Apparatus and method for performing radio environment reporting on a
reverse common signaling channel. When a dedicated RF connection between
a remote unit (RU) (118) and infrastructure equipment (109) is being
released, the RU receives a first message from the infrastructure
instructing the RU to perform occasional pilot strength reporting on the
reverse common signaling channel (r-csch) while the RU is in the idle
state. In the preferred embodiment, the pilot strength reporting is
limited by a maximum number of reports and/or a time limit to preserve
battery life and prevent r-csch congestion in the system. Preferably, a
Radio Environment Report Message, referred to generally herein as a
second message, carries radio environment information (REI), such as
pilot strength and phase of the best pilots measured, and helps the
infrastructure both with tracking the RU location and with selecting a
strong set of pilots for channel assignment.
