摘要： A method and apparatus are presented for transmitting a signal in accordance with an adaptive blind interference alignment (BIA) scheme in a wireless access system. A transmitter configures a first block including desired signals and interference signals on the basis of a number of receivers within a cell and a number of reception modes of the receivers. Further, the transmitter configures a second block including either the desired signals or the interference signals, and configures alignment blocks for each of the receivers by combining the first block with the second block. The transmitter transmits the alignment blocks to the receivers in accordance with transmission symbol patterns corresponding to the alignment blocks. Symbol vectors included in the alignment blocks for each of the receivers are configured to be overlapped between the receivers.

摘要： The present invention relates to a method of transmitting and receiving a signal in a wireless communication system. In particular, in a time division multi-cell cooperative communication system, a base station may receive a reference signal, estimate a channel of each user terminal based on the reference signal, and determine a transmission and reception filter based on estimated channel information. The base station and a cooperative base station that cooperates with the base station may mutually exchange the reference signal and average signal power information on a terminal and determine the transmission and reception filter based on exchanged information.

摘要： The present invention relates to a method for transmitting and receiving signals in a wireless communication system. Specifically, in a multi-cell cooperative communication system, a base station can form cooperative detection user set information by detecting a terminal within a cell and form cooperative processing user set by receiving the cooperative detection user set information of a neighboring base station. At this time, the base station acquires information about a base station adjacent to the neighboring base station and designs an efficient filter in transmitting and receiving signals of terminals between the base stations, thereby being capable of removing inter-cell interference signals.

摘要： A method of performing, by a user equipment (UE), a random access procedure in a wireless communication system is disclosed. The method includes receiving configuration information related to the random access procedure, transmitting a random access preamble and a physical uplink shared channel (PUSCH), and receiving a random access response (RAR) message. The PUSCH is transmitted based on a predetermined PUSCH transmission power. The predetermined PUSCH transmission power is based on preamble reception power information related to a transmission of the random access preamble and a specific offset.
