Description

频谱协调装置和方法、无线通信系统中的装置和方法 技术领域
本公开涉及无线通信技术领域，更具体地，涉及一种用于有效地协调具有不同资源分配粒度的多个系统对共享无线传输资源的使用的频谱协调装置和频谱协调方法以及该情况下的无线通信系统中的装置和方法。
背景技术
随着计算机和通信技术的迅猛发展，用户设备、业务需求以及使用场景的数量都将以指数级数的速度递增，进一步激化了无线业务需求与无线频谱资源之间的矛盾。传统的排它式频谱使用被证明是一种低效的资源使用方式。随着越来越多的新频谱资源从原有业务中被释放出来，成为可供多系统共享的动态访问资源，为共享系统的扩容提供了可能。各标准组织竞相从各技术角度出发制定相应共享准则，例如，3GPP组织的LTE(Long-Term Evolution,长期演进)-LAA(License-Assisted Access，授权辅助接入)工作组以及IEEE的802.19工作组，以期实现高效的共享。
尽管多系统的资源共享从增加可用频谱的角度为系统容量的增加提供了可能，但是多系统共存由于各个系统的RAT(Radio Access Technology，无线访问技术)的不同而导致频谱划分和使用方法存在差异，同时这些无线访问技术对于频谱的使用的优先级也存在差异。目前尚未有技术对于不同RAT共享频段的使用差异进行协调以提高共享频谱对不同RAT用户的准入容量以及保证使用优先级，这将导致共享频段的低效使用，甚至破坏不同优先级的RAT对该频段的使用权限。

具体实施方式
在下文中将结合附图对本公开的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或 处理步骤，而省略了与本公开关系不大的其它细节。
以下将参照图1至图17详细描述本公开的实施例。
应指出，多系统共存需要首先考虑各自的无线访问技术对于频谱的分配方式和使用方式的差异。下面将以WI-FI和LTE共存为例对此进行描述。然而，应理解，本公开的实施例并不限于这两种系统共存的情况，而是可以应用于采用不同无线访问技术的任意两个或更多个系统共存的场景。例如，在美国和欧洲，越来越多的频段被释放出来用于多系统共享，例如用于广播电视的频段以及用于雷达通信的频段，因此本公开的技术也可以适用于以例如广播电视系统或者雷达系统替代以下实施例描述的WI-FI系统而与LTE系统共存的场景或者其它多个资源分配粒度不对称的系统共存场景(例如作为细粒度系统的WI-FI系统与作为粗粒度系统的广播电视系统之间共存的场景)。
首先，将参照图1A描述根据本公开的实施例的不同无线访问技术的频谱分配和使用方式的示例。图1A是示出根据本公开的实施例的不同无线访问技术的频谱分配和使用方式的示例的说明图。
如图1A所示，对于WI-FI系统，IEEE 802.11b/g标准工作在2.4GHz频段，频率范围为2.400至2.4835GHz，共83.5M带宽，划分为14个子信道，每个子信道宽度为22MHz，相邻子信道的中心频点间隔5MHz。相邻的多个子信道存在频率重叠(如子信道1与子信道2、3、4、5有频率重叠)，整个频段内只有3个子信道(1、6、11)互不重叠，互不干扰。另一方面，IEEE 802.11ac标准工作在5GHz频段，该频段上每个子信道宽度为20MHz，且相邻子信道间没有重叠，如图1B所示。当把5GHz频段的相邻子信道的中心频点间隔设为与其子信道带宽相等时，5GHz频段的划分方法可以看作是2.4GHz频段的特例。需要说明的是，WI-FI系统中的信道划分方法在不同频段不同国家各有差异，这里以2.4GHz频段和5GHz频段作为示意，本方法对于其它划分方式同样适用，下面仅以2.4GHz频段的WI-FI系统作为粗粒度的通信系统为例进行说明。
此外，如图1A所示，LTE系统在空中接口资源分配基本单位是物理资源块(Physical Resource Block,PRB)。1个PRB在频域上包括12个连续子载波，在时域上包括7个连续的常规OFDM符号周期。若子载波间隔为15kHz，则1个物理资源块PRB对应的是带宽为180kHz、时长为0.5ms的无线资源。
从图1A可以看出，WI-FI系统的资源分配基本单位(即，资源分配粒度)是带宽为22MHz的子信道，LTE系统的资源分配基本单位是带宽为180kHz的时频资源块，即两个系统的资源分配基本单位是不同的，这也决定了WI-FI系统和LTE系统对无线资源占用的方式是不同的。具体地，例如，WI-FI系统以子信道为资源分配基本单位，并且在通信时需要占用整个未被使用的22MHz的子信道进行通信，而LTE系统以物理资源块为资源分配基本单位，并且在通信时只需要占用一个完整的180kHz的PRB进行通信。一般地，在多系统共存的场景下进行频谱协调时，具有较小的资源分配粒度的无线通信系统具有更好的资源分配灵活性。
