FIELD: radio engineering, communication.
SUBSTANCE: invention relates to techniques for monitoring grant channels in a wireless communication network. In one version, user equipment (UE) determines whether a monitoring condition is satisfied, monitors at least one grant channel for granting radio resources if the monitoring condition is satisfied, and stops monitoring the at least one grant channel if the monitoring condition is not satisfied. The UE may determine that the monitoring condition is satisfied after sending scheduling information indicating that there is data to send, if there is a current grant of radio resources, if a grant of radio resources is expected, if there is at least one scheduled flow and a data buffer for the scheduled flow(s) is not empty, if there is a current grant of radio resources and data transmission has been sent using this grant of radio resources, if there is at least one other control channel to monitor, etc.
EFFECT: saving power and prolonging operation in standby and talk modes.
