It is the structural representation of a kind of data transmission system that the embodiment of the present invention provides referring first to Fig. 1, Fig. 1, by Fig. 1 Shown in, this data transmission system includes base station 110 and terminal 120, can set up data communication between base station 110 and terminal 120 Connecting, it is achieved data are transmitted, in current LTE system, transmitting uplink data is up by transmit on down control channel Scheduling grant information is controlled.I.e. base station 110 sends uplink scheduling allowance on the down control channel of certain descending sub frame Information, terminal 120 carries out upstream data transmission on certain follow-up sub-frame of uplink afterwards.It should be noted that described above is only Being exemplary, the present invention program is not limited to LTE system.Other system, channel radio such as of future generation can also be applied to Communication system.

For introducing the more frequency spectrum resource performance index requirements with satisfied constantly lifting, open from 3GPP Release 13 Begin, introduce LAA (Licensed-Assisted Access to Unlicensed Spectrum) system, it is achieved that awarding The auxiliary of power frequency spectrum (such as: the frequency spectrum of LTE system) is lower uses unauthorized frequency spectrum resource (such as the frequency spectrum of 5GHz).In LAA system In system, owing to introducing unlicensed spectrum resource, therefore LAA system need to follow unlicensed spectrum on the basis of LTE system Some mechanism.Various countries are specified respectively for the use of unlicensed spectrum at present, and some of them countries and regions define Needing to use LBT (listen before talk) mechanism in unauthorized frequency range, i.e. listem-before-talk mechanism, is carrying out data transmission Before, the state first monitor channel is the most idle, if channel idle, carries out data message and the transmission of the information of control, no It is not transmitted.This can cause transmitting whether have certain uncertainty, and this makes in LAA system actual upper and lower The ascending-descending subframes distribution that row subframe distribution is different from LTE system, i.e. in LAA system, the distributing position of ascending-descending subframes is no longer Fixing.

The process of channel-monitoring is also referred to as clear channel assessment (CCA) (ClearChannelAssessment, referred to as CCA). Exemplary, it is assumed that the power of base station measurement to channel is not less than-62dBm, then this website thinks that channel is busy；Low Think that channel is idle in-62dBm then this website.

As a kind of exemplary mode that the state of monitor channel is the most idle, concrete, whether UE detection around has Miscellaneous equipment just sends data in destination channel.If this target channel is taken by miscellaneous equipment, can monitor at next Continue when cycle arrives to monitor, it is also possible to no longer monitor according to instruction；If it is idle to listen to channel resource, this UE can account for immediately Use this destination channel.Channel holding time is a fixed value, and this fixed value is the sub-frame of uplink of SRS configuration information configuration The time span of last symbol, it is contemplated that UE is reported to the transformation process of Channel Detection at SRS, can examine at subsequent channels Location sets a silence period before putting.Preferably, if it is idle to listen to channel resource, a random number L conduct can be generated Back off time, in this back off time, continues to monitor destination channel, if detecting, L destination channel is in idle condition, then Back off time terminates, and this UE just can take this destination channel and carries out SRS and report simultaneously.If UE detects that channel status is non- Idle (the most being taken by other UE), then within this cycle equipment can not busy channel, then this UE can wait until the next one Detection is continued in the fixed position in cycle.

As the mode that the another kind that the state of monitor channel is the most idle is exemplary, concrete, when UE needs to report SRS When, trigger initial detecting.If UE initial detecting is in idle condition to destination channel, this destination channel can be taken, and It is pre-configured with a Channel holding time T by base station；If UE initial detecting is busy to destination channel state, then can generate one (defer period) time in individual postponement cycle, if still detecting that destination channel is done cycle time postponing, then continue raw One is become to postpone cycle time.UE can take destination channel after L detection time detecting is the free time to channel status, accounts for It is T with the destination channel time.

Have already mentioned above, LAA system led in/out a lot of new challenge.Further for example, depositing due to LBT process , the transmission of upstream data to be carried out, at least successfully to carry out twice LBT process.It is successfully to carry out descending LBT mistake for the first time Journey so that base station can issue the control information of uplink scheduling, another time is successfully to carry out up LBT process so that UE is permissible Upload upstream data.Owing to twice LBT process not necessarily can meet simultaneously, and likely it is separated by relatively long a period of time. It is therefore desirable to avoid dispatching failure scenarios because of LBT failure as far as possible, further need exist for improving further dispatching efficiency.

