20150023279 | PRE-CODING DEVICE, WIRELESS TRANSMISSION DEVICE, WIRELESS RECEIVING DEVICE, WIRELESS COMMUNICATION SYSTEM, AND INTEGRATED CIRCUIT - A terminal device knows which kind of pre-coding has been applied without increasing overhead in a wireless communication system in which plural kinds of pre-coding are selectively or simultaneously used. | 2015-01-22 |
20150023280 | METHOD FOR FEEDING BACK CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR - The present invention relates to a method for receiving a reference CSI configuration information and a following CSI configuration information which is configured to report a same RI (Rank Indicator) as the reference CSI configuration information, receiving a first CSI-RS (Channel State Information-Resource Signal) configuration information associated with the reference CSI configuration and a second CSI-RS configuration information associated with the following CSI configuration, number of CSI-RS antenna ports according to the second CSI-RS configuration information is same as number of CSI-RS antenna ports according to the first CSI-RS configuration information; and transmitting CSI determined based on at least one of the first CSI-RS configuration information and the second CSI-RS configuration information. | 2015-01-22 |
20150023281 | OPTIMIZED TRANSMISSION OF MACHINE TYPE COMMUNICATION DATA FROM A MOBILE DEVICE TO A WIRELESS NETWORK - A method of transmitting data from a UE to an eNB is provided. In response to a data transmission request from a MTC application, the UE chooses a preamble ID based on the data size and transmits a random access preamble message to the eNB. The eNB returns a random access response message to the UE. The random access response message identifies resource allocated in an uplink channel and includes one or more transmission power control parameters associated with the second uplink channel. After determining that the data size is less than or equal to the allocated resources in the second uplink channel, the UE transmits a scheduled transmission message to the eNB using the allocated resource in the second uplink channel at a transmission power level determined by the one or more transmission power control parameters. | 2015-01-22 |
20150023282 | TERMINAL DEVICE, BASE STATION DEVICE, AND INTEGRATED CIRCUIT - There are provided a terminal device, a base station device, and an integrated circuit that enable a base station device and a terminal device to determine parameters related to uplink signals or uplink reference signals and to perform efficient communication. A terminal device that transmits a demodulation reference signal associated with a physical uplink shared channel to a base station device includes determining a base sequence number on the basis of a value of a parameter configured by a higher layer, determining the base sequence number on the basis of a physical layer cell identity, and generating a sequence of the demodulation reference signal on the basis of the base sequence number, wherein the base sequence number is determined on the basis of the physical layer cell identity in a case where a transmission on the physical uplink shared channel corresponding to a downlink control information format to which CRC parity bits scrambled by a Temporary C-RNTI are attached is performed in a random access procedure. | 2015-01-22 |
20150023283 | METHODS AND APPARATUS FOR CELL SELECTION - The present disclosure relates to a cell selection scheme. In one embodiment, there provides a method for performing a cell selection for a UE at a primary serving cell of the UE in a CoMP cluster including the primary serving cell and one or more candidate cells, the method comprising the steps of: receiving PRACH measurements for the UE from the candidate cells; and selecting from the candidate cells one or more cells for the UE as its secondary serving cells based on the received PRACH measurements. | 2015-01-22 |
