Abstract  Abstract

A method for transmitting and receiving signals in consideration of a time alignment timer (TAT) which a user equipment (UE) runs after receiving a time alignment command (TAC) from a base station (BS) S1301. The UE transmits HARQ feedback information S1305 to a BS for a downlink signal received from the BS S1303 only when the TAT of the UE is running S1304.

Since the UE is not always located at a fixed position the transmission timing of the UE changes so when a TAC is received from the BS the UE assumes that the TAC is valid only for a specific time i.e. the UE assumes that it is in time synchronisation with the BS only when the TAT is running.
