Description

Method, device and equipment for sharing spectrum resources

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a device for sharing spectrum resources.

Background

With the development of mobile communication technology, users using old communication systems gradually migrate to users using new communication systems, for example, users using third generation mobile communication technology (3 rd-generation mobile communication technology, 3G) gradually migrate to users using fourth generation mobile communication technology (4 rd-generation mobile communication technology, 4G) or fifth generation mobile communication technology (5 rd-generation mobile communication technology, 5G), etc.

The migration of users has led to an increasing idleness of the spectrum of old communication systems, such as 3G communication systems, and an increasing tension of the spectrum of new communication systems, such as 4G or 5G communication systems, etc. However, there is still a problem that users use the old communication system and users using the old communication system may remain in a certain number for a long time, so how to alleviate the problem that the limited frequency spectrum of the new communication system is more and more intense in the case that the old communication system is continuously operated becomes an important point of currently operating the new communication system.

In practical applications, in view of the fact that the spectrum of the old communication system is usually idle, a part of spectrum resources in the spectrum of the old communication system are generally shared to the new communication system, so as to increase the spectrum resources of the new communication system. However, in order to guarantee the basic service of users using the old communication system, the old communication system has limited spectrum resources shared to the new communication system, and the new communication system still faces the problem of spectrum shortage.

Disclosure of Invention

The embodiment of the application provides a method, a device and equipment for sharing spectrum resources, which are used for relieving the problem of shortage of spectrum resources of a new communication system.

In a first aspect, an embodiment of the present application provides a method for sharing spectrum resources, where the method includes: the method comprises the steps that a first base station generates sharing information of exclusive spectrum resources aiming at the first base station according to a first running state of the first base station, wherein the sharing information characterizes that the exclusive spectrum resources of the first base station can be shared by a second base station; the first running state of the first base station is specifically that the first base station does not process a target service currently or the first base station is in an uplink and downlink compressed mode, and the target service comprises an online voice service and/or a real-time data transmission service; the first base station sends the sharing information to the second base station. In this embodiment, when the first base station does not currently process the target service or the first base station is in the uplink and downlink compressed mode, the first base station may notify the second base station to occupy the exclusive spectrum resource of the first base station (of course, the second base station may occupy the shared spectrum resource of the first base station in a limited manner), so that, since the second base station may occupy all the spectrum resources of the first base station, the spectrum resources of the second base station are increased, the problem of shortage of spectrum resources of the second base station is further alleviated, and the second base station may enjoy the full bandwidth gain.

In some possible embodiments, the method further comprises: the first base station adjusts the unshared spectrum resource of the first base station into a target spectrum resource; the bandwidth of the target spectrum resource is smaller than that of the exclusive spectrum resource, the frequency band of the target spectrum resource is symmetrical about the center frequency point of the available frequency band of the first base station, and the available frequency band comprises the frequency band of the exclusive spectrum resource and the frequency band of the shared spectrum resource of the first base station. In this embodiment, after the exclusive spectrum resource of the first base station is adjusted to the target spectrum resource, the bandwidth of the target spectrum resource is smaller than the bandwidth of the exclusive spectrum resource before adjustment, which increases the spectrum resource bandwidth of the shared spectrum resource of the first base station, so that the second base station can occupy more spectrum resources when occupying the shared spectrum resource of the first base station, and further, the problem of shortage of spectrum resources of the second base station is further alleviated. Moreover, the target spectrum resource is symmetrical about the central frequency point of the available frequency band of the first base station, and the frequency band of the central symmetry reserves low-frequency information, so after the exclusive spectrum resource of the first base station is compressed to the target spectrum resource symmetrical about the central frequency point, the first base station can still reserve a large amount of useful information when transmitting signals to the access terminal based on the target spectrum resource, thereby the first base station can still keep the access terminal online based on the target spectrum resource.

