Fig. 6 is a kind of data sending, receiving method provided in an embodiment of the present invention, the specific steps are as follows:

Step 61, base station determines each carrier wave for belonging to the scheduling carrier wave set and belongs to the scheduling carrier wave set The priority orders of each carrier wave.

Step 62, base station sends the first instruction information to user equipment.

The scheduling carrier wave set is the set of the carrier wave that can be used for sending the first control information of the base station configuration, institute Stating the first control information is to send or receive the control information of the first data in the second carrier wave.

For example, the scheduling carrier wave collection for user device configuration is combined into carrier wave 1 (Cell-1), carrier wave 2 (Cell-2), carrier wave 3 (Cell-3), i.e., contain 3 carrier waves, respectively Cell-1, Cell-2 and Cell-3 in scheduling carrier wave set, this is only exchanged The citing for spending carrier set, is not the limitation of the quantity of the carrier wave contained to it or the carrier wave contained.Wherein, Cell-1 Carrier wave is the carrier wave on unshared frequency spectrum, and the carrier wave of Cell-2 and Cell-3 be the carrier wave shared on frequency spectrum.

The case where for carrying out the first data transmission using Cell-2 or receiving, base station send first to user equipment and refer to Show information.The first instruction information is used to indicate Cell-1 and Cell-2 as scheduling carrier wave set, i.e. scheduling carrier wave set Comprising Cell-1 and Cell-2, priority orders are Cell-1 > Cell-2.

The case where for carrying out the first data transmission using Cell-3 or receiving, base station send first to user equipment and refer to Show information.The first instruction information is used to indicate Cell-1, Cell-2, Cell-3 as scheduling carrier wave set, i.e. scheduling carries Wave set includes Cell-1, Cell-2 and Cell-3, and priority orders are Cell-2 > Cell-1 > Cell-3.

Step 63, the base station determines first carrier according to the first instruction information and preset condition.That is, the base station According to priority orders for belonging to each carrier wave of scheduling carrier wave set, each carrier wave for belonging to scheduling carrier wave set and pre- If condition determines first carrier.Specifically, base station can first belong to each carrier wave of scheduling carrier wave set and described according to The priority orders for belonging to each carrier wave of scheduling carrier wave set determine carrier wave undetermined according to sequence from high to low, then, institute It states base station and first carrier is determined according to the carrier wave undetermined and preset condition.Alternatively, base station can belong to scheduling load according to described Each carrier wave of wave set determines carrier wave undetermined, and then, the base station is according to the carrier wave undetermined, preset condition and described belongs to The priority orders of each carrier wave of scheduling carrier wave set determine first carrier.

Wherein, the first carrier is to meet in the carrier wave of the preset condition priority in the scheduling carrier wave set most High carrier wave, the first carrier are used for transmission the first control information.Optionally, the base station belongs to scheduling according to Each carrier wave of carrier set, the priority orders of each carrier wave for belonging to scheduling carrier wave set and preset condition determine One carrier wave.For example, base station successively judges according to the sequence from high to low for belonging to each carrier wave priority in scheduling carrier wave set Whether the carrier wave in the scheduling carrier wave set meets the preset condition, for example, base station first judges the scheduling carrier wave set Whether the carrier wave of middle highest priority meets the preset condition, and the carrier wave of highest priority is the carrier wave undetermined at this time, such as Fruit meets, then the carrier wave of the highest priority is the first carrier, if conditions are not met, then judging the scheduling carrier wave set In the preferential high carrier wave of level whether meet the preset condition, the high carrier wave of preferential level is the carrier wave undetermined at this time, such as Fruit meets, then the high carrier wave of the preferential level is the first carrier, if conditions are not met, according to priority from high to low suitable Sequence successively judges whether each carrier wave meets the preset condition.

Wherein, the preset condition includes at least one of the following conditions.Optionally, preset condition can be above-mentioned three Perhaps any two or preset condition are that following three conditions require to be satisfied for any one in a condition.Described In preset condition, the resource that the first control information is sent on the carrier wave undetermined refers to that the first control information exists The resource that can be occupied when being sent on the carrier wave undetermined.

Condition one: the carrier wave undetermined is that the carrier wave or the carrier wave undetermined on unshared frequency spectrum are on shared frequency spectrum Carrier wave and the carrier wave undetermined it is described first control information resource on it is in the open state.The open state is base station The result shared frequency spectrum monitored and listened to according to LBT rule is that the shared frequency spectrum is idle and the base station can be The shared frequency spectrum transmitting data.Otherwise, if the knot that base station is monitored and listened to shared frequency spectrum according to LBT rule Fruit is that the shared frequency spectrum is occupied, then the base station cannot be in the shared frequency spectrum transmitting data, the load undetermined described at this time Wave is in close state.

