Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] As wireless communication systems operate at increasingly higher frequencies, the transmission path loss at higher frequencies increases, necessitating beamforming technology to create beams pointing in different directions, thereby improving coverage performance. In existing beam management processes, network devices obtain the quality of different beams by configuring and measuring reference signals. If network devices want to know beam information from terminal devices more frequently, they can configure periodic reference signals / reporting for the terminal devices, but this consumes significant uplink resources. If network devices want to conserve uplink resources, they can configure aperiodic reference signals / reporting for the terminal devices, triggering the terminal devices to report only when needed; however, the network devices may not be able to detect changes in beam quality in a timely manner.

[0003] Therefore, a process for triggering beam reporting by the terminal device has been discussed. Specifically, the terminal device measures the reference signal, and when certain defined events are met, the terminal device triggers a report. The current standard introduces the following conditions for the event to be met: the quality of the current "new beam" is better than that of the current beam and exceeds a threshold.

[0004] However, when there are multiple measurement results for a new beam or a current beam, it can lead to an excessive number of times the judgment event is satisfied, resulting in frequent reporting by the terminal device. Summary of the Invention

[0005] This application provides a communication method and related apparatus that, in the presence of multiple first reference signals, can determine whether an instance used to judge an event satisfies a third measurement value. That is, by determining the third measurement value used to judge an event instance from among the multiple measurement values ​​corresponding to multiple first reference signals, the multiple judgments of event instances caused by too many measurement values ​​of multiple first reference signals can be reduced, thereby reducing false triggering of events or frequent reporting by terminal devices.

[0006] This application provides a communication method, which is executed by a terminal device, or by a component (e.g., a processor, chip, or chip system) within the terminal device, or by a logic module or software capable of implementing all or part of the terminal device's functions. In this first aspect and its possible implementations, the method is described executed by a terminal device. The terminal device first receives a plurality of first reference signals and at least one second reference signal. Then, it determines a third reference signal and a fourth reference signal. Finally, it determines whether an instance used to judge an event satisfies the used third and fourth measurement values.

[0007] The third reference signal is the latest reference signal among the multiple first reference signals, and the fourth reference signal belongs to at least one second reference signal. The third measurement value includes the measurement value corresponding to the third reference signal, and the fourth measurement value includes the measurement value corresponding to the fourth reference signal.

[0008] It should be noted that "latest" can also be understood as latest, latest in the time domain, newest in the time domain, not used to judge event instances, etc., which will be described in the manual later and will not be elaborated here.

[0009] Based on the above scheme, after the terminal device receives multiple first reference signals, it can determine the third measurement value corresponding to the latest third reference signal among the multiple first reference signals and the fourth measurement value of the second reference signal, which are used to determine whether the event instance is satisfied. That is, by limiting it to "latest", the multiple judgments of event instances caused by multiple measurement values ​​of multiple reference signals in the prior art can be reduced, thereby reducing false triggering of events.

[0010] Optionally, in one possible implementation of the first aspect, the transmission period of the plurality of first reference signals is different from the transmission period of at least one second reference signal.

[0011] In this possible implementation, the solution provided in this application can determine the measurement value used to judge whether the event instance meets the requirements when the transmission periods of the two types of reference signals are different. This can reduce the multiple judgments of event instances caused by multiple measurement values ​​of multiple reference signals in the prior art, and reduce the false triggering of events.

[0012] Optionally, in one possible implementation of the first aspect, the number of the at least one second reference signal is multiple, and the fourth measurement value is the measurement value corresponding to the latest second reference signal among the multiple second reference signals.

[0013] In this possible implementation, the third measurement value is the measurement value of the latest first reference signal among a plurality of first reference signals. The fourth measurement value is the measurement value of the latest second reference signal among a plurality of second reference signals. By limiting both types of reference signals to the latest measurement value, multiple judgments of event instances caused by one type of reference signal involving multiple measurement values ​​are reduced, thereby reducing false triggering of events.

[0014] Optionally, in one possible implementation of the first aspect, the aforementioned third and fourth measurements are used only to determine whether a single instance of the event satisfies the condition.

[0015] In this possible implementation, by limiting the measurement value to be used only for one event instance judgment, the number of times a single measurement value is used for multiple event instance judgments in the prior art can be reduced, thereby reducing the false triggering of events caused by multiple instance judgments.

[0016] Alternatively, in one possible implementation of the first aspect, the aforementioned multiple comparisons of the third measurement value are regarded as one instance of an event, or the multiple comparisons of the fourth measurement value are regarded as one instance of an event.

[0017] In this possible implementation, even if the measured value is compared multiple times, it can still be regarded as one instance. In this way, even if the measured value is compared multiple times, it will not lead to multiple instance judgments of the event, thereby reducing the false triggering of events caused by multiple instance judgments.

[0018] Optionally, in one possible implementation of the first aspect, the evaluation period of the aforementioned event is the larger of the first transmission period of the plurality of first reference signals and the second transmission period of at least one second reference signal.

[0019] In this possible implementation, by limiting the evaluation period of the event to the larger of the transmission periods of the two types of reference signals, the excessive number of event evaluations caused by the smaller transmission period of a certain type of reference signal can be reduced, thereby reducing the energy consumption of the terminal device in evaluating the event.

[0020] Optionally, in one possible implementation of the first aspect, the number of times an instance of the event within the aforementioned evaluation period satisfies the condition is less than or equal to 1.

[0021] In this possible implementation, by limiting the number of times an event instance satisfies the condition within an evaluation period to no more than 1, the process of judging multiple instances within an evaluation period is reduced, and the number of instances judged by repeated measurements is also reduced.

[0022] Optionally, in one possible implementation of the first aspect, the second transmission period of at least one second reference signal is greater than the first transmission period of the plurality of first reference signals, and the second transmission period serves as the measurement period of the plurality of first reference signals.

[0023] In this possible implementation, the transmission period of the larger of the two types of reference signals is used as the measurement period of the smaller reference signal to reduce the frequent measurement of the smaller reference signal. This not only reduces the measurement power consumption of the terminal device, but also facilitates the frequent reporting caused by the large number of measurement values ​​of a certain type of reference signal when judging event instances.

[0024] Optionally, in one possible implementation of the first aspect, the terminal device may further receive a plurality of fifth reference signals, the period of the plurality of fifth reference signals being a third transmission period, the third measurement value including the measurement value corresponding to the third reference signal and the measurement value of the plurality of fifth reference signals, the evaluation period of the event or the measurement period of the measurement value being the larger of the fourth transmission period and the second transmission period, the fourth transmission period including any one of the following: the largest transmission period of the first transmission period and the third transmission period, the smallest transmission period of the first transmission period and the third transmission period, and the average period of the first transmission period and the third transmission period.

[0025] In this possible implementation, when there are multiple reference signals of a certain type, the transmission periods of the reference signals of the same type can be compared first. Then, the comparison result of the reference signals of the same type can be compared with the transmission period of another type of reference signal to determine the evaluation period of the event or the measurement period of each reference signal. For example, the larger of the fourth transmission period obtained after comparing the reference signals of the same type and the second transmission period of another type of reference signal can be taken as the evaluation period of the event or the measurement period of the reference signal with the smaller transmission period. This can reduce the frequent measurement and evaluation of reference signals with smaller transmission periods.

[0026] Optionally, in one possible implementation of the first aspect, the terminal device may further receive a plurality of sixth reference signals, the period of which is a fifth transmission period, the fourth measurement value includes the measurement value corresponding to the fourth reference signal and the measurement value corresponding to the plurality of sixth reference signals, and the evaluation period of the event or the measurement period of the measurement value is the larger of the sixth transmission period and the first transmission period; the sixth transmission period includes any one of the following: the largest transmission period of the second transmission period and the fifth transmission period, the smallest transmission period of the second transmission period and the fifth transmission period, and the average period of the second transmission period and the fifth transmission period.

[0027] In this possible implementation, when there are multiple reference signals of a certain type, the transmission periods of the reference signals of the same type can be compared first. Then, the comparison result of the reference signals of the same type can be compared with the transmission period of another type of reference signal to determine the evaluation period of the event or the measurement period of each reference signal. For example, the larger of the sixth transmission period obtained after comparing the reference signals of the same type and the first transmission period of another type of reference signal can be taken as the evaluation period of the event or the measurement period of the reference signal with the smaller transmission period. This can reduce the frequent measurement and evaluation of reference signals with smaller transmission periods.

[0028] Optionally, in one possible implementation of the first aspect, the time-domain symbol interval between the third reference signal corresponding to the third measurement value and the fourth reference signal corresponding to the fourth measurement value is less than a preset interval. For example, it can be the closest time-domain interval.

[0029] In this possible implementation, by limiting the time-domain interval between the two measurements used to determine the event, a more ideal measurement value can be determined, which can improve the accuracy and latency of subsequent instance judgments.

[0030] Optionally, in one possible implementation of the first aspect, the at least one second reference signal is a reference signal configured by the network device, and the plurality of first reference signals include at least one of the following: a reference signal associated with the active transmission configuration indicator (TCI) of the physical downlink channel, a quasi-co-located (QCL) source reference signal of the active TCI of the physical downlink channel, an SSB with a QCL relationship to the active TCI of the physical downlink channel, a reference signal associated with the beam / TCI currently used by the terminal device, etc. The physical downlink channel may include at least one of the following: a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), etc. Or,

[0031] The multiple first reference signals are reference signals configured for network devices, and at least one second reference signal includes at least one of the following: a reference signal associated with the active TCI of the physical downlink channel, a QCL source reference signal of the active TCI of the physical downlink channel, an SSB that has a QCL relationship with the active TCI of the physical downlink channel, and a reference signal associated with the beam / TCI currently used by the terminal device.

[0032] In this possible implementation, the second reference signal can be understood as a new beam, and the first reference signal can be understood as a current beam. Alternatively, the first reference signal can be understood as a new beam, and the second reference signal can be understood as a current beam. That is, the solution provided in this application is applicable not only to scenarios with multiple new beams, but also to scenarios with multiple current beams.

