[0033] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0034] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms thereof, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open, inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0036] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0037] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0038] In the existing communication standardization protocols, the wireless channel model takes far-field plane waves and communication between two devices as the basic assumptions, and the corresponding channel codebook and channel information feedback mechanism are designed based on this. The existing channel information acquisition and feedback methods can be as follows Figure 1 As shown, see Figure 1, the terminal receives channel measurement reference signals sent by different ports (different ports may correspond to different base stations, or different antenna array panels on the same base station, or different array element ports on the same antenna array panel). For example, the terminal receives channel measurement reference signal 1 sent by port 1 and channel measurement reference signal 2 sent by port 2, so as to obtain the channel information corresponding to each channel measurement reference signal and the indication information corresponding to the channel information, and then feeds back the indication information of the channel information in a certain pre-agreed manner (such as agreeing on the same codebook and the same feedback mode). In this way, on the one hand, the channel information is related to a specific angle information, and on the other hand, for different channel measurement reference signals, the terminal independently executes a channel information acquisition and feedback process without considering the possible correlation between the channel information (or indication information) and other channel information (or indication information). For example, continue to refer to Figure 1 , indication information 1 is only obtained by channel measurement reference signal 1, and has nothing to do with channel measurement reference signal 2 or indication information 2, that is, indication information 1 is determined by channel measurement reference signal 1, and indication information 2 is determined by channel measurement reference signal 2, and channel measurement reference signal 1 and channel measurement reference signal 2 are not related. In this way, the processing complexity of obtaining channel information is high, and in collaborative processing, if the existing channel information acquisition and feedback mechanism is used, due to the high processing complexity of obtaining channel information, the obtained channel information cannot well reflect the channel state corresponding to certain distributed scenarios, that is, information deviation is generated, thereby affecting the performance of the communication system.

[0039] Based on this, how to reduce the processing complexity of acquiring channel information is a technical problem that needs to be solved urgently.

[0040] Based on this, the embodiments of the present disclosure provide a method, device and storage medium for obtaining channel information. After obtaining first indication information corresponding to the first channel information based on measurement of a first channel measurement reference signal, second indication information corresponding to the second channel information can be obtained based on the relationship between the first indication information and the second indication information indicated by the first configuration information and the first indication information, that is, the independent first indication information and the second indication information are associated, and the second indication information can be obtained based on the first indication information and the first configuration information, which reduces the processing complexity of obtaining channel information and helps to improve the performance of the communication system.

[0041] The following describes the solutions of the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0042] The technical solution provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, new radio (NR) mobile communication networks using fifth generation mobile communication technology (5th generation mobile networks, 5G), future mobile communication networks or multiple communication convergence systems, etc., and the embodiments of the present disclosure are not limited to this.

[0043] Figure 2 FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the communication system includes but is not limited to a terminal 110 and a base station 120. The terminal 110 and the base station 120 can send, receive and perform related interactions with wireless signals.

[0044] In a wireless communication scenario, the terminal 110 communicates with the base station 120 through a wireless channel.

[0045] The terminal 110 may be a device with wireless transceiver functions, such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The embodiments of the present disclosure do not limit the specific types of terminals.

[0046] The base station 120 may be any of an evolution node B (eNB), a next generation node B (gNB), a transmission receive point (TRP), a transmission point (TP), and some other access nodes. According to the size of the service coverage area provided, the base station can be divided into a macro base station for providing macro cells, a micro base station for providing pico cells, and a femto base station for providing femto cells. With the continuous evolution of wireless communication technology, future base stations may also adopt other names.

[0047] It should be understood that Figure 2 is an exemplary structural diagram, Figure 2 The number of devices included in the communication system shown is not limited, for example, the number of base stations and terminals is not limited. Figure 2 In addition to the equipment shown, Figure 2 The communication system shown may also include other devices, which is not limited thereto.

[0048] Next, if Figure 3 As shown, the embodiment of the present disclosure provides a method for obtaining channel information, which is applied to a terminal, and the terminal may be the above Figure 2 The terminal 110, the method comprises the following steps:

[0049] S101. Obtain first indication information corresponding to first channel information based on measurement of a first channel measurement reference signal.

[0050] In some embodiments, when the terminal receives a first channel measurement reference signal sent by the network side, the terminal measures the first channel measurement reference signal to obtain first channel information and first indication information corresponding to the first channel information. The network side may be a base station.

[0051] In some embodiments, the first channel information is channel state information.

[0052] In some embodiments, the first indication information is precoding matrix indication information.

