Description

一种干扰消除的反馈方法、相关装置及系统 技术领域
本发明涉及通信领域,尤其涉及一种干扰消除的反馈方法、相关装置及系统。
背景技术
随着无线业务的发展,人们对无线通信系统容量的要求越来越高。如何减少不同小区(基站)、不同用户设备之间的信号干扰,是进一步提升无线通信系统容量的关键之一。为了更好地解决不同小区间的用户干扰,在无线通信系统的研发和开发中,人们提出和实现了很多不同的技术,其中包括网侧协助的干扰消除(Network Assisted-Inteference Cancelation,NAIC),通过用户设备(User Equipment,UE)侧接收机对干扰小区信号进行重构,然后从接收信号中减去重构的干扰小区信号,消除小区间干扰提高干扰消除增益。干扰小区是对UE的服务小区形成干扰的小区。服务小区是为UE提供服务时的UE通过该服务小区接收信号的小区。干扰小区的测量方法及判断标准可参见现有技术的描述,此处不做赘述。
若UE侧的接收机为译码后干扰消除(post-decoding IC)的接收机,那么UE侧在进行干扰小区码块译码后的信号重构并消除时,会出现干扰小区码块译码错误的情况,即UE侧向网络侧反馈的服务小区信道质量指示(Channel Quality Indicator,CQI)会发生波动,然而网络侧不知道CQI的变化是由于信道质量的变化还是干扰小区码块译码的正误(正确或错误)导致的,从而导致网络侧的调度器低效;若UE侧的接收机为译码前干扰消除(pre-decoding IC)的接收机,虽然UE侧不做干扰小区码块译码,但仍旧会出现干扰消除后的CQI波动问题,导致网络侧对UE的调度效率不高,不能充分利用干扰消除增益。

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作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。
参见图1,是本发明提供的干扰消除的反馈方法的流程示意图,该方法包括:
步骤S100:根据接收信号生成服务小区的信道质量指示CQI;
具体地,所述接收信号包括服务小区信号和干扰小区信号,其中干扰小区对用户设备的服务小区形成干扰;
步骤S102:生成干扰消除指示信息,所述干扰消除指示信息用于指示用户设备对所述接收信号的干扰消除执行情况;
步骤S104:向网络侧反馈所述服务小区的信道质量指示CQI;
步骤S106:向网络侧反馈所述干扰消除指示信息,所述干扰消除指示信息和所述服务小区的信道质量指示CQI被所述网络侧用于进行所述用户设备调度。
在本发明各个实施例中,网络侧是一种概括的描述,其具体是一个网络设备,用来接收干扰消除指示信息,其可用来对用户设备做调度。具体地,所述用户设备可以使基站或基站控制器等实体。
进一步地,当UE的接收机为post-decoding IC接收机时,本发明实施例还包括:对干扰小区信号进行译码得到译码结果的步骤;具体地,步骤S100的具体实现可以包括如下情形:
a、当所述译码结果为正确,确定从接收信号中消除所述干扰小区信号的重构信号,以干扰消除后生成的信道质量指示CQI作为服务小区的信道质量指示CQI;所述干扰消除指示信息用于指示用户设备已经对接收信号进行干扰消除;即,具体地,只有当对干扰小区信号进行译码正确时才从接收信号中消除所述干扰小区信号的重构信号。
b、当所述译码结果为不正确,确定跳过从接收信号中消除所述干扰小区信号的重构信号的操作,并将未进行干扰消除而生成的信道质量指示CQI作为服务小区的信道质量指示CQI;所述干扰消除指示信息用于指示用户设备未对接收信号进行干扰消除;即,具体地,当对干扰小区信号进行译码错误时,不从接收信号中消除所述干扰小区信号的重构信号。
c、无论所述译码结果是否正确,均确定从接收信号中消除所述干扰小区信号的重构信号,以干扰消除后生成的信道质量指示CQI作为服务小区的信道质量指示CQI;所述干扰消除指示信息用于指示在执行干扰消除前的所述译码结果是否正确;即,具体地,不管对干扰小区信号进行译码是否正确,都从接收信号中消除所述干扰小区信号的重构信号,这种方法用于软重构干扰消除接收机中,即使译码错误,也能够部分消除干扰信号。当对干扰小区信号进行译码正确时,生成的干扰消除指示信息,用于指示对应反馈的信道质量指示CQI是干扰小区码块译码正确后进行干扰小区码块的软值重构并消除后的信道质量指示CQI;当对干扰小区信号进行译码错误时,生成的干扰消除指示信息,用于指示对应反馈的信道质量指示CQI是干扰小区码块译码错误后进行干扰小区码块的软值重构并消除后的信道质量指示CQI。
