Description

Channel state information reporting configuration method and device Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] As 5G becomes more popular in various industries and applied in more geographical areas, in order to handle more advanced services, very high data rates and denser networks are required, using more antennas, larger bandwidths and more frequency bands. As a result, the energy consumption of 5G devices is becoming increasingly larger.

[0003] According to operator statistics, the average energy consumption of a 5G base station is more than three times that of an LTE base station. Nearly 50% of the cost of deploying a 5G network for operators comes from electricity costs. Furthermore, 5G base stations consume significant energy even during periods of inactivity. Therefore, network energy conservation is crucial for improving environmental sustainability, reducing environmental impact (such as greenhouse gas emissions), and saving operating costs. Energy conservation in 5G networks is an urgent issue that needs to be addressed.

[0004] To achieve network energy conservation, Rel-18 initiated a project to research various energy-saving technologies. During the discussion, network energy-saving technologies can be categorized into time-domain, frequency-domain, spatial-domain, and energy-domain energy conservation. Examples of spatial-domain energy conservation include dynamically adjusting the number of antennas, dynamically adjusting data transmission power, and introducing cell-based DTX / DRX technology. Using these various energy-saving technologies can significantly save energy for network equipment and / or terminal devices.

[0005] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0006] Summary of the Invention

[0007] However, the inventors have discovered that some wireless communication application scenarios (such as energy-saving mode) may have negative impacts. For example, when network devices dynamically adjust the number of antennas or transmission power, this may cause changes in the corresponding channels, resulting in inaccurate or untimely Channel State Information (CSI) measurement results or CSI reporting results from terminal devices, ultimately affecting transmission performance. How to accurately and timely configure CSI reporting for terminal devices, thereby accurately measuring and reporting CSI, is a key issue that needs to be addressed.

[0052] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0053] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0054] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101 and the terminal devices 102 and 103. For example, these services may include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0055] It is worth noting that FIG1 shows that both terminal devices 102 and 103 are within the coverage range of network device 101, but the present application is not limited thereto. Both terminal devices 102 and 103 may not be within the coverage range of network device 101, or one terminal device 102 may be within the coverage range of network device 101 while the other terminal device 103 is outside the coverage range of network device 101.

[0056] In the embodiments of the present application, the high-layer signaling may be, for example, radio resource control (RRC) signaling; for example, an RRC message, including, for example, an MIB, system information, or a dedicated RRC message; or an RRC information element (RRC IE). The high-layer signaling may also be, for example, MAC (Medium Access Control) signaling; or a MAC control element (MAC CE). However, the present application is not limited thereto.

[0057] In mobile communication systems, terminal devices typically measure CSI (channel state information) based on instructions and configuration from network devices and then report the measured CSI to the network devices. When scheduling the terminal device, the network device can refer to this CSI to schedule the terminal device for transmission using the appropriate physical resources and transmission method. Different terminal devices may experience different physical channel conditions. Using a CSI feedback mechanism can effectively utilize physical resources, thereby improving overall network transmission efficiency.

[0058] In the NR CSI feedback mechanism, the terminal device primarily measures and reports reference signals from the network device based on the CSI configuration. Reference signals include the Channel State Information Reference Signal (CSI-RS) and Synchronization Signal Block (SSB). The NR CSI configuration primarily includes: the resource configuration for CSI measurement configured by the network device for the terminal device (referred to as the CSI-RS resource configuration), and the reporting configuration that the network device uses to configure the terminal device for reporting (referred to as the CSI reporting configuration).

[0059] For example, the CSI-RS resource configuration mainly configures: the time-frequency-space resources of the CSI-RS resources, and the necessary parameters for generating the RS sequence. In short, the terminal device can accurately know the RS sequence sent by the network device and the specific time-frequency-space resource position of the sequence based on the CSI-RS resource configuration, so as to receive the sequence at the corresponding position and perform signal processing on the received sequence with the locally generated sequence as a reference to accurately estimate the channel. For specific information on how to generate the RS sequence, please refer to the relevant technology and will not be described in detail here. The embodiment of the present application will illustrate the CSI-RS resource configuration.

[0060] For each CSI-RS resource, the network device determines the time-frequency position through the following parameters in CSI-RS-ResourceMapping, as shown in Table 1 below.

