[0214] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0215] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0216] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0217] To enable those skilled in the art to better understand the embodiments of the present disclosure, the following description is first given:

[0218] 1. CJT Transmission

[0219] CJT technology supports coherent transmission of up to 4 TRPs. Assume that the channels of the 4 TRPs and the user equipment (UE) are H i , the signal y received by the UE can be expressed as:

[0220] y=[H1 H2 H3 H4]Wx+n

[0221] Where W is the precoding codeword for the joint transmission of the four TRPs, x is the signal sent by each TRP, and n is the receiver noise. As can be seen from the above formula, in CJT transmission, the precoding codewords of all TRPs can be expressed as a joint matrix, that is, the precoding codeword is jointly determined based on the channel conditions of all TRPs.

[0222] 2. Measurement and reporting technology:

[0223] 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 includes one or more CSI reference signal (CSI-RS) resources. The UE reports according to the reporting amount configured by the network side. For example, the reporting amount configured by the network side is as follows:

[0224] Among them, CSI or synchronization signal block index (ssb-Index) refers to the index of CSI-RS resource or synchronization signal block (Synchronization Signal Block, SSB) resource, which indicates the subsequent reporting amount measured by the UE according to the measurement resource index corresponding to the CSI-RS resource or SSB resource, such as rank indication (Rank Indication, RI), precoding matrix indication (Precoding Matrix Indicator, PMI), channel quality indication (Channel Quality Indicator CQI), etc.

[0225] The embodiments of the present disclosure provide a measurement reporting method, a measurement acquisition method, an apparatus, and a readable storage medium. The method and apparatus are based on the same patent application concept. Since the method and apparatus solve similar problems, the implementation of the apparatus and method can refer to each other, and the repetitive parts will not be repeated.

[0226] As shown in FIG1 , a measurement reporting method provided in an embodiment of the present disclosure includes:

[0227] Step 11: The terminal determines multiple measurement objects;

[0228] In the present disclosure, the measurement object may be a measurement resource, a measurement resource port, or the like. For example, one measurement resource includes multiple measurement resource ports, and the multiple measurement objects may be multiple measurement resource ports of the one measurement resource. Alternatively, the multiple measurement objects may be multiple measurement resources or multiple resource ports corresponding to multiple measurement resources, or the multiple measurement objects may be multiple measurement resource sets. For another example, one measurement resource port corresponds to one TRP, and multiple measurement objects may be represented as multiple TRPs, which is not limited in the present disclosure.

[0229] For example, the measurement object is a measurement resource. The network side configures multiple measurement resources for the UE. The measurement resources can be CSI-RS resources, SSB resources, CSI-RS for Tracking (TRS) resources for tracking, etc. Multiple measurement resources can be configured in one measurement resource set (such as CSI-RS resource set) or in multiple measurement resource sets. This disclosure does not limit this. One measurement resource, or multiple measurement resources in a measurement resource set, corresponds to one TRP.

[0230] In step 12, the terminal sends first delay-related information and first phase-related information corresponding to the multiple measurement objects to a network-side device; wherein the first delay-related information is related to the first phase-related information.

[0231] Here, the first delay-related information includes delay or delay difference, and the first phase-related information includes phase or phase difference.

[0232] It should be noted that when measuring reciprocity error, the phase difference is equivalent to the phase difference between the frequency domain channel impulse responses of two TRPs. When measuring time error, the phase difference is the phase difference between the channel impulse responses of another TRP in different frequency domains when receiving according to the timing of one TRP. In fact, it is also equivalent to the delay difference between the two TRPs.

[0233] In an embodiment of the present disclosure, a terminal sends first delay-related information corresponding to multiple measurement objects to a network-side device, as well as first phase-related information related to the first delay-related information. The first delay-related information may be a measured delay or a delay obtained by first measuring and then processing. The first phase-related information may be calculated from the measured phase and the corresponding measured delay. By simultaneously sending correlated delays and phases, the present disclosure pre-eliminates delay or phase differences between multiple measurement objects through pre-processing by the network-side device, thereby reducing feedback overhead.

[0234] In some embodiments, the multiple measurement objects are configured by the network side for the UE, and the specific configuration is implemented by one or more measurement resource sets:

[0235] 1. Configure P1 measurement resource sets, each measurement resource set contains at least one measurement resource, and the UE performs measurement and reporting based on at least one measurement resource in each measurement resource set among at least two measurement resource sets;

[0236] 2. Configure a measurement resource set containing multiple measurement resources, and the UE performs (measurement and reporting) based on at least two measurement resources;

[0237] 3. Configure one measurement resource set, including one measurement resource, and the UE performs (delay difference, frequency difference, phase difference) measurement and reporting based on at least two antenna ports of the measurement resource.

[0238] In some embodiments of the present disclosure, the terminal may further send mutually independent first delay-related information and first phase-related information to the network-side device. 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 may be reported in one report, but the first delay-related information and the first phase-related information may be quantized independently.

[0239] An embodiment of the present disclosure provides a method for measuring delay difference: the UE detects measurement resources (such as SSB resources) sent by two TRPs, and determines the timing of each TRP based on the position distance of the detected autocorrelation peaks. For example, the first detected peak corresponds to the receiving time of the first TRP, and the second detected peak corresponds to the receiving time of the second TRP. If the sending time of the two TRP measurement resources differs by T1 and the receiving peaks differ by T2, then the delay difference between the two TRPs is T2-T1.

[0240] An embodiment of the present disclosure 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, the UE calculates the phase difference of the frequency domain channel impulse response of the channel on the same resource block (RB) (group) based on a reference antenna of TRP 2 and a channel between a reference antenna of the UE. The phase difference corresponds to the time difference between TRP 2 and TRP 1.

[0241] In some embodiments, when the UE of the present disclosure performs measurement reporting, the UE's reporting format may be:

[0242] First report the first delay related information, and then report the first phase related information; or,

[0243] When multiple measurement resources are divided into multiple measurement resource combinations, the first delay-related information and the first phase-related information corresponding to one measurement resource (combination) may be reported first, and then the first delay-related information and the first phase-related information corresponding to other measurement resources (combinations) may be reported.

[0244] In an optional embodiment, the method of the present disclosure further includes:

[0245] The terminal sends the amplitudes corresponding to the multiple measurement objects to the network side device.

[0246] In an embodiment of the present disclosure, when a terminal performs measurement reporting to a network-side device, it may report amplitudes corresponding to multiple measurement objects simultaneously with reporting first delay-related information and first phase-related information. The present disclosure simultaneously 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. This method accurately eliminates time differences, phase differences, or reciprocity errors between multiple TRPs.

[0247] For example, when the first delay-related information includes the delay difference and the first phase-related information includes the phase difference, when the UE reports the delay difference, the phase difference, and the amplitude, the reporting format of the UE may be:

[0248] First report the delay difference, phase difference, and then the amplitude (the order of phase difference and amplitude can be reversed); or,

[0249] Report the delay difference, phase difference and amplitude corresponding to one measurement resource (combination), and then report the delay difference, phase difference and amplitude corresponding to other measurement resource combinations.

[0250] In some embodiments, when a terminal performs measurement reporting to a network-side device, it may report at least two items of first delay-related information, first phase-related information, and amplitude values ​​between multiple measurement objects. For example, the present disclosure may report first delay-related information and first phase-related information; it may also measure and report first delay-related information and amplitude values.

[0251] In an optional embodiment, the method of the present disclosure further includes:

[0252] Determining, by the terminal, one or more pieces of second phase-related information of the multiple measurement objects and second delay-related information corresponding to the second phase-related information;

[0253] 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;

[0254] The terminal obtains the first phase-related information by quantizing the third phase-related information.

[0255] In an embodiment of the present disclosure, the first phase-related information is the phase (or phase difference) after removing the influence of the delay (or delay difference). In the present disclosure, after the terminal determines one or more second phase-related information, it can determine the second delay-related information corresponding to the second phase-related information, and the one or more second phase-related information can correspond to a second delay-related information. The present disclosure performs delay removal processing on the second phase-related information based on the second delay-related information to obtain third phase-related information, which is conducive to eliminating possible errors and interference and improving the reliability and accuracy of the measurement results; the terminal obtains first phase-related information that is correlated with the first delay-related information by quantizing the third phase-related information, and reporting the quantized first phase-related information can reduce transmission consumption.

