Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and more particularly, to an antenna tuning method, an antenna tuning device, an electronic device, and a storage medium. Background Art

[0002] With the development of communication technologies, terminals that include antennas for transmitting and receiving radio waves to perform signal transmission are widely used. A terminal generally needs to tune the antenna to a suitable state to ensure good antenna transmit (TX) efficiency and receive (RX) efficiency. Generally, the terminal tunes the antenna by modifying the tuning parameters (tune code) of a tuner to optimize the antenna efficiency. However, an antenna tuned based on the tuning parameters preset at the factory (i.e., default tuning parameters) often cannot meet the requirements for antenna efficiency in various different scenarios. For example, when the terminal is in a state such as being held in the hand, due to changes in parameters such as impedance, the antenna based on the default tuning parameters cannot ensure optimal radio frequency performance. To improve the antenna efficiency, the tuning parameters of the antenna tuner are usually changed by changing the transmit performance of the terminal antenna. However, the method of adjusting the antenna by changing the transmit performance usually sacrifices a certain amount of transmit performance to meet the requirements for the receive performance of the antenna, but this method cannot meet the different performance requirements of the antenna for different services in different network environments.

[0003] Therefore, there is a need for an antenna tuning method, an antenna tuning device, an electronic device, and a storage medium that can dynamically tune the antenna to an optimal state considering the performance requirements of different services for the antenna. Summary of the Invention

Another example, "performing at least one of Step 1 and Step 2" means the following three parallel situations: (1) performing Step 1; (2) performing Step 2; (3) performing both Step 1 and Step 2.

[0032] In addition, terms such as "first", "second", etc. in the claims, the description, and the drawings of the present disclosure are only used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present disclosure described here can be implemented in an order other than the order shown or described here. In addition, the same reference numerals represent the same or similar elements. The embodiments described in the following examples do not represent all the embodiments consistent with the present disclosure. On the contrary, they are only examples of the embodiments consistent with some aspects of the present disclosure.

[0033] To facilitate the understanding of the concept of the present disclosure, before the present disclosure is described in detail, some terms of the present disclosure are first explained.

[0034] In the present disclosure, a "terminal" may be a device that uses an antenna to send and receive signals, and it may also be referred to as a User Equipment (UE), a terminal device, a Mobile Station (MS), a Mobile Terminal (MT), a Subscriber Station (SS), a remote terminal, a wireless terminal, a receiving point, etc. The terminal according to the present disclosure may be a device with wireless communication functions. For example, but not limited to, examples of the terminal may include, but are not limited to, at least one of a smart phone, a tablet personal computer (PC), a mobile phone, a video phone, an e-book reader, a desktop PC, a laptop computer, a netbook computer, a workstation, a server, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), an MP3 player, a mobile medical device, a camera, a wearable device, a vehicle-mounted device, etc.

[0035] In addition, in the present disclosure, a "network device" may be any device that provides wireless access to a network for a terminal, and it may also be referred to as a network node, a base station (BS), a core network node, or a network server, etc. Examples of network devices according to the present disclosure may include, but are not limited to, a transmit point (TP), a transmit-receive point (TRP), an enhanced (or "evolved") base station (eNodeB or eNB), a 5G base station (gNB), a macro cell, a femto cell, wireless fidelity (WiFi), an access point (AP), or other devices with wireless capabilities.

[0036] In the present disclosure, antenna performance may also be understood as "antenna efficiency". Here, the "radiation power" and "received power" of the antenna are used to describe the antenna efficiency or antenna performance. The greater the radiation power and received power, the higher the antenna efficiency or the better the antenna performance. In this document, the maximum radiation power may be denoted as TxBe, and the maximum received power may be denoted as RxBe. In the following, reference will be made to Figure 1 and Figure 2 to describe in detail the definition of "radiation power".

[0037] Figure 1 is a diagram showing each power calculation point in the antenna structure according to an embodiment of the present disclosure. Figure 2 is a diagram showing the relationship between the transmit power and the radiation power of the antenna.

[0038] Referring to Figure 1 , the antenna structure may include a wireless transceiver (WTR), a power amplifier (PA), and a tuner. The wireless transceiver is used to transmit or receive signals at different frequencies. The power amplifier is used to amplify the signals. According to an embodiment of the present disclosure, the transmit signal amplified by the power amplifier can be used to calculate or determine the transmit power of the antenna, that is, the transmit power can be calculated at the output of the power amplifier in Figure 2 . In this document, "transmit power" may also be referred to as "radio frequency power" or "radio frequency transmit power", where the maximum transmit power may be the maximum transmit power determined by the radio frequency link of the terminal.

[0039] According to an embodiment of the present disclosure, due to line losses such as adapters and feeders connecting the antenna, the radiation power used to describe the antenna efficiency is often less than the transmit power. Referring to Figure 2The transmitted power (Pin) determined at a front-end circuit (such as a power amplifier) becomes the radiation power (Pout) of the antenna when transmitted through the antenna. Here, the radiation power of the antenna is the difference between the transmitted power of the antenna and the reflected power (Prev), that is, Pout = Pin – Prev.

