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 transmitting 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.
Claims16
A method performed by a first base station in a wireless communication system with dual connectivity, the method comprising:
- receiving a type 1 power headroom for all activated carriers of the first base station and a second base station from a user equipment (UE);
- and
- receiving a type 2 power headroom for a carrier which can transmit a physical uplink control channel (PUCCH) for the second base station from the UE,
- wherein the UE is connected to both the first base station and the second base station in the dual connectivity.
A first base station (BS) in a wireless communication system with dual connectivity, the first BS comprising:
- a memory;
- a radio frequency (RF) unit;
- and
- a processor, operably coupled to the memory and the RF unit, and that controls the RF unit to:
- receive a type 1 power headroom for all activated carriers of the first base station and a second base station from a user equipment (UE), and
- receive a type 2 power headroom for a carrier which can transmit a physical uplink control channel (PUCCH) for the second base station from the UE,
- wherein the UE is connected to both the first base station and the second base station in the dual connectivity.
