Description

一种支持频谱资源共享的无线资源分配方法 That supports spectrum resources shared wireless resource allocation method

技术领域 FIELD

[0001] 本发明涉及无线通信系统的无线资源分配技术,特别是涉及支持频谱资源共享的异构网络的无线资源分配方法。 [0001] The present invention relates to a wireless communication system, a radio resource assignment technology, particularly to support the sharing of spectrum resources of a heterogeneous network radio resource allocation method.

背景技术 Background technique

[0002] 多网络融合的异构网络和泛在移动性将是下一代网络的主要特点,无线资源稀缺、带宽的限制和无线信道的时变特性成为网络传输性能的主要瓶颈,提高异构网络的频谱利用率成为一个主要目标。 [0002] heterogeneous network multi-network convergence and mobility will pan the main features of the next generation network, radio resources are scarce, and limits the bandwidth of the wireless channel becomes the bottleneck of network transmission characteristics as the main performance, improved heterogeneous network spectrum efficiency as a major goal. 随着无线应用的日益增多,静态的频谱规划体制阻碍了无线频谱资源利用率的提升,一方面适宜无线通信的频谱资源十分稀缺,另一方面又浪费严重。 With the increasing number of wireless applications, static spectrum planning system hinders the wireless spectrum to enhance resource utilization, on the one hand suitable for wireless communication spectrum resources are scarce, on the other hand wasted. 为此,需要改变静态的频谱规划体制,采用动态的频谱规划体制以支持频谱资源共享,开发频谱资源共享的无线通信系统以弥补资源的不足。 To do this, we need to change the static spectrum planning system, dynamic spectrum planning system to support the sharing of spectrum resources, the development of spectrum resources shared wireless communications system to make up for lack of resources. 目前的无线通信系统逐步引入或者已实现了软件无线电(SDR)、感知无线电(CR),这些技术为动态频谱规划应用得以实现提供了技术保证;开放式频谱管理思想允许用户能够感知本地可用无线资源,并能够按照一定分配算法使用这些无线资源。 Current wireless communication systems gradually introduced or have implemented software-defined radio (SDR), cognitive radio (CR), these technologies provide a technical guarantee for dynamic spectrum planning application can be achieved; open spectrum management thinking allows the user to perceive locally available wireless resources and be able to use these wireless resources according to certain allocation algorithm.

[0003] 因此,为了满足异构网络通讯需求,需要在兼容当前已有频谱分配体制的前提下, 引入更加灵活有效的动态频谱分配策略,从而最大程度的提高频谱的整体利用率;进一步, 引入合理的资源分配算法对网络中的无线资源进行动态分配,提升网络资源的利用率,从而为网络中的各个用户提供服务质量(QoS)保障。 [0003] Therefore, in order to meet the communications needs of a heterogeneous network, you need to have the premise compatible with the current spectrum allocation system, the introduction of more flexible and efficient dynamic spectrum allocation policy in order to maximize the overall utilization rate of the spectrum; further, introducing rational resource allocation algorithm in the network radio resources dynamically allocated to enhance the utilization of network resources to provide quality of service (QoS) for the network, each user protection.

[0004] 采用动态的频谱规划体制,以支持异构网络频谱资源共享,就需要在更细分的尺度上实现无线资源动态分配;同时,无线资源具备时间特性、频率特性、能量特性、空间特性等多维特性。 [0004] dynamic spectrum planning system to support heterogeneous network spectrum resource sharing, we need to realize dynamic radio resource allocation in a more subdivision of scale; at the same time, the radio resource properties with time, frequency, energy characteristics, spatial characteristics and other multidimensional characteristics. 因此,在对系统掌握的无线资源进行划分的时候,可以从多维度的角度最优化分配无线资源;其次,无线资源的最终分配结果不但要能够和无线网络拥有的物理资源传输能力相匹配,还要能够和网络的业务需求(如QoS需求,公平性,资源需求量)相匹配;最后,异构网络无线资源的分配必须控制网络中不同通信系统所拥有资源之间的相互干扰。 Therefore, when the system control radio resources division, can be optimized from a multi-dimensional perspective of allocation of radio resources; secondly, the final allocation of the results of radio resources not only to be able to match the physical resources of the transmission capacity of wireless networks has also to be able to match the network's service requirements (e.g. QoS requirements, fairness, resource requirements); and finally, the radio resource allocation heterogeneous network control network must be mutual interference between different communication systems have the resources.

