Description

侧行传输方法以及通信装置

技术领域
本申请涉及通信技术领域，尤其涉及一种侧行传输方法以及通信装置。
背景技术
在有些通信系统中，如第五代移动通信系统(5th generation wireless system，5G)中，终端设备与终端设备之间可以通过侧行链路(sidelink)进行信令和数据的传输。这种通过侧行链路来进行传输的方式可以称为侧行传输。用于侧行传输的资源例如可以由终端设备从候选时频资源集合中选择而确定。终端设备针对非周期性的侧行传输，通常基于感知(full sensing)从候选时频资源集合中确定侧行传输资源。然而，基于感知确定候选时频资源集合需要终端设备对资源池内的全部资源进行持续的监听，导致终端设备的功耗较高。
因此，为了降低终端设备的功耗，基于部分感知(partial sensing)确定用于非周期性传输的侧行传输资源受到越来越多的关注。然而，往往由于非周期性传输的数据到达位置具有不确定性，导致终端设备无法对候选时频资源进行充分的感知，影响侧行传输的可靠性。
发明内容
本申请提供一种侧行传输方法以及通信装置，在基于部分感知确定用于非周期性传输的侧行传输资源时，对候选时频资源进行充分感知，提高侧行传输的可靠性。
第一方面，本申请提供了一种侧行传输方法，该方法可以由终端设备执行(如下文示例的第一终端设备)，也可以由配置在终端设备(如第一终端设备)中的部件(如，芯片、芯片系统等)执行，本申请实施例对此不作限定。下文为方便理解，以第一终端设备作为执行主体来说明该方法。
示例性的，该方法包括：第一终端设备根据至少一个第一候选时间单元集合和资源选择窗确定用于非周期性传输的第二候选时间单元集合；其中，该第二候选时间单元集合包括至少一个第一候选时间单元，该第一候选时间单元为该至少一个第一候选时间单元集合中位于该资源选择窗内的一个候选时间单元，该第一候选时间单元与第一时间单元之间的间隔大于或等于M 1个时间单元，M 1为正整数，该第一时间单元为触发资源选择的时间单元，或者该第一时间单元与该触发资源选择的时间单元之间存在时域间隔；该第一终端设备根据该第二候选时间单元集合确定用于传输第一数据包的侧行传输资源。
基于上述方案，第一终端设备可以从第一候选时间单元集合位于资源选择窗内的候选时间单元中确定出用于非周期性传输的第二候选时间单元集合，第二候选时间单元集合中的第一候选时间单元为第一候选时间单元集合位于资源选择窗内的候选时间单元，且第一候选时间单元与第一时间单元之间间隔大于或等于M 1，使得第一终端设备可以在第一时间单元之后，感知大于或者等于M 1个时间单元，以对第二候选时间单元集合中的至少一个第一候选时间单元进行充分感知，提高了非周期性传输的可靠性。
应理解，M 1可以是由基站配置或者预配置的且M 1大于或者等于M' min，该M' min是由基站配置或者预配置的用于非周期传输的最小连续监听时隙数，M' min与用于周期传输的最小连续监听时隙数M min可以相同或者不同；或者M 1就为M' min。
结合第一方面，在一些可能的实现方式中，该第一候选时间单元集合用于第二数据包的周期性传输。
由于第一终端设备针对周期性传输进行的资源感知较为充分，例如，当第一候选时间单元集合用于周期性传输时，第一终端设备可以在第一候选时间单元集合中的候选时间单元对应的感知机会上，对其他终端设备的周期预留进行基于周期的部分感知，并且第一终端设备还可以通过连续部分感知其他终端设备的非周期性预留。因此，当第一候选时间单元集合用于周期传输时，第一终端设备将第一候选时间单元集合位于资源选择窗的一些候选时间单元作为第一候选时间单元，使得第二候选时间单元集合中的第一候选时间单元可以利用周期性传输的资源感知结果，实现了对第二候选时间单元的充分感知，提高了非周期性传输的可靠性。
为了实现第一候选时间单元与第一时间单元之间间隔M 1个时间单元，保证第一候选时间单元能够被充分感知，下面结合第一方面，提供如下两种可能的实现方式：
方式一：该资源选择窗的起始时间单元为第一时间单元，该第一候选时间单元与该资源选择窗的起始时间单元之间的间隔大于或等于该M 1个时间单元。
方式二：该资源选择窗的起始时间单元在该第一时间单元之后，且与该第一时间单元间隔该M 1个时间单元。
其区别在于，在方式一中，第一终端设备沿用资源选择窗的定义，在此基础上确定其中满足与第一时间单元之间间隔大于或等于M 1个时间单元的第一候选时间单元；在方式二中，由于资源选择窗内的时间单元均满足与第一时间单元之间间隔大于或等于M 1个时间单元，第一终端设备在确定第一候选时间单元的过程中，不需要再确定资源选择窗内的时间单元与第一时间单元之间的间隔。
结合第一方面，在一些可能的实现方式中，该第一终端设备根据该第二候选时间单元集合确定用于传输第一数据包的侧行传输资源，包括：该第一终端设备在资源感知窗内对候选时频资源集合的时频资源进行感知，排除被预留的时频资源，得到时频资源集合；该候选时频资源集合为基于该第二候选时间单元集合确定的，该资源感知窗在该第二候选时间单元集合之前，该资源感知窗的第一个时间单元与该第二候选时间单元集合中的第一个时间单元之间间隔M 2个时间单元，M 2大于或等于该M 1，同理，M 2可以是由基站配置或者预配置的且M 2大于或者等于M' min，或者M 2就为M' min，和/或，该资源感知窗的最后一个时间单元与该第二候选时间单元集合中的第一个时间单元之间间隔M 3个时间单元，M 3等于处理时间；该第一终端设备在该时频资源集合中 确定用于传输该第一数据包的侧行传输资源。
通过该实现方式，由于资源感知窗的第一个时间单元与第二候选时间单元集合中的第一个第一候选时间单元之间间隔M 2个时间单元，因此第一终端设备可以在该资源感知窗内对第二候选时间单元集合中的第一候选时间单元进行充分的资源感知。
结合第一方面，在一些可能的实现方式中，该第二候选时间单元集合包括的候选时间单元的数量n小于预设值Y，该第一终端设备从第一资源池中随机选择m个时间单元，m与n之和大于或等于Y。
通过该实现方式，第一终端设备确定的第二候选时间单元集合中的候选时间单元可以满足最小候选时间单元(如下述Y' min)的要求。
结合第一方面，在一些可能的实现方式中，该资源选择窗的最后一个时间单元与该触发资源选择的时间单元之间间隔M 4个时间单元，该M 4等于剩余包时延预算PDB。
通过该实现方式，资源选择窗具有更大的时域范围，也即第一候选时间单元集合中有更多的候选时间单元位于资源选择窗中，此种情况下，第二候选时间单元集合中的第一候选时间单元的数量更多，有利于第一终端设备传输侧行数据时进行资源选择，提高侧行传输的可靠性。
第二方面，本申请提供了一种侧行传输方法，该方法可以由终端设备执行(如下文示例的第一终端设备)，也可以由配置在终端设备(如第一终端设备)中的部件(如，芯片、芯片系统等)执行，本申请实施例对此不作限定。下文为方便理解，以第一终端设备作为执行主体来说明该方法。
