Method for reporting radio link failure in wireless communication system, and device therefor
A user equipment for transmitting and receiving a signal in a wireless communication system, includes: a transceiver; and at least one processor configured to perform a random access procedure with a base station and record log information that is information related to the random access procedure, wherein the random access procedure includes transmitting a random access preamble to the base station and receiving, from the base station, a random access response that is a response to the transmission of the random access preamble.
1. A method, performed by a user equipment (UE), of reporting information about a random access procedure, the method comprising:
storing the information about the random access procedure, wherein the information about the random access procedure comprises a list regarding at least one synchronization signal block (SSB) selected by UE and a list regarding random access attempts associated with the at least one SSB with received power reference signal (RSRP) exceeding a configured threshold value;
receiving, from a base station, a request for reporting the information about the random access procedure; and
transmitting, to the base station, a message including the stored information about the random access procedure.
2. The method of claim 1 , wherein the information about the random access procedure further comprises information about a number of times a random access preamble is transmitted.
3. The method of claim 1 , further comprising providing, to the base station, information about whether a function of reporting the information about the random access procedure is supported.
4. The method of claim 1 , further comprising receiving, from the base station, configuration information about a random access procedure configured based on the information about the random access procedure.
5. A method, performed by a base station, of obtaining information about a random access procedure, the method comprising:
transmitting, to a user equipment (UE), a request for reporting the information about the random access procedure; and
receiving, from the UE, a message including the information about the random access procedure,
wherein the information about the random access procedure comprises a list regarding at least one synchronization signal block (SSB) selected by UE and a list regarding random access attempts associated with the at least one SSB with received power reference signal (RSRP) exceeding a configured threshold value.
6. The method of claim 5 , wherein the information about the random access procedure further comprises information about a number of times a random access preamble is transmitted.
7. The method of claim 5 , further comprising receiving, from the UE, information about whether a function of reporting the information about the random access procedure is supported.
8. The method of claim 5 , further comprising transmitting, to the UE, configuration information about a random access procedure configured based on the information about the random access procedure.
9. A user equipment (UE) for reporting information about a random access procedure, the UE comprising:
a transceiver; and
a processor coupled with to the transceiver and configured to:
store the information about the random access procedure, wherein the information about the random access procedure comprises a list regarding at least one synchronization signal block (SSB) selected by UE and a list regarding random access attempts associated with the at least one SSB with received power reference signal (RSRP) exceeding a configured threshold value,
receive, from a base station, a request for reporting the information about the random access procedure, and
transmit, to the base station, a message including the stored information about the random access procedure.
10. The UE of claim 9 , wherein the information about the random access procedure further comprises information about a number of times a random access preamble is transmitted.
11. The UE of claim 9 , wherein the processor is further configured to provide, to the base station, information about whether a function of reporting the information about the random access procedure is supported.
12. The UE of claim 9 , wherein the processor is further configured to receive, from the base station, configuration information about a random access procedure configured based on the information about the random access procedure.
13. A base station for obtaining information about a random access procedure, the base station comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
transmit, to a user equipment (UE), a request for reporting the information about the random access procedure, and
receive, from the UE, a message including the information about the random access procedure,
wherein the information about the random access procedure comprises a list regarding at least one synchronization signal block (SSB) selected by UE and a list regarding random access attempts associated with the at least one SSB with received power reference signal (RSRP) exceeding a configured threshold value.
14. The base station of claim 13 , wherein the information about the random access procedure further comprises information about a number of times a random access preamble is transmitted.
15. The base station of claim 13 , wherein the processor is further configured to receive, from the UE, information about whether a function of reporting the information about the random access procedure is supported.
16. The base station of claim 13 , wherein the processor is further configured to transmit, to the UE, configuration information about a random access procedure configured based on the information about the random access procedure.
