Abstract
Apparatus and methods of performing interference mitigation in a communication network. The interference mitigation can include a controller sending a message to a first access point instructing the first access point to measure at least one signal transmitted by a first wireless terminal communicating a signal having known characteristics; the controller receiving from the first access point signal measurement information; and the controller communicating at least some of the signal measurement information received from the first access point to a second access point.
Claims25
A method of performing interference mitigation in a communication network, the method comprising:
- a controller sending a message to a first access point instructing the first access point to measure at least one signal transmitted by a first wireless terminal communicating a signal having known characteristics, the measurement of the at least one signal being used by the first access point in calculating an interference cost associated with the first wireless terminal;
- the controller receiving from the first access point signal measurement information including the calculated interference cost;
- and
- the controller communicating at least some of the signal measurement information, including the calculated interference cost, received from the first access point to a second access point responsible for scheduling uplink transmissions of the first wireless terminal in accordance with the interference cost.
A control node comprising:
- a transmitter module configured to send a message to a first access point instructing the first access point to measure at least one signal transmitted by a first wireless terminal communicating a signal having known characteristics, wherein the measurement of the at least one signal is used by the first access point in calculating an interference cost associated with the first wireless terminal;
- a receiver module configured to receiving from the first access point signal measurement information including the calculated interference cost;
- and
- a measurement information communication module configured to communicate at least some of the signal measurement information, including the calculated interference cost, received from the first access point to a second access point responsible for scheduling uplink transmissions of the first wireless terminal in accordance with the interference cost.
A non-transitory computer readable medium comprising computer executable instructions stored thereon, which, when executed cause a controller to perform the operations of:
- sending a message to a first access point instructing the first access point to measure at least one signal transmitted by a first wireless terminal communicating a signal having known characteristics, wherein the measurement of the at least one signal is used by the first access point in calculating an interference cost associated with the first wireless terminal;
- receiving from the first access point signal measurement information including the calculated interference cost;
- and
- communicating at least some of the signal measurement information, including the calculated interference cost, received from the first access point to a second access point responsible for scheduling uplink transmissions of the first wireless terminal in accordance with the interference cost.
