图1为本申请实施例提供的一种信号传输方法的流程示意图，由基站(Base Station，BS)执行，如图1所示，该信号传输方法包括以下步骤：
S101，发送配置信息，配置信息包括候选资源。
在本申请的一些实施例中，基站可向用户终端发送配置信息，配置信息包括候选资源。应说明的是，候选资源为用户终端向基站发送信令和/或信息时所使用的上行资源。可以理解的是，候选资源可为一个或多个。
可选的，配置信息还包括以下至少一种：候选波束、候选资源和候选波束之间的对应关系表、候选资源和候选波束之间的对应方法的标识。
本实施例中，基站可预先配置候选波束、候选资源和候选波束之间的对应关系表、候选资源和候选波束之间的对应方法的标识，并将上述配置的三种信息的至少一种，以及候选资源，作为配置信息，发送至用户终端。作为另一种可能的实施方式，用户终端可预先配置候选波束、对应方法、用于配置对应关系的计算公式中的至少一种。
可以理解的是，候选资源和候选波束均为一个或多个，且候选资源和候选波束之间具有对应关系，每个候选资源对应一个候选波束。对于每个资源分配周期中的多个候选资源，一个候选波束可以对应一个或多个候选资源。例如，在10ms资源分配周期中有4个候选资源，若有4个候选波束，则每个候选波束可对应1个候选资源，若有2个候选波束，则每个候选波束可对应2个候选资源。
可选的，配置候选资源和候选波束之间的对应关系表，可包括以下至少一种：
方式1、根据候选资源、候选波束和对应方法，采用预设的对应方法配置候选资源和候选波束之间的对应关系表。
本实施例中，用户终端中预先设置了一种对应方法，则可采用预设的对应方法配置候选资源和候选波束之间的对应关系表。
或者，用户终端中预先设置了多种对应方法，则可根据基站发送的对应方法的标识，从预设的多种计算公式中获取标识对应的对应方法，并采用标识对应的对应方法，配置候选资源和候选波束之间的对应关系表。
方式2、根据候选资源、候选波束和对应方法，采用预设的对应方法对应的计算公式，配置候选资源和候选波束之间的对应关系表。
本实施例中，用户终端中预先设置了一种对应方法对应的计算公式，则可采用预设的对应方法对应的计算和公式配置候选资源和候选波束之间的对应关系表。
或者，用户终端中预先设置了多种对应方法对应的计算公式，则可根据基站发送的对应方法的标识，从预设的多种计算公式中获取标识对应的对应方法对应的计算公式，并采用标识对应的对应方法对应的计算公式，配置候选资源和候选波束之间的对应关系表。
上述预设对应方法及其对应的计算公式包括但不限于下述三两种形式：
如，对应方法为将候选资源在候选波束中交错分配。对应的计算公式推导过程如下：假设1个资源分配周期中的候选资源的总数量为N，候选资源的编号为从0到N-1。波束的总数量为M，波束的编号 为0到M-1。则每个波束分配到的资源数量为N/M。则为第i个波束分配的资源编号为i+M*j,j的取值范围为[0,(N/M)-1]。
如，对应方法为将候选资源在候选波束中平均分配。对应的计算公式推导过程如下：假设1个资源分配周期中的候选资源的总数量为N，候选资源的编号为从1到N。波束的总数量为M，波束的编号为1到M。则每个波束分配到的资源数量为N/M。则为第i个波束分配的资源编号为[1+(i-1)*(N/M),1+(i-1)*(N/M)+((N/M)-1)]。
如，对应方法为将候选资源在候选波束中平均分配。对应的另一种计算公式推导过程如下：假设1个资源分配周期中的候选资源的总数量为N，候选资源的编号为从0到N-1。波束的总数量为M，波束的编号为0到M-1。则每个波束分配到的资源数量为N/M。则为第i个波束分配的资源编号为[i*(N/M),i*(N/M)+((N/M)-1)]。
