Patent ID: 7593694

Claim:
A method for data transmission between a base station and a terminal in a communication system, comprising; transmitting data divided into time segments from the base station to the terminal over a data channel shared by a plurality of terminals; and notifying the terminal from the base station via one of at least two control channels, the base station notifying the terminal through control information comprising a series of pieces of control information, the control information also being divided into time segments, the base station notifying the terminal as to when data will be sent on the data channel to the terminal, the method further comprising: monitoring the at least two control channels at the terminal; receiving the control information at the terminal on a first control channel of the at least two control channels in a first time segment; and generating an individual decision parameter for each of the pieces of control information on the basis of the content of the respective piece of control information; wherein the control information transmitted over the first control channel has a first piece and a second piece of control information, the first piece of control information being transmitted two time segments before any data transmission on the data channel, and the second piece of control information being transmitted in at least one time segment subsequent to the first time segment; a first individual decision parameter is generated for the first piece of control information and a second individual decision parameter is generated for the second piece of control information; if the first individual decision parameter is negative, the data is not processed further and in the time segment directly following the first time segment all control channels are monitored; and if the first individual decision parameter is positive and the second individual decision parameter is negative, the data is not processed further and in a time segment directly following the time segment of the second individual decision parameter, only the first control channel is monitored.
