图3为本公开的一些实施例的通信设备的结构框图;
图4为本公开的一些实施例的通信设备的模块示意图之一;以及
图5为本公开的一些实施例的通信设备的模块示意图之二。
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合具体实施例及附图进行详细描述。
本公开的一些实施例提供了一种资源指示方法,应用于发送端,如图1所示,包括:
步骤101:将接收端在单播和/或组播传输中所用的反馈资源指示给接收端,所述反馈资源至少包括接收端用的混合自动重传请求肯定ACK或否定NACK反馈资源。
上述反馈资源具体为反馈物理信道。上述反馈资源的配置由源UE(source UE)或基站来确定,具体来说,对于单播mode 1方式,由基站来确定,对于单播mode2方式,由source UE来确定;对于组播mode 1方式,可以由基站来确定,也可以由基站和簇配置共同决定;对于组播mode 2方式,由source UE和簇配置共同决定。
在本公开的一些实施例中,可将上述反馈资源动态指示给接收端, 如在调度控制信息SCI中指示具体的反馈资源;也可通过指示与反馈资源存在关联关系的业务资源来实现指示反馈资源。该业务资源包括PSSCH资源或PSCCH资源。
在本公开的一些实施例中,将接收端在单播和/或组播传输中所用的反馈资源指示给接收端,使得接收端能够在该反馈资源上反馈相应的信息,解决了目前关于终端间单播和组播传输的反馈资源的定义和指示还没有相关方案的问题。
进一步地,作为一种可选的实现方式,上述步骤101包括:
选择物理直通共享信道PSSCH资源和物理直通控制信道PSCCH资源,其中,选择的业务资源与反馈资源相关联,所述业务资源包括所述PSSCH资源或所述PSCCH资源;
将选择的PSSCH资源通过所述PSCCH资源的调度控制信息SCI指示给接收端。
在本公开的一些实施例中,业务资源与反馈资源的关联关系可以是***预配置或基站配置的。所述业务资源与反馈资源相关联包括:所述反馈资源在时域和/或频域上与业务资源相关联。
其中,所述反馈资源在时域上与业务资源相关联包括:
所述反馈资源在时域上与业务资源一一映射包括:每个所述反馈资源在时域上与所述业务资源间隔固定的N个时间单元,所述时间单元包括正交频分复用OFDM符号、传输时间间隔TTI或发送子帧,N为正整数。
这里,反馈资源在时域上与业务资源的映射关系为静态配置方式,可通过协议规定固定一个值,基本单位可以是秒,也可以是符号数或TTI个数。
或者,每个资源池关联一个反馈资源对应的时间间隔,所述资源池包括PSSCH资源和PSCCH资源。
这里,反馈资源在时域上与业务资源的映射关系为半静态配置方式,可以通过协议配置,对于每一种资源存在一种配置方式,比如通过***信息块SIB,无线资源控制RRC重配置或者预配置消息里对 每一个资源池关联一个反馈资源对应的反馈时间;这个配置关系对于每一个资源池是唯一的。基本单位同静态配置。资源池选择的时候,UE可以参考目标UE的处理能力和/或源UE业务的时延要求。目标UE处理能力是反馈时间的上限,目标UE反馈时间是连接建立过程中UE交互过的,比如目标UE处理能力比较低,不可能在1ms之后就完成译码并作出反馈,源UE可以选择较长的反馈时间;如果没有交互,则按照***规定的最低要求即最大处理时间来选择;同时需要考虑源UE业务的时要求,比如1ms,2ms。
或者,每个载波关联一个反馈资源与业务资源的固定的时间间隔。
或者,每个业务关联一个反馈资源与业务资源的固定的时间间隔,所述业务包含业务流QoS相关参数和/或每包每优先级PPPP。
另外,对于上述所提到的动态指示方式,业务资源与反馈资源不存在映射关系,具体的空隙gap值可以提前配置一些可能值,也可能不做任何限定;如果通过前一种方式的话,可以通过RRC消息来配置,比如1,2,4,5ms或者subframe等。在SCI中做动态的指示,这种指示就对应到相应的值。
其中,上述反馈资源在频域上与业务资源相关联包括:
所述反馈资源与业务资源的频域起始点以及频域大小完全相同。
或者,所述反馈资源的频域起始点为所述业务资源的第M个资源单元,且频域大小为固定的数值单元,M为正整数。
或者,所述反馈资源与载波和/或根资源池相关联。
其中,所述资源单元为资源粒子RE、物理资源块PRB或者子信道。
