MEDIUM ACCESS CONTROL LAYER ARCHITECTURE FOR SUPPORTING ENHANCED UPLINK |
摘要 |
A method and apparatus for processing enhanced uplink data is disclosed. A request for uplink resources is transmitted, wherein the request for uplink resources is a request to transmit data over an enhanced dedicated channel (E-DCH). An uplink scheduling grant is received in response to the request for uplink resources. Data from medium access control for dedicated channel (MAC-d) flows is multiplexed into a medium access control for enhanced uplink (MAC-e) protocol data unit (PDU). A transport format combination (TFC) is selected for transmission of the MAC-e PDU. The MAC-e PDU is transmitted over the E-DCH using an identified hybrid automatic repeat request (H-ARQ) process. Feedback information is received in response to the transmitted MAC-e PDU. The MAC-e PDU is retransmitted using the identified H-ARQ process on a condition that the feedback information indicates a negative acknowledgment (NACK) of the MAC-e PDU transmission. |
