具体实施方式
图1为本申请的应用场景示意图,如图1所示,本申请的应用场景中包括:基站、中继设备和远程设备,中继设备中转基站和远程设备之间的数据和控制信息。其中,基站可以是长期演进(Long Term Evolution,简称LTE)系统中的演进型基站(evolved NodeB,简称eNB)、接入点(access point,AP)或者中继站,也可以是第五代移动通信(5Generation,5G)系统中的基站(如gNB或传输点(Transmission Point,TRP))等。中继设备和远程设备都可以是用户设备的一种。用户设备,可以称之为终端设备、移动台、终端或移动终端等,该用户设备可以经无线接入网(Radio Access Network,RAN)与一个或多个网络设备进行通信。用户设备可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等,例如,用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动设备。用户设备也可以是物联网设备,例如表类终端,穿戴设备,物流跟踪,或卫视等物联设备。在不同的场景中,中继设备和远程设备可能不同;例如:在车联网场景中,中继设备可以为路边单元(Road Side Unit,RSU)等,远程设备可以为车载单元(On board Unit,OBU)、车载设备(Vehicle UE,V-UE)或行人手持终端(Pedestrian UE,P-UE)等;在物联网场景中,中继设备可以是手机、具有通信能力的手表、物联网设备(Internet of Things device,IoT device)或具有移动终端的计算机等,远程设备可以是可穿戴设备(如:智能手环或智能手表)、IoT设备等,图1以物联网场景为例示出,对此,本申请不做限制。
本申请中继设备通过两级控制信息调度远程设备,其中,第一控制信息(即第一级控制信息)用于指示哪些远程设备被调度,远程设备根据第一控制信息确定自己是否被中继设备调度,若被中继设备调度,则在指定位置获取其对应的第二控制信息(即 第二级控制信息),第二控制信息携带远程设备的调度信息,从而,远程设备获取其调度信息。其中,远程设备可以通过在第一控制信息中携带的被调度的远程设备对应的第二控制信息的位置信息确定指定位置;远程设备也可以根据第一控制信息确定自己是否被中继设备调度,若被中继设备调度,则根据预设规则确定指定位置,由于远程设备对应的第二控制信息的位置信息可以通过第一控制信息确定,因此,缩小了远程设备的盲检范围,降低了远程设备的功耗。
本申请下述各实施例中可能涉及到的概念:
资源块(resource block,RB)是指频率资源上M个子载波对应的带宽,比如M=12;
物理资源块(Physical Resource block,PRB):是指由频率资源上K个RB以及时间资源上L个时隙(slot)所组成的时频资源(Time-Frequency resource),比如K=1,L=1;
物理资源块对(PRB pair):是指由相同RB位置两个PRB组成的资源,即频率资源上K个RB以及时间资源上2L个时隙(slot)所组成的时频资源,比如K=1,L=1;
时频资源最小的单元称为资源单元(Resource Element,RE),是指频率上Q个子载波和时间上P个物理符号(比如正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号或单载波频分多路复用(Single carrier-Frequency Division Multiplexing,SC-FDM)符号)的资源,比如Q=1,P=1;时频资源由一个或多个RE组成。
本申请中,如无特别指出,资源指时频资源。当前标准中,一个SCI(也称SA)占用1个PRB pair;而旁路(sidelink)中数据(data)的调度在时间上以子帧为单位(2个slot),频率上的RB数由SCI来指示。
