Abstract: Some embodiments include an apparatus, method, and computer program product for dynamic window access point (AP) power save enhancements. Some embodiments include transmitting an availability window (AW) of an AP to stations (STAs) and dynamically modifying the AW. In some embodiments, a mobile device may perform soft AP functions and associate with the stations. The modifications can include truncating or extending the AW. Some embodiments include: a broadcast availability frame that informs STAs of the modified AW; an Availability Clear To Send (A-CTS) frame that allows the AP to inform associated STAs of the modified AW; and/or an uplink (UL) multi-user (MU)-Request to Send (RTS) Enabled feature, that allows an AP to be available while operating in a low power receive (LPR) state (e.g., low power mode) and transition to a full power state to receive data using a bandwidth greater than 20 MHz.

Abstract: Some embodiments include an apparatus, method, and computer program product for infrastructure and peer-to-peer (P2P) medium access sharing. Some embodiments enable an access point (AP) to assist associated stations (STAs) in accessing a channel. In some embodiments, an AP can receive a request for coordinated transmission for peer-to-peer (P2P) communications, determine a bandwidth available for use during a transmit opportunity (TXOP), and allocate, from the bandwidth, a first subset of one or more channels for infrastructure communications and a second subset of one or more channels for the P2P communications responsive to the request. The AP can transmit to a STA, a first signal corresponding to the second subset of one or more channels for the P2P communications, indicating that the second subset of one or more channels can be used for P2P communications during the TXOP.
