在现有技术中,采用RRC配置用于定位的SRS的路径损耗参考信号,具体如下:
Figure PCTCN2020102706-appb-000001
当需要更新用于定位的SRS的路径损耗参考信号时,网络侧通过RRC重配置消息来通知UE,这种方式增加了RRC信令开销,并且延时也比较大。目前引入了基于媒体接入控制(MAC,Medium Access Control)控制单元(CE,Control Element)更新普通SRS的路径损耗参考信号的方式,其中,前述普通SRS可以指不同于用于定位的SRS的其他SRS。该MAC CE为SRS路径损耗参考信号更新MAC CE(SRS Pathloss Reference RS Update MAC CE)。由于普通SRS的路径损耗参考信号与用于定位的SRS 的路径损耗参考信号不同,因此,现有的SRS Pathloss Reference RS Update MAC CE无法直接应用于更新用于定位的SRS的路径损耗参考信号。本申请实施例提出一种新的MAC CE,用于配置用于定位的SRS的路径损耗参考信号。或者,本申请实施例扩展现有的SRS Pathloss Reference RS Update MAC CE、或者扩展现有的其他用途的MAC CE,用于配置用于定位的SRS的路径损耗参考信号。其中,前述配置可以指网络设备为终端设备初次配置路径损耗参考信号,也可以指在初次配置之后、网络设备为终端设备更新路径损耗参考信号。在以下实施例中,将结合附图对前述几种方式做详细说明。
本申请实施例提出一种路径损失参考信息的配置方法,图2是根据本申请实施例的一种路径损失参考信息的配置方法200的实现流程图,该方法可选地可以应用于图1所示的***,例如应用于图1所示***中的终端设备,但并不仅限于此。该方法包括以下内容的至少部分内容。
S210:接收第一媒体接入控制(MAC)控制单元(CE)。
其中,第一MAC CE用于为终端设备配置用于定位的SRS的路径损耗参考信号。
可选地,该第一MAC CE用于为终端设备更新用于定位的SRS的路径损耗参考信号;或者,该第一MAC CE也可以用于为终端设备初次配置用于定位的SRS的路径损耗参考信号。
根据接收到的第一MAC CE,UE能够获取网络侧为其配置的用于定位的SRS的路径损耗参考信号。
可选地,上述第一MAC CE用于为终端设备配置用于定位的SRS的SRS资源集(SRS resource set)使用的路径损耗参考信号;或者,上述第一MAC CE用于为终端设备配置用于定位的SRS的SRS资源(SRS resource)使用的路径损耗参考信号。从而用于指示该SRS resource set要使用的路径损耗参考信号(pathloss reference RS)、或者指示该SRS resource要使用的pathloss reference RS。
在一些实施方式中,上述第一MAC CE指示的路径损耗参考信号包括以下至少一项:
服务小区同步信号块(SSB);
邻小区SSB;
下行(DL,Downlink)定位参考信号(PRS,Positioning Reference Signal);
信道状态信息(CSI,Channel State Information)-参考信号(RS,Reference Signal);
相应的,上述第一MAC CE指示以下至少一项:
服务小区SSB的标识;
邻小区SSB的标识和邻小区SSB对应的小区信息;
DL PRS的标识;
CSI-RS的标识。
其中,服务小区SSB、邻小区SSB、DL PRS为现有的用于定位的SRS的路径损耗参考信号的类型,本申请实施例可以扩展出一种新的用于定位的SRS的路径损耗参考信号的类型,即CSI-RS。
第一MAC CE配置的路径损耗参考信号为上述不同类型时,该第一MAC CE相应地指示上述不同类型的路径损耗参考信号的标识信息;可选地,该第一MAC CE还可以包括路径损耗参考信号的其他相关信息。
例如,在第一MAC CE配置的路径损耗参考信号包括服务小区SSB的情况下,该第一MAC CE指示服务小区SSB的标识,如服务小区SSB的索引。其中,所述的指示可以指第一MAC CE中包括服务小区SSB的标识,也可以指第一MAC CE中包括其他能够间接指示服务小区SSB的标识的信息。在以下示例中,“指示”一词的含义与本处相同。进一步地,该第一MAC CE中还可以指示服务小区SSB对应的小区信息,如物理小区标识(PCI,Physical Cell ID)。
