Description
本申请要求在2023年04月03日提交中国国家知识产权局、申请号为2023103484640的中国专利申请的优先权,发明名称为“资源排除方法及相关装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信领域,尤其涉及一种资源排除方法及相关装置。
目前第三代合作伙伴计划(third generation partnership project,3GPP)在版本(release)18中对侧行链路(sidelink,SL)传输进行了讨论,其主要提出了长期演进(long term evolution,LTE)与新空口(new radio,NR)车联网(vehicle-to-everything,V2X)共存的方案,具体涉及LTE/NR同信道共存(co-channel coexistence)场景,即LTE sidelink与NR sidelink可以共享资源,其中,对于该研究中支持的包含LTE模组和NR模组的终端设备,LTE模组可感知/发送LTE传输,NR模组可感知/发送NR传输。但是,由于NR模组无法感知LTE传输,这种LTE/NR同信道共存场景可能发生LTE sidelink与NR sidelink的传输冲突。
发明内容
本申请实施例提供一种资源排除方法及相关装置,可避免NRsidelink传输与LTE sidelink传输发生资源冲突,提高通信的可靠性。
第一方面,本申请实施例提供了一种资源排除方法,应用于终端设备,所述终端设备包括第一通信模组和第二通信模组,该方法包括:
所述终端设备的第一通信模组根据触发资源选择的时间单元,确定资源选择窗;
所述终端设备的第一通信模组在所述资源选择窗对应的候选资源集合中排除第一候选资源;其中,所述第一候选资源与第一预留资源有重叠,所述第一预留资源为用于传输所述第二通信模组支持的网络制式的控制信息的资源。
在本申请中,第一通信模组可以为NR模组,第二通信模组可以为LTE模组,第二通信模组支持的网络制式的控制信息可以为物理侧行链路共享信道(physical sidelink shared channel,PSSCH)上传输的侧行链路控制信息(sidelink control information,SCI)。应理解,通过从为NR传输进行的资源选择过程中确定的候选资源集合中排除LTE周期性传输对应的PSCCH使用的资源,可避免由于NR模组资源选择时将LTE周期性传输对应的PSCCH使用的资源作为候选资源,而造成LTE sidelink与NR sidelink传输使用相同资源,造成资源冲突问题,进而提高了通信的可靠性。
可选的,结合第一方面,所述第一预留资源为用于传输所述第二通信模组支持的网络制式的控制信息的资源,包括:
所述第一预留资源为用于传输第二预留资源对应的控制信息的资源,所述第二预留资源为第二通信模组感知到的传输所预留的资源;或者,
所述第一预留资源为为所述第二通信模组支持的网络制式配置的资源池中用于传输控制信息的资源。
在该种实现方式下,第一预留资源可以为用于传输PSCCH的资源,第二预留资源可以为用于传输PSSCH的资源,或者,第一预留资源可以为资源选择窗内所有可以用于传输第二通信模组支持的网络制式的数据对应的控制信息的资源。

可选的,结合第一方面,所述第一RSRP测量值为物理侧行链路共享信道PSSCH上的RSRP测量值。
在该种实现方式下,由于目前LTE sidelink仅支持对PSSCH上的解调参考信号(demodulation reference signal,DMRS)进行RSRP测量,而不支持对PSCCH上的DMRS进行RSRP测量,因此,可以直接将PSSCH上的RSRP测量值作为PSCCH上的RSRP测量值(即第一RSRP值),实现方式简单。
可选的,结合第一方面,所述第一RSRP测量值为对PSSCH上的RSRP测量值进行功率补偿后得到的RSRP测量值。
