Description

[Technical Field]

[0001] The present invention relates to the field of communications. [Background technology]

[0002] As 5G becomes more widespread in various industries and applied to wider areas, it requires much higher data rates, denser networks, more antennas, wider bandwidth, and more frequency bands to handle more advanced services, which leads to higher energy consumption of 5G equipment.

[0003] According to data statistics from telecommunications carriers, the average energy consumption of a single 5G base station is more than three times that of an LTE base station, and electricity costs account for approximately 50% of the cost of deploying 5G networks for telecommunications carriers. More importantly, 5G base stations still have a significant energy consumption overhead even during periods when there is no traffic (business / service). Therefore, network energy conservation (energy savings) is crucial for improving environmental sustainability, reducing environmental impact (e.g., reducing greenhouse gas emissions), and saving operational costs. Therefore, energy conservation in 5G networks is an issue that must be addressed urgently.

[0004] To achieve network energy conservation, Rel-18 has set up a network energy conservation agenda to research various energy conservation technologies. In the discussion, network energy conservation technologies can be categorized into types such as time domain, frequency domain, space domain, and energy domain energy conservation. Space domain energy conservation, for example, is dynamic adjustment of the number of antennas. Energy domain energy conservation, for example, is dynamic adjustment of data transmission power. Time domain energy conservation, for example, is the introduction of cell DTX / DRX technology. By utilizing various energy conservation technologies, significant energy savings can be achieved in network equipment and / or terminal devices.

[0005] It should be noted that the introduction of the above background art is intended to clearly and completely explain the technical solutions of the present invention and to facilitate understanding by those skilled in the art, and these technical solutions described in the background art of the present invention should not be construed as being well known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0006] However, the inventors have discovered that in some scenarios of wireless communication applications (e.g., energy-saving mode), adverse effects may occur. For example, when a network device dynamically adjusts the number of antennas or transmission power, this may cause corresponding channel changes, which may result in inaccurate or delayed Channel State Information (CSI) measurement results or CSI reporting results from a terminal device, ultimately affecting transmission performance. How a terminal device can accurately and timely configure CSI reporting settings to accurately measure and report CSI is currently an important problem that needs to be solved.

The term "base station" may also include some or all of the functionality thereof, and each base station can provide communication coverage for a particular geographic area. The term "cell" may refer to a base station and / or the area it covers, depending on the context in which the term is used.

[0023] In embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that accesses a communication network and receives services from the network, for example, via network equipment. User equipment may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), a station, etc.

[0024] User equipment may include, but is not limited to, cellular phones, personal digital assistants (PDAs), wireless modems, wireless communication devices, mobile devices, machine-type communication devices, laptop computers, cordless phones, smartphones, smart watches, digital cameras, and the like.

[0025] Furthermore, for example, in the case of a scenario such as the Internet of Things (IoT), the user equipment may also be a monitoring or measuring device or apparatus, including, but not limited to, a Machine Type Communication (MTC) terminal, an in-vehicle communication terminal, a Device to Device (D2D) terminal, a Machine to Machine (M2M) terminal, etc.

Unless otherwise specified, "equipment" may refer to either network equipment or terminal equipment.

[0027] Hereinafter, the scenario of the embodiment of the present invention will be described through an example, but the present invention is not limited thereto.

[0028] 1 is a diagram showing a communication system in an embodiment of the present invention, taking terminal devices and network devices as an example. As shown in FIG. 1, communication system 100 may include network device 101 and terminal devices 102 and 103. For convenience, FIG. 1 illustrates an example in which only two terminal devices and one network device are used, but the embodiment of the present invention is not limited to this.

[0029] In an embodiment of the present invention, legacy or future traffic may be carried between the network device 101 and the terminal devices 102 and 103. For example, this traffic may include, but is not limited to, enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mMTC), Ultra-Reliable and Low-Latency Communication (URLLC), etc.

[0030] 1 shows that both of the two terminal devices 102 and 103 are within the coverage of the network device 101, but the present invention is not limited to this. Neither of the two terminal devices 102 and 103 may be located within the coverage of the network device 101, or one terminal device 102 may be located within the coverage of the network device 101 and the other terminal device 103 may be located outside the coverage of the network device 101.

[0031] In an embodiment of the present invention, the higher layer signaling may be, for example, Radio Resource Control (RRC) signaling, for example, referred to as an RRC message, including, for example, MIB, system information, and dedicated RRC messages, or referred to as an RRC information element (RRC IE). The higher layer signaling may also be, for example, Medium Access Control (MAC) signaling, or referred to as a MAC control element (MAC CE). However, the present invention is not limited thereto.

