Abstract: A UE transmits a random access channel (RACH) preamble and a BS receives the RACH channel. The BS configures the RACH preamble to align boundaries of the RACH preamble with boundaries of OFDM symbols on which the RACH preamble is configured in the time domain. The UE generates/transmits the RACH preamble to align the boundaries of the RACH preamble with the boundaries of OFDM symbols on which the RACH preamble is configured in the time domain.

Abstract: Here, operation for 3D beam forming is disclosed. UE, receiving reference signals from one or more base stations (eNBs), may report feedback information comprising precoding matrix information to the one or more eNBs. The precoding matrix information indicates a first type precoding matrix for a horizontal direction and a second type precoding matrix for a vertical direction. eNBs may transmit signals, which are precoded based on a third type precoding matrix for beam forming both on the horizontal direction and the vertical direction.
