Technical field

This application relates to the field of communications, and more specifically, to a method for receiving instructions, a method for sending instructions, and a communication device.

Background technique

In some communication systems, such as the 5th generation (5G) communication system, there are higher requirements for system capacity and spectrum efficiency. In 5G communication systems, massive multiple-input multiple output (massive multiple-input multiple output, Massive MIMO) technology plays a vital role in the spectrum efficiency of the system.

When a massive multiple-input multiple output (MIMO) technology is adopted, when a network device sends data to a terminal device, modulation coding and signal precoding are required. How the network device sends data to the terminal device depends on the channel state information (CSI) that the terminal device feeds back to the network device.

Therefore, the accuracy of the CSI is very important to the performance of the system.

Summary of the invention

Optionally, the uplink reference signal may be a sounding reference signal (SRS).

Optionally, according to the first indication information, the processing of the timing of the uplink reference signal is activated, and then, the timing of the uplink reference signal can be made unchanged for a period of time.

Based on the above technical solution, the network device can restrict or control the uplink reference signal timing adjustment behavior of the terminal device through the first indication information, so that the uplink reference signal timing remains unchanged for a period of time, thereby reducing the amount of input in the calculation of the feature space. Error, reduce the impact on the uplink channel estimation, ensure the performance of the channel state information (channel state information, CSI) acquisition scheme based on partial reciprocity, and improve the overall system performance.

With reference to the first aspect, in some implementations of the first aspect, receiving second indication information from the network device, where the second indication information is used to indicate the deactivation of the uplink reference signal timing processing; The second indication information deactivates the processing of uplink reference signal timing.

Optionally, deactivating the processing of the timing of the uplink reference signal can also be understood as stopping the processing of the timing of the uplink reference signal.

Based on the foregoing technical solution, the network device can deactivate the processing of the uplink reference signal timing by the terminal device through the second indication information, so as to ensure normal communication.

With reference to the first aspect, in some implementations of the first aspect, the processing of the uplink reference signal timing includes: the uplink reference signal timing remains unchanged within one or more time windows; or, in one or more time windows; Or report the adjustment of the uplink reference signal timing within multiple time windows.

Based on the above technical solution, the network device restricts or controls the adjustment behavior of the uplink reference signal timing of the terminal device, so that the terminal device keeps the uplink reference signal timing unchanged for a period of time. Alternatively, the network device restricts or controls the timing adjustment behavior of the terminal device's uplink reference signal, so that the terminal device reports the timing adjustment within a period of time, so that the network device can compensate for the timing adjustment, so that the uplink reference signal timing can also be kept unchanged.

With reference to the first aspect, in some implementations of the first aspect, if the uplink reference signal timing remains unchanged within a time window, or the uplink reference signal timing adjustment is reported within a time window, the The start time unit of the time window is: the time unit at which the first indication information is received, or the Nth time unit after the first indication information is received, or, after the first indication information is received After that, the time unit for transmitting the uplink reference signal for the Kth time; N and K are positive integers.

For example, N and K may be pre-set, such as pre-defined by the protocol; alternatively, they can also be configured by network equipment; alternatively, they can also be pre-appointed, which is not limited.

For example, after receiving the first indication information, the time unit for sending the uplink reference signal for the Kth time can be understood as the time unit for sending the uplink reference signal for the Kth time after the terminal device receives the first indication information. It can be understood that for the Kth time, the terminal device may start counting after receiving the first indication information.

For example, K is 1, that is, after the terminal device receives the first indication information, it starts at the time unit when the uplink reference signal is sent for the first time, and the uplink reference signal timing remains unchanged within a time window, or reports within a time window Uplink reference signal timing adjustment.

