Abstract: A method and apparatus for implementing reference signal transmissions in a wireless communication system. In one embodiment, the method includes the cell, transmission point (TP), or transmission and reception point (TRP) broadcasting a first RS periodically for measurement, wherein the first RS is transmitted at multiple occasions (or timings) in each period on different beams. The method also includes the cell, TP, or TRP transmitting a second RS to a UE for PDCCH demodulation, wherein the second RS is transmitted on multiple beams in a beam set of the UE in a subframe (or symbol) in which the PDCCH is transmitted.

Abstract: A method for a wireless communications system is disclosed. In one example, a user equipment (UE) (e.g. a mobile phone), receives an indication from a network about one or more UE beams that the UE can use for transmission or reception. The UE uses the one or more UE beams for transmission or reception. If and when a certain condition is fulfilled, for example, there is a beam tracking failure, the UE transmits or receives a specific signal via a specific UE beam. The specific UE beam is different from the one or more UE beams that were indicated by the network, and is selected by the UE.