[0040] According to an embodiment of the present disclosure, the antenna efficiency conversion rate η is determined by using the transmitted power and the reflected power of the antenna. Specifically, the antenna efficiency conversion rate η is determined by using the following equation (1).

[0041] η = (Pin - Prev) / Pin (1)

[0042] Wherein, the Pin of the antenna is a pre-known or determined value, and Prev is a value determined based on experience or measured dynamically in real time. The application of the antenna efficiency conversion rate η will be described in detail in the embodiments below.

[0043] Although Figure 1 shows an antenna structure according to an embodiment of the present disclosure, this antenna structure is only for illustrating the differences of each power calculation point, and the antenna of the present disclosure is not limited thereto.

[0044] To avoid obscuring the present disclosure with unnecessary details, the specific processing of receiving and transmitting signals of the antenna structure is not described in detail herein.

[0045] Returning to Figure 2 According to an embodiment of the present disclosure, different tuning parameters (tune code) correspond to different impedances and / or resonant frequencies of the tuner. By using the tuning parameters, the impedance and / or resonant frequency of the tuner can be adjusted to change the state of the tuner, so as to achieve the purpose of improving the antenna performance.

[0046] As described above, in order to adjust the antenna performance, the tuner of the antenna is adjusted by using the tuning parameters to improve the antenna efficiency. The antenna efficiency is closely related to the frequency of the wireless signal, and different frequencies require different tuning parameters. For the frequency division duplex (FDD) mode, since the transmit frequency and the receive frequency are different, a terminal with the same physical antenna for transmitting and receiving cannot tune the transmit performance and the receive performance of the antenna to the optimal at the same time.

[0047] To balance the transmission efficiency and reception efficiency of the antenna, a fixed allowable tolerance (or simply referred to as "headroom") for adjusting the radiation power corresponding to the transmission efficiency can be preset. The allowable tolerance of the radiation power can represent the difference between the maximum radiation power TxBe and the allowable minimum radiation power. In other words, the radiation power within the range defined by the allowable tolerance of the maximum radiation power TxBe meets the antenna transmission performance requirements. Within the range of the radiation power determined based on the allowable tolerance, the optimal reception power is determined, and the tuning parameter corresponding to the determined optimal reception power is determined as the tuning parameter for tuning the antenna. The following refers to Figure 3 for a detailed description of an example of determining the tuning parameter based on a fixed tolerance.

[0048] Figure 3 is a diagram showing the process of determining the tuning parameter based on a fixed tolerance. In Figure 3 , taking the Long-Term Evolution (LTE) Band B14 as an example, the radiation power and reception power corresponding to different tuning parameters are shown, assuming that the preset fixed tolerance is 1 dB. Figure 3 In the chart in, the vertical axis represents the radiation power (in dB) and the horizontal axis represents the tuning parameter (tune code).

[0049] Referring to Figure 3 , it can be seen that when the tuning parameter is approximately 12, the antenna has the maximum radiation power TxBe, and at this time the antenna transmission performance is optimal. However, the reception power when the tuning parameter is 12 differs from the maximum reception power (RxBe) among all the reception powers of the antenna (in Figure 3 , the tuning parameter corresponding to RxBe is 70) by more than 2 dB. In this case, the optimal reception power can be searched within the range defined by the radiation power within the range of the fixed tolerance loss of the radiation power (i.e., 1 dB). As can be seen from Figure 3 , within the range defined by the radiation power within the 1 dB tolerance range relative to TxBe, the corresponding maximum received RF power is at the tuning parameter of 41. Therefore, the tuning parameter for the tuner for adjusting the antenna is determined as 41.

[0050] In this case, the terminal will lose a certain amount of transmission performance or transmission efficiency (for example, a performance loss of less than or equal to 1 dB of the radiation power) to meet the requirements of the reception performance or reception efficiency, but the determined tuning parameter may not be the optimal tuning scheme for the antenna, and the transmission performance and reception performance corresponding to the determined tuning parameter may not achieve an optimal balanced state.

[0051] In addition, due to various unpredictable changes in the environment where the terminal is located, the preset fixed tolerance cannot be adjusted appropriately according to various environments. In this case, the dynamic adjustment of the antenna performance cannot be achieved either.

[0052] For example, due to the complex and ever-changing network environment, the requirements for transmission performance or reception performance of different services of a terminal are not the same in different network environments. For example, for a transmission-sensitive (type) service (such as a random access process, data upload processing, etc.), the direct cause of the terminal dropping the line may be the degradation of the transmission performance adjusted by a fixed tolerance. For example, for a reception-sensitive (type) service (such as online video playback, data download, etc.), the reference signal receiving power (RSRP) or signal-to-noise ratio (SNR) of the received signal may be too poor due to the non-optimal reception performance, resulting in problems such as the terminal being unable to demodulate and data jamming. Therefore, when the transmission performance is limited, adjusting the tuning parameters by a fixed tolerance cannot well meet the performance requirements of different services of the terminal in different network environments.

