Embodiment Construction

[0049] 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.

[0050] The existing network usually only determines the cells for capacity expansion and CA function based on the traffic of the cells. This method is based on a single judgment standard and cannot make full use of the efficiency of CA resources. In order to solve this problem, an embodiment of the present invention provides a scheduling method for cell carrier aggregation, the process is as follows figure 1 As shown, the method may includ...

Abstract

The invention, which relates to the technical field of communication, discloses a scheduling method and apparatus for cell carrier aggregation. The method comprises: a plurality of carrier aggregation (CA) scheduling index data of all cells are determined, wherein the CA scheduling index data at least include cell flow ratios that are ratio values of flows of sectors where the cells are located to an average flow value of sectors of the whole network; for each cell, normalization processing is carried out on the CA scheduling index data of the cell and weighted calculation is carried out on the CA scheduling index data after normalization processing to obtain an integrated score of the cell; and CA functions of the cells with the integrated scores larger than a set threshold value are started. Therefore, a problem that the cells for CA function starting are determined only based on flows and thus resources can not be distributed to all cells with large CA needs in priority can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a scheduling method and device for cell carrier aggregation. Background technique [0002] With the continuous evolution of the LTE network, in order to meet the requirements of single-user peak rate and system capacity improvement, one of the most direct methods is to increase system transmission. For this reason, the 3GPP standard proposes carrier aggregation technology bandwidth. Therefore, the LTE-Advanced system introduces a technology for increasing transmission bandwidth, that is, CA (Carrier Aggregation, carrier aggregation). [0003] Thanks to the wider spectrum, the most intuitive benefit after carrier aggregation is the substantial increase in transmission speed and the reduction in latency. At the same time, carrier aggregation can effectively improve network quality, increase throughput, and make network load more balanced, especially when the load is heavy. Simp...
