Try to find parameter regarding nodeb schedulars,which allocate resources in node-b....which exploits different conditions to give max throughput.

is this issue seen in cdma 1x or wcdma?

+ This value is expected to be best when it more closes towards 100 as it tells you if the MS can listen to the n/w & vice-versa/also your network foot print.
+ But this value clearly impacted by...

sorry forgot to add....

16 qam can allow to transmit total max 4 bits/symbols (data + code)
64 qam can allow to tranmit total max 6 bits/symbols (data + code)

but as the modulation order...

CQI is used by wireles data technologies to provide fast feedback abt the currect status of the UE /rf condition.This along with the HARQ ack/nack ,cell load & specific implementation of schedular in...

i have following observation after seeing the attached snap.

+ there is a clear lack of any dominent CPICH.Iam not sure if its due to buldings ,else its really clear there is some issue with the...

Iam assuming you are talking abt MS in TCH.....in that case Mear_ctrl_msg are send to ms telling the event criteria and also intra/inter neighbour(psc) to look for.

MS then uses internal...

if you don want to touch the antenna...i think you might have to then go for costly solution like small bts meant for IBS rather than repeaters as IBS.

just to add the importance of power control below is the frequency

for gsm - its 2hz
for cdma - its 800hz
for wcdma - its 1500hz (inner loop)

Triggering condition (for a Event 1a) = Indicates which cells can trigger Event 1a

Iam suspecting that the trigger condition for the event1a would be set either to

triggeringCondition :...

what is the triggeringCondition for event1a is it
triggeringCondition : detectedSetAndMonitoredSetCells

or

triggeringCondition : detectedSet

looks more like some hardware malfuntion @ radio of IBS

T314 & T315 are guard timers during which the UE keeps the RABs following radio link failure until they expire or the cell update procedure has been completed. During this time, the RNC can try to...

though i dont have same...i would like to add few points here....

MCS to CINR or SINR tables can be static or dymanic.They are vendor specific.you also take into account the HARQ ACK's or NACK's...

for 21.6 Mbps speed,we are taking full data bits & no correction codes...entire 6 bits of 6 bits for a 64 qam.

but in realty you may max go till 5/6....ie 5 bits of data in the...

to be very simple as you know there is total 128 SF-128 ovsf channel.

For R99

+ now consider 2 sf-128 ( used for PCCSCH/CPICH etc..) used for overhead channel

+ Remaining is 126 SF 128...

Hope below helps!!

Thanks for your post,but I think you are refering to 1st edition of this book...Iam looking for 2nd edition :)

Incase you have it pls let me know.

Thanks

pls check the rach parameter are properly defined else MS will keep on trying & creating UL interference.

Also ensure your VSWR in case you are using...

Dear Minto...is it possible for the same.Many Thanks in advance!!

friends any update!!

is your system on HCS (900/2100 Mhz) or dual carrier

pls specify the vendor

Thanks!!

Friends,does anyone have the recommended parameter setting for below section for Eric , NSN & ALU for UMTS/HSDPA.
