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), wherein the common H-RNTI is commonly used by a plurality of terminals, and wherein the terminal is one of the plurality of terminals;

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 first header and a MAC SDU (Service Data Unit); 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 first header,

wherein the first header is a MAC-c (MAC Common) header,

wherein the MAC PDU further includes a second header,

wherein the second header is a MAC-hs header,

wherein the MAC PDU includes the second header, the first header and the MAC SDU in order.

2. A terminal in a wireless communication system, the 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, and the MAC PDU including a first header and a MAC SDU (Service Data Unit), wherein the common H-RNTI is commonly used by a plurality of terminals, and wherein the terminal is one of the plurality of terminals; 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 first header,

wherein the first header is a MAC-c (MAC Common) header,

wherein the MAC PDU further includes a second header, and

wherein the second header is a MAC-hs header,

wherein the MAC PDU includes the second header, the first header and the MAC SDU in order.

3. 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), wherein the common H-RNTI is commonly used by a plurality of terminals, and wherein the terminal is one of the plurality of terminals;

generating a MAC (Medium Access Control) PDU (Protocol Data Unit) including a first header and a MAC SDU (Service Data Unit); and

transmitting the generated MAC PDU to the terminal via an HS-DSCH, the HS-DSCH being associated with the HS-SCCH,

wherein the first header includes a U-RNTI (UTRAN Radio Network Temporary Identifier) for indicating the terminal,

wherein the first header is a MAC-c (MAC Common) header,

wherein the MAC PDU further includes a second header, and

wherein the second header is a MAC-hs header,

wherein the MAC PDU is generated to include the second header, the first header and the MAC SDU in order.
