Physical downlink control channel transmissions for multicast/broadcast system services

A method of wireless communication performed by a user equipment (UE), comprising:

• monitoring a search space associated with a physical downlink control channel (PDCCH) corresponding to a multicast/broadcast system (MBS) physical downlink shared channel (PDSCH) for at least one MBS PDCCH communication having a payload that is scrambled according to a PDCCH payload scrambling sequence based on a value of a radio network temporary identifier (RNTI), wherein the value of the RNTI is equal to zero;
• and
• receiving the at least one MBS PDCCH communication.

A method of wireless communication performed by a network node, comprising:

• transmitting a multicast/broadcast system (MBS) configuration that indicates a physical downlink control channel (PDCCH) payload scrambling sequence based on a value of a radio network temporary identifier (RNTI) for a search space associated with a PDCCH corresponding to an MBS physical downlink shared channel (PDSCH), wherein the value of the RNTI is equal to zero;
• and
• transmitting at least one MBS PDCCH communication based at least in part on the configuration.
