示例性地,第一SI-RNTI和第二SI-RNTI是不同的,UE接收到对应SIB之后,若通过第一SI-RNTI解扰成功,则认为当前接收到的SIB-X携带有所述可用性指示;若通过第二SI-RNTI解扰成功,则可认为当前接收到的SIB-X未携带有所述可用性指示。
在另一些实施例中,所述SIB-X是由第三SI-RNTI加扰的调度物理下行共享信道PDSCH的SIB,携带所述可用性指示;由第四SI-RNTI加扰的调度PDSCH的SIB-Z不携带所述可用性指示;所述Z为不等于所述X的正整数。
例如,SIB-X可为新提出的SIB,该新提出的SIB可用于携带所述可用性指示。SIB-Z可包括相关技术中提到的不同于SIB-X的SIB-Z。SIB-Z和SIB-X用不同的SI-RNTI加扰。
示例性地,;所述第四SI-RNTI和所述第三SI-RNTI不同。
总之,SIB-X和SIB-X以外的SIB-Z用不同的SI-RNTI加扰,方便UE接收到之后根据加扰成功的序列,快速判断出那个SIB是否有携带可用性指示。
所述可用性指示可以由指示比特显性携带,也可以用于被隐性指示。
例如,在SIB-Y中携带有一个或多个指示比特,这些指示比特专门携带所述可用性指示。
又例如,通过SIB-Y中某一个信息是否有携带与可用性指示之间的对应关系,来隐性指示所述可用性指示。
因此在一些实施例中,所述SIB-1通过是否包含所述SIB-X的调度信息,来隐性指示所述可用性指示;
所述SIB-X通过是否包含所述预设参考信号的配置,隐性指示所述可用性指示。若所述预设参考信号的配置放在SIB-1中,则可以通过SIB-1中是否包含所述预设参考信号的配置,隐性指示所述可用性指示。
UE接收到该隐性指示可用性指示的SIB-Y之后,就可以根据上述任意对应关系,确定当前该预设参考信号的配置的可用性指示。
在一些实施例中,所述SIB-Y包含的SIB-X还用于携带所述预设参考信号的配置,其中,所述X为大于或等于2的正整数。
不同套的预设参考信号的配置,传输预设参考信号的至少部分时频资源不同。
例如,针对不同类型UE的预设参考信号的配置,则使用的时频资源至少部分不同,因此则可以认为是两套预设参考信号的配置。
在一些实施例中,所述***消息或者***消息的调度消息携带的所述可用性指示变更时,不触发***消息更新流程。示例性地,所述SIB-Y携带的所述可用性指示变更时,不触发***消息更新流程。示例性地,所述SIB-Y携带的所述可用性指示变更时,不触发SIB-Y的指示标签更新。
即UE接收到携带有可用性指示变更时,不会触发UE发起***消息更新流程,从而发起获取更新后的***消息的消息请求。
总之,***消息可以通过指示比特显性携带所述可用性指示;或者,通过隐性指示的方式携带所述可用性指示。
该可用性指示可为前述的可用性状态的指示和/或可用性变更的指示。
示例性地,所述***消息或者***消息的调度消息携带的所述可用性指示变更时,不触发***消息更新流程。示例性地,所述SIB-Y携带的所述可用性指示的指示标签变更时,不触发***消息更新流程。
在一个实施例中,所述寻呼消息变更通知,用于携带指示所述预设参考信号的可用性变更的第二类指示。
寻呼消息变更通知可为物理层信令,物理层信令的比特比较少,可以尽可能减少携带可用性变更,就可以在以尽可能少的比特来实现可用性指示。
在一个实施例中,所述寻呼消息变更通知,携带有比特位图;所述比特位图包括一个或多个比特;其中,一个所述比特用于指示所述预设参考信号的一套配置的可用性变更。
在一个实施例中,所述寻呼消息变更通知,携带所述预设参考信号的配置的可用性变更的可用性指示;其中,所述预设参考信号的多套配置的变更后的可用性指示由所述***消息或所述***消息的调度消息携带。
此处,通过寻呼消息变更通知,携带的多套预设参考信号的配置的总体可用性变更;相当于告知UE至少有一套预设参考信号的配置的可用性有变更,变更后的各套预设参考信号的配置的可用性,可以由***消息或者***消息调度消息来携带。
