Due to the increasing demand for mobile broadband, the current licensed spectrum cannot fully meet the needs of users.

At present, the band utilization rate of unlicensed spectrum is relatively low, so more and more mobile operators hope to use the unlicensed spectrum to provide communication services for users. For example, a base station creates a cell using an unlicensed spectrum. If the spectrum resource is used to transmit data to the base station, the user equipment reports the uplink transmission resource required for the data transmission to the base station. The base station determines the uplink transmission resource that needs to be allocated for the user equipment according to the content reported by the user equipment.

When a cell is created by using an unlicensed spectrum, the user equipment can compete for resources with other user equipments on the unlicensed spectrum, and use the contending resources for data transmission. Therefore, if the base station still uses the user in the manner of the prior art When the device allocates resources, the uplink transmission resource allocated by the base station to the user equipment exceeds the uplink transmission resource actually needed by the user equipment, and the over-scheduling problem of the uplink transmission resource occurs.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

First, briefly introduce how the base station (eNB) in the prior art schedules spectrum resources and the problems in the spectrum resource scheduling process. A base station can create multiple cells. Suppose a base station creates a cell A with an unlicensed spectrum and creates a cell B with an authorized frequency. When the user equipment (UE, User Equ i pment) of the cell A and the cell B needs to send data to the base station, the uplink resource required for transmitting data needs to be sent to the buffer status report (BSR, Buffer S ta te Repor t). The base station, the base station allocates spectrum resources to the user equipment according to the buffer status report. Because the unlicensed spectrum resource is a resource shared by the user equipment and other systems, the user equipment needs to compete with other systems to obtain unlicensed spectrum resources, and the amount of unlicensed spectrum resources that the user equipment can compete for is uncertain. The base station cannot allocate unlicensed spectrum resources to the user equipment. It should be noted that the spectrum resources used by the base station for scheduling mainly refer to the licensed spectrum resources.

The cell Β is a cell created by using the licensed spectrum, and the user equipment of the cell 只能 can only use the licensed spectrum for data transmission. It is a prior art that the base station performs resource scheduling for the user equipment of the cell ,, and details are not described herein again.

The base station performs resource scheduling for the user equipment of the cell A according to the buffer status report sent by the user equipment of the cell, and the cell A is a cell created by using the unlicensed frequency. Some unlicensed spectrum resources, and use these unlicensed spectrum for data transmission. If the buffer status report is all the resources required for the user equipment of the cell A to send data, when the base station allocates the licensed spectrum resource to the user equipment of the cell A by using the buffer status report, the allocated authorized spectrum resource exceeds the user of the cell A. The resources actually needed by the device, resulting in over-scheduling of resources. The object of the present invention is to solve this problem.

It should be noted that in the cache status report, the number of Bytes (bytes) or bit (bits) of data that the user equipment needs to transmit is actually required, and the base station needs to perform the user equipment according to the amount of data in the buffer status report. Resource scheduling, that is, the base station schedules spectrum resources corresponding to the number of Bytes (bytes) or bit (bits) of data that the user equipment needs to transmit.

As shown in FIG. 1 , in order to solve the above problem, the first embodiment of the present invention provides a spectrum resource scheduling apparatus, which is located in a user equipment, and includes: an acquiring unit 11 , configured to acquire a competitive unlicensed spectrum resource; And the obtaining unit 11 is configured to determine, according to the unlicensed spectrum resource that is obtained by the acquiring unit 11, the required uplink transmission resource; the sending unit 13 is connected to the determining unit 12, and is configured to The required uplink transmission resource determined by the determining unit 12 is sent to a base station for scheduling resources, to request the base station for scheduling resources to perform resource scheduling according to the required uplink transmission resource.

After acquiring the unlicensed spectrum resource that the user equipment competes, the acquiring unit 11 may determine, according to the modulation and coding mode used on the unlicensed spectrum, that the unlicensed spectrum that is competitive can be transmitted. The amount of data.

The obtaining unit 12 is further configured to acquire the currently buffered data volume to be sent and according to Obtaining the amount of data that can be transmitted on the unlicensed spectrum; the determining unit 12 is specifically configured to use the current cached data volume to be sent acquired by the acquiring unit 11 and the The difference in the amount of data that can be transmitted on the unlicensed spectrum is used as the required uplink transmission resource.

The sending unit 13 is further configured to: when the required uplink transmission resource is greater than or equal to a first predetermined value, send the required uplink transmission resource to a base station used for scheduling resources. In a specific application, the first predetermined value may be set according to a specific situation, and may be set to 0, and may be set to other values, which is not limited herein. That is, in an actual application, regardless of the required uplink transmission resources, the sending unit 13 may send the required uplink transmission resources to the base station for scheduling resources; or only when the required uplink transmission resources are greater than or When the value is greater than or equal to a certain value (the first predetermined value), the sending unit 13 sends the required uplink transmission resource to the base station for scheduling the resource. In this case, the base station for scheduling the resource is not the user equipment. The spectrum resource is scheduled. At this time, the user equipment can continue to compete with other devices for unlicensed spectrum resources, and use the unlicensed frequency to transmit the data.

