SOFT BUFFER SIZE DETERMINATION METHOD FOR DUAL CONNECTIVITY
First Claim
1. A method of a terminal for receiving downlink data in communication system supporting dual connectivity, the method comprising:
- receiving the downlink data from a base station;
determining whether the terminal is configured with a secondary cell group (SCG);
determining, if the terminal is configured with the SCG, a size of a soft buffer per code block per cell based on a number of configured serving cells of the terminal; and
storing the received downlink data in the soft buffer based on the size of the soft buffer per code block per cell,wherein the configured serving cells are included in a master cell group (MCG) and the SCG.

Abstract
A method for a dual connectivity-enabled terminal which receives downlink data from at least one of a macro and a pico base station to transmit uplink control information corresponding to downlink data is provided. The method includes receiving the downlink data from a base station, determining whether the terminal is configured with a secondary cell group (SCG), determining, if the terminal is configured with the SCG, a size of a soft buffer per code block per cell based on a number of configured serving cells of the terminal, and storing the received downlink data in the soft buffer based on the size of the soft buffer per code block per cell, wherein the configured serving cells are included in a master cell group (MCG) and the SCG.
