Of course, other * procedures are possible, and may work better for particular environments. * * * FILLING THE RATE TABLE * * Given a particular initial rate and mode, as determined by the rate * scaling algorithm described below, the Linux driver uses the following * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the * Link Quality command: * * * 1) If using High-throughput (HT) (SISO or MIMO) initial rate: * a) Use this same initial rate for first 3 entries. * b) Find next lower available rate using same mode (SISO or MIMO), * use for next 3 entries. If no lower rate available, switch to * legacy mode (no HT40 channel, no MIMO, no short guard interval). * c) If using MIMO, set command's mimo_delimiter to number of entries * using MIMO (3 or 6). * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, * no MIMO, no short guard interval), at the next lower bit rate * (e.g. if second HT bit rate was 54, try 48 legacy), and follow * legacy procedure for remaining table entries. * * 2) If using legacy initial rate: * a) Use the initial rate for only one entry. * b) For each following entry, reduce the rate to next lower available * rate, until reaching the lowest available rate. * c) When reducing rate, also switch antenna selection. * d) Once lowest available rate is reached, repeat this rate until * rate table is filled (16 entries), switching antenna each entry. * * * ACCUMULATING HISTORY * * The rate scaling algorithm for agn devices, as implemented in Linux driver, * uses two sets of frame Tx success history: One for the current/active * modulation mode, and one for a speculative/search mode that is being * attempted. If the speculative mode turns out to be more effective (i.e. * actual transfer rate is better), then the driver continues to use the * speculative mode as the new current active mode. * * Each history set contains, separately for each possible rate, data for a * sliding window of the 62 most recent tx attempts at that rate. The data * includes a shifting bitmap of success(1)/failure(0), and sums of successful * and attempted frames, from which the driver can additionally calculate a * success ratio (success / attempted) and number of failures * (attempted - success), and control the size of the window (attempted). * The driver uses the bit map to remove successes from the success sum, as * the oldest tx attempts fall out of the window. * * When the agn device makes multiple tx attempts for a given frame, each * attempt might be at a different rate, and have different modulation * characteristics (e.g. antenna, fat channel, short guard interval), as set * up in the rate scaling table in the Link Quality command. The driver must * determine which rate table entry was used for each tx attempt, to determine * which rate-specific history to update, and record only those attempts that * match the modulation characteristics of the history set. * * When using block-ack (aggregation), all frames are transmitted at the same * rate, since there is no per-attempt acknowledgment from the destination * station. The Tx response struct iwl_tx_resp indicates the Tx rate in * rate_n_flags field. After receiving a block-ack, the driver can update * history for the entire block all at once. * * * FINDING BEST STARTING RATE: * * When working with a selected initial modulation mode (see below), the * driver attempts to find a best initial rate. The initial rate is the * first entry in the Link Quality command's rate table. * * 1) Calculate actual throughput (success ratio * expected throughput, see * table below) for current initial rate. Do this only if enough frames * have been attempted to make the value meaningful: at least 6 failed * tx attempts, or at least 8 successes. If not enough, don't try rate * scaling yet. * * 2) Find available rates adjacent to current initial rate. Available means: * a) supported by hardware && * b) supported by association && * c) within any constraints selected by user * * 3) Gather measured throughputs for adjacent rates. These might not have * enough history to calculate a throughput. That's okay, we might try * using one of them anyway! * * 4) Try decreasing rate if, for current rate: * a) success ratio is < 15% || * b) lower adjacent rate has better measured throughput || * c) higher adjacent rate has worse throughput, and lower is unmeasured * * As a sanity check, if decrease was determined above, leave rate * unchanged if: * a) lower rate unavailable * b) success ratio at current rate > 85% (very good) * c) current measured throughput is better than expected throughput * of lower rate (under perfect 100% tx conditions, see table below) * * 5) Try increasing rate if, for current rate: * a) success ratio is < 15% || * b) both adjacent rates' throughputs are unmeasured (try it!) || * b) higher adjacent rate has better measured throughput || * c) lower adjacent rate has worse throughput, and higher is unmeasured * * As a sanity check, if increase was determined above, leave rate * unchanged if: * a) success ratio at current rate < 70%. This is not particularly * good performance; higher rate is sure to have poorer success. * * 6) Re-evaluate the rate after each tx frame. If working with block- * acknowledge, history and statistics may be calculated for the entire * block (including prior history that fits within the history windows), * before re-evaluation. * * FINDING BEST STARTING MODULATION MODE: * * After working with a modulation mode for a "while" (and doing rate scaling), * the driver searches for a new initial mode in an attempt to improve * throughput. The "while" is measured by numbers of attempted frames: * * For legacy mode, search for new mode after: * 480 successful frames, or 160 failed frames * For high-throughput modes (SISO or MIMO), search for new mode after: * 4500 successful frames, or 400 failed frames * * Mode switch possibilities are (3 for each mode): * * For legacy: * Change antenna, try SISO (if HT association), try MIMO (if HT association) * For SISO: * Change antenna, try MIMO, try shortened guard interval (SGI) * For MIMO: * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) * * When trying a new mode, use the same bit rate as the old/current mode when * trying antenna switches and shortened guard interval. When switching to * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate * for which the expected throughput (under perfect conditions) is about the * same or slightly better than the actual measured throughput delivered by * the old/current mode. * * Actual throughput can be estimated by multiplying the expected throughput * by the success ratio (successful / attempted tx frames). Frame size is * not considered in this calculation; it assumes that frame size will average * out to be fairly consistent over several samples. The following are * metric values for expected throughput assuming 100% success ratio. * Only G band has support for CCK rates: * * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 * * G: 7 13 35 58 40 57 72 98 121 154 177 186 186 * A: 0 0 0 0 40 57 72 98 121 154 177 186 186 * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 * * After the new mode has been tried for a short while (minimum of 6 failed * frames or 8 successful frames), compare success ratio and actual throughput * estimate of the new mode with the old.

