[0051] The following description, in conjunction with the accompanying drawings, details a capability information reporting method, receiving method, terminal, and network-side device provided in this application through some embodiments and application scenarios.

[0052] Please see Figure 2 , Figure 2 This is a flowchart of a capability information reporting method provided in an embodiment of this application, such as... Figure 2 As shown, it includes the following steps:

[0053] Step 201: The terminal performs a capability reporting operation, which includes reporting first indication information. The first indication information is used to indicate whether a first capability is supported. The first capability includes: performing Layer 1 mobility measurement based on CSI-RS in a first cell; wherein the frequency domain resources occupied by the CSI-RS in the first cell include frequency domain resources within a first bandwidth, and the first cell also satisfies at least one of the following:

[0054] The timing difference between the cells corresponding to the first cell is greater than the CP.

[0055] The frequency domain resources occupied by the CSI-RS of the first cell include the frequency domain resources other than the active BWP of the serving cell of the terminal.

[0056] The aforementioned reporting of the first instruction information refers to sending the first instruction information to the network-side device.

[0057] The aforementioned first cell can represent a cell whose frequency domain resources occupied by CSI-RS include those within the first bandwidth, and which satisfies at least one of the following conditions:

[0058] The timing difference between the corresponding cells is greater than the CP.

[0059] The frequency domain resources occupied by CSI-RS include the frequency domain resources other than the active BWP of the serving cell of the terminal.

[0060] In this embodiment of the application, there may be one or more first cells, or a set of first cells.

[0061] In some implementations, the first cell may be a neighboring cell of the serving cell.

[0062] The frequency domain resources occupied by the aforementioned CSI-RS, including those within the first bandwidth, may include:

[0063] A portion of the frequency domain resources occupied by CSI-RS are within the first bandwidth; or

[0064] All frequency domain resources occupied by CSI-RS are within the first bandwidth.

[0065] For example: CSI-RS has at least X resource blocks (RBs) or resource elements (REs) within the first bandwidth, where X is a positive integer greater than or equal to 1; or,

[0066] All RBs or REs in CSI-RS are within the first bandwidth.

[0067] The aforementioned first bandwidth may be the bandwidth assumed by the terminal, the bandwidth reported by the terminal to the network-side device, the bandwidth indicated by the network-side device, or the bandwidth agreed upon in the protocol, etc.

[0068] The aforementioned inter-cell reception timing difference can be the reception timing difference between the first cell and the serving cell, or the reception timing difference between the first cell and the neighboring cells of the serving cell. In the case of multiple first cells, the aforementioned inter-cell reception timing difference can be the reception timing difference between the first cells themselves.

[0069] The frequency domain resources occupied by the aforementioned CSI-RS, excluding the active BWP of the serving cell of the terminal, may include:

[0070] A portion of the frequency domain resources occupied by CSI-RS are located outside the active BWP of the terminal's serving cell; or

[0071] All frequency domain resources occupied by CSI-RS are located outside the active BWP of the terminal's serving cell.

[0072] In this embodiment of the application, the above-mentioned CSI-RS-based Layer 1 mobility measurement can also be referred to as CSI-RS-based Layer 1 measurement.

[0073] In this embodiment of the application, the first capability includes: performing CSI-RS-based Layer 1 mobility measurement in the first cell, thereby enabling support for CSI-RS-based Layer 1 mobility measurement in the communication system. For example, if some or all terminals support CSI-RS-based Layer 1 mobility measurement, it will help improve the communication performance of the communication system.

[0074] In addition, since the frequency domain resources occupied by the CSI-RS of the first cell include the frequency domain resources within the first bandwidth, and the first cell also satisfies at least one of the following: the reception timing difference between the cells corresponding to the first cell is greater than the CP; the frequency domain resources occupied by the CSI-RS of the first cell include the frequency domain resources other than the active BWP of the serving cell of the terminal, it is possible to expand the cells for CSI-RS-based Layer 1 mobility measurement, so that the terminal can perform CSI-RS-based Layer 1 mobility measurement in more cells, thereby improving the measurement performance of the terminal.

[0075] As an optional implementation, the method further includes:

[0076] The terminal performs Layer 1 mobility measurements based on CSI-RS in the first cell.

[0077] As an optional implementation, if the terminal does not report the first indication information, it indicates that the terminal does not support the first capability.

[0078] This allows the terminal to be instructed not to support the first capability by not reporting it, thus saving transmission overhead.

[0079] As an optional implementation, the first capability includes:

[0080] If the serving cell of the terminal belongs to the first frequency band combination, a Layer 1 mobility measurement based on CSI-RS is performed in the first cell.

