- the NR system supports SL transmission, which is used for direct data transmission between UEs without using network equipment.
- the 5G NR system supports unicast, multicast or broadcast transmission.
- NR SL includes the following channels:
- PSCCH Physical sidelink control channel
- PSSCH Physical sidelink shared channel
- PSDCH Physical sidelink broadcast channel
- PFCH Physical sidelink feedback channel
- PSSCH allocates resources in units of sub-channels, and adopts a continuous resource allocation method in the frequency domain;
- the time domain resources of PSCCH are the number of symbols configured by the higher layer, the frequency domain size is the parameter configured by the higher layer, and the frequency domain of PSCCH
- the domain resource limit is less than or equal to the size of one subchannel, and the PSCCH is located within the range of the lowest subchannel of the PSSCH (as shown in Figure 3).
- NR V2X defines two resource allocation modes (mode), one is mode1, which means the base station schedules resources; the other is mode2, which means the UE itself decides what resources to use for transmission.
- the resource information may come from the base station's broadcast message or Preconfigured information. If the UE works within the range of the base station and there is a Radio Resource Control (RRC) connection with the base station, the resource allocation mode can be mode1 and/or mode2; if the UE works within the range of the base station but does not exist with the base station For RRC connections, the resource allocation mode can only be mode2; if the UE is outside the base station, the resource allocation mode can only be mode2, for example, V2X transmission is performed based on preconfigured information.
- RRC Radio Resource Control
- the TX UE After the resource selection is triggered, the TX UE first determines the resource selection window. The lower boundary of the resource selection window is at the T1 time after the resource selection is triggered. The upper boundary of the resource selection window is at the T2 time after the trigger. T2 is The value selected within the packet delay budget (PDB) transmitted in the Transport Block (TB), and T2 is no earlier than T1.
- PDB packet delay budget
- the UE Before resource selection, the UE needs to determine the candidate resource set for resource selection, based on the reference signal received power (RSRP) measured on the resources within the resource selection window and the corresponding Compare the RSRP threshold (threshold). If the RSRP is lower than the RSRP threshold, then the resource can be included in the alternative resource set.
- RSRP reference signal received power
- the UE randomly selects transmission resources from the candidate resource set. Among them, the UE can also reserve transmission resources for subsequent transmissions during this transmission.
- NR V2X supports a chained resource reservation method, that is, a sidelink control information (SCI) can reserve the current resource, and up to two additional resources can be reserved. In the next resource, another resource can be reserved. Indicates two reserved resources. That is, within the resource selection window, resources can be continuously reserved using dynamic reservation.
- SCI sidelink control information
- RTT positioning technology is a positioning technology used for ranging. As shown in Figure 4 and Figure 5, the RTT positioning process mainly includes the following steps 401 to 406:
- Step 401 The initiating device (or initiating device) sends an RTT measurement request to the responding device (Responding Device). After the Responding Device receives the RTT measurement request, it is ready to receive the RTT measurement signal.
- Step 402 The Initiating Device sends the RTT measurement signal to the Responding Device.
- the Responding Device measures the RTT measurement signal and obtains the Time of Arrival (TOA) measurement time t1.
- TOA Time of Arrival
- Step 403 The Responding Device sends the RTT measurement signal to the Initiating Device at time t2.
- Step 404 The Responding Device sends the RX-TX time difference (ie t2-t1) to the Initiating Device.
- the RX-TX time difference (ie t2-t1) can also be sent in the payload of the RTT measurement signal at time t2.
- Step 405. The Initiating Device measures the RTT measurement signal sent by the Responding Device and obtains the TOA measurement time t3.
- the advantage of RTT positioning is that it does not require absolute synchronization between the Initiating Device and the Responding Device. Because, t2 and t1 only need to refer to the synchronization source of the Responding Device, and t3 and t0 only need to refer to the synchronization source of the Initiating Device.
- the information exchange between the two devices and the results obtained by the device measuring the RTT measurement signal can be considered as part of the measurement report.
- UE1 sends SL PRS1 to UE2, UE2 measures SL PRS1 and gets the first measurement report, then UE2 sends SL PRS2 to UE1, UE1 sends SL PRS3 to UE2, UE2 measures SL PRS3 and gets the second measurement report.
- Measurement report where the first measurement report can be sent together with SL PRS2 or the second measurement report.
- the information transmission method and positioning reference signal transmission method provided by the embodiments of the present application can be applied to the transmission of measurement reports in the RTT positioning method, and can also be applied to any other positioning method (such as downlink arrival time difference (DL)).
- TDOA Time Difference of Arrival
- AOA Angle of Arrival
- AoD Angle of Departure
- RTT positioning can include unilateral RTT positioning or multilateral RTT positioning.

