16. A method for wireless communication, comprising:
receiving, by a wireless device, a frame from an access point over a wireless network;
decoding, by the wireless device, the frame to determine resource units unavailable for transmission during a transmission opportunity, and to identify one or more maximal transmission parameter values for use of the determined resource units, wherein decoding the frame to identify the one or more maximal transmission parameter values comprises:
decoding, by the wireless device, the frame to determine a duration of the transmission opportunity and a received signal strength (RSSI) limit for use of the determined resource units during the transmission opportunity, the RSSI limit determined based at least in part on decoded contents of one or more fields of the received frame;
determining whether or not an RSSI for receiving the frame is below the RSSI limit; and
indicating, based on the determination that the resource units are unavailable for transmission during the transmission opportunity, that the resource units are available for use by one or more other devices; and
transmitting, by the wireless device, data to a second wireless device using at least a portion of the determined resource units in response to determining that the transmitting is in accordance with the one or more maximal transmission parameter values, wherein transmitting the data is in response to the RSSI for receiving the frame being below the RSSI limit.
