Split-Bearer Enhancements for Dual Connectivity

A hosting base station, comprising:

• at least one antenna;
• at least one radio in communication with the at least one antenna and configured to communicate according to at least one radio access technology (RAT);
• and
• one or more processors in communication with the at least one radio and configured to cause the base station to:
• set up a split-bearer for a user equipment (UE) device connected to at least two cell groups (CGs) supported by the hosting base station and one or more corresponding base stations, including a ratio of a split of data to be delivered to the UE via the hosting base station and data to be delivered to the UE via the one or more corresponding base stations;
• transmit, based on the ratio of the split, a first portion of the data to the UE via a connection with the UE and a second portion of the data to the one or more corresponding base stations via a connection with the one or more corresponding base stations to be sent to the UE;
• and
• adjust, based at least in part on one or more split-bearer quality reports received from the UE, the ratio of the split.

An apparatus, comprising:

• a memory;
• and
• one or more processors in communication with the memory and configured to:
• set up a split-bearer for a user equipment (UE) device connected to at least two cell groups (CGs) supported by a hosting base station and one or more corresponding base stations, including a ratio of a split of data to be delivered to the UE via the hosting base station and data to be delivered to the UE via the one or more corresponding base stations;
• transmit, based on the ratio of the split, a first portion of the data to UE via a connection with the UE and a second portion of the data to the one or more corresponding base stations via a connection with the one or more corresponding base stations to be sent to the UE;
• and
• adjust, based at least in part on one or more split-bearer quality reports received from the UE, the ratio of the split.