It should be noted that terminal the most described can be suitable for multiple carrier wave and a base station communicates, also Can communicate over a number of carriers with multiple base stations simultaneously.In above-mentioned multiple carrier waves, one of them carrier wave can be by really Being set to is main carrier (PCC), and main carrier can apply to the main plot (PCell) at terminal place, and main plot can lead to terminal Cross the configuration that high-level signaling (such as RRC) is semi-static.In addition to main carrier, other carrier waves can be auxiliary carrier wave (SCC), auxiliary carrier wave The secondary cell at terminal place can be applied to.Exemplary, main carrier can use the first frequency spectrum to configure, the first frequency Spectrum can be to authorize frequency spectrum or unlicensed spectrum, and accordingly, auxiliary carrier wave can use the second frequency spectrum to configure, the second frequency Spectrum can be unlicensed spectrum or authorize frequency spectrum.Described first frequency spectrum and the second frequency spectrum are configurable to the frequency spectrum differed.

The transmission of the uplink scheduling Grant information that transmitting uplink data involved by the embodiment of the present invention is corresponding is divided into two In the stage, first stage uplink scheduling Grant information is public, a semi-static Grant information, it may include Resource Block (Resource Block is called for short RB) distribution information, MCS class information etc.；Second stage is that a concrete upstream data passes Defeated schedule information, can trigger PUSCH channel and be transmitted in certain subframe, but the of current uplink scheduling Grant information Two-stage do not comprises MCS grade, thus multiple sub-frame of uplink being scheduled all distributes identical MCS grade, and many height The channel quality of the terminal 120 on frame may be different, it is thus possible to occur the son that the MCS grade of distribution sends with concrete PUSCH The unmatched situation of channel quality of frame.Specifically, if the MCS grade of distribution is too high, PUSCH data can be caused to send The bit error rate raises, and reduces systematic function, if the MCS grade of distribution is too low, may reduce the service efficiency of system resource.

The control Information Design Methods of the embodiment of the present invention is by being carried out based on the basis of above-mentioned uplink scheduling Grant information Improvement.

Seeing Fig. 2, Fig. 2 is that the embodiment of the present invention provides a kind of schematic flow diagram controlling Information Design Methods, such as Fig. 2 institute Showing, the method can comprise the following steps that

S201, base station determine at least one sub-frame of uplink that terminal is transmitted.

In embodiments of the present invention, terminal, when PUSCH sends subframe, for different sub-frame transmission, is required to by base The uplink scheduling Grant information that distribution of standing is different, so base station is firstly the need of determining that terminal carries out the subframe of uplink, then Again uplink scheduling Grant information is designed.

S202, base station generate the uplink scheduling Grant information corresponding with at least one sub-frame of uplink being scheduled, described on Row scheduling grant information includes MCS class information, and this MCS class information includes MCS reference grade and MCS side-play amount.

Wherein, MCS class information refer to the modulation that used during the sub-frame transmission data corresponding with this MCS class information with Coding strategy grade.

In embodiments of the present invention, due to this uplink scheduling Grant information be for the data of sub-frame of uplink transmission carry out The schedule information controlled, so the MCS class information comprised in this uplink scheduling Grant information also refers in terminal transmission The modulation used during row sub-frame data and coding strategy grade.This MCS class information is inclined by MCS reference grade and MCS Shifting amount is determined jointly.

In embodiments of the present invention, described MCS reference grade is that public MCS controls information, and described MCS side-play amount is described The side-play amount of the MCS the most described grade MCS reference grade that sub-frame of uplink is used.

Wherein, MCS reference grade is public, semi-static MCS class information, is equivalent to multiple sub-frame of uplink and all uses Same MCS reference grade, and MCS side-play amount is the MCS side-play amount corresponding with this sub-frame of uplink, thus this sub-frame of uplink is made MCS grade jointly can be determined by MCS reference grade and MCS side-play amount.

Alternatively, in some possible embodiments of the present invention, described uplink scheduling Grant information is divided into the first rank Section uplink scheduling Grant information and second stage uplink scheduling Grant information, described MCS reference grade is positioned at described first rank Section uplink scheduling Grant information, described MCS offset bit is in described second stage uplink scheduling Grant information.

