Description

Beam measurement method and related device

[0001] The present application claims priority to the Chinese patent application No. 202410499274.3, filed on April 20, 2024, and entitled "Beam measurement method and related device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, in particular to a beam measurement method and related device. BACKGROUND

[0003] The existing measurement of Layer 1 (L1) is to measure the signal quality under the centralized unit (CU) of the same set, specifically: the terminal device UE measures according to the reference signal (RS) pre-configured by the network device, and the UE reports the measurement result based on the reporting configuration after the measurement is completed. The RS for the existing L1 measurement of the neighboring area is the synchronization signal block (SSB), and this L1 measurement of the neighboring area based only on the SSB cannot provide detailed information of the downlink channel. In addition to the serving cell, the UE needs to frequently measure and subsequently frequently report the measurement of the pre-configured beams of the neighboring cell based on different types of reference signals. SUMMARY

[0004] The present application provides a beam measurement method and related device, which reduces the number of measurements and reports of the neighboring cell, thereby saving signaling and reducing energy consumption.

[0006] In the above manner, in the configuration stage, the beams of the neighboring area are pre-configured; in the L1 measurement, the measurement of the beams of the neighboring area is activated by the measurement activation information, and since the first L1 measurement only includes part of the L1 measurement, the number of measurements and reports of the neighboring cell can be reduced, thereby saving signaling and reducing energy consumption.

[0007] In a possible implementation, the beam measurement related information includes L3 measurement configuration information, and the L3 measurement configuration information includes one or more of the following information: associated L1 measurement, measurement object index MO ID, and measurement index MeasID.

[0008] In the above manner, since the L3 layer further processes and filters the raw data provided by the L1 layer, and the L3 layer can manage the radio resource control, the L3 measurement configuration information is preconfigured, and subsequent measurement can be performed only on part of the beams related to the L3 measurement, thereby saving the number of measurements of the terminal device and reducing the energy consumption of the terminal device.

[0009] In a possible implementation, the beam measurement related information includes one or more of the following: beam related index, channel state information (CSI) resource related information, grouping related information, first preset beam, and related information of the first preset beam, the CSI resource related information includes a CSI resource set and a CSI resource set index, or a CSI resource and a CSI resource index, the grouping related information is used to indicate one or more of the following groupings: candidate resource grouping, centralized unit (CU) grouping, distributed unit (DU) grouping, cell grouping, or newly defined grouping, the candidate resource grouping includes at least one CSI resource set or at least one CSI resource, and the related information of the first preset beam includes an association relationship between the first preset beam and the grouping related information.

[0021] In a possible implementation, if the first measurement result satisfies the measurement activation condition, the first L1 measurement is performed based on the beam measurement related information.

[0022] In this way, the network device sends the measurement activation condition of the second measurement to the terminal device, and the terminal device determines whether to activate the second measurement.

[0057] Reference to "an embodiment" or "the embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily referring to a common or identical embodiment. It is appreciated that the embodiments described herein can be combined with other embodiments.

[0058] In order to facilitate the understanding of the scheme provided by the embodiments of the present application, the related concepts involved in the embodiments of the present application are introduced as follows:

[0059] CSI framework: In NR, the configuration of CSI is divided into two parts: CSI resource configuration and reporting configuration. The CSI resource configuration is used to configure the reference information for calculating the CSI, and the reporting configuration is used to configure the behavior of reporting the CSI. Since the present scheme mainly relates to the CSI resource configuration, the CSI resource configuration is further introduced as follows:

[0060] CSI resource configuration: The resource of CSI is configured according to the resource set. Each UE can be configured with multiple resource set lists through resource configuration signaling, and each resource set list includes multiple resource sets. Each resource set is composed of resources for channel measurement and resources for interference measurement. The CSI resource set can be a NZP CSI-RS resource set (each NZP CSI-RS resource set is configured by NZP-CSI-RS-ResourceSet IE) and / or a SSB (resource) set (each SSB resource set is configured by CSI-SSB-ResourceSet IE); or a CSI-IM resource set (each CSI-IM resource set is configured by CSI-IM-ResourceSet IE). The time domain behavior of the CSI-RS resource can be configured by the high layer parameter resourceType to the following three types: periodic, semi-persistent and aperiodic. resourceType does not apply to the SSB resource set referenced in csi-SSB-ResourceSetList. The following will be further introduced for the above three types respectively:

[0061] Periodic CSI-RS resource: The approximate signaling of the periodic CSI resource configuration is shown in FIG. 1A. The network device configures and reports the CSI-RS resource to the terminal device, which can be carried in the RRC signaling. After the CSI-RS resource and reporting configuration is completed, the network device continuously sends the CSI-RS to the terminal device according to the period.

[0062] Semi-persistent CSI-RS resource: The approximate signaling of the periodic CSI-RS resource configuration is shown in FIG. 1B. The difference between the semi-persistent CSI-RS and the periodic CSI-RS is that the actual sending of the semi-persistent CSI-RS is activated by the MAC control unit (MAC Control Element, MAC CE). Once the semi-persistent CSI-RS resource is activated, the network device will send according to the configured sending period, that is, in FIG. 1B, after the MAC CE takes effect, the behavior of the semi-persistent CSI-RS resource is the same as that of the periodic CSI-RS resource.

