    Abstract: A method of modulating and demodulating superposed signals for MUST scheme is proposed. A transmitter takes bit sequences intended for multiple receivers under MUST scheme to go through a “bit sequence to constellation points” mapper before entering the modulators to satisfy the Gray coding rule and to achieve high demodulation performance for the receivers. In a first method, each bit sequence is assigned for each constellation point on the constellation map to satisfy one or more conditions under different power split factors. In a second method, the constellation map is divided into sub-regions according to the clustering of the constellation points for bit sequence assignment. A near-UE may use an ML receiver for demodulation and decoding the superposed signal. A far-UE may use an ML receiver or an MMSE receiver for demodulation and decoding the superposed signal.

  • Patent number: 9998995
    Abstract: A method for reducing self-interference in a wireless network, such as a Link 16 network, while maintaining simultaneous multiple access takes advantage of the physical proximity of nodes in a localized subnetwork, such as a fighter-to-fighter subnetwork in a flight wing, by actively reducing the transmit powers used for subnet messages between the nodes. Calibration messages such as Precise Participant Location and Identification (PPLI) messages are exchanged between all of the nodes of the localized subnetwork, from which each node determines the identities, transmit powers, noise levels, and SNRs of all of the other nodes. The node then determines a link margin for other nodes, and sets its transmit power to a “safe” level for the subnetwork according to the lowest link margin.

  • Patent number: 9942805
    Abstract: The disclosure provides for a UE handling messages in wireless communication. The disclosure provides for a UE partially exchanging a first signaling-related message associated with a first UE configuration with a network entity and triggering a state transition message that initiates a change to a second UE configuration different from the first UE configuration. In an aspect, the UE determines that the first message has not been successfully received or successfully transmitted. In an aspect, the UE sends an indication message to coordinate discarding of the first message with the network entity and receives, after sending the indication message, a second signaling-related message associated with the second UE configuration. In another aspect, the UE, after partially sending a signaling-related message, receives a reconfiguration request associated with a second UE configuration. In an aspect, the UE determines that the message has not been successfully transmitted and causes a reconfiguration failure.

  • Patent number: 9794801
    Abstract: Reliable multicast delivery in wireless communication, even when a WS doesn't know its AP, is determined at the AP without the sending device. Multicast packets are received at each AP having destinations. Without altering those packets, the AP encapsulates them in an A-MSDU packet. Each A-MSDU packet is sent individually to each destination, and might encapsulate more than one multicast packet. Destinations might receive two streaming messages faster than if sent separately. AP's might choose a 1st multiple of multicast packets from a 1st source, a 2nd, different, multiple of multicast packets from a 2nd source, and a single multicast packet from a 3rd source. Individualized optimization of transmission parameters for each A-MSDU packet and each multicast packet therein. Individualized optimization of transmission parameters for the A-MSDU packet for each destination. The AP collectively optimizes delivery of distinct multicast packets to different destinations.
