目前,在传统的波束管理过程中,终端设备需要根据网络设备所配置的用于上报波束测量结果的时频资源进行波束测量,得到并向网络设备上报波束测量的测量结果;此后,网络设备再依据一个或多个终端设备所上报的测量结果进行调控,并下发用于波束管理的指令,以使得终端设备依据该指令执行波束管理。例如终端设备依据该指令保持原波束与网络设备通信或使用新的波束与网络设备通信等。
然而,当终端设备移动、旋转或姿态变化等原因导致原波束质量恶化或原波束不可用的情况发生时,由于网络设备需要根据终端设备所上报的测量结果进行调控并下发用于波束管理的指令,才可以触发终端设备执行波束管理,这将导致波束管理过程存在较大的时延,影响通信质量。

(2)网络设备:可以是无线网络中的设备,例如网络设备可以为将终端设备接入到无线网络的RAN节点(或设备),又可以称为基站。目前,一些RAN设备的举例为:5G通信系统中的新一代基站(generation Node B,gNodeB)、传输接收点(transmission reception point,TRP)、演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved Node B, 或home Node B,HNB)、基带单元(base band unit,BBU),或无线保真(wireless fidelity,Wi-Fi)AP等。另外,在一种网络结构中,网络设备可以包括集中单元(centralized unit,CU)节点、或分布单元(distributed unit,DU)节点、或包括CU节点和DU节点的RAN设备。
其中,网络设备能够向终端设备发送配置信息(例如承载于调度消息和/或指示消息中),终端设备进一步根据该配置信息进行网络配置,使得网络设备与终端设备之间的网络配置对齐;或者,通过预设于网络设备的网络配置以及预设于终端设备的网络配置,使得网络设备与终端设备之间的网络配置对齐。具体来说,“对齐”是指网络设备与终端设备之间存在交互消息时,两者对于交互消息收发的载波频率、交互消息类型的确定、交互消息中所承载的字段信息的含义、或者是交互消息的其它配置的理解一致。
此外,在其它可能的情况下,网络设备可以是其它为终端设备提供无线通信功能的装置。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述,本申请实施例并不限定。
网络设备还可以包括核心网设备,核心网设备例如包括访问和移动管理功能(access and mobility management function,AMF)、用户面功能(user plane function,UPF)或会话管理功能(session management function,SMF)等。

(3)配置与预配置:在申请中,会同时用到配置与预配置。配置是指基站/服务器通过消息或信令将一些参数的配置信息或参数的取值发送给终端,以便终端根据这些取值或信息来确定通信的参数或传输时的资源。预配置与配置类似,可以是基站/服务器预先与终端设备协商好的参数信息或参数值,也可以是标准协议规定的基站/服务器或终端设备采用的参数信息或参数值,还可以是预先存储在基站/服务器或终端设备的参数信息或参数值。本申请对此不做限定。进一步地,这些取值和参数,是可以变化或更新的。
(4)DMRS端口指示:网络设备在调度数据,如调度物理下行共享信道(physical downlink shared channel,PDSCH)数据时,需要指示相应的DMRS端口,包括DMRS端口数以及DMRS端口号,不同DMRS端口号对应的DMRS端口所占用的物理资源是正交的,物理资源包括空间资源、时域资源和频域资源中的一个或者多个。其中,DMRS端口数等于PDSCH数据的传输层数,且各个DMRS端口与各个传输层一一对应,解调某个传输层需要在相对应的DMRS端口上执行信道估计。不同的终端设备若占用相同时频资源传输PDSCH数据,则需要网络设备分配不同的DMRS端口号保证DMRS正交。
(5)波束(beam):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,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。
在使用低频或中频的频段时,可以全向发送信号或者通过一个较宽的角度来发送信号,而在使用高频的频段时,得益于高频通信系统较小的载波的波长,可以在发送端和接收端布置很多天线阵子构成的天线阵列,发送端以一定波束赋形权值发送信号,使发送信号形成具有空间指向性的波束,同时在接收端用天线阵列以一定波束赋形权值进行接收,可以提高信号在接收端的接收功率,对抗路径损耗。
