Description

A kind of ascending control information UCI transmission and method of reseptance and equipment

Technical field

The present invention relates to wireless communication technology field, relate in particular to a kind of ascending control information UCI transmission and method of reseptance and equipment.

Background technology

In Long Term Evolution (Long Term Evolution, LTE) system, the ascending control information (Uplink Control Information, UCI) of UE feeding back downlink carrier wave in sub-frame of uplink.

UCI comprises and mainly comprises three category informations: cycle and aperiodic channel status information, channel condition information specifically comprise in following three parameters appoint several: CQI (Channel Quality Indicator, channel quality indication)/PMI (Precoding Matrix Indicator, pre-coding matrix index)/RI (Rank Indication, order indication); Positive acknowledgement ACK (Acknowledgment)/Negative Acknowledgement NACK (Negative Acknowledgment) information; SR (Scheduling Request, dispatch request) information.

In LTE Rel-8 system, the transmission mechanism of UCI is, UCI can be at PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) on transmit, also can be in PUSCH (Physical Uplink Share Channel, Physical Uplink Shared Channel) and data-reusing transmission.In order to keep LTE system single-carrier property, LTE Rel-8 system does not support same UE on PUCCH and PUSCH, to transmit UCI in a sub-frame of uplink simultaneously.Adopt PUCCH transmission cycle CQI/PMI/RI, ACK/NACK and SR to only occur in the sub-frame of uplink that does not have PUSCH transmission, in the sub-frame of uplink that exists PUSCH to transmit, CQI/PMI/RI, ACK/NACK feedback information need carry out multiplexing transmission with data on PUSCH, and SR transmits at PUSCH as MAC PDU.

In LTE Rel-8 system, the concrete transmission mechanism of UCI is described in detail as follows:

If when UE only feeds back the category information in above-mentioned UCI in current sub-frame of uplink, can, according to system configuration and concrete scheduling situation, on PUCCH, transmit or transmit on PUCCH.For the situation of only feeding back CQI/PMI/RI, if cycle CQI/PMI/RI reports, generally on PUCCH, transmit, if aperiodic, CQI/PMI/RI reported, generally on PUSCH, transmit.When aperiodic, CQI/PMI/RI transmitted in PUSCH, trigger by the 1bit CQI request information in UL grant (uplink authorization).UE detects that in UL grant, this information bit is set to 1, organizes relevant CQI/PMI/RI to be multiplexed in PUSCH according to pre-configured feedback model and transmits, otherwise do not transmit.

While transmission on PUCCH, utilize the transformat of the different transmission requirements of correspondence that define to transmit on PUCCH.When ACK/NACK transmits separately on PUCCH, can adopt transformat PUCCH format 1a/1b; When SR transmits separately on PUCCH, adopt transformat PUCCH format 1; Reporting according to pre-configured report cycle of cycle CQI/PMI/RI transmitted in PUCCH, can adopt transformat PUCCH format 2/2a/2b.

While transmission with data-reusing on PUSCH, as shown in Figure 1, the resource that CQI/PMI transmits on PUSCH is according to the feedback information length of CQI/PMI and configure reserved, data division does not take the transfer resource of CQI/PMI, RI information is by mapping that upstream data is punched, be close to the first time domains of four row symbols of ACK/NACK after frequency domain from low frequency to high frequency, shine upon.ACK/NACK after reference symbol both sides are by first time domain frequency domain, from low frequency to high frequency, shine upon, SR transmits on PUSCH as MAC PDU.

In a sub-frame of uplink, also may there is periodic spy reference signal (SRS in UE, sounding reference symbol), the relevant parameter of SRS transmission (comprises the cycle, SRS bandwidth etc.) be that UE is exclusive, and by the semi-static configuration in base station, can only on last the SC-FDMA symbol in the sub-frame of uplink that has configured SRS transmission, send.

In the upper UCI of PUSCH dissimilar information and with above-mentioned SRS time transmission mechanism as follows:

Because the PUSCH physical resource shining upon when the upper defined good above-mentioned all kinds of UCI communication of PUSCH, transmission when transmission and any number of type UCI information when therefore supporting above-mentioned all types UCI information when the upper transmission of PUSCH.CQI/PMI/RI feedback information, ACK/NACK feedback information, SR and SRS information in same sub-frame of uplink in the time that PUSCH transmits simultaneously, the reserved transmitting SRS that is used for of last symbol in sub-frame of uplink, data message according to SRS transmission carry out rate-matched.

