<第一实施例>
图1示出了根据本申请的一个实施例的用于无线通信***中的装置100的结构框图,如图1所示,该装置100包括获取单元101以及确定单元102,所述获取单元101被配置为获取无线通信***所服务的区域中的特定用户设备的与分布有关的用户特征,所述确定单元102被配置为根据获取单元101所获取的用户特征来确定特定用户设备要使用的无线传输资源池中的资源的划分。
其中,本文所述的无线通信***例如包括网络管理设备以及用户设备,网络管理设备与用户设备配合操作以实现网络管理设备与用户设备之间的无线通信。示例性地而非限制性地,无线通信***可以包括蜂窝移动通信***比如LTE***、认知无线电通信***等。无线通信***为其覆盖范围内的用户设备提供无线通信服务,应该理解,在同一区域内,可能存在多个无线通信***,每一个无线通信***为该区域内的自己服务的用户设备提供无线通信服务。这些无线通信***可以属于不同的类型或者使用不同的通信协议,并且覆盖范围也可以不完全重合。
网络管理设备可以是基站或与用户设备互相配合使用的任何无线通信管理设备,例如,网络管理设备还可以是C-RAN(Cloud-RAN/Centralized-RAN)结构下(可能不存在小区概念)的基 带云设备,比如C-RAN架构下的彼此高速连通的BBU池中的任一BBU,或者认知无线电通信***中的协调器,等等。
用户设备可以是各种移动终端,比如具有蜂窝通信能力的移动终端、智能车辆、智能穿戴设备等,也可以是和宏基站进行无线通信的基础设施比如小小区基站。用户设备可包括一个或多个,当用户设备包括多个时,各个用户设备的类型可以不同。用户设备的类型可以根据业务类型、通信质量要求等来划分。特定类型的用户设备(以下也称为特定用户设备)的资源分配方式可以被设置为与其他类型的用户设备的资源分配方式不同以及/或者使用特定的无线传输资源,用户设备例如可以通过连接请求中的特定标识来指示其类型。
例如,本文中的特定用户设备可以为车联网(V2V)用户设备或者在频谱访问***(Spectrum Access System,SAS)中具有优先访问许可证的无线通信***的用户设备。为了便于理解,在后文中将结合这两种具体示例来详细描述本技术。但是,应该理解,本技术的应用范围并不受这些详细描述的限制。
上述网络管理设备可包括装置100,其中,获取单元101获取特定用户设备的与分布有关的用户特征。这样的用户特征反映了在无线通信***所服务的区域中的特定用户设备的分布状况。
在一个示例中,特定用户设备的用户特征可以用区域中特定用户设备的密度信息来表示。所述密度信息可通过统计单位面积内的特定用户设备的数量来确定。在另一示例中,所述分布特征可以为所述区域中单位时间内发送信息的特定用户设备的密度。所述信息可以为属于安全业务的信息。类似地,其中,所述区域中单位时间内发送信息的特定用户设备的密度为所述区域中单位时间内发送信息的特定用户的数量与该区域面积的比值。
此外,该用户特征还可以用其他参数比如特定用户设备的具体空间分布等来表示。在后文的具体描述中,将以密度信息为例,但是应该理解,这并不是限制性的。
在一个示例中,所述无线通信***所服务的区域可包括多个子区域,所述获取单元101可分别获取每一个所述子区域中的特定用户设备的与 分布有关的用户特征,从而后续所述确定单元102可根据不同的子区域中特定用户设备的与分布有关的用户特征来设定不同的无线传输资源的划分。通过将区域分成多个子区域,可针对不同子区域的特定用户设备使用的无线传输资源进行更精确的划分,从而能更好地降低选择无线传输资源的时延以及信息交互的时延。
在一个区域内仅存在一个所述无线通信***的情况下,获取单元101仅需获取该区域内所述无线通信***中的特定用户设备的用户特征即可。
在一个区域中存在两个或更多个无线通信***比如存在两个或更多个运营商运营的无线通信***的情况下,获取单元101还需要考虑其他无线通信***所服务的特定用户设备的与分布有关的用户特征的影响。为了便于描述,将装置100所在的无线通信***称为第一无线通信***,将其他无线通信***称为第二无线通信***。应该理解,“第一”和“第二”仅是为了进行区分,并不代表任何的限制。
在这种情况下,特定用户设备包括第一无线通信***服务的第一特定用户设备和第二无线通信***所服务的第二特定用户设备,第二无线通信***所服务的区域与第一无线通信***所服务的区域至少部分重叠,针对该重叠区域,获取单元101被配置为获取第一特定用户设备的与分布有关的第一用户特征以及第二特定用户设备的与分布有关的第二用户特征,并结合第一用户特征和第二用户特征以获得重叠区域中的特定用户设备的与分布有关的用户特征。其中,重叠区域例如可对应于某个子区域或子区域的一部分。
