Description

一种波束调整的方法、用户设备和基站 技术领域
本发明涉及通信领域,尤其涉及一种波束调整的方法、用户设备和基站。
背景技术
为了进一步提升系统容量及频谱效率,下一代高频系统将进一步向着密集化的网络结构、更宽的带宽和更高的空间复用维度扩展的方向演进。毫米波频段拥有丰富的频谱资源,但其空间损耗大,大规模天线的使用是实现系统容量及频谱效率提升的最直接的有效手段。对于大规模天线系统,天线规模越大,波束越窄,因此,基站为了保证用户的覆盖,需要同时发射多个波束来覆盖整个扇区,其中,如图1所示,基站的天线单元分为N个天线子阵,一个天线子阵生成一个波束,共N个波束。如图2所示,基站的天线子阵生成N个波束,该基站的扇区覆盖范围内有多个UE(User Equipment,用户设备),每一个UE由基站的一个或者多个波束覆盖。
理想的情况,希望基站的波束可以覆盖整个扇区,并且波束之间的是没有交叠的。这样,属于不同波束覆盖范围内的UE可以通过空分的方式分配资源,而同一波束内覆盖的多个UE可以通过频分/时分的方式分配资源。然而,在实际的系统中,由于波束的增益不是突变的,要保证扇区的覆盖,波束之间肯定会有交叠的部分,这样对于处于多个波束交叠部分的UE,该UE可能会产生波束间干扰的问题,如图3所示,UE4、UE5和UE6同时收到波束i和波束k发送的信号,此时,若接收到各个波束的信号强度都比较强,各个波束的信号之间互为干扰,不可区分,如果为了避免干扰不对UE4、UE5和UE6分配资源,会影响用户体验,其中,现有技术为了规避各个波束之间的干扰,基站通过时分调度波束i和波束k的方式为UE4至UE6分配资源,这样,基站在调度波束i时,波束k处于闲置状态,不能同时获取两个波束的空间分集增益,导致系统容量下降。另外,对于有的天线子 阵,对应的信道质量较差,其生成的波束的覆盖范围内的UE接收到的信噪比SNR不能满足信号传输的要求,此时,该天线子阵无法用来为其覆盖的UE服务,造成资源的浪费。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例提供一种波束调整的方法,如图4所示,该方法包括:
S401、基站通过多个波束发送波束信息。
其中,该波束信息包括对应波束的波束标识和信道检测信息,以便用户设备根据该信道检测信息对覆盖该用户设备的波束进行检测,得到检测反馈信息。
可选地,在现有的高频无线通信系统中,基站可以通过高频段和/或低频段向该用户设备发送该波束信息。
具体地,处于该基站发出的波束的覆盖范围内的任一用户设备在获取到所述信道检测信息后,对覆盖该用户设备的波束进行检测,例如,覆盖该用户设备的波束为M个,M为大于或等于1的正整数,则该用户设备将该M个波束中符合条件的m个波束的标识通过检测反馈信息发送至该基站,其中,符合条件的m个波束的标识包括满足该用户设备的信号传输条件的波束的标识,和/或,信噪比SNR之差处于预设范围内的至少两个波束,和/或,SNR(Signal to Noise Ratio,信噪比)小于信号传输门限SNRthd的波束的标识。
S402、该基站接收至少一个用户设备发送的检测反馈信息。
其中,每一个用户设备发送的检测反馈信息中携带覆盖该用户设备且符合条件的波束的标识。
S403、该基站获取该检测反馈信息携带的Z个波束的标识,在该Z个波束中确定需要进行调整的Z1个波束。
其中,Z为大于或等于1的正整数,Z1为小于或等于Z的正整数。
具体地,基站从每一个用户设备发送的检测反馈信息中获取波束标识,例如,两个用户设备向基站发送检测反馈信息,其中,第一用户设备发送的检测反馈信息中包括m1个波束标识,第二用户设备发送的检测反馈信息中包括m2个波束标识,此时,若该m1个波束标识与该m2个波束标识中无相同的波束标识,则该基站从该第一用户设备和该第二用户设备发送的检测反馈信息中可获取到Z=m1+m2个波束;若该m1个波束标识与该m2个波束标识中包含相同的波束标识,则该基站从该第一用户设备和该第二用户设备发送的检测反馈信息中可获取到Z<m1+m2个波束。
进一步地,该基站在该Z个波束中确定需要进行调整的Z1个波束包括以下三种方式:
方式一、该Z个波束包括满足该用户设备的信号传输条件的波 束,该检测反馈信息包括该Z个波束的信道质量信息,该基站根据该Z个波束的标识和该Z个波束的信道质量信息在该Z个波束中确定需要进行重复覆盖问题调整的Z1个波束。
其中,该用户设备能接收到的多个满足所述用户设备的信号传输条件的波束之间存在重复覆盖问题。如图3所示,波束i和波束K均满足用户设备的信号传输条件,由于波束i和波束k同时覆盖UE4、UE5和UE6,这样,UE4至UE6向基站发送的检测反馈信息中均同时包括波束i和波束k的标识。此时,该基站根据该所有用户设备反馈的波束标识以及各波束的信道质量信息进行联合统计分析,确定波束i和波束k存在重复覆盖的问题,需要进行波束调整。
方式二、该Z个波束包括信噪比SNR之差处于预设范围内的至少两个波束,该检测反馈信息包括该Z个波束的信道质量信息,则该基站根据该Z个波束的标识和该Z个波束的信道质量信息在该Z个波束中确定需要进行波束间干扰问题调整的Z1个波束,其中,该用户设备能够接收到的信噪比SNR之差处于预设范围内的至少两个波束之间存在波束间干扰问题。
在本发明实施例一种可选地的实现方式中,所述存在波束间干扰问题的多个波束均不满足用户设备的信号传输条件的波束,此时,由于该多个波束均不能为用户设备服务,该基站可以不对该多个波束进行调整,本发明对此不做限定。
在本发明实施例另一种可选地的实现方式中,所述存在波束间干扰问题的多个波束中包括不满足用户设备的信号传输条件的波束,也包括满足用户设备的信号传输条件的波束,或者所述存在波束间干扰问题的多个波束均满足用户设备的信号传输条件的波束。
