用于侧行传输的方法及终端设备 技术领域
本申请涉及通信技术领域，并且更为具体地，涉及一种用于侧行传输的方法及终端设备。
背景技术
目前，在确定资源池的时域资源时，是通过比特位图以时隙为粒度，来指示对应的时域资源是否属于资源池。也即是说，假设系统帧号(system frame number，SFN)周期包括的时隙的数量为(10240·2μ)个，此时，可以将比特位图在SFN周期内周期性重复，来指示SFN周期内属于该资源池的时隙。例如，比特位图中取值为1的比特位对应的时隙属于资源池。相反地，比特位图中取值为0的比特位对应的时隙不属于资源池。然而，这种以单个时隙为粒度基于比特位图指示时域资源是否属于资源池的方案，并不适用于基于以连续的多个时隙(又称“第一时间单元”)为粒度进行的侧行传输。

第七方面，本申请实施例提供了一种芯片，该芯片包括存储器和处理器，处理器可以从存储器中调用并运行计算机程序，以实现上述各个方面的方法中所描述的部分或全部步骤。
在本申请实施例中，对于基于第一时间单元传输PSCCH和/或PSSCH的资源池，可以通过第一信息来指示一个SFN周期内的属于资源池的时域资源，这种资源指示方式有助于提高与以第一时间单元为粒度传输PSCCH和/或PSSCH的传输方案的匹配程度。

不同网络覆盖情况下的侧行通信
侧行通信指的是基于侧行链路的通信技术。侧行通信例如可以是设备到设备(device to device，D2D)或车联网(vehicle to everything，V2X)通信。传统的蜂窝系统中的通信数据在终端设备和网络设备之间进行接收或者发送，而侧行通信支持在终端设备与终端设备之间直接进行通信数据传输。相比于传统的蜂窝通信，终端设备与终端设备直接进行通信数据的传输可以具有更高的频谱效率以及更低的传输时延。例如，车联网系统采用侧行通信技术。
在侧行通信中，根据终端设备所处的网络覆盖的情况，可以将侧行通信分为网络覆盖内的侧行通信，部分网络覆盖的侧行通信，及网络覆盖外的侧行通信。
图2为网络覆盖内的侧行通信的场景示例图。在图2所示的场景中，两个终端设备120a均处于网络设备110的覆盖范围内。因此，两个终端设备120a均可以接收网络设备110的配置信令(本申请中的配置信令也可替换为配置信息)，并根据网络设备110的配置信令确定侧行配置。在两个终端设备120a均进行侧行配置之后，即可在侧行链路上进行侧行通信。
图3为部分网络覆盖的侧行通信的场景示例图。在图3所示的场景中，终端设备120a与终端设备120b进行侧行通信。终端设备120a位于网络设备110的覆盖范围内，因此终端设备120a能够接收到网络设备110的配置信令，并根据网络设备110的配置信令确定侧行配置。终端设备120b位于网络覆盖范围外，无法接收网络设备110的配置信令。在这种情况下，终端设备120b可以根据预配置(pre-configuration)信息和/或位于网络覆盖范围内的终端设备120a发送的物理侧行广播信道(physical sidelink broadcast channel，PSBCH)中携带的信息确定侧行配置。在终端设备120a和终端设备120b均进行侧行配置之后，即可在侧行链路上进行侧行通信。
图4为网络覆盖外的侧行通信的场景示例图。在图4所示的场景中，两个终端设备120b均位于网络覆盖范围外。在这种情况下，两个终端设备120b均可以根据预配置信息确定侧行配置。在两个终端设备120b均进行侧行配置之后，即可在侧行链路上进行侧行通信。
基于中央控制节点的侧行通信
图5为基于中央控制节点的侧行通信的场景示例图。在该侧行通信场景中，多个终端设备可以构成一个通信组，且该通信组内具有中央控制节点。该中央控制节点可以为通信组内的一个终端设备(如图5中的终端设备1)，该终端设备又可以称为簇头(cluster header，CH)终端设备。该中央控制节点可以负责完成以下功能中的一项或多项：通信组的建立，通信组的组成员的加入和离开，在通信组内进行资源协调，为其他终端设备分配侧行传输资源，接收其他终端设备的侧行反馈信息，以及与其他通信组进行资源协调。
侧行通信的模式
某些标准或协议(如第三代合作伙伴计划(3rd Generation Partnership Project，3GPP))定义了两种侧行通信的模式：第一模式和第二模式。
在第一模式下，终端设备的资源(本申请提及的资源也可称为传输资源，如时频资源)是由网络设备分配的。终端设备可以根据网络设备分配的资源在侧行链路上进行数据的发送。网络设备可以为终端 设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源。该第一模式可以应用于有网络设备覆盖的场景，如前文图2所示的场景。在图2所示的场景中，终端设备120a位于网络设备110的网络覆盖范围内，因此网络设备110可以为终端设备120a分配侧行传输过程中使用的资源。
在第二模式下，终端设备可以自主在资源池(resource pool，RP)中选取一个或多个资源。然后，终端设备可以根据选择出的资源进行侧行传输。例如，在图4所示的场景中，终端设备120b位于小区覆盖范围外。因此，终端设备120b可以在预配置的资源池中自主选取资源进行侧行传输。或者，在图2所示的场景中，终端设备120a也可以在网络设备110配置的资源池中自主选取一个或多个资源进行侧行传输。
侧行通信的数据传输方式
某些侧行通信系统(如长期演进-车联网(long term evolution vehicle to everything，LTE-V2X))支持基于广播的数据传输方式(下文简称广播传输)。对于广播传输，接收端终端可以为发送端终端周围的任意一个终端设备。以图6为例，终端设备1是发送端终端，该发送端终端对应的接收端终端是终端设备1周围的任意一个终端设备，例如可以是图6中的终端设备2-终端设备6。
除了广播传输之外，某些通信系统还支持基于单播的数据传输方式(下文简称单播传输)和/或基于组播的数据传输方式(下文简称组播传输)。例如，新无线-车联网(new radio vehicle to everything，NR-V2X)希望支持自动驾驶。自动驾驶对车辆之间的数据交互提出了更高的要求。例如，车辆之间的数据交互需要更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配方式等。因此，为了提升车辆之间的数据交互性能，NR-V2X引入了单播传输和组播传输。
对于单播传输，接收端终端一般只有一个终端设备。以图7为例，终端设备1和终端设备2之间进行的是单播传输。终端设备1可以为发送端终端，终端设备2可以为接收端终端，或者终端设备1可以为接收端终端，终端设备2可以为发送端终端。
对于组播传输，接收端终端可以是一个通信组内的终端设备，或者，接收端终端可以是在一定传输距离内的终端设备。以图8为例，终端设备1、终端设备2、终端设备3和终端设备4构成一个通信组。如果终端设备1发送数据，则该组内的其他终端设备(终端设备2至终端设备4)均可以是接收端终端。
侧行通信的时隙结构
通信系统可以对侧行通信的帧、子帧或时隙结构进行定义。某些侧行通信系统定义了多种时隙结构。例如，基于NR的侧行通信系统(NR SL)定义了两种时隙结构。该两种时隙结构中的一种时隙结构不包括物理侧行反馈信道(physical sidelink feedback channel，PSFCH)，参见图9A；该两种时隙结构中的另一种时隙结构包括PSFCH，参见图9B。
NR SL中的PSCCH可以以时隙的第二个侧行符号为时域上的起始位置，且PSCCH在时域上可以占用2个或3个符号(这里提及的符号均可以指正交频分复用(orthogonal frequency division multiplexing，OFDM)符号)。PSCCH在频域上可以占用多个物理资源块(physical resource block，PRB)。例如，PSCCH占用的PRB的数量可以从以下数值中选择：{10,12 15,20,25}。
为了降低终端设备对PSCCH进行盲检测的复杂度，通常情况下，在一个资源池内，只为PSCCH配置一种符号数量和PRB数量。另外，由于NR SL将子信道(sub-channel)作为PSSCH资源分配的最小粒度，因此PSCCH占用的PRB数量必须小于或等于资源池内的一个子信道所包含的PRB数量。