[0053] Considering at least the above problems, an antenna tuning method, an antenna tuning device, an electronic device, and a storage medium for dynamically determining tuning parameters are proposed. According to an embodiment of the present disclosure, the tolerance condition can be dynamically adjusted based on the service type and network parameters (especially the uplink path loss (ULPL)) of the terminal to determine appropriate tuning parameters. According to an embodiment of the present disclosure, the block error rate (BLER) can also be combined to determine appropriate tuning parameters within a suitable tolerance range to tune the antenna to the optimal efficiency. The following will refer to Figures 4 to 7 Describe an antenna tuning method, an antenna tuning device, an electronic device, and a storage medium according to an embodiment of the present disclosure.

[0054] Figure 4 Is a flowchart showing an antenna tuning method according to an embodiment of the present disclosure.

[0055] Refer to Figure 4 , in step S410, in response to detecting an abnormal transmission state of the antenna, determine the maximum radiation power TxBe of the antenna. Specifically, when the transmission state of the antenna changes to abnormal, the current transmission power and reception power may not meet the antenna performance requirements. In this case, it is necessary to tune the antenna in a timely manner.

[0056] According to an embodiment of the present disclosure, the transmission state of an antenna can be determined by using the standing wave ratio of the antenna. The standing wave ratio can be formed by a reflected wave, where the reflected wave is generated because the incident wave energy transmitted to the antenna input end is not completely absorbed (radiated). According to an embodiment of the present disclosure, when the standing wave ratio is greater than or equal to a threshold value S, the transmission state can be determined to be abnormal, where the value of the threshold value S can be set according to actual requirements or experience and can generally be 1.5. For example, but not limited to, when the terminal is in a hand-held state, due to changes in factors such as impedance, the TX of the antenna may be abnormal.

[0057] According to an embodiment of the present disclosure, the radiation power and reception power of the antenna under different tuning parameters can be determined in advance, or the corresponding relationship between different tuning parameters and different radiation powers and reception powers of the antenna can be determined in advance. For example, but not limited to, a chart showing the corresponding relationship between tuning parameters and radiation power and reception power as Figure 3 shown can be determined in advance. According to an embodiment of the present disclosure, although only the corresponding relationship in the form of a chart is shown in the present disclosure, the present disclosure is not limited thereto, and any appropriate form can be used to determine the corresponding relationship between tuning parameters and radiation power and reception power in advance.

[0058] When it is determined that the transmission state is abnormal, the maximum radiation power TxBe with the optimal transmission performance can be directly determined or searched for. After the maximum radiation power TxBe is determined, the dynamic tolerance relative to the maximum radiation power TxBe can be determined. In an embodiment of the present disclosure, the tolerance is defined by tolerance conditions.

[0059] In step S420, based on network parameters, the tolerance conditions for the maximum radiation power TxBe for the current service type are determined. Specifically, the tolerance conditions can be used to determine the radiation power within the dynamic tolerance range that meets the predetermined radiation power, so as to determine the corresponding tuning parameter range, and the desired reception power can be determined within the corresponding tuning parameter range.

[0060] According to an embodiment of the present disclosure, the service type can include at least one of uplink-sensitive (type) services, downlink-sensitive (type) services, and both uplink- and downlink-sensitive (type) services. Since the services of the terminal are diverse, the transmission-sensitive (type) services in the uplink-sensitive services (such as random access processes, data upload processing, etc.) require the antenna to preferentially meet the transmission performance, the reception-sensitive (type) services in the downlink-sensitive services (such as online video playback, data download, etc.) require the reception performance to be preferentially met, and the both uplink- and downlink-sensitive (type) services (such as call services, online live broadcast services, etc.) require both the transmission performance and the reception performance to be met.

[0061] Specifically, for uplink-sensitive services, the key process of signal transmission or most of the time is to send data. Whether the data sent by the terminal can reach the network device will directly affect the normal operation of the service. Therefore, it is necessary for the terminal to prioritize ensuring the transmission performance during the process of tuning the antenna. For downlink-sensitive services, the main requirement of signal transmission lies in receiving data, and the requirement for data transmission is relatively small. The normal reception and demodulation of data via the network are the keys to ensuring the normal operation of the service. Therefore, it is necessary for the terminal to prioritize ensuring the reception performance during the process of tuning the antenna. For services that are sensitive to both uplink and downlink, signal transmission needs to frequently interact with the network device. The normal transmission and reception of data will directly affect the normal operation of the service. Therefore, it is necessary for the terminal to ensure both the transmission performance and the reception performance during the process of tuning the antenna. Embodiments of the present disclosure take into account the different requirements for transmission performance or reception performance of different service types and tune the antenna based on the service type of the terminal.

[0062] In addition to considering the service type of the terminal, the present disclosure also considers the impact of the network environment on the antenna. The channel quality in the network environment may directly affect the efficiency of signal transmission and reception. According to the embodiments of the present disclosure, the uplink path loss (ULPL) indicating the uplink channel quality of the environment where the terminal is currently located can be determined based on network parameters, and the antenna can be tuned based on the uplink path loss.

