Classification: CPC H | IPC H

Claim 0:
1. A method performed by a wireless device configured to operate in a wireless communication system, the method comprising:
performing an initial cell selection comprising:
i) scanning all radio frequency (RF) channels in New Radio (NR) bands according to capabilities;
ii) searching for a strongest cell on each frequency; and
iii) selecting a suitable cell;

performing cell reselection evaluation of non-serving cells for cell reselection;
performing a cell reselection to a new serving cell from among the non-serving cells at a first time point during a time duration;
receiving cell reselection parameters comprising speed dependent reselection parameters in system information from the new serving cell; and
determining a mobility state of the wireless device based on the cell reselection parameters,
wherein the cell reselection parameters further comprise information about a first time range and a weight related to the first time range, and
wherein determining the mobility state of the wireless device comprises:
i) calculating a time interval between the first time point and a second time point at which a preceding cell reselection of the cell reselection is performed during the time duration; and
ii) increasing a mobility counter by a number N,

wherein the number N is set to the weight related to the first time range based on the time interval being within the first time range, and
wherein the number N is set to 1 based on the time interval not being within the first time range.