[0081] The aforementioned first frequency band combination is the first frequency band combination corresponding to the aforementioned first capability.

[0082] In some implementations, the first frequency band combination may be a carrier aggregation (CA) bandwidth combination. In addition to identifying the carrier aggregation band corresponding to the first capability, the bandwidth combination also identifies the maximum number of aggregated carrier bandwidths supported in each frequency band.

[0083] In some implementations, the aforementioned first frequency band combination may be a frequency band combination determined by the terminal, agreed upon by the protocol, or configured by the network-side equipment.

[0084] When the serving cell of the terminal belongs to the first frequency band combination, performing Layer 1 mobility measurement based on CSI-RS in the first cell can be performed when all or part of the serving cells of the terminal belong to the first frequency band combination.

[0085] In the above embodiments, since the serving cell of the terminal belongs to the first frequency band combination, the CSI-RS-based layer 1 mobility measurement is performed in the first cell, which can improve the measurement reliability.

[0086] In some implementations, it is not necessary to limit the serving cell of the terminal to the first frequency band combination.

[0087] As an optional implementation, the first cell mentioned above belongs to the first frequency band combination.

[0088] Since the first cell belongs to the first frequency band combination, it is possible to measure neighboring cells that belong to the same frequency band combination as the serving cell. This allows full use of the radio frequency resources provided by the terminal to support carrier aggregation of the frequency band combination, thereby improving measurement efficiency.

[0089] The step of performing Layer 1 mobility measurement based on CSI-RS in the first cell further includes ensuring that the measurement result of the terminal performing Layer 1 mobility measurement based on CSI-RS in the first cell meets a first requirement.

[0090] The first requirement mentioned above is stipulated in the agreement. For example, the first requirement includes at least the following: under a signal-to-noise ratio (Es / IoT) of -3dB, the measurement accuracy error of the reference signal received power (RSRP) is less than 9dB or 6dB, or under a signal-to-noise ratio (Es / IoT) of -3dB, the measurement accuracy error of the reference signal received quality (RSRQ) is less than 9dB or 6dB.

[0091] In some implementations, the first requirement is the measurement requirement that the terminal must meet when performing Layer 1 mobility measurement based on CSI-RS in the first cell, provided that the frequency domain resources occupied by the CSI-RS are not less than 48 RBs.

[0092] For example: The terminal reports a first indication message, which indicates whether the terminal supports a first capability. The first capability may include...

[0093] When all serving cells of the terminal belong to the first frequency band combination corresponding to the first capability, the terminal performs a Layer 1 mobility measurement based on CSI-RS on the first cell set, and the measurement result meets the first requirement, wherein the first cell in the first cell set meets the first condition, and the first condition includes at least one of the following:

[0094] The first reception timing difference between cells is greater than the CP, and the CSI-RS covers at least the first bandwidth;

[0095] The CSI-RS corresponding to the first cell is outside the active BWP of all serving cells and covers at least the first bandwidth;

[0096] The first cell is also located within the frequency band combination corresponding to the first capability.

[0097] Among them, the first cell in the aforementioned first cell set is the neighboring cell of the serving cell.

[0098] In some implementations, the measurement results may not be limited.

[0099] As an optional implementation, the capability reporting operation further includes:

[0100] The terminal reports a second indication information, which is used to indicate whether a second capability is supported. The second capability includes: performing Layer 1 mobility measurement based on CSI-RS in a second cell; wherein the reception timing difference between the cells corresponding to the second cell is less than or equal to the CP, and the frequency domain resources occupied by the CSI-RS of the second cell include the frequency domain resources within the active BWP of the serving cell of the terminal.

[0101] The second instruction information and the first instruction information are reported through different messages.

[0102] The frequency domain resources occupied by the aforementioned CSI-RS, including those within the active BWP of the serving cell of the terminal, may include:

[0103] The frequency domain resources occupied by CSI-RS are partly located within the active BWP of the serving cell of the terminal; or...

[0104] All frequency domain resources occupied by CSI-RS are located within the active BWP of the serving cell of the terminal.

[0105] The second community mentioned above refers to communities that meet the following conditions:

[0106] The corresponding inter-cell reception timing difference is less than or equal to CP, and the frequency domain resources occupied by CSI-RS include the frequency domain resources within the active BWP of the serving cell of the terminal.

[0107] The aforementioned second reporting information can support Layer 1 mobility measurement based on CSI-RS in the second cell, thereby expanding the measurement range of Layer 1 mobility measurement based on CSI-RS. For example, if the terminal does not support the first capability, Layer 1 mobility measurement based on CSI-RS can be performed in the second cell.

