Abstract
A system for interference mitigation through carrier aggregation may include one or more processors and a memory. The memory may include instructions that, when executed by the one or more processors, cause the one or more processors to: provide data transmissions and control transmissions to a wireless device over a primary component carrier, determine that interference exists on the primary component carrier, and switch at least a portion of the data or control transmissions to a secondary component carrier in response to determining that the interference exists on the primary component carrier, while maintaining connectivity on the primary component carrier.
Claims26
A method for mitigating interference through carrier aggregation, the method comprising:
- transmitting data and control information over a primary component carrier to a wireless device;
- receiving, from the wireless device, a first message that indicates interference on the primary component carrier, wherein the first message comprises at least one of first measurement information indicating the interference on the primary component carrier, technology information identifying a technology which is causing or receiving the interference, an originating frequency from which the interference originates, a frequency to which the interference is caused, an interference pattern, a list of new cells having less interference than the primary component carrier, or second measurement information for the new cells;
- and
- in response to the first message, transmitting at least a portion of the data and control information to the wireless device over a secondary component carrier that is in carrier aggregation with the primary component carrier while maintaining connectivity with the wireless device over the primary component carrier.
A non-transitory machine readable medium embodying instructions that, when executed by a machine, cause the machine to perform a method for mitigating interference through carrier aggregation, the method comprising:
- receiving data transmissions and control transmissions over a primary component carrier from a base station;
- determining that the primary component carrier is experiencing, or causing, interference;
- transmitting a first message to the base station that indicates the interference with respect to the primary component carrier;
- receiving at least a portion of the data transmissions or at least a portion of the control transmissions over a secondary component carrier from the base station while maintaining a connection with the base station over the primary component carrier;
- determining that the interference has diminished and transmitting, to the base station, a second message that indicates that the interference has diminished;
- and
- receiving the data transmissions and the control transmissions from the base station over the primary component carrier.
A system, comprising:
- one or more processors;
- and
- a memory including instructions that, when executed by the one or more processors, cause the one or more processors to:
- provide data transmissions and control transmissions to a wireless device over a primary component carrier;
- determine that interference exists on the primary component carrier;
- switch at least a portion of the data transmissions or at least a portion of the control transmissions to a secondary component carrier in response to determining that the interference exists on the primary component carrier, while maintaining connectivity on the primary component carrier;
- and
- switch the at least the portion of the data transmissions or the at least the portion of the control transmissions to the primary component carrier in response to determining that the interference on the primary component carrier has diminished.
