If no lower rate available, switch to 2163 * legacy mode (no HT40 channel, no MIMO, no short guard interval). 2164 * c) If using MIMO, set command's mimo_delimiter to number of entries 2165 * using MIMO (3 or 6). 2166 * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, 2167 * no MIMO, no short guard interval), at the next lower bit rate 2168 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow 2169 * legacy procedure for remaining table entries. 2170 * 2171 * 2) If using legacy initial rate: 2172 * a) Use the initial rate for only one entry. 2173 * b) For each following entry, reduce the rate to next lower available 2174 * rate, until reaching the lowest available rate. 2175 * c) When reducing rate, also switch antenna selection. 2176 * d) Once lowest available rate is reached, repeat this rate until 2177 * rate table is filled (16 entries), switching antenna each entry. 2178 * 2179 * 2180 * ACCUMULATING HISTORY 2181 * 2182 * The rate scaling algorithm for 4965, as implemented in Linux driver, uses 2183 * two sets of frame Tx success history: One for the current/active modulation 2184 * mode, and one for a speculative/search mode that is being attempted. If the 2185 * speculative mode turns out to be more effective (i.e. actual transfer 2186 * rate is better), then the driver continues to use the speculative mode 2187 * as the new current active mode. 2188 * 2189 * Each history set contains, separately for each possible rate, data for a 2190 * sliding window of the 62 most recent tx attempts at that rate. The data 2191 * includes a shifting bitmap of success(1)/failure(0), and sums of successful 2192 * and attempted frames, from which the driver can additionally calculate a 2193 * success ratio (success / attempted) and number of failures 2194 * (attempted - success), and control the size of the window (attempted). 2195 * The driver uses the bit map to remove successes from the success sum, as 2196 * the oldest tx attempts fall out of the window. 2197 * 2198 * When the 4965 makes multiple tx attempts for a given frame, each attempt 2199 * might be at a different rate, and have different modulation characteristics 2200 * (e.g. antenna, fat channel, short guard interval), as set up in the rate 2201 * scaling table in the Link Quality command. The driver must determine 2202 * which rate table entry was used for each tx attempt, to determine which 2203 * rate-specific history to update, and record only those attempts that 2204 * match the modulation characteristics of the history set. 2205 * 2206 * When using block-ack (aggregation), all frames are transmitted at the same 2207 * rate, since there is no per-attempt acknowledgment from the destination 2208 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in 2209 * rate_n_flags field. After receiving a block-ack, the driver can update 2210 * history for the entire block all at once. 2211 * 2212 * 2213 * FINDING BEST STARTING RATE: 2214 * 2215 * When working with a selected initial modulation mode (see below), the 2216 * driver attempts to find a best initial rate. The initial rate is the 2217 * first entry in the Link Quality command's rate table. 2218 * 2219 * 1) Calculate actual throughput (success ratio * expected throughput, see 2220 * table below) for current initial rate. Do this only if enough frames 2221 * have been attempted to make the value meaningful: at least 6 failed 2222 * tx attempts, or at least 8 successes. If not enough, don't try rate 2223 * scaling yet. 2224 * 2225 * 2) Find available rates adjacent to current initial rate. Available means: 2226 * a) supported by hardware && 2227 * b) supported by association && 2228 * c) within any constraints selected by user 2229 * 2230 * 3) Gather measured throughputs for adjacent rates. These might not have 2231 * enough history to calculate a throughput. That's okay, we might try 2232 * using one of them anyway! 2233 * 2234 * 4) Try decreasing rate if, for current rate: 2235 * a) success ratio is < 15% || 2236 * b) lower adjacent rate has better measured throughput || 2237 * c) higher adjacent rate has worse throughput, and lower is unmeasured 2238 * 2239 * As a sanity check, if decrease was determined above, leave rate 2240 * unchanged if: 2241 * a) lower rate unavailable 2242 * b) success ratio at current rate > 85% (very good) 2243 * c) current measured throughput is better than expected throughput 2244 * of lower rate (under perfect 100% tx conditions, see table below) 2245 * 2246 * 5) Try increasing rate if, for current rate: 2247 * a) success ratio is < 15% || 2248 * b) both adjacent rates' throughputs are unmeasured (try it!) || 2249 * b) higher adjacent rate has better measured throughput || 2250 * c) lower adjacent rate has worse throughput, and higher is unmeasured 2251 * 2252 * As a sanity check, if increase was determined above, leave rate 2253 * unchanged if: 2254 * a) success ratio at current rate < 70%. This is not particularly 2255 * good performance; higher rate is sure to have poorer success. 2256 * 2257 * 6) Re-evaluate the rate after each tx frame. If working with block- 2258 * acknowledge, history and statistics may be calculated for the entire 2259 * block (including prior history that fits within the history windows), 2260 * before re-evaluation. 2261 * 2262 * FINDING BEST STARTING MODULATION MODE: 2263 * 2264 * After working with a modulation mode for a "while" (and doing rate scaling), 2265 * the driver searches for a new initial mode in an attempt to improve 2266 * throughput. The "while" is measured by numbers of attempted frames: 2267 * 2268 * For legacy mode, search for new mode after: 2269 * 480 successful frames, or 160 failed frames 2270 * For high-throughput modes (SISO or MIMO), search for new mode after: 2271 * 4500 successful frames, or 400 failed frames 2272 * 2273 * Mode switch possibilities are (3 for each mode): 2274 * 2275 * For legacy: 2276 * Change antenna, try SISO (if HT association), try MIMO (if HT association) 2277 * For SISO: 2278 * Change antenna, try MIMO, try shortened guard interval (SGI) 2279 * For MIMO: 2280 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) 2281 * 2282 * When trying a new mode, use the same bit rate as the old/current mode when 2283 * trying antenna switches and shortened guard interval. When switching to 2284 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate 2285 * for which the expected throughput (under perfect conditions) is about the 2286 * same or slightly better than the actual measured throughput delivered by 2287 * the old/current mode. 2288 * 2289 * Actual throughput can be estimated by multiplying the expected throughput 2290 * by the success ratio (successful / attempted tx frames).
