A communication method used in a mobile station apparatus which performs communication using a TDMA frame formed by eight slots, a start of a TDMA frame on an uplink being delayed by three slots or three slots minus a fraction of a slot from a start of a TDMA frame on a downlink, the method comprising:

  • receiving using a reception slot of the TDMA frame on the downlink after getting ready to receive;

    transmitting using a transmission slot of the TDMA frame on the uplink after getting ready to transmit; and

    performing adjacent cell signal level measurement before either getting ready to receive or getting ready to transmit,wherein (I) when a number of transmission slots used in one TDMA frame on the uplink is below a predetermined number, then, after transmitting using a transmission slot of the TDMA frame on the uplink, a time allocation of two consecutive slots shall apply for performing adjacent cell signal level measurement and getting ready to receive and (ii) when the number of transmission slots used in one TDMA frame on the uplink is the predetermined number, then, after receiving using a reception slot of the TDMA frame on the downlink, a time allocation of two consecutive slots shall apply for performing adjacent cell signal level measurement and getting ready to transmit.
