If no lower rate available, switch to 1676 * legacy mode (no HT40 channel, no MIMO, no short guard interval). 1677 * c) If using MIMO, set command's mimo_delimiter to number of entries 1678 * using MIMO (3 or 6). 1679 * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, 1680 * no MIMO, no short guard interval), at the next lower bit rate 1681 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow 1682 * legacy procedure for remaining table entries. 1683 * 1684 * 2) If using legacy initial rate: 1685 * a) Use the initial rate for only one entry. 1686 * b) For each following entry, reduce the rate to next lower available 1687 * rate, until reaching the lowest available rate. 1688 * c) When reducing rate, also switch antenna selection. 1689 * d) Once lowest available rate is reached, repeat this rate until 1690 * rate table is filled (16 entries), switching antenna each entry. 1691 * 1692 * 1693 * ACCUMULATING HISTORY 1694 * 1695 * The rate scaling algorithm for agn devices, as implemented in Linux driver, 1696 * uses two sets of frame Tx success history: One for the current/active 1697 * modulation mode, and one for a speculative/search mode that is being 1698 * attempted. If the speculative mode turns out to be more effective (i.e. 1699 * actual transfer rate is better), then the driver continues to use the 1700 * speculative mode as the new current active mode. 1701 * 1702 * Each history set contains, separately for each possible rate, data for a 1703 * sliding window of the 62 most recent tx attempts at that rate. The data 1704 * includes a shifting bitmap of success(1)/failure(0), and sums of successful 1705 * and attempted frames, from which the driver can additionally calculate a 1706 * success ratio (success / attempted) and number of failures 1707 * (attempted - success), and control the size of the window (attempted). 1708 * The driver uses the bit map to remove successes from the success sum, as 1709 * the oldest tx attempts fall out of the window. 1710 * 1711 * When the agn device makes multiple tx attempts for a given frame, each 1712 * attempt might be at a different rate, and have different modulation 1713 * characteristics (e.g. antenna, fat channel, short guard interval), as set 1714 * up in the rate scaling table in the Link Quality command. The driver must 1715 * determine which rate table entry was used for each tx attempt, to determine 1716 * which rate-specific history to update, and record only those attempts that 1717 * match the modulation characteristics of the history set. 1718 * 1719 * When using block-ack (aggregation), all frames are transmitted at the same 1720 * rate, since there is no per-attempt acknowledgment from the destination 1721 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in 1722 * rate_n_flags field. After receiving a block-ack, the driver can update 1723 * history for the entire block all at once. 1724 * 1725 * 1726 * FINDING BEST STARTING RATE: 1727 * 1728 * When working with a selected initial modulation mode (see below), the 1729 * driver attempts to find a best initial rate. The initial rate is the 1730 * first entry in the Link Quality command's rate table. 1731 * 1732 * 1) Calculate actual throughput (success ratio * expected throughput, see 1733 * table below) for current initial rate. Do this only if enough frames 1734 * have been attempted to make the value meaningful: at least 6 failed 1735 * tx attempts, or at least 8 successes. If not enough, don't try rate 1736 * scaling yet. 1737 * 1738 * 2) Find available rates adjacent to current initial rate. Available means: 1739 * a) supported by hardware && 1740 * b) supported by association && 1741 * c) within any constraints selected by user 1742 * 1743 * 3) Gather measured throughputs for adjacent rates. These might not have 1744 * enough history to calculate a throughput. That's okay, we might try 1745 * using one of them anyway! 1746 * 1747 * 4) Try decreasing rate if, for current rate: 1748 * a) success ratio is < 15% || 1749 * b) lower adjacent rate has better measured throughput || 1750 * c) higher adjacent rate has worse throughput, and lower is unmeasured 1751 * 1752 * As a sanity check, if decrease was determined above, leave rate 1753 * unchanged if: 1754 * a) lower rate unavailable 1755 * b) success ratio at current rate > 85% (very good) 1756 * c) current measured throughput is better than expected throughput 1757 * of lower rate (under perfect 100% tx conditions, see table below) 1758 * 1759 * 5) Try increasing rate if, for current rate: 1760 * a) success ratio is < 15% || 1761 * b) both adjacent rates' throughputs are unmeasured (try it!) || 1762 * b) higher adjacent rate has better measured throughput || 1763 * c) lower adjacent rate has worse throughput, and higher is unmeasured 1764 * 1765 * As a sanity check, if increase was determined above, leave rate 1766 * unchanged if: 1767 * a) success ratio at current rate < 70%. This is not particularly 1768 * good performance; higher rate is sure to have poorer success. 1769 * 1770 * 6) Re-evaluate the rate after each tx frame. If working with block- 1771 * acknowledge, history and statistics may be calculated for the entire 1772 * block (including prior history that fits within the history windows), 1773 * before re-evaluation. 1774 * 1775 * FINDING BEST STARTING MODULATION MODE: 1776 * 1777 * After working with a modulation mode for a "while" (and doing rate scaling), 1778 * the driver searches for a new initial mode in an attempt to improve 1779 * throughput. The "while" is measured by numbers of attempted frames: 1780 * 1781 * For legacy mode, search for new mode after: 1782 * 480 successful frames, or 160 failed frames 1783 * For high-throughput modes (SISO or MIMO), search for new mode after: 1784 * 4500 successful frames, or 400 failed frames 1785 * 1786 * Mode switch possibilities are (3 for each mode): 1787 * 1788 * For legacy: 1789 * Change antenna, try SISO (if HT association), try MIMO (if HT association) 1790 * For SISO: 1791 * Change antenna, try MIMO, try shortened guard interval (SGI) 1792 * For MIMO: 1793 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) 1794 * 1795 * When trying a new mode, use the same bit rate as the old/current mode when 1796 * trying antenna switches and shortened guard interval. When switching to 1797 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate 1798 * for which the expected throughput (under perfect conditions) is about the 1799 * same or slightly better than the actual measured throughput delivered by 1800 * the old/current mode. 1801 * 1802 * Actual throughput can be estimated by multiplying the expected throughput 1803 * by the success ratio (successful / attempted tx frames). Frame size is 1804 * not considered in this calculation; it assumes that frame size will average 1805 * out to be fairly consistent over several samples.
