摘要
A method of handling PUSCH data retransmission collision, in a user terminal of TDD, wherein, the user terminal uses a first UL/DL configuration mode in a first radio frame, the method comprises the following steps: receiving a reconfiguration message from a base station, the reconfiguration message is used to indicate the user terminal to use a second UL/DL configuration mode in a second radio frame; judging whether PHICH for a first PUSCH data transmission is located in the first radio frame; if yes, judging whether the second radio frame includes a collision subframe, wherein, the downlink subframe occupied by the PHICH is also used to bear uplink retransmission resource allocation; when including, determining a retransmission uplink subframe used to retransmit PUSCH data by using a remapping scheme, when the second radio frame includes the collision subframe; and retransmitting the PUSCH data in the retransmission uplink subframe.