具体地,获取单元101可以被配置为从第二无线通信***获取第二用户特征以及向第二无线通信***提供第一用户特征。即,不同的无线通信***之间通过交互特定用户设备的与分布有关的用户特征,从而使得每一个无线通信***能够获得重叠区域中特定用户设备的实际的分布状况。
在用户特征用区域中特定用户设备的密度信息表示的示例中,获取单元101可以将关于重叠区域中第一特定用户设备的密度的第一密度信息和来自第二无线通信***的关于重叠区域中第二特定用户设备的密度的第二密度信息相加作为重叠区域中的特定用户设备的密度信息。此外, 也可以将所述第一密度信息和第二密度信息通过其他一些加权计算的方式获得所述重叠区域的特定用户设备的密度信息。
对于非重叠区域(例如对应于其他子区域和/或子区域的其他部分),所述第一无线通信***和第二无线通信***可通过各自的获取单元101分别获取各自重叠区域之外区域的与分布有关的用户特征。
具体地,请参阅图2,某一场景中,所述第一无线通信***服务的区域与第二无线通信***服务的区域仅部分重叠,密度信息可能在该区域的各个部分中并不相同。如图2所示,其中,A是第一无线通信***服务的区域,B是第二无线通信***服务的区域,C是第一无线通信***和第二无线通信***共同服务的区域(即重叠区域)。对于区域C而言,特定用户设备不仅包括第一无线通信***的特定用户设备而且包括第二无线通信***的特定用户设备,因此,C中的用户设备密度可能与A中除了C以外的其他部分的用户设备密度不同。
当一个区域同时由多个无线通信***来服务时,该多个无线通信***的获取单元101之间可直接交互来获取所述用户特征。此外,在一个示例中,多个无线通信***可通过一中央管理装置来协调一个区域内的通信操作,从而多个无线通信***的获取单元101可通过所述中央管理装置来交互各自无线通信***获取的与分布有关的用户特征。例如,该中央管理装置统一管理区域或子区域中与分布有关的用户特征并提供给各个通信***的获取单元。
由于特定用户设备在所述无线通信***所服务区域的分布可能不断改变,因此所述与分布有关的用户特征可能会在不同时间段内相应的变化,从而,所述获取单元101可进一步被配置为定期更新所述区域内与特定用户设备的有关的用户特征。如上所述,当一个区域内同时包括所述第一无线通信***和第二无线通信***时,类似地,所述获取单元101可进一步被配置为定期更新所述第一用户特征和第二用户特征。
进一步地,所述获取单元101被配置为基于如下方式中的至少一个进行更新:响应于每一个特定用户设备的接入操作和断开操作来更新,定期更新。例如,在与分布有关的用户特征用特定用户设备的密度表示的情况下,获取单元101通过统计单位面积内的特定用户设备的数量来获得密度信息,并且在该数量改变时以及/或者周期性地相应地更新密度 信息。具体地,当发生特定用户设备的接入或断开操作时,特定用户设备的数量改变。每一个特定用户设备的接入操作包括特定用户设备在上述区域内启动以及切换进入该区域。相应地,每一个特定用户设备的断开操作包括特定用户设备在上述区域内关闭以及切换离开该区域。而在周期性地更新时,更新的周期决定了密度信息的准确性。
在与分布有关的用户特征用区域内单位时间内发送信息的特定用户设备的密度来表示的情况下,获取单元101例如可以响应于特定用户设备的通信状态(例如,开始发送信息或停止发送信息)的改变而更新密度信息以及/或者定期更新密度信息。同样,在周期性地更新时,更新的周期决定了密度信息的准确性。
通过更新与分布有关的用户特征,获取单元101可以准确地获取该用户特征,从而使得随后将要描述的确定单元102能够实现无线传输资源的时间上的动态划分。
确定单元102根据获取单元101所获取的用户特征来确定特定用户设备要使用的无线传输资源池中的资源的划分。其中,无线传输资源池是分配给特定用户设备使用的无线传输资源的集合,该集合可以划分为若干份,能够分别由多个特定用户设备同时使用。
其中,无线传输资源池可以在频谱维度上进行划分,例如按照一划分粒度在频谱维度上划分为多个基本资源单位,每一个特定用户设备可以使用一个基本资源单位进行通信。例如,每一个特定用户设备可以对基本资源单位进行随机使用。
在一示例中,当区域中特定用户设备的分布较为密集比如密度较高时,所述确定单元102可对所述无线传输资源池中的资源采用较细的划分粒度来划分,从而可满足尽可能多的特定用户设备对无线传输资源的需求,反之,当区域中特定用户设备的分布较为稀疏比如密度较低时,所述确定单元102可对所述无线传输资源池中的资源采用较粗的划分粒度来划分,以使得每一个特定用户设备可以占用较多的传输资源来传输。通过利用划分粒度的设置,可以根据使用无线传输资源的特定用户设备的数量来调整无线传输资源的划分,从而在保证通信质量的同时实现较高的资源利用效率,并且有效地降低了特定用户设备选择资源的时间。
