[0032] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0033] The uplink antenna diversity switching method provided by the present disclosure is applied to a scenario where a terminal performs uplink antenna switching, for example, a scenario where a mobile phone performs uplink antenna switching.

[0034] At present, the terminal can use the Antenna Switching Diversity (ASDiv) algorithm to select the antenna. The ASDiv algorithm refers to the modem (modulator-demodulator, Modem) periodically calculating the difference in received signals between the main set receiving antenna and other diversity receiving antennas. If the difference in received signals between the main set receiving antenna and other diversity receiving antennas is greater than the switching threshold, the transmitting antenna is switched to the diversity receiving antenna. Among them, the antenna where the transmitting antenna is located is the main set receiving antenna.

[0035] However, the current ASDiv algorithm does not take into account the antenna consistency problem, that is, the best antenna reception performance does not necessarily mean that its transmission performance is also the best. For example, the antenna consistency problem has a great impact on the frequency band in the frequency division duplex (FDD) mode. Since the uplink and downlink channels of the FDD band are located at different frequencies, the uplink and downlink performance indicators of the same antenna are different. As shown in Table 1,

[0036]

[0037] Table 1

[0038] Table 1 is a performance index table of the closed left hand holding uplink frequency EARFCN=19575 and downlink frequency EARFCN=1575, as shown in Table 1, where ANT represents the antenna, for example, ANT1 represents antenna 1. The corresponding frequency is represented by the frequency number (E-UTRA Absolute Radio Frequency Channel Number, EARFCN), when the uplink frequency is EARFCN=19575, the best antenna reception performance index is ANT3=16.9, that is, the reception performance index of antenna 3 is the best, which is 16.9dBm, however, the transmission performance index corresponding to antenna 3 is not the best, and the transmission performance index corresponding to antenna 4 is the best.

[0039] Therefore, due to the inconsistency between the receiving performance index and the transmitting performance index of the same antenna, there will be errors in determining whether to switch antennas based on the difference in received signals between receiving antennas, which may cause the receiving performance of the switched antenna to deteriorate, thereby causing uplink antenna imbalance (Up Link Imbalance, UL Imbalance) problems.

[0040] As for the UL Imbalance problem, the present invention discloses that the current hand gesture holding posture of the terminal, the current communication service scenario of the terminal, and the current frequency band in which the terminal conducts communication services, and determines the antenna received signal strength value for antenna diversity switching based on the identified current hand gesture holding posture, the current communication service scenario, and the current frequency band, and performs uplink antenna diversity switching according to the antenna received signal strength value, thereby solving the uplink antenna imbalance problem, optimizing the antenna diversity switching scheme, and more accurately selecting the optimal antenna in the current scenario.

[0041] Figure 1 is a flow chart of an uplink antenna diversity switching method according to an exemplary embodiment. Figure 1 As shown, the uplink antenna diversity switching method is used in a terminal, comprising the following steps:

[0042] In step S11, the current hand gesture of the terminal being held, the current communication service scenario of the terminal, and the current frequency band in which the terminal performs communication services are identified.

[0043] In step S12, the antenna received signal strength value for antenna diversity switching is determined based on the current hand gesture, the current communication service scenario, and the current frequency band, and uplink antenna diversity switching is performed according to the antenna received signal strength value.

[0044] The main set of receiving antennas may be the antennas where the transmitting antennas are located.

[0045] The diversity receiving antenna may be an antenna other than the antenna where the transmitting antenna is located.

[0046] In the disclosed embodiment, the current gesture grip posture can be determined based on a gesture recognition self-learning algorithm through at least one of a Hall sensor, a Specific Absorption Rate (SAR) sensor, and a Gravity sensor (G-sensor).

[0047] In the embodiment of the present disclosure, the current grip posture of the terminal being held may be a closed left-hand grip or an open two-hand grip, and the current grip posture of the terminal being held is not limited.

[0048] In the embodiment of the present disclosure, the receiving signal of the main receiving antenna and the receiving signals of each diversity receiving antenna are determined based on the current hand gesture, the current communication service scenario and the current frequency band, and the difference between the receiving signal of each diversity antenna and the receiving signal of the main receiving antenna is obtained and compared with the threshold. If the difference between the receiving signal of the diversity receiving antenna and the receiving signal of the main receiving antenna is greater than the threshold, the transmitting antenna is switched to the diversity receiving antenna; if the difference between the receiving signal of the diversity receiving antenna and the receiving signal of the main receiving antenna is less than or equal to the threshold, the transmitting antenna is not switched.

