Abstract:
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a hybrid automatic repeat request (HARQ) protocol in a wireless local area network (WLAN). In some aspects, a first WLAN device may transmit a first HARQ frame to a second WLAN device. The first WLAN device may receive a first feedback message from the second WLAN device. The first feedback message may be a HARQ Block Acknowledgement (H-BA) message. The first WLAN device may determine to enable the HARQ protocol based on the first feedback message. The first WLAN device may receive an indication of an amount of memory available at the second WLAN device for processing HARQ transmissions. The first WLAN device may transmit a second HARQ frame to the second WLAN device based, at least in part, on the amount of memory available at the second WLAN device for processing HARQ transmissions.
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.

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.

In one example, a system and method includes transmitting a first type of information from a transmitter at a first set of transmission parameters, wherein the first set of transmission parameters includes a first PHY data rate and a first transmission power, transmitting a second type of information at a second set of transmission parameters, wherein the second set of transmission parameters includes a second PHY data rate and a second transmission power, and switching between the first set of transmission parameters and the second set of transmission parameters as a function of the type of information to be transmitted. One or more of the first PHY data rate and the first transmission power are different than the second PHY data rate and the second transmission power, respectively.

In this example, each respective command frame of the plurality of command frames includes: an identification of at least one graphical command corresponding to the at least one token, and one or more arguments associated with the at least one token. In this example, the method also includes outputting, by the source device and for transmission to a sink device, the plurality of command frames.