如图3所示,波束i满足用户设备的信号传输条件,波束K不满足用户设备的信号传输条件,但是对该波束i造成干扰,例如,该波束i的SNR大于该SNRthd,该波束k的SNR小于该SNRthd,且该波束i与该波束k之间的SNR之差在一定的干扰范围之内,这样,UE4至UE6向基站发送的检测反馈信息中均同时包括波束i和波束k 的标识。此时,该基站根据该所有用户设备反馈的波束标识以及各波束的信道质量信息进行联合统计分析,确定波束i和波束k存在波束间干扰的问题,需要进行波束调整。
方式三、该Z个波束包括信噪比SNR小于信号传输门限SNRthd的波束,该检测反馈信息包括该Z个波束的信道质量信息,则该基站根据该Z个波束的标识和该Z个波束的信道质量信息在该Z个波束中确定需要进行信道质量调整的Z1个波束。
具体地,任一用户设备在检测到覆盖该设备的第一波束的SNR小于该信号传输门限SNRthd时,该用户设备将该第一波束的标识反馈至该基站,则该基站确定该第一波束对应的第一天线子阵的相邻天线子阵,若该相邻天线子阵对应的波束的信噪比SNR大于该信号传输门限SNRthd,则确定该第一波束与该相邻天线子阵对应的波束为需要进行信道质量调整的Z1个波束。
这样,当用户设备不存在满足其信号传输条件的波束时,可以将覆盖该用户设备的波束中SNR最大的波束标识反馈至基站,此时,该SNR最大的波束即为上述第一波束。
需要说明的是,上述三种方式是基站根据用户设备不同的反馈方式进行的三种确定需要调整的Z1个波束的方式,在具体实施中,用户设备可以在检测反馈信息中携带重复覆盖波束的标识、存在波束间干扰的波束的标识、SNR小于信号传输门限SNRthd的波束的标识中的至少一种,这样,根据至少一个用户设备的反馈由该基站按照上述三种方式中的至少一种进行分析确定波束分布存在的问题,其中,该基站在分析波束分布存在的问题时,可以根据局部区域的总容量为准则和/或以用户体验为准则。
另外,该基站还可以同时在该Z个波束中确定其他需要进行调整的Z2个波束,其中,该Z2个波束与该Z1个波束之间无相同的波束,该Z2个波束与该Z1个波束可以存在不同的波束分布问题,例如,该Z1个波束为相邻的波束1,波束2和波束3,其中波束1对应的SNR小于SNRthd,需要进行信道质量的调整,该Z2个波束为波 束4和波束5,该波束4和波束5重复覆盖相同的用户设备,需要进行重复覆盖问题的调整。
S404、该基站对该Z1个波束对应的Z1个天线子阵进行至少一次调整。
示例地,预先设置该基站发出的每个波束的波束标识,并在该基站中存储每个波束的波束标识与生成该波束的天线子阵的对应关系,则该基站在确定需要进行调整的Z1个波束后,根据该Z1个波束的标识确定生成该Z1个波束的天线子阵。
进一步地,针对上述方式一和方式二,在本发明实施例的一种可能的实现方式中,若生成该Z1个波束的Z1个天线子阵相邻,该基站将该Z个天线子阵合并为一个联合天线子阵,通过该联合天线子阵生成的一个联合波束覆盖用户设备。
示例地,该至少一个用户设备向基站发送的反馈检测信息中包括波束i和波束k,该基站确定该波束i和波束k之间存在重复覆盖的问题或者波束间干扰的问题,则该基站根据该波束i和波束k的标识确定生成该波束i和波束k的天线子阵i和天线子阵k,如图5所示,天线子阵i和天线子阵k相邻,则该基站将该天线子阵i的阵列单元和该天线子阵k的阵列单元合并组成一个新的联合子阵,并由该联合子阵生成的波束覆盖用户设备,如图6所示,此时,原本由波束i和波束k同时覆盖的用户设备UE4、UE5和UE6,均变为由一个联合波束覆盖,这样,避免了重复覆盖问题和波束间的干扰,保证了UE4、UE5和UE6的用户体验。
上述只是举例说明,在实际应用中,一个用户设备可能被两个以上波束覆盖,此时,该用户设备向该基站反馈的波束标识包括两个以上的波束标识,该基站可以将两个以上相邻的天线子阵合并为一个天线子阵,本发明对此不做限定。
在本发明实施例的另一种可能的实现方式中,该基站对该Z1个天线子阵的阵列单元进行重新分配组成波束宽互不相同的U个天线子阵,U为大于或等于2的正整数。
示例地,该至少一个用户设备向基站发送的反馈检测信息中包括波束i和波束k,该基站确定该波束i和波束k之间存在重复覆盖的问题或者波束间干扰的问题,则该基站根据该波束i和波束k的标识确定生成该波束i和波束k的天线子阵i和天线子阵k,如图7所示,天线子阵i和天线子阵k相邻,则该基站将该天线子阵i的阵列单元和该天线子阵k的阵列单元进行重新分配,为该天线子阵i分配较少的阵列单元形成新的天线子阵a,为该天线子阵k分配较多的阵列单元形成新的天线子阵b,并由该天线子阵a和该天线子阵b生成的波束a和波束b覆盖用户设备,如图8所示,此时,原本波束i覆盖用户设备UE1至UE6,波束k覆盖用户设备UE4至UE8,变为由波束a覆盖用户设备UE1至UE6,波束b覆盖用户设备UE7和UE8,这样,原本由波束i和波束k同时覆盖的用户设备UE4、UE5和UE6,均变为由波束a覆盖,避免了重复覆盖问题和波束间干扰问题,保证了UE4、UE5和UE6的用户体验。
上述只是举例说明,基站将两个等波束宽的波束调整为一个宽波束和一个窄波束,本发明实施例对调整后新生成的波束数量不做限定,例如,该基站可以将两个波束对应的天线子阵重新分配为三个天线子阵。
在本发明实施例的另一种可能的实现方式中,若生成该Z1个波束的Z1个天线子阵不相邻,则该基站调整该Z1个不相邻的天线子阵的波束成型算法,改变该Z1个天线子阵生成的波束的波束宽度和/或波束指向。
