Abstract
An operation method of a terminal in a communication system may comprise receiving first random access (RA) configuration information and second RA configuration information from a base station; transmitting a Msg1 to the base station based on the second RA configuration information; receiving a Msg2, which is a response to the Msg1, from the base station; and repeatedly transmitting a Msg3 K times to the base station.
Claims20
A terminal, comprising:
- a processor,
- wherein the processor causes the terminal to:
- receive first random access (RA) configuration information and second RA configuration information from a base station;
- transmit a Msg1 to the base station based on the second RA configuration information;
- receive a Msg2, which is a response to the Msg1, from the base station;
- and
- repeatedly transmit a Msg3 K times to the base station,
- wherein the Msg3 is not repeatedly transmitted in a first RA procedure according to the first RA configuration information, the second RA configuration information is used when a first condition is satisfied, the Msg3 is repeatedly transmitted in a second RA procedure according to the second RA configuration information, and K is a natural number.

A base station, comprising:
- a processor,
- wherein the processor causes the base station to:
- generate first random access (RA) configuration information;
- generate second RA configuration information used when a first condition is satisfied;
- transmit the first RA configuration information and the second RA configuration information to a terminal;
- receive a Msg1 from the terminal based on the second RA configuration information;
- transmit a Msg2, which is a response to the Msg1, to the terminal;
- and
- repeatedly receive a Msg3 K times from the terminal,
- wherein the Msg3 is not repeatedly transmitted in a first RA procedure according to the first RA configuration information, the Msg3 is repeatedly transmitted in a second RA procedure according to the second RA configuration information, and K is a natural number.
