<p>Introduction of discontinuous transmission in CDMA communications techniques is achieved by selectively using additional spreading codes for spreading a frame of data. By dividing a frame into two or more portions and spreading each portion with a different spreading code, the frame can be transmitted in a compressed mode wherein the information is transmitted during a portion of the frame period, leaving an idle part of the frame in which to perform other functions, such as evaluation of other frequencies for use in handover between frequencies.</p> |
