Abstract: A second apparatus for wireless communication includes: a transceiver; and a processing circuit configured to receive, from a first apparatus via the transceiver, a physical layer protocol data unit (PPDU) including a first signal field having a fixed length and a second signal field having a variable length. The second signal field includes an orthogonal frequency-division multiplexing (OFDM) symbol block including at least one OFDM symbol, and one or more repetitions of the OFDM symbol block.

Abstract: The present disclosure provides a wireless communication method. The wireless communication method includes a first device used to negotiate a buffer size with a second device, provide data including a duration field to the second device, and receive a first block acknowledgement from the second device. The first block acknowledgement may include a first block acknowledgement bitmap. The duration field included in the data from the first device may include an indication of a duration associated with the first block acknowledgment that is less than an upper bound duration associated with a second block acknowledgement that includes a second block acknowledgement bitmap with a maximum length.
