The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate than 4G communication systems such as LTE systems. A method performed by a user equipment (UE) in a wireless communication system may comprise receiving a signal, converting the signal into a digital signal, receiving, from a base station, transmission spectrum information for the UE and information for a time window, estimating a timing skew and a reception signal-to-noise ratio (SNR) of the digital signal based on the information for the time window and the transmission spectrum information, and compensating for a distortion of the digital signal based on the estimated timing skew and the reception SNR.

Method and apparatus for processing signal in wireless communication system

The present application provides a method for allocating resources in a wireless communication system using multiple antennas. The method for allocating resources comprising: transmitting a reference signal to first-type terminals based on type information of a plurality of terminals; receiving channel estimation information from the first-type terminals that have received the reference signal; generating beams based on the received channel estimation information; and allocating resources for the generated beams. First-type beams for the first-type terminals are primarily generated and allocated, and on the basis of the generated first-type beams, second-type beams for second-type terminals may be non-orthogonally generated and allocated when the resources for the beams are allocated.

Method and device for selecting multiple users and allocating resources for non-orthogonal multiple access in wireless communication system

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.

Method and device for transmitting and receiving signal in multi-cell cooperative communication system

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.

Method for transmitting and receiving signal in multi-cell cooperative communication system and apparatus therefor

According to one embodiment of the present invention, a method of transmitting feedback information by a base station supporting multi-user multi-input multi-output (MU-MIMO) to a network entity includes obtaining a projection matrix based on channel information estimated for multiple channels between antennas of the base station and each of user equipments, projecting at least one of the channel information and uplink data received from the user equipments to a second space from a first space using the projection matrix and transmitting feedback information including at least one of the projected channel information and the projected uplink data to the network entity.

Method of transceiving feedback information in wireless communication system and apparatus therefor

The present description relates to a method of using a terminal to adaptively feed back channel information relating to multi-cell cooperative communication includes: measuring an average signal-to-noise ratio of a virtual multi-antenna channel between a terminal and at least one cell to transmit same to a base station; receiving, from a base station, a number of allowable feedback bits determined on the basis of the average signal-to-noise ratio and cooperative communication information; selecting a codebook from a plurality of predetermined codebooks on the basis of the number of allowable feedback bits and the cooperative communication information; and quantizing channel information on a virtual multi-antenna channel using the selected codebook, and transmitting feedback information including the quantized channel information to a base station. The codebook may be selected to transmit the feedback information using the entire number of allowable feedback bits.
