Description

Spectrum management device, electronic device, wireless communication method, and storage medium

The present application claims priority from chinese patent application filed 24/7/2019 under the name "spectrum management device, electronic device, wireless communication method, and storage medium" in chinese patent office, application No. 201910671510.4, the entire contents of which are incorporated herein by reference.

Technical Field

Embodiments of the present disclosure relate generally to the field of wireless communications, and in particular, to a spectrum management device, an electronic device, a wireless communication method, and a storage medium. More particularly, the present disclosure relates to a spectrum management device, an electronic device as a network-side device, a wireless communication method performed by the spectrum management device, a wireless communication method performed by the electronic device as the network-side device, and a computer-readable storage medium.

Background

With the evolution of wireless communication systems, users have increasingly demanded high quality, high speed, and new services. Operators and equipment manufacturers are constantly improving the systems to meet the service requirements of users, which requires a large amount of spectrum resources to support new services and meet the demand for high-speed communications. The spectral resources may be quantized with parameters such as time, frequency, bandwidth, maximum allowable transmit power, etc. While limited spectrum resources have been allocated to fixed operators and services, the newly available spectrum resources are very scarce and expensive. In this case, countries have started spectrum reallocation. For example, in some frequency bands, wireless network operators are allowed to apply license plates to obtain spectrum usage rights for a certain time.

Each operator may apply for license plates based on location. For example, the new communication system sends a spectrum authorization request to the spectrum management device based on the location, and the spectrum management device determines whether the new communication system can use the spectrum resources at the location. In the case where the spectrum management device rejects the spectrum authorization request of the new communication system, the new communication system needs to transmit the spectrum authorization request again based on the new location until the spectrum management device allows it to use the spectrum resources. In this process, the new communication system needs to continuously change the location and send a spectrum authorization request, and the spectrum management device also needs to continuously determine whether to allow the access of the new communication system, which inevitably causes excessive system overhead.

Therefore, it is necessary to provide a technical solution to improve the success rate of applying for license plate by the newly added communication system and to accelerate the speed of applying for license plate by the newly added communication system, so as to optimize the process of applying for license plate from the newly added communication system to the spectrum management device.

Examples of the present disclosure will now be described more fully with reference to the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.

Numerous specific details are set forth such as examples of specific components, devices, and methods to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms, and that neither should be construed to limit the scope of the disclosure. In certain example embodiments, well-known processes, well-known structures, and well-known technologies are not described in detail.

5. application examples.

<1. description of the problems >

Fig. 1(a) and 1(b) are diagrams illustrating a scenario in which a newly joined communication system requests spectrum resources at a desired location according to an embodiment of the present disclosure. The regions shown in fig. 1(a) and 1(b) are regions managed by the spectrum management apparatus. That is, the spectrum management apparatus manages spectrum resources in the area, for example, determines whether to allow a newly joined communication system to use the spectrum resources in the area, issues a spectrum license plate for the communication system, and charges an authorization cost to the communication system. In this context, the cost may include a fee. As shown in fig. 1(a) and 1(b), there are three communication systems already connected in the area managed by the spectrum management device, which are respectively labeled as an existing system 1, an existing system 2, and an existing system 3. A newly joining communication system (labeled as a new system in the figure) also desires to use spectrum resources in that area.

As shown in fig. 1(a), if the new system desires to use the spectrum resources at location a, an electronic device (e.g., a network-side device such as a base station) managing the new system may transmit spectrum authorization request information to a spectrum management device, and the spectrum management device determines whether to allow the new system to use the spectrum resources at location a. In the case where the spectrum management device determines that the new system is not allowed to use the spectrum resources at location a, the new system needs to request the spectrum management device to use the spectrum resources at other locations. As shown in fig. 1(B), the new system requests the use of the spectrum resource at location B, and the spectrum management device needs to determine again whether to allow the new system to use the spectrum resource at location B. If the spectrum management device does not allow the new system to use the spectrum resources at location B, the new system needs to change locations again until the spectrum management device allows it to use the spectrum resources.

Therefore, in the conventional license plate application process, a newly added communication system needs to continuously change the location and send a spectrum authorization request, and the spectrum management device also needs to continuously judge whether to allow the newly added communication system to access, which inevitably causes excessive system overhead.

