可选地，所述信息域占用1比特。
下面给出具体实施例的举例说明。
实施例一：
调度信息中的一个信息域为1比特，用于指示上行物理信道(当然也可以为下行物理信道)是否开启跳频或者用于指示VRB类型。UE确定上行物理信道的波形为CP-OFDM或者DFT-s-OFDM。当UE确定上行物理信道的波形为DFT-s-OFDM时，则所述1比特信息域用于指示上行物理信道是否开启跳频；当UE确定上行物理信道的波形为CP-OFDM，则所述1比特信息域用于指示VRB类型为集中式VRB或者分布式VRB。
例1.1：
UE根据剩余最小***信息(Remaining Minimum System Information，RMSI)的通知，确定随机接入信道(Random Access Channel，RACH)消息3的波形为DFT-s-OFDM或者CP-OFDM。
UE接收随机接入响应消息，其承载的用于RACH消息3授权中的一个1比特信息域，用于指示RACH消息3是否跳频或者用于指示VRB类型。具体地，若UE确定RACH消息3的波形为DFT-s-OFDM，则RACH消息3授权中的一个1比特信息域，用于指示RACH消息3是否开启跳频；若UE确定RACH消息3的波形为CP-OFDM，则RACH消息3授权中的一个1比特信息域，用于指示RACH消息3的VRB类型为集中式VRB或者分布式VRB。例1.2：
用于上行数据信道PUSCH或者上行控制信道PUCCH资源分配的下行控制信息(Downlink Control Information，DCI)中的一个1比特信息域，用于指示PUSCH/PUCCH是否跳频或者用于指示VRB类型。UE根据网络侧高层信令的配置或者物理层信令的通知，确定PUSCH/PUCCH的波形为DFT-s-OFDM或者CP-OFDM。若UE确定PUSCH/PUCCH的波形为DFT-s-OFDM，则DCI的一个1比特信息域用于指示PUSCH/PUCCH是否开启跳频；若UE确定PUSCH/PUCCH的波形为CP-OFDM，则DCI中的一个1比特信息域用于指示PUSCH/PUCCH的VRB类型为集中式VRB或者分布式VRB。
实施例二：
UE确定上行物理信道的波形为CP-OFDM或者DFT-s-OFDM。若波形为CP-OFDM，则调度信息指示上行物理信道是否跳频和/或VRB类型。若波形为DFT-s-OFDM，则调度信息指示上行物理信道是否跳频。
针对波形为CP-OFDM，具体地，例如分别采用1比特指示是否开启跳频以及VRB类型；或者对是否跳频以及VRB类型联合编码，采用2比特指示。或者，UE根据网络侧通知确定调度信息中仅指示是否跳频或者仅指示VRB类型。例如，当网络侧通知UE调度信息仅指示是否跳频时，调度信息中的1比特信息域用于指示上行物理信道是否跳频；而当网络侧通知UE调度信息仅指示VRB类型时，所述信息域用于指示集中式VRB或者分布式VRB分配。