[0063] Specifically, the network device carries power-related parameters of the base station (such as reference signal power, preamble reception target power, etc.) in the broadcast message, and carries power control-related parameters (such as uplink path loss correction factor, etc.) in the radio resource control (RRC) reconfiguration message or RRC Setup message. Based on the received network parameters, the downlink path loss (DLPL) of the current environment can be calculated, and the uplink path loss can be determined based on the downlink path loss.

[0064] According to the embodiments of the present disclosure, the downlink path loss can be determined by subtracting the reference signal reception strength (RSRP) of the terminal from the reference signal power of the base station.

[0065] According to the embodiments of the present disclosure, the uplink path loss can be determined by multiplying the downlink path loss by the uplink path loss correction factor.

[0066] To avoid obscuring the present disclosure with unnecessary details, the detailed details of the calculation of the downlink path loss and the uplink path loss are not described. For specific details, reference can be made to 3GPP technical specification 38.213.

[0067] According to an embodiment of the present disclosure, the value range of the uplink path loss can be empirically divided into multiple intervals respectively representing different uplink channel quality regions, such as 3 intervals. For example, but not limited to, when 95 dB < ULPL < 110 dB, the current environment can be determined as the uplink weak signal region; when 80 dB < ULP ≤ 95 dB, the current environment can be determined as the uplink medium signal region; when ULPL ≤ 80 dB, the current environment can be determined as the uplink strong signal region. The present disclosure does not limit the specific details of the division of the value range of the uplink path loss.

[0068] In addition, according to an embodiment of the present disclosure, the expected transmit power TxEx as described above can also be determined based on network parameters. Specifically, as described above, the uplink path loss and the downlink path loss can be determined based on network parameters. Further, the expected transmit power TxEx can be determined based on the uplink path loss, the downlink path loss, and other network parameters. For example, TxEx can be determined based on the maximum transmit power, the network power control parameter set, and the uplink path loss, where the network power control parameter set is related to factors such as network uplink resource scheduling and uplink power control configuration. For example, the calculated transmit power can be determined by adding the network power control parameter set to the uplink path loss. When the calculated transmit power ≥ the maximum transmit power (i.e., the maximum transmit power determined by the radio frequency link of the terminal as described above), the expected transmit power TxEx is the maximum transmit power. When the calculated transmit power < the maximum transmit power, the expected transmit power TxEx is the calculated transmit power.

[0069] Here, in order to avoid unnecessary details from obscuring the present disclosure, the detailed details of the calculation of the expected transmit power TxEx are not described. Specifically, reference can be made to 3GPP technical specification 38.213.

[0070] The present disclosure proposes to tune the antenna by simultaneously considering the service type and the network environment (such as the uplink path loss, the expected transmit power TxEx, etc.). According to an embodiment of the present disclosure, based on the uplink path loss and the expected transmit power TxEx, the tolerance condition of the maximum radiation power TxBe for the current service type is determined, where the tolerance condition can include the tolerance adjustment step size (in dB) and the tolerance adjustment range (in dB).

[0071] According to an embodiment, the tolerance adjustment step size can represent the step size for successively adjusting the tolerance. The larger the value of the tolerance adjustment step size, the greater the loss of the radiation power. Therefore, the value of the tolerance adjustment step size is the key to tuning the antenna.

[0072] According to an embodiment, the tolerance adjustment range can be associated with the tolerance adjustment step size and the tolerance adjustment times, and the radiation power within the tolerance adjustment range does not exceed the range limited by the maximum allowable tolerance (the maximum allowable tolerance = the tolerance adjustment step size × the maximum tolerance adjustment times).

[0073] The processes of determining the tolerance adjustment step size and the tolerance adjustment range will be described in detail below, respectively.

[0074] According to an embodiment of the present disclosure, the step of determining the tolerance condition of the maximum radiation power TxBe for the current service type based on the uplink path loss and the desired transmission power TxEx may include: determining the tolerance adjustment step size and the desired transmission power correction factor TxEx_offset for the current service type based on the uplink path loss. That is, the determination of the tolerance adjustment step size is determined by combining different service types and different uplink channel qualities. Here, the details of the operation of determining the desired transmission power correction factor TxEx_offset will be described in detail later, and the details of determining the tolerance adjustment step size will be described first.

[0075] For example, since the uplink-sensitive service has high requirements for the terminal transmission performance, the transmission performance needs to be as close to the optimal state as possible. Therefore, the value of the tolerance adjustment step size in the tolerance condition of the radiation power should be as small as possible. If the value of the tolerance adjustment step size is too large, it may cause too much loss of the tuned transmission performance, resulting in the transmitted data not reaching the network device or the terminal failing to access the network.

[0076] For another example, since the downlink-sensitive service should try to ensure the reception performance, and the terminal can tolerate a greater loss of transmission performance without losing synchronization with the network, the value of the tolerance adjustment step size can be set larger.

[0077] For another example, the uplink-and-downlink-sensitive service should balance the transmission performance requirements and the reception performance requirements. Therefore, the tolerance adjustment step size can be set to a value intermediate between the tolerance adjustment step sizes of the aforementioned two.

