The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for transmitting data in a base station (BS) in a communication system is provided. The method includes transmitting data to a plurality of stations (STAs) included in a group on a first sub-frame based on a schedule preset based on a time division duplexing (TDD) scheme; and receiving acknowledgement (ACK) signals from each of the plurality of STAs on a second sub-frame after a first interval from the first sub-frame.

Method and apparatus for transmitting and receiving in communication system

The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). A terminal apparatus in a wireless communication system is provided. The terminal apparatus includes a transceiver configured to transmit and receive a signal, and at least one processor configured to be functionally combined with the transceiver, control the transceiver to transmit a scheduling request (SR) signal by using a pre-allocated resource from a base station, and control the transceiver to transmit uplink (UL) data for a first service by using a resource punctured in a downlink (DL) subframe for a second service, and the pre-allocated resource includes a resource allocated in the DL subframe for the second service.

Apparatus and method for multiplexing data in wireless communication system

A 5Generation (5G) or pre-5G communication system for supporting a higher data rate than a 4G communication system such as Long Term Evolution (LTE) is provided. A method of an evolved Node B (eNB) can include detecting a collision caused by first data received from a first terminal in a time resource for contention-based uplink data transmission and second data received from a second terminal in the time resource, determining a first delay value in first data retransmission using a dedicated scheduling scheme, and determining a second delay value in the first data retransmission using a contention-based uplink data transmission scheme, determining a scheme for retransmitting the first data based on the first delay value and the second delay value, and transmitting information indicating the determined scheme to the first terminal.
