The details will be described respectively below.

This embodiment will be described from the perspective of an antenna switching device. The device may be integrated into an electronic device, and the electronic device may be an electronic device with a network function such as a mobile interconnection network device (such as a smart phone or a tablet computer).

First, referring to FIG. 1, FIG. 1 is a schematic flowchart of an antenna switching method provided in an embodiment of the present application, including the following steps:

Step S101, during the process of establishing a communication connection between the electronic device and the base station, use the first antenna to send connection information to the base station with the initial power as the transmission power.

In the embodiment of the present application, the electronic device is an electronic device that includes at least two antennas, such as an electronic device that can be designed for dual antennas. In other embodiments, the electronic device can also be an electronic device that includes three or four antennas or even more Electronic equipment, which is not further limited here.

In the LTE network, the random access process refers to the process from when the user sends a random access preamble and tries to access the network to the establishment of a basic signaling connection with the network. Random access is very critical in the mobile communication system. The step is also the last step in establishing a communication link between the terminal and the base station.

In the process of establishing a communication connection between an electronic device and a base station, random access is a necessary process for establishing a wireless link between the UE and the network. Only after the random access is completed, the eNB (evolved Node B, evolved base station) and the UE data interoperability between them. Among them, the UE can realize two basic functions through random access: 1. Obtain uplink synchronization (TA) with the eNB. Once the uplink loses synchronization, the UE can only transmit data in the PRACH. 2. Apply for upstream resources.

According to different ways of triggering services, random access can be divided into contention-based random access and non-contention-based random access. Please refer to the embodiment by taking the contention random access as an example. As shown in FIG. 2, the contention random access includes four steps, namely Random Access Preamble (MSG1) and Random Access Response (MSG2), Scheduled Transmission (MSG3) and Contention Resolution (MSG4).

In this embodiment of the application, the electronic device uses the first antenna to send connection information to the base station with the initial power as the transmission power, wherein the above connection information may be a random access preamble (MSG1), and the above initial power may be the initial power specified by the base station. power.

Step S102, if the first antenna does not receive the response information returned by the base station within a preset time period, increase the transmit power of the first antenna.

In this embodiment of the present application, the response information returned by the foregoing base station may be a random access response. Specifically, if the eNB detects the random access preamble code, it will report it to the MAC, and subsequently feed back the random access response of the MAC in the downlink shared channel PDSCH within the random access response window.

In an embodiment, one MSG2 may contain Preambles of multiple UEs, that is, respond to random access requests of multiple UEs. The UE identifies whether it has received the random access response from the eNB by detecting whether the MSG2 carries the Preamble code it sent.

If the electronic device does not receive the response information returned by the base station, that is, MSG2 within a preset time period, it increases the transmit power of the first antenna and performs retransmission. Wherein, the above-mentioned increase of the transmit power of the first antenna may include various methods, such as multiple increments according to a fixed increment, or skip increments, or directly increase to the maximum power specified by the base station, and so on.

For example, if the initial transmission power of the first antenna is 15dBm, and the maximum transmission power specified by the base station is 40dBm, if the connection information is sent to the base station with the initial power and the response information returned by the base station is not received within the preset time, you can gradually The transmit power of the first antenna is increased until it reaches 40dBm, and it can also be directly increased to 40dBm at one time. It should be noted that every time after increasing the transmit power of the first antenna, it is necessary to judge whether the response information returned by the base station is received within the preset time period. If not, continue to increase the transmit power of the first antenna until the maximum power.

Step S103, if the transmit power of the first antenna is increased to a first preset value, and the response information returned by the base station is not received yet, the standing wave ratios of the first antenna and the second antenna are acquired respectively.

