Abstract
A method of performing, by a device, a random access procedure in a radio communication system includes: receiving from a base station RACH configuration information; and transmitting a first message based on the received RACH configuration information. Herein, a plurality of SSBs may be in association with a plurality of preambles, and the first message may be transmitted in a time domain through a plurality of RACH resources.
Claims20
A method of performing a random access procedure, wherein a device performs a random access procedure in a radio communication system, the method comprising:
- receiving random access channel (RACH) configuration information from a base station;
- and
- transmitting a first message to the base station based on the received RACH configuration information,
- wherein a plurality of synchronization signal blocks (SSB) is respectively in association with a plurality of preambles, and the first message is transmitted in a time domain through a plurality of RACH resources.
A method of performing a random access procedure, wherein a base station performs a random access procedure in a radio communication system, the method comprising:
- determining information to be included in RACH configuration information in consideration of an SSB and RACH resource association relation;
- transmitting the RACH configuration information to a device;
- and
- receiving from the device a first message based on the RACH configuration information, wherein a plurality of SSBs is respectively in association with a plurality of preambles, and the first message is received in a time domain through a plurality of RACH resources.
A device for performing a random access procedure, wherein the device performs a random access procedure in a radio communication system, the device comprising:
- a transmitting unit;
- a receiving unit;
- and
- a processor controlling the transmitting unit and the receiving unit,
- wherein the processor receives RACH configuration information from a base station through the receiving unit, and transmits to the base station a first message based on the received RACH configuration information, wherein a plurality of SSBs is respectively in association with a plurality of preambles, and the first message is transmitted in a time domain through a plurality of RACH resources.
A base station, wherein the base station performs a random access procedure in a radio communication system, the base station comprising:
- a transmitting unit;
- a receiving unit;
- and
- a processor controlling the transmitting unit and the receiving unit,
- wherein the processor determines information to be included in RACH configuration information in consideration of an SSB and RACH resource association relation, transmits to a device the RACH configuration information through the transmitting unit, and receives from the device a first message based on the RACH configuration information, wherein a plurality of SSBs is respectively in association with a plurality of preambles, and the first message is received in a time domain through a plurality of RACH resources.
