Background technology
Third generation partner plan (being called for short 3GPP) is a technology standardization tissue of implementing 3-G (Generation Three mobile communication system), and wherein the 3G (Third Generation) Moblie technical standard comprises Frequency Division Duplexing (FDD) (FDD) and time division duplex (TDD) pattern.3GPP is from setting up so far, respectively at having announced the Frequency Division Duplexing (FDD) (FDD) that mainly comprises 3.84Mcps and the 3-G (Generation Three mobile communication system) technical standard of time division duplex (HCR-TDD) in October, 1999, is called for short Release 99; Announce the 3-G (Generation Three mobile communication system) technical standard of the time division duplex (LCR-TDD) of the Frequency Division Duplexing (FDD) (FDD), time division duplex (HCR-TDD) and the 1.28Mcps that mainly comprise 3.84Mcps in 2000 again, be called for short Release4; And announced again that in calendar year 2001 the interpolation high-speed data packets inserts (HSDPA) in the 3-G (Generation Three mobile communication system) technical standard of the time division duplex (LCR-TDD) of Frequency Division Duplexing (FDD) (FDD), time division duplex (HCR-TDD) and the 1.28Mcps of 3.84Mcps, is called for short Release 5.At present, 3GPP is implementing the Frequency Division Duplexing (FDD) (FDD) of 3.84Mcps, the 3-G (Generation Three mobile communication system) up link technique for enhancing of the time division duplex (LCR-TDD) of time division duplex (HCR-TDD) and 1.28Mcps is given and being ground, and expection will be in formal research up link technique for enhancing standardization effort on the basis that above-mentioned up link technique for enhancing is given grinding in 2004, the technical scheme that is produced will be contained in the Frequency Division Duplexing (FDD) (FDD) of following 3.84Mcps, the 3-G (Generation Three mobile communication system) technical standard of the time division duplex (LCR-TDD) of time division duplex (HCR-TDD) and 1.28Mcps is called for short Release 6.
The no matter Frequency Division Duplexing (FDD) (FDD) of 3.84Mcps and the up enhancement techniques of time division duplex (HCR-TDD) in the 3-G (Generation Three mobile communication system), or the up link technique for enhancing of the time division duplex (LCR-TDD) of 1.28Mcps, its purpose all is by to the Frequency Division Duplexing (FDD) (FDD) by above-mentioned 3.84Mcps, the uplink transmission resource of the wireless network that 3-G (Generation Three mobile communication system) constituted of the time division duplex (LCR-TDD) of time division duplex (HCR-TDD) and 1.28Mcps, implement effectively management and planning, improve the coverage of the wireless area of the capacity of up link of said system and said system, so that be suitable for the stronger data service of transmitting burst; In addition, by improving the performance of uplink dedicated transmission channel, thereby improve the coverage rate and the throughput of sub-district, improve uplink speed, reduce uplink delay.
The discussion that 3GPP strengthens about up channel at first is Frequency Division Duplexing (FDD) (FDD) beginning from 3.84Mcps, and in June, 2003,20 meetings of RAN agree to begin one's study up channel of time division duplex (being called for short TDD) system strengthens.The main project of research comprises the scheduling of base station (Node B) control, the request retransmission of mixing (being called for short HARQ) etc., and wherein HARQ is that automatic re-transmission and chnnel coding with packet combines a kind of method of carrying out transfer of data.At fdd mode, up channel strengthens needs some new up signalings, and they are that scheduling is relevant, that HARQ is relevant or may need in the future.Although strengthen just to enter on about the up channel of TDD, similar with FDD, in order to support the scheduling and the HARQ of Node B control, new up signaling needs equally, and they are that scheduling is relevant, that HARQ is correlated with or may need future.
Dispatching method about base station (Node B) control, at fdd mode, 3GPP TR25.896V1.3.1 has comprised two kinds of main methods: a kind of is the rate scheduling method (also being two threshold scheme) of base station (Node B) control, and another kind is the speed and the time scheduling method of base station (Node B) control.For tdd mode, they also are possible scheduling schemes.
