Claim 0:
1. A user equipment, comprising:
a transmitter, which in operation, transmits a signal to a base station over a channel, wherein the signal is transmitted based on an initial channel quality information indicating a first channel quality of the channel and obtained by the user equipment before transmitting the signal;
a receiver, which in operation, receives, after transmitting the 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 transmitting the signal; and
a processing circuitry, which in operation,
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.
