Description

唤醒信号的同步源的确定方法、终端及网络侧设备
交叉引用
本申请要求在2022年08月03日提交中国专利局、申请号为202210929228.3、名称为“唤醒信号的同步源的确定方法、终端及网络侧设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于无线通信技术领域，具体涉及一种唤醒信号的同步源的确定方法、终端及网络侧设备。
背景技术
在新空口(New Radio，NR)系统中，为了进一步提高用户设备(User Equipment，UE)的省电性能，引入了基于物理下行控制信道(Physical downlink control channel，PDCCH)的唤醒信号(Wake Up Signal，WUS)。WUS的作用是告知UE在特定的非连续接收(Discontinuous Reception，DRX)的持续时间(onDuration)期间，是否需要监听PDCCH。UE根据该指示，决定下一个DRX周期是否启动onDuration定时器，以及是否进行PDCCH监听。当没有数据的情况，UE可以不需要监听onDuration期间的PDCCH，相当于UE在整个DRX长周期(Long cycle)中都可以处于休眠状态，从而更进一步的省电。
网络侧设备(例如，基站)可以基于节能的目的，进入某些节能模式。比如，可以关闭基站部分或全部的上行传输和/或下行传输，并使基站持续监控来自终端UE或其它设备的唤醒信号(WUS)。当处于节能模式的基站接收到唤醒信号后，可以再转入其它基站工作状态，例如，基站完全开启，或转为浅度节能工作模式等。
在现有技术中，唤醒信号是由基站发送给UE的(即下行WUS，DL WUS)，由于基站本身也是UE驻留在小区的同步源，所以DL WUS的同步源必然与UE小区同步源是一体的。然而，对于UE发送给基站的WUS(即上行WUS，UL WUS)，根据UL WUS可能的使用场景的不同，UL WUS的接收对象可能是服务小区、有目标的节能小区、或任意节能小区。由于不同的小区之间并不一定会同步，所以UE如何确定UL WUS的同步源是 目前需要解决的技术问题。

在本申请实施例中，可选的，所述WUS配置信息包括以下至少一项：
(1)同步源信息，用于指示WUS的至少一个同步源。
在本申请实施例中，WUS的同步源可以是基站、卫星、终端等设备(类型)，或服务小区、节能小区、服务小区或节能小区的关联小区、NTN小区等逻辑实体。
在本申请实施例中，同步源信息可以包含同步源的具体配置信息，例如，标识信息、时频域信息等。
(2)优先级信息，用于指示各个所述同步源的优先级。
通过该优先级信息，终端可以确定各个同步源的优先级。
(3)第一时长信息，用于指示各个所述同步源的失步判断时长。
即同步源的失步判决时长Tout-of-sync。例如，UE在T0时刻收到某同步源的同步信号，若此后UE在[T0,T1]时刻内都没有收到该同步源的同步信号，则UE认为与该同步源发生失步。所述同步源的失步判决时长可以定义为Tout-of-sync＝T1-T0。
(4)有效时间信息，用于指示各个所述同步源的有效时间。
所述同步源的有效时间Tsync-valid指示UE以某同步源作为UE发送WUS的同步源时，同步源为有效同步源的时间，在所述时间内，UE仍可以以所述同步源的校准时时(即校时)发送WUS。
(5)时间差信息，用于指示所述至少一个同步源中两个同步源之间的校准时间差。
时间差信息可以指示两个WUS同步源之间的校时时间差。例如，若第一WUS同步源与第二WUS同步源之间的时间差为Toffset，则UE可以通过与第一WUS同步源同步，获得第二WUS同步源的校时，反之同理。
在申请实施例中，第一WUS配置信息可以是网络侧设备为终端配置的，例如，终端的服务小区向终端发送第一WUS配置信息，或者，第一WUS配置信息也可以包含同步源的小区配置信息中。例如，小区1是UE的服务小区，小区1给UE配置了小区2是一个同步源(即小区给UE发送的第一WUS配置信息中指示小区2是一个可选的同步源)，或者小区2的小区配置信息(CellConfig)里包含第一WUS配置信息(WUS Config)。
