Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method whereby a terminal transmits hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative ACK (NACK) information corresponding to downlink data received from a corresponding base station is provided.

Claims

1. A method performed by a terminal in a wireless communication system, the method comprising:

receiving a plurality of offset parameters from a base station;

identifying an offset associated with a physical uplink shared channel (PUSCH) based on a number of bits of hybrid automatic repeat request (HARQ) acknowledgement (ACK) information, the offset corresponding to at least one of the plurality of the offset parameters;

identifying a number of coded modulation symbols based on the identified the offset associated with the PUSCH; and

transmitting, to the base station, uplink control information (UCI) on the PUSCH based on the identified number of the coded modulation symbols.

2. The method of claim 1,

wherein the offset associated with the PUSCH includes a HARQ ACK offset, and
