Description

一种通信方法及相关装置
本申请要求于2022年05月30日提交中国国家知识产权局、申请号为202210601267.0、申请名称为“一种通信方法及相关装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,尤其涉及一种通信方法及相关装置。
背景技术
第五代移动通信系统(5th generation,5G)可以采用高频通信,即采用高频段信号传输数据。高频通信的一个主要问题是信号能量随传输距离急剧下降,导致信号传输距离短。为了克服这个问题,高频通信采用模拟波束技术,通过对天线阵列进行加权处理,将信号能量集中在一个较小的角度范围内,形成一个类似于光束一样的信号(称为模拟波束,简称波束),从而提高传输距离。网络设备和终端设备可以采用特定的波束来进行通信。
定时提前量(timing advance,TA)机制的主要目的是保证系统中的上行信号同时到达基站,避免干扰。目前,终端设备可以配置一组服务小区,其中具有相同上行定时或者相同TA的服务小区在相同的定时提前组(timing advance group,TAG)。终端设备可以上报支持的最大TAG数。但在小区内多传输接收点(transmission and reception point,TRP)场景中,如果相同服务小区的不同站点距离较远,终端设备需要在一个服务小区维护多个TA来保证每个TRP上行传输的定时同步。针对小区间的多TRP场景,如果服务小区和非服务小区的站点距离较远,终端设备也需要维护多个TA来保证小区间的TRP上行传输定时同步。
终端设备可以采用一个或一组波束进行上行传输。采用一组波束时,该一组波束可以位于不同的天线面板上,即通过多个天线面板上的各一个波束进行上行传输,各波束可以同时传输,也可以分时传输。一组波束也可以位于同一个天线面板,但这时该组波束中的各个波束只能进行分时传输,因为一个天线面板在同一时间只能生成一个波束,无法同时采用多个波束进行传输。当网络设备调度终端设备上行传输时,需要提前知道终端设备能否实现多TA同传或多TA时分传输,才能采用合适的方式调度终端设备上传。支持不同传输模式的多TA能力不但是一种终端能力,也是一种波束级的能力。因此,终端设备仅上报支持的最大TAG数,网络设备无法合理地对终端设备进行上行传输调度。
因此,希望提供一种方法,能够提高网络设备对终端设备进行上行传输调度的合理性。
发明内容
本申请提供了一种通信方法及相关装置,以期提高网络设备对终端设备进行上行传输调度的合理性。
第一方面,本申请提供了一种通信方法,该方法可以由终端设备执行,或者,也可以由配置在终端设备中的部件(如芯片、芯片系统等)执行,或者,还可以由能够实现全部或部分终端设备功能的逻辑模块或软件实现,本申请对此不作限定。
示例性地,该方法包括:接收来自网络设备的多个参考信号,该多个参考信号承载于第一资源组中,第一资源组包括多个参考信号资源,且多个参考信号资源中的任意两个参考信号资源来自网络设备配置的不同的参考信号资源集合;根据接收第一资源组的多个参考信号所使用的天线面板,确定第一资源组对应的多TA同传能力,第一资源组对应的多TA同传能力用于指示终端设备接收第一资源组的多个参考信号所使用的天线面板是否支持同时使用多个TA发送上行信号;向网络设备发送第一指示信息和第二指示信息,第一指示信息用于指示第一资源组中所有参考信号资源的索引,第二指示信息用于指示第一资源组对应的多TA同传能力。
基于上述技术方案,终端设备根据接收来自网络设备的多个参考信号时所使用的天线面板,确定第一资源组对应的多TA同传能力,也即,确定接收多个参考信号所使用的天线面板是否支持同时使用多个TA发送上行信号,并将第一资源组中的所有资源的索引和第一资源组对应的多TA同传能力上报给网络设备,以便于网络设备参考上述第一资源组对应的多TA同传能力,对终端设备进行上行传输调度。这样一来,网络设备对终端设备进行上行传输调度时,可以参考终端设备上报的接收参考信号所使用的天线面板是否支持同时使用多个TA发送上行信号,有利于提高网络设备对终端设备进行上行传输调度的合理性。另外,有利于避免由于天线面板不支持同时使用多个TA发送上行信号时,网络设备调度终端设备进行多TA同传导致的调度失败,换言之,有利于提高网络设备进行上行传输调度的成功率。
结合第一方面,在第一方面的某些可能的实现方式中,若第二指示信息指示终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号,上述方法还包括:基于第一资源组关联的一个或多个TA,在第一资源组对应的天线面板上分时或同时发送上行信号。