(6)准同位(quasi-co-location,QCL),QCL也可以称为准共址:准共址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,对于具有准共址关系的多个资源,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准共址关系,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。具体地,所述准共址指示用于指示所述至少两组天线端口是否具有准共址关系为:所述准共址指示用于指示所述至少两组天线端口发送的信道状态信息参考信号是否来自相同的传输点,或所述准共址指示用于指示所述至少两组天线端口发送的信道状态信息参考信号是否来自相同的波束组。
其中,QCL信息用于辅助描述终端设备接收侧波束赋形信息以及接收流程。当前标准中定义了四种类型的QCL假设信息,所述四种类型的QCL假设信息为:QCL类型(types)A:多普勒偏移(doppler shift)、多普勒扩展(doppler spread)、平均信道时延(average delay)、时延扩展(delay spread);QCL types B:doppler shift、doppler spread;QCL types C:average delay、doppler shift;QCL types D:空间接收参数(spatial rx parameter)。其中,为了节省网络设备对终端设备的QCL信息指示开销,PDSCH或者PDCCH的QCL信息指示是通过指示PDCCH(或者PDSCH)的DM-RS端口与某一个或多个参考信号资源中满足QCL假设关系,从而可以通过该关联的一个或者多个参考信号资源获得上述QCL信息并采用该信息接收PDSCH或者PDCCH。如,该参考信号可以是信道状态信息参考信号(channel state information reference signal,CSI-RS),同时,上述DM-RS和CSI-RS具有相同的QCLType D假设,则此时上述DM-RS和CSI-RS具有相同的接收波束,从而基于关联的参考信号资源索引,UE可推断出接收PDCCH(或者PDSCH)的接收波束信息。这些QCL信息为空间特性参数,描述了相关联的两种参考信号包含的天线端口间的空间信道特性,有助于终端设备根据该QCL信息完成接收侧波束赋形或接收处理过程。
(7)参考信号(reference signal,RS):根据长期演进(long term evolution,LTE)系统/新无线(new radio,NR)系统的协议,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),PUSCH等,上行信号包括信道探测信号(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 de-modulation reference signal,PUSCH-DMRS),上行相位噪声跟踪信号(phase noise tracking reference signal,PTRS),上行定位信号(uplink positioning RS)等等。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),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 de-modulation reference signal,PDCCH-DMRS),下行数据信道解调参考信号(PDSCH de-modulation reference signal,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系统中没有CRS而LTE系统中有CRS),TRS(LTE没有TRS而NR系统中有TRS),LTE/NR的定位信号(positioning RS)等。
(8)传输配置指示(transmission configuration indicator,TCI):协议中高层通过TCI-状态(TCI-State)来配置QCL,TCI-State的参数用于在一到两个下行参考信号和PDSCH的DMRS之间配置准共址关系。其中,指示TCI的字段为DCI中用于指示PDSCH天线端口准共址的字段。
