CLIENT DEVICE AND NETWORK ACCESS NODE FOR HANDLING BEAM FAILURE INSTANCES

摘要

The invention relates to handling beam failure instances in a client device (100). The client device (100) monitors beam failure instances associated with beam pair links of a serving cell of a network access node (300). When a beam failure instance indication is determined, the client device (100) increments a value of a beam failure instance counter (C) and start a reset timer (T). If no further beam failure instance indication has been determined before the reset timer (T) expires, indicating that the quality of at least one beam pair link of the serving cell has improved, the value of the beam failure instance counter (C) is reset. Thereby, declaration of beam failure for short term variation in quality of the beam pair links can be postponed or avoided. The value of the reset timer (T) may be received from the network access node (300) in a control message (502).
