Claim 0:
1. A method, comprising:
at a user equipment (UE) in a multiple transmission and reception point (multi-TRP) configuration having simultaneous connections with a first next generation node B (gNB) and at least one second gNB over a same carrier:
dividing uplink (UL) resources into a plurality of groups;
determining 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, when the spatial relation and the pathloss RS for the UL resources is not configured for group x in the plurality of groups, a default spatial relation and a default pathloss RS for the UL resources is based on 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; and
transmitting 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.
