Description

一种通信方法及装置

技术领域
本申请实施例涉及通信领域，尤其涉及一种通信方法及装置。
背景技术
通信系统中，分组数据业务往往是突发的，数据传输偶尔活跃一段时间后会保持更长时间的静默。从延迟的角度来看，终端设备时刻监听物理下行控制信道(physical downlink control channel，PDCCH)，以接收上行调度或下行数据，所产生的时延是最小的。但是，时刻监听PDCCH会导致巨大的功耗。
为了解决时延和功耗的矛盾，新空口(new radio，NR)中引入了非连续接收(discontinuous reception，DRX)、唤醒信号(wake-up signal，WUS)、寻呼预先指示(paging early identification)等机制，用于降低终端设备的功耗。
为了更进一步降低终端设备的功耗，NR开始研究唤醒接收机(wake-up receiver，WUR)。终端设备可以通过WUR进行监听，监听到WUS后可以打开主接收机进行数据收发等。因此，如何实现WUR上的低功耗WUS监听，是目前亟待解决的问题。
发明内容
本申请提供一种通信方法及装置，能够降低终端设备监听唤醒信号WUS的功耗。
第一方面，提供了一种通信方法，该方法可以由第一终端设备执行，也可以由第一终端设备的部件，例如第一终端设备的处理器、芯片、或芯片系统等执行，还可以由能实现全部或部分第一终端设备功能的逻辑模块或软件实现。该方法包括：确定第一资源，并通过第一终端设备的唤醒接收机在第一资源的部分或全部资源上监听唤醒信号，该唤醒信号用于唤醒第一终端设备的主接收机。其中，第一资源包括X个唤醒信号WUS波束，X为小于N的正整数，N为同步信号块SSB波束的数目。
基于该方案，WUS波束的数目小于SSB波束的数目。也就是说，WUS波束的方向小于SSB波束的方向，相比于二者相同的方案，可以减少WUS波束的搜索空间，从而降低终端设备监听WUS的功耗。
在一种可能的设计中，X个WUS波束包括第一WUS波束，第一WUS波束的方向与N个SSB波束中的至少一个SSB波束的方向对应。
基于该可能的设计，由于第一WUS波束的方向与至少一个SSB波束的方向存在对应关系，因此，终端设备可以基于其检测到的SSB波束的方向确定WUS波束的方向。后续可以在其确定的WUS波束方向上监听WUS，无需在所有SSB波束的方向上进行WUS监听，从而可以降低终端设备的功耗。
在一种可能的设计中，该方法还包括：接收来自网络设备的第一信息，第一信息指示第一WUS波束的方向和至少一个SSB波束的方向的对应关系。
在一种可能的设计中，X个WUS波束的方向与N个SSB波束中信号强度最强的前X个SSB波束的方向对应。
基于该可能的设计，由于X个WUS波束的方向与SSB波束中信号强度最强的前X个SSB波束的方向对应，因此，终端设备可以基于信道强度最强的前X个SSB波束的方向确定WUS波束的方向。后续可以在其确定的WUS波束方向上监听WUS，无需在所有SSB波束的方向上进行WUS监听，从而可以降低终端设备的功耗。示例性的，该X个WUS波束的方向可以和信号强度最强的前X个SSB波束的方向相同。
在一种可能的设计中，该方法还包括：确定N个SSB波束各自的信号强度；向网络设备发送第二信息。其中，第二信息指示N个SSB波束各自的信号强度，或者，第二信息指示X个SSB波束的索引。
基于该可能的设计，可以使得网络设备获知第一终端设备对应的WUS波束的方向，从而在需要发送WUS的情况下，在该波束方向上向第一终端设备发送WUS。
在一种可能的设计中，确定第一资源，包括：在第一时间段内测量服务小区的参考信号，得到参考信号的信号质量。在参考信号的信号质量大于第一阈值的情况下，确定第一资源。
基于该可能的设计，该参考信号的信号质量大于第一阈值时，表示终端设备的移动性较低或静止，对 于终端设备来说，对准该终端设备的SSB波束或WUS波束的方向仅发生微小的变化或不会发生变化。该场景下，基于本申请提供的SSB波束和WUS波束的对应关系，能够更准确的根据SSB波束的方向确定WUS波束的方向，或者根据WUS波束的方向确定SSB波束的方向，从而提高接收效率。
在一种可能的设计中，第一终端设备的工作频段属于频率范围2。
第二方面，提供了一种通信方法，该方法可以由第一终端设备执行，也可以由第一终端设备的部件，例如第一终端设备的处理器、芯片、或芯片系统等执行，还可以由能实现全部或部分第一终端设备功能的逻辑模块或软件实现。该方法包括：确定第二资源，通过第一终端设备的唤醒接收机在第二资源上监听唤醒信号，该唤醒信号用于唤醒第一终端设备的主接收机。其中，第二资源包括时域周期资源，时域周期资源位于第一周期内的第一时期，第一周期还包括第二时期，第一时期用于唤醒接收机监听唤醒信号，第二时期用于主接收机收发信号。
基于该方案，一方面，第一周期内的第一时期用于唤醒接收机监听唤醒信号，第二时期用于主接收机收发信号或者用于传统终端，使得网络设备在分配时域资源时能够兼容传统终端，提高适用性。此外，唤醒接收机在第一周期内的部分时间段内监听唤醒信号，相比于唤醒接收机总是打开以监听唤醒信号的方案，可以减少唤醒信号的监听时间，节省终端设备的功耗。另一方面，进一步的，第一时期内的时域周期资源用于唤醒接收机监听唤醒信号，即终端设备可以通过唤醒接收机在第一时期内周期性的监听唤醒信号，在第一时期内的其他时间，唤醒接收机可以休眠，从而进一步节省终端设备的功耗。
在一种可能的设计中，第一终端设备的功耗类型为低功耗时，时域周期资源的周期为第一数值。第一终端设备的功耗类型为极低功耗时，时域周期资源的周期为第二数值，第二数值大于第一数值。
基于该可能的设计，可以为极低功耗类型的终端设备配置较大的WUS监听周期，以减少WUS监听时间，从而进一步降低该终端设备的功耗。
