Abstract: Technology is discussed for supporting wireless communication paths from an antenna array with a vertical directional component. Examples reduce training feedback for increased numbers of communication paths by only reporting on a subset of Reference Signals (RSs) provided for various vertical beam configurations. Additional examples reduce feedback with virtual measurements based on a difference between RS measurements. One such measurement can come from full set of RSs for a reference beam configuration and another from a partial set of RSs for an additional beam configuration. Such virtual measurements can also be based on cross correlation for beamforming weights associated with the two configurations. Several examples of preparing and sending measurement reports consistent with Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards are discussed. The supporting technology also increases diversity and reduces a power differential between spatially multiplexed layers transmitting a common codeword.

Abstract: Embodiments of circuitry to be included in a user equipment (“UE”) and an evolved Node B (“eNB”) are described. To accelerate the detection of one or more cells in a wireless network, a UE may perform Radio Resource Management (“RRM”) measurements based on one or more synchronization signals instead of based on a common reference signal (“CRS”). Alternatively, the UE may perform RRM measurements for a cell based on a CRS transmitted for the cell without synchronizing to the cell using one or more synchronization signals. The UE may report the RRM measurements to an cNB that is to serve the UE.

Abstract translation: 描述要包括在用户设备（“UE”）和演进节点B（“eNB”）中的电路的实施例。 为了加速对无线网络中的一个或多个小区的检测，UE可以基于一个或多个同步信号而不是基于公共参考信号（“CRS”）执行无线电资源管理（“RRM”）测量。 或者，UE可以基于为小区发送的CRS而对小区执行RRM测量，而不使用一个或多个同步信号与小区同步。 UE可以将RRM测量报告给将用于UE的cNB。

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive an information element (IE) that includes: a higher layer parameter that indicates a plurality of modulation and coding scheme (MCS) thresholds; and another higher layer parameter that includes a plurality of resource block (RB) thresholds. The UE may determine a time density of phase tracking reference signal (PT-RS) to be transmitted by the UE based at least partly on a comparison between a MCS and the plurality of MCS thresholds. The UE may determine a frequency density of the PT-RS based at least partly on a comparison between a scheduled bandwidth and the plurality of RB thresholds. The UE may encode the PT-RS for transmission in accordance with the determined time density and the determined frequency density.
