Description

通信处理方法、BBU、RHUB和第二pRRU
本申请要求于2019年10月24日提交中国专利局,申请号为201911018505.X,发明名称为“通信处理方法、BBU、RHUB和第二pRRU”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术,尤其涉及一种通信处理方法、BBU、RHUB和第二pRRU。
背景技术
随着通信技术的发展,室内已成为移动业务的高发区。目前,室内信号覆盖主要通过室内分布系统来实现,通过各种室内天线将基站的信号均匀地分布到室内的每个角落。
目前,室内分布系统主要包括新型数字化室分系统(digital indoor system,DIS)和传统模拟室分系统(distributed antenna system,DAS)。而DIS系统如图1A所示,DIS系统分为三级架构,分别为基带处理单元(base band unit,BBU)、射频拉远单元集线器(remote radio unit hub,RHUB)和小型射频拉远单元(picro-remote radio unit,pRRU),一个BBU可以连接一个或多个RHUB(图1A仅示出连接一个RHUB的场景),一个RHUB可以连接多个pRRU。其工作原理是:BBU将下行信号发送给RHUB,RHUB与pRRU之间通过一根网线连接,RHUB将下行信号分发给各个pRRU,各个pRRU将下行信号处理为射频信号之后,通过射频馈线、合/分路器、天线等传输设备将射频信号接入室内。室内的终端将反馈信号发送给pRRU,各个pRRU再将反馈信号发送给RHUB,RHUB将各个反馈信号进行汇聚后,再传输给BBU。
但是,在该系统中,多个pRRU发射该终端设备的下行信号是相同的,由于pRRU安装在不同位置上,相同的下行信号经过不同的pRRU到达终端设备时,就会存在时延,而时延越大,信号的相干带宽越小,当终端设备占用的信号带宽大于该相干带宽时,则会出现频率选择性衰落,导致信号占用的频带内出现信号失真,影响下行信道传输质量,降低了下行传输性能。

具体实施方式
本申请实施例提供了一种通信处理方法、BBU、RHUB和第二pRRU,用于降低信号的频率选择性衰落的概率,提升下行传输性能。
请参阅图1A,图1A为本申请实施例DIS系统的一个架构示意图,该DIS系统分为三级架构,分别为BBU、RHUB和pRRU,一个BBU可以连接一个或多个RHUB(图1A仅示出连接一个RHUB的场景),一个RHUB可以连接多个pRRU。下面通过图1B说明其工作原理,如图1B所示,BBU将下行信号发送给RHUB,RHUB与pRRU之间通过一根网线连接,RHUB将下行信号分发给各个pRRU,各个pRRU将下行信号处理为射频信号之后,通过射频馈线、合/分路器、天线等传输设备将射频信号接入室内。室内的终端将反馈信号发送给pRRU,各个pRRU再将反馈信号发送给RHUB,RHUB将各个反馈信号进行汇聚后,再传输给BBU。
但是,在该系统中,多个pRRU发射的下行信号是相同的,由于pRRU安装在不同位置上,相同的下行信号经过不同的pRRU到达终端设备时,就会存在时延,而时延越大,信号的相干带宽越小,当终端设备占用的信号带宽大于该相干带宽时,则会出现频率选择性衰落,导致信号占用的频带内出现信号失真,影响下行信道传输质量,降低了下行传输性能。
有鉴于此,本申请实施例提供一种通信处理方法,用于降低信号的频率选择性衰落的概率,提升下行传输性能。BBU接收第一终端设备发送的上行测量信号,并根据该上行测量信号生成空口测量报告,该空口测量报告包括第一终端设备与该第一终端设备所在的小区中的至少一个pRRU之间的空口信道质量值;然后BBU根据该空口测量报告从该至少一个pRRU中选择目标pRRU,该目标pRRU用于向第一终端设备发送下行信号,且该目标pRRU的数量小于该至少一个pRRU的数量。因此,本申请实施例的技术方案,BBU根据该空口测量报告从该至少一个pRRU中选择目标pRRU来向第一终端设备发送下行信号,相比于现有技术,减少发送该第一终端设备的下行信号的路径,从而减少传输时延,降低了信号的频率选择性衰落的概率,提升下行传输性能。
