Specific embodiment

Below in conjunction with attached drawing, the technical solution in the application is described.

The English abbreviation used herein arrived and corresponding full name in English and translator of Chinese are as follows:

In conventional cellular communication system (such as LTE), using based on authorization (Grant- in uplink (Uplink, UL) transmission Based mode), i.e. base station dispatch UE carry out UL transmission resource and relative transmission parameters, such as UL transmission it is used when Domain, frequency domain, airspace resource and MCS.In this case, it when a UE has upstream data to need to send, is sent out first to base station Scheduling request out, base station are based on scheduling request and send scheduling authorization, and then UE is according to resource allocation indicated in scheduling authorization And configured transmission carries out UL transmission.If UE itself is in RRC_IDLE (RRC is idle) state, UE need to be connect at random first Enter (interactive process comprising four message), then could transmit data.Anyway, the UL transmission of above-mentioned Grant-based Process requires more signaling overheads, and these Signalling exchanges inevitably bring delay.

Currently, 3GPP is formulating the 5th generation standard (5 of cellular communication^thGeneration, 5G), the field considered It include mMTC and URLLC in scape.The data that mMTC business generates are usually small data (i.e. each data packet is smaller), according to The UL transmission mode of traditional Grant-based, then the occupied resource of data transmission is handed over much smaller than the signaling before data transmission Mutually money used in (such as Signalling exchange of scheduling request and scheduling authorization process, alternatively, the Signalling exchange of random access procedure) Source, this causes resource utilization low, and especially in the case where there is a large amount of mMTC equipment, system resource will be interacted in large quantities Occupied by signaling；URLLC business need low delay, and the Signalling exchange in the UL transmission process of above-mentioned Grant-based, due to It is related to RRC signaling, delay is very big, therefore the UL transmission mode of tradition Grant-based is also difficult to meet URLLC business Demand.

For these reasons, 5G is introduced in NR (New Radio) exempts to authorize (Grant-free) transmission mode, is used for UL transmission.So-called Grant-free transmission mode refers to when UE has data to need to transmit without to base station requests UL transfer resource, But based on certain money of rule selection one for UL transmission in the preconfigured Grant-free transfer resource pond of base station Source directly carries out UL transmission.In this manner it is possible to the Signalling exchange in the UL transmission process of Grant-based be saved, to reduce Signaling overheads and transmission delay, particularly suitable for parcel transmission and latency sensitive business.

Currently, clear agreement mMTC and URLLC supports Grant-free transmission to 5G-NR standard.In addition, standard is also true It is fixed that used running time-frequency resource, i.e. configuration Grant-free transfer resource pond are transmitted by base station configuration Grant-free.

In order to guarantee the reliability of Grant-free transmission, when 5G-NR standard has agreed to Grant-free transmission at present K re-transmission can be carried out, the value of K is configured by network side.K re-transmission can be the K of the same redundancy versions of same data Secondary repetition, i.e., K times transmission content it is identical, such as transmission be same data RV0；K re-transmission is also possible to same K of one data different redundancy versions, i.e., K time the content transmitted is different, for example, transmission be same data RV0, RV1,RV2,…；K times retransmit be also possible to be above two mode combination, i.e., K time retransmit in both comprising re-transmission data and also including Repeated data, for example, transmission is RV0, RV0 of same data, RV1, RV1 ....Note that it includes just that K re-transmission here, which is, K transmission including biography.

Network side can configure number of retransmissions K to carry out the UE of Grant-free transmission, which is used for entire cell, or uses In one group of UE.However, the channel situation of difference UE may be different, it is most that the K of base station configuration, which may not be for each UE, Excellent.For example, UE preferable for channel conditions is configured with biggish K, then since unnecessary re-transmission is transmitted, cause The waste of Grant-free resource, and easily the Grant-free transmission of other UE is interfered；It is poor for channel conditions UE is configured with lesser K, then due to number of retransmissions deficiency, transmission reliability is caused to reduce.And if network side for each UE into The configuration of row K, then since UE is mobile or channel variation, network side needs constantly reconfigure K, it is clear that can bring bigger Signaling overheads.

Fig. 1 shows a kind of communication system suitable for the application.The communication system includes the network equipment and terminal device, The network equipment is communicated with terminal device by wireless network, when terminal device sends information, the channel radio of terminal device Letter module can obtain the information bit that the network equipment is sent to by channel, these information bits are, for example, the place of terminal device Information bit that reason module generates, being saved from the received or memory module in terminal device of other equipment.

In this application, terminal device can be described as access terminal, user equipment (user equipment, UE), Yong Hudan Member, subscriber station, movement station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless telecom equipment, User agent or user apparatus.Access terminal can be cellular phone, the handheld device with wireless communication function, calculate equipment Or it is connected in other processing equipments, mobile unit, wearable device and the 5G mobile communication system of radio modem User equipment.

The network equipment can be the base in CDMA (code division multiple access, CDMA) system Stand (base transceiver station, BTS), is also possible to wideband code division multiple access (wideband code division Multiple access, WCDMA) base station (node B, NB) in system, it can also be long term evolution (long term Evolution, LTE) evolved base station (evolved node B, eNB) in system, it can also be the base in 5G communication system Stand (gNB), and above-mentioned base station is merely illustrative of, the network equipment can also for relay station, access point, mobile unit, wearable set Standby and other types of equipment.

The above-mentioned communication system for being applicable in the application is merely illustrative of, and the communication system for being applicable in the application is without being limited thereto, example Such as, the quantity of the network equipment and terminal device that include in communication system can also be other quantity.

In the following, will be described in the method provided by the present application for sending and receiving upstream data.

Fig. 2 is a kind of schematic diagram of method for sending upstream data provided by the present application.This method 200 includes:

S201, terminal device determine that N, N are that the terminal device is used for transmission transmission block according to reference information There are preset corresponding relationship, N is to be greater than or wait by the number of transmissions of (transmission block, TB), the reference information and N In 1 integer.

