Abstract
Provided are a method for requesting, by a user equipment (UE), system information in a wireless communication system and a device supporting the same. The method may include: initiating a random access procedure; requesting system information from a base station (BS) in the initiated random access procedure; receiving, from the BS, a broadcast indication indicating that the requested system information is broadcast in the initiated random access procedure after requesting the system information from the BS; and stopping the initiated random access procedure.
Claims15
A method performed by a wireless device operating in a wireless communication system, the method comprising:
- triggering a random access procedure for a system information request;
- transmitting, to a base station (BS), a random access preamble for the system information request;
- receiving, from the BS, a random access response in response to the random access preamble for the system information request, wherein the random access procedure for the system information request is considered as completed based on the random access response;
- and
- receiving, from the BS, system information requested by the system information request,
- wherein an acknowledgement of the system information request is informed by a media access control (MAC) layer of the wireless device to a radio resource control (RRC) layer of the wireless device based on the random access response.
A wireless device configured to operate in a wireless communication system, the wireless device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- triggering a random access procedure for a system information request;
- transmitting, to a base station (BS) through the transceiver, a random access preamble for system information request;
- receiving, from the BS through the transceiver, a random access response in response to the random access preamble for the system information request, wherein the random access procedure for the system information request is considered as completed based on the random access response;
- and
- receiving, from the BS through the transceiver, system information requested by the system information request,
- wherein an acknowledgement of the system information request is informed by a media access control (MAC) layer of the wireless device to a radio resource control (RRC) layer of the wireless device based on the random access response.
A processing apparatus for a wireless device configured to operate in a wireless communication system, the processing apparatus comprising:
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- triggering a random access procedure for a system information request;
- transmitting, to a base station (BS), a random access preamble for system information request;
- receiving, from the BS, a random access response in response to the random access preamble for the system information request, wherein the random access procedure for the system information request is considered as completed based on the random access response;
- and
- receiving, from the BS, system information requested by the system information request,
- wherein an acknowledgement of the system information request is informed by a media access control (MAC) layer of the wireless device to a radio resource control (RRC) layer of the wireless device based on the random access response.
