Description

准共址关系指示方法、设备及存储介质 技术领域
本申请涉及通信技术，尤其涉及一种准共址关系指示方法、设备及存储介质。
背景技术
在5G新空口(New Radio，NR)中，增加了传输配置指示(Transmission Configuration Indicator，TCI)的架构设计，用以指示一个数据或控制信道的解调信号和一个或多个参考信号的准共址关系(Quasi Co-Location，QCL)。
5G协议规定了多种类型的准共址关系，分别表示不同的信道参数类型。例如，如果采用的准共址的类型为type-D，则表明一个数据或控制信道和另一个参考信号采用同一个波束发射。为了实现不同信道的准共址配置的功能，一些实现中需要在不同信道的配置(configure)参数里配置TCI列表，这不仅增加的信息配置的冗余度，同时增加了指示配置的复杂程度。

虽然上述以LTE系统为例进行了介绍，但本领域技术人员应当知晓，本申请不仅仅适用于LTE系统，也可以适用于其他无线通信系统，例如GSM、CDMA2000、WCDMA、TD-SCDMA以及未来新的网络系统等，此处不做限定。
基于上述移动终端硬件结构以及通信网络系统，提出本申请各个实施例。
首先对本申请一种适用的应用场景进行介绍。
图3为本申请实施例提供的一种应用场景示意图。请参见图3，网络设备301和终端设备302之间可以进行无线通信，从而实现数据传输。可选地，终端设备302可以是图1中的移动终端或图2中的UE；网络设备301可以是图2中除UE以外的其它设备例如基站eNodeB。
本申请实施例的技术方案可应用于NR通信技术中，NR是指新一代无线接入网络技术，可以应用在未来演进网络，如第五代移动通信(the 5th Generation Mobile Communication，5G)系统中。本申请实施例中的方案还可以应用于无线保真(Wireless Fidelity，WIFI)和长期演进(Long Term Evolution，LTE)等其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，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，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
在5G通信中，由于需要采用基于波束的传输方式，因此增加了TCI的架构设计，TCI 可以指示数据与参考信号的准共址关系。
可选地，参考信号可以包括由同步信号(Synchronization Signal，SS)和物理广播信道(Physical Broadcasting Channel，PBCH)共同构成的SSB(Synchronization Signal and PBCH block，同步信号和PBCH块)等。可选地，同步信号可以包括主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)等。
准共址关系包括多种类型，具体可以分为Type-A QCL、Type-B QCL、Type-C QCL、Type-D QCL四个类型，用于表示多普勒频移(Doppler Shift)、多普勒频散(Doppler Spread)、平均延迟时间(Average Delay)、延迟扩展(Delay Spread)与空间接收波束参数(Spatial Rx Parameter)的不同组合或选择。
可选地，Type-D类型的准共址，表明数据可以和参考信号采用同一个波束发射，接收端即可采用相应的接收滤波器。因此，可以通过配置TCI来指示数据和参考信号对应的波束配对关系。
