Description

一种波束信息上报与接收方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种波束信息上报与接收方法及装置。
背景技术
在现有通信系统中，网络设备可以通过配置载波聚合(carrier aggregation，CA)来提升系统容量。CA是指将多个分量载波(component carrier，CC)聚合在一起，以支持更大传输带宽的技术。其中，在CA聚合的多个CC中包括主分量载波(primary component carrier，PCC)，和辅分量载波(secondary component carrier，SCC)。PCC对应的小区称为主小区(primary cell，Pcell)，SCC对应的小区称为辅小区(secondary cell，Scell)。辅小区中包括具有发送物理上行控制信道(physical uplink control channel，PUCCH)能力的辅小区，可简称为PUCCH辅小区，和/或，普通的不具有发送PUCCH能力的辅小区。在PUCCH辅小区的激活过程中，终端设备如何向网络设备上报PUCCH辅小区的波束信息，是本申请实施例待解决的技术问题。
发明内容
本申请提供一种波束信息上报与接收方法及装置，以实现第一小区的波束信息上报。
第一方面，提供一种波束信息上报方法，包括：终端设备接收来自网络设备的第一激活信令，所述第一激活信令用于激活第一小区，所述第一小区为具有物理上行控制信道PUCCH的辅小区；所述终端设备对所述第一小区的参考信号进行测量，确定所述第一小区的波束信息；所述终端设备通过第二小区，向网络设备发送层2信令，所述层2信令中包括所述第一小区的波束信息，所述第二小区为所述第一小区对应的主小区或主辅助小区。
通过上述方法，在第一小区的激活过程中，终端设备可利用第二小区上报第一小区的波束信息，从而使得网络设备可以获取第一小区的波束信息，从而实现第一小区的激活。
在一种可能的实现方式中，上述层2信令包括媒体接入控制控制元素MAC CE信令。
在一种可能的实现方式中，上述方法还包括：所述终端设备响应于所述第一激活信令，判断所述第一小区是否为未知小区；如果所述第一小区为未知小区，则执行所述终端设备对所述第一小区的参考信号进行测量，确定所述第一小区的波束信息的步骤。
由于对于已知小区，已上报过第一小区的波信息，无需再继续上报。只有未知小区，才需要进行第一小区的波束上报。在本申请实施例中，对第一小区的参考信号进行测量，确定第一小区的波束信息之前，先判断一下第一小区是否为未知小区。从而避免对于已知小区再执行参考信号测量和波束上报的流程，节省终端设备的功耗和信令开销。
可选的，在所述终端设备通过第二小区，向网络设备发送层2信令之后，还包括：所述终端设备向网络设备发送有效的信道状态信息CSI，所述有效的CSI表示所述第一小区的激活完成。
通过上述方法，整个方案的流程可以为：网络设备向终端设备发送第一小区的激活信令；终端设备响应于上述激活信令，通过第二小区上报第一小区的波束信息；网络设备基于上报的第一小区的波束信息，可为终端设备配置TCI，和/或上行空间关系等，TCI用于 指示终端设备接收下行信息的波束，上行空间关系用于指示终端设备发送上行信息的波束。终端设备向网络设备发送有效的CSI，代表第一小区的激活完成。通过上述可以看出，在本申请实施例中，可以在第一小区的激活过程中，通过第二小区上报第一小区的波束信息。
在一种可能的实现方式中，上述终端设备对所述第一小区的参考信号进行测量，确定所述第一小区的波束信息的过程，包括：所述终端设备对所述第一小区的参考信号进行测量，得到参考信号的测量结果；所述终端设备在所述第一小区的参考信号中，选择测量结果满足条件的参考信号；所述第一小区的波束信息中包括所述测量结果满足条件的参考信号的指示信息，和/或所述测量结果满足条件的参考信号的层1-参考信号接收功率L1-RSRP。
其中，上述终端设备对所述第一小区的参考信号进行测量的过程，包括：所述第一小区预配置有CSI测量配置，所述终端设备对所述第一小区预配置的CSI测量配置中包括的参考信号进行测量；或者，所述第一小区预配置有第一参考信号列表，所述终端设备对所述第一小区预配置的第一参考信号列表中包括的参考信号进行测量。
第二方面，提供一种波束信息接收方法，包括：网络设备向终端设备发送第一激活信令，所述第一激活信令用于激活第一小区，所述第一小区为具有PUCCH的辅小区；所述网络设备通过第二小区，接收来自所述终端设备的层2信令，所述层2信令中包括所述第一小区的波束信息，所述第二小区为所述第一小区的主小区或主辅助小区。
通过上述方法，在第一小区的激活过程中，网络设备可以通过第二小区，接收第一小区的波束信息，从而实现对第一小区的激活。
在一种可能的实现方式中，上述层2信令包括MAC CE信令；和/或，上述第一小区为未知小区。
在一种可能的方案中，在网络设备通过第二小区，接收来自所述终端设备的层2信令之后，还可以包括：所述网络设备接收来自终端设备的有效的CSI，所述有效的CSI表示所述第一小区的激活完成。
可选的，网络设备通过第二小区接收的第一小区的波束信息中可以包括测量结果满足条件的参考信号的指示信息，和/或所述测量结果满足条件的参考信号的L1-RSRP。
第三方面，提供一种波束信息上报方法，包括：终端设备接收来自网络设备的第一激活信令，所述第一激活信令用于激活第一小区，所述第一小区为具有PUCCH的辅小区；所述终端设备对所述第一小区的参考信号进行测量，确定第一波束信息；所述终端设备利用第一波束信息关联的第一随机接入资源和第一随机接入前导码，在所述第一小区中向网络设备发起随机接入。
通过上述方法，终端设备通过第一小区关联的随机接入资源和随机接入前导码，向网络设备隐示上报第一小区的波束信息，节省信令开销。
在一种可能的实现方式中，第一波束可以关联至少一个随机接入资源和至少一个随机接入前导码。所述终端设备可以在第一波束信息关联的至少一个随机接入资源中，选择第一随机接入资源；在至少一个随机接入前导码中，选择第一随机接入前导码。可以理解的是，上述过程是可选的。若第一波束仅关联一个随机接入前导码和一个随机接入资源的情况下，终端设备无需执行上述选择的过程，终端设备关联的一个随机接入资源即为上述第一随机接入资源，终端设备关联的一个随机接入前导码即为上述第一随机接入前导码。
在一种可能的实现方式中，上述方法还包括：所述终端设备响应于所述第一激活信令， 判断所述第一小区是否为未知小区；如果所述第一小区为未知小区，则执行所述终端设备对第一小区的参考信号进行测量，确定第一波束信息的步骤。