又如,在第一MAC CE配置的路径损耗参考信号包括邻小区SSB的情况下,该第一MAC CE指示邻小区SSB的标识和邻小区SSB对应的小区信息。其中,邻小区SSB的标识具体可以为服务小区SSB的索引,邻小区SSB对应的小区信息具体可以为PCI。
又如,在第一MAC CE配置的路径损耗参考信号包括DL PRS的情况下,该第一MAC CE指示DL PRS的标识,如DL PRS的索引。进一步地,该第一MAC CE还可以指示DL PRS所属的配置信息。可选地,DL PRS所属的配置信息包括DL PRS的资源集标识和/或DL PRS的资源标识,如包括DL PRS的资源集的索引和/或DL PRS的资源的索引。
又如,在第一MAC CE配置的路径损耗参考信号包括CSI-RS的情况下,该第一MAC CE指示CSI-RS的标识。
为了能够配置上述不同类型的路径损耗参考信号,可选地,本申请实施例将第一MAC CE中的路径损耗参考信号的标识的长度设置为8比特(bit)。
由于第一MAC CE能够指示不同类型的路径损耗参考信号,在一些实施方式中,第一MAC CE中可以包含第一指示信息,用于指示本次更新的路径损耗参考信号的类型。
例如,如果路径损耗参考信号的类型有三种,包括服务小区SSB、邻小区SSB、DL PRS;那么,该第一指示信息长度可以为1比特(bit),该1bit的第一指示信息的两个不同取值分别指示路径损耗参考信号的类型为SSB或DL PRS。进一步地,该第一指示信息长度可以为2bit,在指示路径损耗参考信号的类型为SSB的情况下,进一步区分服务小区SSB和邻小区SSB。
此外,第一MAC CE还可以指示该更新的路径损耗参考信号是应用于哪个服务小区的哪个带宽部分(BWP,BandWidth Part)、以及指示更新哪个SRS资源集的路径损耗参考信号;相应地,该第一MAC CE可以指示以下至少一项,以对上述信息进行指示:
服务小区的标识;
UL BWP的标识;
SRS资源集的标识。
在一些实施方式中,上述第一MAC CE可以是为用于定位的SRS新定义的MAC CE,或者扩展已有的SRS Pathloss Reference RS Update MAC CE。或者,本申请实施例还可以扩展已有的一种MAC CE,该MAC CE用于激活或者去激活用于定位的SRS、并指示SRS资源对应的空间关系,如SP Positioning SRS Activation/Deactivation MAC CE);该MAC CE可以称为第二MAC CE。前述两种扩展现有MAC CE的实施方式中,扩展后生成的第一MAC CE中除指示路径损耗参考信号的相关信息之外,还指示扩展之前该MAC CE中原有的信息,具体将在后续实施例2和实施例3中详细介绍。
实施例1:
图3是本申请实施例1的第一MAC CE的结构示意图。该第一MAC CE是为用于定位的SRS引入的新的MAC CE,用于配置用于定位的SRS的路径损耗参考信号。
可选地,该第一MAC CE指示SRS资源集要使用的路径损耗参考信号;和/或,SRS资源要使用的路径损耗参考信号。
如图3所示,该第一MAC CE包括以下字段(field):

BWP标识(BWP ID)字段:该字段指示上行(UL)带宽部分(BWP)作为TS38.212[9]中规定的DCI带宽部分指示符字段(DCI bandwidth part indicator field)的代码点。其中,包含已激活的SRS资源集。该字段的长度可以设置为2bit。
SRS资源集标识(SRS Resource Set ID)字段:该字段指示SRS资源集的标识,该标识可以为由TS 38.331[5]中规定的SRS-PosResourceSetId。该字段的长度可以设置为4bit。
路径损耗参考信号标识(Pathloss Reference RS ID)字段:该字段指示路径损耗参考信号的标识,该标识可以为由TS 38.331[5]中规定的srs-PathlossReferenceRS-pos-Id。该字段的长度可以设置为8bit。
