The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
In a first aspect, at least one embodiment of the present disclosure provides an antenna module applied to a terminal device, please refer to fig. 1, which shows a schematic structural diagram of the antenna module, including: at least two antenna paths, wherein the antenna paths comprise an amplifier 101, a first adjusting switch 102 and at least two antennas 103, the amplifier 101 has at least two functional ports, the first adjusting switch 103 is used for connecting the antennas 103 and the amplifier 101, and the corresponding relation between the antennas 103 and the functional ports is periodically adjusted; a radio frequency transceiver 104 having at least two frequency band interfaces; a second adjusting switch 105, configured to connect the antenna path and the radio frequency transceiver 104, and periodically adjust a corresponding relationship between the antenna path and the frequency band interface.
The antenna path is connected to the frequency band interface of the rf transceiver 104, and the amplifier 101 of the antenna path is connected to the frequency band interface, that is, a signal sent by the rf transceiver 104 is amplified by the amplifier 101 and then sent to the antenna 103, and a signal received by the antenna 103 is amplified by the amplifier 101 and then sent to the rf transceiver 104.
Each antenna 103 of each antenna path is disposed at a different position in the terminal device, and the signal states at different positions are different, so that the antennas 103 need to be adjusted and switched according to the priority of the frequency band and the priority of the function. For example, in the antenna position diagram shown in fig. 2, the terminal device has four antennas 201, 203, and 204, and the position of each antenna is different, where the antenna 201 is at the bottom end, the antenna 202 is at the upper middle position on the right side, the antenna 203 is at the top end, and the antenna 204 is at the lower middle position on the left side.
The number of the at least two antennas 103 may be the same as the number of the at least two functional ports, that is, each antenna 103 is connected to one functional port, and the correspondence between the antennas 103 and the functional ports is the one-to-one correspondence between the antennas 103 and the functional ports. The number of the at least two antenna paths may be the same as the number of the at least two frequency band interfaces, that is, each antenna path is connected to one frequency band interface, and the corresponding relationship between the antenna paths and the frequency band interfaces is the one-to-one corresponding relationship between the antenna paths and the frequency band interfaces. Thus, the first adjustment switch 102 can be a multiple pole, multiple throw switch, and the second adjustment switch 105 can also be a multiple pole, multiple throw switch. Furthermore, when the first adjusting switch 102 selects the multiple-pole multiple-throw switch, the selection may be performed according to the number of the antenna 103 and the number of the functional ports, and when the second adjusting switch 104 selects the multiple-pole multiple-throw switch, the selection may be performed according to the number of the antenna paths and the number of the frequency band interfaces. For example, in the example shown in fig. 1, the radio frequency transceiver 104 has two frequency band interfaces in common, namely a first frequency band interface for receiving the fourth generation communication signal (4G) and a second frequency band interface for receiving the fifth generation communication signal (5G), so that two antenna paths are provided and a double-pole double-throw switch is selected as the second adjustment switch 105; in addition, the amplifiers 101 of the two antenna paths can amplify the fourth-generation communication signal and the fifth-generation communication signal, and the amplifiers 101 of the two antenna paths each have two functional ports, that is, a first functional port for transmitting a signal (Transmission/Reception, TRx) and continuously receiving a signal (Primary Reception, PRx) and a second functional port for discontinuously receiving a signal (Discontinuous Reception, DRx), so that the two antenna paths each have two antennas 103 and a double-pole double-throw switch is selected as the first adjustment switch 102.
The antenna module provided by the embodiment of the disclosure can connect the frequency band interface of the rf transceiver 104 with different antenna paths by providing at least two antenna paths connected to different frequency band interfaces of the rf transceiver 104 and the second adjusting switch 105 for adjusting the corresponding relationship between the antenna paths and the frequency band interfaces, thereby adjusting the signal frequency band of the antenna path, and at least two antennas 103 connected to different functional ports of the amplifier 101 and a first adjusting switch 102 for adjusting the correspondence between the antennas 103 and the functional ports are provided in the antenna path, so that the functional ports of the amplifier 101 can be connected to different antennas 103, thereby adjusting the function of the antenna 103, and thus two-layer adjustment can be achieved by the first adjustment switch 102 and the second adjustment switch 105, therefore, the functions and the frequency bands of the antenna 103 can be accurately and efficiently adjusted, and the accuracy and the efficiency of antenna switching are improved. Moreover, the whole antenna module is simple in circuit, large loss is avoided, the structure is zero, and the number of the antennas is increased conveniently.
In a second aspect, at least one embodiment of the present disclosure provides a terminal device, including the antenna module in the first aspect.
The terminal device may be a smart phone, a tablet computer, a desktop/laptop/handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR)/Virtual Reality (VR) device, and the like, and embodiments of the present disclosure are not intended to limit a specific form of the terminal device.
