Problems solved by technology

[0003] Considering that the coverage of different sectors of the F-band cell and the D-band cell in the actual network may be inconsistent, the F-band cell and the D-band cell cannot overlap and cover as expected, especially when the traffic is busy. The problem with the existing technical solution is , using a fixed secondary carrier may reduce resource utilization, which will greatly reduce the effect of carrier aggregation

Abstract

The present invention provides a carrier aggregation configuration method and device, wherein the configuration method is applied to a network side, and comprises the steps of determining the information of an accessed cell when a terminal accesses a first frequency band carrier, and setting the accessed cell as a main cell; determining a cell set to which the main cell belongs, wherein the cells in the cell set all have at least part of overlapped coverage of the first frequency band carrier and a second frequency band carrier; obtaining the measurement information for measuring the performance of the second frequency band carrier of each cell in the cell set, ranking the cells in the cell set according to the cell network performance parameters in the measurement information to obtain the cell having the optimal network performance of the second frequency band carrier, and setting the cell as the assistant cell of the terminal; sending the first reconfiguration information to the terminal via a radio resource control (RRC) message, and accessing the assistant cell by the terminal, wherein the first reconfiguration information comprises the information of the assistant cell.

Description

technical field [0001] The present invention relates to the wireless field, in particular to a carrier aggregation configuration method and device. Background technique [0002] The existing CA (Carrier Aggregation, carrier aggregation) technology is used to perform carrier aggregation for CA users by binding two cells fixedly. When Carrier Aggregation is performed in F-band and D-band cells, the F-band coverage is good, and users preferentially reside in the F-band cell. The F-band cell serves as the primary carrier, and the D-band cell serves as the secondary carrier to provide CA users with the carrier aggregation function. [0003] Considering that the coverage of different sectors of the F-band cell and the D-band cell in the actual network may be inconsistent, the F-band cell and the D-band cell cannot overlap and cover as expected, especially when the traffic is busy. The problem with the existing technical solution is , using a fixed secondary carrier may reduce res...
