The UE categories 21 to 24 have been introduced in R8. The following table provides
an overview.
From the table you can see that the maximum HSDPA data rate for an R8 UE equals
42.20 Mbps. So the maximum DL data rate for R7 with MIMO and R8 with dual carrier
is the same.
Properties common for all R8 categories:
●
only dual carrier operation, no single carrier operation
●
no MIMO operation
●
maximum number of HS-PDSCH channelization codes = 15
●
minimum inter TTI distance = 1

The UE categories 25 to 28 have been introduced in R9. The following table provides
an overview.
From the table you can see that the maximum number of bits per TTI for an R9 UE is
the same as in R8. So the maximum DL data rate for R8 (without MIMO) is the half of
maximum DL data rate for R9 with MIMO.
Properties common for all R9 categories:
●
only dual carrier operation, no single carrier operation