S220，所述终端根据所述第一WUS配置信息，确定上行唤醒信号的同步源为第一同步源。
在本申请实施例中，所述终端可以根据所述第一WUS配置信息，确定上行WUS的同步源为第一同步源。例如，在所述第一WUS配置信息中的同步源信息只指示WUS的一个同步源的情况下，终端确定该同步源为WUS的同步源(即第一同步源)。在所述第一WUS配置信息中的同步源信息指示WUS的多个同步源情况下，终端可以结合第一WUS配置信息中的优先级信息，获取WUS的第一同步源，例如，选择多个同步源中优先级最高的同步源作为第一同步源。又例如，UE选择多个同步源中可以检测到同步信号的多个同步源中的优先级最高的同步源作为第一同步源。
通过本申请实施例提供的技术方案，终端接收网络侧设备发送的第一WUS配置信息，根据所述第一WUS配置信息，确定上行WUS的同步源为第一同步源，从而可以在需要发送WUS时，确定发送上行WUS的同步源，进而实现上行WUS的发送，节省网络侧设备的功耗。
在一个可能的实现方式中，如图3所示，该方法还可以包括：S230，所述终端根据所述第一同步源的时间进行时间对齐。例如，终端可以通过与第一同步源同步，获取校准时间，进而与第一同步源的时间进行时间对齐。
在一个可能的实现方式中，该方法还可以包括：终端可以按照第一同步源对应的第一WUS配置信息发送WUS，例如，终端在通过S230进行时间对齐之后，可以按照第一同步源对应的第一WUS配置信息发送WUS。
例如，第一WUS配置信息中可以包括WUS配置，用于指示与一个或多个所述同步源对应的WUS配置，所述WUS配置包括：WUS的时频域信息、WUS的周期、WUS的信号特征、WUS的最大发送次数、WUS的生效区域。
通过WUS配置，UE可以确定发送WUS的相关信息，例如，终端确定使用第一同步源作为发送WUS的同步源，则在发送WUS时，可以使用与第一同步源对应的第一WUS配置信息中的WUS配置发送WUS，例如，在该WUS配置中的时频域信息指示是时频域位置发送WUS，或者，按照该WUS配置中的WUS的周期，周期性的发送WUS等。
在一个可能的实现方式中所述终端根据所述第一同步源的时间进行时间对齐，包括：所述终端在所述第一同步源的有效时间内，所述终端根据所述第一同步源的时间进行时间对齐。通过该可能的实现方式，在第一同步源的有效时间内，根据所述第一同步源的时间进行时间对齐，可以保证终端与网络侧进行时间同步的准确性。
在一个可能的实现方式中，终端可以通过以下步骤确定所述第一同步源的有效时间：
步骤1，所述终端在第一时刻T0接收到所述第一同步源的同步信号；
步骤2，在第一时刻T0之后，直至第二时刻T1，所述终端均未接收到所述第一同步源同步信号的情况下，所述终端确定在第三时刻T2之后禁止发送上行唤醒信号，并确定所述第一同步源的有效时间为：T2-T1；或者，T2-T0。
例如，UE在T0时刻收到某同步源的同步信号，若此后UE在[T0,T1]时刻内都没有收到该同步源的同步信号，则UE认为与该同步源发生失步。此后，UE在[T1,T2]时间内仍可以发送WUS，但在T2时间后认为该禁止发送WUS。所述有效时间的定义可以是：
Tsync-valid＝T2-T1；或
Tsync-valid＝T2-T0。
需要说明的是，T2可以等于T1，此时WUS同步源有效时间即等于WUS同步源的失步判决时长。
在另一个可能的实现方式中，如果UE处于连接态，则终端可以通过以下方式确定第一同步源的有效时间：连接态的所述终端在第四时刻T3判断发生无线链路失败(Radio Link Failure，RLF)，确定第五时刻T4之后禁止发送上行唤醒信号，并确定所述第一同步源的有效时间为T4-T3。
例如，当连接态的UE在T3时刻判断发生RLF时，则UE在[T3,T4]时间内仍可以发送WUS。WUS同步源有效时间可定义为：
Tsync-valid＝T4-T3。
其中，终端可以基于某些原因的判断，确认对于当前的服务小区处于RLF状态，比如：
(1)无线链路监测定时器T310超时，UE处于持续的out-of-sync状态；
(2)波束失败恢复(Beam Failure Recovery，BFR)失败；
(3)随机接入问题；
(4)无线链路控制(Radio Link Control，RLC)重传次数超出；
