5G NR Cell Access Control

Radio Access barring control refers to a traffic congestion control mechanism to secure and ensure the success of critical communications calls such as emergency calls by restricting connection requests from […]

5G NR Network Relationship – Neighbor Planning

In any telecommunication technology starting from 2G to 5G, Neighbor relation or to say Neighbor planning is an important activity. Neighbor relation information is very critical for cell re-selection while […]

5G NR User Plane Latency

The definition of user plane latency as per 3GPP TR 38.913, is  “the time to successfully deliver an application layer packet/message from the radio protocol L2/L3 SDU entering point to […]

What parameters impact the EVM of transmitter chain ?

The error vector magnitude or EVM is a measure used to quantify the performance of a digital radio transmitter or receiver. A signal sent by an ideal transmitter or received by a receiver would have all constellation […]

Robust Header Compression – ROHC

ROHC is a header compression protocol/algorithm that can be used compress the header of different IP packets. In normal case without compression  IPv4 header is 40 bytes and IPv6 header […]

TTI Bundling for better HARQ and Latency

TTI bundling enables a data block to be transmitted in consecutive TTIs, which are packed together and treated as the same resource during the scheduling process. TTI bundling makes use […]

PLMN Selection in LTE (Idle Mode Action)

UEs can be either in RRC_CONNECTED or RRC_IDLE mode. UEs will be declared as RRC_IDLE if there is no RRC connection between the UEs and the eNodeB and RRC_Connected when […]