In some possible implementations, the shared information includes an idle slot GAP interval for the uplink and downlink compressed mode when the first base station is in the uplink and downlink compressed mode. In this embodiment, the second base station may use the exclusive spectrum resources of the first base station by using a time division multiplexing manner, that is, after the first base station sends the GAP interval to the second base station, since the first base station does not transmit a radio frame to the access terminal in the GAP interval, the second base station may use the exclusive spectrum resources of the first base station in the GAP interval, so that the second base station may use all spectrum resources of the first base station in the GAP interval, and the problem of shortage of spectrum resources of the second base station may be further alleviated.

In some possible embodiments, the method further comprises: the first base station acquires occupation information of the second base station for shared spectrum resources of the first base station, wherein the occupation information indicates frequency bands occupied by the second base station in the shared spectrum resources; the first base station determines residual spectrum resources in the shared spectrum resources according to the occupation information, wherein the frequency bands of the residual spectrum resources are not occupied by the second base station; the first base station occupies the remaining spectrum resources. In this embodiment, the second base station does not necessarily occupy all bandwidths of the shared spectrum resource when occupying the shared spectrum resource of the first base station, so the first base station may occupy the unused remaining spectrum resource of the second base station in the shared spectrum resource for the usage situation of the shared spectrum resource by the second base station, so as to improve the utilization ratio of the spectrum resource by the first base station and the second base station.

In some possible embodiments, the method further comprises: the first base station generates the sharing stopping information aiming at the exclusive spectrum resource of the first base station according to the second running state of the base station, wherein the sharing stopping information characterizes the exclusive spectrum resource which can not be shared by the second base station; and the first base station sends the sharing stopping information to the second base station. In this embodiment, when the first base station currently has an online voice service or a real-time data transmission service, the first base station needs to occupy the exclusive spectrum resource to process the service, and at this time, the first base station may send the sharing stopping information to the second base station to instruct the second base station to stop occupying the exclusive spectrum resource of the first base station. In this way, the first base station may have sufficient spectrum resources to handle traffic.

In a second aspect, an embodiment of the present application further provides a method for sharing spectrum resources, where the method includes: the second base station receives shared information of the exclusive spectrum resource for the first base station; and the second base station shares the unshared spectrum resource of the first base station according to the sharing information. In this embodiment, the second base station may occupy the exclusive spectrum resource of the first base station based on the shared information of the first base station (of course, the second base station preferentially occupies the shared spectrum resource of the first base station), so that the second base station may occupy all spectrum resources of the first base station, which increases the spectrum resources of the second base station, further alleviates the problem of shortage of spectrum resources of the second base station, and the second base station may enjoy the complete bandwidth gain.

In some possible implementations, the sharing information further includes an idle slot GAP interval of the compressed mode, and the second base station shares, according to the sharing information, an exclusive spectrum resource of the first base station, including: the second base station determines a GAP interval of the compression mode when the first base station is in the uplink and downlink compression mode according to the sharing information; the second base station shares the first base station's unshared spectrum resources within the GAP interval. In this embodiment, the second base station may use the spectrum resources exclusive to the first base station in the GAP interval, so that the second base station may use all spectrum resources of the first base station in the GAP interval, and the problem of spectrum resource shortage of the second base station may be further alleviated.

In some possible embodiments, the method further comprises: the second base station generates occupation information of shared spectrum resources aiming at the first base station, wherein the occupation information indicates frequency bands in the shared spectrum resources occupied by the second base station; and the second base station sends the occupation information to the first base station. In this embodiment, when the second base station occupies the shared spectrum resource of the first base station, the first base station may be notified of the occupation information of the shared spectrum resource, so that the first base station may occupy the remaining spectrum resources in the shared spectrum resource according to the occupation information, thereby improving the utilization ratio of the first base station and the second base station for the spectrum resource.

In some possible embodiments, the method further comprises: the second base station receives the information of stopping sharing of the unshared spectrum resource for the first base station; and the second base station stops occupying the unshared spectrum resources of the first base station according to the sharing stopping information. In this embodiment, if the first base station needs to continuously occupy the unshared spectrum resource, for example, the first base station currently has an online voice service or a real-time data transmission service, the first base station may send the sharing stopping information to the second base station. In this way, the second base station may cease to occupy the exclusive spectrum resources of the first base station based on the ceasing sharing information, so that the first base station may have sufficient spectrum resources to process the traffic.