[0078] In addition, for example, for the same service type, the radiation power required by the terminal in different uplink channel quality regions is different. Generally, in order to ensure that the uplink data can reach the network device normally, the greater the uplink path loss, the greater the radiation power required by the terminal, and the corresponding value of the tolerance adjustment step size should also be dynamically adjusted to be larger. For example, when in the uplink weak signal region, the signal attenuation (or channel loss) is very large. In order to ensure that the uplink data can reach the network device normally, the loss of transmission performance should be as small as possible, so the value of the tolerance adjustment step size should be as small as possible. For another example, when in the uplink strong signal region, the signal attenuation (or channel loss) is small, and the value of the tolerance adjustment step size can be set to be larger. For another example, when in the medium signal region, the signal attenuation (or channel loss) is moderate, and the value of the tolerance adjustment step size can be set to a value intermediate between the aforementioned two.

[0079] According to an embodiment of the present disclosure, a power ratio P for tuning power corresponding to a tolerance adjustment step size can be determined. The power ratio can be associated with the radiated power after tuning and the radiated power before tuning. For example, the relationship between the power ratio P (in dB) and power can be determined by the following equation (2).

[0080] P = 10 × log(P1 / P0) (2)

[0081] Wherein, P1 can represent the radiated power after tuning, and P0 can represent the radiated power before tuning.

[0082] For example, when the radiated power after tuning is twice that before tuning (gain amplitude 100%), the power ratio P = 10 * log(2) = 3 dB.

[0083] According to an embodiment of the present disclosure, specific values of the tolerance adjustment step size corresponding to different service types and network parameters can be preset based on experience. This will be described in detail below.

[0084] In the related art, both transmit antenna diversity and uplink data retransmission mechanisms can bring gains to uplink transmission. Transmit antenna diversity transmits the same data in the frequency domain by increasing transmit antennas, and theoretically each antenna can bring a gain of about 100% (i.e., 3 dB). However, the uplink data retransmission mechanism retransmits data when the uplink data is unreachable, which is diversity in the time domain and theoretically also brings a gain of 100% (i.e., 3 dB). After tuning the antenna according to the tolerance, the transmission performance will decrease. Therefore, the gain brought by diversity cannot be fully utilized. To ensure the transmission performance, it is expected that the antenna after tuning can maintain a gain of more than 60%. Therefore, according to an embodiment of the present disclosure, the degradation of the transmission performance after each use of the tolerance adjustment step size should not exceed 40%. Correspondingly, P(dB) = 10 * log(P1 / P0) = 10 * log(0.6) = -2.2 dB. Therefore, the value of the tolerance adjustment step size should not exceed 2.2 dB at most, but this value is only an example and the present disclosure is not limited thereto.

[0085] In addition, the downlink sensitive service can allow a larger amount of transmission loss compared to the uplink sensitive service. In an embodiment of the present disclosure, the difference between the maximum tolerance adjustment step sizes for the uplink and downlink is set to 1 dB (about 20% power degradation).

[0086] Based on the above tolerance adjustment step size setting principle (i.e., not exceeding 2.2 dB), in an embodiment of the present disclosure, the maximum value of the tolerance adjustment step size is set to 2 dB, and the values of the tolerance adjustment step size for different uplink channel quality regions under the same service type are differentiated by a difference of 0.5 dB.

[0087] The corresponding relationship between the set tolerance adjustment step, service type, and uplink path loss is exemplarily shown in Table 1 below.

[0088] [Table 1]

[0089]

[0090]

[0091] In Table 1, according to the above design logic of the tolerance adjustment step varying with the service type and uplink path loss and the dB conversion principle, for example, for uplink-sensitive services, the values of the tolerance adjustment step in the uplink strong / medium / weak signal regions are respectively set to 1 dB / 0.5 dB / 0.2 dB, the corresponding Ps are respectively set to -1 dB / -0.5 dB / -0.2 dB, and the corresponding reduction amplitudes of the radiation power (or transmission performance) are approximately 20% / 10% / 5%. Similarly, for downlink-sensitive services, the values of the tolerance adjustment step under uplink strong / medium / weak signals are respectively set to 2 dB / 1.5 dB / 1 dB, and the corresponding reduction amplitudes of the transmission performance are approximately 35% / 30% / 20%. Similarly, for services sensitive to both uplink and downlink, the values of the tolerance adjustment step under uplink strong / medium / weak signals are respectively set to 1.5 dB / 1 dB / 0.5 dB, and the corresponding reduction amplitudes of the transmission performance are approximately 30% / 20% / 10%.

[0092] Although the values of the tolerance adjustment step are shown in Table 1 for different service types and uplink path losses, the above parameters are only exemplary reference values, and the present disclosure does not limit this. The values regarding the uplink path loss and the tolerance adjustment step can be adjusted according to specific implementation scenarios (such as terminal radio frequency device performance, specific scenario requirements, etc.).

[0093] In addition, the expected transmission power correction factor TxEx_offset corresponding to different service types and channel quality regions is also shown in Table 1, which will be described now.

