可选的,上述副链路资源包括PSFCH(Physical Sidelink Feedback Channel,物理副链路反馈信道)资源和PSSCH(Physical Sidelink Shared Channel,物理副链路共享信道)资源中的至少之一。
其中,若副链路反馈信息为用于副链路的HARQ反馈信息,则副链路资 源包括发送HARQ反馈信息的PSFCH资源;若副链路反馈信息为用于副链路的CSI反馈信息,则副链路资源包括发送CSI反馈信息的PSFCH资源或PSSCH资源。当然,如果HARQ反馈信息在其他信道上发送,则副链路资源也不一定是PSFCH资源,而是其他信道上用于发送HARQ反馈信息的资源(如PSSCH上用于发送HARQ反馈信息的资源)。或者,如果PSFCH资源还用于发送其他信息,那么这里的副链路资源应当是PSFCH上用于发送HARQ反馈信息的资源。
本公开的一些实施例适用于第二终端需要发送副链路反馈信息,但第一终端却未获得第二终端用来发送副链路反馈信息的副链路资源的sidelink通信场景。
由于第二终端需要发送副链路反馈信息,因此,需要为第二终端配置或分配足够的副链路资源,以用来发送副链路反馈信息,否则,第二终端将无法实现副链路反馈信息的发送。而在某些情况下,网络侧设备或其他资源分配方没有配置或分配副链路资源或者没有配置或分配足够的副链路资源,或者,第一终端基于业务需求或其他原因,所选择的资源池不包括副链路资源。在上述这些情况下,均可视为第一终端未获得第二终端用来发送副链路反馈信息的副链路资源。在第一终端未获得第二终端用来发送副链路反馈信息的副链路资源时,第二终端将无法发送副链路反馈信息,这将导致sidelink传输性能较差的问题。
需要说明的是,第一终端未获得第二终端用来发送所述副链路反馈信息的副链路资源,既可以指第一终端完全没有获得用来发送所述副链路反馈信息的副链路时频域资源,也可以指第一终端没有获得足够的用来发送所述副链路反馈信息的副链路时频域资源。
本公开的一些实施例中,在面临上述问题时,第一终端可以通过多种方式实现副链路资源的获取,以下将一一进行具体说明。
方式一:第一终端向网络侧设备发送RRC连接建立请求或RRC连接恢复请求。
该方式中,上述第一终端处于RRC空闲态(即RRC_IDLE态)或RRC非激活态(即RRC_INACTIVE态),且不由其他终端分配资源。步骤301中 的通信设备即为上述网络侧设备。
可选的,在第一终端向网络侧设备发送RRC连接建立请求或RRC连接恢复请求之前,所述方法还包括:
第一终端接收网络侧设备发送的系统消息,所述系统消息包括用于副链路传输的配置信息。
方式二:第一终端向网络侧设备发送副链路资源请求。
该方式中,上述第一终端处于RRC连接态,且不由其他终端分配资源。步骤301中的通信设备即为上述网络侧设备。
可选的,在第一终端向网络侧设备发送副链路资源请求之前,所述方法还包括:
第一终端接收网络侧设备发送的系统消息或专用信令,所述系统消息或专用信令包括用于副链路传输的配置信息。
方式三:第一终端向第三终端发送副链路资源请求。
该方式中,上述第一终端由第三终端分配资源,步骤301中的通信设备即为上述第三终端。
需要说明的是,当第一终端工作在mode-2d模式下时,也可理解为第一终端由第三终端分配资源。此时,第一终端可能是mode-2d模式下的被调度终端,而第三终端可能是mode-2d模式下的调度终端。因此,在第一终端工作在该模式下时,第一终端可向第三终端发送副链路资源请求。
这里,上述mode-2d(或称Mode 2d)模式,即为终端自主选择资源模式mode 2下的一种子模式,该模式下存在调度终端和被调度终端,被调度终端的sidelink传输由调度终端进行调度。
可选的,在第一终端向第三终端发送副链路资源请求之前,所述方法还包括:
第一终端接收第三终端发送的专用信令,所述专用信令包括用于副链路传输的配置信息。
方式四:第一终端向网络侧设备发送RRC连接建立请求或RRC连接恢复请求,在第一终端RRC连接建立成功或RRC连接恢复成功的情况下,第一终端还向网络侧设备发送副链路资源请求。
通过上述方式,第一终端均有可能获取到副链路资源,第一终端可以将获取到的副链路资源通知给第二终端,这样,第二终端可使用该副链路资源来实现副链路反馈信息的发送,从而提高副链路传输性能。
本公开的一些实施例中,还提供一种用来确定第一终端是否获得上述副链路资源的方式。
即,当第一终端接收到通信设备发送的系统消息或专用信令,且系统消息或专用信令中包括用于副链路传输的配置信息时,所述第一终端未获得第二终端用来发送所述副链路反馈信息的副链路资源,包括:
所述配置信息中未包括副链路资源指示信息,所述副链路资源指示信息用于指示用来发送所述副链路反馈信息的副链路资源。
也就是说,当第一终端接收到通信设备发送的系统消息或专用信令,且系统消息或专用信令中包括用于副链路传输的配置信息时,若该配置信息中不包括副链路资源指示信息,则可确定第一终端未获得第二终端用来发送所述副链路反馈信息的副链路资源。
需要说明的是,配置信息中即便包括副链路资源指示信息,但该副链路资源指示信息所指示的副链路资源不包括足够的副链路时频域资源,也可视为该配置信息中不包括副链路资源指示信息。例如,第一终端与N个终端建立了单播连接,且与它们之间的单播业务都需要这N个终端发送副链路反馈信息。此时,即使配置信息中包括副链路资源指示信息,但是副链路资源指示信息所指示的副链路资源不足以这N个终端来发送副链路反馈信息,仍然确定第一终端未获得第二终端用来发送所述副链路反馈信息的副链路资源。
具体的,在以下条件中的至少之一满足时,可确定配置信息中未包括副链路资源指示信息:
配置信息中包含一个或多个用于第二终端进行sidelink发送和接收的资源池,其中全部或部分资源池中不包含副链路资源;
配置信息中包含一个或多个专门用于单播的资源池,其中全部或部分资源池中不包含副链路资源;
配置信息中包含一个或多个专门用于组播的资源池,其中全部或部分资源池中不包含副链路资源;
配置信息中包含一个或多个用于sidelink的发送资源池,其中全部或部分发送资源池中不包含副链路资源,或者,一个或多个用于第二终端发送单播业务的资源池中不包含副链路资源,或者,一个或多个用于第二终端发送组播业务的资源池中不包含副链路资源;
配置信息中包含一个或多个用于sidelink的接收资源池,其中全部或部分接收资源池中不包含副链路资源,或者,一个或多个用于第二终端接收单播业务的资源池中不包含副链路资源,或者,一个或多个用于第二终端接收组播业务的资源池中不包含副链路资源。
需要说明的是,发送资源池指的是终端会在上面发送业务数据,接收资源池指的是终端会在上面接收业务数据,并不表示发送资源池只能发送,接收资源池只能接收。终端会在发送资源池上接收发送的业务数据的副链路反馈信息。而终端也可能在发送资源池或接收资源池上发送针对对端业务的副链路反馈信息。
可选的,所述副链路资源指示信息包括以下至少之一:
副链路资源的时域(time)信息;
副链路资源的频域(frequency)信息;
副链路资源的编码(code)信息;
副链路资源的周期信息,例如,假设副链路资源每N个时隙(slot)重复配置一次,则N的取值即为副链路资源的周期信息,N为整数;
副链路资源与PSCCH(Physical Sidelink Control Channel,物理副链路控制信道)资源的关系信息,例如,假设副链路资源在PSCCH资源之后的A个slot配置,则A的取值即为副链路资源与PSCCH资源的关系信息,A为整数;
副链路资源与PSSCH资源的关系信息,例如,假设副链路资源在PSSCH资源之后的B个slot配置,则B的取值即为副链路资源与PSSCH资源的关系信息,B为整数;
用于确定副链路资源与PSSCH资源关系信息的参考信息,例如,假设副链路资源在PSSCH资源之后的C个slot配置,而C的值与K相关,则K的取值即为用于确定副链路资源与PSSCH资源关系信息的参考信息(如,C为 大于或等于K的最小整数),C和K均为整数。
可选的,所述第一终端向通信设备发送副链路资源请求,包括以下至少之一:
所述第一终端向所述通信设备发送第一副链路终端信息(SidelinkUEInformation),所述第一副链路终端信息中携带有所述副链路资源请求;
在所述第一终端需要向所述通信设备发送第二副链路终端信息时,所述第一终端在所述第二副链路终端信息中携带所述副链路资源请求;
所述第一终端向所述通信设备发送第一辅助信息,所述第一辅助信息中携带有所述副链路资源请求;
在所述第一终端需要向所述通信设备发送第二辅助信息时,所述第一终端在所述第二辅助信息中携带所述副链路资源请求;
所述第一终端向所述通信设备发送第一BSR(Buffer Status Report,缓存状态报告),所述第一BSR中携带有所述副链路资源请求;
在所述第一终端需要向所述通信设备发送第二BSR时,所述第一终端在所述第二BSR中携带所述副链路资源请求;
所述第一终端向所述通信设备发送RRC消息,所述RRC消息中携带有所述副链路资源请求。
本公开的一些实施例中,还提供多种用来确定第二终端是否需要向第一终端发送副链路反馈信息的方式。
即,在以下条件中的至少之一满足时,确定所述第二终端需要向所述第一终端发送所述副链路反馈信息:
所述第一终端激活了反馈功能;
配置信息中包含用于单播的资源信息,所述配置信息用于副链路传输;
配置信息中包含用于组播的资源信息,所述配置信息用于副链路传输;
所述第一终端与至少一个终端建立了单播连接或交换了与单播通信相关的信息,所述至少一个终端包括所述第二终端;