When cycle CQI/PMI/RI and aperiodic CQI/PMI/RI report while occurring in same sub-frame of uplink, UE abandons cycle CQI/PMI/RI and reports, and only reports CQI/PMI/RI aperiodic at PUSCH.

In the upper UCI of PUCCH dissimilar information and with above-mentioned SRS time transmission mechanism as follows:

1) when feeding back ACK/NACK and SR

When LTE Rel-8 supports ACK/NACK and SR, transmission adopts transformat PUCCH format 1 simultaneously while transmission, sends ACK/NACK information on the channel resource of SR.

2) when feeding back ACK/NACK and cycle CQI/PMI/RI

Whether base station can support ACK/NACK and cycle CQI/PMI/RI to transmit in PUCCH by the semi-static configuration UE of parameter s imultaneousAckNackAndCQI.

When this parameter is False, do not support to transmit simultaneously,, in the time that ACK/NACK and cycle CQI/PMI/RI need to adopt PUCCH transmission in same sub-frame of uplink, UE will lose cycle CQI/PMI/RI, feeding back ACK/NACK.

When this parameter is True, support transmission simultaneously, the corresponding 2 bit transfer information of the number of ACK in the ACK/NACK feedback information of 1 gained of tabling look-up when 1 bit ACK/NACK feedback information when ACK/NACK information now represents a data packet dispatching or multiple data packet dispatching.

The corresponding respective transmissions information of table 1 more than ACK/NACK feedback information

Under conventional CP, adopt transformat PUCCH format 2a/2b, ACK/NACK information is mapped in secondary series pilot resources and transmits.Under expansion CP, adopt PUCCH format 2, ACK/NACK information and cycle CQI/PMI/RI information carry out being mapped in respective resources after combined coding.

3) when feedback cycle CQI/PMI/RI and SR

When SR and cycle CQI/PMI/RI are in the time that the same sub-frame of uplink of PUCCH bumps, UE only reports SR, adopts transformat PUCCH format 1, abandons cycle CQI/PMI/RI.

4) when feeding back ACK/NACK, cycle CQI/PMI/RI and SR

UE on PUCCH by 1) mode reports SR and ACK/NACK, abandons cycle CQI/PMI/RI.

5) feeding back ACK/NACK and/or SR and SRS

Whether base station can support in same sub-frame of uplink SRS and ACK/NACK and/or SR to transmit at PUCCH by the semi-static configuration UE of parameter ackNackSRS-SimultaneousTransimission simultaneously.

If this parameter is False, need in same subframe transferring ACK/NACK and/or SR and SRS on PUCCH time, UE will abandon SRS, feeding back ACK/NACK and/or SR.

If this parameter is True, UE can be in a subframe on PUCCH transmitting SRS and ACK/NACK and/or SR simultaneously, use transformat shortened PUCCH format 1/1a/1b to transmit, so-called shortened PUCCH i.e. not transferring ACK/NACK and/or SR on last symbol in this subframe, and UE is by the transmitting SRS on this symbol that is configured according to predetermined.

It should be noted that, parameter ackNackSRS-SimultaneousTransimission is community exclusive (Cell-specific) parameter, in the time having configured SRS and ACK/NACK and/or SR and transmitted simultaneously, in the sub-frame of uplink that needs transmitting SRS of system configuration, all UE can only use shortened PUCCH format 1/1a/1b transferring ACK/NACK and/or SR in this subframe, no matter whether this UE is configured in transmitting SRS in this subframe.

For LTE-A (Long Term Evolution-Adavance) system, also claim long-term evolution multi-carrier system, for supporting the system bandwidth wider than LTE system, such as 100MHz, may be a frequency spectrum that directly distributes 100M bandwidth, as shown in Figure 2; One may be to distribute to some spectrum aggregatings of existing system, gather into large bandwidth and supply with long-term evolution multi-carrier system use, now in system, up-downgoing carrier wave can asymmetricly configure, be that user may take N >=1 carrier wave and carries out downlink transfer, M >=1 carrier wave carries out uplink, as shown in Figure 3.

In LTE-A system, base station polymerization multiple descending carriers while sending data to user, UE will feed back the UCI of corresponding multiple descending carriers in a sub-frame of uplink.UCI number of bits of feedback is more, and dissimilar UCI information may not be fed back at a PUCCH channel simultaneously.