接下来，将参照图2描述根据本公开的实施例的频谱协调装置的功能配置示例。图2是示出根据本公开的实施例的频谱协调装置的功能配置示例的框图。
如图2所示，根据本实施例的频谱协调装置200可包括获取单元202和分配单元204。该频谱协调装置(Spectrum Coordinator，下文中也简称为SC)200可用于协调多个系统对共享无线传输资源的使用。下面将分别详细描述各个单元的功能配置示例。
获取单元202可被配置成获取共享无线传输资源的使用状态。
分配单元204可被配置成根据所获取的使用状态，基于多个系统中的一个系统的待分配资源粒子对多个系统中的其它系统的可用资源粒子的影响为该通信设备分配共享无线传输资源，其中一个系统的资源分配粒度比其它系统的资源分配粒度细。优选地，分配单元204还可基于来自多个系统中的一个系统的通信设备的资源请求而为该通信设备分配共享无线传输资源。
优选地，作为示例，一个系统可以是LTE系统，其资源分配粒度基于时频资源块(例如，上述物理资源块PRB)，资源粒子例如为PRB，并且其它系统可以是WI-FI系统、广播电视系统、雷达系统和红外系统中的一个或多个，并且对于WI-FI系统，其资源分配粒度基于具有预定带宽的子信道(例如，上述2.4GHz频段的具有22MHz带宽的子信道)，资源粒子例如为子信道。应理解，尽管这里以LTE系统和WI-FI系统的共存为例来描述本公开的技术，但是本公开不限于此，显然本公开的技术可以应用其它两个或更多个系统共存的情况。
此外，对于WI-FI系统和LTE系统的共享频谱，下文中也可简称为 LAA频谱，并且LTE系统中的支持LAA技术的设备也可简称为LAA设备。另外，还应指出，在该示例中，对于LAA频谱，WI-FI系统对该频谱资源具有较高的使用优先级，因此在实际分配资源时应当优先保证WI-FI系统对LAA频谱的使用。然而，这仅是示例，并且本公开的技术也可以应用于对频谱资源的使用优先级不存在差别的多个系统共存的场景，此时仍可基于具有更精细的资源分配粒度的系统对具有较粗的资源分配粒度的系统的资源可用性的影响来分配共享频谱资源。
优选地，获取单元202可被配置成通过以下方式中的至少一种来获取使用状态：信息交互；频谱感知；以及广播查询。下面将分别具体描述获取单元202如何获取WI-FI设备和LAA设备对LAA频谱的使用状态。
具体地，获取单元202可被配置成通过以下方式来获取WI-FI设备对LAA频谱的使用状态：(1)一种方式是SC 200与WI-FI的频谱管理数据库进行信息交互(例如，两者通过主干网(backhaul)互联)，该频谱管理数据库包含不同地理位置的WI-FI设备的实时频谱使用状况，通过地理位置信息可以查询到对应的频谱使用状况；(2)另一种方式是SC200本身具有频谱感知功能，从而获取单元202能够通过频谱感知来检测LAA频段是否被WI-FI设备占用，进一步地，SC 200配备的频谱感知器可以分布在目标管理区域内，从而获取单元202能够通过这些频谱感知器来获取各个频谱感知器周围的LAA频谱被WI-FI设备占用的情况；以及(3)另一种方式是SC 200可以发送状态信息查询广播，WI-FI设备在收到查询信息后，可以反馈自己的LAA频谱使用状态，例如终端用户配备了多模芯片，从而可以支持不同无线技术的信息交互，此外，随着虚拟化技术(例如，虚拟功能网络(Virtual Functional Network，VFN))的发展，也可以使用共有的虚拟化平台实现不同无线访问技术之间的信息交互。
另外，获取单元202可被配置成通过以下方式来获取LAA设备对LAA频谱的使用状态：(1)一种方式为信息交互，即，LAA设备将使用频谱和释放频谱的信息告知SC 200，以便SC 200维护LAA设备对LAA频段的使用状态，可以利用LTE的Uu接口信令例如通过物理上行控制信道(PUCCH)和物理下行控制信道(PDCCH)进行信息交互；以及(2)同样，也可以通过如上述频谱感知方法获取LAA频谱被LAA设备占用的情况。
为了更精确地实现频谱资源分配，这里所获取的使用状态不仅可包括 LAA频谱的哪些频段被占用，还可包括占用这些频段的设备的类型(即，是WI-FI设备还是LAA设备)。此外，在LAA频谱被LAA设备占用的情况下，该使用状态还可包括占用LAA频谱的LAA设备的数量。LAA设备可以共享LAA频谱的相同资源块，这些共享情形包括：来自同一小区的蜂窝用户与D2D(device to device，设备到设备)用户之间的共享，来自不同小区的蜂窝用户与D2D用户各种组合之间的共享，或者来自不同运营商的蜂窝用户与D2D用户各种组合之间的共享，等等。
