Abstract

The present invention relates to a wireless transmitter comprising a transmitter radio unit working a wireless transmitter comprising a transmitter radio unit working in the millimeter wave frequency band using a directional antenna and a bidirectional radio unit working in a frequency range different from said transmitter radio unit and using an omnidirectional antenna. The invention further relates to a wireless receiver and a wireless relay.

Claims

1. A wireless transmitter comprising

a transmitter radio unit working in the millimeter wave frequency band using a directional antenna and

a bidirectional radio unit working in a frequency range different from said transmitter radio unit and using an omnidirectional antenna.

2. The wireless transmitter defined in claim 1, wherein the directional antenna provides one or more beams.

3. The wireless transmitter defined in claim 1, further comprising a radio link control unit, RLC, to control said radio units.

4. The wireless transmitter defined in claim 3, further comprising a sounding channel frame generator for sending channel sounding frames transmission messages via the transmitter radio unit to determine channel conditions of an active antenna beam combination and other possible ones with a wireless receiver or a wireless relay.

5. The wireless transmitter defined in claim 4, whereby the bidirectional radio unit is adapted to receive channel measurement values from the wireless receiver or wireless relay.

6. The wireless transmitter defined in claim 5, further comprising a ranking list database comprising a table containing the channel measurement values of the active antenna beam combination and other possible ones.

7. A wireless receiver comprising

a receiver radio unit working in the millimeter wave frequency band using a directional antenna and

a bidirectional radio unit working in a frequency range different from said receiver radio unit and using an omnidirectional antenna.

8. The wireless receiver defined in claim 7, wherein the directional antenna provides one or more beams.

9. The wireless receiver defined in claim 7, further comprising a radio link control unit, RLC, to control said radio units.

10. The wireless receiver defined in claim 9, further comprising a channel measurement unit for collecting channel measurement values of an active antenna beam combination and other possible ones with a wireless transmitter or a wireless relay.

11. The wireless receiver defined in claim 10, whereby the bidirectional radio unit is adapted to send channel measurement values to the wireless transmitter or wireless relay.

12. The wireless receiver defined in claim 11, further comprising a ranking list generator adapted to generate and rank the channel measurement values of the active antenna beam combination and other possible ones.

13. A wireless relay comprising

a receiver radio unit working in the millimeter wave frequency hand using a first directional antenna,

a transmitter radio unit working in the millimeter wave frequency band using a second directional antenna different form said first directional antenna and

a bidirectional radio unit working in a frequency range different from said receiver radio unit and said transmitter radio unit and using an omnidirectional antenna.

14. The wireless relay defined in claim 13, wherein each of the directional antennas may provide one or more beams.

15. The wireless relay defined in claim 13, further comprising a radio link control unit, RLC, to control said receiver and transmitter radio units.

16. The wireless relay defined in claim 15, whereby the bidirectional radio unit is adapted to forward channel measurement values from a wireless receiver or another relay to a wireless transmitter or said another relay.

17. The wireless relay defined in claim 16, whereby the receiver radio unit and the transmitter radio unit are adapted to forward channel sounding frames transmission messages from the wireless transmitter or another relay to the wireless receiver or said another relay.
