Abstract:
1. A method of performing positioning-related measurements in a wireless communication apparatus associated with a wireless communication network that includes one or more first cells each transmitting a first type of reference signals but not a second type of reference signals and one or more second cells each transmitting at least the second type of reference signals, said apparatus comprising: receiving a mix of reference signals, including one or more of the first type of reference signals from one or more of said first cells and one or more of the second type of reference signals from one or more of said second cells; and performing positioning-related measurements based on which a given positioning-related calculation is made, by performing those measurements at said wireless communication apparatus using said mix of reference signals; wherein said first type of reference signals comprises reference signals on which the wireless communication apparatus is capable of performing positioning-related measurements without measurement ambiguity even if those reference signals are transmitted from more than one antenna port at a time within a cell, and wherein said second type of reference signals comprises reference signals on which the wireless communication apparatus is capable of performing positioning-related measurements without measurement ambiguity only if those reference signals are transmitted from one antenna port at a time within a cell.