[0032] In a mobile communication system, a terminal device typically performs CSI (Channel State Information) measurement based on instructions and settings from a network device, and then reports the measured CSI to the network device. When scheduling the terminal device, the network device can refer to the CSI to adopt an appropriate transmission method with appropriate physical resources to schedule transmission for the terminal device. Different terminal devices may experience different physical channel conditions, and the CSI feedback mechanism can be used to rationally and effectively utilize physical resources, thereby improving the transmission efficiency of the entire network.

[0033] In the NR CSI feedback mechanism, the terminal device mainly measures and reports reference signals from the network device based on the CSI configuration, where the reference signals include a channel state information reference signal (CSI-RS), a synchronization signal block (SSB), etc. The NR CSI configuration mainly includes the following: a resource configuration for CSI measurement configured by the network device for the terminal device (which may also be referred to as a CSI-RS resource configuration), and a reporting configuration configured by the network device regarding how the terminal device reports (which may also be referred to as a CSI reporting configuration).

[0034] For example, the CSI-RS resource configuration mainly configures the following: the time-frequency-spatial domain resources of the CSI-RS resource, and the parameters required for generating the RS sequence. In short, based on the CSI-RS resource configuration, the terminal device can accurately determine the RS sequence transmitted by the network device and the specific time-frequency-spatial domain resource location of the sequence. Therefore, the terminal device can receive the sequence at the corresponding location and perform signal processing on the received sequence using the locally generated sequence as a reference, thereby accurately estimating the channel. For details on how to generate the RS sequence, please refer to the related art, and a detailed description thereof will be omitted here. In the embodiments of the present invention, the CSI-RS resource configuration is described.

[0035] For the time-frequency location of each CSI-RS resource, the network device determines it according to the following parameters in CSI-RS-ResourceMapping, as shown in Table 1 below:

[0036] [Table 1] As shown in Table 1, the firstOFDMSymbolInTimeDomain and firstOFDMSymbolInTimeDomain2 are used to determine the location of the CSI-RS resource in the time domain, and currently NR supports occupying one, two, or four orthogonal frequency division multiplexing (OFDM) symbols. The frequencyDomainAllocation parameter is used to determine the location of the CSI-RS resource in the frequency domain, and the nrofPorts parameter is used to determine the number of CSI-RS ports, and currently NR supports settings 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, and currently NR supports three patterns: CDM-2, CDM-4, ​​and CDM-8.

[0037] 2 shows a CDM pattern in an embodiment of the present invention. Taking CDM-4 as an example, the pattern includes four ports, each of which occupies all of the resource elements (REs) in the pattern, and the ports are differentiated by using different orthogonal cover codes.

[0038] The REs occupied by one CDM pattern constitute one CDM group, and each CDM group includes 2, 4, or 8 ports. Thus, multiple ports of the CSI-RS can be distributed among multiple CDM groups of the same pattern, i.e., the port distribution of the CSI-RS can be determined by the aggregation of the CDM groups.

[0039] NR supports multiple flexible aggregation schemes, and multiple CDM aggregation schemes are supported for the same type of port count configuration. NR flexibly supports CSI-RS for 2 to 32 ports by using aggregation of CDM groups of three CDM patterns: CDM-2, CDM-4, ​​and CDM-8. For one type of multi-port CSI-RS resource, multiple multiplexing methods may be adopted between different ports.

[0040] 3 is a diagram illustrating port multiplexing in an embodiment of the present invention. As shown in FIG. 3, a CDM+TDM scheme is used, in which four CSI-RS resources are aggregated using a CDM-2 pattern and divided into two CDM groups. Each CSI-RS port in the CDM group is mapped to two REs in the pattern. Orthogonal multiplexing between ports is achieved by an orthogonal cover code (OCC) of length 2. Ports between the CDM groups (e.g., ports 0 and 1 and ports 2 and 3) are orthogonalized by TDM.

[0041] Figure 4 is another diagram illustrating port multiplexing in an embodiment of the present invention. As shown in Figure 4, a CDM+FDM+TDM scheme is used, in which 24 CSI-RS resources are aggregated using a CDM-4 pattern and divided into six CDM groups. Orthogonal multiplexing between CSI-RS ports within each CDM group is achieved by an OCC of length 4. Orthogonal multiplexing between different CDM groups is achieved by TDM or FDM.

[0042] Currently, CSI-RS resource configurations are semi-statically configured by Radio Resource Control (RRC) signaling and generally do not change over a relatively long period of time. When these resources need to be changed, they can be adjusted by RRC reconfiguration. However, in some wireless communication application scenarios (e.g., energy saving mode), these resources may be changed due to the possibility of adjusting the transmission power, the number of antennas, etc.