This time is controlled by * quiet_time, and the number of received packets below which a channel is * considered "quiet" is controlled by quiet_plcp_threshold. * * For active scanning on channels that have regulatory restrictions against * blindly transmitting, the scan can listen before transmitting, to make sure * that there is already legitimate activity on the channel.

False alarms are signals that the * Rx DSP tries to lock onto, but then discards after determining that they * are noise. * * The optimum number of false alarms is between 5 and 50 per 200 TUs * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e. * time listening, not transmitting). Driver must adjust sensitivity so that * the ratio of actual false alarms to actual Rx time falls within this range. * * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each * received beacon. These provide information to the driver to analyze the * sensitivity. Don't analyze statistics that come in from scanning, or any * other non-associated-network source.

Used for establishing a level * below which the device does not detect signals. * * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB) * Measure of background noise in silent period after beacon. * * channel_load * uSecs of actual Rx time during beacon period (varies according to * how much time was spent transmitting). * * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately: * * false_alarm_cnt * Signal locks abandoned early (before phy-level header). * * plcp_err * Signal locks abandoned late (during phy-level header). * * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from * beacon to beacon, i.e. each value is an accumulation of all errors * before and including the latest beacon. Values will wrap around to 0 * after counting up to 2^32 - 1. Driver must differentiate vs. * previous beacon's values to determine # false alarms in the current * beacon period. * * Total number of false alarms = false_alarms + plcp_errs * * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd * (notice that the start points for OFDM are at or close to settings for * maximum sensitivity): * * START / MIN / MAX * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120 * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210 * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140 * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270 * * If actual rate of OFDM false alarms (+ plcp_errors) is too high * (greater than 50 for each 204.8 msecs listening), reduce sensitivity * by *adding* 1 to all 4 of the table entries above, up to the max for * each entry. Conversely, if false alarm rate is too low (less than 5 * for each 204.8 msecs listening), *subtract* 1 from each entry to * increase sensitivity. * * For CCK sensitivity, keep track of the following: * * 1). 20-beacon history of maximum background noise, indicated by * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the * 3 receivers. For any given beacon, the "silence reference" is * the maximum of last 60 samples (20 beacons * 3 receivers). * * 2). 10-beacon history of strongest signal level, as indicated * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers, * i.e. the strength of the signal through the best receiver at the * moment. These measurements are "upside down", with lower values * for stronger signals, so max energy will be *minimum* value. * * Then for any given beacon, the driver must determine the *weakest* * of the strongest signals; this is the minimum level that needs to be * successfully detected, when using the best receiver at the moment. * "Max cck energy" is the maximum (higher value means lower energy!) * of the last 10 minima. Once this is determined, driver must add * a little margin by adding "6" to it. * * 3). Number of consecutive beacon periods with too few false alarms. * Reset this to 0 at the first beacon period that falls within the * "good" range (5 to 50 false alarms per 204.8 milliseconds rx). * * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd * (notice that the start points for CCK are at maximum sensitivity): * * START / MIN / MAX * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200 * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400 * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100 * * If actual rate of CCK false alarms (+ plcp_errors) is too high * (greater than 50 for each 204.8 msecs listening), method for reducing * sensitivity is: * * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX, * up to max 400. * * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160, * sensitivity has been reduced a significant amount; bring it up to * a moderate 161.

Otherwise (if gain has been significantly reduced), * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value. * * b) Save a snapshot of the "silence reference". * * If actual rate of CCK false alarms (+ plcp_errors) is too low * (less than 5 for each 204.8 msecs listening), method for increasing * sensitivity is used only if: * * 1a) Previous beacon did not have too many false alarms * 1b) AND difference between previous "silence reference" and current * "silence reference" (prev - current) is 2 or more, * OR 2) 100 or more consecutive beacon periods have had rate of * less than 5 false alarms per 204.8 milliseconds rx time. * * Method for increasing sensitivity: * * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX, * down to min 125. * * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX, * down to min 200. * * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100. * * If actual rate of CCK false alarms (+ plcp_errors) is within good range * (between 5 and 50 for each 204.8 msecs listening): * * 1) Save a snapshot of the silence reference. * * 2) If previous beacon had too many CCK false alarms (+ plcp_errors), * give some extra margin to energy threshold by *subtracting* 8 * from value in HD_MIN_ENERGY_CCK_DET_INDEX. * * For all cases (too few, too many, good range), make sure that the CCK * detection threshold (energy) is below the energy level for robust * detection over the past 10 beacon periods, the "Max cck energy". * Lower values mean higher energy;