[0033] Optionally, in one possible implementation of the first aspect, the aforementioned terminal device may also report a measurement report, which is used for beam switching, provided that the instance is satisfied.

[0034] In this possible implementation, the terminal device reports a measurement report when it determines that the instance meets the requirements. This allows network devices to switch to a higher-performance beam based on the measurement report, thereby improving data transmission performance.

[0035] Optionally, in one possible implementation of the first aspect, the terminal device may also receive first information, which is used to indicate the larger of the first transmission period of the first reference signal and the transmission period of at least one second reference signal as the measurement period of the measured value and / or the evaluation period of the event.

[0036] In this possible implementation, the terminal device can determine the measurement period and / or the event evaluation period through the first information, and use the larger of the two types of reference signal transmission periods as the measurement period or evaluation period, thereby reducing the measurement energy consumption of the terminal device or the false triggering of events due to a large number of measurement values.

[0037] Optionally, in one possible implementation of the first aspect, the number of at least one second reference signal is less than the number of at least one first reference signal, and the number of fourth measurements is multiple. The filtered values ​​of the multiple fourth measurements, along with the third measurement value, are used to determine whether a single instance of the event is satisfied.

[0038] In this possible implementation, when there are a large number of reference signals of a certain type, the terminal device can also use filtering to reduce the number of times an event instance is judged, thereby reducing the probability of false triggering of the event.

[0039] Optionally, in one possible implementation of the first aspect, the terminal device may also receive second information, which is used to indicate whether the filtered value of multiple fourth measurements and the third measurement value are satisfied to determine an instance of the event.

[0040] In this possible implementation, the terminal device can determine whether to use filtering to determine the measurement value by receiving the second information, and by using filtering, the number of times the event instance is judged is reduced, thereby reducing the probability of false triggering of the event.

[0041] Optionally, in one possible implementation of the first aspect, the judgment condition satisfied by the above-mentioned event includes at least one of the following: the difference between the measured value of the third reference signal and the measured value of the fourth reference signal is greater than or equal to a first threshold, and the first count is greater than or equal to a second threshold; the first count is the number of times the difference between the measured value of the third reference signal and the measured value of the fourth reference signal is greater than or equal to the third threshold.

[0042] This possible implementation provides multiple ways to determine if an event meets certain conditions. Terminal devices can choose the appropriate determination method based on actual needs or network devices, thereby improving the flexibility of event determination.

[0043] A second aspect of this application provides a communication method, which is executed by a network device, or by a component (e.g., a processor, chip, or chip system) within the network device, or by a logic module or software capable of implementing all or part of the functions of the network device. In this second aspect and its possible implementations, the method is described as being executed by a network device. The network device transmits a plurality of first reference signals and at least one second reference signal; and receives a measurement report.

[0044] In this system, multiple first reference signals are used to determine a third reference signal, and at least one second reference signal is used to determine a fourth reference signal. The third reference signal is the latest of the multiple first reference signals, and the fourth reference signal belongs to at least one second reference signal. The measurement report is determined based on the third and fourth measured values, where the third measured value is the measurement value corresponding to the third reference signal, and the fourth measured value includes the measurement value corresponding to the fourth reference signal.

[0045] In this possible implementation, the third measurement value corresponding to the latest third reference signal among the multiple first reference signals sent by the network device, along with the fourth measurement value of the second reference signal, is used to determine whether an event instance satisfies the condition. That is, by using the "latest" constraint, the multiple judgments of event instances caused by multiple measurement values ​​of multiple reference signals in the prior art can be reduced, thus reducing false triggering of events.

[0046] Optionally, in one possible implementation of the second aspect, the transmission period of the plurality of first reference signals is different from the transmission period of at least one second reference signal.

[0047] In this possible implementation, the solution provided in this application can determine the measurement value used to determine whether an event instance is satisfied when the transmission periods of the two types of reference signals are different. This can reduce the multiple judgments of event instances caused by multiple measurement values ​​of multiple reference signals in the prior art, and reduce the false triggering of events.

[0048] Optionally, in one possible implementation of the second aspect, the number of the at least one second reference signal is multiple, and the fourth measurement value is the measurement value corresponding to the latest second reference signal among the multiple second reference signals.

[0049] In this possible implementation, the third measurement value is the measurement value of the latest first reference signal among a plurality of first reference signals. The fourth measurement value is the measurement value of the latest second reference signal among a plurality of second reference signals. By limiting both types of reference signals to the latest measurement value, multiple judgments of event instances caused by one type of reference signal involving multiple measurement values ​​are reduced, thereby reducing false triggering of events.

[0050] Optionally, in one possible implementation of the second aspect, the aforementioned third and fourth measurements are used only to determine whether a single instance of the event satisfies the condition.

[0051] In this possible implementation, by limiting the measurement value to be used only for one event instance judgment, the number of times a single measurement value is used for multiple event instance judgments in the prior art can be reduced, thereby reducing the false triggering of events caused by multiple instance judgments.

[0052] Alternatively, in one possible implementation of the second aspect, the aforementioned multiple comparisons of the third measurement value are regarded as one instance of an event, or the multiple comparisons of the fourth measurement value are regarded as one instance of an event.

[0053] In this possible implementation, even if the measured value is compared multiple times, it can still be regarded as one instance. In this way, even if the measured value is compared multiple times, it will not lead to multiple instance judgments of the event, thereby reducing the false triggering of events caused by multiple instance judgments.

[0054] Optionally, in one possible implementation of the second aspect, the evaluation period of the aforementioned event is the larger of the first transmission period of the plurality of first reference signals and the second transmission period of at least one second reference signal.

[0055] In this possible implementation, by limiting the evaluation period of the event to the larger of the transmission periods of the two types of reference signals, the excessive number of event evaluations caused by the smaller transmission period of a certain type of reference signal can be reduced, thereby reducing the energy consumption of the terminal device in evaluating the event.

[0056] Alternatively, in one possible implementation of the second aspect, the number of times an instance of the event within the aforementioned evaluation period satisfies the condition is less than or equal to 1.

[0057] In this possible implementation, by limiting the number of times an event instance satisfies the condition within an evaluation period to no more than 1, the process of judging multiple instances within an evaluation period is reduced, and the number of instances judged by repeated measurements is also reduced.

[0058] Optionally, in one possible implementation of the second aspect, the second transmission period of at least one second reference signal is greater than the first transmission period of the plurality of first reference signals, and the second transmission period serves as the measurement period of the plurality of first reference signals.

[0059] In this possible implementation, the transmission period of the larger of the two types of reference signals is used as the measurement period of the smaller reference signal to reduce the frequent measurement of the smaller reference signal. This not only reduces the measurement power consumption of the terminal device, but also facilitates the frequent reporting caused by the large number of measurement values ​​of a certain type of reference signal when judging event instances.

[0060] Optionally, in one possible implementation of the second aspect, the network device may also send multiple fifth reference signals, the period of the multiple fifth reference signals being a third transmission period, the third measurement value corresponding to multiple fifth reference signals and multiple first reference signals, and the evaluation period of the event being the larger of the fourth transmission period and the second transmission period.

[0061] The fourth transmission cycle includes any one of the following: the largest transmission cycle between the first and third transmission cycles, the smallest transmission cycle between the first and third transmission cycles, and the average cycle between the first and third transmission cycles.

[0062] In this possible implementation, when there are multiple reference signals of a certain type, the transmission periods of the reference signals of the same type can be compared first. Then, the comparison result of the reference signals of the same type can be compared with the transmission period of another type of reference signal to determine the evaluation period of the event or the measurement period of each reference signal. For example, the larger of the fourth transmission period obtained after comparing the reference signals of the same type and the second transmission period of another type of reference signal can be taken as the evaluation period of the event or the measurement period of the reference signal with the smaller transmission period. This can reduce the frequent measurement and evaluation of reference signals with smaller transmission periods.

[0064] The sixth transmission cycle includes any one of the following: the largest transmission cycle between the second and fifth transmission cycles, the smallest transmission cycle between the second and fifth transmission cycles, and the average cycle between the second and fifth transmission cycles.

[0065] In this possible implementation, when there are multiple reference signals of a certain type, the transmission periods of the reference signals of the same type can be compared first. Then, the comparison result of the reference signals of the same type can be compared with the transmission period of another type of reference signal to determine the evaluation period of the event or the measurement period of each reference signal. For example, the larger of the sixth transmission period obtained after comparing the reference signals of the same type and the first transmission period of another type of reference signal can be taken as the evaluation period of the event or the measurement period of the reference signal with the smaller transmission period. This can reduce the frequent measurement and evaluation of reference signals with smaller transmission periods.

[0066] Optionally, in one possible implementation of the second aspect, the time-domain symbol interval between the third reference signal corresponding to the third measurement value and the fourth reference signal corresponding to the fourth measurement value is less than a preset interval.

[0067] In this possible implementation, by limiting the time-domain interval between the two measurements used to determine the event, a more ideal measurement value can be determined, which can improve the accuracy and latency of subsequent instance judgments.

[0152] To facilitate understanding of the technical solutions of the embodiments of this application, a brief introduction of the relevant terms in this application is given below.

[0153] 1. Beam

[0154] In the NR protocol, beams can be referred to as spatial domain filters, spatial filters, spatial domain parameters, spatial parameters, spatial domain settings, spatial settings, quasi-colocation (QCL) information, QCL assumptions, or QCL indications, etc. Beams can be indicated by transmission configuration indicator state (TCI-state) parameters or spatial relation parameters. Therefore, in this application, beams can be replaced by spatial domain filters, spatial filters, spatial parameters, spatial parameters, spatial settings, spatial settings, quasi-colocation (QCL) information, QCL assumptions, QCL indications, TCI-states (including uplink (UL) TCI state and downlink TCI state), or spatial relations, etc. These terms are also equivalent to each other. The term "beam" can be replaced with other beam terms, which are not limited herein.