[0063] As shown in FIG. 1C, FIG. 1C is a semi-persistent CSI-RS resource activation MAC CE, and the meanings of the fields in the semi-persistent CSI resource activation MAC CE are as follows:

[0064] A / D: This field is used to indicate whether to activate / deactivate the specified semi-persistent CSI-RS resource set. If the field is 1, it means to activate the specified semi-persistent CSI-RS resource set; if the field is 0, it means to deactivate the specified semi-persistent CSI-RS resource set.

[0065] Serving Cell ID: This field is used to indicate the serving cell ID to which the MAC CE applies, i.e., the physical cell identity of the serving cell.

[0066] BWP ID: This field is used to indicate the DL BWP to which the MAC CE applies.

[0067] SP CSI-RS resource set ID: This field is the index of the CSI-RS resource set, indicating the semi-persistent CSI-RS resource set that should be activated / deactivated. The length of this field is 6 bits, so it can indicate 64 CSI-RS resource sets (as mentioned above, the UE can also be configured with a maximum of 64 CSI-RS resource sets).

[0068] IM: This field is used to indicate whether the SP CSI-IM resource set ID field exists. If the field is 1, it means that the SP CSI-IM resource set ID field exists; if the field is 0, it means that it does not exist.

[0069] SP CSI-IM resource set ID: This field is the index of the CSI-IM-ResourceSet, indicating the semi-persistent CSI-IM resource set that should be activated / deactivated. The length of this field is 6 bits, so it can indicate 64 CSI-IM resource sets (as mentioned above, the UE can also be configured with a maximum of 64 CSI-IM resource sets).

[0070] TCI State ID: This field contains the TCI-StateId of a TCI state, used to indicate the QCL resource of the NZP CSI-RS resource in the semi-persistent NZP CSI-RS resource set corresponding to the SP CSI-RS resource set ID field. TCI state ID 0 represents the TCI state of the first NZP CSI-RS resource in the semi-persistent NZP CSI-RS resource set, and so on. The length of this field is 7 bits. If the A / D field is set to 0, the TCI State ID will not appear.

[0071] R: Reserved bit, set to 0.

[0072] Aperiodic CSI-RS resource: for the aperiodic CSI-RS resource, it is triggered by DCI Format 0_1 or DCI Format 0_2 in the downlink control information (DCI).

[0073] The above three types of CSI-RS resources all cause large energy consumption and signaling overhead, specifically:

[0074] For the periodic CSI-RS resource, the measurement of the periodic CSI-RS resource does not need to be activated / triggered, so after the configuration, all the pre-configured beams will be measured and subsequently reported. This way causes large energy consumption and signaling overhead. For example, 10 CSI-RSs are configured, of which only 3 CSI-RSs are needed in the current scenario. But after the configuration is completed, the terminal device will still periodically send the 10 CSI-RSs. The network device sending CSI-RS to the terminal device will cause signaling waste, and the terminal device measuring the 10 CSI-RSs will cause energy waste of the terminal device. The terminal device subsequently reporting the measurement results of the 10 CSI-RSs to the network device will also cause signaling waste.

[0075] For the non-persistent CSI-RS resource, although the measurement of the non-persistent CSI-RS resource needs to be activated / triggered, the semi-persistent CSI-RS resource activation MAC CE contains an index for indicating the CSI-RS Resource Set, but in the inter CU scenario (the scenario of CU interaction), if the network device configures all the beams under multiple CUs, the index of the CSI-RS Resource Set will indicate all the pre-configured beams, as with the above periodic CSI-RS, it causes large energy consumption and signaling overhead.

[0076] For the aperiodic CSI-RS resource, it will also cause large energy consumption and signaling overhead as with the above non-persistent CSI-RS resource, which will not be repeated here.

[0077] To solve the above problems of large energy consumption and signaling overhead, the embodiment of the present application provides a beam measurement method. When measuring the beams of the adjacent area, the beam measurement method also introduces an activation process for the periodic CSI-RS resource, and groups the CSI-RS sets in the CSI-RS resource set list of the periodic CSI-RS resource, the non-persistent CSI-RS resource and the aperiodic CSI-RS resource. Thus, when measuring, the measurement can be based on grouping to avoid measuring unnecessary CSI-RS resources. Therefore, the energy consumption and signaling overhead are reduced.

[0078] As shown in FIG. 2, FIG. 2 shows a possible and non-limiting communication system schematic diagram. As shown in FIG. 2, the communication system includes a terminal device 201 and a network device 202. FIG. 2 takes one terminal device 201 and one network device 202 as an example. There can be more terminal devices 201 and network devices 202 in the communication system, and the embodiment of the present application does not make any limitation.

[0079] I. Terminal device 201

[0080] The terminal device 201 can also be referred to as a terminal, a user equipment (UE), a mobile station, a mobile terminal, an electronic device, etc. The terminal device 201 can be widely applied to various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal device 201 can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc.

[0081] II. Network device 202

[0082] The network device 202 can also be referred to as an access network device, and sometimes can also be referred to as a radio access network (RAN) node, a RAN entity or an access node, etc., which constitutes a part of a communication system and helps the terminal device 102 to implement wireless access. In a possible scenario, the network device 202 can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The network device 202 can be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or a wireless controller in a CRAN scenario. In a possible embodiment, the network device 202 can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU).

