ABSTRACT:
A communication system employs a method and apparatus for exchanging communicated signals between a communication unit (e.g., 17) and a central site (205). A remote base site (65) or the central site (205) determines whether a signal must be exchanged between the communication unit (17) and the central site (205). When a signal is to be exchanged, the remote base site (65) allocates a first radio frequency communication resource (75) for use in exchanging the signal between the communication unit (17) and the remote base site (65) and a second radio frequency communication resource (74) for use in exchanging the signal between the remote base site (65) and the central site (205).
