    Abstract: Methods and apparatuses are disclosed for communicating over a wireless communication network. In one aspect, an apparatus can include a memory that stores instructions, a processor, and a segment parser. The memory can be configured to store instructions. The processing system is configured to execute the instructions to generate a message according to a tone plan for transmission to one or more destination devices within one of a 240 or 320 MHz total channel bandwidth. The processing system is further configured to provide the message for transmission over the 240 or 320 MHz total channel bandwidth, where the message is encoded for transmission by at least one of a binary convolutional coded (BCC) interleaver or a low density parity check (LDDC) tone mapper. The segment parser is configured to segment the total channel bandwidth into a plurality of segments of equal or unequal sub-band bandwidths or number of data tones.

    Abstract: This disclosure provides systems, methods and apparatuses for indicating a data rate of a packet. The transmitting device may select the data rate of a data field of the packet to be transmitted to the receiving device, and may select a pattern to embed within a preamble of the packet based on the selected data rate. In some implementations, the transmitting device may select a first structure including a first number of instances of a sequence or its logical complement if the selected data rate is a low data rate, and may select a second structure including a second number of instances of the sequence or its logical complement if the selected data rate is a high data rate.

    Abstract: This disclosure provides systems, methods and apparatuses for wireless communications. In some implementations, a first access point (AP) may identify other APs to participate in a coordinated access point transmission session, may obtain a transmit opportunity (TXOP) for transmitting wireless signals over a frequency bandwidth, may allocate corresponding portions of the frequency bandwidth to the identified APs for downlink (DL) transmissions during the TXOP, may select a duration of the TXOP for the coordinated access point transmission session based at least in part on an amount or percentage of the first AP's frequency bandwidth that is allocated to the one or more identified APs for the coordinated access point transmission session, and may output information indicative of at least one of the selected TXOP duration or the corresponding portions of the frequency bandwidth allocated to the respective identified AP by the first AP.

    Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an access point (AP), that reduce the overhead associated with triggering an uplink transmission from the wireless station (STA). Features of the present disclosure achieve this by, for example, utilizing a single per-user information field of the trigger to signal a plurality of random access resource units that may be allocated to the one or more STAs in the network. Such a technique is an improvement over the conventional system that require each random access resource unit to be signaled separately in a separate per-user information field (thus increasing the overhead). Additionally, aspects of the present disclosure allow the AP to effectively signal to the STA whether the one or more resources allocated to the at least one STA are a single user resource unit allocation or a multi-user resource unit allocation.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a transmission mode for transmission of an input signal to be transmitted. The input signal may thus be modulated according to the identified transmission mode, and the modulated signal may then be transmitted at some power level to produce a transmitted signal having a spectral envelope. In some cases, the spectral envelope may be defined in terms of a power spectral density (PSD) of the transmitted waveform. The PSD may generally define the power of the waveform signal distributed over frequencies of the waveform. Further, the wireless device may control the modulation of the input signal, in addition to the power level of the input signal, to maintain the spectral envelope to be within a spectral mask defined for the implemented transmission mode as well as to conform to spectral flatness parameters.

    Abstract: Various aspects of the present disclosure provide for an apparatus configured for determining priority information associated with data traffic at an upper layer, mapping the data traffic to a queue at an intermediate layer based on the priority information determined at the upper layer, and mapping an endpoint associated with the queue to an access category (AC) at a lower layer based on the priority information determined at the upper layer. The priority information of the data traffic may be associated with a classification or type of data in the data traffic. The upper layer may be an application layer. The intermediate layer may be a protocol adaptation layer (PAL). The lower layer may be a media access control (MAC) layer. Various apparatuses, methods, computer-readable medium including similar features are also provided herein. Additional and alternative aspects, embodiments, and features are also provided herein.