[0043] 5 is a diagram illustrating an example of resource adjustment in an embodiment of the present invention. For example, a network device first configures eight CSI-RSs for one terminal device for channel measurement, etc. After that, the network device readjusts the antenna configuration, for example, turning off some antenna panels or some antenna elements. After the adjustment, the network device provides service to the terminal device using four CSI-RSs. Due to the change in antenna configuration, the channels traversed by the eight CSI-RSs before the change and the four CSI-RSs after the change are different.

[0044] Such adjustments may be relatively static or relatively dynamic. In comparison, relatively dynamic adjustments can achieve better power saving effects. Such relatively dynamic adjustments may be performed at the slot level (for example, with a subcarrier spacing of 15 kHz, one slot is 1 ms) or at the symbol level (for example, with a subcarrier spacing of 15 kHz, one symbol is approximately 71.4 μs).

[0045] When network equipment dynamically adjusts settings (e.g., CSI-RS port), sudden changes in the channel may occur (the equivalent channel response on the receiver side before and after adjustment becomes discontinuous). In such cases, if the existing CSI measurement and reporting mechanism is used, the terminal equipment will not be able to detect the sudden changes and therefore will not be able to perform accurate measurements and reports. In other words, the terminal equipment will not be able to accurately measure and report CSI, and accordingly, the network equipment will not have accurate channel state information for scheduling decisions.

[0046] In addition, even if the network device performs relatively static configuration, the existing CSI-RS resource configuration is dedicated to the terminal device. Therefore, if the existing configuration mechanism is adopted, the network device may need to perform configuration for each terminal device it serves one by one after each adjustment. In this way, considering the overhead of RRC configuration, the signaling overhead may be too large, which may affect network transmission efficiency and reduce the data transmission rate.

[0047] Therefore, one problem that needs to be solved is how to enable network devices to configure CSI reporting accurately and in a timely manner, and enable terminal devices to report CSI efficiently and accurately even in the case of resource adjustment (e.g., for the purpose of energy saving).

[0048] In the embodiments of the present invention, the reference signal is taken as an example of CSI-RS, and the reference signal resource may be referred to as a CSI-RS resource and the resource configuration may be referred to as a CSI-RS resource configuration, but the present invention is not limited thereto. Also, the embodiments of the present invention are described using energy saving as an example, but are not limited thereto and may be applied to any scenario involving CQI calculation or CSI measurement.

[0049] <Example of the first aspect> In an embodiment of the present invention, a CSI reporting configuration method is provided, which will be described from the terminal device side. Figure 6 is a diagram showing a CSI reporting configuration method in an embodiment of the present invention. As shown in Figure 6, the method includes: 601: A terminal device receives a first resource configuration, and the first resource configuration is used to configure at least a first reference signal resource of an M port; and 602: The terminal device receives a channel state information (CSI) reporting configuration, the channel state information (CSI) reporting configuration is used to configure reporting of first channel state information (CSI) and / or second channel state information (CSI), in which the first channel state information (CSI) is associated with a first reference signal resource of the M port and the second channel state information (CSI) is associated with a second reference signal resource of the N port, in which N is less than M.

[0050] Note that the above-mentioned FIG. 6 is merely an illustrative example of an embodiment of the present invention, and the present invention is not limited thereto. For example, the execution order of each operation may be appropriately adjusted, or some operations may be appropriately added or removed. Those skilled in the art may make appropriate modifications based on the above content, without being limited to the description of the above-mentioned FIG. 6.

[0051] For example, the first resource configuration and the CSI reporting configuration may be carried by the same RRC signaling or may be carried by different RRC signaling. Also, for example, the first resource configuration and the CSI reporting configuration may be two different configurations or may be included in the same configuration. This is not a limitation in the embodiments of the present invention.

[0052] In an embodiment of the present invention, a terminal device receives a channel state information (CSI) reporting configuration to configure reporting of first channel state information (CSI) and / or second channel state information (CSI), where the first channel state information (CSI) is associated with a first reference signal resource of M ports and the second channel state information (CSI) is associated with a second reference signal resource of N ports. This allows the terminal device to efficiently and accurately report CSI without additionally increasing the number of channel state information (CSI) reporting configurations in the case of resource adjustment (e.g., for the purpose of energy saving), thereby providing accurate channel information for scheduling by a network device.

[0053] In some embodiments, the channel state information (CSI) reporting configuration is per cell and / or per component carrier. For example, the CSI reporting configuration may be different for different cells. Also, for example, the CSI reporting configuration may be different for different CCs. However, the present invention is not limited thereto.

