[0212] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, both A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the front - and - back associated objects.
[0213] In the embodiments of the present application, the term "a plurality of" means two or more, and other quantifiers are similar.
[0214] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.
[0215] To enable those skilled in the art to better understand the embodiments of the present application, the following explanations are made first:
[0216] I. CJT transmission
[0217] The CJT technology supports coherent transmission of up to 4 TRPs. Assume that the channels between 4 TRPs and the UE are H i , and the signal y received by the UE can be expressed as:
[0218] y = [H1 H2 H3 H4]Wx + n
[0219] Where W is the precoding codeword for joint transmission of 4 TRPs, x is the signal sent by each TRP, and n is the receiver noise. From the above formula, it can be seen that in CJT transmission, the precoding codewords of all TRPs can be written in the form of a joint matrix, that is, the precoding codeword is jointly determined according to the channel conditions of all TRPs.
[0220] II. Measurement reporting technology:
[0221] The current system supports beam measurement reporting and channel state information (CSI) measurement reporting. In CSI reporting, the network side can configure a CSI resource setting for the UE, which includes one or more CSI resource sets. Each CSI resource set contains one or more CSI-RS resources. The UE reports according to the reporting quantity configured by the network side. For example, the reporting quantities configured by the network side are as follows:
[0222]
[0223] Among them, the CSI or synchronization signal block index (ssb-Index) refers to the index of the CSI-RS resource or SSB resource, indicating the subsequent reporting quantity measured by the UE according to the measurement resources corresponding to the index of the CSI-RS resource or SSB resource, such as rank indication (RI), precoding matrix indicator (PMI), channel quality indicator (CQI), etc.
[0224] Embodiments of this application provide a measurement reporting method, a measurement acquisition method, a device, and a readable storage medium. Among them, the method and the device are based on the same inventive concept. Since the principles for solving problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be elaborated.
[0225] As Figure 1 shown, a measurement reporting method provided by an embodiment of this application includes:
[0226] Step 11, the terminal determines multiple measurement objects;
[0227] In this application, the measurement object can be a measurement resource or a measurement resource port, etc. By way of example, 1 measurement resource includes multiple measurement resource ports. The multiple measurement objects can be the multiple measurement resource ports of 1 measurement resource. Or, the multiple measurement objects can be multiple measurement resources or multiple resource ports respectively corresponding to multiple measurement resources. Or, the multiple measurement objects can be multiple measurement resource sets. Another example is that one measurement resource port corresponds to one TRP, and the multiple measurement objects can be represented as multiple TRPs. This application does not limit this.
[0228] Exemplarily, taking the measurement object as a measurement resource. The network side configures multiple measurement resources for the UE. The measurement resources can be CSI-RS resources, or can be SSB resources, TRS resources, etc. The multiple measurement resources can be configured in one measurement resource set (such as a CSI-RS resource set), or can be configured in multiple measurement resource sets. This application does not limit this. One of the measurement resources, or multiple measurement resources in one measurement resource set, corresponds to one TRP.
[0229] Step 12, the terminal sends first delay-related information and first phase-related information corresponding to the multiple measurement objects to the network-side device; wherein, the first delay-related information is related to the first phase-related information.
[0230] Here, the first delay-related information includes a delay or a delay difference, and the first phase-related information includes a phase or a phase difference.
[0231] It should be noted that during reciprocity error measurement, the phase difference is equivalent to the phase difference between the frequency-domain channel impulse responses of two TRPs. During time error measurement, the phase difference is the phase difference between the channel impulse responses of another TRP on different frequency domains when receiving according to the timing of one TRP, which is actually also equivalent to the delay difference between two TRPs.
[0232] In the embodiments of this application, the terminal sends first delay-related information corresponding to multiple measurement objects to the network-side device, and sends first phase-related information related to the first delay-related information. The first delay-related information can be the measured measurement delay, or can be the delay obtained by measurement and then processing. The first phase-related information can be calculated from the measured phase and the corresponding measurement delay. By simultaneously sending the correlated delay and phase, through the preprocessing of the network-side device, the delay difference or phase difference between multiple measurement objects is pre-eliminated, reducing the feedback overhead.
[0233] Optionally, the multiple measurement objects are configured by the network side for the UE. The specific configuration method is implemented by one or more measurement resource sets:
[0234] 1. Configure P1 measurement resource sets, each measurement resource set contains at least one measurement resource, then the UE measures and reports according to at least one measurement resource in each of at least 2 measurement resource sets;
[0235] 2. Configure 1 measurement resource set, which contains multiple measurement resources, then the UE measures and reports according to at least 2 measurement resources;
[0236] 3. Configure one measurement resource set, which includes one measurement resource. Then, the UE performs (time delay difference, frequency difference, phase difference) measurement and reporting based on at least two antenna ports of the measurement resource.
[0237] Optionally, in an embodiment of the present application, the terminal may also send independent first time delay related information and first phase related information to the network side device. For example, the first time delay related information and the first phase related information may be measured separately, or may be measured separately and then processed and reported. Alternatively, the first time delay related information and the first phase related information are reported in one report, but the first time delay related information and the first phase related information are independently quantized.
[0238] The embodiment of the present application provides a time delay difference measurement method: The UE detects the measurement resources (such as SSB resources) sent by two TRPs, and determines the timing of each TRP according to the position distance of the detected autocorrelation peak. For example, the first detected peak corresponds to the reception time of the first TRP, and the second detected peak corresponds to the reception time of the second TRP. Suppose the transmission times of the measurement resources of the two TRPs differ by T1, and the reception peaks differ by T2, then the time delay difference between the two TRPs is T2 - T1.
[0239] The embodiment of the present application provides a phase difference measurement method: When measuring the time error, still taking two TRPs as an example, assuming that TRP 1 is used as a reference, the UE performs downlink reception according to the timing of TRP 1. When the UE receives the measurement resources sent by TRP 2, according to the channel between one reference antenna of TRP 2 and one reference antenna of the UE, the phase difference of the frequency domain channel impulse response of the channel on the same RB (group) is calculated, and this phase difference corresponds to the time difference between TRP 2 and TRP 1.
[0240] Optionally, when the UE of the present application performs measurement reporting, the reporting format of the UE may be:
[0241] First report the first time delay related information, and then report the first phase related information; or,
[0242] When dividing multiple measurement resources into multiple measurement resource combinations, the first time delay related information and the first phase related information corresponding to one measurement resource (combination) may be reported first, and then the first time delay related information and the first phase related information corresponding to other measurement resources (combinations) may be reported.
[0243] In an optional embodiment, the method of the present application further includes:
[0244] The terminal sends the amplitudes corresponding to the multiple measurement objects to the network side device.
[0245] In the embodiments of the present application, when the terminal performs measurement reporting to the network-side device, it may report the amplitudes corresponding to multiple measurement objects while reporting the first delay-related information and the first phase-related information. The present application reports at least one of the first delay-related information, the first phase-related information, the amplitude corresponding to the first delay-related information, and the amplitude corresponding to the first phase-related information. By this method, the time difference, phase difference, reciprocity error, etc. between multiple TRPs can be accurately eliminated.
[0246] Exemplarily, when the first delay-related information includes a delay difference and the first phase-related information includes a phase difference, and the UE reports the delay difference, the phase difference, and the amplitude, the reporting format of the UE may be:
[0247] Report the delay difference and the phase difference first, and then report the amplitude (the order of the phase difference and the amplitude can be reversed); or,
[0248] Report the delay difference, the phase difference, and the amplitude corresponding to a measurement resource (combination), and then report the delay difference, the phase difference, and the amplitude corresponding to other measurement resource combinations.
[0249] Optionally, when the terminal performs measurement reporting to the network-side device, it may report at least two of the first delay-related information, the first phase-related information, and the amplitude between multiple measurement objects. Exemplarily, the present application may report the first delay-related information and the first phase-related information; or may perform measurement reporting on the first delay-related information and the amplitude, etc.
[0250] In an optional embodiment, the method of the present application further includes:
[0251] The terminal determines one or more second phase-related information of the multiple measurement objects, and second delay-related information corresponding to the second phase-related information;
[0252] The terminal performs delay removal processing on the second phase-related information based on the second delay-related information to obtain third phase-related information;
[0253] The terminal obtains the first phase-related information by quantifying the third phase-related information.
[0254] In an embodiment of the present application, the first phase-related information is the phase (or phase difference) after removing the influence of time delay (or time delay difference). After the terminal in the present application determines one or more second phase-related information, it can determine the second time-delay-related information corresponding to the second phase-related information, and the one or more second phase-related information can correspond to one second time-delay-related information. The present application performs time-delay processing on the second phase-related information based on the second time-delay-related information to obtain third phase-related information, which is beneficial to eliminating possible errors and interferences and improving the reliability and accuracy of measurement results; the terminal quantizes the third phase-related information to obtain first phase-related information that is correlated with the first time-delay-related information, and reporting the quantized first phase-related information can reduce transmission consumption.
[0255] Optionally, the terminal performs time-delay processing on the second phase-related information based on the second time-delay-related information to obtain third phase-related information, including:
[0256] The terminal subtracts a first value from the second phase-related information to obtain the third phase-related information;
[0257] Wherein, the first value is calculated by the formula the second phase-related information mod(2πf0τ,2π); wherein, τ is the second time-delay-related information; f0 is a configured frequency value, or a center frequency value corresponding to a specific transmission resource, or a frequency value determined by the center frequency value corresponding to the first transmission resource, subcarrier spacing, resource granularity, and subcarrier format included in each resource block.
