Embodiment Construction
[0047] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0048] The basic idea of the present invention is to divide the user equipment of a cell or sector into central user equipment and edge user equipment, and use a resource multiplexing method to make the available system resources of edge users in adjacent cells or sectors orthogonal to each other, so as to Reduce inter-cell interference; at the same time, through the resource reuse method, a section of cooperative system resources is allocated to each cell or sector, and the cooperative frequency band of each cell or sector and the frequency band adjacent to the cell or sector in adjacent cells or sectors The edge area blocks use the same system resources, so that the cooperative transmission technology can be combined to improve the performance of cell edge users.
[0049] Such as figure 1 As shown, it is a schemat...

The invention relates to a resource reuse method for supporting cooperative transmission in a communication system, comprising the following steps: selecting a plurality of mutually adjacent subdistricts or a plurality of mutually adjacent sectors belonging to different subdistricts to form a cluster and dividing each subdistrict or each sector into central zones and marginal zones; dividing available system resources into a central user system resource and a marginal user system resource; dividing the marginal user system resource into a plurality of non-overlapping parts and dividing the marginal zones into a plurality of zone blocks according to the number of adjacent subdistricts or sectors; and selecting different non-overlapping parts as cooperative system resources of the subdistrict or the sector for each subdistrict or each sector, and correspondingly distributing a plurality of non-overlapping parts except the collaboration system resources for a plurality of zone blocks. The invention also relates to a resource reuse system for supporting the cooperative transmission in the communication system. The invention can effectively inhibit interference among the subdistricts, and enhance the marginal use performance of the subdistricts.
Description
technical field [0001] The present invention relates to the communication field, in particular to a resource multiplexing method and system supporting cooperative transmission in a communication system. Background technique [0002] With the development and standardization of the next-generation wireless communication system in full swing and the higher demand for high-speed, high-quality wireless communication services, how to effectively suppress the inter-cell interference in the next-generation wireless communication system has become an issue. Problems to be solved. [0003] 3GPP LTE (Long Term Evolution, Long Term Evolution) system, as a 3G enhanced system evolving from 3G system to 4G system, puts forward a number of evaluation objectives and performance requirements, among which the very important points are: to increase the data rate at the edge of the cell; Significantly improve spectral efficiency. The LTE-Advanced system, which is further evolved from LTE, puts...
