Data rate gain is achieved when MS works at matrix B/SM, spatial multiplexing
MIMO mode.
It is assumed that either all MSs support MIMO (not necessary both modes) or all
MSs don't support MIMO (SIMO support only).
The DL MIMO feature influences several system elements such as frame
structure, rate adaptation and feedback zone.
To configure the Airframe MIMO parameters, run the following command:
npu(config-bs-66053-airframe)# mimo [first-zone-min-size <(-1 to -1 StepSize 1)
| (2 to 34 StepSize 2)> ] [first-zone-max-size <(-1 to -1 StepSize 1) | (2 to 34
StepSize 2)> ] [max-map-size <(-1 to -1 StepSize 1) | (10 to 300 StepSize 10)> ]
[bcast-msgzone-loc {nonSTCzoneOnly | stcZone} ]
NOTE
An attempt to configure the bcast-msgzone-loc parameter will be ignored. The value of this
parameter is set to.nonSTCZoneOnly.

Determines the initial size
(in OFDMA symbols) of the
first zone. When reuse 3 is
used within first zone, this
parameter should be equal
across all BSs within
deployment.
See recommended values
in Table
3-33 below. Other
values should be avoided.
