AI Technical Summary

Technical Problem

Current communication systems, such as 3GPP 5G NR, face challenges in efficiently configuring resources for subband full duplex (SBFD) operation, particularly in managing flexible radio resources and avoiding conflicts between downlink and uplink transmissions.

Method used

The proposed method involves configuring subband full duplex slot configurations that include dedicated uplink radio resources surrounded by flexible radio resources. This configuration allows for flexible scheduling and prioritization of uplink transmissions, ensuring efficient use of radio resources.

Benefits of technology

This approach enables improved resource allocation and utilization in SBFD operation, enhancing communication efficiency by allowing simultaneous downlink and uplink transmissions on different subbands while minimizing conflicts.

Abstract

Embodiments of the present disclosure provide a method and an apparatus for configuring resources for subband full duplex, SBFD, operation. A method (400) performed by a terminal device, comprising: receiving (S402), from a network node, a subband full duplex, SBFD, slot configuration; and communicating (S404), with the network node, based at least on the SBFD slot configuration. The slot configuration indicates a plurality of radio resources of a slot; and the plurality of radio resources include: at least one downlink, DL, radio resource used for DL transmission; and at least one flexible radio resource used for flexible scheduling. According to embodiments of the present disclosure, the exemplary embodiments of the present disclosure propose a mechanism to specifically configure / allocate resources for subband full duplex, SBFD, operation.
