1. A method for wireless communication, performed by a terminal, the method comprising:
determining, from at least two listen-before-talk (LBT) frequency bands, a first LBT frequency band on which channel listening is successful; and
sending an uplink communication message on a first physical uplink control channel (PUCCH) on the first LBT frequency band;
determining, from other LBT frequency bands, the first LBT frequency band on which channel listening is successful, in response to a failure of channel listening on a second LBT frequency band, and sending the uplink communication message on the first PUCCH; and
sending the uplink communication message on a second PUCCH, in response to successful channel listening on the second LBT frequency band, wherein the terminal is configured with the second PUCCH for sending the uplink communication message, and the second PUCCH is configured to correspond to the second LBT frequency band;
wherein a first relative time-frequency resource position of the first PUCCH relative to the first LBT frequency band is the same as a second relative time-frequency resource position of the second PUCCH relative to the second LBT frequency band.