[0061] Table 1

[0062] As shown in Table 1, firstOFDMSymbolInTimeDomain and firstOFDMSymbolInTimeDomain2 are used to determine the position of the CSI-RS resource in the time domain. Currently, NR supports occupying 1, 2 or 4 OFDM symbols; the frequencyDomainAllocation parameter is used to determine the position of the CSI-RS resource in the frequency domain; the nrofPorts parameter is used to determine the number of CSI-RS ports. Currently, NR supports configurations of 1, 2, 4, 8, 12, 16, 24 and 32 ports; the cdm-Type parameter is used to determine the code division multiplexing (CDM) type of the CSI-RS resource. Currently, NR supports three patterns: CDM-2, CDM-4 and CDM-8.

[0063] Figure 2 is a schematic diagram of a CDM pattern according to an embodiment of the present application. Taking CDM-4 as an example, the pattern includes four ports, each of which occupies all resource elements (REs) in the pattern, and the ports are distinguished by different orthogonal cover codes.

[0064] The REs occupied by a CDM pattern form a CDM group, and each CDM group contains 2, 4, or 8 ports. In this way, multiple CSI-RS ports can be distributed to multiple CDM groups with the same pattern. In other words, the CSI-RS port distribution can be determined by CDM group aggregation.

[0065] NR supports multiple flexible aggregation schemes. For the same port configuration, multiple CDM aggregation schemes are supported. NR utilizes CDM group aggregation using three CDM patterns: CDM-2, CDM-4, ​​and CDM-8, flexibly supporting CSI-RSs with 2 to 32 ports. For a multi-port CSI-RS resource, different ports may adopt various multiplexing methods.

[0066] Figure 3 is a schematic diagram of port multiplexing in accordance with an embodiment of the present application. As shown in Figure 3, a CDM+TDM approach is used. The CSI-RS resources of four ports are aggregated using a CDM-2 pattern and divided into two CDM groups. Each CSI-RS port within a CDM group is mapped to two REs within the pattern. Orthogonal multiplexing is achieved between ports using an orthogonal cover code (OCC) of length 2. The ports within the CDM groups (e.g., ports 0, 1 and ports 2, 3) are orthogonalized using TDM.

[0067] Figure 4 is another schematic diagram of port multiplexing in an embodiment of the present application. As shown in Figure 4, a CDM+FDM+TDM approach is used. The 24-port CSI-RS resources are aggregated using a CDM-4 pattern and divided into six CDM groups. Orthogonal multiplexing is achieved between the CSI-RS ports within each CDM group using OCCs of length 4. Orthogonal multiplexing is achieved between different CDM groups using TDM or FDM.

[0068] Currently, CSI-RS resource configuration is semi-statically configured via Radio Resource Control (RRC) signaling and generally remains unchanged for an extended period of time. If these resources need to be changed, they can be adjusted via RRC reconfiguration. However, some wireless communication application scenarios (such as energy-saving mode) may require adjustments to transmit power or the number of antennas, which may alter these resources.

[0069] Figure 5 is an example diagram of resource adjustment in an embodiment of the present application. For example, a network device initially configures an 8-port CSI-RS for a terminal device for channel measurement, etc. Subsequently, the network device readjusts the antenna configuration, for example, by turning off some antenna panels or some antenna factors. After the adjustment, the network device uses a 4-port CSI-RS to serve the terminal device. Due to the change in antenna configuration, the 8-port CSI-RS before the change and the 4-port CSI-RS after the change experience different channels.

[0070] This adjustment can be static or dynamic. Dynamic adjustments can achieve better power savings. These adjustments can be made at the slot level (for example, with a 15kHz subcarrier spacing, one slot is 1ms) or at the symbol level (for example, with a 15kHz subcarrier spacing, one symbol is approximately 71.4us).

[0071] When network devices dynamically adjust their configurations (for example, CSI-RS ports), the channel may experience a sudden change (discontinuity in the equivalent channel response at the receiver before and after the adjustment). In this case, if the existing CSI measurement and reporting mechanism is used, the terminal device will not be able to detect the sudden change and perform accurate measurement and reporting. In other words, the terminal device cannot accurately perform CSI measurement and reporting. Accordingly, the network device side also does not have accurate channel state information for scheduling decisions.

[0072] On the other hand, even if network devices are statically configured, existing CSI-RS resource configuration is terminal-specific. If the existing configuration mechanism is used, the network device may need to configure all terminal devices it serves one by one after each adjustment. Considering the overhead of RRC configuration, this may result in excessive signaling overhead, thereby affecting network transmission efficiency and reducing data transmission rate.