[0108] In some implementations, if the terminal supports the first capability, the terminal also supports the second capability; or

[0109] If the terminal does not support the first capability, the terminal may or may not support the second capability.

[0110] The above-mentioned support for the second capability by the terminal when the terminal supports the first capability can be understood as follows: if the terminal supports the first capability, then the terminal supports the second capability. For example: Figure 3 As shown, the measurement range supporting Layer 1 mobility measurement of the first capability terminal based on CSI-RS includes the measurement range corresponding to the second capability.

[0111] Since the terminal supports the second capability when it supports the first capability, the terminal can have a wider measurement range for Layer 1 mobility measurement based on CSI-RS, thereby further improving the measurement performance of the terminal.

[0112] If the terminal does not support the first capability, the terminal supports the second capability, so that the terminal can perform Layer 1 mobility measurement based on CSI-RS in the second cell to improve the measurement performance of the terminal.

[0113] For example: The terminal reports a second indication information, which indicates whether a second capability is supported. The second capability includes:

[0114] When all serving cells of the terminal belong to the frequency band combination corresponding to the second capability, the terminal can perform Layer 1 mobility measurement based on CSI-RS on the second cell set, and the measurement result meets the first requirement, wherein the second cell in the second cell set meets the second condition, and the second condition includes at least one of the following:

[0115] The first reception timing difference between cells is less than the CP;

[0116] The CSI-RS corresponding to Zone 2 is within the active BWP of all serving cells.

[0117] The second cell in the aforementioned second cell set does not satisfy the first condition in the above implementation method.

[0118] If a terminal reports support for the first capability, it must also report support for the second capability.

[0119] As an optional implementation, the method further includes:

[0120] The terminal performs Layer 1 mobility measurements based on CSI-RS in the second cell.

[0121] As an optional implementation, the parameter of the first bandwidth is determined by the configuration sent by the network-side device to the terminal.

[0122] The parameters of the first bandwidth mentioned above can be the number of resources in the first bandwidth, such as the number of RBs or REs, or the start position or end position, etc.

[0123] Since the parameters of the first bandwidth are determined by the configuration sent by the network-side device to the terminal, the first bandwidth can be flexibly configured by the network-side device.

[0124] As an optional implementation, the first bandwidth is the frequency domain resource occupied by the SSB associated with the CSI-RS; or,

[0125] The first bandwidth covers the frequency domain resources occupied by the SSB associated with the CSI-RS.

[0126] In some implementations, the SSB associated with the CSI-RS can be an SSB that has a synchronization relationship with the CSI-RS. This synchronization relationship can be a quasi-co-location (QCL) relationship, such as when the network-side device configures the network to have a QCL relationship between the SSB and the CSI-RS.

[0127] The first bandwidth mentioned above is the frequency domain resource occupied by the SSB associated with the CSI-RS. In this way, only one set of fast Fourier transform (FFT) cell search modules with the same bandwidth as the SSB needs to be designed. In addition to the SSB, the signal of the CSI-RS can also be sent into the cell search module, thus reducing the complexity of the terminal.

[0128] The aforementioned first bandwidth covering the frequency domain resources occupied by the SSB associated with the CSI-RS may include:

[0129] A portion of the frequency domain resources in the first bandwidth overlap with the frequency domain resources occupied by the SSB associated with CSI-RS;

[0130] All frequency domain resources in the first bandwidth overlap with the frequency domain resources occupied by the SSB associated with CSI-RS.

[0131] Since the first bandwidth covers the frequency domain resources occupied by the SSB associated with the CSI-RS, multiple FFT cell search modules with a bandwidth slightly larger than that of the SSB can be used without designing multiple FFT cell search modules for the entire CSI-RS bandwidth, thereby reducing the complexity of the terminal.

[0132] As an optional implementation, the first indication information is also used to indicate the range of values ​​for the number of RBs of the first bandwidth supported by the terminal.

[0133] In this embodiment, the first bandwidth can be determined by the terminal's report. The range of the number of RBs in the first bandwidth can represent the width information of the first bandwidth, and the specific location information can be determined by the network-side device configuration.

[0134] In this embodiment, since the range of the number of RBs in the first bandwidth is determined by the terminal, the first bandwidth can be made more suitable for the terminal, thereby improving the terminal's measurement performance.

