5g numerology table
5G (fifth-generation) cellular networks, the numerology table is an essential concept that helps define various parameters for the design and deployment of the system. The numerology table provides the framework for different aspects of the 5G waveform, including subcarrier spacing, symbol duration, and slot duration. Let's break down the 5G numerology table technically in detail:
- Subcarrier Spacing (Δf):
- The 5G numerology defines various subcarrier spacings, denoted by Δf. Common values for 5G include 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz. The choice of subcarrier spacing depends on the specific use case and deployment scenario.
- Smaller subcarrier spacings allow for higher data rates but may require more complex receiver processing. Conversely, larger subcarrier spacings are more robust against delay spread and Doppler effects but may offer lower peak data rates.
- Symbol Duration (T_s):
- Symbol duration is the time taken to transmit one symbol in the 5G waveform. It is inversely proportional to the subcarrier spacing. Mathematically, T_s = 1/Δf.
- For instance, if the subcarrier spacing Δf is 15 kHz, the symbol duration T_s would be approximately 66.7 μs (microseconds).
- Slot Duration:
- A slot in 5G represents a time duration that includes multiple symbols. The slot duration is typically defined based on the symbol duration and the number of symbols per slot.
- The 5G numerology table can define different slot durations based on the configuration, but a common choice might be several symbols per slot, with each symbol having a duration of T_s.
- Number of Subcarriers per Slot (N_SC):
- The 5G numerology table also specifies the number of subcarriers that can be accommodated within a single slot. The number of subcarriers per slot is determined based on the subcarrier spacing Δf and the slot duration.
- Mathematically, ���=������������Δ�NSC=Δfslotduration.
- Symbol Periodicity:
- The 5G numerology table defines the periodicity of symbols and slots to enable efficient transmission and reception. Symbol periodicity ensures that devices can synchronize and decode the transmitted signals correctly.
- Depending on the deployment scenario and requirements, the symbol and slot periodicities can be adjusted.In the context of 5G (fifth-generation) cellular networks, the numerology table is an essential concept that helps define various parameters for the design and deployment of the system.
