Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic architectural diagram of a communication system 1000 applied in an embodiment of the present application. As shown in Figure 1, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The radio access network 100 may include at least one radio access network device (110a and 110b in Figure 1), and may also include at least one terminal (120a-120j in Figure 1). The terminal is connected to the wireless access network equipment through wireless means, and the wireless access network equipment is connected to the core network through wireless or wired means. The core network equipment and the radio access network equipment can be independent and different physical devices, or the functions of the core network equipment and the logical functions of the radio access network equipment can be integrated on the same physical device, or they can be one physical device. It integrates the functions of some core network equipment and some functions of wireless access network equipment. Terminals and terminals and wireless access network equipment and wireless access network equipment can be connected to each other in a wired or wireless manner. Figure 1 is only a schematic diagram. The communication system may also include other network equipment, such as wireless relay equipment and wireless backhaul equipment, which are not shown in Figure 1 .

The CU here completes the functions of the base station's radio resource control protocol and packet data convergence protocol (PDCP), and can also complete the functions of the service data adaptation protocol (SDAP); DU completes the functions of the base station The functions of the wireless link control layer and medium access control (MAC) layer can also complete some or all of the physical layer functions. For specific descriptions of each of the above protocol layers, please refer to the Third Generation Partner Program (3rd generation partnership project, 3GPP) related technical specifications. The wireless access network equipment may be a macro base station (110a in Figure 1), a micro base station or an indoor station (110b in Figure 1), or a relay node or donor node. The embodiments of this application do not limit the specific technology and specific equipment form used by the wireless access network equipment. For convenience of description, the following description takes a base station as an example of a radio access network device.

The terminal can also be called terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things ( internet of things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver functions, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technology and specific equipment form used by the terminal.

The embodiments of this application do not limit the application scenarios of base stations and terminals.

The roles of the base station and the terminal may be relative. For example, the helicopter or drone 120i in Figure 1 may be configured as a mobile base station. For those terminals 120j that access the wireless access network 100 through 120i, the terminal 120i is Base station; but for base station 110a, 120i is a terminal, that is, communication between 110a and 120i is through a wireless air interface protocol. Of course, communication between 110a and 120i can also be carried out through an interface protocol between base stations. At this time, relative to 110a, 120i is also a base station. Therefore, both base stations and terminals can be collectively called communication devices, 110a and 110b in Figure 1 can be called communication devices with base station functions, and 120a-120j in Figure 1 can be called communication devices with terminal functions.

The technical solutions provided by the embodiments of this application can be applied to wireless communications between communication devices. Wireless communication between communication devices may include: wireless communication between network devices and terminals, wireless communication between network devices and network devices, and wireless communication between terminal devices. Among them, in the embodiments of this application, the term "wireless communication" can also be referred to as "communication", and the term "communication" can also be described as "data transmission", "information transmission" or "transmission".

It can be understood that in the embodiments of the present application, the physical uplink share channel (physical downlink share channel, PDSCH), the physical downlink control channel (physical downlink control channel, PDCCH) and the physical uplink share channel (physical uplink share channel, PUSCH) These are just examples of the downlink data channel, downlink control channel and uplink data channel respectively. In different systems and different scenarios, the data channel and the control channel may have different names. The embodiments of this application do not limit this. .

During the communication process, the base station and the terminal will obtain the channel state information (CSI) by measuring signals, and then send and receive data based on the obtained channel state information. The main idea of channel measurement and interference measurement in NR is to measure the channel or interference by sending a reference signal (RS) of a known sequence. In NR, the downlink channel is usually measured through the channel state information reference signal (CSI-reference signal, CSI-RS), and the uplink channel is measured through the channel sounding reference signal (sounding reference signal, SRS). Of course, for time division duplex (TDD) systems, the mutuality of uplink and downlink channels can also be used to obtain the channel status. This application is mainly aimed at downlink channel/interference measurement.

The downlink channel is generally measured through CSI-RS. The base station sends CSI-RS, and after receiving the CSI-RS, the UE measures the channel through the CSI-RS. There are two methods for interference measurement: one is for the UE to receive the CSI-RS sent by the base station for measurement. The CSI-RS used for interference measurement and the CSI-RS used for channel measurement can be the same or different; the other The UE receives the zero power CSI-RS (ZP-CSI-RS) indication. The zero power CSI-RS indicates that the base station does not send any content at the time and frequency position indicated by this reference signal, so that the UE is at this time and frequency position. What is received is interference and noise. Based on the received reference signal, the UE calculates the indicators that need to be measured, such as rank indicator (rank indicator), pre-coding matrix indicator (pre-coding matrix indicator, PMI), channel quality indicator (channel quantity indicator, CQI), and then reports it these contents. The set of reported indicators is called a CSI report. The base station receives the CSI report, obtains the channel status information when it sends downlink signals, and sends downlink signals to the terminal with reference to the CSI report.

In order to facilitate understanding of the solutions of the embodiments of the present application, relevant concepts are explained.

1. Channel status information report configuration (CSI-ReportConfig): Mainly used to configure parameters related to channel status reporting, such as reporting type, reported measurement indicators, etc. Among them, the reporting configuration identification (reportConfigId) is the identification (identity, Id) number of the CSI-ReportConfig, used to mark the CSI-ReportConfig; the channel measurement resources (resourcesForChannelMeasurement) are used to configure the channel state information-reference signal for channel measurement. (CSI-Reference Signal, CSI-RS) resources, which are associated to resource configuration through CSI-ResourceConfigId; interference measurement resources (CSI-IM-RessourcesForInterference), which configure CSI-RS resources for interference measurement, are associated to CSI-ResourceConfigId. Resource allocation.

Optionally, parameters related to CSI reporting may include CSI reporting type (reportConfigType), CSI reporting quantity (reportQuantity), etc. CSI reporting types may be divided into periodic (periodic), semi-static (semiPersistentOnPUCCH) or semiPersistentOnPUSCH) and aperiodic reporting; network equipment can be configured with different reporting amounts to allow terminal equipment to report different CSI, including CSI-RS resource indicator (CSI-RS resource indicator, CRI), rank indicator (rank indicator) , RI), Pre-coding Matrix Indicator (PMI), Channel Quality Indicator (Channel Quantity Indicator, CQI), etc.

2. Channel state information resource configuration (CSI-ResourceConfig): used to configure resource-related information for CSI measurement. It may include reporting resource identification (CSI-ResourceConfigId) and/or resource combination queue (CSI-RS-ResourceSetList), etc. The CSI-ResourceConfigId is used to mark the csi-ResourceConfig; the CSI-RS-ResourceSetList may include a resource set used for channel measurement and a resource set used for interference measurement.

3. Channel state information (CSI): When the signal passes through the wireless channel from the transmitter to the receiver, it may experience scattering, reflection, and energy attenuation with distance, resulting in fading. CSI is used to characterize wireless channels and can include CQI, PMI, CRI, synchronization signal and physical broadcast channel block (synchronization signal and physical broadcast channel block, SSB) resource indicator (SSB resource indicator, SSBRI), layer indicator (layer indicator) , LI), RI, at least one of L1-reference signal received power (RSRP) and L1-signal to interference plus noise ratio (SINR). CSI can be sent by the terminal device to the network device through the physical uplink control channel (PUCCH) or the physical uplink share channel (PUSCH).

4. CSI report: The CSI report is sent by the terminal to the base station and is used by the network device to learn the channel status when it sends downlink information to the terminal device. One CSI report is used to instruct the terminal device to feedback one CSI. Different CSIs can correspond to different frequency bands, different transmission assumptions or different reporting modes.

Generally speaking, a CSI report can be associated with one reference signal resource for channel measurement and one or more reference signal resources for interference measurement. A CSI report corresponds to a transmission resource, that is, the time-frequency resource used by the terminal device to send the CSI.

The CSI report in this application may also be called CSI reporting.

There are three types of CSI reporting, namely periodic CSI reporting, semi-persistent CSI reporting and aperiodic CSI reporting.

For periodic CSI reporting, the UE periodically sends channel state information. For example, the UE can send channel state information at intervals of T time units. The time units can be timeslots, milliseconds, subframes, etc.

For semi-persistent CSI reporting, the UE may periodically send channel state information within the first time period. For example, after the UE receives the activated MAC CE or PDCCH reported by the semi-persistent CSI, the UE sends channel state information at intervals of T time units. After that, after the UE receives the deactivated MAC CE or PDCCH reported by the semi-persistent CSI, the UE stops Send channel status information.

For aperiodic CSI reporting, the UE reports channel state information after receiving the activation signaling of aperiodic CSI reporting, and stops reporting channel state information after the reporting is completed.

