Claim of US Patent No. 10,251,171

1. A method for a user equipment (UE) operating in a wireless communication system, the method comprising:configuring a Packet Data Convergence Protocol (PDCP) entity, two Radio Link Control (RLC) entities and two Medium Access Control (MAC) entities associated with a split bearer,
wherein a first RLC entity is associated with a first MAC entity, and a second RLC entity is associated with a second MAC entity, and
wherein the first MAC entity is for a first evolved-Node B (eNB) and the second MAC entity is for a second eNB;
when data becomes available for transmission in the PDCP entity, indicating, to the first MAC entity and to the second MAC entity, an amount of data for transmission in the PDCP entity, the amount of data for transmission including data that is common to the first MAC entity and the second MAC entity,
wherein an amount of data for transmission in the first RLC entity indicated to the first MAC entity and an amount of data for transmission in the second RLC entity indicated to the second MAC entity are not common;
generating a first buffer status reporting (BSR) for the first eNB with considering the indicated amount of data available for transmission in the PDCP entity and the indicated amount of data available for transmission in the first RLC entity;
generating a second BSR for the second eNB with considering the indicated amount of data available for transmission in the PDCP entity and the indicated amount of data available for transmission in the second RLC entity;
transmitting, via the first MAC entity, the first BSR to the first eNB; and
transmitting, via the second MAC entity, the second BSR to the second eNB.
