10. A wireless device adapted to establish a connection for data transmission between a network node and the wireless device in a wireless communications network, the wireless device being adapted to be fixed, the wireless device being fixed meaning the wireless device is always being served by the same one or more access points, the wireless device comprising:
processing circuitry; memory containing instructions executable by the processing circuitry whereby the wireless device is operative to:
indicate that the wireless device is fixed, the indicating comprising one of indicating to a core network node that the wireless device is fixed by requesting to perform relaxed measurements and indicating to the network node the wireless device is fixed; receive an indication from the network node indicating a Timing Advance (TA) which is obtained without performing Uplink (UL) transmission, the TA being based on a distance between the network node and the wireless device, the wireless device comprised in a group of fixed wireless devices that are within a predetermined proximity of each other, the TA being applied to all wireless devices within the group; perform Radio Resource Control (RRC) signaling with the network node using the indicated TA; and establish the connection for data transmission between the network node and the wireless device based on RRC signaling, the instructions being such that the wireless device is operative to initiate the establishing of the connection for data transmission between the network node and the wireless device without any preamble based Random Access Channel (RACH) procedures.