可选的，在所述终端设备利用第一波束信息关联的第一随机接入资源和第一随机接入前导码，在所述第一小区中向网络设备发起随机接入之后，还包括：所述终端设备向网络设备发送有效的CSI，所述有效的CSI表示所述第一小区的激活完成。
通过上述方法，整个方案至少包括：网络设备向终端设备发送第一小区的激活信令，终端设备响应于第一小区的激活信令，确定第一小区的第一波束信息；终端设备确定第一波信息对应的第一随机接入资源和第一随机接入前导码；终端设备基于上述第一随机接入资源和第一随机接入前导码发起随机接入，从而可以实现终端设备通过随机接入过程，隐示的上报第一小区的波束信息，无需额外上报第一小区的波束信息，节省上报第一小区的波束信息的信令开销。
在一种可能的实现方式中，所述终端设备对所述第一小区的参考信号进行测量，确定第一波束信息，包括：所述终端设备对第一小区的参考信号进行测量，得到参考信号测量结果；所述终端设备在第一小区的参考信号中，选择参考信号测量结果满足条件的参考信号，所述第一波束信息中包括所述测量结果满足条件的参考信号的指示信息，和/或所述测量结果满足条件的参考信号的L1-RSRP。
可选的，在终端设备基于第一小区的波束信息发起随机接入之前，还包括：所述终端设备判断所述第一小区的定时提前量TAG定时提前TA是否失效；如果所述第一小区的TAG TA失效，则执行所述终端设备利用第一波束信息关联的第一随机接入资源和第一随机接入前导码，在所述第一小区中向网络设备发起随机接入的步骤。如果第一小区的TAG TA未知效，可以采用其它方式上报第一小区的波束信息。例如通过上述第一方面的方法上报第一小区的波束信息等。
在本申请实施例中，在以下条件下可以认为第一小区的TAG TA有效：包含第一小区的TAG关联的时间校准定时器(time alignment timer)正在运行，则认为第一小区的TA有效，否则认为第一小区的TA失效。可选的，TA失效还可称为TA过期等。在无线通信过程中，若终端设备侧的TA失效，通常意味着终端设备与网络设备无法严格的保持时间上的同步，此时终端设备需要重新发起随机接入，网络设备在终端设备的随机接入过程中，为终端设备分配有效的TA。现有协议中规定，辅小区的随机接入只能受PDCCH命令(order)的触发。辅小区的随机接入过程可能为：终端设备向网络上报波束信息，网络设备基于终端设备上报的波束信息，从中选择一个波束，且在该波束中向终端设备发送PDCCH命令(order)，终端设备基于上述PDCCH命令的触发，发起随机接入，获取有效的TA。而在上述方案中，当终端设备确定第一小区的TA的失效时，直接基于第一小区的波束信息关联的第一随机接入资源和第一随机接入前导码，发起随机接入，既向网络设备隐示的上报了第一小区的波束信息，又可以在随机接入过程中获取网络设备为其分配的有效的TA，相对于当前协作中规定的先上报辅小区的波束信息，再由网络设备发送PDCCH命令，触发终端设备随机接入的过程，简化终端设备获取有效TA的流程，节省了信令开销。
第四方面，提供一种波束信息接收方法，包括：网络设备向终端设备发送第一激活信令，所述第一激活信令用于激活第一小区，所述第一小区为具有PUCCH的辅小区；所述网络设备利用第一随机接入资源，在所述第一小区中接收来自终端设备的第一随机接入前 导码；所述第一随机接入资源和所述第一随机接入前导码关联的第一波束信息，为所述第一小区的波束信息。可选的，所述第一小区可以为未知小区，和/或，所述第一小区的TAG TA失效。
其中，所述第一波束的信息中可以包括测量结果满足条件的参考信号的指示信息，和/或所述测量结果满足条件的参考信号的L1-RSRP。
在一种可能的实现方式中，所述第一波束信息关联至少一个随机接入资源和至少一个随机接入前导码，所述至少一个随机接入资源中包括所述第一随机接入资源，所述至少一个随机接入前导码中包括所述第一随机接入前导码。
可选的，在所述网络设备利用第一随机接入资源，在所述第一小区中接收来自终端设备的第一随机接入前导码之后，还包括：所述网络设备接收来自向终端设备的有效的CSI，所述有效的CSI表示所述第一小区的激活完成。

通过上述方法，当满足预设条件时，终端设备直接停止在第二小区中周期性上报第一小区的波束信息。相对于目前的方案中，由于第二小区中配置有第一小区的波束上报，即便在第一小区已成功激活时，第二小区仍上报第一小区的波束信息，除非通过RRC信令重配，删除第二小区中配置的第一小区上报。在本申请实施例中，无需RRC信令重配，即可停止在第二小区中上报第一小区的波束信息，节省信令开销。
在一种可能的实现方式中，上述预设条件中包括以下至少一项：所述终端设备接收到来自网络设备的传输配置指示TCI，和/或上行空间关系指示；所述终端设备在所述第二小区中发送第一个有效的第一小区的CSI；所述终端设备向所述网络设备发送有效的CSI，所述有效的CSI表示所述第一小区的激活完成；所述终端设备接收来自网络设备的物理下行控制信道PDCCH命令，或者有效的TA信息，所述PDCCH命令用于触发所述终端设备的随机接入，所述PDCCH命令中包括所述第一小区的波束信息，所述有效的TA信息为在所述终端设备在随机接入过程中，网络设备为所述终端设备分配的。在本申请实施例中，当满足上述预设条件中的一项或多项时，终端设备可以停止在第二小区中上报第一小区的波束信息。

在一种可能的实现方式中，上述方法还包括：所述网络设备接收来自所述终端设备的有效的CSI，所述有效的CSI表示所述第一小区的激活完成。
在一种可能的实现方案中，网络设备在发送第一激活信令时，还可能需要判断第一小区是否为未知小区。如果第一小区是未知小区，则网络设备可以根据第一小区的波束信息，为第一小区配置TCI和/或上行空间关系等。

该网络架构100还包括位于网络设备110覆盖范围内的一个或多个终端设备120。该终端设备120可以是移动的或固定的。该终端设备120可以简称为终端，是一种具有无线收发功能的设备。终端设备可以部署在陆地上，包括室内或室外，手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self driving)中的无线终端设备、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、和/或智慧家庭(smart home)中的无线终端设备。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备或计算设备、车载设备、可穿戴设备，未来第五代(the 5th generation，5G)网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等。终端设备有时也可以称为用户设备(user equipment，UE)，终端设备120可以与不同技术的多个接入网设备进行通信，例如，终端设备可以与支持长期演进(long term evolution，LTE)的接入网设备通信，也可以与支持5G的接入网设备通信，还可以与支持LTE的接入网设备以及支持5G的接入网设备的双连接。本申请实施例并不限定。