Condition two: the carrier wave undetermined is in discontinuous reception in the resource of the first control information The inactive phase of (Discontinuous Reception, DRX).Only in the inactive phase of discontinuous reception DRX, it is described to Determining the resource on carrier wave could be used to send control information, otherwise on the activation phase of discontinuous reception DRX, the carrier wave undetermined Resource cannot be used to send control information.

Condition three: the resource that the first control information is sent on the carrier wave undetermined belongs on the carrier wave undetermined in advance The resource for being used to send control information of configuration.The resource being pre-configured on the carrier wave undetermined can be in following resource at least It is a kind of:

(2) resource of the pre-configuration is the Physical Downlink Control Channel on the carrier wave undetermined on a certain downlink subframe The resource of (Physical Downlink Control Channel, PDCCH).Preceding 1~N of the i.e. described downlink subframe is (for being Regiment commander is wideN=3；For system bandwidthN=4) a OFDM symbol.The resource of the PDCCH is by described PCFICH channel notification on downlink subframe is to user equipment.The base station is sending first control according to the carrier wave undetermined Whether resource in the subframe of information processed is that resource in the PDCCH determines whether the carrier wave undetermined meets the default item Part.If it is, determining that the carrier wave undetermined meets the preset condition；If it is not, then determining that the carrier wave undetermined is unsatisfactory for The preset condition.For example, if sending the resource of the first control information on the carrier wave undetermined from N₁(N₁> 1) A OFDM symbol starts, then the resource that the first control information is sent on the carrier wave undetermined is not belonging to the carrier wave undetermined The resource for being used to send control information of upper pre-configuration, the carrier wave undetermined are unsatisfactory for the preset condition.If it is described to The resource for determining to send the first control information on carrier wave is then sent on the carrier wave undetermined since the 1st OFDM symbol It is described first control information resource belong to be pre-configured on the carrier wave undetermined for sends control information resource, it is described to Determine carrier wave and meets the preset condition.

Specifically as shown in fig. 7, Fig. 7 embodiment is by taking preset condition is while meeting condition one, condition two and condition three as an example It is illustrated, it should be understood that this is not the limitation to the embodiment of the present invention.

The case where for receiving or sending the first data using Cell-2:

In subframe n, since the carrier wave of Cell-2 is the carrier wave on shared frequency spectrum, base station is according to LBT rule to shared frequency spectrum Monitored and the 6th OFDM symbol listening in subframe n to start shared frequency spectrum idle, shared frequency spectrum can be occupied and send letter Number.Kth (k >=5) a OFDM symbol that the resource of the first control information of the first data is subframe n is sent in subframe n at this time Later resource.Base station described in the step determines first carrier according to the first instruction information and preset condition, specifically: root It is combined into Cell-1, Cell-2 according to scheduling carrier wave collection indicated by the first instruction information, priority orders are Cell-1 > Cell-2. Base station first determines whether the Cell-1 of highest priority meets preset condition.First condition and second condition are respectively " carrier wave undetermined be unshared frequency spectrum on carrier wave or the carrier wave undetermined be share frequency spectrum on carrier wave and it is described to It is in the open state in the resource of the first control information to determine carrier wave " and " carrier wave undetermined is in the first control letter The inactive phase of discontinuous reception (Discontinuous Reception, DRX) is in the resource of breath ", since Cell-1 is Carrier wave on unshared frequency spectrum meets first condition, is in the stage of DRX inactive phase in Cell-1, also meets second Condition.Third condition is that " resource that the first control information is sent on the carrier wave undetermined belongs to the carrier wave undetermined The resource for being used to send control information of upper pre-configuration ".Since Cell-1 is the carrier wave on unshared frequency spectrum, Cell-1 is upper prewired The resource set can be the PDCCH resource since the 1st OFDM symbol of the subframe, or a from subframe M (M < 4) The E-PDCCH resource that OFDM symbol starts.Resource due to sending the first control information of the first data in subframe n is subframe The later resource of kth (k >=5) a OFDM symbol of n, and the resource in PDCCH and E-PDCCH for sending control information is point It is not distributed in each OFDM symbol of the resource of PDCCH and E-PDCCH, therefore sends the first control letter on Cell-1 The opportunity of breath has already passed by, i.e., the first control information can be sent by having had already passed by k-th of OFDM symbol base station PDCCH resource or E-PDCCH resource.That is Cell-1 is unsatisfactory for third condition, cannot function as first carrier.Then basis Scheduling carrier wave collection indicated by first instruction information is combined into Cell-1, Cell-2, and priority orders are Cell-1 > Cell-2, base It stands and judges whether the high Cell-2 of preferential level meets preset condition again.First condition is that " carrier wave undetermined is unshared Carrier wave or the carrier wave undetermined on frequency spectrum are the carrier wave on shared frequency spectrum and the carrier wave undetermined is believed in first control It is in the open state in the resource of breath ", this is because Cell-2 can be accounted for since kth (k >=5) a OFDM symbol of subframe n Data are sent with shared channel, i.e., Cell-2 is in the open state since k-th of OFDM symbol, and therefore, Cell-2 meets the One condition.Second condition is that " carrier wave undetermined is in the resource of the first control information in discontinuous reception The inactive phase of (Discontinuous Reception, DRX) ".Meet the in the stage that Cell-2 is in the DRX inactive phase Two conditions." resource that the first control information is sent on the carrier wave undetermined belongs to the load undetermined to third condition What is be pre-configured on wave is used to send the resource of control information ".Since Cell-2 is the carrier wave on shared frequency spectrum, Cell-2 is upper prewired The resource for sending control information set, which can be the subframe, terminates preceding N₂(N₂≤ 3) resource of a OFDM symbol, therefore The resource for sending control information being pre-configured on Cell-2 can control information as sending described first on Cell-2 Resource.That is Cell-2 also meets third condition, therefore base station determines that Cell-2 is first carrier on subframe n.

