METHOD AND APPARATUS FOR REPORTING BUFFER STATUS

摘要

PROBLEM TO BE SOLVED: To enable a wireless transmit/receive unit (WTRU) to report a buffer status as part of scheduling information for enhanced dedicated channel (E-DCH) transmissions.SOLUTION: For reporting the buffer status, the WTRU calculates a total amount of data available across all logical channels for which reporting is requested by a radio resource control (RRC) entity. The total amount of data includes an amount of data that is available for transmission and retransmission at a radio link control (RLC) entity and an amount of data that is available for transmission in medium access control for enhanced dedicated channel MAC-i/is segmentation entity when a MAC-i/is entity is configured. The WTRU sends scheduling information including a total E-DCH buffer status (TEBS) field that is set on the basis of the total amount of data.
