Communication method and communication device

Provided are a communication method and a communication device, the method comprising: a terminal device receiving first information from a network device, the first information being used for configuring M communication parameter groups corresponding to N candidate carriers; and the terminal equipment receives second information from the network equipment, wherein the second information is used for indicating at least one communication parameter group in the M communication parameter groups. And the terminal equipment communicates on the at least one carrier according to the at least one communication parameter group. The flexibility of changing the communication mode of the terminal equipment is improved, and the time delay of changing the communication mode is reduced. 本申请提供了一种通信方法和通信装置，该方法包括：终端设备接收来自网络设备的第一信息，该第一信息用于配置N个候选载波对应的M个通信参数组。终端设备再接收来自该网络设备的第二信息，该第二信息用于指示该M个通信参数组中至少一个通信参数组。终端设备根据该至少一个通信参数组，在该至少一个载波上通信。提高了变更终端设备的通信方式的灵活性，减小通信方式变更的时延。
