Abstract: A method of performing contention based multiple access (MA) by a base station in a wireless communication system, includes receiving information regarding a best beam ID (identifier) from each user equipment (UE), allocating a resource for contention based multiple access per beam based on a number of best beam ID per beam obtained from the information regarding the best beam ID received from the each UE, and transmitting information regarding the resource for the contention based multiple access allocated per beam, to the each UE. In this case, an amount of the resource allocated for the contention based multiple access per beam is in proportion to the number of best beam ID per beam.

Abstract: A method of transmitting uplink control information (UCI) by a user equipment in a wireless communication system, includes the steps of receiving downlink control information (DCI) indicating a transmission time of the UCI through a prescribed frequency band in a first subframe, receiving a downlink data based on the DCI, and transmitting UCI associated with the downlink data in a second subframe based on the indicated transmission time of the UCI. In this case, the prescribed frequency band on which the DCI is transmitted is configured by a plurality of DCCUs (downlink control channel units) for transmitting the DCI, and the UCI may be transmitted on an UCCU (uplink control channel unit) in the second subframe, a frequency band of the first UCCU being same as a frequency band corresponding to a DCCU of a lowest frequency among the plurality of DCCUs.
