Description
相关申请的交叉引用
本申请主张在2020年7月9日在中国提交的中国专利申请号No.202010658814.X的优先权,其全部内容通过引用包含于此。
本申请涉及通信技术领域,尤其涉及一种波束报告的发送方法、装置及电子设备。
对于具有多个天线面板(antenna panel)的用户终端(User Equipment,UE),此类UE的能力可能仅支持激活一个天线面板,或者可能支持同时激活多个天线面板。但是,为了节能,对于支持同时激活多个天线面板的UE,也可以仅激活一个天线面板与网络通信。
当UE在使用多个天线面板做波束测量之后向网络发送波束报告时,在波束报告(beam report)中所携带的同步信号块资源指示(SSB Resource Indicator,SSBRI)和/或信道状态信息参考信号资源指示(CSI-RS resource indicator,CRI)可能对应着不同天线面板所测量得到的性能较优的波束,此时如果在beam report中增加各SSBRI和/或CRI对应的天线面板信息,如天线面板标识(panel ID),将会增加上报的信令开销;如果不携带天线面板信息,那么网络将无法获知beam report中的SSBRI和/或CRI与UE天线面板的对应关系。当UE在后续的数据传输时为了省电而仅激活一个天线面板时,若网络在调度信道时指示的波束信息恰恰是根据UE当前未激活天线面板所测量并上报的SSBRI和/或CRI得到的时,UE需要较大的时延做天线面板切换,即将当前天线面板去激活,并将另一个天线面板激活,但网络调度信道的时间偏移可能不足以满足天线面板切换的时延需求,导致网络和UE间的数据传输中断。

请参见图1,图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备,需要说明的是,在本申请实施例中并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,其中,上述基站可以是5G及以后版本的基站(例如:gNB、5G NR NB等),或者其他通信系统中的基站(例如:eNB、WLAN接入点、或其他接入点等),或者为位置服务器(例如:E-SMLC或LMF(Location Manager Function)),其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是本申请实施例并不限定基站的具体类型和具体通信系统。
长期演进(Long Term Evolution,LTE)/演进的长期演进(LTE-Advanced,LTE-A)等无线接入技术标准都是以多输入多输出(multiple-in multipleout,MIMO)+正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)技术为基础构建起来的。其中,MIMO技术利用多天线系统所能获得的空间自由度,来提高峰值速率与系统频谱利用率。
MIMO技术的维度不断扩展,一些通信协议中,最多可以支持4层的 MIMO传输。在增强MU-MIMO技术中,传输模式(Transmission Mode,TM)-8的多用户多输入多输出(Multi-User MIMO,MU-MIMO)传输中最多可以支持4个下行数据层。一些通信协议中,可以将单用户多输入多输出(Single-User MIMO,SU-MIMO)的传输能力扩展至最多8个数据层。
MIMO技术正向着三维化和大规模化的方向推进。大规模(massive)MIMO技术使用大规模天线阵列,能够极大地提升系统频带利用效率,支持更大数量的接入用户。因此massive MIMO技术为下一代移动通信系统中最有潜力的物理层技术之一。
在massive MIMO技术中如果采用全数字阵列,可以实现最大化的空间分辨率以及最优MU-MIMO性能,但是这种结构需要大量的模数/数模(AD/DA)转换器件以及大量完整的射频-基带处理通道,无论是设备成本还是基带处理复杂度都将是巨大的负担。
为了避免上述的实现成本与设备复杂度,数模混合波束赋形技术应运而生,即在传统的数字域波束赋形基础上,在靠近天线系统的前端,在射频信号上增加一级波束赋形。模拟赋形能够通过较为简单的方式,使发送信号与信道实现较为粗略的匹配。模拟赋形后形成的等效信道的维度小于实际的天线数量,因此其后所需的AD/DA转换器件、数字通道数以及相应的基带处理复杂度都可以大为降低。模拟赋形部分残余的干扰可以在数字域再进行一次处理,从而保证MU-MIMO传输的质量。相对于全数字赋形而言,数模混合波束赋形是性能与复杂度的一种折中方案,在高频段大带宽或天线数量很大的系统中具有较高的实用前景。
在对4G以后的下一代通信系统研究中,将系统支持的工作频段提升至6GHz以上,最高约达100GHz。高频段具有较为丰富的空闲频率资源,可以为数据传输提供更大的吞吐量。高频信号的波长短,同低频段相比,能够在同样大小的天线面板上布置更多的天线阵元,利用波束赋形技术形成指向性更强、波瓣更窄的波束。因此,将大规模天线和高频通信相结合,也是未来的趋势之一。
模拟波束赋形是全带宽发射的,并且每个高频天线阵列的天线面板上每个极化方向阵元仅能以时分复用的方式发送模拟波束。模拟波束的赋形权值 是通过调整射频前端移相器等设备的参数来实现。
