For the convenience of description, the terminal device will be described as an example of a terminal or UE hereinafter.

[0093] It should be understood that in some scenarios, the UE can also be used as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in V2X, D2D, etc. scenarios.

[0094] In the embodiments of the present application, the device for implementing the function of the terminal device, i.e., the terminal device, can be a terminal device or a device capable of supporting the terminal device to implement the function, such as a chip system or a chip or a circuit or a communication module (i.e., a communication module performing a communication function), which can be installed in the terminal device. In the embodiments of the present application, the chip system can be composed of a chip or can include a chip and other discrete devices. In addition, the device can also be configured with program instructions for performing corresponding communication functions.

[0095] The network device in the embodiments of the present application can be a device or a module with a corresponding communication function. The network device can be a device for communicating with the terminal device, and the network device can also be referred to as an access network device or a radio access network device, such as a network device, which can be a base station. The network device in the embodiments of the present application can refer to a radio access network (RAN) node (or device) for accessing the terminal device to a wireless network. The base station can broadly cover various names in the following or be replaced by the following names, such as: Node B (NodeB), evolved Node B (eNB), next generation Node B (gNB), relay station, access point, transmitting and receiving point (TRP), transmission point, primary station, secondary station, motor slide retainer (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. The base station can also refer to a communication module, a modem or a chip for being arranged in the foregoing device or apparatus. The base station can also be a mobile switching center and a device assuming a base station function in D2D, V2X, M2M communication, a device assuming a base station function in a future communication system, etc. The base station can support networks of the same or different access technologies. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the network device.

[0096] A base station can be fixed, or mobile. For example, a helicopter or unmanned aerial vehicle can be configured to function as a mobile base station, one or more cells can move according to the location of the mobile base station. In other examples, a helicopter or unmanned aerial vehicle can be configured to function as a device that communicates with another base station.

[0097] In some deployments, the network device mentioned by embodiments of the present application can be a device including a CU, or a DU, or a device including a CU and a DU, or a control plane CU node (central unit-control plane (CU-CP)) and a user plane CU node (central unit-user plane (CU-UP)) and a DU node. For example, the network device can include a gNB-CU-CP, a gNB-CU-UP and a gNB-DU.

[0098] In some deployments, a plurality of RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a CU, a DU, a CU-CP, a CU-UP, or a radio unit (RU) (or radio frequency unit), etc. The CU and the DU can be separately arranged, or can also be included in the same network element, such as a BBU. The RU can be included in a radio frequency device or a radio frequency unit, such as an RRU, an AAU or an RRH.

[0099] In some deployments, the CU is a logical node that hosts the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU is connected to network nodes such as core network via some interfaces, which can be E2 interface, etc. Optionally, the CU has part of the functions of the core network. The CU (e.g., PDCP layer and higher) is connected to the DU (e.g., radio link control (RLC) layer and lower) via some interfaces, which can be Fl interface, etc. In some examples, the interfaces (e.g., Fl interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transfer, etc.). The Fl application protocol (FlAP) is an application protocol for the Fl interface, which defines the signaling procedures for Fl in some examples. The Fl interface supports control plane (Fl-C), user plane (Fl-U).

[0100] In some deployments, a CU can be split into a CU-CP and a CU-UP. The CU-CP is a logical node that carries the control plane part of PDCP (PDCP-C) layer and RRC layer, and is used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network that is used to implement the control plane function. The network element in the core network that is used to implement the control plane function can be an access and mobility function network element. The CU-UP is a logical node that carries the user plane part of PDCP (PDCP-U) layer and SDAP layer, and is used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network that is used to implement the user plane function. The network element in the core network that is used to implement the user plane function. The above configurations of the CU and the DU are merely examples, and the CU and the DU can have other functions according to needs. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, partial functions of the RLC layer and functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of the protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to service types or other system requirements. For example, functions that need to meet a relatively short delay requirement in processing time are arranged in the DU, and functions that do not need to meet the delay requirement are arranged in the CU.

[0101] In some deployments, a DU is a logical node that carries an RLC layer, a medium access control (MAC) layer, a higher physical (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be a front-haul interface. In some examples, the Higher PHY layer includes part of the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and other processing functions.

[0102] In some deployments, a RU is a logical node that hosts lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, a RU can be a TRP or a RRH or other similar functional entity. In some examples, a Low-PHY includes portions of PHY processing such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming and filtering, and other processing functions. A RU communicates with one or more UEs over a wireless link.

[0103] A DU and a RU can or can not be co-located. A DU and a RU exchange control plane and user plane information over a fronthaul link via a lower-layer split-control, user and synchronization (LLS-CUS) interface. The LLS-CUS can include interfaces and interfaces that provide control plane and user plane, respectively. In some examples, the control plane refers to real-time control between a DU and a RU. A DU and a RU have an interface of a fronthaul link (e.g., referred to as a LLS-M interface) to exchange management information, and the management plane (M-Plane) refers to non-real-time management operations between a DU and a RU.

[0104] A DU and a RU can cooperate to collectively implement the functionality of a PHY layer. A DU can be connected to one or more RUs. The functionality that a DU and a RU have can be configured in multiple ways according to design. For example, a DU is configured to implement baseband functionality and a RU is configured to implement mid- RF functionality. As another example, a DU is configured to implement high-layer functionality in a PHY layer and a RU is configured to implement low-layer functionality in the PHY layer or to implement the low-layer functionality and RF functionality. The high-layer functionality in a PHY layer can include a portion of functionality of a PHY layer that is closer to a MAC layer, and the low-layer functionality in a PHY layer can include another portion of functionality of a PHY layer that is closer to a mid-RF side.

[0105] In one possible design, a processing unit in a BBU that implements baseband functionality is referred to as a base band high (BBH) unit, and a processing unit in a RRU / AAU / RRH that implements baseband functionality is referred to as a base band low (BBL) unit.

