Abstract
An efficient Hybrid Automatic Repeat Request (HARQ) operation for low-latency and high-performance services in one radio access technology (RAT) in a wireless communication network is proposed. Under the proposed single HARQ operation scheme, an adaptive HARQ-ACK feedback timing is applied based on UE conditions and UE capability to support the tradeoff between low-latency and high-performance applications. In one embodiment, UE signals the network its HARQ-ACK timing capability. Furthermore, an adaptive number of HARQ processes is applied with a fixed HARQ soft buffer size because the hardware cost for HARQ soft buffer does not linearly increase with the number of HARQ processes. In one embodiment, UE determines a nominal HARQ soft buffer size and HARQ soft buffer size for each HARQ process based on a network-configured HARQ process number.