在一些技术中，物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行共享信道(Physical Downlink Share Channel，PDSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、物理上行共享信道(Physical Uplink Share Channel，PUSCH)和分别采用各自的TCI指示架构，用来指示QCI的TCI状态列表(TCI-state list)，分别放在PDCCH配置(PDCCH-configure)、PDSCH配置(PDSCH-configure)、PUCCH配置(PUCCH-configure)、PUSCH配置(PUSCH-configure)中。可以通过高层信令为PDCCH、PDSCH、PUCCH、PUSCH等配置TCI状态。
图4为本申请实施例提供的一种信道与参考信号准共址的原理示意图。如图4所示，以信道PDCCH、PDSCH与参考信号准共址为例，PDCCH配置和PDSCH配置中均可以包括TCI状态列表。可选地，PDCCH配置中的多个TCI状态ID：ni、nj、nk，映射到PDSCH配置中的TCI状态ID：ni、nj、nk，并与多个参考信号Si、Sj、Sk具有对应关系。
如图所示，ni对应于与参考信号Si准共址，nj对应于与参考信号Sj准共址，nk对应于参考信号Sk准共址。可以通过高层配置来指示使用哪一TCI状态ID即与哪一参考信号准共址。当指示PDCCH或PDSCH与任一参考信号准共址时，可以通过所述参考信号对应的波束进行PDCCH或PDSCH的传输。
例如，当指示PDCCH或PDSCH与参考信号Si准共址，那么，可以采用参考信号Si对应的波束进行PDCCH或PDSCH的传输。
在上述设计中，不同信道的TCI状态列表配置在各自的配置参数里，当TCI状态列表发生变化时，每个信道都需要改变配置，这会增加波束管理过程中的指示配置的复杂程度，使得系统效率较低。因此，为了简化波束管理流程，需要设计一种TCI架构用来统一管理所有信道的TCI指示。
有鉴于此，本申请实施例提供一种准共址关系指示方法，可以根据上行参考信号和/或下行参考信号的波束集合确定一个统一的TCI池，并根据所述TCI池来指示准共址关系，无需在每一个信道中均配置相应的TCI状态列表，简化配置复杂度，提高系统效率。
下面以具体的实施例对本申请实施例的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请实施例的实施例进行描述。
图5为本申请实施例提供的一种准共址关系指示方法的流程示意图。本实施例中方法的执行主体可以为网络设备。如图5所示，该方法可以包括：
步骤501、根据上行参考信号和/或下行参考信号的波束集合确定TCI池。
可选地，所述TCI池可以称为TCI Configure Pool，用于保存参考信号对应的波束集合。所述参考信号可以包括上行参考信号和/或下行参考信号。
本申请实施例中所述的上行可以是指终端设备向网络设备发送，下行可以是指网络设备向终端设备发送。对应的，上行参考信号可以是指终端设备向网络设备发送的参考信号，下行参考信号可以是指网络设备向终端设备发送的参考信号。
信号的发送和接收可以基于波束来实现。不同的参考信号可以基于不同的波束来传输，当参考信号有多个时，多个参考信号对应的波束可以形成波束集合，通过波束集合可以确定TCI池。
可选地，所述TCI池中可以包括至少一个上行参考信号的波束集合，或者，可以包括至少一个下行参考信号的波束集合，或者，也可以包括至少一个上行参考信号的波束集合和至少一个下行参考信号的波束集合。
步骤502、根据所述TCI池，发送TCI指示信息，所述TCI指示信息用于指示数据和参考信号的准共址关系。
可选地，所述数据可以包括上行数据和/或下行数据。可选地，上行数据可以为终端设备发送给网络设备的数据，下行数据可以为网络设备发送给终端设备的数据。
可选地，所述上行数据可以包括PUCCH和PUSCH中的至少一项，所述下行数据可以包括PDCCH和PDSCH中的至少一项。基于此，所述TCI指示信息可以用于指示PUCCH、PUSCH、PDCCH和PDSCH中的至少一项与参考信号的准共址关系。
