Abstract

A method and apparatus of a base station (P-ENB) that controls a primary cell (PCell) of user equipment (UE) is provided. The method includes 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.

Claims

1. A communication method of an evolved Node B of controlling a primary cell (P-ENB) of a User Equipment (UE), the method comprising:

receiving a packet from a serving gateway through a non-primary Evolved Packet System (NP-EPS) bearer for serving cells of an eNB (NP-ENB) other than the P-eNB;

generating a first Radio Link Control Packet Data Unit (RLC PDU) using the received packet; and

transmitting the first RLC PDU to the NP-ENB.

2. The method of claim 1, further comprising:

receiving a MAC Service Data Unit (SDU) from the NP-ENB;

generating a second RLC PDU corresponding to the MAC SDU; and

transmitting the second RLC PDU, which is converted, to the serving gateway through the NP-EPS bearer.

3. A communication method of a non-primary evolved node B (NP-ENB) other than a primary eNB (P-ENB) controlling a primary cell (PCell) of a User Equipment (UE), the method comprising:

receiving a Radio Link Control Packet Data Unit (RLC PDU) from the P-ENB;

re-segmenting the RLC PDU into re-segmented RLC PDUs; and

transmitting the re-segmented RLC PDUs, which are converted to signals, to the UE.

4. The method of claim 3, further comprising:

receiving a signal from the UE;

generating a Media Access Control Service Data Unit (MAC SDU) using the signal; and

transmitting the MAC SDU to the P-ENB.

5. A communication apparatus of a primary evolved node B (P-ENB) controlling a primary cell (PCell) of user equipment (UE), the apparatus comprising:

a communication unit which receives a packet from a serving gateway through a non-primary Evolved Packet System (NP-EPS) bearer for serving cells of an eNB (NP-ENB) other than the P-eNB; and

a control unit which generates a first Radio Link Control Packet Data Unit (RLC PDU) using the received packet,

wherein the communication unit transmits the first RLC PDU to the NP-ENB.

6. The apparatus of claim 5, wherein the communication unit receives a MAC Service Data Unit (SDU) from the NP-ENB, the control unit generates a second RLC PDU corresponding to the MAC SDU, and the communication unit transmits the second RLC PDU, which is converted, to the serving gateway through the NP-EPS bearer.

7. A communication apparatus of a non-primary evolved node B (NP-ENB) other than a primary eNB (P-ENB) controlling a primary cell (PCell) of a User Equipment (UE), the apparatus comprising:

a communication unit which receives a Radio Link Control Packet Data Unit (RLC PDU) from the P-ENB; and

a control unit which re-segments the RLC PDU into re-segmented RLC PDUs,

the communication unit transmits the re-segmented RLC PDUs, which are converted to signals, to the UE.

8. The apparatus of claim 7, wherein the communication unit receives a signal from the UE, the control unit generates a Media Access Control Service Data Unit (MAC SDU) using the signal, and the communication unit transmits the MAC SDU to the P-ENB.