在该种实现方式下,第一RSRP测量值为第二通信模组支持的网络制式的PSSCH的RSRP测量值,考虑到实际PSCCH上的功率大于PSSCH上的功率(这是因为LTE sidelink对PSCCH的功率谱密度(power spectral density,PSD)提升(boosting)),如果直接使用PSSCH上RSRP测量值进行资源排除并且NR sidelink使用与该PSCCH重叠的候选资源传输,会导致NR sidelink和LTE sidelink都会收到较高的干扰,严重影响LTE sidelink和NR sidelink传输,因此,本申请实施例还可以对PSSCH上的RSRP测量值进行功率补偿后作为PSCCH上的RSRP测量值(即第一RSRP值),实现简单,且得到的第一RSRP值准确性更高。
可选的,结合第一方面,所述第一RSRP测量值满足:

可选的,结合第一方面,所述第一候选资源与所述第一预留资源有重叠,包括:
所述第一候选资源与所述第一预留资源有重叠,且所述第一预留资源上传输的控制信息所指示的优先级低于所述第一通信模组的待传输数据的优先级。
可选的,结合第一方面,所述资源选择窗对应的候选资源集合为以下集合中的任意一种:
初始化的候选资源集合;或者,
在所述初始化的候选资源集合中排除第三预留资源之后的候选资源集合,所述第三预留资源为在所述资源选择窗中确定的时间单元上的资源,所述在所述资源选择窗中确定的时间单元根据所述终端设备因半双工原因无法接收的时间单元确定;或者,
在所述初始化的候选资源集合中排除第三预留资源和被其他支持第一通信模组支持的网络制式的终端设备预留且第二RSRP测量值大于第二RSRP阈值的候选资源之后的候选资源集合,所述第三预留资源为在所述资源选择窗中确定的时间单元上的资源,所述在所述资源选择窗中确定的时间单元根据终端的资源感知窗内因半双工原因无法接收的时间单元确定。
在该种实现方式下,第二RSRP测量值为第一通信模组支持的网络制式的PSSCH或PSCCH上的RSRP测量值。

确定单元,用于根据触发资源选择的时间单元,确定资源选择窗;
排除单元,用于在所述资源选择窗对应的候选资源集合中排除第一候选资源;其中,所述第一候选资源与第一预留资源有重叠,所述第一预留资源为用于传输所述第二通信模组支持的网络制式的控制信息的资源。
可选的,结合第二方面,所述第一预留资源为用于传输所述第二通信模组支持的网络制式的控制信息的资源,包括:

在非相邻结构的资源池中,控制信道(例如物理侧行链路控制信道(physical sidelink control channel,PSCCH))和数据信道(例如物理侧行链路共享信道(physical sidelink shared channel,PSSCH))不相邻,所有的控制信道使用的资源位于资源池较低的频率范围,而所有数据信道使用的资源位于资源池较高频率范围部分,如图2中(a)所示。其中,控制信道与数据信道使用的资源间存在对应关系,如图2中(a),侧行链路控制信息(sidelink control information,SCI)1对应Data1,SCI2对应Data2,SCI3对应Data3。在另一种相邻结构的资源池中,如图2中(b)所示,控制信道和数据信道相邻,在进行资源分配时,PSCCH与PSSCH占用的资源共同被视为一个候选资源。
2、侧行链路(sidelink,SL)
SL是指针对终端设备和终端设备之间直接通信定义的。也即终端设备和终端设备之间不通过基站转发而直接通信的链路。
3、感知和资源选择
R16 NR V2X除了支持基于调度的资源分配模式(mode 1),还支持终端自主资源选择的资源分配模式(mode 2)。
mode 2是一种基于感知的资源选择机制,感知和资源选择过程的时域粒度为时隙(slot),频域粒度为子信道(sub-channel)。工作在mode 2的UE一直都在进行感知,当触发了资源选择过程时,UE物理层通过前面一段时间(资源感知窗)内的感知结果判断将来一段时间(资源选择窗)内的资源占用情况,排除资源选择窗内的不可用的资源,最后形成一个候选资源集合上报给媒体接入控制(media access control,MAC)层,MAC层根据
资源选择约束条件在该候选资源集合中选择传输资源。如图3所示,假设UE4在n时刻触发了资源选择过程,此时,会依据资源感知窗内感知到的传输,确定该传输在资源选择窗内的资源预留情况,进行排除。具体地,如图3所示,假设UE4感知到了UE1的传输,该传输进行了周期性预留,进一步地,需要比较感知到的UE1的RSRP与RSRP阈值大小关系,若UE1的RSRP大于RSRP阈值,则需要排除对应的候选资源,即排除被其他UE预留且RSRP测量值高于阈值的候选资源。类似地,UE4针对感知到的UE2和UE3的传输,该UE2和UE3的传输进行了重传预留,如图3中由于UE3的RSRP小于RSRP阈值,因此,不需要排除UE3对应的候选资源。
