Abstract
The disclosure relates to a method (20) for maintaining uplink time alignment performed in a network node (12) of a communication system (10) comprising a first reception point (35) and a second reception point (36). The network node (12) is configured to control the first reception point (35) and configured to serve a communication device (14). The method (20) comprises determining (21) transmit power of the communication device (14) based on signaling from the communication device (14) received in the second reception point (36), while meeting a criterion enabling performing of an uplink time alignment measurement towards the first reception point (35). The disclosure also relates to corresponding network node, computer program and computer program product.
