Solution Overview

Problem

In multi-slot scheduling for subband non-overlapping full duplex (SBFD), the same frequency domain resource allocation results in inefficient usage of frequency resources, leading to low communication efficiency.

Innovation Solution

A terminal device and network device dynamically allocate different frequency domain resource allocations (FDRAs) for SBFD and non-SBFD communications based on downlink control information (DCI), enabling separate communications on SBFD and non-SBFD slots.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the same frequency domain resource allocation is used for multiple transmissions in multi-slot scheduling, then the device complexity is reduced and ease of operation is improved, but the frequency resource utilization deteriorates and communication efficiency is reduced

Engineering Contradiction:
Improveease of operationVSAvoidcommunication efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent implements dynamic frequency domain resource allocation where the network device can independently adjust FDRAs for different slots based on channel conditions, traffic requirements, and SBFD configuration. This dynamic adjustment mechanism allows the system to adapt resource allocation to changing conditions, improving communication efficiency while maintaining operational simplicity through automated control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the frequency domain resource allocation parameters independently for different slots in multi-slot scheduling. By allowing FDRAs to vary across slots rather than remaining fixed, the system optimizes resource utilization for SBFD communications while maintaining the simplicity of multi-slot scheduling operations.

AI summary

Example embodiments of the present disclosure relate to a terminal device, a network device, methods, apparatuses and a computer readable storage medium for multi-slot scheduling in the context of SBFD. A terminal device receives a DCI from a network device, where the DCI comprises at least one FDRA field for at least one communication to be dynamically scheduled or be activated. The terminal device determines different FDRAs for an SBFD communication and a non-SBFD communication based on the at least one FDRA field in the DCI. As such, the terminal device may perform communications based on the different FDRAs. Thus, the larger bandwidth in the non-SBFD time units can be exploited, the reliability of the multi-slot scheduling can be improved, and the efficiency of the resources may be higher.
