Method of reporting system information in a wireless communication system and device for supporting same

摘要

The present invention relates to a method for a terminal to report system information in a wireless communication system. The method includes: transmitting a previously-obtained system information availability indicator that indicates to a serving cell that there is previously obtained system information on a neighboring cell; and receiving a system report request from the serving cell; and transmitting a system information report to the serving cell in response to the system report request. The system report request includes a previously obtained system information report request indicator. When the previously obtained system information report request indicator indicates that there is a report on the previously obtained system information, the system information report includes the previously obtained system information and the previously obtained system information is system information obtained from the neighboring cell before the system report request is received.

1. A method of reporting, by user equipment, system information in a wireless communication system, the method comprising:
transmitting a ready-acquired system information availability indicator notifying a serving cell that ready-acquired system information about a neighboring cell is present, and control information about the ready-acquired system information to the serving cell wherein the control information comprises:
information about an identifier of the neighboring cell related to the ready -acquired system information;indication information indicating a point of time at which the ready -acquired system information was acquired; andinformation indicating a type of ready-acquired system information; receiving a system information reporting request from the serving cell; and sending a system information report to the serving cell in response to the system reporting request, wherein if the system reporting request comprises a ready-acquired system information reporting request indicator and the ready-acquired system information reporting request indicator indicates that the ready-acquired system information is to be reported, the system information report comprises the ready-acquired system information, wherein the ready-acquired system information is system information acquired from the neighboring cell before receiving the system reporting request; if the system reporting request comprises the ready-acquired system information reporting request indicator and the ready-acquired system information reporting request indicator indicates that the system information is to be acquired from the neighboring cell and to be reported, acquiring new system information from the neighboring cell and reporting the newly acquired system information to the serving cell; and if the system reporting request does not include the ready-acquired system information reporting request indicator, acquiring the new system information from the neighboring cell and reporting the new acquired system information to the serving cell.
