Patent ID: 11064471

Abstract:
A communication method and a system for supporting a high data transmission rate are provided. The method and system fuses 5G communication systems with IoT technology to transmit data at a high rate after 4G systems. The communication method and system are applied to intelligent services, based on 5G communication technology and IoT related technology, for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, safety-related services, etc. The method for transmitting control information by a user equipment (UE) includes generating uplink control information (UCI), identifying whether a physical uplink shared channel (PUSCH) is not configured to transmit on a primary cell (PCell), identifying whether the PUSCH is configured to transmit on at least one secondary cell (SCell) for licensed band, and transmitting, to a base station, the UCI according to the identification.
