Hi everyone,

My company is considering organising a telecoms related evening for some of our clients in the UK. I would like to use LTEⁱ/4G as our main theme and will invite 4 or 5 speakers to host the event with presentations on topics in the LTE domain. What topics do you think would work? The idea of the event is for people to learn about the up and coming technologies whilst networking.

Hi,

I want to estimate the soft symbols from LLRs coming from Decoder using the tanh function. The question is how are the bits mapped to symbols let say for 16-QAMⁱ:

In the specification it is written that the bits b(i),b(i+1),b(i+2),b(i+3) are mapped to the I and Q as for instance:

I Q
0000 1/sqrt(10) 1/sqrt(10)

0001 1/sqrt(10) 3/sqrt(10)

Hi,

I'm new to LTEⁱ so apologies up front for my severe lack of knowledge.

1. Bandwidth limits and typical amount used for a voice call

From what I have read thus far it seems that the handset could use anywhere from six to one-hundred resource blocks of 180kHz(~1.1 MHz to 20 MHz range). Is this true? It would be useful to understand how much would be used typical for a voice call?

I have been doing my final task to simulating inter-MMEⁱ handover. i would ask some questions:
1. What kind of simulator could i use which i can simply applicate for handover?
2. Could here anybody help to explain me about the function or job of S1ⁱ interface when inter-MME handover or inter-eNodeBⁱ handover?

Could anybody explain that how the cells(sectors) are mapped on RRCⁱ. i mean who handles and maintains the eNodeb call & sector information and how the upper layers handle these things. I am aware of phy procedures but what happens on upper layers like RRC & others??

Hi,

I am having document 32.592.Lot of parameters given in this document are considered as operator settable. This document has been written for femto.

Hi,

I am currently working on 3G FemtoCell. I know that LTEⁱ doesn't support voice call as result when the voice call is made UEⁱ would fall back to UMTS/CDMA network to handle the cs call.

When my UEⁱ initially attaches to the network I see that the MMEⁱ makes 2 separate DIAMETER Authentication Information Requests to the HSS and receives 2 different E-UTRANⁱ vectors back in return.

3GPPⁱ 32.450 (Rel 9) section 6.5.1.1 mention mobility KPI and gives formula for mobility success rate.

Dear Friends,

I am trying to understand the difference between Type 1 and Type 2 Timing Advance in LTEⁱ.

Please can one of the LTE Gurus illuminate?

Here is an excerpt from 36.305

Whether somebody can give the detailed answer to the following question: what for it is necessary to create network LTEⁱ when already exists WiMAX? What for to invent a bicycle?

Was wondering if LTEⁱ can support public safety? Let say if the base stations is affected, can the walkie-talkie/comm sets be able to communicate via DMO (direct mode operations) assuming in tunnel.

What do you think about this blog entry on 4g and LTEⁱ?
