Technical Field

Background

In the mobility scenario of the terminal device, the channels of the terminal device at different moments may change drastically, so that the performance is reduced, i.e. the "channel aging" problem. To avoid performance degradation, the terminal device may feed back channel time domain related information to the network device in combination with downlink channel measurement information (e.g., channel state information reference signal (CHANNEL STATE information REFERENCE SIGNAL, CSI-RS), tracking reference signal (TRACKING REFERENCE SIGNAL, TRS)) of multiple times or multiple OFDM symbols. The channel time domain related information can indicate the time variation of the channel or the time variation speed of the channel, and the network equipment can correspondingly and dynamically adjust the configuration of the downlink reference signal or the downlink precoding mode based on the channel time domain related information, so that the current terminal equipment is better served.

In the related technical scheme, in the process of calculating the channel time domain related information, the receiving mode of an antenna port of the terminal equipment is not considered, so that the accuracy of the calculated channel time domain related information is poor, the configuration or decision of the network equipment is affected, and the performance is reduced.

In the embodiment of the application, the network device can be any device with a wireless receiving and transmitting function.

The DUs are responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (radio link control, RLC), medium access control (medium access control, MAC) and Physical (PHY) layers. The AAU realizes part of physical layer processing function, radio frequency processing and related functions of the active antenna. Since the information of the RRC layer may eventually become information of the PHY layer or be converted from the information of the PHY layer, under this architecture, higher layer signaling, such as RRC layer signaling, may also be considered to be transmitted by DUs or by DUs and CUs. It is understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into network devices in an access network (radio access network, RAN), or may be divided into network devices in a Core Network (CN), which the present application is not limited to.

Network device 110 and terminal device 120 may communicate via a wireless link. Each communication device, such as network device 110 or terminal device 120, may be configured with multiple antennas. For each communication device in the communication system, the plurality of antennas configured may include at least one transmit antenna for transmitting signals and at least one receive antenna for receiving signals. Therefore, communication can be performed between the communication devices in the communication system, between the network device 110 and the terminal device 120, by using a multi-antenna technology.

It should be understood that fig. 1 is a simplified schematic diagram for ease of understanding only, and that other network devices or other terminal devices may be included in the communication system, which are not shown in fig. 1.

The architecture to which the embodiment of the present application shown in fig. 1 can be applied is merely an example, and the architecture to which the embodiment of the present application is applied is not limited to this, and any architecture capable of implementing the functions of the respective devices is applicable to the embodiment of the present application.

It should also be understood that the above designations are merely intended to facilitate distinguishing between different functions and should not be construed as limiting the application in any way. The application does not exclude the possibility of using other designations in 5G networks as well as in other networks in the future. For example, in a 6G network, some or all of the above devices may follow the terminology in 5G, other names may also be used, etc. The names of interfaces between the devices in fig. 1 are only an example, and the names of interfaces in the specific implementation may be other names, which are not specifically limited by the present application. Furthermore, the names of the transmitted messages (or signaling) between the above-described respective devices are also merely an example, and do not constitute any limitation on the functions of the messages themselves.

In order to improve the signal transmission quality or rate, the network device needs to perform channel estimation on the wireless channel before transmitting data to the terminal device. The network device may perform channel estimation according to a Sounding REFERENCE SIGNAL (SRS) from the terminal device, to obtain uplink channel state information (CHANNEL STATE information, CSI), where the channel state information characterizes a state of a channel at a time point (time point 1) when the network device receives the reference signal. In a time division multiplexing (time division duplexing, TDD) system, uplink and downlink of a wireless channel have interoperability, so in a channel estimation process, a network device obtains downlink CSI according to the uplink CSI, calculates downlink precoding used for data transmission by using the downlink CSI, and uses the downlink precoding (at time 2) to transmit data to a terminal device.

It will be appreciated that the signal from the transmitting end to the receiving end over the wireless channel may experience fading due to scattering, reflection and attenuation of energy with distance. CSI is used to characterize a wireless channel and may include at least one of a precoding matrix indicator (pre-coding matrix indicator, PMI), a channel quality indicator (channel quantity indicator, CQI), a CSI-RS resource indicator (CSI-RS resource indicator, CRI), a synchronization signal and physical broadcast channel block (SSB) resource indicator (SSB resource indicator, SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), a reference signal received power (REFERENCE SIGNAL RECEIVED power, RSRP), and a signal-to-interference-and-noise ratio (signal to interference plus noise ratio, SINR). The CSI may be transmitted by the terminal device to the network device through a physical uplink control channel (physical uplink control channel, PUCCH) or a Physical Uplink Shared Channel (PUSCH) SHARE CHANNEL.