本申请实施例中，用于实现终端设备的功能的装置可以是终端设备；也可以是能够支持终端设备实现该功能的装置，例如电路系统，该装置可以被安装在终端设备中。本申请 实施例中，电路系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中，以用于实现终端设备的功能的装置是终端设备为例，描述本申请实施例提供的技术方案。
其中，网络设备110和终端设备120可以通过空口资源进行数据传输。所述空口资源可以包括时域资源、频域资源、码域资源和空间资源中的至少一种。具体来说，网络设备110和终端设备120进行数据传输时，网络设备110可以通过控制信道，如物理下行控制信道(physical downlink control channel，PDCCH)向终端设备120发送控制信息，从而为终端设备120分配数据信道的传输参数，如分配物理下行共享信道(physical downlink shared channel，PDSCH)或物理上行共享信道(physical uplink shared channel，PUSCH)的资源。比如，该控制信息可以指示数据信道所映射至的时域符号和/或频域资源块(resource block，RB)，网络设备110和终端设备120在该分配的时频资源上，通过数据信道进行数据传输。上述数据传输可以包括下行数据传输和/或上行数据传输，下行数据(如PDSCH携带的数据)传输可以指网络设备110向终端设备120发送数据，上行数据(如PUSCH携带的数据)传输可以指终端设备120向网络设备110发送数据。数据可以是广义的数据，比如可以是用户数据、也可以是系统消息，广播信息，或其他的信息等。
图1示例出了一个网络设备和两个终端设备。可选的，该网络架构100可以包括多个网络设备并且一个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对比不作限定。
可以理解的是，上述描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。比如，本申请实施例所提供的技术方案，可以应用于第四代(4th generation，4G)网络架构，例如长期演进(long term evolution，LTE)系统；第五代(5th generation，5G)网络架构，例如新无线(new radio，NR)系统；或未来各种演进的网络架构等，例如物联网、车联网、第六代(6th generation，6G)网络架构等，不作限定。
在图1所示的网络架构中，提出了物理上行控制信道(physical uplink control channel，PUCCH)辅小区的概念，该PUCCH辅小区是指具有发送PUCCH能力的小区，这与普通的辅小区不同。普通的辅小区是不具有发送PUCCH的能力的，普通的辅小区只能通过对应的主小区或主辅助小区或PUCCH辅小区发送PUCCH。针对PUCCH辅小区，提出了以下激活过程：
网络设备向终端设备发送媒体接入控制(media access control，MAC)激活信令，终端设备在接收到MAC激活信令时，对待激活的PUCCH辅小区预配置的参考信号(reference signal，RS)进行测量，得到波束信息，且向网络设备上报波束信息；网络设备根据终端设备上报的波束信息，为该终端设备配置传输配置指示(transmission configuration indicator，TCI)和上行空间关系等；终端设备在TCI的指示，在待激活PUCCH辅小区的PUCCH上向网络设备发送有效的信道状态信息(channel state information，CSI)报告，此时意味PUCCH辅小区的激活完成。可选的，上述激活过程仅为示意性说明，并不作为对本申请实施例的限定。例如，上述激活过程中，可能还包括小区搜索、自动增益控制(automatic gain control，AGC)和定时等过程。在PUCCH辅小区的激活过程中，终端设备如何向网络设备上报PUCCH辅小区的波束信息，是本申请实施例待解决的技术问 题。
针对上述，本申请实施例提供多种解决方案，第一种解决方案，可具体为终端设备在PUCCH辅小区对应的主小区或主辅助小区上发送层2信令，该层2信令中包括PUCCH辅小区的波束信息，具体可参见下述实施例一的记载。第二种解决方案，可具体为终端设备通过PUCCH辅小区的波束信息关联的随机接入资源与随机接入前导码，隐示向网络设备上报PUCCH辅小区的波束信息，具体可参见下述实施例二的记载。第三种解决方案，可具体为通过在主小区或主辅助小区配置PUCCH辅小区的波束信息上报，终端设备可以在主小区或主辅助小区周期性上报PUCCH辅小区的波束信息，且在满足预定条件时，停止在主小区或主辅助小区周期性上报PUCCH辅小区的波束信息，具体可参见下述实施例三的记载。
为了便于理解，以下对本申请涉及的通信名词或术语进行解释说明：
1、主小区(primary cell，PCell)
主小区可以是终端设备进行初始连接建立的小区，或者，主小区可以是终端设备进行无线资源控制(radio resource control，RRC)连接重建的小区，或者，主小区可以是在切换(handover)过程中指定的主小区等。主小区，主要用于与终端设备之间的RRC通信。主小区对应的分量载波称为主分量载波(primary component carrier，PCC)。
2、主辅助小区(primary secondary cell，PSCell)
主辅助小区是在双连接(dual connectivity，DC)中提出的概念。为了便于理解，首先介绍下双连接：由于单个基站的带宽资源和覆盖范围有限。因此，LTE和NR中引入了双连接技术，用于提供基站间非理想传输条件下的性能解决方案。在一种双连接方案中，用户数据流在分组数据汇聚协议(packet data convergence protocol，PDCP)层进行分割和合并，之后将用户数据流通过多个不同的基站同时传输给终端设备，从而获得大带宽和高速率。在其它双连接方案中，用户数据流可以在其它位置，例如核心网侧,进行分割或合并，之后将用户数据流通过多个不同的基站同时传输给终端设备。其中，上述多个基站中的一个基站为主站(master node，MN)，剩余的基站为辅站(secondary node，SN)。MN与SN可以采用同一无线制式，或者不同的无线制式，不作限定。例如，MN可采用LTE制式，SN可采用NR制式。
