An initial reporting structure for an uplink dedicated control channel is used by a wireless terminal following a transition into a state of wireless terminal operation or action which makes it desirable to provide a base station with an initial set of control information which can be used to support uplink transmission of user data. Subsequently while continuing operation in a state supporting uplink transmission of user data, a recurring scheduled reporting structure for the uplink dedicated control channel is followed by the wireless terminal. The initial reporting structure provides for communication of at least some information reports, e.g., infrequently scheduled reports, which may not have been otherwise communicated during the same time interval if the recurring scheduled reporting structure had not been overridden. Thus the use of initial report sets facilitates a rapid overall understanding by the serving base station attachment point of the wireless terminal's status.