在一些实施例中,所述寻呼下行控制信息可为任意在基站调度的下发寻呼DCI的资源上传输的消息。示例性地,根据是否携带有可用性指示,所述寻呼下行控制信息可以包括两类:第一类寻呼下行控制信息为不携带可用性指示的paging DCI,第二类寻呼下行控制信息为携带有可用性指示的paging DCI。
有鉴于此,携带有所述可用性指示的所述寻呼下行控制信息为第二类寻呼下行控制信息,其中,所述第二类寻呼下行控制信息不同于不携带所述可用性指示的第一类寻呼下行控制信息。
第一类寻呼下行控制信息,可为相关技术中提供的paging DCI,该paging DCI携带有下发给UE的短消息和/或寻呼消息的调度消息的至少其中之一。
第二类寻呼下行控制信息,可以携带短消息和/或寻呼消息的调度消息的指示其中之一,也可以不携带短消息和/或寻呼消息的调度消息的至少其中之一,但是至少会携带预设参考信号的可用性指示和/或配置变更的至少其中之一。
在一些实施例中,所述第一类寻呼DCI和第二类寻呼DCI的格式可相同或者不同。例如,第二类寻呼DCI可以沿用相关技术中用于携带短消息和/或寻呼消息的调度消息的消息格式,也可以单独约定一种全新的消息格式。
在另一些实施例中,第二类寻呼DCI可以继续沿用第一类寻呼DCI的消息格式,但是可以对该消息格式内的各个比特携带的内容重新进行定义,则此时第二类寻呼DCI携带的预设参考信号的可用性指示和/或配置变更都可以携带在即便消息格式与第一类寻呼DCI相同的消息格式中的任意位置。
为了区分两类寻呼消息,第二类寻呼DCI和第一类寻呼DCI可以用不同的加扰序列进行加扰,如此,UE接收到之后通过解扰所用的序列不同,就可以区分出当前接收到的寻呼DCI是第一类寻呼DCI还是第二类寻呼DCI。
在一个实施例中,第二类寻呼下行控制信息,可为新增的一种寻呼下行控制信息,示例性地,第二类寻呼下行控制信息,为可以用于专用携带前述可用性指示。
在一个实施例中,所述第二类寻呼下行控制信息包括:指示域和消息域。在一些情况下,指示域通常用于指示消息域所携带的内容。指示域和消息域的至少其中之一都包含有一个或多个比特。示例性地,消息域包含的比特数多于指示域包含的比特数。
在一些情况下,第二类寻呼下行控制信息和第一类寻呼下行控制信息的消息格式相同,则第二类寻呼下行控制信息的指示域包含的比特数,与第一类寻呼下行控制信息包含的比特数相同;且第二类寻呼下行控制信息的消息域包含的比特数,与第一类寻呼下行控制信息包含的比特数相同。
为了实现与第一类下行寻呼控制信息的兼容,且实现第二类寻呼下行控制信息的可用性指示和/或预设参考信号的配置变更的携带。在本公开实施例中,响应于所述第二类寻呼下行控制信息与所述第一类寻呼下行控制信息的消息格式相同,所述可用性指示由所述指示域中未被所述第一类寻呼下行控制信息占用的比特值携带;或者,所述可用性指示由所述消息域中未被所述第一类寻呼下行控制信息占用的比特携带。
示例性地,所述指示域,可以用于指示消息域内携带的内容,具体可以参见如下实施例:
表1
表中的短消息指示域即为前述的指示域。
表为第二类寻呼DCI的指示域的具体举例,具体实现时可以不局限于上述举例。表1中指示域中携带“00”用于指示预设参考信号的可用性发生变更或者不发生变更。此时第二类寻呼DCI的指示域具有4中取值分别是“00”、“01”、“10”和“11”,其中,01”、“10”和“11”是被第一类寻呼DCI已经占用的,因此,若由指示域指示可用性指示,则可以由第一类寻呼下行控制信息未占用的比特值“00”来携带。
例如,若一个寻呼DCI的指示域的比特值为:“00”,可以用于指示可用性状态和/或可用性变更。
预留比特可为没有被占用的比特。
值得注意的是:表1中一个或多个元素可以组合应用于paging DCI或者单独应用于pagingDCI 中。
