AI Technical Summary

Technical Problem

The existing power control methods for user terminals in future radio communication systems, which use multiple Radio Access Technologies (RATs), can lead to reduced throughput and coverage due to semi-static configuration of maximum transmission power, causing power shortages at the cell edge.

Method used

A user terminal with a transmitting section, receiving section, and control section that dynamically allocates maximum transmission power across multiple RATs based on configuration information, allowing flexible power management to prevent throughput reduction.

Benefits of technology

This approach prevents reduction in throughput and maintains coverage by enabling flexible power allocation across RATs, ensuring efficient communication even in power-limited situations.

Abstract

A user terminal according to one aspect of the present disclosure includes: a transmitting section that performs transmission by using a plurality of Radio Access Technologies (RATs); a receiving section that receives allocation configuration information including a plurality of pieces of information each related to an allocation of maximum transmission power for each of the plurality of RATs; and a control section that determines an allocation of maximum transmission power of each of the plurality of RATs from a plurality of allocations, based on the allocation configuration information. According to one aspect of the present disclosure, reduction of throughput and so on can be prevented even when a plurality of RATs are used.