For some specific frequency bands, some countries have some regions divided in advance, and a communication system using the frequency band applies for a spectrum using license plate of the frequency band by taking the region as a unit. Thus, the desired location of the new system may be a location point or a location area. There are an unlimited number of location points within the area managed by the spectrum management device, and a newly joined communication system needs to constantly change location areas and send a spectrum authorization request. In this process, since the newly added communication system does not know where to modify to successfully obtain the license plate, the probability of successfully obtaining the license plate is low, and the time taken to obtain the license plate may be long. As for the location area, although there are a limited number of location areas within the area managed by the spectrum management device, a newly added communication system also needs to constantly change the location area and transmit a spectrum authorization request, and thus there are also problems that the probability of successfully obtaining a license plate is reduced and it takes a long time.

The present disclosure provides a spectrum management device, an electronic device, a wireless communication method performed by the spectrum management device, a wireless communication method performed by the electronic device, and a computer-readable storage medium in a wireless communication system, so as to improve the success rate of applying for a license plate by a newly added communication system and accelerate the speed of applying for the license plate by the newly added communication system, thereby optimizing the process of applying for the license plate from the spectrum management device by the newly added communication system.

The wireless communication system according to the present disclosure may be a 5G NR (new radio) communication system. A wireless communication system may include one or more spectrum management devices, each managing spectrum resources within a range. That is, the management area of each spectrum management device may include a plurality of communication systems.

The electronic device according to the present disclosure may be a network side device that manages a communication system, and the network side device may be any type of TRP (Transmit and Receive Port). In addition, the network side device described in the present disclosure may also be a base station device, for example, an eNB, or may also be a gNB (base station in the 5 th generation communication system).

<2. configuration example of spectrum management apparatus >

Fig. 2 is a block diagram illustrating an example of a configuration of a spectrum management device 200 according to an embodiment of the present disclosure.

As shown in fig. 2, the spectrum management device 200 may include a determination unit 210, a location calculation unit 220, and a communication unit 230.

Here, each unit of the spectrum management device 200 may be included in the processing circuit. It should be noted that the spectrum management device 200 may include one processing circuit or may include a plurality of processing circuits. Further, the processing circuitry may include various discrete functional units to perform various different functions and/or operations. It should be noted that these functional units may be physical entities or logical entities, and that units called differently may be implemented by the same physical entity.

According to an embodiment of the present disclosure, the determining unit 210 may determine whether to allow the newly joined communication system to use the spectrum resources at a desired location. Here, the newly joined communication system refers to a communication system that has not accessed the area managed by the spectrum management device 200, which is different from a communication system that has accessed the area managed by the spectrum management device 200 (i.e., an existing communication system within the area managed by the spectrum management device 200). The newly joined communication system desires to use spectrum resources at a desired location within the area managed by the spectrum management device 200.

According to an embodiment of the present disclosure, in a case where the determining unit 210 determines that the newly joined communication system is not allowed to use the spectrum resource at the desired location, the location calculating unit 220 may calculate a recommended location where the newly joined communication system uses the spectrum resource. That is, the spectrum management apparatus 200 makes a recommendation of a location at which a newly joined communication system requests use of spectrum resources, the recommended location also being located within the area managed by the spectrum management apparatus 200.

According to an embodiment of the present disclosure, the spectrum management device 200 may transmit the recommended position to the electronic device managing the newly joined communication system through the communication unit 230. Here, the electronic device that manages the newly added communication system may be, for example, a network-side device, such as a base station device, in the newly added communication system.

As can be seen from this, according to the spectrum management device 200 of the embodiment of the present disclosure, in a case where a newly joined communication system is not allowed to use spectrum resources at a desired location, a location can be recommended to the newly joined communication system. Therefore, the newly added communication system can determine the position of the next frequency spectrum application according to the recommended position, so that the success rate of the newly added communication system for applying the license plate is improved, the speed of applying the license plate by the new communication system is increased, and the process of applying the license plate to the frequency spectrum management equipment by the new communication system is optimized.

According to an embodiment of the present disclosure, the recommended location includes one or more locations. That is, the position calculation unit 220 may calculate one recommended position or may calculate a plurality of recommended positions.

