1. A base station (BS), comprising:
a processor configured to determine, based on a wide-beam (WB) alignment procedure, a subset of beams for transmission of physical downlink shared channels (PDSCHs); and
a transceiver operably coupled to the processor, the transceiver configured to:
transmit a physical downlink control channel (PDCCH) indicating the subset of beams, and
transmit the PDSCHs on the subset of beams, respectively, using a joint phase-time array (JPTA) beamforming,
wherein same data is included in each of the PDSCHs.
