Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to a spectrum resource scheduling method, device and system. Background Art

[0002] With the development of wireless applications, the demand for large bandwidth services is increasing and widely used. Large bandwidth service demands include large bandwidth cloud collaboration services in the cell uplink (UL), such as taking photos and uploading them to the cloud, playing cloud games, etc. In the current wireless communication system, there are multiple base stations deployed by operators, and each base station can only provide spectrum resources for user equipment (UE) according to the spectrum resources actually allocated by the operator.

[0003] However, since each operator is allocated limited spectrum resources belonging to different frequency bands and each operator operates independently, the spectrum resources that can be provided to the UE by a base station deployed by an operator are limited, and sometimes it is impossible to provide corresponding spectrum resources according to the UE's large-bandwidth service requirements. Summary of the invention

[0004] The present application provides a spectrum resource scheduling method, device and system, which can provide larger spectrum resources, that is, larger transmission bandwidth according to the needs of UE without changing the spectrum resource allocation of the operator.

[0005] In a first aspect, the present application provides a spectrum resource scheduling method, comprising: sending a first application message to a first base station, the first application message being used to request the first base station to authorize the use of a first spectrum resource, the first spectrum resource being determined according to service scheduling requirements and a frequency band supported by the first base station; receiving a first authorization message, the first authorization message being used to indicate the first spectrum resource that the first base station is authorized to use; sending a second application message to a second base station, the second application message being used to request the second base station to authorize the use of a third spectrum resource, and informing the second base station of the first spectrum resource that has been authorized to use, the third spectrum resource being determined according to the service scheduling requirements and a frequency band supported by the second base station; accepting service scheduling by the second base station on a second spectrum resource, the second spectrum resource including the first spectrum resource, or the second spectrum resource including the first spectrum resource and the third spectrum resource.

[0006] The base stations deployed by each operator have the ability to perform service scheduling on their respective allocated frequency bands, but each operator operates independently, so a base station deployed by an operator can only perform service scheduling within its allocated frequency range. Since the spectrum resources allocated to each operator are limited, even if a UE can be served by multiple operators, each service scheduling can only be performed by one of the base stations on the spectrum resources authorized by the operator to which it belongs. Therefore, the spectrum resources that the UE can use are limited. Once the UE needs to transmit a large amount of business, the spectrum resources are insufficient. The spectrum resource scheduling method provided in the present application authorizes the UE to use its corresponding spectrum resources through multiple base stations serving the UE, so that the UE can obtain sufficient spectrum resources for business transmission. As described in the method, the first base station authorizes the UE to use the first spectrum resources. When the UE applies for spectrum resources from the second base station, the second base station can obtain the first spectrum resources authorized by the first base station and determine to schedule services for the UE on the second spectrum resources. The second spectrum resources include the first spectrum resources and the third spectrum resources within the frequency range corresponding to the second base station. If the first spectrum resources are insufficient to provide sufficient first spectrum resources for the service scheduling demands of the UE, the second spectrum resources determined by the second base station may include all the first spectrum resources and the third spectrum resources allocated by the second base station for the insufficient part, so as to solve the problem of insufficient spectrum resources that the first base station can provide for the current service scheduling demands of the UE, effectively increase the total service volume of service scheduling, and solve the problem of insufficient bandwidth. If the first base station can provide sufficient spectrum resources, the second spectrum resources may only include the first spectrum resources, and the first spectrum resources may also be scheduled by the second base station, which makes it easier for the UE to flexibly select the base stations corresponding to different operators for service scheduling. For example, the UE can select a base station with better signal strength to achieve the current service scheduling demands.

[0007] Optionally, the UE first sends a first application message to the first base station to obtain authorization for the first spectrum resource, and then informs the second base station of the authorized first spectrum resource. The second base station determines the third spectrum resource based on the authorized first spectrum resource, the service scheduling requirements and the frequency band supported by the second base station. For example, the UE needs to apply for 50M service transmission, and the first base station authorizes the first spectrum resource required for 40M service transmission. The second base station can allocate the third spectrum resource required for the remaining 10M service transmission to the UE on the frequency band it supports based on the first spectrum resource required for the 40M service transmission authorized by the first base station and the total 50M service that the UE needs to transmit. In this case, the second spectrum resources include the first spectrum resources for transmitting the 40M service and the third spectrum resources for transmitting the 10M service. The second base station can perform service scheduling for the UE on the second spectrum resources.

[0008] Optionally, the UE can send a first application message to the first base station to obtain authorization for the first spectrum resources, and send a second application message to the second base station to obtain authorization for the third spectrum resources. At this time, the first base station determines the first spectrum resources based on the service scheduling requirements and the frequency bands supported by the first base station, and the second base station determines the third spectrum resources based on the service scheduling requirements and the frequency bands supported by the second base station.

