Abstract
This wireless communication system comprises: a first wireless communication device that transmits a plurality of first reference signals having controlled directivity by the orthogonal frequency division multiple access (OFDMA) method in a first period; and a second wireless communication device that transmits a plurality of second reference signals having controlled directivity to the first wireless communication device in a second period, the second reference signals including information relating to directivity and corresponding to any one or more of the first reference signals received from the first wireless communication device.
Claims12
A terminal, comprising:
- circuitry, which, in operation, generates a first signal and a second signal;
- and
- a transmitter, which, in operation, transmits the first signal from a first panel antenna, and transmits the second signal from a second panel antenna based on a scheme selected from:
- a first scheme with the first signal and the second signal mapped on different frequencies and with a same timing,
- a second scheme with the first signal and the second signal mapped on partially overlapping frequencies with a same timing, and
- a third scheme with the first signal and the second signal mapped on a same frequency with a same timing, wherein,
- the first signal transmitted from the first panel antenna is transmitted with a first beam,
- the second signal arranged in the same time and transmitted from the second panel antenna is transmitted with a second beam,
- in a first mode, information on the first beam is received from a first transmission panel and information on the second beam is received from a second transmission panel, and
- in a second mode, information on the first beam and information on the second beam are received from a single transmission panel.