其中,终端设备基于第一资源组关联的一个或多个TA,在第一资源组对应的天线面板上分时或同时发送上行信号,可以理解为,终端设备可以使用第一资源组关联的一个或多个TA,在第一资源组对应的天线面板上分时或同时发送上行信号。其中,终端设备使用第一资源组关联的一个或多个TA,在第一资源组对应的天线面板上同时发送上行信号时,第一资源组对应的天线面板的个数为多个,换言之,网络设备在确定第一资源组对应的天线面板个数为多个,且第二指示信息指示终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号的情况下,网络设备可能调度终端设备使用第一资源组关联的一个或多个TA,在第一资源组对应的天线面板上同时发送上行信号。
若终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号,则终端设备可以使用第一资源组关联的一个或多个TA在第一资源组对应的天线面板上同时或分时发送上行信号,如此一来,根据终端设备接收第一资源组的多个 参考信号所使用的天线面板支持使用TA的情况,来确定是否可以调度终端设备同时使用多个TA发送上行信号,有利于提高终端设备发送上行信号的合理性与成功率。
结合第一方面,在第一方面的某些可能的实现方式中,若第二指示信息指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联一个TA,上述方法还包括:基于第一资源组关联的一个TA,在第一资源组对应的天线面板上分时或同时发送上行信号。
其中,终端设备基于第一资源组关联的一个TA,在第一资源组对应的天线面板上分时或同时发送上行信号,可以理解为,终端设备可以使用第一资源组关联的一个TA,在第一资源组对应的天线面板上分时或同时发送上行信号。其中,终端设备使用第一资源组关联的一个TA,在第一资源组对应的天线面板上同时发送上行信号时,第一资源组对应的天线面板的个数为多个,换言之,网络设备在确定第一资源组对应的天线面板个数为多个,且第二指示信息指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联一个TA的情况下,网络设备可能调度终端设备使用第一资源组关联的一个TA,在第一资源组对应的天线面板上同时发送上行信号。
若终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联一个TA,则终端设备可以使用第一资源组关联的一个TA在第一资源组对应的天线面板上分时或同时发送上行信号,如此一来,根据终端设备接收第一资源组的多个参考信号所使用的天线面板支持使用TA的情况,来确定是否可以调度终端设备同时发送上行信号,有利于提高终端设备发送上行信号的合理性与成功率。
结合第一方面,在第一方面的某些可能的实现方式中,若第二指示信息指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联多个TA,上述方法还包括:

若终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联多个TA,则终端设备可以使用一个目标TA在第一资源组对应的天线面板上同时发送上行信号,或使用第一资源组关联的多个TA在第一资源组对应的天线面板上分时发送上行信号。如此一来,根据终端设备接收第一资源组的多 个参考信号所使用的天线面板支持使用TA的情况,来确定是否可以调度终端设备同时发送上行信号发送上行信号,有利于提高终端设备发送上行信号的合理性与成功率。

本申请中涉及的信道测量包括波束测量,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接收信号强度(received signal strength indicator,RSSI)、参考信号接收信号功率(reference signal received power,RSRP)等,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,简称信干噪比),预编码矩阵指示(precoding matrix indicator,PMI)、发送预编码矩阵指示(transmitted precoding matrix indicator,TPMI)、秩指示(rank indicator,RI)、发送秩指示(transmitted rank indicator,TRI)、层指示(layer indicator,LI)、TA等参数衡量。
具体地,本申请实施例中涉及的上行参考信号例如可以包括:探测参考信号(sounding reference signal,SRS),解调参考信号(demodulation reference signal,DMRS),下行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)、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)、解调参考信号(demodulation reference signal,DMRS)、以及同步信号块(synchronization signal block,SSB)等。
