Abstract
There is provided mechanisms for receiving transmission resources using beams. A method is performed by a wireless radio transceiver device. The method comprises receiving, using a first beam, a current transmission resource from an access node using a first transmission format. The method comprises transmitting an indicator to the access node to use a second transmission format for a later transmission resource to be transmitted to the wireless radio transceiver device. The method comprises receiving the later transmission resource at least partly using a candidate beam, where the candidate beam is different from the first beam.
