Title: REFERENCE SIGNAL COUPLING IN A WIRELESS NETWORK
Abstract:
According to some embodiments, a method of coupling reference signals of a wireless network comprises establishing a wireless connection with a wireless device. The wireless connection comprises a first reference signal and a second reference signal and both the first and second reference signals are associated with one or more antenna ports. The method further comprises determining a mapping between the one or more antenna ports associated with the first reference signal and the one or more antenna ports associated with the second reference signal; communicating the mapping of antenna ports to the wireless device; and transmitting the first reference signal and the second reference signal to the wireless device according to the communicated mapping.
