Description

一种通信方法、装置及系统
本申请要求于2021年05月31日提交中国专利局、申请号为202110600919.4、申请名称为“一种通信方法、装置及系统”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
本申请实施例涉及通信技术领域，尤其涉及一种通信方法、装置及系统。
背景技术
为了提高系统的吞吐性能以及用户的体验，可以采用多站协作的方式来为一个或多个终端设备服务。多站协作的方式有很多，如相干协作传输(coherent joint transmission，CJT)。在CJT方式下，多个网络设备可以同时为一个或多个终端设备服务，即多个网络设备同时向一个或多个终端设备发送相同的信息。在多站协作的情况下，网络设备可以计算得到调制和编码方案(modulation and coding scheme，MCS)，但计算MCS需要协作集外的干扰噪声，即干扰加噪声。因此，网络设备如何获取到干扰噪声已成为一个亟待解决的技术问题。
应理解，本申请此技术问题不限于多站协作，在单站的情况下，即一个网络设备为一个终端设备服务的情况下，也存在如何获取到干扰噪声的问题。
发明内容
本申请实施例公开了一种通信方法、装置及系统，用于网络设备获取干扰噪声。
第一方面公开一种通信方法，所述通信方法可以应用于终端设备，也可以应用于终端设备中的模块(例如，芯片)。下面以应用于终端设备为例进行描述。所述通信方法可以包括：接收来自网络设备的参考信号；根据所述参考信号确定第一信息，所述第一信息包括信道质量指示(channel quality indicator，CQI)，所述CQI为N个频域单元对应的CQI，所述N个频域单元为M个频域单元中的N个频域单元，所述M个频域单元为需要上报的频域单元，M为大于1的整数，N为大于或等于1且小于M的整数；向所述网络设备发送所述第一信息。
本申请实施例中，终端设备可以根据参考信号确定CQI，可以将CQI上报给网络设备，以便网络设备可以根据CQI确定干扰噪声。此外，终端设备向网络设备上报CQI时，并不需要向网络设备上报需要上报的所有频域单元对应的CQI，只需要向网络设备上报需要上报的所有频域单元中的部分频域单元对应的CQI，所需传输信息较少，因此，可以节约传输资源。
作为一种可能的实施方式，所述根据所述参考信号确定第一信息包括：根据所述参考信号确定N个干扰噪声和N个信道矩阵；根据所述N个干扰噪声、所述N个信道矩阵和N个预编码矩阵，确定N个信号干扰噪声比(signal to interference plus noise ratio，SINR)，所述N个信道矩阵为所述N个频域单元对应的信道矩阵；根据所述N个SINR确定所述CQI；所述第一信息还包括第一指示信息，所述第一指示信息用于指示所述N个信道矩阵。

具体实施方式
本申请实施例公开了一种通信方法、装置及系统，用于节约传输资源。以下分别进行详细说明。
为了更好地理解本申请实施例，下面先对本申请实施例的相关技术进行描述。
第五代移动通信技术(5th generation，5G)通信系统对系统容量、频谱效率等方面有了更高的要求，而制约频分双工(frequency division duplex，FDD)大规模(massive)多输入多输出(multiple input multiple output，MIMO)系统性能的一大瓶颈是下行信道状态信息(channel state information，CSI)获取。在FDD系统中，由于上下行信道存在较大的频点间隔， 上行信道与下行信道不满足直接互易关系，无法用上行信道信息来做准确的下行预编码。在传统的FDD系统中，需要用户设备(user equipment，UE)向网络设备反馈下行信道的CSI。请参阅图1，图1是本申请实施例公开的一种UE向网络设备反馈CSI的示意图。如图1所示，网络设备可以先通过信令向UE发送用于信道测量的配置信息。相应地，UE可以接收来自网络设备的配置信息，可以根据配置信息确定信道测量的时间及行为。之后网络设备可以向UE发送用于信道测量的导频。相应地，UE可以接收来自网络设备的导频，可以根据导频进行信道测量，可以根据测量的结果计算得到CSI，之后可以向网络设备发送CSI。相应地，网络设备可以接收来自UE的CSI，之后可以根据CSI向UE发送数据。CSI可以包括信道秩指示(rank indicator，RI)、信道质量指示(channel quality indicator，CQI)、预编码矩阵指示(precoding matrix indicator，PMI)等。网络设备可以根据RI确定向UE传输数据的流数，可以根据CQI确定向UE传输数据的调制和编码方案(modulation and coding scheme，MCS)，即调制阶数及信道编码的码率，可以根据PMI确定向UE传输数据的预编码矩阵。
为了提高系统的吞吐性能以及用户的体验，可以采用多站协作的方式来为一个UE服务。多站协作的方式有很多，例如相干协作传输(coherent joint transmission，CJT)、非相干协作传输(non coherent joint transmission，NCJT)等。请参阅图2，图2是本申请实施例公开的一种CJT和NCJT的示意图。如图2所示，在CJT方式下，多个传输接收点(transmitting and receiving point，TRP)可以同时为一个或多个UE服务(图2中只示意出了一个UE)，即多个TRP可以同时向一个或多个UE发送相同的信息。从UE的角度来看，协作集中的多个TRP可以等效看作一个大的网络设备。在NCJT方式下，不同TRP可以同时向一个或多个UE发送信息，也可以不同时向一个或多个UE发送信息，发送的信息可以相同，也可以不同。
在多站协作的情况下，网络设备可以计算得到调制和编码方案(modulation and coding scheme，MCS)，但计算MCS需要协作集外的干扰噪声，即干扰加噪声。因此，网络设备如何获取到协作集外的干扰噪声已成为一个亟待解决的技术问题。
为了解决上述问题，多站协作场景中，UE需要反馈协作集中各TRP信道以及协作集外其他TRP带来的干扰噪声，以便可以使能相干传输。
在实际实现中，CQI可以通过SINR进行衡量，SINR的计算方式可以表示如下：
Figure PCTCN2022091279-appb-000001
其中，当测量的为频域单元时，H eff为每个频域单元对应的等效信道矩阵，H为每个频域单元对应的信道矩阵，P为UE根据每个频域单元对应的信道矩阵确定的预编码矩阵，I+N为UE根据除用于测量的导频之外的干扰导频测得的干扰噪声，即干扰加噪声。上述公式中的I+N和H可以通过信道估计得到，P可以通过对H进行分解得到。应理解，本申请中的信道估计即信道测量。
目前，UE可以通过上述公式计算得到SINR，进而可以根据SINR确定CQI，之后可以向网络设备上报CQI，网络设备可以根据上报的CQI以及CQI表格确定MCS。如果使用上述方式使UE上报协作集外的干扰噪声，则需要UE反馈每个频域单元对应的CQI。本申请针对如何保证网络设备能够获取到干扰噪声的同时降低通信开销和资源浪费，提出了解决方案。