可选的,TCI由无线资源控制(radio resource control,RRC)配置,在配置信令中称为TCI-state。并且,基站通过RRC配置TCI后,由基站发送媒体接入控制的控制单元(media access control control element,MAC CE)激活一个或多个TCI状态。此外,基站可以进一步发送DCI指示多个被激活TCI中的一个。
TCI包括一个或者两个QCL关系或者多个QCL关系,其中,QCL表征了当前将要接收的信号/信道,与之前已知的某参考信号之间的某种一致性关系。若存在QCL关系,UE可以继承之前接收某参考信号时的接收或发送参数,来接收或发送将要到来的信号/信道。
此外,如果TCI状态中包含标识为QCL Type-D的信息,则该TCI可以用于指示波束。QCL Type-A/B/C用于指示时域与频域偏移等信息,不包括空域信息,一般用于辅助终端进行数据接收解调。
(9)在本申请中,“用于指示”可以包括用于直接指示和用于间接指示。当描述某一指示信息用于指示A时,可以理解为该指示信息携带A、直接指示A或间接指示A。
本申请中,指示信息所指示的信息,称为待指示信息。在具体实现过程中,对待指示信息进行指示的方式有很多种,例如但不限于,可以直接指示待指示信息,如待指示信息本身或者该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息,其中该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分,而待指示信息的其他部分则是已知的或者提前约定的。例如,还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示,从而在一定程度上降低指示开销。
待指示信息可以作为一个整体一起发送,也可以分成多个子信息分开发送,而且这些子信息的发送周期和/或发送时机可以相同,也可以不同。具体发送方法本申请不进行限定。其中,这些子信息的发送周期和/或发送时机可以是预先定义的,例如根据协议预先定义的,也可以是发射端设备通过向接收端设备发送配置信息来配置的。其中,该配置信息可以例如但不限于包括无线资源控制信令、MAC层信令和物理层信令中的一种或者至少两种的组合。其中,无线资源控制信令例如RRC信令;MAC层信令例如包括MAC控制元素(control element,CE);物理层信令例如包括DCI。
(10)本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,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的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“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和C中的至少一个”包括A,B,C,AB,AC,BC或ABC。以及,除非有特别说明,本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。

此外,在图1a中,UE4-UE6也可以组成一个通信系统,此时,配置信息发送实体和接收实体可以都是UE,其中,UE5作为网络设备,即配置信息发送实体;UE4和UE6作为终端设备,即配置信息接收实体。例如车联网系统中,UE5分别向UE4和UE6发送配置信息,并且接 收UE4和UE6发送的上行数据;相应的,UE4和UE6接收UE5发送的配置信息,并向UE5发送上行数据。
如图1a所示,本申请针对的场景主要包括基站(网络设备)和UE(终端设备),具体可以包括单个(或多个)网络设备,以及单个(或多个)终端设备。示例性的,以图1b所示单个网络设备和单个终端设备的通信场景为例,网络设备可以向终端设备传输数据或控制信令。具体的,基于网络的配置信息,终端设备可以上报参考信号的测量结果(对应于波束),用于切换该终端设备的服务波束。

应理解,前述图1a、图1b和图1c所示通信场景仅仅为示例,本申请对于通信系统中终端设备的数量和网络设备的数量不作具体的限定。
如上述图1a、图1b和图1c所示通信场景,网络设备和终端设备之间可以基于波束进行通信。其中,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。
目前,在传统的波束管理过程中,终端设备需要根据网络设备所配置的用于上报波束测量结果的时频资源进行波束测量,得到并向网络设备上报波束测量的测量结果;此后,网络设备再依据一个或多个终端设备所上报的测量结果进行调控,并下发用于波束管理的指令,以使得终端设备依据该指令执行波束管理。例如终端设备依据该指令保持原波束与网络设备通信或使用新的波束与网络设备通信等。