[0073] Therefore, how network devices can accurately and timely configure CSI reporting so that terminal devices can efficiently and accurately report CSI even when resources are adjusted (for example, for the purpose of energy saving) becomes a problem that needs to be solved.

[0074] In the embodiments of the present application, the reference signal is a CSI-RS. Reference signal resources may also be referred to as CSI-RS resources, and resource configuration may also be referred to as CSI-RS resource configuration. The present application is not limited thereto. Furthermore, the embodiments of the present application are described using energy conservation as an example, but are not limited thereto and are applicable to any scenario involving CQI calculation or CSI measurement.

[0075] Embodiments of the first aspect

[0076] The present application embodiment provides a CSI reporting configuration method, which is described from the perspective of a terminal device. FIG6 is a schematic diagram of the CSI reporting configuration method according to the present application embodiment. As shown in FIG6 , the method includes:

[0077] 601. A terminal device receives a first resource configuration, where the first resource configuration is at least used to configure a first reference signal resource of an M-port; and

[0078] 602, the terminal device receives a channel state information (CSI) reporting configuration; the channel state information (CSI) reporting configuration is used to configure the reporting of the first channel state information (CSI) and / or the second channel state information (CSI); wherein the first channel state information (CSI) is associated with the first reference signal resource of the M port, and the second channel state information (CSI) is associated with the second reference signal resource of the N port, where N is less than M.

[0079] It is worth noting that FIG6 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG6 above.

[0080] For example, the first resource configuration and the CSI reporting configuration may be carried by the same RRC signaling or by different RRC signaling. For another example, the first resource configuration and the CSI reporting configuration may be two different configurations or included in the same configuration. This embodiment of the present application does not limit this.

[0081] In an embodiment of the present application, a terminal device receives a channel state information (CSI) reporting configuration for configuring reporting of first channel state information (CSI) and / or second channel state information (CSI); the first channel state information (CSI) is associated with a first reference signal resource of an M-port, and the second channel state information (CSI) is associated with a second reference signal resource of an N-port. Thus, even when resources are adjusted (for example, for energy conservation), the terminal device can efficiently and accurately report CSI without increasing the number of channel state information (CSI) reporting configurations, thereby providing accurate channel information for scheduling of network devices.

[0082] In some embodiments, the channel state information (CSI) reporting configuration is per cell and / or per component carrier (per CC). For example, the CSI reporting configuration is different for different cells. For another example, the CSI reporting configuration is different for different CCs. The present application is not limited thereto.

[0083] In some embodiments, the channel state information (CSI) reporting may be periodic or semi-continuous.

[0084] In some embodiments, the first reference signal resource of the M-port and the second reference signal resource of the N-port are NZP CSI-RS resources used for channel measurement.

[0085] For example, one feasible solution for network energy conservation is dynamic port adjustment. Reference signal resources requiring dynamic port adjustment are non-zero-power CSI-RS resources based on channel measurements. Furthermore, CSI-RS resources based on TRS measurements (corresponding to the high-level parameter trs_info) and beam management (corresponding to the high-level parameter repetition configuration on or off) do not require port adjustment due to the relatively small number of ports.

[0086] In some embodiments, the first reference signal resource and / or the second reference signal resource are at least time domain resources and / or frequency domain resources and / or spatial domain resources used to send or receive reference signals.

[0087] In some embodiments, the second reference signal resource of the N-port is a portion of the first reference signal resource of the M-port.

[0088] For example, the second reference signal resource of the N-port is the time domain resource and / or frequency domain resource and / or spatial domain resource corresponding to some ports of the first reference signal resource of the M-port. In a network energy-saving scenario, the terminal device can be configured with more than one CSI-RS resource in the channel measurement resource set in the CSI reporting configuration (CSI-ReportConfig). An N-port second reference signal resource corresponds to a spatial element / port muting mode, or a spatial element / port configuration.

[0089] The following first describes how to determine the first reference signal resource of the M-port and the second reference signal resource of the N-port.

[0090] In some embodiments, the first parameter for configuring the first reference signal resource of the M ports includes at least one of the following parameters: the number of ports (nrofPort) M, a parameter for determining the time domain resource position, and a parameter for determining the frequency domain resource position.