进一步地,在一个示例中,所述确定单元102基于区域中的所述用户特征以及消息的准入率来确定所述无线传输资源池中的资源的划分。其中,消息的准入率为基本资源单位的数量与同时到达的消息数(即,要同时使用无线传输资源的特定用户设备的数量)的比值。由于基于用户特征和消息准入率两个因素来进行无线传输资源池的划分,可以在保证资源利用效率的同时确保一定的用户设备接入成功率,而且更进一步减小信息交互的延迟,减小选择可用传输资源以及目标用户正确接收信息的时延,降低信息交互的信令开销。
具体地,划分粒度被设置为使得区域中特定用户设备的密度越大,消息的准入率越高,划分粒度越细。在无线传输资源池的大小固定的情况下,划分粒度越细,则基本资源单位的数量越多,从而能够同时供更多的特定用户设备使用。
作为一个示例,划分粒度可以以如下方式设置:在保证特定用户设备的通信质量和消息的准入率维持在预定水平的条件下,基本资源单位的数量最少。其中,通信质量例如可以用信干噪比表示。由于上述两个约束条件,划分粒度的设置最终成为一优化问题,其可以使用各种优化算法实现,包括但不限于线性规划、博弈论、图论等。通过以该方式设置划分粒度,可以基于通信***的特点合理地实现无线传输资源池的划分,并且显著降低特定用户设备使用无线传输资源的时延,同时保持较高的无线资源利用率以及保证特定用户设备的通信质量。
为了简化信令的传输,可以设置为使得划分粒度与无线传输资源池中基本资源单位的配置方案一一对应。换言之,在装置100与特定用户设备之间事先约定划分粒度与在每一种划分粒度下每一个基本资源单位在频谱维度上的起始和结束位置的对应关系,这种事先约定例如可以写入用户设备的出厂设置,或者在用户设备开机时通过自动设置实现,或者通过装置100与特定用户设备之间的信令来实现。这样,当特定用户设备获知划分粒度时,即可获知每一个基本资源单位的具体配置。
当特定用户设备在区域中的分布发生变化时,为了保持准确性,确定单元102需要重新计算资源的划分。因此,确定单元102可以被配置为周期性地计算该资源的划分,以及/或者在所获取的分布的变化超过预定范围时计算该资源的划分。例如,可以将用户设备的密度分为多个等 级,当密度在等级之间变化时,重新计算资源的划分;以及/或者可以每隔预定时间重新计算资源的划分。如前所述,该资源的划分可以为无线传输资源池在频谱维度上的划分粒度。通过上述方式,可以减小资源重新分配以及***重配置的频度。
应该理解,为了获得更高的灵活性,取决于实际的应用场景,也可以将基本资源单位划分为互不相等的。
另一方面,返回参照图2所示,由于C中的用户设备密度可能与A中除了C以外的其他部分的用户设备密度不同,因此确定单元102为其确定的资源的划分也可能不同。例如,当特定用户设备从其他部分移动到部分C时,可能会发生资源的划分的改变。因此,无线传输资源池中资源的划分的除了具有时间上的动态属性外还具有空间上的动态属性。如前所述,当所述区域被划分成多个所述子区域时,所述确定单元102可进一步根据每个子区域的用户特征来确定每个子区域中的特定用户设备要使用的无线传输资源的划分。
进一步地,请参阅图1,所述装置100还可以包括收发单元103,该收发单元103被配置为向所述特定用户设备发送所述确定单元102确定的所述划分的信息。在这种情况下,特定用户设备接收到划分的信息,从而可以根据该信息来自行选择传输资源。划分的信息例如可以包括无线传输资源池在频谱维度上的划分粒度。
此外,收发单元103还可以在划分发生变化时,向特定用户设备通知该变化。替选地/附加地,收发单元103也可以周期性地向特定用户设备通知划分的变化。
进一步地,当区域中有多个无线通信***所服务时,多个无线通信***的获取单元102可以通过各自的收发单元103来交互所述与分布有关的用户特征。
在另一个示例中,装置100的收发单元103也可以不向特定用户设备通知划分的信息,而是由装置100根据该划分直接为特定用户设备进行资源分配并通过下行信息通知特定用户设备,此时特定用户设备不需要获知有关划分的信息。
在前述划分粒度与无线传输资源池中基本资源单位的配置方案一一 对应的示例中,由于仅需要向特定用户设备通知划分粒度,信息量小,信令简单。此外,为了获得更高的灵活性,除了划分粒度以外,也可以在划分信息中包括更多的内容比如具体的配置方案等。当基本资源单位被设置为互不相等时,相应的划分的信息的内容也会改变。
