A medium access control (MAC) layer architecture and functionality for supporting enhanced uplink (EU). A MAC entity for EU, (i.e., a MAC-e entity), (120, 220, 320) is incorporated into a wireless transmit/receive unit (WTRU) (100), a Node-B (200) and a radio network controller (RNC) (300), respectively. The WTRU MAC-e entity (120) handles hybrid-automatic repeat request (H-ARQ) transmissions and retransmissions, priority handling, MAC-e multiplexing, and transport format combination (TFC) selection. The Node-B MAC-e entity (220) handles H-ARQ transmissions and retransmissions, E-DCH (102) scheduling and MAC-e de-multiplexing. The RNC MAC-e entity (320) provides insequence delivery and handles combining of data from different Node-Bs. |