Because of the time delay between the time 1 and the time 2, in the mobility scenario of the terminal device, the channel of the terminal device at the time 2 may have been changed drastically compared with the time 1, which results in the mismatch between the downlink precoding and the channel of the terminal device at the time 2, so that the performance is reduced, i.e. the "channel aging" problem.

To avoid performance degradation, the terminal device may combine downlink channel measurement information (e.g., channel state information reference signal (CHANNEL STATE information REFERENCE SIGNAL, CSI-RS), tracking reference signal (TRACKING REFERENCE SIGNAL, TRS)) at multiple times to feed back channel time domain related information to the network device. On the one hand, the network device can utilize the channel at the moment 1, the channel obtained by a plurality of reference signals before the moment 1 and the channel at the moment 2 according to the channel time domain related information, so that the problem of performance degradation caused by channel aging is solved, and the performance is improved. On the other hand, the channel time domain related information fed back by the terminal equipment can also help the network equipment to configure the downlink reference signals, so that the terminal equipment is better served, and the performance is improved.

It should be appreciated that the channel time domain related information can indicate a time-dependent change or a time-dependent change of the channel, for example, in a case that the network device determines that the current terminal device channel is very fast in time-dependent change (typically, the terminal device is being moved at a high speed), the network device dynamically adjusts the configuration or precoding manner of the downlink reference signal or the uplink feedback channel of the terminal device accordingly, so as to better serve the current terminal device.

Therefore, in order to make the network device better serve the terminal device, the accuracy of reporting the channel time domain related information to the network device by the terminal device is particularly important.

In the related technical scheme, channel time domain related information is calculated through the following formula.

Or (b)

Where n represents the number of subcarriers;

H _n (t) represents the channel CSI for time t or OFDM symbol sub-carriers;

H _n (t+τ) represents the channel CSI for the time t+τ or for the OFDM symbol subcarriers;

a (t, τ) is channel time domain related information, and represents intensity of channel change with time in a time period from time t or OFDM symbol to time t+τ or OFDM symbol.

In the process of calculating the channel time domain related information, the receiving mode of the antenna port of the terminal equipment is not considered, so that the accuracy of the calculated channel time domain related information is poor, the configuration of the downlink reference signal or the determination of the precoding mode or the channel prediction of the network equipment is affected, and the performance is reduced.

In view of this, the embodiment of the application provides an information processing method, which can consider the receiving mode of the antenna port of the terminal device in the process of calculating the channel time domain related information by the terminal device, so as to improve the accuracy of the channel time domain related information. It should be understood that the antenna port may also be a port, an antenna, a receiving port, a receiving antenna.

A method for processing information according to an embodiment of the present application will be described in detail with reference to fig. 2 to 3. It should be understood that the methods of fig. 2-3 may be performed by the terminal device or may be performed by a chip having the functionality of the terminal device.

Fig. 2 is a schematic flow chart of a method for information processing according to an embodiment of the present application. As shown in FIG. 2, the method may include steps 210-220, with steps 210-220 being described in detail below, respectively.

Step 210: and respectively determining at least two groups of channel time domain related information according to at least two groups of antenna ports of the terminal equipment.

In the embodiment of the application, a plurality of antenna ports of the terminal equipment can be divided into at least two groups, and each group can comprise at least one antenna port. For each set of antenna ports, a set of channel time domain related information may be fed back, i.e. for at least two sets of antenna ports of the terminal device, at least two sets of channel time domain related information may be generated or determined, each set of channel time domain related information corresponding to each set of antenna ports one to one.

The above-mentioned time domain related information of each set of channels may include M time domain related information of channels corresponding to a plurality of T times or T orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols, where the M time domain related information of channels is used to indicate correlation between channels of the T times or T OFDM symbols.

It should be understood that there are various ways how the plurality of antenna ports of the terminal device are grouped (i.e. how the plurality of antenna ports of the terminal device are divided into at least two groups described above), and embodiments of the present application are not limited in particular. In one possible implementation, it may be that the terminal device determines a grouping mode and feeds back the grouping mode to the network device. In another possible implementation manner, the network device may also notify the terminal device of the corresponding packet. In another possible implementation manner, the terminal device and the network device may determine a grouping manner of a plurality of antenna ports of the terminal device in advance.

