Abstract: A method for performing beam failure recovery (BFR) in a user equipment in a wireless communication system is disclosed. The method comprises performing a contention free random access procedure for BFR using a first beam during a BFR timer is running; and if the contention free random access procedure does not succeed until the BFR timer expires, performing a contention based random access procedure for BFR using a second beam selected from a beam set, wherein the first beam is excluded from the beam set.

Abstract: A method and a 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 therein suggests a method for performing multiplex transmission when base stations within a network are synchronized. Particularly, a terminal receives, from a first base station, control information for the transmission of an M number of transmission blocks. The control information includes information for allocating multiplex transmission resources available for the first base station and a second base station during a predetermined subframe. The terminal receives the M number of transmission blocks from the first base station and the second base station via the multiplex transmission resources. Here, the M number of transmission blocks receives from the first base station and the M number of transmission blocks received from the second base station are decoded by using the same reference signal.
