Description

一种辅助小区激活的方法和通信装置
本申请要求于2018年12月29日提交中国专利局、申请号为201811647479.2、申请名称为“一种辅助小区激活的方法和通信装置”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，并且更具体地，涉及一种辅助小区激活的方法和通信装置。
背景技术
近年来，随着无线通信技术的快速进步，移动通信系统已经跨代发展。为了满足业务需求的爆炸式增长，包括载波聚合(carrier aggregation，CA)的各种技术已经被引入到通信系统中。在大多数情况下，在终端设备和网络设备(例如，基站)之间的通信中使用单载波。当采用载波聚合时，主载波和一个或多个辅助载波可以被使用在终端设备和网络设备之间的通信中，相比于只使用主载波，可以显著地提高数据传输速率。
在高低频辅助小区协作的场景下，高频辅助小区可以只用作数据传输分流(offloading)，为了节省终端设备功耗，在高频辅助小区无数据传输时，可以去激活高频辅助小区。
终端设备收到网络设备下发的高频辅助小区激活信令后，会进行高频辅助小区的同步信号广播信道块(synchronous signal/PBCH block，SSB)信号发现和测量。由于高频通信基于模拟窄波束的数据接收和发送，因此终端设备在没有任何波束测量信息的前提下，需要使用不同的接收波束扫描接收SSB信号，直到检测到满足一定信号质量的SSB信号，基于检测到的SSB信号和无线资源控制(radio resource control，RRC)配置信息，完成终端设备在高频辅助小区的上下行定时同步、频点同步，完成高频辅助小区激活。当高频辅助小区有多个接收波束时，终端设备决策接收波束的耗时太大，导致辅助小区激活时延过长，降低了通信质量和可靠性。

为便于理解本申请实施例，首先结合图1详细说明适用于本申请实施例的通信系统。
图1是适用于本申请实施例的通信系统100的示意图。如图1所示，该通信系统100包括至少一个网络设备110和至少一个终端设备120。在通信系统100中，终端设备和网络设备可以通过波束管理过程获得通信较优的一个或多个波束对，波束对为<Bx，B’x>以及<By,B’y>，其中Bx代表网络设备的发送波束，B’x代表终端设备的接收波束，By代表终端设备的发送波束，B’y代表网络设备的接收波束。例如，参见图1，网络设备的发送波束#1和终端设备的接收波束#0为一个波束对，网络设备的发送波束#2和终端设备的接收波束#2为一个波束对。终端设备的发送波束#0和网络设备的接收波束#1为一个波束对，终端设备的发送波束#1和网络设备的接收波束#2为一个波束对。
在通信系统100中需要终端设备120和网络设备110的波束对齐才能进行正常的通信。由于终端设备和网络设备都能各自朝向多个波束方向，因此进行通信的前提是需要有正确的波束指示。具体来讲，在下行通信中，网络设备需要通知终端设备应该使用什么接收波束接收接下来网络设备发送的信号，或者通知终端设备接下来网络设备发送的信号是使用什么发送波束发送的。在上行通信中，网络设备需要通知终端设备应该使用什么发送波束发送上行物理信道和/或下行信号，或者通知终端设备网络设备会使用什么样的接收波束来接收终端发出的信号。比如，在下行传输中，网络设备可以通知终端设备该网络设 备使用发送波束#1进行传输，那么终端设备需要使用接收波束#0进行接收。或者，网络设备使用发送波束#1进行传输，并且通知终端设备使用接收波束#0进行接收。再如，在上行传输中，网络设备可以通知终端设备使用发送波束#0进行传输，那么网络设备将使用接收波束#1进行接收。或者，网络设备可以通知该网络设备使用的接收波束为接收波束#0，从而终端设备需要使用发送波束#0进行传输。
为便于理解本申请实施例，下面首先对本申请中涉及的几个术语做简单介绍。
1、波束：波束是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束成形技术(beamforming)或者其他技术手段。波束成形技术可以具体为数字波束成形技术，模拟波束成形技术，混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。可选的，可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等。
波束，也可以理解为空间资源，可以是指具有能量传输指向性的发送或接收预编码向量。能量传输指向性可以指在一定空间位置内，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等，能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。同一设备(例如网络设备或终端设备)可以有不同的预编码向量，不同的设备也可以有不同的预编码向量，即对应不同的波束，针对设备的配置或者能力，一个设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个波束或者多个波束。从发射和接收两个角度出发，波束可以分为发射波束和接收波束。
发射波束：是指通过多天线采用波束成形技术发射具有方向性的波束。
接收波束：是指接收信号的方向上也具有指向性，尽可能指向发射波束的来波方向，以进一步提高接收信噪比并避免用户间的干扰。
波束也可以称为空域滤波器(spatial filter)，或者称空间滤波器(spatial filter)或空间参数(spatial parameters)，发射波束也可以称为空域发射滤波器，接收波束也可以称为空域接收滤波器。
2、波束配对关系：即，发射波束与接收波束之间的配对关系，也就是空间发射滤波器与空间接收滤波器之间的配对关系。在具有波束配对关系的发射波束和接收波束之间传输信号可以获得较大的波束赋形增益。
在一种实现方式中，发送端和接收端可以通过波束训练来获得波束配对关系。具体地，发送端可通过波束扫描的方式发送参考信号，接收端也可通过波束扫描的方式接收参考信号。具体地，发送端可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束将参考信号发射出去，使得参考信号在发射波束所指向的方向上发射参考信号的功率可以达到最大。接收端也可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束接收参考信号，使得该接收端接收参考信号的功率在接收波束所指向的方向上可以达到最大。
通过遍历各发射波束和接收波束，接收端可基于接收到的参考信号进行信道测量，并将测量得到的结果通过信道状态信息(Channel State Information，CSI)上报发送端。例如， 接收端可以将参考信号接收功率(reference signal receiving power，RSRP)较大的部分参考信号资源上报给发送端，如上报参考信号资源的标识，以便发送端在传输数据或信令时采用信道质量较好的波束配对关系来收发信号。
3、参考信号与参考信号资源：参考信号可用于信道测量或者信道估计等。参考信号资源可用于配置参考信号的传输属性，例如，时频资源位置、端口映射关系、功率因子以及扰码等，具体可参考现有技术。发送端设备可基于参考信号资源发送参考信号，接收端设备可基于参考信号资源接收参考信号。
本申请中涉及的信道测量也包括波束测量，即通过测量参考信号获得波束质量信息，用于衡量波束质量的参数包括RSRP，但不限于此。例如，波束质量也可以通过参考信号接收质量(reference signal receiving quality，RSRQ)，信噪比(signal-noise ratio，SNR)，信号与干扰噪声比(signal to interference plus noise ratio，SINR，简称信干噪比)等参数衡量。本申请实施例中，为方便说明，在未作出特别说明的情况下，所涉及的信道测量可以视为波束测量。
