Abstract
The invention discloses a method for coding high speed shared control channel (HS-SCCH) signaling in high speed downlink packages access (HSDPA) of a time division-synchronous code division multiple access (TD-SCDMA) system. The method supports the 64QAM higher-order modulation mode in addition to the existing two modulation modes QPSK and 16QAM. The technical proposal is as follows: since the serial number of the initial code is less than or equal to the serial number of the stop code in the spread spectrum code set, the information redundancy of the spread spectrum code set is represented by 8 bits, and some combinations are not utilized. The method provides the support for the higher-order modulation modes such as 64QAM by means of the combination of the redundant information and the existing information bit-based modulation mode, and improves the transmission performance and the bandwidth efficiency of the system. The method is applied to the field of mobile communication.
Description
Technical field
The present invention relates to the coding and the processing method of a kind of HS-SCCH (down control channel that HSDPA is special-purpose) signaling; Relate in particular among a kind of HSDPA (high speed downlink packet access) in the TD-SCDMA system; To the coding method of spreading code set information in the HS-SCCH signaling and modulation system information and terminal processing method, to increase the more modulation system of high-order to this coding signaling.
Background technology
Along with the continuous development of the communication technology and the user raising day by day to quality of service requirement, the message transmission rate that reaches as high as 2Mbit/s of 3G (Third Generation) Moblie gpp (3GPP) standard definition before Release 4 versions can not satisfy the user gradually to the demand of high-speed data service.In the case, 3GPP has introduced high speed downlink packet access (HSDPA) technology in Release 5 standards.
HSDPA is a kind of enhanced scheme that 3GPP Release 5 proposes, and main purpose is the high speed support to Packet data service, and obtains lower time delay, higher throughput of system and stronger QoS and guarantee.From technical standpoint, HSDPA strengthens air interface through introducing high speed descending sharing channel (HS-DSCH), and in UTRAN, strengthens corresponding functional entity.From bottom, mainly be that introducing mixes automatic repeat requests (H-ARQ) and Adaptive Modulation and Coding (AMC) technology increases data throughout.
The HARQ system introduces a FEC subsystem in the ARQ system; The error pattern that is used for correcting frequent appearance is to reduce number of retransmissions; Promptly in the error correcting capability scope; Automatically correct a mistake, exceed the error correction scope and then require transmitting terminal to resend data, this has increased the reliability and the efficiency of transmission of system.That is to say that the channel condition that H-ARQ can adapt to moment automatically provides trickle data rate adjustment.The AMC technology makes system in the scope of restriction, can adjust modulation and coded system adaptively according to the change of channel quality.In an AMC system, those channel conditions that sit pretty are user (normally those users very near apart from the base station) preferably, can be endowed the modulation system of high-order and the coded system of two-forty (such as 16QAM and 1/2Turbo encoding rate); And the relatively poor user's (normally those are in the user of cell boarder) of those channel conditions that are in unfavorable position then is endowed the modulation system of low order and the coded system of low rate (such as QPSK and 1/3Turbo encoding rate).
Fig. 1 shows the physical layer procedure of existing HSDPA.See also Fig. 1, the physical layer procedure of HSDPA mainly may further comprise the steps.
Step S101: terminal (UE) detects one's own HS-SCCH message, receives this message and demodulation, and this message is indicated information such as resource allocation conditions and the modulation system of next HS-DSCH (high speed descending sharing channel) transmission.
Step S102: the terminal receives HS-DSCH according to information such as the resource allocation conditions of HS-SCCH indication and modulation systems.
Wherein the terminal need obtain the modulation system of next one's own HS-DSCH according to the indication of HS-SCCH.
Step S103: the terminal is measured HS-DSCH accordingly.
Step S104: according to the measurement result to HS-DSCH, suitable transmission block size and modulation system are selected in the terminal, and produce a channel quality indication (CQI), and wherein the channel quality indication comprises recommendation modulation system RMF and recommends transmission block size RTBS.
Step S105: the channel quality indication that the terminal produces reports to base station (Node B) at corresponding ascending control channel (HS-SICH).
Step S106: the base station sends to the terminal with new control information through HS-SCCH, returns step S101.
HS-SCCH is the special-purpose down control channel of TD-HSDPA, is a physical channel, and it is used to carry all relevant bottom control information.That is to say that the terminal receives the data of HS-DSCH channel and must under the cooperation of HS-SCCH control information, could accomplish.HS-SCCH is initiated the professional terminal of HSDPA by all and shares, but concerning single HS-DSCH Transmission Time Interval TTI, each HS-SCCH can only carry the relevant downlink signaling of HS-DSCH for a terminal.
