A method for transmitting an uplink comprises the steps of: a terminal receiving periodic channel state information (CSI) configuration information; the terminal determining an uplink subframe according to the periodic CSI configuration information; and the terminal transmitting a periodic CSI through the uplink subframe, wherein the periodic CSI configuration information may include information regarding a period, subframe offset, and a reference cell to which a wireless frame number is applied. | 07-09-2015 |
20150208358 | METHOD AND APPARATUS FOR SETTING UPLINK TRANSMISSION POWER IN WIRELESS COMMUNICATION SYSTEM - Provided are a method and a terminal device for setting uplink transmission power in a wireless communication system. A terminal acquires information on the time alignment group (TAG) for multiple supportable serving cells so as to constitute TAGs, checks whether an overlap section of subframe n and subframe n+1 for uplink transmission exists between TAGs, and sets uplink transmission power so as to scale the uplink transmission power (P | 07-23-2015 |
20150215095 | METHOD AND APPARATUS FOR TRANSMITTING SOUNDING REFERENCE SIGNAL - A method for transmitting a sounding reference signal (SRS) in a wireless communication system is provided. A user equipment receives downlink control information from a first serving cell and transmits a SRS through a second serving cell. If the first serving cell is a FDD cell and the second serving cell is a TDD cell, the downlink control information includes an aperiodic SRS request. If the first serving cell is the TDD cell and the second serving cell is the FDD cell, the downlink control information does not include the aperiodic SRS request. | 07-30-2015 |
20150215877 | APPARATUS AND METHOD FOR REPORTING POWER HEADROOM IN WIRELESS COMMUNICATION SYSTEM - Provided are an apparatus and a method for reporting a power headroom in a wireless communication system. A terminal may check the configuration of a plurality of subframes for multiple serving cells, determine at least one power headroom (PH) in correspondence to at least one subframe corresponding to the subframe for which an uplink configuration is established, from among the plurality of subframes, and perform a power headroom report (PHR) including said at least one PH. | 07-30-2015 |
20150245323 | METHOD AND USER EQUIPMENT FOR RECEIVING DOWNLINK SIGNAL AND METHOD AND BASE STATION FOR TRANSMITTING DOWNLINK SIGNAL - The present invention provides: a base station for repeatedly transmitting a physical downlink control channel (PDCCH) during a first subframe bundle comprising a plurality of subframes, and transmitting a PDSCH related to the PDCCH; and user equipment for receiving the PDCCH and the PDSCH. The PDSCH can be transmitted to the user equipment starting from subframe n+k, which is the k | 08-27-2015 |
20150245347 | METHOD AND APPARATUS FOR PERFORMING UPLINK TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM - A method for and apparatus for transmitting uplink transmission in a wireless communication system supporting multiple carriers is provided. A wireless device transmits the uplink transmission via an alternative Primary serving cell or Secondary serving cell in uplink between the UE and the eNB. Herein the uplink transmission is configured by enabling information with corresponding serving cell as the Primary serving cell or the Secondary serving cell for the uplink transmission. And then, a PUCCH and/or PUSCH can performed on the enabling serving cell and/or cells in consideration of power control more accurately and efficiently. | 08-27-2015 |
