Chapter 4 - Operation and Administration
The range is from 1 to 17 for a 5 MHz BS bandwidth and from 1 to 35 for a 7MHz
or 10 MHz BS bandwidth.
The default is 4 sub-channels.
4.8.2.2.4.2 Uplink Multi Rate Support
Defines whether the multi rate algorithm will be used in the uplink. Under normal
operating conditions the Uplink Multi Rate Support should always be enabled.The
option to disable it is provided primarily for testing purposes.
The default is Enable.
4.8.2.2.4.3 Uplink Basic Rate
When Uplink Multi Rate Support is enabled, the Uplink Basic Rate defines the
lowest rate that can be used by the multi rate algorithm in the uplink. MSs that
cannot communicate with the BS at this rate will not be served. This can be used
to deny service to MSs with very poor link conditions, thus improving the overall
capacity.
When Uplink Multi Rate Support is disabled, this is the fixed rate at which the BS
will communicate with all MSs it can serve.
The available options are:
QPSK-CTC-1/2 REP4
QPSK-CTC-1/2 REP2
QPSK-CTC-1/2
QPSK-CTC-3/4
QAM16-CTC-1/2
QAM16-CTC-3/4
QAM64-CTC-2/3
QAM64-CTC-3/4
QAM64-CTC-5/6
The default rate is QPSK-CTC-1/2.