[0258] Here, the transmission resource is a plurality of resources obtained by dividing the available resources according to a preset rule, and the transmission resource can be understood as a sub-band. For example, the available resources include 200 PRBs, which are divided into groups of 8 PRBs, and 25 sub-bands can be obtained. Or, the available resources include 200 PRBs, which are divided into groups of 2 PRBs, and 100 sub-bands can be obtained. The sub-band granularity for reporting the time-delay-related information and the phase-related information can be slightly smaller than the sub-band granularity for other CSI reporting.
[0259] Optionally, the UE reports the sub-band granularity so that the network device can perform subsequent processing after receiving the first phase-related information.
[0260] Taking the transmission resource as a sub-band as an example, f0 in the present application can include any of the following forms:
[0261] Option1: f0 is a frequency value configured by a high-layer parameter.
[0262] Option 2: f0 is the center frequency value corresponding to the j-th sub-band, which is determined by the high-layer parameters "absoluteFrequencyPointA" and "offsetToPointA", and predefined formulas (including sub-carrier spacing or sub-band spacing, etc.). For example, the center frequency value of the first sub-band is the value configured by absoluteFrequencyPointA + the value configured by offsetToPointA + C, where the value C is the offset value between the measurement resource and the center frequency of SIB transmission, and the value C is configured by high-layer signaling.
[0263] Option 3: f0 is the center frequency value corresponding to the first sub-band, i.e., f1; all sub-bands determine the phase (difference) based on the same center frequency, where the determination method of f1 is the same as that of option 1 and option 2.
[0264] Option 4: f0, which is the center frequency of the first sub-band, is directly configured by high-layer parameters, and the center frequencies of other sub-bands are determined by formulas. For example, for the j-th (j>1) sub-band, the center frequency where f1 is the center frequency of the first sub-band, SCS is the sub-carrier spacing, such as 15 kHz, 30 kHz, etc., G is the granularity of the sub-band, with the unit of transmission block RB or physical transmission block PRB, such as a sub-band contains 0.5 RB, etc., and is the number of sub-carriers contained in one RB.
[0265] For example, at least f1, which is the center frequency of the first sub-band, is directly configured by high-layer parameters, and the center frequencies of other sub-bands are determined by formulas, such as
[0266] In the embodiments of the present application, the second phase-related information is used to obtain a first value by mod(2πf0τ,2π), and then the terminal subtracts this first value from the second phase-related information to obtain the third phase-related information, which can ensure that the phase (difference) is small. Based on this, a more refined codebook is designed to ensure the accurate reporting of the phase (difference).
[0267] It should be noted that the form of the phase-related information can include multiple types. Form 1: 2πf j τ, with the unit of radian; Form 2: Form 3: Above, the determination method of the third phase-related information is applicable to the case where the second phase-related information is in Form 1. When the second phase-related information is in Form 2, the terminal can obtain the third phase-related information by dividing the second phase-related information by the second value, where the second value is τ is the second delay-related information, and f0 is the same as f0 of the first value. When the second phase-related information is in Form 3, the terminal can be based on Dividing the second phase-related information element to obtain third phase-related information, where τ is the second time-delay related information, and f0 is the same as f0 of the first value.
[0268] Optionally, the terminal obtains the first phase-related information by quantifying the third phase-related information, including:
[0269] The terminal quantifies the third phase-related information through a quantization codebook to determine the first phase-related information.
[0270] In the embodiments of the present application, the quantization codebook can be a configured or pre-configured codebook. The transmission type of the quantization codebook can be a codebook for coherent transmission or a codebook for non-coherent transmission. The present application does not limit this. The present application quantifies the third phase-related information through a quantization codebook, or can also quantify the third phase-related information through a first quantization method to determine the first phase-related information.
[0271] Exemplarily, when the third phase-related information represents the phase (difference) in the following form, taking the first time-delay related information such as time-delay difference and the first phase-related information such as phase difference corresponding to 2 TRPs fed back at one time as an example, if the UE feeds back a time-delay (difference) corresponding to 2 TRPs, denoted as τ, the phase (difference) corresponding to τ can have the following several forms:
[0272] Form 1: 2πf j τ, in radians;
[0273] Form 2:
[0274] Form 3:
[0275] Among them, Form 3 is in the form of a vector. 1 indicates that the phase (difference) between TRP 1 and TRP 1 is 0, indicates that the phase (difference) between TRP 2 and TRP 1 is Substantially, only Form 1 is the phase (difference). Using Forms 2 and 3 for feedback is to reduce the feedback overhead. For example, through the feedback of the precoding codewords in the precoding codebook (corresponding to Form 3), both the base station and the UE can determine the corresponding phase (difference) according to the precoding codewords.
[0276] The above-mentioned first quantization method: Since the time-delay difference and the phase difference correspond to each other and reflect the time-delay difference or phase difference between 2 TRPs from different dimensions, the phase difference value obtained by subtracting the frequency-domain phase corresponding to the measured time-delay difference from the measured frequency-domain phase difference (such as corresponding to The value will be smaller. One method is to let the UE feedback the phase range used for quantifying the frequency-domain phase difference, also known as the reporting range, such as the range [a, b], [-a, b] or [0, b], with the unit being radians or degrees. Among them, the values of a or b are positive, and the values are configured by the network side, or pre-specified in the protocol, or reported by the UE to the network side. After determining the reporting range, the UE quantifies the third phase-related information according to the quantization granularity corresponding to the phase range, and reports it after obtaining the first phase-related information. Another approach is to quantify the third phase-related information using a uniform quantization method, such as the reporting range and quantization granularity are both pre-specified in the protocol.
[0277] Optionally, the third phase-related information is in Form 2 When representing the phase (difference), the present application can also quantify the third phase-related information through a quantization codebook or a second quantization method to determine the first phase-related information.
[0278] Second quantization method: Similar to the first quantization method, when the phase (difference) is in Form 2 the UE can report the phase difference in the exponent domain (such as corresponding to the value or the value). At this time, the phase range used can be [c, d] or [0, d], where the values of c or d are positive, and the values are configured by the network side device, or pre-specified in the protocol, or reported by the UE to the network side device. After determining the reporting range, the UE reports according to the quantization granularity corresponding to the reporting range. Another approach is that the reporting range and quantization granularity are both pre-specified in the protocol.
[0279] In a specific implementation provided by the present application, the determination method of the first phase-related information is:
[0280] The terminal reports a first delay-related information such as delay (difference) (corresponding to 2 TRPs or 2 measurement resources). When the delay (difference) is τ, assuming that the first delay-related information is the second delay-related information corresponding to the second phase-related information, then the reported first phase-related information such as phase (difference) is the second phase-related information, that is, the measurement phase (difference), subtracting the first value (the second phase-related information mod(2πf0τ, 2π)) to determine the third phase-related information, and then determining according to the value quantified by the first quantization method; or the first phase-related information such as phase (difference) is the second phase-related information, that is, the measurement value (equivalent to the value in the exponent domain) divided by and then according to the value quantified by the first codebook.
[0281] In another specific implementation provided by the present application, the determination method of the third phase-related information is:
[0282] The terminal reports first latency-related information such as multiple latencies (differences) (corresponding to multiple TRPs or measurement resources), and the reported second phase-related information such as phase (difference) is the value obtained by subtracting the corresponding second latency-related information such as the phase value corresponding to the latency (difference) (e.g., the second phase-related information mod(2πf j τ, 2π)) from the measurement phase (difference), and then quantifying according to the first quantization method; or the first phase-related information such as phase (difference) is the value obtained by dividing the second phase-related information, i.e., the measurement value, by the corresponding frequency-domain value corresponding to the second latency-related information such as latency (difference) (equivalent to having a value in the exponential domain), and then quantifying according to the quantization codebook or the second quantization method.
[0283] Further, in an alternative embodiment of the present application, the above quantization codebook includes at least one of the following:
[0284] The first codebook W1,
[0285] The second codebook W2, wherein the value of P is configured by a higher-layer parameter, and P is less than or equal to N;
[0286] The third codebook W3,
[0287] The fourth codebook W4, wherein, N p has a value configured by a higher-layer parameter or predefined in the protocol, and p = 1, 2,..., K - 1;
[0288] The fifth codebook W5, wherein the value of P is configured by a higher-layer parameter, and P is less than or equal to N;
[0289] The sixth codebook W6, wherein, P q has a value configured by a higher-layer parameter, and q = 1, 2,..., K - 1;
[0290] wherein, N is a positive integer, and K is determined by the number of measurement objects.
[0291] It should be noted that in the embodiments of the present application, when quantifying the third phase-related information through the quantization codebook, the terminal will feedback the precoding codeword in the quantization codebook to the network-side device, and both the base station and the UE can determine the corresponding phase (difference) according to the precoding codeword. Among them, the quantization codebook can also be understood as a precoding codebook.
[0292] In the embodiments of the present application, when the number of measurement objects (such as the number of TRPs, the number of measurement resources, or the number of measurement resource ports) is 2, the quantization codebook can be represented in the form of a first codebook, where i in the first codebook represents the precoding codeword index. For example, when the precoding codebook contains 2 bits, the corresponding precoding codeword set can be represented as shown in Table 1 below:
[0293] Table 1:
[0294]
[0295]
[0296] Among them, Codebook index represents the codebook index; Number of layers represents the number of network layers corresponding to the precoding codeword.