如图2所示，在双连接中存在主小区组(master cell group，MCG)和辅小区组(secondary cell group，SCG)的概念。在一种可能的解释中，终端设备首先发起随机接入的小区所在的组可以认为是MCG。如果没有DC，也就没有MCG和SCG的概念。或者可以认为，如果没有DC，则终端设备所接入的小区组即为主小区组。
继续参见图2，在MCG中可能存在多个小区，其中上述多个小区中用于终端设备发起随机接入的小区，称为主小区。该MCG中除主小区外的其它小区，称为辅小区。MCG中的主小区和辅小区可以通过载波聚合技术联合在一起。与MCG类似，在SCG中用于终端设备发起随机接入的小区，称为主辅助小区，除主辅助小区外，SCG中的其它小区称为辅小区，主辅助小区和上述其它的辅小区通过载波聚合技术联合在一起。
3、载波聚合(carrier aggregation，CA)
载波聚合是将多个载波分量(component carrier，CC)聚合在一起，以支持更大传输带宽的技术。为了高效地利用零碎的频谱，载波聚合支持不同载波分量之间的聚合。比如，相同或不同带宽内载波分量的聚合，或者同一带宽内，邻接或非邻接的载波分量的聚合， 或者不同带宽内载波分量之间的聚合等。示例的，上述图2中，主小区对应的载波分量可以为主载波分量(primary component carrier，PCC)，辅小区对应的载波分量可以为辅载波分量(secondary component carrier，SCC)。
4、辅小区(secondary cell，Scell)
辅小区可以是与终端设备之间不存在RRC通信的小区，主要用于提供额外的无线资源。所述辅小区可以是在RRC重配置时添加的。在一种示例中，主小区可以是在连接建立时确定的，辅小区可以是在初始接入完成之后，通过RRC连接重配置消息添加、修改或释放的。
5、波束
波束在协议中的体现可以是空域滤波器(spatial domain filter)，或者称空间滤波器(spatial filter)或空间参数(spatial parameter)等。用于发送信号的波束可以称为发送波束(transmission beam，Tx beam)，或者可以称为空域发送滤波器(spatial domain transmission filter)，或者可以称为空间发射参数(spatial transmission parameter)等。用于接收信号的波束可以称为接收波束(reception beam，Rx beam)，或者可以称为空域接收滤波器(spatial domain receive filter)，或者可以称为空间接收参数(spatial RX parameter)等。发送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。
除此之外，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，其中A，B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
实施例一
该实施例一提供一种波束信息上报与接收方法，该方法可用于PUCCH辅小区在激活过程中上报波束信息，该方法包括：终端设备接收来自网络设备的第一激活信令，所述第一激活信令用于激活第一小区，第一小区为具有PUCCH的辅小区；终端设备对第一小区的参考信号进行测量，确定第一小区的波束信息；终端设备通过第二小区，向网络设备发送层2信令，所述层2信令中包括第一小区的波束信息，所述第二小区为第一小区对应的主小区或主辅助小区。
如图3所示，提供一种波束信息上报与接收方法的流程，该流程至少包括：
步骤S301：网络设备向终端设备发送第一激活信令，第一激活信令用于激活第一小区，第一小区为具有PUCCH的辅小区。可选的，第一激活信令可为MAC激活信令等。
步骤S302：终端设备响应于第一激活信令，判断第一小区是否为未知小区。如果第 一小区为未知小区时，执行步骤303。如果第一小区为已知小区，则代表终端设备已经向网络设备上报过第一小区的波束信息，终端设备无需再利用下述步骤303和步骤304的流程向网络设备上报第一小区的波束信息。由于本申请重点关注，对于未知小区，在激活过程中，如何向网络设备上报波束信息，对已知小区的激活过程并不限制，也不再作过多介绍。为了便于说明，在图3用“结束流程”来表示。其中，上述步骤302是可选的。
在一种示例中，如果第一小区是频率范围1(frequency range 1，FR1)的小区，则当第一小区满足以下条件时，则终端设备认为第一小区是已知小区：否则，终端设备认为第一小区是未知小区。
1、在接收到激活命令之前的一段时间内，终端设备上报过第一小区的有效测量结果。
2、在终端设备的激活过程中，以及在激活过程之前的一段时间内，终端设备测量的第一小区的参考信号始终保持可检测条件，可检测条件可包括以下至少一项：第一小区的参考信号的信噪比(signal to interference plus noise ratio，SINR)大于或等于第一预设值，第一小区的参考信号的干扰功率谱密度大于或等于第二预设值，或者，第一小区的参考信号接收功率大于或等于第三预设值等。
在另一种示例中，如果第一小区是频率范围2(frequency range 2，FR2)的小区，当第一小区满足以下条件时，则终端设备认为第一小区是已知小区；否则认为第一小区是未知小区。
1、终端设备在收到最新的TCI激活命令和半静态信道状态信息参考信号(channel state information reference signal，CSI-RS)激活命令之前一段时间内，终端设备上报过有效的参考信号的层3-参考信号接收功率(layer3reference signal receiving power，L3-RSRP)测量。
2、终端设备在L3-RSRP上报之后收到第一小区的激活信号，并且该激活信令不晚于终端设备收到的TCI。
3、终端设备上报的参考信号在L3-RSRP上报到有效的信道质量指示(channel quality indication，CQI)上报期间始终保持可检测，关于可检测条件可参见上述，不再赘述，并且TCI是基于终端设备最近上报的一个或多个参考信号配置的。
步骤S303：终端设备对所述第一小区的参考信号进行测量，得到第一小区的波束信息。