In subframe n+1, since the carrier wave of Cell-2 is the carrier wave on shared frequency spectrum, base station is determined according to LBT rule in son Frame n+1 can occupy shared frequency spectrum and send signal.The resource of the first control information of the first data is sent in subframe n+1 at this time The 1st OFDM symbol for subframe n+1 starts or the 1st later resource of OFDM symbol.Base station described in the step is according to institute It states the first instruction information and preset condition determines first carrier, specifically: according to scheduling carrier wave indicated by the first instruction information Collection is combined into Cell-1, Cell-2, and priority orders are Cell-1 > Cell-2.Base station first determines whether the Cell-1 of highest priority Whether preset condition is met.First condition and second condition are that " carrier wave undetermined is the load on unshared frequency spectrum respectively Wave or the carrier wave undetermined are in the resource that the carrier wave on shared frequency spectrum and the carrier wave undetermined control information described first It is in the open state " and " carrier wave undetermined is in discontinuous reception in the resource of the first control information The inactive phase of (Discontinuous Reception, DRX) " meets since Cell-1 is the carrier wave on unshared frequency spectrum First condition is in the stage of DRX inactive phase in Cell-1, also meets second condition.Third condition is " described The resource that the first control information is sent on carrier wave undetermined belongs to the control that is used to send being pre-configured on the carrier wave undetermined and believes The resource of breath ".Since Cell-1 is the carrier wave on unshared frequency spectrum, the resource being pre-configured on Cell-1 be can be from the subframe The PDCCH resource that 1 OFDM symbol starts, or the E-PDCCH money since the subframe M (M < 4) a OFDM symbol Source.After the 1st OFDM symbol that resource due to sending the first control information of the first data in subframe n is subframe n+1 Resource, therefore be pre-configured on Cell-1 for sends control information resource can as on Cell-1 transmission described in The resource of first control information.That is Cell-1 meets third condition, can be used as first carrier.Therefore base station is determined in subframe The upper Cell-2 of n+1 is first carrier.

The case where for sending or receiving the first data using Cell-3, as shown in Figure 7:

In subframe n, since the carrier wave of Cell-3 is the carrier wave on shared frequency spectrum, base station determines subframe n's according to LBT rule 1st OFDM symbol starts the shared frequency spectrum free time, can occupy shared frequency spectrum and send signal.First is sent in subframe n at this time The 1st OFDM symbol that the resource of first control information of data is subframe n starts or the 1st later money of OFDM symbol Source.Here started using the resource for sending the first control information of the first data in subframe n as the 1st OFDM symbol of subframe n Resource for illustrate.Base station described in the step determines first carrier according to the first instruction information and preset condition, specifically Are as follows: Cell-1, Cell-2, Cell-3 are combined into according to scheduling carrier wave collection indicated by the first instruction information, priority orders are Cell-2 > Cell-1 > Cell-3.Base station first determines whether the Cell-2 of highest priority meets preset condition.First Condition be " carrier wave undetermined be unshared frequency spectrum on carrier wave or the carrier wave undetermined be share frequency spectrum on carrier wave and The carrier wave undetermined is in the open state in the resource of the first control information ", since Cell-2 is on shared frequency spectrum Carrier wave, base station cannot occupy the resource of shared frequency spectrum in the 1st OFDM symbol of subframe n according to LBT rule, Cell-2.Therefore, If the money that the 1st OFDM symbol that the resource for sending the first control information of the first data in subframe n is subframe n starts Source, since Cell-2 is in close state in the 1st OFDM symbol in subframe n, Cell-2 is unsatisfactory for first condition, It cannot function as first carrier.Then according to first instruction information indicated by scheduling carrier wave collection be combined into Cell-1, Cell-2, Cell-3, priority orders are Cell-2 > Cell-1 > Cell-3, and base station judges whether the high Cell-1 of preferential level is full again Sufficient preset condition.First condition and second condition be respectively " carrier wave undetermined be unshared frequency spectrum on carrier wave, or The carrier wave undetermined is the carrier wave on shared frequency spectrum and the carrier wave undetermined is in the resource of the first control information and opens Open state " and " carrier wave undetermined is in the resource of the first control information in discontinuous reception (Discontinuous Reception, DRX) the inactive phase ", since Cell-1 is the carrier wave on unshared frequency spectrum, meet first condition, Cell-1 is in the stage of DRX inactive phase, also meets second condition.Third condition is " to send out on the carrier wave undetermined The resource of the first control information is sent to belong to the resource for being used to send control information being pre-configured on the carrier wave undetermined ".By In the resource that the 1st OFDM symbol that the resource for the first control information for sending the first data in subframe n is subframe n starts. Since Cell-1 is the carrier wave on unshared frequency spectrum, the resource being pre-configured on Cell-1 be can be from the 1st OFDM symbol of the subframe Number PDCCH resource started, or the E-PDCCH resource since the subframe M (M < 4) a OFDM symbol.Due in son The resource that the 1st OFDM symbol that the resource that the first control information of the first data is sent in frame n is subframe n+1 starts, therefore, The resource for sending control information being pre-configured on Cell-1 can be believed as first control is sent on Cell-1 The resource of breath.That is Cell-1 meets third condition, can be used as first carrier.Therefore base station determines the Cell-1 on subframe n For first carrier.

In subframe n+1, since the carrier wave of Cell-3 is the carrier wave on shared frequency spectrum, base station is determined according to LBT rule in son Frame n+1 can occupy shared frequency spectrum and send signal.The resource of the first control information of the first data is sent in subframe n+1 at this time The 1st OFDM symbol for subframe n+1 starts or the 1st later resource of OFDM symbol.Here to send in subframe n Illustrate for the resource that the 1st OFDM symbol that the resource of first control information of one data is subframe n starts.Described in the step Base station determines first carrier according to the first instruction information and preset condition, specifically: according to indicated by the first instruction information Scheduling carrier wave collection be combined into Cell-1, Cell-2, Cell-3, priority orders are Cell-2 > Cell-1 > Cell-3.Base station First determine whether the Cell-2 of highest priority meets preset condition.First condition is that " carrier wave undetermined is unshared Carrier wave or the carrier wave undetermined on frequency spectrum are the carrier wave on shared frequency spectrum and the carrier wave undetermined is believed in first control It is in the open state in the resource of breath ", since Cell-2 is the carrier wave on shared frequency spectrum, base station exists according to LBT rule, Cell-2 The 1st OFDM symbol of subframe n can occupy the resource of shared frequency spectrum.Therefore, if sending the of the first data in subframe n The resource that the 1st OFDM symbol that the resource of one control information is subframe n starts, Cell-2 is in the 1st OFDM symbol in subframe n It is number in the open state, therefore Cell-2 meets first condition.Second condition is that " carrier wave undetermined is in first control The inactive phase of discontinuous reception (Discontinuous Reception, DRX) is in the resource of information processed ", in Cell-2 Stage in the DRX inactive phase also meets second condition.It " is sent out on the carrier wave undetermined finally, for third condition The resource of the first control information is sent to belong to the resource for being used to send control information being pre-configured on the carrier wave undetermined ", by In the resource that the 1st OFDM symbol that the resource for the first control information for sending the first data in subframe n is subframe n starts. Since Cell-2 is the carrier wave on shared frequency spectrum, the resource for sending control information being pre-configured on Cell-2 can be the son N before frame end₂(N₂≤ 3) resource of a OFDM symbol, therefore, what is be pre-configured on Cell-2 is used to send the money of control information Source can be used as the resource that the first control information is sent on Cell-2.That is Cell-2 meets third condition, therefore base It stands and determines that Cell-2 is first carrier on subframe n.