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索引,例如,CSI-RS资源索引(CSI-RS resource index,CRI)、SSB资源索引(SSB resource index,SSBRI)、SRS资源索引(SRS resource index,SRI)。
其中,SSB资源索引也可以称为SSB时间索引(SSB time 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。
2、波束:可以理解为空域滤波器(spatial domain filter)、空间滤波器(spatial filter)、空域参数(spatial domain parameter)、空间参数(spatial parameter)、空域设置(spatial domain setting)、空间设置(spatial setting)、或准共址(quasi-colocation,QCL)信息、QCL假设、或QCL指示等。波束可以通过传输配置指示状态(transmission configuration indicator  state,TCI-state)参数来指示,或通过空间关系(spatial relation)参数来指示。换言之,在本申请实施例中,波束可以替换为空域滤波器,空间滤波器,空域参数,空间参数,空域设置,空间设置,QCL信息,QCL假设,QCL指示,TCI-state(如下行TCI-state或上行TCI-state),空间关系等,也即上述术语之间相互等效。
应理解,上文所列举的表示波束的术语仅为示例,不应对本申请实施例构成任何限定,在其他的实施例中,波束也可以替换为其他表示波束的术语。
用于发送信号的波束可以称为发送波束(transmission beam,Tx beam),也可以称为空域发送滤波器(spatial domain transmission filter)、空间发送滤波器(spatial transmission filter)、空域发送参数(spatial domain transmission parameter)、空间发送参数(spatial transmission parameter)、空域发送设置(spatial domain transmission setting)、或空间发送设置(spatial transmission setting)。其中,下行发送波束可以通过TCI-state来指示。
用于接收信号的波束可以称为接收波束(reception beam,Rx beam),也可以称为空域接收滤波器(spatial domain reception filter)、空间接收滤波器(spatial reception filter)、空域接收参数(spatial domain reception parameter)、空间接收参数(spatial reception parameter)、空域接收设置(spatial domain reception setting)、或空间接收设置(spatial reception setting)。其中,上行发送波束可以通过空间关系(spatial relation)、上行TCI-state、或SRS资源(SRS资源指示上行发送波束,可以理解为采用某一上行发送波束发送SRS,因此,该承载该SRS的资源可以指示该上行发送波束)来指示。
上文所述的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。
此外,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赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术或者混合数字/模拟波束赋形技术等。
波束可以和参考信号/参考信号资源对应,例如进行波束测量时,网络设备通过不同的参考信号/参考信号资源来测量不同的波束,终端设备反馈测得的参考信号/参考信号资源的质量,网络设备即可得到对应的波束的质量。
可选地,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。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。
在本申请实施例中,在波束测量时,网络设备的每一个波束对应一个参考信号/参考信号资源,因此可以以参考信号资源的索引来唯一标识该资源对应的波束。
