Description

Technical Field

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

[0002] In the field of wireless communication technology, to address the problem of untimely channel quality measurement, early channel state information (CSI) measurement methods have emerged to trigger CSI measurements earlier. For example, when a terminal device initiates random access to enter a connected state from a non-connected state (idle and inactive state), early CSI measurements are performed based on the channel state information reference signal (CSI-RS) for a short period after entering the connected state. However, due to differences between different terminal devices—for example, some terminal devices do not support early CSI measurement while others do—and variations in the number and density of CSI-RS ports, the required set of configuration parameters differs for different terminal devices. Therefore, how to reasonably configure the appropriate set of CSI-RS parameters for different terminal devices has become an urgent technical problem to be solved. Summary of the Invention

[0003] This application provides a wireless communication method, wireless communication device, and communication system that can reasonably configure a set of relevant parameters for appropriate channel state information for different terminal devices, thereby improving communication quality.

[0004] In a first aspect, a wireless communication method is provided. This method can be executed by a network device, or by a component (such as a circuit, chip, or chip system) configured in the network device, or by a logic module or software capable of implementing all or part of the functions of the network device. This application does not limit this approach. The following description uses a network device (such as a satellite) as an example.

[0005] The method includes: transmitting a System Information Block (SIB), wherein SIB1 includes first indication information and SIBX includes second indication information, the first indication information being used to indicate at least one detection capability of Channel State Information Reference Signal (CSI-RS) that the terminal device can support, and the second indication information being used to indicate a set of measurement parameters for CSI-RS measurement corresponding to each detection capability.

[0006] In this technical solution, network devices use a hierarchical synchronous indication mechanism (SIB1+SIBX) to specify the capabilities and configuration parameter sets of CSI-RS signals. SIB1 indicates the detection capability, and SIBX indicates the parameter sets corresponding to different detection capabilities. This allows terminal devices to match their own detection capability from the first indication information in SIB1 based on their own capability-related parameters. Then, based on their own capabilities, they can parse the parameter set corresponding to their own detection capability from SIBX as needed. This achieves the goal of rationally configuring appropriate CSI-RS related parameter sets for different terminal devices, thereby effectively improving the measurement quality of CSI. This solution allows different terminal devices to parse only the parameter set corresponding to their own capabilities, instead of needing to parse all CSI-related parameters in all SIBs and then analyze the parameters they can use, saving the amount of data that needs to be parsed and analyzed, and improving processing efficiency. Furthermore, by providing different capabilities and their corresponding relationships, different terminal devices can first determine their own capabilities based on their own capability-related parameters and then obtain the corresponding configuration parameters. This allows for the simultaneous configuration of relevant parameters for terminal devices with different capabilities, improving the flexibility and rationality of the parameter configuration process.

[0007] Furthermore, this solution does not require changes to the existing communication architecture; it only explicitly restricts the CSI measurement content in the SIB, thus achieving the goal of flexibly and reasonably configuring CSI measurement parameters for different terminal devices. Therefore, it is highly compatible with existing communication solutions and easier to implement. For example, it can be directly applied to current and future 3GPP protocol frameworks, reusing existing mechanisms. Without altering existing communication standards, it achieves the effect of flexibly and reasonably configuring differentiated parameters for terminal devices, reducing the complexity of standardization and deployment, and facilitating widespread adoption.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the first indication information includes first data and second data, the first data includes capability parameters corresponding to each of at least one detection capability, and the second data includes the correspondence between the detection capability and the set of measurement parameters.

[0009] In this implementation, the first instruction information simultaneously provides the relevant parameters of the capability and the correspondence between the parameter set and the capability. This allows the terminal device to quickly match its own capability from the first data based on its own capability parameters, and then quickly lock the parameter set based on the second data. Thus, it only needs to wait for its own parameter set to arrive before reading and parsing. Without adding too much burden to SIB1, it can effectively improve data processing efficiency.

[0010] In one example, the capability parameters include at least one of the following: whether early CSI is supported, the number of ports supported, the set of supported reporting content, and the measurement cycle.

[0011] In this example, a variety of optional capability parameters are provided to improve the flexibility of configuring related parameters.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, each detection capability corresponds to at least one set of measurement parameters, each measurement mode corresponds to one set of measurement parameters, and the measurement modes supported by the terminal device include at least one measurement mode.

[0013] This implementation refines the correspondence between detection capabilities and measurement parameter sets, as well as the correspondence between measurement modes and measurement parameter sets, making it easier to adapt to the parameter configuration of CSI-RS measurements in existing communication frameworks.

[0014] In one example, at least one measurement mode includes at least one of the following: periodic measurement (PCSI) mode, one or more semi-continuous measurement (SPCSI) modes.

[0015] In this example, the main purpose is to make the measurement mode include at least one continuous measurement mode. Continuous measurement can obtain multiple measurement values ​​within a time period, thereby more accurately determining the CSI quality, i.e., improving measurement accuracy.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, a SIBX contains all the sets of measurement parameters, or each SIBX contains at most one set of measurement parameters, or a SIBX contains all the sets of measurement parameters corresponding to a detection capability.

[0017] This implementation offers multiple ways to store measurement parameter sets, allowing for flexible selection based on actual application needs. One SIBX contains all measurement parameter sets, meaning all sets are placed in a single SIBX. This allows for convenient, one-time reading of all sets without distinction. However, it places demands on the UE's read speed, and during parsing, it's necessary to select the set the UE needs to parse from all sets, resulting in a large number of sets to filter. Therefore, this approach is suitable for scenarios with a small total number of sets. Another approach, where each SIBX contains at most one measurement parameter set, allows the UE to selectively read one or more SIBXs based on the set it needs to parse. During parsing, only the sets of read SIBXs need to be parsed. This method essentially performs the filtering during the read process, enabling indiscriminate parsing. Therefore, this approach is suitable for scenarios where the total number of measurement parameter sets does not exceed the total number of SIBXs, and is particularly suitable for scenarios where multiple SIBXs can be read simultaneously. By placing the set of measurement parameters for the same detection capability within the same SIBX, a one-to-one correspondence is established between the SIBX and the detection capability. This allows for the simultaneous reading of all parameter sets corresponding to the UE's own detection capability, from which the set of parameters to be parsed can be selected. This represents a compromise between the two methods mentioned above, balancing the number of parameters read and the selection base. Therefore, this method is suitable for scenarios with a large total number of sets. It achieves rapid selection and parsing by coarsely screening all parameter sets corresponding to the capability and then finely screening to pinpoint the specific set of measurement parameters to be parsed. Each of the above-mentioned bearer methods has its advantages, thus further enhancing the flexibility of the proposed solution and facilitating on-demand configuration based on actual communication scenarios.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: receiving a first message from a first terminal device, the first message including third indication information, the third indication information being used to indicate that the first terminal device has a first detection capability, the first detection capability being one of at least one detection capability; sending a second message to the first terminal device, the second message being used to instruct the first terminal device to perform CSI-RS measurement according to a target parameter set, the target parameter set being one of at least one set of measurement parameters corresponding to the first detection capability.

[0019] In this implementation, the configuration scheme of this application is integrated into the communication framework of early CSI measurements. The reporting of UE detection capabilities and the triggering of CSI-RS measurements are accomplished through a first message and a second message. Both the first and second messages are one-to-one interactive messages between the first terminal device and the network device. This implementation effectively improves measurement quality while minimizing modifications to the existing communication framework.

[0020] In one example, the second message includes at least one of the following indications: target measurement mode and target parameter set, wherein the measurement parameter set corresponding to the target measurement mode is the target parameter set; the target measurement mode is a measurement mode corresponding to the first detection capability among at least one measurement mode that the terminal device can support.

[0021] In another example, the target parameter set is one of the sets of at least one set of measurement parameters that is in an unused state.

[0022] In this example, conflicts with other user interfaces are avoided by limiting the selection to sets that are not in use.