[0054] In some embodiments, the channel state information (CSI) reporting may be periodic or semi-persistent.

[0055] In some embodiments, the first reference signal resource of the M ports and the second reference signal resource of the N ports are NZP CSI-RS resources for channel measurement.

[0056] For example, one feasible scheme for network energy conservation is dynamic port adjustment. Reference signal resources for which port adjustment is required are non-zero-power CSI-RS resources based on channel measurement. Furthermore, CSI-RS resources based on TRS measurement (corresponding to the upper layer parameter trs_info) and beam management (corresponding to the upper layer parameter repetition setting on or off) do not require port adjustment operations because the number of ports is relatively small.

[0057] In some embodiments, the first reference signal resource and / or the second reference signal resource is at least a time domain resource and / or a frequency domain resource and / or a spatial domain resource for transmitting or receiving a reference signal.

[0058] In some embodiments, the second reference signal resource of the N ports is a portion of the first reference signal resource of the M ports.

[0059] For example, the second reference signal resources of the N ports are time domain resources and / or frequency domain resources and / or spatial domain resources corresponding to some of the first reference signal resources of the M ports. In a network energy saving scenario, a terminal device may be configured with multiple CSI-RS resources in a channel measurement resource set in a CSI reporting configuration (CSI-ReportConfig). One type of second reference signal resource of the N ports corresponds to one type of spatial domain element / port muting mode or one type of spatial domain element / port configuration.

[0060] The following describes how to determine the first reference signal resource of the M port and the second reference signal resource of the N port.

[0061] 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: a number of ports (nrofPort) M, a parameter for determining the location of time domain resources, and a parameter for determining the location of frequency domain resources.

[0062] For example, the parameter for determining the time domain resource location is the time domain location information (firstOFDMSymbolInTimeDomain) of the first OFDM symbol included in the first reference signal resource, and the parameter for determining the frequency domain resource location is the frequency domain allocation information (frequencyDomainAllocation) of the first reference signal resource.

[0063] In some embodiments, the terminal device determines first reference signal resources for M ports based on the first resource configuration, where the value of M is determined by a parameter nrofPort, and the first reference signal resources for M ports represent time-frequency-spatial domain resources corresponding to all ports in the first resource configuration. The second reference signal resources for N ports can be determined by the first reference signal resources for M ports.

[0064] 7 is a diagram illustrating an example of first reference signal resources and second reference signal resources in an embodiment of the present invention. For example, ports 0 to 3 and ports 4 to 7 of the first reference signal resources of eight ports correspond to different antenna panels and are powered independently. When the base station turns off the power switches corresponding to ports 0 to 3, the circuits corresponding to ports 4 to 7 can still work normally. The second resources of the four ports after the antennas are turned off are the time-frequency-spatial domain resources corresponding to ports 4 to 7 of the first reference signal resources of the eight ports before the antennas are turned off. Therefore, the terminal device can determine the second reference signal resources of the N ports based on the time-frequency-spatial domain resources corresponding to some ports of the first reference signal resources of the M ports.

[0065] The following describes how to determine the second reference signal resource of an N port.

[0066] In some embodiments, the terminal device determines first reference signal resources for the M ports based on the first parameter, and determines second reference signal resources for the N ports based on the first parameter and a second parameter, wherein the second parameter is included in the first resource configuration and / or the CSI reporting configuration.

[0067] In some embodiments, the second parameter is included in the first resource configuration, and may be included in, for example, a Resource Setting (e.g., CSI-ResourceMapping), or a ResourceSet (e.g., nzp-CSI-ResourceSet), or a Resource (e.g., nzp-CSI-Resource), or a CSI-RS-ResourceMapping.

[0068] In some embodiments, the second parameter is included in a CSI reporting configuration, CSI-ReportConfig.

[0069] In some embodiments, at least one second reference signal resource can be determined based on the first resource configuration, and the second parameter is used to indicate that N ports among the M ports of the first reference signal resource are the second reference signal resources, or the second parameter is used to indicate or enable resources corresponding to some ports among the first reference signal resources of the M ports as second reference signal resources of the N ports.

[0070] For example, the second parameter may be X bits, and the X bits may be used to indicate N consecutive or non-consecutive ports among the M ports, for example, in the form of a bitmap.

[0071] Also, for example, a list of length L is predefined or preset, each row in the list represents one value of N ports among the M ports, and the X bits are used to indicate an index into the list, where X=log2(L).

[0072] Also, for example, the second parameter is a Start and Length Indicator (SLIV) parameter, and the SLIV parameter is used to indicate consecutive N ports among the M ports. For example, the second parameter is used to indicate the index of the starting port of the consecutive N ports and the length (number) of ports. For example, it indicates {starting port index, number of ports / length}.

