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..." or "when..." or "in response to...".

The embodiments of the present disclosure are described in detail below, and examples of the embodiments 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 cannot be understood as limiting the present disclosure.

As shown in Fig. 1A, the method provided in the embodiment of the present disclosure may 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 the present application does not limit the devices included in the wireless communication system 100.

It should be understood that the above wireless communication system 100 can be applied 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 microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems or future evolved public land mobile network (PLMN) systems, Internet of Things systems, etc.

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 a wireless transceiver function, and it can communicate with one or more network devices of one or more communication systems (such as wireless communication) and receive network services provided by the network devices, where the network devices include but are not limited to the network device 102 shown in the figure.

Among them, 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, a vehicle-mounted device, a wearable device, a terminal in a future 5G network, or a terminal in a future evolved PLMN network, etc.

In the disclosed embodiment, the terminal may be configured to send a sounding reference signal on a receiving antenna to measure a channel condition associated with each receiving antenna. The terminal may have 4 receiving antennas, or may have more than 4 receiving antennas, for example, 8 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 an example, the SRS transmit switching capability may be one of the following:

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

1T4R: The terminal transmits SRS on four antennas in turn, selecting one antenna to transmit at a time.

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

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

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

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

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 different antennas are different.

In one example, as shown in FIG2 , in a 1T4R structure, receiving antenna 2, receiving antenna 3, and receiving antenna 4 correspond to different receiving modules, and main antenna 1 corresponds to the main transceiver module. Compared with main antenna 1, receiving antenna 2, receiving antenna 3, and receiving antenna 4 need to consider the insertion loss of a single-pole double-throw switch and additional line loss. In some protocols, ΔT _RxSRS is used to represent the antenna switching loss.

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 a large estimation error when the network device estimates the channel quality using SRS, thereby affecting the performance of the system.

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

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

Step S2101: the network device 102 sends first configuration information to the terminal 101.

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

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

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

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

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

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

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

In some embodiments, the compensation parameter is a compensation value.

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

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

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.

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.

In some embodiments, the terminal 101 determines the number of compensation parameters to be 1, that is, the terminal 101 determines one compensation parameter.

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

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

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

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.

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 according to the first number and the second number, so a compensation parameter is marked as CF(1).

In one example, the SRS transmission switching capability is 1T4R, so the first number is determined to be 4. 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 3 according to the first number and the second number, so the three compensation parameters are marked as CF(1), CF(2), and CF(3).

In one example, the SRS transmission switching capability is 2T4R, so the first number is determined to be 4. 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 3 according to the first number and the second number, so the three compensation parameters are marked as CF(1), CF(2), and CF(3).

In one example, the SRS transmission switching capability is 2T4R, so the first number is determined to be 4. The number of SRS ports is 2, so the second number is determined to be 2. The number of compensation parameters is determined to be 1 according to the first number and the second number, so the three compensation parameters are marked as CF(1).

In one example, the SRS transmission switching capability is 1T8R, so the first number is determined to be 8. The number of SRS ports is 1, so the first number is determined to be The second number is 1. The number of compensation parameters is determined to be 7 according to the first number and the second number, so that the three compensation parameters are labeled as CF(1) to CF(7).

In one example, the SRS transmission switching capability is 2T8R, so the first number is determined to be 8. 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 7 according to the first number and the second number, so the 7 compensation parameters are marked as CF(1) to CF(7).

In one example, the SRS transmission switching capability is 2T8R, so the first number is determined to be 8. The number of SRS ports is 2, so the second number is determined to be 2. The number of compensation parameters is determined to be 3 according to the first number and the second number, so the three compensation parameters are marked as CF(1), CF(2), and CF(3).

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

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

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

Step S2104: Terminal 101 determines at least one of the first value and the second value.

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

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.

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.

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 the network device to perform compensation during channel estimation.

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

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

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

In some embodiments, the compensation parameter is a compensation value.

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

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.

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.

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

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

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

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

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.

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

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.

Step S2106: the network device 102 determines a first antenna.

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

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

The first method includes:

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 other antennas except the main antenna among the antennas used for sending the SRS, and the number of the main antenna is 1.

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 send the SRS.

In this embodiment, it is considered that the insertion loss caused by the switching between the main antennas can be ignored, 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.

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

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

In one example, when the SRS transmission switching capability is 1T4R, the number of main antennas is 1.

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

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

In some embodiments, the primary antenna has the following capabilities:

Send uplink service data;

Send SRS;

Receive downlink service data.

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

No uplink service data is sent;

Send SRS;

Receive downlink service data.

In some embodiments, the difference between the capabilities of 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.

In an 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.

Table 1

In this example, the terminal 101 has 8 antennas, including A1, A2, ..., A8. A compensation parameter determined by the terminal 101 is denoted as CF. "/" in Table 1 indicates that there is no corresponding CF.

