AI Technical Summary

Technical Problem

In asymmetric downlink single-transmitter-receiver and uplink multiple-transmitter-receiver systems, how user equipment can effectively send uplink signals to uplink receiving equipment is an urgent problem to be solved.

Method used

The user equipment receives and uses the first parameters, including offset value, offset index, target received power, nominal power, power compensation parameters, power deviation between Msg3 PUSCH signal and preamble, power deviation between MsgA PUSCH signal and preamble, maximum transmit power, power backoff value, power level and transmit module information, to transmit signals to the uplink receiving device.

Benefits of technology

By acquiring signal transmission parameters, user equipment can accurately send signals to the uplink receiving device, reducing the transmission load on the first device, reducing signal interference, and improving system performance.