参见图9A，对于不包括PSFCH的时隙结构，NR SL中的PSSCH可以以该时隙的第二个侧行符号为时域上的起始位置。该时隙中的最后一个侧行符号用作保护间隔(guard period，GP)，其余符号均可以映射PSSCH，其中，保护间隔又可以称为保护符号(guard symbol)。该时隙中的第一个侧行符号可以是第二个侧行符号的重复。通常而言，作为接收端的终端设备会将第一个侧行符号作为进行自动增益控制(automatic gain control，AGC)的符号。因此，第一个侧行符号上的数据通常不用于数据解调。PSSCH在频域上可以占据K个子信道，每个子信道可以包括M个连续的PRB(K和M的取值可以协议预定义，或预配置，或由网络设备配置，或取决于终端设备实现)。
图9B示出的是包括PSFCH的时隙结构，该图9B示意性地给出了在一个时隙中PSFCH、PSCCH、和PSSCH所占的符号的位置。该时隙结构与图9A的主要区别在于时隙中的倒数第二个符号和倒数第三个符号用于传输PSFCH，此外，在用于传输PSFCH的符号之前的一个符号也用作GP(或保护符号)。从图9B所示的时隙结构可以看出，在一个时隙中，最后一个符号用作GP，倒数第二个符号用于PSFCH传输，倒数第三个符号上的数据和用于PSFCH传输的倒数第二个符号的数据相同，即倒数第三个符号作为进行AGC的符号，倒数第四个符号和最后一个符号的作用相同，也用作GP。此外，时隙中的第一个符号用作AGC，该符号上的数据和该时隙中第二个符号上的数据相同，PSCCH占据3个符号，剩余的符号可用于PSSCH传输。
PSBCH及PSBCH的DMRS结构
侧行通信系统(如NR SL)中的S-SSB包括侧行同步信号和PSBCH，而侧行同步信号又分为侧行主同步信号(sidelink primary synchronization signal，S-PSS)和侧行辅同步信号(sidelink secondary synchronizatio signal，S-SSS)，S-SSB又可称为S-SS/PSBCH块。
在时域上，S-PSS占据一个时隙中的第2个、第3个符号。S-SSS占据一个时隙中的第4个、第5个符号。一个时隙中的最后一个符号为GP(或保护符号)，其余符号用于传输PSBCH。S-PSS和S-SSS在时域上是连续的，这样可以将基于S-PSS获取的信道估计结果应用于S-SSS检测，从而有利于提高S-SSS的检测性能。
在频域上，PSBCH占用11个连续的PRB，即132个子载波(每个PRB包括12个子载波)。S-PSS和S-SSS的长度为127，因此，在S-PSS和S-SSS所在的符号上，子载波#0，#1，#129，#130和#131置为零，如图10所示。
在PSBCH占用的每个符号上均包括PSBCH DMRS，并且该PSBCH DMRS映射到每个PSBCH所占用的RB中的子载波#0、子载波#4和子载波#8。
通信系统的新频段(高频)
某些通信系统(如NR系统)的研究目前主要考虑如下两个频段：频率范围1(frequency range 1，FR1)和频率范围2(frequency range 2，FR2)。FR1和FR2包括的频段如下面的表1所示。
表1：FR1和FR2对应频段的定义
随着通信系统(如NR系统)的演进，新频段(通常称为高频)上的技术也开始被研究。这里提及的新频段的频率可以高于FR1和FR2，例如可以包括如下面的表2所示的频率范围。
表2：新频段的一种可能的定义方式
这里采用FRX表示该新频段，仅是为了与FR1和FR2进行区分，并不是为了对新频段的名称进行限定。例如，也可以将FRX称为FR3。又如，可以将上述表1中的FR2记为FR2-1，将表2中的FRX记为FR2-2。当然，除了上面列举的两种方式之外，还可以采用其他方式标识该新频段，本申请对此不作具体限定。
FRX频段中可以包括授权频谱，也包括非授权频谱。或者说，FRX频段中可以包括共享频谱，也包括非共享频谱。这里提及的非授权频谱通常是由国家或地区划分的可用于无线电设备通信的频谱，且该非授权频谱通常被认为是由不同通信系统中的通信设备所共享的频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用非授权频谱必须满足的法规要求。例如，通信设备遵循“先听后说(listen before talk，LBT)”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送。如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，则该通信设备不能进行信号发送。又如，为了保证公平性，在一次传输中，通信设备使用非授权频谱的信道进行信号传输的时长不能超过一定时间长度。又如，为了避免在非授权频谱的信道上传输的信号的功率太大，影响该信道上的其他重要信号的传输，通信设备使用非授权频谱的信道进行信号传输时需要遵循不超过最大功率谱密度的限制。
FRX频段的子载波间隔可以比FR2的子载波间隔更大。目前，FRX频段的候选子载波间隔可以包括以下中的一种或多种：120kHz、240kHz、480kHz、960kHz、1.92MHz、3.84MHz。以子载波间隔为120kHz，480kHz以及960kHz为例，上述候选子载波间隔下对应的参数集(numerology)如下表3所示。
表3：候选子载波间隔对应的参数集
为了提升侧行通信系统的传输速率，可以考虑在侧行通信系统中引入新频段。该新频段可以是指毫 米波频段。或者，该新频段可以是指频率高于52.6GHz的频段，例如可以是前文提到的频段范围在52.6GHz-71GHz之间的FRX(或FR2-2)频段。
不同的频率范围内支持的子载波间隔可能是不同的。例如，FR1可以支持15kHz、30kHz和60kHz的子载波间隔。FR2-1可以支持60kHz和120kHz的子载波间隔。FRX可以支持120kHz及120kHz以上的子载波间隔，如FRX可以支持120kHz、480kHz和960kHz的子载波间隔。
相关技术定义了如下子载波间隔对应的时隙结构：15kHz、30kHz、60kHz和120kHz。但是，当子载波间隔大于120kHz时，如当子载波间隔达到480kHz和960kHz时，侧行通信系统的时隙结构应当如何设计，目前还未讨论。
针对上述问题，一种可能的时隙结构设计方案是继续沿用图9A和图9B所示的时隙结构。但是，仔细研究会发现，如果继续沿用图9A和图9B所示的时隙结构，会导致通信过程难以实现，具体原因论述如下。
如图9A或图9B所示，在用于侧行通信的一个时隙中，第一个符号通常为AGC符号，供接收端设备进行AGC调整(adjustment)或AGC训练(training)；最后一个符号用作GP，通常用于终端设备的收发转换(RX/TX switching)或发收转换(TX/RX switching)。当子载波间隔不同时，一个符号对应的时长不同。例如，当子载波间隔为15kHz时，一个符号对应的时长约为66.7us。如果加上循环前缀(cyclic prefix，CP)对应的4.69us的时长，当子载波间隔为15kHz时，一个符号的总时长约为71us～72us。又如，当子载波间隔为120kHz时，一个符号的总时长(符号和CP长度之和)约为8us～9us。因此，当子载波间隔为120kHz时，AGC调整时间不超过8us～9us，终端设备的收发转换时间或发收转换时间约为7us。
FR1和FR2(可以包括前文提到的FR2-1和FR2-2)中的转换时间对应的时长可以基于下面的表4确定。
表4：收发转换时间和发收转换时间
表4中的数值表示时间单位(time unit)的数量。一个时间单位Tc对应的时长可以采用下式确定：Tc＝1/(Δfmax·Nf)，其中，Δfmax＝480·103Hz，Nf＝4096。
当子载波间隔大于120kHz时，一个符号对应的时长会继续缩短。例如，当侧行系统的子载波间隔为480kHz时，一个符号的时长约为2us～3us(如表3所示)；当侧行系统的载波间隔为960kHz时，一个符号的时长约为1us(如表3所示)。由此可见，随着频率的增加，一个符号对应的时长可能太短，导致终端设备很难在这么短的时间内完成AGC调整，收发转换或发收转换。因此，需要更多的符号用于AGC调整、收发转换(或发收转换)。但是，如果多个符号用作AGC或GP，用于侧行数据传输的符号数量会变得比较少，从而会大大降低通信系统的传输效率。
针对上述问题，本申请实施例提出一种可用于侧行传输的时间单元(详见实施例1)，该时间单元可以包括多个时隙，从而可以在一定程度缓解符号对应的时长过短所带来的问题。为了方便描述，后文主要站在第一时间单元的角度进行介绍。该第一时间单元可以是用于侧行通信的某一类时间单元。侧行通信过程可能会涉及PSSCH、PSCCH、PSFCH以及S-SSB中的一种或多种的传输，为了便于理解，先结合实施例1介绍基于第一时间单元进行侧行传输的方案。
实施例1：包含连续的M1个时隙的第一时间单元