Further, according to the embodiments of the present disclosure, as described above, for some specific frequency bands, some countries have some regions divided in advance, and a communication system that needs to use the frequency band applies for a spectrum of the frequency band to use a license plate in units of regions. In this case, the desired position of the newly added communication system may be a position area, that is, the newly added communication system selects an area among the divided areas as the desired position. As such, each of the one or more recommended locations is also a location area. For other cases, a communication system needing to use spectrum resources can apply for spectrum using license plates in units of location points. In this case, the desired location of the newly joined communication system may be any one location point within the area managed by the spectrum management device. As such, each of the one or more recommended locations is also a location point. Herein, "location" may refer to a location point, and may also refer to a location area.

Further, according to embodiments of the present disclosure, the recommended position may be an absolute position, such as GPS position information. Further, the recommended position may also be a relative position with respect to the desired position, such as an offset in the horizontal and vertical axes with respect to the desired position.

According to an embodiment of the present disclosure, the determination unit 210 may determine whether to allow the newly joined communication system to use the spectrum resources at a desired location according to an interference value of the newly joined communication system to an existing communication system within an area managed by the spectrum management device 200. Here, the determination unit 210 may calculate an interference value of the newly joined communication system to each of one or more existing communication systems within the area managed by the spectrum management device 200 to determine whether to allow the newly joined communication system to use the spectrum resources at the desired location.

According to an embodiment of the present disclosure, the determining unit 210 may determine the interference situation of the newly added communication system to each existing communication system according to the transmission parameter information of the electronic device managing the newly added communication system. Here, the transmission parameter information includes a transmission power of the electronic device and/or an antenna parameter of the electronic device. The antenna parameters herein refer to parameters related to radiation of the antenna, such as radiation direction, beam direction, main lobe width, side lobe width, and the like. According to an embodiment of the present disclosure, the interference situation of the newly added communication system to each existing communication system may include whether the newly added communication system will generate interference to each existing communication system, and a value of the interference generated by the newly added communication system to the existing communication system for those existing communication systems that will generate interference to the existing communication system. Of course, the newly added communication system may not generate interference to the existing communication system, and the interference value of the newly added communication system to the existing communication system may be considered as zero.

According to an embodiment of the present disclosure, the spectrum management device 200 may receive spectrum authorization request information from the electronic device through the communication unit 230, wherein the spectrum authorization request information includes desired location information and transmission parameter information of the electronic device. That is, the spectrum authorization request information indicates that a newly joined communication system managed by the electronic device desires to obtain spectrum usage authorization at a desired location.

According to the embodiment of the present disclosure, after the spectrum management device 200 obtains the transmission parameter information and the expected location of the electronic device, the determining unit 210 may determine the interference situation of the newly added communication system to each existing communication system according to the transmission parameter information, the expected location information, and the location information of the existing communication system of the electronic device. Further, when the interference value of the newly joined communication system to any one of the existing communication systems exceeds the interference predetermined threshold, the determination unit 210 determines that the newly joined communication system is not allowed to use the spectrum resource at the desired location. When the newly added communication system does not cause interference to the existing communication systems, or the interference values of the newly added communication system to all the existing communication systems do not exceed the interference predetermined threshold, the determination unit 210 may determine to allow the newly added communication system to use the spectrum resources at the desired location. Here, the predetermined interference threshold may be set for each existing communication system, or the same predetermined interference threshold may be set for all existing communication systems.

Taking the scenario shown in fig. 1(a) as an example, it is assumed that the determination unit 210 calculates that the new system generates interference on the existing systems 1 and 3, generates no interference on the existing system 2, and generates an interference value I _1 for the existing system 1 and an interference value I _3 for the existing system 3. Here, the interference predetermined threshold is set to I _0 for both the existing system 1 and the existing system 3. For example, in the case where I _1 ≦ I _0 and I _3 ≦ I _0, the determination unit 210 may determine that the new system is allowed to use the spectrum resources at location A. As another example, where I _1 > I _0 and I _3 ≦ I _0, determination unit 210 may determine that the new system is not allowed to use the spectrum resources at location A. Similarly, in the case where I _1 ≦ I _0 and I _3 > I _0, the determination unit 210 may determine that the new system is not allowed to use the spectrum resources at location A.

