  • the terminal since the terminal includes multiple panels, it takes a certain time for a panel to activate from the sleep state to the operable mode, so the terminal needs to determine how many panels are activated and which panels are activated when entering the ON state; activating all panels can provide the highest reliability Performance, but it will also bring the highest power consumption.
  • There may be reliability problems when activating a panel For example: the panel does not have a suitable beam to communicate with the base station.

Description

一种天线面板及波束的管理方法和设备 技术领域
本申请涉及通信领域，并且更具体地，涉及终端设备中面板、波束管理方法和设备。
背景技术
在现有的无线通信网络(如2G、3G和4G网络)中，通信系统的工作频段都在6GHz以下的频率范围中，而在这个频率范围内可用的工作频段越来越少，无法满足日益增长的通信需求。相反，6GHz以上的频率范围却有大量未充分利用的频段。因此，业界正在研究和开发工作频段在6GHz以上的下一代(如5G)无线通信网络，以提供超高速的数据通信业务。在6GHz以上的频率范围，可用于下一代无线通信网络的频段包括位于28GHz、39GHz、60GHz、73GHz等处的频段。因其工作频段在6GHz以上，下一代无线通信网络具有高频通信系统的显著特点，如大带宽和高集成天线阵列，从而容易实现到较高的吞吐量。
终端使用高频通信，可以装备多个天线面板，简称面板(panel)，以覆盖多个不同的方向。终端每一个panel朝向一个方向，发送一个或多个波束；使用多个panel时，分别发送覆盖不同的方向的波束，即可实现全方向波束的发送和接收。
非连续接收(Discontinuous Reception，DRX),包括连接态的非连续接收(Connected Mode DRX，CDRX)等，是终端节能的一种技术，简单来说就是为终端配置睡眠模式(sleep mode)和醒来模式(wake up mode)，以及它们各自的时间长度；终端在睡眠模式无需监听网络发送的数据，从而实现节能的目的。
在基于波束的高频通信中，在终端进入休眠状态后，可能由于移动，旋转，遮挡，信道变化等原因失去了与基站的波束对齐，在终端醒来时，需要快速的找到能与基站通信的波束。
但是，由于终端使用了多个panel，每个panel用于接收或发送不同方向的波束，如何激活合适的panel，从而选择合适的波束与基站通信是目前需要解决的问题。
发明内容
本申请提供了一种天线面板的管理方法，终端设备可以激活合适的panel，进一步的，降低终端设备的功耗。
第一方面，公开了一种天线面板管理的方法，所述方法包括：终端设备从激活状态进入休眠状态；当所述终端设备从所述休眠状态准备再次进入激活状态时，如果休眠时间小于预设的门限，则激活所述终端设备的单个面板(panel)：或如果休眠时间大于或等于预设的门限，则激活所述终端设备的多个panel。
结合上述方案，进一步包括：如果休眠时间小于预设的门限，则使用所述激活的单个panel进行波束训练：或如果休眠时间大于或等于预设的门限，则使用所述激活的多个panel进行波束训练。 波束训练后，便可以找到合适的波束与基站通信。波束训练也可以称为波束扫描、波束对准或波束管理。
结合上述方案，进一步包括：终端设备根据网络设备预先下发的波束管理资源或波束管理资源集合的配置进行波束训练。如果休眠时间小于预设的门限，则网络设备下发单个panel的波束管理资源；如果休眠时间大于或等于预设的门限，则网络设备下发多个panel的波束管理资源。
结合上述方案，所述终端设备的单个panel为上一次使用的panel，所述终端设备的多个panel为全部panel。上一次使用的panel也就是最近一次使用的panel，可以为上次激活状态与基站通信使用的panel，也可以基站配置或激活的panel。

结合上述方案，激活是开启的意思，在另一个例子中，单个panel可以为少部分panel，其中包括上一次使用的panel即可；多个panel可以为大部分panel，其中包括上一次使用的panel。
上述方案中，终端设备根据两次激活状态之间休眠时间的长短进行panel的激活，便于及时打开合适的panel，并进一步的找到合适的波束与基站通信；如果休眠时间很短，则认为终端设备的位置没有发生变化，可以直接使用上一次使用的panel即可，节省了终端设备的功耗。
