Description

信道质量上报、接收方法、装置、终端、服务节点及介质 技术领域
本申请涉及无线通信网络，例如涉及一种信道质量上报、接收方法、装置、终端、服务节点及介质。
背景技术
在空口标准中，下行数据传输主要采用正交相移键控(Quadrature Phase Shift Keying，QPSK)的调制方式，调制方式单一、数据块大小跨度有限，因此不支持关于调制编码方式的信道质量指示(Channel Quality Indicator，CQI)上报。而随着新空口(New Radio，NR)技术的发展，通信系统支持的调制方式也得到了扩展，例如支持正交振幅调制(Quadrature Amplitude Modulation，QAM)，这种情况下将会产生更多的调制编码策略(modulation and coding schemes，MCS)，网络侧在调度和通信过程中需要综合考虑的因素也越来越多。由于CQI上报的方式单一、不灵活，无法适用于通信系统的不同场景，无法保证网络侧全面了解信道质量，进而影响到调度效率和通信性能。

具体实施方式
下面结合附图和实施例对本申请进行说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
在本申请实施例中，提供一种信道质量上报方法，终端基于CQI与信道质量参数的关联关系上报CQI，提高CQI上报的灵活性，服务节点可以准确获知信道质量，进而提高调度效率和通信性能。
图1为一实施例提供的一种信道质量上报方法的流程图，如图1所示，本实施例提供的方法包括步骤110和步骤120。
在步骤110中，确定第一信道质量指示CQI集合，所述第一CQI集合包括CQI与信道质量参数的关联关系，所述信道质量参数包括以下至少之一：调制方式、码率、频谱效率、调制编码策略MCS索引、传输块尺寸TBS索引以及重复次数。
本实施例中，所述码率可以表示为编码速率乘以1024。例如，如果编码码率为1/4，则所述码率等于256。
本实施例中，所述重复次数为物理下行共享信道(Physical downlink shared channel，PDSCH)的重复次数。本实施例中，所述MCS索引、TBS索引即为MCS序号、TBS序号。
在步骤120中，基于所述第一CQI集合上报CQI。
本实施例中，第一CQI集合可以表格的形式体现，第一CQI集合中存储了CQI与信道质量参数之间的关联关系，终端通过测量物理信道得到信道质量参数，据此可以将相应的CQI上报给服务节点，供服务节点进行调度决策。其中，信道质量参数可以包括调制方式、码率、频谱效率、MCS索引、TBS索引以及重复次数中的一种或多种。不同CQI通过不同的CQI索引表示，上报CQI即上报CQI索引。
本实施例中，终端基于第一CQI集合上报CQI，第一CQI集合关联于一种或多种信道质量参数，通过设置各CQI对应的信道质量参数的取值，使其在可能的取值范围内合理分布，尽可能均匀的反应不同的信道质量，使CQI之间译码需求的信噪比间隔均匀，并且使每个CQI码率和相对应的TBS更加匹配吻合，从而提高CQI上报的灵活性，上报准确的信道质量。并且所述第一CQI集合包含了较多的16QAM调制方式对应的CQI，有利于在高信噪比条件下提高数据传输效率。在此基础上，服务节点可以准确获知终端反馈的信道质量，进而提高调度效率和通信性能。
在一实施例中，第一CQI集合中，存在至少一个CQI索引，该CQI索引关联的码率等于预定义的第二CQI集合中的两个相邻CQI索引对应的码率的平均值。
本实施例中，在第一CQI集合中，至少存在一个CQI索引，该CQI索引对应的码率等于第二CQI集合中两个相邻CQI的码率的平均值，第二CQI集合由预定义。
本实施例中，所述码率的平均值等于非整数时，所述码率的平均值可以基于这个非整数值向上取整或向下取整。例如，如果码率的平均值等于251.5，那么，该码率的平均值可以取值为251或252。
