Physical Cell ID is mainly used by UE to decode physical layer data being transmitted by eNodeB. Cell ID in SIB1 is designed for eNodeB management within the core network, but this one is also used for UE to identify a specific cell in terms of RRC/NAS layer processing.

What is physical cell ID in telecom?
A Physical Cell Id (PCI) is the identifier of a cell in the physical layer of the LTE net- work, which is used for separation of different transmitters. Due to the construction of PCIs, the number of PCIs are limited to 504.
What is physical cell ID in 5G?
Physical Cell ID (PCI) is one of the most important cell’s identifier in the wireless network of 4G and 5G system.It is PHY cell id which is required for DL synchronization. PCI planning is one of the most important steps in 4G and 5G network planning and construction.
What is a cell ID number?
CELLID (CELL ID or CID) is a generally unique number used to identify each Base Transceiver Station (BTS) or sector of a BTS within a location Area Code (LAC) if not within a GSM network.
How do I find my Cell ID?
- Log into the User Console.
- Select the SIM you wish to locate.
- Click `Details` at the top.
- Select `Session Details` Under this tab, it will list each session event, which will list the MCC/MNC as well as the Local Area code and Cell ID.
Why PCI is used in LTE?
The PCI is used for cell identity during cell selection procedure. The purpose of PCI optimization is to ensure to a great extent that neighboring cells should have different primary sequences allocated. Cleaning the PCIs is probably the most effective steps to improve RF performance.
How is physical Cell ID calculated in LTE?
it carried by two synchronization signals (PSS&SSS) as PCI=3xSSS+ PSS after UE read these two signals UE can calculate current PCI configuration of the Cell. PCI in LTE is physical layer Cell Identifier. Its range is from 0-503 total Identities as 504. It is consist of Primary Sync signal and Secondary Sync signal.
What is CGI in 4G?
Cell Global Identity (CGI) is a globally unique identifier for a Base Transceiver Station in mobile phone networks. It consists of four parts: Mobile Country Code (MCC), Mobile Network Code (MNC), Location Area Code (LAC) and Cell Identification (CI).
What is PSC in 3g?
Primary scrambling code: it is similar to Bcch in 2g in that it identifies the cell by ue in downlink. Is is a code ue used to correlate its received signal and decipher the useful message to be received.
What is SSB in 5G?
SS Block(SSB) stands for Synchronization Signal Block and in reality it refers to Synchronization/PBCH block because Synchnronization signal and PBCH channel are packed as a single block that always moves together.
What is PCI and RSI?
The tested network problems are Physical Cell Identity (PCI) conflicts and Root Sequence Index (RSI) collisions and were labeled through configured cell relations that verified these two conflicts. Furthermore, a real LTE network was used.
Why is there no Phich in 5G?
However, in 5G NR, the PHICH and the PCFICH, are not needed. The PHICH is used in LTE to handle uplink retransmissions and is tightly coupled to the use of a synchronous hybrid-ARQ protocol, but since the NR hybrid-ARQ protocol is asynchronous in both uplink and downlink the PHICH is not needed in NR.
What is eNodeB ID in LTE?
Enodeb-id. evolved NodeB IDentifier. Used to identify an eNodeB uniquely within a Public Land Mobile Network (PLMN). The eNB-ID can have either 20 bits or 28 bits. It is also comprised within the Global eNB-ID, which uniquely identifies an eNodeB globally.
What is LAC ID and cell ID?
LAC means Location Area Code, which is a group of cell towers. And CID stands for Cell Identification, referring to the cell number and sometimes a sector. In other words, the CID tells you where the antenna is located and which direction it faced.
What is cell in GSM?
GSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity. There are five different cell sizes in a GSM network—macro, micro, pico, femto and umbrella cells. The coverage area of each cell varies according to the implementation environment.
What is cell ID give an example?
A GSM Cell-ID (CID) is a unique number by which GSM towers or the sector of the GSM tower can be identified within a location area code (LAC) or a GSM network. The first or last digits of a CID represent the sector ID. For example, if a secured M2M or LTE M simcard sees one cell tower, its Cell ID is released.
Is cell ID a grabber?
The LIS Cell ID Grabber is a Cell ID Locating Hardware designed by Avenging Security. In one piece of hardware, we are able to track the radiofrequencies of 2G, 3G, and 4G individually or simultaneously. In addition, ours is faster, more portable, and more efficient, making the task of Cell ID Analyzing much easier.
What is TAC in cell tower?
The Location Area Code/Tracking Area Code, abbreviated as LAC/TAC, is an identifier of the location area within an MNO’s network. This part of the code can be represented using hexadecimal values with a length of two octets. The served area of a cellular radio network is usually divided into location areas.
How many PCI are in 5G?
Physical-layer Cell Identity (PCI) – There are 1008 unique PCIs defined in 5G NR, double of that in LTE (504).
How is PCI calculated?
Per Capita Income (PCI) measures the average income earned per person in a given area (city, region, country, etc.) in a specified year. It is calculated by dividing the area’s total income by its total population. Hence, PCI of a country is calculated by dividing the National Income by total population.
What is CQI in LTE?
In the LTE system, the CQI is used by the mobile to indicate the channel quality to the eNB. The CQI reported value is between 0 and 15. This indicates the level of modulation and coding the UE could operate.
How do you plan a PCI in LTE?
What is PSS and SSS in LTE?
In LTE, there are two downlink synchronization signals which are used by the UE to obtain the cell identity and frame timing. Primary synchronization signal (PSS) Secondary synchronization signal (SSS)
What are LTE identifiers?
Unique identification of mobile (LTE) subscriber Network (MME) gets the PLMN of the subscriber. IMSI (not more than 15 digits) = PLMN ID + MSIN = MCC + MNC + MSIN. PLMN ID. Public Land Mobile Network Identifier. Unique identification of PLMN.
What is KCT cell monitor?
What is it? Cell Signal Monitor is a specialized application for Android devices which checks a state of GSM, UMTS and LTE networks.
