    Abstract: Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.

    Abstract translation: 提供了用于分区资源以增强小区间干扰协调（eICIC）的方法和装置。 某些方面涉及广播指示时域资源划分信息（RPI）的消息，其中用户设备（UE）可以在空闲模式下操作。 利用RPI，UE可能能够识别来自相邻小区的减少/消除的干扰的受保护资源。 该广播消息中的RPI可以被编码为位图，作为U / N / X子帧的枚举的替代或补充。 其他方面需要发送指示时域RPI的专用或单播消息，其中UE可以在连接模式下操作。 利用RPI，UE可以在受保护的基站期间基于来自服务基站的一个或多个信号来确定信道状态信息（CSI），进行无线电资源管理（RRM）测量或执行无线电链路监视（RLM） 时域资源。

    Abstract: Systems and methods for facilitating inter-cell interference coordination using resource partitioning are described. A UE may receive or determine information related to received interference and/or future scheduling. The information may be communicated to a serving base station, which may use the information to allocate uplink or downlink resources between cells. The uplink and/or downlink resource may be partitioned in subbands to mitigate interference from adjacent network nodes. The eNBs may communicate, such as directly, via a backhaul connection, and/or between UEs to configure interference coordination and signaling.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping. In some implementations, a user equipment (UE) may receive a discovery reference signal (DRS) including a skipping signal identifying one or more UEs, may stay on an anchor channel when the skipping signal identifies the UE, and may switch from the anchor channel to a first downlink (DL) hopping channel of a DL frequency hopping pattern when the signal does not identify the UE. In some other implementations, a base station (BS) may be configured to output a DRS including a skipping signal identifying one or more UEs, output a signal indicating a channel occupancy time (COT) obtained on a first DL hopping channel of a DL frequency hopping pattern, and output DL data on the first DL hopping channel of the DL frequency hopping pattern.

    Abstract: Technology neutral coexistence and high priority traffic is disclosed for use in unlicensed frequency bands. Synchronization boundaries are defined in which synchronous contention windows across all radio access technologies attempting access to a shared communication channel occur periodically. Between the synchronous contention windows, the nodes may return to asynchronous access procedures. Such synchronous access procedures may be applicable to certain power classes or deployment type nodes. Additionally, various priority schemes for the synchronous contention window may be used to ensure protection of higher priority nodes or traffic, such as ultra-reliable low latency communication (URLLC) traffic. According to certain aspects, the deployment of such synchronous access methodology may be triggered via signaling from initiating devices. Additional aspects may provide for a technology neutral receiver protection mechanism by defining resources for protection signaling during receiver protection intervals between successive synchronous contention windows.
