Does uplink compression reduce energy consumption?
Energy saving increases as uplink becomes more restricted.
Field data from a metropolitan area suggests that at least 10% of time the pilot power is 15dBm or higher, leading to at least 45% reduction in energy consumption for browsing.
Table 1 shows the benefit to legacy UEs from use of uplink compression by compression capable UEs.

Enhancements For Lte
The study items further enhancing the LTE-Advanced Pro include the following: Study on Uplink Data Compression (UDC): With more and more users creating content on their mobile phones and sharing it with the world by uploading/streaming, the UL traffic growth has been substantial and so far, the mobile networks have been focused mostly on increasing.

How does 3GPP improve uplink performance for LTE networks?
3GPP has developed several advanced and reliable mechanisms to improve the uplink performance for LTE networks.
The mechanism use compression methods for headers and data payload in order to reduce the overhead on the air interface when uplink data is sent.
,
How to increase uplink capacity?
Increase uplink capacity when the amount of data sent in uplink is reduced.
Increase the uplink and downlink data rates by sending less uplink data same amount of information (on downlink the benefits come from shorter TCP ACKs, needed for the same amount of downlink data).

Summary
As the target for completion of Rel-15 is September 2018, the work on most of the study items has still not been completed and there are some items on which work has not even begun yet.
In this case we will be monitoring the developments happening within the study groups and update the latest status via our blog, so Stay Connected! If you have any .

What data can be compressed on an uplink?
On the uplink most of the data is typically protocol information such as:
- IP/TCP/HTTP headers
- these are quite compressible
There are several benefits to compressing uplink data , including:.
Frequency bands for 5G New Radio, which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges.
First there is Frequency Range 1 (FR1), which includes sub-6 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to cover potential new spectrum offerings from 410 MHz to 7125 MHz.
The other is Frequency Range 2 (FR2), which includes frequency bands from 24.25 GHz to 71.0 GHz.
Frequency bands are also available for non-terrestrial networks in the sub-6 GHz range.