传统的波束管理方案中,以终端设备为UE且网络设备为基站为例,UE可以通过如下方式的任意一个或多个的组合实现波束管理:
方式一、UE固定收波束,接收基站通过SSB信号发送的宽波束,UE确定信号质量优异(如RSRP最大)的下行宽波束,并将该下行宽波束作为与基站之间通信的波束;
例如,连接态UE上报SSB测量结果,即UE对SSB进行周期性测量(宽波束测量)的方式以确定该下行宽波束。
方式二、基站在UE确定的质量优异的宽波束的范围内,使用多个窄波束进行波束扫描。UE在多个窄波束中确定质量优异的下行窄波束,并将该质量优异的下行窄波束作为与基站之间通信的波束;
例如,基站配置CSI-RS对应的多个窄波束进行扫描,指示PDCCH和PDSCH对应的波束,终端侧使用相应的宽波束接收,测量并上报基站侧该UE所测量到质量优异的波束对应的窄波束作为该下行窄波束。
方式三、基站固定某个下行窄波束发送参考信号,UE使用不同的窄波束进行接收扫描,确定质量优异的接收波束,并将该质量优异的接收波束作为与基站之间通信的波束。
例如,基站侧使用SRS对应的质量优异波束作为下行窄波束为UE配置PUCCH和PUSCH,UE在PUCCH和PUSCH中基于该下行窄波束进行接收扫描以选择质量优异的窄波束。此外,基站侧维护质量优异的波束集合,并且,基站可以针对上下行波束集单独维护。
然而,在上述方式一至方式三中,在UE进行移动、旋转或姿态变化等原因导致原波束质量恶化或原波束不可用的情况发生时,基站并不能及时知道该信息(当终端侧波束质量恶化/波束不可用时,基站无法及时知晓)。并且,需要等到UE下一次测量上报,才会触发基站进行波束管理。UE下一次测量上报的时机取决于基站配置的上报资源以及基站的下行参考信号的周期。若下次上报发生在较长的时长以后,则会严重影响通信的质量。换言之,由于基站需要根据UE所上报的测量结果进行调控并下发用于波束管理的指令,才可以触发UE执行波束管理,这将导致波束管理过程存在较大的时延,影响通信质量。
针对上述问题,当前有人提出了另一种波束管理方式,此处记为方式四。
在方式四中,首先,UE基于基站发送的下行的参考信号进行测量得到测量结果;然后,UE基于配置的上报条件与上报资源,向基站发送测量结果的时候,UE还需要向基站发送波束选择/激活报告(beam selection/activation report)以指示该测量结果对应的波束用于波束切换;并且,经过一段预设的波束激活时延(beam activation latency),基站向UE发送响应消息以指示该测量结果对应的波束生效。此后,UE使用该波束接收下行信号,和/或,UE使用该波束发送上行信号;相应的,基站使用该波束发送下行信号,和/或,基站使用该波束接收上行信号。
然而,基于前述方式四的实现过程,尚不能解决(方式一至方式三中)普通的测量上报与(方式四中)触发波束切换的上报机制共存的问题。具体来讲,当前已有方式一至方式三中测量上报的机制,用于UE上报对参考信号的测量结果;但是,基站并不会将UE的每个测量上报都用于方式四中的触发波束切换。因此,方式四的实现过程仍未能很好地解决前述波束管理过程存在较大的时延的问题。
为此,本申请提供了一种通信方法及通信装置,相比于传统的波束管理过程中存在较大的通信时延的实现方式,网络设备预先指示第一波束用于波束切换,并在终端设备上报第一波束对应的第一测量报告之后,无需等待网络设备下发的用于波束管理的指令,终端设备即可确定该第一波束可以用于波束切换,使得波束管理过程的时延得以减小,从而提升通信质量。
请参阅图2,为本申请实施例提供的通信方法的一个示意图,该方法包括如下步骤。
S101.网络设备发送第一指示信息。
本实施例中,网络设备在步骤S101中向终端设备发送第一指示信息;相应的,该终端设备在步骤S101中接收来自网络设备的第一指示信息。其中,第一指示信息用于指示第一上报配置对应的至少一个RS所关联的第一波束用于波束切换。
可选的,该第一上报配置的类型为层1(layer 1,L1)上报配置。相应的,网络设备在步骤S101所发送的第一指示信息用于指示layer 1上报配置对应的至少一个RS所关联的第一波束用于波束切换。
可选的,将网络设备与终端设备之间用于收发步骤S101中的第一指示信息的波束记为当前的通信波束。该第一上报配置也可以是基于L1测量的事件上报,在以下一种或多种事件满足后触发波束切换:

第二事件:测量的当前的通信波束的质量小于(或等于)偏移值与阈值之和;
第三事件:测量的第一波束的质量大于(或等于)偏移值与当前的通信波束的质量之和;
