Description

副链路反馈资源配置方法、装置及设备
交叉引用
本发明要求在2020年07月29日提交中国专利局、申请号为202010747222.5、发明名称为“副链路反馈资源配置方法、装置及设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请涉及通信领域，尤其涉及一种副链路反馈资源配置方法、装置及设备。
背景技术
目前，长期演进(Long Term Evolution，LTE)系统支持副链路(Sidelink，SL，也可称之为侧链路、旁链路或边链路等)传输。SL用于用户设备(User Equipment，UE，也可称为终端设备)之间不通过网络侧设备直接进行数据传输。可用于LTE系统所不支持的6GHz以上工作频段、支持更大的工作带宽的新空口(New Radio，NR)系统也支持UE之间直接通信的Sidelink接口通信。
其中，UE通过物理副链路控制信道(Physical Sidelink Control Channel，PSCCH)发送副链路控制信息(Sidelink Control Information，SCI)，调度物理副链路共享信道(Physical Sidelink Shared Channel，PSSCH)的传输以发送数据。SCI中可以指示传输资源，并预留这些资源用于未来的传输。另外，物理副链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)用于反馈Sidelink混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)信息，进一步地，UE在确定Sidelink HARQ信息后可以通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)或者物理上行共享信道(Physical Uplink Shared Channel，PUSCH)将Sidelink HARQ信息发送给网络侧设备(比 如基站)。
因此在Sidelink通信中，无法兼容多种不同的PSFCH反馈时序，使得各UE对PSFCH资源配置的理解出现不一致的情况，从而导致PSFCH资源冲突，接收端无法判断当前Sidelink HARQ信息来自哪个发送端UE。
发明内容

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的副链路反馈资源配置方法进行详细地说明。
参见图2所示，本申请实施例提供一种副链路反馈资源配置方法，由终端设备执行，方法包括以下流程步骤。
步骤201：获取资源配置信息。
可选的，在该步骤201中，可以通过以下方式之一实现对资源配置信息的获取：协议约定，可以理解为通过通信协议预定义所述资源配置信息；网络侧设备配置；预配置；其他终端设备指示。
步骤203：根据所述资源配置信息，确定目标映射方式对应的副链路反馈资源；其中，所述目标映射方式为对应于同一资源池的多个映射方式中的一个，所述目标映射方式对应的副链路反馈资源与所述多个映射方式中的第一映射方式对应的副链路反馈资源之间码域复用。
可选的，上述对应于同一资源池的多个映射方式对应的各副链路反馈资源之间码域复用。
在本申请实施例中，通过副链路进行通信的终端设备，可以根据获取到的资源配置信息，确定进行副链路反馈所需的目标映射方式对应的副链路反馈资源，该目标映射方式为对应于同一资源池的多个映射方式中的一个，且该目标映射方式对应的副链路反馈资源可以与该多个映射方式中的另一个不同的映射方式即第一映射方式对应的副链路反馈资源码域复用。如此，采用 码分复用等方式，能够使各终端设备对副链路反馈资源配置的理解保持一致，实现具有不同的反馈周期的映射方式(mapping)共存，从而避免副链路反馈资源冲突。进一步地，可以使得终端设备支持同一资源池内配置多个映射方式，并使得配置不同映射方式的终端设备之间能够相互通信。同时，还可以支持终端设备在不同的通信需求下，可以采用最合适的反馈周期进行副链路反馈，达到调整通信可靠度、反馈时延以及实现节能省电的目的，从而使得终端设备能够灵活适应多种通信需求。
可选的，上述各映射方式可以指终端设备接收到的数据和反馈资源间的对应关系。