[0106] The CU (or CU-CP and CU-UP), DU, or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, the radio access network can also be an open radio access network (O-RAN) architecture, in which the CU can also be referred to as an open CU (O-CU), the DU can also be referred to as an open DU (O-DU), the CU-CP can also be referred to as an open CU-CP (O-CU-CP), the CU-UP can also be referred to as an open CU-UP (O-CU-UP), and the RU can also be referred to as an open RU (O-RU). Any of the CUs (or CU-CPs, CU-UPs), DUs, and RUs in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0107] In the embodiments of the present application, the device for implementing the function of the network device can be a network device, or a device capable of supporting the network device to implement the function, such as a chip system or a chip or a circuit or a communication module (i.e., a communication module performing a communication function), which can be installed in the network device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. In addition, program instructions for performing corresponding communication functions can also be configured in the device. In the embodiments of the present application, only the device for implementing the function of the network device is taken as an example for description, and the scheme of the embodiments of the present application is not limited.

[0108] The network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; and can also be deployed on aircraft, balloons, and satellites in the air. The embodiments of the present application do not limit the scenarios in which the network device and the terminal device are located. In addition, the terminal device and the network device can be hardware devices, or software functions running on special-purpose hardware, software functions running on general-purpose hardware, such as virtualized functions instantiated on a platform (e.g., a cloud platform), or entities including special-purpose or general-purpose hardware devices and software functions. The specific forms of the terminal device and the network device are not limited in the present application.

[0109] First, a communication system suitable for the embodiments of the present application is briefly introduced as follows.

[0110] Referring to FIG. 1, FIG. 1 is a schematic diagram of a wireless communication system suitable for the embodiments of the present application.

[0111] As shown in FIG. 1, the wireless communication system includes a radio access network 100. The radio access network 100 can be a next generation radio access network, or a legacy (e.g., 5G, 4G, 3G or 2G) radio access network. One or more terminal devices (120a-120j, collectively referred to as 120) can be connected to one or more network devices (110a, 110b, collectively referred to as 110) in the radio access network 100, or to each other. Network elements in the wireless communication system are connected through interfaces (e.g., next generation interface (NG), Xn), or air interfaces.

[0112] FIG. 1 is only a schematic diagram, and the wireless communication system can further include other devices, such as core network (CN) devices, wireless relay devices, and / or wireless backhaul devices, etc., which are not shown in FIG. 1.

[0114] The communication network elements shown in FIG. 2 are applicable to the communication between the network device and the terminal device in the network system of FIG. 1.

[0115] Referring to FIG. 3, FIG. 3 is another schematic diagram of a wireless communication system applicable to the embodiments of the present application.

[0116] As shown in FIG. 3, the wireless communication system can include core network devices, access network devices (e.g., RANs), terminal devices. The access network devices communicate with the core network devices through backhaul links and communicate with the terminal devices through air interfaces. For example, a BBU in the access network device communicates with the core network through a backhaul link, and a RU in the access network device communicates with the terminal device through an air interface. The BBU can communicate with the RU through a front-haul link, and the BBU and the RU can be co-located or not co-located. In some deployments, the BBU includes at least one CU and at least one DU, and the CU and the DU can communicate through a mid-haul link.

[0117] FIG. 3 is only a schematic diagram, and the wireless communication system can further include other devices, which are not shown in FIG. 3.

[0118] In order to better understand the technical solutions of the present application, some related technologies involved in the technical solutions of the present application are introduced.

[0119] 1. Beam: a kind of communication resource. Different beams can be considered as different resources. The same information or different information can be transmitted through different beams.

[0120] The beam in the NR protocol can be a spatial domain filter, or a spatial filter or a spatial parameter. The beam used for transmitting a signal can be referred to as a transmission beam (Tx beam), and the beam used for receiving a signal can be referred to as a reception beam (Rx beam).

[0121] The transmission beam can refer to the distribution of signal strength in different directions in space after the signal is transmitted from the antenna, and the reception beam can refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0122] In addition, the beam can be a wide beam, or a narrow beam, or other types of beams. The beam forming technology can be beam forming technology or other technology. The beam forming technology can be digital beam forming technology, analog beam forming technology, or hybrid digital / analog beam forming technology, etc.

[0123] One beam can correspond to one or more antenna ports, which are used to transmit data channels, control channels, and sounding signals, etc. One or more antenna ports corresponding to one beam can also be regarded as one antenna port set.

[0124] In this application, beam can be replaced by spatial filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, quasi-co-location (QCL) information, QCL assumption, QCL indication, transmission configuration indicator (TCI) state (TCI-state or TCI state), spatial relationship, etc. The above terms are also equivalent to each other. Beam can also be replaced by other terms representing beam, which is not limited in this application.

[0125] 2. Reference signal (RS): can also be called pilot, reference sequence, reference signal, etc. For the sake of unity, the following description is made with reference signal. Reference signal can be used for measurement, such as channel measurement or channel estimation, etc.

[0126] The channel measurement involved in this application also includes beam measurement, that is, the beam quality information is obtained by measuring the reference signal. As an example, the parameters used to measure the beam quality include at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR) (or can be simply referred to as signal-to-noise ratio). In the embodiments of this application, for the convenience of description, unless otherwise specified, the channel measurement involved can be regarded as beam measurement.

[0127] The reference signals involved in the present application may, for example, be any of the following: channel state information reference signals (CSI-RSs), synchronization signal blocks (SSBs), sounding reference signals (SRSs), user equipment specific reference signals (US-RSs), demodulation reference signals (DMRSs), phase tracking reference signals (PT-RSs), cell reference signals (CRSs), and the like. It should be understood that the reference signals listed above are merely examples and should not constitute any limitation on the present application. The present application does not rule out the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

[0128] 3. Reference signal resource: used to configure the transmission attributes of a reference signal, such as time-frequency resource location, port mapping relationship, power factor, and scrambling code, and the like. A transmitting end device can transmit a reference signal based on a reference signal resource, and a receiving end device can receive a reference signal based on a reference signal resource.

[0129] In order to distinguish different reference signal resources, at least one reference signal resource can correspond to a reference signal resource identifier, such as a CSI-RS resource indicator (CRI), an SSB resource indicator (SSBRI), and an SRS resource indicator (SRI).

