Method and apparatus for uplink cancellation indication

A non-transitory computer-readable storage medium of a terminal device storing thereon executable instructions that, as a result of being executed by one or more processors of the terminal device, cause the terminal device to:

• receive an uplink (UL) grant, wherein the UL grant schedules a Physical Uplink Shared Channel (PUSCH), wherein a frequency resource for the PUSCH is allocated within an active UL Bandwidth Part (BWP) of the terminal device, and wherein the frequency resource is allocated using a physical resource block (PRB) index of the active UL BWP;
• receive a UL cancellation indication (CI), wherein the UL CI indicates a UL resource in a reference UL resource, wherein the reference UL resource is allocated within a carrier including at least the active UL BWP, and wherein the reference UL resource is allocated using a common resource block (CRB) index of the carrier;
• define a starting symbol of the reference UL resource;
• determine whether the UL resource overlaps with the PUSCH to yield a determination;
• and
• when the determination indicates that the UL resource overlaps with the PUSCH, cancel the PUSCH, wherein:
• the starting symbol is defined as a first symbol after a time duration from an end of the UL CI, and
• the time duration is defined based on (i) a first time duration of minimum processing for decoding the UL grant and preparing the PUSCH and (ii) a second time duration configured by a Next-Generation Node B (gNB).

A system, comprising:

• one or more processors;
• and
• memory storing thereon instructions that, as a result of being executed by the one or more processors, cause the system to:
• receive an uplink (UL) grant, wherein the UL grant schedules a Physical Uplink Shared Channel (PUSCH), wherein a frequency resource for the PUSCH is allocated within an active UL Bandwidth Part (BWP) of the system, and wherein the frequency resource is allocated using a physical resource block (PRB) index of the active UL BWP;
• receive a UL cancellation indication (CI), wherein the UL CI indicates a UL resource in a reference UL resource, wherein the reference UL resource is allocated within a carrier including at least the active UL BWP, and wherein the reference UL resource is allocated using a common resource block (CRB) index of the carrier;
• define a starting symbol of the reference UL resource;
• determine whether the UL resource overlaps with the PUSCH to yield a determination;
• and
• when the determination indicates that the UL resource overlaps with the PUSCH, cancel the PUSCH, wherein:
• the starting symbol is defined as a first symbol after a time duration from an end of the UL CI, and
• the time duration is defined based on (i) a first time duration of minimum processing for decoding the UL grant and preparing the PUSCH and (ii) a second time duration configured by a Next-Generation Node B (gNB).
