Embodiment Construction

[0034] Basic thought of the present invention is:

[0035] First, set a component carrier that provides coverage performance for each sector through the carrier management mechanism, and make the frequency of component carriers that provide coverage in adjacent sectors different;

[0036] According to the fact that users at the edge of a sector usually have poor channel conditions and are not suitable for aggregating multiple carriers for data transmission, the primary component carrier of the edge user of the sector is limited to the component carrier that provides coverage performance and has no secondary component carrier, so as to avoid Interference between users at the edge of adjacent sectors to achieve the purpose of suppressing co-frequency interference at the edge of the cell;

[0037] According to the fact that the channel conditions of the central user in the sector are generally good and are suitable for aggregating multiple carriers for data transmission, configur...

Abstract

The invention provides a carrier resource planning method under a carrier aggregation scene. The method comprises the following steps: setting a component carrier providing covering performance for each sector, and enabling the component carriers providing covering of adjacent sectors to have different frequencies; setting the main component carrier of edge users of each sector as the component carrier providing edge covering performance of the sector, configuring carrier aggregation for a central user of the sectors, and setting the component carrier providing edge covering as the main component carrier of the central user. The carrier resource planning method under the carrier aggregation scene can restrain same frequency interference among cells under a frequency planning scheme of multiple component carriers.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to carrier aggregation (CA, Carrier Aggregation) technology, and in particular to a carrier aggregation scenario download wave resource planning method. Background technique [0002] Carrier Aggregation (CA, Carrier Aggregation) technology is one of the key technologies proposed by LTE-A relative to LTE evolution, and is a technology for aggregating multiple discontinuous or continuous frequency bands together. Each aggregated frequency band is called a component carrier (CC, Component Carrier). Five CA deployment scenarios are defined in 3GPP TS 36.300, such as Figure 1a to Figure 1e shown. [0003] Figure 1a In the deployment scenario shown, frequency bands F1 and F2 provide the same cell coverage. This deployment scenario is generally applied when F1 and F2 are in the same frequency band, such as 2GHz, 800MHz, and so on. CA is supported in areas where F...
