Carry out the transmission of uplink information.
In one implementation, in the case where the transmission configuration state of LTE SRS is to open, 5G terminal is removing last
5G SRS is transmitted in other symbols except a symbol, and does not transmit 5G SRS in the frequency domain occupied by LTE PUSCH, that is, is done
Silence processing so not only can reduce the interference between 5G SRS transmission and LTE SRS transmission, also can reduce 5G SRS biography
The defeated interference between LTE PUSCH transmission.With it is upper similarly, symbol mentioned herein may include SC-FDMA symbol or
OFDM symbol.
Above-mentioned steps 204 can earlier than or be later than step 202 execute, can also be performed simultaneously with step 202.
In the present embodiment, 5G terminal can transmission configuration status information and LTE PUSCH based on LTE SRS scheduling
Information carries out the transmission of uplink information, so as to further decrease the transmission and the transmission of LTE uplink information of 5G uplink information
Between interference.
