Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] figure 2 It shows the flow of a preferred embodiment of the high-order modulation uplink signaling transmission method in the TD-SCDMA system HSDPA of the present invention. See figure 2 , the following is a detailed description of each step in the method.

[0046] Step S20: The terminal receives a downlink control channel (HS-SCCH) message indicating resource allocation for the next high-speed downlink shared channel (HS-DSCH) transmission.

[0047] In this step, the terminal receives the HS-SCCH message, performs dephysical processing on the HS-SCCH, and extracts HS-DSCH control information.

[0048] Step S21: the terminal performs corresponding channel measurement.

[0049] In this step, the terminal receives the HS-DSCH at the allocated time interval according to the HS-SCCH control information, performs corresponding channel measuremen...

Abstract

The invention discloses a transmitting method of an HSDPA high-order modulating upstream signal of a TD-SCDMA system, overcomes the problem that existing systems can not indicate a high-order modulating way, and adopts the technical proposal that the method comprises the following steps: 1. a terminal receives a message from a downstream control channel and indicates transmission resource distribution situations of next high-speed downstream sharing channel; 2. the terminal implements channel measurement; 3. the terminal selects proper transmission block size and high-order modulating way according to the resource distribution situations of the high-speed downstream sharing channel and the channel measuring result, and generates channel quality indication; 4. the channel quality indication and acknowledgment information of a hybrid automatic retransmission request are encoded and multiplexed by adopting multiple Hadamard sequences or orthogonal code sequences, and then reported to a base station through a corresponding upstream control channel; and 5. high layers of the base station select proper transmission block size and high-order modulating way according to the channel quality indication report of the terminal and send the proper transmission block size and high-order modulating way to the terminal through the downstream control channel. The transmitting method of the HSDPA high-order modulating upstream signal of the TD-SCDMA system is applied to the field of mobile communication.

Description

technical field [0001] The present invention relates to an uplink signaling transmission method in a 3G mobile communication system, and in particular to a high-order encoding using Hadar code in HSDPA (High Speed ​​Downlink Packet Access) of a TD-SCDMA system (Time Division Synchronous Code Division Multiple Access system) Modulated uplink signaling transmission method. Background technique [0002] With the increase of mobile multimedia services, the transmission rate of 2Mb / s of the third generation mobile communication system will not be able to meet the requirements, and it is inevitable to develop a mobile communication system with larger capacity and higher bit transmission rate. Therefore, WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access), CDMA2000 and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) are all undergoing technical enhancements to develop high...
