在NR系统中,无线资源控制(Radio Resource Control,RRC)连接状态的单播是存在混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈的。而其他系统的组播广播并没有引入反馈机制,也就是终端设备接收组播或者广播的业务是不需要反馈的,丢失也是没有补救措施的。此外,在NR系统中,针对单播业务定义了不同的下行控制信息(Downlink Control Information,DCI)格式,例如,对于下行调度,可以采用DCI格式1-0或DCI格式1-1;对于上行调度,可以采用DCI格式0-0或DCI格式0-1。其中DCI格式1-0还用于调度一些公共信息,如系统信息块(System Information Block,SIB)信息等,此时终端被配置系统信息无线网络临时标识符(System Information Radio Network Temporary Identity,SI-RNTI),根据该SI-RNTI去检测DCI格式1-0。
在NR中的一些业务,例如V2X、工业互联网等场景下的业务,对于组播广播传输的可靠性要求越来越高,所以针对组播广播引入反馈机制以确保业务传输的可靠性,用于保证组内所有成员都接收到了业务数据。因此,为了提高业务传输的可靠性,需要引入针对组播广播业务的上行反馈机制,使得网络可以根据反馈信息确定是否需要发起重传。
多媒体广播多播服务(Multimedia Broadcast Multicast Service,MBMS)是一种通过共享网络资源从一个数据源向多个终端设备传输数据的技术,在提供多媒体业务的同时能有效地利用网络资源,实 现较高速率(256kbps)的多媒体业务广播和组播。此外,MBMS业务的接收适用于RRC连接态(RRC_CONNECTED)或者RRC空闲态(RRC_IDLE)或者RRC去激活态(RRC_INACTIVE)状态的终端设备。
为了提升MBMS业务的可靠性,需要引入针对MBMS业务的反馈机制,而如何调度MBMS业务,即调度MBMS业务的DCI如何设计,以支持MBMS业务的反馈机制是需要解决的问题。
基于上述问题,本申请提出了一种基于DCI进行上行反馈的方案,对于通过组播或广播方式发送的业务,终端设备能够根据DCI进行上行反馈,以提升组播或者广播传输的可靠性。
以下通过具体实施例详述本申请的技术方案。
图2是根据本申请实施例的无线通信方法200的示意性流程图,如图2所示,该方法200可以包括如下内容中的至少部分内容:
S210,网络设备向终端设备发送第一DCI,该第一DCI用于调度承载第一类型业务的PDSCH;
S220,该终端设备接收该第一DCI;
S230,该终端设备根据该第一DCI进行针对该第一类型业务的上行反馈,其中,该第一类型业务是通过组播或广播的方式发送的。
可选地,该第一类型业务是MBMS业务。当然,该第一类型业务也可以是以组播或广播方式发送的其他业务,本申请对此并不限定。
在本申请实施例中,该终端设备接收该网络设备发送的物理下行控制信道(Physical Downlink Control Channel,PDCCH),该PDCCH包括该第一DCI。该终端设备在该第一DCI调度的PDSCH资源上接收该网络设备发送的承载第一类型业务的PDSCH,该终端设备根据该第一DCI进行针对该第一类型业务的上行反馈。
可选地,作为示例1,该终端设备根据该第一DCI,确定针对该第一类型业务的上行反馈的反馈方式。也就是说,该第一DCI具体用于该终端设备确定针对该第一类型业务的上行反馈的反馈方式。
在示例1中,具体地,该终端设备根据该第一DCI中包括的第一指示信息,确定针对该第一类型业务的上行反馈的反馈方式。也即,该第一指示信息用于指示针对该第一类型业务的上行反馈的反馈方式。
在示例1中,针对该第一类型业务的上行反馈可以是混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈。对于HARQ反馈,例如,若终端设备成功接收第一类型业务,终端设备反馈肯定应答(Acknowledgement,ACK),或者,终端设备什么也不反馈;又例如,若终端设备接收第一类型业务失败,终端设备反馈否定应答(Negative Acknowledgement,NACK)。当然,在本申请实施例中,针对该第一类型业务的上行反馈也可以是其他反馈,本申请对此并不限定。
可选地,在示例1中,该反馈方式包括以下中的一种:
仅反馈NACK;
反馈ACK或者NACK。
