Abstract: A method for indicating a combination between a codeword and a layer in a MIMO communication, system, a layer mapping method, and a data transmission method using the same are disclosed. A minimum number of codeword-layer mapping combinations from among all available combinations based on the’ numbers of all codewords and all layers are pre-defined in consideration of a ratio of a codeword to a layer, a reception performance of a receiver, and reduction of combinations, so that a data transmission method using the predefined combinations is implemented. If a. specific one codeword is mapped to at least two layers, a diversity gain can be acquired.

Abstract: Provided are a method for a terminal for carrying out uplink communication in a wireless communication system, and an apparatus using the method. The method receives an uplink communication-related parameter independently configured for each analog beam, and carries out the uplink communication on the basis of the parameter. If the uplink communication is carried out using a particular analog beam, then an uplink communication-related parameter configured on the particular analog beam is applied to the uplink communication.