LTE中的通信设备(即，LAA设备)向SC 200发送的资源请求可根据其自身的QoS(服务质量)需求而进行限定，并且可包括业务量需求、地理位置信息和资源使用优先级中的至少一个。例如，LAA设备可在资源请求中包括业务量需求以向SC 200请求可用频谱的数量；LAA设备可在资源请求中包括其地理位置信息以获得更精准的可用频谱信息；此外，如果希望进一步在可用频谱中进行筛选，LAA设备还可在其资源请求中附加资源使用优先级信息(例如，频谱序列请求)，从而SC 200可根据优先级的高低而对可用频谱进行排序，并且将可用频谱序列通知给LAA设备。应指出，该资源请求也可以是感知频谱请求，在该情况下，SC 200可以为例如LAA设备分配感知频谱集合或感知频谱序列，以由LAA设备感知所分配的感知频谱集合或感知频谱序列中的各个PRB是否被占用。
LAA频谱的总量一定，LAA设备占用的频谱越多，则WI-FI设备的可用频谱就越少，因此，在为LAA设备分配可用频谱资源时，可通过限制LAA设备占用的LAA频谱的总量及分布来减小对未来WI-FI设备的影响，这是由于在该应用场景下必须优先保证WI-FI设备对LAA频谱的使用以及LTE系统中的资源分配的灵活性。此外，由于WI-FI设备在实际使用资源时需要占用整个完整的子信道，所以即使LAA设备占用的频谱数量相同，分布不同也会影响WI-FI设备的可用频谱数量。图3(a)至图3(c)是示出根据本公开的实施例的共享无线传输资源(即，LAA频谱)的不同资源分配状态的示例的说明图。如图3(a)至图3(c)所示，假设一个灰色方块代表一个PRB，对于同样的分配给LAA设备的三个PRB。在图3(a)中，三个PRB连续排列占用LAA频谱，占用了WI-FI设备的子信道1的频谱(虚线所示)，但子信道2和3的频谱没有被占用，因此可以被WI-FI设备使用；在图3(b)中，3个PRB占用了WI-FI设备的子信道1，2的频谱，因此仅子信道3可以被WI-FI设备使用；而在图3(c)中，3个PRB分别占用了WI-FI设备的子信道1，2，3的频谱，因此没有子信道 可以被WI-FI设备使用。
因此，基于上述，为LAA设备选择可用频谱的前提之一可以是为WI-FI设备预留可用资源。因此，优选地，分配单元204可进一步被配置成以使得其它系统的可用资源粒子与已占用资源粒子的数量之和不小于其它系统的预留资源粒子数量的方式，从待分配资源粒子中为通信设备分配资源。
应指出，如上所述，WI-FI系统对LAA频谱的高使用优先级，需要为WI-FI设备预留可用资源主要是由于两个系统在资源分配粒度上的不对称造成的资源分配不公平：WI-FI系统成功传输需要独占粒度较粗的子信道，当达到其传输的最大占用时长，可以空出该子信道以重新分配；LTE系统采用了较细粒度的资源块进行分配，尽管对每个资源块设定了最大时长使得该资源块有机会空出来以重新分配，但是可能存在一个子信道内对应的所有资源块在任何一个时刻总存在至少一个资源块被LAA设备占用的情形，即该子信道一直被LAA设备部分或全部占用，从而导致整个子信道无法完全空出来从而能够分配给WI-FI设备。本发明解决了这个问题。可以理解，对于同一个通信频谱，在被粗粒度和细粒度的系统使用时，细粒度的使用数量大于粗粒度的使用数量，诸如一个玻璃空瓶，粗粒度的为大枣，细粒度的为小米，同一个玻璃空瓶可以装载的小米数量要大于大枣的数量。粗粒度的系统的每个资源粒子对应的细粒度系统的资源粒子的数目越多，从而更可能受其影响，因此当两个系统资源分配粒度差异越大，本发明对提高频谱利用率和保证系统间的资源分配公平性的效果越好。具体地，假设为WI-FI设备预留的可用子信道数为Nres；在满足该预留的同时，可按照对WI-FI子信道的影响从小到大以及LAA设备的性能从高到低的顺序选择可用频段分配给LAA设备。此外，预留的可用子信道数Nres也可以是动态变化的。例如，在一天中的不同时段和不同位置，WI-FI设备的平均到达量有所变化，因此可以根据该变化为WI-FI设备预留可用资源以保证其接入率。
根据对WI-FI子信道的影响以及是否被LAA设备占用，可以将LAA频谱分成以下3类：
第一类：空闲频段，如果被LAA设备占用不会增加对WI-FI子信道的影响；
第二类：空闲频段，如果被LAA设备占用会增加对WI-FI子信道的影响；以及
第三类：已被LAA设备占用的频段，不会增加对WI-FI子信道的影响但需要支持LAA设备间的资源复用并且需要进行干扰控制。
尽管在本公开的实施例中主要讨论以上三种类型的LAA频谱，但是LAA频谱还可包括第四类，即，已被WI-FI设备占用但是未被全部使用且允许其它设备接入的频段，当为LAA设备分配这类频段时不会增加对WI-FI子信道的影响，但是需要考虑LAA设备是否被授权使用该资源，以及所授权的使用该资源的原则。
从以上所划分的LAA频谱的种类可以看出，第一类资源的优先级最高，其不会增加对WI-FI子信道的影响且不存在设备间干扰。从对WI-FI子信道的影响来看，第二类资源的优先级最低。此外，从使用效率来看，第三类资源的优先级最低。在实际选择这三类资源时，需要结合实际的需求以及来自LAA设备的资源请求综合进行考虑。
