通信设备支持的最大数据传输带宽的信息，可以包括如下几种信息：
(一)通信设备支持的最大数据传输带宽值的信息
可以采用协议中规定的有限的比特(bit)表示通信设备支持的最大数据传输带宽值的信息。协议可以规定采用n个比特来传递通信设备支持的最大数据传输带宽的信息。n为正整数。例如，以20MHz带宽，15kHz子载波间隔，6.7％CP开销的参数为例，如果协议规定采用两比特来传递通信设备支持的最大数据传输带宽的信息，通信设备支持的最大数据传输带宽值可以为四个值，比如：18MHz，18.72MHz，19.44MHz和19.44MHz。用00表示通信设备支持的最大数据传输带宽为18MHz，01表示通信设备支持的最大数据传输带宽为18.72MHz，10表示通信设备支持的最大数据传输带宽为19.44MHz，11表示通信设备支持的最大数据传输带宽为19.98MHz。如果协议规定采用一比特来传递通信设备支持的最大数据传输带宽的信息，支持的最大数据传输带宽值可以为两个值，比如18MHz和18.72MHz。0表示通信设备支持的最大数据传输带宽为18.72MHz，1表示通信设备支持的最大数据传输带宽为19.44MHz。协议也可以规定采用其他比特数来传递通信设备支持的最大数据传输带宽的信息。比如3bits。
可选的，如果预先设置最大数据传输带宽的值和索引(index)的对应关系，通信设备支持的最大数据传输带宽的信息为通信设备支持的最大数据传输带宽对应的索引信息。通知通信设备支持的最大数据传输带宽包括，通知通信设备支持的最大数据传输带宽对应的索引信息。例如，预先设置最大数据传输带宽的值和索引(index)的对应关系的表格如下：

(三)通信设备支持的最大数据传输带宽所对应的资源块(英文：resource block；简称：RB)数量的信息
如果子载波间隔和RB数量是确定，数据传输带宽就是确定的。可以根据子载波间隔和通信设备支持的最大数据传输带宽所对应的RB数量确定通信设备支持的最大数据传输带宽。通常认为一个RB包含L个符号与K个子载波，其中L和K均为大于1的正整数。通信设备支持的最大数据传输带宽的值为通信设备支持的最大数据传输带宽所对应的RB数量，和一个RB中包含的子载波的个数，以及子载波间隔的乘积。可以采用协议中规定的有限的比特(bit)表示通信设备支持的最大数据传输带宽所对应的RB数量的信息。协议可以规定采用n个比特来传递通信设备支持的最大数据传输带宽所对应的RB数量的信息。n为正整数。例如，以20MHz带宽，15kHz子载波间隔，6.7％CP开销的参数为例，假设通信设备支持的最大数据传输带宽所对应的RB数量范围为100个RB到110个RB。如果协议规定采用两比特来传递通信设备支持的最大数据传输带宽所对应的RB数量的信息，通信设备支持的最大数据传输带宽所对应的RB数量可以为四个值，比如：110，104，97和99。比如：00表示通信设备支持的最大数据传输带宽所对应的RB数量为110个RB,01表示通信设备支持的最大数据传输带宽所对应的 RB数量为104个RB(104个RB对应于20MHz载波带宽上的18.72MHz数据传输带宽)，10表示通信设备支持的最大数据传输带宽所对应的RB数量为97个RB(97个RB对应于20MHz载波带宽上的19.44MHz数据传输带宽)，11表示通信设备支持的最大数据传输带宽所对应的RB数量为99个RB(99个RB对应于20MHz载波带宽上的19.98MHz数据传输带宽)。如果协议规定采用一比特来传递通信设备支持的最大数据传输带宽所对应的RB数量信息，通信设备支持的最大数据传输带宽所对应的RB数量的值可以为两个值，比如110和104。0表示通信设备支持的最大数据传输带宽所对应的RB数量为104个RB，1表示通信设备支持的最大数据传输带宽所对应的RB数量为104个RB。协议也可以规定采用其他比特数来传递通信设备支持的最大数据传输带宽所对应的RB数量的信息。比如3bits。
