Udc uplink data compression

  • What is the process of data compression?

    Data compression is the process of encoding, restructuring or otherwise modifying data in order to reduce its size.
    Fundamentally, it involves re-encoding information using fewer bits than the original representation..

  • What is UDC in data compression?

    Uniquely Decodable Codes (UDC) • Uniquely Decodable code is nothing but that is there should be only. one way of interpreting the sequences with their associated. codewords..

  • Robust header compression (RoHC) for PDCP PDU payload size reduction.
    The initial version is called ROHC v1 and based on RFC 3095 and RFC 4815 (with clarifications in RFC 3759).
Jun 3, 2018A UDC data block contains either DEFLATE compressed blocks generated by UDC protocol or original PDCP SDU for SDU not compressed by UDC; the 
Uplink data compression is a potential technique that can enhance uplink transmission efficiency in wireless communication systems. It offers benefits such as reduced transmission time, improved bandwidth efficiency, and reduced network load.

How does compression affect a website?

Since compression reduces the amount of data sent in the uplink, the HTTP requests are received and processed sooner by the webserver.
Thus, the webpage loads faster.
This benefit increases as the uplink data rate becomes more restricted (smaller), e.g. in conditions of lower power headroom and/or uplink grant.

How does uplink interference affect network performance?

From a network point of view the reduction in uplink interference improves capacity and data rates for all UEs, including:

  1. legacy ones

Alternatively, one can think of compression enabling the UE to send more data for a given bandwidth, hence improving the perceived speed of connection.

What is data compression?

One of which is the data compression feature

Compressing the uplink data between a UE and the EPS (Evolved Packet System) can provide gains for user throughput, latencies and capacity by performing such compression for HTTP traffic

This whitepaper discusses the techniques of doing data compression

Uplink data compression (UDC) is a method of improving uplink capacity by compressing uplink (UL) data. For UDC, many compression algorithms can be applied. For example, two different UDC compression algorithms described in RFC1951 DEFLATE and RFC1950 ZLIB. UDC uses a dictionary-based compression method.
