摘要:
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), is incorporated into a wireless transmit/receive unit (WTRU), a Node-B and a radio network controller (RNC). The WTRU MAC-e 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 handles H-ARQ transmissions and retransmissions, E-DCH scheduling and MAC-e de-multiplexing. The RNC MAC-e entity provides in-sequence delivery and handles combining of data from different Node-Bs.
摘要:
A wireless transmit/receive unit, WTRU, and a method for use by a WTRU for uplink transmission, are disclosed. The WTRU transmits, to a Node-B, a first type message, a second type message, and a third type message, wherein the first type message indicates that the WTRU has uplink buffered data available for transmission, wherein the second type message includes a plurality of indications, wherein each indication indicates an amount of uplink buffered data associated with at least one priority, and wherein the third type message indicates an amount of uplink buffered data and has less information than the second type message. The WTRU receives, from the Node-B, in response to the transmitted first type message, the transmitted second type message, or the transmitted third type message, an uplink data scheduling message, and the WTRU transmits, to the Node-B, uplink data over an uplink channel based on the received uplink data scheduling message.
摘要:
A wireless communication method and apparatus for transferring buffered enhanced uplink (EU) data from a wireless transmit/receive unit (WTRU), i.e., a mobile station, to a Node-B. The EU data is generated and stored in a buffer of the WTRU. The WTRU transmits a message to the Node-B including a request for a desired transport format combination (TFC) or data traffic indicator. The Node-B schedules one or more allowed EU data transmissions between the WTRU and the Node-B by transmitting an EU data scheduling message to the WTRU. The WTRU transmits all of the EU data stored in the buffer to the Node-B if the allowed EU data transmissions are sufficient to support transmission of all of the EU data stored in the buffer. Otherwise, the WTRU transmits a portion of the EU data along with the desired TFC or detailed traffic volume measurement (TVM) information to the Node-B.
