ENHANCED POSITIONING REFERENCE SIGNAL PATTERNS FOR POSITIONING

摘要

Embodiments herein relate to method for transmitting positioning reference signals (PRSs) in a cell served by a base station. The base station maps PRSs onto different groups of time-frequency resources according to different respective PRS patterns, wherein each of the different groups spans one or more consecutive subframes in time. The base station transmits the PRSs in the cell in accordance with said mapping.
