['3. A base station apparatus comprising: a transmitter configured to transmit a first physical signal used to schedule a second physical signal, wherein a transmit beam corresponding to the second physical signal is provided based on a timing at which the second physical signal is generated, and correspondence of the second physical signal to the transmit beam corresponds to a QCL relationship between a first antenna port to which the second physical signal is mapped and an antenna port corresponding to the transmit beam.', '5. A communication method for a terminal apparatus, the communication method comprising the step of: receiving a first physical signal used to schedule a second physical signal, wherein a receive beam corresponding to the second physical signal is provided based on a timing at which the second physical signal is generated, and correspondence of the second physical signal to the receive beam corresponds to a QCL relationship between a first antenna port to which the second physical signal is mapped and an antenna port corresponding to the receive beam.']
