Abstract: Use is made of the Notice-of-Absence (NoA), as is a Wi-Fi/Bluetooth time sharing mechanism. This mechanism dictates ‘n’ cycles of absent and present duration of P2P-GO starting at a defined time ‘t’. The information bits of NoA are communicated from GO to the Client in the Beacons (for the period of NoA in use). Time-sharing between Bluetooth and WLAN at P2P-GO, is communicated using NoA to the P2P-Client. For the duration of both Bluetooth and WLAN radios transmitting/receiving traffic, NoA is used such that the absent duration covers the Bluetooth Interval and present-duration covers the WLAN interval. This NoA remains effective for as long as the time-sharing mode between BT and WLAN radios. As soon as, P2P-GO enters the time-sharing mode, NoA parameters are determined based on the timesharing mode (Dynamic Long and Dynamic Short). The start time of NoA schedule is determined after synchronizing to the time-sharing scheduler. The start time of NoA schedule is ‘n’ TBTTs after entering the time-sharing mode so that the Clients have ample opportunity to receive the NoA information. Until NoA schedule starts, P2P-GO may protect Bluetooth Interval using CTS2S frames. After NoA schedule comes into play, P2P-GO may send CTS2S only for asynchronous Bluetooth traffic.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured to identify interference information associated with at least one traffic stream. The apparatus is further configured to transmit a message to an access point. The message includes a stream ID associated with the interference information and with the at least one traffic stream. The message includes the interference information, and the interference information includes an offset value and an interval/duration value.
