波束指示方法、装置、终端及网络侧设备

本申请主张在2020年7月27日在中国提交的中国专利申请号No.202010731568.6的优先权,其全部内容通过引用包含于此。
技术领域
本申请涉及通信技术领域,尤其涉及一种波束指示方法、装置、终端及网络侧设备。
背景技术
在新空口(New Radio,NR)系统中,下行信道包括物理下行共享信道(Physical Downlink Shared Channel,PDSCH),物理下行控制信道(Physical Downlink Control Channel,PDCCH),上行信道包括物理上行共享信道(Physical Uplink Shared Channel,PUSCH),以及物理上行控制信道(Physical Uplink Control Channel,PUCCH)。
对于高频传输(NR中的FR2频段),由于传输范围受限,通常上下行信道会经过波束赋形后进行传输以增强覆盖。赋形波束的方向可以通过上下行参考信号的波束扫描确定,例如使用不同方向的信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)或者探测参考信号(Sounding Reference Signal,SRS)进行波束扫描,选择波束质量最好的参考信号所在方向用于上行或者下行传输。
在确定了不同信道的波束方向后,需要使用信令指示信道传输时的波束,即波束指示。对于PUCCH信道,基站通过高层信令SpatialRelationInfo半静态的配置给终端多个波束方向,并通过媒体接入控制层控制单元(Medium Access Control-Control Element,MAC-CE)指示激活其中的一个。对于PUSCH,基站选择的上行波束是由动态信令下行控制信息(Downlink Control Information,DCI)中SRS资源指示(SRS Resource Indicator,SRI)域所指的SRS资源的SpatialRelationInfo间接指示的。对于PDCCH信道,基站通过高 层信令为每个控制资源集(Control Resource Set,CORESET)配置多个传输配置指示状态(Transmission Configuration Indicator state,TCI state),并通过MAC-CE指示激活其中的一个。对于PDSCH信道,基站通过DCI信令中的TCI域指示一个TCI state,表示信道的波束方向。
在相关技术的方案中,不同的信道使用不同的波束指示信令,且各个信道独立进行波束指示。这样不同的信道可能使用各自不同的波束传输。而实际应用中的一个重要场景是多个信道使用相同的波束方向,或者多个信道所使用的波束方向具有某些关联性。例如,用于资源调度的PDCCH和传输用户数据的PDSCH使用相同的波束方向传输;上行控制信道PUCCH和上行数据信道PUSCH也会使用相同的波束方向。另外,当波束互易性存在时,上行信道和下行信道也可能使用同一个波束方向。此时,当前这种独立波束指示的方式,在指示波束时缺乏足够的灵活性。

本申请实施例提供了一种波束指示方法,如图2所示,该方法在应用于终端侧时,包括:
步骤21,所述终端接收用于指示传输第一对象的第一波束方向的指示消息,所述第一波束方向与所述终端传输第二对象所使用的第二波束方向相同或不同,所述第一对象和第二对象为信道和参考信号中的一种,所述第一波束方向为预先配置的TCI状态集合中的一个TCI状态所指示的方向。
这里,本申请实施例在向终端发送的指示消息中指示第一对象的第一波束方向,且该第一对象的波束方向(为了便于描述,称之为第一波束方向),与第二对象的波束方向(为了便于描述,称之为第二波束方向)可以是相同或者不同的。所述第一对象可以是信道和参考信号中的一种,类似的,所述第二对象也可以是信道和参考信号中的一种。所述第一对象与所述第二对象分别为不同的信道/参考信号。所述信道可以包括PDSCH、PDCCH、PUSCH和PUCCH中的一种或多种,所述参考信号可以包括CSI-RS和SRS中的一种或多种。
