A method for a wireless local area network, the method performed by a station includes receiving a beacon frame from an access point (AP), the beacon frame including a Traffic Indication Map (TIM) element indicating that the AP has a buffered frame for the station; transmitting a power save (PS)-poll frame and at least one duplicated PS-poll frame to the AP on a first 20 MHz channel and at least one second 20 MHz channel, the PS poll frame being transmitted on the first 20 MHz channel, the at least one duplicated PS poll frame being transmitted on the at least one second 20 MHz channel; and receiving the buffered frame from the AP as a response of at least one of the PS poll frame and the at least one duplicated PS poll frame.

Aspects of the present disclosure relate to a pre-fetching architecture and scheduler for multi-station APs. An example method generally includes fetching, from a plurality of host buffers, descriptive information for a set of packets based, at least in part, on an amount of descriptive information already cached for transmission to one or more target devices; using the fetched descriptive information to obtain the set of packets; and transmitting the set of packets to the one or more target devices.

An approach, executed by a computer, includes receiving at least an initial polling quantity and an initial polling frequency and polling an endpoint application using the initial polling quantity and the initial polling frequency. The approach includes determining a first number of events not consumed in a queue of a listening application and a second number of events generated at the endpoint application and remaining in a queue at the endpoint application and comparing the number of events in each queue. The approach includes adjusting at least one of the initial polling quantity and the initial polling frequency based, at least in part, on the comparison of the first number of events not consumed in the queue of the listening application and the second number of events generated at the endpoint application and remaining in the queue at the endpoint application.

A network node comprises an optical input, an optical output, a random-access queue and processing system. It receives a data packet, at the optical input and determines whether to process it as a guaranteed-service packet or as a statistically-multiplexed packet. A guaranteed-service packet is output within a predetermined maximum time of receipt, optionally within a data container comprising container control information. A statistically-multiplexed packet is queued. The node determines a set of statistically-multiplexed packets that would fit a gap between two guaranteed-service packets; selects one of the packets; and outputs it between the two guaranteed-service packets.

A method for a wireless local area network. The method according to one embodiment is performed by an access point and includes receiving a power save (PS) poll on a first 20 MHz channel from a station operating in a power save mode; receiving at least one duplicated PS poll frame on at least one second 20 MHz channel from the station, the at least one duplicated PS poll frame including at least one duplicate of the PS poll frame; and transmitting a buffered frame to the station as a response to at least one of the PS poll frame and the at least one duplicated PS poll frame.

Disclosed are various embodiments for rate proportional scheduling to reduce packet loss in virtualized network function chains. A congestion monitor executed by a first virtual machine executed by a host computing device can detect congestion in a receive queue associated with a first virtualized network function implemented by a first virtual machine. The congestion monitor can send a pause signal to a rate controller executed by a second virtual machine executed by the host computing device. The rate controller can receive the pause signal. In response, the rate controller can pause the processing of packets by a second virtualized network function implemented by the second virtual machine to reduce congestion in the receive queue of the first virtualized network function.

The present invention relates to a wireless communication terminal and a wireless communication method for efficiently scheduling uplink multi-user transmission.

To this end, provided are a base wireless communication terminal, including: a transceiver configured to transmit and receive a wireless signal; and a processor configured to control an operation of the transceiver, wherein the processor selects an access category for transmitting a trigger frame which solicits an uplink multi-user transmission, performs a backoff procedure for transmitting the trigger frame based on the selected access category, and transmits the trigger frame when a backoff counter of the backoff procedure expires and a wireless communication method using the same.

An apparatus and a method for transmitting control information in a small base station of a wireless communication system are provided. In the method, when the small base station operates in a Low Duty operation Mode (LDM) in a superframe, a control signal including LDM operation information is generated. Only a subframe via which a preamble, a control signal including the LDM operation information, and a SuperFrame Header (SFH) are transmitted is transmitted during the superframe. When the small base station operates in a normal operation mode in a superframe, at least one of the control information and data is transmitted via at least one subframe of the superframe.

Approaches are described for release-time-driven (RTD) prioritization of on-board content scheduling and delivery to in-transit transport craft via communications systems. In context of a constrained network, content is scheduled to be delivered to those in-transit on-board media servers in a manner driven by respective release times and other prioritization factors associated with the updated content. Each content is associated with a RTD priority profile that can define a release time, a release priority, and a profile plot for the content. The RTD priority profiles can be used to compute priority surfaces that define priority scores over a multidimensional space for a particular time. A subset of the content can be selected for delivery based on the priority surfaces, and can be scheduled for delivery according to network capacity determinations.

A scheduling policy determining method and a related apparatus are disclosed. The method includes: determining, in response to that a first link is congested, a first scheduling policy for traffic of at least one application on the first link according to scheduling policies separately supported by a plurality of applications to which traffic carried on the first link belongs; and applying the first scheduling policy. When the first link is congested, a scheduling policy is determined according to the scheduling policies supported by the plurality of applications on the link, so that a control device or a network device can schedule the traffic of the applications in a coordinated manner according to the scheduling policies separately supported by the applications.
