Abstract: A user equipment (UE) can process signals including a first synchronization signal (SS) and a second SS. The first SS and the second SS are beamformed with transmit beams and transmitted on subbands in a first set of symbols, for the first SS, and a second set of symbols, for the second SS. The UE can detect the first SS in the first set of symbols, and measure beam qualities of the transmit beams on the subbands in at least one of the first set of symbols or the second set of symbols. The UE can select one or more transmit beams and corresponding one or more subbands based on the measured beam qualities. The UE can detect the second SS on the selected subbands in the second set of symbol, and each of subbands in the first and second sets of symbols is associated with a transmit beam.

Abstract: A wireless device, comprising: a hybrid antenna array configured to receive a signal transmitted by another wireless device over a wireless channel; and a transceiver configured to update analog radio frequency precoders of a hierarchical codebook based on magnitudes of multipath components of the wireless channel.
