Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular, to a method, device and storage medium for determining a reference signal of a candidate cell. Background Art

[0002] In the 3rd Generation Partnership Project (3GPP) radio access network (RAN), L1 / L2based inter-cell mobility (LTM) is proposed. Figure 1 As shown, the network device can maintain multiple candidate cells for the terminal device. As the terminal device moves, when it needs to switch cells, it can select a cell from the multiple candidate cells as a target cell and then switch to the target cell.

[0003] In LTM, in order to reduce the cell switching delay, the terminal device will perform L1 measurement on each candidate cell, and then determine whether the cell switching is needed at the moment based on the L1 measurement results of each candidate cell. However, if the terminal device performs L1 measurement on all the candidate cells configured for it every time, it will lead to problems such as large measurement time overhead and high complexity.

[0082] Exemplarily, a cell switching embodiment to which the present disclosure is applicable is introduced.

[0083] See also Figure 2 FIG. 1 is a schematic diagram of a cell switching process according to an exemplary embodiment. Figure 2 The process shown includes the following implementation steps:

[0084] S201. Pre-configuration of terminal equipment.

[0085] In one example, the network device may pre-configure / send the radio resource control (RRC) configuration parameters of the corresponding cell to the terminal device by, for example, a signaling message. After the terminal device receives the RRC configuration parameters of the corresponding cell, the pre-configuration of the corresponding cell may be implemented. For example, the RRC configuration parameters include a reference signal configuration, and the terminal device may perform beam measurement on the reference signal of the candidate cell indicated by the reference signal configuration based on the reference signal configuration.

[0086] S202. The terminal device performs downlink synchronization (DL Synchronization).

[0087] In one example, the terminal device may be synchronized based on downlink synchronization information sent by the network device. The downlink synchronization information includes, but is not limited to, a primary synchronization signal sequence, a secondary synchronization signal sequence, and a reference signal sequence sent by the network device, which is not limited in the present disclosure.

[0088] S203: The terminal device sends an L1 measurement report to the network device.

[0089] The L1 measurement report is used to determine whether to perform cell switching, wherein the L1 measurement involved in the present disclosure is also referred to as beam measurement, and the L1 measurement report is also referred to as a beam measurement result. The beam measurement result may include, but is not limited to, the L1-RSRP, L1-SINR, or other custom information of the cell. Among them, L1-RSRP is the reference signal receiving power (RSRP) sent by the corresponding cell beam, and L1-SINR is the signal to interference plus noise ratio (SINR) of the reference signal sent by the corresponding cell beam on the terminal device side. The cell switching here may refer to switching the cell where the terminal device currently resides (i.e., the serving cell, also referred to as the source cell, source cell) to another cell (i.e., the target cell). The target cell (target cell) is a cell selected from the candidate cells adjacent to the serving cell.

[0090] S204: The source cell decides whether to perform cell switching based on the L1 measurement report.

[0091] S205. The source cell sends a cell switch command to the terminal device.

[0092] The source cell of the network device can determine whether to perform cell switching based on the L1 measurement report. For example, when the L1 measurement result of a candidate cell is better than the current serving cell, or the L1 measurement result of a candidate cell is greater than a certain threshold, it can be determined that a cell switching is required, and the candidate cell can be used as the target cell. When it is determined that a cell switching is required, the source cell can send a cell switching command to the terminal device to trigger the terminal device to switch from the source cell to the target cell. The cell switching signaling is used to instruct / trigger the terminal device to switch from the source cell to the target cell.

[0093] S206. The terminal device accesses the target cell.

[0094] Accordingly, after receiving the cell switching signaling, the terminal device may switch the source cell to the target cell in response to the cell switching signaling.

Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 241 according to the brightness of the ambient light, and the proximity sensor may turn off the display panel 241 and / or the backlight when the terminal device is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the terminal device (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that the terminal device can also be configured with, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0110] The audio circuit 260, the speaker 261, and the microphone 262 can provide an audio interface between the user and the terminal device. The audio circuit 260 can transmit the received audio data to the speaker 261 after converting the received audio data into an electrical signal, which is converted into a sound signal for output; on the other hand, the microphone 262 converts the collected sound signal into an electrical signal, which is received by the audio circuit 260 and converted into audio data, and then the audio data is processed by the output processor 280, and then sent to another terminal device through the RF circuit 210, or the audio data is output to the memory 220 for further processing.

[0111] WiFi is a short-range wireless transmission technology. The terminal device can help users send and receive emails, browse web pages and access streaming media through the WiFi module 270, which provides users with wireless broadband Internet access. Figure 4 A WiFi module 270 is shown, but it is understandable that it is not a necessary component of the terminal device and can be omitted as needed without changing the essence of the invention.

[0112] The processor 280 is the control center of the terminal device 200. It uses various interfaces and lines to connect various parts of the entire terminal device. By running or executing software programs and / or modules stored in the memory 220, and calling data stored in the memory 220, it executes various functions of the terminal device and processes data, thereby monitoring the terminal device 200 as a whole. Optionally, the processor 280 may include one or more processing units; preferably, the processor 280 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 280.

[0113] The terminal device 200 also includes a power supply 290 (such as a battery) for supplying power to each component. Preferably, the power supply can be logically connected to the processor 280 through a power management system, so that the power management system can manage charging, discharging, and power consumption management. Although not shown, the terminal device 200 can also include devices such as a camera and a Bluetooth module, which will not be described in detail here.

[0114] By way of example, several possible application scenarios to which the present disclosure is applicable are first introduced below.

[0115] Please refer to FIG. 5(a) for a schematic diagram of an application scenario according to an exemplary embodiment. As shown in FIG. 5(a), the network device 100 pre-configures the reference signal of at least one candidate cell for the terminal device 200. In some embodiments, when the network device 100 configures the measurement report configuration (Reportconfig) for the terminal device 200, the measurement report configuration is associated with the reference signal of at least one candidate cell. The present disclosure does not limit the number of associated candidate cells, which can be determined according to actual conditions. The figure shows an example of associating reference signals of n candidate cells, but it does not constitute a limitation. n can be a positive integer determined according to actual conditions.

[0116] Further, the network device 100 may send the above measurement report configuration and the reference signals of each candidate cell associated therewith to the terminal device 200 through corresponding indication information or signaling. Accordingly, after receiving the above indication information / signaling, the terminal device 200 may perform beam measurement on the reference signals of each candidate cell associated with the measurement report configuration. Optionally, after receiving the above indication information / signaling, the terminal device 200 may not perform any beam measurement before receiving other indication information / signaling.

[0117] Please refer to FIG. 5( b ), which is a schematic diagram of another application scenario according to an exemplary embodiment. As shown in FIG. 5( b ), the network device 100 pre-configures the reference signal of at least one candidate cell for the terminal device 200. In some embodiments, when the network device 100 configures the measurement report configuration (Reportconfig) for the terminal device 200, the measurement report configuration is associated with the reference signal of at least one candidate cell. The network device 100 can dynamically change the above configuration association through corresponding indication information / signaling to indicate / send the reference signal of each candidate cell that the terminal device 200 needs to perform beam measurement to the terminal device 200.

[0118] In some embodiments, the network device 100 performs corresponding configuration for the serving cell and each candidate cell in the LTM in the RRC configuration parameters. As shown in the figure, the RRC configuration parameters include a serving cell configuration (serving cell config) and a candidate cell configuration (candidate cell config). The candidate cell configuration includes at least one candidate cell (candidate cell). The present disclosure does not limit the number of the above-mentioned candidate cells. The figure shows n candidate cells as an example, but it does not constitute a limitation. Each candidate cell may be associated with a corresponding reference signal or reference signal resource set (RSlistfor candidate cell). The above configuration may also include a measurement report configuration (Reportconfig) and a resource configuration (Resourceconfig). Among them, the measurement report configuration is used to indicate the result of the beam measurement performed by the reporting terminal device 200 on the candidate cell, such as the number of reported beams, the type and resource (which may be referred to as the reporting type and the reporting resource) to which the measurement report configuration belongs, or other custom information. The resource configuration contains / is associated with a reference signal or reference signal resource set of at least one candidate cell. The resource configuration is used to indicate the reference signal associated with the measurement report configuration, such as the reference signal of any candidate cell, etc., which is not limited in the present disclosure.