可选的,第一波束(或第二波束)的质量可以是RSRP、参考信号接收质量(reference signal received quality,RSRQ)等,偏移值可为正数或负数或0,阈值可以为预配置的阈值(或网络设备配置的阈值)。
此外,第一波束对应的PCI与当前的通信波束对应的PCI不同,或,第一波束对应的PCI与当前的通信波束对应的PCI相同。
在一种可能的实现方式中,该第一上报配置包括该至少一个RS(或称为,该至少一个RS包含于该第一上报配置);或,第一上报配置包括第一RS,且该至少一个RS关联于该第一RS(或称为,该至少一个RS关联于第一RS,其中,该第一RS包含于该第一上报配置)。具体地,网络设备在步骤S101所发送的第一指示信息中,第一指示信息所指示的与第一波束相关联的至少一个RS存在多种实现,例如,该至少一个RS可以为第一上报配置所包含的多个RS中的一部分RS;又如,该至少一个RS也可以关联于该一部分RS,此处不做限定。
可选的,至少一个RS关联于第一RS可以表述为至少一个RS与第一RS关联于同一TCI state,还可以表述为至少一个RS与第一RS存在QCL关系。
在一种可能的实现方式中,该至少一个RS包括TRS,其中,该TRS为非重复配置且该TRS与某一个SSB存在准共址QCL关系。
可选的,TRS为非重复配置,指的是该TRS对应的配置信息中存在“重复(repetition)”字段且该字段取值为“关(off)”,或指的是该TRS对应的配置信息中不存在“repetition”字段。可选的,终端设备不应假设网络设备使用了相同的波束发送该TRS。
可选的,用于指示第一上报配置对应的至少一个RS所关联的第一波束用于波束切换的第一指示信息可以是显示配置的,也可以是隐式配置的;例如,当第一上报配置对应的至少一个RS包括TRS,其中,该TRS为非重复配置且该TRS与某一个SSB存在准共址QCL关系时,终端设备可以确定TRS所关联的第一波束用于波束切换。此时,网络设备通过配置的SSB与TRS之间的QCL关系,以隐式的方式配置该第一指示信息,且终端设备基于SSB与TRS之间的QCL关系以隐式的方式确定该第一指示信息。
在一种可能的实现方式中,该第一指示信息满足以下至少一项:
1.第一指示信息包括该至少一个RS的标识。后续终端设备在步骤S102和步骤S103中可以根据至少一个RS的标识,进行测量和上报。
可选的,第一指示信息进一步包括至少一个RS的标识所对应的波束标识,该波束标识可以是TCI state ID或探测参考信号资源索引(sounding reference signal resource index,SRI)或其他用于指示终端设备用于确定接收或发送信号所参考的空间滤波器参数的标识。
可选的,至少一个RS,还可以为至少一个TCI state中QCL Type D的源参考信号(source RS),此时终端将该TCI state关联的波束作为第一波束。或,
2.第一指示信息包括该第一上报配置的标识。示例性的,第一上报配置可以为网络设备所配置的信道参考信号报告配置(CSI-ReportConfig),当第一指示信息包括某一个信道参考信号报告配置标识(CSI-ReportConfigID)的时候,该第一指示信息具体用于指示该CSI-ReportConfigID所指示的上报配置对应的至少一个RS所关联的第一波束用于波束切换;或,
3.第一上报配置包含于基于半持续配置的CSI资源列表,且该第一指示信息还用于指示激活该CSI资源列表中的该第一上报配置。
示例性的,如图3所示为网络设备通过RRC配置的方式,为终端设备下发的基于半持续SP配置的CSI资源列表,该CSI资源列表包括多个用于半持续上报的测量配置(S 0、S 1、S 2、S 3),其中每个测量配置分别关联到一个或多个TCI state;此外,如图3,网络设备还可以向终端设备发送MAC-CE以激活S 0、S 1、S 2、S 3中的一个或多个,所激活的S 0、S 1、S 2、S 3的一个或多个,对应RRC配置的SP上报配置ID由低到高的一个或多个测量上报配置。其中,在网络设备通过第一指示信息(例如第一指示信息为MAC-CE)指示激活S 0、S 1、S 2、S 3中的一个或多个时,第一指示信息还用于指示所激活的TCI state对应的至少一个RS所关联的第一波束用于波束切换。或,
4.第一指示信息包括该第一上报配置所关联的第一TCI state的标识。
示例性的,网络设备在下发第一上报配置的配置信息时,该配置信息包括:上报配置与TCI state ID的关联关系。可选的,该配置信息可以通过RRC或MAC-CE进行指示。例如,网络设备在配置信息中可以配置上报配置ID #1(即第一上报配置)对应TCI state #2,当终端设备基于上报配置ID #1进行上报时,可选的,终端设备可以将TCI state #2对应的波束作为新的服务波束(即第一波束),用于接收PDCCH和或PDSCH信号;或,
