Abstract: A processing device for a client device obtains a set of reference signal configurations for a set of serving downlink beams. Each reference signal configuration of the set of reference signal configurations is associated with a respective serving downlink beam of the set of serving downlink beams. Each reference signal configuration of the set of reference signal configurations also includes a reference signal periodicity. The processing device further performs beam monitoring on the set of serving downlink beams based on the reference signal periodicities of the set of reference signal configurations.

Abstract: The disclosure relates to performing phase compensation at a transmitter. A processing device for a network access node generates a phase compensated modulation symbol based on at least one first modulation symbol and at least on one of a frequency offset parameter and a time offset parameter. The frequency offset parameter may be determined based on an offset between a reference frequency f0 and a DC (0 Hz) frequency such that the frequency offset parameter corresponds to the reference frequency f0. Also, the reference frequency f0 can be at least partly based on the carrier of up-conversion frequency used by the processing device and the reference frequency f0 can be the carrier for up-conversion frequency. The phase compensated symbol is transmitted to a receiver, such as a client device. Furthermore, the disclosure also relates to corresponding methods and a computer program.

Abstract: According to a first aspect, a client device is configured to: transmit a beam report, for example to a network device, wherein the beam report comprises information about a set of N transmit, Tx, beams in a downlink and measurement values related to the N Tx beams; obtain information about selected K Tx beams being a subset of the set of N Tx beams; obtain mapping information between K indicators and the selected K Tx beams, wherein each of the K indicator identifies one of the selected K Tx beams; and receive, for example from the network device, a downlink, DL, signal using the obtained information about the selected K Tx beams and the mapping information. According to another aspect a network device is provided. According to another aspects methods of operating the devices are provided and a computer program.

Abstract: A first communication device receives a first signal, the first signal being transmitted by a second communication device using a first spatial-domain transmit filter; determines, based on the first signal, a Line-of-Sight characteristic associated with the first spatial-domain transmit filter, and transmits a first control message to the second communication device, the first control message indicating the Line-of-Sight characteristic associated with the first spatial-domain transmit filter.
