技术领域
本公开实施例涉及无线通信技术领域,尤其涉及一种同步信号块的处理方法、同步信号块的指示方法及装置。
背景技术
新无线(New Radio,简称NR)系统的设计中,基站需要向终端发送同步信号块(Synchronous Signal Block,简称SSB)以供终端进行同步、系统信息获取、测量等。多个SSB组成一个SSB突发集(SS burst set)。一个SSburst set中最大包含的SSB数目与网络使用的载波频率相关,其中:
●频率小于3千兆赫(GHz)时,一个SS burst set中最多可以包含4个SSB;
●载波频率范围为3GHz到6GHz时,一个SS burst set中最多可以包含8个SSB;
●载波频率范围为6GHz以上时,一个SS burst set中最多可以包含64个SSB。
无论一个SS burst set中包含多少SSB,基站都需要在一个5毫秒(ms)的时间窗内发送完。然而基站在5ms时间窗内实际传输的SSB数目可能会小于该频段上一个SS burst set中最多可以包含的SSB数目。因而,基站需要在发送完SSB之后,向终端指示发送了哪些SSB。目前,5G讨论的结果是,基站可以通过系统信息和无线资源控制信令(Radio Resource Control,简称RRC)指示终端:向终端发送了哪些SSB。终端可以根据接收到的同步信号块的指示信息,判定接收数据的时频资源位置。
然而,目前的讨论中,当终端根据接收到的同步信号块的指示信息判断 接收数据的时频资源位置时,并未考虑,控制资源组(Control resource set,简称CORESET)的复用情况,这导致终端对接收数据的时频资源位置的判断不准确。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例的附图,对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。基于所描述的本公开的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本公开保护的范围。
实施例一
请参考图1,图1为本公开实施例一的同步信号块的指示方法的流程示意图,该方法应用于基站,包括:
步骤11:发送同步信号块;
基站发送同步信号块是以广播的方式发送。
步骤12:发送同步指示信息,所述同步指示信息用于指示所述基站发送的同步信号块,所述同步指示信息为第一指示信息,或者,所述同步指示信息包括第一指示信息和第二指示信息,所述第一指示信息由所述基站通过系统信息发送,所述第二指示信息由所述基站通过RRC信令发送。
本公开实施例中,可选的,所述系统信息可以为剩余最小系统信息(Remaining Minimum System Information,简称RMSI)。当然,在本公开的其他一些实施例中,也不排除采用其他系统信息发送所述第一指示信息。
本公开实施例中,不同终端对应的第二指示信息中指示的所述基站发送的同步信号块相同或不同。
本公开实施例中,基站向终端发送同步指示信息,以使得终端能够根据所述同步指示信息中指示的所述基站发送的同步信号块执行相应的操作。
例如,所述相应的操作可以包括以下至少之一:判断接收数据的时频资源位置和解速率匹配、对同步信号块进行测量,以及对同步信号块进行测量并用于无线链路监控等。
所述接收数据可以包括:RMSI CORESET、RMSI PDSCH、UE-specific CORESET、UE-specific PDSCH、common PDSCH以及其他CORESET中的至少之一。
其中,其他CORESET为不同于RMSI CORESET、UE-specific CORESET的CORESET,或者其他CORESET为除RMSI CORESET、UE-specific CORESET之外的CORESET。例如RACH(Random Access Channel,随机接入信道)message的CORESET,广播的OSI的CORESET,Paging的CORESET等。
所述common PDSCH为不同于RMSI PDSCH、UE-specific PDSCH的PDSCH,或者common PDSCH为除所述RMSI PDSCH、UE-specific PDSCH之外的PDSCH。例如RACH message的PDSCH,广播的OSI的PDSCH,Paging的PDSCH等。
