Добрый вечер. Подскажите,пожалуйста, почему такие значения ОСШ? Откуда они взяты?

Кое-что нашел в интернете Required SINR is the main performance indicator for LTE. Cell edge is defined according to the Required SINR for a given cell throughput. Therefore, the accurate knowledge of Required SINR is central to the authenticity of the RLB and thus the process of dimensioning. Required SINR depends up on the following factors: • Modulation and Coding Schemes (MCS) • Propagation Channel Model

Higher the MCS used, higher the required SINR and vice versa. This means that using QPSK will have a lower required SINR than 16-QAM .

Required SINR can be estimated by two different methods. • By using the ‘Throughput vs. average SNR’ tables. These tables are obtained as an output of link level simulations. For each type of propagation channel models and different antenna configurations, different tables are needed. One important thing to note here is that noise is modelled as AWGN noise; therefore, SNR is used instead of SINR. • By using the Alpha-Shannon formula [22]. Alpha-Shannon formula provides an approximation of the link level results. Thus, in this case, no actual simulations are needed, but factors used in Alpha-Shannon formula are needed for different scenarios.

Данные значения должны быть табулированы, но очень хочется услышать ответ специалиста
