Abstract
A method for requesting an uplink scheduling is provided. In the case that there is an SR PUCCH resource established on a secondary cell, not an SR PUCCH resource established on a primary cell, and a special secondary cell is in a state of de-activation at the time of sending an uplink scheduling request, the uplink scheduling request is stopped and a random access procedure is initiated. If the uplink scheduling request can be sent on a plurality of cells at the same point of time, that is, if there are a plurality of uplink resources available for the uplink scheduling request at the same point of time, the uplink scheduling request is sent only on one of the plurality of cells (and using only one uplink resource).
