Section: 6.10.4.2 Mapping to resource elements
Content: If PRS frequency hopping is not configured by higher layers, the reference signal sequence shall be mapped to complex-valued modulation symbols used as reference signal for antenna port in slot according to where Normal cyclic prefix: Extended cyclic prefix: The bandwidth for positioning reference signals is configured by higher layers and the cell-specific frequency shift is given by where if no value for is configured by higher layers. If PRS frequency hopping is configured by higher layers, a PRS frequency hopping configuration provided by higher layers contains the following: - The length of the PRS occasion group, - Number of PRS frequency hopping bands, - defined as twice the starting PRB index of PRS frequency hopping band where - if , - where is the index of the first PRB in the PRS frequency hopping narrowband configured by higher layers if If PRS frequency hopping is configured by higher layers, the reference signal sequence in the PRS occasion , , in the PRS occasion group shall be mapped to complex-valued modulation symbols used as reference signal for antenna port in slot according to where - for normal cyclic prefix - for extended cyclic prefix Figure 6.10.4.2-1: Mapping of positioning reference signals (normal cyclic prefix) Figure 6.10.4.2-2: Mapping of positioning reference signals (extended cyclic prefix)
