Embodiment Construction

[0043] The present invention will be described below with reference to the accompanying drawings and embodiments.

[0044] When the macro station interferes with the macro station, and when the macro station interferes with the pico station, the spatial isolation of the two TDD systems is difficult to meet the requirements, which greatly reduces the performance of the system. Moreover, before interference is eliminated or avoided, an interference detection method is urgently needed to locate or narrow down the position of the interference source and the mutual interference relationship, and there is currently no relevant solution for the cross-slot problem in the industry.

[0045] Based on this, an embodiment of the present invention provides an inter-station beam cooperative control method, such as figure 1 As shown, the method is applied to the victim station, including:

[0046] Step 100: Exchange the CSI-RS configuration information with the neighboring cell base station...

Abstract

The embodiment of the invention provides an inter-station beam cooperative control method and device and a computer readable storage medium, and the method comprises the steps: carrying out the interaction of channel state information reference signal (CSI-RS) configuration information with an adjacent cell base station through an Xn interface, or an S1 interface, or an NG interface, or a relay, or an air interface, and enabling a network management side or a base station side to establish a CSI-RS beam mapping relation; the disturbed station judges whether the uplink of the disturbed station is interfered or not based on the adjacent cell wave beam received by the uplink; when it is determined that interference is received, determining an interference applying station corresponding to the interference based on the CSI-RS beam mapping relation; and sending an interference indication to the interference applying station for the interference applying station to adjust the beam power and / or the beam direction.

Description

technical field [0001] The present invention relates to the field of mobile communication technologies, and in particular, to a method, an apparatus and a computer-readable storage medium for beam cooperative control between stations. Background technique [0002] When two TDD systems use the same or adjacent frequencies, if the time slots are not synchronized, cross-slot interference will occur. For example, the 4.9GHz NR public network uses 7D3U, the industry network uses 1D3U, and / or SUL and stock 4G scenarios. When the macro station interferes with the macro station, and when the macro station interferes with the pico station, the spatial isolation of the two TDD systems is difficult to meet the requirements, which greatly reduces the performance of the system. Before interference cancellation or avoidance, interference detection methods are urgently needed to locate or narrow down the location of the interference source and the mutual interference relationship.
