Description

Communication methods, systems and related equipment

[0001] This application claims priority to Chinese Patent Application No. 202411586649.6, filed on November 11, 2024, entitled "Communication Method, System and Related Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, system and related equipment. Background Technology

[0003] Layer 1 signal-to-interference-plus-noise ratio (L1-SINR) is a parameter that measures the quality of communication signals in a communication system. Typically, network equipment (such as base stations) can configure reference signal (RS) resources for channel and interference measurements for user equipment (UEs) located within its signal coverage area. This allows the UE to measure, calculate, and report L1-SINR based on the configured RS resources.

[0004] In practical applications, network devices can indicate a currently used beam to the UE by sending an indicated TCI state. Furthermore, the network device can configure a set of alternative beams (new beams) for the UE. Based on this, the UE can measure, calculate, and report L1-SINR for the current beam and the new beams separately. However, since the measurement and reporting of L1-SINR can be implemented based on various resource settings, and the RS resource settings of the current beam and the new beams are independent of each other, there may be situations where the RS resource settings of the current beam and the new beams are different. This will lead to different standards for calculating L1-SINR, thus making it impossible to directly compare the L1-SINR results. Summary of the Invention

[0005] This application provides a communication method, system, and related equipment, the purpose of which is to obtain L1-SINR with a unified measurement standard for both current beams and new beams, so that the L1-SINR corresponding to the two beams can be compared.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] Firstly, this application provides a communication method applied to a network device. The method includes: First, the network device can send configuration information, for example, the network device sends configuration information to a user equipment (UE). This configuration information can be used to configure a reference signal (RS) resource set. The RS resource set is used for channel measurement and interference measurement. The RS resource set includes RS resources corresponding to a first beam and RS resources corresponding to a second beam. The RS resources corresponding to the first beam are all resources in the RS resource set except for the RS resources corresponding to the second beam. The RS resources corresponding to the first beam are used to determine the Layer 1 Signal-to-Interference-plus-Noise Ratio (L1-SINR) of the first beam, and the RS resources corresponding to the second beam are used to determine the L1-SINR of the second beam. Then, the network device can send indication information for the second beam, for example, the network device sends indication information for the second beam to the UE. This indication information is used to indicate the RS resources corresponding to the second beam. For example, the indication information for the second beam is an indicated TCI state, and the RS resource associated with this indicated TCI state is the RS resource corresponding to the current beam. In addition, the first and second beams are used to compare their quality and determine whether a preset condition is met based on the comparison result. This preset condition is used in the UE-initiated / event-driven beam reporting (UEI / ED beam reporting) process. Accordingly, the UE can specifically determine the L1-SINR of the first beam based on the RS resources corresponding to the first beam in the received configuration information, and determine the L1-SINR of the second beam based on the RS resources corresponding to the second beam indicated by the received indication information of the second beam. Thus, the network device can receive the L1-SINR of the first beam and / or the L1-SINR of the second beam, such as when the network device receives the L1-SINR of the first beam and / or the L1-SINR of the second beam reported by the UE.

[0008] Therefore, since the RS resources corresponding to the first beam and the second beam both belong to the RS resource set corresponding to the aforementioned configuration information, the L1-SINR of the first beam and the L1-SINR of the second beam are determined through RS resources in the same RS resource set. Thus, the L1-SINR of the first beam and the L1-SINR of the second beam can be determined using consistent resource settings. In this way, the network device can horizontally compare the L1-SINR results of the two beams. Furthermore, if the network device subsequently receives the L1-SINRs corresponding to the two beams respectively, it can understand the channel conditions corresponding to these two beams.

[0009] In one possible implementation, the RS resources corresponding to the first beam and the RS resources corresponding to the second beam are of the same type. This ensures that the RS resources used by the two beams to determine the L1-SINR are of the same type, facilitating the obtaining of a standardized L1-SINR and enabling comparison of the L1-SINRs corresponding to the two beams.

[0010] In one possible implementation, the RS resources corresponding to the first beam and the RS resources corresponding to the second beam both include CMR, or the RS resources corresponding to the first beam and the RS resources corresponding to the second beam both include CMR and IMR.

[0011] In one possible implementation, the aforementioned RS resource set may further include a first RS resource set, which includes IMRs. The first RS resource set is used to determine the L1-SINR of the first beam and the L1-SINR of the second beam. In this way, the network device can use the IMRs in the first RS resource set included in the RS resource set as dedicated IMR resources for both beams, facilitating interference measurements of the two beams.

[0012] In one possible implementation, if the CMR in the RS resource corresponding to the second beam does not belong to the RS resource set, then the IMR in the RS resource corresponding to the second beam and the IMR in the RS resource corresponding to the first beam both belong to the first RS resource set. Therefore, if the CMR in the RS resource corresponding to the second beam does not come from the aforementioned RS resource set, then a dedicated IMR configured in the RS resource set can be used as a dedicated IMR resource for both beams, facilitating interference measurement of the two beams.

[0013] In one possible implementation, the first beam is a candidate beam provided by the network device, i.e., a new beam, and the second beam is the currently used beam, i.e., a current beam. In this way, this solution can determine the L1-SINR for the new beam and the current beam separately, thereby unifying the measurement standard of L1-SINR for both and allowing for comparison between them.

[0014] In one possible implementation, the network device can also send signaling, for example, to the UE, indicating the need to update the RS resources corresponding to the first beam or the second beam. In this way, the network device can update the RS resources in the aforementioned RS resource set via signaling.

[0015] In one possible implementation, the RS resources corresponding to the first beam include CMR and IMR, and a mapping relationship exists between the CMR and IMR. Accordingly, during the signaling process of the network device, the network device can send a first signaling message, such as sending a first signaling message to the UE. This first signaling message can be used to indicate the update of the CMR and IMR, or it can be used to indicate the update of the CMR and the mapping relationship, or it can be used to indicate the update of the CMR, IMR, and the mapping relationship. In this way, during the process of the network device updating the CMR in the RS resources via signaling, the mapping relationship between the IMR and CMR can also be updated synchronously via signaling, or the CMR can be updated synchronously via signaling.

[0016] In one possible implementation, the first signaling may include a first field; when the first field takes a first value, for example, when the first field is 0, the first signaling is used to indicate support for updating the CMR; when the first field takes a second value, for example, when the first field is 1, the first signaling is used to indicate support for updating both the CMR and the IMR. Therefore, the first field can indicate whether updating the IMR is supported in the first signaling.

