First Claim
1. A system, comprising:
- a first transceiver configured to transmit downlink signals to, and to receive uplink signals from, a first plurality of mobile terminals in a geographic area using a telecommunications resource, wherein the first transceiver is configured to transmit downlink signals and receive uplink signals using a time division duplex (TDD) protocol in which downlink signals and uplink signals are transmitted/received during alternating transmit and receive time frames; and
a resource coordination controller coupled to the first transceiver and configured to communicate with a second telecommunications system including a second transceiver configured to transmit downlink signals to, and receive uplink signals from, a second plurality of mobile terminals within the geographic area using the telecommunications resource using a TDD protocol;
wherein the resource coordination controller is further configured to coordinate use of the telecommunications resource by the first transceiver and/or the first plurality of mobile terminals based on use of the telecommunications resource by the second transceiver and/or the second plurality of mobile terminals, and wherein the resource coordination controller is configured to define timing of the transmit and receive time frames in coordination with the timing of transmit and receive time frames used by the second transceiver.

Abstract
A system according to some embodiments includes a first transceiver configured to transmit downlink signals to, and to receive uplink signals from, a first plurality of mobile terminals in a geographic area using a telecommunications resource, and a resource coordination controller coupled to the first transceiver and configured to communicate with a second telecommunications system including a second transceiver configured to transmit downlink signals to, and receive uplink signals from, a second plurality of mobile terminals within the geographic area using the telecommunications resource. The resource coordination controller may be further configured to coordinate use of the telecommunications resource by the first transceiver and/or the first plurality of mobile terminals based on use of the telecommunications resource by the second transceiver and/or the second plurality of mobile terminals.

30. A method of coordinating use of a telecommunications resource by first and second telecommunications systems operating in a common geographic area, the method comprising:
-
coordinating operation of the first and second telecommunications systems so that downlink signals are transmitted to, or uplink signals are received from, a first plurality of mobile terminals within the common geographic area at a first transceiver in the first telecommunications system using a telecommunications resource during a first time frame during which a second transceiver in the second telecommunications system is not using the telecommunications resource in the common geographic area, and so that downlink signals are transmitted to, or uplink signals are received from, a second plurality of mobile terminals within the common geographic area at a second transceiver in the second telecommunications system using the telecommunications resource during a second time frame that is non-overlapping and/or partially overlapping with the first time frame and during which the first transceiver in the first telecommunications system is not using the telecommunications resource; wherein the first transceiver is configured to transmit downlink signals and receive uplink signals using a time division duplex (TDD) protocol in which downlink signals and uplink signals are transmitted/received during alternating transmit and receive time frames, the method further comprising defining timing of the transmit and receive time frames in coordination with the timing of transmit and receive time frames used by the second transceiver. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
