Abstract: The present disclosure provides communication apparatus and communication method for user-specific persistent allocation. A communication apparatus comprises circuitry which, in operation, generates a transmission signal comprising a common field, a user specific field and a data field, the common field including RU information for each of one or more allocations in the data field and the user specific field including one or more user information, each indicating a user-specific allocation among the one or more allocations in the data field; and a transmitter, which, in operation, transmits the generated transmission signal; wherein the user specific field is free from at least one user information for a persistent allocation containing a recurring transmission among the one or more allocations.

Abstract: The present disclosure provides communication apparatus and communication method for PPDU format identification. The communication apparatus comprising circuitry which, in operation, generates a Physical Layer Protocol Data Unit (PPDU) that contains a first signal field, a second signal field and a third signal field, and wherein the second signal field is used to determine whether a physical layer (PHY) version of the generated PPDU is not older than a defined PHY version, and the third signal field is used to indicate the PHY version of the generated PPDU; and a transmitter which, in operation, transmits the generated PPDU.

Abstract: The present disclosure provides communication apparatus and communication method for channel estimation. The communication apparatus comprises circuitry, which, in operation, generates a signal comprising one or more non-legacy long training field (LTF) symbols, each of the one or more non-legacy LTF symbols comprising a plurality of data tones and a plurality of pilot tones, maps a non-legacy LTF sequence to the plurality of data tones and the plurality of pilot tones, and groups the plurality of data tones with nonzero non-legacy LTF sequence values into a first tone group and a second tone group; and a transmitter which, in operation, transmits the generated signal.