在一个实施例中,当然预设参考信号的可用性指示也可以携带在第二类寻呼DCI的消息域中。例如,可用性指示可以由第二类寻呼DCI的消息域中未被第一类寻呼DCI占用的比特或者比特值携带。
示例性地,第二类寻呼DCI和第一类寻呼DCI的格式相同,则消息域所包含的比特数也相同。在本公开实施例中,第二类寻呼DCI可以将消息域中的部分比特预留出来专门用于携带预设参考信号的相关信息,此处相关信息包含:前述的可用性指示和/或配置变更。
示例性地,消息域的比特安排可如下:
消息域(Message indicator) | |
00 | TRS/CSI-RS的可用性变更(availability change) |
01 | TRS/CSI-RS的配置变更(configuration change) |
10 | 保留(Reserved) |
11 | 保留(Reserved) |
表2
表2中显示的为从第二类寻呼DCI的消息域中取出两个比特来携带可用性变更和配置变更。
在一个实施例中,可用性变更和配置变更,可用占用两个比特的两个不同的比特值。
在另一个实施例中,第二类寻呼DCI的消息域中的去除的两个比特值,其中一个比特的用于携带可用性变更,另一个比特用于携带配置变更。如此,一个比特的两个比特值分别对应了可用性指示的可用性状态下的可用和不可用,或者,对应于可用性变更的变更和不变更。一个比特的两个比特值,可对应于配置变更的变更和不变更两种指示。
第二类寻呼DCI的消息域中取出来用于携带可用性变更和或配置变更的比特,可以是相对于第一类寻呼DCI而言是预留比特,也可以是已被第一类寻呼DCI占用用于携带短消息和/或寻呼消息的调度消息的比特。
在一个实施例中,所述第二类寻呼DCI和第一类寻呼DCI的格式相同,第二类寻呼DCI继续沿用第一类寻呼DCI的格式,同时引入了携带标记,该携带标记用于指示,第二类寻呼DCI至少携带了预设参考信号的可用性指示和/或配置变更。
示例性地,响应于所述第二类寻呼下行控制信息与所述第一类寻呼下行控制信息的消息格式相同,所述第二类寻呼下行控制信息的指示域在指示所述可用性指示的携带标记时的加扰序列不同,所述第二类寻呼下行控制信息的消息域携带有所述可用性指示。
在一个实施例中,携带标记对应于所述指示域中未被第一类寻呼DCI占用的比特值。若指示域带有的携带标记,则第二类寻呼DCI的消息域至少携带有前述可用性变更和/或配置变更的一种。
在另一个实施例中,响应于所述指示域不携带所述可用性指示的携带标记,所述配置变更由所述第二类寻呼下行控制信息的所述指示域内未被所述第一类寻呼下行控制信息占用的比特值指示;
或者,
响应于所述指示域指示所述可用性指示的携带标记,所述配置变更由所述第二类寻呼下行控制信息的所述消息域携带。
若第二类寻呼DCI和第一类寻呼DCI的消息格式不同,则第二类寻呼DCI仅是与第一类寻呼DCI可以在相同资源上传输的寻呼DCI,但是消息格式和携带的内容均有差异。若第二类寻呼DCI和第一类寻呼DCI的格式不同,则可用性指示和/或配置变更可以携带在第二类寻呼DCI内的任意位置处。
在一些实施例中,所述第二类寻呼下行控制信息的加扰序列,不同于所述第一类寻呼下行控制信息的加扰序列。
在一些实施例中,单独携带有所述配置变更的第二类寻呼下行控制信息的加扰序列,可不同于单独携带有所述可用性指示所述第二类寻呼下行控制信息的加扰序列。
此处的任意一类寻呼下行控制信息的加扰序列可为RNTI,示例性地,第一类寻呼下行控制信息和第二类寻呼下行控制信息的加扰序列可以相同或者不同。例如,所述第一类寻呼下行控制信息和第二类寻呼下行控制信息的加扰序列可为:寻呼无线网络临时标识(P-RNTI)。
第二类寻呼下行控制信息的加扰序列,不同于第一类寻呼消息控制信息,第一类寻呼下行控制信息的加扰序列为P-RNTI,而所述第二类寻呼下行控制信息的RNTI可为TRS-RNTI。
