应理解,说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因此,在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外,这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本公开的各种实施例中,应理解,下述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本公开实施例的实施过程构成任何限定。
另外,本文中术语“系统”和“网络”在本文中常可互换使用。
在本申请所提供的实施例中,应理解,“与A相应的B”表示B与A相关联,根据A可以确定B。但还应理解,根据A确定B并不意味着仅仅根据A确定B,还可以根据A和/或其它信息确定B。
本公开实施例中,接入网的形式不限,可以是包括宏基站(Macro Base Station)、微基站(Pico Base Station)、Node B(3G移动基站的称呼)、增强型基站(eNB)、家庭增强型基站(Femto eNB或Home eNode B或Home eNB或HeNB)、中继站、接入点、远端射频模块(Remote Radio Unit,RRU)、射频拉远头(Remote Radio Head,RRH)等的接入网。用户终端可以是移动电话(或手机),或者其他能够发送或接收无线信号的设备,包括用户设备、个人数字助理(Personal Digital Assistant,PDA)、无线调制解调器、无线通信装置、手持装置、膝上型计算机、无绳电话、无线本地回路(Wireless Local Loop,WLL)站、能够将移动信号转换为WiFi信号的客户终端(Customer Premise Equipment,CPE)或移动智能热点、智能家电、或其他不通过人的操作就能自发与移动通信网络通信的设备等。
Rel-16阶段的NR sidelink,物理直通链路控制信道(Physical sidelink control channel,PSCCH)与物理直通链路共享信道(Physical sidelink shared channel,PSSCH)采用时分复用(time division multiplexing,TDM)+频分复用 (frequency division multiplexing,FDM)的方式,并引入了2nd-stage直通链路控制信息(sidelink control information,SCI),其余数据(data)由PSSCH承载;1st-stage SCI由PSCCH承载,用于指示当前传输块(Transport Block,TB)占用的时频资源位置、优先级、周期以及对应的调制和编码方案(Modulation and coding scheme,MCS)等信息,并没有引入相应的sidelink PRS(即SL-PRS)。
对于PRS频域pattern(图样)的说明:
频域pattern为PRS采用的梳齿状尺寸,以及在每个时域符号上的每个RB中的起始位置等信息,这些信息具体可以包括但不限于以下内容:梳状尺寸(comb size)、起始符号的每个RB上的起始映射RE位置、每个符号上RE粒度的映射偏移信息(RE offset)。对于每个符号上均是重复映射的情况,则只需要频域中每个RB内的RE映射位置即可。如图1-2所示,对于UE1来说,comb size=4,起始符号的每个RB上起始映射RE位置为index=0,每个符号上的REoffset={0,2,1,3}。
当多个UE共享相同的PRS专用资源,为了保证不同UE之间发送的PRS正交性,各个发送UE的PRS资源映射位置以及使用的正交覆盖码(Orthogonal Cover Code,OCC)(或循环移位(cyclic shift,CS))可以与发送或者接收UE的用户标识信息(source ID等)或者与PRS请求信令的映射资源位置等相关联,或者由网络配置。
PRS序列可以采用Gold序列(对应OCC)或者ZC序列(对应CS循环移位)。
对于Rel-16 NR positioning,主要引入两种用于定位的参考信号:下行定位参考信号PRS与用于定位的上行探测参考信号SRS for positioning。
