USER EQUIPMENT AND METHOD FOR HANDLING CELL RESELECTION PROCEDURE
A UE and a method for handling a cell reselection procedure are provided. The method receives, from a camped cell, information related to the cell reselection procedure. The method determines whether the camped cell operates on a first frequency range for a Non-Terrestrial Network (NTN) operation. The method performs a measurement, for the cell reselection procedure for selecting a suitable cell, based on the information related to the cell reselection procedure after determining that the camped cell operates on the first frequency range for the NTN operation.
1 . A method for handling a cell reselection procedure performed by a user equipment (UE), the method comprising:
receiving, from a camped cell, information related to the cell reselection procedure;
determining whether the camped cell operates on a first frequency range for a Non-Terrestrial Network (NTN) operation; and
performing a measurement for the cell reselection procedure for selecting a suitable cell, based on the information related to the cell reselection procedure after determining that the camped cell operates on the first frequency range for the NTN operation.
2 . The method of claim 1 , wherein:
the measurement is performed every time period, and
the time period is determined based on the information related to the cell reselection procedure.
3 . The method of claim 2 , wherein the time period is determined based on a density level of a Terrestrial Network (TN) deployment indicated by the information related to the cell reselection procedure.
4 . The method of claim 2 , wherein the time period is determined based on area information of a neighboring cell indicated by the information related to the cell reselection procedure.
5 . The method of claim 2 , wherein the time period is determined based on a serving time of the camped cell indicated by the information related to the cell reselection procedure.
6 . The method of claim 1 , wherein the information related to the cell reselection procedure indicates at least one of:
one or more frequency ranges,
a density level of a Terrestrial Network (TN) deployment,
area information of a neighboring cell,
a serving time of the camped cell,
a network operation corresponding to each of the one or more frequency ranges, the network operation being an NTN operation or a TN operation, or
a priority corresponding to each of the one or more frequency ranges.
7 . The method of claim 6 , wherein the measurement is performed on at least one of the one or more frequency ranges that is for the TN operation.
8 . The method of claim 6 , wherein:
the measurement is performed on at least one of the one or more frequency ranges that has a priority higher than a first priority of the first frequency range.
9 . The method of claim 6 , wherein:
the one or more frequency ranges include a second frequency range for the TN operation and the first frequency range for the NTN operation, and
a second priority of the second frequency range is higher than a first priority of the first frequency range.
10 . The method of claim 1 , wherein the information related to the cell reselection procedure is received via system information (SI) broadcast by the camped cell.
11 . The method of claim 1 , wherein the information related to the cell reselection procedure is received via radio resource control (RRC) signaling.
12 . A user equipment (UE) for handling a cell reselection procedure, comprising:
one or more processors; and
at least one non-transitory computer-readable medium coupled to at least one of the one or more processors, and storing one or more computer-executable instructions that, when executed by the at least one of the one or more processors, cause the UE to:
receive, from a camped cell, information related to the cell reselection procedure;
determine whether the camped cell operates on a first frequency range for a Non-Terrestrial Network (NTN) operation; and
perform a measurement, for the cell reselection procedure for selecting a suitable cell, based on the information related to the cell reselection procedure after determining that the camped cell operates on the first frequency range for the NTN operation.
13 . The UE of claim 12 , wherein:
the measurement is performed every time period, and
the time period is determined based on the information related to the cell reselection procedure.
14 . The UE of claim 13 , wherein the time period is determined based on at least one of:
a density level of a Terrestrial Network (TN) deployment indicated by the information related to the cell reselection procedure,
area information of a neighboring cell indicated by the information related to the cell reselection procedure, or
a serving time of the camped cell indicated by the information related to the cell reselection procedure.
15 . The UE of claim 12 , wherein the information related to the cell reselection procedure indicates at least one of:
one or more frequency ranges,
a density level of a Terrestrial Network (TN) deployment,
area information of a neighboring cell,
a serving time of the camped cell,
a network operation corresponding to each of the one or more frequency ranges, the network operation being an NTN operation or a TN operation, or
a priority corresponding to each of the one or more frequency ranges.
16 . The UE of claim 15 , wherein the measurement is performed on at least one of the one or more frequency ranges that is for the TN operation.
17 . The UE of claim 15 , wherein:
the measurement is performed on at least one of the one or more frequency ranges that has a priority higher than a first priority of the first frequency range.
18 . The UE of claim 15 , wherein:
The one or more frequency ranges include a second frequency range for the TN operation and the first frequency range for the NTN operation, and
a second priority of the second frequency range is higher than a first priority of the first frequency range.
19 . The UE of claim 12 , wherein the information related to the cell reselection procedure is received via system information (SI) broadcast by the camped cell.
20 . The UE of claim 12 , wherein the information related to the cell reselection procedure is received via radio resource control (RRC) signaling.