可选的，上述副链路反馈资源可以包括PSFCH资源和/或其他类型的反馈资源。可选的，上述多个映射方式中不同映射方式分别对应的反馈资源可以满足以下之一。
(1)不同映射方式分别对应的反馈资源均是副链路反馈信道PSFCH资源，且副链路反馈信道PSFCH资源对应的格式(format)或序列类型或基序列(例如伪随机序列Pseudo-random sequence，低PAPR序列Low-PAPR sequence)一样，但是不同映射方式分别对应的PSFCH反馈资源之间是复用的，例如可以是码分复用(Code Division Multiplexing，CDM)、频分复用(Frequency Division Multiplexing，FDM)或时分复用(Time Division Multiplexing，TDM)等。
(2)不同映射方式分别对应的反馈资源均是副链路反馈信道PSFCH反馈资源，但是不同的副链路反馈信道反馈PSFCH资源对应的format或序列类型或基序列(例如Pseudo-random sequence，Low-PAPR sequence)不一样。
(3)不同映射方式分别对应的反馈资源不一样，包括副链路反馈信道PSFCH反馈资源和其他信道类型的反馈资源(例如PSXCH反馈资源)。
可选的，上述多个映射方式中任意两个映射方式之间的区别可以为：两个映射方式分别对应的资源周期N、反馈时延k、占用的资源、format和反馈信道中的至少一项不同。其中，映射方式占用的资源可以包括占用的时域 资源、频域资源和码域资源中的至少一种。
在一个示例中，上述多个映射方式中的一个mapping(可以理解为终端设备使用的源mapping或base mapping)的资源周期(或反馈周期)为N1、另一个mapping(可以理解为目标mapping)的资源周期(或反馈周期)为N2；通过本申请实施例的方案，可以在源mapping的基础上生成与该源mapping共存的新的mapping，还可以包括其他共存的mapping，包括但不限于目标mapping，此处以两个mapping为例进行说明。其中：
(1)当N1<N2时，即增大了反馈周期时，可以达到降低反馈功率，实现省电(powersaving)。
(2)当N1>N2时，即减小了反馈周期时，可以降低反馈时延，提升通信可靠度。
(3)当N1＝N2时，k值越大，则反馈时延越大，反馈功率水平越低；其中，更大的时延意味着更低的UE实现成本与处理功耗，即UE可以使用更低端更节能的芯片。
可选的，在本申请实施例的副链路反馈资源配置方法中，上述资源配置信息包括以下至少之一：循环移位配置；循环移位偏移值；基序列配置；信道或信号格式；开销指示值；映射方式的类型；映射方式的索引；反馈资源周期；反馈时延。也就是说，可以通过前述资源配置信息中的一个或多个，准确地确定终端设备所需的目标映射方式对应的副链路反馈资源。
可选的，在本申请实施例的副链路反馈资源配置方法中，上述资源配置信息可以基于以下至少一项指示。
(1)副链路控制信息(Sidelink Control Information，SCI)；可以理解为，上述资源配置信息可以携带在SCI中。
(2)SCIformat；可以理解为，上述资源配置信息由SCIformat隐式的指示给终端设备。例如，第一mapping对应的UE将反馈资源周期N的值通过SCI format隐式指示给目标mapping对应的UE。一种可能的实现方式为：假设第一mapping对应的N值为2，约定SCI format 1-A隐式指示N值为2， 则当目标mapping对应的UE收到SCI format 1-A时，即可获得对端UE的mapping中N值为2。
(3)副链路系统信息块(System Information Block，SIB)；可以理解为，上述配置信息可以携带在副链路SIB中。
(4)媒体接入控制(Medium Access Control，MAC)控制单元(Control Element，CE)；可以理解为，上述配置信息可以携带在MAC CE中。
(5)MAC协议数据单元(Protocol Data Unit，PDU)；可以理解为，上述配置信息可以携带在MACPDU中。
