Abstract: A system and method for relaying transmissions in wireless communications is provided. A method for combined relay node operation includes determining an operating mode of the combined relay node, where the combined relay node includes a repeater and a relay. The method also includes if the operating mode is repeater on mode, amplifying and forwarding received signals, and storing subframes, where subframes are demodulated and decoded versions of the received signals. The method further includes if the operating mode is repeater off mode, amplifying and forwarding a control zone of signals received while the operating mode is repeater off mode, and transmitting subframes stored while the operating mode is repeater on mode.

Abstract: A method and apparatus for interleaving within a communication system is provided herein. More particularly parameters for a convolutional turbo code interleaver are provided, and interleaving takes place utilizing the new parameters. The new parameters generate interleavers that have the correct turbo code behaviors of improving performance with increasing block size and an error floor well below a block error rate of 10−4. Furthermore, the parameters have no implementation impact. Interleaving in accordance with the preferred embodiment of the present invention can achieve a block error rate of 10−4 at a signal-to-noise ratio that is at least 0.5 dB, and in some cases up to 1.3 dB, smaller than that which can be achieved with the code using the existing parameters.
