Abstract
Official abstract text for this publication.
The present application relates to of the communication field and discloses a method, device and system for implementing frequency point switch based on CR. The method comprises: determining, by a cognitive base station, a candidate working frequency point for UE deployed in a cognitive frequency band; then sending to the UE broadcast information which at least carries the candidate working frequency point and instructing the UE to switch from the working frequency point currently used thereby to the candidate working frequency point by way of a frequency point switching command. In this way, the UE deployed in the cognitive frequency band can achieve frequency point switch quickly and accurately according to the instruction from the cognitive base station when an incumbent user accesses the working frequency point currently used by the UE, effectively avoiding interference to the incumbent user and thereby ensuring the service performance and service continuity of the system. The present application also discloses a corresponding device and system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for implementing frequency point switch based on Cognitive Radio, CR, comprising: determining, by a cognitive base station, a candidate operating frequency point for a User Equipment, UE, deployed in a cognitive frequency band; and transmitting, by the cognitive base station, broadcast information carrying at least the candidate operating frequency point to the UE and instructing the UE in a frequency point switching command to switch from a…
