If no lower rate available, switch to 1571 * legacy mode (no HT40 channel, no MIMO, no short guard interval). 1572 * c) If using MIMO, set command's mimo_delimiter to number of entries 1573 * using MIMO (3 or 6). 1574 * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, 1575 * no MIMO, no short guard interval), at the next lower bit rate 1576 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow 1577 * legacy procedure for remaining table entries. 1578 * 1579 * 2) If using legacy initial rate: 1580 * a) Use the initial rate for only one entry. 1581 * b) For each following entry, reduce the rate to next lower available 1582 * rate, until reaching the lowest available rate. 1583 * c) When reducing rate, also switch antenna selection. 1584 * d) Once lowest available rate is reached, repeat this rate until 1585 * rate table is filled (16 entries), switching antenna each entry. 1586 * 1587 * 1588 * ACCUMULATING HISTORY 1589 * 1590 * The rate scaling algorithm for agn devices, as implemented in Linux driver, 1591 * uses two sets of frame Tx success history: One for the current/active 1592 * modulation mode, and one for a speculative/search mode that is being 1593 * attempted. If the speculative mode turns out to be more effective (i.e. 1594 * actual transfer rate is better), then the driver continues to use the 1595 * speculative mode as the new current active mode. 1596 * 1597 * Each history set contains, separately for each possible rate, data for a 1598 * sliding window of the 62 most recent tx attempts at that rate. The data 1599 * includes a shifting bitmap of success(1)/failure(0), and sums of successful 1600 * and attempted frames, from which the driver can additionally calculate a 1601 * success ratio (success / attempted) and number of failures 1602 * (attempted - success), and control the size of the window (attempted). 1603 * The driver uses the bit map to remove successes from the success sum, as 1604 * the oldest tx attempts fall out of the window. 1605 * 1606 * When the agn device makes multiple tx attempts for a given frame, each 1607 * attempt might be at a different rate, and have different modulation 1608 * characteristics (e.g. antenna, fat channel, short guard interval), as set 1609 * up in the rate scaling table in the Link Quality command. The driver must 1610 * determine which rate table entry was used for each tx attempt, to determine 1611 * which rate-specific history to update, and record only those attempts that 1612 * match the modulation characteristics of the history set. 1613 * 1614 * When using block-ack (aggregation), all frames are transmitted at the same 1615 * rate, since there is no per-attempt acknowledgment from the destination 1616 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in 1617 * rate_n_flags field. After receiving a block-ack, the driver can update 1618 * history for the entire block all at once. 1619 * 1620 * 1621 * FINDING BEST STARTING RATE: 1622 * 1623 * When working with a selected initial modulation mode (see below), the 1624 * driver attempts to find a best initial rate. The initial rate is the 1625 * first entry in the Link Quality command's rate table. 1626 * 1627 * 1) Calculate actual throughput (success ratio * expected throughput, see 1628 * table below) for current initial rate. Do this only if enough frames 1629 * have been attempted to make the value meaningful: at least 6 failed 1630 * tx attempts, or at least 8 successes. If not enough, don't try rate 1631 * scaling yet. 1632 * 1633 * 2) Find available rates adjacent to current initial rate. Available means: 1634 * a) supported by hardware && 1635 * b) supported by association && 1636 * c) within any constraints selected by user 1637 * 1638 * 3) Gather measured throughputs for adjacent rates. These might not have 1639 * enough history to calculate a throughput. That's okay, we might try 1640 * using one of them anyway! 1641 * 1642 * 4) Try decreasing rate if, for current rate: 1643 * a) success ratio is < 15% || 1644 * b) lower adjacent rate has better measured throughput || 1645 * c) higher adjacent rate has worse throughput, and lower is unmeasured 1646 * 1647 * As a sanity check, if decrease was determined above, leave rate 1648 * unchanged if: 1649 * a) lower rate unavailable 1650 * b) success ratio at current rate > 85% (very good) 1651 * c) current measured throughput is better than expected throughput 1652 * of lower rate (under perfect 100% tx conditions, see table below) 1653 * 1654 * 5) Try increasing rate if, for current rate: 1655 * a) success ratio is < 15% || 1656 * b) both adjacent rates' throughputs are unmeasured (try it!) || 1657 * b) higher adjacent rate has better measured throughput || 1658 * c) lower adjacent rate has worse throughput, and higher is unmeasured 1659 * 1660 * As a sanity check, if increase was determined above, leave rate 1661 * unchanged if: 1662 * a) success ratio at current rate < 70%. This is not particularly 1663 * good performance; higher rate is sure to have poorer success. 1664 * 1665 * 6) Re-evaluate the rate after each tx frame. If working with block- 1666 * acknowledge, history and statistics may be calculated for the entire 1667 * block (including prior history that fits within the history windows), 1668 * before re-evaluation. 1669 * 1670 * FINDING BEST STARTING MODULATION MODE: 1671 * 1672 * After working with a modulation mode for a "while" (and doing rate scaling), 1673 * the driver searches for a new initial mode in an attempt to improve 1674 * throughput. The "while" is measured by numbers of attempted frames: 1675 * 1676 * For legacy mode, search for new mode after: 1677 * 480 successful frames, or 160 failed frames 1678 * For high-throughput modes (SISO or MIMO), search for new mode after: 1679 * 4500 successful frames, or 400 failed frames 1680 * 1681 * Mode switch possibilities are (3 for each mode): 1682 * 1683 * For legacy: 1684 * Change antenna, try SISO (if HT association), try MIMO (if HT association) 1685 * For SISO: 1686 * Change antenna, try MIMO, try shortened guard interval (SGI) 1687 * For MIMO: 1688 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) 1689 * 1690 * When trying a new mode, use the same bit rate as the old/current mode when 1691 * trying antenna switches and shortened guard interval. When switching to 1692 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate 1693 * for which the expected throughput (under perfect conditions) is about the 1694 * same or slightly better than the actual measured throughput delivered by 1695 * the old/current mode. 1696 * 1697 * Actual throughput can be estimated by multiplying the expected throughput 1698 * by the success ratio (successful / attempted tx frames). Frame size is 1699 * not considered in this calculation; it assumes that frame size will average 1700 * out to be fairly consistent over several samples.
