Method and apparatus for dynamically adjusting data transmission parameters and controlling H-ARQ processes

摘要

A method and wireless transmit/receive unit (WTRU) for uplink data transmission is disclosed. Information indicating an allowed limit for uplink data transmission over an enhanced uplink channel is received. A hybrid automatic repeat request (H-ARQ) process to use for transmission of data over the enhanced uplink channel is identified. Data is selected for transmission over the enhanced uplink channel. A data transmission parameter is selected based on the received information indicating the allowed limit for uplink data transmission. The selected data is transmitted over the enhanced uplink channel using the identified H-ARQ process. An indication of the selected data transmission parameter is transmitted over an associated physical control channel.
