技术领域
本公开涉及通信技术领域,尤其涉及一种信息处理方法、装置及可读存储介质。
背景技术
在multi-TRP(multi Transmission and Reception Point,多发送接收点)场景下,终端只维护一个TA(Timing Advance,定时提前),也就是终端只用一个TA对向不同TRP的上行传输进行调整。
图1是终端对两个TRP进行传输的场景,在第一个传输时机终端对TRP1进行传输,使用TA调整上行提前量。在第二个传输时机,终端对TRP2进行传输,也使用TA进行调整。而在实际场景中,终端与TRP2之间的传播时延不同于终端与TRP1之间的路径传播时延。因此,若对于TRP2的上行传输仍旧使用对于TRP1的TA做补偿,将会造成上行传输失步的问题。

下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本公开实施例提供了一种信息处理方法及装置,用以解决上行传输失步的问题。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
参见图2,图2是本公开实施例提供的信息处理方法的流程图,如图2所示,包括以下步骤:
步骤201、网络设备向终端发送第一指示信息,该第一指示信息包括至少两个TRP对应的TA,用于触发终端根据第一指示信息,确定至少两个目标TRP对应的TA;其中,不同的目标TRP对应不同的TA。
具体的,在本公开实施例中,网络设备可向终端发送第一信息,第一信息用于指示至少两个TASG的信息。之后,网络设备向终端发送第二信息,第二信息用于指示至少两个TASG分别对应的TA,或者,第二信息用于指示参考TA以及至少两个TASG所对应的TA之间的第一偏移量;其中,在至少两个TASG中,有至少两个TASG对应的TA不同,或者有至少两个TASG所对应的TA的第一偏移量不同。
考虑到inter-cell(小区间)multi-TRP(多TRP)架构,该第一信息中还可以包含其他小区的PCI(Physical Cell Identifier,物理小区标识符)信息。
其中,参考TA可以是某TASG对应的TA,还可以是一个任选的参考数值。第一偏移量可由终端上报给网络设备,也可由网络设备自行确定。例如,网络设备可从某个数值集合中选择该第一偏移量,或者,根据某种计算方式得到该第一偏移量,在此不对其计算方式进行限定。
例如,假设网络设备通知有4个TASG,其中,至少2个TASG对应的TA不同,或者,有至少两个TASG对应的TA的第一偏移量不同。
其中,每个TASG属于一个TAG(Timing Advance Group,定时提前组),每个TASG维持一个TA。通过TASG可区别TRP,也即,TASG和TRP之间具有一定的对应关系。
第一信息可以是RRC(Radio Resource Control,无线资源控制)配置信息,第二信息可以是用于更新TA的信息,例如,可以是高层信令,如,RRC信令,MAC(Medium Access Control,媒体接入控制)CE(Control Element,控制单元)信令等。
在本公开实施例中,终端包括具有支持多TA能力的终端,以适用于多TRP的场景。
在网络设备侧,可过建立TA与上行传输的关联,指示多个TASG的信息。例如,网络设备可建立TA与上行传输信道(PUCCH(Physical Uplink Control Channel,物理上行控制信道)、PUSCH(Physical Uplink Shared Channel,物理上行共享信道)等)的关联。其中,每个TASG可以与指示上行传输的TCI state、spatial relation info(空间关系信息)关联,也可以与SRS resource set、PUCCH resource关联。考虑到终端具有上行多panel(面板)时的panel切换或者同时传输用例,也可以在关联关系中携带panel第一指示信息,比如capability value set index(能力值设置索引)。又例如,网络设备可建立TA与CORESETPoolindex的关联。具体的,考虑到PUCCH传输与下行PDSCH相关,将TA与调度PDSCH的PDCCH所在的CORESET(Control resource set,控制资源集)中包含的CORESETPoolIndex关联。
