信号的PDCCH不成功，那么会给业务传输带来较大的影响，因此，需要对PDCCH的传输进行增强，以保证终端接收PDCCH的唤醒信号的接收 性能。

如图2所示，本公开实施例提供了一种信道监听方法，应用于终端，包括：
步骤201：获得网络设备配置的物理下行控制信道PDCCH搜索空间，所述PDCCH搜索空间指示用于监听PDCCH的至少一个监听机会。
本公开实施例中，可通过无线资源控制RRC信令获取上述PDCCH搜索空间，该PDCCH搜索空间具体可用于指示监听机会的周期，在每个周期内的监听持续时间、在每个周期内的监听起始时刻和在预定时间段(如一个时隙slot)内的监听的起始OFDM符号中的至少一项。
步骤202：在所述监听机会中进行PDCCH的监听。
其中，所述PDCCH传输的信息用于指示以下至少一项：
所述终端在目标非连续接收DRX的持续时间内是否需要进行PDCCH的监听，目标DRX的持续时间为当前DRX的持续时间，或者当前时刻之后的Q个DRX的持续时间期间，Q为正整数；
所述终端进行带宽部分BWP切换；
所述终端进行对象的激活或去激活，所述对象为小区、小区群组、载波和载波群组中的至少一项；

所述终端进行上行的物理信道发送的功率控制参数和/或进行上行的物理信号发送的功率控制参数；
所述终端激活不同的DRX配置或下行控制信道搜索空间配置；

本公开实施例的信道监听方法，获得网络设备配置的物理下行控制信道PDCCH搜索空间，所述PDCCH搜索空间指示用于监听PDCCH的至少一个监听机会；在所述监听机会中进行PDCCH的监听。本公开实施例一方面能够保证网络设备传输PDCCH的灵活性，另一方面可以使得终端在PDCCH搜索空间中进行至少一次的监听，进而有效保证终端接收PDCCH的接收性能。
进一步地，在所述监听机会中进行PDCCH的监听，包括：
在所述监听机会的有效监听机会中进行PDCCH的监听；
所述有效监听机会满足以下至少一项条件：
有效监听机会所在的正交频分复用OFDM符号为除高层信令指示的上行符号和/或灵活flexible符号之外的符号；
有效监听机会所在的OFDM符号为除下行控制信息DCI指示的上行符号和/或灵活符号之外的符号；
有效监听机会所在的OFDM符号为除进行同步信号块SSB测量或信道状态信息参考信息CSI-RS测量之外的符号；
有效监听机会所在的OFDM符号与进行SSB测量的符号或进行CSI-RS测量的符号相邻。
进一步地，上述有效监听机会为网络设备指示的；
或者，在所述有效监听机会包括至少两个的情况下，所述至少两个有效监听机会为所述PDCCH搜索空间中连续的监听机会；
或者，所述有效监听机会为从监听起始时刻开始的一个或者连续多个监听机会。监听起始时刻可以由网络指示，例如，网络指示监听起始时刻相对于非连续接收的激活持续时间DRX Onduration的起始时隙的时间偏移。
如图3所示，假定网络设备配置的PDCCH搜索空间包括6个监听机会(monitoring occasion)，终端可以在该PDCCH搜索空间内的4个监听机会上进行监听，该4个监听机会可以是从监听起始时刻开始的4个监听机会或者网络设备指示的4个监听机会，例如，终端可以监听从监听起始时刻开始的前4个监听机会，放弃剩余的2个监听机会的监听。
进一步地，所述在所述监听机会中进行PDCCH的监听，包括：
在所述监听机会的聚合等级对应的前M个PDCCH候选，进行PDCCH的监听，M为正整数。
本公开实施例中，PDCCH候选(PDCCH candidate)可以包括1、2、4、8或16个控制信道粒子CCE，且不同的聚合等级对应的M值可以不同。
例如，终端需要监听聚合等级4和8的PDCCH，对于聚合等级4的PDCCH，可以只监听前4个PDCCH候选，对于聚合等级8的PDCCH可以只监听前2个PDCCH候选。
进一步地，在所述监听机会中进行PDCCH的监听，包括：
根据网络设备指示的所述监听机会的N个PDCCH候选的时间位置，进行PDCCH的监听，N为正整数。例如，网络配置的搜索空间在每个周期的一段持续时间内监听PDCCH的时间位置为8个，网络可以进一步指示可以在这8个时间位置中，只在其中的6个时间位置进行监听。本公开实施例中，可以直接由网络设备指示监听的PDCCH候选的时间位置，以便于终端进行监听。
进一步地，在所述监听机会中进行PDCCH的监听，包括：
在至少一个所述监听机会上使用相同的准共址QCL假设接收PDCCH。
这里，PDCCH包含PDCCH解调参考信号。
在所述至少一个监听机会上使用的QCL假设通过以下至少一种方式确定：
根据控制资源集合CORESET#0的QCL假设确定；
根据与CORESET0的激活传输配置指示TCI状态相同的QCL假设确定；
根据最近的随机接入过程中选取的SSB或者CSI-RS确定；
根据激活的带宽部分BWP上配置的CORESET中编号最低或最高的CORESET对应的激活TCI状态确定；
根据激活的BWP上配置的CORESET中网络指示的CORESET对应的激活TCI状态确定；
根据当前监听的搜索空间中目标搜索空间对应的CORESET对应的激活TCI状态确定，所述目标搜索空间为当前监听的所有搜索空间中监听周期最 低或者最高的搜索空间；
其中，激活的所述BWP上配置的CORESET是指除传输所述PDCCH所在的CORESET之外的CORESET。激活的所述BWP上配置的CORESET可以和传输所述PDCCH所在的CORESET在相同的BWP上，也可以在不同的BWP上。在本公开的具体实施例中，高层信令可以给每个UE配置4个BWP，在每个BWP上最多可以配置3个CORESET，每个CORESET可以通过RRC配置一个或者多个TCI state，如果配置了多个TCI state，那么网络通过媒体接入控制控制单元(MAC-CE)控制单元进行激活一个TCI state。
对于CORESET0，UE假设CORESET中的PDCCH接收的解调参考信号DMRS和如下信号准共址(quasi co-located，QCL)：
TCI state指示的一个或者多个下行参考信号(Reference Signal，RS)，其中，CORESET的TCI state是通过MAC-CE激活命令进行指示。
如果在最近发生的随机接入过程之后，UE没有收到激活CORESET0的TCI state MAC-CE命令，那么和最近发生的随机接入过程中UE识别的SSB准共址。该随机接入过程不是PDCCH命令触发的非竞争随机接入过程。