需要说明的是,不同的上行反馈方式具有不同的优点和不同的应用场景,例如,对于广播业务,所有的终端(包括RRC连接状态的终端、RRC去激活状态的终端和RRC空闲状态的终端)都需要接收数据,并且基站可能并不知道系统中有多少终端在接收,因此,基站可以配置终端只反馈NACK,网络检测是否接收到NACK即可判断是否有终端没有正确接收数据,进一步的,可以判断是否需要进行数据重传。对于组播业务,其接收端终端的个数通常是固定的,基站可以配置终端反馈ACK或NACK,并且每个终端使用独立的传输资源,因此基站检测所有终端发送的物理上行控制信道(Physical Uplink Control Channel,PUCCH)中承载的反馈信息,判断哪些终端已经正确接收,哪些终端没有,进一步的,可以决定是否进行数据重传,以及以单播方式为没有正确接收的终端重传,还是采用组播的方式为所有的组内终端重传。
可选地,作为示例2,该终端设备根据该第一DCI,确定PUCCH传输资源集合,该PUCCH传输资源集合中的目标PUCCH传输资源用于传输承载该第一类型业务的上行反馈信息的PUCCH。也就是说,该第一DCI具体用于该终端设备确定该PUCCH传输资源集合。
可选地,该上行反馈信息用于指示该第一类型业务是否被正确接收。
在示例2中,具体地,该终端设备根据该第一DCI中包括的第二指示信息,确定该PUCCH传输资源集合。也即,该第二指示信息用于指示该PUCCH传输资源集合。
进一步的,该终端设备根据第一信息从该PUCCH传输资源集合中确定该目标PUCCH传输资源;
其中,该第一信息包括以下中的至少一种:
参考信号接收功率(Reference Signal Received Power,RSRP)测量结果、该终端设备的无线网络临时标识符(Radio Network Temporary Identity,RNTI)、该终端设备所在通信组内的组内标识。
可选地,在本申请实施例中,该终端设备的RNTI包括以下中的至少一种:
小区RNTI(Cell-RNTI,C-RNTI),组播RNTI(Group-RNTI,G-RNTI),广播RNTI(Broadcast-RNTI,B-RNTI)。
在示例2中,例如,该终端设备根据RSRP测量结果,从该PUCCH传输资源集合中确定该目标PUCCH传输资源。假设该PUCCH传输资源集合包括3个PUCCH传输资源,其中,PUCCH传输资源#0对应RSRP范围0,PUCCH传输资源#1对应RSRP范围1,PUCCH传输资源#2对应RSRP范围2,此种情况下,假设终端设备所测量的RSRP测量结果属于RSRP范围1,则该目标PUCCH传输资源为PUCCH传输资源#1。
例如,如图3所示,网络设备配置3个RSRP门限,分别记为RSRP-THD1、RSRP-THD2、RSRP-THD3,并且配置了4个PUCCH传输资源,分别记为PUCCH传输资源#0、PUCCH传输资源#1、PUCCH传输资源#2、PUCCH传输资源#3,不同的RSRP范围对应不同的PUCCH资源,多个PUCCH传输资源之间可以是频分多路复用(Frequency-division multiplexing,FDM)、时分复用(time-division multiplexing,TDM)或码分复用(code division multiplexing,CDM)的,终端设备接收网络设备发送的MBMS数据,并且根据下行信号(例如同步信号块/物理广播信道块(synchronization signal/physical broadcast channel block,SS/PBCH),信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)等)测量下行RSRP,根据当前测量的RSRP判断所属的RSRP范围以及对应的PUCCH传输资源,进一步的,终端根据MBMS数据接收状态以及确定的反馈方式决定在该PUCCH传输资源上发送的信息。如果是只反馈NACK的反馈方式,如果终端没有正确接收MBMS数据,则在该对应的PUCCH传输资源上发送NACK,否则不发送反馈信息;如果是反馈ACK或者NACK,如果终端没有正确接收MBMS数据,则在该对应的PUCCH传输资源上发送NACK,如果终端正确接收MBMS数据,则在该对应的PUCCH传输资源上发送ACK。在一实施方式中,网络设备配置RSRP范围和PUCCH资源之间的对应关系。