可以理解的是，为了便于说明，在本公开中描述了具有LTE系统和WI-FI系统的示例场景，并且WI-FI系统的资源分配粒度大于LTE系统的资源分配粒度。然而，同时也允许其他系统诸如广播电视系统、雷达系统和红外系统中包括在其中，在有两个系统并存时需要考虑两个系统之间的资源分配粒度的精细程度，当有三个系统或者更多个系统并存时，则需要对资源分配粒度进行排序，并且根据排序进行相应的选取和分配。
此外，可以理解的是，在实施当中，某一系统也可以具有对共享资源的优先使用权，即，在考虑其资源分配粒度的同时，根据其对共享资源的优先使用权而可以优先使用该共享资源。
如图1A所示，WI-FI子信道的起点和终点依次将LAA频谱划分成若干个频段，称为单元频段(5MHz)，同一个单元频段内的资源对WI-FI子信道的影响是相同的。因此，以上三类可进一步表示为：
第一类，空闲频段，且和某个已经被LAA设备占用的频段处于同一个单元频段；
第二类，空闲单元频段；以及
第三类，已被LAA用户占用的频段。
分配单元204可以将这三类资源以任意组合的方式分配给LAA设备，只要满足以下条件：
在第一类中，按照LAA设备的QoS需求，选择足够的可用频谱分配 给LAA设备；
在第二类中，由于此类资源会新增对WI-FI子信道的影响，所以需要保证选择之后剩余可用的WI-FI子信道数与已经被WI-FI占用的子信道数之和不小于Nres；以及
在第三类中，只要支持LAA设备间的资源复用，则可以选择此类资源给新的LAA设备，但需要有干扰控制。
优选地，分配单元204可进一步被配置成根据其它系统的资源使用习惯而为通信设备分配资源，以减少与其它系统的资源使用碰撞。作为优选示例，分配单元204优先为通信设备分配其它系统占用概率低的资源。
具体来说，如果为LAA设备分配可用频谱序列(即，该可用频谱序列是按照使用优先级而排列的)，则可以考虑WI-FI设备占用LAA频谱的状态和其资源使用习惯(如经常占用某几个子信道或者通常不使用某几个子信道)以减少碰撞概率。基于此对上述三种类型进行进一步约束，这样选择的频谱单元(即资源粒子，如PRB)按照顺序就形成了可用频谱序列：
首先可以按照上述三类资源依次选择资源，只有当一类资源不存在，或者选择完毕仍然不能满足LAA设备的需求时才进一步选择下一类；
在第二类中，可以按照单元频段影响WI-FI子信道的个数从少到多为其排序，并按照此顺序为LAA设备分配可用频谱；以及
在第三类中，按照其上已经存在的LAA设备的个数从少到多为频谱单元(如PRB)排序，并按照此顺序为LAA设备分配可用频谱。
此外，可以优先选择被WI-FI设备占用概率较低的频段，从而可以减少为WI-FI设备进行资源释放所需的开销。
此外，应指出，可以理解，与LTE系统的待分配资源粒子处于同一个子信道内(更具体地，例如同一个单元频段内)的已占用资源粒子对资源分配也存在影响。因此，优选地，分配单元204可进一步被配置成根据与待分配资源粒子对应于其它系统的同一资源粒子的、一个系统的已占用资源粒子的使用状况，从待分配资源粒子中为通信设备分配资源。
具体地，作为示例，假设WI-FI系统的子信道1包括LTE系统的待分配资源粒子PRB1和已占用资源粒子PRB2，并且WI-FI系统的子信道2包括LTE系统的待分配资源粒子PRB3和已占用资源粒子PRB4。由于 WI-FI设备在实际使用时需要占用整个子信道，因此在根据所分配的资源对WI-FI可用子信道的影响从待分配资源粒子PRB1和PRB3中选择要分配给LAA设备的资源时，还需要考虑已占用资源粒子PRB2和PRB4的使用状况。例如，假设PRB2已被占用了较长时间并且其使用期限快要到期，而PRB4被占用的时间较短并且其剩余使用时间还较长，则在分配时可以优先选择PRB3分配给LAA设备。反之，如果选择PRB1，本来子信道1的资源很快将被释放可供WI-FI设备使用，而此时子信道1将被继续占用而无法为WI-FI设备使用，从而相比于选择PRB3的情况增加了未来对WI-FI子信道的影响。
进一步优选地，分配单元204可被配置成根据一个系统的已占用资源粒子的使用期限而确定分配给通信设备的资源的使用期限。
具体来说，例如，为了避免某部分LAA频段被LAA设备一直占用从而影响WI-FI设备使用LAA频段的优先性以及兼顾资源使用的公平性，需要为占用LAA频段的LAA设备定义使用期限。此外，使用期限的定义还提供了为WI-FI释放资源的有效控制方法，LAA设备可以在使用期限到期时自动释放占用的资源，从而减少了信令开销。该使用期限可以是某个预设的固定值Tmax，也可以根据LAA设备的占用情况动态选择。
例如，某个单元频段当前有部分PRB已被一些LAA设备占用，所有这些PRB的最大剩余使用时间为