[0009] In one possible implementation, the method also includes: receiving a second authorization message, the second authorization message is used to indicate that the second base station is authorized to use the third spectrum resource; based on the first authorization message and the second authorization message, sending a first message indicating the first spectrum resource and the third spectrum resource to the target base station, so that the target base station determines the second spectrum resource based on the first message and performs service scheduling on the second spectrum resource, wherein the target base station is the first base station or the second base station; accepting service scheduling of the target base station on the second spectrum resource.

[0010] In this application, the UE has the ability to access multiple base stations, such as those deployed by two different operators. By sending application messages to the two operators respectively, the spectrum resources authorized by the corresponding base stations of the two operators are obtained, and then one of the base stations is selected as the target base station to uniformly schedule the authorized spectrum resources, that is, the spectrum resources authorized by the first base station or the second base station are used to realize the unified scheduling of spectrum resources between different operators. This method does not affect the independent operation between different operators and does not increase the operating costs such as spectrum resource changes. This method can flexibly configure spectrum resources by the target base station, improve the utilization and flexibility of spectrum resources without affecting the existing network and changing the spectrum resource allocation, and effectively solve the problem of insufficient bandwidth provided by the independently operated operator for the service scheduling of the UE.

[0011] In a second aspect, the present application provides a spectrum resource scheduling method, including: receiving a first application message sent by a UE, the first application message being used to request a first base station to authorize the use of a first spectrum resource; if it is determined that the UE is authorized to use the first spectrum resource based on the service scheduling requirements of the UE and the frequency band supported by the first base station, a first authorization message is sent to the UE, the first authorization message being used to indicate that the first base station is authorized to use the first spectrum resource.

[0012] In one possible implementation, if the UE selects the first base station as the target base station, the first message sent to the first base station includes the first spectrum resource authorized by the first base station and the third spectrum resource authorized by the second base station. The first base station aggregates the spectrum resources and performs service scheduling on the second spectrum resource. That is, the method also includes: if the first message is received, the second spectrum resource is determined according to the first spectrum resource and the third spectrum resource indicated by the first message, wherein the first message is obtained by the UE according to the received first authorization message and the second authorization message, the second spectrum resource includes the first spectrum resource, or the second spectrum resource includes the first spectrum resource and the third spectrum resource, the second authorization message is sent to the UE by the second base station according to the second application message of the UE, and the third spectrum resource is the spectrum resource authorized for use by the second base station; and the service of the UE is scheduled on the second spectrum resource.

[0013] Optionally, the first base station determines the first spectrum resources based on service scheduling requirements and a frequency band supported by the first base station.

[0014] In one possible implementation, the method further includes: reconfiguring a bandwidth part (Bandwidth Part, BWP) of the UE according to the second spectrum resource. After the second spectrum resource is obtained by aggregation, the BWP of the UE may be modified or reconfigured according to the second spectrum resource, i.e., the spectrum resource actually used for service scheduling of the UE.

[0017] In one possible implementation, if the UE selects the second base station as the target base station, the first message sent to the second base station includes the first spectrum resource authorized by the first base station and the third spectrum resource authorized by the second base station. The second base station aggregates the spectrum resources and schedules services on the second spectrum resources. That is, the method also includes: sending a second authorization message to the UE, the second authorization message is used to indicate that the second base station is authorized to use the third spectrum resource; if the first message is received, determining the second spectrum resource according to the first spectrum resource and the third spectrum resource indicated by the first message, wherein the first message is obtained by the UE according to the received first authorization message and the second authorization message, and the first authorization message is sent to the UE by the first base station according to the first application message of the UE, and the first application message is used to request the first base station to authorize the use of the first spectrum resource; and scheduling services for the UE on the second spectrum resource.

[0018] Optionally, the second base station determines the third spectrum resources based on the first spectrum resources that have been authorized for use, the service scheduling requirements and the frequency bands supported by the second base station, or the second base station determines the third spectrum resources based on the service scheduling requirements and the frequency bands supported by the second base station.

[0055] In order to enable those skilled in the art to better understand the solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0056] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0057] The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects rather than to describe a specific order of objects. For example, a first target object and a second target object are used to distinguish different target objects rather than to describe a specific order of target objects.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0059] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more than two. For example, multiple processing units refer to two or more processing units; multiple systems refer to two or more systems.

[0060] For ease of understanding, the following first explains the relevant nouns or terms used in the embodiments of the present application:

[0061] 1. Large bandwidth

[0062] Usually, a server bandwidth of 100Mbps or 1000Mbps can be defined as a large bandwidth. Services that use large bandwidth are generally services that consume a lot of bandwidth and have high demand for traffic resources, such as videos, short videos, cloud viewing, etc.

