Due to the directional nature of the beams in the mmW system, an approach to determine a beam that provides a desirable gain is studied. The apparatus may be a user equipment (UE). The apparatus receives, from a base station, a plurality of signals through a plurality of beams of the base station, each of the plurality of beams corresponding to a respective antenna port of a plurality of antenna ports of the base station, where the plurality of signals include a plurality of beam reference signals, a plurality of beam refinement reference signals, a plurality of channel state information reference signals (CSI-RSs), or a combination thereof. The apparatus performs channel estimation for each beam of the plurality of beams whose information is to be fed back Number of beame from the plurality of antenna ports based on the plurality of signals. 1102 1112 Signals (BRSs/BRASs'(S1.113s) 1114 Signals (BRSVBRASs/C211.16SM 1118 Signals (BRSO3RRSa/CSIASs) 1120 W O 20 17 / 18 430 2 Al 1122., Date mine M ba ds for N b ams 1124 Feedback Information 1128 DL communi6atio FIG. 11 Select beam fo Di. sea doling [Continued on next page] WO 2017/184302 Al MIDEDIMOHIMIRMEMOMMEINIMiliEVOIMIE EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
