Below in conjunction with the accompanying drawings of the present invention in embodiments, the technical solutions in the embodiments of the present invention are clearly and completely described, obviously, the described embodiments are merely part of embodiments of the present invention rather than all embodiments. Based on the embodiments of the present invention, all other embodiments of ordinary skill in the art without any creative effort shall fall within the scope of the present invention.

First, a brief prior art base station (eNB) how the spectrum resource scheduling and resource scheduling process spectrum problems. A base station may create a plurality of cells. Suppose a base station uses unlicensed spectrum to create a cell A, authorizing the use of language to create a community-frequency B. Sent to the uplink resource needed by the buffer status report (BSR, Buffer S ta te Repor t) When cell A and cell B in a user equipment (UE, User Equ i pment) To the base station when transmitting data, the data needs to be sent the base station, then according to a buffer status report for the user equipment allocation of spectrum resources. Because the unlicensed spectrum resources the user equipment is shared with other system resources, user equipment needs to get competitive with other systems to unlicensed spectrum resources, and the user equipment can be competitive to the unlicensed spectrum resources is uncertain, and therefore the base station does not allocate the spectrum resources to the user equipment unauthorized, corresponding, where spectrum resources for scheduling of the base station mainly refers licensed spectrum resources.

Wherein the cell Β created using licensed spectrum cell, the cell can Β user equipment for data transmission using the licensed spectrum. The base station resource scheduling for a user equipment belonging to the prior art cell Β and are not repeated here.

The base station while user equipment buffer status report is transmitted from the cell A cell Α user equipment resource scheduling, since the cell A is a cell using an unlicensed frequency created by language, then the user equipment will be competitive to the cell A Some unlicensed spectrum resources and use these unlicensed spectrum for data transmission. If the buffer status report is required when all the resources the user equipment transmits data cell A, when the base station a buffer status report using the cell A as an authorized user equipment allocation of spectrum resources licensed spectrum resource allocation would exceed the cell A user the actual resources needed equipment, resulting in over-scheduling resources. Object of the present invention is to solve the problem.

Note that, actually in the buffer status report is Byte data to be transmitted to the user equipment (octets) or bi t (bit) number, and the base station is required for a user equipment buffer status report according to the amount of data in resource scheduling, i.e. scheduling of the base station is a user equipment byte data to be transmitted (in bytes) or the number of bi t (bit) corresponding to the number of spectrum resources.

1, in order to solve the above problems, according to a first embodiment of the present invention, a spectrum resource scheduling means located in user equipment, comprising: an acquisition unit 11 for acquiring unlicensed spectrum resources to competitive; determining means 12, connected to the acquisition unit 11, for uplink transmission according to the resource acquisition unit 11 acquires competitive unlicensed spectrum to determine needed resources; transmission unit 13 connected to the determination unit 12, for determining the transmission of the uplink transmission resource unit 12 determines required for scheduling resources to a base station to request the base station for scheduling resources according to the resource scheduling uplink transmission resources needed.

Wherein the rear, the acquiring unit 11 acquires the user equipment to the competitive unlicensed spectrum resources, according to modulation and coding scheme used on the unlicensed spectrum, to determine the competitive unlicensed spectrum can be transmitted The amount of data.

Wherein the acquisition unit 12 also acquires the amount of data to be transmitted for the current buffer and acquiring the amount of data that can be transmitted on the basis of the competitive unlicensed spectrum to unlicensed spectrum resources; the determining unit 12 is specifically for the acquisition unit 11 acquires the amount of data to be transmitted in the current buffer amount of the difference data can be transferred to the unlicensed spectrum as the uplink transmission resource needs.

Wherein the transmission unit 13 is further configured to: when the uplink transmission resource required is greater than or equal to a first predetermined value greater than the transmission of the uplink transmission resource required for scheduling resources to the base station. In particular applications, the first predetermined value may be set depending on the circumstances, as may be set to 0, may be set to another value, which is not defined. That is, in practical applications, regardless of whether the uplink transmission resource is the number required, the transmission unit 13 may need to send uplink transmission resource to the base station for scheduling resources; or uplink transmission resource only when needed is greater than or when not less than a certain value (first predetermined value), the transmission unit 13 will require uplink transmission resource to the base station for scheduling of resources, in this case, the base station for scheduling resources for a user equipment not spectrum resource scheduling, then the user device may continue with other competitive devices unlicensed spectrum resources, the unauthorized use of competitive frequency transmission data.

In a practical application, the base station for scheduling a resource may be one, or may be a plurality. The following are the base station for scheduling and resource for a plurality of (in the example, two) base stations of the spectrum resource scheduling process is described in both cases.

