Patent number: 10057154Abstract: Systems and methods that use adaptive control of communication protocol parameters in a network of moving things. Each network device may share information identifying communication protocol parameters used by the network device through periodic broadcasts, which may be received by neighboring network devices that are within communication range. The neighboring network devices may then adjust their own communication protocol parameters accordingly when attempting to communicate with the first network device and their own neighboring network devices. Network devices that have not received the shared information may use information about their geographic location and the geographic location of neighboring network devices to estimate values of some communication protocol parameters that will provide more effective communication.Type: GrantFiled: September 5, 2017Date of Patent: August 21, 2018Assignee: Veniam, Inc.Inventor: Carlos Eduardo Braga Ameixieira

Patent number: 10034273Abstract: A system and method is disclosed for resource block-specific control signaling in a communication system. Communication data is transmitted using a transmission channel comprising a plurality of resource blocks defined by allocating time-frequency slots in a transmission resource. Resource block control information is transmitted in a “feed-forward” manner to a user end (UE) or group of UEs using channels physically mapped into scheduled resource blocks (RBs) for that user or group of users. Embodiments of the invention provide an RB-specific control channel that comprises RB control elements that are embedded within scheduled resource blocks. The invention, therefore, reduces the amount of control information that must be transmitted by common or shared control channels.Type: GrantFiled: September 22, 2017Date of Patent: July 24, 2018Assignee: Apple Inc.Inventor: Jayesh H.

Patent number: 9942068Abstract: Devices and methods for enabling the use of legacy-equipment in light of evolving and conflicting standards used by new-equipment are provided. When a standard for transmission on a network conflicts with an existing standard, legacy-equipment, which uses the existing standard, may prevent the implementation of new-equipment, which uses a new or updated standard, on the network. Although many standards strive for backwards compatibility or interoperability with other standards, not all standards are compatible, or they achieve backwards compatibility by disabling features of new-equipment until legacy-equipment has been upgraded or removed from the network. Devices and methods therefore are provided to isolate legacy-equipment and new-equipment so that the new features of evolving standards may be implemented for new-equipment without materially impacting the operation of legacy-equipment.Type: GrantFiled: September 3, 2015Date of Patent: April 10, 2018Assignee: COX COMMUNICATIONS, INC.Inventor: Christopher James Topazi