在一种示例中，终端设备可对第一小区的参考信号进行测量，得到参考信号的测量结果；终端设备在第一小区的参考信号中，选择测量结果满足条件的参考信号；第一小区的波束信息中包括测量结果满足条件的参考信号的指示信息，和/或测量结果满足条件的参考信号的层1-参考信号接收功率(layer1reference signal receiving power，L1-RSRP)。
示例的，终端设备对第一小区的参考信号进行测量的过程，可如下：第一小区预配置有CSI测量配置，终端设备可对第一小区预配置的CSI测量配置中包括的参考信号进行测量，或者，第一小区预配置有第一参考信号列表，终端设备可对第一小区预配置的第一参考信号列表中包括的参考信号进行测量。
步骤S304：终端设备通过第二小区，向网络设备发送层2信令，该层2信令中包括所述第一小区的波束信息，所述第二小区为所述第一小区对应的主小区或主辅助小区。可选的，层2信令可以为媒体接入控制控制元素(media access control control element，MAC CE)等。示例的，在终端设备与网络设备的通信协议中，第一层可为物理(physical，PHY) 层，第二层可为MAC层，第三层可为无线链路控制(radio link control，RLC)层，第四层可以为PDCP层，第五层可以RRC层。上述层2信令可以指在上述MAC层发送的信令。当然上述协议栈仅为示意性说明，并不作为对本申请实施例的限定。
在本申请实施例中，上述第一小区与第二小区可位于同一个小区组，该小区组可为主小区组或辅小区组。通过上述图2的描述可知，在DC中，引入了主小区组和辅小区组的概念。主小区组中包括用于随机制接入的小区，称为主小区。该主小区组中除主小区外，还包括辅小区。举例来说，若主小区组1中包括主小区和待激活的PUCCH辅小区。待激活的PUCCH辅小区可为上述第一小区，主小区组1中包括的主小区可以为上述第二小区。与上述类似，辅小区组包括用于随机接入的小区，称为主辅助小区。该辅小区组中除包括主辅助小区外，还可包括辅小区。举例来说，若辅小区组1中包括主辅助小区和待激活的PUCCH辅小区。待激活的PUCCH辅小区可为上述第一小区，主辅助小区可为上述第二小区。
步骤S305：终端设备向网络设备发送有效的CSI，所述有效的CSI表示第一小区的激活完成。其中，上述步骤305是可选的。
需要说明的是，在本申请实施例中，关于第一小区的波束信息可以作如下解释：可预先设置波束与参考信号的对应关系，即设置不同的参考信号采用不同的波束进行收发。例如，绑定参考信号1与波束1的对应关系，参考信号2与波束2的对应关系，参考信号3与波束3的对应关系。那么终端设备通过对参考信号1、参考信号2和参考信号3分别进行测量，比如，测量上述3个参考信号的参考信号接收功率(reference signal receiving power，RSRP)，在上述3个参考信号的RSRP中选择RSRP最大的参考信号，或者RSRP大于阈值的参考信号，作为满足条件的参考信号。上述满足条件的参考信号可认为是在第一小区的传输环境中，满足条件，即在第一小区可用于数据传输的波束。之后，终端设备可通过第二小区，上报第一小区中满足条件的参考信号的指示信息。或者，终端设备可以直接向网络设备上报其所测量的参考信号的RSRP。网络设备根据终端设备上报的参考信号的RSRP，选择满足条件的参考信号；网络设备可根据上述预先设置的参考信号与波束的对应关系，确定上述满足条件的参考信号所对应的波束，可称为满足条件的波束。网络设备可认为上述满足条件的波束为在第一小区的传输环境中传输质量较好的波束。由于波束具有互易性，一波束下行传输质量较好，通常也意味着上行传输质量也较好。因此，网络设备可根据上述满足条件的波束为终端设备配置TCI，和/或上行空间关系。关于TCI可认为是网络设备为终端设备配置的用于接收下行信号的波束，上行空间关系可以认为是网络设备为终端设备配置的用于发送上行信号的波束。之后，终端设备可根据网络设备为其配置的上行空间关系，确定第一波束，且在第一小区中利用该第一波束发送有效的CSI，该有效的CSI代表第一小区的激活完成。
需要说明的是，在本申请有些描述中，是以终端设备上报满足条件的参考信号的指示信息为例进行说明的，但终端设备除上报满条件的参考信号的指示信息外，还可以上报满足条件的参考信号的RSRP。同理，在本申请有些描述中，是以终端设备上报参考信号的RSRP为例进行说明的，但终端设备除上报参考信号的RSRP外，还可以上报终端设备的指示信息，本申请实施对此不作限定。
在本申请的描述中，是以上报“第一小区的波束信息”为例进行描述的，上述“第一小区的波束信息”实际上可以为“第一小区的参考信号信息”或“第一小区的CSI”等。其 中，关于参考信号可包括CSI-RS，或者同步信号块(synchronization signal block，SSB)等，因此，上述“第一小区的波束信息”可以称为“第一小区的SSB信息”或“第一小区的CSI-RS信息”等。终端设备上报的第一小区的参考信号信息可以具体为第一小区中满足条件或终端设备测量的第一小区中参考信号的标识，和/或，第一小区中满足条件或终端设备测量的第一小区中参考信号的L1-RSRP。关于L1-RSRP作如下说明：L1-RSRP的结构中包括参考信号标识，参考信号的RSRP。比如，对于参考信号1，终端设备测量的RSRP为50分贝毫瓦，则该参考信号1对应的L1-RSRP中可包括：参考信号1的标识“1”，以及参考信号1的RSRP“50”等。需要说明的是，为了便于理解，在上述描述中以终端设备直接上报参考信号的RSRP的值为例进行描述，并不作限对本申请实施例的限定。比如，在一种实现中，为了减少上报RSRP的开销，会将RSRP值量化为其它值来上报。比如，可以预先将RSRP值分为几个档位，终端设备直接上报每个RSRP值所在档位的值。或者，可以仅上报最大RSRP的值，其它RSRP仅上报与最大RSRP的差值等。
而关于第一小区的CSI作如下说明：由于CSI中通常包括CQI和参考信号的RSRP。其中，如果终端设备基于SSB测量CSI，则上述CSI中包括的参考信号RSRP具体为SSB-RSRP，而若终端设备基于CSI-RS测量CSI，则上述CSI中包括的参考信号RSRP具体为CSI-RS-RSRP等。CSI中的CQI一般指下行信道质量，由终端设备测量，网络设备可根据终端设备上报的CQI为其选择合适的调度算法和下行数据块大小，以保证终端设备在不同的无线环境下获取较佳的下行性能。可选的，在上述步骤305中，终端设备上报有效的CSI，以表示第一小区的激活完成，还可替换为：终端设备上报有效的CQI，以表示第一小区的激活完成。
