For example, without departing from the scope of the embodiments of the present disclosure, the first indication information may also be referred to as the second indication information, and similarly, the second indication information may also be referred to as the first indication information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to"

[0120] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0121] As shown in Figure 1A, the method provided in the embodiment of the present disclosure can be applied to a wireless communication system 100, which may include a terminal 101 and a network device 102. It should be noted that the wireless communication system 100 may also include other devices, and this application does not limit the devices included in the wireless communication system 100.

[0122] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for micro wave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems, Internet of Things systems, etc.

[0123] The terminal 101 shown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, an Internet of Things terminal, etc. The terminal 101 may have wireless transceiver capabilities, and may be capable of communicating (e.g., wirelessly communicating) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0124] Among them, the terminal 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a future 5G network, or a terminal in a future evolved PLMN network, etc.

[0125] In an embodiment of the present disclosure, a terminal may be configured to transmit a sounding reference signal on a receiving antenna to measure the channel condition associated with each receiving antenna. The terminal may have four receiving antennas, or more than four receiving antennas, for example, eight receiving antennas. Different terminals have different SRS transmit switching capabilities (SRS-TxSwitch capability), and the terminal reports the SRS transmit switching capability to the network device. In one example, the SRS transmit switching capability may be one of the following:

[0126] In 1T2R, the terminal transmits SRS on two antennas in turn, selecting one antenna to transmit at a time.

[0127] In 1T4R, the terminal transmits SRS on four antennas in turn, selecting one antenna to transmit at a time.

[0128] 2T4R: The terminal transmits SRS on four antennas in turn, selecting two antennas to transmit at a time.

[0129] In 1T8R, the terminal transmits SRS on eight antennas in turn, selecting one antenna to transmit at a time.

[0130] 2T8R: The terminal transmits SRS on 8 antennas in turn, selecting 2 antennas to transmit at a time.

[0131] FIG1B is a schematic diagram of a 1T4R structure provided according to an embodiment of the present disclosure.

[0132] When the terminal transmits the SRS on different receiving antennas in turn, the SRS is transmitted via different antennas, so that the signal insertion losses between the different antennas are different.

[0133] In one example, as shown in Figure 2, in a 1T4R structure, receiving antennas 2, 3, and 4 correspond to different receiving modules, and main antenna 1 corresponds to the main transceiver module. Compared with main antenna 1, receiving antennas 2, 3, and 4 need to consider the insertion loss of the single-pole double-throw (SPDT) switch and the additional line loss. In some protocols, ΔT is used. RxSRS Represents antenna switching loss.

[0134] Therefore, when the terminal transmits SRS on different receiving antennas in turn, the SRS power output on different receiving antennas will be unbalanced, which will cause large estimation errors when the network equipment uses SRS to estimate channel quality, thereby affecting system performance.

[0135] With the introduction of more receiving antennas, such as 1T8R and 2T8R, the ΔT RxSRSIt will become larger and larger, thereby reducing the estimation accuracy of the network equipment when using SRS to estimate the channel quality, and is not conducive to improving the benefits of the antenna switching function.

[0136] FIG2A is an interactive diagram of a method for reporting compensation parameters according to an embodiment of the present disclosure, as shown in FIG3 , including the following steps:

[0137] Step S2101 : The network device 102 sends first configuration information to the terminal 101 .

[0138] In some embodiments, the first configuration information includes information for configuring an SRS resource set.

[0139] In some embodiments, the SRS resource set includes information indicating the number of SRS ports.

[0140] Step S2102 , the network device 102 sends second configuration information to the terminal 101 .

[0141] In some embodiments, the second configuration information is used to configure the first value.

[0142] In some embodiments, the first value is used for: the terminal to send the first indication information when the difference between the compensation parameter and the compensation parameter sent historically is greater than the first value.

[0143] Step S2103: Terminal 101 determines at least one compensation parameter.

[0144] In some embodiments, the compensation parameter is used to compensate for estimation deviation generated when the network device uses a sounding reference signal SRS to perform channel estimation.