其中,为了便于理解本申请实施例的信息传输方法以及定位参考信号传输方法,现对如下相关技术进行介绍:
一、关于SL
如图2所示,NR系统支持SL传输,用于UE之间不通过网络设备进行直接数据传输。其中,5G NR系统支持单播,组播或广播的传输。另外,NR SL包括如下信道:
物理旁链路控制信道(physical sidelink control channel,PSCCH);
物理旁链路共享信道(physical sidelink shared channel,PSSCH);
物理旁链路广播信道(physical sidelink broadcast channel,PSBCH);
物理旁链路反馈信道(physical sidelink feedback channel,PSFCH);
其中,PSSCH以子信道为单位进行资源分配,频域上采用连续的资源分配方式;PSCCH的时域资源为高层配置的符号数,频域大小为高层配置的参数,且PSCCH的频
域资源限制小于等于一个子信道的大小,且PSCCH位于PSSCH的最低子信道的范围内(如图3所示)。
二、NR SL资源分配方式
NR V2X定义了两种资源分配模式(mode),一种是mode1,即基站调度资源;另一种是mode2,即UE自己决定使用什么资源进行传输,此时资源信息可能来自基站的广播消息或者预配置的信息。UE如果工作在基站范围内并且与基站之间存在无线资源控制(Radio Resource Control,RRC)连接,资源分配模式可以是mode1和/或mode2;UE如果工作在基站范围内但与基站之间不存在RRC连接,资源分配模式只能是mode2;如果UE在基站范围外,那么资源分配模式只能是mode2,例如根据预配置的信息来进行V2X传输。
对于mode 2,具体的工作方式如下:
(1)TX UE在资源选择被触发后,首先确定资源选择窗口,其中,资源选择窗口的下边界在资源选择触发后的T1时间,资源选择窗口的上边界在触发后的T2时间,T2是在传输块(Transport Block,TB)传输的数据包延迟预算(packet delay budget,PDB)内选择的值,且T2不早于T1。
(2)UE在资源选择的之前,需要确定资源选择的备选资源结合集合(candidate resource set),根据资源选择窗口内的资源上测量的参考信号接收功率(Reference Signal Received Power,RSRP)与相应的RSRP门限(threshold)做对比,如果RSRP低于RSRP threhold,那么该资源可以纳入备选资源集合。
(3)资源集合确定后,UE随机在备选资源集合中选择传输资源。其中,UE在本次传输时还可以为接下来的传输预留传输资源。
其中,NR V2X支持链式的资源预留方式,即一个旁链路控制信息(sidelink control information,SCI)可以预留当前的资源,最多可以额外预留两个资源,在下一个资源中,可以再指示两个预留资源。即在资源选择窗口内,可以采用动态预留的方式持续预留资源。
三、往返时间(Round Trip Time,RTT)定位
RTT定位技术是一种用于测距的定位技术。如图4和图5所示,RTT定位过程主要包括如下步骤401至406:
步骤401:启动装置(或者初始化装置)(Initiating Device)向响应装置(Responding Device)发送RTT测量请求。Responding Device接收到RTT测量请求后,准备接收RTT测量信号。
步骤402:Initiating Device向Responding Device发送RTT测量信号。Responding Device测量RTT测量信号,并获得到达时间(Time of Arrival,TOA)测量时刻t1。
步骤403:Responding Device在t2时刻向Initiating Device发送RTT测量信号。
