### Performance Comparison between LSTM-RRM and QOC-RRM
Here, the comparison is made by varying the threshold from 10 to 30. From the analysis, it can be seen that the LSTM-RRM with 4 BS achieves higher guaranteed capacity than the LSTM-RRM with 15 BS. For example, the guaranteed capacity of the LSTM-RRM with 4 BS varies from 550 kbps to 835 kbps, whereas the guaranteed capacity of the LSTM-RRM with 15 BS varies from 280 kbps to 600 kbps. Figure 12: Comparison of OSR. Figure 13: Comparison of guaranteed capacity. The comparison of indoor guaranteed rate between LSTM-RRM and QOC-RRM [21] is shown in Figure 14 and Table 13. Here, the indoor guaranteed rate is analyzed by varying the building distance from 400 m to 1400 m. From the analysis, it can be seen that the LSTM-RRM achieves a higher indoor guaranteed rate than the QOC-RRM [21]. For example, the LSTM-RRM achieves an indoor guaranteed rate in the range from 178 Mbps to 228 Mbps, whereas the QOC-RRM [21] achieves an indoor guaranteed rate in the range from 85 Mbps to 130 Mbps. The indoor guaranteed bitrate of LSTM-RRM for a building distance of 1400 m is improved up to 75.38% when compared to the QOC-RRM [21]. The indoor guaranteed rate of LSTM-RRM is increased by reducing the interferences occurring during the communication. Figure 15 and Table 14 show the outdoor guaranteed rate comparison between QOC-RRM [21] and LSTM-RRM. Here, the comparison is made by varying the building distance from 400 m to 1400 m. From the analysis, it can be seen that the LSTM-RRM achieves a higher outdoor guaranteed rate than the QOC-RRM [21]. For example, the outdoor guaranteed rate of the LSTM-RRM varies from 178 Mbps to 228 Mbps, whereas the outdoor guaranteed rate of the QOC-RRM [21] varies from 168 Mbps to 174 Mbps. Specifically, the outdoor guaranteed bitrate of LSTM-RRM for a building distance of 1400 m is improved up to 31.03% when compared to the QOC-RRM [21]. From the analysis, it can be concluded that the LSTM-based RRM provides better performance than the DRRM [20], QOC-RRM [21], and EPAS [30], individually. The QOS parameters of the LSTM-based RRM are high due to its optimal bandwidth and power allocation to the user equipment of the 5G network. Moreover, the LSTM provides optimal results during the RRM because of the hyperparameters identified from GSO. Here, a queue-based RRM is used to minimize the traffic during data transmission. Moreover, the ISI caused in the network is reduced via guard level insertion in the data. Hence, the sum rate and guaranteed rate are increased while transmitting the data packets under burst errors.
