1. A method by a first node, the method comprises:
- transmitting, to a terminal, a message for configuring a first bearer with a second node;
receiving a first packet;
generating a packet data convergence protocol (PDCP) protocol data unit (PDU), from the first packet, with a PDCP header by a first PDCP entity of the first node; and
transmitting the PDCP PDU to the second node using the first bearer based on a GPRS Tunnel Protocol (GTP), the first bearer being configured for transmitting downlink data between the first PDCP entity of the first node and a radio link control (RLC) entity of the second node.

Abstract
The present specification relates to a communication method and apparatus. The communication method for a base station (P-ENB) that controls a primary cell (PCell) of user equipment (UE) according to one embodiment of the present specification comprises the steps of: receiving a packet from a serving gateway through a non-primary (NP)-evolved packet system (EPS) bearer for a serving cell of a non-P-ENB base station (NP-ENB); generating a first radio link control packet data unit (RLC PDU) using the received packet; and transmitting the generated first RLC PDU to the NP-ENB.