In some embodiments, for each set of antenna ports a set of channel time domain related information is determined, where more than one antenna port is included in a set, it may be determined from at least two antenna ports included in the set of antenna ports. The following will be described in detail with reference to specific formulas, and will not be repeated here.

Step 220: and transmitting the at least two sets of channel time domain related information or one set of channel time domain related information to the network equipment.

In the embodiment of the present application, the terminal device may send the determined at least two sets of channel time domain related information to the network device, or may also send a set of channel time domain related information determined according to the at least two sets of channel time domain related information to the network device, which is not specifically limited in the embodiment of the present application.

In one example, if the terminal device sends a set of channel time domain related information to the network device, the terminal device further needs to determine a set of channel time domain related information according to at least two sets of channel time domain related information. The specific implementation manner is various, and in one possible implementation manner, the terminal device may select a set of channel time domain related information from at least two sets of channel time domain related information as the set of channel time domain related information according to the confidence corresponding to the at least two sets of channel time domain related information. In a possible implementation manner, the terminal device may perform weighted average on at least two sets of channel time domain related information according to the confidence degrees corresponding to the at least two sets of channel time domain related information, so as to obtain the set of channel time domain related information. In a possible implementation manner, the terminal device may calculate an arithmetic average of at least two sets of channel time domain related information according to the sets of channel time domain related information to obtain the sets of channel time domain related information.

As another example, if the terminal device sends at least two sets of channel time domain related information to the network device. In a possible implementation manner, the network device may calculate an arithmetic average of at least two sets of channel time domain related information according to the sets of channel time domain related information to obtain the sets of channel time domain related information. The terminal device may also send at least two confidence information corresponding to the at least two sets of channel time domain related information respectively to the network device. The network device may determine a set of channel time domain related information based on the at least two sets of channel time domain related information and the corresponding confidence levels. The network device may select, according to the confidence levels corresponding to the at least two sets of channel time domain related information, a set of channel time domain related information with the highest confidence level from the at least two sets of channel time domain related information as the set of channel time domain related information. In another possible implementation manner, the network device may perform weighted average on the at least two sets of channel time domain related information according to the confidence degrees corresponding to the at least two sets of channel time domain related information, so as to obtain the set of channel time domain related information.

In the above technical solution, at least two sets of channel time domain related information may be fed back to the network device based on at least two sets of antenna ports of the terminal device, respectively, or a set of channel time domain related information determined according to the at least two sets of signal antenna ports. Different antenna ports of the terminal equipment can obtain different channel time domain related information due to different receiving channel power or signal to noise ratio or random phase noise and diversity of arrangement positions of the antenna ports of the terminal equipment, so that at least two groups of channel time domain related information corresponding to at least two groups of antenna ports are fed back to the network equipment, or a group of channel time domain related information determined according to the at least two groups of channel time domain related information is fed back to the network equipment, and therefore accuracy of the channel time domain related information fed back to the network equipment by the terminal equipment can be improved, and change characteristics of channels along with time can be reflected more accurately.

Fig. 3 is a schematic flow chart of another information processing method provided by an embodiment of the present application. As shown in FIG. 3, the method may include steps 310-320, with steps 310-320 being described in detail below, respectively.

Step 310: and determining a group of channel time domain related information according to the channel time domain related information respectively corresponding to at least two antenna ports of the terminal equipment.

In the embodiment of the application, a group of channel time domain related information can be determined according to the channel time domain related information respectively corresponding to at least two antenna ports of the terminal equipment, wherein the group of channel time domain related information comprises M channel time domain related information respectively corresponding to T moments or T OFDM symbols. Each channel time domain correlation information is determined according to at least two antenna ports, and M channel time domain correlation information is used to indicate correlation between channels of T times or T OFDM symbols.

Step 320: a set of channel time domain related information is transmitted to a network device.

After obtaining the set of channel time domain related information, the terminal device may send the set of channel time domain related information to the network device.

