METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING COMMON LOGICAL CHANNEL AND DEDICATED LOGICAL CHANNEL TRANSMISSIONS VIA A HIGH SPEED DOWNLINK SHARED CHANNEL

摘要

A method and apparatus for transmitting and receiving common logical chan nel and dedicated logical channel transmissions via a high speed downlink sh ared channel (HS-DSCH) are disclosed. A medium access control (MAC)-hs entit y generates a MAC-hs protocol data unit (PDU) carrying a MAC-c/sh/m PDU and/ or a MAC-d PDU. A UE-specific HS-DSCH radio network temporary identifier (H- RNTI) may be used for the MAC-d PDU, and a cell-specific H-RNTI may be used for the MAC-c/sh/b PDU. Alternatively, a cell-specific H-RNTI and one of a c ell RNTI (C-RNTI) and a universal terrestrial radio access network RNTI (U-R NTI) may be used in a Cell_FACH state. The logical channel type and identity may be inserted in a MAC-hs PDU header or indicated by a distinct H-RNTI. A logical channel type for common logical channels may be identified in a MAC -c/sh/m PDU header. The logical channel type and identity may be identified by a queue identity.