以下,详细描述第一指示信息具体实现的各种方式。
一、网络设备建立TA与上行传输的关联
为增加向终端发送第一指示信息的灵活性,TASG的信息可以通过以下至少一种方式指示:
(1)第一信息通过TCI State中的第一目标字段(如TASG标识字段等)指示。
基站通过RRC配置,在TCI state中增加TA-SubgroupId(TASG标识),对应于unified TCI(联合TCI)架构下向某个TRP传输的上行信道。如果一个TCI state没有被配置TASG,使用某个默认的TASG,比如ID最低的TASG。
考虑到inter-cell(小区间)multi-TRP架构,此时与TA subgroup关联的TCI state中的qcl-type D source RS/spatial relation reference RS可以携带non-serving cell ID(非服务小区标识)。
(2)第一信息通过PUCCH-SpatialRelationInfo中的第一目标字段(如TASG标识字段等)指示。
网络设备通过RRC配置在PUCCH-SpatialRelationInfo中增加TA-SubgroupId,对应于向某个TRP传输PUCCH信道。
(3)第一信息通过SRS resource set中的第一目标字段(如TASG标识字段等)指示。
网络设备通过RRC配置在SRS(Sounding Reference Signal,探测参考信号)resource set中增加TA-SubgroupId,通过在DCI(Downlink Control Information,下行控制信息)中的SRI(SRS resource indicator,SRS资源指示)域,对应于指示终端向某个TRP传输PUSCH信道。
(4)第一信息通过PUCCH-Resource中的第一目标字段(如TASG标识字段等)指示。
网络设备通过RRC配置在PUCCH-Resource中增加TA-SubgroupId,对应于调度PUCCH资源对某个TRP进行传输时的TA调整。
(5)第一信息通过PUSCH配置PUSCH-Config中的第一目标字段(如TASG标识字段等)指示。
在实际应用中,网络设备通过RRC配置在PUSCH-Config中增加TA-SubgroupId,对应于调度PUSCH对某个TRP进行传输时的TA调整。
在向终端指示第一信息之后,网络设备可向终端发送第二信息,以更新或指示TA。
具体的,网络设备向终端发送高层信令,第二信息携带在高层信令的第一目标字段(如TASG标识字段等)。例如,第二信息可用于指示至少两个TASG和TA的对应关系。
例如,网络设备可通过携带TA subgroup ID的MAC CE更新TA,比如对于两个TRP,网络设备下发两条MAC-CE信令,具体如表1所示。
表1
具体的,网络设备向终端发送高层信令,高层信令中包括至少两条TA command,至少两条TA command用于指示至少两个TA,或者,至少两条TA command中的第一部分TA command用于指示参考TA,第二部分TA command用于指示TA之间的第一偏移量。
例如,假设有两条TA command,其中一条TA command指示参考TA,另一条TA command用于指示TA之间的第一偏移量。
例如,网络设备在MAC-CE信令中不携带TA subgroup ID,比如在一条MAC CE中携带两条TA command,分别对应于TA#1和TA#2调整,具体如表2所示。
表2
二、网络设备建立TA与CORESETPoolindex的关联的关联
在这种情况下,TA通过PDCCH所在的控制资源集池中的第二目标字段(如CORESETPoolIndex(控制资源集池索引)字段)指示,PDCCH用于调度PDSCH。
具体的,网络设备可向终端发送第三信息,第三信息用于指示至少两个CORESETPoolIndex的信息;之后,网络设备向终端发送第四信息,第四信息用于指示至少两个CORESETPoolIndex信息对应的TA,或者,第四信息用于指示参考TA以及至少两个CORESETPoolIndex对应的TA的第一偏移量。
