METHOD FOR ENHANCED EFFICIENCY AND/OR FLEXIBILITY IN TRANSMITTING PAYLOAD AND/OR CONTROL DATA IN DOWNLINK AND/OR UPLINK DIRECTION BETWEEN A BASE STATION ENTITY AND A USER EQUIPMENT OF A MOBILE COMMUNICATION NETWORK, SYSTEM, USER EQUIPMENT AND BASE STATION ENTITY, PROGRAM AND COMPUTER-READABLE MEDIUM

The present invention relates to a method for enhanced efficiency and/or flexibility in transmitting payload and/or control data in downlink and/or uplink direction between, on the one hand, a base station entity, and, on the other hand, a user equipment of a mobile communication network,wherein the base station entity repeatedly transmits at least one downlink control signal using a specific downlink radio transmission frequency,wherein the method comprises the following steps:-- in a first step, the user equipment - upon the user equipment transitioning from a cell search and/or cell selection and/or cell reselection state towards an idle state and/or random access enabled state with the base station entity - detects the at least one downlink control signal and the specific downlink radio transmission frequency as an initial downlink radio transmission resource, and-- in a second step, subsequent to the first step, the user equipment receives a downlink control information from the base station entity, wherein the content or value of the downlink control information indicates or defines an initial uplink radio transmission resource, wherein the initial uplink radio transmission resource is used, by the user equipment,-- to access a random access channel, in uplink direction, of the base station entity in case that the user equipment requires or is required to access a random access channel of the base station entity and/or-- to transmit control data and/or payload data in uplink direction from the user equipment to the base station entity in case that the user equipment requires or is required to transmit control data and/or payload data to the base station entity.
