Abstract: A method of determining a passive Round Trip Time, RTT, delay in a telecommunications system for exchanging data packets in accordance with a data transmission protocol between a first device and a second device. The first and second devices are identified by first and second device identifications, respectively. The data packets include an address part including a source address and a destination address. The method is performed in a node by modifying the address part of a received data packet from the first device, and creating a first timestamp before transmitting the modified data packet to the second device. Upon receiving, at the node, from the second device in response to the modified data packet, a data packet having the modified address part of the modified data packet, the node creates a second timestamp that provides for passively measuring the RTT delay.

Abstract: A method performed by a network node for beam management. The network node receives one or more quality values from a User Equipment (UE). The one or more quality values are measured by the UE on first reference signals transmitted by the network node in respective one or more beams in a first set of candidate beams. The A serving beam is selected out of the first set of candidate beams based on the received quality values for data communication with the UE. The network node creates a rule related to signal quality. The network node obtains one or more second quality values related to respective subsequent messages transmitted to the UE in the selected serving beam. As long as the rule is fulfilled with respect to the second quality value, the network node transmits one or more further subsequent messages only in the serving beam.
