Patent number: 10820349Abstract: Improved protocols for wireless networking are disclosed. At low/zero marginal cost, embodiments enable increased throughput and reduced delays at high traffic density, while greatly reducing message collisions and ensuring that each user is able to transmit in order. By providing a sequencing advantage to nodes that have already been delayed, embodiments can eliminate the “blocked node” problem in which some nodes are suppressed indefinitely while other nodes are allowed to dominate a communication channel with multiple transmissions. As the wireless traffic density soars in the coming years, embodiments can improve system utility while enhancing user satisfaction by providing higher message success rates, reducing user frustration, minimizing message delays and message collisions, and eliminating node blocking. An array of embodiments can be implemented on existing and planned equipment with appropriate programming.Type: GrantFiled: November 27, 2019Date of Patent: October 27, 2020Assignee: AUTONOMOUS ROADWAY INTELLIGENCE, LLCInventors: David E.

Patent number: 10820347Abstract: A dynamic configuration of crest factor reduction in a licensed assisted access radio system. A processing device comprises a detecting block, a clipping pulse generator, a first storage block, a selecting block, a full clipping block and a simplified clipping block. The detecting block performs a listen-before-talk (LBT) procedure on a plurality of carriers in parallel and generates a trigger signal in response to LBT success on one or more carriers. The clipping pulse generator generates, for the carrier(s) with LBT success, a clipping pulse within a time period from the receipt of the trigger signal to the start of user traffic transmission. The first storage block stores the clipping pulse for use by the full clipping block. The selecting block selects the full clipping block when there is user traffic on the carrier(s) and selects the simplified clipping block when there is no user traffic on the carrier(s).Type: GrantFiled: March 24, 2020Date of Patent: October 27, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Gan Wen, Jinsong Yang

Patent number: 10728127Abstract: A method and apparatus for maintaining network connectivity over power lines is disclosed. Such network connectivity is maintained even if various customers are covered by different power line networks or if one or more power lines in a network are unavailable to transmit data. More particularly, in order to bridge a gap in a power line network, one or more messages are extracted from a first node in a power line network and are then transmitted to a second node via free space transmission. When those messages are received at the second node, the message is injected back into the power line on the other side of a gap in power line coverage. This method of transmission backup will continue until power line connectivity is restore upon which the preferred method will be selected and used.Type: GrantFiled: January 2, 2019Date of Patent: July 28, 2020Assignee: AT&T Intellectual Property II, L.P.Inventors: Alan K.

Patent number: 10659205Abstract: According to one aspect of the teachings herein, a base station (20) schedules the transmission of uplink reference signals by a wireless device (16) separately from scheduling uplink data transmissions by the device (16). The separate scheduling may be done at specific times, under specific conditions, and with respect to specific devices (16) or groups of devices (16). Separate scheduling allows, for example, the base station (20) to use smaller scheduling intervals that are possible when uplink reference signals are integrally included in any scheduled uplink data transmission. As a further advantage, the density or number of uplink reference signal transmissions by a given device (16) can be adapted, e.g., based on channel conditions, data transmission formats, etc.Type: GrantFiled: August 10, 2016Date of Patent: May 19, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mattias Andersson, Niklas Andgart, David Astely, Helka-Liina Määttanen, Henrik Sahlin

Patent number: 10659103Abstract: Systems and methods are provided for synchronizing multiple channels in an access network, where the multiple channels are neighboring channels such that a guard band between them or use of a diplexer to prevent inter-channel interference is not required. Synchronization is achieved by defining channel MAP (media access plan) cycle structures such that all channels work in the same direction (upstream US or downstream DS) at any given time. Moreover, the network controller of channel may send out a beacon to allow new nodes to join. A long MAP cycle (402) may be followed by three consecutive regular MAP cycles (404, 406), and (408). These MAP cycles are repeated between beacon transmissions. Synchronization allows multiple channels to be configured contiguous (without a guard band between neighbouring channels) and without utilizing diplexers. A plurality of customer premises equipment may operate on each of the communications channels.Type: GrantFiled: October 16, 2018Date of Patent: May 19, 2020Assignee: Entropic Communications, LLCInventor: Zong Wu

Patent number: 10660087Abstract: An autonomously dispersed type wireless network is suitably formed with communication stations avoiding collision of beacons transmitted one to another. In the event that the range of reach of airwaves change and a receivable state is created and beacons collide, a communication station changes the beacon transmission position of itself in response to receiving a beacon from another station at a timing immediately prior to transmission to its own beacon. Also, in the event that beacon collision is exposed due to emergence of a new communication which can perform reception from two systems out of airwave range of each other, the newly-participating station requests one of the communication stations of which the beacons are colliding to change the beacon transmission timing.Type: GrantFiled: September 24, 2015Date of Patent: May 19, 2020Assignee: SONY CORPORATIONInventor: Kazuyuki Sakoda