[0017] In one possible implementation, the RS resource corresponding to the first beam includes multiple CMRs, and the multiple CMRs include the first CMR. The first signaling also includes a second field. When the value of the first field is a second value and the value of the second field is a third value, for example, when the first field is 1 and the second field is 0, the first signaling is used to indicate updating the first CMR but not updating the IMR corresponding to the first CMR. When the value of the first field is a second value and the value of the second field is a fourth value, for example, when the first field is 1 and the second field is 1, the first signaling is used to indicate updating the first CMR and the IMR corresponding to the first CMR. Therefore, through the first and second fields, the first signaling can indicate whether to update the IMR corresponding to the first CMR, if updating the IMR is supported.

[0018] In one possible implementation, the number of IMRs corresponding to the first CMR is multiple. The first signaling also includes a third field and a fourth field. The fourth field carries the identifier of the first IMR among the multiple IMRs. When the first field is a second value, the second field is a fourth value, and the third field is a fifth value, for example, when the first field is 1, the second field is 1, and the third field is 0, the first signaling is used to indicate that the first IMR is the last IMR among the multiple IMRs. When the first field is a second value, the second field is a fourth value, and the third field is a sixth value, for example, when the first field is 1, the second field is 1, and the third field is 1, the first signaling is used to indicate that the first IMR is not the last IMR among the multiple IMRs. Therefore, by using the first, second, third, and fourth fields, the first signaling can indicate whether the first IMR is the last IMR among the multiple IMRs corresponding to the first CMR when updating the first IMR, thereby determining the number of multiple IMRs and the mapping relationship between the first CMR and the corresponding multiple IMRs.

[0019] In one possible implementation, the RS resources corresponding to the first beam include CMR and IMR, and a mapping relationship exists between CMR and IMR. Accordingly, during the signaling process of the network device, the network device can send a second signaling message, such as sending a second signaling message to the UE, and this second signaling message is used to instruct the updating of the IMR, or to instruct the updating of the IMR and the mapping relationship. In this way, during the process of the network device updating the IMR in the RS resources via signaling, the mapping relationship between the IMR and CMR can also be updated synchronously via signaling, without updating the CMR.

[0020] In one possible implementation, the second signaling includes a fifth field carrying an identifier of the second IMR. The second signaling is used to indicate that the second IMR should be updated to the RS resource corresponding to the first beam. Thus, the fifth field allows the second signaling to indicate the update of the second IMR, enabling network devices to update the IMR via signaling.

[0021] In one possible implementation, there are multiple IMRs, and the fifth field carries the identifiers of multiple IMRs. The second signaling is used to instruct the mapping relationship to be updated based on the order of the identifiers of the multiple IMRs in the fifth field. In this way, the mapping relationship between the multiple IMRs and their corresponding CMRs in the fifth field can be indicated in the second signaling through the fifth field, so that the network device can update the mapping relationship through signaling.

[0022] Secondly, this application provides a communication method applied to a user equipment (UE). The method includes: the UE receiving configuration information, such as configuration information sent by a network device, the configuration information being used to configure an RS resource set, the RS resource set being usable for channel measurement or interference measurement, and the RS resource set including RS resources corresponding to a first beam and RS resources corresponding to a second beam, the RS resources corresponding to the first beam being resources in the RS resource set excluding the RS resources corresponding to the second beam; then, the UE may receive indication information for the second beam, for example, the UE further receiving indication information for the second beam sent by the network device, the indication information being... The RS resources corresponding to the second beam are used to indicate the first beam and the second beam. The quality of the first beam and the second beam are compared and the results are used to determine whether the preset conditions are met. The preset conditions are used by the UE to initiate / event-triggered beam reporting procedures. Thus, the UE can determine the Layer 1 Signal-to-Interference-plus-Noise Ratio (L1-SINR) of the first beam based on the RS resources corresponding to the first beam, and determine the L1-SINR of the second beam based on the RS resources corresponding to the second beam, and send the L1-SINR of the first beam and / or the L1-SINR of the second beam. For example, the UE sends the L1-SINR of the first beam and / or the L1-SINR of the second beam to the network device.

[0023] In one possible implementation, the RS resources corresponding to the first beam and the RS resources corresponding to the second beam are of the same type.

[0024] In one possible implementation, the RS resources corresponding to the first beam and the RS resources corresponding to the second beam both include channel measurement resources (CMR), or the RS resources corresponding to the first beam and the RS resources corresponding to the second beam both include CMR and interference measurement resources (IMR).

[0025] In one possible implementation, the RS resource set further includes a first RS resource set, which includes an IMR, and the first RS resource set is used to determine the L1-SINR of the first beam and the L1-SINR of the second beam.

[0026] In one possible implementation, if the CMR in the RS resource corresponding to the second beam does not belong to the RS resource set, the IMR in the RS resource corresponding to the second beam and the IMR in the RS resource corresponding to the first beam both belong to the first RS resource set.

[0027] In one possible implementation, the first beam is an alternative beam provided by the network device, and the second beam is the beam currently in use.

[0028] In one possible implementation, the UE may further receive signaling for instructing the updating of RS resources corresponding to the first beam or the second beam.

[0029] In one possible implementation, the RS resources corresponding to the first beam include CMR and IMR, and there is a mapping relationship between CMR and IMR. Accordingly, when the UE receives signaling, it may specifically receive a first signaling message, which is used to indicate the update of CMR and IMR, or the first signaling message is used to indicate the update of CMR and mapping relationship, or the first signaling message is used to indicate the update of CMR, IMR and mapping relationship.

[0030] In one possible implementation, the first signaling includes a first field; when the first field takes a first value, the first signaling is used to indicate support for updating the CMR; when the first field takes a second value, the first signaling is used to indicate support for updating both the CMR and the IMR.

[0031] In one possible implementation, the RS resources corresponding to the first beam include multiple CMRs and multiple IMRs. The multiple CMRs include the first CMR, and the multiple IMRs include the IMR corresponding to the first CMR. The first signaling also includes a second field. When the value of the first field is the second value and the value of the second field is the third value, the first signaling is used to indicate updating the first CMR but not updating the IMR corresponding to the first CMR. When the value of the first field is the second value and the value of the second field is the fourth value, the first signaling is used to indicate updating the first CMR and the IMR corresponding to the first CMR.