[0053] S102: Obtain second indication information corresponding to the second channel information based on the first indication information and the first configuration information.

[0054] In some embodiments, after obtaining the first indication information, the terminal may obtain the second indication information corresponding to the second channel information based on the first indication information and the first configuration information. The first configuration information is used to configure the relationship between the first indication information and the second indication information. The first configuration information is pre-configured or configured on the network side, and the network side may be a base station.

[0055] As an example, the first configuration information includes a first parameter and a first function, wherein the first parameter is used to characterize the interval between the first indication information and the second indication information, and the interval is an integer, that is, the interval can be a positive integer or a negative integer.

[0056] It should be understood that when the spacing is a positive integer, it means that the first indication information is located on the left side of the second indication information, and when the spacing is a negative integer, it means that the first indication information is located on the right side of the second indication information.

[0057] In some embodiments, the distance between the first indication information and the second indication information may be an average distance between the first indication information and the second indication information.

[0058] In some embodiments, the first function is used to constrain the value of the second indication information to be within a first value range, wherein the first value range may be preconfigured or included in the first configuration information.

[0059] As a possible example, the first function is specifically used to: when the first value is within the first value range, determine the value of the second indication information to be the first value. When the first value is greater than the upper limit of the first value range, determine the value of the second indication information to be the upper limit of the first value range. When the first value is less than the lower limit of the first value range, determine the value of the second indication information to be the lower limit of the first value range. The first value is determined according to the value of the first indication information and the first parameter.

[0060] As an example, the first value is the sum of the value of the first indication information and the first parameter. The first value may also be the difference between the value of the first indication information and the first parameter, the quotient of the value of the first indication information and the first parameter, the product of the value of the first indication information and the first parameter, etc. The embodiment of the present disclosure does not limit the specific setting of the first value.

[0061] Exemplarily, based on the first indication information and based on the first configuration information, second indication information corresponding to the second channel information is obtained, which may be shown in the following formula (1) or formula (2):

[0062]

[0063]

[0064] In the above formula (1) and formula (2), i1 is the first indication information, i2 is the second indication information, is the first function, Δi 1,2 1 is the first parameter, i min is the lower limit of the first value range, i max is the upper limit of the first value range.

[0065] It can be seen from the above formula (1) and formula (2) that, based on the constraint of the first function, the value of the second indication information is within the first value range.

[0066] In some embodiments, the value of the first indication information is within the first value range, that is, the value of the first indication information and the value of the second indication information may both be within the first value range.

[0067] As a possible example, the second indication information may be an indication information group, which includes multiple indication information. That is, the indication information group may be determined based on the first indication information and the first configuration information, and the indication information group includes multiple indication information corresponding to multiple channel information, thereby reducing the processing complexity of obtaining the channel information.

[0068] based on Figure 3 In the embodiment shown, after obtaining the first indication information corresponding to the first channel information based on the measurement of the first channel measurement reference signal, the second indication information corresponding to the second channel information can be obtained based on the relationship between the first indication information and the second indication information indicated by the first configuration information and the first indication information. That is, there is no need to measure the second channel measurement reference signal, and the second indication information corresponding to the second channel measurement reference signal can be obtained based on the relationship between the first indication information and the second indication information. The independent first indication information and the second indication information are associated, which reduces the processing complexity of obtaining the channel information, helps to reduce the overhead of subsequent feedback indication information, and improves the performance of the communication system.

[0069] The above embodiment is described by taking the example of obtaining the second indication information corresponding to the second channel measurement reference signal without measuring the second channel measurement reference signal. In some embodiments, for example Figure 4 As shown, the above step S102 can also be implemented as the following steps:

[0070] S201. Determine, based on first indication information and first configuration information, a second value range corresponding to second indication information from a first value range.

[0071] In some embodiments, after obtaining the first indication information, in order to quickly obtain the second indication information and reduce the processing complexity of obtaining the channel information, the terminal may determine the second value range corresponding to the second indication information from the first value range based on the first indication information and the first configuration information. In this way, the second indication information can be determined based on the smaller second value range, without having to determine the second indication information from the larger first value range, which can reduce the processing complexity of obtaining the channel information.

[0072] The following describes, in combination with several examples, how to determine the second value range corresponding to the second indication information from the first value range based on the first indication information and the first configuration information.

[0073] Example 1: The first configuration information includes a second parameter, a third parameter, a second function, a third function, and a fourth function.

