Description

CROSS-REFERENCE TO RELATED APPLICATION This patent application claims priority to U.S. Provisional Patent Application No. 63/717,432, filed on Nov. 7, 2024, entitled “UPLINK CONTROL CHANNEL REPETITIONS FOR FULL-DUPLEX SYSTEM,” and assigned to the assignee hereof. The disclosure of prior Provisional Patent Application 63/717,432 is considered part of and is incorporated by reference into this patent application in its entirety. FIELD OF THE DISCLOSURE Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with uplink control channel repetitions for a full-duplex system. INTRODUCTION Wireless communication systems are widely deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, and/or other traffic. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication among multiple wireless communication devices including user devices or other devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, and/or device transmit power, among other examples). Such multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable different wireless communication devices to communicate on a local, municipal, national, regional, or global level. An example telecommunication standard is New Radio (NR). NR, which may also be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP). NR (and other RATs beyond NR) may be designed to better support enhanced mobile broadband (eMBB) access, Internet of things (IoT) networks or reduced capability device deployments, and ultra-reliable low latency communication (URLLC) applications. To support these verticals, NR systems may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple-input multiple-output (MIMO), licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelink and other device-to-device direct communication technologies (for example, cellular vehicle-to-everything (CV2X) communication), multiple-subscriber implementations, high-precision positioning, and/or radio frequency (RF) sensing, among other examples. As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases.