In a third aspect, at least one embodiment of the present disclosure provides an antenna adjusting method applied to the terminal device described in the second aspect, please refer to fig. 3, which illustrates a flow of the method, including steps S301 to S304.
In step S301, at least one of Reference Signal Receiving Power (RSRP) and Signal to Interference plus Noise Ratio (SINR) of the target frequency band is obtained.
The target frequency band may be preset, and the target frequency band is one of the frequency bands supported by the terminal device. For example, in a terminal device supporting a 4G band and a 5G band, the 5G band may be preset as a target band, because currently, both 4G and 5G base stations are co-site resources, most of the 5G band is higher than 4G, and the bandwidth of 5G is about 5 times of 4G, so the coverage distance of the 5G base station is smaller than that of the 4G base station, and the 4G signal is much better than that of 5G, so the reference signal receiving power and the signal-to-noise ratio of the 5G band can more accurately represent the signal and traffic state of the terminal device. It can be understood that, in a terminal device supporting the 4G band and the 5G band, the 4G band may also be used as the target band.
In addition, the reference signal received power may be an average value of the reference signal received power in the first time, and the signal-to-noise ratio may be an average value of the signal-to-noise ratio in the first time, where the first time may be preset, for example, 1 second. By taking the average value in a period of time, the two parameters can be more representative, and the represented result is more accurate.
In step S302, a preferred frequency band is determined according to at least one of the reference signal received power and the signal-to-noise ratio.
The corresponding threshold values can be set for the reference signal received power and the signal-to-noise ratio, the scene where the terminal device is located is judged according to the relation between the reference signal received power and the threshold value and the relation between the signal-to-noise ratio and the threshold value, and a proper frequency band is selected as the priority frequency band according to the scene. The preferred frequency band is a frequency band that needs to satisfy the signal strength requirement first, that is, the antenna with the highest signal strength needs to be used for receiving and transmitting signals in the preferred frequency band.
The reference signal received power can be used for representing the signal strength, and the signal-to-noise ratio can be used for representing the flow rate, so that the two parameters can determine various scenes with different signal strengths and different flow rates. For example, a scene with high signal strength and large flow rate, a scene with light signal and low flow rate, a scene with low signal strength and large flow rate, and a scene with light signal and low flow rate.
In step S303, the correspondence between the antenna and the functional port is adjusted according to a first cycle, and after each adjustment, the correspondence between the antenna and the functional port is corrected by calculating the transmission power and the signal-to-noise ratio (Tx _ cal _ PWR) according to the protocol of the priority band.
In this step, the corresponding relationship between the antenna and the functional port is adjusted once every first period, timing can be performed by the timer, and whether the first period is reached is determined according to a timing result of the timer. When the corresponding relationship between the antennas and the functional ports is adjusted, that is, the original one-to-one corresponding relationship between at least two antennas and at least two functional ports is changed, and a new one-to-one corresponding relationship is generated. Optionally, all the corresponding relationships between the at least two antennas and the at least two functional ports may be counted in advance, sorted, and adjusted in sequence according to the sorting result, that is, when each corresponding relationship is adjusted, the corresponding relationship is adjusted to be the next corresponding relationship. For example, the amplifier of the antenna path has two functional ports, that is, a first functional port for transmitting and continuously receiving signals and a second functional port for intermittently receiving signals, the antenna path is provided with two antennas, and when the double-pole double-throw switch is selected as the first adjustment switch, the correspondence relationship is adjusted in this step, that is, the antenna connected to the first functional port is switched to be connected to the second functional port, and the antenna connected to the second functional port is switched to be connected to the first functional port.
When the correspondence between the antenna and the functional port is corrected, the adjusted correspondence may be maintained, the correspondence before adjustment may be returned, or the correspondence may be corrected to a correspondence that is different from the correspondence before adjustment and the correspondence after adjustment.
In addition, the first period of each antenna path may be the same or different. The timing start for each antenna path may be the same or different.
In addition, the protocol calculated transmit power may be an average of the protocol calculated transmit power over a first time, where the first time may be preset, for example, 1 second. By taking the average value in a period of time, the parameters can be more representative, and the represented result is more accurate.
In one example, the correspondence of the antenna to the functional port may be corrected in the following manner: responding to the fact that the difference value of the protocol calculation transmitting power of the priority frequency band before adjustment is larger than the difference value of the protocol calculation transmitting power of the priority frequency band after adjustment and the signal-to-noise ratio of the priority frequency band after adjustment is larger than the difference value of the signal-to-noise ratio of the priority frequency band before adjustment and is larger than or equal to a fourth threshold value, and keeping the corresponding relation after adjustment; otherwise, switching to the corresponding relation before adjustment.
