DBMs are NOT visible in MOM, may
however
be visible in MP SW for resource
handling
Proposed
mapping:
• One RaxDeviceGroup per RXM on
DUW.
• One TxDeviceGroup for all
TXMs
• Future possibility to distribute TXMs over
two TxDeviceGroups

Each DUW can control up to 6 cc
Each RU 4 carriers (60w)

Resource_ID
›A resource_ID (TXM) on a DUW can be used for the
following purposes
–Up to 6 cell carriers HSDPA with a maximum of 30 HS codes and up to
128 users (max 96 users per cell)
–R99 DCH with a capacity of 128CE
–6 cell carriers EUL with up to 96 users (max 48 users per cell carrier)
›We can treat one TXM on a DUW as HSPDA processing
resource.