步骤404:Responding Device向Initiating Device发送RX-TX时间差(即t2-t1)。
其中,RX-TX时间差(即t2-t1)也可以在t2时刻在RTT测量信号的负载(payload)中发出。
步骤405.Initiating Device测量Responding Device发送的RTT测量信号,获得TOA测量时刻t3。
步骤406.Initiating Device计算得到RTT=t3-t0-(t2-t1)。其中,如果要估计两个设备之间的距离,只需要把RTT除以2再乘以光速即可。
其中,RTT定位的好处在于:不要求Initiating Device与Responding Device绝对同步。因为,t2与t1只需参考Responding Device的同步源,t3与t0只需要参考Initiating Device的同步源。
另外,两个设备之间的信息交互,设备对RTT测量信号测量所得的结果,可以认为是测量报告的一部分。
四、双边往返时间(Double side RTT)/多RTT(multi-RTT)定位方法
例如图6所示的多RTT过程中,UE1向UE2发送SL PRS1,UE2测量SL PRS1得到第一测量报告,之后UE2向UE1发送SL PRS2,UE1向UE2发送SL PRS3,UE2测量SL PRS3得到第二测量报告,其中,第一测量报告可以和SL PRS2一起发送,也可以和第二测量报告一起发送。
此外,需要说明的是,本申请实施例提供的信息传输方法以及定位参考信号传输方法,可以应用于RTT定位方法中测量报告的传输,也可以应用于其他任意定位方法(例如下行到达时间差(DL Time Difference of Arrival,TDOA)定位,到达角度(Angle of Arrival,AOA)定位,离开角度(Angle of Departual,AoD)定位)中测量报告以及定位参考信号的传输。RTT定位可以包括单边RTT定位,或者多边RTT定位。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的信息传输方法以及定位参考信号传输方法进行详细地说明。
第一方面,参见图7所示,为本申请实施例所提供的一种信息传输方法的流程图,该方法可以包括以下步骤701:
步骤701:第一终端获取传输旁链路测量报告SL MR或物理旁链路共享信道SL PSSCH的第一目标资源池和/或第一目标资源。
其中,所述第一目标资源池和/或第一目标资源,可以是:第一终端自己选择的(具体选择过程会在后文进行叙述);也可以是第二终端(即与第一终端传输信息的终端)选择的;也可以是预定终端(即除第二终端和第一终端之外的其他终端)选择的;也可以是网络侧设备选择的。
另外,第一目标资源池和/或第一目标资源,可以用于第一终端传输SL MR或SL PSSCH,也可以用于第二终端传输SL MR或SL PSSCH。
此外,需要说明的是,SL MR可以是在SL PSSCH信道中传输,其中,SL PSSCH上承载SL MR、SL配置信息、SL定位信息、非SL PRS的定位信息等。因此,SL MR
传输可以认为是SL PSSCH的传输。或者,SL MR可以在PSCCH信道,或者PSFCH信道中传输。
可以理解的是,获取传输SL MR或SL PSSCH的第一目标资源池和/或第一目标资源,即为确定传输SL MR或SL PSSCH的第一目标资源池和/或第一目标资源。
由上述可知,在本申请实施例中,第一终端能够获取传输SL MR或SL PSSCH的第一目标资源池和/或第一目标资源,从而为第一终端传输SL MR或SL PSSCH提供了资源基础,即本申请的实施例,提供了获取传输SL MR或SL PSSCH的第一目标资源池和/或第一目标资源的方法,为实现SL MR或SL PSSCH的传输奠定了基础。因此,本申请实施例提供了实现SL定位中测量报告的传输方法。

