Abstract

Claims (44)

1. A transmitter comprising:

an interface configured for transmitting a signal in a wireless communications network cell of a wireless communications network;

a control unit configured for mapping the signal into a number of part signals and for transmitting the number of part signals with a corresponding number of associated slots of the wireless communications network cell using a corresponding number of sets of physical resources, each set comprising at least a subset of the associated plurality of physical resources of the slot;

wherein the control unit is configured for transmitting the number of part signals with a set-individual offset being individual for the set of physical resources such that each set of physical resources is shifted with respect to a synchronized start of the slot.

2. The transmitter according to claim 1 , wherein the transmitted signal is one of:

a first transmission,

a first retransmission or replica of the first transmission,

a second retransmission of the first transmission

a k-th retransmission of the first transmission

a second transmission comprising partial information of a first transmission

a second transmission comprising partial information of a first retransmission.

3. The transmitter according to claim 1 , wherein the set-individual offset is at least one of:

a configured offset;

a selected offset; and

a fixed offset.

4. The transmitter according to claim 3 , wherein the transmitter is configured for selecting the selected offset based on at least one of:

a number of retransmissions;

from a list of configured offsets;

according to a selected or configured criterion such as a device category;

based on an application executed or implemented at the transmitter;

a device type of the transmitter;

a service provided by the transmitter

according to a configured or selected (hopping) sequence; and

randomly.

5. The transmitter according to claim 1 , wherein the synchronized start of the slot refers to:

a start of a frame comprising the slot;

a feature of a frame comprising a sequence of slots; and

a start of a symbol such as an OFDM symbol wherein a sequence of symbols forms the slot.

6. The transmitter according to claim 1 , wherein the transmitter is configured for deriving a part signal from a number of repetitions of the transmission and to select the set-individual offset based on the number of retransmissions, wherein the set-individual offset indicates a number of retransmissions.

7. The transmitter according to claim 1 , wherein the transmitter is adapted to acquire at least one of the part signals to comprise a retransmission of a different part signal.

8. The transmitter according to claim 1 , wherein the transmitter is configured for dividing the signal into a number of part signal and/or to retransmit at least a part of the signal as a part signal.

9. The transmitter according to claim 1 , wherein the transmitter is configured for dynamically mapping the signal into a dynamically changing number of part signals.

10. The transmitter according to claim 1 ,

wherein the transmitter is configured for determining the set-individual offset so as to be within a lower bound and an upper bound indicated by a network controller or a base station; and/or

wherein the transmitter is configured for applying the set-individual offset according to a received signal indicating the set-individual offset; and/or

wherein the transmitter is configured for selecting the set-individual offset randomly.

11. The transmitter according to claim 1 , wherein the transmitter is configured for receiving a signal indicating a plurality of sets of offsets and for selecting one of the plurality of sets of offsets and to apply the set-individual offsets to a plurality of sets of physical resources within a frame comprising a number of slots.

12. The transmitter of claim 11 , wherein the each of the sets of offset-values comprises a unique offset-pattern associated to the set of offset-values.

13. The transmitter according to claim 1 , wherein the transmitter is configured for using the slots according to a sparse allocation scheme.

14. The transmitter according to claim 1 , wherein the transmitter is configured for using the slots according a non-orthogonal multiple access scheme.

15. A base station configured for operating a wireless communications network cell of the wireless communications network so as to provide communication in a plurality of slots, each slot comprising a plurality of associated physical resources;

wherein the base station is configured for receiving, from a plurality of transmitters a corresponding plurality of signals, each signal being mapped into a number of part signals and transmitted with the number of part signals with a corresponding number of associated slots using a corresponding number of sets of physical resources, each set comprising at least a subset of the associated plurality of physical resources of the slot, and shifted with a set-individual offset being individual for the set of physical resources with respect to a synchronized start of the slot; and wherein the base station is configured for processing the received signals.

16. The base station of claim 15 ,

wherein a network controller being in communication with the base station is configured for determining an upper bound and a lower bound of the set-individual offset; wherein the base station is configured for transmitting a signal to the transmitter, indicating the determined set-individual offset.
