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 scheduling a second PUSCH; and
determining that the second PUSCH starts on a symbol earlier than the last symbol of the first PUSCH when the first PDCCH and the second PDCCH are associated with different CORESET pool index values.

receive a first DCI of the one or more DCIs ending at a first symbol and scheduling a first physical uplink shared channel (PUSCH);
receive a second DCI of the one or more DCIs ending at a second symbol later than the first symbol and scheduling a second PUSCH; and

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.
11. A method, comprising:
transmitting, to a user equipment device (UE), a configuration including one or more control resource set (CORESET) pools for one or more physical downlink control channels (PDCCHs), wherein each CORESET pool is associated with an index value;
transmitting a first PDCCH of the one or more PDCCHs that ends at a first symbol and schedules a first physical uplink shared channel (PUSCH);

receiving the first PUSCH ending at a third symbol; and
receiving the second PUSCH starting at a fourth symbol occurring earlier than the third symbol.
12. The method of claim 11 , further comprising:
receiving, from the UE, an indication that two pre-coding matrix index (PMI) sub-bands per channel quality indicator (CQI) sub-band for less than twenty PMI sub-bands is not supported.
13. The method of claim 11 ,
wherein, in a common slot, for a physical downlink shared channel (PDSCH) scheduled by a CORESET pool of the one or more CORESET pools, acknowledgements/negative acknowledgements (ACK/NACKs) can have any time relationship.
14. The method of claim 11 ,
wherein, in a common slot, for a physical downlink shared channel (PDSCH) scheduled by a CORESET pool of the one or more CORESET pools, a CORESET pool having a non-zero index value cannot schedule an acknowledgements/negative acknowledgements (ACK/NACKs) earlier than a slot scheduled by a CORESET pool having an index value of 0.
15. The method of claim 11 , further comprising:
transmitting, for multi-TRP multi-DCI based ultra reliable low latency communication (URLLC), multiple PDSCHs with a common HARQ ID overlapping in time.
16. An apparatus, comprising:
