QCL Weighting for Coherent Joint Transmission Demodulation

The patent implements dynamic configuration of QCL parameter weights by allowing the network entity to provide different weight indications for different TCI states. The UE can dynamically adjust the combining weights of QCL parameters (such as Doppler shift, Doppler spread, average delay, delay spread) based on the activated TCI states, enabling adaptive optimization of demodulation and decoding efficiency for coherent joint transmissions across multiple TRPs.

The patent applies parameter changes by introducing weight indications that modify the combining coefficients of QCL parameters from multiple TRPs. The network entity provides weight indications that allow the UE to optimally combine signals from multiple TRPs transmitting on the same time-frequency resource, adjusting parameters such as amplitude weighting to maximize spatial diversity gain while managing processing complexity.

The patent applies partial action by providing weight indications selectively rather than exhaustively. The network entity provides weight indications for TCI states that are activated or relevant for current transmissions, rather than always providing weights for all possible TCI states. This approach maintains QCL parameter combining accuracy for active transmissions while reducing signaling overhead by omitting weights for inactive or non-relevant TCI states.