需要说明的是,目前3GPP R18中对SL传输进行了讨论,其主要提出了LTE与NR V2X共存的方案,具体涉及LTE/NR同信道共存(co-channel coexistence)场景,即LTE sidelink与NR sidelink共享部分资源,如图4为包含双模组的终端设备的示意图。其中,LTE模组可感知/发送LTE传输,NR模组可感知/发送NR传输。但是,这种LTE/NR同信道共存(co-channel coexistence)场景中,若NR sidelink模组无法获知LTE sidelink的传输资源或者预留资源,可能会选择部分重叠资源用于传输,进而造成资源冲突。
基于此,本申请实施例提供了一种资源排除方法,可避免资源冲突,提高通信的可靠性。
下面进一步对本申请实施例提供的资源排除方法、装置、芯片及芯片模组进行详细描述。
请参见图5,图5是本申请实施例提供的资源排除方法的一流程示意图。需要说明的是,本申请实施例可以适用于支持多模组,例如可以是双模组(如第一通信模组和第二通信模组)的终端设备,且该第一通信模组和第二通信模组可以共享资源。例如,该终端设备可以支持LTE与NR sidelink双模组,其中LTE sidelink在支持NR与LTE sidelink共存的载波上配置有PSCCH与PSSCH非相邻结构的资源池,且NR sidelink配置的资源池与该非相邻结构的资源池有重叠。如图5所示,该资源排除方法包括如下步骤S501~S502:
S501、终端设备的第一通信模组根据触发资源选择的时间单元,确定资源选择窗。
示例性地,上述终端设备的第一通信模组可以是NR模组,时间单元是第一终端设备和第二终端设备之间以时间单元为粒度进行通信,时间单元可以是时隙(slot)、子帧(subframe)、迷你时隙(Mini slot)等,在此不做限定。其中,根据触发资源选择的时间单元,n,资源选择窗确定为[n+T1,+T2]。其中,T1≤Tproc,1,可理解的,Tproc,1是一个资源选择和数据准备等的处理时间,在{15,30,60,120}kHz的子载波间隔(sub-carrier space,SCS)下分别配置为{3,5,9,17}个时隙。其中,T2min≤T2≤Remaining PDB,这里,PDB即剩余的包延迟预算(packet delay budget)的简称。可理解的,T2min由高层根据优先级在{1,5,10,20}*2^μ中配置,μ=0,1,2,3分别对应{15,30,60,120}kHz SCS。
S502、终端设备的第一通信模组在资源选择窗对应的候选资源集合中排除第一候选资源。
需要说明的是,本申请实施例中资源选择窗对应的候选资源集合中的候选资源用于传输第一通信模组的数据。示例性地,该候选资源集合可以为以下集合中的任意一种:
1、初始化的候选资源集合,即资源选择窗内所有候选资源组成的集合。
2、在初始化的候选资源集合中排除第三预留资源之后的候选资源集合,其中第三预留资源为在资源选择窗中确定的时间单元上的资源,在资源选择窗中确定的时间单元根据终端设备因半双工原因无法接收的时间单元确定。这里,初始化的候选资源集合,即资源选择窗内所有候选资源组成的集合。
3、在初始化的候选资源集合中排除第三预留资源和被其他支持第一通信模组支持的网络制式的终端设备预留且第二RSRP测量值大于第二RSRP阈值的候选资源之后的候选资源集合,第三预留资源为在资源选择窗中确定的时间单元上的资源,在资源选择窗中确定的时间单元根据终端的资源感知窗内因半双工原因无法接收的时间单元确定。这里,初始化的候选资源集合,即资源选择窗内所有候选资源组成的集合。应理解,第二RSRP测量值为第一通信模组支持的网络制式的PSSCH或PSCCH上的RSRP测量值。
