Abstract: Disclosed is a wireless data transceiving method in a multi-point transmission environment. A data transmitting method of a base station includes determining priorities of a plurality of terminals, allocating a symbol to be transmitted to a low-priority terminal to a base layer, allocating a symbol to be transmitted to a high-priority terminal to an enhancement layer, performing hierarchical modulation, and transmitting the hierarchically modulated symbol. Accordingly, by combining CoMP transmission technology and hierarchical modulation, a data capacity for a cell edge terminal increases and necessary resources decrease.

Abstract: Disclosed is a method for configuring a bandwidth for supporting a broadband carrier in a communication system. An operation method of a base station comprises the steps of: configuring a first bandwidth part and a second bandwidth part for a terminal; configuring a reserved resource for the first bandwidth part in a resource area in which the first bandwidth part and the second bandwidth part overlap; and performing an operation of transmitting or receiving a second data channel, which is scheduled to the second bandwidth part, together with the terminal by using the reserved resource. Therefore, the performance of the communication system can be improved.

Abstract: In a communications system using a plurality of beams, a terminal determines a beam to be communicated with the terminal among the plurality of beams, determines one sequence among sequences allocated to the determined beam as a beam based random access preamble, and transmits the beam based random access preamble through the determined beam. In addition, if a random access response for the beam based random access preamble is not received from a base station for a set interval, the terminal determines one sequence among sequences in a cell based random access preamble collection as a cell based random access preamble and transmits the cell based random access preamble.
