8. A wireless transmit/receive unit (WTRU) configured to perform a multi-transmit/receive point (multi-TRP) transmission, comprising:
a receiver configured to:
receive a first physical downlink shared channel (PDSCH) transmission from a first transmit receive point (TRP); and
receive a second PDSCH transmission from a second TRP;
a processor configured to:
decode a first physical downlink control channel (PDCCH) transmission from the first TRP to obtain a first parameter set indicating first timing information;
decode a second PDCCH transmission from a second TRP to obtain a second parameter set indicating second timing information;
for each TRP, based on each of a PDSCH reception slot location and the first timing information and the second timing information, determine a candidate PUCCH slot location; and
select a PUCCH slot location for the first and second TRP based on comparison of the determined candidate PUCCH slot locations, wherein the selected PUCCH slot location is a latest candidate PUCCH slot location in time; and;
a transmitter to transmit a PUCCH transmission to the first and second TRP using the selected PUCCH slot location.
