A method and device for WLAN power and channel joint configuration

Abstract

A method for joint configuration of power and channel of a WLAN is provided, including: selecting transmitting power of each AP from transmitting power ranges of APs of a WLAN to form an AP transmitting power combination; determining a set of AP operating channel combinations corresponding to each AP transmitting power combination according to operating channels of the APs in the WLAN; calculating an estimated load of each AP corresponding to each AP operating channel combination corresponding to each AP transmitting power combination, and calculating KPIs of the WLAN corresponding to each AP operating channel combination according to the estimated load of each AP; and selecting, according to the calculated KPIs, an optimal channel configuration scheme of the WLAN corresponding to each AP transmitting power combination, and selecting an optimal power and channel configuration scheme of the WLAN, thereby improving throughput and resource utilization efficiency of the WLAN.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and device for jointly configuring power and channels of a WLAN. Background technique [0002] Spectrum planning and power optimization is an important research topic in wireless networks, where the main purpose is to maximize system throughput while taking coverage into account. The current basic method of spectrum planning and power optimization is to allocate more resources (including spectrum (channel) and power) to cells with high service demand, and to avoid excessive interference from areas with low service demand to areas with high service demand. In a WLAN (Wireless Local Access Network, wireless local area network) network, the available orthogonal channels are limited, there may be co-channel interference in adjacent areas, and the unique carrier sense mechanism of WLAN may cause interference in adjacent areas to the target area severely im...

Problems solved by technology

The second existing technology is a power adjustment scheme for a single base station, which does not consider the influence of adjacent areas. The impact of the adjustment method on the performance of the entire network is unpredictable. In addition, the channel adjustment is not considered in the existing technology 2, and power and channel balance cannot be realized. Federation configuration and optimization
