AI Technical Summary

⚠Technical Problem

In wireless communication systems, the introduction of dynamic waveform switching does not effectively handle the impact of other scheduling information, resulting in high hardware complexity, high cost, and limited performance improvement.

⚗Method used

By receiving and transmitting information containing the first DCI, the frequency domain resources and physical layer waveforms of the wireless channel can be flexibly indicated using the domain groups and bit groups in the DCI, thereby optimizing frequency domain resource allocation and MCS selection, reducing restrictions on base station-side scheduling, and improving scheduling flexibility and transmission reliability.

🎯Benefits of technology

It achieves flexibility in base station-side scheduling and reliability in control signaling, reduces hardware complexity and cost, improves system performance and spectrum efficiency, reduces the occurrence of inappropriate waveform combinations, and saves control signaling overhead and UE transmission power.

Abstract

The application discloses a method and device used in a node for wireless communication. A first receiver receives first information and a first DCI, the first DCI including a first field; a first transmitter transmits a first bit block on a first wireless channel; wherein the first DCI is used for scheduling the first wireless channel, the first field in the first DCI is used for determining one of frequency domain resources occupied by the first wireless channel or an MCS adopted by the first wireless channel; the first information is used for determining whether a field related to an indication mode of the first field in the first DCI and used for determining a waveform adopted by the first wireless channel exists in the first DCI.