[0155] The beam used to transmit signals can be called a transmission beam (Tx beam), spatial domain transmission filter, spatial transmission filter, spatial domain transmission parameter, spatial transmission parameter, spatial domain transmission setting, or spatial transmission setting. The downlink transmission beam can be indicated by TCI-state. The uplink transmission beam can be indicated by any of the following: spatial relation, TCI-state, or SRS resource (indicating the transmission beam using that SRS). Therefore, the uplink transmission beam can also be replaced by an SRS resource.

[0156] The beam used to receive signals can be called a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial domain reception setting, or a spatial reception setting.

[0157] For example, a transmit beam can refer to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while a receive beam can refer to the distribution of signal strength in different directions in space of a wireless signal received from an antenna. It is understood that a beam can be associated with one or more physical antennas, corresponding to one or more antenna ports. For example, for CSI-RS resources used for beam management, a CSI-RS resource can contain one or more ports, and one CSI-RS resource corresponds to one beam; that is, all ports within the same CSI-RS resource correspond to the same beam.

[0158] When using low- or mid-frequency bands, the transmitting end can transmit signals omnidirectionally or over a wide angle. When using high-frequency bands, thanks to the smaller carrier wavelength of high-frequency communication systems, antenna arrays consisting of numerous antenna elements can be arranged at both the transmitting and receiving ends. The transmitting end transmits signals with specific beamforming weights, creating a spatially directional beam. Simultaneously, the receiving end uses an antenna array with specific beamforming weights to receive the signal. This helps improve the received signal power at the receiving end and counteract path loss.

[0159] Beams are generally associated with resources. For example, during beam measurement, network devices use different beams to transmit signals on different resources. Terminal devices provide feedback on the signal quality measured for different resources, allowing the network device to determine the quality of the corresponding beam. During data transmission, beam information is also indicated through its corresponding resource. For instance, network devices use the TCI field in downlink control information (DCI) to indicate the physical downlink shared channel (PDSCH) beam information of the terminal device.

[0160] Optionally, a beam may include one or more antenna ports for transmitting data channels, control channels, and probe signals, etc. One or more antenna ports forming a beam can also be considered as a set of antenna ports.

[0161] A beam is a communication resource. A beam can be wide, narrow, or other types of beams, and the technology used to form a beam can be beamforming technology or other techniques. Beamforming technology can specifically be digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered different resources.

[0162] 2. Channel State Information (CSI)

[0163] CSI is used to evaluate or describe the characteristics of a communication channel, which may include, for example, channel gain, phase information, multipath fading information, and interference information.

[0164] CSI reporting methods can include periodic CSI reporting (P-CSI), semi-persistent CSI reporting (SP-CSI), and aperiodic CSI reporting (AP-CSI).

[0165] (1) The process of periodic CSI reporting includes: network devices configuring terminal devices to perform periodic CSI reporting via higher-layer signaling (such as RRC signaling); terminal devices performing channel and interference measurements based on periodic channel state information reference signal (CSI-RS) resources; and reporting CSI on the physical uplink control channel (PUCCH) at fixed time intervals. In periodic CSI reporting, the channel measurement resource (CMR) and interference measurement resource (IMR) used for measurement are both periodic. Specific periodicity and resource mapping parameters can be configured by the network devices for the terminal devices via RRC signaling. Furthermore, the CSI reporting period and the PUCCH resources used for reporting are also configured by the network devices for the terminal devices via RRC signaling.

[0166] (2) The semi-persistent CSI reporting process includes: When a terminal device is configured to use semi-persistent CSI reporting, the terminal device only starts CSI reporting when it receives downlink signaling from the network to instruct it to start CSI reporting, and only ends CSI reporting after receiving downlink signaling to stop CSI reporting. Between these two downlink signaling transmission times, the terminal device performs periodic CSI measurements and reports. The CMR and IMR used in semi-persistent CSI reporting can be periodic or semi-persistent. When the terminal device uses semi-persistent CSI reporting, it can report on PUCCH resources. The network device can activate and deactivate semi-persistent CSI reporting through downlink higher-layer signaling (e.g., MAC CE signaling). When the terminal device uses semi-persistent CSI reporting, it can also report on physical uplink shared channel (PUSCH) resources. The network device can activate and deactivate semi-persistent CSI reporting through physical layer downlink control information (DCI). Regardless of whether SP CSI measurement is performed using PUCCH or PUSCH, the measurement parameters such as measurement quantity and measurement bandwidth can be configured by the network device to the terminal device via RRC signaling.

[0167] (3) The non-periodic CSI reporting and measurement process includes:

[0168] The network device first semi-statically configures multiple CSI reporting parameters for the terminal device via downlink RRC signaling. For example, the network device triggers one or more CSI reporting configuration parameters to the terminal device via DCI. The terminal device performs CSI measurements according to the CSI reporting configuration parameters and reports the CSI measurement results using PUSCH resources. It is important to note that although aperiodic CSI reporting, like semi-persistent CSI reporting, requires network device triggering, aperiodic CSI reporting does not require deactivation after activation via DCI and only performs one measurement and report. The CMR and IMR used in aperiodic CSI reporting can be periodic, semi-persistent, or aperiodic.

[0169] It should be noted that in the three CSI reporting schemes mentioned above, the configuration parameters required during the CSI reporting process can be configured by the network device to the terminal device via RRC signaling. These configuration parameters may include the reporting quantity and reporting bandwidth. The reporting quantity may include one or more of the following: rank indicator (RI), channel quality indicator (CQI), precoding matrix indicator (PMI), reference signal receiving power (RSRP), and CSI-RS resource indicator (CRI). In NR systems, network devices can fulfill different measurement requirements through the configuration parameters of CSI measurements.

[0170] Network devices can configure CSI resource configuration parameters for terminal devices via higher-layer signaling, such as RRC signaling, to indicate the resources used for measurement and reporting. For example, the csi-resourceConfig field in RRC signaling can be used to configure the resources used for measurement and reporting for the terminal device. CSI resource configuration parameters can include 1 to 3 CSI-RS resource settings.

[0171] In one example, when the CSI resource configuration parameters include one CSI-RS resource setting, this CSI-RS resource setting is used to implement beam measurement, that is, to calculate the Layer 1 Reference Signal Received Power (L1-RSRP).

[0172] In another example, when the CSI resource configuration parameters include two CSI-RS resource settings, one CSI-RS resource setting contains a set of non-zero power channel state information-reference signal resources (NZP CSI-RS resource set). The NZP CSI-RS resource set can be configured via the higher-level parameter NZP-CSI-RS-ResourceSet. The network device can indicate to the terminal device the NZP CSI-RS resource set used for channel measurement within the set of NZP CSI-RS resource sets, allowing the terminal device to perform channel measurements based on the NZP CSI-RS resource set indicated by the network device. The other CSI-RS resource setting contains either an NZP CSI-RS resource set or a CSI-Interference Measurement (CSI-IM) resource set. Further, the terminal device performs interference measurements on either the NZP CSI-RS resource set or the CSI-IM resource set. The CSI-IM resource set can be configured to the terminal device by the network device via the higher-level parameter CSI-IM-ResourceSet.

[0173] It should be noted that: A single NZP CSI-RS resource set for channel measurement, as indicated by the network device in the CSI-RS resource setting, can contain n NZP CSI-RS resources. When interference measurement is based on NZP CSI-RS, n = 1; while when interference measurement is based on CSI-IM, n ≥ 1 and n is an integer. When n ≥ 1, the CSI-IM resource set will also contain the same number of CSI-IM resources, corresponding one-to-one with the n NZP CSI-RS resources in the NZP CSI-RS resource set. The terminal device will select one NZP CSI-RS resource from the n NZP CSI-RS resources, for example, the Xth NZP CSI-RS resource, and perform measurements on this NZP CSI-RS resource and the corresponding CSI-IM resource, reporting the CSI measurement results. The CSI measurement results include the reporting quantity indicated by the network device through higher-layer signaling (reportQuantity, included in the CSI reporting configuration parameter CSI-ReportConfig). When reporting CSI measurement results on the terminal device, the corresponding NZP CSI-RS resource indicator (CRI) will also be reported, which is used to indicate X.

[0174] In another example, when the CSI resource configuration parameters include three CSI-RS resource settings, the first CSI-RS resource setting contains a set of NZP CSI-RS resource sets. The network device can indicate to the terminal device the NZP CSI-RS resource set used for channel measurement within this set, allowing the terminal device to perform channel measurements based on the NZP CSI-RS resource set indicated by the network device. The second CSI-RS resource setting contains a set of NZP CSI-RS resource sets; the third CSI-RS resource setting contains a CSI-IM resource set. The terminal device performs interference measurements based on the second and third resources, the difference being that the terminal device will perform inter-user interference measurements based on the NZP CSI-RS resource set included in the second CSI-RS resource setting, and inter-cell interference measurements based on the CSI-IM resource set included in the third CSI-RS resource setting.

[0175] 3. CSI-RS Configuration

[0176] In NR systems, channel measurements are performed on the NZP CSI-RS resource setting. The time-domain transmission behavior of NZP CSI-RS can be periodic (P-CSI-RS), semi-persistent (SP-CSI-RS), or aperiodic (AP-CSI-RS). For each CSI reporting, one CSI-RS resource setting can be configured for channel measurement. This CSI-RS resource setting will be configured with a type (P / SP / AP-CSI-RS), which is used to indicate time-domain transmission behavior. Each CSI-RS resource setting can contain m CSI-RS resource sets. When the type of the CSI-RS resource setting is P / SP-CSI-RS, m = 1; when the type of the CSI-RS resource setting is AP-CSI-RS, m ≥ 1. When m ≥ 1, for a specific CSI measurement report, the network device will select one CSI-RS resource set from m ≥ 1 CSI-RS resource sets for the terminal device to associate with this specific CSI measurement and report.

[0177] 4. Terminal equipment

[0178] The terminal device can be a wireless terminal device capable of receiving network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connectivity, or other processing device connected to a wireless modem.

