摘要： The invention provides methods for implementing synchronous uplink HARQ process in multiple BS coordinated receiving network. According to one embodiment, for synchronous uplink HARQ process with a relatively short response time limit, the service BS provides a receiving response in accordance with the response time limit, and formally instructs the terminal to retransmit or start a new transmission after the merging is completed. According to another embodiment, the synchronous uplink HARQ process has a response time limit matching the delay of multiple BS Coordinated network, and thus the service BS can transmit receiving response or control signaling on PDCCH after the mergence is completed. Thereby, the synchronous uplink HARQ process in multiple BS Coordinated networks of LTE and LTEA can be implemented.
