Abstract
A transmitting device includes a plurality of transmission antennas, and includes: a signal processor which generates a first baseband signal by modulating data of a first stream, and a second baseband signal by modulating data of a second stream; and a transmitter which generates, from the first baseband signal, first transmission signals having different directivities, generates, from the second baseband signal, second transmission signals having different directivities, and transmits the first transmission signals and the second transmission signals at a same time.
Claims4
A user terminal comprising:
- a receiver configured to receive a first signal and a second signal from a first communication device and a second communication device, respectively, the first signal and the second signal each carrying same information, reception of the first signal being overlapped in a time domain or a frequency domain with reception of the second signal;
- and
- a processor configured to obtain the same information based on the reception,
- wherein the first communication device is included in a first base station, and the second communication device is included in a second base station different from the first base station,
- wherein the reception of the second signal is partially overlapped in the time domain with the reception of the first signal without the reception of the second signal being fully overlapped in the time domain with the reception of the first signal,
- wherein the processor is further to configured to select one communication device from among the first communication device and the second communication device after receiving the first signal and the second signal, and
- wherein the receiver is further configured to receive a signal from the selected one communication device.
