具体实施方式
下面结合附图和实施例对本公开进行描述。可以理解的是,此处所描述的具体实施例仅仅用于解释相关发明,而非对该发明的限定。另外还需要说明的是,为了便于描述,附图中仅示出了与有关发明相关的部分。需要说明的是,在不冲突的情况下,本公开中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本公开。
NR定位使能了两种新的参考信号,分别是下行定位参考信号(Positioning reference signal,PRS)和上行定位参考信号(Sounding reference signal for positioning,SRS pos)。由于两种参考信号图样(pattern)采用对称设计,下面以PRS为例描述定位参考信号的资源配置图样。每个资源(resource)在时域上占用连续符号,频域上采用梳齿结构(staggering);不同符号之间的资源元素(Resource element,RE)偏移(offset)。如图1所示,图1中为梳齿为4的PRS resource在一个物理资源块(PRB,含12RE)上的pattern,其时域上占4连续符号,频域comb size=4,即频域是每隔4RE放一个RE;每个符号相对于前一个符号的频域RE offset是固定的,comb size=4的RE offset为{0,2,1,3}。此外,不同resource可以配置不同的首符号的起始资源元素RE偏移(first symbol RE offset),从而实现不同参考信号在频域上的正交复用。
PRS由定位服务器(如位置管理功能(Location Management Function,LMF))配置,对于占用相同时频域资源的PRS,其可以通过为不同发送/接收点(Transmit/Receive Point,TRP)配置不同的first symbol RE offset和静默(muting),实现PRS间正交;SRS pos由服务NR节点(NR Node B,gNB)配置,对于同小区的不同用户设备(User Equipment,UE),基站可以配置其采用不同的first symbol RE offset及循环移位(cyclic shift)实现正交。
可知,NR sidelink支持两种资源分配机制,Mode 1和Mode 2资源分配。Mode 1为基站为终端分配sidelink发送资源的机制,而Mode 2为终端自行选择发送资源的机制。Mode 2资源选择模式为“先听后发”,基于在感知窗口(sensing window)中的资源进行感知,来确定在资源选择窗口(selection window)应该选择的资源;如图2所示,设UE 1在时刻n触发了资源选择,则UE 1可以确定sensing window[n-T_0,n-T_proc,0]和资源选择窗口[n+T_1, n+T_2]。UE 1会在sensing window中检测并解调其他UE发送的第一级sidelink控制信息(1st直连链路控制信息(Sidelink Control Information,SCI),其承载在sidelink控制信道物理直连链路控制信道(Physical SideLink Control Channel,PSCCH)中),根据1st SCI中的资源预留信息(如图2中,两个UE分别预留了后续的两块资源),如果上述预留资源满足预设规则(如,参考信号接收功率(Reference Signal Received Power,RSRP)高于(预)配置的收发优先级对所对应的RSRP门限),则UE 1会自己的候选资源集合中将上述资源排除;完成资源排除流程后,剩下的资源为UE 1可用于发送的候选资源集合。
具体的,UE执行Mode 2资源选择的过程如下:
1)确定资源选择窗口:如果在时隙n触发资源选择,那么资源选择窗口为[n+T1,n+T2]。T1为UE基于实现选择的并满足其中,所述为预设时隙值;如果T2min小于等于剩余包时延(remaining packet delay budget),则T2为UE基于实现选择的并满足T2min≤T2≤remaining packet delay budget;否则,T2等于remaining packet delay budget,其中T2min为高层提供的参数;
2)确定感知窗口:如果在时刻n触发资源选择,那么感知窗口为[n-T0,n-Tproc,0],其中,T0为高层提供的参数,为预设时隙值;
3)感知(Sensing)过程:即在感知窗口中解调其他终端发送的PSCCH(其中携带第一级sidelink控制信息SCI),并收集RSRP信息;
4)排除资源过程:V2X为半双工,UE在自己的发送时隙中无法进行监听,所以只能假设该时隙上其他UE以系统配置的所有可能周期预约的一次/多次资源,与资源选择窗口内的候选资源或者候选资源后的周期性预留资源重叠时,排除所述资源;解码SCI指示的占用资源及后续一次/多次预留资源,与资源选择窗口内的候选资源或者候选资源后的一次/多次预留资源重叠,且RSRP高于一定阈值,排除所述资源;如果剩余资源小于全集的X%,则将RSRP阈值提高3dB,重复资源排除步骤;将可用资源报告给媒体接入控制(Medium Access Control,MAC)层,MAC层进行随机选择。