[0023] In one example, the higher the detection capability, the more measurement parameters are associated with that detection capability. The target parameter set is the set of measurement parameters that the first detection capability has and that other detection capabilities below the first detection capability do not have.

[0024] In this example, the selection rules are further refined. Following the logic of backward compatibility, the set of measurement parameters that can only be used by higher capabilities is prioritized. This ensures the best possible measurement results while minimizing resource contention with lower capabilities.

[0025] In one example, the higher the detection capability, the more measurement parameters are corresponding to that detection capability; the target parameter set is the set of at least one measurement parameter set that is in an unused state, and when there are multiple sets in an unused state, the target parameter set is the set of measurement parameters that the second detection capability has and that other detection capabilities below the second detection capability do not have, and the second detection capability is a detection capability that is no higher than the first detection capability.

[0026] In this example, by using a hierarchical selection method, the rationality of the selected target parameter set can be further improved, thereby further improving the measurement quality.

[0027] In another example, the second message also includes measurement window information, which indicates the time period during which the first terminal device performs CSI-RS measurements.

[0028] In this example, by configuring the measurement window information, the specific measurement behavior of different terminal devices can be further flexibly controlled.

[0029] Optionally, the measurement window information includes at least one of the following: measurement start time, measurement duration, measurement end time, and measurement result reporting timing.

[0030] In this example, the content of the measurement window information is further refined, and more detailed measurement parameters are provided to improve the flexibility and certainty of control over the specific measurement process.

[0031] Secondly, a wireless communication method is provided. This method can be executed by a terminal device, or by a component (such as a circuit, chip, or chip system) configured in the terminal device, or by a logic module or software capable of implementing all or part of the functions of the terminal device.

[0033] The second aspect is the implementation on the terminal device side, which corresponds to the first aspect. The explanations, supplements, and descriptions of the beneficial effects of the first aspect also apply to the second aspect, and will not be repeated here.

[0034] In conjunction with the second aspect, in some implementations of the second aspect, the first indication information includes first data and second data. The first data includes capability parameters corresponding to each of at least one detection capability, and the second data includes the correspondence between the detection capability and the set of measurement parameters. Obtaining at least one set of measurement parameters corresponding to the first terminal device based on the first indication information and the second indication information includes: determining the first detection capability corresponding to the first terminal device based on the capability parameters of the first terminal device and the first data; determining at least one set of parameters corresponding to the first detection capability based on the first detection capability and the second data; and reading at least one set of parameters from the second indication information.

[0035] In one example, the method further includes: sending a first message to a network device, the first message including indication information of a first detection capability; and, upon receiving a second message, performing CSI-RS measurements according to a target parameter set indicated by the second message, the target parameter set being one of at least one set of measurement parameters corresponding to the first detection capability.

[0036] Optionally, the second message also includes measurement window information, which is used to indicate the time period for the first terminal device to perform CSI-RS measurement; upon receiving the second message, performing CSI-RS measurement according to the target parameter set indicated by the second message includes: performing CSI-RS measurement according to the target parameter set within the time period indicated by the measurement window information.

[0073] To facilitate understanding of the embodiments of this application, the terminology used in this application will be briefly explained first. Optionally, the explanation of some terms may also refer to the explanations in the 3rd Generation Partnership Project (3GPP) standard protocol.

[0074] 1. Radio Resource Control (RRC) layer

[0075] RRC (Radio Control Registry) is a Layer 3 protocol in the control plane of mobile communication systems (such as UMTS, LTE, and 5G), responsible for signaling interaction between terminal devices and network devices. Its core responsibility is to configure, manage, and schedule air interface resources to ensure efficient spectrum utilization while meeting quality of service requirements. In other words, RRC achieves fine-grained control over radio resources through system information broadcasting, connection management, resource allocation, mobility control, and security mechanisms, making it the core control layer ensuring the efficient and reliable operation of mobile communication networks.

[0076] RRC states (5G / 4G) include Idle (RRC_IDLE), Inactive (RRC_INACTIVE), and Connected (RRC_CONNECTED). It should be understood that there is no case sensitivity for the English representations of these three states, as long as they clearly represent the three states. In the Idle RRC state, the terminal device has not established an RRC connection and only receives system information and paging. In the Inactive RRC state, some context is retained to reduce power consumption and facilitate rapid connection recovery. In the Connected RRC state, a complete signaling bearer has been established, allowing for service configuration, measurement, handover, etc.

[0077] When switching from an idle or inactive state (RRC-Idle / Inactive state) to a connected state (RRC-Connected state), downlink transmission can only use a low-throughput transmission scheme for a short period after entering the connected state due to the lack of prior measurement reporting information. To address this problem, and similarly, the low throughput issue when a secondary cell is first activated, antenna switching SRS and aperiodic channel state information (CSE) reference signals were developed. Solutions for early triggering mechanisms for reference signals (CSI-RS), aperiodic channel state information reports (CSI reports), etc.

[0078] Besides the need for an early triggering mechanism to initiate measurements when the terminal device switches from an idle or inactive state (RRC-Idle / Inactive) to a connected state (RRC-Connected), the early stages of state transitions, such as when a secondary cell (SCell) is just activating or waking up from sleep, may also present a lack of prior measurement reporting information. Therefore, the solution proposed in this application can also be used in these situations. In short, the solution proposed in this application can be used in any initial access scenario in wireless communication where CSI quality needs to be measured.

[0079] 2. Reference signal (RS) and sounding reference signal (SRS)

[0080] Reference signals are known, predefined transmitted signals that serve as "landmarks" for network devices (such as gNBs and eNodeBs) and terminal equipment (UEs) to perform channel estimation, synchronization, and measurement. Probe reference signals, on the other hand, are a special type of uplink reference signal, primarily used to measure uplink channel quality and utilize channel reciprocity to assist downlink transmission. In other words, reference signals can include both downlink and uplink reference signals, but probe reference signals are always uplink signals.

[0081] This application primarily concerns CSI-RS and CSI-SRS, the former being a downlink signal and the latter an uplink signal. Network devices transmit CSI-RS to measure channel quality and perform beam management, and this transmission can be performed on the Physical Downlink Shared Channel (PDSCH) resource. Terminal devices (UEs) transmit CSI-SRS to network devices to obtain uplink channel information, and this transmission can be performed on either the Physical Uplink Shared Channel (PUSCH) or the Physical Uplink Control Channel (PUCCH) resource. To a certain extent, CSI-RS can be understood as a tool for network devices to perceive the communication environment, while CSI-SRS is a tool for terminal devices to inform network devices of their location.

[0082] 3. Periodic, semi-persistent, and aperiodic.

[0083] Periodic, semi-persistent, and aperiodic scheduling are all scheduling strategies that can be used when measuring channel quality information, differing in the determinism versus flexibility of resource allocation. Periodicity strictly follows a preset time interval (e.g., once every N time slots). Semi-persistent scheduling is based on a preset period, but network devices can pause or resume transmission at any time via DCI (downlink control information). Aperiodic scheduling is completely on-demand and randomly triggered, and can be triggered in real-time by DCI. Combining these scheduling strategies with CSI, RS, and SRS can be used to represent scheduling-strategy-based CSI, RS, and SRS, for example, A. SRS (aperiodic sounding reference signal, A-SRS) can also be abbreviated as ASRS, which is an aperiodic, on-demand triggered SRS. Other combinations will not be listed one by one.

[0084] This application mainly relates to measurement modes such as periodic measurement mode and semi-persistent measurement mode of CSI-RS. The SIB1 can indicate the measurement parameter sets corresponding to multiple modes of each detection capability, so that the UE can further select the target measurement parameter set from at least one measurement parameter set that matches its own capability selected from the SIBX based on the measurement mode adopted.

