METHOD FOR TRANSMITTING REFERENCE SIGNALS IN A DOWNLINK MULTIPLE INPUT MULTIPLE OUTPUT SYSTEM

摘要

A method for transmitting, by a base station, configuration information for a reference signal for channel measurement. The method according to one embodiment includes transmitting, to a user equipment, first resource information for indicating a first pattern, first subframe information for indicating a first subframe, second resource information for indicating a second pattern, and second subframe information for indicating a second subframe. The first subframe information includes information indicating a first periodic interval, and the second subframe information indicates information indicating a second periodic interval. Each of the first and second subframes is comprised of two slots—slot 0 and slot 1, and each of the first and second reference signal time-frequency resources is within two OFDM symbols other than OFDM symbols 0, 1, 2, and 3 of the slot 0 and other than OFDM symbols 0, 1, and 3 of the slot 1.

1. A method for transmitting, by a base station, configuration information for a reference signal for a channel measurement, the method comprising:
transmitting, to a user equipment:
first resource information for indicating a first pattern configured for a first reference signal time-frequency resource of which transmission power is non-zero,first subframe information for indicating a first subframe which contains the first reference signal time-frequency resource corresponding to the first pattern,second resource information for indicating a second pattern configured for a second reference signal time-frequency resource of which transmission power is zero, andsecond subframe information for indicating a second subframe which contains the second reference signal time-frequency resource corresponding to the second pattern, wherein the first subframe information includes information indicating a first periodic interval with which the first subframe occurs, and the second subframe information indicates information indicating a second periodic interval with which the second subframe occurs, wherein each of the first and second periodic intervals corresponds to a plurality of subframes, and wherein each of the first and second subframes is comprised of two slots—slot 0 and slot 1, each of which includes 6 orthogonal frequency division multiplexing (OFDM) symbols—OFDM symbols 0 to 5 in case of an extended cyclic prefix, and each of the first and second reference signal time-frequency resources is within two OFDM symbols other than OFDM symbols 0, 1, 2, and 3 of the slot 0 and other than OFDM symbols 0, 1, and 3 of the slot 1.
