This disclosure describes methods, devices, and systems related to generate a trigger frame including one or more resource block identifications (RBIDs), each RBID being associated with a respective resource unit of one or more resource units on a communication channel; cause to transmit the first trigger frame to each of one or more devices; process a received a power save poll (PS-poll) bit from a first device of the one or more devices on a spatial stream and a first resource unit of the one or more resource units; cause to transmit an acknowledgment to each of the one or more user devices; cause to transmit data buffered in the at least one processor to the first device; and process a received an acknowledgment from the first device confirming receipt of the data.

A method and an apparatus are provided for performing wireless communication between terminals. An inquiry message is transmitted to a neighboring terminal. An inquiry response message is received from the neighboring terminal. It is determined whether the apparatus overlaps the neighboring terminal. When the apparatus overlaps the neighboring terminal, paging is automatically performed, without intervention of a user of the apparatus, and pairing between the apparatus and the neighboring terminal is established.

A system can comprise a memory that is configured to store and retrieve a first signal. The system can further comprise a generator that is configured to generate first in-phase, quadrature sub-carrier values. The system can further comprise a look up table that stores predetermined second in-phase, quadrature sub-carrier values. The system can further comprise a pseudo-random look up table generator that is configured to operate on the predetermined second in-phase, quadrature sub-carrier values to produce a pseudo-random symbol of data values. The system can further comprise a component that is configured to time align, buffer, and inject a second signal into a radio used by the system, wherein the second signal is selected from the memory, the generator, the look up table, and the pseudo-random look up table generator.

A system and a method for communicating through a plasma sheath formed on a vehicle, include a matching layer disposed on at least a portion of a communication device of the vehicle. The matching layer is configured to generate a resonant frequency in relation to the plasma sheath. A modulator is configured to generate one or more electromagnetic waves that modulate the resonant frequency.
