技术领域technical field
本申请涉及通信技术领域，尤其涉及一种室内无源***和有源***同频组网的频谱共享方法及***。The present application relates to the field of communication technologies, and in particular, to a spectrum sharing method and system for co-frequency networking of an indoor passive system and an active system.
背景技术Background technique
在全球范围内，移动通信已经得到了飞速的发展和普及，无线网络也已经覆盖了绝大部分的区域，满足人们的需求和丰富人们的生活。由于绝大多数无线基站都部署在室外，受无线信号传播能力的影响，无线信号在室内的覆盖效果普遍差于室外，室内环境始终是用户投诉的主要地点。On a global scale, mobile communication has been rapidly developed and popularized, and wireless networks have covered most areas, meeting people's needs and enriching people's lives. Because the vast majority of wireless base stations are deployed outdoors, affected by the ability of wireless signal propagation, the coverage of wireless signals indoors is generally worse than outdoors, and the indoor environment is always the main place for user complaints.
移动宽带业务(Mobile Broadband,MBB)的发展带动了数据业务需求的急剧上升。数据业务往往更多来自室内环境。在这种趋势下，无线网络在室内覆盖效果比较差的问题加剧了改善和提升室内环境下无线网络质量和容量的需求。对于大型室内场景，如机场、体育馆等，一方面室外基站站址获取也很困难，另一方面即使部署了室外基站，由于室内建筑面积大、环境复杂、隔断多等，导致无线信号传播衰减严重，不能很好解决室内场景的移动通信覆盖和容量需求。The development of Mobile Broadband (MBB) has led to a sharp rise in the demand for data services. Data services tend to come more from indoor environments. Under this trend, the problem of poor indoor coverage of wireless networks has exacerbated the need to improve and enhance the quality and capacity of wireless networks in indoor environments. For large indoor scenarios, such as airports, gymnasiums, etc., on the one hand, it is difficult to obtain the site of the outdoor base station. , it cannot well solve the mobile communication coverage and capacity requirements of indoor scenarios.
针对室内覆盖效果较差的痛点，运营商在3G/4G时代就已开始部署室内无源***，例如分布式天线***(Distributed Antenna System,DAS)。DAS的典型拓扑如图1所示。经过不断改造，当前的DAS普遍可以支持2.6GHz频段，因此拥有2.6GHz新无线(New Radio,NR)或2.6GHz以下频段的运营商可以采用NR射频拉远单元(Remote Radio Unit,RRU)直接馈入，快速解决室内NR覆盖问题，无需前端的改造，成本相对来说也比较低。In response to the pain point of poor indoor coverage, operators have begun to deploy indoor passive systems in the 3G/4G era, such as Distributed Antenna System (DAS). A typical topology of DAS is shown in Figure 1. After continuous transformation, the current DAS can generally support the 2.6GHz frequency band, so operators with 2.6GHz New Radio (NR) or frequency bands below 2.6GHz can use NR Remote Radio Unit (RRU) to directly feed It can quickly solve the indoor NR coverage problem, without the need for front-end transformation, and the cost is relatively low.
但传统的无源***存在容量受限以及体验相对较差的问题，无法满足一些特定场景或者局部区域的容量诉求。业界主流蜂窝设备厂家如华为、中兴、爱立信等都推出了自己的有源***解决方案。将数字中频或基带信号通过光纤或以太网网线数字化拉远，在有源头端做数字化处理后收发无线RF信号，实现数字化室分。例如：华为LampSite。However, traditional passive systems have the problems of limited capacity and relatively poor experience, and cannot meet the capacity requirements of some specific scenarios or local areas. The mainstream cellular equipment manufacturers in the industry, such as Huawei, ZTE, and Ericsson, have all launched their own active system solutions. The digital intermediate frequency or baseband signal is digitally extended through optical fiber or Ethernet network cable, and the wireless RF signal is sent and received after digital processing at the active head end to realize digital room division. For example: Huawei LampSite.
对于一些建设了无源***的楼宇，通过NR RRU直接馈入可能已经解决了整个楼宇的NR覆盖问题。通过在局部楼层或者局部区域叠加有源***，可以解决这些局部楼层或者局部区域的容量问题。图2为DAS与数字化室分***叠加的示意图。然而运营商的NR频谱相对比较有限，这就可能导致NR DAS和叠加的NR数字化室分***重叠覆盖后互相干扰问题。为了进一步解决干扰问题，可以采用以下两种技术方案：For some buildings with passive systems, direct feed through NR RRU may have solved the problem of NR coverage of the whole building. By superimposing active systems on local floors or local areas, the capacity problems of these local floors or local areas can be solved. Figure 2 is a schematic diagram of the superposition of DAS and the digital room sub-system. However, the operator's NR spectrum is relatively limited, which may lead to the problem of mutual interference after the overlapping coverage of the NR DAS and the superimposed NR digital room sub-system. In order to further solve the interference problem, the following two technical solutions can be adopted:
1、无源***和有源***异频组网：例如，2.6GHz的无源***和4.9GHz的有源***重叠组网。1. Inter-frequency networking between passive systems and active systems: For example, the 2.6GHz passive system and the 4.9GHz active system overlap.
