Patent ID: 8830927

Claim:
A method comprising: selecting an uplink transmission scheme for a user terminal of a cellular telecommunication system; determining physical uplink shared traffic channel resources of the user terminal; allocating control message fields to resources of the physical uplink shared traffic channel according to the selected uplink transmission scheme so as to optimize transmission performance of control messages in the selected uplink transmission scheme; and determining a number of control symbols to be allocated to a given control message field in the resources of the physical uplink shared traffic channel on the basis of the number of bits to be transmitted in the control message field, the total number of bits to be transmitted in the resources of the physical uplink shared traffic channel, the number of subcarriers in a symbol block, the number of symbol blocks per sub-frame, and a quality offset defining an offset between desired reception qualities of traffic data and control data transferred in the control message field; coding the control symbols with a channel code selected on the basis of the determined number of control symbols; and mapping the coded control symbols of the control message fields to the frequency resource elements of the symbol blocks according to the selected uplink transmission scheme.
