[0001] The present application relates to the field of communication technology, and in particular to a method for determining an uplink margin value and a related device. Background Art

[0002] Non-terrestrial network communications are characterized by low latency and low cost. Combining them with smartphone applications can realize voice call services, filling the gap in smartphone communication services in areas not covered by ground base stations such as deserts and seas, and effectively solving the problem of smartphones being unable to communicate in areas not covered by ground base stations.

[0003] The link distance of non-terrestrial network communications will change at any time during the movement process, which will cause a large change in the link space loss. Therefore, power control measures are needed for smartphones to ensure that the power of smartphone signals reaching the receiving point of non-terrestrial network nodes is basically constant. Currently, power control can be achieved based on the link margin value, where the link margin value indicates the power loss range that the signal can withstand when it is transmitted in the link.

[0004] In the prior art, when obtaining a link margin value, the link margin value is usually determined based on a quality indicator and a target signal quality.

[0092] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0093] Some of the terms used in the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.

[0094] Access channel: also known as the control channel, which transmits control-related information.

[0095] Automatic gain control (AGC): An automatic control method that automatically adjusts the gain of an amplifier circuit according to the signal strength.

[0096] Sliding average: Calculate the moving average by adding and subtracting new and old data in sequence from period to period, so as to eliminate accidental changes and find out the development trend of things.

[0097] Open-loop power control: does not require feedback from the receiver and performs power control based on its own measurements.

[0098] Closed-loop power control: The transmitter controls the transmission power based on the feedback information sent by the receiver.

[0099] The following is a brief introduction to the design concept of the embodiment of the present application:

[0100] For mobile communication services, due to traditional communication methods, smartphones can only communicate within the coverage area of ​​ground base stations. Therefore, there is a problem that smartphones cannot communicate in areas not covered by ground base stations, such as deserts and sea areas.

[0101] Non-terrestrial network communications are characterized by low latency and low cost. Combining them with smartphone applications can realize voice call services, filling the gap in smartphone communication services in areas not covered by ground base stations, and effectively solving the problem of smartphones being unable to communicate in areas not covered by ground base stations.

[0102] The link distance of non-terrestrial network communication will change at any time during the mobile process, which will cause a large change in the link space loss. Therefore, it is necessary to take power control measures for smartphones to ensure that the power of smartphone signals reaching the non-terrestrial network node is basically constant. In related technologies, power control technology is a key technology to ensure the normal operation of the system, improve system capacity, and reduce harmful interference to other systems. Effective power control technology needs to minimize the transmission power of terminals and non-terrestrial network nodes while ensuring the quality of user communications, so as to reduce system interference, increase system margin, and extend the battery life of terminals and non-terrestrial network nodes.

[0103] Currently, power control can be implemented based on a link margin value, where the link margin value represents a power loss range that a signal can withstand when transmitting in a link.

[0104] In the prior art, when obtaining a link margin value, the link margin value is usually determined based on a quality indicator and a target signal quality.

[0105] However, there are multiple channels between the terminal and the non-ground network node, and there are differences between each channel. If only the quality indication and the target signal quality are considered for all channels, the link margin value will be inaccurate, and the link power control cannot be effectively performed, making the link quality unable to meet the requirements.

[0106] Based on the above problems, in an embodiment of the present application, a method for determining an uplink margin value and a related device are proposed. The transmitting end determines the quality indication of the downlink signal based on at least the strength indication information and the quality error information of the downlink signal, and then adopts a corresponding determination method according to different uplink channel types, at least based on the quality indication, to determine the corresponding uplink margin value. In this way, based on the channel function characteristics of the uplink channel, different margin value determination methods are adopted for different uplink channel types, so that the link margin values ​​of each type of uplink channel can be accurately measured, thereby achieving effective and accurate control of power.

[0107] The preferred implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0108] like Figure 1 As shown, it is a schematic diagram of an application scenario of an embodiment of the present application. The application scenario diagram includes a non-ground network node 110 and a terminal 120. The non-ground network node 110 and the terminal 120 are connected via a communication link. It should be noted that there is no limit on the number of non-ground network nodes 110 and terminals 120. The above system architecture is only an example of a system architecture applicable to an embodiment of the present invention. The system architecture applicable to the embodiment of the present invention is compared Figure 1 The system architecture shown may also add other entities, or reduce some entities, which will not be described in detail here.

