Include:
Step 201, when the first communication chip and the second communication chip receive and dispatch signal of communication simultaneously, control the first communication core
Piece and the second communication chip pass through the signal of communication that common antenna receives and dispatches the first communication chip by coupler connection common antenna
With the signal of communication of the second communication chip.
Wireless terminal can be determined that the communications status of the first communication chip and the second communication chip, if the first communication chip
It is in busy state with the second communication chip, then can be determined that the first communication chip and the second communication chip while transmitting-receiving is logical
Believe signal.
Optionally, wireless terminal can use arbitration unit to the communications status of the first communication chip and the second communication chip
It is arbitrated, wherein arbitration unit generally can be the controller of wireless terminal, or the first communication chip is second logical
Believe the pure hardware such as chip, is also possible to the application program stored in controller and memory, the first communication chip and first
The software and hardwares such as the application program stored in application program, the second communication chip and the second communication chip stored in communication chip
Combination.
Wireless terminal is arbitrated using communications status of the arbitration unit to the first communication chip and the second communication chip
When, may include the following two kinds situation:
In the case of the first, when arbitration unit is the communication chip for being used for transmission signal of communication, connect using arbitration unit
