To improve the capacity of cellular systems without additional expenses on licensed frequency bands, the 3GPP consortium has designed cellular technologies that use the unlicensed spectrum. The important peculiarity of the usage models of these technologies, the latest of which is New Radio Unlicensed (NR-U), is the coexistence with Wi-Fi networks deployed in the same ...

New Radio-Unlicensed (NR-U) is a technology that allows fifth generation mobile networks to utilize unlicensed frequency bands, in particular, the 5 GHz band. To increase throughput, an NR-U base station (gNB) can simultaneously operate in several frequency channels within the 5 GHz band. However, the gNB cannot always transmit data through one channel and, at ...

To achieve higher throughputs in cellular networks, 3GPP proposes to use unlicensed frequency bands and develops technologies - the latest one is NR-U - allowing a cellular base station to transmit in unlicensed bands, which are already occupied by Wi-Fi networks. To enable fair channel sharing between two technologies, the base station uses a sort ...

The volume of traffic transmitted over cellular networks is growing significantly every year. To improve LTE network throughput, 3GPP has proposed License-Assisted Access (LTE-LAA), which allows utilizing the unlicensed 5GHz spectrum already used by Wi-Fi and other technologies. To enable fair resource sharing, LTE-LAA adopts CSMA/CA-based channel access with binary exponential backoff similar to Wi-Fi. ...

To satisfy the increasing demands for high throughput of 5G networks, 3GPP has designed the NR-U technology allowing a cellular base station (gNB) to utilize unlicensed frequency bands. In particular, with NR-U, a gNB can operate in the 5 GHz frequency bands already used by widely deployed Wi-Fi networks.
Obviously, to achieve the best performance, a gNB ...

To improve the performance of LTE cellular networks operating in the licensed frequency spectrum, a new LTE-LAA technology has been developed that allows LTE devices to transmit data in unlicensed frequency bands already used by Wi-Fi devices. The channel access method in LTE-LAA networks, as well as in Wi-Fi networks, is based on the mechanism ...

An increase in the network capacity is a requirement for modern LTE cellular networks. A part of the RF spectrum that is available for transmission is among the most important limiting factors. Such a problem can be solved in the LTE networks using unlicensed bands that are employed in alternative (e.g., Wi-Fi) technologies with the ...

NR-U is a technology that allows fifth generation cellular networks to utilize unlicensed frequency bands, in particular, the 5 GHz band. In order to increase throughput, an NR-U base station (gNB) can operate at the same time in several frequency channels located within this band. However, a gNB can not always simultaneously transmit in one channel ...