In the above technical solution, each channel time domain related information in a set of channel time domain related information fed back by the terminal device to the network device is determined according to channels corresponding to at least two antenna ports by joint average, that is, the channel time domain related information corresponding to at least two antenna ports of the terminal device is considered, which is equivalent to the average among different antenna ports of the terminal device when each channel time domain related information is calculated, so that the number of samples calculated by each channel time domain related information is increased, thereby realizing the function of reducing noise of calculation of each channel time domain related information, improving the accuracy of the channel time domain related information fed back to the network device by the terminal device, and thus more accurately reflecting the change characteristics of the channel along with time.

The specific implementation of the method shown in fig. 2-3 will be illustrated with reference to fig. 4-6 by taking the example that the terminal device has N _r antenna ports, the network device transmits TRS or CSI-RS, the terminal device can obtain channels of N total subcarriers, and the terminal device reports the time domain related information (for example, the time domain related coefficient or the amplitude of the time domain related coefficient) of the channel of the M time intervals or time differences or OFDM symbol intervals of τ ₁,τ₂,…,τ_M.

It should be appreciated that the examples of fig. 4-6 are merely intended to aid one skilled in the art in understanding embodiments of the present application and are not intended to limit application embodiments to the specific values or particular scenarios illustrated. Various equivalent modifications and variations will be apparent to those skilled in the art from the examples of fig. 4-6 given below, and such modifications and variations are intended to be within the scope of embodiments of the present application.

In one example, corresponding to step 310, the terminal device determines a set of channel time domain related information R _1*M＝{R(τ₁),R(τ₂),…,R(τ_M according to a joint average of channel time domain related information corresponding to at least two antenna ports of the terminal device. Wherein R _1*M is a set of channel time domain related information, which includes M channel time domain related information, and R is R (τ ₁),R(τ₂),…,R(τ_M),τ₁,τ₂,…,τ_M is M time intervals or time differences or OFDM symbol intervals, respectively).

For example, with R (τ ₁),R(τ₂),…,R(τ_M) being the magnitude of the time domain correlation coefficient, the embodiment of the present application can calculate R (τ _i) by the following formula.

Or (b)

Wherein R (τ _i) represents the intensity of the channel (channel time domain related information) over time in the time period from time t to time t+τ _i or OFDM symbol t to OFDM symbol t+τ _i;

h _k,n (t) represents channel information of a subcarrier n corresponding to an antenna port k of the terminal equipment at a time t or an OFDM symbol t;

h _k,n(t+τ_i) represents channel information of the subcarrier n corresponding to the antenna port k of the terminal equipment at the time t+τ _i or the OFDM symbol t+τ _i;

Considering that the antenna ports of the terminal may have different receiving phase noise, the embodiment of the present application may also be calculated by the following formula:

Or (b)

As another example, taking R (τ ₁),R(τ₂),…,R(τ_M) as the time domain correlation coefficient, the embodiment of the present application can calculate R (τ _i) according to the following formula.

Or (b)

It should be appreciated that h _k,n (t) above may be obtained by the terminal device through a TRS or CSI-RS signal sent by the network device at time t, and h _k,n(t+τ_i) above may be obtained by the terminal device through a TRS or CSI-RS signal sent by the network device at time t+τ _i.

For example, as shown in fig. 4, taking N _r =4 as an example, assuming that the terminal device has 4 antenna ports, R (τ ₁) indicates the intensity of the channel change (channel time domain related information) with time in the period from time t to time t+τ ₁, where R (τ ₁) is the joint average of the channel time domain related information of the 4 antenna ports of h ₁～h₄ of the terminal device. In other words, the implementation mode performs "series connection" on the channel vectors of different antenna ports (h ₁～h₄) of the terminal equipment, expands the channel of a single port into a multi-port channel, and improves the original correlation of N samples to n×n _r samples to calculate the correlation, which is equivalent to performing averaging among different antenna ports when calculating the time domain correlation information of the channel, thereby realizing the function of noise reduction. Concatenating N _r ports, equivalent to signal-to-noise ratio (signal noise ratio, SNR), improves δ=10log ₁₀N_r dB.

Another example, corresponding to step 210, takes the terminal device to determine at least two sets of channel time domain related information according to the channel time domain related information corresponding to at least two sets of antenna ports of the terminal device as an example.

In the case that each group of antenna ports comprises one antenna port, it is also understood that the channel vectors of the different antenna ports of the terminal device are "parallel". In this implementation, the terminal device may feed back a channel time domain related information matrix to the network deviceThat is, each antenna port of the terminal device feeds back the corresponding channel time domain related information, and feeds back N _r sets of channel time domain related information in total.