[0032] In one possible implementation, the number of IMRs corresponding to the first CMR is multiple, and the first signaling further includes a third field and a fourth field. The fourth field carries the identifier of the first IMR among the multiple IMRs corresponding to the first CMR. When the value of the first field is the second value, the value of the second field is the fourth value, and the value of the third field is the fifth value, the first signaling is used to indicate that the first IMR is the last IMR among the multiple IMRs corresponding to the first CMR. When the value of the first field is the second value, the value of the second field is the fourth value, and the value of the third field is the sixth value, the first signaling is used to indicate that the first IMR is not the last IMR among the multiple IMRs corresponding to the first CMR.

[0033] In one possible implementation, the RS resources corresponding to the first beam include CMR and IMR, and there is a mapping relationship between CMR and IMR. Accordingly, when the UE receives signaling, it may specifically receive second signaling, which is used to indicate updating the IMR, or the second signaling is used to indicate updating the IMR and the mapping relationship.

[0034] In one possible implementation, the second signaling includes a fifth field carrying an identifier of the second IMR, and the second signaling is used to indicate that the second IMR is updated to the RS resource corresponding to the first beam.

[0035] In one possible implementation, there are multiple IMRs, and the fifth field carries the identifiers of the multiple IMRs. The second signaling is used to indicate the updating of the mapping relationship based on the order of the identifiers of the multiple IMRs in the fifth field.

[0036] Thirdly, this application provides a network device including a transceiver and a processor; wherein the transceiver is used to perform the receiving operation and the transmitting operation in the method described in the first aspect or any embodiment of the first aspect; and the processor is used to perform other operations in the method described in the first aspect or any embodiment of the first aspect besides the receiving operation and the transmitting operation.

[0047] .

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, "one or more" refers to one, two, or more; "and / or" describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0049] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0050] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0051] In the UEI / ED beam reporting process, in addition to supporting Layer 1 Reference Signal Received Power (L1-RSRP) as a measurement metric, L1-SINR can also be supported as a measurement metric to measure the communication quality of the communication system. Generally, network devices can configure RS resources for channel measurement and interference measurement for UEs located within their signal coverage area. For example, RS resources for channel measurement may include synchronization signal / physical broadcast channel block (SSB) or Non-Zero Power Channel State Information-Reference Signal (NZP CSI-RS), while RS resources for interference measurement may include Channel State Information-Interference Measurement (CSI-IM) or single-port NZP CSI-RS. Thus, the UE can measure, calculate, and report L1-SINR based on the configured RS resources.

[0052] Furthermore, the current L1-SINR measurement and reporting process can mainly include the following three configuration methods:

[0053] In the first approach, when a network device is configured with a resource setting that is implemented through a higher-level parameter resourcesForChannelMeasurement, the resource setting can be used for channel measurement, or it can be used for both channel measurement and interference measurement.

[0054] In the second method, when the network device is configured with two resource settings, the first resource setting is implemented through the higher-layer parameter resourcesForChannelMeasurement, and the second resource setting is implemented through the higher-layer parameter csi-IM-ResourcesForInterference or nzp-CSI-RS-ResourcesForInterference, then the first resource setting can be used for channel measurement, and the second resource setting can be used for interference measurement based on CSI-IM or NZP CSI-RS.

[0055] In the third method, when the network device is configured with three resource settings, the first resource setting is implemented through the higher-layer parameter resourcesForChannelMeasurement, the second resource setting is implemented through the higher-layer parameter csi-IM-ResourcesForInterference, and the third resource setting is implemented through the higher-layer parameter nzp-CSI-RS-ResourcesForInterference. In this case, the first resource setting can be used for channel measurement, the second resource setting can be used for CSI-IM based interference measurement, and the third resource setting can be used for NZP CSI-RS based interference measurement.

[0056] Therefore, it can be seen that the measurement and reporting of L1-SINR can be achieved based on a variety of resource settings.

[0057] Furthermore, in some applications, the network device can indicate a current beam to the UE by sending an indicated TCI state. That is, the RS resource corresponding to the current beam is the RS resource associated with the indicated TCI state, and this current beam can be associated with a specific event type. In addition, the network device can also configure new beams for the UE. That is, all RS resources corresponding to the new beams come from a single RS resource set associated with a CSI report configuration set by the network device, and the new beams can be associated with a specific event type.

[0058] Based on this, the UE can measure, calculate, and report L1-SINR for the current beam and new beams separately. However, as mentioned earlier, the measurement and reporting of the current L1-SINR can be implemented based on various resource settings, and the RS resource settings for the current beam and new beams are independent of each other. Therefore, there may be situations where the RS resource settings for the current beam and new beams are different. This will lead to different standards for calculating L1-SINR for the two beams. Therefore, the L1-SINR results for the two beams cannot be directly compared.

[0059] Furthermore, the RS resources associated with the aforementioned indicated TCI state may only include channel measurement resources (CMR) and not the corresponding interference measurement resources (IMR). Therefore, this situation can also lead to inconsistent RS resource settings between the current beam and new beams.

[0060] Therefore, this application provides a communication system, which can be a fifth-generation (5G) communication system, a hybrid architecture of LTE and 5G, a 5G New Radio (5G NR) system, or a new communication system that will emerge in the future development of communication.

[0061] An example of a communication system is shown in Figure 1, which includes network device 1 and UE2.

[0062] In the embodiments provided in this application, network device 1 can be any device located on the network side and having wireless transceiver capabilities, including but not limited to: base stations (gNodeB or gNB) or transmission receiving points / transmission reception points (TRPs) in new radio (NR). Network device 1 can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, or balloon stations, etc. Network device 1 can include one or more co-located or non-co-located transmission reception points (TRPs). Network device 1 can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. Network device 1 can communicate with terminal devices or communicate with terminal devices through relay stations.

[0063] UE2 can communicate with multiple base stations using different technologies. For example, UE2 can communicate with base stations that support LTE networks, base stations that support 5G networks, 3G or 2G networks, or base stations with higher standards such as 6G. It can also establish dual connections with both LTE and 5G base stations.

[0064] In the embodiments provided in this application, UE2 can take various forms, such as a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal device, etc. UE can sometimes also be referred to as terminal device, access terminal device, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, terminal device, wireless communication device, UE agent, or UE device, etc. The terminal can also be a fixed terminal or a mobile terminal.

[0065] The above description uses a communication system including network device 1 and UE2 as an example. In other possible implementations, the communication system may include multiple UEs or multiple network devices. Alternatively, in other possible implementations, network device 1 in the communication system may be replaced with other types of network devices, and this is not limited. For ease of understanding, the following description will still take the interaction between UE2 and network device 1 as an example.

