Description

The method and apparatus that transmits and receive data highly reliably in the mobile communication system

Technical field

A kind of mobile communication system of supporting Packet data service of relate generally to of the present invention.Specifically, the present invention relates to a kind of method and apparatus that is used to send the needed control information of h-arq (HARQ).

Background technology

Universal mobile telecommunications service (UMTS) is to use the 3-G (Generation Three mobile communication system) based on the Wideband Code Division Multiple Access (WCDMA) (WCDMA) of European global mobile communication (GSM) system and general packet radio service (GPRS), it provides with 2Mbps or the higher smooth traffic that sends packet-based text, digitized voice, video and multi-medium data to mobile subscriber or computer user, no matter and their positions in the world how.

Specifically, the UMTS system uses the transfer channel that is called as Enhanced Uplink Dedicated Channel (E-DCH or EUDCH), so that further improve the packet transmitting performance of (commutative with the base station) uplink communication from subscriber equipment (UE) to Node B.In order to obtain more stable high speed data transfer, adaptive modulation and coding (AMC), HARQ, shorter Transmission Time Interval (TTI) and the scheduling of Control Node B have been introduced in transmission for E-DCH.

AMC is the technology that is used for according to the channel status between Node B and UE determining adaptively modulation and encoding scheme (MCS).Can define many MCS layers according to available modulation scheme and encoding scheme.The adaptively selected service efficiency that improves resource according to the MCS layer of channel status.

HARQ is used for packet retransmission with the packet retransmission scheme of correction in the mistake of the grouping of initialization.Shorter TTI is such technology, is used for reducing the throughput of retransmitting time delay and therefore improving system by making can use than the 10 milliseconds the shortest shorter TTI of TTI that is provided by 3GPP Rel5.Current, consider 2 milliseconds of length as so shorter TTI.

The scheduling of Control Node B is such scheme, wherein, Node B determines whether to allow the E-DCH transmission of UE, if and allow, then definite maximum data rate that is allowed, and to the determined data rate information of UE transmission as scheduling grant, and UE determines available E-DCH data transfer rate according to described scheduling grant.

By for example carrying out the scheduling of Control Node B, so that be no more than the performance of target RoT with the raising total system in the noise rising or heat rising (RoT) measurement of Node B to long-range UE distribution low data rate with to UE distribution High Data Rate nearby.RoT represents that it is defined as by the uplink radio resources of Node B use:

RoT＝I _o/N _o.....(1)

Wherein, I _oThe total amount of the uplink signal that be illustrated in power spectral density on total frequency acceptance band, promptly receives in Node B, No represents the thermal noise power spectral density of Node B.Therefore, the maximum RoT that is allowed is the total uplink radio resources that can be used for Node B.

Described total RoT be expressed as interference, divert voice traffic and the E-DCH traffic between the sub-district and.Use the scheduling of Control Node B, prevent to send grouping simultaneously from a plurality of UE, total RoT is remained on target RoT or lower, therefore guaranteed receptivity with High Data Rate.

Fig. 1 shows the figure that is used for the type signal stream that data send and receive on E-DCH.Under situation shown in Figure 1, UE sends uplink data on E-DCH, and Node B is carried out the scheduling of Control Node B for described UE.

Referring to Fig. 1, set up E-DCH in step 102 Node B and UE.The message that step 102 relates on dedicated transport channel transmits.104UE sends schedule information to Node B in step.Described schedule information can comprise: uplink channel state information, and it comprises transmitted power and the power headroom of UE; And the quantity that will send to the buffered data of Node B.In step 106, the Node B monitoring sends with the uplink data of dispatching each UE from the schedule information of a plurality of UE.When Node B determined that approval sends from the uplink packet of described UE, it sent to UE and comprises the scheduling grant of dispatching assignment information at step S108.Scheduling grant indication with the maximum data rate that is allowed or the maximum data rate that is allowed and the transmission that allowed regularly upwards/keep/downwards.In step 110, UE determines the TF (E-TF) of E-DCH according to described scheduling grant.UE sends E-TF information in step 112 to Node B then, and also sends system for uplink packet data in step 114 on E-DCH.Determine whether that in step 116 Node B E-TF information and system for uplink packet data have mistake.In step 118, in any one of TF information and system for uplink packet data, exist under the situation of mistake, Node B is being confirmed/is denying to deny (NACK) signal to the UE transmission on (ACK/NACK) channel, and under the situation about all being free from mistakes in both, Node B is being confirmed/is denying to send affirmation (ACK) signal to UE on the channel.Under latter event, finish grouped data and send, and UE sends new grouped data to Node B on E-DCH.On the other hand, in the previous case, UE retransmits same grouped data to Node B on E-DCH.

