Software, whether referred to as “software”, “firmware”, “middleware”, “microcode”, or “hardware description language”, or called by other names, should be interpreted broadly, to mean instructions, instruction sets, code, code segments, program codes, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, and the like.

Further, the software, instruction, information, and the like may be transmitted/received via a transmission medium. For example, when software is transmitted from a website, a server, or other remote sources using at least one of wired technology (a coaxial cable, an optical fiber cable, a twisted-pair cable, a digital subscriber line (DSL), and the like) and wireless technology (infrared light, microwaves, and the like), at least one of these wired technology and wireless technology is included in the definition of the transmission medium.

The terms “system” and “network” used in the present disclosure may be used compatibly. The “network” may mean an apparatus (e.g., a base station) included in the network.

In the present disclosure, terms such as “precoding”, “precoder”, “weight (precoding weight)”, “quasi-Co-Location (QCL)”, “transmission configuration indication state (TCI state)”, “spatial relation”, “spatial domain filter”, “transmission power”, “phase rotation”, “antenna port”, “antenna port group”, “l(fā)ayer”, “number of layers”, “rank”, “resource”, “resource set”, “resource group”, “beam”, “beam width”, “beam angle”, “antenna”, “antenna element”, and “panel” can be compatibly used.