Having described the determining unit 210 according to an embodiment of the present disclosure in detail above, the position calculating unit 220 according to an embodiment of the present disclosure will be described in detail below.

According to an embodiment of the present disclosure, the location calculation unit 220 may determine the recommended location where the newly joined communication system does not interfere with all existing communication systems more than the interference predetermined threshold according to the transmission parameter information of the electronic device and the interference predetermined threshold that the existing communication systems within the area managed by the spectrum management device 200 can tolerate.

Also, the spectrum management device 200 may receive spectrum authorization request information from the electronic device through the communication unit 230, thereby obtaining desired location information and transmission parameter information of the electronic device. The transmission parameter information includes a transmission power of the electronic device and/or an antenna parameter of the electronic device. Here, the location calculation unit 220 may determine, as the recommended location, a location within the area managed by the spectrum management device 200 where interference to all existing communication systems does not exceed the interference predetermined threshold, based on the transmission parameter information of the electronic device, the location information of the existing communication systems, and the interference predetermined threshold that can be tolerated by the existing communication systems.

According to an embodiment of the present disclosure, the location calculation unit 220 may determine the exclusive area of each existing communication system according to the transmission parameter information of the electronic device and a predetermined threshold of interference that each existing communication system can tolerate. Here, the exclusive area refers to the following area: the newly joined communication system interferes with the existing communication system within the exclusive area by more than a predetermined interference threshold, and the newly joined communication system interferes with the existing communication system outside the exclusive area by no more than the predetermined interference threshold. That is, the boundary of the exclusive area is a boundary whether the interference of the newly joined communication system to the existing communication system exceeds the interference predetermined threshold. Further, the position calculation unit 220 may determine the exclusive area of each existing communication system, thereby determining the recommended position according to the exclusive areas of all existing communication systems.

According to an embodiment of the present disclosure, the location calculation unit 220 may determine an area other than the exclusive areas of all existing communication systems among the areas managed by the spectrum management device as an available area. That is, in the available area, the interference of the newly joined communication system to all existing communication systems does not exceed the interference predetermined threshold. Further, the location calculation unit 220 may determine a recommended location in the available area according to a distance from the desired location. Here, the position calculation unit 220 may determine a position closer to the desired position in the usable area as the recommended position. That is, the position calculation unit 220 may determine a position closer to the desired position as the recommended position in an area where interference to all existing communication systems does not exceed the interference predetermined threshold.

According to an embodiment of the present disclosure, in a case where the position calculation unit 220 calculates one recommended position, the position calculation unit 220 may determine a position (which may be a position point or a position area) closest to the desired position in the available area as the recommended position. In the case where the position calculation unit 220 calculates a plurality of recommended positions, the position calculation unit 220 may determine the previous plurality of positions closer to the desired position in the usable area as the recommended positions.

As can be seen from this, according to the embodiment of the present disclosure, at the recommended position determined by the spectrum management device 200, the interference of the newly added communication system to all existing communication systems does not exceed the predetermined interference threshold, and therefore, the system requirement that the newly added communication system accesses the spectrum management device 200 can be satisfied. Further, since the recommended position can be determined according to the distance from the expected position, the recommended position is close to the expected position, so that the possibility of being adopted by the newly added communication system is high, and the requirement of the newly added communication system can be met to the greatest extent.

Fig. 3 is a schematic diagram illustrating a process of determining a recommended position according to an embodiment of the present disclosure. In fig. 3, for convenience of explanation, only a case where there are two existing communication systems (existing system 4 and existing system 5) is shown, and the coverage of the new system is not shown, only the desired location C of the new system, at which the new system desires to use spectrum resources, is shown. As shown in fig. 3, the operating area, i.e., the coverage area, of the existing system 4 and the existing system 5 is shown by the circles of the dotted lines. Further, the position calculation unit 220 may calculate the exclusive areas of the existing systems 4 and 5. In fig. 3, the circle of the solid line on the periphery of the operation area of existing system 4 shows the exclusion area of existing system 4, and the circle of the solid line on the periphery of the operation area of existing system 5 shows the exclusion area of existing system 5. Further, the position calculation unit 220 may calculate an available area. As shown in fig. 3, the rectangular area shows an area managed by the spectrum management apparatus 200, and an area other than the exclusive area of the existing system 4 and the exclusive area of the existing system 5 among the areas managed by the spectrum management apparatus 200 is an available area. Further, the position calculation unit 220 may determine the recommended position from the available area according to the distance from the desired position C. As shown in fig. 3, the position calculation unit 220 takes the position closest to the desired position C in the usable area as the recommended position. As shown in fig. 3, the location calculation unit 220 calculates a recommended location for the newly joined communication system. The position calculation unit 220 may calculate a plurality of recommended positions in a similar manner.