其中，参考信号例如可以包括信道状态信息参考信号(channel state information reference signal，CSI-RS)、同步信号块(synchronization signal block，SSB)以及探测参考信号(sounding reference signal，SRS)、上行控制信道解调参考信号(PUCCH de-modulation reference signal，PUCCH-DMRS)，上行数据信道解调参考信号PUSCH-DMRS，上行相位噪声跟踪信号(phase noise tracking reference signal，PTRS)、物理广播信道解调参考信号(physical broadcast channel de-modulation reference signal，PBCH-DMRS)、下行控制信道解调参考信号PDCCH-DMRS，下行数据信道解调参考信号PDSCH-DMRS、小区信号(cell reference signal，CRS)(NR没有)，精同步信号(tim/frequency tracking reference signal，TRS)(LTE没有)等。与此对应地，参考信号资源可以包括CSI-RS资源(CSI-RS resource)、SSB资源(SSB resource)、SRS资源(SRS resource)、TRS资源、DMRS资源、CRS资源、TRS资源。
需要说明的是，上述SSB也可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)，所对应的SSB资源也可以称为同步信号/物理广播信道块资源(SS/PBCH block resource)，可简称为SSB resource。
为了区分不同的参考信号资源，每个参考信号资源可对应于一个参考信号资源的标识，例如，CSI-RS资源标识(CSI-RS resource indicator，CRI)、SSB资源标识(SSB resource indicator，SSBRI)、SRS资源索引(SRS resource index，SRI)、TRS资源索引(TRS resource index，TRI)、DMRS资源索引(DMRS resource index，DRI)、CRS资源索引(CRS resource index，CRSRI)。
其中，SSB资源标识也可以称为SSB标识(SSB index)。
应理解，上文中列举的参考信号以及相应的参考信号资源仅为示例性说明，不应对本申请构成任何限定，本申请并不排除在未来的协议中定义其他参考信号来实现相同或相似功能的可能。
4、天线端口(antenna port)：简称端口。被接收端设备所识别的发射天线，或者在空间上可以区分的发射天线。针对每个虚拟天线可以配置一个天线端口，每个虚拟天线可以为多个物理天线的加权组合，每个天线端口可以与一个参考信号端口对应。天线端口是 逻辑上的概念，一个天线端口可以对应一个物理发射天线，也可以对应多个物理发射天线。在这两种情况下，终端的接收机(receiver)都不会去分解来自同一个天线端口的信号。因为从终端的角度来看，不管信道是由单个物理发射天线形成的，还是由多个物理发射天线合并而成的，这个天线端口对应的参考信号(reference signal，RS)就定义了这个天线端口，例如，对应解调参考信号(de-modulation reference signal，简称DMRS)的天线端口即DMRS端口，终端都可以根据这个参考信号得到这个天线端口的信道估计。每个天线端口对应一个时频资源网格(time/frequency resource grid)，有其独自的参考信号。一个天线端口就是一个信道，终端需要根据这个天线端口对应的参考信号进行信道估计和数据解调。
5、准共址(quasi-co-location，QCL)：或者称准同位。具有QCL关系的天线端口对应的信号中具有相同的参数，或者，一个天线端口的参数可用于确定与该天线端口具有QCL关系的另一个天线端口的参数，或者，两个天线端口具有相同的参数，或者，两个天线端口间的参数差小于某阈值。其中，该参数可以包括以下一项或多项：时延扩展(delay spread)，多普勒扩展(doppler spread)，多普勒频移(doppler shift)，平均时延(average delay)，平均增益，空间接收参数(spatial Rx parameters)。其中，空间接收参数可以包括以下的一项或多项：到达角(angle of arrival，AOA)、平均AOA、AOA扩展、离开角(angle of departure，AOD)、平均离开角AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数、发射波束、接收波束以及资源标识。
其中，上述角度可以为不同维度的分解值，或不同维度分解值的组合。天线端口为具有不同天线端口编号的天线端口，和/或，具有相同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口，和/或，具有不同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口。资源标识可以包括：CSI-RS资源标识，或SRS资源标识，或SSB资源标识，或物理随机接入信道(physical random access channel，PRACH)上传输的前导序列的资源标识，或解调参考信号(demodulation reference signal，DMRS)的资源标识，用于指示资源上的波束。
在NR协议中，QCL关系可以基于不同的参数分为以下四种类型：
类型A(type A)：多普勒频移、多普勒扩展、平均时延、时延扩展；
类型B(type B)：多普勒频移、多普勒扩展；
类型C(type C)：多普勒频移、平均时延；以及
类型D(type D)：空间接收参数。
本申请实施例所涉及的QCL为类型D的QCL。下文中在没有特别说明的情况下，QCL可以理解为类型D的QCL，即，基于空间接收参数定义的QCL。
当QCL关系指类型D的QCL关系时，可以认为是空域QCL。当天线端口满足空域QCL关系时，下行物理信道和/或下行信号的端口和下行物理信道和/或下行信号的端口之间，或上行物理信道和/或下行信号的端口和上行物理信道和/或下行信号的端口之间的QCL关系，可以是两个信号具有相同的AOA或AOD，用于表示具有相同的接收波束或发射波束。又例如对于下行物理信道和/或下行信号和上行物理信道和/或下行信号间或上行物理信道和/或下行信号与下行物理信道和/或下行信号的端口间的QCL关系，可以是两个信号的AOA和AOD具有对应关系，或两个信号的AOD和AOA具有对应关系，即可 以利用波束互易性，根据下行接收波束确定上行发射波束，或根据上行发射波束确定下行接收波束。
从发送端来看，如果说两个天线端口是空域QCL的，则可以是指这两个天线端口的对应的波束方向在空间上是一致的。从接收端来看，如果说两个天线端口是空域QCL的，则可以是指接收端能够在同一波束方向上接收到这两个天线端口发送的信号。
具有空域QCL关系的端口上传输的信号还可以具有对应的波束，对应的波束包括以下至少之一：相同的接收波束、相同的发射波束、与接收波束对应的发射波束(对应于有互易的场景)、与发射波束对应的接收波束(对应于有互易的场景)。
具有空域QCL关系的端口上传输的信号还可以理解为使用相同的空间滤波器(spatial filter)接收或发送信号。空间滤波器可以为以下至少之一：预编码，天线端口的权值，天线端口的相位偏转，天线端口的幅度增益。
具有空域QCL关系的端口上传输的信号还可以理解为具有对应的波束对连接(beam pair link，BPL)，对应的BPL包括以下至少之一：相同的下行BPL，相同的上行BPL，与下行BPL对应的上行BPL，与上行BPL对应的下行BPL。
因此，空间接收参数(即，类型D的QCL)可以理解为用于指示接收波束的方向信息的参数。