Alternatively, in other possible embodiments of the present invention, this MCS class information can also use other side Formula is included in uplink scheduling Grant information.

Alternatively, in one embodiment of the invention, described MCS reference grade information is positioned at mandate auxiliary access The MCS instruction of first stage uplink scheduling Grant information described in (Licensed Assisted Access is called for short LAA) system In territory.

Further, alternatively, described MCS offset bit is in the shortening of described second stage uplink scheduling Grant information In MCS instructions field, the bit length of described shortening MCS instructions field is less than the bit length of MCS instructions field.

It is to be appreciated that in embodiments of the present invention, for determining the MCS side-play amount of MCS grade that sub-frame of uplink used Can be based on a skew in MCS reference grade, so MCS side-play amount can be understood as one to MCS reference grade Adjustment amount, it is preferred that the level value of MCS side-play amount less than the level value of MCS reference grade, thus can be able to design the For indicating the bit length of the shortening MCS instructions field of this MCS side-play amount less than being somebody's turn to do in two-stage uplink scheduling Grant information The bit length of MCS reference grade.Such as, MCS reference grade can be tens grades to twenties grades, and MCS side-play amount can With only for what.This kind of adjustment mode is proved to be useful, and MCS side-play amount can change dynamically, can be by transient channel Quality obtains, and has the most effectively reacted the change of momentary channel quality.It addition, the value of MCS reference grade can also be based on week Phase property or based on event whole updating.

Alternatively, in some possible embodiments of the present invention, may carry out due to system is up many subframes Scheduling, i.e. base station use a multiple sub-frame of uplink in descending sub frame dispatch terminal side, a descending sub frame scheduling the most here Terminal carries out the subframe of uplink may be for multiple, namely uplink scheduling Grant information is for is multiple up sons Frame sends, and now first stage uplink scheduling Grant information will send for the plurality of sub-frame of uplink, and on this first stage Row scheduling grant information, by corresponding multiple second stage uplink scheduling Grant information, corresponds respectively to multiple sub-frame of uplink, specifically Ground, the plurality of sub-frame of uplink is positioned at by using simultaneously in the MCS reference grade of first stage uplink scheduling Grant information, re-uses position MCS side-play amount the most corresponding with each sub-frame of uplink in second stage uplink scheduling Grant information calculates on variant jointly The MCS grade of row subframe.

Specifically, this first stage uplink scheduling Grant information can be cell level uplink scheduling Grant information, and the Two-stage uplink scheduling Grant information can be user class uplink scheduling Grant information.

Specifically, as an example of the present invention, if 2 sub-frame of uplink of terminal scheduling, the two sub-frame of uplink all makes With same first stage uplink scheduling Grant information, in this first stage uplink scheduling Grant information, comprise a benchmark MCS class information, such as can use LTE system original MCS instructions field, use 5 bit to represent MCS reference grade information, As MCS reference grade may be configured as 10.

For these 2 sub-frame of uplink, by corresponding for difference two second stage uplink scheduling Grant information, in second stage In uplink scheduling Grant information, a MCS offset field is set, represents the MCS grade phase that actual each sub-frame of uplink uses Side-play amount for benchmark MCS grade.For example, the field of two bit can be used to represent this side-play amount.Thus can pass through This MCS reference grade and this side-play amount determine the MCS grade that each sub-frame of uplink is used jointly.

Alternatively, MCS reference grade can not also use LTE system original MCS instructions field, and additionally designs a word Section is for arranging MCS reference grade.

Alternatively, in other possible embodiments of the present invention, it is also possible to simultaneously at first stage uplink scheduling Grant information arranges MCS reference grade and MCS side-play amount, or arranges in second stage uplink scheduling Grant information simultaneously MCS reference grade and MCS side-play amount, finally determine each up son jointly also with this MCS reference grade and MCS side-play amount The MCS grade that frame is used.

Uplink scheduling Grant information is sent to described terminal by S203, base station.

In embodiments of the present invention, uplink scheduling Grant information is sent to terminal by base station, so that described terminal is according to institute State MCS reference grade and described MCS side-play amount obtains being used when described terminal sends described sub-frame of uplink on PUSCH MCS grade.

Be appreciated that due to this MCS class information be base station on PUSCH, send sub-frame of uplink data by terminal time divided The MCS grade joined, so base station needs to be sent to terminal this class information by uplink scheduling Grant information, then terminal will Receive the uplink scheduling Grant information that base station sends.