[0135] Furthermore, while the range of the number of RBs in the first bandwidth is determined by the terminal's reporting, the specific location information of the first bandwidth can be configured and determined by the network-side equipment. For example, the starting RB of the first bandwidth can be configured by the network-side equipment. Specifically, this can include the network-side equipment configuring the position of the starting point of the first bandwidth relative to a specific RB configuration reference point of the CSI-RS, or the network-side equipment configuring the absolute frequency point position of the starting point of the first bandwidth, or using this RB configuration reference point of a group of CSI-RS with the same RB configuration reference point position as the starting point of the first bandwidth.

[0136] It should be noted that the specific RB configuration reference point location of the CSI-RS is an absolute frequency point configured for the neighboring cell's CSI-RS to determine RB 0 in order to perform Layer 1 mobility measurement based on CSI-RS of the neighboring cell. Based on the RB configuration reference point location, combined with information such as the starting RB identifier, the number of RBs, and the subcarrier spacing configured by the network-side equipment, the terminal can infer the specific bandwidth location of the CSI-RS.

[0137] In some implementations, when the Layer 1 mobility measurement based on CSI-RS is performed in the first cell and the measurement result meets the first requirement, the RB configuration reference point location of the CSI-RS configured in the first cell is the same. This facilitates further configuration of the starting point location of the first bandwidth by the network-side equipment.

[0138] As an optional implementation, the CSI-RS-based Layer 1 mobility measurement includes:

[0139] The CSI-RS is truncated based on the first bandwidth, and Layer 1 mobility measurement is performed based on the truncated CSI-RS.

[0140] The above-mentioned interception of the CSI-RS based on the first bandwidth can be to measure only the resources within the first bandwidth, for example: Figure 4 As shown, only resources within the first bandwidth are measured.

[0141] Specifically, when the terminal performs Layer 1 mobility measurement based on CSI-RS, it can intercept the RE of CSI-RS according to the first bandwidth and complete the measurement.

[0142] Since the CSI-RS is truncated according to the first bandwidth, after the truncation operation is completed, the terminal can send all frequency domain data within that bandwidth into the baseband to perform cell search and synchronization based on multiple FFT windows, thereby improving the terminal's measurement performance. Furthermore, even when the first bandwidth is much smaller than the active BWP bandwidth, the implementation overhead of multiple FFT windows remains within the terminal's acceptable range, thus providing good coverage for scenarios where the reception timing difference is greater than the CP. Additionally, the first bandwidth may not even overlap with the active BWP at all, thus providing good coverage for inter-frequency measurement scenarios based on gaps.

[0143] In some implementations, the frequency domain resource configuration of the CSI-RS of the first cell covers at least the first bandwidth, which allows for better measurement based on the first bandwidth.

[0144] As an optional implementation, if the terminal does not support the first capability but supports the second capability, the terminal supports Layer 1 mobility measurement based on SSB in the first cell, and the terminal supports reporting the measurement results of Layer 1 mobility measurement based on SSB.

[0145] In this embodiment, it is possible to perform Layer 1 mobility measurement based on SSB in the first cell when the first capability is not supported but the second capability is supported, and the terminal supports reporting the measurement results of Layer 1 mobility measurement based on SSB. In the second cell, Layer 1 mobility measurement based on CSI-RS can be performed to improve the measurement performance of the terminal.

[0146] In some implementations, when the reporting configuration received by the terminal from the network-side device includes both SSB-based reporting and CSI-RS-based reporting, the method further includes:

[0147] When the measurement resource configuration includes both SSB resources and CSI-RS resources, the terminal reports the measurement results of Layer 1 mobility measurement based on SSB; or,

[0148] The terminal does not expect or consider the same measurement resource configuration to include both SSB resources and CSI-RS resources, and the terminal only reports the measurement results of SSB-based Layer 1 mobility measurements according to the reporting configuration associated with SSB resources.

[0149] In this implementation, the measurement results of layer 1 mobility measurement based on SSB can be reported when the terminal supports layer 1 event triggers the reporting.

[0150] Since the measurement resource configuration includes both SSB and CSI-RS resources, the terminal reports the measurement results of Layer 1 mobility measurement based on SSB. This enables the reporting of Layer 1 measurement results even when the first capability is not supported, thereby improving the measurement performance of the terminal.

[0151] The terminal does not consider the same measurement resource configuration to include SSB resources and CSI-RS resources. This means that the terminal does not consider the same measurement resource configuration configured by the network-side equipment to include SSB resources and CSI-RS resources.

[0152] Since the terminal only reports the measurement results of SSB-based Layer 1 mobility measurement according to the reporting configuration associated with the SSB resources, this can save reporting resource overhead.

