1. A method, performed by a wireless communications device for accessing a predefined system bandwidth within an unlicensed radio frequency band, the wireless communications device being configured, by a wireless communications network comprising a network node, to operate within the predefined system bandwidth which comprises a plurality of bandwidth parts configured by the wireless communications network, the method comprising:
receiving, from the network node, downlink control information (DCI) including an explicit indication requesting the wireless communications device to make a prioritization among the plurality of bandwidth parts;
prioritizing, in response to receiving the indication, among the plurality of bandwidth parts without prioritization information from the network node;
selecting at least one bandwidth part of the plurality of bandwidth parts in accordance with the prioritization; and
accessing the at least one bandwidth part selected.
