Abstract
Official abstract text for this publication.
Provided are a reference signal transmitting method and device in a multi-antenna system. A terminal generates a plurality of reference signal sequences to which different cyclic shift values are allocated, respectively, generates an orthogonal frequency division multiplexing (OFDM) symbol to which the plurality of reference signal sequences are mapped, and transmits the OFDM symbol to a base station through a plurality of antennas. Each cyclic shift value allocated to each reference signal sequence is determined on the basis of a parameter n indicated by a cyclic shift field transmitted from a physical downlink control channel (PDCCH).
First claim
Opening claim text (preview).
What is claimed is: 1. A method of transmitting a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH) in a wireless communication system, the method comprising: generating first and second DMRS sequences respectively associated with a first and second layer of a plurality of layers consisting of two layers, wherein first and second cyclic shifts are allocated to the first and second DMRS sequences, respectively; mapping the first and second DMRS seq…
