Uplink Indication Information for Full-Duplex Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication protocols do not allow terminals to perform uplink transmission simultaneously on the same downlink frequency domain resource used for downlink transmission, lacking a clear method to indicate resources for full-duplexing communication.
Innovation Solution
A method and apparatus for uplink transmission indication, where a network-side device sends uplink indication information to a terminal, indicating an uplink resource for uplink transmission within a downlink resource for downlink transmission, allowing the terminal to determine and utilize this resource for full-duplexing communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal performs uplink transmission on the downlink frequency domain resource for downlink transmission, then the throughput is increased and transmission delay is reduced, but the current protocol does not provide a clear method to indicate such resources
Solution Approach 1:
The patent introduces uplink indication information as an intermediary element carried in downlink control information. This intermediary mechanism allows the network to dynamically indicate uplink resources within downlink resources without requiring fundamental protocol changes, thus enabling full-duplex communication while managing protocol complexity through a modular information structure
Solution Approach 2:
The downlink control information is enhanced to serve multiple functions: it not only controls downlink transmission but also carries uplink indication information to indicate resources for uplink transmission. This multi-functionality allows a single control mechanism to manage both downlink and uplink resources, increasing throughput while avoiding additional separate control procedures
2Loss of time
If full-duplexing mode is implemented, then transmission delay is reduced and uplink coverage is enhanced, but there is no clear indication method for uplink resources in downlink resources
Solution Approach 1:
The network performs preliminary action by pre-configuring and dynamically indicating uplink resources within downlink resources through downlink control information. This allows the terminal to prepare for and execute full-duplex transmission without delay, as the resource allocation is established in advance and communicated clearly to the terminal before transmission occurs
3Productivity
If uplink transmission is performed simultaneously on downlink frequency domain resource, then productivity is improved, but the protocol lacks clear guidance on resource indication
Solution Approach 1:
The patent uses downlink control information as an intermediary carrier to transmit uplink indication information. This ensures that no information is lost during communication, as the network explicitly conveys which resources within the downlink frequency domain should be used for uplink transmission, providing clear guidance to the terminal
Data Source
AI summary
A method, a communication apparatus, and a storage medium for uplink transmission indication and determination. The uplink transmission indication is determined by: sending uplink indication information to a terminal, the uplink indication information being used to indicate to the terminal an uplink resource for uplink transmission among downlink resources for downlink transmission.