[0073] Also, for example, the second parameter is one value, and the value indicates that some of the first reference signal resources of the M ports are second reference signal resources of the N ports.

[0074] Also, for example, the second parameter is a numerical value or a proportional value, and the numerical value or proportional value indicates that some of the first reference signal resources of the M ports are second reference signal resources of the N ports.

[0075] Furthermore, for example, the second parameter may be used for enabling, for example, EsEnable, and indicates that the second resource of the N port corresponds to a part of the first resource of the current M port when the network device sets the parameter. Specifically, which port of the M port the N port corresponds to may be determined by a pre-defined rule method or a pre-configuration (RRC configuration) method.

[0076] In some embodiments, the terminal equipment determines a first reference signal resource for the M port based on the first parameter, and the terminal equipment determines a second reference signal resource for the N port based on the first parameter and a third parameter, wherein the third parameter is included in the second resource configuration.

[0077] For example, the third parameter includes CSI-RS resource configuration index information including the second parameter and / or the reference resource.

[0078] In some embodiments, the terminal equipment determines a first reference signal resource for the M port based on the first parameter, and the terminal equipment determines a second reference signal resource for the N port based on the first parameter and a fourth parameter, the fourth parameter being included in the second resource configuration.

[0079] For example, the fourth parameter is used to indicate the time-frequency location of the second reference signal resource of the N port, and specifically includes at least a parameter (firstOFDMSymbolInTimeDomain) for determining the time-domain location of the first OFDM symbol, a parameter (secondOFDMSymbolInTimeDomain) for determining the time-domain location of the second OFDM symbol, and a parameter (frequencyDomainAllocation) for determining the frequency-domain resource location.

[0080] In some embodiments, the first resource configuration, the second resource configuration, or the channel state information (CSI) reporting configuration is carried by radio resource control (RRC) signaling and / or a medium access control (MAC) control element (CE).

[0081] The above describes reference signal resource configurations, etc., by way of example, and the CSI reporting configuration and CSI report will be described based on this. In the following description, the first reference signal resource of M ports and the second reference signal resource of N ports may be based on one reference signal resource configuration (e.g., the first resource configuration described above) or two reference signal resource configurations (e.g., the first resource configuration and the second resource configuration described above, or two independent resource configurations), and the first reference signal resource of M ports and / or the second reference signal resource of N ports are associated with a channel state information reporting configuration.

[0082] In some embodiments, the terminal device generates the first CSI by performing a first CSI measurement based on a first reference signal resource of the M port, and the terminal device generates the second CSI by performing a second CSI measurement based on a second reference signal resource of the N port.

[0083] In some embodiments, the channel state information (CSI) reporting configuration includes first information, which 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.

[0084] For example, the first information may be at least one of the first parameter, the second parameter, the third parameter, and the fourth parameter, or any combination of these parameters, but the present invention is not limited thereto. The first information is associated with the first resource configuration and / or the second resource configuration, and for example, the first information may be an index of the first resource configuration or an index of the second resource configuration.

[0085] In some embodiments, the channel state information (CSI) reporting configuration further includes second information, and the second information is used to indicate the number of channel state information (CSI).

[0086] The embodiment of the present invention supports including multiple CSIs in one CSI report.

[0087] In some embodiments, the multiple CSIs correspond to different CSI-RS port number configurations, i.e., different spatial domain element muting modes, or different spatial domain element configurations, or the multiple CSIs correspond to different downlink transmission power configurations, i.e., different energy domain element configurations.

[0088] In some embodiments, one CSI reporting configuration (CSI-ReportConfig) includes multiple CSI configurations, each corresponding to one type of CSI-RS port configuration, or each corresponding to one type of spatial domain element muting mode, or each corresponding to one type of spatial domain element configuration.

[0089] Alternatively, one CSI reporting configuration (CSI-ReportConfig) includes multiple CSI configurations, each corresponding to one type of downlink transmission power configuration, or each corresponding to one type of energy region element configuration.

[0090] For example, when there are at least two CSIs corresponding to a CSI report, the second information can be used to determine the number of CSIs included in the CSI report, and when there is only one CSI in the CSI report, the second information can be omitted.

[0091] Also, for example, when the number of CSI measurement resources included in the CSI reporting configuration is 1, the second information may be a default and indicate that the number of CSIs is 1. When the number of CSI measurement resources included in the CSI reporting configuration is greater than 1, the second information indicates by default that the number of CSI results is the same as the number of CSI measurement resources, or the number of CSIs is 1, based on a predefined rule or preconfigured information.

