A signal transmission method and apparatus provided by the present disclosure are described in detail below by enumerating several specific embodiments.

Embodiment 1

1 is a flow chart showing the steps of a signal transmission method according to Embodiment 1 of the present disclosure, which may specifically include the following steps:

Step 101: The processor determines whether the power amplifier, the main antenna switch, and the sub-antenna switch are abnormal.

Embodiments of the present disclosure are applicable to a signal transmission device as shown in FIG. The signal transmission device mainly includes: a processor 301, a transceiver 302, a power amplifier 303, a duplexer 304, a main antenna switch 305, a sub antenna switch 306, a main antenna 307, a sub antenna 308, a first bypass 309, and a second The bypass 310, the third bypass 311, the first RF switch 312, the second RF switch 313, and the third RF switch 314. The signal transmission device is applicable to a mobile terminal hardware circuit, wherein the mobile terminal hardware circuit is mainly composed of a baseband processing unit, an audio unit, an RF transmission unit, a main antenna, and a secondary antenna, and the RF transmission unit includes a transceiver, a power amplifier, and a dual Worker, main antenna switch, sub-antenna switch, etc.

The modem in the processor is responsible for modulating and demodulating the signal, and the transceiver is responsible for frequency conversion processing of the modulated and demodulated signal, and the power amplifier is responsible for the converted RF (mobile phone RF) The transmit signal is used for power amplification. The duplexer is responsible for combining the PRX (host receiving signal) and the power amplified TX signal. The main antenna switch is responsible for switching the frequency band of the main antenna, and the sub antenna switch is responsible for switching the frequency band of the sub antenna, DRX (diversity reception). After the signal is converted by the transceiver, it enters the designated frequency band of the sub-antenna directly through the sub-antenna switch.

Compared with FIG. 2, the corresponding signal transmission device of the present disclosure has a bypass with a radio frequency switch connected in parallel between the power amplifier, the main antenna switch and the sub-antenna switch.

The embodiment of the present disclosure mainly performs abnormality determination on the power amplifier, the main antenna switch, and the sub-antenna switch as shown in FIG. 4, and performs emergency processing when abnormal, to ensure basic communication functions of the mobile terminal.

Specifically, the power amplifier, the main antenna switch, and the sub-antenna switch abnormality may be determined according to a certain period. It can be understood that the period can be set according to the actual application scenario, and the embodiment of the present disclosure does not limit it.

In practical applications, it is possible to determine whether the power amplifier, the main antenna switch, and the sub-antenna switch are abnormal by reading configuration information of the power amplifier, the main antenna switch, and the sub-antenna switch. If the reading fails, it is abnormal; if the reading is successful, it is normal.

Step 102: If the power amplifier is abnormal, the processor controls the first RF switch to be closed through an input/output bus, and the transceiver and the duplexer are connected through the first bypass.

In the embodiment of the present disclosure, when the power amplifier is abnormal, the power amplifier is short-circuited through the first bypass, so that the signal processed by the transceiver is directly sent to the duplexer for processing, thereby ensuring basic communication.

Wherein, the first bypass may be a bypass path, and the path is disconnected under default conditions, so that the signal processed by the transceiver is amplified by the power amplifier and then enters the duplexer; when the power amplifier is abnormal, the first A bypass is turned on so that the signal processed by the transceiver directly enters the duplexer through the first path.

It can be understood that since the transceiver has its own amplifying unit, the signal can be initially amplified.

Wherein, the second bypass can be a bypass path. The second RF switch on the path is opened under default conditions to disconnect the second bypass, so that the signal after the duplexer merges passes through the main antenna switch and enters the main antenna; when the main antenna switch is abnormal, the second is closed. The RF switch turns on the second bypass, so that the combined signal of the duplexer directly enters the main antenna through the second bypass.

Step 104: If the secondary antenna switch is abnormal, the processor controls the third RF switch to be closed through an input/output bus, and the transceiver and the secondary antenna are connected through the third bypass.

In the embodiment of the present disclosure, when the secondary antenna switch is abnormal, the secondary antenna switch is short-circuited through the third bypass, so that the output signal of the transceiver directly enters the secondary antenna, thereby ensuring basic communication.

Wherein, the third bypass can be a bypass path. The third RF switch on the path is opened under default conditions to disconnect the third bypass, so that the DRX signal output by the transceiver passes through the secondary antenna switch and enters the secondary antenna; when the secondary antenna switch is abnormal, the third is closed. The RF switch turns on the third bypass, so that the DRX signal output by the transceiver directly enters the secondary antenna through the third bypass.
