Abstract: A communication method and apparatus are provided. The method includes: A terminal device sends first data to a network device through a first cell group in an activated state. The terminal device receives a first message from the network device, where the first message is used to deactivate the first cell group. The terminal device changes a state of the first cell group from the activated state to a deactivated state based on the first message of the network device. If the terminal device receives no success acknowledgment of the first data and/or there is second data that has not been transmitted in the first cell group, the terminal device retransmits the first data and/or sends the second data to the network device through a second cell group in an activated state.

Abstract: A wireless communication method includes determining a length of a ZC sequence based on a resource block quantity or a subcarrier quantity corresponding to a system bandwidth and determining a reference signal sequence included in an uplink reference signal based on the length of the ZC sequence and a resource block quantity or a subcarrier quantity corresponding to an allocated user bandwidth that is a part of the system bandwidth. When different communications devices use the same system bandwidth for communication, reference signal sequences used by the different communications devices correspond to the same ZC sequence length. The ZC sequence length is exclusively designed for a resource block quantity or a carrier quantity of the system bandwidth. Generation of the reference signal sequences is related to mapped locations of the reference signal sequences. Therefore, reference signal sequences used by different communications devices have a relatively high cross correlation.
