Description

Resource Cancellation Method and User Equipment Cross-reference regarding related applications This application claims priority to U.S. Provisional Patent Application Serial No. 63/397,395 filed on August 12, 2022. The entire contents of the aforementioned patent application are incorporated herein by reference and become part of this specification. Technology field The present disclosure generally relates to a resource cancellation method and a user equipment (UE). The base station may prioritize scheduling uplink (UL) transmissions. For example, FIG. 1a is a schematic diagram illustrating an example of scheduling transmissions. Referring to FIG. 1a, the gNB schedules a low-priority (LP) UL transmission for UE1 and a high-priority (HP) UL transmission for UE2. It should be noted that in an actual implementation, multiple scheduled transmissions for different UEs may collide. For example, FIG. 1b is a schematic diagram illustrating an example of a transmission collision. Referring to FIG. 1a and FIG. 1b, the gNB schedules resources for an LP UL transmission by DCI (downlink control information) #1 in slot n (n is an integer). However, the gNB may schedule an HP UL transmission using resources for an LP UL transmission by DCI #2 in slot n+1, resulting in a collision between the transmissions of the two UEs. Therefore, to cancel one or some of the UL transmissions, a UL cancellation indication (CI) DCI may be required. The accompanying drawings are incorporated into this specification and constitute part of this specification to provide further understanding of the content of this disclosure.
