下面对本申请中涉及的概念进行描述：
波束(beam)：
波束是一种通信资源，波束可以是宽波束、窄波束，或者其他类型波束。形成波束的技术可以是波束赋形技术或者其他技术手段。波束赋形技术可以通过在空间上朝 向特定的方向来实现更高的天线阵列增益。波束赋形技术可以具体包括数字波束赋形技术、模拟波束赋形技术、混合数字/模拟波束成形技术，例如，模拟波束赋形技术可以通过移相器实现，一个射频链路(RF chain)通过移相器来调整相位，从而控制模拟波束方向的改变，因此一个射频链路在同一时刻只能发射一个模拟波束。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，例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。波束在协议中的体现还是可以空域滤波器(spatial filter)，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。
波束管理资源：
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 1 reference signal received power，L1-RSRP)、层一接收参考信号质量(layer 1 reference 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。
波束指示信息：
波束指示信息用于指示传输所使用的波束(包括发送波束和/或接收波束)。波束指示信息包括波束编号、波束管理资源编号、上行信号资源号、下行信号资源号、波束的绝对索引、波束的相对索引、波束的逻辑索引、波束对应的天线端口的索引、波束对应的天线端口组索引、波束对应的下行信号的索引、波束对应的下行同步信号块的时间索引、波束对连接(beam pair link，BPL)信息、波束对应的发送参数(Tx parameter)、波束对应的接收参数(Rx parameter)、波束对应的发送权重、波束对应的权重矩阵、波束对应的权重向量、波束对应的接收权重、波束对应的发送权重的索引、波束对应的权重矩阵的索引、波束对应的权重向量的索引、波束对应的接收权重的索引、波束对应的接收码本、波束对应的发送码本、波束对应的接收码本的索引、波束对应的发送码本的索引中的至少一种。下行信号包括同步信号、广播信道、广播信号解调信号、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)、用户设备专用参考信号(user equipment specific reference signal，US-RS)、下行控制信道解调参考信号、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。上行信号包括中上行随机接入序列、上行探测参考信号、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。可选的，网络设备还可以为频率资源组关联的波束中具有准同位(quasi-collocation，QCL)关系的波束分配QCL标示符。波束指示信息还可以体现为传输配置编号(transmission configuration index，TCI)，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、QCL类型等。
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功率(reference signal received power，RSRP)、参考信号质量(reference signal received quality，RSRQ)、块误码率(block error rate，BLER)、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。
准同位(quasi-co-location，QCL)：
同位关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征，对于具有同位关系的多个资源，可以采用相同或者类似的通信配置。例如，如果两个天线端口具有同位关系，那么一个端口传送一个符号的信道大尺度特性可以从另一个端口传送一个符号的信道大尺度特性推断出来。大尺度特性可以包括：延迟扩展、平均延迟、多普勒扩展、多普勒频移、平均增益、接收参数、终端设备接收波束编号、发射/接收信道相关性、接收到达角、接收机天线的空间相关性、主到达角(angel-of-arrival，AoA)、平均到达角、AoA的扩展等。
空域准同位(spatial QCL)：
空域准同位可以认为是QCL的一种类型。对于空域有两个角度可以理解：从发送端或者从接收端。从发送端来看，如果说两个天线端口是空域准同位的，那么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准同位的，那么是指接收端能够在相同的波束方向上接收到这两个天线端口发送的信号。
准同位假设(QCL assumption)：
准同位假设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。例如接收端能确认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。
同时接收：
本申请所提到的同时接收包括接收端(例如终端设备)在一个接收参数上接收到多个信号，也包括在多个可同时使用的接收参数上接收到多个信号。
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)可以集成在一个天线面板上。一个射频链路可以驱动一个或多个天线单元。在本申请中，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，终端设备包括多个天线面板时，每一个天线面板都可以朝向一个方向，即可实现全方向的发送和接收。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。
