Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiplexing clients of different generations in trigger-based transmissions, including trigger-based transmissions in extremely-high throughput (EHT) Wi-Fi systems. An access point (AP) may generate a trigger frame compatible with two types of stations (STAs), such as EHT STAs and legacy (or high efficiency (HE)) STAs. The AP may transmit the trigger frame to a group of STAs, where legacy STAs may process the trigger frame a legacy trigger frame. EHT STAs may process the trigger frame to determine resource unit (RU) allocations for uplink transmissions in a bandwidth greater than a legacy bandwidth. An EHT STA may determine the resources in the larger bandwidth based on an EHT RU allocation table, a legacy RU allocation table and an additional bit in the trigger frame, or an ordering of RU allocations in the trigger frame.

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: A method of wirelessly communicating a packet includes generating, at a first wireless device, a first packet including a first preamble decodable by a plurality of devices and a second preamble decodable by only a subset of the plurality of devices. The first preamble includes a first signal field. The second preamble includes a first training field. The method further includes transmitting the first packet concurrently with one or more second packets to be transmitted by wireless devices other than the first wireless device.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the apparatus may determine whether to transmit a frame with CSDs based on a number of antennas, a number of streams, or both. In another aspect, the apparatus may determine a first set of CSD values for transmitting a first set of information associated with a first portion of the frame. In a further aspect, the apparatus may determine a second set of CSD values for transmitting a second set of information associated with a second portion of the frame. In yet another aspect, the apparatus may transmit the first set of information based on the first set of CSD values and the second set of information based on the second set of CSD values using the number of antennas, the number of streams, or both.

Abstract: Apparatuses for wireless communication are provided. The apparatus includes a processor configured to generate a packet for transmission via a wireless signal. The packet is generated for transmission over a bandwidth of 1 MHz using at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising 32 subcarriers described by indices from -16 to 15, wherein each of the 32 subcarriers has an average constellaton enrgy. The apparatus further includes a transmitter configured to transmit the packet via the wireless signal such that each average constellation energy for subcarries having indices of -8 to -1 and 1 to 8 deviates no more than +-4 dB from an overall average of the average constellation energies over subcarriers having indices of -8 to -1 and 1 to 8, and each average constellation energy for subcarries having indices of -13 to -9 and 9 to 13 deviates no more than +4/-6 dB from the overall average.

Abstract: Methods and apparatuses for communicating over a wireless communication network are disclosed herein. One example apparatus includes a memory that stores instructions. The apparatus further includes a processor coupled with the memory. The processor and the memory are configured to determine a total bandwidth for a transmission of a message, the total bandwidth including a plurality of tones. The processor is further configured to divide the plurality of tones in the total bandwidth into one or more 26-, 52-, 106-, 242-, or 996-tone blocks. The processor is further configured to determine an indication. The indication assigns one or more of the one or more tone blocks to a first wireless communication device. The apparatus further includes a transmitter configured to transmit the indication to at least the first wireless communication device or a second device.