针对上述实施例一，提供一种具体的示例，该示例至少包括：
1、对于支持CA且支持PUCCH辅小区的终端设备，在添加了PUCCH辅小区后，网络设备发送MAC激活命令激活该PUCCH辅小区。
在一种示例中，可以预先为终端设备添加至少一个PUCCH辅小区，且添加该PUCCH辅小区的CSI测量配置，CSI测量配置中可包括至少一个CSI上报配置，每个CSI上报配置中包括用于信道测量的CSI资源配置，该CSI上报配置可指示其包括的CSI资源配置对应的参考信号对应的上报方式，例如，是否周期上报、上报类型、上报哪些小区的CSI等。在本申请实施例中，当为终端设备添加PUCCH辅小区后，该PUCCH辅小区还不能使用，即终端设备还不能利用该辅小区与网络设备进行上/下行数据传输。只有该添加的PUCCH辅小区，被激活后，该PUCCH辅小区才可以使用，即终端设备可利用激活的PUCCH辅小区与网络设备进行上/下行数据传输。
2、若上述待激活的PUCCH辅小区为未知小区，则终端设备可以对PUCCH辅小区配置的参考信号进行测量，获得N个参考信号，终端设备通过在主小区或主辅助小区上报MAC CE指示上述N个RS，和/或通过MAC CE上报N个RS的L1-RSRP结果。关于N个参考信号作如下说明：上述N个参考信号可以为终端设备测量的全部参考信号，即终端设备测量多少参考信号，则向网络设备上报多少参考信号，后续选择参考信号的过程可由网络设备侧执行。或者，终端设备可以从所测量的全部参考信号中，选择N个参考信号。关于这N个参考信号可以是终端设备随机选取的，或者基于某种规则，例如，选取的RSRP最好的N个参考信号，或者选取的RSRP大于阈值的参考信号等，不作限定。
关于终端设备对PUCCH辅小区配置的参考信号进行测量的过程，可包括：UE可以 基于PUCCH辅小区预配置的CSI测量配置中包括的至少一个CSI上报配置进行参考信号测量。例如，在一种可能的实现中，设定CSI测量配置中包括X个CSI上报配置，终端设备可以在上述X个CSI上报配置中，选择Y个CSI上报配置，X和Y均为正整数，且Y的取值小于或等于X。每个CSI上报配置中包括用于信道测量的CSI资源配置，终端设备可以对Y个CSI上报配置所对应的所有参考信号进行测量，从中选择N个RS。或者，可以单独为终端设备配置一个参考信号列表，该参考信号列表中包括至少一个参考信号，终端设备可以对上述参考信号列表中包括的参考信号进行测量，从中选择N个RS。
通过上述实施例一，对于未知小区的PUCCH辅小区，在PUCCH辅小区激活前，终端设备还无法通过自己的PUCCH反馈波束信息，通过主小区或主辅助小区上报PUCCH辅小区的波束信息，使得网络设备可以获取该PUCCH辅小区的波束信息，便于后续网络设备为终端设备配置TCI和上行空间关系等。相对目前方案，可以实现PUCCH辅小区的盲添加，在网络不知道终端设备的波束信息的情况下，通过主小区或辅助主小区的MAC CE上报PUCCH辅小区的波束信息。
实施例二
该实施例二提供一种波束信息上报与接收方法，该方法用于未激活的PUCCH辅小区的波束信息上报，该方法至少包括：终端设备接收来自网络设备的第一激活信令，所述第一激活信令用于激活第一小区，第一小区为具有PUCCH的辅小区；终端设备对第一小区的参考信号进行测量，确定第一波束信息；所述终端设备利用第一波束信息关联的第一随机接入资源和第一随机接入前导码，在所述第一小区中向网络设备发起随机接入。
如图4所示，提供一种波束信息上报与接收方法的流程，至少包括：
步骤S401：网络设备向终端设备发送第一激活信令，该第一激活信令用于激活第一小区，第一小区为具有PUCCH的小区。
步骤S402：所述终端设备响应于所述第一激活信令，判断所述第一小区是否为未知小区；如果第一小区为未知小区，执行下述步骤S403。如果第一小区是已知小区，则结束流程。其中，上述步骤S402是可选的。
步骤S403：所述终端设备对所述第一小区的参考信号进行测量，确定第一波束信息。
关于上述步骤S401至S403的过程，可参见上述实施例一中步骤S301至步骤S303的过程，不再赘述。
步骤S404：终端设备判断第一小区的定时提前量组(timing advance group，TAG)定时提前(timing advance，TA)是否失效；如果第一小区的TAG TA失效，则执行下述S404的步骤上报第一小区的波束信息。否则可利用其它方案，向网络设备上报第一小区的波束信息，例如实施例一的方案等。其中，上述步骤S404是可选的。
示例的，在以下条件下可以认为第一小区的TAG TA有效：包含第一小区的TAG关联的时间校准定时器(time alignment timer)正在运行，则认为第一小区的TA有效，否则认为第一小区的TA失效。可选的，TA失效还可称为TA过期等。在无线通信过程中，若终端设备侧的TA失效，通常意味着终端设备与网络设备无法严格的保持时间上的同步，此时终端设备需要重新发起随机接入，网络设备在终端设备的随机接入过程中，为终端设备分配有效的TA。现有协议中规定，辅小区的随机接入只能受PDCCH命令(order)的触发。辅小区的随机接入过程可能为：终端设备向网络上报波束信息，网络设备基于终端 设备上报的波束信息，从中选择一个波束，且在该波束中向终端设备发送PDCCH命令(order)，终端设备基于上述PDCCH命令的触发，发起随机接入，获取有效的TA。而在本申请实施例中，当终端设备确定第一小区的TA的失效时，直接基于第一小区的波束信息关联的第一随机接入资源和第一随机接入前导码，发起随机接入，既向网络设备隐示的上报了第一小区的波束信息，又可以在随机接入过程中获取网络设备为其分配的有效的TA，相对于当前协作中规定的先上报辅小区的波束信息，再由网络设备发送PDCCH命令，触发终端设备随机接入的过程，简化终端设备获取有效TA的流程，节省了信令开销。
步骤S405：所述终端设备在第一波束信息关联的至少一个随机接入资源和至少一个随机接入前导码中，选择第一随机接入资源和第一随机接入前导码。其中，上述步骤S405是可选的，上述步骤S405主要应用于第一波束信息关联的随机接入资源和随机接入前导码均为多个，终端设备需要在多个随机接入资源中选择第一随机接入资源，在多个随机接入前导码中选择第一随机接入前导码的场景。若第一波束关联的随机接入资源和随机接入前导码均为一个，则无需执行上述步骤S405，第一波束关联的随机接入资源即为第一随机接入资源，第一波束关联的随机接入前导码即为第一随机接入前导码。
步骤S406：所述终端设备利用第一波束信息关联的第一随机接入资源和第一随机接入前导码，在所述第一小区中向网络设备发起随机接入。
