3.9.12.2.6 Configuring Airframe Uplink Data Zone Parameter
To configure the Airframe Uplink Data Zone parameter, run the following
command:
npu(config-bs-66053-airframe)# uldatazone permbase <(0 to 69 StepSize 1)>
3.9.12.2.7 Configuring Airframe MIMO Parameters
The DL MIMO feature provides a TX diversity gain or, when physical conditions
allow, data rate gain (double rate).
The gain is allowed thanks to two or four transmitting antennas at the BS side,
two receiving antennas at the MS side, and encoding/decoding capabilities of both
MS and BS.
TX diversity gain is achieved when MS works at matrix A/STC, space time coding,
AKA STTD (vertical encoding) mode.
IMPORTANT
When creating a new BS, the Airframe Structure Uplink Data Zone mandatory permbase parameter
must be configured.
