5G NR Radio Network Temporary Identifier (RNTI)
RNTI stands for Radio Network Temporary Identifier. RNTIs are used to differentiate/identify a connected UE in the cell, a specific radio channel, a group of UEs in case of paging, […]
5G Self Backhaul- Integrated Access and Backhaul
Self-Backhauling Concept Self-backhauling defined as when the access i.e. Base station – Mobile and the backhaul (Base Station to Base Station or Base Station to Core Network) share the same […]
mSAP: New PCB Technology to be used in 5G Smartphone
The light, small and multi-functional electronic products have led to the development of the printed circuit board on which the lines and vias depend on the high density interconnection (HDI), […]
Narrow Band-Physical Broadcast Channel (NPBCH)
NPBCH stands for narrow band physical broadcast channel similar to PBCH in LTE Technology. The NPBCH is used to deliver the NB-IoT Master Information Block (MIB), which provides essential information […]
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 […]
5G NR Bandwidth Part (BWP)
A Bandwidth Part is a contiguous set of physical resource blocks (PRBs) on a given carrier. These RBs are selected from a contiguous subset of the common resource blocks for […]
5G NR Reference Signals (DMRS, PTRS,SRS and CSI-RS)
To increase protocol efficiency, and to keep transmissions contained within a slot or beam without having to depend on other slots and beams, NR introduces the following four main reference […]
5G Cell Phone Architecture
5G cell phones has to be designed to comply either 3GPP New Radio (NR) Release 15 and also need to support legacy radio access technologies . Intial, 5G cell phones […]
Amplifier Efficiency Concept, How Envelope Tracking (ET) helps better efficiency to Power Amplifiers?
Envelope tracking (ET) describes an approach to radio frequency (RF) amplifier design in which the power supply voltage applied to the RF power amplifier is continuously adjusted to ensure that the amplifier is operating at peak efficiency for […]
NB-IoT Frequency Bands (As per 3GPP Rel. 13, 14 and 15)
3GPP has defined a set of frequency bands for which NB-IoT can be used. 3GPP TS 36.101 from Release 13 provides the list of the supported bands: 1, 2, 3, 5, […]