2、固定频谱划分：例如移动2.6GHz有160MHz的带宽，无源***馈入采用前100MHz，叠加建设的有源***采用后60MHz。使无源***和有源***频点相互错开，避免干扰。2. Fixed spectrum division: For example, the mobile 2.6GHz has a bandwidth of 160MHz, the passive system feeds into the first 100MHz, and the superimposed active system adopts the last 60MHz. The frequency points of the passive system and the active system are staggered to avoid interference.
以上两种技术方案尽管能够避免无源***和有源***间的干扰，但是组网的频谱资源无法得到充分的利用，并且在一些无源***和有源***的负荷不均或者负荷变化较大的场景下，难以保证用户的通信体验。Although the above two technical solutions can avoid the interference between passive systems and active systems, the spectrum resources of the networking cannot be fully utilized, and in some passive systems and active systems, the load is uneven or the load changes greatly. In such a scenario, it is difficult to guarantee the user's communication experience.

具体实施方式Detailed ways
基于前文的介绍，在无源***与有源***重叠组网时，存在通信干扰的问题。为解决此问题，采用的例如异频组网，或者同频组网时固定频谱划分错开频点的技术方案，尽管能够在一定程度上解除干扰问题，但是无法最大化利用频谱资源，导致了频谱资源的浪费。此外，上述两种技术方案很难在无源***和有源***负荷不均或者负荷变化较大的场景下保证用户的通信体验。Based on the previous introduction, when the passive system and the active system overlap in the networking, there is a problem of communication interference. In order to solve this problem, the technical solutions such as inter-frequency networking, or the fixed frequency division and staggered frequency points in the same-frequency networking are adopted. Although the interference problem can be relieved to a certain extent, it cannot maximize the use of spectrum resources, resulting in the loss of frequency spectrum. waste of resources. In addition, it is difficult for the above two technical solutions to ensure a user's communication experience in a scenario where the passive system and the active system have uneven loads or large load changes.
例如，移动2.6GHz有160MHz的带宽，无源***馈入采用前100MHz，叠加建设的有源***采用后60MHz。在负荷不均的场景下，有源***的负荷较大而无源***的负荷较小，160MHz的带宽中后60MHz对于有源***来说已然不足，而前100MHz对于无源***来说 绰绰有余。此时，因为后60MHz带宽的限制，接入有源***的用户设备的业务请求则不得不延迟处理，导致用户体验下降。此外，无源***的负荷以及有源***的负荷往往是随着时间变化的。例如，t1时间上述的固定频谱划分方式能够满足两个***各自的需求，但是在t2时间，无源***的负荷降低且有源***的负荷激增，则影响到用户的通信体验。For example, the mobile 2.6GHz has a bandwidth of 160MHz, the passive system feeds the first 100MHz, and the active system constructed by superposition adopts the latter 60MHz. In the case of uneven load, the load of the active system is large and the load of the passive system is small. The last 60MHz of the 160MHz bandwidth is insufficient for the active system, while the first 100MHz is more than enough for the passive system. At this time, due to the limitation of the bandwidth of the last 60 MHz, the service request of the user equipment accessing the active system has to be processed with a delay, resulting in degraded user experience. Furthermore, the loads of passive systems as well as the loads of active systems tend to vary over time. For example, the above-mentioned fixed spectrum division method at time t1 can meet the respective requirements of the two systems, but at time t2, the load of the passive system decreases and the load of the active system surges, which affects the user's communication experience.
为了解决频谱效率低，用户通信体验不佳的问题，发明人经过研究，于本申请中提供了一种室内无源***和有源***同频组网的频谱共享方法及同频组网通信***。以下结合实施例和附图对该方法和该通信***的具体实现方式分别进行说明。In order to solve the problems of low spectral efficiency and poor user communication experience, the inventors have researched and provided a spectrum sharing method for co-frequency networking of indoor passive systems and active systems and a co-frequency networking communication system in this application. . Specific implementations of the method and the communication system will be described below with reference to the embodiments and the accompanying drawings.
无源***和有源***的组网形式可以参照图2。在介绍室内无源***和有源***同频组网的频谱共享方法之前，首先对本申请实施例中的带宽配置进行介绍和说明。The networking forms of the passive system and the active system can refer to FIG. 2 . Before introducing a spectrum sharing method for intra-frequency networking of an indoor passive system and an active system, the bandwidth configuration in the embodiment of the present application is first introduced and described.
在本申请实施例中，同频组网的无源***和有源***均支持目标频段。在目标频段对应的目标带宽中，前第一带宽被配置为无源***的私有带宽，后第二带宽被配置为有源***的私有带宽，目标带宽中第一带宽和第二带宽之间的带宽被配置为无源***与有源***的共享带宽。In the embodiment of the present application, both the passive system and the active system in the same-frequency networking support the target frequency band. In the target bandwidth corresponding to the target frequency band, the former first bandwidth is configured as the private bandwidth of the passive system, the latter second bandwidth is configured as the private bandwidth of the active system, and the difference between the first bandwidth and the second bandwidth in the target bandwidth is The bandwidth is configured as the shared bandwidth of the passive system and the active system.
