Method and equipment for scheduling radio resource

Abstract

The embodiment of the invention discloses a method and equipment for scheduling radio resource, belonging to the technical field of communication. The method can comprise the following steps: a small base station provides interference related information including position information of the small base station to resource scheduling equipment; the small base station obtains radio resource information distributed by the resource scheduling equipment; the radio resource is distributed to the small base station by the resource scheduling equipment on the basis of the interference related information; and the small base station provides service to the user equipment by using the radio resource. By means of the technical scheme disclosed by the invention, interferences between small base stations or between the small base station and a macro base station can be reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a radio resource scheduling method and device. Background technique [0002] Heterogeneous networks based on traditional cellular networks usually include macro base stations and small base stations. Taking LTE (Long Term Evolution, long-term evolution) network as an example, under the coverage of Macro (macro) eNB (eNodeB, evolved base station, referred to as base station) Various small base stations can be placed, such as Pico (a type of small base station), HeNB (Home eNB, home base station), Femto (a type of small base station) and other wireless access points. These small base stations can access wireless communication networks or Internet (Internet) networks through wired (such as optical fiber), and the wired network has a large access capacity and is not affected by the lack of wireless resources. Therefore, these small base stations have high throughput...

Problems solved by technology

However, if the link quality of UE2 of HeNB A deteriorates, HeNB A will increase its transmit power, resulting in an increase in the coverage of HeNB A, which may affect the channel quality of its neighboring HeNB B. For HeNBs using the same frequency resource f1 B's UE generates interference

On the other hand, although HeNB is less mobile than UE, there will be relocation phenomenon. If HeNB moves to the vicinity of HeNB B, the two wireless links will interfere with each other because they use the same wireless resource f1