In the embodiment of the present application, the above-mentioned first preset value may be the maximum power specified by the base station. When the transmission power of the first antenna increases to the maximum power, it is judged whether the electronic device has received the response information returned by the base station. to obtain the standing wave ratios of the first antenna and the second antenna respectively. Among them, standing wave ratio is called voltage standing wave ratio, also known as VSWR (Voltage Standing Wave Ratio). Refers to the ratio of the standing wave antinode voltage to the valley voltage amplitude, also known as standing wave coefficient and standing wave ratio. When the standing wave ratio is equal to 1, it means that the impedance of the feeder and the antenna are completely matched. At this time, all high-frequency energy is radiated by the antenna, and there is no energy reflection loss; when the standing wave ratio is infinite, it means total reflection, and the energy is not radiated at all. Therefore, the larger the VSWR, the worse the performance of the antenna.

In one embodiment, the VSWR of the antenna can be calculated through a bidirectional coupler, as shown in FIG. 3 , which is a schematic diagram of a radio frequency circuit provided in an embodiment of the present application. In this embodiment, the electronic device has two antenna designs. And support antenna switching, respectively the first antenna 201 and the second antenna 202, through the double pole double throw switch 203, the main set and diversity of the electronic equipment can be switched between the first antenna 201 and the second antenna 202, the radio frequency front end includes The bidirectional coupler 204 and the radio frequency transceiver 205, the bidirectional coupler 204 can calculate the VSWR of the first antenna 201 and the second antenna 202, so as to determine the downlink signal strength of the two antennas.

Step S104, judging whether the standing wave ratio of the second antenna is smaller than the standing wave ratio of the first antenna, if yes, execute step S105, otherwise continue to send connection information.

In the embodiment of the present application, since the antenna standing wave ratio represents the index of the matching degree between the antenna feeder line and the base station (transceiver), the standing wave ratio is generated because the incident wave energy is not completely absorbed (radiated) when it is transmitted to the input end of the antenna. , Generate reflected waves, superimposed and formed. So the larger the VSWR, the larger the reflection and the worse the match. If the standing wave ratio of the second antenna is smaller than the standing wave ratio of the first antenna, that is, the downlink signal strength of the second antenna is stronger, step S105 is further performed. If the standing wave ratio of the second antenna is not less than the standing wave ratio of the first antenna, it is determined that the signal of the second antenna is worse, and the first antenna may continue to be used to send the connection information.

Step S105, using the second antenna to send connection information to the base station with the initial power as the transmission power.

In other embodiments, if the electronic device is an electronic device with more than two antennas, when the second antenna also does not receive the response information, it can continue to compare the standing wave ratio of the third antenna and switch to the third antenna to send to the base station connection information. Wherein, the retransmission rule of the second antenna may be the same as that of the first antenna, that is, the transmit power of the second antenna is also increased according to the power increase specified by the base station, which will not be further described here.

It should be noted that, in the embodiment of the present application, if the process of increasing the transmission power of the first antenna and sending the connection information to the base station, or the process of sending the connection information to the base station with the first preset value as the transmission power In the process, after receiving the response information returned by the base station, a communication connection is established with the base station according to the response information.

In the embodiment of the present application, the above-mentioned electronic device can be any device capable of LTE communication, such as: mobile phone, tablet computer (Tablet Personal Computer), laptop computer (Laptop Computer), personal digital assistant (personal digital assistant, PDA for short) ), Mobile Internet Device (MID) or wearable device (Wearable Device), etc.

As can be seen from the above, the embodiments provided by this application can use the first antenna to send connection information to the base station with the initial power as the transmission power during the process of establishing a communication connection between the electronic device and the base station. If the response information returned by the base station is received, the transmit power of the first antenna is increased. If the transmit power of the first antenna is increased to the first preset value and the response information returned by the base station has not been received, the second The standing wave ratio of the first antenna and the second antenna is judged whether the standing wave ratio of the second antenna is smaller than the standing wave ratio of the first antenna, and if so, the second antenna is used as the initial power as the transmission power to send the connection information to the base station. In this application, when the first antenna does not get a response to the LTE random access, it switches to an antenna with a stronger signal and tries again, thereby improving the success rate of the LTE random access of the electronic device.

According to the description of the previous embodiment, the antenna switching method of the present application will be further described below.

