In some embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to a mechanism for peer devices to transmit availability schedules beyond 512 time units while continuing to minimize communication overhead. In some embodiments, a wireless station may discover a peer wireless station and transmit extended availability information. In some embodiments, the extended availability information may indicate one or more of an availability interval duration, a bitmap length, and/or a repeat interval of the availability information. In some embodiments, the extended availability information may indicate a maximum number of receivable spatial streams and/or a channel bandwidth. In some embodiments, the extended availability information may include or indicate availability of the wireless station for more than 512 time units.