[0066] In the communication system shown in Figure 1, network device 1 can send configuration information to UE2 for configuring a reference signal (RS) resource set. This RS resource set is used for channel measurement and interference measurement, and includes all RS resources corresponding to new beams and RS resources corresponding to the current beam. The RS resources corresponding to new beams are all resources in the RS resource set except for the RS resources of the current beam. Then, network device 1 can send an indicated TCI state to the UE. The RS resources associated with this indicated TCI state are the RS resources corresponding to the current beam. Accordingly, UE2 can subsequently determine the L1-SINR of the new beams based on the RS resources corresponding to the new beams, and determine the L1-SINR of the current beam based on the RS resources corresponding to the current beam. The aforementioned new beams (denoted as new beam RS#1, new beam RS#2, new beam RS#... and new beam RS#N in Figure 1) and the current beam (denoted as the second beam in Figure 1) serve as two types of beams provided by the network device to the UE. The UE can compare the quality of these two beams and determine whether preset conditions are met based on the comparison results. These preset conditions can be used to initiate the UEI / ED beam reporting process, such as the UE determining whether Event-2 is met based on the comparison results. In this way, the network device can receive the L1-SINR of the new beams and / or the L1-SINR of the current beam, for example, the network device receives the L1-SINR of the new beams and / or the L1-SINR of the current beam reported by the UE. Since the RS resources corresponding to the new beams and the RS resources of the current beam both belong to the RS resource set, the L1-SINR of the new beams and the L1-SINR of the current beam are determined using the same resource settings. In this way, the L1-SINR results of the two can be compared horizontally. That is to say, the L1-SINR corresponding to these two beams can be directly compared.

[0067] Furthermore, UE2 can subsequently compare the L1-SINR results corresponding to the two beams to determine if the event triggering conditions are met. For example, UE2 compares whether the L1-SINR values ​​corresponding to the two beams meet the triggering conditions of Event-2, and then determines whether to initiate the beam management process. Initiating the beam management process means that when the triggering conditions of Event-2 are met, UE2 can send a request to network device 1. This request can specifically request resources for sending beam reports. The content of the beam report can include the L1-SINR of the new beams and / or the L1-SINR of the current beam. Based on this, after UE2 obtains the resources for sending beam reports, it can send the beam report to network device 1. Thus, if network device 2 subsequently receives the L1-SINR values ​​corresponding to the two beams, it can understand the channel conditions corresponding to these two beams. Alternatively, the beam management process can also refer to the following: when the triggering condition of Event-2 is met, UE2 can send a notification to network device 1 to send a beam report on the pre-configured resources, and then send a beam report on the pre-configured resources. The content of the beam report includes the L1-SINR of the new beams and / or the L1-SINR of the current beam.

[0068] Referring to Figure 2, a communication method provided by an embodiment of this application is illustrated. The communication method shown in Figure 2 can be applied to the communication system shown in Figure 1, or it can be applied to other possible communication systems. For ease of understanding and explanation, the following description uses the communication system shown in Figure 1 as an example. As shown in Figure 2, the process of this communication method includes the following steps:

[0069] S201: Network device 1 sends configuration information to UE2. The configuration information is used to configure the RS resource set. The RS resource set is used for channel measurement and interference measurement. The RS resource set includes the RS resource corresponding to the first beam and the RS resource corresponding to the second beam. The RS resource corresponding to the first beam is the resource in the RS resource set other than the RS resource corresponding to the second beam.

[0070] In the UEI / ED beam reporting process, network device 1 first provides UE2 with a first beam and a second beam. In practical applications, the first beam mentioned in this embodiment can be referred to as "new beams" (new beams may include one beam or multiple beams), and the second beam can be referred to as "current beam." UE2 can measure the reference signal quality of these two beams, such as measuring the L1-RSRP or L1-SINR of these two beams, and compare the reference signal quality of these two beams to determine whether the comparison result meets a preset condition. Then, if the comparison result meets the preset condition, UE2 can report the measurement result to network device 1. In other words, these preset conditions can be used in the UEI / ED beam reporting process. For example, the preset conditions can include multiple conditions, such as a first condition, a second condition, or a third condition. The first condition could be Event-7 as defined in the standard (Event-7 involves at least one new beam whose reference signal quality is higher than the reference signal quality of the Qth best quality RS resource derived from the activated TCI states plus a threshold; the current beam corresponds to the Qth best quality RS resource derived from the activated TCI states). The second condition could be Event-2 as defined in the standard (Event-2 involves at least one new beam whose reference signal quality is higher than the current beam's quality plus a threshold). The third condition could be Event-1 as defined in the standard (Event-1 involves the current beam's quality being lower than a predefined threshold), and so on. Furthermore, UE2 can perform beam switching when the above preset conditions are met, selecting a beam with better quality to further improve communication quality.

[0071] Furthermore, regarding Event-7, in this embodiment, the RS resources associated with the activated TCI states corresponding to the current beam and the RS resources corresponding to the new beams have the same resource settings, thereby ensuring that the L1-SINR calculation and measurement methods for the new beams and the current beam are consistent. Based on this, at least for Event-7, the RS resources associated with the activated TCI states come from the same RS resource set in a CSI-ReportConfiguration to which the new beams belong, or the RS resources associated with the activated TCI states come from the first RS resource set of a CSI-ReportConfiguration to which the new beams belong.

[0072] Next, in this embodiment, network device 1 can send the aforementioned configuration information to UE2. Since this configuration information can be used to configure the RS resource set, network device 1 can configure the RS resource set corresponding to the configuration information to UE2. As an example, network device 1 can pre-configure the RS resource set in a CSI-ReportConfiguration corresponding to the new beams, and explicitly configure the RS resources corresponding to the new beams therein. Furthermore, since the RS resources corresponding to the new beams included in the RS resource set are used to determine the L1-SINR of the new beams, UE2 can subsequently use the RS resources corresponding to the new beams in the RS resource set to determine the L1-SINR of the new beams.

[0073] Furthermore, the RS resource set configured for UE2 by network device 1 also includes the RS resources corresponding to the current beam. The RS resources corresponding to the aforementioned new beams are the resources in this RS resource set other than the RS resources of the current beam. Accordingly, UE2 can subsequently use the RS resources corresponding to the current beam in the RS resource set to determine the L1-SINR of the current beam.

[0074] It should be noted that, in addition to the RS resource set configured through the above configuration information including the RS resource corresponding to the current beam, the RS resource corresponding to the current beam can also come from other RS ​​resource sets, which are not specifically limited here.

[0075] S202: Network device 1 sends indication information of the second beam to UE2. The indication information of the second beam is used to indicate the RS resource corresponding to the second beam.

