Abstract: 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.

The wireless communication device selects, based on the determination, at least one of performing a backoff or continuing to monitor the spectrum.

Abstract: 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.

Abstract: 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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) utilizing enhanced carrier aggregation (eCA) may identify a limit to the number of channel state feedback (CSF) processes it is capable of supporting. The UE may transmit an indication of this limit to a base station, which may configure the UE for channel state reporting, and send channel state reporting triggers according to the indicated limit. The UE's determination of the limit to the number of CSF processes may be based on various transmit or receive antenna configurations. A single trigger may correspond to reports covering multiple subframes and/or component carriers. The base station may also arrange the channel state reporting configuration to reduce the peak number of channel state reports that the UE processes during each subframe. The UE may also determine that a number of channel state processes needed to support channel state reporting in a subframe exceeds its capacity.