示例地,该至少一个用户设备向基站发送的反馈检测信息中包括波束i和波束k,该基站确定该波束i和波束k之间存在重复覆盖的问题或者波束间干扰的问题,则该基站根据该波束i和波束k的标识确定生成该波束i和波束k的天线子阵i和天线子阵k,如图9所示,天线子阵i和天线子阵k不相邻,此时,该基站可以通过波束成型算法分别来调整波束i和波束k的波束指向和/或波束宽度。如图8所示,该波束a为该天线子阵i调整波束成型算法后生 成的波束,该波束b为该天线子阵k调整波束成型算法后生成的波束。
可选地,针对上述方式三,该基站对该Z1个天线子阵的阵列单元进行重新分配,增加SNR小于该SNRthd的第一天线子阵的阵列单元的数量,使得该第一天线子阵生成的第一波束的SNR大于该SNRthd,并且与调整后的该第一天线子阵相邻的天线子阵对应的波束的SNR仍然大于该SNRthd
值得说明的是,对于不同天线子阵生成的波束,由于经过的信道衰落和路径损耗不同,其对应的信道质量存在差别。对于信道质量较好的信道对应的天线子阵,该天线子阵生成的波束覆盖范围内的用户设备接收到的信噪比满足信号传输的需求,例如,该用户设备接收到的SNR大于信号传输门限SNRthd;而对于信道质量较差的信道对应的天线子阵,该天线子阵生成的波束覆盖范围内的用户设备接收到的信噪比不满足信号传输的需求,例如,该用户设备接收到的信噪比SNR小于信号传输门限SNRthd,此时,该天线子阵无法用来为其覆盖的用户设备服务,造成资源的浪费。
而在本发明实施例中,用户设备根据该信道检测信息在检测覆盖该用户设备的波束的波束标识时,可以同时检测各波束对应的信道质量,并将携带各波束的波束标识和各波束对应的信道质量信息的检测反馈信息发送至基站,这样,该基站即可根据该波束标识获知覆盖该用户设备的波束对应的天线子阵,根据该信道质量信息即可获知该天线子阵对应的信道质量,这样,对于不存在满足其信号传输条件的波束的用户设备,该基站可以增强覆盖该用户设备的波束中SNR最大的波束的信道质量,使其满足信号传输条件,为该用户设备提供服务,避免了资源浪费。
以图10举例说明,若覆盖用户设备的天线子阵i、天线子阵j和天线子阵k相邻,且该基站由该信道质量信息确定该天线子阵i的对应的SNR为A1,该天线子阵j的对应的SNR为A2,该天线子阵k的对应的SNR为A3,且A1>=A2>=SNRthd>A3,由于该天线子阵k对 应的信噪比SNR小于信号传输门限SNRthd,因此该天线子阵k无法用来为其覆盖的用户设备服务。此时,该基站将该天线子阵i、天线子阵j和天线子阵k的阵列单元进行重新分配,将更多的阵列单元分配给该天线子阵k,将较少的阵列单元分配给该天线子阵i和该天线子阵j,由此形成新的三个天线子阵i′、j′和k′,并由该天线子阵i′、j′和k′生成的波束覆盖该用户设备。
需要说明的是,该基站在一次调整后,可以继续指示该用户设备进行波束检测,并接收该用户设备发送新的三个天线子阵i′、j′和k′对应的信道质量,如图10中所示的A1′、A2′和A3′,则该基站判断该A1′、A2′和A3′是否均大于或等于信号传输门限SNRthd,若是,则停止调整,若否,则该基站继续对该天线子阵i′、j′和k′的阵列单元进行重新分配,直到新生成的天线子阵对应的SNR均大于或等于该信号传输门限SNRthd
另外,在本发明实施例一种可能的实现方式中,基站可预设调整次数门限,并在进行波束调整过程中对调整次数进行计数,当调整次数达到该调整次数门限时,若仍然存在调整后的波束的SNR小于信号传输门限SNRthd,则该基站根据最后一次的调整结果,进行资源分配。
具体地,该基站在每次调整波束的分布后,通过调整后的波束发送波束信息继续指示用户设备进行波束检测,通过循环多次的调整,直到该基站根据该用户设备反馈的检测信息确定该Z个波束中不存在需要进行调整的波束,或者该基站的调整次数达到预设的调整次数门限,此时,该基站停止对波束的调整,并向所有该基站的波束覆盖范围内的用户设备发送波束确认信息,以便用户设备接收到该波束确认信息后,停止波束检测和信息反馈,这样,基站和用户设备相互确认完成,可以进行后续的资源分配和数据通信过程。
采用上述方法,基站通过至少一个用户设备发送的检测反馈信息,确定需要进行调整的波束,并对生成该波束的天线子阵进行调整,使得调整后的天线子阵生成的波束重复覆盖减少、波束间干扰 减小,或者使得更多的波束满足信号传输门限,提高系统的容量,提升了用户体验。
本发明实施例提供一种波束调整的方法,如图11所示,该方法包括:
S1101、用户设备接收基站通过波束发送的波束信息。
其中,该波束信息包括对应波束的波束标识和信道检测信息。
值的说明的是,较优的,各波束的信道检测信息属于不相关信号。
S1102、该用户设备根据该信道检测信息对覆盖该用户设备的M个波束进行检测,得到检测反馈信息。
其中,该检测反馈信息包括m个波束的标识,m为大于或等于1,并且小于或等于M的正整数。
可选地,该用户设备在M个波束中检测出满足该用户设备的信号传输条件的波束,例如,该用户设备检测覆盖该用户设备的第一波束的信道质量,若该第一波束的信道质量满足信号传输的条件,则从该第一波束对应的波束信息中获取该第一波束的波束标识,该第一波束为覆盖该用户设备的任一波束,直到该用户设备将覆盖该用户设备的所有波束都检测完毕,将满足该用户设备的信号传输条件的波束的波束标识和各波束的信道质量信息通过检测反馈信息发送至基站。
可选地,该用户设备在该M个波束中检测出信噪比SNR之差处于预设范围内的至少两个波束,例如,存在2个波束覆盖该用户设备,则该用户设备可以通过判断波束1和波束2之间的SNR之差是否在预设的差值范围内,确定该该波束1和该波束2是否存在波束间干扰,若该波束1和波束2之间的SNR相近,则该波束1和波束2之间存在波束间干扰问题。
可选地,该用户设备在该M个波束中检测出信噪比SNR小于信号传输门限SNRthd的波束,并将该信噪比SNR小于该信号传输门限SNRthd的波束的标识和各波束的信道质量信息通过检测反馈信息发 送至基站。