发明内容 SUMMARY

[0005] 本发明所要解决的技术问题是:解决无线频谱资源动态规划的问题,支持异构网络的频谱资源共享;提供一种具备多维度特性的无线资源动态分配方法,支持异构网络的不同模式的控制机制。 [0005] The present invention solves the technical problem are: to solve the problem of dynamic programming radio spectrum resources, spectrum resources shared to support heterogeneous networks; different dynamic radio resource allocation method includes one kind of multi-dimensional features, support for heterogeneous network mode of control mechanisms.

[0006] 本发明为解决上述技术问题所采用的技术方案为:采用一种无线资源控制终端动态分配区域内可用无线资源以提供给不同的无线通信系统使用,从而支持异构网络拓扑架构下的频谱资源共享,无线资源控制终端将其掌握的无线资源在多个维度动态划分,通过控制不同无线通信系统对无线资源的使用方法,从而获得最大的无线资源利用率;其特征包括以下步骤: [0006] Technical Solution The present invention to solve the above technical problem is: a radio resource control using the dynamic allocation of the available radio resources to the terminal area provided to different wireless communication systems use to support the heterogeneous network topologies shared spectrum resources, the radio resource control terminal to control the dynamic resource partitioning in wireless multiple dimensions, by using a method of controlling radio resources different wireless communication systems, for maximum utilization of radio resources; characterized by comprising the steps of:

[0007] A、无线资源控制终端周期性的获得无线通信系统的无线资源需求及所辖区域无线资源,并将掌握的无线资源构造成无线资源容器,根据无线资源需求的各个特征将无线资源需求进行分组、排除、排队,形成无线资源需求预选队列; [0007] A, the radio resource control terminal periodically obtaining a wireless communication system and a radio resource needs administrative area radio resource, and radio resource control RRC configured container, wherein the radio resource in accordance with various requirements of radio resource requirements group, exclude, queue, a queue is formed preselected radio resource requirements;

[0008] B、预选队列中的无线资源需求通过一种优化布局方法逐一布局到多维无线资源容器中,无线资源容器合理划分成无线资源块,无线资源控制终端为所辖区域无线通信系统分配无线资源块,即资源子容器,而无线通信系统使用该资源块的过程构成了业务封装在资源子容器过程,无线资源需求在资源容器中的优化布局过程即是资源子容器在资源容器中的优化布局过程; [0008] B, radio resource requirements preselected queue one by one by means of a method of optimizing the layout to a layout container multidimensional radio resource, the radio resource into a container reasonable radio resource block, radio resource control jurisdiction terminal is a wireless area of ​​the wireless communication system allocates resource blocks, i.e., resource sub-tank, and a wireless communication system using the resource block processes constitute a service encapsulated in the sub-tank process resources, a radio resource needs to optimize the layout process in the resource container that is to optimize resources subcontainers resource container layout process;

[0009] C、经过无线资源需求在无线资源容器中的布局,将优化分配的无线资源块分发给各个通信系统;根据无线资源需求公平性要求,对上次未布局到无线资源容器中的无线资源需求优先级进行变更,使得其在下一轮的布局中得到服务。 [0009] C, through a radio resource radio resource demand distribution vessel, the optimal allocation of resource blocks distributed to the radio communication system; fairness requirements of the wireless resource according to the demand, not for the last container in the layout radio resource radio resource requirements priorities change, so that its layout to get the next round of service.

[0010] 所述步骤A中,无线资源控制终端之间构成异构网络的无线资源管理与控制系统,无线资源控制终端掌握所辖区域的无线资源,并在所辖区域采用无线广播通知该区域可以使用的无线资源及其使用规则,同时阻塞违规使用。 [0010] In the step A, the radio resource management and control system composed of a heterogeneous network between the terminal RRC, radio resource control RRC jurisdiction terminal control area, and wireless broadcast area under the jurisdiction of the notification area wireless resources and their usage rules that can be used, while blocking illegal use.

