METHOD AND APPARATUS FOR DEVICE-TO-DEVICE HARQ PROCESS MANAGEMENT
Abstract:
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 Long Term Evolution (LTE). A method and an apparatus that may repeatedly transmit signals to cope with and reduce transmission errors in device-to-device (D2D) communication are provided. The method includes receiving, upon generation of data to be transmitted to a receiving user equipment (UE) (RX UE), allocation of resources to be used for D2D communication, transmitting a scheduling assignment (SA) containing identification information of at least one RX UE to the at least one RX UE, assigning at least one hybrid automatic repeat request (HARQ) process for the identification information of the at least one RX UE, and transmitting data to the at least one RX UE based on the HARQ process. Accordingly, it is possible to remove factors causing system performance degradation when retransmission operation for communication between a UE and a base station (eNB) is introduced to D2D communication.