[0063] 2. Bandwidth

[0064] Bandwidth usually refers to the width of the frequency band occupied by a signal. Wireless communication is based on the frequency domain, and the communication channels between its devices (including base stations and UEs, etc.) are based on the frequency of electromagnetic waves. It can be understood that the band for information transmission between devices is the electromagnetic wave, and bandwidth can usually be expressed in MHz.

[0065] 3. Carrier Aggregation (CA)

[0066] Aggregate one or more independent carriers to obtain a larger transmission bandwidth.

[0067] 4. Intra-band Carrier Aggregation (Intra-band CA)

[0068] Aggregation is performed between different carriers in the same band, including contiguous and non-contiguous carrier aggregation.

[0069] 5. Inter-band Carrier Aggregation (Inter-band CA)

[0070] Carriers of different bands are aggregated.

[0071] 6. BWP

[0072] It is a subset of the total cell bandwidth. It flexibly adjusts the UE receiving and transmitting bandwidth size through bandwidth adaptation in the new wireless technology (New Radio, NR), so that the UE receiving and transmitting bandwidth does not need to be as large as the cell bandwidth.

[0073] The spectrum resource scheduling method provided in the embodiment of the present application can be applied in wireless communication scenarios. In a wireless communication network, spectrum resources of different frequency ranges or different frequency bands of the same frequency band (i.e., the same band) can be allocated to different operators, and they are operated independently by different operators. Each operator can be allocated limited spectrum resources. For example, the n3 frequency band includes spectrum resources of 1710MHz–1785MHz, such as Figure 1 As shown, n3 is a frequency band. Assume that the n3 frequency band is allocated to three operators for independent operation. The frequency band allocated to operator A is 1710MHz-1735MHz, the frequency band allocated to operator B is 1735MHz-1765MHz, and the frequency band allocated to operator C is 1765MHz-1785MHz. Based on the division of this frequency band, the base station deployed (set up) by each operator only schedules services for UE within its corresponding frequency range.

[0074] In some instances, base stations deployed by various operators have the ability to schedule services in the entire n3 frequency band (i.e., 1710MHz-1785MHz). However, since each operator operates independently, base stations deployed by one operator can only schedule services through spectrum resource allocation within the frequency range allocated to it. Figure 1 The base stations deployed by operator A can only perform service scheduling in the authorized frequency range of 1710MHz-1735MHz, the base stations deployed by operator B can only perform service scheduling in the authorized frequency range of 1735MHz-1765MHz, and the base stations deployed by operator C can only perform service scheduling in the authorized frequency range of 1765MHz-1785MHz. For a UE, it can access at least one base station deployed by an operator, be provided with services by at least one operator, and perform service scheduling. For example, if a UE purchases SIM card 1 of operator A and SIM card 2 of operator B to access the network and meet service transmission requirements, then when the UE uses SIM card 1 to access the network, it can perform service scheduling on 1710MHz-1735MHz through the base station deployed by operator A; when it uses SIM card 2 to access the network, it can perform service scheduling on 1735MHz-1765MHz through the base station deployed by operator B. From the above description, it can be seen that the spectrum resources allocated to each operator are limited. Even if a UE can be provided with services by multiple operators, when accessing a base station, service scheduling can only be performed on the spectrum resources allocated to the operator to which the base station belongs. Therefore, the spectrum resources that the UE can use are limited.

[0075] Typically, the scheduling strategy for service scheduling includes scheduling of multiple-input multiple-output (MIMO) layers (Layer or Rank), modulation order, code rate, and bandwidth. Assuming that the UE is within the cell coverage of a base station and needs to schedule service A, the scheduling strategy for service A may include transmitting data through multiple layers, setting the modulation order (quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (QAM), 64QAM, 256QAM or 1024QAM, etc.) and code rate, as well as a certain bandwidth (MHz). In some instances, if the service A of the UE is scheduled, and the UE is at the edge of the cell where the signal is weak, in order to preserve performance, the base station scheduling strategy will be adjusted. Usually, the number of MIMO layers, modulation order and / or code rate can be lowered to increase the transmission bandwidth. This is because the number of MIMO layers, modulation order and code rate are greatly affected by the network signal strength. Lowering them accordingly at locations with weak signals can ensure the performance of data transmission. When the number of MIMO layers, modulation order and / or code rate are lowered, the size of the data that the UE needs to transmit is positively correlated to the size of the bandwidth. That is, if a certain service of the UE, such as service A, needs to transmit a large amount of business during service scheduling, the bandwidth needs to be increased to ensure the transmission capacity.

[0076] The embodiment of the present application provides a spectrum resource scheduling method, which provides a larger spectrum resource, that is, a larger bandwidth, according to the needs of the UE when the spectrum resources available to the UE are limited but a large amount of business needs to be transmitted. This method can allow different operators to share spectrum resources through the UE without changing the spectrum resource allocation of the operator, and provide a larger transmission bandwidth according to the business requirements of the UE to ensure the transmission of business volume. Figure 2 is a flow chart of a spectrum resource scheduling method provided in an embodiment of the present application, such as Figure 2 As shown, the method is executed by the UE, including but not limited to steps S101 to S104.