前述概念的定义是以LTE协议为基础。在新的通信系统技术或者各种演进系统技术中,比如5G,可能会采用不同的概念来定义,或者不同的参数值来定义;例如M可能不是12,SCI也可能不是占用1个PRB pair。本申请从便于理解的角度采用LTE中的概念描述,但并不限定于此。
下面以几个具体地实施例对本申请的技术方面进行说明,这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
图2为本申请设备通信方法实施例一的流程示意图,如图2所示:
S201:中继设备从候选资源集中确定第一资源。
候选资源集是指资源池中可用于传输第一控制信息的资源的集合,候选资源集为资源池的部分资源,资源池中的资源用于中继设备和远程设备之间的通信,资源池中包含候选资源集。
第一资源是指传输第一控制信息所使用的资源,其可能是候选资源集中的任一资源。
其中,候选资源集可以根据如下预设规则确定:
例如:确定资源池中间的至少一个RB的位置对应的一个或多个资源组成候选资源集。
或者,确定在同步信号所处频率资源位置且距离同步信号第一预设时间距离的位 置对应的一个或多个资源组成候选资源集,同步信号为中继设备发送给远程设备的同步信号。
或者,确定从直接帧号(Direction Frame Number,DFN)#0或系统帧号(System Frame Number,SFN)#0偏移第二预设时间距离以预设周期出现的位置对应的一个或多个资源组成候选资源集。其中,DFN也称为D2D帧号。
可选地,S201之前还可以包括:S200:
S200:中继设备获取资源池的配置信息。
可选地,中继设备获取资源池的方式包括但不限于如下几种实现方式:
其中一种可能的实现方式:基站或网络侧设备向中继设备发送资源池的配置信息,中继设备根据资源池的配置信息获得资源池时间频率位置和/或资源池大小等信息。具体地,基站可以通过蜂窝链路上传输的控制信息向中继设备发送资源池的配置信息。
另一种可能的实现方式:中继设备通过预配置的方式获取资源池的配置信息;例如由协议规定,或者根据不同地区无线管理机构的许可预先配置通过网络侧设备获取。
S202:中继设备在第一资源发送第一控制信息。
中继设备可以根据业务和资源的情况确定被中继设备调度的远程设备。
其中,第一控制信息用于指示被中继设备调度的远程设备的信息(也可表示为远程设备是否被中继设备调度的信息)以及被调度远程设备对应的第二资源的位置信息。
假设,中继设备调度3个远程设备,则其在第一控制信息中指示3个远程设备被调度,3个远程设备分别为远程设备1、远程设备2和远程设备4;传输第一控制信息的第一资源,以及传输远程设备1的第二控制信息的第二资源,传输远程设备2的第二控制信息的第二资源,传输远程设备2的第二控制信息的第二资源如图3所示。其中,第一控制信息可以周期性地发送。
一种可能的实现方式中,被中继设备调度的远程设备的信息以及被调度远程设备对应的第二资源的位置信息可以被携带在第一控制信息对应的旁路控制信息SCI中。在SCI中为每个被中继设备调度的远程设备定义两个域,如图4所示,一个域用于指示被中继设备调度的远程设备的信息,例如:远程设备的信息可以为远程设备的本地ID(Local ID)或者临时ID,用N比特标识一个远程设备,最多可以标识2N个远程设备。图4中通过3比特指示远程设备的ID,分别为C7、C6和C5,可用于标识8个远程设备的信息。另一个域用于指示第二资源的位置信息,图4中以5比特为例,分别为C4、C3、C2、C1和C0。
另一种可能的实现方式中,被中继设备调度的远程设备的信息以及第二资源的位置信息被携带在所述第一控制信息对应的数据的媒体接入控制控制单元(Media Access Control Control Element,MAC CE)中。
这种方式与图4所示方式类似,不同的是图4中在SCI中为每个中继设备调度的远程设备定义两个域,而这种方式在第一控制信息对应的数据的MAC CE中为每个中继设备调度的远程设备定义两个域,两个域的定义方式与图4类似,此处不再赘述。