[0256] In some embodiments, 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, including:

[0257] The terminal subtracts the first value from the second phase related information to obtain the third phase related information;

[0258] The first value is calculated by the formula mod(2πf0τ,2π); τ is the second delay related information; f0 is the configured frequency value, or the center frequency value corresponding to a specific transmission resource, or a frequency value determined by at least one of the following: the center frequency value corresponding to the first transmission resource, the subcarrier spacing, the resource granularity, and the subcarrier format contained in each resource block.

[0259] Here, transmission resources refer to multiple resources obtained by dividing available resources according to preset rules. These transmission resources can be understood as subbands. For example, if the available resources include 200 PRBs, and they are divided into groups of 8 PRBs, 25 subbands can be obtained. Alternatively, if the available resources include 200 PRBs, and they are divided into groups of 2 PRBs, 100 subbands can be obtained. The subband granularity for reporting delay-related information and phase-related information can be slightly smaller than the subband granularity for other CSI reports.

[0260] In some embodiments, the UE reports the sub-band granularity so that the network device can perform subsequent processing after receiving the first phase related information.

[0261] Taking the transmission resource as a subband, f0 in this disclosure may include any of the following forms:

[0262] Option 1: f0 is the frequency value configured by the higher-level parameters.

[0263] Option 2: f0 is the center frequency value corresponding to the jth subband, which is determined by the higher-layer parameters "absoluteFrequencyPointA" and "offsetToPointA" and a predefined formula (including subcarrier spacing or subband spacing, etc.). For example, the center frequency value of the first subband is the value configured by absoluteFrequencyPointA + the value configured by offsetToPointA + C, where the value C is the offset between the measurement resource and the center frequency of the SIB transmission, and the value C is configured by higher-layer signaling.

[0264] Option 3: f0 is the center frequency value corresponding to the first subband, that is, f1. All subbands determine the phase (difference) based on the same center frequency. The method for determining f1 is the same as Option 1 and Option 2.

[0265] Option 4: f0, the center frequency of the first subband, is directly configured by high-level parameters, and the center frequencies of other subbands are determined by formulas, such as the center frequency of the jth (j>1) subband Where f1 is the center frequency of the first subband, SCS is the subcarrier spacing, such as 15kHz, 30kHz, etc., G is the granularity of the subband, the unit is transport block RB or physical transport block PRB, such as a subband contains 0.5 RB, etc. The number of subcarriers contained in an RB.

[0266] For example, at least f1, the center frequency of the first subband, is directly configured by high-level parameters, and the center frequencies of other subbands are determined by formulas such as

[0267] In the disclosed embodiment, the second phase-related information is mod(2πf0τ,2π) to obtain a first value, and then the terminal subtracts the first value from the second phase-related information to obtain a third phase-related information, which can ensure that the phase (difference) is small. Based on this, a more sophisticated codebook is designed to ensure accurate reporting of the phase (difference).

[0268] It is important to note that phase-related information can be in various forms, including: j τ, in radians; Form 2: Form 3: The above-mentioned method for determining the third phase-related information is applicable to the case where the second phase-related information is in form one. When the second phase-related information is in form two, 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 the first value f0. When the second phase related information is in form three, the terminal can be based on The third phase related information is obtained by performing a dot division on the second phase related information element, where τ is the second time delay related information and f0 is the same as the first value f0.

[0269] In some embodiments, the terminal obtains the first phase-related information by quantizing the third phase-related information, including:

[0270] The terminal quantizes the third phase-related information using a quantization codebook to determine the first phase-related information.

[0271] In the embodiments of the present disclosure, the quantization codebook may be a configured or preconfigured codebook, and the transmission type of the quantization codebook may be a coherent transmission codebook or a non-coherent transmission codebook, which is not limited in the present disclosure. The present disclosure quantizes the third phase-related information using the quantization codebook, or quantizes the third phase-related information using the first quantization method to determine the first phase-related information.

[0272] For example, when the third phase-related information represents the phase (difference) in the following form, taking the first delay-related information such as the delay difference and the first phase-related information such as the phase difference corresponding to two TRPs as an example, if the UE feeds back a delay (difference) corresponding to two TRPs, counted as τ, the phase (difference) corresponding to τ can have the following forms:

[0273] Form 1: 2πf j τ, in radians;

[0274] Form 2:

[0275] Form 3:

[0276] Among them, form three is a vector form, 1 means that the phase (difference) between TRP 1 and TRP 1 is 0, Indicates that the phase (difference) between TRP 2 and TRP 1 is 2πf j In essence, only form 1 is the phase (difference). Forms 2 and 3 are used to reduce feedback overhead. For example, by feeding back the precoded codeword in the precoding codebook (corresponding to form 3), both the base station and the UE can determine the corresponding phase (difference) based on the precoded codeword.

[0277] The first quantification method mentioned above: Since the delay difference and the phase difference are corresponding, the delay difference or phase difference between the two TRPs is reflected from different dimensions. Therefore, the phase difference value obtained by subtracting the frequency domain phase corresponding to the measured delay difference from the measured frequency domain phase difference (such as the corresponding One method is to let the UE feedback the phase range used for quantization of the frequency domain phase difference, also known as the reporting range, such as the range of [a, b], [-a, b] or [0, b], and the unit is radians or degrees. The value a or b is a positive value, and the value is 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 quantizes the third phase related information according to the quantization granularity corresponding to the phase range, and reports the first phase related information after obtaining it. Another approach is to quantize the third phase related information using uniform quantization, such as if the reporting range and quantization granularity are both pre-specified by the protocol.

[0278] In some embodiments, the third phase related information is expressed in the form of When representing the phase (difference), the present disclosure may further quantize the third phase-related information through a quantization codebook or a second quantization method to determine the first phase-related information.

[0279] Second quantization method: Similar to the first quantization method, when the phase (difference) is in the form of When the UE can calculate the phase difference of the index domain (such as the corresponding The value of or In this case, the phase range used can be [c, d] or [0, d], where c or d are positive values. These values ​​are configured by the network device, pre-defined in the protocol, or reported by the UE to the network device. After determining the reporting range, the UE reports according to the quantization granularity corresponding to the reporting range. Alternatively, both the reporting range and quantization granularity are pre-defined by the protocol.

[0280] In a specific implementation provided by the present disclosure, the first phase-related information is determined as follows:

[0281] The terminal reports a first delay-related information such as a 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, the reported first phase-related information such as the phase (difference) is the second phase-related information, that is, the measured phase (difference). After subtracting the first value (the second phase-related information mod (2πf0τ, 2π)) to determine the third phase-related information, it is determined according to the value quantized by the first quantization method; or the first phase-related information such as the phase (difference) is the second phase-related information, that is, the measured value (equivalent to the value in the exponential domain) divided by Then, the value is quantized according to the first codebook.

[0282] In another specific implementation provided by the present disclosure, the third phase related information is determined as follows:

[0283] The terminal reports the first delay-related information such as multiple delays (differences) (corresponding to multiple TRPs or measurement resources), and the reported second phase-related information such as phase (difference) is the second phase-related information such as the measured phase (difference) minus the corresponding second delay-related information such as the phase value corresponding to the delay (difference) (such as the second phase-related information mod (2πf j τ,2π)), and then quantized according to the first quantization method; or the first phase-related information such as the phase (difference) is the second phase-related information, that is, the measured value is divided by the corresponding second delay-related information such as the frequency domain value corresponding to the delay (difference) (equivalent to the value in the exponential domain), and then quantized according to the quantization codebook or the second quantization method.

[0284] Furthermore, in an optional embodiment of the present disclosure, the quantization codebook includes at least one of the following:

[0285] A first codebook, wherein the first codebook includes N-1 W1s, and each of the N-1 W1s is different.

[0286] A second codebook, wherein the second codebook includes P-1 W2, and each W2 in the P-1 W2 is different, The value of P is configured by high-level parameters and is less than or equal to N.