即当第一目标资源用于第一终端传输SL MR或SL PSSCH时,第一终端获取到第一目标资源之后,可以在第一目标资源上传输SL MR或SL PSSCH;当第一目标资源用于第二终端传输SL MR或SL PSSCH时,第一终端获取到第一目标资源之后,则需要将获取到的第一目标资源配置或指示给第二终端,以使得第二终端在第一目标资源上传输SL MR或SL PSSCH。

对于A-3项,PSFCH的配置,可以包括RRC在资源池中配置PSFCH的资源。若配置了PSFCH资源,可以认为存在SL MR或SL PSSCH的候选资源,则可以基于PSFCH
配置的时域和/或频域资源位置,选择SL MR或SL PSSCH的资源;或者基于配置了PSFCH的资源的资源池,可以选择SL MR或SL PSSCH的资源池。
对于QoS信息,可以包括优先级,时延预算,功率,信道忙率(Channel Busy Ratio,CBR)等;当满足一定参数条件下,选择对应的资源池或者资源,用于传输SL MR或SL PSSCH。

若待传输数据中存在SL MR或SL PSSCH对应的LCID对应的逻辑信道,则根据资源池的配置选择SL MR或SL PSSCH的资源池;具体的,若配置了SL MR或SL PSSCH的专用资源池,则选择所述专用资源池传输SL MR或SL PSSCH,否则,选择非用于SL PRS和/或非discovery的资源池传输SL MR或SL PSSCH。
另外,在上述第一信息包括SL MR或SL PSSCH的使能信息,或者SL定位使能信息的情况下,根据SL MR或SL PSSCH的使能信息,或者SL定位使能信息,选择第一目标资源池的方法具体如下所述。

可选地,所述第一终端根据第一目标交集或者第一候选资源集合上的检测结果,在第二候选资源集合中,选择传输SL MR或SL PSSCH的所述第一目标资源,包括:
所述第一终端根据所述第一目标交集或者所述第一候选资源集合上的检测结果,排除所述第二候选资源集合中的第二资源,得到第三候选资源集合;

其中,上述第一阈值和/或第二阈值为预定义或预配置或配置或指示的值。
另外,SCI指示或预留的资源(包括SL MR或SL PSSCH的资源和/或SL PRS的资源),存在相应的用途,因此,需要排除第二候选资源集合中SCI指示或预留的资源。
此外,RSRP大于第一阈值,表示表示被其他终端占用的资源上待传输的数据可能大于了第一阈值,如果需要传输SL MR或SL PSSCH的终端还在该被占用的资源上传输,其他终端的数据对该终端的数据传输会造成一定的干扰,因此,当第二候选资源集合中的某一部分资源的RSRP大于第一阈值时,则说明该资源不可用于该终端(即需要传输SL MR或SL PSSCH的终端)的数据的传输,或者认为该资源低优先级用于该终端(即需要传输SL MR或SL PSSCH的终端)的数据传输,因此,可以排除第二候选资源集合中RSRP大于第一阈值的资源。
同理,RSSI大于第二阈值,表示表示该资源上的能量大于了第二阈值,如果需要传输SL MR或SL PSSCH的终端在该资源上传输,那么该资源上的能量会干扰该终端的数据传输,导致该终端在该资源上传输的性能差,因此,当第二候选资源集合中的某一部分资源的RSSI大于第二阈值时,则说明该资源不可用于该终端(即需要传输SL MR或SL PSSCH的终端)的数据的传输,或者认为该资源低优先级用于该终端(需要传输SL MR或SL PSSCH的终端)的数据传输,因此,可以排除第二候选资源集合中RSSI大于第二阈值的资源。

I-2项:所述第一终端选择第二目标交集作为上报给高层的资源集合,所述第二目标交集为所述第三候选资源集合和所述第二候选资源集合的交集。

I-5项:在所述第二目标交集中的资源数目小于所述第一目标资源的资源数目的情况下,所述第一终端从所述第二目标交集,以及所述第三候选资源集合和/或所述第二候选资源集合中,选择上报给高层的资源集合。
进一步,可选地,在所述第二目标交集中的资源数目小于所述第一目标资源的资源数目的情况下,所述第一终端选择所述第二目标交集中的资源,以及所述第二候选资源集合和/或所述第三资源集合中除所述第二目标交集之外的至少部分资源形成的资源集合,作为上报给高层的资源集合。即在第二目标交集中的资源数目小于第一目标资源的资源数目的情况下(即在第二目标交集中的资源数目小于待选择的资源数目的情况下),第一终端可以将第二目标集合,以及第二候选资源集合中除第二目标交集之外的至少部分资源和/或第三候选资源集合中除第二目标交集之外的至少部分资源,上报给高层。

