Method And Apparatus For Cell Reselection In Mobile Communications

A method, comprising:

• receiving, by a processor of an apparatus, a redirection frequency;
• receiving, by the processor, a dedicated frequency offset value corresponding to the redirection frequency;
• determining, by the processor, a cell-ranking criterion for an intra-frequency neighboring cell according to the dedicated frequency offset value by:
• counting, based on a valid timer value for the dedicated frequency offset value, a time period in applying the dedicated frequency offset value in the determining of the cell-ranking criterion;
• measuring a reference symbol received power (RSPP) of a serving cell at the redirection frequency;
• measuring a RSRP of the intra-frequency neighboring cell at a different frequency;
• and
• comparing results of the measuring of the RSRP of the serving cell and the measuring of the RSRP of the intra-frequency neighboring cell;
• and
• performing, by the processor, cell reselection to the intra-frequency neighboring cell at the redirection frequency based on a result of the comparing.