[0287] A third codebook, wherein the third codebook includes N-1 W3, and each W3 in the N-1 W3 is different,

[0288] A fourth codebook, wherein the fourth codebook includes N1-1 W4s, and each of the N1-1 W4s is different. Among them, N p The value of is predefined by the high-level parameter configuration or protocol, p = 1, 2, ..., K-1;

[0289] A fifth codebook, wherein the fifth codebook includes P-1 W5s, and each of the P-1 W5s is different. The value of P is configured by high-level parameters and is less than or equal to N.

[0290] A sixth codebook, wherein the sixth codebook includes P1-1 W6, and each W6 in the P1-1 W6 is different, Among them, P q The value of is configured by high-level parameters, q = 1, 2, ..., K-1;

[0291] Where N is a positive integer and K is determined by the number of measurement objects.

[0292] It should be noted that, in the embodiment of the present disclosure, when the third phase-related information is quantized using a quantization codebook, the terminal will feedback a 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) based on the precoding codeword. The quantization codebook can also be understood as a precoding codebook.

[0293] In the embodiment of the present disclosure, 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 by a first codebook, where i in the first codebook represents a precoding codeword index. For example, when the precoding codebook contains 2 bits, the corresponding precoding codeword set can be represented by the following Table 1:

[0294] Table 1:

[0295] Among them, Codebook index represents the codebook index; Number of layers represents the number of network layers corresponding to the precoding codeword.

[0296] Furthermore, when the precoding codebook contains 3 bits, the corresponding precoding codeword set is, which can be represented by the following Table 2:

[0297] Table 2:

[0298] In this embodiment, the number of network layers corresponding to the precoding codeword may be limited to 1, for example, for the network side to recover downlink channel information based on the precoding codeword.

[0299] In one implementation, the phase difference reported by the UE undergoes a differential operation, so only some precoding codewords may be reported. One method is to configure a subset restriction for measurement reporting for the UE, such as using N bits to configure which precoding codewords the UE can report through bit mapping; for example, let i take the value of 0, 1, 2, …, P-1, where the value of P is configured by a high-level parameter.

[0300] Another method is to report using the second codebook, wherein the value of P in the second codebook is configured by a high-level parameter.

[0301] 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 expressed in the form of the third codebook mentioned above or the fourth codebook mentioned above.

[0302] In the third codebook, the quantization method of 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 may be different.

[0303] Similarly, the phase difference may be reported by limiting the codebook subset or using a new codebook to reduce feedback overhead. The quantization codebook may be in the form of the fifth codebook or the sixth codebook.

[0304] Among them, the value of P in the fifth codebook, or P in the sixth codebook k The value of (k=1, 2, ..., K-1) is configured by high-level parameters.

[0305] For example, when measuring the reciprocity error, we still take two TRPs as an example. Each TRP selects a reference antenna and the UE selects a reference antenna. The UE first measures the frequency domain channel impulse response of the equivalent channel composed of the UE reference antenna and the TRP reference antenna. Assuming that H = [h1 h2], the UE multiplies H according to the first codebook and selects the optimal precoding matrix in the codebook according to the maximum two-norm principle. For example, the optimal precoding matrix is This means the phase difference between the two 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 based on the third to sixth codebooks.

[0306] In some embodiments, the terminal sending, to the network-side device, first phase-related information corresponding to the multiple measurement objects, includes:

[0307] The terminal jointly reports the first phase related information related to the same first delay related information; or

[0308] The terminal jointly reports the first phase related information corresponding to the measurement resources of the same measurement object; or

[0309] The terminal jointly reports the first phase related information corresponding to the multiple reported first delay related information; or

[0310] The terminal jointly reports a plurality of first phase related information corresponding to the same subband; or

[0311] The terminal jointly reports the first phase related information of the same type; or

[0312] The terminal jointly reports all the determined first phase related information.

[0313] In the embodiment of the present disclosure, first phase-related information corresponding to multiple measurement objects is sent to the network-side device, and the reporting form for joint reporting includes at least one of the following:

[0314] (1) The terminal jointly reports the first phase-related information related to the same first delay-related information. For example, the terminal may jointly report the phase difference corresponding to each determined delay difference.

[0315] (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 difference corresponding to the same measurement resource (or a measurement resource combination, which is a measurement resource combination formed by multiple measurement resource combinations).

[0316] (3) The terminal jointly reports the first phase-related information corresponding to the multiple first delay-related information reported. For example, the phase differences corresponding to the multiple delay differences reported by the UE can be jointly reported.

[0317] (4) The terminal jointly reports multiple pieces of the first phase-related information corresponding to the same sub-band, such as jointly reporting multiple phase differences corresponding to the same sub-band.

[0318] (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. The present disclosure can also jointly report different types of phase differences, such as the phase difference between type two and type three, where type two and type three are different.

[0319] (6) The terminal jointly reports all the determined first phase related information, such as jointly reporting all the phase differences.

[0320] In a specific implementation of the present disclosure, first phase-related information corresponding to multiple measurement objects is sent to a network-side device. The following phase difference reporting method may be used, where the first phase-related information is described using a phase difference, and the first delay-related information is described using a delay difference as an example:

[0321] Method 1: Each delay difference or the phase difference corresponding to each measurement resource (combination) can be jointly reported.

[0322] For example, the phase difference between measurement resource 1 and measurement resource 2 is The minimum phase is defined as When reporting phase, the UE can subtract all phase values Report later to reduce feedback overhead;

[0323] For example, the phase difference between measurement resource 1 and measurement resource 2 is The minimum phase is defined as When reporting phase, the UE can divide all phase values ​​by Report later to reduce feedback overhead;

[0324] For example, the phase difference between measurement resource 1 and measurement resource 2 is The minimum phase is defined as When reporting phase, the UE can divide all phase values ​​by Report later to reduce feedback overhead; or, The corresponding precoding matrix indexes are s, j, ..., p, etc., and the minimum phase is defined as When reporting the phase, the UE can subtract the precoding index corresponding to all phase values ​​from Report later to reduce feedback overhead.

[0325] Method 2: The phase differences corresponding to multiple delay differences reported by the UE can be reported jointly. For example, the phase differences corresponding to all delay differences reported in one report can be combined to determine the minimum phase difference. And remove all phase differences corresponding to all delay differences Report the impact after it is determined.

[0326] Method 3: Joint reporting is performed between multiple phase differences corresponding to a subband. For example, the number of measurement resources is 4, and the UE determines 3 phase differences for each subband. 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 subband, that is, jointly determine the minimum phase to be And remove the 3 phase differences Report the impact after it is determined.

[0327] Method 4: Joint reporting between different types of phase differences. For example, if the UE reports the phase difference used to eliminate time asynchronization and the phase difference used to eliminate reciprocity error, then joint reporting is performed within different types of phase differences. The UE determines the minimum phase among all phase differences within a phase difference type as And remove all phase differences within a phase difference type Report the impact after it is determined.

[0328] Method 5: All phase differences are reported jointly. For example, the UE determines that the minimum phase among all phase differences is And remove all phase differences Report the impact after it is determined.

[0329] In some embodiments, in each of the above phase difference joint reporting methods, the UE determines the maximum phase difference in a joint reporting as And remove all phase differences Report the impact after it is determined.

[0330] In some embodiments, the UE will Numeric or The value is reported to the network side; in some embodiments, the UE will 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 order of multiple delay difference reporting, the i-th reported delay difference index is i), or the corresponding measurement resource (combination) index is reported to the network side.

[0331] In some embodiments, the feedback granularity of the phase difference corresponding to each delay difference is different, that is, the feedback granularity of the phase difference is determined according to the size of each delay difference or the value of the phase difference. For example, if the UE reports 3 delay differences, the feedback granularity of the phase difference corresponding to each delay difference is K1 RB, K2 RB and K3 RB respectively; in addition, the phase difference feedback granularity corresponding to multiple delay differences can also be made the same, for example, the feedback granularity is determined according to the delay difference with the smallest feedback granularity or the corresponding phase difference to ensure that the phase difference reporting overhead corresponding to each delay difference is the same.