[0049] In the embodiment of the present disclosure, if the difference between the received signal of a diversity receiving antenna and the received signal of the main receiving antenna is greater than a threshold, the transmitting antenna is switched to the diversity receiving antenna.

[0050] In the disclosed embodiment, there may be two or more diversity receiving antennas whose received signals have a difference greater than a threshold value with respect to the received signal of the main receiving antenna, and the diversity receiving antenna corresponding to the maximum difference value is selected. For example, the threshold for antenna switching, i.e., the antenna switching threshold, may be 3dB. The difference between the received signals of diversity receiving antenna 1 and the main receiving antenna is 3.1dB, the difference between the received signals of diversity receiving antenna 2 and the main receiving antenna is 3.5dB, and the difference between the received signals of diversity receiving antenna 3 and the main receiving antenna is 5dB. The difference between diversity receiving antenna 3 and the main receiving antenna is the largest, and diversity receiving antenna 3 is selected as the switching antenna for uplink antenna diversity switching.

[0051] In the embodiments of the present disclosure, by identifying the current gesture holding posture of the terminal, the current communication service scenario of the terminal, and the current frequency band in which the terminal conducts communication services, and determining the antenna reception signal strength value for antenna diversity switching based on the current gesture holding posture, the current communication service scenario, and the current frequency band, the antenna reception signal strength value for antenna diversity switching is determined to be more in line with the current gesture holding posture, the communication service scenario, and the frequency band, thereby ensuring that the uplink antenna diversity switching that is more in line with the current gesture holding posture, the current communication service scenario, and the current frequency band can be performed based on the antenna reception signal strength value.

[0052] In the disclosed embodiment, the compensation value corresponding to the current gesture grip and the current frequency band can be preset based on the current gesture grip and the current frequency band. According to the current communication service scenario, the compensation value corresponding to the current communication service scenario is retrieved.

[0053] Figure 2 is a flow chart of an uplink antenna diversity switching method according to an exemplary embodiment. Figure 2 As shown, the uplink antenna diversity switching method is used in a terminal, comprising the following steps:

[0054] In step S21, based on the correspondence between the frequency band, the hand gesture and the compensation value, the compensation value corresponding to the current frequency band and the current hand gesture is determined.

[0055] In step S22, based on the compensation value and the current communication service scenario, the antenna received signal strength value is compensated, and based on the compensated antenna received signal strength value, the transmit antenna diversity switching is performed.

[0056] In the embodiment of the present disclosure, based on the current frequency band and the current hand gesture, the antenna performance index value corresponding to the current frequency band and the current hand gesture is obtained, and the difference between the antenna performance index value corresponding to the main set receiving antenna and the performance index value corresponding to the diversity receiving antenna is used as the compensation value.

[0057] The compensation value may be a positive value.

[0058] The compensation value may be a negative value.

[0059] In the embodiment of the present disclosure, based on the current communication service scenario, a compensation value determined by the current frequency band and the current hand gesture is selected, and based on the selected compensation value, the antenna received signal strength value is compensated.

[0060] In the disclosed embodiment, the antenna received signal strength value may be compensated by subtracting the antenna received signal strength value from the selected compensation value, and the difference between the antenna received signal strength value and the selected compensation value may be used as the compensated antenna received signal.

[0061] In the disclosed embodiment, the difference between the received signal strength value of the compensated diversity receiving antenna and the received signal strength value of the compensated main receiving antenna is compared with the switching threshold. If the difference is greater than the switching threshold, the transmitting antenna is switched to the diversity receiving antenna; if the difference is less than or equal to the switching threshold, the transmitting antenna is not switched.

[0062] In one scenario, when the compensation value is a positive value, the difference between the received signal strength value of the compensated diversity receiving antenna and the received signal strength value of the compensated main receiving antenna is smaller than the difference between the received signal strength value of the uncompensated diversity receiving antenna and the received signal strength value of the uncompensated main receiving antenna. Therefore, the difficulty of switching the transmitting antenna to the diversity receiving antenna increases.

[0063] In one scenario, when the compensation value is a negative value, the difference between the received signal strength value of the compensated diversity receiving antenna and the received signal strength value of the compensated main receiving antenna is greater than the difference between the received signal strength value of the uncompensated diversity receiving antenna and the received signal strength value of the uncompensated main receiving antenna. Therefore, the difficulty of switching the transmitting antenna to the diversity receiving antenna is reduced.

