AI Technical Summary
LTE/5G wireless repeaters introduce uplink bottom noise interference, and existing technologies cannot reasonably control uplink information transmission, resulting in reduced base station receiver sensitivity and communication terminal failure.
By receiving base station system information, extracting the time slot occupied by the random access channel, detecting whether the current time slot is occupied by the random access channel, and sending uplink information to the base station if the detection result is yes, the transmission of uplink information is controlled by combining the correlation of the orthogonal frequency division multiplexing (OFDM) symbols and a predetermined threshold.
Accurately determining whether the current time slot is a random access time slot avoids missed or false judgments, ensures normal communication of communication terminals, and reduces uplink information noise interference.