另外,所述指示消息指示波束的具体方式,可以是:通过TCI状态、准共址(Quasi co-location,QCL)参数、空间关系信息(SpatialRelationInfo)、上行参考信号的索引、下行参考信号的索引、同步信号的索引、上行信道和下行信道中的一种或多种进行指示。其中,在采用所述上行参考信号的索引、下行参考信号的索引、同步信号的索引、上行信道或下行信道指示波束方向时,所指示的波束方向为:所述上行参考信号、下行参考信号、同步信号、上行信道或下行信道最近一次使用的波束方向。
步骤22,所述终端根据所述第一波束方向,进行所述第一对象的传输。
这里,本申请实施例在步骤22中利用所述指示消息指示的第一波束方向,进行所述第一对象的传输。
需要说明的是,本申请实施例所述的传输包括发送和/或接收。例如,当所述第一波束方向为发送波束的方向时,在发送所述第一对象时,可以使用所述发送波束的方向进行发送;在接收所述第一对象时,可以在所述发送波束的方向上接收所述第一对象。类似的,当所述第一波束方向为接收波束的方向时,在发送所述第一对象时,可以在所述接收波束的方向上进行发送;在接收所述第一对象时,可以使用所述接收波束的方向进行接收。
通过以上步骤,本申请实施例可以利用一个指示消息,指示第一对象的第一波束方向,且该第一波束方向可以与第二对象的第二波束方向相同或不同,从而可以在进行波束方向的指示时,指示具有关联关系的波束方向,实现了灵活的波束指示。另外,本申请实施例还可以在需要改变波束时,发送上述指示消息,从而可以实现动态的波束指示,增加了上下行波束控制的灵活性。
下面提供上述步骤21的多种实现方式。
1)作为一种实现方式,在上述步骤21中,所述终端接收携带有第一TCI状态的第一指示消息,其中,所述第一指示消息中的第一TCI状态用于指示所述第一波束方向,所述第一TCI状态为第一TCI状态集合中的一种TCI状态,所述第一TCI状态集合是预先为所述终端配置的TCI状态集合。
在该实现方式中,第一对象和第二对象可以是信道和参考信号中的任一种,所述信道包括PDCCH、PUCCH、PDSCH和PUSCH,所述参考信号包括SRS和CSI-RS。
在上述步骤21之前,终端接收网络发送的携带有第二TCI状态的第二指示消息,其中,第二指示消息用于指示传输第二对象的第二波束方向;然后,根据所述第二TCI状态指示的第二波束方向,进行所述第二对象的传输,其中,所述第二TCI状态也是所述第一TCI状态集合中的一种TCI状态,且,所述第一TCI状态与所述第二TCI状态相同或不同。
这样,网络可以为终端配置同一个TCI状态集合(如上文的第一TCI状态集合),然后针对不同的对象分别利用该集合中的一个TCI状态来指示其波 束方向,不同的对象的波束方向可以相同或不同。在两个对象的波束方向不同时,可以使用不同的TCI状态来指示对应的波束方向;在在两个对象的波束方向相同时,可以使用同一个TCI状态来指示对应的波束方向。
在上述实现方式中,网络预先为终端配置了第一TCI状态集合,该集合包括多个TCI状态。这样,后续网络可以通过发送携带有TCI状态的指示消息,来为终端指示具体的波束方向。
作为第一TCI状态集合的一种配置方式,网络可以向终端发送配置消息;终端接收上述配置消息,根据上述配置消息,配置包括有多个TCI状态的所述第一TCI状态集合。所述配置消息具体可以是RRC信令消息,其携带有多个TCI状态。
作为第一TCI状态集合的另一种配置方式,网络可以先配置一个包含更多TCI状态的第二TCI状态集合,然后根据需要再从上述第二TCI状态集合中选择出部分或全部TCI状态,配置为所述第一TCI状态集合。此时,所述终端接收第一配置消息,根据所述第一配置消息,配置第二TCI状态集合,所述第一配置消息携带有第一数量的TCI状态;然后,所述终端接收第二配置消息,根据所述第二配置消息,配置所述终端的所述第一TCI状态集合,其中,所述第一TCI状态集合包含有所述第二TCI状态集合中的全部或部分TCI状态。所述第一配置消息可以是RRC信令消息,所述第二配置消息可以是MAC-CE。