[0109] The terminal 120 includes but is not limited to mobile phones, tablet computers, laptop computers, desktop computers, e-book readers, intelligent voice interaction devices, smart home appliances, vehicle-mounted terminals, etc. The non-ground network nodes 110 include but are not limited to communication nodes such as satellites, space stations, drones, and high-altitude platforms.

[0110] In an embodiment of the present application, the transmitting end is a terminal and the receiving end is a non-ground network node, or the transmitting end is a non-ground network node and the receiving end is a terminal, and this is not limited in the embodiment of the present application.

[0111] Based on the above embodiments, the following embodiments take the sending end as a terminal as an example. Figure 2 FIG. 1 is a schematic diagram of a first flow chart of a method for determining an uplink margin value in an embodiment of the present application, which specifically includes:

[0112] Step 20: Determine a quality indicator of the downlink signal based at least on the strength indicator information and the quality error information of the downlink signal.

[0113] The downlink signal includes: one or more short burst signals.

[0114] In an embodiment of the present application, after the terminal receives the downlink signal sent by the non-ground network node, it determines the strength indication information and quality error information of the downlink signal, and determines the quality indication of the downlink signal based on the strength indication information and quality error information of the downlink signal.

[0115] In addition, it is worth noting that, in the embodiment of the present application, before determining the strength indication information and quality error information of the downlink signal, it is necessary to perform frequency offset calibration on the downlink signal.

[0116] In the embodiment of the present application, a downlink signal is acquired, a fixed frequency offset is eliminated for each received signal level included in the downlink signal, and a downlink signal after frequency offset calibration is obtained.

[0117] In this way, since the downlink signal has a frequency deviation, the frequency deviation will affect the quality indication. Therefore, the frequency deviation of the downlink signal is calibrated first to make the calculation of the quality indication more accurate.

[0118] Specifically, when determining the strength indication information and quality error information of the short burst, the following operations are specifically performed: Figure 3 As shown, it is a schematic diagram of the process of determining the intensity indication information and the quality error information in the embodiment of the present application. Figure 3 , and explain in detail the specific operations performed:

[0119] Step 30: Determine strength indication information based on the levels of each received signal contained in the downlink signal and the signal gain corresponding to the downlink signal.

[0120] The strength indication information may be a received signal strength indication (RSSI), which is not limited in the embodiments of the present application.

[0121] In the embodiment of the present application, the product of the average value of each received signal level and the signal gain is calculated to obtain the strength indication information of the downlink signal.

[0122] The downlink signal strength indication information in the embodiment of the present application may be expressed as:

[0123]

[0124] Wherein, AGC is the signal gain corresponding to the downlink signal, the signal gain is introduced by the automatic gain controller, N is the number of received signal levels corresponding to the downlink signal, and μ(n) is the average function of each received signal level in the downlink signal.

[0125] In this way, the fixed frequency offset is eliminated, and all time-varying processes affecting the estimation process are compensated, such as automatically controlling the gain, to obtain relative measurements, so that reliable and accurate strength indication information can be obtained.

[0126] Step 31: Determine quality error information based on each received signal level and an ideal signal level corresponding to each received signal level.

[0127] The ideal signal level is determined based on the modulation type of the corresponding received signal level.

[0128] The quality error information may be error vector magnitude (EVM), which is not limited in the embodiments of the present application.

[0129] In an embodiment of the present application, the ideal signal level corresponding to each received signal level is determined based on the modulation type of each received signal level, and then the quality error information of the downlink signal is calculated based on the average value of each received signal level and the variance value between each received signal level and the corresponding ideal signal level.

[0130] The quality error information of the downlink signal in the embodiment of the present application can be expressed as:

[0131]

[0132] Wherein, δ(n) is the variance value between each received signal level and the corresponding ideal signal level in the downlink signal, and μ(n) is the average function of each received signal level in the downlink signal.

[0133] For example, assuming that the receiving signal levels are respectively receiving signal level S1, receiving signal level S2, and receiving signal level S3, the modulation type corresponding to receiving signal level S1 is B1, the modulation type corresponding to receiving signal level S2 is B2, the modulation type corresponding to receiving signal level S3 is B2, the ideal signal level corresponding to modulation type B1 is ST1, and the ideal signal level corresponding to modulation type B2 is ST2, then the ideal signal level corresponding to receiving signal level S1 is ST1, the ideal signal level corresponding to receiving signal level S2 is ST2, and the ideal signal level corresponding to receiving signal level S3 is ST2.