[0119] Correspondingly, after receiving the above indication information / signaling, the terminal device 200 can perform beam measurement on the reference signals of each candidate cell indicated by it that requires beam measurement.

[0120] Based on the above embodiments, in order to avoid the problems of long time expenditure and high complexity caused by the terminal device 200 performing L1 measurement on all candidate cells configured for it each time in LTM, the solution proposed in the present disclosure can dynamically indicate / select the reference signal of the candidate cell that needs to be measured for the terminal device, so as to reduce the time expenditure and complexity of the measurement.

[0121] See also Figure 6 FIG. 1 is a flow chart showing a method for determining a reference signal of a candidate cell according to an exemplary embodiment. Figure 6 The method shown is applied to a communication system, and the method comprises the following implementation steps:

[0122] S601: The network device 100 sends first indication information to the terminal device 200, where the first indication information is used to indicate the reference signal of the candidate cell for which the terminal device 200 needs to perform beam measurement. Accordingly, the terminal device 200 receives the first indication information.

[0123] The present disclosure does not limit the number of the above-mentioned candidate cells, which can be one or more, which can be determined according to actual conditions. The present disclosure does not limit the number and type of the above-mentioned reference signals. The reference signal refers to a reference signal that can perform beam measurement or reflect corresponding beam information, which may include but is not limited to any one or more of the following combinations: for example, a synchronization signal block (Synchronization Signal and PBCH block, SSB), a channel state information pilot signal (Channel State Information Reference Signal, CSI-RS) or other reference signals.

[0124] In one embodiment, the first indication information may be carried in any of the following types of signaling: downlink control information (DCI) signaling, or MAC control element (MAC CE) signaling. In summary, the present disclosure does not limit the method for sending the first indication information. In another embodiment, the present disclosure may carry the first indication information by introducing new signaling (for example, the network device may customize the selection of the corresponding dynamic signaling, which may be referred to as dynamic signaling or selection signaling) to indicate to the terminal device 200 the reference signal of the candidate cell for which beam measurement is required.

[0125] S602. The terminal device 200 performs beam measurement on the reference signal of the candidate cell indicated by the first indication information to obtain a beam measurement result.

[0126] After receiving the above-mentioned first indication information, the terminal device 200 may perform beam measurement on the reference signal of the corresponding candidate cell indicated by the first indication information based on the above-mentioned first indication information, and obtain the beam measurement result of the candidate cell. The beam measurement result is used to determine whether to switch the candidate cell, that is, to determine whether to switch the serving cell where the terminal device 200 is currently located to the candidate cell. For example, when the beam measurement result of the above-mentioned candidate cell is used to indicate that the signal quality strength of the candidate cell is high (such as greater than the preset strength), cell switching can be allowed, specifically, the serving cell where the terminal device 200 is currently located can be switched to the above-mentioned candidate cell.

[0127] The beam measurement result may also be referred to as a layer 1 (L1) measurement result, which may include but is not limited to, for example, L1-RSRP, L1-SINR, or other custom information of the candidate cell. For the relevant introduction of the above beam measurement results, please refer to the above Figure 2 The relevant introduction in the embodiments will not be repeated here.