再一种可能的实现方式中,被中继设备调度的远程设备的信息被携带在所述第一控制信息对应的旁路控制信息SCI中,所述第二资源的位置信息被携带在所述第一控制信息对应的数据的MAC CE中。如图5所示,第一控制信息对应的SCI指示被中继设 备调度的远程设备的信息可以通过比特映射(bitmap,也可称为位图)的方式指示,与中继设备关联的每个远程设备对应bitmap中的一比特。图5中通过8比特的bitmap来表示中继设备关联的远程设备是否被调度,通过设置对应比特位的值表示对应的远程设备是否被调度,例如:若1表示被调度,0表示未被调度,若某个远程设备被调度,则设置该远程设备对应的比特位的值为1。若0表示被调度,1表示未被调度,若某个远程设备被调度,则设置该远程设备对应的比特位的值为0。在图5中,假设比特位的值为1表示被调度,则远程设备1、远程设备2和远程设备4被调度,其余远程设备未被调度。第一控制信息对应的数据的MAC CE中携带第二资源的位置信息,如图5所示。远程设备先检测第一控制设备对应的SCI,确定自身是否被调度,若被调度,则检测第一控制信息对应的数据的MAC CE,以获取第二资源的位置信息。在图5所示方式中,只有被调度的远程设备需要解调第一控制信息对应的数据的MAC CE。
图6为本申请中继设备通过第一控制信息和第二控制信息调度远程设备的示意图。其中图中(a)示意了第一控制信息在SCI中传输的情况;图中(b)示意了第一控制信息在SCI和data的MAC CE上传输的情况。这里,仅通过示例说明了PSCCH和PSSCH资源池频分复用时的情况。本申请的方法同样适用于PSCCH和PSSCH资源池时分复用的情况。
S203:中继设备根据确定的第二资源的位置信息,在第二资源发送被中继设备调度的远程设备的第二控制信息。
其中,第二控制信息中包含调度信息。
可选地,中继设备在发送被调度的远程设备的第二控制信息之前,还可以通过被调度的远程设备的相关信息对其对应的第二控制信息进行加扰。例如:相关信息可以是标识信息,例如可以是全局ID,或者小区无线网络临时标识(CellRadioNetworkTemporaryIdentifier,C-RNTI),层2ID等;如:远程设备1被中继设备调度,则远程设备1的第二控制信息通过远程设备1的标识信息如全局ID进行加扰,以使远程设备1对第二控制信息进行正确解扰,而其他远程设备不能对远程设备1的第二控制信息进行正确解扰。
可选地,第二控制信息中还可以包括第二指示信息,第二指示信息用于指示第二控制信息为调度中继设备的传输资源的控制信息;或者,第二控制信息为调度远程设备的传输资源的控制信息。即第二指示信息用于指示该第二控制信息为旁路上行链路(Sidelink UL)控制信息还是旁路下行链路(Sidelink DL)控制信息。第二指示信息可以通过1比特表示,例如:0表示旁路下行链路控制信息,1表示旁路上行链路控制信息。旁路下行链路指中继设备到远程设备的链路;旁路上行链路指远程设备到中继设备的链路。
相应地,远程设备在第一资源接收第一控制信息,并根据第二资源的位置信息,确定第二资源,在第二资源接收第二控制信息。
其中,第一资源、第一控制信息、第二资源和第二控制信息的详细描述,参见S200-S203中相关部分的详细描述,此处不再赘述。
本实施例,通过中继设备从候选资源集中确定第一资源,在第一资源发送第一控制信息,在第二资源发送第二控制信息,由于中继设备在第一控制信息中指示被中继 设备调度的远程设备以及第二资源的位置信息,因此,远程设备可以通过在第一资源接收到的第一控制信息确定其是否被调度,以及若其被调度,其对应的第二资源的位置信息,在其对应的第二资源接收其对应的第二控制信息,获得其调度信息,相当于远程设备盲检第一控制信息,检测到第一控制信息之后即可直接确定用于传输第二控制信息的第二资源的位置信息,即,无需盲检第一资源到第二资源之间的资源,从而,缩小了远程设备的盲检范围,降低了远程设备的功耗。
