  • Patent number: 9820250
    Abstract: Technology is discussed for mitigating interference in a wireless communication environment where adjacent cells can have asynchronous Time Division Duplexing configurations. Measurements can be taken at an illuminated evolved Node B (eNodeB) of DownLink (DL) transmissions from a transmit eNodeB. These measurements can be relayed to the transmit eNodeB over a backhaul link and used to make scheduling, transmission power, and/or beam forming decisions to reduce the potential for DL interference. To reduce UpLink (UL) interference, sub-frame specific measurements can be requested by a transmit eNodeB of a User Equipment (UE) that would receive DL transmission from the transmit eNodeB to detect interference from any UEs performing UL transmission to an adjacent eNodeB. The interference measurements can be used by the transmit eNodeB to make scheduling determinations to mitigate the interference.