可选的，候选波束可通过广播消息进行配置，候选资源和上述对应关系可通过用户终端的专属信令进行配置，其中，专属信令可为无线资源控制(Radio Resource Control，RRC)信令。
可选的，配置信息还包括以下至少一种：候选资源的类型、候选资源对应的用户终端的状态、候选资源的资源配置信息。
其中，候选资源的类型包括以下类型中的至少一种：数据信道、控制信道和探测信号。例如，数据信道可包括物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，控制信道可包括物理上行控制信道(Physical Uplink Control Channel，PUCCH)，探测信号可包括探测参考信号(Sounding Reference Signal，SRS)。应说明的是，候选资源为上行控制信道时，此时用户终端的上行发送资源为网络配置的上行授权(Configured Grant，CG)。
其中，候选资源对应的用户终端的状态可包括空闲(IDLE)状态、不活跃状态(INACTIVE)。
其中，资源配置信息包括以下信息中的至少一种：资源分配周期、频域资源位置、时域起始资源位置、资源分配周期中的资源数量、相邻资源的时域间隔和相邻资源的频率间隔。应说明的是，频域资源位置包括但不限于小区(Cell)标识、带宽(Bandwidth Part，BWP)标识等。
可选的，配置信息还可包括候选波束的标识。其中，候选波束的标识包括同步信号块(Synchronous Signal Block，SSB)标识和信道状态信息参考信号(Channel State Information–Reference Signaling，CSI-RS)标识中的至少一个。
S102，接收候选资源中的目标资源上的信号。
在本申请的一些实施例中，用户终端可从配置信息中的候选资源中确定目标资源，然后在目标资源上发送信号，进一步地，基站可接收用户终端在目标资源上发送的信号。
可选的，当配置信息还包括候选资源和候选波束之间的对应关系表时，目标资源为候选波束中的目标波束对应的候选资源。关于用户终端如何从配置信息中的候选资源中确定目标资源的相关内容，可参见用户终端侧实施例的相关内容，这里不做限定。
S103，在目标资源对应的目标波束上发送反馈信号。
本申请实施例中，目标资源为候选资源中的一个，目标波束为候选波束中的一个。
在本申请的实施例中，基站可预先配置候选资源和候选波束之间的对应方法，该对应方法可以为候选资源和候选波束的对应关系表，也可以为预设的计算公式，通过该计算公式能够得到候选资源和候选波束的对应关系。例如：基站侧内置有候选资源和候选波束的对应关系表，通过将目标资源带入该对应关系表得到目标波束，并在目标波束上发送反馈信号；又例如：基站侧可以内置有候选资源和候选波束的对应方法，该对应方法包括预设的计算公式，通过对应方法或者计算公式能够得到候选资源和候选波束的对应关系表，通过将该目标资源带入该对应关系表得到目标波束。
在本申请的一些实施例中，基站可在目标资源对应的目标波束上向用户终端发送反馈信号。
相关技术中，当基站在给用户终端配置上行资源时，由于基站的下行发送波束会在不同时间对不同空间位置进行扫描发送，则基站在接收用户终端发送的上行资源时，不清楚用户终端会在哪个波束上接收反馈信号，则无法准确的将下行反馈信号发送至用户终端，进而会导致用户终端无法接收到下行反馈信号。
本实施例中，发送配置信息，配置信息包括候选资源，接收候选资源中的目标资源上的信号，在目标资源对应的目标波束上发送反馈信号。由此，基站可发送包括候选资源的配置信息，并接收候选资源中的目标资源上的信号，并在目标资源对应的目标波束上发送反馈信号，提高了基站发送反馈信号的可靠性。
