    Abstract: It is an object to provide a procedure for handling failure of a subset of serving beam pair links in wireless radio communication. A client device is configured to monitor, independently, a link quality of each serving downlink (DL) beam pair link (BPL) of the client device; detect at least one failed DL BPL based on the monitoring, where the at least one failed DL BPL is a subset of the monitored serving DL BPLs; choose an uplink, UL, BPL, where the chosen UL BPL corresponds to an available serving DL BPL of the monitored serving DL BPLs; and transmit a beam report within a predetermined time period from the detection through a non-contention-based channel using the chosen UL BPL, where the beam report indicates the at least one failed DL BPL. A client device, a network device, methods and a computer program are included.

    Abstract: A network node configured to receive a first signal in a first grant-free transmission from a client device, wherein the first signal comprises data having a first redundancy version and having a corresponding first transmission attempt number, in a first resource unit; determine an identity of the client device based on the first signal, establish that a data decoding error associated with the first grant-free transmission has occurred if the data in the first signal cannot be decoded correctly; receive a second signal in a second transmission from the client device, wherein the second signal comprises the data having a second redundancy version and having a corresponding second transmission attempt number, in a second resource unit; establish that a data decoding error associated with the second transmission has occurred if the data in the second signal cannot be decoded correctly. Corresponding client, methods, a computer program (product) are also provided.

    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.
