技术领域
本公开涉及通信技术领域,尤其涉及一种CSI报告方法、配置方法、终端及网络侧设备。
背景技术
大规模多输入多输出(Massive Multiple Input Multiple Output,Massive MIMO)技术作为新无线(New Radio,NR)接入技术的关键技术之一,能够利用更多的空间自由度提高系统容量,从而得到了广泛研究。
在大规模MIMO系统中,为了在网络侧设备中选择合适的传输接收点(Transmission Reception Point,TRP)来提高系统传输性能,网络侧设备需要获知各TRP的信道状态信息(Channel State Information,CSI),而CSI通常由终端测量得到,因此,终端需要将该CSI反馈给网络侧设备。
在相关技术中,每一个TRP分别向终端发送一个CSI配置信息,终端根据接收的配置信息分别对每一个TRP的CSI进行测量,并反馈测量到的CSI。从而达到根据终端测量的CSI选择传输质量好的一个或者多个TRP进行信号传输。
由此可知,相关技术中,各个TRP的CSI配置和反馈分别执行,使反馈CSI的成本高。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
本公开实施例所涉及到的终端可以包括各种具有无限通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的终端设备,移动台(Mobile Station,MS)等等。为方便描述,上面提到的设备统称为终端。
本公开实施例可以应用于第五代(5th Generation,5G)通信系统,所涉及到的传输接收点(Transmission Reception Point,TRP)可以是基站,其包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在长期演进(Long Term Evolution,LTE)系统中,称为演进的节点B(evolved Node B,eNB),在3G通信系统中,称为节点B(Node B)等等。此外,还可以适用于LTE系统后续的演进系统。需要说明的是,当本公开实施例的方案应用于未来可能出现的其他系统时,基站、终端的名称可能发生变化,但这并不影响本公开实施例方案的实施。在下述的实施例中,以TRP为执行主体,对本实施例的技术方案进行详细说明。
请参阅图1,是本公开实施例提供的一种CSI报告方法的流程图。该CSI报告方法应用于支持多传输接收点TRP的终端,如图1所示,所述报告方法 包括以下步骤:
步骤101、接收CSI报告配置消息,所述CSI报告配置消息包括资源指示字段,所述资源指示字段用于指示N组资源,所述N为大于或等于2的整数。
其中,所述N组资源与N个传输接收点TRP一一对应,所述N个TRP与所述终端可以进行信号传输,例如:终端201的附近设置有4个基站,分别为:TRP1、TRP2、TRP3以及TRP4,且该终端201可以利用TRP1、TRP2、TRP3以及TRP4中的任意一个或者多个的传输资源进行信号传输。
另外,所述终端接收的所述CSI报告配置消息,可以由所述N个TRP中的任意一个或者多个发送。
另外,与每一个TRP对应的资源组包括非零功率信道状态信息参考信号资源和/或信道状态信息干扰测量参考信号资源。其中,非零功率信道状态信息参考信号资源也可以称之为NZP CSI-RS Resource Setting,用于传输非零功率信号,该非零功率信号可以用于对该资源的信道测量;信道状态信息干扰测量参考信号资源也可以称之为CSI-IM Resource Setting,用于传输零功率信号,即不发送信号,而其他的TRP可以在该资源上发送信号,从而可以对该资源的进行干扰测量。
本步骤中,通过一条CSI报告配置消息中的资源指示字段,分别配置对N个TRP对应的用于CSI测量的N组资源,避免了分别各自独立的发送N个TRP的CSI报告配置消息,从而减少了CSI报告配置消息占用的资源,减小了开销。
步骤102、发送CSI报告消息,所述报告消息包括CSI承载字段,所述CSI承载字段用于携带依据所述N组资源测量得到的目标CSI。
另外,所述终端可以利用一个TRP进行单TRP(Single-TRP)传输,也可以利用至少两个TRP进行多TRP(Multi-TRP)传输,或者还可以进行Single-TRP/Multi-TRP自适应传输。
其中,对于Multi-TRP传输和Single-TRP/Multi-TRP自适应传输,TRP可以进行动态传输点选择(Dynamic Point Select,DPS)传输或者联合传输(Joint Transmission,JT)传输。
