Abstract: This disclosure provides methods, devices and systems for configuring tones for a distributed resource unit (RU) across a channel bandwidth to improve frequency diversity and available transmit power. A distributed RU may include a set of tones that may be allocated across a bandwidth that is greater than a bandwidth of the aggregate quantity of tones. The set of tones may include a set of data tones grouped into contiguous groups of one or more data tones and a set of non-contiguous pilot tones. The data tones may be mapped to useful tones over a center portion of a half-bandwidth of the channel. The pilot tones may be mapped near edge tones at edges of the channel bandwidth or near direct current tones at a center of the channel bandwidth. A system bandwidth may include one or more channel bandwidths associated with distributed RUs.

Abstract: This disclosure provides methods, devices and systems for soliciting trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data units (PPDUs). Some implementations more specifically relate to trigger frame designs that support non-legacy TB PPDU formats. In some aspects, a trigger frame may carry information to be included in a physical layer (PHY) preamble of a TB PPDU solicited by the trigger frame. For example, the information may indicate values of one or more subfields of a universal signal field (U-SIG) associated with the non-legacy TB PPDU format. In some aspects, the information may be carried in a special user information field of the trigger frame. For example, the special user information field may be identified by a special association identifier (AID) value. The special AID value may be different than any AID values assigned to wireless communication devices in a basic service set (BSS) associated with the TB PPDU.

Abstract: This disclosure provides methods, devices and systems for generating a secure long training field (LTF). In some implementations, the secure LTF may include a randomized bit sequence that is difficult, if not impossible, to replicate by any device other than the transmitting device and the intended receiving device. For example, the transmitting device may use a block cipher or stream cipher to generate a pseudorandom bit sequence and may select a subset of bits of the pseudorandom bit sequence to be mapped to a sequence of modulation symbols representing an LTF symbol of the secure LTF. More specifically, each of the modulation symbols is mapped to a respective one of a number of subcarriers spanning a bandwidth of the secure LTF. The transmitting device may further transmit a physical layer convergence protocol (PLCP) protocol data unit (PPDU) that includes the secure LTF to the receiving device.

Abstract: Described herein are techniques in which a computer system guides a group of participants through a session (e.g., a learning session) in real time. The techniques remove a need for a leader (e.g., a course instructor) to be present in order to guide the participants (e.g., students) through the session. The techniques allow each participant to join a session using a respective computing device, and interact with shared content through one or more graphical user interfaces (GUIs). The techniques implement the shared content as a sequence of states (e.g., steps), and guide the participants through the sequence of states. The techniques allow the computer system to replace a human in guiding users through a session (e.g., a learning session). By removing the need for human guidance through a session, the techniques exponentially increase the scale at which educational experiences (e.g., for a remote learning session) can be distributed and used.
