Patent ID: 8660559

Claim:
A terminal apparatus used in a wireless communication system, in which said terminal apparatus and a base station apparatus are communicable with each other using a first serving frequency and a second serving frequency, the terminal apparatus comprising: an event detecting section that detects occurrence of an event that triggers transmission of a measurement report of a radio condition of a first cell at the first serving frequency to the base station apparatus; and a measurement report creating section that creates the measurement report on the basis of the occurrence of the event, the measurement report including information indicating radio conditions of the first cell at the first serving frequency at which the event occurred and of a second cell at the second serving frequency that is different from the first serving frequency, the first serving frequency and the second serving frequency being simultaneously used in the communication between said terminal apparatus and the base station apparatus, the measurement report being for use by the base station apparatus in controlling handover of the terminal apparatus, wherein the measurement report further includes information regarding the best non-serving cell at the second serving frequency, which is selected amongst a plurality of non-serving cells at the second serving frequency based on radio conditions indicated by the received power of the radio waves (RSRP), said plurality of non-serving cells being not presently used in the communication between said terminal apparatus and the base station apparatus.