The following is an explanation of Table 1 item by item:

Item 1: The SRS transmission switching capability is 1T2R. The antennas used to send SRS are A1 and A2. A1 is the main antenna and A2 is the diversity antenna. The antennas that need to use compensation parameters are the antennas other than the main antenna used to send SRS, that is, the antenna that needs to use compensation parameters is A2. Therefore, in Item 1, the compensation parameters correspond to A2.

Item 2: The SRS transmission switching capability is 1T4R. The antennas used to send SRS are A1, A2, A3, and A4. A1 is the main antenna, and A2, A3, and A4 are diversity antennas. The antennas that need to use compensation parameters are the antennas other than the main antenna used to send SRS, that is, the antennas that need to use compensation parameters are A2, A3, and A4. Therefore, in Item 2, the compensation parameters correspond to A2, A3, and A4.

Item 3: The SRS transmission switching capability is 2T4R, and the number of SRS ports is 1. The antennas used to send SRS are A1, A2, A3, and A4. A1 and A2 are main antennas, and A3 and A4 are diversity antennas. The antennas that need to use compensation parameters are the antennas other than the main antenna used to send SRS, that is, the antennas that need to use compensation parameters are A3 and A4. Therefore, in Item 3, the compensation parameters correspond to A3 and A4.

Item 4: The SRS transmission switching capability is 1T8R, and the number of SRS ports is 1. The antennas used to send SRS are A1 to A8. A1 is the main antenna, and A2 to A8 are diversity antennas. The antennas that need to use compensation parameters are the antennas other than the main antenna used to send SRS, that is, the antennas that need to use compensation parameters are A2 to A8. Therefore, in Item 5, the compensation parameters correspond to A2 to A8.

Item 5: The SRS transmission switching capability is 2T8R, and the number of SRS ports is 1. The antennas used to send SRS are A1 to A8. A1 and A2 are main antennas, and A3 to A8 are diversity antennas. The antennas that need to use compensation parameters are the antennas other than the main antenna used to send SRS, that is, the antennas that need to use compensation parameters are A3 to A8. Therefore, in Item 6, the compensation parameters correspond to A3 to A8.

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

The second method includes:

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 other antennas except the main antenna among the antennas used for sending the SRS, and the number of the main antenna is 1.

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 used for sending the SRS except the reference antenna.

In this embodiment, it is considered necessary to consider the impact of insertion loss caused by switching between main antennas, so 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.

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

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

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

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

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

In one example, when the SRS transmission switching capability is 1T4R, the number of main antennas is 1.

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

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

In some embodiments, the primary antenna has the following capabilities:

Send uplink service data;

Send SRS;

Receive downlink service data.

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

No uplink service data is sent;

Send SRS;

Receive downlink service data.

In some embodiments, the difference between the capabilities of 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.

In an 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 method when having different SRS transmission switching capabilities.

Table 2

In this example, the terminal 101 has 8 antennas, including A1, A2, ..., A8. A compensation parameter determined by the terminal 101 is denoted as CF. "/" in Table 1 indicates that there is no corresponding CF.

The following explains the difference between Table 2 and Table 1:

The difference between Table 2 and Table 1 lies in the 3rd and 5th items.

When the number of transmitting antennas in the SRS transmission switching capability of the terminal 101 is greater than 1, the first antenna in Table 1 is the antenna used to transmit the SRS except the main antenna, that is, CF does not correspond to any main antenna, and the first antenna in Table 2 is the antenna used to transmit the SRS except the reference antenna, that is, CF corresponds to the main antenna except the reference antenna. Therefore, the difference between Table 2 and Table 1 lies in the third and fifth items.

In item 3 in Table 1, antenna 2 is the main antenna and does not correspond to CF, while in item 3 in Table 2, antenna 2 is the main antenna and also corresponds to CF.

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.

In an example, Table 3 is combined 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 there are different SRS transmission switching capabilities.

Table 3

In Table 3, the method for 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.

The following is an explanation of Table 3 item by item:

Item 1:

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

Determine the first antenna: The SRS transmission switching capability is 1T2R, so the antennas used to send SRS are determined to be A1 and A2. A1 is the main antenna, and A2 is the diversity antenna. The antennas that need to use compensation parameters are the antennas used to send SRS except the main antenna, that is, the first antenna is A2.

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

Item 2:

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

Determine the first antenna: The SRS transmission switching capability is 1T4R, so the antennas used to send SRS are determined to be A1, A2, A3 and A4. A1 is the main antenna, and A2, A3 and A4 are diversity antennas. The antennas that need to use compensation parameters are the antennas used to send SRS except the main antenna, that is, the first antennas are A2, A3 and A4.

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 in a sequential correspondence manner, that is, one-to-one correspondence is performed according to the arrangement order of the multiple compensation coefficients and the arrangement order of the antenna serial number 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.