Step 64, the user equipment determines first carrier according to the first instruction information and preset condition.That is, user Equipment is according to belonging to each carrier wave of scheduling carrier wave set, the priority orders of each carrier wave for belonging to scheduling carrier wave set First carrier is determined with preset condition.Specifically, the user equipment belongs to each of scheduling carrier wave set according to first The priority orders of carrier wave and each carrier wave for belonging to scheduling carrier wave set determine load undetermined according to sequence from high to low Wave, then, the user equipment determine first carrier according to the carrier wave undetermined and preset condition.Alternatively, the user equipment The each carrier wave for belonging to scheduling carrier wave set according to first determines carrier wave undetermined, and then, the user equipment is according to The priority orders of carrier wave undetermined, preset condition and each carrier wave for belonging to scheduling carrier wave set determine first carrier.

Wherein, the first carrier is to meet in the carrier wave of the preset condition priority in the scheduling carrier wave set most High carrier wave, the first carrier are used for transmission the first control information.Optionally, the user belongs to scheduling according to described Each carrier wave of carrier set, the priority orders of each carrier wave for belonging to scheduling carrier wave set and preset condition determine One carrier wave.For example, user equipment is according to belonging to the sequence from high to low of each carrier wave priority in scheduling carrier wave set successively Judge whether the carrier wave in the scheduling carrier wave set meets the preset condition, for example, user equipment first judges the scheduling Whether the carrier wave of highest priority meets the preset condition in carrier set, and the carrier wave of highest priority is described undetermined at this time Carrier wave, if it is satisfied, then the carrier wave of the highest priority is the first carrier, if conditions are not met, then judging the scheduling Whether the high carrier wave of preferential level meets the preset condition in carrier set, and the high carrier wave of preferential level is described undetermined at this time Carrier wave, if it is satisfied, then the high carrier wave of the preferential level is the first carrier, if conditions are not met, according to priority by height Successively judge whether each carrier wave meets the preset condition to low sequence.

Condition one: the carrier wave undetermined is that the carrier wave or the carrier wave undetermined on unshared frequency spectrum are on shared frequency spectrum Carrier wave and the carrier wave undetermined it is described first control information resource on it is in the open state.The user equipment is according to base The base station is in the open state on the shared frequency spectrum or the instruction information that is in close state is true for being used to indicate of standing The fixed carrier wave undetermined is in the open state or is in close state.Or the user equipment is according to preset specific letter Number or the detection of preset particular channel determine that the carrier wave undetermined is in the open state or closed state.

Condition two: the carrier wave undetermined is in discontinuous reception in the resource of the first control information The inactive phase of (Discontinuous Reception, DRX).The user equipment is matched according to the DRX's of the carrier wave undetermined Set the timer that parameter and dispatch situation, data transmission scenarios of the base station to the user equipment determine the related each timer of DRX State determines that the carrier wave undetermined is in the inactive phase of DRX or the activation phase in DRX.

(1) resource of the pre-configuration is the downlink subframe in the carrier wave undetermined or the resource during downlink transfer.Institute State user equipment according to the carrier wave undetermined send it is described first control information subframe whether be downlink subframe or be under Resource during row transmission, determines whether the carrier wave undetermined meets the preset condition.If it is, determining the load undetermined Wave meets the preset condition；If it is not, then determining that the carrier wave undetermined is unsatisfactory for the preset condition.The user equipment root According to base station send third instruction information determine the carrier wave undetermined send it is described first control information subframe whether be under Row subframe is the resource during downlink transfer, wherein the third instruction information is used to indicate on the shared frequency spectrum Send it is described first control information subframe be the subframe type of downlink subframe or sub-frame of uplink or be uplink during Resource or be the resource during downlink transfer.

Alternatively, the user equipment according to the detection to preset signal specific or preset particular channel determine it is described to Determine resource of the carrier wave during whether the subframe for sending the first control information is downlink subframe or is downlink transfer.