进一步地,请参阅图1,所述装置100还可以包括存储单元104,所述存储单元104被配置为存储和更新区域(或子区域)中所述特定用户设备的与分布有关的用户特征。所述获取单元102可以进一步被配置为查询所述存储单元104中的用户特征。在这种情况下,无线通信***保存自身所服务的特定用户设备的与分布有关的用户特征。
通过上述设置,可以实现跨运营商或跨通信***的与分布有关的用户特征的交互,从而使得可以在对无线传输资源的利用上相互协调,提高利用效率,并且降低信息交互的延迟和信令开销。此外,资源利用上的相互协调也有利于实现多***共存。
所述装置100中的获取单元101以及确定单元102可通过一个或多个处理电路来实现。
<第二实施例>
下面参照图3描述根据本申请的一个实施例的用于无线通信***中的用户设备侧的装置200的结构框图,装置200包括:请求生成单元201,被配置为生成包含标识该用户设备的设备类型的连接请求;以及选择单元202,被配置为根据从网络管理装置接收到的基于连接请求的、关于无线传输资源池的划分的信息来选择要使用的资源。
装置200所在的用户设备属于特定类型的用户设备,请求生成单元201在生成连接请求时将该类型的信息包括在其中,以使得网络管理装置比如基站能够获知该用户设备的类型。类似地,本实施例中的特定用户设备例如可以为车联网用户设备或者在SAS中具有优先访问许可证的无线通信***的用户设备。网络管理装置例如可以基于该类型信息来更新其服务区域中属于该类型的特定用户设备的与分布有关的用户特征,根据该用户特征来确定特定用户设备要使用的无线传输资源池的划分,并将该划分的信息传递给用户设备。此外,该连接请求中还可以包括用户 设备的位置信息,以便于网络管理装置比如基站判断该用户设备所在的区域或子区域,从而可以获得更精确的与分布有关的用户特征并进一步更优地确定无线传输资源的划分。
选择单元202根据该划分的信息来选择要使用的资源,例如通过随机选取资源以及频谱感知来找到可供使用的资源。在一个示例中,也可以由网络管理装置直接为用户设备进行资源分配。
其中,划分的信息可以包括无线传输资源池在频谱维度上的划分粒度,其中,无线传输资源池按照该划分粒度划分为多个基本资源单位,选择单元202利用频谱感知找到可以使用的基本资源单位。具体地,选择单元202可以随机选择一个基本资源单位进行频谱感知,如果其空闲则使用该基本资源单位进行通信,否则再次随机选择另一个基本资源单位进行频谱感知,直到找到空闲的基本资源单位为止。
为了简化信令,可以将划分粒度与无线传输资源池中基本资源单位的配置方案设置为一一对应。在这种情况下,所接收的划分的信息仅需包括划分粒度的信息,选择单元202即可根据划分粒度来确定具体的划分方式进而选择其中的一个基本资源单位来进行通信。
如图3中的虚线框所述,装置200还可以包括:收发单元203,被配置为向网络管理装置发送连接请求以及从网络管理装置接收划分的信息。
当用户设备位于不同的区域时,所接收的划分的信息可能不同。例如,当用户设备位于不同的小区时,或者位于同一小区的不同位置比如图2中所示的区域C和区域A的除C以外的区域时,资源的划分可能不同。
此外,在划分改变的情况下,收发单元203也可以从网络管理装置接收划分信息的改变,从而选择单元202基于改变的划分信息来选择要使用的资源。
<第三实施例>
图4示出了根据本申请的一个实施例的用于多个无线通信***的中 央管理装置300的结构框图,如图4所示,该中央管理装置300包括:获取单元301,被配置为获取所管理的每一个无线通信***中特定用户设备的与分布有关的用户特征的信息;计算单元302,被配置为根据获取单元301所获取的用户特征的信息来计算特定用户设备要使用的无线传输资源池中的资源的划分;以及通知单元303,被配置为向多个无线通信***通知资源的划分的信息。
在该实施例中,中央管理装置300不仅从所管理的每一个无线通信***获取特定用户设备的与分布有关的用户特征,而且根据该用户特征来计算无线传输资源的划分并向每一个无线通信***通知该划分。即,与第一实施例相比,中央管理装置300的计算单元302执行了确定单元102的功能,从而可以简化网络管理侧的操作。
其中,用户特征的信息可以用特定用户设备的密度信息来表示。密度例如通过单位区域内的用户设备数来表示。密度信息的更新可以响应于每一个特定用户设备的接入操作和断开操作进行以及/或者定期进行。计算单元302在进行计算时例如可以将各个无线通信***的用户设备的密度加和来获得相应区域中最终的用户设备密度。此外,与分布有关的用户特征还可以用区域内单位时间内发送信息的特定用户设备的密度来表示。类似地,此时的密度为单位区域内单位时间内发送信息的特定用户设备的数量,并且可以响应于特定用户设备的通信状态(例如,开始发送信息或停止发送信息)的改变而更新以及/或者定期更新。
