需要说明的是，具体采用哪个频域单元的跳频配置信息，取决于基站的配置和/或终端的能力。
下面结合具体的实施例对本申请的数据传输方法进行说明。
假设上述频域单元为BWP，终端在接入小区后，基站通过高层信令为终端配置BWP切换的相关参数。
1.配置候选BWP集合，确定跳频范围。
基站为终端配置多个BWP，BWP的数量可以根据小区系统带宽或者协议规定的Red Cap终端需要支持的BWP数量确定；
或者，Red Cap终端主动上报终端的跳频能力，基站按照终端的跳频能力为其配置相应的BWP集合。
候选BWP的配置参数可以复用现有协议的BWP配置参数，使用RRC信令配置给终端。
2.基站为终端配置BWP切换参数，包括BWP间跳频或切换的传输模式(BWP激活的先后顺序，各个BWP在激活时的传输时间长度，BWP切换时间)。
所述BWP间跳频的传输模式可以是周期执行的，或者通过DCI，MAC CE信令动态或者半静态的配置给终端。BWP跳频传输模式的周期大于或者等于所有BWP激活时间的总和，如果出现大于的情况，表示传输空闲的时间。
所述BWP间跳频的传输模式的一个周期或者一次传输会包含一个或者多个候选BWP，根据BWP激活的先后顺序依次在不同的传输时机或时隙进行激活并传输上行或者下行信号。每一个激活BWP的传输时间由激活时的传输时间长度进行指示，通常以符号或者时隙或者子帧为粒度。BWP间的切换时机可以由协议规定或者由终端主动上报切换能力。特殊的，如果BWP间跳频的传输模式只包含一个BWP时，表示不跳频的传输模式。
BWP间跳频的时候，BWP的激活时间内的连续多个时间单元具有相同的传输配置指示(Transmission Configuration Indicator，TCI)配置；跳频传输时不同BWP具有相同的TCI配置，所述BWP跳频传输使用的TCI由基站通过RRC信 令或者DCI进行配置。或者，如果在BWP配置时，终端配置了不同BWP的TCI，BWP切换后终端按照配置的TCI进行通信。所述TCI可以应用于终端的所有物理信道，或者应用于配置信息指示的物理信道。
基站可以通过RRC信令为终端配置多套BWP跳频的传输模式，终端按照其中一套或者几套配置进行通信或者传输相应的物理信道。BWP跳频传输模式可以是通过RRC信令激活的进行周期传输的，也可以是通过MAC CE或者DCI动态或者半静态激活的。
3.基站为终端的各个物理信道配置对应的BWP切换传输模式(即跳频配置信息)。
终端的不同上下行物理信道可以配置不同或者相同的BWP切换传输模式。如果所有上下行物理信道使用相同的BWP切换传输模式，终端按照BWP切换传输模式周期地进行BWP切换。
可选地，基站为终端的不同物理信道配置不同的BWP切换传输模式。BWP切换传输模式可以配置于以下至少一种物理信道：PDCCH CSS Type 0/0A/1/2；PDCCH CSS Type 3；PDCCH USS；PDSCH；Non-CD SSB；CSI-RS；PUSCH；PUCCH；PRACH；SRS。或者，该方案不适用(或只能适用于)以下至少一个信道或信号：PDCCH CSS Type 0/0A/1/2；PDCCH CSS Type 3；PDCCH USS；PDSCH；SSB；CSI-RS，PRACH。
例如，对于频分双工(Frequency Division Duplexing，FDD)终端，上行物理信道按照BWP切换模式1进行传输，下行物理信道按照BWP切换模式2进行传输。又例如，PDCCH USS按照BWP切换模式1进行监听，PDCCH CSS在固定BWP(初始下行BWP)上进行监听，PDSCH按照DCI调度的BWP切换模式或者按照周期的BWP切换模式2进行传输。
4.终端按照BWP切换传输模式接收下行信号和/或发送上行信号。
