It is two antenna terminals is also single antenna terminal that base station side, which needs distinguishing terminal, first, as shown in Figure 1, specific as follows：
Step S11：Terminal is in the cell attachment access procedure of base station, and meeting reporting ability message is to base station, and the ability
Instruction message is carried in message, which may indicate that terminal sent SRS (Sounding Reference using two days
Signal, detection reference signal) or using single antenna transmission SRS；
Step S12：Base station parses the capabilities message that terminal reports, and determines that the terminal sent SRS using two days, also
It is that SRS is sent using single antenna；When determining that terminal sends SRS using two antennas in the base station, step S13 is performed；And in institute
When stating base station and determining that terminal sends SRS using single antenna, step S14 is performed；
Step S13：Base station is adopted there are two the SRS that antenna port receives terminal and sends, and described two antenna ports can be distinguished
For antenna port 0 and antenna port 1；More specifically, base station can be used antenna port 0 and receive the main SRS that primary antenna is sent, and adopt
The auxiliary SRS of auxiliary antenna transmission is received with antenna port 1；
Step S14：Base station receives the SRS of terminal transmission using an antenna port, and one antenna port can be specific
Antenna port 0.
And when terminal accesses to base station cell, can periodically SRS be sent using two antennas or single antenna；In the present invention
In embodiment, if in the attachment access procedure of above-mentioned terminal, base station determines that the terminal sends SRS using two antennas,
The specific processing procedure in base station is as follows：
Before the concrete processing procedure of base station is introduced, two antenna terminals are first introduced, two antenna terminals include two
Antenna, respectively a primary antenna, an auxiliary antenna；And due to factors such as hardware or environment, auxiliary antenna often breaks down, and leads
Antenna is generally not in failure；And if auxiliary antenna breaks down, can only SRS be sent with primary antenna in two antenna terminals.For
Convenience distinguishes, and the SRS for below sending primary antenna, is referred to as main SRS, and the SRS that auxiliary antenna is sent, referred to as supplemented by