在其他的实现方式中，上述最近一次使用的panel也可以用预先设定的panel来替换，预先设定的panel可以为以下一个或多个：Panel标识最低和/或最高的panel；接收和/或发送低频信号使用的panel；天线单元数目最多和/或最少的panel；发送功率最高和/或最低的panel。

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终端设备自身使用的接收波束为接收波束#1，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，下面对本申请中涉及的几个术语做简单介绍。
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。波束成形技术具体可以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。
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。
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。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参考信号接收功率(reference signal receiving power，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)，块误码率(block error rate，BLER)，信号质量指示(channel quality indicator，CQI)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。
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)。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、SRS资源(SRS resource)。
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)。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。
波束指示信息：用于指示传输所使用的波束的信息。包括发送波束和/或接收波束。波束指示信息可以是下述中一种或多种：波束号(或者说编号、索引(index)、标识(identity，ID)等)、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。其中，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。
波束指示信息还可以体现为传输配置编号(Transmission Configuration Index，TCI)或者TCI状态。一个TCI状态包括一个或多个准共址(quasi-co-location，QCL)信息，每一个QCL信息包括一个参考信号(或同步信号块)的ID和一种QCL类型。例如：终端设备可以需要根据网络设备指示的TCI状态(通常由物理下行控制信道(physical downlink control channel，PDCCH)携带)来确定接收物理下行共享信道(physical downlink shared channel，PDSCH)的波束。
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)，层一信号与干扰噪声比(layer 1 signal to interference plus noise ratio，L1-SINR)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。
准共址(quasi-co-location，QCL)：或者称准同位。准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。具体的。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(也可以称为QCL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，所述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。
空域准同位(spatial QCL)：spatial QCL可以认为是QCL的一种类型。对于spatial，可以分别从发送端或接收端角度进行理解：从发送端来看，如果两个天线端口是空域准同位的，即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，如果两个天线端口是空域准同位的，则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)：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。