示例性的，该方法包括：第一终端设备根据资源选择窗确定用于非周期性传输的第二候选时间单元集合；其中，该第二候选时间单元集合包括至少一个第一候选时间单元，该第一候选时间单元为该资源选择窗内的一个候选时间单元，该第一候选时间单元与第一时间单元之间的间隔大于或等于M 1个时间单元，M 1为正整数，该第一时间单元为触发资源选择的时间单元，或者该第一时间单元与该触发资源选择的时间单元之间存在时域间隔；该第一终端设备根据该第二候选时间单元集合确定用于传输第一数据包的侧行传输资源。
可选的，M 1可以是由基站配置或者预配置的且M 1大于或者等于M' min，该M' min是由基站配置或者预配置的用于非周期传输的最小连续监听时隙数，M' min与用于周期传输的最小连续监听时隙数M min可以相同或者不同；或者M 1就为M' min。
基于上述方案，第一终端设备可以从资源选择窗确定用于非周期传性传输的第二候选时间单元集合，第二候选时间单元集合中的第一候选时间单元为资源选择窗内的时间单元，且第一候选时间单元与第一时间单元之间间隔大于或等于M 1。使得第一终端设备可以在第一时间单元之后，感知大于或者等于M 1个时间单元，以对第二候选时间单元集合中的至少一个第一候选时间单元进行充分感知，提高了非周期性传输的可靠性。
为了实现第一候选时间单元与第一时间单元之间间隔M 1个时间单元，保证第一候选时间单元能够被充分感知，下面结合第二方面，提供如下两种可能的实现方式：
方式一：该资源选择窗的起始时间单元为该第一时间单元，该第一候选时间单元与该资源选择窗的起始时间单元之间的间隔大于或等于该M 1个时间单元。
方式二：该资源选择窗的起始时间单元在该第一时间单元之后，且与该第一时间单元间隔该M 1个时间单元。
其区别在于，在方式一中，第一终端设备沿用资源选择窗的定义，在此基础上确定其中满足与第一时间单元之间间隔大于或等于M 1个时间单元的第一候选时间单元；在方式二中，由于资源选择窗内的时间单元均满足与第一时间单元之间间隔大于或等于M 1个时间单元，第一终端设备在确定第一候选时间单元的过程中，不需要再确定资源选择窗内的时间单元与第一时间单元之间的间隔。
结合第二方面，在一些可能的实现方式中，该第一终端设备根据该第二候选时间单元集合确定用于传输第一数据包的侧行传输资源，包括：
该第一终端设备在资源感知窗内对候选时频资源集合的时频资源进行感知，排除预留的时频资源，得到时频资源集合；该候选时频资源集合为基于该第二候选时间单元集合确定的，该资源感知窗在该第二候选时间单元集合之前，该资源感知窗的第一个时间单元与该第二候选时间单元集合中的第一个时间单元之间间隔M 2个时间单元，M 2大于或等于该M 1，同理，M 2可以是由基站配置或者预配置的且M 2大于或者等于M' min，或者M 2就为M' min，和/或，该资源感知窗的最后一个时间单元与该第二候选时间单元集合中的第一个时间单元之间间隔M 3个时间单元，M 3等于处理时间；该第一终端设备在该时频资源集合中确定用于传输该第一数据包的侧行传输资源。
通过该实现方式，由于资源感知窗的第一个时间单元与第二候选时间单元集合中的第一个第一候选时间单元之间间隔M 2个时间单元，因此第一终端设备可以在该资源感知窗内对第二候选时间单元集合中的第一候选时间单元进行充分的资源感知。
可选的，该第二候选时间单元集合包括的候选时间单元的数量n小于预设值Y，该第一终端设备从第一资源池中随机选择m个时间单元，m与n之和大于或等于Y。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请提供的通信方法可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th Generation，5G)移动通信系统或新无线接入技术(new radio access technology，NR)。其中，5G移动通信系统可以包括非独立组网(non-standalone，NSA)和/或独立组网(standalone，SA)。
本申请提供的通信方法还可以应用于机器类通信(machine type communication，MTC)、机器间通信长期演进技术(Long Term Evolution-machine，LTE-M)、设备到设备(device to device，D2D)网络、机器到机器(machine to machine，M2M)网络、物联网(internet of things，IoT)网络或者其他网络。其中，IoT网络例如可以包括车联网。其中，车联网系统中的通信方式统称为车到其他设备(vehicle to X，V2X，X可以代表任何事物)，例如，该V2X可以包括：车辆到车辆(vehicle to vehicle，V2V)通信，车辆与基础设施(vehicle to infrastructure，V2I)通信、车辆与行人之间的通信(vehicle to pedestrian，V2P)或车辆与网络(vehicle to network，V2N)通信等。
本申请提供的通信方法还可以应用于未来的通信系统，如第六代移动通信系统等。本申请对此不作限定。
本申请实施例中，网络设备可以是任意一种具有无线收发功能的设备。网络设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和分布式单元。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU可以负责处理非实时协议和服务，如，可以实现无线资源控制(radio resource control，RRC)层、业务数据自适应协议(service data adaptation protocol，SDAP)层和/或分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU可以负责可以处理物理层协议和实时服务。例如可以实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。一个DU可以仅连接到一个CU或者连接到多个CU，而一个CU可以连接到多个DU，CU与DU之间可以通过F1接口进行通信。AAU可以实现部分物理层处理功能、射频处理及有源天线的相关功能。由于 RRC层的信息最终会被递交至PHY层从而变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。
可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
网络设备为小区提供服务，终端设备通过网络设备分配的传输资源(例如，频域资源，或者说，频谱资源)与小区进行通信，该小区可以属于宏基站(例如，宏eNB或宏gNB等)，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等，这些小小区具有覆盖范围小、发射功率低等特点，适用于提供高速率的数据传输服务。
在本申请实施例中，终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。