5.第一上报配置包含于触发状态列表,且该第一指示信息用于指示该第一上报配置在该触发状态列表中的标识。
示例性的,网络设备在下发第一上报配置的配置信息时,该配置信息用于将至少一个的测量上报配置分别关联至少一个TCI state ID,并添加到同一触发状态列表(trigger state list)(例如,trigger state list为DCI触发CSI上报的配置列表)中。当网络设备发送包含有DCI触发终端设备进行非周期的CSI测量上报时,终端设备基于配置信息中预先关联的TCI state ID确定切换的波束。例如,将关联的TCI state ID对应的波束 作为新的服务波束(即第一波束),用于接收PDCCH和或PDSCH信号。
可选的,如果trigger state list中的多个测量上报配置所属的资源分别属于不同CC,当第一上报配置的测量结果满足条件时,基于配置信息预配置的关联关系,终端设备在多CC上分别应用相应TCI指示的波束。
可选的,如果trigger state list中的多个测量资源预配置关联某个控制资源池标识(control resource set pool ID,CORESET pool ID),当第一上报配置的测量结果满足条件时,终端设备接收多个PDCCH时,分别应用控制资源池中相应的TCI state ID所指示的波束作为新的服务波束(即第一波束)。
具体地,网络设备在步骤S101所发送的用于指示第一上报配置对应的至少一个RS所关联的第一波束用于波束切换的第一指示信息,可以通过上述多种方式指示用于波束切换的波束为该第一波束。
可选的,终端设备可以基于网络设备的配置确定该第一指示信息满足上述至少一项;或,终端设备基于预配置的方式确定该第一指示信息满足上述至少一项,此处不做限定。此外,当终端设备基于网络设备的配置确定该第一指示信息满足上述至少一项时,该网络设备的配置可以与第一指示信息承载于同一条消息中,也可以承载于不同消息中,此处不做限定。
S102.终端设备基于第一上报配置进行测量,得到第一测量报告。
本实施例中,终端设备在步骤S102中基于步骤S101得到的第一指示信息所对应的第一上报配置进行测量,基于测量结果生成第一测量报告。
在一种可能的实现方式中,终端设备在步骤S102中,基于第一上报配置进行测量,得到第一测量报告之后,无需其他条件,终端设备即可确定该第一上报配置所关联的第一波束用于波束切换。并且,在步骤S102之后,该终端设备可以基于该第一波束(立即或一段时延之后)与网络设备进行通信。
在一种可能的实现方式中,终端设备在步骤S102中,基于第一上报配置进行测量,得到第一测量报告之后;该终端设备还需要进一步确定在满足如下至少一项时,该第一上报配置所关联的第一波束用于波束切换,包括:
至少一个RS的RSRP大于第一阈值;或,
至少一个RS的SINR大于第二阈值;或;
至少一个RS所关联的TCI state为已激活的TCI state;或,
第一上报配置为基于周期性的方式所配置的配置信息;或,
第一上报配置为基于半持续(semi-persistence,SP)的方式所配置的配置信息;或,
第一上报配置为基于非周期配置的方式所配置的配置信息;或,
第一上报配置为基于非周期配置的TRS所配置的配置信息。
具体地,网络设备在步骤S101所发送的第一指示信息所指示的第一波束并非必然可用于波束切换,还可以通过上述任意一项或多项条件的限制,以确保该第一波束为终端设备测量得到的满足条件的波束或该第一波束为网络设备所配置的特定条件所对应的波束。
可选的,终端设备可以基于网络设备的配置确定满足上述至少一项时,该第一上报配置所关联的第一波束用于波束切换;或,终端设备基于预配置的方式确定满足上述至少一项时,该第一上报配置所关联的第一波束用于波束切换,此处不做限定。此外,当终端设备基于网络设备的配置确定满足上述至少一项时,该网络设备的配置可以与第一指示信息承载于同一条消息中,也可以承载于不同消息中,此处不做限定。
在一种可能的实现方式中,在该终端设备基于该第一上报配置进行测量,得到第一测量报告之前,该方法还包括:该终端设备接收来自该网络设备的该第一上报配置的配置信息。
在一种实现方式中,第一上报配置的配置信息与步骤S101中的第一指示信息承载于同一条消息中,如图4所示。其中,网络设备可以通过步骤S101所发送的一个消息同时承载第一指示信息和第一上报配置的配置信息。
