configuring, by the network, p CCs, from among the k CCs, with a configuration exceeding both first and second capability, p being equal to the smaller of k and N-k.
10. A method, comprising:
sending, by a user equipment (UE), to a network, a declaration of capabilities,
the declaration of capabilities comprising:
a declaration of a first capability for a first component carrier (CC), and
a declaration of a second capability for a second CC; and
configuring, by the UE, in response to a configuration command received from the network, one or more CCs including the first CC and not including the second CC,
the configuring comprising configuring the first CC with a configuration exceeding the first capability.
