Transmission technology described herein can be used in various communication systems, for example CDMA, TDMA, FDMA, OFDMA and SC-FDMA system etc.Term " system " and " network " usually use interchangeably.Cdma system can be realized for example radiotechnicss such as general land wireless access (UTRA), cdma2000.UTRA comprises wideband CDMA (W-CDMA) and low spreading rate (LCR).Cdma2000 is contained IS-2000, IS-95 and IS-856 standard.Tdma system can be realized for example radiotechnics of global system for mobile communications (GSM).The OFDMA system for example can realize evolution UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20,

Deng radiotechnics.These various radiotechnicss and standard are well known in the art.UTRA, E-UTRA and GSM are the parts of universal mobile communication network (UMTS).Long Term Evolution (LTE) is the UMTS that will issue, and it has utilized E-UTRA.UTRA, E-UTRA, GSM, UMTS and LTE describe in the document of " third generation partner program " tissue (3GPP) by name.Cdma2000 describes in the document of " third generation partner program 2 " tissue (3GPP2) by name.For clarity sake, below the technology of the ul transmissions among the LTE with regard to related fields is described, used the term of 3GPP in the following major part explanation.

LTE has utilized OFDM (OFDM) on down link, utilized single carrier frequency division multiplexing (SC-FDM) on up link.OFDM and SC-FDM are divided into the subcarrier of a plurality of (N) quadrature with system bandwidth, and it is also referred to as sound (tone), piece (bin) or the like.Each subcarrier can be modulated with data.Usually, modulation symbol adopts OFDM to send in frequency domain, adopts SC-FDM to send in time domain.For LTE, the interval between the adjacent sub-carrier can be fixed, and the sum of subcarrier (N) can depend on system bandwidth.In a design, for the system bandwidth of 5MHz, N=512, for the system bandwidth of 10MHz, N=1024 is for the system bandwidth of 20MHz, N=2048.Usually, N can be any integer value.

This system can support Frequency Division Duplexing (FDD) (FDD) pattern and/or time division duplex (TDD) pattern.In the FFD pattern, independent frequency channels can be used for down link and up link, and down link and ul transmissions can be divided on other frequency channels at them and sent concomitantly.In tdd mode, common frequency channels can be used for down link and up link, and down link can send in some time durations, and ul transmissions sends in can be during other times.

The LTE downlink transmission scheme is divided by radio frame (for example, 10ms radio frame).Each frame comprises the pattern that is made of frequency (for example, subcarrier) and time (for example, OFDM symbol).The 10ms radio frame is divided into a plurality of adjacent 0.5ms subframes (being also referred to as subframe or time slot and replacedly use hereinafter).Each subframe comprises a plurality of Resource Block, and wherein each Resource Block is made of one or more subcarriers and one or more OFDM symbol.One or more Resource Block can be used for the transmission of data, control information, pilot tone or above-mentioned every combination in any.

Adopt mixing to retransmit (HARQ) automatically and improved reliability of data transmission.For example, in most systems, HARQ can be used for physical down link sharing channel (PDSCH) or physical uplink link sharing channel (PUSCH), the two can abbreviate shared data channel (SDCH) as, wherein packet at ground floor (L1) based on the affirmation of using acknowledgement channel (ACKCH) to send/deny transmitting again from UE.For the HARQ on down link, Node B can send the transmission of packet, and can send one or more re-transmissions, is correctly deciphered by UE up to packet, has perhaps sent the re-transmission of maximum quantity, has perhaps run into other end conditions.

The HARQ process can be represented all transmission and the re-transmission (if any) of packet.But the HARQ process can be in the resource time spent, and can termination after first transmission or one or more later retransmission.The HARQ process can have the variable duration, and it depends on the decode results at the receiver place.The HARQ process can be used by the UE or a plurality of UE that move in system.Each HARQ process can send on a HARQ pilotaxitic texture.In one aspect, each HARQ process can send (for example, subframe, time slot, Resource Block etc.) on a HARQ pilotaxitic texture.

