Abstract:
Provided is a method for transmitting control information through an uplink by a terminal of a wireless communication system. The terminal generates a first bit stream for first control information and a second bit stream for second control information, determines the transmission power of the first bit stream and the second bit stream on the basis of the weight of the first control information with respect to the second control information, generates the multiplexed bit stream by multiplexing the first bit stream and the second bit stream, and transmits the multiplexed bit stream to a base station on the basis of the transmission power.
Abstract:
Provided are a method and an apparatus for determining transmission power of a preamble in a wireless communication system. A terminal estimates secondary cell (SCell) path loss with respect to a downlink (DL) component carrier (CC), which is in a linkage relationship with an uplink (UL) component carrier inside the SCell; decides the transmission power of a physical random access channel (PRACH) preamble based on the SCell path loss that is estimated; and transmits the PRACH preamble to a base station through the UL CC inside the SCell, based on the transmission power that is decided, wherein the SCell and a primary cell (PCell) comprises a carrier aggregation (CA) system, the PCell is a cell from which the terminal performs radio resource control (RRC) connection with the base station, and wherein the Scell is at least one cell from residual cells in the carrier aggregation excluding the PCell.
Abstract:
Provided are a method and an apparatus for transmitting periodic channel state information (CSI) in a wireless communication system. User equipment activates an uplink (UP) semi-persistent scheduling (SPS) session allocated to a secondary cell (SCell), periodically transmits the periodic CSI through a physical uplink shared channel (PUSCH) to a base station on the basis of the UL SPS session allocated to the SCell, and releases the UL SPS session allocated to the SCell.