6、准同位假设(QCL assumption)：是指假设两个端口之间是否具有QCL关系。准同位假设的配置和指示可以用来帮助接收端进行信号的接收和解调。例如接收端能假设A端口和B端口具有QCL关系，即可以将A端口上测得的信号的大尺度参数用于B端口上的信号测量和解调。大尺度参数可以包括上述的天线端口的参数。
7、传输配置指示(transmission configuration indicator，TCI)状态：可用于指示两种参考信号之间的QCL关系。每个TCI状态中可以包括服务小区的索引(serve cell index，SCI)、带宽部分(band width part，BWP)标识(identifier，ID)和参考信号资源标识，其中，参考信号资源标识例如可以为以下至少一项：非零功率(non-zero power，NZP)CSI-RS参考信号资源标识(NZP-CSI-RS-ResourceId)、非零功率CSI-RS导频资源集标识(NZP-CSI-RS-ResourceSetId)或SSB索引(SSB-Index)。
其中，服务小区的索引、BWP ID以及参考信号资源标识指的是在波束训练过程中所使用的参考信号资源以及所对应的服务小区和BWP。由于在波束训练过程中，网络设备基于不同的参考信号资源通过不同的发射波束发送参考信号，因此通过不同的发射波束发送的参考信号可以关联不同的参考信号资源；终端设备基于不同的参考信号资源通过不同的接收波束接收参考信号，因此通过不同的接收波束接收的参考信号也可以关联不同的参考信号资源。因此，在波束训练过程中，终端设备可以维护服务小区的索引、BWP ID以及参考信号资源标识与接收波束的对应关系，网络设备可以维护服务小区的索引、BWP ID以及参考信号资源标识与发射波束的对应关系。通过参考信号资源标识，便可以建立接收波束和发射波束之间的配对关系。
在此后的通信过程中，终端设备可以基于网络设备所指示的TCI状态确定接收波束，网络设备可以基于同一TCI状态确定发射波束。
此外，TCI状态可以是全局配置的。在为不同的小区、不同的BWP配置的TCI状态中，若TCI状态的索引相同，则所对应的TCI状态的配置也相同。7、TCI：可用于指示 TCI状态。
8、TCI：可用于指示TCI状态。
在一种实现方式中，网络设备可通过高层信令(如RRC消息)为终端设备配置TCI状态(TCI state)列表，例如，网络设备可以通过RRC消息中的TCI状态增加模式列表(tci-StatesToAddModList)来为终端设备配置TCI状态列表。该TCI状态列表中可以包括多个TCI状态，例如，网络设备可以为每个小区中的每个BWP配置最多64个TCI状态。示例性的，TCI的结构如下:
Figure PCTCN2019127468-appb-000001
TCI中可以包括多种参数，例如，小区编号，带宽部分编号，参考信号标识，同步信号块标识，准共址(quasi collocation，QCL)类型等。
此后，网络设备可以通过高层信令，如媒体访问控制(medium access control control element，MAC CE)激活一个或多个TCI状态。被激活的TCI状态为上述RRC消息所配置的TCI状态列表的一个子集。例如，网络设备可以为每个小区中的每个BWP激活最多8个TCI状态。
此后，网络设备还可以通过物理层信令(如下行控制信息(downlink control information，DCI))中的TCI字段指示一个被选择的TCI状态。该DCI例如可以适用于调度物理下行资源的DCI。
其中，一个TCI状态的配置信息可以包括一个或两个参考信号资源的标识，以及所关联的QCL类型。当QCL关系配置为类型A、或B、或C中的一种时，终端设备可以根据TCI状态的指示，解调PDCCH或物理下行共享信道(physical downlink shared channel，PDSCH)。当QCL关系配置为类型D时，终端设备可以知道网络设备使用哪个发射波束发送信号，进而可以根据前文该的信道测量确定的波束配对关系确定使用哪个接收波束接 收信号。终端设备可以根据物理下行控制信道(physical downlink control channel，PDCCH)上DCI中的TCI字段来确定接收PDSCH的接收波束。
终端设备基于该TCI状态指示决策下行物理信道和/或下行信号的接收波束，或决策上行物理信道和/或上行信号的发送波束；其中，下行物理信道和/或下行信号可以是下述中的一种或多种：同步信号、广播信道、广播信号解调信号、同步信号广播信道块(synchronous signal/PBCH block，SSB)、信道状态信息参考信号(channel state information reference signal，CSI-RS)、小区专用参考信号(cell specific reference signal，CS-RS)、UE专用参考信号(user equipment specific reference signal，US-RS)、下行控制信道解调参考信号(dedicated reference signal，DMRS)，下行数据信道解调参考信号，下行相位噪声跟踪信号中任意一种。上行物理信道和/或下行信号可以是下述中的一种或多种：上行随机接入序列，上行探测参考信号(sounding reference signal，SRS)，上行控制信道解调参考信号，上行数据信道解调参考信号，上行相位噪声跟踪信号任意一种。
需要说明的是，当TCI状态中指示的服务小区与被调度用于给终端设备传输下行物理信道和/或下行信号的服务小区可以不是同一个服务小区时，如，TCI状态中指示的服务小区为小区#0，所配置的参考信号为NZP-CSI-RS-ResourceId#0，而被调度用于终端设备传输下行物理信道和/或下行信号的服务小区为小区#1，终端设备也可以基于该TCI状态确定接收波束。TCI状态所指示的NZP-CSI-RS-ResourceId#0的发射波束是小区#0的网络设备的发射波束，例如记作发射波束#0。终端设备可以基于小区0#的下行接收波束来确定小区1#下行物理信道和/或下行信号的接收波束，或上行物理信道和/或上行信号的发送波束。
一种具体的实现方法，终端设备可以直接使用接收服务小区0#的导频资源NZP-CSI-RS-ResourceId#0的下行接收波束来接收小区#1的下行物理信道和/或下行信号。
一种具体的实现方法，终端设备可以根据接收服务小区0#的导频资源NZP-CSI-RS-ResourceId#0的下行接收波束#0的方向确定小区#1下行物理信道和/或下行信号的接收波束，例如可以是与接收波束#0主瓣指向角度相同、或与接收波束#0波束3dB宽度覆盖相同或相近，或选择全向的接收束来接收小区#1的下行物理信道和/或下行信号。
一种具体的实现方法，终端设备根据接收服务小区0#的导频资源NZP-CSI-RS-ResourceId#0的下行接收波束#0的方向确定小区#1上行物理信道和/或上行信号的发送波束，例如可以是与接收波束#0主瓣指向角度相同、或与接收波束#0波束3dB宽度覆盖相同或相近，或选择全向的发送波束来发送小区#1的上行物理信道和/或下行信号。
9、空间关系(spatial relation，SR)：也可以称为上行TCI(uplink TCI，UL TCI)。与上文所介绍的TCI相似，空间关系可以用于确定上行物理信道和/或上行信号的发送波束。该空间关系可以由波束训练确定。用于波束训练的参考信号例如可以是上行参考信号，如探测参考信号(sounding reference signal，SRS)，也可以是下行参考信号，如上文所列举的SSB或CSI-RS。
每个空间关系可以包括服务小区的索引(ServCellIndex)和参考信号资源标识。其中参考信号资源标识例如可以为以下任意一项：下行BWP ID(downlinkBWP ID)和SSB索引(SSB-Index)、下行BWP ID和非零功率CSI-RS参考信号资源标识 (NZP-CSI-RS-ResourceId)，或上行BWP ID和SRS资源标识(SRS-ResourceId)。