在一种可能的设计中，该方法还包括：向网络设备发送第三信息，第三信息指示第一终端设备的功耗类型，功耗类型包括低功耗或极低功耗。
在一种可能的设计中，该方法还包括：接收来自网络设备的指示信息，指示信息指示以下至少一项：第一周期、第一时期的时长、第二时期的时长、或时域周期资源的周期。
结合第一方面或第二方面，在一种可能的设计中，该方法还包括：接收指示信息，该指示信息可以指示：唤醒信号中不携带信息，或者，唤醒信号中携带以下至少一项：终端设备的标识、系统信息变更指示、系统信息调度信息、(变更后的)系统信息、或偏移信息。其中，偏移信息指示唤醒信号和寻呼时机之间的时间偏移。
结合第一方面或第二方面，在一种可能的设计中，唤醒信号包括第一字段。第一字段的状态为第一状态时，唤醒信号不包括除第一字段之外的字段，或者，唤醒信号还包括偏移信息，偏移信息指示唤醒信号和寻呼时机之间的时间偏移；
第一字段的状态为第二状态时，唤醒信号还包括终端设备的标识；
第一字段的状态为第三状态时，唤醒信号还包括系统信息变更指示或系统信息调度信息；
第一字段的状态为第四状态时，唤醒信号还包括系统信息。
结合第一方面或第二方面，在一种可能的设计中，该方法还包括：第一字段的状态为第一状态时，根据偏移信息唤醒主接收机。
基于该可能的设计，第一字段的状态为第一状态时，主接收机被唤醒，由于主接收机可以采用调制阶数较高的调制方式进行信息调制，因此可以提高寻呼效率。此外，一个PO可以对应多个终端设备，终端设备通过主接收机在PO上进行监听时，网络设备可以在该PO上发送多个终端设备的寻呼信息等，从而提高系统容量。
结合第一方面或第二方面，在一种可能的设计中，该方法还包括：第一字段的状态为第二状态时，在唤醒信号包括第一终端设备的标识的情况下，唤醒主接收机。
基于该可能的设计，终端设备无需频繁唤醒主接收机，只有在确认网络设备对自身发起寻呼时，才唤醒主接收机进行随机接入，可以节省主接收机的功耗。
结合第一方面或第二方面，在一种可能的设计中，该方法还包括：第一字段的状态为第三状态时，获取系统信息变更指示或系统信息调度信息后，唤醒主接收机。
基于该可能的设计，若唤醒信号包括系统信息变更指示，终端设备无需在PO中进行监听即可获知系统信息发生了变更，即可以使得终端设备提前获知系统信息发生变更，在唤醒主接收机后可以直接接收SIB1以接收变更后的系统信息，降低系统信息的接收时延。此外，终端设备无需通过主接收机在PO中进 行监听，也可以节省主接收机的功耗。
若唤醒信号包括系统信息调度信息，终端设备无需在PO中进行监听，并且无需接收SIB1即可获知系统信息调度信息，在唤醒主接收机后可以根据该系统信息调度信息接收变更后的系统信息，降低系统信息的接收时延。此外，终端设备无需通过主接收机在PO中进行监听，也无需通过AIB1获取系统信息调度信息，可以节省主接收机的功耗。
结合第一方面或第二方面，在一种可能的设计中，该方法还包括：第一字段的状态为第四状态时，获取系统信息。
基于该可能的设计，可以极大降低系统信息的接收时延。此外，还可以降低主接收机的唤醒次数和时间，节省终端设备的功耗。
结合第一方面或第二方面，在一种可能的设计中，该方法还包括：第一字段的状态为第四状态时，确定不唤醒主接收机。
第三方面，提供了一种通信方法，该方法可以由网络设备执行，也可以由网络设备的部件，例如网络设备的处理器、芯片、或芯片系统等执行，还可以由能实现全部或部分网络设备功能的逻辑模块或软件实现。该方法包括：确定X个唤醒信号WUS波束的方向与N个同步信号块SSB波束的方向的对应关系，X为小于N的正整数；向第一终端设备发送指示信息，该指示信息指示X个WUS波束的方向与N个SSB波束的方向的对应关系。
基于该方案，一方面，WUS波束的数目小于SSB波束的数目，可以减少WUS波束的搜索空间，从而降低终端设备监听WUS的功耗。另一方面，由于对于一个终端设备，WUS波束的数量相较于SSB波束的数量较小，使得网络设备可以在其他SSB波束方向上向其他终端设备发送信号，从而提升系统容量。再一方面，对于一个终端设备，WUS波束的数量较小，相当于WUS重复发送的次数较小，相比于通过N个WUS波束发送N次WUS，占用的资源减少，从而本申请的方案也可以提高WUS的数据传输速率。
在一种可能的设计中，X个WUS波束包括第一WUS波束，第一WUS波束的方向与N个SSB波束中的至少一个SSB波束的方向对应。
在一种可能的设计中，该指示信息包括第一WUS波束的方向与N个SSB波束中的至少一个SSB波束的方向的对应关系。

其中，上述适用本申请的通信系统仅是举例说明，适用本申请的通信系统不限于此，在此统一说明，以下不再赘述。
如图1所示，为本申请提供的一种可能的通信系统的结构示意图。图1中以该通信系统包括至少一个网络设备110，以及与该网络设备110连接的一个或多个终端设备120为例进行说明。应理解，图1中的终端设备和网络设备的数量仅是举例，还可以更多或者更少。

可选的，AAU可以实现部分物理层处理功能、射频处理及有源天线的相关功能。RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来。因此在该架构下，高层信令(如RRC层信令)也可以认为是由DU发送的，或者，由DU和AAU发送的。
进一步的，如图2b所示，还可以将CU的控制面(CU control plane，CU-CP)和用户面(CU user plane，CU-UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。

可选的，WUR和主接收机之间可以相互通信。终端设备可以通过WUR监听唤醒信号(wake-up signal，WUS)，监听到WUS后可以打开主接收机进行信号收发。主接收机的功耗高于WUR的功耗。