所述第一终端与至少一个终端之间存在需要反馈的单播业务,所述至少一个终端包括所述第二终端;
所述第一终端与至少一个终端之间存在需要反馈的组播业务,所述至少一个终端包括所述第二终端;
所述第一终端接收到第一指示信息,所述第一指示信息用于指示所述第一终端有单播业务到达,或者,用于指示所述第一终端存在需要反馈的单播业务;
所述第一终端接收到第二指示信息,所述第二指示信息用于指示所述第一终端有组播业务到达,或者,用于指示所述第一终端存在需要反馈的组播业务;
所述第一终端检测到至少一个终端位于需要发送副链路反馈信息的通信范围内或进入了需要发送副链路反馈信息的通信范围,所述至少一个终端包括所述第二终端。
需要说明的是,上述用于单播的资源信息可以包括资源池信息,或其他可以指示资源时频位置的信息。上述用于组播的资源信息可以包括资源池信息,或其他可以指示资源时频位置的信息。上述第一指示信息可以是第一终端上层指示给第一终端的,也可以是第一终端从外部接收到的。上述第二指示信息可以是第一终端上层指示给第一终端的,也可以是第一终端从外部接收到的。
还需要说明的是,可通过以下方式来确定第二终端是否位于需要发送副链路反馈信息的通信范围内:
方式一:基于第二终端接收到的从第一终端发来的数据包、控制信息或SFCI(Sidelink Feedback Control Information,副链路反馈控制信息)(包括HARQ反馈信息和CSI反馈信息)中携带的的位置信息,第二终端计算出与第一终端的距离,并与某个阈值进行比较。若低于该阈值,则可视为第二终端位于需要发送副链路反馈信息的通信范围内,否则,视为第二终端不位于需要发送副链路反馈信息的通信范围内。上述位置信息可能是地理坐标,或区域(zone)ID,或区域信息,或其他能反映或推测出地理位置的信息。
方式二:基于测量接收到的第一终端发来的参考信号,通过测量得到的 信号的RSRP(Reference Signal Received Power,参考信号接收功率)/RSRQ(Reference Signal Received Quality,参考信号接收质量)/SINR(Signal-to-noise and interference ratio,信号与干扰加噪声比)/RSSI(Received Signal Strength Indication,接收信号强度指示)等与一个阈值进行比较。若高于该阈值,则可视为第二终端位于需要发送副链路反馈信息的通信范围内,否则,视为第二终端不位于需要发送副链路反馈信息的通信范围内。
这里,上述通信范围指的是用于判断是否需要第二终端发送副链路反馈信息的范围,不代表发送数据、接收数据或控制信息的范围。
为了更清楚地理解本公开的一些实施例,以下从多个示例对本公开的一些实施例进行具体的说明。