目前,通常是使用轮询的方式进行模拟波束赋形向量的训练,即每个天线面板每个极化方向的阵元以时分复用方式依次在约定时间发送训练信号(即候选的赋形向量),终端经过测量后反馈波束报告,供网络侧在下一次传输业务时采用该训练信号来实现模拟波束发射。波束报告的内容通常包括最优的若干个发射波束标识及其对应的接收功率或信干噪比。
在做波束测量(beam measurement)时,网络会配置参考信号资源集合(RS resource set),其中包括至少一个参考信号资源,例如SSB resource或CSI-RS resource。UE测量每个RS resource的L1-RSRP/L1-SINR,并将最优的至少一个测量结果上报给网络,上报内容包括SSBRI或CRI、及对应的L1-RSRP/L1-SINR。该报告内容反映了至少一个最优的波束及其质量,供网络确定用来与UE传输信道或信号的波束信息。
在经过波束测量和波束报告后,网络可以对下行与上行链路的信道或参考信号做波束指示(beam indication),用于网络与UE之间建立波束链路,实现信道或参考信号的传输。
对于PDCCH的波束指示,网络使用无线资源控制(Radio Resource Control,RRC)信令为每个CORESET配置K个传输配置指示(Transmission Configuration Indication,TCI)state,当K>1时,由媒体介入控制控制元素(MAC CE)指示或激活1个TCI state,当K=1时,不需要额外的MAC CE命令。UE在监听PDCCH时,对CORESET内全部搜索空间(search space)使用相同准共址(Quasi-colocation,QCL)信息,即使用相同的TCI state来监听PDCCH。该TCI状态中的源参考信号(referenceSignal)(例如周期CSI-RS resource、半持续CSI-RS resource、SS block等)与UE-specific PDCCH解调参考信号(Demodulation Reference Signal,DMRS)端口是空间QCL的。UE根据该TCI状态即可获知使用哪个接收波束来接收PDCCH。
对于PDSCH的波束指示,网络通过RRC信令配置M个TCI state,再使用MAC CE命令激活2
N个TCI state,然后通过下行控制信息(Downlink Control Information,DCI)的N-bit TCI field来通知TCI状态,该TCI状态中的referenceSignal与要调度的PDSCH的DMRS端口是QCL的。UE根据该 TCI状态即可获知使用哪个接收波束来接收PDSCH。
对于CSI-RS的波束指示,当CSI-RS类型为周期CSI-RS时,网络通过RRC信令为CSI-RS resource配置QCL信息。当CSI-RS类型为半持续CSI-RS时,网络通过MAC CE命令来从RRC配置的CSI-RS resource set中激活一个CSI-RS resource时指示其QCL信息。当CSI-RS类型为非周期CSI-RS时,网络通过RRC信令为CSI-RS resource配置QCL,并使用DCI来触发CSI-RS。
对于物理上行控制信道(Physical Uplink Control Channel,PUCCH)的波束指示,网络使用RRC信令通过参数PUCCH-SpatialRelationInfo为每个PUCCH resource配置空间关系信息(spatial relation information),当为PUCCH resource配置的spatial relation information包含多个时,使用MAC-CE激活其中一个spatial relation information。当为PUCCH resource配置的spatial relation information只包含1个时,不需要额外的MAC CE命令。
对于物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的波束指示,PUSCH的spatial relation信息是当PDCCH承载的DCI调度PUSCH时,DCI中的探测参考信号资源指示(SRS resource indicator,SRI)域(field)的每个SRI代码点(codepoint)指示一个SRI,该SRI用于指示PUSCH的spatial relation information。
对于探测参考信号(Sounding Reference Signal,SRS)的波束指示,当SRS类型为周期SRS时,网络通过RRC信令为SRS resource配置spatial relation information。当SRS类型为半持续SRS时,网络通过MAC CE命令来从RRC配置的一组spatial relation information中激活一个。当SRS类型为非周期SRS时,网络通过RRC信令为SRS resource配置spatial relation information,还可以使用MAC CE命令更新非周期SRS resource的spaital relation information。
在multi-TRP场景,根据控制信息的发送方式,可以区分为single DCI和multi-DCI,前者是在一个发送接收点(TRP)发送DCI来调度多个TRP上的数据传输,后者是允许在多个TRP发送DCI来分别调度在各自TRP上的数据传输。
