One technique includes determining ACK parameter(s) to be used for acknowledging a bundled transmission that includes instance(s) of a channel across subframe(s). An indication of the ACK parameter(s) is signaled to a user equipment (UE). The ACK parameter(s) include a first ACK parameter that conveys a size of the bundled transmission and a second ACK parameter that conveys an amount of time for the UE to delay acknowledging a data transmission in an instance of the channel after receiving the data transmission. The UE may acknowledge the bundled transmission in accordance with the ACK parameter(s).

A wireless communication device that communicates with a plurality of slave units, including: a transmitter that transmits a data transmission instruction including a first identification information of a single slave unit among the plurality of slave units; a receiver that receives data corresponding to the data transmission instruction from the single slave unit; wherein the transmitter transmits to the plurality of slave units acknowledgment data which has incorporated second identification information into an acknowledgment to the data received from the single slave unit, the second identification information indicating another slave unit which transmits data corresponding to a next data transmission instruction to the wireless communication device.

Provided is a method by which a first apparatus performs wireless communication and an apparatus for supporting the method. The method comprises the steps of: receiving, from a base station, information related to a sidelink (SL) bandwidth part (BWP); receiving, from the base station, information related to an uplink (UL) BWP; receiving, from the base station, information related to an SL resource and information related to a UL resource for reporting a hybrid automatic repeat request (HARQ) feedback; transmitting, on the basis of the SL resource within the SL BWP, data in which the HARQ feedback has been disabled to a second apparatus through a physical sidelink shared channel (PSSCH); generating an ACK related to the transmission of the data in which the HARQ feedback has been disabled; and transmitting, to the base station, the ACK on the basis of the UL resource within the UL BWP.

The present disclosure relates to a communication technique that merges IoT technology with a 5G communication system for supporting higher data transmission rates than 4G systems, and a system for same.
