[0040] QCL indication / assumptions for downlink transmission

[0041] To improve reception performance when receiving signals, terminal devices can leverage the characteristics of the transmission environment to refine their reception algorithms. For example, terminal devices can utilize the statistical characteristics of the channel to optimize the design and parameters of the channel estimator. In some communication systems (such as NR systems), the characteristics of the transmission environment can be represented by QCL information (QCL-Info).

[0042] When different transmission and receiving points (TRPs), panels, and beams are used for downlink data transmission, the characteristics of the transmission environment may change. Therefore, in some communication systems (such as NR systems), when downlink control channels or downlink data channels need to be transmitted, network devices can indicate the corresponding QCL information to the terminal devices through the transmission configuration indicator (TCI) status.

[0043] A TCI status can contain the following configuration information: TCI status identifier (identity, ID), QCL information 1, and QCL information 2 (optional). The TCI status ID can be used to identify a TCI status.

[0044] QCL information can include the following: QCL type configuration and QCL reference signal configuration. The QCL type configuration can be one of QCL-Type A, QCL-Type B, QCL-Type C, or QCL-Type D. The QCL reference signal configuration can include the cell identifier (cell ID) of the reference signal, the bandwidth part (BWP), and the identifier of the reference signal (such as the channel state information-reference signal (CSI-RS) resource identifier or the synchronization signal / physical broadcast channel block (PBCH) SSB index).

[0045] If both QCL information 1 and QCL information 2 are configured, then at least one of the QCL information in QCL information 1 and QCL information 2 must have a QCL type of one of QCL-Type A, QCL-Type B, or QCL-Type C, and the other QCL information must have a QCL type of QCL-Type D.

[0046] In some implementations, the definitions of different QCL type configurations are as follows:

[0047] QCL Type A: {Doppler shift, Doppler spread, average delay, delay spread};

[0048] QCL-TypeB: {Doppler offset, Doppler extension};

[0049] QCL Type C: {Doppler offset, average delay};

[0050] QCL Type D (QCL-TypeD): {Spatial Receive Parameters}.

[0051] In NR systems, network devices can indicate the corresponding TCI state for downlink signals or downlink channels. If the network device configures the QCL reference signal of the target downlink channel or target downlink signal as SSB or CSI-RS through the TCI state, and the QCL type is configured as QCL-TypeA, QCL-TypeB, or QCL-TypeC, then the terminal device can assume that the target downlink signal and the large-scale parameters of the SSB or CSI-RS are the same. The specific content of the large-scale parameters can be determined based on the QCL type configuration.

[0052] Similarly, if a network device configures the QCL reference signal for the target downlink channel or downlink signal as SSB or CSI-RS via TCI state, and the QCL type is configured as QCL-TypeD, then the terminal device can receive the target downlink signal using the same receive beam (i.e., the same spatial Rx parameter) as the one used to receive the SSB or CSI-RS. Typically, on the network device side, the target downlink channel (or target downlink signal) and its referenced SSB or CSI-RS are transmitted by the same TRP / panel / beam. If the TRP / panel / beam used to transmit the two downlink signals (or downlink channels) are different, then different TCI states are usually configured for the two downlink signals (or downlink channels).

[0053] For downlink control channels, the TCI status of the control resource set (CORESET) corresponding to the downlink control channel can be indicated by radio resource control (RRC) signaling or RRC signaling plus medium access control (MAC) signaling.

[0054] For a downlink data channel (i.e., a physical downlink shared channel (PDSCH)), the set of available TCI states for the downlink data channel can be indicated by RRC signaling, and some of the TCI states can be activated by MAC layer signaling. Finally, one or two TCI states can be indicated from the activated TCI states through the TCI state indication field in the downlink control information (DCI) for the downlink data channel scheduled by the DCI.

[0055] In some implementations, RRC signaling can configure up to M TCI states for the terminal through PDSCH configuration (PDSCH-Config), where the value of M is determined by the capabilities of the terminal device, M is a positive integer, and the maximum value of M can be 128.

[0056] In some implementations, the MAC control element (CE) activates up to eight TCI state groups to map to the 3-bit TCI information field in the DCI. Each TCI state group activated by the MAC CE can contain one or two TCI states. If the higher-layer parameters configure the DCI to include a TCI indicator field, DCI format 1_1 can indicate a TCI state group from the MAC-activated TCI state groups. If the higher-layer parameters configure the DCI not to include a TCI indicator field or if the data is scheduled via DCI format 1_0, the DCI will not contain a TCI state indicator field.

