what is the legal total number of PRBs in a cell within a 3GPPⁱ lTE system (relaese8)that the eNB has the authority to distribute among the users ?

Dear Expert ,

I'm working on X2ⁱ handover decision in LTEⁱ, I want to know when the source eNB decides to do handover and what kind of messages they transferred in this phase ?

I believe the tool in
http://paul.wad.homepage.dk/LTE/lte_resource_grid.html

has a bug. When 1.4 MHz and 4 PDCCH OFDMⁱ symbol are generated for 1 antenna port configuration, the RS signals for the 2nd port (which must be assumed if actual config has only 1 port), are not being reserved. Instead, they are marked as being assigned for PDCCH, which I think is wrong ?

Hi

We are testing our LTEⁱ femto-cell base station with various devices, and although we have successfully tested it with Verizon and Vodafone dongles (manufactured by Pantech and Huawei respectively), we are facing issues with attaching the iPad mini to it.

Hi,
I am looking for an Open eNodeBⁱ freeware to run some tests and that has open API interfaces that allow me extend its functionalities.

If someone knows about one or some open eNodeB, I will appreciate that she/he shares it with me.

Thanks

Hi !

I read in the book of E.Dahlman "4G LTEⁱ/LTE-A for Mobile Broadband" that the minimum allocation unit for the scheduler is a Resource Block Pair (two RBs contugous in time domain).

However, I noticed that in the tables of determination of Transport Block Size (TBS ) in 3GPPⁱ specs, the granularity of RBs allocated is only one RB.

Dear Expert ,

I have Query about In Lte to UMTS/GRAN network handover is it mandatory to configure S3 interface. Please Explain .

Hi,

I'm in my first year of my Thesis which is related to LTEⁱ Advanced.
I would like to simulate an LTE-A network.
Can you please advise me about the best Open Source Simulator (simple and efficient one).

Hi, We are in the process of putting together elements we need for a new deployment of LTEⁱ technology based Network in West Africa covering few cities with backhaul Data Traffic to Layer 2 or 3 level backbone. We would like to cover around 1000 multi-points and a scaleable network as needed.

I have only recently started understanding the PHY layer of ODFMA based LTEⁱ. Visualizing what exactly happens at Layer 1 is a little more challenging than at protocol stack level.

Dear All,

How do we ensure Backhauling for Small Cell sites? Normally it should be done wirelessly, but what about interference?

Thank you in advance

Anas

Hi Friends,

The X2ⁱ interface enables eNodeBs de to communicate directly between each other whitch is good for Interference management (especially in HetNets) and seamless HandOver. I read that it is a logical interface not hard one. So I want to understand how it is done softly and whitch protocol is used? Do someone have an idea about this?

Thanks in advance.
