Reception beam selection for a radio access network
There is disclosed a method of operating a receiving radio node in a radio access network. The method includes selecting, from a set of defined reception beams formed by reception beamforming, one or more beams for processing, wherein selecting is based on a beam quality representation determined for one or more beams of the set for one or more transmitters.
1. A method of operating a receiving radio node in a radio access network, the method comprising:
selecting, from a set of defined reception beams formed by reception beamforming, at least one beam for processing, the selecting being based on:
a beam quality measurement, BQM, representation determined for at least one beam of the set of defined reception beams for at least one transmitter of the receiving radio node; and
a combined beam quality measurement, CBQM, representation determined for at least a subset of the set of defined reception beams, the subset being associated with at least one transmission stream, the CBQM being determined based on a quality of service parameter associated with the at least one transmission stream.
2. The method according to claim 1 , wherein the BQM is further determined for at least one of multiple layers of transmission from the at least one-transmitter.
3. The method according to claim 1 , wherein the BQM pertains to at least one of:
received signal strength;
received signal quality;
covariance of received signaling; and
direction of received signaling.
4. The method according to claim 1 , wherein the BQM is associated to a transmitter.
5. The method according to claim 1 , wherein the BQM is associated to a transmitter, and represents a combination of a plurality of beam quality metrics for at least one beam.
6. The method according to claim 1 , wherein the selecting is further performed based on at least one scheduling characteristic.
7. A receiving radio node for a radio access network, the receiving radio node being configured to:
select, from a set of defined reception beams formed by reception beamforming, at least one beam for processing, the selecting being based on:
a beam quality measurement, BQM, representation determined for at least one beam of the set of defined reception beams for at least one transmitter of the receiving radio node; and
a combined beam quality measurement, CBQM, representation determined for at least a subset of the set of defined reception beams, the subset being associated with at least one transmission stream, the CBQM being determined based on a quality of service parameter associated with the at least one transmission stream.
8. The receiving radio node according to claim 7 , wherein the BQM is further determined for
at least one of multiple layers of transmission from the at least one transmitter.
9. The receiving radio node according to claim 7 , wherein the BQM pertains to at least one of:
received signal strength;
received signal quality;
covariance of received signaling; and
direction of received signaling.
10. The receiving radio node according to claim 7 , wherein the BQM is associated to a transmitter.
11. The receiving radio node according to claim 7 , wherein the BQM is associated to a transmitter, and represents a combination of a plurality of beam quality metrics for at least one beam.
12. The receiving radio node according to claim 7 , wherein the selecting is further performed based on at least one scheduling characteristic.
13. A computer storage medium storing an executable computer program having instructions that, when executed, cause processing circuitry to at least of control and perform a method of operating a receiving radio node in a radio access network, the method comprising:
selecting, from a set of defined reception beams formed by reception beamforming, at least one beam for processing, the selecting being based on:
a beam quality measurement, BQM, representation determined for at least one beam of the set of defined reception beams for at least one transmitter of the receiving radio node; and
a combined beam quality measurement, CBQM, representation determined for at least a subset of the set of defined reception beams, the subset being associated with at least one transmission stream, the CBQM being determined based on a quality of service parameter associated with the at least one transmission stream.