S202, terminal device send N number of upstream data according to authorized transmissions mode is exempted from, which includes described Data and N-1 re-transmission data are passed at the beginning of one of transmission block.

Wherein, retransmitting data can be the repetition for just passing data, be also possible to just pass the similar and different redundancy version of data This (redundancy version, RV).For example, just passing the RV0 that data are transmission blocks, N-1 re-transmission data are just to pass data Repetition, i.e., be all RV0；For another example, the RV0 that data are transmission blocks is just passed, N-1 retransmits other RV that data are transmission blocks, such as RV1,RV2,…；For another example, the RV0 that data are transmission blocks is just passed, N-1 retransmits the repetition or other RV that data are transmission blocks, such as RV0、RV1、RV2、RV2、…。

In the application, the preset corresponding relationship of reference information and N can be network equipments configuration, be also possible to communicate As defined in agreement, human configuration can also be, above-mentioned corresponding relationship can periodically or irregularly update, and the application is to terminal How equipment obtains above-mentioned preset corresponding relationship without limitation.

Reference information can be one or more parameters, be also possible to one or more conditions, the application is to reference information Concrete form and name without limitation.

It should be noted that the corresponding relationship of reference information and N can be it is one-to-one, be also possible to it is one-to-many, can be with It is many-one, for example, reference information A can correspond to N1, N1 and N2 can also be corresponded to, N1 can corresponds to reference information A, can also be with Corresponding reference information B, wherein reference information A and reference information B is different reference information, and N1 and N2 are described in S201 The numerical value of different values in numerical value set.When reference information A corresponds to N1 and N2, terminal device can therefrom select one as The number of transmissions N of transmission block, the application to how from N1 and N2 determine N without limitation.

In S201, as an optional example, terminal device determines N according to reference information from a several value sets, The set of values is combined into the information being preset in terminal device, and it is preconfigured which can be the network equipment, can also be with It is that can also be human configuration as defined in communication protocol, which can periodically or irregularly update, the application couple How terminal device obtains the numerical value set without limitation.

When terminal device has transmission block to need to transmit, terminal device can be selected from numerical value set according to reference information One numerical value, the numerical value represent the number of transmissions for exempting from authorized transmissions, and the number of transmissions may be different under different reference informations, example Such as, when reference information instruction current com-munication environment is not preferably or when the reliability requirement of current transmission is high, terminal device can be with The number of transmissions for exempting from authorized transmissions is reduced, when reference information instruction current com-munication environment is poor or the reliability of current transmission is wanted When asking higher, terminal device can increase the number of transmissions for exempting from authorized transmissions, so as to before not influencing successful receiving rate Put the resource for reducing and exempting from authorized transmissions occupancy.

Optionally, N is less than or equal to K, and K is the maximum transmission times for exempting from authorized transmissions.

The network equipment or communication protocol can specify that terminal device exempt from the maximum transmission times of authorized transmissions, in order to avoid Terminal device occupy excessive resource lead to the wasting of resources and other terminal devices of current communication networks are interfered and So that the transmission reliability of these terminal devices reduces.

It, can be with for example, do not have the presence of emergency data usually in mMTC scene for example, in some communication scenes It is the maximum transmission times for exempting from authorized transmissions that K, which is arranged, and K is the parameter enforced, and current all terminal devices are being pressed Must not exceed K according to the number of transmissions when authorized transmissions mode sends upstream data is exempted from, thereby may be ensured that each terminal device it Between the fairness transmitted.

When channel quality is preferable, the number of transmissions can be a lesser numerical value, when channel quality is bad, transmission time Number can be a biggish numerical value；When the type of service of transmission block requires lower to transmission reliability, the number of transmissions can be with It is a lesser numerical value, when the type of service of transmission block is more demanding to transmission reliability, the number of transmissions can be one Biggish numerical value；The type of service that channel quality and transmission block can also be comprehensively considered selects suitable number from numerical value set Value, so as to improve the level of resources utilization while guaranteeing transmission reliability.

Channel quality can carry out table by the signal-to-noise ratio (signal-noise ratio, SNR) that terminal device measures channel Sign, SNR is bigger, and channel quality is better, and SNR is smaller, and channel quality is poorer.

Fig. 3 shows the schematic diagram of a kind of SNR provided by the present application with the corresponding relationship for the number of transmissions for exempting from authorized transmissions. In Fig. 3, abscissa indicates the value of the SNR for the channel that terminal device measures, and ordinate indicates the value of N, when the value of SNR falls in area Between (a, b) it is interior when, terminal device determine the number of transmissions be 4, when the value of SNR fall in section (c, d) it is interior when, terminal device equipment is true Determining the number of transmissions is 2.

Fig. 3 is merely illustrative of, the application to the concrete form of the corresponding relationship of SNR and the number of transmissions without limitation, SNR It can also be indicated by table with the corresponding relationship of the number of transmissions.

The network equipment can count the SNR, the number of transmissions and transmission reliability of multi-time no authorized transmissions, and be tied according to statistics Fruit determines the corresponding relationship between SNR, the number of transmissions and transmission reliability, and corresponding relationship is allocated to terminal device, in order to Requirement of the terminal device according to transmission block to transmission reliability and the SNR currently measured selection the number of transmissions.Certainly, above-mentioned right Should be related to can also be configured in terminal device by human configuration mode, and how the application obtains reference information to terminal device Without limitation.

Fig. 4 is the schematic diagram for the method that another kind provided by the present application determines N according to channel quality.In Fig. 4, UE1 and UE2 For two different terminal devices from the same base station communication, UE1 is closer apart from base station, UE2 apart from base station away from From farther out, then UE1 can determine present channel quality preferably and select lesser the number of transmissions, and UE2 can determine present channel It is second-rate and select biggish the number of transmissions.

UE1 and UE2 exempts from the resource that authorized transmissions use and can be discontinuous (as shown in Figure 4), is also possible to continuous.

