Abstract:
1. In a communication system having at least one Node B serving a plurality of user equipments (UEs), said Node B transmitting a number of scheduling assignments for data packet transmissions to a corresponding number of said UEs using multiple modulation and coding schemes during a transmission time interval, a method to determine the resources for signal transmission from at least one of said number of UEs to said Node B in response to said data packet transmissions during said transmission time interval, said method comprising the steps of: said Node B transmitting a field with a predetermined modulation and coding scheme; said field providing at least the size of said scheduling assignments in each of said multiple modulation and coding schemes; at least one of said UEs decoding said field and determining said size of scheduling assignments in each of said multiple modulation and coding schemes; said at least one of said UEs transmitting a signal to said Node B in response to at least one of said scheduling assignments during said transmission time interval; and said at least one of said UEs determining the resources for transmitting said signal to said Node B from determining said size of scheduling assignments in each of said multiple modulation and coding schemes.
