An adaptive HARQ algorithm in MIMO systems

2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009
Multi-input multi-output (MIMO) techniques are used to provide space multiplexing and improve point-to-point link capacity in wireless communication systems, but due to the deep fading in channel gain, large noise and co-channel interference, the data packets are likely not to be recovered correctly in receiver, thus hybrid automatic repeat request ...

On the Performance of HARQ with Hybrid Relaying Schemes

2009 IEEE International Conference on Communications, 2009
In this paper, we consider a three-node relay system with a hybrid relaying scheme, where the relay, based on its decoding status, switches between decode-and-forward (DF) and compress-and-forward (CF) adaptively. We propose according HARQ strategy and analyze its throughput performance.

Optimal HARQ procedures for reverse link

2004 IEEE 15th International Symposium on Personal, Indoor and Mobile Radio Communications (IEEE Cat. No.04TH8754), 2005
This paper presents optimal HARQ procedures for reverse link of next generation wireless communication systems. Different criteria are proposed for different classes of services, including the delay-intolerant ones. For delay-tolerant services the IR (incremental redundancy) gain is fully exploited and the gain brought by retransmissions are evident ...

Analysis of cooperative HARQ with opportunistic routing

2013 IEEE 14th Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2013
In this paper, we do performance analysis of the cooperative HARQ protocol in a wireless adhoc multihop network employing spatial ALOHA. We model the nodes in such a network by a homogeneous 2-D Poisson point process. We study the tradeoff between the transport capacity submetrics inherent in the network when using cooperative HARQ protocol and ...

Joint coding of sequential HARQ feedback

2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2016
Wireless broadband systems conceal the high error rates of their underlying channel from Internet protocols such as TCP using a windowed ARQ protocol. They also use a HARQ protocol at the physical layer where ACK/NACK feedback signals are sent for every packet. The higher layer “outer” ARQ protocol is needed due to the relatively high error rate of the
