Abstract: Methodologies and apparatus to support interworking operations between a cellular radio area network (RAN) and a wireless local area network (WLAN) utilizing broadcast RAN assistance information. In various embodiments, a RAN (such as a LTE/LTE-advanced RAN) transmits RAN assistance information to a multimode user equipment (UE) for use in network selection and traffic steering operations. Certain parameters, such as RAN load assistance information, may be transmitted in a first format or a second, less granular format that changes relatively infrequently over time as compared to the first format. A system information broadcast procedure utilizing a paging message is employed to transmit information in the second format. The paging message may include a change notification flag that triggers a UE to initiate a system information acquisition procedure to a retrieve system information message(s) including the relevant interworking parameters.

Abstract: Systems and methods are provided for encrypting a data transmission from a base station at the physical layer, such that the data transmission can only be decoded successfully by an intended UE. In an embodiment, a desired signal component, including a data signal for an intended UE, is combined with an interference component to generate a signal for transmission. The interference component is designed such that it falls in a null space of the channel from the base station to the intended UE and is therefore not received by the intended UE. In contrast, for an unintended UE, the interference component is designed to interfere with the desired signal component at the unintended UE, preventing the unintended UE from successfully decoding the data transmission.

Abstract: A high speed level shifter interfaces a high speed DAC to the digital information that the DAC processes. The level shifter may convert CMOS level digital representations to, for example, CML level digital representations for processing by the DAC. The level shifter conserves the voltage swing in the CMOS level representations (e.g., about 1V). The level shifter also avoids voltage overstress, using a feedback loop to constrain the voltage amplitude, and thereby facilitates the use of fast thin film transistors in its architecture.

Abstract: Embodiments of a hysteretic switching regulator with reduced switching frequency variation over changes in one or more of input voltage, output voltage, and temperature are provided herein. A frequency adjust controller is specifically used to adjust a parameter of an integrator within the hysteretic switching regulator to compensate for changes in one or more of input voltage, output voltage, and temperature to maintain the switching frequency of the regulator within a narrow frequency range. Limiting the potentially wide switching frequency variation makes filtering of electromagnetic interference (EMI) caused by the switching action of the hysteretic switching regulator more effective and simpler to implement.

Abstract: Each entry in a prioritized measurement list defines a unique combination of frequency layer and radio access technology (RAT) for cells. Based on signal strength and/or signal quality of the serving cell, a set of entries for measuring is selected from a neighbor list according to the prioritized measurement list and according to a selection rule. The selection rule provides: for the case the at least signal strength or quality of the serving cell is higher than a respective strength/quality threshold, the selected set is a first set; and for the case the at least signal strength or quality of the serving cell is lower than a respective strength/quality threshold, the selected set is a different second set of the prioritized measurement list that excludes all frequency layers of the prioritized measurement list belonging to the RAT having a highest (or alternatively a lowest) priority.

A communications receiver may carry out an offset adjustment algorithm to compensate for the one or more offsets. An initial search procedure determines one or more signal metric maps for one or more selected offset adjustment corrections from the one or more offset adjustment corrections. The offset adjustment algorithm determines one or more optimal points for one or more selected offset adjustment correction based upon the one or more signal maps. The adaptive offset algorithm adjusts each of the one or more selected offset adjustment corrections to their respective optimal points and/or each of one or more non-selected offset adjustment corrections to a corresponding one of a plurality of possible offset corrections to provide one or more adjusted offset adjustment corrections. A tracking mode procedure optimizes the one or more adjusted offset adjustment corrections.