(5)先听后说(Listen Before Talk，LBT)失败。
在一个可能的实现方式中，该方法还可以包括：所述终端确定与所述第一同步源发生失步。由于终端可能处于移动状态，因此，在确定第一同步源为上行唤醒信号的同步源之后，终端可能与第一同步源发生失步，终端通过判断是否与第一同步源发生失步，可以保证获取的发送WUS的时间与网络侧的同步。
在一个可能的实现方式中，终端可以在以下至少之一的情况下，确定与第一同步源发生失步：
(1)所述终端的无线链路监测定时器T310超时，其中，所述终端处于连接态，例如RRC连接态的UE。
当UE从物理层收到第N个out-of-sync指示时，UE启动T310计时器，当T310计时器超时，UE判决与同步源发生RLF，所述N为正整数；这种情况下RLF可视为UE与同步源发生失步。
(2)所述终端在预定时间段内未接收到所述第一同步源发送的同步信号，其中，所述终端处于非连接态，例如，空闲态的UE，或者非激活态的UE。
例如，UE在T0时刻收到某同步源的同步信号，若此后UE在[T0,T1]时刻内都没有收到该同步源的同步信号，则UE在
T1时刻判决与WUS同步源发生失步。
在一个可能的实现方式中，所述方法还包括：在确定与所述第一同步源发生失步的情况下，所述终端执行以下之一：
(1)所述终端停止发送WUS。即终端在确定与第一同步源发生失步后，立即停止发送WUS。
(2)所述终端在所述第一同步源的有效时间内继续发送WUS；即终端在确定与第一同步源发生失步后，并不立即停止发送WUS，而是在第一同步源的有效时间内继续发送WUS。
(3)所述终端在所述第一同步源的有效时间后停止发送WUS。即终端在确定与第一同步源发生失步后，并不立即停止发送WUS，而是在第一同步源的有效时间后停止发送WUS。
在一个可能的实现方式中，所述方法还可以包括：在第二情况下，所述终端确定第二同步源为上行唤醒信号的同步源。也就是说，在第二情况下，终端可以变更WUS的同步源。例如，在所述终端根据所述第一WUS配置信息，确定第一同步源为上行唤醒信号的同步源之后，在第二情况下，终端变更上行WUS的同步源为第二同步源。
可选的，所述第二情况包括但不限于以下至少之一：
(1)所述终端检测到优先级高于所述第一同步源的第二同步源。
例如，当UE检测到更高优先级的WUS同步源(的同步信号)，UE向更高优先级的WUS同步源进行校时。
(2)所述终端确定与所述第一同步源发生失步。
例如，当UE判决与当前的WUS同步源发生失步，UE可以向与当前的WUS同步源相同或更低优先级的WUS同步源进行校时。
其中，终端确定与第一同步源发生失步的方式可以参见上述相关的描述。
(3)所述终端与小区发生了RLF，其中，所述终端处于连接态。
例如，当UE从物理层收到第N个out-of-sync指示时，UE启动T310计时器，当T310计时器超时，UE判决与同步源发生RLF，所述N为正整数；这种情况下RLF可视为UE与同步源发生失步。
(4)所述终端确定所述第一同步源失效。
例如，终端可以按照上述确定所述第一同步源的有效时间的方式确定第一同步源的有效时间，UE在第一同步源的有效时间内仍可发送WUS，但超过有效时间之后就不能发送WUS了。此时UE应进行WUS同步源的变更。
(5)所述终端确定当前的地理位置与所述第一同步源的地理位置之间的距离超过第一阈值。
当UE判决当前自己的地理位置与第一同步源的地理位置的距离超过某个阈值，UE认为离开了当前已离开第一同步源的生效范围，则UE认为第一同步源不可用，可以向其它同步源进行校时。
(6)所述终端确定当前的地理位置与所述第一同步源的参考地理位置之间的距离超过第二阈值。
在某些情况下，第一同步源可能是覆盖某个范围，例如，第一同步源为节能小区，可以通过参考地理位置对第一同步源进行定位，因此，在该可能的实现方式中，当UE判决当前自己的地理位置与第一同步源的参考地理位置的距离超过某个阈值，UE认为离开了 当前已离开第一同步源的生效范围，则UE认为第一同步源不可用，可以向其它同步源进行校时。