该第一时间单元可以包括连续的M1个时隙(M1为大于1的正整数)。该第一时间单元也可以理解为一种基于多时隙的时隙结构。在一些实现方式中，可以将该第一时间单元称为：聚合时隙(aggregate slot)、时隙聚合(slot aggregation)、超级时隙(super slot)、时隙组(slot group)或者多时隙(multiple slot或multi-slot)。
在一些实现方式中，M1的取值可以基于以下中的一种或多种确定：协议预定义信息；资源池配置信息；侧行BWP配置信息；或者终端设备的指示信息。该终端设备可以是侧行数据的发送端设备，也可以是侧行数据的接收端设备。
在一些实现方式中，第一时间单元包括的M1个时隙为连续的M1个物理时隙。物理时隙是相对于逻辑时隙而言的。通常来说，属于资源池的时隙称为逻辑时隙，而一个系统帧号(system frame number，SFN)周期(包括10240ms)中包括的个时隙称为物理时隙。μSL是与侧行子载波间隔相关的参数，μSL的取值可以基于表5确定。
表5

资源池内连续的时隙可能并非是连续的物理时隙。如果将连续的M1个时隙设置为资源池中连续的M1个时隙，则该M1个时隙的中间有可能包括属于其他资源池的时隙。这样一来，终端设备在利用该M1个时隙进行传输时，有可能需要在属于其他资源池的时隙上进行接收，从而导致额外的GP开销用于收发转换。因此，将M1个时隙设置为连续的M1个物理时隙，有可能会降低收发转换带来的GP开销。
在一些实现方式中，第一时间单元包括的M1个时隙为连续的可用于侧行传输的时隙(资源池中的时隙是从可用于侧行传输的时隙中确定的)。
在一些实现方式中，第一时间单元可以包括PSCCH传输资源和PSSCH传输资源。或者，第一时间单元可以包括PSCCH传输资源，PSSCH传输资源以及PSFCH传输资源。下面结合图11和图12，对第一时间单元中的各个符号的用途进行举例说明。在图11和图12所示的第一时间单元中，第一个用于传输PSCCH或PSSCH的符号位于第一时间单元中的第A+1个符号，即第一时间单元中的前A个符号为AGC符号，可以用作AGC调整或AGC训练，第一时间单元中的最后B1个符号为保护符号或GP符号。

实施例1.1：第一时间单元中的保护符号
保护符号也可称为用作GP的符号。在一些实现方式中，保护符号可用于终端设备进行收发转换或发收转换。在一些实现方式中，保护符号上可以不映射任何数据。
在一些实现方式中，第一时间单元可以包括第一保护符号。第一保护符号包括连续的B1个符号，且B1个符号为第一时间单元的最后B1个符号，B1为大于1的正整数。
在一些实现方式中，第一时间单元可以包括第一保护符号。第一保护符号包括连续的B1个符号，且B1个符号为第一时间单元的最后B1个可用于侧行传输的符号，B1为大于1的正整数。
在一些实现方式中，第一保护符号位于第一时间单元的最后一个时隙中。
在一些实现方式中，如果第一时间单元包括用于传输PSFCH的时域资源1，则第一时间单元可以包括第二保护符号。第二保护符号包括连续的B2个符号，B2为大于1的正整数。第二保护符号内的B2个符号可以位于时域资源1之前。该B2个符号可以与时域资源1相邻，也就是说，该B2个符号的最后一个符号与时域资源1的第一个符号为第一时间单元中的相邻符号。
在一些实现方式中，第二保护符号位于第一时间单元的最后一个时隙和/或倒数第二个时隙中。
在一些实现方式中，B1与B2的取值相同。例如，B1与B2均等于B，B为大于1的正整数。在另一些实现方式中，B1与B2的取值不同。例如，B1大于B2，或者，B2大于B1。
下面对B的取值的确定方式进行详细描述。应理解，B的取值的确定方式可以适用于前文提到的B1，也可以适用于前文提到的B2。
在一些实现方式中，B的取值等于4。进一步地，在一些实现方式中，如果B的取值等于4，则第一时间单元对应的侧行子载波间隔为480kHz。例如，在图11A、图11C、图11D、图12A、图12C、图12E、图13A、图13B、图13E所示的时间单元的示例中，B的取值为4。
在一些实现方式中，B的取值等于8。进一步地，在一些实现方式中，如果B的取值等于8，则第一时间单元对应的侧行子载波间隔为480kHz或960kHz。例如，在图11B、图12B、图12D、图12F、图13C、图13D、图13F所示的时间单元的示例中，B的取值为8。

在一些实现方式中，B的取值可以基于第一指示信息确定。该第一指示信息可用于指示以下中的一种或多种：B的取值；一个时隙中或一个时间单元(本申请各个实施例提及的时间单元均可以指包含连续的M1个时隙的时间单元，或包含连续的M1个可用于侧行传输的时隙的时间单元，后文不再赘述)中的可用于侧行传输的第一个符号的时域位置；一个时间单元中的可用于侧行传输的符号的长度或数量；以及一个时间单元包括的时隙的数量。
作为一个示例，第一指示信息可用于直接指示B的取值。或者，B的取值可以基于第一指示信息指示的值确定。
作为另一示例，第一指示信息可以包括信息1和信息2。信息1指示一个时隙中或一个时间单元中的可用于侧行传输的第一个符号的时域位置。信息2指示一个时间单元中的可用于侧行传输的符号的长度或数量。根据信息1和信息2即可确定B的取值。例如，信息1指示一个时间单元中的可用于侧行传输的第一个符号的时域位置为符号0；信息2指示一个时间单元中的可用于侧行传输的符号的数量为24。根据信息1和信息2，可以假设第一时间单元包括2个时隙，在正常CP的情况下，第一时间单元包括28个符号，因此用作GP的符号数量为4，即B的取值为4。
作为又一示例，第一指示信息可以包括信息3。该信息3指示一个时间单元中的可用于侧行传输的符号的长度或数量。根据该信息3即可确定B的取值。例如，信息3指示一个时间单元中的可用于侧行传输的符号的数量为24。该信息3指示的取值大于一个时隙包括的符号数量，小于两个时隙包括的符号数量，因此可以假设第一时间单元包括两个时隙，且该两个时隙均可用于侧行传输。在正常CP的情况下，两个时隙一共包括28个符号，因此GP的符号数量为4，即B的取值为4(在该示例中，假设 第一时间单元中的侧行传输资源对应的起始符号为第一时间单元的第一个符号)。
作为又一示例，第一指示信息可以包括信息4和信息5。该信息4指示一个时间单元中的可用于侧行传输的符号的长度或数量。该信息5指示一个时间单元包括的时隙的数量。根据该信息4和信息5即可确定B的取值。例如，信息4指示一个时间单元中的可用于侧行传输的符号的数量是24，信息5指示一个时间单元包括2个时隙。在正常CP的情况下，两个时隙一共包括28个符号，因此GP的符号数量为4，即B的取值为4(在该示例中，假设第一时间单元中的侧行传输资源对应的起始符号为第一时间单元的第一个符号)。
在一些实现方式中，上述第一指示信息可以包含在资源池配置信息或侧行BWP配置信息中。或者，该第一指示信息可以由终端设备指示。该终端设备可以是侧行数据的发送端设备，也可以是侧行数据的接收端设备。
在一些实现方式中，B的取值可以基于第一侧行子载波间隔和第二侧行子载波间隔确定。该第一侧行子载波间隔和第二侧行子载波间隔不同。
在一些实现方式中，该第一侧行子载波间隔可以大于该第二侧行子载波间隔。
在一些实现方式中，该第一侧行子载波间隔为第一时间单元对应的侧行子载波间隔。
在一些实现方式中，该第一子载波间隔基于协议预定义信息、资源池配置信息或侧行BWP配置信息确定。以第一侧行子载波间隔基于侧行BWP配置信息确定为例，则该侧行BWP配置信息可用于配置第一时间单元所对应的BWP。
在一些实现方式中，该第二子载波间隔基于协议预定义信息、资源池配置信息或侧行BWP配置信息确定。该第二子载波间隔有时也可称为参考子载波间隔。
在一些实现方式中，该第一侧行子载波间隔为480kHz或960kHz。
在一些实现方式中，该第二子载波间隔为15kHz、30kHz，60kHz或120kHz。
例如，第一侧行子载波间隔采用μSL1表示，第二侧行子载波间隔采用μSL2表示，且B满足：假设μSL1＝5，μSL2＝3，即第一侧行子载波间隔为480kHz的子载波间隔，第二侧行子载波间隔为120kHz的子载波间隔，在这种情况下，B＝4。假设μSL1＝6，μSL2＝3，即第一侧行子载波间隔为960kHz子载波间隔，第二侧行子载波间隔为120kHz的子载波间隔，在这种情况下，B＝8。
在一些实现方式中，第一时间单元包含的M1个时隙中的至少一个时隙不包括保护符号。作为一种实现方式，第一时间单元包含的M1个时隙中的除最后一个时隙之外的剩余时隙不包括保护符号。
例如，在图11A和图11B中，第一时间单元包括2个时隙，即时隙n和时隙n+1。时隙n+1包括用作GP的保护符号，时隙n不包括用作GP的保护符号。