其中，服务小区的索引、BWP ID以及参考信号资源标识指的是在波束训练过程中所使用的参考信号资源以及所对应的服务小区和BWP。一个空间关系用于确定一个发送波束，也就是一个服务小区的索引、一个BWP ID和一个参考信号资源可以用于确定一个发射波束。终端设备可以在波束训练的过程中维护服务小区的索引、BWP ID以及参考信号资源标识与发射波束的对应关系，网络设备可以在波束训练的过程中维护服务小区的索引、BWP ID以及参考信号资源标识与接收波束的对应关系。通过参考信号资源标识，便可以建立起发射波束和接收波束之间的配对关系。
在此后的通信过程中，终端设备可以基于网络设备所指示的空间关系确定发射波束，网络设备可以基于同一空间关系确定接收波束。
此外，每个空间关系还可以包括功率控制信息。该功率控制信息例如可以包括以下至少一项：期望的接收功率、路损参考信号和路损补偿参数α。终端设备可以基于该功率控制信息确定使用怎样的发送功率发送上行物理信道和/或下行信号。
另外，空间关系可以是全局配置的。在为不同的小区、不同的BWP配置的空间关系中，若空间关系的标识相同，则所对应的空间关系的配置也相同。
Figure PCTCN2019127468-appb-000002
在一种实现方式中，网络设备可通过高层信令(如RRC消息)为终端设备配置空间关系列表，该空间关系列表中可以包括多个空间关系，例如，网络设备可以为每个小区每个BWP配置最多64个空间关系。
此后，网络设备可以通过高层信令(如MAC CE)激活一个或多个空间关系。被激活的空间关系为上述RRC消息所配置的空间关系列表的一个子集。例如，网络设备可以为每个小区中的每个BWP激活最多8个TCI状态。网络设备通过MAC CE激活空间关系的具体方式与激活TCI状态的具体方式相同，上文中已经对MAC CE激活TCI状态的具体 方式做了详细说明，为了简洁，这里不再赘述。基于MAC CE的激活，终端设备可以确定上行物理信道和/或下行信号与至少一个空间关系的映射关系。
此后，网络设备可以通过物理层信令(如DCI)中的SRI(SRS resource indicator)字段指示一个被选择的空间关系。该DCI例如可以是用于调度上行授权资源(uplink grant，UL grant)的DCI。终端设备可以基于上文该的上行物理信道和/或下行信号与至少一个空间关系的映射关系以及相应的SRI确定被选择的空间关系。
与下行TCI相似地，一个空间关系的配置信息可以包括一个或两个参考信号资源的标识，终端设备可以根据空间关系指示信息，决策上行物理信道和/或上行信号发送波束，或下行物理信道和/或下行信号的接收波束。
此外，一个空间关系的配置信息可以包括一个或两个参考信号资源的标识，以及所关联的空间滤波。例如，当一个空间关系中配置有一个SSB索引，则终端设备可以通过与该SSB索引对应的空间滤波传输信号。其中，与该SSB索引对应的空间滤波器可以是波束训练过程中用于接收该SSB索引所标识的SSB的空间滤波。
终端设备可以根据PDCCH上DCI中的SRI字段来确定发送物理上行共享信道(physical uplink shared channel，PUSCH)的发射波束。
需要说明的是，当空间关系中指示的服务小区与被调度用于给终端设备传输上行物理信道和/或下行信号的服务小区不是同一个服务小区时，如，空间关系中指示的服务小区为小区#0，所配置的导频资源为小区0#的下行物理信道和/或下行信号0-0#或上行物理信道和/或下行信号0-1#。而被调度用于终端设备传输下行物理信道和/或下行信号的服务小区为小区#1，终端设备也可以基于该空间关系确定小区1#上行物理信道和/或下行信号的发射波束，或下行物理信道和/或下行信号的接收波束。
一种具体的实现方法，终端设备可以直接使用接收服务小区0#的下行物理信道和/或下行信号0-0#的下行接收波束来接收小区#1的下行物理信道和/或下行信号。
一种具体的实现方法，终端设备可以根据接收服务小区0#的下行物理信道和/或下行信号0-0#的下行接收波束#0的方向确定小区#1下行物理信道和/或下行信号的接收波束，例如可以是与接收波束#0主瓣指向角度相同、或与接收波束#0波束3dB宽度覆盖相同或相近，或选择全向的接收束来接收小区#1的下行物理信道和/或下行信号。
一种具体的实现方法，终端设备根据发送服务小区0#的上行物理信道和/或下行信号0-1#的发送波束0#的方向确定小区#1下行物理信道和/或下行信号的接收波束，例如可以是与发送波束#0主瓣指向角度相同、或与发送波束#0波束3dB宽度覆盖相同或相近，或选择全向的接收波束来接收小区#1的下行物理信道和/或下行信号。
一种具体的实现方法，终端设备可以直接使用接收服务小区0#的上行物理信道和/或下行信号0-1#的发送波束来发送小区#1的上行物理信道和/或下行信号。
一种具体的实现方法，终端设备可以根据接收服务小区0#的下行物理信道和/或下行信号0-0#的下行接收波束#0的方向确定小区#1上行物理信道和/或上行信号的发送波束，例如可以是与接收波束#0主瓣指向角度相同、或与接收波束#0波束3dB宽度覆盖相同或相近，或选择全向的发送波束来发送小区#1的上行物理信道和/或下行信号。
一种具体的实现方法，终端设备可以根据接收服务小区0#的下行物理信道和/或下行信号0-0#的接收波束#0的方向确定小区#1上行物理信道和/或上行信号的发送波束，例如 可以是与接收波束#0主瓣指向角度相同、或与接收波束#0波束3dB宽度覆盖相同或相近，或选择全向的发送波束来发送小区#1的上行物理信道和/或下行信号。本申请对此不做限定。
10、小区(cell)：小区是高层从资源管理或移动性管理或服务单元的角度来描述的。每个网络设备的覆盖范围可以被划分为一个或多个服务小区，且该服务小区可以看作由一定频域资源组成。在本申请实施例中，小区可以替换为服务小区或CC。在本申请实施例中，“小区”、“服务小区”和“CC”交替使用，在不强调其区别时，其所要表达的含义是一致的。相似地，“服务小区的索引”、“服务小区的标识(ID)”“小区标识(cell ID)”和“CC标识(CC ID)”交替使用，在不强调其区别时，其所要表达的含义是一致的。
需要说明的是，小区可以网络设备的无线网络的覆盖范围内的区域。在本申请实施例中，不同的小区可以对应不同的网络设备。例如，小区#1中的网络设备和小区#2中的网络设备可以是不同的网络设备，如，基站。也就是说，小区#1和小区#2可以由不同的基站来管理，这种情况下，可以称为小区#1和小区#2共站，或者说，同站。小区#1中的网络设备和小区#2中的网络设备也可以是同一基站的不同的射频处理单元，例如，射频拉远单元(radio remote unit，RRU)，也就是说，小区#1和小区#2可以由同一基站管理，具有相同的基带处理单元和中频处理单元，但具有不同的射频处理单元。本申请对此不做特别限定。
小区可以分为以下几种：
主小区(Primary Cell，PCell)：一个MCG小区，工作在主频段上，UE用来执行初始连接或者重建连接。
辅助小区(Secondary Cell)：如果UE配置了CA功能，在特殊小区之外提供额外的无线资源的小区。
特殊小区(Special Cell)：对于双连接操作，特殊小区指MCG的主小区或者SCG的主辅小区，否则，特殊小区为主小区。
主辅小区(Primary SCG Cell)：对于双连接操作，主辅小区指UE执行同步重配时发送随机接入的小区。
辅小区组(Secondary Cell Group)：对于配置了双连接的UE，一个包含PSCell和其他辅小区的服务小区的子集。
11、载波聚合(carrier aggregation，CA)：为了高效地利用零碎的频谱，系统支持不同载波单元之间的聚合。将2个或2个以上的载波聚合在一起以支持更大的传输带宽的技术可以称为载波聚合。