当UE使用网络侧设备为第一同步源配置的WUS配置信息(举例来说，所述WUS配置信息可以包含WUS的时频域信息、WUS的周期、WUS信号特征、WUS最大发送次数、WUS生效区域等WUS配置)发送WUS时，若WUS的同步源发生变更，如从第一WUS同步源变更为第二WUS同步源时，则UE可以相应的变更发送WUS的行为。因此，在一个可能的实现方式中，在所述终端确定所述上行唤醒信号的同步源为第二同步源之后，所述终端通过第二同步源获取发送上行WUS的校准时间，根据获取的所述校准时间进行时间对齐，之后，所述方法还包括以下之一：
(1)所述终端使用与所述第一同步源对应的第一WUS配置信息发送WUS。
可选的，在该可能的实现方式中，第一同步源与第二同步源属于同一全球导航卫星系统(Global Navigation Satellite System，GNSS)系统或同一公共陆地移动网络(Public Land Mobile Network，PLMN)。
在该可能的实现方式中，可选的，所述终端通过第二同步源，获取发送上行唤醒信号的校准时间，包括：所述终端通过所述第二同步源获取所述第一同步源的校准时间。也就是说，UE使用第二同步源获得第一同步源的校时timing。例如，使用第一同步源和第二同步源之间的时间offset(时间差)，则可以通过第二WUS同步源的校时和所述offset，获得UE与第一WUS同步源的校时。所述offset可以由网络侧设备配置给UE，例如，可以包括在所述WUS配置信息中。
在一个可能的实现方式中，如果所述终端通过所述第二同步源获取所述第一同步源校准时间失败，则所述终端停止发送WUS。
(2)所述终端使用与所述第二同步源对应的第二WUS配置信息发送WUS。
在该可能的实现方式中，终端在将WUS的同步源更换为第二同步源之后，使用与第二同步源对应的第二WUS配置信息发送WUS。
在一个可能的实现方式中，如果与所述第二同步源对应的第二WUS配置信息不存在，则终端停止发送WUS。例如，终端检测到第二同步源的同步信号，第二同步源的优先级高于第一同步源的优先级，例如，第二同步源为节能小区，第一同步源也为节能小区，终端确定将上行WUS的同步源更新为第二同步源，但终端在发送WUS时，未获取到第二同步源对应的第二WUS配置信息，例如，网络侧设备发送的WUS配置信息中未指示第二同步源，或者，第二同步源的小区配置信息中未包含WUS配置信息，则终端停止发送 上行WUS。
在本申请实施例的一个可能的实现方式中，该方法还可以包括：在第三情况下，所述终端启动或重启第一计时器，其中，所述第一计时器用于计算在所述第一同步源的有效时间内发送WUS的时长。
可选的，所述第三情况包括但不限于以下至少之一：
(1)确定满足发送WUS的条件；也就是说，在确定满足发送WUS的条件即启动或重启第一计时器。在确定满足发送WUS的条件后，终端认为开始在第一同步源的有效时间内发送WUS，因此，启动或重启第一计时器，计算在第一同步源的有效时间内发送WUS的时长。
(2)发送WUS。也就是说，在终端发送WUS时，启动或重启第一计时器。终端在发送WUS时，认为开始在第一同步源的有效时间内发送WUS，因此，启动或重启第一计时器，计算在第一同步源的有效时间内发送WUS的时长。
可选的，所述UE发送WUS是指UE在一次WUS行为中第一次发送WUS。其中，一次WUS行为可以有多种理解方式。举例来说，一种理解方式为，UE有可用的WUS配置后，判断满足发送WUS条件之后，触发发送WUS，以及后续继续发送WUS或者停止发送WUS的行为。另一种理解方式为，UE有可用的WUS配置后，判断满足发送WUS条件之后，触发发送WUS，后续停止发送WUS。随后，UE重新判断满足发送WUS条件之后，触发发送WUS，以及后续继续发送WUS或者停止发送WUS的行为。
(3)检测到可用的第一同步源的同步信号。即终端在确定上行WUS的同步源为第一同步源之后，在检测到可用的第一同步源发送的同步信号时，即启动或重启第一计时器。终端在检测到可用的第一同步源的同步信号，可以认为第一同步源的有效时间开始，因此，启动或重启第一计时器开始计时。
(4)确定上行WUS的同步源为第二同步源。即终端确定更换同步源时，启动或重启第一计时器。终端在确定更换同步源时，由于更新了同步源，因此，终端启动或重启第一计时器，对终端在第二同步源的有效时间内发送WUS的时长进行计时。