With reference to the first aspect, in some implementations of the first aspect, if the uplink reference signal timing remains unchanged within a time window, or the uplink reference signal timing adjustment is reported within a time window, the The end time unit of the time window is: the time unit for receiving the second indication information from the network device, the second indication information is used to indicate the deactivation of the uplink reference signal timing processing, or, the time The Lth time unit after the start time unit of the window, or, the time unit after J time units have passed after the start time unit of the time window, or, after receiving the first indication information, or , After activating the processing of the timing of the uplink reference signal, send the time unit of the M-th uplink reference signal; L, J, and M are positive integers.

Optionally, the end time unit of the time window is the Lth time unit after the start time unit of the time window, which means that after the terminal device starts to keep the uplink reference signal timing unchanged, it can be after the start time unit of the time window In the Lth time unit, the processing of the timing of the uplink reference signal is deactivated, that is, the timing of the uplink reference signal is no longer kept unchanged, or in other words, the timing of the uplink reference signal is variable. In other words, from the perspective of length, starting from the start time unit of the time window, the uplink reference signal timing remains unchanged for L time units.

Optionally, the end time unit of the time window is the time unit after J time units have passed after the start time unit of the time window, which means that after the terminal device starts to keep the uplink reference signal timing unchanged, it can be at the beginning of the time window.

In other words, from the perspective of length, starting from the start time unit of the time window, the uplink reference signal timing remains unchanged for (J+1) time units.

For example, after receiving the first indication information, the time unit for sending the uplink reference signal for the Mth time can be understood as the time unit for sending the uplink reference signal for the Mth time after the terminal device receives the first indication information, That is, the Mth time can start counting after receiving the first indication information.

Or, for example, after activating the processing of the uplink reference signal timing, the time unit for sending the M-th uplink reference signal, it can be understood that the terminal device may also activate the processing of the uplink reference signal timing for the M-th time, Start counting.

Optionally, the end time unit of the first time window is the time unit after R time units have passed after the start time unit of the first time window, in other words, from the start time unit of the first time window Initially, the timing of the uplink reference signal remains unchanged for (R+1) time units until the timing of the uplink reference signal is kept unchanged during the second time window.

For example, after receiving the first indication information, the time unit for sending the uplink reference signal for the Qth time can be understood as the time unit for sending the uplink reference signal for the Qth time after the terminal device receives the first indication information. That is, for the Qth time, the terminal device can start counting after receiving the first indication information.

Or, for example, after activating the processing of the uplink reference signal timing, the time unit for sending the Q-th uplink reference signal, it can be understood that the terminal device may also activate the processing of the uplink reference signal timing for the Q-th time, Start counting.

In order to facilitate the understanding of the embodiments of the present application, the following first briefly introduces several terms involved in the present application.

1. Precoding technology: When the channel status is known, the network equipment can process the signal to be sent with the help of a precoding matrix that matches the channel status, so that the precoded signal to be sent is adapted to the channel, thereby This reduces the complexity for the receiving device to eliminate the influence between channels. Therefore, through the precoding processing of the signal to be transmitted, the quality of the received signal (for example, the signal to interference plus noise ratio (SINR), etc.) can be improved. Therefore, the use of precoding technology can realize the transmission on the same time-frequency resource between the sending device and multiple receiving devices, that is, realizing multiple user multiple input multiple output (MU-MIMO). It should be understood that the relevant description of the precoding technology herein is only an example for ease of understanding, and is not used to limit the protection scope of the embodiments of the present application. In the specific implementation process, the sending device may also perform precoding in other ways. For example, when channel information (such as but not limited to a channel matrix) cannot be obtained, precoding is performed using a preset precoding matrix or a weighting processing method. For brevity, the specific content will not be repeated in this article.

2. Channel reciprocity: In the time division duplexing (TDD) mode, the uplink and downlink channels transmit signals on the same frequency domain resources and different time domain resources. In a relatively short time (for example, the coherence time of channel propagation), it can be considered that the channel fading experienced by the signals on the uplink and downlink channels is the same. This is the reciprocity of the uplink and downlink channels. Based on the reciprocity of the uplink and downlink channels, the network equipment can measure the uplink channel based on the uplink reference signal, such as sounding reference signal (SRS), and can estimate the downlink channel based on the uplink channel, so that it can be used for downlink transmission. The precoding matrix.