[0057] Introduction to Near Field Communication

[0058] Near-field communication (NFC) can be understood as a communication system whose communication process satisfies near-field characteristics. In future 6G networks, larger antenna apertures and higher frequency bands will be adopted (e.g., centimeter waves, millimeter waves, and terahertz waves), making near-field characteristics more pronounced in communication systems. Furthermore, the introduction of emerging technologies such as reconfigurable intelligence surfaces (RIS), multiple-input multiple-output (MIMO), movable antennas, and cell-free networks will also make near-field characteristics more prevalent in future wireless networks. For example, the near-field effect of massive MIMO can be understood as the introduction of massive MIMO not only increasing system capacity and coverage but also significantly shortening the near-field region.

[0059] In near-field communication, due to the altered propagation characteristics of electromagnetic waves, they can no longer be simply approximated as plane waves but must be considered as spherical waves. From the perspective of space resource utilization, although traditional wireless communication systems have achieved significant success in the exploration and utilization of far-field space resources, further exploration and application of space resources in near-field communication is expected to bring new physical space dimensions to wireless communication systems.

[0060] Currently, the division between the near-field and far-field regions can be achieved using the following method: Assuming the antenna aperture is represented by D and the wavelength by λ, the range r corresponding to the far field satisfies... The wavefront is approximately a plane wave; the near-field corresponding range r satisfies... The wavefront is a spherical wave.

[0061] Near-field beamforming

[0062] Beamforming is a technique that uses an antenna array to direct wireless signals to a specific receiver. It improves the quality, capacity, and reliability of wireless communication by generating constructive useful signals or destructive interference at the receiver through signals with different amplitudes and phases transmitted from different antennas. However, as shown in Figure 2, in traditional far-field communication, because the electromagnetic wavefront is planar, beamforming (or beam focusing) technology can only control signal propagation in one dimension: angle (direction). Unlike far-field communication, in near-field communication, the propagation characteristics of spherical waves can be utilized, allowing beamforming technology to focus signal energy at a specific location in space, achieving control over signal propagation in both angular and distance dimensions.

[0063] In traditional wireless communication systems, beamforming can only control signal propagation in one dimension. However, with the development of wireless communication systems, beamforming can control signal propagation in multiple dimensions, making traditional beam reporting methods no longer applicable.

[0064] For example, traditional wireless communication systems are heavily reliant on far-field characteristics. When the antenna array is large, signal propagation characteristics change significantly, and near-field characteristics provide a more accurate description of the channel environment compared to far-field characteristics. In far-field communication systems, because electromagnetic waves can be considered plane waves, beamforming (or beam focusing) can only control signal propagation in one dimension: angle. Unlike far-field systems, near-field systems have electromagnetic waves that are closer to spherical waves. Based on the propagation characteristics of spherical waves, beamforming technology can focus signal energy at a specific location in space, achieving control over signal propagation in both angle and distance dimensions. However, traditional beam reporting methods are designed for scenarios where beam selection is limited to the angle dimension; therefore, traditional beam reporting methods are no longer applicable.

[0065] To address the aforementioned issues, this application provides a wireless communication method in which a terminal device can indicate (or report) multiple interrelated reference signal resources to a network device, enabling the network device to select a beam (hereinafter referred to as the "first beam"). These multiple reference signal resources can correspond to multiple different dimensions of the control signal propagation. Compared to traditional solutions where the terminal device indicates reference signal resources corresponding to one dimension (i.e., angle) for beam selection, this method helps improve the accuracy of beam selection.

[0066] In some implementations, multiple reference signal resources correspond to multiple dimensions of control signal propagation. This can be replaced by the fact that the beam information associated with the multiple reference signal resources belongs to different information domains, or that the beam information associated with the multiple reference signal resources belongs to different dimensions.

[0067] In some implementations, the aforementioned multiple different information fields may include a distance field and / or an angle field. Of course, in the embodiments of this application, the multiple information fields may include other information fields.

[0068] In some implementations, multiple reference signal resources may include multiple CSI-RS resources or multiple SSB resources. This application does not limit this to specific implementations.

[0069] In some implementations, multiple reference signal resources correspond to multiple different dimensions of the control signal propagation described above. This can be replaced by multiple reference signal resources being used to select the first beam (including a transmit beam or a receive beam), or in other words, multiple reference signal resources jointly selecting the first beam. The first beam can, for example, be a beam that satisfies near-field characteristics as described above, also known as a near-field beam.

[0070] In some implementations, the multiple reference signal resources may include a first reference signal resource and a second reference signal resource. The first and second reference signal resources are used to select a first beam, or in other words, the first and second reference signal resources jointly select the first beam. The first beam may, for example, be a beam that satisfies near-field characteristics as described above, also known as a near-field beam.

[0071] In some implementations, the first reference signal resource can be associated with beam information in the angle domain, and the second reference signal resource can be associated with beam information in the range domain. Of course, in the embodiments of this application, the first reference signal resource can be associated with beam information in the range domain, and the second reference signal resource can be associated with beam information in the angle domain.

