SEMI-STATIC AND DYNAMIC SUBBAND CONFIGURATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17808184 titled 'SEMI-STATIC AND DYNAMIC SUBBAND CONFIGURATION
Simplified Explanation
The abstract describes a patent application that introduces systems, methods, and devices for supporting subband full duplex configuration in wireless communication.
- The patent application proposes a semi-static configuration for downlink subbands, uplink subbands, and guard bands using RRC signaling.
- The RRC signaling includes information about subband frequency configuration patterns and subband symbol and slot time configuration patterns.
- The patent application also suggests a dynamic configuration for downlink subbands, uplink subbands, and guard bands using RRC signaling in combination with MAC-CE and/or DCI signaling.
- The RRC signaling preconfigures wireless communication devices with multiple subband frequency configuration patterns and subband symbol and slot time configuration patterns.
- The MAC-CE and/or DCI signaling can select and activate specific subband frequency configuration patterns.
- The patent application claims other aspects and features related to this technology.

Original Abstract Submitted
This disclosure provides systems, methods, and devices that support subband full duplex configuration for wireless communication. Semi-static configuration of one or more downlink subbands, one or more uplink subbands, and one or more guard bands may be implemented via RRC signaling configured for subband full duplex communication. The RRC signaling may include subband frequency configuration pattern information and subband symbol and slot time configuration pattern information. Dynamic configuration of one or more downlink subbands, one or more uplink subbands, and one or more guard bands may be implemented by RRC signaling in combination with MAC-CE and/or DCI signaling. The RRC signaling may preconfigure wireless communications devices with a plurality of subband frequency configuration patterns and a plurality of subband symbol and slot time configuration patterns. The MAC-CE and/or DCI signaling may select and/or activate one or more subband frequency configuration patterns. Other aspects and features are also claimed and described.