[0179] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station (MS), remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc. Terminal equipment can also be wearable devices and next-generation communication systems, such as terminal equipment in 5G communication networks and future communication networks, or terminal equipment in future evolved public land mobile networks (PLMNs).

[0180] 5. Network equipment

[0181] Network devices can be devices within a wireless network. For example, a network device can be a radio access network (RAN) node (or device) that connects terminal devices to the wireless network; it can also be called a base station. Currently, some examples of RAN devices include: next-generation Node B (gNodeB), transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved Node B, or home Node B (HNB)), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP) in a network architecture. Additionally, in a network structure, network devices can include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN devices that include both CU and DU nodes.

[0182] Specifically, network devices can send configuration information to terminal devices (e.g., carried in scheduling messages and / or indication messages). The terminal devices then configure their networks based on this information, aligning the network configurations of the network devices and terminal devices. Alternatively, network configurations can be pre-set in both the network devices and the terminal devices to achieve alignment. In essence, "alignment" means that when there are interactive messages between the network devices and terminal devices, their understanding of the carrier frequency for sending and receiving interactive messages, the determination of the interactive message type, the meaning of the fields carried in the interactive messages, or other configurations of the interactive messages is consistent.

[0183] Furthermore, in other possible cases, the network device can be any other device that provides wireless communication functionality to the terminal device. The embodiments of this application do not limit the specific technology or device form used in the network device. For ease of description, the embodiments of this application are not limited.

[0184] Network equipment may also include core network equipment, such as access and mobility management function (AMF), user plane function (UPF), or session management function (SMF).

[0185] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the function of the network device is used to describe the technical solutions provided in this application embodiment.

[0186] 6. Configuration and Pre-configuration

[0187] This application uses both configuration and pre-configuration. Configuration refers to the network device / server sending configuration information or parameter values ​​to the terminal device via messages or signaling, so that the terminal device can determine communication parameters or resources for transmission based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or values ​​pre-negotiated between the network device / server and the terminal device, parameter information or values ​​specified by standard protocols for use by the base station / network device or terminal device, or parameter information or values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0188] Furthermore, these values ​​and parameters can be changed or updated.

[0189] 7. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent the following situations: A exists alone, B exists alone, and A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and / or C" can represent: A exists alone, B exists alone, C exists alone, A and B exist simultaneously, A and C exist simultaneously, B and C exist simultaneously, and A, B and C exist simultaneously. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0190] 8. In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission via the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY via the air interface by other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface; furthermore, "send" can also be understood as the baseband part inside the device outputting information to the radio frequency part, and "receive" can also be understood as the radio frequency part inside the device receiving the information output by the baseband part.

[0191] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0192] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0193] In the embodiments of this application, transmission includes sending and / or receiving. That is, transmission can be sending, receiving, or a combination of sending and receiving; no specific limitation is made here.

[0194] Furthermore, "receiving" can also be understood as detection, listening, etc., without being limited here. For example, "receiving DCI" usually refers to "listening to DCI".

[0195] 9. In this application, "for indicating" can include both direct and indirect indication. When describing an indication information as indicating A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0196] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementation, there are many ways to instruct the information to be instructed. For example, it can be implemented through direct instruction, such as through the information to be instructed itself or its index. It can also be implemented indirectly by instructing other information, where there is a relationship between the other information and the information to be instructed. Alternatively, only a part of the information to be instructed can be indicated, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent.

[0197] The information to be indicated can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device. This configuration information can include, for example, but not limited to, one or a combination of at least two of RRC signaling, medium access control (MAC) layer signaling, and physical layer signaling. MAC layer signaling includes, for example, MAC CE; physical layer signaling includes, for example, downlink control information (DCI).

[0198] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and in the various implementation methods / methods / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various implementation methods / methods / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various implementation methods / methods / implementations within each embodiment can be combined according to their inherent logical relationships to form new embodiments, implementation methods, methods, or implementation approaches. The following embodiments of this application do not constitute a limitation on the scope of protection of this application.

[0199] To facilitate understanding of the methods provided in the embodiments of this application, the system architecture of the methods provided in the embodiments of this application will be described below. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the solutions of the embodiments of this application and does not constitute a limitation on the solutions provided in the embodiments of this application.

[0200] Please see FIG. 1A This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. FIG. 1A As shown, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The RAN 100 includes at least one RAN node (e.g., ...). FIG. 1A 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). FIG. 1A RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. FIG. 1A (Not shown in the image). Terminal device 120 is wirelessly connected to RAN node 110, and RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0201] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, an NR system, or a future radio access system as defined in 3GPP. RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0202] RAN nodes, also known as radio access network equipment, RAN entities, or access nodes, are used to help terminal devices access communication systems wirelessly. In one application scenario, an RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, or a base station in a future mobile communication system. RAN nodes can also be macro base stations (such as...) FIG. 1A 110a in the text), can also be a micro base station or an indoor station (such as... FIG. 1A 110b in the middle can also be a relay node or a donor node.

[0203] In another application scenario, multiple RAN nodes can collaborate to help terminal devices achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RANC) and Medium Access Control (MAC) layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as within a baseband unit (BBU). RUs can be included in radio frequency equipment, such as remote radio units (RRUs) or active antenna units (AAUs). CUs can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0204] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, a RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes.

[0205] In addition, RAN nodes can also be called network devices, which are devices deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices can include various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, etc. The name of the network device may differ in systems employing different radio access technologies, such as eNB or eNodeB (Evolutionary NodeB) in Long Term Evolution (LTE). Network devices can also be radio controllers in Cloud Radio Access Network (CRAN) scenarios. Network devices can also be base station equipment in future 5G networks or network devices in future evolved PLMN networks. Network devices can also be wearable devices or vehicle-mounted devices. Network devices can also be Transmission and Reception Points (TRPs). Furthermore, in a network architecture, network devices can include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN devices including both CU and DU nodes. For ease of description, a base station will be used as an example of a RAN node in the following description.

[0206] A terminal device is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from a base station. Terminal devices can also be referred to as user equipment (UE), mobile stations, mobile terminal devices, etc. They can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technologies or device forms used in the terminal devices.

[0207] Base stations and terminal equipment can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminal equipment.

[0208] The roles of base stations and terminal devices can be relative, for example, FIG. 1A The helicopter or drone 120i can be configured as a mobile base station. For terminal devices 120j that access the wireless access network 100 via 120i, terminal device 120i is a base station; however, for base station 110a, 120i is a terminal device, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminal devices can be collectively referred to as communication equipment. FIG. 1A The 110a and 110b in the text can be referred to as communication devices with base station functions. FIG. 1A The 120a-120j in the text can be referred to as communication equipment with terminal device functions.

[0209] Communication between base stations and terminal devices, between base stations, and between terminal devices can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0210] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal device can be executed by modules (such as chips or modems) within the terminal device, or by a device that includes terminal device functions.

[0211] As can be understood, RAN100, as previously described, includes at least one RAN node (e.g., FIG. 1A 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). FIG. 1A 120a-120j in the series are collectively referred to as 120).

[0212] In one possible implementation method FIG. 1A The communication system shown can also be as follows FIG. 1B As shown, it includes one RAN node 110 and multiple terminal devices (such as...). FIG. 1B (Referring to 120A and 120B in the original text). In this case, a single RAN node can transmit data or control signaling to one or more terminal devices.

[0213] In another possible way of implementation FIG. 1A The communication system shown can also be as follows FIG. 1C As shown, this includes multiple RAN nodes (such as...) FIG. 1C 110 (110A, 110B, and 110C) 110 and a terminal device 120. In this case, multiple RAN nodes can also transmit data or control signaling to a single terminal device simultaneously.

[0214] Optionally, FIG. 2 The diagram illustrates RAN100 as an example of an O-RAN system, which may include components other than those shown in the diagram. FIG. 2 As shown, network devices are also called access network devices. Access network devices (RAN, such as eNB, gNB, or next-generation access network devices) communicate with the core network (CN) via backhaul links and with user equipment (UE) via air interfaces.

[0215] Specifically, the baseband unit (BBU) in the access network equipment communicates with the core network via a backhaul link, and the radio unit (RU) in the access network equipment communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located.

[0216] A BBU includes at least one central unit (CU) and at least one distributed unit (DU), which can communicate via at least one midhaul link.

[0217] Furthermore, FIG. 3 An example diagram of the network element function division and protocol layer structure of an O-RAN device is shown.

[0218] In some examples, the CU is a logical node that carries the Radio Resource Control (RRC) layer, Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, and other control functions of the access network equipment. The CU connects to network nodes such as the core network through interfaces, which can be interfaces such as E2 interfaces. Optionally, the CU may have some core network functions. The CU (e.g., the PDCP layer and higher layers) connects to the DU (e.g., the RLC layer and lower layers) through interfaces, which can be interfaces such as the F1 interface. In some examples, these interfaces (e.g., the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the F1 signaling procedures in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0219] In some examples, the CU can be split into CU-CP (Control Unit-Control Plane) and CU-UP (Control Unit-User Plane). CU-CP is a logical node carrying the RRC layer and PDCP-C (Control plane part of PDCP) layer, used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be Access and Mobility Function (AMF) elements, such as the Access and Mobility Management Function (AMF) in a 5G system. AMF elements are responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the SDAP layer and PDCP-U (User plane part of PDCP) layer, used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network, such as the UPF (User Plane Function) in a 5G system, are responsible for data forwarding and receiving in terminal devices. The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements, such as by latency. Functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0220] In some examples, a DU is a logical node that carries the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, Higher Physical Layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which may be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0221] In some examples, the RU is a logical node carrying both Lower Physical Layer (Lower PHY) and Radio Frequency (RF) processing. In some examples, the RU can be a 3GPP Transmission Reception Point (TRP), a Remote Radio Head (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0222] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include LLS-C and LLS-U interfaces providing the control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via an LLS-M interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0223] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0224] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples.