[0083] If the network device 202 is a gNB, the network device 202 can include two physical entities, namely a centralized unit (CU) and a distributed unit (DU). Each gNB has one CU, and the CU controls multiple DUs, for example, one CU can be connected to more than 100 DUs. Each DU can support one or more cells, so one gNB can control hundreds of cells.

[0084] Based on the above description, a beam measurement method provided by the embodiment of the present application is further described in detail below. As shown in FIG. 3, the beam measurement method includes the following steps: step 301 and step 302.

[0085] 301. The network device sends first configuration information and measurement activation information to the terminal device, the first configuration information including beam measurement related information, and the beam measurement related information including beam information of a neighboring area. Correspondingly, the terminal device receives the first configuration information and the measurement activation information sent by the network device.

[0086] The first configuration information includes beam measurement related information and / or measurement activation configuration. The beam measurement related information includes, but is not limited to, beam information of a neighboring cell. The beam measurement related information can also include other beam information, such as beam information of a serving cell, and the like. In the case that the terminal device performs first L1 measurement, the first configuration information includes measurement activation configuration in addition to the beam measurement related information. The measurement activation information includes measurement activation indication and / or measurement activation condition.

[0087] The measurement activation configuration is a configuration sent by the network device to the terminal device. When the terminal device receives the first configuration information including the measurement activation configuration, the terminal device does not perform measurement on the related beams except the measurement activation configuration in the first configuration information, or performs measurement related to the measurement activation configuration in the first configuration information for the first time. In the case that the terminal device activates the first L1 measurement, the measurement activation information includes measurement activation condition. The measurement activation condition is a condition sent by the network device to the terminal device. The measurement activation condition is used to enable the terminal device to determine whether to perform the first L1 measurement.

[0088] In a possible embodiment, the beam measurement related information includes L3 measurement configuration information, and the L3 measurement configuration information includes one or more of the following information: associated L1 measurement, measurement object index MO ID, and measurement index MeasID.

[0089] The associated L1 measurement is part of the L1 measurement related to the L3 measurement configuration information. For example, the L1 measurement measures beams 1, 2, 3, 4, and 5. The associated L1 measurement of L3 measurement A is beams 1, 2, and 3. The associated L1 measurement of L3 measurement B is beams 4 and 5. The different L3 measurements can be indicated by the measurement object index MO ID and / or the measurement index MeasID. That is, the L3 measurement is indicated as L3 measurement A or L3 measurement B by the measurement object index MO ID and / or the measurement index MeasID.

[0090] In a possible embodiment, the beam measurement related information includes one or more of the following: beam related index, channel state information (CSI) resource set related information, grouping related information, first preset beam, and related information of the first preset beam. The CSI resource set related information includes a CSI resource set and a CSI resource set index, or a CSI resource and a CSI resource index. The grouping related information is used to indicate one or more of the following groupings: candidate resource set grouping, centralized unit (CU) grouping, distributed unit (DU) grouping, cell grouping, or newly defined grouping. The candidate resource set grouping includes at least one CSI-RS resource set. The related information of the first preset beam includes an association relationship between the first preset beam and the grouping related information.

[0091] Wherein, the beam related index is used to indicate the beam of the neighbor cell, for example, 1-beam 1, 1 is the related index of beam 1, and beam 1 is the beam of the neighbor cell. The CSI resource set related information can be the following two kinds of information: CSI resource set and CSI resource set index, or CSI resource and CSI resource index. The CSI resource set and CSI resource can refer to the introduction in the above related concept, and the present application does not make redundant description here. The grouping related information includes grouping and the beam in the grouping, for example: grouping 1 (beam 1, beam 2 and beam 3). The first preset beam is a preset beam, and the related information of the first preset beam includes the grouping related information corresponding to the first preset beam, which can also be understood as the grouping corresponding to the first preset beam, for example: beam 4-grouping 1 (beam 1, beam 2 and beam 3), beam 4 is the first preset beam, grouping 1 is the grouping corresponding to beam 4, and beam 1, beam 2 and beam 3 are the beams in grouping 1. The related information of the first preset beam is the mapping relationship between the beam and the grouping, such as the corresponding relationship between beam 4 and grouping 1.

[0092] Wherein, the grouping related information can include the index of the candidate resource grouping, the index of the CU grouping, the index of the DU grouping, the index of the cell grouping, or the index of the newly defined grouping. The above multiple indexes are used to indicate the association relationship between the beams. The grouping can be based on the candidate resource set grouping, the CU grouping, the DU grouping, the cell grouping or the newly defined grouping. The candidate resource set grouping includes at least one CSI-RS resource set. The candidate resource set grouping includes all candidate beam groupings, the CU grouping includes the beams under the same CU, the DU grouping includes the beams under the same DU, the cell grouping includes the groupings under the same cell, and the newly defined grouping includes part of the beams of the neighbor cell.

[0093] For example, the beams of the neighbor cell A are beam 1, beam 2 and beam 3, and the beams of the neighbor cell B are beam 4 and beam 5. The cell grouping divides beam 1, beam 2 and beam 3 into a group, and divides beam 4 and beam 5 into another group. The newly defined grouping divides beam 1 and beam 3 into a group.