In order to carry out efficient scheduling under above-mentioned situation, Node B is from the schedule information of UE reception about buffer occupancy and power rating.According to described schedule information, Node B is distributed low data rate to long-range UE, the UE in bad channel state and the UE with data of low class of service, and distributes High Data Rate to nearby UE, the UE in good channel conditions and the UE with data of high class of service.In this case, need a kind of technology of exploitation, be used for sending and the receiving scheduling permission, it can be absolute permission (AG) or relative grant (RG), absolute permission (AG) is used to indicate the absolute value of the maximum data rate that is allowed of UE, relative grant (RG) be used to indicate in the past a maximum data rate that is allowed upwards/keep/downwards.

Embodiment

The item of definition is provided to help comprehensively understand embodiments of the invention in this manual such as detailed structure and element.Therefore, person of skill in the art will appreciate that and under situation about not departing from the scope of the present invention with spirit, to carry out various changes and the modification of embodiment described herein.And, for clarity and conciseness, omit explanation for known function and structure.

Explanation some exemplary embodiment of the present invention in the environment of the E-DCH of UMTS below.The physical channel that is called as E-DCH absolute grant channel (E-AGCH) carries AG from Node B to UE.The node B scheduling device according to the schedule information that receives from UE and Node B can with uplink radio resources determine described AG.

Described AG can comprise: be used to indicate the data maximum data rate that is allowed of maximum quantity of the uplink radio resources that can be used for UE or the power bias that is equal to the described maximum data rate that allows; AG validity duration indicating device is used to indicate AG how long effective; And AG validity processing indicating device, be used to indicate whether that AG handles for a specific HARQ or the HARQ processing of an integral body is effective.The maximum power ratio of the Dedicated Physical Data Channel that power bias is defined as strengthening (E-DPDCH), on the Dedicated Physical Data Channel of described enhancing, E-DCH is controlled with reference to physical channel to its power by map, i.e. Dedicated Physical Control Channel (DPCCH).The AG validity duration indicating device of the maximum data rate that is allowed of 4-8 bit or power bias, 1 bit and the AG validity of 1 bit are handled indicating device and are considered.E-AGCH also requires being used on common signal channel to discern the UE-ID and the Cyclic Redundancy Check sign indicating number that is used for detecting from AG mistake of UE.Each has 16 bits described UE-ID and CRC, and on a bit basis by mould-2 computing.They are included in the control information that provides on the E-AGCH with AG with the form of 16 bit CRC of use UE-ID shielding.

Therefore, the control information of E-AGCH can be 21-26 bit altogether on length.This control information, particularly AG are intended to be used for the valid wireless electric resources and distribute, and therefore require high reliability in transmission.Usually, communication system uses chnnel coding to be used for high reliability data transmission/reception.Described chnnel coding makes that receiver can be by proofreading and correct transmission error to the information of transmission data additional redundancy.

The convolutional code with constraint length 9 and 1/3 encoding rate that defines in the 3GPP standard can be taken as and be used for the channel coding technology that high reliability E-AGCH sends and receives.The 21-26 bit control information that will provide on E-AGCH is by attached 8 tail bits, then the convolutional encoding by 1/3 speed be encoded as the 87-102 coded-bit ((21+8) * 3=87, (26+8) * 3=102).

Fig. 2 A shows the convolution coder 200 with constraint length 9 and 1/3 encoding rate that defines in the 3GPP standard.

Referring to Fig. 2 A, convolution coder 200 comprises 8 serial shift registers 202,204,206,208,210,212,214 and 216 and a plurality of

adder

202b, 202c, 204a, 204c, 206a, 206b, 208b, 210a, 210c, 212a, 214a, 214b, 216a, 216b and 216c, is used to receive input information bits or the output bit of shift register 202-216.The input information that comprises 8 tail bits since first bit in regular turn by shift register 202-216, and with output0, output1, output2, output0, output1, output2 ... order produce the bit of coding.

