The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
In a first aspect, at least one embodiment of the present disclosure provides an antenna module, which is 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 including an amplifier 101, a first adjusting switch 102, and at least two antennas 103, wherein 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 periodically adjusting the correspondence between the antennas 103 and the functional ports; a radio frequency transceiver 104 having at least two frequency band interfaces; and the second adjusting switch 105 is used for connecting the antenna path with the radio frequency transceiver 104 and periodically adjusting the corresponding relation between the antenna path and the frequency band interface.
The antenna path is connected with the frequency band interface of the radio frequency transceiver 104, that is, the amplifier 101 of the antenna path is connected with the frequency band interface, that is, the signal sent by the radio frequency transceiver 104 is amplified by the amplifier 101 and then sent to the antenna 103, and the signal received by the antenna 103 is amplified by the amplifier 101 and then sent to the radio frequency transceiver 104.
Wherein each antenna 103 of each antenna path is disposed at a different location in the terminal device, and signal states of the different locations 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 in total, each of which is different in position, in which the antenna 201 is located at the bottom, the antenna 202 is located at the right middle, the antenna 203 is located at the top, and the antenna 204 is located at the left middle.
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 with one functional port, and the corresponding relationship between the antennas 103 and the functional ports is a one-to-one corresponding relationship 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 with one frequency band interface, and the corresponding relationship between the antenna paths and the frequency band interfaces is a one-to-one corresponding relationship between the antenna paths and the frequency band interfaces. Thus, the first regulating switch 102 may select a multiple pole, multiple throw switch, and the second regulating switch 105 may also select a multiple pole, multiple throw switch. Further, when the first regulating switch 102 selects the multiple pole multiple throw switch, the selection may be performed according to the number of the antenna 103 and the functional ports, and when the second regulating switch 104 selects the multiple pole multiple throw switch, the selection may be performed according to the number of the antenna paths and the frequency band interfaces. For example, in the example shown in fig. 1, the radio frequency transceiver 104 has two frequency band interfaces in total, 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 adjusting switch 105; in addition, the amplifiers 101 of the two antenna paths are each capable of signal amplification for 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, i.e., 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 intermittently receiving a signal (Discontinuous Reception, DRx), so that the two antennas 103 are each provided for the two antenna paths, and a double pole double throw switch is selected as the first regulating switch 102.
According to the antenna module provided by the embodiment of the disclosure, by setting at least two antenna paths connected with different frequency band interfaces of the radio frequency transceiver 104 and the second regulating switch 105 for regulating the corresponding relation between the antenna paths and the frequency band interfaces, the frequency band interfaces of the radio frequency transceiver 104 can be connected with different antenna paths so as to regulate the signal frequency band of the antenna paths, and at least two antennas 103 connected with different functional ports of the amplifier 101 and the first regulating switch 102 for regulating the corresponding relation between the antennas 103 and the functional ports are arranged in the antenna paths, so that the functional ports of the amplifier 101 can be connected with different antennas 103 so as to regulate the functions of the antennas 103, therefore, two-layer regulation can be realized through the first regulating switch 102 and the second regulating switch 105, and both the functions and the frequency bands of the antennas 103 can be regulated accurately and efficiently, thus the accuracy and the efficiency of antenna switching are improved. Moreover, the whole antenna module circuit is simple, avoids larger loss, has a zero structure, and is convenient for increasing the number of antennas.
In a second aspect, at least one embodiment of the present disclosure provides a terminal device, including an antenna module set according to the first aspect.
Wherein 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 (personal digital assistant, PDA), an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, etc., and embodiments of the present disclosure are not intended to limit the specific form of the terminal device.
In a third aspect, at least one embodiment of the present disclosure provides an antenna adjustment method applied to the terminal device 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 received power (Reference Signal Receiving Power, RSRP) and signal-to-noise ratio (Signal to Interference plus Noise Ratio, SINR) of the target frequency band is acquired.
The target frequency band can be preset, and the target frequency band is one of frequency bands supported by the terminal equipment. For example, in the terminal device supporting the 4G frequency band and the 5G frequency band, the 5G frequency band may be preset as the target frequency band, because at present, the 4G base station and the 5G base station are both co-sited resources, the frequency band of the 5G is mostly higher than the 4G, and the bandwidth of the 5G is about 5 times that of the 4G, so the coverage distance of the 5G base station is smaller than that of the 4G base station, the 4G signal is far better than that of the 5G base station, and therefore, the reference signal receiving power and the signal-to-noise ratio of the 5G frequency band can more accurately represent the signal and the traffic state of the terminal device. It will be appreciated that in terminal devices 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 an average over a period of time, the two parameters can be made more representative, and the result characterized is more accurate.
In step S302, a priority 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 receiving power and the signal to noise ratio respectively, the scene where the terminal equipment is located is judged according to the relation between the reference signal receiving 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 a priority frequency band according to the scene. The preferred frequency band refers to a frequency band that is required to satisfy signal strength requirements first, that is, an antenna with highest signal strength is required to be used for signal transmission and reception 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 size, so that the two parameters can determine various scenes with different signal strengths and different flow sizes. For example, a scene with high signal strength and large traffic, a scene with light high signal and low traffic, a scene with low signal strength and large traffic, a scene with light low signal and low traffic.
In step S303, the correspondence between the antenna and the functional port is adjusted according to a first period, and after each adjustment, the correspondence between the antenna and the functional port is corrected according to the transmission power and the signal-to-noise ratio (tx_cal_pwr) calculated according to the protocol of the priority band.