[0077] Figure 3 is a schematic diagram of a scenario architecture provided in an embodiment of the present application, Figure 3 The scenarios provided are examples for illustration purposes only. Figure 1 , assuming that UE 30 has SIM cards of operator A and operator B, that is, it can schedule services on the spectrum resources of operator A and operator B, such as Figure 3As shown, the base station set by operator A is the first base station 10 , the base station set by operator B is the second base station 20 , and the UE 30 is within the network signal coverage of the first base station 10 and the second base station 20 .

[0078] S101. UE sends a first application message to a first base station, where the first application message is used to request the first base station to authorize the use of first spectrum resources. The first spectrum resources are determined according to service scheduling requirements and frequency bands supported by the first base station.

[0079] Service scheduling request means that when a UE needs to transmit a service, it requests the network to allocate the spectrum resources required for the service transmission. Figure 3 In the scenario, UE 30 can access the first base station 10 and the second base station 20 at the same time, or can first access the first base station 10 or the second base station 20 according to the operator currently required by the UE, and then switch to another base station when necessary. If the UE has accessed the second base station of operator B, it requests the second base station to allocate the spectrum resources required for service transmission.

[0080] Take the case where the UE has accessed the second base station for service scheduling as an example. If the UE's current service scheduling requirement is a service transmission volume of 50M, but the UE is at the edge of the cell covered by the second base station, under low bit rates, such as QPSK, and one-layer transmission, the bandwidth allocated by the second base station cannot meet the service scheduling requirement of the large bandwidth. The UE can determine that the bandwidth that the second base station can provide is insufficient based on the poor network status encountered during the current service transmission, such as network freezes, and send a first application message to the first base station. The first application message can carry the service volume that the UE needs to transmit and / or request the use right of the first spectrum resource corresponding to the transmission of the service volume. If the first base station authorizes the use of the first spectrum resource, the authorized UE informs the second base station of the authorized first spectrum resource, and the second base station can expand the scheduling of more spectrum resources to achieve the scheduling requirement of the current service. Alternatively, the UE can first inform the second base station of the UE's current service scheduling demand, such as informing the second base station that 500M service scheduling is currently required. The second base station receives the UE's current service scheduling demand, and determines based on the service scheduling demand that the bandwidth that can be provided to the UE is insufficient for 500M service scheduling, and feeds back a message of insufficient bandwidth resources to the UE. After receiving the message, the UE sends a first application message to the first base station to request authorization to use the first spectrum resources, so that the second base station can expand the scheduling of more spectrum resources to achieve the current service scheduling demand.

[0081] The first application message is used to request the first base station to authorize the use of the first spectrum resource. If the first base station authorizes the first spectrum resource to be used by the UE, the first base station no longer schedules services on the first spectrum resource. Figure 1For example, the first application message is used to request the first base station to determine a portion of spectrum resources from its allocated frequency band (such as 1710MHz-1735MHz) as the first spectrum resource. After the first base station agrees to the application of the first application message and authorizes the first spectrum resource to the UE, it can inform other base stations such as the second base station through the UE that service scheduling can be performed on the first spectrum resource. After the first base station authorizes the first spectrum resource, it will no longer use the first spectrum resource for service scheduling, avoiding the situation where two base stations deployed by different operators use the first spectrum resource for service scheduling at the same time.

[0082] Optionally, before sending the first application message to the first base station, the UE may also inform the first base station of the UE's current service scheduling request, such as sending a message to the first base station separately to inform the service scheduling request, or carrying the service scheduling request in the first application message, such as the first application message includes requesting the first base station to authorize the use of the first spectrum resources for transmitting 500M service volume.

[0083] The spectrum resource scheduling method provided in the embodiment of the present application can be applied to service scheduling on UL spectrum resources when the UE needs a large-bandwidth service, and can also be applied to service scheduling on downlink (DownLink, DL) spectrum resources. The embodiment is illustrated by taking UL as an example, and the DL method refers to UL and will not be elaborated on.

[0084] S102. The UE receives a first authorization message, where the first authorization message is used to indicate a first spectrum resource that is authorized for use by a first base station.

[0085] For example, if the UE informs the first base station that the current service scheduling demand of the UE is a service volume of 500M, the first base station can authorize the first spectrum resource accordingly based on the maximum service volume transmission that the base station can provide for the UE. For example, if the first base station can provide the UE with a spectrum resource for transmitting a service volume of 350M, then the first spectrum resource authorized for use by the first base station can be a spectrum resource capable of transmitting a service volume of 350M. The first spectrum resource that the first base station agrees to authorize can be configured according to actual conditions and is not limited to the examples in the embodiments of the present application.

