Base station downlink communication mode

4 FAQs about [Base station downlink communication mode]

What is downlink & uplink transmission?

Downlink and uplink transmission refers to the communication channels in cellular networks where downlink is the transmission from base stations to mobile users, and uplink is from mobile users back to base stations. These channels experience various degradations such as path loss, shadowing, and small-scale fading, affecting their performance.

What is Nr-DL transmission mode?

In 5G (fifth-generation) wireless communication systems, NR-DL Transmission Mode refers to the Downlink Transmission Mode in the New Radio (NR) standard. Transmission modes define the method and strategies for transmitting signals from the base station (gNodeB) to the user equipment (UE).

What is downlink frequency?

The frequency used for all transmissions from the Base Station to the Mobile Subscriber Unit (MS) is known as the downlink frequency. The data transmission direction from the BS to the MS is called the downlink direction.

What is the LTE downlink transmission scheme?

The LTE downlink transmission scheme is based on conventional OFDM. As discussed in Chapter 3, OFDM is an attractive transmission scheme for several reasons. Due to the relatively long OFDM symbol time in combination with a cyclic prefix, OFDM provides a high degree of robustness against channel frequency selectivity.
