Abstract

Disclosed is a radio (wireless) communication system providing a radio communication service and a terminal, and an operation method of a Packet Data Convergence Protocol (PDCP) entity in a Universal Mobile Telecommunications System (UMTS), and more particularly, to an operation method of transmitting, by a transmitting side (transmitter), data blocks by including a Connection Frame Number (CFN) therein such that a receiving side (receiver) processes each of received data blocks by a reference time, as a method of providing a Circuit Switched (CS) service using a High Speed Downlink Packet Access (HSDPA) or High Speed Uplink Packet Access (HSUPA) technology.

Claims

1. A method for providing data in wireless communication system, the method comprising:

receiving at least one of service data units (SDUs) from an upper layer;

adding a header to the at least one of received service data units (SDU) to generate a protocol data unit (PDU),

wherein the header include timing information;

delivering the generated protocol data unit to a lower layer.

2. The method of claim 1, wherein the timing information is connection frame number (CFN).

3. The method of claim 1, wherein the timing information is added to a header in a packet data convergence protocol (PDCP) layer.

4. The method of claim 1, wherein the timing information is added to a header in a medium access control (MAC) layer

5. The method of claim 1, wherein the timing information is a circuit switched (CS) counter.

6. The method of claim 1, wherein the timing information is related to connection frame number (CFN).

7. The method of claim 1, wherein the data is provided in packet service (PS) or circuit service (CS).

8. The method of claim 1, wherein the upper layer is a RLC (radio link control) entity and a lower layer is a physical entity.
