An electronic device, information processing apparatus, and information processing method. The electronic device at a base station side includes a processor circuit. The processor circuit is configured to acquire information related to a success rate of uplink transmission in an unlicensed frequency band of at least one user equipment unit, wherein the user equipment unit employs a channel detection process to perform carrier sensing on the unlicensed frequency band, and the channel detection process includes a random back-off process having a variable contention window size. The processor circuit is further configured to adjust, based on the information, the contention window size of the user equipment unit. The processor circuit is further configured to perform control, such that the user equipment unit is notified of the adjusted contention window size or a value of a random back-off counter generated on the basis of the adjusted contention window size.