需要说明的是,本申请实施例中,BBU可以是接入网设备中的基带处理单元,而接入设备可以包括:演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(baseband unit,BBU),无线保真(wireless fidelity,WIFI)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission and reception point,TRP或者transmission point,TP)等,还可以为5G,如,NR,系统中的gNB,或,传输点(TRP或TP),5G系统中的基站的一个或一组(包括多个天线面板)天线面板,或者,还可以为构成gNB或传输点的网络节点,如基带单元(BBU),或,分布式单元(DU,distributed unit)等。
在一些部署中,gNB可以包括集中式单元(centralized unit,CU)和DU。gNB还可以包括射频单元(radio unit,RU)。CU实现gNB的部分功能,DU实现gNB的部分功能,比如,CU实现无线资源控制(radio resource control,RRC),分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能,DU实现无线链路控制(radio link control, RLC)、媒体接入控制(media access control,MAC)和物理(physical,PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息,或者,由PHY层的信息转变而来,因而,在这种架构下,高层信令,如RRC层信令或PHCP层信令,也可以认为是由DU发送的,或者,由DU+RU发送的。可以理解的是,网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外,CU可以划分为接入网RAN中的网络设备,也可以将CU划分为核心网CN中的网络设备,在此不做限制。有线通信系统中的接入网设备可以包括:无源光网络PON(Passive Optical Network),高速数字用户线HDSL(High Speed Digital Subscriber Line),不对称数字用户线ADSL(Asymmetrical Digital Subscriber Line)以及具有V5接口(V5interface)的综合数字用户环路等等。
本申请实施例中,RHUB可以为交换机,或者为路由器等设备;而pRRU可以为天线设备等。终端设备又称之为用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等,终端设备是一种具有无线收发功能的设备,是移动用户与网络交互的入口,能够提供基本的计算能力,和存储能力,并向用户显示业务窗口、接收用户的输入操作。在5G通信系统中,终端会采用新空口技术与RAN设备建立信号连接和数据连接,从而传输控制信号和业务数据到网络。终端设备可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。例如,该终端设备可以包括移动电话(或称为“蜂窝”电话),具有移动终端的计算机,便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,智能穿戴式设备等。例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备。
本申请实施例中,BBU根据空口测量报告从该至少一个pRRU中选择目标pRRU,以用于向第一终端设备发送第一终端设备的下行信号,而具体的实现方式可以有多种,下面通过举例说明:
方式一:BBU确定目标pRRU之后,BBU向RHUB发送第一指示信息,该第一指示信息用于指示该RHUB在第一时长内不向第二pRRU发送该第一终端设备的下行信号,该第二pRRU为该第一终端设备所在的小区中包括的pRRU中除去目标pRRU的pRRU,具体该方式通过图2A所示的实施例进行说明。
方式二:BBU确定目标pRRU之后,BBU向第二pRRU发送第二指示信息,该第二指示信息用于指示该第二pRRU在第一时长内不向第一终端设备发送该第一终端设备的下行信号,该第二pRRU为该第一终端设备所在的小区中包括的pRRU中除去目标pRRU的pRRU,具体该方式通过图3A所示的实施例进行说明。
请参阅图2A,图2A为本申请实施例通信处理方法的一个实施例示意图,该方法包括:
201、该至少一个pRRU接收第一终端设备发送的上行测量信号。
结合图1B所示,第一终端设备可以根据BBU所指示的发送功率发送该上行测量信号,那么在该第一终端设备所在的小区中距离该第一终端设备较近的至少一个pRRU可以接收该上行测量信号,即该第一终端设备所在的小区中能够接收到该上行测量信号的pRRU属于 该至少一个pRRU。
其中,该第一终端设备发送的上行测量信号为模拟电信号。需要说明的是,该第一终端设备所在的小区指的是物理小区,例如,基带处理资源,该物理小区所占用的20M空口带宽。该物理小区中可以包括多个pRRU,且该多个pRRU通过一个或多个RHUB与BBU连接。
202、该至少一个pRRU向RHUB发送该上行测量信号。
其中,由于该第一终端设备发送的上行测量信号的形式为模拟电信号形式,所以该至少一个pRRU可以将该模拟电信号转换为数字电信号,并向该RHUB该数字电信号。
203、该RHUB向BBU发送该上行测量信号。
RHUB接收到该数字电信号之后,可以向BBU转发该数字电信号。
204、BBU根据该上行测量信号生成空口测量报告。
其中,该空口测量报告包括该第一终端设备与该第一终端设备所在的小区中的至少一个pRRU之间的空口信道质量值。
具体的,BBU可以根据该上行测量信号的功率确定确定该第一终端设备与该第一终端设备所在的小区中的至少一个pRRU之间的空口信道质量值,其中,该空口信道质量值可以为信噪比。
205、BBU根据该空口测量报告从该至少一个pRRU中选择目标pRRU。
其中,目标pRRU用于向第一终端设备发送第一终端设备的下行信号,该目标pRRU的数量小于该至少一个pRRU的数量。
BBU可以根据该空口测量报告携带的第一终端设备与该至少一个pRRU之间的空口信道质量值选择该目标pRRU,具体的实现过程请参阅图2B,图2B为本申请实施例的另一个实施例示意图,该方法包括:
205a:BBU判断该第一终端设备与该第一pRRU之间的空口信道质量值是否大于预设阈值,若是,则执行步骤205b;若否,则执行步骤205c。
205b:BBU将第一pRRU作为目标pRRU。
205c:BBU判断该第一pRRU是否用于向第二终端设备发送第二终端设备的下行信号,若是,则执行步骤205d;若否,则执行步骤205e。
当前该第一终端设备与该第一pRRU之间的空口信道质量值不大于该预设阈值时,那么BBU判断该第一pRRU是否被选择用于向第二终端设备发送第二终端设备的下行信号,如果是,则执行步骤205d;如果不是,则执行步骤205e;其中,第二终端设备为该小区内的任一终端设备,而该第二终端设备可能在位置距离该第一pRRU较近,即第二终端设备与第一pRRU之间的空口信道质量较好,那么BBU可以选择该第一pRRU向第二终端设备发送该第二终端设备的下行信号。
205d:将第一pRRU作为目标pRRU。
如果该第一pRRU用于向第二终端设备发送该第二终端设备的下行信号,则将第一pRRU作为目标pRRU。
205e:排除第一pRRU。
如果不是,那么排除第一pRRU,即在这种情况下,目标pRRU不包括该第一pRRU。
206、BBU向RHUB发送第一指示信息。
其中,第一指示信息用于指示RHUB在第一时长内不向第二pRRU发送第一终端设备的下行信号,该第二pRRU为该第二pRRU为该第一终端设备所在的小区中包括的pRRU中除去目标pRRU的pRRU。