(6)PC5无线资源控制(Radio Resource Control，RRC)请求；可以理解为，上述配置信息可以携带在通过PC5接口发送的RRC请求中。
(7)连接建立消息；可以理解为，上述配置信息可以携带在连接建立消息中，其中，该连接建立消息至少可以包括sl-ConfigDedicatedNR、SIB12或SidelinkPreconfigNR等。
可选的，在本申请实施例的副链路反馈资源配置方法中，上述步骤203，在资源配置信息为不同对象时，可以至少执行为以下具体实施例，但不限于此。
具体实施例一
在该具体实施例一中，上述资源配置信息可选的包括循环移位配置，上述步骤203，可以具体执行为如下内容。
步骤a：根据所述资源配置信息中的循环移位配置进行循环移位，确定所述目标映射方式对应的副链路反馈资源。可以理解，在该实施例中，基于获取到的与目标映射方式关联的循环移位配置进行相应的循环移位，可以准确地确定终端设备所需的目标映射方式对应的副链路反馈资源，其中，该目标映射方式对应的副链路反馈资源和第一映射方式对应的副链路反馈资源对应部分相同或完全不相同的码域资源。
可选的，针对获取到的资源配置信息中的循环移位配置的不同情形，上述步骤a，可以对应执行为不同的具体内容，可以参见如下示例。
在该具体实施例一的示例一中，在获取到的循环移位配置中，目标映射方式对应的目标循环移位配置与多个映射方式中的某一特定的映射方式即第一映射方式对应的第一循环移位配置是不同的。此时，上述步骤a可以执行为如下内容。
在所述资源配置信息中的所述目标映射方式对应的目标循环移位配置与所述第一映射方式对应的第一循环移位配置不同的情况下，根据所述目标循环移位配置中的循环移位值进行循环移位，确定所述目标映射方式对应的副链路反馈资源。也就是说，当目标映射方式和第一映射方式分别对应不同的循环移位配置时，可以直接根据从获取到的目标映射方式自身对应的目标循环移位配置中选择的循环移位值，确定其对应的副链路反馈资源。
在该具体实施例一的示例二中，在获取到的循环移位配置中，目标映射方式对应的目标循环移位配置与第一映射方式对应的第一循环移位配置是相同的。此时，上述步骤a可以执行为如下内容。
在所述资源配置信息中的所述目标映射方式对应的目标循环移位配置与所述第一映射方式对应的第一循环移位配置相同的情况下，确定与所述目标循环移位配置不同的第二循环移位配置；根据所述第二循环移位配置中的循环移位值进行循环移位，确定所述目标映射方式对应的副链路反馈资源。也就是说，当目标映射方式和第一映射方式对应相同的循环移位配置时，可以先为目标映射方式选择一个与第一循环移位配置不同的循环移位配置即第二循环移位配置，进而根据从该第二循环移位配置中选择的循环移位值，确定目标映射方式对应的副链路反馈资源。
在该具体实施例一的示例三中，在获取到的循环移位配置中，目标映射方式对应的目标循环移位配置与第一映射方式对应的第一循环移位配置是相同的。此时，上述步骤a可以执行为如下内容。
在所述资源配置信息中的所述目标映射方式对应的目标循环移位配置与所述第一映射方式对应的循环移位配置相同的情况下，根据目标循环移位偏移值和所述目标循环移位配置中的循环移位值进行循环移位，确定所述目标 映射方式对应的副链路反馈资源。也就是说，当目标映射方式和第一映射方式对应相同的循环移位配置，且获取到的资源配置信息进一步还包括循环移位偏移值(CSoffset)时，可以根据目标循环移位偏移值和目标循环移位配置中的循环移位值一同进行循环移位，确定目标映射方式对应的副链路反馈资源。
可选的，所述目标循环移位偏移值由协议约定、预配置、网络侧设备配置或其他终端设备指示。
可选的，对于上述示例二和示例三中，目标映射方式对应的目标循环移位配置与第一映射方式对应的第一循环移位配置是相同的情况，此时，多个映射方式分别对应的循环移位配置均可以相同。
在该具体实施例一的示例四中，上述步骤a还可以具体执行为如下内容。
