RADIO COMMUNICATION SYSTEM, RADIO STATION, RADIO TERMINAL, COMMUNICATION CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

摘要

A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) performs, with the radio terminal (3), radio resource control for the first cell (10) and the second cell (20) in order to perform the carrier aggregation. At least one of the second radio station (2) and the radio terminal (3) is configured to transmit, to the first radio station (10), information about a problem occurring in a radio link in the second cell (20) between the second radio station (20) and the radio terminal (30) while the carrier aggregation of the first cell (10) and the second cell (20) is being performed.

1. A radio communication system comprising:
a first radio station that serves a first cell; a second radio station that serves a second cell; and a radio terminal capable of performing carrier aggregation of the first and second cells, wherein the first radio station is configured to perform, with the radio terminal, radio resource control for the first and second cells in order to perform the carrier aggregation, and at least one of the second radio station and the radio terminal is configured to transmit, to the first radio station, information about a radio link problem occurring in a radio link in the second cell between the second radio station and the radio terminal while the carrier aggregation is being performed.
