Description

资源调度方法及装置 技术领域
本发明涉及通信技术领域,特别涉及一种资源调度方法及装置。
背景技术
在通信领域,LTE(Long Term Evolution,长期演进)系统普遍采用同频组网,致使小区间干扰较为严重,特别是在站点密度大的网络,干扰更为明显。LTE系统一般采用多RRU(Remote Radio Unit,拉远射频单元)共小区技术进行资源调度,以降低密集布站时的干扰并获得合并增益。
基于多RRU共小区技术,目前在进行资源调度时,先将多个RRU组成一个逻辑小区,并通过测量逻辑小区内每个UE(User Equipment,用户设备)到达小区中各个RRU的上行RSRP(Reference Signal Receiving Power,参考信号接收功率),确定出每个UE的干扰强度,进而根据每个UE的干扰强度,确定每个UE的用户属性,该用户属性为全部联合调度UE、部分联合调度UE及独立调度UE,从而根据每个UE的用户属性,对每个UE进行资源调度。当UE的用户属性为全部联合调度UE,逻辑小区内的所有UE合并为一个服务RRU,对UE的资源进行调度;当UE的用户属性为部分联合调度UE,逻辑小区内干扰较强的部分UE合并为一个服务RRU,对UE的资源进行调度;当UE的用户属性为独立调度用户,逻辑小区内干扰最弱的RRU作为UE的服务RRU,对UE的资源进行调度。
在实现本发明的过程中,发明人发现相关技术至少存在以下问题:
相关在进行资源调度时,对不同用户的用户属性进行确定时主要依赖于测量信号的条件和干扰强度,且对具有不同用户属性的用户进行处理时缺乏区分度,导致小区间干扰较为严重,资源利用效率不高。

上述所有可选技术方案,可以采用任意结合形成本发明的可选实施例,在此不再一一赘述。
结合上述图3所示的实施例,本发明实施例提供了一种资源调度方法,以对当前待调度的UE进行资源调度为例,参见图4,本实施例提供的方法流程包括:
401:获取UE的初始用户属性。
由于初始用户属性能够反应出当前待调度的UE与其他UE间的干扰情况,为对当前待调度的UE进行资源调度的重要参考,因此,本实施例提供的方法在进行资源调度之前,需要先获取当前待调度UE的初始用户属性。其中,初始用户属性为全部联合调度用户、部分联合调度用户和独立调度用户等,本实施例不对初始用户属性作具体的限定。
在LTE系统中为了降低小区间的干扰,通常将多个独立的RRU合并为一个逻辑小区。基于多个RRU组成的逻辑小区,在确定UE的初始用户属性时,包括但不限于:根据为每个UE提供服务的RRU的数量,确定每个UE的用户属性。具体地,当由多个RRU组成的逻辑小区内的所有的RRU均为UE提供服务,则确定UE的初始用户属性为全部联合调度用户;当由多个RRU组成的逻辑小区内的部分RRU为UE提供服务,则确定UE的初始用户属性为部分联合调度用户;当由多个RRU组成的逻辑小区内的一个RRU为UE提供服务,则确定UE的初始用户属性为独立调度用户。
关于确定为每个UE提供服务的RRU的数量方式,包括但不限于如下方式:获取UE的位置信息,根据UE的位置信息,确定为UE提供服务的RRU的数量。具体地,若UE与所有RRU之间的距离都小于第一预设距离,则确定所有的RRU均为UE提供服务,此时UE的初始用户属性为全部联合调度用户;若UE与部分RRU之间的距离小于第一预设距离,则确定部分RRU为UE提供服务,此时UE的初始用户属性为部分联合调度用户;若UE与一个RRU之间的距离小于第一预设距离,则确定一个RRU为UE提供服务,此时UE的初始用户属性为独立联合调度用户。其中,第一预设距离可以为30米、50米等,本实施例不对第一预设距离作具体的限定。
