The invention discloses a method for transmitting the user type information of the same time slot in a time-division synchronous code-division multi-address system, which is applied in a TD-SCDMA system adopting MIMO technology for conveniently indicating the user types of the same time slot. In the method, a base station side transmits the user type information of the same time slot to a terminalside by a descending high-speed share control channel during multi-input multi-output single-current transmission, and the user type information of the same time slot is used for representing the types of other users in the same time slot to the terminal side. By carrying the user type information of the same time slot on an HS-SCCH channel, the invention realizes the flexible dispatching of different user types in the same time slot.
Description
technical field [0001] The invention relates to a time division synchronous code division multiple access (TD-SCDMA) system, in particular to a method for transmitting user type information of the same slot in the time division synchronous code division multiple access system. Background technique [0002] Multiple-Input Multiple-Output (MIMO) technology is characterized by the introduction of multiple antennas in both the wireless transmitter and receiver. Compared with the traditional single-input single-output (SISO) system, the MIMO system has greatly improved the system capacity through space diversity technology or space multiplexing technology. [0003] In the same time slot, multiple users can coexist. However, since the Mid-amble codes in non-MIMO mode and MIMO mode adopt different allocation methods, the receiving end cannot accurately obtain the information of the used spreading codewords only according to the received Mid-amble codes, so that the receiving end ...
