The

field

ue-Category

defines a combined uplink and downlink capability. The

parameters set by the UE Category are defined in subclause 4.2. Tables 4.1-1 and 4.1-2

define the downlink and, respectively, uplink physical layer parameter values for each

UE Category. A UE indicating category 6 or 7 shall also indicate category 4. A UE

indicating category 8 shall also indicate category 5. A UE indicating category 9 shall also

indicate category 6 and 4. A UE indicating category 10 shall also indicate category 7 and

4. A UE indicating category 11 shall also indicate category 9, 6 and 4. A UE indicating

category 12 shall also indicate category 10, 7 and 4. Table 4.1-4 defines the minimum

capability for the maximum number of bits of a MCH transport block received within a

TTI for an MBMS capable UE.

NOTE 1:

In carrier aggregation operation, the DL-SCH processing capability can be shared by

the UE with that of MCH received from a serving cell. If the total eNB scheduling for

DL-SCH and an MCH in one serving cell at a given TTI is larger than the defined

processing capability, the prioritization between DL-SCH and MCH is left up to UE

implementation.

ue-CategoryDL and ue-CategoryUL

The fields

ue- CategoryDL

and

ue- CategoryUL

define downlink/uplink capability

respectively. The parameters set by the UE DL/UL Categories are defined in subclause

4.2. Tables 4.1A-1 and 4.1A-2 define the downlink and, respectively, uplink physical

layer parameter values for each UE DL/UL Category

Table 4.1A-4 defines the minimum

capability for the maximum number of bits of a MCH transport block received within a

TTI for an MBMS capable UE. Table 4.1A-6 defines the only combinations for UE UL and

DL Categories that are allowed to be signalled with

ue-CategoryDL

and

ue-CategoryUL

.

Table 4.1A-6 also defines which UE Categories a UE shall indicate in addition to the

combinations for UE UL and DL Categories.