终端设备可以是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例可以为：手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑(如笔记本电脑、掌上电脑等)、移动互联网设备(mobile internet device，MID)、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等。
其中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，终端设备还可以是物联网(Internet of things，IoT)系统中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。IoT技术可以通过例如窄带(narrow band，NB)技术，做到海量连接，深度覆盖，终端省电。
此外，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。
应理解，本申请对于网络设备和终端设备的具体形式均不作限定。
为便于理解本申请实施例，首先结合图1详细说明适用于本申请实施例的通信系统。图1示出了适用于本申请实施例的侧行传输方法的通信系统的示意图。如图1所示，通信系统100可以包括至少一个网络设备和多个终端设备，例如图1中所示的网络设备110、终端设备121至124。网络设备110和各终端设备121至124可分别通过无线空口通信，终端设备之间可以通过车用无线通信技术通信。例如图1中所示的终端设备121与终端设备123之间可以相互通信，终端设备122与终端设备124之间也可以相互通信。
应理解，图1仅为示例，示出了终端设备121向终端设备123发送信令和/或数据，以及终端设备122向终端设备124发送信令和/或数据的场景，但这不应对本申请构成任何限定。终端设备121与终端设备123之间也可以有信令和/或数据的交互，终端设备122与终端设备124之间也可以有信令和/或数据的交互。本申请实施例对此不作限定。
还应理解，图1仅为示例，示出了一个网络设备和四个终端设备。但这不应对本申请构成任何限定。该通信系统100还可以包括更多的网络设备，也可以包括更多或更少的终端设备。本申请实施例对此不作限定。
在图1所示的通信系统中，终端设备之间可通过侧行链路来进行数据和信令的传输。终端设备通过侧行链路通信所使用的资源可以由网络设备分配。换言之，网络设备为侧行传输分配资源。例如，图1中的终端设备121可通过网络设备分配的资源向终端设备123发送信令和/或数据，终端设备122可通过网络设备分配的资源向终端设备124发送信令和/或数据。
网络设备例如可以通过如下列举的两种模式为侧行链路分配资源：
模式(mode)1：网络设备可以调度资源给终端设备进行侧行传输。比如，图1中所示的网络设备110可以分别调度资源给终端设备121和终端设备122进行侧行传输。
模式2：终端设备可以从网络设备预配置的资源中选择资源进行侧行传输。比如，图1中的终端设备121和终端设备122可分别从网络设备预配置的资源中选择资源进行侧行传输。
在模式2中，终端设备对资源的选择可以包括如下三种方式：基于感知(full sensing)的资源选择、基于部分感知(partial sensing)的资源选择和随机选择(random selection)。
其中，基于感知的资源选择可以对资源池内的资源进行持续的监听，也即对资源池内每个时隙上的所有资源进行持续感知。结合图2所示，当第一终端设备的高层在时隙n触发物理层进行资源选择时，物理层会根据感知窗
Figure PCTCN2022124570-appb-000001
内的感知结果，在资源选择窗[n+T 1,n+T 2]内确定用于发送的候选资源集合。采用感知的好处在于能够准确且持续的得到资源池内的资源占用情况，可以精确的确定出用于传输的资源，但是基于感知的资源选择需要终端设备持续监听，导致终端功耗较高。
其中，n为触发资源选择的时隙，T 0为基站配置或者预配置的监听时长
Figure PCTCN2022124570-appb-000002
为终端处理感知结果的处理时间，T 1、T 2的取值取决于终端设备的实现，T 1可以满足0≤T1≤Tproc，Tproc的值可以与侧行链路带宽部分(bandwidth part，BWP)的子载波间隔(subcarrier space，SCS)配置μ SL相关。例如，Tproc与μ SL具有如表1中所示的对应关系。
表1
μ SL T proc[单位：时隙]
0 1
1 1
2 2
3 4
表1中，μ SL为0时，对应15k子载波间隔；μ SL为1时，对应30k子载波间隔；μ SL为2时，对应60k子载波间隔；μ SL为3时，对应120k子载波间隔。
T2可以满足T2min≤T2≤TPDB，TPDB为剩余(remianing)包时延预算(packet delay budget，PDB),T2min是基站配置或者预配置的T2的最小值。
进一步的，终端设备的物理层将候选资源集合上报给高层，比如媒体接入控制(media access control，MAC)层。
相比于感知的资源选择，部分感知和不基于任何感知结果的资源随机选择可以降低终端功耗。对于部分感知，又分为基于周期的部分感知(periodic-based partial sensing，PBPS)和连续部分感知(contiguous partial sensing，CPS)，一般来说，PBPS可以对资源池中其他终端设备为周期性传输预留的资源进行监听，CPS可以对资源池中其他终端设备为非周期性传输预留的资源进行监听。
具体而言，对于PBPS，终端设备会在如图3所示的资源选择窗[n+T 1,n+T 2]内确定一个候选时隙集合Y。为了保证有足够的资源用于选择，候选时隙集合Y需要大于等于Y min，Y min是由基站配置或者预配置的。集合中的每个候选时隙对于资源池上配置的全部或者部分预留周期(Preserve)都会对应1个或者2个感知机会(sensing occasion)，感知机会可以是基站配置或者预配置的，例如图3中候选时隙t y0对应两个预留周期的各两个感知机会，如预留周期为P 1的感知机会t y0-p1和t y0-2p1，以及预留周期为P 2的感知机会t y0-p2和t y0-2p2。
结合图3所示，对于CPS，终端设备需要在第一个候选时隙t y0之前的CPS监听窗中监听至少M min个时隙，M min是由基站配置或者预配置的，以满足终端设备通过足够多个监听时隙，保证监听结果的准确性。
终端设备分别基于上述PBPS中的各感知机会和上述CPS中的CPS监听窗，对候选时频资源集合的时频资源进行监听，以排除被资源池中其他终端设备预留或者占用的时频资源，得到最终的时频资源集合，其中，候选时频资源集合为基于候选时隙集合Y确定的，进而，终端设备的物理层将最终的时频资源集合上报给高层，比如MAC层。
由此可见，终端设备针对周期性传输的业务，可以确定具有充足的候选时隙(即 候选时隙数大于或等于Y min)，且基于上述PBPS和CPS，能够使终端设备对基于候选时隙集合Y确定的候选时频资源集合，进行充分感知(即监听至少M min个时隙)，并在排除已被预留的时频资源后，得到最终的时频资源集合。
