摘要： A method and apparatus to improve the robustness of a wireless communication link between a base station and a mobile communication device. The method increases power selectively on portions of an uplink communication signal transmitted from the mobile communication device to the base station. The method monitors a quality metric value at the mobile communication device and sets the transmit power level of the first portion of an uplink communication signal to the first power level, if the monitored quality metric value is in a first range of quality values, or sets the transmit power level of the first portion of the uplink communication signal to a second power level, if the monitored quality metric value is in a second range of quality values. The first portion of the uplink communication signal includes control signals used by a base station to maintain connection of the wireless communication link.

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： A mobile wireless device adapts receive diversity during discontinuous reception based on downlink signal quality, page indicators and page messages. When the downlink signal quality exceeds a pre-determined threshold, the mobile wireless device decodes a page indicator channel through an initial antenna, and otherwise, decodes a paging channel through the initial antenna without decoding the page indicator channel. The mobile wireless device switches to decoding the paging channel through an alternate antenna when a page indicator decodes as an erasure. When a paging message received through a single antenna decodes with an incorrect error checking code, the mobile wireless devices enables receive diversity through multiple antennas for subsequent decoding. The mobile wireless device switches between single antenna reception and multiple antenna reception based on tracking multiple consecutive error checking code failures and successes.

摘要： Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry with first and second ports that are coupled by switching circuitry to first and second antennas. A first receiver in the transceiver circuitry may be associated with the first port and a second receiver in the transceiver circuitry may be associated with the second port. An electronic device may be operated in a single receiver mode in which only one of the receivers is active to conserve power or a dual receiver mode in which signals from both antennas may be received in parallel to compare antenna performance. Based on antenna performance metrics, the electronic device may adjust the switching circuitry to ensure that an optimal antenna is being used.

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.
