Control information update for dynamic time-division duplexing (tdd)

Abstract

Wireless communications systems and methods related to updating control information based on medium sensing are provided. A first wireless communication device communicates with a second wireless communication device, a first transmission grant for a transmission opportunity (TXOP) in a frequency band. The first wireless communication device performs medium sensing for the TXOP. The performing the medium sensing includes detecting a reservation signal for the TXOP. The first wireless communication device transmits, to the second wireless communication device, an updated transmission grant for the TXOP based on at least the first transmission grant and the medium sensing. The first wireless communication device transmits, to the second wireless communication device in the frequency band, data during the TXOP based on the updated transmission grant.