[0085] 4. System Information Block (SIB)

[0086] SIB is the core mechanism in 5G NR (New Radio) networks used to broadcast cell configuration parameters. It is periodically sent by network devices (such as gNBs) to the terminal equipment (UE), enabling the UE to understand how to access the network, perform handover, and conduct measurements. In the 5G standard, SIB is strictly divided into two levels: Minimum System Information (MSI) and Other System Information (OSI). MSI includes the most basic information necessary for initial access, while OSI includes more detailed cell configuration and neighbor cell information. MSI includes the Main Information Block (MIB) and the Remaining Minimum System Information (SIB1). OSI includes SIBX. In one communication standard, SIBX includes SIB2-SIB9, meaning X takes values ​​from 2 to 9. However, in other communication standards, SIBX can also include SIB10 and above, meaning X can be an integer greater than or equal to 10.

[0087] SIB1 contains the scheduling information list for all other SIBs, which tells the terminal device when and under what conditions it can acquire other SIBs. SIBX, on the other hand, provides specific service parameters (such as power control, reselection threshold, and neighbor cell list). SIB1 is transmitted via periodic broadcast, while SIBX can be transmitted either periodically or on demand to connected UEs.

[0088] CSI is typically measured by the UE and reported to the network device, while SIB is the configuration issued by the network device to the UE. In one implementation, CSI-related configuration parameters are included in SIB2-SIB5. However, it should be understood that this application does not limit which OSI-based SIBs are included.

[0089] It should be understood that since there are no precise Chinese names for SIB1 and SIBX, SIB1 (system information block type 1) can be referred to as system information entry, SI master / scheduler, cell access control block, etc., and SIBX can be referred to as other system information (OSI), cell specific configuration, service related parameters, etc., without any limitation.

[0090] In scenarios where the UE establishes a connection from the IDLE / INACTIVE state, traditional solutions only support one-time aperiodic Early CSI-RS triggering. Inaccurate measurement results from this early CSI-RS can lead to poor subsequent communication quality. Therefore, this solution can only provide relatively coarse-grained channel quality measurements, making it difficult to meet the requirements of fine-grained scheduling and stable link establishment. Although communication standards do not prohibit network devices from sending periodic or semi-persistent CSI-RS in the early stages, before RRC configuration is complete, terminal and network devices cannot flexibly choose whether to use periodic, semi-persistent, or other scheduling strategies. Therefore, traditional solutions struggle to perform continuous and controllable CSI measurement and reporting during the initial access period. Furthermore, while traditional solutions propose that CSI configuration information can be carried by the SIB and mention the pre-configuration of various capabilities and corresponding parameter sets, the method for distributing this extensive configuration information remains unclear. This makes it impossible to adapt to the differentiated configurations of different terminal devices. The periodic broadcast method of the SIB further exacerbates the difficulty of flexibly configuring different terminal devices.

[0091] To address the aforementioned issues, this application provides a hierarchical indication scheme of SIB1+SIBX. SIB1 indicates the capability information of the detection capability, while SIBX indicates the set of configuration parameters corresponding to different detection capabilities. This allows different terminal devices to determine their own capabilities based on the capability information and then select the corresponding set of measurement parameters for parsing as needed. This scheme does not require changes to the existing communication architecture; it only explicitly restricts the CSI measurement content in the SIB. With minimal modifications, it achieves the goal of flexibly and reasonably configuring CSI measurement parameters for different terminal devices, thus facilitating wider adoption.

[0092] The solution provided in this application will be described in detail below with reference to the corresponding flowcharts. It is understood that the illustrative flowcharts provided in this application primarily use different devices (e.g., terminal devices, network devices) as examples of the execution subjects of this interactive illustration to illustrate the method, but this application does not limit the execution subjects of the interactive illustrations. For example, the devices (e.g., terminal devices, network devices) in the illustrative flowcharts can also be chips, chip systems, or processors that support the implementation of this method on the device, or logic modules or software that can implement all or part of the functions of the device.

[0093] As a general statement, the message or signaling interactions involved in the interaction process of this application embodiment can be standard messages or signaling or newly introduced messages or signaling. This application embodiment does not make specific limitations on this.

[0094] Figure 2 This is a schematic flowchart illustrating a wireless communication method according to an embodiment of this application. It can be understood that... Figure 2 The terminal device in the middle can be Figure 1 Any terminal device in the context of network equipment can refer to any component within that terminal device (such as a processor, chip, or chip system). Network equipment can be... Figure 1 Any access network device, or a component within an access network device (such as a processor, chip, or chip system). The following section... Figure 2 The steps shown will be explained.

[0095] S201. The network device sends a system information block (SIB) to at least one terminal device (UE), and the at least one terminal device receives the SIB.

[0096] The at least one terminal device includes a first terminal device (first UE).

[0097] SIB1 in SIB includes first indication information, and SIBX includes second indication information. The first indication information is used to indicate the detection capability of multiple Channel State Information Reference Signals (CSI-RS) that the terminal device can support, and the second indication information is used to indicate the set of measurement parameters for CSI-RS measurement corresponding to each detection capability.

[0098] In one implementation, the first indication information includes first data and second data. The first data includes capability parameters corresponding to each of the at least one detection capability, and the second data includes the correspondence between the detection capability and the set of measurement parameters.

[0099] In this implementation, the first instruction information simultaneously provides the relevant parameters of the capability and the correspondence between the parameter set and the capability. This allows the terminal device to quickly match its own capability from the first data based on its own capability parameters, and then quickly lock the parameter set based on the second data. Thus, it only needs to wait for its own parameter set to arrive before reading and parsing. Without adding too much burden to SIB1, it can effectively improve data processing efficiency.

[0100] It should be understood that SIB1 itself needs to include the scheduling information of SIBX. The changes made to SIB1 in this application are only to the CSI-related fields, and there are no changes to other data.

[0101] In one example, the capability parameters include at least one of the following: whether early CSI is supported (EarlyCSI-SupportFlag), the number of ports supported (RxPort-Range), the set of report content supported (Report-Content), and the measurement period (EarlyCSI-Period).

[0102] In this example, a variety of optional capability parameters are provided to improve the flexibility of configuring related parameters.

[0103] In another example, at least one detection capability can be represented by a capability level identifier (EarlyCSI-LevelID).

[0104] For example, SIB1 primarily carries lightweight capability parameters and SIBX scheduling information. Specifically, the function indication field `earlyCSI-supported` identifies whether the cell supports the Early CSI function. Capability parameters can be used for template matching, that is, to determine the identifier of the parameter set. Capability parameters may include: `RxPort-Range`, indicating the default number of CSI-RS ports (e.g., 1 / 2 / 4), which helps the UE determine whether it supports the corresponding number of ports; `Report-Content`, which provides the minimum supported report content set (e.g., a subset of CRI / RI / PMI / CQI); and `EarlyCSI-Period`, indicating the default CSI reporting period. Probe capabilities can be represented using `EarlyCSI-LevelID`, which means that probe capabilities can be represented by capability levels. This allows the UE to compare its actual capability parameters with the capability parameters corresponding to each probe capability, thereby quickly determining whether it belongs to a certain capability level and reporting that capability level when sending the first message. Subsequently, the UE reads the identifier of the corresponding CSI parameter set according to the mapping relationship of "capability level -> SIBX".

[0105] For example, SIBX scheduling information (i.e. SIBX indication information) may include SIBX_indicator and SIBX_schedule, where SIBX_indicator indicates whether a corresponding SIBX exists, and SIBX_schedule indicates the SIBX delivery period (e.g., 80 ms) and SI-window (e.g., 5 ms) for UE configuration detection window.

[0106] It should be understood that the values ​​in the above examples are not limited. In practice, other values ​​can be used as needed. There is also no limit to the number of energy level divisions. As long as at least one detection capability is set, and each detection capability corresponds to a set of capability parameters, the UE can obtain its own detection capability based on its own capability parameters.

[0107] In one implementation, each detection capability corresponds to at least one set of measurement parameters, each measurement mode corresponds to one set of measurement parameters, and the measurement modes supported by the terminal device include at least one measurement mode.