[0064] In the disclosed embodiment, the compensation value determined based on the correspondence between the frequency band, the hand gesture and the compensation value can better reflect the antenna performance in the current frequency band and the current hand gesture, thereby ensuring that the antenna receiving signal strength value compensated based on the compensation value and the current communication service scenario can better reflect the performance of the current antenna, thereby enabling the switched transmitting antenna to be located at the most suitable antenna in the current scenario.

[0065] In the embodiment of the present disclosure, the compensation value may be an uplink performance indicator compensation value and a downlink performance indicator compensation value.

[0066] In the embodiment of the present disclosure, the current communication service scenario may include a target communication service scenario or a non-target communication service scenario.

[0067] In the disclosed embodiment, the corresponding compensation value is matched according to the current communication service scenario. When the current communication service scenario is a target communication service scenario, the compensation value matched to the current communication service scenario is a downlink performance index compensation value; or when the current communication service scenario is a non-target communication service scenario, the compensation value matched to the current communication service scenario is an uplink performance index compensation value. Then, according to the compensation value matched to the service scenario, the antenna received signal strength value is compensated.

[0068] Figure 3 is a flow chart of a method for performing uplink antenna diversity switching based on a compensation value matched to a communication service scenario according to an exemplary embodiment. Figure 3 As shown, the uplink antenna diversity switching method is used in a terminal, comprising the following steps:

[0069] In step S31, in response to the current communication service scenario being a target communication service scenario, the compensation value matching the current communication service scenario is determined to be a downlink performance indicator compensation value; or in response to the current communication service scenario being a non-target communication service scenario, the compensation value matching the current communication service scenario is determined to be an uplink performance indicator compensation value.

[0070] Among them, the target communication service scenario is a communication scenario in which the downlink service data volume is greater than the uplink service data volume.

[0071] In step S32, the antenna received signal strength value is compensated according to a compensation value matching the current communication service scenario.

[0072] In the disclosed embodiment, the downlink performance index compensation value is determined based on the total isotropic sensitivity (TIS) of the antenna, wherein the total isotropic sensitivity of the antenna represents the antenna receiving performance index.

[0073] In the disclosed embodiment, the uplink performance index compensation value is determined based on the total radiated power (TRP) of the antenna, wherein the total radiated power of the antenna represents the antenna transmission performance index.

[0074] In one example, the current communication service scenario is the target communication service scenario, and the compensation value matching the current communication service scenario is determined to be the downlink performance index compensation value. The difference between the antenna received signal strength value and the downlink performance index compensation value is used as the compensated antenna received signal strength value.

[0075] The downlink performance compensation value may be used to optimize the downlink antenna reception performance.

[0076] In one example, the current communication service scenario is a non-target communication service scenario, and the compensation value matching the current communication service scenario is determined to be an uplink performance index compensation value. The difference between the antenna received signal strength value and the uplink performance index compensation value is used as the compensated antenna received signal strength value.

[0077] Among them, the uplink performance indicator compensation value can be used to optimize the antenna uplink transmission performance.

[0078] In the disclosed embodiment, the antenna received signal strength value is compensated according to the current communication service scenario and the compensation value matching the current communication service scenario, so that the antenna can obtain a compensation value that is more in line with the current communication service scenario, so that the compensated antenna received signal strength value can better reflect the corresponding antenna performance of the current communication service scenario.

[0079] In the embodiment of the present disclosure, the target communication service scenario is a communication scenario in which the amount of downlink service data is greater than the amount of uplink service data, wherein the amount of downlink service data is greater than the amount of uplink service data can be represented by at least one of the following:

[0080] The current throughput is greater than the preset throughput threshold;

[0081] The signal-to-noise ratio is greater than zero, and the signal strength value is greater than a preset signal strength threshold;

[0082] The block error rate is greater than a preset block error rate threshold.

[0083] The throughput (Throughput, Tput) indicates the amount of successfully transmitted data per unit time. The throughput preset threshold may be a minimum throughput, for example, the throughput preset threshold is set to 1 Mbps.

[0084] Among them, the signal-to-noise ratio (SNR) reflects the content of impurities in the signal. The larger the SNR, the less impurities in the signal, and the better the signal quality. The reference signal receiving power (RSRP) indicates the signal strength.