又如，在图12A和图12B中，第一时间单元包括4个时隙，即时隙n、时隙n+1、时隙n+2和时隙n+3。时隙n+3包括用作GP的保护符号，时隙n、n+1、n+2不包括用作GP的保护符号。
在一些实现方式中，如果第一时间单元包括用于传输PSFCH的时域资源，则该M1个时隙中的最后一个时隙和/或倒数第二个时隙包括保护符号。进一步地，在一些实现方式中，除该M1个时隙中的最后一个时隙和/或倒数第二个时隙之外的剩余时隙不包括保护符号。
实施例1.2：第一时间单元中的PSCCH的时频资源
在一些实现方式中，第一时间单元包括用于传输PSCCH的时域资源。用于传输PSCCH的时域资源的起始符号为第一时间单元的第A+1个符号。A为大于1的正整数。
在一些实现方式中，A的取值等于4。进一步地，在一些实现方式中，如果A的取值等于4，则第一时间单元对应的侧行子载波间隔为480kHz。例如，在图11A、图11C、图11D、图12A、图12C、图12E所示的时间单元的示例中，A的取值为4。
在一些实现方式中，A的取值等于8。进一步地，在一些实现方式中，如果A的取值等于8，则第一时间单元对应的侧行子载波间隔为480kHz或960kHz。例如，在图11B、图12B、图12D、图12F所示的时间单元的示例中，A的取值为8。
在一些实现方式中，A的取值基于以下信息中的一种或多种确定：协议预定义信息；资源池配置信息；侧行BWP配置信息；或者终端设备的指示信息。该终端设备可以是侧行数据的发送端设备，也可以是侧行数据的接收端设备。
在一些实现方式中，A的取值基于第二指示信息确定。例如，第二指示信息可用于指示以下中的一种或多种：A的取值；一个时间单元中的可用于传输PSSCH的第一个符号的时域位置；一个时间单元中的可用于传输PSCCH的第一个符号的时域位置；一个时间单元中用于映射PSSCH的第一个符号的时域位置；一个时间单元中用于映射PSCCH的第一个符号的时域位置；一个时间单元中PSSCH资源分配的第一个符号的时域位置；一个时间单元中PSCCH资源分配的第一个符号的时域位置；以及一个时隙中或一个时间单元中的可用于侧行传输的第一个符号的时域位置。
作为一个示例，该第二指示信息直接指示A的取值。或者，A的取值基于第二指示信息指示的取值确定。
作为另一示例，该第二指示信息指示一个时间单元中的可用于传输PSSCH或PSCCH的第一个符号的时域位置。根据该第二指示信息，即可确定A的取值。例如，该第二指示信息指示PSSCH的第一个符号位置为第一时间单元中的第5个符号，则A的取值为4(在该示例中，假设第一时间单元中的侧行传输资源对应的起始符号为第一时间单元的第一个符号)。
作为又一示例，该第二指示信息可以指示信息6和信息7。信息6可用于指示一个时间单元中的可用于传输PSSCH或PSCCH的第一个符号的时域位置。信息7可用于指示一个时隙中或一个时间单元中的可用于侧行传输的第一个符号的时域位置。根据该信息6和该信息7即可确定A的取值。例如，该信息6指示可用于传输PSSCH的第一个符号的时域位置为符号6，该信息7指示一个时隙中可用于侧行传输的第一个符号的时域位置为符号2。根据该信息6和信息7，可以确定A的取值为4。
在一些实现方式中，第二指示信息可以包含在资源池配置信息或侧行BWP配置信息中。或者，该第二指示信息可以为终端设备的指示信息。该终端设备可以是侧行数据的发送端设备，也可以是侧行数据的接收端设备。
在一些实现方式中，A的取值基于第三侧行子载波间隔和第四侧行子载波间隔确定。该第三侧行子载波间隔和第四侧行子载波间隔不同。

在一些实现方式中，该第三侧行子载波间隔为第一时间单元对应的侧行子载波间隔。
在一些实现方式中，该第三侧行子载波间隔基于侧行BWP配置信息确定，该侧行BWP配置信息用于配置第一时间单元所对应的BWP。
在一些实现方式中，该第三子载波间隔基于协议预定义信息、资源池配置信息或侧行BWP配置信息确定。
在一些实现方式中，该第三侧行子载波间隔为480kHz或960kHz。
在一些实现方式中，该第四侧行子载波间隔为15kHz、30kHz，60kHz或120kHz。
在一些实现方式中，该第三侧行子载波间隔等于前文提到的第一侧行子载波间隔；和/或，该第四侧行子载波间隔等于前文提到的第二侧行子载波间隔。
例如，第三侧行子载波间隔采用μSL3表示，第四侧行子载波间隔采用μSL4表示，且A满足：假设μSL＝5，μSL＝3，即第三侧行子载波间隔为480kHz的子载波间隔，第四侧行子载波间隔为120kHz的子载波间隔，在这种情况下，A＝4。假设μSL3＝6，μSL＝3，即第三侧行子载波间隔为960kHz子载波间隔，第四侧行子载波间隔为120kHz的子载波间隔，在这种情况下，A＝8。
在一些实现方式中，第一时间单元的前A个符号(或第一时间单元的前A个可用于侧行传输的符号)用作AGC。
在一些实现方式中，第一时间单元的前A个符号(或第一时间单元的前A个可用于侧行传输的符号)中的数据为第一时间单元的目标符号中的数据的重复数据。该目标符号可以包括第一时间单元中的除前A个符号之外的剩余符号中的一个或多个符号。
在一些实现方式中，该目标符号为第一时间单元的第A+1个符号至第2A个符号。也就是说，第一时间单元的前A个符号中的数据为该第一时间单元的第A+1个符号至第2A个符号中的数据的重复数据。例如，第一时间单元的第1个符号上的数据是第一时间单元的第A+1个符号上数据的重复数据；第一时间单元的第2个符号上的数据是第一时间单元的第A+2个符号上数据的重复数据；以此类推，第一时间单元的第A个符号上的数据是第一时间单元的第2A个符号上数据的重复数据。
在一些实现方式中，该目标符号为第一时间单元的第A+1个符号。也就是说，第一时间单元的前A个符号中的数据均为该第一时间单元的第A+1个符号中的数据的重复数据。由此可见，在该实现方式中，第一时间单元的前A个符号和第A+1个符号传输相同的数据。
在一些实现方式中，该时域资源2包括连续的P个符号。P的取值可以为大于或等于1的正整数。P的取值例如可以为3。

A的取值的确定方式可以参见实施例1.2的描述，为了避免重复，此处不再详述。或者，在一些实施例中，实施例1.2中的A可以为A1，实施例1.3中的A可以为A2，A1和A2可以相同，也可以不同。
在一些实现方式中，如果第一时间单元不包括PSFCH传输资源，则时域资源3的结束符号为第一保护符号对应的符号的前一符号。该第一保护符号的相关描述可以参见前文中的实施例1.1，此处不再详述。例如，图11A中，PSSCH的时域资源包括从时隙n的第5个符号开始至时隙n+1的倒数第5个符号为止。图11B中，PSSCH的时域资源包括从时隙n的第9个符号开始至时隙n+1的第6个符号(也就是倒数第9个符号)为止。图12A中，PSSCH的时域资源包括从时隙n的第5个符号开始至时隙n+3的倒数第5个符号为止。图12B中，PSSCH的时域资源包括从时隙n的第9个符号开始至时隙n+3的第6个符号(也就是倒数第9个符号)为止。
在一些实现方式中，时域资源3的结束符号为第一时间单元中的最后一个可用于传输PSSCH的符号。
在一些实现方式中，如果第一时间单元包括PSFCH传输资源，则时域资源3的结束符号为第二保护符号对应的符号的前一符号。该第二保护符号的相关描述可以参见前文中的实施例1.1，此处不再详述。例如，图11C中，PSSCH的时域资源包括从时隙n的第5个符号开始至时隙n+1的第1个符号为止。图12C中，PSSCH的时域资源包括从时隙n的第5个符号开始至时隙n+3的第1个符号为止；图12D中，PSSCH的时域资源包括从时隙n的第9个符号开始至时隙n+2的第3个符号为止。
实施例2
如相关技术中介绍，目前在确定资源池的时域资源时，是通过比特位图以时隙为粒度，来指示对应的时域资源是否属于资源池。也即是说，假设SFN周期包括的时隙的数量为(10240·2μ)个，此时，可以将比特位图在SFN周期内周期性重复，来指示SFN周期内属于该资源池的时隙。例如，比特位图中取值为1的比特位对应的时隙属于资源池。相反地，比特位图中取值为0的比特位对应的时隙不属于资源池。然而，这种以单个时隙为粒度基于比特位图指示时域资源是否属于资源池的方案，并不适用于上述基于第一时间单元进行的侧行传输。
因此，针对上述问题，本申请实施例提供了一种用于指示一个SFN周期内的时域资源是否属于资源池的方案，有助于与以第一时间单元为粒度进行侧行传输的传输方案匹配。为了便于理解，下文结合图14介绍本申请实施例的用于侧行传输的方法。
图14是本申请实施例的用于侧行传输的方法的示意性流程图。图14所示的方法可以包括步骤S1410。
在步骤S1410中，第一终端设备确定第一信息，其中，第一信息用于指示一个SFN周期内的属于资源池的时域资源。