然而，对于非周期性传输的业务，由于数据到达的位置无法确定，若使用终端设备针对周期性传输的业务确定的候选时隙集合Y作为非周期性传输的业务的候选时隙集合Y′，无法确保候选时隙集合Y′中的候选时隙均能被充分感知，也即针对候选时隙集合Y′中的候选时隙的监听时间满足最小感知时间的要求(例如监听至少M' min个时隙)，也无法确保候选时隙集合Y′中的候选时隙充足，也即候选时隙集合Y′中的候选时隙的数量满足最小候选时隙数(例如候选时隙数大于或等于Y' min)。
需要说明的是M' min和Y' min为针对非周期性传输的约束参数，二者均可以是基站配置的或者预配置的。M' min和M min可以相同也可以不同，Y' min和Y min可以相同也可以不同。
例如，结合图4所示，终端设备的高层在时隙(slot)m触发了物理层对于传输块(transport block，TB1)的资源选择，TB1为周期性传输(即传输周期Prsvp_TX≠0)，终端设备在第一资源选择窗中选择候选时隙集合Y，如Y中的候选时隙包括t y0，t y1…t yL。紧接着，终端设备的高层在slot n触发了物理层对于TB2的资源选择，TB2为非周期性传输(即传输周期Prsvp_TX＝0))。候选时隙集合Y在slot n之后的第一个候选时隙t y2与第二资源选择窗的起始时隙之间的间隔不满足M' min的要求，并且，由于候选时隙集合Y在在slot n之后剩余的候选时隙过少时，无法满足Y' min的要求。因此，在基于部分感知的资源选择场景中，终端设备如何确定用于非周期性传输的候选时隙集合Y′，以提高非周期性传输的传输可靠性是需要解决的问题。
针对上述问题，本申请实施例中，在终端设备确定的用于非周期性传输的第二候选时间单元集合(如上述候选时隙集合Y′)中，包括至少一个第一候选时间单元，该第一候选时间单元与第一时间单元(例如上述slot n或slot n+T 1)间隔大于或等于M 1(例如上述M' min)个时间单元，使得终端设备可以在第一时间单元之后，感知大于或者等于M 1个时间单元，以对候选时间单元集合Y′中的至少一个第一候选时间单元进行充分感知，提高了非周期性传输的可靠性。
进一步地，在本申请实施例的一些示例中，在第一候选时间单元的数量不能满足Y' min的要求时，终端设备可以对第二候选时间单元集合中的候选时间单元进行补充，例如通过随机选择从第一资源池中确定候选时间单元或者从第一候选时间单元集合(如上述候选时隙集合Y)确定优先级较低的候选时间单元(下文中进行详细说明)，使第二候选时间单元集合中的候选时间单元满足Y' min的要求，进一步提高非周期性传输的可靠性。
为便于理解本申请实施例，首先对本申请中涉及到的术语作简单说明。
1、时间单元：比如可以是时隙(slot)、子帧(sub frame)、符号(symbol)、或者其他未来定义的时间单元。需注意，时间单元是时域的一种计量单位，并不一定是最小的时间单元。
在NR中，时隙为调度单元。下文中将以时隙作为时间单元的一例来描述本申请实 施例所提供的方法。可以理解的是，下文实施例中涉及时隙的描述也可以替换为其他的时间单元，如子帧、符号等。本申请实施例对此不作限定。
2、资源池(resource pool)、候选(candidate)时频资源集合、时频资源集合：资源池是网络设备预先分配给终端设备使用的资源的集合。该资源池可以是为多个终端设备配置的，该多个终端设备可以基于资源感知、部分资源感知或随机选择的方式从该资源池中选择资源，以用于侧行传输。
候选时频资源集合是由终端设备从资源池中确定的可用于侧行传输的候选资源的集合，该候选时频资源集在时域上可以通过候选时间单元集合表述，也即候选时间单元集合中的候选时间单元为候选时频资源集合的时域约束，候选时频资源集合在频域上可以等于上述资源池的频域范围，具体地，在每个候选时隙对应频域范围中，每L subCH个连续的子信道(sub channel)可以作为一个候选资源，所有候选时隙时域和频域范围内对应的候选资源组成候选资源集合。该L subCH是由终端高层通知给该终端的物理层。
本申请实施例中，上述候选时间单元集合包括用于周期性传输的候选时间单元集合(同第一候选时间单元集合)和用于非周期性传输的候选时间单元集合(同第二候选时间单元集合)。
其中，用于周期性传输的候选时间单元集合是由终端设备从该周期性传输的触发资源选择的时间单元对应的资源选择窗中确定的，假设该周期性传输的触发资源选择的时间单元为m，资源选择窗例如可以是[m+T 1,m+T 2]。
用于非周期性传输的候选时间单元集合是由终端设备从该非周期性传输的触发资源选择的时间单元对应的资源选择窗中确定的。具体而言，用于非周期性传输的候选时间单元集合可以是后文结合图5所描述的方法200中根据至少一个第一候选时间单元集合和资源选择窗确定的候选时间单元集合，也可以是后文结合图8所描述的方法300中根据资源选择窗确定的候选时间单元集合。该非周期性传输的触发资源选择的时间单元对应的资源选择窗可以是后文结合图5所描述的方法200或图8所描述的方法300中描述的任一资源选择窗。
时频资源集合是由终端设备基于资源感知结果从资源池确定的可用于侧行传输的资源。在本申请实施例中，该时频资源集合可以是从候选时频资源集合中确定的资源。换言之，时频资源集合是候选时频资源集的子集。
在一种实现方式中，终端设备的物理层可以对候选时频资源集合(如后文实施例中的基于第二候选时间单元集合确定的候选时频资源集合)中确定时频资源集合，并将该时频资源集合上报给高层，比如MAC层。MAC层可以进一步从该时频资源集合中选择用于侧行传输的资源。随后，MAC层可以将选择的资源指示给物理层，物理层进而通过该资源进行侧行传输。
还应理解的是，上述候选时频资源集合也称作初始候选时频资源集合，上述时频资源集合也称作候选时频资源集合。
为便于理解本申请实施例，做出如下几点说明。
第一，在下文示出的实施例中，第一、第二以及各种数字编号仅为描述方便进行的区分，并不用来限制本申请实施例的范围。例如，区分不同的时间单元、不同的候 选时间单元集合等。
第二，“预定义”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
“预配置”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，也可以通过信令预配置，比如网络设备通过信令预配置等方式来实现，本申请对于其具体的实现方式不做限定。
其中，“保存”可以是指，保存在一个或者多个存储器中。所述一个或者多个存储器可以是单独的设置，也可以是集成在编码器或者译码器，处理器、或通信装置中。所述一个或者多个存储器也可以是一部分单独设置，一部分集成在译码器、处理器、或通信装置中。存储器的类型可以是任意形式的存储介质，本申请并不对此限定。
第三，本申请实施例中涉及的“协议”可以是指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议，本申请对此不做限定。
第四，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。