[0091] For example, the parameter used to determine the time domain resource position is the time domain position information (firstOFDMSymbolInTimeDomain) of the first OFDM symbol included in the first reference signal resource, and the parameter used to determine the frequency domain resource position is the frequency domain allocation information (frequencyDomainAllocation) of the first reference signal resource.

[0092] In some embodiments, a terminal device determines a first reference signal resource for M ports based on a first resource configuration, where the value of M is determined by a parameter nrofPort. The first reference signal resource for M ports represents the time-frequency-space resources corresponding to all ports in the first resource configuration. The second reference signal resource for N ports can be determined based on the first reference signal resource for M ports.

[0093] Figure 7 is an example diagram of the first reference signal resource and the second reference signal resource of an embodiment of the present application. For example, ports 0 to 3 and ports 4 to 7 in the 8-port first reference signal resource correspond to different antenna panels and are independently powered. When the base station turns off the power switches corresponding to ports 0 to 3, the circuits corresponding to ports 4 to 7 continue to operate normally. The second resources of the 4 ports after turning off the antenna are the time-frequency-space resources corresponding to ports 4 to 7 of the first reference signal resources of the 8 ports before turning off the antenna. Therefore, the terminal device can determine the second reference signal resource of the N port by the time-frequency-space resources corresponding to a part of the ports of the first reference signal resource of the M port.

[0094] The following further describes how to determine the second reference signal resource of the N port.

[0095] In some embodiments, the terminal device determines the first reference signal resource of the M port based on the first parameter; and the terminal device determines the second reference signal resource of the N port based on the first parameter and second parameters, wherein the second parameter is included in the first resource configuration and / or the CSI reporting configuration.

[0096] In some embodiments, the second parameter is included in the first resource configuration, for example, under Resource Setting (e.g., CSI-ResourceMapping), or ResourceSet (e.g., nzp-CSI-ResourceSet), or Resource (e.g., nzp-CSI-Resource), or CSI-RS-ResourceMapping.

[0097] In some embodiments, the second parameter is included in the CSI reporting configuration, that is, included in CSI-ReportConfig.

[0098] In some embodiments, at least one second reference signal resource may be determined based on the first resource configuration. A second parameter is used to indicate that N ports of the M ports of the first reference signal resource are the second reference signal resources; or the second parameter indicates or enables resources corresponding to some ports of the M-port first reference signal resources as the N-port second reference signal resources.

[0099] For example, the second parameter is X bits, and the X bits are used to indicate N consecutive or discontinuous ports among the M ports. The X bits are indicated in a bitmap manner, for example.

[0100] For another example, a list of length L is predefined or preconfigured, each row in the list represents a value of N ports among the M ports, and the X bits are used to indicate the index of the list, where X=log2(L).

[0101] For another example, the second parameter is a SLIV parameter, which is used to represent the N consecutive ports in the M ports. For example, the second parameter is used to represent the starting port index and port length of the N consecutive ports. For example, it indicates {starting port index, number of ports / length}.

[0102] For another example, the second parameter is a value, and the value indicates that a portion of the first reference signal resources of the M-port is the second reference signal resources of the N-port.

[0103] For another example, the second parameter is a numerical value or a proportional value, and the numerical value or the proportional value indicates that a portion of the first reference signal resources of the M-port is the second reference signal resources of the N-port.

[0104] For another example, a second parameter, such as EsEnable, can be used for enabling. When the network device configures this parameter, it indicates that the second resource of the N-port is the resource corresponding to a portion of the first resource of the current M-port. The specific ports of the M-port that the N-port is can be determined by a pre-defined rule or pre-configuration (RRC configuration).

[0105] In some embodiments, the terminal device determines the first reference signal resource of the M port based on the first parameter; the terminal device determines the second reference signal resource of the N port based on the first parameter and a third parameter, wherein the third parameter is included in the second resource configuration.

[0106] For example, the third parameter includes CSI-RS resource configuration index information including the aforementioned second parameter and / or reference resource.

[0107] In some embodiments, the terminal device determines the first reference signal resource of the M port according to the first parameter; the terminal device determines the second reference signal resource of the N port according to the first parameter and a fourth parameter, and the fourth parameter is included in the second resource configuration.

[0108] For example, the fourth parameter is used to indicate the time-frequency position of the second reference signal resource of the N port, and at least includes: a parameter for determining the time domain position of the first OFDM symbol (firstOFDMSymbolInTimeDomain), a parameter for determining the time domain position of the second OFDM symbol (secondOFDMSymbolInTimeDomain); and a parameter for determining the frequency domain resource position (frequencyDomainAllocation).

