Shared method and system of uplink frequency spectrum

Abstract

The invention relates to a shared method and system of an uplink frequency spectrum, aiming at the interference problem of a family base stations / macro-honeycomb base stations mixing network to carry out adaptability soft frequency reuse. In the method, a traditional soft frequency reuse method is adopted to confront the interference problem between macro-honeycomb cells, and the frequency interference problem between the family base stations / macro-honeycomb base stations is allocated and eliminated by using an orthorhombic spectrum. Simultaneously, an effective interference coordination mechanism is further provided for providing a complete solving scheme and facing the interference coordination problem between the family base stations; and facing the optimal utilization of spectrum at auser end, a spectrum scheduling method based on data packets is provided, wherein the service demands of a user in various aspects are comprehensively considered in the spectrum scheduling method forthe purpose of promoting the spectrum efficiency of the system and achieving the maximization of weighing volume of the user.

Description

Uplink Spectrum Sharing Method and System technical field The invention relates to the technical field of wireless communication, in particular to an uplink frequency spectrum sharing method and system in a macrocell / home base station hybrid network environment. Background technique With the continuous development of wireless communication technology, the evolution of standard technology in the telecommunications industry is also accelerating: when 3G networks began to be deployed on a large scale in China, the collection of 4G communication technology was already in full swing. On the one hand, the increasing mobile applications and users' increasing data transmission rate requirements have become the main trend of the mobile communication industry, driving the current network to accelerate to 4G with Orthogonal Frequency Division Multiple Access (OFDMA) as the core technology. Communication technology to support larger capacity data communication; on the other hand, indo...

Problems solved by technology

On the one hand, this solution still has shortcomings. There may still be non-negligible interference between the hotspot coverage in the center of the cell and the macrocell using the same resource; on the other hand, if this solution is directly applied to uplink transmission, due to the needs of cell edge users Increase the transmission power to compensate for the large path loss between the macrocell base station from the edge of the cell to the center of the cell, which may cause greater interference to adjacent femtocells
