一 Supported max datarate

3GPP 38.306- 4.1.2 - Supported max data rate

给出了理论上吞吐量计算公式

The approximate maximum data rate can becomputed as the maximum of the approximate data rates computed using the aboveformula for each of the supported band or band combinations.

For EUTRA in case of MR-DC, the approximatedata rate for a given number of aggregated carriers in a band or bandcombination is computed as follows.

二 参数含义

主要有9个参数，这里面逐步解释参数的含义

2.1 J

is the number of aggregated component carriers in a band or band combination

载波聚合的数量

2.2

固定值,速率匹配

For thej-th CC（单独载波计算方式）

2.3

is the maximum numberof layers

这个可以在DCI,或者PDSCH,PUSCH 里面看到

如果是2*2 MIMO 则为2 ， 4*4MIMO 为4.

2.4

调制方式

: is themaximum modulation order

2.5

scaling factor

比例因子

: The scaling factor can take the values 1, 0.8, 0.75, and 0.4

is signalled per band and per band per band combination2.

2.6 u

is the numerology

defined in TS 38.211 [6]

Multiple OFDM numerologies are supported asgiven by Table 4.2-1 where μ and the cyclic prefix for a bandwidth part areobtained from the higher-layer parameter subcarrierSpacing and cyclicPrefix, respectively.

2.7

最小采样周期

is the average OFDM symbol duration in asubframe for numerology

u 越大该值越小

2.8

由u和BW配置对应的PRB大小

2.9

is the overhead and takes the following values

根据当前的频点以及上下行决定的

0.14, for frequency range FR1 for DL

0.18, for frequency range FR2 for DL

0.08, for frequency range FR1 for UL

0.10, for frequency range FR2 for UL
