具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
为了便于理解，首先介绍本申请涉及的术语。
终端设备与终端设备之间通过侧行链路sidelink通信。其中，sidelink包括物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)和物理侧行共享信道(Physical Sidelink Share Channel，PSSCH)。PSCCH中的侧行控制信息(sidelink control information，SCI)可以指示接收PSSCH所需的信息，如PSSCH信道资源以及传输参数等。PSSCH用于承载sidelink通信的数据。
物理资源块(Physical Resource Block，PRB)，用来描述实际物理资源的分配情况。
交错资源块(Interlaced Resource block，IRB)，指同一个交错资源块索引中连续的两个交错资源块间相隔固定数量的资源块。举例来说，两个交错资源块间相隔M个资源块，则索引index为m的IRB，其包括的物理资源块(PhysicalResourceBlock，PRB)为{m，m+M，2M+m，3M+m，……}，其中m∈{0，1，…，M-1}。在新空口非授权(new radio unlicensed，NR-U)系统中，针对15kHz和30kHz两种子载波间隔(sub carrier space，SCS)分别定义了IRB结构，15kHz，M＝10，有10个IRBindex，30kHzM＝5，有5个IRBindex。也就是说，SCS＝30khz,M＝5时，共有5个梳尺索引，对于第一个1个IRB索引，即IRB索引为0，该交错索引中含有的交错资源块对应的PRB为{0,5,10,15,20,25,30,35,40,45}。
为了更好的理解本申请实施例公开的反馈信息的发送/接收方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1，图1为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。还需要说明的是，本申请实施例中的侧链路还可以称为侧行链路或直通链路。
本申请实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile  phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
在侧链路通信中，存在4种侧链路传输模式。侧链路传输模式1和侧链路传输模式2用于终端设备直通(device-to-device，D2D)通信。侧链路传输模式3和侧链路传输模式4用于V2X通信。当采用侧链路传输模式3时，资源分配由网络设备101调度。具体的，网络设备101可以将资源分配信息发送给终端设备102，然后由该终端设备102向另一终端设备分配资源，以使得该另一终端设备可以通过分配到的资源向网络设备101发送信息。在V2X通信中，可以将信号较好或者可靠性较高的终端设备作为终端设备102。本申请实施例中提及的第一终端设备可以指该终端设备102，第二终端设备可以指该另一终端设备。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请所提供的一种反馈信息的发送/接收方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种反馈信息的发送方法的流程示意图。该方法由终端设备执行，如图2所示，该方法可以包括但不限于如下步骤：

其中，N为正整数。
可选地，终端设备可以在非授权频谱(unlicensedspectrum)或共享频谱(sharedspectrum)上进行侧行链路(sidelink，SL)。

可选地，终端设备可以获取用于PSCCH和/或PSSCH的侧行资源池，其中，该侧行资源池中包括多个交错资源块(Interlaced Resource block，IRB)，本申请实施例中，终端设备可以使用其中一个第一IRB对N个反馈信息进行反馈，即可以将N个反馈信息映射到该第一IRB上不同的频域资源上，通过第一IRB上不同的频域资源对N个反馈信息进行发送。在一些实施例中可以基于IRB的频域位置和/或IRB的索引号，从终端设备对应的多个IRB中，确定出第一IRB。