[0011] 所述步骤A中,无线资源控制终端对无线资源需求一方面可以通过无线通信系统发送资源请求信息获得,但由于无线资源需求的突发性和无线资源的时变特性,无线资源控制终端可以依靠观测无线资源的使用状态来预测需求及自己掌握的资源,克服了无线资源的时变性影响。 [0011] In the step A, the radio resource control demand for wireless terminal may send a resource request the resource aspect of the information obtained by the wireless communication system, but the sudden and time-varying characteristics of radio resources of the radio resource requirements, RRC the terminal may rely on the use of radio resources of a state observer to predict demand and control their own resources, to overcome the effects of time-varying radio resources. 异构网络无线资源按照其时间域,频率域,空间域和能量域特性划分,构成欧式空间上的无线资源容器;无线资源控制终端掌握的资源容器是由时间域、频率域、空间域、能量域中两种或多种维度序列构成的多维无线资源容器。 Heterogeneous network radio resources in their time domain, frequency domain, spatial domain, and characteristic energy regions divided, a radio resource configuration of the container Euclidean space; RRC container terminal by the available resources in time domain, frequency domain, spatial domain, the energy two or more dimensions domain sequence consisting of multidimensional radio resource container.

[0012] 所述步骤A中,无线资源控制终端将获得的无线资源需求按照其各种特性,资源需求优先级、无线资源需求尺度、可靠性需求进行整合分组,排除尺度要求及可靠性要求不满足的无线资源需求,按照无线资源需求的需求优先级由高到低和无线资源需求尺度由大到小对其进行排队,形成无线资源需求预选队列。 [0012] In the step A, the radio resource control radio terminal and obtain resource requirements according to their various characteristics, resource requirements, priorities, radio resource requirements scale integration grouping reliability requirements, reliability and negative scale is not required meet the needs of a radio resource according to the priority from high to low demand and the radio resource requirements descending scale radio resource requirements for its queue, the queue is formed preselected radio resource requirements.

[0013] 所述步骤B中,无线资源控制终端根据其所辖区域内的无线通信系统的工作模式和资源需求特征,分配满足无线通信系统特定需求的无线资源域,支持并协调无线通信系统以集中控制式工作模式、协商式工作模式、竞争工作模式工作。 [0013] In the step B, the radio resource control mode of the wireless terminal communication system according to the operating area within which it needs and characteristics of resources allocated to meet the specific needs of a wireless communication system, radio resource domains, to support and coordinate the radio communication system centralized control mode, consultative mode, competitive mode of work.

[0014] 所述步骤B中,无线资源控制终端协调异构网络中的无线通信系统,避免以集中控制式工作模式、协商式工作模式、竞争工作模式所产生的多种工作模式之间对无线资源需求的冲突,其方法是:满足无线通信系统工作模式所支持的无线资源需求优先级,根据不同工作模式控制能力的差别,满足控制能力低的工作模式对无线资源的需求,也就是:先满足高优先级,后满足低优先级;先满足竞争工作模式,最后满足集中控制模式。 [0014] In the step B, the terminal RRC coordination wireless communication system in a heterogeneous network, to avoid radio between a plurality of operating modes to centralized control type operating mode, negotiated operating mode, the operating mode competition generated conflict resource requirements, the method is: to meet the wireless communication system operating modes supported by the radio resource demand priority control different capabilities depending on the mode, to meet the low ability to control operating modes demand for wireless resources, namely: first meet high-priority, low priority after the meet; to meet the competition mode, and finally meet the centralized control mode.

