High frequency time domain resource allocation
A wireless device may receive one or more configuration parameters indicating entries of a time domain resource allocation table and one or more scheduling offsets. Each entry of the entries may comprise a respective slot offset. The wireless device may receive downlink control information (DCI) indicating a first entry of the entries and a first scheduling offset of the one or more scheduling offsets. The wireless device may receive downlink data in a first slot determined based on a slot offset of the first entry and the first scheduling offset.
1. A method comprising:
receiving, by a wireless device, one or more configuration parameters indicating:
entries of a time domain resource allocation table, wherein each entry of the entries comprises a respective slot offset; and

receiving downlink control information (DCI) indicating:
a first index value indicating a slot offset of a first entry of the entries; and
a second index value indicating a scheduling offset of the set of scheduling offsets, the scheduling offset comprising a ratio sub-value and a scheduling offset sub-value;
determining a first slot for receiving downlink data, based on the slot offset indicated by the first index value of the first entry and the scheduling offset indicated by the second index value, wherein the first slot is determined based on the sum of the slot offset multiplied by the ratio sub-value and the scheduling offset sub-value; and
receiving the downlink data in the first slot.

3. The method of claim 2 , wherein the starting symbol and the duration, of each entry of the entries, are jointly encoded as a start and length indicator value (SLIVs).
4. The method of claim 1 , wherein the first slot is determined based on the sum of the scheduling offset and the slot offset.
5. The method of claim 1 , wherein the one or more configuration parameters indicate the set of scheduling offsets in an order.

a second index value indicating a scheduling offset of the set of scheduling offsets, the scheduling offset comprising a ratio sub-value and a scheduling offset sub-value;
determine a first slot for receiving downlink data, based on the slot offset indicated by the first index value of the first entry and the scheduling offset indicated by the second index value, wherein the first slot is determined based on the sum of the slot offset multiplied by the ratio sub-value and the scheduling offset sub-value; and

12. The wireless device of claim 11 , wherein each entry of the entries further comprises a starting symbol and a duration, in symbols, of the downlink data.
13. The wireless device of claim 12 , wherein the starting symbol and the duration, of each entry of the entries, are jointly encoded as a start and length indicator value (SLIVs).
14. The wireless device of claim 11 , wherein the first slot is determined based on the sum of the scheduling offset and the slot offset.
15. The wireless device of claim 11 , wherein the one or more configuration parameters indicate the set of scheduling offsets in an order.

the second cell operates with a second subcarrier spacing of one or more second subcarrier spacings; and
each of the set of scheduling offsets corresponds to a pair of the one or more first subcarrier spacings and the one or more second subcarrier spacings.
18. The wireless device of claim 17 , wherein the instructions further cause the wireless device to determine a ratio between the second subcarrier spacing and the first subcarrier spacing, wherein:
the one or more configuration parameters indicate a threshold for applying the set of scheduling offsets based on the ratio; and
a first scheduling offset is zero in response to the ratio not satisfying the threshold.
19. The wireless device of claim 11 , wherein the downlink data is one or more physical downlink shared channels (PDSCHs).