载波聚合是终端设备特定的，不同终端设备可以配置不同的CC，每个CC可以对应于一个独立的小区。在本申请实施例中，可以将一个CC等同于一个小区。例如，主小区对应主CC(或者称，主载波)，可以是为终端进行初始连接建立的小区，或进行RRC连接重建的小区，或是在切换(handover)过程中指定的主小区。辅助小区对应辅CC(或者称，辅助载波)，可以是在RRC重配置时添加的，用于提供额外的无线资源的小区。
对于处于连接态的终端设备来说，若未配置载波聚合，则该终端设备有一个服务小区；若配置了载波聚合，则该终端设备可以有多个服务小区(serving cell)，可以称为服务小区集合。例如，上文该的主小区和辅小区组成了该终端设备的服务小区(serving cell)集 合。换句话说，服务小区集合包括至少一个主小区和至少一个辅小区。或者说，配置了载波聚合的终端可与1个主小区和多个辅助小区相连。
12、跨载波调度(cross-carrier scheduling)：网络设备在一个CC上发送物理下行控制信道(physical downlink control channel，PDCCH)来调度另一个CC上的数据传输，即，在另一个CC上传输PDSCH，或者，在另一个CC上传输物理上行共享信道(physical uplink shared channel，PDCCH)。更具体地，网络设备可以在一个CC的BWP上发送PDCCH来调度另一个CC上的BWP的PDSCH或PUSCH的传输。即，控制信道在一个CC上传输，而对应的数据信道在另一个CC上传输。
该PDCCH中的下行控制信息(downlink control information，DCI)可以通过载波指示域(carrier indicator field，CIF)域指示被调度的CC。即，CIF可以用于指定该PDCCH对应哪个小区的PDSCH/PUSCH资源。
13、带宽部分(BWP)：由于NR中同一小区中不同终端设备的发射或者接收能力可能是不同的，系统可以为每个终端设备配置相应的带宽，这一部分配置给终端设备的带宽称为BWP，终端设备在自己的BWP上传输。BWP可以是载波上一组连续的频域资源，不同的BWP可以占用的频域资源可以部分重叠，也可以互不重叠。不同的BWP占用的频域资源的带宽可以相同，也可以不同，本申请对此不作限定。
针对不同的终端设备，系统可以配置不同的BWP。为了支持不同的业务，不同的BWP可能会支持不同的配置参数(numerology)。其中，numerology是在NR中新引入的一个概念，具体可理解为通信系统所用的一套参数，例如可包括子载波间隔(subcarrier spacing，SCS)、符号长度、循环前缀(cyclic prefix，CP)长度、资源块(resource block，RB)数、时隙长度、帧格式等。一个小区可以支持一种或者多种numerology，一个BWP可以支持一种numerology。应理解，这里所列举的numerology所包含的具体内容仅为示例性说明，不应对本申请构成任何限定。例如，numerology还可包括NR中所能支持的其他粒度的参数。
综上，不同的BWP可能会配置不同的传输带宽(如，BWP包含的RB数不同)、不同的子载波间隔、不同的循环前缀(cyclic prefix，CP)等。
网络设备在与终端设备传输数据之前，可以预先为终端设备调度物理资源。网络设备可以通过例如PDCCH为终端设备调度PDSCH或PUSCH。若网络设备为终端设备配置了载波聚合，则网络设备发送PDCCH的CC与传输PDSCH或PUSCH的CC可能会不同。例如，在CC#0上发送PDCCH，在CC#1上传输PDSCH或PUSCH，即上文所说的跨载波调度；或者，网络设备发送PDCCH的BWP与传输PDSCH或PUSCH的BWP不同，例如，在CC#0中的BWP#0上发送PDCCH，在CC#0上的BWP#2上传输PDSCH或PUSCH；或者，网络设备发送PDCCH的CC和BWP与传输PDSCH或PUSCH的CC也BWP都不同，例如，在CC#0中的BWP#0上发送PDCCH，在CC#1上的BWP#1上传输PDSCH或PUSCH。
以下行传输为例，网络设备会基于每个CC中的每个BWP为终端设备配置激活的TCI状态。例如，网络设备在CC#0中的BWP#0上发送PDCCH，在CC#1上的BWP#1上传输PDSCH。则终端设备可能预先接收到为CC#0中的BWP#0配置的激活的TCI状态以及为CC#1上的BWP#1配置的激活的TCI状态。
例如，为CC#0中的BWP#0配置的激活的TCI状态包括TCI状态0至7，为CC#1中的BWP#2配置的激活的TCI状态包括TCI状态0、TCI状态4至6。则可以得到表1和表2的映射关系。其中，表1是配置给CC#0中的BWP#0的映射关系，具体如下：
表1
DCI中的3比特TCI字段 RRC中配置的TCI状态
000 TCI状态0
001 TCI状态1
010 TCI状态2
011 TCI状态3
100 TCI状态4
101 TCI状态5
110 TCI状态6
111 TCI状态7
表2是配置给CC#1中的BWP#1的映射关系，具体如下：
表2
DCI中的3比特TCI字段 RRC中配置的TCI状态
000 TCI状态0
001 TCI状态4
010 TCI状态5
011 TCI状态6
可以看到，当所使用的映射关系不同时，TCI字段所指示的TCI状态也不一定相同。例如，TCI字段为“010”时，在表1中对应TCI状态3，在表2中对应TCI状态5。可以理解，TCI状态3和TCI状态5是基于不同的发射波束和/或接收波束训练得到的，由TCI状态3和TCI状态5所确定的发射波束和接收波束都有可能是不同的。
14、载波(component carrier，CC)，或者称为成员载波、组成载波、载波分量等。载波聚合主要是将多个载波单元(component carrier，CC，或者称，成员载波、组成载波、载波等)汇聚成一个具有较大带宽的载波，下行控制信道(physical downlink control channel，PDCCH)和PDSCH在相同的CC或不同的CC中。一个CC可以由一个或者多个BWP组成。在本申请实施例中，小区可以替换为服务小区或CC。在本申请实施例中，“小区”、“服务小区”和“CC”交替使用，在不强调其区别时，其所要表达的含义是一致的。相似地，“服务小区的索引”、“服务小区的标识(ID)”、“小区标识(cell ID)”和“CC标识(CC ID)”交替使用，在不强调其区别时，其所要表达的含义是一致的。
15、波束管理资源：指用于波束管理的资源，又可以体现为用于计算和测量波束质量的资源。波束质量包括层一接收参考信号功率(layer 1reference signal received power,L1-RSRP)，层一接收参考信号质量(layer 1reference signal received quality,L1-RSRQ)等。具体的，波束管理资源可以包括同步信号，广播信道，下行信道测量参考信号，跟踪信号，下行控制信道解调参考信号，下行共享信道解调参考信号，上行探测参考信号，上行随机接入信号等。
16、波束质量：本申请中不限制衡量波束质量的度量指标，可能的指标包括参考信号接收功率(reference signal received power，RSRP)，块误码率(block error rate，BLER)， 参考信号接收质量(reference signal received quality，RSRQ)，参考信号接收强度指示(received signal strength indicator，RSSI)，信号干扰噪声比(signal to interference and noise ratio，SINR)，信号质量指示(channel quality indicator，CQI)，相关性等。