[0297] Furthermore, when the precoding codebook contains 3 bits, the corresponding precoding codeword set can be represented as shown in Table 2 below:
[0298] Table 2:
[0299]
[0300] In this embodiment, the number of network layers corresponding to the precoding codeword can be restricted to 1, such as for the network side to recover the downlink channel information according to the precoding codeword.
[0301] In one implementation, the phase difference reported by the UE is after differential operation, so only some precoding codewords can be reported. One method is to configure a subset restriction for UE measurement reporting, such as using N bits to configure which precoding codewords the UE can report through bit mapping; for another example, let i take values of 0, 1, 2,..., P - 1, where the value of P is configured by a high-layer parameter.
[0302] Another method is to report in the form of the above-mentioned second codebook. Among them, the value of P in the above-mentioned second codebook is configured by a high-layer parameter.
[0303] When the number of measurement objects (such as the number of TRPs, the number of measurement resources, or the number of measurement resource ports) is 2, the quantization codebook used can be represented in the form of the above-mentioned third codebook or the above-mentioned fourth codebook.
[0304] Among them, in the third codebook, the quantization method for each phase difference is the same, that is, the phase value distribution corresponding to the phase difference is the same; in the fourth codebook, the phase value distribution corresponding to each phase difference can be different.
[0305] Similarly, the phase difference can also be reported by restricting the codebook subset or using a new codebook to reduce the feedback overhead. The quantization codebook can be in the form of the fifth codebook or the sixth codebook described above.
[0306] Among them, the value of P in the fifth codebook or P k (k = 1, 2, …, K-1) is configured by high-layer parameters.
[0307] Exemplarily, when measuring the reciprocity error, still taking 2 TRPs as an example, each TRP selects one reference antenna, and the UE selects one reference antenna. Then the UE first measures the frequency-domain channel impulse response of the equivalent channel formed by the UE reference antenna and the TRP reference antenna, assumed to be H = [h1 h2]. Then the UE multiplies with H according to the first codebook, and selects the optimal precoding matrix in the codebook according to the principle of the largest second norm. For example, the optimal precoding matrix is Then it means that the phase difference between the 2 TRPs is or or (corresponding to different phase difference forms). When the number of TRPs is 4, the phase difference measurement method is similar, and the UE calculates the corresponding phase difference according to the third to sixth codebooks.
[0308] Optionally, the terminal sends the first phase-related information corresponding to the multiple measurement objects to the network-side device, including:
[0309] The terminal jointly reports the first phase-related information related to the same first delay-related information; or,
[0310] The terminal jointly reports the first phase-related information corresponding to the measurement resources of the same measurement object; or,
[0311] The terminal jointly reports the first phase-related information corresponding to the multiple first delay-related information reported; or,
[0312] The terminal jointly reports the multiple first phase-related information corresponding to the same sub-band; or,
[0313] The terminal jointly reports the first phase-related information of the same type; or,
[0314] The terminal jointly reports all the determined first phase-related information.
[0315] In the embodiments of the present application, the reporting form of jointly reporting the first phase-related information corresponding to the multiple measurement objects to the network-side device includes at least one of the following:
[0316] (1) The terminal jointly reports the first phase correlations related to the same first time-delay related information. For example, the terminal can jointly report the phase differences corresponding to each determined time-delay difference.
[0317] (2) The terminal jointly reports the first phase correlation information corresponding to the same measurement object. For example, the terminal can jointly report the phase differences corresponding to the same measurement resource (or a measurement resource combination, which is a measurement resource combination formed by combining multiple measurement resources).
[0318] (3) The terminal jointly reports the first phase correlation information corresponding to multiple reported first time-delay related information. For example, the phase differences corresponding to multiple time-delay differences reported by the UE can be jointly reported.
[0319] (4) The terminal jointly reports multiple first phase correlation information corresponding to the same sub-band. For example, the terminal jointly reports the phase differences corresponding to the same sub-band.
[0320] (5) The terminal jointly reports the first phase correlation information of the same type. For example, the first phase correlation information of the same type, such as type one, can be jointly reported. In this application, the phase differences between different types can also be jointly reported. For example, the phase differences between type two and type three are jointly reported, and type two and type three are different.
[0321] (6) The terminal jointly reports all the determined first phase correlation information. For example, the terminal jointly reports all the phase differences.
[0322] In a specific implementation manner of this application, when sending the first phase correlation information corresponding to multiple measurement objects to the network-side device, the following phase difference reporting method can be adopted. Here, the first phase correlation information is taken as the phase difference, and the first time-delay related information is taken as the time-delay difference for illustration:
[0323] Method 1: The phase differences corresponding to each time-delay difference or each measurement resource (combination) can be jointly reported.
[0324] For example, the phase differences corresponding to measurement resource 1 and measurement resource 2 are Define the minimum phase as Then when reporting the phase, the UE can subtract from all the phase values and then report them to reduce the feedback overhead;
[0325] Another example, the phase differences corresponding to measurement resource 1 and measurement resource 2 are Define the minimum phase as Then when reporting the phase, the UE can divide all the phase values by Report it later to reduce the feedback overhead;
[0326] For another example, the phase difference corresponding to measurement resource 1 and measurement resource 2 is Define the minimum phase as Then when reporting the phase, the UE can divide all phase value points by Report it later to reduce the feedback overhead; or The corresponding precoding matrix indices are s, j, …, p, etc. Define the minimum phase as Then when reporting the phase, the UE can subtract from all phase value corresponding precoding indices and report it later to reduce the feedback overhead.
[0327] Method 2: The phase differences corresponding to multiple time delays reported by the UE can be jointly reported. For example, combine the phase differences corresponding to all time delays in one report to determine the minimum phase as And remove the influence of and then report.
[0328] Method 3: Joint reporting is performed among multiple phase differences corresponding to one sub-band. For example, the number of measurement resources is 4, the UE determines 3 phase differences for each sub-band, and each phase difference corresponds to 2 TRPs (or measurement resources or measurement resource ports). Then the UE can jointly report the 3 phase differences for each sub-band, that is, jointly determine the minimum phase as And remove the influence of and then report.
[0329] Method 4: Joint reporting is performed among different types of phase differences. For example, the UE reports the phase difference for time asynchrony elimination and the phase difference for reciprocity error elimination. Then joint reporting is performed within different types of phase differences. The UE determines the minimum phase among all phase differences within one type of phase difference as And remove the influence of and then report.
[0330] Method 5: All phase differences are jointly reported. For example, the UE determines the minimum phase among all phase differences as And remove the influence of and then report.
[0331] Optionally, in each of the above phase difference joint reporting methods, the UE determines the maximum phase difference in one joint report as And remove the influence of and then report.
[0332] Optionally, the UE will a numerical value or report the numerical value to the network side; optionally, the UE will or the corresponding sub - band index (or RB index or sub - carrier index) or the corresponding time - delay difference index (such as the index value determined according to the reporting order of multiple time - delay differences, and the time - delay difference index of the i - th report is i), or the corresponding measurement resource (combination) index to the network side.
[0333] Optionally, the feedback granularity of the phase difference corresponding to each time - delay difference is different, that is, the feedback granularity of the phase difference is determined according to the magnitude of each time - delay difference or the numerical value of the phase difference. For example, if the UE reports 3 time - delay differences, the feedback granularities of the phase differences corresponding to each time - delay difference are K1 RBs, K2 RBs, and K3 RBs respectively; in addition, the feedback granularities of the phase differences corresponding to multiple time - delay differences can also be made the same. For example, the feedback granularity is determined according to the time - delay difference with the smallest feedback granularity or the corresponding phase difference to ensure that the reporting overheads of the phase differences corresponding to each time - delay difference are the same.
[0334] In the embodiments of the present application, after the joint reporting of the time - delay difference and the phase difference, differential reporting can be further performed on the phase difference corresponding to each time - delay difference, the phase difference corresponding to all time - delay differences, or the phase difference corresponding to each sub - band.
[0335] Optionally, the method of the present application further includes:
[0336] The terminal determines the maximum phase value or the minimum phase value in a set of phase - related information reported jointly, and pre - processes each of the first phase - related information in the set of phase - related information reported jointly based on the maximum phase value or the minimum phase value.
[0337] In the embodiments of the present application, the terminal first determines the maximum phase value or the minimum phase value in a set of phase - related information reported jointly. For example, the minimum phase value is represented by and the maximum phase value is represented by, for example, Pre - processing each of the first phase - related information in the set of phase - related information reported jointly can specifically be subtracting or dividing all the phases in the set of phase - related information by the minimum phase value or the maximum phase value and then reporting the resources to the network - side device.
[0338] Optionally, the method of the present application further includes:
[0339] The terminal sends at least one of the following to the network - side device:
[0340] The maximum phase value or minimum phase value of each group of phase-related information;
[0341] The subband index corresponding to the maximum phase value or minimum phase value in each group of phase-related information;
[0342] The first delay-related information index corresponding to the maximum phase value or minimum phase value in each group of phase-related information;
[0343] The measurement resource index corresponding to the maximum phase value or minimum phase value in each group of phase-related information.
