One apparatus includes a transmitter that transmits data to a base unit in a first transmission time interval (“TTI”). Here, the data is configured for transmission with a predetermined number of repetitions. The apparatus includes a receiver that receives a control signal from the base unit in a second TTI. The apparatus includes a processor that determines whether the control signal corresponds to the data and, in response to the control signal corresponding to the data, determines whether to cease at least one transmission repetition of the data before the number of repetitions reaches the predetermined number. ## Claims ### Claim 1 A method performed by a user equipment (“UE”), comprising: transmitting data to a base station in a first transmission time interval (“TTI”), wherein the data is configured for transmission with a predetermined number of repetitions; receiving a control signal from the base station in a second TTI; and determining whether the control signal corresponds to the data; in response to a determination that the control signal corresponds to the data, ceasing transmission of at least one repetition of the data before a transmitted number of repetitions reaches the predetermined number in response to determining that the control signal fails to correspond to the data, continuing to transmit at least one additional repetition of the data. ### Claim 2 (depends on 1) The method of claim 1, wherein determining whether the control signal corresponds to the data comprises: 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 wherein the control signal fails to correspond to the data in response to the calculated TTI failing to match the first TTI. ### Claim 3 (depends on 2) The method of claim 2, wherein identifying the TTI offset comprises identifying the TTI offset from a bit field contained in the control signal. ### Claim 4 (depends on 3) The method 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 station. ### Claim 5 (depends on 2) The method of claim 2, wherein the TTI offset is a fixed value. ### Claim 6 (depends on 2) The method of claim 2, wherein the TTI offset is preconfigured by the base station prior to transmitting the data. ### Claim 7 (depends on 1) The method of claim 1, wherein determining whether the control signal corresponds to the data comprises: 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 wherein the control signal fails to correspond to the data in response to the identified TTI index failing to match the first TTI. ### Claim 8 (depends on 1) The method of claim 1, wherein the control signal comprises an indicator for indicating whether the data is successfully received, wherein ceasing the transmission of the at least one repetition of the data before the transmitted number of repetitions reaches the predetermined number of repetitions comprises: determining, from the indicator, whether the data is successfully received, ceasing 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 continuing to repeat the data until the number of repetitions reaches the predetermined number in response to the indicator indicating that the data is not successfully received. ### Claim 9 (depends on 8) The method of claim 8, wherein determining, from the indicator, whether the data is successfully received comprises reinterpreting a new data indicator (“NDI”) in the control signal, the reinterpreted NDI indicating whether the data is successfully received. ### Claim 10 (depends on 1) The method of claim 1, wherein the control signal comprises an indicator for indicating whether the data is successfully received, wherein ceasing the transmission of the at least one repetition of the data before the transmitted number of repetitions reaches the predetermined number of repetitions comprises: determining, from the indicator, whether the data is successfully received, ceasing 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 transmitting the data based on scheduling of the control signal in response to the indicator indicating that the data is not successfully received. ### Claim 11 (depends on 10) The method of claim 10, wherein determining, from the indicator, whether the data is successfully received comprises reinterpreting a new data indicator (“NDI”) in the control signal, the reinterpreted NDI being the indicator. ### Claim 12 A method performed by a base station, comprising: receiving data from a user equipment (“UE”) in a first transmission time interval (“TTI”), wherein the data is configured for transmission with a predetermined number of repetitions; determining whether the data is successfully received; and transmitting a control signal, corresponding to the data, to the UE in a second TTI, wherein the control signal comprises an indicator for indicating whether the data is successfully received, and wherein receipt of one or more repetitions of the data is ceased subsequent to transmission of the control signal corresponding to the data. ### Claim 13 (depends on 12) The method 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. ### Claim 14 (depends on 13) The method of claim 13, wherein the control signal includes a bit field for indicating the TTI offset. ### Claim 15 (depends on 14) The method 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 UE. ### Claim 16 (depends on 13) The method of claim 13, wherein the TTI offset between the first TTI and the second TTI is a fixed value. ### Claim 17 (depends on 13) The method of claim 13, wherein the TTI offset is preconfigured for the UE before the UE transmits the data. ### Claim 18 (depends on 12) The method 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. ### Claim 19 (depends on 12) The method of claim 12, wherein the indicator for indicating whether the data is successfully received replaces a new data indicator (“NDI”) in the control signal. ### Claim 20 (depends on 12) The method of claim 12, wherein the indicator for indicating whether the data is successfully received is realized by one bit in the control signal.
