Abstract:
A method and corresponding system to help manage carrier-aggregation service in view of possible intermodulation distortion between component carriers. When a base station is serving a UE with carrier aggregation service on at least two component carriers, the base station determines that uplink communication on the two component carriers is likely to combine to produce an intermodulation product that falls within the downlink channel of one of the component carriers, and that the power level of that intermodulation product is likely to be threshold high. In response, the base station then modifies the set of component carriers on which the base station provides the UE with carrier aggregation service, to help reduce or avoid associated intermodulation distortion.
Abstract:
A method and system to help address this issue. When a device is within coverage of a cell that operates with a particular TDD configuration, the device will determine based on its location a set of one or more TDD frame configurations that the device would support, which could be based on maximum uplink transmission power of the UE, permitted maximum transmission power in the location, and uplink duty cycle defined by each of the various TDD configurations. The UE will then control whether or not it will be served by the cell based on whether the TDD configuration of the cell is within the determined set.
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.
