The each embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, all other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.

Fig. 1 is a kind of flow diagram of the determination method of channel state information provided by the invention.The method can be as described below.

Step 101: user equipment (English: User Equipment;Abbreviation: UE) obtain instruction information.

Wherein, the instruction information, which is used to indicate base station and has robbed, accounts for first and exempts from licensed spectrum resource.

Optionally, the instruction information can be sent by base station by exempting from licensed spectrum resource, and/or be sent by base station by licensed spectrum resource.

What needs to be explained here is that base station, which is used to send, indicates that the licensed spectrum resource of exempting from of information can be first for having robbed and having accounted for and exempt from licensed spectrum resource, it is also possible to have robbed second accounted for and exempts from licensed spectrum resource, here without limitation.

It should be noted that first exempting from licensed spectrum resource and second and exempt from licensed spectrum resource and belong to different to exempt from licensed spectrum resource here.

In a step 101, UE obtains instruction information, comprising:

First way:

UE receives the instruction information that the transmission of licensed spectrum resource is exempted from by described first in the base station.

Wherein, at the time of sending the instruction information comprising the base station in the instruction information.

Specifically, the base station is by way of described first exempts from the instruction information of licensed spectrum resource transmission It may include at least one of following information:

Targeting signal;

Physical Downlink Control Channel (English: Physical Downlink Control Channel;Abbreviation: PDCCH) carrying Downlink Control Information (English: Downlink Control Information;Abbreviation: DCI);

Enhance Physical Downlink Control Channel (English: Enhanced Physical Downlink Control Channel;Abbreviation: EPDCCH) carrying DCI.

If the instruction information that the transmission of licensed spectrum resource is exempted from by described first in the base station is targeting signal, then the UE detects targeting signal, instruction information is obtained from the targeting signal detected.

It should be noted that if instruction information is obtained by detection targeting signal, then a kind of mode is, UE judges whether to get the instruction information by the presence or absence of detection targeting signal.That is, illustrating that UE gets the instruction information if UE detects that targeting signal exists, that is to say, that bright, base station, which is robbed, to account for first and exempt from licensed spectrum resource;In other words, if the base station is targeting signal by way of described first exempts from the instruction information of licensed spectrum resource transmission, so accordingly, " UE receives the instruction information that the transmission of licensed spectrum resource is exempted from by described first in the base station " can be understood as " UE receives the targeting signal that the transmission of licensed spectrum resource is exempted from by described first in the base station " in embodiments of the present invention, " at the time of sending the instruction information comprising the base station in the instruction information " can be understood as " sending instant of targeting signal, at the time of the as described base station sends the instruction information ", here the sending instant of targeting signal, it can be any moment for including from the finish time that the initial time that targeting signal is sent is sent to targeting signal.

It should be noted that if instruction information is obtained by detection targeting signal, then the signal sequence that UE can be made up of targeting signal in such a way that detection targeting signal obtains instruction information detection obtains instruction information.

What needs to be explained here is that, the signal sequence of targeting signal can include but is not limited to following sequence form: permanent envelope zero auto-correlation (English: Constant Amplitude Zero Auto Correlation, abbreviation: CAZAC) sequence, binary sequence, m-sequence, pseudo-random sequence, sequence, ZC (Zadoff-Chu) sequence that reference signal is constituted in LTE system.

And the reference signal in LTE system can include but is not limited to: primary synchronization signal (English: Primary Synchronization Signal;Abbreviation: PSS), secondary synchronization signal (English: Secondary Synchronization Signal;Abbreviation: SSS), cell specific reference signal (English: Cell-specific Reference Signal;Abbreviation: CRS), for Physical Downlink Shared Channel (English: Physical Downlink Shared Channel;Abbreviation: PDSCH) the UE specific reference signals (English: UE-specific Reference Signal) of data demodulation, the demodulated reference signal (English: Demodulation Reference Signal for enhanced Physical Downlink Control Channel EPDCCH demodulation;Abbreviation: DM-RS), location reference signals (English: Positioning Reference Signal;Abbreviation: PRS), channel state information reference signals (English: Channel State Information Reference Signal;Abbreviation: CSI-RS), discovery reference signal (English: Discovery Reference Signal;Abbreviation: DRS).

The targeting signal for carrying instruction information can occupy integer orthogonal frequency division multiplexing (English: Orthogonal Frequency Division Multiplexing in time;Abbreviation: OFDM) symbol, score OFDM symbol can also be occupied in time, can also occupy a part in setting OFDM symbol, can also be the integer or score OFDM symbol occupied in setting OFDM symbol;The targeting signal of instruction information is carried in its occupied each OFDM symbol or in each score OFDM symbol, the whole bandwidth for exempting from licensed spectrum resource can also be occupied on frequency domain, the fractional bandwidth for exempting from licensed spectrum resource can also be occupied on frequency domain, further, the targeting signal of instruction information is carried in its occupied different OFDM symbol or in different score OFDM symbols, the bandwidth for exempting from licensed spectrum resource occupied on frequency domain can be different, can also be identical, it is not specifically limited here.

It should be noted that, above-mentioned setting OFDM symbol may include having the OFDM symbol of specific OFDM symbol index, such as, if OFDM symbol is using normal cyclic prefix (Normal Cyclic Prefix), 14 OFDM symbols are so shared in a subframe, OFDM symbol index can be any integer in 0~13, the 1st OFDM symbol is respectively corresponded in a subframe to the 14th OFDM symbol, the OFDM symbol set at this time refers to the OFDM symbol that OFDM symbol index is #k, and wherein k can be any integer in 0~13.In embodiments of the present invention, setting OFDM symbol can be an OFDM symbol, is also possible to multiple OFDM symbols continuously or discontinuously, is not specifically limited here.

It should be noted that UE detects targeting signal when targeting signal is sent using multiple OFDM symbols in time, it also may include a part for only detecting targeting signal.

