How many prbs for 20 mhz in 5g

Introduction

The advent of 5G technology has brought about a paradigm shift in how we experience connectivity. One of the key components that makes 5G a technological marvel is the efficient use of physical resource blocks (PRBs). In this article, we’ll delve into the intricacies of PRBs in 5G, understanding their role, calculating a 20 MHz bandwidth, and the factors influencing their allocation.

Understanding PRBs in 5G

Definition and Role of PRBs

Physical Resource Blocks, commonly known as PRBs, are the fundamental units in the time-frequency domain of 5G communication. They play a crucial role in allocating spectrum efficiently, enabling seamless data transmission and reception.

What are PRBs?

Imagine a 5G channel as a bustling highway. PRBs are like individual lanes on that highway, each carrying a specific chunk of data. The more lanes (PRBs) available, the more data can flow simultaneously, leading to higher speeds.

Calculating PRBs for 20 MHz:

The number of PRBs in a 5G channel depends on two key factors:

• Carrier frequency: This is the specific radio frequency used for transmission, measured in megahertz (MHz). In our case, it’s 20 MHz.
• Subcarrier spacing (SCS): This defines the spacing between individual subcarriers within the carrier frequency. Common SCS values for 5G are 15 kHz, 30 kHz, and 60 kHz.

Now, the magic formula:

Number of PRBs = Carrier frequency (MHz) * 1000 kHz / Subcarrier spacing (kHz)

Plugging in our values for 20 MHz and, let’s say, 30 kHz SCS:

Number of PRBs = 20 MHz * 1000 kHz / 30 kHz = 666.67

However, due to guard bands and other technical considerations, the actual number of usable PRBs is slightly less. Rounding down to the nearest whole number, we get:

Number of usable PRBs for 20 MHz with 30 kHz SCS ≈ 666

Remember, this is just an example. The actual number of usable PRBs can vary depending on the specific 5G implementation and chosen

Significance of PRBs in Spectrum Allocation

In the dynamic world of 5G, spectrum allocation is a critical consideration. PRBs serve as the building blocks for this allocation, ensuring that the available spectrum is utilized optimally for high-speed and low-latency communication.