[0108] This implementation refines the correspondence between detection capabilities and measurement parameter sets, as well as the correspondence between measurement modes and measurement parameter sets, thus facilitating better adaptation to the parameter configuration of CSI-RS measurements within existing communication frameworks. By configuring one or more parameter sets for each detection capability, this approach allows different UEs to flexibly select different measurement modes, and the same UE can also select a specific measurement mode or switch between different measurement modes as needed. This further improves the flexibility and rationality of the configuration.

[0109] It should be understood that the measurement mode of this application may not enable early CSI. For ease of understanding, not performing early CSI measurements can also be considered as a measurement mode—no measurement. Similarly, the set of measurement parameters corresponding to no measurement can also be regarded as a special set of parameters—the empty set.

[0110] In addition to non-measurement modes, the measurement modes include at least one of the following: periodic measurement (PCSI) mode, one or more semi-continuous measurement (SPCSI) modes, one or more random measurement modes, and one or more other non-periodic measurement modes.

[0111] In another example, at least one measurement mode includes at least one of the following: periodic measurement (PCSI) mode, one or more semi-continuous measurement (SPCSI) modes.

[0112] In this example, the main purpose is to make the measurement mode include at least one continuous measurement mode. Continuous measurement can obtain multiple measurement values ​​within a time period, thereby more accurately determining the CSI quality, i.e., improving measurement accuracy.

[0113] In one implementation, a SIBX contains all the measurement parameter sets, or each SIBX contains at most one measurement parameter set, or a SIBX contains all the measurement parameter sets corresponding to a detection capability.

[0114] This implementation offers multiple ways to store measurement parameter sets, allowing for flexible selection based on actual application needs. One SIBX contains all measurement parameter sets, meaning all sets are placed in a single SIBX. This allows for convenient, one-time reading of all sets without distinction. However, it places demands on the UE's read speed, and during parsing, it's necessary to select the set the UE needs to parse from all sets, resulting in a large number of sets to filter. Therefore, this approach is suitable for scenarios with a small total number of sets. Another approach, where each SIBX contains at most one measurement parameter set, allows the UE to selectively read one or more SIBXs based on the set it needs to parse. During parsing, only the sets of read SIBXs need to be parsed. This method essentially performs the filtering during the read process, enabling indiscriminate parsing. Therefore, this approach is suitable for scenarios where the total number of measurement parameter sets does not exceed the total number of SIBXs, and is particularly suitable for scenarios where multiple SIBXs can be read simultaneously. By placing the set of measurement parameters for the same detection capability within the same SIBX, a one-to-one correspondence is established between the SIBX and the detection capability. This allows for the simultaneous reading of all parameter sets corresponding to the UE's own detection capability, from which the set of parameters to be parsed can be selected. This represents a compromise between the two methods mentioned above, balancing the number of parameters read and the selection base. Therefore, this method is suitable for scenarios with a large total number of sets. It achieves rapid selection and parsing by coarsely screening all parameter sets corresponding to the capability and then finely screening to pinpoint the specific set of measurement parameters to be parsed. Each of the above-mentioned bearer methods has its advantages, thus further enhancing the flexibility of the proposed solution and facilitating on-demand configuration based on actual communication scenarios.

[0115] In addition to the above-mentioned methods of carrying measurement parameter sets, it is also possible to put all the measurement parameter sets of a measurement mode in the same SIBX. The effect achieved by this method is similar to that of putting the measurement parameter sets with the same detection capability in the same SIBX, except that the coarse screening particle size changes from detection capability to measurement mode.

[0116] Furthermore, based on the backward compatibility of detection capabilities, the parameter set of the lowest detection capability can be placed in one SIBX, while other detection capabilities can only have their parameter sets different from the lowest detection capability placed in the same SIBX. This allows reading only the SIBX containing the lowest detection capability set and the SIBX containing its own unique detection capability set. Additionally, all sets can be deployed completely randomly to any SIBX; other cases will not be listed here.

[0117] To facilitate understanding, specific examples are provided below using Tables 1 and 2. Table 1 is the UE capability level classification table, which is a mapping table showing the correspondence between each detection capability and different capability parameters in at least one detection capability. Table 2 is the mapping table between UE capability levels and early CSI parameter sets, which is an example of the correspondence between each detection capability and different parameter sets. Furthermore, each detection capability can correspond to multiple parameter sets, thus achieving more refined parameter configuration for different communication modes. In other words, Table 1 is an example of the first set of data, and Table 2 is an example of the second set of data. It should be understood that in practice, the first and second sets of data can also exist in other forms. For example, capability parameters may only use the first column, so only two capability levels are needed; or there may be only one SPCSI mode or more, etc., which will not be listed here. In Table 1, the parameters in each row, excluding the energy level, constitute a capability parameter set, which is the set of capability parameters corresponding to the capability level in that row. In Table 2, each row represents one or more parameter sets corresponding to each capability level, and each column other than the capability level represents a measurement parameter set.

[0118] Table 1

[0119]

[0120] As shown in Table 1, the numerical identifier for Capability Level 1 is 00. The value of the capability parameter "Support Early CSI?" is 0, indicating that Early CSI is not supported. The value of the capability parameter "Supported Port Count" is empty. The values ​​of the capability parameters "Supported Report Content Set", "Measurement Period", and "Capability Level" are also empty because it is not necessary to configure the relevant capability parameters for Early CSI. The numerical identifier for Capability Level 2 is 01. The value of the capability parameter "Supported Early CSI?" is 1. The value of the capability parameter "Supported Port Count" is 1. The value of the capability parameter "Supported Report Content Set" is RI+CRI. The value of the capability parameter "Measurement Period" is greater than or equal to 10 milliseconds. The value of the capability parameter "Capability Level" corresponds to Level 2. Capability Level 3 is represented by a value of 10. The capability parameter "Support Early CSI" has a value of 1, the capability parameter "Supported Ports" has a value of 1-2, the capability parameter "Supported Report Content Set" has a value of RI+CRI, the capability parameter "Measurement Period" has a value greater than or equal to 10 milliseconds, and the capability parameter "Capability Level" corresponds to Level 3. Capability Level 4 is represented by a value of 11. The capability parameter "Support Early CSI" has a value of 1, the capability parameter "Supported Ports" has a value of 1-4, the capability parameter "Supported Report Content Set" has a value of RI+CRI+CQI, the capability parameter "Measurement Period" has a value greater than or equal to 5 milliseconds, and the capability parameter "Capability Level" corresponds to Level 4.

[0121] RI stands for Rank Indicator, used to indicate the channel rank (layer number), such as 1, 2, 4, 8 layers. CRI stands for CSI-RS Resource Indicator, used to indicate the optimal CSI-RS resource index, mainly used in beam management. CQI stands for Channel Quality Indicator, used to indicate the channel quality level, providing a key basis for rate matching. It should be understood that with technological advancements, other types of report content may emerge; only adaptive adjustments to the specific content of the first data are needed, and there are no limitations.

[0122] Therefore, after receiving SIB1, the UE reads Table 1 from it and then matches the corresponding capability level based on its actual capability parameters. For example, if a UE supports 2 ports and the supported report content set is RI+CRI, then even without considering the measurement period, its capability level can be determined as level 3, capability level 3, and the numerical identifier is 10. As another example, assuming a UE's measurement period is 6 milliseconds, its capability level can be directly determined as level 4, capability level 4, and the numerical identifier is 11 based on the measurement period. However, it should be understood that Table 1 is only an example; in actual application scenarios, other identification and classification methods for detection capabilities can be used, which will not be listed here.