在本实施例中,第一MAC CE指示的路径损耗参考信号可以包括以下几种:
服务小区SSB;
邻小区SSB;
DL PRS;
CSI-RS。
对应地,上述Pathloss Reference RS ID字段可以具体指示服务小区SSB的标识、邻小区SSB的标识、DL PRS的标识、CSI-RS的标识。
在第一MAC CE指示的路径损耗参考信号为服务小区SSB时,可选地,该第一MAC CE还可以指 示该服务小区对应的小区信息,如PCI。
在第一MAC CE指示的路径损耗参考信号为邻小区SSB时,该第一MAC CE还指示该邻小区对应的小区信息,如PCI。
如图3所示,为指示上述PCI,第一MAC CE中可以包含PCI字段,用于指示服务小区SSB或邻小区SSB对应的小区信息;可选地,该字段包含物理小区标识,该物理小区标识可以为TS 38.331[5]和/或TS 37.355[23]中规定的PhysCellId。该字段的长度可以设置为10bit。可选地,当第一MAC CE指示的路径损耗参考信号为服务小区SSB时,第一MAC CE中可以包含或不包含PCI字段;如果不包含PCI字段,则第一MAC CE不包含图3中所示的第6个字节(Oct6)和第7个字节(Oct7)。当第一MAC CE指示的路径损耗参考信号为邻小区SSB时,第一MAC CE中包含PCI字段,用于指示邻小区对应的PCI。
在第一MAC CE指示的路径损耗参考信号为DL PRS时,该第一MAC CE还可以指示该DL PRS所属的配置信息,如DL PRS的资源集标识(DL-PRS Resource Set ID)和/或DL PRS的资源标识(DL-PRS Resource ID)。
如图3所示,第一MAC CE中可以包含DL PRS的资源集标识(DL-PRS Resource Set ID)字段,用于指示DL PRS的资源集标识;可选地,该字段包含DL-PRS资源集的索引,该索引可以为37.355[23]中规定的nr-DL-PRS-ResourceSetId。第一MAC CE中还可以包含DL PRS的资源标识(DL-PRS Resource ID)字段,用于指示DL PRS的资源集标识;可选地,该字段包含DL-PRS资源的索引,该索引可以为37.355[23]中规定的nr-DL-PRS-Resource-Id。
进一步地,如图3所示,第一MAC CE中可以包含指示信息(F)字段,该指示信息可以为上述第一指示信息,用于指示路径损耗参考信号的类型。图3中所示的F字段长度为1bit,该1bit的2个不同取值可以分别用于指示路径损耗参考信号是SSB或DL PRS。如果该F字段的长度为2bit,则可以进一步区分SSB是服务小区SSB还是邻小区SSB。例如,F字段长度为2bit时,取值“00”或“01”表示路径损耗参考信号的类型为DL PRS,取值“10”表示路径损耗参考信号的类型为服务小区SSB,取值“11”表示路径损耗参考信号的类型为邻小区SSB。当然,前述F字段的取值及指示内容仅为一种举例,本申请实施例对F字段的指示方式不做限制。图3中的R字段为保留字段,本申请实施例可以采用任意的N个(N为正整数)保留字段作为F字段,用于指示指示路径损耗参考信号的类型。
在一些实施方式中,如图3所示,服务小区标识(Serving Cell ID)字段和BWP标识字段可以设置于第一MAC CE中的第一个字节;第一指示信息(F)字段和SRS资源集标识(SRS Resource Set ID)字段可以设置于第一MAC CE中的第二个字节;路径损耗参考信号标识(Pathloss Reference RS ID)字段可以设置于第一MAC CE中的第三个字节。第一MAC CE中的后续字段可以为可选字段。

相应地,本实施例可以扩展DL PRS的资源集标识(DL-PRS Resource Set ID)字段、DL PRS的资源标识(DL-PRS Resource ID)字段及PCI字段,各字段的内容可以与实施例1中相应字段的内容相同,在此不再赘述。