根据所述资源配置信息中的循环移位配置，对所述目标映射方式对应的第一副链路反馈资源的序列进行循环移位，确定所述目标映射方式对应的副链路反馈资源，其中所述第一副链路反馈资源为所述目标映射方式对应的副链路反馈资源中与所述第一映射方式对应的副链路反馈资源发生冲突的资源。也就是说，通过获取到的循环移位配置，可以对目标映射方式与第一映射方式间发生冲突的部分资源的序列进行循环移位，以确定目标映射方式对应的副链路反馈资源。例如，UE在可选的循环移位值范围中选择循环移位值，对冲突的频域反馈资源的基序列进行循环移位，此时，不同mapping间不冲突的频域资源的循环移位值可能相同或也可能不同。进一步地，UE可以在该可选的循环移位值范围中随机选择循环移位值。
可选的，上述冲突的资源具体为所述目标映射方式对应的副链路反馈资源中与所述第一映射方式对应的副链路反馈资源中对应不同反馈信息的频域资源。在一个示例中，第一mapping和第二mapping分别如图3和图4所示，此时，两个mapping对应的PSFCH资源在频域相互重叠且均占用的RB数相同，均为16RB。PSSCH1和PSSCH3对应的反馈资源冲突，冲突部分占用2RB。
在该具体实施例一的示例五中，上述步骤a还可以具体执行为如下内容。
根据所述资源配置信息中的循环移位配置，对所述目标映射方式对应的所有副链路反馈资源的序列进行循环移位，确定所述目标映射方式对应的副链路反馈资源。也就是说，通过获取到的循环移位配置，可以对目标映射方式对应的所有副链路反馈资源的序列进行循环移位，以确定目标映射方式对应的副链路反馈资源。例如，UE在可选的循环移位值范围中选择循环移位值，对全部的频域反馈资源的基序列进行循环移位。进一步地，UE可以在该可选的循环移位值范围中随机选择循环移位值。
可选的，在该具体实施例一中，在上述终端设备采用第一反馈机制进行HARQ反馈、且所述资源配置信息中的循环移位配置为循环移位对的情况下，所述循环移位对中的一个循环移位值用于反馈否定确认(NACK)对应的序列、另一个循环移位值用于反馈肯定确认(ACK)对应的序列。可以理解为，若获取到的循环移位配置为循环移位对，则每组循环移位对中的一个循环移位值用于反馈NACK的序列，另一个循环移位值用于反馈ACK的序列；例如，UE获取到的循环移位对配置为{1,3,5}，则循环移位值{1,3,5}用于反馈NACK的序列，循环移位值{1+6,3+6,5+6}＝{7,9,11}用于反馈ACK的序列。
可选的，在该具体实施例一中，在上述终端设备采用第二反馈机制进行HARQ反馈、且所述资源配置信息中的循环移位配置为循环移位对的情况下，所述循环移位对中的循环移位值用于反馈NACK对应的序列。也就是说，所述循环移位对中的任一循环移位值均可以用于反馈NACK对应的序列。可以理解为，若获取到的循环移位配置为循环移位对，则每组循环移位对中的任何一个循环移位值均可以用于反馈NACK的序列，那么，进一步地，可以选用循环移位对中的循环移位值的中一个反馈NACK的序列；例如，UE获取到的循环移位对配置为{1,3,5}，则循环移位值{1,3,5,7,9,11}用于反馈NACK的序列。
例如，当不同mapping获取不同的循环移位配置时，UE获取的循环移位配置为循环移位对，第一mapping对应的UE根据网络配置获取的循环移位 对为{0,2,4}，目标mapping对应的UE根据网络配置获取的循环移位对为{1,3,5}。可选的，当UE对全部的反馈资源的序列进行循环移位，且反馈NACK或ACK时，目标mapping对应的UE在{1,3,5}中随机选择一个循环移位值，例如为3，则UE对全部的16RB反馈资源的序列进行循环移位，且发送NACK的序列对应的循环移位值为3，发送ACK的序列对应的循环移位值为9。可选的，当UE对全部的反馈资源的序列进行循环移位，且仅反馈NACK时，目标mapping对应的UE在{1,3,5,7,9,11}中随机选择一个循环移位值，例如为7，则UE对全部的16RB反馈资源的序列进行循环移位，且发送NACK的序列对应的循环移位值为7。