其中,RACH message包括RACH过程中的RAR(Random Access Response,随机接入响应,即Msg2)和Contention Resolution(竞争解决,即Msg4)。
其中,PDSCH为物理下行共享信道(Physical Downlink Shared Channel)。
其中,UE-specific PDSCH是指使用终端专用PDSCH。
本公开实施例中,基站向终端发送同步指示信息,以辅助终端获得正确的基站实际发送的同步信号块,从而使得终端能够正确地判断接收数据的时频资源位置和解速率匹配、测量或无线链路监控等。
在载波频率范围为6GHz以上的频段,基站通过RMSI发送的第一指示信息指示发送的同步信号块时,可以采用一个8bit的组bitmap+一个8bit的组 内bitmap的方式指示。组bitmap指示基站传输了哪些同步信号块组,组内bitmap指示基站传输了这些同步信号块组内的哪些同步信号块,在指示信息中,每个组内传输的同步信号块是相同的。举例来说:载波频率范围为6GHz以上时,一个SS burst set中最多可以包含64个同步信号块,将这64个可能传输的同步信号块分为8个组,假设组bitmap为“11000000”指示基站传输了第一、二个同步信号块组,组内bitmap为“11110000”,表示基站传输了第一、二个组内的前四个同步信号块,即指示一共传输了2x4=8个同步信号块。由于在指示信息中,每个组内传输的同步信号块的指示信息是相同的,因而无法指示组内传输的同步信号块不同的情况,这导致基站在RMSI中指示的同步信号块可能与基站实际发送的同步信号块并不相符。举例来说,第一个同步信号块组传输了前四个同步信号块,第二个同步信号块组只传输了前两个同步信号块,然而组内bitmap指示为“11110000”,从而使得RMSI中指示的同步信号块(8个同步信号块)可能与基站实际发送的同步信号块(6个)并不相符。而,终端接收到基站在RMSI中指示的同步信号块之后,则判定基站实际发送的同步信号块为指示的同步信号块,并基于指示的同步信号块执行测量、无线链路监控、数据接收和发送等处理,如果基站指示的同步信号块的信息不准确,会导致终端可能对一些无法检测到的同步信号块也尝试进行搜索和检测,将造成没有必要的耗电,或者,会导致终端可能对一些实际发送的同步信号块没有搜索和检测,从而导致测量结果不准,或者链路监控结果不准,或者无法保证终端正确解速率匹配和接收PDSCH/CORESET等问题。
本公开实施例中,可选的,所述第二指示信息可以采用全位图(Full bitmap)的方式指示所述基站发送的同步信号块。即一个SS burst set中最多可以包含L个同步信号块(L=4/8/64)时,采用长度为L的bitmap指示哪些同步信号块实际传输。举例来说,在载波频率范围为6GHz以上的频段,可以采用64bit的bitmap指示所述基站发送的同步信号块。由于所述第二指示信息采用全位图的方式指示所述基站发送的同步信号块,因而指示的更加准确,减少因基站通过RMSI指示的同步信号块的信息不准确,导致终端可能对一些无法检测到的同步信号块也尝试进行搜索和检测,造成没有必要的耗电,或者,导 致终端可能对一些实际发送的同步信号块没有搜索和检测,从而导致测量结果不准,或者链路监控结果不准,或者无法保证终端正确解速率匹配和接收PDSCH/CORESET等问题。
当基站通过多个波束发送同步信号块时,不同的同步信号块可能和不同的波束相关联,基站可以根据需求灵活地配置波束和同步信号块之间的映射关系,也就是说,不同的同步信号块可能在不同的波束上发送,其中有些波束的方向完全无法覆盖终端,对应的这些波束上传输的同步信号块也无法被该终端搜索到。此时终端如果对基站通过系统信息指示的同步信号块均进行搜索和检测,意味着终端可能对一些无法检测到的同步信号块也尝试进行了搜索和检测,将造成没有必要的耗电。本公开实施例中,基站可以采用第二指示信息更加准确地指示基站在不同波束上发送的同步信号块,减少因基站通过系统信息指示的同步信号块的信息不准确,导致终端可能对一些无法检测到的同步信号块也尝试进行搜索和检测,造成没有必要的耗电。
同步信号块和终端专用PDSCH/CORESET可能在相同的时频资源上传输,此时,基站可以将同步信号块和终端专用PDSCH/CORESET进行空分复用,通过不同的波束传输出去,从而减小互相干扰。此时终端需要知道基站实际传输的同步信号块的信息,来保证终端和基站对基站如何做速率匹配的方式理解一致。
