Title:
COMMUNICATION TERMINAL
Document Type and Number:
WIPO Patent Application WO/2010/150462
Kind Code:
A1
Abstract:
Provided is a communication terminal capable of simultaneous communication over a plurality of carriers by means of carrier aggregation, that is equipped with a quality measuring unit that obtains a measured value by measuring the reception quality of radio waves transmitted from the base station of a connected cell over a plurality of carriers, a designated carrier storing unit that stores information specifying a designated carrier selected from among the plurality of carriers, a comparing unit that compares a threshold value with the measured value of the designated carrier measured by the quality measuring unit, and a cell searching unit that searches for an alternate cell when the measured value of the designated carrier is equal to or below the threshold value. As a result, the search threshold corresponding to carrier aggregation can be appropriately determined and cell search and quality measurement can be performed.