[0134] Specifically, when determining the quality indicator of the downlink signal, the following operations are performed: Figure 4As shown, it is a schematic diagram of the process of determining the quality indication in the embodiment of the present application. Figure 4 , and explain in detail the specific operations performed:

[0135] Step 200: Determine a first initial received signal quality of a downlink signal based on the strength indication information and a first nonlinear function, and determine a second initial received signal quality of the downlink signal based on the quality error information and a second nonlinear function.

[0136] In the embodiment of the present application, the first initial received signal quality of the downlink signal can be expressed as:

[0137] SQI1=f1{RSSI}

[0138] The second initial received signal quality of the downlink signal can be expressed as:

[0139] SQI2=f2{EVM}

[0140] Among them, f1{*} is a nonlinear function of strength indication information, f2{*} is a nonlinear function of quality error information, f1{*} and f2{*} are different, RSSI is the strength indication information of the downlink signal, and EVM is the quality error information of the downlink signal.

[0141] Step 201: determine whether the difference between the first initial received signal quality and the second initial received signal quality is less than a preset difference threshold, if so, execute step 202, otherwise, execute step 203.

[0142] In an embodiment of the present application, the difference between the first initial received signal quality and the second initial received signal quality is calculated, and the absolute value of the difference is taken to obtain an updated difference, and it is determined whether the updated difference is less than a preset difference threshold.

[0143] Among them, the preset difference threshold can be 0.5dB, which is not limited in the embodiments of the present application.

[0144] Step 202: Determine a quality indicator of a downlink signal based on the first initial received signal quality and the second initial received signal quality.

[0145] In an embodiment of the present application, if the difference between the first initial received signal quality and the second initial received signal quality is less than a preset difference threshold, the average of the first initial received signal quality and the second initial received signal quality is calculated to obtain a quality indication of the downlink signal.

[0146] The quality indicator of the downlink signal in the embodiment of the present application can be expressed as:

[0147]

[0148] For example, see Figure 5 As shown, it is a schematic diagram of measuring quality indication in an embodiment of the present application. Assuming that the preset difference threshold is 0.5dB, the first initial received signal quality of the downlink signal A is 80.1dB, and the second initial received signal quality is 80.2dB, then the difference between the first initial received signal quality and the second initial received signal quality is abs(80.1-80.2)=0.1, the difference between the first initial received signal quality and the second initial received signal quality 0.1dB is less than the difference threshold 0.5dB, and the quality indication of the downlink signal A is (80.1+80.2) / 2=80.15.

[0149] Step 203: Determine that the quality indicator of the downlink signal is invalid.

[0150] In the embodiment of the present application, if the difference between the first initial received signal quality and the second initial received signal quality is not less than a preset difference threshold, the quality indication of the downlink signal is determined to be invalid, and the quality indication of the next downlink signal is measured.

[0151] For example, Figure 5 As shown, assuming that the first initial received signal quality of the downlink signal B is 81dB and the second initial received signal quality is 82dB, the difference between the first initial received signal quality and the second initial received signal quality is abs(81-82)=1, the difference of 1dB between the first initial received signal quality and the second initial received signal quality is greater than the difference threshold of 0.5dB, the quality indication of the downlink signal B is invalid, and the quality indication of the downlink signal C is measured.

[0152] In this way, by comparing the first initial received signal quality and the second initial received signal quality, the validity of the first initial received signal quality and the second initial received signal quality is determined, thereby improving the reliability of the quality indication.

[0153] Step 21: According to different uplink channel types, at least based on the quality indication, a corresponding determination method is adopted to determine a corresponding uplink margin value.

[0154] The uplink channel type is an access channel or a service channel.

[0155] In the embodiment of the present application, the channel type of the uplink channel is determined. When the uplink channel type is an access channel, the first determination method corresponding to the access channel is adopted to determine the uplink margin value of the uplink channel based on the quality indication of the downlink signal. When the uplink channel type is a service channel, the second determination method corresponding to the service channel is adopted to determine the uplink margin value of the uplink channel based on the quality indication of the downlink signal.

[0156] Specifically, when determining the uplink margin value, the following operations are performed: Figure 6 As shown, it is a schematic diagram of the process of determining the uplink margin value in an embodiment of the present application. Figure 6 , and explain in detail the specific operations performed:

[0157] Step 210: Determine whether the uplink channel type is an access channel, if so, execute step 211, otherwise, execute step 212.

