Abstract: A communication system (100) provides selecting a first modulation-coding scheme (111) based on a quality indicator of a communication between a source user and a first destination user, determining a first possible number of data bits (201) that can be modulated and encoded according to selected modulation-coding scheme (111) and spread according to one spreading code of a plurality of spreading codes (108-1 through 108-k) which results in fitting in a predetermined time frame, determining a first number of data bits (102) to be transmitted from the source user to the first destination user, determining a first load level based on comparing first number of data bits (102) and first possible number of data bits (201), and, if the first load level is unequal to a whole number, rounding to a next first whole number, selecting a first number of plurality of spreading codes (108-1 through 108-k) based on the first whole number of load level for spread coding of first number of data bits (102) after being modulated and coded according to selected modulation-coding scheme (111).