[0130] In the embodiments of the present application, the reference signal quality and the reference signal resource quality are sometimes used alternately, and those skilled in the art should understand their meanings. The reference signal resource quality can be understood as the quality of a reference signal received based on the reference signal resource, or the signal quality measured based on the reference signal resource received and measured.

[0131] 4. Channel information: information capable of reflecting channel characteristics and channel quality.

[0132] As an example, the channel information is at least one of: channel state information (CSI), channel time variation information, or channel frequency offset information, etc. Hereinafter, the channel information is taken as an example of CSI, and it can be understood that information reflecting channel characteristics and channel quality is applicable to the embodiments of the present application.

[0133] Taking the network side obtaining the downlink CSI by the terminal device performing uplink feedback as an example, specifically, the network side sends a downlink reference signal to the terminal device, and the terminal device receives the downlink reference signal. Since the terminal device knows the transmission information of the downlink reference signal, the terminal device can estimate (or measure) the downlink channel experienced by the downlink reference signal based on the received downlink reference signal, and then the terminal device can generate CSI based on the measurement of the downlink channel matrix, and feed back the CSI to the network side.

[0134] As an example, the CSI includes at least one of: channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), CSI-RS resource indicator (CRI), layer indicator (LI), reference signal received power (RSRP), or signal to interference plus noise ratio (SINR), etc. The signal to interference plus noise ratio can also be referred to as signal to noise ratio.

[0135] 5. Reference signal configuration: The reference signal configuration can include two parts of reference signal resource configuration and reference signal reporting configuration. Hereinafter, the channel state information-reference signal (CSI-RS) configuration is taken as an example to introduce.

[0136] The two important parts of the CSI-RS configuration are “CSI-ReportConfig” and “CSI-ResourceConfig”. It can be understood that “CSI-ReportConfig” and “CSI-ResourceConfig” are only names adopted for convenience of description, and other names can also be used, which is not limited in the present application.

[0137] Among them, "CSI-ReportConfig" can be used to configure CSI reporting related parameters, such as "report configuration identifier (ReportConfigId)", "report configuration type (reportConfigType)", "report quantity (reportQuantity)" and the like. "reportConfigId" can be used to mark "CSI-ReportConfig", that is, one "reportConfigId" can correspond to one "CSI-ReportConfig". "reportConfigType" is used to configure the type of reporting, which can be divided into: periodic reporting, semi-persistent reporting and aperiodic reporting. "reportQuantity" can be used to configure the information of reporting, for example, including: CRI, PMI, RI, LI, CQI, RSRP, RSRQ, SNR, SINR and the like. Through different configurations, different information can be reported.

[0138] "CSI-ResourceConfig" can be used to configure CSI-RS resource related information, such as "CSI resource configuration identifier (CSI-ResourceConfigId)", and the CSI-RS resource used for measurement. Among them, "CSI-ResourceConfigId" is the identifier of "CSI resource configuration (CSI-ResourceConfig)", which is used to mark the "CSI-ResourceConfig", and through the variable, it can be associated with "CSI-ReportConfig".

[0139] Exemplarily, through the three high-level parameters "CSI-ResourceConfig"-"CSI-RS resource set (CSI-RS-ResourceSet)"-"CSI-RS-Resource", the network device can configure one or more CSI-RS resource sets for each terminal device, and each CSI-RS resource set includes one or more CSI-RS resources.

[0140] At least one CSI-RS resource can be identified by a "CSI-RS Resource Id". The identifiers of CSI-RS resources within a CSI-RS resource set are not necessarily sequential. For example, the identifiers (e.g., CSI-RS-ResourceIds) of resources in a CSI-RS resource set, ordered by beam index, may include {2 (bit value = 010), 4 (bit value = 100), 8 (bit value = 111), 3 (bit value = 011), 5 (bit value = 101)}. CSI-RS-ResourceId = 2 corresponds to resource index 0, CSI-RS-ResourceId = 4 corresponds to resource index 1, CSI-RS-ResourceId = 8 corresponds to resource index 2, CSI-RS-ResourceId = 3 corresponds to resource index 3, and CSI-RS-ResourceId = 5 corresponds to resource index 4. The resource index is used to indicate the transmission order of the CSI-RS resources; it should be understood that the resource index is merely an exemplary naming convention.

[0141] When the terminal device reports measurements based on the above configuration, the CRI in the CSI is used to indicate the resources in the current measurement CSI-RS resource set. If the CSI-RS resource set has Ks > 1 CSI-RS resources configured, CRI k (k is greater than or equal to 0) corresponds to the (k+1)th CSI-RS resource in the CSI-RS resource set for channel measurements, where k can be the value of CRI, or k can be the index of the resource indicated by CRI.

[0142] The table below is an example of the format of some fields in a measurement report.

[0143] As shown in Table 1, the CRI field carries the CRI, which indicates the CSI-RS resource to be reported, and its length is [length missing].

[0144] This indicates the number of CSI-RS resources in resource set s. This indicates rounding up. The SSBRI field carries the SSBRI, which indicates the SSB resource to be reported (such as the resource identifier), and its length is [length missing]. This indicates the number of SSB resources in resource set s. Terminal devices can report one or more of the following: CRI or SSBRI.

[0145] RSRP can adopt a differential reporting manner. For the maximum value of RSRP, 7-bit quantization can be adopted to report the absolute value of RSRP, as indicated by the RSRP field in the table. The RSRP indicated by the field corresponds to the reference signal resource corresponding to the reference signal with the maximum received power. Other RSRP can adopt 4-bit quantization to report the differential value between the RSRP and the maximum value of RSRP, as indicated by the differential RSRP field in the table.

[0146] The above takes the reporting quantity such as PMI, CRI, SSBRI, and RSRP as an example to briefly describe the measurement result, but this should not constitute any limitation on the present application. The present application does not limit the specific content contained in the measurement result and the indication manner thereof.

[0147] In the embodiments of the present application, the CSI can be carried in uplink control information (UCI) and transmitted through a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0148] Referring to FIG. 4, FIG. 4 is a schematic diagram of a CSI measurement reporting method 400 provided by the present application. The method 400 shown in FIG. 4 can include the following steps.

