Abstract

The embodiment of the invention discloses a method and device for transmitting information between base stations. The method and device are used for solving the problem that in the prior art, interaction of all the information cannot be conducted in time between all the base stations. The method comprises the steps that the first base station selects a first signaling connection which meets the transmission requirement of the first information needing interaction from at least two established signaling connections with different transmission characteristics, and sends the first information to the second base station through the first signaling connection; interaction of the second information related to the first information is conducted between the first base station and the second base station through a second signaling connection different from the first signaling connection. According to the method and device for transmitting the information between the base stations, since interaction of the information and information related to the information can be conducted between the first base station and the second base station through different signaling connections, the efficiency of information interaction between the base stations is improved, and the transmission characteristics of information interaction between the base stations are also improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for transmitting information between base stations. Background technique [0002] Coordinated Multipoint Transmission / Reception (CoMP) technology refers to coordinated transmission between multiple geographically separated transmission points. Generally speaking, the multiple transmission points may be base stations of different cells, or may be multiple remote radio heads (Remote Radio Head, RRH) controlled by the base station of the same cell. Coordinated transmission between multiple transmission points can effectively reduce interference between different transmission points, and improve throughput of user equipment (User Equipment, UE), especially cell edge user equipment. Among them, the downlink multi-point coordinated transmission technology mainly includes: Cooperative Scheduling / Beamforming (CS / CB, Cooperative Scheduling Beamf...