其中,若副链路反馈信息为用于副链路的HARQ反馈信息,则副链路资源包括发送HARQ反馈信息的PSFCH资源;若副链路反馈信息为用于副链路的CSI反馈信息,则副链路资源包括发送CSI反馈信息的PSFCH资源或PSSCH资源。当然,如果HARQ反馈信息在其他信道上发送,则副链路资源也不一定是PSFCH资源,而是其他信道上用于发送HARQ反馈信息的资源(如PSSCH上用于发送HARQ反馈信息的资源)。或者,如果PSFCH资源还用于发送其他信息,那么这里的副链路资源应当是PSFCH上用于发送HARQ反馈信息的资源。
本公开的一些实施例适用于第二终端需要发送副链路反馈信息,但第二终端却未获得其用来发送副链路反馈信息的副链路资源的sidelink通信场景。
在上述sidelink通信场景下,第二终端可以通过多种方式实现副链路资源的获取,以下将一一进行具体说明。
方式一:第二终端向网络侧设备发送RRC连接建立请求或RRC连接恢复请求。
该方式中,上述第二终端处于RRC空闲态(即RRC_IDLE态)或RRC非激活态(即RRC_INACTIVE态),且不由其他终端分配资源。步骤401中的通信设备即为上述网络侧设备。
可选的,在第二终端向网络侧设备发送RRC连接建立请求或RRC连接恢复请求之前,所述方法还包括以下至少之一:

方式二:第二终端向网络侧设备发送副链路资源请求。
该方式中,上述第二终端处于RRC连接态,且不由其他终端分配资源。步骤401中的通信设备即为上述网络侧设备。

方式四:第二终端向第三终端发送副链路资源请求。
该方式中,上述第二终端由第三终端分配资源,步骤401中的通信设备即为上述第三终端。
需要说明的是,当第二终端工作在mode-2d模式下时,也可理解为第二终端由第三终端分配资源。因此,在第二终端工作在该模式下时,第二终端可向第三终端发送副链路资源请求。
可选的,在第二终端向第三终端发送副链路资源请求之前,所述方法还包括:
所述第二终端接收网络侧设备发送的系统消息,所述系统消息包括用于 副链路传输的第一配置信息;
第二终端接收第三终端发送的RRC消息,所述RRC消息包括用于副链路传输的配置信息。
方式五:第二终端向网络侧设备发送RRC连接建立请求或RRC连接恢复请求,在第二终端RRC连接建立成功或RRC连接恢复成功的情况下,第二终端还向网络侧设备发送副链路资源请求。
需要说明的是,上述方式一至方式五中,第一终端可理解为与第二终端进行sidelink通信的终端,第一终端可理解为进行sidelink通信的发送终端,即需要发送数据或者正在发送数据的终端,第二终端可理解为进行sidelink通信的接收终端,即需要接收数据或者正在接收数据的终端。由于数据的发送和接收可能是双向的,因此,上述发送终端是指某个时间区间发送数据的终端,接收终端是指同一时间区间接收数据,并需要对接收的数据进行反馈的终端。上述第一终端可以是单播通信中的业务发送终端或对端,也可能是组播通信中的组头终端,也可能是组播通信中的任一组员终端。

上述第三终端发送的RRC消息也可以包括PC5-RRC消息。
这里,上述PC5-RRC消息是指在sidelink上进行传输的RRC消息。
通过上述各方式,第二终端均有可能获取到副链路资源,这样,第二终端可使用该副链路资源来实现副链路反馈信息的发送,从而提高副链路传输性能。
本公开的一些实施例中,还提供多种用来确定第二终端是否获得上述副链路资源的方式。

需要说明的是,第一配置信息或第二配置信息中即便包括副链路资源指示信息,但该副链路资源指示信息所指示的副链路资源不包括足够的副链路时频域资源,也可视为上述任一配置信息(第一配置信息或第二配置信息)中不包括副链路资源指示信息。
具体的,在以下条件中的至少之一满足时,可确定上述任一配置信息中未包括副链路资源指示信息:

需要说明的是,发送资源池指的是终端会在上面发送业务数据,接收资源池指的是终端会在上面接收业务数据,并不表示发送资源池只能发送,接收资源池只能接收。终端会在发送资源池上接收发送的业务数据的副链路反馈信息。而终端也可能在发送资源池或接收资源池上发送针对对端业务的副 链路反馈信息。
可选的,所述副链路资源指示信息包括以下至少之一:

为了更清楚地理解本公开的一些实施例,以下从多个示例对本公开的一些实施例进行具体的说明。
示例一:接收端UE2为RRC_IDLE或RRC_INACTIVE态,且UE2用来发送HARQ反馈信息的资源由网络侧设备配置。其中,UE2为单播业务中的接收端,UE2的HARQ反馈信息既可以发给网络侧设备,也可以发给与UE2进行sidelink通信的发送端UE1。
