Abstract
The invention provids a reference signal transmitting method and device in multi-antenna system. Terminal generate is respectively distributed with different cyclic shift values of a plurality of reference signal sequence generating the mapping a plurality of reference signal sequence of the orthogonal frequency division multiplexing (OFDM) symbol and via a plurality of antennas to the base station transmitting OFDM symbol. Based on cyclic displacement field indicates transmitting through physical downlink control channel (PDCCH) of the parameter n determining the each cyclic shift value of each reference signal sequence distributed by the task source device.
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).