[0158] In the embodiment of the present application, if the terminal is ready to access, the uplink channel type is determined to be an access channel; if the terminal is ready to transmit service-related information, the uplink channel type is determined to be a service channel.

[0159] Step 211: Determine an uplink margin value based on the quality indicator, a preset first target signal quality and a first margin deviation.

[0160] The first margin deviation represents: a transmission power level difference between a signal of an access channel and a signal of a service channel.

[0161] In an embodiment of the present application, it is determined whether the uplink channel type is an access channel. When the uplink channel type is an access channel, the following operations are performed for each short burst in each short burst: the difference between the quality indication of the downlink signal and the preset first target signal quality is calculated, and then the difference and the first margin deviation are summed to determine the uplink link margin value corresponding to the downlink signal.

[0162] For example, see Figure 7 As shown, it is a schematic diagram of obtaining the uplink margin value in an embodiment of the present application. Assuming that the uplink channel is channel 1 and the uplink channel type of channel 1 is an access channel, the uplink margin value of channel 1 is determined based on the quality indication of the downlink signal, the preset first target signal quality and the first margin deviation.

[0163] Among them, the uplink margin value corresponding to the access channel type in the embodiment of the present application can be expressed as:

[0164] LQI1=SQI-SQT1+Power_advantage

[0165] Among them, SQT1 is a preset first target signal quality, Power_advantage is a first margin deviation, and SQI is a quality indicator of a downlink signal.

[0166] In this way, the access channel obtains the uplink margin value based on the quality indication of the downlink signal, the preset first target signal quality and the first margin deviation. Combined with the first margin deviation, the accuracy of the access channel link margin value can be improved, and the open-loop power control of the uplink access channel signal can be effectively realized.

[0167] Step 212: Determine an uplink margin value based on the quality indicator, the second margin deviation and a preset second target signal quality.

[0168] The second margin deviation represents: a difference between a reference transmission power and an actual transmission power at the receiving end.

[0169] For example, Figure 7 As shown, assuming that the uplink channel is channel 2 and the channel type of channel 2 is a service channel, the uplink margin value of channel 2 is determined based on the quality indication of the downlink signal.

[0170] Specifically, when executing step 212, the following operations are performed: Figure 8 As shown, it is a schematic diagram of the process of determining the uplink margin value of the service channel in an embodiment of the present application. Figure 8 , and explain in detail the specific operations performed:

[0171] Step 2120: Determine a target average quality indicator of the downlink signal based on the quality indicator of each short burst signal included in the downlink signal.

[0172] The downlink signal includes a preset number of short burst signals.

[0173] In the embodiment of the present application, the short burst signals are sorted in chronological order, and the sorted short burst signals are grouped according to a preset number to obtain downlink signals.

[0174] For example, assuming that the short burst signals are sorted in chronological order as follows: short burst signal 1, short burst signal 2, short burst signal 3, short burst signal 4, short burst signal 5, short burst signal 6, short burst signal 7, short burst signal 8, short burst signal 9, short burst signal 10, short burst signal 11, short burst signal 12, short burst signal 13, short burst signal 14, short burst signal 15, and the preset number is 5, then short burst signal 1, short burst signal 2, short burst signal 3, short burst signal 4, short burst signal 5 are taken as a downlink signal, short burst signal 6, short burst signal 7, short burst signal 8, short burst signal 9, short burst signal 10 are taken as a downlink signal, and short burst signal 11, short burst signal 12, short burst signal 13, short burst signal 14, short burst signal 15 are taken as a downlink signal.

[0175] Specifically, when executing step 2120, the following operations are performed: Fig. 9 As shown, it is a schematic diagram of the process of determining the target average quality indicator in the embodiment of the present application. Fig. 9 , and explain in detail the specific operations performed:

[0176] Step 2120-1: Determine an initial average quality indicator and an initial quality indicator variance of the downlink signal based on the quality indicator of each short burst signal.

[0177] In the embodiment of the present application, based on the quality indication of each short burst signal included in the downlink signal, an initial average quality indication of the downlink signal is determined, and based on the quality indication of each short burst signal included in the downlink signal and the initial average quality indication, an initial quality indication variance of the downlink signal is determined.

[0178] Among them, the initial average received signal quality of the downlink signal in the embodiment of the present application can be expressed as:

[0179]

[0180] Among them, SQI j is the quality indicator of the j-th short burst signal among the short burst signals included in the downlink signal, and M is the number of the short burst signals included in the downlink signal.