[0085] The Block Error Ratio (BLER) refers to the error probability of a transmission block after verification.

[0086] In the embodiments of the present disclosure, the uplink antenna diversity switching method is described in conjunction with the following examples.

[0087] The calculation of the compensation value is described by taking the current hand gesture grip as a closed left hand grip, the current uplink frequency point as EARFCN=19575, and the current downlink frequency point as EARFCN=1575 as an example.

[0088] In the disclosed embodiment, the current hand gesture and holding posture of the terminal, the current communication service scenario of the terminal, and the current frequency band in which the terminal performs communication services are identified.

[0089] in, Figure 4 is a schematic diagram showing a method for identifying a hand gesture and grip posture and obtaining a compensation value based on the hand gesture and grip posture, frequency band and terminal call service scenario according to an exemplary embodiment, such as Figure 4 As shown, corresponding data is obtained through at least one of a Hall sensor, a Specific Absorption Rate (SAR) sensor, and a Gravity sensor (G-sensor), and based on the obtained data, a gesture recognition self-learning algorithm determines the current gesture grip.

[0090] Based on the current hand gesture and the current frequency band where the terminal is communicating, the antenna provides Over The Air (OTA) data. The OTA data provided by the antenna includes downlink performance indicators determined based on the total omnidirectional sensitivity of the antenna and uplink performance indicators determined based on the total radiated power of the antenna.

[0091] Table 2 is a table of antenna performance indicator data according to an exemplary embodiment, where the hand gesture grip is a closed left hand grip, the current uplink frequency band of the communication service is 19575dB, and the downlink frequency band is 1575dB.

[0092]

[0093] Table 2

[0094] In the disclosed embodiment, the uplink performance index is a positive value. The larger the uplink performance index is, the better the antenna transmission performance is. The downlink performance index is a negative value. The smaller the data value is, the better the antenna reception performance index is. For example, as shown in Table 2, the uplink performance index of antenna 3 is the largest, which means that antenna 3 has the best transmission performance index in the current scenario. When the downlink frequency is 1575, in the closed left hand holding scenario, the downlink performance index of antenna 4 is the smallest, which means that antenna 4 has the best reception performance index in the current scenario.

[0095] In the disclosed embodiment, the hand gesture grip is a closed left hand grip, the current uplink frequency point of the communication service is EARFCN=19575dB, and the downlink frequency point is EARFCN=1575dB, the uplink performance index compensation value can be calculated as follows:

[0096] Where Tx represents the strength value of the transmitting antenna. rx represents the strength value of the receiving antenna, where rx0 represents the strength value of the main receiving antenna, and rx1-rx3 represent the strength values ​​of the diversity receiving antenna. ANT2, ANT3, ANT4, ANT0 correspond to antenna 2, antenna 3, antenna 4, antenna 0. txM_rxN_imb represents the compensation value when the transmitting antenna M switches to the receiving antenna N. TRP_ANTu represents the uplink performance index on antenna u. TIS_ANTv represents the downlink performance index on antenna v.

[0097] For example, Tx-ANT2 indicates that the antenna corresponding to Tx and the antenna corresponding to rx0 are currently ANT2, and the antennas corresponding to the remaining rx1 / rx2 / rx3 are ANT3 / ANT4 / ANT0 respectively.

[0098] tx0_rx0_imb=0, since the antenna corresponding to Tx is bound to the antenna corresponding to rx0, the compensation value when Tx (ANT2) switches to rx0 (ANT2) is 0dB;

[0099] tx0_rx1_imb=TRP_ANT2–TRP_ANT3=16.5-17.2=-0.7dB, that is, the compensation value when Tx(ANT2) switches to rx1(ANT3) is -0.7dB;

[0100] tx0_rx2_imb=TRP_ANT2–TRP_ANT4=16.5-15.7=0.8dB, that is, the compensation value when Tx(ANT2) switches to rx2(ANT4) is 0.8dB;

[0101] tx0_rx3_imb = TRP_ANT2 – TRP_ANT0 = 16.5-14.8 = 1.7dB, that is, the compensation value when Tx (ANT2) switches to rx2 (ANT4) is 1.7dB;

[0102] Tx-ANT3 indicates that the antenna corresponding to Tx and the antenna corresponding to rx0 are currently ANT3, and the antennas corresponding to the remaining rx1 / rx2 / rx3 are ANT2 / ANT4 / ANT0 respectively.

