  • Patent number: 11356978
    Abstract: A relay node receives a data block containing multiplexed data streams intended for multiple user equipment (UE) devices being served by the relay node. The relay node extracts the data streams from the data block and allocates them each to a separate narrowband channel that is associated with a particular UE device. The relay node repeatedly transmits the narrowband channels to the UE devices in a broadcast transmission that is transmitted for a predetermined number of repetitions. Each UE device decodes their own respective narrowband channel to obtain the data stream intended for the UE device associated with a particular narrowband channel. A feedback mechanism is utilized by the relay node to determine whether to retransmit a data packet or a new data packet in subsequent broadcast transmissions.

  • Patent number: 11314955
    Abstract: The disclosure describes an RFID system having chip-based novel Simple Random-Access Procedure (SRAP) and Dynamic Simple Random-Access Procedure (DSRAP) tags, and chip-less time and frequency coded tags, for inventory management. The SRAP process contains static (pre-defined) size Frame Structures, and RFID tags compete for network resources by transmitting random preambles to contend for resources to send its Tag-ID to the RFID Reader. The DSRAP process contains dynamic (changing) size Frame Structures and is more efficient than SRAP if the number of tags is lower. The disclosed memory-based variants, save the orthogonal preambles in the tag's memory to reduce the number of transmitted bits and processing necessary to calculate the preambles. To further improve system efficiency and reduce the number of transmitted bits, disclosed memory-based variants may use a pre-defined memory-based modulation (QAM) signal in the memory of the transmitter of the Tags.

  • Patent number: RE49070
    Abstract: A method for calculating delay in a distributed antenna system includes sending a ping initiation message from a remote node to a host node in a distributed antenna system. The ping initiation message uniquely identifies a first communication port of the remote node to the host node with a unique identification. The method also includes receiving a ping reply message at the remote node. The ping reply message corresponds to the ping initiation message and also uniquely identifies the first communication port of the remote node with the unique identification. The method also includes determining, at the remote node, whether the ping reply message corresponds to the first communication port of the remote node based on the unique identification. The method also includes, when the ping reply message corresponds to the first communication port of the remote node, calculating the round-trip time delay between sending the ping initiation message and receiving the ping reply message at the remote node.