在一些实现方式中，第一信息可以包括比特位图，或者说，第一信息可以用于指示比特位图。相应地，可以基于比特位图确定对一个SFN周期内的属于资源池的时域资源。
在一些实现方式中，第一信息可以以第一时间单元为粒度指示对应的时域资源是否属于资源池，或者说，第一信息中的1个比特可以对应SFN周期内的一个第一时间单元。例如，第一信息中的目标比特位可以对应SFN周期内的第一时间单元，相应地，目标比特位的取值为1时，目标比特位对应的第一时间单元属于资源池。当然，在本申请实施例中，第一信息也可以以时隙为粒度指示SFN周期内的时域资源是否属于资源池。
在一些实现方式中，上述资源池可以基于第一时间单元传输PSCCH和/或PSSCH，第一时间单元包含连续的M1个时隙，且M1为大于1的正整数。其中，以第一时间单元传输PSCCH和/或PSSCH的方案可以参见上文关于实施例1的介绍。
在一些实现方式中，上述侧行传输包括S-SSB的传输，其中，S-SSB的传输包括基于第一时间单元 或第二时间单元传输S-SSB，其中，以第一时间单元或者以第二时间单元传输S-SSB的方案可以参见上文关于实施例1的介绍。
需要说明的是，在本申请实施例对时域资源不作限定，例如，时域资源可以包括时隙。又例如，时域资源可以包括符号，当然，上述时域资源还可以包括未来通信系统中规定的其他时域资源粒度。
为了便于理解，下文分别以基于第一时间单元传输S-SSB，以及基于第二时间单元传输S-SSB为例，结合实施例2-1以及实施例2-2介绍本申请实施例的用于侧行传输的方案。
实施例2-1：基于第一时间单元传输S-SSB。
在一些场景中，SFN周期内不能用于侧行传输的时域资源(又称“第二时域资源”，用“NnonSL”表示该时域资源包括的时域资源的数量)，用于传输S-SSB的时域资源(又称“第一时域资源”，用“NS-SSB”表示该时域资源包括的时域资源的数量)以及预留的时域资源(又称“第三时域资源”，用“Nreserved”表示该时域资源包括的时域资源的数量)中的一种或多种不属于资源池，因此，在指示属于资源池的时域资源时，还需要考虑上述一种或多种资源。
换句话说，假设第一集合包括多个第一时间单元，相应地，属于资源池的时域资源从第一集合中确定，则第一集合基于以下中的一种或多种确定：第一时域资源、第二时域资源、以及第三时域资源。
在一些实现方式中，如果一个时隙中的可用于侧行传输的第一个符号为一个时隙中的第一个符号，则SFN周期内的不能用于侧行传输的时隙的数量的取值为0，即NnonSL＝0。
需要说明的是，上述预留的时域资源例如可以是预留的时间单元，或者预留时隙(reserved slot)。当然，在本申请实施例中，上述预留的时域资源还可以是预留的时域符号，本申请实施例对此不作限定。
另外，在本申请实施例中，上述NnonSL、NS-SSB以及Nreserved可以为大于或等于0的正整数。
如上文介绍，上述第一时域资源、第二时域资源、以及第三时域资源中的一种或多种资源不属于资源池，因此，在确定第一集合时可以将上述一种或多种时域资源从一个SFN周期包括的时域资源中排除。
在一些实现方式中，第一集合中包括的第一时间单元的数量或时隙数量可以基于以下信息中的一种或多种确定：一个SFN周期包括的时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的时隙数量，第二时域资源包括的时隙数量，第三时域资源包括的时隙数量。
在又一些实现方式中，第一集合中包括的第一时间单元的数量或时隙数量可以基于以下信息中的一种或多种确定：一个SFN周期包括的第一时间单元的数量，第一时间单元包括的时隙数量，第一时域资源包括的第一时间单元的数量，第二时域资源包括的第一时间单元的数量，第三时域资源包括的第一时间单元的数量。
在一些实现方式中，一个SFN周期包括的时域资源对应的第一时间单元的数量为10240×2μ/M1，索引范围为[0,10240×2μ/M1-1]。若NS-SSB表示第一时域资源对应的第一时间单元的数量，NnonSL表示第二时域资源对应的第一时间单元的数量，Nreserved表示第三时域资源对应的第一时间单元的数量，则第一集合中包括的第一时间单元的数量为10240×2μ/M1-NS-SSB-NnonSL-Nreserved。
在一些实现方式中，第一集合中包括的第一时间单元的数量可以基于第一数量确定，第一数量等于10240×2μ/M1-NS-SSB-NnonSL-Nreserved。
上述μ表示基于侧行子载波间隔确定的参数(μ的取值例如可以参考表5的相关介绍)。
上述NS-SS表示基于第一时域资源包括的第一时间单元的数量确定的参数。在一些实现方式中，NS-SSB可以等于第一时域资源包括的第一时间单元的数量。在另一些实现方式中，NS-SSB还可以是通过对第一时域资源包括的第一时间单元的数量进行计算得到的，例如，可以通过对第一时域资源包括的第一时间单元的数量乘以一个权值得到NS-SSB。在另一些实现方式中，NS-SSB还可以是通过对第一时域资源包括的时隙数量进行计算得到的，例如，可以通过对第一时域资源包括的时隙数量除以第一时间单元包括的时隙数量(即M1)得到NS-SSB。本申请实施例对计算NS-SSB的方式不作具体限定。
上述NnonSL表示基于第二时域资源包括的第一时间单元的数量确定的参数。在一些实现方式中，NnonSL可以等于第二时域资源包括的第一时间单元的数量。在另一些实现方式中，NnonSL还可以是通过对第二时域资源包括的第一时间单元的数量进行计算得到的，例如，可以通过对第二时域资源包括的第一时间单元的数量乘以一个权值得到NnonSL。在另一些实现方式中，NnonSL还可以是通过对第二时域资源包括的时隙数量进行计算得到的，例如，可以通过对第二时域资源包括的时隙数量除以第一时间单元包括的时隙数量(即M1)得到NnonSL。本申请实施例对计算NnonSL的方式不作具体限定。
上述Nreserved表示基于第三时域资源包括的第一时间单元的数量确定的参数。在一些实现方式中，Nreserved可以等于第三时域资源包括的第一时间单元的数量。在另一些实现方式中，Nreserved还可以是通过对第三时域资源包括的第一时间单元的数量进行计算得到的，例如，可以通过对第三时域资源包括的第一时间单元的数量乘以一个权值得到Nreserved。在另一些实现方式中，Nreserved还可以是通过对第 三时域资源包括的时隙数量进行计算得到的，例如，可以通过对第三时域资源包括的时隙数量除以第一时间单元包括的时隙数量(即M1)得到Nreserved。本申请实施例对计算Nreserved的方式不作具体限定。
在一些实现方式中，一个SFN周期包括的时域资源对应的时隙数量为10240×2μ，索引范围为[0,10240×2μ-1]。若NS-SSB表示第一时域资源对应的时隙数量，NnonSL表示第二时域资源对应的时隙数量，Nreserved表示第三时域资源对应的时隙数量，则第一集合中包括的时隙数量为10240×2μ-NS-SSB-NnonSL-Nreserved，第一集合中包括的第一时间单元的数量为(10240×2μ-NS-SSB-NnonSL-Nreserved)/M1。
在又一些实现方式中，第一集合中包括的第一时间单元的数量可以基于第三数量确定，第三数量等于(10240×2μ-NS-SSB-NnonSL-Nreserved)/M1。
上述μ表示基于侧行子载波间隔确定的参数(μ的取值例如可以参考表5的相关介绍)。
上述NS-SSB表示基于第一时域资源包括的时隙的数量确定的参数。在一些实现方式中，NS-SSB可以等于第一时域资源包括的时隙数量。在另一些实现方式中，NS-SSB还可以是通过对第一时域资源包括的时隙数量进行计算得到的，例如，可以通过对第一时域资源包括的时隙数量乘以一个权值得到NS-SSB。在另一些实现方式中，NS-SSB还可以是通过对第一时域资源包括的第一时间单元的数量进行计算得到的，例如，可以通过对第一时域资源包括的第一时间单元的数量乘以第一时间单元包括的时隙数量(即M1)得到NS-SS。本申请实施例对计算NS-SSB的方式不作具体限定。
上述NnonSL表示基于第二时域资源包括的时隙数量确定的参数。在一些实现方式中，NnonSL可以等于第二时域资源包括的时隙数量。在另一些实现方式中，NnonSL还可以是通过对第二时域资源包括的时隙数量进行计算得到的，例如，可以通过对第二时域资源包括的时隙数量乘以一个权值得到NnonSL。在另一些实现方式中，NnonSL还可以是通过对第二时域资源包括的第一时间单元的数量进行计算得到的，例如，可以通过对第二时域资源包括的第一时间单元的数量乘以第一时间单元包括的时隙数量(即M1)得到NnonSL。本申请实施例对计算NnonSL的方式不作具体限定。