在实际应用中，可以在网络设备侧配置TCI池，TCI池中保存了参考信号对应的波束集合，当需要使用准共址关系时，可以从所述TCI池中选择合适的波束，根据所选择的波束可以确定其对应的参考信号，然后发送TCI指示信息，指示所述数据可以与所述参考信号准共址，从而使得终端设备可以根据TCI指示信息指示的准共址关系，确定使用哪个参考信号对应的波束来进行数据的接收或发送。
这样，通过TCI池加TCI指示信息的方式可以实现准共址关系的指示，无需在各个信道中配置TCI状态列表，当波束集合发生改变时，直接对TCI池进行修改即可，无需针对各个信道的配置分别进行修改。
本实施例提供的准共址关系指示方法，可以根据上行参考信号和/或下行参考信号的波束集合确定TCI池，并根据所述TCI池，发送TCI指示信息，所述TCI指示信息用于指示数据和参考信号的准共址关系，从而通过TCI池加TCI指示信息的方式快速准确地实现准共址关系的指示，无需在各个信道里分别配置TCI列表，有效减少了信息配置的冗余度和复杂程度，提高了系统效率。
在本申请实施例中，可以根据上行参考信号和/或下行参考信号的波束集合确定TCI池。可选地，所述上行参考信号的波束集合可以包括波束扫描时所有上行发射波束和/或上行接收波束；所述下行参考信号的波束集合可以包括波束扫描时所有下行发射波束和/或下行接收波束。
例如，所述上行参考信号的波束集合可以包括波束扫描时所有的上行发射波束，或者，可以包括波束扫描时所有的上行接收波束，或者，可以包括波束扫描时所有的上行发射波束以及所有的下行发射波束。所述下行参考信号的波束集合可以包括波束扫描时所有的下行发射波束，或者，可以包括波束扫描时所有的下行接收波束，或者，可以包括波束扫描时所有的下行发射波束以及所有的下行发射波束。从而将波束扫描时的所有发射和/或接收波束纳入考量范围，扩大准共址关系的范围。
可选地，根据上行参考信号和/或下行参考信号的波束集合确定TCI池，可以包括：根据所述上行参考信号和/或所述下行参考信号的波束集合中，发射波束和接收波束的所 有配对确定TCI池。波束的配对与参考信号具有对应关系，通过波束的配对确定TCI池后，能够通过TCI池快速准确地确定准共址关系中的参考信号，提高准共址关系的处理效率和准确率。
在实际应用中，可以根据上行参考信号的波束集合和下行参考信号的波束集合共同确定TCI池，也可以只根据上行参考信号的波束集合，或者，只根据下行参考信号的波束集合来确定TCI池。下面分别说明。
在第一种可选的实现方式中，可以根据上行参考信号的波束集合和下行参考信号的波束集合确定TCI池，所述上行参考信号的波束集合可以包括波束扫描时所有上行发射波束和所有上行接收波束，所述下行参考信号的波束集合可以包括波束扫描时所有下行发射波束和所有下行接收波束。
图6为本申请实施例提供的一种网络设备和终端设备的波束示意图。如图6所示，网络设备侧具有波束#1至#8，当然网络设备侧可根据具体情况形成宽度不同的波束；终端设备侧具有波束*1至*4，终端设备侧也可以根据具体情况形成宽度不同的波束。在波束扫描时，参考信号可以基于图中所示出的波束进行发射和接收。
上行参考信号可以使用终端设备侧的任一波束发射，使用网络设备侧的任一波束接收，下行参考信号可以使用网络设备侧的任一波束发射，使用终端设备侧的任一波束接收。
由于在基于波束的通信系统中，终端设备可以反馈各个下行波束的测量结果给网络设备，网络设备侧也会有各个上行波束的测量结果，所以网络设备侧有能力知道所有波束的配对信息。
可选地，在接入过程中，终端设备侧可以测量网络设备侧各个发射波束的质量，得到并反馈测量结果，网络设备侧可以测量各个终端设备侧发射波束的质量，得到对应的测量结果。
可选地，可以根据所述上行参考信号和所述下行参考信号的波束集合中，发射波束和接收波束的所有配对确定TCI池，提高准共址关系的适用性。
