具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE 的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
请参见图1，图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端 设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本申请实施例中并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，或者为位置服务器(例如：E-SMLC或LMF(Location Manager Function))，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是本申请实施例并不限定基站的具体类型和具体通信系统。
新空口(new radio，NR)旁链路(sidelink，SL)资源分配方式有两种，一种基于基站调度(mode 1)，另一种基于终端(User Equipment，UE)自主资源选择(mode 2)。对于基站调度的资源分配方式，UE用于数据传输的sidelink资源由基站决定，并通过下行信令通知发送端(TX)UE；对于UE自主选择的资源分配方式，UE在(预)配置的资源池中选择可用的传输资源，UE在资源选择之前先进行信道监听，根据信道监听结果选择出干扰较小的资源集合，再从资源集合中随机选择用于传输的资源。
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，资源选择窗口的下边界在资源选择触发后的T1时间，资源选择的上边界在触发后的T2时间，其中T2是UE在其传输块(Transport Block，TB)传输的数据时延(packet delay budget，PDB)内选择的值，T2不早于T1。2)UE在资源选择之前，需要确定资源选择的备选资源结合(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 Receiving Power，RSRP)与相应的RSRP门限(threshold)做对比，如果RSRP高于RSRP threhold，那么对该资源进行资源排除，不能纳入备选资源集合。进行资源排除后，资源选择窗口内剩余的资源组成备选资源集合。备选资源集合中的资源在资源选择窗口中的资源的占比要不少于20％，如果少于20％，RSRP threshold需要按照步进值(3dB)进行增加，再进行所述资源排除操作，直到可以选出不少于所述20％的资源。3)备选资源集合确定后，UE随机在备选资源集合中选择传输资源。另外，UE在本次传输可以为接下来的传输预留传输资源。
相关技术中，如图2所示，UE-A(即第一终端)决定一个资源集合，UE-A将资源集合通知给UE-B(即第二终端)，UE-B在进行mode 2资源选择可以考虑UE-A所通知的资源集合。所述资源集合即为一种辅助信息。
在旁链路(Sidelink)传输中，存在以下场景：
场景一：由于半双工的限制，第一终端(RX UE)不能同时收发，第二终端(TX UE)选择的传输资源可能会影响这对UE之间的传输可靠性。
场景二：由于mode 2资源选择的缺陷性，不同TX UE的资源选择会有冲突的可能，辅助信息也可以部分地解决冲突问题。所述缺陷性至少由于mode 2资源选择过程中资源监听的不准确性(例如TX UE和RX UE侧的信道监听结果不一致)和资源选择存在一定随机性造成。
场景三：RX UE收到多个TX UE的物理旁链路控制信道(Physical Sidelink Share Channel，PSSCH)传输，对多个PSSCH传输反馈物理旁链路反馈信道(Physical Sidelink Feedback channel，PSFCH)时，如果PSSCH传输所对应的PSFCH落在相同的PSFCH occasion，由于UE能力和/或功率控制的限制，不能同时发送很多个PSFCH，导致传输可靠性无法保证。
辅助信息可以协调避该问题，但现有技术并未公开如何确定旁链路辅助信息。
