After second modem 203 receives the downlink 5G signal stream of the first SIM card, to the downlink 5G of the first SIM card
Signal stream is demodulated, and the 5G radio signal transmission after demodulation is handled to baseband processing module 201.
It is important to note that being currently in the construction and developing stage of 5G network.For 4G network, 5G
Network has particularity.
According to the requirement of communication protocol, a complete 4G network communication link needs at least two antenna to realize, and one
A complete 5G network communication link needs at least four antenna to realize.In the communication chain that at least four antenna of 5G network is constituted
Lu Zhong, need to maintain antenna realize between electronic equipment and base station SRS (Sounding Reference Signal,
Uplink detection reference signal) communication.That is, needing to maintain in 5G network communication link between electronic equipment and base station
One antenna sends SRS signal to base station, and base station passes through the downlink between the SRS signal assessment base station received and electronic equipment
Channel quality, consequently facilitating the down channel resources between base station and electronic equipment distribute.And according to the requirement of communication protocol,
SRS signal needs switch between at least four antenna of 5G network communication link.That is, electronic equipment passes through 5G network
Each of at least four antenna of communication link antenna successively sends SRS signal to base station in a manner of the time-division.Wherein, SRS
Signal does not carry the Content of Communication communicated between user and other users, is used only for assessment of the base station to down channel quality.
Therefore, in above-mentioned radio circuit 200, SRS signal can switch between four antennas 205.That is,
In the transmit cycle of SRS signal, passes sequentially through an antenna in four antennas 205 and send SRS to base station in a manner of the time-division
Signal, other antennas in four antennas 205 realize the Content of Communication that user is transmitted between electronic equipment and base station.
To, 5G network and 4G network coexisting under two SIM card situations are a problem to be solved in industry,
There is currently no good solutions.
It should be noted that the working method of four antennas 205 is the transmitting week in SRS signal in the embodiment of the present application