可选地,本实施例可以将该MAC CE中的任意N个(N为正整数)保留(R)字段作为第一指示信息(F)字段,用于指示路径损耗参考信号的类型。可选地,该指示信息为上述第一指示信息。该指示信息字段的具体指示方式可以与实施例1的内容相同,在此不再赘述。
在本实施例中,服务小区标识(Serving Cell ID)字段和BWP标识字段可以设置于第一MAC CE中的第一个字节;第一指示信息(F)字段和SRS资源集标识(SRS Resource Set ID)字段可以设置于第一MAC CE中的第二个字节;路径损耗参考信号标识(Pathloss Reference RS ID)字段可以设置于第一MAC CE中的第三个字节。第一MAC CE中的后续字段可以为可选字段。
实施例3:
本实施例扩展现有的SP Positioning SRS Activation/Deactivation MAC CE,使得该MAC CE在具备激活/去激活用于定位的SRS及指示SRS资源对应的空间关系功能的同时,还可以更新用于定位的SRS的路径损耗参考信号。
可选地,该第一MAC CE指示SRS资源集要使用的路径损耗参考信号;和/或,SRS资源要使用的路径损耗参考信号。
图5是本申请实施例3的第一MAC CE的结构示意图。可选地,如图5所示,路径损耗参考信号信息(Pathloss reference RS info)是本实施例扩展的部分,可以用于指示路径损耗参考信号。Pathloss reference RS info之前的部分为现有的SP Positioning SRS Activation/Deactivation MAC CE中包含的内容,用于激活/去激活用于定位的SRS、以及指示SRS资源对应的空间关系。具体包括:
激活/去激活(A/D)字段:该字段用于指示激活或去激活被指示的SP Positioning SRS资源集。该字段长度为1bit,取值为1时表示激活,取值为0是表示去激活。
Positioning SRS的资源集的小区标识(Positioning SRS Resource Set’Cell ID)字段:该字段用于指示服务小区,其包含激活/去激活的Positioning SRS资源集。如果C字段被设置为0,该字段也用于指示包含被Spatial Relation for Resource IDi字段指示的所有资源的服务小区的标识。该字段长度为5bit。
Positioning SRS的资源集的BWP标识(Positioning SRS Resource Set's BWP ID)字段:该字段指示上行(UL)带宽部分(BWP)作为TS38.212[9]中规定的DCI带宽部分指示符字段(DCI bandwidth part indicator field)的代码点。其中,包含激活/未激活的SP Positioning SRS资源集。如果C字段被设置为0,该字段也用于指示包含被Spatial Relation for Resource IDi字段指示的所有资源的BWP的标识。该字段长度为2bit。
C字段:该字段用于指示该字节是否包含Resource Serving Cell ID字段、以及Spatial Relation for Resource IDi字段中的Resource BWP ID字段是否存在。当A/D字段的取值为1时,如果C字段取值为1,则该字节包含Resource Serving Cell ID字段并且Spatial Relation for Resource IDi字段中的Resource BWP ID字段存在;如果C字段取值为0,则不存在。当A/D字段的取值为0时,C字段取值始终为1,表示不包含上述字段。
SUL字段:该字段用于指示该MAC CE支持普通上行链路(NUL,normal uplink)载波配置还是补充的上行链路(SUL,supplementary uplink)载波配置。该字段取值为1时,表示支持SUL载波配置;该字段取值为0时,表示支持NUL载波配置。
Positoining SRS资源集标识(Positoining SRS Resource Set ID)字段:该字段指示激活/未激活的SP Positioning SRS Resource Set,该SP Positioning SRS Resource Set可以为TS 38.331[5]中规定的SRS-PosResourceSetId。该字段的长度为4bit。