[0094] For example, the grouping related information indicating the form of the grouping can be the following two kinds: one is grouping A (beam 1, beam 2, beam 3); grouping B (beam 4, beam 5). The other is beam 1-grouping A, beam 2-grouping A, beam 3-grouping A, beam 4-grouping B, and beam 5-grouping B. No matter which form is used, the grouping related information can indicate the relationship between the grouping and the beam.

[0095] Optionally, the first configuration information can further include L3 measurement configuration information related to L1 measurement, etc. The first configuration information can further include more information, which is not limited in the present application.

[0096] In a possible embodiment, the beam information of the serving cell and the beam information of the neighbor cell are CSI-RS resources of the serving cell and CSI-RS resources of the neighbor cell.

[0097] In a possible embodiment, the beam measurement related information further includes a resource type (e.g. periodic, semi-persistent or aperiodic). If the first configuration information includes a measurement activation condition, that is, the network device configures an activation condition for the terminal device, and the terminal device receives a beam with a resource type of semi-persistent or aperiodic in the beam measurement related information, the measurement and subsequent reporting are triggered.

[0098] In a possible embodiment, for the downlink of NR, the index of the transmitted RS is used as the reference of the best beam. When the beam is indicated, the indication can be based on the TCI state, and the communication is based on the reference signal corresponding to the TCI state.

[0099] In a possible embodiment, the measurement activation indication includes an index of an L3 event, or a measurement object index MO ID, or a measurement index MeasID.

[0100] In a possible embodiment, the measurement activation indication includes one or more of the following: a beam related index, CSI resource set related information, grouping related information, a first indication, and the first indication is used to indicate all beams in the first configuration information.

[0101] For example, the CSI resource set related information is shown in FIG. 4A, the grouping related information is shown in FIG. 4B, the first indication is shown in FIG. 4C, and the beam related index is shown in FIG. 4D, which includes at least one CSI-RS index. Optionally, the first indication can be a code (e.g. CIR_0, CIR_1, CIR_2, etc.).

[0102] For example, if the measurement activation indication is a beam related index, the beam related index indicates beams 1, 2 and 3, and after the terminal device receives the measurement activation indication, the terminal device performs measurement on beams 1, 2 and 3, that is, the first L1 measurement is measurement on beams 1, 2 and 3.

[0103] For example, if the measurement activation indication is CSI resource set related information, the CSI resource set related information indicates that the CSI resource set is CSI resource set A, and the CSI resource set A includes beams 1 and 3, the terminal device receives the measurement activation indication and performs measurement on beams 1 and 3, that is, the first L1 measurement is measurement on beams 1 and 3.

[0104] Similarly, if the measurement activation indication is group related information and the first indication, the first L1 measurement is measurement on the beams indicated by the measurement activation indication. Details are not described herein.

[0105] In a possible embodiment, the network device can simultaneously send the first configuration information and the measurement activation information; or the network device can first send the first configuration information, and then send the measurement activation information after receiving the feedback of the terminal device; or the network device can first send the measurement activation information, and then send the first configuration information after the terminal device stores the measurement activation information.

[0106] For example, as shown in FIG. 4A, the CSI resource set related information (SP CSI-RS resource set ID in FIG. 4A).

[0107] In a possible embodiment, the neighbor cell CSI-RS resource in the first configuration information is a periodic CSI-RS resource.

[0108] 302. The terminal device performs the first L1 measurement based on the first configuration information and the measurement activation information, and the first L1 measurement includes measurement on at least one beam of a neighbor cell, the at least one beam of the neighbor cell being a beam configured in the beam measurement related information.

[0109] The neighbor cell can be one or more candidate cells adjacent to the serving cell. The serving cell and the candidate cell can be cells located in the same CU, or can be cells located in different CUs. If the serving cell and the candidate cell are located in the same CU, the serving cell and the candidate cell can be located in the same DU, or the serving cell and the candidate cell can be located in different DUs. Details are not limited herein.

[0110] In a possible embodiment, the terminal device performs the L1 measurement based on the first configuration information and the measurement activation information includes: the terminal device performs first measurement based on the first configuration information to obtain a second measurement result, the second measurement result being used to determine whether to activate related L1 measurement; and the terminal device performs second measurement based on the second measurement result, the first configuration information and the measurement activation information, the second measurement being the first L1 measurement.

[0111] It can be understood that the measurement procedure includes two measurement procedures: the first measurement to determine whether the second measurement is performed; if it is determined that the second measurement is needed based on the measurement result of the first measurement, the second measurement is performed.

[0112] The behavior of determining whether the second measurement is needed can be performed by the network device or by the terminal device. That is, the network device can activate the L1 measurement, specifically, the network device can send a measurement activation indication to activate the terminal device to perform the L1 measurement; or the terminal device can activate the L1 measurement, specifically, the terminal device can determine whether to activate the L1 measurement based on the measurement activation condition pre-configured by the network device.

[0113] The above two ways of activating the L1 measurement are introduced as follows:

[0114] The first way is that the network device activates the L1 measurement.

[0115] In a possible embodiment, the measurement activation information is a measurement activation indication, and the measurement activation indication is used to instruct the terminal device to perform the first L1 measurement, and the first L1 measurement is the L1 measurement related to the measurement activation indication.