[0153] As an optional implementation, if the terminal does not support the first capability but supports the second capability, the terminal supports Layer 3 mobility measurement based on CSI-RS in the first cell, and the terminal supports reporting the measurement results of Layer 3 mobility measurement based on CSI-RS.

[0154] In this embodiment, since the first capability is not supported, Layer 3 mobility measurement based on CSI-RS is supported in the first cell, and the terminal supports reporting the measurement results of Layer 3 mobility measurement based on CSI-RS, the measurement performance of the terminal can be improved.

[0155] As an optional implementation, the capability reporting operation further includes:

[0156] The terminal reports third indication information, which is used to indicate whether a third capability is supported. The third capability includes:

[0157] Layer 3 mobility measurements based on CSI-RS in the first cell.

[0158] The aforementioned third instruction information and the aforementioned first instruction information or second instruction information may be reported through the same or different messages.

[0159] Because it supports Layer 3 mobility measurement based on CSI-RS in the first cell, the measurement performance of the terminal can be improved.

[0160] In some implementations, when reporting the aforementioned third indication information, the width of the CSI-RS supported by the terminal can also be reported, specifically the width of the CSI-RS corresponding to the third capability.

[0161] As an optional implementation, the frequency domain resources occupied by the CSI-RS of the first cell include:

[0162] The frequency domain resources occupied by the SSB associated with the CSI-RS.

[0163] The frequency domain resources occupied by the CSI-RS of the first cell mentioned above include the frequency domain resources occupied by the SSB associated with the CSI-RS. The frequency domain resources occupied by the CSI-RS of the first cell may overlap with the frequency domain resources occupied by the SSB associated with the CSI-RS.

[0164] In this implementation, since the frequency domain resources occupied by the CSI-RS of the first cell include the frequency domain resources occupied by the SSB associated with the CSI-RS, the terminal can reuse the relevant resources of the SSB when performing measurements, thereby reducing the complexity of the terminal.

[0165] As an optional implementation, if the terminal supports the first capability, the method further includes:

[0166] If the terminal does not support SSB-based Layer 1 measurement, the terminal performs SSB-based Layer 3 measurement in the first cell to obtain time-frequency synchronization information, and performs CSI-RS-based Layer 1 mobility measurement in the first cell based on the time-frequency synchronization information.

[0167] In this implementation, while supporting the first capability, it is possible to obtain time and frequency synchronization information through SSB-based layer 3 measurement, even if SSB-based layer 1 measurement is not supported, so that the terminal measurement can be more flexible.

[0168] It should be noted that in some implementations, the aforementioned time-frequency synchronization information may be obtained in advance, meaning that synchronization is not required when performing Layer 1 mobility measurements based on CSI-RS.

[0169] In this embodiment, the terminal performs a capability reporting operation, which includes reporting first indication information. The first indication information indicates whether a first capability is supported. The first capability includes: performing Layer 1 mobility measurement based on Channel State Information Reference Signal (CSI-RS) in a first cell. The frequency domain resources occupied by the CSI-RS in the first cell include frequency domain resources within a first bandwidth, and the first cell also satisfies at least one of the following: the inter-cell reception timing difference corresponding to the first cell is greater than the Cyclic Prefix (CP); the frequency domain resources occupied by the CSI-RS in the first cell include frequency domain resources outside the Active Bandwidth (BWP) of the serving cell of the terminal. Thus, since the first capability includes performing Layer 1 mobility measurement based on CSI-RS in the first cell, Layer 1 mobility measurement based on CSI-RS is supported in the communication system. If some or all terminals support Layer 1 mobility measurement based on CSI-RS, it is beneficial to improve the communication performance of the communication system.

[0170] Please see Figure 5 , Figure 5 This is a flowchart of a capability information receiving method provided in an embodiment of this application, such as... Figure 5 As shown, it includes the following steps:

[0171] Step 501: The network-side device receives first indication information reported by the terminal. The first indication information is used to indicate whether a first capability is supported. The first capability includes: performing Layer 1 mobility measurement based on Channel State Information Reference Signal (CSI-RS) in a first cell; wherein the frequency domain resources occupied by the CSI-RS of the first cell include frequency domain resources within a first bandwidth, and the first cell also satisfies at least one of the following:

[0172] The reception timing difference between the cells corresponding to the first cell is greater than the cyclic prefix (CP).

[0173] The frequency domain resources occupied by the CSI-RS of the first cell include the frequency domain resources other than the active bandwidth portion (BWP) of the serving cell of the terminal.

[0174] Optionally, the first capability includes:

[0175] When the serving cell of the terminal belongs to the first frequency band combination, it supports performing Layer 1 mobility measurement based on CSI-RS in the first cell.