[0074] Among them, the second parameter is used to characterize the distance between the first indication information and the reference point of the second value range, the third parameter is used to characterize the size of the second value range, the second function is used to constrain the reference point of the second value range to be within the first value range, the third function is used to constrain the lower limit value of the second value range to be within the first value range, and the fourth function is used to constrain the upper limit value of the second value range to be within the first value range.

[0075] As a possible example, based on Example 1, based on the first indication information and the first configuration information, determining the second value range corresponding to the second indication information from the first value range may include the following steps:

[0076] A1. Determine a second value based on the first indication information and the second parameter.

[0077] The second value may be the sum of the first indication information and the second parameter, or the difference between the first indication information and the second parameter, the quotient of the first indication information and the second parameter, the product of the first indication information and the second parameter, etc., which is not limited in the embodiments of the present disclosure. For ease of description, the embodiments of the present disclosure take the second value as the sum of the first indication information and the second parameter as an example for explanation.

[0078] A2. Determine a reference point of the second value range based on the second value, the first value range and the second function.

[0079] Illustratively, A2 may be expressed as shown in the following formula (3) and formula (4).

[0080]

[0081]

[0082] Among them, in the above formula (3)-formula (4), is the reference point of the second value range, is the second function, Δi 1,2 2 is the second parameter, i1+Δi 1,2 2 The second value.

[0083] It can be seen from the above formulas (3) and (4) that, under the constraint of the second function, when the second value is within the first value range, the value of the reference point of the second value range is determined to be the second value. When the second value is greater than the upper limit of the first value range, the value of the reference point of the second value range is determined to be the upper limit of the first value range. When the second value is less than the lower limit of the first value range, the value of the reference point of the second value range is determined to be the lower limit of the first value range.

[0084] In some embodiments, the reference point may also have other names, for example, reference point.

[0085] A3. Based on the reference point of the second value range, the third parameter and the third function, obtain the lower limit value of the second value range.

[0086] A4. Based on the reference point of the second value range, the third parameter and the fourth function, an upper limit value of the second value range is obtained.

[0087] Illustratively, A3 and A4 may be expressed as shown in the following formula (5) and formula (6).

[0088]

[0089]

[0090] In the above formula (5) and formula (6), i 2,min is the lower limit of the second value range, i 2,max is the upper limit of the second value range, i min is the lower limit of the first value range, i max is the upper limit of the first value range, δ 1,2 is the third parameter, is the third function, is the fourth function.

[0091] It can be seen from the above formula (5) that, under the constraint of the third function, when the difference between the absolute value of the reference point of the second value range and the third parameter is less than the lower limit of the first value range, the value of the lower limit of the second value range is determined to be the lower limit of the first value range. When the difference between the absolute value of the reference point of the second value range and the third parameter is greater than the lower limit of the first value range, the value of the lower limit of the second value range is determined to be the difference between the absolute value of the reference point of the second value range and the third parameter.

[0092] It can be seen from the above formula (6) that, under the constraint of the fourth function, when the sum of the absolute values ​​of the reference point of the second value range and the third parameter is less than the upper limit value of the first value range, the upper limit value of the second value range is determined to be the sum of the absolute values ​​of the reference point of the second value range and the third parameter. When the sum of the absolute values ​​of the reference point of the second value range and the third parameter is greater than the upper limit value of the first value range, the upper limit value of the second value range is determined to be the upper limit value of the first value range.

[0093] A5. Based on the lower limit value, the upper limit value and the first value range of the second value range, obtain the second value range corresponding to the second indication information.

[0094] It should be understood that I 2,minand i 2,max Afterwards, 2,min ,i 2,max ] is the second value range.

[0095] As an example, in order to ensure the accuracy of the second value range and avoid errors, the intersection of the second value range and the first value range can be used as the second value range corresponding to the second indication information, that is, [i 2,min ,i 2,max ]∩I is the second value range corresponding to the second indication information, and I is the first value range.

[0096] Example 2: The first configuration information includes a second parameter, a fourth parameter, a fifth parameter, a second function, a third function, and a fourth function.

[0097] The fourth parameter is used to characterize the distance between the reference point of the second value range and the lower limit of the second value range, and the fifth parameter is used to characterize the distance between the reference point of the second value range and the upper limit of the second value range. For the description of the second parameter, the second function, the third function and the fourth function, refer to the corresponding description in the above example 1, which will not be repeated here.

[0098] As a possible example, based on Example 2, determining the second value range corresponding to the second indication information from the first value range based on the first indication information and the first configuration information may include the following steps:

[0099] B1. Determine a second value based on the first indication information and the second parameter.

[0100] B2. Determine a reference point of the second value range based on the second value, the first value range and the second function.

