Abstract
Disclosed is a mechanism to help a user equipment device (UE) transmit multiple distinct bit streams concurrently to a base station with reduced risk of interference. The UE will orthogonally encode the multiple distinct bit streams using orthogonal binary codes to produce orthogonally encoded bit streams, and the UE will add the orthogonally coded bit streams together to produce a resulting bit stream and will transmit that resulting bit stream on an antenna path to the base station. Upon receipt of the transmitted bit stream, the base station could then apply the same orthogonal binary codes to the bit stream in order to extract the underlying multiple distinct bit streams.
