US 10,833,735 B2 · Method and device for receiving signal in wireless communication system to which multiplex transmission technique is applied

Abstract

A method and device for receiving a signal in a wireless communication system to which a multiplex transmission technique is applied are provided. The wireless communication system proposed herein suggests a method for increasing the receipt reliability of a terminal with respect to a multiplex transmission activation indicator indicating the start of multiplex transmission. Particularly, a terminal checks the receipt of a multiplex transmission activation indicator transmitted, from a first base station, for every predetermined subframe. If the terminal succeeds in receiving the multiplex transmission activation indicator, an ACK signal associated with the multiplex transmission activation indicator is transmitted to the first base station. Here, the multiplex transmission activation indicator indicates that the first base station and a second base station are capable of transmitting the same data for a predetermined time together.

monitoring reception of a multi-path transmission activation indicator being transmitted from a first base station at each predetermined subframe;
and
based on a user equipment (UE) successfully receiving the multi-path transmission activation indicator, transmitting an acknowledgement (ACK) signal for the multi-path transmission activation indicator to the first base station,
wherein the multi-path transmission activation indicator indicates that the first base station and the second base station are capable of transmitting the same data during a predetermined time,
wherein the multi-path transmission activation indicator is transmitted by using a sequence, and
wherein the method further comprises calculating an auto-correlation value of the sequence,
wherein, based on the calculated auto-correlation value of the sequence being equal to or greater than a threshold value, the multi-path transmission activation indicator is acknowledged to be successfully received.
