Embodiment Construction

[0042] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0043] Such as figure 1 As shown, an embodiment of the present invention provides a cell configuration method applied to carrier aggregation, including:

[0044] Step 11, acquiring cell sets constituting multiple carrier aggregations covered by continuous signals;

[0045] Step 12, determining the frequency points that exist in each cell set;

[0046] Step 13, taking the cell corresponding to the frequency point in each cell set as the primary cell;

[0047] Step 14, using the remaining cells in each cell set as secondary cells;

[0048] Step 15, merge the primary cells of each cell set into one logical cell.

[0049] The cell configuration method of the present invention combines multiple carrier aggregation primary cells covered by continuous signa...

Abstract

The invention provides a cell configuration method and device applied to carrier aggregation and a network background, and relates to the field of communications. The method comprises the following steps: acquiring a plurality of cell sets of carrier aggregation constructing continuous signal coverage; determining frequency points existing in the cell sets; using cells corresponding to the frequency points in the cell sets as primary cells; using the rest of cells in the cell sets as secondary cells; and combining the primary cells of the cell sets into a logical cell. Through the scheme of the invention, the primary cell switching times of a terminal in a moving process can be reduced, so that a terminal switching failure rate is lowered, and the moving experience of a user is ensured.

Description

technical field [0001] The invention relates to the communication field, in particular to a cell configuration method, device and network background applied to carrier aggregation. Background technique [0002] In order to meet the peak rate requirements, the LTE-A (Long Term Evolution-Advanced) system currently supports a maximum bandwidth of 100MHz. However, it is difficult to find such a large bandwidth in the existing available spectrum resources, and large bandwidth is critical for the hardware design of base stations and terminals. bring great difficulty. In addition, for spectrum resources scattered in multiple frequency bands, a technology is urgently needed to make full use of them. Based on the above considerations, the LTE-A system introduces the key technology of CA (Carrier Aggregation, carrier aggregation). [0003] Carrier aggregation is a function introduced by 3GPP R10. It can meet the larger bandwidth requirements of the LTE-A system and is an essential t...
