Digital Standard 3GPP W-CDMA (FDD)SMIQThis display shows at a glance whether assigned code domains of various channels overlap, i.e.whether a domain conflict occurs. The symbol rates of code channels are indicated by the width of theassociated bars. The height of the bars gives the power of the code channel. If a bar is grey, the codedomain at this position is assigned once which means that no conflicts occur. If a bar is black (at leastpartly), the code domain is assigned at least twice and conflicts occur.Fig. 2-128WCDMA/3GPP – BS CONFIGURATION / CODE DOMAIN menu (with conflict)Display of domain conflictsIf a domain conflict occurs in the base station/mobile station, this conflict is displayed at two locations(next to the code domain display).1. Centrally for the whole station in the status line ,2. All lines in the channel table (processed in ascending channel numbers) showing a domain conflictin a row with a lower index are indicated with a warning symbol to the left of STATE.A domain conflict occurs when the assigned domains of different channel rows overlap. The assignedcode domain of a channel is calculated from the symbol rate of the channel, the minimum possiblesymbol rate (depending on the link direction), the chip rate and the channelization code number usingthe following equation:current _ symbolrateDomain _ factor = (the minimum symbol rate is 7.5 ksps in downlink),minimum_ symbolratewhere:Lower domain limit = current channelization code number * domain factorUpper domain limit = lower domain limit + domain_factor –1.If the cursor is positioned on one of the warning symbols and if the SELECT button is clicked, a windowis opened and shows more accurate information about the domain conflict that has occurred. The numbersof channel rows in the channel table and the assigned domains of the conflicting channels are displayed.Fig. 2-129WCDMA/3GPP – BS CONFIGURATION / CODE DOMAIN CONFLICT menu1125.5555.03 2.212E-9