为了方便UE的解码,第一类寻呼下行控制信息和第二类寻呼下行控制信息的解扰所用的序列的不同,则可以简便确定出当前接收到寻呼DCI是否有携带可用性指示。
在一个实施例中,所述S110可包括:响应于所述预设参考信号的配置变更,通过所述预设消息发送所述预设参考信号的可用性指示。
如图3所示,本公开实施例提供一种信息处理方法,应用于用户设备UE中,包括:

在一个实施例中,所述预设消息包括:***消息;和/或,***消息的调度消息;和/或,
寻呼消息变更通知。
示例性地,所述寻呼消息变更通知包括:寻呼下行控制信息paging DCI;
和/或,寻呼提前指示PEI。
在一个实施例中,所述***消息包括以下至少之一:主消息块MIB;***消息块SIB-Y;其中,所述Y为正整数。
在一个实施例中,响应于所述预设消息为所述***消息的调度消息,所述可用性指示由携带在调度所述***消息的下行控制信息的预留比特携带。
示例性地,响应于所述预设消息为所述***消息的调度消息且所述***消息为SIB-Y,所述可用性指示由携带在包含所述SIB-Y的下行控制信息的预留比特携带。
在一个实施例中,所述SIB-Y为:SIB-1,其中,携带所述可用性指示的所述SIB-1的加扰序列,与不携带所述可用性指示的SIB的加扰序列不同;或者,携带所述可用性指示的SIB-1的加扰序列与SIB-Z1的加扰序列不同,所述Z1为不等于1的正整数;
或者,
SIB-X,其中,所述X为大于或等于2的正整数;携带所述可用性指示的所述SIB-X的加扰序列和不携带可用性指示的SIB-X的加扰序列不同;或者,携带所述可用性指示的SIB-X的加扰序列与SIB-Z2的加扰序列不同;所述Z2为不等于所述X的正整数SIB-1。
在一个实施例中,所述SIB-1通过是否包含所述SIB-X的调度信息,来指示所述可用性指示;或者,所述SIB-X通过是否包含所述预设参考信号的配置信息,来指示所述可用性指示;或者,所述SIB-X通过是否包含所述预设参考信号的配置,来指示所述可用性指示。
示例性地,所述SIB-1通过是否包含所述SIB-X的调度信息,隐性指示所述可用性指示;或者,所述SIB-X通过是否包含所述预设参考信号的配置信息,隐性指示所述可用性指示;或者,所述SIB-X通过是否包含所述预设参考信号的配置,隐性指示所述可用性指示。
在一个实施例中,所述SIB-Y还用于携带所述预设参考信号的配置。示例性地,SIB-X还用于携带所述预设参考信号的配置,其中,所述X为大于或等于2的正整数。
在一个实施例中,所述***消息或者***消息的调度消息携带的所述可用性指示变更时,不触发***消息更新流程。示例性地,所述SIB-Y携带的所述可用性指示变更时,不触发***消息更新流程。
在一个实施例中,所述寻呼消息变更通知,用于携带指示所述预设参考信号的可用性变更的第二类指示。
在一个实施例中,所述寻呼消息变更通知,携带有一个或多个指示标签;其中,一个所述指示标签用于指示所述预设参考信号的一套配置的可用性变更。
在一个实施例中,所述寻呼消息变更通知,携带所述预设参考信号的配置的可用性变更的所述可用性指示;其中,所述预设参考信号的多套配置的变更后的可用性指示由所述***消息或所述***消息的调度消息携带。
在一个实施例中,所述寻呼下行控制信息包括:携带有所述可用性指示的所述寻呼下行控制信 息为第二类寻呼下行控制信息,其中,所述第二类寻呼下行控制信息不同于不携带所述可用性指示的第一类寻呼下行控制信息。
在一个实施例中,所述第一类寻呼下行控制信息和所述第二类寻呼下行控制信息的消息格式县相同,例如,两类寻呼下行控制信息均包括:指示域;其中,所述指示域未被第一类寻呼下行控制信息占用的预留比特值,用于携带所述预设参考信号的可用性指示或预设参考信号的配置变更。