[0116] The measurement activation indication can be carried in a Medium Access Control Control Element (MAC CE) or the measurement activation indication can be carried on a Downlink Control Information (DCI). Specifically, if the activated L1 measurement is a periodic beam resource, the network device can carry the measurement activation indication in the MAC CE or the measurement activation indication can be carried on the DCI; if the activated L1 measurement is a semi-persistent beam resource, the network device can carry the measurement activation indication in the MAC CE; if the activated L1 measurement is an aperiodic beam resource, the network device can carry the measurement activation indication on the DCI. The MAC CE and the DCI can be referred to the description in the above, which will not be repeated here.

[0117] In a possible embodiment, after the network device sends the first configuration information to the terminal device, the network device sends the measurement activation indication to the terminal device.

[0118] In the case that the network device activates the L1 measurement, the basis for the network device to determine whether to send the measurement activation indication can be the L3 measurement result, the first preset beam measurement result, and the measurement result of the SSB when the first preset beam is the SSB. The three cases are further introduced as follows:

[0119] Case 1: the judgment basis of the network device is the L3 measurement result.

[0120] Wherein, L1 is the first layer, responsible for the measurement of the original signal strength of the physical layer, such as the reference signal receiving power (RSRP). L3 is the third layer, mainly responsible for the management of the radio resource control, including starting the measurement process, configuring the measurement parameters, and processing and reporting the measurement data from the L1 layer. The L3 layer further processes and filters the original data provided by the L1 layer.

[0121] In order to realize this case 1, it is necessary to pre-configure the L3 measurement, and to associate the L1 measurement related to the L3 measurement. As in the above step 301, the beam measurement related information includes L3 measurement configuration information, and the L3 measurement configuration information includes one or more of the following information: associated L1 measurement, measurement object index MO ID, and measurement index MeasID.

[0122] The L3 measurement configuration information also includes the corresponding relationship between the associated L1 measurement and the measurement object index, or the corresponding relationship between the associated L1 measurement and the measurement index, or the corresponding relationship between the associated L1 measurement and the L3 measurement event identifier. For example, the L1 measurement A is to measure the beams: beam 1, beam 2 and beam 3, and the L1 measurement A is associated with the measurement object index A; or the L1 measurement A is associated with the measurement index A.

[0123] Or, the corresponding relationship between the associated L1 measurement and the L3 measurement event identifier is in the form of: beam 1-measurement object index A, beam 2-measurement object index A, beam 3-measurement object index A, beam 4-measurement object index B, beam 5-measurement object index B. Wherein, beam 1, beam 2 and beam 3, the L1 measurement A is associated with the measurement object index A; beam 4 and beam 5 are associated with the measurement object index B.

[0124] Through the above configuration, when activated, the corresponding first L1 measurement pre-configured by the terminal device can be activated by indication. The indication of activation is a measurement activation indication. In one possible embodiment, the measurement activation indication includes the index of the L3 event, or the measurement object index MO ID, or the measurement index MeasID.

[0125] The measurement activation indication is used to indicate the terminal device to perform a first L1 measurement, the first L1 measurement is a beam related to an index of an L3 event in the measurement activation indication, the related beam is configured by L3 measurement configuration information in a configuration stage, or the first L1 measurement is a beam related to a measurement object index MO ID, or the first L1 measurement is a beam related to a measurement index MeasID.

[0126] For example, the beam resource set list includes five beam resources: beam resource 1, beam resource 2, beam resource 3, beam resource 4, and beam resource 5. The index of the L3 event is A1. Among them, beam resource 1, beam resource 2, and beam resource 3 are beam resources related to the A1 event. Then, when measuring, the terminal device only measures beam resource 1, beam resource 2, and beam resource 3.

[0127] The measurement activation indication includes the index of the L3 event (such as the A1 event described above).

[0128] Alternatively, the measurement activation indication includes a measurement object index. Alternatively, the L3 measurement configuration information related to the L1 measurement can also be a measurement index MeasID, where each measurement index links a measurement object to a report configuration. By configuring multiple measurement indexes, more than one measurement object can be linked to the same report configuration, and more than one report configuration can be linked to the same measurement object.

[0129] For example, the L1 measurement is a measurement on the following beams: beam 1, beam 2, beam 3, beam 4, and beam 5. The L1 measurement A is a measurement on the following beams: beam 1, beam 2, and beam 3, and the L1 measurement A is associated with a measurement object index A. If the measurement activation indication includes the measurement object index A, the terminal device performs the L1 measurement A (the first L1 measurement) based on the measurement object index A, that is, measures beam 1, beam 2, and beam 3.

[0130] Alternatively, beam 1-measurement object index A, beam 2-measurement object index A, beam 3-measurement object index A, beam 4-measurement object index B, and beam 5-measurement object index B. If the measurement activation indication includes the measurement object index A, the terminal device measures beam 1, beam 2, and beam 3 based on the measurement. Similarly, if the measurement activation indication includes the measurement object index B, the terminal device measures beam 4 and beam 5 based on the measurement.

