Abstract

A joint resource allocation method ensuring a QoS requirement in a collaboration cognitive network belongs to the technical field of wireless communication. In the collaboration cognitive network, a secondary system assists a primary system to reach target effective capacity of a user, and the secondary system uses a leisure sub-carrier to transmit own signal at the same time. The resource allocation algorithm not only performs optimal distribution to power allocation of the secondary system and subcarrier allocation in a joint manner to reach a goal of high energy efficiency, but also considers the QoS (quality of service) requirement of a system. The joint resource allocation method of the invention balances limited radio resource and QoS requirement which is improved constantly so as to fills the blank of performing resource allocation and ensuring the QoS requirement in the collaboration cognitive network.

Description

technical field [0001] The invention relates to a joint resource allocation method for guaranteeing QoS requirements in a cooperative cognitive network, and belongs to the technical field of wireless communication. Background technique [0002] With the increasing number of wireless applications and devices, the serious problem of how to meet the growing demand for radio spectrum has attracted widespread attention. In addition, the Federal Communications Commission (FCC) of the United States has also reported that there is currently a very inefficient use of authorized spectrum. [0003] In wireless communication network transmission, QoS (Quality of Service) plays an important role, and the effective capacity method is an effective technique to study the statistical QoS performance of wireless transmission. How to achieve a balance between limited wireless resources and the ever-increasing QoS requirements of multimedia services is the focus of current wireless communicati...
