Abstract

A method for transmitting downlink data to a mobile terminal is disclosed. The mobile terminal receives a particular common H-RNTI (HS-DSCH Radio Network Identifier) via an HS-SCCH (High Speed-Shared Control Channel) associated with an HS-DSCH (High Speed-Downlink Shared Channel), recognizes whether a header of a MAC (Medium Access Control) PDU (Packet Data Unit) transmitted by the HS-DSCH includes a terminal-exclusive identifier, acquires the terminal-exclusive identifier, and processes the MAC PDU as its own if the acquired terminal-exclusive identifier is intended for the terminal itself.

Claims

1. A method for receiving data by a terminal in a wireless communication system, the method comprising:

receiving, by the terminal, a common H-RNTI (HS-DSCH (High Speed Downlink Shared Channel) Radio Network Temporary Identifier) via an HS-SCCH (High Speed Shared Control Channel);

receiving, by the terminal, a MAC (Medium Access Control) PDU (Protocol Data Unit) via an HS-DSCH (High Speed Downlink Shared Channel), the HS-DSCH being associated with the HS-SCCH, the MAC PDU including a MAC-hs (MAC-High Speed) header, a MAC-c (MAC Common) header and a MAC SDU (Service Data Unit) in order; and

transferring the MAC SDU to an upper layer if the terminal is indicated by a U-RNTI (UTRAN Radio Network Temporary Identifier) included in the MAC-c header,

wherein the U-RNTI is only included in the MAC-c header.

2. The method of claim 1, wherein the common H-RNTI is shared by a plurality of terminals.

3. The method of claim 1, wherein the MAC SDU is transferred to the upper layer through a dedicated control channel (DCCH) or a dedicated traffic channel (DTCH).

4. A terminal comprising:

a receiving unit configured to receive a common H-RNTI (HS-DSCH (High Speed Downlink Shared Channel) Radio Network Temporary Identifier) via an HS-SCCH (High Speed Shared Control Channel), and to receive, a MAC (Medium Access Control) PDU (Protocol Data Unit) via an HS-DSCH (High Speed Downlink Shared Channel), the HS-DSCH being associated with the HS-SCCH, the MAC PDU including a MAC-hs (MAC-High Speed) header, a MAC-c (MAC Common) header and a MAC SDU (Service Data Unit) in order; and

a processing unit configured to transfer the MAC SDU to an upper layer if the terminal is indicated by a U-RNTI (UTRAN Radio Network Temporary Identifier) included in the MAC-c header,

wherein the U-RNTI is only included in the MAC-c header.

5. The terminal of claim 4, wherein the common H-RNTI is shared by a plurality of terminals.

6. The terminal of claim 4, wherein the MAC SDU is transferred to the upper layer through a dedicated control channel (DCCH) or a dedicated traffic channel (DTCH).

7. A method for transmitting data by a network to a terminal in a wireless communication system, the method comprising:

transmitting a common H-RNTI (HS-DSCH (High Speed Downlink Shared Channel) Radio Network Temporary Identifier) to the terminal via an HS-SCCH (High Speed Shared Control Channel);

generating a MAC (Medium Access Control) PDU (Protocol Data Unit) including a MAC-hs (MAC-High Speed) header, a MAC-c (MAC Common) header and a MAC SDU (Service Data Unit) in order; and

transmitting the generated MAC PDU to the terminal via an HS-DSCH (High Speed Downlink Shared Channel), the HS-DSCH being associated with the HS-SCCH,

wherein a U-RNTI (UTRAN Radio Network Temporary Identifier) is only included in the MAC-c header.

8. The method of claim 7, wherein the common H-RNTI is shared by a plurality of terminals.

9. The method of claim 7, wherein the MAC SDU is for a dedicated control channel (DCCH) or a dedicated traffic channel (DTCH).