载波聚合(carrier aggregation，CA)：
为了满足单用户峰值速率和系统容量提升的要求，一种最直接的办法就是增加系统传输带宽。长期演进(long term evolution advanced，LTE-A)引入一项增加传输带宽的技术，也就是载波聚合。CA将多个LTE成员载波(component carrier，CC)聚合在一起，每个CC对应一个小区，增加系统传输带宽，有效提高了上下行传输速率。终端设备根据自己的能力大小决定最多可以同时利用几个载波进行上下行传输。
载波聚合中的小区包括主小区和辅小区。主小区是运行在主频点上的小区，在这个小区中，终端设备既进行初始的连接建立过程或者发起重建立过程，也作为切换过程中的主小区。辅小区是运行在辅频点上的小区，在这个小区中，通过主小区配置来建立一个无线资源控制(radio resource control，RRC)连接，用来提供额外的无线资源。
对于没有配置CA的连接态终端设备而言，只有一个主小区作为服务小区。而对于配置了CA的连接态终端设备而言，服务小区用于表示主小区和辅小区组成的一个或多个小区。
首先介绍下现有技术中辅小区激活方法，用于终端设备和网络设备激活辅小区。如图4所示，该方法包括：
S401、终端设备在网络设备的主小区进行初始接入，网络设备为终端设备配置辅小区。

可选的，辅小区的配置参数还可以包括周期性导频测量及上报资源、CC初始或默认部分带宽(bandwidth part，BWP)配置、CC移动测量配置等。
S402、网络设备动态决策为终端设备启动辅小区传输，并向终端设备发送辅小区激活信令。
相应地，终端设备从网络设备接收辅小区激活信令。
具体的，网络设备可以通过媒体访问控制控制信元(media access control control element，MAC-CE)信令向终端设备发送辅小区激活信令。
3GPP R15协议规定的辅小区激活信令如图5A或图5B所示，其中，图5A为一个字节的MAC-CE，图5B为四个字节的MAC-CE。Ci指示辅小区索引(sCellIndex)为i的辅小区进行激活或去激活，Ci设置为0指示辅小区索引(sCellIndex)为i的辅小区进行去激活，Ci设置为1指示辅小区索引(sCellIndex)为i的辅小区进行激活。R为保留位。
S403、终端设备进行辅小区下行时频域同步。
具体的，终端设备根据RRC信令中的SSB-MTC确定SSB发送的时频域位置，在相应的时间窗内检测辅小区的SSB信号，实现辅小区下行时频域同步。进一步的，终端设备在通过SSB完成下行时频域同步的前提下，通过接收其他导频信号(例如，跟踪参考信号(tracking reference signal，TRS)、或相位跟踪参考信号(phase tracking reference signal，PTRS)、或非零功率信道状态信息参考信号资源(non-zero power channel state information reference signal resource，NZP-CSI-RS))完成更高精度的下行时频域同步。
如果当前激活辅小区为FR2-CC，FR2没有任何已激活服务小区，且终端设备没有任何FR2的收发波束参考信息，则终端设备在辅小区激活阶段需要进行收发波束扫描，选取合适的收发波束对用于激活阶段，并基于该收发波束对实现辅小区下行时频域同步。
S404、终端设备对辅小区激活阶段的CSI进行测量，向网络设备发送辅小区激活阶段的CSI测量结果。
相应地，网络设备从终端设备接收辅小区激活阶段的CSI测量结果。
根据RRC信令配置的导频资源实现对辅小区激活阶段的CSI进行测量。根据RRC信令配置的上报资源上报辅小区激活阶段的CSI测量结果。
S405、网络设备接收到上报的辅小区激活阶段的CSI测量结果后，确定终端设备完成辅小区激活，能够通过辅小区与终端设备进行数据传输。
另外，如果网络设备在下发辅小区激活信令后的T时刻还未收到上报的辅小区激活阶段的CSI测量结果，则确定辅小区激活失败。
上述辅小区激活方法有如下缺点。
缺点一：
针对高频仅下行传输(DL-only)的场景，当高频没有上行信道时，则无法上报辅小区激活阶段的CSI测量结果，终端设备只能基于添加辅小区时配置的辅小区周期性导频资源对辅小区激活阶段的CSI进行测量。
原因在于，每CC可配的最大导频资源数量(例如，NZP-CSI-RS resources)属于终端设备能力上报参数，有效取值为1～32。而每CC最大可配SSB资源数量为64。在网络设备通过RRC信令为终端设备配置辅小区的配置参数时，需要基于终端设备上报的每CC可配的最大导频资源数量，从小区级CSI-RS资源内选取部分CSI-RS资源配置给终端设备，当配置的CSI-RS资源所承载的波束不包含终端设备的服务波束时， 终端设备无法对辅小区激活阶段的CSI进行测量，从而导致辅小区激活失败。
缺点二：
针对高低频协作场景，高频可以只用作数据传输的流量转移(offloading)，当高频没有数据传输时，可以去激活高频辅小区。为节省终端设备的功耗，则可配置较长的高频非激活态测量周期；在需要高频做数据传输时，激活高频辅小区。此时，如果终端设备装备了多个高频天线面板，不同的天线面板可以覆盖多个不同的方向，则辅小区激活时需要终端设备进行接收波束扫描，直到找到较好的接收波束来成功检测SSB，完成下行同步；基于RRC信令配置的用于CSI测量的导频资源与上报资源，对辅小区激活阶段的CSI进行测量并上报测量结果，整个过程需要较长的处理时延，严重影响业务拥塞场景下的用户业务体验。
本申请实施例提供的辅小区激活方法，通过网络设备指示终端设备上报辅小区激活阶段的信道状态信息测量结果的上行资源，实现了终端设备将辅小区激活阶段的信道状态信息测量结果上报给网络设备。进一步地，通过网络设备配置用于信道状态信息测量的导频资源，使终端设备可以直接对该导频资源进行CSI测量来降低处理时延。