对于编号不为0的CORESET，如果只由高层信令配置了一个CORESET，或者UE收到MAC CE激活命令指示高层信令配置的该CORESET中的多个TCI state中的一个，UE假设CORESET中的PDCCH接收的解调参考信号(Demodulation Reference Signal，DMRS)和TCI state指示的一个或者多个下行RS准共址。
对于编号为0的CORESET，UE假设MAC-CE激活命令指示RS为CSI-RS，且该CSI-RS和SSB是typeD的准共址。
如果UE收到了MAC-CE激活命令指示激活多个TCI states中的一个，UE在反馈该MAC-CE的传输的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)对应的混合自动重传请求确认(HARQ-ACK)3ms之后使用这个激活的TCI state进行接收。
在本公开的具体实施例中，对于进行唤醒信号传输的PDCCH，网络可能配置一个带宽较窄的BWP，并在该BWP上配置一个CORESET进行该PDCCH的接收，或者网络直接配置一个带宽较窄的CORESET，在该 CORESET进行该PDCCH的接收。
当UE在该CORESET进行该PDCCH接收时，对PDCCH采用相同的TCI state，包括如下接收方式：
如果除了监听所述PDCCH的CORESET，UE只需要监听CORESET0，那么使用CORESET0的激活TCI-state进行接收；和/或，使用和最近的随机接入RACH过程中选取的关联SSB或者CSI-RS进行接收；
如果除了监听所述PDCCH的CORESET和CORESET0，还需要监听其他CORESET，则使用其它激活的CORESET中编号最低、最高或网络指示的CORESET对应的激活TCI state进行接收，和/或，使用当前监听的搜索空间中的监听周期最低或者最高的搜索空间对应的CORESET的激活TCI state进行接收。
进一步地，在所述监听机会中进行PDCCH的监听，包括：
在不同的监听机会中使用不同的QCL假设接收PDCCH。
这里，PDCCH包含PDCCH解调参考信号。
其中，所述QCL假设通过以下至少一种方式确定：
根据网络设备指示的PDCCH所在CORESET对应的至少一个TCI状态确定；
根据除PDCCH所在CORESET之外的CORESET对应的TCI状态确定；
根据监听机会和TCI状态标识ID的对应关系确定；
根据监听机会和CORESET ID的对应关系确定；
根据监听机会和CSI-RS资源编号的对应关系确定；
根据监听机会和SSB资源编号的对应关系确定。
在本公开的具体实施例中，对于进行唤醒信号传输的PDCCH，网络可能配置一个带宽较窄的BWP，并在该BWP上配置一个CORESET进行该PDCCH的接收，或者网络直接配置一个带宽较窄的CORESET，在该CORESET进行该PDCCH的接收。
该CORESET网络可以不配置TCI state，当UE在该CORESET进行该PDCCH接收时，对PDCCH采用不同的TCI state，包括如下至少一种接收方式：
网络指示这些WUS PDCCH所在CORESET对应的多个TCI state，例如，网络指示使用X个不同的TCI state进行该PDCCH的接收。如图4所示，指示第一个监听机会对应TCI状态1，第二个监听机会对应TCI状态2，第三个监听机会对应TCI状态3，第四个监听机会对应TCI状态4。
UE使用除WUS所在CORESET上的其它所有激活的CORESET的TCI state进行监听，例如，除了WUS的CORESET，还有3个激活的CORESET，那么UE使用这3个激活的CORESET的不同的TCI state进行该PDCCH的接收。这3个CORESET可以和监听WUS PDCCH的CORESET在相同的或者不同的BWP，如图5所示，第一个监听机会对应CORESET#1的TCI状态，第二个监听机会对应CORESET#2的TCI状态，第三个监听机会对应CORESET#3的TCI状态。
另外，图5所示的监听机会位于同一个搜索空间，当然，本公开实施例中的监听机会也可位于不同的搜索空间，如图6所示，第一个监听机会为搜索空间1中的监听机会，第二个监听机会为搜索空间2中的监听机会，第三个监听机会为搜索空间3中的监听机会，第一个监听机会对应CORESET#1的TCI状态，第二个监听机会对应CORESET#2的TCI状态，第三个监听机会对应CORESET#3的TCI状态。
具体监听时，UE可以在多个不同的监听机会上使用不同的TCI state进行监听，例如Monitoring occasion的时间顺序和CORESET ID或TCI state ID(或者根据CSI-RS/SSB资源的编号)的排序一一对应。例如UE需要在3个监听机会(monitoring occasion)上进行监听，同时CORESET#1，#2，#3是当前的激活的CORESET，那么在这3个monitoring occasion上分别使用CORESET#1，#2，#3对应的TCI state进行监听。
在频率范围2(Frequency range 2，FR2)，频率较高波长较短，通过间距较近的天线阵可以形成较窄的波束，网络通过发送波束赋形形成较窄的波束进行传输，UE可以通过收天线阵进行接收波束赋形，来提升传输性能。在激活的BWP上可以配置UE监听最多3个CORESET，每个CORESET的TCI state可以不同，即每个CORESET可以使用不同的收波束进行接收。在网络配置的DRX的情况下，由于UE在DRX的非激活期不进行波束跟踪和调整， 导致网络配置和激活的CORESET对应的TCI state对应的接收波束不一定能达到的很好的性能，如果只监听其中的一个CORESET，即只使用其中的一个收波束进行接收，在信道环境变换的情况下不一定能保证接收性能，而本公开实施例的信道监听方法，通过配置终端在多个监听机会上进行监听，一方面使得网络获得了传输控制信道的灵活性，另外一方面可以实现UE在多个监听机会的相同或者不同波束的多次监听，获得较好的接收性能，且本公开实施例能够保证终端在较短的时间内完成PDCCH的监听，有利于降低终端的功耗。
如图7所示，本公开的实施例还提供了一种信道监听方法，应用于网络设备，该方法包括：
步骤701：配置物理下行控制信道PDCCH搜索空间，所述PDCCH搜索空间指示用于监听PDCCH的至少一个监听机会。