In a third aspect, an embodiment of the present application further provides an apparatus for sharing spectrum resources, where the apparatus is applied to a first base station, and the apparatus includes: a first generating unit, configured to generate, according to a first operation state of the first base station, sharing information for an exclusive spectrum resource of the first base station, where the sharing information characterizes that the exclusive spectrum resource of the first base station can be shared by a second base station; the first running state of the first base station is specifically that the first base station does not process a target service currently or the first base station is in an uplink and downlink compressed mode, and the target service comprises an online voice service and/or a real-time data transmission service; and the first sending unit is used for sending the sharing information to the second base station.

In some possible embodiments, the apparatus further comprises: an adjusting unit, configured to adjust the unshared spectrum resource of the first base station to a target spectrum resource; the bandwidth of the target spectrum resource is smaller than that of the exclusive spectrum resource, the frequency band of the target spectrum resource is symmetrical about the center frequency point of the available frequency band of the first base station, and the available frequency band comprises the frequency band of the exclusive spectrum resource and the frequency band of the shared spectrum resource of the first base station.

In some possible implementations, when the first base station is in the uplink and downlink compressed mode, the shared information includes an idle slot GAP interval of the compressed mode.

Detailed Description

Currently, due to the shortage of spectrum resources of the new communication system, the old communication system generally shares a part of spectrum resources to the new communication system to increase spectrum resources of the new communication system. However, in order to guarantee the basic service of users using the old communication system, the old communication system needs to reserve certain spectrum resources. For example, for a universal mobile telecommunications system (universal mobile telecommunications system, UMTS), both it and a long term evolution (long term evolution, LTE) telecommunications system can occupy 5MHz (megahertz) of spectrum resources. Typically, the 5MHz spectrum resources occupied by UMTS may include a 2.4MHz single-shared spectrum resource and a 2.6MHz shared spectrum resource, where UMTS may share the 2.6MHz shared spectrum resource to the LTE communication system, so that the spectrum resources of the LTE communication system may be increased to 7.6MHz (i.e., 5mhz+2.6 MHz), as shown in fig. 1. UMTS still requires reserving the remaining 2.4MHz of the unshared spectrum resources and continuously transmitting UMTS signals to the access terminal during the unshared spectrum interval to maintain the access terminal on-line. The UMTS is less interfered by the LTE communication system when continuously transmitting the UMTS signal in the unshared spectrum interval, and the distortion of the UMTS signal is in an acceptable range. If the spectrum resources of UMTS are continuously compressed, so that the spectrum resources which are exclusively shared by the access terminal are compressed to below 2.4MHz, the access terminal of UMTS is unacceptable because of distortion of the received UMTS signal, and thus access or communication abnormality occurs between the access terminal of UMTS and UMTS.

Thus, although the available spectrum resources of the new communication system are increased, the new communication system cannot occupy the whole spectrum resources of the old communication system, and cannot enjoy a complete bandwidth gain in the regular n×5MHz spectrum total bandwidth scenario. For example, the total bandwidth of the operator 2100M spectrum is 10MHz, and is allocated to UMTS and LTE, so LTE can occupy only 7.6MHz spectrum resources at most. Even when UMTS traffic is low, such as UMTS ONLY carries the last part of M2M, UMTS ONLY terminals that cannot migrate, the 2.4MHZ exclusive spectrum resource cannot be shared for LTE, although UMTS remains lightly loaded in the reserved 2.4MHZ exclusive spectrum interval.

Based on this, the embodiment of the application provides a method for sharing spectrum resources, which enables a new communication system to share all spectrum resources of an old communication system by enabling a base station of the new communication system to share exclusive spectrum resources of a base station of the old communication system, so that the problem of shortage of spectrum resources of the new communication system can be further relieved, and the new communication system can enjoy a complete bandwidth gain. In particular. The first base station may generate, according to an operation state of the first base station, sharing information for the exclusive spectrum resource of the first base station, where the sharing information characterizes that the exclusive spectrum resource of the first base station may be shared by the second base station, and the operation state of the first base station may specifically be an operation state when the first base station does not currently process a target service or the first base station is in an uplink and downlink compressed mode, where the target service includes an online voice service and/or a real-time data transmission service, and then the first base station may send the sharing information to the second base station. In this way, the second base station can share the exclusive spectrum resource of the first base station according to the received sharing information.