3、天线面板:可以简称面板(panel)。可以是网络设备的天线面板,也可以是终端设备的天线面板。一个天线面板上可以有一个或多个天线,这些天线排列成天线阵列,进行波束赋形,从而形成模拟波束。该天线阵列可以生成指向不同方向的模拟波束。也就是说,每个天线面板上都可以形成多个模拟波束,可以通过波束测量来确定该天线面板模拟波束的质量,进而确定出哪些波束质量较好。终端设备可以配备多个天线面板,这些天线面板可以分布在不同的位置,朝向不同的方向,进而保证不论终端设备朝向哪个方向,都至少有一个天线面板是朝向网络设备的,可以与网络设备进行数据传输。终端设备可以同 时开启所有天线面板进行传输。或者,为了降低终端设备功耗,终端设备也可以一次只采用单个天线面板进行传输,其他未使用的天线面板可以进行关闭。终端设备可以将天线面板的状态(处于打开还是关闭状态)通知给网络设备,也就是说,终端设备和网络设备之间可以交互天线面板的状态信息。
在本申请实施例中,若未做出特别说明,天线面板均指终端设备的天线面板。在协议中,天线面板可以用panel,panel索引(index)等来表示。
除此之外,也可以通过其他方式来隐含表示天线面板,例如,天线面板可以通过天线端口(如CSI-RS端口、SRS端口、DMRS端口、相位跟踪参考信号(phase tracking reference signal,PTRS)端口、小区参考信号(cell reference signal,CRS)端口、时频跟踪参考信号(tracking reference signal,TRS)端口、或SSB端口等)或天线端口组来表征。
又例如,天线面板可以通过资源(如CSI-RS资源、SRS资源、DMRS资源、PTRS资源、CRS资源、TRS资源、或SSB资源等)或资源组来表征。
再例如,天线面板可以通过某个信道表征(例如物理上行控制信道(physical uplink control channel,PUCCH)、物理上行共享信道(physical uplink sharing channel,PUSCH)、物理随机接入(physical random access channel,PRACH)、物理下行共享信道(physical downlink sharing channel,PDSCH)、物理下行控制信道(physical downlink control channel,PDCCH)、或物理广播信道(physical broadcast channel,PBCH)等)。
还例如,天线面板可以通过波束,QCL,TCI-state,spatial relation或配置在QCL,TCI-state,spatial relation中的某个index来表征。天线面板也可以通过波束组,QCL组,TCI-state组,spatial relation组等来表征。天线面板也可以通过终端设备上报的终端能力参数集合来表征。终端能力参数集合与天线面板存在对应关系。一个终端能力参数集合包括一个天线面板对应的相关终端能力,例如,包括一个天线面板对应的最大传输层数,最大SRS端口数,最大传输功率等。
4、能力参数集合:也可以称为能力值集合(capability value set)或能力值(capability values),表达的是相同含义。针对终端设备可能有多个天线面板,若终端设备发生旋转等,终端设备需要一种机制上报网络设备发生了天线面板切换。由于终端厂商不希望直接向网络设备暴露天线面板,或由网络设备控制终端设备的天线面板,提出了能力值集合。它是一个逻辑的概念,当前协议中其内容是一个能力,即终端设备支持的最大的SRS端口数。可以理解为,若终端设备的多个天线面板都具有相同的支持的SRS端口数,则对应相同的能力值标识(capability value identifier,capability value ID)。在终端设备上报L1测量结果时,可以对每个测量结果包括一个能力值标识。若终端设备前后针对某个参考信号的测量结果关联了不同的能力值标识(即关联不同的SRS端口数),则网络设备可以意识到终端设备是采用了不同的天线面板进行测量。在未来版本的协议演进中,能力值集合可能还会进一步包括更多的内容,本申请实施例对此不作限定。
5G可以采用高频通信,即采用高频段信号传输数据。高频通信的一个主要问题是信号能量随传输距离急剧下降,导致信号传输距离短。为了克服这个问题,高频通信采用模拟波束技术,通过对天线阵列进行加权处理,将信号能量集中在一个较小的角度范围内,形成一个类似于光束一样的信号(称为模拟波束,简称波束),从而提高传输距离。网络设备和终端设备都要采用波束进行传输。
在进行上下行数据传输时,网络设备和终端设备需要采用特定的波束来进行。具体采用哪个波束来进行传输是通过波束测量过程来确定的。网络设备通过高层信令为终端设备配置多个波束测量参考资源,每个资源对应一个测量信号。对于每个资源,网络设备通过一个波束发送该资源对应的测量信号,终端设备测量各个波束发送的测量信号,来确定该波束(资源)的质量,如RSRP。通过测量各个波束的RSRP,终端设备选择一个或多个RSRP最大的资源,并将其资源的索引和相应的RSRP上报给网络设备。网络设备再从中选择一个或多个资源(波束),用于数据传输。对于每个发送波束,终端设备还会确定一个最佳接收波束,用于接收该发送波束上的信号。接收波束的确定也是通过测量过程来确定的,与本申请关系较小,此处不再赘述。每个发送波束对应的接收波束可能是不相同的。
