Multi-PDSCH Reception Using QCL Switching for SBFD Symbols

The patent applies dynamics by enabling the UE to dynamically switch between different spatial reception configurations based on the symbol type (SBFD or non-SBFD). The UE determines the current symbol type and selects the appropriate spatial configuration accordingly, making the reception system adaptive rather than fixed. This resolves the contradiction by allowing the UE to match its reception configuration to the BS's varying transmission patterns, thereby maintaining both transmission reliability and reception accuracy.

The patent changes the spatial configuration parameter based on the symbol type. For non-SBFD symbols, the UE uses a first spatial configuration, while for SBFD symbols, it switches to a second spatial configuration. This parameter change allows the UE to align its reception settings with the BS's transmission settings for each symbol type, resolving the mismatch that would otherwise degrade reception accuracy while preserving the benefits of different antenna configurations for transmission reliability.

The patent implements a dynamic spatial configuration selection mechanism where the UE determines the symbol type and selects the appropriate configuration. This dynamic approach improves decoding accuracy by ensuring alignment with BS transmission patterns while maintaining relatively simple implementation through predefined configuration sets. The UE does not need to perform complex real-time calculations but rather selects from pre-configured options based on symbol type identification.

The patent changes the spatial configuration parameter based on detected symbol type. The UE maintains multiple spatial configuration sets in memory and switches between them based on whether the current symbol is SBFD or non-SBFD. This parameter switching mechanism resolves the contradiction by providing adaptive decoding accuracy without requiring complex real-time spatial processing, as the configurations are pre-determined and selected based on simple symbol type detection.

The patent segments the time resources into different symbol types (SBFD and non-SBFD symbols). SBFD symbols enable simultaneous transmission and reception for higher spectral efficiency, while non-SBFD symbols use time-division manner for simpler interference control. The UE is configured to handle both types appropriately, allowing the system to achieve overall improved spectral efficiency while maintaining manageable complexity through clear segmentation of operation modes.

The patent employs periodic alternation between different symbol types in the time domain. The BS transmits using SBFD symbols periodically to achieve simultaneous transmission and reception, interspersed with non-SBFD symbols for simplified interference control. This periodic structure allows the system to achieve improved spectral efficiency on average while keeping interference control complexity manageable through regular pattern repetition, and the UE can efficiently track and adapt to this periodic structure.
