摘要： Methods and apparatus for efficiently scheduling links in wireless communications networks are described. Various described methods and apparatus are well suited for use in ad hoc wireless networks in which scheduling decisions are made in a distributed and/or decentralized manner. In some embodiments, the links in a network, e.g., in a peer to peer ad hoc network, are adaptively grouped based on comparable link channel gain. Exemplary signaling used, in some but not necessarily all embodiments, by devices to estimate channel gains include broadcast connection identifier signals and reverse broadcast connection identifier signals. Grouping links into sets based on comparable link channel gain, and selectively ordering the scheduling priorities of the different groups, is used to improve scheduling efficiency, e.g., decrease the likelihood that unnecessary yielding occurs.

摘要： An apparatus, a method of the apparatus, and a computer program in the apparatus are provided in which the apparatus determines a group to which each of a plurality of wireless devices is associated based on signals received from the plurality of wireless devices. The apparatus selects a group for access to a wireless medium from a plurality of groups based on the group determined for each of the plurality of wireless devices and based on reducing interference with the plurality of wireless devices. Each of the plurality of groups has a different priority. The apparatus communicates using peer-to-peer communication on the wireless medium with a priority based on the selected group.