其中,参考TA可以是某CORESETPoolIndex对应的TA,还可以是一个任选的参考数值。第一偏移量可由终端上报给网络设备,也可由网络设备自行确定。例如,网络设备可从某个数值集合中选择该第一偏移量,或者,根据某种计算方式得到该第一偏移量,在此不对其计算方式进行限定。
其中,第三信息可通过RRC配置信令发送,第四信息可通过高层信令发送。
具体的,网络设备向终端发送高层信令,第四信息携带在高层信令的第二目标字段(如CORESETPoolIndex字段)。例如,第四信息用于指示至少两个CORESETPoolIndex和TA的对应关系。
例如,网络设备通过携带CORESETPoolIndex的MAC CE更新TA,比如对于两个TRP,基站下发两条MAC-CE信令,如表3所示。
表3
在本公开实施例中,网络设备通过第一指示信息可向终端指示至少两个TRP对应的TA,因此,终端可根据该第一指示信息从该TA中为至少两个目TRP选择不同的TA。因此,利用本公开实施例的方案,终端可利用不同的TA对各TRP上行传输进行调整,从而解决了上行传输失步的问题。
可选的,在上述实施例的基础上,网络设备可确定一个或者多个候选TA,该至少两个TRP对应的TA根据一个或者多个候选TA的信息确定。也即,网络设备可从该候选TA中选择至少两个TRP对应的TA。
例如,网络设备接收终端发送的上行参考信号,并根据上行参考信号确定一个或者多个候选TA。可选的,网络设备还可接收终端发送的第二偏移量,第二偏移量为一个或者多个候选TA之间的偏移量,那么,网络设备可根据上行参考信号和第二偏移量,确定确定一个或者多个候选TA。
又例如,网络设备接收终端发送的一个或者多个候选TA的信息,并根据一个或者多个候选TA的信息确定一个或者多个候选TA。其中,一个或者多个候选TA的信息中可包括一个或多个候选TA的值,或者,包括参考TA以及TA之间的偏移量等等。
在实际应用中,终端向网络设备发送上行参考信号。其中,上行参考信号包括preamble(前导码),SRS(Sounding Reference Signal,探测参考信号)或者其他自定义的上行参考信号,比如DMRS(Demodulation Reference Signal,解调参考信号)。具体的,终端可主动触发的上行参考信号发送,或者,网络设备可指示终端进行上行参考信号的发送。其中,终端可发送一次或者多次上行参考信号。若网络设备指示终端进行上行参考信号的发送,网络设备可指示终端发送上行信号的时间频率资源以及上行信号索引等信息。
网络设备接收终端发送的上行参考信号并获取TA。具体的,网络设备可获取一个或者多个TA。其中,网络设备可单独获取每个TA,也可根据前一TA以及TA之间的第二偏移量获取TA,例如,网络设备可在前一TA的基础上加上第二偏移量,而后得到当前需要确定的TA。
其中,第二偏移量可以通过网络设备的估计得到,或者,由终端上报给网络设备。
参见图3,图3是本公开实施例提供的信息处理方法的流程图,如图3所示,包括以下步骤:
步骤301、终端接收网络设备发送的第一指示信息,第一指示信息用于指示至少两个TRP对应的TA;终端根据第一指示信息,确定至少两个目标TRP对应的TA;
或者,
终端根据预定义规则,确定至少两个目标TRP对应的TA;
其中,不同的目标TRP对应不同的TA。
在实际应用中,为了使得网络设备准确的获知终端的能力,终端还可向网络设备发送第二指示信息,第二指示信息用于指示终端具有支持多TA调整的能力。或者,进一步的,终端还可向网络设备发送第三指示信息,第三指示信息用于指示终端具有支持多TA调整的能力以及所支持的TASG的数目。
具体的,终端接收网络设备发送的第一信息,第一信息用于指示至少两个TASG的信息,之后,终端接收网络设备发送的第二信息,第二信息用于指示至少两个TASG分别对应的TA,或者,第二信息用于指示参考TA以及 至少两个TASG所对应的TA之间的第一偏移量,其中,在至少两个TASG中,有至少两个TASG对应的TA不同,或者有至少两个TASG所对应的TA的第一偏移量不同。其中,第一偏移量的含义和获取方式可参照前述方法实施例的描述。
