Abstract:
1. A method for use in a wireless transmit/receive unit (WTRU) that includes a receiver and at least one processor, the method comprising: the receiver receiving a plurality of communication signals having differing spreading factors, each communication signal having an associated code and comprising symbols; the at least one processor generating a plurality of transmission response matrices; the at least one processor grouping the plurality of transmission response matrices according to spreading factors associated with each of the plurality of transmission response matrices; the at least one processor assembling a plurality of spreading factor group matrices; the at least one processor forming a base matrix based upon a spreading factor group matrix of the plurality of spreading factor group matrices having a lowest spreading factor; the at least one processor selecting an additional spreading factor group matrix of the plurality of spreading factor group matrices for consideration; the at least one processor deriving a column placement reference index for the base matrix; the at least one processor deriving a reference location for the base matrix; the at least one processor deriving a column set from the selected additional spreading factor group matrix; the at least one processor inserting the column set into the base matrix; and the at least one processor assembling a total transmission response matrix.
