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(shuō)明書(shū)

The LTE and LTE-A systems, as typical examples of the broadband wireless communication systems, employ Orthogonal Frequency Division Multiplexing (OFDM) in the downlink and Single Carrier-Frequency Division Multiple Access (SC-FDMA) in the uplink. The Multiple Access performs allocation and management of time-frequency resources to carry data and control information according to users, so as not to overlap each other, i.e., so as to achieve orthogonality between them, thereby distinguishing data or control information between respective users.
