Abstract: When a communication device determines that a packet (PPDU) is to use a first length of a training field and a first duration of a guard interval (GI), the communication device generates a field of the PHY preamble to include a subfield set to a first value that indicates the packet uses the first length of the training field and the first duration of the GI. When the communication device determines that the PPDU is to use the first length of the training field and a second duration of the GI the communication device generates the field of the PHY preamble to include i) the subfield set to the first value, ii) one or more other subfields set to one or more second values that correspond to a mode that is not permitted by a communication protocol, to indicate that the PPDU uses the first length of the training field and the second duration of the GI.

Abstract: A network device is described. The network device includes a plurality of ingress interfaces, a plurality of memory units configured to store packets received at the plurality of ingress interfaces, a first pool of memory access tokens, and one or more integrated circuits that implement a memory controller. The memory access tokens correspond to respective memory units and are distinct within the first pool. The memory controller is configured to selectively assign at least one individual memory access token to the ingress interfaces to govern write access to the memory units. The ingress interfaces write packets to memory units identified by the corresponding assigned memory access tokens. The network controller is configured to reassign a first memory access token from a first ingress interface to a second ingress interface between consecutive write commands from the first ingress interface based on a write access scheme to access non- sequential memory units.

Abstract: A first communication device receives a plurality of training signals from a second communication device via a communication channel. The first communication device determines, based on the plurality of training signals, a channel matrix corresponding to the communication channel, and determines, based the channel matrix and without decomposing a steering matrix, compressed feedback to be provided to the second communication device. The first communication device transmits the compressed feedback to the second communication device to enable the second communication device to steer at least one subsequent transmission to the first communication device.

Abstract: Embodiments described herein provide a method for transmitting a wake-up radio signal to low power devices in a wireless local area network. Data for transmission to a wireless device is received at a wireless access point, and a wake-up radio packet is generated. The wake-up signal includes a first preamble, a second preamble, and payload data including a wake-up user identifier assigned to the wireless device. The wake-up radio packet is encoded into an encoded wake-up radio frame including a plurality of encoded data symbols representing modulated payload data. The encoded wake-up radio frame is modulated onto a modulated waveform for transmission. A signal corresponding to the modulated waveform is transmitted to the wireless device.

Abstract: Packet data corresponding to a multicast (MC) packet received by a network device is stored in a packet memory. A header of the MC packet is analyzed to determine two or more ports via which the MC packet is to be transmitted. It is determined that two or more pending read requests are to read packet data from a particular memory location in the packet memory. In response to determining that the two or more pending read requests are to read packet data from the particular memory location, the packet data is read a single time from the particular memory location. Respective instances of the packet data read from the particular memory location are provided to respective two or more read client devices for subsequent transmission of the packet data via the two or more ports determined by the packet processor.

Abstract: Embodiments described herein provide a method for performing multi-level coding in a discrete multitone modulation (DMT) communication system. A plurality of data bits are divided into a first number of un-encoded bits and a set of bits to be encoded. The set of bits to be encoded are encoded into a second number of encoded bits. The first number is different from the second number, and the first number is an even number or an odd number. The first number of un-encoded bits and the second number of encoded bits are mapped into a plurality of constellation points. The plurality of constellation points are transmitted as orthogonal frequency-division multiplexing (OFDM) symbols.

Abstract: Embodiments described herein provide a method for resource unit signaling with reduced data bits in a wireless local area network. At a wireless transceiver, a data frame may be obtained for transmission. The data frame includes a first preamble portion and a second preamble portion compliant with a wireless local area network communication protocol. When an available resource unit for transmitting the data frame is less than an allowed bandwidth, the first preamble portion and the second preamble portion may be configured with resource unit signaling bits. When the available resource unit is greater than or equal to the allowed bandwidth, the resource unit may be virtually divided into a plurality of channels. At least one of the first preamble portion and the second preamble portion may be configured with a first number of bits representing a number of users spatially multiplexed on a channel from the plurality of channels.