[0123] Table 2

[0124]

[0125] As shown in Table 2, the numerical identifier for capability level 1 is 00, and the value of the measurement parameter set "PCSI-Config" is 0, indicating that capability level 1 does not support this measurement parameter set; the value of the measurement parameter set "SPCSI-Config [1]" is 0, and the value of the measurement parameter set "SPCSI-Config [2]" is 0, indicating that capability level 1 does not support this measurement parameter set. The numerical identifier for capability level 2 is 01, and the value of the measurement parameter set "PCSI-Config" is 1, indicating that capability level 2 supports this measurement parameter set; the value of the measurement parameter set "SPCSI-Config [1]" is 0, indicating that capability level 2 does not support this measurement parameter set; the value of the measurement parameter set "SPCSI-Config [2]" is 0, indicating that capability level 2 does not support this measurement parameter set. The numerical identifier for capability level 3 is 10, and the value of the measurement parameter set "PCSI-Config" is 1, indicating that capability level 3 supports this measurement parameter set; the value of the measurement parameter set "SPCSI-Config[1]" is 1, indicating that capability level 3 supports this measurement parameter set; the value of the measurement parameter set "SPCSI-Config [2]" is 0, indicating that capability level 3 does not support this measurement parameter set. The numerical identifier for capability level 4 is 11, and the value of the measurement parameter set "PCSI-Config" is 1, indicating that capability level 4 supports this measurement parameter set; the value of the measurement parameter set "SPCSI-Config [1]" is 1, indicating that capability level 4 supports this measurement parameter set; the value of the measurement parameter set "SPCSI-Config [2]" is 1, indicating that capability level 4 supports this measurement parameter set.

[0126] Table 2 provides examples of parameter sets with backward compatibility. That is, if a measurement mode such as SPCSI-Config[2] can be used, the parameter sets of the other two measurement modes can also be used. If a measurement mode such as SPCSI-Config[2] cannot be used, but a measurement mode such as SPCSI-Config[1] can be used, the measurement parameter set of the PCSI-Config measurement mode can also be used. Other cases are not listed.

[0127] Combining Tables 1 and 2, network devices (e.g., gNBs) broadcast a UE capability level classification table (e.g., Table 1) and a mapping table between UE capability levels and Early CSI parameter sets (e.g., Table 2) in SIB1. In the EarlyCSI-SupportFlag, PCSI-Config, SPCSI-Config [1] and SPCSI-Config [2] columns, "1" indicates support and "0" indicates no support. After receiving SIB1, the UE first determines whether it supports Early CSI: if it does not support it, it is classified as capability level 1 and does not participate in Early CSI; if it supports it, it further determines the corresponding capability level (probing capability) based on its own support parameters such as the number of ports it can support, the set of report content, and the measurement period. After determining its own capability level, the UE selects the supported Early CSI parameter set according to the level and reports its own capability level in the subsequent first message (e.g., Msg3) (e.g., using 2 bits to represent, which can distinguish 4 capability levels); on the other hand, it reads the corresponding Early CSI parameter set from the SIBX according to the level. For example, when the UE capability is Level 3, it reports EarlyCSI-LevelID = 10 (binary representation of Level 3) in Msg3, and reads the associated periodic measurement mode (PCSI-Config) and semi-persistent mode (PCSI-Config[1] and PCSI-Config[2]) parameter sets from the SIBX for subsequent Early CSI activation and measurement reporting.

[0128] In one example, the measurement parameters in the measurement parameter set may include at least one of the following: the configuration type of the measurement mode, the number of ports (RxPort-Range), the report content set (Report-Content), the measurement period (EarlyCSI-Period), the CDM type (CDM type), the CSI-RS location (CSI-RS location), and the Uplinkresource ID (Uplinkresource ID).

[0129] In this example, the flexibility of parameter configuration is improved by providing a wider range of measurement parameters.

[0130] Table 3 provides examples of different sets of measurement parameters, that is, examples of at least one set of measurement parameters corresponding to each detection capability. Each row corresponds to one set of measurement parameters. However, it should be understood that the parameters in a set of measurement parameters may be only some of the parameters in Table 3, or may include more parameters; there is no limitation.

[0131] Table 3

[0132]

[0133] As shown in Table 3, the configuration type "PCSI-Config" has 1 port, the report content set is RI+CRI, the measurement period is 10ms, the CDM type is noCDM, the CSI-RS position is freqOffset = 12, sym = 12, and the reported resource identifier is ID = 10 (PUCCH). The configuration type "PCSI-Config[1]" has 2 ports, the report content set is RI+CRI, the measurement period is 10ms, the CDM type is noCDM, the CSI-RS position is freqOffset = 24, sym = 12, and the reported resource identifier is ID = 20 (PUCCH). The configuration type "PCSI-Config[2]" has 4 ports, the report content set is RI+CRI+CQI, the measurement period is 5ms, the CDM type is FD-CDM2, the CSI-RS position is freqOffset = 48, sym = 12, and the reported resource identifier is ID = 21 (PUCCH). Each line represents a set of measurement parameters.

[0134] Referring to Table 3, to support differentiated Early CSI configurations, SIBX can primarily include two types of templates: one is a single P-CSI template (PCSI-Config) for low-overhead, fast measurement, and the other is a set of SP-CSI templates (PCSI-Config[]) for different UE capabilities, with different parameters configured in different templates. Furthermore, a PMI-free CSI report configuration associated with SRS configuration can be provided: SRS templates are represented by the srsTemplateList[] field, and PMI-free report templates are represented by the reportConfigList[] field. A new parameter, reportConfigId_pf, is added to each SRS configuration item (e.g., the i-th srsTemplateList[i]), pointing to a report template in reportConfigList. Thus, early versions of SRS-AS can be used to compare each transmit branch / panel and explicitly bind the corresponding PMI-free report to the actual measured transmit branch, avoiding inconsistencies such as "measurement A, report B" and ensuring that RI / CQI corresponds one-to-one with the actual measured panel.

[0135] It should be understood that the specific parameters and values ​​of different parameters in the above examples can be adjusted according to the actual communication scenario, and there are no limitations.

[0136] It should also be understood that this application mainly involves two types of parameters: capability parameters and measurement parameters. Capability parameters refer to the parameters used to determine the UE's detection capability, while measurement parameters refer to the parameters used by the UE when performing actual CSI measurements.

[0137] Network devices can periodically send SIBs.

[0138] As mentioned above, SIB1 and SIBX can be sent periodically, or SIB1 can be sent periodically while SIBX is only sent to connected UEs. This application does not impose any restrictions on how SIBs are sent in different communication scenarios.

[0139] S202. The first terminal device obtains at least one set of parameters corresponding to the first terminal device according to the first instruction information and the second instruction information.

[0140] The first terminal device is any one of the above-mentioned terminal devices (UEs).

[0141] After receiving the SIB, the first terminal device can extract the CSI measurement-related data from SIB1 and SIBX respectively.

[0142] In one implementation, the first indication information includes first data and second data, the first data including capability parameters corresponding to each of the at least one detection capability, and the second data including the correspondence between each detection capability and the parameter set; obtaining at least one parameter set corresponding to the first terminal device based on the first indication information and the second indication information includes:

[0143] Based on the capability parameters of the first terminal device and the first data, the first detection capability corresponding to the first terminal device is determined;

[0144] Based on the first detection capability and the second data, at least one set of parameters corresponding to the first detection capability is determined;

[0145] Read the at least one set of parameters from the second indication information.

[0146] In this implementation, the first data and the second data are used to determine the detection capability and one or more parameter sets, respectively. Then, the first terminal device can read only the determined set of one or more measurement parameters from the second indication information. This effectively improves processing efficiency and saves on unnecessary data acquisition and analysis of parameter sets.

[0147] In one implementation, the above method further includes steps S203 and S204, which are described below.

[0148] In this implementation, the configuration scheme of this application is integrated into the communication framework of early CSI measurements. The reporting of UE detection capabilities and the triggering of CSI-RS measurements are accomplished through a first message and a second message. Both the first and second messages are one-to-one interactive messages between the first terminal device and the network device. This implementation effectively improves measurement quality while minimizing modifications to the existing communication framework.

[0149] S203. The first terminal device sends a first message to the network device, the first message including indication information of the first terminal device's detection capability. Correspondingly, the network device receives the first message.

[0150] Optionally, the first message includes third indication information, which is used to indicate that the first terminal device has a first detection capability, and the first detection capability is one of at least one detection capability.