5. Reference signal: It is a known signal provided by the transmitter to the receiver for channel estimation or channel detection. In embodiments of the present application, the reference signal can be used for channel measurement, interference measurement, etc., such as measuring parameters such as reference signal receiving quality (RSRQ), SINR, CQI, and/or PMI.

6. Reference signal resources: including at least one of time-frequency resources, antenna ports, power resources, scrambling codes and other resources of the reference signal. The network device may send a reference signal to the terminal device based on the reference signal resource, and accordingly, the terminal device may receive the reference signal based on the reference signal resource.

The reference signal involved in the embodiment of this application may include one or more of the following reference signals: channel state information reference signal (channel state information-reference signal, CSI-RS), SSB or sounding reference signal (sounding reference signal, SRS) . Correspondingly, the reference signal resources may include CSI-RS resources, SSB resources or SRS resources. In some cases, SSB can also refer to SSB resources.

7. Slot: A time domain unit for data scheduling. Under normal cyclic prefix, one slot has 14 symbols. Under extended cyclic prefix, one slot has 12 symbols. There are various time units in communication systems, which may include radio frames, subframes, slots, mini-slots or at least one orthogonal frequency division multiplexing (orthogonal frequency) division multiplexing (OFDM) uplink symbols and other time domain units. OFDM symbols may also be simply called symbols. The time length of a frame is 10ms, including 10 subframes, and the corresponding time length of each subframe is 1ms. A slot includes 12 symbols in the case of extended cyclic prefix and 14 symbols in the case of ordinary cyclic prefix. The time domain symbols here may be orthogonal frequency division multiplexing symbols. As shown in Figure 2, it is not An example of a relationship between different time units.

8. CSI processing unit (CPU): The terminal device needs to occupy certain storage resources to perform CSI calculations. In the 3GPP protocol, the number of CPUs is used to represent the resources required by the terminal to calculate CSI. The terminal device will report the number of CPUs it can support to the network device. For example, terminal device 1 notifies the base station that the maximum number of CPUs it supports is 10; terminal device 2 notifies the base station that the maximum number of CPUs it supports is 15. The maximum number of CPUs supported here refers to the number of CPUs supported simultaneously, which can be the number of CPUs supported by one carrier at the same time, or it can also be the number of CPUs supported by all carriers at the same time. For example, the terminal device only supports one CPU, which means that at the same time, the terminal device will only have one CPU for CSI processing.

The following describes the correlation between CSI configurations:

(b) in Figure 2 is a schematic diagram of an association between CSI configurations. CSI-ReportConfig includes a resourcesForChannelMeasurement configuration and a csi-IM-ResourcesForInterference configuration.

Among them, resourcesForChannelMeasurement corresponds to a CSI-ResourceConfig, and the CSI-ResourceConfig can be identified by CSI-resourceConfigId, that is, a CSI-ReportConfig includes a CSI-ResourceConfig. CSI-ResourceConfig also includes an indication of the measurement resource type (resourceType): {aperiodic, semiPersistent, periodic}.

A CSI-ResourceConfig includes a set of CSI-ResourceSet, which can be configured through nzp-CSI-RS-ResourceSetList. Currently, only one nzp-CSI-RS-ResourceSetList can be valid in a CSI-ResourceConfig.

An nzp-CSI-RS-ResourceSet includes a set of CSI-Resource, which can be configured through nzp-CSI-RS-Resource.

csi-IM-ResourcesForInterference is also configured through CSI-ResourceConfig, corresponding to a csi-IM-ResourceSetList.

In addition, for CSI-ReportConfig, it also includes an indication of the CSI report type reportConfigType: {periodic, semiPersistentOnPUCCH, semiPersistentOnPUSCH, aperiodic}.

For aperiodic CSI reporting (A-CSI), in addition to the above-mentioned CSI-Reportconfig association, an additional field is required: CSI-AperiodicTriggerState, which includes a set of CSI-Reportconfig, which can be configured through associatedReportConfigInfoList configuration.

The detailed functions of various configurations of CSI are as follows:

Among them, CSI-ReportConfig is mainly used for information related to CSI reporting. Here is a brief introduction to several related parameters:

reportConfigId: Id number of CSI-ReportConfig, used to identify the CSI-ReportConfig.

resourcesForChannelMeasurement: Configure CSI-RS resources for channel measurement, and associate them to resource configuration through CSI-ResourceConfigId.

CSI-IM-RessourcesForInterference: Configure CSI-RS resources for interference measurement, which are associated to resource configuration through CSI-ResourceConfigId. It should be understood that ZP-CSI-RS can also be used to describe resources for measuring interference.

nzp-CSI-RS-ResourcesForInterference: Configure NZP-CSI-RS resources for interference measurement, and associate them to the resource configuration through CSI-ResourceConfigId.

reportConfigType: The type of CSI reporting, which can be divided into periodic, semi-persistent and aperiodic reporting; the reporting period and the offset of the time slot (ReportPeriodicityAndOffset) are also configured. Periodic CSI reporting (P-CSI) is also configured with PUCCH reporting resources.

reportQuantity: The reported quantity (or reported indicator), you can choose to let the terminal device report different CSI information through different configurations, including CRI, RI, PMI, CQI, etc.

codebookConfig: Configure MIMO codebook-related information, such as codebook type (type1, type2), including the number of ports N1 and N2 in the horizontal and vertical directions, and the number of oversampling O1 and O2 in these two directions.

Currently, for CSI measurement, there are restrictions on the configuration of network devices and/or the execution of the measurement process by terminal devices. for example:

CSI-reportConfig: For each BWP, P/SP/A-CSI report can configure up to 4 CSI reports. This refers to the storage capacity of the terminal device. That is to say, the terminal device can store up to 4 CSI report configurations. For each CC, the total number of CSI reports is 8.

CSI-resourceConfig: P/SP-CSI can only include one resourceSet; A-CSI can include multiple resourceSets, but during each actual measurement process, the network device instructs the terminal device to use one of them;

CSI-resourceSet: At least one CSI resource in a resourceSet corresponds to the same number of ports, the same density, the same frequency domain RB, the same cdmtype, the same period, and the same spatial parameters. If a resourceSet includes 2 CSI resources, the maximum number of ports supported by each resource for measurement is 16; if a resourceSet includes 3 or more CSI resources, the maximum number of ports supported by each CSI resource for measurement is 8.

CSI-resource: The total number of ports including all CSI resources in each frequency band is 256.

It can be seen that the current CSI reporting capabilities and CSI measurement capabilities of terminal equipment are relatively limited. On the other hand, in CSI measurement, the communication environment may change, such as airspace parameters changing dynamically. The current correlation between CSI measurement and CSI reporting is changed through RRC signaling, which is usually on the order of hundreds of milliseconds and cannot meet the rapid changes in the communication environment. In other words, the CSI configuration cannot be changed in time to match the updated communication environment, such as new airspace parameters. This will lead to inaccurate CSI measurement results, further seriously affecting communication quality.

In response to the above problems, embodiments of the present application propose an information transmission method, which improves the measurement capabilities of the terminal equipment and improves the accuracy of CSI measurement by configuring multiple CSI reporting configurations for the terminal equipment. The following uses network equipment and terminal equipment as examples of communication parties to describe the solution of the embodiment of the present application. As shown in Figure X, the method may include the following steps:

Step 301: The network device sends first configuration information to the terminal device. The first configuration information includes M pieces of second configuration information. Correspondingly, the terminal device receives the first configuration information. Wherein, the M pieces of second configuration information are used to configure M pieces of CSI measurement resources.

In one possible situation, the M CSI measurement resources are configured independently. The independent configuration here can be understood as that the M CSI measurement resources correspond to M independent configuration fields. For example, the first configuration information is CSI reporting configuration, the second configuration information is CSI resource configuration (CSI-ResourceConfig), and the CSI reporting configuration includes M CSI resource configuration fields. Or it can be understood that a configuration field in the prior art includes a parameter configuration with M independent values. For example, the first configuration information is the CSI measurement resource, and the second configuration information is the power offset (offset) of the CSI-RS and the PDSCH, that is, one CSI measurement resource includes M different values of the above offset.

In another possible situation, the M CSI measurement resources are different, and M is an integer greater than 1.

For the above two situations, a possible implementation is that the M second configuration information corresponds to the M first parameters one-to-one, and the M first parameters correspond to the M measurement resources one-to-one. The first parameter can be It is at least one of the following: CSI-RS air domain information or RB or RB index of CSI-RS frequency domain in a CSI resource set.