再进一步地,当UE的接收机为pre-decoding IC接收机时,UE对干扰小区的调度码块进行译码前的解调,并进行重构和消除。此时,本发明实施例中的步骤S100可以包括:
确定从接收信号中消除所述干扰小区信号的重构信号;
若干扰小区消除后的信道质量指示CQI大于未进行干扰消除而生成的信道质量指示CQI,则将干扰小区消除后的信道质量指示CQI作为服务小区的信道质量指示CQI;所述干扰消除指示信息用于指示用户设备已经对接收信号进行干扰消除;若干扰小区消除后的信道质量指示CQI小于未进行干扰消除 而生成的信道质量指示CQI,则将未进行干扰消除而生成的信道质量指示CQI作为服务小区的信道质量指示CQI;所述干扰消除指示信息用于指示用户设备未对接收信号进行干扰消除。
具体地,即pre-decoding IC接收机不需要干扰小区信号进行译码,那么UE在确定从接收信号中消除所述干扰小区信号的重构信号后,可以通过比较干扰小区消除后的CQI与干扰小区消除前的CQI大小,来决定向网络侧反馈的CQI是干扰小区消除后还是干扰小区消除前的CQI;进一步地,当干扰小区消除后的CQI大于干扰小区消除前的CQI,则向网络侧反馈干扰小区消除后的CQI,此时生成的干扰消除指示信息用于指示用户设备已经对接收信号进行干扰消除;;当干扰小区消除后的CQI小于干扰小区消除前的CQI,则向网络侧反馈干扰小区消除前的CQI,此时生成的干扰消除指示信息用于指示用户设备未对接收信号进行干扰消除。
再进一步地,UE侧可以与网络侧协商通过某条固有信道或新增一条信道来反馈所述干扰消除指示信息,优选地,步骤S104和步骤S106可以合并,即,UE侧可以向网络侧反馈服务小区的信道质量指示CQI的同时,反馈所述干扰消除指示信息。
进一步地,本发明实施例中的UE可以通过固有的高速专用物理控制信道(High Speed-Dedicated Physical Control Channel,HS-DPCCH)来反馈所述干扰消除指示信息;再具体地:
图2示出了现有技术中HS-DPCCH信道设计结构示意图,UE可以通过HS-DPCCH信道向网络侧反馈服务小区译码的ACK/NACK,以及服务小区的CQI;
图3示出了本发明实施例的HS-DPCCH信道设计的结构示意图,UE可以将步骤S102的干扰消除指示信息进行编码得到第一编码信息后,与服务小区译码的ACK/NACK进行编码后得到的第二编码信息进行级联,放在第一个时隙上,那么UE通过高速专用物理控制信道,在向网络侧反馈服务小区译码的ACK/NACK,以及CQI的同时,还向网络侧反馈了本发明实施例中的干扰消除指示信息。
可理解的,当本发明实施例中的干扰消除指示信息可以为干扰消除肯定确 认ACK信息或者干扰消除否定确认NACK信息时;具体地:
当UE侧需要对干扰小区信号进行译码时,若译码正确,则生成干扰消除肯定确认ACK信息,用于指示对应反馈的所述信道质量指示CQI是干扰消除后的信道质量指示CQI,或者指示对应反馈的信道质量指示CQI是干扰小区码块译码正确后进行重构并消除后的信道质量指示CQI;当干扰小区码块译码错误,则生成干扰消除否定确认NACK信息,用于指示对应反馈的信道质量指示CQI是干扰消除前的信道质量指示CQI,或者指示对应反馈的信道质量指示CQI是干扰小区码块译码错误后进行重构并消除后的信道质量指示CQI;
当UE侧不需要对干扰小区信号进行译码时,若干扰小区消除后的CQI大于干扰小区消除前的CQI,则生成干扰消除肯定确认ACK信息,用于指示对应反馈的信道质量指示CQI是干扰消除后的信道质量指示CQI;若干扰小区消除后的CQI小于干扰小区消除前的CQI,则生成干扰消除否定确认NACK信息,用于指示对应反馈的信道质量指示CQI是干扰消除前的信道质量指示CQI。
再具体地,本发明实施例中的干扰小区信号可以包括至少两个干扰码块,所述干扰消除指示信息可以包括与至少两个干扰码块分别对应的至少两个干扰消除指示信息;所述至少两个干扰码块可以包括至少两个干扰小区各自的干扰码块或者一个干扰小区至少两个干扰码块;