UE在进行资源感知和资源选择时,以候选单时隙资源(a candidate single-slot resource,R_x,y)为单位进行,其在频域上占用连续的一组子信道 sub-channel(sub-channel包含一组连续的PRB),时域上占一个时隙(slot);即Mode 2资源分配机制所选择的资源在频域上是一整块连续的PRB。
相关技术中,当参与定位的终端处于部分或无网络场景下,没有定位服务器(如LMF)或gNB为参与定位的终端分配参考信号资源时,参与定位的终端采用分布式的资源选择方式(Mode 2资源分配方式)确定参考信号资源将可能出现较频繁的资源冲突的问题;下行定位参考信号(PRS)/上行定位参考信号(SRS pos)采用梳齿结构,在相同时域或频域资源上,可以RE级别复用不同TRP或UE;若待定位终端基于Mode 2资源分配方式自行选择sidelink RS,为了实现RE级别的资源分配粒度,会对相关资源排除流程带来较大影响。本公开实施例由第一终端为终端组分配sidelink RS资源,第一终端对分配给组中终端的sidelink资源进行控制、且为第一终端对分配给不同组中终端的sidelink资源进行控制提供了可能,在尽量复用sidelink资源选择机制的前提下,提升不同终端之间sidelink RS复用度,可规避潜在的终端组间的参考信号资源冲突。
本公开实施例提供了一种资源分配方法,如图3所示,应用于第一终端,包括:
步骤301:为一个组中的终端分配sidelink参考信号(Reference Signal,RS)资源;其中,所述第一终端是预配置的、或者所述第一终端包括所述一个组中的待定位终端。
这里,本公开所述第一终端是预配置的,包括:所述第一终端是网络(预)配置的,所述(预)配置代表配置或预配置。
实际应用时,所述终端可以称为UE,还可以称为用户。所述待定位终端为发起定位请求的终端。
实际应用时,可根据不同的部署场景,所述第一终端存在如下两种方案:
A、第一终端为(预)配置的:该场景下的第一终端类似于一个区域内的LMF,如图4所示,第一终端能为各组参与定位的终端分配正交的sidelink RS资源,尽量避免区域内不同终端之间的资源碰撞(各组参与定位的终端对应的终端组可以称为定位组,该方案可对区域内的不同定位组进行集中式资源分配,避免区域内不同定位组之间定位参考信号资源冲突);
B、第一终端为一个组中的待定位终端(该方案在实际应用时,设定的区域中可以不存在方案A中类似LMF的终端):待定位终端为自己和组内成员确定并分配正交的sidelink RS资源,如图5所示。对于不同的组,待定位终端仅能为自己所在组中的终端进行sidelink RS资源分配。
一个实施例中,所述分配sidelink RS资源之前,该方法还包括:
确定组中终端的标识信息和/或数量。
在实际应用时,所述终端的标识信息包括如下至少之一:UE标识(Identifier,ID)、UE应用层ID、UE层2(Layer 2,L2)ID、UE层1(Layer1,L1)ID、UE源ID、UE目的ID、UE组成员ID等。
一个实施例中,在所述第一终端包括所述一个组中的待定位终端的情况下,所述确定组中终端的标识信息和/或数量,包括:
发送所述第一终端的定位需求;
接收至少一个第二终端发送的第一信息,所述至少一个第二终端属于第一组,所述第一信息包括对所述定位需求的回复信息;所述第二终端能为所述第一终端提供定位服务;
确定所述第一组中终端的标识信息和/或数量;其中,所述第一组包括所述第一终端和所述至少一个第二终端。
这里,实际应用时,所述发送所述第一终端的定位需求的类型包括如下至少之一:广播、组播、单播。
在实际应用时,第一终端发送定位需求,收到N(N不小于1)个第二终端回复的第一信息,则可以确定组中第二终端的数量为N,组中总终端数量为N+1。第二终端发送的第一信息可以是用于第一终端进行定位的辅助信息,该辅助信息中携带第二终端ID或应用层ID或L2 ID,第一终端可以根据上述第二终端的ID信息确定终端的标识信息;
或者,第二终端发送的第一信息所关联的sidelink控制信息中,携带有第二终端的L1 ID、目的ID、组成员ID等信息,第一终端可以根据上述第二终端的ID信息确定终端的标识信息。
一个实施例中,在所述第一终端是预配置的情况下,所述确定组中终端的标识信息和/或数量,包括:
接收第三终端发送的第二信息,所述第二信息用于请求sidelink RS资源;第二组包括所述第三终端和至少一个第四终端,所述第四终端能为所述第三终端提供定位服务;
确定所述第二组中终端的标识信息和/或数量;其中,
所述第二信息包括以下至少之一:
所述第二组的组标识;
所述第二组中终端的标识信息和/或数量。
在实际应用时,所述第三终端发送所述第二信息之前,发送定位需求;收到N(N不小于1)个第四终端回复所述定位需求,则可以确定组中第四终端的数量为N,组中总终端数量为N+1。第四终端回复的信息可以是用于第三终端进行定位的辅助信息,该辅助信息中携带第四终端ID或应用层ID或L2 ID,第三终端可以根据上述第四终端的ID信息确定终端的标识信息;
