20130243110 | Multi-Layer Beamforming with Partial Channel State Information - A method of determining precoding information for beamforming between a sender and a receiver the method includes determining a first precoding vector of a first signal layer based on partial channel state information of a channel between the sender and the receiver. The method also includes determining a first guess vector based on long-term characteristics of the channel between the sender and the receiver. A grouping of antennas of the sender is defined and a phase shift value for each group of antennas is specified. The method further includes determining a second precoding vector in the sender of a second signal layer by multiplying each element in the first guess vector with the phase shift value specified for the group of antennas associated with said element in the first guess vector. | 09-19-2013 |
20130336220 | Single Carrier Cell Aggregation - It is provided an apparatus, including first receiving means adapted to receive a first signal from a first cell on a first carrier of a cellular network; second receiving means adapted to receive a second signal from a second cell on the first carrier, wherein the first cell is different from the second cell; combining means adapted to combine the first signal and the second signal to a single incoming data unit of a radio link control layer of the cellular network. | 12-19-2013 |
20150163773 | COMMUNICATION METHOD, BASE STATION AND USER EQUIPMENT - The present disclosure provides a communication method, base station and user equipment for configuring a parameter table in a wireless communication system including a base station and a user equipment, the communication method comprising: defining at both the base station and the user equipment a parameter table which includes whole entries of a legacy parameter table and extended entries; and transmitting from the base station to the user equipment a bitmap indication which indicates a sub-table selected from the parameter table, wherein the number of the entries in the sub-table is the same as in the legacy parameter table. | 06-11-2015 |
20150304998 | BASE STATION, TERMINAL, TRANSMISSION METHOD, AND RECEPTION METHOD - Disclosed is a base station capable of appropriately configuring a resource on which EPDCCH is located when soft combining is applied. The base station includes configuration section ( | 10-22-2015 |
20150358998 | DYNAMIC TDD UPLINK/DOWNLINK CONFIGURATION USING DCI - The invention relates to a method for dynamically indicating a TDD reconfiguration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication. | 12-10-2015 |
20160050153 | METHOD OF MAPPING CSI-RS PORTS TO RESOURCE BLOCKS, BASE STATION AND USER EQUIPMENT - The present disclosure provides a communication method that a base station configures different CSI-RS ports with different periodicity based on UE requirement (e.g. mobility) to reduce CSI-RS overhead. And another method is to transmit partial CSI-RS ports in a cyclic shifted manner to further reduce the overhead. In addition, cyclic shifted transmission of split CSI-RS port groups are proposed to reduce the potential big difference of interference onto different CSI-RS port groups. | 02-18-2016 |
20160087709 | TRANSMISSION APPARATUS AND CONTROL SIGNAL MAPPING METHOD - Disclosed is a transmission apparatus which enables high transmission-rate communication by mapping DMRSs in a way adapted to the reception environment of each terminal.