可选的，WUR和主接收机可以是终端设备的两个功能模块，或者，可以是终端设备的两个实体。在硬 件实现上，WUR和主接收机可以共享一套硬件资源，或者，可以共享部分硬件资源，或者，可以由两套独立的硬件资源实现，本申请对此不作具体限定。
本申请实施例中，WUR也可以称为WUR链路，主接收机也可以称为主链路。具备WUR和主接收机的终端设备可以称为双连接终端或双连接终端设备。当然，也可以有其他名称，本申请对此不作具体限定。
下面将结合附图，对本申请实施例提供的方法进行展开说明。可以理解的，本申请实施例中，网络设备或终端设备可以执行本申请实施例中的部分或全部步骤，这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。
示例性的，本申请下述实施例提供的方法可以应用于WUS监听的场景。当然，此处仅是示例性的对本申请的应用场景进行说明，该应用场景对本申请不造成任何限定，本申请对下述提供的方法的应用场景也不作具体限定，例如还可以用于其他信号的监听，或者其他涉及信号的场景。
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
1、同步信号块(synchronization signal block，SSB)：
主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)、和物理广播信道(physical broadcast channel，PBCH)可以合称为SSB。
在NR系统中，网络设备可以通过波束扫描的方式发送SSB，即以时分复用的方式在不同波束上发送多个SSB。示例性的，如图3所示，网络设备可以在不同波束上发送SSB 0至SSB N。通过波束扫描发送的多个SSB可以称为同步信号(synchronization signal，SS)突发集(SS burst set)。例如，图3中的SSB0至SSB N可以称为一个同步信号突发集。
波束可以理解为一种通信资源。形成波束的技术可以是波束赋形技术或者其他技术手段。不同的波束可以认为是不同的资源。
波束在协议中具体地可以通过各种信号(或资源)的索引来表示，例如通过信道状态信息参考信号(channel state information reference signal，CSI-RS)的资源索引、SSB索引，探测参考信号(sounding reference signal，SRS)的资源索引，跟踪参考信号(tracking reference signal，TRS)的资源索引等表示。
此外，波束在协议中的体现还可以是空域滤波器(spatial domain filter)，或者称空间滤波器(spatial filter)，或称空域参数(spatial domain parameter)，空间参数(spatial parameter)，空域设置(spatial domain setting)，空间设置(spatial setting)，或准共址(quasi Co-location，QCL)信息，QCL假设，QCL指示等。波束可以通过传输配置指示(transmission configuration indication，TCI)状态(TCI-state)参数来指示，或通过空间关系(spatial relation)参数来指示。因此，本申请中，波束也可以替换为空域滤波器，空间滤波器，空域参数，空间参数，空域设置，空间设置，QCL信息，QCL假设，QCL指示，TCI-state，或空间关系等。上述术语之间也相互等效。本申请中的波束也可以替换为其他表示波束的术语，本申请不作限定。
本申请中，将用于发送SSB的波束称为SSB波束。SSB波束可以通过SSB索引、QCL信息，QCL假设，QCL指示，TCI-state，或空间关系等来表示。
2、寻呼(paging)：
在移动通信网络中，网络对终端设备的寻呼通常分为两类，一类用于通过寻呼(Paging)消息通知处于无线资源控制(radio resource control，RRC)空闲态或RRC非激活态的终端设备进行随机接入，从而使得该终端设备进入RRC连接态，以便后续进行数据通信；另一类用于通过短消息通知终端设备接收系统信息。
示例性的，系统信息可以包括承载在系统信息块(system information block，SIB)6、SIB7、或SIB8上的公共安全告警信息，或者包括承载在除SIB6、SIB7和SIB8之外的其他SIB上的信息。公共安全告警信息例如可以包括地震海啸告警系统(earthquake and tsunami warning system，ETWS)信息、商业移动警示服务(commercial mobile alert service，CMAS)信息等。
终端设备可以在寻呼时机(paging occasion，PO)中接收由寻呼无线网络临时标识(paging radio network temporary identifier，P-RNTI)加扰的物理下行控制信道(physical downlink control channel，PDCCH)，根据该PDCCH中的寻呼下行控制信息(downlink control information，DCI)接收系统信息或物理下行共享信道(physical downlink share channel，PDSCH)中的寻呼消息。
寻呼DCI中可以包括2比特(bit)的短消息指示字段，该短消息字段的定义可以如表1所示。
表1

在寻呼DCI中携带短消息的情况下，该短消息可以通过8比特的短消息字段承载。该短消息指示字段的定义可以如表2所示。
表2
