Method and apparatus for uplink implementation

A non-transitory, computer-readable storage medium storing computer-executable instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:

• receive an uplink (UL) grant scheduling a Physical Uplink Shared Channel (PUSCH), a frequency resource for the PUSCH being allocated within an active UL Bandwidth Part (BWP) of the UE;
• receive a UL cancellation indication (CI) indicating a UL resource in a reference UL resource, the reference UL resource being allocated within a carrier including at least the active UL BWP;
• define a starting symbol of the reference UL resource;
• and
• in a case that the UL CI is received after the UL grant,
• determine whether the UL resource overlaps the PUSCH, and
• in a case that the UL resource overlaps 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,
• the time duration is defined based on a first time duration of minimum processing for decoding the UL grant and preparing the PUSCH and a second time duration configured by a Next-Generation Node B (gNB), and
• the first time duration is determined based on a smallest subcarrier spacing (SCS) of a downlink (DL) in which a Physical Downlink Control Channel (PDCCH) carrying the UL CI was received and a smallest SCS of configured UL BWPs of the carrier.

A user equipment (UE) for handling an uplink (UL) cancellation indication (CI), the UE comprising:

• one or more processors;
• and
• at least one memory storing computer-executable instructions that, when executed by the one or more processors, cause the UE to:
• receive a UL grant scheduling a Physical Uplink Shared Channel (PUSCH), a frequency resource for the PUSCH being allocated within an active UL Bandwidth Part (BWP) of the UE;
• receive the UL CI, the UL CI indicating a UL resource in a reference UL resource, the reference UL resource being allocated within a carrier including at least the active UL BWP;
• define a starting symbol of the reference UL resource;
• and
• in a case that the UL CI is received after the UL grant,
• determine whether the UL resource overlaps the PUSCH, and
• in a case that the UL resource overlaps 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,
• the time duration is defined based on a first time duration of minimum processing for decoding the UL grant and preparing the PUSCH and a second time duration configured by a Next-Generation Node B (gNB), and
• the first time duration is determined based on a smallest subcarrier spacing (SCS) of a downlink (DL) in which a Physical Downlink Control Channel (PDCCH) carrying the UL CI was received and a smallest SCS of configured UL BWPs of the carrier.