[0149] 410, the network device sends CSI reporting configuration information to the terminal device. Correspondingly, the terminal device receives the CSI reporting configuration information.

[0150] The CSI reporting configuration information is used to configure the terminal device with the measurement information that needs to be reported and the pilot resource that needs to be measured by the terminal device.

[0151] In a possible implementation, the network device can send at least one CSI reporting configuration information to the terminal device through one or more of RRC signaling, MAC-CE signaling, and DCI signaling.

[0152] Specifically, the CSI reporting configuration information includes CSI reporting configuration (CSI-ReportConfig) and CSI resource configuration (CSI-ResourceConfig).

[0153] CSI reporting configuration (CSI-ReportConfig) and CSI-resource configuration (CSI-ResourceConfig) can refer to the foregoing description and will not be described herein. As an example, the CSI reporting configuration information includes at least one CSI reporting configuration (CSI-ReportConfig). The at least one CSI reporting configuration is associated with one or more pilot resource sets (csi-rs-resourceSet), and one pilot resource set includes one or more pilot resources, which can be used for channel measurement or for interference measurement. The at least one pilot resource includes one or more pilot ports.

[0154] As an example, the pilot resource can be a non-zero power channel state information-reference signal resource (NZP CSIRS resource), a zero power channel state information-reference signal resource (ZP CSIRS resource), a channel state information-interference measurement resource (CSI-IM resource), or a synchronization signal block resource (SSB resource). Embodiments of the present application are not limited in this regard.

[0155] In a possible implementation, the CSI reporting configuration (CSI-ReportConfig) is associated with a pilot resource set (CSI-ResourceConfigId) for channel measurement, and the pilot resource set includes Ks pilot resources (Ks >= 1), which are divided into first-type pilot resources and second-type pilot resources. The first-type pilot resources include M R pilot resources, and the second-type pilot resources include Ks-M R pilot resources.

[0156] As an example, the first-type pilot resources can be high-priority pilot resources, and the second-type pilot resources can be ordinary pilot resources, which can be understood as pilot resources with a priority lower than that of the first-type pilot resources. In other words, the priority of the first-type pilot resources is higher than that of the second-type pilot resources.

[0157] As an example, the first type of pilot resource is the pilot resource indicated by the network device for which the channel state information needs to be reported. The second type of pilot resource is the pilot resource from which the terminal device selects part of the pilot resource or all of the pilot resource for reporting the channel state information.

[0158] The following specific description indicates how to indicate the first type of pilot resource and the second type of pilot resource in the CSI reporting configuration (CSI-ReportConfig). At least one of the following manners is included:

[0159] Manner one: a new field is defined in the parameter list of the CSI reporting configuration (CSI-ReportConfig) to indicate M R first type of pilot resources.

[0160] As an example, the field is “highPriorityCRI”, as shown below:

[0161] Manner two: a new field is defined in the parameter list of the CSI reporting configuration (CSI-ReportConfig), and the CSI reporting configuration (CSI-ReportConfig) is associated with another CSI reporting configuration (associatedCSI-ReportConfig) to establish a plurality of CSI reporting configuration (CSI-ReportConfig) association relationships. The field defined in the CSI reporting configuration (CSI-ReportConfig) is used to indicate M R first type of pilot resources. In addition to the pilot resource priority information, all other parameter configurations can reuse the specific configurations of the associated CSI reporting configuration (associatedCSI-ReportConfig).

[0162] As an example, the field is “highPriorityCRI”, and the plurality of pilot resources for channel measurement contained in the associated CSI reporting configuration (associatedCSI-ReportConfig) are all second type of pilot resources. As shown below:

[0163] Manner three: a new field is defined in the parameter list of the non-zero power CSI RS resource set (NZP-CSI-RS-ResourceSet) associated with the CSI reporting configuration (CSI-ReportConfig) for channel measurement to indicate M R first type of pilot resources.

[0164] As an example, the field is "highPriorityCRI", as shown below:

[0165] Method 4: A new field is defined in the parameter list of CSI reporting configuration (CSI-ReportConfig) to indicate the number of first type reference signal resources and which reference signal resources are the first type reference signal resources.

[0166] As an example, the field is "M R ", as shown below, to indicate the number of first type reference signal resources:

[0167] Method 5: A new field is defined in the parameter list of non-zero power CSI-RS resource set (NZP-CSI-RS-ResourceSet) associated with the CSI reporting configuration (CSI-ReportConfig) for channel measurement to indicate the number of first type pilot resources and which pilot resources are the first type pilot resources.

[0168] As an example, the field is "M R ", as shown below:

[0169] Method 6: A new field is defined in the parameter list of non-zero power CSI-RS resource contained in the non-zero power CSI-RS resource set (NZP-CSI-RS-ResourceSet) associated with the CSI reporting configuration (CSI-ReportConfig) for channel measurement to indicate whether the non-zero power CSI-RS resource is the first type pilot resource.

[0170] As an example, the field is "highPriorityCRIFlag", as shown below:

[0171] Method 7: The CSI reporting configuration and the first type pilot resource associated with the CSI reporting configuration are indicated by a field in DCI signaling.

[0172] As an example, the field is the "CSI request" field in DCI signaling, assuming the number of bits occupied by the "CSI request" field is N, where N1 bits are used to indicate the CSI reporting configuration identifier, N2 bits are used to indicate the M R high priority pilot resources associated with the CSI reporting configuration, and N1+N2=N.

[0173] The following example illustrates the specific definitions of the above fields. Assume that the non-zero power CSIRS resource set (NZP-CSI-RS-ResourceSet) associated with the CSI reporting configuration (CSI-ReportConfig) for channel measurement contains 4 (Ks=4) non-zero power CSIRS resources, which are {NZP-CSI-RS-ResourceId=n1, NZP-CSI-RS-ResourceId=n2, NZP-CSI-RS-ResourceId=n3, NZP-CSI-RS-ResourceId=n4}.