In frequency division duplexing (FDD) mode, the uplink and downlink channels have partial reciprocity, for example, the reciprocity of the angle and the reciprocity of the delay, in other words, the delay and the angle are in the FDD The uplink and downlink channels in the mode are reciprocal. Therefore, angle and delay can also be called reciprocity parameters.

Since the signal is transmitted through the wireless channel, it can reach the receiving antenna through multiple paths from the transmitting antenna. Multipath time delay causes frequency selective fading, which is the change of frequency domain channel. The time delay is the transmission time of the wireless signal on different transmission paths, which is determined by the distance and speed, and has nothing to do with the frequency domain of the wireless signal. When signals are transmitted on different transmission paths, there are different transmission delays due to different distances. Therefore, the uplink and downlink channels in the FDD mode with delay can be considered the same, or in other words, reciprocal.

In addition, the angle may refer to the angle of arrival (AOA) at which the signal reaches the receiving antenna via the wireless channel, or may refer to the angle of departure (AOD) at which the signal is transmitted through the transmitting antenna. In the embodiment of the present application, the angle may refer to the angle of arrival at which the uplink signal reaches the network device, or may refer to the departure angle of the network device to transmit the downlink signal. The arrival angle of the uplink reference signal and the departure angle of the downlink reference signal may be considered the same, or in other words, reciprocal. Therefore, the angle of the uplink and downlink channels in FDD mode has reciprocity.

3. Reference signal (reference signal, RS): It can also be called a pilot (pilot), reference sequence, etc. In the embodiment of the present application, the reference signal may be a reference signal used for channel measurement. For example, the reference signal may be a channel state information reference signal (CSI-RS) used for downlink channel measurement, or a sounding reference signal (sounding reference signal, SRS) used for uplink channel measurement. It should be understood that the reference signals listed above are only examples and should not constitute any limitation to this application. This application does not exclude the possibility of defining other reference signals in future agreements to achieve the same or similar functions.

In FDD mode, the angles and delays of the uplink and downlink channels are reciprocal. Therefore, the K angle vectors and L delay vectors obtained from the uplink channel measurement can be loaded into the downlink reference signal, so that the terminal equipment can be based on the received precoding Reference signal for downlink channel measurement. Wherein, K and L are both integers greater than or equal to 1. Of course, it is also possible to load the K angle vectors obtained by the uplink channel measurement to the downlink reference signal, and whether the delay vector is to be loaded to the downlink reference signal is not limited. Alternatively, the L delay vectors obtained by the uplink channel measurement may be loaded to the downlink reference signal, and whether the angle vector is to be loaded to the downlink reference signal is not limited.

Network equipment can take advantage of the partial reciprocity of FDD, combine terminal equipment to feedback non-reciprocal information, obtain channel state information (CSI), and perform signal precoding to improve system performance, reduce terminal equipment complexity, and Feedback overhead.

In order to obtain the uplink channel information, the network device can project the uplink channel on a certain spatial base (S) or frequency domain (F), as shown below: H _UL =SC _UL F ^H.

Among them, H _UL can represent the space-frequency matrix obtained by the uplink channel measurement. S may represent a matrix constructed by one or more (for example, K) angle vectors. F may represent a matrix constructed by one or more (for example, L) delay vectors. C may represent a coefficient matrix formed by weighting coefficients corresponding to each of the K angle vectors and each of the L delay vectors. The superscript H represents the conjugate transpose, for example, F ^H represents the conjugate transpose of the matrix (or vector) F.

The space-domain basis S and the frequency-domain basis F can be used to characterize the feature space of the uplink channel. In order to obtain the characteristic space of the uplink channel, the network device can estimate it according to the uplink reference signal received in advance, such as SRS.

In order to obtain the feature space of the uplink channel, the network device can estimate and calculate the feature space of multiple SRSs, as shown in FIG. 3.

