AI Technical Summary

⚠Technical Problem

Existing wireless communication systems, such as 5G NR, lack sufficient consideration for communications using different unit areas, which can hinder improvements in communication quality and throughput.

⚗Method used

A terminal and wireless communication method that utilize a receiving unit to receive a physical downlink control channel order and control unit to perform communication using quasi co-location assumptions based on synchronization signal blocks and resources for a random access response, enabling communication in a cell-free system with dynamic area formation by multiple antennas/TRPs.

🎯Benefits of technology

Enables appropriate communication in a cell-free system, improving communication quality and throughput by reducing interference and enhancing energy efficiency, especially in high-frequency environments.

Abstract

A terminal according to one aspect of the present disclosure comprises: a reception unit that receives a physical downlink control channel (PDCCH) order which includes identification information indicating one or more synchronization signal blocks among a plurality of synchronization signal blocks and which triggers a random access procedure; and a control unit that uses one or more quasi co-location (QCL) assumptions, which are based on the PDCCH order, the one or more synchronization signal blocks, and / or a resource for a random access response (RAR) PDCCH, in order to receive the RAR PDCCH.
