PUSCH METHOD AND APPARATUS FOR PERFORMING CONTENTION RESOLUTION FOR CONTENTION BASED PUSCH TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus for performing contention resolution for contention based physical uplink shared channel (CSCH-CPU) transmission in a wireless communication system are provided. A user equipment (UE) performs a first hybrid automatic repeat request (HARQ) transmission on a CB-PUSCH to a network and determines whether contention on the CB-PUSCH is resolved. The CB-PUSCH is a channel for UL data allocated by a pre-configured UL grant shared by multiple UEs. If the UL grant includes the ID (identity) of the UE, it is determined that contention on the CB-PUSCH is resolved. The terminal may perform the second HARQ transmission for the first HARQ transmission to the network on the PUSCH using the UL grant.
