Abstract
A method and user equipment (UE) for performing a cell reselection procedure is provided. The method includes receiving priority information about frequencies, performing cell measurement, based on the priority information, and performing a cell reselection procedure, based on a result of the cell measurement.
Claims10
A method, performed by a user equipment (UE), of performing a cell reselection procedure, the method comprising:
- receiving priority information about one or more frequencies;
- performing a serving cell measurement based on a signal received from a serving cell;
- identifying at least one frequency among the one or more frequencies, based on the serving cell measurement and the priority information;
- performing ranking of cells related with the identified at least one frequency including a first frequency and a second frequency, based on measurements performed on the at least one frequency, wherein the cells fulfill cell selection criterion S, and a new radio (NR) frequency includes the first frequency and the second frequency;
- and
- performing cell reselection by selecting at least one cell with highest number of beams above a first threshold value, from among candidate cells,
- wherein the candidate cells include cells having rank values within a value of a rangeToBestCell parameter from a rank value of highest ranked cell among the ranked cells,
- wherein for the first frequency configured with an absThreshSS-BlocksConsolidation parameter, the first threshold value is the absThreshSS-BlocksConsolidation parameter, and
- wherein for the second frequency not configured with an absThreshSS-BlocksConsolidation parameter, the candidate cells include a cell on the second frequency, the cell on the second frequency has one beam, for which measurement is greater than the first threshold value.

- perform ranking of cells related with the identified at least one frequency including a first frequency and a second frequency, based on measurements performed on the at least one frequency, wherein the cells fulfill cell selection criterion S and a new radio (NR) frequency includes the first frequency and the second frequency, and
- perform cell reselection by selecting at least one cell with highest number of beams above a first threshold value, from among candidate cells,
- wherein the candidate cells include cells having rank values within a value of a rangeToBestCell parameter from a rank value of highest ranked cell among the ranked cells,
- wherein when an absThreshSS-BlocksConsolidation parameter is configured for the first frequency, the first threshold value is the absThreshSS-BlocksConsolidation parameter, and
- wherein when an absThreshSS-BlocksConsolidation parameter is not configured for the second frequency, the candidate cells include a cell on the second frequency, the cell on the second frequency has one beam, for which measurement is greater than the first threshold value.
