Methods and devices for implementing synchronous uplink HARQ process in multiple BS coordinated receiving networks

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.

主权项

1. A method, operative in a service base station (BS) of a multiple BS coordinated receiving network, used for implementing a synchronous uplink HARQ process, wherein the service BS completes a signal merging process after a response time limit of said synchronous uplink HARQ process expires, said method comprising:
receiving a first uplink signal sent by a mobile terminal for the synchronous uplink HARQ process; and sending a delaying indication information to the mobile terminal before the response time limit of the synchronous uplink HARQ process expires, the delay information indicating to delay a sending of a follow-up uplink signal for the synchronous uplink HARQ process; wherein said signal merging process includes: receiving at least one forwarded signal forwarded by at least one assistant BS after receiving the first uplink signal; and merging the received first uplink signal with the forwarded signal; and wherein said method further comprises indicating to the mobile terminal to send the follow-up uplink signal for the synchronous uplink HARQ process, based on a result of said merging.
