Cellular communications spectrum management
First Claim
1. One or more devices comprising:
- one or more processors; and
memory storing instructions that, when executed by the one or more processors, configure the one or more devices to;
send a system information message identifying a clean communication cell associated with a first portion of spectrum assigned to an entity;
send a resource allocation message to a client device, the resource allocation message instructing the client device to use the clean communication cell for uplink transmissions and to use a forbidden communication cell for at least a portion of downlink transmissions; and
use the clean communication cell to receive the uplink communications from the client device,wherein the forbidden communication cell is associated with a second portion of spectrum assigned to the entity that is also available for uplink communications by an incumbent entity.

Abstract
The techniques described herein enable a commercial cellular service provider to use a repurposed portion of spectrum to provide cellular service to a customer base while ensuring that the use of the repurposed portion of spectrum does not interfere with a previous use of the repurposed portion of spectrum by an incumbent entity. The techniques determine, and manage the use of, forbidden cells and clean cells. A “forbidden” cell is a cell in which a previous use of spectrum by an incumbent entity is protected. A “clean” cell is a cell that can be freely used by the commercial cellular service provider without a possibility of interference with a protected use of the spectrum by the incumbent entity.

9. A computer-implemented method comprising:
-
sending a system information message identifying a clean communication cell associated with a first portion of spectrum assigned to an entity; sending a resource allocation message to a client device, the resource allocation message instructing the client device to use the clean communication cell for uplink transmissions and to use a forbidden communication cell for at least a portion of downlink transmissions; and using the clean communication cell to receive the uplink transmissions from the client device, wherein the forbidden communication cell is associated with a second portion of spectrum assigned to the entity that is also available for uplink communications by an incumbent entity. - View Dependent Claims (10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium having programming instructions stored thereon that, when executed by a processor of a computing device, cause the computing device to perform operations comprising:
-
sending a system information message identifying a clean communication cell associated with a first portion of spectrum assigned to an entity; sending a resource allocation message to a client device, the resource allocation message instructing the client device to use the clean communication cell for uplink transmissions and to use a forbidden communication cell for at least a portion of downlink transmissions; and using the clean communication cell to receive the uplink transmissions from the client device, wherein the forbidden communication cell is associated with a second portion of spectrum assigned to the entity that is also available for uplink communications by an incumbent entity. - View Dependent Claims (16, 17, 18, 19, 20)
