Description
Technical field
The present invention relates to a kind of HS-SCCH (High Speed Shared Control Channel, High-Speed Shared Control Channel) coding of signaling and processing method, relate in particular to a kind of in the TD-SCDMA system, to the coding method of the spreading code set information in the HS-SCCH signaling, gap information, transmission block size and modulation system information and terminal processing method 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 that 3G (Third Generation) Moblie partner plan (3GPP) standard defined before the Release4 version 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 by introducing high speed descending sharing channel (HS-DSCH), and strengthens corresponding functional entity in UTRAN.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, be used for correcting the error pattern of frequent appearance 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 1/2 Turbo 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 1/3 Turbo 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 the resource allocation conditions of next HS-DSCH (high speed descending sharing channel) transmission and modulation system.
Step S102: terminal receives HS-DSCH according to information such as the resource allocation conditions of HS-SCCH indication and modulation systems.
Step S103: terminal is measured accordingly to HS-DSCH.
Step S104: according to the measurement result to HS-DSCH, terminal is selected suitable transmission block size and modulation system, and produces 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 terminal produces reports to base station (NodeB) at corresponding HS-SICH (High SpeedShared Information Channel shares the information Control channel at a high speed).
Step S106: the base station sends to terminal with new control information by HS-SCCH, returns step S101.
HS-SCCH is the down control channel that TD-HSDPA uses, and is a physical channel, and it is used to carry all relevant bottom control information.That is to say that terminal receives the data of HS-DSCH channel and must just can finish under the cooperation of HS-SCCH control information.HS-SCCH is shared by all terminals of initiating the HSDPA business, but concerning single HS-DSCH Transmission Time Interval TTI (Transmission Time Interval), each HS-SCCH can only be a relevant downlink signaling of terminal carrying HS-DSCH.

Can see that from coding/multiplexing flow process of HS-SCCH and HS-SICH in the standard of present TD-HSDPA, the modulation system indication information has only 1 bit (with representing, to use x among the HS-SICH in HS SCCH
Rmf, 1Expression), this bit can only be supported QPSK (Quadrature Phase Shift Keying) and two kinds of modulation systems of 16QAM (16 rank quadrature amplitude modulation) of existing system, and modulation system that can't back-up system increased newly, for example high order modulation more such as 32QAM, 64QAM.So, disturb the indoor preferably and outdoor microcellulor scene of isolation at some, even if the demodulation symbol signal to noise ratio is very high, the system throughput figureofmerit also will be subject to the 16QAM modulation system, no longer promote.
The HSDPA system introduces more that the 64QAM modulation system of high-order is inevitable, because 64QAM will allow availability of frequency spectrum approximation theory Shannon limit on higher SNR interval, significantly improves the throughput index of system.Using the 64QAM high-order modulating will make ultimate throughput and frequency efficiency improve 50% on the basis of 16QAM.
In the signaling of being carried on HS-SCCH, spreading code set information, gap information, modulation system information and transport block size information have certain contact between four in configuration.The transmission block size that transport block size information disposed is meant within a TTI, on the Radio Resource of specified sign indicating number territory of spreading code set information and gap information and time domain, presses what of data that the modulation system that disposed transmits; This size finally can be converted the data throughput of each second by the size of TTI.In other words, the sign indicating number territory that spreading code set information and gap information are specified and the Radio Resource of time domain are wanted to guarantee under the modulation system that is disposed the message transmission of the enough transmission block sizes of these resources.
Just be based on above-mentioned relation, on the basis of existing signalling coding of compatibility and decoding process, a kind of method that transmits newly-increased modulation system configuration is suggested.Its concrete grammar is, if modulation system information X
Ms, 1=1, judge that then modulation system is 16QAM; If X
Ms, 1=0, judge that then modulation system is QPSK or 64QAM; Work as X
Ms, 1=0 o'clock, if the Radio Resource of sign indicating number territory and time domain that spreading code set information and gap information are specified, under the QPSK modulation system, the size that can data block transmitted be disposed greater than defeated block size information, judge that then this moment, modulation system was QPSK, otherwise judge that modulation system is 64QAM.
Though said method can guarantee and the existing system compatibility, has added so implicit restriction: when a certain size transmission block promptly can also can be transmitted by the 64QAM mode by QPSK, QPSK can only select in system, perhaps transferred to select 16QAM.This is a kind of relatively more implicit indicating mode, can be as reference.When combining with clear and definite indicating mode, can be indicating modulation mode more fast.
In sum, support the signaling control of newly-increased modulation system in order to make TD-HSDPA, need to the control information in the control channel with before improve on the basis of system compatible, the permission system can realize the more selection and the configuration of high-order modulating.
Summary of the invention
The objective of the invention is to address the above problem, the coding method of HS-SCCH signaling in a kind of TD-SCDMA system HSDPA is provided, on the basis of two kinds of modulation system QPSK of existing support and 16QAM, also support the high-order modulating of 32QAM and 64QAM.
Another object of the present invention is to provide in a kind of TD-SCDMA system HSDPA terminal to the processing method of HS-SCCH signaling, corresponding above-mentioned coded system has been improved the signaling process mode of terminal.
