First Claim
1. A mobile communication method for a mobile station device that is configured to and/or programmed to communicate with a base station device, the mobile communication method comprising:
- performing autonomous detection of necessity of monitoring a neighboring cell;
notifying the base station device of a result of the autonomous detection;
receiving, from the base station device, a control signal for permitting the mobile station device to generate a gap for the monitoring, whereinthe gap having one length of plural lengths,each of the plural lengths being based on measurement types, andthe one length being associated with a measurement type of the neighboring cell;
generating the gap based on the control signal, whereincommunication between the mobile station device and the base station device is suspended in the gap, andthe mobile station device, based on the measurement type of the neighboring cell, autonomously decides the one length from among the plural lengths,the plural lengths being previously set, andthe plural lengths being common between the mobile station device and the base station device;
setting a plurality of channel quality indication values to measurement report based on a predetermined pattern, the plurality of channel quality indication values being measured for respective blocks into which a radio frequency band is divided in a predetermined range; and
transmitting, to the base station device, the measurement report of the neighboring cell, whereinthe measurement report being based on measurement in the gap having the length autonomously decided by the mobile station device.

Abstract
A mobile station device includes, but is not limited to: a generation unit. The generation unit generates a gap for suspending communication between the mobile station device and a base station device located in a serving cell and for monitoring a neighboring cell. A predetermined interval based on a measurement type is previously set for a gap. The predetermined interval is common between the mobile station device and the base station device. The mobile station device autonomously detects necessity of generation of the gap for monitoring a neighboring cell, and notifies the base station device of a result of the autonomous detection.
