Communication terminal apparatus for sending shared channel information based on the assignment status

摘要

A deciding unit (301) decides whether or not a DSCH has been assigned to the local terminal, and outputs a decision result indicative signal to a transmission control unit (102). The transmission control unit (102) appropriate changes the transmission frequency of a signal including shared channel information in accordance with the decision result by the deciding unit (301). That is, the transmission control unit (102) outputs the signal including the shared channel information to a modulator unit (103) at a high frequency when a DSCH has been assigned to the local terminal; and the transmission control unit (102) outputs the signal including the shared channel information to the modulator unit (103) at a low frequency when no DSCH has been assigned to the local terminal.