那么上述将所述干扰消除指示信息进行编码得到第一编码信息的步骤可以包括:将至少两个干扰消除指示信息进行联合编码得到第一编码信息。
需要说明的是,本发明实施例中UE使用图3所示的HS-DPCCH信道设计向网络侧反馈干扰消除指示信息,既可以利用了固有的信道(即在固有信道上做一些小改动),又由于服务小区并不需要利用所述干扰消除指示信息进行重传控制,因此干扰消除指示信息可以使用相对于服务小区ACK较小的功率进行发送,非常有利于实施;
另外,将干扰消除指示信息进行编码后再与服务小区译码的ACK/NACK进行编码后的编码码字进行级联,考虑了干扰小区调度多输入多输出(Multiple-Input Multiple-Out-put,MIMO)时的情形,避免了降低服务小区ACK的解码性能。
可理解地,本发明实施例中UE向网络侧反馈干扰消除指示信息的方案不限于使用图3所示的HS-DPCCH信道设计,只要是UE侧与网络侧共同协商好反馈方案即可,这里不再赘述。
通过实施本发明实施例,向网络侧反馈干扰消除指示信息,解决了现有技术中由于NAIC下CQI波动,导致的网络侧调度器低效的问题,实现了网络侧对UE进行更高效的调度,充分利用干扰消除增益。
上述详细阐述了本发明实施例的干扰消除的反馈方法,下面为了便于更好地实施本发明实施例的上述方案,相应地,下面还提供一种调度用户设备的方法;
如图4示出的本发明调度用户设备的方法的第一实施例的流程示意图,包括:
步骤S400:接收用户设备发送的干扰消除指示信息;
具体地,所述干扰消除指示信息用于指示用户设备对所述接收信号的干扰消除执行情况;其中,所述用户设备的接收信号包括服务小区信号和干扰小区信号,其中干扰小区对用户设备的服务小区形成干扰;
步骤S402:接收用户设备发送的服务小区的信道质量指示CQI;
步骤S404:根据所述干扰消除指示信息和所述服务小区的信道质量指示CQI进行用户设备调度。
具体地,用户设备UE侧具体如何生成并反馈所述干扰消除指示信息,可以参考上述图1至图3实施例所述的实现方式,这里不再赘述。参考上述图1至图3实施例,本发明实施例中的干扰消除指示信息可以包括如下几种情况:
a、干扰消除指示信息可以用于指示用户设备已经对接收信号进行干扰消除,所述服务小区的信道质量指示CQI为用户设备对接收信号进行干扰消除后生成的信道质量指示CQI。该干扰消除指示信息还可以具体用于指示用户设备已经在对干扰小区信号译码正确后对接收信号进行干扰消除。
b、干扰消除指示信息用于指示用户设备未对接收信号进行干扰消除,所述服务小区的信道质量指示CQI为未进行干扰消除而生成的信道质量指示CQI。该干扰消除指示信息还可以具体用于指示用户设备在对干扰小区信号译 码不正确后未对接收信号进行干扰消除。
c、干扰消除指示信息用于指示用户设备在执行干扰消除前的干扰小区的译码结果是否正确,所述服务小区的信道质量指示CQI为用户设备对接收信号的信道质量指示CQI进行干扰小区消除后生成的干扰消除后的信道质量指示CQI。
网络侧可以根据所述干扰消除指示信息,对UE反馈的CQI进行修正后再调度UE,从而实现了充分利用了干扰消除的增益。
下面进一步地,结合图5至图8,举例详细说明网络侧根据UE反馈的所述干扰消除指示信息进行用户设备调度的实现方式:
如图5示出的本发明调度用户设备的方法的第二实施例的流程示意图,当所述用户设备需要进行干扰小区码块译码时,调度用户设备的方法包括:
步骤S500:接收用户设备发送的干扰消除指示信息;
具体地,该干扰消除指示信息可以为指示用户设备已经在对干扰小区信号译码正确后对接收信号进行干扰消除,或者指示用户设备在对干扰小区信号译码不正确后未对接收信号进行干扰消除;
步骤S502:根据用户设备对干扰小区的译码结果统计所述用户设备反馈的对干扰小区译码的正确概率;
具体地,例如网络侧统计某段时间内用户设备反馈的10次信息中,8次是译码正确信息,2次是译码错误信息,那么得出用户设备反馈的对干扰小区码块译码的正确概率为80%,对干扰小区码块译码的错误概率为20%。
步骤S504:根据统计的所述正确概率,将干扰小区消除后的信道质量指示CQI以及未对接收信号进行干扰小区消除的信道质量指示CQI进行加权平均;