资源的空间关系(Spatial Relation for Resource Idi)字段:该字段仅在该MAC CE被用于激活(例如A/字段D取值为1)时存在。M是被Positioning SRS Resource Set ID字段指示的SP Positioning SRS资源集中的Positioning SRS资源数目。Resource Idi有4类空间关系,该4类空间关系可以被F字段(F0和F1)指示。
S字段:该字段用于指示Spatial Relation for Resource Idi字段是否存在。如果S字段取值为1,则Spatial Relation for Resource Idi字段存在,否则,Spatial Relation for Resource Idi字段不存在。
保留(R)字段R:该字段取值为0。
以上为现有的SP Positioning SRS Activation/Deactivation MAC CE中的各字段。本实施例将现有的SP Positioning SRS Activation/Deactivation MAC CE扩展为第一MAC CE,其中包含上述字段。可选地,第一MAC CE包括以下至少一项:

第四指示信息字段,用于指示所述第一MAC CE是否应用于普通上行链路NUL载波配置或补充的上行链路SUL载波配置;如上述SUL字段。
本实施例对上述SP Positioning SRS Activation/Deactivation MAC CE进行扩展,可以在原有字段之后增加路径损耗参考信号信息(Pathloss reference RS info)部分,生成第一MAC CE。该第一MAC CE用于指示positioning SRS的路径损耗参考信号,该路径损耗参考信号可以包括以下几种:
服务小区SSB;
邻小区SSB;
DL PRS;
CSI-RS;
相应的,该第一MAC CE指示以下至少一项:
服务小区SSB的标识;
邻小区SSB的标识和邻小区SSB对应的小区信息;

图6是本申请实施例3的第一MAC CE中,路径损耗参考信号信息(Pathloss reference RS info)部分的结构示意图。如图6所示,该部分包括:
路径损耗参考信号标识(Pathloss Reference RS ID)字段、DL PRS的资源集标识(DL-PRS Resource  Set ID)字段、DL PRS的资源标识(DL-PRS Resource ID)字段和PCI字段。其中,Pathloss Reference RS ID字段是必须包含的字段,用于指示路径损耗参考信号的标识。后三个字段是可选字段。前述各字段与实施例1中相应字段的内容相同,在此不再赘述。
此外,在图5和图6所示的第一MAC CE中,路径损耗参考信号信息(Pathloss reference RS info)部分中的字段,即路径损耗参考信号标识(Pathloss Reference RS ID)字段、DL PRS的资源集标识(DL-PRS Resource Set ID)字段、DL PRS的资源标识(DL-PRS Resource ID)字段和PCI字段均设置于SP Positioning SRS Activation/Deactivation MAC CE的原有字段之后。在本申请的其他实施例中,前述路径损耗参考信号信息(Pathloss reference RS info)部分中的一些字段也可以设置在SP Positioning SRS Activation/Deactivation MAC CE的原有字段之前,本申请实施例对第一MAC CE中各个字段的顺序不做限制。
可选地,本实施例可以将该MAC CE中的任意N个(N为正整数)保留字段作为指示信息(F)字段,用于指示路径损耗参考信号的类型。可选地,该指示信息为上述第一指示信息。该指示信息字段的具体指示方式可以与实施例1的内容相同,在此不再赘述。
综上可见,本申请实施例提出的路径损失参考信息的配置方法,能够实现利用MAC CE配置用于定位的SRS的路径损耗参考信号,节省RRC信令开销,并降低时延。
