TRANSMISSION METHOD ON PHYSICAL UPLINK SHARED CHANNEL AND USER EQUIPMENT

Title:

TRANSMISSION METHOD ON PHYSICAL UPLINK SHARED CHANNEL AND USER EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2014/157979

Kind Code:

A1

Abstract:

The present application discloses a PUSCH transmission method. In the method, a UE receives configuration information from a base station, wherein the configuration information configures the UE to operate in a TDD reconfiguration mode of operation. Under the TDD reconfiguration mode of operation, the UE changes TDD uplink/downlink configuration according to an indication of the base station. The UE determines a timing relationship from UL Grant to PUSCH, a timing relationship from PHICH to PUSCH, and a timing relationship from PUSCH to PHICH, and detects the UL grant and/or PHICH according to the determined timing relationships. The UE sends PUSCH data based on the determined timing relationships according to the detected UL grant and/or PHICH. The present application also discloses a user equipment. By using this application, the UE can perform transmission on the PUSCH normally under the TDD reconfiguration mode of operation, transmit as much data as possible on the PUSCH of uplink subframes in case that the TDD uplink/downlink configuration changes frequently, and continue as many synchronization HARQ processes of the uplink subframes as possible before and after the change of the TDD uplink/downlink configuration.