[0109] In some embodiments, the first resource configuration, the second resource configuration or the channel state information (CSI) reporting configuration is carried through radio resource control (RRC) signaling and / or medium access control (MAC) control element (CE).

[0110] The above schematically illustrates reference signal resource configuration, etc., and on this basis, CSI reporting configuration and CSI reporting will be described. In the following description, the first reference signal resource of the M-port and the second reference signal resource of the N-port can be based on a single reference signal resource configuration (such as the first resource configuration described above) or two reference signal resource configurations (such as the first resource configuration and the second resource configuration described above, or two independent resource configurations). The first reference signal resource of the M-port and / or the second reference signal resource of the N-port are associated with the channel state information reporting configuration.

[0111] In some embodiments, the terminal device performs a first CSI measurement based on the first reference signal resource of the M-port to generate the first CSI; the terminal device performs a second CSI measurement based on the second reference signal resource of the N-port to generate the second CSI.

[0112] In some embodiments, the channel state information (CSI) reporting configuration includes first information, where the first information is used to configure or indicate a first reference signal resource of the M-port and / or a second reference signal resource of the N-port.

[0113] For example, the first information may be at least one of the aforementioned first parameter, second parameter, third parameter, and fourth parameter, or any combination of these parameters; however, the present application is not limited thereto. The first information is associated with the first resource configuration and / or the second resource configuration, for example, the first information is an index of the first resource configuration, or an index of the second resource configuration, and so on.

[0114] In some embodiments, the channel state information (CSI) reporting configuration further includes second information, where the second information is used to indicate the number of channel state information (CSI).

[0115] The embodiment of the present application supports one CSI report containing multiple CSIs.

[0116] In some embodiments, the multiple CSIs correspond to different CSI-RS port number configurations, that is, to different spatial element muting modes, or to different spatial element configurations. Alternatively, the multiple CSIs correspond to different downlink transmission power configurations, that is, to different energy domain element configurations.

[0117] In some embodiments, a CSI reporting setting (CSI-ReportConfig) includes multiple CSI configurations, each configuration corresponds to a CSI-RS port configuration, or each configuration corresponds to a spatial element muting mode, or each configuration corresponds to a spatial element configuration.

[0118] Alternatively, a CSI reporting setting (CSI-ReportConfig) includes multiple CSI configurations, each configuration corresponds to a downlink transmission power configuration, or each configuration corresponds to an energy domain element configuration.

[0119] For example, if the CSI report corresponds to at least 2 CSIs, the second information may be used to determine the number of CSIs included in the CSI report; if the CSI report only includes 1 CSI, the second information may be omitted.

[0120] For another example, when the number of CSI measurement resources included in the CSI reporting configuration is 1, the second information may be default, indicating that the number of CSI is 1; when the number of CSI measurement resources included in the CSI reporting configuration is greater than 1, based on predefined rules or pre-configuration information, the second information defaults to indicating that the number of CSI results is the same as the number of CSI measurement resources, or that the number of CSI is 1.

[0121] In some embodiments, the channel state information (CSI) reporting configuration further includes third information, where the third information is used to indicate a mapping relationship between the channel state information (CSI) and a channel state information (CSI) reference signal resource.

[0122] For example, when the CSI reporting configuration includes at least two CSI results, the third information is used to determine the mapping relationship between the CSI results and the CSI measurement resources. For example, in the CSI reporting configuration, the first information determines the first reference signal resource of the M port, the second reference signal resource of the L port, and the second reference signal resource of the S port, the second information determines the number of CSI results as 2, and the third information determines that the first CSI result is associated with the second reference signal resource of the L port, and the second CSI result is associated with the second reference signal resource of the S port.

[0123] For another example, when the number of CSI measurement resources included in the CSI reporting configuration is 1, the third information may be omitted. When the number of CSI measurement resources included in the CSI reporting configuration is greater than 1, and the number of resources is the same as the number of CSI results in the second information, a pre-defined rule may be used to determine the mapping relationship, such as a one-to-one correspondence based on the index value arranged from small to large. In this case, the third information may be omitted.