这里,反馈资源可以与PSSCH非完全同频域,但存在特定的映射关系,固定为一个或者多个值,比如固定起点位置和大小,比如确定为子带资源第一个或多个连续RE位置上,间隔为固定的,尤其是对于组播而言,反馈资源与PSSCH存在映射关系,即如果是完全同频域的话,反馈资源是跟PSSCH大小相关,但是其实反馈资源是跟组的成员个数相关的。
另外,对于上述所提到的动态指示方式,业务资源与反馈资源不存在映射关系,需要指示与业务资源的偏移offset关系,类似时域上的偏差,可以采用时域和频域offset联合编码的方式。
进一步地,本公开的一些实施例的资源指示方法,还包括:
指示与所述业务资源关联的反馈资源的位置信息和/或通过所述SCI中的第一目标字段消息指示选择的所述业务资源是否有关联的反馈资源。
所述目标字段消息包括:目标标识ID(destination ID)、目标组ID(destination group ID)、源节点ID、链路ID和预定字段消息中的至少一个。
在本公开的一些实施例中,对于静态配置方式,发送端可仅指示将选择的业务资源,并通过SCI中的第一目标字段消息指示选择的所述业务资源是否有关联的反馈资源。对于半静态配置方式,发送端除了指示选择的业务资源外,还需指示与所述业务资源关联的反馈资源的位置信息,该位置信息包括时域信息和频域信息。
例如,对于静态配置方式,SCI中增加一个比特用来指示是否存在反馈资源。接收节点根据这个指示判定是否有反馈资源。对于接收节点而言,要对反馈资源作对应的排除或者资源重传。如果判定自己是有效接收节点则需要反馈。
或者,对于静态配置方式,SCI中不作指示,节点通过其他方式指示是否有反馈资源;比如通过物理信息,比如destination ID/destination group ID作判定。物理层对于destination ID/destination group ID与传输方式(单播组播广播)存在一一映射的方式。
或者,对于静态配置方式,SCI中不作指示,节点通过其他方式或者是否有反馈资源;比如通过物理信息,比如高层的L2destination ID(服务service ID)来判定。高层对于服务ID与传输方式(单播组播广播)存在一一映射的方式。
或者,对于静态配置方式,SCI中增加一个比特用来指示调度方式,比如对于半持续调度SPS,只需要在最后一个发送资源接收后再 做反馈。或者直接规定是对SCI中所有资源作反馈还是只对最后一个资源作反馈。
进一步地,所述将接收端在单播和/或组播传输中所用的反馈资源指示给接收端之前,还包括:
在与接收端建立连接的过程中或者根据调度控制信息SCI中的第二目标字段消息,确定接收端反馈用的码字、序列和/或偏移值;
所述第二目标字段消息包括:目标终端标识ID、目标组ID、源节点ID、链路ID和偏移指示字段中的至少一个。
在本公开的一些实施例中,可以在与接收端建立连接的过程中,确定接收端反馈用的码字、序列和/或偏移值,也可以根据SCI中的第二目标字段消息,确定接收端反馈用的码字、序列和/或偏移值。
上述码字和/或序列可以有以下几种方式,连接通信连路的唯一标识,对于单播而言,一个会话session、或者source ID+destination ID;对于组播而言,可以采用destination group id等。
进一步地,所述将接收端在单播和/或组播传输中所用的反馈资源指示给接收端之后,还包括:
在所述反馈资源对应的位置对确定的码字和/或序列进行相关检测,获取接收端发送的反馈结果;
根据所述反馈结果,确定是否进行重传。
在本公开的一些实施例中,发送端在确定的资源上对确定的序列的检测,可以避免盲检测,且根据反馈结果,确定是否做重传。
进一步地,上述选择物理直通共享信道PSSCH资源和物理直通控制信道PSCCH资源,包括:
根据业务时延和接收端接收处理发送反馈的能力,确定所述接收端所用反馈资源对应的目标时间间隔;
根据资源池关联与反馈资源对应的时间间隔的关联关系,选择所述目标时间间隔所对应的目标资源池,并在所选择的目标资源池中选择业务资源。
本公开的一些实施例的资源指示方式,将接收端在单播和/或组 播传输中所用的反馈资源指示给接收端,使得接收端能够在该反馈资源上反馈相应的信息,解决了目前关于终端间单播和组播传输的反馈资源的定义和指示还没有相关方案的问题。