For example, with each element r _k,m in the N _r sets of channel time domain related information as the amplitude of the time domain related coefficient, the embodiment of the present application can calculate r _k,m according to the following formula.

Or

Where k=1, 2, …, N _r, m=1, 2, …, M.

For another example, r _k,m may be calculated by using each element r _k,m in the N _r sets of channel time domain correlation information as a time domain correlation coefficient according to the embodiment of the present application.

Or

For example, as shown in fig. 5, taking N _r =4 as an example, it is assumed that the terminal device has 4 antenna ports, each antenna port may feed back one set of channel time domain related information, and 4 antenna ports may feed back 4 sets of channel time domain related information. That is, the implementation mode carries out parallel connection on the channel vectors of different antenna ports (h ₁～h₄) of the terminal equipment, and each antenna port feeds back corresponding channel time domain related information.

The feedback mode of the channel time domain related information of the parallel connection of the antenna ports of the terminal equipment considers that different channel time domain related information can be obtained by the channels of different antenna ports due to the antenna arrangement of the terminal equipment, thereby improving the performance.

In another case, each set of antenna ports includes at least two antenna ports. It is assumed that a plurality of antenna ports of the terminal device are divided into G groups, where the G group includes N _g antenna ports, and each group of antenna ports feeds back a set of channel time domain related information. In this implementation, the terminal device may feed back a channel time domain related information matrix to the network deviceI.e. a total feedback of the G-group channel time domain related information.

For example, with each element r _g,m in the time domain correlation information of the G group channel as the amplitude of the time domain correlation coefficient, the embodiment of the present application can calculate r _g,m according to the following formula.

Or (b)

Where g=1, 2, …, G, m=1, 2, …, M.

Considering that the antenna ports of the terminals in the unified group may have different receiving phase noise, the embodiment of the present application may also calculate by the following formula:

Or (b)

For another example, r _g,m may be calculated by using each element r _g,m in the N _r sets of channel time domain correlation information as a time domain correlation coefficient according to the embodiment of the present application.

Or (b)

For example, as shown in fig. 6, N _r＝4,G＝2,N₁＝N₂ =2 is taken as an example. Assuming that the terminal device has 4 antenna ports, the 4 antenna ports are divided into 2 groups, each group of antenna ports includes 2 antenna ports (the first group of antenna ports includes an antenna port h ₁～h₂ and the second group of antenna ports includes an antenna port h ₃～h₄), and the 2 groups of antenna ports can feed back 2 groups of channel time domain related information. For 2 antenna ports in 1 group, the channel time domain related information of 1 group can be determined according to the channel time domain related information corresponding to the 2 antenna ports in a joint average manner. That is, the implementation "parallels" the channel vectors of the 2 groups of antenna ports of the terminal device, while the channel vectors of the 2 antenna ports within each group are "in series".

It should be noted that, the manner of "connecting in series" the plurality of antenna port channels of the terminal device may be understood as a special form of g=1, and the manner of "connecting in parallel" the plurality of antenna port channels of the terminal device may be understood as a special form of g=n _r.

As described above, two different information processing methods are shown in fig. 2 and 3, and as shown in fig. 2, the terminal device may feed back at least two sets of channel time domain related information to the network device or feed back a set of channel time domain related information determined according to the at least two sets of channel time domain related information, and as shown in fig. 3, the terminal device feeds back a set of channel time domain related information to the network device. The embodiment of the application can also characterize the confidence coefficient of the channel time domain related information through the confidence coefficient information. Several possible implementations are listed below.

In one possible implementation, the confidence level of a set of channel time domain related information may be characterized by a confidence level information. For example, for at least two sets of channel time domain related information fed back by the terminal device to the network device in fig. 2, the confidence level of the at least two sets of channel time domain related information may be respectively represented by at least two sets of confidence level information, where each set of confidence level information corresponds to each set of channel time domain related information one by one, and is respectively used to represent the confidence level of the corresponding set of channel time domain related information. As another example, for a set of channel time domain related information that the terminal device feeds back to the network device in fig. 2 or fig. 3, the confidence of the set of channel time domain related information may be characterized by a confidence information.

For ease of description, the following is exemplified by the confidence that at least two sets of channel time domain related information are respectively characterized by at least two pieces of confidence information.