[0332] In the disclosed embodiment, after the delay difference and phase difference are jointly reported, differential reporting may be further performed on the phase difference corresponding to each delay difference, the phase difference corresponding to all delay differences, or the phase difference corresponding to each sub-band.

[0333] In some embodiments, the method of the present disclosure further comprises:

[0334] The terminal determines a maximum phase value or a minimum phase value in a set of jointly reported phase-related information, and preprocesses each first phase-related information in the set of jointly reported phase-related information based on the maximum phase value or the minimum phase value.

[0335] In the embodiment of the present disclosure, the terminal first determines the maximum phase value or the minimum phase value in a set of phase related information reported jointly, such as the minimum phase value through Indicates that the maximum phase value is obtained by Represents; Preprocessing each first phase related information in a set of phase related information reported jointly, specifically, subtracting or dividing all phases in a set of phase related information by the minimum phase value or maximum phase value Then report the resources to the network side device.

[0336] In some embodiments, the method of the present disclosure further comprises:

[0337] The terminal sends at least one of the following to the network side device:

[0338] The maximum phase value or the minimum phase value of each set of phase-related information;

[0339] The subband index corresponding to the maximum phase value or the minimum phase value in each set of phase related information;

[0340] the first delay related information index corresponding to the maximum phase value or the minimum phase value in each set of phase related information;

[0341] The measurement resource index corresponding to the maximum phase value or the minimum phase value in each set of phase-related information.

[0342] In the embodiment of the present disclosure, the UE can Numeric or The value is reported to the network side device; UE can 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 order of multiple delay difference reporting, the i-th reported delay difference index is i), or the corresponding measurement resource (combination) index is reported to the network side device.

[0343] In some embodiments, the amplitudes corresponding to the multiple measurement objects include at least one of the following:

[0344] a weighted value of the first delay related information;

[0345] a weighted value of the first phase-related information;

[0346] a weighting coefficient of the first delay related information;

[0347] A weighting coefficient of the first phase-related information.

[0348] In the present disclosure, the amplitude is correlated with the first time delay related information, or is correlated with the first phase related information. In one possible implementation, the first phase related information is determined based on the first time delay related information, and the weighting coefficient of the first time delay related information and the weighting coefficient of the first phase related information may be coefficients with equal values. When reporting the time delay and amplitude, the frequency domain equivalent phase difference can be determined by the weighting coefficient of the first time delay related information, which is used for eliminating time asynchrony or reciprocity error. When reporting the time delay, phase and amplitude, the frequency domain equivalent phase difference can be determined by the weighting coefficient of the first time delay related information and / or the weighting coefficient of the first phase related information, which is used for eliminating time asynchrony or reciprocity error.

[0349] For example, the first delay-related information is illustrated by the delay difference, and the measurement resource is illustrated by TRP. In some cases, multiple delay differences jointly determine the channel information between the TRP and the UE. For example, the UE reports four delay differences, which respectively represent the delay difference of the strongest path between TRP 1 and TRP 2, the delay difference between the strongest path of TRP 1 and the second strongest path of TRP 2, the delay difference between the second strongest path of TRP 1 and the strongest path of TRP 2, and the 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 based on multiple delay differences, the UE may further report weighting coefficients corresponding to multiple delay differences, that is, the weighting coefficients (i.e., amplitudes) of the first delay-related information.

[0350] The UE reports multiple delay differences for every two TRPs: the reporting format is one or more delays (differences) and one or more weighted values ​​(coefficients), where the number of delays (differences) and / or the number of weighted values ​​(also called the number of weighted coefficients, or the number of the strongest paths) is 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 delay difference between the 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 delay difference corresponding to two measurement resources is greater than a certain threshold value, the UE will report the corresponding delay difference, and will not report when the delay difference is less than the threshold value. In addition, the UE only reports the delay difference corresponding to different measurement resources (i.e., the delay difference between different TRPs), and does not report the delay difference between different paths within the same measurement resource.

[0351] In some embodiments, the terminal sending the amplitudes corresponding to the multiple measurement objects to the network-side device includes:

[0352] The terminal jointly reports the amplitude corresponding to the measurement resources of the same measurement object; or

[0353] The terminal jointly reports the amplitudes of the same type; or,

[0354] The terminal jointly reports the amplitude corresponding to the same first delay related information; or

[0355] The terminal jointly reports the amplitude corresponding to the same first phase related information; or

[0356] The terminal jointly reports the amplitudes corresponding to all the determined first delay related information; or

[0357] The terminal jointly reports the amplitudes corresponding to all the determined first phase related information; or

[0358] The terminal reports all the amplitudes.

[0359] In the embodiment of the present disclosure, the terminal can report the first delay related information and the amplitude. Specifically, in the various forms of the amplitude described below, the first delay related information includes the delay difference, which is expressed by 2πf j τ represents 2πf j The unit of τ is radian, or the delay difference is expressed by express.

[0360] In a specific implementation, the first delay-related information and amplitude are reported in at least one of the following forms:

[0361] (1) Weighted coefficient Ai , where A i Corresponding to the i-th delay difference; when the network side device receives the delay difference and 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) determines the equivalent phase difference in the frequency domain, which is used to eliminate time asynchrony or reciprocity errors. i Corresponding to the i-th delay difference, f j is the frequency corresponding to the j-th subcarrier or the j-th RB or the j-th subband, where the method for determining f0 is the same as the method for determining f0 above;

[0362] (2) Weighted coefficient B i , where B i Corresponding to the i-th delay difference; when the network side device receives the delay difference and weighting coefficient reported by the UE, it uses the following formula Determine the frequency domain equivalent phase difference for time desynchronization elimination or reciprocity error elimination;

[0363] (3) Weighted coefficient C i , where C i Corresponding to the i-th delay difference; after the network-side device receives the delay difference and weighting coefficient reported by the UE, it determines the equivalent delay difference according to the following formula C1τ1+C2τ2+C3τ3+C4τ4, which is used to eliminate time asynchrony;

[0364] (4) Weighted value A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) or weighted value The corresponding amplitude (i.e., D) or weighted value C1τ1+C2τ2+C3τ3+C4τ4 is calculated by the UE and reported to the network-side device;

[0365] (5) Weighted value A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) and weighting coefficient A i ;

[0366] (6) Weighted value The corresponding amplitude (ie D) and weighting coefficient B i ;

[0367] (7), weighted value C1τ1+C2τ2+C3τ3+C4τ4 and weighted coefficient C i .

[0368] Among them, the weighted value 2πf j τ k The components need to be modulo 2π, where k is the number of corresponding delays (differences), or the weighted values ​​can be obtained according to the above formula and then modulo 2π.

[0369] Furthermore, when reporting the delay difference and amplitude, when the delay difference and amplitude are reported only for two TRPs, the UE needs to further report whether the delay difference is the delay difference of measurement resource 1 relative to measurement resource 2, or the delay difference of measurement resource 2 relative to measurement resource 1, such as using 1 bit to indicate. When the delay difference is the 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 weighted coefficient reported by the UE, the network side device determines the frequency domain equivalent phase difference corresponding to the multiple delays, and then pre-compensates the downlink transmission signal corresponding to measurement resource 1, so that the signals sent by the TRPs corresponding to the two measurement resources arrive at the UE at the same time. Alternatively, in the case of TDD, the network side device can determine the frequency domain equivalent phase difference based on the delay difference reported by the UE, and determine the frequency domain channel corresponding to each RB or subband, such as Then, the precoding matrix of each subband is estimated, so that the estimated precoding corresponds to the channel information in the asynchronous case.

[0370] The UE reports multiple delays (differences) for multiple TRPs (one or more delay differences for every two measurement resources):

[0371] When the number of TRPs is greater than two, the UE reports multiple groups of delay differences. Each group of delay differences corresponds to one TRP or one measurement resource (combination). The reporting method for each group of delay differences and weighted values ​​and / or weighted coefficients is similar to the reporting method for delay differences corresponding to two TRPs. The number of weighted coefficients can be pre-defined in the protocol or pre-configured for the UE by the network-side equipment.

