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.
Claims12
A method of performing a random access procedure in a wireless communication system, the method performed by a machine-type communication (MTC) device and comprising:
- receiving configuration information for a random access procedure from a base station,
- wherein the configuration information includes resource information for transmitting a random access preamble, root index information for generating the random access preamble and activation information to perform the random access procedure using the resource information, and
- wherein the resource information and the root index information are specific to the MTC device;
- generating the random access preamble based on the root index information;
- transmitting, to the base station, the random access preamble on a random access resource determined based on the resource information;
- 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 MTC device or a group to which the MTC device belongs.
A machine-type communication (MTC) device for performing a random access procedure in a wireless communication system, the MTC device comprising:
- a radio frequency (RF) unit configured to transmit and receive a radio signal;
- and
- a processor connected with the RF unit, wherein the processor is configured to:
- receive configuration information for a random access procedure from a base station,
- wherein the configuration information includes resource information for transmitting a random access preamble, root index information for generating the random access preamble and activation information to perform the random access procedure using the resource information, and
- wherein the resource information and the root index information are specific to the MTC device;
- generate the random access preamble based on the root index information;
- transmit, to the base station, the random access preamble on a random access resource determined based on the resource information;
- receive a random access response in response to the random access preamble;
- and
- transmit a scheduled message to the base station,
- wherein the random access resource is configured for the MTC device or a group to which the MTC device belongs.