Such as, targeting signal is sent using multiple OFDM symbols in time, UE can only detect the signal that wherein 1 OFDM symbol is sent, account for exempting from licensed spectrum resource to judge whether the base station is robbed, if detecting the signal sent on the symbol, it then may determine that the base station is robbed and account for exempting from licensed spectrum resource, while the initial position that targeting signal is sent can be determined according to position of the symbol in all OFDM symbols that targeting signal occupies;Further, the OFDM symbol number that the position according to the symbol in all OFDM symbols that targeting signal occupies and targeting signal occupy can determine the end position that targeting signal is sent.The case where foregoing description sends targeting signal using multiple score OFDM symbols in time is also suitable.That is, if indicating, information is obtained by detection targeting signal, UE can obtain instruction information by signal of the detection targeting signal in part-time resource, further, obtain instruction information by the signal sequence that detection constitutes " signal of the targeting signal in part-time resource ", here time resource can be OFDM symbol, it is also possible to score OFDM symbol, can also be other times unit, be not specifically limited here, here signal sequence ibid describes, and does not repeat them here.

It should be noted that in embodiments of the present invention, the targeting signal for carrying instruction information can be understood as targeting signal.If the targeting signal exists, it is used to indicate base station and has robbed and account for the instruction information that first exempts from licensed spectrum resource and there is, that is to say, that if targeting signal exists, indicates that information there is.

It should be noted that, the effect of targeting signal may include at least one of following: instruction LTE equipment, which is robbed, accounts for exempting from licensed spectrum resource (or instruction LTE equipment can transmit data on exempting from licensed spectrum resource), LTE cell identification, coarse frequency synchronization, time slightly synchronize, and frequency fine is synchronous, time carefully synchronizes, CSI measurement, automatic growth control (Auto Gain Control, AGC) etc..

In embodiments of the present invention, the targeting signal for carrying instruction information can exempt from licensed spectrum resource by first and send.So UE detects targeting signal and accounts for exempting from licensed spectrum resource by judging that targeting signal whether there is to determine whether base station is robbed.If UE detects targeting signal, it is determined that base station, which has been robbed, accounts for exempting from licensed spectrum resource;If UE not yet detects targeting signal, it is determined that base station, which is not yet robbed, accounts for exempting from licensed spectrum resource.

If the instruction information that the transmission of licensed spectrum resource is exempted from by described first in the base station is DCI, the UE detects DCI, and instruction information is obtained from the DCI detected.

That is, UE can determine that the use chance for accounting for exempting from licensed spectrum resource has been robbed in base station when getting instruction information.

In embodiments of the present invention, the DCI for exempting from the transmission of licensed spectrum resource by described first, it can be carried in the PDCCH that described first exempts from the transmission of licensed spectrum resource, it can also be carried in the EPDCCH that described first exempts from the transmission of licensed spectrum resource, can also be carried in other channels such as physical down Traffic Channel PDSCH;The sub-frame boundary that the DCI for exempting from the transmission of licensed spectrum resource by described first can exempt from the corresponding carrier wave of licensed spectrum resource or cell first starts to send, and can also start to send among subframe.

It should be noted that referring to any position that a subframe includes into the subframe end boundary from subframe beginning boundary among subframe here.

Further, can also start to send in the OFDM symbol boundary of a certain fixation among subframe, to reduce the blind Detecting degree of being responsible for of UE.

It should be noted that DCI here can be located at public search space, the specific search space UE can also be located at, can UE to particular group it is effective, can also be only effective to single UE, or all UE that first community can be serviced effective.

Further, in order to reduce UE blind Detecting complexity, the format of DCI and/or comprising content can be and predefined, such UE can only detect the DCI with specific format and/or specific content, without detecting all possible DCI format and/or all possible DCI content.Further, carry what the initial position that the channel of DCI is sent was also possible to predefine, i.e. the initial position that the channel of carrying DCI is sent can be positioned at the OFDM symbol boundary set.

It may include at the time of what needs to be explained here is that sending the instruction information comprising the base station in the instruction information but be not limited to following several situations:

The first situation: base station rob account for use chance that first exempts from licensed spectrum resource when, exempt to send targeting signal in licensed spectrum resource by first, then at the time of the base station can be used as the base station transmission instruction information at the time of sending targeting signal.

In embodiments of the present invention, it can be at the time of the base station sends targeting signal and send any moment that the initial time of the targeting signal includes into the finish time for sending the targeting signal.

What needs to be explained here is that based on data transmission delay between UE and base station, at the time of UE can also be detected to being interpreted as the base station at the time of targeting signal sends targeting signal here.

As shown in Fig. 2, for will rob account for first exempt from licensed spectrum resource at the time of as the schematic diagram of the starting sending instant of targeting signal.

When beginning boundary at the time of first accounted for exempts to send targeting signal in licensed spectrum resource for OFDM symbol has been robbed in base station, then the starting sending instant of targeting signal is as shown in Figure 3.

Specifically, base station is after robbing and accounting for exempting from licensed spectrum resource, since rob account for exempting from licensed spectrum resource at the time of, to etc. targeting signal to be sent at the time of arrive before, send pre- Seize ACK message, the main function of pre- Seize ACK message is that the characterization base station has occupied this and exempts from licensed spectrum resource, it may not be necessary to which user equipment detects it.The corresponding prevailing scenario of pre- Seize ACK message is, it is predefined for exempting from the initial time that data are transmitted in licensed spectrum resource, for example, initial time is sub-frame boundary, character boundary, boundary of time slot, data here include targeting signal, reference signal, control channel, data channel etc..Simultaneously, base station, which is robbed, to be accounted for exempting from being arbitrary at the time of licensed spectrum resource, it can be any time in a subframe, any time being also possible in a symbol can also be any time in a time slot, in this case, base station is after robbing and accounting for exempting from licensed spectrum resource, before the initial time for waiting pending datas to transmit arrives, in order to guarantee to the occupancy for exempting from licensed spectrum resource, in above-mentioned time range, pre- Seize ACK message can be sent.