[0372] After receiving the report from the UE, the network side device determines the frequency domain equivalent phase difference corresponding to multiple delays and compensates the transmission signal of TRP so that the signals sent by multiple TRPs reach the UE at the same time; or the network side device constructs the channel information of each RB (or subband) according to the delay difference and amplitude. For example, the channel information corresponding to 4 TRPs is Then, the precoding matrix of each subband is estimated, so that the estimated precoding corresponds to the channel information in the asynchronous case.

[0373] In some embodiments, when the UE reports resource delay difference and amplitude to the network side device, the UE reporting format may be as shown in Table 3 below:

[0374] Table 3:

[0375] In some embodiments, the reporting format of the UE for reporting resources to the network side device may also be as shown in 4 below, where T represents the number of delay differences.

[0376] Table 4:

[0377] In some embodiments, the UE may also report an indication of the measurement resource (combination).

[0378] In some embodiments, when the amplitude adopts the above-mentioned weighted value or weighted coefficient, the reporting format of the UE may be:

[0379] Report the delay difference first, then the amplitude;

[0380] Report the delay difference and amplitude corresponding to one measurement resource (combination), and then report the delay difference and amplitude corresponding to other measurement resource combinations.

[0381] In another specific implementation manner, the first delay-related information, the first phase-related information, and the amplitude are reported in at least one of the following forms:

[0382] (1) Weighted coefficient A i , where A i Corresponding to the i-th delay difference; when the network side receives the delay difference and 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) determines the equivalent phase difference in the frequency domain, which is used to eliminate time asynchrony or reciprocity errors. i Corresponding to the i-th delay difference, f j is the frequency corresponding to the j-th subcarrier or j-th RB or j-th subband, where f j The method for determining f0 is the same as that for determining f0 above;

[0383] (2) Weighted coefficient B i , where B i Corresponding to the i-th delay difference; when the network side receives the delay difference and weighting coefficient reported by the UE, it uses the following formula Determine the frequency domain equivalent phase difference for time desynchronization elimination or reciprocity error elimination;

[0384] (3) Weighted value A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) or weighted value The corresponding amplitude (i.e. D) is calculated by the UE and reported to the network side;

[0385] (4) Weighted value A1(2πf j τ1)+A2(2πf j τ2)+A3(2πf j τ3)+A4(2πf j τ4) and weighting coefficient A i ;

[0386] (5) Weighted value The corresponding amplitude (ie D) and weighting coefficient B i ;

[0387] Among them, the weighted value 2πf j τ k The components need to be modulo 2π, where k is the number of corresponding delays (differences), or the weighted values ​​can be obtained according to the above formula and then modulo 2π.

[0388] In practice, the amplitude can be viewed as a combination coefficient between multiple delay differences or multiple phase differences. Therefore, the reporting method for the amplitude corresponding to the delay difference is similar to that for the phase difference. When the UE needs to report both the amplitudes (combining coefficients) corresponding to multiple delay differences and the amplitudes (combining coefficients) corresponding to multiple phase differences, the amplitudes corresponding to the delay differences and the amplitudes corresponding to the phase differences can be quantified separately.

[0389] In some embodiments, when the amplitude adopts the above-mentioned weighted value or weighted coefficient, the reporting format of the UE may be:

[0390] First report the delay difference, phase difference, and then the amplitude (the order of phase difference and amplitude can be reversed);

[0391] Report the delay difference, phase difference and amplitude corresponding to one measurement resource (combination), and then report the delay difference, phase difference and amplitude corresponding to other measurement resource combinations.

[0392] Accordingly, when both time synchronization error elimination and reciprocity error elimination 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. Use at least one of the following methods to handle this:

[0393] Method 1: The UE reports a set of delay differences and a set of phase differences. The delay differences are used to eliminate time asynchrony, and the phase differences are used to eliminate reciprocity errors.

[0394] Method 2: The UE reports one set of delay differences and two sets of phase differences. The delay difference and the first set of phase differences are used to eliminate time asynchrony, while the second set of phase differences is used to eliminate reciprocity errors.

[0395] Method 3: The UE reports two sets of delay differences and two sets of phase differences, where the first set of delay differences and the first set of phase differences are used to eliminate time asynchrony, and the second set of delay differences and the second set of phase differences are used to eliminate reciprocity errors, or the first set of delay differences and the first set of phase differences are used to eliminate reciprocity errors, and the second set of delay differences and the second set of phase differences are used to eliminate time asynchrony.

[0396] In some embodiments, the method of the present disclosure further comprises:

[0397] The terminal determines a maximum amplitude value among a set of jointly reported amplitude values, and pre-processes each amplitude value in the set of jointly reported amplitude values ​​based on the maximum amplitude value.

[0398] In the embodiment of the present disclosure, the terminal determines the maximum amplitude value among a group of amplitude values ​​reported jointly, and the maximum amplitude value can be obtained by d max Indicates that, based on the maximum amplitude d max , divide each amplitude in the set of jointly reported amplitudes by the maximum amplitude d max Reporting later can minimize feedback overhead.

[0399] In some embodiments, the amplitude reported by the UE may correspond to the first delay-related information (delay difference) or the first phase-related information (phase difference). In addition, the amplitude may also correspond to the measurement resource (combination).

[0400] In some embodiments, when the terminal reports the amplitude to the network side device, any of the following methods can be used:

[0401] The amplitude corresponding to each measurement resource (combination) is reported separately;

[0402] The amplitude of each type is reported separately;

[0403] The amplitude corresponding to each delay difference is reported separately;

[0404] The amplitude corresponding to each phase difference group is reported separately;

[0405] The amplitudes corresponding to all delay differences are reported separately;

[0406] The amplitudes corresponding to all phase differences are reported separately.

[0407] In some embodiments, the method of the present disclosure further comprises:

[0408] The terminal sends at least one of the following to the network side device:

[0409] The maximum amplitude of each group of amplitudes;

[0410] The subband index corresponding to the maximum amplitude in each group of amplitudes;

[0411] The delay difference index corresponding to the maximum amplitude in each group of amplitudes;

[0412] The measurement resource index corresponding to the maximum amplitude in each set of amplitudes.

[0413] In this disclosure, the UE calculates the d corresponding to each measurement resource (combination) s,max The value is reported to the network side device; UE also reports d s,max The corresponding subband index (or RB index or subcarrier index) is reported to the network side device.

[0414] In the embodiments of the present disclosure, when reporting amplitude, the terminal may send the amplitude to the network device in at least one of the following forms, depending on the amplitude form. In the following amplitude reporting methods 1 to 7, the first delay-related information is described using the delay difference as an example, and the first phase-related information is described using the phase difference as an example:

[0415] Method 1: The amplitude corresponding to each measurement resource (combination) is reported separately.

[0416] First, determine the maximum amplitude among the amplitudes corresponding to each measurement resource (combination) (e.g., 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. Let all amplitudes in the measurement resource (combination) s be divided by d s,max Then Q-bit quantization is performed. If Q = 1, 2, 3, or 4, quantization is performed according to Tables 5 to 8.

[0417] Table 5:

[0418] Table 6:

[0419] Table 7:

[0420] Table 8:

[0421] When a measurement resource (combination) includes both the amplitude corresponding to the delay difference and the amplitude corresponding to the phase difference, or includes both the amplitude corresponding to time asynchrony elimination and the amplitude corresponding to reciprocity error elimination, different types of amplitudes can be reported separately, see the following method 2 for amplitude reporting.

[0422] Method 2: Report the amplitude of each type separately.

[0423] For example, the amplitude corresponding to the delay difference is reported separately, the amplitude corresponding to the phase difference is reported separately, the amplitude corresponding to the time asynchrony elimination is reported separately, and the amplitude corresponding to the reciprocity error elimination is reported separately.

[0424] If each amplitude type corresponds to multiple measurement resources (combinations), first determine the maximum value among the amplitudes corresponding to all measurement resources (combinations) (e.g., d max ), let all amplitudes corresponding to one amplitude type be divided by d max Then Q-bit quantization is performed. If Q=1, 2, 3 and 4, quantization is performed according to Table 1-Table 4. In some embodiments, the UE will max In some embodiments, the UE also reports the value to the network side device. max The corresponding measurement resource (combination) and / or subband index (or RB index or subcarrier index) is reported to the network side device.