[0131] The beam resource related to the L3 event in the pair of beam measurement related information can be a beam resource pre-grouped by the network device. The grouping manner can be to place the beam resources related to the L3 event into the same resource configuration. For example, the beam resources related to the A1 event, beam resource 1, beam resource 2, and beam resource 3 are placed into the same resource configuration. Alternatively, the beam resources related to the L3 event are indicated by the same identifier. For example, the indication of the beam resource 1 related to the A1 event is A, the indication of the beam resource 2 related to the A1 event is A, and the indication of the beam resource 3 related to the A1 event is A; the indication of the beam resource 4 related to the A2 event is B, and the indication of the beam resource 4 related to the A2 event is B.

[0132] In a possible embodiment, the terminal device receives the first configuration information and the measurement activation information sent by the network device, including: the terminal device receives the L3 measurement configuration information related to the L1 measurement sent by the network device; the terminal device performs L3 measurement based on the L3 measurement configuration information related to the L1 measurement to obtain a first measurement result; the terminal device sends the first measurement result to the network device; and the terminal device receives the measurement activation indication. Correspondingly, the network device sends the L3 measurement configuration information related to the L1 measurement to the terminal device; the network device receives the first measurement result sent by the terminal device; and the network device sends the measurement activation indication to the terminal device if the first measurement result meets the measurement activation condition.

[0133] The L3 measurement configuration information related to the L1 measurement and the measurement activation indication in the case can be referred to the above description and will not be described here.

[0134] In summary, when the network device activates the L1 measurement and the judgment basis of the network device is the L3 measurement result, the terminal device will perform two measurements, where the first measurement is the L3 measurement performed by the terminal device, and the second measurement is the first L1 measurement performed by the terminal device. In the first measurement, the terminal device does not perform L1 measurement; in the second measurement, only the beam resources related to the first L3 measurement are performed. Not only the signaling is saved, but also the energy consumption of the terminal device is reduced.

[0135] Case two, the judgment basis of the network device is the measurement result of the first preset beam.

[0136] The first preset beam is the first preset beam of the beam resource group, and one first preset beam can correspond to multiple beam resource groups, that is, different beam groups can correspond to the same first preset beam. One beam resource group can also correspond to multiple first preset beams. In a possible embodiment, the beam measurement related information includes the first preset beam, and the first preset beam is the first preset beam of the first beam resource group.

[0137] For example, the network device sends a list of beam resource sets to the terminal device, which includes five beam resources: beam resource 1, beam resource 2, beam resource 3, beam resource 4, and beam resource 5. The network device groups the five beam resources to obtain: beam resource group 1 (beam resource 1, beam resource 2, beam resource 3); and beam resource group 2 (beam resource 1, beam resource 4, beam resource 5). Among them, the beam resource 1 in the beam resource group 1 is the first preset beam, and the beam resource 4 in the beam resource group 2 is the first preset beam.

[0138] Alternatively, the beam resource 1 in the beam resource group 1 is the first preset beam, and the beam resource 1 in the beam resource group 2 is the first preset beam.

[0139] Alternatively, the beam resource 1 and the beam resource 2 in the beam resource group 1 are both first preset beams, and the beam resource 1 in the beam resource group 2 is the first preset beam.

[0140] Alternatively, the beam resource 1 and the beam resource 2 in the beam resource group 1 are both first preset beams, and the beam resource 1 in the beam resource group 2 is the first preset beam.

[0141] The above-mentioned first preset beam is the first preset beam of the grouped beam resource group. The grouping rule is further introduced as follows: in a possible embodiment, the beam measurement related information includes a first beam resource grouping. The first beam resource grouping is a first CU related beam resource configuration grouping, or the first beam resource grouping is a first DU related beam resource configuration grouping under the first CU, or the first beam resource grouping is a candidate cell related beam resource configuration grouping.

[0142] Among them, the first beam resource grouping is a first CU related beam resource configuration grouping, which means that the beam resources of the same CU are grouped. For example, the network device sends a list of beam resource sets to the terminal device, which includes five beam resources: beam resource 1, beam resource 2, beam resource 3, beam resource 4, and beam resource 5. Among them, the beam resource 1, the beam resource 2, and the beam resource 3 are beam resources of CU1. Then the network device groups the five beam resources to obtain: the beam resource 1, the beam resource 2, and the beam resource 3 are grouped.

[0143] Alternatively, the beam resources of the same DU are grouped. Alternatively, the beam resources of the same candidate cell are grouped, or the beam resources of all candidate cells are grouped.

[0144] In a possible embodiment, the first beam resource grouping is a beam resource grouping based on the locations of the serving cell and the candidate cells. For example, there are candidate cell A, candidate cell B and candidate cell C near the serving cell, and candidate cell A and candidate cell B are closer to the serving cell, and thus the beam resources of candidate cell A and candidate cell B are grouped into one group.

[0145] In a possible embodiment, the first beam resource grouping is a beam resource grouping based on the locations of part of the beams of the serving cell and the candidate cells. For example, there is candidate cell A near the serving cell, and candidate cell A includes beam resource 1, beam resource 2 and beam resource 3. The beam resource 1 and the beam resource 2 of candidate cell A are closer to the serving cell, and thus the beam resources of the beam resource 1 and the beam resource 2 are grouped into one group.

[0146] In a possible embodiment, the measurement activation indication is used to indicate the activation of the beam resources in the first beam resource grouping related to the first preset beam.

