Abstract
Provided are a method for a user equipment (UE) to request system information in a wireless communication system and a device supporting the same. The method may include: transmitting a random access preamble for requesting system information to a base station (BS); receiving, from the BS, a random access response including only a random access preamble identifier (RAPID) corresponding to the transmitted random access preamble; and considering that a random access procedure is completed.
Claims9
A method for requesting, by a user equipment (UE), system information in a wireless communication system, the method comprising:
- transmitting a random access preamble for requesting system information to a base station (BS);
- receiving, from the BS, a random access response (RAR) message including a random access preamble identifier (RAPID) related to the transmitted random access preamble,
- wherein the RAR message does not include a medium access control (MAC) RAR related to the RAPID;
- determining that a random access procedure is completed, based on the RAR message including no MAC RAR related to the RAPID;
- and
- receiving, from the BS, the system information without transmitting a message to the BS in response to the RAR message, based on the determination that the random access procedure is completed.
A user equipment (UE) for requesting system information in a wireless communication system, the UE comprising:
- a memory;
- a transceiver;
- and
- a processor, connected with the memory and the transceiver, that:
- controls the transceiver to transmit a random access preamble for requesting system information to a base station (BS);
- controls the transceiver to receive, from the BS, a random access response (RAR) message including a random access preamble identifier (RAPID) related to the transmitted random access preamble,
- wherein the RAR message does not include a medium access control (MAC) RAR related to the RAPID;
- determines that a random access procedure is completed, based on the RAR message including no MAC RAR related to the RAPID;
- and
- controls the transceiver to receive, from the BS, the system information without transmitting a message to the BS in response to the RAR message, based on the determination that the random access procedure is completed.