[0072] For example, referring to Figure 3, assume the distance between terminal device 120 and network device 110 is distance 1. The communication angle between terminal device 120 and network device 110 is angle 1. In this case, the first reference signal resource can be associated with the beam information at angle 1, and the second reference signal resource can be associated with the beam information at distance 1. Accordingly, the beam indicated by the first reference signal resource and the second reference signal resource is beam 1.

[0073] It should be noted that, in the embodiments of this application, the reference signal resource associated with the beam information in the angle domain can be understood as being used to select a suitable beam in the angle domain, or in other words, the reference signal resource is used to determine the beam information in the angle domain. Correspondingly, the reference signal resource associated with the beam information in the range domain can be understood as being used to select a suitable beam from the range domain, or in other words, the reference signal resource is used to determine the beam information in the range domain.

[0074] In some implementations, the information for configuring the first reference signal resource and the second reference signal resource occupies the same time domain unit. That is, configuring the first reference signal resource and configuring the second reference signal resource can be performed simultaneously, which helps to reduce the latency of configuring the first reference signal resource and the second reference signal resource for the terminal device. Of course, in the embodiments of this application, the information for configuring the first reference signal resource and the second reference signal resource occupies different time domain units.

[0075] For example, the time domain unit where the information for configuring the first reference signal resource is located can precede the time domain unit where the information for configuring the second reference signal resource is located. That is, the first reference signal resource can be configured before the second reference signal resource. In this case, the terminal device can perform measurements based on the first reference signal resource configured earlier and instruct the network device. Then, the network device can configure the second reference signal resource associated with the first reference signal resource for the terminal device based on the first reference signal resource indicated by the terminal device, which helps to reduce the overhead of configuring the second reference signal resource.

[0076] For example, the time domain unit where the information for configuring the first reference signal resource is located can be later than the time domain unit where the information for configuring the second reference signal resource is located. That is, the first reference signal resource can be configured later than the second reference signal resource. In this case, the terminal device can perform measurements based on the first configured second reference signal resource and instruct the network device. Then, the network device can configure the first reference signal resource associated with the second reference signal resource for the terminal device based on the second reference signal resource indicated by the terminal device, which helps to reduce the overhead of configuring the first reference signal resource.

[0077] In this application embodiment, the aforementioned time-domain unit is not limited. In some implementations, the time-domain unit may include one of the following: time slot, subframe, symbol, or frame. Of course, in this application embodiment, the aforementioned time-domain unit may also be a new time-domain unit introduced in future communication systems.

[0078] The first reference signal resource and the second reference signal resource of the embodiments of this application have been introduced above. The first reference signal resource set and the second reference signal resource set of the embodiments of this application are described below.

[0079] In some implementations, the first reference signal resource belongs to a first set of reference signal resources, and the second reference signal resource belongs to a second set of reference signal resources, wherein the reference signal resources in the first set of reference signal resources are associated with the reference signal resources in the second set of reference signal resources.

[0080] In some implementations, reference signal resources in the first set of reference signal resources can be associated with the same information domain. Correspondingly, reference signal resources in the second set of reference signal resources can be associated with the same information domain. Furthermore, the information domains associated with the reference signal resources in the first set and the second set are different. For example, the information domain associated with the reference signal resources in the first set may be an angle domain, while the information domain associated with the reference signal resources in the second set may be a distance domain. Another example is that the information domain associated with the reference signal resources in the first set may be a distance domain, while the information domain associated with the reference signal resources in the second set may be an angle domain.

[0081] In this application embodiment, the implementation method of the above association is not limited. In some implementations, a first reference signal resource in a first reference signal resource set is associated with a subset of reference signal resources in a second reference signal resource set, and the subset of reference signal resources includes the second reference signal resource. In this application embodiment, the number of reference signal resources included in the subset of reference signal resources is not limited. For example, the subset of reference signal resources may include one or more reference signal resources.

[0082] Taking the example of associating beam information in the angle domain with a first set of reference signal resources and beam information in the range domain with a second set of reference signal resources, a first reference signal resource in the first set of reference signal resources can be associated with a subset of reference signal resources, and the subset of reference signal resources contains multiple reference signal resources. In this case, it can be understood that the first reference signal resource is associated with beam information at a specific angle, and correspondingly, the subset of reference signal resources is associated with beam information at multiple distances corresponding to that angle. That is to say, the first reference signal resource, and the subset of reference signal resources associated with it, are used to indicate the beam information corresponding to different distances at a certain angle.

