Abstract: A method and a control unit are provided. The control unit is configured to receive a latency related measurement value; determine an antenna configuration parameter for a transceiver, wherein either select a switching based adjustment based on a configuration mode, when the received latency related measurement value exceeds a threshold level, or when the received latency related measurement value is below the threshold level, select the antenna configuration parameter for a motorised electromechanical adjustment.

Abstract: A baseband unit may be arranged to serve a plurality of remotely located network devices. Network devices are connected to the baseband unit using a fronthaul network. The disclosed network device separates signals belonging to different users before quantizing and transmits the quantized separated signals to the baseband unit. The baseband unit may monitor the quality of the link of the fronthaul network and determine the number of bits used for quantizing.

Abstract: The present application relates to a scheduler and a sender and a receiver. The scheduler (100) comprising a processor (101) and a transceiver (103); the transceiver (103) being configured to receive a first signal from a sender-receiver pair (600), wherein the sender-receiver pair (600) comprises a sender (200) and a receiver (300), the first signal comprises at least one first parameter indicating a congestion metric for a communication path between the sender (200) and the receiver (300) of the sender-receiver pair (600), and wherein the communication link is part of the communication path; and the processor (101) being configured to schedule the resources of the communication link based on the at least one first parameter.