For example, when resource and data ready, Node B is given UE with data packet transmission.If packet is received by UE, if packet is successfully handled, then UE can acknowledge, if wrong then send and deny when perhaps packet being deciphered.In response, deny or receiver expiration before receiving any affirmation that then Node B can retransmit this identical packet if receive.

According to an aspect, Fig. 3 shows down link and the ul transmissions process 300 of HARQ process at SDCH on the down link and the affirmation channel on up link.At the radio frame 330 of LTE system, the affirmation that shows the HARQ process on the SDCH and be associated/deny process.For instance, can on the different subframes of 10ms radio frame 330, adopt 5 HARQ processes.Can arrange each HARQ process to transfer data to different UE or identical UE.This depends on the scheduler of system.The quantity of the HARQ process that can adopt during radio frame depends on the requirement of system.For instance, repeat the HARQ processes with two groups and (for example, HARQ0-HARQ4) show 5 HARQ processes.First group comprises virtual resource blocks 302-310, and second group comprises virtual resource blocks 312-320.Each Resource Block that is used for down link is made of tone and symbols.The position of the frequency of each Resource Block of two groups is identical.Resource Block can be the part for the whole or subframe of the subframe of SDCH appointment.For clarity sake, HARQ process as herein described will be at first group of virtual resource blocks 302-310.The bandwidth (for example, the quantity of subcarrier and OFDM symbol) of distributing to each virtual resource blocks can change based on system requirements.

For each the HARQ process 302-310 on the down link (for example, use SDCH), exist affirmation on the corresponding up link/deny transmitting 352-360 (for example, using acknowledgement channel).Each Resource Block that is used for up link is made of tone and symbols.The position of the frequency of each Resource Block is identical in two groups.Resource Block can be the part for the whole or subframe of the subframe of SDCH appointment.The bandwidth (for example, the quantity of subcarrier and OFDM symbol) of distributing to each virtual resource blocks can change based on system requirements.

In HARQ, (for example, HARQ0) each packet of Fa Songing exists the affirmation of using acknowledgement channel/deny transmitting, and for example confirms 0 for use the HARQ process on SDCH.Setting up the required information of acknowledgement channel can a priori use different channels to send.In one aspect, the respective frequencies position that can impliedly depend on the SDCH on down link at the frequency location of each virtual resource blocks that is used for acknowledgement channel on the up link.Therefore, in this example, the starting position of the interior frequency 362 of subframe in the subframe on the down link on the starting position of frequency 332 and the up link is identical.In addition, as shown in Figure 3, can impliedly depend on the corresponding time location of the SDCH on the down link at the time location of each virtual resource blocks that is used for acknowledgement channel on the up link.In one aspect, corresponding to the time started position of the affirmation channel of HARQ process certain skew is arranged, as shown in 364.

According to an aspect, Fig. 4 shows in the HARQ of the SDCH on down link process and the down link and the ul transmissions process 400 that are used to be transmitted in the HARQ scheme of the affirmation of the affirmation channel on the up link/deny.According to an aspect, this HARQ process is to use transmission mode 450 to come the HARQ process of acknowledge/deny.Confirm/deny that transmission mode 450 can select based on various factors, for example confirm/deny to require to carry out the number of times of repetition.In one aspect, confirm to exist between the transmission mode (for example, confirming/deny transfer resource) implicit mapping relations at the DL of correspondence data resource (for example, HARQ process resource) and UL.Pattern can be the one or more Resource Block by time, frequency and coding definition.In one aspect, confirm/deny that transmission mode can impliedly depend on the time and the frequency location of corresponding packet.In one aspect, confirm/deny that transmission mode can impliedly depend on the time and the frequency location (for example, control channel is as PDCCH (physical downlink control channel)) of corresponding data allocations bag.