In the measurement window, the terminal device sends multiple SRSs to the network device in one or more time windows. If the timing of the intermediate uplink reference signal is adjusted, errors will be introduced when calculating the feature space, which will affect the estimation of the uplink channel information, which will also degrade the overall system performance.

In view of this, this application provides a method to process or adjust the timing of the uplink reference signal so that the timing of the uplink reference signal remains unchanged for a period of time to ensure the performance of the CSI acquisition scheme based on FDD partial reciprocity.

The various embodiments provided in the present application will be described in detail below with reference to the accompanying drawings.

FIG. 4 is a schematic interaction diagram of a method 400 for receiving instructions provided by an embodiment of the present application. The method 400 may include the following steps.

410: The terminal device receives the first indication information from the network device.

The first indication information is used to indicate the activation of the processing of the uplink reference signal timing.

420. According to the first indication information, the terminal device activates processing on the timing of the uplink reference signal.

It can be understood that the terminal device activates the processing of the uplink reference signal timing according to the first indication information. For example, the first indication information may also be referred to as an activation command.

Optionally, the embodiment of the present application also provides at least two ways to deactivate the processing of the uplink reference signal timing.

Manner 1: The terminal device deactivates or stops processing the uplink reference signal timing according to the deactivation command.

In this manner, the method 400 may further include step 430 and step 440.

430. The terminal device receives second indication information from the network device, where the second indication information is used to instruct to deactivate the processing of the uplink reference signal timing.

440. According to the second indication information, the terminal device deactivates the processing of the uplink reference signal timing.

In other words, the terminal device may deactivate the processing of the uplink reference signal timing based on the second indication information sent by the network device. For example, the second indication information may also be referred to as a deactivation command.

Manner 2: The terminal device deactivates or stops processing the uplink reference signal timing according to the information about the activation time.

A possible design can be pre-defined or pre-configured with the activation duration of the network device. After starting to activate the processing of the uplink reference signal timing, within the activation duration, the terminal device activates the processing of the uplink reference signal timing; after the activation duration expires, the terminal device deactivates or stops processing the uplink reference signal timing.

Another possible design can be realized by a timer. After starting to activate the processing of the timing of the uplink reference signal, the timer can be started with a period of time as the time length. During the operation of the timer, the terminal device activates the processing of the timing of the uplink reference signal; after the timer expires, the terminal device deactivates or stops the processing of the timing of the uplink reference signal.

The duration of activation and the start time of activation are described in detail below.

It should be understood that the foregoing manner 1 and manner 2 are only exemplary descriptions, and the embodiments of the present application are not limited thereto. Any manner that can enable the terminal device to deactivate or stop processing the uplink reference signal timing after a period of time is not limited. It falls into the protection scope of the embodiments of this application.

Optionally, the processing of uplink reference signal timing may include at least the following two solutions:

Solution 1: The uplink reference signal timing remains unchanged in one or more time windows;

Solution 2: Adjust the timing of reporting the uplink reference signal within one or more time windows.

The above two schemes are described in detail below.

Solution 1: The uplink reference signal timing remains unchanged in one or more time windows.

That is, the network device may send the first indication information to the terminal device, where the first indication information is used to instruct the terminal device to keep the uplink reference signal timing unchanged within one or more time windows. After receiving the first indication information, the terminal device does not adjust the uplink reference signal timing within one or more time windows.

Wherein, the one or more time windows may be measurement windows. That is, in the measurement window, keep the uplink reference signal timing unchanged.

For example, the measurement window may be preset, such as a predetermined protocol; or, it may also be configured by a network device, which is not limited.

Regarding the start time and end time of the measurement window, there are two descriptions.

Case 1. Take a time window as an example.

It is assumed that the network device sends first indication information to the terminal device, and the first indication information is used to instruct the terminal device to keep the uplink reference signal timing unchanged within a time window.

