Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing and coordinating full duplex and half duplex transmissions, particularly in terms of resource allocation and interference mitigation, which can lead to ambiguity and increased signaling overhead.
Innovation Solution
A method and apparatus for wireless communication that involve receiving and transmitting configuration messages for periodic communications, including indications of periodicity, to activate and manage both full duplex and half duplex resources using a single DCI message, thereby reducing ambiguity and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate DCI messages are used to activate full duplex and half duplex periodic communication configurations, then the activation can be performed separately for each duplex mode, but the signaling overhead increases and coordination complexity increases
Solution Approach 1:
The patent combines multiple periodic communication configurations (full duplex and half duplex) into a single DCI message for activation. The DCI message includes a first periodic communication configuration for full duplex periodic communications and a second periodic communication configuration for half duplex periodic communications, both activated simultaneously through one message, thereby reducing signaling overhead while maintaining proper coordination.
Solution Approach 2:
The DCI message is designed to serve multiple functions by containing configuration parameters for both full duplex and half duplex periodic communications. This universal message structure allows the system to activate different duplex modes through a single standardized signaling mechanism, reducing the need for multiple specialized messages.
2Adaptability or versatility
If separate DCI messages are used to activate full duplex and half duplex periodic communication configurations, then each configuration can be managed independently, but the device complexity and processing overhead increase
Solution Approach 1:
The patent merges the activation of full duplex and half duplex periodic communication configurations into a single DCI message processing operation. The UE receives one DCI message containing both configuration sets and processes them together, reducing the number of separate processing operations required while maintaining the ability to independently configure each duplex mode.
3Measurement precision
If ambiguity in periodicity application between full duplex and half duplex resources is reduced through detailed configuration messages, then resource allocation precision improves, but the message size and signaling overhead increase
Solution Approach 1:
The patent applies local quality by including duplex mode identification indicators within the periodic communication configuration. Each configuration set (full duplex and half duplex) contains specific indicators that precisely define the duplex mode and periodicity application, allowing the UE to accurately interpret resource allocation without requiring oversized messages. The configuration is tailored to the specific duplex mode requirements.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a configuration for periodic communications, wherein the configuration indicates a periodicity for the periodic communications. The wireless communication device may receive an indication of whether the periodicity applies to at least one of full duplex resources or half duplex resources. The wireless communication device may communicate based at least in part on the configuration for periodic communications, the periodicity, and the indication. Numerous other aspects are described.