需要说明的是,针对上述三种可选的反馈方式,用户设备可以执行其中一种,例如,该用户设备只反馈存在重复覆盖的波束的标识,此时,基站通过本发明上一方法实施例中步骤S403所描述的方式一确定需要进行调整的Z1个波束;另外,用户设备也可以执行上述三种可选的反馈方式中的多种方式,由基站通过本发明上一方法实施例中步骤S403所描述的方式一至方式三确定需要进行调整的Z1个波束,本发明对此不做限定。例如,该用户设备反馈存在重复覆盖的波束的标识以及存在波束间干扰问题的波束的标识,这样,针对存在3个波束覆盖的用户设备,若该用户设备通过检测确定波束1和波束2满足信号传输条件,波束3不满足信号传输条件,则该用户设备可以无需再判断波束1和波束2是否存在干扰,只需判断该波束3与该波束1和该波束2是否存在干扰,若是,则该用户设备反馈该波束1、该波束2和该波束3的标识。
S1103、该用户设备向该基站发送该检测反馈信息,以便该基站在接收到至少一个用户设备发送的检测反馈信息后,获取所有该检测反馈信息携带的Z个波束的标识,并在该Z个波束中确定需要进行调整的Z1个波束,对该Z1个波束对应的Z1个天线子阵进行至少一次调整。
需要说明的是,基站可以接收多个用户设备发送的检测反馈信息,其中,覆盖每个用户设备的波束个数可能不同,每个用户设备反馈的波束标识的个数也可能不同,也就是说,针对不同的用户设备,其对应的M值和m值可能不同。
其中,Z为大于或等于m的正整数,Z1为小于或等于Z的正整数。
具体地,该基站根据该用户设备发送的该检测反馈信息对波束的分布进行调整的过程可参照本发明上一方法实施例图5至图10对应的描述,此处不再赘述。
可选地,该用户设备接收基站发送的波束确认信息,根据该波 束确认信息停止波束检测。
具体地,该基站在每次调整波束的分布后,通过调整后的波束发送波束信息继续指示用户设备进行波束检测,通过循环多次的调整,直到该基站根据该用户设备反馈的检测信息确定该Z个波束中不存在需要进行调整的波束,或者该基站的调整次数达到预设的调整次数门限,此时,该基站停止对波束的调整,并向所有该基站的波束覆盖范围内的用户设备发送波束确认信息,以便用户设备接收到该波束确认信息后,停止波束检测和信息反馈,这样,基站和用户设备相互确认完成,可以进行后续的资源分配和数据通信过程。
采用上述方法,至少一个用户设备向基站发送的检测反馈信息,以便基站根据该检测反馈信息确定需要进行调整的波束,并对生成该波束的天线子阵进行调整,使得调整后的天线子阵生成的波束重复覆盖减少、波束间干扰减小,或者使得更多的波束满足信号传输门限,提高系统的容量,提升了用户体验。
为了使本领域技术人员能够更清楚地理解本发明实施例提供的一种波束调整的方法的技术方案,下面通过具体的实施例对本发明提供的另一个波束调整的方法进行详细说明,其中,该实施例是以对波束重复覆盖问题的调整为例进行说明的,如图12所示,包括:
S1201、基站通过多个波束发送波束信息。
具体地,如图2所示,该基站利用波束1至波束N每一个波束发送波束信息。该波束信息包括对应波束的波束标识,以及信道检测信息,其中,较优的,每个波束的信道检测信息之间为不相关信号。
S1202、用户设备接收任一波束的波束信息,并根据该波束信息中的信道检测信息进行波束检测,得到检测反馈信息。
具体地,该用户设备根据该信道检测信息检测对应波束的信道质量,并通过检测识别接收信号对应波束的波束标识。
示例地,如图2所示,该基站发出的波束的覆盖范围内的任一用户设备在接收到任一波束的波束信息时,根据该波束信息中的信道检测信 息进行波束检测,检测覆盖该用户设备的所有的波束是否满足信号传输的条件,并将满足信号传输条件的波束的标识和各波束的信道质量信息作为检测反馈信息中携带的信息。
S1203、至少一个用户设备向该基站发送检测反馈信息。
示例地,该至少一个用户设备为该基站发出的全部波束所能覆盖的用户设备。
S1204、该基站根据该检测反馈信息获取该至少一个用户设备反馈的所有Z个波束的标识以及该Z个波束的信道质量信息。
其中,Z为大于或者等于1的正整数。
S1205、该基站在该Z个波束标识中确定需要进行调整的Z1个波束。
其中,Z1为大于或等于1,且小于或等于Z的正整数。
示例地,如图3所示,波束i和波束K均满足用户设备的信号传输条件,由于波束i和波束k同时覆盖UE4、UE5和UE6,这样,UE4至UE6向基站发送的检测反馈信息中均同时包括波束i和波束k的标识。此时,该基站根据该所有用户设备反馈的波束标识和各波束的信道质量信息进行联合统计分析,确定波束i和波束k存在重复覆盖的问题,需要进行波束调整。
S1206、该基站确定该Z1个波束对应的Z1个天线子阵是否相邻。
示例地,预先设置该基站发出的每个波束的波束标识,并在该基站中存储每个波束的波束标识与生成该波束的天线子阵的对应关系,则该基站在确定需要进行调整的Z1个波束后,根据该Z1个波束的标识确定生成该Z1个波束的天线子阵,并判断该Z1个波束是否相邻,若是,执行步骤S1207和步骤S1208或者步骤S1209和步骤S1210,若否,执行步骤S1211和步骤S1212。
S1207、该基站将该Z1个天线子阵合并为一个联合天线子阵。
S1208、该基站通过该联合天线子阵生成的波束发送波束信息。
其中,该波束信息包括调整后天线子阵生成的波束的波束标识以及信道检测信息。
需要说明的是,步骤S1207和步骤S1208是本发明实施例中基站调整波束分布的一种可选的方式,具体可参照图5和图6对应的描述,此处不再赘述。
S1209、该基站对该Z1个天线子阵的阵列单元进行重新分配组成波束宽互不相同的U个天线子阵。
其中,U为大于或等于2的正整数。
S1210、该基站通过该U个天线子阵生成的波束发送波束信息。
其中,该波束信息包括调整后天线子阵生成的波束的波束标识以及信道检测信息。