可理解的,资源选择窗对应的候选资源集合中包括一个或者多个候选资源,其中,该资源选择窗对应的候选资源集合中被排除的候选资源为第一候选资源,被排除的候选资源(即第一候选资源)与第一预留资源有重叠,这里,第一候选资源与第一预留资源的部分重叠或全部重叠皆可以理解为第一候选资源与第一预留资源有重叠。可理解的,上述第一预留资源为用于传输第二通信模组支持的网络制式的控制信息的资源。示例性地,上述第二通信模组可以是LTE模组,其中LTE模组支持的网络制式可以理解为LTE制式,相应地,NR模组支持的网络制式可以理解为NR制式。可选的,第二通信模组支持的网络制式传输的控制信息可以是PSCCH(或称SCI)等。
需要说明的是,为了尽可能避免NR模组资源选择的传输资源与LTE传输冲突,可以由LTE模组向NR模组提供辅助信息,该辅助信息用于NR模组的资源选择。可理解的,现有辅助信息中包括的是LTE模组感知到的其他LTE UE预留的资源的信息,这里,其他LTE UE预留的资源为其他LTE UE用于PSSCH传输的资源。应理解,本申请实施例中涉及的第一预留资源可以是NR模组依据LTE模组发送的辅助信息中包含的其他LTE UE预留的资源的信息,所推断出的PSCCH所在时频域位置。可选的,LTE模组发送的辅助信息中直接包含PSCCH所在时频域位置,该PSCCH所在时频域位置即第一预留资源。
示例性地,当第一通信模组为NR模组,第二通信模组为LTE模组,且用于SL传输时,本申请实施例中“终端设备的第一通信模组在资源选择窗对应的候选资源集合中排除第一候选资源;其中,第一候选资源与第一预留资源有重叠,第一预留资源为用于传输第二通信模组支持的网络制式的控制信息的资源。”还可以理解为:对于周期性预留的NR SL传输,NR模组的物理层进一步排除一部分候选资源(即第一候选资源),这些候选资源与LTE模组发送的辅助信息中其他LTE sidelink UE周期性预留的资源对应的PSCCH使用的资源(即第一预留资源)有重叠。
应理解,在一种实现中,上述第一预留资源为用于传输第二通信模组支持的网络制式的控制信息的资源可以理解为:第一预留资源为用于传输第二预留资源对应的控制信息的资源,第二预留资源为第二通信模组(例如LTE模组)感知到的传输)所预留的资源。可选的,在另一种实现中,上述第一预留资源为用于传输第二通信模组支持的网络制式的控制信息的资源可以理解为:第一预留资源为为第二通信模组支持的网络制式配置的资源池
中用于传输控制信息的资源,即第一预留资源为资源选择窗内所有可以用于传输第二通信模组支持的网络制式的数据对应的控制信息的资源。其中上述资源池可以为LTE sidelink非相邻结构的资源池。
举例来说,请参见图6,图6是本申请实施例提供资源选择的场景示意图。如图6所示,为第二通信模组支持的网络制式配置的资源池中,所有的控制信道使用的资源位于资源池较低的频率范围,而所有数据信道使用的资源位于资源池较高频率范围,假设为第二通信模组支持的网络制式配置的资源池中包括SCI1,SCI2,SCI3,Data1,Data2和Data3,其中,SCI1对应Data1,SCI2对应Data2,SCI3对应Data3。UE1在时间单元n触发资源选择/重选,在一种实现中,第一预留资源为用于传输第二预留资源对应的控制信息的资源,第二预留资源为第二通信模组感知到的传输所预留的资源,其中,假设第一预留资源为SCI3对应的资源,那么第二预留资源即为Date3对应的资源。可选的,在另一种实现中,若第一预留资源为为第二通信模组支持的网络制式配置的资源池中用于传输控制信息的资源,那么第一预留资源即为图6中用于传输控制信息的资源,即位于资源池较低的那部分频率范围的资源。
在一些可行的实施方式中,终端设备的第一通信模组还可以基于配置确定是否排除第一候选资源。也就是说,终端设备的第一通信模组可以接收指示信息,该指示信息用于指示是否排除第一候选资源。示例性地,该指示信息的长度可以为1比特(bit),当该1bit的取值为1时,指示排除第一候选资源(即排除与第一预留资源有重叠的候选资源),当该1bit的取值为0时,指示不排除第一候选资源。可选的,终端设备的第一通信模组还可以基于协议预定义或预配置的信息确定是否排除第一候选资源,本申请对此不做限制。
在一些可行的实施方式中,第一预留资源除了与第一候选资源有重叠,第一预留资源的第一参考信号接收功率(reference signal received power,RSRP)参考信号接收功率测量值还需要大于RSRP阈值。也就是说,第一候选资源与第一预留资源有重叠,包括:第一候选资源与第一预留资源有重叠,且第一预留资源的第一RSRP测量值大于RSRP阈值。
