Abstract: A wireless communication device is configured to generate frames based on any of a number of different frame formats for transmission to one or more other recipient wireless communication devices. The frame may be implemented to include data intended for two or more recipient devices. The device encodes first data intended for a first recipient device using first one or more coding parameters and encodes second data intended for a second recipient device using second one or more coding parameters. The manner by which the first and second data have been encoded is indicated within one or more other fields within the frames based on the selected frame format. In one example, a single preamble specifies the first and second one or more coding parameters. In another example, an initial preamble and one or more respective sub-preambles specify the first and second one or more coding parameters.

Abstract: Aspects of a method and system for mitigating interference among femtocells via intelligent channel selection are provided. In this regard, signals which may interfere with cellular communications between a femtocell and a cellular communication device may be detected via the femtocell. Based on the detection, the femtocell may be configured to transmit and/or receive signals on one or more frequencies and/or channels. The one or more frequencies and/or channels may be determined in the femtocell and/or in a network management entity. Detecting interfering signals and configuring the one or more femtocells may occur periodically, upon installation of a femtocell, upon power-up of a femtocell, and/or upon command from a network administrator. The results of the detection may be communicated to one or more other femtocells and/or to a network management entity.

Abstract: A transceiver includes a receiver section and a transmitter section. The receiver section converts an inbound Multiple Frequency Bands Multiple Standards (MFBMS) signal into a down converted signal, wherein the inbound MFBMS signal includes a desired signal component and an undesired signal component. In addition, the receiver section determines spectral positioning of the undesired signal component with respect to the desired signal component and adjusts at least one of the MFBMS signal and the down converted signal based on the spectral positioning to substantially reduce adverse affects of the undesired signal component on the desired signal component to produce an adjusted signal. The transmitter section converts an outbound symbol stream into an outbound MFBMS signal.

Abstract: A device for facilitating cellular-wireless local area network (WLAN) interworking may include at least one processor circuit. The processor circuit may be configured to receive a packet including a first tunnel identifier and addressed to a user equipment (UE). The processor circuit may be configured to identify a radio bearer associated with the first tunnel identifier, where the radio bearer is configured to facilitate transmission of the packet to the UE via cellular communications. The processor circuit may be configured to determine whether the radio bearer has been offloaded over a WLAN. The processor circuit may be configured to, when the radio bearer has been offloaded over the WLAN, identify a second tunnel identifier mapped to the radio bearer; encapsulate the packet based on the second tunnel identifier, where the encapsulated packet includes the second tunnel identifier; and transmit the encapsulated packet to the UE over the WLAN.

Abstract: Transmission coordination within multiple user, multiple access, and/or MIMO wireless communications. Within wireless communication systems, there can be various wireless communication devices therein that are not all compliant with a common capability set, communication protocol, communication standard, recommended practice, etc. For example, some communication systems may have some wireless communication devices characterized as ‘legacy’ wireless communication devices, and other wireless communication devices therein may be newer and compliant with newer capability sets, communication protocols, communication standards, recommended practices, etc. In such instances, coordination of transmissions among the various wireless communication devices may be made, when performing simultaneous transmissions, by ensuring that transmissions of devices on different channels is made when aligned on a common boundary of an OFDM symbol. Alternatively, such simultaneous transmissions may be made when offset by some multiple of OFDM symbol duration. When performing non-simultaneous transmissions, transmissions may be made based on channel availability.

Abstract: In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point operating in an unlicensed frequency band using a first RAT receives, from a second access point operating in the unlicensed frequency band using a second RAT, information regarding operation of the second access point in the unlicensed frequency band. It is determined, using the received information, that the first access point or the second access point is using a first share of the unlicensed frequency band that is below a predetermined threshold, indicating an imbalance of usage between the first RAT and the second RAT. A transmission parameter of the first access point for operating in the unlicensed frequency band using the first RAT is adjusted according to the determination. The first access point transmits the one or more packets using the adjusted transmission parameter, to cause the first access point or the second access point to use an updated share of the unlicensed frequency band that is closer to the predetermined threshold than the first share.
