Technical field

The present invention relates to wireless communication field, relate in particular to a kind of scheduling and report method, system and equipment of ascending control information.

Background technology

Ascending control channel (PUCCH) is used for the later ascending control information of transmitting synchronous (UCI) in Long Term Evolution (LTE) system, and the ascending control information of the last transmission of PUCCH mainly comprises cycle channel quality indication (CQI) information of uplink scheduling request (SR), down mixing self-retransmission request affirmation (HARQ-ACK) information and terminal (UE).Wherein, according to the difference of distributing the PUCCH resource, descending HARQ-ACK information can be further divided into semi-continuous scheduling HARQ-ACK information, dynamic dispatching HARQ-ACK information and acknowledgement/non-acknowledgement and repeat (ACK/NACK repetition) information three parts.The resource location of UCI information and this information correspondence, configuration parameter and the configuration of resource indication parameter are as shown in Figure 1.

PUCCH takies resource and mainly comprises two parts in the sub-frame of uplink, and a part is the resource that PUCCH form (format) 1/1a/1b takies, and another part is the resource that PUCCH format2/2a/2b takies.

The resource that PUCCH format1/1a/1b takies is as follows:

A part is the shared resource of PUCCH of dynamic dispatching ACK/NACK feedback; Another part is meant and is used to transmit specific schedule request (D-SR), semi-continuous scheduling ACK/NACK and the required resource of ACK/NACK repetition in the sub-frame of uplink that physical layer is expressed as parameter Be the cell-level parameter, calculation expression is:

$N_{\mathrm{PUCCH}}^{\left(1\right)}=n_{\mathrm{PUCCH},\mathrm{persis}}^{\left(1\right)}+n_{\mathrm{PUCCH},\mathrm{schreq}}^{\left(1\right)}+n_{\mathrm{PUCCH},\mathrm{repetition}}^{\left(1\right)};$

Wherein:

Represent to be used in the sub-frame of uplink PUCCH (1) the resource number of semi-continuous scheduling feedback;

Represent to be used to send in the sub-frame of uplink PUCCH (1) the resource number of dispatch request;

PUCCH (1) the resource number that expression ACK/NACK repetition uses.

For PUCCH format 1/1a/1b, the UE that a Physical Resource Block (PRB) can carry counts N _{User_perPRB}Calculate according to following formula:

$N_{\mathrm{user}\_\mathrm{perPRB}}=L_{\mathrm{CS}\_\mathrm{PUCCH}}/{\mathrm{\Δ}}_{\mathrm{shift}}^{\mathrm{PUCCH}}\·N_{\mathrm{othogonal}\_\mathrm{seq}}=36/{\mathrm{\Δ}}_{\mathrm{shift}}^{\mathrm{PUCCH}}$

Be the cyclic shift interval of cyclically shifted sequences, can value 1,2,3, the result according to link simulation provides gets If UE counts more at least and can get

According to following formula:

If

N then _{User_perPRB}=36;

If

N then _{User_perPRB}=18;

If

N then _{User_perPRB}=12.

The resource that PUCCH format2/2a/2b takies is as follows:

Be used to transmit the required resource of CQI in the sub-frame of uplink, the physical layer parameter

Expression, the cycle CQI sets of transmission resources that the sub-district is reserved depend on that the UE number that needs life cycle CQI feedback in the system (uses Operational Management System (O﹠amp; M) Pei Zhi parameter N _{UE_CONNECT}Expression) and the CQI feedback cycle of UE (use O﹠amp; The parameter N of M configuration _PExpression) relevant.

For transmission SR information on PUCCH, it is actually transmission D-SR information; For the UE that has disposed the D-SR resource, the resource of its D-SR is periodically to repeat, and can dispose the number of transmissions DSR_TRAN_MAX of maximum D-SR by rrc layer, guarantees the reliability of D-SR.

