Abstract
Methods, systems, and devices are described for peer-to-peer (P2P) group owner (GO) multi-channel concurrent (MCC) operation and an associated absence period indication for legacy client devices. In some aspects, an absence period during which a peer-to-peer (P2P) group owner (GO) is unavailable to receive transmissions from client devices wirelessly coupled with the P2P GO may be identified. A notice of absence (NoA) may be transmitted by the P2P GO, the P2P NoA indicating the absence period if the client devices wirelessly coupled with the P2P GO include a P2P client device that supports a P2P protocol. A legacy wireless beacon may be transmitted by the P2P GO, the legacy wireless beacon comprising an information element (IE) indicating the absence period if the client devices wirelessly coupled with the P2P GO include a legacy client device that does not support the P2P protocol.
