A method, device and system for transmitting control information of enhanced uplink dedicated channel

Abstract

The invention discloses a method for transmitting control information of enhanced uplink special channels, a device and a system. The method comprises the following steps that: modulation mode information is borne in an E-DPCCH data frame and sent; after a receiving party receives the data frame, the modulation mode information determines the modulation mode of the E-DPCCH; the modulation mode information is used to demodulate the data information borne by the E-DPCCH. The embodiment of the invention can also bear RSN information or E-DCH RV information used to indicate constellation version index information into the E-DPCCH data frame and send the E-DPCCH data frame; the receiving party uses the RSN information or the E-DCH RV information to determine the constellation version index information, and uses the constellation version index information to demodulate the data information borne by the E-DPDCH. The embodiment of the invention transfers the 160AM modulation mode information and the constellation version index information to the receiving party under the condition of not increasing the complexity of the hardware and not changing the definition of the prior RSN.

Description

technical field [0001] The present invention relates to the technical field of electronic communication, in particular to a method, device and system for transmitting enhanced uplink dedicated channel control information. Background technique [0002] With the rapid development of the third generation communication technology, many new technologies have emerged. Among them, HSDPA (High Speed ​​Downlink Packet Access) technology is a downlink wireless enhancement technology introduced in Release (version) 5 by 3GPP (Third Generation Partnership Project). HSDPA technology has key technologies such as link adaptive technology based on adaptive modulation and coding, HARQ (Hybrid Automatic Repeat Request) based on physical layer retransmission and soft combining, fast multi-user packet scheduling, and 2ms short frame. It has the advantages of high spectrum efficiency, high downlink transmission rate, and small transmission delay, so it can provide effective support for packet d...

Problems solved by technology

[0020] The technical solution for transmitting E-DCH control information in the prior art meets the needs of the existing E-DPDCH for data transmission. However, the E-DPDCH proposed for RAN1 (Radio Access Network) adopts 16QAM (Quadrature Amplitude Modulation) modulation method According to the technical solution, the existing E-DPCCH that carries the control information required for demodulation and reception of E-DPDCH does not support 16QAM, that is, the existing technical solution for transmitting E-DCH control information cannot transmit 16QAM modulation information, and at the same time cannot Transmission of constellation version index information under 16QAM modulation mode

[0021] Therefore, there is currently no E-DCH control information transmission technology that can transmit 16QAM modulation information and constellation version index information