因而,在本公开的一些可选实施例中,所述发送同步信号块的步骤可以包括:
在相同的时频资源上,通过覆盖第一终端的第一波束发送同步信号块,以及通过覆盖第二终端的第二波束向所述第二终端发送PDSCH数据和/或CORESET;
所述发送同步指示信息的步骤包括:
通过无线资源控制信令向所述第一终端和第二终端发送所述第二指示信息,所述第一终端对应的第二指示信息指示所述基站通过所述第一波束在当前时频资源上发送的同步信号块,所述第二终端对应的第二指示信息中指示所述基站未通过所述第二波束在当前时频资源上发送同步信号块;或者,所述第一终端和第二终端对应的第二指示信息中均指示所述基站在当前时频资 源上发送的同步信号块。
本公开实施例中,当同步信号块和终端专用PDSCH/CORESET在相同的时频资源上传输并空分复用时,可以通过第二指示信息更加准确地向终端指示基站在当前时频资源上发送的同步信号块,避免因终端无法获取基站实际发送的同步信号块而导致终端解速率匹配错误的问题。
5G系统引入了载波聚合(Carrier Aggregation,简称CA),以提高吞吐率和资源利用率,载波集合是将两个或更多个载波单元(Component Carrier,简称CC)聚合在一起以支持更大的传输带宽,其中,一个载波单元对应一个独立的小区(Cell),在CA场景中可以分为以下几种类型的Cell:主小区(Primary Cell,简称PCell)和辅小区(Secondary Cell,简称SCell)。主小区工作在主频带上,为初始连接建立/连接重建时连接的cell。辅小区工作在辅频带上,用于为终端提供业务传输所需的额外无线资源,终端不需要初始接入Scell。
在载波聚合场景下,辅小区同样会发送同步信号块,然而终端不会在辅小区上尝试接入,因此不会去读取辅小区的同步信号块,从而无法通过系统信息发送的第一指示信息获得实际传输的同步信号块的信息。第一指示信息中只指示主小区发送的同步信号块。当终端和辅小区上发生下行数据调度和传输的时候,可能因为不知道辅小区实际传输的同步信号块的信息而导致解速率匹配错误。因而,在本公开的一些实施例中,可选的,所述同步信号块的指示方法还包括:
通过无线资源控制信令向终端发送第三指示信息,所述第三指示信息用于指示辅小区发送的同步信号块。
从而,使得终端能够获知辅小区发送的同步信号块,当终端和辅小区上发生下行数据调度和传输的时候,能够正确的解速率匹配。
终端在接收到同步信号块之后,可以对同步信号块进行测量并上报测量结果,基站根据测量结果进行小区切换或者小区重选。为了使得终端能够获得更加准确的同步信号块的信息以用于测量,在本公开的一些实施例中,可选的,所述同步信号块的指示方法还包括:
通过无线资源控制信令向终端发送第四指示信息,所述第四指示信息用 于指示终端需要测量的同步信号块。
从而辅助终端对同步信号块进行测量,有利于降低同步信号块盲检和测量的时间,实现终端节能。
所述第四指示信息中指示的同步信号块可以是SMTC(SS block based RRM measurement timing configuration,基于同步信号块的无线资源管理测量时间配置)测量时长内的同步信号块,也可以不都是SMTC测量时长内的同步信号块。
本公开实施例中,不同终端对应的所述第四指示信息中指示的基站发送的SMTC测量时长内终端需要测量的同步信号块可以相同也可以不同。
本公开实施例中,所述第四指示信息可以采用全位图的方式指示终端需要测量的同步信号块。
本公开实施例中,当所述第四指示信息用于服务小区时(即对应的SMTC用于服务小区测量)时,第四指示信息可能和所述第二指示信息相同或不同,也可能和所述第三指示信息相同或不同。例如,当对应的SMTC测量的邻小区和本小区同频时,第四指示信息有可能为本小区和邻小区第二指示信息合集,也有可能为该合集的子集,当SMTC测量的邻小区和本小区异频时,第四指示信息有可能和第二指示信息一样,也有可能为第二指示信息的子集。
此外,本公开实施例中,如果基站没有给连接态的终端配置该指示信息,终端则默认测量SMTC周期内所有同步信号块。对于空闲态的终端,基站不配置该第四指示信息,终端默认测量SMTC周期内所有同步信号块。
同步信号块还可以用于无线链路监控(Radio Link Monitoring,简称RLM),为了使得终端能够获得更加准确的同步信号块的信息以用于无线链路监控,在本公开的一些实施例中,可选的,所述同步信号块的指示方法还包括:
