Abstract

The invention discloses a method for configuring a line loss compensation factor, which comprises the steps that: a base station sets the area division threshold according to the interference signal strength of the strongest interference cell; the base station divides a network covered by the base station into a plurality of layers according to the area division threshold; the base station respectively configures adjustment modes of line loss compensation factor for the divisiory areas. In addition, the invention also discloses a device for configuring the line loss compensation factor. By adopting the technical scheme, the system overload can be effectively reduced, the time of uplink power control can be shortened and the effectiveness of the uplink power control can be improved.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for configuring path loss compensation factors. Background technique [0002] In the next-generation broadband wireless communication network, solving inter-cell interference in the wireless communication network has become a key factor to improve the throughput of user terminals (UT) and the average UT throughput between cells, but at the same time, it is also facing severe challenges. challenge. [0003] At present, the Institute for Electrical and Electronic Engineers (IEEE) 802.16j, International Mobile Telecommunications Advanced (IMT-Advanced), and WINNER all propose methods such as interference randomization, interference coordination, and interference cancellation to solve the problem. The problem of inter-cell interference. In Long-Term Evolution (LTE for short), it is proposed to divide the cell coverage area into inner layer and outer la...