图2为本申请实施例提供的另一种信号传输方法的流程示意图，由基站执行。如图2所示，该信号传输方法包括以下步骤：
S201，发送配置信息，配置信息包括候选资源，还包括候选波束、候选资源的编号和候选波束的编号之间的对应关系表中的至少一项。
在本申请的一些实施例中，候选资源和候选波束之间的对应关系表，包括：候选资源的编号和候选波束的编号之间的对应关系表。
可以理解的是，基站在发送配置信息之前，可配置候选资源的编号和候选波束的编号之间的对应关系表。可包括如下两种可能的实施方式：
方式1、根据候选波束的数量确定分组数量，将连续编号的候选资源划分为同一分组，将同一分组的候选资源的编号与同一个候选波束的编号对应，得到候选资源的编号和候选波束的编号之间的对应关系表。
例如，候选资源的数量为8个，则可确定分组数量为2，将编号为1至4的候选资源划分为分组1，将编号为5至8的候选资源划分为分组2，将分组1内的候选资源的编号1至4与候选波束1对应，将分组2内的候选资源的编号5至8与候选波束2对应。
方式2、根据候选波束的数量确定分组数量，将顺序编号的候选资源按照分组编号依次进行交错分组，将同一分组的候选资源的编号与同一个候选波束的编号对应，得到候选资源的编号和候选波束的编号之间的对应关系表。
例如，候选资源的数量为9个，则可确定分组数量为2，将编号为1、3、5、7、9的候选资源划分为分组1，将编号为2、4、6、8的候选资源划分为分组2，将分组1内的候选资源的编号1、3、5、7、9与候选波束1对应，将分组2内的候选资源的编号2、4、6、8与候选波束2对应。
在本申请的一些实施例中，为了区分同一个资源分配周期内的多个候选资源，资源分配周期中的不同候选资源的时域资源、频域资源和解调信号中的至少一种不同。其中，时域资源可包括时隙(SLOT)，频域资源可包括物理资源块(Physical Resource Block，PRB)，解调信号可包括解调参考信号DMRS。
此时，配置候选资源的编号，可包括对候选资源进行时域编号、频域编号和解调信号编号中的至少一种。
其中，时域编号、频域编号和解调信号编号中的至少一种的编号顺序由网络配置确定，或者由网络配置或协议约定的编号规则确定。
例如，时域编号可按照时间顺序或者时间逆序进行编号。比如，若时域编号按照时间顺序进行编号，则时隙为1的候选资源的编号小于时隙为2的候选资源的编号，反之，时域编号按照时间逆序进行编号，则时隙为1的候选资源的编号大于时隙为2的候选资源的编号。
例如，频域编号可按照频率数值从小到大或者从大到小进行编号。比如，频域编号按照频率数值从小到大进行编号，则物理资源块PRB为1的候选资源的编号小于物理资源块PRB为2的候选资源的编号，反之，频域编号按照频率数值从大到小进行编号，则物理资源块PRB为1的候选资源的编号大于物理资源块PRB为2的候选资源的编号。
配置候选资源的编号，若对候选资源进行时域编号、频域编号的组合编号。可包括如下两种可能的实施方式：
方式1、时域编号位于频域编号之前。
可选的，当前时域的最后一个频域资源的下一个资源为距离最后一个频域资源的时间位置最近且频率最近的还未编号的资源。例如，如图3所示，时隙为1的频域资源为资源1至3，则时隙为1的最后一个频域资源为资源3，下一个资源为距离资源3的时间位置最近且频率最近的还未编号的资源，将其作为资源4，进而时隙2的频域资源为资源4至6。
或者，同一时域内的频域资源的编号按照频率数值从小到大或者从大到小进行编号。例如，如图4所示，时隙为1的频域资源的编号按照频率数值从小到大进行编号，编号依次为1至3，时隙为2的频域资源的编号按照频率数值从小到大进行编号，编号依次为4至6。
方式2、频域编号位于时域编号之前。