应理解,在一种实现中,上述第一RSRP测量值可以为PSSCH上的RSRP测量值,即第一RSRP测量值为第二通信模组支持的网络制式的PSSCH的RSRP测量值。这里,该PSSCH为LTE模组感知到的传输资源上传输的PSSCH(即数据信息),该PSSCH对应的SCI/PSCCH(即控制信息)指示了后续周期性传输的PSSCH使用的资源,其中,位于资源选择窗中的后续周期性传输的PSSCH使用的资源对应的PSCCH使用的资源为第一预留资源。
举例来说,请一并参见图6,在图6所示的场景中,第一RSRP测量值为Data1上的RSRP测量值,即PSSCH为Data1,该PSSCH对应的SCI/PSCCH(即控制信息)为SCI1,SCI1指示了后续周期性传输的PSSCH使用的资源,即指示了Data2和Data3使用的资源,其中,位于资源选择窗中的后续周期性传输的PSSCH使用的资源为Data3,Data3对应的PSCCH使用的资源为SCI3,即第一预留资源为SCI3。
可选的,在另一种实现中,上述第一RSRP测量值为对PSSCH上的RSRP测量值进行功率补偿后得到的RSRP测量值,示例性地,补偿方式可以存在如下2种:
①第一RSRP测量值满足:
其中,RSRPused表示第一RSRP测量值,表示PSSCH上测量的RSRP测量值,α表示可配的系数因子,X表示可配补偿功率增益。其中,α与X可同时使用,亦可仅使用一个,在此不做限制。这里,α和X可以由高层配置的,或者协议预定义的,或者是预配置的,在此不做限制。
②第一RSRP测量值满足:
其中,RSRPused表示第一RSRP测量值,表示PSSCH上测量的RSRP测量值,MPSSCH表示PSSCH占用的物理资源块PRB的数量,MPSCCH表示PSCCH占用的PRB数量。这里,MPSSCH为感知到的当前传输PSSCH使用的PRB数量,MPSCCH为感知到的当前传输PSCCH使用的PRB数量。
示例性地,当第一通信模组为NR模组,第二通信模组为LTE模组,且用于SL传输时,本申请实施例中“终端设备的第一通信模组在资源选择窗对应的候选资源集合中排除第一候选资源;其中,第一候选资源与第一预留资源有重叠,且第一预留资源的第一RSRP测量值大于RSRP阈值,第一预留资源为用于传输第二通信模组支持的网络制式的控制信息的资源。”还可以理解为:对于周期性预留的NR SL传输,NR模组的物理层进一步排除一部分候选资源(即第一候选资源),这些候选资源与LTE模组发送的辅助信息中其他LTE sidelink UE周期性预留的资源对应的PSCCH使用的资源(即第一预留资源)有重叠,且该LTE sidelink周期性第一预留资源的RSRP测量值大于RSRP阈值。
在一些可行的实施方式中,第一预留资源除了与第一候选资源有重叠,第一预留资源上传输的控制信息所指示的优先级还可以低于第一通信模组的待传输数据的优先级。也就是说,第一候选资源与第一预留资源有重叠,包括:第一候选资源与第一预留资源有重叠,且第一预留资源上传输的控制信息所指示的优先级低于第一通信模组的待传输数据的优先级。应理解,第一通信模组的待传输数据为本次资源选择待传输的数据。
示例性地,当第一通信模组为NR模组,第二通信模组为LTE模组,且用于SL传输时,本申请实施例中“终端设备的第一通信模组在资源选择窗对应的候选资源集合中排除第一候选资源;其中,第一候选资源与第一预留资源有重叠,且第一预留资源上传输的控制信息所指示的优先级低于第一通信模组的待传输数据的优先级。”还可以理解为:对于周期性预留的NR SL传输,NR SL module的物理层进一步排除一部分候选资源,这些候选资源与LTE module发送的辅助信息中其他LTE sidelink UE周期性预留的资源对应的PSCCH使用的资源(即第一预留资源)有重叠,且LTE第一预留资源上待传输数据的优先级低于NR待传输数据的优先级。
在本申请实施例中,通过从为NR传输进行的资源选择过程中确定的候选资源集合中排除LTE周期性传输对应的PSCCH使用的资源,可避免由于NR模组资源选择时将LTE周期性传输对应的PSCCH使用的资源作为候选资源,而造成LTE sidelink与NR sidelink传输使用相同资源,造成资源冲突问题,进而提高了通信的可靠性。
