Thanks for the great content. Simple to understand the operation of LTE and 5G NR.
Very good explanation.
Thanks Leo
Great explanation Leonardo… Thanks
Why the 10% guard band concept does not apply in 1.4 Mhz bandwidth?
Really Very helpfully
Amazing article!!!
The way you explained this made me save plenty of time to look up several answers for my questions. Thank you so much looking forward for your next articles.
This is an incredible blog on LTE radio physical resources. The illustrations are unmistakably detailed making each point visually clear.
THANK YOU!
Thanks indeed
Very informative. Many thanks Dear
Very good explanation. But I still have some confusions. Since one scheduling block is the smallest block to give to a user, which consists of two time-adjacent PRBs, why we say the RB is the smallest unit of resources that can be allocated to a user. These two statements seem conflicting. If we say the PRB is not allocated alone but in pair, then what’s the meaning of defining a single PRB with a time duration of 0.5s? Looking forward to your answer. Thanks!
Thank you very much
HI
Please clarify this on the Antenna port and the relationship between RB and the Antenna port
thank you very much
Here is also a nice article explaining PRB:
Understanding LTE’s Physical Resource Block (PRB)
LTE is a widely used cellular technology that provides high-speed data services to mobile devices. One of the key components of LTE is the physical resource block (PRB). In this article, we will explore the basics of PRBs, their characteristics, and their importance in the LTE network.
Thank you so much for your time, knowledge and effort. The contents are well explained, organized and illustrated. Best explanation so far.
5G Resource Block (RB) and Resource Element (RE) Concept :
5G Resource Block (RB) and Resource Element (RE) are essential components in the 5G radio frame structure for efficient utilization of radio resources
5G Resource Block (RB): A resource block (RB) is the smallest unit of radio resources allocated to a user or device in the time-frequency domain. It is used to transmit and receive data, such as control and user information, within a 5G network.
RB Size: In 5G, an RB consists of 12 contiguous subcarriers in the frequency domain and a specific number of OFDM (Orthogonal Frequency Division Multiplexing) symbols in the time domain. The time duration of an RB depends on the subcarrier spacing and the number of OFDM symbols.
RB Allocation: The allocation of RBs to users is based on their needs and network conditions. The 5G scheduler is responsible for assigning RBs efficiently to ensure high network performance and minimize interference.
5G Resource Element (RE): A resource element (RE) is the smallest unit within a resource block. It represents a single subcarrier in the frequency domain and a single OFDM symbol in the time domain.
RE Building Blocks: Each resource block (RB) contains multiple resource elements (REs). For example, if an RB has 12 subcarriers and 14 OFDM symbols, it consists of 12 x 14 = 168 REs.
RE Usage: Resource elements are used for various purposes, such as transmitting control information (e.g., synchronization signals, channel state information) and user data (e.g., voice, video, data traffic).
In summary, the 5G radio frame structure utilizes resource blocks () and resource elements () to efficiently allocate and manage radio resources for various devices and applications in a 5G network. The 5G scheduler assigns resource blocks to users, and each resource block is composed of multiple resource elements.