同时接收：本发明所提到的同时接收包括接收端(例如UE)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。
模拟波束成型，可以通过射频实现。例如，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RF chain在同一时刻只能打出一个模拟波束。
DRX是终端的一种节能技术，简单来说就是为终端配置休眠模式(sleep mode)和激活模式(active mode)，以及它们各自的时间长度。终端在激活模式监听网络发送的数据，休眠模式无需监听网络发送的数据，从而实现节能的目的。
DRX包括长DRX和短DRX，以下结合图2介绍DRX中的一些术语：
drx-LongCycle:the duration at the beginning of a DRX Cycle；一个长DRX周期的时间长度。
drx-onDurationTimer:the duration at the beginning of a DRX Cycle；在一个DRX周期开始时，终端保持ON状态时间长度。ON状态也称为激活(Active)状态，可以用DRX ON表示；DRX ON状态意味着终端功耗高，因为其需要监测控制信道，进行参考信号测量等。
drx-InactivityTimer:the duration after the PDCCH occasion in which a PDCCH indicates a new UL or DL transmission for the MAC entity；UE在接收到一个PDCCH后，继续保持ON状态时间长度。这个PDCCH是指示了上行(UL)或者下行(DL)传输的PDCCH。这是因为接收该PDCCH后，后续会有数据的发送或接收，因此，即使原计划的DRX ON状态时间(drx-onDurationTimer)到了，终端还是应该继续保持DRX ON状态，完成数据的发送或接收。
drx-ShortCycle:the Short DRX cycle；一个短DRX周期的时间长度。
drx-ShortCycleTimer:the duration the UE shall follow the Short DRX cycle；终端使用短DRX周期模式的时间长度。例如，可以为一个短DRX周期(drx-ShortCycle)时间长度，也可以为多个drx-ShortCycle时间长度等。
其中：短DRX如果没有配置，则可以仅使用长DRX的配置。
例如：图2中，终端处于长DRX中的ON duration，即激活状态，则需要监控PDCCH，如果没有数据传输，则在drx-onDurationTimer到期后进入休眠状态；下一个长DRX中，终端进入ON状态，如果某个时隙接收到PDCCH，例如第二个时隙接收到，则启动drx-InactivityTimer，如果有数据传输，即使原计划的ON duration时间到了，终端还是应该继续保持ON状态，完成数据的发送或接收。然后再进入休眠态和下一个DRX周期。
在基于波束的高频通信中，在终端进入休眠状态后，可能由于移动，旋转，遮挡，信道变化等原因失去了与原基站的波束对齐，在终端重新进入DRX ON状态时，终端需要快速的进行找到能与基站通信的波束。
另外，由于终端包括多个panel，一个panel从休眠状态激活到可工作模式需要一定的转换时间， 因此终端需要确定在进入ON状态时激活多少panel和激活哪些panel；激活所有panel可以提供最高的可靠性，但是也会带来最高的功耗，激活一个panel则有可能会出现可靠性问题，例如：该panel没有合适的波束与基站通信，因此，很难准确确定具体激活哪个panel；如果选错了需要激活的panel，终端可能无法与基站进行波束通信。
本申请实施例提供了一种终端设备中天线面板管理的方法，终端设备可以根据DRX中休眠时间长短确定panel的激活；如果休眠时间长则激活多个或全部panel，进而进行波束训练，休眠时间短则只需要激活单个或部分panel，进而进行波束训练。
通过上述方式，尽量保证终端设备激活合适数量的panel，并且减少了终端设备的功耗，下面将结合附图详细说明本申请实施例。
图3是从设备交互的角度示出的天线面板管理方法流程图。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主体为例，对指示波束信息的方法进行说明。作为示例而非限定，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。以下以终端设备是UE为例，网络设备是基站为例进行说明：
S100：UE能力上报(UE capability transfer)。
UE将能力上报给基站；UE可以主动上报其能力，基站也可以发起UE能力请求，UE收到该请求后向网络上报其相关能力。
UE能力发生变化时，可以将更新的UE能力传递给基站；例如：UE可以向基站发送用于指示UE能力发生变化的请求，基站收到该请求后，为UE配置上行资源，然后UE使用该上行资源将更新的UE能力传递给基站。