其中，BCCH表示广播控制信道(broadcast control channel，BCCH)。DRX指非连续接收(discontinuous reception，DRX)。
在短消息指示系统信息发生更新时，终端设备可以从SIB1中获取系统信息调度信息(SI scheduling information，SI-SchedulingInfo)，再根据系统信息调度信息中的配置，接收用于调度系统信息的DCI，之后根据该DCI接收更新后的系统信息。
3、寻呼早期指示(paging early identification，PEI)：
PEI用于指示其对应的PO中是否存在寻呼消息。在一个或多个PO之前，网络设备可以向终端设备发送PEI，用于告知终端设备该一个或多个PO中是否包括该终端设备的寻呼消息。如果PEI指示一个或多个PO中不包括该终端设备的寻呼消息，终端设备可以跳过该一个或多个PO的监听，并进入睡眠状态以达到节能的目的。如果PEI指示还指示一个或多个PO中包括该终端设备的寻呼消息，终端设备需要监听该一个或多个PO。
示例性的，如图4所示，假设PEI监听时机1对应PO1、PO2、PO3、和PO4。若PEI监听时机1中监听到的PEI指示该4个PO中不包括终端设备的寻呼消息，那么终端设备将进入睡眠状态，不在该4个PO中进行监听。若PEI监听时机1中监听到的PEI指示该4个PO中包括终端设备的寻呼消息，终端设不需要在该4个PO中进行监听。
目前，网络设备采用与SSB准共址的方式发送PEI。即，若网络设备在N个波束方向上发送SSB，那么也在相同的N个波束方向上发送PEI。
对于NR版本18提出的WUR，若要实现WUR的监听功耗低于主接收机睡眠状态的功耗，WUR需要采用开关键控(on-off keying，OOK)、频移键控(frequency-shift keying，FSK)等支持低功耗接收的调制方式。然而，OOK等调制方式的数据速率较低，因此，对于同样大小的信息，相比于QPSK等高阶调制方式，采用OOK等调制方式发送时需要更长的时间，即需要终端设备花费更长的时间接收。该场景下，若参考PEI技术，采用与SSB准共址的方式发送WUS，需要终端设备在较多方向花费更长的时间进行监听，从而导致终端设备的监听功耗较高。
基于此，本申请提供一种通信方法，通过对WUS的传输资源的设计，可以减少终端设备监听WUS的时间，从而实现终端设备节能。
如图5所示，为本申请提供的一种通信方法，该方法包括：
S501、第一终端设备确定第一资源。
其中，该第一资源包括X个WUS波束。X为小于N的正整数，N为SSB波束的数目，N为正整数。也就是说，本申请实施例中，WUS波束的数目小于SSB波束的数目。示例性的，WUS波束可以理解为用于发送WUS的波束。WUS波束可以使用WUS的索引表示。
可选的，SSB波束的数目和网络设备实际发送的SSB的数目相同。示例性的，该数目N可以根据SIB1中的参数ssb-PositionInBurst确定。
可选的，WUS波束的数目X可以是网络设备向第一终端设备通知的，例如，网络设备可以通过RRC信令或DCI向第一终端设备指示该数目X。或者，WUS波束的数目X可以是协议定义的。或者，WUS波束的数目X可以是第一终端设备自主确定的，该场景下，第一终端设备还可以向网络设备上报该WUS波束的数目X。本申请对此不做具体限定。
可选的，该X个WUS波束和该N个SSB波束之间可以存在如下两种对应情况：
情况一、一个WUS波束的方向与M个SSB波束的方向对应，M为正整数。M大于1时，即一个WUS波束的方向与多个SSB波束的方向对应。
也就是说，假设X个WUS波束中包括第一WUS波束，该第一WUS波束的方向与N个SSB波束中的至少一个SSB波束的方向对应。该第一WUS波束可以是X个WUS波束中的任意一个WUS波束。
可选的，一个WUS波束的方向与M个SSB波束的方向对应，可以理解为：该WUS波束的方向可以根据该M个SSB波束的方向确定，或者说，该WUS波束的方向是该M个SSB波束的方向的函数。示例性的，WUS波束的方向角可以通过M个SSB波束的方向角线性表示。例如，WUS波束的方向角等于M个SSB波束的方向角的平均值。以WUS波束的方向角为θ0，M个SSB波束的方向角分别为θ1,θ2,…θM为例，当M＝2，θ1＝0°，θ2＝90°时，θ0＝(θ1+θ2)/2＝45°。获知WUS波束的方向角后，可以根据该方向角确定WUS波束对应的天线中相邻单元连接的移相器的相位差其中，相位差和波束的方向角之间的关系为λ为波长，d为相邻单元之间的距离。
可选的，波束的方向具体可以由接收参数、空域参数、空间参数、空域设置、空间设置等参数表示，本申请对此不做具体限定。
需要说明的是，本申请中，WUS波束的方向与SSB波束的方向对应，也可以描述为：WUS波束与SSB波束对应。二者可以相互替换，本申请对此不做具体限定。
作为一种可能的实现，该X个WUS波束中不同的WUS波束的方向对应的SSB波束的方向不重叠。
示例性的，以SSB波束的数目N等于4，WUS波束的数目X等于2为例，如图6所示，SSB1和SSB2的波束方向可以对应WUS1的波束方向，SSB3和SSB4的波束方向可以对应WUS2的波束方向。图6中，每个部分的椭圆形数目表示波束的总数，使用黑色填充的椭圆形表示某个SSB波束或WUS波束的方向。例如图6中所示，SSB1的波束方向为0°，SSB2的波束方向为90°等。
需要说明的是，图6仅是对N等于4，X等于2时，SSB波束和WUS波束的对应关系的一种示例性说明。此外，该4个SSB波束和2个WUS波束的对应关系还可以如表3所示。
表3
其中，对应关系1表示SSB1和SSB3的波束方向对应WUS1的波束方向，SSB2和SSB4的波束方向对应WUS2的波束方向。对应关系2表示SSB1和SSB4的波束方向对应WUS1的波束方向，SSB2和SSB3的波束方向对应WUS2的波束方向。