[0086] Optionally, after the first base station authorizes the first spectrum resource to be used by the UE, it may mark the first spectrum resource to indicate that the first spectrum resource will no longer be scheduled for use by other UEs, so as to avoid conflicts in the use of the first spectrum resource.

[0087] S103. The UE sends a second application message to the second base station. The second application message is used to request the second base station to authorize the use of a third spectrum resource and inform the second base station of the first spectrum resource that has been authorized for use. The third spectrum resource is determined based on service scheduling requirements and a frequency band supported by the second base station.

[0088] After the UE accesses the second base station, it can send a second application message to the second base station. Optionally, the UE can determine the amount of business that can be transmitted by the first spectrum resource based on the first authorization message fed back by the first base station, and calculate the remaining amount of business to be transmitted based on the total amount of business that needs to be transmitted according to the current business scheduling demand of the UE, and apply to the second base station for spectrum resources within the frequency band of the second base station based on the remaining amount of business to be transmitted through the second application message. For example, the current business scheduling demand of the UE is to transmit 500M of business volume, and the UE obtains the first spectrum resource with 350M of business volume authorized by the first base station through the first application message. Then, the UE can apply to the second base station for 150M of third spectrum resources for business scheduling through the second application message; or After the UE sends a message including a service scheduling request and an authorized first spectrum resource to the second base station, the second base station determines to provide the UE with a third spectrum resource on its supported frequency band based on the amount of service that can be transmitted by the first spectrum resource and the total amount of service that needs to be transmitted for the UE's current service scheduling request. For example, the UE's current service scheduling request is to transmit 500M of service, and the UE obtains the first spectrum resource authorized by the first base station to transmit 350M of service through the first application message. Then the UE can inform the second base station through the second application message that the service volume of the authorized first spectrum resource is 350M, and the total service volume that needs to be transmitted for the current service scheduling request is 500M. Based on this, the second base station determines to authorize the UE to transmit a third spectrum resource with a 150M service volume.

[0089] Optionally, the total service volume required by the current service scheduling request of the UE may be notified to the second base station through a second application message, or may be notified to the second base station through other messages.

[0090] S104. The UE accepts service scheduling on the second spectrum resources by the second base station, where the second spectrum resources include the first spectrum resources, or the second spectrum resources include the first spectrum resources and the third spectrum resources, wherein the third spectrum resources are spectrum resources authorized for use by the second base station.

[0091] After the UE informs the second base station of the first spectrum resources authorized by the first base station, the second base station can coordinate and determine the second spectrum resources on the first spectrum resources and the third spectrum resources based on the first spectrum resources authorized by the first base station for use by the UE, combined with the available spectrum resources within the frequency band of the second base station and the service scheduling requirements of the UE, and perform service scheduling for the UE on the second spectrum resources.

[0092] Optionally, the second spectrum resources include only the first spectrum resources, and the second spectrum resources include all the first spectrum resources and part of the third spectrum resources. Among them, if the first spectrum resources are not enough to provide sufficient spectrum resources for the service scheduling demands of the UE, the second spectrum resources determined by the second base station may include all the first spectrum resources and the third spectrum resources allocated by the second base station for the insufficient part, so as to solve the problem of insufficient spectrum resources that the first base station can provide for the current service scheduling demands of the UE, effectively increase the total service volume of service scheduling, and solve the problem of insufficient bandwidth. If the first base station can provide sufficient spectrum resources, the second spectrum resources may include only the first spectrum resources, and the first spectrum resources may also be scheduled by the second base station, which makes it easier for the UE to flexibly select the base stations corresponding to different operators for service scheduling. For example, the UE can select a base station with better signal strength to achieve the current service scheduling demands.

[0093] Figure 4 is a flow chart of another spectrum resource scheduling method provided in an embodiment of the present application, such as Figure 4 As shown, the method is executed by the UE, the first base station and the second base station, including but not limited to steps S201 to S206.

[0094] S201. UE sends a first application message to a first base station.

[0095] S202: If the first base station determines to authorize the UE to use the first spectrum resource according to the service scheduling requirement of the UE and the frequency band supported by the first base station, the first base station sends a first authorization message to the UE.

[0096] The content carried in the first application message and the first authorization message can refer to the above example and will not be described in detail. In the first authorization message, the time domain and frequency domain positions of the first spectrum resource that can be authorized.

[0097] After receiving the first application message from the UE, the first base station determines the service volume of the UE's service scheduling request based on the first application message, the spectrum resources that can be used in the frequency band allocated to the operator corresponding to the first base station, and determines the first spectrum resources to be authorized to the UE.

[0098] In order to avoid the situation where base stations of multiple operators transmit data on the first spectrum resource at the same time, after the first base station is authorized, service scheduling is no longer performed on the first spectrum resource.

