1. A method, performed by a wireless device for performing a temporally distributed network access procedure on an uplink carrier to access a wireless communication network, the method comprising:
receiving network access configuration information broadcast from the network;
based only on the broadcast network access configuration information, determining a plurality of access opportunities, in the time domain, on which network access signalling is possible on the uplink carrier;
based on the network access configuration information and a parameter unique to the wireless device, wherein the parameter is configured independently of the network, determining a subset of the plurality of possible access opportunities in which the wireless device is permitted to transmit network access signalling on the uplink carrier, such that the network is unaware of the determined subset; and
transmitting network access signalling on the uplink carrier only during the subset of permitted access opportunities.