The CSI-RS airspace information here can be understood as the number and/or pattern of CSI-RS ports, or the number and/or pattern of CSI-RS elements (element or antenna element), or a CSI -The number and/or patterns included in the RS port. The pattern here can be vertical or horizontal distribution.

Further, the above-mentioned first parameter may also include at least one of the following: CSI-RS period and starting offset, power offset of CSI-RS and PDSCH, and CSI-RS transmission power. In the existing technology, these parameters can already be configured independently for multiple parameters.

CSI-RS is the CSI reference signal. Optionally, the CSI reference signal can be configured through the NZP-CSI-RS-resource field. The M CSI measurement resources may be different, and the M first parameters may be different, and the following situations may occur.

Case A: Different first parameters include different parameter items.

Since the first parameter can be at least one of the above multiple example parameters, situation A can be divided into the following two situations:

Case (1): The first parameter includes one parameter item. In other words, the first parameter is one of the above-mentioned multiple example parameters. For example, the first parameter may be the power offset of CSI-RS and PDSCH, or the first parameter may be the RB or RB index in the CSI-RS frequency domain. , or the first parameter may be the CSI-RS period and starting offset, or the first parameter may be the number of CSI-RS ports, or the first parameter may be the CSI-RS transmit power. In this case, the M first parameters may be different (taking the value of M as 4 as an example): the first parameter #1 is the power offset of CSI-RS and PDSCH, and the first parameter #2 is the CSI-RS frequency domain RB index, the first parameter #3 is the number of CSI-RS ports, and the first parameter #4 is the CSI-RS transmit power.

Case (2): The first parameter may be multiple of the above multiple example parameters. In other words, the first parameter may be a combination of multiple example parameters described above. This can include two situations:

Case ①: Different first parameters include different numbers of parameter items. For example, first parameter #1 includes three parameters. For example, the first parameter may include the CSI-RS period, starting offset, and the number of CSI-RS ports. and CSI-RS transmit power; the first parameter #2 includes two parameters. For example, the first parameter may include the power offset of CSI-RS and PDSCH, and the RB index of the CSI-RS frequency domain.

Case ②: Different first parameters include the same number of parameter items but different parameter items. For example, the first parameter #1 and the first parameter #2 include two parameters respectively, but the first parameter #1 includes the CSI-RS port. quantity and CSI-RS transmit power, the first parameter #2 includes The number of CSI-RS ports and the RB index in the CSI-RS frequency domain.

Case B: Different first parameters include the same parameter items but different values.

It should be understood that it has been determined that different first parameters include the same parameter items: different first parameters include the same number of parameter items. For example, the first parameter #1 includes the number of CSI-RS ports and the CSI-RS transmit power, and the first parameter #2 also includes the number of CSI-RS ports and the CSI-RS transmit power.

This can also be divided into two situations:

Case ①: The number of parameter items included in different first parameters is all 1. Then different first parameters include the same parameter items but have different values, which can be understood as different first parameters having different values. For example, the first parameter #1 includes the number of CSI-RS ports, and the first parameter #2 includes the number of CSI-RS ports. However, the number of CSI-RS ports included in the first parameter #1 is 32, The value of the number of CSI-RS ports included in the first parameter #2 is 16.

Case ②: The number of parameter items included in different first parameters is greater than 1, then the parameter items included in different first parameters are the same but have different values. This can be understood as the value of at least one parameter item in the different first parameters. different. For example, the first parameter #1 includes the number of CSI-RS ports and the RB index in the CSI-RS frequency domain, and the first parameter #2 includes the number of CSI-RS ports and the RB index in the CSI-RS frequency domain, which is different. The parameter items included in the first parameter are the same, and the different values may be: the number of CSI-RS ports included in the first parameter #1 is 32, the RB index is 1, and the number of CSI-RS ports included in the first parameter #2 The quantity value is 16, and the RB index is 1. For another example, the first parameter #1 includes the number of CSI-RS ports and the RB index in the CSI-RS frequency domain, and the first parameter #2 includes the number of CSI-RS ports and the RB index in the CSI-RS frequency domain, then Different first parameters include the same parameter items, and different values may be: the number of CSI-RS ports included in the first parameter #1 is 32, the RB index is 1, and the CSI-RS included in the first parameter #2 The number of ports is 16, and the RB index is 2.

It should be understood that the above numbers are only examples and not limitations.

Corresponding to different first parameters, the M CSI measurement resources being different may mean that at least two of the M CSI measurement resources are different. It can be understood that the M CSI measurement resources may also be different from each other. Specifically, one way of determining whether two CSI measurement resources are the same may be to determine whether the first parameters corresponding to the two CSI measurement resources are the same. Further, the method of determining whether two first parameters are the same can refer to the previous description. For example, the two first parameters that meet the above situation A or situation B are two different first parameters. I won’t go into details here. It should be understood that the M CSI measurement resources are configured through M pieces of second configuration information. The M CSI measurement resources are different, which can also be understood as the M pieces of second configuration information are different.

The above explains what the first parameter is different, how to determine that the M CSI measurement resources are different, and what the M second configuration information is different. The following explains in detail the association between the first configuration information and the second configuration information.

In one possible implementation, the first configuration information may include M pieces of second configuration information. For example, the first configuration information is an RRC field, the second configuration information is also an RRC field, and M pieces of second configuration information are carried in the first configuration information.

Several examples of first configuration information and second configuration information are given below:

Example 1: The first configuration information is CSI report configuration (CSI-reportConfig) information, and the second configuration information is CSI resource configuration (CSI-resourceConfig) information. One possible configuration is as follows:

Among them, the first configuration information is CSI-ReportConfig, and the M pieces of second configuration information are resourcesListForChannelMeasurement. The M pieces of second configuration information may be distinguished by identifiers of the configuration information, and the identifier of the configuration information may be CSI-ResourceConfigId. That is to say, the M pieces of second configuration information may be distinguished by identifiers 1, 2, 3...M. Alternatively, it may also be other identifiers that can be used to distinguish different configuration information, which is not limited in the embodiment of the present application. The terminal device can determine the corresponding second configuration information through the M different identifiers.

It can be understood that each of the M CSI-resourceConfigs can include a first parameter, and the parameter items included in the first parameter can have many situations. For details, please refer to the previous description, and will not be repeated here. . In other words, all NZP-CSI-RS-resources associated with this CSI-resourceConfig are configured with this first parameter.

For example, in order to measure the CSI under different port shutdown conditions, the network device can configure two CSI-resourceConfig. Among them, the shutdown situation of the port is explained by taking the shutdown pattern (pattern) as an example. For example, the shutdown situation is: from port 32 to port 16, then the NZP-CSI-RS-resource included in one CSI-resourceConfig is all 32-port, and the NZP-CSI-RS-resource included in another CSI-resourceConfig is RS-resources are all 16 ports.

Among them, the shutdown pattern can be a pattern used to indicate the port switching status or the number of ports. For example, the shutdown pattern can be a bitmap. Different bit positions correspond to different ports, and the value of the bit at each bit position is used to Indicates whether the port's status is on or off. For example, bit position 1 corresponds to port 1, bit position 2 corresponds to port 2, the bit position 1 has a value of 1, indicating that the status of port 1 is on, and the bit position 2 has a value of 0, indicating that The status of port 2 is off. It should be understood that the above-mentioned correspondence between the bit value and the port status is only an example and not a limitation.

For another example, in order to measure CSI under different PDSCH powers (taking 0dB and -3dB as examples), the network device can configure two CSI-resourceConfig for the terminal device. One CSI-resourceConfig includes the NZP-CSI-RS-resource. The value of the poweroffset field is 0dB, and the value of the poweroffset field of NZP-CSI-RS-resource included in another CSI-resourceConfig is -3dB.

For another example, in order to measure partial bandwidth CSI (taking 24RB and 48RB as an example), the network device can configure two CSI-resourceConfig for the terminal device. The NZP-CSI-RS-resource included in one CSI-resourceConfig all occupies 48RB. The NZP-CSI-RS-resource included in another CSI-resourceConfig all occupies 24RB.

For another example, in order to flexibly adjust the measurement period (take 4slot&slotoffset=0, 8slot&slotoffset=2 as an example), the network device can configure two CSI-resourceConfig for the terminal device. The NZP-CSI-RS-resource included in one CSI-resourceConfig is 4slot&slotoffset=0, and the NZP-CSI-RS-resource included in another CSI-resourceConfig is 8slot&slotoffset=2.

It should be understood that the numerical values in the above examples are only examples and not limiting, and the above examples are not intended to be limiting.

