下面对本申请实施例涉及到的一些术语或概念作简单的介绍或描述。
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。因此本申请实施例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。
波束(beam)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。通信设备(包括终端设备和网络设备)通过不同的波束可以发送相同的信息或者不同的信息。可选地，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可以是空域滤波器(spatial filter)。
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 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。
波束质量：可以通过参考信号接收功率(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)，相关性等度量指标度量。应理解，本申请实施例中对波束质量的度量指标不作限 定。
图1是应用本申请实施例的系统100的架构图。如图1所示，该系统100包括：网络设备101和终端设备102。其中，终端设备102中可装备有多个天线面板(panel)(图1中是以终端设备102包括4个天线面板为例示意，但并不对终端设备的天线面板数量构成限定)，可以覆盖不同的方向，每个天线面板可产生一个或多个波束。如果终端设备同时使用多个天线面板，即可实现全方向的发送和接收。可选地，网络设备101中也可以包括多个天线面板。
网络设备101与终端设备102可以采用波束进行数据传输，比如，网络设备101对准一个方向或波束(beam)进行数据发送，终端设备102也需要对准相应的方向或beam接收数据，或者，终端设备102对准一个方向或beam进行数据发送，网络设备101也需要对准相应的方向或beam接收数据。
网络设备101到终端设备102的通信是下行通信，终端设备102到网络设备101的通信是上行通信。根据长期演进LTE/NR的协议，在物理层，上行通信包括上行物理信道和上行信号的传输。其中上行物理信道包括随机接入信道(random access channel，PRACH)，上行控制信道(physical uplink control channel，PUCCH)，上行数据信道(physical uplink shared channel，PUSCH)等，上行信号包括信道探测信号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)等。下行通信包括下行物理信道和下行信号的传输。其中下行物理信道包括广播信道(physical broadcast channel，PBCH)，下行控制信道(physical downlink control channel，PDCCH)，下行数据信道(physical downlink shared channel，PDSCH)等，下行信号包括主同步信号(primary synchronization signal，简称PSS)/辅同步信号(secondary synchronization signal，SSS)，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，相位噪声跟踪信号PTRS，信道状态信息参考信号(channel status information reference signal，CSI-RS)，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。在NR中，下行信道所使用的波束或参考信号发送对应的波束的波束指示是通过关联传输配置指示(transmission configuration indicator，TCI)状态表中的参考资源索引实现的。
需要说明的，图1示出的无线通信系统100仅仅是为了更加清楚的说明本申请的技术方案，并不构成对本申请的限定，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，本申请提供的技术方案对于类似的技术问题，同样适用。
在通信系统中，网络设备相比于终端设备能够更够获得更多信息。为了辅助终端设备更好得管理天线面板，本申请实施例提供了一种管理天线面板的方法，网络设备通过获取终端设备支持的天线面板的能力信息，来决策终端设备激活或者去激活的天线面板。这样，能够避免终端设备由于信息量不足而可能导致的功耗浪费或者通信性能损失等问题。

S220，网络设备向所述终端设备发送第一指示信息，所述第一指示信息用于指示所述终端设备激活和/或去激活一个或多个天线面板。
