QGIS - Merge same long lat points with different data into a unique one

I have a layer where there is more than 1 feature for a same object. Imagine i have a layer called signals. There can be up to 10 features in the same place (long/lat) for a unique signal but the features can have different fields or not. I want to traspose (ms access term) those fields from vertical to horizontal (1 unique row). Is this possible in QGIS?

Imagine the following geographic features:

Feature 1               
Long    Lat   Field1    Field2  Field3
x        y    a         b       c


Feature 2               
Long    Lat   Field1    Field2  Field3  
x       y     a         b       d

What i need is to obtain:

Feature             
Long    Lat   Field1    Field2   Field3_1   Field3_2    
x       y     a         b        c          d

Is this posiible in QGIS?