Figure PCTCN2016075455-appb-000001
而该单元频段释放出去可以减少被影响的WI-FI子信道数，则该单位频段内的其余可用PRB当前分配给其它LAA设备的最大可用时间(即，使用期限)可以设为
Figure PCTCN2016075455-appb-000002
从而LAA设备将在设定的使用期限内占用LAA频谱。
接下来，将参照图4描述根据本公开的另一实施例的频谱协调装置的功能配置示例。图4是示出根据本公开的另一实施例的频谱协调装置的功能配置示例的框图。
如图4所示，根据该实施例的频谱协调装置400可包括获取单元402、资源划分单元404和分配单元406。其中，获取单元402和分配单元406的功能配置示例与以上参照图2描述的获取单元202和分配单元204的功 能配置示例基本上相同，在此不再重复描述。下面将仅详细描述资源划分单元404的功能配置示例。
资源划分单元404可被配置成基于一个系统对其它系统的资源可用性的影响对共享无线传输资源进行划分，从而分配单元406可进一步被配置成根据共享无线传输资源的划分而为通信设备分配资源。
频谱划分的目标是尽可能减少一个系统对其它系统的频谱可用性的影响。所谓的可用性可以描述为可分配的资源粒子的个数。具体地说，频谱划分策略需要保证一个系统的任意一个资源粒子被该系统的设备占用时，其它系统的可用资源粒子数量达到最大。
优选地，作为示例，资源划分单元404可以以使得一个系统的资源粒子与其它系统的资源粒子对齐的方式来划分共享无线传输资源，以减少一个系统对其他系统的资源可用性的影响。
如图1A所示，在WI-FI系统和LTE系统共存的场景中，对齐的结果为将WI-FI相邻信道的中间频点间隔的5MHz划分为LTE的连续25个PRB。这样，在进行后续的资源分配时，可以尽可能地减少LTE系统对WI-FI系统的资源可用性的影响。
应指出，上述频谱协调装置可在一个系统的基站中实现。具体地，频谱协调装置可在LTE系统中的eNB(演进型基站)中实现。在上述的WI-FI系统与广播电视系统共存的场景中，频谱协调装置可以例如实现为ETSI RRS标准中为WI-FI系统提供可用电视频段资源的地理位置数据库(Geolocation Data base)。接下来将参照图5描述该情况下的频谱协调装置的功能配置示例。
图5是示出根据本公开的另一实施例的频谱协调装置的功能配置示例的框图。
如图5所示，根据该实施例的频谱协调装置500可包括获取单元502、接收单元504、分配单元506和通知单元508。其中，获取单元502和分配单元506的功能配置示例与以上参照图2描述的获取单元202和分配单元204的功能配置示例基本上相同，在此不再重复其描述。接下来将仅详细描述接收单元504和通知单元508的功能配置示例。
接收单元504可被配置成接收来自一个系统的通信设备的资源请求。优选地，接收单元504还可接收关于一个系统的通信设备在所分配的资源中选择使用的资源的信息，以供频谱协调装置500更新和维护例如LAA 设备对LAA频谱的使用状态。
通知单元508可被配置成将所分配的资源(例如，可用资源集合或可用资源序列，或者感知频谱集合或感知频谱序列)通知给通信设备。此外，优选地，通知单元508还可将以上确定的使用期限通知给通知设备，从而通信设备可在该使用期限内使用从所分配的资源中选择的频谱资源进行通信。
图6是示出根据本公开的实施例的无线通信系统中的装置的功能配置示例的框图。
如图6所示，根据本实施例的装置600可包括请求单元602、接收单元604和选择单元606。接下来将详细描述各个单元的功能配置示例。
请求单元602可被配置成向上述频谱协调装置发送资源请求。如上所述，该资源请求可包括业务量需求、地理位置信息和资源使用优先级中的至少一个。该频谱协调装置用于协调包括该无线通信系统的多个系统对共享无线传输资源的使用。
接收单元604可被配置成接收频谱协调装置响应于资源请求而分配的资源。所分配的资源是频谱协调装置基于无线通信系统的待分配资源粒子对多个系统中的其它系统的可用资源粒子的影响而分配的，并且该无线通信系统的资源分配粒度比其它系统的资源分配粒度细。优选地，该无线通信系统可以是LTE系统，其资源分配粒度基于时频资源块(例如，上述物理资源块PRB)，并且其它系统可以是WI-FI系统、广播电视系统、雷达系统和红外系统中的一个或多个，并且对于WI-FI系统，其资源分配粒度基于具有预定带宽的子信道。
优选地，接收单元604还接收来自上述频谱协调装置的所分配的资源的使用期限。
选择单元606可被配置成根据服务质量需求而从所分配的资源中选择要使用的资源。具体地，例如，选择单元606可被配置成根据QoS需求而从所分配的频谱资源集合中随机地选择要使用的资源，或者可从所分配的频谱序列中顺次选择要使用的资源。
