1. A method for a user equipment (UE) operating in a wireless communication system comprising a first base station (BS) and a second BS, the method comprising:
- receiving, by the UE, a single threshold value for an uplink data split operation; and
reporting, by the UE, buffer status information for the uplink data split operation based on an amount of an uplink data available for transmission,wherein the amount of the uplink data available for transmission comprises at least one of Packet Data Convergence Protocol (PDCP) data available for transmission or Radio Link Control (RLC) data available for transmission, andwherein, based on the received single threshold value, (i) the PDCP data available for transmission is indicated to a first Medium Access Control (MAC) entity of the UE for the first BS, and (ii) the PDCP data available for transmission as “
0”
is indicated to a second MAC entity of the UE for the second BS.

Abstract
A method for a base station (BS) operating in a wireless communication system, the method includes transmitting, to a user equipment (UE), first information indicating a threshold value for an uplink data split operation; and receiving a buffer status report (BSR) from the UE, wherein a value of a buffer size in the BSR is determined based on second information that indicates an amount of data available for transmission for a packet data convergence protocol (PDCP) entity of the UE when the amount of the data available for transmission is larger than the threshold value.

6. A user equipment (UE) configured to operate in a wireless communication system comprising a first base station (BS) and a second BS, the UE comprising:
-
a transmitter and a receiver; at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising; receiving, through the receiver, a single threshold value for an uplink data split operation, and transmitting, through the transmitter, buffer status information for the uplink data split operation based on an amount of an uplink data available for transmission, wherein the amount of the uplink data available for transmission comprises at least one of Packet Data Convergence Protocol (PDCP) data available for transmission or Radio Link Control (RLC) data available for transmission, and wherein, based on the received single threshold value, (i) the PDCP data available for transmission is indicated to a first Medium Access Control (MAC) entity of the UE for the first BS, and (ii) the PDCP data available for transmission as “
0”
is indicated to a second MAC entity of the UE for the second BS. - View Dependent Claims (7, 8, 9, 10)

11. An apparatus configured to control a user equipment (UE) to operate in a wireless communication system, the apparatus comprising:
-
at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising; receiving a single threshold value for an uplink data split operation, and transmitting buffer status information for the uplink data split operation based on an amount of an uplink data available for transmission, wherein the amount of the uplink data available for transmission comprises at least one of Packet Data Convergence Protocol (PDCP) data available for transmission or Radio Link Control (RLC) data available for transmission, and wherein, based on the received single threshold value, (i) the PDCP data available for transmission is indicated to a first Medium Access Control (MAC) entity of the UE for a first base station (BS), and (ii) the PDCP data available for transmission as “
0”
is indicated to a second MAC entity of the UE for a second BS. - View Dependent Claims (12, 13, 14, 15)