17、天线面板(panel)：无线通信的信号需要由天线进行接收和发送，多个天线单元(antenna element)可以集成在一个面板(panel)上。一个射频链路可以驱动一个或多个天线单元。在本申请实施例中，终端设备可以包括多个天线面板，每个天线面板包括一个或者多个波束。网络设备也可以包括多个天线面板，每个天线面板包括一个或者多个波束。天线面板又可表示为天线阵列(antenna array)或者天线子阵列(antenna subarray)。一个天线面板可以包括一个或多个天线阵列/子阵列。一个天线面板可以有一个或多个晶振(oscillator)控制。射频链路又可以称为接收通道和/或发送通道，接收机支路(receiver branch)等。一个天线面板可以由一个射频链路驱动，也可以由多个射频链路驱动。因此本申请中的天线面板也可以替换为射频链路或者驱动一个天线面板的多个射频链路或者由一个晶振控制的一个或多个射频链路。
作为5G标准的第一个版本，Release 15支持作为5G标准的第一个版本，Release 15支持两种频率范围：频率范围1(即低频，简称FR1，450MHz-6000MHz)以及频率范围2(即高频，简称FR2，24250MHz-52600MHz)。针对FR1频段和FR2频段，基站使用不同的射频通道。通过高频天线阵列规模较大，输出的模拟波束较窄；而低频天线阵列规模较小，输出的模拟波束较宽。
在高低频协作场景下，高频可以只用作数据传输分流(offloading)，当高频没有数据传输时，可以去激活高频辅助小区，配置较长的高频非激活状态测量周期，进而节省终端设备功耗。
在需要高频进行数据传输时，基站通过MAC CE信令下发辅助小区激活信令。基站接收到该激活指令后，基于无线资源RRC配置SSB机器类通信(machine type of communication，MTC)配置，在相应的时间检测窗内检测SSB信号。图2是现有技术中的MAC CE辅助小区激活信令的一种格式的示意图。如图所示，图中的一个八位组(Oct，octet)表示8比特(bits)构成的一个字节(byte)。R为预留比特，C i为激活指示信息，对应RRC配置的成员载波(component carrier，CC)索引，当C i取值为1时，表示激活相应的CC；当C i取值为0时，表示去激活对应的CC，i＝0,2…7。
具体地，该MAC CE中C i用于指示各CC是否被激活。每一个C i可以占用一个比特，例如，C i的值可以是1或0。1可以代表CC被选中激活，0可以代表该CC未被选中激活。值为1的C i最多可以有7个(8个CC，其中一个为主CC，即主小区，一直处于激活状态)。
例如，图2中C 1至C 7为7个激活指示信息，依次对应7个CC1至CC7，若C 1取值为1时，表示激活CC1；若C 1取值为0时，表示激活CC1；若C 1至C 7均取值为1时，则表示激活CC1至CC7。
图3示出了目前技术中MAC CE的另一种格式的示意图。图3中示出了四个八位组(Oct，octet)的MAC CE辅助小区激活信令格式。该MAC CE辅助小区激活信令最多可以配32个激活指示信息，其中C 0对应的CC0为主小区，C 1至C 31对应的CC1至CC31表示31个辅助小区。
由于激活阶段，网络设备没有为终端设备配置任何准共址指示信息，终端设备需要自 己决策接收波束来检测与接收SSB信号，实现辅助小区的上下行同步，完成辅助小区激活。当终端设备装备的多个高频面板时，不同面板可以覆盖多个不同的方向，则在高频辅助小区激活时，需要进行终端设备接收波束扫描，直到找到较好的接收波束成功检测并接收到SSB信号，完成辅助小区激活，整个激活过程耗时较大。按照现有的时延定义，用户最长需要25个SSB时间测量配置(SSB measurement timing configurations，SMTC)周期才能完成小区发现和接收波束扫描，降低了通信质量和可靠性。
有鉴于此，本申请提供一种辅助小区激活的方法，能够在进行辅助小区的激活时，减小辅助小区的激活时延，提高通信质量和可靠性。
下面将结合附图详细说明本申请实施例。
图4是从设备交互的角度示出信号传输的方法400的示意性流程图。如图4所示，图4中示出的方法400可以包括步骤410至步骤430。下面结合图4详细说明方法400中的各个步骤。
应理解，在本申请实施例中，以终端设备和网络设备作为执行方法400的执行主体为例，对方法400进行说明。作为示例而非限定，执行方法400的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
S410，网络设备生成辅助小区的激活信令，该激活信令包括至少一个第一准共址指示信息。
第一准共址指示信息用于指示辅助小区波束信息。可选地，该第一准共址指示信息可以用于指示该终端设备在该辅助小区的激活阶段的下行物理信道和/或下行信号接收波束和/或上行物理信道和/或上行信号发送波束。终端设备在该辅助小区的激活阶段采用该第一准共址指示信息指示波束进行下行物理信道和/或下行信号接收和/或上行物理信道和/或上行信号发送。
可选地，第一准共址指示信息可以基于以下原则确定。在直视镜(line-of-sight，LOS)场景下，可认为高低频信道具有一致性，即通过信道测量确定低频接收波束的最佳接收方向后，终端设备可以在该接收方向上进行波束扫描，检测并接收SSB信号，完成辅助小区的激活，即利用低频信息辅助高频辅助小区的激活。在确定低频最佳接收波束方向后，网络设备可以将指示低频最佳接收方向的接收波束的第一准共址指示信息携带在高频辅助小区的激活信令中。上行情况与下行类似，为了简洁，不再赘述。
应说明，频率范围1(即低频，简称FR1，450MHz-6000MHz)以及频率范围2(即高频，简称FR2，24250MHz-52600MHz)。
可选地，该第一准共址指示信息可以包括传输配置指示状态标识TCI状态ID、导频资源集标识RS resource set ID或空间关系指示信息，本申请实施例对此不作限定。
以第一准共址指示信息为TCI状态ID为例，图5至图7分别示出了三种携带第一准共址指示信息的MAC CE辅助小区激活信令的格式。图5示出了N个Oct的MAC CE辅助小区的激活信令格式，与图2所示的现有的MAC CE辅助小区激活信令的格式相比，图5所示的MAC CE辅助小区的激活信令格式中携带了至少一个TCI状态ID，如图5中的TCI状态ID0、TCI状态ID1等。类似地，图6与图3相比较，图6所示的MAC CE辅助小区的激活信令格式中携带了至少一个TCI状态ID。MAC CE中C i用于指示各CC状态是否被激活。每一个C i可以占用一个比特，TCI状态ID的值对应上文通过RRC消 息中的tci-StatesToAddModList配置的TCI状态列表中的第i个TCI状态。终端设备通过查询TCI状态列表，获取该TCI State ID的值相应的TCI状态。由于在波束训练过程中，终端设备可以维护服务小区的索引、BWP ID以及参考信号资源标识与接收波束的对应关系，网络设备可以维护服务小区的索引、BWP ID以及参考信号资源标识与发射波束的对应关系。终端设备可以基于网络设备所指示的TCI状态确定接收波束，网络设备可以基于同一TCI状态确定发射波束。
可选地，该激活信令还包括多个组成载波CC的指示信息C i，至少一个TCI状态ID与该多个CC具有一定的对应关系：
1、多个TCI状态ID与该多个CC一一对应
TCI状态ID与CC按顺序一一对应。如图5所示的MAC CE辅助小区激活信令的格式中，按编号大小依次配置CC1与TCI状态ID0对应，CC2与TCI状态ID1，以此类推，CC7与TCI状态ID6对应。
2、激活的CC对应一个TCI状态ID
激活信令中，如果只指示信息C 1和C 3取值为1，表示只激活C 1和C 3对应的CC1和CC3，则只配置CC1和CC3所对应的TCI状态ID0和TCI状态ID2。
3、所有CC对应一个TCI状态ID