Usually in the PUCCH transmitted over resources, when certain UE exists PUCCH resource and PUSCH resource simultaneously in a subframe, the information on this PUCCH resource will be gone shared channel (PUSCH) physically and be gone up transmission for the descending HARQ-ACK information of UE.Because descending scheduling is supported two class scheduling modes: the HARQ-ACK of semi-continuous scheduling HARQ-ACK and dynamic dispatching.For descending semi-continuous scheduling HARQ-ACK mode, the PUCCH resource of using is disposed by the base station rrc layer fully, descending dynamic dispatching HARQ-ACK mode, the CCE resource index that the resource of use is used according to the descending scheduling signaling of timing Design, the configuration of base station rrc layer and this dynamic dispatching of dispatch determines jointly.And, in order to solve the reliability of up covering deficiency or HARQ-ACK transmission, can being guaranteed by the transmission that repeats of descending HARQ-ACK information, the employed resource of ACK/NACK repetition, number of repetition etc. dispose by the base station rrc layer.

In realizing process of the present invention, the inventor finds to exist in the prior art following technical problem:

According to the analysis of existing scheme, the D-SR in the UCI information can dispose the number of transmissions DSR_TRAN_MAX of maximum D-SR by rrc layer as can be known, guarantees the transmission reliability of D-SR, and HARQ-ACK can guarantee its transmission reliability by ACK/NACK repetition.And the present concrete scheme that does not guarantee cycle CQI message transmission reliability, when PUCCH covered deficiency, cycle CQI transmission of Information performance can not get guaranteeing.

In order to improve the transmission performance of ascending control information, the embodiment of the invention provides a kind of scheduling and report method of ascending control information, in this method, the base station is after determining to need to adopt semi-continuous scheduling (SPS) mode dispatch terminal by Physical Uplink Shared Channel (PUSCH) periodicity reporting uplink control information, dispatch terminal is by PUSCH periodicity reporting uplink control information, and terminal is passed through periodically reporting uplink control information of PUSCH according to the scheduling of base station.

Referring to Fig. 2, the dispatching method of the ascending control information that the embodiment of the invention provides specifically may further comprise the steps:

Step 20: the base station determines that terminal carries out ascending control information by PUSCH and periodically report, the up SPS parameter value that is adopted, and the configuration signal that will carry described up SPS parameter value sends to terminal;

Step 21: the base station determines that terminal carries out ascending control information by PUSCH and periodically report, the MCS grade and the resource location that are adopted, and send the dispatch of the information carry described MCS grade and described resource location to terminal, carry out ascending control information according to this dispatch to the base station with triggering terminal and periodically report.

Preferable, before step 20, the base station is according to the load condition and/or the disturbed condition of Physical Uplink Control Channel (PUCCH), and the PUSCH resource bearing that determines whether to enable SPS is the scheme of ascending control information periodically; For example, when the load of PUCCH has reached predefined load door limit value, determine to enable this scheme; Perhaps, when the IoT value of disturbed condition of expression PUCCH has reached predefined IoT threshold value, determine to enable this scheme; Perhaps, when the IoT value that has reached the disturbed condition of predefined load door limit value and expression PUCCH at the load of PUCCH has reached predefined IoT threshold value, determine to enable this scheme.

Then in the step 20, the base station determines that terminal carries out ascending control information by PUSCH and periodically report after determining to enable described scheme, the up SPS parameter value that is adopted, and the configuration signal that will carry described up SPS parameter value sends to terminal.

Preferable, after described scheme is determined to enable in the base station and before definite described up SPS parameter value, the base station determines whether described terminal is fit to adopt described scheme and whether needs are the up SPS parameter value of described terminal configuration; For example, when passing through the PUCCH reporting uplink control information, terminal on the employed subframe, when idle available resources are arranged, determines that described terminal is fit to adopt described scheme, otherwise, determine that described terminal is not suitable for adopting described scheme; Adopt the natural period by the PUSCH reporting uplink control information in terminal, in the time of can not producing resource contention, determine not need to be the up SPS parameter value of described terminal configuration, otherwise, need redefine report cycle, make terminal adopt this report cycle can not produce resource contention, and this report cycle disposed to terminal by up SPS parameter value that this natural period is terminal employed cycle when the PUCCH reporting uplink control information originally by the PUSCH reporting uplink control information.