在示例2中,例如,该终端设备根据该终端设备的RNTI,从该PUCCH传输资源集合中确定该目标PUCCH传输资源。例如,R PUCCH=mod(UE_RNTI,M),其中,UE_RNTI表示终端设备的RNTI,M表示PUCCH传输资源集合中的PUCCH传输资源个数,R PUCCH表示确定的目标PUCCH传输资源的索引,mod()表示取模运算。
需要说明的是,对于组播通信,通常为每个终端配置一个独立的组内标识(group member identity),即终端设备所在通信组内的组内标识,当网络设备为终端设备配置PUCCH传输资源集时,终端设备可以根据其在通信组内的组内标识从该PUCCH传输资源集中确定相应的PUCCH传输资源,从而使得每个组内终端都可以有独立的PUCCH传输资源。
例如,一个通信组包括4个终端设备,网络设备为其分配的组内标识(ID)分别为UE ID#0、UE ID#1、UE ID#2、UE ID#3,网络设备配置的PUCCH传输资源集包括8个PUCCH传输资源,当网络设备发送组播PDSCH时,各个终端设备根据各自组内标识(ID)在PUCCH传输资源集中确定对应的PUCCH传输资源。例如,R PUCCH=mod(UE_ID,M),其中M表示PUCCH传输资源集合中的PUCCH传输资源个数,R PUCCH表示确定的目标PUCCH传输资源的索引,mod()表示取模运算。如图4所示,UE ID#0对应PUCCH传输资源#0,UE ID#1对应PUCCH传输资源#1,UE ID#2对应PUCCH传输资源#2,UE ID#3对应PUCCH传输资源#3。
可选地,作为示例3,该终端设备根据第一信息从多个PUCCH传输资源集合中确定第一PUCCH传输资源集合,以及根据该第一DCI中包括的指示信息从该第一PUCCH传输资源集合中确定目标PUCCH传输资源,该目标PUCCH传输资源用于传输承载该第一类型业务的上行反馈信息的PUCCH。
可选地,在示例3中,该第一信息包括以下中的至少一种:
RSRP测量结果、该终端设备的RNTI、该终端设备所在通信组内的组内标识。
在示例3中,例如,该终端设备根据RSRP测量结果,从该多个PUCCH传输资源集合中确定该第一PUCCH传输资源集合。假设该多个PUCCH传输资源集合包括3个PUCCH传输资源集合,其中,PUCCH传输资源集合#0对应RSRP范围0,PUCCH传输资源集合#1对应RSRP范围1,PUCCH传输资源集合#2对应RSRP范围2,此种情况下,假设终端设备所测量的RSRP测量结果属于RSRP范围1,则该第一PUCCH传输资源集合为PUCCH传输资源集合#1。
在示例3中,例如,该终端设备根据该终端设备的RNTI,从该多个PUCCH传输资源集合中确定该第一PUCCH传输资源集合。例如,R PUCCHset=mod(UE_RNTI,Q),其中,UE_RNTI表示终端设备的RNTI,Q表示网络设备配置的PUCCH传输资源集合的个数,R PUCCHset表示确定的第一PUCCH传输资源集合的索引,mod()表示取模运算。
在示例3中,例如,该终端设备根据该终端设备所在通信组内的组内标识,从该多个PUCCH传 输资源集合中确定该第一PUCCH传输资源集合。例如,R PUCCHset=mod(UE_ID,Q),其中,UE_ID表示终端设备所在通信组内的组内标识,Q表示网络设备配置的PUCCH传输资源集合的个数,R PUCCHset表示确定的第一PUCCH传输资源集合的索引,mod()表示取模运算。
可选地,作为示例4,该终端设备根据该第一DCI,确定PUCCH传输资源集合以及从该PUCCH传输资源集合中确定目标PUCCH传输资源,其中,该目标PUCCH传输资源用于传输承载该第一类型业务的上行反馈信息。也就是说,该第一DCI具体用于该终端设备确定PUCCH传输资源集合以及从该PUCCH传输资源集合中确定目标PUCCH传输资源。
在示例4中,具体地,该终端设备根据该第一DCI中包括的第三指示信息确定该PUCCH传输资源集合,以及根据该第一DCI中包括的第四指示信息从该PUCCH传输资源集合中确定该目标PUCCH传输资源。也即,该第三指示信息用于指示该PUCCH传输资源集合,以及该第四指示信息用于指示该PUCCH传输资源集合中的该目标PUCCH传输资源。