[0344] In the embodiments of the present application, the UE may a numerical value or a numerical value to the network-side device; the UE may also or the corresponding subband index (or RB index or subcarrier index) or the corresponding delay difference index (such as the index value determined according to the reporting order of multiple delay differences, and the delay difference index reported for the i-th time is i), or the corresponding measurement resource (combination) index to the network-side device.
[0345] Optionally, the amplitudes corresponding to the multiple measurement objects include at least one of the following:
[0346] The weighted value of the first delay-related information;
[0347] The weighted value of the first phase-related information;
[0348] The weighting coefficient of the first delay-related information;
[0349] The weighting coefficient of the first phase-related information.
[0350] In the present application, the amplitude is correlated with the first delay-related information or with the first phase-related information. In one possible implementation, the first phase-related information is determined according to the first delay-related information, and the weighting coefficient of the first delay-related information and the weighting coefficient of the first phase-related information may be coefficients with equal numerical values. When reporting the delay and amplitude, the frequency-domain equivalent phase difference can be determined through the weighting coefficient of the first delay-related information for time asynchrony cancellation or reciprocity error cancellation. When reporting the delay, phase and amplitude, the frequency-domain equivalent phase difference can be determined through the weighting coefficient of the first delay-related information and / or the weighting coefficient of the first phase-related information for time asynchrony cancellation or reciprocity error cancellation.
[0351] Exemplarily, the first time delay related information is exemplified by a time delay difference, and the measurement resource is exemplified by the TRP. In some cases, multiple time delay differences jointly determine the channel information between the TRP and the UE. For example, the UE reports 4 time delay differences, which respectively represent the time delay difference of the strongest path between TRP 1 and TRP 2, the time delay difference between the strongest path of TRP 1 and the second strongest path of TRP 2, the time delay difference between the second strongest path of TRP1 and the strongest path of TRP 2, and the time delay difference of the second strongest path between TRP 1 and TRP 2. In order to enable the network side device to recover the frequency domain channel information according to multiple time delay differences, the UE can also additionally report the weighting coefficients corresponding to multiple time delay differences, that is, the weighting coefficients (i.e., amplitudes) of the first time delay related information.
[0352] The UE reports multiple time delay differences for every 2 TRPs: the reporting form is one or more time delays (differences) and one or more weighting values (coefficients), where the number of time delays (differences) and / or the number of weighting values (also called the number of weighting value coefficients, or the number of strongest paths) are configured by the network side device or reported by the UE. For example, the network side device configures a detection threshold value, and when the received signal strength exceeds the threshold value, the time delay difference between this path and other paths is reported, where the received signal strength of other paths also needs to exceed a certain threshold value; or, when the time delay difference corresponding to 2 measurement resources is greater than a certain threshold value, the UE will report the corresponding time delay difference, and when the time delay difference is less than the threshold value, it will not be reported. In addition, the UE only reports the time delay differences corresponding to different measurement resources (i.e., the time delay differences between different TRPs), and does not report the time delay differences between different paths of the same measurement resource.
[0353] Optionally, the terminal sending the amplitude corresponding to the multiple measurement objects to the network side device includes:
[0354] The terminal jointly reports the amplitudes corresponding to the measurement resources of the same measurement object; or,
[0355] The terminal jointly reports the amplitudes of the same type; or,
[0356] The terminal jointly reports the amplitudes corresponding to the same first time delay related information; or,
[0357] The terminal jointly reports the amplitudes corresponding to the same first phase related information; or,
[0358] The terminal jointly reports the amplitudes corresponding to all the determined first time delay related information; or,
[0359] The terminal jointly reports the amplitudes corresponding to all the determined first phase related information; or,
[0360] The terminal reports all the amplitudes.
[0361] In the embodiments of the present application, the terminal may report the first delay-related information and the amplitude. Specifically, among the various manifestations of the following amplitude, the first delay-related information includes a delay difference, and the delay difference is 2πf j represented by τ, where 2πf j the unit of τ is radians, or the delay difference is represented by .
[0362] In a specific implementation manner, the form of reporting the first delay-related information and the amplitude includes at least one of the following:
[0363] (1), the weighting coefficient A i , where A i corresponds to the i-th delay difference; when the network-side device receives the delay difference and the weighting coefficient reported by the UE, according to the following formula A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) to determine the frequency-domain equivalent phase difference for time asynchrony cancellation or reciprocity error cancellation. Where τ i corresponds to the i-th delay difference, and f j is the frequency corresponding to the j-th subcarrier or the j-th RB or the j-th subband, and the determination method of f0 is the same as the above determination method of f0;
[0364] (2), the weighting coefficient B i , where B i corresponds to the i-th delay difference; when the network-side device receives the delay difference and the weighting coefficient reported by the UE, according to the following formula to determine the frequency-domain equivalent phase difference for time asynchrony cancellation or reciprocity error cancellation;
[0365] (3), the weighting coefficient C i , where C i corresponds to the i-th delay difference; when the network-side device receives the delay difference and the weighting coefficient reported by the UE, according to the following formula C1τ1 + C2τ2 + C3τ3 + C4τ4 to determine the equivalent delay difference for time asynchrony cancellation;
[0366] (4), the weighting value A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) or the weighting value The corresponding amplitude (i.e., D) or weighted value C1τ1 + C2τ2 + C3τ3 + C4τ4 is calculated by the UE and reported to the network device;
[0367] (5), the weighted value A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) and the weighting coefficient A i ;
[0368] (6), the amplitude (i.e., D) corresponding to the weighted value and the weighting coefficient B ; i ;
[0369] (7), the weighted value C1τ1 + C2τ2 + C3τ3 + C4τ4 and the weighting coefficient C i .
[0370] Among them, the 2πf j τ k component in the weighted value needs to be modulo 2π, k is the number of corresponding time delay (difference), or modulo 2π after obtaining the weighted value according to the above formula.
[0371] Furthermore, when reporting the time delay difference and amplitude, when only reporting the time delay difference and amplitude for 2 TRPs, the UE also needs to further report whether the time delay difference is the time delay difference of measurement resource 1 relative to measurement resource 2 or the time delay difference of measurement resource 2 relative to measurement resource 1, such as using 1 bit for indication. When the time delay difference is the time delay difference of measurement resource 1 relative to measurement resource 2, it means that measurement resource 2 is received by the UE first. Then, after receiving the weighted value and / or weighting coefficient reported by the UE, the network device determines the frequency-domain equivalent phase difference corresponding to multiple time delays, and then pre-compensates the downlink transmission signal corresponding to measurement resource 1, so that the signals transmitted by the TRPs corresponding to the 2 measurement resources reach the UE simultaneously. Or, in the TDD case, the network device can determine the frequency-domain equivalent phase difference according to the time delay difference reported by the UE, and determine the frequency-domain channel corresponding to each RB or sub-band, such as Furthermore, estimate the precoding matrix of each sub-band, so that the estimated precoding corresponds to the channel information in the case of non-synchronization.
[0372] The UE reports multiple time delays (differences) for multiple TRPs (one or more time delay differences correspond to every 2 measurement resources):
[0373] When the number of TRPs is greater than 2, the UE reports multiple groups of time delay differences. Each group of time delay differences corresponds to a TRP or a measurement resource (combination). The reporting method of each group of time delay differences, weighted value, and / or weighted coefficient is similar to the time delay difference reporting method corresponding to 2 TRPs. The number of weighted coefficients can be predefined in the protocol or pre-configured by the network-side device for the UE.
[0374] After receiving the report from the UE, the network-side device determines the frequency-domain equivalent phase differences corresponding to multiple time delays, compensates the transmission signals of the TRPs, so that the signals transmitted by multiple TRPs reach the UE simultaneously; alternatively, the network-side device constructs the channel information of each RB (or sub-band) according to the time delay difference and amplitude. For example, the channel information corresponding to 4 TRPs is Furthermore, the precoding matrix of each sub-band is estimated, and the estimated precoding corresponds to the channel information in the case of out-of-sync.
[0375] Optionally, when the UE reports the time delay difference and amplitude to the network-side device for resource reporting, the reporting format of the UE can be as shown in Table 3 below:
[0376] Table 3:
[0377]
[0378] Optionally, the reporting format for the UE to report resources to the network-side device can also be as shown in the following Table 4, where T represents the number of time delay differences.
[0379] Table 4:
[0380]
[0381]
[0382] Optionally, the UE can also report the indication of the measurement resource (combination).
[0383] Optionally, when the amplitude adopts the above-mentioned weighted value or weighted coefficient, the reporting format of the UE can be:
[0384] Report the time delay difference first, and then report the amplitude;
[0385] Report the time delay difference and amplitude corresponding to one measurement resource (combination), and then report the time delay difference and amplitude corresponding to other measurement resource combinations.
