1. A method for conflict avoidance in a cellular communication network, the method comprising the steps of:
transmitting a request-to-send/clear-to-send (RTS/CTS) configuration message from a base station of the cellular network to a mobile device served by the base station to cause the mobile device to activate an RTS/CTS process, wherein the RTS/CTS configuration message comprises a periodicity for transmission of the at least one CTS;
transmitting an RTS message from the base station to the mobile device requesting at least one CTS message from the mobile device, wherein the RTS message is a downlink control information (DCI) message, the DCI message is transmitted in a group-common control-resource set (CORESET) corresponding to the mobile device being addressed by the RTS message; and
receiving a CTS message at the base station from the mobile device in accordance with the RTS/CTS process;
wherein the RTS/CTS configuration message comprises an indication of a CTS signal to utilise;
the indicated CTS signal is UE-specific; and
the indication of a CTS signal indicates which shift or root of a Zadoff-Chu sequence to utilise.
