Abstract: A method for reducing power consumption in connected mode discontinuous reception is disclosed. The method can include a wireless communication device sending a transmission for a pending HARQ retransmission process and receiving an ACK for the transmission. The method can further include the wireless communication device determining a subset of remaining uplink transmission opportunities in the pending HARQ retransmission process to monitor for an uplink grant in response to receiving the ACK and monitoring the subset of remaining uplink transmission opportunities for an uplink grant. The method can additionally include the wireless communication device entering a sleep state for any uplink transmission opportunities remaining in the pending HARQ retransmission process after monitoring the subset of remaining uplink transmission opportunities in an instance in which an uplink grant for the pending HARQ retransmission process is not received for any of the subset of remaining uplink transmission opportunities.

Abstract: Performing cell re-selection by a device. A first cell on which to camp may be selected. The device may camp on the first cell in an idle-mode. The device may be configured to perform searches for neighboring cells according to an idle-mode timeline while camping on the first cell. The device may transmit a connection request to the first cell in order to transition the device from the idle-mode to a connected-mode via the first cell. One or more searches for neighboring cells may be performed according to a connected-mode timeline after transmitting the connection request, in response to transmitting the connection request. The one or more searches may be performed before the device establishes the connected-mode with the first cell.

Abstract: Providing adaptive channel state feedback (CSF) reports in discontinuous reception (DRX) scenarios in a power-efficient manner. The described algorithm may be able to make adaptive decisions to carry over the CSF from previous DRX cycles based on channel conditions, DRX cycle length, and/or the requirements of CSF reporting for current DRX cycle. The proposed approach can allow for more efficient power consumption related to CSF reports in DRX scenarios where new CSF reports have little or no impact to throughput.

Abstract: Methods and apparatus for network-based detection and mitigation of hybrid client device reception outage events. For example, in one embodiment, a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1X network and packet-switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA 1X activity, and vice versa. During these tuned-away periods, the network adjusts operation to mitigate adverse effects (e.g., underutilization of radio resources, synchronization loss, etc.).