It can be understood that, when the first base station does not process the target service, the first base station occupies the shared spectrum resource and only needs to send a signal for keeping the access terminal continuously online to the access terminal, at this time, even if the second base station also occupies the exclusive spectrum resource of the first base station, the first base station sends a signal on the exclusive spectrum resource, and the interference caused when the second base station occupies the exclusive spectrum resource to process the service is also small, and in the case that the second base station occupies the exclusive spectrum resource to process the service, the first base station can also simultaneously keep the access terminal continuously online based on the exclusive spectrum resource, i.e. when the first base station and the second base station use the exclusive spectrum resource simultaneously, the processing of the respective service is not affected. When the first base station is in the uplink and downlink compressed mode, the second base station can occupy the exclusive spectrum resources of the first base station in the gap of the data transmission from the first base station to the terminal, so that the second base station can occupy all spectrum resources of the first base station in a part of time slices. The second base station can occupy all the spectrum resources of the first base station, so that the spectrum resources of the second base station are increased, the problem of shortage of the spectrum resources of the second base station is further relieved, and the second base station can enjoy complete bandwidth gain.

As an example, the embodiment of the present application may be applied to an exemplary application scenario as shown in fig. 2. In this scenario, both the UMTS-based base station NodeB and the LTE-based base station eNodeB are allocated with 5MHz spectrum resources, and the UMTS NodeB may share its own 5MHz spectrum resources (including 2.6MHz shared spectrum resources and 2.4MHz exclusive spectrum resources) to the LTE eNodeB to increase the spectrum resources available to the LTE eNodeB.

Specifically, when determining that the current running state reaches a preset condition, for example, the current unprocessed online voice service, the real-time data transmission service and the like, the UMTS NodeB may generate shared information for the own 2.4MHz unique spectrum resource, where the shared information characterizes that the 2.4MHz unique spectrum resource of the UMTS NodeB may be shared by the LTE eNodeB, and then the UMTS NodeB may send the shared information to the LTE eNodeB. In this way, the LTE eNodeB may share not only the 2.6MHz shared spectrum resource of the UMTS NodeB, but also the 2.4MHz exclusive spectrum resource of the UMTS NodeB according to the shared information, thereby increasing the spectrum resources available to the LTE eNodeB.

The Base Station (BS) in the embodiment of the present application may be a device on an access network side for supporting a terminal to access a communication system, for example, may be an evolved node b (eNB) in a 4G access technology communication system, a next generation base station (next generation nodeB, gNB) in a 5G access technology communication system, a transmission receiving point (transmission reception point, TRP), a relay node (relay node), an Access Point (AP), or a base station that may occur in the future with the evolution of a wireless communication technology, and so on. The base station may be fixed or mobile. A base station may be referred to as an access network device or a network device, etc.

It will be appreciated that the above scenario is merely an example of one scenario provided by embodiments of the present application, and embodiments of the present application are not limited to this scenario. For example, in other possible application scenarios, the old communication system and the new communication system may not be limited to the above examples, e.g., when a 4G user migrates to a 5G user, the old communication system may be a 4G-related communication system, and the new communication system may be a 5G-related communication system, etc.; for another example, the UMTS NodeB and the LTE eNodeB may communicate via a predefined low-latency channel. In summary, the embodiments of the present application may be applied to any applicable scenario, and are not limited to the scenario examples described above.

In order that the above objects, features and advantages of the present application will be more readily understood, a more particular description of various non-limiting embodiments of the application will be rendered by reference to the appended drawings. It will be apparent that the described embodiments are some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for sharing spectrum resources according to an embodiment of the present application, where the method may specifically include:

s301: the first base station generates shared information for the unshared spectrum resources of the first base station according to the first operating state of the first base station. The shared information characterizes that the unshared spectrum resource of the first base station can be shared by the second base station, and the first operation state of the first base station can be specifically that the first base station does not process a target service currently or the first base station is in an uplink and downlink compressed mode, wherein the target service comprises an online voice service and/or a real-time data transmission service.

