)n a GSM networ$" S ser&ices and low2rate PS ser&ices 0in S/2S6 or MS/2MS6 mode5 use theGMS= modulation scheme" and high2rate PS ser&ices 0in MS72MS> mode5 use the ;PS=modulation scheme!

The pea$ power in ;PS= modulation scheme is higher than that in GMS= modulation scheme when thea&erage powers are the same! ompared with the ma+imum output power of the T9: in GMS=modulation scheme" the ma+imum output power of the T9: in ;PS= modulation scheme is decreasedto a fi+ed e+tent! Thus" the ma+imum output power of the DT9: or multi2carrier T9: with high2rate PSser&ices is lower than that of the DT9: or multi2carrier T9: with S ser&ices! %s a result" the a&eragepower in ;PS= modulation scheme is lower than that in GMS= modulation scheme! The MS recei&egain is related to the a&erage transmit power of the BTS! Therefore" the PS ser&ices in ;PS=modulation scheme cannot be pro&ided on the edge of a cell" and thus the networ$ performance doesnot reach the optimum le&el!

)n the e+isting networ$" the BS controls multiple BTSs and manages BTS radio resources" and theBTS handles ser&ices! )n the case of PS ser&ices" the BTS determines whether to use GMS= or ;PS=modulation scheme according to the ser&ice type of the BS! )n ;PS= modulation scheme" thema+imum transmit power of a T9: is impro&ed through enhanced -DG- co&erage so that thema+imum output power of high2rate PS ser&ices is the same as that of S ser&ices! )n this way" thea&erage output power of high2rate PS ser&ices in ;PS= modulation scheme is the same as that of Sser&ices!

9egarding DT9: and multi2carrier T9:" enhanced -DG- co&erage helps impro&e the ma+imum outputpower of high2rate PS ser&ices through different mechanisms!

The ma+imum output power in ;PS= modulation scheme must not e+ceed that in GMS= modulationscheme to a&oid impacts on networ$ planning!

-nhanced -DG- co&erage helps impro&e networ$ performance in the following ways<

)ncreasing the networ$ co&erage so that the co&erage area of high2rate PS ser&ices is almost the

same as that of S ser&ices!

)ncreasing the transmit power! The ?) of calls is impro&ed! )n this way" a higher2order modulationscheme can be used to increase the uplin$ and downlin$ data rate!

For the DT9:" if one of the two carriers that belong to the same cell and DT9: is idle at a transmitmoment" then PS ser&ices are transmitted by the two carriers at the same time! That is" dynamictransmit di&ersity or dynamic PBT is used to transmit PS ser&ices! )n this case" the ma+imum outputpower of high2rate PS ser&ices can reach to a le&el as that of S ser&ices when the DT9: is inseparated or combined transmit mode!
