1. A method comprising:
- negotiating with a first wireless node a first negotiated delivery interval for a specific multicast service by a transmitting wireless node in a wireless network based on a Delivery Traffic Indication Map (DTIM) interval, andsending information from the transmitting wireless node to the first wireless node based on the first negotiated delivery interval;
wherein the first negotiated delivery interval comprises an integer multiple number of DTIM intervals.

Abstract
Various embodiments are described relating to determining delivery intervals in a wireless network, such as an 802.11 infrastructure network. In an example embodiment, a first negotiated delivery interval for a first wireless node may be negotiated by a transmitting wireless node in a wireless network based on a multicast service setup operation and a Delivery Traffic Indication Map (DTIM) interval. Information may be sent from the transmitting wireless node to the first wireless node based on the first negotiated delivery interval. According to an example embodiment, the first negotiated delivery interval may include an integer multiple number of DTIM intervals.