第五，在本申请实施例中，“当……时”、“在……的情况下”、“若”以及“如果”等描述均指在某种客观情况下设备(如，终端设备或者网络设备)会做出相应的处理，并非是限定时间，且也不要求设备(如，终端设备或者网络设备)在实现时一定要有判断的动作，也不意味着存在其它限定。
第六，本申请实施例中第一终端设备确定传输数据包的侧行传输资源，也即从候选时频资源集合中选择用于传输数据包的侧行传输资源。下文中“确定”和“选择”交替使用，其所表达的含义是相同的。
下面将结合附图对本申请实施例提供的侧行传输方法做详细说明。
应理解，下文仅为便于理解和说明，以执行主体为第一终端设备为例进行说明，本申请实施例中第一终端设备可以向其他设备(例如第二终端设备)传输侧行数据，例如当第一终端设备为图1中的终端设备121时，第二终端设备可以是图1中的终端设备123，或者，第一终端设备可以是图1中的终端设备122时，第二终端设备可以是图1中的终端设备124。
但应理解，这不应对本申请提供的方法的执行主体构成任何限定。只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法，便可以作为本申请实施例提供的方法的执行主体。例如，下文实施例所示的第一终端设备也可以替换为该第一终端设备中的部件，比如芯片、芯片系统或其他能够调用程序并执行程序的功能模块。
图5为本申请实施例提供的一种侧行传输方法200的示意性流程图。如图2所示，该方法200可以包括S210和S220。下面对方法200中的各个步骤做详细说明。
S210，第一终端设备根据至少一个第一候选时间单元集合和资源选择窗确定用于非周期性传输的第二候选时间单元集合。
该第二候选时间单元集合包括至少一个第一候选时间单元，该第一候选时间单元为至少一个第一候选时间单元集合中位于资源选择窗内的一个候选时间单元，该第一候选时间单元与第一时间单元之间的间隔大于或等于M 1个时间单元，M 1为正整数，该第一时间单元为所述触发资源选择的时间单元，或者该第一时间单元与触发资源选择的时间单元之间存在时域间隔；
S220，第一终端设备根据该第二候选时间单元集合确定用于传输第一数据包的侧行传输资源。
需要说明的是，第一候选时间单元集合可以用于第二数据包的周期性传输，该第一候选时间单元集合例如可以是前述示例中的候选时隙集合Y。但这不应理解为对本申请的限定，例如第一候选时间单元集合还可以是用于非周期性传输的候选时间单元集合。其中，第二数据包可以包括侧行传输的信令和/或数据，例如第二数据包可以是TB(例如前述TB1)，本申请实施例对第二数据包的具体内容不做限定。
以第一候选时间单元集合用于第二数据包的周期性传输为例，在资源池内使能周期性传输时，第一终端设备可以选择资源池的任一预留周期进行第二数据包的周期性传输，当第一终端设备需要发送多个周期性传输的数据包时，可以为每个周期性传输分别选择预留周期，且各周期性传输选择的预留周期可以相同也可以不同。
进一步的，第一终端设备可以针对每个周期性传输，确定一个第一候选时间单元集合，使得第一终端设备可以在部分感知场景中，如前所述的基于PBPS对其他终端设备在资源池内的周期性预留进行感知，还可以基于CPS对其他终端设备的非周期性预留进行感知。
在上述S210中，为了使用于非周期性传输的候选时间单元能够被充分感知，第一终端设备确定的第二候选时间单元集合中的至少一个第一候选时间单元，应与第一时间单元之间间隔大于或等于M 1个时间单元。
其中，M 1可以是预定义的、预配置的或者协议定义的。例如，M 1可以是预先保存在第一终端设备中的，或者M 1可以是网络设备向第一终端设备发送信令进行预配置的，或者M 1可以是协议中定义的，如NR协议等。可选的，M 1可以是上述M' min，或者大于上述M' min，M' min是用于非周期传输的最小连续监听时隙数。
在第一候选时间单元与第一时间单元之间的间隔大于或等于M 1个时间单元的基础上，还应理解的是，本申请实施例中的第一候选时间单元是至少一个第一候选时间单元集合中位于资源选择窗内的一个时间单元。换言之，第一终端设备从第一候选时间单元集合中位于资源选择窗内的候选时间单元中，确定其中满足与第一时间单元之间间隔大于或等于M 1个时间单元的候选时间单元，将其确定为第一候选时间单元。
需要说明的是，第一时间单元与触发资源选择的时间单元相关，例如第一时间单元可以是触发资源选择的时间单元(T 1＝0)，如上述slot n，或者第一时间单元可以与触发资源选择的时间单元间隔T 1个时间单元。前已述及，T 1可以满足0≤T 1≤T proc，且T proc的值可以与BWP的SCS配置μ SL相关。将n+T 1作为第一时间单元相比于将n作为第一时间单元的可以为终端提供额外的处理时间用于感知前的准备。第一时间单元与第一候选时间单元集合不相关，不应理解为第一时间单元是第一候选时间单元集合中的候选时间单元，但第一时间单元可以与第一候选时间单元集合中的候选时间单元 具有相同的时域位置。
上述S210中，为了使第一候选时间单元和第一时间单元之间的间隔大于或等于M 1个时间单元，至少可以包括以下两种可能的实现方式：
方式一、资源选择窗的起始时间单元为上述第一时间单元，第二候选时间单元集合的第一个第一候选时间单元与资源选择窗的起始时间单元之间的间隔大于或等于M 1个时间单元。此种情况下，第一终端设备从至少一个第一候选时间单元集合中位于资源选择窗内的候选时间单元中确定第一候选时间单元，该第一候选时间单元包含于第二候选时间单元集合。
结合图6a所示，在slot m触发资源选择的第一候选时间单元集合，其包括的候选时间单元包括t y0、t y1至t yL，当第一终端设备的高层在slot n触发物理层进行非周期性传输的资源选择时，资源选择窗为[n+T 1,n+T 2]的一段时域，其中，第一候选时间单元集合中的t y2至t yL位于该资源选择窗内，并且t y3t yL与资源选择窗的起始时间单元之间的间隔均大于或等于M 1个时间单元，则第一终端设备确定t y3至t yL均为第一候选时间单元，且t y3至t yL包含于第二候选时间单元集合。
方式二、资源选择窗的起始时间单元在第一时间单元之后，且与第一时间单元间隔M 1个时间单元。此种情况下，第一终端设备确定至少一个第一候选时间单元集合中位于资源选择窗内的候选时间单元均为第一候选时间单元，该第一候选时间单元包含于第二候选时间单元集合。
结合图6b所示，在slot m触发资源选择的第一候选时间单元集合，其包括的候选时间单元包括t y0、t y1至t yL，当第一终端设备的高层在slot n触发物理层进行非周期性传输的资源选择时，资源选择窗为[n+T 1+M 1,n+T 2]的一段时域，其中，第一候选时间单元集合中的t y3至t yL位于该资源选择窗内，由于t y3至t yL与第一时间单元之间的间隔均大于或等于M 1个时间单元，则第一终端设备确定t y3至t yL均为第一候选时间单元，且t y3至t yL包含于第二候选时间单元集合。
基于上述方式一或方式二，第一终端设备均可以从第一候选时间单元集合中位于资源选择窗内的时间单元中确定出能够被充分感知的第一候选时间单元，也即第一终端设备确定的第一候选时间单元可以满足即M 1个时间单元的要求。
