can anyone tell me what is the difference between ARQ & HARQ Thanks in advance —Preceding unsigned comment added by 203.199.255.131 (talk • contribs) 13:05, 2 May 2007 (UTC)[reply]

My understanding is that ARQ refers to the basic strategy of retransmitting data packets in the event of a decoding error at the receiver. Hybrid-ARQ necessarily implies the presence of forward error correction (FEC) in these data packets; thus, the rate decreases, but throughput should increase as a result of applying coding. Hybrid-ARQ allows for various FEC encoding and decoding strategies (such as Chase combining and incremental redundancy). Flashantenna 17:46, 12 September 2007 (UTC)[reply]

According to WP naming conventions, spelled out words should be preferred over abbreviations, unless the topic is known almost exclusively by its abbreviation and is widely known and used in that form. --Pgan002 11:06, 24 July 2007 (UTC)[reply]

• Conditionally concur, per article naming conventions, but is this actually the correct term? Suspicious because it is a redlink; why doesn't it at least redir to Hybrid ARQ? — SMcCandlish [talk] [cont] ‹(-¿-)› 22:45, 25 July 2007 (UTC)[reply]
  • Yes, except perhaps for the hyphen. It is a variation of ARQ, and ARQ stands for "automatic repeat-request". I confirmed this by reading Soljanin E., "Hybrid ARQ in Wireless Networks", Advances in Network Information Theory, American Mathematical Society Publications, DIMACS Series in Discrete Mathematics and Theoretical Computer Science, vol. 66, Edited by: P. Gupta, G. Kramer, and A. J. van Wijngaarden, 2004. All sources I found in my short search use the name without hyphen: "automatic repeat request". So I change my proposal to rename the article to "Hybrid automatic repeat request". I will create a separate request for move for ARQ. -Pgan002 00:32, 28 July 2007 (UTC)[reply]

This article has been renamed from Hybrid ARQtoHybrid automatic repeat-request as the result of a move request. While I am aware that the request was changed to omit the hyphen, consistency requires it for now. --Stemonitis 18:23, 30 July 2007 (UTC)[reply]

There is no need for a separate entry with hyphen (Hybrid automatic repeat-request) that just redirects to the main page without hyphen (Hybrid automatic repeat request). I suggest that the redirect with hyphen be deleted. Isheden (talk) 14:41, 7 July 2010 (UTC)[reply]

The text implies that a separate code is used for the error correction and error detection. Is that really the case? A single code with a high Hamming distance can be used for both purposes simultaneously. LachlanA (talk) 08:32, 15 August 2011 (UTC)[reply]
