| Abstract(in English) | A higher frequency band is considered to be used for future mobile communications. However, reliable transmission may not be possible in an uplink channel because of limited transmit power of terminals. We can improve uplink transmission performance using a virtual antenna array which is formed by multiple terminals cooperating with each other. However, in this system, the terminals need information about transmit weight, frequency offset, and transmit power ratio from a base station. The feedback of the information from a base station limits downlink transmission. In this paper, we propose a codebook for transmit weight, and quantization of frequency offset and transmit power ratio. We examine the impact of them on the bit error rate performance. |
