Ceasing transmission repetitions

1. An apparatus comprising:

a transmitter that transmits data to a base unit in a first transmission time interval (“TTI”), wherein the data is configured for transmission with a predetermined number of repetitions;

a receiver that receives a control signal from the base unit in a second TTI prior to completing transmission of the predetermined number of repetitions; and

a processor that:

determines whether the control signal corresponds to the data,

in response to determining that the control signal corresponds to the data, ceases transmission of at least one repetition of the data before the number of repetitions reaches the predetermined number of repetitions; and

in response to determining that the control signal fails to correspond to the data, continues to transmit at least one additional repetition of the data.

2. The apparatus of claim 1 , wherein determining whether the control signal corresponds to the data comprises the processor:

identifying a TTI offset,

calculating a TTI from the second TTI and the identified TTI offset, and

determining whether the calculated TTI matches to the first TTI,

wherein the control signal corresponds to the data in response to the calculated TTI matching the first TTI and the control signal fails to correspond to the data in response to the calculated TTI failing to match the first TTI.

3. The apparatus of claim 2 , wherein the processor identifies the TTI offset from a bit field contained in the control signal.

4. The apparatus of claim 3 , wherein the bit field contained in the control signal indicates a TTI offset from a set of TTI offsets, the set of TTI offsets being preconfigured by the base unit.

5. The apparatus of claim 2 , wherein the TTI offset is a fixed value.

6. The apparatus of claim 2 , wherein the TTI offset is preconfigured by the base unit prior to the transmitter transmitting the data.

7. The apparatus of claim 1 , wherein determining whether the control signal corresponds to the data comprises the processor:

identifying a TTI index contained in the control signal, and

determining whether the identified TTI index matches to the first TTI,

wherein the control signal corresponds to the data in response to the identified TTI index matching the first TTI and the control signal fails to correspond to the data in response to the identified TTI index failing to match the first TTI.

8. The apparatus of claim 1 , wherein the control signal comprises an indicator for indicating whether the data is successfully received,

wherein determining whether to cease at least one transmission repetition of the data before the number of repetitions reaches the predetermined number comprises the processor determining, from the indicator, whether the data is successfully received,

wherein the transmitter:

ceases at least one transmission repetition of the data before the number of repetitions reaches the predetermined number in response to the indicator indicating that the data is successfully received, and

continues repeating the data until the number of repetitions reaches the predetermined number in response to the indicator indicating that the data is not successfully received.

9. The apparatus of claim 8 , wherein determining, from the indicator, whether the data is successfully received comprises the processor reinterpreting a new data indicator (“NDI”) in the control signal, the reinterpreted NDI indicating whether the data is successfully received.

10. The apparatus of claim 1 , wherein the control signal comprises an indicator for indicating whether the data is successfully received,

wherein ceasing at least one transmission repetition of the data before the number of repetitions reaches the predetermined number is based on the processor determining, from the indicator, whether the data is successfully received,

wherein the transmitter:

ceases at least one transmission repetition of the data before the number of repetitions reaches the predetermined number in response to the indicator indicating that the data is successfully received, and

transmits the data based on scheduling of the control signal in response to the indicator indicating that the data is not successfully received.

11. The apparatus of claim 10 , wherein determining, from the indicator, whether the data is successfully received comprises the processor reinterpreting a new data indicator (“NDI”) in the control signal, the reinterpreted NDI being the indicator.

12. An apparatus comprising:

a receiver that receives data from a remote unit in a first transmission time interval (“TTI”), wherein the data is configured for transmission with a predetermined number of repetitions;

a processor that determines whether the data is successfully received; and

a transmitter that transmits a control signal, corresponding to the data, to the remote unit in a second TTI prior to the remote unit completing transmission of the data with the predetermined number of repetitions, wherein the control signal comprises an indicator for indicating whether the data is successfully received and receipt of one or more repetitions of the data is ceased subsequent to transmission of the control signal corresponding to the data.

13. The apparatus of claim 12 , wherein the control signal uses a TTI offset between the first TTI and the second TTI to indicate association between the control signal and the data.

14. The apparatus of claim 13 , wherein the control signal includes a bit field for indicating the TTI offset.

15. The apparatus of claim 14 , wherein the bit field included in the control signal indicates a TTI offset from a set of TTI offsets, the set being preconfigured for the remote unit.

16. The apparatus of claim 13 , wherein the TTI offset between the first TTI and the second TTI is a fixed value.

17. The apparatus of claim 13 , wherein the TTI offset is preconfigured for the remote unit before the remote unit transmits the data.

18. The apparatus of claim 12 , wherein the control signal includes a bit field for indicating a TTI index of the first TTI to designate association between the control signal and the data.

19. The apparatus of claim 12 , wherein the indicator for indicating whether the data is successfully received replaces a new data indicator (“NDI”) in the control signal.

20. The apparatus of claim 12 , wherein the indicator for indicating whether the data is successfully received is realized by one bit in the control signal.
