Abstract: A method and user equipment (UE) are provided for concurrently accessing a plurality of cells. The UE sets a connection with any one cell corresponding to a primary cell among frequency division duplex (FDD)-based cells and time division duplex (TDD)-based cells, and receives, from the any one cell, first cell indexes for the FDD-based cells and second cell indexes for the TDD-based cells. The UE further sets a connection with a secondary cell indicated by any one index among the first cell indexes and the second cell indexes. At least one value among the first cell indexes overlaps with at least one of the second cell indexes.

Abstract: A method and apparatus for transmitting a power headroom report (PHR) in a wireless communication system is provided. A user equipment (UE) transmits a first PHR for a first carrier group, which is configured by a first eNodeB (eNB), to a second eNB; and transmits ing a second PHR for a second carrier group, which is configured by the second eNB, to the first eNB. The first PHR and the second PHR include a PHR for a physical uplink control channel (PUCCH) regardless of whether simultaneous transmission of the PUCCH and a physical uplink shared channel (PUSCH) is configured or not.
