Method and apparatus for reselecting cell based on slice information in wireless communication system
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate and provides a method performed by a user equipment (UE) in a wireless communication system. The method includes identifying a measurement capability of the UE for a cell reselection, and receiving, from a base station, a radio resource control (RRC) release message including configuration information related to cell reselection priorities based on the measurement capability of the UE. The configuration information related to the cell reselection priorities comprises a freqPriorityListNR list and a freqPriorityListDedicatedSlicing list.
1 . A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
identifying a measurement capability of the UE for a cell reselection; and
receiving, from a base station, a radio resource control (RRC) release message including configuration information related to cell reselection priorities,
wherein the configuration information related to the cell reselection priorities comprises a frequency priority list new radio (freqPriorityListNR) and a freqPriorityListDedicatedSlicing, and
wherein in case that a frequency is configured in both the freqPriorityListNR and freaPriorityListDedicatedSlicing, the frequency is counted once.
2 . The method of claim 1 , wherein a maximum number of frequencies is configured up to eight through the freqPriorityListNR and the freqPriorityListDedicatedSlicing.
3 . The method of claim 2 , wherein the maximum number of the frequencies is determined based on the measurement capability of the UE.
4 . The method of claim 1 , wherein the method further comprises:
identifying a cell reselection priority value based on the configuration information related to the cell reselection priorities.
5 . A method performed by a base station in a wireless communication system, the method comprising:
receiving information related to a measurement capability of a user equipment (UE) for a cell reselection; and
transmitting, to the UE, a radio resource control (RRC) release message including configuration information related to cell reselection priorities based on the measurement capability of the UE,
wherein the configuration information related to the cell reselection priorities comprises a frequency priority list new radio (freqPriorityListNR) and a freqPriorityListDedicatedSlicing, and
wherein in case that a frequency is configured in both the freqPriorityListNR and freqPriorityListDedicatedSlicing, the frequency is counted once.
6 . The method of claim 5 , wherein a maximum number of frequencies is configured up to eight through the freqPriorityListNR and the freqPriorityListDedicatedSlicing.
7 . The method of claim 6 , wherein the maximum number of the frequencies is determined based on the measurement capability of the UE.
8 . The method of claim 5 , wherein a cell reselection priority value is identified based on the configuration information related to the cell reselection priorities.
9 . A user equipment (UE) of a wireless communication system, the UE comprising:
a transceiver; and
at least one processor configured to:
identify a measurement capability of the UE for a cell reselection, and
receive, from a base station, a radio resource control (RRC) release message including configuration information related to cell reselection priorities based on the measurement capability of the UE,
wherein the configuration information related to the cell reselection priorities comprises a frequency priority list new radio (freqPriorityListNR) and a freqPriorityListDedicatedSlicing, and
wherein in case that a frequency is configured in both the freqPriorityListNR and freqPriorityListDedicatedSlicing, the frequency is counted once.
10 . The UE of claim 9 , wherein a maximum number of frequencies is configured up to eight through the freqPriorityListNR and the freqPriorityListDedicatedSlicing.
11 . The UE of claim 10 , wherein the maximum number of the frequencies is determined based on the measurement capability of the UE.
12 . The UE of claim 9 , wherein the at least one processor further configured to:
identify a cell reselection priority value based on the configuration information related to the cell reselection priorities.
13 . A base station of a wireless communication system, the UE comprising:
a transceiver; and
at least one processor configured to:
receive information related to a measurement capability of a user equipment (UE) for a cell reselection, and
transmit, to the UE, a radio resource control (RRC) release message including configuration information related to cell reselection priorities based on the measurement capability of the UE,
wherein the configuration information related to the cell reselection priorities comprises a frequency priority list new radio (freqPriorityListNR) and a freqPriorityListDedicatedSlicing, and
wherein in case that a frequency is configured in both the freqPriorityListNR and freaPriorityListDedicatedSlicing, the frequency is counted once.
14 . The base station of claim 13 , wherein a maximum number of frequencies is configured up to eight through the freqPriorityListNR and the freqPriorityListDedicatedSlicing.
