20090196263 | WIRELESS RECEIVER - In a method for full discontinuous (DTX) control in a receiver in a wireless communication system it is determined if full DTX is allowed in a current timeslot. If not, then a full DTX indicator is set for the previous frame to false and the method ends. If full DTX is allowed, then it is determined if a special burst has been detected. If so, then the full DTX indicator is set for the previous frame to true and the method ends. If a special burst has not been detected, then it is determined if a transport format combination indicator (TFCI) has been accepted. If the TFCI has been accepted, then the full DTX indicator is set for the previous frame to false and the method ends. If the TFCI has not been accepted, then the method ends without setting the full DTX indicator for the previous frame. | 08-06-2009 |
