(beamforming) and beam management techniques are used a system that increases connection continuity in cellular communication systems It is related to the system. The invention specifically relates to base 10 with integrated sensing and communication (ISAC) capabilities. Detection of environmental changes and moving objects through the stations, possible Predicting beam obstructions in advance and preventing obstructions before they occur first, connection interruptions and packet losses caused by beam interceptions and improving communication continuity and service quality by reducing delays It is related to the system that provides it. 15 State of the Art In mobile communication systems, especially those requiring high data speeds and broadband millimeter wave (mmWave) and millimeter wave are used to provide their widths. The use of high-frequency bands on the wave is becoming increasingly important. This In high-frequency bands, the propagation characteristics of communication signals are 20. Due to this, road losses are increasing and signals are being disrupted by environmental objects, human bodies, vehicles, It can be more easily weakened by structural elements and similar obstacles. This Therefore, sufficient coverage in high-frequency mobile communication systems and Directional antenna structures and beamforming are used to ensure connection quality. 25 from beamforming and beam management techniques It is being used. Especially for multiple input multiple output (MIMO) and very large-scale multiple input multiple output. In radio access networks supporting Massive MIMO (M-MIMO), by the base station Communication with user equipment via a multi-directional beam generated. This can be achieved. Beamforming techniques allow radio frequency energy to be applied at specific rates. the concentration of the signal in a spatial direction, and thus the signal obtained at the receiver side. 2 The aim is to improve its quality. However, in high frequency bands The physically narrow nature of the beams used, the user become more sensitive to movements and changes occurring in the environment This is what causes it to come. Current technology in mobile communication systems involves beam selection, beam alignment, and 5. Beam switching operations generally involve channel status information, received signal strength, and signal... quality, feedback provided by reference signal measurements and / or user equipment This is carried out based on notifications. The movement of user equipment, channel conditions change or the signal quality of the current beam falls below a certain level If it falls below 10, another suitable beam should be selected or the current beam should be reduced to 10. Realignment can be performed. However, communication, especially in mmWave and higher frequency bands, Changes in the channel do not always occur gradually. Humans, a vehicle or other environmental object between the base station and user equipment As a result of entering the line of sight, the existing communication route was disrupted in a short time. 15 This can be blocked, resulting in a sudden drop in the received signal level. This is possible. This situation exists especially in narrow-beam communication systems. the effectiveness of the beam decreases significantly or completely in a short period of time. This can cause it to get lost. A significant portion of current beam management approaches in technology focus on channel 20. measurements taken after changes or blockages have occurred It operates on a reactive working principle.

After detecting a deterioration in signal quality, an alternative solution was found. beam exploration, selection, or realignment processes This process involves beam scanning, beam measurement, beam selection, and 25 Alignment processes may require additional time and resources; especially for fast processes. Maintaining the existing connection in situations of mobility or sudden disruption. It can become difficult. Beam loss or sudden drop in connection quality occurring in existing systems; packet losses, retransmissions, increased latency, decreased data rate, and some 30 In these situations, it can lead to a temporary interruption of the communication link. The effects are on next-generation mobile devices requiring low latency and high reliability. This is becoming more prominent in communication applications. 3 On the other hand, integrated sensing and communication With the development of Communication, ISAC (Instrument for Combination and Air Conditioning) technologies, base stations have become more than just... not for communication purposes, but to observe the position, movement, and similar characteristics of objects in the environment. Techniques for using these techniques to perceive spatial / temporal characteristics. This has emerged. However, in current beam management solutions, detection 5 the link between environmental information obtained as a result and beam management decisions Solutions for integrated use in a way that increases its continuity are limited. It can remain. Furthermore, in a significant portion of current approaches, communication relies on a single active beam. It is based on the principle of maintaining a connection with the user. In this case, the active beam is 10 If it becomes unusable due to an unforeseen disruption, an alternative beam will be used. Until the transition process is complete, the connection quality may be significantly reduced or This can cause the connection to be interrupted. Multiple beams of light to the same user. or to support connection continuity in relation to the same communication link Even if evaluated in this way, the environmental perception of these beams is 15 The technical need for preventive and dynamic management using this information continues. is doing. Application number WO2024124390A1 involves the detection of a base station using RF sensing. or detecting any obstructions that may occur in more beams and Depending on the obstacle's position relative to the user, the beam used for communication will be 20 It is related to the system that enables its selection. However, the application includes integrated sensing and environmental communication (ISAC) capabilities through base stations Detection of changes and moving objects, possible beamforming with M-MIMO. anticipating their failure and preventing them from happening before the failure occurs connection interruptions, packet losses, and 25 caused by beam interference. The continuity of communication is not being ensured by reducing delays. In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion...
