Non-frequency translating repeater with detection and media access control
First Claim
1. A method for non-regenerative repeating of a signal transmitted from a first station to a second station according to a Time Division Duplex (TDD) protocol, the first station communicating to the second station on a downlink and the second station communicating to the first station on an uplink, the method comprising:
- detecting the presence of the signal in an interval associated with one or more of the uplink and the downlink;
re-transmitting the signal from the second station to the first station using a first antenna directed toward the first station if the signal is detected on the uplink; and
re-transmitting the signal from the first station to the second station using one of a second antenna directed toward the second station, and an omni-directional antenna, if the signal is detected on the downlink, wherein a form factor associated with one or more of the first antenna, the second antenna, and the omni-directional antenna facilitates the detecting and the re-transmitting.

Abstract
A non-frequency translating repeater (110, 210, 300) for use in a time division duplex (TDD) radio protocol communications system includes detection retransmission and automatic gain control. Detection is performed by detectors (309, 310) and a processor (313). Detection can be overridden by processor (313) using logic elements (314). Antennae (220, 230) having various form factors can be used to couple a base station (222) to a subscriber terminal (232) which can be located in a sub-optimal location such as deep inside a building or the like.