在另一实现方式中,第一上报配置的配置信息与步骤S101中的第一指示信息承载于不同消息中,如图5所示。其中,网络设备可以分别在步骤S100中发送第一上报配置的配置信息,并在步骤S101发送第一指示信息。
需要说明的是,在实际应用中,图5所示步骤S100和步骤S101的执行顺序不做限定,即步骤S100可以在步骤S101之前执行,或步骤S100可以在步骤S101之后执行,此处不做限定。

第一字段,在该第一字段的取值为第一预设值时,该第一字段指示允许该第一波束用于波束切换。示例性的,网络设备在第一上报配置中增加字段,显式表示该第一上报配置可用于触发波束切换。例如,在第一上报配置中增加一个字段“波束切换(beam switch)(或称为波束调整、切换波束等)”作为第一字段,且该字段配置的取值为使能(enable)(或取值为特定值“1”或“0”或“11”或“111”等取值)时,则表示第一上报配置可用于波束切换;或,
第二字段,在该第二字段的取值为第二预设值时,该第二字段用于指示该第一波束用于该多个载波CC的波束切换。示例性的,可以进一步包括载波(component carrier,CC)组生效的指示信息,用于指示基于第一上报配置所上报的波束切换是否应用于多个CC。可选的,载波也可以承载服务小区(serving cell)。
基于上述技术方案,网络设备所下发的该第一上报配置的配置信息中,还可以包括上述至少一项信息,以使得终端设备在基于第一波束进行波束切换的过程中,可以通过上述至少一项信息对该波束切换的过程进一步完善。
需要说明的是,该第一上报配置的配置信息包括第一字段时,在步骤S102之前,网络设备可以向终端设备发送第一字段和第一指示信息中的一个,也可以向终端设备发送第一字段和第一指示信息。下面将以图5所示的示例进行示例性描述。
例如,当网络设备在步骤S102之前向终端设备发送第一字段而不发送第一指示信息时,网络设备和终端设备执行图5所示步骤S100而不执行步骤S101。示例性的,网络设备通过步骤S100中的承载于第一配置信息的第一字段指示第一波束可用于波束切换,使得终端设备基于该第一字段(而无需第一指示信息的指示)即可确定第一波束用于波束切换。
又如,当网络设备在步骤S102之前向终端设备发送第一指示信息而不发送第一字段时,网络设备和终端设备执行图5所示步骤S101而不执行步骤S100。示例性的,网络设备通过步骤S101中的第一指示信息指示第一波束用于波束切换,使得终端设备基于该第一指示信息(而无需第一字段的指示)即可确定第一波束用于波束切换。
又如,当网络设备在步骤S102之前向终端设备发送第一指示信息且发送第一字段时,网络设备和终端设备执行图5所示步骤S101且执行步骤S100。示例性的,网络设备通过步骤S100中的承载于第一配置信息的第一字段指示第一波束(以及可能存在的其他波束都是)可用于波束切换,使得终端设备确定第一波束(以及可能存在的其他波束都是)可以用于波束切换;此后,网络设备通过步骤S101中的第一指示信息指示(第一波束以及可能存在的其他波束中的)第一波束用于波束切换,使得终端设备基于该第一字段和第一指示信息确定用于波束切换的波束为第一波束。
可选的,第一预设值和第二预设值可以为相同的取值,也可以为不同的取值,此处不做限定。此外,当第一上报配置的配置信息同时包括该第一字段和第二字段时,可以通过单独的比特信息分别承载该第一字段和第二字段,也可以通过联合的比特信息同时指示该第一字段和第二字段,此处不做限定。
可选的,将网络设备与终端设备之间用于收发步骤S101中的第一指示信息的波束记为当前的通信波束。而当前的通信波束所对应的PCI与第一波束所对应的PCI可以是相同的,也可以是不同的。
此外,第一波束所对应的PCI可以通过显示的方式指示,例如上述第一上报配置的配置信息包含有PCI。第一波束所对应的PCI可以通过隐示的方式指示,例如,上述第一上报配置的配置信息包含TCI state标识时,该TCI state标识关联的PCI即为第一波束所对应的PCI;又如,上述第一上报配置的配置信息包含第二字段时,该CC组关联的PCI即为第一波束所对应的PCI;又如,通过前述步骤S101中第一指示信息所包含的一个或多个标识(至少一个RS的标识、第一上报配置的标识、基于半持续配置的CSI资源列表等)时,一个或多个标识所关联的PCI即为第一波束所对应的PCI。
可选的,上述第一上报配置的配置信息包含TCI state标识时,该TCI state标识对应的TCI state的QCL Type D的参考源参考信号(source RS)配置对应的PCI为第一波束所对应的PCI。
