Downlink shared channel configuration for multicast

An apparatus for wireless communications, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a group-specific multicast/broadcast communication configuration for receiving one or more multicast/broadcast downlink signals, wherein the group-specific multicast/broadcast communication configuration is independently configured from a unicast communication configuration and a cell-specific communication configuration;
• determine a plurality of multicast/broadcast communication parameters based at least in part on the group-specific multicast/broadcast communication configuration, the plurality of multicast/broadcast communication parameters including a time resource allocation, a frequency resource allocation, a slot configuration, a downlink reference signal configuration, and a resource mapping configuration for receiving the one or more multicast/broadcast downlink signals;
• and
• receive the one or more multicast/broadcast downlink signals based at least in part on the plurality of multicast/broadcast communication parameters including the time resource allocation, the frequency resource allocation, the slot configuration, the downlink reference signal configuration, and the resource mapping configuration.

A non-transitory computer-readable medium storing code for wireless communications at a user equipment (UE), the code comprising instructions executable by a processor to:

• identify a group-specific multicast/broadcast communication configuration for receiving one or more multicast/broadcast downlink signals, wherein the group-specific multicast/broadcast communication configuration is independently configured from a unicast communication configuration and a cell-specific communication configuration;
• determine a plurality of multicast/broadcast communication parameters based at least in part on the group-specific multicast/broadcast communication configuration, the plurality of multicast/broadcast communication parameters including a time resource allocation, a frequency resource allocation, a slot configuration, a downlink reference signal configuration, and a resource mapping configuration for receiving the one or more multicast/broadcast downlink signals;
• and
• receive the one or more multicast/broadcast downlink signals based at least in part on the plurality of multicast/broadcast communication parameters including the time resource allocation, the frequency resource allocation, the slot configuration, the downlink reference signal configuration, and the resource mapping configuration.
