Time-domain allocation for repetitions
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.

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 according to the determined second start and length pairs.
2. The method of claim 1 the determining of the second start and length pairs 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.

determining a second start and length pair from a table of different configured start and length entries.
4. The method of claim 1 further comprising:
determining a second start and length pair based on a slot border location.
