Abstract:
A method for operating a wireless terminal in a wireless communication system that operates with frames time divided into slots each having a Header portion followed by a Data portion, wherein the system is arranged to transmit a downlink slot so that the Header portion is transmitted at a higher power level than the Data portion when the Data portion does not contain valid data so as to reduce system interference, comprising steps of:receiving the Header portion and only a part of the Data portion of a slot and detecting whether the Header portion was transmitted at a higher power level than the Data portion is being transmitted; and if it is detected that the Header portion was transmitted at a higher power level than the Data portion is being transmitted, terminating the reception of a remaining part of the slot and placing at least a portion of the wireless terminal in a reduced power consumption state; else if it is detected that the Header portion was transmitted at the same power level as the Data portion is being transmitted, continuing to receive the remaining part of the slot.