In practical applications, the base station used for scheduling resources may be one or multiple. The following describes the scheduling process of the spectrum resources by the base station in the case where the base station for scheduling resources is one or more (for example, two).

(1) When the base station for scheduling resources has only one (assumed to be an eNB), the sending unit 13 is specifically configured to: send the required uplink transmission resource to the scheduling resource by using a buffer status report. The base station requests the base station for scheduling resources to perform resource scheduling according to the required uplink transmission resource. In a practical application, the user equipment may report the buffer status report to the base station through a cell on the unlicensed spectrum (U-Cel l for short), or may pass the cell on the 4 authorized frequency ( L i cens ed Ce 11 (L-Ce 11 for short) reports the buffer status report to the base station.

(2) When there are two base stations for scheduling resources, assuming that a primary base station (MeNB) and a secondary base station (SeNB) are included, the sending unit 13 is specifically configured to: use the required uplink transmission resource The source is sent to the secondary base station (SeNB) by using a buffer status report, and the secondary base station (SeNB) sends the buffer status report to the primary base station (MeNB) to request the primary base station to perform according to the required The uplink transmission resource is used for resource scheduling; or the required uplink transmission resource is directly sent to the primary base station (MeNB) through the buffer status report, to request the primary base station to perform resource scheduling according to the required uplink transmission resource.

In addition, the user equipment (UE) may use the unlicensed spectrum resources that are derived to transmit data to the secondary base station (eNB) after competing for unlicensed spectrum resources (step 123a). Therefore, the sending unit 13 is further configured to send data to the secondary base station by using the competitive unlicensed spectrum acquired by the acquiring unit 11. Of course, if there is only one base station for scheduling resources, the sending unit 13 is configured to use the unlicensed spectrum acquired by the acquiring unit 11 to the base station for scheduling resources (as shown in the figure). The base station eNB in 2 transmits data.

As can be seen from the above, the spectrum resource scheduling apparatus according to the first embodiment of the present invention considers that the user equipment can transmit a part of the data by using the unlicensed spectrum resources that are competitive when the cell is created by using the unlicensed spectrum. The prior art does not take this into consideration. The base station for scheduling resources allocates spectrum resources to the user equipment according to the total amount of data to be sent currently buffered by the user equipment, so that the base station allocates uplink transmission resources to the user equipment. The uplink transmission resources actually needed by the user equipment are exceeded. Therefore, compared with the prior art, the spectrum resource scheduling apparatus provided in Embodiment 1 of the present invention can solve the spectrum resource scheduling process in Embodiment 1 of the present invention when the base station for scheduling resources has only one, as shown in FIG. 2 . For:

Step 111: The user equipment (UE) competes with other systems that use the unlicensed spectrum for resources.

Step 112: The user equipment (UE) obtains the unlicensed spectrum resource that is competitive, determines the amount of data that can be transmitted on the unlicensed spectrum that is contending, and triggers the buffer status report.

Step 11: The user equipment (UE) uses the difference between the currently buffered data volume to be transmitted on the unlicensed spectrum resource as the required uplink transmission resource, and caches the resource. The status report (BSR) is reported to the base station (eNB) for scheduling resources. or, The user equipment (UE) may also send a buffer status report (BSR) to the base station for scheduling resources only when the required uplink transmission resource is greater than or equal to a certain threshold.

Step 114: The base station (eNB) for scheduling resources determines whether to allocate the authorized spectrum resource to the user equipment, that is, whether the cell (L-Cel l) on the licensed spectrum performs resource scheduling for the user equipment.

Specifically, the base station (eNB) for scheduling resources may determine, according to the uplink transmission resource (cache status value) required by the user equipment in the buffer status report, that the user equipment (UE) needs to be allocated on the authorized spectrum. Transmission resources (ie, uplink grants). Or the base station for scheduling the resource may allocate the licensed spectrum resource to the user equipment only when the buffer status value is greater than a certain threshold. Otherwise, the user equipment is not allocated the authorized spectrum. Resources.

Step 115: When the base station (eNB) for scheduling resources determines to allocate the licensed spectrum resource to the user equipment (UE), send a physical downlink control channel (PDCCH, Phys ica l Downl) to the user equipment (UE). Ink Cont rol Channel), indicating that the user equipment (UE) can use uplink transmission resources on the licensed spectrum, and then the user equipment can use the allocated licensed spectrum resource to send data to the base station (eNB) .

