The present disclosure discloses a method and device for channel selection. The method comprises: indicating a time-domain resource position and a frequency-domain resource position of an extended physical uplink control channel region based on a common physical downlink control channel; and instructing a group of user terminals to transmit an extended physical uplink control channel in the extended physical uplink control channel region which has been indicated, wherein different user terminals each transmit the extended physical uplink control channel in different extended physical uplink control channel regions which have been indicated. The present disclosure solves a technical problem of a larger downlink signaling cost resulted from the uplink scheduling authorization when a larger number of users transmit data in the extended physical uplink control.