[0015] 所述步骤B中,无线资源容器将根据不同的无线资源需求被划分为适应不同工作模式无线通信系统的多维度的资源子容器,所有子容器在各个维度空间代数和小于控制终端所掌握的无线资源容器。 [0015] In the step B, the radio resource is divided into a vessel adapted to different operating modes multidimensional wireless communication system according to a resource sub-tank depending on the radio resource requirements, all descendants of each spatial dimension less than the algebraic sum of the control terminal master radio resource container. 子容器包括管理信息块和满足无线通信系统资源需求的业务信息块;无线资源控制终端为所辖区域无线通信系统分配资源子容器,而无线通信系统使用该子容器的过程构成了业务封装在资源子容器过程。 Management information block including the sub-tank and service information block satisfies a wireless communication system resource requirements; RRC resources assigned to the terminal sub-region of the container is under the jurisdiction of a wireless communication system, a wireless communication system using the sub-container package business processes constituting the resource sub-container process.

[0016] 所述步骤B中,无线资源控制终端将预选队列中无线资源需求按顺序逐一布局到资源容器中,发现有低优先级无线资源需求布局到资源容器中而高优先级无线资源需求不能布局到资源容器中,将优先级最低且尺度最小的无线资源需求将其剔除出预选队列,建立新的预选队列,从剔除的无线资源需求位置重新对预选队列进行布局。 [0016] In the step B, the terminal RRC radio resource requirements preselected queue sequentially one by one to the resource layout container, found low priority radio resources to the resource distribution needs vessel and the higher priority radio resource demand can not resource layout container, and the lowest priority scale minimum radio resource needs to be removed out of the preselected queue, establishing a new preselected queue, re-layout from the preselected reject queue position of a radio resource needs. [0017] 所述步骤B中,各个无线通信系统使用无线资源控制终端为其分配无线资源块的过程是业务封装在资源子容器过程;无线资源需求在无线资源容器中的优化组合是资源子容器在资源容器中的优化布局问题;这两者构成了两级资源利用度指标;第二级资源利用度决定于不同无线通信系统内部的资源使用方法,是无线通信系统实际使用资源量的代数和与所分配的资源子容器大小的比值;资源子容器在填装到无线资源容器中时,填装完毕的资源子容器不一定能完全占用无线资源容器的资源,资源子容器的容量代数和与容器大小的比值称为第一级资源利用度。 [0017] The step (B), each of the wireless communication system terminal using the radio resource control radio resource blocks allocated to the business process is encapsulated in a resource sub-process container; optimal combination RRC radio resource demand in the resource sub-container vessel layout optimization problem of resource container; constitutes both the two resource utilization index; resource utilization of the second stage depends on the internal resources of different wireless communication systems to use, the actual use of resources and a wireless communication system algebraic the ratio of size of the container and the sub-resources allocated; resource sub-tank when filling the container a radio resource, the resource is completed filling the container may not fully occupy the sub-resources of the wireless resource of the container, the container capacity algebraic sub-resources and a the ratio of size of the container is referred to as a first stage of use of resources.

[0018] 所述步骤B中,无线通信系统工作在集中式工作模式下时,无线资源控制终端为集中式资源控制模式下的无线通信系统分配满足无线资源需求的子容器,同时将该子容器信息通知所辖区域的无线通信系统,集中式工作模式下的无线通信系统,由其内部集中控制端点对所掌握的资源再次分配。 [0018] In the step B, the wireless communication system operates in the centralized mode, the terminal RRC in a wireless communication system, centralized resource allocation control mode radio resources to meet the needs of the sub-tank, while the sub-tank area under the jurisdiction of the notification information of a wireless communication system, a wireless communication system in a centralized mode, centralized control by the internal end of the re-distribution of the resources.

[0019] 所述步骤B中,当无线通信系统工作在协商式工作模式下时,无线资源控制终端为集中式资源控制模式下的无线通信系统分配满足无线资源需求的子容器,同时将该子容器信息通知所辖区域的无线通信系统,协商式工作模式下的无线通信系统具有对等的资源使用权利,通过控制信息相互进行请求、确认,进行资源协商,对所掌握的资源再次分配。 [0019] In the step B, when the wireless communication system is operating in the working mode negotiated, radio resource control terminal is a wireless communications system under centralized control resource allocation pattern of radio resources to meet the needs of the sub-tank, while the sub- Notify container area under the jurisdiction of a wireless communication system, a wireless communication system in the operating mode negotiated with the use of resources such as claimed, each request control information, acknowledgment, resource negotiation on the resource allocation control again.