不同时隙和不同物理信道的BWP跳频或切换行为需要占用Y时间长度(若不同BWP具有不同的子载波SCS带宽，导致不同BWP的符号长度不同，或者导致不同BWP的频率重调时间不同；一次BWP跳频或者切换的两个BWP之间的频率切换距离不同导致频率重调时间不同。频率重调时间Y由上述影响因 素而确定)，BWP跳频或切换行为的开始时刻根据不同物理信道特征分别确定。终端可以根据基站调度预留的时间，或者根据协议定义的规则进行BWP切换。
具体的，对于PDCCH，终端按照基站配置在监听时机周期性地监听PDCCH；如果PDCCH中承载了终端的调度信息，则终端执行PDCCH到PDSCH或者PDCCH到PUSCH的跳频和调度行为，归属于不同物理信道BWP切换；如果PDCCH需要监听多个PDCCH传输时机，并且多个PDCCH传输时机按照BWP跳频传输模式对应于不同的BWP，则终端在监听完当前BWP上的最后一个PDCCH监听时机后，且在新BWP上第一PDCCH监听时机开始之前的任意时刻进行BWP切换，保证在新BWP PDCCH监听时机开始之前完成BWP切换。如果PDCCH不同的搜索空间配置了不同的BWP跳频传输模式，例如PDCCH CSS和PDCCH USS配置了不同的BWP跳频传输模式；如果在某些时间段，终端需要监听PDCCH CSS和PDCCH USS，但是两个PDCCH不在同一BWP内，终端按照协议规定从两个BWP中选择一个进行监听(例如，PDCCH CSS优先级高于PDCCH USS，终端切换到PDCCH CSS所在BWP进行监听)，可选地，终端在上述确定的BWP的搜索空间内监听PDCCH CSS和PDCCH USS。
对于PDSCH，终端按照基站的配置在对应的时隙上接收下行数据。当PDSCH需要进行BWP切换时，如果BWP切换前后的PDSCH时隙不连续，且在BWP切换前和PDSCH传输结束后不需要接收或发送其他信号，并且在BWP切换后和PDSCH传输开始前不需要接收或发送其他信号，终端可以在间隔时间内完成BWP切换。如果BWP切换前后PDSCH时隙连续，终端在BWP切换后第一个时隙的前M个符号内完成BWP切换，在第M+1个符号开始接收PDSCH(M个符号可以包含于PDCCH的符号范围内)；或者，终端在BWP切换前最后一个时隙的最后M个符号进行BWP切换；或者，终端在BWP切换前最后一个时隙的最后M1个符号和BWP切换后第一个时隙的前M2个符号(M＝M1+M2，M2包含于PDCCH的符号范围内)完成BWP切换。其中，M是根据频率重调时间的最大值确定的。
对于PUCCH和PUSCH，如果BWP切换前后的PUCCH/PUSCH时隙不连续并且在BWP切换前和PUCCH/PUSCH传输结束后不需要接收或发送其他信 号，并且在BWP切换后和PUCCH/PUSCH传输开始前不需要接收或发送其他信号，终端可以在间隔时间内完成BWP切换。如果BWP切换前后PUCCH/PUSCH时隙连续，终端在BWP切换后第一个时隙的前M个符号内完成BWP切换，在第M+1个符号开始发送PUCCH/PUSCH；或者，终端在BWP切换前最后一个时隙的最后M个符号进行BWP切换；或者，终端在BWP切换前最后一个时隙的最后M1个符号和BWP切换后第一个时隙前M2个符号(M＝M1+M2)完成BWP切换。
对于PDCCH到PDSCH的BWP切换，如果是时隙内调度或者时隙间调度，且PDCCH和PDSCH在同一BWP，终端不需要进行BWP切换，终端在接收完当前BWP的PDSCH后按照上述PDSCH的BWP切换行为切换到其他BWP上接收后续PDSCH；如果是时隙间调度，并且PDCCH和PDSCH在不同BWP，终端在PDCCH结束后和PDSCH传输开始前完成BWP切换，切换总时间是PDCCH解析时间和BWP切换时间，BWP切换行为发生在PDCCH所在时隙内PDCCH监听之后。
对于下行信道到上行信道的BWP切换，终端利用上下行信道的转换间隔完成BWP切换操作。
对于上行信道到下行信道的BWP切换，终端在上行BWP的最后一个时隙的最后M个符号进行BWP切换。