(5)确定与第一同步源失步。即终端在确定与第一同步源失步时，启动或重启第一计时器，判决终端与第一同步源的方法可以参见上述相关的描述，在此不再赘述。终端在确定与第一同步源失步时，由于需要更新了同步源，因此，终端启动或重启第一计时器，对终端在更新后的同步源的有效时间内发送WUS的时长进行计时。
(6)按照所述第二同步源对应的第二WUS配置信息发送WUS。即终端确定更换同 步源后，并按照更换后的第二同步源对应的第二WUS配置信息发送WUS时，启动或重启第一计时器。该实现方式与(4)的区别在于，在更换同步源后，从使用第二同步源对应的第二WUS配置信息发送WUS时才开始计时。
在一个可能的实现方式中，该方法还可以包括：在第四情况下，所述终端停止所述第一计时器。
可选的，所述第四情况包括以下至少之一：
(1)检测到可用的第一同步源的同步信号；也就是说，终端可以在检测到可用的WUS同步源(的同步信号)的情况下，停止第一计时器。终端在检测到可用的第一同步源的同步信号，也可以认为第一同步源的有效时间偿未开始计时，因此，停止第一计时器。
(2)确定上行WUS的同步源为第二同步源，即确定通过第二同步源获取WUS的校准时间，例如，可以根据第二同步源的时间进行时间对齐，或者，通过第二同步源获取第一同步源的校准时间，按照该校准时间与第一同步源进行时间对齐。
(3)接收到重配置消息，其中，所述重配置消息中的WUS配置信息不包括所述第一WUS配置信息。例如，UE收到RRC重配置消息，且所述RRC重配置消息中的WUS配置信息不包含第一WUS配置信息。
(4)读取服务小区的系统消息，且所述系统消息中的WUS配置信息不包括所述第一WUS配置信息。
(5)检测到可驻留小区。
(6)检测到可切换小区。
(7)检测到满足小区重选条件的小区。
(8)检测到小区定义同步信号块(cell-defining SSB，CD-SSB)；CD-SSB定义为与SIB1(也即RMSI)关联的SSB。SIB1定义了其它SIB的调度信息，并包含用于终端初始接入的信息。CD-SSB的频率位置一定在系统同步栅格上，因此，在检测到CD-SSB，终端可以停止第一计时器。
(9)离开所述第一WUS配置信息的生效区域。
(10)发送WUS的次数达到所述第一WUS配置信息所确定的WUS的最大发送次数。
(11)接收到节能小区发送的WUS反馈信息。例如，接收到HARQ ACK/NACK、以标识节能的无线网络临时标识(Radio Network Temporary Identifier，RNTI)或UE的小区RNTI(Cell RNTI，C-RNTI)加扰的物理下行控制信道(Physical downlink control channel，PDCCH)、同步信号和物理广播信道块(synchronization signal and PBCH block，SSB，也 可以称为同步信号块)等。
在一个可能的实现方式中，所述方法还包括：在所述第一计时器超时的情况下，所述终端停止发送WUS。
通过本申请实施例提供的技术方案，通过对上行WUS的同步源失步的定义及上行WUS的同步源的有效时间(及其计时器)的定义，UE在WUS同步源的有效时间内(通过计时器运行的方式)仍然可以发送WUS尝试唤醒节能小区。另外，通过上行WUS的同步源变更的条件及变更后的UE动作的方案，UE可以明确何时需要对WUS的同步源进行变更，以及变更后UE的行为。
图4示出本申请实施例中的唤醒信号的配置方法的一种流程示意图，该方法400可以由网络侧设备执行。换言之，所述方法可以由安装在网络侧设备上的软件或硬件来执行。如图4所示，该方法可以包括以下步骤。
S410，网络侧设备获取终端的第一WUS配置信息，其中，所述第一WUS配置信息用于确定终端发送上行唤醒信号的同步源。
S420，所述网络侧设备向所述终端发送所述第一WUS配置信息。
在一个可能的实现方式中，所述第一WUS配置信息包括但不限于以下至少一项：
(1)同步源信息，用于指示至少一个同步源；

(3)第一时长信息，用于指示各个所述同步源的失步判断时长；
(4)有效时间信息，用于指示各个所述同步源的有效时间；
(5)时间差信息，用于指示所述至少一个同步源中两个同步源之间的校准时间差。
在本申请实施例中的第一WUS配置信息与方法200中的第一WUS配置信息相同，具体可以参见方法200中的描述，在此不再赘述。
