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.

說明書

Measuring an unlicensed band operating in FDD mode means that: in a state where the forward sub-frame structure of cells of a corresponding band follows a particular pattern, UE detects that the pattern of sub-frames transmitting PSS/SSS signals also follows the FDD operation mode, specifies a time interval when signals required for measurement will be received, and performs measurement in the corresponding time interval. In addition, measuring an unlicensed band operating in TDD mode means that: in a state where the forward sub-frame structure of cells of a corresponding band follows another particular pattern, UE detects that the pattern of sub-frames transmitting PSS/SSS signals also follows the TDD operation mode, specifies a time interval when signals required for measurement will be received, and performs measurement in the corresponding time interval.