[0181] The initial received signal quality variance of the downlink signal in the embodiment of the present application can be expressed as:

[0182]

[0183] For example, assuming that the quality indicators of the short burst signals included in the downlink signal A are 80, 81, 82, 83, and 84 respectively, the initial average received signal quality of the downlink signal A is (80+81+82+83+84) / 5=82, and the initial received signal quality variance of the downlink signal A is ((-2) 2 +(-1) 2 +(0) 2 +(1) 2 +(2) 2 ) / 5=2.

[0184] Step 2120-2: Adjust the initial quality indication variance of the downlink signal to obtain the target quality indication variance of the downlink signal.

[0185] Specifically, when adjusting the initial quality indication variance of the downlink signal to obtain the target quality indication variance of the downlink signal, the following operations are specifically performed: Fig.10 As shown, it is a schematic diagram of the process of determining the target quality indicator variance in the embodiment of the present application. Fig.10Detailed description of the specific operations performed:

[0186] Step 2120-2-1: Determine whether the downlink signal is an initial downlink signal, if so, execute step 2120-2-2, otherwise, execute step 2120-2-3.

[0187] Among them, the initial downlink signal is the earliest downlink signal.

[0188] For example, assuming that after the short burst signals are sorted and grouped in time order, the obtained downlink signals include downlink signal A, downlink signal B and downlink signal C, and the time order of the downlink signals is downlink signal A, downlink signal B and downlink signal C, then downlink signal A is the initial downlink signal.

[0189] Step 2120-2-2: Use the initial quality indication variance of the downlink signal as the target quality indication variance of the downlink signal.

[0190] In the embodiment of the present application, it is determined whether the downlink signal is an initial downlink signal. If the downlink signal is an initial downlink signal, the target quality indication variance of the downlink signal is the initial quality indication variance of the downlink signal.

[0191] The target quality indicator variance of the initial downlink signal in the embodiment of the present application can be expressed as:

[0192] δ 2 {SQI1}=δ 2 {SQI01}

[0193] Among them, δ 2 {SQI01} is the initial quality indicator variance of the initial downlink signal.

[0194] Step 2120-2-3: Obtain the target filter coefficient, and adjust the initial quality indication variance of the downlink signal based on the target filter coefficient and the target quality indication variance of the initial downlink signal to obtain the target quality indication variance of the downlink signal.

[0195] In an embodiment of the present application, it is determined whether the downlink signal is an initial downlink signal. If the downlink signal is not an initial downlink signal, a target filter coefficient is obtained, and the target filter coefficient and a target quality indication variance of the initial downlink signal are used to adjust the initial quality indication variance of the downlink signal to obtain a target quality indication variance of the downlink signal.

[0196] The target quality indicator variance of the kth downlink signal in the embodiment of the present application can be expressed as:

[0197] δ 2 {SQI k}=flr·(δ 2 {SQI0k})+(1+flr)·(δ 2 {SQI1})

[0198] Among them, δ 2 {SQI0 k} is the initial quality indicator variance of the kth downlink signal, δ 2 {SQI1} is the target quality indication variance of the initial downlink signal, k is an integer greater than 1, flr is the target filter coefficient, and the target filter coefficient can be a first-order filter coefficient, which is not limited in the embodiments of the present application.

[0199] Specifically, when obtaining the target filter coefficient, the following operations are performed: Fig.11 As shown, it is a schematic diagram of the process of obtaining the target filter coefficient in the embodiment of the present application. Fig.11 Detailed description of the specific operations performed:

[0200] Step 2120-2-3-1: Determine whether the initial quality indication variance of the downlink signal is less than the target quality indication variance of the initial downlink signal. If so, execute step 2120-2-3-2; otherwise, execute step 2120-2-3-3.

[0201] Step 2120-2-3-2: Use the first preset filter coefficient as the target filter coefficient.

[0202] The first preset filter coefficient represents: reducing power.

[0203] In the embodiment of the present application, it is determined whether the initial quality indication variance of the downlink signal is less than the target quality indication variance of the initial downlink signal. If the initial quality indication variance of the downlink signal is less than the target quality indication variance of the initial downlink signal, the first preset filter coefficient is used as the target filter coefficient.

