A method and system for determining beam reciprocity for a beam of a wireless transmit/receive unit (WTRU) are disclosed. A WTRU may determine a downlink (DL) beam for synchronization. Then, the WTRU may determine transmission reception point (TRP) transmit (TX)/receive (RX) beam correspondence information (BCI) using the determined DL beam. Further, the WTRU may determine a number of WTRU TX beams based on at least the TRP TX/RX BCI. Also, the WTRU may determine a set of WTRU TX beams based on at least the DL beam and the TRP TX/RX BCI, wherein determining the set includes determining one or more WTRU TX beam directions. In addition, the WTRU may transmit data using the determined set of WTRU TX beams. In an example, the determination of the TRP TX/RX BCI may be based on a received TRP TX/RX BCI.
