背景技术Background technique
随着无线通信技术的不断发展和进步，通常使用自适应调制与编码(AdaptiveModulation and Coding，简称AMC)技术，其能够根据信道状况对调制与编码策略(Modulation and Coding Scheme，简称MCS)的等级进行调整，并确定调制阶数，以根据调制阶数对信道进行调制，保证信道的有效利用率。With the continuous development and progress of wireless communication technology, Adaptive Modulation and Coding (AMC) technology is usually used, which can adjust the level of Modulation and Coding Scheme (MCS) according to channel conditions. Adjust and determine the modulation order to modulate the channel according to the modulation order to ensure the effective utilization of the channel.
目前，在确定调制阶数时，将上一次确定的调制阶数与固定的步进值的和，确定为当前的调制阶数，根据当前的调制阶数对信道进行调制。但是，在根据上一次确定的调制阶数和固定的步进值确定当前的调制阶数时，调制阶数每次对应的步进值可能不相同，因此，通过固定的步进值确定的当前的调制阶数的精度较低，使得在根据当前的调制阶数对信道进行调制时，信道的有效利用率较低。At present, when determining the modulation order, the sum of the modulation order determined last time and the fixed step value is determined as the current modulation order, and the channel is modulated according to the current modulation order. However, when the current modulation order is determined according to the modulation order determined last time and the fixed step value, the step value corresponding to the modulation order may be different each time. The precision of the modulation order is lower, so that when the channel is modulated according to the current modulation order, the effective utilization rate of the channel is lower.

这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings.