再例如，当不同mapping获取相同的资源池循环移位配置时，UE获取的循环移位配置为循环移位对，第一mapping和目标mapping对应的UE根据网络配置获取当前资源池的循环移位对配置为{0,2,4}。进一步地，由于循环移位对的全集为{0,1,2,3,4,5}，则不属于当前资源池配置的循环移位对为{1,3,5}。可选的，当UE对冲突的反馈资源的序列进行循环移位，且反馈NACK或ACK时，目标mapping对应的UE在{1,3,5}中随机选择一个循环移位值，例如为3，则UE对冲突的2RB反馈资源的序列进行循环移位，且发送NACK的序列对应的循环移位值为3，发送ACK的序列对应的循环移位值为9。此时不冲突的14RB反馈资源的循环移位值与第一mapping的循环移位值可能相同或不同。可选的，当UE对全部的反馈资源的序列进行循环移位，且反馈NACK或ACK时，目标mapping对应的UE在{1,3,5}中随机选择一个循环移位值，例如为3，则UE对全部的16RB反馈资源的序列进行循环移位，且发送NACK的序列对应的循环移位值为3，发送ACK的序列对应的循环移位值为9。可选的，当UE对冲突的反馈资源的序列进行循环移位，且仅反馈NACK时，目标mapping对应的UE在{1,3,5,7,9,11}中随机选择一个循环移位值，例如为7，则UE对冲突的2RB反馈资源的序列进行循环移位，且发送NACK的序列对应的循环移位值7。此时不冲突的14RB反馈资源的循环移位值与第一mapping的循环移位值可能相同或不同。可选的，当UE对 全部的反馈资源的序列进行循环移位，且仅反馈NACK时，目标mapping对应的UE在{1,3,5,7,9,11}中随机选择一个循环移位值，例如为7，则UE对全部的16RB反馈资源的序列进行循环移位，且发送NACK的序列对应的循环移位值为7。
又例如，当UE获取的循环移位配置为循环移位对，第一mapping和目标mapping对应的UE根据网络配置获取的循环移位对配置均为{0,2,4}，且目标mapping对应的UE预配置了循环移位偏移值＝1。此时目标mapping实际可选的循环移位对为{0+1,2+1,4+1}＝{1,3,5}。可选的，当UE对全部的反馈资源的序列进行循环移位，且反馈NACK或ACK时，目标mapping对应的UE在{1,3,5}中随机选择一个循环移位值，例如为3，则UE对全部的16RB反馈资源的序列进行循环移位，且发送NACK的序列对应的循环移位值为3，发送ACK的序列对应的循环移位值为9。可选的，当UE对全部的反馈资源的序列进行循环移位，且仅反馈NACK时，目标mapping对应的UE在{1,3,5,7,9,11}中随机选择一个循环移位值，例如为7，则UE对全部的16RB反馈资源的序列进行循环移位，且发送NACK的序列对应的循环移位值为7。
具体实施例二
在该具体实施例二中，上述资源配置信息可选的包括基序列配置，上述步骤203，可以具体执行为如下具体内容。
步骤b：根据所述资源配置信息中的基序列配置，确定所述目标映射方式对应的副链路反馈资源。可以理解，在该实施例中，基于获取到的与目标映射方式关联的基序列配置中的基序列，可以准确地确定终端设备所需的目标映射方式对应的副链路反馈资源。其中，该目标映射方式对应的副链路反馈资源和第一映射方式对应的副链路反馈资源对应部分相同或完全不同的码域资源。
可选的，针对获取到的基序列配置的不同情形，上述步骤b，可以对应执行为不同的具体内容，可以参见如下示例。
在该具体实施例二的示例一中，在获取到的循环移位配置中，目标映射 方式对应的目标基序列配置与第一映射方式对应的第一基序列配置是不同的，此时，上述步骤b可以执行为如下内容。
在所述资源配置信息中的所述目标映射方式对应的目标基序列配置与所述第一映射方式对应的第一基序列配置不同的情况下，根据在所述目标基序列配置中选择的基序列，确定所述目标映射方式对应的副链路反馈资源。也就是说，当目标映射方式和第一映射方式分别对应不同的基序列配置时，可以直接根据获取到的目标映射方式自身对应的目标基序列配置确定其对应的副链路反馈资源。
在该具体实施例二的示例二中，在获取到的循环移位配置中，目标映射方式对应的目标基序列配置与第一映射方式对应的第一基序列配置是相同的，此时，上述步骤b可以执行为如下内容。

在该具体实施例二的示例三中，上述步骤b还可以具体执行为如下内容。
根据所述资源配置信息中的基序列配置，对所述目标映射方式对应的第二副链路反馈资源应用目标类型的基序列，确定所述目标映射方式对应的副链路反馈资源，所述第二副链路反馈资源为所述目标映射方式对应的副链路反馈资源中与所述第一映射方式对应的副链路反馈资源发生冲突的资源；其中，所述目标类型的基序列与所述第一映射方式对应的第一类型的基序列不同。也就是说，通过获取到的基序列配置，可以对目标映射方式与终端设备当前的源映射方式间发生冲突的部分资源应用不同类型的基序列，以确定目标映射方式对应的副链路反馈资源。例如，UE在可选的基序列范围中选择基 序列，应用于上述冲突的资源，此时，不同mapping间不冲突的频域资源的循环移位值可能相同或也可能不同。进一步地，UE可以在该可选的基序列范围中随机选择基序列。