The control information of chnnel coding is provided in 2 milliseconds of TTI of E-AGCH.If 256 spreading factor (SF) and quadriphase PSK (QPSK) are applied to E-AGCH, then can in described 2 milliseconds of TTI, send 60 bits altogether.Therefore, from the coding control information of E-AGCH delete cut (puncture) 27 bits (=87-60) to 42 bits (=102-60).Can use rate-matched to be used to delete cuts.Described rate-matched is deleted by the precalculated position in the bit stream of the chnnel coding of a piece and is cut or repetition bits and with the quantity Matching of the bit of the chnnel coding quantity to the sent bit on physical channel.Generally, delete bit position that cut or repetition in the rate-matched moderate distance.

But the rate-matched of undersized control information---such as 20 bits that provide on E-AGCH---makes and is difficult to realize best BLER (block error rate) (BLER).If the such piece of bit with lesser amt is by convolutional encoding and rate-matched, the then described low bit error rate (BER) (BER) of beginning and end experience has high BER in the middle of it simultaneously.Therefore, described BLER is enhanced, and the reliability of E-AGCH reduces.The existence of at least one incorrect bit causes a BLER in a piece.Have high BER if but the specific part of a piece has low BER remainder, then from the angle of BLER, this will cause degradation rather than performance improvement.

Can be by reducing the transmission and the reception of the high reliability (being that mistake is few) that its BLER realizes the E-AGCH control information.And traditional rate-matched causes the big BER skew in each bit position of piece.

In this case, exemplary embodiment of the present invention is intended to provide rate-matched, the control information that this has minimized BLER and has made it possible to send tile size.For this reason, proposed a plurality of rate matching pattern, they minimize the change of BER in each bit position of a piece of control information after the convolution chnnel coding, have therefore reduced the BLER of the E-AGCH that the control information of the small size of about 20 bits is provided.

Can realize a plurality of rate matching pattern in certain exemplary embodiments of the present invention, the BLER performance of the control information that provides on E-AGCH can be provided for they.First to the 6th exemplary embodiment belongs to the correspondence transmission of a plurality of rate matching pattern and 7 bit A G, 8 bit A G, 9 bit A G, 10 bit A G and 5 bit A G and the example that receives respectively.

Exemplary embodiment 1

The rate matching pattern that is used for 6 bit A G is provided as the example of realization of the present invention.For example, described AG comprises: be used to represent UE can with uplink radio resources maximum quantity 4 bits the maximum data rate that allows or be equal to the 4 bit powers biasing of the described maximum data rate that allows; The AG validity duration indicating device of 1 bit is used to indicate AG how long effective; And the AG validity of 1 bit is handled indicating device, is used to indicate whether that AG handles for a specific HARQ or the HARQ processing of an integral body is effective.Perhaps, described AG comprise 5 bits the AG validity duration indicating device of the maximum data rate that allows or power bias and 1 bit.

In the 3rd example, described AG comprise 5 bits the AG validity of the maximum data rate that allows or power bias and 1 bit handle indicating device.Perhaps, AG be configured to comprise 6 bits altogether the maximum data rate that allows or power bias, AG validity duration indicating device, AG validity handle indicating device and other E-AGCH control bits.

Except AG, E-AGCH also carries the CRC that is used to discern the UE-ID of UE and is used for detecting from AG mistake.Each has 16 bits described UE-ID and CRC, and based on a bit and by Modulo-two operation.Therefore, they are sent out with the form of using UE-ID to shield 16 bit CRC.The CRC of this 16 bit is called as the specific CRC of UE-ID.Described UE can determine whether that the AG that is received is intended to described UE by the specific CRC of UE-ID.8 end bit are added to the control information of 22 bits, and make the AG of 6 bits be connected to the specific CRC of UE-ID of described 16 bits, and with constraint length 9 with 1/3 encoding rate convolutional encoding.As a result, generation is as the piece of a chnnel coding of the coded bit stream of 90 bits.Delete from the piece of the chnnel coding of described 90 bits and to cut 30 bits, produce the rate matching block of 60 bits among 2 milliseconds of E-AGCH TTI that use 256 SF and QPSK, to send.Come the rate matching pattern of the position of the bit that analog representation deleted section with the change of the BER of each bit position of being reduced in rate matching block and the mode of therefore improving the BLER performance.Can obtain following rate matching pattern.