[0103] tx0_rx0_imb=0, since the antenna corresponding to Tx is bound to the antenna corresponding to rx0, the compensation value when Tx (ANT3) switches to rx0 (ANT3) is 0dB;

[0104] tx0_rx1_imb=TRP_ANT3–TRP_ANT2=17.2-16.5=0.7dB, that is, the compensation value when Tx(ANT3) switches to rx1(ANT2) is 0.7dB;

[0105] tx0_rx2_imb=TRP_ANT3–TRP_ANT4=17.2-15.7=1.5dB, that is, the compensation value when Tx(ANT2) switches to rx2(ANT4) is 1.5dB;

[0106] tx0_rx3_imb = TRP_ANT3 – TRP_ANT0 = 17.2-14.8 = 2.4dB, that is, the compensation value when Tx (ANT2) switches to rx2 (ANT4) is 2.4dB;

[0107] Similarly, when the antennas corresponding to Tx are ANT4 and ANT0 in the current scenario, the uplink performance indicator compensation values ​​when the antennas corresponding to Tx are switched to the remaining antennas can be calculated.

[0108] In the embodiment of the present disclosure, the downlink performance indicator compensation value can be calculated as follows:

[0109] Tx-ANT2 indicates that the antenna corresponding to Tx and the antenna corresponding to rx0 are currently ANT2, and the antennas corresponding to the remaining rx1 / rx2 / rx3 are ANT3 / ANT4 / ANT0 respectively.

[0110] tx0_rx0_imb=0, since the antenna corresponding to Tx is bound to the antenna corresponding to rx0, the compensation value when Tx (ANT2) switches to rx0 (ANT2) is 0dB;

[0111] tx0_rx1_imb=TIS_ANT2–TIS_ANT3=|-86.8|-|-87.3|=-0.5dB, that is, the compensation value when Tx(ANT2) switches to rx1(ANT3) is -0.5dB;

[0112] tx0_rx2_imb=TRP_ANT2–TRP_ANT4=|-86.8|-|-88.6|=-1.8dB, that is, the compensation value when Tx(ANT2) switches to rx2(ANT4) is -1.8dB;

[0113] tx0_rx3_imb=TRP_ANT2–TRP_ANT0=|-86.8|-|-85.8|=1dB, that is, the compensation value when Tx(ANT2) switches to rx2(ANT4) is 1dB;

[0114] Similarly, when the antennas corresponding to Tx in the current scenario are ANT3, ANT4, and ANT0, the downlink performance indicator compensation values ​​when the antennas corresponding to Tx are switched to the remaining antennas can be calculated.

[0115] When the hand gesture is closed left hand grip, the current uplink frequency point of the communication service is EARFCN=19575dB, and the downlink frequency point is EARFCN=1575dB, the calculated uplink performance index compensation value and downlink performance index compensation value are sorted out to obtain the compensation value data table shown in Table 3.

[0116]

[0117] Table 3

[0118] Table 3 is a compensation value data table showing a hand gesture grip of a closed left hand grip, a current uplink frequency point of a communication service of EARFCN=19575dB, and a downlink frequency point of EARFCN=1575dB according to an exemplary embodiment.

[0119] In the disclosed embodiment, the ASDiv judgment may be in response to the current communication service scenario being a target communication service scenario, determining that the compensation value matching the current communication service scenario is a downlink performance indicator compensation value; or in response to the current communication service scenario being a non-target communication service scenario, determining that the compensation value matching the current communication service scenario is an uplink performance indicator compensation value.

Figure 5 As shown, the method for executing the transmit antenna diversity switching decision is used in the terminal, comprising the following steps:

[0122] In step S42, upper layer gesture recognition is performed.

[0123] Among them, the current gesture holding posture of the terminal can be identified through sensors and self-learning algorithms.

[0124] In step S43, the modem presets uplink antenna imbalance compensation values ​​under different frequency points.

[0125] The uplink antenna imbalance compensation value (Up Link Imbalance, UL Imbalance) may include an uplink performance index compensation value determined based on the antenna total radiated power (TRP) and a downlink performance index compensation value determined based on the antenna total omnidirectional sensitivity (TIS).