[0124] In some embodiments, the channel state information (CSI) reporting configuration further includes fourth information, where the fourth information is used to indicate a channel state information (CSI) feedback amount. The channel state information feedback amount indicated by the fourth information is different from the channel state information feedback amount corresponding to the first resource configuration.

[0125] For example, when the CSI reporting configuration includes at least two CSI results, the fourth information is used to determine the CSI feedback quantity (Report Quantity). For example, a CSI feedback quantity can be defined as CRI1-RI1-PMI1-PMI2-CQI1-CQI2, and the terminal device measures the first reference signal resource of the M port to obtain CRI1, RI1, PMI1, and CQI1, and measures the second reference signal resource of the N port to obtain PMI2 and CQI2. The CRI and RI results obtained by measuring the two resources are the same by default, so the terminal device only needs to report the CRI and RI corresponding to the first reference signal resource of the M port.

[0126] In some embodiments, the terminal device determines at least one of the following based on preset rules and / or predetermined parameters: the number of channel state information (CSI) reports, the mapping relationship between channel state information (CSI) reports and channel state information (CSI) reference signal resources, the channel state information (CSI) feedback quantity type, and the channel state information (CSI) domain mapping type.

[0127] For example, pre-defined information is used to determine a newly added CSI feedback quantity (Report Quantity). For example, a CSI feedback quantity can be defined as CRI1-RI1-PMI1-PMI2-CQI1-CQI2, indicating that the CSI report contains two CSI results, CRI1, RI1, PMI1, and CQI1 corresponding to the first CSI result, and PMI2 and CQI2 corresponding to the second CSI result.

[0128] For another example, pre-defined information is used to determine the CSI domain mapping order for newly added CSI feedback quantity types. If a new CSI feedback quantity is added, such as CRI1-RI1-PMI1-PMI2-CQI1-CQI2, the specific CSI domain mapping corresponding to the CSI feedback quantity should be specified, that is, the number of bits occupied by each feedback quantity, such as the number of bits occupied by CRI1, the number of bits occupied by RI1, and so on.

[0129] In some embodiments, the second reference signal resource of the N-port and / or the second CSI associated therewith may be configured via UE-specific signaling, or via cell-specific or group-specific signaling. The signaling may be, for example, RRC, MAC CE, or DCI.

[0130] Taking the above-mentioned second parameter as an example, the second parameter can indicate the second reference signal resource of N ports by means of a numerical value, a ratio, or an enable. The second parameter can be sent to multiple terminal devices simultaneously through a group-based RRC signaling, that is, the signaling is based on Cell-specific or Group UEs-specific. For example, the second parameter is used to represent a numerical value, a ratio, or an enable, without specifically indicating the number of ports. The second parameter values ​​of multiple terminal devices are exactly the same, and can be sent to multiple terminal devices through a group signaling.

[0131] The above description uses the second parameter as an example, but the present application is not limited thereto. For example, the group signaling may include one or any combination of the first to fourth parameters or the first to fourth information, or may further include parameters for selecting a predefined solution, etc. Through cell-specific signaling or group-specific signaling, the network device can configure multiple terminal devices at once, thereby saving signaling overhead.

[0132] The following further illustrates CSI reporting.

[0133] In some embodiments, the terminal device performs CSI reporting, and the CSI reporting includes the first channel state information and / or the second channel state information.

[0134] In some embodiments, when the first reference signal resource of the M-port and the second reference signal resource of the N-port overlap, the CSI report includes the first channel state information and the second channel state information.

[0135] For example, the second reference signal resource of the N-port is part of the first reference signal resource of the M-port, and both are based on the first resource configuration. The terminal device receives one CSI reporting configuration, which is associated with both the first reference signal resource of the M-port and the second reference signal resource of the N-port. The terminal device feeds back two CSI results based on the CSI reporting configuration: a measurement result based on the first reference signal resource of the M-port and a measurement result based on the second reference signal resource of the N-port.

[0136] In some embodiments, when the first reference signal resource of the M-port and the second reference signal resource of the N-port overlap, the CSI report includes the second channel state information.

[0137] For example, the second reference signal resource of the N-port is part of the first reference signal resource of the M-port, and both are based on the first resource configuration. The terminal device receives one CSI reporting configuration, and the first CSI reporting configuration is simultaneously associated with the first reference signal resource of the M-port and the second reference signal resource of the N-port. The terminal device feeds back one CSI result based on the CSI reporting configuration. For example, the terminal device can determine whether the CSI report contains a measurement result based on the first reference signal resource of the M-port or a measurement result based on the second reference signal resource of the N-port based on the indication information and / or predefined rules of the DCI.

