Abstract

According to some embodiments, a method of adapting reference signals of a wireless network comprises establishing a first wireless connection with a first user equipment. The first wireless connection is associated with one or more references signals and each of the one or more reference signals is associated with one or more antenna ports. The method further comprises mapping one of the one or more reference signals associated with one or more antenna ports to at least two antenna port reference signal resources (APRSR) for the first user equipment, wherein the APRSR comprises a pair of consecutive time-frequency resource elements of a radio subframe of the first wireless connection.
