Abstract
Methods and apparatus at an evolved Node B (eNB) and user equipment (UE) in cells operating in time division duplex with a first configuration and having a neighbor cell eNB operating in time division duplex with a second configuration, the methods and apparatus: identifying potential eNB-to-eNB; UE-to-UE; eNB-to-UE; and UE-to-eNB interference. Further methods and apparatus to report interference including enumerated interference types to neighbor cell eNBs. Further, methods and apparatus for interference mitigation.
Claims26
A method at an evolved Node B (eNB) for a cell operating in time division duplex with a first configuration and having a neighbor cell eNB operating in time division duplex with a second configuration, the method comprising:
- receiving, from the neighbor cell eNB, an interference indication containing an indication of an interference type;
- and
- performing interference mitigation based on the interference type.
An evolved Node B (eNB) for a cell and operating in time division duplex with a first configuration and having a neighbor cell eNB operating in time division duplex with a second configuration, the eNB comprising:
- a processor;
- and
- a communications subsystem,
- wherein the eNB is configured to:
- receive, from the neighbor cell eNB, an interference indication containing an indication of an interference type;
- and
- perform interference mitigation based on the interference type.
