Resource skipping for multiple grants
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select first resources to skip in each grant occasion of multiple grant occasions for communications on a physical uplink channel. The UE may transmit uplink control information (UCI) that indicates the first resources or second resources that are not to be skipped in each grant occasion of the multiple grant occasions. The UE may transmit the communications in the multiple grant occasions using the second resources and not the first resources. Numerous other aspects are described.

transmit a single flexible uplink skipping (FUS) uplink control information (UCI) (UCI-FUS) that indicates the first resources or second resources that are not to be skipped within each CG occasion of the multiple CG occasions; and
transmit the communications in the multiple CG occasions using resources other than the first resources.

receive the communications in the multiple CG occasions; and
decode the communications in resources other than the first resources based at least in part on the single UCI-FUS.
16. The network entity of claim 15 , wherein the single UCI-FUS indicates a quantity of the multiple CG occasions.
17. The network entity of claim 15 , wherein the one or more processors are configured to:
receive a cancellation indication that indicates that the first resources are no longer skipped in CG occasions; and
decode additional communications without skipping resources.
18. The network entity of claim 15 , wherein the one or more processors are configured to transmit an indication of a skipping pattern of the first resources or bitmap of the first resources in each grant occasion.
19. The network entity of claim 15 , wherein the single UCI-FUS includes a bitmap that indicates the first resources in each CG occasion for the multiple CG occasions, and wherein the one or more processors, to decode the communications, are configured to skip decoding in the first resources.
20. The network entity of claim 15 , wherein the single UCI-FUS includes an index that corresponds to a skipping pattern of the first resources, and
wherein the one or more processors, to decode the communications, are configured to skip decoding in the skipping pattern that corresponds to the index.
21. The network entity of claim 15 , wherein the single UCI-FUS indicates one or more time and frequency bitmaps for the first resources in a specified quantity of retransmissions, and
wherein the one or more processors, to decode the communications, are configured to skip decoding in the first resources for the specified quantity of retransmissions.
22. The network entity of claim 21 , wherein the single UCI-FUS includes an index that corresponds to the one or more time and frequency bitmaps.
23. The network entity of claim 21 , wherein the one or more time and frequency bitmaps are associated with a frequency hopping scheme.