例如，UE能力可以包括以下一种或多种：
UE的接收panel数目：{例如1-8}，{1-8}是指UE可以上报1-8中的一个整数，例如4，代表UE有4个接收panel，上述数字范围仅仅是举例，不限于上述数量，下同。
UE的发送panel数目：{例如1-8}；
一个panel可以既是发送panel，又是接收panel，也可以只用于发送或只用于接收。
UE能同时使用的接收panel数目：{例如1-8}
UE能同时使用的发送panel数目：{例如1-8}
UE每个接收panel能接收的beam数目：{例如1-16}
UE每个发送panel能发送的beam数目：{例如1-16}
UE切换接收panel的能力，可以包括以下一种或多种：
从关闭状态到开启panel的时间，例如{0,2,3}毫秒(ms)等；
接收panel切换的时间，例如{0,0.5,1}毫秒(ms)等；
一定时间内接收panel切换次数，例如一个时隙内UE最多能进行{1,2,4,7,14次}切换panel切换；
UE切换发送panel的能力，也可以包括以下一种或多种：
从关闭状态到开启panel的时间，例如{0,2,3}毫秒(ms)等；
发送panel切换的时间，例如{0,0.5,1}毫秒(ms)等；
一定时间内接收panel切换次数，例如一个时隙内UE最多能进行(1,2,4,7,14次)切换panel切换。
基站收到UE上报的能力后，进行网络配置可以考虑该能力，不进行超出UE能力的配置。
S101：基站发送配置信息给UE。
本实施例涉及的配置信息包括：DRX配置，可以参考上述DRX的介绍，不再详述。
还可以进一步包括波束管理资源配置，可以包括：
上行波束管理资源，例如：SRS资源和/或SRS资源集合的配置，还可以进一步包括SRS资源设置的配置；
下行波束管理资源，例如：CSI-RS资源和/或CSI-RS资源集合，还可以进一步包括CSI-RS资源设置的配置；
S102：UE在DRX ON状态与基站正常通信。
正常通信例如：监测PDCCH，测量CSI-RS和上报，发送SRS，发送上行PUCCH，传输PDSCH或PUSCH等。
S103：UE进入休眠状态。
UE按照DRX配置进入休眠状态，例如，UE不再监测PDCCH。
S104：UE准备进入DRX ON状态；UE根据休眠时间长短，确定激活的panel。
例如：如果休眠时间小于或等于(或小于)预设时间长度门限，UE只开启单panel，例如最近一次使用过的panel，也可以为预先设定的panel；如果休眠时间大于(或大于或等于)预设时间长度门限，则UE开启多个panel，也可以为全部panel。
最近一次使用的panel可以包括以下一项或多项：
最近一次使用的接收PDCCH/PDSCH/CSI-RS的panel；
最近一次配置或激活的接收PDCCH/PDSCH/CSI-RS的panel；
最近一次使用的发送PUCCH/PUSCH/SRS/RACH的panel；
最近一次配置或激活的发送PUCCH/PUSCH/SRS/RACH的panel；
预先设定的panel包括以下一项或多项：
Panel id最低/最高的panel；
接收/发送低频信号使用的panel；
天线单元数目最多/最少的panel；
发送功率最高/最低的panel；
休眠时间的长度是UE在两次DRX ON状态之间的时间长度，上述时间长度门限可以是一个设定值，如果休眠时间很短，则可以认为终端位置基本没有发生变化，因此可以继续采用上次使用的panel，或预先设定的panel；如果休眠时间比较长，则认为终端位置发生变化，上次使用的panel已经不合适，因此需要打开多个或全部的panel，才能找到合适的波束。上次使用的panel可以是上次在DRX ON状态与基站通信的panel。
在另一个例子中，也可以采用如下方式：
如果休眠时间小于或等于(或小于)预设时间长度门限，UE开启部分panel，其中包括最近一次使用过的panel或预先设定的panel。如果休眠时间大于(或大于或等于)预设时间长度门限，则UE开启全部panel。
上述例子中，部分panel可以是少部分panel，全部panel也可以为大多数panel。
休眠时间长短与以下一个或多个参数相关：
DRX周期的长短，例如drx-LongCycle，drx-ShortCycle；
在每个DRX周期保持激活状态的时间，例如drx-onDurationTimer；
收到PDCCH后延长激活状态的时间，例如drx-InactivityTimer；
考虑重传延长激活状态的时间，例如drx-RetransmissionTimerDL，drx-RetransmissionTimerUL；
休眠时间长短可以由DRX周期的长短来判断；例如，如果UE工作在短DRX周期模式，则认为休眠时间短，应该使用单panel；如果UE工作在长DRX周期模式，则认为休眠时间长，应该使用多panel。或者，如果DRX周期小于或等于(或小于)预设DRX周期时间长度门限，则认为休眠时间短，应该使用单panel；如果DRX周期大于或等于(或大于)预设DRX周期时间长度门限，则认为休眠时间长，应该使用多panel。