The upper row reference signal is SRS, as shown in Figure 5. The network device sends the first instruction information to the terminal device. After receiving the first indication information, the terminal device keeps the uplink reference signal timing unchanged in a time window, that is, the SRS timing does not change.

Optionally, as shown in Figure 5. The network device may send the second indication information to the terminal device. After the terminal device receives the second indication information, the uplink reference signal timing is variable, that is, the SRS timing is variable.

It should be understood that in the embodiment of the present application, the uplink reference signal timing is variable, which means that the terminal device no longer keeps the uplink reference signal timing unchanged, and does not mean that the uplink reference signal timing must change. Whether the timing of the uplink reference signal changes may be affected by other factors, which is not limited in the embodiment of the present application.

The start time and end time of the measurement window in case 1 are described below respectively.

1. The start time of the measurement window.

Then, the starting time unit of the time window can be any one of the following: the time unit at which the terminal device receives the first indication information, the Nth time unit after the terminal device receives the first indication information, and the terminal device receives the first indication information. A time unit for sending the Kth uplink reference signal after the indication information. Among them, N and K are positive integers.

In a possible design, after receiving the first indication information, the terminal device may keep the uplink reference signal timing unchanged starting from the time unit when the first indication information is received.

In another possible design, after receiving the first indication information, the terminal device may start at the Nth time unit after receiving the first indication information, and keep the uplink reference signal timing unchanged.

In another possible design, after receiving the first indication information, the terminal device may start at the time unit when the uplink reference signal is sent for the Kth time, and keep the uplink reference signal timing unchanged. It can be understood that for the Kth time, the terminal device may start counting after receiving the first indication information. In other words, after receiving the first indication information, the terminal device does not immediately start to keep the uplink reference signal timing unchanged, but at the Kth time, such as the first time, to start sending the uplink reference signal and keep the uplink reference timing unchanged.

2. The end time of the measurement window.

Then, the end time unit of the time window can be any one of the following: the time unit at which the terminal device receives the second indication information, the Yth time unit after the terminal device receives the second indication information, and the terminal device receives the second indication information. Z time units after the instruction information, the Lth time unit after the start time unit of the time window, the time unit after J time units after the start time unit of the time window, after receiving the first instruction information Or the time unit for sending the M-th uplink reference signal after activating the processing of the uplink reference signal timing. Among them, L, J and M are positive integers.

A possible design is that after the terminal device starts to keep the uplink reference signal timing unchanged, it can deactivate or stop processing the uplink reference signal timing at the time unit when the second indication information is received, that is, no longer maintain the uplink reference signal timing No change, or in other words, the uplink reference signal timing is variable.

In another possible design, after the terminal device starts to keep the uplink reference signal timing unchanged, it can deactivate or stop processing the uplink reference signal timing at Y time units after receiving the second indication information, that is, no longer keep it. The timing of the uplink reference signal is unchanged, or in other words, the timing of the uplink reference signal is variable.

In another possible design, after the terminal device starts to keep the uplink reference signal timing unchanged, it can deactivate or stop processing the uplink reference signal timing after Z time units after receiving the second indication information, that is, no longer Keep the uplink reference signal timing unchanged, or in other words, the uplink reference signal timing is variable.

In another possible design, after the terminal device starts to keep the uplink reference signal timing unchanged, it can deactivate or stop processing the uplink reference signal timing at the Lth time unit after the start time unit of the time window, that is, not Then keep the uplink reference signal timing unchanged, or in other words, the uplink reference signal timing is variable.

In other words, from the perspective of length, starting from the start time unit of the time window, the uplink reference signal timing remains unchanged for L time units.

For example, the L time units can also be understood as the activation time length or the time length of the timer as described in the above manner 2.

Another possible design. After the terminal device starts to keep the uplink reference signal timing unchanged, it can deactivate or stop processing the uplink reference signal timing at the time unit after J time units have passed after the start time unit of the time window. , That is, the uplink reference signal timing is no longer kept unchanged, or in other words, the uplink reference signal timing is variable.