Second case: base station send instruction information at the time of can also be base station it is practical transmission data initial time, this moment relative to rob account for first exempt from licensed spectrum resource use chance at the time of want more late.Here the data actually sent may include PDCCH, PDSCH, EPDCCH etc..

The second way:

UE receives the base station and passes through licensed spectrum resource and/or robbed the cross-carrier signaling that second accounted for exempts from the transmission of licensed spectrum resource.

Wherein, the instruction information sent in the cross-carrier signaling comprising the base station.

The UE obtains the instruction information that the base station is sent from the cross-carrier signaling received.

Wherein, the time quantum comprising base station instruction in the instruction information.

That is, LTE equipment (or base station) is when robbing the use chance for accounting for exempting from licensed spectrum resource, cross-carrier signaling can be sent on exempting from licensed spectrum resource/licensed spectrum resource, in this way, UE can obtain instruction information by detecting cross-carrier signaling.

Specifically, the base station may include at least one of following instruction information licensed spectrum resource and/or by way of having robbed the cross-carrier signaling that account for second exempts from the transmission of licensed spectrum resource, and instruction information here may include following at least one in other words:

The DCI of PDCCH carrying;

The DCI of EPDCCH carrying.

It should also be noted that, the time quantum for the base station instruction being related to includes at least one of following information:

At the time of the base station is exempted from licensed spectrum resource using described first and is carried out data transmission;

At the time of licensed spectrum resource progress data dispatch is exempted from using described first to UE in the base station.

It should be noted that data here can be reference signal, the data of data channel carrying are also possible to targeting signal.Reference signal can be with as described above, being not specifically limited in embodiments of the present invention, data channel can be PDCCH, PDSCH, EPDCCH, Physical Broadcast Channel (English: Physical Multicast Channel;Abbreviation: PMCH) etc..

It should be noted that, it can be sub-frame boundary at the time of including in the time quantum of the base station instruction, be also possible to character boundary, be also possible to boundary of time slot, as shown in figure 4, for the schematic diagram at the time of including in the time quantum of base station instruction being sub-frame boundary;As shown in figure 5, for the schematic diagram at the time of including in the time quantum of base station instruction being character boundary.

It should be noted that Fig. 4 and Fig. 5 are illustrated for indicating that information is sent by licensed spectrum resource, it can equally be well applied to instruction information by second and exempt from the case where licensed spectrum resource is sent.In figures 4 and 5, the main function of pre- Seize ACK message is so that base station is after robbing and accounting for exempting from licensed spectrum resource, before data start transmission, it can also be with busy channel, here data can be reference signal, and the data of data channel carrying are also possible to targeting signal.

Optionally, in embodiments of the present invention, UE, can before the content for detecting cross-carrier signaling bear First to cache the first data for exempting from licensed spectrum resource, the content of cross-carrier signaling bear is then detected again, and the time quantum of the cross-carrier signaling instruction can be located within the data of caching.This scene for first caching the method detected afterwards especially suitable for starting transmission among subframe when the first data for exempting from licensed spectrum resource.

The third method:

UE receives the control information that the transmission of licensed spectrum resource is exempted from by described first in the base station.

Wherein, the instruction information sent in the control information comprising the base station.

The UE obtains the instruction information that the base station is sent from the control information received.

Wherein, the time quantum comprising base station instruction in the instruction information.

Here control information can be DCI, be also possible to other information, here without limitation.

It should also be noted that, the time quantum for the base station instruction being related to includes at least one of following information:

At the time of the base station is exempted from licensed spectrum resource using described first and is carried out data transmission;

At the time of licensed spectrum resource progress data dispatch is exempted from using described first to UE in the base station.

At the time of base station described here is exempted from licensed spectrum resource using described first and is carried out data transmission, it can be any moment for including from moment T1 to moment T2, wherein, moment T1, which can correspond to the base station and rob, accounts for the described first initial time for exempting from licensed spectrum resource, and moment T2 can correspond to the base station at the time of described first exempts to terminate in licensed spectrum resource data transmission;Moment T2 can also correspond to the base station do not need again through listen to obtain described first and exempt from licensed spectrum resource transmission chance in the case where, at the time of can be used described first and exempt from corresponding to the maximum time of licensed spectrum resource.

Such as, it accounts for first assuming that the base station is robbed at the T1 moment and exempts from licensed spectrum resource, do not need again through listen to using described first exempt from licensed spectrum resource maximum duration be x milliseconds, then moment T2 can correspond to (T1+x milliseconds) it is corresponding at the time of.

In other words, at the time of the base station is exempted from licensed spectrum resource using described first and is carried out data transmission, it can be the base station and account for described first and exempt from after licensed spectrum resource and before terminating to exempt from licensed spectrum resource using described first any time for including in the time robbing, during this period of time, the base station, which does not need to listen to again, obtains the described first use chance for exempting from licensed spectrum resource.

At the time of licensed spectrum resource progress data dispatch is exempted from using described first to UE in the base station, it can be the base station and exempt from the initial time that licensed spectrum resource carries out data dispatch to UE using described first, such as, sub-frame boundary, orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) character boundary, boundary time slot (Slot) etc..Scheduled data can be PDSCH etc..It should be noted that, in embodiments of the present invention, UE is before the control information that the transmission of licensed spectrum resource is exempted from detection described first, the first data for exempting from licensed spectrum resource can first be cached, then the described first control information for exempting from the transmission of licensed spectrum resource is detected again, and the described first time quantum for exempting from the control information instruction of licensed spectrum resource transmission can be located within the data of caching.This scene for first caching the method detected afterwards especially suitable for starting transmission among subframe when the first data for exempting from licensed spectrum resource.

Step 102: the UE determines reference time point according to the instruction information got.

