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.

摘要： An electronic device may contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. The electronic device may use the multiple antennas to make received signal power measurements. The signal power measurements may be made for each frequency in a list of frequencies used most recently by the electronic device in conveying data traffic between the electronic device and a wireless network. Based on received signal power measurements, the electronic device may select which frequency to use in performing system acquisition operations to attempt to establish a wireless communications link between the electronic device and the wireless network. The device may make signal power measurements for each antenna in the device to determine which antenna should be used in performing the system acquisition operations or may rotate through antennas in sequence to identify an antenna that can successfully perform system acquisition operations.

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.