作为另一种可能的实现，该X个WUS波束中不同的WUS波束的方向对应的SSB波束的方向存在重叠。
示例性的，以SSB波束的数目N等于4，WUS波束的数目X等于2为例，该4个SSB波束的方向和2个WUS波束的方向的对应关系可以包括但不限于：SSB1、SSB2、和SSB3的波束方向对应WUS1的波束方向，SSB2、SSB3、和SSB4的波束方向对应WUS2的波束方向。
需要说明的是，N等于4，X等于2仅是本申请对N和X取值的一种示例性说明，N和X还可以有其他取值。例如，N等于16，X等于2；或者，N等于16，X等于1；或者，N等于8，X等于2；或者，N等于8，X等于1；或者，N等于4，X等于1等，本申请对N和X的取值不做具体限定。
可选的，该可能的实现中，X个WUS波束的方向与N个SSB波束的方向之间的对应关系可以是协议定义的。或者，可以是网络设备向第一终端设备指示的。该场景下，如图7所示，该步骤S501之前还可 以包括：
S500a、网络设备确定X个WUS波束的方向与N个SSB波束的方向的对应关系。
S500b、网络设备向第一终端设备发送指示信息。相应的，第一终端设备接收来自网络设备的指示信息。
其中，该指示信息指示X个WUS波束的方向与N个SSB波束的方向的对应关系。
在一个WUS波束的方向与M个SSB波束的方向对应的情况下，假设X个WUS波束包括第一WUS波束，该指示信息中可以包括第一信息，该第一信息可以指示第一WUS波束的方向和M个SSB波束的方向的对应关系。
示例性的，该指示信息可以以列表的形式实现，例如，指示信息可以包括类似于上述表3的表格来指示每个WUS波束的方向对应的M个SSB波束的方向。或者，该指示信息可以以键值对的形式实现，例如，指示信息可以包括：{SSB1，SSB2：WUS1}、{SSB3，SSB4：WUS2}，以指示上述图6所示的对应关系。当然，该指示信息还可以通过其他形式实现，本申请对此不做具体限定。
可选的，该场景下，上述步骤S501具体可以为：第一终端设备根据指示信息确定X个WUS波束。示例性的，网络设备可以在系统信息中向第一终端设备发送N个SSB的相关配置，从而第一终端设备可以获知N个SSB波束的索引、方向等信息。收到指示信息后，结合N个SSB的相关信息，第一终端设备即可以根据指示信息获知X个WUS波束的信息。
此外，该场景下，网络设备可以根据SSB波束的方向和上述对应关系确定X个WUS波束的方向，后续在需要向第一终端设备发送WUS时，可以在该X个WUS波束上向第一终端设备发送WUS。
情况二、X个WUS波束的方向与N个SSB波束中信号强度最强的前X个SSB波束的方向对应。即X个WUS波束的方向与该X个SSB波束的方向一一对应。
可选的，该情况二中，WUS波束的方向与SSB波束的方向对应，可以理解为：WUS波束的方向与该SSB波束的方向相同。或者，WUS波束的方向与该SSB波束的方向之间的差值小于某个阈值。
示例性的，以SSB波束的数目N等于4，WUS波束的数目X等于2为例，如图8所示，假设4个SSB波束中，信号强度最强的两个SSB波束为SSB1的波束和SSB2的波束，那么，WUS1的波束方向和SSB1的波束方向对应(例如相同)，WUS2的波束方向和SSB2的波束方向对应(例如相同)。
可选的，该可能的实现中，X个WUS波束的方向与N个SSB波束的方向之间的对应关系可以是协议定义的。或者，可以是网络设备向第一终端设备指示的。该场景下，如图7所示，该步骤S501之前还可以包括：
S500a、网络设备确定X个WUS波束的方向与N个SSB波束的方向的对应关系。
S500b、网络设备向第一终端设备发送指示信息。相应的，第一终端设备接收来自网络设备的指示信息。
其中，该步骤S500a和步骤S500b的实现与情况一中的步骤S500a和步骤S500b的实现类似，区别在于：在情况二中，指示信息可以包括WUS波束的数目X。第一终端设备收到该指示信息后，即可获知X个WUS波束的方向与N个SSB波束中信号强度最强的前X个SSB波束的方向对应。
可选的，在步骤S501之前，第一终端设备可以对N个SSB波束进行测量，确定该N个SSB波束各自的信号强度，并按照信号强度由大到小的顺序对该N个SSB波束的信号强度排序，得到排名前X的SSB波束，该X个SSB波束即为信号强度最强的前X个SSB。
可选的，SSB波束的信号强度可以通过参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)等参数表示，本申请对此不做具体限定。
可选的，第一终端设备还可以向网络设备发送第二信息。相应的，网络设备接收来自第一终端设备的第二信息。其中，该第二信息指示N个SSB波束各自的信号强度，或者，指示信号强度最强的前X个SSB波束的索引。SSB波束的索引可以理解为SSB的索引，二者可以相互替换。
可选的，网络设备可以向第一终端设备配置上报类型，该上报类型可以为信号强度，此时，第二信息可以指示N个SSB波束各自的信号强度。或者，该上报类型可以为SSB波束的索引，此时，第二信息可以指示该X个SSB波束的索引。
可选的，网络设备收到第二信息后，可以根据第二信息确定X个WUS波束的方向。后续需要向第一终端设备发送WUS时，网络设备可以在该X个WUS波束上向第一终端设备发送WUS。
S502、第一终端设备通过唤醒接收机在第一资源的部分或全部资源上监听唤醒信号。该唤醒信号用于唤醒第一终端设备的主接收机。
可选的，在X个WUS波束和N个SSB波束之间的对应情况为上述情况一时，第一终端设备可以确定信号质量大于或等于第二阈值的SSB波束对应的WUS波束，从而通过唤醒接收机在在该WUS波束上监听唤醒信号。即第一终端设备通过唤醒接收机在第一资源的部分资源上监听唤醒信号。
