Abstract: The disclosure relates to a communication technique for merging internet of things (IoT) technology with a 5th generation (5G) communication system for supporting a data transmission rate higher than that of a 4th generation (4G) system, and a system therefor. The disclosure is applied to intelligent service based on 5G communication technology and IoT-related technology. A method for enhancing physical uplink control channel (PUCCH) reception performance, and a device therefor are provided. The method includes receiving, from a terminal, a signal for determining environment information of the terminal, identifying the environment information of the terminal based on the signal, identifying resource allocation information for a physical uplink control channel (PUCCH) format 1 signal based on the environment information of the terminal, transmitting the resource allocation information to the terminal, and receiving the PUCCH format 1 signal from the terminal based on the resource allocation information.

Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than 4th generation (4G) communication systems such as long-term evolution (LTE). The present disclosure is for managing uplink control channels in a wireless communication system, and an operation method for a base station may include the steps of: allocating an uplink control channel of a first format to a first terminal; allocating an uplink control channel of a second format to a second terminal on the basis of a resource of the first format; and transmitting information about the uplink control channel allocation.

Abstract: Embodiments of the present disclosure relate to control channel transmission in a wireless communication system thereof are provided. The method, executed by a processor in user equipment (UE) or a base station (BS), may include acquiring information bits for uplink control information; acquiring a transmission bitstream, the transmission bitstream being based on channel coding and scrambling for the information bits; generating a transmission complex sequence corresponding to the transmission bitstream, the transmission complex sequence being from among a plurality of complex sequences; and transmitting a signal of the transmission complex sequence to a base station (BS) through a physical uplink control channel (PUCCH), wherein each of the plurality of complex sequences is based on a respective Zadoff-Chu (ZC) sequence, and a respective length of the ZC sequence is larger than a number of candidate values of the transmission bitstream.
