Methods and apparatus for supporting wireless medium sharing

A first wireless station comprising:

• a wireless transmitter;
• a wireless receiver;
• memory;
• and
• a processor configured to control the first wireless station, during a first time period, to:
• select, based on an amount of data to be transmitted by the first wireless station during a first trigger based frame, a subset of resource units in said first trigger based frame to be used exclusively by the first wireless station;
• designate one or more subsets of resource units in said first trigger based frame to be shared, each of said designated subsets of resource units being a set of shared resource units;
• and
• transmit a first trigger frame including a type indicator indicating that the first trigger frame is a shared transmission type of trigger frame and information identifying the designated one or more resource units in said first trigger based frame to be shared, said one or more resource units to be shared being shared resource units.

A non-transitory computer readable medium including computer executable instructions which when executed by a processor of a first wireless station control the first wireless station, during a first time period, to perform the steps of:

• selecting, based on an amount of data to be transmitted by the first wireless station during a first trigger based frame, a subset of resource units in said first trigger based frame to be used exclusively by the first wireless station;
• designating one or more subsets of resource units in said first trigger based frame to be shared, each of said designated subsets of resource units being a set of shared resource units;
• and
• transmitting the first trigger frame including a type indicator indicating that the first trigger frame is a shared transmission type of trigger frame and information identifying the designated one or more resource units in said first trigger based frame to be shared, said one or more resource units to be shared being shared resource units.
