Abstract
Methods for managing transmission resource conflicts, particularly for cellular networks utilised unlicensed resources. Mobile devices may be configured using higher layer signalling to respond to RTS signals if the transmission resources are available.
Claims11
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.
