    Abstract: Methods and apparatus for managing radio measurements during discontinuous reception. In one exemplary embodiment, the distribution of Long Term Evolution (LTE) DRX measurements is staggered or distributed across multiple DRX cycles (which may be contiguous or non-contiguous) so as to reduce the transceiver activity and power consumption. The exemplary UE in one implementation only performs a subset of measurements during each DRX cycle. By staggering or distributing cell measurements over multiple DRX cycles, the UE can improve power consumption, while still conforming to measurement requirements.

    Abstract: Adaptive generation of channel quality indicators based on a current communication scenario. A plurality of sets of channel quality indicator information may be stored for each of a plurality of UE communication scenarios.

    Abstract: A method for reducing power consumption by a wireless communication device is disclosed. The method can include the wireless communication device performing a first measurement of an alternative cell during a first measurement gap; sending a first measurement report generated based on the first measurement to the serving cell; storing the first measurement report; determining a mobility state of the wireless communication device; comparing the mobility state to a mobility threshold criterion; resending the first measurement report to the serving network as a report for a second measurement gap in an instance in which the mobility state satisfies the mobility criterion; and performing a second measurement of the alternative cell during the second measurement gap and sending a second measurement report generated based on the second measurement to the serving cell in an instance in which the mobility state does not satisfy the mobility threshold criterion.

    Abstract: Connected-mode discontinuous reception (C-DRX) cycle scaling by a wireless user equipment (UE) device. The UE may establish a connection with a network via a wireless link, which may operate according to LTE. The UE may communicate with the network via the wireless link using C-DRX over a plurality of C-DRX cycles. Each C-DRX cycle may include a period of time during which the UE operates in a reduced-power state and a scheduled on-duration period of time. An indication may be received to remain in the reduced-power state during the scheduled on-duration period of time of at least one C-DRX cycle. The UE may remain in the reduced-power state during the scheduled on-duration period of time of at least one C-DRX cycle in response to the indication.

    Abstract: Methods, apparatuses and computer readable media are described that adjust signaling messages that include channel quality metrics communicated between a mobile wireless device and a wireless access network before and/or after interruption of a connection to improve downlink performance after resumption of the connection. One or more adjusted channel quality metrics are determined and communicated to the wireless access network to compensate at least in part for an estimate of communication channel performance degradation by a network element of the wireless access network following the interruption and resumption of the connection between the mobile wireless device and the wireless access network.
