Abstract

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 (S41) information indicative of a current data rate capability of the microwave link andcomparing (S43) 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 (S47) to comprise transmission of dummy data on the microwave link between the first and second microwave network node.

Description

technical field [0001] The present disclosure relates to methods and arrangements for transmission control in microwave links, in particular microwave links configured for adaptive spectral efficiency of data transmission. Background technique [0002] In microwave communication networks, it is always a challenge to obtain good performance due to the changing conditions in the physical environment in which microwave links are deployed. [0003] Traditionally, microwave links have been configured for transmission at a fixed data rate (i.e., using a fixed modulation and coding scheme); or in other words, microwave links are set up for a fixed scenario with a margin to ensure Specific data transfer capacity and link availability. [0004] Fixed modulation and coding schemes are usually set for worst-case scenarios that represent transmission conditions that rarely occur. When the transmission conditions of the fixed-rate microwave link are improved, there is no impact on the ...
