When a number of PUCHC SCells are configured in UE, a number of SCell Type 2 PH can be contained. In this case, UE contains SCell Type 2 PH in the sequence of identifiers of PUCCH SCell.
Type 1 PH (840) of PCell and PCMAX,c (845)
Type 1 PH of SCell and PCMAX,c in the sequence of SCell identifiers.
FIG. 9 is a diagram showing the configuration of UE according to a first embodiment of the present disclosure;
Referring to FIG. 9, the UE is capable of including at least one of the following: a transceiver 905, a controller 910, a multiplexer and demultiplexer 920, a control message processor 930, and upper layer devices 920 and 925.
The multiplexer and demultiplexer 920 and the controller 910 form an MAC device. Although the embodiment of FIG. 9 is, for the sake of convenience, described without separating components from each other, it can be modified in such a way that an MAC device for MCG and an MAC device for SCG are configured separately when DC is configured.
