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 […]
5G NR Interfaces X2/Xn, S1/NG, F1 and E1 Functions
In LTE networks, X2 and S1 interface are defined as an interfaces between RAN nodes and between RAN and Core Network. 5G is expect to operate in two modes as […]
5G NR Resource Block Definition and RBs Calculation
Resource Block Definition In 5G, One NR Resource Block (RB) contains 12 sub-carriers in frequency domain similar to LTE. In LTE resource block bandwidth is fixed to 180 KHz but […]
5G NR Sounding Reference Signal (NR-SRS)
In NR there are two types of Reference Signal in UL which gives information about the channel quality. DMRS:- Demodulation Reference Signal SRS:- Sounding Reference Signal With the help of […]
5G NR Signaling Radio Bearers (SRBs)
SRB stands for Signaling Radio Bearer.”Signalling Radio Bearers” (SRBs) are defined as Radio Bearers (RBs) that are used only for the transmission of RRC and NAS messages. As per 3GPP […]
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 […]
5G NR Bandwidth Part (BWP)
A Bandwidth Part (BWP) 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 […]
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 […]
