The present disclosure relates to methods and arrangements for controlling point-to-point microwave transmission on a microwave link between a first and a second microwave network node, wherein the microwave link is configured for payload data transmission at a payload data rate. The method comprises obtaining information indicative of a current data rate capability of the microwave link and comparing the current data rate capability to the configured payload data rate. When the current data rate capability is below the configured payload data rate, transmission on the microwave link is adapted to comprise transmission of dummy data on the microwave link between the first and second microwave network node.

Microwave link transmission control with transmission of low rate dummy data

A microwave transceiver comprising a data buffer, an ACM module, a PA, and an antenna. The ACM module configured to receive buffered data from the data buffer and to modulate the buffered data at a modulation format having a spectral efficiency, the PA configured to receive modulated buffered data from the ACM module, and to transmit amplified modulated buffered data, via the antenna, to a remote microwave transceiver at an output power. The modulation format is selected from a plurality of modulation formats based on a feedback signal from the remote microwave transceiver. The microwave transceiver further comprising a control module configured to monitor a buffer state of the data buffer, and to control the output power of the PA based on the buffer state.