As described above, the spectrum management device 200 according to the embodiment of the present disclosure can recommend a location to a newly joined communication system. In this way, the newly joined communication system can determine a new expected location for the next spectrum authorization request based on the recommended location. That is, the spectrum management device 200 may receive new spectrum authorization request information carrying a new desired location from the electronic device managing the newly joined communication system through the communication unit 230 and determine whether to allow the newly joined communication system to use spectrum resources at the new desired location. The procedure of determining whether to allow the newly joined communication system to use the spectrum resources at the new desired location and the following procedures are similar to the foregoing and will not be described herein again.

According to the embodiment of the present disclosure, as shown in fig. 2, the spectrum management device 200 may further include a cost calculation unit 240 for calculating the authorization cost of the communication system.

According to an embodiment of the present disclosure, in a case where the determination unit 210 determines that the newly joined communication system is allowed to use the spectrum resources at the desired location, the spectrum management device 200 may allocate the spectrum resources to the newly joined communication system, and the cost calculation unit 240 may calculate the authorization cost of the newly joined communication system and recalculate the authorization cost of each existing communication system within the area managed by the spectrum management device 200.

According to an embodiment of the present disclosure, the cost calculation unit 240 may update the total operation cost required for the communication network managed by the spectrum management device 200, and calculate the authorization cost of the newly joined communication system and recalculate the authorization cost of each existing communication system according to the updated total operation cost. Here, the total operation cost means a total operation cost required for the spectrum management device 200 to manage all communication systems in its management area, for example, the total operation cost required for the spectrum management device 200 to manage all existing communication systems (existing system 4 and existing system 5) is S0, and there are:

S0＝S4+S5

where S4 denotes the authorization cost of the existing system 4, S5 denotes the authorization cost of the existing system 5, and S0 denotes the total operation cost required for the spectrum management device 200 to manage the existing system 4 and the existing system 5.

In the case where the newly joined communication system is allowed to use the spectrum resources at a desired location, the cost calculation unit 240 needs to calculate the total operation cost S0 '(generally, S0' > S0) required for the spectrum management apparatus 200 to manage all the existing communication systems as well as the newly joined communication system, and has:

S0＇＝S4＇+S5＇+S6。

where S4 ' represents the authorization cost of the existing system 4 recalculated by the cost calculating unit 240, S5 ' represents the authorization cost of the existing system 5 recalculated by the cost calculating unit 240, S6 represents the authorization cost of the new system calculated by the cost calculating unit 240, and S0 ' represents the total operation cost required for the spectrum management device 200 to manage the existing system 4 and the existing system 5 as well as the new system.

According to the embodiment of the present disclosure, when calculating the authorization cost of each communication system according to the operation cost, the cost calculation unit 240 may equally allocate the authorization cost of each communication system, i.e., S4 ═ S5 ═ S0/2, S4 ═ S5 ═ S6 ═ S0 ″/3. Alternatively, the cost calculating unit 240 may also allocate the authorization cost according to a certain proportion according to the actual situation of each communication system.

Further, according to the embodiment of the present disclosure, for a certain sub-area within the area managed by the spectrum management device 200, the cost calculation unit 240 may also determine whether the sub-area is a hot spot area according to the number of newly joined communication systems that expect to use spectrum resources within the sub-area within a predetermined period of time. Here, assuming that the number of newly joined communication systems that desire to use spectrum resources in the sub-area within a predetermined period of time is large, that is, a newly joined communication system frequently requests to use spectrum resources in the sub-area, it can be determined that the sub-area is a hot spot area.