In other words, from the perspective of length, starting from the start time unit of the time window, the uplink reference signal timing remains unchanged for (J+1) time units.

For example, the (J+1) time units can also be understood as the activation time length or the time length of the timer as described in the above manner 2.

In another possible design, after the terminal device starts to keep the uplink reference signal timing unchanged, after receiving the first indication information, it may send the time unit of the Mth uplink reference signal to deactivate or stop timing the uplink reference signal. Processing, that is, the timing of the uplink reference signal is no longer kept unchanged, or in other words, the timing of the uplink reference signal is variable. In other words, the time unit for sending the M-th uplink reference signal may be counted from the M-th time after receiving the first indication information.

In another possible design, after the terminal device starts to keep the uplink reference signal timing unchanged, it can send the time unit of the Mth uplink reference signal after activating the processing of the uplink reference signal timing to deactivate or stop the uplink reference signal timing. The timing processing means that the timing of the uplink reference signal is no longer kept unchanged, or in other words, the timing of the uplink reference signal is variable. That is to say, for the Mth time, the terminal device can start counting after the terminal device activates the processing of the uplink reference signal timing.

It should be understood that the above-mentioned possible designs are only exemplary descriptions, and any modification that belongs to the above-mentioned several possible designs falls into the protection scope of the embodiments of the present application.

Case 2. Take multiple time windows as an example.

It is assumed that the network device sends first indication information to the terminal device, and the first indication information is used to instruct the terminal device to keep the uplink reference signal timing unchanged in multiple time windows.

The upper row reference signal is SRS, as shown in Figure 6. The network device sends the first instruction information to the terminal device. After receiving the first indication information, the terminal device keeps the uplink reference signal timing unchanged in multiple time windows, that is, the SRS timing does not change. In the time outside the multiple time windows, the uplink reference signal timing is variable, that is, the SRS timing is variable.

Optionally, as shown in Figure 6. The network device may send the second indication information to the terminal device. After the terminal device receives the second indication information, the uplink reference signal timing is variable, that is, the SRS timing is variable.

The following describes the start time and end time of the measurement window in case 2 respectively.

1. The start time of the measurement window.

Assume that the network device sends first indication information to the terminal device, where the first indication information is used to instruct the terminal device to keep the uplink reference signal timing unchanged in multiple time windows.

Then, the start time unit of the first time window among the multiple time windows can be any one of the following: the time unit at which the terminal device receives the first indication information, and the S th unit after the terminal device receives the first indication information The time unit, the time unit for sending the P-th uplink reference signal after the terminal device receives the first indication information. Among them, S and P are positive integers.

For example, S and P may be preset, such as prescribed in advance by the protocol; or, they may also be configured by the network device; or, they may also be pre-appointed, which is not limited.

In another possible design, after receiving the first indication information, the terminal device may start at the Sth time unit after receiving the first indication information, and keep the uplink reference signal timing unchanged.

In another possible design, after receiving the first indication information, the terminal device may start at the time unit of sending the P-th uplink reference signal, and keep the uplink reference signal timing unchanged. It can be understood that for the Pth time, the terminal device may start counting after receiving the first indication information. In other words, after receiving the first indication information, the terminal device does not immediately start to keep the uplink reference signal timing unchanged, but at the Pth time, such as the first time, to start sending the uplink reference signal and keep the uplink reference timing unchanged.

For example, A1 and A2 may be pre-set, such as pre-defined by the protocol; alternatively, they can also be configured by the network device; alternatively, they can also be pre-appointed, which is not limited.

2. The end time of the measurement window.

Then, the end time unit of the first time window in the multiple time windows can be any of the following: the T-th time unit after the start time unit of the first time window, the start of the first time window After the time unit, the time unit after R time units has passed, the time unit for sending the Q-th uplink reference signal after receiving the first indication information or after activating the processing of the uplink reference signal timing. Among them, T, R and Q are positive integers.

