METHOD FOR GENERATING CODE MASK USED FOR CODING TRANSMISSION THROUGH TRAFFIC CHANNELS, ESPECIALLY CONCERNED WITH PROVIDING PECULIARITY AT WANTED LEVEL TO DIFFERENTIATE BETWEEN MOBILE STATION TRAFFIC CHANNEL COMMUNICATIONS

摘要

PURPOSE: A method for generating code mask used for coding transmission through traffic channels, especially concerned with providing peculiarity at wanted level to differentiate between mobile station traffic channel communications is provided to reduce overhead and complexity of base stations and mobile stations. CONSTITUTION: A plurality of base station differentiators are generated and a code mask is generated for coding transmission through traffic channels based on the plurality of base station differentiators. The plurality of base station differentiators are used to differentiate a space between the different base station transmission. A plurality of traffic differentiators are used to differentiate a space between the different traffic channels.
