Claim of US Patent No. 10,219,268

1. A method for receiving transmission resources using beams, the method being performed by a wireless radio transceiver device, the method comprising:the wireless radio transceiver device receiving, using a first beam, a current transmission resource from an access node using a first transmission format;
the wireless radio transceiver device 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 wireless radio transceiver device receiving the later transmission resource at least partly using a candidate beam, the candidate beam being different from the first beam;
the wireless radio transceiver device evaluating the candidate beam by comparing performance metrics between the candidate beam and the first beam; and
the wireless radio transceiver device replacing the first beam with the candidate beam when the candidate beam has better performance metric than the first beam.