进一步的，休眠时间可以由DRX周期的长短，drx-onDurationTimer，drx-InactivityTimer联合决定，例如：参考图4：
1.如果只配置了LongCycle DRX
1.1如果在ON状态没有收到PDCCH，休眠时间＝drx-LongCycle-drx-onDurationTimer；
1.2如果在ON状态收到PDCCH，drx-InactivityTimer启动，休眠时间＝drx-LongCycle–并集(drx-onDurationTimer，drx-InactivityTimer)；
2.如果还配置了ShortCycle DRX，那么在短周期DRX状态：
2.1如果在ON状态没有收到PDCCH，休眠时间＝drx-ShortCycle-drx-onDurationTimer；
2.2如果在ON状态没有收到PDCCH，休眠时间＝drx-ShortCycle-并集(drx-onDurationTimer，drx-InactivityTimer)；
S105：基于激活的panel，基站和UE之间重新进行波束对齐
波束管理可以由基站来触发，基站向UE下发用于指示波束管理资源的信令或指示信息，可以通过RRC，MAC-CE，DCI等控制信令或控制信息中的一个或多个来进行；用于配置或激活波束管理资源，配置或激活波束管理资源可以考虑S200中的UE上报的能力，不超出UE能力进行配置。
例如：上行波束管理中，基站配置或激活一个或多个SRS资源/SRS资源集合。相应的，UE应该使用基站配置或激活的SRS资源或SRS资源集合进行波束训练。
根据S104，休眠时间小于或等于(或小于)预设时间长度门限，UE采用“单panel模式”进行波束训练，UE发送SRS的panel为所述单panel；当然也可以为部分或少数panel。
如果休眠时间大于(或大于或等于)预设时间长度门限，UE采用“多panel模式”进行波束训练，UE发送SRS的panel为多panel，或全部panel。波束训练也可以称为波束扫描或波束管理。
另外，“单panel模式”或“多panel模式”也可以用于下行波束管理，例如接收测量基站下发的CSI-RS。
根据S104，休眠时间小于或等于(或小于)预设时间长度门限，UE采用“单panel模式”进行波束管理，UE测量基站发送CSI-RS的panel为所述单panel；当然也可以为部分或少数panel。
如果休眠时间大于(或大于或等于)预设时间长度门限，UE采用“多panel模式”进行波束训练，UE测量基站发送CSI-RS的panel为多panel，或全部panel。
单panel模式适用于发送和/或接收panel已确定的情况下，UE在一个较小的范围内寻找最优的发送和/或接收波束的场景。
多panel模式适用于需要在多个panel中选择最优panel的场景，UE需要扫描的范围较大，便于找到合适的可以与基站通信的波束。
经过上述波束训练的过程后，UE可以确定与基站通信的波束；波束训练后，可以只使用该波束对应的panel，关闭其他panel或关闭其他部分panel，当然也可以不关闭panel。
因此，UE不期待在休眠时间小于(或小于或等于)预设的门限时被配置多panel的波束管理资源，因为此时只激活了单个panel；UE不期待在休眠时间大于(或大于或等于)预设的门限时被配置单panel的波束管理资源，因为此时打开了多个或全部的panel。
以UL SRS发送为例，如果基站能够明确配置每一个SRS的发送panel，那么‘单panel的波束管理资源’指所有的SRS资源的panel指示相同。而‘多panel的波束管理资源’指所有的SRS资源的panel指示可以不同。
总之，UE在休眠时间小于(或小于或等于)预设的门限时使用单panel模式；UE休眠时间大于(或大于或等于)预设的门限时使用多panel模式。
仍以上行SRS发送为例，如果基站不能明确配置每一个SRS的发送panel，那么‘单panel模式’指UE使用一个panel发送所有的SRS资源。而‘多panel模式’指UE使用多个panel发送所有的SRS资源。
本申请中，多panel模式可以是UE依次使用多个panel，也可以是UE同时使用多个panel，例如：UE依次使用多个panel进行波束训练，也可以同时使用多个panel进行波束训练。
S106：UE在DRX ON状态与基站进行通信。
UE根据S105波束训练的结果，采用合适的波束与基站进行通信，通信内容包括但不限于按照基站的配置监测PDCCH，测量CSI-RS和上报，发送SRS，发送上行PUCCH，传输PDSCH/PUSCH等。
当然，通信的过程中也可能波束发生变化，采用新的波束进行通信。
S107：UE再次进入休眠状态。
按照DRX配置UE再次进入休眠状态，进入下一个DRX周期。
上述实施例中，UE根据两次DRX ON状态之间休眠时间的长短进行panel的激活，便于及时打开合适的panel，并进一步的找到合适的波束与基站通信，节省了UE的功耗。
在另一个实施例中，UE可以根据两次DRX ON状态之间休眠时间的长短确定使用哪个波束作为默认波束与基站进行通信，便于及时找到合适的波束，这样，可以只打开默认波束对应的panel， 从而降低了UE的功耗。具体的，如图5所示，该波束管理的方法包括：