In this example, the network device configures multiple sets of CSI-RS parameters for the terminal device by configuring multiple CSI-resourceConfig, so that measurement results of multiple CSI-RS parameters can be obtained. Furthermore, multiple sets of measurement configurations can be applied to measurement environments with dynamically changing parameters, and CSI measurement can adapt to different measurement environments in a timely manner through different measurement parameters, improving measurement accuracy.

Example 2: The first configuration information is CSI resource configuration information (CSI-resourceConfig), and the second configuration information is CSI resource set configuration information (CSI-resourceSet). One possible configuration method: a CSI-reportConfig includes a resourceConfig, and M resourceSets are configured in this CSI-resourceConfig. The first parameters included in these M resourceSets are different. It can be understood that each resourceSet can include multiple resources. The first parameters corresponding to the multiple resources in each resourceSet are the same, and different resourceSets include different first parameters. There can be many situations where the first parameter is different. For details, please refer to the previous description and will not be repeated here.

For example, in order to measure CSI under different shutdown patterns (taking port 64 and port 32 as an example), the network device can configure two CSI-resourceSets for the terminal device. One CSI-resourceSet includes the NZP-CSI-RS-resource They are all 64ports, and the NZP-CSI-RS-resource included in another CSI-resourceSet are all 32ports.

For another example, in order to measure CSI under different PDSCH powers (taking 0dB and -3dB as examples), the network device can configure two CSI-resourceSets for the terminal device. One CSI-resourceSet includes the NZP-CSI-RS-resource. The value of the poweroffset field is 0dB, and the value of the poweroffset field of NZP-CSI-RS-resource included in another CSI-resourceSet is -3dB.

For another example, in order to measure partial bandwidth CSI (taking 24RB and 48RB as an example), the network device can configure two CSI-resourceSets for the terminal device. The NZP-CSI-RS-resource included in one CSI-resourceSet all occupies 48RB. The NZP-CSI-RS-resource included in another CSI-resourceSet occupies 24RB.

For another example, in order to flexibly adjust the measurement period (take 4slot&slotoffset=0, 8slot&slotoffset=2 as an example), the network device can configure two CSI-resourceSets for the terminal device. The NZP-CSI-RS-resources included in one CSI-resourceSet are all 4slot&slotoffset=0, and the NZP-CSI-RS-resource included in another CSI-resourceSet is 8slot&slotoffset=2.

Example 3: The first configuration information is CSI resource set configuration information (CSI-resourceSet), and the second configuration information is CSI resource information (CSI resource). One possible configuration method: include a CSI-resourceConfig in a CSI-reportConfig, in which M CSI resources are configured in a specified CSI-resourceSet, and the first parameters included in these M CSI resources are different. The so-called designated CSI-resourceSet may be predefined or preconfigured, or the network device may indicate the identifier of the CSI-resourceSet to the terminal device, such as CSI-resourceSetID. Or, the network device does not need instructions. When the terminal device After receiving the CSI-resourceConfig, the device determines that M CSI resources are configured in one of the CSI-resourceSets, and then learns that the CSI-resourceSet is the specified one. There may be many situations in which the above-mentioned first parameter is different. For details, please refer to the previous description and will not be repeated here.

For example, in order to measure CSI under different shutdown patterns (taking port 64 and port 32 as an example), the network device can configure two CSI-resources for the terminal device, such as NZP-CSI-RS-resource, and one NZP-CSI- RS-resource is port 64, and the other NZP-CSI-RS-resource is port 32.

For another example, in order to measure CSI under different PDSCH powers (taking 0dB and -3dB as an example), the network device can configure two CSI-resources for the terminal device, such as NZP-CSI-RS-resource, and one NZP-CSI- The value of the poweroffset field of RS-resource is 0dB, and the value of the poweroffset field of another NZP-CSI-RS-resource is -3dB.

For another example, in order to measure partial bandwidth CSI (take 24RB and 48RB as an example), the network device can configure two CSI-resources for the terminal device, such as NZP-CSI-RS-resource. One NZP-CSI-RS-resource occupies 48RB. , another NZP-CSI-RS-resource occupies 24RB.

For another example, in order to flexibly adjust the measurement period (take 4slot&slotoffset=0, 8slot&slotoffset=2 as an example), the network device can configure two CSI-resources for the terminal device, such as NZP-CSI-RS-resource, and one NZP-CSI-RS- The resource is 4slot&slotoffset=0, and the other NZP-CSI-RS-resource is 8slot&slotoffset=2.

Optionally, the network device may also send indication information to the terminal device, where the indication information is used to indicate whether the network device has configured a single set or multiple sets of CSI measurement configurations for the terminal device.

In one example, the network device may send first indication information to the terminal device, where the first indication information is used to indicate that the number of the second configuration information included in the first configuration information is greater than 1. That is to say, the network device configures multiple sets of CSI measurement configurations to the terminal device, or in other words, the network device configures multiple sets of CSI reporting configuration information to the terminal device.

A configuration example of the first indication information is as follows:

Among them, MultiReport is used to represent that the CSI-ReportConfig includes multiple sets of CSI configurations. The multiple sets of CSI configurations here can be the configurations of the multiple sets of measurement resources mentioned above, or are used to represent (or indicate) the need to report multiple sets of CSI configurations. CSI-report. In other words, if the MultiReport field is configured in the CSI-reportConfig, it means that the CSI-reportConfig includes multiple different first parameter configurations. If the multiReport field is not configured, it means that the CSI-reportConfig includes a first parameter.

It should be understood that the first indication information may be switch-type information. For example, the content and form of the first indication information are not limited, and its function is that the appearance (or existence) of the first indication information is used to indicate that the CSI-reportConfig includes a variety of different first parameter configurations. An indication information does not appear (that is, does not exist) to indicate that the CSI-reportConfig includes a first parameter, and vice versa.

In another example, the network device may implicitly indicate to the terminal device that multiple sets of CSI measurement configurations are configured, or the network device may implicitly indicate to the terminal device that multiple sets of CSI reporting configuration information are configured. For example, the CSI reporting configuration includes multiple CSI resource configurations, which means that the CSI reporting configuration is the multiple sets of CSI measurement configurations, or multiple sets of CSI reporting configuration information.

In another example, the network device may also send second indication information to the terminal device. The first configuration information is carried in the second indication information. The second indication information also includes third configuration information. The third configuration information includes a first parameter. , the index numbers of the first configuration information and the third configuration information are different. Wherein, the third configuration information including a first parameter may be understood to mean that the third configuration information includes a first parameter, or the third configuration information includes a first parameter. In other words, the network device configures different options for the terminal device, including multiple sets of CSI measurement configurations and a single set of CSI measurement configurations.

A configuration example of the second indication information is as follows:

The second indication information is CSI-MeasConfig. The second configuration information and the third configuration information are respectively configured by two different RRC fields. The M pieces of second configuration information are csi-ReportConfigToAddModListforMultiCSI, and the third configuration information is csi-ReportConfigToAddModList. The index number of the second configuration information is different from the index number of the third configuration information, and the terminal device can be distinguished by the different index numbers.

Optionally, when the network device configures multiple CSI measurement configurations (which can also be understood as multiple second configuration information, or multiple first parameters) for the terminal device, the network device also needs to expand the codebook configuration for the terminal device. The following takes the number of ports whose first parameter is the CSI-RS as an example for detailed explanation.

In order to configure or indicate port patterns corresponding to different logical port numbers, the configuration information (codebookConfig) for reporting MIMO codebooks in CSI-reportConfig needs to be expanded. It should be understood that the codebook configuration information is used to configure the codebook, and the codebook can be used to indicate the CSI-RS port. For example, the codebook may be used to indicate the number of CSI-RS ports. For example, the codebook may be used to indicate that the number of ports is 16. The codebook can also be used to indicate the distribution of CSI-RS ports (or the location of the ports, or the arrangement of the ports, etc.). For example, the codebook is used to indicate that the port distribution is 2*8 (that is, two rows and eight columns). Or 4*4 (that is, four rows and four columns), which is not limited in the embodiment of the present application.

One possible configuration method is to configure a set of codebookconfigs. This set of codebookConfig corresponds one-to-one to the M pieces of second configuration information (it can also be understood as a one-to-one correspondence to the CSI resources included in the configuration of the M pieces of second configuration information). . Possible configuration methods are as follows:

The codebookConfigList includes M CodebookConfigs, and the M CodebookConfigs can be distinguished by different identifiers, and the different identifiers can correspond one-to-one to the identifiers of the M pieces of second configuration information.

