MIMO enhancement capability design
Apparatuses, systems, and methods for multi-TRP by a UE, including out of order delivery of PDSCH, PUSCH, and/or DL ACK/NACK. The UE may receive, from a base station, a configuration that may include multiple control resource set (CORESET) pools and each CORESET pool may be associated with an index value. The UE may determine that at least two DCIs of the multiple DCIs end at a common symbol and determine, based on one or more predetermined rules, when the UE may be scheduled to receive PDSCHs, transmit PUSCHs, and/or transmit ACK/NACKs from CORESETs associated with the at least two DCIs.

receiving a second PDCCH of the one or more PDCCHs ending at a second symbol later than the first symbol; and

9. The non-transitory computer readable memory medium of claim 6 ,
wherein the program instructions are further executable by the processor to cause the device to:
monitor, for each CORESET pool of the one or more CORESET pools, one unicast downlink transmission and one unicast uplink transmission per slot per scheduled component carrier per CORESET pool.
10. The non-transitory computer readable memory medium of claim 6 ,