Please refer to FIG. 4. FIG. 4 is a schematic flowchart of another antenna switching method provided in the embodiment of the present application, including the following steps:

Step S201, during the process of establishing a communication connection between the electronic device and the base station, use the first antenna to send connection information to the base station with the initial power as the transmission power.

In this embodiment, the LTE network random access process refers to the process from when the user sends a random access preamble and tries to access the network to the establishment of a basic signaling connection with the network. Random access is divided into contention-based random access and non-contention-based random access. Please refer to the embodiment by taking the contention random access as an example. The contention random access includes four steps, namely Random Access Preamble (MSG1) and Random Access Response (MSG2), Scheduled Transmission (MSG3) and Contention Resolution (MSG4).

The electronic device uses the first antenna to send connection information to the base station with initial power as transmission power, where the above connection information is a random access preamble (MSG1), and the above initial power may be the initial power specified by the base station.

Step S202, if the response information returned by the base station is not received within the preset time period, the transmit power of the first antenna is increased by using the second preset value as an increment until it reaches the first preset value.

If the electronic device does not receive the response information returned by the base station, that is, MSG2, it increases the transmit power of the first antenna with the second preset value as an increment until it reaches the first preset value. For example, the initial transmission power of the first antenna is 15dBm, and the maximum transmission power specified by the base station is 40dBm. If the response information returned by the base station is not received after sending the connection information to the base station with the initial power, you can gradually increase the first antenna with a fixed increment of 5dBm. When the transmit power of the antenna is increased to 20dBm, if the response information returned by the base station is still not received, continue to increase to 25dBm, and so on until the transmit power is increased to 40dBm.

In other embodiments, the transmit power of the first antenna can also be gradually increased with a non-fixed increment, such as increasing the transmit power of the first antenna by 18dBm, and if the response information returned by the base station has not been received, continue to increase to 24dBm, etc. and so on until the transmit power is increased to 40dBm. After increasing the transmit power of the first antenna each time, it is necessary to judge whether the response information returned by the base station is received, and if not, continue to increase the transmit power of the first antenna up to the maximum power.

Step S203, if the transmit power of the first antenna is increased to the first preset value, and the response information returned by the base station has not been received, acquire the first antenna to use the first preset value as the transmit power to send a connection to the base station information times.

In the embodiment of the present application, the above-mentioned first preset value may be the maximum power specified by the base station. When the transmission power of the first antenna increases to the maximum power, it is judged whether the electronic device has received the response information returned by the base station. , the retransmission is always performed at the maximum power value, and the number of times the first antenna sends connection information to the base station with the first preset value as the transmit power is counted.

Step S204, judging whether the number of times reaches the preset number of times, if yes, execute step S205, otherwise, continue sending.

If the number of retransmissions of the first antenna does not reach the preset number of times, the maximum power is always used for retransmission, and after each retransmission, it is necessary to determine whether the response information returned by the base station is received, and if not, continue to retransmit. If the number of retransmissions of the first antenna reaches the preset number and the response information returned by the base station is still not received, it can be determined that the current transmitting antenna of the electronic device may be in a harsh antenna environment such as being blocked. If the communication with the base station cannot be obtained, go to step S205.

Step S205, obtaining standing wave ratios of the first antenna and the second antenna respectively.

In this embodiment, the standing wave ratio refers to the ratio of the standing wave antinode voltage to the valley voltage amplitude, and is also called standing wave coefficient or standing wave ratio. When the standing wave ratio is equal to 1, it means that the impedance of the feeder and the antenna are completely matched. At this time, all high-frequency energy is radiated by the antenna, and there is no energy reflection loss; when the standing wave ratio is infinite, it means total reflection, and the energy is not radiated at all. Therefore, the larger the VSWR, the worse the performance of the antenna.

Step S206, judging whether the standing wave ratio of the second antenna is smaller than the standing wave ratio of the first antenna, if yes, execute step S207, otherwise continue to send connection information.

Step S207, using the second antenna to send connection information to the base station with the initial power as the transmit power.