LTE-A determines and can support at most 5 carrier waves to carry out polymerization at present, in same sub-frame of uplink, UE need to feed back the UCI information of corresponding multiple descending carriers, the feedback information volume of ACK/NACK and CQI/PMI/RI is larger, for the ease of uplink scheduling, UE also need to send SRS on multiple carrier waves, if transmission mechanism transmits still according to LTE Rel-8 time, the probability that SRS and cycle CQI/PMI/RI are dropped is larger, and then base station cannot obtain the channel conditions of uplink and downlink carrier wave in time, thus impact scheduling.

In addition, consider ACK/NACK information in the reliability of PUCCH transmission higher than the transmission reliability on PUSCH, and the punching transmission on data on PUSCH of many bit ACK/nack messages becomes large to the impact of data transmission performance, and when LTE Rel-8 system, transmission plan is no longer applicable to LTE-A system.

In order to keep compatible with LTE system, LTE-A system is supported the transmission of UCI at PUCCH and/or PUSCH.In addition, in LTE-A system, also support PUCCH and PUSCH in same sub-frame of uplink to a UE in transmission.

In order to support ACK/NACK and SRS to transmit in PUCCH, LTE-A system also may define the shortened PUCCH format based on DFT-S-OFDM (discrete Fourier transform-spread-orthogonal frequency division multiplexing, the OFDM of discrete Fourier transform (DFT) expansion).

When UE has configured PUCCH and PUSCH in the time that a sub-frame of uplink transmits simultaneously, dissimilar UCI information can be transmitted at PUCCH and PUSCH simultaneously, thereby avoid abandoning certain UCI information or SRS transmission problem due to what the collision between dissimilar UCI information and between UCI information and SRS information caused, improve system call accuracy and also guarantee transmission reliability.

But UE has configured PUCCH and PUSCH while transmitting simultaneously, dissimilar UCI information how on PUCCH and PUSCH transmission simultaneously also there is no clear and definite scheme.

Embodiment

Below in conjunction with drawings and Examples, the method for user terminal UE provided by the invention and transmitting uplink control information UCI thereof is illustrated in greater detail.

In LTE-A system, UE is supported in a sub-frame of uplink and on PUCCH and PUSCH, transmits UCI simultaneously, but how simultaneously for transmission does not provide clear and definite scheme.The present invention has provided the scheme that a kind of UCI transmits on PUCCH and PUSCH simultaneously.As shown in Figure 4, ascending control information UCI transmission method provided by the invention comprises step:

Step S401, user terminal UE determines the up-link carrier at the Physical Uplink Control Channel PUCCH place of transmission UCI, and the up-link carrier at the Physical Uplink Shared Channel PUSCH place of transmission UCI;

In LTE-A system, UE carries out signaling scheduling and business transmission on multiple carrier waves of polymerization or activation at the same time.The angle of distributing from resource, at present standard in discussing by the configurable limit of some ascending resources on certain up-link carrier, and define main carrier (Primary Component Carrier, PCC) concept, when UE uses in multiple member carriers of polymerization or activation, member carrier beyond main carrier is auxiliary carrier wave (Subsidiary Component Carrier, SCC).

Step S402, UE, at the up-link carrier at the PUCCH place of transmission UCI, transmits positive acknowledgement ACK/ Negative Acknowledgement nack message by PUCCH;

While transmission with data-reusing on PUSCH due to ACK/NACK information, need to, by Fig. 1 mode to the upstream data mapping of punching, therefore can take data transmission resources.In addition, ACK/NACK has relatively high expectations to transmission performance, the transmission performance higher than PUSCH to the transmission performance of ACK/NACK of PUCCH.The present invention is in current sub-frame of uplink, need in feedback UCI when ACK/NACK information, at the up-link carrier at the PUCCH place of transmission UCI, adopt PUCCH transferring ACK/nack message, when avoiding taking too many data transmission resources, guarantee the transmission performance of ACK/NACK information.

Step S403, UE is at the up-link carrier at the PUSCH place of transmission UCI, by PUSCH transmitting channel state information.

Channel condition information comprises channel quality indicator (CQI), pre-coding matrix index PMI and order indication RI, and wherein CQI and PMI information can report according to the pattern of system configuration simultaneously, also can only report CQI information; RI information determines whether to report according to different transmission mode, and therefore at current sub-frame of uplink, what need feedback may be one or more in these three parameters.In the present embodiment, channel condition information comprises in CQI, PMI, RI severally arbitrarily, below channel condition information is represented with CQI/PMI/RI.

