Abstract:
1. A method for transmitting, by a base station, configuration information for a reference signal for channel measurement, the method comprising: transmitting, to a user equipment: 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, wherein the first subframe is comprised of two slots—slot 0 and slot 1, each of which includes 7 orthogonal frequency division multiplexing (OFDM) symbols—OFDM symbols 0 to 6, the first reference signal time-frequency resource is within two OFDM symbols in the first subframe, and the two OFDM symbols are other than OFDM symbols 0, 1, 2 and 4 of the slot 0 and OFDM symbols 0, 1 and 4 of the slot 1, and wherein the second subframe is comprised of two slots—slot 0 and slot 1, each of which includes 7 orthogonal frequency division multiplexing (OFDM) symbols—OFDM symbols 0 to 6, the second reference signal time-frequency resource is within two OFDM symbols in the first subframe, and the two OFDM symbols are other than OFDM symbols 0, 1, 2 and 4 of the slot 0 and OFDM symbols 0, 1 and 4 of the slot 1.