As an example, G pieces of confidence information, which are used to characterize the confidence of the G sets of channel time domain related information, respectively, are represented by G pieces of parameters w= { W ₁,w₂,…,w_G }. For example, confidence information w _g of the G confidence information is used to characterize the confidence of the G-th set of channel time domain related information.

It should be understood that the above confidence information may be determined in various manners, and embodiments of the present application are not limited thereto. For ease of description, several different ways of determining the confidence information described above are illustrated below by way of example of confidence information w _g.

In example 1, w _g may be a sum of powers of channels corresponding to the g-th group of antenna ports. For example, w _g may be determined according to the formula shown below.

Or

Where τ ₀ =0.

In example 2, w _g may be the sum of normalized power values normalized to maximum power. For example, w _g may be determined according to the formula shown below, where the g _m th group of antenna ports corresponds to the maximum power sum.

Or

In example 5, w _g may be a received signal-to-noise ratio of a channel corresponding to the g-th group of antenna ports. For example, w _g may be determined according to the formula shown below.

Example 6, the w _g may be the absolute value of the difference from the maximum signal-to-noise ratio. For example, w _g may be determined according to the formula shown below, i.e., the g _m group antenna port corresponds to the maximum signal-to-noise ratio.

In example 8, w _g may be a signal-to-noise ratio of time domain related information corresponding to the g-th group of antenna ports. For example, w _g may be determined according to the formula shown below.

Or (b)

Wherein, τ ₀ =0,The noise power corresponding to the channel of the OFDM symbol at the time t+τ _i or the time t+τ _i of the g group antenna port.

It should be noted that, for example 2, example 4, example 6 and example 7 described above, namelyIn case of a difference from the physical meaning of the other w _g feedback, the pairQuantization is performed using L ₁ bits, and w _g is quantized using L ₂≤L₁ bits. G _m,/>, can also be fed backAnd G-1 parameters w ₁,w₂,…,w_g,…,w_G, where g+.g _m.

It should be appreciated that for the examples 5,6,7 above, the terminal device and the network device also need to align the number of antenna ports that obtain each set of time domain related information. There are a variety of specific implementations, and embodiments of the present application are not limited in this regard. In a possible implementation manner, the terminal device may determine the number N _g of antenna ports of each set of time domain related information, and feed back the information to the network device. In another possible implementation, the network device may also notify the terminal device of the information. In another possible implementation, the information may also be predetermined by the terminal device and the network device.

In another possible implementation, the confidence level of a channel time domain related information may also be characterized by a confidence level information. For example, for a set of channel time domain related information fed back by the terminal device to the network device in fig. 2 or fig. 3, the confidence level of at least one channel time domain related information in the set of channel time domain related information may be characterized by at least one confidence level information. For another example, for at least two sets of channel time domain related information fed back to the network device by the terminal device in fig. 2, it is assumed that G sets of channel time domain related information are fed back to the network device, where each set of channel time domain related information includes M channel time domain related information, and in the embodiment of the present application, confidence degrees of the g×m channel time domain related information may be respectively represented by g×m parameters w= { W _gm }.

For convenience of description, the following is exemplified by the confidence that the terminal device characterizes the time domain related information of the g×m channels by the g×m parameters w= { W _gm } respectively, where W _gm is used to characterize the confidence of the time domain related information of the M th channel of the G-th group of antenna ports.

It should be understood that the above confidence information may be determined in various manners, and embodiments of the present application are not limited thereto. For ease of description, several different ways of determining the confidence information described above are illustrated below by way of example of confidence information w _gm.

Wherein,For the noise power corresponding to the channel of the antenna port t time or the t OFDM symbol of the g group,The noise power corresponding to the channel of the OFDM symbol at the time t+τ _m or the time t+τ _m of the g group antenna port.

In another possible implementation, the confidence level of the channel of a group of antenna ports at time t or OFDM symbol t may also be characterized by a confidence level information. For example, the terminal device may determine that g×t parameters w= { W _gt},w_gt are used to characterize the confidence of the channel at time T or OFDM symbol T of the G-th group of antenna ports. There are various ways of specifically determining w _gt, and several possible implementations are listed below.

In example 1, w _gt may be a sum of powers of channels corresponding to the time t of the antenna port t of the g-th group or the OFDM symbol t. For example, w _gt may be determined according to the formula shown below.

