Abstract
Provided is a method and an apparatus for performing a random access process in a wireless communication system. A wireless device transmits a random access preamble, based on a random access resource, to a base station, then receives a random access response to the random access preamble. The random-access resource can be set to the wireless device or to the group to which the wireless device belongs.
Claims13
A method of performing a random access procedure by a radio device in a wireless communication system, the method comprising:
- receiving configuration information for a random access resource from a base station;
- transmitting a random access preamble to the base station based on the random access resource;
- receiving a random access response in response to the random access preamble;
- and
- transmitting a scheduled message to the base station, wherein the random access resource is configured for the radio device or a group to which the radio device belongs.
A radio device performing a random access procedure in a wireless communication system, the radio device comprising:
- an RF (radio frequency) unit transmitting and receiving a radio signal;
- and
- a processor connected with the RF unit, wherein the processor,
- receives configuration information for a random access resource from a base station;
- transmits a random access preamble to the base station based on the random access resource;
- receives a random access response in response to the random access preamble;
- and
- transmits a scheduled message to the base station, wherein the random access resource is configured for the radio device or a group to which the radio device belongs.