在DCI调度PDSCH时,当DCI与PDSCH之间的调度间隔(scheduling offset,或称time offset)小于或等于预设门限时,需要使用默认波束来传输PDSCH。
一般地,控制信道(如物理下行控制信道(Physical Downlink Control Channel,PDCCH))的波束较宽,是为了保证覆盖,而业务信道(如物理下行共享信道(Physical Downlink Shared Channel,PDSCH))的波束较窄,是为了提高接收信噪比,以及获得更优的数据速率和吞吐量。但是网络在使用参考信号资源(RS resource)供UE测量波束质量时,UE仅根据测量RS resource所得的层1-参考信号接收功率(Layer1-Reference Signal Receiving Power,L1-RSRP)或层1-信号与干扰加噪声比(Layer1-Signal to Interference plus Noise Ratio,L1-SINR)来选择质量较优的波束时,很可能由于宽波束的波束质量不如窄波束,那么在波束测量过程中网络使用宽波束发送的RS resource将无法被UE在beam report中上报,网络也就不易根据beam report中的SSBRI和/或CRI获知使用哪些波束来传输控制信道,也就是说不能获知传输控制信道所预期使用的宽波束信息。。
其中,上述所提及的波束信息,也可以称为:波束信息、空间关系(spatial relation)信息、空域发送滤波器(spatial domain transmission filter)信息、空域滤波器(spatial filter)信息、传输配置指示状态(TCI state)信息、准共址(QCL)信息或QCL参数等。其中,下行波束信息通常可使用TCI state信息或QCL信息表示。上行波束信息通常可使用spatial relation信息表示。
所提及的天线面板,也可以称为:天线组、天线端口组、天线集合、天线端口集合、波束集合、波束子集合、天线阵列、天线端口阵列、天线子阵列、天线端口子阵列、逻辑实体、实体或天线实体等。
波束报告,也就是信道状态信息(Channel State Information,CSI)report配置信息中的参数reportQuantity被设置为cri-RSRP、ssb-Index-RSRP、csi-SINR、ssb-Index-SINR。或者,波束报告也可称之为L1-RSRP报告、L1-SINR报告。

一具体实施例中,假设UE有两个panel,当前UE仅激活了panel1,而 panel2处于未激活状态。网络侧设备配置了CSI-ReportConfig中包含了reportConfigId为A,且包含了与其关联的另一个reportConfigId为B。CSI-ReportConfig所对应的CSI-RS resource为非周期的。
网络侧设备使用DCI触发CSI-RS resource set,网络侧设备在发送各CSI-RS resource时使用宽波束。其中触发(trigger)offset小于UE上报的预设门限,则UE使用panel1上的接收波束来测量CSI-RS resource set中的各CSI-RS resource的L1-RSRP,UE根据reportConfigId为A的CSI-ReportConfig,将较优的至少一个CRI+L1-RSRP上报给网络侧设备。
网络侧设备又使用DCI触发CSI-RS resource set,网络侧设备在发送各CSI-RS resource时使用窄波束。其中trigger offset也小于UE上报的预设门限,则UE仍使用panel1上的接收波束测量该CSI-RS resource set中的各CSI-RS resource的L1-RSRP,UE根据reportConfigId为B的CSI-ReportConfig,将较优的至少一个CRI+L1-RSRP上报给网络侧设备。
网络侧设备根据关联关系,可知上述两个波束报告是UE使用同一个panel测量所得,则网络侧设备可根据前一个波束报告确定控制信道(PDCCH)的QCL信息,如将前一个波束报告中的CRI和/或SSBRI所对应的CSI-RS resource或SSB resource作为控制信道的QCL source,也就是说控制信道使用宽波束。网络侧设备还可以根据后一个波束报告确定业务信道(PDSCH)的QCL信息,如将后一个波束报告中的CRI和/或SSBRI所对应的CSI-RS resource或SSB resource作为控制信道的QCL source,也就是说数据信道使用窄波束。
同理,网络侧设备还可以配置reportConfigId为C和D的相关联的波束报告,网络侧设备在触发这两个波束报告对应的非周期CSI-RS resource set时,其中的trigger offset大于UE上报的预设门限,则UE可开启或激活panel2,使用panel2上的接收波束测量CSI-RS resource set中的各CSI-RS resource的L1-RSRP,UE根据reportConfigId为C和D的CSI-ReportConfig,上报两个波束报告,其中一个波束报告是宽波束的测量结果,另一个波束报告是窄波束的测量结果。网络侧设备据此可知,根据两个相关联的波束报告确定控制信道和数据信道的QCL信息。