在根据所述上行参考信号和所述下行参考信号的波束集合中发射波束和接收波束的所有配对确定TCI池时，可以遍历所有的波束配对方式，得到对应的TCI池，例如表1。
表1本申请实施例提供的一种TCI池的示例
Figure PCTCN2021086259-appb-000001
如表1所示，网络设备侧可配置所有连接波束为一个TCI池。下行时，网络设备可以使用波束#1至#8作为发射波束，终端设备可以使用波束*1至*4作为接收波束；上行时，终端设备可以使用波束*1至*4作为发射波束，网络设备可以使用波束#1至#8作为接收波束。
不同的参考信号可以对应于不同的发射和接收波束。例如，在上行参考信号中，参考 信号1使用终端设备侧波束*1发射，网络设备侧波束#1接收；参考信号2使用终端设备侧波束*1发射，网络设备侧波束#2接收；以此类推，在波束扫描时，遍历所有的上行配对方式，可以有4×8＝32个上行参考信号，分别使用不同的网络设备侧波束和/或终端设备侧波束进行传输。
类似地，在下行参考信号中，参考信号33使用网络设备侧波束#1发射，终端设备侧波束*1接收；参考信号34使用网络设备侧波束#1发射，终端设备侧波束*2接收；以此类推，在波束扫描时，遍历所有的下行配对方式，可以有8×4＝32个下行参考信号，分别使用不同的网络设备侧波束和/或终端设备侧波束进行传输。
如表1所示，任一网络设备侧波束以及任一终端设备侧波束构成一个波束对，网络设备侧的8个波束和终端设备侧的4个波束，总共可以有2×8×4＝64个波束对。
可选地，在时分双工(Time Division Duplexing，TDD)模式下，所述波束对的数量等于网络设备侧波束的数量与终端设备侧波束的数量的乘积。
可选地，如果是TDD模式，上下行是对等的，上行的发射波束和下行的接收波束相同，上行的接收波束和下行的发射波束相同。
以图6为例，在下行时，网络设备的波束#1发射，终端设备的波束*2接收；那么在上行时，终端设备的波束*2发射，网络设备的波束#1接收，从而网络设备侧的8个波束和终端设备侧的4个波束，一共有32个波束配对。此时网络设备可形成一个与表1左半部分或右半部分类似的、有32个波束对的TCI池，上下行所有信道都可以从该TCI池中选取波束对。
可选地，在频分双工(Frequency Division Duplexing，FDD)模式下，所述波束对的数量等于网络设备侧波束的数量与终端设备侧波束的数量的乘积的预设倍，优选地，所述预设倍为2倍。
可选地，FDD模式下，上下行可以采用不同的波束对。例如，下行时，网络设备的波束#1发射，终端设备的波束*2接收；上行时，终端设备的波束*3发射，网络设备的波束#4接收，从而网络设备侧的8个波束和终端设备侧的4个波束，一共有64波束配对。此时网络设备可形成一个与表1类似的有64个波束对的TCI池，上下行所有信道都可以从该TCI池中选取波束对。
可选地，也可以在所有波束配对方式中选择一部分生成TCI池。例如，某些波束只用于发射不用于接收，或者，只用于接收不用于发射，那么可以相应的在表1中减少配对关系。
所述TCI池的具体表现形式也可以有多种。可选地，所述TCI池可以包括至少一个波束对的信息。所述波束对可以包括网络设备侧波束和终端设备侧波束。所述波束对的信息可以包括所述波束对中的网络设备侧波束的标识、终端设备侧波束的标识以及所述波束对对应的测量结果中的至少一种。
一个示例中，所述TCI池可以包括网络设备侧波束的标识、终端设备侧波束的标识以及波束对对应的测量结果，具体可参见表1，网络设备侧波束的标识和终端设备侧波束的标识分别以#和*开头，在此基础上，增加每个波束对对应的测量结果。
可选地，根据所述TCI池，发送TCI指示信息，可以包括：根据所述TCI池中至少一个波束对的信息，确定所述准共址关系中的上行参考信号和/或下行参考信号；根据所述准共址关系中的上行参考信号和/或下行参考信号，发送TCI指示信息。
