Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a signal receiving method, device, electronic device and computer-readable storage medium. Background Art

[0002] In the existing communication technology, each base station flexibly determines its own frame structure configuration according to its own uplink and downlink service characteristics, resulting in that in some symbols, adjacent base stations may have opposite uplink and downlink propagation directions, thereby causing cross-link interference (CLI) between terminals. In order to suppress the above-mentioned inter-terminal CLI (UE-UE CLI for short), the relevant technology proposes an interference detection reference signal (Cross-link interference-Reference Signal, CLI-RS) for measuring UE-UE CLI to detect UE-UE CLI interference strength. However, the downlink reception timing of the serving cell where the terminal is located is not aligned with the reception timing of CLI-RS, which makes it impossible to accurately detect the signal strength of CLI-RS.

[0159] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0160] In existing communication technologies, each base station flexibly determines its own frame structure configuration according to its own uplink and downlink service characteristics, resulting in Figure 1 In time slot #2 in the time slot, the adjacent base stations may have opposite uplink and downlink transmission directions. At the same time, when the adjacent base stations have opposite transmission directions, it will cause CLI interference between base stations (such as Figure 1 The downlink signal transmission of the first network device may interfere with the uplink signal reception of the second network device), and CLI interference between terminals (such as Figure 1 The uplink signal transmission of the second terminal in the adjacent first terminal may interfere with the downlink signal reception of the adjacent first terminal. In order to suppress UE-UE CLI, it is first necessary to detect the UE-UE CLI interference strength. To this end, the related art proposes a first signal for measuring UE-UE CLI to detect the UE-UE CLI interference strength.

[0161] It should be noted that the first terminal mentioned in the present application can be understood as the interfered terminal, and the second terminal can be understood as the interfering terminal. The first network device is the base station of the service cell where the first terminal is located, and it can also be referred to as the first network device serving the first terminal; the second network device is the base station of the service cell where the second terminal is located, and it can also be referred to as the second network device serving the second terminal; the first signal can be used to detect CLI interference between the first terminal and the second terminal.

[0162] like Figure 2 As shown, the second network device configures the second terminal to send a first signal. The first network device obtains the first signal configuration, and configures it to the first terminal through a standardized first signal. The first terminal detects the signal strength of the first signal according to the received first signal configuration, and reports the detected signal strength of the first signal to the first network device. Based on the signal strength of the above-mentioned first signal, the first network device determines whether the uplink signal transmission of the second terminal will cause strong interference to the downlink signal reception of the first terminal, and takes subsequent interference suppression measures accordingly. Exemplarily, the aforementioned interference suppression measures can be coordinated between the first network device and the second network device to schedule the time domain, frequency domain, and / or spatial domain resources of the second terminal and the first terminal for uplink and downlink transmission.

[0163] It should be noted that the relevant technology has not yet clarified the signaling interface for exchanging first signal configuration information, coordination scheduling information and other related information between the first network device and the second network device.

[0164] The first terminal usually performs downlink signal detection and reference signal measurement based on the downlink reception timing of the serving cell. However, there is a significant difference between the downlink reception timing of the first terminal and the arrival time of the first signal sent by the second terminal. The prior art does not solve the problem of which timing relationship (timing) the first terminal uses to detect the first signal sent by the second terminal. The aforementioned first signal can be an interference detection reference signal (Cross-link interference-Reference Signal, CLI-RS).

[0165] See also Figure 3 , Figure 3 1 is a flowchart of a signal receiving method applied to a first terminal provided in an embodiment of the present application, and is applied to a first terminal. Figure 3 As shown, the following steps are included:

[0166] Step 301: Determine timing adjustment parameters;

[0167] In this step, as mentioned above, since there is a significant difference between the downlink reception timing of the first terminal and the arrival time of the first signal sent by the second terminal, the first terminal needs to determine the reception timing adjustment duration of the first signal in order to effectively detect the signal strength of the first signal. Figure 2 As shown, let the spatial propagation delay from the first terminal to the first network device be τ v,1 , the spatial propagation delay from the second terminal to the second network device is τ a,2 , the spatial propagation delay from the first terminal to the second terminal is τ v,a .