[0425] Method 3: The amplitude corresponding to each delay difference is reported separately.

[0426] First, determine the maximum value among the amplitudes corresponding to the delay differences (such as d max ), then all amplitudes corresponding to the delay difference are divided by d max Then Q bit quantization is performed. In some embodiments, the UE converts d max In some embodiments, the UE also reports the value to the network side device. max 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 order of multiple delay difference reporting, the i-th reported delay difference index is i), or the corresponding measurement resource (combination) index is reported to the network side device.

[0427] Method 4: The amplitude corresponding to each phase difference group is reported separately.

[0428] The so-called phase difference group refers to multiple phase differences corresponding to one delay difference (such as one phase difference for each subband, the phase differences of all subbands form a phase difference group, or a group of phase differences), or the phase difference corresponding to one measurement resource (combination).

[0429] First, determine the maximum value of the amplitude corresponding to a phase difference group (such as d max ), then all amplitudes corresponding to this phase difference group are divided by d max Then Q bit quantization is performed. In some embodiments, the UE converts d max In some embodiments, the UE also reports to the network side device. max 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 order of multiple delay difference reporting, the i-th reported delay difference index is i), or the corresponding measurement resource (combination) index is reported to the network side device.

[0430] Method 5: Report the amplitudes corresponding to all delay differences separately.

[0431] First, determine the maximum value among the amplitudes corresponding to all delay differences (such as d max ), then all amplitudes corresponding to the delay difference are divided by d max Then Q bit quantization is performed. In some embodiments, the UE converts d max In some embodiments, the UE also reports the value to the network side device. max 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 order of multiple delay difference reporting, the i-th reported delay difference index is i), or the corresponding measurement resource (combination) index is reported to the network side device.

[0432] Method 6: The amplitudes corresponding to all phase differences are reported separately.

[0433] First, determine the maximum value among all the amplitudes corresponding to the phase differences (such as d max ), then all amplitudes corresponding to the phase difference are divided by d max Then Q bit quantization is performed. In some embodiments, the UE converts d max In some embodiments, the UE also reports the value to the network side device. max 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 order of multiple delay difference reporting, the i-th reported delay difference index is i), or the corresponding measurement resource (combination) index is reported to the network side device.

[0434] Method 7: All amplitudes are reported jointly.

[0435] First determine the maximum value among all the amplitudes (such as d max ), then all amplitudes are divided by d max Then Q bit quantization is performed. In some embodiments, the UE converts d max In some embodiments, the UE also reports the value to the network side device. max 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 order of multiple delay difference reporting, the i-th reported delay difference index is i), or the corresponding measurement resource (combination) index is reported to the network side device.

[0436] It should be noted that, in this embodiment, the d reported by the UE max The corresponding subband index (or RB index or subcarrier index) or the corresponding delay difference index (such as the index value determined in the order of multiple delay difference reports, the delay difference index of the i-th report is i), or the corresponding measurement resource (combination) index, etc. and the subband index or measurement resource (combination) index corresponding to the delay difference or phase difference have different physical meanings, and may need to be reported at the same time in one report. max The corresponding index (such as the measurement resource (combination) index), and the index corresponding to the delay difference or phase difference (such as the measurement resource (combination) index).

[0437] In one specific implementation, the UE reports first delay-related information and first phase-related information to a network-side device, respectively. Here, 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 separately. The UE does not need to determine the phase difference based on the delay difference, but rather independently determines the delay difference and the phase difference. After the UE reports the delay difference to the network-side device, the network-side device may perform joint processing or pre-compensation based on the delay difference and phase difference reported by the UE.

[0438] The UE can use the following differential method or non-differential method to report the delay difference:

[0439] Reporting delay difference using the differential method: If the UE measures and reports the measurement resources corresponding to four TRPs, the three measured delay differences are, 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. Assuming that τ2 has the smallest value among the three delay differences, that is, τ2 = min(τ1,τ2,τ3), the UE can report τ2, (τ1-τ2), and (τ3-τ2). The reporting overhead of (τ1-τ2) and (τ3-τ2) will be lower than the reporting overhead of non-differential delay differences (such as τ1,τ2,τ3), thereby reducing feedback overhead.

[0440] For example, the non-differential delay difference (such as τ2) is quantized using T1 bits, and the differential delay difference (such as (τ1-τ2) and (τ3-τ2)) is quantized using T2 bits, where T1>T2.

[0441] Non-differential method for reporting delay differences: Taking the reporting of three delay differences corresponding to four TRPs as an example, the UE reports the delay differences in ascending order or descending order, and each delay difference is quantized using T1 bits.

[0442] In some embodiments, the UE reports the measurement resource (combination) index corresponding to each delay difference (differential or non-differential delay difference).

[0443] In an optional embodiment, the terminal sending, to the network-side device, first delay-related information corresponding to the multiple measurement objects, includes:

[0444] The terminal determines reference delay related information from the plurality of first delay related information;

[0445] determining, by the terminal, differences between a plurality of first delay-related information and the reference delay-related information;

[0446] The terminal sends the difference and the reference delay related information.

[0447] In an embodiment of the present disclosure, reference delay related information is determined based on multiple first delay related information, and the reference delay related information is a reference object in the multiple first delay related information, such as the multiple first delay related information include: TRP 1, TRP 2, TRP 3 and TRP 4, wherein any one of TRP 1, TRP 2, TRP 3 and TRP 4 can be used as reference delay related information; further calculate the difference between the multiple first delay related information and the reference delay related information, the terminal sends the difference and the reference delay related information, and the corresponding network side device can determine how many first delay related information exist.

[0448] In a specific embodiment, when a terminal reports multiple first delay-related information and multiple first phase-related information, the first delay-related information is described using a delay difference as an example, and the first phase-related information is described using a phase difference distance. 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.

[0449] For example, in a measurement report, the number of TRPs is 4, namely TRP 1, TRP 2, TRP 3 and TRP 4, then the number of measurement resources or measurement resource ports is 4, and the UE determines 3 delay differences based on this measurement resource or measurement resource port, which respectively represent the delay difference 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; for another example, the UE reports multiple groups of delay differences, such as the delay difference between other measurement resources and measurement resource 1 with reference to measurement resource 1; the delay difference between other measurement resources and measurement resource 2 with reference to measurement resource 2; the delay difference between other measurement resources and measurement resource 3 with reference to measurement resource 3; the delay difference between other measurement resources and measurement resource 4 with reference to measurement resource 4; in this case, the UE reports a total of 12 delay differences, which respectively represent:

[0450] 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;

[0451] 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;

[0452] 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;

[0453] The delay difference between measurement resource 1 and measurement resource 4, the delay difference between measurement resource 2 and measurement resource 4, and the delay difference between measurement resource 3 and measurement resource 4 are measured.

[0454] In some embodiments, the terminal sending, to the network-side device, first delay-related information corresponding to the multiple measurement objects, includes:

[0455] The terminal reports the plurality of first delay related information sequentially based on a preset sorting strategy.

[0456] In the embodiment of the present disclosure, since there are multiple delay differences reported, it is necessary to determine the correspondence between the delay differences and the measurement resources or measurement resource ports. The preset sorting strategy can be to order the delay differences from small to large or from large to small. For example, the UE reports the delay differences in order from small to large or from large to small, and indicates the measurement resource (absolute or relative) index or measurement resource port (absolute or relative) index corresponding to the delay difference. Because a 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 delay difference can also be determined by permutation and combination or a predefined method.

[0457] For example, a measurement resource set contains four measurement resources, and there are 4*3*2*1=24 possible permutations of the four measurement resources. (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 combinations, as this affects the correspondence between the reported delay inequality and the measurement resources. In this case, the UE can use 5 bits to report which of the 24 combinations corresponds to the delay inequality. Alternatively, a smaller set of combinations reported by the UE can be predefined, 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), and (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 delay inequality. The measurement resource combinations allowed to be reported may also be configured by the network side device.

[0458] In some embodiments, the present disclosure, in the case where there are greater than or equal to 2 measurement resources, each measurement resource corresponds to one or more first delay-related information or first phase-related information, takes the measurement resource with TRP, the first delay-related information as the delay difference and the first phase-related information as the phase difference as an example, to further illustrate the steps of jointly reporting the delay difference and the phase difference.

