Dynamic TRP Selection for Uplink Coordinated Transmission

The patent implements dynamic TRP selection by enabling terminals to measure reference signals from multiple TRPs and report measurements to the network device. The network device then dynamically selects the appropriate TRP transmission direction based on real-time channel conditions, terminal mobility, and environmental factors. This transforms the static TRP configuration into a dynamic system that adapts to changing conditions, resolving the contradiction between configuration simplicity and transmission adaptability.

The patent changes the parameter of TRP configuration from fixed/semi-static to dynamically adjustable. By introducing mechanisms for terminal measurement reporting and network device-based dynamic selection, the TRP transmission direction parameters can be adjusted in real-time based on channel quality, mobility state, and interference conditions. This parameter change enables the system to maintain low complexity while achieving high adaptability through controlled dynamic adjustment.

The patent implements a dynamic TRP selection mechanism where terminals continuously measure reference signals from multiple TRPs and report measurements to the network device. The network device dynamically selects the optimal TRP transmission direction based on real-time conditions. This dynamic approach maintains low signaling overhead by using efficient measurement reporting mechanisms while significantly improving transmission reliability and mobility support through adaptive TRP selection.

The patent introduces a feedback loop where terminals measure reference signals from multiple TRPs and report measurements to the network device. The network device uses this feedback information to dynamically select the appropriate TRP transmission direction. This feedback mechanism enables the system to maintain low signaling overhead while achieving high transmission reliability by making informed TRP selection decisions based on actual channel conditions and terminal mobility state.

The patent transforms the fixed TRP configuration into a dynamic system where the network device selects TRP transmission directions based on real-time measurement reports from terminals. This dynamic selection process maintains relatively simple system architecture while significantly improving service quality through adaptive TRP choice that responds to terminal mobility, channel conditions, and environmental factors.

The patent enables terminals to autonomously measure reference signals from multiple TRPs and generate measurement reports. The network device then uses these reports to automatically select the optimal TRP transmission direction without manual intervention. This self-service mechanism improves service quality and adaptability while keeping system complexity manageable through automated decision-making processes.
