Patent ID: 10306651

Abstract:
A method (20) of scheduling performed by a network node (3) is disclosed. The network node (3) comprises a distributed local oscillator architecture in which elements (181, . . . , 18i, . . . , 18N) of an antenna array (14) have at least partly uncorrelated local oscillator signals, and the network node (3) has wireless connectivity to at least two transmitter nodes (2a, 2b). The method (20) comprises calculating (21) a phase noise value between one or more layers received in each element (181, . . . , 18i, . . . , 18N) from a first transmitter node (2a) and one or more layers received in each element (181, . . . , 18i, . . . , 18N) from a second transmitter node (2b), and determining (22) a scheduling allocation for the at least two transmitter nodes (2a, 2b), taking the calculated phase noise value into account. A network node (3), computer program and computer program product are also provided.