Base station can configure maximum transmission times K for UE1 and UE2, which can be cell-level, that is, The number of transmissions must not exceed K when all UE exempt from authorized transmissions in cell corresponding to the base station；The maximum transmitted time Number is also possible to group's grade, that is, shares identical one group of UE for exempting from authorized transmissions resource and exempt from transmission time when authorized transmissions Number must not exceed K；The maximum transmission times can also be with user class, that is, base station is that different UE configures different maximum biographies Defeated number.It should be noted that above-mentioned K is not intended to limit the actual transmissions number that UE exempt from authorized transmissions, UE can be from default Numerical value set in select numerical value no more than K as the actual transmissions number for exempting from authorized transmissions.

The method for exempting from the number of transmissions of authorized transmissions, terminal device are determined according to channel quality described above is terminal device The number of transmissions for exempting from authorized transmissions can also be determined according to the type of service of transmission block to be transmitted.

For example, preset set of values is combined into { 1,2,3,4 }, the maximum transmission times of network equipments configuration are 3, work as transmission block Corresponding type of service is that highly reliable low time delay communicates (ultra-reliable and low latency Communications, URLLC) business when, terminal device can be passed according to the maximum of numerical value set and network equipments configuration Defeated number determines that the actual transmissions number for exempting from authorized transmissions is 3, that is, before meeting the maximum transmission times of network equipments configuration It puts and selects maximum numerical value from numerical value set, to guarantee transmission reliability；When the corresponding type of service of transmission block is mMTC When business, terminal device can exempt from authorized transmissions according to the determination of the maximum transmission times of numerical value set and network equipments configuration Actual transmissions number is 2.

The embodiment for exempting from the number of transmissions of authorized transmissions, terminal device are determined according to single-factor described above is terminal device The number of transmissions for exempting from authorized transmissions can also be determined according to multiple-factor, that is, the network equipment can be according to channel quality and transmission block Corresponding type of service determines the number of transmissions for exempting from authorized transmissions.

For example, preset set of values is combined into { 1,2,3,4 }, the maximum transmission times of network equipments configuration are 4, work as transmission block Corresponding type of service be mMTC business when, if the value of current SNR fall in section (a, b) shown in Fig. 3 it is interior when, terminal device can To select 3 from above-mentioned numerical value set as the number of transmissions for exempting from authorized transmissions, if the value of current SNR falls in area shown in Fig. 3 Between (c, d) it is interior when, terminal device can be selected from above-mentioned numerical value set 2 as the number of transmissions for exempting from authorized transmissions；Work as transmission The corresponding type of service of block be URLLC business when, if the value of current SNR fall in section (a, b) shown in Fig. 3 it is interior when, terminal is set It is standby to be selected from above-mentioned numerical value set 4 as the number of transmissions for exempting from authorized transmissions, if the value of current SNR fall it is shown in Fig. 3 Section (c, d) it is interior when, terminal device can be selected from above-mentioned numerical value set 3 as the number of transmissions for exempting from authorized transmissions.

It should be noted that the channel quality of above-described embodiment description and/or the type of service of transmission block pass corresponding with N System can be direct corresponding relationship, be also possible to indirect corresponding relationship, and direct corresponding relationship is referred to without by removing Information except the type of service of channel quality and/or transmission block determines that N, indirect corresponding relationship are referred to first according to channel Quality and/or the type of service of transmission block determine average information, then determine N according to the average information, which can be with It is one, is also possible to multiple, the application does not limit this.

It should be understood that in this application, " when ... " refer to that terminal device or the network equipment can be done under certain objective circumstances Corresponding processing out, is not limiting time, does not also require terminal device or the network equipment certain when realizing corresponding function There is the movement of judgement, does not also mean that there are other restrictions.

Optionally, above-mentioned reference information includes MCS.

Different MCS can correspond to different the number of transmissions, and MCS and channel quality are of equal value to a certain extent.This In MCS refer to most suitable MCS under current channel conditions.Channel quality is better, and corresponding MCS is higher；Channel quality is poorer, Corresponding MCS is lower.Higher MCS means higher transmission rates.When channel quality is characterized with SNR, MCS is often and SNR With corresponding relationship.Therefore, it determines that target exempts from authorized transmissions resource according to channel quality, also can be described as determining mesh according to MCS Mark exempts from authorized transmissions resource.

Fig. 5 shows the schematic diagram of MCS provided by the present application with the corresponding relationship for the number of transmissions for exempting from authorized transmissions.Fig. 5 In, abscissa indicates the call number of MCS, and ordinate indicates the value of N, when terminal device is adjusted using the MCS that call number is a When system coding, terminal device can determine that the number of transmissions for exempting from authorized transmissions is 4, when terminal device is the MCS of d using call number When being modulated coding, terminal device can determine that the number of transmissions for exempting from authorized transmissions is 1.

Fig. 5 is merely illustrative of, the application to the concrete form of the corresponding relationship of MCS and the number of transmissions without limitation, MCS It can also be indicated by table with the corresponding relationship of the number of transmissions.

The corresponding relationship of MCS and the number of transmissions can be one-to-one, is also possible to one-to-many, can also be many-one, That is a MCS can correspond to a value in preset numerical value set, a MCS can also correspond to preset set of values Multiple values in conjunction, multiple MCS can also correspond to a value in preset numerical value set, when a MCS corresponds to preset number When multiple values in value set, terminal device can select a value according to other parameters or condition from multiple value, this Application does not limit this.

The network equipment can count the MCS, the number of transmissions and transmission reliability of multi-time no authorized transmissions, and be tied according to statistics Fruit determines the corresponding relationship between MCS, the number of transmissions and transmission reliability, and corresponding relationship is allocated to terminal device, in order to Requirement and currently used MCS of the terminal device according to transmission block to transmission reliability select the number of transmissions.Certainly, above-mentioned right Should be related to can also be configured in terminal device by human configuration mode, and how the application obtains reference information to terminal device Without limitation.