本申请实施例不限制网络设备向终端设备通知第一指示信息的方法。
第一指示信息可用于指示终端设备激活一个或多个第一天线面板，和/或专用于指示终端设备去激活一个或多个第二天线面板。这里，引入编号“第一”和“第二”是为了便于区分激活和去激活的天线面板，并不对本申请实施例造成限定。
可选地，如果第一指示信息用于指示终端设备激活一个或多个第一天线面板，则所述第一指示信息中会携带终端设备激活所述一个或多个第一天线面板所需要的信息。在这种情况下，第一指示信息可以理解为panel激活命令。可选地，所述第一指示信息可以包括以下中的一项或多项：用于区分该配置是激活panel还是去激活panel的指示信息、panel标识信息、panel激活持续时间、panel激活时间偏移量、panel激活信息、panel激活模式、panel功率控制调整信息、panel时间提前(panel TA)调整信息和panel激活优先级信息等。
其中，panel激活模式可以包括以下情形：

或者，情形四，该工作模式为前述两种工作模式的结合，当终端设备的某一panel进入激活状态后，在一段时间T内，若终端设备没有被网络设备指示使用该panel接收下行信号接收和/或传输上行信号，则该panel可以进入去激活状态。时间长度T可以由网络设备配置、协议约定或能力上报。
或者，情形五，网络设备配置一个计时器时间长度，用于对panel去激活时间进行倒计时。计时器从panel被激活开始进行倒计时，若网络设备指示终端设备使用了该panel传输或接收信号，则计时器重置为网络设备配置的初始值。当计时器归零时，终端设备可以将该panel进行去激活。
可选地，如果第一指示信息用于指示终端设备去激活一个或多个第二天线面板，则所述第一指示信息中会携带终端设备去激活所述一个或多个第二天线面板所需要的信息。在这种情况下，第一指示信息可以理解为panel去激活命令。可选地，所述第一指示信息可以包括以下中的一项或多项：用于区分该配置是激活panel还是去激活panel的指示信息、panel标识信息、panel去激活信息、panel去激活时间偏移量、panel去激活持续时间、panel去激活模式、panel功率控制调整信息、panel时间提前(panel TA)调整信息和panel去激活优先级信息等。

在本申请实施例中，终端设备通过向网络设备发送能力信息，使得网络设备能够得知终端设备所支持的天线面板的能力。网络设备基于所述能力信息，为终端设备选择激活和/或去激活的天线面板，并向终端设备发送第一指示信息，使得终端设备得知网络设备的决策。这样，网络设备参与了天线面板的管理，避免了终端设备在不必要的时候开启了多个天线面板，造成功耗浪费，也避免了可能在需要开启多个天线面板时终端设备没有对天线面板激活，造成通信性能损失，有助于终端设备更好地利用天线面板。
对于步骤S220，可选地，网络设备可以通过高层信令、MAC-CE消息或DCI向终端设备发送第一指示信息，用以指示终端设备对一个或多个的panel进行激活与去激活。
可选地，作为一个实施例，网络设备通过RRC信令发送上述第一指示信息，例如，可以配置一个列表或集合，用于指示panel激活与去激活信息。具体即，网络设备可以在RRC信令中包含激活panel列表，用以指示哪些panel处于激活状态和对应的激活信息，和/或，可以在RRC信令中包含激活去panel列表，用以指示哪些panel处于去激活状态和对应的去激活信息。
可选地，作为一个实施例，网络设备通过MAC-CE消息发送上述第一指示信息，MAC-CE消息中包括以下中的一项或多项：用于区分该配置是激活panel还是去激活panel的指示信息、panel标识信息、panel激活持续时间、panel激活时间偏移量、panel去激活信息、panel去激活时间偏移量、panel去激活持续时间、panel激活模式、panel功率控制调整信息、panel时间提前(panel TA)调整信息和panel激活优先级信息等。

·DCI字段SRS resource indicator指示的所对应的SRS resource set中SRS资源应对应了同一个panel；
·DCI字段SRS resource indicator指示的所对应的SRS resource set中SRS资源的SRS-SpatialRelationInfo中包含的上行参考信号和/或下行参考信号对应了同一个panel；
·DCI字段SRS resource indicator指示的所对应的SRS resource set中SRS资源对应的panel处于激活状态；
·DCI字段SRS resource indicator指示的所对应的SRS resource set中SRS资源对应的panel数量不大于终端设备上报的最大激活panel数量和/或终端设备上报的panel数量的和/或终端设备当前激活的panel数量。