It should be understood that the above set of codebookconfigs can also be understood as a collection of codebookconfigs, or a list of codebookconfigs, or as a concept or noun with the same function as the above group, collection or list, or the above group does not exist. The concepts of , collection or list, as long as they include the configuration of multiple codebookconfigs, should be within the scope of protection of this application.

Another possible configuration method is to automatically match MIMO codebook parameters for different logical port patterns according to predefined rules. For example, you can predefine ports to be turned off from 64ports to 32ports. For example, the predefined rule is to turn off half the number of ports in the vertical direction, or turn off half the number of ports in the horizontal direction. Or, change the port-to-element mapping driver mode, so that the network device only needs to configure the codebook configuration of the 64-port port, and the terminal device can calculate the codebook corresponding to the 32-port port based on the above-mentioned predefined shutdown method.

Optionally, when the first parameter is CSI airspace information (number of bursts), the network device can configure M second configuration information. The M second configuration information is configured independently, and the M second configuration information is the same as the M second configuration information. Each codebook configuration has a one-to-one correspondence. The M codebook configurations may be included in the M second configuration information, or may be configured separately.

Optionally, when the network device configures multiple CSI measurement configurations for the terminal device (which can also be understood as multiple second configuration information, or multiple first parameters), the network device also needs to expand CSI interference measurement for the terminal device. . The following takes the number of ports whose first parameter is the CSI-RS as an example for detailed explanation.

When the first parameter is the number of logical ports of the CSI-RS, multiple sets of CSI measurement configurations need to match multiple sets of interference measurements. One way to configure multiple sets of interference measurements is to use NZP-CSI-RS resource to measure interference. At this time, it is necessary to configure M measurement resources (such as measurement signals) with different parameters included in the M second configuration information accordingly. M interfering measurement signals. Taking Example 1 above as an example, a possible configuration is as follows:

Among them, nzp-CSI-RS-ResourcesForInterference is the configuration information of the interference measurement resources, and the multiple interference measurement resources can be distinguished through different identification information. For example, the identification information can be CSI-ResourceConfigId. The identification information of the multiple interference measurement resources may be in one-to-one correspondence with the identification information of the multiple CSI measurement resources.

Another method to configure multiple sets of interference measurements is: for measuring interference using ZP-CSI-RS resource, M measurement resources (such as measurement signals) with different first parameters can jointly use the same interference measurement resource configuration. It is possible One allocation rule is that each measurement signal uses one RE that interferes with the measurement signal. One possible configuration is as follows:

Among them, csi-IM-ResourcesListForInterference is used to indicate the configuration of the above interference measurement resource.

Step 302: The terminal device sends N CSIs to the network device, and correspondingly, the network device receives the N CSIs.

Optionally, the terminal device reports N CSI based on N CSI measurement resources among the M CSI measurement resources, where N is a positive integer less than or equal to M. Different values of N can be divided into two categories: N is less than M, which can be understood as the terminal device reporting part of the measurement results corresponding to M CSI measurement resources to the network device; N equals M, which can be understood as the terminal device reporting to the network device All measurement results corresponding to M CSI measurement resources. In other words, for a CSI-reportConfig that includes M different configurations of measurement resources, such as measurement signals, CSI can be fed back for all M measurement signals, or part of the measurement signals can be fed back based on requirements or indication information. CSI, thereby reducing the computing power requirements of multiple sets of CSI.

The following details the different ways in which terminal devices report CSI:

Method 1: The terminal device reports the CSI corresponding to M measurement signals with different first parameters by default.

Specifically, for P-CSI reporting, as long as the RRC is configured with measurement configurations, all measurement configurations will take effect. That is to say, the terminal device performs periodic measurements and reports M (all) CSIs to the network device. For SP-CSI reporting, the terminal device can report all M CSIs by default.

Method 2: Predefine reporting rules. The reporting rules are: reporting the CSI of M measurement signals.

The predefined reporting rules may be predefined by the protocol, configured by RRC signaling, or may be instructed by the network device to the terminal device, which is not limited in the embodiments of this application.

In the above methods 1 and 2, the terminal device needs to report all measurement results. Possible reporting methods are:

Reporting method (a): The CSI of the M measurement signals can be jointly reported in one PUCCH or PUSCH. Specifically, the reporting resources can be configured through CSI-reportConfig, or indicated by the DCI that schedules PUSCH. Optionally, a compression method may be adopted during reporting. For example, when the first parameter is the CSIRS transmission power or the power offset of CSIRS and PDSCH, the M reported amounts may only include one PMI and M RI/CQIs.

Reporting method (b): The CSI of M measurement signals can be reported in multiple PUCCHs or PUSCHs according to predefined rules.

One possible way is to report M1 CSI in the first time unit and M2 CSI in the second time unit. The M1 CSI and the M2 CSIs to form the M CSIs. It should be understood that M1 CSI and M2 CSI may or may not overlap, but the complete set composed of M1 CSI and M2 CSI is the M CSI. In other words, different reporting resources or reporting periods can be configured for the M measurement signals, that is, the CSI of the M measurement signals is reported in time division, and the CSI of part of the measurement signals is reported in different reporting resources or reporting periods. For example, M measurement signals can be divided into Z groups, each group corresponding to a reporting resource. These Z reporting resources can be predefined, configured in CSI-reportConfig, or indicated by the network device to the terminal device through DCI. Which measurement signals correspond to each of the Z reporting resources may be predetermined by RRC or indicated by DCI. The DCI indication here can also be understood as a DCI with activation function. Specifically, the grouping method can be predefined through RRC, and the DCI is used to activate or indicate that the measurement configuration included in one of the groups takes effect.

Another possible way is that the terminal device can report CSI to the network device sequentially in a predefined order or the order of a predefined measurement signal set, that is, polling reporting. For example, M measurement signals can be divided into Y groups, and there is only one reported resource. The reported resource can be the PUCCH-resource configured in CSI-reportConfig, or the PUSCH resource indicated by DCI. Since the reporting resource is a periodic resource, a possible reporting method is to report the CSI of the first group of measurement signals on one reporting resource, report the CSI of the Yth group of measurement signals on the Yth resource, and report the CSI of the Yth group of measurement signals on the Y+1th resource. On each resource, the CSI of the first group of measurement signals is reported, and so on until the terminal device receives a new reporting instruction or stops reporting instructions.

Method 3: Report the CSI of part of the measurement signals according to the instructions of dynamic signaling.

For example, the network device may send indication information A to the terminal device. The indication information A is used to instruct to report channel measurement results corresponding to N pieces of second configuration information among the M pieces of second configuration information, where N is a positive number greater than 1 and less than M. integer. Optionally, the indication information A may be DCI, group DCI, MAC CE or group MAC CE.

The indication methods of the indication information A include the following:

Method 1: The indication information A is used to indicate the index of the measurement signal set. Specifically, the network device can be configured through RRC signaling, or the reporting set of measurement signals can be predefined. Taking a CSI-resourceSet including M CSI resources as an example, RRC signaling configures Z sets, and the M CSI resources belong to One or more of Z sets. The network device indicates that one of the Z sets takes effect through the indication information A. For the measurement signals included in this set, the terminal device needs to perform CSI measurement and reporting, and other sets do not report. It should be understood that the CSI resources included in the Z sets may overlap. For example, set 1 includes CSI resource1 and CSI resource2, and set 2 includes CSI resource1 and CSI resource3. Or, the CSI resources included in the Z sets have no overlap. Taking the value of M as 4 as an example, set 1 includes CSI resource1 and CSI resource2, and set 2 includes CSI resource3 and CSI resource 4. The embodiments of the present application do not limit this. Further, the Z sets can be distinguished by identification information, for example, by set indexes. For example, assuming the Z value is 3, the three sets correspond to indexes 1, 2, and 3 respectively. When the indication information A indicates index 3, the terminal device measures the CSI measurement signals in set 3 and reports the CSI corresponding to all measurement signals in set 3. For the measurement signals included in other sets, such as set 1 and set 2, the terminal device may or may not measure, but there is no need to report CSI.

Method 2: The indication information A is used to indicate the measurement signals corresponding to the N pieces of second configuration information.

It can also be understood that the indication information A is used to activate N pieces of second configuration information among the M pieces of second configuration information.

