It is not mandatory that Rx_Qual will be bad.During HO command,the MS is measuring nothing,so it is pointless to say that Rx_qual is good or bad,as no SACCH is there in DL at the time of HO command.What happens is for the DL SACCH which is scheduled around the time BSC gives the HO command to MS,it is this SACCH Block which is filled with dummy SACCH,TEMS/MS just decodes it & gives the Rx_Qual value,whatever it is.
Please let me know if any doubt still persists
