monitor a search space for an UL cancellation indication; detect an UL cancellation indication in the search space; and in response, cancel at least a portion of a scheduled UL transmission. ## Claims ### Claim 1 Baseband circuitry, configured to: receive a configuration signaling to monitor for uplink (UL) cancellation indications; monitor, based on the configuration signaling, a search space for an UL cancellation indication; detect an UL cancellation indication in the search space, wherein the UL cancellation indication identifies physical resources that span beyond a scheduled physical uplink shared channel (PUSCH) transmission; and in response, cancel UL transmissions that overlap with the physical resources identified by the UL cancellation indication including at least a portion of the scheduled PUSCH transmission. ### Claim 2 (depends on 1) The baseband circuitry of claim 1, wherein the scheduled PUSCH transmission is associated with a Type 1 or Type 2 configured grant. ### Claim 3 (depends on 1) The baseband circuitry of claim 1, wherein the UL cancellation indication comprises an X by Y bitmap of physical resources, wherein X is greater than one and corresponds to a number of time partitions and Y is greater than one and corresponds to a number of frequency partitions. ### Claim 4 (depends on 1) The baseband circuitry of claim 1, further configured to monitor for UL cancellation indications in a group-common search space associated with a Control Resource Set (CORESET). ### Claim 5 (depends on 1) The baseband circuitry of claim 1, further configured to: cancel a portion of the scheduled PUSCH transmission specified by the UL cancellation indication. ### Claim 6 (depends on 1) The baseband circuitry of claim 1, further configured to: cancel all scheduled UL transmissions that overlap with physical resources specified by the UL cancellation indication. ### Claim 7 (depends on 1) The baseband circuitry of claim 1, further configured to: detect that a trigger condition has been met; and in response, commence monitoring of the search space for cancellation indications. ### Claim 8 (depends on 7) The baseband circuitry of claim 7, further configured to detect that the trigger condition has been met when an UL grant for scheduling a PUSCH transmission is received. ### Claim 9 (depends on 1) The baseband circuitry of claim 1, further configured to: receive a second UL grant for a transport block (TB) associated with a scheduled UL transmission resulting from a first UL grant; and in response, cancel the scheduled UL transmission. ### Claim 10 (depends on 9) The baseband circuitry of claim 9, further configured to cause transmission of the TB according to the second UL grant. ### Claim 11 (depends on 9) The baseband circuitry of claim 9 further configured to determine that the second UL grant and the first UL grant have a same hybrid automatic repeat request (HARQ) process identifier associated with the TB, and in response, cancel the scheduled UL transmission. ### Claim 12 (depends on 1) The baseband circuitry of claim 1, further configured to: determine a length of the scheduled PUSCH transmission; and refrain from monitoring the search space when the length falls below a threshold. ### Claim 13 (depends on 1) The baseband circuitry of claim 1, further configured to: transmit a portion of the scheduled PUSCH transmission that does not overlap with physical resources specified by the UL cancellation indication. ### Claim 14 (depends on 1) The baseband circuitry of claim 1, further configured to: receive an UL grant; schedule the PUSCH transmission based on the UL grant; determine, based on the UL grant, that the UL grant is prioritized; and receiving the UL cancellation indication for the scheduled PUSCH transmission; and cause transmission of the scheduled PUSCH transmission. ### Claim 15 (depends on 14) The baseband circuitry of claim 14, further configured to, in response to receiving the UL cancellation indication, cancel a subsequent scheduled repeat UL transmission that resulted from the UL grant. ### Claim 16 (depends on 14) The baseband circuitry of claim 14, further configured to determine that the UL grant is prioritized based on a value of a DCI field of the UL grant. ### Claim 17 A user equipment, comprising a memory and a baseband processor configured to, when executing instructions stored in the memory, cause the UE to receive a configuration signaling to monitor for uplink (UL) cancellation indications; monitor, based on the configuration signaling, a search space for an UL cancellation indication; detect an UL cancellation indication in the search space, wherein the UL cancellation indication identifies physical resources that span beyond a scheduled physical uplink shared channel (PUSCH) transmission; and in response, cancel UL transmissions that overlap with the physical resources identified by the UL cancellation indication including at least a portion of the scheduled PUSCH transmission. ### Claim 18 (depends on 17) The UE of claim 17, wherein the UL cancellation indication comprises an X by Y bitmap of physical resources, wherein X is greater than one and corresponds to a number of time partitions and Y is greater than one and corresponds to a number of frequency partitions. ### Claim 19 A method, comprising: receiving a configuration signaling to monitor for uplink (UL) cancellation indications; monitoring, based on the configuration signaling, a search space for an UL cancellation indication; detecting an UL cancellation indication in the search space, wherein the UL cancellation indication identifies physical resources that span beyond a scheduled physical uplink shared channel (PUSCH) transmission; and in response, canceling UL transmissions that overlap with the physical resources identified by the UL cancellation indication including at least a portion of the scheduled PUSCH transmission. ### Claim 20 (depends on 19) The method of claim 19, wherein the UL cancellation indication comprises an X by Y bitmap of physical resources, wherein X is greater than one and corresponds to a number of time partitions and Y is greater than one and corresponds to a number of frequency partitions.