需要说明的是，本申请实施例中以第一集合中包括的第一时间单元的数量基于第一数量确定为例进行说明，本申请实施例同样适用于第一集合中包括的第一时间单元的数量基于第三数量确定的情况。
在一些实现方式中，第一集合用于表示一个SFN周期内可能属于资源池的时间单元集合。
在一些实现方式中，，第一集合(或者说，一个SFN周期内可能属于资源池的时间单元集合)可以表示为：其中，表示第一集合中的第i个第一时间单元，Tmax可以是基于一个SFN周期内包括的时域资源排除第一时域资源、第二时域资源、以及第三时域资源之后剩余的时域资源的数量确定的。例如，Tmax可以是等于一个SFN周期包括的第一时间单元的数量减去第一时域资源对应的第一时间单元的数量、第二时域资源对应的第一时间单元的数量、以及第三时域资源对应的第一时间单元的数量之后剩余的第一时间单元的数量。
在一些实现方式中，将一个SFN周期包括的第一时间单元排除第一时域资源对应的第一时间单元、第二时域资源对应的第一时间单元、以及第三时域资源对应的第一时间单元之后剩余的第一时间单元按照时间单元索引递增的顺序重新进行索引得到第一集合。
上文介绍了本申请实施例中第一集合的确定方式，下文介绍本申请实施例中第三时域资源包括的第一时间单元的数量的确定方式，以及第三时域资源的确定方式。
在一些实现方式中，上述第三时域资源包括的第一时间单元的数量基于以下中的一种或多种确定：第一时域资源包括的第一时间单元的数量；第二时域资源包括的第一时间单元的数量；以及第一信息对应的比特数量。
在另一些实现方式中，上述第三时域资源包括的第一时间单元的数量基于以下中的一种或多种确定：一个SFN周期包括的第一时间单元的数量或时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的第一时间单元的数量；第二时域资源包括的第一时间单元的数量；以及第一信息对应的比特数量。
以第一信息用于指示比特位图为例，上述第一信息对应的比特数量，可以理解为是比特位图包括的比特数量。
在一些实现方式中，第三时域资源包括的第一时间单元的数量满足：Nreserved＝(10240×2μ/M1- NS-SSB-NnonSL)mod L，其中，L表示第一信息对应的比特数量，其余参数可以参见上文的介绍。也即是说，第三时域资源包括的第一时间单元的数量的设置使得一个SFN周期中包括的第一时间单元的数量减去第一时域资源包括的第一时间单元的数量NS-SSB、第二时域资源包括的第一时间单元的数量NnonSL以及第二时域资源包括的第一时间单元的数量Nreserved后，的剩余的第一时间单元的数量能够被第一信息对应的比特数量整除。
在一些实现方式中，上述第三时域资源基于以下中的一种或多种从第二集合中确定：第一时域资源包括的第一时间单元的数量；第二时域资源包括的第一时间单元的数量；第三时域资源包括的第一时间单元的数量。
在一些实现方式中，上述第三时域资源基于以下中的一种或多种从第二集合中确定：一个SFN周期包括的第一时间单元的数量或时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的第一时间单元的数量；第二时域资源包括的第一时间单元的数量；第三时域资源包括的第一时间单元的数量。
上述第二集合中的时间单元为SFN周期包含的时域资源中的目标时域资源对应的时间单元，目标时域资源为SFN周期包含的时域资源中的除第一时域资源和第二时域资源之后剩余的时域资源。
在一些实现方式中，将SFN周期包含的时域资源中的除第一时域资源和第二时域资源之后剩余的时域资源按照索引从低到高的顺序重新进行索引。第二集合例如可以表示为
在一些实现方式中，第三时域资源包括第二集合中的第r个时间单元，其中，r为整数，0≤r<10240×2μ/M1-NS-SSB-NnonSL，且其中，表示向下取整操作，m＝0,1,…,Nreserved-1，其他相关参数可以参见上文的介绍，为了简洁，在此不再赘述。
上文介绍了本申请实施例中第三时域资源的确定方式，下文介绍本申请实施例中从第一集合中确定属于资源池的时间单元的方法。
在一些实现方式中，第一信息为比特位图，如果比特位图中的第k′+1个比特的取值为1，则第一集合中的第k+1个时间单元属于资源池；其中，k′表示比特位图中的比特位的索引，k表示第一集合中的时间单元的索引，k和k′均为大于或等于0的整数，且k基于k′与L确定，或者k和k′具有关联关系，L表示比特位图的长度。
需要说明的是，上述k′表示比特位图中的比特位的索引，在一些场景中，比特位的索引可以从0开始编号，相应地，比特位图中的第1个比特对应的索引可以为0。另外，上述k表示第一集合中的时间单元(例如，第一时间单元)的索引，在一些场景中，时间单元的索引可以从0开始编号，相应地，第一集合中的第1个时间单元对应的索引可以为0。
当然，在本申请实施例中，上述比特位图的索引k′和/或第一集合中时间单元的索引k也可以从1开始索引，相应地，如果比特位图中的第k′个比特的取值为1，则第一集合中的第k个时间单元属于资源池，其中，k和k′均为大于或等于0的整数，且k基于k′与L确定，或者k和k′具有关联关系，L表示比特位图的长度。
本申请实施例对k的确定方式(或者说，对k和k′的关联关系)不作限定，例如，k可以通过公式k′＝k mod L确定，其中，mod表示求余运算。
需要说明的是，上述k的取值小于第一集合中包含的第一时间单元的数量最大值。例如，k的取值范围可以表示为：0≤k<10240×2μ/M1-NS-SSB-NnonSL-Nreserved。
在一些实现方式中，第一集合中的第一时间单元 满足如下条件时属于资源池：如果bk′＝1，k′＝k mod L，则第一时间单元属于资源池，其中，bk′表示第一信息对应的比特位图中的第k′+1个比特。
在一些实现方式中，将基于第一信息从第一集合中确定的属于资源池的时间单元的集合记为第三集合，将通过上述方式确定的属于资源池中的第一时间单元在第三集合中按照索引从低到高的顺序重新进行顺序索引，第三集合中的第一时间单元表示为i的取值为{0,1,…,T′max-1}，T′max表示第三集合中包括的第一时间单元的数量。
另外，还需要说明的是，本申请实施例对比特位的取值与时域资源属于资源池之间的对应关系不作限定。在一些实现方式中，若比特位的取值为1，可以表示对应的时间单元属于资源池，相反地，若比特位的取值为0，可以表示对应的时间单元不属于资源池。在另一些实现方式中，若比特位的取值为0，可以表示对应的时间单元属于资源池，相反地，若比特位的取值为1，可以表示对应的时间单元不属于资源池。
如上文的介绍可知，在本申请实施例中，可用于传输S-SSB的时间单元、可用于传输PSCCH/PSSCH的时间单元以及第一信息指示的时间单元均可以为第一时间单元。相应地，为了提高SFN周期内时隙 的利用率，在一些实现方式中，SFN周期内包括的时隙数量可以为第一时间单元包括的时隙数量的整数倍，或者说，第一终端设备不期望一个SFN周期内包括的时隙数量(例如，10240×2μ)不能被M1整除，又或者说，第一终端设备期望一个SFN周期内包括的时隙数量为第一时间单元包括的时隙数量的整数倍。当然，在本申请实施例中，SFN周期内包括的时隙数量可以不为第一时间单元包括的时隙数量的整数倍。
实施例2-2：基于第二时间单元传输S-SSB。
在一些场景中，SFN周期内不能用于侧行传输的时域资源(又称“第二时域资源”)，用于传输S-SSB的时域资源(又称“第一时域资源”)以及预留的时域资源(又称“第三时域资源”)中的一种或多种不属于资源池，因此，在指示属于资源池的时域资源时，还需要考虑上述一种或多种资源。
换句话说，假设属于资源池的时域资源从第一集合中确定，其中，第一集合包括多个第一时间单元，则第一集合基于以下中的一种或多种确定：第一时域资源、第二时域资源、以及第三时域资源。
在一些实现方式中，如果一个时隙中的可用于侧行传输的第一个符号为一个时隙中的第一个符号，则SFN周期内的不能用于侧行传输的时隙的数量的取值为0，即NnonSL＝0。
需要说明的是，上述预留的时域资源例如可以是预留的时间单元，或者预留时隙。当然，在本申请实施例中，上述预留的时域资源还可以包括预留的时域符号。本申请实施例对此不作限定。
为了便于介绍，下文将第一时域资源包括的时域资源的数量表示为“NS-SSB”，将第二时域资源包括的时域资源的数量表示为“NnonSL”，将第三时域资源包括的时域资源的数量表示为“Nreserved”。需要说明的是，在本申请实施例中，上述三种时域资源所包含的时域资源的粒度可以相同也可以不同。另外，在本申请实施例中，上述NnonSL、NS-SSB以及Nreserved可以为大于或等于0的正整数。
