SRS Configuration for Antenna Switching and Frequency Hopping

The patent segments the SRS transmission configuration into multiple independent parameters: frequency hopping pattern, repetition factor, antenna switching configuration, and symbol allocation. Each parameter can be independently configured and optimized, allowing flexible combination to achieve enhanced capacity without overwhelming complexity. The segmentation enables the system to divide the SRS transmission into manageable components that can be controlled separately.

The patent introduces dynamic configuration capabilities where the base station can adaptively adjust SRS transmission parameters based on real-time channel conditions. The repetition factor, frequency hopping pattern, and antenna switching can be dynamically modified to optimize performance. This dynamic approach allows the system to respond to varying network conditions and maximize SRS capacity while managing complexity through adaptive rather than fixed configurations.

The patent implements periodic repetition of SRS transmissions where the same SRS sequence is transmitted multiple times at different time instances. This periodic action enhances channel estimation accuracy by providing multiple samples for processing. The repetition factor can be configured to balance between estimation accuracy and time consumption, allowing the system to use only the necessary number of repetitions to achieve adequate accuracy without excessive time loss.

The patent employs preliminary frequency hopping configuration where the frequency hopping pattern is pre-defined and configured before actual SRS transmission. This allows the system to prepare the frequency sequence in advance, reducing the time needed during actual transmission. The preliminary configuration of hopping patterns enables efficient use of frequency resources while maintaining accurate channel estimation across different frequency bands.

The patent segments the antenna ports into different groups and assigns them to different time slots or frequency resources. This segmentation allows multiple antenna ports to be used for enhanced coverage while managing resource allocation complexity through systematic distribution. Each antenna port or group of ports is allocated specific resources, making the complexity manageable through structured assignment rather than uncontrolled multi-antenna operation.

The patent introduces time and frequency dimensions as additional allocation parameters beyond just antenna ports. Instead of only managing spatial resources, the system leverages temporal and spectral dimensions to distribute antenna port usage. This multi-dimensional approach enhances coverage by activating multiple antenna ports across different time instances and frequency bands, while the additional dimensions provide structured frameworks for managing the increased complexity.