Optionally, terminal device according to MCS from numerical value set determine N before, method 200 further include:

S203, terminal device are exempted from authorized transmissions from least two according to the type of service of channel quality and/or transmission block and are provided Determine that target exempts from authorized transmissions resource in source, which exempts from authorization resources and be used for transmission transmission block.

S204, terminal device exempt from authorized transmissions resource according to the target and determine MCS, the target exempt from authorized transmissions resource with There are preset corresponding relationships by MCS.

MCS can also be bound together while binding with the number of transmissions with authorized transmissions resource is exempted from, that is, terminal device choosing When selecting use and exempting from authorized transmissions resource A and send upstream data, also determine that sending the MCS that uses of upstream data is to exempt from authorization to pass The MCS of defeated resource A binding, while also determining the number of transmissions for exempting from authorized transmissions.Terminal device can be according to channel quality And/or the type of service of transmission block from it is multiple exempt from authorized transmissions resource select one exempt from authorized transmissions resource.

For example, when channel quality is preferable, terminal device can choose that transmission rate is higher to exempt from authorized transmissions resource, when When channel quality is poor, terminal device can choose transmission, and transmission rate is lower exempts from authorized transmissions resource.

In another example when the corresponding type of service of transmission block is the type of service more demanding to transmission reliability, terminal Equipment can choose that transmission rate is lower to exempt from authorized transmissions resource, when the corresponding type of service of transmission block is to transmission reliability It is required that when lower type of service, terminal device can choose that transmission rate is higher to exempt from authorized transmissions resource.

For another example when channel quality is preferable, and when the corresponding type of service of transmission block be transmission reliability is required compared with When low type of service, terminal device, which can choose, exempts from authorized transmissions resource A, when channel quality is bad, and works as transmission block pair When the type of service answered is the type of service more demanding to transmission reliability, terminal device, which can choose, exempts from authorized transmissions resource B, wherein the transmission rate for exempting from authorized transmissions resource A is greater than the transmission rate for exempting from authorized transmissions resource B.

It should be strongly noted that MCS and channel quality are of equal value to a certain extent.Here MCS refers to currently Most suitable MCS under channel situation.Channel quality is better, and corresponding MCS is higher；Channel quality is poorer, and corresponding MCS is lower. Higher MCS means higher transmission rates.When channel quality is characterized with SNR, MCS often has corresponding relationship with SNR.Cause This, determines that target exempts from authorized transmissions resource according to channel quality, also can be described as determining that target exempts from authorized transmissions money according to MCS Source.

Terminal device has determined exempt from authorized transmissions resource after, that is, can determine this exempt from authorized transmissions resource binding MCS, need Illustrate, the corresponding relationship of the MCS and N of above-described embodiment description can be direct corresponding relationship, be also possible to indirectly Corresponding relationship, direct corresponding relationship refer to being not necessarily to determine N by the information in addition to MCS, what indirect corresponding relationship referred to It is that average information is determined according to MCS first, N is then determined according to the average information, which can be one, can also be with Be it is multiple, the application does not limit this.For example, one is exempted from authorized transmissions resource and can also bind multiple MCS, terminal device can To select suitable MCS according to other parameters or condition, the application is not construed as limiting this.

Terminal device can determine the number of transmissions for exempting from authorized transmissions after MCS has been determined, so as to according to practical feelings The suitable the number of transmissions of condition (for example, type of service of channel quality and/or transmission block) flexible choice is guaranteeing transmission reliability While improve resource utilization.

One is enumerated again below according to MCS and exempts from the example that authorized transmissions resource determines N.

Base station is that UE configures at least one triple, that is, (resource, MCS, N), wherein resource refers to that exempting from authorization for one passes The time-frequency resource allocating or resource index of defeated resource.Each triple represents one and exempts from authorized transmissions resource and exempt to authorize with this The MCS and N of transfer resource binding.

Base station can be current based on UE channel situation, configure at least one for UE and exempt from authorized transmissions resource and each exempt from Authorized transmissions resource corresponding MCS and K.Then, UE can exempt to authorize according to actual channel conditions at least one that base station configures One is selected in transfer resource to be transmitted, and exempts from authorized transmissions resource corresponding MCS and K using with this when transmission.For example, base station According to channel measurement, it is believed that the MCS of current most suitable UE is MCS3, therefore for the UE MCS for being configured with binding be respectively MCS2, Three of MCS3 and MCS4 exempt from authorized transmissions resource, as shown in fig. 6, each exempting from authorized transmissions resource binds different N.Then, should Can be configured according to actual channel conditions at that time in base station when transmitting data three of UE exempt to select to close in authorized transmissions resource Suitable authorized transmissions resource of exempting from is transmitted.For example, channel quality improves, optional as the UE is mobile to center of housing estate direction The transmission of resource 3 is selected, MCS4 and N=3 are used；As the UE is mobile to cell edge, channel quality is deteriorated, and resource 1 may be selected and pass It is defeated, use MCS2 and N=5.After a period of time, the resource of base station configuration may unsuitable UE have been transmitted, at this point, base station can It is reconfigured to authorized transmissions resource is exempted from, as UE, which is reconfigured, new exempts from authorized transmissions resource and corresponding MCS and N.On Stating example and being equivalent to base station is that UE is configured with numerical value set { 3,4,5 }.

Each of above-described embodiment exempt from authorized transmissions resource can be it is continuous or discontinuous.It is so-called to exempt from authorized transmissions Resource be it is discontinuous, refer to that exempting from multiple transmission units included by authorized transmissions resource is not connect in time domain and/or frequency domain Continuous.

