Rate matching for layer 1 (L1) or layer 2 (L2) mobility protocol

A method for wireless communication by a base station, (BS) comprising:

• transmitting, to a user equipment (UE), an indication of a rule to be used for determining a configuration for rate matching around unavailable resources of a channel, the channel to be transmitted via one or more cells associated with one or more selected PCIs of a group of PCIs configured using lower layer signaling to serve the UE;
• transmitting, via a cell associated with a PCI of the one or more selected PCIs, an indication scheduling resources for the channel;
• transmitting signaling indicating resources allocated for synchronization signal block (SSB)transmissions for the group of PCIs, wherein the indication of the rule comprises an indication that at least a portion of the resources of the channel that are overlapping with at least one of the SSB transmissions via the cell scheduling the resources for the channel are the unavailable resources, and that the resources for the channel are non-overlapping with SSB transmissions for one or more other PCIs of the group of PCIs;
• generating the channel in accordance with the configuration for rate matching;
• and
• transmitting the channel to the UE.

An apparatus for wireless communication by a user equipment (UE), comprising:

• memory;
• and
• one or more processors coupled to the memory, the one or more processors being configured, individually or collectively, to:
• receive lower layer signaling indicating one or more selected physical cell identifiers (PCIs) of a group of PCIs for the UE;
• receive an indication of a rule to be used for determining a configuration for rate matching around unavailable resources of a channel to be received via one or more cells associated with the one or more selected PCIs;
• receive, via a cell associated with a PCI of the one or more selected PCIs, an indication scheduling resources for the channel;
• receive signaling indicating resources allocated for synchronization signal block (SSB)transmissions for the group of PCIs, wherein the indication of the rule comprises an indication that at least a portion of the resources of the channel that are overlapping with at least one of the SSB transmissions via the cell scheduling the resources for the channel are the unavailable resources, and that the resources for the channel are non-overlapping with synchronization signal block (SSB) transmissions for one or more other PCIs of the group of PCIs;
• determine the configuration for the rate matching based on the rule by determining to rate match around the unavailable resources or the resources overlapping with the at least one of the SSB transmissions via the cell;
• and
• receive the channel via the one or more cells in accordance with the determination.
