The UE category defines a combined UL and DL capability. The DL parameters set by the UE categoryare given in Table 8, while the UL parameters set by the UE Category are given in Table 9. Both Table 8and Table 9 are specified in 3GPP TS 36.306. [10]Note that in order to preserve backward compatibility, a UE that indicates a Rel-10 UE Category mustalso indicate a Release 8 UE Category. A UE that indicates a Rel-11 UE Category must also indicateboth a Release 10 and a Release 8 UE Category.Table 8.