In order for different communication systems to be able to support and handle the traffic of the respective users, the allocated spectrum resources of the different communication systems are typically different. For example, assuming that the total of the spectrum resources is 10MHz, after being allocated to UMTS and LTE, UMTS can separate the 5MHz spectrum resources therein, and the remaining 5MHz spectrum resources of LTE. UMTS and LTE respectively handle services of corresponding users, such as online voice services, real-time data transmission services, etc., based on respective spectrum resources.

In this embodiment, the first base station may share its own spectrum resource to the second base station, so as to increase the spectrum resource available to the second base station. In practical applications, the first base station in this embodiment may be a base station based on an old communication system, for example, may be a UMTS NodeB, etc., and correspondingly, the second base station in this embodiment may be a base station of a new communication system, for example, an LTE eNodeB, etc. As the spectrum resources of the new communication system become more and more intense, the old communication system may share its own spectrum resources to the new communication system. It should be noted that the new communication system and the old communication system described in this embodiment are determined based on migration of the user using the communication system, for example, when the 4G user migrates to the 5G user, the communication system implementing 4G communication is the old communication system in this embodiment, and the communication system implementing 5G communication is the new communication system in this embodiment. By sharing the spectrum resources of the first base station to the second base station, the problem of spectrum resource shortage of the second base station can be alleviated.

Typically, the spectrum resources allocated by the first base station generally include two parts, one part is a shared spectrum resource, i.e. the shared spectrum resource may be shared by the second base station, and the other part is an unshared spectrum resource, i.e. the unshared spectrum resource may only be occupied by the first base station. When the traffic volume processed by the first base station is very low, the first base station occupies the exclusive spectrum resource and generally only processes the basic traffic of the user, and the first base station keeps a light load state. At this time, the unshared spectrum resource may not be fully utilized by the base station, and when the spectrum resource of the second base station is in a tense state, the unshared spectrum resource of the first base station may be idle.

Therefore, in this embodiment, the first base station may not only share its own shared spectrum resource to the second base station, but also share its own exclusive spectrum resource to the second base station, so as to further increase the spectrum resources available to the second base station. In particular implementation, the first base station may generate, according to the first state information of the first base station, sharing information for the unshared spectrum resource of the first base station, where the sharing information characterizes that the unshared spectrum resource of the first base station may be shared by the second base station, so that the sharing information is used to instruct the second base station to occupy the unshared spectrum resource of the first base station.

The first base station may instruct the second base station to occupy the exclusive spectrum resource of the first base station when determining that the first base station is in the first operation state. Specifically, the first operation state of the first base station may specifically be that the first base station does not currently process the target service, where the target service includes an online voice service and/or a real-time data transmission service, and the like. It can be appreciated that when the first base station occupies the exclusive spectrum resource to process the online voice service and/or the real-time data transmission service, if the second base station also occupies the exclusive spectrum resource to process the service supported by the second base station, the first base station and the second base station may affect each other when simultaneously occupying the exclusive spectrum resource, or even cause that the first base station and the second base station may not be able to successfully process the corresponding service. However, when the first base station is not currently processing online voice traffic and/or real-time data transmission traffic, the first base station may occupy the exclusive spectrum resource only for simply listening to channels such as downlink pilot to maintain continuous online of the access terminal. At this time, if the second base station also occupies the exclusive spectrum resource of the first base station, the first base station occupies the exclusive spectrum resource to send a signal to the access terminal, so that the influence on the service processing performed by the second base station by occupying the exclusive spectrum resource is weaker, and the second base station can still successfully process the corresponding service under the interference of the first base station based on the exclusive spectrum resource. Meanwhile, the second base station occupies the exclusive spectrum resource to perform service processing, so that the influence on the online process of the first base station for maintaining the access terminal is weak, i.e. the first base station can also successfully maintain the online of the access terminal. Thus, when the first base station is not currently processing the target service, the first base station and the second base station use the independent spectrum resources of the first base station at the same time, but the interference generated by the first base station and the second base station is not enough to influence the first base station to keep the access terminal online and the second base station successfully realize the processing service.