需要统一说明的是，本申请实施例中，天线面板的标识可以通过多种形式体现。例如，网络设备为终端设备的不同panel配置panel ID作为标识。又比如，终端设备可以自行将 不同的panel ID关联到panel上。可选地，天线面板的标识可以以参考信号资源集合标识(和/或同步信号块资源集合标识)体现，例如SRS resource set ID,CSI-RS resource set ID,还可以是参考信号资源标识(和/或同步信号块资源标识)，例如SRS resource ID，CSI-RS resource ID等。当panel标识为参考信号资源或参考信号资源集合的标识时，若该标识为上行参考信号资源(或资源集合)，则该标识对应发送该上行参考信号资源(或资源集合)的UE panel；若该标识为下行参考信号资源和/或同步信号资源，该标识对应接收该下行资源和/或同步信号资源的UE panel。
可选地，所述方法200还包括：
所述网络设备向所述终端设备发送第一资源配置信息，所述第一资源配置信息用于配置一个或多个参考信号资源集合，其中，每个参考信号资源集合与天线面板(比如，panel ID)相关联。
可选地，每个参考信号资源集合与天线面板相关联可以包括以下任一情形：每个参考信号资源集合的标识与天线面板关联；每个参考信号资源集合的标识与天线面板的标识关联；每个参考信号资源集合与天线面板的标识关联，对此不作限定。另外，关联关系可以是一对一，也可以是一对多，对此不作限定。
具体而言，网络设备可以为一个或多个上下行参考信号资源(或资源集)和/或上下行物理信道指示或关联一个或多个panel ID。其中，Panel ID的取值范围可以通过终端设备上报的panel能力信息或其他信息进行确定。例如，对于SRS资源来说，网络设备可以将panel ID与RRC信令中的SRS资源集合(resource set)关联，表示该SRS资源集合内的SRS资源应使用该panel ID所对应的panel发送数据或信号。类似的，网络设备也可以将多个SRS resource set配置为一个SRS resource setting，并为该resource setting关联一个panel ID。
应理解，这里是以每个参考信号资源集合的标识与天线面板的标识相关联为例描述的，实际上，也可以通过参考信号资源集合的标识隐式指示天线面板，不需要引入天线面板的标识的概念，本申请实施例对此不作具体限定。
可选地，网络设备还可以向终端设备发送第二资源配置信息，所述第二资源配置信息用于配置一个或多个载波单元(component carrier，CC)与一个或多个天线面板的关联关系，和/或，所述第二资源配置信息用于配置BWP与一个或多个天线面板的关联关系。也就是说，一个或多个panel可以与一个或多个CC关联，和/或，一个或多个panel可以与一个或多个BWP关联。
对于终端设备而言，例如，当终端设备切换到一个BWP时，终端设备需要激活该BWP对应的panel；当终端设备从该BWP切换到另一个BWP时，终端设备需要去激活切换前的BWP对应的panel。又例如，当终端设备的一个CC激活时，终端设备需要激活该CC对应的panel；当该CC进入去激活状态时，终端设备需要去激活该CC对应的panel。可选地，终端设备应使用与BWP/CC相关联的panel收发该BWP/CC上对应的参考信号或信道。
可选地，网络设备也可以对配置的参考信号资源集合进行激活，那么终端设备需要激活相应的天线面板。比如，网络设备可以对SRS resource set/seting中的部分SRS resource set/seting ID对应的资源集合进行激活，则终端设备需要激活该SRS resource set/seting ID 对应的资源集合对应的panel，即与SRS resource set/seting ID相应数量的panel，或者，发送SRS resource set/seting ID对应的资源所使用的panel。
可选地，网络设备可以将终端设备的一种或多种信道与一个或多个panel进行关联，包括上行控制信道、上行共享信道、下行控制信道、下行共享信道、随机接入信道、物理广播信道、上行参考信号、下行参考信号、同步信号块等中的一种或多种，也可以将一个或多个前述的信道的发送或接收波束与一个或多个panel进行关联。网络设备可以将波束失败检测资源集合、链路失败检测资源集合、波束失败后的候选波束集合、随机接入资源中的一种或多种与一个或多个panel进行关联。
可选地，网络设备可以将终端设备的一个或多个传输配置指示(transmission configuration indicator，TCI)状态关联到一个或多个终端设备的panel。例如，当网络设备通过RRC和/或MAC-CE对终端设备的TCI状态进行配置或激活时，终端设备可以根据配置或激活的TCI状态关联的panel信息对panel进行激活与去激活。可选地，TCI状态与关联关系panel可以通过RRC或MAC-CE进行配置(例如关联表格，或TCI分组)，也可以直接在TCI状态中包含panel索引。一种可能的关联形式如下表1所示：