Then in the step 20, the base station be fit to adopt described scheme and needs for described terminal configuration behind the up SPS parameter value in definite described terminal, determine that terminal carries out ascending control information by PUSCH and periodically report, the up SPS parameter value that is adopted, and the configuration signal that will carry described up SPS parameter value sends to terminal.

As a kind of situation, do not have other that need to adopt that the SPS mode dispatches when professional in terminal, the base station use described configuration signal and described dispatch only dispatch terminal periodically report described ascending control information by PUSCH.

At this moment, described up SPS parameter value comprises up half-persistence scheduling resources spacing value, and this up half-persistence scheduling resources spacing value is: terminal is in the time cycle value of carrying out on the PUCCH giving the correct time and being adopted on the ascending control information periodicity.

As a kind of situation, do not have other that need to adopt that the SPS mode dispatches when professional in terminal, the base station use described configuration signal and described dispatch only dispatch terminal periodically report described ascending control information by PUSCH.

At this moment, described up SPS parameter value comprises up half-persistence scheduling resources spacing value, and this up half-persistence scheduling resources spacing value is: terminal is in the time cycle value of carrying out on the PUCCH giving the correct time and being adopted on the ascending control information periodicity.

As another kind of situation, have other that need to adopt that the SPS mode dispatches when professional in described terminal, the base station also use described configuration signal and described dispatch simultaneously dispatch terminal periodically report described other professional data by PUSCH.

At this moment, terminal is transmitted described other professional data also in the resource at described resource location place.

Accordingly, described up SPS parameter value comprises up half-persistence scheduling resources spacing value, and this up half-persistence scheduling resources spacing value is: the time cycle value that is adopted during the data of terminal described business of cyclical transmission on PUSCH.

Concrete, terminal can adopt hole knockout, the described ascending control information of transmitted over resources and described other professional data at described resource location place.

In this method, described ascending control information is: the HARQ-ACK feedback information of CQI information or D-SR information or SPS.

Below the present invention is specifically described:

At the LTE system, when ascending control channel covers deficiency, the problem that cycle CQI transmission performance can not get guaranteeing, the present invention has provided a kind of method and device that promotes the ascending control channel reliability, it is the method for the PUSCH resource bearing cycle CQI information of SPS, guarantee the reliability of its cycle CQI, simultaneously, the method can expand to has periodic other UCI information.This scheme both had been applicable to that the FDD system also was applicable to the TDD system.

The basic realization flow of the PUSCH resource bearing cycle CQI information scheme of SPS is shown in Fig. 4 A:

The first step: the PUCCH resource management module of base station MAC layer carries out the activation decision-making of the PUSCH resource bearing cycle CQI information of the SPS that the present invention proposes according to historical PUCCH load condition, disturbed condition, determines current this scheme that whether needs to enable;

Second step: after the scheme of the PUSCH resource bearing cycle CQI information of determining activation SPS, rrc layer determines according to each UE actual conditions whether current UE is fit to adopt this programme and whether needs dispose corresponding semi-continuous scheduling parameter, if need configuration, then determine parameters such as semi-continuous resource cycle according to the transmission QoS demand of cycle CQI, finish the configuration of IE (Information Element, information unit) SPS-Config;

The 3rd step: the MAC layer carries out the PUSCH resource bearing cycle CQI information activation decision-making of SPS according to designed rule, when activating semi-continuous resource, determine TB size simultaneously according to the loaded service feature, determine MCS and the Uplink Shared Channel resource of being distributed according to the channel condition of UE, finish the activation of semi-continuous resource.