其中，在上述步骤S406中，网络设备可利用第一随机接入资源，在第一小区中接收来自终端设备的第一随机接入前导码。网络设备可认为第一随机接入资源和第一随机接入前导码关联的第一波束信息，即为第一小区的波束信息。
可选的，上述终端设备无需网络设备的PDCCH命令的触发，直接基于第一波束信息关联的第一随机接入资源和第一随机接入前导码发起随机接入的过程。关于终端设备确定第一波束信息关联的第一随机接入资源和第一资源接入前导码，且发起随机接入的过程，包括但不限于以下两种方案：
第一种：终端设备在确定第一波束信息之后，可在公共的随机接入资源池中，确定第一波束信息关联的第一随机接入资源和第一随机接入前导码。由于该公共的随机接入资源池可以供至少一个终端设备使用，因此该方案还可称为基于竞争的随机接入过程。在一种示例中，上述基于竞争的随机接入包括4个步骤，具体为：
1，终端设备在随机接入信道中发送随机接入前导码。
2，网络设备在检测到随机接入前导码后，发送下行随机接入响应，该下行随机接入响应中至少包括以下信息：
-所收到的随机接入前导码的编号。
-TA信息。
-为该终端设备分配的上行资源位置指示信息。
-临时分配的小区无线网络临时标识(cell-radio network temporary identifier，C-RNTI)。
3，终端设备在收到随机接入响应后，根据其指示，在分配的上行资源上发送上行消息。
4，网络设备接收终端设备的上行消息，并向接入成功的终端设备返回冲突解决消息。
第二种：为终端设备配置专用的参考信号列表和专用的随机接入资源，该专用的参考信号和专用的随机接入资源，用于终端设备向网络设备上报波束信息。终端设备可以对专用的参考信列表中包括的参考信号进行测量，确定第一波束信息；基于专用的参考信号与 专用的资源池的对应关系，在专用的资源池中，确定第一波束信息对应的第一随机接入资源和第一随机接入前导码。本申请实施例中，对终端设备基于专用的随机接入资源池发起随机接入的过程不作限定。
步骤S407：终端设备向网络设备发送有效的CSI，有效的CSI表示第一小区的激活完成。其中，上述步骤S407是可选的。
针对实施例二，提供一种具体的示例，该方法包括：
1、对于支持CA且支持PUCCH辅小区的终端设备，在添加了PUCCH辅小区后，网络设备发送MAC激活信令激活该PUCCH辅小区。
2、若上述待激活的PUCCH辅小区为未知小区，则终端设备自主发起基于竞争的随机接入，过程为：终端设备通过对上述待激活的PUCCH辅小区的参考信号进行测量，选定第一参考信号。基于第一参考信号关联的第一随机接入资源和第一随机接入前导码发送随机接入。
其中，终端设备可基于待激活的PUCCH的预配置的参考信号测量配置或参考信号列表，对参考信号进行测量等，过程与上述类似，不再赘述。
可选的，在上述步骤2之前，终端设备还可判断待激活的PUCCH辅小区所在TAG TA是否过期；若TAG TA过期，则采用本申请实施例二的方案，否则采用其它方案，例如采用上述实施例一的方案。
通过上述，对于未知小区的PUCCH辅小区，终端设备无法在PUCCH辅小区的PUCCH中反馈PUCCH辅小区的波束信息，终端设备选择上述PUCCH辅小区的波束信息关联的随机接入前导码和随机接入资源发起随机接入，从而向网络设备隐示上报PUCCH辅小区的波束信息。通过上述实施例三的方案，可以实现PUCCH辅小区的盲添加，在网络不知道终端设备波束信息的情况下，通过发起随机接入向网络指示PUCCH辅小区的波束信息。
实施例三
该实施例三提供一种波束信息上报与接收方法，该方法可用于PUCCH辅小区在激活过程中向网络设备上报波束信息，该方法至少包括：终端设备接收来自网络设备的第一激活信令，所述第一激活信令用于激活第一小区，所述第一小区为具有PUCCH的辅小区；第二小区中预配置有所述第一小区的波束信息上报，所述终端设备在所述第二小区中，周期性向网络设备发送所述第一小区的波束信息，所述第二小区为所述第一小区的主小区或主辅助小区；所述第一终端设备在满足预设条件时，停止在所述第二小区中，周期性上报所述第一小区的全部或部分波束信息。
如图5所示，提供一种波束信息上报与接收方法的流程，至少包括以下步骤：
步骤S501：网络设备向终端设备发送第一激活信令，该第一激活信令用于激活第一小区，第一小区为具有PUCCH的辅小区。
步骤S502：第二小区中预配置有第一小区的波束上报，终端设备在第二小区中，周期性向网络设备发送第一小区的波束信息，第二小区为第一小区的主小区或主辅助小区。相应的，网络设备发送第一激活信令时，需要判断第一小区是否为未知小区。如果第一小区是未知小区，则网络设备可以根据第一小区的波束信息，为第一小区配置TCI和/或上行空间关系等。
示例的，第二小区中预配置有第一小区的波束上报，可具体包括：在第二小区中配置的第一小区的波束上报为周期性的，即通过第二小区周期性上报第一小区的波束信息。具体的执行过程，可参见下述步骤503和步骤504中的记载。或者，在第二小区中配置的第一小区的波束上报为非周期性的，则终端设备在第二小区中可以非周期上报第一小区的波束信息。在一种示例中，网络设备可以向终端设备发送非周期上报的触发信令，终端设备接收到上述触发信令时，可以通过第二小区上报一次第一小区的波束信息。
在本申请实施例中，关于非周期上报第一小区的波束信息的时间应当不早于，即晚于或等于以下时间：时隙n的时间+第一时间T，时隙n为终端设备接收到激活第一小区的激活信令的时隙。网络需要保证至少有一次非周期波束上报的时间不早于上述规定的时间。例如，在一种示例中，终端设备接收到上述第一小区的激活信令的时隙n的时刻为2021年1月12日14点33秒35毫秒，上述第一时间T的取值为15毫秒，那么需要保证至少一次非周期上报第一小区的波束信息的时间不早于2021年1月12日14点33秒50毫秒。在一种示例中，关于第一时间T可以满足以下公式：
T HARQ+K+T FirstSSB_MAX+15*T SMTC_MAX+8*T rs+T L1-RSRP,measure。
其中，T HARQ表示：从承载第一激活信令的下行传输到反馈对应的HARQ反馈的时间。
K表示：时间常数，例如K的取值可以为3ms等。
T FirstSSB_MAX表示：从
Figure PCTCN2021071667-appb-000001
到第一个完整SSB结束的时间。对于单频段(intra-band)载波聚合场景，为同频段(band)内所有已激活SCell和待激活SCell的SSB在相同时隙slot传输的SSB。对于多频段(inter-band))载波聚合场景，为待激活Scell的SSB。