[0147] For example, the first preset beam of the first beam resource grouping is beam resource 1, the first beam resource grouping includes beam resource 2 and beam resource 3, and thus the measurement activation indication is used to indicate the activation of the beam resource 2 and the beam resource 3.

[0148] In a possible embodiment, the terminal device receives the first configuration information and the measurement activation information sent by the network device, including: the terminal device receives the beam measurement related information sent by the network device; the terminal device performs measurement on the first preset beam based on the first preset beam in the beam measurement related information, and obtains a second measurement result; the terminal device sends the second measurement result to the network device; and the terminal device receives the measurement activation indication. Correspondingly, the network device sends the beam measurement related information to the terminal device; the network device receives the second measurement result sent by the terminal device; and the network device sends the measurement activation indication to the terminal device.

[0149] That is, as shown in FIG. 5A, in this case, the terminal device first performs measurement on the RS anchor point; the network device judges whether to activate the related L1 measurement based on the first measurement result of the first preset beam; if the network device judges that the L1 measurement needs to be activated, the network device sends the measurement activation indication to the terminal device; and the terminal device performs L1 measurement based on the measurement activation indication.

[0150] In summary, when the network device activates the L1 measurement, and the judgment basis of the network device is the first preset beam measurement result, the terminal device will perform two measurements, wherein the first measurement is the first preset beam measurement performed by the terminal device, and the second measurement is the L1 measurement performed by the terminal device. In the first measurement, the terminal device only measures the first preset beam; in the second measurement, only the measurement of the CIS-RS resource related to the first preset beam is performed. Not only the signaling is saved, but also the energy consumption of the terminal device is reduced.

[0151] In a possible embodiment, the first preset beam is an SSB. The SSB can be a reference signal in the CSI resource configuration. The CSI resource configuration can refer to the description in the above related concept.

[0152] In this embodiment, in one measurement, the terminal device only measures the SSB, and the terminal device sends the measurement result of the SSB to the network device. The network device judges whether to perform the second measurement. If the SSB measurement result meets the measurement activation condition, the network device sends the measurement activation indication to the terminal device, and the terminal device measures the beam resource related to the SSB.

[0153] Case three, the judgment basis of the network device is the received information related to the activated beam resource sent by another network device.

[0154] In a possible embodiment, the network device receives the information related to the activated beam resource sent by another network device; and sends the beam resource to the terminal device based on the information related to the activated beam resource.

[0155] The information related to the activated beam resource can include the indications in the above case two, which is not limited and described herein by the present application. The information related to the beam resource sent by the other network device is the information related to the beam resource activated by the other network device.

[0156] In a possible embodiment, under the inter CU, the network device receives the information related to the activated beam resource sent by another network device; and sends the beam resource to the terminal device based on the information related to the activated beam resource. The inter CU supports the interaction between the CUs.

[0157] Mode two, the terminal device activates the L1 measurement.

[0158] In the terminal device activation mode, in a possible embodiment, the first configuration information includes a measurement activation configuration, the measurement activation configuration is used for performing the L1 measurement related to the measurement activation configuration, and the first L1 measurement is not performed.

[0159] The measurement activation configuration is used for the first measurement of the terminal device, and the first measurement of the terminal device is the L1 measurement related to the measurement activation configuration. It should be noted that the first L1 measurement is not performed when the L1 measurement related to the measurement activation configuration is performed.

[0160] In a possible embodiment, the measurement activation information is a measurement activation condition, and the measurement activation condition is used to trigger the first L1 measurement.

[0161] The measurement activation condition is used for the terminal device to determine whether to perform the first L1 measurement. It can be understood that the measurement activation configuration is used for the first measurement, and the measurement activation condition is used for the terminal device to determine whether to perform the second measurement (the first L1 measurement) based on the first measurement result.

[0162] In a possible embodiment, the terminal device performs the first L1 measurement based on the first configuration information and the measurement activation information, including: if the first measurement result meets the measurement activation condition, the terminal device performs the first L1 measurement based on the beam measurement related information.

[0163] The first measurement result can be obtained by the terminal device performing the L1 measurement related to the measurement activation configuration based on the measurement activation configuration. That is, the first measurement result is the measurement result of the first measurement.

[0164] For example, the first configuration information includes the beam measurement related information and the measurement activation configuration, the beam measurement related information includes: beam 1, beam 2, beam 3, and the measurement activation configuration includes: beam 4. The terminal device performs measurement on the beam 4 to obtain the measurement result (the first measurement result) of the beam 4. If the measurement result of the beam 4 meets the measurement activation condition, the terminal device performs measurement on the beam 1, the beam 2, and the beam 3.

[0165] In a possible embodiment, the measurement activation configuration includes but is not limited to one or more of the following: L3 measurement configuration information, a first preset beam, a TCI state, a beam, and an SSB.

[0166] The measurement activation condition includes, but is not limited to, one or more of the following: the first preset beam / TCI state / beam-related measurement result is greater than a preset threshold (the first measurement result is greater than a preset threshold); or the quality of the first beam of the serving cell (the cell currently accessed by the terminal device) decreases by a certain threshold within a certain time; or the quality of the serving beam is less than a certain threshold; or the first preset beam is greater than a preset threshold, and the quality of the serving beam is less than a certain threshold. The measurement activation condition can be used to trigger measurement reporting. The first preset beam can be a preconfigured or predefined beam of the candidate cell, or the best beam of the candidate cell, or any beam of the candidate cell measured by the UE. The first beam of the serving cell can be a serving beam, the best beam in the serving cell, etc.