Specifically, terminal, in sending uplink scheduling Grant information, passes sequentially through physical downlink control channel PDCCH and sends The first stage uplink scheduling Grant information of uplink scheduling Grant information and first stage uplink scheduling Grant information, such as, First moment sent first stage uplink scheduling Grant information, then sent at once in second stage in ensuing second moment Row scheduling grant information.

Specifically, terminal is when sending uplink scheduling Grant information, it would however also be possible to employ other sequential passes sequentially through thing Reason down control channel PDCCH sends first stage uplink scheduling Grant information and second stage uplink scheduling Grant information.

Specifically, described first stage uplink scheduling Grant information is sent to described terminal by the first frequency spectrum, and described the Two-stage uplink scheduling Grant information is sent to described terminal, wherein, described first frequency spectrum and described second by the second frequency spectrum Frequency spectrum is different.

Wherein, this first frequency spectrum can be to authorize frequency spectrum or unlicensed spectrum, and this second frequency spectrum can be unlicensed spectrum Or mandate frequency spectrum, such as, when the first frequency spectrum is for authorizing frequency spectrum, this second frequency spectrum is unlicensed spectrum, when the second frequency spectrum is non- When authorizing frequency spectrum, this first frequency spectrum is for authorizing frequency spectrum.

S204, terminal obtain terminal according to MCS reference grade and MCS side-play amount and send at least one on PUSCH The MCS grade used during row subframe.

Alternatively, in some possible embodiments of the present invention, described terminal according to described MCS reference grade and Described MCS side-play amount obtains the MCS grade used when described terminal sends at least one sub-frame of uplink described on PUSCH, Including:

Described terminal determines the MCS etc. that described terminal is used when sending at least one sub-frame of uplink described on PUSCH Level is MCS grade obtained after MCS side-play amount described in described MCS reference grade superposition.

Alternatively, in some possible embodiments of the present invention, described terminal according to described MCS reference grade and Described MCS side-play amount obtains the MCS grade used when described terminal sends at least one sub-frame of uplink on PUSCH, also wraps Include:

Described terminal according to listem-before-talk LBT detection the frequency of failure determine terminal sends on PUSCH described at least one The MCS grade used during sub-frame of uplink be after MCS side-play amount described in MCS reference grade superposition obtained by MCS grade, or MCS reference grade.

Specifically, when described terminal sends sub-frame of uplink at up PUSCH, if detecting, the LBT detection frequency of failure is little When equal to n times, described terminal determines that the MCS grade that described terminal is used when sending sub-frame of uplink on PUSCH is described MCS grade obtained by after MCS side-play amount described in MCS reference grade superposition, wherein, N is a configurable parameter, value model Enclosing can be positive integer；

When the LBT detection frequency of failure being detected more than n times, on described terminal determines that described terminal sends on PUSCH The MCS grade used during row subframe is described MCS reference grade.

It should be strongly noted that benchmark MCS grade can be semi-static, i.e. by a longer statistical average letter The MCS grade that road quality obtains, and MCS side-play amount can be dynamic, momentary channel quality obtain.If user LBT loses Lose number of times and reach preset value (such as: this preset value is bigger), then user carries out when up PUSCH data send and MCS side-play amount The transmission time interval of control information is the most long, then the MCS grade obtained by momentary channel quality cannot be effective Reflect momentary channel quality, the most still change into averagely being obtained the MCS that benchmark MCS grade uses as user by long-time statistical The most useful grade.

Specifically, this MCS side-play amount can be positive offset amount, it is also possible to for negative side-play amount.

Alternatively, in one embodiment of the invention, terminal is used when sending this sub-frame of uplink on PUSCH MCS grade is the MCS grade obtained after this MCS side-play amount of MCS reference grade Downward addition.

Alternatively, in another embodiment of the present invention, terminal is used when sending this sub-frame of uplink on PUSCH MCS grade is the MCS grade obtained after MCS this MCS side-play amount of reference grade negative sense superposition.

In embodiments of the present invention, base station sets MCS according to the MCS grade used required for each sub-frame of uplink actual Offset value, MCS side-play amount is positive offset amount or negative side-play amount；It is by MCS reference grade Downward addition or negative sense superposition.

