  • Patent number: 10966264
    Abstract: A communication system includes a control wireless station. One or more data payload-conveying wireless stations rely on the control wireless station to provide control information to a mobile communication device to control conveyance of data over one or more data channels to the mobile communication device. For example, to connect to a remote network, a mobile communication device establishes a first wireless communication link with the control wireless station. The mobile communication device establishes a second wireless communication link with a data conveying wireless station. The first wireless link conveys control information from the control wireless station to the mobile communication device. The second wireless link conveys data payload information. The control information conveyed over the first wireless link controls conveyance of the data payload information over the second wireless communication link.

  • Patent number: 10938521
    Abstract: Provided is a terminal device that is capable of improving the characteristics of a response signal having poor transmission characteristics when ARQ is utilized in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. At the time of channel selection, a control unit selects a resource used in sending a response signal from among specific PUCCH resources notified in advance from a base station and PUCCH resources mapped to a CCE, and controls the transmission of the response signal. A response signal generating unit supports implicit signaling with respect to any given response signal, and at the same time as supporting LTE fallback from 2CC, uses a mapping method that, between bits, smooths the number of PUCCH resources that can determine ACK/NACK simply by determining the PUCCH resource regarding which the response signal had notified.

  • Patent number: 10932264
    Abstract: The disclosure is related to a method and a system for adjusting a communication channel based on a signal scan result. The system includes wireless gateway modules, a wireless transceiver module and a control circuit. The control circuit determines whether or not the wireless transceiver module conducts any transmission task. The wireless transceiver module is activated to scan signals over a selected frequency when it is available. Multiple scan results can be obtained when the scanning process is repeatedly conducted in different frequencies. Signal information is recorded in a signal scan table. Thus, if the system determines the frequency needs to be adjusted based on a transmission status, one of the frequencies recorded in the table can be chosen and set for the wireless gateway module and a transmission frequency for a terminal node is modified.

  • Patent number: 10848940
    Abstract: Systems and methods are disclosed for exchanging real-time data between vehicle systems by receiving, at a first source system, a request for data from a requestor and, based on determining that the first source system does not have all requested data, querying an operations center for missing data. Then, based on determining that the operations center does not have all missing data, the operations center is queried for a list comprising candidate source systems. Upon identifying a next source system from the list, the next source system is queried for missing data, and the next source system is removed from the list. Based on whether the next source system has all missing data, either all missing data is transmitted to the requestor, or, the process of finding and querying for the missing data is iteratively performed until all missing data is received or the list is empty.
