Abstract: Methods and apparatus for adjusting adaptive control loop behavior based on, for example measured artifacts of the radio environment. In one embodiment, a Long Term Evolution (LTE) user equipment (UE) adjusts one or more Automatic Gain Control (AGC) loops based on a measured Doppler spread of received signals. Specifically, one or more AGC parameters (e.g., set-point, loop gain, etc.) are selected based on a measured Doppler spread. The one or more AGC parameters are configured to optimize both the AGC headroom (e.g., dynamic range) and the signal to quantization plus noise ratio (SQNR) of the receiver under dynamic wireless fading channels for the detected Doppler.

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 IX network and packet- switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA I X 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.).

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. The information may be usable in generating a channel quality indicator. During operation of the UE, a current communication scenario of the UE may be determined. A first set of channel quality indicator information may be selected based on the determined current communication scenario being experienced by the UE. At least one channel quality indicator may be determined based on the selected first set of channel quality indicator information. Finally, the channel quality indicator may be provided to a base station.

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: 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: Methods and apparatus for adaptively adjusting temporal parameters (e.g., neighbor cell search durations). In one embodiment, neighbor cell search durations during discontinuous reception are based on a physical channel metric indicating signal strength and quality (e.g. Reference Signal Received Power (RSRP), Received Signal Strength Indication (RSSI), Reference Signal Receive Quality (RSRQ), etc.) of a cell. In a second embodiment, neighbor cell search durations are based on a multitude of physical layer metrics from one or more cells. In one variant, the multitude of physical layer metrics may include signal strength and quality metrics from the serving base station as well as signal strength and quality indicators from neighbor cells derived from the cells respective synchronization sequences.