[0128] By implementing the embodiment of the present disclosure, the network device 100 sends the first indication information, and the first indication information is used to indicate the reference signal of the candidate cell that the terminal device needs to perform beam measurement. Accordingly, the terminal device 200 receives the above-mentioned first indication information, and then can perform beam measurement on the reference signal of the candidate cell indicated by the first indication information to obtain the beam measurement result. In this way, the terminal device 200 only needs to perform beam measurement on the reference signal of the corresponding candidate cell indicated by the network device 100, instead of performing beam measurement on the reference signals of all candidate cells configured by it, which is conducive to saving the time overhead of beam measurement and reducing the measurement complexity.

[0129] See also Figure 7 FIG. 1 is a flow chart showing another method for determining a reference signal of a candidate cell according to an exemplary embodiment. Figure 7 The method shown is applied to the above communication system, and the method includes the following implementation steps:

[0130] S701. The network device 100 sends second indication information to the terminal device 200, where the second indication information is used to pre-configure a measurement report configuration for the terminal device and a reference signal of at least one candidate cell associated with the measurement report configuration.

[0131] S702. The terminal device 200 receives the second indication information sent by the network device 100.

[0132] In actual applications, before sending the above-mentioned first indication information, the network device 100 pre-configures the reference signal of at least one candidate cell for the terminal device 200, which may include the reference signal of the serving cell where the terminal device 200 is currently located. During implementation, when the network device 100 configures the corresponding measurement report configuration (Reportconfig) for the terminal device 200, the measurement report configuration may be associated with the reference signal of at least one candidate cell, that is, the measurement report configuration may be associated with the reference signal of the candidate cell that needs to perform beam measurement. Accordingly, the network device 100 may send a second indication information (or indication signaling) to the terminal device 200 to inform the network device 100 of the measurement report configuration pre-configured for the terminal device 200 and the reference signals of all candidate cells associated with the measurement report configuration.

[0133] Accordingly, after receiving the second indication information, the terminal device 200 can perform beam measurement on the reference signals of all candidate cells associated with the measurement report configuration indicated in the second indication information; or, it can wait for the network device 100 to send the first indication information, and before receiving the first indication information, it does not perform beam measurement on the reference signals of any candidate cells.

[0134] The following is combined with the above Figure 6 and Figure 7 The embodiment described above introduces some possible optional embodiments.

[0135] In different application scenarios, the specific indication method of the above-mentioned first indication information may be different. First, the specific indication method of the above-mentioned first indication information in the application scenario shown in Figure 5(a) is introduced. In this application scenario, the present disclosure can directly indicate the reference signal of the candidate cell that the terminal device 200 needs to perform beam measurement through the above-mentioned first indication information.

[0136] In some embodiments, if the measurement report configuration is associated with multiple resource configurations, the first indication information may include an identifier for indicating the measurement report configuration (which may also include an identifier of the measurement report configuration, Reportconfig ID), and state information (ResourceconfigstateID) corresponding to each resource configuration associated with the measurement report configuration. In this case, one resource configuration corresponds to one reference signal resource set (Resourceset), and one reference signal resource set includes a reference signal of a candidate cell. The present disclosure does not limit the number and type of the reference signal. For example, the reference signal resource set may include the SSB, CSI-RS or other reference signals of the candidate cell. The state information corresponding to the resource configuration is used to indicate whether to perform beam measurement on the reference signal resource set associated with the resource configuration (specifically, the reference signal of the candidate cell in the reference signal resource set).

[0137] The present disclosure does not limit the form of expression of the above-mentioned state information, which can be expressed in the form of numbers, letters, characters or a combination thereof, etc. For example, when the state information corresponding to the above-mentioned resource configuration is in the first state (such as 0 / 1), it can be used to indicate / indicate that the terminal device 200 needs to perform beam measurement on the reference signal resource set associated with the above-mentioned resource configuration; when the state information corresponding to the above-mentioned resource configuration is in the second state (such as 1 / 0), it can be used to indicate / indicate that the terminal device 200 does not need to perform beam measurement on the reference signal resource set associated with the above-mentioned resource configuration, etc.

