Definitions

  • FIG. 7 shows a block diagram of a wireless device that supports connected mode extended DRX in accordance with various aspects of the present disclosure
  • UE 115-a may use DRX mode to schedule sleep intervals and conserve energy. In some cases, UE 115-a may use an eDRX mode that implements extended sleep intervals to provide additional energy savings.
  • Wireless communication system 200 may employ configuration techniques to configure and monitor eDRX capable devices for eDRX operation.
  • An eDRX capable device such as UE 115-a may support extended sleep intervals; however, as the scheduled sleep intervals increase (e.g., greater than 10.24 sec) additional control signaling and parameters may be utilized to support the eDRX cycles. Additional control techniques may additionally be implemented to support eDRX operation and maintain compatibility with the network.
  • UE 115-a may use longer DRX ON timers that allow base station's 105-a MAC to re-schedule UE 115-a before UE 115-a enters the sleep state.
  • UE 115-a may report a NACK for a HARQ process and start a timer. If the timer expires before a HARQ retransmission is scheduled the device may request the retransmission. This may trigger a MAC CE transmission including the HARQ retransmission.
  • the UE 115-a may send a scheduling request to a base station 105-a in order to transmit MO data.
  • an extended SR may be utilized that is aligned with eDRX cycles.
  • the eDRX capable device may transition in to connected mode extended DRX. In some cases, the eDRX capable device may transition after determining that the eDRX timer has expired. In other cases, the eDRX capable device may transition after receiving an eDRX command.
  • the receiver 505-a may receive information which may be passed on to connected mode eDRX module 510-a, and to other components of wireless device 600.
  • the connected mode eDRX module 510-a may perform the operations described herein with reference to FIG. 5.
  • the transmitter 515-a may transmit signals received from other components of wireless device 600.
  • the BS hyper SFN module 1105 may transmit an indication of a hyper SFN, where the hyper SFN indicates a time period equal to or greater than the full SFN cycle as described herein with reference to FIGs. 1-4.
  • the base station 105 may configure the wireless device for connected mode extended DRX including a low power period that is longer than a full SFN cycle and an ON duration as described herein with reference to FIGs. 1-4.
  • the operations of block 1810 may be performed by the BS connected mode eDRX configuration module 1010 as described herein with reference to FIG. 10.
  • the base station 105 may maintain the RRC connection with the device during the low power period as described herein with reference to FIGs. 1-4.
  • the operations of block 1815 may be performed by the RRC connection module 605 as described herein with reference to FIG. 6.
  • a general-purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine.
  • a processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).