[0099] S203. The UE receives a first authorization message.

[0100] S204. The UE sends a second application message to the second base station.

[0101] The content carried in the second application message can refer to the above example and will not be repeated here.

[0102] Optionally, the second application message sent by the UE to the second base station may carry the time domain and frequency domain position of the first frequency domain resources indicated in the first authorization message, so as to inform the second base station of the time domain and frequency domain position of the first spectrum resources that the first base station has been authorized to use. Alternatively, the UE sends a separate message to the second base station based on the first authorization message, indicating the time domain and frequency domain position of the first frequency domain resources that the first base station has been authorized to use.

[0103] S205. The second base station receives a second application message.

[0104] S206. The second base station determines a second spectrum resource according to the first spectrum resource and the third spectrum resource, and schedules services for the UE on the second spectrum resource.

[0105] The second base station may determine the second spectrum resource according to the first spectrum resource and the third spectrum resource. The spectrum resource content included in the second spectrum resource may refer to the above example and will not be elaborated herein.

[0106] For example, the second base station determines the service volume required for the UE's service scheduling demands and the time domain and frequency domain positions of the first spectrum resources that the first base station has authorized for use based on the second application message, determines the time domain and frequency domain positions of the third spectrum resources based on the spectrum allocated to the operator corresponding to the second base station, and then determines the time domain and frequency domain positions of the second spectrum resources based on the first spectrum resources and the third spectrum resources and refers to the method provided in the above example, and performs service scheduling for the UE at the time domain and frequency domain positions of the second spectrum resources.

[0107] In some instances, since each operator independently builds its network and operates independently without interconnection, the second base station of operator B can first be synchronized when using the spectrum resources of the corresponding frequency band of operator A. For example, the first base station and the second base station are synchronized with the Global Navigation Satellite System (GNSS), thereby ensuring time and frequency synchronization to ensure that the second base station can be scheduled on the first spectrum resources, or to ensure that the second base station can be uniformly coordinated and scheduled on the first spectrum resources and the third spectrum resources.

[0108] Furthermore, there are four situations in which the frequency bands of the first spectrum resource and the third spectrum resource exist. When the second spectrum resource includes the first spectrum resource and the third spectrum resource, the second base station can perform different carrier aggregation (CA) according to the situation that the first spectrum resource and the third spectrum resource belong to different frequency bands: if the frequency bands where the first spectrum resource and the third spectrum resource are located are different frequency domain ranges of the same band, refer to Figure 1, the first spectrum resource is the spectrum resource in the frequency band allocated by operator A, and the third spectrum resource is the spectrum resource in the frequency band allocated by operator B. The second base station can allocate the third spectrum resource adjacent to the first spectrum resource, that is, the second spectrum resource can be used as a whole resource block for service scheduling or through intra-band contiguous carrier aggregation (Intra-band Contiguous CA) for service scheduling. If the third spectrum resource and the first spectrum resource are not adjacent, the second base station performs service scheduling through intra-band non-contiguous carrier aggregation (Intra-band Non-contiguous CA); if the frequency bands where the first spectrum resource and the third spectrum resource are located are different frequency domains of the same band, refer to Figure 1 , the first spectrum resource is a spectrum resource in the frequency band allocated by operator A, and the third spectrum resource is a spectrum resource in the frequency band allocated by operator C. The second base station can aggregate the first spectrum resource and the third spectrum resource into the second spectrum resource through intra-band non-contiguous carrier aggregation (Intra-band non-contiguous CA); if the first spectrum resource and the third spectrum resource belong to different bands, refer to Figure 5 The first spectrum resource is the spectrum resource in the frequency band allocated to operator A, and the third spectrum resource is the spectrum resource in the frequency band allocated to operator D. After the second base station obtains the scheduling capability of another band, it can aggregate the first spectrum resource and the third spectrum resource into the second spectrum resource through inter-band carrier aggregation (Inter-band CA).

[0109] S207. The UE accepts service scheduling from the second base station on the second spectrum resources.

[0110] In one possible implementation, the second base station or the target base station reconfigures the BWP of the UE based on the second spectrum resource. For example, after the second base station aggregates and obtains the second spectrum resource, it can also modify or reconfigure the BWP of the UE based on the second spectrum resource, that is, the spectrum resource actually used for service scheduling of the UE, so that the allocated BWP meets the size of the UE's sending and receiving bandwidth.

[0111] In the embodiment of the present application, if the UE has SIM cards of both operator A and operator B, it means that the UE is qualified to apply to operator A and operator B for service scheduling on their spectrum resources. The UE applies to the first base station of operator A for authorization of spectrum resources and obtains authorization to use the first spectrum resources. The first base station no longer performs service scheduling on its authorized first spectrum resources. Then, the UE informs the second base station of operator B of the authorized first spectrum resources, and the second base station obtains the ability to schedule the first spectrum resources of operator A and the third spectrum resources of operator B. In this way, the UE can obtain the spectrum resources required for greater business volume transmission, and realize high-speed, large-bandwidth business transmission in the network covered by the second base station. In the case of limited spectrum resources of a single operator, the demand for large-bandwidth business transmission is met.

