METHOD FOR TRANSMITTING AND RECEIVING UE-SPECIFIC REFERENCE SIGNAL AND APPARATUS FOR SAME

摘要

Disclosed are a method for transmitting and receiving a UE-specific reference signal and an apparatus for same. A method for a base station transmitting the UE-specific reference signal in a wireless communication system, according to one embodiment of the present invention, comprises a step of the base station transmitting the UE-specific reference signal to the UE by using a pre-determined pattern, wherein the predetermined pattern can be a pattern which is mapped onto an RE, in which the UE-specific reference index is an index including symbol indexes 0, 3 and 6 from an even-numbered index slot within one resource block (RB), or mapped onto an RE in which the UE-specific reference index is an index including symbol indexes 2 and 5 from an odd-numbered index slot within the RB.

1. A method for transmitting a user equipment (UE)-specific reference signal by a base station (BS) in a wireless communication system, the method comprising:
transmitting the UE-specific reference signal to a UE using a predetermined pattern, wherein the predetermined pattern is a pattern in which the UE-specific reference signal is mapped to reference elements (REs) corresponding to indices including symbol indices 0, 3 and 6 in an even-numbered index slot in one resource block (RB) and mapped to REs corresponding to indices including symbol indices 2 and 5 in an odd-numbered index slot in the RB.