[0168] The problem of misalignment between the downlink reception timing of the serving cell where the first terminal is located and the arrival time of the first signal sent by the second terminal is explained in detail below.

[0169] It is assumed that the clock synchronization and timing of the first network device and the second network device are aligned, that is, the downlink signal sending timing of the two (that is, the starting time of the downlink (DL) symbol on the base station side) is aligned, and the uplink signal receiving timing of the two (that is, the starting time of the uplink (UL) symbol on the base station side) is aligned, such as Figure 4 As shown, t 1 is the downlink signal sending timing of the second network device (also consistent with the downlink signal sending timing of the first network device); t2 and t 2 ' are respectively the uplink signal reception timing of the second network device and the first network device; t 3 and t 3 ' are respectively the uplink signal sending timings of the second terminal and the first terminal, that is, the starting time when the second terminal sends the first signal; t 4 is the downlink signal reception timing of the first terminal (ie, the start time of receiving the DL symbol); t 5 The starting time when the first signal sent by the second terminal arrives at the first terminal;

[0170] like Figure 4 As shown, the starting time t at which the first signal sent by the second terminal arrives at the first terminal 5 Than the downlink signal reception timing t of the first terminal 4 A period of time has been advanced, and the advance amount is recorded as T 1 , T 1 It can be determined by the following formula 1:

[0171] T 1 =t 4 -t 5 =N TA offset T c +τ v,1 +τ a,2 -τ v,a (1)

[0172] Among them, N TA offset T c τ is the timing offset, which indicates the timing advance offset of the uplink signal reception timing at the base station side relative to the downlink signal transmission timing at the base station side; v,1 is the spatial propagation delay from the first terminal to the first network device, τ a,2 is the spatial propagation delay from the second terminal to the second network device, τ v,a is the spatial propagation delay from the first terminal to the second terminal.

[0173] In the prior art, the first terminal usually performs reference signal measurement based on the downlink reception timing of the serving cell. As mentioned above, the starting time t of the first signal arriving at the first terminal is 5 Than the downlink signal reception timing t of the first terminal 4 T in advance 1 Duration, and T 1 The duration cannot be ignored, so due to the above timing deviation T 1 Due to the existence of the first signal transmitted by the second terminal, according to the prior art, the first terminal cannot completely detect the first signal transmitted by the second terminal, thereby causing the first terminal to measure the signal strength of the first signal inaccurately.

[0174] like Figure 4 As shown, we can also find that the starting time t of the first signal sent by the second terminal arriving at the first terminal is 5 Than the uplink signal sending timing t of the first terminal 3 'Advance a period of time, record the advance amount as T 2 , T 2 It can be determined by the following formula 2:

[0175] T 2 =t 3 ′-t 5 =τ v,1 +τ a,2 -τ v,a -N TA T c (2)

[0176] Where N TA T c is the timing adjustment amount, indicating the timing advance adjustment amount made by the first terminal according to the instruction of the first network device, where N TA T c ≈2τ v,1 .

[0177] In order to solve the problem of inaccurate signal strength detection in existing signal receiving methods, it is necessary to determine the reception timing adjustment duration of the first signal by the first terminal through the timing adjustment parameters determined by the various parameters in Formula 1 and / or Formula 2, thereby adjusting the reception timing of the first signal.

[0178] Step 302: Determine the reception timing adjustment duration of the first signal according to the timing adjustment parameter;

[0179] The first signal mentioned in this step may be a CLI-RS. CLI-RS includes but is not limited to uplink signals such as an uplink sounding reference signal (SRS), a physical random access channel (PRACH), a scheduling request (SR), and a wake-up signal (WUS). In some instances or applications, the SRS signal used for CLI detection is also referred to as CLI-SRS.

[0180] As mentioned above, the reception timing adjustment duration of the first signal can be represented by the first duration that the reception of the first signal is ahead of the reception timing of the first detection path of the corresponding downlink frame of the service cell where the first terminal is located, or by the second duration that the reception of the first signal is ahead of the transmission timing of the uplink frame, uplink signal or uplink channel. Different reception timing adjustment durations are determined by different timing adjustment parameters.