[0174] For example, the specific definition rules for the N2 bits of the above field "highPriorityCRI" or the DCI signaling field "CSI request" are as follows:

[0175] Rule 1: Display the indicator M in bitmap format. R For each type of pilot resource, one bit corresponds to one pilot resource. A bit value of 0 indicates that the pilot resource is a type 2 pilot resource, and a bit value of 1 indicates that the pilot resource is a type 1 pilot resource. Rule 1 can include the following two rules ① and rule ②:

[0176] Rule ①: High-order bits correspond to pilot resources with smaller CRI.

[0177] For example, 0101 indicates that the pilot resources with non-zero power channel state information-reference signal resource identifier (NZP-CSI-RS-ResourceId) = n2 and NZP-CSI-RS-ResourceId = n4 are the first type of pilot resources, and the pilot resources with NZP-CSI-RS-ResourceId = n1 and NZP-CSI-RS-ResourceId = n3 are the second type of pilot resources.

[0178] Rule 2: Higher bits correspond to pilot resources with larger CRI.

[0179] For example, 0101 indicates that the pilot resource with NZP-CSI-RS-ResourceId=n1 and the pilot resource with NZP-CSI-RS-ResourceId=n3 are high priority pilot resources, and the pilot resource with NZP-CSI-RS-ResourceId=n2 and the pilot resource with NZP-CSI-RS-ResourceId=n4 are normal pilot resources.

[0180] Rule two: a plurality of CRI values are indicated in the form of a plurality of fields, and the bit corresponding to one CRI value = log2(K S ), and one CRI value corresponds to one pilot resource; the total number of bits occupied by the field = M R *log2(K S ); the specific value of M R may be pre-agreed by a protocol, or one of the above-mentioned ways three or four is indicated to the terminal device by the network device.

[0181] Rule three: a plurality of pilot resource combinations are indicated in the form of one field, and one value corresponds to one combination of M R pilot resources; the number of bits occupied by the field is related to the value of M R and the value of Ks.

[0182] For example, the number of bits occupied by the field Assuming that M R = 1 and Ks = 4, the number of bits occupied by the field By default, the pilot resources are sorted in ascending order of pilot resource index (CRI), and “00” indicates that the pilot resource ranked first is the first type of pilot resource, and the other pilot resources are the second type of pilot resource; “01” indicates that the pilot resource ranked second is the first type of pilot resource, and the other pilot resources are the second type of pilot resource; and so on. The specific value of M R may be pre-agreed by a protocol, or one of the above-mentioned ways three or four is indicated to the terminal device by the network device.

[0183] For example, the specific definition rule of the above-mentioned new field “M R ” is one or more of the following:

[0184] Rule four: the pilot resources are sorted in ascending order of pilot resource index (CRI), and the first M R pilot resources are the first type of pilot resource, and the other Ks-M R pilot resources are the second type of pilot resource.

[0185] For example, M R = 0 indicates that all pilot resources are the second type of pilot resource.

[0186] As an example, M R = 1 means that the Ks pilot resources associated with the CSI reporting configuration (CSI-ReportConfig) contain 1 first type of pilot resource and Ks-1 second type of pilot resource; where the pilot resource with NZP-CSI-RS-ResourceId = n1 in the pilot resource list is the first type of pilot resource, and other pilot resources are the second type of pilot resource.

[0187] As an example, M R = 2 means that the Ks pilot resources associated with the CSI reporting configuration (CSI-ReportConfig) contain 2 first type of pilot resource and Ks-2 second type of pilot resource; where the pilot resource with NZP-CSI-RS-ResourceId = n1 and NZP-CSI-RS-ResourceId = n2 in the pilot resource list are the first type of pilot resource, and other pilot resources are the second type of pilot resource; and so on.

[0188] Rule five: according to the pilot resource identifier (NZP-CSI-RS-ResourceId) from small to large, the first M R pilot resources are the first type of pilot resource, and the other Ks-M R pilot resources are the second type of pilot resource. It is assumed that the pilot resource identifier takes the value n2 > n4 > n1 > n3.

[0189] As an example, M R = 0 means that all pilot resources are the second type of pilot resource.

[0190] As an example, M R = 1 means that the Ks pilot resources associated with the CSI reporting configuration (CSI-ReportConfig) contain 1 first type of pilot resource and Ks-1 second type of pilot resource; where the pilot resource with NZP-CSI-RS-ResourceId = n3 in the pilot resource list is the first type of pilot resource, and other pilot resources are the second type of pilot resource.

[0191] As an example, M R = 2 means that the Ks pilot resources associated with the CSI reporting configuration (CSI-ReportConfig) contain 2 first type of pilot resource and Ks-2 second type of pilot resource; where the pilot resource with NZP-CSI-RS-ResourceId = n3 and NZP-CSI-RS-ResourceId = n1 in the pilot resource list are the first type of pilot resource, and other pilot resources are the second type of pilot resource; and so on.

[0192] As an example, the specific definition rule of the new field "highPriorityCRIFlag" is as follows:

[0193] Rule six: true indicates that the pilot resource is the first type of pilot resource.

[0194] Rule seven: false indicates that the pilot resource is the second type of pilot resource.

[0195] As an example, the report configuration type (reportConfigType) of the CSI reporting configuration (CSI-ReportConfig) can be periodic, or semi-static with PUCCH, or semi-static with PUSCH, or aperiodic, or triggered.

[0196] It should be understood that the field names described in the above manners are only examples, and the term names do not cause any limitation to the present application.

[0197] It should be understood that the pilot resource described in the present application can also be referred to as a reference signal resource, a reference signal pilot resource, a channel state information reference signal resource, etc., and the term names do not cause any limitation to the present application.

[0198] As an example, the report quantity (reportQuantity) of the CSI reporting configuration is one or more of the following:

[0199] 'cri-RSRP' or'ssb-Index-RSRP' or 'cri-SINR' or'ssb-Index-SINR' or 'cri-RSRP-Index' or'ssb-Index-RSRP-Index' or 'cri-SINR-Index', or'ssb-Index-SINR-Index'; 'cri-RI-PMI-CQI' or 'cri-RI-LI-PMI-CQI', or 'cri-RI-CQI' or 'cri-RI-i1-CQI' or 'cri-RI-i1'.

