In the case of the second EN-DC scenario:

This hardware circuit can realize LTE dual-antenna switching, NR 1T4R SRS rotation, and NR four-antenna switching in the NSA scenario. At this time, the third switch 831 is switched according to the n41 state; and since LTE only implements dual-antenna switching, the LTE part Only the first network transceiver module 200 and the LTE MHB/NR receiving module 400 work; the signal flow is as follows:

1. When the LTE transmit signal is at the first antenna 701

C. The transmitted signal of NR 1T4R SRS rotation and NR four-antenna switching is shown in Figure 3:

The C11 and NR transmit signals pass through the sixth switch 860, the first combiner 832, the third switch 831, and the first switch 810, and are transmitted at the second antenna 702;
