Telecommunication Technologies: 4G vs 5G Power Control Analysis

This presentation provides a detailed comparison between 4G and 5G telecommunication technologies, focusing on power control and link adaptation. It begins with introductions to both 4G and 5G wireless technologies, followed by an explanation of power control in wireless networks, including PUSCH power control, open-loop, closed-loop, and adaptive power control. The presentation then explores power control in both 4G and 5G networks, including interference measurement-based power control in 4G. Furthermore, it delves into link adaptation in 4G and 5G, comparing their methods and costs. The presentation concludes by summarizing the key differences in power control and link adaptation, providing insights into the performance and efficiency of each technology. This presentation is designed to offer a comprehensive understanding of the advancements and differences between 4G and 5G in terms of power management and communication optimization, supported by cited research.

TELECOMMUNICATION

COMPARISON BETWEEN 4G AND 5G
POWER CONTROL
• 4G is an effective communication technology
which is used for exchanging data.
• It is an advanced version of 3G technology that
reduces the security and speed related issues
(Wang, et al., 2013).
• But, 5G is an advanced technology which is more
reliable and effective rather than 4G. In terms of
power, 4G required more power for operating
networks but 5G needs less power.

COMPARISON BETWEEN 4G AND 5G
POWER CONTROL

COMPARISON BETWEEN 4G AND 5G
POWER CONTROL
• 4G wireless technology uses uplink functions in
power control.
• But, 5G wireless technology uses both uplink and
downlink functions in power control.
• In 4G technology, PUSCH power control helps
consumers for controlling output power.
• But, in 5G technology PUSCH help the consumer
for controlling and managing both Tx and Rx
powers (Singh, and Singh, 2012).

COMPARISON BETWEEN 4G AND 5G LINK
ADAPTATION
• The term link adaptation is a process which is
used in radio communication.
• In the 4G technology, the link adaptation is used
for reducing errors.
• But in the 5G technology, the link adaptation is
used for improving coding rate and modifying the
channels (Danneberg, et al., 2014).

COMPARISON BETWEEN 4G AND 5G LINK
ADAPTATION
4G link adaptation 5G link adaptation
It is very simple and easy to
design
More complex
It uses small numbers of
parameters
Uses large numbers of
parameters
It takes less time Require more times and efforts
Improve flexibility of networks Reduce flexibility of networks
The link adaptation depends on
receiver networks
The link adaptation depends on
the MIMO system and receiver
architecture

COMPARISON BETWEEN 4G AND 5G
LINK ADAPTATION
• In the case of 4G technology, the lower size of
link adaptation can be used.
• But, in 5G technology a large size of link
adaptation is required.
• In terms of cost, the 4G link adaptation is more
costly as compared to the 5G link adaptation.
• Moreover, link adaptation accuracy in the 4G
technology is very high but in 5G technology it is
limited (Chih-Lin, et al., 2014).
