Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method for transmitting uplink control information, including: determining, by a user equipment (UE), at least two carriers for uplink transmission in a cell currently connected by the UE, and determining a carrier for uplink control information (UCI) transmission from the at least two carriers for uplink transmission; determining, by the UE, a relative frequency-domain position and a time-domain starting position occupied by UCI on the determined carrier for UCI transmission; and retuning, by the UE, a center radio frequency of the UE to a center frequency of the carrier for UCI transmission, and transmitting the UCI according to the relative frequency-domain position and the time-domain starting position occupied by the UCI; in which, the UE receives and transmits information on one carrier at one time. Using the present disclosure can efficiently transmit UCI. The present disclosure further discloses a method for requesting random …