[0459] For example, both the delay difference and the phase difference are reported in one report, where the phase difference can be the residual phase difference after removing the effect of the delay difference. Taking the delay difference and phase difference corresponding to two TRPs as an example, if the UE feeds back a delay (difference) corresponding to two TRPs, calculated as τ, the phase (difference) corresponding to τ can have the following forms:

[0460] Form 1: 2πf j τ, in radians;

[0461] Form 2:

[0462] Form 3:

[0463] Among them, form three is a vector form, 1 means that the phase (difference) between TRP 1 and TRP 1 is 0, Indicates that the phase (difference) between TRP 2 and TRP 1 is 2πf jIn essence, only form 1 is the phase (difference). Forms 2 and 3 are used to reduce feedback overhead. For example, by feeding back the precoded codeword in the precoding codebook (corresponding to form 3), both the base station and the UE can determine the corresponding phase (difference) based on the precoded codeword.

[0464] If the UE measures the phase difference between two TRPs in the frequency domain, such as or On this basis, we can further reduce the influence of the phase difference corresponding to the time delay (such as 2πf j τ, or ), the feedback overhead is further reduced by reducing the value of the phase difference.

[0465] The present disclosure reports one delay difference and multiple phase differences, wherein the delay difference is the delay difference between 2 TRPs or 2 measurement resources, and the phase difference is the phase difference between each subband or PRB or PRB group in the frequency domain.

[0466] In this embodiment, the sub-band granularity of the phase difference reporting is B PRBs, where B is reported by the UE to the network side device. It should be noted that the sub-band granularity of the phase difference reporting and the PMI reporting granularity defined in the 5G NR protocol can be the same or different. The sub-band granularity needs to match the change in phase difference to ensure that the phase difference reported in a sub-band is applicable to the entire sub-band. In the present disclosure, the UE measures the phase difference and reports the reporting granularity of the phase difference. The sub-band granularity for reporting the phase difference (also called the first sub-band granularity) can be 0.5 PRB, 1 PRB, 2 PRBs, 3 PRBs, 4 PRBs, ..., 32 PRBs, ..., 64 PRBs, etc.

[0467] When the delay difference is τ, the reported phase difference is the measured phase difference minus mod(2πf0τ,2π) (if the phase difference is repeatedly quantized according to the first quantization method; or the phase difference is the measured value divided by After (such as phase difference form 2 or form 3), the value is quantized 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 is transformed to [0,2π], and The phase (difference) of the corresponding measurement has no requirements on the phase, and there is no need to convert the phase to [0, 2π].

[0468] In some embodiments, the present disclosure reports multiple delay differences and multiple phase differences, wherein the terminal reports resources to the network side device, each delay difference corresponds to one or more phase differences, and the reporting format of the UE reporting resources to the network side device can be as shown in Table 9 below:

[0469] Table 9:

[0470] The reporting format for the UE to report resources to the network side device may also be as shown in the following Table 10, where T represents the number of delay differences.

[0471] Table 10:

[0472] The phase difference reported in the present disclosure is the measured phase difference minus the phase value corresponding to the corresponding delay difference, and then quantized according to the first quantization method, or the phase difference is the measured value divided by the frequency domain value corresponding to the corresponding delay difference (equivalent to the value in the exponential domain), and then quantized according to the second quantization method or quantization codebook.

[0473] In some embodiments, the method of the present disclosure further includes:

[0474] When sending the first phase-related information to the network-side device, the terminal sends information about a quantized phase range to be used;

[0475] When sending the first delay-related information to the network-side device, the terminal sends information on a quantified used time range.

[0476] In the embodiment of the present disclosure, when the network side device performs quantization codebook calculation, whether it is the first quantization method or the second quantization method mentioned above, it is necessary to use the information of the phase range corresponding to the quantization or the information of the time range used for quantization. When sending the first phase-related information or the first delay-related information, the phase range and time range are sent, which is beneficial to reducing the time of subsequent quantization processing.

[0477] In some embodiments, the phase range or the time range includes at least one of the following:

[0478] [0, a];

[0479] [a, b];

[0480] [-a, 0];

[0481] [-a, b];

[0482] Range number w, the range corresponding to w is pre-defined in the protocol;

[0483] Where a and b are positive numbers;

[0484] The terminal reports information about the phase range or time range used for sending quantization, including:

[0485] The terminal sends at least one of a, b and w.

[0486] In the embodiment of the present disclosure, the terminal sends at least one of a, b and w, which can cause the UE to feedback the reporting range of the frequency domain phase difference, such as the range of [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. Alternatively, the phase difference is quantized in a uniform quantization manner, such as the reporting range and the reporting granularity are both pre-specified by the protocol. The purpose of setting the phase range or time range as mentioned above is to achieve higher-precision reporting with less signaling overhead.

[0487] In summary, the terminal-side measurement reporting method of the disclosed embodiment is used to report at least two of the delay difference, phase difference, and amplitude between multiple measurement objects. This method can accurately eliminate the time difference, phase difference, or reciprocity error between multiple measurement objects.

[0488] 2 , an embodiment of the present disclosure further provides a measurement reporting method, including:

[0489] In step 21, the terminal determines multiple measurement objects.

[0490] In the present disclosure, the measurement object may be a measurement resource, a measurement resource port, or the like. For example, one measurement resource includes multiple measurement resource ports, and the multiple measurement objects may be multiple measurement resource ports of the one measurement resource. Alternatively, the multiple measurement objects may be multiple measurement resources or multiple resource ports corresponding to multiple measurement resources, or the multiple measurement objects may be multiple measurement resource sets. For another example, one measurement resource port corresponds to one TRP, and multiple measurement objects may be represented as multiple TRPs, which is not limited in the present disclosure.

[0491] Step 22: The terminal sends first delay-related information or first phase-related information corresponding to the multiple measurement objects to a network-side device;

[0492] Step 23: When sending the first phase-related information to the network-side device, the terminal sends information about a phase range used for quantization;

[0493] Step 24: When sending the first delay-related information to the network-side device, the terminal sends information about a quantified used time range.

[0494] In the disclosed embodiment, unlike the terminal-side implementation method described above, in step 22, the terminal sends first delay-related information or first phase-related information to the network-side device. This helps reduce feedback overhead based on the first delay-related information or the first phase-related information. Because the network-side device, when performing quantization codebook calculations, requires information about the phase range corresponding to quantization or the time range used for quantization, when sending the first phase-related information or the first delay-related information, sending the phase range and time range helps reduce the time for subsequent quantization processing.

[0495] In some embodiments, the phase range or the time range includes at least one of the following:

[0496] [0, a];

[0497] [a, b];

[0498] [-a, 0];

[0499] [-a, b];

[0500] Range number w, the range corresponding to w is pre-defined in the protocol;

[0501] Where a and b are positive numbers;

[0502] The terminal reports information about the phase range or time range used for sending quantization, including:

[0503] The terminal sends at least one of a, b and w.

[0504] In some embodiments, the quantization granularity or the number of quantization values ​​in different phase ranges or different time ranges are different, wherein the quantization granularity value or the number of quantization values ​​corresponding to the phase range or time range is pre-specified by the protocol.

[0505] In the embodiment of the present disclosure, the terminal sends at least one of a, b and w, which can cause the UE to feedback the reporting range of the frequency domain phase difference, such as the range of [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. Alternatively, the phase difference is quantized in a uniform quantization manner, such as the reporting range and the reporting granularity are both pre-specified by the protocol. The purpose of setting the phase range or time range as mentioned above is to achieve higher-precision reporting with less signaling overhead.

[0506] In some embodiments, the first phase-related information is determined according to at least one of the following codebooks:

[0507] A first codebook, wherein the first codebook includes N-1 W1s, and each of the N-1 W1s is different.

[0508] A second codebook, wherein the second codebook includes P-1 W2, and each W2 in the P-1 W2 is different, The value of P is configured by high-level parameters and is less than or equal to N.