计算单元302可以周期性地计算划分以及/或者在用户特征的信息的变化超过预定范围时计算划分。计算单元302可以与第一实施例中确定单元102类似地实现,具体的计算方法将根据实际应用场景和通信***模型而改变。
作为一个示例,划分的信息包括无线传输资源池在频谱维度上的划分粒度,其中,无线传输资源池按照划分粒度划分为多个基本资源单位,每一个特定用户设备使用一个基本资源单位进行通信。如前所述,划分粒度与特定用户设备的密度有关。划分粒度可以被设置为使得区域中特定用户设备的密度越大,消息的准入率越高,划分粒度越细。具体地,划分粒度可以以如下方式设置:在保证特定用户设备的通信质量和消息的准入率维持在预定水平的条件下,基本资源单位的数量最少。其中, 通信质量例如可以用信干噪比表示。通过基本资源单位的数量最少,可以尽可能地降低信息传递的延迟,尤其适合于数据传输实时性要求高的场合。划分粒度的计算最终成为一优化问题,其可以使用各种算法实现,包括但不限于线性规划、博弈论、图论等。
类似地,本实施例中的特定用户设备例如可以为车联网用户设备或者在SAS中具有优先访问许可证的无线通信***的用户设备。
<第四实施例>
下面将以车联网和频谱访问***为应用示例描述本技术的应用。
如前所述,车联网的建立是为了传递和分享安全信息,由于安全信息的特殊性,因此希望在通信***内以及在不同的通信***间建立低延迟的信息渠道,即实现跨运营商的低延迟信息交互。在该示例中,特定用户设备例如为支持V2V业务的车辆或车辆上的通信设备。
图5示出了一个十字路口的车联网的车辆的示意性分布图。首先,假设在图5所示的区域中仅有唯一运营商A提供V2V业务服务,装置100例如可以设置在图5所示的eNB上,在第一实施例中所描述的装置100的细节均可以适用于本实施例,此处不再重复。
图6示出了车辆V与eNB之间的信息交互的流程。如图6所示,车辆V通过向eNB发送V2V设备连接请求而接入eNB,其中在连接请求中向eNB指示其为V2V设备。示例性地,车辆V中可以设置有第二实施例所述的装置200。
eNB中的装置100在识别出该车辆为V2V设备后,(具体地,例如由存储单元104)更新其管理的车辆密度信息。该车辆密度信息可以设置为eNB服务范围内接入的V2V设备数量/道路面积。
其中,道路面积可以采用下述估算方法之一获得:从交通管理部门获取实际道路分布勘测结果,利用其数据进行准确计算;利用一些道路分布的基本模型和参数假设,对于一定地理范围内的道路面积进行粗略估计,例如,图7示出了道路分布设定,包括道路长、宽、间隔区域等等参数,根据这些参数可以估算出单位地理面积内的道路面积占比,从 而得到任意地理面积内的道路面积。
接着,装置100向车辆V发送资源的划分的信息,或者装置100此时可以不发送划分的信息而直接执行下述的操作。即,装置100(具体地,确定单元102)例如还根据车辆密度信息的变化是否超出预定范围以及/或者距离上次重新计算是否经过了预定时间,而决定是否重新计算资源的划分,如果车辆密度信息的变化超出预定范围或者距离上次重新计算经过了预定时间,则确定单元102根据变化后的密度信息重新确定划分,并且装置100(具体地,收发单元102)通过下行信息向车辆V通知更新后的划分的信息。注意,当划分改变时,装置100需要向所有已经连接的V2V设备发送该划分的改变,以使得这些V2V设备重新进行资源的选择。
此外,如图6所示,当车辆V断开与eNB的连接比如关机或驶出eNB的覆盖范围时,除了通常的操作之外,装置100也需要更新其管理的车辆密度信息并且在必要时重新计算资源的划分。
注意,由于V2V业务中要传递的安全信息通常为固定长度的信息,因此为了降低划分的复杂性以及降低碰撞概率,可以将整个无线传输资源池在频谱维度上均分为多个基本资源单位。这样,可以将划分粒度与具体的划分方式一一对应,从而可以将对应粒度的划分方式提前配置在V2V设备中,V2V设备仅根据粒度的指示即可获知其具体划分。
在根据密度信息进行资源划分粒度的计算时,具体方式与资源的分配方法密切相关。下面以一种保证公平的分布式资源分配方法为例进行描述。假设资源池的频谱宽度为B,被平均分为NR个基本资源单位,每个资源单位的宽度记作Δ=B/NR,任一V2V设备等概率地随机从中选择一个资源单位i,该V2V设备对i进行频谱感知,若其空闲则占用并发送信息;否则,再随机选择下一个资源单位j,以此循环直到找到可供使用的资源。
返回参照图5所示的分布图,设图中任一边长为r的虚线方框内NR个基本资源单位恰好均被无重复地使用一次。不失一般性,资源单位i的接收车辆恰好位于圆心o,其发射车辆和接收车辆距离为车辆平均距离d,于是接收车辆收到的信号强度为与距离d相关的函数S(d),其中函数S(*)由具体的信道模型决定,这些信道模型可以采用已有的各种模型, 在此不再赘述。相邻的4个虚线方框也具有相同的分布,则复用资源单位i的发射源位于各虚线方框中心为原点,d为半径的圆内,当r>>d时,可以近似位于圆心处,所以接收车辆受到的干扰为
