Documents summarizing Comment Resolution.cmtr file uploaded to TGj server –Filename: 28_Data Forwarding, QoS_adhoc.cmtr.xls files uploaded to the Temp server –A version showing outcome of each ad-hoc meeting ForwardingAhGComments-AhG-4thMeeting.xls –A version showing the consolidated comments only ForwardingAhGComments-Prep4Upload.xls Will be submitted for batch resolution

5. Clarification from other groups Definitions of an RS group –Where is the end point of a Tunnel? –Definitions MR-BS or RS with a group of subordinate Transparent RSs MR-BS or RS with a group of subordinate Non-Trans RSs –One where the group sens the same premable as superordinate –One where the group sends different preamble as the superordinate Systematic CID allocation –Perhaps called Localized CID allocation now? –Inputs from Aik Chindapol, Jung Je, and Saito-san

6. Motion for Batch Resolution Motion: To accept the proposed resolutions in C802.1 6j-07/574.xls as the resolutions to the respective com ments in the LB#28 database.