Since each authorized transmissions resource of exempting from can be allocated to multiple UE simultaneously, and MCS and N are and exempt to authorize Transfer resource binding, therefore whichever UE exempts from authorized transmissions resource using this, all can only exempt from authorized transmissions money using with this The MCS and N of source binding.In other words, different UE are identical in the same the number of transmissions N exempted from authorized transmissions resource.This has Conducive to the fairness transmitted between UE.There is the present embodiment the reason of beneficial effect to be: if difference UE exempts from authorization biography same The number of transmissions in defeated resource is different, for example, the N=2 of the N=1 of UE1, UE2, then the transmission of obvious UE1 have greater probability with The transmission of UE2 is collided, and causes the transmission reliability ratio UE2 of UE1 low.And difference UE is in the same transmission exempted from authorized transmissions resource Number is identical, then makes the probability for transmitting collision between UE identical, therefore transmission reliability is also identical, ensure that the transmission of different UE Fairness.

Optionally, above-mentioned reference information be transmit transmission block use exempt from authorized transmissions resource.

It is different to exempt from authorized transmissions resource and correspond to different the number of transmissions, for example, under equal conditions, dedicated frequency range High reliablity is in the reliability of common frequency band, and therefore, the corresponding the number of transmissions of dedicated frequency range (for example, frequency range of each operator) can To be a lesser numerical value, to reduce resource usage amount, common frequency band is (for example, authorization frequency spectrum auxiliary intervention (licensed- Assisted access, LAA) unauthorized frequency range in technology) corresponding the number of transmissions can be a biggish numerical value, with Guarantee transmission reliability.In another example when the different frequency range phases for exempting from authorized transmissions resource is simultaneously as different exempts from authorized transmissions Resource is possibly used for transmitting different business, and requirement of the different business to transmission reliability is different, and therefore, different exempts to award The number of transmissions for weighing transfer resource binding may be different, and for one of those exempts from authorized transmissions resource, this is exempted from authorization and passes Defeated resource, which binds a number of transmissions, can make the number of transmissions phase for exempting from all terminal devices of authorized transmissions resource using this Together, guarantee the fairness between terminal device.

It is different to exempt from authorized transmissions resource and correspond to identical the number of transmissions, wherein this is different to exempt from authorized transmissions The resource parameters (for example, subcarrier spacing) of resource may be different, to adapt to the business of different delay requirement.

When terminal device has determined that target exempts from authorized transmissions resource, which exempts from the corresponding transmission time of authorized transmissions resource Number N is the number of transmissions of the terminal device when target exempts from authorized transmissions transmitted over resources.

Optionally, terminal device is according to exempting from of using of transmission transmission block before authorized transmissions resource determines N, and method 200 is also Include:

S205, terminal device are exempted from authorized transmissions from least two according to the type of service of channel quality and/or transmission block and are provided What determining transmission transmission block used in source exempts from authorized transmissions resource (that is, target exempts from authorized transmissions resource), which exempts from authorization and pass There are preset corresponding relationships with channel quality for defeated resource, and/or, which exempts from the business of authorized transmissions resource Yu the transmission block There are preset corresponding relationships for type.

For example, when channel quality is preferable, terminal device can choose that reliability is lower to exempt from authorized transmissions resource, work as letter When road is second-rate, terminal device can choose that reliability is higher to exempt from authorized transmissions resource；In another example when transmission block is corresponding When type of service belongs to high-priority service type, terminal device can choose that reliability is higher to exempt from authorized transmissions resource, when When the corresponding type of service of transmission block belongs to low priority traffice type, terminal device can choose that reliability is lower to be exempted to authorize Transfer resource.Terminal device is also based on channel quality and authorized transmissions resource is exempted from the type of service selection of transmission block, thus Resource utilization can be improved while guaranteeing transmission reliability.

Optionally, before terminal device determines N according to reference information, method 200 further include:

S206, terminal device receive configuration information, and the configuration information is for configuring reference information and the corresponding relationship of N.

The corresponding relationship of reference information and N can be pre-configured in terminal device by configuration information, the corresponding relationship Can be the network equipment statistics different condition under the relationship of communication reliability and the number of transmissions obtain as a result, simultaneously can periodically more New configuration content is guaranteeing the same of transmission reliability so that terminal device, which can choose, suitably exempts from authorized transmissions number Shi Tigao resource utilization.

The network equipment can pass through wireless heterogeneous networks (radio resource control, RRC) signaling, medium access control Make (media access control, MAC) control element (control element, CE) or physical layer signaling (e.g., downlink Control information (downlink control information, DCI)) above-mentioned configuration information is transmitted to terminal device.

The application is equal to the transmitting and receiving mode of the concrete form of configuration information, the name of configuration information and configuration information Without limitation.

After UE has carried out transmitting n times transmission block on exempting from authorized transmissions resource, base station need to transmit this n times and mix Automatic repeat request response is closed, i.e., confirmation/negative (ACK/NACK) message is sent to the UE, to indicate whether base station is properly received The data sent to UE.Base station can use physical hybrid automatic repeat request indicator channel (physical hybrid Automatic repeat request indicator channel, PHICH), class PHICH (PHICH-like), downlink refer to Show the channels such as information (downlink control information, DCI), the public DCI (group common DCI) of group or Information carries ACK/NACK.

Realize the response for exempting from authorized transmissions data to receiving using PHICH loading ACK/NACK with base station below.

1, base station individually responds each transmission in n times transmission.

Each data in N number of data of the same transmission block received are considered as an independent data and rung by base station It answers.This method situation identical suitable for the redundancy versions (redundancy version, RV) of N number of data, because of various RV Others RV does not have independence in addition to RV0 in version, possibly can not individually decode.

It base station can be there are two types of response method.A kind of method is, base station according to n times transmit in the reception feelings transmitted every time Condition independently determines response ACK or NACK.Another method is, as long as the data quilt transmitted at least once in n times transmission Base station is correctly decoded, then base station all responds ACK to all transmission in n times transmission；When transmission all in n times transmission are not correct When decoding, base station all responds NACK to all transmission in n times transmission.

