The sum of each TRX configured maximum output power is bigger than PA maximum output
power.
In the area with little traffic, BCCH carrier power configuration can be appropriately added by
taking use of dynamic power, and the remaining power is dynamically real-time shared among
all TCH carriers to enlarge coverage and reduce site quantity.

13. Powerful HSPA+ Capability, Smooth Evolution
Uni-RAN solution based on the design of
smooth HSPA evolution.
From R5 to R6, R7, R8, Uni-RAN aims at higher
data throughput and lower cost per bit.
With the same hardware, full HSPA evolution
performance can be supported
