Abstract
The disclosure relates to a communication technique and a system for fusing a 5G communication system with IoT technology to support a higher data rate after a 4G system. The disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.), based on 5G communication technology and IoT-related technology.
Claims15
A method performed by a terminal in a communication system, the method comprising:
- receiving, from a base station, a physical uplink control channel (PUCCH) configuration and a physical downlink shared channel (PDSCH) configuration, the PUCCH configuration including information on a number of slots and information on a length of a subslot;
- receiving, from the base station, downlink control information (DCI) including resource allocation information;
- receiving, from the base station, data based on the PDSCH configuration and the resource allocation information;
- and
- performing repetition of PUCCH transmission for the data over N slots including a number of symbols indicated by the length of the subslot based on the PUCCH configuration, wherein N indicates the number of slots,
- wherein the repetition of the PUCCH transmission is performed based on alternating between multiple transmission and reception points (TRPs) per L repetitions of the PUCCH transmission, and
- wherein an offset between the repetition of the PUCCH transmission is identified based on the PUCCH configuration.