[0145] In some embodiments, the compensation parameter is a compensation value.

[0146] In some embodiments, the compensation parameter is a range of values.

[0147] In some embodiments, the compensation parameter is a value range of the compensation value.

[0148] In one example, the compensation parameter is a specific value. When the number of compensation parameters is 3, the first compensation parameter is 2 dB, the second compensation parameter is 4 dB, and the third compensation parameter is 6 dB.

[0149] In one example, the compensation parameter is a value range. When the number of compensation parameters is 3, the first compensation parameter is 0 to 2 dB, the second compensation parameter is 2 to 4 dB, and the third compensation parameter is 4 to 6 dB.

[0150] In some embodiments, the terminal 101 determines that the number of compensation parameters is 1, that is, the terminal 101 determines one compensation parameter.

[0151] In some embodiments, terminal 101 determines the number of compensation parameters according to the first number and the second number.

[0152] In some embodiments, the first number is the number of receive antennas used to transmit the SRS.

[0153] In some embodiments, the second number is the number of SRS ports.

[0154] In some embodiments, the number of compensation parameters is determined as a difference between a first ratio and 1, wherein the first ratio is a ratio of the first number to the second number.

[0155] In one example, the SRS transmission switching capability is 1T2R, so the first number is determined to be 2. The number of SRS ports is 1, so the second number is determined to be 1. The number of compensation parameters is determined to be 1 based on the first and second numbers, so one compensation parameter is marked as CF(1).

[0156] In one example, the SRS transmission switching capability is 1T4R, thereby determining the first number to be 4. The number of SRS ports is 1, thereby determining the second number to be 1. The number of compensation parameters is determined to be 3 based on the first number and the second number, thereby marking the three compensation parameters as CF(1), CF(2), and CF(3).

[0157] In one example, the SRS transmission switching capability is 2T4R, thereby determining the first number to be 4. The number of SRS ports is 1, thereby determining the second number to be 1. The number of compensation parameters is determined to be 3 based on the first number and the second number, thereby marking the three compensation parameters as CF(1), CF(2), and CF(3).

[0158] In one example, the SRS transmission switching capability is 2T4R, thereby determining the first number to be 4. The number of SRS ports is 2, thereby determining the second number to be 2. The number of compensation parameters is determined to be 1 based on the first number and the second number, thereby marking the three compensation parameters as CF(1).

[0159] In one example, the SRS transmission switching capability is 1T8R, thereby determining the first number to be 8. The number of SRS ports is 1, thereby determining the second number to be 1. The number of compensation parameters is determined to be 7 based on the first number and the second number, thereby marking the three compensation parameters as CF(1) to CF(7).

[0160] In one example, the SRS transmission switching capability is 2T8R, thereby determining the first number to be 8. The number of SRS ports is 1, thereby determining the second number to be 1. The number of compensation parameters is determined to be 7 based on the first number and the second number, thereby marking the 7 compensation parameters as CF(1) to CF(7).

[0161] In one example, the SRS transmission switching capability is 2T8R, thereby determining the first number to be 8. The number of SRS ports is 2, thereby determining the second number to be 2. The number of compensation parameters is determined to be 3 based on the first number and the second number, thereby marking the three compensation parameters as CF(1), CF(2), and CF(3).

[0162] In some embodiments, at least one compensation parameter corresponds to a first antenna, the first antenna being determined based on SRS transmission switching capability.

[0163] In some embodiments, when the terminal 101 determines one compensation parameter, the one compensation parameter corresponds to each first antenna.

[0164] In some embodiments, when terminal 101 determines more than one compensation parameter, different compensation parameters correspond to at least one of the first antennas.

[0165] In step S2104 , the terminal 101 determines at least one of the first value and the second value.

[0166] In some embodiments, the first value is used for: the terminal to send the first indication information when the difference between the compensation parameter and the compensation parameter sent historically is greater than the first value.

[0167] In some embodiments, the second value is used for: the terminal 101 sends the first indication information in response to the transmission power of the SRS being greater than or equal to the second value.