[0020] 所述步骤B中,当无线通信系统工作在竞争式工作模式下时,无线资源控制终端为集中式资源控制模式下的无线通信系统分配满足无线资源需求的子容器,同时将该子容器信息通知所辖区域的无线通信系统,并可以在非竞争式资源控制的子容器中发送竞争模式的阻塞信息。 [0020] In the step B, when the wireless communication system is operating in the contention mode, radio resource control terminal is a wireless communications system under centralized control mode resource allocation of radio resources to meet the needs of the sub-tank, while the sub- Notify container area under the jurisdiction of the wireless communication system, and congestion information may be transmitted in the sub-tank competitive model non-contention resource control.

[0021] 所述步骤C中,无线资源控制终端获得的无线资源需求若没有布局到无线资源容器中且其有公平性要求,则相应提高本次未能获得服务的无线资源需求的需求优先级,从而提高无线资源需求下次布局到资源容器中时服务成功可能性;如果预选队列中所有需求已经布局或者无线资源容器不能承载任何无线资源需求,则将划分后的资源子容器分配给各无线通信系统。 [0021] In the step C, the radio resource control radio terminal obtains resource requirements if no radio resource layout container and its fair requirements, the corresponding increase in the current demand for services unable to obtain priority radio resource requirements , thereby increasing the demand for radio resources when the likelihood of success of the next distribution service resource container; queue if all demand has been preselected layout, or containers do not carry any radio resource radio resource requirements, resource sub-tank after the division will be assigned to each of the radio Communication Systems.

[0022] 所述步骤A中,在一个周期时间内,无线资源控制终端将重复执行权利要求1所述步骤A、B、C ;每隔一个周期,无线资源控制终端重新对自己掌握的资源和无线通信系统的无线资源需求进行获得。 [0022] In the step A, over a period of time, the terminal RRC claim 1 repeatedly performs Step A, B, C; every other cycle, the terminal RRC re available resources and their wireless radio communication system resource requirements were obtained.

[0023] 本发明结合上述A、B、C三点描述,在支持频谱资源共享的异构网络中,通过无线资源预测机制,在多维空间中划分无线资源,满足了异构网络中不同工作模式的无线通信系统对无线资源的需求。 [0023] The present invention combines the above-described A, B, C described three points, the shared spectrum resource to support the heterogeneous network, radio resource prediction mechanism, dividing radio resources in a multidimensional space, the heterogeneous network to meet the different operating modes demand for wireless communication systems for radio resources.

[0024] 本发明的有益效果为:提出了一种支持频谱资源共享的无线资源分配方法,通过对无线资源在多维度空间划分,采用适应多工作模式无线通信系统的资源分配机制、以及无线资源需求的预测机制,提高了无线资源利用效率、避免了异构网络之间的无线资源需求冲突。 [0024] Advantageous effects of the present invention are: radio resource allocation method is proposed for supporting a shared spectrum resources, the radio resource divided by a multi-dimensional space, using the resource allocation mechanism to adapt to multi-mode wireless communication systems work, and a radio resource prediction mechanism needs to improve the radio resource utilization efficiency, avoiding the conflicting demands of radio resources between heterogeneous networks.

[0034] 下面根据附图和实施例对本发明作进一步详细说明: [0034] The following figures and examples will be further detailed description of the invention:

[0035] 实施例以无线资源为具有时域、频域特性的二维资源为例阐述异构网络的多维无线资源分配方法。 [0035] Example wireless resource time-domain, multi-dimensional radio resource assignment method in a heterogeneous network of a two-dimensional frequency domain characteristics RESOURCE forth.

