Abstract

A user equipment (UE) and an operating method of the UE in a communication system are provided. The method includes establishing a first connection with a first cell using a first access technology; transmitting, through the first cell via the first connection, capability information on data communication with a second cell using a second access technology, which is different from the first access technology; receiving first data through the first cell via the first connection; receiving configuration information related to the second cell through the first cell via the first connection; establishing a second connection with the second cell using the second access technology; and receiving second data through the second cell via the second connection, while the first data is received through the first cell.

Claims

1. A method of a user equipment (UE) in a communication system, the method comprising:

establishing a first connection with a first cell using a first access technology;

transmitting, through the first cell via the first connection, capability information on data communication with a second cell using a second access technology, which is different from the first access technology;

receiving first data through the first cell via the first connection;

receiving configuration information related to the second cell through the first cell via the first connection;

establishing a second connection with the second cell using the second access technology; and

receiving second data through the second cell via the second connection, while the first data is received through the first cell.

2. The method of claim 1, wherein the first cell and the second cell are simultaneously active for the UE.

3. The method of claim 1, wherein the capability information indicates that the UE supports an operation to receive data through the first cell and the second cell.

4. A user equipment (UE) in a communication system, the UE comprising:

a memory; and

at least one processor coupled to the memory,

wherein the at least one processor is configured to;

establish a first connection with a first cell using a first access technology,

transmit, through the first cell via the first connection, capability information on data communication with a second cell using a second access technology, which is different from the first access technology,

receive first data through the first cell via the first connection,

receive configuration information related to the second cell through the first cell via the first connection,

establish a second connection with the second cell using the second access technology, and

receive second data through the second cell via the second connection, while the first data is received through the first cell.

5. The UE of claim 4, wherein the first cell and the second cell are simultaneously active for the UE.

6. The UE of claim 4, wherein the capability information indicates that the UE supports an operation to receive data through the first cell and the second cell.