[0204] For example, assuming that the initial received signal quality variance of downlink signal B is 4, the target quality indication variance of the initial downlink signal is 6, the initial quality indication variance of downlink signal B is less than the target quality indication variance of the initial downlink signal, and the target filter coefficient corresponding to downlink signal B is the first preset filter coefficient h_down.

[0205] Step 2120-2-3-3: Use the second preset filter coefficient as the target filter coefficient.

[0206] The second preset filter coefficient represents: increasing power.

[0207] In the embodiment of the present application, it is determined whether the initial quality indication variance of the downlink signal is less than the target quality indication variance of the initial downlink signal. If the initial quality indication variance of the downlink signal is not less than the target quality indication variance of the initial downlink signal, the second preset filter coefficient is used as the target filter coefficient.

[0208] For example, assuming that the initial quality indication variance of the downlink signal C is 8, the target quality indication variance of the initial downlink signal is 6, the initial quality indication variance of the downlink signal C is greater than the target quality indication variance of the initial downlink signal, and the target filter coefficient corresponding to the downlink signal C is the second preset filter coefficient h_up.

[0209] Step 2120-3: based on the target quality indication variance of the downlink signal and the preset sliding average coefficient, the initial average quality indication of the downlink signal is updated to obtain the target average quality indication of the downlink signal.

[0210] In the embodiment of the present application, the product of the target quality indication variance of the downlink signal and the preset sliding average coefficient is calculated, and then the difference between the initial average quality indication of the downlink signal and the product is calculated to obtain the target average quality indication of the downlink signal.

[0211] The target average quality indicator of the downlink signal in the embodiment of the present application can be expressed as:

[0212]

[0213] in, is the initial average quality indicator of the downlink signal, β is the preset sliding average coefficient, δ 2 {SQI} is the target quality indicator variance of the downlink signal.

[0214] Step 2121: Receive the second margin deviation sent by the receiving end.

[0215] In an embodiment of the present application, the terminal receives a second margin deviation corresponding to a downlink signal represented in binary and sent by a non-ground network node, decodes the second margin deviation corresponding to the downlink signal represented in binary, and obtains a second margin deviation represented in decimal.

[0216] Step 2122: Determine an uplink margin value based on the target average quality indication and the second margin deviation, and the second target signal quality.

[0217] In the embodiment of the present application, the difference between the target average quality indicator of the downlink signal and the second target signal quality is calculated, and then the difference and the second margin deviation are summed to obtain the uplink margin value corresponding to the downlink signal.

[0218] Among them, the uplink margin value corresponding to the service channel type in the embodiment of the present application can be expressed as:

[0219]

[0220] Among them, PT is the second margin deviation corresponding to the downlink signal, is the target average quality indicator of the downlink signal, and SQT2 is the preset second target signal quality.

[0221] In this way, since a short burst signal is very short and has randomness, the quality indication of the downlink signal takes into account the target average quality indication of multiple short burst signals, which can improve the accuracy of the uplink margin value. In addition, the service channel obtains the difference between the reference transmission power and the actual transmission power of the receiving end under the corresponding downlink signal by parsing multiple time slots, that is, the second margin deviation. Combining the second margin deviation, the target average quality indication and the second target signal quality, the uplink margin value can flexibly and accurately realize the closed-loop power control of the service channel signal.

[0222] Further, after the uplink margin value is obtained, power control is performed according to the uplink margin value.

[0223] Based on the above embodiments, see Fig.12 FIG. 1 is a second flow chart of a method for determining an uplink margin value in an embodiment of the present application, which specifically includes:

[0224] Step 1201: Determine a quality indicator of a downlink signal based at least on the strength indicator information and the quality error information of the downlink signal.

[0225] Step 1202: Determine whether the uplink channel type is an access channel, if so, execute step 1203, otherwise, execute step 1204.

[0226] Step 1203: Determine an uplink margin value based on the quality indication, a preset first target signal quality and a first margin deviation.

[0227] The first margin deviation represents: a transmission power level difference between a signal of an access channel and a signal of a service channel.

[0228] Step 1204: Determine a target average quality indicator of the downlink signal based on the quality indicator of each short burst signal included in the downlink signal.

[0229] Step 1205: Receive the second margin deviation sent by the receiving end.

[0230] The second margin deviation represents: a difference between a reference transmission power and an actual transmission power at the receiving end.

[0231] Step 1206: Determine an uplink margin value based on the target average quality indicator and the second margin deviation, and the second target signal quality.