可选的，当前频域的最后一个时域资源的下一个资源为距离最后一个时域资源的频率位置最近且时间最近的还未编号的资源。例如，如图5所示，频率为f1的时域资源为1至3，则频率为f1的最后一个时域资源为资源3，下一个资源为距离资源3的频率位置最近且时间最近的还未编号的资源，将其作为资源4，进而频率为f2的时域资源为资源4至6。
或者，同一频域内的时域资源的编号按照时间顺序或者时间逆序进行编号。例如，如图6所示，频率为f1的时域资源的编号按照时间顺序进行编号，编号依次为1至3，频率为f2的时域资源的编号按照时间顺序进行编号，编号依次为4至6。
S202，接收候选资源中的目标资源上的信号。
S203，在目标资源对应的目标波束上发送反馈信号。
在本申请的实施例中，步骤S202、步骤S203可以分别采用本申请的各实施例中的任一种方式实现，本申请实施例并不对此作出限定，也不再赘述。
本实施例中，发送配置信息，配置信息包括候选资源，还包括候选波束、候选资源的编号和候选波束的编号之间的对应关系表中的至少一项，接收目标资源上的信号，在目标资源对应的目标波束上发送反馈信号。由此，基站可根据候选资源的编号和候选波束的编号之间的对应关系表，确定目标资源对应的目标波束，并在目标资源对应的目标波束上发送反馈信号，提高了下行反馈信号发送的可靠性。
可以理解的是，候选资源的类型为数据信道时，资源分配周期中的候选资源的混合自动重传请求(Hybrid Automatic Repeat Request，HABQ)进程编号相同,或者，配置的全部候选资源的混合自动重传请求进程编号相同。
其中，资源分配周期中的候选资源的混合自动重传请求进程编号相同时，资源分配周期中的候选资源的混合自动重传请求进程编号，根据资源分配周期中时域最早、时域最晚、频率最大、频率最小、编号最小和编号最大中的任意一个的候选资源的混合自动重传请求进程编号确定。
图7为本申请实施例提供的另一种信号传输方法的流程示意图，由用户终端执行。如图7所示，该信号传输方法包括以下步骤：
S301，根据候选资源配置、候选波束配置和候选资源和候选波束之间的对应关系配置，在候选波束中选择目标波束。
在本申请的实施例中，用户终端可接收基站发送的配置信息，配置信息包括候选资源，配置信息还可包括候选波束、候选资源和候选波束之间的对应关系表、候选资源和候选波束之间的对应方法的标识中的至少一种。
在本申请的一些实施例中，用户终端可自行配置候选波束、候选资源和候选波束之间的对应方法、用于配置对应关系的计算公式中的至少一种，或者，用户终端可接收基站发送的配置信息，配置信息包括候选波束、候选资源和候选波束之间的对应关系表、候选资源和候选波束之间的对应方法的标识中的至少一种。
可以理解的是，候选资源和候选波束均为一个或多个，且候选资源和候选波束之间具有对应关系，每个候选资源对应一个候选波束。
可选的，配置候选资源和候选波束之间的对应关系，可包括以下至少一种：
方式1、根据候选资源、候选波束和对应方法，采用预设的对应方法配置候选资源和候选波束之间的对应关系。
本实施例中，用户终端中预先设置了一种对应方法，则可采用预设的对应方法配置候选资源和候选波束之间的对应关系表。
或者，用户终端中预先设置了多种对应方法，则可根据基站发送的对应方法的标识，从预设的多种对应方法中获取标识对应的对应方法，并采用标识对应的对应方法配置候选资源和候选波束之间的对应关系。
方式2、根据候选资源、候选波束和对应方法，采用预设的对应方法对应的计算公式，配置候选资源和候选波束之间的对应关系。
本实施例中，用户终端中预先设置了一种对应方法对应的计算公式，则可采用预设的对应方法对应的计算和公式配置候选资源和候选波束之间的对应关系表。