[0138] The present disclosure does not limit the order of arrangement of the status information corresponding to each of the above-mentioned resource configurations. For example, the status information corresponding to each resource configuration may be arranged in a preset order (for example, in order from large to small) according to the identifiers (Resourceset ID) of the corresponding reference signal resource sets. The present disclosure also does not limit the number of status information corresponding to the above-mentioned resource configurations, which can be determined according to actual communication needs. For example, the above-mentioned first indication information may include the status information corresponding to each resource configuration associated with the above-mentioned measurement report configuration; or, it may also include the status information corresponding to the target resource configuration associated with the above-mentioned measurement report configuration and used to instruct the terminal device 200 to perform beam measurement, etc. That is to say, the above-mentioned first indication information only includes the status information corresponding to some resource configurations used to instruct the terminal device 200 to perform beam measurement, for example, only includes the status information corresponding to the resource configuration with a value of 0 / 1, etc. The present disclosure does not make too many restrictions and details on this.

[0139] In practical applications, the first indication information in this example can be carried in the first signaling for transmission. Figure 8FIG. 1 is a schematic diagram of a signaling format according to an exemplary embodiment. Figure 8 The signaling shown may include: a measurement report configuration field (Reportconfig ID) and at least one state information field (Resourceconfigstate ID, referred to as the state information field, and shown as T) of each resource configuration. Optionally, a reserved field (Reserved, R) may also be included. The present disclosure does not limit the number of the above-mentioned fields and their sizes (such as the number of bits or bytes occupied by the field), which can be determined according to actual conditions. The present disclosure is only illustrative but does not constitute a limitation. Among them, the above-mentioned measurement report configuration field is used to carry the identification of the above-mentioned measurement report configuration. The above-mentioned state information field is used to carry the state information corresponding to the corresponding resource configuration, and the resource configuration refers to the resource configuration managed by the above-mentioned measurement report configuration, that is, the resource configuration associated with the above-mentioned measurement report configuration. The present disclosure does not limit the number of the above-mentioned state information fields, which can be determined according to actual conditions. The figure shows N state information fields (TN) as an example, but it does not constitute a limitation. N is a positive integer determined according to actual conditions.

[0140] In some other embodiments, if the measurement report configuration is associated with multiple reference signal resource sets (Resourceset ID), the first indication information may include an identifier (Reportconfig ID) for indicating the measurement report configuration and state information (ResourcesetstateID) corresponding to each reference signal resource set associated with the measurement report configuration. Among them, a reference signal resource set includes a reference signal of a candidate cell. The state information corresponding to the reference signal resource set is used to indicate whether beam measurement is performed on the reference signal resource set (specifically, the reference signal of the candidate cell in the reference signal resource set). The introduction of the reference signal resource set can be referred to the relevant introduction in the previous embodiment, and will not be repeated here.

[0141] The present disclosure does not limit the form of expression of the above-mentioned status information, which can be expressed in the form of numbers, letters, characters or a combination thereof. For example, when the status information corresponding to the above-mentioned reference signal resource set is the third state (such as 0 / 1), it can be used to indicate / indicate that the terminal device 200 needs to perform beam measurement on the above-mentioned reference signal resource set; when the status information corresponding to the above-mentioned reference signal resource set is the fourth state (such as 1 / 0), it can be used to indicate / indicate that the terminal device 200 does not need to perform beam measurement on the above-mentioned reference signal resource set. Optionally, the present disclosure does not limit the arrangement order of the status information corresponding to the above-mentioned reference signal resource sets. For example, it can be arranged according to a preset order (for example, in order from large to small according to the identifier (Resourceset ID) of each reference signal resource set.

