Abstract: A method for transmitting and receiving, by a user equipment (UE), a phase noise compensation reference signal (PCRS) in a wireless communication system is disclosed. The method includes receiving, from a base station, control information related to a transmission of a downlink data, the control information including at least one of a precoding scheme related to the downlink data, a number of transmission ranks, or a modulation and coding scheme (MCS) level; checking a transmission location of a demodulation reference signal (DM-RS) for demodulating the downlink data based on the received control information; and receiving, from the base station, the PCRS on at least one symbol after a transmission symbol of the DM-RS considering the checked transmission location of the DM-RS.

Abstract: A method of transmitting, by a terminal, a phase noise compensation reference signal in a wireless communication system is discussed. The method includes determining a frequency resource and a time resource of a demodulation reference signal (DM-RS); mapping the phase noise compensation reference signal to a frequency resource and a time resource based on the determined frequency resource and the time resource of the DM-RS; and transmitting, to a base station, the phase noise compensation reference signal on the mapped frequency resource and the time resource of the phase compensation reference signal. Further, a location of a phase noise compensation reference signal symbol in the time resource is determined based on a location of a DM-RS symbol in the time resource of the DM-RS.

Abstract: Provided are a method and a device for transmitting data in a wireless communication system. More particularly, a terminal transmits a first transmission preamble and a second transmission preamble so as to estimate an uplink channel. If a common temporary identifier is assigned to the first and second transmission preambles, a common response message for the first and second transmission preambles is received. If temporary identifiers that are different from each other are respectively assigned to the first and second transmission preambles, respective individual response messages for the first and second transmission preambles are received. Data is transmitted by means of an estimated uplink channel. The first transmission preamble is transmitted in a plurality of resource regions, and the second transmission preamble is transmitted in one resource region.

Abstract: Provided are a method and an apparatus for transmitting, on the basis of a repeating pattern, a synchronization signal in a wireless communication system. A base station divides a cell into multiple sectors and transmits multiple types of synchronization signals, which respectively correspond to the multiple sectors and have different repeating patterns, to a terminal through a system frame. The terminal performs detection of the multiple types of synchronization signals having the different repeating patterns and determines the position of the terminal within the cell according to the detected synchronization signals.

Abstract: The present document is for a wireless communication using multiple antenna units based on new virtual user equipment (virtual UE) concept. A user equipment (UE), according to the present invention, receives service from a network in a wireless communication system by registering multiple antenna units of the UE as two or more virtual UEs with a first network entity of the network, wherein the first network entity is a network node for physical radio link control; and receiving the service from the network by the two or more virtual UEs. The two or more virtual UEs of the UE are recognized as one UE by network entities of the network other than the first network entity.