[0094] In the present disclosure, when tuning the antenna, considering the complexity of the environment and the diversity of service types, the above-determined expected transmission power TxEx may deviate from the transmission power actually required by the terminal. As a result, there may be a situation where, after determining the tuning parameters based on the tolerance and adjusting the antenna, a suitable antenna efficiency still cannot be obtained. For this reason, the present disclosure also proposes to use the expected transmission power correction factor (also referred to as the "power offset") TxEx_offset to adjust the expected transmission power TxEx. As described above, the expected transmission power correction factor TxEx_offset for the expected transmission power TxEx of the current service type can be determined based on the uplink path loss.

[0095] According to an embodiment of the present disclosure, TxEx_offset can be used to represent a compensation coefficient for ensuring antenna performance (especially transmission performance). Considering that the requirements for transmission performance are different when performing services of different service types, different TxEx_offsets are set for different service types. Among them, the TxEx_offset of the uplink-sensitive service < the TxEx_offset of the uplink-and-downlink-sensitive service < the TxEx_offset of the downlink-sensitive service.

[0096] In addition, as described above, due to the limitation of TxEx, the antenna efficiency may still be inappropriate after tuning. In the present disclosure, by performing another tuning, the probability of obtaining an appropriate antenna efficiency will increase. Therefore, the value-taking principle of TxEx_offset also depends on compensating for a tolerance adjustment step (that is, additionally adding a round of tuning process based on the tolerance adjustment step).

[0097] According to the embodiment, the TxEx_offset for the current service type can be determined based on the uplink path loss. Optionally, the TxEx_offset can also be determined only based on the service type. Table 1 exemplarily shows the correspondence between TxEx_offset and the service type. In Table 1, only the case where the value of TxEx_offset depends on the service type and the tolerance adjustment step is shown. Among them, the TxEx_offset of the uplink-sensitive service is set to be the same as the value of the tolerance adjustment step in the uplink strong signal area. In Table 1, the TxEx_offset values of the uplink-sensitive service / downlink-sensitive service / uplink-and-downlink-sensitive service are set to 1 dB / 2 dB / 1.5 dB respectively. Although the value-taking of TxEx_offset under different service types is shown in Table 1, the above parameters are only exemplary reference values, and the present disclosure does not limit this. The value of TxEx_offset can be adjusted according to specific implementation scenarios (such as the performance of the terminal radio frequency device, specific scenario requirements, etc.).

[0098] In addition, in the present disclosure, a process of dynamically adjusting the tolerance is proposed. Therefore, in addition to determining the tolerance adjustment step included in the tolerance condition, it is also necessary to dynamically determine the tolerance adjustment range included in the tolerance condition.

[0099] According to the embodiment, the tolerance adjustment range is determined based on the expected transmission power TxEx and the expected transmission power correction coefficient TxEx_offset.

[0100] According to an embodiment, the tolerance adjustment range can be understood as a power value range of the radiation power dynamically determined based on the tolerance adjustment step, and the difference between the maximum value and the minimum value of the power value range is equal to the tolerance adjustment step. As described above, since the tolerance adjustment range can be associated with the tolerance adjustment step and the number of tolerance adjustments t and is limited by the maximum allowable tolerance, therefore, first, the limiting conditions of the tolerance adjustment range can be indirectly determined by determining the maximum number of tolerance adjustments related to the maximum allowable tolerance, and then the corresponding tolerance range can be determined.

[0101] The relationship between the tolerance adjustment step step, the maximum number of tolerance adjustments n, TxEx, and TxEx_offset can be defined by the following equation (3):

[0102] TxBe – step × n ≥ TxEx × η – TxEx_offset (3)

[0103] Wherein, TxBe can be the maximum radiation power, step can represent the tolerance adjustment step, n can represent the maximum number of tolerance adjustments, TxEx can be the desired transmission power, η can be the antenna efficiency conversion rate, and TxEx_offset can be the desired transmission power correction factor.

[0104] In equation (3), when the difference between the maximum radiation power TxBe and a certain radiation power is greater than step × n, this radiation power may not meet the emission performance requirements, and therefore, the tuning parameters corresponding to this radiation power are not allowed.

[0105] Through equation (3), step × n can represent the maximum allowable tolerance, and by dividing the result of TxBe – TxEx × η + TxEx_offset by the tolerance adjustment step step, the maximum value of n as a positive integer can be obtained. Correspondingly, the minimum value of the tolerance adjustment range must be greater than or equal to TxEx × η – TxEx_offset.

[0106] Hereinafter, n is the maximum number of times to perform the process of successively determining the candidate reception power based on the tolerance adjustment step. After determining the limiting conditions of the number of tolerance adjustments t related to the tolerance adjustment range, the tolerance adjustment range can be determined.

[0107] According to an embodiment, the tolerance adjustment range is related to the tolerance adjustment step and the number of tolerance adjustments. For the sake of convenience of description, the radiation power within the tolerance adjustment range can be referred to as the candidate radiation power. According to an embodiment, the difference between TxBe and the radiation candidate power of the t-th tolerance adjustment is between the product of the tolerance adjustment step and (t - 1) and the product of the tolerance adjustment step and t, where t is a positive integer greater than or equal to 1 and less than or equal to n.

