Abstract:
1. A compressed mode downlink propagation path quality information transmitting method for normally transmitting downlink propagation path quality information in a scheduled period selected from an assumed period group in which transmission of the downlink propagation path quality information is assumed, the method comprising: a receiving step of receiving a radio signal comprising a pilot channel signal and a downlink control channel signal; a downlink propagation path quality information generating step of generating downlink propagation path quality information for each measurement reference period based on the pilot channel signal; an extracting step of extracting a control parameter from the downlink control channel signal; a timing generating step of: calculating a downlink transmission gap interval and an uplink transmission gap interval based on the extracted control parameter; given assumed periods which come after the downlink transmission gap interval has ended and which do not overlap the uplink transmission gap interval, determining sequentially whether a condition that a measurement reference period associated with the assumed period does not overlap the downlink transmission gap interval, is satisfied; and, in a first assumed period to satisfy the condition after the downlink transmission gap interval has ended, generating a timing for transmitting downlink propagation path quality information generated based on the pilot channel signal received in a measurement reference period associated with the first assumed period, as extra downlink propagation path quality information; and a transmitting step of transmitting the extra downlink propagation path quality information at the timing generated in the timing generating step.