[0225] With the application of massive MIMO technology, directional beams can be formed by adjusting the weights of the antenna array, improving beam gain and reducing interference to the surrounding environment. Especially in 5G systems, as frequency bands increase, high-frequency transmission path loss increases, necessitating beamforming technology to create beams pointing in different directions, thereby improving coverage performance. In the millimeter-wave band (frequency range 2, FR2), terminal devices can use antenna arrays to form beams to overcome high-frequency coverage issues.

[0226] For example FIG. 4A In the beam management scheme shown, network devices (e.g., base stations) transmit different reference signals in different directions. These network devices transmit synchronization signals and physical broadcast channel blocks (SSBs). Terminal devices measure the results of each SSB, such as the reference signal received power (RSRP). This allows them to determine the optimal transmit beam (Tx beam) for the terminal device. Simultaneously, in FR2, the terminal device also has a receive beam (Rx beam). By using different Rx beams to receive the SSBs transmitted by the network, the terminal device can determine the optimal Rx beam for SSB1.

[0227] In the beam management process, network devices obtain the quality of different beams by configuring the measurement and reporting of reference signals. However, the measurement and reporting behavior of terminal devices is controlled by the network devices. If the network devices want to know the beam information of terminal devices more frequently, they can configure periodic reference signals / reporting for the terminal devices, but this comes at the cost of consuming a large amount of uplink resources. If the network devices want to save uplink resources, they can configure non-periodic reporting, triggering the terminal devices to report only when needed, but the network devices may not be able to detect changes in beam quality in a timely manner.

[0228] A process for triggering beam reporting by the terminal device has been discussed. Specifically, the terminal device measures the reference signal, and when certain defined events are met, the terminal device triggers a report. The current standard introduces the following conditions for the event to be met: the quality of the current "new beam" is better than that of the current beam and exceeds a threshold.

[0229] However, when there are multiple measurement results for the new beam or the current beam, it can lead to an excessive number of times the event is satisfied, resulting in frequent reporting by the terminal device. Furthermore, excessively frequent measurements of a single reference signal may not provide additional gain but could instead cause power consumption issues for the terminal device.

[0230] For example, FIG. 4B As shown, the reference signal for the new beam is called RSn, and the reference signal for the current beam is called RSc. The propagation period of RSn is shorter than the propagation period of RSc. That is, within a certain time period, the number of RSn signals is greater than the number of RSc signals. FIG. 4B As shown, in the process of determining an event instance, a measurement result of one RSc may generate multiple instances (e.g., FIG. 4B (4 instances in the text). This can lead to an excessive number of times the event is satisfied, resulting in frequent reporting by the terminal device. Furthermore, the measurement result of this RSc may be an instantaneous result due to channel fading, etc. Using this instantaneous result for multiple instance judgments of the event can also affect the false triggering of the event.

[0231] To address the aforementioned technical problems, this application provides several approaches. The following description uses a comparison between two types of reference signals (reference signal 1 and reference signal 2) as an example to illustrate these approaches. It is understood that reference signal 1 can refer to the aforementioned RSn, and reference signal 2 can refer to the aforementioned RSc. Alternatively, reference signal 1 can refer to the aforementioned RSc, and reference signal 2 can refer to the aforementioned RSn; the specific meaning is not limited here.

[0232] The first approach is used to determine whether a single instance of an event satisfies the requirement that the measurements of the two types of reference signals be the most recently obtained measurements. Under this approach, the most recently obtained measurement can refer to the latest measurement of either of the two types of reference signals, or it can mean that the measurements of both types of reference signals must be the most recently obtained measurements.

[0233] The second approach is that the measured values ​​of the two types of reference signals used in the previous instance of an event that has already been judged cannot be used to judge previous event instances, or cannot be used to judge subsequent event instances, or cannot be used to judge either previous or subsequent event instances.

[0234] The third approach is to use a single measurement value to determine one event instance. Alternatively, this can be understood as the evaluation of an event instance corresponding to the same measurement value being recorded as one instance of the event.

[0235] The fourth approach is to evaluate whether an instance of an event satisfies the condition by taking the larger of the two transmission periods corresponding to the two types of reference signals.

[0236] The fifth approach is to use the larger of the two types of reference signal transmission periods as the measurement period. This approach can also be understood as measurement relaxation. That is, measurement is performed without a reference signal, using the larger transmission period mentioned above for periodic measurements.

[0237] It should be noted that the above approaches all address how to determine whether an instance used to judge an event satisfies the measured value (or measurement result). Alternatively, these approaches can be understood as addressing how to determine the reference signal used to judge whether an instance of an event satisfies the criteria. Or, the approach provided in this application proposes a method for the terminal device to select the measurement results of the new beam and the current beam to determine the number of events that an instance satisfies, thus avoiding false triggering of events.

[0238] The above ideas are described below with reference to the accompanying diagrams. Please refer to the attached diagrams. FIG. 5 This application provides a flowchart illustrating a communication method, which includes steps 501 to 503. Steps 501 to 503 can be executed by a communication device. "Communication device" can refer to the communication device itself (e.g., a terminal device and / or network device), a component within the communication device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the communication device. The communication device can be one of the aforementioned... FIG. 1A to FIG. 4BThe terminal device or network device in the communication system shown. The following description uses the example of execution by a communication device. The processing performed by a single execution entity in steps 501 to 503 can also be divided into execution by multiple execution entities, which can be logically and / or physically separated. For example, if the communication device is a network device, the processing performed by the communication device can be divided into execution by at least one of CU, DU, and RU.

[0239] Step 501: The network device sends a plurality of first reference signals and at least one second reference signal to the terminal device.

[0240] The network device sends multiple first reference signals and at least one second reference signal to the terminal device. Correspondingly, the terminal device receives the multiple first reference signals and at least one second reference signal sent by the network device.

[0241] In this context, "multiple first reference signals" can refer to two or more first reference signals transmitted by the network device within a first time window. "At least one second reference signal" can refer to one or more first reference signals transmitted by the network device within a first time window. Alternatively, "multiple first reference signals" can also refer to two or more first reference signals received by the terminal device within a second time window. "At least one second reference signal" can also refer to one or more first reference signals received by the terminal device within a second time window.

[0242] It should be noted that if the time delay between transmission and reception is considered, the first time window and the second time window may differ. If the time delay is not considered, the first time window can be approximated by the second time window. For ease of description, the "reception time window" and "transmission time window" will be uniformly described as the transmission time window, that is, the network device and the terminal device transmit multiple first reference signals and at least one second reference signal within the transmission time window.

[0243] Optionally, the first reference signal can be understood as a reference signal transmitted according to a first transmission cycle. The second reference signal can be understood as a reference signal transmitted according to a second transmission cycle.

[0244] Furthermore, the first transmission period of the plurality of first reference signals differs from the second transmission period of at least one second reference signal. For example, the first transmission period may be greater than or less than the second transmission period. Alternatively, this can be understood as the number of first reference signals transmitted within the transmission time window differing from the number of second reference signals transmitted. Additionally, the first transmission period and the second transmission period may or may not be divisible, but this is not specifically limited here.

[0245] For example, the transmission time window includes a reference signal with a longer period and multiple reference signals with shorter periods.

[0246] For example, such as FIG. 6 As shown, the first transmission period T1 of the first reference signal is less than the second transmission period T2 of the second reference signal. From... FIG. 6 It can be seen that in transmission time window 1, the number of first reference signals transmitted between the network device and the terminal device is 3, and the number of second reference signals transmitted between the network device and the terminal device is 1.

[0247] In one possible implementation, multiple first reference signals are reference signals configured for network devices, and at least one second reference signal includes at least one of the following: a reference signal associated with the active transmission configuration indicator (TCI) of the physical downlink channel, a quasi-co-located (QCL) source reference signal of the active TCI of the physical downlink channel, an SSB that has a QCL relationship with the active TCI of the physical downlink channel, a reference signal associated with the beam / TCI currently used by the terminal device, etc. The physical downlink channel may include at least one of the following: a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), etc.

[0248] In this approach, multiple first reference signals can be understood as corresponding to the aforementioned "new beam." At least one second reference signal can be understood as corresponding to the aforementioned "current beam." That is, the first reference signal can be referred to as RSn, and the second reference signal can be referred to as RSc.

[0249] In another possible implementation, at least one second reference signal is a reference signal configured by the network device, and the plurality of first reference signals include at least one of the following: a reference signal associated with the active TCI of the physical downlink channel, a QCL source reference signal of the active TCI of the physical downlink channel, an SSB that has a QCL relationship with the active TCI of the physical downlink channel, a reference signal associated with the beam / TCI currently used by the terminal device, etc.

[0250] In this approach, multiple first reference signals can be understood as corresponding to the aforementioned "current beam," and at least one second reference signal can be understood as corresponding to the aforementioned "new beam." That is, the first reference signal can be called RSc, and the second reference signal can be called RSn.

[0251] Unless otherwise specified, the following description uses RSn as the first reference signal and RSc as the second reference signal as an example.

[0252] To facilitate understanding, let's first explain the relevant concepts of an event. An event can be the basis for a terminal device to determine whether to report a beam measurement report. For example, if the event is met, the terminal device reports a beam measurement report to the network device. Conversely, if the event is not met, the terminal device does not need to report a beam measurement report to the network device.

[0253] There are several scenarios for whether an event is satisfied. Example 1: If the measurement value corresponding to the new beam is better than the measurement value of the current beam, the event can be considered satisfied. Example 2: If the measurement value corresponding to the new beam is better than the measurement value of the current beam and exceeds a first threshold, the event can be considered satisfied. Example 3: If the measurement value corresponding to the new beam is better than the measurement value of the current beam than a first threshold, and the number of times it is better than the first threshold exceeds a second threshold, the event can be considered satisfied.

[0254] It is understandable that the examples above regarding whether the events are satisfied are just examples. In practical applications, there may be other examples, which are not limited here.

[0255] Furthermore, an event can include at least one instance. For example, in Example 1 or Example 2 above, the event includes one instance, and the fulfillment of the instance can also be referred to as event fulfillment. As another example, in Example 3 above, the event includes multiple instances, and the number of times the second threshold is met by multiple instances can be referred to as time fulfillment.