[0168] In this embodiment, when the SRS transmission power is greater than or equal to the second value, the terminal 101 cannot ensure the output power balance of each antenna through its own power compensation, so the network device needs to perform compensation during channel estimation.

[0169] In some embodiments, when the SRS transmission power is less than the second value, the terminal 101 ensures the output power balance of each antenna through its own power compensation, thereby eliminating the need for network equipment to perform compensation during channel estimation.

[0170] Step S2105 , the terminal 101 sends first indication information to the network device 102 .

[0171] In some embodiments, the first indication information is used to indicate at least one compensation parameter.

[0172] In some embodiments, the compensation parameter is used to compensate for estimation errors generated when the network device uses the SRS to perform channel estimation.

[0173] In some embodiments, the compensation parameter is a compensation value.

[0174] In some embodiments, the compensation parameter is a value range of the compensation value.

[0175] In some embodiments, the first indication information includes multiple fields, each field occupies N bits, and each field indicates a value range of a compensation parameter, where N is an integer greater than or equal to 1.

[0176] In one example, the value of N is 2, the first indication information includes 4 fields, each field occupies 2 bits, and every 2 bits indicate a value range.

[0177] In some embodiments, the terminal 101 sends the first indication information in response to the compensation parameter being different from the compensation parameter sent historically by a degree greater than a first value.

[0178] In some embodiments, the first value is agreed upon according to a protocol.

[0179] In some embodiments, the first value is determined by terminal 101 .

[0180] In some embodiments, the first value is indicated in the second configuration information.

[0181] In some embodiments, the terminal 101 sends the first indication information in response to the transmission power of the SRS being greater than or equal to the second value.

[0182] In some embodiments, the terminal 101 sends the first indication information in response to a change in the first configuration information.

[0183] In some embodiments, the terminal 101 sends the first indication information in response to a change in the second quantity in the first configuration information.

[0184] In step S2106 , the network device 102 determines a first antenna.

[0185] In some embodiments, the network device 101 determines the first antenna according to SRS transmission switching capability.

[0186] In some embodiments, the network device 101 determines the first antenna according to a first method.

[0187] The first method includes:

[0188] When the number of transmitting antennas in the SRS transmission switching capability of the terminal 101 is equal to 1, the first antenna is the antenna other than the main antenna among the antennas used for transmitting the SRS, and the number of the main antenna is 1.

[0189] When the number of transmitting antennas in the SRS transmission switching capability of the terminal 101 is greater than 1, the first antenna is an antenna other than the main antenna among the antennas used to transmit the SRS.

[0190] In this embodiment, the insertion loss caused by switching between main antennas is considered negligible, so when the number of transmitting antennas in the SRS transmission switching capability is greater than 1, the main antenna is not used as the first antenna, that is, no compensation parameters are configured for the main antenna.

[0191] In some embodiments, the number of primary antennas is the same as the number of transmit antennas in the SRS transmit switching capability.

[0192] In one example, when the SRS transmission switching capability is 2T4R, the number of main antennas is 2.

[0193] In one example, when the SRS transmission switching capability is 1T4R, the number of primary antennas is 1.

[0194] In one example, when the SRS transmission switching capability is 2T8R, the number of main antennas is 2.

[0195] In one example, when the SRS transmission switching capability is 1T8R, the number of main antennas is 1.

[0196] In some embodiments, the primary antenna has the following capabilities:

[0197] Send uplink service data;

[0198] Send SRS;

[0199] Receive downlink service data.

[0200] In some embodiments, terminal 101 includes a main antenna and a diversity antenna. The diversity antenna has the following capabilities:

[0201] No uplink service data is sent;

[0202] Send SRS;

[0203] Receive downlink service data.

[0204] In some embodiments, the difference in capabilities between the main antenna and the diversity antenna is that the main antenna can send uplink service data, while the diversity antenna cannot send uplink service data.

[0205] In one example, in conjunction with Table 1, when the network device 102 receives a compensation parameter, the network device 102 determines the first antenna according to the first method when having different SRS transmission switching capabilities.

