1. A user equipment, comprising:

  • a system control module arranged to control communications via a communications interface; and

    a processor, coupled to the system control module, the processor arranged to;

    implement an inactivity timer and an on-duration timer for determining an active time for monitoring subframes on the physical downlink control channel (PDCCH) for control signals indicating resource allocations,monitor subframes after the active time, andimplement a continuous reception mode, a short discontinuous reception cycle and a long discontinuous reception cycle, wherein a start offset of the long discontinuous reception cycle is set to seventy milliseconds to allow monitoring during a Hybrid Automatic Repeat Request (HARQ) timing period.