[0386] In another specific implementation manner, the reporting forms of the first time delay-related information, the first phase-related information, and the amplitude include at least one of the following:
[0387] (1), weighted value coefficient A i , where A iCorresponding to the i-th time delay difference; when the network side receives the time delay difference and the weighting coefficient reported by the UE, according to the following formula A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4), the frequency-domain equivalent phase difference is determined for time asynchrony elimination or reciprocity error elimination. Where τ i corresponds to the i-th time delay difference, and f j is the frequency corresponding to the j-th subcarrier or the j-th RB or the j-th subband, where the determination method of f j is the same as the above determination method of f0;
[0388] (2), Weighting value coefficient B i , where B i corresponds to the i-th time delay difference; when the network side receives the time delay difference and the weighting coefficient reported by the UE, according to the following formula the frequency-domain equivalent phase difference is determined for time asynchrony elimination or reciprocity error elimination;
[0389] (3), The weighting value A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) or the amplitude value (i.e., D) corresponding to the weighting value is calculated by the UE and reported to the network side;
[0390] (4), The weighting value A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) and the weighting coefficient A i ;
[0391] (5), The amplitude value (i.e., D) corresponding to the weighting value and the weighting coefficient B i ;
[0392] Among them, the 2πf j τ k component in the weighting value needs to take the modulo of 2π, k is the corresponding number of time delays (differences), or take the modulo of 2π after obtaining the weighting value according to the above formula.
[0393] In fact, the amplitude can be regarded as the combination coefficient between multiple time delay differences or the combination coefficient between multiple phase differences. Therefore, the method of reporting the amplitude corresponding to the time delay difference and the method of reporting the time delay corresponding to the phase difference are similar. When the UE needs to report both the amplitude (combination coefficient) corresponding to multiple time delay differences and the amplitude (combination coefficient) corresponding to multiple phase differences, the amplitude corresponding to the time delay difference and the amplitude corresponding to the phase difference can be quantized separately.
[0394] Optionally, when the amplitude adopts the above-mentioned weighted value or weighted coefficient, the reporting format of the UE can be:
[0395] First report the time delay difference and the phase difference, and then report the amplitude (the order of the phase difference and the amplitude can be reversed);
[0396] Report the time delay difference, phase difference and amplitude corresponding to a measurement resource (combination), and then report the time delay difference, phase difference and amplitude corresponding to other measurement resource combinations.
[0397] Correspondingly, when both the time asynchrony error cancellation and the reciprocity error cancellation are supported, the network-side device can configure the purpose of this measurement report, or at least configure the reporting purpose of the phase difference. The following at least one method is used for processing:
[0398] Method 1: The UE reports a group of time delay differences and a group of phase differences, where the time delay difference is used for time asynchrony cancellation, and the phase difference is used for reciprocity error cancellation;
[0399] Method 2: The UE reports a group of time delay differences and two groups of phase differences, where the time delay difference and the first group of phase differences are used for time asynchrony cancellation, and the second group of phase differences is used for reciprocity error cancellation;
[0400] Method 3: The UE reports two groups of time delay differences and two groups of phase differences, where the first group of time delay differences and the first group of phase differences are used for time asynchrony cancellation, and the second group of time delay differences and the second group of phase differences are used for reciprocity error cancellation, or the first group of time delay differences and the first group of phase differences are used for reciprocity error cancellation, and the second group of time delay differences and the second group of phase differences are used for time asynchrony cancellation.
[0401] Optionally, the method of this application further includes:
[0402] The terminal determines the maximum amplitude in a group of amplitudes reported jointly, and preprocesses each amplitude in the group of amplitudes reported jointly based on the maximum amplitude.
[0403] In the embodiment of this application, the terminal determines the maximum amplitude in a group of amplitudes reported jointly, and this maximum amplitude can be represented by d max and based on the maximum amplitude d max , each amplitude in the group of amplitudes reported jointly is divided by the maximum amplitude d maxReport it later to minimize the feedback overhead.
[0404] Optionally, the amplitude reported by the UE may correspond to the first delay-related information (delay difference), or may correspond to the first phase-related information (phase difference). In addition, the amplitude also corresponds to the measurement resource (combination).
[0405] Optionally, when the terminal reports the amplitude to the network-side device, any of the following methods may be used:
[0406] Report the amplitude corresponding to each measurement resource (combination) separately.
[0407] Report the amplitudes of each type separately.
[0408] Report the amplitude corresponding to each delay difference separately.
[0409] Report the amplitude corresponding to each phase difference group separately.
[0410] Report the amplitudes corresponding to all delay differences separately.
[0411] Report the amplitudes corresponding to all phase differences separately.
[0412] Optionally, the method of this application further includes:
[0413] The terminal sends the following at least one item to the network-side device:
[0414] The maximum amplitude of each group of amplitudes;
[0415] The subband index corresponding to the maximum amplitude in each group of amplitudes;
[0416] The delay difference index corresponding to the maximum amplitude in each group of amplitudes;
[0417] The measurement resource index corresponding to the maximum amplitude in each group of amplitudes.
[0418] In this application, the UE reports the d values corresponding to each measurement resource (combination) to the network-side device; the UE also reports the subband index (or RB index or subcarrier index) corresponding to d to the network-side device. s,max The UE also reports the d s,max corresponding subband index (or RB index or subcarrier index) to the network-side device.
[0419] In the embodiment of this application, when reporting the amplitude, according to different amplitude forms, the terminal may use at least one of the following forms to send the amplitude to the network-side device. In Methods 1 to 7 of the following amplitude reporting methods, the first delay-related information is exemplified by the delay difference, and the first phase-related information is exemplified by the phase difference:
[0420] Method 1: Report the amplitude corresponding to each measurement resource (combination) separately.
[0421] First, determine the maximum amplitude among the amplitudes corresponding to each measurement resource (combination) (such as d s,max ), where s is the index of the measurement resource (combination). The measurement resource (combination) is predefined or configured by the network-side device. Divide all the amplitudes in the measurement resource (combination) s by d s,max and then perform Q-bit quantization. When Q = 1, 2, 3, and 4, quantization is performed according to Tables 5 - 8.
[0422] Table 5:
[0423]
[0424] Table 6:
[0425]
[0426]
[0427] Table 7:
[0428]
[0429] Table 8:
[0430]
[0431] When a measurement resource (combination) includes both the amplitude corresponding to the time delay difference and the amplitude corresponding to the phase difference, or includes both the amplitude corresponding to the time asynchrony elimination and the amplitude corresponding to the reciprocity error elimination, the reporting can be performed separately for different types of amplitudes, that is, see Method 2 of the amplitude reporting below.
[0432] Method 2: Report each type of amplitude separately.
[0433] For example, report the amplitudes corresponding to the time delay difference separately, report the amplitudes corresponding to the phase difference separately, report the amplitudes corresponding to the time asynchrony elimination separately, and report the amplitudes corresponding to the reciprocity error elimination separately.
[0434] If there are multiple measurement resources (combinations) corresponding to each amplitude type, first determine the maximum value among the amplitudes corresponding to all the measurement resources (combinations) (such as d max ), divide all the amplitudes corresponding to one amplitude type by d max and then perform Q-bit quantization. When Q = 1, 2, 3, and 4, quantization is performed according to Tables 1 - 4. Optionally, the UE reports the d max value corresponding to each amplitude type to the network-side device. Optionally, the UE also reports d maxThe corresponding measurement resource (combination) and / or sub-band index (or RB index or sub-carrier index) are reported to the network-side device.
[0435] Method 3: The amplitudes corresponding to each time delay difference are reported separately.
[0436] First, determine the maximum value among the amplitudes corresponding to each time delay difference (such as d max ), then divide all the amplitudes corresponding to this time delay difference by d max and then perform Q-bit quantization. Optionally, the UE reports the value of d max to the network-side device. Optionally, the UE also reports the sub-band index (or RB index or sub-carrier index) corresponding to d max , or the corresponding time delay difference index (such as the index value determined according to the reporting order of multiple time delay differences, and the time delay difference index of the i-th reported is i), or the corresponding measurement resource (combination) index to the network-side device.
[0437] Method 4: The amplitudes corresponding to each group of phase differences are reported separately.
[0438] The so-called group of phase differences refers to multiple phase differences corresponding to a time delay difference (such as one phase difference for each sub-band, and the phase differences of all sub-bands form a group of phase differences, or form a set of phase differences), or the phase differences corresponding to a measurement resource (combination).
[0439] First, determine the maximum value among the amplitudes corresponding to a group of phase differences (such as d max ), then divide all the amplitudes corresponding to this group of phase differences by d max and then perform Q-bit quantization. Optionally, the UE reports d max to the network-side device. Optionally, the UE also reports the sub-band index (or RB index or sub-carrier index) corresponding to d max , or the corresponding time delay difference index (such as the index value determined according to the reporting order of multiple time delay differences, and the time delay difference index of the i-th reported is i), or the corresponding measurement resource (combination) index to the network-side device.
[0440] Method 5: The amplitudes corresponding to all time delay differences are reported separately.
[0441] First, determine the maximum value among the amplitudes corresponding to all time delay differences (such as d max ), then divide all the amplitudes corresponding to the time delay difference by d max and then perform Q-bit quantization. Optionally, the UE reports the value of d max to the network-side device. Optionally, the UE also reports d maxThe corresponding sub-band index (or RB index or sub-carrier index) or the corresponding time delay difference index (such as the index value determined according to the reporting order of multiple time delay differences, and the time delay difference index of the i-th report is i), or the corresponding measurement resource (combination) index is reported to the network side device.
[0442] Method 6: The amplitudes corresponding to all phase differences are reported separately.
[0443] First, determine the maximum value among the amplitudes corresponding to all phase differences (such as d max ), and then divide all the amplitudes corresponding to the phase differences by d max and then perform Q-bit quantization. Optionally, the UE reports the value of d max to the network side device. Optionally, the UE also reports the sub-band index (or RB index or sub-carrier index) corresponding to d max or the corresponding time delay difference index (such as the index value determined according to the reporting order of multiple time delay differences, and the time delay difference index of the i-th report is i), or the corresponding measurement resource (combination) index to the network side device.
