Description

TECHNICAL FIELD Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to operation in light of cancellation (e.g., full or partial dropping or cancelling) of transmissions via a link established between devices of a wireless communication system. Certain embodiments of the technology discussed below can enable and provide techniques for dependent procedure operation impacted by uplink cancellation. INTRODUCTION Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and the like. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Such networks, which are usually multiple access networks, support communications for multiple users by sharing the available network resources. A wireless communication network may include a number of base stations or node Bs that can support communication for a number of user equipments (UEs). A UE may communicate with a base station via downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station. A base station may transmit data and control information on the downlink to a UE and/or may receive data and control information on the uplink from the UE. On the downlink, a transmission from the base station may encounter interference due to transmissions from neighbor base stations or from other wireless radio frequency (RF) transmitters. On the uplink, a transmission from the UE may encounter interference from uplink transmissions of other UEs communicating with the neighbor base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and uplink. Interference and other factors may result in instances of various transmissions being cancelled, disturbed, dropped, etc. or otherwise negatively impacted. For example, one or more uplink transmissions from a UE to a base station may be fully or partially dropped or cancelled. Cancellation, droppage, or disturbance of transmissions can cause user dissatisfaction, impact subsequent operation of the communication device, degrade communication performance, affect system operation and throughput, etc. Asia Pacific Telecom: "Considerations on UL inter-UE prioritization and multiplexing", 3GGP draft, R1-1912254, discusses UL CI monitoring, reference UL resource, and the aspect of handling PUCH on cancelled PUSCH. KR 2019 0098708 A relates to transmitting of uplink data according to uplink cancellation indication information in a next-generation wireless network.

SUMMARY The invention is defined by the appended independent claims. Advantageous embodiments are subject of the dependent claims. The following summarizes some aspects of the present disclosure to provide a basic understanding of the discussed technology. This summary is not an extensive overview of all contemplated features of the disclosure and is intended neither to identify key or critical elements of all aspects of the disclosure nor to delineate the scope of any or all aspects of the disclosure. Its sole purpose is to present some concepts of one or more aspects of the disclosure in summary form as a prelude to the more detailed description that is presented later. In one aspect of the disclosure, within the scope of the claims, a method of wireless communication is provided. The method may comprises cancelling a first uplink transmission. Cancelling the first uplink transmission is a fast cancellation if the first uplink transmission is cancelled with insufficient time for a device transmitting the first uplink transmission to meet a first one or more timelines of a plurality of timelines. Cancelling the first uplink transmission is a slow cancellation if the first uplink transmission is cancelled with sufficient time for the device transmitting the first uplink transmission to meet a second one or more timelines of a plurality of timelines. The method comprises providing a transmission indication attribute corresponding to the cancelling the first uplink transmission for operation of a dependent procedure, wherein the dependent procedure is a procedure that is impacted by the cancelling of the first uplink transmission. The transmission indication attribute indicates to the dependent procedure that the first uplink transmission is considered as transmitted or is considered as not transmitted in correspondence with the cancelling the first uplink transmission being the fast cancellation or the slow cancellation.
