    摘要: 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.

    摘要: Methods and apparatus for adaptively adjusting temporal parameters such as e.g., wake-up times of digital tracking algorithms (such as timing, frequency and power control). In one exemplary embodiment, wake-up times for tracking loops are based on success/error metrics (e.g., Block Error Rate (BLER), Bit Error Rate (BER), Packet Error Rate (PER), Cyclic Redundancy Checks (CRC), etc.) of one or more previous discontinuous reception (DRX) cycles. In a second embodiment, wake-up times for tracking loops are based on residual frequency and timing errors, etc.

    摘要: Outer loop link adaptation for device resumption. A user equipment (UE) and base station (BS) may be in communication in a first network (e.g., an LTE network). Communication between the UE and the BS may be interrupted, e.g., due to a long fading environment, the UE tuning away to a second network (e.g., a CDMA network). Accordingly, the measured error rate may increase dramatically. After resumption from the interruption, a negative offset may be applied to a reported SINR value from the UE due to the previous increase in error rate. Upon improvement in the error rate, a larger, positive offset adjustment may be added to the negative offset, allowing the estimated SINR to return to reported SINR more quickly. Additionally, the error rate estimation may be adjusted to converge to a more recently measured more quickly by decreasing a feedback filter coefficient.

    摘要: Various method and apparatus embodiments for adjusting control loop parameters for wireless communication link are disclosed. The adjustments may be performed responsive to a single radio UE tuning away from a first network to a second network, or due to a fading condition. Responsive to detecting the tuning away of the UE or the fading condition, the base station may adjust one or more parameters of a control loop. The adjustments may include changing parameters of one or more filters in the BS. For example, a block error rate (BLER) first state can be reset to a small value, or can be incrementally adjusted responsive to detecting discrete transmissions (DTX) or other signals from the UE. In another example, BLER filter coefficients may be updated responsive to DTX detections.

    摘要: 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.