S200，UE能力上报，可以参考S100，不再详述，该步骤为可选。
S201：基站发送配置信息给UE。
本实施例涉及的配置信息包括：DRX配置，可以参考DRX的介绍部分。
配置信息还可以包括以下一项或多项：
下行控制信道配置，包括下行控制信道波束的指示；
上行控制信道配置，包括上行控制信道波束的指示；
下行数据信道配置，包括下行数据信道波束的指示；
上行数据信道配置，包括上行数据信道波束的指示。
下行控制信道可以为PDCCH，上行控制信道可以为PUCCH，下行数据信道可以为PDSCH，上行数据信道可以为PUSCH；上述各个配置分别指示发送各个信道的波束。
其它内容可以参考S101，不再详述。
S202：UE在DRX ON状态与基站进行通信。
与S102类似，通信内容包括但不限于按照配置监测PDCCH，测量CSI-RS和上报，发送SRS，发送上行PUCCH，传输PDSCH/PUSCH等。
S203：UE进入休眠状态。
UE按照DRX配置进入休眠状态，例如不再监测PDCCH。
S204：UE再次进入DRX ON状态，选择与基站通信的默认波束。
根据休眠时间长短，UE确定与基站通信的默认波束；例如：
如果休眠时间小于(或小于或等于)预设的门限，则使用上一次使用的波束作为默认波束与基站进行通信；或如果休眠时间大于或等于(或大于)预设的门限，则使用随机接入时确定的波束作为默认波束与网络设备进行通信。例如：UE采用上述确定的默认波束监测控制信道PDCCH。
休眠时间小于或等于预设时间长度门限，UE使用最近一次使用的波束作为默认波束与基站进行通信，例如上次DRX ON状态时与基站通信的波束，或上一次基站配置或激活的波束。
最近一次使用的波束可以包括以下一个或多个，例如：
最近一次使用的接收PDCCH/PDSCH/CSI-RS的波束；
最近一次配置或激活的接收PDCCH/PDSCH/CSI-RS的波束；
最近一次使用的发送PUCCH/PUSCH/SRS/RACH的波束；
最近一次配置或激活的发送PUCCH/PUSCH/SRS/RACH的波束；
UE可以使用最近一次使用的波束作为默认波束接收PDCCH/PDSCH/CSI-RS等，发送PUCCH/PUSCH/SRS/RACH等。
休眠时间大于预设时间长度门限，UE采用随机接入时确定的波束作为默认波束与基站进行通信，例如：监听PDCCH。随机接入确定的波束可以包括以下一个或多个：初始接入时确定的波束、链路重配过程中确定的波束或重新定时或上行同步过程中确定的波束。
通信内容同样包括：接收PDCCH/PDSCH/CSI-RS等，发送PUCCH/PUSCH/SRS/RACH等。
上述默认波束已经确定，则UE只需要打开上述默认波束对应的panel即可；当然也可以打开部分panel或全部panel，本实施例不限定。
另外，如果休眠时间内有任何波束管理行为，UE可以根据波束管理结果重新确定与基站通信的波束。
目前在标准讨论关于唤醒信号(wake-up signal)，如果有唤醒信号的存在，UE在休眠期间仍有机会做波束测量或波束选择。
如果S201已经配置相关信道的波束，例如已经配置了下行控制信道的波束，使用上述默认波束覆盖掉已配置的波束。
上述例子中，UE再次进入DRX ON状态时，激活默认波束对应的panel，当然也可以激活全部的panel或部分panel，其中包括默认波束对应的panel即可。
休眠时间的计算与S204类似，不再详述。
在另外一个例子中，最近一次使用的波束，也可以用预先设置的波束来替换，例如：预先设定的波束可以为以下一个或多个：
波束id最低和/或最高的波束；
接收和/或发送低频信号使用的波束；
发送功率最高和/或最低的波束。
S205：UE在DRX ON状态采用确定的默认波束与基站进行通信。
另外，采用默认波束与基站进行通信除了监听PDCCH，还可以包括：接收PDCCH/PDSCH/CSI-RS等，发送PUCCH/PUSCH/SRS/RACH等，但不限于以下类型，例如：
基站发送数据或PDSCH，UE接收数据或PDSCH。
UE发送上行控制信道，例如PUCCH，基站接收UE发送的上行控制信道。
UE发送上行数据信道，例如PUSCH，基站接收UE发送的上行数据信道。
同样，如果S201已经配置了上述相关信道或信号的波束，本实施例可以使用确定的默认波束覆盖掉已有配置。
在采用默认波束与基站通信的过程中，如果终端设备使用所述默认波束接收到网络设备下发的用于指示波束管理资源的信令或消息，则可以进行波束训练；具体可以使用默认波束对应的panel进行波束训练，也可以使用部分或全部panel进行波束训练。例如：
如果休眠时间小于预设的门限，终端设备使用单个panel进行波束训练，如使用上一次使用的panel进行波束训练，即上一次DRX ON状态与基站通信时使用的panel或上一次使用的波束对应的panel进行波束训练；如果休眠时间大于或等于预设的门限，终端设备使用多个panel或全部的panel进行波束训练；该过程与S105的各种情况类似，可以参考上一个实施例，不再详述。
另外，也可以不考虑休眠时间的长短，直接使用全部的panel进行波束训练。
