Case studies

Dynamic Carrier Aggregation



Challenge


Dynamic Carrier Aggregation (CA) is a key mechanism used to increase user and system throughput. Aggregation of licensed and unlicensed bands provides a means of increasing available bandwidth in 5G networks.


Solution


ICS telecom EV supports carrier aggregation for both FDD and TDD modes. The modeling of the network is composed of several layers (for example, a mix of stations operating in the 2600 MHz with 20 MHz bandwidth and 1800 MHz with 10 MHz bandwidth and so on) in the same project. Aggregated throughputs are calculated by summing the volume of data from each serving cell included in carrier aggregation. This engine enables to the user to perform a global analysis of the throughput (comparison, sum, overlapping, etc.) between the different layers.


ATDI: Everything 5G  



Air interfaces based on mmWaves coexistence with LTE networks



Challenge


Air interfaces based on mmWaves coexist with existing LTE networks in carrier aggregation mode. Future 5G network deployment scenarios will facilitate high data rates over short distances.


Solution


At high frequencies, coverage planning techniques will be radically different from those used today. Diffraction losses become so high that there is an almost binary switch between ‘served’ and ‘unserved’ areas as shadowing by environmental clutter interrupts the line-of-sight between base station and user. Using generic propagation models, mmWave stations can be computed at the same time as VHF/UHF and SHF stations in ICS telecom EV.


ATDI: Implementing new planning techniques



High-band 5G New Radio (NR)



Challenge


In 5G, New Radio (NR) cells act as the slave to LTE eNB. In non-standalone mode, the connection will be anchored in LTE-mode, while 5G NR carriers are used to boost data-rates and reduce latency. Signalization and user-traffic will be distributed in different frequency bands.


Solution


ICS telecom EV features a ‘prospective planning’ function which identifies the best locations for master low-band LTE sites. This function is based on coverage target assumptions for signaling capabilities. The ‘parenting LTE’ function is based on a population of LTE users (with profiles and traffic demands defined). This feature resolves the issue of traffic network congestion (or low traffic QoS performance) by adding new high- band 5G New Radio (NR) sites in the hot spot area to boost data-rates and reduce latency. This function takes into account DL/UL coverage criterions and traffic assumption.