[0206] Table 1

[0207] In this example, terminal 101 has eight antennas, including A1, A2, ..., and A8. Terminal 101 determines a compensation parameter, denoted as CF. " / " in Table 1 indicates that there is no corresponding CF.

[0208] The following is an explanation of Table 1 item by item:

[0209] Item 1: The SRS transmission switching capability is 1T2R. Antennas A1 and A2 are used to transmit SRS. A1 is the main antenna, and A2 is the diversity antenna. The antennas other than the main antenna that require compensation parameters are the antennas used to transmit SRS, meaning that the antenna that requires compensation parameters is A2. Therefore, in item 1, the compensation parameters correspond to A2.

[0210] Item 2: The SRS transmit switching capability is 1T4R. The antennas used for SRS transmission are A1, A2, A3, and A4. A1 is the main antenna, and A2, A3, and A4 are diversity antennas. Compensation parameters are required for antennas other than the main antenna used for SRS transmission, meaning that compensation parameters are required for antennas A2, A3, and A4. Therefore, in item 2, the compensation parameters correspond to A2, A3, and A4.

[0211] Item 3: The SRS transmit switching capability is 2T4R, and the number of SRS ports is 1. The antennas used for SRS transmission are A1, A2, A3, and A4. A1 and A2 are the main antennas, and A3 and A4 are the diversity antennas. Compensation parameters are applied to the antennas other than the main antenna used for SRS transmission, meaning that compensation parameters are applied to antennas A3 and A4. Therefore, in item 3, the compensation parameters correspond to A3 and A4.

[0212] Item 4: The SRS transmit switching capability is 1T8R, and the number of SRS ports is 1. Antennas A1 through A8 are used to transmit SRS. A1 is the main antenna, and A2 through A8 are diversity antennas. Compensation parameters are required for antennas other than the main antenna used to transmit SRS, meaning that compensation parameters are required for antennas A2 through A8. Therefore, in item 5, the compensation parameters correspond to antennas A2 through A8.

[0213] Item 5: The SRS transmit switching capability is 2T8R, and the number of SRS ports is 1. Antennas A1 through A8 are used to transmit SRS. A1 and A2 are the main antennas, and A3 through A8 are diversity antennas. Compensation parameters are required for antennas other than the main antenna used to transmit SRS, meaning that antennas A3 through A8 require compensation parameters. Therefore, in item 6, the compensation parameters correspond to antennas A3 through A8.

[0214] In some embodiments, the network device 102 determines the first antenna according to a second method.

[0215] The second method includes:

[0216] When the number of transmitting antennas in the SRS transmission switching capability of the terminal 101 is equal to 1, the first antenna is the antenna other than the main antenna among the antennas used for transmitting the SRS, and the number of the main antenna is 1.

[0217] When the number of transmitting antennas in the SRS transmission switching capability of the terminal 101 is greater than 1, the first antenna is the antenna other than the reference antenna among the antennas used to transmit the SRS.

[0218] In this embodiment, it is considered necessary to consider the impact of insertion loss caused by switching between main antennas. Therefore, when the number of transmitting antennas in the SRS transmission switching capability is greater than 1, the main antenna is used as the first antenna, that is, compensation parameters are configured for the main antenna.

[0219] In some embodiments, the reference antenna is a default one of the terminal's main antennas.

[0220] In some embodiments, one of the multiple antennas of the terminal is used as the main antenna and the reference antenna by default.

[0221] In one example, the terminal has eight antennas, one of which is used as a main antenna and a reference antenna by default.

[0222] In some embodiments, the number of primary antennas is the same as the number of transmit antennas in the SRS transmit switching capability.

[0223] In one example, when the SRS transmission switching capability is 2T4R, the number of main antennas is 2.

[0224] In one example, when the SRS transmission switching capability is 1T4R, the number of primary antennas is 1.

[0225] In one example, when the SRS transmission switching capability is 2T8R, the number of main antennas is 2.

[0226] In one example, when the SRS transmission switching capability is 1T8R, the number of main antennas is 1.

