1. A method of transmitting or receiving signals by a first user equipment (UE) in a wireless communication system, the method comprising:
receiving information about a resource for uplink (UL) control information transmission and a multiple access (MA) signature configuration;
determining, based on the resource for the UL control information transmission, whether the resource allocated for the UL control information transmission overlaps a resource allocated for UL data transmission in time;
determining whether to perform transmission in orthogonal multiple access (OMA) or non-orthogonal multiple access (NOMA) based on the received information when it is determined that the resource allocated for the UL control information transmission overlaps the resource allocated for the UL data transmission in time;
determining whether to multiplex the UL control information based on a priority of information included in the UL control information, if it is determined to perform transmission in NOMA; and
if it is determined to multiplex the UL control information, multiplexing the UL control information with UL data based on the information about the MA signature configuration and transmitting a result of the multiplexing, as a second UE transmits UL control information of the second UE on the resource for the UL control information of the first UE without multiplexing the UL control information of the second UE with the UL data of the second UE.