[0151] The first message can be Msg3, or it can be any message preceding the second message. By using existing messages in the communication framework, the number of messages transmitted can be reduced, power consumption can be lowered, and transmission efficiency can be improved, without changing the interaction process of the original communication framework. While achieving the new communication effects of this application, it is possible to make as few modifications as possible to the existing transmission scheme.

[0152] It should be understood that step S203 does not necessarily have to be executed after step S202. It can also be executed before or during step S202, as long as it is executed before step S204.

[0153] It should also be understood that since the SIB in step S201 can be periodically broadcast to all UEs corresponding to the network device, and the first message and the second message are one-to-one transmissions between the first terminal device and the network device, there is no necessary sequential relationship between the execution time of step S201 and the execution time of steps S203 and S204. This application does not limit the order of execution of these steps. As long as the data required for this step is available when executing this step, it can be executed. For example, as long as the detection capability of the first terminal device is determined, the first message can be sent. As long as the first detection capability is known from the first message after receiving it, S204 can be executed. Other cases will not be listed one by one.

[0154] S204. The network device sends a second message to the first terminal device, the second message being used to instruct the first terminal device to perform CSI-RS measurement according to the target parameter set.

[0155] The target parameter set is one of the sets of at least one measurement parameter set corresponding to the first detection capability.

[0156] The second message can be Msg4 or any other message. Similarly, using existing messages within the communication framework reduces the number of messages transmitted, lowers power consumption, and improves transmission efficiency, without altering the original communication framework's interaction process. This achieves the new communication effects of this application while minimizing modifications to the existing transmission scheme.

[0157] In one example, the second message includes at least one of the following indications: target measurement mode and target parameter set, wherein the measurement parameter set corresponding to the target measurement mode is the target parameter set; the target measurement mode is a measurement mode corresponding to the first detection capability among at least one measurement mode that the terminal device can support.

[0158] In this example, the target parameter set can be indicated directly, or indirectly by indicating the target measurement mode. Since the first terminal device has already determined a measurement mode matching its own detection capabilities under the guidance of the SIB, the corresponding target measurement set can be determined based on the indication of the target measurement mode. Multiple indication methods can further improve the flexibility of parameter configuration.

[0159] Referring to Table 3, each row represents the set of measurement parameters corresponding to each measurement mode. Therefore, indicating the measurement mode is equivalent to indicating the set of measurement parameters.

[0160] In another example, the target parameter set is one of the sets of at least one set of measurement parameters that is in an unused state.

[0161] In this example, conflicts with other user interfaces are avoided by limiting the selection to sets that are not in use.

[0162] This example shows that just because a UE has detection capabilities does not necessarily mean that it will initiate early CSI.

[0163] A set that is in an unused state can be understood as one in which the parameters (resources) are not occupied by other UEs.

[0164] It should also be understood that network devices can directly select from at least one set of measurement parameters. Alternatively, they can select a set of measurement parameters that is only available for higher-level detection capabilities. This is because detection capabilities have backward compatibility, and higher-level capabilities can select a set of measurement parameters for lower-level capabilities. According to Table 2, capability level 4 can select any of the three parameter sets, while capability level 2 can only select the PCSI parameter set, and capability level 1 cannot perform early CSI, but can only wait to start measurement in the normal trigger mode. Therefore, assuming the detection capability is capability level 4, the SPCSI-config[2] set can be selected, because this set is only available for capability level 4. Other examples will not be listed one by one.

[0165] In one example, the higher the detection capability, the more measurement parameters are associated with that detection capability. The target parameter set is the set of measurement parameters that the first detection capability has and that other detection capabilities below the first detection capability do not have.

[0166] In this example, the selection rules are further refined. Following the logic of backward compatibility, the set of measurement parameters that can only be used by higher capabilities is prioritized. This ensures the best possible measurement results while minimizing resource contention with lower capabilities.

[0167] The two selection strategies mentioned above can also be combined.

[0168] In one example, the higher the detection capability, the more measurement parameters are corresponding to that detection capability; the target parameter set is the set of at least one measurement parameter set that is in an unused state, and when there are multiple sets in an unused state, the target parameter set is the set of measurement parameters that the second detection capability has and that other detection capabilities below the second detection capability do not have, and the second detection capability is a detection capability that is no higher than the first detection capability.

[0169] In this example, by using a hierarchical selection method, the rationality of the selected target parameter set can be further improved, thereby further improving the measurement quality.

[0170] In another example, the second message also includes measurement window information, which indicates the time period during which the first terminal device performs CSI-RS measurements.

[0171] In this example, by configuring the measurement window information, the specific measurement behavior of different terminal devices can be further flexibly controlled.

[0172] In one example, the second message also includes measurement window information, which indicates the time period for the first terminal device to perform CSI-RS measurements; upon receiving the second message, performing CSI-RS measurements according to the target parameter set indicated by the second message includes: performing CSI-RS measurements according to the target parameter set within the time period indicated by the measurement window information.

[0173] In this example, from the perspective of the first terminal device, after receiving the first message, measurement is performed based on the instructions of the measurement window information.

[0174] Optionally, the measurement window information includes at least one of the following: measurement start time, measurement duration, measurement end time, and measurement result reporting timing.

[0175] In this example, the content of the measurement window information is further refined, and more comprehensive measurement parameters are provided to improve the flexibility and certainty of control over the specific measurement process.

[0176] In one example, the measurement window information is the medium access control element (MAC CE).

[0177] Optionally, MAC CE includes three fields: windowStartOffset, indicating the start time of the measurement window; windowDuration, indicating the duration of the measurement; and reportTimingOffset, indicating the timing of CSI measurement result reporting.

[0178] For example, the measurement start time can be represented by an offset from the moment the first terminal device receives the second message. The measurement result reporting timing can be represented by an offset from the measurement end time. The unit of this offset can be a time slot.

[0179] In one implementation, the first indication information includes first data and second data. The first data includes capability parameters corresponding to each of at least one detection capability, and the second data includes the correspondence between detection capabilities and sets of measurement parameters. Obtaining at least one set of measurement parameters corresponding to the first terminal device based on the first and second indication information includes: determining a first detection capability corresponding to the first terminal device based on the capability parameters of the first terminal device and the first data; determining at least one set of parameters corresponding to the first detection capability based on the first detection capability and the second data; and reading at least one set of parameters from the second indication information.

[0180] This implementation describes the steps for the first terminal device to acquire the parameter set. By reading and parsing SIB1 and SIBX in stages, unnecessary data reading and parsing can be reduced, thereby improving processing efficiency.

[0181] Figure 2 The scheme shown employs a hierarchical synchronous indication mechanism (SIB1+SIBX) for network devices to specify the capabilities and configuration parameter sets of CSI-RS signals. SIB1 indicates the detection capability, while SIBX indicates the parameter sets corresponding to different detection capabilities. This allows terminal devices to match their own detection capability from the first indication information in SIB1 based on their own capability-related parameters. Then, based on their own capabilities, they can parse the parameter set corresponding to their specific detection capability from SIBX as needed. This achieves the goal of rationally configuring appropriate CSI-RS parameter sets for different terminal devices, thereby effectively improving the measurement quality of CSI. This scheme allows different terminal devices to parse only the parameter set corresponding to their own capabilities, rather than parsing all CSI-related parameters in all SIBs and then analyzing the parameters they can use. This saves the amount of data that needs to be parsed and analyzed for their own usable parameters, improving processing efficiency. Furthermore, by providing different capabilities and their corresponding relationships, different terminal devices can first determine their own capabilities based on their own capability-related parameters and then obtain the corresponding configuration parameters. This allows for the simultaneous configuration of relevant parameters for terminal devices with different capabilities, improving the flexibility and rationality of the parameter configuration process.