天线阵列也称为天线面板。每个天线面板上有多个天线,该多个天线组成天线阵列,可以生成指向特定方向的波束。一个天线面板一般可以生成多个不同方向的波束,但同一时间只能生成其中一个。一个天线面板生成的多个波束的指向主要集中在该天线面板所朝向的方向,其他方向(如天线面板的背向)无法生成有效的波束。因此,终端设备一般需要配备多个天线面板,来满足各个方向的波束覆盖。
图1是本申请实施例提供的天线面板的示意图。如图1所示,该终端设备配备了两个天线面板,分别为天线面板#1和天线面板#2,每个天线面板朝向不同的方向,每个天线面板可以生成多个不同方向的波束,从而构成较为全面的波束覆盖。
终端设备可以采用一个或一组波束进行上行传输。采用一组波束时,该一组波束可以位于不同的天线面板上,即通过多个天线面板上的各一个波束进行上行传输,各波束可以同时传输,也可以分时传输。一组波束也可以位于同一个天线面板,但这时该组波束中的各个波束只能进行分时传输,因为一个天线面板在同一时间只能生成一个波束,无法同时采用多个波束进行传输。
图2是本申请实施例提供的通信系统的系统架构示意图。如图2中的a)所示,该通信系统包括网络设备210、终端设备220和终端设备230,其中,终端设备220和终端设备230可以是移动的或固定的。网络设备210可以为基站、或TRP、或其他类型的网络设备,本申请实施例对此不作限定。网络设备210可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域(小区)内的终端设备220和终端设备230进行无线链路通信,也即,单个网络设备可以与一个或多个终端设备进行无线链路通信。如图2中的b)所示,该通信系统包括网络设备240、网络设备250和终端设备260,其中,终端设备260可以是移动的或固定的。网络设备240和网络设备250可以为基站、TRP、或其他类型的网络设备,本申请实施例对此不作限定。网络设备240和网络设备250可以同时与终端设备260进行无线链路通信,也即多个网络设备可以同时与某个终端设备进行无线链路通信。
可选地,图2所示的通信系统还可以包括更多的网络设备,以及每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
在图2所示的通信系统中,终端设备与网络设备的通信涉及TA机制,TA机制的主要目的是保证系统中的上行信号同时到达基站,避免干扰。目前,针对每个服务小区,终端设备只维护一个TA,终端设备可以配置一组服务小区,其中具有相同上行定时或者相同TA的服务小区在相同的TAG。终端设备可以上报支持的最大TAG的数量。但是在多TRP场景中,如果相同服务小区的不同站点距离较远,终端设备可能需要在一个服务小区维护 多个TA来保证每个TRP上行传输的定时同步,还可能存在一个TRP在非服务小区,终端设备可能还需要维护非服务小区的TA,而终端设备仅上报支持的最大TAG数,网络设备无法合理地对终端设备进行上行传输调度。
为解决上述问题,本申请提供了一种通信方法,终端设备根据接收来自网络设备的多个参考信号所使用的天线面板,确定第一资源组对应的多TA同传能力,也即,确定接收多个参考信号所使用的天线面板是否支持同时使用多个TA发送上行信号,并将第一资源组对应的多TA同传能力上报给网络设备,以便于网络设备参考该信息,为终端设备进行上行传输调度,这样一来,有利于提高网络设备对终端设备进行上行传输调度的合理性。
下文将结合附图,详细描述本申请提供的通信方法。
应理解,下文示出的实施例虽然以终端设备和网络设备交互为例来描述,但不应对该方法的执行主体构成任何限定。只要能够通过运行记录有本申请实施例提供的方法的代码的程序,便可执行本申请实施例提供的方法。例如,终端设备也可以替换为配置在终端设备中的部件(如,芯片、芯片系统等),或其他能够调用程序并执行程序的功能模块,网络设备也可以替换为配置在网络设备中的部件(如,芯片、芯片系统等),或其他能够调用程序并执行程序的功能模块。本申请实施例对此不作限定。
图3是本申请实施例提供的通信方法的示意性流程图。图3所示的方法300可以包括S310至S340。下面将详细描述图3中的各个步骤。
S310、网络设备向终端设备发送多个参考信号。相应地,终端设备接收来自网络设备的多个参考信号。
上述多个参考下信号承载于第一资源组中,第一资源组包括多个参考信号资源,且多个参考信号资源中的任意两个参考信号资源来自网络设备配置的不同的参考信号资源集合。
示例性地,网络设备给终端设备配置X个参考信号资源集合,X为正整数,每个参考信号资源集合对应一个TRP,每个参考信号资源集合包括一个或多个参考信号资源,不同参考信号资源集合中的参考信号资源数可以相同或不同,网络设备可以基于上述X个参考信号资源集合中的参考信号资源给终端设备发送参考信号,相应地,终端设备接收到来自网络设备的参考信号,并对其进行测量,确定需要上报的M个资源组,每个资源组中的任意两个参考信号资源来自不同的参考信号资源集合。其中,M可以是网络设备配置的,也就是说,网络设备可以给终端设备配置需要上报资源组的数量。第一资源组为M个资源组中的一个资源组。