例如，第一IRB上的频域资源为PRB，第一IRB中可以包括M个PRB，M为大于或者等于1的正整数。也就是说，终端设备可以将N个反馈信息映射到第一IRB中的M个PRB进行发送。
本申请实施例中在终端设备进行SL发送时，通过一个第一交错资源块IRB进行不同的N个反馈信息的发送。本申请实施例中，当终端设备接收到多个PSCCH/PSSCH传输的情况下，可以将这些PSCCH/PSSCH传输对应的反馈信息映射到同一个IRB上进行传输，不再将多个反馈信息在多个IRB上 进行传输，可以避免干扰提供系统的可靠性和传输效率。
请参见图3，图3是本申请实施例提供的一种反馈信息的发送方法的流程示意图。该方法由终端设备执行，如图3所示，该方法可以包括但不限于如下步骤：
S31，当终端设备进行SL发送时，确定属于第一IRB的M个PRB和N个反馈信息之间的对应关系。
其中，M为指示所述第一IRB中包括的PRB的数目，M为正整数。
可选地，第一IRB中可以包括M个PRB，为了实现在第一IRB中传输N个反馈信息，本申请实施例中，属于第一IRB的M个PRB和N个反馈信息之间存在对应关系。可选地，终端设备可以通过网络指示或者网络配置确定该对应关系，或基于预定义映射规则或预配置映射规则，确定第一IRB中包括的M个PRB与N个反馈信息之间的映射关系。
本申请实施例中，上述对应关系可以指示出每个反馈信息所对应的PRB，例如，反馈信息I i对应PRB m，反馈信息I j对应PRB n和PRB l，即对应关系可以指示用于传输任一反馈信息所需要占用的一个或多个PRB。可选地，对应关系可以为一个列表，该列表中包括N个反馈信息和第一IRB中M个PRB之间的映射关系。
S32，根据对应关系确定属于第一IRB的PRB m上传输的第一信息。
其中，PRB m为第一IRB中包括的M个PRB中一个PRB，m的取值为1至M。
需要说明的是，第一信息可以为属于N个反馈信息中的一个反馈信息；第一信息也可以非N个反馈信息中反馈信息，即第一信息也可为不指示N个反馈信息中任何反馈信息，即可以为除N个反馈信息之外的其他信息或信号。
可选地，在第一信息未指示N个反馈信息中任一反馈信息的情况下，在PRB m上传输的第一信息为除N个反馈信息之外的其他信息或信号。可选地，第一信息可以为预定义的信号，或者为预配置的信号，或者为网络设备通过下行信令配置的信号，也就是说，上述预定义、预配置或者网络设备下行配置的信号，并未指示N个反馈信息中任一反馈信息。
可选地，终端设备可以根据基序列和/或循环移位值；例如，基序列和/或循环移位值可以通过预定义、预配置或者通过网络设备下行信令配置。进一步地，基于基序列和/或循环移位值确定在PRB m上传输的该第一信息。
S33，在PRB m上传输第一信息。
可选地，在PRB m上确定传输的第一信息为N个反馈信息中一个反馈信息时，可以直接在PRB m上传输该反馈信息。
可选地，在PRB m上确定传输的第一信息非N个反馈信息中一个反馈信息时，即第一信息为预定义或者为预配置或者网络设备通过下行信令配置的信号时，可以直接在PRB m上传输该信号。
可选地，在PRB m上确定传输的第一信息非N个反馈信息中一个反馈信息时，可以使用N个反馈信息中一个特定反馈信息，如优先级最高的反馈信息替换到第一信息，在该PRB m上传输该优先级最高的反馈信息。
可选地，基于基序列和/或循环移位值确定在PRB m上传输的信号。
可选地，在PRB m上使用基序列的不同循环移位值传输第一信息。
本申请实施例中，当终端设备接收到多个PSCCH/PSSCH传输的情况下，可以将这些PSCCH/PSSCH传输对应的反馈信息映射到同一个IRB上进行传输，不再将多个反馈信息在多个IRB上进行传输，可 以避免干扰提供系统的可靠性和传输效率。
请参见图4，图4是本申请实施例提供的一种反馈信息的发送方法的流程示意图。该方法由终端设备执行，如图4所示，该方法可以包括但不限于如下步骤：
S41，当终端设备进行SL发送时，确定时频位置集合中N个时频位置与第一IRB中M个PRB之间的对应关系。
其中，时频位置集合中包括多个时频位置，其中，时域位置可以包括，时频位置包括时域位置、频域位置和时频起始位置中至少一个。
可选地，为使用第一IRB进行传输的反馈信息对应的PSCCH/PSSCH传输的可能时域位置和/或频域位置的集合。例如，第一IRB对应的PSCCH/PSSCH的时间频域和频域位置形成的集合即为时频位置集合：{{时域位置1，频域位置1}，{时域位置2，频域位置2}…,{时域位置N，频域位置N}}；再例如，第一IRB对应的PSCCH/PSSCH的时域位置形成的集合即为时频位置集合：{时域位置1，时域位置2，…,时域位置N}；又例如，第一IRB对应的PSCCH/PSSCH的频域位置形成的集合即为时频位置集合：{频域位置1，频域位置2，…,频域位置N}。
