Description

The coding of HS-SCCH signaling and processing method in the TD-SCDMA system HSDPA

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 of 3G (Third Generation) Moblie gpp (3GPP) standard definition 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 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 1/2 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 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.

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 (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 the terminal with new control information through 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 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 (Transmission Time Interval), each HS-SCCH can only carry the relevant downlink signaling of HS-DSCH for a terminal.

Fig. 2 shows the coding/multiplexing flow process of HS-SCCH channel among the present TD-HSDPA.The signaling that HS-SCCH carries is: spreading code set information (8 bit) X _{Ccs, 1}, X _{Ccs, 2}, X _{Ccs, 3}, X _{Ccs, 4}, X _{Ccs, 5}, X _{Ccs, 6}, X _{Ccs, 7}, X _{Ccs, 8}Gap information (5 bit) X _{Ts, 1}, X _{Ts, 2}..., X _{Ts, 5}Modulation system information (1 bit) X _{Ms, 1}Transport block size information (6 bit) X _{Tbs, 1}, X _{Tbs, 2}..., X _{Tbs, 6}Hybrid automatic repeat request process information (3 bit) X _{Hap, 1}, X _{Hap, 2}, X _{Hap, 3}Redundancy version information (3 bit) X _{Rv, 1}, X _{Rv, 2}, X _{Rv, 3}New data indication (1 bit) X _{Nd, 1}HS-SCCH cyclic sequence number (3 bit) X _{Hcsn, 1}, X _{Hcsn, 2}, X _{Hscn, 3}Terminal iidentification number (16 bit) X _{Ue, 1}, X _{Ue, 2}... X _{Ue, 16}

The step of the coding of HS-SCCH channel/multiplexing is following:

Step S20: spreading code set, gap information, modulation system information, transport block size information, HARQ information, redundancy version information, new data indication and cyclic sequence number are carried out information multiplexing, obtain a ₁, a ₂..., a _A

Step S21: the CRC (CRC) together with terminal iidentification number adds obtains b ₁, b ₂..., b _B

Step S22: chnnel coding obtains c ₁, c ₂..., c _c

Step S23: rate-matched obtains f ₁, f ₂..., f _R

Step S24: interleaving treatment obtains v ₁, v ₂..., v _R

Step S25: physical channel segmentation obtains u _{P, 1}, u _{P, 2}..., u _{P, Up}

Step S26: physical channel mapping.

High-speed shared information channel (HS-SICH) is the used ascending control channel of TD-HSDPAs, also is a physical channel, and it is used to feed back relevant uplink information.Mainly comprise to base station (Node B) and transmit ACK/NACK signaling and the channel quality indicator (CQI) that is used to support HARQ.CQI comprises the modulation format RMF of suggestion and the defeated block size RTBS of suggestion.Node B can determine the transformat of transmission next time with reference to this CQI.

Fig. 3 shows the coding/multiplexing flow process of HS-SICH channel in the present TD-SCDMA system.The signaling that HS-SICH carries has: recommend modulation system (RMF) (1 bit) X _{Rmf, 1}Recommend transmission block size (RTBS) (6 bit) X _{Rtb, 1}, X _{Rtbs, 2}..., X _{Rtbs, 6}Mix automatic repeat requests confirmation ACK/NACK (1 bit) X _{An, 1}

The flow process of the coding of HS-SICH channel/multiplexing is following.

Step S30:, obtain Z to recommending modulation system and recommending the transmission block size to carry out the CQI coding ₁, Z ₂..., Z _NCQI

Step S31: can with step S30 synchronous operation, encode to mixing automatic repeat requests confirmation ACK/NACK, obtain C ₁, C ₂..., C ₃₆

Step S32: it is multiplexing to carry out HS-SICH, obtains d ₁, d ₂..., d _U

Step S33: carry out HS-SICH and interweave, obtain V ₁, V ₂..., V _U

Step S34: carry out the physical channel mapping.

In the instruction that existing HS-SCCH carries, modulation system information $x_{\mathrm{Ms},1}=\left\{\begin{array}{ccc}0& \mathrm{If}& \mathrm{<figure-callout\; id="1"\; label="QPSK"\; filenames="S200810032754XE00021.png,S200810032754XE00031.png"\; state="\{\{state\}\}">QPSK</figure-callout>}\\ 1& \mathrm{If}& 16\mathrm{QAM}\end{array}\right..$

Spreading code is continuous dispensing between initial code and stop code, and comprises initial code and stop code.Initial code K _StartBy bit X _{Ccs, 1}, X _{Ccs, 2}, X _{Ccs, 3}, X _{Ccs, 4}Signaling, stop code K _StopBy bit X _{Ccs, 5}, X _{Ccs, 6}, X _{Ccs, 7}, X _{Ccs, 8}Signaling.

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 (in HS_SCCH, with representing, to use x among the HS-SICH _{Rmf, 1}Expression), this bit can only be supported QPSK (QPSK) 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 let 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 on the basis of 16QAM, improve 50%.

In the signaling of on HS-SCCH, being carried, spreading code set information, gap information, modulation system information and transport block size information have certain contact between four in configuration.Transmission block that transport block size information disposed size 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, press data that the modulation system that disposed transmits how much; This size finally can be converted the data throughput of each second through 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 can 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, can data block transmitted greater than failing the size that block size information is disposed; Judge that then this moment, modulation system was QPSK, otherwise judge that modulation system is 64QAM.

Though it is compatible that said method can guarantee with existing system, 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.