例如,如图5所示,假设网络设备配置了两个PUCCH传输资源集合,分别记为PUCCH传输资源集合0和PUCCH传输资源集合1,且PUCCH传输资源集合0包括8个PUCCH传输资源,PUCCH传输资源的索引为[0,7],PUCCH传输资源集合1包括4个PUCCH传输资源,PUCCH传输资源的索引为[0,3]。例如,在第一DCI中携带2个信息域,第一信息域(即第三指示信息)用于指示PUCCH传输资源集合的索引,第二信息域(即第四指示信息)用于指示PUCCH传输资源的索引。网络设备在发送承载MBMS业务的PDSCH时,在其相关联的第一DCI中,通过第一信息域指示PUCCH资源集合索引0,即确定使用第一个PUCCH传输资源集合,在第二信息域中指示PUCCH传输资源索引3,即确定在该PUCCH资源集合索引0中的第4个PUCCH传输资源。由于MBMS是发送给一组终端,因此,接收到该第一DCI的终端使用相同的PUCCH传输资源进行HARQ反馈。
可选地,作为示例5,该终端设备根据该第一DCI确定RSRP门限信息;以及该终端设备根据RSRP测量结果和该RSRP门限信息,确定是否进行针对该第一类型业务的上行反馈。也就是说,该第一DCI具体用于该终端设备确定RSRP门限信息。此外,该RSRP门限信息用于该终端设备结合RSRP测量结果确定是否进行针对该第一类型业务的上行反馈。
需要说明的是,如果网络设备配置了RSRP门限以支持终端根据RSRP测量结果进行HARQ反馈,网络设备可以通过第一DCI指示某些终端进行反馈,而其他终端不需要进行反馈。
在示例5中的一些实施例中,具体地,该终端设备根据该第一DCI中包括的第一RSRP门限索引,从多个RSRP门限中确定第一RSRP门限。也即,该第一RSRP门限索引用于指示多个RSRP门限中的第一RSRP门限。
可选地,在示例5中,该终端设备根据该RSRP测量结果、该第一RSRP门限和第一约束条件,确定是否进行针对该第一类型业务的上行反馈。
可选地,该第一约束条件包括:当该RSRP测量结果低于该第一RSRP门限,进行针对该第一类型业务的上行反馈。具体地,当该RSRP测量结果低于该第一RSRP门限,该终端设备确定进行针对该第一类型业务的上行反馈,以及当该RSRP测量结果高于或者等于该第一RSRP门限,该终端设备确定忽略针对该第一类型业务的上行反馈。
例如,如图3所示,网络设备通过系统信息块(System Information Block,SIB)或无线资源控制(Radio Resource Control,RRC)信令配置3个RSRP门限,RSRP-THD1、RSRP-THD2、RSRP-THD3,这3个RSRP门限分别对应RSRP门限索引0、1、2;当网络设备在第一DCI中携带第一RSRP门限索引,并且该第一RSRP门限索引的取值为1,即可确定第一RSRP门限为RSRP-THD2,终端设备接收该第一DCI,并且如果该终端设备的RSRP测量结果低于RSRP-THD2,则该终端设备需要反馈HARQ,否则不反馈HARQ。
可选地,该第一约束条件包括:当该RSRP测量结果高于该第一RSRP门限,进行针对该第一类型业务的上行反馈。具体地,当该RSRP测量结果高于该第一RSRP门限,该终端设备确定进行针对该第一类型业务的上行反馈,以及当该RSRP测量结果低于或者等于该第一RSRP门限,该终端设备确定忽略针对该第一类型业务的上行反馈。
可选地,该第一约束条件包括:当该RSRP测量结果高于该第一RSRP门限时,反馈ACK或NACK,当该RSRP测量结果低于该第一RSRP门限时,只反馈NACK。
也就是说,对于RSRP测量结果高于第一RSRP门限的终端,其需要在第一类型业务接收失败的情况下反馈NACK,而在第一类型业务接收成功的情况下反馈ACK。而对于RSRP测量结果低于第一RSRP门限的终端,其需要在第一类型业务接收失败的情况下反馈NACK,而在第一类型业务接收成功的情况下忽略针对第一类型业务的上行反馈。
例如,网络设备通过SIB或RRC信令配置3个RSRP门限,RSRP-THD1、RSRP-THD2、 RSRP-THD3,这3个RSRP门限分别对应RSRP门限索引0、1、2;当网络设备在第一DCI中携带第一RSRP门限索引,并且该第一RSRP门限索引的取值为2,即可确定第一RSRP门限为RSRP-THD3。假设该终端设备的RSRP测量结果低于RSRP-THD3,则该终端设备需要在该第一类型业务接收失败的情况下反馈NACK,而在该第一类型业务接收成功的情况下忽略针对该第一类型业务的上行反馈。假设该终端设备的RSRP测量结果高于RSRP-THD3,则该终端设备需要在该第一类型业务接收失败的情况下反馈NACK,而在该第一类型业务接收成功的情况下反馈ACK。
可选地,该第一约束条件为预配置或者协议约定的,或者,该第一约束条件为网络设备配置的。