In this step, the corresponding relation between the antenna and the functional port is adjusted once every first period, and the timer is used to count time, and whether the first period is reached is determined according to the count result of the timer. When the corresponding relation between the antennas and the functional ports is regulated, namely, the original one-to-one corresponding relation between at least two antennas and at least two functional ports is changed, and a new one-to-one corresponding relation is generated. Alternatively, all the corresponding relations between at least two antennas and at least two functional ports may be counted in advance, and sorted, and sequentially adjusted according to the sorting result, that is, when each corresponding relation is adjusted, the next corresponding relation is adjusted. For example, the amplifier of the antenna path has two functional ports, i.e., a first functional port for transmitting a signal and continuously receiving a signal and a second functional port for intermittently receiving a signal, and when the antenna path is provided with two antennas and a double pole double throw switch is selected as the first adjusting switch, the correspondence is adjusted in this step, i.e., switching is performed between the two connection relations of the first functional port and the second functional port with the two antennas, that is, switching the antenna connected with the first functional port to be connected with the second functional port, and simultaneously switching the antenna connected with the second functional port to be connected with the first functional port.
When the corresponding relation between the antenna and the functional port is corrected, the corresponding relation after adjustment can be maintained, the corresponding relation before adjustment can be returned, and the corresponding relation can be corrected to be different from the corresponding relation before adjustment and the corresponding relation after adjustment.
In addition, the first period of each antenna path may be the same or different. The starting point of timing for each antenna path may be the same or different.
In addition, the protocol calculation transmission power may be an average value of the protocol calculation transmission power in a first time, where the first time may be set in advance, for example, 1 second. By taking an average over a period of time, the parameters can be made more representative and the results characterized are more accurate.
In one example, the correspondence of the antenna to the functional port may be corrected as follows: responding to the fact that 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 by a difference value which is larger than or equal to a third threshold value, and 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 by a difference value which 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, to 5dB, and the fourth threshold may be preset, for example, to 3dB.
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 according to the transmission power and the signal-to-noise ratio calculated according to the protocol of the priority frequency band.
In this step, the corresponding relation between the antenna path and the frequency band interface is adjusted once every second period, and the timer is used to count time, and whether the second period is reached is determined according to the count result of the timer. When the corresponding relation between the antenna paths and the frequency band interfaces is regulated, namely, the original one-to-one corresponding relation between at least two antenna paths and at least two frequency band interfaces is changed, and a new one-to-one corresponding relation is generated. Alternatively, all the corresponding relations between at least two antenna paths and at least two frequency band interfaces may be counted in advance, and sorted, and sequentially adjusted according to the sorting result, that is, when each corresponding relation is adjusted, the next corresponding relation is adjusted. For example, the radio frequency transceiver has two frequency band interfaces, namely, a first frequency band interface for receiving and transmitting a fourth generation communication signal and a second frequency band interface for receiving and transmitting a fifth generation communication signal, and when the antenna module is provided with two antenna paths and the double pole double throw switch is selected as the second adjusting switch, the corresponding relationship is adjusted in this step, that is, the two connection relationships between the first frequency band interface and the second frequency band interface and the two antenna paths are switched, that is, the antenna path connected with the first frequency band interface is switched to be connected with the second frequency band interface, and the antenna path connected with the second frequency band interface is switched to be connected with the first frequency band interface.
When the corresponding relation between the antenna path and the frequency band interface is corrected, the corresponding relation after adjustment can be maintained, the corresponding relation before adjustment can be returned, and the corresponding relation can be corrected to be different from the corresponding relation before adjustment and the corresponding relation after adjustment.
In addition, the protocol calculation transmission power may be an average value of the protocol calculation transmission power in a first time, where the first time may be set in advance, for example, 1 second. By taking an average over a period of time, the parameters can be made more representative and the results characterized are more accurate.
In one example, the correspondence of antenna paths to frequency band interfaces may be corrected as follows: responding to the fact that the protocol calculation transmitting power of the priority frequency band before adjustment is larger than or equal to a fifth threshold value, and the difference value of the signal to noise ratio of the priority frequency band after 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 or 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 through two parameters of reference signal receiving power and signal to noise ratio of a target frequency band, the corresponding relation between an antenna and a functional port is further regulated at regular time according to a first period, and the corresponding relation between the antenna and the functional port is corrected by calculating transmitting power by using a protocol of the priority frequency band after regulation, so that reasonable configuration of the antenna in an antenna passage is completed, the corresponding relation between the antenna passage and a frequency band interface is regulated at regular time according to the first period, and the corresponding relation between the antenna passage and the frequency band interface is corrected by calculating transmitting power by using a protocol of the priority frequency band after regulation, so that reasonable configuration of the antenna among the antenna passages is completed. Through timing adjustment and correction, reasonable configuration of the antenna is realized, and 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 in the following manner: determining that the fifth-generation communication signal is a priority frequency band in response to the received power of the reference signal being greater than or equal to a first threshold; determining that the fourth-generation communication signal is a priority frequency band in response to the reference signal received power being smaller than the first threshold and the signal-to-noise ratio being greater than or equal to a second threshold; and determining that the fifth-generation communication signal is a priority frequency band in response to the reference signal received power being smaller than the first threshold and the signal-to-noise ratio being smaller than a second threshold.
The method comprises the steps that a reference signal receiving power is larger than or equal to a first threshold value, a scene with high signal strength is represented, the reference signal receiving power is smaller than the first threshold value, the signal to noise ratio is larger than or equal to a second threshold value, the signal strength is represented by a scene with low signal strength and low 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, the signal strength is represented by a scene with low signal strength and high flow. Since both the scene with high signal strength and the scene with low signal strength and large flow rate are 5G-priority scenes, the 5G frequency band is used as a priority frequency band, and the scene with low signal strength and small flow rate is used as a 4G-priority scene, and the 4G frequency band is used as a priority frequency band.
In addition, the first threshold and the second threshold may be set in advance, for example, the first threshold may be set to-105 dBm and the second threshold may be set to 3dB.