Figure PCTCN2017071100-appb-000001
又由于十字路口的地理位置的特殊性,可以假设四个方向均有一个干扰源车辆,即n=4。为了保证接收车辆能够正确解码信号,必须保证其信干噪比SINR超过一定的阈值SINRTH,如下文中的不等式(2)所示。
另一个***性能要求必须保证消息的准入率ρ超过一定的阈值ρTH,如不等式(3)所示,如前所述,消息的准入率ρ定义为基本资源单位的数量NR与消息数NM的比值。消息数NM的计算如等式(4)所示,其中,A(r)表示圆内道路面积,λV表示车辆密度,θM为每辆车的消息平均到达间隔时间,T(Δ,LM,fM)表示每条消息传输的总时间,其可以进一步表示为基本资源单位宽度Δ、每条消息平均长度LM以及每条消息发送平均频度fM的复合函数,该函数和具体的无线通信***有关,函数
Figure PCTCN2017071100-appb-000002
为上取整。优化目标为在满足(2)~(4)的条件下,求NR的最小值,如式(1)所示。即,使得基本资源单位的数量最小,这是为了减少在资源池上进行信息接收的设备盲检所需的时间,即降低安全信息传输的延迟。

应该理解,以上仅是一种划分粒度的示例性计算方法,本申请不限于此,而是可以根据具体的应用场景下的用户设备分布、信道模型、用户设备到达、业务到达等不同地计算。例如,在以上的计算中作为干扰源的V2V设备假定是均匀分布的,但是也可以考虑V2V设备不均匀分布的情况下,这时需要根据干扰源的位置来计算干扰。
在另一个示例中,图5所示的区域中可以存在多个运营商,比如运营商A和运营商B共同提供V2V业务。假设车辆a接入运营商A的eNB-A,车辆b接入运营商B的eNB-B。在这种情况下,除了以上在单运营商情况下描述的各个操作之外,还需要在获取车辆密度信息时考虑其他运营商所服务的车辆的密度信息。图8示出了同一区域中存在多个 运营商的情况下的信令流程的示意图。如图8所示,与图6类似地,eNB-A和eNB-B在识别出车辆a和车辆b为V2V设备后,分别更新其管理的车辆密度信息。因此,覆盖同一区域的eNB-A和eNB-B交互各自的车辆密度信息λV,a和λV,b。eNB-A和eNB-B计算该区域的车辆密度如下λV=λV,aV,b,并根据该密度信息分别计算划分粒度。在计算时,仍然可以采用上述单运营商情形下所使用的计算方法,在此不再重复。其中,eNB之间车辆密度信息的交互可以是响应于每一个特定用户设备的接入操作和断开操作的,以及/或者是定期进行的。
或者,eNB-A和eNB-B可以将各自的车辆密度信息λV,a和λV,b报告给中央管理装置(也可以称为协调设备),该中央管理装置协调区域中多个无线通信***的操作,例如计算该区域中总的车辆密度λV=λV,aV,b并将其提供给各个无线通信***的网络管理侧装置比如eNB。
此外,还可以采用比如第三实施例中所述的中央管理装置300,以进一步基于总的车辆密度来计算资源池的划分。图9示出了采用中央管理装置来计算划分粒度的信息流程的示意图,如图9所示,eNB-A和eNB-B分别向中央管理装置上报其车辆密度信息,中央管理装置例如基于这些车辆密度信息来获得区域中总的车辆密度,根据该总的车辆密度来重新计算资源池的划分比如划分粒度,并将更新后的划分的信息提供给每一个eNB,然后由eNB发送给其服务的车辆。
注意,在这种情况下,中央管理装置还从各个无线通信***收集在计算划分粒度的过程中所需的各种信息。划分粒度的计算方式可以与上述仅存在单个无线通信***的情况下的计算方式相同,在此不再重复。
应该理解,虽然这里以车辆密度作为用户设备的与分布有关的用户特征,但是也可以替代地/补充地采用其他分布特征,比如所述分布特征可以为所述区域中单位时间内发送信息的特定用户设备的密度,或者实际的用户设备的空间分布。在采用其他分布特征的情况下,对于资源的划分的计算将会相应地改变。并且,虽然示出了存在两个运营商的情形,但是以上描述同样可以应用于更多个运营商的情形。
以上虽然以车联网为应用场景描述了本技术,但是本技术的应用并不限于此,而是可以应用于任何支持多***共存的资源管理场景。作为另一个示例,以下将描述其在频谱访问***(SAS)3.5GHz***多层次 共存***管理中的应用。
