description

Write or compress an IEEE communications LETTER for WCL (IEEE Wireless Communications Letters) or CL (IEEE Communications Letters): a single-contribution paper with a compressed introduction, no standalone related-work section, one system model, one core result (an algorithm OR a closed-form expression), and a tight simulation section under the current WCL/CL page budget. Use this whenever the target is a letter rather than a transactions paper — "write a WCL letter", "turn this into a letter", "我的论文要投WCL/CL", "压缩成letter", "写一篇通信快报", "letter写不下了怎么删", "cut my letter to fit", EDICS selection, and the WCL/CL submission checklist. For full transactions papers (JSAC/TWC/TCOM) use ieee-writing; for the results narrative use ieee-writing + ieee-experiments; for figures use ieee-figure. Bilingual: turns Chinese notes into a submission-ready English letter plus short Chinese explanations.

IEEE Communications Letter (WCL / CL)

A letter is not a short transactions paper. It is a single, sharp contribution presented under a tight page budget (currently a 5-page maximum for both WCL and CL, with page charges beyond the free page budget under ComSoc guidance). The job is to make one result land — fast — and to cut everything that does not serve it. Use this skill to draft a letter from scratch or to compress an over-length draft.

Core stance

• One contribution, stated once. A letter carries a single advance: one algorithm, one closed-form expression, one new scheme, or one decisive finding. If the draft has two, it is a transactions paper — say so and use ieee-writing.
• The free-page budget is a design constraint, not a trim at the end. Plan the budget before drafting (see page budget below). Treat a paid fifth page as a strategic decision for essential evidence, not as permission to write a small transaction.
• No standalone Related Work section. Prior work is folded into the Introduction as the gap.
• Author evidence comes first. Never invent results, numbers, channel models, benchmark schemes, or limitations. Missing evidence → [PLACEHOLDER: ...] or ask the user.
• Same IEEE register as a transactions paper: US English, numbered citations [n], bold-vector / bold-matrix notation, equations numbered only for the skeleton of the argument.

WCL vs CL — know the target

	IEEE WCL (Wireless Comms Letters)	IEEE CL (Communications Letters)
Page limit	Currently 5 pages maximum; the 5th page incurs an over-length charge	Currently 5 pages maximum; pages beyond 4 incur over-length charges
Abstract	Short letter abstract, commonly 75–100 words	Short letter abstract, commonly 75–100 words
EDICS	not required	required at submission
Scope	wireless / PHY-MAC	all communications
Anonymity	single-blind (default)	double-anonymous option available
Figures	submit vector (EPS/PDF)	submit vector (EPS/PDF)

Always confirm the current page/fee/EDICS rules in the journal's author kit before submitting; these defaults change. If the user has not named WCL vs CL, ask — the EDICS and anonymity rules differ.

Page budget (IEEEtran, two-column, 10pt) — plan this first

Aim for the free 4-page budget by default. Use the paid fifth page only when it protects the one contribution's proof, experiment, or critical validation.

Title + abstract + Index Terms              ~0.25 page
I.  Introduction (gap + contribution)       ~0.75 page
II. System Model (+ problem if needed)      ~1.0 page
III. Proposed Scheme / Analysis (core)      ~1.0 page
IV. Simulation Results (2–4 figures/tables) ~0.75 page
V.  Conclusion (3–4 sentences) + refs       ~0.25 page

This is a starting allocation, not a rule. The core (III) and the result (IV) are the paper; protect their space and compress I–II. Verify how references and appendices count in the target journal's current Author Kit.

When to open extra files

File	Open when
references/letter-format.md	Drafting the letter section by section, or deciding what a letter keeps vs. what only a transactions paper carries
references/compression-tactics.md	An existing draft exceeds the free budget or the 5-page maximum and must be cut without losing the argument; or fitting figures/tables/equations into the budget

For the argument of each section, defer to ieee-writing (its section defaults apply, compressed). For simulation content use ieee-experiments; for figures use ieee-figure; for references and EDICS use ieee-citation; for the cover/response letters use ieee-response.

Intake — establish before drafting

• target: WCL or CL (they differ on EDICS and anonymity)
• the one contribution: in a single sentence — the advance the letter exists to deliver
• type: algorithm/design letter, or closed-form analysis letter (changes Section III)
• evidence: the algorithm + convergence, or the derivation + a simulation overlay
• boundary: the CSI/channel assumption and scope where the claim holds
• starting point: drafting fresh, or compressing an over-length draft (→ compression-tactics.md)

If "the one contribution" is actually two, flag it: a letter cannot carry both well.

Drafting workflow

1. One-sentence contribution. We propose/derive [the one advance] for [system], which [benefit], under [boundary]. Confirm it with the user.
2. Check it fits a letter. One contribution, one model, one core result. If not, route to ieee-writing.
3. Allocate the page budget (above), then draft core-first: Section III, then IV, then the compressed Introduction, then System Model, then Abstract and Conclusion last.
4. Draft from evidence outward; keep each claim beside its support. Use ieee-writing section logic, compressed: Introduction ends with a short contribution statement (often 1–2 sentences, not a numbered list of four).
5. Fit the figures: 2–4 decisive figures/tables maximum, vector (EPS/PDF), readable at column width — see ieee-figure. One should validate analysis (line + Monte-Carlo markers) if the letter derives an expression.
6. Page-fit pass: if over the free budget, decide whether the paid fifth page is justified; if over the maximum, apply references/compression-tactics.md in order (cut repetition and over-fine detail before touching the core result).
7. Return the letter (LaTeX if IEEEtran), a page-budget estimate, a claim–evidence map, and a note on what was cut to fit.

Letter-specific section defaults

• Abstract: ~75–100 words unless the current Author Kit says otherwise, one quantified headline.
• Introduction: compress to gap → contribution. Fold prior work into the gap; no separate Related Work. End with a one- or two-sentence contribution statement, not a 4-item list.
• System Model: only the symbols the core result needs. Cut generality the result does not use.
• Proposed Scheme / Analysis (the core): the algorithm box or the theorem/derivation — the one thing the letter exists for. Label transformations exact vs approximate; state convergence target (KKT/stationary/global) honestly. Long proofs are usually cut or sketched, not appended (letters rarely have appendices — confirm with the author kit).
• Simulation Results: 2–4 decisive figures/tables, claim-first. Validate the derived expression first if there is one; then the single most important comparison vs benchmark schemes. A compact measurement/testbed result is worth the space only if it supports the one contribution. State the fairness boundary in one sentence.
• Conclusion: 3–4 sentences. Contribution → decisive result → boundary/outlook. No new data.

Output format

1. Draft: the letter prose (or IEEEtran LaTeX).
2. Page budget: estimated pages per section vs. the free-page budget and the 5-page maximum.
3. Claim–evidence map: Claim … | Evidence … | Status: supported / needs evidence.
4. Cut list: what was removed (or must be) to fit, and what was protected.
5. Assumptions or missing inputs: only material issues.

For Chinese input, give the polished English letter first, then brief Chinese notes on what was compressed or cut and why.