[0138] In some embodiments, when the first reference signal resource of the M-port and the second reference signal resource of the N-port do not overlap, the CSI report includes the first channel state information and the second channel state information.

[0139] For example, the first reference signal resource of the M-port and the second reference signal resource of the N-port are based on two independent resource configurations. The terminal device receives one CSI reporting configuration, which is associated with both the first reference signal resource of the M-port and the second reference signal resource of the N-port. The terminal device feeds back two CSI results based on this CSI reporting configuration: a measurement result based on the first reference signal resource of the M-port and a measurement result based on the second reference signal resource of the N-port.

[0140] The above schematically illustrates how to report CSI, and the following schematically illustrates how to confirm, trigger or switch.

[0141] In some embodiments, the terminal device determines the first reference signal resource and the second reference signal resource of the M-port based on the RRC configuration, and determines that the CSI measurement resource is the M-port first resource and the N-port second resource. The terminal device can measure the two resources simultaneously, which means that the terminal device measures the resources corresponding to different port configurations of the same resource. The different port configurations correspond to different spatial element muting modes or spatial element configurations.

[0142] In some embodiments, the terminal device receives fifth information and / or sixth information; and based on the fifth information and / or sixth information, determines to use the first reference signal resource of the M port and / or the second reference signal resource of the N port to report channel state information (CSI).

[0143] For example, the fifth information is carried by downlink control information (DCI) and / or medium access control (MAC) control element (CE), the fifth information can be carried by UE-specific signaling, or by group common signaling, and the group common signal is used to send information to multiple terminal devices at the same time; the sixth information is carried by radio resource control (RRC) signaling and / or medium access control (MAC) control element (CE). The sixth information can be configured by UE-specific signaling, or by cell-specific or group-specific signaling.

[0144] Thus, the terminal device can determine, based on, for example, DCI, whether the CSI measurement resource is the M-port first resource, the N-port second resource, or the M-port first resource and the N-port second resource, or determine whether the terminal reports the first CSI, the second CSI, or both the first CSI and the second CSI. After configuring the first reference signal resource and the second reference signal resource through, for example, RRC, and then confirming, indicating, triggering, or switching through, for example, DCI, the network device can further dynamically instruct the terminal device to report CSI, making CSI reporting more efficient and accurate.

[0145] In some embodiments, the fifth information is used to indicate at least one of the following: network status, channel state information (CSI) measurement performed by the terminal device, channel state information (CSI) measurement performed by the terminal device using the first reference signal resource of the M port, channel state information (CSI) measurement performed by the terminal device using the second reference signal resource of the N port, CSI-RS resource update / adjustment / switching, CSI reporting configuration adjustment / switching, CSI-RS port adjustment, CSI-RS port activation / deactivation indication, CSI-RS port enable indication, CSI measurement adjustment, indication related to discontinuous reception, and indication related to discontinuous transmission.

[0146] The fifth information indicating the update / adjustment / switching of the channel state information report can be used to indicate the number of channel information reports after the update / adjustment / switching and / or the specific channel state information, where the specific channel state information is the first channel state information and / or the second state information.

[0147] In some embodiments, the sixth information is used to indicate at least one of the following: a network status-related timer / counter, a network status-related discontinuous reception cycle configuration, and a network status-related discontinuous transmission cycle configuration.

[0148] In some embodiments, the network status indicates at least one of the following: first mode, second mode, switching from first mode to second mode, switching from second mode to first mode, time domain element adjustment, spatial domain element adjustment, energy domain element adjustment.

[0149] For example, the first mode is at least one of the following: energy-saving mode, power-saving mode, sleep mode, abnormal mode, non-activated mode, mode after the network device adjusts the CSI-RS port, and the first configuration mode of the CSI-RS port; the second mode is at least one of the following: non-energy-saving mode, non-power-saving mode, non-sleep mode, normal mode, activated mode, mode before the network device adjusts the CSI-RS port, and the second configuration mode of the CSI-RS port.

[0150] For another example, the spatial domain element indicates at least one of the following: antenna port, logical port, reference signal port, antenna factor, antenna element, and antenna unit. The energy domain element indicates at least one of the following: energy per resource element of a physical downlink shared channel (PDSCH) and energy per resource element of a channel state information reference signal.