可选地，时频位置集合为使用第一IRB进行传输的反馈信息对应的PSCCH/PSSCH传输的可能时频起始位置的集合。例如，第一IRB对应的PSCCH/PSSCH的时域起始位置和频域起始位置形成的集合即为时频位置集合：{{时域起始位置1，频域起始位置1}，{时域起始位置2，频域起始位置2}…,{时域起始位置N，频域起始位置N}}；再例如，再例如，第一IRB对应的PSCCH/PSSCH的时域起始位置形成的集合即为时频位置集合：{时域起始位置1，时域起始位置2，…,时域起始位置N}；又例如，第一IRB对应的PSCCH/PSSCH的频域起始位置形成的集合即为时频位置集合：{频域起始位置1，频域起始位置2，…,频域起始位置N}。
可选地，时频位置集合为侧行资源池中反馈时间窗口内的时频资源位置的集合；其中，反馈时间窗口的起始和结束时间根据第一IRB所在的时间位置确定。例如，第一IRB所处的时隙(slot)为slot#n，那么能够使用该第一IRB进行反馈信息传输的PSCCH/PSSCH只能处于时间窗口[n-X，n-Y]之内，该时间窗口内的时频资源位置集合即为时频位置集合。其中，X和Y的取值根据预定义和/或(预)配置确定。
作为一种可能的实现方式，N个时频位置与第一IRB内的M个PRB之间的对应关系的确定包括：
按照第一设定顺序，将第一IRB内的M个PRB划分为N个正交的PRB子集。例如，例如，将M个PRB按照频域有低到高的顺序划分为N个正交的PRB子集，或者M个PRB按照频域有高到低的顺序划分为N个正交的PRB子集。
进一步地，按照第二设定顺序，将时频位置集合中时频位置进行排序。例如，可以对时频位置集合中每个时频位置按照时域顺序进行排序或者按照频域顺序进行排序。比方可以时域上按照从早到位的顺序对时域位置进行排序，或者案在频域上按照频域从低到高的顺序对时频位置进行排序。
在排序后，对排序后的时频位置与PRB子集进行一对一映射，得到N个时频位置与第一IRB内M个PRB之间的对应关系。
需要说明的是，时域位置为PSCCH/PSSCH传输所在的时间单元。其中，时间单元可以为以下一种情况：正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)符号(symbol)、子时隙(subslot)、时隙(slot)或者子帧(subframe)。
可选地，频域位置为PSCCH/PSSCH传输使用的最低频率位置的PRB、IRB或子信道。

可选地，确定反馈信息I i对应的PSCCH和/或PSSCH传输占用的时频位置，并基于反馈信息I i对应的时频位置，查询上述对应关系，可以从中确定时频位置所对应的PRB m，即为反馈信息I i所对应的PRB m。
本申请实施例中，对应关系为时频位置与PRB子集之间的对应关系，可以基于时频位置与PRB子集之间的对应关系确定反馈信息I i所对应的PRB m。可选地，确定反馈信息I i对应的PSCCH和/或PSSCH传输占用的时频位置从上述对应关系中确定反馈信息I i对应的时频位置所关联的PRB子集。进一步地，将反馈信息I i对应的时频位置所关联的PRB子集中包括的PRB，确定为反馈信息I i对应的PRB m。
S43，在PRB m上传输反馈信息I i。
关于步骤S43的具体实现方式可参见上述实施例中相关内容的记载，此处不再赘述。
本申请实施例中，当终端设备接收到多个PSCCH/PSSCH传输的情况下，可以将这些PSCCH/PSSCH传输对应的反馈信息映射到同一个IRB上进行传输，不再将多个反馈信息在多个IRB上进行传输，可以避免干扰提供系统的可靠性和传输效率。

S51，当终端设备进行SL发送时，确定属于第一IRB的M个PRB和N个反馈信息之间的对应关系。
S52，根据对应关系确定属于第一IRB的PRB m上传输的第一信息。
关于步骤S51～步骤S52的具体实现方式，可采用本申请实施例中任一可能的实现方式，此处不再赘述。
S53，当PRB m上对应的第一信息非N个反馈信息中的反馈信息，确定N个反馈信息中优先级最高的反馈信息。