在图2所示实施例的基础上,进一步地,可以使远程设备预先获知中继设备可用于传输第一控制信息的候选资源集的位置信息;以使得远程设备根据候选资源集的位置信息,在候选资源集的资源检测第一控制信息,进一步地,缩小了远程设备的盲检范围,进一步地降低了远程设备的功耗。
远程设备预先获知中继设备可用于传输第一控制信息的候选资源集的位置信息的方式包括但不限于如下两种:
其中,一种可能的实现方式:通过预配置的方式使远程设备获知候选资源集的位置信息。
另一种可能的实现方式,通过中继设备向远程设备发送第一指示信息的方式使得远程设备获知候选资源集,其中,第一指示信息用于指示候选资源集的位置信息,候选资源集的位置信息可以包括初始资源的位置信息以及候选资源的周期。
其中,中继设备向远程设备发送第一指示信息的方式包括但不限于如下几种:一种可能的实现方式:中继设备通过广播消息向远程设备发送第一指示信息;例如:中继设备通过物理旁路广播信道(Physical Sidelink Broadcast Channel,PSBCH)向远程设备发送第一指示信息。或者,中继设备通过发现消息(discovery message)向远程设备发送第一指示信息。另一种可能的实现方式:所述中继设备通过无线资源控制(Radio Resource Control,RRC)消息向远程设备发送所述第一指示消息。
在上述各实施例中,若第一控制信息和第二控制信息可以共享资源时,可以通过第一控制信息与第二控制信息对应的SCI采用不同的(Demodulation Reference Signal,DMRS)、前导序列或者循环冗余校验(Cyclic Redundancy Check,CRC)来区分第一控制信息和第二控制信息。
图7为本申请设备通信方法实施例二的流程示意图,图7与图2所示实施例的不同的是,在图2所示实施例中,第二资源的位置信息直接被携带在第一控制信息中,而在图7所示实施例中,第二资源的位置信息采用隐式的方式指示,如图7所示:
S701:中继设备在第一资源发送第一控制信息。
其中,第一控制信息用于指示被中继设备调度的远程设备的信息。
S702:远程设备确定第一控制信息中指示的被中继设备调度的远程设备的信息是否包含其信息,若包含根据预设规则确定第二资源。
其中,预设规则可以是预先配置的;中继设备可以在与远程设备关联时,将预设规则发送给远程设备,或者,中继设备可以通过广播信息将预设规则发送给远程设备,或者,预设规则也可以由标准指定等,对此,本申请不做限制。
S703:中继设备在第二资源发送被调度的远程设备的第二控制信息。
相应地,远程设备在第二资源接收其第二控制信息。
本实施例,通过中继设备在第一资源发送第一控制信息,远程设备确定第一控制信息中指示的被中继设备调度的远程设备的信息是否包含其信息,若包含根据预设规则确定第二资源,中继设备在第二资源发送被调度的远程设备的第二控制信息,远程设备在第二资源接收其第二控制信息,由于第二资源是预先配置的,远程设备在确定其被调度后,在第二资源接收其第二控制信息,缩小了远程设备的盲检范围,降低了远程设备的功耗。
图8为本申请设备通信方法实施例三的流程示意图,本实施例的方法由中继设备执行,本实施例的方法如下:
S801:获取资源池的配置信息。
S802:配置控制信息和资源。
S803:发送公共控制信息。
其中,公共控制信息中携带特定的远程设备的信息,以及特定的远程设备的控制信息的位置信息。特定的远程设备指被中继设备调度的远程设备。
S804:发送特定的远程设备的控制信息。
本实施例中各步骤的详细描述可以参见上述图2或图7中相应步骤的详细描述,此实施例不再赘述。本实施例的实现原理和技术效果类似,此处不再赘述。
图9为本申请设备通信方法实施例四的流程示意图,本实施例的方法由远程设备执行,本实施例的方法如下:
S901:检测公共控制信息。
S902:确定是否被中继设备调度,若是,执行S903,若否,结束。
S903:检测特定的远程设备的控制信息。
本实施例中各步骤的详细描述可以参见上述图2或图7中相应步骤的详细描述,此实施例不再赘述。本实施例的实现原理和技术效果类似,此处不再赘述。
