Claim 7:
8. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus to perform:
determining an initial waiting time at an access device of a network;
transmitting an information indicating the determined initial waiting time to a terminal device for setting a time offset for a retransmission with a selected resource indicator for a non-scheduled access to the network;
receiving a first scheduled transmission from the terminal device;
sending a feedback to the terminal device;
wherein the feedback comprises at least one of the following indications:
an indicator of a layer 2 error caused by a random access channel resource collision of two or more terminal devices;
an indication of an acknowledgement or an indication that new data can be sent; and
an indication of a non-acknowledgement or the lack of a new data indication or an indication that no new data shall be sent,

wherein the feedback is for the terminal device to adjust the time offset based on the feedback by using a parameter, and
wherein the time offset is adjusted by incrementing the parameter if the feedback indicates a non-acknowledgement for layer 2; by decrementing the parameter if the feedback indicates an acknowledgement; and wherein the time offset is maintained if the feedback indicates a non-acknowledgement for layer 1.
