CELL SWITCHING STRATEGY FOR AN LTE-ADVANCED SYSTEM BASED ON CARRIER AGGREGATION TECHNOLOGY

摘要

Various embodiments of a cell switching strategy for an LTE-Advanced system based on the carrier aggregation technology are provided. Compared with the conventional cell switching strategy, the proposed strategy monitors the channel conditions of all the component carriers that are utilized for the communication of a user. The proposed strategy switches cell for one or more of the component carriers with relatively weaker signal strength while maintaining the cell for the other component carriers with better channel quality. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

1. A method, comprising:
monitoring channel conditions of a first component carrier and a second component carrier of a first wireless communication cell that are utilized by a communication device as a primary component carrier and a secondary component carrier, respectively, in carrier aggregation; and releasing one of the first and second component carriers from being utilized by the communication device while maintaining utilization of the other of the first and second component carriers by the communication device in response to a channel condition of the one of the first and second component carriers being less than a channel condition of a corresponding component carrier of a second wireless communication cell.
