Abstract
An eNodeB uses a first portion of a frequency spectrum as a primary cell and uses a second portion of the frequency spectrum as a secondary cell that is dynamically shared with a 5G base station. The eNodeB and the 5G base station communicate to dynamically share the second portion of the frequency spectrum.
Claims20
A system comprising:
- a first base station utilizing a first radio access technology to communicate with first user equipment, wherein the first base station uses a frequency spectrum during a first time period;
- and
- a second base station utilizing a second radio access technology to communicate with second user equipment, wherein the second base station uses a portion of the frequency spectrum during a second time period,
- wherein the second base station is configured to send to the first base station a request that the first base station make the portion of the frequency spectrum available for use during the first time period by the second base station,
- wherein the second user equipment is configured to determine that the portion of the frequency spectrum is unavailable during the first time period responsive to a detected absence of one or more pilot tones in the portion of the frequency spectrum in the first time period.
2 more elements
A method comprising:
- dynamically sharing, by a processing system including a processor and utilizing a first radio access technology, a frequency spectrum with a second radio access technology,
- wherein a first base station utilizes the first radio access technology to communicate with first user equipment, the first base station using the frequency spectrum during a first time period;
- and
- wherein a second base station utilizes a second radio access technology to communicate with second user equipment, the second base station using a portion of the frequency spectrum during a second time period,
- wherein the second base station is configured to send to the first base station a request that the first base station make the portion of the frequency spectrum available for use during the first time period by the second base station,
- wherein the second user equipment is configured to determine that the portion of the frequency spectrum is unavailable during the first time period responsive to a detected absence of one or more pilot tones in the portion of the frequency spectrum in the first time period.
3 more elements
A device comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations comprising:
- dynamically sharing, by a first radio access technology, a frequency spectrum with a second radio access technology,
- wherein a first base station utilizes the first radio access technology to communicate with first user equipment, the first base station using the frequency spectrum during a first time period;
- and
- wherein a second base station utilizes the second radio access technology to communicate with second user equipment, the second base station using a portion of the frequency spectrum during a second time period,
- wherein the second base station is configured to send to the first base station a request that the first base station make the portion of the frequency spectrum available for use during the first time period by the second base station,
- wherein the second user equipment is configured to determine that the portion of the frequency spectrum is unavailable during the first time period responsive to a detected absence of one or more pilot tones in the portion of the frequency spectrum in the first time period.