For example, T, R, and Q may be preset, such as pre-defined in the protocol; or, they may also be configured by a network device; or, they may also be pre-appointed, which is not limited.

A possible design is that after the terminal device starts to keep the uplink reference signal timing unchanged, it can deactivate or stop processing the uplink reference signal timing at the T-th time unit after the start time unit of the first time window. That is, the timing of the uplink reference signal is no longer kept unchanged, or in other words, the timing of the uplink reference signal is variable until the second time window starts.

In other words, starting from the start time unit of the first time window, the uplink reference signal timing remains unchanged for T time units until the uplink reference signal timing is kept unchanged during the second time window.

For example, the T time units can also be understood as the activation time length or the time length of the timer as described in the above manner 2.

It should be understood that there is no limitation as to whether there is an interval between adjacent time windows or how long the interval is. Take the first time window and the second time window as examples. It can be the end of the first time window and the start of the second time window, or, it can be the end of the first time window, after a period of time (for example, it can be a predetermined or configured time length), and the second time The window begins.

In another possible design, after the terminal device starts to keep the uplink reference signal timing unchanged, it can deactivate or stop the uplink reference signal at the time unit after R time units have passed after the start time unit of the first time window. Timing processing, that is, no longer keeping the uplink reference signal timing unchanged, or in other words, the uplink reference signal timing is variable until the second time window starts.

In other words, starting from the start time unit of the first time window, the uplink reference signal timing remains unchanged for (R+1) time units until the uplink reference signal timing is kept unchanged during the second time window.

For example, the (R+1) time units can also be understood as the activation time length or the time length of the timer as described in the above manner 2.

In another possible design, after the terminal device starts to keep the uplink reference signal timing unchanged, after receiving the first indication information, the time unit of the Qth uplink reference signal can be sent to deactivate or stop timing the uplink reference signal. Processing, that is, the uplink reference signal timing is no longer kept unchanged, or in other words, the uplink reference signal timing is variable until the second time window starts. In other words, for the Qth time, the terminal device can start counting after receiving the first indication information.

In another possible design, after the terminal device starts to keep the uplink reference signal timing unchanged, it can send the Qth uplink reference signal time unit after activating the uplink reference signal timing processing to deactivate or stop the uplink reference signal timing. The timing processing means that the timing of the uplink reference signal is no longer kept unchanged, or in other words, the timing of the uplink reference signal is variable. That is to say, for the Qth time, the terminal device can also start counting after the terminal device activates the processing of the uplink reference signal timing.

For example, B1 and B2 may be pre-set, such as pre-defined by the protocol; alternatively, they can also be configured by network equipment; alternatively, they can also be pre-appointed, which is not limited.

In case 2, multiple time windows are involved. For example, the time length of each time window may be equal.

Based on scheme 1, the network equipment restricts or controls the uplink reference signal timing adjustment behavior of the terminal equipment, so that the terminal equipment keeps the uplink reference signal timing unchanged for a period of time, thereby avoiding the impact on the feature space calculation, and ensuring that it is based on FDD Part of the performance of the reciprocal CSI acquisition scheme.

Scenario 2 is introduced below.

That is, the network device may send the first indication information to the terminal device, where the first indication information is used to instruct the terminal device to report the adjustment of the uplink reference signal timing within one or more time windows.

The network device may compensate for the adjustment of the timing of the uplink reference signal according to the adjustment of the timing of the uplink reference signal reported by the terminal device, so that the timing of the uplink reference signal remains unchanged within one or more time windows.

Regarding the start time and end time of the measurement window, scheme 2 is similar to scheme 1. For details, please refer to the description in scheme 1.

Based on scheme 2, the network equipment restricts or controls the terminal equipment's uplink reference signal timing adjustment behavior, so that the terminal device can report the timing adjustment within a period of time, so that the network device can compensate for the timing adjustment, so that the uplink reference signal timing can also be maintained In this way, the influence on feature space calculation can be avoided, and the performance of the CSI acquisition scheme based on FDD partial reciprocity can also be guaranteed.