上述方式一和方式二仅以一个第一候选时间单元集合为例进行了说明，下面针对存在多个第一候选时间单元集合的场景，对上述两种实现方式进行说明。
例如，至少一个第一候选时间单元集合包括第一候选时间单元集合Y 1和第一候选时间单元集合Y 2。
结合图7所示，第一候选时间单元集合Y 1用于为slot m触发的资源选择提供候选时间单元，第一候选时间单元集合Y 1中的时间单元包括t y(1,0)、t y(1,1)至t y(1,L)；第二候选时间单元集合Y 2为slot i触发的资源选择提供候选时间单元，第二候选时间单元集合Y 2中的时间单元包括t y(2,0)、t y(2,1)至t y(2,P)。
针对于上述方式一、本实施例中的资源选择窗可以为图7中的资源选择窗1，即资源选择窗的起始时间单元为第一时间单元，第二候选时间单元集合的第一个第一候选时间单元与资源选择窗的起始时间单元之间的间隔大于或等于M 1个时间单元。
结合图7所示，当第一终端设备的高层在slot n触发物理层进行非周期性传输的资源选择时，资源选择窗为[n+T 1,n+T 2]的一段时域。其中，第一候选时间单元集合Y 1中的t y(1,2)至t y(1,L)位于该资源选择窗内，并且t y(1,L-1)和t y(1,L)与资源选择窗的起始时间单元之间的间隔大于或等于M 1个时间单元，则第一终端设备确定t y(1,L-1)和t y(1,L)为第一候选时间单元，其中t y(1,L-1)对应第二候选资源集合中的t y2'，t y(1,L)对应第二候选资源集合中的t y3'；第一候选时间单元集合Y 2中的t y(2,0)至t y(2,P-1)位于该资源选择窗内，并且t y(2,1)至t y(2,P-1)与资源选择窗的起始时间单元之间的间隔均大于或等于M 1个时间单元，则第一终端设备确定t y(2,1)至t y(2,P-1)为第一候选时间单元，其中，t y(2,1)对应第二候选资源集合中的t y0'，t y(2,2)对应第二候选资源集合中的t y1'，t y(2,3)对应第二候选资源集合中的t y3'，t y(2,P-1)对应第二候选资源集合中的t yL'。
针对于上述方式二、本实施例中的资源选择窗可以为图7中的资源选择窗2，即资源选择窗的起始时间单元在第一时间单元之后，且与第一时间单元间隔M 1个时间单元。此种情况下，第一终端设备确定第一候选时间单元集合Y 1和Y 2中位于资源选择窗内的候选时间单元均为第一候选时间单元。
结合图7所示，当第一终端设备的高层在slot n触发物理层进行非周期性传输的资源选择时，资源选择窗为[n+T 1+M 1,n+T 2]的一段时域，其中，第一候选时间单元集合中Y 1的t y(1,L-1)和t y(1,L)位于该资源选择窗内，由于t y(1,L-1)和t y(1,L)与第一时间单元之间的间隔均大于或等于M 1个时间单元，则第一终端设备确定t y(1,L-1)和t y(1,L)均为第一候选时间单元，其中t y(1,L-1)对应第二候选资源集合中的t y2'，t y(1,L)对应第二候选资源集合中的t y3'；第一候选时间单元集合Y 2中的t y(2,1)至t y(2,P-1)位于该资源选择窗内，并且t y(2,1)至t y(2,P-1)与资源选择窗的起始时间单元之间的间隔均大于或等于M 1个时间单元，则第一终端设备确定t y(2,1)至t y(2,P-1)为第一候选时间单元，其中，t y(2,1)对应第二候选资源集合中的t y0'，t y(2,2)对应第二候选资源集合中的t y1'，t y(2,3)对应第二候选资源集合中的t y3'，
t y(2,P-1)对应第二候选资源集合中的t yL'。
需要说明的是，若第一候选时间单元集合Y 1和Y 2包括相同的候选时间单元，如时间单元t y(1,L)和t y(2,3)，第一候选时间单元集合Y 1和Y 2均对应第二候选时间单元集合中的第一候选时间单元t y3'。
还应理解的是，第一候选时间单元集合Y 1中的候选时间单元t y(1,3)和t y(1,L-1)之间还可以包括其他候选时间单元，且t y(1,3)和t y(1,L-1)之间的候选时间单元在满足与第一时间单元之间的间隔大于或等于M 1时，第一终端设备也将其确定为第一候选时间单元，与此类似的，第一候选时间单元集合Y 2中的t y(2,3)和t y(2,P-1)之间还可以包括其他候选时间单元，这些时间单元与第一时间单元之间的间隔也大于或等于M 1，第一终端设备也将其确定为第一候选时间单元。
在一些实施例中，为了确保第二候选时间单元集合中具有充足的候选时间单元，第一终端设备确定的第二候选时间单元集合中的候选时间单元的数量需要大于或等于预设值Y。
应理解，预设值Y可以是预定义的、预配置的或者协议定义的。例如，Y可以是预先保存在第一终端设备中的，或者Y可以是网络设备向第一终端设备发送信令进行预配置的，或者Y可以是协议中定义的，如NR协议等。可选的，Y可以是上述Y' min，或者大于上述Y' min，Y' min是最小的候选时隙个数。
作为一种示例，当第二候选时间单元集合中的至少一个第一候选时间单元的数量小于预设值Y时，第一终端设备可以从至少一个第一候选时间单元集合中确定至少一个第二候选时间单元，用于补充第二候选时间单元集合中的候选时间单元。
第二候选时间单元例如可以属于资源选择窗和至少一个第一候选时间单元集合的，并且第二候选时间单元与第一时间单元之间的间隔小于M 1个时间单元。
以图6a和图7为例，在图6a中，时间单元t y2属于第一候选时间单元集合，也在资源选择窗内，并且，时间单元t y2与第一时间单元之间的间隔小于M 1个时间单元，则时间单元t y2为第二候选时间单元；在图7中，第一候选时间单元集合Y 1中的时间单元t y(1,2)和t y(1,3)、第一候选时间单元集合Y 2中时间单元t y(2,0)均位于资源选择窗内，并且时间单元t y(1,2)、t y(1,3)和t y(2,0)与第一时间单元之间的间隔均小于M 1个时间单元，则时间单元t y(1,2)、t y(1,3)和t y(2,0)均为第二候选时间单元。
需要说明的是，若第一候选时间单元集合Y 1和Y 2包括相同的候选时间单元，如时间单元t y(1,3)和t y(2,0)，第一候选时间单元集合Y 1和Y 2在第二候选时间单元集合中对应同一个第二候选时间单元。
假设第二候选时间单元集合中的至少一个第一候选时间单元的数量为n个，第二候选时间单元集合中包括的至少一个第二候选时间单元的数量w可以等于Y-n，或者大于Y-n。例如，在w需要等于Y-n时，若第一终端设备确定的第二候选时间单元的数量w'大于所需的第二候选时间单元的数量w，则第一终端设备从w'个第二候选时间单元中确定w个第二候选时间单元。例如，在图7中，第一候选时间单元集合Y 1中的时间单元t y(1,2)和t y(1,3)均可以是第二候选时间单元，在第二候选时间单元集合中仅包括一个第二候选时间单元时，第一终端设备可以将与第一时间单元距离更远的t y(1,3)确定为第二候选时间单元集合中的第二候选时间单元。再例如，在w需要等于Y-n时，若第一终端设备确定的第二候选时间单元的数量w'小于所需的第二候选时间单元的数量w，则第一终端设备可以从第一资源池随机选择w-w'个时间单元，从第一资源池随机选择w-w'个时间单元可以确定为第二候选时间单元，或者确定为第二候选时间单元集合中的第三候选时间单元。
