Claim 8:
9. A base station, comprising:
a receiver, which in operation, receives at least a part of a signal from a user equipment over a channel, wherein the signal is transmitted based on an initial channel quality information obtained by the user equipment before transmitting the signal and indicating a first channel quality of the channel;
a processing circuitry, which in operation, determines during processing the received signal a transmission quality information that is not an acknowledgement (ACK) or a non-acknowledgement (NACK) and that indicates a second channel quality of the channel used for receiving the signal; and
a transmitter, which in operation, transmits the transmission quality information upon determining the transmission quality information, wherein the user equipment estimates a transmission quality based on the initial channel quality information and the transmission quality information, compares the transmission quality to a threshold and determines that the transmission of the signal over the channel was successful in response to the transmission quality exceeding the threshold.