The element representation of each rate matching pattern will be deleted the position of the bit that cuts in the bit #1-#90 of chnnel coding.Under the situation of given 10 milliseconds of E-AGCH TTI, described 2 milliseconds of E-AGCH TTI take place five times.

Fig. 3 according to one exemplary embodiment of the present invention, be used to send the block diagram of the Node B transmitter of E-AGCH.

Referring to Fig. 3, under the situation of input 6 bit A G 302, the specific CRC adder 304 of UE-ID produces the CRC of 16 bits from described AG, by being carried out Modulo-two operation with the 16 bit UE-ID that are used to discern UE, the CRC of described 16 bits produces the specific CRC of UE-ID to receive AG, then with specific CRC of UE-ID and AG combination, the control information that produces 22 bits thus.Control information to described 22 bits adds 8 tail bits with channel encoder 308---use have the convolution code of constraint length 9 and encoding rate 1/3---, and is the encoding block of 90 bits with described 30 bit information convolutional encodings.Rate matchers 310 is deleted the encoding block that cuts described 90 bits with predetermined rate matching pattern.Physical channel mapper 312 with the piece map of rate-matched to a physical channel frame that is configured to be suitable for 2 milliseconds of E-AGCHTTI.Therefore, on E-AGCH 314, send described control information.Simultaneously, control information transmit control device 316 is controlled the transmission of the control information of E-DCH by the specific CRC adder 304 of UE-ID, channel encoder 308, rate matchers 310 and physical channel mapper 312.In a kind of example implementation mode, the encoding rate of control information transmit control device 316 management channel encoders 308 and the rate matching pattern of rate matchers 310.Control information transmit control device 316 at least one above-mentioned rate matching pattern of storage, and to one of described rate matching pattern of rate matchers 310 application.Default employed rate matching pattern between transmitter and receiver.Control information transmit control device 316 can be merged in grouped data and receive the controller (not shown), is used to be controlled at the reception that E-DCH goes up grouped data.

Fig. 4 according to one exemplary embodiment of the present invention, be used to receive the block diagram of the UE receiver of E-AGCH.

Referring to Fig. 4, UE is received signal on E-AGCH 402.Physical channel removes the piece of mapper 404 from 2 milliseconds of TTI extraction rate couplings the signal that is received.Speed goes adaptation 406 to delete the bit that cuts by recover (promptly go to delete and cut) according to the rate matching pattern of using in the delete bit position filling 0 that cuts in the rate matchers 310 of Node B for rate matching block by rate matchers 310.If E-AGCH 402 uses the 10 milliseconds of TTI of 2 milliseconds of TTI with 5 repetitions, then physical channel goes mapper 404 and speed to go adaptation 406 to carry out described identical operations 5 times, and resultant coded sub-blocks is combined as an encoding block.

The encoding block that channel decoder 408 decodings go adaptation 406 to receive from speed.Described encoding block is divided into the AG of 6 bits and the specific CRC of UE-ID of 16 bits.The specific CRC extractor 410 of UE-ID carries out the CRC that Modulo-two operation extracts 16 bits by the described 16 bit UE-ID 412 with specific CRC of the UE-ID of described 16 bits and UE, and provides CRC and the described AG that is extracted to CRC verifier 414.The CRC of described 16 bits of CRC verifier 414 checks is to detect mistake from described AG.If CRC upchecks, then CRC verifier 414 is exported the AG 416 of zero defects.AG416 is used for determining the maximum data rate that is allowed of E-DCH data.If CRC checks failure, then abandon described AG.

Simultaneously, control information reception controller 418 goes mapper 404, speed to go adaptation 406, channel decoder 408, the specific CRC extractor 410 of UE-ID and CRC verifier 414 to control the reception of the control information of E-DCH by physical channel.In a kind of implementation of example, control information receives controller 418 management speed and removes the rate matching pattern of adaptation 406 and the encoding rate of channel decoder 408.Control information receives controller 418 at least one above-mentioned rate matching pattern of storage, and goes adaptation 406 to use one of described rate matching pattern to speed.Control information receives controller 418 and can be merged in the grouped data transmit control device (not shown), is used to be controlled at the transmission of the grouped data on the E-DCH.