No matter ACK or NACK, be both needed to be carried by PHICH.Base station is individually rung for each transmission in n times transmission It answers, this is required in the different transmission maps to different PHICH in n times transmission.According to the determination side PHICH in Current standards Method, the corresponding PHICH of a upstream data and demodulated reference signal (demodulation reference signal, DMRS) Index and uplink resource allocation index it is related.Based on this rule, in order to which the different transmission maps for transmitting n times arrive On different PHICH, there can be following methods:

Option 1: it is related to this time selected transmission unit of transmission that corresponding PHICH is transmitted every time.

As shown in fig. 7, UE has selected transmission unit 3,8,9,14 to transmit the 4 of same transmission block in exempting from authorized transmissions resource The data of secondary transmission.It is related to the index of transmission unit that corresponding PHICH is transmitted every time, for example, UE is transmitted on transmission unit 3 The corresponding PHICH of data by the transmission unit index (i.e. transmission unit 3) determine.In the n times transmission of same transmission block The indexes that difference transmits corresponding DMRS can be identical, be also possible to different.

Option 2: it is related to DMRS index that corresponding PHICH is transmitted every time.

Standard is predefined or network side has been pre-configured in the n times transmission of same transmission block that homogeneous transmission correspondence is not different The DMRS index of DMRS, n-th transmission are denoted as DMRS (n).In this way, the corresponding PHICH of data that the transmission of UE n-th is sent It is determined by DMRS (n).N times transmit corresponding ascending resource distribution index and can be identical, are such as all made of and exempt from authorized transmissions money The index (transmission unit 4 in such as Fig. 7) of the transmission unit in the lower left corner in source；N times transmit corresponding ascending resource distribution index It can be mutually different, be respectively transmission unit 3,8,9,14 as transmitted corresponding ascending resource distribution in Fig. 7 for 4 times.

2, base station disposably responds all transmission in n times transmission.

Since actually transmit is same transmission block for n times transmission, therefore base station can only send one after receiving n times transmission Secondary response message indicates whether that having had correctly received this n times transmits transmitted information.In other words, n times transmission need to be mapped to On same PHICH.

The case where not bound with transfer resource and/or MCS for N, since the value of N is, base station self-determining by UE It can not determine N, therefore when base station receives a data of UE, it not can determine that the transmission is the data of which time transmission.Due to PHICH determines by DMRS index and the resource allocation of uplink index, therefore in order to realize n times transmission map to same On PHICH, the resource allocation index that this n times transmits corresponding DMRS index and uplink is both needed to identical.Therefore, same UE Fixed DMRS should be bound, if base station is each UE configuration DMRS in advance, then shares the same multiple UE for exempting from authorized transmissions resource Mutually different DMRS should be configured, in order to avoid cause to collide in the transmission map to identical PHICH of difference UE.N times transmission Resource allocation index should also use identical value, such as exempt from the index of the transmission unit in the lower left corner in authorized transmissions resource using use (transmission unit 4 in such as Fig. 7).Certainly, the above method is also applied for the case where N and transfer resource and/or MCS binding.

Particularly, the case where different redundancy versions of same data being transmitted as n times, due to the redundancy in addition to RV0 Version does not have independent decoding capability, therefore the rope of the corresponding transmission unit of first transmission (that is, using transmission of RV0) can be used Attract the corresponding PHICH of calculating.When base station correctly solves data, it is meant that base station necessarily have received using RV0 data (that is, Necessarily know the transmission unit index that first transmission uses), to calculate corresponding PHICH based on this；If base station does not solve correctly Data, then base station does not send PHICH (that is, without response).

The above-detailed method provided by the present application for sending uplink information, in the following, will describe provided by the present application The method for receiving uplink information.

Fig. 8 shows a kind of method for receiving upstream data provided by the present application.This method 800 includes:

S801, the network equipment send configuration information, and for configuring reference information and the corresponding relationship of N, N is the configuration information Terminal device transmits the number of transmission block according to authorized transmissions mode is exempted from, and N is the integer more than or equal to 1, described with reference to letter The corresponding relationship of breath and N determine N corresponding with the reference information according to a reference information for the terminal device.

S802, the network equipment receive N number of upstream data from the terminal device, which includes the transmission block One at the beginning of pass data and N-1 re-transmission data.

The network equipment can be terminal equipment configuration one several value sets, and the numerical value in the numerical value set, which is that N is possible, to be taken Value, when terminal device has transmission block to need to transmit, terminal device can select one according to reference information from numerical value set Numerical value, the numerical value represent the number of transmission, and the number of transmissions may be different under different reference informations, for example, when reference information refers to Show current com-munication environment preferably or current transmission reliability requirement it is not high when, terminal device, which can be reduced, exempts from authorized transmissions The number of transmissions, when reference information instruction current com-munication environment is poor or the reliability requirement of current transmission is higher, terminal is set It is standby to increase the number of transmissions for exempting from authorized transmissions, exempt from authorization biography so as to reduce under the premise of not influencing successful receiving rate The resource of defeated occupancy.

Those skilled in the art can be clearly understood that: the network equipment is equal to the network in method 200 in method 800 Equipment, and the network equipment realizes that the processing mode for the function of receiving N number of upstream data is set with network in method 200 in method 800 The standby processing mode for realizing the function of sending N number of upstream data is corresponding, for sake of simplicity, repeating no more.

The network equipment can exempt from the corresponding maximum transmission times of authorized transmissions resource and guarantee to exempt to award using this by configuring The fairness transmitted between each terminal device of transfer resource is weighed, for example, not having emergency data usually in mMTC scene Presence, it is mandatory parameters that K, which can be set, in the network equipment, that is, terminal device must be complied with the constraint of K, thereby may be ensured that each The fairness transmitted between a terminal device.