[0142] The present disclosure does not limit the amount of status information corresponding to the above-mentioned reference signal resource set, which can be determined according to actual communication needs. For example, the above-mentioned first indication information may include the status information corresponding to each reference signal resource set associated with the above-mentioned measurement report configuration; or, it may also include the status information corresponding to the target reference signal resource set associated with the above-mentioned measurement report configuration and used to instruct the terminal device 200 to perform beam measurement, etc., that is, the above-mentioned first indication information only includes the status information corresponding to some reference signal resource sets used to instruct the terminal device 200 to perform beam measurement, for example, only includes the status information corresponding to the reference signal resource set with a value of 0 / 1, etc., and the present disclosure does not make too many restrictions and details on this.

Fig. 9 FIG. 1 is a schematic diagram of another signaling format according to an exemplary embodiment. Fig. 9 The signaling shown may include: a measurement report configuration field (Reportconfig ID) and a state information field (ResourcesetstateID) of at least one reference signal resource set. Optionally, the signaling may also include a reserved field (Reserved, R). The present disclosure does not limit the number of the above fields and their sizes (such as the number of bits or bytes occupied by the field), which can be determined according to actual conditions. The present disclosure is only illustrative but does not constitute a limitation. Among them, the above measurement report configuration field is used to carry the identifier of the above measurement report configuration. The state information field of the above reference signal resource set is used to carry the state information corresponding to the above reference signal resource set. The reference signal resource set refers to the reference signal resource set managed by the above measurement report configuration, that is, the reference signal resource set associated with the above measurement report configuration. The present disclosure does not limit the number of the state information fields of the above reference signal resource set, which can be determined according to actual conditions. The figure shows the state information fields (ResourcesetstateID N) of N reference signal resource sets as an example, but it does not constitute a limitation. N is a positive integer determined according to actual conditions.

[0144] In other embodiments, if the resource configuration is associated with multiple reference signal resource sets, the first indication information may include an identifier of a resource configuration (Resourceconfig ID) and state information (ResourcesetstateID) corresponding to each reference signal resource set associated with the resource configuration. In this case, one resource configuration corresponds to at least one reference signal resource set, and one reference signal resource set includes a reference signal of a candidate cell. The present disclosure does not limit the number of resource configurations included in the first indication information. When there is at least one resource configuration, the first indication information includes an identifier of at least one resource configuration and state information corresponding to each reference signal resource set associated with each resource configuration. The present disclosure does not limit or elaborate on this. However, in actual applications, the first indication information usually includes an identifier of a resource configuration and state information corresponding to each reference signal resource set associated with the resource configuration. For the convenience of describing the present disclosure, this example is used to explain the relevant content below, but it does not constitute a limitation. The number of reference signal resource sets associated with each resource configuration can be determined according to actual conditions, and the present disclosure does not limit or elaborate on this. The state information corresponding to the reference signal resource set is used to indicate whether to perform beam measurement on the reference signal resource set (specifically, the reference signal of the candidate cell in the reference signal resource set). The introduction of the reference signal resource set and its state information can be referred to the relevant introduction in the previous embodiment, which will not be repeated here.

[0145] In practical applications, the first indication information in this example can be carried in the third signaling for transmission. Fig.10 FIG. 1 is a schematic diagram of another signaling format according to an exemplary embodiment. Fig.10The signaling shown may include: a resource configuration field (Resourceconfig ID) and a state information field (ResourcesetstateID) of at least one reference signal resource set associated with the resource configuration field. Optionally, the signaling may also include a reserved field (Reserved, R). The present disclosure does not limit the number of the above-mentioned fields and their sizes (such as the number of bits or bytes occupied by the field), which can be determined according to actual conditions. The present disclosure is only for illustration but does not constitute a limitation. Among them, the above-mentioned resource configuration field is used to carry the identifier of the corresponding resource configuration, and the state information field of the above-mentioned reference signal resource set is used to carry the state information corresponding to the reference signal resource set. The present disclosure does not limit the number of the above-mentioned resource configuration fields, which can be determined according to actual conditions. The figure shows one resource configuration field as an example, but it does not constitute a limitation. The present disclosure does not limit the number of state information fields of the reference signal resource set associated with the resource configuration field, which can be determined according to actual conditions. The figure shows the state information fields of N reference signal resource sets as an example, but it does not constitute a limitation. N is a positive integer determined according to actual conditions.