[0200] 420, the terminal device performs CSI measurement.

[0201] The terminal device performs receiving measurement on the relevant pilot resource based on the CSI reporting configuration information, in other words, the terminal device performs measurement through the reference signal received on the relevant pilot resource to obtain the CSI.

[0202] Among them, the reference signal is a downlink reference signal. For example, the reference signal is a CSI-RS, and correspondingly, the reference signal resource is a CSI-RS resource (resource).

[0203] As an example, the CSI reporting configuration configured by the network device is associated with Ks resources for channel measurement. The terminal device can select M pilot resources from the Ks resources for channel state information measurement. The obtained channel state information of at least one pilot resource of the M pilot resources includes one or more of the following: RI, wideband CQI of the first transport block, subband CQI of the first transport block, wideband CQI of the second transport block, subband CQI of the second transport block, wideband PMI, subband PMI, and layer indication LI.

[0204] As an example, the M pilot resources include M R first-type pilot resources and M-M R second-type pilot resources. For ease of description, the M R first-type pilot resources can be referred to as first pilot resources, and the M-M R second-type pilot resources can be referred to as second pilot resources. The term names do not cause any limitation to the present application.

[0205] Specifically, for example, the network device configures 8 pilot resources for channel measurement. In csiReportConifg->resourcesForChannelMeasurement->nzp-CSI-RS-ResourceSetList->nzp-CSI-RS-ResourceSet, 8 NZP CSI RS resources {NZP-CSI-RS-ResourceId=n0, NZP-CSI-RS-ResourceId=n1, NZP-CSI-RS-ResourceId=n2, NZP-CSI-RS-ResourceId=n3, NZP-CSI-RS-ResourceId=n4, NZP-CSI-RS-ResourceId=n5, NZP-CSI-RS-ResourceId=n6, NZP-CSI-RS-ResourceId=n7} are included. The terminal device can select channel state information of 4 pilot resources from the 8 pilot resources for reporting, which can be channel state information corresponding to {NZP-CSI-RS-ResourceId=n1, NZP-CSI-RS-ResourceId=n3, NZP-CSI-RS-ResourceId=n4, NZP-CSI-RS-ResourceId=n6}, respectively.

[0206] For another example, the channel state information corresponding to NZP-CSI-RS-Resourceld=n1 is one or more of the following: rank=RI#n1, wideband CQI for the first transport block=wbCQI#n1_0, subband CQI for the first transport block=sbCQI#n1_0, wideband CQI for the second transport block=wbCQI#n1_1, subband CQI for the second transport block=sbCQI#n1_1, wideband PMI=wbPMI#n1, and subband PMI=sbPMI#n1; the channel state information corresponding to NZP-CSI-RS-Resourceld=n6 is one or more of the following: rank=RI#n6, wideband CQI for the first transport block=wbCQI#n6_0, subband CQI for the first transport block=sbCQI#n6_0, wideband CQI for the second transport block=wbCQI#n6_1, subband CQI for the second transport block=sbCQI#n6_1, wideband PMI=wbPMI#n6, and subband PMI=sbPMI#n6.

[0207] The method for the terminal device to determine the M pilot resources from the Ks pilot resources is not limited by the embodiments of the present application.

[0208] 430, the terminal device performs CSI reporting.

[0209] The terminal device reports at least one of the following channel state information to the network device based on the pilot measurement result of S420: M pieces of CSI corresponding to the M pilot resources selected from the Ks pilot resources configured for channel measurement are reported to the network device.

[0210] Currently, using more spectrum resources is an important means to improve the capability of wireless channels, and the 6G frequency band has become the next spectrum resource available for wireless communication. As the frequency band is higher, the signal energy transmission loss is greater under the same transmission distance. In order to overcome this problem, a larger antenna array is usually used on the network device side to perform weighting processing on the transmitted signal to obtain higher array gain and thus improve the transmission energy of the signal. In order to reduce the implementation cost, the large-scale antenna array on the network device side usually adopts a hybrid beamforming (HBF) architecture, that is, one digital channel drives multiple antenna elements through multiple phase shifters, and the network device side usually adopts two-stage weights in the analog and digital domains for downlink signal transmission.

[0211] Referring to FIG. 5, FIG. 5 is a schematic diagram of a network device side HBF architecture. As shown in FIG. 5, under the HBF architecture, the network device usually adopts multiple analog beams to implement coverage of different areas in a cell, and different analog beams cover different terminal devices. Considering a medium-low frequency band, the channel environment is rich in multipath, and the same terminal device can be served by different analog beams, that is, in addition to the optimal analog beam seen by the terminal device, other non-optimal analog beams can also provide data transmission for the terminal device at a lower rate. When there are multiple terminal devices to be scheduled in the cell, to enable simultaneous transmission of multiple terminal devices under resource multiplexing in the cell, the terminal device can measure the channel state information under multiple analog beams, thereby providing input for data scheduling decision of the network device.

[0212] Specifically, the configuration for reporting channel state information contains one or more reference signal resource sets, at least one reference signal resource set contains one or more reference signal resources, and at least one reference signal resource contains one or more reference signal ports, wherein for the HBF architecture, different analog beams are associated with different reference signal resources. When the transmission signals of multiple reference signal resources contained in the same reference signal resource set all come from the same network device (such as a TRP), the current protocol only supports the terminal device to select a certain reference signal resource from them and report the channel state information to the network device side. Through the CRI reporting value, the network device is informed of a certain reference signal resource associated with the currently reported CSI information. Wherein, the specific selection of which reference signal resource for CSI reporting is autonomously decided by the terminal device.

[0213] Based on the existing protocol, the network device can configure multiple reference signal resources for the terminal device to measure channel state information, that is, different analog beams can be configured as different reference signal resources, and the terminal device can perform reception measurement on different reference signal resources to obtain channel state information and report a measurement report to the access network device. However, the receiving end can report multiple measurement reports when reporting the measurement report, or can carry the channel state information corresponding to multiple reference signals in the same measurement report. How to report the measurement report is a technical problem to be solved.