[0256] Optionally, the network device can configure the terminal device for beam measurement report reporting, and the terminal device determines the reference signals for the new beam and current beam measurements. There may be multiple reference signals corresponding to the new beam within transmission time window 1, and there may be at least one reference signal corresponding to the current beam within transmission time window 1. An event occurs when the measurement result for the new beam is better than the measurement result for the current beam by more than a threshold.

[0257] Furthermore, network devices can configure event reporting parameters for terminal devices. For example, the number of instances M where an event is satisfied within time T, where T represents a preset time period and M represents an integer greater than or equal to 0. Another example is a threshold value indicating that the measurement result of the new beam is better than the measurement result of the current beam. Here, T can be the same as or different from the time period occupied by the aforementioned transmission time window.

[0258] Step 502: The terminal device determines the third reference signal and the fourth reference signal.

[0259] After receiving multiple first reference signals and at least one second reference signal, the terminal device determines a third reference signal and a fourth reference signal.

[0260] Specifically, the terminal device determines a third reference signal from a plurality of first reference signals, and the terminal device determines a fourth reference signal from at least one second reference signal.

[0261] There are several cases for the third and fourth reference signals in this application, which are described below.

[0262] In the first case, the third reference signal is the latest of the plurality of first reference signals. And / or the fourth reference signal is the latest of at least one second reference signal.

[0263] This can also be understood as the third reference signal being the newest among the multiple first reference signals. Alternatively, it can be understood as the third reference signal being the latest in the time domain among the multiple first reference signals. Or, it can be understood as the third reference signal being the reference signal with the latest measurement time among the multiple first reference signals.

[0264] In one possible implementation, the number of at least one second reference signal is one. That is, the number of second reference signals within the transmission time window is one.

[0265] In this configuration, since there is at least one second reference signal, this second reference signal can be considered equivalent to the fourth reference signal.

[0266] For example, continuing from the above FIG. 6 For example, the third reference signal and the fourth reference signal are as follows: FIG. 7 As shown, the network device and the terminal device transmit one second reference signal and three first reference signals within transmission time window 1. Therefore, the one second reference signal within transmission time window 1 is the fourth reference signal. The third reference signal is the latest first reference signal in the time domain within transmission time window 1.

[0267] For example, the third reference signal and the fourth reference signal are as follows: FIG. 8 As shown, the network device and the terminal device transmit one second reference signal and five first reference signals within transmission time window 2. Therefore, the one second reference signal within transmission time window 1 is the fourth reference signal. The third reference signal is the latest first reference signal in the time domain within transmission time window 1.

[0268] In another possible implementation, the number of at least one second reference signal can be multiple. That is, the number of second reference signals within the transmission time window is two.

[0269] In this approach, the fourth reference signal can be the latest among the multiple second reference signals. Similar to the description of the third reference signal above, the fourth reference signal is the newest among the multiple second reference signals. Alternatively, it can be understood as the latest time-domain reference signal among the multiple second reference signals. Or, it can be understood as the reference signal with the latest measurement time among the multiple second reference signals.

[0270] It is understandable that this method can be combined with other factors to determine the third and / or fourth reference signals, but specific details are not limited here.

[0271] In the second scenario, the third reference signal is one of the multiple first reference signals that was not used to determine an event instance. And / or the fourth reference signal is at least one of the second reference signals that was not used to determine an event instance.

[0272] This can also be understood as the third reference signal being the reference signal corresponding to the measured value among multiple first reference signals that was not used to determine whether an instance of the event satisfies the condition. Alternatively, it can be understood as the third and / or fourth reference signals being used only to determine whether a single instance of the event satisfies the condition.

[0273] It is understandable that if only one of the multiple first reference signals is not used to determine an event instance, then that first reference signal can be determined as the third reference signal. If there are many first reference signals that are not used to determine an event instance, the third reference signal can also be determined in conjunction with other factors; however, this is not specifically limited here.

[0274] Optionally, the fourth reference signal is a reference signal among at least one second reference signal that was not used in determining the event instance. Accordingly, if there is only one second reference signal among at least one second reference signal that was not used in determining the event instance, then that second reference signal can be determined as the fourth reference signal. If there are multiple second reference signals among at least one second reference signal that were not used in determining the event instance, the fourth reference signal can also be determined in conjunction with other factors; specific details are not limited here.

[0275] Among them, the other situations mentioned above may include at least one of the following situations: the first situation mentioned above, the fourth situation that follows, etc., which are not specifically limited here.

[0276] Furthermore, if the measured values ​​corresponding to the third reference signal and the fourth reference signal are used to determine whether one instance of the event is satisfied, then the measured values ​​corresponding to the third reference signal and the fourth reference signal cannot be used to determine whether other instances of the event are satisfied after that determination.

[0277] For example, the third reference signal and the fourth reference signal are as follows: FIG. 9 As shown, the network device and the terminal device transmit two second reference signals and five first reference signals within the transmission time window 3. The first second reference signal and the second first reference signal are used to determine instances of the event. Therefore, the second reference signal among the two second reference signals that did not participate in the determination of instances of the event is identified as the fourth reference signal. It can be seen that... FIG. 9 Of the five first reference signals shown, four have not been involved in the event example judgment. Therefore, the third reference signal can be determined from these four first reference signals by combining other factors. For example, the first reference signal closest in time domain to the fourth reference signal can be selected as the third reference signal. Alternatively, the first reference signal furthest in time domain from the fourth reference signal can be selected as the third reference signal, and so on. Specific details are not limited here.

[0278] It is understandable that the second case can be attributed to the first case mentioned above or combined with the first case mentioned above to determine the third and fourth reference signals. That is, the reference signal that does not participate in judging whether the event satisfies the conditions can also be called the new reference signal.

[0279] In the third case, multiple comparisons of the third reference signal are considered as one instance of the event. And / or multiple comparisons of the fourth reference signal are considered as one instance of the event.

[0280] This situation can be understood as contradicting the second situation mentioned above. Specifically, the second situation describes a reference signal that has been used to determine an instance of an event once, and is no longer used as a reference signal for determining an instance. The third situation, however, describes multiple comparisons of the reference signal as a single instance. It can be seen that both the second and third situations can resolve the issue of multiple triggering of event instances, but their approaches differ.

[0281] For example, such as FIG. 10 As shown, assuming the fourth reference signal is compared four times with each of the four first reference signals, these four comparisons are considered one instance of the event. That is, the four comparisons trigger only one instance judgment. Compared to the aforementioned... FIG. 4B In such cases, this method can reduce the false triggering of event instances.

[0282] In the fourth case, the time-domain interval between the third reference signal and the fourth reference signal is less than or equal to the preset interval.

[0283] This can also be understood as the third reference signal being the first reference signal among multiple first reference signals that is closer in time domain to the fourth reference signal. Alternatively, it can be understood as the fourth reference signal being the second reference signal among at least one second reference signal that is closer in time domain to the third reference signal.

[0284] In one possible implementation, the terminal device first determines the fourth reference signal from at least one second reference signal, and then further determines the first reference signal among a plurality of first reference signals that is closer in time domain to the fourth reference signal as the third reference signal.

[0285] The terminal device can determine the fourth reference signal in other ways, such as the aforementioned methods, and no specific method is specified here.

[0286] In another possible implementation, the terminal device first determines the third reference signal from a plurality of first reference signals, and then further determines the second reference signal that is closer in time domain to the third reference signal from at least one second reference signal as the fourth reference signal.

[0287] Similarly, the terminal device can determine the third reference signal in other ways, such as the aforementioned methods, which are not limited here.

[0288] It should be noted that the above situations can be combined with each other, and the above situations are only examples. In practical applications, there may be other ways, which are not limited here.

[0289] Step 503: The terminal device determines whether the instance used to determine the event satisfies the third and fourth measurement values.

[0290] After determining the third reference signal and the fourth reference signal, the terminal device determines whether the instance used to judge the event satisfies the third measurement value and the fourth measurement value. The third measurement value includes the measurement value corresponding to the third reference signal, and the fourth measurement value includes the measurement value corresponding to the fourth reference signal.

[0291] The measured values ​​in the embodiments of this application can be used to determine the quality of the reference signal, etc. For example, the measured values ​​may include at least one of the following: reference signal receiving power (RSRP), reference signal receiving quality (RSRP), signal to interference plus noise ratio (SINR), modulation and coding scheme (MCS), channel quality indicator (CQI), etc.

[0292] This step involves a lot of content, so it will be broken down into several parts (the measurement period of the measured value, the evaluation period of the event, the third measurement value, and the fourth measurement value) and described separately below.

[0293] Part One: Measurement Period of Measured Values.

[0294] The measurement period of the measured value can also be called the measurement period of the reference signal. That is, the measurement period is used to indicate how often the reference signal is measured.

[0295] The inventors considered that the first transmission period of multiple first reference signals differs from the second transmission period of at least one second reference signal, which may result in a larger number of one type of reference signal and a smaller number of the other type within a certain transmission time window. This could lead to the terminal device not knowing how to compare the two types of reference signals when subsequently determining event instances, or it could easily result in multiple comparisons, causing frequent reporting or false event triggering by the terminal device.

[0296] Based on this, this application proposes a "relaxed measurement" solution. That is, the larger of the transmission periods of the two types of reference signals is taken as the measurement period for the measured value. In other words, the reference signal with the shorter transmission period does not need to be measured frequently, achieving "relaxed measurement" and thus saving energy consumption of the terminal equipment.

[0297] For example, the second transmission period of at least one second reference signal is greater than the first transmission period of multiple first reference signals, and the second transmission period serves as the measurement period of the multiple first reference signals.

[0298] For example, the first transmission period of multiple first reference signals is greater than the second transmission period of at least one second reference signal, and the first transmission period serves as the measurement period of at least one second reference signal.

[0299] For example, if the transmission period of RSn is 20 milliseconds (ms) and the transmission period of RSc is 80 ms, then RSn can be measured according to the larger transmission period, i.e., the 80 ms period.