另外,除了采用上述方式确定为每个UE提供服务的RRU的数量之外,还可以根据干扰强度信息进行确定。当UE与所有RRU的干扰强度都大于第一预设阈值时,则确定所有的RRU均为UE提供服务,此时UE的初始用户属性为全部联合调度用户;当UE与部分RRU的干扰强度大于第一预设阈值时,则确定部分RRU为UE提供服务,此时UE的初始用户属性为部分联合调度用户;当UE与一个RRU的干扰强度大于第一预设阈值时,则确定一个RRU为UE提供服务,此时UE的初始用户属性为独立联合调度用户。其中,第一预设阈值可以为1、2、3等,实施例不对第一预设阈值作具体的限定。
为了便于理解上述过程,下面将以一个具体的例子进行详细地解释说明,
图5为由多个RRU组成的逻辑小区的示意图。由图5可知,逻辑小区内有三个RRU,分别为RRU1、RRU2和RRU3,逻辑小区内有四个UE,分别为UE1、UE2、UE3、UE4。若为UE1提供服务的RRU为RRU1和RRU2,为UE2提供服务的RRU为RRU1、RRU2和RRU3,为UE3提供服务的RRU为RRU1,为UE4提供服务的RRU为RRU2,则确定UE1为部分联合调度用户,UE2为全部联合调度用户,UE3为独立调度用户,UE4为独立调度用户。
402:确定为UE提供服务的各个RRU,获取由各个RRU组成的工作RRU集合。
由于每个UE所处的位置和信号条件不同,因此,逻辑小区内为每个UE提供服务的RRU也是不同的。若UE与逻辑小区内所有RRU的距离均小于第二预设距离,且所有RRU间干扰较为严重,则将所有的RRU作为UE的服务RRU,并将所有RRU组成的集合作为UE的工作RRU集合;若UE与逻辑小区内部分RRU的距离小于第二预设距离,且这些RRU与其他RRU间干扰较为严重,则将这些RRU作为UE的服务RRU,并将这些RRU的组成的集合作为UE的工作RRU集合;若UE与逻辑小区内一个RRU的距离小于第二预设距离,且该RRU与其他RRU间干扰并不严重,则将该RRU作为UE的服务RRU,并将该RRU组成的集合作为UE的工作RRU集合。其中,第二预设距离可以为10米、20米、50米等,本实施例不对第二预设距离作具体的限定。
403:根据UE到工作RRU集合中各个RRU的RSRP,确定UE的信号强度最大RRU。
其中,RSRP在LTE网络中可以代表无线信号强度的关键参数以及物理层测量需求之一,为在某个符号内承载参考信号的所有RE(资源粒子)上接收到的信号功率的平均值。RSRP的单位为dbm。在本实施例中,信号强度最大RRU为UE接收到信号最强的RRU。
关于根据UE到工作RRU集合中各个RRU的RSRP,确定UE的信号强度最大RRU的方式,包括但不下限于:
首先,接收UE发送的携带UE到达工作RRU集合中各个RRU的RSRP的测试报告。
其次,将UE到达工作RRU集合中RSRP最大的RRU作为信号强度最大RRU。
对于上述过程,为了便于理解,下面将以一个具体的例子进行详细地解释说明。
例如,设定任意一个UE的工作RRU集合中有四个RRU,分别为:RRU1、RRU2、RRU3、RRU4。若测量出UE到RRU1的RSRP为3dbm,UE到RRU2 的RSRP为6dbm,UE到RRU3的RSRP为2dbm,UE到RRU4的RSRP为7dbm,则确定UE的信号强度最大RRU为RRU4。
404:基于信号强度最大RRU对工作RRU集合进行筛选,生成UE的第一配对RRU集合。
在得到信号强度最大RRU之后,本实施例提供的方法,还将基于信号强度最大RRU对工作RRU集合进行筛选,进而生成第一配对RRU集合。
将基于信号强度最大RRU对工作RRU集合进行筛选,生成第一配对RRU集合,包括但不限于:将信号强度最大RRU从工作RRU集合中删除,并将工作RRU集合中的剩余的其余RRU,组成第一配对RRU集合。例如,设定任意一个UE的工作RRU集合中包含四个RRU,分别为:RRU1、RRU2、RRU3、RRU4,其中,RRU1为UE的信号强度最大RRU,将RRU1从UE的工作RRU集合中删除后,将工作RRU集合中剩余的其他RRU:RRU2、RRU3、RRU4,组成第一配对RRU集合。