[0181] Note that the reception timing adjustment duration described in this case is a concept defined by this case, which is used to summarize the first duration and the second duration. In some embodiments, the reception timing adjustment duration may also be referred to as any one of: timing adjustment duration, timing adjustment amount, adjustment amount, and timing parameter. This case is not limited. In other embodiments, the technical specifications only describe the first duration or the second duration, and do not propose the concept of "reception timing adjustment duration". This situation should also fall within the scope of protection of this case.

[0182] Additionally, in some embodiments, the technical specification describes:

[0183] The reception of the first signal is ahead of the reception of the first detection path of the corresponding downlink frame of the reference cell by a variable A;

[0184] And / or, the reception of the first signal is ahead of the sending of the uplink frame, the uplink signal or the uplink channel by a variable B.

[0185] And the determination method of variable A and / or variable B is consistent with the description of claim 3 and subsequent claims of this case. This case also falls within the protection scope of this case.

[0186] Step 303: Determine a receiving timing of the first signal according to the receiving timing adjustment duration, wherein the first signal is used to measure interference between the first terminal and the second terminal.

[0187] In this step, the reception timing of the first signal is determined according to the reception timing adjustment duration determined by the timing adjustment parameters. As described above, the reception timing of the first signal is earlier than the reception of the first detection path of the corresponding downlink frame of the service cell where the first terminal is located by a first duration, or earlier than the transmission of the uplink frame, uplink signal or uplink channel by a second duration.

[0188] In one implementation, in order to effectively detect the signal strength of the first signal, the first terminal accurately estimates the value of the timing adjustment parameter used to monitor the first signal. Specifically, the timing adjustment parameter can be estimated by the first terminal itself, or can be directly determined by the indication information of the first network device. According to the reception timing adjustment duration determined by the timing adjustment parameter, the reception timing of the first signal is adjusted, so that the signal strength of the first signal can be accurately measured.

[0189] Optionally, the reception timing adjustment duration includes a first duration and / or a second duration;

[0190] The first signal is received before the first detection path of the corresponding downlink frame of the serving cell where the first terminal is located is received by the first time length;

[0191] And / or, the reception of the first signal is earlier than the sending of the uplink frame, the uplink signal or the uplink channel by the second time length.

[0192] In one implementation, the receiving timing adjustment duration includes a first duration and / or a second duration, and the first duration can be specifically understood as the aforementioned T 1 The second duration can be specifically understood as the aforementioned T 2 .

[0193] It should be noted that when the first duration or the second duration is a positive value, it indicates a timing advance, that is, the reception of the first signal is earlier than the reception of the first detection path of the corresponding downlink frame of the reference cell by the first duration, or the reception of the first signal is earlier than the sending of the uplink frame, the uplink signal or the uplink channel by the second duration; when the first duration or the second duration is a negative value, it indicates a timing delay, that is, the reception of the first signal is delayed by the negative of the first duration or its absolute value than the reception of the first detection path of the corresponding downlink frame of the reference cell, or the reception of the first signal is delayed by the negative of the second duration or its absolute value than the sending of the uplink frame, the uplink signal or the uplink channel.

[0194] It should be noted that this case includes three situations. In the first situation, only the first duration and its determination method are regulated (terminal self-estimation or based on network indication); in the second situation, only the second duration and its determination method are regulated (terminal self-estimation or based on network indication); in the third situation, both the first duration and the second duration are regulated, and on the basis of the determination methods of the first duration or the second duration given in the first and second situations (terminal self-estimation or based on network indication), the conversion relationship between the two durations is regulated.

[0195] In this implementation, the reception timing adjustment duration of the first signal includes the first duration and / or the second duration, which is conducive to specifically determining the first duration and the second duration according to the actual content of the specification.

[0196] Optionally, the second duration is determined according to a timing adjustment amount, a timing adjustment offset and the first duration, and the timing adjustment amount is determined according to a timing advance command.