[0083] Taking the example of associating a first set of reference signal resources with beam information in the range domain and a second set of reference signal resources with beam information in the angle domain, a first reference signal resource in the first set of reference signal resources can be associated with a subset of reference signal resources, and the subset of reference signal resources contains multiple sets of reference resource information. In this case, it can be understood that the first reference signal resource is associated with beam information at a specific distance, and correspondingly, the subset of reference signal resources is associated with beam information at multiple angles corresponding to that distance. That is to say, the first reference signal resource, and the subset of reference signal resources associated with it, are used to indicate the beam information corresponding to different angles at a certain distance.

[0084] For example, continuing to refer to Figure 3, assume that the distance between terminal device 120 and network device 110 includes distances 1 to 3. The communication angle between terminal device 120 and network device 110 is angle 1. Accordingly, the first reference signal resource set may include first reference signal resources associated with beam information at angle 1, and the reference signal resource subset of the second reference signal resource set may include second reference signal resources associated with beam information at distance 1, second reference signal resources associated with beam information at distance 2, and second reference signal resources associated with beam information at distance 3. In this case, the first reference signal resource is associated with the reference signal resource subset, and correspondingly, the beams indicated by the first reference signal resource and the associated reference signal resource subset can be focused at the same angle but at different distances.

[0085] In some other implementations, the first reference signal resource in the first reference signal resource set is associated with the second reference signal resource set.

[0086] For example, referring to Figure 4, assume that the first set of reference signal resources includes reference signal resources 1 to 4, and the second set of reference signal resources includes reference signal resources 5 to 8. Reference signal resource 1 is associated with the second set of reference signal resources; that is, reference signal resource 1 is associated with reference signal resources 5 to 8.

[0087] The first reference signal resource set and the second reference signal resource set of the embodiments of this application have been introduced above. The following describes the measurement scheme based on the first reference signal resource set and the second reference signal resource set in the embodiments of this application.

[0088] In some implementations, the above method further includes: the terminal device measuring a first set of reference signal resources, selecting a first reference signal resource, wherein the measurement result of the first reference signal resource is higher than or equal to the measurement results of other reference signal resources, and the other reference signal resources are reference signal resources in the first set of reference signal resources other than the first reference signal resource; the terminal device selecting a reference signal resource to be measured from a second set of reference signal resources based on the first reference signal resource, wherein the first reference signal resource is associated with the reference signal resource to be measured, and the reference signal resource to be measured includes the second reference signal resource.

[0089] In the embodiments of this application, the measurement results are not limited. In some implementations, the measurement results may include one or more of the following: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), and signal to interference plus noise ratio (SINR).

[0090] In this embodiment of the application, the terminal device can first determine the first reference signal resource with better measurement results from the first reference signal resource set, and then select the reference signal resource to be measured associated with the first reference signal resource from the second reference signal resource set based on the first reference signal. This helps to reduce the number of reference signal resources measured by the terminal device in the second reference signal resource set, thereby improving the efficiency of measuring reference signal resources.

[0091] The reference signal resources and reference signal resource sets in the embodiments of this application have been introduced above. The following section, with reference to Figure 5, takes multiple reference signal resources, including the first reference signal resource and the second reference signal resource, as an example to introduce the wireless communication method of the embodiments of this application. This method can be applied to the beam reporting process.

[0092] Figure 5 is a schematic flowchart of a wireless communication method according to an embodiment of this application. The method shown in Figure 5 includes step S510.

[0093] In step S510, the terminal device sends the first information to the network device.

[0094] In some implementations, the first information is used to indicate the first reference signal resource and the second reference signal resource, or in other words, the first information carries an indication of the first reference signal resource and an indication of the second reference signal resource.

[0095] In some implementations, the first reference signal resource is associated with the second reference signal resource. For example, the first reference signal resource and the second reference signal resource are used to indicate the first beam. For a description of the first reference signal and the second reference signal, please refer to the above.

[0096] In some implementations, the first information is used to indicate k first reference signal resources and / or q second reference signal resources, where k and q are positive integers.

[0097] In this embodiment, the values ​​of k and q are not limited. In some implementations, the value of k can be the same as the value of q. In other implementations, the value of k can be different from the value of q. For example, the value of k can be less than the value of q. Or, for example, the value of k can be greater than the value of q.

[0098] In some implementations, the first information is used to indicate the measurement result corresponding to each of the k first reference signal resources, and / or the first information is used to indicate the measurement result corresponding to each of the q second reference signal resources.

[0099] For example, the first information can be used to indicate k first reference signal resources, q second reference signal resources, and the measurement result corresponding to each of the q second reference signal resources. The measurement result corresponding to each of the q second reference signal resources helps the network device perform beam selection. Alternatively, the first information can indicate the measurement result corresponding to the q second reference signal resources instead of the measurement result corresponding to the k first reference signal resources, which helps reduce the overhead of transmitting the first information.

