Classification: CPC H | IPC H

Claim 7:
8. A user equipment (UE), comprising:
a transceiver configured to simultaneously connect with a first next generation node B (gNB) and at least one second gNB over a same carrier in a multiple transmission and reception point (multi-TRP) configuration; and
a processor configured to:
divide uplink (UL) resources into a plurality of groups, and
determine a spatial relation and a pathloss reference signal (RS) for each one of the plurality of groups based on a transmission configuration indication (TCI) indicating a quasi-co-location (QCL) source RS for a downlink channel wherein, the processor is further configured to, when the spatial relation and the pathloss RS for the UL resources is not configured for group x in the plurality of groups, determine a default spatial relation and a default pathloss RS for the UL resources based on at least a reference signal in a TCI state for a control resource set (CORESET) with a lowest ID in an active bandwidth part (BWP) on the same component carrier (CC) with a CORESET pool index set to y, wherein a mapping between x and y is either one of configured by higher layer signaling or predefined,
wherein the transceiver is further configured to transmit UL data on the UL resources corresponding to each one of the plurality of groups to a respective one of the first gNB or the at least one second gNB.
