Problems solved by technology

[0015] However, in the above technical solution, no detailed resource allocation method is designed according to the specific system load of each cell. If adjacent cells with different load conditions adopt the same resource allocation method and ratio, the utilization of limited physical resources will not Not properly arranged, the throughput of the system is also limited
[0016] In addition, the above technical solution does not give a specific relationship between physical resource blocks, coding blocks, and resource blocks for interference detection and elimination. If it is assumed that coding blocks with the same size as the Chunk are mapped for coding, then only Perform "double-user detection" or "multi-user detection" on chunks of the same size to r

Embodiment Construction

[0076] The present invention is realized on the basis of two implementation schemes for avoiding interference based on interference coordination and interference elimination. In the process of realization, dynamic adjustment of frequency resources occupied by interference coordination and interference elimination is realized, so as to effectively support different system environments and various business requirements.

[0077] In the scheme of combining interference coordination and interference elimination provided by the present invention, different frequency resource allocation methods can be used to realize dynamic adjustment of the frequency resources occupied by interference coordination and interference elimination; corresponding frequency resources can be allocated in advance, or Allocation of frequency resources occupied by interference elimination and interference coordination can be completed when the service load changes and meets predetermined conditions.

Abstract

The related method preventing subzone interference comprises: allocating corresponding frequency resource for subzone edge users applying interference coordination and interference elimination respectively, exactly, the frequency resource can be allocated in advance, or allocated when system business loading changes and satisfies a certain condition; then, adjusting the frequency resource for eliminating and coordinating interference. This invention makes full of two ways for avoiding interference, adds system flexibility, and supports wide business request.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a technology for eliminating inter-cell interference. Background technique [0002] At present, multi-carrier-based OFDM (Orthogonal Frequency Division Multiplexing) technology in wireless communication systems has attracted more and more attention from the industry. The basic idea of ​​OFDM technology is to divide the time-frequency resources of the wireless communication system into several orthogonal narrowband sub-channels in the frequency domain, and high-speed data streams are transmitted in parallel on each sub-channel through serial-to-parallel conversion. Due to the narrowband characteristics of the sub-channels, the influence of multipath can be overcome and the orthogonality between the sub-channels can be maintained, thereby ensuring that the interference between users in the cell is very small. [0003] The advantage of the OFDM technology is that it ...