[0151] The fifth information can be used in scenarios involving dynamic antenna element adjustment within network energy-saving technologies, and the sixth information can be used in scenarios involving semi-continuous or semi-static antenna element adjustment within network energy-saving technologies. In these scenarios, the fifth and / or sixth information can be used to indicate / switch CSI, that is, to indicate / switch antenna element muting modes / schemes.

[0152] For example, in a network energy-saving scenario, the base station is configured with a first CSI, a second CSI, a third CSI, and a fourth CSI, respectively, and associated with 32-port, 16-port, 8-port, and 4-port CSI-RSs, respectively. The 32-port CSI-RS is a first resource (referred to as resource 1), and the 16-port, 8-port, and 4-port CSI-RSs are second resources (referred to as resource 2, resource 3, and resource 4, respectively). The first CSI, the second CSI, the third CSI, and the fourth CSI correspond to different antenna element muting modes / configurations / mechanisms, respectively. The antenna element muting can be replaced by port muting, antenna on / off switching, and the like.

[0153] The terminal device can perform CSI measurement based on the 32-port CSI-RS and report the first CSI, or the terminal device can simultaneously perform CSI measurement based on the 32-port, 16-port, 8-port and 4-port CSI-RS and report the first CSI, second CSI, third CSI and fourth CSI.

[0154] The fifth information and / or the sixth information are used for switching CSI. For example, in the initial state, the terminal reports the CSI corresponding to the 32-port CSI-RS; the terminal device receives the fifth information (DCI signaling 1), and the DCI signaling 1 instructs the terminal to report 2 CSIs, namely the second CSI and the third CSI, and the terminal device reports the second CSI and the third CSI; after a period of time, the terminal receives the fifth information (DCI signaling 2), and the DCI signaling 2 instructs the terminal device to report 3 CSIs, namely the second CSI, the third CSI and the fourth CSI, and the terminal device reports the second CSI, the third CSI and the fourth CSI.

[0155] Alternatively, in the initial state, the terminal reports the CSI corresponding to the 32-port CSI-RS; the terminal device obtains the sixth information (timer expires or restarts), and based on the pre-defined rule or pre-configured information, the terminal device reports the second CSI and the third CSI; after a certain period of time, the terminal obtains the sixth information (timer restarts or expires), and the terminal device reports the first CSI.

[0156] The first CSI, the second CSI, the third CSI and the fourth CSI may be included in the same CSI reporting configuration (CSI-ReportConfig) or in different CSI reporting configurations (CSI-ReportConfig).

[0157] For example, the fifth information is carried based on DCI signaling. When the first CSI, second CSI, third CSI, and fourth CSI are respectively included in different CSI reporting configurations, the fifth information is used to simultaneously activate / deactivate multiple different semi-continuous or aperiodic CSI reports, which saves DCI signaling overhead compared to the existing technology. When the first CSI, second CSI, third CSI, and fourth CSI are included in the same CSI reporting configuration, the fifth information is used to indicate the number and specific CSI included in the CSI reporting configuration.

[0158] In some embodiments, the second reference signal resource of the N-port may also be a zero value, that is, the network device does not send a CSI-RS. When the terminal device obtains the fifth information and / or the sixth information, the terminal device does not receive a CSI-RS and does not perform any CSI measurement or CSI reporting.

[0159] For example, when the terminal device receives the fifth information or obtains the sixth information (timer expiration), the terminal device knows that the network device does not send a CSI-RS signal and performs skip processing or muting processing. The terminal device does not receive the CSI-RS signal and does not perform CSI measurement and CSI reporting.

[0160] In some embodiments, the fifth information may be carried using existing signaling, for example, DCI signaling that triggers PUSCH-based semi-persistent CSI reporting or aperiodic CSI reporting, or new signaling may be defined.

[0161] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0162] As can be seen from the above embodiment, the terminal device receives a channel state information (CSI) reporting configuration for configuring the reporting of first channel state information (CSI) and / or second channel state information (CSI); the first channel state information (CSI) is associated with the first reference signal resource of the M port, and the second channel state information (CSI) is associated with the second reference signal resource of the N port. As a result, even when resources are adjusted (for example, for the purpose of energy saving), the terminal device can efficiently and accurately report CSI without increasing the number of channel state information (CSI) reporting configurations, thereby providing accurate channel information for the scheduling of network devices.
