Method for transmitting sidelink terminal information of terminal in wireless communication system and terminal utilizing the method
Provided are a method for transmitting sidelink terminal information of a terminal in a wireless communication system and a terminal utilizing the method. The method receives a request for a sidelink system information report from a serving cell located on a first frequency, wherein the sidelink system information report request is a message requesting a report of system information associated with a sidelink action acquired from another cell of a second frequency, and sidelink terminal information, comprising system information associated with the sidelink action acquired from another cell of the second frequency, is reported to the serving cell.
1. A method for reporting first information in a wireless communication system, the method performed by a user equipment (UE) and comprising:
receiving, from a serving cell on a first frequency, second information which includes a request to report the first information;
acquiring, from a cell on a second frequency, system information including parameters related to a sidelink discovery procedure;
selecting a target cell on the second frequency;
reporting, to the serving cell, the first information which includes the parameters acquired from the system information and an identifier (ID) of the target cell; and
receiving a sidelink configuration related to the target cell from the serving cell,
wherein the second frequency is different from the first frequency,
wherein the first information is reported within a predetermined time duration, and
wherein the UE performs the sidelink discovery procedure on the target cell based on the sidelink configuration.
2. The method of claim 1 , wherein the first information is sidelink UE information.
3. The method of claim 1 , wherein upon the receiving of the second information, a timer is started.
4. The method of claim 3 , wherein the timer stops upon the reporting of the first information.
5. The method of claim 3 , wherein when the timer expires, the acquiring of the system information is stopped.
6. The method of claim 1 , wherein the first information includes an identity (ID) of a public land mobile network (PLMN) to which the cell on the second frequency belongs.
7. The method of claim 6 , wherein the first information further includes a cell ID of the cell on the second frequency.
8. The method of claim 6 , wherein the first information further includes information on the second frequency.
9. The method of claim 1 , wherein the first information includes at least one of sidelink reception resource information, sidelink transmission resource information, transmission power configuration information, synchronization information, and cell selection or reselection information.
10. The method of claim 1 , wherein the system information is system information block (SIB) 19, which includes information on the sidelink discovery procedure.
11. A user equipment (UE) comprising:
a transceiver configured to transmit and receive a radio frequency signal; and
a processor operatively coupled to the transceiver,
wherein the processor is configured to:
control the transceiver to receive, from a serving cell on a first frequency, second information which, includes a request to report first information,
acquires, from a cell on a second frequency, system information including parameters related to a sidelink discovery procedure,
selects a target cell on the second frequency,
reports, to the serving cell, the first information which includes the parameters acquired from the system information and an identifier (ID) of the target cell, and
receives a sidelink configuration related to the target cell from the serving cell,
wherein the second frequency is different from the first frequency,
wherein the first information is reported within a predetermined time duration, and
wherein the UE performs the sidelink discovery procedure on the target cell based on the sidelink configuration.
