The antenna port includes three RE groups in a PRB pair. One RE group includes two RE pairs. One RE pair includes two consecutive | 07-31-2014 |
20140355560 | DEVICE AND METHOD FOR TRANSMITTING RANDOM ACCESS PREAMBLE - Base Station (BS) and User Equipment (UE) apparatuses for configuring a Random Access CHannel (RACH), and methods thereof, are provided. The method for a BS to configure a RACH includes generating configuration information on RACH resources, transmitting the configuration information on the RACH resources to a UE, receiving a random access preamble multiplexed on a plurality of continuous RACH resources from the UE, extracting the random access preamble multiplexed on the plurality of continuous RACH resources, and detecting the extracted random access preamble. The method for a UE to configure a RACH includes receiving configuration information on RACH resources from a BS, selecting occupied RACH resources among a plurality of continuous RACH resources, generating a random access preamble, multiplexing the generated random access preamble on the selected RACH resources, and transmitting the random access preamble on the selected RACH resources to the BS. | 12-04-2014 |

20150085815 | METHOD FOR FEEDING BACK ACK/NACK FOR DOWNLINK DATA TRANSMISSION IN RADIO COMMUNICATION SYSTEM - Embodiments of the present invention provide a method for feeding back ACK/NACK for downlink data transmission in a radio communication system. The method is applied on a mobile terminal and includes the following steps: receiving downlink data, calculating, with respect to each Component Carrier (CC), a number of ACKs of ACK/NACK information of downlink data sub-frames of the CC, and feeding back numbers of ACKs of the ACK/NACK information of the downlink data sub-frames of CCs. | 03-26-2015 |
