AI Technical Summary
Technical Problem
In time-division multiplexing carrier aggregation and dual-connectivity scenarios, the uplink RF chain or uplink transmit antenna of the terminal is limited, resulting in state switching delay and affecting communication reliability and efficiency.
Method used
By determining the uplink transmission mode and restricting the switching of the terminal's transmission mechanism, the consistency of processing between the service node and the terminal is ensured. A reference frame structure and semi-static configuration are adopted to avoid frequent switching.
Benefits of technology
It improves the reliability and efficiency of communication, reduces processing latency, and ensures the stability of uplink transmission.