[0076] As mentioned earlier, the second beam can be referred to as the current beam. In practical applications, network device 1 can send an indicated TCI state to UE2. This indicated TCI state can indicate the current beam to the UE, and the RS resource corresponding to the current beam is the RS resource associated with the indicated TCI state. It should be noted that the RS resource associated with the indicated TCI state can be a quasi-co-location (QCL) RS resource directly corresponding to the indicated TCI state, or it can be an SSB resource associated with the corresponding QCL RS resource based on the QCLed. The RS resource corresponding to the current beam can be an SSB resource or an NZP CSI-RS resource.

[0077] Therefore, when determining the L1-SINR of the new beams and the current beam, since the RS resources corresponding to both the new beams and the current beam belong to the RS resource set corresponding to the aforementioned configuration information, the L1-SINR of the first beam and the L1-SINR of the second beam are determined using RS resources from the same RS resource set. In other words, the L1-SINR of the first beam and the L1-SINR of the second beam are determined using consistent resource settings. This allows for a horizontal comparison of the L1-SINR results corresponding to the two beams; that is, the L1-SINRs corresponding to these two beams can be directly compared. Furthermore, if network device 2 subsequently receives the L1-SINRs corresponding to the two beams, it can understand the channel conditions corresponding to these two beams.

[0078] Furthermore, in this embodiment, the RS resource set also includes a first RS resource set for interference measurement, which includes IMR, so that the first RS resource set can be used by UE2 to determine the L1-SINR of new beams and current beam respectively.

[0079] As a possible example, regarding the construction process of the first RS resource set described above, network device 1 can pre-configure the first RS resource set in a CSI-ReportConfiguration corresponding to the new beams. For example, a CSI-ReportConfiguration may include a second resource setting (implemented through the higher-layer parameter csi-IM-ResourcesForInterference) and a third resource setting (implemented through the higher-layer parameter nzp-CSI-RS-ResourcesForInterference), where csi-IM-ResourcesForInterference can perform interference measurement based on CSI-IM, and nzp-CSI-RS-ResourcesForInterference can perform interference measurement based on NZP CSI-RS. In this way, network device 1 can define the first n RS resources associated with csi-IM-ResourcesForInterference or nzp-CSI-RS-ResourcesForInterference to construct the first RS resource set.

[0080] Furthermore, as mentioned earlier, besides the RS resource set configured through the above configuration information, which includes the RS resource corresponding to the current beam, the RS resource corresponding to the current beam can also come from other RS ​​resource sets. Therefore, if the CMR in the RS resource corresponding to the current beam does not belong to the aforementioned RS resource set, then the IMR in the RS resource corresponding to the current beam and the IMR in the RS resource corresponding to the new beams can adopt the IMR in the aforementioned first RS resource set. In other words, the IMR in the RS resource corresponding to the current beam and the IMR in the RS resource corresponding to the new beams both belong to the first RS resource set. In this way, even if the CMR in the RS resource corresponding to the current beam does not belong to the aforementioned RS resource set, the RS resources corresponding to the current beam and the new beams can still include IMRs from the same RS resource set. This allows the L1-SINR of the new beams and the L1-SINR of the current beam to be determined through RS resources in the same RS resource set, thus unifying the measurement standards for the L1-SINR of the current beam and the L1-SINR of the new beams.

[0081] Furthermore, a CSI-ReportConfiguration corresponding to the aforementioned new beams may also include a first resource setting (implemented through the higher-layer parameter resourcesForChannelMeasurement), which includes RS resources for performing channel measurements.

[0082] Based on this, in this embodiment, if the resource settings corresponding to the new beams are different from those corresponding to the current beam—that is, if the resource settings of a CSI-ReportConfiguration corresponding to the new beams and the resource settings corresponding to the current beams include different first, second, and third resource settings, respectively—then, in order to unify the L1-SINR measurement standards corresponding to the current beams and the new beams, network device 1 can further constrain the types of resources used by the current beams and the new beams when reporting measurements. Specifically, network device 1 can configure the RS resources corresponding to the new beams and the RS resources corresponding to the current beams to be of the same type. As an example, the RS resources corresponding to the current beams and the new beams both include CMR, or the RS resources corresponding to the current beams and the new beams both include CMR and IMR.

[0083] Furthermore, the `resourcesForChannelMeasurement` objects for both new beams and the current beam can include the number of RS resources corresponding to each beam. Therefore, when UE2 determines the L1-SINR of the current beam and the L1-SINR of the new beams, the number of RS resources used by the new beams and the current beam is the same. As an example, if the number of RS resources included in the `resourcesForChannelMeasurement` objects for the new beams and the current beam is different, then UE2 can use the minimum value of the number of RS resources corresponding to the new beams and the current beam as the number of RS resources used by the new beams and the current beam, respectively.

[0084] S203: UE2 determines the L1-SINR of the first beam based on the RS resources corresponding to the first beam, and determines the L1-SINR of the second beam based on the RS resources corresponding to the second beam.

[0085] As mentioned earlier, the RS resources used to determine the L1-SINR of the current beam are of the same type as those used to determine the L1-SINR of the new beams. Therefore, as an example, when the RS resources corresponding to both the current beam and the new beams include CMR, UE2 can calculate the L1-SINR of the current beam and the L1-SINR of the new beams separately based solely on CMR. When the RS resources corresponding to both the current beam and the new beams include both CMR and IMR, UE2 can calculate the L1-SINR of the current beam and the L1-SINR of the new beams jointly based on both CMR and IMR. For ease of understanding, Table 1 below describes how UE2 determines the L1-SINR.

[0086] Table 1

[0087] As shown in Table 1, IMR can also be divided into NZP-IMR and ZP-IMR. Therefore, when the RS resources corresponding to the current beam and new beams both include CMR and NZP-IMR, UE2 can calculate the L1-SINR of the current beam and the L1-SINR of the new beams based on CMR and NZP-IMR.

[0088] It should be noted that when the RS resources corresponding to both the new beams and the current beam include CMR, ZP-IMR, and NZP-IMR, UE2 can choose at least one of the following methods from Table 1: CMR, CMR, and ZP-IMR, or CMR, NZP, and IMR, to determine the L1-SINR of the current beam and the L1-SINR of the new beams. For example, one or more of the above methods can be implemented according to predefined methods in the standard or through dynamic configuration.

[0089] In another embodiment, if the resource settings corresponding to new beams and current beams are different, then both use only their respective first resource settings, i.e., CMR as the resource for L1-SINR measurement and calculation.