[0146] Next, the specific indication method of the first indication information in the application scenario shown in Figure 5(b) is introduced. In this application scenario, the present disclosure can dynamically change / indicate the reference signal of the candidate cell for which the terminal device 200 needs to perform beam measurement through the first indication information.

[0147] In some embodiments, when the measurement report configuration belongs to periodic reporting measurement, that is, when the reporting type corresponding to the measurement report configuration is periodic reporting, the indication method of the first indication information may have the following possible implementation modes:

When there is at least one resource configuration, the first indication information includes an identifier of at least one resource configuration and an identifier of at least one reference signal resource set associated with each resource configuration. The present disclosure does not limit or elaborate on this. However, in practical applications, the first indication information usually includes an identifier of a resource configuration and an identifier of at least one reference signal resource set associated with the resource configuration. For the convenience of describing the present disclosure, the following relevant contents are elaborated on this as an example, but it does not constitute a limitation.

For the purpose of description, the diagram takes 1 resource configuration field as an example, but it does not constitute a limitation. The above-mentioned reference signal resource set field is used to carry the identification of the corresponding reference signal resource set. The present disclosure does not limit the number of the above-mentioned reference signal resource set fields.

[0154] In a fourth embodiment, the first indication information may include an identifier of a resource configuration (Resourceconfig ID) and state information (ResourcesetstateID) corresponding to each reference signal resource set associated with the resource configuration. In this case, one resource configuration corresponds to at least one reference signal resource set, and one reference signal resource set includes a reference signal of a candidate cell. The present disclosure does not limit the number of resource configurations included in the first indication information. When there is at least one resource configuration, the first indication information includes an identifier of at least one resource configuration and state information corresponding to each reference signal resource set associated with each resource configuration. The present disclosure does not limit or elaborate on this. However, in actual applications, the first indication information usually includes an identifier of a resource configuration and state information corresponding to each reference signal resource set associated with the resource configuration. For the convenience of describing the present disclosure, this example is used to explain the relevant content below, but it does not constitute a limitation.

The state information corresponding to the reference signal resource set is used to indicate whether to perform beam measurement on the reference signal resource set (specifically, the reference signal of the candidate cell in the reference signal resource set).

Among them, a reference signal resource set includes a reference signal of a candidate cell. The state information corresponding to the reference signal resource set is used to indicate whether beam measurement is performed on the reference signal resource set (specifically, the reference signal of the candidate cell in the reference signal resource set). The introduction of the reference signal resource set and its state information may correspond to the relevant introduction in the previous embodiment, and will not be repeated here.

[0160] It should be noted that the above two implementation modes can be implemented separately or in combination. When they are implemented in combination, the above first indication information may include an identifier of the measurement report configuration (Reportconfig ID), an identifier of at least one reference signal resource set associated with the measurement report configuration (Resourceset ID), and state information (ResourcesetstateID) corresponding to each reference signal resource set associated with the measurement report configuration. The introduction of the above reference signal resource set and its state information can be referred to the relevant introduction in the previous embodiment, which will not be repeated here.

