Method and apparatus for performing and reporting measurements by user equipment configured with multiple carriers in mobile communication systems

PH is divided into Type 1 PH and Type 2 PH. Type 1 PH refers to a difference between the maximum transmission power of UE, defined according to serving cells, PCMAX,c and the transmission power required for PUSCH transmission. Type 2 PH refers to a difference between the maximum transmission power of UE PCMAX,c and the transmission power required for PUCCH transmission and PUSCH transmission, which are defined in the specification 36.213.
As mobile communication systems are evolved, the number of carriers which can be aggregated to one mobile device also increases. In particular, the number of aggregated carriers per mobile device is up to maximum 32 in a high level of development of carrier aggregation (CA) aiming at commercialization around 2017. As the number of aggregated carriers increases, the required capacity of Physical Uplink Control Channel (PUCCH; refer to specification 36.213) also increases. According to the current specification, PUCCH needs to be set in only a PCell and a PSCell, and this limits the increase in the capacity of PUCCH.
In order to resolve the problems, the first embodiment of the present disclosure provides a method of configuring PUCCH in a general SCell as well as in a PCell and a PSCell. In addition, the first embodiment of the present disclosure provides a method of defining: new PUCCH SCell type 2 PH, so that UE can report power headroom (PH) to the ENB, along with the information related to a PUCCH, and of determining whether PUCCH SCell type 2 PH is contained. The present disclosure also provides a new PHR format.