In said method of the present invention, ACK/NACK information priority is transmitted on PUCCH, to reduce the taking of data transmission resources, and guarantee the reliability of ACK/NACK transmission.Report for CQI/PMI/RI, no matter be periodically or aperiodicity CQI/PMI/RI reports, all CQI/PMI/RI is preferentially transmitted on PUSCH, with the problem that abandons of avoiding transmitting at PUCCH due to multiple UCI and/or SRS simultaneously.

Preferably, also comprise step S404, need to send dispatch request SR in current sub-frame of uplink time, described UE is at the up-link carrier at the PUSCH place of described transmission UCI, with the form transmission SR of media access control protocol data unit MAC PDU.

SR is fixed to the upper transmission of PUSCH by the present invention, while having avoided transmitting on PUCCH and other type UCI information bump and abandon the problem of respective feedback information, improved scheduling accuracy.

The up-link carrier at the PUCCH place of above-mentioned transmission UCI, is specially the up main carrier PCC in multiple up-link carriers of described UE polymerization or activation; The up-link carrier at the PUSCH place of described transmission UCI is the up main carrier PCC in multiple up-link carriers of described UE polymerization or activation or a upstream auxiliary carriers SCC.

In the sub-frame of uplink of UE, also may there is periodic spy reference signal SRS, how specifically to transmit in conjunction with SRS, in the step S402 of said method of the present invention, for different situations, specifically transferring ACK/nack message in the following way:

1) if current sub-frame of uplink is to have the sub-frame of uplink of visiting reference signal SRS transmission, and described UE supports SRS and ACK/NACK information to transmit simultaneously;

UE, at the up-link carrier at the PUCCH place of described transmission UCI, adopts the PUCCH transformat transferring ACK/nack message of the brachymemma that is reserved with SRS transmission location, and SRS sends at last symbol of current sub-frame of uplink according to predetermined configuration.Therefore realize while transferring ACK/nack message and SRS on PUCCH.

If in current sub-frame of uplink, UE has transfer of data at the up-link carrier at the PUSCH place of described transmission UCI, and the transfer of data on PUSCH is carried out rate-matched according to the predetermined configuration of described SRS.

2) if current sub-frame of uplink is to have the sub-frame of uplink of visiting reference signal SRS transmission, and described UE does not support SRS and ACK/NACK information to transmit simultaneously;

UE is at the up-link carrier at the PUCCH place of described transmission UCI, adopt the not conventional PUCCH transformat transferring ACK/nack message of reserved SRS transmission location, the up-link carrier at the PUCCH place of described transmission UCI does not send SRS at current sub-frame of uplink, i.e. the transmission of SRS on PUCCH is dropped.

If in current sub-frame of uplink, UE has transfer of data at the up-link carrier at the PUSCH place of described transmission UCI, and the transfer of data on PUSCH is carried out rate-matched according to the predetermined configuration of described SRS.

Because UE supports UCI transmission simultaneously on PUCCH and PUSCH.Therefore, when SRS is in the time that the transmission of the up-link carrier at the PUCCH place of transmission UCI is dropped, if there is SRS transmission in current sub-frame of uplink on the up-link carrier at PUSCH place that transmits UCI, can press an in the end symbol transmission of predetermined configuration on the PUSCH of this carrier wave.Certainly also transmitting SRS on PUSCH not.

3) if current sub-frame of uplink is without the sub-frame of uplink of visiting reference signal SRS transmission;

UE, at the up-link carrier at the PUCCH place of described transmission UCI, adopts the not conventional PUCCH transformat transferring ACK/nack message of reserved SRS transmission location.

Wherein, in above process, the predetermined configuration information of SRS can comprise cycle and the transmission bandwidth of SRS, concrete, can determine whether current sub-frame of uplink is to dispose the sub-frame of uplink of visiting reference signal SRS transmission by the configuration cycle of SRS.

In the embodiment of the present invention determining that current sub-frame of uplink is when visiting the sub-frame of uplink of reference signal SRS transmission, no matter described UE does not support SRS and ACK/NACK information to transmit simultaneously, still support SRS and ACK/NACK information to transmit simultaneously, all can adopt the not conventional PUCCH transformat transferring ACK/nack message of reserved SRS transmission location.

In existing LTE system UCI transmission mechanism, in the time that UE supports that SRS and ACK/NACK information are transmitted simultaneously, if current sub-frame of uplink is to have the subframe of visiting reference signal SRS transmission, consider that other UE may exist in the PUCCH of current UE transmission bandwidth position SRS transmission, therefore, no matter whether current UE exists SRS transmission at this sub-frame of uplink, UE can adopt the PUCCH transformat of the brachymemma that is reserved with SRS transmission location to transmit described ACK/NACK information.