可选地，可以从所述TCI池的至少一个波束对中，选择最合适的波束对用来传输数据，根据所选择的波束对，可以获知对应的参考信号，从而可以发送TCI指示信息，指示数据与对应的参考信号具有准共址关系。

可选地，在选择参考信号时，可以以波束对的测量结果作为考量因素，从而能够从TCI池中选出质量最好的波束对，提高数据传输的效率和准确率。
在另一示例中，所述TCI池可以包括网络设备侧波束的标识、终端设备侧波束的标识，而不必包括波束对对应的测量结果，各个波束对对应的测量结果可以保存在其它位置，在需要时可以从所述其它位置获取各个波束对对应的测量结果并使用，减少TCI池所需的信息长度。
可选地，对于任一波束对，可以从终端设备获取通过终端设备侧波束检测到的网络设备侧波束发射的信号的测量结果，和/或，对于任一波束对，可以通过网络设备侧波束检测终端设备侧波束发射的信号对应的测量结果。
可选地，终端设备可以通过自身的波束接收网络设备侧波束发射的信号，从而确定对应的波束对的测量结果，例如，终端设备侧波束*1接收网络设备侧波束#8发射的信号，对该信号进行测量得到的测量结果即为下行的波束#8与波束*1构成的波束对的测量结果。终端设备将各个下行的波束对的测量结果反馈给网络设备，网络设备可以据此来更新TCI池。
类似地，网络设备侧波束可以检测终端设备侧波束发射的信号对应的测量结果，例如网络设备侧波束#2接收终端设备侧波束*3发射的信号，对该信号进行测量得到的测量结果即为上行的波束*3与波束#2构成的波束对的测量结果。这样，通过网络设备侧波束和终端设备侧波束可以快速准确地检测出各个波束对对应的测量结果，从而为波束选择提供依据，提高波束选择的准确性。

在确定准共址关系中的参考信号时，可以仅确定上行参考信号，指示某一上行数据与所述上行参考信号具有准共址关系，例如，TCI池中，波束*2和波束#3构成的波束对的质量最好，该波束对与上行参考信号11对应，即参考信号11采用波束*2发射，波束#3接收，那么可以指示上行数据如PUCCH和/或PUSCH与上行参考信号11具有准共址关系，从而终端设备可以根据所述准共址关系知道需要通过波束*2发射上行数据。
或者，在确定准共址关系中的参考信号时，可以仅确定下行参考信号，指示某一下行数据与所述下行参考信号具有准共址关系，例如，TCI池中，波束#1和波束*4构成的波束对的质量最好，该波束对与下行参考信号36对应，即参考信号36采用波束#1发射，波束*4接收，那么可以指示下行数据如PDCCH和/或PDSCH与下行参考信号36具有准共址关系，从而终端设备可以根据所述准共址关系知道需要通过波束*4接收下行数据。
或者，在确定准共址关系中的参考信号时，可以既确定上行参考信号，又确定下行参考信号。例如，可以在TCI指示信息中，同时指示上行数据与上行参考信号11具有准共址关系，下行数据与下行参考信号36具有准共址关系，从而终端设备可以根据所述准共址关系知道需要通过波束*2发射上行数据，通过波束*4接收下行数据。
图7为本申请实施例提供的一种基于波束进行数据传输的原理示意图。如图7所示，当确定数据与某一参考信号具有准共址关系时，可以采用所述参考信号对应的波束对进行 数据传输。
例如，TCI指示信息指示PDSCH与某一下行参考信号具有准共址关系，该下行参考信号对应的波束对为：网络设备侧波束#4和终端设备侧波束*1，那么网络设备侧可以采用波束#4发射PDSCH，终端设备侧采用波束*1接收PDSCH。
在实际应用中，网络设备和终端设备可以先进行波束扫描，即遍历所有的波束配对方式进行参考信号的发射和接收，并保存波束扫描过程中得到的波束对的测量结果，当需要发送上行数据或下行数据时，可以从TCI池中选出测量结果最佳的波束对，通过TCI指示信息对准共址关系作出指示。

在第三种可选的实现方式中，可以根据下行参考信号的波束集合确定TCI池。可选地，所述下行参考信号的波束集合可以包括波束扫描时所有下行发射波束和/或下行接收波束。