有鉴于此,在一些实施例中,响应于所述第二类寻呼下行控制信息与所述第一类寻呼下行控制信息的消息格式相同,所述可用性指示由所述指示域中未被所述第一类寻呼下行控制信息占用的比特值携带;或者,所述可用性指示由所述消息域中未被所述第一类寻呼下行控制信息占用的比特携带。
在一个实施例中,所述第一类寻呼下行控制信息和所述第二类寻呼下行控制信息的消息格式相同时,则这两类寻呼下行控制信息均包括:消息域。在第一类寻呼下行控制信息中,消息域原定用于寻呼消息的调度消息和/或短消息的携带。在本公开实施例中,第二类寻呼下行控制信息的消息域还可以用于携带预设参考信号的可用性指示和/或预设参考信号的配置变更。
在一个实施例中,响应于所述第二类寻呼下行控制信息与所述第一类寻呼下行控制信息的消息格式相同,所述第二类寻呼下行控制信息的指示域在指示所述可用性指示的携带标记时的加扰序列不同,所述第二类寻呼下行控制信息的消息域携带有所述可用性指示。
响应于所述第二类寻呼下行控制信息与所述第一类寻呼下行控制信息的消息格式相同,所述第二类寻呼下行控制信息还用于指示所述预设参考信号的配置变更。此处配置变更可以由任意未被第一类寻呼下行控制信息所占用的比特或者比特值携带。
示例性地,响应于所述指示域不携带所述可用性指示的携带标记,所述配置变更由所述第二类寻呼下行控制信息的所述指示域内未被所述第一类寻呼下行控制信息占用的比特值指示;或者,响应于所述指示域指示所述可用性指示的携带标记,所述配置变更由所述第二类寻呼下行控制信息的所述消息域携带。
在一个实施例中,所述S210可包括:
响应于预设参考信号的配置变更,接收携带有所述可用性指示的所述预设消息。
该预设消息可为各种网络侧下发的消息,例如,物理层信令、MAC CE和/或RRC信令等。在接收到更新后的配置变更之后,通过可用性指示的获取,可以知晓变更后的配置合适生效,确保UE是根据生效的配置监听TRS/CSI-RS等预设参考信号。
在一个实施例中,所述第二类寻呼下行控制信息的加扰序列,不同于所述第一类寻呼下行控制信息的加扰序列在一个实施例中,所述接收预设消息,包括以下至少之一:
响应于进行小区选择,接收携带有所述可用性指示的***消息或***消息的调度消息;
响应于进行小区重选,接收携带有所述可用性指示的***消息或***消息的调度消息;
响应于返回到服务区,接收携带有所述可用性指示的***消息或***消息的调度消息;
响应于接收到高层指示,接收携带有所述可用性指示的***消息或***消息的调度消息;
响应于所述预设参考信号的可用性指示失效,接收携带有所述可用性指示的***消息或***消息的调度消息;
响应于所述UE错过携带所述预设参考信号的可用性指示的寻呼下行控制信息或者PEI,接收携带有所述可用性指示的***消息或***消息的调度消息。
在执行小区选择、小区重选或返回到服务去,UE都有可能错过基站基于寻呼消息变更通知下发的预设参考信号的相关信息,此时的相关信息包括但不限于:前述预设参考信号的可用性指示和/或配置变更,此时,UE可以基于***消息的接收获取所述可用性指示和/或配置变更。
此处的高层指示,可包括:来自网络侧的非接入层(NAS)指示和/或接入层(AS)指示或者RRC指示,需要通过接收***消息或***消息的调度消息接收预设参考信号的可用性指示和/或配置变更。
同样地,在通信协议或者基于预先协商的结果发现,可用性指示失效或者发现网络侧有下发有针对预设参考信号的配置变更,则UE需要获取新的可用性指示,此时UE可以通过***消息获取或者***该消息的调度消息或者寻呼消息变更通知获取。
本公开实施例提供了一种传输TRS/CSI-RS的可用性指示的处理,主要涉及一种UE从***消息中获取对于TRS/CSI-RS的可用性指示的处理。
仅适用于空闲态/非激活态用户;
其中可用性指示包括TRS/CSI-RS可用(available)或者不可用(unavailable)信息;