通过无线资源控制信令向终端发送第五指示信息,所述第五指示信息用于指示终端需要测量且用于无线链路监控的同步信号块。
在一些实施例中,所述第五指示信息采用位图的方式指示需要测量且用于无线链路监控的同步信号块,可选的,采用全位图的方式指示需要测量且用于无线链路监控的同步信号块,以使得指示的需要测量且用于无线链路监 控的同步信号块更加准确。
在另外一些实施例中,所述第五指示信息中指示需要测量且用于无线链路监控的同步信号块的数目,例如,指示需要测量且用于无线链路监控的同步信号块为实际接收到的同步信号块的前两个,以减少第五指示信息所占用的比特。
在另外一些实施例中,所述第五指示信息中指示需要测量且用于无线链路监控的同步信号块的时间序号(time index)。
实施例二
请参考图2,本公开的实施例二还提供一种同步信号块的处理方法,应用于终端,包括:
步骤21:接收基站发送的同步信号块;
基站发送同步信号块是以广播的方式发送。
步骤22:接收所述基站发送的同步指示信息,所述同步指示信息用于指示所述基站发送的同步信号块,所述同步指示信息为第一指示信息,或者,所述同步指示信息包括第一指示信息和第二指示信息,所述第一指示信息由所述基站通过系统信息发送,所述第二指示信息由所述基站通过无线资源控制信令发送;
本公开实施例中,可选的,所述系统信息可以为RMSI。当然,在本公开的其他一些实施例中,也不排除采用其他系统信息发送所述第一指示信息。
步骤23:确定RMSI CORESET、UE-specific CORESET和除RMSI CORESET、UE-specific CORESET之外的其他CORESET的复用信息;
步骤24:根据所述复用信息和所述同步指示信息,判定接收数据的时频资源位置。
所述接收数据可以包括:RMSI CORESET、RMSI PDSCH、UE-specific CORESET、UE-specific PDSCH、common PDSCH以及其他CORESET中的至少之一。
其中,其他CORESET为不同于RMSI CORESET、UE-specific CORESET的CORESET,或者其他CORESET为除RMSI CORESET、UE-specific CORESET之外的CORESET。例如RACH message的CORESET,广播的OSI 的CORESET,Paging的CORESET等。
所述common PDSCH为不同于RMSI PDSCH、UE-specific PDSCH的PDSCH,或者common PDSCH为除所述RMSI PDSCH、UE-specific PDSCH之外的PDSCH,例如RACH message的PDSCH,广播的OSI的PDSCH,Paging的PDSCH等。
其中,RACH message包括RACH过程中的RAR(Random Access Response,随机接入响应,即Msg2)和Contention Resolution(竞争解决,即Msg4)。
其中,UE-specific PDSCH是指使用终端专用PDSCH。
本公开实施例中,终端可以根据基站发送的同步指示信息以及CORESET的复用情况,以更加准确地判断接收数据的资源位置。
物理信道的承载能力是有限的,在发送数据前基站要进行速率匹配的处理,即对传输信道上的比特进行重复或者被打孔,使得传输的数据匹配物理信道的承载能力。对于下行,终端为了进行正常的下行信道接收,需要进行解速率匹配,即恢复被打孔的比特或者去掉重复的比特,从而获得基站速率匹配之前的完整数据流。LTE Rel-10中,基站在将PDSCH数据映射到物理资源上时,会避开基于小区的参考信号(CSI-RS)所占据的资源单位(Resource Element,简称RE),即这些RE要被CSI-RS使用而不能被PDSCH所使用。Rel-10的终端在解速率匹配时,会假定CSI-RS所占的RE并不被PDSCH数据所占用。基站和终端双方需要对基站如何做速率匹配的方式理解一致。NR中同样需要进行速率匹配和解速率匹配。类似地,基站在将终端专用PDSCH/CORESET数据映射到物理资源上时,也需要考虑避开同步信号块占据的RE。终端在解速率匹配时,会假定同步信号块所占的RE并不被终端专用PDSCH/CORESET数据所占用。
为了正确解速率匹配,本公开的一些实施例中,可选的,所述同步指示信息可以包括第二指示信息,所述第二指示信息用于指示所述基站发送的同步信号块,其中,不同终端对应的辅助指示信息中指示的所述基站发送的同步信号块相同或不同。