[0167] Specifically, the first measurement and the second measurement of the terminal device after the condition is met can refer to the introduction of case one and case two in mode one described above, which will not be repeated here.

[0168] In summary, the flow of mode two can be seen from FIG. 5B, and the network device sends the measurement activation condition of the second measurement to the terminal device, and the terminal device judges whether to activate the second measurement by itself. Since the second measurement is only performed when the condition is met, unnecessary beam resource measurement is avoided, and the energy consumption of the terminal device is saved.

[0169] The above describes two modes of activating measurement by the network device and the terminal device respectively. In addition to this, another embodiment of the present application is also involved, which triggers reporting or measurement by configuring a preset event. The mode of the preset event is further introduced as follows:

[0170] In a possible embodiment, the first configuration information can further include a preset event, a hysteresis factor, and an event threshold. The preset event provides a trigger reporting mechanism based on relative measurement results for the terminal device.

[0171] The preset event can be, for example, a preset event that the signal quality of the first beam is greater than a threshold if a hysteresis factor is configured.

[0172] In a possible embodiment, in addition to the preset event, the first configuration information can further include a first event and a second event. The first event is that the signal quality of the first beam minus the hysteresis factor is greater than the event threshold; and the second event is that the signal quality of the first beam plus the hysteresis factor is less than the event threshold. The condition for triggering reporting or measurement is at least one of the following: the preset event is met, the first event is met, the second event is met, and the second event is met within a certain time.

[0173] The reporting content includes at least one of the following: identification of one or more cells satisfying a triggering reporting or measurement condition; identification of one or more beams corresponding to the triggering reporting or measurement condition; signal quality of the beam; signal quality of the cell; or whether the beam satisfying the triggering reporting or measurement condition has a timing advance (TA).

[0174] For example, assuming that the signal quality of the first preset beam is -78 dB in the first time period, the hysteresis factor is 3 dB, and the event threshold is -80 dB, the signal quality of the first preset beam minus the hysteresis factor is -78 dB-3 dB=-81 dB, which is less than the event threshold (-81 dB<-80 dB); at the second time node, the signal quality of the first preset beam is -74 dB, the signal quality of the first preset beam minus the hysteresis factor is -74 dB-3 dB=-77 dB, which is greater than the event threshold (-77 dB>-80 dB), the preset event is satisfied at the second time node, and the preset event is reported to the network device at the second time node.

[0175] For example, assuming that the signal quality of the first preset beam is -78 dB in the first time period, the hysteresis factor is 3 dB, and the event threshold is -80 dB, the signal quality of the first preset beam plus the hysteresis factor is -78 dB+3 dB=-75 dB, which is greater than the event threshold (-75 dB>-80 dB); at the second time node, the signal quality of the first preset beam is -86 dB, the signal quality of the first preset beam plus the hysteresis factor is -86 dB+3 dB=-83 dB, which is less than the event threshold (-83 dB<-80 dB), the preset event is satisfied at the second time node, and the preset event is reported to the network device at the second time node.

[0176] The hardware structure of the network device and the terminal device described above is introduced below.

[0177] As shown in FIG. 6, FIG. 6 is a schematic diagram of the hardware structure of a communication apparatus provided in an embodiment of the present application. The communication apparatus 600 can be a terminal device or a network device in the above description.

[0178] For example, the communication apparatus 600 includes one or more processors 110, one or more memories 120, and one or more communication interfaces 130 (or a universal serial bus interface). The one or more memories 120 and the one or more processors 110 are coupled. The coupling in the embodiment of the present application is indirect coupling or communication connection between devices, units or modules, which can be electrical, mechanical or other forms, and is used for information interaction between devices, units or modules.

[0181] The memory 120 is configured to store program codes and data. In some embodiments, the memory 120 is a cache memory. The memory can hold program codes or data that have just been used or recycled by the processor 110. If the processor 110 needs to use the program codes or data again, it can be directly called from the memory 120. This avoids repeated access and reduces the waiting time of the processor 110, thus improving the efficiency of the system.

[0182] The processor 110 can operate in cooperation with the memory 120, or at least one of the one or more memories 120 can be included in the processor 110.

[0183] The communication interface 130 can optionally include a standard wired interface, a wireless interface (such as a mobile communication interface, etc.), and is controlled by the processor 110 to receive and transmit data; the communication interface 130 can optionally also enable data or signal communication between internal devices of the device. In the embodiments of the present application, the communication interface 130 is used to receive and transmit the first information to the fifth information mentioned in the above embodiments, etc.

[0184] It can be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the communication device 600. In other embodiments of the present application, the communication device 600 can include more or fewer components than those illustrated, or combine certain components, or split certain components, or different component arrangements. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0185] Please refer to FIG. 7, which is a structural schematic diagram of a communication device 700 according to an embodiment of the present application. The communication device shown in FIG. 7 can be a terminal device, a device in a terminal device, or a device that can be used in matching with a terminal device.
