Method and apparatus for transmitting and receiving common logical channel and dedicated logical channel transmissions via a high speed downlink shared channel

A Node-B for transmitting common logical channel transmission and dedicated logical channel transmission via a high speed downlink shared channel (HS-DSCH), the Node-B comprising:

• a medium access control (MAC)-hs entity for generating a MAC-hs protocol data unit (PDU) carrying at least one of a MAC-c/sh/m PDU for a common logical channel service data unit (SDU) and a MAC-d PDU for a dedicated logical channel SDU and transmitting the MAC-hs PDU to a user equipment (UE) via an HS-DSCH, the MAC-hs entity using a cell-specific HS-DSCH radio network temporary identity (H-RNTI) and one of a cell RNTI (C-RNTI) and a universal terrestrial radio access network RNTI (U-RNTI) when the UE is in a Cell_FACH state;
• and
• a physical layer for transmitting the MAC-hs PDU.

A method for transmitting common logical channel transmission and dedicated logical channel transmission via a high speed downlink shared channel (HS-DSCH), the method comprising:

• generating a medium access control (MAC)-hs protocol data unit (PDU) carrying at least one of a MAC-c/sh/m PDU for a common logical channel service data unit (SDU) and a MAC-d PDU for a dedicated logical channel SDU;
• and
• transmitting the MAC-hs PDU via an HS-DSCH, wherein a user equipment (UE)-specific HS-DSCH radio network temporary identifier (H-RNTI) is used for identifying a UE to which the MAC-d PDU is destined, and using a cell-specific H-RNTI for identifying a UE to which the MAC-c/sh/m PDU is destined.

A method for receiving at least one of common logical channel transmission and dedicated logical channel transmission via a high speed downlink shared channel (HS-DSCH), the method comprising:

• receiving a medium access control (MAC)-hs protocol data unit (PDU) via an HS-DSCH, the MAC-hs PDU carrying at least one of a MAC-c/sh/m PDU and a MAC-d PDU;
• and
• detecting whether the MAC-d PDU is destined to the UE using a UE-specific HS-DSCH radio network temporary identifier (H-RNTI) and whether the MAC-c/sh/m PDU is destined to the UE using a cell-specific H-RNTI.

A method for receiving common logical channel transmission and dedicated logical channel transmission via a high speed downlink shared channel (HS-DSCH), the method comprising:

• receiving a medium access control (MAC)-hs protocol data unit (PDU) via an HS-DSCH, the MAC-hs PDU carrying at least one of a MAC-c/shi/m PDU and a MAC-d PDU;
• and
• detecting whether the MAC-hs PDU is destined to the UE using a cell-specific HS-DSCH radio network temporary identity (H-RNTI) and one of a cell RNTI (C-RNTI) and a universal terrestrial radio access network RNTI (U-RNTI) when the UE is in a Cell_FACH state.
