    Abstract: The method for feedback of channel quality information in a wireless communication system, according to one embodiment of the present invention, is performed by a terminal and comprises the steps of: receiving feedback configuration information, including information on disjoint segmentation indicating the indexes of channel or beam quality-related parameters for broadcast or multicast services, from a base station; and according to the information on disjoint segmentation in the feedback configuration information, encoding the index of a channel or beam quality-related parameter to be reported and transmitting same to the base station, wherein the disjoint segmentation includes multiple subsets which do not overlap and which have different lengths, and the index of the channel or beam quality-related parameter, which is transmitted to the base station, may indicate a predetermined value in one subset among the multiple subsets.

    Abstract: A method for a terminal for detecting data transmitted according to the multiuser superposition transmission system comprises the steps of: receiving, from a base station, downlink control information comprising information for a codeword subset selected form a non-orthogonal codebook comprising an orthogonal subset and non-orthogonal subset; estimating a channel on the basis of a reference signal symbol or reference signal pattern corresponding to the selected codebook subset; and, on the basis of the channel estimation, detecting desired data symbols on the basis of the selected codebook subset, wherein the superposed data symbols are symbols comprising data not only for the terminal but also for other terminals.

    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 terminal receives, from a base station, information relating to a predefined codeword for non-orthogonal multiple access. The predefined codeword includes a first spreading code and a second spreading code. The terminal configures a base layer using the first spreading code and configures an enhancement layer using the second spreading code. The terminal transmits a terminal identifier and data to the base station through a competition-based resource which overlappingly uses the base layer and the enhancement layer, wherein the terminal identifier is transmitted through the base layer and the data is transmitted through the enhancement layer.
