Method and apparatus for transmitting and receiving reference signal in wireless communication system

摘要

The present invention relates to a wireless communication system and, more specifically, to a method and an apparatus for transmitting and receiving a reference signal (RS). The method for enabling user equipment (UE) of the wireless communication system to transmit an uplink signal according to one embodiment of the present invention comprises the steps of: receiving information on candidates of a first parameter set used for generating a sequence of a first RS; and generating and transmitting a sequence of a second RS using a second parameter set determined among the candidates of the first parameter set.

1. A method for transmitting an uplink (UL) signal by a User Equipment (UE) in a wireless communication system, the method comprising:
receiving, via radio resource control (RRC) signaling, information about a plurality of downlink (DL) parameter set candidates, each of the DL parameter set candidates including a virtual cell identifier (VCI) and a sequence shift offset (Δss) used to generate a sequence of a DL Reference Signal (RS); receiving, via a physical downlink control channel (PDCCH), downlink control information (DCI); and generating and transmitting a sequence of a UL RS according to the uplink grant, using a UL parameter set determined based on the DL parameter set candidates, wherein the DCI includes a field indicating a DL parameter set among the plurality of DL parameter set candidates, and wherein in generating the sequence of the UL RS, a VCI and a sequence shift offset (Δss) in the UL parameter set are obtained from a VCI and a sequence shift offset (Δss) in the DL parameter set indicated by the DCI.
