Abstract:
A method and apparatus for uplink transmission over a non-contentious shared feedback channel are disclosed, wherein the parameters of the uplink transmission are determined by the parameters of a downlink transmission. A new uplink channel, called a physical shared uplink feedback channel (PSUFCH) is used for uplink transmission such as feedback information in response to a downlink transmission on a fast shared data channel. The content of the feedback information may be general, e.g. an ACK/NACK or a channel quality indicator (CQI). The PSUFCH is transmitted using power ramping that terminates upon reception of a downlink ACK (DLACK) from a Node-B. No ambiguity resolution is required due to the non-contentious and deterministic mapping of the uplink channel resources.