其中可用性还指示包括TRS/CSI-RS可用性变更,由可用到不可用或者从不可用到可用;
其中可用状态:即该资源的配置是合理存在的,并且网络在实际发送该资源对应的特定参考信号;此时对于UE而言,即为可用的;网络期望UE使用;
其中不可用状态:即该资源的配置是不合理存在的,或者资源的配置是合理存在但是网络没有在实际发送该资源对应的特定参考信号;此时对于UE而言,即为不可用的;网络不期望UE使用
在一个实施例中,网络发送对于TRS/CSI-RS的可用性指示的可以通过如下途径:
显示方式:
携带在MIB中;
携带在SIB-1中;
携带在调度SIB-1的PDCCH DCI的预留比特中;
携带在SIB-X中,其中SIB-X携带了TRS/CSI-RS的配置信息;
携带在调度SIB-x的PDCCH DCI的预留比特中;
携带在一个新的SI-RNTI加扰调度的PDSCH(SIB)中;
可以理解地,TRS/CSI-RS的可用性指示,可以为一个指示或者为多个指示位,其中,每个指示位关联到一个TRS/CSI-RS资源的可用性。
TRS/CSI-RS的可用性指示可以为一个比特(bit)或者为一个比特位图(bitmap)。每个bit关联到一个TRS/CSI-RS资源的可用性指示。若可用性指示仅仅只需要指示可用或者不可用或者,指示 变更或者不变更,即on/off这两种表达,则可以用比特位图形式。作为一种实施例:TRS/CSI-RS的可用性指示可以命名为TRS/CSI-RS availability value tag。
可以理解地,指示标签(value tag)为取值范围为0~N。
作为一种实施例,N=1;即仅通过on/off翻转,
作为一种实施例,N=31;,即复用了相关技术中***消息的指示标签(value tag)。
可以理解地,对于TRS/CSI-RS的可用性指示携带在***消息中,其变更将不会触发***消息更新流程。
作为一种实施例,对于TRS/CSI-RS的可用性指示携带在SIB-X中,其变更将不会触发***消息更新流程。
作为一种实施例,对于TRS/CSI-RS的可用性指示携带在SIB-1中,其变更将不会触发***消息更新流程。
由隐式方式携带可用性指示,在在SIB-1中是否有携带SIB-X的调度信息,与预设参考信号的可用性指示具有对应关系;或者,在SIB-x是否有携带TRS/CSI-RS的配置信息,与预设参考信号的可用性指示具有对应关系。
在一个实施例中,UE需要在如下情况的至少之一时,从***消息中获取对于TRS/CSI-RS的可用性指示:
开机后进行小区选择(cell selection);例如,UE断电后之后重新上电。
小区重选(cell-reselection)后进入新的小区。
返回服务区,即从覆盖区域外(out of coverage)返回(return from out of coverage)返回到覆盖区域。覆盖区域就是服务区;覆盖范围外即为非服务区。
从其他无线接入技术(Radio Acces Thechnolgy,RAT)重选进入该小区l;例如,从异***个切入到本***的小区(after entering the network from another RAT)。示例性地,UE从4G小区切换到5G小区。
高层指示,(upon receiving request from upper layers),该高层指示可包括接入层(AS)指示、非接入层(NAS)指示或者RRC指示。
之前获取到的TRS/CSI-RS的可用性指示失效,例如,可以根据通信协议或者协商约定可用性指示的有效时长,若一个可用性指示生效的时长已经达到所述有效时长,则该可用性指示失效。
对于利用Paging DCI/PEI发送TRS/CSI-RS的可用性指示的场景,若DRX周期大于TRS/CSI-RS更新周期的UE,此时错过了Paging DCI/PEI发送TRS/CSI-RS的可用性指示;在PO监听之前获取该TRS/CSI-RS的可用性指示,然后根据该可用性指示进行PO的监听。