作为示例，目标频段为2.6GHz，其对应的目标带宽从2515MHz至2675MHz。图3为本申请实施例提供的一种为室内无源***和有源***同频组网配置带宽的示意图。如图3所示，第一带宽从2515MHz至2575MHz；共享带宽从2575MHz至2615MHz；第二带宽从2615MHz至2675MHz。As an example, the target frequency band is 2.6GHz, which corresponds to a target bandwidth from 2515MHz to 2675MHz. FIG. 3 is a schematic diagram of configuring a bandwidth for intra-frequency networking of an indoor passive system and an active system according to an embodiment of the present application. As shown in FIG. 3 , the first bandwidth is from 2515MHz to 2575MHz; the shared bandwidth is from 2575MHz to 2615MHz; and the second bandwidth is from 2615MHz to 2675MHz.
当然，本申请实施例提供的室内无源***和有源***同频组网的频谱共享方法还可以适用于其他目标频段的同频组网中。例如，2.1GHz的目标频段。图3仅为示例，此处对于目标频段和目标带宽不做限制。Of course, the spectrum sharing method for intra-frequency networking of an indoor passive system and an active system provided in the embodiment of the present application can also be applied to the same-frequency networking of other target frequency bands. For example, the target frequency band of 2.1GHz. FIG. 3 is only an example, and the target frequency band and target bandwidth are not limited here.
有源***的通道数量通常大于或等于无源***的通道数量。例如，无源***采用1T1R(表示无源***包括1个发送通道和1个接收通道)，有源***采用4T4R(表示有源***包括4个发送通道和4个接收通道)。通常来说，有源***发送和接收信号的强度要高于无源***发送和接收信号的强度。比起前文提到的当前固定频谱划分的方案，图3示例中在无源***(固定分配100MHz)的一侧设置共享带宽，为有源***包括私有的60MHz第二带宽，从而保障有源***具有较充足的保底带宽。The number of channels in active systems is usually greater than or equal to the number of channels in passive systems. For example, the passive system adopts 1T1R (meaning that the passive system includes 1 transmitting channel and 1 receiving channel), and the active system adopts 4T4R (meaning that the active system includes 4 transmitting channels and 4 receiving channels). In general, the strength of the signal transmitted and received by an active system is higher than that of a passive system. Compared with the current fixed spectrum allocation scheme mentioned above, in the example of Figure 3, a shared bandwidth is set on one side of the passive system (fixed allocation of 100MHz), and a private 60MHz second bandwidth is included for the active system, thereby ensuring the active system. It has sufficient guaranteed bandwidth.
在图3示例中，第一带宽60MHz，共享带宽40MHz，第二带宽60MHz。第一带宽与共享带宽之和大于第二带宽。第一带宽及第二带宽均大于共享带宽。第一带宽等于第二带宽。图3的带宽配置方式仅为示例，数值不作为对带宽配置的限制。例如，还可以配置第一带宽50MHz，共享带宽50MHz，第二带宽60MHz。为第一带宽、第二带宽和共享带宽的配置方案可以根据实际需求进行设置。In the example of FIG. 3 , the first bandwidth is 60MHz, the shared bandwidth is 40MHz, and the second bandwidth is 60MHz. The sum of the first bandwidth and the shared bandwidth is greater than the second bandwidth. Both the first bandwidth and the second bandwidth are greater than the shared bandwidth. The first bandwidth is equal to the second bandwidth. The bandwidth configuration method in FIG. 3 is only an example, and the numerical value is not used as a limitation on the bandwidth configuration. For example, it is also possible to configure the first bandwidth of 50MHz, the shared bandwidth of 50MHz, and the second bandwidth of 60MHz. The configuration schemes for the first bandwidth, the second bandwidth and the shared bandwidth can be set according to actual requirements.
以上介绍了对目标带宽的配置方式。下面结合附图和实施例介绍频谱共享方法。图4为本申请实施例提供的一种室内无源***和有源***同频组网的频谱共享方法流程图。如图4所示，该方法包括：The above describes how to configure the target bandwidth. The following describes a spectrum sharing method with reference to the accompanying drawings and embodiments. FIG. 4 is a flowchart of a spectrum sharing method for intra-frequency networking of an indoor passive system and an active system according to an embodiment of the present application. As shown in Figure 4, the method includes:
步骤401：确定用户设备在所述同频组网中接入的***，当确定用户设备在所述同频组网中接入的***为所述无源***时，执行步骤402；当确定用户设备在所述同频组网中接入的***为所述有源***时，执行步骤403。Step 401: Determine the system that the user equipment accesses in the intra-frequency networking, when it is determined that the system that the user equipment accesses in the intra-frequency networking is the passive system, perform step 402; When the system accessed by the device in the intra-frequency networking is the active system, step 403 is performed.