应理解，装置600可位于LTE系统中的用户设备中或者也可位于小小区的基站或者其它基础设施中，本公开对此不作限制。
图7是示出根据本公开的另一实施例的无线通信系统中的装置的功能配置示例的框图。
如图7所示，根据该实施例的装置700可包括请求单元702、接收单元704、选择单元706和通知单元708。其中，请求单元702、接收单元704和选择单元706的功能配置示例与以上参照图6描述的请求单元602、接收单元604和选择单元606的功能配置示例基本上相同，在此不再重复描述。以下将仅详细描述通知单元708的功能配置示例。
通知单元708可被配置成将关于选择单元706选择的要使用的资源的信息通知给频谱协调装置，以供频谱协调装置更新和维护例如LAA设备对LAA频谱的使用状态。
应指出，上述资源请求也可以是频谱感知请求，从而频谱协调装置根据所接收的频谱感知请求而分配感知频谱集合或感知频谱序列。以下将参照图8描述该情况下的无线通信系统中的装置的功能配置示例。
图8是示出根据本公开的实施例的无线通信系统中的装置的功能配置示例的框图。
如图8所示，根据本实施例的装置800可包括请求单元802、接收单元804、感知单元806和选择单元808。其中，请求单元802、接收单元804和选择单元808的功能配置示例与以上参照图6描述的请求单元602、接收单元604和选择单元606的功能配置示例基本上相同，在此不再重复其描述。下面将仅详细描述感知单元806的功能配置示例。
感知单元806可被配置成对所分配的资源进行感知。具体地，对于感知频谱集合，感知单元806可按照随机顺序进行感知，而对于感知频谱序列，则感知单元806可按照该序列的顺序依次进行感知并根据自己的实际QoS需求确定是否可占用该资源：对于上述第一类和第二类资源，如果通过频谱感知确认其上没有其它用户，即可确定可供LAA设备占用；对于第三类资源，可以通过频谱感知确认该类资源上已有的LAA设备对发出请求的LAA设备的干扰是否在可忍受的范围内，以确定是否占用该资源。
选择单元808可进一步被配置成根据感知结果并结合QoS需求而从所分配的资源中选择要使用的资源。
应理解，尽管以上描述了根据本公开的实施例的频谱协调装置和无线通信系统中的装置的功能配置示例，但是应理解，这仅是示例而非限制，并且本领域技术人员可根据本公开的原理对以上实施例进行修改，例如可对各个实施例中的功能模块进行添加、删除和/或组合等，并且这样的修改均落入本公开的范围内。
与上述描述的装置实施例对应的，将参照图9至图11描述根据本公开的实施例的频谱协调装置与无线通信系统中的装置之间的信令交互流程的示例。应指出，在以下描述的实施例中，以SC与LAA设备之间的交互为例进行描述，但是本公开不限于此，并且LAA设备也可以由除LTE系统之外的其它系统中的通信设备来替代。
图9是示出据本公开的实施例的频谱协调装置与无线通信系统中的装置之间的信令交互流程的第一示例的流程图。
在图9的示例中，SC可以为驻留在eNB内的一个功能模块，并且SC与LAA设备之间的信令交互例如可以使用LTE Uu接口。
如图9所示，首先，在步骤(1)中，SC如上获取LAA频谱的使用状态。接下来，在步骤(2)中，LAA设备向SC发送可用资源请求，该请求可使用PUCCH来传输。在步骤(3)中，SC可根据以上描述的方式为LAA设备分配可用频谱集合或可用频谱序列，并且在步骤(4)中将可用资源响应而发送给LAA设备，以通知LAA设备所分配的可用频谱集合或可用频谱序列以及各个PRB的使用期限，该响应可以使用PDCCH来传输。接下来，在步骤(5)中，LAA设备可根据实际QoS需求而在可用频谱集合或序列中选择要使用的频谱资源，并且在步骤(6)中将所选择使用的频谱资源的信息报告给SC，以供SC更新和维护LAA设备对LAA频谱的使用状态，该报告可使用PUCCH来传输。最后，在步骤(7)中，LAA设备可使用所选择的频谱资源在所规定的使用期限内进行通信。
接下来，将参照图10描述根据本公开的实施例的频谱协调装置与无线通信系统中的装置之间的信令交互流程的第二示例。图10是示出根据本公开的实施例的频谱协调装置与无线通信系统中的装置之间的信令交互流程的第二示例的流程图。
在图10的示例中，SC可以为驻留在eNB内的一个功能模块，并且SC与LAA设备之间的信令交互例如可以使用LTE Uu接口。
图10所示的信令交互流程与图9所示的信令交互流程基本上相同，不同之处仅在于，在步骤(2)中，LAA设备向SC发送感知频谱请求，从而在步骤(3)中SC为LAA设备分配感知频谱集合或感知频谱序列，并且在步骤(4)中将感知频谱响应发送给LAA设备，从而LAA设备在步骤(5)中结合QoS需求对该感知频谱集合或感知频谱序列进行感知以选择要使用的频谱资源。其余步骤中的处理与图9中的相应步骤中的处理 基本上相同，在此不再重复。