One possible way is that the indication information A is a bit pattern (bitmap). M bit positions in the bit pattern correspond to M pieces of second configuration information one-to-one. The bit value at each bit position can be used to indicate whether Report the measurement resources corresponding to the second configuration information, such as the CSI corresponding to the measurement signal. For example, assuming that the value of M is 3, the bit pattern includes three bits, namely bit 1, bit 2, and bit 3. These three bits correspond to measurement signal 1, measurement signal 2, and measurement signal 3 respectively. Bit The value of bit 1 is 1, the value of bit 2 is 0, and the value of bit 3 is 1, which means that the terminal device needs to measure and report the measurement result CSI of measurement signal 1 and measurement signal 3. The terminal device may or may not measure measurement signal 2, but does not need to report the CSI corresponding to measurement signal 2. It should be understood that the above values and the correspondence between the bit values and whether CSI needs to be reported are only examples and not limitations.

In another possible way, the indication information A may be used to indicate the index numbers corresponding to the N pieces of second configuration information. For example, assuming that the value of M is 3, and the index numbers corresponding to the three second configuration information are 1, 2, and 3 respectively, the indication information A can be used to indicate the index numbers 1 and 2, and the terminal device can according to the The indication information A determines that the CSI of the measurement signal corresponding to the second configuration information 1 and the second configuration information 2 needs to be measured and reported.

In the above method 1 and method 2, the indication information A may be DCI signaling or MAC CE signaling; it may be unicast signaling or multicast signaling.

One possible reporting method is to report N1 CSIs in the first time unit and N2 CSIs in the second time unit. The N1 CSI and the N2 CSI constitute the N CSI. It should be understood that N1 CSI and N2 CSI may or may not overlap, but the complete set composed of N1 CSI and N2 CSI is the N CSI. In other words, different reporting resources or reporting periods can be configured for N measurement signals, that is, time-division reporting is performed for the CSI of the N measurement signals, and the CSI of part of the measurement signals is reported in different reporting resources or reporting periods.

The indication information A may be sent by the network device to the terminal device alone. For example, optionally, the indication information A may be scrambled by a UE-specific RNTI.

Alternatively, the indication information A is group common signaling. Alternatively, the indication information A can be scrambled through G-RNTI, and the indication information A can be received by a group of UEs at the same time. For the design of group common signaling, one way is that in the signaling, each UE corresponds to X bits. For a group of Y UEs, the group common signaling includes a total of X*Y bits. Bit. Another way is that all UEs share X bits in this group common signaling, and each UE performs the above method based on the X bits in this group common signaling.

For example, for SP-CSI, the bits of the above indication information A indicate N of the M CSI reference signals (which may indicate indexes, or a predefined index set), which can be understood as activating the corresponding M CSI reference signals. N number of measurement resource configurations, or N number of reporting configurations associated with M CSI reference signals. That is, the terminal device finds the activated CSI-RS in the configured SP CSI-RS set, or finds the activated CSI reporting configuration in the configured SP CSI reporting configuration. The terminal device reports the CSI report corresponding to the activated CSI measurement resource. Optionally, the reported information of the SP CSI is carried on the PUCCH.

Method 3: Instruction information A is used to indicate the first threshold.

It should be understood that the value of the first threshold may be predefined or preconfigured, which is not limited in the embodiment of the present application. The terminal device may determine based on the first threshold and report CSI that is less than or equal to the first threshold. Alternatively, the terminal device may determine based on the first threshold and report CSI that is greater than or equal to the first threshold.

Alternatively, taking the first parameter as the number of ports as an example, the first threshold may be the number of ports. The terminal device may determine based on the first threshold and report the CSI corresponding to the measurement signal whose number of ports is less than or equal to the first threshold. Alternatively, the terminal device may determine based on the first threshold and report the CSI corresponding to the measurement signal that is greater than or equal to the first threshold. This is not limited in the embodiment of the present application.

In this embodiment, the network device configures multiple sets of CSI measurement configurations for the terminal device. When the measurement environment changes, for example, when the number of antenna ports changes, the terminal device can promptly call the measurement configuration corresponding to the new parameters to quickly and flexibly match The dynamically changing measurement environment improves measurement accuracy and can further improve the quality of communication based on measurement results.

This application also proposes an embodiment that provides another information transmission method, which can also provide multiple sets of measurement configurations. The measurement method is shown in Figure 4 and may include the following steps:

Step 401: The network device sends first information to the terminal device, where the first information includes configuration information reported by Q CSIs. Correspondingly, the terminal device receives the first information.

Optionally, Q is a positive integer greater than P, P is the maximum number of CSI reports per BWP supported by the terminal device, and P is a positive integer. The maximum number of CSI reports per BWP supported by the terminal device can also be understood as the terminal device's per-BWP CSI reporting capability, or it can also be understood as the terminal device's ability to store CSI reporting configurations per BWP. Specifically, the storage and processing of CSI configuration by the terminal device will occupy hardware or software resources. Therefore, there is an upper limit on the storage and processing capabilities of the terminal device. Q here is greater than P, that is, the network device configures a reported configuration for the terminal device that exceeds the storage capacity or processing capacity of the terminal device.

Optionally, Q CSI reports include quantity, the sum of the maximum number of semi-persistent CSI reports per BWP and the maximum number of aperiodic CSI reports.

It should be understood that Q CSI reports may also include X periodic CSI reports and Y semi-persistent CSI reports. Alternatively, the Q reports may also include X periodic CSI reports and Z aperiodic CSI reports. Alternatively, the Q reports may also include Y semi-persistent CSI reports and Z aperiodic CSI reports. In this way, X, Y, and Z are respectively integers less than or equal to Q. When Q CSI reports include less than three types of CSI reports, X, Y, and Z can take 0.

Optionally, Q CSI reports are Q periodic CSI reports, Q is a positive integer greater than P, and P is the maximum number of periodic CSI reports supported by each BWP terminal device.

Optionally, Q CSI reports are Q semi-persistent CSI reports, Q is a positive integer greater than P, and P is the maximum number of semi-persistent CSI reports supported by each BWP terminal device.

Optionally, Q CSI reports are Q aperiodic CSI reports, Q is a positive integer greater than P, and P is the number of times each BWP terminal device supports The maximum number of aperiodic CSI reports maintained.

The configuration information reported by the Q pieces of CSI includes different first parameters, and the first parameter is at least one of the following: the number of CSI-RS ports, CSI-RS transmit power, power offset of CSI-RS and PDSCH, RB or RB index, CSI-RS measurement period or starting offset in the CSI-RS frequency domain. Specifically, for the so-called first parameters to be different, please refer to the description in step 301, which will not be described again here.

For example, the first information is RRC signaling. For the reporting and measurement of P-CSI or SP-CSI or A-CSI, the first information includes Q CSI-reportConfig, and each CSI in the Q CSI-reportConfig -reportConfig only includes one first parameter. For example, the first parameter included in CSI-reportConfig#A is the number of CSI-RS ports, and the first parameter included in CSI-reportConfig#B is the CSI-RS transmit power. CSI-reportConfig The first parameter included in #C is the power offset of CSI-RS and PDSCH, and the RB index of CSI-RS frequency domain. Optionally, Q is greater than P (P is the capability of the terminal device, that is, the maximum supported number of storage CSI reporting configurations).

For another example, for SP-CSI and A-CSI, the first information configures a CSI-reportConfig, and the CSI-reportConfig includes Q CSI-resourceConfig. Each of the Q CSI-resourceConfigs includes only one kind of first parameter. Optionally, Q is greater than P, and P can be understood as the number of CSI-resourceConfig corresponding to one CSI reporting configuration. For example, one CSI reporting configuration corresponds to one CSI resource configuration.

For another example, for SP-CSI and A-CSI, the first information configures a CSI-resourceConfig, and the CSI-resourceConfig includes Q NZP-CSI-RS resources. Each of the Q NZP-CSI-RS resources includes only one first parameter. Optionally, Q is greater than P, and P can be understood as the total number of ports of the NZP-CSI-RS resource corresponding to one CSI reporting configuration. For example, one CSI reporting configuration corresponds to the total number of 256 resource ports.

For another example, for SP-CSI, the first information configuration triggerstate includes Q CSI-reportconfigs, and each of the Q CSI-reportconfigs includes only one first parameter. Optionally, Q is greater than P (P is the capability of the terminal device, for example, the number of CSI reporting configurations supported in one triggerstate is 16).

For another example, for A-CSI, the first information is RRC signaling, and Q triggerstates can be configured, each triggerstate includes a set of CSI-reportconfig. Optionally, Q is greater than P (P is the capability of the terminal device, for example, the number of supported triggerstates P is 128).

For another example, for A-CSI, the first information configuration triggerstate includes Q CSI-reportconfigs. Optionally, Q is greater than P (P is the capability of the terminal device, for example, the number P of CSI reporting configurations supported in one triggerstate is 16).