2)作为另一种实现方式,在上述步骤21中,所述终端接收携带有第一TCI状态的第三指示消息,其中,所述第三指示消息中的第一TCI状态用于同时指示所述第一波束方向和第二波束方向,所述第一TCI状态为第三TCI状态集合中的一种TCI状态,所述第三TCI状态集合为所述第一对象和第二对象配置的同一个TCI状态集合。此时,所述第一波束方向与第二波束方向相同。
该实现方式中,所述第一对象为PUCCH和PDCCH中的一个,所述第二对象为PUCCH和PDCCH中的另一个。
在该实现方式中,网络为第一对象和第二对象配置了同一个TCI状态集 合,即上述的第三TCI状态集合,并利用一个指示消息(第三指示消息)中携带的一个TCI状态来指示不同对象的同一个波束方向。该实现方式特别适用于上下行的对象之间,例如,所述第一对象为PUCCH,所述第二对象为PDCCH。
在上述步骤21之前,网络可以通过配置消息,分别为第一、第二对象配置同一个TCI状态集合。例如,所述终端接收第三配置消息,根据所述第三配置消息中携带的TCI状态,为第二对象配置第三TCI状态集合;以及,所述终端接收第四配置消息,根据所述第四配置消息,为所述第一对象配置相同的第三TCI状态集合,从而为第一、第二对象均配置了第三TCI状态集合。当然,也可以通过一个配置消息进行配置,例如,所述终端接收第五配置消息,根据所述第五配置消息,为所述第一对象和第二对象配置所述第三TCI状态集合。
3)作为又一种实现方式,在上述步骤21中,所述终端接收携带有第一TCI状态的第四指示消息,其中,所述第四指示消息中的第一TCI状态用于指示所述第一波束方向,所述第一TCI状态为所述第一对象所配置的第四TCI状态集合中的一种TCI状态,且,所述第一TCI状态指示的第一波束方向与第二TCI状态指示的所述第二波束方向相同或不同,所述第二TCI状态为所述第二对象所配置的第五TCI状态集合中的一种TCI状态。
该实现方式中,所述第一对象为SRS,所述第二对象为PUCCH。
在该实现方式中,网络为第一对象和第二对象分别配置对应的TCI状态集合,即上述的第四TCI状态集合和第五TCI状态集合,其中,这两个集合中的TCI状态可以全部相同、部分相同或完全不同。
另外,所述终端还可以接收网络发送的携带有第二TCI状态的第五指示消息,其中,所述第五指示消息中的第二TCI状态用于指示传输第二对象的所述第二波束方向,所述第二TCI状态为所述第二对象所配置的第五TCI状态集合中的一种TCI状态;所述终端根据所述第二TCI状态指示的第二波束方向,进行所述第二对象的传输,其中,所述第二波束方向与第一波束方向相同或不同。在所述第二波束方向与第一波束方向相同时,所述第四、第五TCI状态集合中包括有相同的TCI状态,以指示相同的波束方向。
类似的,在接收所述第四指示消息之前,所述终端可以接收网络发送的配置消息,配置所述第四TCI状态集合。在接收所述第五指示消息之前,所述终端可以接收网络发送的配置消息,配置所述第五TCI状态集合。当然,网络也可以通过同一个配置消息来配置上述第四、第五TCI状态集合。
以上实现方式1~3中,上述步骤21中的指示消息具体可以是媒体接入控制层控制单元(MAC-CE)信令,所述MAC-CE信令携带有激活相应TCI状态(如第一TCI状态)的指示信息。或者,上述步骤21中的指示消息具体可以是调度所述第一对象传输或激活所述第一对象的下行控制信息(DCI)信令,其中,DCI信令携带有第一TCI状态的指示信息。
4)作为又一种实现方式,在上述步骤21中,所述终端接收第六指示消息,所述第六指示消息携带有将所述第二波束方向作为所述第一波束方向的指示信息。通过第六指示消息,直接将第二对象的波束方向配置为第一对象的波束方向。所述第二波束方向为预先为所述第二对象配置的TCI状态集合中的一个TCI状态所指示的方向,由于第一波束方向与第二波束方向相同,因此所述第一波束方向也是预先配置的TCI状态集合中的一个TCI状态所指示的方向。
例如,所述第二对象为PDCCH,所述第一对象为PDSCH、CSI-RS、PUCCH、PUSCH和SRS中的至少一个。另外,所述第二波束方向可以是最近一次传输所述第二对象所使用的波束方向。