接下来，将参照图11描述根据本公开的实施例的频谱协调装置与无线通信系统中的装置之间的信令交互流程的第三示例。图11是示出根据本公开的实施例的频谱协调装置与无线通信系统中的装置之间的信令交互流程的第三示例的流程图。
在图11的示例中，SC处在核心网(例如，核心分组网演进(Evolved Packet Core，EPC))或者更高层的云端以控制多个eNB下的LAA设备，SC与eNB之间通过S1接口交互信息，并且eNB与LAA设备之间通过Uu接口交互信息。
如图11所示，首先，在步骤(1)中，SC获取LAA频谱使用状态。接下来，在步骤(2)中，LAA设备向eNB发送频谱感知请求，可以使用PUCCH进行传输。在步骤(3)中，eNB将多个LAA设备的频谱感知请求进行整合，即，每隔预定时间才将LAA设备的频谱感知请求发送给SC，因此可以认为这种频谱分配方式是半静态的。接下来，在步骤(4)中，eNB通过S1接口将整合的频谱感知请求发送给SC。在步骤(5)中，SC根据该请求以上述方式分配感知频谱集合或感知频谱序列，并且在步骤(6)中通过S1接口向eNB发送感知频谱响应，以向eNB通知所分配的感知频谱集合或感知频谱序列以及各个PRB的使用期限。在步骤(7)中，eNB进一步将感知频谱集合或感知频谱序列分配给各个LAA设备，并且在步骤(8)中通过感知频谱响应将分配结果发送给各个LAA设备，该感知频谱响应可使用PDCCH来传输。接下来，在步骤(9)中，LAA设备对感知频谱集合按照随机顺序进行感知，或者按照感知频谱序列顺序进行感知，并根据自己的实际QoS需求选择使用的频谱，然后在步骤(10)中向eNB报告其选择使用的频谱信息，可使用PUCCH来传输。在步骤(11)中，LAA设备占用所选择的频谱资源在使用期限内进行通信。eNB在步骤(12)中将各个LAA设备报告的频谱信息进行整合，并且在步骤(13)中将整合的信息通过S1接口通知给SC，以由SC更新和维护LAA设备对LAA频谱的使用状态。
应理解，上述步骤(3)和(12)中的eNB的整合操作是可选的，eNB也可无需对这些信息进行整合，而是在接收到来自LAA设备的信息之后直接报告给SC。
此外，进一步地，考虑到S1接口信息交互时间延迟较长，eNB向SC申请感知频谱的频率可以降低，即，根据其系统容量和用户业务量向SC 申请一段频谱并占用较长的时间，然后在该时间内仅为其LAA设备分配该频段中的频谱进行感知和使用；下一个周期再重新申请新的频段和使用时限。
此外，应指出，尽管以上参照图11描述了SC为LAA设备分配感知频谱集合或序列的情况，但是参照图11描述的信令交互流程也可适用于SC为LAA设备直接分配可用频谱集合或序列的情况，在此不再重复进行描述。
应理解，尽管以上参照图9至图11描述了根据本公开的实施例的频谱协调装置与LAA设备之间的信令交互流程的示例，但是本公开不限于此，本领域技术人员也可根据本公开的原理对上述流程进行修改。
与根据本公开的实施例的装置相对应地，本公开还提供了一种频谱协调方法。以下将参照图12描述根据本公开的实施例的频谱协调方法的过程示例。图12是示出根据本公开的实施例的频谱协调方法的过程示例的流程图。
如图12所示，根据本实施例的频谱协调方法1200可包括获取步骤S1202和分配步骤S1204。
在获取步骤S1202中，可获取共享无线传输资源的使用状态。
接下来，在分配步骤S1204中，可根据使用状态，基于一个系统的待分配资源粒子对多个系统中的其它系统的可用资源粒子的影响为通信设备分配共享无线传输资源，其中，一个系统的资源分配粒度比其它系统的资源分配粒度细。优选地，一个系统可以是LTE系统，并且其它系统可以是WI-FI系统、广播电视系统、雷达系统和红外系统中的一个或多个。具体的资源分配过程可参见以上装置实施例中相应位置的描述，在此不再重复。
图13是示出根据本公开的实施例的无线通信系统中的方法的过程示例的流程图。
如图13所示，根据本实施例的方法1300可包括请求步骤S1302、接收步骤S1304和选择步骤S1306。
首先，在请求步骤S1302中，可向上述频谱协调装置发送资源请求。频谱协调装置用于协调包括无线通信系统的多个系统对共享无线传输资源的使用。
接下来，在接收步骤S1304中，可接收频谱协调装置响应于资源请求而分配的资源。所分配的资源是频谱协调装置基于无线通信系统的待分配资源粒子对多个系统中的其它系统的可用资源粒子的影响而分配的，该无线通信系统的资源分配粒度比其它系统的资源分配粒度细。
然后，在选择步骤S1306中，可根据服务质量需求而从所分配的资源中选择要使用的资源。
更详细的处理过程可参见以上装置实施例中相应位置的描述，在此不再重复描述。