N个反馈信息中的反馈信息配置有各自的优先级，不同反馈信息之间的优先级可能相同或不同。本申请实施例中，当PRB m上对应的第一信息非N个反馈信息中的反馈信息，即第一信息为除N个反馈信息之前的其他信息或信号，可以基于N个反馈信息中反馈信息的优先级信息，从N个反馈信息中确定出优先级最高的反馈信息。
S54，确定优先级最高的反馈信息为PRB m上传输的反馈信息，并在PRB m上传输优先级最高的反馈信息。
可选地，N个反馈信息中可能存在两个或两个以上优先级最高的反馈信息，此种情况下，可以通过根据约定或者指示，从两个或两个以上优先级最高的反馈信息中确定出一个作为PRB m上传输的反馈信息。
本申请实施例中，在第一IRB的M个PRB和N个反馈信息之间的对应关系，确定出PRB m上对应的第一信息未属于N个反馈信息，可以重新为PRB m映射N个反馈信息中优先级最高的反馈信息，提高优先级最高的反馈信息的传输成功率。
请参见图6，图6是本申请实施例提供的一种反馈信息的发送方法的流程示意图。该方法由终端设备执行，如图6所示，该方法可以包括但不限于如下步骤：

S62，根据对应关系确定属于第一IRB的PRB m上传输的第一信息。
S63，当PRB m上对应的第一信息非N个反馈信息中的反馈信息，确定N个反馈信息中优先级最高的反馈信息。
S64，确定优先级最高的反馈信息为PRB m上传输的反馈信息。
关于步骤S61～步骤S64的具体实现方式可参见上述实施例中相关内容的记载，此处不再赘述。
S65，确定优先级最高的反馈信息为第一IRB中PRB n上传输的反馈信息，则在PRB m和PRB n上分别传输优先级最高的反馈信息。
本申请实施例中，终端设备可以基于属于第一IRB的M个PRB和N个反馈信息之间的对应关系，确定出优先级最高反馈信息为反馈信息I k对应的PRB n。可选地，在PRB m和PRB n上传输的物理层传输参数相同或不同；其中，物理层传输参数包括基序列(Sequence，SN)、循环移位(Cyclic Shift，CS)值和功率中至少一个。
也就是说，优先级最高反馈信息为反馈信息I k，在PRB m上传输时使用的物理层传输参数，如基序列、循环移位值和功率等，与反馈信息I k在基于对应关系确定出PRB n上传输使用的物理层传输参数相同。或者，反馈信息I k在PRB m上传输时使用的物理层传输参数，如基序列、循环移位值和功率等，与反馈信息I k在对应关系确定出PRB n上传输使用的物理层传输参数不同；
例如，可以定义不重合的CS值集合1{CS 1,CS 2,…,C m,…}和集合2{CS 1’,CS 2’,…，C m’,…}，且两个集合中的元素一一对应；对于反馈信息I k其在PRB n上发送时使用CS集合1中的CSm，而在PRB n上发送时使用CS集合2中对应的C m’。
再例如，对于反馈信息I k其在PRB n上发送时使用基序列SN 1，而在PRB n上发送时使用基序列SN 2。可选地，两个基序列不同。
本申请实施例中，可以在两个PRB上传输N个反馈信息中优先级最高的反馈信息，提高优先级最高的反馈信息的传输成功率。

S72，根据对应关系和N个反馈信息对应的优先级信息，确定在PRB m上传输的反馈信息。
可选地，基于对应关系，确定PRB m对应于N个反馈信息中的反馈信息I i。关于基于对应关系，确定PRB m对应于N个反馈信息中的反馈信息I i的过程，可参见上述实施例中相关内容的记载，此处不再赘述。
进一步地，确定除了反馈信息I i之外的N个反馈信息中的其他反馈信息中的最高优先级的反馈信息I j。基于反馈信息I i对应的优先级和反馈信息I j的优先级，进一步确定该PRB m上传输的反馈信息。可选地，将反馈信息I i对应的优先级和反馈信息I j的优先级进行比较，确定反馈信息I i对应的优先级不低于反馈信息I j的优先级设定个级别，则确定反馈信息I i为在PRB m上传输的反馈信息。
可选地，确定反馈信息I i对应的优先级高于反馈信息I j的优先级，或者，反馈信息I i对应的优先级虽然低于反馈信息I j的优先级，但是两者的优先级差值大于设定个数，此种情况下确定反馈信息I j为在PRB m上传输的反馈信息。
例如，反馈信息I i的优先级为p i，反馈信息I j的优先级为p j，若p i≤p j+X，其中在数值越小优先级越高的情况，值越大优先级越低，在PRB m传输反馈信息I j；否则p i＞p j+X，在PRB m传输反馈信息I i； 其中，X的取值可以是预定义或者预配置或者网络设备通过下行控制信令配置和/或指示。
S73，在PRB m上传输反馈信息I i或I j。
