Abstract
A method and system for transmitting data from a UE in an OFDM system such as LTE. Information symbols are spread using a spreading code assigned to the UE and orthogonal to spreading codes of other UEs. The assigned spreading code has a spreading factor which is variable and dynamically selected based on one or more system performance criteria. The spread information symbols are transmitted in one or more LTE resource blocks. Spreading may be performed in the time domain, over a plurality of LTE time slots and/or resource elements.