Wherein, reference time point can be used for characterizing base station after robbing and accounting for exempting from the use chance of licensed spectrum resource, at the time of first exempts from licensed spectrum transmitted over resources data.

In this way, UE, which passes through, determines reference time point, determines to be robbed first accounted for by base station and exempt from licensed spectrum resource precision of channel state information when carrying out data transmission and lay the foundation for subsequent effectively promoted.

In a step 102, the UE determines that the reference time mode of point includes but is not limited to according to the instruction information got:

First way:

If send the instruction information comprising the base station in the instruction information, the UE determines reference time point according to the instruction information got, comprising:

At the time of the UE is according to including that the base station sends the instruction information in the instruction information got, reference time point is determined.

Specifically, it is determined as reference time point at the time of the base station is sent the instruction information by the UE.

What needs to be explained here is that base station described here may include at the time of sending the instruction information but be not limited to following several situations at the time of sending the instruction information comprising the base station in the instruction information:

The first situation: base station rob account for use chance that first exempts from licensed spectrum resource when, pass through One exempts to send targeting signal in licensed spectrum resource, at the time of the so described base station can be used as the base station transmission instruction information at the time of sending targeting signal, it can be at the time of sending targeting signal here and send any moment that the initial time of targeting signal includes into the finish time for sending targeting signal.

What needs to be explained here is that based on data transmission delay between UE and base station, at the time of UE can also be detected to being interpreted as the base station at the time of targeting signal sends targeting signal here.

Specifically, base station can occupy integer OFDM symbol at the time of sending the targeting signal in time-domain resource, score OFDM symbol can also be occupied, a part in setting OFDM symbol can also be occupied, can also be the integer or score OFDM symbol occupied in setting OFDM symbol.

Second case: base station send instruction information at the time of can also be base station it is practical transmission data initial time, this moment relative to rob account for first exempt from licensed spectrum resource use chance at the time of want more late.

Specifically, base station is robbed by energy measuring and/or signal resolution and accounts for the first use chance for exempting from licensed spectrum resource, base station before transmitting data, sends pre- Seize ACK message first, retransmits instruction information.

Specifically, base station is after robbing and accounting for exempting from licensed spectrum resource, since rob account for exempting from licensed spectrum resource at the time of, before the initial time of equal pending datas transmission arrives, send pre- Seize ACK message, the main function of pre- Seize ACK message is that the characterization base station has occupied this and exempts from licensed spectrum resource, it may not be necessary to which user equipment detects it.When the corresponding prevailing scenario of pre- Seize ACK message, the initial time of data transmission is predefined, for example, sub-frame boundary, character boundary, boundary of time slot, base station, which is robbed, simultaneously accounts for exempting from being arbitrary at the time of licensed spectrum resource, it can be any time in a subframe, the any time being also possible in a symbol, it can also be any time in a time slot, in this case, base station is after robbing and accounting for exempting from licensed spectrum resource, before the initial time of equal pending datas transmission arrives, in order to guarantee to the occupancy for exempting from licensed spectrum resource, in above-mentioned time range, pre- Seize ACK message can be sent.

It should be noted that the pre- Seize ACK message can be a part of targeting signal, it is also possible to other signals, here without limitation.

It can be seen that the base station can be base station at the time of sending the instruction information account for first robbing At the time of exempting to send targeting signal when licensed spectrum resource;Can also be base station rob account for first exempt from licensed spectrum resource when the practical initial time for sending data.

That is, the reference time point that UE is determined at the time of sending the instruction information by the base station includes but is not limited to:

Base station rob account for first exempt from licensed spectrum resource when send targeting signal at the time of;

Base station rob account for first exempt from licensed spectrum resource when the practical initial time for sending data.

Optionally, the reference time point that UE is determined at the time of sending the instruction information by the base station can also include, base station rob account for first exempt from licensed spectrum resource when the practical initial time for the sending data any moment that includes into the practical finish time for sending data.

Optionally, if the base station send it is described instruction information at the time of for the base station it is practical transmission data initial time, since the initial time for sending data is related to data characteristics is sent, such as: if the data sent are targeting signal, the initial time for sending data can be the beginning boundary of OFDM symbol;If the data sent are that control data and/or business datum, the initial time for sending data can be the beginning boundary of subframe, be also possible to the beginning boundary of time slot.

Such as: control data and/or business datum can be with are as follows: the data of PDCCH carrying, the data of EPDCCH carrying, the data of PDSCH carrying, the data of PMCH carrying.

It should be noted that the initial time for sending data can also be robbed according to base station and account for first and exempt to be adjusted at the time of licensed spectrum resource.Such as: it is the beginning boundary of a subframe that base station, which is robbed and accounts for first at the time of exempt from licensed spectrum resource, and base station will send targeting signal before sending data every time, then base station sends targeting signal since the boundary of the subframe, after sending targeting signal, then start to send control data and/or business datum;Alternatively,

It is the beginning boundary of a subframe that base station, which is robbed and accounts for first at the time of exempt from licensed spectrum resource, and base station is since the beginning boundary of the subframe, targeting signal and control data are sent simultaneously, perhaps targeting signal and business datum are sent simultaneously or send targeting signal, control data and business datum simultaneously.At this point, base station can be using the orthogonal separately send targeting signals of modes such as frequency division multiplexing, code division multiplexing, control data, business datum when executing data and sending.

The second way:

If send the instruction information comprising the base station in the instruction information, the UE determines reference time point according to the instruction information got, comprising:

At the time of the base station of corresponding relationship and acquisition between at the time of the UE sends the instruction information according to preset reference time point and the base station sends the instruction information, reference time point is determined.

Such as: the corresponding relationship between at the time of preset reference time point and the base station send the instruction information be reference time point and at the time of the base station sends the instruction information between be spaced predefined duration, i.e., will duration predefined with interval at the time of the transmission instruction information of the base station at the time of as reference time point.Specifically, reference time point can be at the time of the predefined duration before at the time of the base station sends the instruction information corresponds to;Can also the base station send it is described instruction information at the time of after predefined duration correspond at the time of, here without limitation.