According to the embodiment of the present disclosure, the cost calculating unit 240 may determine the authorized cost of the communication system using the spectrum resources in the sub-area according to whether the sub-area is a hot spot area. For example, for a communication system using spectrum resources in a hot spot region, the cost calculation unit 240 may increase the authorization cost appropriately.

As described above, according to the embodiment of the present disclosure, the cost calculation unit 240 may recalculate the authorization cost of each communication system when a new communication system is added, so that the authorization cost of each communication system is more reasonable. Here, since a new communication system is added to share the total operation cost of the entire wireless network, the authorization cost of the existing communication system may be reduced. In this case, the cost calculation unit 240 may transmit the recalculated authorization cost to the existing communication system to reduce the authorization cost of the existing communication system, thereby improving the satisfaction of the existing communication system.

According to an embodiment of the present disclosure, the spectrum management device 200 may transmit the authorization cost of the newly joined communication system to the electronic device through the communication unit 230. Here, the spectrum management device 200 may transmit grant authorization information indicating that the newly joined communication system is granted use of the spectrum resources, together with the authorization cost, to the electronic device. Further, the spectrum management device 200 can receive spectrum registration request information including information of granting a cost of authorization of a newly joined communication system from the electronic device through the communication unit 230. Further, the spectrum management device 200 can transmit the spectrum use confirmation information to the electronic device through the communication unit 230. Next, the newly joined communication system can normally use the spectrum resources at the desired location according to the authorization cost.

According to an embodiment of the present disclosure, after the spectrum management device 200 receives the spectrum registration request information, the spectrum management device 200 may further transmit the recalculated authorization cost of each existing communication system to the corresponding existing communication system. That is, after the spectrum management device 200 receives the spectrum registration request information, it may be determined that a newly joined communication system will join the network managed by the spectrum management device 200, and thus the recalculated authorization cost of other existing communication systems may be transmitted to the corresponding existing communication systems. In this way, existing communication systems that receive the recalculated authorization cost can be billed according to the new authorization cost.

As described above, according to the embodiments of the present disclosure, after the spectrum management device calculates the authorization cost for the newly added communication system, the authorization cost may be transmitted to the newly added communication system to determine that the newly added communication system can obtain the spectrum usage license plate after the newly added communication system confirms the authorization cost.

According to an embodiment of the present disclosure, the spectrum authorization request information transmitted by the electronic device managing the newly joined communication system may include cost range information indicating a range of authorization costs that the newly joined communication system can accept. In this way, the spectrum management device 200 can compare the cost range after calculating the authorization cost of the newly-added communication system. Further, in a case where the authorization cost of the newly joined communication system is within the cost range, the spectrum management device 200 may determine that the calculated authorization cost can be accepted by the newly joined communication system. In this case, the spectrum management device 200 can directly transmit, to the electronic device, the consent authorization information indicating that the newly joined communication system is allowed to use the spectrum resources at the desired location and the authorization cost of the newly joined communication system through the communication unit 230.

As described above, according to the embodiment of the present disclosure, the newly added communication system may carry cost range information in the spectrum authorization request information, so that the spectrum management device 200 determines whether the calculated authorization cost can be accepted by the newly added communication system, thereby omitting the step of determining the authorization cost with the newly added communication system after calculating the authorization cost, further saving the signaling flow, and speeding up the speed of obtaining the spectrum license plate by the newly added communication system.

As can be seen, according to the embodiments of the present disclosure, in a case where a newly joined communication system is not allowed to use spectrum resources at a desired location, the spectrum management device 200 can recommend a location to the new communication system. Therefore, the newly added communication system can determine the position of the next frequency spectrum application according to the recommended position, so that the success rate of the new communication system for applying the license plate is improved, and the speed of the new communication system for applying the license plate is increased. Here, the recommended position determined by the spectrum management device 200 may avoid causing serious interference to the existing communication system, and at the same time, the recommended position is close to the desired position, so that the requirement of the newly added communication system may be satisfied to the maximum extent. Further, in a case where a newly joined communication system is allowed to use spectrum resources at a desired location, the spectrum management device 200 may calculate an authorization cost for each communication system, thereby making the authorization cost for each communication system reasonable. In summary, according to the embodiments of the present disclosure, the process of a newly joined communication system applying for a license plate to a spectrum management device can be optimized.
