Abstract: A method and an apparatus are provided for determining a configuration for a radio frame. A transition from a period of inactivity to a period of activity is detected in a configured discontinuous reception (DRX) cycle. A category of at least one subframe of the radio frame that is likely to be encountered during the period of activity is determined, if a dynamic reconfiguration of time division duplex (TDD) uplink (UL)-downlink (DL) configurations is enabled. The category of the least one subframe includes one of a flexible subframe and a fixed subframe.
