A method for wireless communication at a user equipment, UE, comprising: transmitting (2305; 2405; 2505) a capability message to the base station indicating a multi-connectivity capability of the UE to support more than two concurrent active cell group connections; transmitting (2310; 2410; 2510), to a base station, one or more measurement reports that provide measurement information for cells in proximity to the UE; receiving (2315; 2415; 2515), responsive to the capability message and the one or more measurement reports, a multi-connectivity configuration, the multi-connectivity configuration comprises a cell group set that includes a plurality of cell groups with which the UE is configured for multi-connectivity communications, the cell group set including more than two active cell groups to which the UE is connected for concurrent connected mode operations between the UE and the base station; receiving an indication of which cell groups of the more than two active cell groups are to be configured for packet data convergence protocol, PDCP, aggregation such that data associated with a data radio bearer, DRB, having a throughput requirement above at least one threshold is distributed across the indicated cell groups having an aggregate throughput that satisfies the throughput requirement of the DRB; and communicating (2320; 2425; 2525) with the base station via the more than two active cell groups in accordance with the multi-connectivity configuration each of the plurality of cell groups of the cell group set includes a set of cells configured for a same distributed unit, DU, of the base station and managed by a single medium access control, MAC, entity, and wherein all of the plurality of cell groups of the cell group set are associated with a same central unit, CU, of the base station. transmitting (2305; 2405; 2505) a capability message to the base station indicating a multi-connectivity capability of the UE to support more than two concurrent active cell group connections; transmitting (2310; 2410; 2510), to a base station, one or more measurement reports that provide measurement information for cells in proximity to the UE; receiving (2315; 2415; 2515), responsive to the capability message and the one or more measurement reports, a multi-connectivity configuration, the multi-connectivity configuration comprises a cell group set that includes a plurality of cell groups with which the UE is configured for multi-connectivity communications, the cell group set including more than two active cell groups to which the UE is connected for concurrent connected mode operations between the UE and the base station; receiving an indication of which cell groups of the more than two active cell groups are to be configured for packet data convergence protocol, PDCP, aggregation such that data associated with a data radio bearer, DRB, having a throughput requirement above at least one threshold is distributed across the indicated cell groups having an aggregate throughput that satisfies the throughput requirement of the DRB; and communicating (2320; 2425; 2525) with the base station via the more than two active cell groups in accordance with the multi-connectivity configuration each of the plurality of cell groups of the cell group set includes a set of cells configured for a same distributed unit, DU, of the base station and managed by a single medium access control, MAC, entity, and wherein all of the plurality of cell groups of the cell group set are associated with a same central unit, CU, of the base station. <EOS>