One possible implementation is that the Q pieces of CSI reported configuration information configured by the network device for the terminal device belong to at least two BWPs, and the number of CSI reported configuration information included in each of the at least two BWPs is less than or equal to P, That is to say, the amount of configuration information reported by CSI included in each BWP cannot exceed the maximum amount of configuration information reported by CSI supported by the terminal device. The configuration information reported by Q CSIs belongs to at least two BWPs. It can also be understood that the configuration of CSI-Report is BWP level (also called per BWP). For example, the network device configures two CSI-reportConfig under BWP for the terminal device. These two sets of CSI-reportConfig are managed uniformly. For example, the index numbers can be uniformly numbered, totaling Q. It should be understood that, taking two BWPs as an example, Q is less than or equal to 2*q, and q is the maximum number of configuration information reported by CSI that the terminal device can support on each BWP.

For example, the configuration information reported by the Q pieces of CSI is Q periodic (periodic) CSI reporting configurations; or the configuration information reported by the Q pieces of CSI is Q semi-static (semiPersistent) CSI reporting configurations; or, the reported configuration information of the Q pieces of CSI The configuration information is Q semi-static CSI resource configurations; or the configuration information reported by Q CSIs is Q semi-static CSI measurement resources; or the configuration information reported by Q CSIs is Q aperiodic CSI trigger states (TriggerState); Alternatively, the configuration information reported by Q CSIs is Q aperiodic CSI reported configurations; or the configuration information reported by Q CSIs is Q aperiodic CSI resource configurations; or the configuration information reported by Q CSIs is Q aperiodic CSI resource configurations. CSI measurement resources.

Step 402: The terminal device sends R CSI reports to the network device, where R is a positive integer less than or equal to Q. Correspondingly, the network device receives the R CSI reports.

Optionally, the R CSI reports correspond to the R CSI reported configuration information one-to-one, and the R CSI reported configuration information belongs to the Q reported configuration information.

Optionally, R is a positive integer less than or equal to P. In other words, the number of CSIs reported by the terminal device is within the capability of the terminal device. For example, if the terminal device supports reporting a maximum of 4 CSIs, then the terminal device can report 4 CSIs. CSI, or 3 CSIs, or 2 CSIs, or 1 CSI, or no CSI is reported, which is not limited in the embodiment of the present application. It can be understood that when the CSI reported by the network device configured for the terminal device exceeds the capability of the terminal device, the terminal device needs to further determine which CSI to report.

Optionally, R is a positive integer less than or equal to P, which is the sum of the maximum number of periodic CSI reports, the maximum number of semi-persistent CSI reports, and the maximum number of aperiodic CSI reports supported by each BWP terminal device. In other words, the number of CSI reported by the terminal device Within the capabilities of the terminal device.

Optionally, R is a positive integer less than or equal to P, the R CSI reports are R periodic CSI reports, and P is the maximum number of periodic CSI reports supported by each BWP terminal device. In other words, the terminal device The number of periodic CSIs reported is within the capability of the terminal device.

Optionally, R is a positive integer less than or equal to P, the R CSI reports are R semi-persistent CSI reports, and the P is the maximum number of semi-persistent CSI reports supported by each BWP terminal device. In other words, The number of semi-persistent CSI reported by the terminal device is within the capability of the terminal device.

Optionally, R is a positive integer less than or equal to P, the R CSI reports are R aperiodic CSI reports, and P is the maximum number of aperiodic CSI reports supported by each BWP terminal device. In other words, The number of aperiodic CSI reported by the terminal device is within the capability of the terminal device.

Before step 402, the terminal device may also determine channel state information based on the configuration information of R CSI reports, and then send R CSI reports to the network device, where the R CSI reports carry channel state information.

One possible implementation is that on the first OFDM symbol, if there are L first CSI reports, to start calculating the channel state information, the terminal device needs to first calculate the occupied CPU (occupied CPU) on the first OFDM symbol. number, determine whether to determine the corresponding channel state information based on the configuration information reported by the L first CSI. Wherein, the L first CSI reports all occupy the CPU starting from the first OFDM symbol.

For example, if the sum of the number of occupied CPUs in each carrier in the first OFDM symbol and the number of CPUs corresponding to the L first CSI reports is greater than the threshold A, then the UE will, based on the priorities of the L first CSI reports, Only the channel state information of the W first CSI reports with higher priority is calculated (W is less than L). The number of CPUs corresponding to the W first CSI reports and the number of CPUs that have been occupied in each carrier in the first OFDM symbol are calculated. The sum of the number of CPUs is less than or equal to threshold A. Among them, threshold A is the maximum number of CPUs supported by the terminal device in each carrier. On the contrary, the terminal device calculates the channel state information reported by the L first CSI. This means that for other first CSI reports except W first CSI reports among the L first CSI reports, the terminal device will not determine the channel state information based on other first CSI reports except W first CSI reports. .

At the same time, if the sum of the number of occupied CPUs in all carriers in the first OFDM symbol and the number of CPUs corresponding to the L first CSI reporting configurations is greater than the threshold B, then the UE will, based on the priorities of the L first CSI reporting, Only the channel state information reported by the E CSI reports with higher priority is calculated (E is less than L), where the number of CPUs corresponding to the T first CSI reports and the number of CPUs that have been occupied among all carriers in the first OFDM symbol The sum of the number of CPUs is less than or equal to threshold B. On the contrary, the UE calculates the channel state information reported by the L first CSI, and the threshold B is the maximum number of CPUs supported by the terminal device in all carriers. This means that for other first CSI reports except W first CSI reports among the L first CSI reports, the terminal device will not determine the channel state information based on them.

In addition, for any periodic CSI reporting, the terminal device will determine the first time period based on its configuration information. The first time period is the occupied time period of K CPUs occupied by calculating the channel status information reported in the periodic CSI. If the first OFDM symbol is included in the first time period (and is not the first OFDM symbol in the first time period, that is, the periodic CSI reporting does not start from the first OFDM symbol), then within the first OFDM symbol The CPUs that have been occupied include the K CPUs. Also, if the terminal equipment calculates the channel state information of the L first CSI reports starting from the first OFDM symbol, and the periodic CSI report starts calculating the channel state information from the first OFDM symbol, then the L first CSI reporting includes CSI reporting in this period, and the L first CSI reporting CPUs include CPUs reporting in this period.

One possible way: for inactive periodic CSI reporting, determine that the number of CPUs occupied by it in the first time period is 0. For activated periodic CSI reporting, the number of CPUs occupied by the activated periodic CSI reporting in the first time period is determined based on its configuration information. Specifically, the number of CPUs occupied by the activated periodic CSI reporting in the first time period is determined based on the configuration information. , you can refer to the steps in TS 38.214. Among them, inactive CSI reporting can be understood as CSI reporting that has not taken effect, or CSI reporting that has not taken effect in the CSI reporting configuration, etc.

Another possible way: determine the number of CPUs occupied by activated periodic CSI reporting or inactive periodic CSI reporting in the first time period based on the configuration information (refer to the steps in TS 38.214). However, for inactive periodic CSI reporting, these CPUs are not actually occupied. Therefore, when calculating occupied CPUs on the first OFDM symbol, the number of occupied CPUs on the first OFDM symbol does not include the number of CPUs reporting inactive periodic CSI. Further, when determining the number of CPUs reporting L first CSI on the first OFDM symbol, the number of CPUs does not include the number of CPUs reporting inactive periodic CSI, or Said that the L first CSI reports do not include inactive periodic CSI reports.

Another possible way: determine the number of CPUs occupied by activated periodic CSI reporting or inactive periodic CSI reporting in the first period of time based on configuration information (refer to the steps in TS 38.214). However, when no activation indication information (such as the third indication information) is received, the length of the CPU occupation time period is 0, or the CPU occupation time period does not exist.

For the calculation method of the number of CPUs occupied by semi-persistent CSI reporting, you can refer to the above method and will not be described again.

When calculating CPU occupancy, by optimizing the calculation method of inactive periodic CSI reporting and semi-persistent CSI reporting, the UE will not be affected by the calculation of CPU occupancy of inactive periodic CSI reporting and inactive semi-persistent CSI reporting. Calculation and reporting of channel state information corresponding to priority CSI reporting.

Another possible implementation also needs to satisfy the number of activated CSI-RS resources and the number of CSI-RS ports on the activated BWP of the terminal device. For example, for periodic CSI-RS resources, once configured, the terminal device considers the periodic CSI-RS resources to be active CSI-RS resources, and the ports of the periodic CSI-RS resources to be active CSI-RS ports. Among them, periodic CSI reporting is associated with periodic CSI-RS resources. This may cause a waste of periodic CSI-RS resources that are configured but not activated.

