Techniques for configuring search spaces in multicast/broadcast service (MBS) wireless communications

A method for wireless communication, comprising:

• generating a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs);
• indicating a priority of the one or more search spaces for detecting a control channel, at least in part by including in a control resource set (CORESET) configuration an indication that the one or more search spaces correspond to a multicast/broadcast service (MBS) CORESET, to at least one of:
• prioritize the one or more search spaces over other defined search spaces for detecting control information over the control channel;
• or
• prioritize, in the one or more search spaces, one or more control information formats over other control information formats of control information for detecting the control information over the control channel;
• and
• transmitting the search space configuration to the group of one or more UEs.

An apparatus for wireless communication, comprising:

• a transceiver;
• a memory configured to store instructions;
• and one or more processors communicatively coupled with the memory and the transceiver, wherein the one or more processors are configured to:
• receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs);
• determine, based on one or more search spaces corresponding to a multicast/broadcast service (MBS) control resource set (CORESET) for MBS communications that is indicated in a CORESET configuration, a priority for detecting control information transmitted over a control channel based on the one or more search spaces, wherein determining the priority comprises at least one of:
• prioritizing the one or more search spaces over other defined search spaces for detecting the control information over the control channel;
• or prioritizing, in the one or more search spaces, one or more control information formats over other control information formats of control information for detecting the control information over the control channel;
• and
• perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.