[0126] Among them, the modem simultaneously obtains the uplink performance index compensation value determined based on the total antenna radiation power and the downlink performance index compensation value determined based on the total omnidirectional sensitivity of the antenna according to the current gesture holding posture of the terminal recognized by the sensor and the self-learning algorithm, as well as the current frequency band.

[0127] In step S44, the modem determines whether the current service scenario is a downlink service data heavy scenario (heavy Down Link traffic, heavy DL traffic).

[0128] If it is determined that the current service scenario is a downlink service data-heavy scenario, step S451 is executed to call the compensation value based on the total omnidirectional sensitivity of the antenna under the gesture corresponding to the frequency point.

[0129] If it is determined that the current service scenario is not a downlink service data-heavy scenario, step S452 is executed to call the compensation value based on the total antenna radiation power under the gesture corresponding to the frequency point.

[0130] In step S46, end.

[0131] In the disclosed embodiment, a corresponding compensation value is determined by the current communication service scenario, and then the antenna received signal strength value is compensated according to the compensation value determined by the current communication service scenario.

[0132] In the disclosed embodiment, the current communication service scenario is determined to be a non-target communication service scenario, that is, a communication scenario in which the downlink service data volume is less than or equal to the uplink service data volume. Based on the current non-target communication service scenario, it is determined to adopt an uplink performance index compensation value, and the antenna received signal strength value is compensated based on the uplink performance index compensation value, so as to perform uplink antenna diversity switching according to the compensated antenna received signal strength value.

[0133] In one scenario, taking the gesture grip as a closed left hand grip, the current uplink frequency point of the communication service is EARFCN=19575dB, and the downlink frequency point is EARFCN=1575dB as an example, the uplink performance index compensation value of the antenna corresponding to Tx on ANT4 in Table 3 is used for explanation.

[0134] The switching threshold may be 3dB.

[0135] The antenna corresponding to the current Tx is ANT4, and the signal strength values ​​of each receiving antenna received by the modem are:

[0136] rx0(ANT4)=-100dBm, rx1(ANT3)=-98dBm,

[0137] rx2(ANT2)=-101dBm, rx3(ANT0)=-102dBm

[0138] If the row performance index compensation value is not added, due to

[0139] rx1(ANT3)-rx0(ANT4)=(-98)-(-100)=2dB,

[0140] rx2(ANT3)-rx0(ANT4)=(-101)-(-100)=1dB,

[0141] rx3(ANT3)-rx0(ANT4)=(-102)-(-100)=-2dB,

[0142] The difference is less than the switching threshold, so the antenna corresponding to Tx does not perform uplink antenna diversity switching. If the uplink performance index compensation value is added, the receiving antenna signal strength value received by the modem will be adjusted to:

[0143] rx0(ANT4)=-100-(0)=-100dBm, rx1(ANT3)=-98-(-1.5)=-96.5dBm,

[0144] rx2(ANT2)=-101-(-0.8)=-100.2dBm, rx3(ANT0)=-102-(0.9)=-102.9dBm

[0145] Since rx1(ANT3)-rx0(ANT4)=(-96.5)-(-100)=3.5dB, which is greater than the switching threshold, Tx performs uplink antenna diversity switching, and the antenna corresponding to Tx is switched from ANT4 to ANT3.

[0146] In one scenario, taking the gesture grip as a closed left hand grip, the current uplink frequency point of the communication service is EARFCN=19575dB, and the downlink frequency point is EARFCN=1575dB as an example, the lower gesture grip position of the antenna corresponding to Tx on ANT4 in Table 3 is used as the compensation value for explanation.

[0147] The switching threshold may be 3dB.

[0148] The antenna corresponding to the current Tx is ANT3, and the signal strength values ​​of each receiving antenna received by the modem are:

[0149] rx0(ANT3)=-90dBm, rx1(ANT2)=-89dBm,

[0150] rx2(ANT4)=-88dBm, rx3(ANT0)=-92dBm

[0151] If the row performance index compensation value is not added, due to

[0152] Rx1(ANT2)-rx0(ANT3)=(-89)-(-90)=1dB,

[0153] rx2(ANT4)-rx0(ANT3)=(-88)-(-90)=2dB,

[0154] rx3(ANT0)-rx0(ANT3)=(-92)-(-90)=-2dB,

[0155] The difference is less than the switching threshold, so the antenna corresponding to Tx does not perform uplink antenna diversity switching. If the uplink performance index compensation value is added, the receiving antenna signal strength value received by the modem will be adjusted to:

[0156] rx0(ANT3)=-90-(0)=-90dBm, rx1(ANT2)=-89-(0.5)=-89.5dBm,

[0157] rx2(ANT4)=-88-(-1.3)=-86.7dBm, rx3(ANT0)=-92-(1.5)=-93.5dBm

[0158] Since rx1(ANT4)-rx0(ANT3)=(-86.7)-(-90)=3.3dB, which is greater than the switching threshold, the antenna corresponding to Tx performs uplink antenna diversity switching, and the antenna corresponding to Tx is switched from ANT3 to ANT4.

