Abstract:
1. A method for Hybrid Automatic Repeat Request (HARQ) process allocation for Downlink (DL) Semi-Persistant (SPS) transmission between a base station and a User Equipment (UE), comprising: at the base station side, configuring a HARQ process preserved for an SPS transmission and related control information for the SPS transmission based on Radio Resource Control (RRC) or control instructions from an upper layer, and transmitting the configured HARQ process and its related control information to the UE; determining a HARQ process allocated to the current transmission, and allocating the HARQ process preserved for the SPS transmission to possible Dynamic Scheduling (DS) transmissions when the SPS transmission is in idle; and determining whether an SPS of DS transmission or retransmission is to be carried in the current HARQ process based on a preset criteria, then performing the determined type of transmission or retransmission, and correspondingly sending a Physical Downlink Control Channel (PDCCH) downlink.
