  • determining that a length of time for a transmission time interval for communication between a mobile node and a network node is changed; and

    implementing, for a plurality of timers related to discontinuous reception, each of said timers according to one rule of a set of rules that define a time duration of the respective timer while said changed length of time for the transmission time interval is in effect, and the set of rules comprises;

    define a new sub-physical downlink control channel subframe which refers to said changed length of time for the transmission time interval, and count the timer in number of said changed transmission time intervals with a physical downlink control channel;

    define a new sub-subframe with said changed length of time for the transmission time interval and scale the timer to said changed length of time for the transmission time interval; and

    keep the timer duration unchanged regardless of a length of time for the transmission time interval.
