Abstract: A method of wirelessly communicating includes generating, at a wireless device, a packet including a first preamble field. The method further includes generating a first repeated preamble field by multiplying the first preamble field by a first frequency-domain polarity sequence. The method further includes transmitting the packet from the wireless device. The packet includes the first preamble field and the first repeated preamble field.

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: Method and systems are disclosed for qualifying a wireless device as frequency hopping device. In some aspects, an access point (AP) may determine a frequency hopping pattern for the wireless device, and then allocate a sequence of unique resource units to the wireless device based on the frequency hopping pattern. Each of the unique resource units include a different set of frequency subcarriers. The AP may receive a series of uplink orthogonal frequency-division multiple access (OFDMA) transmissions from the wireless device on the allocated sequence of unique resource units.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for wireless communication with partial channel puncturing. Using partial channel puncturing, a wireless local area network (WLAN) device may modulate data on a first portion of a wireless channel while refraining from modulating data on a second portion of the wireless channel. The partial channel puncturing can be used with an exclusion bandwidth zone defined for the WLAN. The exclusion bandwidth zone prevents transmissions on portions of channels so that the WLAN transmissions do not interfere with an incumbent system transmission in the exclusion bandwidth zone.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for managing high volumes of space-time-streams in Wi-Fi systems. An access point (AP) may transmit packets including long training field (LTF) sections using a number of space-time-streams greater than eight. Mobile stations (STAs) in the system may or may not be capable of processing this number of streams. The AP may modulate an LTF section using a matrix with dimensions smaller than the number of streams by using tone-interleaving or by performing modulation with separate matrices in time and frequency. In some other implementations, the AP may split the antennas for transmission into groups, each group transmitting either different packets in a subset of streams or a same packet in a subset of tones. In further implementations, the AP may combine multiple space-time-streams into a super stream that supports reception at different types of STAs.

Abstract: One aspect includes a method of establishing, via a first access point, a distributed MIMO joint transmission opportunity with one or more second access points to one or more stations. The method comprises generating, via a processor, a first message for transmission to the stations and the second access points. The first message indicates a null data packet transmission and the stations configured to receive a stream during the joint transmission opportunity. The method also comprises transmitting the first message to the second access points and the stations. The method further comprises generating, via the processor, a reference phase signal for transmission to the second access points.

Abstract: Methods, apparatuses, and computer readable media for resource allocation signaling in a high efficiency wireless local area network (WLAN) are disclosed. A transmitter may generate an indication that a first channel of a plurality of channels associated with a transmission frame has been punctured, the transmission frame including a WLAN signaling field. The transmitter may identify information associated with the WLAN signaling field corresponding to the punctured first channel. The transmitter may transmit the information associated with the WLAN signaling field in a second channel of the plurality of channels. The transmitter may transmit the indication that the first channel has been punctured in the second channel or in a second WLAN signaling field of the transmission frame.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to Wi-Fi systems including frame extensions in transmission frames. Lengths of frame extensions may be determined based on transmission bandwidths and transmission data rates of the frames. Lengths of frame extensions may also be determined based on an amount of useful data in a final symbol of the frame. An access point (AP) may determine frame extension lengths for use in transmitting to stations (STAs) based on reception capabilities of the STAs. An AP may determine frame extension lengths for STAs to use in transmitting frames.
