Chapter 4 - Operation and Administration
between Matrix A and Matrix B is performed automatically for each MS according
to link conditions (PER) and supported MS capabilities.
The default for 1DIV units is MIMO Matrix A.
4.8.2.2.3.2
UL Thermal Noise Level (dBm)
This parameter defines the target noise level to be used for calculating uplink
CINR values that are necessary for various functions such as the power control
mechanism. The BS broadcasts the targeted UL Thermal Noise Level level that is
used by the MSs in open loop power control mode. Increasing the advertised NI
causes the MS to transmit more power to support the same modulation. The NI
value is typically set 6 dB higher than prevailing thermal noise.
The range is from -130 to -100 dBm.
The default is -125 dBm.
CAUTION
A correct value of this parameter is critical for proper performance of the system. Do not change it
from the default value unless advised to modify it by Alvarion's experts.
4.8.2.2.3.3
DL HARQ Channels
The number of HARQ channels to be used for the WiMAX management connection
in the downlink.
The range is from 8 to 16.
The default is 16.
In 3.x GHz units, to support operation with BreezeMAX 1000 series CPEs, the DL
HARQ Channels parameters should be set to 10. Otherwise, the value should not
be changed from the default.
4.8.2.2.3.4
UL HARQ Channels
The number of HARQ channels to be used for the WiMAX management connection
in the uplink.
The range is from 8 to 10.
In 3.x GHz units, to support operation with BreezeMAX 1000 CPEs, the UL HARQ
Channels parameter should be set to 8. Otherwise, it should not be changed from
the default.
The default is 10.
4.8.2.2.3.5
HARQ On Management
Indicates whether the WiMAX management connection should have HARQ.
