Abstract

Communication devices, systems, and methods for dynamic cell bonding (DCB) for networks and communication systems are disclosed. In one embodiment, a method of operating a wireless communication system is provided. The method includes determining a first plurality of remote units in a cloud bonded to a communication session, measuring a received signal strength from each of the first plurality of remote units, and measuring a received signal strength from each of a second plurality of remote units in the cloud not bonded to the communication session. One or more of the second plurality of remote units is dynamically bonded to the communication session if the measured received signal strength of the one of the second plurality of remote units is greater than the measured received signal strength of the first plurality of remote units.

Claims

1. A method of operating a wireless communication system, comprising:

(a) determining a first plurality of remote units in a cloud bonded to a communication session;

(b) measuring at least one of a received signal strength and a data rate from each of the first plurality of remote units;

(c) measuring at least one of a received signal strength and an estimated data rate from each of a second plurality of remote units in the cloud not bonded to the communication session;

(d) dynamically bonding one of the second plurality of remote units to the session if the at least one of the measured received signal strength and the estimated data rate of the one of the second plurality of remote units is greater than the at least one of the measured received signal strength and the data rate of one of the first plurality of remote; and

(e) unbonding the one of the first plurality of remote units from the communication session, wherein

the communication session is comprised of a Multiple Input/Multiple Output (MIMO) session.

2. The method of claim 1, wherein the first plurality of remote units in the cloud is coupled to a service unit, and the second plurality of remote units in the cloud is coupled to the service unit.

3. The method of claim 2, wherein the first plurality of remote units in the cloud are within a line of sight of each other and wherein the second plurality of remote units in the cloud are within the line of sight.

4. The method of claim 2, wherein dynamically bonding the one of the second plurality of remote units to the communication session is repeated for each of the second plurality of remote units.

5. The method of claim 2, wherein dynamically bonding the one of the second plurality of remote units and unbonding the one of the first plurality of remote units from the communication session are repeated approximately every predetermined period of time of less than one second.

6. A controller comprising:

a head-end unit communicatively coupled to and configured to conduct a communication session with a first plurality of remote units and a second plurality of remote units;

where the head-end unit is configured to;

(a) determine the first plurality of remote units in a cloud bonded to a communication session;

(b) measure at least one of a received signal strength and a data rate from each of the first plurality of remote units;

(c) measure at least one of a received signal strength and an estimated data rate from each of the second plurality of remote units in the cloud not bonded to the communication session;

(d) dynamically bond one of the second plurality of remote units to the communication session if at least one of the measured received signal strength and the estimated data rate of the one of the second plurality of remote units is greater than the at least one of the measured received signal strength and the data rate of one of the first plurality of remote units; and

(e) repeat dynamically bonding the one of the second plurality of remote units to the communication sessions and unbonding the one of the first plurality of remote units to the communication session approximately every predetermined period of time of less than one second.

7. The controller of claim 6, wherein the communication session is comprised of a Multiple Input/Multiple Output (MIMO) session, and wherein the head-end unit is further configured to unbond the one of the first plurality of remote units from the communication session.

8. A system, comprising:

a plurality of remote units; and

a head-end unit communicatively coupled to and configured to conduct a communication session with a first plurality of remote units and a second plurality of remote units comprising a controller for directing a signal to the plurality of remote units,

wherein the head-end unit is configured to;

(a) determine the first plurality of remote units in a cloud bonded to the communication session;

(b) measure at least one of a received signal strength and a data rate from each of the first plurality of remote units;

(c) measure at least one of a received signal strength and an estimated data rate from each of a second plurality of remote units in the cloud not bonded to the communication session; and

(d) dynamically bond one of the second plurality of remote units to the communication session if at least one of the measured received signal strength and the estimated data rate of the one of the second plurality of remote units is greater than at least one of the measured received signal strength and the data rate of one of the first plurality of remote units, wherein

the first plurality of remote units and the second plurality of remote units are coupled to a service unit.

9. The system of claim 8, wherein the head-end unit is configured to repeat dynamically bonding the one of the second plurality of remote units to the communication session for each of the second plurality of remote units.

10. The system of claim 8, wherein the first plurality of remote units in the cloud are within line of sight of each other and wherein the second plurality of remote units in the cloud are within the line of sight.

11. The system of claim 8, wherein the head-end unit is further configured to unbond the one of the first plurality of remote units from the communication session, and wherein the communication session is comprised of a Multiple Input/Multiple Output (MIMO) session.

12. The system of claim 8, wherein the head-end unit is configured to repeat dynamically bonding the one of the second plurality of remote units to the communication session and unbonding the one of the first plurality of remote units from the communication session approximately every predetermined period of time.