本申请实施例提供的技术方案中，同频组网包括：无源***和有源***。作为示例，无源***可以包括传统的DAS；有源***可以包括数字化室分***，例如华为LampSite。此处对于无源***及有源***各自的具体组成不做限制。In the technical solutions provided by the embodiments of the present application, the intra-frequency networking includes: a passive system and an active system. As an example, passive systems may include traditional DAS; active systems may include digital room subsystems, such as Huawei LampSite. The specific composition of the passive system and the active system is not limited here.
在同一时间，一个用户设备仅能接入无源***和有源***二者之一，并由接入的***来处理用户设备发送的业务请求。在本步骤的一种可能的实现方式中，可以通过用户设备确定其接入的***。在另一种可能的实现方式中，可以通过包含无源***和有源***的同频组网确定用户设备接入的***。At the same time, a user equipment can only access one of the passive system and the active system, and the accessed system processes the service request sent by the user equipment. In a possible implementation manner of this step, the system to which the user equipment accesses may be determined by the user equipment. In another possible implementation manner, the system to be accessed by the user equipment may be determined through a co-frequency networking including a passive system and an active system.
步骤402：无源***利用所述第一带宽和/或所述共享带宽处理接入到所述无源***的用户设备的业务。Step 402: The passive system uses the first bandwidth and/or the shared bandwidth to process services of the user equipment accessing the passive system.
由于第一带宽和共享带宽对于无源***均是可用的，因此，如果用户设备接入的***是无源***，则无源***可以自行将用户设备请求处理的业务分配到第一带宽或者共享带宽。此外，在一些实现场景中，如果用户设备请求处理的业务量较大、第一带宽剩余的空闲带宽或共享带宽中剩余的空闲带宽较少时，无源***也可以利用第一带宽和共享带宽共同处理接入到无源***的该用户设备的业务。Since both the first bandwidth and the shared bandwidth are available to the passive system, if the system accessed by the user equipment is a passive system, the passive system can allocate the service requested by the user equipment to the first bandwidth or the shared bandwidth by itself. bandwidth. In addition, in some implementation scenarios, if the amount of traffic requested to be processed by the user equipment is large, the remaining idle bandwidth of the first bandwidth or the remaining idle bandwidth of the shared bandwidth is small, the passive system can also utilize the first bandwidth and the shared bandwidth. The services of the user equipment connected to the passive system are jointly processed.
步骤403：有源***利用所述第二带宽和/或所述共享带宽处理接入到所述有源***的用户设备的业务。Step 403: The active system uses the second bandwidth and/or the shared bandwidth to process services of the user equipment accessing the active system.
由于第二带宽和共享带宽对于有源***均是可用的，因此，如果用户设备接入的***是有源***，则有源***可以自行将用户设备请求处理的业务分配到第二带宽或者共享带宽。此外，在一些实现场景中，如果用户设备请求处理的业务量较大、第二带宽剩余的空闲带宽或共享带宽中剩余的空闲带宽较少时，有源***也可以利用第二带宽和共享带宽共同处理接入到有源***的该用户设备的业务。Since both the second bandwidth and the shared bandwidth are available to the active system, if the system accessed by the user equipment is an active system, the active system can automatically allocate the service requested by the user equipment to the second bandwidth or share the bandwidth. In addition, in some implementation scenarios, if the amount of traffic requested by the user equipment is large, the remaining idle bandwidth of the second bandwidth or the remaining idle bandwidth of the shared bandwidth is small, the active system can also utilize the second bandwidth and the shared bandwidth. The traffic of the user equipment connected to the active system is jointly processed.
以上即为本申请实施例提供的室内无源***和有源***同频组网的频谱共享方法。在本申请提供的频谱共享方法中，无源***的业务不局限于在第一带宽上实现，有源***的业务也不局限于在第二带宽上实现。通过目标带宽中配置的共享带宽可以实现频谱资源共享，因此有效提升频谱效率。在一些无源***与有源***负荷不均或者负荷变化较大的场景下，通过带宽的共享也可以保障用户的通信体验。The above is the spectrum sharing method for intra-frequency networking of the indoor passive system and the active system provided by the embodiment of the present application. In the spectrum sharing method provided by the present application, the service of the passive system is not limited to be implemented on the first bandwidth, and the service of the active system is not limited to be implemented on the second bandwidth. Spectrum resource sharing can be achieved through the shared bandwidth configured in the target bandwidth, thus effectively improving spectrum efficiency. In some scenarios where the passive system and active system have uneven loads or large load changes, the sharing of bandwidth can also ensure the user's communication experience.
在本申请实施例提供的技术方案中，考虑到无源***及有源***各自负荷变化的场景，为了在负荷变化的场景下也能够最大化地利用频谱资源，本申请实施例提供的室内无源***和有源***同频组网的频谱共享方法还进一步包括步骤404-406，如图5所示：In the technical solutions provided by the embodiments of the present application, considering the scenarios of load changes of the passive system and the active system, in order to maximize the utilization of spectrum resources in the scenario of load changes, the indoor wireless wireless system provided by the embodiments of the present application The spectrum sharing method for co-frequency networking of the source system and the active system further includes steps 404-406, as shown in Figure 5:
步骤404：有源***和无源***相互发送自身对目标带宽的资源消耗信息。Step 404: The active system and the passive system send each other information on resource consumption of the target bandwidth.