表1 Panel ID与TCI-ID的关联关系
Panel ID TCI-ID
Panel ID x,Panel ID y TCI-ID a,TCI-ID b
Panel ID z TCI-ID c
Panel ID p,Panel ID q TCI-ID d
Panel ID m TCI-ID e,TCI-ID f
从表1中可知，Panel ID x,Panel ID y可以与TCI-ID a,TCI-ID b关联；Panel ID z可以与TCI-ID c关联；Panel ID p，Panel ID q可以与TCI-ID d同时关联；Panel ID m可以与TCI-ID e和TCI-ID f同时关联。上述关联关系对于panel ID和/或TCI-ID的数量不做限定，即panel ID与TCI-ID可以一一关联、多对一关联、一对多关联或多对多关联。
应理解，这里只是以表1中的关联关系为例进行说明，并不对本申请实施例构成限定。
类似的，网络设备可以通过配置SRS的空间关系指示该SRS对应的panel。例如，网络设备可以在SRS resource的波束指示SRS-SpatialRelationInfo中或SRS resource的RRC配置中包含一个或多个panel ID，以指示发送该SRS和/或发送该SRS所指示的PUSCH对应的panel。可选地，网络设备可以在用于码本和/或非码本传输的SRS resource set中配置一个panel数量，以指示发送该SRS和/或发送该SRS所指示的PUSCH时应使用的panel数量。
可选地，网络设备通过配置或约定规则为各个panel设定不同的优先级(例如panel ID大小对应相应的优先级高低次序)。网络设备的第一指示信息中可以不包含具体的panel ID，终端设备按照自主选择或按照优先级排序激活或去激活不同的panel。网络设备也可以在第一指示信息中指示需要激活/去激活的panel数量，终端设备按照自主选择或按照优先级排序激活或去激活指定数量的不同panel。网络设备也可以在激活或去激活命令中指示当前需要保持激活状态的panel数量，终端设备按照自主选择或按照优先级排序保持激 活指定数量的不同panel，并可以去激活剩余panel。可选地，可以通过网络设备配置或协议约定的方式设置一个默认panel(例如初始接入的panel或特定panel ID对应的panel)，当终端设备没有被指示发送或接收某一参考信号资源或信道的panel时，终端设备应使用默认panel收发该参考信号资源或信道。
在本申请实施例中，终端设备还可以获取激活天线面板的时序信息和/或去激活天线面板的时序信息，下面将具体描述。终端设备收到用于指示激活或去激活panel#a的命令的时刻N有以下几种可能定义方式：若激活/去激活命令为MAC CE消息，时刻N是终端设备发送该MAC-CE消息对应的ACK/NACK的时隙(或最后一个OFDM符号、子帧、帧等)，若激活/去激活命令为DCI触发，则时刻N为该DCI所在PDCCH的最后一个OFDM符号(或时隙、子帧、帧等)。应理解，这些时序信息可以是协议预定好的，也可以是网络设备配置给终端设备的，也可以是终端根据自身能力上报的值，对此不作具体限定。还应理解，这些时序信息中包括时间(比如下文中出现的第一时间、第二时间、第三时间或第四时间，或其他表示时间的字母或数值)，时间可以是绝对时间长度，也可以是相对时间长度，对此不作限定。可选地，时间的单位可以是符号、子帧、时隙、微时隙、毫秒、秒等时间度量单位，应理解，这里只是示例性地列出时间的单位，并非是将本申请实施例限定于此，本领域技术人员可以得知其他时间度量单位，均适应于本申请实施例。
假设终端设备在时刻N收到第一指示信息，该第一指示信息用于指示终端设备激活一个或多个第一天线面板。下面描述所述终端设备根据的相关时序信息的进行相关panel激活操作的时序行为。可选地，所述方法200还包括：
所述终端设备获取第一时间信息，所述第一时间信息用于指示所述终端设备需要在第一时间结束后需要保持所述一个或多个第一天线面板处于激活状态。
可选地，所述第一时间信息可以是网络设备发送给终端设备的，也可以是协议约定好的。其中，若所述第一时间信息是网络设备发送给终端设备的，所述第一时间信息可以携带于第一指示信息中，也可以是网络设备单独下发给终端设备的，对此不作限定。
终端设备获取到所述第一时间信息后，在收到网络设备的激活命令(即所述第一指示信息)时，在第一时间后需要使用激活后的天线面板进行信号的发送和/或接收。为实现上述行为，终端设备需要在第一时间内将激活命令指示的天线面板成功激活。
可选地，一种实施方式为，可选地，若在第一时间结束前第一天线面板已是激活状态，则终端设备继续保持第一天线面板的激活状态即可；若第一天线面板不是激活状态，则终端设备在第一时间结束后执行激活操作，激活该第一天线面板。也就是说，若第一天线面板不是激活状态，则终端设备在等待第一时间后对天线面板进行激活。
