Toward a New Era of Radio Access Technologies for Beyond 5G and 6G
In the near future, the number of devices connected to communication networks is expected to dramatically increase. To provide connectivity to this massive number of devices and to fulfill their quality of service (QoS) requirements, there is an inevitable need for new mobile communications systems with significantly enhanced capabilities. This is the primary driving force of the fifth generation and beyond (B5G)/ sixth generation (6G) wireless systems.
In the previous communication systems and existing LTE/LTE-Advanced systems, multiple access (MA) techniques such as timed division multiple access (TDMA), frequency division multiple access (FDMA), and orthogonal frequency division multiple access (OFDMA) were used. However, in recent years, researchers have moved towards breaking the orthogonality, thereby finding ways of user multiplexing over the same resource block (RB). Hence, a novel concept of non-orthogonal multiple access (NOMA) was introduced to handle the huge connectivity concerns of 5G. NOMA as a multiple access scheme and several pulse-shaping techniques have been presented by researchers to increase systems’ spectral efficiency. Further, for future communications, some state-of-the-art techniques such as index modulation need to be discovered to develop compatible systems for B5G.
This talk shall cover modern radio access technologies (RATs) that have the potential to make their place in the next generation networks.