In addition, the user equipment (UE) may use the unlicensed spectrum resource that is competitive to transmit data to the base station (eNB) after competing for the unlicensed spectrum resource, that is, in step 113, the user equipment ( The UE may also transmit data to the base station (eNB) by using the unlicensed spectrum resources that are derived.

As shown in FIG. 3, when there are two base stations for scheduling resources, the spectrum resource scheduling process in the first embodiment of the present invention is:

Step 121: The user equipment (UE) competes with other systems that use the unlicensed spectrum for resources.

Step 122: The user equipment (UE) obtains the unlicensed spectrum resource that is competitive, determines the amount of data that can be transmitted on the unlicensed spectrum that is contending, and triggers the buffer status report.

Step 123b: The user equipment (UE) uses, as the uplink transmission resource, the difference between the currently buffered data volume to be transmitted and the data amount that can be transmitted on the unlicensed spectrum resource, and The resource is reported to the secondary base station (SeNB) in the form of a buffer status report (BSR), and the secondary base station (SeNB) reports the buffer status report (BSR) to the primary base station (MeNB); or The buffer status report (BSR) is directly reported to the primary base station (MeNB). Of course, the user equipment (UE) may also send the buffer status report (BSR) to the primary base station through the secondary base station (SeNB) only when the required uplink transmission resource is greater than or equal to a certain threshold. (MeNB) reports or directly reports to the primary base station (MeNB).

Step 124: The primary base station (MeNB) determines whether to allocate the licensed spectrum resource to the user equipment, that is, whether the cell (L-Cell) on the licensed spectrum performs resource scheduling for the user equipment. For the specific scheduling process, reference may be made to the process of the resource scheduling by the base station (eNB) in the foregoing example by using the buffer status report, and details are not described herein again.

Step 125: When the primary base station (MeNB) determines to allocate the licensed spectrum resource to the user equipment (UE), send a physical downlink control channel (PDCCH, Physical Downlink Control Channel) scheduling signaling to the user equipment (UE). And indicating an uplink transmission resource that the user equipment (UE) can use on the licensed spectrum. The user equipment (UE) can then transmit data to the primary base station (MeNB) using the allocated licensed spectrum resources.

As shown in FIG. 4, the second embodiment of the present invention provides a spectrum resource scheduling apparatus, which is located in a base station for scheduling resources, and includes: a first acquiring unit 21, configured to acquire required uplink transmission resources determined by user equipments. The first scheduling unit 22 is connected to the first acquiring unit 21, and is configured to schedule the spectrum resource by using the required uplink transmission resource acquired by the first acquiring unit 21; The required uplink transmission resource obtained by the user equipment 21 is determined by the user equipment according to the unlicensed spectrum resource that is obtained.

The second predetermined value may be set according to a specific situation, and may be set to 0, and may be set to other values, which is not limited herein. In the case that the base station for scheduling resources has only one base station, the first acquiring unit

The method is specifically configured to: obtain the required uplink transmission resource that is sent by the user equipment by using a buffer status report. At this time, the specific resource scheduling process of the first scheduling unit 22 may refer to the description of the resource scheduling process in FIG. 2, and details are not described herein again.

In addition, the secondary base station may be configured to receive data that is sent by the user equipment by using the unlicensed spectrum that is contending. At this time, the specific resource scheduling process of the first scheduling unit 22 may refer to the description of the resource scheduling process in FIG. 3, and details are not described herein again.

It should be noted that, in the case that the base station for scheduling resources has only one base station, the first acquiring unit 21 in the device is located in the one base station, and is configured to receive the unauthorized use of the user equipment. Frequency sent data.

As can be seen from the above, the spectrum resource scheduling apparatus of the second embodiment of the present invention considers that the user equipment can transmit part of the data by using the unlicensed spectrum resources that are competitive when the cell is created by using the unlicensed spectrum. The prior art does not take this into consideration. The base station for scheduling resources allocates spectrum resources to the user equipment according to the total amount of data to be sent currently buffered by the user equipment, so that the base station allocates uplink transmission resources to the user equipment. The uplink transmission resources actually needed by the user equipment are exceeded. Therefore, compared with the prior art, the spectrum resource scheduling apparatus provided by the second embodiment of the present invention can solve the problem of over-scheduled uplink transmission resources when the user equipment on the unlicensed spectrum performs data transmission.

As shown in FIG. 5, the third embodiment of the present invention provides a spectrum resource scheduling method, which is executed by a user equipment, and includes:

When the base station for scheduling resources is one, the step is specifically: sending the required uplink transmission resource to the base station for scheduling resources by using a buffer status report, to request the used resource for scheduling The base station performs resource scheduling according to the required uplink transmission resource. In this case, the method further includes: transmitting data to the base station for scheduling resources by using the unlicensed spectrum that is competitive.
