Abstract
A method of operating a wireless communication device (102) configured to connect to a communications network (100) includes: monitoring for multiple downlink reference signals (411) transmitted by at least one access node of the communications network (100) using multiple downlink transmit beams (361-364), each one of the multiple downlink reference signals (411) being associated with a respective at least one of multiple random-access occasions (415-418); and accessing at least two random-access occasions (415, 418) of the multiple random-access occasions (415-418), the at least two random-access occasions (415, 418) being associated with at least two downlink reference signals (411) selected from the multiple downlink reference signals (411) based on said monitoring and establishing a multibeam operation between the wireless communication device (102) and the communications network (100), wherein the multi-beam operation is established based on at least two downlink transmit beams (361,364) used for transmitting the selected at least two downlink reference signals (411).