示例性的，基于图6所示的示例，若信号质量大于或等于第二阈值的SSB波束为SSB1的波束和SSB2的波束，那么第一终端设备可以在WUS1的波束上监听WUS，不在WUS2的波束上监听WUS。
可选的，第二阈值可以是协议预定义的；或者，可以是网络设备配置的；或者，可以是第一终端设备自行确定的，本申请对此不做具体限定。此外，本申请实施例还涉及第一阈值，将在后续实施例中说明，在此不予赘述。
可选的，在X个WUS波束和N个SSB波束之间的对应情况为上述情况一时，第一终端设备也可以通过唤醒接收机在第一资源的全部资源上监听唤醒信号，本申请对此不做具体限定。
可选的，在X个WUS波束和N个SSB波束之间的对应情况为上述情况二时，第一终端设备可以通过唤醒接收机在第一资源的全部资源上监听唤醒信号。
可选的，若第一终端设备通过唤醒接收机监听到WUS，则第一终端设备可以唤醒主接收机。后续可以根据网络设备的调度通过主接收机收发信号。
基于该方案，一方面，WUS波束的数目小于SSB波束的数目，也就是说，WUS波束的方向小于SSB波束的方向，相比于二者相同的方案，可以减少WUS波束的搜索空间，从而降低终端设备监听和接收WUS的功耗。
另一方面，基于X个WUS波束和N个SSB波束的对应关系，终端设备可以基于其搜索到的WUS波束确定SSB波束的方向，相比于终端设备在全部SSB波束方向上搜索SSB波束，可以减少SSB波束的搜索和接收功耗，由于SSB需要通过主接收机监听和接收，因此，可以降低主接收机的功耗。
示例性的，基于图6所示的对应关系，假设终端设备在WUS1的波束方向上监听到WUS，或者WUS1的波束方向上WUS的信号质量大于某个阈值，后续，终端设备即可在WUS1对应的SSB1和SSB2的波束方向上监听和接收SSB，在SSB3和SSB4的波束方向上不进行SSB的监听和接收。
再一方面，由于对于一个终端设备，WUS波束的数量相较于SSB波束的数量较小，使得网络设备可以在其他SSB波束方向上向其他终端设备发送信号，从而提升系统容量。此外，对于一个终端设备，WUS波束的数量较小，相当于WUS重复发送的次数较小，相比于通过N个WUS波束发送N次WUS，占用的资源减少，从而本申请的方案也可以提高WUS的数据传输速率。
可选的，图5所示的方法可以应用于终端设备的移动性较低或终端设备静止的场景。示例性的，终端设备在一段时间内测量得到的服务小区的参考信号的信号质量大于或等于门限值1时，可以认为终端设备的移动性较低。该段时间内测量得到的服务小区的参考信号的信号质量大于或等于门限值2时，可以认为终端设备静止。示例性的，该段时间内的服务小区的参考信号的信号质量可以是该段时间内的参考信号的平均信号质量。
其中，门限值2大于门限值1。该门限值1和门限值2可以是协议定义的；或者，可以是网络设备配置的，本申请对此不作具体限定。
可选的，终端设备或网络设备可以在确定终端设备的移动性较低或静止的场景下，执行上述图5所示的方法。也就是说，上述步骤S501具体可以为：终端设备在第一时间段内测量服务小区的参考信号，得到该参考信号的信号质量；在该参考信号的信号质量大于第一阈值的情况下，确定第一资源。其中，第一阈值可以为上述门限值1或门限值2。
可选的，终端设备得到第一时间段内参考信号的信号质量后，可以向网络设备发送该参考信号的信号质量；或者，可以向网络设备指示该参考信号的信号质量是否大于第一阈值。网络设备可以根据终端设备的上报，确定是否执行图5所示的方法。
可选的，参考信号的信号质量可以通过RSRP、RSRQ等表示，本申请对此不作具体限定。
基于该方案，终端设备的移动性较低或静止的情况下，对于终端设备来说，对准该终端设备的SSB波束或WUS波束的方向仅发生微小的变化或不会发生变化。该场景下，基于本申请提供的SSB波束和WUS波束的对应关系，能够更准确的根据SSB波束的方向确定WUS波束的方向，或者根据WUS波束的方向确定SSB波束的方向，从而提高接收效率。
可选的，第一终端设备的工作频段可以属于频率范围2。此外，第一终端设备可以通过模拟域波束接收的方式工作。基于该方式，第一终端设备无需执行复杂的模数转换过程，通过简单的移相器即可调整接收波束方向，以接收WUS波束，从而可以实现低功耗接收。
上述图5所示的方法可以理解为对WUS空域资源的设计。此外，本申请还提供一种通信方法对WUS时域资源进行设计。如图9所示，该方法包括如下步骤：
S901、第一终端设备确定第二资源。
其中，该第二资源包括时域周期资源。该时域周期资源位于第一周期内的第一时期。第一周期还包括第二周期。该第一时期可以用于唤醒接收机监听唤醒信号。第二时期用于主接收机收发信号。
换句话说，本申请中可以将第一周期内的时域资源分为两部分，其中一部分可以分配给唤醒接收机，用于唤醒接收机监听唤醒信号。另一部分可以分配给主接收机，用于主接收机收发信号。此外，该另一部分时域资源还可以分配不支持唤醒接收机的传统(legacy)终端设备。
可选的，该第一周期可以称为外层DRX周期或第一DRX周期。第一周期内的第一时期可以称为激活时期或活动态时期。第一周期内的第二时期可以称为非激活时期或睡眠时期或非活动态时期。当然，第一周期、第一时期、和第二时期也可以有其他名称，本申请对此不做具体限定。
示例性的，如图10所示，第一周期包括第一时期和第二时期，第一时期内包括时域周期资源。终端设备可以在该时域周期资源上监听唤醒信号。
可选的，该时域周期资源可以理解为内层DRX机制。即，第一终端设备可以通过唤醒接收机在该时域周期资源内监听唤醒信号。在第一时期内除该周期资源外的其他时期，第一终端设备的唤醒接收机可以休眠，从而节省唤醒接收机的功耗。示例性的，该时域周期资源的周期可以称为内层DRX周期或第二DRX周期。