其中,终端接收网络设备发送的第二信息可以为:终端接收网络设备的高层信令,第二信息携带在高层信令的第一目标字段(如TASG标识字段);或者,终端接收网络设备的高层信令,高层信令中包括至少两条TA command,至少两条TA command用于指示至少两个TA,或者,至少两条TA command中的第一部分TA command用于指示参考TA,第二部分TA command用于指示TA之间的第一偏移量。
例如,假设有两条TA command,其中一条TA command指示参考TA,另一条TA command用于指示TA之间的第一偏移量。终端可根据两条TA command所指示的信息,计算出另一TA。
如果终端根据网络设备的第一指示信息确定至少两个目标TRP对应的TA,那么,终端可根据第一指示信息包括的内容的不同,按照不同的方式确定。
如果第一信息通过TCI State中的第一目标字段(如TASG标识字段)指示,那么,终端根据TCI State中的第一目标字段、第二信息,确定至少两个目标TRP对应的TA。
如果第一信息通过PUCCH-SpatialRelationInfo中的第一目标字段(如TASG标识字段)指示,终端根据PUCCH-SpatialRelationInfo中的第一目标字段、第二信息,确定至少两个目标TRP对应的TA。
如果第一信息通过SRS resource set中的第一目标字段(如TASG标识字段)指示,那么,终端根据SRS resource set中的第一目标字段、第二信息,确定至少两个目标TRP对应的TA。
如果第一信息通过PUCCH-Resource中的第一目标字段(如TASG标识字段)指示,那么,终端根据PUCCH-Resource中的第一目标字段、第二信息,确定至少两个目标TRP对应的TA。
如果第一信息通过PUSCH-Config中的第一目标字段(如TASG标识字 段)指示,那么,终端根据PUSCH-Config的第一目标字段、第二信息,确定至少两个目标TRP对应的TA。
在以上几种方式中,具体的,终端按照一定的规则,可根据第一信息可确定TASG与TRP的对应关系。其中,该规则可以是预配置的等。之后,终端可根据第二信息再具体的确定TRP对应的TA。
在上述过程中,若第二信息直接指示的至少两个TASG分别对应的TA,那么,终端可直接根据第一目标字段、以及该第二信息确定出至少两个目标TRP对应的TA。若第二信息用于指示参考TA以及至少两个TASG所对应的TA之间的第一偏移量,那么,终端可根据其中参考TA,以及某个TASG的TA所对应的第一偏移量进行计算,进而计算出该TRP对应的TA。
如果TA通过PDCCH所在的控制资源集池中的第二目标字段(如CORESETPoolIndex字段)指示(PDCCH用于调度PDSCH),那么,在实际应用中,终端接收网络设备发送的第三信息,第三信息用于指示至少两个CORESETPoolIndex的信息,之后,终端接收网络设备发送的第四信息,第四信息用于指示至少两个CORESETPoolIndex对应的TA,或者,第四信息用于指示参考TA以及至少两个CORESETPoolIndex对应的TA的第一偏移量。此时,终端根据第二目标字段(如CORESETPoolIndex字段)、第四信息,确定至少两个目标TRP对应的TA。
具体的,终端按照一定的规则,可根据第三信息可确定CORESETPoolIndex与TRP的对应关系。其中,该规则可以是预配置的等。之后,终端可根据第四信息再具体的确定TRP对应的TA。
在上述过程中,若第四信息直接指示的至少两个CORESETPoolIndex对应的TA,那么,终端可直接根据第二目标字段、以及该第四信息确定出至少两个目标TRP对应的TA。若第四信息用于指示参考TA以及至少两个CORESETPoolIndex对应的TA的第一偏移量,那么,终端可根据其中参考TA,以及某个CORESETPoolIndex的TA所对应的第一偏移量进行计算,进而计算出该CORESETPoolIndex对应的TA。
其中,第二目标字段(如CORESETPoolIndex字段)携带在高层信令中。