图6为本申请实施例提供的一种有源***与无源***互发资源消耗信息的示意图。为便于区分，本申请实施例中将无源***发送的资源消耗信息称为第一资源消耗信息，将有源***发送的资源消耗信息称为第二资源消耗信息。通过本步骤的执行，有源***和无源***可以互知对方对目标带宽的资源消耗详情。FIG. 6 is a schematic diagram of an active system and a passive system sending resource consumption information to each other according to an embodiment of the present application. For convenience of distinction, in this embodiment of the present application, the resource consumption information sent by the passive system is referred to as the first resource consumption information, and the resource consumption information sent by the active system is referred to as the second resource consumption information. Through the execution of this step, the active system and the passive system can know each other's resource consumption details of the target bandwidth.
资源消耗信息可以包括：带宽占用量。还可以包括用户设备数量。The resource consumption information may include: bandwidth usage. The number of user devices may also be included.
例如，第一资源消耗信息包括：无源***对目标带宽中第一带宽和共享带宽的带宽占用量，还包括接入到无源***的用户设备的数量。无源***对目标带宽的带宽占用量越大， 表示无源***的频谱资源较为紧张；而无源***对目标带宽的带宽占用量越小，表示无源***的频谱资源较为空闲。第二资源消耗信息包括：有源***对目标带宽中第二带宽和共享带宽的带宽占用量，还包括接入到有源***的用户设备的数量。有源***对目标带宽的带宽占用量越大，表示有源***的频谱资源较为紧张；而有源***对目标带宽的带宽占用量越小，表示有源***的频谱资源较为空闲。For example, the first resource consumption information includes: the bandwidth occupancy of the first bandwidth and the shared bandwidth in the target bandwidth by the passive system, and also includes the number of user equipments accessing the passive system. The larger the bandwidth occupancy of the passive system on the target bandwidth, the more limited the passive system's spectrum resources; the smaller the passive system's bandwidth occupancy on the target bandwidth, the more idle the passive system's spectral resources. The second resource consumption information includes: the bandwidth occupancy of the second bandwidth and the shared bandwidth in the target bandwidth by the active system, and also includes the number of user equipments connected to the active system. The larger the active system's bandwidth occupancy of the target bandwidth, the more limited the active system's spectrum resources; and the smaller the active system's bandwidth occupancy of the target bandwidth, the more idle the active system's spectrum resources.
在一种可能的实现方式中，有源***和无源***相互发送自身对目标带宽的资源消耗信息的操作可以周期性地执行。例如，每隔10秒，有源***向无源***发送一次第二资源消耗信息；每隔10秒，无源***向有源***发送一次第一资源消耗信息。资源消耗信息的发送周期(或发送频率)可以根据实际需求进行设置，此外，发送周期(或发送频率)也可调节变化。In a possible implementation manner, the operation of the active system and the passive system sending each other resource consumption information of the target bandwidth may be performed periodically. For example, every 10 seconds, the active system sends the second resource consumption information to the passive system; every 10 seconds, the passive system sends the first resource consumption information to the active system. The sending cycle (or sending frequency) of the resource consumption information can be set according to actual needs, and in addition, the sending cycle (or sending frequency) can also be adjusted and changed.
在一些可能的实现方式中，资源消耗信息不局限于当前的资源消耗信息，还可以是历史的资源消耗信息或者根据历史的资源消耗信息预测出的资源消耗信息。作为示例，历史的资源消耗信息可以是过往的100个传输周期内实际的资源消耗信息，预测的资源消耗信息可以是根据过往的100个传输周期内实际的资源消耗信息预测出的当前传输周期的资源消耗信息。In some possible implementation manners, the resource consumption information is not limited to the current resource consumption information, but may also be historical resource consumption information or resource consumption information predicted according to the historical resource consumption information. As an example, the historical resource consumption information may be the actual resource consumption information in the past 100 transmission periods, and the predicted resource consumption information may be the current transmission period predicted according to the actual resource consumption information in the past 100 transmission periods Resource consumption information.
无源***对目标带宽的资源第一消耗信息，包括以下至少一种：无源***对目标带宽当前的资源第一消耗信息，无源***对目标带宽历史的资源第一消耗信息，或者无源***对目标带宽预测的资源第一消耗信息；无源***对目标带宽预测的资源第一消耗信息为依据无源***对目标带宽历史的资源第一消耗信息预测得到的。The first resource consumption information of the passive system on the target bandwidth, including at least one of the following: the current first resource consumption information of the passive system on the target bandwidth, the passive system's historical resource first consumption information on the target bandwidth, or the passive system's first resource consumption information on the target bandwidth. The first resource consumption information predicted by the system to the target bandwidth; the first resource consumption information predicted by the passive system to the target bandwidth is obtained by predicting the first resource consumption information of the target bandwidth history by the passive system.
