A method of a relay node transmitting data is provided. The method includes receiving scheduling information about a backhaul link and data from a base station; receiving channel information about an access link from relay node user equipment; performing scheduling on the access link based on the scheduling information about the backhaul link and the channel information about the access link; and relaying the data to the relay node user equipment according to a result of the scheduling. The backhaul link means a link between the base station and the relay node, and the access link means a link between the relay node and the relay node user equipment.

Relay station data transmission method

A fixed multiply-add (FMA) apparatus and method are provided. The FMA apparatus includes a partial product generator configured to generate a partial sum and a partial carry, a carry save adder configured to generate a partial sum having a first bit size and a partial carry having the first bit size by adding the partial sum and the partial carry to least significant bits (LSBs) of the mantissa of a third floating-point number, a carry select adder configured to generate a mantissa having a second bit size by adding the first bit-size partial sum and the first bit-size partial carry to most significant bits (MSBs) of the third floating-point number, and a selector configured to transmit the first bit-size partial sum and the first bit-size partial carry to the carry save adder or the carry select adder according to whether the mantissa of the third floating-point number is zero.