In example 2, w _gt may be a sum of normalized power values obtained by normalizing power of a channel corresponding to the t-th group antenna port t time or the t-th OFDM symbol to a maximum power. For example, w _gt may be determined according to the formula shown below.

In some embodiments, after the terminal device obtains the G confidence degrees or the G x M confidence degrees or the G x T confidence degrees by using the above method, in one implementation manner, the terminal device may determine the confidence degrees corresponding to each set of channel time domain related information, determine a set of channel time domain related information based on the confidence degrees corresponding to each set of channel time domain related information as a final result, and feed back the final result to the network device. In another implementation manner, the terminal device may directly send the G confidence degrees or the g×m confidence degrees or the g×t confidence degrees to the network device, and the network device may determine the confidence degrees corresponding to each set of channel time domain related information, and determine a set of channel time domain related information as a final result based on the confidence degrees corresponding to each set of channel time domain related information.

Taking the example that the terminal device determines a set of channel time domain related information based on the confidence coefficient corresponding to each set of channel time domain related information as a final result, in one implementation manner, the terminal device may select, as the final result, a set with highest confidence coefficient from multiple sets of channel time domain related information based on the confidence coefficient corresponding to each set of channel time domain related information. In another implementation manner, the terminal device may combine multiple sets of channel time domain related information based on the confidence corresponding to each set of channel time domain related information, so as to obtain a set of channel time domain related information as a final result. For example, one possible way of combining may be to weight average the sets of channel time domain related information by confidence information to obtain a set of channel time domain related information.

Optionally, in some embodiments, in order to reduce the feedback overhead of the channel time domain related information, the terminal device may further normalize the channel time domain related information, thereby reducing the feedback overhead. The terminal equipment feeds back a group of time domain related information of the channel with the length of M to the network equipment: r (τ ₁),R(τ₂),…,R(τ_M) is an example, and several possible implementations of further normalization of the channel time domain related information are described in detail.

As an example, the minimum time interval or time difference or OFDM symbol interval corresponds to the case of maximum channel time domain related information. As shown in fig. 7, the general channel time domain related information decreases as the time interval or time difference or OFDM symbol interval increases, and if τ ₁ is the minimum time interval or time difference or OFDM symbol interval, R (τ ₁) corresponding to τ ₁ is the largest value of R (τ ₁),R(τ₂),…,R(τ_M).

It should be noted that R (τ ₁) may be quantized using L ₁ bits,L ₂≤L₁ bits may be used for quantization.

As another example, the minimum time interval or time difference or OFDM symbol interval does not correspond to the case of maximum channel time domain related information. As shown in fig. 8, τ ₁ is the minimum time interval or time difference or OFDM symbol interval, R (τ ₁) corresponding to τ ₁ is not the largest value of R (τ ₁),R(τ₂),…,R(τ_M), and R (τ _flag) corresponding to τ _flag is the largest value of R (τ ₁),R(τ₂),…,R(τ_M). In the embodiment of the application, R (tau ₁),R(τ₂),…,R(τ_m),…,R(τ_M) can be further normalized by R (tau _flag), and the obtained normalization result is thatThe terminal device can feed back R (τ _flag),τ_flag＝argmax_τ R (τ) and normalization result to the network deviceτ_m≠τ_flag。

It should be noted that R (τ _flag) may be quantized using L ₁ bits,L ₂≤L₁ bits may be used for quantization.

In one possible implementation, L bit pairs R (τ _tlag) or normalized may be used in a uniform quantization mannerQuantization is performed. Specifically, [0,1] can be divided intoOrThese 2 ^L values find the R (τ _flag) to be quantified or normalizedAndOrThe nearest one of the valuesAccording toThe corresponding L bits get their quantization results. One possible implementation is an L-bit binary form corresponding to I or I-1 as quantized L bits.

In another possible implementation, L bit pairs R (τ _flag) or normalized may be used in a non-uniform quantization mannerQuantization is performed. Specifically, [0,1] can be divided into 2 ⁰,2^-1,…,2^-(L-1) or 2 ^-1,2^-2,…,2^-L, which are 2 ^L values. I.e. find R (τ _flag) to be quantified or normalizedThe most recent one of the values 2 ^-I, 2 ⁰,2^-1,…,2^-(L-1) or 2 ^-1,2^-2,…,2^-L, yields its quantization result from the corresponding L bits of 2 ^-I, respectively.
