    Abstract: It is possible to match the impedance of an antenna without directly measuring the phase. This is advantageous as it reduces the cost, and complexity, of wireless transceivers. In particular, the phase component of an antenna's reflection coefficient can be estimated based on return loss measurements. For example, a transceiver may measure an initial return loss of the antenna, adjust the impedance of at least one tunable element, and then measure one or more adjusted return losses of the antenna. The phase of the reflection coefficient can be estimated based on a difference between the initial return loss and the one or more adjusted return losses.

    Abstract: An apparatus for satisfying Specific Absorption Rate (SAR) compliance criteria including a first capacitance sensor, a second capacitance sensor, a memory, and a processor. The memory is configured to store pre-established proximity regions that include a free space region of proximity based on baseline capacitance measurements obtained from the sensors when no human body is proximate a wireless device and a first region of proximity based on initial capacitance measurements obtained from the sensors when the human body is spaced apart from the wireless device by a first predetermined separation distance. The processor is configured to instruct a radio frequency (RF) transmitter to operate at a first output power when subsequent capacitance measurements received from the sensors are within the free space region of proximity and at a second output power, less than the first output power when the subsequent capacitance measurements are within the first region of proximity.

    Abstract: Embodiments are provided for resolving, at a user equipment (UE), unnecessary frequent consecutive back and forth reselections between the same two or more network cells. In an embodiment method, upon detecting predefined criteria indicating reaching a threshold frequency of reselections between the same cells, the UE switches to a defined mobility state reducing the frequency of reselections between the same cells. In accordance with the defined mobility state, the method increases a waiting time for cell reselection. The predefined criteria includes detecting the UE in a defined Static-idle state, detecting a serving cell of the UE and a strongest neighbor cell having approximately equal signal quality for a defined duration or a defined number of consecutive measurements, and detecting a number of consecutive reselections between the same cells exceeding a defined minimum threshold.

    Abstract: Various disclosed embodiments include methods and systems for operating a wireless electronic device having one or more antennas. The method comprises monitoring at least one parameter of a signal received from a remote transmitter. The method includes determining that the at least one parameter meets a first threshold and performing, at the wireless electronic device, a probing operation. The probing operation includes performing an antenna switching operation. The probing operation includes generating first signal information of the received signal prior to the antenna switching operation and generating second signal information of the received signal subsequent to the antenna switching operation. The probing operation includes determining whether the antenna switching operation achieves a desired gain based at least in part on the generated first and second signal information. The probing operation includes reversing the antenna switching operation in response to the desired gain not being achieved.