[0090] In addition, in this embodiment, if a valid time window is predefined or configured in the standard, and the valid time window refers to the valid time length of the L1-SINR corresponding to the current beam and / or new beams respectively, then UE2 can determine the L1-SINR under the current beam and / or new beams within at least one valid time window.

[0091] It should be noted that, in this embodiment, the method for determining L1-SINR is not specifically limited. UE2 can determine the L1-SINR of the new beams based on the RS resources corresponding to the new beams, using any existing or future signal-to-interference-plus-noise ratio (SIR) calculation method. Similarly, UE2 can determine the L1-SINR of the current beam based on the RS resources corresponding to the current beam, using any existing or future SIR calculation method.

[0092] S204: UE2 sends the L1-SINR of the first beam and / or the L1-SINR of the second beam to network device 1.

[0093] In this process, UE2 can first compare the reference signal quality of new beams and current beams, for example, compare their L1-SINR, and determine whether the conditions for event triggering, i.e. the aforementioned preset conditions, are met based on the comparison results.

[0094] Then, if the preset conditions are met, UE2 can send a request to network device 1. Specifically, this request can be used to request resources for sending beam reports, and the content of the beam report can include the L1-SINR of the new beams and / or the L1-SINR of the current beam. Thus, after UE2 obtains the resources for sending beam reports, it can send the beam report to network device 1. Alternatively, if the preset conditions are met, UE2 can send a notification to network device 1 to send a beam report on pre-configured resources, thereby sending the beam report on the pre-configured resources. The content of the beam report can include the L1-SINR of the new beams and / or the L1-SINR of the current beam.

[0095] In addition, in some applications, the quality of new beams and current beams can be compared by L1-RSRP. This embodiment does not limit this, and any existing or future method of measuring, calculating and comparing the L1-SINR of the two beams can be used.

[0096] Furthermore, for cases where both L1-RSRP and L1-SINR metrics are supported for measurement, network device 1 can be configured to use either of these metrics for measurement via Radio Resource Control (RRC) signaling.

[0097] Alternatively, network device 1 can use downlink control signaling to instruct the use of any of these metrics for measurement, such as Medium Access Control Element (MAC CE) signaling or Downlink Control Information (DCI) signaling.

[0098] Alternatively, UE2 can choose to report the result of either L1-RSRP or L1-SINR based on the difference between the results of these two metrics, or UE2 can directly report the results of both metrics. Then, UE2 can further report the adopted metrics to network device 1 through an indication message or the aforementioned beam report. Specifically, in the case where UE2 reports to network device 1 through a beam report, the beam report can include an indicator, such as a 1-bit indicator bit, to indicate the adopted metrics. Alternatively, the beam report can use a predefined format to indicate the adopted metrics, such as predefining the bit length of the content reported in the beam report, with different bit lengths corresponding to different metrics; or predefining the bit length of L1-RSRP and / or L1-SINR corresponding to the RS resources in the beam report, with different bit lengths of L1-RSRP and / or L1-SINR corresponding to different metrics.

[0099] As mentioned in the embodiment shown in Figure 2 above, network device 1 can send configuration information to UE2, which is used to configure the RS resource set. Accordingly, in practical applications, the RS resources in the RS resource set can be updated via signaling. Based on this, for ease of understanding, the update process of the RS resources in the RS resource set will be explained in detail below with reference to Figure 3. Here, for ease of understanding and explanation, the example applied to the communication system shown in Figure 1 will still be used for illustration.

[0100] Referring to Figure 3, a flowchart of another communication method is shown. As shown in Figure 3, the flow of this communication method includes the following steps.

[0101] S301: Network device 1 sends a signaling message to UE2, which is used to indicate the update of the RS resource corresponding to the first beam or the RS resource corresponding to the second beam.

[0102] The aforementioned signaling can be at least one of MAC CE signaling, RRC signaling, and Radio Link Control (RLC) signaling.

[0103] In practical applications, the first beam mentioned in this embodiment can be referred to as the new beams, and the second beam can be referred to as the current beam. The RS resources corresponding to both the current beam and the new beams can be updated via the aforementioned signaling. For ease of understanding, the following detailed explanation will focus on updating the RS resources corresponding to the new beams.

[0104] As mentioned earlier, network device 1 can pre-configure the RS resource set in a CSI-ReportConfiguration corresponding to the new beams, and explicitly configure the RS resources corresponding to the new beams within it. Based on this, network device 1 can update the mapping relationship between CMR, IMR, or CMR and IMR through the aforementioned signaling.

[0105] Regarding the mapping relationship described above, in the current standard, if network device 1 is configured with CMR and IMR to determine L1-SINR, then there needs to be a one-to-one correspondence between CMR and IMR, meaning the number of CMRs and IMRs must be equal. It is evident that this one-to-one mapping relationship between CMR and IMR is a relatively strict constraint. However, in practical applications, this one-to-one mapping relationship is not flexible enough, failing to prevent a single CMR from corresponding to multiple IMRs, which can easily affect the accuracy of the actually determined L1-SINR.

[0106] Based on this, in this embodiment, taking the RS resources corresponding to the new beams as including CMR and IMR as an example, the number of CMR and IMR may not be equal. Furthermore, network device 1 can pre-configure the mapping relationship between CMR and IMR, including at least one of the following: one CMR corresponds to multiple IMRs, multiple CMRs correspond to one IMR, and multiple CMRs correspond to multiple IMRs. In practical applications, network device 1 can configure the number of IMRs to be greater than or equal to 64.

[0107] For example, each RS resource can carry its own corresponding identifier. Based on this, for the case where one CMR corresponds to multiple IMRs, the CSI-ReportConfig for new beams can support multiple identifier configurations in csi-IM-ResourcesForInterference or nzp-CSI-RS-ResourcesForInterference. In this way, the identifiers corresponding to multiple IMRs can be associated with one CMR.

[0108] For cases where multiple CMRs correspond to one IMR, the `resourcesForChannelMeasurement` setting in the `CSI-ReportConfig` for new beams can also support multiple identifier configurations. In this way, the identifiers corresponding to each of the multiple CMRs can be associated with one IMR.