[0176] Optionally, the first cell belongs to the first frequency band combination.

[0177] Optionally, the method further includes:

[0178] The network-side device receives a second indication information reported by the terminal. The second indication information is used to indicate whether a second capability is supported. The second capability includes: performing Layer 1 mobility measurement based on Channel State Information Reference Signal (CSI-RS) in a second cell; wherein the reception timing difference between the cells corresponding to the second cell is less than or equal to the CP, and the frequency domain resources occupied by the CSI-RS of the second cell include the frequency domain resources within the active BWP of the serving cell of the terminal.

[0179] Optionally, the parameters of the first bandwidth are determined by the configuration sent by the network-side device to the terminal.

[0180] Optionally, the first bandwidth is the frequency domain resource occupied by the synchronization signal block SSB associated with the CSI-RS.

[0181] Optionally, the first indication information is further used to indicate the range of values ​​for the number of resource blocks (RBs) of the first bandwidth supported by the terminal.

[0182] Optionally, the method further includes:

[0183] The network-side device receives third indication information reported by the terminal. This third indication information indicates whether a third capability is supported, and the third capability includes:

[0184] Layer 3 mobility measurements based on CSI-RS in the first cell.

[0185] Optionally, the frequency domain resources occupied by the CSI-RS of the first cell include:

[0186] The frequency domain resources occupied by the SSB associated with the CSI-RS.

[0187] It should be noted that this embodiment is as a comparison with... Figure 2 The implementation methods of the network-side devices shown in the embodiments can be found in the following examples. Figure 2 To avoid repetition, the relevant descriptions of the embodiments shown will not be repeated in this embodiment.

[0188] The method provided in this application is illustrated below through an example:

[0189] Example 1:

[0190] The terminal reports the first indication information to indicate whether it supports the first capability, which includes:

[0191] Layer 1 measurements based on CSI-RS can be performed in the first cell that meets the first condition, and the measurement results are guaranteed to meet the first requirement.

[0192] The first requirement includes at least the following: the measurement accuracy error of RSRP is less than 9dB under a signal-to-noise ratio (Es / IoT) of -3dB.

[0193] If the terminal does not support the first capability, it can also support Layer 1 measurements based on CSI-RS by supporting the second capability. If the terminal supports the second capability, as long as the second cells within the second cell set meet the second condition, CSI-RS measurements within the second cell set can be performed, and the measurement results will be guaranteed to meet the first requirement.

[0194] It should be noted that the reporting of both the first and second capabilities mentioned above can be done on a per-bandwidth-combination basis. This bandwidth combination can be understood as the bandwidth combination of the CA. There are two possible implementation methods:

[0195] Type 1: This bandwidth combination only restricts the serving cell of the terminal to be within the bandwidth combination of CA, without restricting neighboring cells; that is, as long as the serving cell is within the bandwidth combination of CA, if the terminal reports that the corresponding capability is supported, the terminal can perform CSI-RS Layer 1 mobility measurement on neighboring cells of any frequency band.

[0196] Type 2: This bandwidth combination limits the terminal's serving cell and neighboring cells to be within the CA bandwidth combination; that is, when the serving cell is within the CA bandwidth combination, if the terminal reports that the corresponding capability is supported, the terminal can perform CSI-RS Layer 1 mobility measurement on neighboring cells within the CA band.

[0197] The first condition above includes at least one of the following:

[0198] The first receiving timing difference between the measurement cells is greater than the CP and at least covers the first bandwidth;

[0199] The CSI-RS corresponding to the first cell is outside the active BWP of all serving cells and covers at least the first bandwidth.

[0200] The second condition above includes at least two of the following:

[0201] The first receiving timing difference in the measurement interval is less than or equal to the CP.

[0202] The CSI-RS corresponding to the second cell is within the active BWP of all serving cells.

[0203] It should be noted that the first reception timing difference mentioned here refers to the inter-cell reception timing difference determined based on SSB measurements. These SSB measurements include both intra-frequency and inter-frequency measurements, including L1 and / or L3 measurements. For multiple cells on the same frequency, the first reception timing difference is the timing difference between the serving cell and neighboring cells; for multiple cells on different frequencies, the first reception timing difference is the maximum value of the timing differences between any two cells with the same SSB frequency received by the terminal.

[0204] It should be noted that, as mentioned here, "outside the activated BWP" means that at least one RB or one RE of the corresponding reference signal is outside the BWP. "Inside the activated BWP" means that all RBs, i.e., all REs, of the corresponding reference signal are inside the BWP.