[0227] In some embodiments, the primary antenna has the following capabilities:

[0228] Send uplink service data;

[0229] Send SRS;

[0230] Receive downlink service data.

[0231] In some embodiments, terminal 101 includes a main antenna and a diversity antenna. The diversity antenna has the following capabilities:

[0232] No uplink service data is sent;

[0233] Send SRS;

[0234] Receive downlink service data.

[0235] In some embodiments, the difference in capabilities between the main antenna and the diversity antenna is that the main antenna can send uplink service data, while the diversity antenna cannot send uplink service data.

[0236] In one example, in conjunction with Table 2, when the network device 102 receives a compensation parameter, the network device 102 determines the first antenna according to the second manner when having different SRS transmission switching capabilities.

[0237] Table 2

[0238] In this example, terminal 101 has eight antennas, including A1, A2, ..., and A8. Terminal 101 determines a compensation parameter, denoted as CF. " / " in Table 1 indicates that there is no corresponding CF.

[0239] The following explains the difference between Table 2 and Table 1:

[0240] The difference between Table 2 and Table 1 lies in items 3 and 5.

[0241] When the number of transmit antennas in terminal 101's SRS transmission switching capability is greater than one, the first antenna in Table 1 refers to the antennas used for SRS transmission excluding the primary antenna, meaning that the CF does not correspond to any primary antenna. However, the first antenna in Table 2 refers to the antennas used for SRS transmission excluding the reference antenna, meaning that the CF corresponds to the primary antenna excluding the reference antenna. Therefore, the difference between Table 2 and Table 1 lies in items 3 and 5.

[0242] In the third item in Table 1, antenna 2 is the main antenna and does not correspond to CF, while in the third item in Table 2, antenna 2 is the main antenna and also corresponds to CF.

[0243] In item 5 of Table 2, antenna 2 is the main antenna and does not correspond to CF, while in item 5 of Table 2, antenna 2 is the main antenna and also corresponds to CF.

[0244] In one example, Table 3 is used to describe how the network device 102 determines the number of compensation parameters according to the first number and the second number, and how to determine the first antenna according to the first method when having different SRS transmission switching capabilities.

[0245] Table 3

[0246] In Table 3, the method for the terminal 101 to determine the number of compensation parameters is: the difference between the first ratio and 1, where the first ratio is the ratio of the first number to the second number.

[0247] The following is an explanation of Table 3 item by item:

[0248] Item 1:

[0249] A compensation parameter is received, specifically CF(1).

[0250] Determine the first antenna: The SRS transmission switching capability is 1T2R, so the antennas used for SRS transmission are determined to be A1 and A2. A1 is the main antenna, and A2 is the diversity antenna. The antennas used for SRS transmission that require compensation parameters are the antennas other than the main antenna, that is, the first antenna is A2.

[0251] Thus in term 1, CF(1) corresponds to A2.

[0252] Item 2:

[0253] Receive three compensation parameters, specifically CF(1), CF(2), CF(3)

[0254] Determine the first antenna: The SRS transmission switching capability is 1T4R. Therefore, the antennas used for SRS transmission are determined to be A1, A2, A3, and A4. A1 is the main antenna, and A2, A3, and A4 are diversity antennas. The antennas used for SRS transmission that require compensation parameters are the antennas other than the main antenna, meaning that the first antennas are A2, A3, and A4.

[0255] Therefore, in item 2, CF(1), CF(2), and CF(3) correspond to A2, A3, and A4. Since the number of compensation parameters is the same as the number of first antennas, they can be matched sequentially, that is, one-to-one matching is performed according to the order of arrangement of the multiple compensation coefficients and the order of arrangement of the antenna numbers of the first antenna. For example, as shown in Table 3: CF(1) corresponds to A2, CF(2) corresponds to A3, and CF(3) corresponds to A4.

[0256] Item 3:

[0257] Three compensation parameters are received, specifically CF(1), CF(2), and CF(3).

[0258] Determine the first antenna: The SRS transmission switching capability is 2T4R. Therefore, the antennas used for SRS transmission are determined to be A1, A2, A3, and A4. A1 and A2 are the main antennas, and A3 and A4 are the diversity antennas. The antennas that require compensation parameters are the antennas used for SRS transmission other than the main antenna, that is, the first antennas are A3 and A4.