或者，用户终端中预先设置了多种对应方法对应的计算公式，则可根据基站发送的对应方法的标识，从预设的多种计算公式中获取标识对应的对应方法对应的计算公式，并采用标识对应的对应方法对应的计算公式，配置候选资源和候选波束之间的对应关系。
可选的，当网络侧发送的配置信息仅包括候选资源的时候，用户终端检测下行波束对应的参考信号的数量，并根据该参考信号的数量，根据协议约定的规则对下行波束进行编号。如，用户终端检测到1个SSB突发(Burst)中包含了4个SSB信号(如，4个SSB信号根据时间顺序编号为SSB1/2/3/4)，则用户终端确定下行波束的数量为4，该4个SSB信号分别对应4个不同的波束，则波束1对应SSB1,波束2对应SSB2，依次类推。SSB1、SSB2、SSB3和SSB4分别对应的4个波束为候选波束。用户终端根据网络配置的候选资源，其检测到的候选波束，以及预置的候选资源和候选波束的对应方法或者计算公式，获取候选资源和候选波束之间的对应关系表。
上述预设对应方法及其对应的计算公式包括但不限于下述三种形式：
如，对应方法为将候选资源在候选波束中交错分配。对应的计算公式推导过程如下：假设1个资源分配周期中的候选资源的总数量为N，候选资源的编号为从0到N-1。波束的总数量为M，波束的编号 为0到M-1。则每个波束分配到的资源数量为N/M。则为第i个波束分配的资源编号为i+M*j,j的取值范围为[0,(N/M)-1]。
如，对应方法为将候选资源在候选波束中平均分配。对应的计算公式推导过程如下：假设1个资源分配周期中的候选资源的总数量为N，候选资源的编号为从1到N。候选波束的总数量为M，候选波束的编号为1到M。则每个候选波束分配到的候选资源数量为N/M。则为第i个候选波束分配的候选资源编号为[1+(i-1)*(N/M),1+(i-1)*(N/M)+((N/M)-1)]。
如，对应方法为将候选资源在候选波束中平均分配。对应的另一种计算公式推导过程如下：假设1个资源分配周期中的候选资源的总数量为N，候选资源的编号为从0到N-1。候选波束的总数量为M，候选波束的编号为0到M-1。则每个候选波束分配到的候选资源数量为N/M。则为第i个候选波束分配的资源编号为[i*(N/M),i*(N/M)+((N/M)-1)]。
具体地，配置候选资源和候选波束之间的对应关系，可包括如下四种可能的实施方式：
方式1、若用户终端只接收了候选资源配置，则可根据接收的候选资源配置、预设的候选波束配置和预设的对应方法，配置候选资源和所述候选波束之间的对应关系；或者，根据接收的候选资源配置、预设的候选波束配置和预设的计算公式，配置候选资源和候选波束之间的对应关系。

方式3、若用户终端只接收了候选资源配置,以及候选资源和候选波束之间的对应方法的标识，则可根据对应方法的标识获取预设的对应方法或对应方法对应的计算公式，然后根据接收的候选资源配置、预设的候选波束配置和预设的对应方法，配置候选资源和候选波束之间的对应关系；或者，根据接收的候选资源配置、预设的候选波束配置和对应方法对应的计算公式，配置候选资源和候选波束之间的对应关系。
方式4、若用户终端只接收了候选资源配置、候选波束配置、以及候选资源和候选波束之间的对应方法的标识，则可根据对应方法的标识获取预设的所述对应方法或对应方法对应的计算公式，然后根据接收的候选资源配置、接收的候选波束配置和预设的对应方法，配置候选资源和候选波束之间的对应关系；或者，根据接收的候选资源配置、接收的候选波束配置和对应方法对应的计算公式，配置候选资源和候选波束之间的对应关系。

例如，可在接收的候选资源和候选波束之间的对应关系表中，查询到候选资源和候选波束之间的对应关系，并根据查询到的候选资源和候选波束之间的对应关系，配置候选资源和候选波束之间的对应关系。