下行定位参考信号PRS采用Gold序列,引入了PRS资源,PRS资源集,PRS定位频率层等设计。PRS资源频域可以采用梳齿结构,时域可以占用连续多个正交频分复用技术(Orthogonal Frequency Division Multiplexing,OFDM)符号。采用单端口,最大带宽不能超过272物理资源块(physical resource block,PRB)s,最小带宽不能低于24PRBs。
用于定位的上行探测参考信号(SRS for positioning,SRS-POS)采用ZC 序列,在时域上可以连续占用多个OFDM符号,频域上也是采用梳齿结构,便于支持多个SRS-POS在同一个OFDM符号上频分复用。采用单端口,相比两端口发送,单端口的优势在于可以提高SRS-POS信号在基站接收机侧的功率谱密度,从而可以提高SRS-POS信号的覆盖范围和质量。频域上支持的最大带宽为272RBs,最小带宽为4RBs。SRS-POS支持周期性、半持续、非周期三种资源类型配置。
Release 16 NR定位支持“无线接入技术无关(RAT-independent)”的定位技术,包括GNSS、大气压力传感器定位、WLAN定位、惯导定位、蓝牙定位、地面信标系统定位。
Release 16 NR定位研究了“RAT-dependent”以及混合定位技术以提高定位精度。主要方案为:gNB周期性发送下行PRS,支持到达时间差(Time Difference of Arrival,DL-TDOA)、发射角(Angle of Departure,DL-AoD)测量、增强小区身份标识(Enhanced Cell Identification,E-CID)检测;终端发送用于定位的上行SRS,支持UL-TDOA、UL-信道到达角度(Angle of Arrival,AoA)测量;支持上下行组合进行往返时延(Round Trip Time,RTT)测量,可基于多个基站测得Multi-RTT进行位置定位。
NR/LTE positioning的整体定位流程均受到基站和位置管理功能(Location Management Function,LMF)的管控和调度。
需要说明的是,相关技术中的蜂窝网络定位方案由于存在多个问题,导致无法支持SL定位,这些问题主要包括:(1)需要gNB和LMF交互,对于蜂窝覆盖外场景不支持,而SL定位进行分布式定位处理,可能工作在蜂窝覆盖外场景,无gNB和LMF进行交互;(2)基站gNB多是静止态,而SL定位需要则支持参与定位的节点高速移动;因此其对定位精度、可靠性、时延等方面提出更高需求,因此相关机制无法支持。
具体地,本公开的实施例提供了一种直通链路的资源配置方法、装置及设备,解决了相关技术中缺少适应于直通链路定位的资源配置方案的问题。

作为本公开一可选实施例,对资源池中单个逻辑Slot内各个信道的映射示意说明如下:
(一)当第一设备仅发送定位信道时,定位信道仅用于发送SL-PRS:
可以支持不同的设备采用不同SL-PRS的频域pattern(图样),进行多用 户FDM复用;或者不同用户采用不同的cyclic shift或OCC进行CDM复用;或者不同用户进行TDM复用。
需要说明的是,SL-PRS的频域粒度可以为PRB或者子信道;SL-PRS的频域起始位置可以由高层参数配置或预配置;定位信道的时域符号数和时域起始符号位置通过定位调度信息指示,或者时域符号数由高层参数配置,将整个slot分成特定的时域pattern,例如,如图7-1、图7-2所示,将整个slot时域上分成4部分,第一部分和第二部分固定占用3个符号,第三部分和第四部分固定占用4个符号,设备在使用每一份资源时,时域配置可以遵循这一规则进行资源选择。
(二)当第一设备仅发送定位信道时,定位信道仅用于发送SL-PRS和sidelink定位数据信息:
由于定位信道中包含SL-PRS和定位数据,二者具有相同的时频资源位置,其中SL-PRS采用comb梳状结构映射,定位数据映射在SL-PRS为未占用的RE上。其中,多用户定位信道复用,频域可以采用占用不同频带的FDM复用方式,或者不同用户定位信道还可以采用TDM的复用方式。
需要说明的是,定位信道的频域粒度可以为PRB或者子信道;定位信道的频域起始位置以及频域占用的PRB个数或子信道个数可以通过定位调度信息指示;定位信道的时域符号数和时域起始符号位置可以通过定位调度信息指示,或者时域符号数由高层参数配置,将整个slot分成特定的时域pattern,例如,如图8所示,将整个slot时域上分成4部分,第一部分和第二部分固定占用3个符号,第三部分和第四部分固定占用4个符号。其中,设备在使用每一份资源时,时域配置可以遵循这一规则进行资源选择。
