Cognitive radio system, resource allocation apparatus thereof and method therefor
First Claim
1. An electronic device in a wireless communication system, comprising:
- processing circuitry configured to;
evaluate an availability of transmission opportunities in wireless resources;
identify a plurality of available transmission opportunities according to a result of the evaluation;
rank the plurality of available transmission opportunities for at least one user terminal; and
transmit rankings of the plurality of available transmission opportunities to the at least one user terminal, so the at least one user terminal can select from the plurality of selection opportunities.

Abstract
Disclosed is a cognitive radio system, resource allocation apparatus thereof and method therefor. A resource allocation apparatus comprises: a transmission opportunity assessment device which is used to assess availabilities of transmission opportunities in radio resources of a primary communication system; a vector production device which is used to set a transmission opportunity selection vector for each secondary user in the cognitive radio system based on assessment results of the availabilities of transmission opportunities, wherein the transmission opportunity selection vector includes information for identifying multiple transmission opportunities assessed available; and a sending device which is used to distribute the transmission opportunity selection vector to the secondary user.

10. An electronic device in a wireless communication system, comprising:
-
processing circuitry configured to; obtain rank information of a plurality of available transmission opportunities for wireless transmission by the electronic device, the rank information comprising wireless transmission priorities of the plurality of available transmission opportunities for the electronic device; and sense at least one of the plurality of available transmission opportunities based on the rank information, to judge whether the at least one of the plurality of available transmission opportunities is currently available, and to determine that the at least one of the plurality of available transmission opportunities is available for wireless transmission if the sensed available transmission opportunity is currently available. - View Dependent Claims (11, 12, 13, 14)