[0101] For the description of B1 to B2, please refer to the above description of A1 to A2, which will not be repeated here.

[0102] B3. Based on the reference point of the second value range, the fourth parameter and the third function, obtain an optional lower limit value of the second indication information.

[0103] B4. Based on the reference point of the second value range, the fifth parameter and the fourth function, obtain an optional lower limit value of the second indication information and obtain an upper limit value of the second value range.

[0104] Illustratively, B3 and B4 may be as shown in the following formula (7) and formula (8).

[0105]

[0106]

[0107] In the above formulas (7) and (8), i 2,min is the lower limit of the second value range, i 2,max is the upper limit of the second value range, i min is the lower limit of the first value range, i max is the upper limit of the first value range, δ 1,2,L is the fourth parameter, δ 1,2,R Is the fifth parameter.

[0108] It can be seen from the above formula (7) that, under the constraint of the third function, when the difference between the absolute value of the reference point of the second value range and the fourth parameter is less than the lower limit of the first value range, the value of the lower limit of the second value range is determined to be the lower limit of the first value range. When the difference between the absolute value of the reference point of the second value range and the fourth parameter is greater than the lower limit of the first value range, the value of the lower limit of the second value range is determined to be the difference between the absolute value of the reference point of the second value range and the fourth parameter.

[0109] It can be seen from the above formula (8) that, under the constraint of the fourth function, when the sum of the absolute values ​​of the reference point of the second value range and the fifth parameter is less than the upper limit value of the first value range, the upper limit value of the second value range is determined to be the sum of the absolute values ​​of the reference point of the second value range and the fifth parameter. When the sum of the absolute values ​​of the reference point of the second value range and the fifth parameter is greater than the upper limit value of the first value range, the upper limit value of the second value range is determined to be the upper limit value of the first value range.

[0110] B5. Based on the lower limit value, the upper limit value and the first value range of the second value range, obtain the second value range corresponding to the second indication information.

[0111] For the description of B5, please refer to the above description of A5, which will not be repeated here.

[0112] It should be understood that in the above example 1, the reference point of the second value range can be understood as the center point of the second value range. 1,2,L The value of and δ 1,2,R When the values ​​of are the same, the reference point of the second value range can also be understood as the center point of the second value range. 1,2,L The value of and δ 1,2,R If the value of is different, the reference point of the second value range is not the center point of the second value range, and can be understood as the reference point of the second value range.

[0113] S202: Obtain second indication information based on a second value range corresponding to the second indication information and measurement of a second channel measurement reference signal.

[0114] In some embodiments, when the second value range corresponding to the second indication information is obtained, after the terminal receives the second measurement reference signal sent by the network side, the second channel measurement reference signal can be measured to obtain the second channel information, and then the second indication information can be obtained based on the second channel information and the second value range corresponding to the second indication information.

[0115] based on Figure 4 In the embodiment shown, after obtaining the first indication information, the second value range corresponding to the second indication information can be obtained based on the first indication information and the first configuration information, and then after receiving the second channel measurement reference signal, the second indication information can be obtained based on the second value range corresponding to the second indication information and the second channel information. In this way, the second indication information can be determined from a relatively small second value range, avoiding determining the second indication information from a relatively large first value range, narrowing the value range of the second indication information, thereby reducing the processing complexity of obtaining channel information, helping to subsequently reduce the overhead of feedback indication information and improve the performance of the communication system.

[0116] In some embodiments, Figure 5 As shown, the above step S102 may include the following steps:

[0117] S301. Determine a third value range based on first indication information and first configuration information.

[0118] The third value range may be understood as an unselectable range of the second indication information.

[0119] In some embodiments, after obtaining the first indication information, in order to quickly obtain the second indication information and reduce the processing complexity of obtaining channel information, the terminal can determine the unselectable range of the second indication information based on the first indication information and the first configuration information, that is, determine the third value range, and then determine the second value range corresponding to the second indication information based on the unselectable range of the second indication information.

[0120] The following describes, with reference to several examples, how to determine the third value range based on the first indication information and the first configuration information.

[0121] Example 3: The first configuration information includes a sixth parameter, a seventh parameter, a fifth function, a sixth function, and a seventh function.

[0122] Among them, the sixth parameter is used to characterize the distance between the first indication information and the reference point of the third value range; the seventh parameter is used to characterize the size of the third value range; the fifth function is used to constrain the reference point of the third value range to be within the first value range; the sixth function is used to constrain the lower limit value of the third value range to be within the first value range; and the seventh function is used to constrain the upper limit value of the third value range to be within the first value range.