The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

In the text description of this application, the character "/" generally indicates that the contextual object is an "or" relationship.
本申请实施例提供的技术方案可以应用于信道调制的场景中。当前的无线通信系统，调制与编码策略的通常制为不同传输速率的索引表，为了能够更好的适应信道的变化，自适应调制与编码技术在调制与编码策略等级选取中通常依赖于手段反馈的信道质量指示信息。从而实现了在信道状态好的情况下，传输更多的数据分组，而在信道质量较差的情况下，进行动态调整，降低传输速率，以适应信道状态的变化。The technical solutions provided in the embodiments of the present application can be applied to a channel modulation scenario. In current wireless communication systems, modulation and coding strategies are usually made into index tables of different transmission rates. In order to better adapt to channel changes, adaptive modulation and coding techniques usually rely on means feedback in the selection of modulation and coding strategy levels. channel quality indication information. Therefore, more data packets are transmitted when the channel state is good, and dynamic adjustment is performed to reduce the transmission rate when the channel quality is poor to adapt to the change of the channel state.
其中，自适应调制与编码技术的基本原理可参见图1所示，图1为本申请实施例提供的一种自适应调制与编码技术的原理示意图。根据图1所示，数据以分组的形式传输，对数据进行信道编码与调制得到编码调制后的数据，并通过信道将编码解调后的数据传输至接收端，接收端通过对编码解调后的数据进行解调解码处理，从而以分组的形式输出数据。The basic principle of the adaptive modulation and coding technology may be referred to as shown in FIG. 1 , which is a schematic diagram of the principle of an adaptive modulation and coding technology provided by an embodiment of the present application. As shown in Figure 1, data is transmitted in the form of packets, channel coding and modulation are performed on the data to obtain coded and modulated data, and the coded and demodulated data is transmitted to the receiving end through the channel. The data is demodulated and decoded, thereby outputting the data in the form of packets.
进一步地，在出现信道衰落的情况时，数据的接收端能够根据接收到的包括信道衰落的信号，通过固定门限算法确定下次调度采用的调制等级，具体的可参见图2所示，图2为本申请实施例提供的一种固定门限算法的流程示意图。根据图2所示，可以通过训练序列、离线仿真获得每个信道质量指示对应的矢量信噪比，接收端根据信道衰落以及噪声进行信道估计，将矢量信噪比映射为标量有效信噪比。并通过查找预设的阈值表确定映射信道质量指示的值，于下一个信道质量指示反馈周期反馈给发端，发端确认下次调度采用的调制等级。即发送端根据从收端反馈回来的信道状态信息，进行调制与编码策略的选择，在固定的调制编码方式集合中选取对应的传输速率和调制等级以及调制阶数，从而根据调制等级对数据分组进行编码与调制，从而保证在出现信道衰落的情况下进行数据传输时，能够充分的利用信道，提高数据传输的吞吐量。因此，确定调制阶数对于数据在信道中的输出尤为重要。Further, in the event of channel fading, the receiving end of the data can determine the modulation level used in the next scheduling according to the received signal including the channel fading through a fixed threshold algorithm. For details, see Figure 2. Figure 2 This is a schematic flowchart of a fixed threshold algorithm provided by an embodiment of the present application. As shown in Figure 2, the vector signal-to-noise ratio corresponding to each channel quality indicator can be obtained through the training sequence and offline simulation. The receiver performs channel estimation according to channel fading and noise, and maps the vector signal-to-noise ratio to a scalar effective signal-to-noise ratio. The value of the mapped channel quality indication is determined by searching a preset threshold table, and is fed back to the originating end in the next channel quality indication feedback cycle, and the originating end confirms the modulation level used for the next scheduling. That is, the transmitting end selects the modulation and coding strategy according to the channel state information fed back from the receiving end, and selects the corresponding transmission rate, modulation level and modulation order from a fixed set of modulation and coding methods, so as to group the data according to the modulation level. Coding and modulation are performed to ensure that the channel can be fully utilized when data transmission occurs in the case of channel fading, and the throughput of data transmission can be improved. Therefore, determining the modulation order is particularly important for the output of data in the channel.
在调制等级对数据传输的信道进行编码与调制时，需要确定调制阶数，现有技术中，将上一次数据传输时确定的调制阶数与固定的步进值的和，确定为当前数据传输的调制阶数，并根据当前的调制阶数对信道进行调制，使得数据能够顺利传输。When the modulation level encodes and modulates the channel for data transmission, the modulation order needs to be determined. In the prior art, the sum of the modulation order determined in the last data transmission and the fixed step value is determined as the current data transmission. and modulate the channel according to the current modulation order, so that the data can be transmitted smoothly.
但是，在根据上一次数据传输时确定的调制阶数和固定的步进值确定当前数据传输的调制阶数时，由于前后两次数据传输的调制阶数之间的步进值可能不相同，因此，通过固定的步进值确定的当前数据传输的调制阶数时，使得确定的调制阶数的精度较低，使得在根据当前的调制阶数对信道进行调制时，无法准确的对信道进行调制，从而降低了信道的有效利用率。However, when the modulation order of the current data transmission is determined according to the modulation order determined in the last data transmission and the fixed step value, the step value between the modulation orders of the two data transmissions before and after the data transmission may be different. Therefore, when the modulation order of the current data transmission is determined by the fixed step value, the accuracy of the determined modulation order is low, so that when the channel is modulated according to the current modulation order, the channel cannot be accurately modulated. modulation, thereby reducing the effective utilization of the channel.
为了解决因通过固定的步进值确定的当前数据传输的调制阶数的准确性较低，而导致信道的有效利用率低的问题，可以根据与反应并跟踪信道变化情况速度相关的信号调度周期以及终端设备的移动速度，确定调制阶数的步进值的调整系数，并根据步进值调整系数确定当前数据传输的调制阶数，使得确定的调制阶数的准确性更高，能够准确的进行信道调制，从而提高了信道的有效利用率。In order to solve the problem that the effective utilization rate of the channel is low due to the low accuracy of the modulation order of the current data transmission determined by the fixed step value, the signal scheduling period can be based on the speed of responding and tracking the channel change. and the moving speed of the terminal equipment, determine the adjustment coefficient of the step value of the modulation order, and determine the modulation order of the current data transmission according to the adjustment coefficient of the step value, so that the accuracy of the determined modulation order is higher and can be accurately Channel modulation is performed, thereby improving the effective utilization of the channel.
下面，将通过具体的实施例对本申请提供的信道调制方法进行详细地说明。可以理解的是，下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。Hereinafter, the channel modulation method provided by the present application will be described in detail through specific embodiments.