One possible way: the periodic CSI-RS resources associated with the deactivated periodic CSI reporting are in the deactivated state, and the periodic CSI-RS resources associated with the activated periodic CSI reporting are in the activation state. In other words, the periodic CSI-RS resources associated with deactivated periodic CSI reporting are deactivated CSI-RS resources, and the periodic CSI-RS resources associated with activated periodic CSI reporting are activated CSI-RS resources.

Another possible way: while deactivating the periodic CSI reporting through the third indication information, deactivate the periodic CSI-RS resources associated with the periodic CSI reporting. In other words, the third indication information is used to deactivate periodic CSI reporting, and is also used to deactivate periodic CSI-RS resources associated with the periodic CSI reporting.

Another possible way: deactivate periodic CSI-RS resources through fifth indication information. That is to say, the above third indication information is used to deactivate periodic CSI reporting, and the fifth indication information is used to deactivate periodic CSI-RS resources.

This method can avoid the waste of unactivated CSI-RS resources, and at the same time, it can meet the capabilities of the terminal equipment and avoid the decrease in communication reliability caused by the limitation of the terminal equipment capabilities.

The terminal device selects R CSI reports from Q CSI reports. The possible methods are as follows:

Method A: The network device can indicate to the terminal device the CSI that needs to be reported.

For example, the network device sends third indication information to the terminal device. The third indication information is used to activate R CSI reports, and the R CSI reports belong to Q CSI reports. Optionally, R is a positive integer less than or equal to P.

In a possible implementation, the third indication information includes Q bits, the Q bits correspond to Q CSI reports one-to-one, and the value of each bit in the Q bits is used to indicate whether the corresponding CSI report belongs to R CSIs. Report. In other words, the third indication information may be a bit pattern (bitmap). The number of bit positions included in the bit pattern is the same as the number of CSI reports configured by the network device for the terminal device. The bits at different positions in the bit pattern have the same number. The value can be used to indicate whether the corresponding CSI needs to be reported.

In another possible implementation, the third indication information may be used to indicate the index of the R CSI reports. For example, the Q CSI reports correspond to Q indexes one-to-one, and the third indication information may be used to indicate R indexes among them.

In another possible implementation, the Q CSI reports belong to T sets, and the third indication information indicates the index number of at least one of the T sets, and the CSI reports included in the at least one set are the above R CSI reports. The T sets may be configured by RRC signaling. It can be understood that the CSI reports included in different sets in the T sets may or may not overlap, and this is not limited in the embodiment of the present application. It should also be understood that each set can also be a set of CSI reporting identifiers. For example, there are 6 CSI reporting identifiers, and the corresponding indexes are 1, 2, 3, 4, 5, and 6 respectively. The value of T is 3, and the 3 The set may be a set divided by the six identifiers. For example, set 1 includes identifiers 1 and 2, set 2 includes identifiers 3 and 4, and set 3 includes identifiers 5 and 6. In other words, the T sets only need to be able to instruct CSI reporting, and the content or form of the sets is not limited.

It should be understood that the third indication information may be used to indicate activated or effective CSI reporting, or may be used to indicate inactive or ineffective CSI reporting, or the third indication information may simultaneously indicate activated or effective CSI reporting. , and CSI reporting that is inactive or ineffective. The embodiments of the present application do not limit this.

Optionally, the third indication information may also be used to indicate QCL information of CSI measurement resources corresponding to the R CSI reports. For example, the third indication information may carry N TCI-stateIDs, which are used to match the QCL information of NZP-CSI-RSresource corresponding to the N activated CSI reported configuration information.

Optionally, the third indication information may be unicast DCI, unicast MAC CE, multicast DCI or multicast MAC CE.

The third indication information may be sent by the network device to a terminal device. For example, the third instruction information may be sent by the terminal device through a specific command of the terminal device. The RNTI scrambles the third indication information.

Alternatively, the third indication information is group common signaling. Alternatively, the third indication information can be scrambled through G-RNTI, and the third indication information can be received by a group of UEs at the same time. For the design of group common signaling, one way is that in the signaling, each UE corresponds to X bits. These X bits are used to indicate R of the above Q pieces of CSI configuration information. For a For a group of Y UEs, the group common signaling includes a total of X*Y bits. Another way is that all UEs share X bits in this group common signaling, and each UE performs the above method based on the X bits in this group common signaling, such as indicating the above Q CSI configuration information. R of them.

Optionally, for SP-CSI, the above third indication information indicates R of the Q CSI reference signals, which may indicate an index, or a predefined index set), which may be understood as activating the measurements corresponding to the Q CSI reference signals. R number of resource configurations, or R number of reported configurations associated with Q CSI reference signals. That is, the terminal device finds the activated CSI-RS in the configured SP CSI-RS set, or finds the activated CSI reporting configuration in the configured SP CSI reporting configuration. The terminal device reports the CSI report corresponding to the activated CSI measurement resource. Optionally, the reported information of the SP CSI is carried on the PUCCH.

Optionally, for the above situation of using multiple BWP configurations to carry Q CSI reporting configurations: the network device sends the third indication information to the terminal device, and the third indication information is used to indicate the Q pieces of CSI reporting configuration information. R CSI report configuration information takes effect. No matter which group of BWP configurations the R CSI-reportConfig is in, it takes effect and is reported in the first BWP. The first BWP is one of the two BWPs. In other words, the resource pool configured for CSI reporting by multiple BWPs can be shared.

Method B: Predefine the CSI that needs to be reported.

For example, the network device and the terminal device may predefine reporting conditions, and the reporting conditions may correspond to the capabilities of the terminal device. For example, the capability of the terminal device supports reporting of 4 CSIs, and the reporting condition may be to report 4 better CSIs. It should be understood that the best here can be determined based on all CSIs measured by the terminal device. For example, 6 CSIs are measured, and the first 4 median values of these 6 CSIs are reported from the largest to the smallest. For another example, the reporting condition may be a threshold, and the terminal device reports the CSI that reaches the threshold among the measured CSIs. Optionally, when the number of CSIs that reach the threshold is greater than the capability of the terminal device, the terminal device may report a part of the CSI that reaches the threshold, and the number of this part of the CSIs is within the capabilities of the terminal device. It should be understood that the threshold may be predefined, may be indicated by the network device, or may be determined by the terminal device based on multiple CSIs, which is not limited in the embodiments of the present application.

After determining the CSI that needs to be reported according to the above method, the terminal device can report the determined CSI to the network device.

Optionally, the terminal device can also report capability information to the network device. For example, the terminal device sends fourth indication information to the network device. The fourth indication information is used to indicate the value of Q. In other words, the fourth indication information is capability indication information, indicating that the terminal device can support determining from Q CSI reports. The finally sent CSI report may also indicate that the terminal device can store the configuration information of Q CSI reports, or may also indicate that the network device can be configured with Q CSI reports for the terminal device.

It should be understood that in the embodiments of this application, network equipment, terminal equipment, network equipment, and terminal equipment are used as examples to illustrate the solution. This application does not limit the types of equipment as the parties. For example, the network equipment is a network equipment and the terminal equipment is a terminal. Equipment, or network equipment is terminal equipment, and terminal equipment is terminal equipment; for another example, network equipment is network equipment, and terminal equipment is terminal equipment, or network equipment is terminal equipment, and terminal equipment is terminal equipment. The embodiments of the present application do not limit this. When the terminal device is a terminal device, it can be divided into two types: a first type of terminal device and a second type of terminal device. The first type of terminal device can be a low-capacity terminal device, such as storing or processing configurations reported by CSI The information capability is weak; the second type of terminal device may be a high-capacity terminal device, such as a strong ability to store or process configuration information reported by CSI. It should be understood that the level of this capability is relative, and terminal equipment with stronger capabilities may be developed in the future. Whether it is a first-type terminal device or a second-type terminal device, when the number of CSI reports that the terminal device supports to store or process is greater than the terminal capability defined by the current protocol, it can be called a terminal device with enhanced capabilities.

In this method, the network device configures the terminal device with CSI reporting configuration information that exceeds the capabilities of the terminal device, such as CSI-reportConfig. Multiple CSI-reportConfig respectively correspond to different measurement resources or measurement parameters, and the terminal device can be instructed through indication information. Activated or effective CSI-reportConfig enables terminal devices to break through capacity limitations and support more CSI reporting. When the measurement environment changes, for example, when the number of antenna ports changes, the terminal device can promptly call the measurement configuration corresponding to the new parameters, quickly and flexibly match the dynamically changing measurement environment, improve the measurement accuracy, and further improve the accuracy of the measurement. The quality of the communication that results.
