  • Patent number: 10805217
    Abstract: Control plane devices are selected by a Multimedia Broadcast Multicast Service Gateway (MGW) based on session exchange procedural triggers received from a Broadcast Multicast Service Center (BMSC). In one aspect, the MGW can employ a serving area-based Domain Name System (DNS) query/response exchange for control plane device selection that simplifies the overall complex broadcast core network architecture and design. Additionally or optionally, the MGW can employ other factors, such as, but not limited to, round trip time (RTT), load information, active/inactive link status, etc. to select the control plane devices that are to be utilized for establishing the end-to-end control plane message exchanges.

  • Patent number: 10743201
    Abstract: Joint demodulation of a desired transmission and an interfering transmission received from an interfering cell with an unknown combination of transmission parameters is performed. For each subcarrier, an exhaustive search for the serving cell symbols and projection for the interfering cell symbols is performed for tested hypotheses of the interfering cell, by minimizing a whitened noise parabola for each combination of searched hypothesis and hyper constellation point of the serving cell. A constellation point for the interfering cell that is closest to the minimum point of the parabola is selected, where coefficients of the parabola are calculated once for each subgroup of four modulation types of the interfering cell. A measure of likelihood for each of the tested hypotheses is calculated. A cumulative measure of likelihood for each of the tested hypotheses is calculated, and the most likely hypothesis is selected based on the cumulative measure of likelihood.

  • Patent number: 10735168
    Abstract: A method for wireless interrogation of data from a passive element. A first high frequency signal sent to the element excites the element to transmit a response signal which is received and mixed with a reference signal in a mixer, generating a data signal. The data signal is evaluated to extract data. A second high frequency signal generated from the same frequency reference as the first frequency signal is used as a reference signal. A control signal is generated by mixing the reference and first frequency signals. The data signal is bandpass-filtered in analog form and is converted, with the control signal, to a digital signal and digital control signal which are then each bandpass-filtered in digital form. The digital data and digital control signals are correlated to form a result signal so that a digital coherence is achieved. Raw data representing the data are obtained from the result signal.
