Thanks for answers..
if this is for umts
multicarrier=more than one..e.g. f1+f2+f3..
dual carrier consists only two carriers

Re: What is the difference between Multi Carrier and Dual Carrier ?
Multi carrier assumes that you are transmitting over a number of sub-carriers which are usually orthogonal among themselves. This tranmission method is adopted in WiMAX, LTE as OFDM but it was used as multi carrier meny years before in military communications. Dual carrier has several meanings but mostly it measn transmitting on only 2 carriers (usually called I/Q tranmission because carriers are othogonal)/ This is seen in regular modulations like PSK, QAM etc...

Re: What is the difference between Multi Carrier and Dual Carrier ?
There is MC-HSPA+ that uses 2 or more independent 5MHz channels to provide higher data rates. Qualcomm is experimenting with that... That is R8.
Take a look at http://www.qualcomm.com/media/videos/multi-carrier-hspa

Re: What is the difference between Multi Carrier and Dual Carrier ?
Multi Carrier usually refers to a cell with multiple frequencies (F1, F2, F3 etc)
Dual carrier is usually a terminology associated with the feature introduced in 3GPP R8 allowing higher data rates mainly 42Mbps

Multi carrier: 1 Sector has multiple frequencies (f1, f2..) and 1 user only use 1 frequencies
Dual carrier : 1 user can use 2 frequencies to get high data rate
