Embodiments of the present disclosure relate to defining and using unlicensed band, or sub-band, combinations for Carrier Aggregation (CA) for a wireless communication system that utilizes a standalone unlicensed technology (e.g., MulteFire or Fifth Generation (5G) New Radio (NR)). In general, a wireless device is configured with a CA combination that includes a Primary Cell (PCell) in a non-Dynamic Frequency Selection (DFS) spectrum and one or more Secondary Cells (SCells), at least one of which is in a DFS spectrum. In this manner, standalone operation in unlicensed spectrum utilizing DFS spectrum is provided.

1. A base station for a wireless communication system, the base station configured to communicate with a User Equipment, UE, and comprising: processing circuitry configured to cause the base station to provide, to the UE, a Carrier Aggregation, CA, combination configuration for the UE that comprises: a Primary Cell, PCell, or Primary Component Carrier, PCC, for the UE in a non-Dynamic Frequency Selection, DFS, spectrum, the non-DFS spectrum being an unlicensed spectrum other than a DFS spectrum; andone or more Secondary Cells, SCells, or Secondary Component Carriers, SCCs, for the UE, wherein the one or more SCells or the one or more SCCs for the UE comprise at least one SCell or SCC in a DFS spectrum. 2. The base station of claim 1 wherein the processing circuitry is further configured to cause the base station to operate in accordance with the CA combination configuration for the UE. 3. The base station of claim 1 wherein the processing circuitry is further configured to cause the base station to configure one or more other network nodes to operate in accordance with the CA combination configuration for the UE. 4. The base station of claim 1 wherein the processing circuitry is further configured to cause the base station to provide the CA combination configuration for the UE to another network node. 5. The base station of claim 1 further comprising a radio interface, wherein the processing circuitry is further configured to cause the base station to provide the CA combination configuration to the UE via the radio interface. 6. The base station of claim 1 wherein the wireless communication system is a cellular communication system. 7. A method implemented in a base station for a wireless communication system, comprising: providing to a User Equipment, UE, a Carrier Aggregation, CA, combination configuration for the UE that comprises: a Primary Cell, PCell, or Primary Component Carrier, PCC, for the UE in a non-Dynamic Frequency Selection, DFS, spectrum, the non-DFS spectrum being an unlicensed spectrum other than a DFS spectrum; andone or more Secondary Cells, SCells, or Secondary Component Carriers, SCCs, for the UE, wherein the one or more SCells or the one or more SCCs for the UE comprise at least one SCell or SCC in a DFS spectrum. 8. The method of claim 7 wherein the method further comprises operating in accordance with the CA combination configuration for the UE. 9. The method of claim 7 further comprising configuring one or more other network nodes to operate in accordance with the CA combination configuration for the UE. 10. The method of claim 7 further comprising providing the CA combination configuration for the UE to another network node. 11. The method of claim 7 wherein the base station comprises a radio interface, and providing the CA combination configuration to the UE comprises providing the CA combination configuration to the UE via the radio interface. 12. The method of claim 7 wherein the wireless communication system is a cellular communication system. 13. A User Equipment, UE, for a wireless communication system, the UE configured to communicate with a base station and comprising: a radio interface; andprocessing circuitry configured to cause the UE to: receive, from the base station via the radio interface, a Carrier Aggregation, CA, combination configuration for the UE that comprises: a Primary Cell, PCell, or Primary Component Carrier, PCC, for the UE in a non-Dynamic Frequency Selection, DFS, spectrum, the non-DFS spectrum being an unlicensed spectrum other than a DFS spectrum; andone or more Secondary Cells, SCells, or Secondary Component Carriers, SCCs, for the UE, wherein the one or more SCells or the one or more SCCs for the UE comprise at least one SCell or SCC in a DFS spectrum; andoperate in accordance with the CA combination configuration. 14. The UE of claim 13 wherein the wireless communication system is a cellular communication system. 15. A method implemented in a User Equipment, UE, for a wireless communication system, comprising: receiving, from a base station, a Carrier Aggregation, CA, combination configuration for the UE that comprises: a Primary Cell, PCell, or Primary Component Carrier, PCC, for the UE in a non-Dynamic Frequency Selection, DFS, spectrum, the non-DFS spectrum being an unlicensed spectrum other than a DFS spectrum; andone or more Secondary Cells, SCells, or Secondary Component Carriers, SCCs, for the UE, wherein the one or more SCells or the one or more SCCs for the UE comprise at least one SCell or SCC in a DFS spectrum; andoperating in accordance with the CA combination configuration. 16. The method of claim 15 wherein the wireless communication system is a cellular communication system. 17-29. (canceled)