波束训练后，可以重新确定与基站通信的波束。
S206：UE在DRX ON状态与基站正常通信。
通信过程中，如果基站重新配置了通信波束，则UE采用新配置的波束与基站进行通信，例如 基站重新配置了PDCCH波束，那么UE停止使用默认波束，开始使用基站重新配置的波束监听PDCCH。例如：PDCCH的波束是按照CORESET配置的，如果基站重配CORESET#1的波束，那么CORESET#1使用基站新配置的波束接收，而其他的CORESET仍然使用默认波束接收，直到基站重新配置。
与PDCCH类似，上述方法也适用于PDSCH/PUCCH/PUSCH/CSI-RS/SRS等信道和信号的传输。
正常通信包括但不限于按照配置监测PDCCH，测量和上报CSI-RS，发送SRS，发送上行PUCCH，传输PDSCH/PUSCH等；也可以采用基站重新配置的波束进行通信。
类似的，在与基站正常通信的过程中，如果终端设备接收到网络设备下发的用于指示波束管理资源的信令或消息，则可以进行波束训练；具体可以使用默认波束对应的panel进行波束训练，也可以使用部分或全部panel进行波束训练。例如：
如果休眠时间小于预设的门限，终端设备使用单个panel进行波束训练，如使用上一次使用的panel进行波束训练，即上一次DRX ON状态与基站通信时使用的panel或上一次使用的波束对应的panel进行波束训练；如果休眠时间大于或等于预设的门限，终端设备使用多个panel或全部的panel进行波束训练；
如果休眠时间大于或等于预设的门限，终端设备也可以使用单个panel进行波束训练，例如：使用随机接入时确定的波束对应的panel进行波束训练。
上述过程与S105类似，不再详述。
UE可以根据波束训练的结果选择合适波束与基站进行通信，也可以将波束训练的结果上报基站，由基站确定合适的波束并通知UE。
S207：UE再次进入休眠状态。
通信结束后，UE按照DRX配置再次进入休眠状态，进入下一个DRX周期。
上述各个实施例中，基站向UE下发的配置信息还可以包括：
1，波束管理资源测量周期，与DRX周期相关，可以与DRX周期相同，也可以为DRX周期的整数倍；包括以下一种或多种：
专用的波束管理配置，包括上行或者下行的波束管理资源的配置等，例如：UE每次进入DRX ON状态，都有波束管理资源机会，而无需基站调度波束训练；
进一步的，仅当休眠时间大于门限时，UE进入DRX ON状态，UE进行波束训练；因为休眠时间过短，不需要进行波束训练。
2，波束上报周期，与DRX周期相关，可以与DRX周期相同，也可以为DRX周期的整数倍；包括以下一种或多种：
专用的上报配置，包括上报的时频资源等，用于UE每次进入DRX ON状态，都有一个上报资源用于波束上报，而无需基站调度波束上报；
进一步的，仅当休眠时间大于门限时，UE进入DRX ON状态，UE进行上报；因为休眠时间过短，不需要进行波束训练。
3，每个panel的DRX周期配置。
例如：所有DRX的相关参数都加上用于标识panel的信息，例如，panel id。
本申请中，Panel标识(id)是指一种用于标识panel的信息，包括：物理panel的标识和/或逻辑panel的标识。如果一个panel与一个或多个参考信号或参考信号的集合有关联关系，那么panel id也可以是该参考信号或参考信号的集合的标识。
上述实施例中的大于也可以为大于或等于，小于也可以为小于或等于，反之即可，“/”通常表示和/或的关系，如果连续多个，可以表示取其中一个或多个。
本申请中网络设备下发给终端设备的各种信息，如，配置信息，门限等，可以由网络设备配置，下发给终端设备，配置信息可以承载在物理广播信道(Physical Broadcast Channel，PBCH)、剩余最小系统信息(Remaining minimum system information，RMSI)、系统信息块(System Information Block，SIB)1、SIB2、SIB3，媒体接入控制控制元素(Media Access control-control element，MAC-CE)、下行控制信息(Down link control information，DCI)、无线资源控制(Radio Resource Control，RRC)以及系统信息中的任意一项或多项；所述各种信息也可以由标准规定，或者网络设备和终端设备预先约定。
本申请中终端设备上报给网络设备的各种信息，可以由上行的物理层信息进行传输，如上行控制信息(uplink control information,UCI)，或由上行的高层信息进行传输，例如上行MAC-CE，上行RRC等。
由于波束通常与SSB或CSI-RS对应，本申请中的波束也可以用SSB，或CSI-RS来表示，或者称为SSB或CSI-RS对应的波束。
还应理解，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
还应理解，本申请实施例中，“预先设定”、“预先定义”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