[0197] In one implementation, the first duration and the second duration are standardized at the same time, and the method for determining the first duration (the terminal estimates it by itself or based on network instructions) is standardized, and the conversion relationship between the two durations is standardized. In this case, the second duration can be obtained based on the first duration. The second duration can be determined by the following formula 2:

[0198] T 2 =T 1 –(N TA +N TA offset )T c (2)

[0199] Among them, T 2 is the second duration, T 1 is the first duration, N TA is the timing adjustment amount, N TA offset The timing adjustment offset, T c The unit of delay.

[0200] In this implementation, the second duration is obtained based on the first duration, which is beneficial for subsequently calculating the second duration based on the relationship between the first duration and the second duration after the first duration is determined.

[0201] Optionally, the timing adjustment parameter includes a first timing adjustment parameter;

[0202] The determining of the timing adjustment parameter comprises:

[0203] Determining a timing adjustment amount, a timing adjustment offset, and a preset parameter, wherein the timing adjustment amount is determined according to the timing advance command;

[0204] Determining the first timing adjustment parameter according to the timing adjustment amount, the timing adjustment offset and the preset parameter;

[0205] The step of determining the reception timing adjustment duration of the first signal according to the timing adjustment parameter includes:

[0206] A first duration of the first signal is determined according to the first timing adjustment parameter.

[0207] As mentioned above, T 1 =t 4 -t 5 =N TA offset T c +τ v,1 +τ a,2 -τ v,a , since the first terminal can know N TA offset T c and τ v,1 But it is impossible to know the value of τ accurately. a,2 and τ v,a The value of .

[0208] Therefore, in one implementation mode, the first terminal can roughly estimate the first timing adjustment parameter A by itself. 1 =N TA offset T c +2τ v,1 -σ,N TA offset To adjust the offset, T c is the delay unit, τ v,1 is the propagation delay from the first terminal to the first network device, τ v,1 It can be determined according to the timing advance command of the first terminal, σ is a preset parameter, σ≥0, and the preset parameter σ represents the timing estimation error margin. v,1 =N TA T c , so A 1 =(N TA +N TA offset )T c -σ, where N TA Then, according to the first timing adjustment parameter, the first duration of the first signal can be determined as: T 1 =A 1 =(N TA +N TA offset )T c -σ,T 1 For the first duration.

[0209] In one embodiment, the preset parameter σ = 0. In this case, the “determining the first timing adjustment parameter according to the timing adjustment amount, the timing adjustment offset and the preset parameter” is equivalent to “determining the first timing adjustment parameter according to the timing adjustment amount and the timing adjustment offset”.

[0210] In this case, the preset parameter σ≥0. For the embodiment of the preset parameter σ=0, the “determine parameter A, parameter B, .., parameter X, and preset parameter” is equivalent to “determine parameter A, parameter B, ..., and parameter X”, and the “determine based on parameter A, parameter B, ..., parameter X, and preset parameter…” is equivalent to “determine based on parameter A, parameter B, ..., and parameter X…”. That is, this case simultaneously protects the schemes of “determine parameter A, parameter B, ..., and parameter X” and “determine based on parameter A, parameter B, ..., and parameter X…”. The same understanding is adopted in this article and will not be repeated in the following text.

[0211] In this implementation manner, the timing adjustment parameter is roughly estimated by the first terminal and does not require additional signaling indication, thereby reducing signaling overhead.

[0212] Optionally, the timing adjustment parameter includes a preset parameter;

[0213] The step of determining the reception timing adjustment duration of the first signal according to the timing adjustment parameter includes:

[0214] A second duration of the first signal is determined according to the preset parameters.

[0215] As mentioned above, T 2 =t 3 ′-t 5 =τ v,1 +τ a,2 -τ v,a -N TA T c , since the first terminal can know N TA offset T c and τ v,1 But it is impossible to know the value of τ accurately. a,2 and τ v,a The value of .

[0216] In one implementation manner, the timing adjustment parameter used by the first terminal to roughly estimate the second duration includes a preset parameter, so the second duration may be determined by the following calculation formula:

[0217] T 2 = -σ, where T 2 is the second duration, σ is a preset parameter, σ≥0, and the preset parameter represents a timing estimation error margin.

[0218] In this implementation, the determination of the timing adjustment parameter does not require additional signaling indication, thereby reducing signaling overhead.