For the supporting rate dispatching method, two new message are introduced into: one is the speed application by name up signaling of (being called for short RR), is used for the speed threshold values of UE to Node B application lifting oneself; Another is that speed by name is replied the downlink signaling of (being called for short RG), is used for Node B and tells whether terminal (UE) allows the speed threshold values of its lifting oneself.The rate scheduling method of Node B control, its main thought is: each UE is in the initialization procedure of transmission channel, base station controller (RNC) is distributed to a transmission format composite set of UE (TFCS), and notify UE and control the base station (Node B) of described UE, RNC also provides two threshold values respectively simultaneously: one is the UE threshold value, and another is a Node B threshold value.This TFCS has comprised multiple transmission rate.In communication process, the transmission rate that UE is free to select to be no more than the UE threshold value is TFC, if UE need adopt the TFC bigger than UE threshold value, then UE improves described UE threshold value by the up signaling of RR to Node B request.Whether decision allows to improve the threshold value of described UE to Node B according to current factors such as interference, if allow, Node B tells UE by the RG downlink signaling.Attention UE threshold value in this process can not surpass Node B threshold value.
The time and the rate scheduling method of base station (Node B) control, its main thought is: information such as data buffering state that Node B sends according to UE and transmitted power surplus, accurate control UE delivery time, transmission data rate, and the control informations such as the time interval that send.Node B can know the maximum transmit power of described UE according to the power margin of UE.For supporting this scheme, required up signaling mainly comprises data buffering state (4 bit) and transmitted power surplus (4 bit).
At fdd mode, Fig. 1 has provided the up signaling of a kind of transmission: a kind of method of data buffering and transmitted power surplus, promptly use extra uplink physical channel, and be called the uplink scheduling control channel and send the required information of uplink scheduling.This scheme needs the outer up spread spectrum code word of occupying volume, and for the limited LCR-TDD system of up spread spectrum code word, this has not been a scheme.
HARQ is another subject matter of discussing during up channel strengthens.For supporting the quick HARQ of physical layer, required up signaling mainly comprises: new grouping indication (NDI, 1 bit), HARQ logical channel number (HARQ Process ID is called for short PID), rate-matched version indication (IRversion) etc.Wherein new grouping indication (NDI, 1 bit) is used for UE notice Node B, whether the grouping that is received is new grouping, whether Node B can will empty the buffering area (soft buffer) that is used for soft merging according to this new grouping indication decision, for example working as NDI is 1, what expression was transmitted is grouped into new grouping, after Node B receives this information, empties corresponding soft buffer.The transmission employing N of HARQ etc. stops mode, and being about to the HARQ channel distribution will be N logic channel, and the size of N is relevant with propagation delay time.UE notifies the Node B current transmission time interval logical channel number that (being called for short TTI) adopted by the HARQ logical channel number.In the HARQ agreement, for adaptive channel faster changes, the especially variation of the obtainable physics bit of each TTI, the 3GPP regulation and stipulation multiple parameters of rate matching, UE can select suitable parameters of rate matching according to actual conditions.Therefore UE need tell Node B the parameters of rate matching that it is adopted by IR version, and Node B separates rate-matched according to described parameter.
To sum up narrate, in up channel strengthens, required up signaling mainly comprises: the rate request RR relevant with scheduling, data buffering (4 bit) and transmitted power surplus (4 bit) and the new grouping indication (NDI relevant with HARQ, 1 information bit), HARQ logical channel number (Number:3 information bit of HARQ Process), rate-matched version indication (IRversion:3 information bit) etc.
At fdd mode,, following four kinds of possible schemes have been proposed mainly about the uplink signalings method:
1) adopt hole knockout in High-Speed Dedicated Physical Control Channel HS-DPCCH channel, some bits of promptly destroying on the HS-DPCCH transmit possible up signaling.
2) adopt hole knockout to transmit on special used for physical control channel DPCCH, some bits of promptly destroying on the DPCCH transmit up signaling.