In the above embodiment, when the first base station is in the light load state, the exclusive spectrum resource is shared with the second base station, and in other possible embodiments, even if the first base station is processing the target service, the second base station may use the exclusive spectrum resource of the first base station by means of time division multiplexing. Specifically, when the first base station is in the uplink and downlink compressed mode, an idle GAP exists between the partial radio frames sent by the first base station to the access terminal. The compressed mode is a mechanism that generates a certain idle period in the radio frame, through which the access terminal of the first base station can perform measurements of inter-frequency or inter-system cells. In practice, the compressed mode is a technique used in wideband code division multiple access (wideband code division multiple access, WCDMA) and frequency division duplex (frequency division duplexing, FDD) modes. In WCDMA system FDD mode, the access terminal of the first base station needs to make measurements of the target cell for handover in preparation for inter-frequency hard handover, FDD to time division duplex (time division duplexing, TDD) handover and inter-system handover. The frequency of these measurements is typically different from the frequency at which the current access terminal is operating, i.e., inter-frequency measurements need to be performed, and the access terminal may complete the inter-frequency measurements within the GAP interval.

Because the first base station does not transmit the radio frame to the access terminal in the GAP interval, that is, the first base station does not occupy the exclusive spectrum resource of the first base station in the GAP interval to transmit the radio frame to the access terminal, the second base station can multiplex the exclusive spectrum resource of the first base station in the GAP interval to process the service supported by the second base station. Based on the shared information, the shared information generated by the first base station may further include GAP interval information of the compressed mode of the first base station, so that the second base station can determine, based on the shared information, a GAP interval in which the first base station does not transmit a radio frame to the access terminal, and further can perform service processing in the GAP interval by using the exclusive spectrum resource of the first base station. In practical applications, after the first base station is in the compressed mode, the second base station may be notified of the GAP pattern in the compressed mode, where the GAP pattern may be carried in the shared information and sent to the second base station, or may be sent separately to the second base station.

Further, the first base station may transmit a radio frame to the access terminal during the GAP interval while not occupying the exclusive spectrum resource, and may still transmit a signal to the access terminal or other access terminals during the GAP interval via a Control Channel (CCH) to maintain the presence of the access terminals. Based on this, in the GAP interval, the first base station may reduce the transmission power of the signal, so as to reduce interference caused by multiplexing the exclusive spectrum resource with the second base station to perform service processing when the first base station transmits the signal in the GAP interval.

It should be noted that, in some practical application scenarios, the access terminal of the first base station generally does not demodulate and receive data in the GAP interval of the compressed mode, so that the interference caused by the second base station on the access terminal of the first base station when multiplexing the unshared spectrum resource for service processing is generally smaller, or even has no influence, so that the service processing of the first base station is not influenced when the second base station multiplexes the unshared spectrum resource in the GAP interval.

S302: the first base station transmits the shared information to the second base station.

In this embodiment, after generating the shared information, the first base station may send the shared information to the second base station, so as to notify the second base station that the shared information may occupy the exclusive spectrum resource of the first base station.

In some possible embodiments, the first base station and the second base station may have a predefined low-latency channel therebetween, so that the first base station may send the generated shared information to the second base station through the low-latency channel, so that the shared information can be transmitted to the second base station in a short time. Of course, the first base station may also transmit the shared information to the second base station in other manners, which will not be described herein.

In practical applications, when the spectrum resources of the second base station are tense, the first base station may be requested to share the unshared spectrum resources to the second base station. If the first base station determines that the second base station is allowed to share the exclusive spectrum resource, the sharing information aiming at the exclusive spectrum resource can be generated and sent to the second base station; if the first base station determines that the second base station is not allowed to share the spectrum resources, for example, the first base station is currently processing the target service, the load is larger, and the like, the second base station may be notified that the second base station is not allowed to occupy the spectrum resources of the first base station.

S303: and the second base station shares the unshared spectrum resource of the first base station according to the received sharing information.