在相关技术中,对于Multi-TRP传输和Single-TRP/Multi-TRP自适应传输,由于终端不能够反馈测量到的CSI,从而使网络侧设备不能够从DPS和JT传输方式中选择性能更好的一种传输方式进行信号传输,从而降低了相关技术中的终端与网络侧设备之间信号传输的性能。
作为一种可选地实施方式,所述CSI报告配置消息还包括第一类型指示字段,所述第一类型指示字段用于指示CSI类型,所述目标CSI的类型为所述第一类型指示字段指示的CSI类型。
也就是说,网络侧设备可以指示终端进行特定类型的CSI的测量,而终端可以依据第一类型指示字段确定待测量的CSI的类型。
其中,终端接收到所述CSI报告配置消息后,根据所述第一类型指示字段指示的CSI类型进行CSI测量,对于未指示的CSI类型便可以不测量。
这种方式能够提高CSI测量的针对性,避免无效的测量。
本实施方式中,网络侧设备通过其发送的CSI报告配置消息中的第一类型指示字段,指示终端测量的目标CSI的类型。终端便可以仅对指示的CSI的类型进行测量与上报,从而避免终端对各个类型的CSI分别进行测量而浪费时间和提升测量CSI的成本。
作为一种可选地实施方式,所述CSI报告消息还包括第二类型指示字段,所述第二类型指示字段用于指示所述目标CSI的CSI类型。
其中,终端上报所述目标CSI的CSI类型,以供网络侧设备接收到所述目标CSI之后,根据其CSI类型选择合适的一个或者多个TRP进行信号传输。
例如:网络侧设备根据接收到的所述目标CSI及其CSI类型,判断各个TRP的效率、通信质量等,并根据判断结果选择合适的TRP与所述终端进行信号传输。
与上一实施方式的不同之处在于,本实施方式中,网络侧设备不需要在配置信息中指示目标CSI的CSI类型,而由终端直接上报目标CSI的CSI类型。这样,可以使网络侧设备接收到所述目标CSI之后,根据其CSI类型选择合适的一个或者多个TRP进行信号传输,避免网络侧设备混淆所述目标CSI的CSI类型而影响其判断结果的准确性。
这种方式下,终端可以自主决策其上报的CSI的类型,避免无效的上报。
例如,假定终端仅支持DPS传输,而不支持JT传输,则终端只需要上报DPS传输模式对应的CSI,而无需上报JT传输对应的CSI。
其中,所述CSI类型可以包括如下类型中的至少一个:使用单TRP进行传输时的CSI、使用多TRP进行传输时的CSI;
或者
所述CSI类型包括如下类型中的至少一个:使用单TRP进行传输时的CSI、使用多TRP进行DPS传输时CSI,以及使用多TRP进行联合传输时的CSI。
例如:如图2所示,小区中设置有TRP1、TRP2、TRP3以及TRP4这4个基站,且能够通过TRP1和TRP2与终端进行Multi-TRP传输。
其中,TRP1包括资源:NZP CSI-RS Resource Setting 1和CSI-IM Resource Setting 1。TRP2包括资源:NZP CSI-RS Resource Setting 2和CSI-IM Resource Setting 2。
所述CSI的类型包括仅以TRP1进行单点传输时测量得到的CSI 1、仅以TRP2进行单点传输时测量得到的CSI 2以及以TRP1和TRP2进行多点传输时测量得到的CSI 3。
其中,CSI 1可以通过以下方式测量得到:
终端使用NZP CSI-RS Resource Setting 1对TRP1进行Channel Measurement(信道测量,例如:TRP1在该资源上发非零功率参考信号),使用CSI-IM Resource Setting 1对TRP1进行Interference Measurement(干扰测量,例如:TRP1在该资源上发零功率参考信号,也即不发信号,其他TRP或小区在该资源上可能发信号),并根据信道测量和干扰测量的结果,计算出以TRP1进行单点传输的CSI 1。
另外,CSI 2可以通过以下方式测量得到:
终端使用NZP CSI-RS Resource Setting 2对TRP2进行Channel Measurement(信道测量,例如:TRP2在该资源上发非零功率参考信号),使用CSI-IM Resource Setting 2对TRP2进行Interference Measurement(干扰测量,例如:TRP2在该资源上发零功率参考信号,也即不发信号,其他TRP或小区在该资源上可能发信号),并根据信道测量和干扰测量的结果,计算出 以TRP2进行单点传输的CSI 2。
另外,CSI 3可以通过以下方式测量得到:
终端以NZP CSI-RS Resource Setting 1和NZP CSI-RS Resource Setting 2进行多点传输(即TRP1和TRP2进行多点传输)时的信道测量,使用CSI-IM Resource Setting 1和CSI-IM Resource Setting 2进行多点传输时的干扰测量,并根据信道测量和干扰测量的结果,计算出以TRP1和TRP2进行多点传输时的CSI 3。
具体的,以CSI包括信道质量指示(Channel Quality Indicator,CQI)为例。终端可以基于CSI-IM Resource Setting 1测量得到除了TRP1之外的其他TRP的干扰(如图3中所示的:I0+I2,其中,I2代表TRP2的干扰,I0代表除TRP1和TRP2之外的其他TRP的干扰);并基于CSI-IM Resource Setting 2测量得到除TRP2之外的其他TRP的干扰(如图3中所示的:I0+I1,其中I1代表TRP1的干扰);且终端可以基于其他的一些物理下行共享信道(Physical Downlink Shared Channel,PDSCH)(所有TRP在这些PDSCH上都可能在发送信号)测量得到如图3中所示的:I0+I1+I2。然后结合:I0+I2、I0+I1以及I0+I1+I2的值便可以计算得出I_0的具体数值。
另外,终端还可以基于NZP CSI-RS Resource Setting 1测量仅以TRP1进行DPS传输时的第一信道测量S1,并结合其干扰测量结果计算出仅以TRP1进行DPS传输时的CSI 1。
例如,通过公式:CQI 1=S1/I0+n,计算得出CQI 1的具体数值。其中,n为噪声参数。
以及终端基于NZP CSI-RS Resource Setting 2测量仅以TRP2进行DPS传输时的第二信道测量S2,并结合其干扰测量结果计算出仅以TRP2进行DPS传输时的CSI 2。
并通过公式:CQI 2=S2/I0+n,计算得出CQI 2的具体数值。其中,n为噪声参数。
另外,所述终端还可以基于NZP CSI-RS Resource Setting 1和基于NZP CSI-RS Resource Setting 2测量使用TRP1和TRP2进行JT传输时的第三信道测量(S1+S2),并结合其干扰测量结果计算以TRP1和TRP2进行联合传输 时的CSI 3。
并通过公式:CQI 3=(S1+S2)/I0+n,计算得出CQI 3的具体数值。其中,n为噪声参数。
最终,可以从CQI 1、CQI 2以及CQI 3中选择最大值,以此得出以TRP1进行DPS传输、以TRP2进行DPS传输以及以TRP1和TRP2进行JT传输中通信质量最好的传输方式。
当然,除了CQI之外,所述CSI还可以包括CSI-RS资源指示(CSI-RS Resource Indicator,CRI)、秩指示(Rank Indicator,RI)、预编码矩阵指示(Pre-coding Matrix Indicator,PMI)中的一种或者多种。
且计算CRI、RI、PMI的过程与计算CQI的过程相似,在此不再一一赘述。
本步骤中,终端向网络侧设备发送的CSI报告消息中具有依据N组资源测量得到的目标CSI,以供网络侧设备根据目标CSI选择合适的TRP以及合适的方式与终端进行信号传输,以避免相关技术中分别针对每一个TRP进行CSI测量并反馈CSI的方式造成的成本高的问题。
在本公开实施例中,支持多传输接收点TRP的终端接收CSI报告配置消息,所述CSI报告配置消息包括资源指示字段,所述资源指示字段用于指示N组资源,所述N为大于或等于2的整数;发送CSI报告消息,所述报告消息包括CSI承载字段,所述CSI承载字段用于携带依据所述N组资源测量得到的目标CSI。这样,终端仅通过一条CSI报告配置消息便能够反馈N个TRP的目标CSI,从而避免了N个TRP分别向终端发送CSI配置信息造成的成本高的问题。
请参阅图4,是本公开实施例提供的一种配置方法的流程图。该配置方法应用于网络侧设备,如图4所示,该配置方法包括以下步骤:
步骤401、发送信道状态信息CSI报告配置消息,所述CSI报告配置消息包括资源指示字段,所述资源指示字段用于指示N组资源,所述N为大于或等于2的整数。

当然,其还可以是所述N个TRP中其他性能较好的一个或者多个,例如:传输效率最高的。
本实施方式中,网络侧设备依据终端上报的目标CSI,选择CSI参数较优秀的目标TRP用于传输,从而提升所述网络侧设备与所述终端之间的传输性能。

本公开实施例与如图1所示CSI报告方法中的各个步骤呈对应关系,且能够取得相同的有益效果,为避免重复,在此不再赘述。
需要说明的是,如图1所示的CSI报告方法与如图4所示的配置方法可以相互配合以使网络侧设备向终端发送配置信息后,终端根据接收的配置信息检测相应TRP的CSI。
