1Reliability
If direct communication between terminals in a unicast scheme is implemented, then reliability and latency requirements for vehicle communication services are met, but system complexity increases
Solution Approach 1:
The base station acts as an intermediary to manage and coordinate direct terminal-to-terminal communication. It configures resources, monitors communication quality, and handles control signaling, thereby enabling reliable unicast communication without requiring terminals to independently manage complex communication protocols.
Solution Approach 2:
The system implements feedback mechanisms where terminals report communication status and quality metrics to the base station. This feedback enables the base station to dynamically adjust resource allocation and communication parameters to maintain high reliability while managing system complexity.
2Productivity
If advanced technologies such as beamforming, massive MIMO, and advanced coding modulation schemes are utilized, then communication performance is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent divides the communication system into distinct functional modules: beamforming units for spatial processing, MIMO units for multi-antenna operations, and coding modulation units for data processing. Each module handles specific tasks independently, making the implementation of advanced technologies more manageable and less complex.
Solution Approach 2:
The base station is designed with multi-functional capabilities that can perform beamforming, massive MIMO processing, and advanced coding modulation. This universal design allows a single base station to handle multiple advanced communication technologies simultaneously, improving efficiency without proportionally increasing complexity.

AI summary
The disclosure relates to a 5th generation (5G) or a pre-5G communication system provided to support a higher data transfer rate than a system after a 4th generation (4G) communication system such as long term evolution (LTE). An operation method of a terminal in a wireless communication system includes: obtaining an RLC transmission mode and RLC configuration information in the process of determining a V2X service requiring configuration of a unicast session and configuring the unicast session with another terminal; if the terminal is determined to be in the coverage of a base station, receiving an RLC transmission mode and RLC configuration information from the base station; and if it is determined that the terminal is not located in a base station coverage, obtaining a pre-configured unicast session and pre-configured RLC configuration information for each RLC transmission mode, which is mapped to a V2X service.