[0444] Method 7: All amplitudes are reported jointly.
[0445] First, determine the maximum value among all amplitudes (such as d max ), and then divide all amplitudes by d max and then perform Q-bit quantization. Optionally, the UE reports the value of d max to the network side device. Optionally, the UE also reports the sub-band index (or RB index or sub-carrier index) corresponding to d max or the corresponding time delay difference index (such as the index value determined according to the reporting order of multiple time delay differences, and the time delay difference index of the i-th report is i), or the corresponding measurement resource (combination) index to the network side device.
[0446] It should be noted that in this embodiment, the sub-band index (or RB index or sub-carrier index) corresponding to d max reported by the UE or the corresponding time delay difference index (such as the index value determined according to the reporting order of multiple time delay differences, and the time delay difference index of the i-th report is i), or the corresponding measurement resource (combination) index, etc. and the sub-band index or measurement resource (combination) index corresponding to the time delay difference or phase difference have different physical meanings, and it may be necessary to report the index corresponding to d max (such as the measurement resource (combination) index), and the index corresponding to the time delay difference or phase difference (such as the measurement resource (combination) index) in one report.
[0447] In a specific implementation, the UE reports first delay-related information and first phase-related information to the network-side device respectively. Here, when the first delay-related information is expressed as a delay difference and the first phase-related information is expressed as a phase difference: the UE reports the delay difference and the phase difference respectively. The UE does not need to determine the phase difference based on the delay difference, but independently determines the delay difference and the phase difference. After the UE reports them to the network-side device, the network-side device can perform joint processing or pre-compensation, etc. based on the delay difference and the phase difference reported by the UE.
[0448] The UE can report the delay difference by using the following differential method or report the delay difference by using a non-differential method:
[0449] Reporting the delay difference by the differential method: Suppose the UE measures and reports the measurement resources corresponding to 4 TRPs, and a total of 3 delay differences are measured. For example, the delay difference τ1 between measurement resource 2 and measurement resource 1, the delay difference τ2 between measurement resource 3 and measurement resource 1, and the delay difference τ3 between measurement resource 4 and measurement resource 1. Assume that τ2 is the smallest among the 3 delay differences, that is, τ2 = min(τ1, τ2, τ3). Then the UE can report τ2, (τ1 - τ2), and (τ3 - τ2). Among them, the reporting overhead of (τ1 - τ2) and the reporting overhead of (τ3 - τ2) will be lower than the reporting overhead of the non-differential delay differences (such as τ1, τ2, τ3), so as to reduce the feedback overhead.
[0450] For example, if the non-differential delay difference (such as τ2) is quantized using T1 bits, and the differential delay differences (such as (τ1 - τ2) and (τ3 - τ2)) are quantized using T2 bits, where T1 > T2.
[0451] Reporting the delay difference by the non-differential method: Still taking the reporting of 3 delay differences corresponding to 4 TRPs as an example, the UE reports them in ascending order or descending order of the delay difference, and each delay difference is quantized using T1 bits.
[0452] Optionally, the UE reports the measurement resource (combination) index corresponding to each delay difference (differential or non-differential delay difference).
[0453] In an alternative embodiment, the terminal sends first delay-related information corresponding to the multiple measurement objects to the network-side device, including:
[0454] The terminal determines reference delay-related information among the multiple first delay-related information;
[0455] The terminal determines the differences between the multiple first delay-related information and the reference delay-related information;
[0456] The terminal sends the differences and the reference delay-related information.
[0457] In an embodiment of the present application, reference delay-related information is determined based on multiple pieces of first delay-related information. The reference delay-related information is a reference object among the multiple pieces of first delay-related information. For example, the multiple pieces of first delay-related information include: TRP 1, TRP 2, TRP 3, and TRP 4. Any one of TRP 1, TRP 2, TRP 3, and TRP 4 can be used as the reference delay-related information. Further, the differences between the multiple pieces of first delay-related information and the reference delay-related information are calculated, and the terminal sends the differences and the reference delay-related information. Accordingly, the network-side device can determine the number of pieces of first delay-related information.
[0458] In a specific embodiment, when the terminal reports multiple pieces of first delay-related information and multiple pieces of first phase-related information, the first delay-related information is exemplified by a delay difference, and the first phase-related information is described by a phase difference distance. Among them, the multiple delay differences correspond to multiple measurement resources or measurement resource ports, and the multiple phase differences also correspond to multiple measurement resources or measurement resource ports.
[0459] For example, in a measurement report, the number of TRPs is 4, which are TRP 1, TRP 2, TRP 3, and TRP 4 respectively. Then the number of measurement resources or measurement resource ports is 4. Based on these measurement resources or measurement resource ports, the UE determines 3 delay differences, which respectively represent the delay differences between TRP 2-TRP 4 and TRP 1, that is, the delay difference between measurement resource 2 and measurement resource 1, the delay difference between measurement resource 3 and measurement resource 1, and the delay difference between measurement resource 4 and measurement resource 1. Another example is that the UE reports multiple groups of delay differences, such as taking measurement resource 1 as a reference, the delay differences between other measurement resources and measurement resource 1; taking measurement resource 2 as a reference, the delay differences between other measurement resources and measurement resource 2; taking measurement resource 3 as a reference, the delay differences between other measurement resources and measurement resource 3; taking measurement resource 4 as a reference, the delay differences between other measurement resources and measurement resource 4. In this case, the UE reports a total of 12 delay differences, which respectively represent:
[0460] The delay difference between measurement resource 2 and measurement resource 1, the delay difference between measurement resource 3 and measurement resource 1, and the delay difference between measurement resource 4 and measurement resource 1;
[0461] The delay difference between measurement resource 1 and measurement resource 2, the delay difference between measurement resource 3 and measurement resource 2, and the delay difference between measurement resource 4 and measurement resource 2;
[0462] The delay difference between measurement resource 1 and measurement resource 3, the delay difference between measurement resource 2 and measurement resource 3, and the delay difference between measurement resource 4 and measurement resource 3;
[0463] Measure the time delay differences between measurement resource 1 and measurement resource 4, between measurement resource 2 and measurement resource 4, and between measurement resource 3 and measurement resource 4.
[0464] Optionally, the terminal sends first time delay related information corresponding to the multiple measurement objects to the network side device, including:
[0465] The terminal reports the multiple pieces of first time delay related information in sequence based on a preset sorting strategy.
[0466] In the embodiments of this application, since multiple time delay differences are reported, it is necessary to determine the correspondence between the time delay differences and the measurement resources or measurement resource ports. The preset sorting strategy can be in ascending or descending order of the time delay differences. For example, the UE reports in ascending or descending order of the time delay differences and indicates the measurement resource (absolute or relative) index or measurement resource port (absolute or relative) index corresponding to the time delay difference. Because one time delay difference is associated with multiple measurement resources or multiple measurement resource ports, the measurement resource combination or measurement resource port combination corresponding to the time delay difference can also be determined by permutation and combination or a predefined method.
[0467] For example, a measurement resource set contains 4 measurement resources, and the permutation and combination of the 4 measurement resources is 4*3*2*1 = 24 kinds. Among them, (measurement resource 1, measurement resource 2, measurement resource 4, measurement resource 3) and (measurement resource 2, measurement resource 1, measurement resource 4, measurement resource 3) are different combination methods because they will affect the correspondence between the reported time delay difference and the measurement resource. In this case, the UE can use 5 bits to report which combination among the 24 combinations the time delay difference corresponds to; or, it can also be pre-specified that the combination method reported by the UE is a smaller set, such as the combinations when resources 1, 2, 3, and 4 are used as reference resources respectively, such as (measurement resource 1, measurement resource 2, measurement resource 3, measurement resource 4), (measurement resource 2, measurement resource 1, measurement resource 3, measurement resource 4), (measurement resource 3, measurement resource 1, measurement resource 2, measurement resource 4), (measurement resource 4, measurement resource 1, measurement resource 2, measurement resource 3). In this way, only 2 bits are needed to report the measurement resource combination corresponding to the time delay difference. The allowed measurement resource combinations can also be configured explicitly by the network side device.
[0468] Optionally, in this application, when there are 2 or more measurement resources, and each measurement resource corresponds to one or more pieces of first time delay related information or first phase related information, taking the measurement resource as the TRP, the first time delay related information as the time delay difference, and the first phase related information as the phase difference as an example, the steps of jointly reporting the time delay difference and the phase difference are further described.
[0469] For example, both the time delay difference and the phase difference are reported in one report, where the phase difference can be the residual phase difference after removing the influence of the time delay difference. Taking the reporting of the time delay difference and the phase difference corresponding to two TRPs in one feedback as an example, if the UE reports a time delay (difference) corresponding to two TRPs, denoted as τ, the phase (difference) corresponding to τ can have the following forms:
[0470] Form 1: 2πf j τ, with the unit of radian;
[0471] Form 2:
[0472] Form 3:
[0473] Among them, Form 3 is in the form of a vector. 1 indicates that the phase (difference) between TRP 1 and TRP 1 is 0, indicating that the phase (difference) between TRP 2 and TRP 1 is 2πf j τ. In fact, only Form 1 is the phase (difference). Using Forms 2 and 3 for feedback is to reduce the feedback overhead. For example, through the feedback of the precoding codewords in the precoding codebook (corresponding to Form 3), both the base station and the UE can determine the corresponding phase (difference) according to the precoding codewords.
