Abstract

The invention provides a method for clustering districts which comprises the following steps of: dividing each district into a district marginal area and an inner area according to a wireless position of the district and organizing a plurality of adjacent district marginal areas into a virtual district. The invention also provides a wireless resource scheduling method based on the method for clustering districts, a movement management method, a district pilot frequency design method, a communication network and a resource scheduling system.

Description

technical field

[0001] The invention relates to wireless resource scheduling, in particular to a multi-cell clustering method, a communication network and a resource scheduling system. Background technique

[0002] Next-generation cellular systems such as 802.16m and LTE-advanced will employ orthogonal multiple access techniques such as OFDMA or SC-FDMA to support high data rate transmissions. In these orthogonal systems, inter-cell co-channel interference is the main factor limiting the performance of the cell edge.

[0003] Relevant specifications have proposed to adopt fractional frequency reuse (FFR) technology and its variants in the LTE R8 system to eliminate inter-cell interference. At present, 802.16m and LTE-advanced are both evolving to IMT-advance, so they both need to meet the performance index requirements proposed by IMT-advanced. However, 3GPP's research on LTE proves that static or semi-static FFR is not enough to provide what IMT-advanced requires. 2 to 3 ...
