Claim of US Patent No. 10,397,952

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:performing a first hybrid automatic repeat request (HARQ) transmission, on a contention based physical uplink shared channel (CB-PUSCH), to a network;
receiving a UL grant on a physical downlink control channel (PDCCH) from the network,
wherein the UL grant includes an identity of the UE;
determining that contention on the CB-PUSCH is resolved based on the identity of the UE; and
performing a second HARQ transmission for the first HARQ transmission, on a non-contention PUSCH, to the network based on the UL grant,
wherein the CB-PUSCH is a channel for UL data allocated by a pre-configured UL grant which is shared by multiple UEs.
