Abstract
A method for establishing a wireless communication link between a first communication device having a beam antenna to be steered to different positions and a second communication device. The method includes transmitting a link request signal from the first communication device to the second communication device via the beam antenna. The link request signal includes information relating to a current position of the beam antenna. The method further includes obtaining, in case the link request signal is received in the second communication device, channel quality information representative of a current transmission path.
Claims18
A method for establishing a wireless transmission link between a first communication device and a second communication device, said first communication device having an antenna beam operable at different beam directions, the method comprising
- transmitting a link request signal from said first communication device to said second communication device via said antenna beam, wherein said link request signal comprises information relating to a current beam direction of the antenna beam;
- and
- obtaining, in case said link request signal is received in said second communication device, channel quality information representative of a current transmission path.
A method for establishing a wireless transmission link between a first communication device and a second communication device, said first communication device having an antenna beam with a beam direction, the method comprising
- transmitting a link request signal from said first communication device to said second communication device via said antenna beam, wherein said link request signal comprises information relating to a current beam direction of the antenna beam;
- and
- obtaining, in case said link request signal is received in said second communication device, channel quality information representative of a current transmission path, wherein
- said antenna beam is operated to different directions and a link request signal is transmitted for each direction, each of the link request signals comprising information relating to the respective direction of said antenna beam via which it is transmitted.
A transmitting device for transmitting signals in a wireless communication system, comprising:
- an antenna beam operable at different beam directions;
- and
- a signal transmitting unit configured to transmit a link request signal to a receiving device via said antenna beam, wherein said link request signal comprises information relating to a current direction of the antenna beam.
A transmitting device for transmitting signals in a wireless communication system, comprising:
- an antenna beam with a beam direction;
- a signal transmitting unit configured to transmit a link request signal to a receiving device via said antenna beam, wherein said link request signal comprises information relating to a current direction of the antenna beam, wherein
- said signal transmitting unit transmits link request signals comprising information relating to each direction of said antenna beam, and
- when an antenna operating unit is configured to operate said antenna beam at different beam directions, a link request signal is transmitted for each direction, each of the link request signals comprising information relating to the respective directions of said antenna beam via which it is transmitted.
A transmitting device for transmitting signals in a wireless communication system, comprising
- an antenna beam operable at different beam directions;
- and
- a signal transmitter configured to transmit a link request signal to a receiving device via said antenna beam, wherein said link request signal comprises information relating to a current direction of the antenna beam.