[0214] Therefore, the present application proposes a communication method, which can make the receiving end report multiple measurement reports according to certain rules, or carry the channel state information corresponding to multiple reference signals in one measurement report.

[0215] Before introducing the scheme of the present application, the following points are explained.

[0216] (1) In the present application, "indication" can include direct indication, indirect indication, display indication, and implicit indication. When describing that certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0217] In the present application, the information indicated by the indication information is referred to as to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, a protocol stipulates), thereby reducing the indication overhead to a certain extent. In addition, the to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending time of these sub-information can be the same or different.

[0218] (2) In the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be carried out between devices, for example, between network devices and terminal devices, or can be carried out within a device, for example, between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0219] (3) In various embodiments of the present application, the terms and / or descriptions of different embodiments are consistent and can be mutually referenced if there is no special description and logical conflict. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0220] (4) In the present application, "first", "second", and "#1", "#2", and "#n1", "#n2", etc. are only for convenience of description, used to distinguish objects, and do not limit the scope of the embodiments of the present application. They are not used to describe the order or sequence of features. It should be understood that the objects thus described can be interchanged under appropriate circumstances, so as to be able to describe solutions other than the embodiments of the present application.

[0221] (5) In the present application, "predefined" can mean a standard protocol predefined, or can also mean pre-agreed or pre-negotiated between devices.

[0222] (6) In the present application, words such as "exemplarily", "such as" and the like are used to represent examples, illustrations or descriptions. Any embodiment or design scheme described as "example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the word "example" is used to present the concept in a specific way. In the embodiments of the present application, "of", "corresponding" and "corresponding" can be used interchangeably at times. It should be pointed out that when their differences are not emphasized, their meanings expressed are consistent.

[0242] As an example, the M channel state information is contained in a channel state information field (CSI field) which can be carried in uplink control information (UCI) and transmitted through a physical uplink control channel PUCCH or PUSCH.

[0243] The second CSI report includes a CSI field corresponding to M channel state information reference signal resource indicators CRIs, the M CRIs one-to-one corresponding to the M reference signal resources, in other words, the M channel state information is contained in the CSI fields indicated by the M CRIs.

[0259] In a possible implementation, the second CSI report contains one part (Part #n), or in other words, each part of channel state information contains one part.

[0260] In another possible implementation, the second CSI report contains two parts, a first part (Part 1) and a second part (Part 2), or in other words, each part of channel state information contains two parts.

[0261] It should be understood that in this application, the first part (Part 1) is equivalent to the first part CSI (Part 1 CSI), and the second part (Part 2) is equivalent to the second part CSI (Part 2 CSI), and the term names do not limit this application.

[0270] It should be noted that the second CSI report includes two parts (Part 1 and Part 2), and the second part can include wideband CSI (Part 2 wideband CSI) and subband CSI (Part 2 subband CSI). The second field can be understood as the second part wideband CSI (Part 2 wideband CSI), and the third field can be understood as the second part subband CSI (Part 2 subband CSI).

[0271] In a possible implementation, the CSI report on the PUSCH includes two parts, and the UE can omit the second part CSI.

[0272] In a possible implementation, the UE can omit the second part CSI according to the priority of the second part CSI. In other words, the UE can omit the second part CSI information of a certain priority according to the priority of the second part CSI. It can be understood that omission or omission can be understood as not reporting part of the CSI information, and other terms can also be used instead, for example, based on the above English interpretation.

[0276] Exemplarily, one of the one M reference signal resources can correspond to one of the one CSI report. For example, one CSI report contains 4 resources, the four resources correspond to one of the one M reference signal resources, the fields in Part 1 and Part 2 of one of the one M reference signal resources can refer to the description above.

[0277] The following first describes the ordering rules of the CSI fields of the embodiments of the present application.

[0278] The following Tables 1-6 show format examples of CSI field ordering applicable to the embodiments of the present application, where the CSI fields indicate M channel state information corresponding to M reference signal resources and the order of the M channel state information.

[0279] The CRI field is used to carry a reference signal resource index value, CRI k0-CRI k M-1 are used to indicate M channel state information resource indexes to be reported. At least one CRI field corresponds to a reference signal resource associated with one channel state information, for example, M reference signal resource indexes are k0, k1, k2, …, k M-1 CRI k0 indicates the reference signal resource with index k0, and the channel state information of the reference signal resource is prioritized first and occupies the most important bit of the CSI field.

[0280] CRI k0-CRI k M-1 The M channel state information resources indicated by the CRI fields are arranged in order of priority.

[0281] Exemplarily, the M CRIs are indicated in the form of CRI k0, CRI k1, …, CRI k m , …, CRI k M-1 , where k m and m are integers, k m is used to indicate the index of the Ks resources of the CSI-RS resource set configuration, M is the number of reported beams, k m corresponding to 0≤k m <Ks, m corresponding to 0≤m<M.

[0282] Exemplarily, consider that the base station end configures M R high priority beams, the corresponding M CRIs are indicated in the form of CRI k0, CRI k1, …, CRI k MR , …, CRI k m , …, CRI k M-1 , where k m and m are integers, km Indexes of Ks resources for indicating CSI-RS resource set configuration, M is the number of reported beams, k m corresponding value is 0 ≤ k m <Ks, m corresponding value is 0 ≤ m < M.

[0283] Exemplarily, in this CSI field, channel state information resources with higher priority occupy bit positions with higher importance, and channel state information resources with lower priority occupy bit positions with relatively lower importance. For example, channel state information resources with higher priority occupy the front bit positions in the CSI field, and channel state information resources with lower priority occupy the rear bit positions in the CSI field. For example, the reference signal resources indicated by the CRI k0 field have the highest priority, and the CRI k M-1 field indicates the reference signal resources with the lowest priority, and the priorities of the M reference signal resources indicated by CRI k0 - CRI k M-1 are getting lower and lower.

