Abstract
There is provided mechanisms for configuring reception of beam reports. A method is performed by a network node. The method comprises scheduling wireless devices to provide beam reports in a common time/frequency resource. The method comprises monitoring reception of the beam reports from the wireless devices in the common time/frequency resource using a cell-covering reception beam created by an analog beamforming network.

A method for configuring reception of beam reports, the method being performed by a network node, the method comprising:
- scheduling wireless devices to provide beam reports in a common time/frequency resource;
- monitoring reception of the beam reports from the wireless devices in the common time/frequency resource using a cell-covering reception beam created by an analog beamforming network;
- transmitting reference signal scheduling information indicating at least i) a first time at which the network node will use a first transmission beam to transmit a reference signal and ii) a second time at which the network node will use a second transmission beam to transmit a reference signal, wherein the second transmission beam is different than the first transmission beam;
- and
- in accordance with the reference scheduling information, using the first transmission beam to transmit a reference signal at the first time and using the second transmission beam to transmit a reference signal at the second time, wherein
- monitoring reception of the beam reports comprises receiving a first beam report transmitted by a first wireless device, and
- the first beam report identifies the first transmission beam.
A method performed by a wireless device, the method comprising:
- the wireless device receiving scheduling information transmitted by a network node, the scheduling information for scheduling the wireless device to provide a beam report during a particular common time period selected by the network node;
- the wireless device receiving a first reference signal transmitted by the network node, wherein the network node transmitted the reference signal using a first transmit beam;
- the wireless device generating a beam report after receiving the first reference signal;
- and
- the wireless device transmitting the beam report to the network node in the particular common time period selected by the network node, wherein
- the beam report comprises information identifying the first transmit beam.
A network node for configuring reception of beam ports, the network node comprising:
- processing circuitry;
- and
- a storage medium storing instructions that, when executed by the processing circuitry, cause the network node to:
- schedule wireless devices to provide beam reports in a common time/frequency resource;
- monitor reception of the beam reports from the wireless devices in the common time/frequency resource using a cell-covering reception beam created by an analog beamforming network;
- transmit reference signal scheduling information indicating at least i) a first time at which the network node will use a first transmission beam to transmit a reference signal and ii) a second time at which the network node will use a second transmission beam to transmit a reference signal, wherein the second transmission beam is different than the first transmission beam;
- and
- in accordance with the reference scheduling information, use the first transmission beam to transmit a reference signal at the first time and use the second transmission beam to transmit a reference signal at the second time, wherein
- the beam reports comprises a first beam report transmitted by a first wireless device, and
- the first beam report identifies the first transmission beam.
A wireless device for receiving configuration of reception of beam reports, the wireless device comprising:
- processing circuitry;
- and
- a storage medium storing instructions that, when executed by the processing circuitry, cause the wireless device to:
- process scheduling information transmitted by a network node, the scheduling information for scheduling the wireless device to provide a beam report during a particular common time period selected by the network node;
- process a first reference signal transmitted by the network node, wherein the network node transmitted the reference signal using a first transmit beam;
- generate a beam report after receiving the first reference signal;
- and
- transmit the beam report to the network node in the particular common time period selected by the network node, wherein
- the beam report comprises information identifying the first transmit beam.
A computer program product comprising a non-transitory computer readable medium storing a computer program for configuring reception of beam ports, the computer program comprising computer code which, when run on processing circuitry of a network node, causes the network node to:
- schedule wireless devices to provide beam reports in a common time/frequency resource;
- monitor reception of the beam reports from the wireless devices in the common time/frequency resource using a cell-covering reception beam created by an analog beamforming network;
- transmit reference signal scheduling information indicating at least i) a first time at which the network node will use a first transmission beam to transmit a reference signal and ii) a second time at which the network node will use a second transmission beam to transmit a reference signal, wherein the second transmission beam is different than the first transmission beam;
- and
- in accordance with the reference scheduling information, use the first transmission beam to transmit a reference signal at the first time and use the second transmission beam to transmit a reference signal at the second time, wherein
- the beam reports comprises a first beam report transmitted by a first wireless device, and
- the first beam report identifies the first transmission beam.
A computer program product comprising a non-transitory computer readable medium storing a computer program for receiving configuration of reception of beam reports, the computer program comprising computer code which, when run on processing circuitry of a wireless device, causes the wireless device to:
- process scheduling information transmitted by a network node, the scheduling information for scheduling the wireless device to provide a beam report during a particular common time period selected by the network node;