可选的，第一资源池可以是特殊资源池(exceptional resource pool)，一般来说，该特殊资源池是网络设备预配置的，用于在终端设备没有足够的资源感知结果时使用的资源池。
在一些实施例中，若第一候选时间单元集合位于资源选择窗内的时间单元中，满足与第一时间单元间隔大于或等于M 1的候选时间单元的数量大于预设值Y，则可以将这些候选时间单元中的全部或者部分确定为第二候选时间单元集合中的第一候选时间单元。
需要说明的是，第二候选时间单元集合中的第二候选时间单元的优先级低于第一候选时间单元。例如，第一终端设备优先使用第二候选时间单元集合中的第一候选时间单元上的资源进行侧行传输，在第一候选时间单元被预留或者被占用时使用第二候选时间单元集合中的第二候选时间单元上的资源进行侧行传输。
可选的，至少一个第一候选时间单元和至少一个第二候选时间单元可以分别作为独立的候选时间单元集合。
可选的，第三候选时间单元的优先级可以高于第二候选时间单元的优先级或者低于第二候选时间单元的优先级，本申请实施例对此不作限定。
作为另一种示例，当第二候选时间单元集合中的至少一个第一候选时间单元的数量小于预设值Y时，假设至少一个第一候选时间单元的数量为n，第一终端设备可以从第一资源池中随机选择m个时间单元，实现对第二候选时间单元集合中候选时间单元的补充。其中，m与n之和大于或等于Y。
在上述任一实施例中，资源选择窗的最后一个时间单元均以n+T 2为例，应理解的是，本申请实施例中资源选择窗的最后一个时间单元还可以是n+M 4，其中，M 4等于remaining PDB。例如，图6a所示实施例中的资源选择窗和图7所示实施例中的资源选择窗1，均可以是[n+T 1,n+remainingPDB]，在图6b所示实施例中的资源选择窗和图7所示实施例中的资源选择窗2，均可以是[n+T 1+M 1,n+remainingPDB]。
需要说明的是，如前所述，remaining PDB为T 2的最大值，当资源选择窗的最后一个时间单元为n+M 4时，资源选择窗具有更大的时域范围，也即第一候选时间单元集合中有更多的候选时间单元位于资源选择窗中，此种情况下，第二候选时间单元集合中的第一候选时间单元的数量更多，有利于第一终端设备传输侧行数据时进行资源选择，提高侧行传输的可靠性。
针对上述S220需要说明的是：
前已述及，第二候选时间单元集合可以是对候选时频资源集合的时域表征或约束。例如，第一终端设备可以根据第一候选时间单元集合和预设的子信道数，确定候选时频资源集合。
示例性的，第一终端设备可以在资源感知窗内对候选时频资源集合的时频资源进行感知，排除被预留的时频资源，得到时频资源集合，进一步地，第一终端设备在时频资源集合中确定用于传输第一数据包的侧行传输资源。其中，第一数据包可以包括侧行传输的信令和/或数据，本申请实施例对第一数据包的具体内容不做限定。
示例性的，第一终端设备可以在资源感知窗内获取其他终端设备发送的侧行控制信息(sidelink control information，SCI)，第一终端设备可以根据获取到的SCI确定对应的终端设备是否预留了候选时频资源集合中的时频资源。
需要说明的是，为了使候选时频资源集合中的时频资源进行充分的感知，本实施例中的资源感知窗在第二候选时间单元集合之前，且资源感知窗的第一个时间单元与第二候选时间单元集合中的第一个时间单元之间间隔M 2个时间单元，M 2大于或等于M 1，和/或，资源感知窗的最后一个时间单元与第二候选时间单元集合中的第一个时间单元之间间隔M 3个时间单元，M 3等于处理时间。
可选的，处理时间例如可以是T proc,0和T proc,1之和。T proc,0和T proc,1是协议定义的，且 与子载波间隔SCS有关的时隙个数，例如T proc,0与μ SL具有如下表2中所示的对应关系，T proc,1与μ SL具有如下表3所示的对应关系。T proc,0是终端处理感知结果时间，T proc,1是终端资源选择和/或数据准备的时间。

表3

示例性的，表2和表3中，μ SL为0时，对应15k子载波间隔；μ SL为1时，对应30k子载波间隔；μ SL为2时，对应60k子载波间隔；μ SL为3时，对应120k子载波间隔。
例如，结合图6a所示，资源感知窗为[t y0'-M 2,t y0'-M 3]，第一终端设备基于该资源感知窗，可以对t y3至t yL上的候选时频资源集合进行感知。图6b和图7中的资源感知窗与之具有相同或相似的实现方式，此处不再赘述。
在一些实施例中，资源池可以使能资源的重评估和/或抢占评估以提高资源的可靠性。
因此，本申请实施例中，第一终端设备从第一候选时间单元集合位于资源选择窗内的候选时间单元中确定出用于非周期性传输的第二候选时间单元集合，该第二候选时间单元集合中的至少一个第一候选时间单元与第一时间单元之间均间隔大于或等于M 1个时间单元，使得第一终端设备可以在第一时间单元之后，感知大于或者等于M 1个时间单元，以对第二候选时间单元集合中的至少一个第一候选时间单元进行充分感知，提高了非周期性传输的可靠性。
在图5所示实施例以及其相关实现方式中，均假设资源池内使能有周期性传输。当资源池内未使能周期性传输时，资源池内不存在周期预留，那么在部分感知场景下，第一终端设备仅需要进行CPS，不需要进行PBPS。并且，第一终端设备自身也不进行周期性传输，即不存在第一候选时间单元集合。此种情况下，本申请实施例提供如下图8所示实施例以及相关实现方式，对如何确定用于非周期性传输的第二候选时间单 元集合进行说明。
图8为本申请实施例提供的一种侧行传输方法300的示意性流程图。如图8所示，该方法300可以包括S310和S320。下面对方法300中的各个步骤做详细说明。
S310，第一终端设备根据资源选择窗确定用于非周期性传输的第二候选时间单元集合；
其中，该第二候选时间单元集合包括至少一个第一候选时间单元，该第一候选时间单元为该资源选择窗内的时间单元，该第一候选时间单元与第一时间单元之间的间隔大于或等于M 1个时间单元，M 1为正整数，该第一时间单元为触发资源选择的时间单元，或者该第一时间单元与触发资源选择的时间单元之间存在时域间隔；
S320，第一终端设备根据所第二候选时间单元集合确定用于传输第一数据包的侧行传输资源。
与图5所示实施例类似的，在上述S210中，为了使用于非周期性传输的候选时间单元能够被充分感知，第一终端设备确定的第二候选时间单元集合中的至少一个第一候选时间单元，应与第一时间单元之间间隔均大于或等于M 1个时间单元。
其中，M 1可以是预定义的、预配置的或者协议定义的。例如，M 1可以是预先保存在第一终端设备中的，或者M 1可以是网络设备向第一终端设备发送信令进行预配置的，或者M 1可以是协议中定义的，如NR协议等。可选的，M 1可以是上述M' min，或者大于上述M' min，M' min是用于非周期传输的最小连续监听时隙数。