[0092] In some embodiments, the channel state information (CSI) reporting configuration further includes third information, which is used to indicate a mapping relationship between the channel state information (CSI) and the channel state information (CSI) reference signal resource.

[0093] For example, when the CSI reporting configuration includes at least two CSI results, the third information is used to determine a mapping relationship between the CSI results and the CSI measurement resources. For example, in the CSI reporting configuration, the first information determines a first reference signal resource for M ports, a second reference signal resource for L ports, and a second reference signal resource for S ports, the second information determines that the number of CSI results is two, and the third information is used to determine that the first CSI result is associated with the second reference signal resource for L ports and the second CSI result is associated with the second reference signal resource for S ports.

[0094] Furthermore, for example, when the number of CSI measurement resources included in the CSI reporting configuration is 1, the third information may be default. 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 mapping relationship may be determined according to a pre-defined rule, for example, arranged in order from smallest to largest index value, with one-to-one correspondence, and in this case, the third information may be default.

[0095] In some embodiments, the channel state information (CSI) reporting configuration further includes fourth information, the fourth information being used to indicate a channel state information (CSI) feedback amount, the channel state information feedback amount indicated by the fourth information being different from the channel state information feedback amount corresponding to the first resource configuration.

[0096] 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, one CSI feedback quantity may be defined as CRI1-RI1-PMI1-PMI2-CQI1-CQI2, where the terminal device measures the first reference signal resource of port M to obtain CRI1, RI1, PMI1, and CQI1, measures the second reference signal resource of port N to obtain PMI2 and CQI2, and implicitly considers that the CRI and RI results obtained by measuring the two resources are the same. Therefore, the terminal device only needs to report the CRI and RI corresponding to the first reference signal resource of port M.

[0097] In some embodiments, the terminal device determines at least one of the following based on a predetermined rule and / or predetermined parameters: the number of CSI reports, the mapping relationship between the CSI reports and the CSI reference signal resources, the CSI feedback amount type, and the CSI field mapping type.

[0098] For example, the predefined information is used to determine a newly added CSI feedback quantity (Report Quantity). For example, one CSI feedback quantity may be defined as CRI1-RI1-PMI1-PMI2-CQI1-CQI2, which means that the CSI report includes two CSI results, where CRI1, RI1, PMI1, and CQI1 correspond to the first CSI result, and PMI2 and CQI2 correspond to the second CSI result.

[0099] Furthermore, for example, the predefined information is used to determine the CSI domain mapping order of newly added CSI feedback quantity (Report Quantity) types. When a new CSI feedback quantity is added, for example, when CRI1-RI1-PMI1-PMI2-CQI1-CQI2 is newly added, a specific CSI domain mapping situation corresponding to the CSI feedback quantity should be described, that is, the number of bits occupied by each type of feedback quantity, for example, the number of bits occupied by CRI1, the number of bits occupied by RI1, etc.

[0100] In some embodiments, the second reference signal resource of the N-port and / or the second CSI associated therewith may be configured by UE-specific signaling, or may be configured by cell-specific or group-specific signaling, such as RRC, MAC CE, DCI, etc.

[0101] Taking the above-mentioned second parameter as an example, for example, the second parameter can indicate the second reference signal resources of N ports in the form of a numerical value, a proportional value, or an enable. The second parameter can be simultaneously transmitted to multiple terminal devices through one 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 indicate a numerical value, a proportional value, or an enable, and does not need to specifically indicate the number of ports. The second parameter values ​​of multiple terminal devices are exactly the same, and can be transmitted to multiple terminal devices through one set of signaling.

[0102] Although the above description has been given taking the second parameter as an example, the present invention is not limited thereto, and for example, a set of signaling may include one or any combination of the above-mentioned first to fourth parameters and the first to fourth information, or may further include a parameter for selecting a predefined scheme, etc. Cell-specific signaling or group-specific signaling allows a network device to configure multiple terminal devices at once, thereby saving signaling overhead.

[0103] The CSI report will be described below as an example.

[0104] In some embodiments, the terminal device performs a CSI report, and the CSI report includes the first channel state information and / or the second channel state information.

[0105] 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.

[0106] For example, the second reference signal resources of N ports are part of the first reference signal resources of M ports, and both are configured based on the first resources. The terminal device receives one CSI reporting configuration, and the CSI reporting configuration is simultaneously associated with the first reference signal resources of M ports and the second reference signal resources of N ports. The terminal device feeds back two CSI results based on the CSI reporting configuration, which are measurement results based on the first reference signal resources of M ports and measurement results based on the second reference signal resources of N ports, respectively.

[0107] 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.