[0300] Alternatively, the relaxation measurements described above may also have certain specific conditions.

[0301] For example, relaxed measurement conditions include at least one of the following: the reference signal being relaxed is only associated with a specific event (e.g., Event-2), the reference signal being relaxed is not associated with normal periodic / aperiodic reporting, the terminal device needs to normally measure the reference signal, the type of the reference signal is new beam, etc.

[0302] Furthermore, in the case of relaxed measurement, the terminal device can further limit the reference signal being relaxed:

[0303] For example, when relaxing the measurement of a reference signal, the terminal device needs to select the closest signal to the one used for comparison for measurement. For instance, if the terminal device relaxes the measurement of RSn and compares RSn with RSc to determine the event, then the terminal device needs to select the reference signal closest to RSc (either the previous or the next one). The terminal device does not need to measure RSn at other locations, and the network device can schedule data normally at these unmeasured reference signal locations without scheduling restrictions. For example, if RSn is relaxed, for a comparison object where RSn occurs four times, the location closest to RSc is selected.

[0304] For example, the reference signal for relaxation measurement can be predefined or configured by network devices, etc., and is not limited here.

[0305] Furthermore, when there are multiple RSn or multiple RSc, how to determine the measurement period of each RS? Several possibilities are given below.

[0306] In one possible implementation, the network device also sends multiple fifth reference signals to the terminal device. Correspondingly, the terminal device receives the multiple fifth reference signals sent by the network device. The period of the multiple fifth reference signals is a third transmission period, and the third measurement value includes the measurement value corresponding to the third reference signal and the measurement values ​​of the multiple fifth reference signals. For ease of subsequent description, this example uses multiple fifth reference signals and multiple first reference signals as one type of reference signal, and at least one second reference signal as another type of reference signal. For example, the fifth reference signal and the first reference signal are two RSn signals with different transmission periods, the first reference signal is denoted as RSn1, the fifth reference signal as RSn2, and the second reference signal as RSc.

[0307] In this method, there are several possible measurement periods for the measured value or reference signal, which will be described below.

[0308] To facilitate understanding, the specific process of determining the measurement period will be described in the following examples.

[0309] Example 1: The first transmission period of RSn1 is 40ms, the third transmission period of RSn2 is 80ms, and the second transmission period of RSc is 20ms.

[0310] Example 2: The first transmission period of RSn1 is 20ms, the third transmission period of RSn2 is 80ms, and the second transmission period of RSc is 40ms.

[0311] Example 3: The first transmission period of RSn1 is 20ms, the third transmission period of RSn2 is 40ms, and the second transmission period of RSc is 80ms.

[0312] 1. The measurement period of RSn1 is the larger of the first transmission period and the second transmission period of RSc. The measurement period of RSn2 is the larger of the third transmission period and the second transmission period of RSc.

[0313] This situation can also be understood as comparing the transmission periods of two Rsn with RSc respectively, and taking the larger transmission period as the measurement period of the corresponding RSn.

[0314] For example, continuing with Example 1 above, the measurement period of RSn1 is the larger of the first transmission period and the second transmission period of RSc. The measurement period of RSn1 can be expressed as Max(40ms, 20ms), that is, the measurement period of RSn1 is 40ms. Then, the measurement period of RSn2 is the larger of the third transmission period and the second transmission period of RSc. The measurement period of RSn1 can be expressed as Max(80ms, 20ms), that is, the measurement period of RSn2 is 80ms.

[0315] For example, continuing with Example 2 above, the measurement period of RSn1 is the larger of the first transmission period and the second transmission period of RSc. The measurement period of RSn1 can be expressed as Max(20ms, 40ms), that is, the measurement period of RSn1 is 40ms. Then, the measurement period of RSn2 is the larger of the third transmission period and the second transmission period of RSc. The measurement period of RSn1 can be expressed as Max(80ms, 40ms), that is, the measurement period of RSn2 is 80ms.

[0316] For example, continuing with Example 3 above, the measurement period of RSn1 is the larger of the first transmission period and the second transmission period of RSc. The measurement period of RSn1 can be expressed as Max(20ms, 80ms), meaning the measurement period of RSn1 is 80ms. Then, the measurement period of RSn2 is the larger of the third transmission period and the second transmission period of RSc. The measurement period of RSn1 can be expressed as Max(40ms, 80ms), meaning the measurement period of RSn2 is 80ms.

[0317] 2. The measurement period of RSc is the larger of the fourth and second transmission periods.

[0318] The fourth transmission cycle includes any one of the following: the largest transmission cycle between the first and third transmission cycles, the smallest transmission cycle between the first and third transmission cycles, or the average cycle between the first and third transmission cycles. The following example illustrates this with the fourth transmission cycle being the smallest of the first and third transmission cycles.

[0319] For example, continuing with Example 1 above, the fourth transmission period is the smallest of the first and third transmission periods, which can be expressed as Min(40ms, 80ms), i.e., the fourth transmission period is 40ms. Furthermore, the measurement period of RSc is the larger of the fourth and second transmission periods, which can be expressed as Max(40ms, 20ms), i.e., the measurement period of RSc is 40ms.

[0320] For example, continuing with Example 2 above, the fourth transmission period is the smallest of the first and third transmission periods, which can be expressed as Min(20ms, 80ms), i.e., the fourth transmission period is 20ms. Furthermore, the measurement period of RSc is the larger of the fourth and second transmission periods, which can be expressed as Max(20ms, 40ms), i.e., the measurement period of RSc is 40ms.

[0321] For example, continuing with Example 3 above, the fourth transmission period is the smallest of the first and third transmission periods, which can be expressed as Min(20ms, 40ms), meaning the fourth transmission period is 20ms. Furthermore, the measurement period of RSc is the larger of the fourth and second transmission periods, which can be expressed as Max(20ms, 80ms), meaning the measurement period of RSc is 80ms.

[0322] 3. The measurement period of RSc is the smaller of the fifth and sixth transmission periods.

[0323] Among them, the fifth transmission cycle is the longest transmission cycle between the first and second transmission cycles, and the sixth transmission cycle is the longest transmission cycle between the first and third transmission cycles.

[0324] Optionally, the smaller of the fifth and sixth transmission cycles is used as the measurement cycle of the second reference signal RSc.

[0325] Furthermore, the measurement period of RSn1 is the larger of the first transmission period and the measurement period of RSc. Correspondingly, the measurement period of RSn2 is the larger of the third transmission period and the measurement period of RSc.

[0326] For example, continuing with Example 1 above, the fifth transmission period is the longest of the first and second transmission periods, and can be represented as Max(40ms, 20ms), meaning the fifth transmission period is 40ms. The sixth transmission period is the longest of the first and third transmission periods, and can be represented as Max(40ms, 80ms), meaning the sixth transmission period is 80ms. Therefore, the measurement period of RSc is the shorter of the fifth and sixth transmission periods, and can be represented as Min(40ms, 80ms), meaning the measurement period of RSc is 40ms.

[0327] Furthermore, continuing with Example 1 above, the measurement period of RSn1 is the larger of the first transmission period and the measurement period of RSc. The measurement period of RSn1 can be expressed as Max(40ms, 40ms), meaning the measurement period of RSn1 is 40ms. Correspondingly, the measurement period of RSn2 is the larger of the third transmission period and the measurement period of RSc. The measurement period of RSn2 can be expressed as Max(80ms, 40ms), meaning the measurement period of RSn2 is 80ms.

[0328] For example, continuing with Example 2 above, the fifth transmission period is the longest of the first and second transmission periods, and can be represented as Max(20ms, 40ms), meaning the fifth transmission period is 40ms. The sixth transmission period is the longest of the first and third transmission periods, and can be represented as Max(20ms, 80ms), meaning the sixth transmission period is 80ms. Therefore, the measurement period of RSc is the shorter of the fifth and sixth transmission periods, and can be represented as Min(40ms, 80ms), meaning the measurement period of RSc is 40ms.

[0329] Furthermore, continuing with Example 2 above, the measurement period of RSn1 is the larger of the first transmission period and the measurement period of RSc. The measurement period of RSn1 can be expressed as Max(20ms, 40ms), that is, the measurement period of RSn1 is 40ms. Correspondingly, the measurement period of RSn2 is the larger of the third transmission period and the measurement period of RSc. The measurement period of RSn2 can be expressed as Max(80ms, 40ms), that is, the measurement period of RSn2 is 80ms.

[0330] For example, continuing with Example 3 above, the fifth transmission period is the longest of the first and second transmission periods, and can be represented as Max(20ms, 80ms), meaning the fifth transmission period is 80ms. The sixth transmission period is the longest of the first and third transmission periods, and can be represented as Max(20ms, 40ms), meaning the sixth transmission period is 40ms. Furthermore, the measurement period of RSc is the shorter of the fifth and sixth transmission periods, and can be represented as Min(80ms, 40ms), meaning the measurement period of RSc is 80ms.

[0331] Furthermore, continuing with Example 3 above, the measurement period of RSn1 is the larger of the first transmission period and the measurement period of RSc. The measurement period of RSn1 can be expressed as Max(20ms, 80ms), that is, the measurement period of RSn1 is 80ms. Correspondingly, the measurement period of RSn2 is the larger of the third transmission period and the measurement period of RSc. The measurement period of RSn2 can be expressed as Max(40ms, 80ms), that is, the measurement period of RSn2 is 80ms.

[0332] It is understandable that the aforementioned methods are just examples, and there may be other methods in practical applications, which are not limited here.

[0333] In another possible implementation, the network device also sends multiple sixth reference signals to the terminal device. Correspondingly, the terminal device receives the multiple sixth reference signals sent by the network device. The period of the multiple sixth reference signals is a seventh transmission cycle, the fourth measurement value includes the measurement value corresponding to the fourth reference signal and the measurement values ​​corresponding to the multiple sixth reference signals, and the evaluation period of the event or the measurement period of the measurement value is the larger of the eighth transmission cycle and the first transmission cycle.