例如，第一时域资源包括的时域资源可以以时隙为粒度，相应地，NS-SSB表示第一时域资源包括的时隙的数量。当然，第一时域资源包括的时域资源可以以第二时间单元为粒度，相应地，NS-SSB表示第一时域资源包括的第二时间单元的数量。第一时域资源包括的时域资源可以以第一时间单元为粒度，相应地，NS-SSB表示第一时域资源包括的第一时间单元的数量。
又例如，第二时域资源包括的时域资源可以以时隙为粒度，相应地，NnonS表示第二时域资源包括的时隙的数量。当然，第二时域资源包括的时域资源可以以第二时间单元为粒度，相应地，NnonSL表示第二时域资源包括的第二时间单元的数量。第二时域资源包括的时域资源可以以第一时间单元为粒度，相应地，NnonSL表示第二时域资源包括的第一时间单元的数量。
又例如，第三时域资源包括的时域资源可以以时隙为粒度，相应地，Nreserved表示第三时域资源包括的时隙的数量。当然，第三时域资源包括的时域资源可以以第二时间单元为粒度，相应地，Nreserved表示第三时域资源包括的第二时间单元的数量。第三时域资源包括的时域资源可以以第一时间单元为粒度，相应地，Nreserved表示第三时域资源包括的第一时间单元的数量。
如上文介绍，上述第一时域资源、第二时域资源、以及第三时域资源中的一种或多种资源不属于资源池，因此，在确定第一集合时可以将上述一种或多种时域资源从一个SFN周期包括的时域资源中排除。
在一些实现方式中，第一集合中包括的第一时间单元的数量或时隙数量可以基于以下信息中的一种或多种确定：一个SFN周期包括的时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的时域资源的数量，第二时域资源包括的时域资源的数量，第三时域资源包括的时域资源的数量。例如，第一集合中包括的第一时间单元的数量或时隙数量可以基于以下信息中的一种或多种确定：一个SFN周期包括的时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的时隙数量，第二时域资源包括的时隙数量，第三时域资源包括的时隙数量。

在一些实现方式中，一个SFN周期包括的时域资源对应的第一时间单元的数量为10240×2μ/M1，索引范围为[0，10240×2μ/M1-1]。若NS-SSB表示第一时域资源对应的时隙的数量，NnonSL表示第二时域资源对应的时隙的数量，Nreserved表示第三时域资源对应的第一时间单元的数量，则第一集合中包括的第一时间单元的数量为(10240×2μ-NS-SSB-NnonSL)/M1-Nreserved。
在一些实现方式中，一个SFN周期包括的时域资源对应的第一时间单元的数量为10240×2μ/M1， 索引范围为[0，10240×2μ/M1-1]。若NS-SSB表示第一时域资源对应的时隙的数量，NnonSL表示第二时域资源对应的第一时间单元的数量，Nreserved表示第三时域资源对应的第一时间单元的数量，则第一集合中包括的第一时间单元的数量为(10240×2μ-NS-SSB)/M1-NnonSL-Nreserved。
在一些实现方式中，一个SFN周期包括的时域资源对应的第一时间单元的数量为10240×2μ/M1，索引范围为[0，10240×2μ/M1-1]。若NS-SSB表示第一时域资源对应的时隙的数量，NnonSL表示第二时域资源对应的时隙的数量，Nreserved表示第三时域资源对应的时隙的数量，则第一集合中包括的第一时间单元的数量为(10240×2μ-NS-SSB-NnonSL-Nreserved)/M1。
在一些实现方式中，第一集合中包括的第一时间单元的数量可以基于第二数量确定，第二数量等于(10240×2μ-NS-SSB-NnonSL)/M1-Nreserved。
在一些实现方式中，第一集合中包括的第一时间单元的数量可以基于第四数量确定，第四数量等于(10240×2μ-NS-SS)/M1-NnonSL-Nreserved。
在一些实现方式中，第一集合中包括的第一时间单元的数量可以基于第五数量确定，第五数量等于(10240×2μ-NS-SSB-NnonSL-Nreserved)/M1。
上述μ表示基于侧行子载波间隔确定的参数(μ的取值例如可以参考表5的相关介绍)。
上述NS-SSB表示基于第一时域资源包括的第二时间单元的数量确定的参数。在一些实现方式中，NS-SSB可以等于第一时域资源包括的时隙的数量。在一些实现方式中，第一时域资源包括的时隙的数量可以根据第一时域资源包括的第二时间单元的数量确定，例如，NS-SSB可以等于第一时域资源包括的第二时间单元的数量与第二时间单元包括的时隙的数量(即M2)的乘积。本申请实施例对计算NS-SSB的方式不作具体限定。
上述NnonSL表示基于第二时域资源包括的时域资源的数量确定的参数，以时域资源为时隙为例，NnonSL表示基于第二时域资源包括的时隙的数量确定的参数。在一些实现方式中，NnonSL可以等于第二时域资源包括的时隙的数量。在一些实现方式中，NnonSL可以等于第二时域资源包括的第一时间单元的数量。当然，在本申请实施例中，NnonSL还可以是通过对第二时域资源包括的时域资源的数量进行计算得到的，例如，可以通过对第二时域资源包括的第一时间单元的数量乘以第一时间单元包括的时隙数量(即M1)得到NnonSL。又例如，可以通过对第二时域资源包括的第二时间单元的数量乘以第二时间单元包括的时隙数量(即M2)得到NnonSL。本申请实施例对计算NnonSL的方式不作具体限定。
上述Nreserved表示基于第三时域资源包括的时域资源的数量确定的参数。以时域资源为第一时间单元为例，Nreserved表示基于第三时域资源包括的第一时间单元的数量确定的参数。在一些实现方式中，Nreserved可以等于第三时域资源包括的第一时间单元的数量。在一些实现方式中，Nreserved可以等于第三时域资源包括的时隙数量。当然，在本申请实施例中，Nreserved还可以是通过对第三时域资源包括的时域资源的数量进行计算得到的，例如，可以通过对第三时域资源包括的时隙的数量除以第一时间单元包括的时隙数量(即M1)得到Nreserved。本申请实施例对计算Nreserved的方式不作具体限定。
在一些实现方式中，一个SFN周期包括的时域资源对应的时隙数量为10240×2μ，索引范围为[0,10240×2μ-1]。若NS-SSB表示第一时域资源对应的时隙数量，NnonSL表示第二时域资源对应的时隙数量，Nreserved表示第三时域资源对应的时隙数量，则第一集合中包括的时隙数量为10240×2μ-NS-SSB-NnonSL-Nreserved，第一集合中包括的第一时间单元的数量为(10240×2μ-NS-SSB-NnonSL-Nreserved)/M1。
在一些实现方式中，一个SFN周期包括的时域资源对应的时隙数量为10240×2μ，索引范围为[0,10240×2μ-1]。若NS-SSB表示第一时域资源对应的时隙数量，NnonSL表示第二时域资源对应的第一时间单元的数量，Nreserved表示第三时域资源对应的第一时间单元的数量，则第一集合中包括的第一时间单元的数量为(10240×2μ-NS-SSB)/M1-NnonSL-Nreserved。
在一些实现方式中，一个SFN周期包括的时域资源对应的时隙数量为10240×2μ，索引范围为[0,10240×2μ-1]。若NS-SSB表示第一时域资源对应的时隙数量，NnonSL表示第二时域资源对应的时隙数量，Nreserved表示第三时域资源对应的第一时间单元的数量，则第一集合中包括的第一时间单元的数量为(10240×2μ-NS-SSB-NnonSL)/M1-Nreserved。需要说明的是，本申请实施例的方案以第一集合中包括的第一时间单元的数量基于第二数量确定为例进行说明，本申请实施例的方案同样适用于第一集合中包括的第一时间单元的数量基于第四数量或第五数量确定的情况。
在一些实现方式中，第一集合用于表示一个SFN周期内可能属于资源池的时间单元集合。
在一些实现方式中，第一集合(或者说，一个SFN周期内可能属于资源池的时间单元集合)可以表示为：其中，表示第一集合中的第i个第一时间单元，Tmax可以是基于一个SFN周期包括的时域资源排除第一时域资源、第二时域资源、 以及第三时域资源之后剩余的时域资源的数量确定的。例如，Tmax可以是等于一个SFN周期包括的时隙的数量减第一时域资源对应的时隙的数量、第二时域资源对应的时隙的数量之后的剩余时隙对应的第一时间单元的数量再减去第三时域资源对应的第一时间单元的数量。

