Coverage enhancement for dual connectivity

An apparatus for wireless communication, comprising:

• a processor;
• a memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit a threshold value to a user equipment (UE);
• receive, from the user equipment (UE), a radio link control (RLC) status report, a size of the RLC status report being greater than the threshold value, wherein the RLC status report indicates a status of data transmitted by a base station to the UE via a first communication link, and the RLC status report is received via a second communication link;
• and
• forward, to the base station, the RLC status report via a backhaul link.

A method for wireless communication at a user equipment (UE), comprising:

• attempting to receive, from a first base station, data via a first communication link;
• generating a radio link control (RLC) status report indicating a status of the data at the UE;
• receiving a threshold value;
• determining a size of the RLC status report is greater than the threshold value;
• and
• transmitting, to a second base station, the RLC status report via a second communication link.

A method for wireless communication at a first base station, comprising:

• transmitting a threshold value to a user equipment (UE);
• receiving, from the user equipment (UE), a radio link control (RLC) status report, a size of the RLC status report being greater than the threshold value, wherein the RLC status report indicates a status of data transmitted by a second base station to the UE via a first communication link, and the RLC status report is received via a second communication link;
• and
• forwarding, to the second base station, the RLC status report via a backhaul link.