此外,终端还可根据预定义规则,确定至少两个目标TRP对应的TA。 其中,预定义规则包括传输时机与TRP的对应关系。此时,终端根据传输时机与TRP的对应关系,以及传输时机与TA的对应关系,确定至少两个目标TRP对应的TA。
例如,利用预定义规则,在某些传输时机(slot(时隙)/subframe(子帧)/symbol(符号))采用某个TA调整,在另外一些传输时机采用另外一个TA进行调整。如表4所示,在奇数slot用TA#1调整,对应于向TRP1进行上行传输时的TA调整,在偶数slot用TA#2调整,对应于向TRP2进行上行传输时的TA调整。
表4
终端收到网络设备指示的TA后,按照网络设备指示的TA计算上行传输的时间调整量,并按照计算得到的时间调整量对上行发送时间进行调整。其中,计算时间调整量的公式如下:
NTA_new=NTA_old+(TA-31)*16*64/2u;TA=0,1,2,3,…,63。
NTA_new表示调整后的时间调整量,NTA_old表示调整之前的时间调整量,u代表子载波间隔。
在本公开实施例中,网络设备通过第一指示信息可向终端指示至少两个TRP对应的TA,因此,终端可根据该第一指示信息从该TA中为至少两个目TRP选择不同的TA。因此,利用本公开实施例的方案,终端可利用不同的TA对各TRP上行传输进行调整,从而解决了上行传输失步的问题。
可选的,在以上实施例的基础上,终端还可向网络设备发送一个或者多个候选TA的信息,用于由网络设备根据一个或者多个候选TA的信息确定至少两个TRP对应的TA。其中,一个或者多个候选TA的信息中可包括一个或多个候选TA的值,或者,包括参考TA以及TA之间的偏移量等等。
例如,终端向网络设备发送上行参考信号,用于由网络设备根据上行参考信号确定候选TA;或者,终端确定一个或者多个候选TA的信息,并向网络设备发送一个或者多个候选TA的信息。
在实际应用中,终端向网络设备发送上行参考信号。其中,上行参考信号包括preamble,SRS或者其他自定义的上行参考信号,比如DMRS。具体 的,终端可主动触发的上行参考信号发送,或者,网络设备可指示终端进行上行参考信号的发送。其中,终端可发送一次或者多次上行参考信号。若网络设备指示终端进行上行参考信号的发送,网络设备可指示终端发送上行信号的时间频率资源以及上行信号索引等信息。为了便于网络设备确定候选TA,终端还可向网络设备发送第二偏移量,第二偏移量为一个或者多个候选TA之间的偏移量。
若终端自行确定一个或者多个候选TA的信息,则终端可根据下行接收时间差确定一个或者多个候选TA的信息。例如,终端可通过对网络设备发送的下行参考信号进行测量,从而确定下行接收时间差,并可将该下行接收时间差作为所述候选TA。
以下以网络设备为基站为例,结合不同的实施例描述本公开的具体实现过程。

NTA_new_2=20+(63-31)*16*64/22=8212(Tc)
这里假设子载波间隔为60KHz(u=2),Nf=4096,Tc=4.07ns。

表6
系统定义对于发送PUCCH1与PUCCH2的TA与调度其发送的DCI所在的PDCCH的CORESET所包含的coresetPoolIndex关联。终端收到基站的指示,确定对应于TRP1传输的PUCCH1和对应于TRP2传输的PUCCH2的TA分别为32和63,终端按照如下公式计算:
NTA_new=NTA_old+(TA-31)*16*64/2u
具体的:
NTA_new_1=10+(32-31)*16*64/22=266(Tc)
NTA_new_2=20+(63-31)*16*64/22=8212(Tc)
这里假设子载波间隔为60KHz(u=2),Nf=4096,Tc=4.07ns。
终端按照计算出的TA调整量在向TRP1进行上行发送时,在下行接收的基础上提前NTA_new_1发送PUCCH,在向TRP2发送时,在下行接收的基础上提前NTA_new_2发送PUCCH。