[0474] If the UE measures the phase difference between two TRPs in the frequency domain, such as or It is also possible to further subtract the influence of the phase difference corresponding to the time delay on this basis (such as 2πf j τ, or ), so as to further reduce the feedback overhead by reducing the value of the phase difference.
[0475] In this application, in the case of reporting one time delay difference and multiple phase differences, among them, the time delay difference is the time delay difference between two TRPs or two measurement resources, and the phase difference is the phase difference of each subband or PRB or PRB group in the frequency domain.
[0476] In this embodiment, the subband granularity of the phase difference reporting is B PRBs, where B is reported by the UE to the network device. It should be noted that the subband granularity of the phase difference reporting and the PMI reporting granularity defined in the 5G NR protocol can be the same or different. The subband granularity needs to match the change of the phase difference to ensure that the phase difference reported within one subband is applicable to the entire subband. In this application, the UE measures the phase difference and reports the reporting granularity of the phase difference. The subband granularity (also called the first subband granularity) of the reported phase difference can be 0.5 PRB, 1 PRB, 2 PRB, 3 PRB, 4 PRB,..., 32 PRB,..., 64 PRB, etc.
[0477] When the time delay difference is τ, the reported phase difference is the measured phase difference minus mod(2πf0τ, 2π) (such as the value obtained by quantifying the phase difference form one according to the first quantization method; or the phase difference is the measured value divided by (such as phase difference form two or form three), and then the value obtained by quantifying according to the second quantization method or quantization codebook. Since the measured phase (difference) is usually between [0, 2π], when calculating the differential phase difference, 2πf j The value of τ needs to be converted to the range of [0, 2π], while and the corresponding measured phase (difference) have no requirements on the phase and do not need to convert the phase to the range of [0, 2π].
[0478] Optionally, in the case of reporting multiple time delay differences and multiple phase differences in this application, among them, when the terminal reports resources to the network side device, each time delay difference corresponds to one or more phase differences. The reporting format for the UE to report resources to the network side device can be as shown in Table 9 below:
[0479] Table 9:
[0480]
[0481] The reporting format for the UE to report resources to the network side device can also be as shown in Table 10 below, where T represents the number of time delay differences.
[0482] Table 10:
[0483]
[0484]
[0485] In this application, the reported phase difference is the value obtained by subtracting the phase value corresponding to the corresponding time delay difference from the measured phase difference and then quantifying according to the first quantization method, or the phase difference is the value obtained by dividing the measured value by the frequency domain value corresponding to the corresponding time delay difference (equivalent to having a value in the exponential domain) and then quantifying according to the second quantization method or quantization codebook.
[0486] Optionally, the method of the embodiment of this application further includes:
[0487] When sending the first phase-related information to the network side device, the terminal sends information on the phase range used for quantization;
[0488] When sending the first time delay-related information to the network side device, the terminal sends information on the time range used for quantization.
[0489] In the embodiments of the present application, when the network-side device calculates the quantization codebook, whether it is the above-mentioned first quantization method or the second quantization method, it is necessary to use the information of the quantization corresponding phase range or the information of the time range used for quantization. When sending the first phase-related information or the first delay-related information, sending the phase range and the time range is beneficial to reducing the time of subsequent quantization processing.
[0490] Optionally, the phase range or the time range includes at least one of the following:
[0491] [0, a];
[0492] [a, b];
[0493] [-a, 0];
[0494] [-a, b];
[0495] Range number w, and the range corresponding to w is pre-specified in the protocol;
[0496] wherein, a and b are positive numbers;
[0497] When the terminal reports the information of the phase range or the time range used for quantization, it includes:
[0498] The terminal sends at least one of a, b, and w.
[0499] In the embodiments of the present application, when the terminal sends at least one of a, b, and w, it can make the UE feedback the reporting range of the frequency-domain phase difference, such as the range is [a, b], [-a, b] or [0, b], and the unit is radians or degrees. Among them, a or b is a positive value, and the value is configured by the network-side device, or pre-specified in the protocol, or reported by the UE to the network side. After determining the reporting range, the UE reports according to the quantization granularity corresponding to the reporting range. Or, the phase difference is quantized in a uniform quantization manner, such as both the reporting range and the reporting granularity are pre-specified in the protocol. The purpose of setting the above phase range or time range can achieve a higher-precision reporting with less signaling overhead.
[0500] In summary, the measurement reporting method on the terminal side in the embodiments of the present application is used to report at least two of the time delay difference, phase difference, and amplitude between multiple measurement objects. Through this method, the time difference, phase difference, or reciprocity error between multiple measurement objects can be accurately eliminated.
[0501] Referring to Figure 2 as shown, the embodiments of the present application further provide a measurement reporting method, including:
[0502] Step 21, the terminal determines multiple measurement objects.
[0503] In this application, the measurement object can be a measurement resource or a measurement resource port, etc. By way of example, 1 measurement resource includes multiple measurement resource ports. The multiple measurement objects can be the multiple measurement resource ports of 1 measurement resource. Or, the multiple measurement objects can be multiple measurement resources or the multiple resource ports respectively corresponding to multiple measurement resources. Or, the multiple measurement objects can be multiple measurement resource sets. For another example, 1 measurement resource port corresponds to 1 TRP, and the multiple measurement objects can be represented as multiple TRPs. This application places no restrictions thereon.
[0504] Step 22: The terminal sends first delay-related information or first phase-related information corresponding to the multiple measurement objects to the network-side device.
[0505] Step 23: When sending the first phase-related information to the network-side device, the terminal sends information on the phase range used for quantization.
[0506] Step 24: When sending the first delay-related information to the network-side device, the terminal sends information on the time range used for quantization.
[0507] In the embodiments of this application, different from the above terminal-side implementation method, in step 22, the terminal sends first delay-related information or first phase-related information to the network-side device. Based on the first delay-related information or first phase-related information, it is beneficial to reduce the feedback overhead. Since when the network-side device calculates the quantization codebook, whether it is the above first quantization method or the second quantization method, it is necessary to use the information on the phase range corresponding to quantization or the information on the time range used for quantization. When sending the first phase-related information or first delay-related information, sending the phase range and time range is beneficial to reducing the time for subsequent quantization processing.
[0508] Optionally, the phase range or the time range includes at least one of the following:
[0509] [0, a];
[0510] [a, b];
[0511] [-a, 0];
[0512] [-a, b];
[0513] Range number w, and the range corresponding to w is predefined in the protocol;
[0514] wherein, a and b are positive numbers;
[0515] The terminal reports and sends the information on the phase range used for quantization or the information on the time range, including:
[0516] The terminal sends at least one of a, b, and w.
[0517] Optionally, the quantization granularity or the number of quantization values is different in different phase ranges or different time ranges, and the quantization granularity value or the number of quantization values corresponding to the phase range or the time range is pre-specified by the protocol.
[0518] In an embodiment of the present application, when the terminal sends at least one of a, b, and w, the UE can be made to feedback the reporting range of the frequency domain phase difference, such as the range being [a, b], [-a, b], or [0, b], with the unit being radians or degrees. Among them, a or b is a positive value, and the value is configured by the network-side device, pre-specified in the protocol, or reported by the UE to the network side. After determining the reporting range, the UE reports according to the quantization granularity corresponding to the reporting range. Alternatively, the phase difference is quantized in a uniform quantization manner, such as both the reporting range and the reporting granularity being pre-specified by the protocol. The purpose of setting the above phase range or time range is to achieve a higher-precision reporting with less signaling overhead.
[0519] Optionally, the first phase-related information is determined according to at least one of the following codebooks:
[0520] The first codebook W1,
[0521] The second codebook W2, Among them, the value of P is configured by a high-layer parameter, and P is less than or equal to N;
[0522] The third codebook W3,

[0524] The fifth codebook W5, Among them, the value of P is configured by a high-layer parameter, and P is less than or equal to N;
[0525] The sixth codebook W6, Among them, P q The value of is configured by a high-layer parameter, and q = 1, 2,..., K - 1;
[0526] Among them, N is a positive integer, and K is determined by the number of measurement objects.
[0527] In the embodiments of the present application, when the number of measurement objects (such as the number of TRPs, the number of measurement resources, or the number of measurement resource ports) is 2, the quantization codebook can be represented in the form of a first codebook, where i in the first codebook represents the precoding codeword index. In this embodiment, the number of network layers corresponding to the precoding codeword can be limited to 1, such as for the network side to recover the downlink channel information according to the precoding codeword.
[0528] In one implementation, the phase differences reported by the UE are after differential operations, so only some of the precoding codewords can be reported. One method is to configure a subset restriction for UE measurement reporting, such as using N bits to configure which precoding codewords the UE can report through bit mapping; for another example, let i take values of 0, 1, 2, …, P - 1, where the value of P is configured by a higher layer parameter.
