Abstract:
1. A method for a user equipment (UE) to transmit uplink data to a base station, the method comprising: receiving, from the base station, a downlink control signal including scheduling information for the uplink data transmission; trying to decode the downlink control signal in a unit which size corresponds to a multiplication of an integer value, selected from among predetermined multiple integer values, by a predetermined frequency domain size unit for a transmission of the downlink control signal, wherein the predetermined multiple integer values correspond to integer values of multiple downlink control signal transmission formats, wherein a smallest time-frequency resource element is defined by one subcarrier in a frequency domain and one orthogonal frequency division multiplexing (OFDM) symbol in a time domain, wherein the predetermined frequency domain size unit for the transmission of the downlink control signal is predetermined to comprise a plurality of the smallest time-frequency resource element arranged in the frequency domain at one OFDM symbol; and transmitting the uplink data to the base station according to the scheduling information of the downlink control signal, upon decoding the downlink control signal.
