Abstract: A method and apparatus for NSTR communication in a communication system supporting multiple links are disclosed. A method for a first device comprises the steps of: if a first backoff operation has succeeded on a first link belonging to a first pair of NSTR links on which an STR operation of a second device is not supported, transmitting a first data frame to the second device on the first link; performing a second backoff operation for transmission of a second data frame on a second link belonging to the first pair of NSTR links; if the second backoff operation has succeeded on the second link, identifying whether or not a transmission operation of the second device is performed on the first link belonging to the pair of NSTR links; and transmitting the second data frame to the second device on the second link.

Abstract: A power control method for reducing power consumption of a terminal during retransmission in a wireless communication system using spread spectrum may include: transmitting a response message corresponding to a request message received from a base station to the base station; determining whether an acknowledgement (ACK) message is received from the base station in response to the response message; after the ACK message is received, determining whether the response message is decoded by the base station on the basis of the ACK message; and when it is determined that the response message is not decoded by the base station, setting retransmission transmission power randomly.
