Common Configuration Signaling for Full-Duplex Slot Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems face challenges in coordinating full-duplex and half-duplex operations between base stations and user equipment, leading to increased signaling and collision likelihood due to varying device capabilities.
Innovation Solution
Implementing configuration common signaling techniques, where base stations transmit different slot format patterns or a single full-duplex slot format to groups of user equipment based on their capabilities, and dynamically adjust groupings using control signaling to coordinate full-duplex communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base stations transmit different slot format patterns to different groups of user equipment based on full-duplex or half-duplex capabilities, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments user equipment into different groups based on their full-duplex or half-duplex capabilities. Base stations transmit different slot format patterns to different groups, allowing optimized communication for each capability type while managing complexity through structured grouping and configuration.
2Reliability
If base stations dynamically adjust groupings using control signaling, then coordination of full-duplex operations is improved, but signaling overhead increases
Solution Approach 1:
The patent implements dynamic grouping adjustments where base stations can reconfigure which user equipment belongs to full-duplex or half-duplex groups based on current channel conditions and traffic requirements. This dynamic reconfiguration improves coordination reliability while the structured control signaling mechanism manages overhead through efficient update protocols.

AI summary
Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit first control signaling to a first set of user equipments (UEs) which identifies a first common configuration information element indicating a first slot format pattern for use by the first set of UEs. The base station may also transmit second control signaling to a second set of UEs which identifies a second common configuration information element indicating a second slot format pattern for the second set of UEs. The first information element and the second information element may be the same or different based on full-duplexing or half-duplexing capabilities of the UEs. In some other cases, the base station may identify a grouping configuration for assigning respective UEs to first or second UE groups which are either associated with uplink or downlink communications with the full-duplex base station.
