As shown, carriers can be combined in the same or different frequency bands. Additionally, or alternatively, contiguous or non-contiguous carriers can be combined.

- Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5.
- a UE When a UE is configured for carrier aggregation, it may be possible for a UE to use a different antenna type relative to a per band capability. For example, in carrier aggregation, some ATG UEs may only be able to use a single type of antenna. Different RRM configurations may be used for a PCell for an ATG UE when the ATG UE is using an omnidirectional antenna relative to when the ATG UE is using a phased array antenna. For example, when using an omnidirectional antenna, the ATG UE may have a receive beam sweeping scaling factor of 1.
- the ATG UE may have a receive beam sweeping scaling factor of 3 (e.g., when network assistance on ATG cells reference locations is enabled) or 4 (e.g., when network assistance is not enabled) .

Additionally, or alternatively, the UE 120 may indicate an intra-band maximum output power for a set of bands. Alternatively, the UE 120 may report the capacity for the maximum output power as a set of separate values for different antenna types per band. As an example, the UE 120 may report an inter-band maximum output power for a set of bands.

In other words, the UE 120 may report a first k1 value for a first band (e.g., with a first antenna type) and a second k1 value for a second band (e.g., with a second antenna type) . Additionally, or alternatively, the UE 120 may report a maximum quantity of HARQ processes (maxHARQ-ProcessNumber) on a per band combination basis.