405:获取第一配对RRU集合中每个RRU服务的UE,将第一配对RRU集合中每个RRU服务的UE组成配对UE集合。
由于本实施例提供的资源调度方法,在对当前待调度UE进行资源调度时,主要在配对UE集合中为当前待调度的UE找到可以配对的配对UE,之后通过更改当前待调度UE的初始用户属性,以实现对UE进行资源调度的同时,降低小区间的干扰,提高资源的利用效率。因此,在进行资源调度之前,本实施例提供的方法还需要确定出配对UE集合。
在确定配对UE集合时,可先获取第一配对RRU集合中每个RRU,然后获取每个RRU服务的UE,进而根据每个RRU提供服务的UE,生成配对UE集合,该配对UE集合中包含了每个RRU提供服务的UE。例如,第一配对RRU集合中包含RRU1、RRU2、RRU3,其中,RRU1提供服务的UE为UE1和UE2,RRU2提供服务的UE为UE3,RRU3提供服务的UE为UE1和UE4。根据每个RRU提供服务的UE,可得到配对UE集合,该配对UE集合中包含 UE1、UE2、UE3和UE4。
406:判断第一配对RRU集合中是否存在为UE提供服务的RRU,若存在,则执行步骤407。
在本实施例中,第一配对RRU集合中是否存在为UE提供服务的RRU,决定着在配对UE集合中能否找到与UE配对的配对UE,当第一配对RRU集合中存在为UE提供服务的RRU,说明在配对UE集合中可能找到与UE配对的配对UE,本发明实施例仅以此种情况为例进行说明,具体参见后续步骤407至409。而在本发明的另一个实施例中,当第一配对RRU集合中不存在为UE提供服务的RRU时,说明在配对UE集合中不能找到与UE配对的配对UE,此时可确定UE的实际用户属性为初始用户,进而根据UE的初始用户属性对UE进行资源调度。
407:根据第一配对RRU集合和配对UE集合,确定UE的第二配对RRU集合。
具体地,根据第一配对RRU集合和配对UE集合,确定UE的第二配对RRU集合的方式,包括但不限于如下步骤:
第一步,根据配对UE集合中各个UE的业务类型,确定各个UE的优先级。
其中,UE的业务类型为低优先级业务、高优先级业务等,本实施例不对UE的业务类型作具体的限定。在根据配对UE集合中各个UE的业务类型,确定各个UE的优先级时,首先,按照配对集合中各个UE的业务优先级由高到低的顺序,对配对UE集合中各个UE进行排序;然后,根据排序结果,确定各个UE的优先级。例如,配对UE集合中包含的UE为UE1、UE2和UE3,若UE1的业务类型为高优先级、UE2的业务类型为低优先级、UE3的业务类型为较高优先级,则按照配对UE集合中各个UE的业务优先级,对配对集合中各个UE进行排序,可得到排序结果为:UE1>UE3>UE2,进而根据排序结果,确定出配对UE集合中各个UE的优先级顺序为:UE1>UE3>UE2。
第二步,对配对UE集合中每个配对UE与UE进行相关性计算。
关于对配对UE集合中每个配对UE与UE进行相关性计算的方式,包括但不限于:采用正交性系数Orthval公式进行计算。
其中,正交性系数Orthval公式为:
ρ2=|(wu)H·wv|2
其中,ρ2为u用户与v用户之间的相关性,wu为u用户的权值向量,H为转秩符号,wv为v用户的权值向量。
第三步,依照优先级由高到低的顺序,依次判断各个配对UE与UE是否具有相关性。
当按照优先级由高到低的顺序,依次判断各个配对UE与UE是否具有相关性时,若配对UE与UE之间的相关性ρ2大于第二预设阈值,则判断配对UE与UE之间具有相关性;若配对UE与UE之间的相关性ρ2小于第二预设阈值则判断配对UE与UE之间不具有相关性。其中,第二预设阈值可以为1、2、3等,本实施例不对第二预设阈值作具体的限定。
