Due to the directional nature of the beams in the mmW system, an approach to determine a beam that 1104 provides a desirable gain is studied. The apparatus may be a user equip- 1112 ment (UE). The apparatus receives, from a base station, a plurality of sig- Ignals(8888 , 1112128e/C81-R8s) Spnbol 0 nals 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 an- tenna ports of the base station. The apparatus performs channel estimation for each beam of the plurality of beams from the plurality of antenna ports based on the plurality of signals. The apparatus transmits, to the base sta- tion, a feedback signal including information about one or more beams se- whose iiaformation Is to be fal back xlmbei of barns lected from the plurality of beams, the feedback signal further including one or more candidate uplink precoders. 1100 1122., 1102 1118 Signets (FIRSWBRRS•/C81-123s) 1114 Signals (BRSs/BRRSVCSIRSs) Symbol I 4 Symbol 13 Dete mine M bat ds for N b ams 1124 Feedback Information 6 W O 20 17 / 18 430 4 Al Select beam fo DL seb &Jib 1128 DL communicati n FIG. 11 [Continued on next page] WO 2017/184304 Al MIDEDIMOMOIDEIROIDEMOMMMOIMIIIIMEMOVOIS GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, 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).