本申请的实施例中，用户终端可在候选波束中选择一个目标波束。
在本申请的一些实施例中，候选资源和候选波束之间的对应关系配置，包括：候选资源的编号和候选波束的编号之间的对应关系配置。
可以理解的是，配置候选资源的编号和候选波束的编号之间的对应关系，可包括如下两种可能的实施方式：
方式1、根据候选波束的数量确定分组数量，将连续编号的候选资源划分为同一分组，将同一分组的候选资源的编号与同一个候选波束的编号对应。
例如，候选资源的数量为8个，则可确定分组数量为2，将编号为1至4的候选资源划分为分组1，将编号为5至8的候选资源划分为分组2，将分组1内的候选资源的编号1至4与候选波束1对应，将分组2内的候选资源的编号5至8与候选波束2对应。
方式2、根据候选波束的数量确定分组数量，将顺序编号的候选资源按照分组编号依次进行交错分组，将同一分组的候选资源的编号与同一个候选波束的编号对应。
例如，候选资源的数量为9个，则可确定分组数量为2，将编号为1、3、5、7、9的候选资源划分为分组1，将编号为2、4、6、8的候选资源划分为分组2，将分组1内的候选资源的编号1、3、5、7、9与候选波束1对应，将分组2内的候选资源的编号2、4、6、8与候选波束2对应。

此时，配置候选资源的编号，可包括对候选资源进行时域编号、频域编号和解调信号编号中的至少 一种。
其中，时域编号、频域编号和解调信号编号中的至少一种的编号顺序由网络配置确定，或者由网络配置或协议约定的编号规则确定。
例如，时域编号可按照时间顺序或者时间逆序进行编号。比如，若时域编号按照时间顺序进行编号，则时隙为1的候选资源的编号小于时隙为2的候选资源的编号，反之，时域编号按照时间逆序进行编号，则时隙为1的候选资源的编号大于时隙为2的候选资源的编号。
例如，频域编号可按照频率数值从小到大或者从大到小进行编号。比如，频域编号按照频率数值从小到大进行编号，则物理资源块PRB为1的候选资源的编号小于物理资源块PRB为2的候选资源的编号，反之，频域编号按照频率数值从大到小进行编号，则物理资源块PRB为1的候选资源的编号大于物理资源块PRB为2的候选资源的编号。
配置候选资源的编号，若对候选资源进行时域编号、频域编号的组合编号。可包括如下两种可能的实施方式：
方式1、时域编号位于频域编号之前。
可选的，当前时域的最后一个频域资源的下一个资源为距离最后一个频域资源的时间位置最近且频率最近的还未编号的资源。例如，如图3所示，时隙为1的频域资源为资源1至3，则时隙为1的最后一个频域资源为资源3，下一个资源为距离资源3的时间位置最近且频率最近的还未编号的资源，将其作为资源4，进而时隙2的频域资源为资源4至6。
或者，同一时域内的频域资源的编号按照频率数值从小到大或者从大到小进行编号。例如，如图4所示，时隙为1的频域资源的编号按照频率数值从小到大进行编号，编号依次为1至3，时隙为2的频域资源的编号按照频率数值从小到大进行编号，编号依次为4至6。
方式2、频域编号位于时域编号之前。

图8为本申请实施例提供的另一种信号传输方法的流程示意图，由用户终端执行。如图8所示，该信号传输方法包括以下步骤：
S401，根据候选资源配置、候选波束配置和候选资源和候选波束之间的对应关系配置，在候选波束中选择目标波束。
在本申请的一些实施例中，在候选波束中选择目标波束，可包括如下两种可能的实施方式：
方式1、将候选波束中测量值等于或者大于预设的测量阈值的候选波束，确定为目标波束。
其中，预设的测量阈值可由网络配置或协议约定确定。
例如，若同步信号块SSB为1的候选波束中参考信号接收功率(Reference Signal Receiving Power，RSRP)等于或者大于预设的测量阈值，则用户终端可选择同步信号块SSB为1的候选波束作为目标波束。