The third threshold may be preset, for example, set to 5dB, and the fourth threshold may also be preset, for example, set to 3 dB.
In step S304, the corresponding relationship between the antenna path and the frequency band interface is adjusted according to the second period, and after each adjustment, the corresponding relationship between the antenna path and the frequency band interface is corrected by calculating the transmission power and the signal-to-noise ratio according to the protocol of the preferred frequency band.
In this step, the corresponding relationship between the antenna path and the frequency band interface is adjusted once every second period, timing can be performed by the timer, and whether the second period is reached is determined according to a timing result of the timer. When the corresponding relationship between the antenna paths and the frequency band interfaces is adjusted, that is, the original one-to-one corresponding relationship between at least two antenna paths and at least two frequency band interfaces is changed, and a new one-to-one corresponding relationship is generated. Optionally, all the corresponding relations between the at least two antenna paths and the at least two frequency band interfaces may be counted in advance, sorted, and adjusted in sequence according to the sorting result, that is, when adjusting each corresponding relation, the corresponding relation is adjusted to be the next corresponding relation. For example, the radio frequency transceiver has two frequency band interfaces in common, that is, a first frequency band interface for transceiving a fourth-generation communication signal and a second frequency band interface for transceiving a fifth-generation communication signal, the antenna module is provided with two antenna paths, and when the double-pole double-throw switch is selected as the second adjusting switch, the corresponding relationship is adjusted in this step, that is, the connection between the first frequency band interface and the two antenna paths is switched, that is, the antenna path connected to the first frequency band interface is switched to be connected to the second frequency band interface, and meanwhile, the antenna path connected to the second frequency band interface is switched to be connected to the first frequency band interface.
When the correspondence between the antenna path and the frequency band interface is corrected, the adjusted correspondence may be maintained, the correspondence before adjustment may be returned, or the correspondence may be corrected to a correspondence that is different from the correspondence before adjustment and the correspondence after adjustment.
In addition, the protocol calculated transmit power may be an average of the protocol calculated transmit power over a first time, where the first time may be preset, for example, 1 second. By taking the average value in a period of time, the parameters can be more representative, and the characterized result is more accurate.
In one example, the correspondence between the antenna paths and the frequency band interfaces may be corrected as follows: responding to the fact that the difference value of the protocol calculation transmitting power of the priority frequency band before adjustment is larger than the protocol calculation transmitting power of the priority frequency band after adjustment is larger than or equal to a fifth threshold value, the difference value of the signal-to-noise ratio of the priority frequency band after adjustment is larger than the signal-to-noise ratio of the priority frequency band before adjustment is larger than or equal to a sixth threshold value, and keeping the corresponding relation after adjustment; otherwise, switching to the corresponding relation before adjustment.
The fifth threshold may be preset, and may be the same as the third threshold, or may be different from the third threshold; the sixth threshold may be preset, and may be the same as or different from the fourth threshold.
In the embodiment of the disclosure, a scene and a corresponding priority frequency band are determined according to two parameters, namely, a reference signal receiving power and a signal-to-noise ratio, of a target frequency band, a corresponding relation between an antenna and a function port is further adjusted at regular time according to a first period, and after adjustment, a protocol of the priority frequency band is used for calculating a transmitting power to correct the corresponding relation between the antenna and the function port, so that reasonable configuration of the antenna in an antenna passage is completed. By timing adjustment and correction, the reasonable configuration of the antenna is realized, and the switching efficiency and accuracy of the antenna are improved.
In some embodiments of the present disclosure, the terminal device supports 4G and 5G, and may determine the priority frequency band according to the following manner: determining a fifth generation communication signal as a priority frequency band in response to the reference signal received power being greater than or equal to a first threshold; in response to the reference signal received power being less than the first threshold and the signal-to-noise ratio being greater than or equal to a second threshold, determining a fourth generation communication signal as a priority band; and determining a fifth generation communication signal as a priority frequency band in response to the reference signal received power being less than the first threshold and the signal-to-noise ratio being less than a second threshold.
The reference signal receiving power is greater than or equal to a first threshold value, and is characterized by a scene with high signal strength, the reference signal receiving power is smaller than the first threshold value, the signal-to-noise ratio is greater than or equal to a second threshold value, and is characterized by a scene with low signal strength and small flow, the reference signal receiving power is smaller than the first threshold value, and the signal-to-noise ratio is smaller than the second threshold value, and is characterized by a scene with low signal strength and large flow. Since a scene with high signal strength and a scene with low signal strength and large traffic are both scenes with 5G priority, the 5G band is used as a priority band, and a scene with low signal strength and small traffic is a scene with 4G priority, the 4G band is used as a priority band.