本公开实施例中,可选的,所述第二指示信息可以采用全位图(Full bitmap) 的方式指示所述基站发送的同步信号块。由于所述第二指示信息采用全位图的方式指示所述基站发送的同步信号块,因而指示的更加准确,减少因基站通过系统信息指示的同步信号块的信息不准确,导致终端可能对一些无法检测到的同步信号块也尝试进行搜索和检测,造成没有必要的耗电,或者,导致终端可能对一些实际发送的同步信号块没有搜索和检测,导致测量结果不准,或者链路监控结果不准,或者无法保证终端正确解速率匹配和接收PDSCH/CORESET等问题。
本公开实施例中,基站会给终端配置三种CORESET(RMSI CORESET、UE-specific CORESET和其他CORESET)的配置信息,配置信息包括对应CORESET的时频域等信息,从而终端能够根据该配置信息确定三种CORESET之间的复用关系,确定RMSI CORESET、UE-specific CORESET和其他CORESET的复用信息。
在本公开的一些实施例中,针对RMSI CORESET、其他CORESET和UE-specific CORESET中的其中之一与其他另外两个均不复用的情况:
当所述同步指示信息包括第一指示信息和第二指示信息时,所述根据所述复用信息和所述同步指示信息,判定接收数据的时频资源位置的步骤可以包括:

在UE-specific CORESET与其他CORESET不复用,且UE-specific CORESET与RMSI CORESET也不复用的情况下,针对UE-specific PDSCH和UE-specific CORESET:判定所述第二指示信息中指示的所述基站发送的同步信号块为所述基站实际发送的同步信号块,并判定UE-specific PDSCH 和UE-specific CORESET在所述第二指示信息指示的所述基站发送同步信号块的时频资源位置之外的时频资源位置上传输;
在其他CORESET与UE-specific CORESET不复用,且其他CORESET与RMSI CORESET也不复用的情况下,针对common PDSCH和其他CORESET:判定所述第一指示信息中指示的所述基站发送的同步信号块为所述基站实际发送的同步信号块,并判定common PDSCH和其他CORESET在第一指示信息指示的所述基站发送同步信号块的时频资源位置之外的时频资源位置上传输。

在其他CORESET与UE-specific CORESET不复用,且其他CORESET与RMSI CORESET也不复用的情况下,针对common PDSCH和其他CORESET:判定所述第一指示信息中指示的所述基站发送的同步信号块为所述基站实际发送的同步信号块,并判定common PDSCH和其他CORESET在所述第一指示信息指示的所述基站发送同步信号块的时频资源位置之外的时 频资源位置上传输。

在载波聚合场景下,辅小区同样会发送同步信号块,然而终端不会在辅小区上尝试接入,因此不会去读取辅小区的同步信号块,从而无法通过系统信息发送的第一指示信息获得实际传输的同步信号块的信息。第一指示信息中只指示主小区发送的同步信号块。当终端和辅小区上发生下行数据调度和传输的时候,可能因为不知道辅小区实际传输的同步信号块的信息而导致解速率匹配错误。因而,在本公开的一些实施例中,可选的,所述同步信号块的处理方法还包括:

当所述终端需要在辅小区的时频资源上进行业务传输时,判定辅小区载波上的所述接收数据在辅小区载波上所述第三指示信息指示的所述辅小区发送同步信号块的时频资源位置之外的时频资源位置上传输。
从而,使得终端能够获知辅小区发送的同步信号块,当终端和辅小区上发生下行数据调度和传输的时候,能够正确的解速率匹配。
在本公开的一些实施例中,所述同步信号块的处理方法还包括:
当所述同步指示信息为第一指示信息,且未接收到所述基站通过无线资源控制信令向终端发送的第三指示信息时,判定所述第三指示信息中指示的辅小区发送的同步信号块与所述第一指示信息中指示的基站发送的同步信号块相同,判定在辅小区载波上的所述接收数据在辅小区载波上所述第一指示信息指示的所述基站发送同步信号块的时频资源位置之外的时频资源位置上传输;或者

接收所述基站通过无线资源控制信令发送的第四指示信息,所述第四指示信息用于指示终端需要测量的同步信号块;
