DEVICE AND SYSTEM CHARACTERIZED BY MEASUREMENT, REPORT, AND CHANGE PROCEDURE BY TERMINAL FOR CHANGING TRANSMISSION/RECEPTION POINT, AND BASE STATION PROCEDURE FOR SUPPORTING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18341374 titled 'DEVICE AND SYSTEM CHARACTERIZED BY MEASUREMENT, REPORT, AND CHANGE PROCEDURE BY TERMINAL FOR CHANGING TRANSMISSION/RECEPTION POINT, AND BASE STATION PROCEDURE FOR SUPPORTING SAME

Simplified Explanation

- The patent application describes a communication technique that combines IoT technology and a 5G communication system. - It can be used in various intelligent services such as smart homes, smart buildings, smart cities, connected cars, healthcare, digital education, retail business, and security services. - The technique defines a method for a terminal in a wireless communication system to dynamically change the beam and transmission/reception point based on determination by a base station. - This allows for the efficient transmission and reception of information, reducing power consumption and delay in changing transmission/reception points. - The technique also includes a method for the terminal to select a required reception beam and measure beam information of each transmission/reception point. - This enables rapid and precise determination of beam and transmission/reception point changes, improving overall system performance.

Original Abstract Submitted

The disclosure relates to a communication technique for convergence of an IoT technology and a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The disclosure can be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart cart or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The disclosure defines a mobility method for a terminal residing in a system in which transmission/reception points (TPRs), supporting solely some protocols among entire access stratum protocols comprising PHY, MAC, RLC, PDCP, and RRC, coexist in a wireless communication system. Specifically, the disclosure defines a method for dynamically changing, depending on determination by a base station, a beam and a transmission/reception point to be used for transmitting information to or receiving information from a terminal through a method in which a system using multiple beams notifies, in advance, of a measurement reference signal transmitted using transmission/reception points of different networks, to allow a terminal to select a required reception beam from a corresponding resource and measure beam information of each transmission/reception point, or a terminal transmits measured information as feedback in which each transmission/reception point is specified. Accordingly, the disclosure can provide a criterion of rapid and highly precise determination for changing a beam and a transmission/reception point and thus prevent a terminal from needlessly measuring and reporting, so as to achieve an effect of reduction in the power consumption of the terminal and reduction of delay in change of a transmission/reception point.
