Embodiment 1

[0085] The application scenario of embodiment 1 is as follows Figure 4 As shown; assuming that base station A and base station B are currently working in the multi-base station cooperative interference collision avoidance mode, terminal A accesses the cell where base station A is located, and terminal B accesses the cell where base station B is located. Terminal A and terminal B are in multi-base station cooperation mode, and H AA is the channel response from base station A to terminal A, H AB is the channel response from base station A to terminal B, H BA is the channel response from base station B to terminal A, H BB is the channel response from base station B to terminal B. Assume that terminal A is currently transmitting a retransmission data packet.

[0086] Under the restriction of partial channel information sharing, base station A can obtain H AA and H AB , base station B can obtain H BA and H BB . As for how the base station A and the base station B obtain t...

Abstract

The invention discloses a data transmission method and a base station in a multi-base station coordinated system, comprising that: when performing user scheduling for a plurality of times, with respect to the terminal of a current transmission retransmission data package in the district, the base station selects the channel information which has large response relativity with the local district terminal channel, small response relativity with the adjacent district terminal channel, and causes the terminal to obtain highest scheduling priority as the channel information corresponding to the terminal; then the base station selects the terminal with the highest scheduling priority to perform data transmission according to the channel information of each terminal in the local district. In the invention, each base station independently performs user scheduling, and realizes partial avoiding of multi-base station interference through updating the channel information.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and a base station in a multi-base station cooperative system. Background technique [0002] In existing communication systems, such as HSPA (High Speed ​​Packet Access, High Speed ​​Packet Access), 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) LTE (Long Term Evolution, Long Term Evolution), each base station independently Multi-user scheduling. With the development of communication technology, in the next generation of mobile communication systems, such as 3GPP LTE-Advanced (3GPP LTE further evolution) system, the average throughput and peak rate of the system will be greatly increased on the basis of the existing rate by 2-3 times. In order to achieve such a goal, the method of cooperation between multiple cells (multiple base stations) is a very effective method. Because the 3GPP LTE / LTE-Advanced system is an int...