[0108] For example, the tolerance conditions may include, but are not limited to: at the t-th tolerance adjustment, the difference between the maximum radiation power TxBe and the candidate radiation power Tx within the tolerance adjustment range is less than or equal to the product of the tolerance adjustment step size and t and greater than the product of the tolerance adjustment step size and (t - 1). The candidate radiation power Tx for the tolerance condition of the t-th tolerance adjustment t can be expressed as the following equation (4): t can be expressed as the following equation (4):

[0109] TxBe – t × step ≤ Tx t <TxBe – (t - 1) × step (4)

[0110] where TxBe is the maximum radiation power, step is the tolerance adjustment step size, and t is a positive integer greater than or equal to 1 and less than or equal to n.

[0111] In other words, the tolerance adjustment range can be a range of power values corresponding to the t-th tolerance adjustment step size step based on the number of tolerance adjustment times t.

[0112] According to the embodiment, at the first tolerance adjustment, the candidate radiation power Tx t may include TxBe. That is, when determining the tolerance adjustment range for the first time, TxBe can be included in the radiation power that satisfies the tolerance conditions.

[0113] In this way, based on the uplink path loss, the tolerance adjustment step size and the desired transmit power correction factor TxEx_offset for the current service type can be determined, and based on the desired transmit power TxEx and the desired transmit power correction factor TxEx_offset, the tolerance adjustment range can be determined, so as to determine the tolerance conditions for the maximum radiation power TxBe of the current service type.

[0114] Return reference Figure 4 , at step S430, based on the tolerance conditions, the target received power is determined. Specifically, based on the tolerance conditions, a plurality of radiation powers that satisfy the tolerance conditions can be determined. The determined plurality of radiation powers can correspond to a plurality of tuning parameters (or tuning parameter intervals) and corresponding plurality of received powers, and the target received power (i.e., the expected received power after adjusting the tuning parameters) is determined from the plurality of received powers.

[0115] According to an embodiment of the present disclosure, based on the tolerance adjustment step size, candidate received powers are successively determined from the plurality of received powers corresponding to the plurality of radiation powers within the tolerance adjustment range; the candidate received powers that satisfy the preset conditions are determined as the target received power. Now refer to Figure 5 for an exemplary description of determining the target received power.

[0116] Figure 5is a diagram showing an example of determining a target received power according to an embodiment of the present disclosure. In Figure 5 it, it is assumed that the current service type is an uplink-sensitive service, and it is assumed that the tolerance adjustment step size is 1 dB.

[0117] Referring to Figure 5 , the horizontal axis of the graph represents a tuning parameter, and the vertical axis of the graph represents a power value or a block error rate (BLER) value. For example, for the radiation power, the vertical axis of the graph represents a power value (in dB), and for the block error rate, the vertical axis of the graph represents a percentage value of the block error rate.

[0118] According to an embodiment of the present disclosure, the step of successively determining a candidate received power from among a plurality of received powers corresponding to a plurality of radiation powers within a tolerance adjustment range based on a tolerance adjustment step size may include: in the t-th determination process (where t is a positive integer less than or equal to the value of n as described above), determining the maximum received power among the plurality of received powers corresponding to the plurality of radiation powers within the tolerance adjustment range in the t-th determination process as the candidate received power.

[0119] Specifically, according to an embodiment, in the first determination (or tolerance adjustment) process, the maximum received power among the plurality of radiation powers within the tolerance adjustment range defined by the first tolerance adjustment step size and the plurality of received powers corresponding to the TxBe is determined as the candidate received power. For example, referring to Figure 5 , the tolerance adjustment range indicated by "1 dB tolerance" may represent the range of radiation powers that satisfy the tolerance condition in the first determination process. By finding the maximum received power among the received powers corresponding to the radiation powers within this range, a candidate received power with a tuning parameter of 41 can be determined.

[0120] Specifically, according to an embodiment, in the second determination (or tolerance adjustment) process, the maximum received power among the plurality of received powers corresponding to the plurality of radiation powers within the tolerance adjustment range defined by the second tolerance adjustment step size is determined as the candidate received power. For example, referring to Figure 5 , in the first determination (or tolerance adjustment) process, the tolerance adjustment range is the range of radiation power from 15 to 14, and in the second determination (or tolerance adjustment) process, the tolerance adjustment range is the range of radiation power from 14 to 13, and so on, but the tolerance adjustment range does not exceed the range defined by the maximum allowable tolerance.

[0121] Similarly, and so on, a candidate received power is determined within the tolerance adjustment range defined by the t-th tolerance adjustment step size until a candidate received power that satisfies a preset condition is determined, or until the maximum number of tolerance adjustment times is reached, and the process of determining the candidate received power is stopped.

[0122] As described above, the candidate received power can be determined successively, and the candidate received power that meets the preset conditions is determined as the target received power. To ensure the stability of signal transmission for services, the tuning parameters are also determined based on the block error rate (BLER).