[0509] A third codebook, wherein the third codebook includes N-1 W3, and each W3 in the N-1 W3 is different,

[0510] A fourth codebook, wherein the fourth codebook includes N1-1 W4s, and each of the N1-1 W4s is different. Among them, N p The value of is predefined by the high-level parameter configuration or protocol, p = 1, 2, ..., K-1;

[0511] A fifth codebook, wherein the fifth codebook includes P-1 W5s, and each of the P-1 W5s is different. The value of P is configured by high-level parameters and is less than or equal to N.

[0512] A sixth codebook, wherein the sixth codebook includes P1-1 W6, and each W6 in the P1-1 W6 is different, Among them, P q The value of is configured by high-level parameters, q = 1, 2, ..., K-1;

[0513] Wherein, N is a positive integer and K is determined by the number of measurement objects.

[0514] In the disclosed embodiment, when the number of measurement objects (e.g., the number of TRPs, the number of measurement resources, or the number of measurement resource ports) is 2, the quantization codebook can be represented by a first codebook, where i in the first codebook represents a 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 downlink channel information based on the precoding codeword.

[0515] In one implementation, the phase difference reported by the UE undergoes a differential operation, so only some precoding codewords may be reported. One method is to configure a subset restriction for measurement reporting for the UE, such as using N bits to configure which precoding codewords the UE can report through bit mapping; for example, let i take the value of 0, 1, 2, …, P-1, where the value of P is configured by a high-level parameter.

[0516] Another method is to report by using the above-mentioned second codebook. The value of P in the above-mentioned second codebook is configured by a high-level parameter. 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 expressed in the form of the above-mentioned third codebook or the form of the above-mentioned fourth codebook. In the third codebook, the quantization method of 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 may be different.

[0517] Similarly, the phase difference can be reported by limiting the codebook subset or using a new codebook to reduce the feedback overhead. The form of the quantized codebook can be expressed in the form of the fifth codebook or the sixth codebook. k The value of (k=1, 2, ..., K-1) is configured by high-level parameters.

[0518] In some embodiments, the terminal sending, to the network-side device, first phase-related information corresponding to the multiple measurement objects, includes:

[0519] The terminal jointly reports the first phase related information related to the same delay related information; or

[0520] The terminal jointly reports the first phase related information corresponding to the measurement resources of the same measurement object; or

[0521] The terminal jointly reports a plurality of first phase related information corresponding to the same subband; or

[0522] The terminal jointly reports the first phase related information of the same type; or

[0523] The terminal jointly reports all the determined first phase related information.

[0524] In the embodiment of the present disclosure, first phase-related information corresponding to multiple measurement objects is sent to the network-side device, and the reporting form for joint reporting includes at least one of the following:

[0525] (1) The terminal jointly reports the first phase-related information related to the same first delay-related information. For example, the terminal may jointly report the phase difference corresponding to each determined delay difference.

[0526] (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 difference corresponding to the same measurement resource (or a measurement resource combination, which is a measurement resource combination formed by multiple measurement resource combinations).

[0527] (3) The terminal jointly reports the first phase-related information corresponding to the multiple first delay-related information reported. For example, the phase differences corresponding to the multiple delay differences reported by the UE can be jointly reported.

[0528] (4) The terminal jointly reports multiple pieces of the first phase-related information corresponding to the same sub-band, such as jointly reporting multiple phase differences corresponding to the same sub-band.

[0529] (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. The present disclosure can also jointly report different types of phase differences, such as the phase difference between type two and type three, where type two and type three are different.

[0530] (6) The terminal jointly reports all the determined first phase related information, such as jointly reporting all the phase differences.

[0531] It should be noted that the embodiment of the measurement reporting method on the terminal side corresponding to FIG1 may also be applicable to the method of the present disclosure, and will not be described in detail here.

[0532] In summary, the terminal-side measurement reporting method of the embodiment of the present disclosure is used to report the delay difference or phase difference between multiple measurement objects. This method can reduce the amount of data calculation and reduce the terminal-side overhead.

[0533] 3 , the present disclosure also provides a measurement acquisition method, including:

[0534] In step 31, a network-side device receives first delay-related information and first phase-related information corresponding to a plurality of measurement objects sent by a terminal; wherein the first delay-related information is related to the first phase-related information.

[0535] In the present disclosure, the network-side device may configure multiple measurement resources for the UE. The measurement resources may be CSI-RS resources, SSB resources, TRS resources, etc. Multiple measurement resources may be configured in one measurement resource set (such as a CSI-RS resource set) or in multiple measurement resource sets. This disclosure does not impose any restrictions on this. One measurement resource, or multiple measurement resources in a measurement resource set, corresponds to one TRP.

[0536] In an embodiment of the present disclosure, a network-side device receives first delay-related information corresponding to multiple measurement objects, and sends first phase-related information related to the first delay-related information, sent by a terminal. The first delay-related information may be a measured delay or a delay obtained by first measuring and then processing. The first phase-related information may be calculated from the measured phase and the corresponding measured delay. By simultaneously receiving correlated delays and phases, the network-side device performs preprocessing to preemptively eliminate delay or phase differences between the multiple measurement objects, thereby reducing feedback overhead.

[0537] In some embodiments, in an embodiment of the present disclosure, 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, or 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 quantified independently. It should be noted that although the two can be reported independently of each other, there is a correlation between the two, that is, the first delay-related information is related to the first phase-related information. For example, 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.

[0538] In some embodiments, the network-side device receives amplitudes corresponding to the multiple measurement objects sent by the terminal.

[0539] In an embodiment of the present disclosure, while receiving first delay-related information and first phase-related information, amplitudes corresponding to multiple measurement objects are received, where the amplitudes can be amplitudes corresponding to multiple first delay-related information or amplitudes corresponding to multiple first phase-related information. The present disclosure 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. This method can accurately eliminate time differences, phase differences, or reciprocity errors between multiple TRPs.

[0540] In some embodiments, when a network-side device receives a measurement report from a terminal, it may receive at least two items of first delay-related information, first phase-related information, and amplitude between multiple measurement objects. For example, the present disclosure may receive the first delay-related information and the first phase-related information for joint reporting; or it may receive measurement reports of the first delay-related information and amplitude separately.

[0545] A third codebook, wherein the third codebook includes N-1 W3, and each W3 in the N-1 W3 is different,

[0546] A fourth codebook, wherein the fourth codebook includes N1-1 W4s, and each of the N1-1 W4s is different. Among them, N p The value of is predefined by the high-level parameter configuration or protocol, p = 1, 2, ..., K-1;

[0547] A fifth codebook, wherein the fifth codebook includes P-1 W5s, and each of the P-1 W5s is different. The value of P is configured by high-level parameters and is less than or equal to N.

[0548] A sixth codebook, wherein the sixth codebook includes P1-1 W6, and each W6 in the P1-1 W6 is different, Among them, P q The value of is configured by high-level parameters, q = 1, 2, ..., K-1;

[0549] Wherein, N is a positive integer and K is determined by the number of measurement objects.

[0550] In the disclosed embodiment, when the number of measurement objects (e.g., the number of TRPs, the number of measurement resources, or the number of measurement resource ports) is 2, the quantization codebook can be represented by a first codebook, where i in the first codebook represents a 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 downlink channel information based on the precoding codeword.

[0551] In one implementation, the phase difference reported by the UE is subjected to a differential operation, so only some precoding codewords can be reported. One method is to configure a subset restriction of the measurement report for the UE, such as using N bits to configure which precoding codewords the UE can report through bit mapping; for example, let i take the value of 0, 1, 2, ..., P-1, where the value of P is configured by a high-level parameter. Another method is to report in the form of the above-mentioned second codebook. The value of P in the above-mentioned second codebook is configured by a high-level parameter. 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 expressed in the form of the above-mentioned third codebook or the above-mentioned fourth codebook. In the third codebook, the quantization method of 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 may be different.

[0552] Similarly, the phase difference can be reported by limiting the codebook subset or using a new codebook to reduce the feedback overhead. The form of the quantized codebook can be expressed in the form of the fifth codebook or the sixth codebook. k The value of (k=1, 2, ..., K-1) is configured by high-level parameters.