举例来说，终端设备在收到用于指示激活panel#a对应的panel激活命令，且激活命令中携带生效时间为T1。生效时间T1可以理解为：当终端设备在时刻N收到激活命令，则在N+T1时刻，panel#a需为激活状态。终端设备需要在时间T1内将panel#a变为激活状态，使用panel#a进行信号的传输和/或接收。
可选地，另一种实施方式为，第一时间信息用于指示所述终端设备可以在等待第一时间后对所述一个或多个第一天线面板执行激活操作。换言之，所述终端设备获取第一时间信息后，在所述第一时间信息结束后需要激活所述一个或多个第一天线面板。
可选地，终端设备在激活天线面板后，可以在一段时间内维持天线面板的激活状态。 具体即，所述方法200还包括：
所述终端设备获取用于指示维持所述一个或多个第一天线面板激活的时长(可以简称激活时长)；
所述终端设备在将所述一个或多个第一天线面板激活的情况下，在所述时长内维持所述一个或多个第一天线面板的激活状态。
可选地，所述激活时长可以是网络设备发送给终端设备的，或者，也可以是协议约定好的。其中，若所述激活时长是网络设备发送给终端设备的，所述激活时长可以携带于第一指示信息中，也可以是网络设备单独下发给终端设备的，对此不作限定。
可选地，所述激活时长可以通过计时器实现。举例来说，终端设备在激活panel#a对应的panel后，可以为该激活的panel维持一个计时器或有效时间窗。当该激活的panel进入激活状态时，计时器开始计时，当计时器到达激活时长后(即逾期状态)，该激活的panel进入去激活状态。
可选地，如果终端设备在使用panel#a发送信号和/或接收信号时，则该计时器重新开始计时。可选地，信号可以是以下信号中的一项或多项：上行控制信道、上行共享信道、随机接入信道、下行控制信道、下行共享信道、物理广播信道、上行参考信号、下行参考信号、同步信号、精同步信号(CSI-RS for tracking,TRS)等。或者，终端设备可以在计时器逾期之前，优先使用panel#a发送信号和/或接收信号。
可选地，终端设备在上述计时器逾期后，可以切换到默认panel。默认panel可以是网络设备可以为终端设备指定的。例如，默认panel可以是panel ID最小的panel、panel ID为0的panel、初始接入时使用的panel、上一个激活的panel。或者，终端设备在上述计时器逾期后，可以进入DRX和/或DRT状态。Panel#a将按照一定的周期进入激活与去激活状态。
当终端设备收到panel激活命令且激活状态的panel数超过终端设备上报的最大激活panel数时，终端设备在当前激活的panel中选择最先激活的panel进行去激活。
所述激活时长的起点可以是收到激活命令的时刻N，也可以是第一时间的终止点。
假设终端设备在时刻N收到第一指示信息，该指示信息用于指示终端设备激活一个或多个第二天线面板。下面描述所述终端设备根据的相关时序信息的进行相关panel激活操作的时序行为。可选地，所述方法200还包括：
终端设备获取第二时间信息，所述第二时间信息用于指示所述终端设备在第二时间后能够去激活所述一个或多个第二天线面板。
终端设备在收到所述第一指示信息后，在等待第二时间后才开始对所述一个或多个第二天线面板执行去激活操作。也就是说，终端设备在时刻N收到一个或多个第二天线面板的去激活指令后，若第二时间是T4，则在N+T4时刻后可以对所述一个或多个第二天线面板进行去激活。
可选地，所述第二时间信息可以是网络设备发送给终端设备的，或者，也可以是协议约定好的。其中，若所述第二时间信息是网络设备发送给终端设备的，所述第二时间信息可以携带于第一指示信息中，也可以是网络设备单独下发给终端设备的，对此不作限定。
终端设备获取到所述第二时间信息后，在收到了网络设备的去激活命令(即所述第一指示信息)时，可以等待第二时间后才对去激活命令指示的天线面板进行去激活操作。
可选地，所述方法200还包括：
所述终端设备获取用于指示维持所述一个或多个第二天线面板去激活的时长(可以简称为去激活时长)，所述去激活时长用于指示所述终端设备在将所述一个或多个第二天线面板去激活的情况下可以在去激活时长内维持所述一个或多个第二天线面板的去激活状态。
可选地，所述去激活时长可以是网络设备发送给终端设备的，或者，也可以是协议约定好的。其中，若所述去激活时长是网络设备发送给终端设备的，所述去激活时长可以携带于第一指示信息中，也可以是网络设备单独下发给终端设备的，对此不作限定。
终端设备获取到所述去激活时长后，在将一个或多个第二天线面板去激活的情况下，在去激活时长内维持该一个或多个第二天线面板的去激活状态。