[0109] When multiple CMRs correspond to multiple IMRs, network device 1 can predefine the mapping relationship between multiple CMRs and multiple IMRs in the standard. Specifically, the predefinition of the mapping relationship between multiple CMRs and multiple IMRs in the standard can be implemented through multiplexing. For example, CMRId1 (CMR identified as 1) can correspond to IMRId1 (IMR identified as 1) and IMRId2 (IMR identified as 2), and CMRId2 (CMR identified as 2) can correspond to IMRId2 (IMR identified as 2) and IMRId3 (IMR identified as 3). Alternatively, network device 1 can also dynamically configure the mapping relationship between multiple CMRs and multiple IMRs through RRC signaling or other downlink signaling, which is not limited here.

[0110] As one possible implementation, based on the above-mentioned mapping relationship configured in network device 1, taking the RS resources corresponding to the new beams, which include CMR and IMR, as an example, when network device 1 updates the CMR in the RS resources corresponding to the new beams through signaling, it can also update the IMR and / or the mapping relationship between CMR and IMR.

[0111] As an example, regarding the process of sending signaling in step S301 above, in this embodiment, network device 1 may specifically send a first signaling to UE2. The first signaling is used to indicate updating the CMR and IMR in the RS resources corresponding to the new beams, or the first signaling is used to indicate updating the mapping relationship and the CMR in the RS resources corresponding to the new beams, or the first signaling is used to indicate updating the mapping relationship and the CMR and IMR in the RS resources corresponding to the new beams.

[0112] Specifically, regarding the process of updating the CMR and IMR as indicated by the first signaling, UE2 can subsequently determine the IMR corresponding to the updated CMR based on the mapping relationship, and then update the corresponding IMR. Similarly, regarding the process of updating the CMR and mapping relationship as indicated by the first signaling, UE2 can subsequently update the mapping relationship based on the updated CMR. Again, regarding the process of updating the CMR, IMR, and mapping relationship as indicated by the first signaling, UE2 can subsequently determine the IMR corresponding to the updated CMR based on the mapping relationship, update the corresponding IMR, and then update the mapping relationship based on the updated IMR and the updated CMR.

[0113] Additionally, it should be noted that if the IMR is not indicated in the first signaling, then in the mapping relationship, the updated CMR can be matched with the original, unupdated IMR that corresponds to that CMR.

[0114] In this embodiment, for ease of understanding, the meaning of the first signaling will be explained in detail below with reference to Figure 4. Figure 4 illustrates the updating of one CMR as an example, but in actual applications, the first signaling can instruct the updating of multiple CMRs respectively.

[0115] As shown in Figure 4, the first signaling may specifically include the first field IM1, the second field IM2, the third field M, and the fourth field csi-IM-ResourceId.

[0116] The IM1 field indicates whether the first signaling supports updating the IMR.

[0117] Specifically, if the value of field IM1 is the first value, such as IM1 being 0, then the first signaling can specifically indicate that only CMR updates are supported; if the value of field IM1 is the second value, such as IM1 being 1, then the first signaling can specifically indicate that both CMR and IMR updates are supported.

[0118] It should be noted that this embodiment does not specifically limit the values ​​of the first and second values; the 0 or 1 here is merely an illustrative example.

[0119] As mentioned earlier, Figure 4 uses updating one CMR as an example. Accordingly, the IM2 field can indicate whether the first signaling updates the IMR corresponding to the shown CMR.

[0120] Specifically, if the value of field IM1 is the second value and the value of field IM2 is the third value, for example, if field IM1 is 1 and field IM2 is 0, then the first signaling can specifically instruct the CMR shown in Figure 4 to be updated, but not the IMR corresponding to the CMR; if the value of field IM1 is the second value and the value of field IM2 is the fourth value, for example, if field IM1 is 1 and field IM2 is 1, then the first signaling can specifically instruct the CMR shown in Figure 4 to be updated, and the IMR corresponding to the CMR to be updated.

[0121] It should be noted that this embodiment does not specifically limit the values ​​of the third and fourth values; the 0 or 1 here is merely an illustrative example.

[0122] Furthermore, as mentioned earlier, the mapping relationship between CMR and IMR supports the case where one CMR corresponds to multiple IMRs. Based on this, when one CMR corresponds to multiple IMRs, field M can indicate whether the IMR indicated by field csi-IM-ResourceId, which is located on the same line as field M in the first signaling, is the IMR corresponding to the CMR shown in Figure 4.

[0123] Specifically, if field IM1 is the second value, field IM2 is the fourth value, and field M is the fifth value (e.g., field IM1 is 1, field IM2 is 0, and field M is 0), then the first signaling can specifically indicate that the IMR indicated by field csi-IM-ResourceId, which is in the same row as field M, is the last IMR corresponding to the CMR shown in Figure 4. In other words, if the first signaling shown in Figure 4 can indicate updating other CMRs, then the next row of fields after field M represents the information of those other CMRs. If field IM1 is the second value, field IM2 is the fourth value, and field M is the sixth value (e.g., field IM1 is 1, field IM2 is 0, and field M is 1), then the first signaling can specifically indicate that the IMR indicated by field csi-IM-ResourceId, which is in the same row as field M, is not the last IMR corresponding to the CMR shown in Figure 4. In other words, the next row of fields after field M still represents the information of the IMR corresponding to that CMR.

[0124] It should be noted that this embodiment does not specifically limit the values ​​of the fifth and sixth values; the 0 or 1 here are merely illustrative examples.

[0125] In addition, as shown in Figure 4, the first signaling also includes the field R, the field Serving Cell ID, the field DL BWP ID, the field nzp-CSI-RS-ResourceSetId / csi-SSB-ResourceSetId, the field nzp-CSI-RS-ResourceId 0 / ssb 0, and the field nzp-CSI-RS-ResourceId n0 / ssb n0.

[0126] In this context, field R is a reserved bit and does not indicate any specific information; field Serving Cell ID indicates the identifier of the serving cell corresponding to UE2; field DL BWP ID indicates the identifier of the Downlink Bandwidth Part (DBP); and fields nzp-CSI-RS-ResourceSetId / csi-SSB-ResourceSetId indicate the identifier of the CMR (including NZP CSI-RS or SSB), i.e., the CMR shown in Figure 4. Further, in the first signaling shown in Figure 4, field nzp-CSI-RS-ResourceId 0 / ssb 0 indicates the identifier of the CMR before the update; and field nzp-CSI-RS-ResourceId n0 / ssb n0 indicates the identifier of the updated CMR.

[0127] As another possible implementation, based on the above-mentioned mapping relationship configured in network device 1, taking the RS resources corresponding to the new beams, which include CMR and IMR, as an example, network device 1 can update the mapping relationship between IMR and / or CMR and IMR in the RS resources corresponding to the new beams through signaling, without updating the CMR.