[0036] 图1描述了本发明提供的支持频谱资源共享的无线资源分配方法的使用环境。 [0036] Figure 1 depicts a spectrum resource to support the present invention provides a use environment shared radio resource allocation method. 其中异构网络无线资源控制终端掌握所辖区域的无线资源,并在所辖区域通过实时的无线广播通知该区域可以使用的无线资源及其使用规则,并且阻塞违规使用。 In which heterogeneous network terminal RRC radio resource control their areas of jurisdiction, and their areas of jurisdiction in real-time radio broadcasts to inform the radio resources in the region that can be used and usage rules, and by blocking illegal use. 无线资源控制终端之间构成异构网络的无线资源管理与控制系统,异构网络中的无线通信系统按照无线资源管理与控制系统的规划使用无线资源。 Radio resource management and control system including heterogeneous networks between RRC terminal, a wireless communication system in a heterogeneous network using a radio resource according to radio resource management planning and control system.

[0037] 图2是无线资源控制终端构造的二维无线资源容器。 [0037] FIG. 2 is a radio resource control terminal a radio resource configuration of the container two-dimensional. 二维无线资源容器具有时间、频率二维特性,横轴描述异构网络无线资源的频率域,频率特性以子载波为基本单位从(0,0)点开始沿横轴增加,构成无线资源容器的“宽度轴”,频率子载波总数目为无线资源控制终端所管理的频率资源宽度;纵轴描述异构网络无线资源的时间域,时间特性以时隙为单位自(0,0)点沿纵轴增加构成无线资源容器的“高度”,为无线资源控制终端所管理的一个时间周期内总时隙资源,该二维无线资源容器具有10个时隙数目和10个子载波数目。 A container having a two-dimensional radio resource time, frequency characteristics of a two-dimensional horizontal axis describes the frequency-domain radio resource in a heterogeneous network, the frequency characteristics of the subcarrier is increased from the basic unit (0,0) starts along the horizontal axis, a radio resource configuration of the container the "width axis", the total number of sub-carrier frequency of the radio resource control terminal managed frequency resource width; longitudinal described heterogeneous network radio resources in time domain, the time from the characteristic units of slots (0,0) in a radio resource configuration increases the vertical axis of the vessel, "height", the total period of time slot resources of a radio resource control terminal managed by the two-dimensional radio resource container 10 having a number of slots 10 and the number of sub-carriers. 图2中A示出无线资源容器内1个时隙单位与1个子载波单位构成的最小可调度的无线资源单位,即一个资源符号,一个时间周期内该无线资源容器具有100个资源符号。 Figure 2 A shows the minimum unit of scheduling radio resources in radio resource container with a unit of one slot unit composed of sub-carriers, i.e., a symbol resource, a time resource of the radio resource container 100 having the symbol period.

[0038] 图2中B示出控制终端将无线通信系统的无线资源需求装入到无线资源容器中形成的二维资源子容器,该无线资源需求的尺度为(3,4),即需求子载波数目为3,时隙数目为4,形成资源子容器占用12个无线资源符号集合。 [0038] FIG. 2 shows the control terminal B charged to the radio resource requirements of the wireless communication system to a two-dimensional radio resource sub-container resource container is formed, the scale of demand for radio resources (3, 4), i.e., the sub-demand the number of carriers is 3, the number of slots is 4, to form a resource sub-tank 12 occupies a radio resource symbol sets. 无线资源容器将根据不同的无线资源需求被划分为适应不同工作模式无线通信系统的资源子容器,资源子容器包括管理信息块C和满足无线通信系统资源需求的业务信息块D。 Radio resources will be divided into the container to accommodate different operating modes of the wireless communication system resources sub-container, depending on the resources of the sub-tank includes radio resource management information block C requirements and resource needs to meet the service information block of a wireless communication system D.

[0039] 二维无线资源容器划分中产生两种资源利用度,无线资源容器根据无线资源需求划分后形成的矩形资源子容器必须能够承装无线资源需求,在无线通信系统将业务封装到子容器过后,资源子容器中会有一些没有封装的资源符号被浪费,业务封装占用资源符号数与子容器资源符号数目的比值为第二级资源利用度。 [0039] The two-dimensional radio resource division produce two container resource utilization of radio resources means the container must be able to withstand the radio resource requirements according to the resource sub-rectangular container formed after division of radio resource requirements, in a wireless communication system to service the sub-container package after, the container will have some subset of resources unpackaged symbol resources are wasted, the number of symbols and the number of service package footprint symbol sub container resource utilization ratio of the resources of the second stage. 各个矩形的资源子容器在无线资源容器中进行布局,当不能够完全占用无线资源容器的资源符号,有一部分会被浪费,子容器占用总资源符号数目与无线资源容器资源符号数目的比值为第一级资源利用度。 Resource sub-containers each rectangular layout radio resource container, when not fully occupied radio resources container resource symbols, some will be wasted, the total number of symbols resources and the number of radio resources container resource symbols ratio of the sub-tank occupied for the first a degree of resource utilization. 本发明主要考虑第一级资源利用度的资源子容器布局方法。 The present invention is primarily considered a method of the first resource sub-tank layout stage resource utilization degree.