3) up signaling is used as data, promptly introduces the special carrier signaling of new transmission channel, profit
With transformat combination indication (TFCI) this new transmission channel is transmitted on Dedicated Physical Control Channel DPDCH with other transmission channel is multiplexing.
4) redesign one newly and independently physical channel carry up signaling, promptly need to use an independent spread spectrum code word to transmit up signaling.
For LCR-TDD, the scheme of the up signaling that also not relevant at present transmission strengthens.So be necessary to design the uplink signalings method of the new LCR-TDD pattern that is applied to.
For fdd mode, it is possible that up enhancing channel (EUCH) and high-speed data shared channel (HS-DSCH) exist simultaneously; For tdd mode, this is similarly, also be that HSDPA and EUCH exist simultaneously also is possible.
In LCR-TDD, high-speed shared information channel (being called for short HS-SICH) is a uplink physical channel, ACK/NACK signaling that main carrying is relevant with HS-DSCH and channel quality indication (CQI) information (being called for short CQI), wherein CQI mainly comprises the modulation system indication (being called for short RMF) of 1 bit and transmission block size (the being called for short RTBS) information of 6 bits.
According to 3GPP TS25.221v5.5.0, Fig. 2 provides the coded system of HS-SICH among the LCR-TDD.201 steps of described figure, adopt (36,1) duplication code that the ACK/NACK of 1 bit is encoded, produce the ACK/NACK sequence behind the coding of 36 bits; In 202 steps of described figure, adopt (32,6) second order Reed-Muller sign indicating number that the RTBS of 6 bits is encoded and produce the information of 32 bits; In 203 steps of described figure, employing (16,1) duplication code is encoded to the RMF of 1 bit, produces the information of 16 bits; Totally 84 bits.
In document [Tdoc R1-02-1105, Simulations and Analysis of improvedHS-SICH Coding for 1.28 Mcps TDD (Samsung)], provide the performance curve of above-mentioned coded system correspondence, as shown in Figure 3.In Fig. 3, represent RTBS with TBSS.Typical B LER performance requirement for RTBS, RMF, ACK/NACK is respectively: for RTBS and MF, the performance requirement of BLER is 10
-2, be 10 for the performance requirement of ACK/NACK BLER
-4Not alignment of three's power requirement as seen from the figure, RTBS and RMF have the coding gain of overprotection in other words.The ascending power that this will cause wasting when sending each HS-SICH can bring the unnecessary uplink transmission to disturb thus.So should redesign the coding method of HS-SICH.The present invention proposes to use hole knockout, and the coded-bit of destroying overprotection transmits the method for the required up signaling of up enhancing.
At fdd mode,, following four kinds of possible schemes have been proposed mainly about the uplink signalings method:
1) adopt hole knockout in the HS-DPCCH channel, some bits of promptly destroying on the HS-DPCCH transmit up signaling.This mode is impossible for the LCR-TDD pattern, because there is not the HS-DPCCH channel of similar fdd mode in LCR-TDD;
2) adopt hole knockout in the DPCCH channel, some bits of promptly destroying on the DPCCH transmit up signaling.This mode also is impossible for the LCR-TDD pattern, because equally also there is not the DPCCH channel of similar fdd mode in LCR-TDD;
3) up signaling is used as data, promptly introduces the special carrier signaling of new transmission channel, utilize some transmission compound mode (TFCI) on DPDCH, to transmit with the data that send are multiplexing.This mode is possible for LCR-TDD.But its defective is a signaling only could be obtained behind demultiplexing, and the propagation delay time of promptly this mode signaling is bigger;
4) adopt one new, independently physical channel carries up signaling, promptly needs to use an independent spread spectrum code word to transmit up signaling; This mode also is possible for LCR-TDD, but up code word is limited in LCR-TDD, and this mode can increase up interference (PAR), increases the transmitted power surplus and the implementation complexity of terminal (UE).
Summary of the invention
The objective of the invention is provides a kind of uplink signalings method that up channel strengthens that is used for for the LCR-TDD system.
