    Abstract: In a system where a first node provides a first area of TDD coverage on a first TDD carrier using a first TDD configuration and an adjacent second node provides a second area of TDD coverage on a second TDD carrier using a different second TDD configuration, the first node could additionally provide an area of FDD coverage on a first FDD carrier, including causing the area of FDD coverage to sit at least partially between the first and second areas of TDD coverage and therefore to define a spatial buffer between the first and second areas of TDD coverage. For instance, the first access node could restrict its service on the first TDD carrier to be for user equipment devices (UEs) that are relatively close to the first access node and could restrict its service on the first FDD carrier to be for UEs that are relatively far away from the first access node.

    Abstract: Disclosed is a method and system for managing carriers on which a wireless communication system serves a UE over an established radio-link-layer connection. As disclosed, a base station serves the UE with carrier aggregation service using (i) a first carrier as a primary carrier for the UE and (ii) a second carrier as a secondary carrier for the UE. While serving the UE, the system determines that the base station should serve the UE with the carrier aggregation service using (i) the first carrier as the secondary carrier and (ii) the second carrier as the primary carrier. In response to the determination and while maintaining the established radio-link-layer connection with the UE, the system causes the base station to serve the UE with the carrier aggregation service using (i) the first carrier as the secondary carrier and (ii) the second carrier as the primary carrier.