有源***对目标带宽的资源第二消耗信息，包括以下至少一种：有源***对目标带宽当前的资源第二消耗信息，有源***对目标带宽历史的资源第二消耗信息，或者有源***对目标带宽预测的资源第二消耗信息；有源***对目标带宽预测的资源第二消耗信息为依据有源***对目标带宽历史的资源第二消耗信息预测得到的。The second resource consumption information of the active system on the target bandwidth, including at least one of the following: the current second resource consumption information on the target bandwidth by the active system, the historical second resource consumption information on the target bandwidth by the active system, or the active system's second resource consumption information on the target bandwidth. The second resource consumption information predicted by the system to the target bandwidth; the second resource consumption information predicted by the active system to the target bandwidth is obtained according to the second resource consumption information predicted by the active system to the target bandwidth history.
以无源***为例，如果无源***接收到的有源***对目标带宽的资源第二消耗信息仅包括有源***对目标带宽历史的资源消耗信息，则无源***可以依据有源***对目标带宽历史的资源消耗信息对有源***进行预测，获得有源***对目标带宽预测的资源消耗信息。此外，有源***对目标带宽预测的资源消耗信息也可以由有源***自行预测并发送给无源***。Taking the passive system as an example, if the second resource consumption information of the active system to the target bandwidth received by the passive system only includes the historical resource consumption information of the active system to the target bandwidth, then the passive system can The resource consumption information of the target bandwidth history is used to predict the active system, and the resource consumption information of the active system to predict the target bandwidth is obtained. In addition, the resource consumption information predicted by the active system to the target bandwidth can also be predicted by the active system and sent to the passive system.
步骤405：无源***根据自身对目标带宽的资源消耗和/或有源***对目标带宽的资源消耗信息，配置自身对共享带宽的可用性。Step 405: The passive system configures its own availability to the shared bandwidth according to its own resource consumption of the target bandwidth and/or the resource consumption information of the active system to the target bandwidth.
由于无源***已知自身对目标带宽的资源消耗(即第一资源消耗信息)，并通过步骤404获得了第二资源消耗信息，因此，可以依据第一资源消耗信息，依据第二资源消耗信息，或者结合依据第一资源消耗信息和第二资源消耗信息来配置自身对共享带宽的可用性。Since the passive system knows its own resource consumption of the target bandwidth (ie, the first resource consumption information), and obtains the second resource consumption information through step 404, therefore, according to the first resource consumption information, according to the second resource consumption information , or configure its own availability to the shared bandwidth according to the first resource consumption information and the second resource consumption information.
下面介绍无源***依据第一资源消耗信息来配置自身对共享带宽的可用性的实现方式。The following describes an implementation manner in which the passive system configures its own availability to the shared bandwidth according to the first resource consumption information.
当无源***对目标带宽的带宽占用量小于或等于第一门限值时，表示无源***的频谱资源空闲，此时，无源***可以配置无源***不可使用共享带宽。如此，共享带宽可以最大程度地被有源***使用。图7为无源***对共享带宽不可用时，无源***和有源***各 自可使用的带宽示意图。如图7所示，此时，无源***仅可使用目标带宽中的第一带宽，而有源***则可以使用全部的共享带宽和第二带宽。如此，提升了有源***的用户的业务体验。当无源***对目标带宽的带宽占用量大于第二门限值(第二门限值大于或等于第一门限值)时，表示无源***的频谱资源紧张，此时，无源***可以配置无源***可使用共享带宽，即允许无源***使用共享带宽。如此，无源***需要处理的一部分业务可以在共享带宽上实现。When the bandwidth occupancy of the target bandwidth by the passive system is less than or equal to the first threshold value, it indicates that the passive system has idle spectrum resources. At this time, the passive system can configure that the passive system cannot use the shared bandwidth. In this way, the shared bandwidth can be used to the maximum extent by the active system. Figure 7 is a schematic diagram of the bandwidth available to the passive system and the active system when the shared bandwidth is not available for the passive system. As shown in FIG. 7 , at this time, the passive system can only use the first bandwidth among the target bandwidths, while the active system can use the entire shared bandwidth and the second bandwidth. In this way, the service experience of the user of the active system is improved. When the bandwidth occupancy of the target bandwidth by the passive system is greater than the second threshold value (the second threshold value is greater than or equal to the first threshold value), it indicates that the spectrum resources of the passive system are tight, and at this time, the passive system can Configuring passive systems to use shared bandwidth allows passive systems to use shared bandwidth. In this way, a part of the business that the passive system needs to handle can be implemented on the shared bandwidth.
下面还提供一种无源***综合依据第一资源消耗信息和第二资源消耗信息来配置自身对共享带宽的可用性的实现方式。The following also provides an implementation manner in which the passive system comprehensively configures its own availability to the shared bandwidth according to the first resource consumption information and the second resource consumption information.
