Abstract: A network node and a client device are described. The network node comprises a processor configured to determine a test initiation message, wherein the test initiation message indicates a set of client device identities corresponding to a set of client devices participating in a radio configuration test, a number of test packets in a sequence of test packets, and a transmission direction. The transmission direction is at least one of the group consisting of: a first transmission direction from the network node to the set of client devices and a second transmission direction from the set of client devices to the network node. A transceiver is configured to transmit the test initiation message to the set of client devices, and thereafter the transceiver either transmits or receives the sequence of test packets based on the at least one transmission direction. The transceiver also receives at least one feedback message from each client device.

Abstract: The disclosure relates to a control node. The first control node comprises a transceiver configured to receive a first set of Channel State Information, CSI, comprising CSI for radio channels between a plurality of first remote radio heads and a plurality of user devices, a processor configured to determine a first association based on the first set of CSI, wherein the first association comprises an association between the plurality of first remote radio heads and the first control node. Furthermore, the disclosure also relates to a corresponding method, a cellular wireless communication system, and a non-transitory computer readable medium.
