Claim:
1. A method for transmitting hybrid automatic repeat request (HARQ) for uplink data in support of multi-subframe scheduling in a user equipment (UE), the method comprising: receiving, from a base station, information on a physical HARQ indicator channel (PHICH) and a multi-subframe scheduling uplink grant signaling, respectively; determining timing positions of a scheduled uplink subframe and a subsequent physical uplink shared control channel (PUSCH) transmission of a synchronous HARQ (SHARQ) process of the scheduled uplink subframe, according to a timing relationship between the multi-subframe scheduling uplink grant signaling and the scheduled uplink subframe; and for the scheduled uplink subframe, determining parameters of a subsequent uplink transmission according to the multi-subframe uplink grant signaling which schedules the SHARQ process of the scheduled uplink subframe and a relative transmission position of the PHICH, and performing data transmission or stopping a current transmission in the scheduled uplink subframe according to the parameters, wherein the timing positions are determined based on a time-division duplexing (TDD) uplink-downlink (UL-DL) configuration transmitted in a system information block or a reference UL-DL configuration by high-layer signaling.
