Description

Fast wake-up and data transmission method with reduced capability control and encoding for wireless communications, and apparatus, system and non-transitory computer readable storage device employing the same Cross Reference to Related Applications The application claims the benefit of U.S. provisional patent application No. 63/543,377 filed 10 at 2023, 10, the entire contents of which are incorporated herein by reference. Technical Field The present invention relates generally to communication systems, apparatuses, methods and non-transitory computer readable storage devices, and more particularly to a fast wake-up and data transmission method with reduced capability control and encoding for wireless communication, and wireless communication apparatuses, systems and non-transitory computer readable storage devices employing the fast wake-up and data transmission method. Background Wireless communication systems such as mobile communication systems are well known. In wireless communication systems, power consumption is often an important concern, especially for User Equipment (UE). Energy conservation will become a basic design requirement for 6G. UE power saving and network power saving have been discussed in the fifth generation (fifth generation, 5G) new air interface (NR) standard. In particular, there are different power consumption modes with different power consumption levels, e.g. deep sleep, light sleep, micro sleep. In the sixth generation (6G), energy conservation will continue to be a key feature. However, due to the wider variety of device and application types, the higher network density, the efficient energy-efficient design will be more challenging than previous standards. Control information such as downlink control information (downlink control information, DCI) is transmitted on a physical downlink control channel (physical downlink control channel, PDCCH), which is important for scheduling both downlink and uplink data. On the other hand, channel coding is an important part of the physical layer that provides error correction capability. How much capability a channel code can provide depends largely on its coding parameters or configuration.