[0128] As an example, regarding the signaling process in step S301 above, in this embodiment, network device 1 can specifically send a second signaling to UE2. This second signaling is used to instruct the updating of the IMR in the RS resource corresponding to the new beams, or it is used to instruct the updating of the mapping relationship and the IMR in the RS resource corresponding to the new beams. Specifically, regarding the process of updating the IMR and mapping relationship indicated by the first signaling, UE2 can subsequently update the mapping relationship based on the updated IMR.

[0129] Additionally, it should be noted that since the second signaling does not indicate an update to the CMR, in the mapping relationship, the updated IMR simply corresponds to the original, unupdated CMR that the IMR originally belonged to.

[0130] In this embodiment, for ease of understanding, the meaning of the second signaling will be specifically described below with reference to Figure 5. As shown in Figure 5, the second signaling may specifically include a fifth field, csi-IM-ResourceId. The csi-IM-ResourceId field may carry an identifier of the IMR to indicate whether the second signaling updates the IMR corresponding to that identifier.

[0131] Specifically, if the identifier of the IMR carried by the csi-IM-ResourceId field indicates that the IMR does not belong to the RS resource currently corresponding to the new beams, then the second signaling can specifically instruct the IMR indicated by the csi-IM-ResourceId field to be updated to the RS resource corresponding to the new beams.

[0132] Furthermore, if the csi-IM-ResourceId field includes multiple fields, and each field can indicate the identifier of an IMR, meaning the csi-IM-ResourceId field carries the identifiers of multiple IMRs, then the second signaling can specifically instruct the mapping relationship to be updated based on the order in which the identifiers of the multiple IMRs are arranged in the csi-IM-ResourceId field. For example, if in the mapping relationship, the identifiers of the multiple IMRs corresponding to one CMR are 1, 2, and 3, and in the aforementioned second signaling, the order in which the identifiers of the multiple IMRs are arranged in the csi-IM-ResourceId field is CMR with identifier 1, CMR with identifier 3, and CMR with identifier 4, then the aforementioned mapping relationship can be updated based on the IMRs with identifiers 1, 3, and 4.

[0133] In addition, as shown in Figure 5, the second signaling also includes the field R, the field Serving Cell ID, the field DL BWP ID, and the fields CSI-ReportConfigId / CSI-ResourceConfigId.

[0134] Among them, field R is a reserved bit and does not indicate any specific information for the time being; field Serving Cell ID is used to indicate the identifier of the serving cell corresponding to UE2; field DL BWP ID is used to indicate the identifier of the downlink bandwidth part (DBP); field CSI-ReportConfigId / CSI-ResourceConfigId is used to indicate the identifier of a CSI-ReportConfiguration corresponding to new beams or the identifier of CSI resource settings CSI-ResourceConfig corresponding to new beams.

[0135] Furthermore, as mentioned earlier, the RS resources corresponding to both the current beam and new beams can be updated using the aforementioned signaling. Therefore, for ease of understanding, the following explanation will use updating the RS resources corresponding to the current beam as an example.

[0136] As one possible implementation, based on the above-mentioned mapping relationship configured in network device 1, taking the RS resources corresponding to the current beam, which include CMR and IMR, as an example, network device 1 can update the mapping relationship between IMR and / or CMR and IMR in the RS resources corresponding to the current beam through signaling, without updating CMR.

[0137] As an example, regarding the signaling process in step S301 above, in this embodiment, network device 1 can specifically send a third signaling message to UE2. This third signaling message is used to instruct the updating of the IMR in the RS resource corresponding to the current beam, or the third signaling message is used to instruct the updating of the mapping relationship and the IMR in the RS resource corresponding to the current beam. Specifically, regarding the process of updating the IMR and mapping relationship indicated by the third signaling message, UE2 can subsequently update the mapping relationship based on the updated IMR.

[0138] Additionally, it should be noted that since the third signaling does not indicate the CMR update, in the mapping relationship, the updated IMR simply corresponds to the original, unupdated CMR that the IMR originally corresponded to.

[0139] In this embodiment, for ease of understanding, the meaning of the third signaling will be specifically described below with reference to Figure 6. As shown in Figure 6, the third signaling may specifically include a sixth field, csi-IM-ResourceId. The csi-IM-ResourceId field may carry an identifier of the IMR to indicate whether the third signaling updates the IMR corresponding to that identifier.

[0140] Specifically, if the identifier of the IMR carried by the csi-IM-ResourceId field indicates that the IMR does not belong to the RS resource currently corresponding to the current beam, then the third signaling can specifically instruct the IMR indicated by the csi-IM-ResourceId field to be updated to the RS resource corresponding to the current beam.

[0141] Furthermore, if the csi-IM-ResourceId field includes multiple fields, and each field can indicate the identifier of an IMR, that is, the csi-IM-ResourceId field carries the identifiers of multiple IMRs, then the third signaling can specifically instruct the mapping relationship to be updated based on the order of the identifiers of multiple IMRs in the csi-IM-ResourceId field.

[0142] In addition, as shown in Figure 6, the third signaling also includes the field R, the field Serving Cell ID, the field DL BWP ID, and the field TCI state ID.

[0143] Among them, field R is a reserved bit and does not indicate any specific information for the time being; field Serving Cell ID is used to indicate the identifier of the serving cell corresponding to UE2; field DL BWP ID is used to indicate the identifier of the downlink bandwidth part (DBP); field TCI state ID is used to indicate the identifier of the indicated TCI state, that is, the identifier of the RS resource corresponding to the current beam.

[0144] Furthermore, it should be noted that when network device 1 updates the CMR in the RS resource corresponding to the current beam via signaling, it can also simultaneously update the IMR in the RS resource corresponding to the current beam and / or the mapping relationship between the CMR and IMR. For this implementation process, please refer to the implementation process and corresponding figures for updating the CMR in the RS resource corresponding to new beams in the above embodiments, which will not be repeated here.

[0145] S302: UE2 updates the RS resources corresponding to the first beam or the RS resources corresponding to the second beam according to the signaling.

[0146] In this process, UE2 can update the RS resources corresponding to the new beams or the current beam according to the signaling mentioned above. For example, UE2 can update the RS resources in the RS resource set by adding or modifying RS resources according to the signaling.

[0147] Therefore, based on the relevant content of steps S301-S302 above, it can be seen that in this embodiment, network device 1 can update the mapping relationship between CMR, IMR or CMR and IMR in the above RS resource set through signaling.

[0148] The hardware implementation of network devices and UEs will be further described below with reference to Figures 7 and 8.
