Abstract
The present invention provides a method and an apparatus for wireless communication between a base station and at least two mobile stations in a cellular system. The method comprises sending on a forward link at least one of a first and a second command to the at least two mobile stations that the base station is serving on a reverse link. The method further comprises controlling a transmission in at least one of a first and a second transmission mode of at least one mobile station among the at least two mobile stations on the reverse link based on the at least one of the first and second commands. Each of at least two mobile stations may determine a change of transmission mode between an orthogonal or a non-orthogonal transmission mode on a reverse link based on a message on a forward link. A scheduler at a serving base station may match scheduling or transmission resources to the transmissions on the reverse link. The mobile stations being served may use orthogonal and non-orthogonal transmission modes for the transmissions in a non-overlapping fashion in any combination of time, frequency and spatial domains. By selectively assigning a set of mobile stations to the orthogonal or…