[0108] For example, the second reference signal resources of the N ports are part of the first reference signal resources of the M ports, and both are configured based on the first resources. The terminal device receives one CSI reporting configuration, and the first CSI reporting configuration is simultaneously associated with the first reference signal resources of the M ports and the second reference signal resources of the N ports, and the terminal device feeds back one CSI result based on the CSI reporting configuration. For example, the terminal device can determine whether the measurement result included in the CSI report is based on the first reference signal resources of the M ports or the second reference signal resources of the N ports based on the indication information of the DCI and / or a predefined rule.

[0109] 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.

[0110] For example, the first reference signal resource for M ports and the second reference signal resource for N ports are configured based on two independent resources. The terminal device receives one CSI reporting configuration, and the first CSI reporting configuration is simultaneously associated with the first reference signal resource for M ports and the second reference signal resource for N ports. The terminal device feeds back two CSI results based on the CSI reporting configuration, which are measurement results based on the first reference signal resource for M ports and measurement results based on the second reference signal resource for N ports, respectively.

[0111] The above explains how to report CSI, and the following explains how to check, trigger, or switch.

[0112] In some embodiments, the terminal device determines the first and second reference signal resources for M ports based on an RRC configuration, and determines that the CSI measurement resources are the first resource for M ports and the second resource for N ports. The terminal device can simultaneously measure two resources, which means that the terminal device measures resources corresponding to different port configurations of the same resource. The different port configurations correspond to different spatial domain element muting modes or spatial domain element configurations.

[0113] In some embodiments, the terminal device receives the fifth information and / or the sixth information, and determines, based on the fifth information and / or the sixth information, to perform channel state information (CSI) reporting using the first reference signal resource of the M port and / or the second reference signal resource of the N port.

[0114] For example, the fifth information may be carried by downlink control information (DCI) and / or a medium access control (MAC) control element (CE), the fifth information may be carried by UE-specific signaling or may be carried by group common signaling, which is used to simultaneously transmit information to multiple terminal devices, and the sixth information may be carried by radio resource control (RRC) signaling and / or a medium access control (MAC) control element (CE). The sixth information may be configured by UE-specific signaling, or may be configured by cell-specific or group-specific signaling.

[0115] Thus, the terminal device can determine, for example, based on the DCI, whether the CSI measurement resource is the first resource of port M, the second resource of port N, or the first resource of port M and the second resource of port N, or whether the terminal reports the first CSI, the second CSI, or the first CSI and the second CSI simultaneously. For example, after configuring the first reference signal resource and the second reference signal resource by RRC, the network device can further dynamically instruct the terminal device to report CSI by, for example, confirming, indicating, triggering, or switching by DCI, so that CSI reporting becomes more efficient and accurate.

[0116] In some embodiments, the fifth information is used to indicate at least one of the following: network status, terminal equipment performing channel state information (CSI) measurements, terminal equipment performing channel state information (CSI) measurements using the first reference signal resource of the M port, and terminal equipment performing channel state information (CSI) measurements using the second reference signal resource of the N port, CSI-RS resource configuration update / adjustment / switching, CSI reporting configuration update / adjustment / switching, CSI-RS port adjustment, CSI-RS port activation / deactivation indication, CSI-RS port enable indication, CSI measurement adjustment, indication regarding discontinuous reception, and indication regarding discontinuous transmission.

[0117] The fifth information indicating the channel state information report update / adjustment / switching can be used to indicate the number of channel information reports and / or specific channel state information after updating / adjusting / switching, and the specific channel state information is the first channel state information and / or the second state information.

[0118] In some embodiments, the sixth information is used to indicate at least one of the following: a timer / counter for the network condition, a discontinuous receive period setting for the network condition, and a discontinuous transmit period setting for the network condition.

[0119] In some embodiments, the network state is used to indicate at least one of the following: a first mode, a second mode, a switch of the first mode to the second mode, a switch of the second mode to the first mode, a time domain element adjustment, a spatial domain element adjustment, and an energy domain element adjustment.

[0120] For example, the first mode is at least one of the following: energy saving mode, power saving mode, sleep mode, abnormal mode, inactive mode, the mode after the network device adjusts the CSI-RS port, and a first configuration method for the CSI-RS port; and the second mode is at least one of the following: non-energy saving mode, non-power saving mode, non-sleep mode, normal mode, active mode, the mode before the network device adjusts the CSI-RS port, and a second configuration method for the CSI-RS port.

[0121] Also, for example, the spatial domain element is used to indicate at least one of the following: an antenna port, a logical port, a reference signal port, an antenna factor, an antenna element, and an antenna unit. The energy domain element is used to indicate at least one of the following: an energy per resource element of a Physical Downlink Shared Channel (PDSCH) and an energy per resource element of a Channel State Information Reference Signal.