在SMTC测量时长内对所述第四指示信息中指示的同步信号块进行测量。
也就是说,对所述第四指示信息中指示的同步信号块中位于SMTC测量 时长内的同步信号块进行测量,而对所述第四指示信息中指示的同步信号块中不位于SMTC测量时长内的同步信号块不进行测量,从而辅助终端对同步信号块进行测量,有利于降低同步信号块盲检和测量的时间,实现终端节能。
本公开实施例中,所述方法还可以包括:

本公开实施例中,不同终端对应的所述第四指示信息中指示的基站发送的终端需要测量的同步信号块可以相同也可以不同。
本公开实施例中,所述第四指示信息可以采用全位图的方式指示终端需要测量的同步信号块。
本公开实施例中,当所述第四指示信息用于服务小区时(即对应的SMTC用于服务小区测量)时,第四指示信息可能和所述第二指示信息相同或不同,也可能和所述第三指示信息相同或不同。例如,当对应的SMTC测量的邻小区和本小区同频时,第四指示信息有可能为本小区和邻小区第二指示信息合集,也有可能为该合集的子集。当SMTC测量的邻小区和本小区异频时,第四指示信息有可能和第二指示信息一样,也有可能为第二指示信息的子集。
此外,本公开实施例中,如果基站没有给连接态的终端配置该指示信息,终端则默认测量SMTC周期内所有同步信号块。对于空闲态的终端,基站不配置该第四指示信息,终端默认测量SMTC周期内所有同步信号块。

在一些实施例中,所述第五指示信息采用位图的方式指示需要测量且用于无线链路监控的同步信号块,可选的,采用采用全位图的方式指示需要测量且用于无线链路监控的同步信号块,以使得指示的需要测量且用于无线链路监控的同步信号块更加准确。
在另外一些实施例中,所述第五指示信息中指示需要测量且用于无线链路监控的同步信号块的数目,例如,指示需要测量且用于无线链路监控的同步信号块为实际接收到的同步信号块的前两个,以减少第五指示信息所占用的比特。
在另外一些实施例中,所述第五指示信息中指示需要测量且用于无线链路监控的同步信号块的时间序号。

基站广播RMSI和OSI,并给某个终端发送UE-specific CORESET和UE-specific PDSCH。该UE-specific CORESET和OSI CORESET复用,且和RMSI CORESET复用。基站通过RMSI发送第一指示信息,指示11110000,即指示基站发送了SSB1、SSB2、SSB3和SSB4。终端在接入小区的时候会读取RMSI从而获得第一指示信息。基站通过RRC发送第二指示信息,指示11111000,即指示基站发送了SSB1、SSB2、SSB3、SSB4和SSB5。其中SSB4的时频资源和该复用的CORESET调度的common PDSCH的时频资源重叠,SSB5的时频资源和该复用的CORESET调度的UE-specific PDSCH的时频资源重叠。

实施例二十四
基于同一发明构思,请参考图7,本公开的实施例二十四还提供一种基站60,该基站包括:
第一发送模块61,用于发送同步信号块;第一发送模块151发送同步信号块是以广播的方式发送。
第二发送模块62,用于发送同步指示信息,所述同步指示信息用于指示所述基站发送的同步信号块,所述同步指示信息为第一指示信息,或者,所述同步指示信息包括第一指示信息和第二指示信息,所述第一指示信息由所述基站通过系统信息发送,所述第二指示信息由所述基站通过无线资源控制信令发送。
其中,第一发送模块61和第二发送模块62可以为相互独立的模块,可 以采用一个模块实现。
本公开实施例中,可选的,所述系统信息可以为剩余最小系统信息(Remaining Minimum System Information,简称RMSI),当然,在本公开的其他一些实施例中,也不排除采用其他系统信息发送所述第一指示信息。
本公开实施例中,不同终端对应的第二指示信息中指示的所述基站发送的同步信号块相同或不同。
本公开实施例中,基站向终端发送同步指示信息,以使得终端能够根据所述同步指示信息中指示的所述基站发送的同步信号块执行相应的操作。
例如,所述相应的操作可以包括以下至少之一:判断接收数据的时频资源位置、对同步信号块进行测量,以及对同步信号块进行测量并用于无线链路监控等。
所述接收数据可以包括:RMSI CORESET、RMSI PDSCH、UE-specific CORESET、UE-specific PDSCH、common PDSCH以及其他CORESET中的至少之一。