在一种可能的实现方式中,该第一上报配置的配置信息承载于第二DCI,该第二DCI用于调度PUSCH的数据。具体地,网络设备所下发的包括该第一上报配置的配置信息的第 一上报配置的配置信息具体可以承载于某一DCI(例如第二DCI)中,提供了第一上报配置的配置信息的一种具体的承载方式。
可选的,用于指示第一上报配置对应的至少一个RS所关联的第一波束用于波束切换的第一指示信息可以是显示配置的,也可以是隐式配置的;例如,当第一上报配置的配置信息具体可以承载于某一DCI(例如第二DCI)且该第二DCI用于调度PUSCH数据时,该第二DCI可以为格式0_2的DCI(DCI 0_2),此时网络设备通过该第二DCI以隐式的方式配置该第一指示信息,且终端设备基于接收得到的第二DCI以隐式的方式确定该第一指示信息。
S103.终端设备发送第一测量报告。
本实施例中,终端设备在步骤S103中向网络设备发送第一测量报告;相应的,该网络设备在步骤S103中接收来自终端设备的第一测量报告。
在一种可能的实现方式中,该方法还包括:该终端设备向该网络设备发送第一能力信息,该第一能力信息用于指示该第一波束的生效时长。
可选的,第一能力信息和步骤S103中的第一测量报告承载于同一条消息中。
可选的,第一能力信息和第一测量报告承载于不同消息。例如,终端设备可以在步骤S103中向网络设备发送第一测量报告之前,向网络设备发送第一能力信息;又如,终端设备可以在步骤S103中向网络设备发送第一测量报告之后,向网络设备发送第一能力信息。又如,终端设备可以在步骤S101中接收第一指示信息之前,向网络设备发送第一能力信息;又如,终端设备可以在步骤S101中接收第一指示信息之后,向网络设备发送第一能力信息。
具体地,受限于通信时延或射频调整时延等,终端设备还可以向网络设备发送用于指示该第一波束的生效时长的第一能力信息,以使得网络设备根据该第一能力信息明确该第一波束的生效时长,在该第一波束的生效时长对应的生效时刻之后,基于第一波束与终端设备进行通信。
进一步的,在该第一波束的生效时长对应的生效时刻之前,该方法还包括:该终端设备接收来自该网络设备的第二TCI state信息,该第二TCI state信息所指示的RS对应的第二波束用于波束切换;此后,该终端设备根据该第二波束接收下行数据。具体地,在第一波束的生效时长所指示的生效时刻之前,终端设备还可以依据网络设备发送的第二TCI state信息所指示的RS对应的第二波束接收下行数据,即终端设备根据网络设备临时/最新配置的第二波束接收来自网络设备的下行数据,以提升方案实现的灵活性。
可选的,终端设备还可以进一步通过预配置的方式或基于网络设备配置的方式确定该第二TCI state信息所指示的RS对应的第二波束的生效时长。
可选的,终端设备还可以基于第一波束的生效时长和第二波束的生效时长进行比较,以确定所切换的波束为第一波束还是第二波束。例如,在时域上,若第一波束的生效时长对应的生效时刻位于第二波束的生效时长对应的生效时刻之前,则终端设备在步骤S103之后确定使用第一波束作为与网络设备通信的波束;若第一波束的生效时长对应的生效时刻位于第二波束的生效时长对应的生效时刻之后,则终端设备在步骤S103之后确定使用第二波束作为与网络设备通信的波束。
在一种可能的实现方式中,终端设备在步骤S103中向该网络设备发送该第一测量报告之后,该方法还包括:该终端设备接收来自该网络设备的第二指示信息,该第二指示信息用于指示该第一测量报告指示的波束生效;或,该终端设备接收来自该网络设备的第三指示信息,该第三指示信息用于指示该第一测量报告在第一时长之后生效;或,该终端设备接收来自该网络设备的第一DCI消息,该第一DCI消息用于指示该第一测量报告所指示的第一波束在第二时长之后生效。
具体地,终端设备在步骤S103中向该网络设备发送该第一测量报告之后,网络设备还可以通过上述多种实现方式以指示该终端设备基于第一测量报告对应的第一波束执行波束切换的生效时刻。以使得终端设备根据网络设备的指示明确该第一波束的生效时刻,并基于该第一波束的生效时刻进行波束切换。
基于上述技术方案,终端设备接收来自网络设备的第一指示信息用于指示第一上报配置对应的至少一个RS所关联的第一波束用于波束切换,此后,该终端设备基于该第一上报配置进行波束测量得到并上报第一测量报告之后,终端设备确定该第一波束可以用于波束切换。相比于传统的波束管理过程中存在较大的通信时延的实现方式,网络设备基于第一指示信息预先指示第一波束用于波束切换,并在终端设备上报第一波束对应的第一测量报告之后,无需等待网络设备下发的用于波束管理的指令,终端设备即可确定该第一波束可以用于波束切换,使得波束管理过程的时延得以减小,从而提升通信质量。
