1. An apparatus comprising at least one memory and at least one processor, the at least one memory storing computer executable instructions which, when performed by the at least one processor, cause the apparatus to:
receive, from an access node, a scanning message advertising support for network slicing, wherein a network accessed through the access node is divided into logical network slices, and wherein each network slice is associated with a slice identifier;
transmit an association request to the access node, wherein the association request comprises a request for a network slice, and wherein a transmitter address in the association request is a first medium access control (MAC) address of the apparatus and a receiver address in the association request is a first MAC address of the access node;
receive an association response from the access node as a response to the association request, wherein the association response indicates establishment of an association between the apparatus and the access node and comprises an information element indicating granted access to the requested network slice;
transmit, during the association, a first data frame to the access node, wherein the first data frame is addressed to the granted network slice by a MAC address of the first data frame, the MAC address of the first data frame being different from the first MAC address of the apparatus and the first MAC address of the access node; and
transmit, during the association, a second data frame to the access node, wherein the second data frame is not addressed to the granted network slice and comprises the first MAC address of the apparatus and the first MAC address of the access node.