At the radio frame 430 of LTE system, the affirmation that shows the HARQ process on the SDCH and be associated/deny process.For instance, can on the different subframes of 10ms radio frame 430, adopt 10 HARQ processes.Each HARQ process can be arranged to transfer of data to different UE or identical UE.This depends on the scheduler of system.The quantity of the HARQ process that can adopt in during radio frame depends on system requirements.For instance, repeat the HARQ processes with two groups and (for example, HARQ0-HARQ4) show 10 HARQ processes.First group comprises virtual resource blocks 402-410, and second group comprises virtual resource blocks 412-420.Each Resource Block that is used for down link is made of tone and symbols.The frequency location of each Resource Block in two groups is identical.Resource Block can be the part for the whole or subframe of the subframe of SDCH appointment.For clarity sake, HARQ process described herein will be at first group of virtual resource blocks 402-410.The bandwidth (for example, the quantity of subcarrier and OFDM symbol) of distributing to each virtual resource blocks can change based on system requirements.

For each the HARQ process 402-410 on the down link (for example, use SDCH), exist affirmation on the corresponding up link/deny transmitting 452-460 (for example, using acknowledgement channel).Each Resource Block that is used for up link is made of tone and symbols.The frequency location of each Resource Block of down link is identical.The Resource Block of down link can be the part for the whole or subframe of the subframe of SDCH appointment.The bandwidth (for example, the quantity of subcarrier and OFDM symbol) of distributing to each virtual resource blocks can change based on system requirements.

In one aspect, can repeat to confirm/deny at the packet that uses the HARQ process to send.For the time that reduces the affirmation of notifying each UE when to transmit repetition clearly and the expense of position, use a plurality of affirmations to identify to each transmission Resources allocation.In one aspect, the frequency that is used for acknowledgement channel is divided into a plurality of sets of tones 462,464 and 466.In one aspect, for radio frame, each Resource Block of acknowledgement channel is divided into a plurality of sub-pieces on frequency, and wherein each sub-piece can be got essentially identical sets of tones 462,464 and 466.For each affirmation/deny transmission, use sub-piece to carry this transmission.Depend on the desired affirmation of packet/deny the number of transmissions at the sub-piece number of confirming/deny to transmit appointment.In one aspect, the sub-piece that is used for acknowledge/deny is a quadrature on time and frequency.This frequency division of acknowledgement channel is available in the LTE system, but does not dispose in invention fashion.

The division of frequency can be depended on the desired maximum of the UE in system the number of transmissions again.For example, if require UE to come again acknowledge/deny that the virtual resource blocks of the affirmation channel of radio frame is divided into 3 parts on frequency so with repeat factor 3; Perhaps, if require UE to come again acknowledge/deny that the virtual resource blocks of the affirmation channel of radio frame is divided into 2 parts on frequency so with repeat factor 2.The division of acknowledgement channel frequency on up link can have difference according to different radio frames, and this division is applicable to all Resource Block in the radio frame.On the one hand, the maximum repeat factor of any UE or packet can be restricted to 3, thereby the frequency of distributing to acknowledgement channel will be divided into 3 parts.

In one aspect, the repeat factor of each HARQ process use can dynamically be revised or be set in advance.Repeat factor is based on the peak frequency of distributing to acknowledgement channel and correctly carry out acknowledge/deny needed minimum frequency and be restricted.In one aspect, repeat factor can be different for each frame.Repeat factor can be asked by UE, perhaps distributes to UE based on the situation that records.Repeat factor can preestablish at specific Node B and at certain duration.Repeat factor can calculate based on available bandwidth.The affirmation that repeat factor can not receive based on node/deny that number calculates.Node B can be adjusted the repeat factor of HARQ process, and it depends on Node B because do not receive any affirmation and the number of times that retransmits from UE.In addition, repeat factor can a priori use more high-rise signaling to provide.Repeat factor can divide timing to provide in acknowledgement channel.In one aspect, Node B is analyzed the affirmation number that receives continuously, affirmation number that abandons (because first affirmation is correctly received) and the affirmation number that does not receive.Use this data, Node B can be adjusted the repeat factor of UE.