[0161] In the case where the measurement configuration report is a semi-static reporting measurement and is reported using a physical uplink control channel (PUCCH), that is, the reporting type corresponding to the measurement configuration report is a semi-static reporting and the reporting resource used is PUCCH, the first indication information may be carried in the eighth signaling, which is an activation signaling, such as MAC CE signaling or other activation signaling. Fig.13 FIG. 1 is a schematic diagram of another signaling format according to an exemplary embodiment. Fig.13The signaling format shown corresponds to the first implementation method described above, and the signaling may include: a measurement report configuration field (Reportconfig ID) and at least one reference signal resource set field (Resourceset ID). Optionally, a reserved field (Reserved, R) may also be included. The present disclosure does not limit the number of the above-mentioned fields and their sizes (such as the number of bits or bytes occupied by the field), which can be determined according to actual conditions. The present disclosure is only illustrative but does not constitute a limitation. Among them, the above-mentioned measurement report configuration field is used to carry the identifier of the above-mentioned measurement report configuration. The above-mentioned reference signal resource set field is used to carry the corresponding reference signal resource set associated with the measurement report configuration, which may specifically be the identifier of the reference signal resource set. The present disclosure does not limit the number of the above-mentioned reference signal resource set fields, which can be determined according to actual conditions. The figure shows N reference signal resource set fields (Resourceset ID N) as an example, but it does not constitute a limitation. N is a positive integer determined according to actual conditions. Regarding the signaling format corresponding to the above-mentioned second implementation method, please refer to the aforementioned Fig. 9 The relevant introduction of the second signaling in the embodiment will not be repeated here.

[0162] In the case where the measurement configuration report belongs to a semi-static reporting measurement and is reported using a physical uplink shared channel (PUSCH), that is, the reporting type corresponding to the measurement configuration report is a semi-static reporting and the reporting resource used is PUSCH, the first indication information may be carried in the downlink control information (DCI). In other words, the first indication information may be introduced in the triggered DCI to indicate the reference signal of the candidate cell for which the terminal device 200 needs to perform beam measurement.

[0163] In the case where the measurement configuration report belongs to non-periodic reporting measurement, that is, when the reporting type corresponding to the measurement report configuration is non-periodic reporting, the first indication information may also be carried in the DCI. That is to say, in order to support non-periodic reporting of measurement report configuration, the first indication information may be introduced in the triggered DCI to indicate the reference signal of the candidate cell for which the terminal device 200 needs to perform beam measurement. The indication method of the first indication information may refer to the relevant introduction in the above embodiment, which will not be repeated here.

[0164] It should be noted that, when the association relationship between the resource configuration and the reference signal resource set is clear, that is, when the network device 100 and the terminal device 200 have obtained one or more reference signal resource sets corresponding to each resource configuration in advance, the resource configuration and the reference signal resource set involved in the above-mentioned embodiments of the present disclosure can be used interchangeably according to actual conditions. For example, in the first embodiment of the application scenario shown in Figure 5(b), the above-mentioned first indication information may include an identifier of the measurement report configuration (Reportconfig ID) and an identifier of at least one resource configuration associated with the measurement report configuration, and one resource configuration corresponds to one reference signal resource set; that is, the above-mentioned first indication information is used to indicate the identifier of the measurement report configuration (Reportconfig ID) and at least one reference signal resource set associated with the measurement report configuration, etc., and the present disclosure does not make too many limitations and elaborations.

[0165] By implementing the embodiment of the present disclosure, the network device 100 sends a first indication information, and the first indication information is used to indicate the reference signal of the candidate cell that the terminal device needs to perform beam measurement. Accordingly, the terminal device 200 receives the above-mentioned first indication information, and can then perform beam measurement on the reference signal of the candidate cell indicated by the first indication information to obtain a beam measurement result. In this way, the terminal device 200 can directly perform beam measurement on the reference signal of the corresponding candidate cell indicated by the network device 100, rather than performing beam measurement on the reference signals of all candidate cells configured by it, which is conducive to saving the time overhead of beam measurement and reducing the measurement complexity; at the same time, it also solves the problems of large measurement time overhead and high complexity caused by the terminal device performing beam measurement on the reference signals of all candidate cells configured by it in the prior art.

[0166] In an exemplary embodiment, the present disclosure further provides a communication system, which may include a network device 100 and a terminal device 200. The network device 100 may execute the reference signal determination method for a candidate cell of the network device in the aforementioned embodiment of the present disclosure; the terminal device 200 may execute the reference signal determination method for a candidate cell of the terminal device in the aforementioned embodiment of the present disclosure.