第四步,如果优先级最高的配对UE与UE具有相关性,则获取优先级最高的配对UE的工作RRU,将优先级最高的配对UE的工作RRU从第一配对RRU集合中删除,得到第二配对RRU集合。
当优先级最高的配对UE与UE具有相关性,说明优先级最高的配对UE与UE能够配对成功,此时可获取优先级最高的配对UE的工作RRU,进而将优先级最高的配对UE的工作RRU从第一配对RRU集合中删除,并将第一配对RRU集合中的其余RRU,组成第二配对RUU集合。
需要说明的是,在将优先级最高的配对UE的工作RRU从第一配对RRU集合中删除时,仅将第一配对RRU集合中包含的RRU删除,对于第一配对RRU集合中不包含的RRU,无需作删除处理。
另外,如果优先级最高的配对UE与UE不具有相关性,此时可计算优先 级第二高的配对UE与UE是否具有相关性,若优先级第二高的配对UE与UE具有相关性,则获取优先级第二高的配对UE的工作RRU,将优先级第二高的配对UE的工作RRU从第一配对RRU中删除,并将第一配对RRU集合中的其余RRU组成第二配对RRU集合;若优先级第二高的配对UE与UE不具有相关性,则依次判断其余配对UE与UE是否具有相关性;若其余配对UE中存在与UE具有相关性的配对UE,则按照处理优先级最高的配对UE得到第二配对RRU集合的方式处理其余配对UE中与UE具有相关性的配对UE。在此过程中,若遍历了其余配对UE中所有的UE,均不存在与UE具有相关性的配对UE,则可确定UE的实际用户属性为初始用户属性。
408:根据第二配对RRU集合与UE的初始用户属性,确定UE的实际用户属性。
关于根据第二配对RRU集合与UE的初始用户属性,确定UE的实际用户属性的方式,包括但不限于如下两种情况:
第一种情况:如果第二配对RRU集合中不存在为UE提供服务的RRU,则根据UE的初始用户属性,确定UE的实际用户属性。
针对第一种情况,当第二配对RRU集合中不存在为UE提供服务的RRU,说明具有相关性的配对UE与UE配对成功,此时根据UE的初始用户属性,确定UE的实际用户属性。具体地,如果UE的初始用户属性为全部联合调度用户,则确定UE的实际用户属性为部分联合调度用户;如果UE的初始用户属性为部分联合调度用户,则确定UE的实际用户属性为独立调度用户。
在确定UE的实际用户属性之后,本实施例提供的方法,还将确定UE是否为BF用户,若UE为BF用户,则对UE的波束方向作加权处理。关于对UE的波束方向作加权处理的方式,包括但不限于:调整波束方向在每一维度上的系数,使UE调整后的波束零陷(Null Forming)朝向配对UE。
第二种情况:如果第二配对RRU集合中存在为UE提供服务的RRU,则确定新的第二配对集合,进而根据新的第二配对集合,确定UE的实际用户属 性。
针对第二种情况,当第二配对RRU集合中不存在为UE提供服务的RRU,说具有相关性的配对UE与UE配对不成功,此时可按照优先级由高到低的顺序,重新根据其余配对UE与第一配对RRU集合,确定一个新的第二配对RRU集合,直至新的第二配对RRU集合中不存在为UE提供服务的RRU,UE与具有相关性的配对UE能够配对成功。在此过程中,若遍历了其余配对UE中所有的UE,均不能确定出使UE能够配对成功的新的第二配对RRU集合,则将UE的初始用户属性作为UE的实际用户属性。
409:根据UE的实际用户属性,对UE进行资源调度。
在确定出UE的实际用户属性之后,基于UE的实际用户属性,对UE进行资源调度。当UE的实际用户属性为独立调度用户,此时为UE提供服务的RRU为一个,当UE需要资源时,该RRU可为UE调度及发送资源;当UE的实际用户属性为部分调度用户,此时为UE提供服务的RRU为逻辑小区内的部分RRU,当UE需要资源时,该部分RRU可为UE调度及发送资源等。