[0219] Optionally, the timing adjustment parameter includes a second timing adjustment parameter or a third timing adjustment parameter;

[0220] The determining of the timing adjustment parameter comprises:

[0221] Receiving first indication information sent by a first network device, wherein the first indication information includes the second timing adjustment parameter or the third timing adjustment parameter;

[0222] The step of determining the reception timing adjustment duration of the first signal according to the timing adjustment parameter includes:

[0223] determining a first duration of the first signal according to the second timing adjustment parameter;

[0224] Or, determine a second duration of the first signal according to the third timing adjustment parameter.

[0225] In one implementation, the first network device is responsible for accurately estimating the timing adjustment parameter, including determining a second timing adjustment parameter for indicating the terminal to determine the first duration, and / or determining a third timing adjustment parameter for indicating the terminal to determine the second duration, and then sending the second timing adjustment parameter and / or the third timing adjustment parameter to the first terminal through first indication information. The first indication information also includes configuration information related to the first signal.

[0226] Specifically, the first duration can be determined by the following calculation formula:

[0227] Among them, T 1 is the first duration, A 2 is the second timing adjustment parameter, N TA offset To adjust the offset, T' c and T c are all delay units, τ v,1 is the propagation delay from the first terminal to the first network device, τ a,2 is the propagation delay from the second terminal to the second network device, τ v,a is the propagation delay from the first terminal to the second terminal, σ is a preset parameter, σ≥0, and the preset parameter represents the timing estimation error margin. c Can be equal to T c , or other values, which are not limited in this implementation.

[0228] The second duration is determined by the following calculation formula:

[0229] T 2 =A 3 ×T′ c ≈τ v,1 +τ a,2 -τ v,a –N TA T c -σ, where T 2 is the second duration, A 3 is the third timing adjustment parameter, T′ c is the delay unit, τ v,1 is the propagation delay from the first terminal to the first network device, τ a,2 is the propagation delay from the second terminal to the second network device, τ v,a is the propagation delay from the first terminal to the second terminal, N TA is the timing adjustment amount, σ is a preset parameter, σ≥0, and the preset parameter represents the timing estimation error margin.

[0230] In this implementation, the timing adjustment parameter is directly indicated by the first network device, which is conducive to improving the accuracy of timing adjustment parameter estimation, thereby more accurately determining the reception timing of the first signal.

[0235] The determining, according to the timing adjustment parameter, a reception timing adjustment duration of the first signal includes:

[0236] A first duration of the first signal is determined according to the fourth timing adjustment parameter, the timing adjustment amount, and the timing adjustment offset.

[0237] In one implementation, the first network device indicates part of the timing adjustment parameters through the second indication information, and then determines the first duration through the timing adjustment amount and the timing advance amount, specifically, including but not limited to the following two situations:

[0238] In the first case, the first network device indicates the fourth timing adjustment parameter A through the second indication information. 4 ×T′ c ≈τ a,2 -τ v,a -σ, where A 4 is the fourth timing adjustment parameter, T′ c is the delay unit, τ a,2 is the propagation delay from the second terminal to the second network device, τ v,a is the propagation delay from the first terminal to the second terminal, σ is a preset parameter, σ≥0, and the preset parameter represents the timing estimation error margin.

[0239] Then, the first duration is determined by using the fourth timing adjustment parameter, the timing adjustment amount, and the timing advance amount. The first duration can be determined by the following calculation formula:

[0250] A second duration of the first signal is determined according to the fourth timing adjustment parameter and the timing adjustment amount.

[0251] In one implementation, the first network device indicates part of the timing adjustment parameters through the second indication information, and then determines the second duration through the timing adjustment amount and the timing advance amount, specifically, including but not limited to the following two situations:

[0252] In the first case, the first network device indicates the fourth timing adjustment parameter A through the second indication information. 4 ×T′ c ≈τ a,2 -τ v,a -σ, where A 4 is the fourth timing adjustment parameter, τ a,2 is the propagation delay from the second terminal to the second network device, τ v,a is the propagation delay from the first terminal to the second terminal, T′ c represents the delay unit, σ is a preset parameter, σ≥0, and the preset parameter represents the timing estimation error margin.

