Abstract

A receiving control method includes: receiving downlink information transmitted by a base station, at least after a round-trip time between the terminal and the base station after transmitting uplink information to the base station. The round-trip time may correspond to a moment of completing a transmission of the uplink information. The uplink information may be a first message of a random access procedure, a physical uplink channel for transmitting a preconfigured uplink resource, a first transmission among multiple uplink transmissions, or feedback information carrying a downlink hybrid automatic retransmission request.