[0100] It should be noted that the above-mentioned scheme regarding the content carried by the first information can be applied to scenarios where the terminal device first measures the reference signal resources in the first reference signal resource set and then measures the reference signal resources in the second reference signal resource set, wherein k first reference signal resources belong to the first reference signal resource set and q second reference signal resources belong to the second reference signal resource set.

[0101] For example, a first set of reference signal resources includes multiple first reference signal resources, and a second set of reference signal resources includes multiple second reference signal resources. First information can be used to indicate k first reference signal resources in the first set of reference signal resources, q second reference signal resources in the second set of reference signal resources, the measurement results corresponding to each of the k first reference signal resources, and the measurement results corresponding to each of the q second reference signal resources. The measurement results corresponding to each of the k first reference signal resources and the q second reference signal resources help the network device perform beam selection.

[0102] In some implementations, the first information carries the first reference measurement result, as well as the difference between the measurement result corresponding to each of the k first reference signal resources and the first reference measurement result, which helps to reduce the amount of information carried in the first information.

[0103] In this embodiment, the first reference measurement result is not limited. In some implementations, the first reference measurement result can be the maximum value among the measurement results corresponding to k first reference signal resources. In other implementations, the first reference measurement result can be the minimum value among the measurement results corresponding to k first reference signal resources. In still other implementations, the first reference measurement result can be any value among the measurement results corresponding to k first reference signal resources. Of course, in this embodiment, the first reference measurement result can also be an additional measurement result that is different from all the measurement results corresponding to k first reference signal resources.

[0104] In some implementations, the first information carries the second reference measurement result, as well as the difference between the measurement result corresponding to each of the q second reference signal resources and the second reference measurement result.

[0105] In this embodiment, the second reference measurement result is not limited. In some implementations, the second reference measurement result can be the maximum value among the measurement results corresponding to q second reference signal resources. In other implementations, the second reference measurement result can be the minimum value among the measurement results corresponding to q second reference signal resources. In still other implementations, the second reference measurement result can be any value among the measurement results corresponding to q second reference signal resources. Of course, in this embodiment, the second reference measurement result can also be an additional measurement result that is different from all the measurement results corresponding to q second reference signal resources.

[0106] It should be noted that the first reference measurement result and the second reference measurement result may be the same or different, and this application embodiment does not limit this. The following describes the content carried by the first information in the embodiments of this application with reference to Examples 1 and 2.

[0107] Example 1: Suppose that the measurement result corresponding to first reference signal resource 1 among k first reference signal resources is the maximum value among the measurement results corresponding to k first reference signal resources, then the first reference measurement result is the measurement result corresponding to first reference signal resource 1. Similarly, the measurement result corresponding to second reference signal resource 1 among q second reference signal resources is the maximum value among the measurement results corresponding to q second reference signal resources, then the second reference measurement result is the measurement result corresponding to second reference signal resource 1.

[0108] Accordingly, the first information is used to indicate k first reference signal resources, q second reference signal resources, a first reference measurement result, (k-1) differences, a second reference measurement result, and (q-1) differences. Specifically, the (k-1) differences indicate the differences between the measurement results of the (k-1) first reference signal resources (excluding first reference signal resource 1) and the second reference measurement results. Similarly, the (q-1) differences indicate the differences between the measurement results of the (q-1) second reference signal resources (excluding second reference signal resource 1) and the second reference measurement results.

[0109] Example 2: Suppose that the measurement result corresponding to second reference signal resource 1 among q second reference signal resources is the maximum value among the measurement results corresponding to the q second reference signal resources, then the second reference measurement result is the measurement result corresponding to second reference signal resource 1. In this case, the first information is used to indicate k first reference signal resources, q second reference signal resources, the second reference measurement result, and (q-1) differences. The (q-1) differences are used to indicate the differences between the measurement results of the (q-1) second reference signal resources other than second reference signal resource 1 and the second reference measurement result.

[0110] It should be noted that the scheme described in Example 2 can be applied to scenarios where the terminal device first measures the reference signal resources in the first reference signal resource set and then measures the reference signal resources in the second reference signal resource set, where k first reference signal resources belong to the first reference signal resource set and q second reference signal resources belong to the second reference signal resource set.

[0111] The content carried in the first information in the embodiments of this application has been introduced above. The transmission method of the first information is described below.

[0112] In some implementations, the first information may be carried in a first measurement report, which carries the k first reference signal resources indicated by the first information and / or the measurement results corresponding to the k first reference signal resources.

[0113] In some implementations, the first information may be carried in a second measurement report, which carries the q second reference signal resources indicated by the first information and / or the measurement results corresponding to the q second reference signal resources.