[0259] See also Figure 5 , Figure 5 1 is a flow chart of a signal receiving method applied to a first network device provided in an embodiment of the present application, and is applied to the first network device. Figure 5 As shown, the following steps are included:

[0260] Step 501: Determine timing adjustment parameters;

[0261] In this step, the timing adjustment parameter is a parameter for adjusting the reception timing of the first terminal for the first signal. The timing adjustment parameter can be estimated by the first terminal itself or directly indicated by the first network device. The first network device can indicate all the timing adjustment parameters or some of the timing adjustment parameters.

[0262] Step 502: Send indication information including the timing adjustment parameter to the first terminal, wherein the indication information is used by the first terminal to determine a receiving timing adjustment duration of a first signal according to the timing adjustment parameter, and the first signal is used to measure interference between the first terminal and a second terminal.

[0263] In this step, the timing adjustment parameter determined by the first network device is sent to the first terminal along with the indication message sent by the first network device to the first terminal, and the first indication message may also include configuration information related to the first signal. The first signal is a signal for measuring interference between the first terminal and the second terminal.

[0264] In one implementation mode, in order to effectively detect the signal strength of the first signal, the first terminal needs to determine the reception timing adjustment duration of the first signal. The timing adjustment parameter is a parameter related to determining the reception timing adjustment duration of the first signal. The timing adjustment parameter can be estimated by the first terminal itself, or the first network device can be responsible for accurately estimating the timing adjustment parameter. In the case where the first network device is responsible for accurately estimating the timing adjustment parameter, the accuracy of the timing adjustment parameter can be improved, thereby more accurately determining the reception timing of the first signal.

[0265] Optionally, the indication information includes first indication information, and the timing adjustment parameter includes a second timing adjustment parameter or a third timing adjustment parameter.

[0266] In one implementation, the network device is responsible for accurately estimating all timing adjustment parameters. The timing adjustment parameters include a second timing adjustment parameter or a third timing adjustment parameter. The second timing adjustment parameter is used to indicate that the terminal determines a first duration of the first signal, the first duration being the duration of the reception of the first signal ahead of the reception of the first detection path of the corresponding downlink frame of the service cell where the first terminal is located, and the third timing adjustment parameter is used to indicate that the terminal determines a second duration of the first signal, the second duration being the duration of the reception of the first signal ahead of the transmission of the uplink frame, uplink signal or uplink channel.

[0267] It should be noted that when the first duration or the second duration is a positive value, it indicates a timing advance, that is, the reception of the first signal is earlier than the reception of the first detection path of the corresponding downlink frame of the reference cell by the first duration, or the reception of the first signal is earlier than the sending of the uplink frame, the uplink signal or the uplink channel by the second duration; when the first duration or the second duration is a negative value, it indicates a timing delay, that is, the reception of the first signal is delayed by the negative of the first duration or its absolute value than the reception of the first detection path of the corresponding downlink frame of the reference cell, or the reception of the first signal is delayed by the negative of the second duration or its absolute value than the sending of the uplink frame, the uplink signal or the uplink channel.

[0268] It should be noted that this case includes three situations. In the first situation, only the first duration and its determination method are regulated (terminal self-estimation or based on network indication); in the second situation, only the second duration and its determination method are regulated (terminal self-estimation or based on network indication); in the third situation, both the first duration and the second duration are regulated, and on the basis of the determination methods of the first duration or the second duration given in the first and second situations (terminal self-estimation or based on network indication), the conversion relationship between the two durations is regulated.

[0269] In this implementation manner, the first network device is responsible for accurately estimating all timing adjustment parameters, which is beneficial to improving the accuracy of timing adjustment parameter estimation, thereby more accurately determining the reception timing of the first signal.

[0270] Optionally, the determining the timing adjustment parameter includes:

[0274] Or, the third timing adjustment parameter is determined according to the timing adjustment amount, the first propagation delay, the second propagation delay, the third propagation delay and the preset parameter, and the third propagation delay is the spatial propagation delay from the first terminal to the first network device.