[0259] Therefore, in item 3, CF(1), CF(2), and CF(3) correspond to A3 and A4. Since the number of compensation parameters is greater than the number of first antennas, some of the compensation parameters can correspond to the multiple first antennas in sequence, with a one-to-one correspondence between the order of arrangement of the compensation coefficients in the multiple compensation coefficients and the order of arrangement of the antenna numbers of the first antennas. The number of the compensation coefficients is the same as the number of first antennas. For example, as shown in Table 3, CF(1) corresponds to A3, and CF(2) corresponds to A4.

[0260] Item 4:

[0261] A compensation parameter is received, specifically CF(1).

[0262] Determine the first antenna: The SRS transmission switching capability is 2T4R. Therefore, the antennas used for SRS transmission are determined to be A1, A2, A3, and A4. A1 and A2 are the main antennas, and A3 and A4 are the diversity antennas. The antennas that require compensation parameters are the antennas used for SRS transmission other than the main antenna, that is, the first antennas are A3 and A4.

[0263] Therefore, in item 4, CF(1) corresponds to A3 and A4. Since the number of compensation parameters is 1, one compensation parameter can be corresponding to any first antenna. For example, as shown in Table 3: CF(1) corresponds to A3, and CF(1) corresponds to A4.

[0264] Item 5:

[0265] Seven compensation parameters are received, specifically CF(1) to CF(7).

[0266] Determine the first antenna: The SRS transmission switching capability is 1T8R. Therefore, antennas A1 through A8 are used to transmit SRS. A1 is the main antenna, and A2 through A8 are diversity antennas. The antennas that require compensation parameters are those used to transmit SRS, excluding the main antenna. Therefore, the first antennas are A2 through A8.

[0267] Therefore, in item 5, CF(1) to CF(7) correspond to A2 to A8. Since the number of compensation parameters is the same as the number of first antennas, they can be matched sequentially, that is, one-to-one matching is performed according to the order of arrangement of the multiple compensation coefficients and the order of arrangement of the antenna numbers of the first antenna. For example, as shown in Table 3: CF(1) corresponds to A2, CF(2) corresponds to A3, ..., CF(7) corresponds to A8.

[0268] Item 6:

[0269] Seven compensation parameters are received, specifically CF(1) to CF(7).

[0270] Determine the first antenna: The SRS transmit switching capability is 2T8R, which determines that antennas A1 through A8 are used to transmit SRS. A1 and A2 are the main antennas, and A3 through A8 are the diversity antennas. The antennas that require compensation parameters are those used to transmit SRS, excluding the main antenna. Therefore, the first antennas are A3 through A8.

[0271] Therefore, in item 6, CF(1) to CF(7) correspond to A3 to A8. Since the number of compensation parameters is greater than the number of first antennas, some of the compensation parameters can correspond to the multiple first antennas in sequence, with a one-to-one correspondence between the order of arrangement of the compensation coefficients and the order of arrangement of the antenna numbers of the first antennas. The number of the compensation coefficients is the same as the number of first antennas. For example, as shown in Table 3: CF(1) corresponds to A3, CF(2) corresponds to A4, and CF(6) corresponds to A7.

[0272] Item 7:

[0273] Receive three compensation parameters, specifically CF(1), CF(2), and CF(3).

[0274] Determine the first antenna: The SRS transmit switching capability is 2T8R, which determines that antennas A1 through A8 are used to transmit SRS. A1 and A2 are the main antennas, and A3 through A8 are the diversity antennas. The antennas that require compensation parameters are those used to transmit SRS, excluding the main antenna. Therefore, the first antennas are A3 through A8.

[0275] Thus, in item 7, CF(1) to CF(3) correspond to A3 to A8. Since the number of compensation parameters is less than the number of first antennas, one compensation parameter may correspond to more than one first antenna. When the number of compensation parameters is less than the number of first antennas and the number of first antennas is an integer multiple of the number of compensation parameters, one compensation parameter corresponds to N first antennas, where N is a multiple of the number of first antennas and the number of compensation parameters.

