NR Sound 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 […]
Multi Carrier Cell Re-selection in LTE
Cell Re selection is a procedure used to change the cell after the UE is camped on a cell and stays in the Idle mode.This procedure is used to let […]
5G NR BWP Types and BWP Operations
In 5G New Radio the cell bandwidth is expected to be large compared to LTE, but a UE’s receive and transmit bandwidth is not necessarily required to be same as […]
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 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 […]
5G-NR (New Radio) Modem Chipset Vendors
5G New Radio development is going at fast pace and its network rollout sounds good in very near future. These networks will not be useful without devices and devices will […]
5G NR-Master Information Block (NR-MIB)
Over all structure of MIB and SIB in NR is almost similar to LTE and other legacy technologies. However there is a major difference related to the periodical transmission of […]