[0182] Furthermore, this solution does not require changes to the existing communication architecture; it only explicitly restricts the CSI measurement content in the SIB, thus achieving the goal of flexibly and reasonably configuring CSI measurement parameters for different terminal devices. Therefore, it is highly compatible with existing communication solutions and easier to implement. For example, it can be directly applied to current and future 3GPP protocol frameworks, reusing existing mechanisms. Without altering existing communication standards, it achieves the effect of flexibly and reasonably configuring differentiated parameters for terminal devices, reducing the complexity of standardization and deployment, and facilitating widespread adoption.

[0183] Figure 3 This is a schematic flowchart illustrating another wireless communication process according to an embodiment of this application. It can be understood that... Figure 3 The terminal device in the middle can be Figure 1 Any terminal device in the context of network equipment can refer to any component within that terminal device (such as a processor, chip, or chip system). Network equipment can be... Figure 1 Any access network device, or a device within an access network device (such as a processor, chip, or chip system). Figure 3 for Figure 2 An example, below Figure 3 The steps shown will be explained.

[0184] It should be noted that in the early CSI procedure, the UE first sends Msg1, the network device (base station) replies with Msg2, then the UE sends Msg3, and after the network device completes contention resolution, it returns Msg4 to the UE. The UE then sends the CSI-SRS signal triggered by Msg4. Msg1 can be a physical random access channel (PRACH), Msg2 can be a random access preamble, Msg3 can be an uplink scheduled transmission or uplink transmission message, and Msg4 can be a contention resolution message.

[0185] It should be understood that SIBs are sent periodically, so there is no necessary sequential relationship between them and subsequent Msg1-Msg4 messages. The information indicated by the SIB may only be used when sending related messages. This application mainly refines how to incorporate CSI measurement parameters into the SIB, thereby improving the flexibility and rationality of parameter configuration and meeting the differentiated needs of different terminal devices.

[0186] S301. The network device periodically broadcasts System Information Block (SIB) messages to at least one terminal device (UE), and the at least one terminal device periodically receives SIB messages.

[0187] The at least one terminal device includes a first terminal device (first UE).

[0188] The first terminal device starts up and first reads SIB1. The network device (e.g., gNB) broadcasts a unified Early CSI capability level classification table (an example of the first data, see Table 1 for details) to all UEs in the cell within SIB1, as well as a mapping relationship between the UE's capability level (an example of detection capability) and the Early CSI parameter set (an example of the measurement parameter set) (an example of the second data, see Table 2 for details). Capability parameters may include the default number of ports, maximum RI, indication of whether Early CSI is supported, and SIBX scheduling information (download cycle and SI-window). Based on these capability parameters, the UE can confirm its own capability level (its own detection capability, an example of the first detection capability) and the Early CSI templates it supports (i.e., at least one set of measurement parameters corresponding to the first detection capability). To ensure that parameter acquisition is completed before Early CSI activation, the UE needs to read the SIBX before Early CSI is sent; at the same time, to avoid conflicts with Early CSI reception, the SI-window (an example of SIBX scheduling information) also needs to be determined before MSG4 is sent.

[0189] S302, the first terminal device sends message Msg1 to the network device. Correspondingly, the network device receives message Msg1.

[0190] S303, The network device sends message Msg2 to the first terminal device. Correspondingly, the first terminal device receives message Msg2.

[0191] S304. The first terminal device sends message Msg3 (an example of the first message) to the network device. Correspondingly, the network device receives message Msg3.

[0192] S305, The first terminal device reads the SIBX.

[0193] The first terminal device can read the corresponding SIBX in the SI-window according to the capability level (first detection capability) corresponding to EarlyCSI-LevelID to obtain the complete Early CSI parameter set configuration (obtain at least one set of measurement parameters corresponding to the first detection capability). For example, if the detection capability of the first terminal device corresponds to PCSI-Config, PCSI-Config[1] and PCSI-Config[2], three sets of measurement parameters can be obtained. For another example, assuming that the Early CSI parameter set is encapsulated in multiple different SIBXX (for example, PCSI-Config in SIBX1, PCSI-Config[1] in SIBX2, and PCSI-Config[2] in SIBX3), then the UE can selectively read the corresponding SIBXX according to EarlyCSI-LevelID.

[0194] like Figure 3 As shown, step S305 can be executed in parallel during steps S302-S304 to improve processing efficiency. Steps S302-S304 can adopt the conventional RACH procedure, which is the existing communication architecture. In this architecture, the UE sends Msg1 to trigger the physical random access channel (PRACH) and waits for the physical random access response (RAR) message. The network device issues a timing advance command (TA) and a temporary uplink grant (UL Grant) in Msg 2 (RAR) to guide the UE to send Msg 3.

[0195] In this application, the UE, in Msg3 (e.g., RRC Connection Request), combines the Early CSI template capability information (first indication information) provided by SIB1, and reports its own capability level related to Early CSI configuration (an example of detection capability) through the 2-bit EarlyCSI-LevelID parameter.

[0196] Based on the EarlyCSI-LevelID reported in Msg3, the network device can determine whether to enable Early CSI measurement for the UE and select which CSI resource set (target measurement set) to perform Early measurements on. If it is determined that Early CSI should be enabled, the network device can include an Early-CSI Activation MAC CE (an example of measurement window information) and an indication of the target measurement set in Msg4 when sending Msg4 to trigger CSI measurements.

[0197] S306. The network device sends Msg4 to the first terminal device. Correspondingly, the first terminal device receives message Msg4.

[0198] The message Msg4 carries Early-CSI Activation MAC CE (an example of measurement window information) and indication information of the target measurement set.

[0199] For example, this MAC CE contains several key fields: pCSI-Activate (1 bit) indicates whether to activate the pre-configured P-CSI template measurement in the SIB; holdAfterReport bit indicates whether the UE continues P-CSI measurement after completing a report; spCSI-ActivateMask (e.g., a 2-bit mask) corresponds to multiple pre-configured semi-persistent CSI templates, setting it to 1 indicates activation of the corresponding SP-CSI template, and setting it to 0 indicates deactivation; srsTemplateList[i] is used to activate the corresponding SRS template, and in conjunction with the reportConfigId_pf read by the UE in the SIBX, explicitly binds the SRS to a certain PMI-free CSI report template in reportConfigList. To improve the CSI triggering timeline, three new fields have been introduced in MAC CE: windowStartOffset indicates the start time of the measurement window, which can be represented by the offset relative to the time slot reference point where the UE confirms successful reception of Msg4; windowDuration indicates the duration of the measurement window; and reportTimingOffset indicates the timing of non-periodic CSI reports, which can be represented by the time slot offset after the measurement window ends.

[0200] S307, The first terminal device parses Msg4.

[0201] The first terminal device receives and parses the Early-CSI ActivationMAC CE in Msg4 (an example of the second message), identifies the activated P-CSI / SP-CSI template (target parameter set) and the corresponding measurement window configuration, and selects a valid template to enter the measurement phase.

[0202] S308. The first terminal device measures the periodic and semi-periodic CSI-SRs issued by the network device during the measurement phase.

[0203] Optionally, the first terminal device can use the time slot of successfully sending a hybrid automatic repeat request acknowledgement (HARQ-ACK) for Msg4 as the absolute time reference point T_ref. This reference point serves as the baseline for subsequent measurement and reporting timing. Based on this, key time parameters for measurement and reporting are determined: the measurement window start time (measurement start time) is T_measurement_start = T_ref + windowStartOffset, and the measurement window end time (measurement end time) is T_measurement_end = T_measurement_start + windowDuration. During the measurement phase, the first terminal device can receive periodic or semi-persistent Early CSI-RS at designated symbol positions and perform multiple sample accumulations and averagings within the measurement window to provide a more stable and reliable CSI estimate in a single aperiodic report. The timing of non-periodic CSI report submission (measurement result submission timing) can be determined by T_report = T_measurement_end + reportTimingOffset. The actual transmission occurs on the first DG PUSCH that meets the conditions after T_report. The submission content is CRI-RI-CQI, and the specific format depends on the configuration parameters.