(三)当第一设备发送定位控制信道和定位信道时:
不同设备的定位控制信道可以占用不同的子信道或PRB,分别用于调度各自的定位信道,其中,不同设备的定位信道可以采用TDM的复用方式。
需要说明的是,如果多个设备的定位信道只传输SL-PRS,则多个设备可以采用不同的SL-PRS频域pattern(图样)进行FDM(频分复用);如果设备的定位信道承载了SL-PRS和定位数据,多用户在进行FDM复用的时候,则只能以SL-PRS+定位数据整体进行FDM复用。其中,设备发送的定位信 道中是否包含定位数据是可以通过定位调度信息指示的。
还需要说明的是,定位控制信道的频域起始位置为子信道的起始PRB位置,定位控制信道的频域占用PRB个数可以由高层参数配置或预配置。定位信道的时域符号数和时域起始符号位置可以通过定位调度信息指示,或者时域符号数由高层参数配置,将整个slot分成特定的时域pattern,例如,如图9所示,整个slot中时域上可用于传输定位信道的资源分成3部分用于发送定位信道,第一部分和第二部分固定占用3和4个符号,第三部分固定占用3个符号,设备在使用每一份资源时,时域配置可以遵循这一规则进行资源选择。
其中,定位信道中的SL-PRS的序列生成初始化可以基于定位调度信息中的信息比特进行初始化赋值。
(四)当第一设备发送定位控制信道、定位数据信道和定位信道时,并且资源池内配置定位控制信道与定位数据信道相邻:
每个设备的定位控制信道与定位数据信道在频域上相邻映射的,定位控制信道承载的调度信息可以用于指示定位数据信道和定位信道。
需要说明的是,定位信道的时域符号数和时域起始符号位置、频域PRB、子信道占用个数、频域PRB起始位置、子信道起始位置等可以通过定位调度信息指示,或者时域符号数由高层参数配置,将整个slot分成特定的时域pattern。例如,如图10所示,整个slot中可以用于发送定位信道的时域资源分成3部分用于发送定位信道,其中,第一部分和第二部分固定占用3和4个符号,第三部分固定占用3个符号,设备在使用每一份资源时,时域配置可以遵循这一规则进行资源选择。
对于定位控制信道和定位数据信道的频域配置还可以符合以下至少一项关系:
(1)如图11所示,定位控制信道与定位数据信道在频域的映射可以在一个子信道内。
定位控制信道的起始PRB位置为每个子信道的起始PRB。
(2)如图12所示,定位控制信道在频域上占用的PRB个数小于或等于子信道尺寸(size)。
定位数据信道在频域的调度粒度为子信道。
定位控制信道的起始PRB位置为每个子信道的起始PRB。
(3)如图13所示,定位控制信道在频域上占用的PRB个数等于子信道尺寸(size)的整数倍。
定位数据信道在频域的调度粒度为子信道。
(五)当第一设备发送定位控制信道、定位数据信道和定位信道时,并且资源池内配置定位控制信道与定位数据信道不相邻:
如图14所示,定位控制信道与定位数据信道不相邻,定位控制信道承载的调度信息用于指示定位数据信道和定位信道配置信息:
对于定位控制信道和定位数据信道的频域配置还可以符合以下至少一项关系:
(1)定位控制信道在频域上占用的PRB个数小于等于子信道size。
定位数据信道在频域的调度粒度为子信道。
定位控制信道的起始PRB位置为每个子信道的起始PRB。
(2)定位控制信道在频域上占用的PRB个数等于子信道size的整数倍。
定位数据信道在频域的调度粒度为子信道。
作为本公开一可选实施例,可以将一个完整的slot只用于传输一个设备的定位控制信道和定位信道,或传输一个设备的定位控制信道、定位数据信道和定位信道。
如图17-1所示,表示定位控制信道与定位信道可以采用FDM的复用方式,如图17-2所示,表示定位控制信道与定位信道还可以采用TDM的复用方式。
需要说明的是,若定位控制信道与定位信道的频域带宽不同,可以采用前述实施例中的结构;若定位控制信道与定位信道的频域带宽相同,那么不再需要定位控制信道末尾的GP符号与定位信道起始的AGC符号,可以采用如图18所示的结构,定位控制信道与其调度的定位信道占满整个slot。
本公开实施例中,根据资源池的配置信息,能够在资源池中为第一信道选择传输资源,从而在传输资源上实现第一信道传输,其中,第一信道包括定位信道、定位数据信道和定位控制信道中的至少一项,不同信道可分别用 于传输不同的直通链路相关的定位信号,如此,实现了适应于直通链路定位的资源配置方案,降低了定位信道发生碰撞的概率,提升了定位信道的传输效率,有利于满足Sidelink的定位需求。