[0122] The fifth information can be used in a scenario of dynamic antenna element adjustment in network energy saving technology, and the sixth information can be used in a scenario of semi-persistent or semi-static antenna element adjustment in network energy saving technology, in which the fifth information and / or the sixth information can be used to indicate / switch CSI, i.e., to indicate / switch antenna element muting mode / scheme.

[0123] For example, in a network energy-saving scenario, a base station configures a first CSI, a second CSI, a third CSI, and a fourth CSI, which are respectively associated with 32-port, 16-port, 8-port, and 4-port CSI-RSs, where 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, second CSI, third CSI, and fourth CSI correspond to different antenna element muting modes / settings / mechanisms, respectively. The antenna element muting may be replaced by port muting, antenna on / off switching, etc.

[0124] The terminal device can perform CSI measurements based on 32-port CSI-RS and report the first CSI, or the terminal device can simultaneously perform CSI measurements based on 32-port, 16-port, 8-port, and 4-port CSI-RS and report the first CSI, second CSI, third CSI, and fourth CSI.

[0125] The fifth information and / or sixth information is used for CSI switching. For example, in an initial state, a terminal reports CSI corresponding to CSI-RS of 32 ports, and the terminal device receives fifth information (DCI signaling 1), which instructs the terminal to report two CSIs, the second CSI and the third CSI, respectively, and the terminal device reports the second CSI and the third CSI. After a time has passed, the terminal receives fifth information (DCI signaling 2), which instructs the terminal device to report three CSIs, the second CSI, the third CSI, and the fourth CSI, respectively, and the terminal device reports the second CSI, the third CSI, and the fourth CSI.

[0126] Alternatively, under an initial state, the terminal reports CSI corresponding to the CSI-RS of port 32, and the terminal device obtains sixth information (timer expiration or restart), and reports the second CSI and third CSI based on a pre-defined rule or preset information. After a time has passed, the terminal obtains the sixth information (timer restart or expiration), and the terminal device reports the first CSI.

[0127] 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 may be included in different CSI reporting configurations (CSI-ReportConfig).

[0128] For example, the fifth information is carried by DCI signaling. When the first CSI, the second CSI, the third CSI, and the fourth CSI are included in different CSI reporting configurations, the fifth information is used to simultaneously activate / deactivate multiple different semi-persistent or aperiodic CSI reports, thereby saving DCI signaling overhead compared to the prior art. When the first CSI, the second CSI, the third CSI, and the fourth CSI are included in the same CSI reporting configuration, the fifth information is used to indicate the number and specific CSIs included in the CSI reporting configuration.

[0129] In some embodiments, the second reference signal resource of the N ports may be zero, i.e., the network device does not transmit CSI-RS. When the terminal device obtains the fifth information and / or the sixth information, the terminal device does not receive CSI-RS and does not perform CSI measurement and CSI reporting.

[0130] For example, when the terminal device receives the fifth information or obtains the sixth information (timer exceeded), the terminal device knows that the network device does not transmit the CSI-RS signal, and performs a skip process or a muting process so that the terminal device does not receive the CSI-RS signal and does not perform CSI measurement or CSI reporting.

[0131] In some embodiments, the fifth information may be carried by existing signaling, such as DCI signaling triggering PUSCH-based semi-persistent CSI reporting or aperiodic CSI reporting, or new signaling may be defined.

[0132] The above-described embodiments are merely illustrative of the present invention, and the present invention is not limited thereto. Furthermore, appropriate modifications can be made based on the above-described embodiments. For example, the above-described embodiments may be used individually, or a plurality of the above-described embodiments may be used in combination.

[0133] As can be seen from the above embodiments, a terminal device receives a channel state information (CSI) reporting configuration to configure reporting of first channel state information (CSI) and / or second channel state information (CSI), where the first channel state information (CSI) is associated with a first reference signal resource of M ports and the second channel state information (CSI) is associated with a second reference signal resource of N ports. This allows the terminal device to efficiently and accurately report CSI without additionally increasing the number of channel state information (CSI) reporting configurations in the case of resource adjustment (e.g., for the purpose of energy saving), thereby providing accurate channel information for scheduling by a network device.

[0157] As can be seen from the above embodiments, a terminal device receives a channel state information (CSI) reporting configuration to configure reporting of first channel state information (CSI) and / or second channel state information (CSI), where the first channel state information (CSI) is associated with a first reference signal resource of M ports and the second channel state information (CSI) is associated with a second reference signal resource of N ports.