Item 3:

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

Determine the first antenna: The SRS transmission switching capability is 2T4R, so the antennas used to send SRS are determined to be A1, A2, A3 and A4. A1 and A2 are main antennas, and A3 and A4 are diversity antennas. The antennas that need to use compensation parameters are the antennas used to send SRS except the main antenna, that is, the first antennas are A3 and A4.

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 in the plurality of compensation parameters may correspond to the plurality of first antennas in sequence, and the arrangement order of the partial compensation coefficients in the plurality of compensation coefficients and the arrangement order of the antenna serial number of the first antenna are one-to-one corresponded, wherein the number of partial 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.

Item 4:

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

Determine the first antenna: The SRS transmission switching capability is 2T4R, so the antennas used to send SRS are determined to be A1, A2, A3 and A4. A1 and A2 are main antennas, and A3 and A4 are diversity antennas. The antennas that need to use compensation parameters are the antennas used to send SRS except the main antenna, that is, the first antennas are A3 and A4.

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

Item 5:

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

Determine the first antenna: The SRS transmission switching capability is 1T8R, so the antennas used to send SRS are determined to be A1 to A8. A1 is the main antenna, and A2 to A8 are diversity antennas. The antennas that need to use compensation parameters are the antennas used to send SRS except the main antenna, that is, the first antennas are A2 to A8.

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 in a sequential correspondence manner, that is, one-to-one correspondence is performed according to the arrangement order of the multiple compensation coefficients and the arrangement order of the antenna serial number 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.

Item 6:

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

Determine the first antenna: The SRS transmission switching capability is 2T8R, so the antennas used to send SRS are determined to be A1 to A8. A1 and A2 are main antennas, and A3 to A8 are diversity antennas. The antennas that need to use compensation parameters are the antennas used to send SRS except the main antenna. The antennas, namely the first antenna, are A3 to A8.

Thus, 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 in the plurality of compensation parameters may correspond to the plurality of first antennas in sequence, and the arrangement order of the partial compensation coefficients in the plurality of compensation coefficients and the arrangement order of the antenna serial number of the first antenna are one-to-one corresponded, wherein the number of partial 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…CF(6) corresponds to A7.

Item 7:

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

Determine the first antenna: The SRS transmission switching capability is 2T8R, so the antennas used to send SRS are determined to be A1 to A8. A1 and A2 are main antennas, and A3 to A8 are diversity antennas. The antennas that need to use compensation parameters are the antennas other than the main antenna in the antennas used to send SRS, that is, the first antennas are A3 to A8.

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.

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.

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

The first method includes:

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 other antennas except the main antenna among the antennas used for sending the SRS, and the number of the main antenna is 1.

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 used for sending the SRS except the reference antenna.

In an example, Table 4 is combined 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 there are different SRS transmission switching capabilities.

Table 4

The following explains the difference between Table 4 and Table 3:

The difference between Table 4 and Table 3 lies in the 3rd and 5th items.

Since the number of transmitting antennas in the SRS transmission switching capability of the terminal 101 is greater than 1, the first antenna in Table 1 is the antenna used to transmit the SRS except the main antenna, that is, CF does not correspond to any main antenna, and the first antenna in Table 2 is the antenna used to transmit the SRS except the reference antenna, that is, CF corresponds to the main antenna except the reference antenna. Therefore, the difference between Table 2 and Table 1 lies in the 3rd, 4th, 6th and 7th items.

In item 3, antenna 2 is the main antenna and does not correspond to CF, while in item 3 in Table 2, antenna 2 is the main antenna and also corresponds to CF. And 3 compensation parameters are determined in item 3, so the 3 compensation parameters correspond to A2, A3 and A4 one by one.

In item 4, antenna 2 is the main antenna and does not correspond to CF, while in item 4 in Table 2, antenna 2 is the main antenna and also corresponds to CF. And only one compensation parameter is determined in item 4, so the one compensation parameter corresponds to A2, A3 and A4.

In item 6, antenna 2 is the main antenna and does not correspond to CF, while in item 6 in Table 2, antenna 2 is the main antenna and also corresponds to CF. And 7 compensation parameters are determined in item 6, so the 7 compensation parameters correspond to A2 to A8 one by one.

In item 7, antenna 2 is the main antenna and does not correspond to CF, while in item 7 of Table 2, antenna 2 is the main antenna and also corresponds to CF. And 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, such 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.

Step S2107: the network device 102 compensates for the channel estimation.

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

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

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.

In some embodiments, when the network device 102 uses the SRS to perform channel estimation, the network device 102 uses the compensation parameter to compensate the channel estimation.

In some embodiments, the network device 102 uses the compensation parameter to perform channel estimation compensation on the corresponding first antenna.

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.