(1) when the base station for scheduling a resource only (assuming as eNB), the transmission unit 13 is specifically configured to: uplink transmission resources required for transmission to the buffer status report scheduling resources a base station, to request the base station according to the uplink transmission resource scheduling resources required for performing the resource scheduling. In a practical application, the user equipment may report the buffer status report to the base station through the cell (Unl icensed Cel l, referred to as U-Cel l) on the unlicensed spectrum, or by a cell on a frequency authorized language 4 ( L i cens ed Ce 11, the buffer status report referred to L-Ce 11) will be reported to the base station.

(2) when the base station for scheduling resources when there are two, comprising a primary base station is assumed (the MeNB) and a secondary base station (the SeNB), at this time the sending unit 13 is configured to: transmit the uplink resources required by transmitting a buffer status report to the secondary base station (SeNB), then the secondary base station (the SeNB) buffer status report to the primary base station (MeNB), the primary base station to request an uplink according to the desired transmission resource for resource scheduling; or uplink transmission resources required sent directly to the main base station (the MeNB) through a buffer status report to request the primary base station performs resource scheduling uplink transmission resources according to the needs.

Further, the user equipment (UE) in competition to the unlicensed spectrum available resources after the competition to unlicensed spectrum resources for transmitting data (step 123a) to the secondary base station (eNB). Thus unlicensed spectrum, the sending unit 13 for further competition by the acquisition unit 11 acquires data to transmit to the secondary station. Unlicensed spectrum, of course, if the base station for scheduling of resources is only one, the transmission unit 13 for competition with the acquiring unit 11 acquires the base station to schedule the resource for a (FIG. 2 base station eNB) transmits data.

As can be seen, the spectrum resource scheduling device according to one embodiment of the present invention, in the use of unlicensed spectrum to create a cell, considering that the user equipment can utilize competitive unlicensed spectrum resources to transmit a part of data. While the prior art does not take this into account, scheduling of resources for the base station or the entire amount of data transmitted by the user equipment is currently to be cached for the user equipment allocation of spectrum resources, so that the base station allocates transmission resources to the uplink user equipment It exceeds the uplink transmission resource the user equipment actually needed. Thus compared with the prior art, for example, a spectrum of spectral resource scheduling resource scheduling apparatus according to a first possible solution, when only one base station for scheduling resources shown in Figure 2, embodiments of the present invention, the present invention for:

Step 111, the user equipment (UE) and other competitive systems using unlicensed spectrum resources.

Step 112, the user equipment (UE) to obtain competition unlicensed spectrum resources, determining the amount of data can be transmitted on to the competitive unlicensed spectrum, and trigger buffer status report.

Step 113, the user equipment (UE) to the amount of data to be transmitted to the cache of the current difference of the unlicensed spectrum of data that can be transmitted on a resource of the uplink transmission resource as needed, and the resources to cache status report (BSR) in the form of reports to the base station (eNB) for scheduling resources. Alternatively, the user equipment (UE) may only be greater than or equal to greater than a certain threshold value when the transmission buffer status report (BSR) to the base station for scheduling uplink transmission resources in the resources required.

Step 114, the base station (eNB) for scheduling resources for the user equipment determines whether the licensed spectrum allocated resources, i.e., to determine whether the licensed spectrum in the cell (L-Cel l) to the user equipment resource scheduling.

The base station (eNB) in particular, said means for scheduling uplink resources may be needed to determine the user equipment (UE) in a licensed spectrum allocated according to uplink transmission resource (buffer status value) of the user equipment buffer status report required transmission resources (ie uplink grant). Or the base station for scheduling a resource may be the only cache state value is larger than a certain threshold, the user equipment before allocating licensed spectrum resources, otherwise, the user equipment is not allocated licensed spectrum allocation resources.

Step 115, when the base station (eNB) determines the scheduling of resources for the user equipment (UE) allocated licensed spectrum resources, transmitting a physical downlink control channel (PDCCH, Phys ica l Downl to the user equipment (UE) ink Cont rol Channel) scheduling signaling, uplink transmission resource indication of the user equipment (UE) may be used in a licensed spectrum, after the user equipment can use the licensed spectrum allocated resources to the base station (eNB) data .

Further, the user equipment (UE) after the competition to the unlicensed spectrum using the resources can be competitive to the unlicensed spectrum resource data to the base station (eNB) transmits, i.e., at step 113, the user equipment ( UE) to the base station further data (eNB) transmits to competition with the unlicensed spectrum.

3, when the base station has two resource for scheduling when, for example, a spectrum resource scheduling procedure is the embodiment of the present invention:

Step 121, the user equipment (UE) and other competitive systems using unlicensed spectrum resources.