[0529] Another method is to report in the form of the above-mentioned second codebook. Among them, the value of P in the above-mentioned second codebook is configured by a higher layer parameter. When the number of measurement objects (such as the number of TRPs, the number of measurement resources, or the number of measurement resource ports) is 2, the quantization codebook used can be represented in the form of the above-mentioned third codebook or the above-mentioned fourth codebook. Among them, in the third codebook, the quantization method for each phase difference is the same, that is, the phase value distributions corresponding to the phase differences are the same; in the fourth codebook, the phase value distributions corresponding to each phase difference can be different.
[0530] Similarly, the phase difference can also be reported by codebook subset restriction or by a new codebook to reduce the feedback overhead, and the form of the quantization codebook can be represented in the form of the above-mentioned fifth codebook or the above-mentioned sixth codebook. Among them, the value of P in the fifth codebook, or the value of P k (k = 1, 2, …, K - 1) is configured by a higher layer parameter.
[0531] Optionally, the terminal sends first phase-related information corresponding to the multiple measurement objects to the network-side device, including:
[0532] The terminal jointly reports the first phase-related information related to the same delay-related information; or,
[0533] The terminal jointly reports the first phase-related information corresponding to the measurement resources of the same measurement object; or,
[0534] The terminal jointly reports the multiple first phase-related information corresponding to the same subband; or,
[0535] The terminal jointly reports the first phase-related information of the same type; or,
[0536] The terminal jointly reports all the determined first phase-related information.
[0537] In the embodiments of the present application, the reporting form of jointly reporting the first phase-related information corresponding to multiple measurement objects to the network-side device includes at least one of the following:
[0538] (1) The terminal jointly reports the first phase-related information related to the same first time-delay related information. For example, the terminal can jointly report the phase differences corresponding to each determined time-delay difference.
[0539] (2) The terminal jointly reports the first phase-related information corresponding to the same measurement object. For example, the terminal can jointly report the phase differences corresponding to the same measurement resource (or a measurement resource combination formed by combining multiple measurement resources).
[0540] (3) The terminal jointly reports the first phase-related information corresponding to the multiple reported first time-delay related information. For example, the phase differences corresponding to the multiple time-delay differences reported by the UE can be jointly reported.
[0541] (4) The terminal jointly reports the multiple first phase-related information corresponding to the same sub-band. For example, the terminal jointly reports the phase differences corresponding to the same sub-band.
[0542] (5) The terminal jointly reports the first phase-related information of the same type. For example, the first phase-related information of the same type, such as type one, can be jointly reported. In the present application, the phase differences between different types can also be jointly reported, such as the phase differences between type two and type three, and type two and type three are different.
[0543] (6) The terminal jointly reports all the determined first phase-related information. For example, the terminal jointly reports all the phase differences.
[0544] It should be noted that Figure 1 The embodiments in the measurement reporting method on the terminal side corresponding thereto can also be applied to the method of the present application, which will not be elaborated here.
[0545] In summary, the measurement reporting method on the terminal side in the embodiments of the present application is used to report the time-delay difference or phase difference between multiple measurement objects. Through this method, the amount of data calculation can be reduced, and the overhead on the terminal side can be reduced.
[0546] Referring to Figure 3 As shown, the embodiments of the present application further provide a measurement acquisition method, including:
[0547] Step 31, the network device receives first delay-related information and first phase-related information corresponding to multiple measurement objects sent by the terminal; wherein, the first delay-related information is related to the first phase-related information.
[0548] In this application, the network device may configure multiple measurement resources for the UE. The measurement resources may be CSI-RS resources, or may be SSB resources, TRS resources, etc. The multiple measurement resources may be configured in a measurement resource set (such as a CSI-RS resource set), or may be configured in multiple measurement resource sets. This application does not limit this. One measurement resource, or multiple measurement resources in a measurement resource set, corresponds to one TRP.
[0549] In the embodiments of this application, the network device receives first delay-related information corresponding to multiple measurement objects sent by the terminal, and sends first phase-related information related to the first delay-related information. The first delay-related information may be the measured measurement delay, or may be the delay obtained by measurement and then processing. The first phase-related information may be calculated from the measured phase and the corresponding measurement delay. By simultaneously receiving the correlated delay and phase, the network device performs preprocessing to pre-eliminate the delay difference or phase difference between multiple measurement objects, reducing the feedback overhead.
[0550] Optionally, in the embodiments of this application, the first delay-related information and the first phase-related information may be independent of each other. For example, the first delay-related information and the first phase-related information may be measured separately, or may be measured separately and then processed and reported. Alternatively, the first delay-related information and the first phase-related information are reported in one report, but the first delay-related information and the first phase-related information are independently quantized. It should be noted that although the two may be independently reported, there is a correlation between the two, that is, the first delay-related information is related to the first phase-related information. Exemplarily, the first delay-related information and the first phase-related information are reported separately: the first delay-related information (delay difference) is reported using a differential or non-differential method.
[0551] Optionally, the network device receives the amplitude corresponding to the multiple measurement objects sent by the terminal.
[0552] In an embodiment of the present application, while receiving first delay-related information and first phase-related information, the amplitudes corresponding to multiple measurement objects are received, where the amplitudes may be the amplitudes corresponding to multiple first delay-related information or the amplitudes corresponding to multiple first phase-related information. The present application simultaneously receives at least one of the first delay-related information, the first phase-related information, the amplitude corresponding to the first delay-related information, and the amplitude corresponding to the first phase-related information. By this method, the time difference, phase difference, reciprocity error, etc. between multiple TRPs can be accurately eliminated.
[0553] Optionally, when the network-side device receives the measurement report from the terminal, it can receive at least two of the first delay-related information, the first phase-related information, and the amplitude between multiple measurement objects. For example, the present application can receive the first delay-related information and the first phase-related information for joint reporting information; it can also receive the measurement report information of the first delay-related information and the amplitude separately, etc.
[0554] Optionally, the first phase-related information is determined based on a quantization codebook;
[0555] The quantization codebook includes at least one of the following:
[0556] The first codebook W1,
[0557] The second codebook W2, where the value of P is configured by a higher-layer parameter, and P is less than or equal to N;
[0558] The third codebook W3,
[0559] The fourth codebook W4, where N p The value of is configured by a higher-layer parameter or predefined in the protocol, and p = 1, 2,..., K - 1;
[0560] The fifth codebook W5, where the value of P is configured by a higher-layer parameter, and P is less than or equal to N;
[0561] The sixth codebook W6, where P q The value of is configured by a higher-layer parameter, and q = 1, 2,..., K - 1;
[0562] where N is a positive integer, and K is determined by the number of measurement objects.
[0563] In the embodiments of the present application, when the number of measurement objects (such as the number of TRPs, the number of measurement resources, or the number of measurement resource ports) is 2, the quantization codebook can be represented in the form of a first codebook, where i in the first codebook represents the precoding codeword index. In this embodiment, the number of network layers corresponding to the precoding codeword can be limited to 1, such as for the network side to recover the downlink channel information according to the precoding codeword.
[0564] In one implementation, the phase differences reported by the UE are subject to differential operations, so only some of the precoding codewords can be reported. One method is to configure a subset limit for the UE's measurement report. For example, use N bits to configure which precoding codewords the UE can report through bit mapping; another example is to let i take values of 0, 1, 2, …, P - 1, where the value of P is configured by a high-layer parameter. Another method is to report in the form of the above-mentioned second codebook. Among them, the value of P in the above-mentioned second codebook is configured by a high-layer parameter. When the number of measurement objects (such as the number of TRPs, the number of measurement resources, or the number of measurement resource ports) is 2, the quantization codebook used can be represented in the form of the above-mentioned third codebook or the above-mentioned fourth codebook. Among them, in the third codebook, the quantization method for each phase difference is the same, that is, the phase value distributions corresponding to the phase differences are the same; in the fourth codebook, the phase value distributions corresponding to each phase difference can be different.
[0565] Similarly, phase difference reporting can also be performed through codebook subset restriction or through a new codebook to reduce the feedback overhead. The form of the quantization codebook can be represented in the form of the above-mentioned fifth codebook or the above-mentioned sixth codebook. Among them, the value of P in the fifth codebook, or P k (k = 1, 2, …, K - 1) in the sixth codebook is configured by a high-layer parameter.

One method is to configure a subset limit for UE measurement reporting, such as using N bits to configure which precoding codewords the UE can report through bit mapping; for another example, let i take values of 0, 1, 2, …, P - 1, where the value of P is configured by high-layer parameters. Another method is to report in the form of the above-mentioned second codebook. Among them, the value of P in the above-mentioned second codebook is configured by high-layer parameters. When the number of measurement objects (such as the number of TRPs or the number of measurement resources or the number of measurement resource ports) is 2, the quantization codebook used can be represented in the form of the above-mentioned third codebook or the above-mentioned fourth codebook. Among them, in the third codebook, the quantization method for each phase difference is the same, that is, the phase value distributions corresponding to the phase differences are the same; in the fourth codebook, the phase value distributions corresponding to each phase difference can be different.
[0629] Similarly, the phase difference can also be reported through codebook subset restriction or through a new codebook to reduce the feedback overhead, and the form of the quantization codebook can be represented in the form of the above-mentioned fifth codebook or the above-mentioned sixth codebook. Among them, the value of P in the fifth codebook, or P k (k = 1, 2, …, K - 1) in the sixth codebook is configured by high-layer parameters.
[0630] It should be noted that Figure 1 and Figure 2 The embodiments in the measurement reporting method on the terminal side corresponding to it can also be applied to the method of the present application, which will not be elaborated here.
