METHOD AND APPARATUS FOR IMPLEMENTING UPLINK TRANSMISSION IN FLEXIBLE FREQUENCY DIVISION DUPLEX SYSTEM

摘要

A method for implementing uplink transmission in a flexible frequency division duplex (FDD) system is provided. A flexible FDD supported user equipment (FFUE) receives signaling from an evolved node B (eNB), obtains an uplink carrier configuration, and performs physical uplink shared channel (PUSCH) transmission by way of synchronous HARQ of 8 ms, synchronous HARQ of 10 ms, or asynchronous hybrid automatic repeat request (HARQ). According to the solution provided by the present invention, uplink transmission in the FDD system can be realized with low complexity, and the system performance of the FDD system is improved.
