Understanding the 5G NR Physical Layer - Keysight.
This paper will outline the benefits of a packet-based fronthaul technology to the business case for 5G NR virtualized RANs, and describe Comcores’ demonstrator. This provides detailed measurements based on four important enablers of the new RAN architecture - 5G NR; 100 MHz channels; IEEE 1914.3 RoE encapsulation and mapping; and functional splits which offload some of the baseband.

In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes a timing value indicating a timing of an opportunity, subsequent to reception of the DCI, for transmission or reception of a communication corresponding to the DCI. The UE may determine an uplink opportunity or a downlink opportunity for transmission or reception of the communication based at.

Designing for the future: the 5G NR physical layer Future networks will have to provide broadband access wherever needed and support a diverse range of services including everything from robotic surgery to virtual reality classrooms and self-driving cars. 5G New Radio is designed to fit these requirements, with physical layer components that are flexible, ultra-lean and forward-compatible.

According to the NR definition of TTI, one TTI duration corresponds to a number of consecutive OFDM symbols in the time domain in one transmission direction, and different TTI durations can be defined when using different number of OFDM symbols (e.g., corresponding to a mini-slot, one slot or several slots in one transmission direction). We define a slot as a period of time containing 14 OFDM.

NR can also employ mini-slots to support transmissions with a flexible start position and a duration shorter than a regular slot duration. In principle, a mini-slot can be as short as one OFDM symbol and can start at any time. In Release 15, mini-slots are limited to 2, 4, and 7 OFDM symbols. Mini-slots can be useful in various scenarios, including low-latency transmissions, transmissions in.

But 5G has other options, including 30 kHz subcarrier with a 500 microsecond slot plus the option for a “mini-slot,” 60 kHz with a 250 microsecond slot, and 120 kHz with a 125 microsecond slot. The 120 kHz option enables very efficient millimeter wave communications. By way of contrast, the 30 kHz option will be predominant in mid-band time division duplex (TDD) spectrum between 3 MHz and.