相应的，根据下行参考信号的波束集合确定TCI池，可以包括：根据所述下行参考信号的波束集合中，发射波束和接收波束的所有配对确定TCI池。
在这种实现方式中，可以仅考虑下行参考信号的波束集合，TCI池的具体表现形式可以参考表1的左半部分。
根据所述TCI池，可以为下行数据选择合适的波束对，从而指示下行数据和下行参考信号的准共址关系。或者，在某些实现方式中，也可以指示上行数据与下行参考信号的准共址关系，即，通过下行参考信号对应的两个波束进行上行数据的发射和接收。例如，PUCCH与下行参考信号36准共址，下行参考信号36对应波束#1和波束*4，则PUCCH可以采用波束#1和波束*4进行发射和接收，只是发射波束和接收波束正好与下行参考信号36相反。
在上述第二种和第三种可选的实现方式中，给出了只根据上行参考信号的波束集合或只根据下行参考的波束集合确定TCI池的方案，其它未进行说明的地方均可以参照第一种可选的实现方式，此处不再赘述。

可选地，所述TCI指示信息可以包括以下至少一种：所述准共址关系中的上行参考信号的标识；所述准共址关系中的下行参考信号的标识；参考信号组合的标识；信道指示信息。

表2本申请实施例提供的一种TCI指示信息的示例
TCI-0 11 TCI-1 36
如表2所示，上行指示位可以为TCI-0，用于指示对应设置的标识11为上行参考信号的标识，即准共址关系中的参考信号包括上行参考信号11；类似地，下行指示位可以为TCI-1，用于指示对应设置的标识36为下行参考信号的标识，即准共址关系中的参考信号包括上行参考信号36。
可选地，所述TCI指示信息也可以仅指示上行的准共址关系或者仅指示下行的准共址关系，相应的，TCI指示信息中也可以仅设置上行指示位或下行指示位。通过TCI指示信息可以使终端准确获知指示的准共址关系是应用于上行还是应用于下行，进一步提高终端确定准共址关系的准确率。
终端设备可以维护有参考信号与波束的对应关系。终端设备接收到TCI指示信息后，根据TCI指示信息，可以确定准共址关系中的参考信号，进而可以确定参考信号对应的波束。

另一示例中，所述TCI指示信息可以包括参考信号组合的标识。可选地，所述参考信号组合包括所述准共址关系中的上行参考信号和下行参考信号。
在需要同时指示上行参考信号和下行参考信号的情况下，可以通过一个参考信号组合的标识来表示准共址关系中的上行参考信号和下行参考信号。
例如，可选的上行参考信号有n个，可选的下行参考信号有m个，那么共有n×m种组合，其中包含了任意一个上行参考信号和任意一个下行参考信号的组合。
可选地，在TCI指示信息需要包括参考信号组合的标识时，网络设备可以先根据波束测量结果选择合适的波束并确定对应的上行参考信号和下行参考信号，再根据所述上行参考信号和下行参考信号，确定对应的参考信号组合，根据所述对应的参考信号组合，确定所述参考信号组合的标识。

这样，终端设备可以根据所述信道指示信息，确定哪些信道需要使用TCI指示信息中指示的准共址关系，提高TCI指示的精准度。
可选地，各个信道与参考信号的准共址关系可以是有时间限制的，在确定参考信号后，可以在一段时间内使信道与该参考信号准共址，从而提高准共址关系的实时性。

当准共址关系改变时，直接在DCI中改变即可。当DCI中携带信道指示信息，且信道指示信息与高层信令配置的信息有冲突时，可以以DCI中携带的信道指示信息为准，从而能够在准共址变化时快速通知终端设备，提高信息传输效率。
在上述各实施例提供的技术方案的基础上，可选地，所述TCI指示信息指示的准共址关系包括至少一个上行参考信号和至少一个下行参考信号。
可选地，在准共址关系中包括多个上行参考信号时，终端设备可以通过多个波束发射信号，和/或，网络设备可以通过多个波束接收信号；在准共址关系中包括多个下行参考信号时，网络设备可以通过多个波束发射信号，和/或，终端设备可以通过多个波束接收信号。这样，可以通过多个波束发射或接收信号，提高信号传输的准确率。
