Abstract: Provided are a method and an apparatus for competition-based transmitting of uplink data in a wireless communication system to which a non-orthogonal multiple access scheme is applied. Particularly, a UE receives, from a base station, information relating to a contention zone. The information relating to the contention zone includes predefined contention zone patterns and predefined terminal classes. The terminal selects a terminal class for the terminal from among the predefined terminal classes. The terminal selects a contention zone pattern for the terminal from among the predefined contention zone patterns on the basis of the selected terminal class. The uplink data is transmitted to the base station through a plurality of contention zones included in the selected contention zone pattern.

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.