[0114] In this embodiment, the first measurement report can be used in combination with the second measurement report. For example, the first and second measurement reports can be used together to select a first beam. That is, step S510 includes: the terminal device sending the first measurement report and the second measurement report to the network device. Of course, in this embodiment, the first and second measurement reports can be used independently.

[0115] For example, assuming that the measurement result corresponding to first reference signal resource 1 among k first reference signal resources is the maximum value among the measurement results corresponding to k first reference signal resources, then the first reference measurement result is the measurement result corresponding to first reference signal resource 1. Similarly, if the measurement result corresponding to second reference signal resource 1 among q second reference signal resources is the maximum value among the measurement results corresponding to q second reference signal resources, then the second reference measurement result is the measurement result corresponding to second reference signal resource 1.

[0116] Accordingly, the first measurement report carries k first reference signal resources indicated by the first information, a first reference measurement result, and (k-1) differences. The second measurement report carries q second reference signal resources indicated by the first information, a second reference measurement result, and (q-1) differences. The (k-1) differences indicate the differences between the measurement results of the (k-1) first reference signal resources (excluding first reference signal resource 1) and the first reference measurement result. The (q-1) differences indicate the differences between the measurement results of the (q-1) second reference signal resources (excluding second reference signal resource 1) and the second reference measurement result.

[0117] For example, suppose that the measurement result corresponding to second reference signal resource 1 among q second reference signal resources is the maximum value among the measurement results corresponding to q second reference signal resources, then the second reference measurement result is the measurement result corresponding to second reference signal resource 1. Accordingly, the first measurement report carries the k first reference signal resources indicated by the first information. The second measurement report carries the q second reference signal resources indicated by the first information, the second reference measurement result, and (q-1) differences. Among them, the (q-1) differences are used to indicate the differences between the measurement results of the (q-1) second reference signal resources other than second reference signal resource 1 and the second reference measurement result.

[0118] As described above, the first measurement report and the second measurement report can be used to select the first beam. Therefore, the first measurement report and the second measurement report can be correlated so that the network device can determine the beam selection based on the correlated first measurement report and the second measurement report.

[0119] In the embodiments of this application, the manner in which the first measurement report and the second measurement report are correlated is not limited. In some implementations, the first measurement report may carry indication information of the second reference signal resource, wherein the indication information of the second reference signal resource may include one or more of the following: indication information of the second reference signal resource set (e.g., the identifier of the second reference signal resource set), indication information of a subset in the second reference signal resource set (e.g., the identifier of the subset), and the identifier of the second reference signal resource.

[0120] In some other implementations, the second measurement report may carry indication information of the first reference signal resource, wherein the indication information of the first reference signal resource may include one or more of the following: indication information of the first reference signal resource set (e.g., the identifier of the first reference signal resource set), and the identifier of the first reference signal resource.

[0121] In other implementations, the first measurement report may carry indication information of the second measurement report, or the second measurement report may carry indication information of the first measurement report. This indication information may be, for example, an index or identifier. Of course, in the embodiments of this application, the first and second measurement reports may carry the same identifier or index to indicate that the first and second measurement reports are associated.

[0122] In some implementations, the first information can be carried in a third measurement report, wherein the third measurement report carries the k first reference signal resources indicated by the first information and the q second reference signal resources indicated by the first information. Alternatively, step S510 above includes: the terminal device sending a third measurement report to the network device, wherein the first information in the third measurement report is used to indicate the first reference signal resources and the second reference signal resources.

[0123] In some implementations, the third measurement report may also carry the measurement results corresponding to k first reference signal resources and / or q second reference signal resources.

[0124] For example, when a terminal device sends a third measurement report to a network device, the third measurement report carries a first reference signal resource, a second reference signal resource, the measurement results corresponding to the first reference signal resource, and the measurement results corresponding to the second reference signal resource, as shown in Table 1.

[0125] Table 1

[0126] It should be noted that the terminal device can send multiple third measurement reports to the network device, and the content shown in Table 1 can be the content of one of the multiple third measurement reports.

[0127] For example, when a terminal device sends a third measurement report to a network device, the third measurement report carries the first reference signal resource, the second reference signal resource, and the measurement result corresponding to the second reference signal resource. In this embodiment, the third measurement report may not carry the measurement result corresponding to the first reference signal resource, which helps to reduce the overhead of transmitting the third measurement report.

[0128] The transmission method of the first information in the embodiments of this application has been introduced above. The following section introduces the relevant schemes for configuring the transmission method of the first information for the terminal device by the network device.

[0129] In some implementations, the above method further includes: the network device sending first configuration information to the terminal device, the first configuration information being used to configure the transmission of first information through one or more measurement reports.

[0130] In some implementations, the first configuration information can be carried in RRC signaling.

