Method of reuse through remote antenna and same channel cell division
First Claim
1. In a cellular communication system having a plurality of service coverage areas each with a base site, at least one of the plurality of service coverage areas having a plurality of shared frequency microcells each having an omnidirectional, remote antenna interconnected with the base site, a method of providing communication services comprising the steps of:
- receiving a request, at the base site, to provide communication access to a communication unit;
simulcasting supervisory audio tone through each omnidirectional, remote antenna of the plurality of shared frequency microcells;
measuring a signal quality factor of a looped-back supervisory audio tone received from the communication unit at each omnidirectional, remote antenna of the plurality of shared frequency microcells; and
establishing a communication link between the communication unit and base site through a selected antenna of said plurality of omnidirectional, remote antennas of the plurality of shared frequency microcells, said selected antenna being selected based upon said signal quality factor of said looped-back supervisory audio tone received at said selected antenna.

Abstract
A method of providing communication services in a cellular communication system which consists of a plurality of service coverage areas having a plurality of shared frequency microcells. Each microcell has an omnidirectional, remote antenna interconnected with a base site. The method consists of receiving a request, at the base site, to provide communication access to a communication unit. A supervisory audio tone is simulcast through each omnidirectional, remote antenna of the plurality of shared frequency microcells. A signal quality factor of a looped-back supervisory audio tone received from the communication unit at each omnidirectional, remote antenna is then measured. A communication link between the communication unit and base site is then established through a selected antenna of said plurality of omnidirectional, remote antennas. The antenna is selected based upon the signal quality factor of the looped-back supervisory audio tone.
