Abstract: Methods and systems for merging isolated networks. One method includes determining that a second network is located within a predetermined distance of a first network. The method also includes exchanging content between a first network core of the first network and a second network core of the second network over a side haul communication channel. The exchange of content results in a first base station transceiver of the first network being capable of communicating with first network components of the first network core and with mirrored instances of second network components of the second network core within the first network core. The method also includes controlling, with the first network core, communications through the first base station transceiver using the second content included in the mirrored instances of the second network components.

Abstract: A method is provided for waking up a first mode of a multimode mobile radio unit. An event driven paging server determines that the first mode of the multimode mobile unit should be woken up. A wakeup message is sent to a second mobile unit. The second mobile unit sends a wakeup message to a second mode of the multimode mobile unit using non-cellular technology, such as low-power short-range communication such as Bluetooth. The second mode of the multimode mobile radio unit receives the wakeup message and wakes up the first mode of the multimode mobile unit.

Abstract: Disclosed herein are methods and systems for scheduling transmission of uplink communication. One embodiment takes the form of a process carried out by a first-radio-access-network-(RAN) entity in a first RAN, where the first RAN has a first-RAN uplink that is time-synchronized with a second-RAN uplink of a second RAN. The first-RAN entity detects an uplink-scheduling event associated with a mobile radio, and the first-RAN entity also identifies a second-RAN-uplink-transmission time slot for the mobile radio. The first-RAN entity schedules the mobile radio to transmit first-RAN-uplink communication, which is associated with the detected uplink-scheduling event, during a first-RAN-uplink time slot that does not overlap the identified second-RAN-uplink-transmission time slot.

Abstract: A Long Term Evolution (LTE) Concentrator and Distributor system and method extends geographical coverage while minimizing Evolved Node B (eNB) deployments. The system and method use a distributed array of Wide Band Receiver Transmitter (WBRT) devices (i.e., RF Heads, RFH, including antennas) connected via wide-band links to a central standard LTE eNB through a novel LTE Concentrator-Distributor (LTE-CD) which is an uplink (smart optimal) concentrator and downlink simulcast distributor. The eNB downlink signal (baseband or modulated RF) is distributed in synchronization (simulcast) through the LTE-CD to all WBRTs for downlink simulcast transmission to all UEs in the coverage area. The WBRTs receive uplink signals from user equipment, UE, devices in a coverage area, send the uplink signals (baseband or modulated RF) to the LTE-CD which optimally combines all received signals into one best uplink signal that is sent (in baseband or modulated RF) to the eNB.

Abstract: Methods for inter-mixer communication enable a “self-formed” cascaded mixer node tree topology. One method enables inter-mixer node signaling and includes first selecting a plurality of media flow payloads at a first cascaded mixer node. A set of conference payloads are generated and each include the media flow payloads from the plurality of media flow payloads that are part of the same conference call, an identifier for the conference call, and a node identifier for each media flow in the conference call. For each media flow in the conference call, each conference payload further identifies whether the first cascaded mixer node is a root node or a leaf node. The set of conference payloads are bundled into a single packet and sent to a second cascaded mixer node. Another method enables the “self-forming” of the mixer node tree topology. Yet another method enables active talker identification within the “self-formed” tree topology.

Abstract: A voice activity detector (100) includes a frame divider (201) for dividing frames of an input signal into consecutive sub-frames, an energy level estimator (202) for estimating an energy level of the input signal in each of the consecutive sub-frames, a noise eliminator (203) for analyzing the estimated energy levels of sets of the sub-frames to detect and eliminate from enhancement noise sub-frames and to indicate remaining sub-frames as speech sub-frames, and an energy level enhancer (205) for enhancing the estimated energy level for each of the indicated speech sub-frames by an amount which relates to a detected change of the estimated energy level for a current speech sub-frame relative to that for neighboring speech sub-frames.

Abstract: In accordance with the preferred embodiments of the present invention, a method (400) and a base station (140) for providing a plurality of transmit diversity protocols in a wireless communication system are described herein. In particular, the base station (140) generates a first signal based on a first data stream with a first pilot and a second data stream with a second pilot. That is, the first signal includes the first and second pilots. The first pilot is based on a first orthogonal code and the second pilot is based on a second orthogonal code. The base station (140) generates a second signal based on the first data stream with the first pilot and the second data stream with the second pilot such that the second signal including the first and second pilots is diverse relative to the first signal. Further, the base station (140) phase-shift modulates the first signal to produce a phase-shift modulated signal.