或者,第四终端回复的信息所关联的sidelink控制信息中,携带有第四终端的L1 ID、目的ID、组成员ID等信息,第三终端可以根据上述第四终端的ID信息确定终端的标识信息。
一个实施例中,所述分配sidelink RS资源之前,所述方法还包括:
接收第一配置信息,所述第一配置信息包含资源池与区域标识之间的关联关系,所述第一配置信息是在网络侧预配置的;
利用所述第一配置信息,为一个组中的终端分配sidelink RS资源。
在实际应用时,对于第一终端是预配置的情况,区域内的同一个第一终端所调度的不同组之间可以有效避免资源冲突,但不同第一终端之间依旧有可能出现资源冲突;对于第一终端包括所述一个组中的待定位终端的情况,不同的第一终端仅能保证自己的组内终端之间不存在资源冲突,但不同的第一终端之间都是分布式的资源选择机制,依旧有可能出现组之间的资源冲突。因此,可在网络侧预配置资源池与区域标识(如zone ID)之间的关联关系;对于同一个区域标识,可确定多个资源池或资源池集合;相邻的区域之间采用正交的资源池或资源池集合;所述资源池的确定方式可以是(预)配置、或利用RP ID对区域集编号(zone set number)取模确定;如图6所示。
一个实施例中,在所述第一终端是预配置的情况下,所述利用所述第一 配置信息,为一个组中的终端分配sidelink RS资源,包括:
确定第三信息,所述第三信息包含第一终端的区域标识和/或第四终端的区域标识,所述第四终端属于第二组,所述第二组包括第三终端和至少一个第四终端,所述第四终端包括能为所述第三终端提供定位服务的终端;
利用所述第一配置信息确定与所述第三信息对应的资源池;
执行sidelink资源选择过程从确定的资源池为所述第二组中的终端分配sidelink RS资源。
这里,在实际应用时,所述第一终端可根据自己的区域标识和第四终端的区域标识(提供定位服务的终端会在辅助信息(反馈定位需求的信息)中携带自己的位置坐标)以及所述资源池与区域标识之间的关联关系,为组中的终端分配sidelink RS资源。对于多个(至少两个)组的情况下,所述第一终端可分别为多个组中每个组中的终端分配sidelink RS资源,具体分配方式同上文描述。因此,本实施例基于资源池与区域标识之间的关联关系以及所述第三信息为所述第二组中的终端分配sidelink RS资源,可提升不同终端之间sidelink RS复用度,规避潜在的终端组间的(定位)参考信号资源冲突。
一个实施例中,在所述第一终端包括所述一个组中的待定位终端的情况下,所述为一个组中的终端分配sidelink RS资源,包括:
确定第二终端的区域标识;所述第二终端属于第一组,所述第一组包含所述第一终端和至少一个第二终端;所述第二终端能为所述第一终端提供定位服务;
利用所述第一配置信息确定第二终端的区域标识对应的资源池;
执行sidelink资源选择过程从确定的资源池为所述第一组中的终端分配sidelink RS资源。
这里,在实际应用时,对于不同的组,虽然待定位终端仅能为自己所在组中的终端进行sidelink RS资源分配,但是每个组中的第一终端均可利用所述第一配置信息确定第二终端的区域标识对应的资源池,同样可规避潜在的终端组间的(定位)参考信号资源冲突。
需要说明的是,本公开所述执行sidelink资源选择过程详见本公开上文所述UE执行Mode 2资源选择的过程,此处不再详述。
这里,在实际应用时,所述第一终端可根据第二终端的区域标识以及所述资源池与区域标识之间的关联关系,为组中的终端确定可用的候选资源池集合,并在集合中确定sidelink RS资源。
一个实施例中,所述方法还包括:
通过高层信令接收配置的资源池信息。
其中,所述高层(higher layer)可包括MAC层。

sidelink RS资源的时域资源信息;
sidelink RS资源的频域资源信息;
sidelink RS资源comb size;
首符号的起始RE偏移。
在实际应用时,如果所述第一终端处于完全被网络覆盖(in-coverage)的场景,且支持Mode 1资源分配方式,可以向网络侧(如:gNB)请求sidelink RS资源;如果所述第一终端处于无网络覆盖(out-of-coverage)的场景,或支持Mode 2资源分配方式,可以基于感知(sensing)确定sidelink RS资源。
在本实施例中,所述第一终端依旧基于sidelink资源分配机制为某一组的终端确定成块的sidelink RS资源(即频域上占用连续的多个子信道或PRB),而在成块的资源内,组内终端再进一步进行RE级别(level)的资源复用,如图7所示。具体可以有两种分配方案:
1)第一终端分别向组内每一个终端通知相应终端在成块的sidelink RS资源中占用的资源,不同终端的sidelink RS资源为RE级别正交;
2)第一终端向组内每一个终端通知成块的sidelink RS资源,不同终端可以利用自己的标识信息(如成员(member)ID)对comb size N取模确定各自占用的资源,不同终端的标识信息对应不同的首符号的起始资源元素RE偏移(first symbol RE offset)。