[0131] In some implementations, the first configuration information includes channel state information (CSI) reporting configuration (CSI-ReportConfig), and the number of CSI reporting configurations carried in the first configuration information is used to indicate the first information to be transmitted through one or more measurement reports.

[0132] In some implementations, if the number of CSI reported configurations is 1, the first information is transmitted through a single measurement report; and / or if the number of CSI reported configurations is multiple (or more than two CSI reported configurations), the first information is transmitted through multiple measurement reports.

[0133] In other implementations, the first configuration information includes CSI reporting configuration, where a first field indicates that the first information is transmitted via one or more measurement reports. Of course, in this embodiment, the transmission of the first information via one or more measurement reports can be predefined, such as through protocol predefinition. For example, the protocol can predefine that the terminal device transmits the first information via only one measurement report. Alternatively, the protocol can predefine that the terminal device transmits the first information via multiple measurement reports.

[0134] It should be noted that the aforementioned transmission of the first information through multiple measurement reports can be understood as the transmission of the first information through a first measurement report and a second measurement report. The first measurement report carries the first reference signal resource indicated by the first information, and / or the measurement results corresponding to the first reference signal resource; the second measurement report carries the second reference signal resource indicated by the first information, and / or the measurement results corresponding to the second reference signal resource. For related details, please refer to the above text.

[0135] In some implementations, the method further includes: the network device sending second configuration information to the terminal device, the second configuration information being used to configure the number of first reference signal resources and the number of second reference signal resources indicated in the first information. Alternatively, the second configuration information is used to configure the number of first reference signal resources indicated and the number of second reference signal resources indicated in the first information.

[0136] In the embodiments of this application, the above-mentioned quantity is not limited. In some implementations, the above-mentioned quantity can be a positive integer, for example, the quantity may include 1, 2, 3, 4.

[0137] In traditional wireless communication systems, beamforming can only control signal propagation in one dimension. However, with the development of wireless communication systems, beamforming can control signal propagation in multiple dimensions, making traditional beam pointing methods no longer applicable.

[0138] For example, traditional wireless communication systems are heavily reliant on far-field characteristics. When the antenna array becomes large, signal propagation characteristics change significantly, and near-field characteristics provide a more accurate description of the channel environment compared to far-field characteristics. In far-field communication systems, because electromagnetic waves can be considered plane waves, beamforming (or beam focusing) can only control signal propagation in one dimension: angle. Unlike far-field systems, near-field systems have electromagnetic waves that are closer to spherical waves. Based on the propagation characteristics of spherical waves, beamforming technology can focus signal energy at a specific location in space, achieving control over signal propagation in both angular and distance dimensions. However, traditional beam pointing methods are designed for this scenario of indicating the beam in only the angular dimension; therefore, traditional beam pointing methods are no longer applicable.

[0139] To address the aforementioned issues, another embodiment of this application provides a wireless communication method in which a network device can indicate multiple interrelated reference signal resources to a terminal device, enabling the terminal device to determine the beam indicated by the network device (hereinafter referred to as the "first beam"). The multiple reference signal resources can correspond to multiple different dimensions of the control signal propagation. Compared to traditional solutions, where the network device indicates the beam to the terminal device by indicating reference signal resources corresponding to one dimension (i.e., angle), this method helps improve the accuracy of beam indication.

[0140] It should be noted that the multiple reference signal resources in the embodiments of this application can be referred to in the above description, and will not be repeated here for the sake of brevity. The following description, with reference to Figure 6, takes multiple reference signal resources, including a first reference signal resource and a second reference signal resource, as an example.

[0141] Figure 6 is a schematic flowchart of a wireless communication method according to another embodiment of this application. The method shown in Figure 6 includes step S610.

[0142] In step S610, the network device sends second information to the terminal device, the second information being used to indicate the first reference signal resource and the second reference signal resource.

[0143] In some implementations, the first reference signal resource and the second reference signal resource are used to determine the first beam. For details regarding the first reference signal resource, the second reference signal resource, and the first beam, please refer to the above text.

[0144] In some implementations, the second information is used to determine QCL information, which is associated with a first reference signal resource and / or with a second reference signal resource. In other words, the QCL type of the QCL information is associated with the first reference signal resource and / or with the second reference signal resource.

[0145] In some implementations, the QCL type of the QCL information can include one of the following: QCL-Type A, QCL-Type B, QCL-Type C, or QCL-Type D. For related information, please refer to the above text.

[0146] For example, the QCL type of the QCL information is QCL-Type D, which is associated with a first reference signal and a second reference signal. That is, the spatial reception parameters corresponding to QCL type D can be characterized by the two reference signals mentioned above. Specifically, the first reference signal is associated with spatial reception parameters in the angle domain, and the second reference signal is associated with spatial reception parameters in the range domain. Alternatively, the first reference signal is associated with spatial reception parameters in the range domain, and the second reference signal is associated with spatial reception parameters in the range domain.

