Abstract: Timer management techniques are described. An example processing device includes a memory configured to store successive wheels available to be included in traversal paths for timers running on the device, each wheel representing a queue of timers, each wheel having a different, corresponding time delay (TO) value for queuing a timer, and processing circuitry in communication with the memory. The processing circuitry is configured to determine, in response to a request for a timer, a total traversal time for the timer, to select, from the stored wheels, a subset of wheels such that a sum of the respective TO values of the selected subset is within a predetermined margin of error with respect to the total traversal time for the timer, and to sequence the selected subset of wheels based on the respective TO values of the selected subset of wheels to form a traversal path for the timer.

Abstract: A wireless transmit/receive unit (WTRU) may receive a plurality of transport blocks over a plurality of configured carriers. The WTRU may generate hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for the plurality of transport blocks, channel state information (CSI) feedback for at least one of the plurality of configured carriers, and a cyclic redundancy check (CRC). Further, the WTRU may generate a feedback message that includes a number of HARQ-ACK feedback bits for the HARQ-ACK feedback, a number of CSI feedback bits for the CSI feedback, and a number of CRC bits for the CRC. The WTRU may then determine a power to be used for a Physical Uplink Control Channel (PUCCH) transmission based on the number of HARQ-ACK feedback bits, the number of CSI feedback bits, and the number of CRC bits. Moreover, the WTRU may transmit the feedback message in the PUCCH transmission at the determined power.

Abstract: Described herein are systems, methods, and software to enhance flow operations on a host computing system. In one implementation, a virtual switch on a host identifies a packet from a virtual node. In response to identifying the packet, the virtual switch determines whether the packet corresponds to a cached result action based on traits of the packet. If the packet corresponds to a cached result action, then the virtual switch may process the packet in accordance with the cached result action. In contrast, if the packet does not correspond to a cached result action, then the virtual switch may process the packet in accordance with first flow operations to determine a result action, and cache the result action for use with future packets.

Abstract: In one embodiment, nodes use in-band operations data (e.g., carried in iOAM data field(s)) to signal departures in the processing of a packet in a network. A “departure” refers to a divergence or deviation, as from an established rule, plan, or procedure. Departures include, but are not limited to, sending a packet over a backup path (thus, a departure/deviation from sending over a primary path); offload processing of a packet (thus, a departure/deviation from processing of a packet by an application processing apparatus); and exception or punting/slow/software path processing of a packet (thus, a departure/deviation from normal or fast/hardware path processing of a packet). In one embodiment, a proof of transit validation apparatus uses departure information to select among multiple possible verification secrets, with the selected verification secret used in validation processing with a cumulative secret value obtained from the packet.

Abstract: A Road Side Unit (RSU) (120) transmits V2X report information to a control node (140) and transmits location-related information about the RSU (120) to the control node (140). The control node (140) determines, based on the received location-related information about the RSU (120), at least one of: one or more sending nodes; a transmission area; a distribution path; and a communication scheme, to distribute a V2X control message to a plurality of UEs. It is thus, for example, possible to contribute to achievement of a configuration in which, upon receiving V2X report information from an RSU, a server transmits a V2X control message based on the V2X report information to a plurality of vehicles or pedestrians.

Abstract: A wireless access point (WAP) determines whether to switch from one or more first communication channels to one or more second communication channels when the one or more first communication channels are experiencing congestion. The WAP determines an amount of congestion the one or more first communication channels are experiencing. When the one or more first communication channels are experiencing congestion, the WAP determines whether one or more communication devices can support, or reliably support, a channel switching announcement signal using the one or more first communication channels. If a sufficient number of communication devices from among the one or more communication devices can support, or reliably support, the channel switching announcement signal, the WAP broadcasts the channel switching announcement signal to the one or more communication devices to announce its intention to switch from the one or more first communication channels to the one or more second communication channels.

Abstract: Distributed computing systems, devices, and associated methods of packet routing are disclosed herein. In one embodiment, a method includes receiving, from a computing network, a packet at a packet processor of a server. The method also includes matching the received packet with a flow in a flow table contained in the packet processor and determining whether the action indicates that the received packet is to be forwarded to a NIC buffer in the outbound processing path of the packet processor instead of the NIC. The method further includes in response to determining that the action indicates that the received packet is to be forwarded to the NIC buffer, forwarding the received packet to the NIC buffer and processing the packet in the NIC buffer to forward the packet to the computer network without exposing the packet to the main processor.

Abstract: The described technology is generally directed towards a network node in a radio communications system adaptively switching the modulation and coding scheme (MCS) table in use by user equipment. The network node evaluates performance data corresponding to one or more performance criteria to determine which MCS table to use. Non-limiting examples of performance data/performance criterion include the current transmission scheme, user equipment cell location, user equipment geometry, the number of transmit and/or receive antennas, the feedback reporting mode, the frequency band used in communications, network node performance, base station transmission power, user equipment deployment scenario, user equipment radio environment, user equipment recommendation, and the type of service being served by the base station. Any of the above performance data/performance criteria can be combined to adaptively make a determination and selection of which modulation and coding scheme table to use.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems support beamforming to improve the reliability of transmissions from a transmitting device to a receiving device. In some cases, a wireless device broadcasts information using beamforming. In such cases, in order to limit the overhead and power consumption associated with the broadcast, the wireless device utilizes the techniques described herein for broadcasting information using beamforming. In particular, rather than broadcasting large amounts of data in a beam-sweep, a wireless device broadcasts a relatively lightweight signal in a beam-sweep to first identify a receiving device and/or a suitable beam for communicating with a receiving device. Once the transmitting device identifies the receiving device and/or the suitable beam, the transmitting device broadcasts the data to be received by the receiving device.

Abstract: Managing connections to be established between clients and access points for the purposes of accessing wireless services is contemplated. The connections may be managed according to a predictive load balancing strategy where connections may be established and adjusted in anticipation of predicted client demands, such as to achieve an optimized throughput.

Abstract: Operations include determining billing for data being transmitted out of an Autonomous System (AS). An internal node in the AS determines billing for a packet transmitted out of the AS based at least on an egress path of the packet. The packet is received at the internal node in the AS The internal node selects an egress path of the packet based on one or more characteristics of the packet. The egress path is mapped directly or indirectly to a billing counter. The billing counter is incremented based on (a) the transmission of the packet on the overlay network to the egress gateway and (b) transmission of the packet out of the AS on the selected egress path.