本发明实施例提供的方法,通过确定UE的信号强度最大RRU,基于信号强度最大RRU对工作RRU集合进行筛选,得到UE的第一配对RRU集合,之后基于第一配对RRU集合,生成配对UE集合,当第一配对RRU集合中存在为UE提供服务的RRU时,根据第一配对RRU集合和配对UE集合,确定UE的第二配对RRU集合,进而根据第二配对RRU集合和初始用户属性,确定UE的实际用户属性,从而根据UE的实际用户属性,对UE进行资源调度。由于UE的实际用户属性可以反映出UE与其他UE的干扰情况,因此,根据UE的实际用户属性对UE的资源进行调度,不仅降低了小区间的干扰,而且提高了资源利用效率。
上述图4所示的实施例在获取UE的工作RRU集合中,将能够为UE提供服务的所有RRU均作为工作RRU集合中的元素,而这些RRU中可能存在干 扰较强的RRU,导致进行资源调度时小区间干扰较大。为了降低小区间的干扰,本实施例在上述图4所示的实施例基础上提供了一种资源调度方法,参见图6,本实施例提供的方法流程包括:
601:获取UE的初始用户属性。
本步骤的具体实现方式与上述步骤401相同,具体参见上述步骤401,此处不再赘述。
602:根据UE的隔离度范围,确定为UE提供服务的各个RRU,获取由各个RRU组成的工作RRU集合。
其中,隔离度为无线直放站覆盖天线端口与施主天线之间信号的损耗。隔离度可分为垂直隔离度和水平隔离度。隔离度是直放站应用中的一个重要因素,可以反应出小区间的干扰。
为了降低小区间的干扰,提高系统资源利用效率,本实施例在获取UE的工作RRU集合时,还将根据UE的隔离度范围,确定为UE提供服务的各个RRU,并将为UE提供服务的各个RRU组成工作RRU集合,进而获取工作RRU集合。
关于根据UE的隔离度范围,确定为UE提供服务的各个RRU时,包括但不限于:根据隔离度计算公式进行确定。其中,隔离度计算公式为:
Figure PCTCN2015092750-appb-000001
其中,g为隔离度,N1为一个中间量,N1的取值为0,1,2,….,N-1,i1的取值为0,1,2,….,N-1,i2的取值为0,1,2,….,N-1,M为循环次数,M=N-1,N为RRU的数量,Di=RSRP[0]-RSRP[i],其中,i=i1或i2。具体计算过程,如下:
(1)、将UE到各个RRU的RSRP从大到小进行排序,并将排序后的RSRP值记为RSRP[i],将排序后的编号记为RSRP[i];
(2)、将RSRP[0]与RSRP[i]作差运算,得到Di;
(3)、将Di值代入到上述隔离度公式中,得到UE到一个RRU的隔离度;
(4)、逐步增大N1值,并重复执行上述(1)至(3)N次,得到N个隔离度。
(5)将得到的N个隔离度与第三预设阈值进行比较,将小于第三预设阈值的隔离度对应的RRU组成工作RRU集合。其中,第三预设阈值为0,1,2等,本实施例不对第三预设阈值作具体的限定。
603:根据UE到工作RRU集合中各个RRU的RSRP,确定UE的信号强度最大RRU。
本步骤的具体实现方式与上述步骤403相同,具体参见上述步骤403,此处不再赘述。
604:基于信号强度最大RRU对工作RRU集合进行筛选,生成UE的第一配对RRU集合。

本步骤的具体实现方式与上述步骤405相同,具体参见上述步骤405,此处不再赘述。
606:判断第一配对RRU集合中是否存在为UE提供服务的RRU。
本步骤的具体实现方式与上述步骤406相同,具体参见上述步骤406,此处不再赘述。
607:当第一配对RRU集合中存在为UE提供服务的RRU,根据第一配对RRU集合和配对UE集合,确定UE的第二配对RRU集合。
本步骤的具体实现方式与上述步骤407相同,具体参见上述步骤407,此处不再赘述。
608:根据第二配对RRU集合,确定UE的实际用户属性。

609:根据UE的实际用户属性,对UE进行资源调度。
本步骤的具体实现方式与上述步骤409相同,具体参见上述步骤409,此处不再赘述。