例如,网络设备配置2个参考信号资源集合,分别为参考信号资源集合#1和参考信号资源集合#2,参考信号资源集合#1对应TRP#1,参考信号资源集合#2对应TRP#2,参考信号资源集合#1中包括5个参考信号资源,这5个参考信号资源所对应5个参考信号资源索引分别为#1至#5,参考信号资源集合#2中包括7个参考信号资源,这7个参考信号资源所对应7个参考信号资源索引分别为#1至#7,网络设备基于上述参考信号资源给终端设备发送参考信号以及参数M,假设M=4,终端设备接收到来自网络设备的参考信号后,对其进行测量,并确定出4个资源组,分别为资源组#1、资源组#2、资源组#3、资源组#4,其中,每个资源组中包括一个来自参考信号资源集合#1中的参考信号资源和一个来自参考信号资源集合#2中的参考信号资源,例如,资源组#1中包括参考信号资源集合#1的参考 信号资源#1和参考信号资源集合#2的参考信号资源#5,第一资源组是上述4个资源组中的一个。
S320、终端设备根据接收第一资源组的多个参考信号所使用的天线面板,确定第一资源组对应的多TA同传能力。
其中,第一资源组对应的多TA同传能力用于指示终端设备接收第一资源组的多个参考信号所使用的天线面板是否支持同时使用多个TA发送上行信号。
一种可能的实现方式是,终端设备接收第一资源组的多个参考信号,每个参考信号对应一个基站发送波束,若终端设备使用一个天线面板接收,则确定终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号;若终端设备使用多个天线面板接收,但多个天线面板共用一个数字射频链路,则终端设备无法同时使用多个不同的上行发送定时在多个面板上发送信号,则确定终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号;若终端设备使用多个天线面板接收,且多个天线面板连接于不同的数字射频链路,也即多个天线面板是相互独立的,则确定终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号。
例如,终端设备的天线面板包括天线面板#1和天线面板#2。终端设备在接收第一资源组对应的多个参考信号时,都使用天线面板#1接收,则确定终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号。若终端设备使用天线面板#1和天线面板#2接收,且天线面板#1和天线面板#2连接于不同的数字射频链路,也即,天线面板#1和天线面板#2是独立的,则确定终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号;若天线面板#1和天线面板#2连接于同一数字射频链路,则确定终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号。
S330、终端设备向网络设备发送第一指示信息和第二指示信息。相应地,网络设备接收来自终端设备的第一指示信息和第二指示信息。
第一指示信息用于指示第一资源组中所有参考信号资源的索引,第二指示信息用于指示第一资源组对应的多TA同传能力。
第一资源组对应的多TA同传能力可以通过以下任一种方式来指示:
方式一,第二指示信息包括用于指示第一资源组对应的多TA同传能力的指示比特,也即第一资源组对应的多TA同传能力可以通过指示比特来指示,换言之,该指示比特指示终端设备接收第一资源组的多个参考信号所使用的天线面板是否支持同时使用多个TA发送上行信号。示例性地,1比特(bit)字段用于指示第一资源组对应的多TA同传能力。例如,当该bit为1时,表示终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号;当该bit为0时,表示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号。
方式二,第二指示信息包括能力参数集索引,也即第一资源组对应的多TA同传能力可以通过能力参数集索引来指示,该能力参数集索引关联第一资源组对应的能力参数集,能力参数集中包括第一资源组对应的多TA同传能力。示例性地,终端设备可以上报能力参数集索引,该能力参数集索引关联第一资源组对应的能力参数集,能力参数集中包括第 一资源组对应的多TA同传能力。可选地,能力参数集中还可以包括第一资源组对应的一个或多个天线面板中每个天线面板支持的最大SRS端口数、第一资源组对应的天线面板数等。