The second base station can occupy the exclusive spectrum resources of the first base station under the instruction of the shared information, so that the available spectrum resources of the second base station are increased, the problem of shortage of the spectrum resources of the second base station is relieved, and the second base station can enjoy complete bandwidth gain.

It should be noted that, if the first base station does not process the target service currently, the second base station may not be limited by time when sharing the exclusive spectrum resource of the first base station, i.e., the second base station may continuously occupy the exclusive spectrum resource of the first base station. If the first base station is currently in the uplink and downlink compressed mode, the second base station may determine a GAP interval of the compressed mode according to the received sharing information, and share the unshared spectrum resource of the first base station in the GAP interval. For example, as shown in fig. 4, the LTE eNodeB may share the exclusive spectrum resources of 2.4HMz of the UMTS NodeB in the GAP interval.

In order to further reduce the influence on the processing service of the second base station occupying the exclusive spectrum resource when the first base station uses the exclusive spectrum resource to perform signal transmission when the second base station occupies the exclusive spectrum resource of the first base station, in this embodiment, the exclusive spectrum resource of the first base station may be compressed and adjusted. Specifically, when the second base station needs to occupy the exclusive spectrum resource of the first base station, the first base station may adjust the exclusive spectrum resource to the target spectrum resource. The bandwidth of the target spectrum resource is smaller than the bandwidth of the unshared spectrum resource before adjustment, the frequency band of the target spectrum resource is symmetrical with respect to the center frequency point of the available frequency band of the first base station, and the available frequency band of the first base station comprises the frequency band of the unshared spectrum resource before adjustment and the frequency band of the shared spectrum resource of the first base station. For example, before the adjustment of the unshared spectrum resource of the first base station, the unshared spectrum resource (2.4 MHz) and the shared spectrum resource (2.6 MHz) of the first base station may be as shown in fig. 5, and after the adjustment of the unshared spectrum resource of the first base station, the unshared spectrum resource of the first base station may be compressed and adjusted to the target spectrum resource shown in fig. 5, the bandwidth of the target spectrum resource may be any bandwidth of 1.2MHz to 2.4HMz, and the target spectrum resource shown in fig. 5 is 1.2MHz.

It should be noted that, after the spectrum resources of the first base station are adjusted to the target spectrum resources, since the bandwidth of the target spectrum resources is smaller than the bandwidth of the spectrum resources of the first base station before adjustment, the influence of the service processing on the spectrum resources of the first base station occupied by the second base station when the first base station keeps the access terminal online based on the target spectrum resources can be further reduced. That is, as shown in fig. 5, before the adjustment of the exclusive spectrum resource of the first base station, the first base station control channel interference received by the second base station is 2.4HMz, and after the adjustment of the exclusive spectrum resource of the first base station to the target spectrum resource, the first base station control channel interference received by the second base station is reduced to 1.2MHz, and accordingly, the second base station can not be interfered by the first base station when performing service processing based on the spectrum resource of the other 1.2 HMz.

Meanwhile, the target spectrum resource is symmetrical about the central frequency point of the available frequency band of the first base station, and the frequency band which is symmetrical about the central frequency point reserves low-frequency information, so after the exclusive spectrum resource of the first base station is compressed to the target spectrum resource which is symmetrical about the central frequency point, the first base station can still reserve a large amount of useful information when transmitting signals to the access terminal based on the target spectrum resource, and the first base station can still keep the access terminal online based on the target spectrum resource.

In practical applications, the second base station may preempt the shared spectrum resource of the first base station before sharing the unshared spectrum resource of the first base station, and notify the first base station of the frequency band in the shared spectrum resource occupied by the second base station. In particular, when the second base station needs to increase available spectrum resources, occupancy information of the shared spectrum resources of the first base station may be generated, where the occupancy information indicates a frequency band in the shared spectrum resources of the first base station occupied by the second base station, and then the second base station may send the occupancy information to the first base station. In this way, the first base station can determine the residual spectrum resources in the shared spectrum resources of the first base station according to the received occupation information, and the frequency band of the residual spectrum resources is not occupied by the second base station, so that the first base station can occupy the residual spectrum resources to process corresponding services by using the residual spectrum resources.