(2) resource of the pre-configuration is the Physical Downlink Control Channel on the carrier wave undetermined on a certain downlink subframe The resource of (Physical Downlink Control Channel, PDCCH).Preceding 1~N of the i.e. described downlink subframe is (for being Regiment commander is wideN=3；For system bandwidthN=4) a OFDM symbol.The resource of the PDCCH is by described PCFICH channel notification on downlink subframe is to user equipment.The user equipment is sending described the according to the carrier wave undetermined It is described pre- whether resource in the subframe of one control information is that resource in the PDCCH determines whether the carrier wave undetermined meets If condition.If it is, determining that the carrier wave undetermined meets the preset condition；If it is not, then determining the carrier wave undetermined not Meet the preset condition.For example, if sending the resource of the first control information on the carrier wave undetermined from N₁(N₁ > 1) a OFDM symbol starts, then sent on the carrier wave undetermined the first control information resource be not belonging to it is described undetermined What is be pre-configured on carrier wave is used to send the resource of control information, and the carrier wave undetermined is unsatisfactory for the preset condition.If institute Resource that the first control information is sent on carrier wave undetermined of stating is since the 1st OFDM symbol, then on the carrier wave undetermined The resource for sending the first control information belongs to the resource for being used to send control information being pre-configured on the carrier wave undetermined, institute It states carrier wave undetermined and meets the preset condition.

(3) resource of the pre-configuration be the base station be receive it is described first control information user device configuration Physical Downlink Control Channel (the Enhanced Physical Downlink Control of enhancing on the carrier wave undetermined Channel, E-PDCCH) resource.Initial position of the E-PDCCH resource in a subframe in time domain by PCFICH or Person is notified by high-level signaling to the user equipment, frequency domain of the E-PDCCH resource in a subframe by the base station Position is notified by high-level signaling to the user equipment by the base station.The user equipment is being sent out according to the carrier wave undetermined Send whether the resource in the subframe of the first control information is whether resource in the E-PDCCH determines the carrier wave undetermined Meet the preset condition.If it is, determining that the carrier wave undetermined meets the preset condition；If it is not, then described in determining Carrier wave undetermined is unsatisfactory for the preset condition.For example, if the resource for the E-PDCCH being pre-configured on the carrier wave undetermined is from 3 OFDM symbols start, and the transmission described first controls the resource of information since M (M > 3) a OFDM symbol, then Send that the resource of the first control information is not belonging to be pre-configured on the carrier wave undetermined on the carrier wave undetermined for sending out The resource of control information is sent, the carrier wave undetermined is unsatisfactory for the preset condition.If described in being sent on the carrier wave undetermined The resource of first control information then sends the first control information since the 3rd OFDM symbol on the carrier wave undetermined Resource belong to be pre-configured on the carrier wave undetermined for sends control information resource, the carrier wave undetermined meets described pre- If condition.

The case where specifically as shown in fig. 7, for sending or receiving the first data using Cell-2:

In subframe n, since the carrier wave of Cell-2 is the carrier wave on shared frequency spectrum, user equipment is used to indicate according to base station The base station is in the open state on the shared frequency spectrum or the instruction information that is in close state determines the load undetermined Wave is in the open state or is in close state.Or the user equipment is according to preset signal specific or preset spy The detection for determining channel determines that the carrier wave undetermined is in the open state or closed state.Instruction or user by the base station The detection of equipment determines that base station starts that shared frequency spectrum transmission signal can be occupied in the 6th OFDM symbol of subframe n.At this time in son The later resource of kth (k >=5) a OFDM symbol that the resource that the first control information of the first data is sent in frame n is subframe n. User equipment described in the step determines first carrier according to the first instruction information and preset condition, specifically: according to first Scheduling carrier wave collection indicated by instruction information is combined into Cell-1, Cell-2, and priority orders are Cell-1 > Cell-2.User sets It is standby to first determine whether the Cell-1 of highest priority meets preset condition.First condition and second condition are " institute respectively State carrier wave undetermined be unshared frequency spectrum on carrier wave or the carrier wave undetermined be share frequency spectrum on carrier wave and the load undetermined Wave is in the open state in the resource of the first control information, " and " carrier wave undetermined is in the first control information The inactive phase of discontinuous reception (Discontinuous Reception, DRX) is in resource ", since Cell-1 is non-total The carrier wave on frequency spectrum is enjoyed, first condition is met, is in the stage of DRX inactive phase in Cell-1, also meets second condition.
