    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.

    Abstract translation: 讨论了用于减轻无线通信环境中的干扰的技术,其中相邻小区可以具有异步时分双工配置。 可以在发射eNodeB的下行链路(DL)传输的照明演进节点B(eNodeB)进行测量。 这些测量可以通过回程链路中继到发射eNodeB,并用于进行调度,传输功率和/或波束形成决策以减少DL干扰的可能性。 为了减少UpLink(UL)干扰,可以由用户设备(UE)的发射eNodeB请求子帧特定测量,该UE将从发射eNodeB接收DL传输,以检测来自执行到相邻eNodeB的UL传输的任何UE的干扰。 干扰测量可以被发射eNodeB用于进行调度确定以减轻干扰。

    Abstract: An apparatus and system of uplink timing adjustment for frequency range 2 (FR2) communication with remote radio heads (RRHs) in a unidirectional high speed train (HST) deployment are described. A one-shot uplink timing adjustment is applied when a first value is greater than a second value. The first value is a difference between an end of a first transmission from a neighboring RRH and an end of reception of the first transmission at the UE less a difference between an end of a second transmission from a serving RRH and an end of reception of the second transmission at the UE. The second value is a predetermined gradual timing adjustment set by a 3GPP specification, the predetermined adjustment plus a timing error limit, the predetermined adjustment plus twice a downlink error, or a multiple of the predetermined adjustment. The one-shot uplink timing adjustment is twice the first value.
