The PRACH channel and the one or more uplink channels are aligned.

Abstract: Prefix entries are efficiently stored at a networking device for performance of a longest prefix match against the stored entries. A prefix entry generally refers to a data entry which maps a particular prefix to one or more actions to be performed by a networking device with respect to network packets or other data structures associated with a network packet that matches the particular prefix. In the context of a router networking device handling a data packet, the one or more actions may include, for example, forwarding a received network packet to a particular “next hop” networking device in order to progress the network packet towards its final destination, applying firewall rule(s), manipulating the packet, and so forth. To reduce a total amount of space occupied by a prefix tree in storage, each of the nodes of a prefix tree may be configured to store only an incremental portion of a prefix relative to its parent node.

Abstract: Channel State Information (CSI) is reported by a subscriber station to a base station. The CSI is reported periodically for at least two physical uplink control channels (PUCCH). In case of a collision between a report for a first PUCCH and a report for the second PUCCH, each of the report types is partitioned into one of a number of classes, which include: a first class for rank indicator related report types and wideband (WB) W1 report types; a second class for WB report types or WB channel quality indicator report types; and a third class for subband related report types or W1 report types. A priority rule assigns a priority to each of the classes. The CSI feedback reports are transmitted according to the priority rule such that the report type included in a higher class is transmitted and the report type included in the lower class are dropped.

Abstract: A wireless network interface device selects a guard interval from a set of guard intervals including a first guard interval, a second guard interval, and a third guard interval. The first guard interval has a length that is different than a length of the second guard interval and a length of the third guard interval, and the length of the second guard interval is different than the length of the third guard interval. The wireless network interface device generates a preamble of a data unit to include: a legacy signal field, a repetition of the legacy field, and a non-legacy field that includes a field that indicates the selected guard interval. The wireless network interface device generates a data portion of the data unit, including generating orthogonal frequency division multiplexing (OFDM) symbols of the data portion using the selected guard interval.

Abstract: According to embodiments of the present disclosure, a method, apparatus, device and storage medium for managing traffic data of a client application is provided. The method described herein comprises: detecting a transmission of user data of a target user from the client application to a server; analyzing the traffic data of the transmission at different layers of the transmission based on types of the traffic data; and in accordance with a determination that the analysis indicates that the traffic data satisfies a data exchange constraint corresponding to the target user, transmitting the traffic data to a server in compliance with the data exchange constraint. In this way, by analyzing the traffic data at different layers of the transmission and restricting traffic data that does not satisfy the data exchange constraint, it is possible to effectively prevent user data from being transmitted to unauthorized servers via various types of traffic data.

Abstract: An Orthogonal Time Frequency Space Modulation (OTFS) modulation scheme that maps data symbols, along with optional pilot symbols, using a symplectic-like transformation such as a 2D Fourier transform and optional scrambling operation, into a complex wave aggregate and be backward compatible with legacy OFDM systems, is described. This wave aggregate may be processed for transmission by selecting portions of the aggregate according to various time and frequency intervals. The output from this process can be used to modulate transmitted waveforms according to various time intervals over a plurality of narrow-band subcarriers, often by using mutually orthogonal subcarrier “tones” or carrier frequencies. The entire wave aggregate may be transmitted over various time intervals. At the receiver, an inverse of this process can be used to both characterize the data channel and to correct the received signals for channel distortions, thus receiving a clear form of the original data symbols.

Abstract: The present disclosure provides an approach for scaling the number of VNFs in a data center without scaling the number of control sessions between VNFs and a data center gateway. The approach includes opening a session between a VNF and a route server, rather than between the VNF and the gateway, when the VNF needs to send its connectivity information to the gateway. The VNF sends its connectivity information to the route server, and the route server forwards the connectivity information to the gateway. The gateway receives connectivity information of a plurality of VNFs in the data center from the route server rather than from each of the VNFs individually. The connectivity information is then used to send packets, by the gateway to a VNF, for processing. The packets are sent using three layers of networking: an underlay physical network, an overlay logical network, and a second overlay logical network.

Abstract: A method for reassigning flows to cores in a multi-core network device includes receiving a packet flow and periodically determining a packet rate of the flow and the processing load on each of the worker cores. Unassigned flows are assigned to the least loaded core. If an assigned flow has a packet rate that exceeds a particular threshold proportion of the processing capacity of the currently assigned worker core, reassigning the flow to the lowest loaded worker core unless the resulting load would exceed the current load on the currently assigned worker core.

The QCI may be used to configure one or more transmission parameters of a device (e.g., a user equipment (UE) or a base station) at a PHY layer. The PHY layer may select the one or more transmission parameters to meet the QoS conditions of a given QoS class of a transport block being communicated. A modulation and coding scheme (MCS) value may be used as the QCI for the PHY layer, a channel quality indicator (CQI) value may be used as the QCI for the PHY layer, or a cell radio network temporary identifier (C-RNTI) may be used as the QCI for the PHY layer. In some cases, the QCI may be a single bit included in a downlink control message.
