Method for adjusting cell reselection priority for avoiding IDC interference in wireless communication system and device for same
The present invention discloses a method for a first communication module of a user equipment measuring for cell reselection in a wireless communication system. More particularly, the present invention comprises the following steps: receiving a first message including at least one frequency priority list from a base station; receiving a second message from at one or more second communication modules which coexist in the terminal; and measuring the frequency based on the at least one frequency priority list and the operating frequency information that is included in the second message, when the second message indicates the beginning of the operation of the one or more second communication modules.
1. A method of performing a measurement for a cell reselection by a 1 st communication module for a 1 st communication system of a user equipment, the method comprising:
receiving a 1 st message including a frequency priority list for the 1 st communication system from a base station of the 1 st communication system;
receiving a 2 nd message from at least one 2 nd communication module for a 2 nd communication system coexisting in the user equipment; and
if the 2 nd message indicates an operation start of the at least one 2 nd communication module, performing a frequency measurement based on the frequency priority list and an operating frequency information of the 2 nd communication module included in the 2 nd message,
wherein performing the frequency measurement comprises excluding at least one of the operating frequency of the at least one 2 nd communication module and a specific frequency from the frequency priority list,
wherein the operating frequency of the at least one 2 nd communication module is a frequency at which the at least one 2 nd communication module causes interference to the 1 st communication system, and
wherein the specific frequency is a frequency at which the 1 st communication system causes interference to the at least one 2 nd communication module.
2. The method of claim 1 , wherein if the measurement for the cell reselection is performed before the 2 nd message is received, the frequency measurement is performed only based on the frequency priority list.
3. The method of claim 1 , wherein the at least one 2 nd communication module comprises at least one selected from the group consisting of a transceiving module for a WiFi system, a Bluetooth transceiving module and a GPS (global positioning system) receiving module.
4. The method of claim 1 , wherein the operation start of the at least one 2 nd communication module comprises either an operation of turning on a power of the at least one 2 nd communication module or a traffic transceiving operation of the at least one 2 nd communication module.
5. A user equipment in a wireless communication system, the user equipment comprising:
a 1 st communication module configured to transceive signals with a 1 st communication system; and
at least one 2 nd communication module configured to transceive signals with a 2 nd communication system,
wherein the 1 st communication module receives a 1 st message including a frequency priority list for the 1 st communication system from a base station of the 1 st communication system,
wherein the 1 st communication module receives a 2 nd message from at least one 2 nd communication module coexisting in the user equipment, and wherein if the 2 nd message indicates an operation start of the at least one 2 nd communication module, the 1 st communication module performs a frequency measurement based on the frequency priority list and an operating frequency information of the 2 nd communication module included in the 2 nd message,
wherein the 1 st communication module excludes the operating frequency of the at least one 2 nd communication module and a specific frequency from the frequency priority list,
wherein the operating frequency of the at least one 2 nd communication module is a frequency at which the at least one 2 nd communication module causes interference to the 1 st communication system, and
wherein the specific frequency is a frequency at which the 1 st communication system causes interference to the at least one 2 nd communication module.
6. The user equipment of claim 5 , wherein if the measurement for the cell reselection is performed before the 2 nd message is received, the 1 st communication module performs the frequency measurement only based on the frequency priority list.
7. The user equipment of claim 5 , wherein the at least one 2 nd communication module comprises at least one selected from the group consisting of a transceiving module for a WiFi system, a Bluetooth transceiving module and a GPS (global positioning system) receiving module.
8. The user equipment of claim 5 , wherein the operation start of the at least one 2 nd communication module comprises either an operation of turning on a power of the at least one 2 nd communication module or a traffic transceiving operation of the at least one 2 nd communication module.