在美国,3.5GHz频带一直用于国防部雷达***,目前联邦通信委员会(Federal Communications Commission,FCC)在讨论将该频段通过频谱共享的方式用于商用。该共享***是SAS的一部分,包含三个等级:责任(incumbent)用户等级,代表最高等级,需要保护其不受公民宽带无线服务用户的有害干扰,责任用户包含上述国防部雷达***、固定卫星服务、以及有限时间内的特权陆地无线业务;公民宽带无线服务的优先访问许可证(priority access license,PAL)等级;以及公民宽带无线服务的普通授权访问(General Authorized Access,GAA)等级,其中需要保护PAL不受到来自GAA的有害干扰。公民宽带无线服务可以以人口普查区为单位进行资源分配,PAL例如以10MHz为单位以3年为期限发放,每个人口普查区的所有PAL所占总频谱不超过70MHz,其中每个PAL的频谱不超过40MHz。GAA在保证不对各个高级别用户产生有害干扰的前提下,可以使用3550-3650MHz范围内的频谱。
可以看出,PAL提供了一种具有时效性的排他访问模式。但是,当一个人口普查区内多个PAL的用户数量分布不均衡时,比如某一个PAL的用户数很多而其他PAL的用户数非常少,可能需要在多个PAL间共享资源,从而更加有效地保证资源的利用率。
假设存在两个优先访问许可证持有者PAL-A和PAL-B,其分别为各自的用户UE-a和UE-b提供业务。在一个示例中,可以将第一实施例中的装置100设置在PAL-A和PAL-B的网络管理侧,即由PAL-A和PAL-B分别计算资源的划分。应该理解,在第一实施例中所描述的装置100的细节均可以适用于本示例,此处不再重复。
UE-a和UE-b分别接入PAL-A和PAL-B并例如在连接请求中指示其业务类型。装置100例如响应于该接入来更新与该业务类型相关的用户设备的分布特征比如用户密度λV,a和λV,b。类似地,在两个PAL之间交互各自的用户密度信息,从而得到总的用户密度λVV,aV,b。装置100在密度的改变超过预定范围时以及/或者从上次重新计算经过了预定时间时重新计算划分粒度,以将新的划分粒度提供给接入的用户设备。相关的信息流程如图10所示,与图8类似,在此不再详述。
此外,也可以设置中央管理装置来协调PAL-A和PAL-B的操作。 在这种情况下,PAL-A和PAL-B可以将各自的密度信息λV,a和λV,b报告给中央管理装置,并且由中央管理装置来计算划分粒度并向PAL-A和PAL-B通知划分粒度或其改变,相关的信息流程如图11所示,与图9类似,在此不再详述。在频谱访问***中,中央管理装置例如可以位于地理位置数据库或频谱管理装置中。
其中,划分粒度的具体计算可以使用与以上参照图3所描述的方法类似的方法,只是干扰的计算略有不同。图12示出了一个人口普查区的分布图,设图中任一边长为r1的虚线方框内表示一个人口普查区,每个人口普查区都复用SAS 3.5GHz***里的NR个基本资源单位,其中,NR个基本资源单位由PAL-A和PAL-B所对应的资源在频谱维度上划分获得。图12与图5的差异在于接收用户受到的干扰的计算,由于网格分布的地理位置的特殊性,可以假设八个相邻网格均有一个干扰源用户,总干扰数为n=8。其中4个与中心方格边相邻的区域干扰计算为
Figure PCTCN2017071100-appb-000006
4个与中心方格点相邻的区域干扰计算为
Figure PCTCN2017071100-appb-000007
因此总的干扰为
Figure PCTCN2017071100-appb-000008
其他计算仍可采用式(1)至(4)进行。
通过基于用户设备的空间分布在PAL-A和PAL-B甚至更多个PAL之间共享资源,能够更加有效地保证资源的利用率。
应该理解,以上虽然以车联网和频谱访问***为例描述了本技术,但是本技术的应用范围不限于此,而是可以应用于任何多个用户设备共享传输资源的场合。
<第五实施例>
在上文的实施方式中描述无线通信***中的网络管理侧和用户设备侧的装置以及中央管理装置的过程中,显然还公开了一些处理或方法。下文中,在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要,但是应当注意,虽然这些方法在描述无线通信***中的网络管理侧和用户设备侧的装置以及中央管理装置的过程中公开,但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如,无线通信***中的网络管理侧和用户设备侧的装置以及中央管理装置的实施方式可以部分地或完全地使用硬件和/或固件来实现,而下面讨论的方法可 以完全由计算机可执行的程序来实现,尽管这些方法也可以采用无线通信***中的网络管理侧和用户设备侧的装置以及中央管理装置的硬件和/或固件。
