Claim of US Patent No. 10,368,380

1. A user equipment included in a wireless communication system, wherein the user equipment wirelessly accesses a mobile relay to establish an access link, wirelessly accesses a donor base-station to establish a macro link, simultaneously maintains connections with the donor base-station and the mobile relay coexisting in the same coverage area, and conducts wireless communication with the mobile relay through the access link using a pre-established first frequency band and conducts wireless communication with the donor base-station through the macro link using a pre-established second frequency band,wherein a data transmission mode used for the access link is a time division duplex mode,
the data transmission mode used for the macro link is a frequency division duplex mode, and
the user equipment dynamically changes a resource assignment ratio for each of uplink and downlink through the access link according to predetermined conditions of change and transmits change information of the resource assignment ratio to the mobile relay, and
the change information of the resource assignment ratio is used in changing a resource assignment ratio of another user equipment within a coverage of the mobile relay as the conditions of change.