For example, targeting signal occupies 4 OFDM symbols in time, UE only can be located at the first signal that the 2nd OFDM symbol is sent by detection, wherein the first signal is a part of targeting signal, determines that the base station is robbed and accounts for exempting from licensed spectrum resource.That is, at this point, the base station that UE is detected can be the time location in 4 OFDM symbols that targeting signal includes where the 2nd OFDM symbol at the time of sending the instruction information.Such as, it is indicated with the notation index of the 2nd OFDM symbol, predefined duration can be 1 OFDM symbol, and defining reference time point is before at the time of the base station sends the instruction information, then UE can determine that reference time point is the 1st OFDM symbol in 4 OFDM symbols that targeting signal occupies in time;Or predefined duration can be 3 OFDM symbols, and define reference time point be the base station send the instruction information at the time of after, then at the time of UE can determine that reference time point is that the end position of targeting signal in time corresponds to.Reference time point as shown in FIG. 6 can be from the starting of targeting signal and send the time point that position can be identified to any one UE terminated transmission position (starting including targeting signal sends position and terminates to send position), such as OFDM symbol boundary, the inverse of sample rate employed in score OFDM symbol boundary and integer LTE system.

It should be noted that the expression of integer OFDM symbol can be used in predefined duration, it is also possible to indicate using score OFDM symbol, wherein the number of score OFDM symbol can be 1 It can be multiple.

It should be noted that, at the time of the base station of corresponding relationship and acquisition between at the time of sending the instruction information according to preset reference time point and the base station sends the instruction information, determine reference time point, it is also possible that base station described in distance sends OFDM symbol boundary or score OFDM symbol boundary or boundary of time slot or sub-frame boundary nearest at the time of the instruction information as reference time point before or after at the time of the base station is sent the instruction information.

What needs to be explained here is that determining may include the two kinds of situations recorded in first way at the time of base station sends instruction information, and which is not described herein again in the second way.

The third mode:

If the time quantum comprising base station instruction in the instruction information, the UE determine reference time point according to the instruction information got, comprising:

The UE determines reference time point according to the time quantum for the base station instruction for including in the instruction information got.

Wherein, the time quantum of the base station instruction includes at least one of following information:

At the time of the base station is exempted from licensed spectrum resource using described first and is carried out data transmission;

At the time of licensed spectrum resource progress data dispatch is exempted from using described first to UE in the base station.

Generally, if the chronomere of base station instruction is that the base station is exempted from licensed spectrum resource using described first and carried out data transmission, as previously described, it can be any moment for including from moment T1 to moment T2, wherein moment T1, which can correspond to the base station and rob, accounts for the described first initial time for exempting from licensed spectrum resource, and moment T2 can correspond to the base station at the time of described first exempts to terminate in licensed spectrum resource data transmission;Moment T2 can also correspond to the base station do not need again through listen to obtain described first and exempt from licensed spectrum resource transmission chance in the case where, at the time of can be used described first and exempt from corresponding to the maximum time of licensed spectrum resource.

At the time of licensed spectrum resource progress data dispatch is exempted from using described first to UE in the base station, it can be the base station and exempt from the initial time that licensed spectrum resource carries out data dispatch to UE using described first, such as, sub-frame boundary, orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) character boundary, boundary time slot (Slot) etc..Scheduled data can be PDSCH etc..

Specifically, if the time quantum of the base station instruction exempts from the initial time that licensed spectrum resource carries out data transmission using described first for the base station, then initial time that licensed spectrum resource carries out data transmission is exempted from sub-frame boundary using described first in the base station, or in boundary of time slot, or on presetting OFDM symbol boundary, the complexity that UE carries out blind Detecting to the initial time for exempting from licensed spectrum resource transmission data is effectively reduced in this way.

If the time quantum of the base station instruction is that licensed spectrum resource transmission targeting signal is exempted from using described first in the base station, then initial time that licensed spectrum resource carries out data transmission is exempted from OFDM symbol boundary, or on score OFDM symbol boundary using described first in the base station.Specifically, the base station using described first exempt from the time of licensed spectrum resource sends targeting signal can for since rob account for exempting from licensed spectrum resource after and distance rob and account for exempting from the time of licensed spectrum resource correspond to nearest data transmission initial position (such as: OFDM symbol boundary), terminate to the initial position of next nearest sub-frame boundary.

It should be noted that, the time quantum of the base station instruction can also extremely send the identifiable time location of any one UE between the end position of targeting signal for the initial position of transmission targeting signal, the position that UE can be identified can use OFDM symbol boundary, the integral multiple of score OFDM symbol boundary and sample rate inverse.

Optionally, if the time quantum of the base station instruction is the identifiable time location of any one UE sent between the initial position extremely end position of transmission targeting signal of targeting signal, then UE can cache the data for exempting to transmit in licensed spectrum resource before instruction information, the instruction information can be sent by least one in following resource: licensed spectrum resource, it has robbed second accounted for and has exempted from licensed spectrum resource, first exempts from licensed spectrum resource.

4th kind of mode:

UE exempts from the PDCCH in licensed spectrum resource by detection, using the time location of the DCI instruction of PDCCH carrying as reference time point.Or UE exempts from the EPDCCH in licensed spectrum resource by detection, using the time location of the DCI instruction of EPDCCH carrying as reference time point.

Wherein, the time location of DCI instruction can send the occupied time location of DCI for PDCCH, be also possible to EPDCCH and send the occupied time location of DCI, be also possible to its of PDCCH instruction His time location is also possible to the other times position of EPDCCH instruction, here without limitation.