[0123] According to an embodiment of the present disclosure, based on the tolerance adjustment step size, the candidate received power is successively determined among the multiple received powers corresponding to the multiple radiation powers within the tolerance adjustment range; in each determination process, when the received power of the antenna is the determined candidate received power, if the block error rate corresponding to the received power meets the preset conditions, the determination process of the candidate received power is ended and the currently determined candidate received power is determined as the target received power. That is, the candidate received power is determined cyclically based on the tolerance conditions multiple times. Once the block error rate corresponding to the candidate received power in a certain determination process meets the preset conditions of the block error rate, it is determined that the radiation power and received power in the optimal state are found.

[0124] The preset conditions for the block error rate may include: when the received power of the antenna is the candidate received power, the uplink block error rate and the downlink block error rate within a predetermined time period meet the block error rate requirements corresponding to the current service type.

[0125] According to an embodiment of the present disclosure, the block error rate requirements may include the uplink block error rate (UL BLER) condition and / or the downlink block error rate (DL BLER) requirements. Among them, the uplink block error rate requirement may include that the uplink block error rate is less than the uplink block error rate threshold B0, and the downlink block error rate requirement may include that the downlink block error rate is less than the downlink block error rate threshold B1. For example, but not limited to, in each determination process, the uplink block error rate and the downlink block error rate based on the determined candidate received power and the corresponding radiation power are monitored, and it is determined whether the block error rate requirements are met.

[0126] Since different services have different requirements for the uplink and downlink block error rates, according to an embodiment of the present disclosure, the block error rate thresholds in the block error rate conditions can be determined based on the service type. For example, Table 2 exemplarily shows an example of the service type and the block error rate thresholds.

[0127] [Table 2]

[0128] Service type B0 B1 Uplink-sensitive service 10％ 20％ Downlink-sensitive service 20％ 10％ Both uplink and downlink-sensitive service 10％ 10％

[0129] According to Table 2, when the service type is determined, the uplink block error rate threshold B0 and / or the downlink block error rate threshold B1 in the block error rate requirements for the current service type can be correspondingly determined. Although the values of different block error rate thresholds are shown in Table 2, the above parameters are only exemplary reference values, and the present disclosure does not limit this. The values of the block error rate thresholds can be adjusted according to specific implementation scenarios (for example, but not limited to, the actual channel environment).

[0130] Refer to Figure 5 , assuming that both the uplink block error rate threshold B0 and the downlink block error rate threshold B1 are 3% (i.e., the dashed line with a vertical axis value of 3 in Figure 5 ).

[0131] According to an embodiment of the present disclosure, in each determination process, if the block error rate corresponding to the determined candidate received power meets the block error rate requirement, the step of ending the determination process of the candidate received power and determining the determined candidate received power as the target received power may include: in each determination process, determining the uplink block error rate and the downlink block error rate within a predetermined time period when the received power of the antenna is the candidate received power; when the uplink block error rate and the downlink block error rate meet the error rate requirement corresponding to the current service type, ending the determination process of the candidate power and determining the candidate received power as the target received power.

[0132] Specifically, as described above, in each determination process, the candidate received power and the radiation power corresponding to the candidate received power may be determined. Correspondingly, the uplink block error rate and the downlink block error rate within a predetermined time period (for example, but not limited to, 2 seconds) may be monitored and counted. For example, refer to Figure 5 , in the first determination process, the candidate received power with a tuning parameter of 41 is determined. However, the uplink block error rate corresponding to the tuning parameter 41 is greater than 3%, that is, it does not meet the preset condition. Therefore, the next loop process is continued (i.e., t = t + 1).

[0133] Specifically, in the second loop determination process, the maximum received power among the multiple received powers corresponding to the multiple radiation powers within the tolerance adjustment range is determined as the candidate received power, where the tolerance condition is that the difference between TxBe and the radiation power is greater than the tolerance adjustment step and less than or equal to the tolerance adjustment step × 2. For example, refer to Figure 5 , the range of 1 dB in the lower half of the range indicated by "2 dB tolerance" may represent the range of the radiation power that meets the tolerance condition in the second loop determination process. Find the maximum received power within this range and determine the candidate received power with a tuning parameter of 72. In the case where the tuning parameter is 72, both the uplink block error rate and the downlink block error rate meet the block error rate condition. Therefore, the candidate received power with a tuning parameter of 72 is determined as the target received power, and the determination process ends.

[0134] Return Figure 4 , in step S440, the tuning parameter corresponding to the target received power is determined as the tuning parameter of the antenna.

[0135] The antenna tuning method according to an embodiment of the present disclosure can dynamically tune the antenna based on the service type and network environment, and can adjust both the transmission performance and the reception performance of the antenna to the optimal balanced state to the greatest extent, avoiding the loss of transmission performance or reception performance caused by tuning with a fixed tolerance. In addition, by using the block error rate to determine the optimal reception power, the stability of the service can be ensured while ensuring the optimal performance of the antenna, thereby improving the transmission quality.