Step 122, the user equipment (UE) to obtain competition unlicensed spectrum resources, determining the amount of data can be transmitted on to the competitive unlicensed spectrum, and trigger buffer status report.

Step 123b, the user equipment (UE) to the amount of data to be transmitted to the cache of the current difference of the unlicensed spectrum of data that can be transmitted on a resource of the uplink transmission resource as needed, and the resources to cache status report (BSR) reporting to the form of the secondary base station (SeNB), then the secondary base station (the SeNB) buffer status report (BSR) reporting to the main base station (the MeNB); or the buffer status report (BSR) reporting directly to the main base station (MeNB). The course, user equipment (UE) may be provided only in the uplink transmission resource required is greater than or equal to a threshold value greater than the buffer status report (BSR) by the secondary base station (the SeNB) to the main base station (the MeNB) report or reports directly to the main base station (MeNB).

Step 124, the main base station (the MeNB) determining whether the user equipment is authorized to allocate spectrum resources, i.e., to determine whether the licensed spectrum in the cell (L-Cell) to the user equipment resource scheduling. Specifically, with reference to the embodiment of the scheduling process may be a base station (eNB) by using a buffer status report resource scheduling of the process, it is not repeated here.

Step 125, when the master station (the MeNB) is determined for the user equipment (UE) allocated licensed spectrum resources, transmitting a physical downlink control channel (PDCCH, Physical Downlink Control Channel) scheduling signaling to the user equipment (UE) , uplink transmission resource indication of the user equipment (UE) may be used in the licensed spectrum. After the user equipment (UE) can use the allocated resources licensed spectrum transmitting data to the primary base station (MeNB).

Wherein, the first scheduling unit 22 is specifically configured to: according to the uplink transmission resources required for the user equipment allocation grant spectrum resources; or greater than or equal to a second predetermined value greater than the uplink transmission resources when required, for the user equipment allocation grants spectrum resources. The second predetermined value may be set according to specific circumstances, such as 0 may be provided, may also be set to other values, which is not defined. In the case where the base station for scheduling a resource to only one base station, the first acquisition unit

21 is specifically configured to: obtain an uplink transmission resource the user equipment by transmitting a buffer status report required. At this time, the first specific resource scheduling process scheduling unit 22 may refer to procedure 2 described in FIG resource scheduling, not described herein again.

In the case of the base station for scheduling resources comprises a primary station and a secondary station, the primary base station located in said first acquiring unit 21, the first obtaining unit 21 is specifically configured to: through the secondary base station of the uplink transmission resources required by the user equipment buffer status report, of course, may acquire the uplink transmission resource sent by the user equipment buffer status report needs directly from the user equipment. Further, the secondary station may be used for unauthorized use of the user equipment receiving competitive spectral data to be transmitted. At this time, the first specific resource scheduling process scheduling unit 22 may be described with reference to FIG. 3, the resource scheduling procedure, and are not repeated here.

Note that, in the case where the base station for scheduling resources only one base station, the apparatus of the first obtaining unit 21 is located in a base station, for receiving the user equipment to utilize unlicensed competitive language frequency data sent.

It can be seen from the spectrum resource scheduling apparatus according to a second embodiment of the present invention, in the use of unlicensed spectrum to create a cell, considering that the user equipment can utilize competitive unlicensed spectrum resources to transmit a part of data. While the prior art does not take this into account, scheduling of resources for the base station or the entire amount of data transmitted by the user equipment is currently to be cached for the user equipment allocation of spectrum resources, so that the base station allocates transmission resources to the uplink user equipment It exceeds the uplink transmission resource the user equipment actually needed. As compared with the prior art, the present invention is spectral resource scheduling apparatus according to a second uplink transmission resource can be solved when an unauthorized user device spectral data transmission through scheduling problem embodiment.

When the base station for scheduling resources comprises the primary station and a secondary station, this step is specifically: the need to report uplink transmission resource transmitted by said master station buffer status of the user equipment acquired by the secondary base station, i.e., the first user device transmits the buffer status report to the secondary base station, then the secondary station forwarding the buffer status report to the host station. Of course, the primary base station may also obtain an uplink transmission resource the user equipment buffer status report transmitted by the need directly from the user equipment.

Step 42, the spectrum resource scheduling the uplink transmission resource utilization needs.

This step is specifically: The uplink transmission resources required for the user equipment allocation grant spectrum resources; or when the uplink transmission resource required is greater than or equal to a second predetermined value greater than, the user equipment spectrum allocation grants resources.

Wherein the specific embodiments of the method may be implemented using a device of the invention according to embodiment II, which is not repeated herein.
