Patent number: 10772135Abstract: A contending radio node (200) is configured for attempting contention-based random access. The contending radio node (200) obtains a timing advance sequence that is susceptible to contention. The contending radio node (200) transmits, using the same transmission advancement timing, the timing advance sequence and a contention-resolving identity to a recipient radio node (250). Responsive to that transmission, the contending radio node (200) receives a response signal that indicates a contention-resolving identity and a timing advance. The contending radio node (200) resolves any contention in its favor when the contention-resolving identity indicated by the response signal corresponds to the contention-resolving identity that the contending radio node (200) transmitted. The contending radio node (200), responsive to resolving the contention in its favor, adjusts its transmission advancement timing according to the timing advance indicated by the response signal.Type: GrantFiled: October 28, 2016Date of Patent: September 8, 2020Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Henrik Sahlin, Amitav Mukherjee

Patent number: 10764181Abstract: Packet processors or other devices with packet processing pipelines may implement pipelined evaluations of algorithmic forwarding route lookups. As network packets are received, a destination address for the network packets may be divided into different possible prefix lengths and corresponding entries in a routing table for the different possible prefix lengths may be determined according to a hash scheme for the routing table. The entry values may be read from the routing table and evaluated at subsequent stages to identify the entry with a longest prefix match with respect to the destination address for the network packet. The routing table may include entries for different types of network packets and may be configured to include virtual routing and forwarding for network packets.Type: GrantFiled: November 16, 2018Date of Patent: September 1, 2020Assignee: Amazon Technologies, Inc.Inventors: Bijendra Singh, Thomas A.

Patent number: 10764184Abstract: In one embodiment, the system identifies geographic areas covered by a communication network. The system determines, for each identified geographic area, a network performance metric for the identified geographic area based on a difference between: (1) a first average network speed of the communication network in the identified geographic area during prior time periods in which the communication network is busy, and (2) a second average network speed of the communication network in the identified geographic area during second prior time periods in which the communication network is not busy. The system compares the respective performance metrics of the geographic areas to a threshold network performance metric, which is determined by a congestion-analysis machine learning (ML) model. The system identifies traffic congestions in one or more of the identified geographic areas having a determined network performance metric below the threshold network performance metric.Type: GrantFiled: October 9, 2018Date of Patent: September 1, 2020Assignee: Facebook, Inc.Inventors: Ying Li, Martinus Arnold de Jongh, Vincent Gonguet, James Donovan, Laurent Corigliano

Patent number: 10721044Abstract: Systems and methods are disclosed for minimizing latency between receipt of a NACK at a base station from a user equipment (UE) and retransmission of data to the UE. Time constraints for processing the ACK/NACK are relaxed so the base station can decode the ACK/NACK to determine whether a NACK has been received and then prepare for transmission of the appropriate data to the UE in the immediately following transmission time interval (TTI). These constraints are relaxed by separating download data indicator (DDI) from the PDCCH control data and delaying transmission of the DDI until decoding of the ACK/NACK.Type: GrantFiled: March 15, 2016Date of Patent: July 21, 2020Assignee: QUALCOMM IncorporatedInventors: Peter Pui Lok Ang, Jing Jiang, Krishna Kiran Mukkavilli, Tingfang Ji, John Edward Smee, Jamie Menjay Lin, Rotem Cooper, Michael Alexander Howard
