TELECOMMUNICATIONS APPARATUS AND METHODS FOR PERFORMING MEASUREMENTS OF AN UNLICENSED CARRIER

摘要

A method of operating a terminal device to perform measurement event evaluation for measurement reporting in respect of a downlink carrier operating in a wireless telecommunications system. The method comprises determining that measurement event evaluation for the downlink carrier should be undertaken beginning at a start time. Measurements of a parameter, such as a reference signal received power, associated with radio channel conditions for frequency resources used by the downlink carrier are obtained during an evaluation period beginning at the start time. The extent to which the downlink carrier is being transmitted during the evaluation period is also established. Whether or not to send a measurement report to network infrastructure equipment is then evaluated by taking account of both the measurements of the parameter during the evaluation period and the extent to which the downlink carrier is being transmitted during the evaluation period. A measurement report is sent by the terminal device to the network infrastructure equipment depending on the outcome of the evaluation.

1. A method of operating a terminal device to perform measurement event evaluation for measurement reporting in respect of a downlink carrier operating in a wireless telecommunications system, the method comprising:
determining that measurement event evaluation for the downlink carrier should be undertaken from a start time; obtaining measurements of a parameter associated with radio channel conditions for frequency resources used by the downlink carrier during an evaluation period beginning at the start time; establishing the extent to which the downlink carrier is being transmitted during the evaluation period; and evaluating whether to send a measurement report to network infrastructure equipment by taking account of both the measurements of the parameter during the evaluation period and the extent to which the downlink carrier is being transmitted during the evaluation period.
