Abstract
The present invention relates to a method of a user equipment (UE) using discontinuous reception (DRX) and time division duplex (TDD) carrier aggregation of at least a first and a second cell, the first cell 501 having an UL-DL configuration of uplink (UL) and downlink (DL) subframes 503 which is different from such an UL-DL configuration of the second cell 502. The method comprises setting a first DRX timer 505, the duration of which is dependent on UL-DL configurations of a plurality of aggregated cells, including the first and second cells, such that the duration of the first timer corresponds to a first number of subframes where at least one of the plurality of aggregated cells has a DL subframe. The method also comprises setting a second DRX timer 506, the duration of which is dependent on the UL-DL configuration of a single one of the aggregated cells, such that the duration of the second timer corresponds to a second number of subframes where said single one of the cells has a DL subframe.
