1. A wireless relay system including a plurality of terminal station apparatuses and a base station apparatus configured to relay data traffic transmitted through wireless communication between the plurality of terminal station apparatuses, wherein the base station apparatus includes:
a processor; and
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
receive pieces of upstream data traffic from the plurality of terminal station apparatuses; if the pieces of upstream data traffic that require mutual forwarding in opposing directions between the plurality of terminal station apparatuses are present in the respective pieces of upstream data traffic, perform network encoding on the respective pieces of upstream data traffic such that the pieces of upstream data traffic are pieces of data traffic of mutually identical content; and simultaneously transmit pieces of encoded data traffic indicating the pieces of data traffic subjected to network encoding as downstream data traffic to the plurality of terminal station apparatuses that transmitted the pieces of upstream data traffic, and
wherein the terminal station apparatuses each include:
a processor; and
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
transmit the upstream data traffic to the base station apparatus; receive the pieces of encoded data traffic transmitted from the base station apparatus; and decode the pieces of encoded data traffic using the upstream data traffic.
