3GPP Release 16 Feature List
3GPP Release 16 Introduction The initial specifications of 5G, Release 15 also called the “5G Phase 1” introduced the 5G NR technology, provided the fundamental architecture of 5G and addressed […]
5G NR UE Power Classes
As telecom is evolving to next generations and new use cases, 3GPP has added new Power Class Categories. As per the definition, UE Power Class can be defines as the […]
5G NR RLC – AM Mode Data Transmission
In 5G NR, RLC has 3 different modes of operations TM, UM and AM and each of the mode can transmit and receive data, serving different logical channels as per […]
5G NR Layer 2 – Radio Link Control (RLC) Overview
5G RLC overall functionality is almost same as LTE RLC. In 5G also, RLC has 3 different modes of operations and each of the mode can transmit and receive data, […]
3GPP Evolution for MIMO
Released 3GPP standards on MIMO are shown in below image. As you know, Coordinated Multipoint (CoMP) is a type of Cooperative MIMO, in which data and channel state information (CSI) are […]
What is the difference between co-located BTS and co-existed BTS and explain the required 3GPP compliance
Co-existence with other systems The manufacturer shall declare whether the BS under test is intended to operate in geographic areas where one or more of the systems GSM850, GSM900, DCS1800, […]
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 […]
What is LTE-LAA and its co-existence with other technologies
Licensed-assisted access (LAA) is a 3GPP enhancement of Long-Term Evolution (LTE) to allow cellular network operators to offload some of their data traffic by accessing the unlicensed 5 GHz frequency […]
3GPP Release-15 UE Cat Types, Throughput, Modulation and DL / UL Combinations
UE Category information is used to allow the eNB to communicate effectively with all the UEs connected to it. The ue-Category defines a combined uplink performance capability and downlink performance capability. […]
3GPP Release 12
3 GPP Release 12 was largely completed on-time in March 2015, with a few exceptional features allowed an extension to later in the year. Release 12 builds on the innovations in […]