The network equipment can also to use it is different exempt from communication that authorized transmissions resource exempt from the scene of authorized transmissions can Relationship between property and the number of transmissions is counted, and is determined under the premise of meeting communication reliability requirement according to statistical result Exempt from the corresponding the number of transmissions of authorized transmissions resource, and the corresponding relationship for exempting from authorized transmissions resource and the number of transmissions is passed through with confidence Breath informs terminal device, and terminal device is allow suitably to exempt from authorized transmissions resource according to authorized transmissions resource selection is exempted from, thus Resource utilization can be improved while guaranteeing transmission reliability.

The network equipment can also different MCS exempt from the communication reliability in the scene of authorized transmissions and transmission is secondary to using Relationship between number is counted, and determines the corresponding biography of MCS under the premise of meeting communication reliability requirement according to statistical result Defeated number, and by the corresponding relationship of MCS and the number of transmissions by configuration information inform terminal device, allow terminal device according to MCS selection suitably exempts from authorized transmissions resource, so as to improve resource utilization while guaranteeing transmission reliability.

Optionally, target exempts from authorized transmissions resource and the corresponding relationship of N, comprising: target exempts from authorized transmissions resource and MCS The corresponding relationship of corresponding relationship and MCS and N.

The embodiment of the present application one: the maximum value of base station configuration the number of transmissions

Base station can exempt from the number of transmissions maximum value K of authorized transmissions for UE configuration.It is that UE is configured with Ω that this, which is equivalent to base station, The number of transmissions of={ 1,2,3 ..., K } can use value set, determine the biography of current transmission when UE is transmitted in Ω according to the actual situation Defeated number K0, K0 ∈ Ω.

If UE determines that K0, the SNR that can be equivalent to UE based on channel determine K0 based on channel quality in Ω.SNR is bigger, Channel quality is better, and K0 is smaller；SNR is smaller, and channel quality is poorer, and K0 is bigger.Figure 16 be determined based on SNR one of K0 it is specific Example, certainly, Figure 16 can also be presented as form.UE measures channel first, obtains SNR, is then based on Figure 16 and is corresponded to K0 value.

Figure 17 is a specific example, it is assumed that the number of transmissions maximum value of base station configuration is K=4.UE1 apart from base station compared with Closely, channel quality is preferable, and UE1 is K0=2 based on the number of transmissions that Figure 17 is determined；UE2 apart from base station farther out, channel quality compared with Difference, UE2 are K0=4 based on the number of transmissions that Figure 17 is determined.It should be strongly noted that in Fig. 5 exempt from authorized transmissions resource can To be continuous or discontinuous.

In the present embodiment, base station is that UE configures maximum transmission times K, and it is specific to can be cell, i.e., all UE in cell It carries out exempting to be based on same Ω progress K0 selection when authorized transmissions；K is also possible to based on one group of UE, such as base station is shared Same one group of UE for exempting from authorization resources configures identical K；K can also be every user's, i.e., base station can be for different UE configuration not Same K.Nevertheless, base station does not indicate that the number of transmissions K0 actually used in UE transmission, and only indicates the maximum of K0 and permit Perhaps it is worth.The value of K0 is taken within the scope of 1~K fixed by UE.

The embodiment of the present application two: exempting from authorization resources or MCS is associated with K

The present embodiment proposes, can will exempt from authorization resources and associate with K, i.e., each exempts from authorization resources and bind one (MCS, K) or K.When UE selects some to exempt from authorization resources transmission, it is necessary to using (MCS, the K) or K bound with the resource.

The binding for exempting from authorization resources and K can be realized there are many mode.

One kind being achieved in that base station is that UE configures at least one (resource, MCS, K) or (resource, K) tuple, wherein money Source refers to the time-frequency resource allocating or resource index for exempting from authorization resources.Each tuple represent one exempt from authorization resources and with (MCS, the K) or K of resource binding.In other words, each exempt from authorization resources and bind a K, i.e., any UE selects this to exempt to authorize The number of transmissions when resource transmission is all identical, and is equal to the K for exempting from authorization resources binding with this.

Another kind is achieved in that standard predefines or network is pre-configured the mapping relations of MCS and K, as shown in figure 18, when So, Figure 18 can also be presented as form.On this basis, base station is that UE configures at least one (resource, MCS), and UE is according to figure Mapping relations shown in 18 can be determined corresponding K by MCS.

In a specific embodiment, base station can be configured at least one for UE and be exempted to award based on the current channel conditions of UE It weighs resource and each exempts from authorization resources corresponding MCS and K.Then, UE can be configured extremely according to actual channel conditions in base station Exempt to select one in authorization resources for few one to be transmitted, exempts from authorization resources corresponding MCS and K using with this when transmission.For example, Base station is according to channel measurement, it is believed that currently most suitable MCS is MCS3 to certain UE, therefore is configured with binding MCS for the UE and is respectively Three of MCS2, MCS3, MCS4 exempt from authorization resources, as shown in figure 19, each exempt from authorization resources and bind different K.Then, which exists Suitable resource can be selected to be passed in three resources that base station configures according to actual channel conditions at that time when transmitting data It is defeated.For example, channel quality improves as the UE is mobile to center of housing estate direction, resource 3 may be selected and transmit, use MCS4 and K= 3；As the UE is mobile to cell edge, channel quality is deteriorated, and resource 1 may be selected and transmit, use MCS2 and K=5.For a period of time Later, the resource of base station configuration may unsuitable UE have been transmitted, at this point, base station can be reconfigured to authorization resources are exempted from, i.e., It is reconfigured for UE and new exempts from authorization resources and corresponding MCS and K.Above-mentioned example be equivalent to base station be UE be configured with Ω=3, 4,5}.Resource in embodiment described in Figure 19 can also only bind K without binding MCS.

Each of the present embodiment exempt from authorized transmissions resource can be it is continuous or discontinuous.It is so-called to exempt from authorized transmissions money Source be it is discontinuous, refer to that exempting from multiple transmission units included by authorized transmissions resource is discontinuous in time domain and/or frequency domain 's.