具体地,例如上述得出的用户设备反馈的对干扰小区码块译码的正确概率为80%,对干扰小区码块译码的错误概率为20%,那么分别利用该80%和20%对干扰小区消除后对应的信道质量指示CQI以及干扰小区消除前对应的信道质量指示CQI进行加权平均。
步骤S506:以加权平均后的信道质量指示CQI对所述用户设备进行调度。
如图6示出的本发明调度用户设备的方法的第三实施例的流程示意图,当所述用户设备需要进行干扰小区码块译码时,调度用户设备的方法包括:
步骤S600:接收用户设备发送的干扰消除指示信息;
具体地,该干扰消除指示信息可以为指示用户设备在执行干扰消除前的干扰小区的译码结果是否正确;
步骤S602:根据用户设备对干扰小区的译码结果统计所述用户设备对干扰小区译码的正确概率;
具体地,例如网络侧统计某段时间内用户设备反馈的10次信息中,8次是译码正确后进行重构并消除信息,2次是译码错误后进行重构并消除信息,那么得出用户设备反馈的对干扰小区码块译码的正确概率为80%,对干扰小区码块译码的错误概率为20%。
步骤S604:根据统计的所述正确概率,将用户设备的干扰小区码块译码正确并进行干扰消除后生成的信道质量指示CQI以及用户设备干扰小区码块译码错误并进行干扰消除后生成的信道质量指示CQI进行加权平均;
具体地,例如上述得出的用户设备反馈的对干扰小区码块译码的正确概率为80%,对干扰小区译码的错误概率为20%,那么分别利用该80%和20%对干扰小区码块译码正确后进行重构并消除后对应的CQI以及干扰小区码块译码错误后进行重构并消除后对应的CQI进行加权平均。
步骤S606:以加权平均后的信道质量指示CQI对所述用户设备进行调度。
如图7示出的本发明调度用户设备的方法的第四实施例的流程示意图,当所述用户设备需要进行干扰小区码块译码时,调度用户设备的方法包括:
步骤S700:接收用户设备发送的干扰消除指示信息;
具体地,该干扰消除指示信息可以为指示用户设备已经在对干扰小区信号译码正确后对接收信号进行干扰消除;或者指示用户设备在对干扰小区信号译码不正确后未对接收信号进行干扰消除;或者指示用户设备在执行干扰消除前的干扰小区的译码结果是否正确;
步骤S702:根据用户设备对干扰小区的译码结果统计在预设的一段时间内所述用户设备干扰小区能够译码正确的平均传输块大小信息;
具体地,当网络侧(即服务小区)知道干扰小区UE的传输格式时(即,干扰小区和服务小区位于同一个NB上,或者是C-RAN架构下),网络侧可以根据所述干扰消除指示信息,并根据预设的一段时间内对应的干扰小区调度的传输块大小信息,统计该一段时间内(即最近若干帧数据)干扰小区码块译码的能够译码正确时对应的TBS大小信息(即平均每帧对应的TBS大小);
步骤S704:通过统计的平均传输块大小信息来确认所述用户设备的干扰消除能力,以调整所述服务小区的信道质量指示CQI;
具体地,例如步骤S702中统计最近若干帧中干扰小区码块译码正确时对应的平均每帧对应的TBS大小,那么该平均每帧对应的TBS大小可以代表该UE的干扰消除能力,网络侧可以通过判断干扰小区下一帧将要调度的TBS大小是否大于所述平均每帧对应的TBS大小,来判断UE的干扰消除能力;若判断干扰小区下一帧将要调度的TBS大小大于所述平均每帧对应的TBS大小时,则表明UE很可能干扰小区码块译码错误,UE的干扰消除能力被高估了,这时服务小区将降低信道质量指示CQI,使用较低的CQI来调度UE;若判断判断干扰小区下一帧将要调度的TBS大小小于所述平均每帧对应的TBS大小时,则表明UE很可能干扰小区码块译码正确,UE的干扰消除能力被低估了,这时服务小区将提高信道质量指示CQI,使用较高的CQI来调度UE;
步骤S706:使用调整后的信道质量指示CQI并对所述用户设备进行调度。
如图8示出的本发明调度用户设备的方法的第五实施例的流程示意图,当所述用户设备不需要进行干扰小区码块译码时,调度用户设备的方法包括:
步骤S800:接收用户设备发送的干扰消除指示信息;
具体地,指示用户设备已经对接收信号进行干扰消除,所述服务小区的信道质量指示CQI为用户设备对接收信号进行干扰消除后生成的信道质量指示CQI;或者指示用户设备未对接收信号进行干扰消除,所述服务小区的信道质量指示CQI为未进行干扰消除而生成的信道质量指示CQI;
步骤S802:根据所述干扰消除指示信息,统计所述用户设备反馈的干扰小区消除后的信道质量指示CQI的概率;
