Abstract: A first communication device generates a null data packet (NDP) announcement (NDPA) frame to announce a subsequent transmission of one or more NDPs to one or more second communication devices as part of a ranging measurement procedure. The NDPA frame is generated to include a training signal repetition field that specifies a number of instances of a training signal to be included in the one or more NDPs. The first communication device transmits the NDPA frame as part of the ranging measurement procedure. The first communication device generates at least one NDP to include a number of instances of the training signal that equals the number of instances of the training signal indicated by the training signal repetition field in the NDPA, and after transmitting the NDPA frame, transmits the at least one NDP as part of the ranging measurement procedure.

Abstract: A first communication device receives one or more physical layer (PHY) data units, which include a plurality of media access control (MAC) layer data units, from a second communication device via a communication channel that includes a first frequency segment and a second frequency segment separated by a gap in frequency, including simultaneously i) receiving a first MAC layer data unit via the first frequency segment of the communication channel, and ii) receiving a second MAC layer data unit via the second frequency segment of the communication channel. The first communication device generates acknowledgement information for the plurality of MAC layer data units, and transmits the acknowledgment information to the second communication device via one or both of i) the first frequency segment and ii) the second frequency segment.

Abstract: A controller (56), for use in a storage device (44, 114) of a data processing system (20, 90), includes a host interface (68), a memory interface (60) and one or more processors (64). The host interface is configured to communicate over a computer network (28, 98) with one or more remote hosts (24, 102) of a data processing system. The memory interface is configured to communicate locally with a non-volatile memory (52) of the storage device. The one or more processors are configured to manage local storage or retrieval of media objects (80) at the non- volatile memory, and to selectively compute metadata (84) that defines content characteristics of media objects that are stored, or that are to be stored, in the non-volatile memory.

Abstract: A first communication device generates a first portion and a second portion of a wakeup radio (WUR) wakeup packet. The first portion of the WUR wakeup packet corresponds to a wireless local area network (WLAN) legacy preamble, and spans a first frequency bandwidth. The second portion of the WUR wakeup packet spans a second bandwidth that is less than the first bandwidth, and is configured to cause a WUR of a second communication device to cause a WLAN network interface device of the second communication device to transition from a low power state to the active state. Generating the second portion of the WUR wakeup packet includes i) generating a sync portion having a plurality of sync symbols, and ii) generating a wakeup packet body. The first communication device transmits the WUR wakeup packet.

Abstract: A media content converter (20), for converting media content into network packets, includes logic circuitry, a header generator (76) and a multiplexer (80). The logic circuitry is configured to partition the media content into payloads for the network packets. The header generator is configured to generate packet headers for the network packets, by populating with data a plurality of header fields according to a predefined header format. The multiplexer is configured to stream a sequence of the network packets for transmission over a communication network, by combining the generated packet headers from the header generator with the corresponding payloads from the logic circuitry.

Abstract: A first communication device generates a block acknowledgement (BA) frame that includes (i) acknowledgement information to indicate, to a second communication device, whether the first communication device successfully received multiple media access control (MAC) frames transmitted by the second communication device, and (ii) an indication of a change in a BA session between the first communication device and the second communication device. The first communication device transmits the BA frame to the second communication device, where the BA frame causes the second communication device to adopt the change in the BA session in response to receiving the BA frame.

Abstract: A communication device sets a first channel access timer to a first duration in which at least a first portion of a communication channel is expected to be busy, the first timer corresponding to a first one of a plurality of component channels of the communication channel. The communication device also sets a second channel access timer to a second duration in which at least a second portion of the communication channel is expected to be busy, the second timer corresponding to a second one of the plurality of component channels. The communication device counts down the first timer and the second timer. When at least one of the first timer and the second timer reaches zero, the communication device determines whether one or more of the component channels are idle, and transmits at least one signal in at least one of the component channels determined to be idle.

Abstract: Embodiments described herein provide a method for fragmenting and reassembling data frames on a medium access control (MAC) layer in a wireless local area network. A datagram is received from an application running on a first network device, for transmission over a wireless communication link in the wireless local area network. A negotiation request is initiated with a second network device for determining whether both the first network device and the second network device have enhanced directional multi-gigabit capability (EMDG) for data segmentation and reassembly. When both devices have EMDG capability and the size of the datagram exceeds the maximum size defined by the wireless local area network transmission protocol, the datagram is segmented into a plurality of transmission data units on the MAC layer.