在示例5中的一些实施例中,具体地,该终端设备根据该第一DCI中包括的第一RSRP门限索引和第二RSRP门限索引,从多个RSRP门限中确定第一RSRP门限和第二RSRP门限。也即,该第一RSRP门限索引用于指示多个RSRP门限中的第一RSRP门限,以及该第二RSRP门限索引用于指示多个RSRP门限中的第二RSRP门限。
也就是说,网络设备可以配置多个RSRP门限,不同的RSRP门限对应不同的RSRP门限索引,网络设备在调度MBMS的DCI中携带指示信息,该指示信息包括RSRP门限索引,满足该门限索引的终端发送HARQ反馈,否则不发送。
具体地,当该RSRP测量结果在该第一RSRP门限与该第二RSRP门限之间的RSRP范围内,该终端设备确定进行针对该第一类型业务的上行反馈;或者,当该RSRP测量结果在该第一RSRP门限与该第二RSRP门限之间的RSRP范围外,该终端设备确定忽略针对该第一类型业务的上行反馈。
可选地,在示例5中,该多个RSRP门限为预配置或者协议约定的,或者,该多个RSRP门限为网络设备配置的。
例如,如图3所示,网络设备通过SIB或RRC信令配置3个RSRP门限,RSRP-THD1、RSRP-THD2、RSRP-THD3,这3个RSRP门限分别对应RSRP门限索引0、1、2;当网络设备在第一DCI中携带第一RSRP门限索引和第二RSRP门限索引,并且该第一RSRP门限索引的取值为1,即可确定第一RSRP门限为RSRP-THD2,该第二RSRP门限索引的取值为2,即可确定第一RSRP门限为RSRP-THD3,终端设备接收该第一DCI,并且如果该终端设备的RSRP测量结果位于RSRP-THD2和RSRP-THD3之间,则该终端设备需要反馈HARQ,否则不反馈HARQ。
在示例5中的一些实施例中,具体地,该终端设备根据该第一DCI中包括的第一RSRP门限范围索引,从RSRP门限范围列表中确定第一RSRP门限范围。也即,该第一RSRP门限范围索引用于指示RSRP门限范围列表中的第一RSRP门限范围。
具体地,当该RSRP测量结果在该第一RSRP门限范围内,该终端设备确定进行针对该第一类型业务的上行反馈;或者,当该RSRP测量结果在该第一RSRP门限范围外,该终端设备确定忽略针对该第一类型业务的上行反馈。
可选地,该RSRP门限范围列表为预配置或者协议约定的,或者,该RSRP门限范围列表为网络设备配置的。
例如,网络设备配置了2个RSRP门限,分别是RSRP-THD1、RSRP-THD2,其中RSRP-THD1>RSRP-THD2;并且网络设备配置了RSRP门限范围列表,如表1所示。网络设备在第一DCI中包括3比特,用于指示第一RSRP门限范围索引,终端根据该第一RSRP门限范围索引可以从表1中确定第一RSRP门限范围,当终端设备测量的RSRP在该第一RSRP门限范围内时,终端需要进行HARQ反馈,否则不需要。

需要说明的是,对于单播业务,网络设备为终端设备配置C-RNTI,网络设备与终端设备之间的数据传输通过C-RNTI加扰。当终端设备支持MBMS业务时,网络设备可以为终端设备配置G-RNTI或B-RNTI,并且第一DCI使用该G-RNTI或B-RNTI加扰,该第一DCI调度的MBMS数据也用相应的G-RNTI或B-RNTI加扰。
可选地,网络设备对不同的MBMS业务类型配置不同的G-RNTI或B-RNTI,如果终端设备对某种MBMS业务类型感兴趣,即需要接收的MBMS业务,网络设备为该终端配置该种MBMS业务所对应的G-RNTI或B-RNTI,使得终端设备可以接收该类型的MBMS业务,而不会接收其他类型的MBMS业务。
例如,系统中支持4中MBMS业务,对应MBMS#0、MBMS#1、MBMS#2和MBMS#3,网络配置4个G-RNTI分别对应这4种MBMS业务,即G-RNTI#0、G-RNTI#1、G-RNTI#2和G-RNTI#3,UE1向网络发送指示信息,通知网络其对MBMS#0和MBMS#1感兴趣,网络为UE1配置G-RNTI#0和G-RNTI#1。当网络设备发送不同类型的MBMS业务时,使用不同的G-RNTI加扰,由于UE1只配置了G-RNTI#0和G-RNTI#1,因此该终端设备只能检测MBMS#0和MBMS#1类型的业务,无法检测MBMS#2和MBMS#3的业务,避免该终端的无效检测。
因此,在本申请实施例中,对于通过组播或广播的方式发送的第一类型业务,终端设备能够根据用于调度承载第一类型业务的PDSCH的DCI,进行针对第一类型业务的上行反馈,以提升组播或者广播传输的可靠性。
进一步的,网络设备根据终端设备感兴趣的MBMS业务类型为其配置相应的G-RNTI或B-RNTI,使得终端设备可以接收相应的MBMS业务,避免接收不感兴趣的MBMS业务。