在本公开的一个实施例中,终端进行能力上报,通知基站所能支持的TA subgroup数目为2。基站通过RRC配置SRS resource set1,SRS resource set2。系统预定义规则为在奇数slot用TA#1调整,对应于向TRP1进行上行传输时的TA调整,在偶数slot用TA#2调整,对应于向TRP2进行上行传输时的TA调整。在第n时隙,基站下发DCI,通过DCI中的SRS resource set域指示通过向两个TRP同时传输PUSCH,PUSCH重复发送次数为4,重复pattern#1#2#1#2,对应于在奇数slot所用波束为SRI1域指示,在偶数slot所用波束为SRI2域指示,对应向TRP1和TRP2发送PUSCH信息。基站在第n+3时隙下发更新TA的MAC CE,如表7所示。
表7
终端收到基站的指示,按照预定义规则确定两个TA分别为32和63,终端按照如下公式计算:
NTA_new=NTA_old+(TA-31)*16*64/2u
具体的:
NTA_new_1=10+(32-31)*16*64/22=266(Tc)
NTA_new_2=20+(63-31)*16*64/22=8212(Tc)
这里假设子载波间隔为60KHz(u=2),Nf=4096,Tc=4.07ns。
终端按照计算出的TA调整量在奇数时隙向TRP1进行上行发送时,在下行接收的基础上提前NTA_new_1发送PUSCH,在偶数时隙向TRP2发送时,在下行接收的基础上提前NTA_new_2发送PUSCH。
在本公开的一个实施例中,终端在初始接入时,获取RACH(Random Access Channel,随机接入信道)信道配置,并按照RACH信道配置在PRACH(Physical Random Access Channel,物理随机接入信道)的发送时刻(RO)确定发送preamble的时间频率资源,进行上行接入。
其中,终端可通过以下方式获取PRACH索引:
SIB1->UplinkConfigCommon->initialUplinkBWP->RACH-ConfigCommon
->RACH-ConfigGeneric中的prach-ConfigurationIndex;
终端可通过以下方式获取发送时刻:通过RACH-ConfigCommon中的ssb-perRACH-OccasionAndCB-PreamblesPerSSB获取。
之后,终端在RAR(Random AccessResponse,随机接入响应)window(窗口)内接收基站回复的RAR MAC(Medium Access Control,媒体接入控制)PDU(Protocol Data Unit,协议数据单元)。在RAR MAC PDU中包括的TA command承载了上行同步所用TA-TA1。
终端根据基站在TA command中的指示计算绝对时间调整量NTA,并在下行接收定时的基础上对上行发送MSG3的PUSCH(Physical Uplink Shared Channel,物理上行共享信道)进行调整,也即在下行接收的PDSCH(Physical downlink shared channel,物理下行共享信道)的基础上提前NTA时刻发送MSG3。
基站下发PDCCH(Physical downlink control channel,物理下行控制信道)order(DCI format 1_0),指示终端朝TRP2发送Preamble2。在这个过程中,也包括基站下发的其他层1以及高层信令,指示终端在指定的时间频率资源上用指定的波束发送SRS。
基站接收终端发送的preamble 2或SRS,并估算朝向第二个TRP进行上行发送的TA-TA2,或者,TA-TA2与TA-TA1之间的偏移量。
其中,TA-TA2与TA-TA1之间的偏移量也可以通过终端上报的方式获得。具体的,终端对下行参考信号接收并估计来自于两个TRP的下行信号接收时间差从而得到该偏移量,终端并将得到的偏移量发送给基站。
基站指示终端进行上行发送时的TA-TA1,TA-TA2,其中,指示方式可参照前述实施例的描述。当然,基站也可以指示其中的一个TA以及两个TA之间的偏移量。
终端接收到基站指示的TA,用对应的TA值对上行传输时间进行调整。其中,计算和调整方法与前述实施例中描述的原理相同。
通过以上描述可以看出,利用本公开实施例的方案,解决了利用同一个TA对所有TRP做补偿时带来的上行失步问题,从而弥补了上行性能损失。