[0159] In the disclosed embodiment, the uplink performance index compensation value and the downlink performance index compensation value of the main set receiving antenna switching to the diversity receiving antenna are calculated in advance based on the antenna performance index of the hand gesture grip being a closed left hand grip, the uplink frequency being EARFCN=19575dB, and the downlink frequency being EARFCN=1575dB. After the terminal recognizes that the current hand gesture grip is a closed left hand grip, the current uplink frequency of the communication service is EARFCN=19575dB, and the downlink frequency is EARFCN=1575dB, it retrieves the corresponding uplink performance index compensation value and downlink performance index compensation value, and selects the uplink performance index compensation value or the downlink performance index compensation value as the compensation value of the antenna received signal strength value according to the current communication service scenario, and performs uplink antenna diversity switching based on the compensated antenna received signal strength value.

[0160] In the disclosed embodiment, the antenna received signal strength value after compensation can better reflect the performance of the antenna, so that when uplink antenna diversity switching is performed based on the compensated antenna received signal strength value, it can be more accurately switched to an antenna with good performance.

[0161] Among them, using the uplink performance index compensation value as the compensation value of the antenna received signal strength value can increase the probability of the antenna switching to an antenna with a good uplink performance index, thereby improving the antenna's transmission performance.

[0162] Among them, using the downlink performance index compensation value as the compensation value of the antenna received signal strength value can increase the probability of the antenna switching to an antenna with a good downlink performance index, thereby improving the service throughput of the downlink antenna.

[0163] Based on the same concept, an embodiment of the present disclosure also provides an uplink antenna diversity switching device.

[0164] It is understandable that in order to realize the above functions, the uplink antenna diversity switching device provided in the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0166] The identification unit 101 is used to identify the current hand gesture of the terminal, the current communication service scenario of the terminal, and the current frequency band of the terminal for performing the communication service.

[0167] The switching unit 102 is used to determine the antenna received signal strength value for antenna diversity switching based on the current hand gesture, the current communication service scenario and the current frequency band, and perform uplink antenna diversity switching according to the antenna received signal strength value.

[0168] In one embodiment, the switching unit 102 determines the antenna received signal strength value for antenna diversity switching based on the current hand gesture grip, the current communication service scenario, and the current frequency band, and performs uplink antenna diversity switching according to the antenna received signal strength value: based on the correspondence between the frequency band, hand gesture grip, and the compensation value, determine the compensation value corresponding to the current frequency band and the current hand gesture grip. Based on the compensation value and the current communication service scenario, the antenna received signal strength value is compensated, and the transmit antenna diversity switching is performed based on the compensated antenna received signal strength value.

[0169] In one embodiment, the compensation value includes an uplink performance index compensation value and a downlink performance index compensation value. The switching unit 102 compensates the antenna received signal strength value based on the compensation value and the current communication service scenario in the following manner: in response to the current communication service scenario being a target communication service scenario, determining that the compensation value that matches the current communication service scenario is the downlink performance index compensation value. Or in response to the current communication service scenario being a non-target communication service scenario, determining that the compensation value that matches the current communication service scenario is the uplink performance index compensation value. The target communication service scenario is a communication scenario in which the amount of downlink service data is greater than the amount of uplink service data. The antenna received signal strength value is compensated according to the compensation value that matches the current communication service scenario.

[0170] In one implementation, the downlink performance indicator compensation value is determined based on the total omnidirectional sensitivity of the antenna. The uplink performance indicator compensation value is determined based on the total radiated power of the antenna.

[0171] In one embodiment, the current communication service scenario is determined to be a target communication service scenario in response to at least one of the following being satisfied: the current throughput is greater than a preset throughput threshold; the signal-to-noise ratio is greater than zero, and the signal strength value is greater than a preset signal strength threshold; the block error rate is greater than a preset block error rate threshold.
