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 preamble sequence sending method and apparatus are provided. The method includes sending, by user equipment (UE), a first preamble sequence according to a first transmit power and using a repetition factor N1; if the UE fails to receive, in a preset time period after the first preamble sequence is sent, a response message that is sent by a network-side device and that is corresponding to the first preamble sequence, switching, by the UE, to a next repetition factor N2, where a quantity of consecutive sending times indicated by the next repetition factor N2 is greater than a quantity of consecutive sending times indicated by the repetition factor N1; and sending, by the UE, a second preamble sequence according to a second transmit power and using the next repetition factor N2.

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.
