  • Patent number: 10743147
    Abstract: A network controller, a user equipment (UE) device, and associated methods for conducting intelligent enhanced multimedia broadcast multicast services (eMBMS). A network controller receives user preference information and location information from a plurality of UEs. The network controller selects one or more data packages to transmit using eMBMS in one or more broadcast regions based on the user preference information and the location information. The one or more data packages may comprise an updated machine learning model in a distributed learning application. The network controller provides an indication to a remote device to broadcast the one or more data packages in the respective one or more broadcast regions using eMBMS.

  • Patent number: 10652925
    Abstract: Methods and apparatus to support channel access control for keyless vehicle entry systems are disclosed. An initiating central wireless device of a wireless personal area network (WPAN) queries multiple responding peripheral wireless devices to perform ranging for distance and/or angle of arrival data, where the multiple peripheral wireless devices coordinate responses to minimize interference, avoid overlapping transmissions, and reduce time to complete ranging. Ranging frames are divided into multiple ranging time slots, where each ranging time slot can accommodate a full ranging cycle between the central and peripheral wireless devices. The central wireless device determines which ranging time slot to use based on estimates of communication channel interference and on a number of received responses from the peripheral wireless devices. Ranging measurements are provided to a controller of a vehicle that houses the peripheral wireless devices to determine whether to permit vehicle access.

  • Publication number: 20190082443
    Abstract: An electronic device that determines a transmission schedule is described. This electronic device may include an interface circuit that communicates with a recipient electronic device. During operation, the electronic device may receive a frame with scheduling-request information that is associated with the recipient electronic device. The scheduling-request information may include a buffer status report for persistent traffic, and the frame may be compatible with an IEEE 802.11 communication protocol. For example, the frame may include a scheduling-request management frame. Alternatively, the frame may include a data frame and the scheduling-request information may be included in a media access control (MAC) frame header, such as a high-efficiency (HE) variant high-throughput (HT) control header. Then, the electronic device may determine the transmission schedule based at least in part on the scheduling-request information.

  • Patent number: 9780922
    Abstract: A method and apparatus for increasing the data rate and providing antenna diversity using multiple transmit antennas utilize a set of bits of a digital signal to generate a codeword. Delay elements may be provided in antenna output channels, or, with suitable code construction, delay may be omitted. n signals represent n symbols of a codeword are transmitted with n different transmit antennas. At the receiver, the noisy received sequence is decoded. The parallel transmission and channel coding enables an increase the data rate over previous techniques, and recovery even under fading conditions. The channel coding may be concatenated with error correction codes under appropriate conditions.

  • Patent number: 9544094
    Abstract: Block-encoded transmissions of a multi-antenna terminal unit are effectively detected in the presence of co-channel interfering transmissions when the base station has a plurality of antennas, and interference cancellation is combined with maximum likelihood decoding. More specifically, the signals received at the base station antennas are combined in a linear combination that relates to the channel coefficients between the various transmitting terminal units and the base antennas. By selecting proper coefficients for the linear combination and choosing probable transmitted signals that minimize a minimum mean squared error function, the signals of the various terminal units are canceled when detecting the signal of a particular unit. In another embodiment of the invention, the basic approach is used to obtain an initial estimate of the signals transmitted by one terminal unit, and the contribution of those signals is removed from the received signals prior to detecting the signals of other terminal units.

  • Patent number: 9374749
    Abstract: Certain embodiments of the present disclosure provide a method for switching radio frequency (RF) carriers that serve communication between a base station (BS) and a mobile station (MS). The switching of carriers can be viewed as a handoff procedure between two different RF carriers within the same BS. A simplified handoff procedure for switching of RF carriers can be applied when the MS switches its physical connection from a primary RF carrier to a secondary RF carrier, as well as in the case when the BS decides to move the MS from one primary RF carrier to another primary RF carrier.

  • Patent number: 8724749
    Abstract: Information symbols are transmitted simultaneously on independent streams using the same spreading code but from different transmit antennas at the transmitter. These simultaneous data stream could be intended for the same user (and thereby the data rate for any particular user can be increased) or for different users (thereby increasing the system capacity). Each stream of data can belong to a different signal constellation and use a different channel code. At the receiver, a number of receive antennas equal to at least the number of multiple data streams is used to separate the different data streams. We consider two different cases. The first one when no transmit diversity is used (this case can also include the case when transmit diversity with simple antenna weighting is used) and the second when transmit diversity with space-time block coding is used.