其中,其他CORESET为不同于RMSI CORESET、UE-specific CORESET的CORESET,或者其他CORESET为除RMSI CORESET、UE-specific CORESET之外的CORESET。例如RACH message的CORESET,广播的OSI的CORESET,Paging的CORESET等。
所述common PDSCH为不同于RMSI PDSCH、UE-specific PDSCH的PDSCH,或者common PDSCH为除所述RMSI PDSCH、UE-specific PDSCH之外的PDSCH,例如RACH message的PDSCH,广播的OSI的PDSCH,Paging的PDSCH等。
其中,RACH message包括RACH过程中的RAR(Random Access Response,随机接入响应,即Msg2)和Contention Resolution(竞争解决,即Msg4)。
其中,PDSCH为物理下行共享信道(Physical Downlink Shared Channel)。
其中,UE-specific PDSCH是指使用终端专用PDSCH。
本公开实施例中,基站向终端发送同步指示信息,以辅助终端获得正确的基站实际发送的同步信号块,从而使得终端能够正确地判断接收数据的时 频资源位置、测量或无线链路监控等。
本公开实施例中,可选的,所述第二指示信息可以采用全位图(Full bitmap)的方式指示所述基站发送的同步信号块。即一个SS burst set中最多可以包含L个同步信号块(L=4/8/64)时,采用长度为L的bitmap指示哪些同步信号块实际传输。举例来说,在载波频率范围为6GHz以上的频段,可以采用64bit的bitmap指示所述基站发送的同步信号块。由于所述第二指示信息采用全位图的方式指示所述基站发送的同步信号块,因而指示的更加准确,减少因基站通过RMSI指示的同步信号块的信息不准确,导致终端可能对一些无法检测到的同步信号块也尝试进行搜索和检测,造成没有必要的耗电,或者,导致终端可能对一些实际发送的同步信号块没有搜索和检测,从而导致测量结果不准,或者无法保证终端正确解速率匹配和接收PDSCH/CORESET等问题。
同步信号块和终端专用PDSCH/CORESET可能在相同的时频资源上传输,此时,基站可以将同步信号块和终端专用PDSCH/CORESET进行空分复用,通过不同的波束传输出去,从而减小互相干扰。此时终端需要知道基站实际传输的同步信号块的信息,来保证终端和基站对基站如何做速率匹配的方式理解一致。
因而,在本公开的一些可选实施例中:
所述第一发送模块61,用于在相同的时频资源上,通过覆盖第一终端的第一波束发送同步信号块,以及通过覆盖第二终端的第二波束向所述第二终端发送PDSCH数据和/或CORESET;
所述第二发送模块62,用于通过无线资源控制信令向所述第一终端和第二终端发送所述第二指示信息,所述第一终端对应的第二指示信息指示所述基站通过所述第一波束在当前时频资源上发送的同步信号块,所述第二终端对应的第二指示信息中指示所述基站未通过所述第二波束在当前时频资源上发送同步信号块;或者,所述第一终端和第二终端对应的第二指示信息中均指示所述基站在当前时频资源上发送的同步信号块。
本公开实施例中,当同步信号块和终端专用PDSCH/CORESET在相同的时频资源上传输并空分复用时,可以通过第二指示信息更加准确地向终端指示基站在当前时频资源上发送的同步信号块,避免因终端无法获取基站实际 发送的同步信号块而导致终端解速率匹配错误的问题。
在载波聚合场景下,辅小区同样会发送同步信号块,然而终端不会在辅小区上尝试接入,因此不会去读取辅小区的同步信号块,从而无法通过系统信息获得实际传输的同步信号块的信息。当终端和辅小区上发生下行数据调度和传输的时候,可能因为不知道辅小区实际传输的同步信号块的信息而导致解速率匹配错误。因而,在本公开的一些实施例中,可选的,所述基站还包括:
第三发送模块,用于通过无线资源控制信令向终端发送第三指示信息,所述第三指示信息用于指示辅小区发送的同步信号块。
从而,使得终端能够获知辅小区发送的同步信号块,当终端和辅小区上发生下行数据调度和传输的时候,能够正确的解速率匹配。
终端在接收到同步信号块之后,可以对同步信号块进行测量并上报测量结果,基站根据测量结果进行小区切换或者小区重选。为了使得终端能够获得更加准确的同步信号块的信息以用于测量,在本公开的一些实施例中,可选的,所述基站还包括:
第四发送模块,用于通过无线资源控制信令向终端发送第四指示信息,所述第四指示信息用于指示终端需要测量的同步信号块。
从而辅助终端对同步信号块进行测量,有利于降低同步信号块盲检和测量的时间,实现终端节能。
本公开实施例中,不同终端对应的所述第四指示信息中指示的基站发送的SMTC测量时长内终端需要测量的同步信号块可以相同也可以不同。
本公开实施例中,所述第四指示信息可以采用全位图的方式指示SMTC测量时长内终端需要测量的同步信号块。
本公开实施例中,当所述第四指示信息用于服务小区时(即对应的SMTC用于服务小区测量)时,第四指示信息可能和所述第二指示信息相同或不同,也可能和所述第三指示信息相同或不同。例如,当对应的SMTC测量的邻小区和本小区同频时,第四指示信息有可能为本小区和邻小区第二指示信息合集,也有可能为该合集的子集。当SMTC测量的邻小区和本小区异频时,第四指示信息有可能和第二指示信息一样,也有可能为第二指示信息的子集。
此外,本公开实施例中,如果基站没有给连接态的终端配置该指示信息,终端则默认测量SMTC周期内所有同步信号块。对于空闲态的终端,基站不配置该第四指示信息,终端默认测量SMTC周期内所有同步信号块。
同步信号块还可以用于无线链路监控,为了使得终端能够获得更加准确的同步信号块的信息以用于无线链路监控,在本公开的一些实施例中,可选的,所述基站还包括:
第五发送模块,用于通过无线资源控制信令向终端发送第五指示信息,所述第五指示信息用于指示终端需要测量且用于无线链路监控的同步信号块。
在一些实施例中,所述第五指示信息采用位图的方式指示需要测量且用于无线链路监控的同步信号块,可选的,采用全位图的方式指示需要测量且用于无线链路监控的同步信号块,以使得指示的需要测量且用于无线链路监控的同步信号块更加准确。
在另外一些实施例中,所述第五指示信息中指示需要测量且用于无线链路监控的同步信号块的数目,例如,指示需要测量且用于无线链路监控的同步信号块为实际接收到的同步信号块的前两个,以减少第五指示信息所占用的比特。
在另外一些实施例中,所述第五指示信息中指示需要测量且用于无线链路监控的同步信号块的时间序号。
本公开实施例中的基站可以是全球移动通讯(Global System of Mobile communication,简称GSM)或码分多址(Code Division Multiple Access,简称CDMA)中的基站(Base Transceiver Station,简称BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,简称WCDMA)中的基站(NodeB,简称NB),还可以是LTE中的演进型基站(Evolutional Node B,简称eNB或eNodeB),或者中继站或接入点,或者未来5G网络中的基站等,在此并不限定。

所述common PDSCH为不同于RMSI PDSCH、UE-specific PDSCH的PDSCH,或者common PDSCH为除所述RMSI PDSCH、UE-specific PDSCH之外的PDSCH,例如RACH message的PDSCH,广播的OSI的PDSCH,Paging的PDSCH等。
其中,RACH message包括RACH过程中的RAR(Random Access Response,随机接入响应,即Msg2)和Contention Resolution(竞争解决,即Msg4)。

本公开实施例中,可选的,所述第二指示信息可以采用全位图(Full bitmap)的方式指示所述基站发送的同步信号块。由于所述第二指示信息采用全位图的方式指示所述基站发送的同步信号块,因而指示的更加准确,减少因基站通过系统信息指示的同步信号块的信息不准确,导致终端可能对一些无法检测到的同步信号块也尝试进行搜索和检测,造成没有必要的耗电,或者,导致终端可能对一些实际发送的同步信号块没有搜索和检测,导致测量结果不准,或者无法保证终端正确解速率匹配和接收PDSCH/CORESET等问题。
本公开实施例中,基站会给终端配置三种CORESET(RMSI CORESET、UE-specific CORESET和其他CORESET)的配置信息,配置信息中包括对应CORESET的时频域等信息,从而终端能够根据该配置信息确定三种CORESET之间的复用关系,确定RMSI CORESET、UE-specific CORESET和其他CORESET的复用信息。
