Abstract

A user equipment in wireless communication system is provided. The user equipment includes an antenna unit including a plurality of antennas, a control unit for grouping the plurality of antennas into a predetermined number of antenna groups and controlling separately transmission power of each of the predetermined number of antenna groups, and a transmitting unit, connected to the control unit, for transmitting at least one of data and control information to a base station via at least one of the predetermined number of antenna groups.

Claims12

Dependent claims

A user equipment for supporting multiple component carriers through carrier aggregation, comprising:

a processor configured to determine a maximum transmission power PMAX,PUCCH of physical uplink control channel (PUCCH) and a maximum transmission power PMAX,PUSCH of physical uplink shared channel (PUSCH) for a component carrier x among the multiple component carriers;
and
a radio frequency (RF) unit, coupled to the processor, configured to transmit the PUCCH and the PUSCH on the component carrier x,
wherein the RF unit is further configured to receive control information associated with respective maximum allowed powers for the multiple component carriers,
wherein the maximum transmission power PMAX,PUCCH is set to be PPMAX,x, where PMAX,x is a maximum allowed power for the component carrier x, and
wherein the maximum transmission power PMAX,PUSCH is set to be ‘PMAX,x-PPUCCH’, where PPUCCH is a transmission power of the PUCCH.
