摘要
A communication method and system for supporting a high data transmission rate fuse 5G communication systems with IoT technology to transmit data at a high rate after 4G systems. The method for a terminal in a wireless communication system supporting carrier aggregation includes receiving a control message including indication information, the indication information indicating that physical uplink control channel (PUCCH) feedback for at least one secondary cell (SCell) is transmitted on a SCell; identifying whether the SCell is configured to the terminal and is activated; and if the SCell is configured to the terminal and is activated, obtaining Type 2 power headroom information for the SCell.

Additionally, the measurement instructing control message can include information additionally specifying nearby cells that do not need measurement result report when UE performs measurement in a frequency band of the unlicensed band. This information has a form of a Physical Cell Identifier (PCI) range. Cells have unique PCIs respectively. For example, a PCI range to be used for cells owned by operators can be limited according to operators. When the UE received the information, it can also receive a PCI range which needs the measurement result report or a PCI range which does not need the measurement result report, and may not perform measurement for nearby cells that do not need the measurement result report.