J-3项:所述第一终端从所述第二目标交集和所述第三候选资源集合中,选择所述第一目标资源。
进一步,可选地,所述第一终端选择所述第二目标交集中的资源,以及所述第三候选资源集合中除所述第二目标交集之外的至少部分资源,作为所述第一目标资源。

其中,第二目标交集中的资源数目小于第一目标资源的资源数目,表示第二目标交集中的资源不够选择第一目标资源,因此,此种情况下,可以将第二目标交集中的资源作为第一目标资源的一部分,而第一目标资源的其余部分可以从第二候选资源集合和/或第三候选资源集合中选择。
可选地,所述第一终端获取传输SL MR或SL PSSCH的所述第一目标资源,包括:

可选地,所述第一终端在所述第一目标资源上,传输SL MR或SL PSSCH,包括:
所述第一终端在所述第一目标资源上,并在SCI或MAC CE或PC5-RRC上传输SL MR或SL PSSCH;

可以理解的是,第一终端选择传输SL MR或SL PSSCH的第一目标资源池的方法,可以复用现有SL PSSCH资源选择的流程,也可以采用上述所述的“根据第一信息,选择传输SL MR或SL PSSCH的所述第一目标资源池”的方法。
同理,第一终端选择传输SL MR或SL PSSCH的第一目标资源的方法,可以复用现有的资源选择的流程(例如协议38.214中section 8的SL资源选择流程),也可以采用上述“F-1项或F-2项或F-3项”所述的方法。
其中,当第一终端选择传输SL MR或SL PSSCH的第一目标资源池的方法,采用上述所述的“根据第一信息,选择传输SL MR或SL PSSCH的所述第一目标资源池”的方法时,第一终端则在第一目标资源池中,选择传输SL MR或SL PSSCH的第一目标资源。
第二方面,参见图8所示,为本申请实施例所提供的一种信息传输方法的流程图,该方法可以包括以下步骤801至802:
步骤801:通信设备获取传输旁链路测量报告SL MR或物理旁链路共享信道SL
PSSCH的第一目标资源池和/第一目标资源。
步骤802:所述通信设备将所述第一目标资源池和/或所述第一目标资源配置或指示给第一终端。
其中,所述通信设备为网络侧设备或者第二终端或者预定终端,所述第二终端为与第一终端传输信息的终端。
由此可知,所述第一目标资源池和/或第一目标资源,可以是第二终端(即与第一终端传输信息的终端)选择的;也可以是预定终端(即除第二终端和第一终端之外的其他终端)选择的;也可以是网络侧设备选择的。
其中,第一目标资源池和/或第一目标资源,可以用于第一终端传输SL MR或SL PSSCH,也可以用于第二终端传输SL MR或SL PSSCH。
此外,需要说明的是,SL MR可以是在SL PSSCH信道中传输,其中,SL PSSCH上承载SL MR、SL配置信息、SL定位信息、非SL PRS的定位信息等。因此,SL MR传输可以认为是SL PSSCH的传输。或者,SL MR可以在PSCCH信道,或者PSFCH信道中传输。
可选地,通信设备获取传输SL MR或SL PSSCH的第一目标资源池和/第一目标资源的方法,可以与前述第一方面所述的第一终端选择第一目标资源池和/或第一目标资源的方法相同。可参见前文,此处不再赘述。
综上所述,本申请实施例的旁链路测量报告的传输方法的具体实施方式可如下实施方式一或实施方式二所述:
实施方式一:
