Patent ID: 8681686

Claim:
A terminal apparatus in a radio communication system in which a plurality of relay apparatuses relay communication between a base station apparatus and terminal apparatuses using the same frequency, on a per-subframe basis where each subframe includes a first period and a second period for communication between the plurality of relay apparatuses and a third period for communication between the plurality of relay apparatuses and the terminal apparatuses, while two adjacent relay apparatuses among the plurality of relay apparatuses perform transmission processing in mutually-different periods, respectively, in the first period and the second period, and the plurality of relay apparatuses simultaneously perform transmission to terminal apparatuses connected to the relay apparatuses, in the third period, the terminal apparatus comprising: a selection section that selects connection to an upstream relay apparatus positioned upstream in a signal transfer direction between the base station apparatus and the terminal apparatus from among the two relay apparatuses, when the terminal apparatus is connectable to the two relay apparatuses; a receiving section that receives a signal for another terminal apparatus, the signal being transmitted from the upstream relay apparatus to a downstream relay apparatus positioned downstream in the transfer direction among the two relay apparatuses, in the first period or the second period; and a removing section that removes a signal for the other terminal apparatus transmitted from the downstream relay apparatus in the third period from a signal received in the third period, using the signal for the other terminal apparatus received in the first period or the second period, thereby obtaining a signal for the terminal apparatus transmitted from the upstream relay apparatus.
