Abstract
A radio telecommunication apparatus is used in a radio telecommunication system wherein one or more base stations broadcast radio signals over a plurality of radio channels. The apparatus selects at least a radio channel out of the plurality of radio channels and detects the availability of the selected radio channel. In response to the unavailability of the selected radio channel, the apparatus is intermittently powered so as to detect the availability of the selected radio channel while conserving battery power consumption. Even if the availability of the selected radio channel is detected, only reception and transmission sections are intermittently powered so that the presence of information signals to be transmitted is detected.