可选地，所述去激活时长可以通过计时器实现。举例来说，终端设备在去激活panel#a对应的panel后，可以为该激活的panel维持一个计时器或有效时间窗。当该激活的panel进入去激活状态时，计时器开始计时，当计时器到达去激活时长后(即逾期状态)，终端设备可以切换到默认panel，或重新激活panel#a。
去激活时长的起点可以是收到去激活命令的时刻N，也可以是第二时间的终止点，对此不作限定。
可选地，上述时序流程还可以应用于panel切换或panel关联指示，panel关联或panel关联指示的切换和生效可以视为一个激活行为。例如，网络设备可以通过指示信息指示终端设备将参考信号资源或物理信道的panel关联关系从原来的panel#a替换为panel#b。切换后的关联关系的生效可以等效为panel#b的激活流程，具体即：
终端设备获取到第三时间信息后，在收到网络设备的切换关联关系命令(例如MAC-CE消息)时，在第三时间后需要使用切换后的天线面板(本例panel#b)进行信号的发送和/或接收。
可选地，另一种实施方式为，在收到网络设备的切换关联关系命令(例如MAC-CE消息)时，可以等待第三时间后才对切换命令指示的天线面板进行切换(使用panel#b收发对应的信号/信道)。
可选地，终端设备获取到第四时间信息后，在天线面板切换后，在第四时间内维持所指示的关联关系(本例中，维持panel#b与所述信号/信道关联)。在第四时间后，可以切换回原panel(panel#a)或默认panel。
应理解，本申请实施例引入“第一”、第二、第三、第四，只是为了区分不同的对象，比如，“第一时间信息”、“第二时间信息”、“第三时间信息”、“第四时间信息”只是为了区分不同的时间信息，或者，“第一时间”、“第二时间”、“第三时间”、“第四时间”只是为了区分不同的时间信息，并非要限定时间上的先后顺序。
本申请还提供了一种实施例，网络设备可以为终端设备的panel配置功率控制信息。需要说明的是，该实施例可以单独实施，也可以与前文的实施例(比如方法200)和/或后文的实施例组合实施，对此不作限定。
在本申请实施例中，终端设备还可以获取天线面板的功率控制的相关信息。可选地，网络设备针对不同的panel，为终端设备配置独立的功率控制环。相应地，终端设备可以不考虑panel切换对于功率控制的影响，当终端设备收到激活panel的命令或者切换panel 的命令后，当前活动panel的功率控制状态可以直接应用到新激活的panel。或者，可选地，网络设备可以将终端设备的panel进行分组，为不同的分组配置不同的功率控制环。相应地，对于同一个分组内的panel，终端设备应维护一个公共的功率控制环，即分组内的panel共享一套功率控制参数与状态；对于不同的panel分组，终端设备可以使用不同的功率控制环。
可选地，网络设备可以为每个panel配置一个独立的功控参数。这里以上行共享信道PUSCH为例，网络设备可以通过RRC信令和DCI配置PUSCH的发射功率计算公式中的参数值。上行功率控制的参数配置可以包含多个RRC信息元素(information element，IE):PUSCH-ConfigCommon和PUSCH-PowerControl等。功率参数的配置可包括开环功率参数(例如p0,p0-NominalWithGrant,p0-NominalWithoutGrant等)，闭环功率参数，其他功率参数(路损补偿参数alpha，MCS的功率调整判断deltaMCS，功率积累形式tpc-Accumulation等)。如下表2和表3所示，其中列出了几个与PUSCH相关的功控控制参数：

其中，δ PUSCH,b,f,c(i last,i,K PUSCH,l)为一个修正值，又称为TPC命令(TPC command)，包含在载波c的BWP b最近一次PUSCH occasion i last之后的调度PUSCH occasion i的DCI格式0_0或DCI format 0_1，或在TPC-PUSCH-RNTI加扰CRC校验位的DCI format 2_2中与其他TPC命令联合编码。f b,f,c(i,l)和δ PUSCH,b,f,c(i last,i,K PUSCH,l)可以统一称为闭环功率调整量。根据累计量是否为使能状态，TPC命令(可选地，TPC命令可以是两比特(bit))与对应功率调整量的映射关系如下表4所示。其中，第一列为TPC命令，第二列是在功率积累使能状态下，TPC命令对应的功率调整量；第三列为功率积累去使能状态下，TPC命令对应的功率调整量。

可选地，当终端设备收到第一指示信息(panel切换命令、panel激活命令或者panel去激活命令)是，将闭环功率调整量f b,f,c(i,l)和/或δ PUSCH,b,f,c(i last,i,K PUSCH,l)置为0。当终端设备在切换panel状态时，如果终端设备维护了δ PUSCH,b,f,c(i last,i,K PUSCH,l)的积累量，可以将积累量应保持并应用于panel之后的PUSCH，或者，也可以将δ PUSCH,b,f,c(i last,i,K PUSCH,l)重置为0。