应指出，尽管以上描述了根据本公开的实施例的频谱协调方法和无线通信系统中的方法的过程示例，但是这仅是示例而非限制，并且本领域技术人员可根据本公开的原理对以上实施例进行修改，例如可对各个实施例中的步骤进行添加、删除或者组合等，并且这样的修改均落入本公开的范围内。
此外，还应指出，这里的方法实施例是与上述装置实施例相对应的，因此在方法实施例中未详细描述的内容可参见装置实施例中相应位置的描述，在此不再重复描述。
此外，根据本公开的实施例，还提供了一种电子设备，该电子设备可包括一个或多个处理器，处理器可被配置成执行上述根据本公开的实施例的频谱协调方法和无线通信系统中的方法。
应理解，根据本公开的实施例的存储介质和程序产品中的机器可执行的指令还可以被配置成执行与上述装置实施例相对应的方法，因此在此未详细描述的内容可参考先前相应位置的描述，在此不再重复进行描述。
相应地，用于承载上述包括机器可执行的指令的程序产品的存储介质也包括在本发明的公开中。该存储介质包括但不限于软盘、光盘、磁光盘、存储卡、存储棒等等。
另外，还应该指出的是，上述系列处理和装置也可以通过软件和/或固件实现。在通过软件和/或固件实现的情况下，从存储介质或网络向具有专用硬件结构的计算机，例如图14所示的通用个人计算机1400安装构成该软件的程序，该计算机在安装有各种程序时，能够执行各种功能等等。
在图14中，中央处理单元(CPU)1401根据只读存储器(ROM)1402中存储的程序或从存储部分1408加载到随机存取存储器(RAM)1403的程序执行各种处理。在RAM 1403中，也根据需要存储当CPU 1401 执行各种处理等时所需的数据。

根据需要，驱动器1410也连接到输入/输出接口1405。可拆卸介质1411比如磁盘、光盘、磁光盘、半导体存储器等等根据需要被安装在驱动器1410上，使得从中读出的计算机程序根据需要被安装到存储部分1408中。
在通过软件实现上述系列处理的情况下，从网络比如因特网或存储介质比如可拆卸介质1411安装构成软件的程序。

以下将参照图15至图17描述根据本公开的应用示例。
[关于eNB的应用示例]
(第一应用示例)

控制器1521可以为例如CPU或DSP，并且操作基站设备1520的较高层的各种功能。例如，控制器1521根据由无线通信接口1525处理的信号中的数据来生成数据分组，并经由网络接口1523来传递所生成的分组。控制器1521可以对来自多个基带处理器的数据进行捆绑以生成捆绑分组，并传递所生成的捆绑分组。控制器1521可以具有执行如下控制的逻辑功能：该控制诸如为无线资源控制、无线承载控制、移动性管理、接纳控制和调度。该控制可以结合附近的eNB或核心网节点来执行。存储器1522包括RAM和ROM，并且存储由控制器1521执行的程序和各种类型的控制数据(诸如终端列表、传输功率数据以及调度数据)。

(第二应用示例)
图16是示出可以应用本公开内容的技术的eNB的示意性配置的第二示例的框图。eNB 1630包括一个或多个天线1640、基站设备1650和RRH1660。RRH 1660和每个天线1640可以经由RF线缆而彼此连接。基站设备1650和RRH 1660可以经由诸如光纤线缆的高速线路而彼此连接。
天线1640中的每一个均包括单个或多个天线元件(诸如包括在MIMO天线中的多个天线元件)并且用于RRH 1660发送和接收无线信号。如图16所示，eNB 1630可以包括多个天线1640。例如，多个天线1640可以与eNB1630使用的多个频带兼容。虽然图16示出其中eNB 1630包括多个天线1640的示例，但是eNB 1630也可以包括单个天线1640。
基站设备1650包括控制器1651、存储器1652、网络接口1653、无线通信接口1655以及连接接口1657。控制器1651、存储器1652和网络接口1653与参照图15描述的控制器1521、存储器1522和网络接口1523相同。
无线通信接口1655支持任何蜂窝通信方案(诸如LTE和LTE-先进)，并且经由RRH 1660和天线1640来提供到位于与RRH 1660对应的扇区中的终端的无线通信。无线通信接口1655通常可以包括例如BB处理器1656。除了BB处理器1656经由连接接口1657连接到RRH 1660的RF电路1664之外，BB处理器1656与参照图15描述的BB处理器1526相同。如图16所示，无线通信接口1655可以包括多个BB处理器1656。例如，多个BB处理器1656可以与eNB 1630使用的多个频带兼容。虽然图16示出其中无线通信接口1655包括多个BB处理器1656的示例，但是无线通信接口1655也可以包括单个BB处理器1656。
连接接口1657为用于将基站设备1650(无线通信接口1655)连接至RRH 1660的接口。连接接口1657还可以为用于将基站设备1650(无线通信接口1655)连接至RRH 1660的上述高速线路中的通信的通信模块。