可选的，该时域周期资源的周期可以为第二周期。第二周期的取值可以根据第一终端设备的功耗类型确定。示例性的，第一终端设备的功耗类型为低功耗时，第二周期的取值可以为第一数值；第一终端设备的功耗类型为极低功耗时，第二周期的取值可以为第二数值。其中，第二数值大于第一数值。
也就是说，相比于低功耗类型的终端设备，可以为极低功耗类型的终端设备配置较大的监听周期，减少终端设备的监听时间，从而节省终端设备的功耗。
可选的，终端设备的功耗类型(包括低功耗或极低功耗)可以是终端设备出厂时的默认配置，终端设备通过读取该默认配置，即可获知自身的功耗类型。或者，终端设备的功耗类型可以根据用户的设置确定。例如，用户开启终端设备的省电模式时，该终端设备的功耗类型为极低功耗；用户关闭终端设备的省电模式时，例如用户设置终端设备处于性能模式，该终端设备的功耗类型可以为低功耗。或者，终端设备的功耗类型可以根据终端设备的剩余电量确定。例如，剩余电量小于或等于20％时，终端设备的功耗类型可以为极低功耗；剩余电量大于20％时，终端设备的功耗类型可以为低功耗。
可选的，第二资源可以是网络设备向第一终端设备配置的。该场景下，在步骤S901之前，本申请提供的方法还可以包括如下步骤：
S900a、网络设备确定第二资源。
可选的，网络设备确定第二资源可以包括，网络设备确定以下至少一项：第一周期、第一时期的时长、第二时期的时长、或第二周期。
可选的，第二周期可以是网络设备根据第一终端设备的功耗类型确定的。该场景下，第一终端设备可以向网络设备发送第三信息。相应的，网络设备接收来自第一终端设备的第三信息。其中，该第三信息可以指示第一终端设备的功耗类型。网络设备收到第三信息后，可以根据第三信息确定第二周期。例如，在终端设备的类型为低功耗时，确定第二周期的取值为第一数值；在终端设备的类型为极低功耗时，确定第二周期的取值为第二数值。
可选的，该第三信息可以是随机接入过程中上报的，例如，第一终端设备可以在随机接入中的消息1(Msg1)、消息3(Msg3)、或消息A(MsgA)中上报的。
或者，该第三信息可以携带在辅助信息中。网络设备可以通过RRC重配信令下发辅助信息配置。第一终端设备接收到该信令后按照对应的配置上报辅助信息。相较于一次性静态的终端设备能力上报，辅助信息的上报可以动态变化。例如，网络设备可以配置第一终端设备周期性上报辅助信息，或者在第一终端设备的功耗类型发生变化时上报辅助信息。
或者，第三信息可以是第一终端设备的功耗类型发生变化后，第一终端设备上报的。例如，用户开启终端设备的省电模式时，该终端设备的功耗类型由低功耗变为极低功耗，那么第一终端设备可以向网络设备上报该第三信息。
S900b、网络设备向第一终端设备发送指示信息。相应的，第一终端设备接收来自网络设备的指示信息。
其中，该指示信息指示第二资源。示例性的，指示信息可以指示以下至少一项：第一周期、第一时期的时长、第二时期的时长、或第二周期。
可选的，网络设备可以在第一终端设备的主接收机对应的资源(或链路)上发送该指示信息。该场景下，指示信息可以携带在随机接入中的消息2(Msg2)、消息4(Msg4)、或消息B(MsgB)中；或者，指示信息可以携带在PDCCH上的DCI中。
网络设备也可以在第一终端设备的唤醒接收机对应的资源(或链路)上发送该指示信息。该场景下，指示信息可以携带在WUS中。第一终端设备收到该指示信息后，可以根据WUS中携带的该指示信息调整WUS的监听时间等。
可选的，该场景下，上述步骤S901具体可以为：第一终端设备根据指示信息确定第二资源。
S902、第一终端设备通过唤醒接收机在第二资源上监听唤醒信号。该唤醒信号用于唤醒第一终端设备的主接收机。
即，第一终端设备可以通过唤醒接收机在第一时期内的时域周期资源上周期性监听唤醒信号。在第一时期内的其他时间，唤醒接收机可以休眠。此外，在第二时期，唤醒接收机也可以休眠。
可选的，若第一终端设备通过唤醒接收机监听到WUS，则第一终端设备可以唤醒主接收机。后续可以根据网络设备的调度通过主接收机收发信号。
基于该方案，一方面，第一周期内的第一时期用于唤醒接收机监听唤醒信号，第二时期用于主接收机收发信号或者用于传统终端，使得网络设备在分配时域资源时能够兼容传统终端，提高适用性。此外，唤醒接收机在第一周期内的部分时间段内监听唤醒信号，相比于唤醒接收机总是打开(always on)以监听唤醒信号的方案，可以减少唤醒信号的监听时间，节省终端设备的功耗。
另一方面，进一步的，第一时期内的时域周期资源用于唤醒接收机监听唤醒信号，即终端设备可以通过唤醒接收机在第一时期内周期性的监听唤醒信号，在第一时期内的其他时间，唤醒接收机可以休眠，从而进一步节省终端设备的功耗。
需要说明的是，上述图5和图9所示的方法可以独立使用，即二者之间不存在依赖关系。或者，可以结合使用，例如，WUS的空域资源可以为上述图5所示方法中的第一资源，WUS的时域资源可以为上述图9所示方法中的第二资源。
以上，对唤醒信号的空域资源和时域资源进行了说明。下面，将对本申请提供的唤醒信号中携带的内容，或者说，唤醒信号的组成(或帧结构)进行说明。
可选的，唤醒信号可以包括以下至少一项：指示信息、终端设备的标识、系统信息变更指示、系统信息调度信息、(变更后的)系统信息、或偏移信息。
可选的，该指示信息可以指示唤醒信号携带的内容，或者说，指示唤醒信号的组成(或帧结构)。系统信息变更指示可以指示除SIB6、SIB7、SIB8外的BCCH中的系统信息发生更新。系统信息调度信息用于调度DCI，该DCI用于调度系统信息。
可选的，偏移信息指示唤醒信号和PO之间的时间偏移(offset)。当唤醒信号中包括偏移信息时，终端设备可以在收到唤醒信号后延迟唤醒主接收机，延迟的时长即为该偏移信息指示的时间偏移。