The foregoing exemplarily introduces two solutions for processing the timing of the uplink reference signal. Any solution that can keep the timing of the uplink reference signal unchanged within a certain period of time falls within the protection scope of the embodiments of the present application.

Optionally, the first indication information or the second indication information may be indicated in an explicit manner.

For example, the first indication information or the second indication information may be carried in one or a combination of at least two of radio resource control signaling, media access control (MAC) layer signaling, and physical layer signaling . Among them, radio resource control signaling includes, for example, radio resource control (RRC) signaling; MAC layer signaling includes, for example, MAC control element (CE); physical layer signaling includes, for example, downlink control information (downlink control). information, DCI).

Optionally, the first indication information or the second indication information may be indicated implicitly.

For example, take the first indication information as an example.

In an example, the first indication information may be implemented based on the activation signaling of the FDD partial reciprocity CSI acquisition scheme.

That is, after receiving the activation signaling of the CSI acquisition scheme based on the FDD partial reciprocity, the terminal device activates the processing of the timing of the uplink reference signal. For example, after the terminal device receives the activation signaling of the CSI acquisition scheme based on the FDD partial reciprocity, the uplink reference signal timing remains unchanged within one or more time windows. For another example, after receiving the activation signaling of the CSI acquisition scheme based on FDD partial reciprocity, the terminal device reports the adjustment of the uplink reference signal timing within one or more time windows.

In another example, the first indication information may be implemented based on activation signaling of the feature space scheme.

In other words, after receiving the activation signaling based on the feature space scheme, the terminal device activates the processing of the timing of the uplink reference signal. For example, after the terminal device receives the activation signaling based on the feature space scheme, the uplink reference signal timing remains unchanged within one or more time windows. For another example, after receiving the activation signaling based on the feature space scheme, the terminal device reports the adjustment of the uplink reference signal timing within one or more time windows.

For another example, take the second indication information as an example.

In an example, the second indication information may be implemented based on the deactivation signaling of the FDD partial reciprocity CSI acquisition scheme.

That is, after receiving the deactivation signaling of the CSI acquisition scheme based on the FDD partial reciprocity, the terminal device deactivates or stops processing the uplink reference signal timing. For example, after receiving the deactivation signaling of the CSI acquisition scheme based on FDD partial reciprocity, the terminal device no longer keeps the uplink reference signal timing unchanged. For another example, after the terminal device receives the deactivation signaling of the CSI acquisition scheme based on the FDD partial reciprocity, it may no longer report the adjustment of the uplink reference signal timing.

In another example, the second indication information may be implemented based on deactivation signaling of the feature space scheme.

In other words, after receiving the deactivation signaling based on the feature space scheme, the terminal device deactivates or stops processing the timing of the uplink reference signal. For example, after receiving the deactivation signaling based on the feature space scheme, the terminal device no longer keeps the uplink reference signal timing unchanged. For another example, after receiving the deactivation signaling based on the feature space scheme, the terminal device may no longer report the adjustment of the uplink reference signal timing.

It should be understood that, in the embodiment shown in the method 400, the uplink reference signal may be replaced with an SRS.

In this application, the network equipment restricts or controls the adjustment behavior of the uplink reference signal timing of the terminal device, so that the terminal device keeps the uplink reference signal timing unchanged for a period of time, thereby avoiding the influence on the feature space calculation, and also ensuring that it is based on FDD Part of the performance of the reciprocal CSI acquisition scheme.

In addition, in this application, the network device restricts or controls the terminal device's uplink reference signal timing adjustment behavior, so that the terminal device reports the timing adjustment within a period of time, so that the network device can compensate for the timing adjustment, so that the uplink reference can also be maintained. The signal timing is unchanged, thereby avoiding the influence on the feature space calculation, and also ensuring the performance of the CSI acquisition scheme based on FDD partial reciprocity.