Specifically, in an example of the present invention, if 2 sub-frame of uplink of terminal scheduling, can uplink scheduling Grant information First stage uplink scheduling Grant information in use LTE system original MCS instructions field, use 5 bit to represent MCS benchmark Class information, as MCS reference grade may be configured as 10, for two sub-frame of uplink, for example, sub-frame of uplink A and sub-frame of uplink B, The most corresponding two second stage uplink scheduling Grant information, can be accurate at the second stage uplink scheduling of uplink scheduling Grant information It is 2 (corresponding sub-frame of uplink A) and 4 (corresponding sub-frame of uplink B) that information of being permitted setting is respectively provided with the value of MCS side-play amount, the most up The actually used MCS grade forward on the basis of benchmark MCS grade of subframe A adds up MCS side-play amount, namely 10 grades add up 2 etc. The MCS grade that level obtains being used when terminal finally sends sub-frame of uplink A is 12 grades, and last sub-frame of uplink B is actually used MCS grade forward on the basis of benchmark MCS grade adds up MCS side-play amount, namely 10 grades, 4 grades that add up obtain terminal and finally send out The MCS grade used when sending sub-frame of uplink B is 14 grades.

It can be seen that in the scheme of the present embodiment, after base station determines the sub-frame of uplink that terminal carries out uplink, generate with The uplink scheduling Grant information that scheduled sub-frame of uplink is corresponding, this uplink scheduling Grant information includes MCS class information, should MCS class information includes MCS reference grade and MCS side-play amount, and then this uplink scheduling Grant information is sent extremely by base station again Terminal, terminal, after receiving this uplink scheduling Grant information, obtains terminal according to MCS reference grade and MCS side-play amount and exists The MCS grade that PUSCH is used when sending sub-frame of uplink.The embodiment of the present invention is offset by design MCS reference grade and MCS Amount determines the MCS grade that terminal is used when sending each sub-frame of uplink, so that this MCS grade and terminal are at PUSCH The channel quality coupling of the sub-frame of uplink sent, improves systematic function and service efficiency.

The embodiment of the present invention additionally provides a kind of base station, including:

See the schematic block diagram that Fig. 3, Fig. 3 are a kind of base stations that the embodiment of the present invention provides.Implement for realizing the present invention Example is disclosed controls Information Design Methods.Wherein, as it is shown on figure 3, a kind of base station 300 that the embodiment of the present invention provides can be wrapped Include:

Determine unit 310, signal generating unit 320 and transmitting element 330.

Wherein it is determined that unit 310, for determining at least one sub-frame of uplink that terminal is transmitted.

Signal generating unit 320, at least one sub-frame of uplink generated and be scheduled at least one sub-frame of uplink described Corresponding uplink scheduling Grant information, described uplink scheduling Grant information includes MCS class information, described MCS class information bag Include MCS reference grade and MCS side-play amount.

Alternatively, in one embodiment of the invention, described MCS reference grade information is positioned at mandate auxiliary access The MCS instruction of first stage uplink scheduling Grant information described in (Licensed Assisted Access is called for short LAA) system Territory.

Transmitting element 330, for described uplink scheduling Grant information is sent to described terminal so that described terminal according to Described MCS reference grade and described MCS side-play amount obtain described terminal send on PUSCH described in be scheduled at least one The MCS grade used during sub-frame of uplink.

Alternatively, in some possible embodiments of the present invention, described transmitting element 330 specifically for:

Described first stage uplink scheduling Grant information is passed sequentially through with described second stage uplink scheduling Grant information Physical downlink control channel PDCCH sends to described terminal.

It can be seen that in the scheme of the present embodiment, base station 300 determines that terminal carries out at least one up son of uplink After frame, generate the uplink scheduling Grant information corresponding with at least one scheduled sub-frame of uplink, this uplink scheduling Grant information Including MCS class information, this MCS class information includes MCS reference grade and MCS side-play amount, and then base station is up by this again Scheduling grant information sends to terminal, terminal after receiving this uplink scheduling Grant information, according to MCS reference grade and MCS side-play amount obtains the MCS grade that terminal is used when PUSCH sends at least one sub-frame of uplink.The embodiment of the present invention is led to Cross design MCS reference grade and the MCS grade that used when sending each sub-frame of uplink to determine terminal of MCS side-play amount, from And the channel quality of the sub-frame of uplink that this MCS grade and terminal send at PUSCH is mated, improve systematic function and use effect Rate.