可选的，上述第一副链路反馈资源具体为所述目标映射方式对应的副链路反馈资源中与所述第一映射方式对应的副链路反馈资源在频域发生冲突的资源。
在该具体实施例一的示例四中，上述步骤b还可以具体执行为如下内容。
根据所述资源配置信息中的基序列配置，对所述目标映射方式对应的所有副链路反馈资源应用所述目标类型的基序列，确定所述目标映射方式对应的副链路反馈资源；其中，所述目标类型的基序列与所述第一映射方式对应的第一类型的基序列不同。也就是说，通过获取到的基序列配置，可以对目标映射方式对应的所有副链路反馈资源应用不同类型的基序列，以确定目标映射方式对应的副链路反馈资源。例如，UE在可选的基序列范围中选择基序列，应用于全部的频域反馈资源。进一步地，UE可以在该可选的基序列范围中随机选择基序列。
例如，当不同mapping获取不同的基序列配置时，第一mapping对应的UE根据网络配置获取的基序列为ZC序列，目标mapping对应的UE根据网络配置获取的基序列为m序列，则目标mapping对应的UE选择m序列发送HARQ-ACK信息。可选的，UE对全部的16RB反馈资源使用m序列。
再例如，当不同mapping获取相同的资源池基序列配置时，第一mapping和目标mapping对应的UE根据网络配置获取当前资源池的基序列配置为ZC序列，UE预配置的可选基序列包括ZC序列和m序列，则目标mapping对应的UE选择m序列发送HARQ-ACK信息。可选的，UE对冲突的2RB反馈资源使用m序列，其余未冲突的14RB反馈资源使用ZC序列。可选的，UE对全部的16RB反馈资源使用m序列。
具体实施例三
在该具体实施例三中，上述资源配置信息可选的包括信道或信号格式， 上述步骤203，可以具体执行为如下具体内容。
步骤c：根据所述资源配置信息中的信道或信号格式，确定所述目标映射方式对应的副链路反馈资源。可以理解，在该实施例中，基于获取到的与目标映射方式关联的信道或信号格式，可以准确地确定终端设备所需的目标映射方式对应的副链路反馈资源。其中，该目标映射方式对应的副链路反馈资源和第一映射方式对应的副链路反馈资源对应部分相同或完全不同的码域资源。
可选的，上述获取到的信道或信号格式为所述目标映射方式对应的副链路反馈资源的目标信道或信号格式，此时，上述步骤c，可以具体执行为如下内容。
根据目标信道或信号格式，确定所述目标映射方式对应的副链路反馈资源；其中，所述目标信道或信号格式为所述目标映射方式对应的副链路反馈资源所在的信道或信号格式。
可选的，上述根据目标信道或信号格式，确定所述目标映射方式对应的副链路反馈资源的步骤，可以执行为以下示例之一。
在该具体实施例三的示例一中，根据所述目标信道或信号格式的序列长度，确定所述目标映射方式对应的副链路反馈资源，所述目标信道或信号格式的序列长度与所述第一映射方式对应的信道或信号格式的序列长度不同。例如，UE设置PSFCHformat 0的序列长度为
Figure PCTCN2021109027-appb-000001
即目标信道或信号格式的序列长度，该长度与第一mapping对应的序列长度不同。其中，m为大于0的整数，
Figure PCTCN2021109027-appb-000002
为每个RB中的子载波数。
又例如，目标mapping对应的UE使用PSFCHformat 0发送HARQ-ACK信息，且设置format 0的序列长度为
Figure PCTCN2021109027-appb-000003
此时，第一mapping使用的序列长度为默认值，即
Figure PCTCN2021109027-appb-000004