[0112] Figure 6 is a flow chart of another spectrum resource scheduling method provided in an embodiment of the present application, such as Figure 6 As shown, the method is executed by the UE, the first base station and the second base station, including but not limited to steps S301 to S310.

[0113] The contents carried in the first application message, the first authorization message, the second application message, the second authorization message, the first spectrum resource, the second spectrum resource and the third spectrum resource in S301 to S308 can all be described in the above example and will not be repeated here.

[0114] S301. UE sends a first application message to a first base station.

[0115] S302. The first base station receives a first application message, sends a first authorization message to the UE based on the first application message, and no longer performs service scheduling on the first spectrum resource.

[0116] S303. The UE receives a first authorization message.

[0117] There is no sequence relationship between S301 and S304, and the first base station and the second base station have completed synchronization.

[0118] S304. The UE sends a second application message to the second base station.

[0119] S305. The second base station receives the second application message, sends a second authorization message to the UE based on the second application message, and does not perform service scheduling on the third spectrum resources.

[0120] S306. The UE receives a second authorization message.

[0121] S307. The UE sends a first message indicating the first spectrum resource and the third spectrum resource to the target base station according to the first authorization message and the second authorization message.

[0122] Among them, the target base station is the first base station or the second base station. For example, the UE can select the target base station according to the network signal strength of the current location. If the UE determines that the network signal strength of the first base station is higher, it determines that the first base station is the target base station; or, the UE can determine the target base station according to the selection of the user (the user using the UE), etc.

[0123] For the convenience of illustration (such as Figure 6 ), taking the UE selecting the second base station as the target base station as an example for explanation, the UE selecting the first base station as the target base station can refer to this example, and no further details will be given.

[0124] The UE can determine the time domain and frequency domain position of the first spectrum resource based on the first authorization message, determine the time domain and frequency domain position of the third spectrum resource based on the second authorization message, and inform the target base station of the information of the first spectrum resource and the third spectrum resource, that is, the time domain and frequency domain information, through the first message.

[0125] S308: If the second base station (target base station) receives the first message, it determines the second spectrum resource according to the first spectrum resource and the third spectrum resource indicated by the first message.

[0126] The target base station may determine the second spectrum resource according to the first message by referring to the method for determining the second spectrum resource in S103.

[0127] Optionally, the target base station may determine that the second spectrum resources include all the first spectrum resources. If the first spectrum resources are sufficient to meet the bandwidth required by the UE's business, all the first spectrum resources are configured in the second spectrum resources; if the first spectrum resources are insufficient to meet the bandwidth required by the UE's business, all the first spectrum resources and part of the third spectrum resources are configured in the second spectrum resources so that the second spectrum resources meet the bandwidth required by the UE's business. Since the first base station has authorized the use of the first spectrum resources to the second base station and no longer transmits data on the first spectrum resources, the second base station makes full use of the first spectrum resources to meet the UE's business requirements, which can effectively save spectrum resources in the second base station without causing waste of resources. It can not only realize the sharing of spectrum resources between different operators, but also save spectrum resources to the greatest extent and improve resource utilization.

[0128] S309: The second base station (target base station) schedules services for the UE on the second spectrum resources.

[0129] S310. UE accepts service scheduling on second spectrum resources from a second base station (target base station).

[0130] In a possible implementation manner, the target base station reconfigures the BWP according to the second spectrum resources. This step may refer to S207. After the target base station configures the BWP, it may configure time-frequency resources for service transmission in the BWP.

[0131] In some scenarios where wireless networks are actually used, when a UE is located at the edge of a cell covered by a base station, even at the maximum bandwidth allocated by the operator corresponding to the base station, the code rate at the edge of the cell is still low, which is not enough to provide the UE with a large bandwidth service transmission demand. Alternatively, when the UE is located in the center of the cell, there will still be a situation where its service scheduling demand for bandwidth is greater than the peak network speed that the base station at the current location can provide, that is, the UE's bandwidth demand is still not met. Considering that each operator operates independently, if it is necessary to share the spectrum resources of different operators, it is necessary for operators to share and build a network, but the difficulty of hetero-frequency networking is high, and there will be problems such as poor network performance, complex network conditions, and high requirements for hardware equipment in the network. Based on these problems, the embodiment of the present application provides a method for realizing spectrum resource sharing through UE, and the UE triggers the dynamic unified coordinated scheduling of spectrum resources between hetero-operators, such as operator A and operator B (that is, the spectrum resources authorized by the first base station or the second base station are used to realize the unified scheduling of spectrum resources by hetero-operators), and the hetero-operators can still maintain independent operations. The method allows the base station performing service scheduling to flexibly configure spectrum resources, thereby improving the utilization and flexibility of spectrum resources without affecting the existing network or changing the spectrum resource allocation, and effectively solving the problem of insufficient bandwidth provided by a single operator for UE service scheduling.