If the standing wave ratio of the second antenna is smaller than that of the first antenna, that is, the downlink signal strength of the second antenna is stronger, switch to the second antenna and use the initial power as the transmission power to send connection information to the base station. If the standing wave ratio of the second antenna is not less than the standing wave ratio of the first antenna, it is determined that the signal of the second antenna is worse, and the first antenna may continue to be used to send the connection information.

In the embodiment of the present application, through antenna switching, when one antenna performs LTE random access and does not get a response, the downlink signal strength of the two antennas is judged, and the antenna with strong signal is switched to retry. Through the double-antenna retry method based on downlink reception quality judgment, the success rate of LTE random access is improved. Compared with simply retrying by switching antennas, this embodiment adds a judgment based on uplink transmission quality before switching, so as to avoid useless retrying by switching to an antenna with a worse antenna environment. And directly use the uplink indicator to judge the quality of the antenna, which will be more accurate in the selection of the antenna.

It should be noted that, in the embodiment of this application, after each time the connection information is sent to the base station using the first antenna or the second antenna, it is necessary to determine whether the response information returned by the base station is received. If the response information returned by the base station is received , establish a communication connection with the base station according to the response information.

Specifically, the eNB will blindly detect the preamble in the PRACH. If the eNB detects the random access preamble Radom Access Preamble, it will report it to the MAC, and then within the random access response window, the MAC will be fed back in the downlink shared channel PDSCH. The random access response Radom Access Response.

Among them, the RA Response (MSG2) message includes: RA Preamble in MSG1 (for UE matching operation), UE uplink timing advance TA (11 bits, coarse adjustment), backoff fallback parameter (the re-initiation of the Preamble code should delay the reconnection input time), PUSCH uplink scheduling information UL_Grant allocated for MSG3 transmission (including frequency hopping, modulation and coding rate, access resource and access time, etc.), Temple C-RNTI (for MSG3 scrambling).

RA response (MSG2) is an independent MAC PDU carried in DL-SCH. One MSG2 can contain the Preamble of multiple UEs, that is, respond to the random access requests of multiple UEs. The UE identifies whether it has received the random access response from the eNB by detecting whether the MSG2 carries the Preamble code it sent.

In an embodiment, the above step of establishing a communication connection with the base station according to the response information may specifically include:

Sending a wireless connection request to the base station according to the response information;

The connection permission information returned by the base station is received, and a communication connection is established according to the connection permission information, wherein the connection permission information includes a connection identifier.

In an embodiment, the UE sends MSG3 to the eNB, and the UE can obtain uplink synchronization according to the TA adjustment amount in the RA Response, and transmit MSG3 in the uplink resource allocated by the eNB for subsequent data transmission.

The initial transmission of MSG3 is the only uplink data dynamic scheduling transmission indicated by the MSG2 message of the MAC layer. After the random access process is completed, other dynamic scheduling uplink initial transmissions are all indicated through DCI0 for resource allocation. The MSG3 message starts to support the HARQ process, and the retransmission resource and location are notified to the UE through the DCI0 scrambled by the Temple C-RNTI.

The eNB sends MSG4 to the UE, and the eNB and the UE finally complete the contention resolution through MSG4. The above connection permission information can be the identification of the contention resolution, and finally the electronic device establishes a communication connection with the base station.

It can be seen from the above that in the embodiment of the present application, during the process of establishing a communication connection between the electronic device and the base station, the first antenna can be used to send connection information to the base station with the initial power as the transmission power. Two preset values are used as an increment to increase the transmit power of the first antenna until it reaches the first preset value. When the response information is received, the number of times the first antenna sends connection information to the base station with the first preset value as the transmission power is obtained, and it is judged whether the number of times reaches the preset number. Antenna and the standing wave ratio of the second antenna, judge whether the standing wave ratio of the second antenna is less than the standing wave ratio of the first antenna, if not less than, continue to retransmit, if less than, use the initial power of the second antenna as the transmission power to The base station sends connection information. In this application, when the first antenna does not get a response to the LTE random access, it switches to an antenna with a stronger signal and tries again, thereby improving the success rate of the LTE random access of the electronic device.
