  • Patent number: 10749737
    Abstract: Disclosed is an interoperability gateway system that provides backup connection between a dispatch center and a Land Mobile Radio (LMR) system in the event the dispatch center is disconnected from the LMR system. In general, this may be accomplished by providing an RF link between the disconnected site and the interoperability gateway via a controller, or interoperability site network interface (ISNI), that is activated when the dispatch center is disconnected from the LMR system. The interoperability gateway provides the backup connection by allocating a control station for each channel available at the disconnected LMR system. When compared to conventional dispatch console backup schemes, the disclosed interoperability gateway system greatly reduces the equipment needed to provide dispatch console backup, thereby decreasing equipment and operation costs, and simplifying operation by providing a solution that is virtually transparent to the dispatcher.

  • Patent number: 10555310
    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a base station may communicate with multiple user equipment (UEs) that support different features. As described herein, a base station may schedule communications on a set of resources with UEs that support a particular feature. The base station may transmit an indication (e.g., to one or more UEs) of the feature that is to be supported for a UE to communicate on the set of resources, and the UE may receive the indication and determine whether to communicate on the set of resources based on determining if the particular feature is supported. Accordingly, a UE that fails to support the feature may reduce processing costs and save power by ignoring the set of resources.

    Abstract: Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.

    Abstract: The objective of the present invention is to provide a relay apparatus capable of performing normal relay transmission for broadcast waves by preventing effects caused by wraparound in a relay apparatus. For broadcast waves received by a relay apparatus (2), the same broadcast data are placed in each of a defined segment (f0) and a first segment (f1) other than the defined segment, whereupon the relay apparatus removes broadcast data for the defined segment (f0) from the received broadcast waves, and transmits broadcast waves in which the broadcast data for the first segment (f1) have been exchanged with each of the defined segment (f0) and a second segment (f2) other than the defined segment and the first segment. As a result, the defined segment (f0) which imparts wraparound effects to the received broadcast waves is removed, and therefore, it is possible to perform normal relay transmission of the broadcast waves.

An MCS determining unit 17 provided in the transmission determining unit 16 determines an MCS for the relay signal. A transmission instruction generated by the transmission determining unit 16 is output to a buffer 11 and an ACK/NACK generating unit 19. The determined MCS is output to an error correction coding unit 12 and a modulation unit 13.

  • Patent number: 8565673
    Abstract: A hierarchical WRAN includes a relay station (RS) possessing dual roles. A RS acts from the perspective of a base station (BS) as a consumer premise equipment (CPE) terminal just as any other first tier CPE terminal. Simultaneously, the RS, from the perspective of other second tier CPEs, acts as a BS providing all of the functional capabilities of a BS. The RS includes dual medium access control (MAC) functions in which a first MAC function serves to interface the RS with the BS while the second MAC function serves to interface the RS with the at least one CPE terminal. The RS further includes a convergence layer that maps, at the RS, the first MAC to the second MAC. The dual MAC capability of the RS enables the RS to pipeline frame transmission in both single and multi-channel operations.

  • Patent number: 8520655
    Abstract: One object of the present invention is to effectively utilize adaptive modulation and improve stability of wireless communication, without departing from standards, by independently controlling MCSs of retransmission data and usual data and using MCS suitable for each data. In the wireless communication system of the present invention, a frame, in which an error occurs, in both a transmitting device and a receiving device and the error part are specified, and MCS used in the frame is specified. Therefore, it is possible to modulate/demodulate the error part based on desired MCS without loading MCS on HARQ.
