+ *  * @brief : This Function fills the Coreset and SS info based on PDCCH Cfg received for a UE
+ *
+ *     Function : fillUeCoresetAndSsInfo
+ *
+ * For a Coreset, capture the following details which will be used during pdcch allocation
+ *   [Step 1]: Count number of RBG and calculate TotalPRBs which can be used 
+ *   [Step 2]: Get the reference pointer for Coreset and Its SearchSpace.
+ *   [Step 3]: A CCE will have 6 RBs in TOTAL. If duration increases, CCE will
+ *             occupy less number of PRBs(1RB x 1 OFDM Symbol). Eg. If duration = 2, then
+ *             instead of 6 PRBs, CCE will only occupy 3 PRBs and 2 OFDM symbols.
+ *   [Step 4]: Based on CoresetSize, fill AggLvl-CQI mapping by calculating the dciSize.
+ *   [Step 5]: Calculate Y value for this coreset and UE
+ *
+ *   @Params[in]: UeCb,
+ *  [return]: ROK, RFAILED : Memory allocation failure.