Introduce the concrete scheme in each step of method of the PUSCH resource bearing cycle CQI information of SPS below in detail:

The first step designs the activation mechanism of scheme provided by the present invention;

Among the above-mentioned IE, the implication of each parameter such as following table 1:

Table 1

When the parameters of configuration IE SPS-Config, the configuration at interval of up-downgoing half-persistence scheduling resources depends on the cycle of the cycle CQI of current UE, the configuration of this parameter will influence ageing that UE cycle CQI reports, and the configuration at interval of semi-continuous resource need take into account the arrival feature of business data packet and the cycle size of cycle CQI.

UE carries out resource allocation and gets final product if when only having cycle CQI, then only need be thought of as cycle CQI;

If when there is cycle CQI simultaneously in UE and adopts semi-continuous scheduling professional, need take all factors into consideration cycle CQI and other packets arrival feature.As: the voice packet arrival interval of VOIP activation of service phase is about 20ms, and the cycle of general CQI is taken as 20ms, then can dispose half-persistence scheduling resources and be spaced apart 20ms this moment.

In the 3rd step, the MAC layer is used the solution of the present invention;

At rrc layer successfully is that the MAC layer just can carry out the decision-making of semi-continuous resource active as required after UE had disposed relevant information among the IE SPS-Config when carrying out data dispatch.At this moment, the eNB side needn't be the resource of UE configuration cycle CQI, only being required to be cycle CQI dispatches according to the semi-continuous scheduling mode and gets final product, the call relation of the PUSCH resource bearing cycle CQI information of SPS is shown in Fig. 4 B, the base station is at subframe n, after carrying the DCI format0 use SPS-RNTI scrambling of MCS grade and resource location information, send to UE by PDCCH, UE obtains the MCS grade and the resource location information of PDCCH carrying in subframe n+4 demodulation, and use the PRB resource at this MCS grade and this resource location place to report CQI information to the base station, follow-uply carry out reporting of a CQI information to the base station every 20 subframes.

The design of concrete activation mechanism is relevant with the target of algorithm design, semi-continuous scheduling is activated by the PDCCH of SPS C-RNTI scrambling in the base station, determine the MCS of UE and PRB (PhysicalResource Block) resource of distribution simultaneously, the PRB of MCS and distribution has determined the Data-carrying ability of current PRB, i.e. TB size.According to the regulation of LTE standard, TB size obtains later on according to the form that the PRB number that is distributed and the current MCS grade of UE are searched standard definition, determines that therefore TB size promptly determines the current MCS grade of UE, is the PRB number of resources of UE distribution.

(a) determining of TB size: definite feature that needs to consider the semi-continuous scheduling transport service of the data volume size TB size of the each transmission bearer of semi-continuous resource, this semi-continuous resource configuration at interval.

When if only there is cycle CQI in UE, then only need be thought of as the bit number of cycle CQI, about 20 bits;

If when there was cycle CQI simultaneously in UE and adopts semi-continuous scheduling professional, cycle CQI adopted hole knockout to transmit at PUSCH, on the one hand, only considers to adopt the TBsize of semi-continuous scheduling business; On the other hand, cycle CQI as a kind of business, is participated in resource allocation with data, at this moment, need the corporate data amount of consideration cycle CQI and other packets, determine TBsize.

(b) determining of MCS grade: the MCS grade of determining support according to the Channel Transmission condition of UE.For up, the SRS (Sounding Reference signal, detection reference signal) that the base station sends UE carries out channel quality information, and (the current MCS grade that can support of UE is determined in Channel Quality Information, measurement CQI) and correction.In addition, because the MCS grade generally can not change in the semi-continuous scheduling process, therefore up CQI information used herein all is through the later information of smoothing processing.

(c) determining of PRB resource location:, just can determine the PRB number of UE needs when activating semi-continuous resource and the original position of PRB based on the demand of TB size, the MCS grade of the current support of UE.Employed subframe when UE uses the PRB that determines and reports CQI information by PUCCH is originally carried out CQI property information cycle by PUSCH and is reported.
