On Power Allocation for Incremental Redundancy Hybrid ARQ

IEEE Transactions on Wireless Communications, 2015
We study the power allocation for incremental redundancy (IR) hybrid automatic repeat request (HARQ) in block fading channel where causal channel state information is known at both the transmitter and the receiver. In IR-HARQ, the traffic is assigned into consecutive transmission rounds, and at each round, the instantaneous mutual information that is ...

Optimization of Hybrid ARQ for IP Packet Transmission

Wireless Personal Communications, 2001
This paper presents, optimizes, and analyzes the performance of a novel hybrid Selective Repeat/Multi Copy (SR/MC) Automatic Repeat Request (ARQ) scheme for transmitting fragmented Internet Protocol (IP) packets. The ARQ scheme works in the SR mode until the last IP packet fragment is transmitted. If a fragment is negatively acknowledged after the last

Performance of hybrid ARQ schemes for the fading channel

IEEE Transactions on Communications, 2002
We define and adopt a theoretical method, based on the sphere-packing bound, for evaluating and comparing the achievable performance of different hybrid automatic repeat request schemes for the fading channel. The channel state evolution is assumed to be represented by a finite-state Markov chain.

Hybrid-ARQ with Rate Compatible LDPC Codes

2012
Recently various mobile communication systems such as IEEE 802.11n and IEEE802.16e have been growing interest in low parity check (LDPC) codes as a forward error correction codes. However, IR (incremental redundancy) hybrid ARQ scheme with LDPC codes has not been specified yet.