[0040] 本发明采用一种容器装箱算法来实现分配给无线资源需求的资源子容器在无线资源容器中的优化组合,提高第一级资源利用度。 [0040] The present invention employs a container packing algorithm to optimize the combination of radio resources allocated to the resource needs radio resources in a sub-container in the container, the first stage of the improved resource utilization. 容器填装算法中矩形子容器的尺度取决于无线通信系统发送的资源请求信息以及无线资源控制终端对无线通信系统资源需求的预测。 Filling the container and the predicted resource request information terminal RRC algorithm rectangular sub-scale container depending on the wireless communication system for transmitting a wireless communication demand for system resources.

[0041] 本实施例采用启发式二维装箱算法BLF算法(Bottom-Left-Fill)。 [0041] The present embodiment uses a heuristic algorithm for the two-dimensional packing algorithm BLF (Bottom-Left-Fill). BLF算法记录所有位置点,知道子容器都可以放在哪些地方。 BLF algorithm records all location points, know what needs to be sub-containers are placed. 放置一个子容器时,算法首先选择最低最左边(首先考虑最低点,如果高度相同则选择最左边的)的位置点进行放置,并检查该物体是否与其它物体有重叠,如果没有重叠就将物体放置在此并更新保存位置点列表,否则尝试下一个位置点,直到物体没有任何重叠发生地放在某一个位置点为止。 When placing a child container, the algorithm first selects the lowest leftmost (lowest first consideration, if the same height is selected leftmost) position of placement point, and checks whether the object overlaps with other objects, if the object will not overlap placed in this position and update the save point list, or try the next point position until the object is no overlap a position to put up some points. 由于无线资源需求子容器布局中要考虑无线资源需求特征等因素,所以在子容器布局中不能完全引用BLF算法。 As the wireless resource needs to be considered in the layout of the sub-container demand characteristics of wireless resources and other factors, it is not entirely BLF algorithm referenced in the sub-container layout. 实施例结合BLF算法的特点和多模式资源控制机制及无线通信系统资源需求预测机制,获得资源子容器布局的BLF改进算法。 Features and multi-mode resource demand prediction mechanism control mechanism and a wireless communication system resources Cases BLF algorithm embodiment, the layout of the sub-tank BLF obtained resource improved algorithm.

[0042] 本实施例中提出的二维无线资源动态分配方法的基本流程如下: The basic flow of [0042] a two-dimensional radio resource dynamic allocation method proposed in the present embodiment is as follows:

按尺度从大到小进行重新排队,形成进行布局的资源预选队列,如图3中35所示。 Press Requeues descending scale, forming a preselected resource queue layout, as shown in FIG 35.

[0050] 第2个步骤是将排队后得到的无线资源需求预选队列通过图3中36步骤BLF装箱算法将无线资源需求布局到无线资源容器;判断预选队列中和初始队列中是否有无线资源需求未被满足,判断无线资源容器是否剩余可以容纳剩余无线资源需求的资源符号等情况来执行图3中步骤37、38、39、40、41。 [0050] The second step is the line obtained after the radio resource requirements preselected queue BLF packing algorithm in step 3 in FIG. 36 needs radio resources to the radio resource distribution vessel; initial queue and the queue is determined whether there is a radio resource preselected demand is not satisfied, it is determined whether the remaining radio resource container can hold the radio resource remaining resource requirements symbols is performed in step 3 37,38,39,40,41 FIG.
