In some aspects, the disclosure is directed to methods and systems for signaling and decoding of punctured sub-bands in a trigger-based PPDU. In one aspect, at least one of the communication interface or the processing circuitry of a wireless communication device is configured to generate a trigger frame that includes signaling indicating that at least one other wireless communication device is allowed to reduce a bandwidth of an allocated resource unit (RU) for transmitting data via a communication channel; transmit, via the communication channel, the trigger frame to at least one other wireless communication device; receive, via the communication channel and from the at least one other wireless communication device, an uplink (UL) orthogonal frequency division multiple access (OFDMA) frame including the data; and process the UL OFDMA frame including the data based on the signaling.

In some aspects, the disclosure is directed to methods and systems for utilizing protocols to enable two 802.11 devices to exchange their dynamically-changing local channel availability table and form a mutual channel availability table with time, frequency, and transmission rate domains available. This table may be used to make optimum opportunistic use of link resources by adapting packet duration, frequency utilization and transmission rate to channel conditions.