在该具体实施例三的示例二中，根据所述目标信道或信号格式的类型，确定所述目标映射方式对应的副链路反馈资源，所述目标映射方式对应的副链路反馈资源的一个资源集用于携带多个HARQ反馈信息，或者所述目标映 射方式对应的副链路反馈资源的多个资源集共同用于携带多个HARQ反馈信息；其中，所述多个HARQ反馈信息与多个对端终端设备一一对应，所述资源集与预设时隙和预设子信道对应的时频域资源关联。例如，在PSFCHformat X中，UE将对所有TX UE的数据的接收反馈映射至同一个PSFCH资源集，即一个PSFCH资源集携带多个TXUE的HAQR-ACK反馈信息。
又例如，目标mapping对应的UE使用PSFCHformat 1发送HARQ-ACK信息，其中format 1同时承载对PSSCH1、PSSCH2、PSSCH3和PSSCH4的接收反馈，假设目标mapping对应的UE成功收到了来自所有TXUE的数据，则反馈长度为4bits的HAQR-ACK信息a 0,a 1,a 2,a 3，其值分别为1,1,1,1。
也就是说，可以通过该目标映射方式对应的副链路反馈资源的一个资源集携带多个HARQ反馈信息，比如，1个资源集用于携带4个用户的HARQ反馈信息。或者，还可以通过该目标映射方式对应的副链路反馈资源的多个资源集作为一个整体来携带多个HARQ反馈信息，比如，将2个资源集作为一个整体携带4个用户的HARQ反馈信息。
需要说明的是，在本申请实施例的副链路反馈资源配置方法中，根据资源配置信息确定目标映射方式对应的副链路反馈资源时，除了上述具体实施例中记载的方案外，资源配置信息还可以是上述不同类型的信息间的组合等等。其中，上述开销指示值用于指示所述目标映射方式的副链路反馈资源开销，比如，可以具体指示PSFCH资源的开销和/或资源集的开销。
在一个示例中，当资源配置信息指示开销指示值时，第一mapping对应的UE将开销指示值通过SCI指示给第二mapping对应的UE，用于指示第二mapping的频域资源开销，一种可能的实现方式为：通过SCI format 1-A指示，即在SCI format 1-A中新增一个指示域PSFCHoverhead，占用a 0,a 1共2bits，用于指示一个百分比值，第二mapping的UE根据获取到的百分比值，即可推算出第二mapping的PSFCH资源数，如下表1所示。
表1
a 0,a 1 开销值Overhead
0,0 25％
0,1 50％
1,0 75％
1,1 100％
在另一个示例中，当资源配置信息指示反馈时延k的值时，第一mapping对应的UE将k的值通过SCI指示给第二mapping对应的UE，一种可能的实现方式为：通过SCI format 1-A的指示域2nd-stage SCI format，实现对k值对应的索引的指示，占用a 0,a 1共2bits，如下表2所示。
表2
2nd-stage SCI format阈值 2nd-stage SCI format
00 SCI format 2-A
01 SCI format 2-B
10 k＝2
11 k＝3
例如，第一mapping对应的k值为2，则2 nd-stage SCI format指示的索引为2，设置a 0,a 1对应的值分别为1,0。
在又一个示例中，当资源配置信息指示反馈资源周期N和反馈时延k的值时，第一mapping对应的UE将N和k的值同时通过SCI指示给第二mapping对应的UE，一种可能的实现方式为：使用预留(Reserved)比特指示，占用a 0,a 1,a 2,a 3共4bits，用于指示N值和k值的组合对应的索引，如下表3所示。
例如，第一mapping对应的N值为2，k值为2，即需要指示的索引为3，则设置a 0,a 1,a 2,a 3对应的值分别为0,0,1,1。
可选的，在本申请实施例的副链路反馈资源配置方法中，上述资源配置信息除了可以用于确定目标映射方式外，还可以用于确定其他终端设备对应的映射方式。

可选的，在本申请实施例的副链路反馈资源配置方法中，在上述多个映射方式中的第二映射方式对应的副链路反馈资源的资源块(Resource Block，RB)数与所述多个映射方式中的第三映射方式对应的副链路反馈资源的资源块数相同的情况下，所述第二映射方式对应的资源集中的资源块数和所述第三映射方式对应的资源集中的资源块数满足以下之一。