[0275] In one implementation, specifically, the second timing adjustment parameter is determined by the following formula:

[0276] Among them, A 2is the second timing adjustment parameter, N TA offset To adjust the offset, T c is the delay unit, τ v,a is the first propagation delay, τ a,2 is the second propagation delay, τ v,1 is the third propagation delay, σ is a preset parameter, σ≥0.

[0277] The third timing adjustment parameter is determined by the following formula:

[0278] A 3 ×T′ c ≈τ v,1 +τ a,2 -τ v,a –N TA T c -σ, where A 3 is the third timing adjustment parameter, τ v,a is the first propagation delay, τ a,2 is the second propagation delay, τ v,1 is the third propagation delay, N TA is the timing adjustment amount, σ is a preset parameter, σ≥0, and the preset parameter represents the timing estimation error margin.

[0279] In this implementation manner, the first network device is responsible for accurately estimating all timing adjustment parameters, which is beneficial to improving the accuracy of timing adjustment parameter estimation, thereby more accurately determining the reception timing of the first signal.

[0280] Optionally, the indication information includes second indication information, the timing adjustment parameters include fourth timing adjustment parameters, and the fourth timing adjustment parameters include the spatial propagation delay from the second terminal to the second network device, the spatial propagation delay from the first terminal to the second terminal, and preset parameters.

[0281] In one implementation, the first network device is responsible for accurately estimating some timing adjustment parameters, and the fourth timing adjustment parameter is the timing adjustment parameter accurately estimated by the first network device. Since the first terminal cannot determine the spatial propagation delay from the second terminal to the second network device and the spatial propagation delay from the first terminal to the second terminal, these two parameters are accurately estimated by the first network device and indicated to the first terminal, and the preset parameter is the timing estimation margin.

[0282] In this implementation, the first network device is responsible for accurately estimating part of the timing adjustment parameters, which improves the accuracy of timing adjustment parameter estimation, more accurately determines the reception timing of the signal, and reduces signaling overhead.

[0283] Optionally, the determining the timing adjustment parameter includes:

[0286] The fourth timing adjustment parameter is determined according to the preset parameter, the first propagation delay, and the second propagation delay.

[0287] In one implementation manner, specifically, the fourth timing adjustment parameter may be determined by the following calculation formula:

[0288] A 4 ×T′ c ≈τ a,2 -τ v,a -σ, where A 4 is the fourth timing adjustment parameter, τ a,2 is the second propagation delay, τ v,a is the first propagation delay, σ is a preset parameter, σ≥0, and the preset parameter represents the timing estimation error margin.

[0289] In addition, the fourth timing adjustment parameter may also be:

[0290] A 4 ×T′ c ≈τ v,1 -τ a,2 +τ v,a -σ, where A 4 is the fourth timing adjustment parameter, τ a,2 is the second propagation delay, τ v,a is the first propagation delay, τ v,1 is the propagation delay from the first terminal to the first network device, σ is a preset parameter, σ≥0, and the preset parameter represents the timing estimation error margin.

[0291] The first signaling may be understood as backhaul signaling, and the specific backhaul signaling may be Xn interface signaling or NG interface signaling.

[0292] In this implementation, the first network device is responsible for accurately estimating part of the timing adjustment parameters, which improves the accuracy of timing adjustment parameter estimation, more accurately determines the reception timing of the signal, and reduces signaling overhead.

[0293] Optionally, determining the first propagation delay includes:

[0298] In one implementation, the first network device needs to determine a first propagation delay τ v,a First, the first network device needs to listen to the reference signal sent by the second terminal, so as to determine the spatial propagation delay from the second terminal to the first network device, that is, the fourth spatial propagation delay τ a,1 See also Figure 6 and Figure 7 , the time t at which the reference signal sent by the second terminal arrives at the first network device 8 Than the uplink timing boundary t of the first network device 6 Delayed by a time delay m a,1 , and m a,1 =τ a,1 -τ a,2 , τ a,2 is the second propagation delay. Since the first network device can measure m a,1 , and then obtain τ through the first signaling between the first network device and the second network device a,2 , from which we can calculate τ a,1 =τ a,2 +m a,1 . Afterwards, the first propagation delay is determined.