Specifically, in order to reduce the complexity of UE blind Detecting, the time location for exempting from PDCCH or EPDCCH in licensed spectrum resource can be preset.Such as: the initial position of PDCCH is on preset OFDM symbol boundary, or the initial position of PDCCH is on the boundary of subframe, or the initial position of PDCCH is on the boundary of time slot, or the initial position of PDCCH is in the fixation position of a subframe, again for example: fixed position can be the corresponding time location of 1/N subframe lengths referred in a subframe, the corresponding time location of 2/N subframe lengths etc. in a subframe.

In addition, can also pre-define the format of PDCCH to reduce the complexity of UE blind Detecting, UE can be detected PDCCH in conjunction with the initial position of predefined PDCCH and the format of predefined PDCCH;If detecting the PDCCH of predefined format on predefined position, it can determine that base station is robbed and account for exempting from licensed spectrum resource, and determine the initial position of PDCCH, and using the initial position of determining PDCCH as reference time point.

As shown in fig. 7, the schematic diagram of the initial position for PDCCH.

Step 103: the UE determines reference resources according to the reference time point.

Wherein, the reference resources are for determining that the channel status that described first accounted for exempts from licensed spectrum resource respective channels has been robbed in the base station.

In step 103, the UE determines reference resources according to the reference time point, which can be a complete subframe in time.

It should be noted that reference resources may include time-domain resource, it can also include frequency domain resource, also may include code domain resource, here without limitation.

Specifically, the UE determines that the mode of reference resources includes but is not limited to according to the reference time point:

First way:

The UE selects the distance between described reference time point satisfaction to set the corresponding time-domain resource of the time quantum of first threshold as reference resources according to the reference time point.

Wherein, setting first threshold can be also possible to integer OFDM symbol or score OFDM symbol, can also be other according to the minimum distance value determined with the distance between the reference time point The form of expression, here without limitation.

Such as: the UE is according to the reference time point, and after the reference time point, the time quantum corresponding time-domain resource nearest apart from the reference time point is as reference resources.

The UE is according to the reference time point, using the corresponding time-domain resource of time quantum comprising the reference time point as reference resources.

Time quantum mentioned here can be any one of radio frames, subframe, time slot, OFDM symbol.

In this way, since determining reference time point and first exempts from the initial time that licensed spectrum resource carries out data transmission there are incidence relations, or the reference time point determined exempts from the initial time that licensed spectrum resource carries out data transmission comprising first, within a period of time after reference time point, base station will use this first to exempt from licensed spectrum resource and carry out data transmission with UE.So, using the nearest corresponding time-domain resource of a time quantum after reference time point or the corresponding time-domain resource of a time quantum including reference time point as reference resources, it can guarantee that the reference resources are located at base station and UE and exempt within the time range of licensed spectrum resource progress data communication using first, simultaneously because according to distance reference time point nearest principle and the principle including reference time point, determine reference resources, UE is when exempting from the corresponding channel of licensed spectrum resource to first using reference resources and measuring, exempt from licensed spectrum resource practical occupied time without obtaining first, save signaling overheads, reduce the content of UE detection, help to improve the measurement accuracy of channel state information.

It should be noted that, in embodiments of the present invention, determining reference resources are mainly described from time-domain resource angle, the resource that reference resources are occupied on frequency domain, e.g. first exempts from corresponding whole frequency resource or the component frequency resource in the time-domain resource of licensed spectrum resource, in embodiments of the present invention, it is not specifically limited.

The second way:

The UE receives the resource information for reporting status information of channel that the base station is sent.

It wherein, include time-domain resource in the resource information.

The UE determines reference resources according to the time-domain resource and the corresponding time-domain resource of reference time point that include in the resource information.

It should be noted that, the corresponding time-domain resource of the reference time point recited herein can be the corresponding time-domain resource of time quantum comprising the reference time point, it can also be the time quantum corresponding time-domain resource nearest apart from the reference time point, be not specifically limited here.The time quantum is same as above, it can be any one of radio frames, subframe, time slot, OFDM symbol, correspondingly, the time-domain resource that time-domain resource, the OFDM symbol that the corresponding time-domain resource of the time quantum can be the time-domain resource that time-domain resource, the subframe that radio frames include include, time slot includes include, this will not be repeated here.

Wherein, the time-domain resource corresponding time point for including in the reference resources lags behind the reference time point.It should be noted that, if the time-domain resource that the reference resources include is the corresponding time-domain resource of a subframe, the time-domain resource that the reference resources include corresponding time point can be the beginning boundary of the subframe to any moment for including between the end boundary of the subframe;If the time-domain resource that the reference resources include is the corresponding time-domain resource of a time slot, the time-domain resource that the reference resources include corresponding time point can be the beginning boundary of the time slot to any moment for including between the end boundary of the time slot;If the time-domain resource that the reference resources include is the corresponding time-domain resource of multiple OFDM symbols, the time-domain resource that the reference resources include corresponding time point can be the beginning boundaries of multiple OFDM symbols to any moment for including between the end boundary of multiple OFDM symbol.

The UE, which receives the time-domain resource corresponding time for including in the resource information for reporting status information of channel that the base station is sent, can be to rob in base station and accounts for being also possible within the time range using chance that first exempts from licensed spectrum resource not robbing in base station accounting for except the range using chance that first exempts from licensed spectrum resource.

The reference resources corresponding time that the UE is determined, which can be base station, robs and accounts within the time range using chance that first exempts from licensed spectrum resource.

Subframe expression can be used in the time-domain resource for including in the resource information, is also possible to other representations, such as: OFDM symbol indicates, time slot indicates, radio frames indicate etc..

The frequency domain resource for including in the resource information includes the corresponding frequency domain resource of the occupied frequency location of UE reporting status information of channel, includes a continuous or discrete subcarrier of integer, a continuous or discrete resource element (English: Resource Element of integer;Abbreviation: RE), integer provide Source block (English: Resource Block: abbreviation: RB) etc., in embodiments of the present invention, is not specifically limited.

The mode that the UE receives the resource information for reporting status information of channel that the base station is sent can be by physical layer signaling, RRC signaling, MAC signaling etc..