[0132] In addition, the embodiment of the present application takes the example that the UE has the ability to access base stations of two different operators, such as SIM cards of two operators installed on the UE. In practical applications, if the wireless network includes three or more operators, the method can be referred to, and at least two operators authorize the use of their spectrum resources, and then another operator determines the spectrum resources for final service scheduling based on the authorized spectrum resources, which is not limited to the scheduling method of the two operators' authorized spectrum resources listed in the embodiment of the present application.

[0133] This embodiment of the application provides a UE, Figure 7 is a schematic diagram of the structure of a UE provided in an embodiment of the present application, such as Figure 7 As shown, UE 30 includes: a sending module 301 and a receiving module 302.

[0134] The sending module 301 is used to send a first application message to the first base station, where the first application message is used to request the first base station to authorize the use of a first spectrum resource, where the first spectrum resource is determined according to service scheduling requirements and a frequency band supported by the first base station.

The third spectrum resources are determined according to the service scheduling requirements and the frequency bands supported by the second base station.

[0137] The receiving module 302 is further configured to receive service scheduling of the second base station on the second spectrum resources, where the second spectrum resources include the first spectrum resources, or the second spectrum resources include the first spectrum resources and the third spectrum resources.

[0138] In one possible implementation, the receiving module 302 is also used to receive a second authorization message, where the second authorization message is used to indicate that the second base station is authorized to use the third spectrum resource; the sending module 301 is also used to send a first message indicating the first spectrum resource and the third spectrum resource to the target base station based on the first authorization message and the second authorization message, so that the target base station determines the second spectrum resource based on the first message and performs service scheduling on the second spectrum resource, wherein the target base station is the first base station or the second base station; the receiving module 302 is also used to accept service scheduling of the target base station on the second spectrum resource.

[0139] In a possible implementation, the first spectrum resource and the third spectrum resource may be adjacent spectrum resources, and the second spectrum resource may refer to Figure 5 , obtained through different CA methods.

[0140] It should be understood that Figure 7 The modules shown are only examples.

[0142] The receiving module 101 is used to receive a first application message sent by a UE, where the first application message is used to request a first base station to authorize the use of a first spectrum resource.

[0143] The sending module 102 is used to send a first authorization message to the UE if the processing module 103 determines to authorize the UE to use the first spectrum resource according to the UE's service scheduling requirements and the frequency band supported by the first base station. The first authorization message is used to indicate that the first base station is authorized to use the first spectrum resource.

[0144] In one possible implementation, the processing module 103 is also used to determine the second spectrum resource based on the first spectrum resource and the third spectrum resource indicated by the first message if the receiving module 101 receives the first message, wherein the first message is obtained by the UE based on the received first authorization message and the second authorization message, and the second spectrum resource includes the first spectrum resource, or the second spectrum resource includes the first spectrum resource and the third spectrum resource, and the second authorization message is sent to the UE by the second base station based on the second application message of the UE, and the third spectrum resource is the spectrum resource authorized for use by the second base station; the scheduling module 104 is used to schedule services for the UE on the second spectrum resource.

[0145] In a possible implementation manner, the processing module 103 is further configured to reconfigure the BWP of the UE according to the second spectrum resources.

[0148] The receiving module 201 is used to receive a second application message sent by the UE, where the second application message is used to request the second base station to authorize the use of a third spectrum resource and to inform the second base station of the first spectrum resource that has been authorized for use. The third spectrum resource is determined based on service scheduling requirements and a frequency band supported by the second base station, and the first spectrum resource is determined by the first base station based on service scheduling requirements and a frequency band supported by the first base station.

[0149] The scheduling module 202 is used to schedule services for the UE on a second spectrum resource according to the second application message, where the second spectrum resource includes the first spectrum resource, or the second spectrum resource includes the first spectrum resource and a third spectrum resource.

[0150] In one possible implementation, the sending module 203 is used to send a second authorization message to the UE, and the second authorization message is used to indicate that the second base station is authorized to use the third spectrum resource; the processing module 204 is also used to determine the second spectrum resource based on the first spectrum resource and the third spectrum resource indicated by the first message if the receiving module 201 receives the first message, wherein the first message is obtained by the UE based on the received first authorization message and the second authorization message, and the first authorization message is sent to the UE by the first base station based on the first application message of the UE, and the first application message is used to request the first base station to authorize the use of the first spectrum resource; the scheduling module 202 is also used to schedule services for the UE on the second spectrum resource determined by the processing module 204.