可选的，该偏移信息可以包括两级偏移，例如，包括无线帧级别的偏移和时隙级别的偏移。该场景下，指示信息指示的时间偏移长度即为无线帧级别的偏移时长加上时隙级别的偏移时长。基于该两级偏移，可以使得唤醒主接收机的时间偏移的精度较为宽松，更适用于唤醒接收机的时钟精度。
可选的，在唤醒信号中包括指示信息的情况下，上述指示信息可以通过唤醒信号中的第一字段承载(即唤醒信号包括第一字段)，第一字段的不同状态可以理解为指示信息的不同指示。
可选的，第一字段的状态为第一状态时，唤醒信号不包括除第一字段之外的字段。换句话说，唤醒信号仅包括第一字段，或者说，唤醒信号仅包括第一字段承载的指示信息。或者，第一字段的状态为第一状态时，唤醒信号还包括上述偏移信息。
第一字段的状态为第二状态时，唤醒信号还包括终端设备的标识。
第一字段的状态为第三状态时，唤醒信号还包括系统信息变更指示或系统信息调度信息。
第一字段的状态为第四状态时，唤醒信号还包括系统信息。示例性的，该系统信息可以为更新后的系统信息，例如，公共安全告警信息，或除SIB6、SIB7、SIB8外的其他SIB中承载的系统信息发生变更后的信息。
即，第一字段的不同状态及其指示的唤醒信号携带的内容，或唤醒信号的组成(或帧结构)，可以如表4所示。
表4
可选的，上述第一字段的状态可以通过第一字段的取值表示。第一字段的大小(size)可以为2比特。此时，示例性的，第一字段的取值为“00”时可以表示第一字段的第一状态；取值“01”可以表示第一字段的第二状态；取值“10”可以表示第一字段的第三状态；取值“11”可以表示第一字段的第四状态。当然，取值“00”也可以表示其他状态，例如第二状态或第三状态或第四状态等，本申请对此不作具体限定。
需要说明的是，本申请并不限定第一字段一定存在上述四种状态，例如，第一字段的状态可以仅包括上述四种状态中的至少一个。此时，第一字段的大小也不一定是2比特。例如，第一字段的上述第一状态和第二状态存在，第三状态和第四状态不存在，第一字段的大小可以为1比特。
上述以第一字段的不同状态表示指示信息的不同指示(即通过比特状态实现指示信息)，为例进行说明。此外，该指示信息也可以通过其他显式方式实现，本申请对此不作具体限定。
可选的，第一终端设备还可以第一字段的不同状态执行不同的操作。示例性的：
第一字段的状态为第一状态时，若唤醒信号不包括除第一字段之外的字段，第一终端设备在监听到唤醒信号后，可以立即唤醒主接收机，并通过主接收机在PO上进行监听。若唤醒信号还包括偏移信息，第一终端设备可以根据偏移信息唤醒主接收机，并通过主接收在PO上进行监听。例如，第一终端设备可以在收到唤醒信号后延迟唤醒主接收机，延迟的时长即为该偏移信息指示的时间偏移。
可选的，网络设备可以在广播寻呼场景下，在唤醒信号中不携带第一字段外的字段，或携带偏移信息，使得终端设备唤醒主接收机，并通过主接收机在PO上进行监听。由于主接收机可以采用调制阶数较高的调制方式进行信息调制，因此可以提高寻呼效率。此外，一个PO可以对应多个终端设备，终端设备通过主接收机在PO上进行监听时，网络设备可以在该PO上发送多个终端设备的寻呼信息等，从而提高系统容量。
第一字段的状态为第二状态时，在唤醒信号包括第一终端设备的标识的情况下，第一终端设唤醒其主接收机。
可选的，第一终端设备可以获取唤醒信号中携带的终端设备的标识，在该标识为第一终端设备的标识时，表示网络对该第一终端设备发起了寻呼。该场景下，第一终端设备可以唤醒主接收机。后续，第一终端设备可以通过主接收机在随机接入信道(random access channel，RACH)上进行随机接入(random access，RA)，以响应网络的寻呼。
基于该处理，终端设备无需频繁唤醒主接收机，只有在确认网络设备对自身发起寻呼时，才唤醒主接收机进行随机接入，可以节省主接收机的功耗。
第一字段的状态为第三状态时，第一终端设备获取系统信息变更指示或系统信息调度信息后，唤醒主接收机。
可选的，若唤醒信号包括系统信息变更指示，第一终端设备监听到唤醒信号并获取该系统信息变更指示后，可以唤醒主接收机。后续，第一终端设备可以通过主接收机接收SIB1，获取SIB1中的系统信息调度信息，再根据系统信息调度信息接收变更后的系统信息。
基于该处理，终端设备无需在PO中进行监听即可获知系统信息发生了变更，即可以使得终端设备提前获知系统信息发生变更，在唤醒主接收机后可以直接接收SIB1以接收变更后的系统信息，降低系统信息的接收时延。此外，终端设备无需通过主接收机在PO中进行监听，也可以节省主接收机的功耗。
若唤醒信号包括系统信息调度信息，第一终端设备监听到唤醒信号并获取该系统信息调度信息后，可以唤醒主接收机。后续，第一终端设备可以根据该系统信息调度信息接收变更后的系统信息。
基于该处理，终端设备无需在PO中进行监听，并且无需接收SIB1即可获知系统信息调度信息，在唤醒主接收机后可以根据该系统信息调度信息接收变更后的系统信息，降低系统信息的接收时延。此外，终端设备无需通过主接收机在PO中进行监听，也无需通过AIB1获取系统信息调度信息，可以节省主接收机的功耗。
第一字段的状态为第四状态时，第一终端设备可以获取系统信息。该系统信息可以理解为变更后的系统信息。
示例性的，该系统信息为公共安全告警信息，例如地震、海啸等告警信息时，第一终端设备可以通过短信、震动、响铃等方式向用户发起预警。
可选的，若唤醒信号包括系统信息，第一终端设备监听到唤醒信号并获取该系统信息后，可以确定不唤醒主接收机，即，即使第一终端设备监听到唤醒信号，在该唤醒信号包括系统信息的情况下，第一终端设备可以不唤醒主接收机。
基于该处理，可以极大降低系统信息的接收时延。此外，还可以降低主接收机的唤醒次数和时间，节省终端设备的功耗。