可以理解,终端设备确定多个资源组的情况下,终端设备可以向网络设备发送与M个资源组一一对应的M个指示信息和与M个资源组中的N个资源组一一对应的N个指示信息,其中,M个指示信息中的每个指示信息用于指示M个资源组中的一个资源组中所有参考信号资源的索引,N个指示信息中的每个指示信息用于指示N个资源组中一个资源组对应的多TA同传能力,M个指示信息包括上述第一指示信息,N个指示信息包括上述第二指示信息,0≤N≤M,N为整数。
示例性地,网络设备配置M=2,终端设备确定2个资源组,则可以将上述2个资源组中的资源的索引及其对应的测量结果上报给网络设备,同时,可以将上述2个资源组中某一个资源组对应的多TA同传能力上报给网络设备,以便于网络设备参考上述信息,对终端设备进行上行传输调度。
可选地,N是由网络设备配置的,或,N为预定义的。
一种可能的设计是,N是由网络设备配置的。示例性地,网络设备可以给终端设备发送配置信息,该配置信息用于配置上报多TA同传能力的资源组的数量N。
另一种可能的设计是,上述N是预定义的。例如,协议预先规定好N=M,也即上报多TA同传能力的资源组的数量等于M。又例如,协议预先规定好N等于终端设备最大支持上报的多TA同传能力的资源组的数量和M之间的较小值。
可选地,上述N个资源组是M个资源组中的前N个,或,N个资源组是由终端设备从M个资源组中确定的。其中,N个资源组是M个资源组中的前N个是指终端设备上报的M个资源组中排序为前N个的N个资源组。
一种可能的设计是,终端设备上报的M个资源组中的前N个资源组依次对应这N个资源组中每个资源组对应的多TA同传能力。
另一种可能的设计是,终端设备从M个资源组中确定出N个资源组,上报该N个资源组中每个资源组对应的多TA同传能力。示例性地,终端设备上报多个多TA同传能力信息,每个多TA同传能力信息中包含一个资源组索引,用于指示该多TA同传能力信息对应哪个资源组。该信息的字段长度可根据M和N的大小关系来确定。例如,当N<M时,该字段长度为log2M向上取整;当N=M时,该字段长度为0,这时上报的N=M组多TA同传能力信息与M个资源组一一对应,不需要具体指示。
下面将结合表1和表2详细描述终端设备上报的M个资源组的资源索引以及N个资源组的多TA同传能力。其中,表1中所示的资源组对应的多TA同传能力通过指示比特来指示,表2中所示的资源组对应的多TA同传能力通过能力参数集索引来指示。
如表1所示,终端设备确定的资源组的数量M为2,支持上报多TA同传能力的资源组的数量N为2,可以看出,终端设备上报的资源索引包括资源组#1的资源索引#1(CRI#1 of 1st resource group)、资源组#1的资源索引#2(CRI#2 of 1st resource group)、资源组#2的资源索引#1(CRI#1 of 2nd resource group)和资源组#2的资源索引#2(CRI#2 of 2nd resource group),终端设备上报的多TA同传能力通过指示比特来指示,包括资源组#1对应的多TA同传能力(TwoTAsSimultaneous for 1st resource group)、资源组#2对应的多TA 同传能力(TwoTAsSimultaneous for 2nd resource group)。可以看出,表1中还可能包括终端设备测量的参考信号的RSRP,以及能力参数集的ID(capability value set ID)。其中每个能力参数集索引对应的能力参数集中包含接收资源组中对应的其中一个参考信号所使用的面板对应的最大SRS端口。网络设备可以参考表1所示的信息,对终端设备进行上行传输调度。
表1
如表2所示,终端设备向网络设备上报的资源索引包括资源组#1的资源索引#1(CRI#1 of 1st resource group)、资源组#1的资源索引#2(CRI#2 of 1st resource group)、资源组#2的资源索引#1(CRI#1 of 2nd resource group)和资源组#2的资源索引#2(CRI#2 of 2nd resource group),终端设备上报的第二指示信息包括资源组#1对应的能力参数集索引(capability value set ID for 1st resource group)、资源组#2对应的能力参数集索引(capability value set ID for 1st resource group)。其中能力参数集索引对应的能力参数集包括资源组对应的多TA同传能力,还可能包括接收资源组中对应的所有参考信号所使用的一个或多个面板对应的最大SRS端口数、资源组对应的天线面板数等。可以看出,表2中还可以包括终端设备测量的参考信号的RSRP。
表2
前已述及,第一资源组对应的多TA同传能力用于指示终端设备接收第一资源组的多个参考信号所使用的天线面板是否支持同时使用多个TA发送上行信号。一种情况是,第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号;另一种情况是,第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号。下面将对上述两种情况进行详细描述。