[0123] As a possible example, based on Example 3, determining the third value range based on the first indication information and the first configuration information may include the following steps:

[0124] C1. Determine a third value based on the first indication information and the sixth parameter.

[0125] The third value may be the sum of the first indication information and the sixth parameter, or the difference between the first indication information and the sixth parameter, the quotient of the first indication information and the sixth parameter, the product of the first indication information and the sixth parameter, etc., which is not limited in the embodiment of the present disclosure. For ease of description, the embodiment of the present disclosure takes the sum of the first indication information and the sixth parameter as an example for explanation.

[0126] C2. Determine a reference point of the third value range based on the third value, the first value range and the fifth function.

[0127] Exemplarily, C2 may be expressed as shown in the following formula (9) and formula (10).

[0128]

[0129]

[0130] Among them, in the above formula (9)-formula (10), is the reference point of the third value range, is the fifth function, Δi 1,2 3 is the sixth parameter, i1+Δi 1,2 3 The third value.

[0131] It can be seen from the above formulas (9) and (10) that, under the constraints of the fifth function, when the third value is within the first value range, the value of the reference point of the third value range is determined to be the third value. When the third value is greater than the upper limit of the first value range, the value of the reference point of the third value range is determined to be the upper limit of the first value range. When the third value is less than the lower limit of the first value range, the value of the reference point of the third value range is determined to be the lower limit of the first value range.

[0132] C3. Based on the reference point of the third value range, the seventh parameter and the sixth function, a lower limit value of the third value range is obtained.

[0133] C4. Based on the reference point of the third value range, the seventh parameter and the seventh function, an upper limit value of the third value range is obtained.

[0134] Exemplarily, C3 and C4 may be expressed as shown in the following formula (11) and formula (12).

[0135]

[0136]

[0137] In the above formula (11) and formula (12), i 3,min is the lower limit of the third value range, i 3,max is the upper limit of the third value range, i min is the lower limit of the first value range, i max is the upper limit of the first value range, δ 1,2 ' is the seventh parameter, is the sixth function, The seventh function.

[0138] It can be seen from the above formula (11) that, under the constraint of the sixth function, when the difference between the absolute value of the reference point of the third value range and the seventh parameter is less than the lower limit of the first value range, the value of the lower limit of the third value range is determined to be the lower limit of the first value range. When the difference between the absolute value of the reference point of the third value range and the seventh parameter is greater than the lower limit of the first value range, the value of the lower limit of the third value range is determined to be the difference between the absolute value of the reference point of the third value range and the seventh parameter.

[0139] It can be seen from the above formula (12) that, under the constraint of the seventh function, when the sum of the absolute value of the reference point of the third value range and the seventh parameter is less than the upper limit value of the first value range, the upper limit value of the third value range is determined to be the sum of the absolute value of the reference point of the third value range and the third parameter. When the sum of the absolute value of the reference point of the third value range and the seventh parameter is greater than the upper limit value of the first value range, the upper limit value of the third value range is determined to be the upper limit value of the first value range.

[0140] C5. Obtain a third value range based on the lower limit value, the upper limit value of the third value range and the first value range.

[0141] In getting i 3,min and i 3,max Afterwards, 3,min ,i 3,max ] is the third value range.

[0142] As an example, in order to ensure the accuracy of the third value range and avoid errors, the intersection of the third value range and the first value range can be used as the third value range, that is, [i 3,min ,i 3,max ]∩I as the third value range.

[0143] Example 4: The first configuration information includes a sixth parameter, an eighth parameter, a ninth parameter, a fifth function, a sixth function, and a seventh function.

[0144] Among them, the sixth parameter is used to characterize the distance between the first indication information and the reference point of the third value range; the eighth parameter is used to characterize the distance between the reference point of the third value range and the lower limit value of the third value range; the ninth parameter is used to characterize the distance between the reference point of the third value range and the upper limit value of the third value range; the fifth function is used to constrain the reference point of the third value range to be within the first value range; the sixth function is used to constrain the lower limit value of the third value range to be within the first value range; the seventh function is used to constrain the upper limit value of the third value range to be within the first value range.

[0145] As a possible example, based on Example 4, determining the third value range based on the first indication information and the first configuration information may include the following steps:

[0146] D1. Determine a third value based on the first indication information and the sixth parameter.

[0147] D2. Determine a reference point of the third value range based on the third value, the first value range and the fifth function.

[0148] For the description of D1 to D2, reference may be made to the above description of C1 to C2, which will not be repeated here.

