Abstract
Embodiments of a system and method for providing DRX enhancements in LTE systems are generally described herein. In some embodiments, a system control module is provided for controlling communications via a communications interface. A processor is coupled to the system control module and is 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 for control signals, the processor further monitoring subframes after the active time.
Claims24
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, and
- implement 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.