需要说明的是,步骤S1209和步骤S1210是本发明实施例中基站调整波束分布的一种可选的方式,具体可参照图7和图8对应的描述,此处不再赘述。
S1211、该基站调整该Z1个不相邻的天线子阵的波束生成方式。
S1212、该基站通过该Z1个不相邻的天线子阵调整后的波束发送波束信息。
其中,该波束信息包括调整后天线子阵生成的波束的波束标识以及信道检测信息。
需要说明的是,步骤S1211和步骤S1212是本发明实施例中基站调整波束分布的一种可选的方式,具体可参照图9对应的描述,此处不再赘述。
S1213、该用户设备接收该基站通过调整后的波束发送的携带信道检测信息的波束信息。
S1214、该用户设备根据该信道检测信息再次进行波束检测。
S1215、该用户设备向该基站发送再次波束检测得到的检测反馈信息。
上述步骤S1213至步骤S1215具体可参照步骤S1201至步骤S1203。该基站在每次调整波束的分布后,通过调整后的波束发送波束信息继续指示用户设备进行波束检测。
S1216、该基站通过该检测反馈信息确定调整后的波束中不存在需要调整的波束,并停止波束调整。
S1217、该基站向该用户设备发送波束确认信息。
S1218、该用户设备根据该波束确认信息停止波束检测。
具体地,上述步骤只是通过一次循环调整进行说明,在具体实施过程中,可通过循环多次的调整,直到该基站根据该用户设备反馈的检测信息确定当前的波束中不存在需要调整的波束,此时,该基站停止对波束的调整,并向该用户设备发送波束确认信息,该用户设备接收到该波束确认信息后,停止波束检测和信息反馈,这样,基站和用户设备相互确认完成,可以进行后续的资源分配和数据通信过程。
在本发明实施例一种可能的实现方式中,基站可预设调整次数门限,并在进行波束调整过程中对调整次数进行计数,当调整次数达到该调整次数门限时,若仍然存在需要调整的波束,则该基站根据最后一次的调整结果,进行资源分配。
另外,上述步骤是针对波束重复覆盖问题的调整,本发明还可以对波束分布存在的波束间干扰,以及信道质量问题进行调整,其方法步骤可参照上述步骤S1201至步骤S1208,其中,对于信道质量问题的调整方式,可以参照基站侧方法实施例对于图10的相关描述,此处不再赘述。本发明还可以同时解决波束重复覆盖,波束间干扰和信道质量问题,例如,在上述步骤S1203中,用户设备同时检测存在波束间干扰的波束和SNR小于信号传输门限的SNRthd的波束,并将符合条件的波束的标识以及各波束的信道质量信息作为检测反馈信息中携带的信息发送至该基站,由该基站确定需要进行调整的至少一个区域,以及该区域存在的波束分布问题,例如,基站确定需要进行信道质量调整第一区域,该第一区域包括Z1个波束,以及确定需要进行重复覆盖问题调整的第二区域,该第二区域包括Z2个波束,该Z2个波束与该Z1个波束之间无相同的波束,并参照上述步骤S1201至步骤S1208分别对该Z1个波束和该Z2个波束进行调整。
这样,用户设备向基站发送检测反馈信息,以便基站根据该检测反馈信息确定需要进行调整的波束,并对生成该波束的天线子阵进行调整,使得调整后的天线子阵生成的波束重复覆盖减少、波束间干扰减小,或者使得更多的波束满足信号传输门限,提高系统的容量,提升了用户体验。
本发明实施例提供一种基站13,对应上述图4的方法实施例,该基站13的各个功能单元均可用于上述方法步骤,如图13所示,该基站13包括:
发送单元131,用于通过多个波束发送波束信息。
其中,该波束信息包括对应波束的波束标识和信道检测信息,以便用户设备根据该信道检测信息对覆盖该用户设备的波束进行检测,得到检测反馈信息。
接收单元132,用于接收至少一个该用户设备发送的该检测反馈信息。
解析单元133,用于获取该检测反馈信息携带的Z个波束的标识,Z为大于或等于1的正整数。
确定单元134,用于在该Z个波束中确定需要进行调整的Z1个波束,Z1为小于或等于Z的正整数。
调整单元135,用于对该Z1个波束对应的Z1个天线子阵进行至少一次调整。
可选地,该发送单元131具体用于,通过高频段或者低频段向该至少一个用户设备发送该波束信息。
具体地,处于该基站发出的波束的覆盖范围内的任一用户设备在获取到所述信道检测信息后,对覆盖该用户设备的波束进行检测,例如,覆盖该用户设备的波束为M个,M为大于或等于1的正整数,则该用户设备将该M个波束中符合条件的m个波束的标识通过检测反馈信息发送至该基站,其中,符合条件的m个波束的标识包括满足该用户设备的信号传输条件的波束的标识,和/或,信噪比SNR之 差处于预设范围内的至少两个波束,和/或,信噪比SNR小于信号传输门限SNRthd的波束的标识。
进一步地,该基站从每一个用户设备发送的检测反馈信息中获取波束标识,例如,两个用户设备向基站发送检测反馈信息,其中,第一用户设备发送的检测反馈信息中包括m1个波束标识,第二用户设备发送的检测反馈信息中包括m2个波束标识,此时,若该m1个波束标识与该m2个波束标识中无相同的波束标识,则该基站从该第Z=m1+m2个波束;若该m1个波束标识与该m2个波束标识中包含相同的波束标识,则该基站从该第一用户设备和该第二用户设备发送的检测反馈信息中可获取到Z<m1+m2个波束。
进一步地,该基站在该Z个波束中确定需要进行调整的Z1个波束包括以下三种方式:
方式一、该Z个波束包括满足该用户设备的信号传输条件的波束,该检测反馈信息包括该Z个波束的信道质量信息,该确定单元134具体用于,根据该Z个波束的标识和该Z个波束的信道质量信息在该Z个波束中确定需要进行重复覆盖问题调整的Z1个波束。
其中,该用户设备能接收到的多个满足该用户设备的信号传输条件的波束之间存在重复覆盖问题。