[0149] D3. Determine a lower limit value of the third value range based on the reference point of the third value range, the eighth parameter and the sixth function.

[0150] D4. Determine an upper limit value of the third value range based on the reference point of the third value range, the ninth parameter and the seventh function.

[0151] Illustratively, D3 and D4 may be as shown in the following formula (13) and formula (14).

[0152]

[0153]

[0154] In the above formula (13) and formula (14), i 3,min is the lower limit of the third value range, i3,max is the upper limit of the third value range, i min is the lower limit of the first value range, i max is the upper limit of the first value range, δ 1,2,L 'The eighth parameter, δ 1,2,R ' is the ninth parameter.

[0155] It can be seen from the above formula (13) that, under the constraint of the sixth function, when the difference between the absolute value of the reference point of the third value range and the eighth parameter is less than the lower limit of the first value range, the value of the lower limit of the third value range is determined to be the lower limit of the first value range. When the difference between the absolute value of the reference point of the third value range and the eighth parameter is greater than the lower limit of the first value range, the value of the lower limit of the third value range is determined to be the difference between the absolute value of the reference point of the third value range and the eighth parameter.

[0156] It can be seen from the above formula (14) that, under the constraint of the seventh function, when the sum of the absolute values ​​of the reference point of the third value range and the ninth parameter is less than the upper limit value of the first value range, the upper limit value of the third value range is determined to be the sum of the absolute values ​​of the reference point of the third value range and the ninth parameter. When the sum of the absolute values ​​of the reference point of the third value range and the ninth parameter is greater than the upper limit value of the first value range, the upper limit value of the third value range is determined to be the upper limit value of the first value range.

[0157] D5. Obtain a third value range based on the lower limit value, the upper limit value and the first value range of the third value range.

[0158] For the description of D5, please refer to the above description of C5, which will not be repeated here.

[0159] S302: Exclude the third value range from the first value range to obtain a second value range.

[0160] It can be seen from the above description that the third value range may be a non-selectable range of the second indication information. Therefore, after obtaining the third value range, the third value range may be excluded from the first value range to obtain the second value range.

[0161] Exemplarily, the relationship among the first value range, the second value range and the third value range can be shown as the following formula (15).

[0162] R=I-[i 3,min ,i 3,max ] Formula (15);

[0163] Among them, R is the second value range.

[0164] As an example, in order to ensure the accuracy of the second value range and avoid errors, the relationship between the first value range, the second value range and the third value range can be as shown in the following formula (16).

[0165] R=I-[i 3,min ,i 3,max ]∩I formula (16);

[0166] in, i is a value in the third value range.

[0167] based on Figure 5 In the embodiment shown, after obtaining the first indication information, the terminal can determine the unselectable range of the second indication information based on the first indication information and the first configuration information, that is, determine the third value range, and then determine the second value range corresponding to the second indication information based on the unselectable range of the second indication information and the first value range, and then determine the second indication information from the second value range, avoiding determining the second indication information from the first value range with a larger range, thereby reducing the processing complexity of obtaining the channel information, helping to subsequently reduce the overhead of the feedback indication information and improve the performance of the communication system.

[0168] In some embodiments, Figure 6 As shown, the embodiment of the present disclosure also provides a method for obtaining channel information, which is applied to a terminal, and the terminal may be the above Figure 2 The terminal 110 shown in the figure comprises the following steps:

[0169] S401: Obtain second configuration information.

[0170] In some embodiments, in order to quickly obtain the first indication information corresponding to the first channel information and the second indication information corresponding to the second channel information to reduce the processing complexity of obtaining the channel information, the terminal obtains the second configuration information before receiving the first channel measurement reference signal and the second channel measurement reference signal to determine the value range of the first indication information and the value range of the second indication information. The second configuration information is used to configure the correspondence between the first indication information corresponding to the first channel information and the second indication information corresponding to the second channel information in terms of the value range. The second configuration information is preconfigured or configured on the network side. The terminal obtains the second configuration information by obtaining the preconfigured second configuration information from its own memory or by receiving the second configuration information sent by the network side. The embodiments of the present disclosure do not limit the manner in which the terminal obtains the second configuration information.

[0171] S402: Obtain first indication information based on the second configuration information and measurement of a first channel measurement reference signal.

[0172] In some embodiments, after receiving the first channel measurement reference signal and the second channel measurement reference signal, the terminal can measure the first channel measurement reference signal to obtain first channel information, and then obtain first indication information corresponding to the first channel information based on the first channel information and the second configuration information.

