Multiplexing Gain This specifies the ratio between the number of logical slots and the
number of physical slots used.
A physical slot is an OFDM symbol. In non MU-MIMO mode, each
logical slot is sent during one physical slot. In MU-MIMO mode a
number of logical slots are sent during a physical slot, equal to the
number of VCs in the group. A logical slot carries new information; if
data is repeated in a group, because some VCs have more data to
send then others, then the repeated transmissions are not counted
as a logical slots.
Without MU-MIMO operation, the multiplexing gain would always be
equal to 1.
With MU-MIMO operation, this number accounts for parallel
transmissions to multiple users in the MU-MIMO group.
The difference between the Average MU-MIMO Group Size and the
Multiplexing Gain is that the Average MU-MIMO Group Size only
considers the MU-MIMO groups, and it averages the number of VCs
in the Group. The Multiplexing Gain also considers non MU-MIMO
transmissions, which are counted as groups of size 1.
Sector Utilization
SU-MIMO This specifies the portion of the Total Utilization used for SU-MIMO
transmissions.
MU-MIMO This specifies the portion of the Total Utilization used for MU-MIMO
transmissions.
ACK This specifies the portion of the Total Utilization used for
acknowledgments transmission.
MU-MIMO ACK This specifies the portion of the Total Utilization used for
acknowledgements transmissions that are MU-MIMO scheduled.
Currently only the UL direction supports MU-MIMO scheduling of
ACK's.
Broadcast & Multicast This specifies the portion of the Total Utilization used for broadcast
and multicast transmissions.
Slots Counts - Uplink and Downlink Slot Counts
Per Frame Average This indicates the average data per frame in the downlink traffic.
Low Priority The number of downlink data slots used for low priority downlink
traffic.
Medium Priority The number of downlink data slots used for medium priority
downlink traffic.
High Priority The number of downlink data slots used for high priority downlink
traffic.
