The 5G standard defines multiple numerologies, each suited to specific deployment and service requirements.

Subcarrier spacing is the frequency spacing between adjacent subcarriers in an OFDM system, determining the bandwidth of each subcarrier and impacting overall bandwidth, latency, and performance.

Each subcarrier is spaced 30 kHz apart, which determines how data is divided across the available bandwidth.

The duration of each OFDM symbol is the inverse of the subcarrier spacing, which is approximately 33.3 microseconds.

To find the number of subcarriers, divide the usable bandwidth by the subcarrier spacing, resulting in 825 subcarriers.

The different numerologies in 5G are primarily characterized by their subcarrier spacing, a critical factor in defining the symbol duration and cyclic prefix length.

Numerology is a complex system that analyzes numbers to gain insight into our lives, personalities, and destinies. It's based on the idea that numbers hold the secrets to our soul's journey.

The most commonly used numbers in numerology are the Life Path Number, calculated from our birthdate, and the Destiny Number, calculated from the letters of our name. These numbers are thought to reveal our potential, challenges, and life purpose.

A Life Path Number of 1 indicates a strong sense of individuality and leadership, while a Life Path Number of 8 suggests a natural talent for business and finance.

Table 2 reveals that a person's life path number can be calculated by adding up the individual digits of their birthdate. This calculation can provide insight into a person's personality, strengths, and challenges.

The life path number is often seen as a blueprint for a person's life journey, influencing their experiences and opportunities. A life path number of 1 is associated with leadership qualities, independence, and a strong sense of self.

Individuals with a life path number of 2 tend to value harmony and balance, often prioritizing relationships and cooperation. They're known for their diplomacy and ability to mediate conflicts.

A life path number of 3 is associated with creativity, self-expression, and a love of communication. People with this number are often charismatic and enjoy being the center of attention.

Indexes are like shortcuts in numerology, allowing us to quickly find specific numbers and their meanings. They're a key part of understanding the deeper significance of numbers.

The Master Numbers 11, 22, and 33 are considered indexes because they hold powerful energies and significance. They're often associated with spiritual growth and higher consciousness.

In numerology, the Life Path Number is an index that reveals our life's journey and purpose. It's calculated by adding up the digits of our birthdate and reducing them to a single number.

The Expression Number, also known as the Destiny Number, is another index that shows our potential and life's purpose. It's calculated by assigning numerical values to the letters in our name and reducing them to a single number.

Antagonistic DRBs and numerologies can be a challenge to manage, but understanding their relationships can help. The most antagonistic DRBs are video conferencing and Pre-AR/VR, followed by VoIP, buffered streaming, real-time gaming, and live streaming.

As the granularity of the profiles, k, increases, the most antagonistic DRBs shift. For k=2, the most antagonistic DRBs are video conferencing and Pre-AR/VR, while for k=3, they are video conferencing, VoIP, buffered streaming, real-time gaming, and live streaming.

The best numerology indexes for these applications vary depending on k. For k=2, Numerology Index 2 with extended CP (2eCP) and 4 are the best choices. For k=3, Numerology Index 0, 2eCP, and 4 are the best options.

Here's a breakdown of the best numerology indexes for each application:

In conclusion, understanding the relationships between DRBs and numerologies is crucial for optimizing wireless communication scenarios.

The satisfaction of QoS requirements is a key performance metric in wireless numerology. The average satisfaction of user/application requirements can be significantly improved by applying a mathematical optimization approach.

The optimization approach chooses adequate numerology indexes, resulting in average satisfaction ranges of [0.6-1] for the "optimized" approach compared to [0.4-0.65] for the "non-optimized" approach.

This improvement in satisfaction level can be substantial, with the "optimized" approach potentially doubling the satisfaction of the "non-optimized" one, depending on the profile.

Spectral efficiency is directly related to the amount of spectrum allocated to numerology index 2eCP.

The greater the amount of spectrum allocated to numerology index 2eCP, the lower the spectral efficiency is, as expected.

Fair spectrum allocation among the numerology indexes is guaranteed, ensuring equal quality of experience for the different users/services.

Satisfaction of QoS Requirements is a crucial aspect of any network performance. The average satisfaction of user/application requirements can be measured and compared.

The plots in Figure 5 show the average satisfaction of user/application requirements, with the "optimized" bar indicating the best possible outcome. This is achieved by applying a mathematical optimization approach to the numerology index.

The "optimized" bar ranges from 0.6 to 1, indicating a high level of satisfaction. In contrast, the "non-optimized" bar ranges from 0.4 to 0.65, showing a lower level of satisfaction.

The optimization approach is able to choose adequate numerology indexes, leading to improved satisfaction levels. This is especially true when considering multiple antagonistic DRBs, as the satisfaction level can be twice as much as the non-optimized approach.

For k=6, the mixed numerology includes all required numerology indexes, resulting in 100% satisfaction. This highlights the effectiveness of the optimization approach in meeting user/service requirements.

In 5G, the term "numerology" refers to the various configurations of subcarrier spacing and other parameters that are designed to meet different performance and deployment requirements.

The subcarrier spacing is the frequency spacing between adjacent subcarriers in an orthogonal frequency-division multiplexing (OFDM) system.

It determines the bandwidth of each subcarrier and impacts the overall bandwidth, latency, and performance of the wireless system.

Each subcarrier is spaced 30 kHz apart, which determines how data is divided across the available bandwidth.

To find the number of subcarriers, you can divide the usable bandwidth by the subcarrier spacing.

The duration of each OFDM symbol is the inverse of the subcarrier spacing, which is approximately 33.3 microseconds.

The 5G standard defines multiple numerologies, each suited to specific deployment and service requirements.

Cell edge users are scheduled as inner users of the subblocks with suitable numerologies to protect them from INI effects.

Power level (PL) and bandwidth (BW) of a UE are considered as the two main inputs for the proposed PDB scheduling methods.

The proposed algorithms focus only on candidate edge UEs, and after the decision of edge users, the other outer UEs can be scheduled flexibly in the frequency domain.

Scheduling flexibility does not lose, and the main aim of our scheduling algorithms is to minimize the variance between SIR values for different cases.

Random scheduling results in too much fluctuation in SIR at the edge UEs of different numerologies.

Proposed algorithms balance SIR to preserve the fairness between users, and the amount of INI is taken into account with channel conditions for the PF scheduling to balance fairness regarding INI.

CDF curves are used to show the statistical results of all methods, and the proposed algorithms are compared with random scheduling and PF scheduling cases.

GB usage scenarios are included with the algorithm results, and the overall reliability is also enhanced by our novel scheduling methods.