在该可能的实现方式中,即意味着指示RHUB在第一时长内向目标pRRU发送该第一终端设备的下行信号。其中,也可以通过第一指示信息携带对应的指示字段指示RHUB在第一时长内向目标pRRU发送该第一终端设备的下行信号。其中,第一时长可以根据第一终端设备的移动情况(通过第一终端设备发送的空口测量报告来获知)来设定。其次,本申请实施例中,可以是在间隔时长内实施本申请实施例的方案,实际可以视第一终端设备的移动情况来设定该间隔时长。
例如,如图2C所示,第二pRRU包括pRRU0、pRRU2和pRRU3。例如,BBU指示RHUB在10ms内不向pRRU0、pRRU2和pRRU3发送该第一终端设备的下行信号,而BBU在第一时长内在pRRU1、pRRU4、pRRU5至pRRUn上向第一终端设备发送第一终端设备的下行信号,具体可以结合图2C所示,RHUB与pRRU之间带有交叉符的通信链路上不发送信号。可选的,BBU也可以按照10ms为时间周期,将接下来n个10ms对应的操作发送给RHUB,下面结合表1进行说明:
表1
Figure PCTCN2020123059-appb-000001
例如,如表1所示,BBU根据第一终端设备的空口测量报告确定了表1所示的各时间段内,对每个pRRU的使用需求,其中,“0”表示对应的pRRU选发关闭,“1”表示对应的pRRU选发开启。而具体该表1所示的时长可以结合实际来确定,例如,用户移动较为缓慢时,那么用户可能在短时间内可以通过同样的pRRU向该第一终端设备发送第一终端设备的下行信号。
本申请实施例中,BBU接收第一终端设备发送的上行测量信号,然后,BBU根据该上行测量信号生成空口测量报告,该空口测量报告包括第一终端设备与该第一终端设备所在的小区中的至少一个pRRU之间的空口信道质量值;然后BBU根据该空口测量报告从该至少一个pRRU中选择目标pRRU,该目标pRRU用于向第一终端设备发送下行信号,且该目标pRRU的数量小于该至少一个pRRU的数量,BBU向第二pRRU发送第一指示信息,第一指示信息用于指示RHUB在第一时长内不向第二pRRU发送第一终端设备的下行信号,该第二pRRU为该第二pRRU为该第一终端设备所在的小区中包括的pRRU中除去目标pRRU的pRRU,即意味着指示RHUB在第一时长内向目标pRRU发送该第一终端设备的下行信号。因此,本申请 实施例的技术方案,BBU根据该空口测量报告从该至少一个pRRU中选择目标pRRU来向第一终端设备发送下行信号,相比于现有技术,减少发送该第一终端设备的下行信号的路径,从而减少传输时延,降低了信号的频率选择性衰落的概率,提升下行传输性能。
请参阅图3A,图3A为本申请实施例通信处理方法的另一个实施例示意图,该方法包括:
301、该至少一个pRRU接收第一终端设备发送的上行测量信号。
302、该至少一个pRRU向RHUB发送该上行测量信号。
303、该RHUB向BBU发送该上行测量信号。
304、BBU根据该上行测量信号生成空口测量报告。
305、BBU根据空口测量报告从该至少一个pRRU中选择目标pRRU。
步骤301至步骤305与前述图2A所示的实施例中步骤201至步骤205类似,详细请参阅前述图2A所示的实施例中步骤201至步骤205的相关说明,这里不再赘述。
306、BBU向第二pRRU发送第二指示信息。
其中,第二指示信息用于指示第二pRRU在第一时长内不向第一终端设备发送该第一终端设备的下行信号,该第二pRRU为该第一终端设备所在的小区中包括的pRRU中除去目标pRRU的pRRU。其中,第一时长可以根据第一终端设备的移动情况(通过第一终端设备发送的空口测量报告来获知)来设定。其次,本申请实施例中,可以是在间隔时长内实施本申请实施例的方案,实际可以视第一终端设备的移动情况来设定该间隔时长。
下面结合表2进行说明,表2为pRRU0收到的20ms内的信号处理指示,具体如下:
表2
Figure PCTCN2020123059-appb-000002
