The method includes receiving via at least one of the plurality of sectors a data packet from the mobile terminal, the data packet being correspondingly received for each of the at least one of the plurality of sectors; combining the correspondingly received data packets, to obtain a signal having a highest signal-to-noise ratio; decoding the value obtained by the combining; determining a transmission status of the data packet according to the decoding; and transmitting to the mobile terminal a common ACK/NACK signal including one of a common ACK signal and a common NACK signal according to the determining, the common ACK/NACK signal being transmitted via each of the at least one sector. | 10-09-2014 |
20140301357 | METHOD AND APPARATUS FOR ALLOCATING A PLURALITY OF DATA SYMBOLS IN A WIRELESS COMMUNICATION SYSTEM - According to one embodiment, a method for transmitting an uplink signal includes transmitting the uplink signal including a block of data symbols. The block of data symbols are mapped to at least two sets of subcarrier blocks. Each data symbol of the block of data symbols is mapped to one of subcarriers of the at least two sets of subcarrier blocks. The at least two sets of subcarrier blocks are not contiguous in frequency. The block of data symbols are mapped in sequence starting with a first data symbol to the at least two sets of subcarrier blocks and in increasing order of subcarrier index. | 10-09-2014 |