方式2、将候选资源中对应的用户终端的发送时间最近的候选资源对应的候选波束，确定为目标波束。
例如，若资源1的发送时间最近，则可将资源1对应的候选波束确定为目标波束。
在本申请的一些实施例中，候选资源配置可包括候选资源对应的用户终端的状态，其中，用户终端的状态可包括空闲(IDLE)状态、不活跃状态(INACTIVE)。则在候选波束中选择目标波束，可包括如下两种可能的实施方式：
方式1、将候选波束中测量值等于或者大于预设的测量阈值，且对应的候选资源对应的用户终端的状态与用户终端当前的状态一致的候选波束，确定为目标波束。
例如，若同步信号块SSB为1的候选波束中参考信号接收功率(Reference Signal Receiving Power，RSRP)等于或者大于预设的测量阈值，且同步信号块SSB为1的候选波束对应的用户终端的状态与用户终端当前的状态一致，则用户终端可选择同步信号块SSB为1的候选波束作为目标波束。
方式2、将候选资源中对应的用户终端的发送时间最近，且对应的用户终端的状态与用户终端当前的状态一致的候选资源对应的候选波束，确定为目标波束。
例如，若资源1的发送时间最近，且资源1的候选波束对应的用户终端的状态与用户终端当前的状态一致，则可将资源1对应的候选波束确定为目标波束。
S402，根据对应关系确定目标波束对应的候选资源为目标资源。
在本申请的实施例中，步骤S402可以分别采用本申请的各实施例中的任一种方式实现，本申请实施例并不对此作出限定，也不再赘述。
S403，在目标资源上发送信号。
可以理解的是，候选资源配置还可包括候选资源的混合自动重传请求(Hybrid Automatic Repeat Request，HABQ)进程编号、混合自动重传请求进程数量中的至少一项，候选资源的类型为数据信道时，资源分配周期中的候选资源的混合自动重传请求进程编号相同,或者，配置的全部候选资源的混合自动重传请求进程编号相同。
其中，资源分配周期中的候选资源的混合自动重传请求进程编号相同时，资源分配周期中的候选资源的混合自动重传请求进程编号，根据资源分配周期中时域最早、时域最晚、频率最大、频率最小、编号最小和编号最大中的任意一个的候选资源的混合自动重传请求进程编号确定。
可选的，在目标资源上发送信号，可包括根据目标资源的混合自动重传请求进程编号确定目标混合自动重传请求进程，采用目标混合自动重传请求进程在目标资源上发送信号。例如，若目标资源的混合自动重传请求进程编号为5，则可确定目标混合自动重传请求进程为5，采用目标混合自动重传请求进程在目标资源上发送信号。
可选的，在目标资源上发送信号后，还可通过信道监听反馈信号，信道的空间关系根据目标资源对应的目标波束确定。其中，信道包括但不限于物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。
例如，若目标波束为同步信号块SSB为1的候选波束，则信道空间关系可根据同步信号块SSB为1的候选波束确定。
S404，在目标资源对应的目标波束上接收反馈信号。
在本申请的一些实施例中，用户终端可在目标资源对应的目标波束上接收基站发送的反馈信号。
本实施例中，根据候选资源配置、候选波束配置和候选资源和候选波束之间的对应关系配置，在候选波束中选择目标波束，根据对应关系确定目标波束对应的候选资源为目标资源，在目标资源上发送信号，并在目标资源对应的目标波束上接收反馈信号。由此，用户终端可在候选波束中选择目标波束，然 后根据候选资源和候选波束之间的对应关系确定目标波束对应的候选资源为目标资源，在目标资源上发送信号，还可在目标波束上接收反馈信号，提高了用户终端接收反馈信号的可靠性。
