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.
摘要翻译：用于设备恢复的外环链路自适应。用户设备（UE）和基站（BS）可以在第一网络（例如，LTE网络）中进行通信。 UE和BS之间的通信可能被中断，例如由于漫长的衰落环境，UE调谐到第二网络（例如，CDMA网络）。因此，测量的误码率可能会急剧增加。在从中断恢复之后，由于错误率的先前增加，可能对来自UE的所报告的SINR值应用负偏移。在改进误差率时，可以将更大的正偏移调整添加到负偏移，从而允许估计的SINR更快地返回到所报告的SINR。此外，可以通过减小反馈滤波器系数来调整误差率估计以收敛到更近的测量更快。

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： A methodology for determining a periodicity of a neighbor cell search for a cellular mobile device is disclosed. The neighbor cell searches may be conducted during discontinuous reception (DRX) paging cycles. However, instead of performing a neighbor cell search during each DRX paging cycle, the period for performing a neighbor cell search may be adaptively determined. Various metrics may be used in determining the periodicity for neighbor cell searches. In various embodiments, two or more metrics may be utilized in combination to determine the neighbor cell search periodicity.

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.