Return with reference to figure 4, according to an aspect, be based upon 3 maximum repeat factor, modes of uplink transmission 450 is described as exemplary patterns in this article.In this example, the data of HARQ process 0 are transferred to UE, and the repetition that repeat factor is 3 affirmation/deny is carried out in its requirement; The data of HARQ process 1 are transferred to UE, and the repetition that repeat factor is 1 affirmation/deny is carried out in its requirement; The data of HARQ process 2 are transferred to UE, and the repetition that repeat factor is 1 affirmation/deny is carried out in its requirement; The data of process 3 are transferred to UE, and the repetition that repeat factor is 2 affirmation/deny is carried out in its requirement; The data of HARQ process 4 are transferred to UE, and the repetition that repeat factor is 1 affirmation/deny is carried out in its requirement.

In one aspect, first time of confirming/denying and frequency location depend on the corresponding packet or the time and the frequency location of data allocations.For example, the transfer of data at subframe (or Resource Block) K place, the first corresponding transmission of confirming/denying is to use the subframe K+4 (for example, the sub-piece 480 of resource) of resource A.Affirmation/the time and the frequency location of denying of the follow-up repetition of identical data transmission depends on the time and the frequency location of identical packet or data allocations.For example, transfer of data at subframe K, the subframe K+5 that is transmitted as use resource B that second of identical data transmission is confirmed/denied (for example, the sub-piece 482 of resource), transfer of data at subframe K, the subframe K+6 (for example, the sub-piece 484 of resource) that is transmitted as use resource C that second of identical data transmission is confirmed/denied, or the like.Resource A, B and C can express times and frequency, coding, channel etc.

The correspondence of HARQ process is confirmed, confirms/deny to use the same tone group 466 of first transmission that is used to confirm/deny to transmit, and sets of tones 466 is quadrature in time.In one aspect, corresponding to the time started position of the affirmation channel of HARQ process skew is arranged, as shown in 470.For this example, first transmission confirming/deny is used tone 466 and corresponding to the symbol 452 of the affirmation 0 of HARQ process 0; Symbol 454 is used in affirmation 1 corresponding to HARQ process 1; Symbol 456 is used in affirmation 2 corresponding to HARQ process 2; Symbol 458 is used in affirmation 3 corresponding to HARQ process 3; Symbol 460 is used in affirmation 4 corresponding to HARQ process 4.

For the HARQ that confirms/deny, the affirmation of corresponding HARQ process uses acknowledgement channel to transmit, and described acknowledgement channel is used different frequency locations between the transmission period of each repetition.For example, the UE that receives the data of HARQ process 0 requires confirming/deny triplicate, and corresponding affirmation/deny (for example, confirming 0) uses the sub-piece 480 of first transmission to transmit, and uses sub-piece 482 and 484 to come duplicate acknowledgment/deny transmission.The sub-piece frequency that is used to transmit the affirmation of repetition/deny depends on that the frequency that is used for corresponding HARQ process that Resource Block uses adds deviant.Deviant must be at least greater than the value of the tone of first transmission that is used to confirm/deny.Therefore, the sets of tones that is used for sub-piece 480,482 and 484 illustrates respectively 462,464 and 466.In one aspect, first 480 resource time and the frequency location of confirming transmission mode (for example can impliedly depend on corresponding packet, in 402, use shared channel and HARQ process 0 to be transmitted) time and frequency location, the subsequent block 482 of affirmation transmission mode and 484 time and frequency location impliedly depend on the time and the frequency location of the packet (for example, using HARQ process 0 to be transmitted) of corresponding use skew in 402.

In yet another aspect, first 480 time and the frequency location of confirming transmission mode can be (for example impliedly to depend on corresponding data allocations bag, the use control channel) time and frequency location, the subsequent block 482 of affirmation transmission mode and 484 time and frequency location impliedly depend on the time and the frequency location of corresponding data allocations bag.

With reference to figure 5-6, confirm/deny the relevant method of mechanism of the HARQ that retransmits.Though in order to make explanation simpler; and this method is described as a series of action; but should be appreciated that and understand be; these methods are the restriction of sequence of movement not; because; according to theme required for protection, some actions can by different order take place and/or with shown in the application and other action of describing take place simultaneously.For example, it should be understood by one skilled in the art that and understand that a method also can be expressed as a series of state and incidents of being mutually related, as in state diagram.In addition, all be essential if realization according to the method for theme required for protection, is not the everything of depicting.
