Abstract
A method and apparatus is offered of multiplexing control information into a user signal stream in a cellular communication system using code division multiple access. The method includes the steps of determining a temporal measure (101) of control information to be substituted for a corresponding measure of user information, substituting (102) the control information into the signal stream while buffering a corresponding temporal measure of user information, and resuming transmission (103) of user information beginning with the buffered user information.