如图3所示,波束i和波束K均满足用户设备的信号传输条件,由于波束i和波束k同时覆盖UE4、UE5和UE6,这样,UE4至UE6向基站发送的检测反馈信息中均同时包括波束i和波束k的标识。此时,该基站根据该所有用户设备反馈的波束标识以及各波束的信道质量信息进行联合统计分析,确定波束i和波束k存在重复覆盖的问题,需要进行波束调整。
方式二、该Z个波束包括信噪比SNR之差处于预设范围内的至少两个波束,该检测反馈信息包括该Z个波束的信道质量信息,该确定单元134具体用于,根据该Z个波束的标识和该Z个波束的信道质量信息在该Z个波束中确定需要进行波束间干扰问题调整的Z1个波束,其中,该用户设备能够接收到的信噪比SNR之差处于预设 范围内的至少两个波束之间存在波束间干扰问题。
在本发明实施例一种可选地的实现方式中,所述存在波束间干扰问题的多个波束均不满足用户设备的信号传输条件的波束,此时,由于该多个波束均不能为用户设备服务,该基站可以不对该多个波束进行调整,本发明对此不做限定。
在本发明另一种可选地实现方式中,所述存在波束间干扰问题的多个波束中包括不满足用户设备的信号传输条件的波束,也包括满足用户设备的信号传输条件的波束,或者所述存在波束间干扰问题的多个波束均满足用户设备的信号传输条件的波束。
如图3所示,波束i满足用户设备的信号传输条件,波束K不满足用户设备的信号传输条件,但是对该波束i造成干扰,例如,该波束i的SNR大于该SNRthd,该波束k的SNR小于该SNRthd,且该波束i与该波束k之间的SNR之差在一定的干扰范围之内,这样,UE4至UE6向基站发送的检测反馈信息中均同时包括波束i和波束k的标识。此时,该基站根据该所有用户设备反馈的波束标识以及各波束的信道质量信息进行联合统计分析,确定波束i和波束k存在波束间干扰的问题,需要进行波束调整。
方式三、该Z个波束包括信噪比SNR小于信号传输门限SNRthd的波束,该检测反馈信息包括该Z个波束的信道质量信息,该确定单元134具体用于,根据该Z个波束的标识和该Z个波束的信道质量信息在该Z个波束中确定需要进行信道质量调整的Z1个波束。
具体地,任一用户设备在检测到覆盖该设备的第一波束的SNR小于该信号传输门限SNRthd时,该用户设备将该第一波束的标识反馈至该基站,则该基站确定该第一波束对应的第一天线子阵的相邻天线子阵,若该相邻天线子阵对应的波束的信噪比SNR大于该信号传输门限SNRthd,则确定该第一波束与该相邻天线子阵对应的波束为需要进行信道质量调整的Z1个波束。
这样,当用户设备不存在满足其信号传输条件的波束时,可以将覆盖该用户设备的波束中SNR最大的波束标识反馈至基站,此时, 该SNR最大的波束即为上述第一波束。
需要说明的是,上述三种方式是基站根据用户设备不同的反馈方式进行的三种确定需要调整的Z1个波束的方式,在具体实施中,用户设备可以在检测反馈信息中携带重复覆盖波束的标识、存在波束间干扰的波束的标识、SNR小于信号传输门限SNRthd的波束的标识中的至少一种,这样,根据至少一个用户设备的反馈由该基站按照上述三种方式中的至少一种进行分析确定波束分布存在的问题,其中,该基站在分析波束分布存在的问题时,可以根据局部区域的总容量为准则和/或以用户体验为准则。
另外,该基站还可以同时在该Z个波束中确定其他需要进行调整的Z2个波束,其中,该Z2个波束与该Z1个波束之间无相同的波束,该Z2个波束与该Z1个波束可以存在不同的波束分布问题,例如,该Z1个波束为相邻的波束1,波束2和波束3,其中波束1对应的SNR小于SNRthd,需要进行信道质量的调整,该Z2个波束为波束4和波束5,该波束4和波束5重复覆盖相同的用户设备,需要进行重复覆盖问题的调整。
进一步地,该基站在确定需要进行调整的Z1个波束后,确定生成该Z1个波束的Z1个天线子阵,示例地,预先设置该基站发出的每个波束的波束标识,并在该基站中存储每个波束的波束标识与生成该波束的天线子阵的对应关系,则该基站在确定需要进行调整的Z1个波束后,根据该Z1个波束的标识通过该对应关系确定生成该Z1个波束的天线子阵。
进一步地,针对上述方式一和方式二,该调整单元135具体用于,在该Z1个天线子阵相邻时,将该Z1个天线子阵的阵列单元合并为一个联合天线子阵,通过该联合天线子阵生成的一个联合波束覆盖用户设备。
示例地,该至少一个用户设备向基站发送的反馈检测信息中包括波束i和波束k,该基站确定该波束i和波束k之间存在重复覆盖的问题或者波束间干扰的问题,则该基站根据该波束i和波束k 的标识确定生成该波束i和波束k的天线子阵i和天线子阵k,如图5所示,天线子阵i和天线子阵k相邻,则该基站将该天线子阵i的阵列单元和该天线子阵k的阵列单元合并组成一个新的联合子阵,并由该联合子阵生成的波束覆盖用户设备,如图6所示,此时,原本由波束i和波束k同时覆盖的用户设备UE4、UE5和UE6,均变为由一个联合波束覆盖,这样,避免了重复覆盖问题和波束间的干扰,保证了UE4、UE5和UE6的用户体验。
上述只是举例说明,在实际应用中,一个用户设备可能被两个以上波束覆盖,此时,该用户设备向该基站反馈的波束标识包括两个以上的波束标识,该基站可以将两个以上相邻的天线子阵合并为一个天线子阵,本发明对此不做限定。
可选地,针对上述方式一和方式二确定的波束分布问题,该调整单元135具体用于,在该Z1个天线子阵相邻时,对该Z1个天线子阵的阵列单元进行重新分配组成波束宽互不相同的U个天线子阵,U为大于或等于2的正整数。