在一个实施例中,UE同时还需要在如下情况下从相关技术中的***消息更新流程或者Paging DCI/PEI发送TRS/CSI-RS可用性中获取对于TRS/CSI-RS的可用性指示。
网络将在TRS/CSI-RS的可用性变更的情况下,从相关技术中的***消息更新流程或者通过Paging DCI/PEI发送TRS/CSI-RS可用性指示变更。相关技术的***消息更新流程即网络仅仅通知 ***消息有变更,至于具体的***消息的变更,需要UE从***消息中获取。对于Paging DCI/PEI发送TRS/CSI-RS可用性见如下举例:
情况1:Paging DCI/PEI中可以直接携带TRS/CSI-RS可用性指示,一种实施例即比特/比特位图。
情况2:Paging DCI/PEI中可以直接携带TRS/CSI-RS可用性指示发生变更的一个总的indication,而具体的TRS/CSI-RS可用性指示需要通过2)从***消息中获取。
作为一种实施例,利用短消息(short message)中预留比特携带TRS/CSI-RS的可用性指示,比如TRS/CSI-RS的可用性变更(availability change flag)。此处的可用性变更的标志即为前述可用性变更的一种。
作为一种实施例,在短消息(short message)中预留比特用作比如TRS/CSI-RS的可用性变更。
表3
值得注意的是:表3中一个或多个元素可以组合应用于paging DCI或者单独应用于pagingDCI中。
作为一种实施例,引入一个新的RNTI加扰的paging DCI,用于指示TRS/CSI-RS可用性/配置变更;比如TRS-RNTI,可对老(legacy)UE不可见,因此不会唤醒老UE。示例性地,携带所述可用性指示的paging DCI可以用TRS-RNTI加扰循环冗余码校验(Cyclic Redundancy Check,CRC)。该paging DCI的格式可为格式1-0。该paging DCI可具有N个比特。
此处的短消息指示相当于前述的消息域。
该paging DCI可以具有以下几种格式:
格式1:
消息指示域(Messages Indicator)中的1个比特,用于可用性指示,该比特的取值为“0”和“1”,可分别为不可用/可用;其余N-1个比特用作后续预留使用。
paging DCI内多个保留比特,可以用于指示预设参考信号的一套配置是否可用。
格式2:
消息指示域(Messages Indicator)–用两个比特分别指示:预设参考信号的可用性变更和/或配置变更。其余N-2个比特用作后续预留使用。
表4
值得注意的是:表4中一个或多个元素可以组合应用于paging DCI或者单独应用于pagingDCI中。
网络将在TRS/CSI-RS配置变更的情况下,通过相关的***消息更新流程或者Paging DCI/PEI发送TRS/CSI-RS配置变更;
对于Paging DCI/PEI发送TRS/CSI-RS配置变更,作为一种实施例,在短消息(short message)中新增加一个比特(bit),比如TRS/CSI-RS的配置变更(configuration change flag);
作为一种实施例,在短消息(short message)中预留比特用作比如TRS/CSI-RS的配置变更(configuration change flag;)。
此处的比特域的比特值“00”和“01”分别对应于前述实施例中第二类寻呼下行控制信息的消息域中的第一比特值和第二比特值。
在一个实施例中,寻呼DCI的配置还可如下,即寻呼DCI可以携带预设参考信号的配置变更。
表5
值得注意的是:表5中一个或多个元素可以组合应用于paging DCI或者单独应用于paging DCI中。
