Problems solved by technology

For the far-point terminal located at the edge of the cell, due to the limited spectrum resources of the far-point terminal, if the priority is only adjusted by the instantaneous rate and the long-term average rate, and the wireless resources are allocated accordingly, the data transmission rate of the far-point terminal It is still very low, and the signal quality is poor, so the PF algorithm cannot effectively improve the chances of remote terminals with limited spectrum resources to call resources, and the fairness of remote terminals is still not guaranteed, especially when remote terminals have important services This will seriously affect the experience of far-spot users

Abstract

The invention discloses a wireless resource scheduling method and apparatus, and relates to the technical field of communication. The problems of poor signal quality and poor system fairness of a remote terminal can be solved. The wireless resource scheduling method disclosed by the invention comprises the following steps: determining available carrier information of a terminal, wherein the available information comprises an available carrier number and available carrier frequency; calculating a weight factor according to the available carrier information and a business parameter of current business, wherein the business parameter comprises at least one of a business bearer type, a time delay and a packet loss rate; calculating the corresponding priority of the terminal when transmitting data on each available carrier according to the weight factor, the instant transmission rate of the terminal when transmitting data on each available carrier and the average transmission rate of the terminal when transmitting data on each available carrier; and determining the available carriers with priorities meeting preset requirements as carriers for data transmission. The wireless resource scheduling method and apparatus disclosed by the invention is suitable for application in communication systems with carrier aggregation functions.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for scheduling wireless resources. Background technique [0002] A carrier aggregation (Carrier Aggregation, CA) technology is an important technology in Long Term Evolution Advanced (LTE-Advanced). Carrier aggregation means that user data can be simultaneously transmitted on multiple component carriers (Component Carriers, CCs), which is equivalent to increasing the user's transmission bandwidth. [0003] But at the same time, the carrier aggregation technology also brings many new radio resource management problems to the LTE-Advanced system. Since there are multiple component carriers in the system, and the channel characteristics of each component carrier are different, after a user selects a component carrier, uneven load of the component carriers will occur. Especially in the case of a heavy cell load, this phenomenon is more serious and...