示例地,该至少一个用户设备向基站发送的反馈检测信息中包括波束i和波束k,该基站确定该波束i和波束k之间存在重复覆盖的问题或者波束间干扰的问题,则该基站根据该波束i和波束k的标识确定生成该波束i和波束k的天线子阵i和天线子阵k,如图7所示,天线子阵i和天线子阵k相邻,则该基站将该天线子阵i的阵列单元和该天线子阵k的阵列单元进行重新分配,为该天线子阵i分配较少的阵列单元形成新的天线子阵a,为该天线子阵k分配较多的阵列单元形成新的天线子阵b,并由该天线子阵a和该天线子阵b生成的波束a和波束b覆盖用户设备,如图8所示,此时,原本波束i覆盖用户设备UE1至UE6,波束k覆盖用户设备UE4至UE8,变为由波束a覆盖用户设备UE1至UE6,波束b覆盖用户设备UE7和UE8,这样,原本由波束i和波束k同时覆盖的用户设备UE4、UE5和UE6,均变为由波束a覆盖,避免了重复覆盖问题和波束间干扰问题,保证了UE4、UE5和UE6的用户体验。
上述只是举例说明,基站将两个等波束宽的波束调整为一个宽波束和一个窄波束,本发明实施例对调整后新生成的波束数量不做限定,例如,该基站可以将两个波束对应的天线子阵重新分配为三个天线子阵。
可选地,针对上述方式一和方式二确定的波束分布问题,该调整单元135具体用于,在该Z1个天线子阵不相邻时,调整该Z1个不相邻的天线子阵的波束成型算法,改变该Z1个天线子阵生成的波束的波束宽度和/或波束指向。
示例地,该至少一个用户设备向基站发送的反馈检测信息中包括波束i和波束k,该基站确定该波束i和波束k之间存在重复覆盖的问题或者波束间干扰的问题,则该基站根据该波束i和波束k的标识确定生成该波束i和波束k的天线子阵i和天线子阵k,如图9所示,天线子阵i和天线子阵k不相邻,此时,该基站可以通过波束成型算法分别来调整波束i和波束k的波束指向和/或波束宽度。如图8所示,该波束a为该天线子阵i调整波束成型算法后生成的波束,该波束b为该天线子阵k调整波束成型算法后生成的波束。
可选地,针对上述方式三确定的波束分布的问题,该确定单元134具体用于,在该Z个波束中确定信噪比SNR小于该信号传输门限SNRthd的第一波束,并确定该第一波束对应的第一天线子阵的相邻天线子阵,若该相邻天线子阵对应的波束的信噪比SNR大于该信号传输门限SNRthd,则确定该第一波束与该相邻天线子阵对应的波束为需要进行信道质量调整的Z1个波束;该调整单元135具体用于,对该Z1个天线子阵的阵列单元进行重新分配,增加该第一天线子阵的阵列单元的数量,使得该第一波束的信噪比SNR大于该信号传输门限SNRthd,并且与调整后的该第一天线子阵相邻的天线子阵对应的波束的SNR仍然大于该SNRthd
值得说明的是,对于不同天线子阵生成的波束,由于经过的信道衰落和路径损耗不同,其对应的信道质量存在差别。对于信道质 量较好的信道对应的天线子阵,该天线子阵生成的波束覆盖范围内的用户设备接收到的信噪比满足信号传输的需求,例如,该用户设备接收到的SNR大于信号传输门限SNRthd;而对于信道质量较差的信道对应的天线子阵,该天线子阵生成的波束覆盖范围内的用户设备接收到的信噪比不满足信号传输的需求,例如,该用户设备接收到的信噪比SNR小于信号传输门限SNRthd,此时,该天线子阵无法用来为其覆盖的用户设备服务,造成资源的浪费。
而在本发明实施例中,用户设备根据该信道检测信息在检测覆盖该用户设备的波束的波束标识时,可以同时检测各波束对应的信道质量,并将携带各波束的波束标识和各波束对应的信道质量信息的检测反馈信息发送至基站,这样,该基站即可根据该波束标识获知覆盖该用户设备的波束对应的天线子阵,根据该信道质量信息即可获知该天线子阵对应的信道质量,这样,对于不存在满足其信号传输条件的波束的用户设备,该基站可以增强覆盖该用户设备的波束中SNR最大的波束的信道质量,使其满足信号传输条件,为该用户设备提供服务,避免了资源浪费。
以图10举例说明,若覆盖用户设备的天线子阵i、天线子阵j和天线子阵k相邻,且该基站由该信道质量信息确定该天线子阵i的对应的SNR为A1,该天线子阵j的对应的SNR为A2,该天线子阵k的对应的SNR为A3,且A1>=A2>=SNRthd>A3,由于该天线子阵k对应的信噪比SNR小于信号传输门限SNRthd,因此该天线子阵k无法用来为其覆盖的用户设备服务。此时,该基站将该天线子阵i、天线子阵j和天线子阵k的阵列单元进行重新分配,将更多的阵列单元分配给该天线子阵k,将较少的阵列单元分配给该天线子阵i和该天线子阵j,由此形成新的三个天线子阵i′、j′和k′,并由该天线子阵i′、j′和k′生成的波束覆盖该用户设备。
需要说明的是,该基站在一次调整后,可以继续指示该用户设备进行波束检测,并接收该用户设备发送新的三个天线子阵i′、j′和k′对应的信道质量,如图10中所示的A1′、A2′和A3′,则该基 站判断该A1′、A2′和A3′是否均大于或等于信号传输门限SNRthd,若是,则停止调整,若否,则该基站继续对该天线子阵i′、j′和k′的阵列单元进行重新分配,直到新生成的天线子阵对应的SNR均大于或等于该信号传输门限SNRthd
另外,在本发明实施例一种可能的实现方式中,基站可预设调整次数门限,并在进行波束调整过程中对调整次数进行计数,当调整次数达到该调整次数门限时,若仍然存在调整后的波束的SNR小于信号传输门限SNRthd,则该基站根据最后一次的调整结果,进行资源分配。
可选地,该确定单元134还用于,确定该Z个波束中不存在需要调整的波束,指示该调整单元停止对天线子阵的调整;该发送单元131还用于,向该至少一个用户设备发送波束确认信息,以便该至少一个用户设备根据该波束确认信息停止波束检测。
具体地,该基站在每次调整波束的分布后,通过调整后的波束发送波束信息继续指示用户设备进行波束检测,通过循环多次的调整,直到该基站根据该用户设备反馈的检测信息确定该Z个波束中不存在需要进行调整的波束,或者该基站的调整次数达到预设的调整次数门限,此时,该基站停止对波束的调整,并向所有该基站的波束覆盖范围内的用户设备发送波束确认信息,以便用户设备接收到该波束确认信息后,停止波束检测和信息反馈,这样,基站和用户设备相互确认完成,可以进行后续的资源分配和数据通信过程。