(1)若所述第二映射方式对应的第一反馈周期小于所述第三映射方式对应的第二反馈周期，则所述第三映射方式对应的资源集中的资源块数小于所述第二映射方式对应的资源集中的资源块数。
(2)若所述第一反馈周期大于所述第二反馈周期，则所述第三映射方式对应的资源集中的资源块数大于所述第二映射方式对应的资源集中的资源块数。
(3)若所述第一反馈周期等于所述第二反馈周期，则所述第三映射方式对应的资源集中的资源块数等于所述第二映射方式对应的资源集中的资源块数。
其中，所述第二映射方式和所述第三映射方式为所述多个映射方式中不同的任意两个映射方式，所述资源集与预设时隙和预设子信道对应的时频域资源关联。
在一个示例中，第二mapping和第三mapping的PSFCH资源的RB数相同，均为16RB，则图5中资源集的RB数为16/4＝4，图6中资源集的RB数 为16/8＝2，即第三mapping的资源集RB数小于第二mapping的资源集RB数。
可选的，在本申请实施例的副链路反馈资源配置方法中，在上述多个映射方式中的第四映射方式对应的资源集中的资源块数与所述多个映射方式中的第五映射方式对应的资源集中的资源块数相同的情况下，所述第四映射方式对应的副链路反馈资源的资源块数和所述第五映射方式对应的副链路反馈资源的资源块数满足以下之一。
(1)若所述第四映射方式对应的第三反馈周期小于所述第五映射方式对应的第四反馈周期，则所述第五映射方式对应的副链路反馈资源的资源块数大于所述第四映射方式对应的资源集中的资源块数。
(2)若所述第三反馈周期大于所述第四反馈周期，则所述第五映射方式对应的副链路反馈资源的资源块数小于所述第四映射方式对应的资源集中的资源块数。
(3)若所述第三反馈周期等于所述第四反馈周期，则所述第五映射方式对应的副链路反馈资源的资源块数等于所述第四映射方式对应的资源集中的资源块数。
其中，所述第四映射方式和所述第五映射方式为所述多个映射方式中不同的任意两个映射方式，所述资源集与预设时隙和预设子信道对应的时频域资源关联。
在一个示例中，第四mapping和第五mapping的资源集的RB数相同，均为1RB，则图7中PSFCH资源的RB数为4*1＝4，图8中PSFCH资源的RB数为8*1＝8，即第五mapping的PSFCH资源RB数大于第四mapping的PSFCH资源RB数。
可选的，在本申请实施例的副链路反馈资源配置方法中，还可以包括以下内容：获取时域偏移值；根据所述时域偏移值，对所述多个映射方式中的第六映射方式对应的时域资源进行时域偏移；其中，所述多个映射方式中的第七映射方式对应的时域资源和时域偏移后的所述第六映射方式对应的时域 资源满足目标位置关系，所述第七映射方式对应的时域资源未进行时域偏移。
可以理解为，可以根据接收到的时域偏移值对多个映射方式中的任一映射方式对应的时域资源进行时域偏移，并可以使得多个映射方式中与进行了时域偏移的映射方式不同的另一个映射方式对应的时域资源和该进行了时域偏移的映射方式对应的时域资源满足一定的时域位置关系。
可选的，上述目标位置关系包括以下之一。
(1)时域偏移后的所述第六映射方式对应的偶数时隙和所述第七映射方式对应的偶数时隙对齐。
(2)时域偏移后的所述第六映射方式对应的偶数时隙和所述第七映射方式对应的奇数时隙对齐。
(3)时域偏移后的所述第六映射方式对应的时隙起点(比如时隙0)和所述第七映射方式对应的时隙起点对齐。
在一个示例中，第六mapping和第七mapping间的时域关系如图9所示，图中上半部分为第六mapping，下半部分为第七mapping，第六mapping对应的UE根据网络配置获取时域偏移值t_offset＝2slots，若采用slot index＝slot index-t_offset的方式对第六mapping进行时域偏移，则偏移后的时域关系如图10所示，此时第六mapping的时隙0和第七mapping的时隙0对齐。
需要说明的是，本申请实施例的副链路反馈资源配置方法，以副链路反馈资源为PSFCH资源为例，PSSCH与对应的PSFCH反馈资源间存在两种映射规则：
Option 1：HARQ-ACK信息仅在PSSCH数据占用的子信道中起始子信道对应的PSFCH反馈资源上传输。
Option 2：HARQ-ACK信息在PSSCH数据占用的全部子信道对应的PSFCH反馈资源上传输。