[0205] It should be noted that the first bandwidth mentioned here can be the assumed measurement bandwidth (BWP) of the terminal when performing CSI-RS-based mobility measurements. Based on this assumed BWP bandwidth, the terminal can perform CSI-RS RE interception for CSI values ​​exceeding the BWP bandwidth and complete the measurement. The first bandwidth can be an assumed channel bandwidth, an assumed BWP bandwidth, or the RB bandwidth occupied by a reference signal in the frequency domain.

[0206] It should be noted that the term "covering the first bandwidth" mentioned here has two possible interpretations:

[0207] Explanation 1: The CSI-RS has at least X RBs in the first bandwidth, where X is a positive integer greater than or equal to 1.

[0208] Explanation 2: All REs of the CSI-RS are within the first bandwidth.

[0209] Based on this design, the terminal can intercept CSI-RS data exceeding the first bandwidth and then perform RRM measurements. This way, even if the multiple CSI-RS configured by the network may not achieve complete RB alignment, the network can still assign these CSI-RS to the terminal, allowing the terminal to perform the interception operation and complete the measurement itself. After the interception operation, the terminal can send all frequency domain data within this bandwidth to the baseband to perform cell search and synchronization based on multiple FFT windows. Because the first bandwidth can be much smaller than the active BWP bandwidth, the implementation overhead of multiple FFT windows remains within the terminal's acceptable range, thus providing good coverage for scenarios where RTD > CP. Furthermore, because the first bandwidth can even completely avoid overlap with the active BWP, it can effectively cover inter-frequency measurement scenarios based on gaps.

[0210] In one alternative implementation, the first bandwidth is the bandwidth occupied by the SSB associated with the CSI-RS in the frequency domain. That is, the CSI-RS needs to cover at least the bandwidth of the SSB associated with it in the synchronization relationship.

[0211] Specifically, the synchronization relationship mentioned here can be determined based on a quasi-co-location (QCL) relationship, meaning that the network will be configured with a QCL relationship between the SSB and CSI-RS. In particular, this QCL relationship is a QCL-C relationship.

[0212] If the network does not configure a QCL relationship between the CSI-RS to be measured and the corresponding SSB, the terminal will determine any SSB that has the same PCI as the CSI-RS and overlaps in the frequency domain as the SSB that has a synchronization relationship with the CSI-RS.

[0213] Based on this design, the terminal can determine the 20 RBs corresponding to the SSB as the first bandwidth, and then intercept the CSI-RS. In this way, the terminal only needs to design a multi-FFT cell search module with the same bandwidth as the SSB. In addition to the SSB, the CSI-RS signal can also be sent to this cell search module. Since the 20 RB bandwidth is very small, the complexity of the module can be greatly reduced.

[0214] In another optional implementation, in addition to the first bandwidth, the terminal also determines a second bandwidth. That is, the first bandwidth is the bandwidth of the SSB, and in the terminal capability reporting, the terminal only reports capabilities if the first condition is met. However, the bandwidth for which the terminal actually performs multi-FFT processing is a second bandwidth that covers the first bandwidth. The width of the second bandwidth is a protocol-limited value, such as 48 RB. In this case, it may also include: the CSI-RS configured on the network-side device not only covers the first bandwidth, but its width also needs to be greater than the width of the second bandwidth.

[0215] Based on this design, the terminal can determine a channel bandwidth of no less than the second bandwidth according to the frequency point where the target cell's SSB is located, and perform CSI-RS measurements. Since the bandwidth that the network needs to guarantee coverage is decoupled from the bandwidth that the terminal actually needs to use, more flexibility is provided for both network deployment and terminal implementation.

[0216] In one optional implementation, the first bandwidth is determined by a group of N RBs, including the RBs occupied in the frequency domain by the SSBs that are synchronized with the CSI-RS. N can be 48, or determined based on the terminal's reporting capabilities. Specifically, N can also be a channel bandwidth supported by the terminal, i.e., BWP bandwidth. In this way, the CSI-RS and SSBs still have a frequency domain overlap, but in this case, the specific location of the first bandwidth can be determined based on network configuration. For example, the terminal determines the center frequency of the corresponding first bandwidth based on the center frequency of the associated SSB. Another example is that the terminal determines the RB0 of the first bandwidth based on the RB0 of the associated SSB. Yet another example is that the terminal determines the starting RB position of the first bandwidth based on the common RBs configured for the CSI-RS, according to an integer multiple of N (i.e., the RB0 of the first bandwidth is RBN, RB2N, or RB3N, etc.) or other relationships based on N.