由表2可知,pRRU0在20ms内不向第一终端设备发送第一终端设备的下行信号,其中,每个TTI可以为1ms。
而pRRU2和pRRU3也类似,同样收到表2所示的指示,在该20ms内不发送该第一终端设备的下行信号。具体可以结合图3B所示,pRRU与第一终端设备之间带有交叉符的通信链路上不发送信号。
307、BBU向目标pRRU发送第三指示信息。
其中,该第三指示信息用于指示目标pRRU在第一时长内向第一终端设备发送该第一终端设备的下行信号。
需要说明的是,步骤307是可选的,目标pRRU也可以是当未收到BBU发送的指示信息时,则默认在该第一时长内需要发送该第一终端设备的下行信号。也可以是目标pRRU根据该BBU的指示信息来确定在第一时长内发送该第一终端设备的下行信号,具体可以根据实际的情况来设定对应的处理逻辑,本申请不做限定。例如,BBU可以向pRRU1发送表3,表 3具体如下:
表3
Figure PCTCN2020123059-appb-000003
由表3可知,pRRU1在20ms内向第一终端设备发送第一终端设备的下行信号。
下面结合图3C具体示例说明通过本申请实施例的方法,第一终端设备在三个pRRU的射频合路下进行下行接口时,第一终端设备的下行峰值速率达到1.08Gbps~1.18Gbps,闭塞pRRU0和pRRU2后,相同环境下,第一终端设备峰值速率可以达到1.48Gbps~1.56Gbps,下行性能提升30%以上。
本申请实施例中,BBU接收第一终端设备发送的上行测量信号,然后,BBU根据该上行测量信号生成空口测量报告,该空口测量报告包括第一终端设备与该第一终端设备所在的小区中的至少一个pRRU之间的空口信道质量值;然后BBU根据该空口测量报告从该至少一个pRRU中选择目标pRRU,该目标pRRU用于向第一终端设备发送下行信号,且该目标pRRU的数量小于该至少一个pRRU的数量,BBU向第二pRRU发送第二指示信息,第二指示信息用于指示第二pRRU在第一时长内不向第一终端设备发送该第一终端设备的下行信号,该第二pRRU为该第一终端设备所在的小区中包括的pRRU中除去目标pRRU的pRRU。因此,本申请实施例的技术方案,BBU根据该空口测量报告从该至少一个pRRU中选择目标pRRU来向第一终端设备发送下行信号,相比于现有技术,减少发送该第一终端设备的下行信号的路径,从而减少传输时延,降低了信号的频率选择性衰落的概率,提升下行传输性能。
下面针对DAS系统存在的类似问题进行说明,请参阅图4,图4为DAS系统的一个架构示意图,DAS系统施主信源可以为宏基站、微蜂窝、分布式基站或中继接入的各类直放站等,输出到DAS信号分布系统的一般是模拟射频信号,通过DAS无源或有源器件进行信号分路传输,经馈线将信号尽可能平均分配至分散安装在各个区域的每一付天线上,从而实现室内信号的均匀分布。因此,DAS系统也同样存在类似的技术问题,那么可以在电缆/光纤传输线路与有源/无源天线之间增加对下行信号通路的控制模块,然后再由施主信源(例如,基站、微蜂窝等)通过本申请实施例的方法对该控制模块进行控制,从而实现在DAS系统下减少发送该第一终端设备的下行信号的路径,从而减少传输时延,降低了信号的频率选择性衰落的概率,提升下行传输性能。
需要说明的是,上述的方法实施例仅以选择目标pRRU来发送该第一终端设备的下行信号实现在DIS系统或DAS系统下减少发送该第一终端设备的下行信号的路径,从而下行传输性能,而在实际应用中,也可以通过降低或增加第一终端设备与pRRU之间的下行发送功率来实现,与上述方法实施例通过开启pRRU或关闭pRRU的方式属于类似的思路,即通过调控第一终端设备与pRRU之间的下行发送功率的方案同样属于本申请实施例所保护的范围。
下面对本申请实施例中提供的一种接入网设备进行描述。请参阅图5,本申请实施例中接入网设备的一个实施例,该接入网设备包括BBU,该BBU可以用于执行上述所示方法实施例中BBU执行的步骤,可以参考上述方法实施例中的相关描述。
