Abstract
There is provided determination of a beam configuration between a first radio transceiver device and a second radio transceiver device. The first radio transceiver device performs beam searching by transmitting a first sounding signal in all transmit beam configurations in a set of transmit beam configurations; and receiving, from the second radio transceiver device, a second sounding signal in all receive beam configurations in a set of receive beam configurations. The first radio transceiver device determines a beam configuration based on the receive beam configuration in the set of receive beam configurations in which the second sounding signal having best predetermined metric was received.
Claims23
A method for determining a beam configuration between a first radio transceiver device and a second radio transceiver device, the method being performed by the first radio transceiver device and comprising the steps of:
- performing beam searching without relying on previously established control channels for feedback information by:
- deciding, in a mutually blind beam configuring between the first radio transceiver device and the second radio transceiver device, in what order a transmitting by the first radio transceiver device and a receiving by the first radio transceiver device will be performed;
- the first radio transceiver device performing the transmitting and the receiving in the decided order,
- wherein the transmitting comprises transmitting a first sounding signal in all transmit beam configurations in a set of transmit beam configurations;
- and
- wherein the receiving comprises receiving, from the second radio transceiver device, a second sounding signal in all receive beam configurations in a set of receive beam configurations;
- and
- determining a beam configuration for the first radio transceiver device based on the receive beam configuration in the set of receive beam configurations in which said second sounding signal having best predetermined metric was received.
A radio transceiver device for determining a beam configuration between the radio transceiver device and a second radio transceiver device, the radio transceiver device comprising a processing unit configured to cause the radio transceiver device to:
- perform beam searching without relying on previously established control channels for feedback by:
- deciding, in a mutually blind beam configuring between the first radio transceiver device and the second radio transceiver device, in what order a transmitting by the radio transceiver device and a receiving by the radio transceiver device will be performed;
- performing the transmitting and the receiving in the decided order,
- wherein the transmitting comprises transmitting a first sounding signal in all transmit beam configurations in a set of transmit beam configurations;
- and
- wherein the receiving comprises receiving, from the second radio transceiver device, a second sounding signal in all receive beam configurations in a set of receive beam configurations;
- and
- determine a beam configuration for the first radio transceiver device based on the receive beam configuration in the set of receive beam configurations in which said second sounding signal having best predetermined metric was received.
A nontransitory computer readable storage medium comprising a computer program for determining a beam configuration between a radio transceiver device and a second radio transceiver device, the computer program comprising computer code which, when run on a processing unit of the radio transceiver device, causes the radio transceiver device to:
- perform beam searching without relying on previously established control channels for feedback by:
- deciding, in a mutually blind beam configuring between the first radio transceiver device and the second radio transceiver device, in what order a transmitting by the radio transceiver device and a receiving by the radio transceiver device will be performed;
- the radio transceiver device performing the transmitting and the receiving in the decided order,
- wherein the transmitting comprises transmitting a first sounding signal in all transmit beam configurations in a set of transmit beam configurations;
- and
- wherein the receiving comprises receiving, from the second radio transceiver device, a second sounding signal in all receive beam configurations in a set of receive beam configurations;
- and
- determine a beam configuration for the first radio transceiver device based on the receive beam configuration in the set of receive beam configurations in which said second sounding signal having best predetermined metric was received.
