Abstract

The present invention provides a method for supporting downlink JD (joint detection) in a TDD-CDMA (time division duplex-code division multiple access) communication network system, comprising steps of: judging whether the CAI (code allocation information) in a downlink timeslot will change in the next TTI (transmission time interval); if the CAI will change, inserting the changed CAI as a specific control information into a specified field in the traffic burst in the downlink timeslot corresponding to current TTI; sending the traffic burst containing the specific control information to each UE (user equipment) in the downlink timeslot via a downlink channel.
