Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may configure a preamble for a wireless transmission to include information indicative of a corresponding extremely high throughput (EHT) packet. In some cases, the preamble may be configured to include a signaling field indicative of the EHT packet. In some cases, symbols or bits of the preamble may be configured to indicate the EHT packet. In yet other cases, a field of the packet may be masked to indicate the EHT packet. A wireless station (STA) may receive the configured preamble, and based on the preamble, may receive (e.g., decode) the EHT packet.

Abstract: A method of wirelessly communicating a packet can include generating, at a wireless device, a packet including a plurality of symbols. The method further includes segmenting an input bit vector into a plurality of symbol vectors according to one of a sequential or distributed segmentation procedure. The method further includes splitting each of the plurality of symbol vectors into two or more split vectors according to one of a sequential or round-robin split procedure. The method further includes mapping each of the split vectors into the plurality of symbols according to one of a block-level repetition or a symbol-level repetition. The method further includes transmitting the packet.

Abstract: Methods and apparatus for communicating over a wireless communication network are disclosed herein. One method includes determining a total bandwidth for a transmission of a message according to a first specification, the total bandwidth including a plurality of tones, wherein a portion of the total bandwidth is occupied by a transmission according to a second specification different from the first specification. The method further includes logically dividing a plurality of useable tones into a plurality of resource units and determining an indication, the indication assigning and channel bonding at least two of the plurality of resource units to a wireless communication device of a plurality of wireless communication devices, wherein the indication does not assign the portion of the total bandwidth that is occupied by the transmission according to the second specification.

Abstract: Methods and apparatuses for providing wireless messages can include, for example, an apparatus configured to provide wireless communication. The apparatus includes a memory that stores instructions and a processor coupled with the memory and configured to execute the instructions to select a dual sub-carrier modulation (DCM) mode or a non-DCM mode. The processor is further configured to select one or more interleaver parameters based on the selection of the DCM mode or the non-DCM mode. The processor is further configured to select a first set of interleaver parameters when the DCM mode is selected and a second set of interleaver parameters, different than the first set of interleaver parameters, when the non-DCM mode is selected. The processor is further configured to apply the one or more interleaver parameters to interleave data of a message. The processor is further configured to provide the message for transmission to a receiving device.

Abstract: Methods and apparatus for providing wireless messages according to various tone plans can include a method of wireless communication. The method includes allocating a first allocation unit associated with a first tone plan having a first number of tones, for communication of one or more wireless messages by a wireless device. The method further includes allocating a second allocation unit, associated with a second tone plan having a second number of tones different from the first number of tones, for communication of one or more wireless messages by the wireless device. The method further includes selecting a combined tone plan for the wireless device based on at least the first tone plan and the second tone plan. The method further includes providing a wireless message for transmission by the wireless device according to the combined tone plan.
