Synchronization signal block transmission using spatial division multiplexing

An apparatus for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive, during a connected mode or an idle mode and from a network entity, signaling identifying spatial resources of a set of synchronization signal block communications, wherein the set of synchronization signal block communications includes two or more synchronization signal block communications, and wherein the spatial resources correspond to one or more beams;
• receive, based at least in part on the spatial resources, at least one of the set of synchronization signal block communications using spatial multiplexing corresponding to the spatial resources, wherein the set of synchronization signal block communications are each received concurrently using the spatial resources associated with the one or more beams in a beam sweeping transmission;
• and
• determine, based at least in part on receiving the at least one of the set of synchronization signal block communications, a set of channel measurements.

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

• identifying, during a connected mode or an idle mode of a user equipment, a set of synchronization signal block communications, wherein the set of synchronization signal block communications includes two or more synchronization signal block communications;
• transmitting, to the user equipment, signaling identifying spatial resources of the set of synchronization signal block communications, wherein the spatial resources correspond to one or more beams;
• and
• transmitting, based at least in part on the spatial resources, the set of synchronization signal block communications using spatial multiplexing, wherein the set of synchronization signal block communications are each transmitted concurrently using the spatial resources associated with the one or more beams in a beam sweeping transmission.
