In addition to these attributes, when the relay decides to retransmit [21], it may do it by providing the destination user with a repeated message (as in HARQ type I, chase combining) or with a re-encoded message [11][12][13] (as in HARQ type II, code combining). In both cases, the retransmission may effectively be considered a reconfigurable scheme that accommodates different error protection capabilities (enhancing the transmission rate) depending on the channel state.…”

Abstract.-Cooperative transmission can be seen as a "virtual" MIMO system, where the multiple transmit antennas are in fact implemented distributed by the antennas both at the source and the relay terminal. Depending on the system design, diversity/multiplexing gains are achievable. This design involves the definition of the type of retransmission (incremental redundancy, repetition coding), the design of the distributed space-time codes, the error correcting scheme, the operation of the relay (decode&forward or amplify&forward) and the number of antennas at each terminal. Proposed schemes are evaluated in different conditions in combination with forward error correcting codes (FEC), both for linear and near-optimum (sphere decoder) receivers, for its possible implementation in downlink high speed packet services of cellular networks. Results show the benefits of coded cooperation over direct transmission in terms of increased throughput. It is shown that multiplexing gains are observed even if the mobile station features a single antenna, provided that cell wide reuse of the relay radio resource is possible.

“…In data communication systems, Automatic Repeat reQuest (ARQ) schemes are adopted to guarantee the reliable delivery of the transmitted packets in the presence of errors (Costello et al 1998). ARQ schemes allow erroneous data to be retransmitted according to three major ARQ schemes: Stop-and-wait, Go-back-N and Selective Repeat (Kurose and Ross 2002).…”

Abstract-Network coding (NC) has been an attractive research topic in recent years as a means of offering a throughput improvement, especially in multicast scenarios. The throughput gain is achieved by introducing an algebraic method for combining multiple input streams of packets which are addressing one output port at an intermediate node. We present a practical implementation of network coding in conjunction with error control schemes, namely the Stop-and-Wait (SW) and Selective Repeat (SR) protocols. We propose a modified NC scheme and apply it at an intermediate SW ARQ-based link to reduce ARQ control signals at each transmission. We further extend this work to investigate the usefulness of NC in the Butterfly multicast network which adopts the SR ARQ protocol as an error control scheme. We validate our throughput analysis using a relatively recent discrete-event simulator, SimEvents ® . The results show that the proposed scheme offers a throughput advantage of at least 50% over traditional SW ARQ, and that this is particularly noticeable in the presence of high error rates. In the multicast network, however, simulation results show that when compared with the traditional scheme, NC-SR ARQ can achieve a throughput gain of between 2% and 96% in a low bandwidth channel and up to 19% in a high bandwidth channel with errors.

“…This ARQ protocol introduced in [11] follows the transmission depicted in Fig.1 and it outlines the benefits of using different assisting relays in each retransmission through a numerical evaluation of the throughput for a given data rate. Likewise, the situation where source and relay transmits simultaneously in phase II is analyzed in [12] from a multiplexing-diversity-delay tradeoff point of view, using an incremental redundancy Hybrid ARQ.The present work envisions the pure-ARQ, [10], when onlysource or source-and-relay manage the retransmission procedure, in contrast to [7]. Moreover, unlike [11] and [9], the transmission rate and times of phase I and phase II are optimized to maximize the throughput.…”

Abstract-Automatic repeat request (ARQ) protocols deal with the situations where the selected data rate is not supported by the current channel realization. The inappropriate selection is motivated by the limited channel state information at the transmitter (CSIT). This work looks into how the ARQ protocols are applied to the half-duplex relay-assisted transmission with decode-and-forward relays by exploiting the ACK feedback channel of the terminals. Two implementations are tackled: 1) only the source or 2) source and relay manage the retransmissions under the pure-ARQ protocol. This work presents an analytical framework for the comparison of both options. The study allows the optimization of the bitrate and amount of resource allocated for the relay transmission phases. Index Terms-ARQ, relay, cooperative system I. INTRODUCTIONRelay-assisted has become an effective tool for combating the effects of propagation channel in wireless networks thanks to the relay terminal. Originally proposed in [1] with capacity results proved in [2], it has regained attention due to the diversity gain obtained in wireless channels, [3], [4], [5]. This work assumes half-duplex relays under decode-and-forward (DF), [4]. Hence, the transmission is carried out through two orthogonal phases: relay-receive phase (or phase I) and relaytransmit phase (or phase II).Among the many existing relay protocols [6], we have selected the relay-assisted transmission described by Fig. 1. In phase I the source transmits to the relay and destination. Afterwards, only the relay transmits to the destination. This is the same procedure used in [4] and named protocol I in [6]. The relay may transmit under repetition coding, RC, (using the same codeword as the source) or unconstrained coding, UC, (employing a different codebook from the source), [8].The exploitation of the ACK feedback channels from the terminals allows implementing the relay-assisted transmission procedure in different ways. For instance, if the source is in charge of the Automatic Repeat reQuest (ARQ) procedure and the source uses only the requests from destination, the retransmission is repeated along phase I and phase II. If the relay feedbacks to the source its success (ACK/NACK) in decoding the message, then the source might transmit during phase II, remaining the relay silent. Similarly, an ARQ protocol proposed in [9] enforces the use of the relay only when it receives successfully in phase I of the first transmission, also with ACKs from relay and destination. That analysis is carried out for the pure-ARQ protocol [10] with adaptive modulation. Moreover, the optimal bitrate and resource allocation is addressed in [7], where the source manages the ARQ with ACKs only from destination. When source and relay control the ARQ procedure, the source receives the feedback from the relay and destination while the relay listens the feedback from destination (ACKs from relay and destination). In such a case, the source transmits till either the relay or destination decodes the message. Once ...