该PDCCH搜索空间具体可用于指示监听机会的周期，在每个周期内的监听持续时间、在每个周期内的监听起始时刻和在预定时间段(如一个时隙slot)内的监听的起始OFDM符号中的至少一项。

进一步地，所述配置物理下行控制信道PDCCH搜索空间之后，还包括：
向终端指示有效监听机会，所述有效监听机会为终端进行PDCCH监听的监听机会。
或者，如果网络没有指示有效的监听机会，所述有效监听机会满足以下至少一项条件：

有效监听机会所在的OFDM符号为除进行同步信号块SSB测量或信道状态信息参考信息CSI-RS测量之外的符号；
有效监听机会所在的OFDM符号与进行SSB测量的符号或进行CSI-RS测量的符号相邻。
在本公开的具体实施例中，在所述有效监听机会包括至少两个的情况下，所述至少两个有效监听机会为所述PDCCH搜索空间中连续的监听机会；
或者，所述有效监听机会为从监听起始时刻开始的一个或者连续多个监听机会。
进一步地，所述配置物理下行控制信道PDCCH搜索空间之后，还包括：
向终端指示监听的每个聚合等级对应的PDCCH候选的数目。
本公开实施例中，PDCCH候选(PDCCH candidate)可以包括1、2、4、8或16个控制信道粒子CCE，且不同的聚合等级对应的M值可以不同。
例如，终端需要监听聚合等级4和8的PDCCH，对于聚合等级4的PDCCH，可以只监听前4个PDCCH候选，对于聚合等级8的PDCCH可以只监听前2个PDCCH候选。
进一步地，所述配置物理下行控制信道PDCCH搜索空间之后，还包括：
