doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> May, 2006 Purpose Channel model sub-committee requires a common channel model for evaluation of PHY layer proposals Bulk of proposed applications require directional antennas Committee needs a model with AoA Require a measurement campaign to: Determine an appropriate channel model with AoA Determine the set of parameters that accurately describes the 60 GHz channel for indoor situations This submission is an update on work presented in 06/0112r00 (Denver, March 2006) Tony Pollock, NICTA Tony Pollock, NICTA

Recall: Proposed Channel Model ref: 15-06-0103-00 May, 2006 Recall: Proposed Channel Model ref: 15-06-0103-00 S-V Model with AoA extension L = number of clusters; Kl = number of multipath components (number of rays) in the l-th cluster; = multipath gain coefficient of the k-th ray in the l-th cluster; Tl = arrival time of the first ray of the l-th cluster; k,l = delay of the k-th ray within the l-th cluster relative to the first path arrival time, Tl; = mean angle of arrival of l-th cluster; = angle of arrival of the k-th ray within the l-th cluster.