[0217] Alternatively, in another implementation, the terminal may choose not to support the first capability and only support the second capability. In this case, for... Figure 3 In the scenarios covered by the first capability, the terminal supports Layer 1 measurements based on SSB and reports the measurement results based on SSB. At this time, the terminal can still cover Layer 1 measurements in scenarios where the receiving timing difference is greater than CP, but it cannot perform measurements in advance for more refined network beams.

[0218] It is important to note that, for Figure 3 In scenarios involving the first capability, the terminal can also choose to support the first capability, namely Layer 1 measurement based on CSI-RS, but not Layer 1 measurement based on SSB. Such terminals can exist at least in FR1. In this way, the terminal can obtain coarse synchronization timing based on Layer 3 measurement of SSB, and obtain more detailed network beam measurement results based on CSI-RS, as well as adjust the Doppler frequency offset.

[0219] Considering the L1 measurement, for Figure 3 In the scenarios involved in Layer 1 capability, the terminal can selectively support either SSB-based or CSI-RS-based reporting. Therefore, in some neighboring cell measurement results, the terminal may only obtain either SSB or CSI-RS data. For this situation, there are two potential implementation options for Layer 1 event-triggered reporting:

[0220] Option 1, if the measurement resource configuration associated with a certain reporting configuration contains both SSB resources and CSI-RS resources, then for... Figure 3In the neighboring cells involved in the first capability, the terminal will not report the measurement results based on CSI-RS at Layer 1, but only the measurement results based on SSB; or the terminal will not report the measurement results based on SSB at L1, but only the measurement results based on CSI-RS.

[0221] Option 2: The terminal does not assume that the network will associate a certain reported configuration with both SSB measurement resources and CSI-RS-based measurement resources.

[0222] Considering the Layer 1 reporting triggered by the event, it is necessary to ensure that the measurement signal types of the serving cell and neighboring cells are completely consistent, i.e., both are CSI-RS or both are SSBs. Since the measurement reference signal of the serving cell is generally obtained based on an active or indicated (i.e., in use) Transmission Configuration Indicator (TCI), when a QCL source exists for the CSI-RS of this TCI, the terminal can determine that the QCL source SSB is the SSB used to trigger the SSB event. When a QCL source does not exist for this TCI, the terminal can determine a certain SSB with the same PCI as this TCI as the SSB of the serving cell to determine whether the event has been triggered. Specifically, a certain SSB can be the SSB with the highest RSRP, the lowest RSRP, or any SSB.

[0223] Alternatively, in another implementation, the terminal may choose not to support the first capability and only support the second capability. In this case, for... Figure 3 In the scenarios covered by the first capability, the terminal does not support either SSB-based Layer 1 measurement or CSI-RS-based Layer 1 measurement, but instead supports CSI-RS-based Layer 3 measurement, triggering LTM based on the CSI-RS L3 measurement results. Considering that in existing technologies, CSI-RS Layer 3 measurement only supports the scenarios covered by the first capability and scenarios outside of BWP that are based on gaps and have a reception timing difference less than CP, the terminal needs to report a third capability, indicating that in addition to the scenarios already supported by the existing technology, it also supports scenarios with a reception timing difference greater than CP.

[0224] Optionally, when the terminal reports the third capability, it can also report a CSI-RS measurement bandwidth that supports receiving timing differences greater than the CP, and the value can be an integer number of RBs such as 24RB or 48RB.

[0225] Optionally, in scenarios where a terminal reports a third capability, in addition to ensuring that the receiving timing difference is greater than the CP, the CSI-RS resources must also cover the SSB resources. Only when both of these conditions are met can a terminal reporting a third capability support the RTD>CP scenario.

[0226] Based on this design, terminal capabilities can be further introduced on top of CSI-RS Layer 3 measurements to support measurement in various scenarios and improve the terminal's mobility experience.

[0227] In this embodiment, even if the Layer 1 CSI-RS of multiple cells configured by the network-side equipment may not achieve complete RB alignment (a typical scenario in existing networks with multiple BWPs), the network can still configure these CSI-RS to the terminal, allowing the terminal to perform interception operations and complete measurements based on the first bandwidth. After completing the interception operation, the terminal can send all frequency domain data within this bandwidth to the baseband to perform cell search and synchronization based on multiple FFT windows. Because the first bandwidth can be much smaller than the bandwidth of the active BWP, the implementation overhead of multiple FFT windows is still within the acceptable range for the terminal, thus providing good coverage for scenarios where RTD>CP. Because the first bandwidth can even have no overlap with the active BWP, it can also provide good coverage for inter-frequency measurement scenarios based on gaps.
