Beam management of a radio transceiver device

A radio transceiver device for beam management of the radio transceiver device, the radio transceiver device comprising:

• a receive module configured to receive at least one taken from the group consisting of a data and a control signalling segment in a fixed reference beam, the at least one of the data and the control signalling segment being received on any of:
• Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Physical Downlink Control Channel (PDCCH), and Physical Downlink Shared Channel (PDSCH);
• an initiate module configured to initiate a beam sweep in a candidate beam set, whereby part of the at least one of the data and the control signalling segment is received in each of the beams in the candidate beam set;
• and
• an evaluate module configured to evaluate, based on the part of the at least one of the data and the control signalling segment received in each of the beams in the candidate beam set and using restored symbols of the at least one of the data and the control signalling segment received in the fixed reference beam as reference, a quality metric for each of the beams in the candidate beam set.

A radio transceiver device for beam management of the radio transceiver device, the radio transceiver device comprising processing circuitry, the processing circuitry being configured to cause the radio transceiver device to:

• receive at least one taken from the group consisting of a data and a control signalling segment in a fixed reference beam where the at least one of the data and the control signalling segment is received on any of:
• Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Physical Downlink Control Channel (PDCCH), and Physical Downlink Shared Channel (PDSCH), and whilst doing so:
• initiate a beam sweep in a candidate beam set, whereby part of the at least one of the data and the control signalling segment is received in each of the beams in the candidate beam set, and then:
• evaluate, based on the part of the at least one of the data and the control signalling segment received in each of the beams in the candidate beam set and using restored symbols of the at least one of the data and the control signalling segment received in the fixed reference beam as reference, a quality metric for each of the beams in the candidate beam set.

A non-transitory computer storage medium storing a computer program for beam management of a radio transceiver device, the computer program comprising computer code which, when run on processing circuitry of the radio transceiver device, causes the radio transceiver device to:

• receive at least one taken from the group consisting of a data and a control signalling segment in a fixed reference beam where the at least one of the data and the control signalling segment is received on any of:
• Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Physical Downlink Control Channel (PDCCH), and Physical Downlink Shared Channel (PDSCH), and whilst doing so:
• initiate a beam sweep in a candidate beam set, whereby part of the at least one of the data and the control signalling segment is received in each of the beams in the candidate beam set;
• and then:
• evaluate, based on the part of the at least one of the data and the control signalling segment received in each of the beams in the candidate beam set and using restored symbols of the at least one of the data and the control signalling segment received in the fixed reference beam as reference, a quality metric for each of the beams in the candidate beam set.