[0173] In some embodiments, the second configuration information includes at least one configuration parameter of the fourth value range of the first indication information and at least one configuration parameter of the fifth value range of the second indication information, and each fourth value range corresponds to a fifth value range. That is, the value range of the first indication information is associated with the value range of the second indication information.

[0174] It should be noted that a fourth value range may be an optional range of the first indication information, that is, the first indication information can be determined from the fourth value range, or an unselectable range of the first indication information, that is, the first indication information cannot be determined from the fourth value range. A fifth value range may be an optional range of the second indication information, that is, the second indication information can be determined from the fifth value range, or an unselectable range of the second indication information, that is, the second indication information cannot be determined from the fifth value range. As for how the terminal determines that at least one fourth value range and at least one fifth value range indicated by the second configuration information are respectively the optional range or unselectable range of the first indication information and the second indication information, it may be that the terminal and the network side have pre-negotiated that at least one fourth value range and at least one fifth value range indicated by the second configuration information are the optional range or unselectable range of the first indication information and the second indication information, or it may be that before the terminal receives the first channel measurement reference signal and the second channel measurement reference signal, the network side sends indication information to the terminal, and the indication information is used to indicate that at least one fourth value range and at least one fifth value range indicated by the second configuration information are respectively the optional range or unselectable range of the first indication information and the second indication information, and the embodiment of the present disclosure does not limit this.

[0175] In some embodiments, the second configuration information includes a first value range, and the value of the first indication information and the value of the second indication information both belong to the first value range.

[0176] As an example, based on the second configuration information and the measurement of the first channel measurement reference signal, the first indication information is obtained, and the terminal may obtain the first indication information based on the target fourth value range and the measurement of the first channel measurement reference signal. The target fourth value range is one of the at least one fourth value range.

[0177] In some embodiments, the target fourth value range may be pre-negotiated between the terminal and the network side, or may be indicated by the network side, and the embodiments of the present disclosure are not limited to this.

[0178] It can be seen from the above description of the second configuration information that the second configuration information includes at least one configuration parameter of the fourth value range of the first indication information. After the terminal obtains the second configuration information, the terminal can obtain at least one fourth value range of the first indication information based on the at least one configuration parameter of the fourth value range. After receiving the first channel measurement reference signal, the terminal can measure the first channel measurement reference signal to obtain the first channel information, and then obtain the first indication information based on the first channel information and the target fourth value range.

[0179] In some embodiments, the configuration parameter of the fourth value range includes an upper limit value of the fourth value range and a lower limit value of the fourth value range. For each fourth value range in at least one fourth value range, the terminal can obtain the fourth value range based on the upper limit value and the lower limit value of a fourth value range.

[0180] S403: Obtain second indication information based on the second configuration information and measurement of a second channel measurement reference signal.

[0181] As an example, based on the second configuration information and the measurement of the second channel measurement reference signal, the second indication information is obtained, and the terminal may obtain the second indication information based on the target fifth value range and the measurement of the second channel measurement reference signal. Wherein, the target fifth value range is one of at least one fifth value range.

[0182] In some embodiments, the target fifth value range may be pre-negotiated between the terminal and the network side, or may be indicated by the network side, and the embodiments of the present disclosure are not limited to this.

[0183] From the above description of the second configuration information, it can be known that the second configuration information includes at least one configuration parameter of the fifth value range of the second indication information. After the terminal obtains the second configuration information, the terminal can obtain at least one fifth value range of the second indication information based on the at least one configuration parameter of the fifth value range. After receiving the second channel measurement reference signal, the terminal can measure the second channel measurement reference signal to obtain the second channel information, and then obtain the second indication information based on the second channel information and the target fifth value range.

[0184] In some embodiments, the configuration parameters of the fifth value range include an upper limit value of the fifth value range and a lower limit value of the fifth value range. For each fifth value range in at least one fifth value range, the terminal can obtain the fifth value range based on the upper limit value and the lower limit value of a fifth value range.

[0185] It should be noted that the embodiment of the present disclosure does not limit the execution order of step S402 and step S403. For example, step S402 may be executed first, and then step S403; for another example, step S403 may be executed first, and then step S402; for another example, step S402 and step S403 may be executed simultaneously.

[0186] The second configuration information is described below with reference to several specific examples.

[0187] Exemplarily, taking the second configuration information including a configuration parameter in the fourth value range and a configuration parameter in the fifth value range as an example, assuming that the second configuration information is (S 1，min , S 1，max , S 2，min , S 2，max ), where S 1，min is the lower limit of the fourth value range, S 1，max is the upper limit of the fourth value range, S 2，min is the lower limit of the fifth value range, S 2，max is the upper limit of the fifth value range.