图13示出了根据本申请的一个实施例的用于无线通信的网络管理侧的方法的流程图。该方法包括:获取无线通信***所服务的区域中的特定用户设备的与分布有关的用户特征(S11);以及根据所获取的用户特征来确定特定用户设备要使用的无线传输资源池中的资源的划分(S13)。
其中,在步骤S11中,如果在区域内只有一个无线通信***,则可以直接获得上述用户特征。否则,当在区域内存在两个或更多个无线通信***时,特定用户设备包括第一无线通信***服务的第一特定用户设备和第二无线通信***所服务的第二特定用户设备,第二无线通信***所服务的区域与第一无线通信***所服务的区域至少部分重叠,针对重叠区域,获取第一特定用户设备的与分布有关的第一用户特征以及第二特定用户设备的与分布有关的第二用户特征,并结合第一用户特征和第二用户特征以获得重叠区域中的特定用户设备的与分布有关的用户特征。在一个示例中,可以从第二无线通信***获取第二用户特征。此外,还可以向第二无线通信***提供第一用户特征。
用户特征包括第一用户特征和第二用户特征可以分别以如下方式中的至少一个进行更新:响应于每一个特定用户设备的接入操作和断开操作来更新,定期更新。
如图13中的一个虚线框所示,上述方法还可以包括步骤S12:存储和更新特定用户设备的与分布有关的用户特征,其中,在步骤S11中,可以通过查询所存储的用户特征来进行获取。
另一方面,在步骤S11中还可以从中央管理装置接收与分布有关的用户特征,中央管理装置协调区域中多个无线通信***的操作。
作为示例,特定用户设备的用户特征可以用区域中特定用户设备的密度信息来表示。或者,特定用户设备的用户特征可以用区域中单位时间内发送信息的特定用户设备的密度信息来表示。
在步骤S13中,根据步骤S11中的分布特征来划分无线传输资源池 中的资源。例如,可以按照某一划分粒度在频谱维度上将无线传输资源池划分为多个基本资源单位,每一个特定用户设备使用一个基本资源单位进行通信,该使用可以是随机的。划分粒度可以被设置为与无线传输资源池中的基本资源单位的配置方案一一对应。
划分粒度可以被设置为使得区域中特定用户设备的密度越大,消息的准入率越高,划分粒度越细。例如,划分粒度以如下方式设置:在保证特定用户设备的通信质量和消息的准入率维持在预定水平的条件下,基本资源单位的数量最少,这样可以尽可能降低信息传输的延迟。
其中,步骤S13中的资源的划分可以是周期性地进行的,以及/或者在所获取的分布的变化超过预定范围时进行的。
如图13中的另一个虚线框所示,上述方法还可以包括步骤S14:向特定用户设备发送确定单元确定的划分的信息。在一个示例中,划分的信息包括无线传输资源池在频谱维度上的划分粒度。
图14示出了根据本申请的一个实施例的用于无线通信***中的用户设备侧的方法的流程图。该方法包括如下步骤:生成包含标识该用户设备的设备类型的连接请求(S21);以及根据从网络管理装置接收到的基于所述连接请求的、关于无线传输资源池的划分的信息来选择要使用的资源(S24)。
如图14中的虚线框所示,上述方法还包括如下步骤:向网络管理装置发送连接请求(S22);以及从网络管理装置接收划分的信息(S23)。
其中,划分的信息可以包括无线传输资源池在频谱维度上的划分粒度,其中,无线传输资源池按照所述划分粒度划分为多个基本资源单位,在步骤S24中利用频谱感知找到可以使用的基本资源单位。例如,划分粒度与无线传输资源池中基本资源单位的配置方案可以一一对应。其中,划分粒度的设置已经在前述实施例中进行了详细的描述,在此不再重复。
当用户设备位于不同的区域时,划分的信息可能不同。
图15示出了根据本申请的一个实施例的用于多个无线通信***的中央管理方法,包括:获取所管理的每一个无线通信***中特定用户设备的与分布有关的用户特征的信息(S31);根据所获取的用户特征的信息来计算特定用户设备要使用的无线传输资源池中的资源的划分(S32); 以及向多个无线通信***通知资源的划分的信息(S33)。
其中,用户特征的信息可以用特定用户设备的密度信息来表示。步骤S32可以周期性地执行以及/或者在用户特征的信息的变化超过预定范围时执行。
划分的信息可以包括无线传输资源池在频谱维度上的划分粒度,其中,无线传输资源池按照该划分粒度划分为多个基本资源单位,每一个特定用户设备使用一个基本资源单位进行通信。划分粒度可以被设置为使得区域中特定用户设备的密度越大,消息的准入率越高,划分粒度越细。
在步骤S32中可以以如下方式计算划分粒度:在保证特定用户设备的通信质量和消息的准入率维持在预定水平的条件下,基本资源单位的数量最少。
其中,上述特定用户设备可以为车联网用户设备或者在频谱访问***中具有优先访问许可证的无线通信***的用户设备。
注意,上述各个方法可以结合或单独使用,其细节在第一至第三实施例中已经进行了详细描述,在此不再重复。
