Abstract

The application, which relates to the communication field, discloses a carrier-aggregation-based resource allocation method and a network communication system. With the resource allocation method and the network communication system, the queuing waiting time for a real-time service can be shortened. The method comprises: queuing waiting time and data packet transmission time of a buffer queue corresponding to each terminal at a designated carrier are obtained; an initial weight is set for each terminal and iteration is carried out on the queuing waiting time, the data packet transmission time and an initial weight to obtain a current weight of each terminal at a current time; a channel quality parameter of each terminal at the current time is obtained, and an instantaneous rate for to-be-transmitted data packet transmission by each terminal at the designate carrier is determined according to the channel quality parameter; on the basis of the current weight, the instantaneous rates, and an average rate of all data packet transmission by each terminal at the designate carrier by the end of the current time, a terminal priority of each terminal at the current time is determined; and resources at the designated carrier at the current time are distributed to the terminal corresponding to the highest priority among the terminal priorities.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a carrier aggregation-based resource allocation method and a network communication system. Background technique [0002] The carrier aggregation technology (English: Carrier Aggregation, referred to as: CA) can aggregate 2 to 5 Long Term Evolution (English: Long Term Evolution, referred to as: LTE) component carriers (English: Component Carrier, referred to as: CC) together to increase Transmission bandwidth, improve uplink and downlink transmission rate. In the carrier aggregation scenario, the component carriers aggregated by the same base station have different frequencies, and carrier signals of different frequencies attenuate differently when they reach the same location. Since the frequency and attenuation of each component carrier will affect the coverage of the component carrier, the coverage of different component carriers is generally differe...