[0188] In the case where the terminal and the network side have pre-negotiated or the network side has pre-indicated that the fourth value range is an optional range of the first indication information, and the fifth value range is an optional range of the second indication information, the terminal may select [S 1，min , S 1，max ]∩I determine the first indication information, and based on the second channel information, from [S 2，min , S 2，max ]∩I determines the second indication information, where I is the first value range.

[0189] In the case where the terminal and the network side have pre-negotiated or the network side has pre-indicated that the fourth value range is an unselectable range of the first indication information and the fifth value range is an unselectable range of the second indication information, the terminal can select R1=I-[S 1，min , S 1，max ]∩I to determine the first indication information, and based on the second channel information, from R2=I-[S 2，min , S 2，max ]∩I determines the second indication information, R1 is the optional range of the first indication information, and R2 is the optional range of the second indication information.

[0190] Exemplarily, taking the second configuration information including two configuration parameters in the fourth value range and two configuration parameters in the fifth value range as an example, assuming that the second configuration information is (S 1，1，min , S 1，1，max, S 1，2，min , S 1，2，max , S 2，1，min , S 2，1，max , S 2，2，min , S 2，2，max ), where S 1，1，min is the lower limit of the first fourth value range, S 1，1，max is the upper limit of the first fourth value range, S 1，2，min is the lower limit of the second fourth value range, S 1，2，max is the upper limit of the second fourth value range. 2，1，min is the lower limit of the first fifth value range, S 2，1，max is the upper limit of the first fifth value range, S 2，2，min is the lower limit of the second fifth value range, S 2，2，max is the upper limit of the second fifth value range. The first fourth value range corresponds to the first fifth value range, and the second fourth value range corresponds to the second fifth value range.

[0191] In the case where the terminal and the network side have pre-negotiated or the network side has pre-indicated that the fourth value range is an optional range of the first indication information, and the fifth value range is an optional range of the second indication information, the terminal may select [S 1，1，min， S 1，1，max ]∩I determine the first indication information, and based on the second channel information, from [S 2，1，min , S 2，1，max ]∩I determines the second indication information.

[0192] Alternatively, the terminal may, based on the first channel information, obtain 1，2，min , S 1，2，max ]∩I determine the first indication information, and based on the second channel information, from [S 2，2，min , S 2，2，max ]∩I determines the second indication information.

[0193] In the case where the terminal and the network side have pre-negotiated or the network side has pre-indicated that the fourth value range is an unselectable range of the first indication information and the fifth value range is an unselectable range of the second indication information, the terminal can select R3=I-[S 1，1，min , S 1，1，max ]∩I determine the first indication information, and based on the second channel information, from R4=I-[S 2，1，min , S 2，1，max ]∩I determines the second indication information, R3 is the optional range of the first indication information, and R4 is the optional range of the second indication information.

[0194] Alternatively, the terminal may, based on the first channel information, select R5=I-[S 1，2，min , S 1，2，max ]∩I determine the first indication information, and based on the second channel information, from R6=I-[S 2，2，min , S 2，2，max ]∩I determines the second indication information, R5 is the optional range of the first indication information, and R6 is the optional range of the second indication information.

[0195] It should be noted that the above embodiments in which the second configuration information includes a configuration parameter in the fourth value range and a configuration parameter in the fifth value range, or the second configuration information includes two configuration parameters in the fourth value range and two configuration parameters in the fifth value range are merely exemplary. The embodiments of the present disclosure do not limit the number of configuration parameters in the fourth value range and configuration parameters in the fifth value range included in the second configuration information.

[0196] based on Figure 6 In the embodiment shown, the terminal obtains the second configuration information to associate the value ranges of the independent first indication information and the second indication information, thereby narrowing the selection range of the first indication information and the second indication information, and avoiding determining the first indication information and the second indication information from a larger first value range, thereby reducing the processing complexity of obtaining the channel information, helping to subsequently reduce the overhead of the feedback indication information and improve the performance of the communication system.

[0197] In some embodiments, after obtaining the first indication information and the second indication information, that is, after the above step S102 or step S403, as Figure 7 , the method may further comprise the following steps:

[0198] S501. Send first indication information and second indication information to a network side.

[0199] The network side may be a base station, an antenna array panel on the base station, or an antenna element port on the antenna array panel on the base station. The first indication information is used to indicate the first channel information, and the second indication information is used to indicate the second channel information.
