Abstract

The present invention provides a communication method, device and base station between base stations, wherein the communication method includes: in the transmission time unit for uplink or downlink data transmission, sending the dedicated air interface signal of the first base station itself in the first time window, and Listening to the first air interface signal sent by the second base station in the second time window; wherein, the first air interface signal includes the second air interface signal detected by the second base station and the dedicated air interface signal of the second base station itself. The embodiments of the present invention solve the problems in the prior art that new interference types are easily generated in a dynamic TDD scenario and downlink channel quality measurement results are outdated or invalid due to the inability to identify the uplink and downlink transmission directions of neighboring cells.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, device and base station between base stations. Background technique [0002] In order to better support dynamic changes in service loads, dynamic time division duplexing (Time Division Duplexing, TDD) technology has been studied in 5G new air interface technology, which supports flexible changes in uplink and downlink transmission directions in TDD spectrum. However, compared with the traditional LTE system, when the transmission directions of adjacent transmission points (Transport Point, TRP) are inconsistent, the dynamic TDD technology may introduce new interference types, wherein the new interference types include interference between TRP and TRP and Interference between a user terminal (User Equipment, UE) and the UE. For example, if figure 1 Shown is a schematic diagram of the interference problem in a dynamic TDD scenario. exist fi...
