Abstract: In this disclosure, methods for pre-compensation of the phase shifting error, and apparatuses for the same are disclosed. In one example, a device performs precoding of a digital signal, while acquiring information on an error caused by a phase shifting of the precoding. Then, the device performs phase compensation on the digital signal based on the acquired information. This phase compensated-digital signal is converted to an analog signal, and is transmitted to a receiver.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a wireless communication system. The present invention relates to a method for transmitting ACK/NACK in a wireless communication system in which carrier aggregation is set, and an apparatus therefor. Specifically, the present invention relates to an ACK/NACK transmission method and an apparatus therefor, the method comprising the steps of: receiving information on a plurality of physical uplink control channel (PUCCH) resources via upper layer signaling; receiving a transmit power control (TPC) field on a secondary carrier through a physical downlink control channel (PDCCH); receiving data indicated by the PDCCH; and transmitting ACK/NACK for the data, wherein the ACK/NACK is transmitted using a PUCCH resource which is indicated by the value of the TPC field among the plurality of PUCCH resources.

Abstract: A method for transmitting feedback information for fractional beamforming using a massive antenna array from a User Equipment (UE) to a Base Station (BS) in a wireless communication system is disclosed. The method includes receiving information about a plurality of Reference Signal (RS) resources from the BS; selecting at least one of a sub-precoder for at least one RS resources, and one linking precoder for linking the RS resources, based on a preset codebook; and reporting information about the selected precoder to the BS. The selected precoder is one precoding matrix of precoding matrices included in the codebook or a permuted form of the one precoding matrix, and the information about the selected precoder includes an index and permutation information of the one precoding matrix.

Abstract: A method for transmitting channel status information (CSI) of downlink multi-carrier transmission includes generating the CSI including at least one of a rank indicator (RI), a first precoding matrix index (PMI), a second PMI and a channel quality indicator (CQI) for one or more downlink carriers, the CQI being calculated based on precoding information determined by a combination of the first and second PMIs, determining, when two or more CSIs collide with one another in one uplink subframe of one uplink carrier, a CSI to be transmitted on the basis of priority, and transmitting the determined CSI over a uplink channel. If a CSI including an RI or a wideband first PMI collides with a CSI including a wideband CQI or a subband CQI, the CSI including a wideband CQI or a subband CQI has low priority and is dropped.