例如，激活信令中，所有CC都配置TCI状态ID0。当RRC配置的TCI状态列表中存在TCI状态ID0对应的TCI状态信息，则根据该TCI状态信息激活所有的CC；当RRC配置信令里不存在TCI状态ID0对应的TCI配置信息，例如，TCI状态ID0取-1或其它非法值，则终端设备自主决策接收波束。
4、一组CC对应一个TCI状态ID
例如，激活信令中，激活指示信息C 1、C 2、C 3与C 4分别对应的CC1、CC2、CC3及CC4为一组CC，则这一组CC配置TCI状态ID0。又例如，激活指示信息C 1、C 3、C 5与C 7分别对应的CC为一组CC，则这一组CC配置TCI状态ID1，其余依次按顺序配置TCI状态ID2、TCI状态ID3等。
其中，该CC分组方式可以为具有相同带宽的CC为一组、具有相同频带的CC为一组、具有相同接收波束的CC为一组或者具有相同发送波束的CC为一组。
具体分组方式还包括其它分组方式，通过RRC显示配置或隐式通知给终端设备，本申请对此不作限定。
应说明，上述四种对应关系仅仅是举例说明，本申请对此不作限定。
可选地，该MAC CE辅助小区激活信令的格式还可以如图7所示，即在每个CC的指示信息预留1bit，配置相应的TCI状态ID。如果该CC的指示信息中不包括相应的TCI状态ID，则表示终端设备自己决策该CC的接收波束来检测接收SSB信号，完成辅助小区的激活。例如，当CC1的指示信息中包括相应的TCI状态ID0，则根据该TCI状态ID0在TCI状态列表中对应的TCI状态确定接收波束，通过该接收波束检测接收SSB信号，完成辅助小区的激活。
应说明，图5至图7为了便于说明仅示出了本申请实施例的三种MAC CE辅助小区激活信令格式，本申请对此并不作限定。
S420，网络设备向终端设备发送辅助小区的激活信令；
网络设备向终端设备发送该包括第一准共址指示信息的激活信令。该激活信令可以由网络设备通过主小区向终端设备发送MAC CE来实现。
可选地，在终端设备接收网络设备生成的辅助小区激活信令之前，该终端设备接收网络设备发送第一指示信息，该第一指示信息用于指示主小区与该辅助小区的下行定时相同，或主小区与该辅助小区的时间提前组TAG相同。
S430，终端设备根据该激活信令进行辅助小区激活。
终端设备接收到激活信令后，可以根据该激活信令中携带的第一准共址指示信息决策最佳接收波束，并在最佳接收波束的方向上进行波束扫描，接收并检测SSB信号，完成辅助小区的激活。终端设备的具体决策方法，本申请实施例不作限定。
可选地，在该第一准共址指示信息为TCI状态ID时，终端设备接收到辅助小区的激活信令后，根据该激活信令中携带的TCI状态ID决策接收波束，利用TCI状态ID对应的TCI状态确定的接收波束检测接收SSB，完成辅助小区的激活。
例如，若当前主小区为低频，辅助小区为高频，该辅助小区激活信令中携带的TCI状态ID对应的TCI状态列表中“TCI-state--->QCL-Info--->referenceSignal”可以为低频SSB或RS资源，终端设备基于该低频SSB或RS信号最强接收方向，决策高频接收波束集合为该低频信号最强接收方向相同或近似的一个或多个接收波束，终端设备在这一个或多个接收波束中检测接收SSB信号，实现辅助小区的激活。
可选的，终端设备根据基站的配置在该辅助小区进行信道状态信息(channel state information，CSI)测量，将该CSI测量结果上报网络设备，告知网络设备辅助小区激活成功，进而可以进行数据传输。基站的配置可以是RRC配置的周期性的CSI-RS上报，也可以是RRC配置并由MAC-CE激活的半持续的CSI-RS上报，也可以RRC配置并由MAC-CE激活和DCI选择的非周期性的非周期CSI-RS上报。
可选地，该终端设备采用该第一准共址指示信息指示的波束在该辅助小区进行下行物理信道和/或下行信号的接收，和/或，上行物理信道和/或上行信号的发送。
可选地，辅助小区激活后，终端设备可以按照第一准共址指示信息的指示确定下行信道和/或下行物理信道和/或下行信号接收波束，和/或上行信道和/或上行物理信道和/或上行信号发送波束，来接收下行信道和/或下行物理信道和/或下行信号，和/或发送上行信道和/或上行物理信道和/或下行信号。例如下行控制信道，下行数据信道等。如果下行控制信道预先配置了准共址信息，例如PDCCH TCI，终端可以忽略该配置，而按照第一准共址指示信息的接收下行控制信道。
另外，辅助小区激活后，网络设备还可以向终端设备发送第二准共址指示信息。该第二准共址指示信息用于指示终端设备收到该第二波束指示信后的下行物理信道和/或下行信号接收波束和/或上行物理信道和/或上行信号发送波束。该终端设备采用该第二准共址指示信息指示的波束在该辅助小区进行下行物理信道和/或下行信号接收波束，和/或，上行物理信道和/或上行信号发送波束。
终端设备收到第二准共址指示信息与使用第二准共址指示信息之间可能会有一定的时间时隔，需要考虑波束切换时延、和/或天线面板切换时延、和/或RF通道启动时延等。在这种情况下，在该时间间隔后使用第二准共址指示信息。
可选地，该第一准共址指示信息还用于指示终端设备在辅助小区完成激活后到收到该 第二准共址指示信息时的下行物理信道和/或下行信号接收波束和/或上行物理信道和/或上行信号发送波束。也就是说，辅助小区激活后，在未收到该第二准共址指示信息的情况下，终端设备继续使用该第一准共址指示信息确定接收和/或发送波束。
在本申请提供的辅助小区激活的方法中，网络设备在辅助小区的激活信令中携带至少一个第一准共址指示信息，终端设备根据该第一准共址指示信息完成辅助小区的激活，这样可以在不提升终端设备功耗的前提下，减小辅助小区的激活时延，进而提升系统容量和用户业务体验。
目前的技术中，终端设备的初始接入，主要是通过检测接收SSB信号。为了降低终端设备的开销，通常设置SSB信号周期较长。在进行波束扫描时，如果一个周期未结束，只有到第二个周期开始时，才能进行下一个波束扫描，导致波束扫描耗时太长。因此，在激活辅助小区时，可以利用检测接收其它参考信号代替检测周期较长的SSB信号，完成辅助小区的激活，从而减小辅助小区的激活时延，降低终端设备的检测功耗，提高通信质量和可靠性。
作为另一个实施例，该第一准共址指示信息可以为导频资源集标识。图8是从设备交互的角度示出信号传输的方法800的示意性流程图。如图8所示，图8中示出的方法800可以包括步骤810至步骤850。下面结合图8详细说明方法800中的各个步骤。
应理解，在本申请实施例中，以终端设备和网络设备作为执行方法800的执行主体为例，对方法800进行说明。作为示例而非限定，执行方法800的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
S810，终端设备接收网络设备发送的第一指示信息。
该第一指示信息用于指示该终端设备配置主小区与辅助小区的下行定时相同，或时间提前组(timing advance group，TAG)相同。
S820，终端设备根据该第一指示信息配置主小区与辅助小区下行定时相同或TAG相同。
通过配置主小区与辅助小区下行定时相同或TAG相同，实现下行定时同步。
S830，网络设备生成辅助小区的激活信令，该激活信令包括至少一个第一准共址指示信息。
具体地，在本申请实施例中，该第一准共址指示信息可以为导频资源集标识(RS resource set ID)，其中，该RS可以为零功率(zero power，ZP)CSI-RS、NZP CSI-RS，跟踪参考信号TRS、下行控制信道解调参考信号(dedicated reference signal，DMRS)或上行探测参考信号(sounding reference signal，SRS)，本申请对此不作限定。
可选地，该至少一个第一准共址指示信息用于指示该终端设备在该辅助小区的激活阶段的下行物理信道和/或下行信号接收波束和/或上行物理信道和/或上行信号发送波束。
S840，网络设备向终端设备发送辅助小区的激活信令。
该激活信令可以由网络设备通过MAC CE向终端设备发送。图9至图11为本申请实施例中的MAC CE辅助小区激活信令的格式，它们与图5至图7的不同之处在于本申请实施例中激活信令中携带的第一准共址指示信息为RS资源集合ID。相关描述可以参考前述实施例，为了简洁，在此不加赘述。
