Uplink Synchronization : This is the process in which UE figure out the exact timing when it should send uplink data (i.e, PUSCH / PUCCH). Usually a network (gNB) is handling multiple UEs and the network has to ensure that the uplink signal from every UE should be aligned with a common receiver timer of the network.
Read moreWhat is PSS and SSS in 5G?
PSS stands for Primary Synchronization Signal, SSS stands for Secondary Synchronization Signal and ESS stands for Extended Synchronization Signal. Radio frame in 5G-TF is 10ms in duration. It has total 100 slots or 50 subframes. Each subframe consists of two consecutive slots.
Read moreWhat is synchronization signal?
Transmission of a synchronizing signal along with the message signal is an approach in which the transmitter simultaneously sends a clock pilot at a multiple of symbol rate along with the information data, and the receiver then employs a very narrow BPF tuned to the clock frequency.
Read moreWhat is primary synchronization signal?
Primary synchronization signals consist of one of three 62-symbol Zadoff-chu sequences in a cell . The Primary Synchronization Signal (PSS) is broadcast twice during every radio frame and both transmissions are identical.
Read moreWhat is cell search in 5G?
Cell search is the procedure by which a UE acquires time and frequency synchronization with a cell and decode the Cell ID of that cell . In 5G NR, Cell search concept is similar to what it is in LTE in terms of decoding Primary Sync Signal (PSS) and Secondary Sync Signal (SSS) to the Physical Cell ID (PCI).28 Tem 2019
Read moreWhat is cell search in LTE?
Cell searching is a procedure in which a UE achieves time and frequency synchronization with a cell, obtains the physical cell identifier (PCI), and learns the signal quality and other information about the cell based on the PCI. A UE performs cell search on all frequencies before selecting or re-selecting to a cell.
Read moreWhat is purpose of SSS in 5G?
Cell search is the procedure for a UE to acquire time and frequency synchronization with a cell and to detect Physical layer Cell ID (PCI) of the cell .