For example, as shown in fig. 6, the LTE eNodeB (the above second base station) may notify the UMTS NodeB, specifically, notify a dynamic filter (dynamic filter) in the UMTS NodeB, of spectrum resource information (hereinafter referred to as first occupancy information for convenience of description) currently required to be occupied by itself through a low-latency channel with the UMTS NodeB (the above first base station) through a physical resource block scheduler (physical resource block). Wherein, the first occupation information specifically characterizes spectrum resources occupied by the LTE eNodeB; when the UMTS NodeB and the LTE eNodeB are integrated in the same device, the LTE eNodeB may send the first occupancy information to the UMTS NodeB through the internal private interface of the device. The dynamic filter in the UMTS NodeB may determine remaining available spectrum resource information of the UMTS NodeB (hereinafter referred to as second occupancy information for convenience of description) according to the first occupancy information, and process services supported by the UMTS NodeB in the second occupancy information.

Then, the LTE eNodeB and the UMTS NodeB may send the baseband signal processed by the radio frequency module at the TTI time according to the respective spectrum resource information.

It should be noted that, in practical application, because there is a certain time delay between the base station encoding and modulating signals, in this embodiment, the time difference between the time point when the second base station sends the occupation information to the first base station and the time point when the second base station sends the signals occupying the spectrum resource may be the time length of the time delay. For example, for the LTE eNodeB shown in fig. 6, it may be that the required occupied spectrum resource information (i.e. the first occupied information) is sent to the UMTS NodeB at the time of TTIi- σ and ttii+1-etc., and the time delay generated by the process of sending the spectrum resource information to the signal in the LTE eNodeB is σ, then the time points when the LTE eNodeB actually occupies the spectrum resource to send the signal are TTIi (i.e. TTIi- σ+σ) and ttii+1 (i.e. ttii+1- σ+σ). Similarly, since the first occupancy information also has a certain delay when transmitted from the LTE eNodeB to the UMTS NodeB, assuming ζ (0 < < σ), for the UMTS NodeB, the time points when it receives the spectrum resource information occupied by the LTE eNodeB are respectively TTIi- σ+ζ and ttii+1- σ+ζ, and the delay generated by the process from the UMTS NodeB receiving the spectrum resource information to transmitting the signal is σ -, the time point when the UMTS NodeB transmits the signal based on the second occupancy information is also TTIi (i.e., TTIi- σ+ζ+σ+σ - ζ) and ttii+1 (i.e., ttii+1- σ+ζ+σ - ζ). In this way, the time domain and frequency domain positions of signals can be precisely aligned between the LTE eNodeB and the UMTS NodeB, so that the signals can be transmitted conveniently. The occupation situations of the LTE eNodeB and the UMTS NodeB on the spectrum resources at the time TTIi and ttii+1 are shown in the right part of fig. 6.

Further, in practical applications, the first base station may refuse to continue sharing the unshared spectrum resources to the second base station, for example, when the first base station currently has an online voice service or a real-time data transmission service, the first base station needs to occupy the unshared spectrum resources to process the service, at this time, the first base station may generate, according to a second operation state of the second base station, stop sharing information for the unshared spectrum resources of the first base station, where the stop sharing information characterizes that the second base station cannot share the unshared spectrum resources of the first base station, and send the stop sharing information to the second base station. Thus, the second base station stops occupying the exclusive spectrum resource of the first base station after receiving the stopping sharing information.

Of course, in a further possible embodiment, the first base station may also continue to reclaim the shared spectrum resources of the first base station. For example, if the service to be processed by the first base station increases, the load of the first base station increases, and the first base station needs to occupy more spectrum resources, the first base station may also stop sharing the shared spectrum resources of the first base station and notify the second base station of the shared spectrum resources, so that the first base station can occupy the shared spectrum resources and is not affected by the second base station.

In this embodiment, when the first base station does not process the target service or is in the uplink and downlink compressed mode, the second base station may occupy all spectrum resources of the first base station, which increases spectrum resources of the second base station, further relieves the problem of shortage of spectrum resources of the second base station, and the second base station may enjoy complete bandwidth gain.