[0204] S309. After the measurement is completed, the first terminal device sends a non-periodic CSI report (measurement result) to the network device.

[0205] S310, Network devices process non-periodic CSI reports.

[0206] The network device receives and processes the Early CSI reported by the UE, and makes preliminary decisions on beam selection, scheduling parameters, and power control based on the measurement results. For P-CSI mode, if holdAfterReport = 1, the UE can continue to perform subsequent measurements and reports according to the cycle after completing the first report; for SP-CSI mode, the UE strictly follows the activation state and measurement window shown by MAC CE, and stops the corresponding SP-CSI measurement after the measurement window ends or is deactivated.

[0207] By following the steps above, the entire process from SIB1 / SIBX pre-configuration and Msg4 activation to measurement window control and non-periodic CSI reporting can be completed.

[0208] It should be understood that Figure 3 The above three tables are merely specific examples of the proposed solution. In actual application, there are no restrictions on the specific parameters or values ​​involved.

Network equipment can be... Figure 1 Any access network device, or a device within an access network device (such as a processor, chip, or chip system). Figure 4 for Figure 2 An example, below Figure 4 The steps shown will be explained. Figure 3 From the perspective of interaction Figure 2 The solution is illustrated below. Figure 4 This is from the perspective of data processing flow. Figure 2 An example of the solution is provided.

[0210] S401. Network devices broadcast the UE capability level classification table and the early CSI parameter set mapping table through SIB1.

[0211] The UE capability level classification table and the early CSI parameter set mapping table are examples of the first and second data, respectively.

[0212] An example of step S201.

[0213] S402. Determine whether the UE supports early CSI. If the result is yes, proceed to step S403. If the result is no, end the subsequent process.

[0214] S403. The UE (e.g., the first UE) determines its own capability level according to the UE capability level classification table (an example of the first detection capability).

[0215] Steps S402-S403 are an example of step S202. The UE's detection capability is determined through a progressive judgment. However, it should be understood that since the detection capability of this application may not be divided into four levels as shown above, step S403 may not be necessary. For example, if the detection capability only includes support for early CSI and no support for early CSI, then step S403 is unnecessary. Alternatively, step S402 may be skipped, and step S403 can be executed directly.

[0216] S404, Configure the target parameter set.

[0217] S404 may include:

[0218] S404-1, The UE reports its own capability level in Msg3; S404-2, The network device activates the target parameter set according to the UE's capability level; S404-3, The UE reads the corresponding parameter set from SIBX according to its own capability level. S403 can be executed in parallel during steps S404-1 and S404-2 to improve processing efficiency.

[0219] S405, The network device sends a trigger message (second message) for early CSI measurement.

[0224] Figure 5 This is a schematic block diagram of a wireless communication device according to an embodiment of this application. Figure 5 As shown, the communication device 1000 may include a communication module 1001. The communication module 1001 can implement corresponding communication functions, which can be internal communication functions of the communication device 1000 or communication functions between the communication device 1000 and other devices. Optionally, the communication module 1001 may also be referred to as a communication interface or transceiver module.

[0225] Optionally, the communication device 1000 further includes a processing module 1002. The processing module 1002 can perform corresponding processing functions.

[0226] Optionally, the communication device 1000 further includes a storage module, which can be used to store instructions and / or data; the processing module 1002 can read the instructions and / or data in the storage module so that the communication device 1000 can implement the aforementioned method embodiments.

[0227] In one possible design, the communication device 1000 may correspond to the network device in the above method embodiments, or to a component (such as a circuit, chip, or chip system) configured in the network device. The communication device 1000 may be used to perform the steps or processes performed by the network device in any of the above method embodiments.

[0228] For example, the communication module 1001 is used to send a system information block (SIB), wherein SIB1 includes first indication information and SIBX includes second indication information. The first indication information is used to indicate at least one detection capability of the Channel State Information Reference Signal (CSI-RS) that the terminal device can support, and the second indication information is used to indicate the set of measurement parameters for CSI-RS measurement corresponding to each detection capability.

[0229] For example, the first indication information includes first data and second data. The first data includes capability parameters corresponding to each of the at least one detection capability, and the second data includes the correspondence between the detection capability and the set of measurement parameters.

[0230] For example, capability parameters include at least one of the following: whether early CSI is supported, the number of supported ports, the set of supported reporting content, and the measurement cycle.

[0231] For example, each detection capability corresponds to at least one set of measurement parameters, each measurement mode corresponds to one set of measurement parameters, and the measurement modes supported by the terminal device include at least one measurement mode.

[0232] For example, at least one measurement mode includes at least one of the following: periodic measurement (PCSI) mode, one or more semi-continuous measurement (SPCSI) modes.

[0233] For example, a SIBX may contain all sets of measurement parameters, or each SIBX may contain at most one set of measurement parameters, or a SIBX may contain all sets of measurement parameters corresponding to a detection capability.

[0234] For example, the communication module 1001 is used to receive a first message from a first terminal device, the first message including third indication information, the third indication information being used to indicate that the first terminal device has a first detection capability, the first detection capability being one of at least one detection capability; and to send a second message to the first terminal device, the second message being used to instruct the first terminal device to perform CSI-RS measurement according to a target parameter set, the target parameter set being one of at least one set of measurement parameters corresponding to the first detection capability.

[0235] For example, the second message includes at least one of the following indications: a target measurement mode and a target parameter set, wherein the measurement parameter set corresponding to the target measurement mode is the target parameter set; the target measurement mode is a measurement mode corresponding to the first detection capability among at least one measurement mode that the terminal device can support.

[0236] For example, the target parameter set is one of the sets of at least one set of measurement parameters that is in an unused state.

[0237] For example, the higher the detection capability, the more measurement parameters are associated with that detection capability. The target parameter set is the set of measurement parameters that the first detection capability has and that other detection capabilities below the first detection capability do not have.

[0238] For example, the second message also includes measurement window information, which indicates the time period during which the first terminal device performs CSI-RS measurements.

[0239] For example, the measurement window information includes at least one of the following: measurement start time, measurement duration, measurement end time, and measurement result reporting timing.

[0240] The above are merely examples; for detailed steps or procedures, please refer to the descriptions in the foregoing embodiments.

[0241] In one possible design, the communication device 1000 may correspond to the terminal device in the above method embodiments, or to a component (such as a circuit, chip, or chip system) configured in the terminal device. The communication device 1000 may be used to execute the steps or processes performed by the terminal device in any of the above method embodiments.

[0242] For example, the communication module 1001 is used to receive a system information block (SIB), wherein SIB1 includes first indication information and SIBX includes second indication information. The first indication information is used to indicate at least one detection capability of the Channel State Information Reference Signal (CSI-RS) that the terminal device can support, and the second indication information is used to indicate the set of measurement parameters for CSI-RS measurement corresponding to each detection capability.

[0243] For example, the processing module 1002 can be used to obtain at least one set of measurement parameters corresponding to the first terminal device based on the first indication information and the second indication information.

[0244] For example, the first indication information includes first data and second data. The first data includes capability parameters corresponding to each of the at least one detection capability, and the second data includes the correspondence between the detection capability and the set of measurement parameters. The processing module 1002 is specifically used to: determine the first detection capability corresponding to the first terminal device based on the capability parameters of the first terminal device and the first data; determine at least one set of parameters corresponding to the first detection capability based on the first detection capability and the second data; and read at least one set of parameters from the second indication information.

[0245] For example, the communication module 1001 is used to send a first message to the network device, the first message including indication information of a first detection capability; the processing module 1002 can be used to perform CSI-RS measurement according to the target parameter set indicated by the second message when a second message is received, the target parameter set being one of at least one set of measurement parameters corresponding to the first detection capability.

[0246] For example, the second message also includes measurement window information, which is used to indicate the time period for the first terminal device to perform CSI-RS measurement; the processing module 1002 is specifically used to: perform CSI-RS measurement according to the target parameter set within the time period indicated by the measurement window information.