若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号,则终端设备可以使用第一资源组关联的一个或多个TA在第一资源组对应的天线面板上同时或分时发送上行信号。
若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联一个TA,另外,终端设备接收第一资源组的多个参考信号所使用的天线面板为多个,则终端设备可以使用第一资源组关联的一个TA在第一资源组对应的天线面板上同时发送上行信号。
若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联一个TA,另外,终端设备接收第一资源组的多个参考信号所使用的天线面板为一个,则终端设备可以使用第一资源组关联的一个TA在第一资源组对应的天线面板上分时发送上行信号。
若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联多个TA,另外,终端设备接收第一资源组的多个参考信号所使用的天线面板为多个,则终端设备可以使用一个目标TA在第一资源组对应的天线面板上同时发送上行信号。
若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联多个TA,另外,终端设备接收第一资源组的多个参考信号所使用的天线面板为一个,则终端设备可以使用第一资源组关联的多TA在第一资源组对应的天线面板上分时发送上行信号。
应理解,在本申请实施例中,终端设备在第一资源组对应的天线面板上同时发送上行信号时,第一资源组对应的天线面板的个数为多个,也即终端设备接收第一资源组的多个参考信号所使用的天线面板个数为多个,换言之,网络设备在确定第一资源组对应的天线面板的个数为多个的情况下,才有可能调度终端设备在第一资源组对应的天线面板上同时发送上行信号,或者说,调度终端设备进行同传。
还应理解,上述终端设备接收第一资源组的多个参考信号所使用的天线面板个数,网络设备可以通过终端上报第一资源组对应的能力参数集索引对应的能力参数集确定。终端设备具体使用上面多种方式中的哪一种方式进行上行传输,还需要网络设备来调度,下面将结合步骤S340,详细描述网络设备对终端设备进行上行传输调度的过程。
S340、网络设备基于第一指示信息和第二指示信息,对终端设备进行上行传输调度。
一种可能的设计是,网络设备可以调度终端设备使用参考第一资源组的上行发送波束进行上行时分传输,例如,网络可以通过下行控制信息(downlink control information,DCI)或MAC控制元素(control element,CE)指示终端设备的上行发送波束参考第一资源组中的参考信号,终端设备可以使用第一资源组关联的一个或多个TA在接收第一资源组的参考信号对应的一个或多个面板进行时分传输,分时发送所使用的第一资源组关联的TA可以相同或不同。
另一种可能的设计是,网络设备调度终端设备使用参考第一资源组的上行发送波束进行同传。示例性地,若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板支持同时使用多个TA发送上行信号,则网络设备可以调度终端设备使用第一资源组中的参考信号的上行发送波束同时发送上行信号,终端设备就 可以在第一资源组对应的天线面板上使用一个或多个TA同时发送上行信号,也即网络设备调度终端设备进行多TA同传。若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联一个TA,若终端接收第一资源组的参考信号对应多个面板,则终端设备可以使用第一资源组关联的一个TA在第一资源组对应的天线面板上同时发送上行信号。
若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联多个TA,若终端接收第一资源组的参考信号对应多个面板,则终端设备可以使用一个目标TA在第一资源组对应的天线面板上同时发送上行信号。
可选地,上述目标TA可以由以下任意一种方式确定:
第一种方式,上述目标TA是由网络设备指示的。示例性地,网络设备接收来自终端设备的第一资源组对应的多TA同传能力,若第一资源组对应的多TA同传能力指示终端设备接收第一资源组的多个参考信号所使用的天线面板不支持同时使用多个TA发送上行信号,但第一资源组关联多个TA,且网络设备调度终端设备使用参考第一资源组的上行发送波束进行同传,则网络设备给终端设备发送第三指示信息,该第三指示信息用于指示终端设备发送上行信号所使用的目标TA。其中,第三指示信息的几种可能的设计如下:
设计a,第三指示信息包括第一资源组关联的多个TA中的任意一个TA的索引,也即,目标TA为第一资源组关联的多个TA中的任意一个,终端设备可以基于TA的索引,确定出目标TA,并使用目标TA在第一资源组对应的天线面板上同时发送上行信号。