此时,所述第六指示消息具体可以是调度所述第一对象传输的DCI信令或者激活所述第一对象的MAC-CE信令。更具体的:
在所述第一对象为PDSCH时,所述第六指示消息为DCI信令;
在所述第一对象为CSI-RS时,所述第六指示消息为DCI信令或MAC-CE信令;
在所述第一对象为PUCCH时,所述第六指示消息为MAC-CE信令;
在所述第一对象为PUSCH时,所述第六指示消息为DCI信令;
在所述第一对象为SRS时,所述第六指示消息为DCI信令或MAC-CE信令。
通过以上提供的多种实现方式,本申请实施例可以实现灵活的波束方向 指示,支持不同的信道/参考信号使用相同或不同的波束。另外,本申请实施例可以通过MAC-CE或者动态信令的方式进行波束方向的指示,可以降低波束指示的时延和信令开销。
以上从终端侧介绍了本申请的波束指示方法的至少一种实现方式,下面请参照图3,本申请实施例提供的波束指示方法,在应用于网络侧设备,如基站时,包括:

另外,在发送所述第一指示消息之前,网络侧设备还可以发送携带有第二TCI状态的第二指示消息,其中,第二指示消息用于指示传输第二对象的第二波束方向,其中,所述第二TCI状态为所述第一TCI状态集合中的一种TCI状态,且,所述第一TCI状态与所述第二TCI状态相同或不同。
另外,在发送所述第二指示消息之前,网络侧设备还可以发送第一配置消息,所述第一配置消息用于为终端配置第二TCI状态集合,所述第一配置消息携带有第一数量的TCI状态;以及,发送第二配置消息,为终端配置所述第一TCI状态集合,所述第二配置消息携带有第二数量的TCI状态,其中,所述第二数量小于或等于所述第一数量。通过上述配置消息,可以为终端配置所述第一TCI状态集合。具体的,所述第一TCI状态集合包含有所述第二TCI状态集合中的全部或部分TCI状态。
这里,对应于前文的实现方式2,在上述步骤31中,网络侧设备可以生成携带有第一TCI状态的第三指示消息,其中,所述第三指示消息中的第一 TCI状态用于同时指示所述第一波束方向和第二波束方向,所述第一TCI状态为第三TCI状态集合中的一种TCI状态,所述第三TCI状态集合为所述第一对象和第二对象配置的同一个TCI状态集合。

这里,对应于前文的实现方式3,在上述步骤31中,网络侧设备可以生成携带有第一TCI状态的第四指示消息,其中,所述第四指示消息中的第一TCI状态用于指示所述第一波束方向,所述第一TCI状态为所述第一对象所配置的第四TCI状态集合中的一种TCI状态,且,所述第一TCI状态指示的第一波束方向与第二TCI状态指示的所述第二波束方向相同或不同,所述第二TCI状态为所述第二对象所配置的第五TCI状态集合中的一种TCI状态。
另外,网络侧设备还可以向所述终端发送携带有第二TCI状态的第五指示消息,其中,所述第五指示消息中的第二TCI状态用于指示传输第二对象的所述第二波束方向。
类似的,上述第一至第五指示消息,具体可以是MAC-CE信令,其中,所述MAC-CE信令携带有激活第一TCI状态的指示信息;或者,上述第一至第五指示消息,具体可以是DCI信令,其中,所述DCI信令携带有第一TCI状态的指示信息。
这里,对应于前文的实现方式4,在上述步骤31中,网络侧设备可以生成携带有将所述第二波束方向作为所述第一波束方向的指示信息。
具体的,所述第二对象为PDCCH,所述第一对象为PDSCH、CSI-RS、PUCCH、PUSCH和SRS中的至少一个。所述第二波束方向为最近一次传输所述第二对象所使用的波束方向。所述指示消息为调度所述第一对象传输的DCI信令或者激活所述第一对象的MAC-CE信令。

在所述第一对象为SRS时,所述指示消息为DCI信令或MAC-CE信令。
以下对本申请实施例的波束指示方法在终端和网络侧的实现均进行了说明。下面进一步提供应用本申请实施例波束指示方法的若干示例。以下举例多以第一波束方向和第二波束方向相同为例进行说明。
示例1:
基站通过RRC信令为终端配置第二TCI状态集合,其中包括M=128个TCI状态,表示为:C1={TCI_0,TCI_1,…,TCI_127}。基站通过第一MAC-CE信令指示终端,第一TCI状态集合为C2={tci_0,tci_1,…,tci_63}。其中,tci_i∈C1,i=0,1,…,63。这里,第一TCI状态集合包括N=64个TCI状态,且每个状态均从第二TCI状态集合中选择。本文中,tci_i和TCI_i各自表示的TCI状态可以是相同或不同的。
当基站传输PDCCH信道时,其通过第二MAC-CE信令从C2中激活一个TCI状态并告知终端,如激活tci_5。这样PDCCH信道将使用tci_5对应的波束方向进行传输,终端(UE)使用相应的接收波束进行接收;当终端发送PUCCH信道时,基站通过第三MAC-CE信令从C2中激活相同的TCI状态,即激活tci_5。这样终端将使用tci_5对应的接收波束方向作为发送波束方向进行PUCCH信道的传输。当终端传输PUSCH信道时,基站使用第一DCI信令调度PUSCH信道传输。在所述第一DCI信令中,包含一个TCI指示域,其指所调度的PUSCH信道所使用的波束方向。这里TCI指示域可以指示tci_5。这样PUSCH也使用tci_5对应的接收波束方向作为发送波束方向进行传输。从而通过不同信道分别配置从第一TCI状态集合中选择的同一个TCI状态,实现了多个信道使用相同的发送波束。
示例2:
基站通过RRC信令为PDCCH信道配置了第三TCI状态集合,表示为 C3={tci_0,tci_1,…,tci_63}。即包含64个TCI状态。同时基站通过RRC信令为PUCCH信道配置了相同的TCI状态集合,即{tci_0,tci_1,…,tci_63}。基站侧通过MAC-CE信令激活C3中的tci_6作为PDCCH的传输波束。而系统中预定义此MAC-CE信令同时用于激活PUCCH的传输波束,这样PUCCH的传输也使用tci_6对应的波束方向。
示例3:
基站通过RRC信令为每个SRS资源配置8个TCI状态,表示为{tci_0,tci_1,…,tci_7}。同时基站为PUCCH信道配置8个TCI状态,表示为{TCI_0,TCI_1,…,TCI_7}。基站通过第一MAC-CE信令激活PUCCH信道的TCI_6,指示终端使用TCI_6对应的波束发送PUCCH信道。进一步,基站通过第二MAC-CE信令激活SRS资源的tci_1,指示终端使用tci_1对应的波束发送SRS。或者,基站通过DCI信令触发SRS资源的发送,所述DCI信令中包含TCI指示域,指示从基站配置的8个TCI状态中选择一个,作为此SRS资源的发送波束。例如,DCI信令指示tci_1,则终端使用tci_1对应的波束发送SRS。若RRC信令配置的tci_1与TCI_6对应相同的波束方向,则可以支持SRS资源与PUCCH信道使用相同的发送波束。
示例4:
系统预定义默认波束指示信令,所述信令指示终端忽略RRC配置的波束相关信息,而采用默认波束进行信道或参考信号的传输。所述的默认波束为最近一次的PDCCH传输的波束。
对于PDSCH信道,可以通过DCI信令指示是否采用默认波束。一种方式是在调度DCI信令中增加一个默认波束指示域。若此指示域为ON状态,则说明本次传输采用默认波束。
对于CSI-RS参考信号,可以通过MAC-CE信令或DCI信令指示是否采用默认波束。例如,对于非周期CSI-RS,在其触发的DCI信令中,增加一个默认波束指示域进行指示;对于半持续CSI-RS通过激活此CSI-RS的MAC-CE信令指示是否采用默认波束;而对于周期CSI-RS也可以采用新增MAC-CE信令指示是否采用默认波束。
对于PUCCH信道,所述默认波束指示信令可以由MAC-CE指示。当不 采用默认波束时,所述MAC-CE信令可以激活一个TCI状态;否则此信令指示采用默认波束。
对于PUSCH信道,所述默认波束可以通过DCI进行指示。一种方式可以在调度此PUSCH信道的DCI中,增加默认波束指示域。
对于SRS参考信号,可以通过MAC-CE或DCI信令进行指示。其具体方式与CSI-RS类似,这里不再赘述。
通过以上各个信道的配置,所有信道和参考信号均可以采用与PDCCH相同的波束进行传输。
以上介绍了本申请实施例的各种方法。下面将进一步提供实施上述方法的装置。