例如，无源***对目标带宽的带宽占用量小于或等于第一门限值时，还需要进一步判断有源***对目标带宽的带宽占用量是否超过第三门限值，如果是，则无源***可以配置无源***不可使用共享带宽，否则，不切换无源***对共享带宽的可用性。无源***对目标带宽的占用量大于第二门限值时，还需要进一步判断有源***对目标带宽的带宽占用量是否小于第四门限值，如果是，则无源***可以配置无源***可使用共享带宽，否则，不切换无源***对共享带宽的可用性。For example, when the bandwidth occupancy of the target bandwidth by the passive system is less than or equal to the first threshold value, it is necessary to further determine whether the bandwidth occupancy of the target bandwidth by the active system exceeds the third threshold value. The system can configure that the passive system cannot use the shared bandwidth, otherwise, the availability of the passive system to the shared bandwidth will not be switched. When the occupancy of the target bandwidth by the passive system is greater than the second threshold, it is necessary to further determine whether the bandwidth occupancy of the target bandwidth by the active system is less than the fourth threshold. If so, the passive system can be configured with a passive system. The system can use the shared bandwidth, otherwise, the passive system's availability to the shared bandwidth is not switched.
在其他可能的实现方式中，无源***还可以根据未来一段时间内无源***和有源***分别对频谱资源的占用情况配置自身对共享带宽的可用性。In other possible implementation manners, the passive system may also configure its own availability to the shared bandwidth according to the occupation of spectrum resources by the passive system and the active system respectively in the future.
例如，当预测未来一段时间(时间长度可以根据实际需求设置)内，无源***对目标带宽的带宽占用量小于或等于第一门限值，且有源***对目标带宽的带宽占用量超过第三门限值，则无源***可以配置无源***不可使用共享带宽。当预测未来一段时间内无源***对目标带宽的占用量大于第二门限值，且有源***对目标带宽的带宽占用量小于第四门限值时，无源***可以配置无源***可使用共享带宽。For example, when predicting a future period of time (the time length can be set according to actual needs), the bandwidth occupancy of the target bandwidth by the passive system is less than or equal to the first threshold value, and the bandwidth occupancy of the target bandwidth by the active system exceeds the first threshold. With three thresholds, the passive system can configure the passive system and cannot use the shared bandwidth. When it is predicted that the occupancy of the target bandwidth by the passive system in the future is greater than the second threshold value, and the bandwidth occupancy of the target bandwidth by the active system is less than the fourth threshold value, the passive system can configure the passive system to Use shared bandwidth.
下面再提供一种无源***综合依据第二资源消耗信息来配置自身对共享带宽的可用性的实现方式。The following further provides an implementation manner in which the passive system comprehensively configures its own availability to the shared bandwidth according to the second resource consumption information.
当第二资源消耗信息指示有源***对目标带宽的带宽占用量超过第五门限值时，表示有源***的频谱资源紧张，无源***可以配置自身对共享带宽不可用，使得有源***能够尽可能多地使用到共享带宽。当第二资源消耗信息指示有源***对目标带宽的带宽占用量低于第六门限值(第六门限值小于或等于第五门限值)时，表示有源***的频谱资源是相对充裕的，不需要无源***让出所有的共享带宽，因此，无源***可以配置自身对共享带宽可用。When the second resource consumption information indicates that the bandwidth occupancy of the target bandwidth by the active system exceeds the fifth threshold value, it indicates that the spectrum resources of the active system are tight, and the passive system can configure itself to be unavailable for the shared bandwidth, so that the active system can Use as much shared bandwidth as possible. When the second resource consumption information indicates that the bandwidth occupancy of the target bandwidth by the active system is lower than the sixth threshold value (the sixth threshold value is less than or equal to the fifth threshold value), it indicates that the spectrum resources of the active system are relatively Abundant, passive systems are not required to give up all shared bandwidth, so passive systems can configure themselves to be available for shared bandwidth.
需要说明的是，第一门限值、第二门限值、第三门限值、第四门限值、第五门限值以及第六门限值的具体取值可以根据实际场景、实际需求来设定。此处不对数值进行限定。It should be noted that the specific values of the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the fifth threshold value and the sixth threshold value may needs to be set. The numerical value is not limited here.
除了配置共享带宽的可用性以外，无源***还可以通过分配和调度业务提升对频谱资源的利用率或者降低对共享带宽的带宽占用量。例如，当无源***对目标带宽的带宽占用量小于或等于第一门限值时，无源***将原分配至共享带宽的无源***的一部分或全部业务调度至第一带宽，此时节省出来的共享带宽可以更大程度上地由有源***使用。当无源***对目标带宽的带宽占用量大于第二门限值时，无源***也可以将原分配至第一带宽的一部分无源***的业务调度给共享带宽。In addition to configuring the availability of the shared bandwidth, passive systems can also improve the utilization of spectrum resources or reduce the bandwidth occupancy of the shared bandwidth by allocating and scheduling services. For example, when the bandwidth occupancy of the target bandwidth by the passive system is less than or equal to the first threshold value, the passive system schedules a part or all of the services originally allocated to the passive system that shared the bandwidth to the first bandwidth, saving savings at this time. The shared bandwidth that comes out can be used by active systems to a greater extent. When the bandwidth occupancy of the target bandwidth by the passive system is greater than the second threshold value, the passive system may also schedule a part of the services of the passive system originally allocated to the first bandwidth to the shared bandwidth.