可选地，在本申请实施例中，可以采用下述公式(2)计算每个panel对应的发射功率：
Figure PCTCN2019099646-appb-000007
相比于发射功率的计算公式(1)，上式(2)中引入n，其中，n为panel的索引标识， 即在计算发射功率时考虑panel的因素。在本申请实施例中，终端设备可为不同panel维护不同的闭环功率调整量，例如f b,f,c,n(i,l)和/或δ PUSCH,b,f,c,n(i last,i,K PUSCH,l)。这种情况下，终端设备在切换panel后，应使用切换后的panel所对应的功率控制参数。
需要说明的是，上述公式(2)中不一定所有项都同时与n有关。例如，每个panel可以维护自己的功率积累量，但是其余参数与panel索引无关。一种可能的情况为，终端设备接收到的panel激活命令中包含了上述功率控制参数。同时，网络设备可以通过配置信息或协议约定等方式告知终端设备，panel功率控制信息是针对所有panel或部分panel或单个panel独立配置。或者，网络设备可以告知终端设备当前激活的panel应当沿用其他某一panel的功率控制状态。另外，终端设备接收到的panel去激活命令中也可以额外指示终端设备是否清空或保存当前panel的功率控制参数状态。
可选地，作为一个实施例，网络设备可以为终端设备配置功率控制参数的生效时间。具体而言，网络设备可以为每个panel或panel分组配置生效时间，在该生效时间内，网络设备为每个panel或panel分组配置的功率控制参数一直有效(即使panel从激活状态被去激活)，直到生效时间到期。在生效时间到期后，可以清空功率控制参数的状态。
可选地，作为一个实施例，网络设备还可以为每个panel的每个波束配置独立的功控参数。可选地，每个波束独立的功控参数可以是相对于其所属panel的功控参数的偏移值。当终端设备使用该波束发送信号时，其发送功率由panel的功控参数和波束的功控参数共同决定。
可选地，网络设备通知终端功控参数的方法可以通过广播信道，RRC信令，MAC-CE信令，控制信令DCI中的一种或多种的组合。
可选地，当网络设备需要终端同时使用多个panel时，网络设备通过广播信道，RRC信令，MAC-CE信令，控制信令DCI中的一种或多种的组合通知终端多个panel的功控参数。
可选地，当网络设备需要终端同时使用一个panel的多个波束时，网络设备通过广播信道，RRC信令，MAC-CE信令，控制信令DCI中的一种或多种的组合通知终端一个panel的多个波束的功控参数。
可选地，当网络设备需要终端同时使用多个panel的多个波束时，网络设备通过广播信道，RRC信令，MAC-CE信令，控制信令DCI中的一种或多种的组合通知终端多个panel的多个波束的功控参数。
可选地，网络设备可以通过MAC-CE信令通知panel的TA偏移值，通过DCI通知相对于该panel的波束的功控参数。
本申请还提供了一种实施例，网络设备可以为终端设备的panel配置相关的时间提前量信息。需要说明的是，该实施例可以单独实施，也可以与前文的实施例(比如方法200)组合实施，对此不作限定。下面将具体介绍。
网络设备向终端设备发送天线面板的时间提前量信息，所述时间提前量信息中包括时间提前量TA，所述天线面板是所述网络设备指示的需要激活或者去激活的一个或多个天线面板中的任一个。
可选地，所述时间提前量信息也可以携带于前文第一指示信息中。
可选地，所述时间提前量信息可以携带于MAC CE消息、随机接入相应RAR或DCI 等其他信息。
具体而言，网络设备可以为终端设备的每个天线面板单独配置时间提前量。或者，网络设备可以为一个天线面板组(panel group)配置同一个时间提前量。类似的，网络设备可以为终端设备的每一个上行波束指示(例如SRS或者SRS resource set)配置时间提前量。
可选地，网络设备通过高层信令为终端设备配置一个或多个时间提前panel组(Timing advance panel group)。每个panel group中包含或者关联一个或多个panel，且对应一个panel group ID(PG-ID)，终端设备针对每个panel group维护一个TA量。
或者，可选地，网络设备将panel或者panel group关联到一个时间提前量组(Timing advance group，TAG)，终端设备针对每个TAG维护一个TA量。
或者，可选地，网络设备将panel或者panel group关联到多个TAG，终端设备针对每个TAG维护一个TA量，对于不同的TAG，同一个panel可以有不同的TA量。
应理解，这里统一进行说明，本申请实施例中的TA量可以是N TA，也可以是绝对TA值，本申请实施例对此不作限定。
