Abstract: In an embodiment, application delivery to end-user devices may be handled by a combination of an application device and a distributed set of split edge devices located closer to the end-user device within a network. The split edge devices are instructed by the application device about how to manage traffic to and from the end-user devices. The application device determines whether content is stored to content cache of a split edge device. The application device, when the content is stored to the split edge device, refrains from sending the content and instead sends instructions to the split edge device that include reference to a location of the content, and instruct the split edge device to send the content to an application and/or device. The application device, when the content is not stored to the split edge device, sends the content with instructions to store the content locally.

The technique further includes generating and transmitting information in one or more frames that directs wireless communications based on the wireless resource allocations.

Abstract: A first network device including first and second transceiver modules. The first transceiver module: during a first downlink period, transmits an uplink indication (UI) signal; and during an uplink period and subsequent to transmitting the UI signal, transmits a first data signal. The UI signal indicates when the first data signal is transmitted. The second transceiver module, prior to transmission of the UI signal, transmits a notice signal that indicates to a second network device not to transmit data to the second transceiver module during a second downlink period. The second downlink period is subsequent to an unused portion of the uplink period. The second transceiver module: transitions to a power save mode prior to transmission of the first data signal; and transmits a second data signal from the first network device based on the UI signal, subsequent to transmission of the first data signal, and during the unused portion.

Abstract: A network interface device generates a packet that includes a beacon frame for transmission in a superframe. The beacon frame is used to announce the presence of a network and also is formatted as a beamforming training (BFT) frame to permit other communication devices to perform beamforming training with the packet. The beacon frame is generated to include (i) a frame control field, (ii) a duration field, (iii) a timestamp field, (iv) information indicative of a time of a subsequent association beamforming training (A-BFT) time slot, and (v) beamforming training information, which includes a countdown field. The network interface device transmits the packet during a beacon timeslot of the superframe, which is separate from an association beamforming training (A-BFT) timeslot of the superframe.

Abstract: In a method for transmitting a data unit in a wireless communication network, a physical layer (PHY) preamble and a media access control layer (MAC) header are generated. In generating the MAC header, a first address field to include a first address and a second address field to include a second address are generated. The first, not globally unique, address indicates a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The second address field indicates the other one of a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The first address field and the second address field are included in the MAC header. The MAC header omits a globally unique address corresponding to the first address of the first address field.

Abstract: A first communication device transmits one or more first communication frames during a transmit opportunity period (TXOP) of the first communication device via a first composite channel. A control frame is generated, wherein the control frame includes information indicating a bandwidth of the first composite channel. After the one or more first communication frames have been transmitted, the first communication device transmits, during the TXOP, the control frame via the first composite channel. Information from a response frame that indicates a bandwidth of a second composite communication channel is extracted, the response frame having been transmitted by a second communication device and received by the first communication device during the TXOP. The first communication device transmits one or more second communication frames during the TXOP, wherein the one or more communication frames span the second composite communication channel and do not span the entire first composite communication channel.

Abstract: A desired number of buffers to be used in a block acknowledgment (BA) session or with media access control (MAC) data units having a same traffic identifier (TID) is determined. A desired maximum MAC data unit size to be used in the BA session or with the MAC data units having the same TID is determined.

An indication of the desired maximum MAC data unit size to be used in the BA session or with the MAC data units having the same TID is transmitted to the second communication device for negotiating with the other station.