通常情况下，鉴于有源***接收和发送信号的强度相比于无源***接收和发送信号的强度更强，有源***配置始终对共享带宽可用。但是考虑到无源***也可能存在负荷激增，需要处理大量业务的情况，因此，在本申请实施例中，有源***对于共享带宽的可用性也是可以自由配置的，如以下步骤406。Typically, active system configurations are always available for shared bandwidth, given that active systems receive and transmit signals at a higher strength than passive systems. However, considering that the passive system may also have a surge in load and needs to process a large number of services, in this embodiment of the present application, the availability of the shared bandwidth for the active system can also be freely configured, as shown in step 406 below.
步骤406：有源***根据自身对目标带宽的资源消耗和/或无源***对目标带宽的资源消耗信息，配置自身对共享带宽的可用性。Step 406: The active system configures its own availability to the shared bandwidth according to its resource consumption of the target bandwidth and/or the resource consumption information of the passive system to the target bandwidth.
与步骤405中的无源***类似地，有源***也可以在已知自身对目标带宽的资源消耗(即第二资源消耗信息)，并通过步骤404获得了第一资源消耗信息的前提下，依据第一资源消耗信息，依据第二资源消耗信息，或者结合依据第一资源消耗信息和第二资源消耗信息来配置自身对共享带宽的可用性。本步骤的相关实现方式可以参照步骤405，此处不再赘述。此外，有源***也可以通过调度业务来降低对共享带宽的占用，或者将业务分担到共享带宽。Similar to the passive system in step 405, the active system can also know the resource consumption of the target bandwidth (that is, the second resource consumption information) and obtain the first resource consumption information through step 404. The availability of the shared bandwidth is configured according to the first resource consumption information, the second resource consumption information, or a combination of the first resource consumption information and the second resource consumption information. For the related implementation of this step, reference may be made to step 405, which will not be repeated here. In addition, the active system can also reduce the occupation of the shared bandwidth by scheduling services, or share services to the shared bandwidth.
在以上实施例中，无源***和有源***依据互相发送的资源消耗信息，实现自身对共享带宽可用性的配置。如此，在无源***及有源***的负荷不均，或者各自负荷变化的场景下，可以通过配置(或切换)对共享带宽可用或不可用，动态共享频谱资源。从而，最大化地利用频谱资源，提升频谱效率。In the above embodiments, the passive system and the active system implement their own configuration of the shared bandwidth availability according to the resource consumption information sent to each other. In this way, in a scenario where the loads of the passive system and the active system are uneven, or the respective loads change, the shared bandwidth can be made available or unavailable through configuration (or switching), and spectrum resources can be dynamically shared. Thus, spectrum resources are maximized and spectrum efficiency is improved.
以上实施例中，资源消耗信息中的带宽占用量作为动态实现频谱资源共享的主要依据。当然，在其他实现方式中，也可以结合接入无源***的用户设备数量和/或接入有关***的用户设备数量实现对共享带宽可用性的配置决策。In the above embodiments, the bandwidth occupancy in the resource consumption information is used as the main basis for dynamically implementing spectrum resource sharing. Of course, in other implementation manners, the configuration decision on the availability of the shared bandwidth may also be implemented in combination with the number of user equipments accessing the passive system and/or the number of user equipments accessing the related system.
为了尽量减少无源***用户设备对频谱资源的消耗，从而使有源***的用户设备能够更大几率地占用共享带宽，可以配置有源***较高的频点驻留优先级，配置无源***较低的频点驻留优先级。如此一来，用户设备能够优先接入到有源***，有机会在共享带宽上体验业务服务。In order to minimize the consumption of spectrum resources by the user equipment of the passive system, so that the user equipment of the active system can occupy the shared bandwidth with a greater probability, you can configure the active system with a higher frequency station priority, and configure the passive system Lower frequencies have priority to park. In this way, the user equipment can preferentially access the active system and have the opportunity to experience business services on the shared bandwidth.
基于前述实施例提供的室内无源***和有源***同频组网的频谱共享方法，相应地，本申请还提供一种同频组网通信***。该通信***的布局可以参照图2。Based on the spectrum sharing method for co-frequency networking of an indoor passive system and an active system provided by the foregoing embodiments, correspondingly, the present application also provides a co-frequency networking communication system. The layout of the communication system can be referred to FIG. 2 .

Two bandwidths and/or shared bandwidths handle traffic for user equipment accessing the active system.
在本申请提供的技术方案中，无源***的业务不局限于在第一带宽上实现，有源***的业务也不局限于在第二带宽上实现。通过目标带宽中配置的共享带宽可以实现频谱资源共享，因此有效提升频谱效率。在一些无源***与有源***负荷不均或者负荷变化较大的场景下，通过带宽的共享也可以保障用户的通信体验。In the technical solution provided by the present application, the services of the passive system are not limited to be implemented on the first bandwidth, and the services of the active system are not limited to be implemented on the second bandwidth. Spectrum resource sharing can be achieved through the shared bandwidth configured in the target bandwidth, thus effectively improving spectrum efficiency. In some scenarios where the passive system and active system have uneven loads or large load changes, the sharing of bandwidth can also ensure the user's communication experience.
