Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] As we all know, in the LTE-A communication system, the allocation unit of frequency resources is the physical resource block PRB, that is, each PRB occupies a time slot in the time domain, that is, 0.5ms; and occupies 12 subcarriers in the frequency domain, a total of 180khz .

[0027] The present invention is a resource configuration method of a home base station: a newly-built home base station first predicts the interference generated by it to the local cell and neighboring cells after occupying each PRB, and then comprehensively considers the maximum interference threshold allowed by the local cell and neighboring cells, and screens out And judge whether each PRB is available, and obtain its corresponding transmit power based on the avai...

Abstract

The invention provides a resource configuration method for a family base station. The method is used for restricting the interference of a newly established family base station on an existing family base station and simultaneously ensures the performance of the family base station. In the invention, by predicting the interference on the local district and the adjacent district after the newly established family base station occupies each physical resource block (PRB) and simultaneously and comprehensively considering the allowable maximum interference threshold of the local district and the adjacent district, the suitable physical resource block is selected for the newly established base station, and the corresponding emitting power is dispensed. The resource configuration method has the advantages of ensuring the performance of the newly established family base stations and being compatible with the performance of the adjacent family base station, and effectively controlling the interference between the districts, thus improving system capacity.

Description

technical field [0001] The present invention relates to a resource allocation method of a home base station, to be precise, to a kind of subsequent evolution LTE-A system of cellular mobile communication long-term evolution technology, in which a new home base station occupies different physical resource blocks PRB (Physical Resource Block) Finally, predict and estimate the interference impact between the local cell and neighboring cells, screen PRBs and perform priority sorting and selection, so as not only to ensure the communication performance in the local cell, but also to take into account the adjacent cell communication after the introduction of the new home base station performance. It belongs to the technical field of mobile communication. Background technique [0002] Statistics show that in the future 80-90% of communication system throughput will occur in indoor and hot spots. However, the traditional cellular network technology has the characteristics of "emph...