In addition, in system the configuration of SRS can be cell level can be also carrier-grade.If the configuration of SRS is carrier-grade, may there is different SRS transmission cycle and bandwidth in different up-link carriers, now, consider that the SRS only having while existing dissimilar UCI and SRS information simultaneously to transmit on PUCCH abandons problem, therefore in the present embodiment, whether exist while visiting reference signal SRS transmission at definite current sub-frame of uplink, can be only confirm for the up-link carrier at the PUCCH place of transmission UCI.

Provide below according to the above-mentioned ascending control information UCI of the present invention transmission method preferred embodiment.

In the time that UE in LTE-A is supported in a sub-frame of uplink and adopts PUCCH and PUSCH transmission UCI simultaneously, first UE determines the up-link carrier A at PUCCH place of transmission UCI and the up-link carrier B at the PUSCH place of transmission UCI.

Wherein up-link carrier A is the up main carrier PCC in multiple up-link carriers of UE polymerization or activation, up-link carrier B can be the up main carrier PCC in multiple up-link carriers of UE polymerization or activation, also can be a upstream auxiliary carriers SCC in multiple up-link carriers of UE polymerization or activation.

Determine after up-link carrier A and up-link carrier B, UE feeds back UCI by following flow process:

1), if in current sub-frame of uplink, there is spy reference signal SRS transmission at the up-link carrier A at the PUCCH place of transmitting UCI;

In the present embodiment, will there is the sub-frame of uplink of visiting reference signal SRS transmission to be called system SRS subframe, will be called nonsystematic SRS subframe without the sub-frame of uplink of visiting reference signal SRS transmission.If current sub-frame of uplink is system SRS subframe, illustrate that last symbol of this subframe is used for sending SRS.The configuration of SRS can be that cell level (cell-specific) can be also (CC-specific) of carrier-grade, if cell level,, in system SRS subframe, on the up-link carrier of each UE configuration or activation, there is SRS transmission; If carrier-grade,, in system SRS subframe, may on one or more up-link carriers, there is SRS transmission.

If there is ACK/NACK information feedback and do not have the feedback of CQI/PMI/RI in UE 1. in current sub-frame of uplink;

It is True that ★ works as higher level parameters ackNackSRS-SimultaneousTransimission, illustrate and support SRS and ACK/NACK information to transmit simultaneously, UE is at the up-link carrier A at the PUCCH place of transmission UCI, by being reserved with the PUCCH transformat feeding back ACK/nack message of brachymemma of SRS transmission location, SRS sends at last symbol of up-link carrier A according to predetermined configuration; The transfer of data of PUSCH on the up-link carrier B at the PUSCH place of transmission UCI is carried out rate-matched according to the SRS transmission of predetermined configuration,, if up-link carrier B exists SRS transmission, the transfer of data of the PUSCH on this carrier wave is carried out rate-matched according to the transmission bandwidth of SRS; If up-link carrier does not exist SRS transmission, the PUSCH on this carrier wave only transmits data.

The PUCCH transformat of above-mentioned brachymemma in the present embodiment can adopt in following transformat any:

Shortened PUCCH format 1 under the conventional CP stipulating in LTE Rel-8 system;

Shortened PUCCH format 1a under the conventional CP stipulating in LTE Rel-8 system;

Shortened PUCCH format 1b under the conventional CP stipulating in LTE Rel-8 system;

The concrete transformat of Shortened PUCCH format 1/1a/1b under the conventional CP stipulating in LTE Rel-8 system as shown in Figure 5;

Shortened PUCCH format 1 under the expansion CP stipulating in LTE Rel-8 system;

Shortened PUCCH format 1a under the expansion CP stipulating in LTE Rel-8 system;

Shortened PUCCH format 1b under the expansion CP stipulating in LTE Rel-8 system;

The concrete transformat of Shortened PUCCH format 1/1a/1b under the expansion CP stipulating in LTE Rel-8 system as shown in Figure 6;

Shortened PUCCH format under the conventional CP of OFDM DFT-S-OFDM based on discrete Fourier transform (DFT) expansion, concrete transformat as shown in Figure 7,

Shortened PUCCH format under the expansion CP of OFDM DFT-S-OFDM based on discrete Fourier transform (DFT) expansion, concrete transformat as shown in Figure 8.