本发明实施例提供的方法,通过确定UE的信号强度最大RRU,基于信号强度最大RRU对工作RRU集合进行筛选,得到UE的第一配对RRU集合,之后基于第一配对RRU集合,生成配对UE集合,当第一配对RRU集合中存在为UE提供服务的RRU时,根据第一配对RRU集合和配对UE集合,确定UE的第二配对RRU集合,进而根据第二配对RRU集合和UE的初始用户属性,确定UE的实际用户属性,从而根据UE的实际用户属性,对UE进行资源调度。由于UE的实际用户属性可以反映出UE与其他UE的干扰情况,因此,根据UE的实际用户属性对UE的资源进行调度,不仅降低了小区间的干扰,而且提高了资源利用效率。
由于BF用户的波束方向仅朝向自身,对邻区的其他UE干扰较小,而上述图4所示的实施例在获取配对UE集合中,将第一配对RRU集合中各个RRU服务的UE均作为配对UE集合中的元素,而这些配对UE对当前调度的UE可能存在较强的干扰,因此,为了降低小区间的干扰,本实施例在上述图4所示的实施例基础上提供了一种资源调度方法,该资源调度方法在确定配对UE集合时,还将对图4所示的实施中获取到的第一配对RRU集合中各个RRU服务的UE进行筛选,并将筛选出的BF用户组成配对UE集合,参见7,本实施例提供的方法流程包括:
701:获取UE的初始用户属性。
本步骤的具体实现方式与上述步骤401相同,具体参见上述步骤401,此 处不再赘述。
702:基于UE的位置信息或干扰强度信息,确定为UE提供服务的各个RRU,获取由各个RRU组成的工作RRU集合。
本步骤的具体实现方式与上述步骤402相同,具体参见上述步骤402,此处不再赘述。

本步骤的具体实现方式与上述步骤403相同,具体参见上述步骤403,此处不再赘述。
704:基于信号强度最大RRU对工作RRU集合进行筛选,生成UE的第一配对RRU集合。
本步骤的具体实现方式与上述步骤404相同,具体参见上述步骤404,此处不再赘述。
705:获取第一配对RRU集合中每个RRU提供服务的UE,在每个RRU提供服务的UE中筛选BF用户,将每个RRU提供服务的UE中筛选出的BF用户组成配对UE集合。
由于上述步骤704中已经得到了第一配对RRU集合,因此,本步骤在上述步骤704的基础上,将获取第一配对RRU集合中每个RRU,并获取每个RRU服务的UE,进而在每个RRU提供服务的UE中筛选出BF用户,从而根据筛选出的BF用户,得到配对UE集合,该配对UE集合中包含每个RRU提供服务的BF用户。例如,第一配对RRU集合中包含RRU1、RRU2、RRU3,其中,RRU1提供服务的UE为UE1和UE2,RRU2提供服务的UE为UE3,RRU3提供服务的UE为UE1和UE4。若UE1和UE3为BF用户,则包含UE1和UE3的集合作为配对UE集合。
706:判断第一配对RRU集合中是否存在为UE提供服务的RRU。
本步骤的具体实现方式与上述步骤406相同,具体参见上述步骤406,此 处不再赘述。
707:当第一配对RRU集合中存在为UE提供服务的RRU,根据第一配对RRU集合和配对UE集合,确定UE的第二配对RRU集合。
本步骤的具体实现方式与上述步骤407相同,具体参见上述步骤407,此处不再赘述。
708:根据第二配对RRU集合,确定UE的实际用户属性。

本发明实施例提供的方法,通过确定UE的信号强度最大RRU,基于信号强度最大RRU对工作RRU集合进行筛选,得到UE的第一配对RRU集合,之后基于第一配对RRU集合,生成配对UE集合,当第一配对RRU集合中存在为UE提供服务的RRU时,根据第一配对RRU集合和配对UE集合,确定UE的第二配对RRU集合,进而根据第二配对RRU集合和初始用户属性,确定UE的实际用户属性,从而根据UE的实际用户属性,对UE进行资源调度。由于UE的实际用户属性可以反映出UE与其他UE的干扰情况,因此,根据UE的实际用户属性对UE的资源进行调度,不仅降低了小区间的干扰,而且提高了资源利用效率。