[0334] The eighth transmission cycle includes any one of the following: the largest transmission cycle between the second and seventh transmission cycles, the smallest transmission cycle between the second and seventh transmission cycles, or the average cycle between the second and seventh transmission cycles.

[0335] It should be noted that, given the numerous transmission cycles described in the specification (i.e., the fifth and sixth transmission cycles have already been used), the concepts of a seventh and eighth transmission cycle are introduced here for distinction. Since the claims do not explicitly use the concepts of a seventh and eighth transmission cycle, the seventh transmission cycle here is equivalent to the fifth transmission cycle in the claims, and the eighth transmission cycle here is equivalent to the sixth transmission cycle in the claims.

[0336] Optionally, the determination of the measurement period and / or whether to trigger a relaxation measurement can be determined based on an instruction from the network device. For example, the network device sends first information to the terminal device, the first information indicating that the larger of the first transmission period of the first reference signal and the transmission period of at least one second reference signal is the measurement period of the measured value.

[0337] Part Two: The Event Assessment Cycle

[0338] The evaluation cycle of an event can be understood as how often an event is evaluated to determine whether it meets the requirements.

[0339] Alternatively, the evaluation period for an event can also adopt the same method as the measurement period in the first part above, which will not be elaborated here.

[0340] For example, the evaluation period of an event is the larger of the first transmission period of multiple first reference signals and the second transmission period of at least one second reference signal.

[0341] For example, when there are multiple RSn or multiple RSc, how to determine the measurement period of each RS? The process of determining the evaluation period can be similar to the determination of the measurement period in the first part mentioned above, and will not be repeated here.

[0342] Optionally, the evaluation period described above can be determined based on an instruction from the network device. For example, the network device sends an instruction to the terminal device, the instruction indicating that the larger of the first transmission period of the first reference signal and the transmission period of at least one second reference signal is used as the evaluation period of the event.

[0343] Part Three: The Third and Fourth Measurements.

[0344] There are several possible scenarios for the third and fourth measurements in this step, which will be described below.

[0345] In the first scenario, the third measurement value is the measurement value of the aforementioned third reference signal. And / or the fourth measurement value is the measurement value of the aforementioned fourth reference signal.

[0346] In this case, the third measurement value can be described with reference to the various cases of the aforementioned third reference signal. The fourth measurement value can be described with reference to the various cases of the aforementioned fourth reference signal.

[0347] For example, the third reference signal is the latest of the multiple first reference signals. This can be understood as the third measurement value corresponding to the latest of the multiple first reference signals. As another example, the fourth reference signal is the latest of the at least one second reference signal. This can be understood as the fourth measurement value corresponding to the latest of the at least one second reference signal.

[0348] For example, multiple comparisons of the third reference signal can be considered as one instance of an event. This can be understood as multiple comparisons of the third measurement value being considered as one instance of an event. Similarly, multiple comparisons of the fourth reference signal can be considered as one instance of an event. This can be understood as multiple comparisons of the fourth measurement value being considered as one instance of an event.

[0349] For example, the third reference signal is used only to determine whether a single instance of the event is satisfied. This can be understood as the third measurement value being used only to determine whether a single instance of the event is satisfied. Similarly, the fourth reference signal is used only to determine whether a single instance of the event is satisfied. This can be understood as the fourth measurement value being used only to determine whether a single instance of the event is satisfied.

[0350] For example, the time-domain interval between the third reference signal and the fourth reference signal is less than a preset interval. This can be understood as the time-domain symbol interval between the third reference signal corresponding to the third measurement value and the fourth reference signal corresponding to the fourth measurement value being less than a preset interval.

[0351] In the second scenario, the third measurement value includes, in addition to the aforementioned third reference signal measurement value, the measurement values ​​of other reference signals. And / or the fourth measurement value includes, in addition to the aforementioned fourth reference signal measurement value, the measurement values ​​of other reference signals.

[0352] Optionally, the terminal device also receives multiple fifth reference signals sent by the network device, and the third measurement value includes the measurement value corresponding to the third reference signal and the measurement values ​​of the multiple fifth reference signals.

[0353] Optionally, the terminal device also receives multiple sixth reference signals sent by the network device, and the fourth measurement value includes the measurement value corresponding to the fourth reference signal and the measurement values ​​of the multiple sixth reference signals.

[0354] In the third scenario, the third measurement value is the filtered value of multiple first reference signals. And / or the fourth measurement value is the filtered value of at least one second reference signal.

[0355] This situation can also be understood as how to determine the third measurement value when the terminal device does not perform relaxed measurement.

[0356] Optionally, for reference signals with shorter periods, the terminal device still performs measurements according to the normal period. However, when determining whether an event instance is satisfied, the reference signal with shorter periods is filtered, and the filtered signal is compared with the reference signal with longer periods to determine whether the event instance is satisfied.

[0357] For example, if the first transmission period of the first reference signal is less than the transmission period of the second reference signal, then multiple first reference signals within the transmission time window can be filtered and compared with the fourth measurement value to determine whether an instance of the event is satisfied.

[0358] For example, if the first transmission period of the first reference signal is greater than the transmission period of the second reference signal, then multiple second reference signals within the transmission time window can be filtered and compared with the third measurement value to determine whether an instance of the event is satisfied.

[0359] The filtering in this application embodiment can be understood as the process of turning multiple measurements into one measurement, which can be averaging, weighted averaging, etc., and is not limited here.

[0360] The number of reference signals to be filtered can be determined by the first transmission period and the second transmission period. For example, the number of filters can be the ratio of the larger transmission period of the two types of reference signals to the smaller transmission period of the two types of reference signals.

[0361] For example, such as FIG. 11 As shown, the terminal device performs normal measurements on the short-period RSn. Before acquiring the RSc result, it has already obtained multiple RSn measurement values. For example, the transmission period of RSn is 80ms, and the transmission period of RSc is 20ms. Therefore, for RSc, four (i.e., 4 = 80 / 20) reference signal measurement values ​​are needed for filtering. The multiple RSc measurement values ​​are filtered, and the filtered value is used compared with the fourth RSn measurement value to determine the event instance. That is, as... FIG. 11 The elliptical portion represents the four RSn measurement values ​​acquired by the terminal device. After filtering the four RSn values, a third measurement value is obtained. This third measurement value is then compared with the fourth measurement value to determine if an instance of the event satisfies the procedure.

[0362] It is understandable that the aforementioned measurement values ​​are just examples. In practical applications, there are other methods, which will not be specified here.

[0363] Optionally, whether the terminal device uses filtering to determine event instances, and / or the specific filtering method, can be determined according to the instructions of the network device. For example, the network device sends second information to the terminal device, the second information indicating whether the filtered value of the measured values ​​corresponding to multiple first reference signals is compared with the transmitted fourth measured value of the second reference signal to determine whether a single instance of the event is satisfied.

[0364] Step 504: The terminal device sends a measurement report to the network device. This step is optional.

[0365] Optionally, after determining the third and fourth measurement values, the terminal device can perform a judgment process based on the third and fourth measurement values ​​to determine whether an instance of an event is satisfied. If the number of times an instance is satisfied in an event exceeds a threshold, the terminal device can send a measurement report to the network device. Accordingly, the network device receives the measurement report sent by the terminal device.

[0366] Optionally, the event is the number of instances M in time T where the event is satisfied, where T represents a preset time period and M represents an integer greater than or equal to 0. For example, the event could be a threshold value indicating that the measurement result of the new beam is better than that of the current beam. Here, T can be the same as or different from the time period occupied by the aforementioned transmission time window.

[0367] Furthermore, measurement reports are used by network devices to switch beams. For example, after receiving a measurement report from a terminal device, if the network device finds a new RSn that is more suitable for the terminal device, it will update the transmission beam.

[0368] For example, taking the event as the number of times the event is satisfied within time T, M, if the terminal device determines that the number of times the event instances are satisfied exceeds a threshold within a certain period, the terminal device sends a measurement report to the network device. The corresponding network device receives the measurement report sent by the terminal device.

[0369] In this embodiment of the application, the content included in the measurement report is not specifically limited. For example, it may include the relevant measurement value of the better reference signal in the event. For example, if the number of times RSn is better than RSc in time T exceeds a threshold, the measurement report may carry parameters such as the measurement value of RSn. The specifics are not limited here.

[0370] It should be noted that the different situations in the aforementioned parts can be combined arbitrarily, and no specific restrictions are imposed here.

[0371] Based on the above scheme, on the one hand, the measured values ​​of the two types of reference signals used to determine whether a single instance of an event satisfies the requirements must be the most recently obtained measured values. Under this approach, the most recently obtained measured value can refer to the latest measured value of either of the two types of reference signals, or it can mean that the measured values ​​of both types of reference signals must be the most recently obtained measured values. On the other hand, the measured values ​​of the two types of reference signals used to determine whether a previous instance of an event satisfies the requirements cannot be used to determine previous event instances, or subsequent event instances, or both. Furthermore, a single measured value is used to determine a single event instance. Alternatively, it can be understood that the evaluation of event instances corresponding to the same measured value is recorded as a single instance of the event. Furthermore, the evaluation period for determining whether a single instance of an event satisfies the requirements is the larger of the two transmission periods corresponding to the two types of reference signals. Additionally, the larger transmission period of the two types of reference signals is used as the measurement period for the measured value. This approach can also be understood as measurement relaxation. That is, measurement is performed without the presence of a reference signal, and periodic measurements are performed based on the larger transmission period mentioned above. The above-mentioned aspects propose regulations on how terminal devices should select the measurement results of the new beam and the current beam to determine the number of event instances that are satisfied, thus avoiding false event triggering. Specifically, by defining how the terminal device selects the measurement value or reference signal when determining whether an event instance is satisfied, it avoids false event reporting due to multiple judgments of event satisfaction caused by the instantaneous channel state, thereby preventing network devices from incorrectly judging the beam status of the terminal device. Furthermore, by defining the relaxation of the reference signal measurement by the terminal device, power saving is achieved.
