    Abstract: An operation method of a terminal in a communication system may comprise: obtaining a plurality of serving beam measurement values by performing measurement on a plurality of serving beams; identifying a minimum measurement value among the plurality of serving beam measurement values; obtaining a plurality of beam measurement values by performing measurement on a plurality of beams received from a plurality of base stations included in the communication system; determining whether a first condition is satisfied, the first condition being defined based on a result of comparison between the plurality of beam measurement values and a sum of the minimum measurement value and a first offset; and in response to determining that the first condition satisfied, performing communication with at least part of the plurality of serving base stations and a first base station forming a first beam satisfying the first condition.

    IPC: H04W74/08

    Abstract: An operation method of a base station in a communication system may comprise: generating first RACH configuration information for a normal terminal; generating second RACH configuration information for a RedCap terminal; transmitting a message including the first RACH configuration information and the second RACH configuration information; and performing a random access procedure with a first terminal based on the message, wherein a terminal type of the first terminal is identified based on the first RACH configuration information and the second RACH configuration information, and the terminal type is the normal terminal or the RedCap terminal.

    Abstract: A method for operating a transmission node performing link adaptation in a mobile communication network may include the steps of: receiving, from a resource allocation node, resource allocation information for a resource for transmission of data; determining link adaptation information and transmitting the determined link adaptation information to a reception node; and on the basis of the determined link adaptation information, transmitting the data to the reception node. Therefore, link adaptation accurately reflecting a radio channel state between a base station and terminals can be performed, thereby enabling efficient use of a radio resource.