Since each authorized transmissions resource of exempting from can be allocated to multiple UE simultaneously, and MCS and K are and exempt to authorize Transfer resource binding, therefore whichever UE exempts from authorized transmissions resource using this, all can only exempt from authorized transmissions money using with this The MCS and/or K of source binding.In other words, different UE are identical in the same the number of transmissions K exempted from authorized transmissions resource.This Be conducive to the fairness transmitted between UE.If difference UE is different in the same the number of transmissions exempted from authorized transmissions resource, for example, The K=2 of the K=1 of UE1, UE2, then the transmission of obvious UE1 has the transmission of greater probability and UE2 collision, causes the transmission of UE1 can It is low by property ratio UE2.And the same the number of transmissions exempted from authorized transmissions resource of difference UE is identical, then makes transmission collision between UE Probability is suitable, therefore transmission reliability is also suitable, therefore ensure that the fairness of different UE transmission.

The embodiment of the present application three: base station in response HARQ-ACK

After UE has carried out K transmission of some data on exempting from authorization resources, base station need to carry out this K times transmission HARQ-ACK response, i.e. transmission ACK/NACK, indicate whether base station has correctly received the data of UE.Base station may using PHICH, PHICH-like (class PHICH), DCI, group common DCI (organizing public DCI) etc. exempt from the response letter of authorization data to carry Breath.

Present embodiment assumes that base station carries the response message for exempting from authorization data, realization pair using traditional PHICH channel The response of K transmission of some data.But in specific response, there can be different concrete forms.The present embodiment can be with embodiment One is used in combination, and can also be used in combination with embodiment two.

1) base station individually responds each transmission in K transmission

I.e. each transmission in K transmission of the UE same data sent is considered as an independent data and rung by base station It answers.The case where that this method is suitable for K transmission is repeated version (the i.e. identical RV) of same data, because transmission version is (no Same RV) in the case of redundancy versions in addition to RV0 do not have independence, possibly can not individually decode.

It base station can be there are two types of specific response method.A kind of method is that base station connects according to each transmission in K transmission It receives situation and independently determines response ACK or NACK.Another method is, as long as at least one transmission is by base in K transmission Station is correctly decoded, then base station all responds ACK to all transmission in K transmission；When the incorrect solution of transmission all in K transmission When code, base station all responds NACK to all transmission in K transmission.

No matter ACK or NACK, be both needed to be carried by PHICH.Base station is individually rung for each transmission in K transmission It answers, this requires the different transmission in K transmission that should be mapped in different PHICH resources.According to the PHICH money in Current standards Source determines method, the corresponding PHICH and n of a UL data_DMRSAnd the resource allocation index of UL transmission is related.Based on this rule Then, in order to make K times transmission in different transmission maps to different PHICH resources on, can have following methods:

A) option 1: it is related with selected transmission unit is transmitted that corresponding PHICH resource is transmitted every time.

As shown in figure 20, certain UE has selected the K=4 of the same data of the transmission of transmission unit 3,8,9,14 in exempting from authorization resources Secondary transmission.Transmitting corresponding PHICH resource every time should be related with the index of transmission unit, for example, UE is transmitted on transmission unit 3 Data PHICH resource by the transmission unit index (i.e. transmission unit 3) determine.In K transmission of same data not The corresponding n with transmission_DMRSIt can be identical, or be different.

B) option 2: corresponding PHICH resource and n are transmitted every time_DMRSIt is related

Tentative standard is predefined or network side has been pre-configured the different transmission in K transmission of same data and has corresponded to difference n_DMRS, the n of kth time transmission_DMRSIt is denoted as n_DMRS(k).In this way, the corresponding PHICH resource of UE kth time transmission can be by n_DMRS(k) certainly It is fixed.K transmission corresponding UL resource allocation index can be identical, such as be all made of the transmission list for exempting from the lower left corner in authorization resources The index (transmission unit 4 in such as Figure 20) of member；K transmission corresponding UL resource allocation index can be it is mutually different, such as The corresponding UL resource allocation of K=4 transmission is respectively transmission unit 3,8,9,14 in Figure 20.

2) base station disposably responds all transmission in K transmission

It is same data due to transmitting actually transmit for K times, therefore base station can only be sent once after receiving K transmission Response, indicates whether to have had correctly received this K times data to be transmitted.In other words, K transmission need to be mapped to same In PHICH resource.

For embodiment one, due to the value of actual transmissions number K0 be it is self-determining by UE, base station is in advance simultaneously Do not know, therefore when base station receives a transmission of UE, not can determine that the transmission be in K0 transmission that UE is sent which is secondary. Since PHICH resource is by n_DMRSAnd the resource allocation of UL transmission is indexed and is determined, therefore in order to realize K transmission map to same In PHICH resource, the corresponding n of this K times transmission_DMRSAnd UL transmission resource allocation index be both needed to it is identical.Therefore, same UE is answered Bind fixed n_DMRS, if base station is each UE configuration n in advance_DMRS.Sharing the same multiple UE for exempting from authorization resources should configure mutually not Identical n_DMRS, in order to avoid cause to collide in the transmission map to identical PHICH resource of difference UE.The resource of K transmission Distribution index should also use identical value, such as exempt from the index of the transmission unit in the lower left corner in authorization resources (in such as Figure 20 using use Transmission unit 4).Certainly, the above method is also applied for embodiment two.

Particularly, the case where being transmitted as the different redundancy versions of same data for K times, due to the redundancy in addition to RV0 Version does not have independent decoding capability, therefore can be used the first time in K transmission and transmit (i.e. RV0) corresponding transmission unit Index is to calculate corresponding PHICH.When base station has correctly solved data, it is meant that base station necessarily has received RV0 and (necessarily knows The transmission unit of RV0 indexes), to calculate corresponding PHICH resource based on this；If base station has not solved data, base station correctly PHICH is not sent (i.e. without response).