T SMTC_MAX表示：待激活辅小区的基于SSB的测量定时配(SSB-based measurement timing configuration，SMTC周期，或待激活SCell的SMTC周期与同频段(band)已激活SCell的SMTC周期较大的值。
Trs表示：待激活小区的SMTC周期，如果没配置则为同频点同子载波间隔(sub-carrier spacing，SCS)间隔配置的测量目标中的SMTC周期，否则为规定值。
T L1-RSRP,measure表示：L1-RSRP的测量时间。
在另一示例中，若第一小区位于FR1频段，则上述第一时间T满足以下公式：
T HARQ+K+T FirstSSB_MAX+T SMTC_MAX+T rs+T L1-RSRP,measure
关于该公式中各个参数的含义，可参见上述，不再赘述。
步骤S503：在满足预设条件时，终端设备停止在第二小区中，周期性上报第一小区的全部或部分波束信息。
步骤S504：终端设备向网络设备发送有效的CSI，所述有效的CSI表示第一小区的激活完成。其中，上述步骤S504是可选的。
在该实施例三中，第一小区可以为未知小区，或者已知小区，不作限定。由于第二小区中预配置有第一小区的波束上报，那么终端设备可以通过第二小区，向网络设备上报第 一小区的波束信息。本申请实施例中的重点是，在满足预设条件时，该预设条件至少表示网络设备已经获得第一小区的波束信息，则终端设备此时可停止通过第二小区向网络设备上报第一小区的波束信息。在一些示例中，上述预定条件可包括以下至少一项：
1、终端设备接收到来自网络设备的第一小区的TCI，和/或第一小区的上行空间关系指示。由于网络设备在接收到终端设备的第一小区的波束信息时，才会为终端设备分配第一小区的TCI，和/或第一小区的上行空间关系等。因此，当终端设备接收到网络设备的第一小区的TCI，和/或第一小区的上行空间关系时，表示网络设备已经获取第一小区的波束信息，所以终端设备可以停止向网络设备上报第一小区的波束信息。
2、终端设备在所述第二小区中发送第一个有效的第一小区的CSI。该第一个有效的第一小区的CSI中包括第一小区的波束信息，针对该条件可以如此理解，不考虑网络设备的接收情况，只要向网络设备发送过的有效的第一小区的波束信息，则不再继续发送。
3、终端设备向所述网络设备发送有效的CSI，所述有效的CSI表示所述第一小区的激活完成。由于在第一小区的激活完成时，第一小区可以通过第一小区向网络设备上报第一小区的波束信息，因此可停止通过第二小区上报第一小区的波束信息。
4、终端设备接收来自网络设备的PDCCH命令，或者有效的TA信息，所述PDCCH命令用于触发所述终端设备的随机接入，所述PDCCH命令中包括所述第一小区的波束信息，所述有效的TA信息为在所述终端设备在随机接入过程中，网络设备为所述终端设备分配的。针对该条件可以如此理解，PDCCH命令中会包括网络设备为第一小区分配的用于随机接入的波束，而只有终端设备上报过第一小区的波束信息，网络设备才会为其分配第一小区中用于随机接入的波束。因此，上述PDCCH命令可作为网络设备已接收到第一小区的波束信息的指示。进一步，上述有效的TA信息，是终端设备根据PDCCH命令发起随机接入的过程中，网络设备为其分配的，因此，上述有效的TA信息也可以作为网络设备已接收到第一小区的波束信息的指示。
在一种示例中，第二小区中配置有第一小区的波束上报，当满足上述预设条件时，终端设备可停止利用第二小区上报第一小区的波束信息。而当第一小区变为未激活小区且再次执行激活第一小区时，则终端设备可恢复在第二小区继续上报第一小区的波束信息，且在满足预设条件时，再次停止在第二小区中上报第一小区的波束信息。
在实施例三中，终端设备在第一小区激活过程中，第一小区的PUCCH还不能使用，通过在第二小区中配置待激活第一小区的波束上报，网络设备可以获取第一小区的波束信息，并规定了当第二小区中配置的第一小区的波束上报为周期性波束上报时，终端设备停止上报的条件，以及非周期波束信息上报的第一时间等。
针对实施例三，提供一种具体的示例，该示例至少包括：
1、对于支持CA且支持PUCCH辅小区的终端设备，在添加了PUCCH辅小区后，网络设备发送MAC激活命令激活该PUCCH辅小区。
2、预先在主小区或主辅助小区中配置该待激活的PUCCH辅小区的波束上报。如果配置的是周期性波束上报，则在PUCCH辅小区激活过程中，发生以下事件时，终端设备自动停止在主小区或主辅助小区周期性的上报待激活PUCCH辅小区的波束信息：
1、接收到网络设备发送的待激活小区的TCI，和/或上行空间关系；
2、通过主小区或主辅助小区上报待激活PUCCH辅小区的第一个有效波束信息。例如，该第一个有效波束信息可以为参考信号的L1-RSRP。
3、在待激活的PUCCH辅小区的PUCCH中上报有效的CSI，该有效的CSI代表激活过程完成。
4、收到网络设备发送的PDCCH命令或有效的TA信息等。
或者，如果配置的是非周期波束上报，则终端设备在主小区或主辅小区中利用预配置的资源，上报PUCCH辅小区的波束信息的时间应当不早于，即晚于或等于以下时间：终端设备接收PUCCH辅小区的激活命令的时隙n的时间+第一时间。
通过该实施例三的方案，可以实现PUCCH辅小区的盲添加，在网络设备不知道PUCCH辅小区的波束信息的情况下，终端设备可以通过主小区或主辅助小区上报待激活PUCCH辅小区的波束信息。且在当前的方案中，当在主小区或主辅助小区中配置了波束信息周期性上报时，终设备即便在PUCCH辅小区的激活已经完成，PUCCH辅小区具有通过自己的PUCCH上报波束信息的情况下，也还是占用主小区或主辅助小区的PUCCH资源上报PUCCH辅小区的波束信息。停止在主小区或主辅助小区中上报PUCCH辅小区的波束信息的方案也通常是：通过RRC信令重配，删除在主小区或主辅助小区中配置的PUCCH辅小区的波束上报，这意味着每次PUCCH辅小区激活都需要进行RRC重配，信令开销较大，时延也较大。而在该实施例三中，在PUCCH辅小区的激活过程中，当满足预设条件时，终端设备可认为网络设备已获取PUCCH辅小区的波束信息。此时，终端设备自动停止占用主小区或主辅助小区的PUCCH资源进行上报，终端设备利用自己的PUCCH资源进行上报。相对于通过RRC信令重配，停止在主小区或主辅助小区上报PUCCH辅小区的波束信息的方案，可减少信令开销，缩短时延。而对于在主小区或主辅助主小区配置PUCCH辅小区的非周性上报，对于网络设备来说控制终端设备上报PUCCH辅小区的波束信息的时间是比较困难的。而在该实施例三中，规定了上述第一时间，从而实现网络设备对终端设备通过主小区或主辅助小区上报PUCCH辅小区的波束信息的时间的控制。