[0276] For example, as shown in Table 3: CF(1) corresponds to A3, CF(2) corresponds to A4, CF(1) corresponds to A5, CF(2) corresponds to A6, CF(1) corresponds to A7, and CF(2) corresponds to A8.

[0277] In some embodiments, the network device 102 determines the first antenna according to a second method.

[0278] The first method includes:

[0279] When the number of transmitting antennas in the SRS transmission switching capability of the terminal 101 is equal to 1, the first antenna is the antenna other than the main antenna among the antennas used for transmitting the SRS, and the number of the main antenna is 1.

[0280] When the number of transmitting antennas in the SRS transmission switching capability of the terminal 101 is greater than 1, the first antenna is the antenna other than the reference antenna among the antennas used to transmit the SRS.

[0281] In an example, Table 4 is used to describe how the network device 102 determines the number of compensation parameters according to the first number and the second number, and how to determine the first antenna according to the second method when having different SRS transmission switching capabilities.

[0282] Table 4

[0283] The following explains the difference between Table 4 and Table 3:

[0284] The difference between Table 4 and Table 3 lies in items 3 and 5.

[0285] When the number of transmitting antennas in terminal 101's SRS transmission switching capability is greater than one, the first antenna in Table 1 refers to the antennas used for SRS transmission excluding the main antenna, i.e., CF does not correspond to any main antenna. However, the first antenna in Table 2 refers to the antennas used for SRS transmission excluding the reference antenna, i.e., CF corresponds to the main antenna excluding the reference antenna. Therefore, the difference between Table 2 and Table 1 lies in items 3, 4, 6, and 7.

[0286] In item 3, antenna 2 is the primary antenna and does not correspond to CF. However, in item 3 of Table 2, antenna 2 is the primary antenna and also corresponds to CF. Furthermore, three compensation parameters are determined in item 3, so these three compensation parameters correspond to A2, A3, and A4.

[0287] In item 4, antenna 2 is the primary antenna and does not correspond to CF, whereas in item 4 of Table 2, antenna 2 is the primary antenna and also corresponds to CF. Furthermore, only one compensation parameter is determined in item 4, so this one compensation parameter corresponds to A2, A3, and A4.

[0288] In item 6, antenna 2 is the primary antenna and does not correspond to CF. However, in item 6 of Table 2, antenna 2 is the primary antenna and also corresponds to CF. Furthermore, 7 compensation parameters are determined in item 6, so these 7 compensation parameters correspond one-to-one to A2 through A8.

[0289] In item 7, antenna 2 is the main antenna and does not correspond to CF. However, in item 7 of Table 2, antenna 2 is the main antenna and also corresponds to CF. Furthermore, three compensation parameters are determined in item 7. Since the number of compensation parameters is less than the number of first antennas, and the number of first antennas is not an integer multiple of the number of compensation parameters, each compensation parameter can correspond to multiple first antennas. For example, as shown in item 7, CF(1) corresponds to A2, A3, and A8, CF(2) corresponds to A4 and A5, and CF(3) corresponds to A6 and A7.

[0290] In step S2107 , the network device 102 compensates the channel estimation.

[0291] In some embodiments, the network device 102 determines a correspondence between the compensation parameter and the first antenna.

[0292] In some embodiments, the corresponding relationship is agreed upon by protocol.

[0293] In some embodiments, the method by which the network device 102 determines the corresponding relationship is the same as the method by which the terminal determines the corresponding relationship.

[0294] In some embodiments, when the network device 102 uses the SRS to perform channel estimation, the network device 102 uses the compensation parameters to compensate the channel estimation.

[0295] In some embodiments, the network device 102 performs channel estimation compensation on the corresponding first antenna using the compensation parameter.

[0296] In one example, as shown in Table 1, Table 2, Table 3, and Table 4, when antenna 2 corresponds to CF(1), CF(1) is used to perform channel estimation compensation on antenna 2.
