The present disclosure relates to an operating method of a terminal for transceiving data to/from a base station in a system that supports a plurality of component carriers. The method includes receiving, from the base station, downlink control information (DCI) masked using a terminal identifier (cell-radio network temporary identifier (C-RNTI)) or a semi-persistent scheduling terminal identifier (SPS C-RNTI) through a physical downlink control channel (PDCCH); determining a component carrier for transceiving data to/from the base station; and transceiving data to/from the base station through the determined component carrier. The determining includes determining the component carrier which has received the PDCCH as a component carrier for receiving downlink data, and determining an uplink component carrier linked with the component carrier which has received the PDCCH as a component carrier for transmitting uplink data.
Abstract:
The present invention relates to a wireless access system supporting multi-carrier aggregation (CA) and discloses various methods and devices for aperiodic feedback of channel state information (CSI). The method for aperiodic feedback of the channel state information (CSI) in the wireless access system supporting the multi-carrier aggregation (CA), according to an embodiment of the present invention, comprises the steps of: receiving a first message including an aperiodic CSI request field and uplink grant from a base station; receiving a second message including bitmap information indicating a downlink component carrier (DL CC) subjected to CSI measurement from the base station; measuring the CSI in consideration of at least one of the aperiodic CSI request, uplink grant, and bitmap information; and transmitting the measured CSI to the base station through a physical uplink shared channel (PUSCH) to thereby receive aperiodic feedback of the same.
Abstract:
A wireless communication system is disclosed. Disclosed herein are methods for transmitting a physical uplink control channel (PUCCH) signal in a wireless communication system, which includes setting transmit power for the PUCCH signal, and an apparatus thereof. If the PUCCH signal is transmitted on a subframe configured for a scheduling request (SR), the PUCCH signal includes one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) bits and an SR bit. When determining the transmit power for the PUCCH, the SR bit is selectively considered depending on whether or not a transport block for an uplink shared channel (UL-SCH) is present in the subframe.
Abstract:
A method of performing paging by a first D2D terminal in a wireless communication system supporting D2D communication includes: obtaining information on a paging slot, the paging slot being designated to be dedicated to the first D2D terminal for the D2D communication and including a plurality of paging sections; monitoring whether a signal for the first D2D terminal is transmitted in a first paging section in the obtained paging slot through a region assigned to the first D2D terminal; monitoring whether a paging request message is transmitted in a paging region only for the first D2D terminal in a second paging section if the signal is detected; and transmitting a paging response message through a third paging section to the second D2D terminal that transmits the paging request signal, as a response to the paging request message, if the paging request message is detected.
Abstract:
The present invention relates to a method for receiving control information on a terminal in a wireless communication system, including the steps of: transmitting uplink data to a base station through a physical uplink shared channel; and receiving a downlink control information (DCI) format related to an uplink approval, wherein, when the DCI format meets predetermined conditions, the terminal considers the DCI format as an acknowledgement for the uplink data.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for reporting CSI in a wireless communication system, the method comprising: a step for configuring a plurality of serving cells; and a step for reporting the CSI of only one serving cell in a corresponding subframe, wherein the step for reporting the CSI of only one serving cell comprises: excluding reporting the CSI of a lower priority when CSI reports of the plurality of serving cells in the corresponding subframe collide; and excluding reporting the CSI of serving cells other than the serving cell having the smallest index when the CSI reports of different serving cells having the same priority in the corresponding subframe collide.
