Dear Concentric experts

Kindly advise; we have converted some of our Dual cells “GSM & DCS” to Concentric DCS
But we have degradations: kindly share based on your experience

- what’s the most recommended values for Assign Optimum Layer, UtoO HO Received Level Threshold, OtoU HO Received Level Threshold, etc
- Feel free to share any valuable recommendaions

Thanks a lot

Hello

As requested below are the values
Assign Optimum Layer

UtoO HO Received Level Threshold

OtoU HO Received Level Threshold

202015

What i knew is the Parameter in excell file attached should be changed to complete parameter relating to concentric cell behaviour and to see the output of at leat equal distribution of Traffic btn inner zone and outer zone in a single BCCH site. and below in blaket is a must done thing before changing T3105
((
Configuring T3105 is affected by The maximum resend times of physical information . If T3105 is configured to a short value, then the The maximum resend times of physical information

needs to be increased accordingly. ThereforeIt’s supposed to be changed together with (The maximum resend times of physical information/ The maximum repeated times of physical messages) value.

Please change The maximum resend times of physical information to 30 from 20( default value), here T3105 will be possible to be changed to 7 as multiplication of these parameters
will be greater than 180) )