Implement in step 103 it should be noted that the UE receives the resource information for reporting status information of channel that the base station is sent and can be, be also possible to before step 101 or step 102, among or implement later, be not specifically limited here.

Specifically, the UE selects to meet the time-domain resource to impose a condition as reference resources from all time-domain resources for including the time-domain resource that the corresponding time-domain resource of the reference time point includes into the resource information.

It should be noted that the chronomere where assuming the corresponding time-domain resource of the reference time point can be indicated using subframe, for example, the subframe index of the used subframe of chronomere where the corresponding time-domain resource of reference time point is the subframe of #k;Chronomere where the time-domain resource for including in the resource information can also be indicated using subframe, such as, subframe index used in chronomere where the time-domain resource for including in the resource information is the subframe of #m, wherein, subframe index #k and subframe index #m can be indicated by wireless frame index and time slot index, that is, be passed throughIt indicates, wherein nfIndicate wireless frame index, value range from 0 to 10239 in any one integer value, nsIndicate time slot index, value range from 0 to 19 in any one integer value,Expression is rounded downwards x.So from all time-domain resources for including the time-domain resource that the corresponding time-domain resource of the reference time point includes into the resource information, may include since subframe index be #k subframe terminate to the subframe that subframe index is #m, the time-domain resource that included all subframes include.

Wherein, described to impose a condition comprising at least one of the following conditions:

Condition one: meet setting second threshold with the distance between the time-domain resource for including in the resource information, and be located at after the corresponding time-domain resource of the reference time point, and be located at before the time-domain resource in the resource information included.

Here the second threshold set can satisfy UE from based on reference resources determine channel state information to The channel state information, the time of required consumption are reported, such as can be 4 subframe lengths, is also possible to 2 subframe lengths etc..

Specifically, the UE carries out channel measurement and/or interference measurement to the determining time-domain resource respectively;

And/or the UE carries out channel measurement and/or interference measurement to the determining frequency domain resource respectively.

According to channel measurement and/or interference measurement results, exempt from the channel state information of licensed spectrum resource respective channels described in determination.

When time difference of the UE between the time-domain resource that includes in the time-domain resource corresponding time and the resource information for including in the reference resources corresponding time is not less than setting third threshold value, channel state information that the channel state information for exempting from licensed spectrum resource respective channels of configuration is exempted from into licensed spectrum resource respective channels as described first.

The channel state information for exempting from licensed spectrum resource respective channels of the UE configuration, comprising:

The UE receives the specific signaling that the base station is sent.

Wherein, the channel state information for exempting from licensed spectrum resource respective channels comprising configuration in the specific signaling.

The form of the specific signaling includes at least one of following signalling format:

Physical layer signaling, media access control MAC signaling, radio resource control RRC signaling.

Alternatively, specific signaling can also be provided by standard agreement, predefined mode makes UE determine the channel state information for exempting from licensed spectrum resource respective channels of configuration.

Optionally, the UE determines the channel state information for exempting from licensed spectrum resource respective channels of configuration, comprising:

The UE receives the instruction information that the base station is sent.

Wherein, the channel status for exempting from licensed spectrum resource respective channels comprising configuration in the instruction information Information.

Optionally, when time difference of the UE between the time-domain resource that includes in the time-domain resource corresponding time and the resource information for including in the reference resources corresponding time is not less than setting third threshold value, according to the reference resources of configuration and exempt from the corresponding relationship between the channel state informations of licensed spectrum resource respective channels and the reference resources of determination, obtains the described first channel state information for exempting from licensed spectrum resource respective channels.

That is, base station can configure the corresponding channel state information of multiple reference resources, the corresponding channel state information of a reference resources can also be configured, is not specifically limited here.

In embodiments of the present invention, described first channel state information for exempting from licensed spectrum resource respective channels can be indicated by indexing correspondingly with channel state information, such as, utilize channel quality instruction (English: Channel Quality Indicator, abbreviation: CQI) it indexes to indicate, the channel state information for exempting from licensed spectrum resource respective channels of configuration can be in existing LTE system, it is indicated with specific CQI index, such as: CQI index 0, CQI index 1, or other CQI indexes, optionally, the CQI index of configuration, if can satisfy base station to be scheduled UE using the corresponding channel state information of CQI index of configuration, it can guarantee the first biography success rate of the data transmission such as downlink data transmission between base station and UE Not less than a certain thresholding, such as 90%.

Optionally, specific CQI index may also be distinct from that the CQI index supported in existing LTE system, it can be indicated with specific CQI index, UE is not less than the third threshold value of setting in the time difference of the reference resources for reporting resource and specific CQI index that correspond to specific CQI index reported between resource, it base station can be according to specific CQI index, channel state information inaccuracy determined by confirmation reference resources corresponding with resource is currently reported, alternatively, the reference resources and reporting time difference between resource not less than the third threshold value of setting.Particularly, specific CQI index can be different from the CQI index 0 supported in existing LTE system, this is because, if current UE reports CQI index 0, when reporting CQI index 0 especially for auxiliary serving cell, the base station of auxiliary serving cell subordinate may determine that UE to the Radio Link Detection (English: Radio Link Monitoring of auxiliary serving cell, abbreviation: RLM) failure, so if multiplexing CQI index 0, base station erroneous judgement auxiliary serving cell Radio Link Failure may be enabled, so the specific CQI index different from CQI index 0 can be introduced, so that base station not only can correctly judge Auxiliary serving cell whether Radio Link Failure, can also judge to report the relationship between the third threshold value of the relationship and setting between the time difference between resource and corresponding reference resources.

Specifically, the UE includes, but are not limited to, the following ways the mode that the determining channel state information is sent to the base station:

First way:

The channel state information that the UE periodic report determines.

Specifically, it is assumed that in step 103, reference resources are determined by the way of the condition that meets three, and obtain the channel state information between the base station and the UE according to determining reference resources, as shown in figure 8, for the structural schematic diagram of determining reference resources position.

