NR DL PRS resource muting and enhanced multi-RTT procedure

Described herein is an apparatus of a next generation NodeB (gNB). The apparatus comprises: one or more processors configured to determine a downlink (DL) positioning reference signal (PRS) configuration, the DL PRS configuration comprising a defined DL PRS resource set configuration and a DL PRS resource muting mechanism, wherein the defined DL PRS resource set configuration maintains an extension mechanism using a selected one of DL PRS resource set repetition or occasion dependent time and frequency offset for the DL PRS resource set; and to generate a PRS based on the DL PRS configuration. 本文描述的是一种下一代NodeB(gNB)的装置。该装置包括：一个或多个处理器，被配置为：确定下行链路(DL)定位参考信号(PRS)配置，DL PRS配置包括定义的DL PRS资源集配置和DL PRS资源静默机制，其中，定义的DL PRS资源集配置使用DL PRS资源集重复或用于DL PRS资源集的时机依赖时间和频率偏移中选定的一个来维护扩展机制；以及基于DL PRS配置，生成PRS。
