Abstract: Methods and apparatus for efficient communication of backlog information, e.g., backlog information indicating amounts of uplink traffic waiting to transmitted by a wireless terminal are described. Delta backlog reports are used in addition to absolute backlog reports, thus reducing control signaling overhead, at least some information communicated in a delta backlog report being referenced with, respect to a previously transmitted backlog report. A base station uses received backlog information from wireless terminals in determining scheduling of uplink traffic channel segments In some embodiments, the absolute backlog report uses a first fixed size report format, while the delta backlog report using a second fixed size report format, said second size being different from said first fixed size.
