Abstract: Presented herein are mechanisms to reduce collisions in deployments with Wi-Fi and Shared Access LTE (SAC-LTE) equipment as well SAC-LTE equipment from multiple operators. The mechanisms enhance the baseline energy detection mechanism by incorporating methods to decode cross-technology physical layer elements and media access control (MAC) layer elements in the Wi-Fi system to elements in the SAC-LTE system. The methods described improve the detection potential for transmitters, thereby reducing chances of cross-technology collisions.

Abstract: A method is provided for minimizing cross-technology interference with data transmissions from a wireless device in a shared spectrum. The wireless device obtains data to be wirelessly transmitted in a transmission burst in a first radio access technology (RAT) format over a shared spectrum. The wireless device generates a preamble comprising assistance information related to the transmission burst. The preamble comprises a first preamble portion in the first RAT format and a second preamble portion in a second RAT format. The wireless device transmits the preamble followed by the transmission burst.

Abstract: An emergency caller location system uses enterprise Wireless Local Area Network (WLAN) location systems to provide more accurate location information on an emergency caller. A cellular telephone modifies its WLAN identifier, such as its Media Access Control (MAC) address, in response to a user initiating an emergency call. The MAC address is modified based on an identifier known to the cellular network, such as the phone number, subscriber name, International Mobile Equipment Identifier (IMEI), International Mobile Subscriber Identifier (IMSI), and/or International Circuit Card Identifier (ICCID). The cellular telephone may additionally modify the probe timer of the WLAN interface to enhance the ability of the WLAN location system to determine the location of the device.

Abstract: Techniques are provided for determining, for at least one wireless access point in a wireless network, a number of first-time associations created with one or more wireless client devices in the wireless network. Based upon the determined number of first-time associations created, the number of discovery frames to be sent by the at least one wireless access point may be adjusted.

Abstract: An access point is configured to control peer-to-peer wireless transmission in an area around the access point. The access point receives a message from a service providing device advertising a service. The access point receives another message from a service using device requesting the service. The access point determines whether the service using device or the service is prohibited in the area controlled by the access point. Responsive to a determination that the service using device is prohibited, the access point blocks the service using device from receiving the service. Responsive to a determination that the service is prohibited, the access point blocks the service providing device from providing the service.

Abstract: Modifications to frame/subframe structure are presented herein so that a wirelessdevice can transmit its data within a fraction of a subframe. The device obtains data to be transmitted in an unlicensed spectrum and determines whether an entire subframe is required to completely communicate the data. If the data is small enough to not require the entire subframe, then the device generates a burst transmission to minimize the time period of the subframe used to communicate the data. The device transmits the burst transmission and a parameter indicating the duration of the burst transmission.

Abstract: A fully differential amplifier performs common-mode voltage control while having reduced sensitivity to random offsets and mismatches and improved common-mode control loop bandwidth. The amplifier disclosed comprises an additional common-mode control sub-amplifier, which senses common-mode voltage of the fully differential main amplifier at nodes within the continuous-time signal path feedback network, compares the common-mode voltage sensed with a reference voltage, and regulates depending on the result of the comparison the output common-mode voltage via the existing continuous signal path feedback network. Furthermore the internal common-mode control can be implemented in such a manner as to provide a feed-forward transconductance function in addition to common-mode control if desired. Moreover it is possible to use feedback from other amplifier stages in an amplifier chain to implement common-mode feedback.

Abstract: A capacitance reduction circuit retains a conversion digital code of a previous sampling of an input signal of a delta-sigma modulated ADC and compares a set of least significant data bits and most significant bits of the conversion digital code to a least significant and a most significant boundary codes. When the least significant bits of the conversion digital code are less than or equal to the least significant boundary code or when the most significant bits of the conversion digital code are greater than or equal to the most significant boundary code, the capacitance reduction circuitry generates a capacitance reduction enable/disable code applied to multiple summation-quantization circuits to enable or disable groups of the multiple summation-quantization circuits bits to reduce capacitive loading of the outputs of delta-sigma modulator and an input signal to improve the total harmonic distortion and noise.

Abstract: In an example embodiment, packet encapsulation is employed to facilitate bridging between bridge ports that do not reflect frames (such as 802.1 compatible bridge ports) and bridge ports that do reflect frames (such as 802.11 compatible clients). Packets from a wireless access point may be sent twice, once with a predefined multicast address for processing by 802.11 clients contained in bridges, and once with the original destination address. In particular embodiments, additional means may be employed to minimize the circumstances where packets are duplicated.
