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.

1. A wireless transmit/receive unit (WTRU) comprising:
a receiver configured to receive information from a wireless radio network, wherein the information indicates allowed transport block sizes to use for enhanced uplink transmission; a controller configured to identify, for a transmission time interval (TTI), a hybrid automatic repeat request (H-ARQ) process to use for transmission of data over an enhanced uplink channel; wherein the identified H-ARQ process is a synchronous H-ARQ process; the controller configured to select data for transmission over the enhanced uplink channel; the controller configured to select a transport block size, wherein the transport block size is selected based on the received information that indicates allowed transport block sizes; a transmitter configured to transmit the selected data over the enhanced uplink channel using the identified H-ARQ process; and the transmitter configured to transmit an indication of the selected transport block size over an associated physical control channel.