As can be seen from Figure 8, it is assumed that the time resource of reporting status information of channel can be located at licensed spectrum resource, can also be located at and exempt from licensed spectrum resource, be indicated respectively with time resource 1, time resource 2, time resource 3.

The time location for accounting for exempting from licensed spectrum resource is robbed marked as the dash area of " 4 " and " 5 " expression base station, wherein include reference resources in the corresponding resource of the time location of " 4 " and " 5 ".

When UE is in 1 reporting status information of channel of time resource, it can be according to the reference resources for including in Distance Time resource 1 nearest " 4 ", determine channel state information, here the mode of channel state information is determined, it is that UE can use the reference resources for including in time resource " 4 ", carries out channel and/or interference measurement;

Similarly, UE can determine channel state information according to the reference resources for including in Distance Time resource 2 nearest " 5 " in 2 reporting status information of channel of time resource;

Further, UE also can use the reference resources for including in " 4 " and " 5 ", determine channel state information jointly, such as the measurement result (such as interference I) of " 4 " and " 5 " corresponding reference resources is averaged.

When UE is in 3 reporting status information of channel of time resource, the time interval between the nearest time resource of Distance Time resource 3 " 5 " and time resource " 3 " is more than third threshold value, at this point, UE can report the channel state information of a configuration on time resource 3.

This have the advantage that if reference resources that distance reports resource nearest and reporting between resource Time interval be more than third threshold value, then illustrate, even if UE obtains channel state information according to the reference resources measurement at this time, and the reporting source of channel state information for determining this, but due to the channel state information based on reference resources and report the time interval between resource too long, the channel state information reported can not also reflect the channel status for reporting resource to exempt from licensed spectrum between base station and UE later, therefore, in order to save the operation at the end UE, in this case, UE can be enabled to measure without channel state information, and directly report the channel state information of configuration.

It should be noted that, resource 6 is reported for what is occurred after reporting resource 3, if can find correspondence reports the effective reference resources of resource 6, such as reference resources that distance reports resource 6 nearest (being located at time resource " 7 ") and the time interval between resource is reported to be not above third threshold value, so UE can be according to the reference resources for including in " 7 " as shown in Figure 9, channel and/or interference measurement are carried out, is determined in the channel state information for reporting resource 6 to be reported.For LTE system, the channel state information of UE successive periodic report in time can have certain connection, such as UE calculates CQI according to RI or PMI.So UE can be related to the channel state information of previous configuration in the channel state information for reporting resource 6 to report, can also be unrelated.

Specifically, for situation shown in Fig. 9, there may be a problems, just assume that UE indicates Whole frequency band channel state information in the channel state information for reporting resource 3 to report, more than third threshold value, the order instruction for reporting resource 3 to report is (English: Rank Indication with the distance between resource " 3 " is reported for the reference resources (being located at time resource " 5 ") for reporting resource 3 nearest due to distance;Abbreviation: RI) it is the channel state information configured, UE reports resource 6 to report pre-coding matrix instruction (English: Precoding Matrix Indicator abbreviation: PMI) and/or CQI at this time, it can be calculated based on the RI for the configuration for reporting resource 3 to report, can also RI be recalculated according to the reference resources that " 7 " include again, and based on the RI recalculated, PMI and/or CQI information are calculated.

It is corresponding, resource 6 is reported, UE can first report the RI recalculated based on " 7 ", then other after reporting resource 6 report resource, PMI and/or CQI is reported, also or, the channel state information recalculated according to " 7 " can be included directly that PMI, RI, CQI are reported by UE.In this manner, if UE is based on the reference resources that time resource " 7 " include and recalculates channel state information, and there is no the channel status for the corresponding configuration of reference resources for including using time resource " 5 " Information, it is also necessary to notify eNB using which kind of above-mentioned reporting schemes.

The second way:

The UE is aperiodic to report the determining channel state information.

Specifically, the concrete mode of the aperiodic reporting status information of channel of UE is similar with the concrete mode of periodic report channel state information.

But, for the UE with CA ability, base station, which can configure UE by RRC signaling, has multiple serving cells (serving cells), and base station can trigger signaling triggering UE by aperiodic channel status information and report the channel state information obtained to multiple serving cell measurements.

For the serving cell of carrying aperiodic channel status information triggering signaling, corresponding rob accounts for exempting from licensed spectrum resource, and other serving cells for being indicated in the triggering signaling, due to exempting from the random use of licensed spectrum resource, it may not rob and account for exempting from licensed spectrum resource, therefore for not robbing other serving cells for accounting for exempting from licensed spectrum resource and belonging to triggering reporting source of channel state information again, UE is also required to the mode for the determination reference resources mentioned in through the embodiment of the present invention, determines channel state information.

Scheme through the embodiment of the present invention, UE obtain instruction information, and the instruction information, which is used to indicate base station, has robbed and account for first and exempt from licensed spectrum resource;According to the instruction information got, reference time point is determined;According to the reference time point, reference resources are determined, the reference resources are for measuring the channel status that described first for having robbed and having accounted for exempts from licensed spectrum resource respective channels;According to the reference resources, the described first channel state information for exempting from licensed spectrum resource respective channels is determined, and the determining channel state information is sent to the base station.In this way, in the case where exempting from licensed spectrum resource opportunities use, UE determines reference time point according to the instruction information that base station is sent in real time, and then determine the reference resources that the channel status for exempting from licensed spectrum resource respective channels accounted for is robbed for measuring base station, the reference resources determined to rob the licensed spectrum resource of exempting from accounted for according to base station to be adjusted flexibly, UE is set to accurately determine out the channel state information that channel corresponding with licensed spectrum resource is exempted from matches, improve the precision of channel state information measurement, it is effective to guarantee using the data transmission efficiency for exempting from licensed spectrum resource.