该至少一个RS资源集合ID与该激活信令包括的多个CC也具有一定的对应关系，该 对应关系和上述TCI状态ID与多个CC的对应关系一致，为了简洁，在此不加赘述。
应说明，该RS资源结合ID关联的参考信号可以为SSB、或RS(NZP CSI-RS、ZP CSI-RS、TRS、DMRS、SRS)资源，为了加快辅助小区激活，该参考信号可以周期性发送、触发式发送或者半静态的发送。具体发送方式，本申请实施例对比不作限定，只要能实现波束快速扫描即可。
另外，该网络设备在向终端设备发送辅助小区激活信令后，可以显式的或隐式的去激活RS资源集合ID所指示的参考信号资源。显式方式则通过网络设备向终端设备发送去激活信令指示终端设备基于上述参考信号资源去激活。
具体的隐式方法是通过其他信令或通过判断是否满足预定义的条件来决策。下面举例说明：
方法一：协议事先约定好，网络设备向终端设备发送辅助小区激活信令后，第一次收到激活辅助小区的CSI测量上报后，会激活上述参考信号资源的发送。
方法二：协议事先约定好，辅助小区激活信令所指示的参考信号资源只在特定的时间段内发送。比如，从网络设备向终端设备发送激活信令开始到协议定义的最大激活时延结束这段时间内发送。
方法三：辅助小区激活信令所指示的参考信号资源只发送一次。比如，从网络设备向终端设备发送激活信令的第n+k(k>＝0)个slot发送一次该参考信号资源。
应理解，上述去激活参考信号资源隐式发送方法仅仅是举例说明，本申请对此不作限定。
S850，终端设备根据该激活信令进行辅助小区激活。
在低频信道根据参考信号确定最佳接收波束后，指示最佳接收波束集合对应的RS资源的ID作为第一准共址指示信息携带在辅助小区的激活指令中，网络设备向终端设备发送该激活指令。终端设备接收到该激活指令后，根据该RS资源集合ID确定相应的RS资源集合，终端设备根据该RS资源集合检测接收参考信号，完成辅助小区激活。
例如，终端设备在接收到辅助小区的激活信令后，在RS资源集合ID所指示的时频域资源位置检测并接收相应的参考信号，完成辅助小区激活。
网络设备根据该激活信令和第一指示信息中的配置信息发送下行参考信号，终端设备根据该配置指示信息发送上行参考信号。
可选地，该终端设备采用该第一准共址指示信息指示的波束在该辅助小区进行下行物理信道和/或下行信号的接收，和/或，上行物理信道和/或上行信号的发送。
可选地，辅助小区激活后，终端设备可以按照第一准共址指示信息的指示确定下行信道和/或下行物理信道和/或下行信号接收波束，和/或上行信道和/或上行物理信道和/或上行信号发送波束，来接收下行信道和/或下行物理信道和/或下行信号，和/或发送上行信道和/或上行物理信道和/或下行信号。例如下行控制信道，下行数据信道等。如果下行控制信道预先配置了准共址信息，例如PDCCH TCI，终端可以忽略该配置，而按照第一准共址指示信息的接收下行控制信道。
另外，辅助小区激活后，网络设备还可以向终端设备发送第二准共址指示信息。该第二准共址指示信息用于指示终端设备收到该第二波束指示信后的下行物理信道和/或下行信号接收波束和/或上行物理信道和/或上行信号发送波束。该终端设备采用该第二准共址指示信息指示的波束在该辅助小区进行下行物理信道和/或下行信号接收，和/或，上行物 理信道和/或上行信号发送。
本申请实施例提供的辅助小区的激活的方法，用检测接收其它参考信号代替检测接收周期较长的SSB信号，通过持续性地发送参考信号，能够在较短的时间内完成接收波束扫描，减小辅助小区的激活时延，提升系统容量和用户业务体验。
目前的技术中，在激活辅助小区时，网络设备没有给终端设备配置任何准共址指示信息，终端设备在激活辅助小区时，只能进行盲检，自己决策最佳接收波束，检测接收SSB信号，实现辅助小区激活，这造成辅助小区激活时延过大。在高低频共站址的场景下，由于主小区一般为低频，而主小区只能处于激活状态，不能被去激活。因此，在高低频下行定时相同或TAG相同时，在做高频辅助小区激活时，可以利用高频SSB参考低频的参考信号，利用低频测量辅助实现高频辅助小区的激活。
图12是从设备交互的角度示出信号传输的方法1200的示意性流程图。如图12所示，图12中示出的方法1200可以包括步骤1210至步骤1260。下面结合图12详细说明方法1200中的各个步骤。
应理解，在本申请实施例中，以终端设备和网络设备作为执行方法1200的执行主体为例，对方法1200进行说明。作为示例而非限定，执行方法1200的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
S1210，终端设备接收网络设备发送的RRC配置信令。
该RRC配置信令包括：同步广播信号块SSB资源信息和该SSB资源的准共址QCL指示信息。
该终端设备在接收到该RRC配置信令后，根据该RRC配置信令指示的准共址指示信息接收该辅助小区的SSB。
例如，在终端设备接收到激活信令之前，网络设备通过“CSI-MeasConfig---->csi-SSB-ResourceSetToAddModList---->CSI-SSB-ResourceSet”将SSB相应的信道质量指示(Channel Quality Information，CQI)信息配置给终端设备。
另外，网络设备通过TCI-StateId定义SSB的QCL指示，其中，TCI-StateId所指示的“TCI-state--->QCL-Info--->referenceSignal”可以是低频cell的SSB、或RS(NZP CSI-RS、ZP CSI-RS、TRS、DMRS、SRS)信号，也可以是高频cell的SSB、或RS(NZP CSI-RS、ZP CSI-RS、TRS、DMRS、SRS)信号。具体信令如下：
Figure PCTCN2019127468-appb-000003
可选地，该终端设备接收第二指示信息，该第二指示信息用于指示该终端设备配置主小区与该辅助小区的的下行定时相同或时间提前组TAG相同。
S1220，网络设备发送第二指示信息。
终端设备接收该第二指示信息，该第二指示信息用于指示主小区与该辅助小区的下行定时相同，和/或主小区与该辅助小区的时间提前组TAG相同。
S1230，终端设备根据该第二指示信息配置主小区与辅助小区下行定时相同或TAG相同。该步骤可选。
终端设备根据第二指示信息配置主小区与辅助小区下行定时相同或TAG相同，实现高低频下行定时相同。
S1240，网络设备生成辅助小区的激活信令。
该激活信令格式可以与现有辅助小区激活信令格式相同，具体可参考图2和图3，为了简洁，此处不再赘述。
S1250，网络设备向终端设备发送辅助小区的激活信令。
该激活信令可以通过MAC CE发送给终端设备。
S1260，终端设备根据该激活信令和该准共址指示信息进行辅助小区激活。
由于SSB是周期性的，并具有时间偏移量。因此在得到低频定时后，可以知道SSB可能会在哪几个符号上发送，终端设备可以决策接收波束，在SSB发送时去检测并接收SSB信号，实现辅助小区的激活。
例如，由于RRC配置信令配置高低频TAG相同，则根据SSB周期和当前低频定时可确定SSB在第1个符号至第4个符号内出现，从而终端设备可以在第1个符号至第4个符号利用接收波束接收检测SSB信号，完成辅助小区激活。
本申请实施例中，在高低频共站址的场景下，在辅助小区激活之前，通过RRC配置信令配置高低频小区的TAG相同，实现下行定时相同，将低频信道参考信号作为SSB的QCL参考，基于低频信道的测量辅助终端设备决策高频SSB的接收波束，检测接收SSB信号，实现辅助小区的激活。
应理解，在本申请的各个实施例中，第一、第二等只是为了表示多个对象是不同的。例如第一准共址指示信息和第二准共址指示信息只是为了区别出不同的准共址指示信息。而不应该对准共址指示信息本身产生任何影响，上述的第一、第二等不应该对本申请的实施例造成任何限制。
