    Abstract: Performing a UE-triggered lower layer-based handover may include performing measurements of source gNB CSI-RS samples associated with a source gNB. Measurements of target gNB CSI-RS samples associated with a target gNB may be performed, wherein the CSI-RS samples associated with the source gNB and the CSI-RS samples associated with the target gNB are transmitted in a burst structure. A subset of the source gNB CSI-RS samples and the target gNB CSI-RS samples may be filtered using a layer 1 or a layer 2 filter. A filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples may be generated. Based on the generated filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples, determining whether a handover from the source gNB to the target gNB is to occur.

    Abstract: 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. The UE divides uplink (UL) resources into a plurality of groups, determines 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 and transmits 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.

    Abstract: Various user equipment (UE) operations performed when the UE is in multiple Downlink Control Information (multi-DCI) based multiple transmission and reception point (multi-TRP) configuration. The operations receiving, from one of the first or second gNBs, one or more cell reference signal (CRS) rate matching patterns, wherein the one or more CRS rate matching patterns comprise an indication of a control resource set (CORESET) pool for each of the one or more CRS rate matching patterns and applying the one or more CRS rate matching patterns to a CORESET for a Physical Downlink Shared Channel (PDSCH) based on the indication of the CORESET pool.
