具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在一些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本申请的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及第五代移动通信技术(The 5th Generation Mobile Communication Technology，5G)系统等，本申请实施例并不限定。在本申请中以5G系统为例进行说明。
本申请实施例可以用于不同的制式的无线网络。无线接入网络在不同的系 统中可包括不同的通信节点。图1为本申请提供的一种无线网络系统的结构示意图。如图1所示，该无线网络系统100包括基站101、用户设备110、用户设备120和用户设备130。基站101分别与用户设备110、用户设备120和用户设备130之间进行无线通信。
本申请实施例中，基站可以是能和用户终端进行通信的设备。基站可以是任意一种具有无线收发功能的设备。包括：基站(NodeB，NB)、演进型基站(evolved NodeB，eNodeB)、5G通信系统中的基站、未来通信系统中的基站、无线保真(Wireless Fidelity，WiFi)系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器；基站还可以是小站，传输参考节点(Transmission Reference Point，TRP)等，本申请实施例并不限定。
本申请实施例中，本申请实施例中，用户终端是一种具有无线收发功能的设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述用户终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。用户终端有时也可以称为终端、接入终端、用户设备(User Equipment，UE)单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。本申请实施例并不限定。
当基站利用多个子带发送数据时，各个子带的信道状态是不一样的。对于信噪比高的子带，有利于数据传输，在该子带上适合配置较高的调制编码方案(Modulation and Coding Scheme，MCS)；对于信噪比低的子带，不利于高速率的数据传输，在该子带上适合配置较低的调制编码方案MCS。
在相关技术中，当基站利用多个子带发送一个数据传输块时，不管各个子带的信道状态是否相同，该数据传输块只能整体配置一个调制编码方案，导致各子带的资源利用不够充分，限制了数据传输效率。例如，基站为一个数据传输块整体配置了一个较低的调制编码方案，但是，其中有一些子带信道状态很好，适合传输高阶调制和高码率的数据，如果在这些子带上配置高调制编码方案，则能够提高数据传输效率。