第一时间单元在与图5所示实施例已经说明，此处不再赘述。
需要说明的是，资源选择窗内的时间单元可以是连续的时间单元，例如连续的时隙，也可以是不连续的时间单元，本申请对此不做限定。
上述S310中，为了使第一候选时间单元和第一时间单元之间的间隔大于或等于M 1个时间单元，至少可以包括以下两种可能的实现方式：
方式一、资源选择窗的起始时间单元为上述第一时间单元，第二候选时间单元集合的第一个第一候选时间单元与资源选择窗的起始时间单元之间的间隔大于或等于M 1个时间单元。此种情况下，第一终端设备从资源选择窗内的时间单元中确定第一候选时间单元，该第一候选时间单元包含于第二候选时间单元集合。
结合图9a所示，当第一终端设备的高层在slot n触发物理层进行非周期性传输的资源选择时，资源选择窗为[n+T 1,n+T 2]的一段时域，第一终端设备可以将资源选择窗内位于n+T 1+M 1之后的时间单元(如t y0'至t yL')确定为第一候选时间单元，且t y0'至t yL'包含于第二候选时间单元集合。
方式二、资源选择窗的起始时间单元在第一时间单元之后，且与第一时间单元间隔M 1个时间单元。此种情况下，第一终端设备确定资源选择窗内的时间单元均为第一候选时间单元，在一些实施例中，第一终端设备也可以确定资源选择窗内的部分时间单元为第一候选时间单元，该第一候选时间单元包含于第二候选时间单元集合。
结合图9b所示，当第一终端设备的高层在slot n触发物理层非周期性传输的资源选择时，资源选择窗为[n+T 1+M 1,n+T 2]的一段时域，第一终端设备可以将资源选择窗内的全部时间单元(如t y0'至t yL')确定为第一候选时间单元，且t y0'至t yL'包含于第二候 选时间单元集合。
基于上述方式一或方式二，第一终端设备均可以从资源选择窗内的时间单元中确定出能够被充分感知的第一候选时间单元，也即第一终端设备确定的第一候选时间单元可以满足M 1个时间单元的要求。
在一些实施例中，当第二候选时间单元集合中的至少一个第一候选时间单元的数量小于预设值Y时，假设至少一个第一候选时间单元的数量为n，第一终端设备可以从第一资源池中随机选择m个时间单元，实现对第二候选时间单元集合中候选时间单元的补充。其中，m与n之和大于或等于Y。
可选的，该第一资源池可以是上述特殊资源池。
可选的，第一终端设备可以将从第一资源池中随机选择的候选时间单元作为优先级较低的候选时间单元。例如，第一终端设备优先使用第二候选时间单元集合中的第一候选时间单元上的资源进行侧行传输，在第一候选时间单元被预留或者被占用时使用第二候选时间单元集合中的第二候选时间单元上的资源进行侧行传输。
可选的，至少一个第一候选时间单元和至少一个第二候选时间单元可以分别作为独立的候选时间单元集合。
与图5所示实施例类似的，本实施例中的资源选择窗的最后一个时间单元均以n+T 2为例，应理解的是，本实施例中资源选择窗的最后一个时间单元还可以是n+M 4，其中，M 4等于remaining PDB。例如，图9a所示实施例中的资源选择窗可以是[n+T 1,n+remainingPDB]，在图9b所示实施例中的资源选择窗可以是[n+T 1+M 1,n+remainingPDB]。
其要实现的技术效果与图5所示实施例相同或者相似，此处不再赘述。
在上述S320中，通常通过第一终端设备在资源感知窗内对候选时频资源集合中的时频资源进行感知，排除其他终端设备预留的时频资源，得到时频资源集合，并在该时频资源集合中确定用于传输第一数据包的侧行传输资源。然而为了提高感知结果的可靠性，本申请实施例中的资源感知窗在第二候选时间单元集合之前，且资源感知窗的第一个时间单元与第二候选时间单元集合中的第一个时间单元之间间隔M 2个时间单元，M 2大于或等于M 1，和/或，资源感知窗的最后一个时间单元与第二候选时间单元集合中的第一个时间单元之间间隔M 3个时间单元，M 3等于处理时间。
可选的，处理时间例如可以是T proc,0和T proc,1之和。T proc,0和T proc,1是与协议定义的，且与子载波间隔SCS有关的时隙个数。T proc,0是终端处理感知结果时间，T proc,1是终端资源选择和/或数据准备的时间。
例如，结合图9a所示，资源感知窗为[t y0'-M 2,t y0'-M 3]，第一终端设备基于该资源感知窗，可以对t y0'至t yL'上的候选时频资源集合进行感知。图9b中的资源感知窗与之具有相同或相似的实现方式，此处不再赘述。
上述S320中的相关实现方式均可以参见图5所示实施例中的S220，二者具有相同或者相似的实现方式，此处不再赘述。
因此，本申请实施例中，第一终端设备从资源选择窗确定的用于非周期性传输的第二候选时间单元集合，包括至少一个第一候选时间单元，且该第一候选时间单元与 第一时间单元间隔大于或等于M 1个时间单元，使得第一终端设备可以在第一时间单元之后，感知大于或者等于M 1个时间单元，以对第二候选时间单元集合中的至少一个第一候选时间单元进行充分感知，提高了非周期性传输的可靠性。
本申请实施例还提供一种可能的实现方式，以实现确定用于非周期性传输的第二候选时间单元集合。在如下S410至S470中，tyi为至少一个第一候选时间单元集合中位于资源选择窗的任意一个时间单元：
S410，第一终端设备确定tyi是否为至少一个第一候选时间单元集合中的第一个候选时间单元ty0。
若tyi为ty0，则执行S420，若tyi不为ty0，则执行S430。
S420，第一终端设备确定第二候选时间单元集合包括该至少一个第一候选时间单元集合中的全部候选时间单元(例如ty0至tyL)，也即至少一个第一候选时间单元集合等于第二候选时间单元集合。
需要说明的是，至少一个第一候选时间单元集合中的第一个候选时间单元ty0位于资源选择窗中的情况下，第二候选时间单元集合与至少一个第一候选时间单元集合相等，第二候选时间单元可以利用至少一个第一候选时间单元集合的CPS感知结果，提高资源感知的准确性。
S430，第一终端设备确定第二候选时间单元集合中的位于资源选择窗内的时间单元tyi是否有对应的重评估/抢占评估的感知结果。
若tyi有对应的重评估/抢占评估的感知结果，则执行S440，否则执行S450。
S440，第一终端设备确定第二候选时间单元集合包括该至少一个第一候选时间单元集合中从时间单元tyi开始的全部时间单元。
此种情况下，第二候选时间单元集合可以利用tyi的重评估/抢占评估的感知结果。
S450，第一终端设备确定tyi与第一时间单元之间的间隔是否大于或者等于M 1。
若tyi与第一时间单元之间的间隔是否大于或者等于M 1，则执行S460，否则执行S470。
S460，第一终端设备确定第二候选时间单元集合包括该至少一个第一候选时间单元集合中从时间单元tyi开始的全部时间单元。
此种情况下，第二候选时间单元中的每个候选时间单元均与第一时间单元间隔大于或者等于M 1个时间单元。
S470，第一终端设备确定该tyi不包含于第二候选时间单元集合。
本实施例中，第一终端设备可以按照上述S410至S470中的部分或者全部过程对至少一个第一候选时间单元集合中的每个时间单元进行确定，直至确定出第二候选数据单元集合时结束。
