Abstract

Systems, methods, and apparatus for communicating transport block repetitions are disclosed. An example method performed by a wireless device includes receiving an assignment of radio resources corresponding to two or more transmissions with first start and length pairs, each transmission comprising a transport block repetition, where at least one of the first start and length pairs violates a time-domain allocation restriction. The wireless device determines second start and length pairs for the two or more transmissions such that the time-domain allocation restriction is not violated. The wireless device transmits the two or more transmissions according to the determined second start and length pairs.

Claims (50)

1. A method performed by a wireless device for sending transport block repetitions, the method comprising:

receiving an assignment of radio resources corresponding to two or more transmissions with first start and length pairs, each transmission comprising a transport block repetition, wherein at least one of the first start and length pairs violates a time-domain allocation restriction;

determining second start and length pairs for the two or more transmissions such that the time-domain allocation restriction is not violated; and

transmitting the two or more transmissions having the determined second start and length pairs according to the determined second start and length pairs;

wherein the two or more transmitted transmissions comprise a first transmission and a second transmission, the first transmission comprising a first portion and a second portion; and

wherein transmitting the first transmission further comprises transmitting such that the first portion occurs prior to a first slot border and the second portion occurs after the first slot border.

2. The method of claim 1 the determining further comprising:

for the at least one of the first start and length pairs that violates the time-domain allocation restriction, determining (i) a second start value that is larger or equal to a first start value and/or (ii) a second length value that is less than a first length value.

3. The method of claim 1 further comprising:

for the at least one of the first start and length pairs that violates the time-domain allocation restriction, determining a transport block size based on (i) a first start and length pair; or (ii) a second start and length pair.

4. The method of claim 1 further comprising:

determining a second start and length pair from a table of different configured start and length entries.

5. The method of claim 1 further comprising:

determining a second start and length pair based on a slot border location.

6. The method of claim 1 further comprising:

determining a second start and length pair based on a slot border location and a first length.

7. A computer program product comprising a non-transitory computer readable medium storing computer readable program code, the computer readable program code operable, when executed by processing circuitry to perform operations comprising:

receiving an assignment of radio resources corresponding to two or more transmissions with first start and length pairs, each transmission comprising a transport block repetition, wherein at least one of the first start and length pairs violates a time-domain allocation restriction;

determining second start and length pairs for the two or more transmissions such that the time-domain allocation restriction is not violated; and

transmitting the two or more transmissions having the determined second start and length pairs according to the determined second start and length pairs;

wherein the two or more transmitted transmissions comprise a first transmission and a second transmission, the first transmission comprising a first portion and a second portion; and

wherein transmitting the first transmission further comprises transmitting such that the first portion occurs prior to a first slot border and the second portion occurs after the first slot border.

8. The computer program product of claim 7 , the determining further comprising:

for the at least one of the first start and length pairs that violates the time-domain allocation restriction, determining (i) a second start value that is larger or equal to a first start value and/or (ii) a second length value that is less than a first length value.

9. The computer program product of claim 7 , further comprising:

for the at least one of the first start and length pairs that violates the time-domain allocation restriction, determining a transport block size based on (i) a first start and length pair; or (ii) a second start and length pair.

10. The computer program product of claim 7 , further comprising:

determining a second start and length pair from a table of different configured start and length entries.

11. The computer program product of claim 7 , further comprising:

determining a second start and length pair based on a slot border location.

12. The computer program product of claim 7 , further comprising:

determining a second start and length pair based on a slot border location and a first length.

13. A system comprising:

a non-transitory memory; and

one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising:

receiving an assignment of radio resources corresponding to two or more transmissions with first start and length pairs, each transmission comprising a transport block repetition, wherein at least one of the first start and length pairs violates a time-domain allocation restriction;

determining second start and length pairs for the two or more transmissions such that the time-domain allocation restriction is not violated; and

transmitting the two or more transmissions having the determined second start and length pairs according to the determined second start and length pairs;

wherein the two or more transmitted transmissions comprise a first transmission and a second transmission, the first transmission comprising a first portion and a second portion; and

wherein transmitting the first transmission further comprises transmitting such that the first portion occurs prior to a first slot border and the second portion occurs after the first slot border.

14. The system of claim 13 , the determining further comprising:

for the at least one of the first start and length pairs that violates the time-domain allocation restriction, determining (i) a second start value that is larger or equal to a first start value and/or (ii) a second length value that is less than a first length value.

15. The system of claim 13 , further comprising:

for the at least one of the first start and length pairs that violates the time-domain allocation restriction, determining a transport block size based on (i) a first start and length pair; or (ii) a second start and length pair.

16. The system of claim 13 , further comprising:

determining a second start and length pair from a table of different configured start and length entries.

17. The system of claim 13 , further comprising:

determining a second start and length pair based on a slot border location.

18. The system of claim 13 , further comprising:

determining a second start and length pair based on a slot border location and a first length.