可选地，所述时间提前量信息中还可以包括以下信息中的一项或多项：panel group ID、panel ID或者TAG ID、时间提前量调整信息。其中，时间提前量调整信息可以是针对一个panel或panel group的时间提前量调整信息，也可以是针对关联了某一个或多个TAG的一个或多个Panel的时间提前量调整信息，或关联了某一个或多个panel的一个或多个TAG的时间提前量调整信息。

可选地，时间提前量调整信息中携带时间提前调整量。对应地，终端设备在第n个时隙slot收到时间提前量调整信息后，应当在第n+T apply个时隙应用该时间提前调整量。T apply可以由网络设备通过控制信息配置，也可以协议约定方式计算。本申请实施例中的时间提前调整量，可以是一个绝对调整量，即终端设备可以使用该绝对调整量直接替换掉现有的时间提前量；或者，也可以是一个相对调整量，即该相对调整量表示终端设备在现有的时间提前量的基础上使用该相对调整量进行增或减操作。可选地，本申请实施例中的时间提前调整量可以经过量化，量化分辨率可以与子载波间隔相关。
可选地，本申请实施例的时间提前量相比于现有技术的计算方式，可以增加时间提前参数T offset,panel，其中，该时间提前参数可以通过网络设备配置或协议约定，可以跟上下行发送是否切换panel或panel group相关，也可以由panel或panel group开启状态确定。 具体地，本申请实施例的时间提前量可采用下面公式(3)计算：
T TA＝(N TA+N TA,offset+T offset,panel)T c                        (3)
其中，N TA为一个经过了量化的时间提前参数，通过N TA可以计算该N TA对应的上行子帧相对于同步的下行子帧i的时间提前量；T c＝1/(Δf max·N f)，Δf max＝480·10 3Hz，N f＝4096；N TA,offset为一个跟频带相关的量，也可能通过高层信令进行指定，其取值可参见下表5所示：

上述表5中涉及到的概念或含义可参见现有标准协议TS 38.133(NR；Requirements for support of radio resource management)中的描述，为了简洁，这里不作赘述。
可选地，如果一个panel group包含多个panel，为了实现更精准的TA控制，可以引入两级TA的方法，先配置一个基准的panel group级的TA或者TA offset，在此基础上为每一个panel配置相对于panel group的TA或者TA offset，具体地，本申请实施例的时间提前量可采用下面公式(4)计算：
TTA，panel＝(NTA+NTA,offset+Toffset,panelgroup+Toffset,panel)Tc       (4)
其中，公式(4)中的TTA，panel是每个panel应该应用的TA，Toffset,panelgroup是每个panel group相对于基准值(即NTA+NTA,offset)的TA偏移值。Toffset,panel是每个panel相对于panel group的TA偏移值。如果没有panel group，上述公式(4)简化为公式(5)：
TTA，panel＝(NTA+NTA,offset+Toffset,panel)Tc           (5)
如果panel group内的panel数目为1，上述公式(4)简化为公式(6)：
TTA，panel＝(NTA+NTA,offset+Toffset,panelgroup)Tc             (6)
可选地，如果一个panel能发送一个或多个可能的波束，为了实现更精准的TA控制，还可以引入波束级的TA或者TA offset，每个波束的TA offset是相对于其所在panel的TA值，具体的，本申请实施例的时间提前量可采用下面公式(7)计算：
TTA，beam＝(NTA+NTA,offset+Toffset,panel+Toffset,beam)Tc        (7)
其中TTA，beam是每个beam应该应用的TA，Toffset,beam是每个beam相对于panel的TA偏移值。
可选地，如果有panel group而只有panel，上述公式(7)可以变更为公式(8)：
TTA，beam＝(NTA+NTA,offset+Toffset,panelgroup+Toffset,panel+Toffset,beam)Tc(8)
可选地，上述公式中的TA偏移值都可以预定义或由网络设备通知终端，所述TA偏移值包括至少以下一种：每个panel group相对于基准值(即NTA+NTA,offset)的TA偏移值，每个panel相对于基准值(即NTA+NTA,offset)的TA偏移值，每个panel相对于其所在的panel group的TA偏移值，每个beam相对于其所在的panel的TA偏移值，每个beam相对于基准值(即NTA+NTA,offset)的TA偏移值。
