Embodiment Construction

[0071] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0072] Therefore, when a multi-carrier terminal is scheduled on each carrier, the average scheduling rate used in the calculation of the scheduling priority is the rate at the user / bearer level, that is, the average scheduling rate of the multi-carrier terminal on each carrier Sum. The calculation formula of the scheduling priority of the multi-carrier terminal is as follows:

Abstract

The embodiment of the invention discloses a data scheduling method and device. The method comprises the steps of receiving channel quality information transmitted by a first terminal which is a terminal activating multiple carriers, using the channel quality information to calculate the current instantaneous scheduling rate of the first terminal in a first carrier unit, obtaining the average scheduling rate of the first terminal in the first carrier unit, using the instantaneous scheduling rate and the average scheduling rate to calculate the scheduling priority level of the first terminal in the first carrier unit, and distributing physical resources of first carriers to the first terminal according to the order of the the scheduling priority levels of terminals requiring distribution of the physical resources from high to low. The terminals requiring distribution of the physical resources comprise the first terminal and a second terminal. The multiple-carrier terminals are enabled to obtain a stable high rate and the differentiation among the terminals is presented. Moreover, the fairness between the multiple-carrier terminals and non-multiple-carrier terminals are also taken into consideration.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data scheduling method and equipment. Background technique [0002] Due to the limitation of spectrum utilization in the wireless cellular communication system, the bandwidth occupied by each user is limited, so it is increasingly difficult to meet the transmission requirements of high-speed data services. It will become an urgent need to provide users with more reliable high-speed data services in the future wireless broadband mobile network. [0003] In order to improve spectrum utilization, a CA (Carrier Aggregation, carrier aggregation) technology is introduced in LTE-A (Long Term Evolution Advanced, advanced long-term evolution). CA technology utilizes the spectrum resources scattered in multiple frequency bands to obtain larger bandwidth, thereby increasing the peak data rate and system scheduling rate, and also solves the problem of discontinuous spectrum...
