Abstract:
A WTRU may receive downlink control information (DCI) from a first transmission/reception (TRP). The DCI may indicate that the WTRU is to transmit a physical random access channel (PRACH) transmission. The DCI may include an indication of a preamble, an indication of a first PRACH mask, and/or an indication associated with a first synchronization signal block (SSB), and/or an indication of a reference signal (RS). The WTRU may be configured to transmit the preamble, to a second TRP, the preamble in a first PRACH resource. The first TRP and/or the second TRP may be associated with a same physical cell identity (PCI). The WTRU may receive, from the second TRP, a first response to the preamble. The first response may include a first timing advance (TA) command for the second timing alignment for transmission to the second TRP and/or an index indicating the second TRP.