[0147] In the embodiments of this application, the transmission method of the second information is not limited. In some implementations, the second information may be carried in one or more of the following: RRC signaling, MAC CE, and DCI.

[0148] In some implementations, the second information is used to indicate the first TCI state, which is associated with QCL information. That is, the first TCI state is associated with a first reference signal resource, and / or the first TCI state is associated with a second reference signal resource.

[0149] For example, the first TCI status information may include one or more of the following: the TCI status ID of the first TCI status, used to identify the first TCI status; QCL information 1; QCL information 2. Each QCL information may further include at least one of the following: QCL type configuration; the cell ID of the reference signal; the BWP ID of the reference signal; reference signal information 1; reference signal information 2; wherein reference signal information 1 and reference signal information 2 may be CSI-RS resource IDs or SSB indexes.

[0150] This application does not limit the first TCI state described above in its embodiments. In some implementations, the first TCI state can be a unified TCI state. The unified TCI state can include three modes: a joint TCI state, applicable to both uplink and downlink channels and signals; a downlink TCI state (DL TCI state), applicable only to downlink channels and signals; and an uplink TCI state (UL TCI state), applicable only to uplink channels and signals. The DL TCI state and the UL TCI state can be referred to as separate DL / UL TCI states.

[0151] In some implementations, the downlink channels (e.g., partial PDCCH, PDSCH) and signals (e.g., aperiodic CSI-RS) use the same downlink transmit beam, which can be indicated using DL TCI status or combined TCI status.

[0152] In some implementations, the uplink channel (PUCCH, PUSCH) and the signal (e.g., SRS) can use the same uplink transmit beam, wherein the uplink transmit beam can be indicated using UL TCI status or combined TCI status.

[0153] In some implementations, the first TCI state can be single-carrier indicated, meaning the carrier transmitting the first TCI state is the same as the carrier using the first TCI state. In other implementations, the first TCI state can be cross-carrier indicated, meaning the carrier transmitting the first TCI state is different from the carrier using the first TCI state. In still other implementations, the first TCI state can be multi-carrier indicated, and the carrier using the first TCI state can include multiple carriers.

[0154] In some implementations, the second information is used to indicate a TCI state group, the QCL information associated with the TCI state group is associated with a first reference signal resource, and the QCL information associated with the TCI state in the TCI state group is associated with multiple second reference signal resources.

[0155] In some implementations, different second reference signal resources among multiple second reference signal resources are associated with different beam information.

[0156] For example, if the first reference signal is associated with beam information in the angle domain and the second reference signal is associated with beam information in the range domain, then a TCI state group can be associated with beam information in the angle domain, and different TCI states in the TCI state group can each be associated with beam information in the range domain. That is to say, a TCI state group can be associated with beam information with the same angle but different distances.

[0157] For example, if the first reference signal is associated with beam information in the range domain and the second reference signal is associated with beam information in the angle domain, then a TCI state group can be associated with beam information in the range domain, and different TCI states in the TCI state group can each be associated with beam information in the angle domain. That is to say, a TCI state group can be associated with beam information with the same range but different angles.

[0158] In some scenarios, the terminal device can autonomously determine the TCI state associated with the first beam information (i.e., the first TCI state described above) based on the first beam information communicated with the network device. The first beam information includes angle-domain beam information associated with a first reference signal resource and / or range-domain beam information associated with a second reference signal resource. Alternatively, the first beam information includes angle-domain beam information associated with a second reference signal resource and / or range-domain beam information associated with the first reference signal resource.

[0159] In other words, the above method further includes: the terminal device selecting a TCI state associated with the first beam information from the TCI state group based on the first beam information and the beam information associated with different TCI states in the TCI state group, wherein the beam information includes angle-domain beam information associated with the first reference signal resource and / or range-domain beam information associated with the second reference signal resource. Alternatively, the beam information includes angle-domain beam information associated with the second reference signal resource and / or range-domain beam information associated with the first reference signal resource.

[0160] In other scenarios, the first TCI state used by the terminal device may be indicated by the network device. That is, the above method also includes: the network device sending third information to the terminal device, the third information being used to indicate the TCI state from the TCI state group.

[0161] It should be noted that, in the embodiments of this application, the methods shown in Figure 5 and Figure 6 can be used individually. Alternatively, the methods shown in Figure 5 and Figure 6 can be used in combination. In this case, the terminal device can use the scheme shown in Figure 5 to report the beam, and correspondingly, the network device can select a suitable beam (i.e., the first beam) based on the beam reported by the terminal device, and provide beam indication to the terminal device through the method shown in Figure 6.

[0162] The method embodiments of this application have been described in detail above with reference to Figures 1 to 6.