所属领域的技术人员可以清楚地了解到,为描述的方便和简洁,仅以上述各功能模块的划分进行举例说明,实际应用中,可以根据需要而将上述功能分配由不同的功能模块完成,即将装置的内部结构划分成不同的功能模块,以完成以上描述的全部或者部分功能。上述描述的系统,装置和单元的具体工作过程,可以参考前述方法实施例中的对应过程,在此不再赘述。
采用上述基站,该基站通过至少一个用户设备发送的检测反馈信息,确定需要进行调整的波束,并对生成该波束的天线子阵进行 调整,使得调整后的天线子阵生成的波束重复覆盖减少、波束间干扰减小,或者使得更多的波束满足信号传输门限,提高系统的容量,提升了用户体验。
本发明实施例提供一种用户设备14,对应上述图11的方法实施例,该用户设备14的各个功能单元均可用于上述方法步骤,如图14所示,该用户设备14包括:
接收单元141,用于接收基站通过波束发送的波束信息。
其中,该波束信息包括对应波束的波束标识和信道检测信息。
检测单元142,用于根据该信道检测信息对覆盖该用户设备的M个波束进行检测,得到检测反馈信息。
其中,该检测反馈信息包括m个波束的标识,m为大于或等于1,并且小于或等于M的正整数。
发送单元143,用于向该基站发送该检测反馈信息,以便该基站在接收到至少一个该用户设备发送的检测反馈信息后,获取所有该检测反馈信息携带的Z个波束的标识,并在该Z个波束中确定需要进行调整的Z1个波束,对该Z1个波束对应的Z1个天线子阵进行至少一次调整。
其中,Z为大于或等于m的正整数,Z1为小于或等于Z的正整数。
可选地,该检测反馈信息还包括该m个波束的信道质量信息,该检测单元142具体用于,在该M个波束中检测出满足该用户设备的信号传输条件的波束,其中,该m个波束的标识包括满足该用户设备的信号传输条件的波束的标识。
例如,该用户设备检测覆盖该用户设备的第一波束的信道质量,若该第一波束的信道质量满足信号传输的条件,则从该第一波束对应的波束信息中获取该第一波束的波束标识,该第一波束为覆盖该用户设备的任一波束,直到该用户设备将覆盖该用户设备的所有波束都检测完毕,将满足该用户设备的信号传输条件的波束的波束标 识和各波束的信道质量信息通过检测反馈信息发送至基站。
可选地,该检测反馈信息还包括该m个波束的信道质量信息,该检测单元142具体用于,在该M个波束中检测出信噪比SNR之差处于预设范围内的至少两个波束,其中,该m个波束的标识包括信噪比SNR之差处于预设范围内的至少两个波束的标识。
例如,存在2个波束覆盖该用户设备,则该用户设备可以通过判断波束1和波束2之间的SNR之差是否在预设的差值范围内,确定该该波束1和该波束2是否存在波束间干扰,若该波束1和波束2之间的SNR相近,则该波束1和波束2之间存在波束间干扰问题。
可选地,该检测反馈信息还包括该m个波束的信道质量信息,该检测单元142具体用于,在该M个波束中检测出信噪比SNR小于信号传输门限SNRthd的波束,其中,该m个波束的标识包括信噪比SNR小于该信号传输门限SNRthd的波束的标识。
需要说明的是,针对上述三种可选的反馈方式,用户设备可以执行其中一种,例如,该用户设备只反馈存在重复覆盖的波束的标识,此时,基站通过本发明上一方法实施例中步骤S403所描述的方式一确定需要进行调整的Z1个波束;另外,用户设备也可以执行上述三种可选的反馈方式中的多种方式,由基站通过本发明上一方法实施例中步骤S403所描述的方式一至方式三确定需要进行调整的Z1个波束,本发明对此不做限定。例如,该用户设备反馈存在重复覆盖的波束的标识以及存在波束间干扰问题的波束的标识,这样,针对存在3个波束覆盖的用户设备,若该用户设备通过检测确定波束1和波束2满足信号传输条件,波束3不满足信号传输条件,则该用户设备可以无需再判断波束1和波束2是否存在干扰,只需判断该波束3与该波束1和该波束2是否存在干扰,若是,则该用户设备反馈该波束1、该波束2和该波束3的标识。
进一步地,由基站根据至少一个用户设备发送的该检测反馈信息对波束的分布进行调整,其具体过程可参照基站侧方法实施例中图5至图10对应的描述,此处不再赘述。
需要说明的是,基站可以接收多个用户设备发送的检测反馈信息,其中,覆盖每个用户设备的波束个数可能不同,每个用户设备反馈的波束标识的个数也可能不同,也就是说,针对不同的用户设备,其对应的M值和m值可能不同。
可选地,该接收单元141还用于,接收基站发送的波束确认信息,并根据该波束确认信息指示该检测单元停止波束检测。
具体地,该基站在每次调整波束的分布后,通过调整后的波束发送波束信息继续指示用户设备进行波束检测,通过循环多次的调整,直到该基站根据该用户设备反馈的检测信息确定该Z个波束中不存在需要进行调整的波束,或者该基站的调整次数达到预设的调整次数门限,此时,该基站停止对波束的调整,并向所有该基站的波束覆盖范围内的用户设备发送波束确认信息,以便用户设备接收到该波束确认信息后,停止波束检测和信息反馈,这样,基站和用户设备相互确认完成,可以进行后续的资源分配和数据通信过程。
所属领域的技术人员可以清楚地了解到,为描述的方便和简洁,仅以上述各功能模块的划分进行举例说明,实际应用中,可以根据需要而将上述功能分配由不同的功能模块完成,即将装置的内部结构划分成不同的功能模块,以完成以上描述的全部或者部分功能。上述描述的系统,装置和单元的具体工作过程,可以参考前述方法实施例中的对应过程,在此不再赘述。
采用上述用户设备,至少一个该用户设备向基站发送的检测反馈信息,以便基站根据该检测反馈信息确定需要进行调整的波束,并对生成该波束的天线子阵进行调整,使得调整后的天线子阵生成的波束重复覆盖减少、波束间干扰减小,或者使得更多的波束满足信号传输门限,提高系统的容量,提升了用户体验。