上文介绍了本申请实施例中第一集合的确定方式，下文介绍本申请实施例中第三时域资源包括的第一时间单元的数量的确定方式，以及第三时域资源的确定方式。
在一些实现方式中，第三时域资源包括的时域资源的数量基于以下中的一种或多种确定：第一时域资源包括的时域资源的数量；第二时域资源包括的时域资源的数量；以及第一信息对应的比特数量。例如，第三时域资源包括的时域资源的数量基于以下中的一种或多种确定：第一时域资源包括的时隙数量；第二时域资源包括的时隙数量；以及第一信息对应的比特数量。在另一些实现方式中，上述第三时域资源包括的时域资源的数量基于以下中的一种或多种确定：一个SFN周期包括的第一时间单元的数量或时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的时域资源的数量；第二时域资源包括的时域资源的数量；以及第一信息对应的比特数量。例如，上述第三时域资源包括的时域资源的数量基于以下中的一种或多种确定：一个SFN周期包括的第一时间单元的数量或时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的时隙数量；第二时域资源包括的时隙数量；以及第一信息对应的比特数量。
如上文介绍，在本申请实例中，可以基于第二时间单元传输S-SSB，相应地，第一时域资源包括的时域资源的数量例如可以包括第一时域资源包括的第二时间单元的数量。当然，在本申请实施例中，第一时域资源包括的时域资源的数量例如还可以包括第一时域资源包括的时隙的数量。
在一些实现方式中，第二时域资源包括的时域资源的数量，可以包括第二时域资源包括的时隙的数量。或者，第二时域资源包括的时域资源的数量还可以包括第二时域资源包括的第一时间单元的数量。或者，第二时域资源包括的时域资源的数量还可以包括第二时域资源包括的第二时间单元的数量。本申请实施例对此不作限定。
以第一信息用于指示比特位图为例，上述第一信息对应的比特数量，可以理解为是比特位图包括的比特数量。
在一些实现方式中，第三时域资源包括的时域资源的数量满足：Nreserved＝(10240×2μ-NS-S-NnonSL)/M1 mod L，其中，L表示第一信息对应的比特数量，其余参数可以参见上文的介绍。也即是说，第三时域资源包括的时域资源的数量的设置使得一个SFN周期包括的时域资源的数量减去第一时域资源包括的时域资源的数量NS-SSB、第二时域资源包括的时域资源的数量NnonSL、以及第三时域资源包括的时域资源的数量Nreserved后，剩余的时域资源对应的第一时间单元的数量能够被第一信息对应的比特数量整除。

在一些实现方式中，上述第三时域资源基于以下中的一种或多种从第二集合中确定：一个SFN周期包括的第一时间单元的数量或时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的时域资源的数量；第二时域资源包括的时域资源的数量；第三时域资源包括的时域资源的数量。例如，上述第三时域资源基于以下中的一种或多种从第二集合中确定：一个SFN周期包括的第一时间单元的数量或时隙数量，第一时间单元包括的时隙数量，第一时域资源包括的时隙数量；第二时域资源包括的时隙数量；第三时域资源包括的时隙数量。
上述第二集合中的时间单元为SFN周期包含的时域资源中的目标时域资源对应的时间单元，目标时域资源为SFN周期包含的时域资源中的除第一时域资源和第二时域资源之后剩余的时域资源。在一些实现方式中，第二集合可以表示为

上文介绍了本申请实施例中第三时域资源的确定方式，下文介绍本申请实施例中从第一集合中指 示属于资源池的时间单元的方法。
在一些实现方式中，第一信息为比特位图，如果比特位图中的第k′+1个比特的取值为1，则第一集合中的第k+1个时间单元属于资源池；其中，k′表示比特位图中的比特位的索引，k表示第一集合中的时间单元的索引，k和k′均为大于或等于0的整数，且k基于k′与L确定，或者k和k′具有关联关系，L表示比特位图的长度。
需要说明的是，上述k′表示比特位图中的比特位的索引，在一些场景中，比特位的索引可以从0开始编号，相应地，比特位图中的第1个比特对应的索引可以为0。另外，上述k表示第一集合中的时间单元(例如，第一时间单元)的索引，在一些场景中，时间单元的索引可以从0开始编号，相应地，第一集合中的第1个时间单元对应的索引可以为0。
当然，在本申请实施例中，上述比特位图的索引k′和/或第一集合中时间单元的索引k也可以从1开始索引，相应地，如果比特位图中的第k′个比特的取值为1，则第一集合中的第k个时间单元属于资源池，其中，k和k′均为大于或等于0的整数，且k基于k′与L确定，或者k和k′具有关联关系，L表示比特位图的长度。
本申请实施例对k的确定方式(或者说，对k和k′的关联关系)不作限定，例如，k可以通过公式k′＝k mod L确定，其中，mod表示求余运算。
需要说明的是，上述k的取值小于第一集合中包含的第一时间单元的数量最大值。例如，k的取值范围可以表示为：0≤k<(10240×2μ-NS-SSB-NnonSL)/M1-Nreserved。
在一些实现方式中，第一集合中的第一时间单元 满足如下条件时属于资源池：如果bk′＝1，k′＝k mod L，则第一时间单元属于资源池，其中，bk′表示第一信息对应的比特位图中的第k′+1个比特。
在一些实现方式中，将基于第一信息从第一集合中确定的属于资源池的时间单元的集合记为第三集合，将通过上述方式确定的属于资源池中的第一时间单元在第三集合中按照索引从低到高的顺序重新进行顺序索引，第三集合中的第一时间单元表示为i的取值为{0,1,…,T′max-1}，T′max表示第三集合中包括的第一时间单元的数量。
在一些场景中，在SFN周期内相邻的两个传输S-SSB的第二时间单元之间的时域资源可以基于第一信息指示是否属于资源池，其中，如前文介绍第一信息以第一时间单元为粒度指示，因此，为了匹配第一信息的指示方式，在一些实现方式中，上述SFN周期内相邻的两个传输S-SSB的第二时间单元之间包括的时隙数量为第一时间单元包括的时隙数量的整数倍。或者说，第一终端设备期望SFN周期内相邻的两个传输S-SSB的第二时间单元之间包括的时隙数量为第一时间单元包括的时隙数量的整数倍，又或者说，第一终端设备不期望SFN周期内相邻的两个传输S-SSB的第二时间单元之间包括的时隙数量不为第一时间单元包括的时隙数量的整数倍。
在一些实现方式中，一个SFN周期内相邻的两个传输S-SSB的第二时间单元之间包括的时隙数量与目标数量的差值为第一时间单元包括的时隙数量的整数倍，其中，目标数量为相邻的两个传输S-SSB的第二时间单元之间包括的第二时域资源的时域资源数量。也即是说，SFN周期内相邻的两个传输S-SSB的第二时间单元之间除了第二时域资源之外的剩余时隙的数量为第一时间单元包括的时隙数量的整数倍，有助于匹配第一信息的资源指示粒度。或者说，第一终端设备期望上述差值为第一时间单元包括的时隙数量的整数倍。又或者说，第一终端设备不期望上述差值不为第一时间单元包括的时隙数量的整数倍。
在一些实现方式中，SFN周期内包括的时隙数减去第一时域资源包括的时隙数量以及第二时域资源包括的时隙数量后剩余的时隙数量为第一时间单元包括的时隙数量的整数倍，有助于减少预留的时域资源的数量。或者说，第一终端设备期望上述剩余的时隙数量为第一时间单元包括的时隙数量的整数倍。又或者说，第一终端设备不期望上述剩余的时隙数量不为第一时间单元包括的时隙数量的整数倍。
如上文关于实施例2.1以及实施例2.2的方案中，一个SFN周期内除了第一时域资源、第二时域资源以及第三时域资源之外，剩余的时域资源才可能属于资源池，因此，为了便于以第一时间单元为粒度指示剩余的时域资源是否属于资源池，在一些实现方式中，上述SFN周期内除了第一时域资源、第二时域资源以及第三时域资源之外的剩余的时隙数量为第一时间单元包括的时隙数量的整数倍，或者说，第一终端设备期望SFN周期内除了第一时域资源、第二时域资源以及第三时域资源之外的剩余的时隙数量为第一时间单元包括的时隙数量的整数倍，又或者说，第一终端设备不期望SFN周期内除了第一时域资源、第二时域资源以及第三时域资源之外的剩余的时隙数量不为第一时间单元包括的时隙数量的整数倍。
在一些实现方式中，SFN周期内包括的时隙数量减去第一时域资源包括的时隙数量、第二时域资源包括的时隙数量以及第三时域资源包括的时隙数量后剩余的时隙数量为第一信息对应的比特数量的整 数倍，有助于匹配第一信息的指示方式。或者说，第一终端设备期望上述剩余的时隙数量为第一信息对应的比特数量的整数倍，又或者说，第一终端设备不期望上述剩余的时隙数量不为第一信息对应的比特数量的整数倍。
