If no lower rate available, switch to 1622 * legacy mode (no HT40 channel, no MIMO, no short guard interval). 1623 * c) If using MIMO, set command's mimo_delimiter to number of entries 1624 * using MIMO (3 or 6). 1625 * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, 1626 * no MIMO, no short guard interval), at the next lower bit rate 1627 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow 1628 * legacy procedure for remaining table entries. 1629 * 1630 * 2) If using legacy initial rate: 1631 * a) Use the initial rate for only one entry. 1632 * b) For each following entry, reduce the rate to next lower available 1633 * rate, until reaching the lowest available rate. 1634 * c) When reducing rate, also switch antenna selection. 1635 * d) Once lowest available rate is reached, repeat this rate until 1636 * rate table is filled (16 entries), switching antenna each entry. 1637 * 1638 * 1639 * ACCUMULATING HISTORY 1640 * 1641 * The rate scaling algorithm for agn devices, as implemented in Linux driver, 1642 * uses two sets of frame Tx success history: One for the current/active 1643 * modulation mode, and one for a speculative/search mode that is being 1644 * attempted. If the speculative mode turns out to be more effective (i.e. 1645 * actual transfer rate is better), then the driver continues to use the 1646 * speculative mode as the new current active mode. 1647 * 1648 * Each history set contains, separately for each possible rate, data for a 1649 * sliding window of the 62 most recent tx attempts at that rate. The data 1650 * includes a shifting bitmap of success(1)/failure(0), and sums of successful 1651 * and attempted frames, from which the driver can additionally calculate a 1652 * success ratio (success / attempted) and number of failures 1653 * (attempted - success), and control the size of the window (attempted). 1654 * The driver uses the bit map to remove successes from the success sum, as 1655 * the oldest tx attempts fall out of the window. 1656 * 1657 * When the agn device makes multiple tx attempts for a given frame, each 1658 * attempt might be at a different rate, and have different modulation 1659 * characteristics (e.g. antenna, fat channel, short guard interval), as set 1660 * up in the rate scaling table in the Link Quality command. The driver must 1661 * determine which rate table entry was used for each tx attempt, to determine 1662 * which rate-specific history to update, and record only those attempts that 1663 * match the modulation characteristics of the history set. 1664 * 1665 * When using block-ack (aggregation), all frames are transmitted at the same 1666 * rate, since there is no per-attempt acknowledgment from the destination 1667 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in 1668 * rate_n_flags field. After receiving a block-ack, the driver can update 1669 * history for the entire block all at once. 1670 * 1671 * 1672 * FINDING BEST STARTING RATE: 1673 * 1674 * When working with a selected initial modulation mode (see below), the 1675 * driver attempts to find a best initial rate. The initial rate is the 1676 * first entry in the Link Quality command's rate table. 1677 * 1678 * 1) Calculate actual throughput (success ratio * expected throughput, see 1679 * table below) for current initial rate. Do this only if enough frames 1680 * have been attempted to make the value meaningful: at least 6 failed 1681 * tx attempts, or at least 8 successes. If not enough, don't try rate 1682 * scaling yet. 1683 * 1684 * 2) Find available rates adjacent to current initial rate. Available means: 1685 * a) supported by hardware && 1686 * b) supported by association && 1687 * c) within any constraints selected by user 1688 * 1689 * 3) Gather measured throughputs for adjacent rates. These might not have 1690 * enough history to calculate a throughput. That's okay, we might try 1691 * using one of them anyway! 1692 * 1693 * 4) Try decreasing rate if, for current rate: 1694 * a) success ratio is < 15% || 1695 * b) lower adjacent rate has better measured throughput || 1696 * c) higher adjacent rate has worse throughput, and lower is unmeasured 1697 * 1698 * As a sanity check, if decrease was determined above, leave rate 1699 * unchanged if: 1700 * a) lower rate unavailable 1701 * b) success ratio at current rate > 85% (very good) 1702 * c) current measured throughput is better than expected throughput 1703 * of lower rate (under perfect 100% tx conditions, see table below) 1704 * 1705 * 5) Try increasing rate if, for current rate: 1706 * a) success ratio is < 15% || 1707 * b) both adjacent rates' throughputs are unmeasured (try it!) || 1708 * b) higher adjacent rate has better measured throughput || 1709 * c) lower adjacent rate has worse throughput, and higher is unmeasured 1710 * 1711 * As a sanity check, if increase was determined above, leave rate 1712 * unchanged if: 1713 * a) success ratio at current rate < 70%. This is not particularly 1714 * good performance; higher rate is sure to have poorer success. 1715 * 1716 * 6) Re-evaluate the rate after each tx frame. If working with block- 1717 * acknowledge, history and statistics may be calculated for the entire 1718 * block (including prior history that fits within the history windows), 1719 * before re-evaluation. 1720 * 1721 * FINDING BEST STARTING MODULATION MODE: 1722 * 1723 * After working with a modulation mode for a "while" (and doing rate scaling), 1724 * the driver searches for a new initial mode in an attempt to improve 1725 * throughput. The "while" is measured by numbers of attempted frames: 1726 * 1727 * For legacy mode, search for new mode after: 1728 * 480 successful frames, or 160 failed frames 1729 * For high-throughput modes (SISO or MIMO), search for new mode after: 1730 * 4500 successful frames, or 400 failed frames 1731 * 1732 * Mode switch possibilities are (3 for each mode): 1733 * 1734 * For legacy: 1735 * Change antenna, try SISO (if HT association), try MIMO (if HT association) 1736 * For SISO: 1737 * Change antenna, try MIMO, try shortened guard interval (SGI) 1738 * For MIMO: 1739 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) 1740 * 1741 * When trying a new mode, use the same bit rate as the old/current mode when 1742 * trying antenna switches and shortened guard interval. When switching to 1743 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate 1744 * for which the expected throughput (under perfect conditions) is about the 1745 * same or slightly better than the actual measured throughput delivered by 1746 * the old/current mode. 1747 * 1748 * Actual throughput can be estimated by multiplying the expected throughput 1749 * by the success ratio (successful / attempted tx frames). Frame size is 1750 * not considered in this calculation; it assumes that frame size will average 1751 * out to be fairly consistent over several samples.