[0284] Among them, the channel state information content corresponding to the reference signal resources indicated by at least one of the CRI k0 - CRI k M-1 fields can be determined according to the configuration information of the network device. For example, in step 410 of method 400, the network device configures the reported information in the report quantity (reportQuantity) in the CSI reporting configuration (CSI-ReportConfig), such as including at least one of the following: CRI, PMI, RI, LI, CQI, RSRP, RSRQ, SNR, SINR, etc. Through different configurations, different information can be reported.

[0285] Exemplarily, M - M R CRIs are indicated in the form of CRI k0, CRI k1,..., CRI k m ,..., CRI k M-MR-1 where k m and m are integers, k m Indexes of Ks resources for indicating CSI-RS resource set configuration, M is the number of reported beams, k m corresponding value is 0 ≤ k m <Ks, m corresponding value is 0 ≤ m < M - M R .

[0286] Exemplarily, when the M reference signal resources include M R (M R > 0) first type of reference signal resources, that is, the access network device configures M RWhen the number of high priority beams is M, the corresponding CRI can not be fed back, and the fed back M channel state information can feed back M-M R CRI, and the M-M R CRI can be indicated by index CRI k0-CRI k M-MR-1 , and the channel state information corresponding to CRI k0 can be arranged in the first position of M-M R channel state information.

[0287] For example, when the M reference signal resources include M R (MR>0) first type reference signal resources, the channel state information corresponding to the M R first type reference signal resources can be arranged before the channel state information corresponding to the M-M R second type reference signal resources, or can be arranged according to other rules, for example, the channel state information corresponding to the M R first type reference signal resources and the channel state information corresponding to the M-M R second type reference signal resources can be arranged based on CQI, RSRP, RI, etc. measurement results. The embodiments of the present application are not limited in this regard.

[0288] The following are examples of the first part of the CSI report of M channel state information (Table 1-Table 6).

[0289] In one possible implementation, the above-mentioned M reference signal resources do not include M R reference signal resources configured by the access network device. Then, the first part CSI corresponding to the M reference signal resources is arranged in the order of CRI, first arranging the first part of the channel state information corresponding to the reference signal resource indicated by CRI k0, then arranging the first part of the channel state information corresponding to the reference signal resource indicated by CRI k1, and so on. As shown in Table 1 and Table 2.

[0290] For example, one or more fields in the first part of the channel state information corresponding to the reference signal resource indicated by at least one CRI are arranged in the following order: CRI, RI, wideband CQI in the first TB, and subband differential CQI in the first TB in increasing order of subband number. Taking CRI k0 as an example, the field adjacent to the CRI k0 field to the field adjacent to the front of the CRI k1 field is used to carry the Part1 of the channel state information corresponding to the reference signal resource indicated by CRI k0. The specific CSI field format is shown in Table 1.

[0291] For example, one or more fields of the CSI Part 1 field corresponding to the M reference signal resources of the CSI report #1 are arranged as follows:

[0292] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB} associated with the 1st CSI-RS resource in the M reference signal resources;

[0293] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB} associated with the 2nd CSI-RS resource in the M reference signal resources;

[0294] ……;

[0295] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB} associated with the Mth CSI-RS resource in the M reference signal resources.

[0296] For example, at least one or more fields in the first part of the channel state information corresponding to the reference signal resource indicated by the at least one CRI are arranged in the following order: CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB in increasing order of subband number, indicator K of the sum of non-zero coefficients of all layers NZ For example, the CRI k0 field and the adjacent next field to the CRI k0 field to the adjacent previous field to the CRI k1 field are used to carry the first part of the channel state information corresponding to the reference signal resource indicated by the CRI k0. The specific CSI field format is shown in Table 2.

[0297] For example, one or more of the CSI Part 1 fields corresponding to the M resources of the CSI report #1 are arranged as follows:

[0298] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers} associated with the 1st CSI-RS resource in the M reference signal resources NZ};

[0299] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers} associated with the 2nd CSI-RS resource in the M reference signal resources NZ};

[0300] ……;

[0301] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers} associated with the Mth CSI-RS resource in the M reference signal resources Nz}.

[0302] Table 1

[0303] Table 2

[0304] In the above Table 1 and Table 2, the M CRIs are indicated in the form of CRI k0, CRI k1, …, CRI k m , …, CRI k M-1 , where k m and m are integers, k m is used to indicate the index of the Ks resources of the CSI-RS resource set configuration, M is the number of reported beams, and the corresponding value of k m is 0 ≤ k m < Ks, and the corresponding value of m is 0 ≤ m < M.

[0305] It should be noted that the above Table 1 and Table 2 are only for illustrative purposes and should not be used to limit the embodiments of the present application. The new table content obtained by reasonable deformation, supplementation or deletion of the content in Table 1 and Table 2 all fall within the protection scope of the embodiments of the present application.

[0306] In a possible implementation, the above M reference signal resources include M R reference signal resources configured by the access network device. Then, the first part of the CSI corresponding to the M reference signal resources is arranged in the order that the priority of the M R reference signal resources is higher than that of the M - M R reference signal resources. First, the CSI fields of the M R reference signal resources are arranged, and then the CSI fields of the M - M R reference signal resources are arranged. For example, first arrange the first part of the channel state information corresponding to the reference signal resource indicated by CRI k0, then arrange the first part of the channel state information corresponding to the reference signal resource indicated by CRI k1, ……, then arrange the first part of the channel state information corresponding to the reference signal resource indicated by CRI k MR-1 , and then arrange the first part of the channel state information corresponding to the reference signal resource indicated by CRI k)] MR , ……, then arrange the first part of the channel state information corresponding to the reference signal resource indicated by CRI k M-1 , and so on. As shown in Tables 3 - 6 below.

[0307] It should be noted that when the M reference signal resources include M R reference signal resources configured by the access network device, the first part of the CSI corresponding to the M R reference signal resources is not necessarily arranged before the first part of the CSI corresponding to the M - M R reference signal resources. For example, based on M RM R The arrangement order is determined by at least one of the following parameters corresponding to the M reference signal resources: CSI-RS resource indication CRI, rank indication RI, precoding matrix indication PMI, channel quality indication CQI, and the like. Embodiments of the present application do not limit the arrangement order.

[0308] For example, the fields in the first part of the channel state information corresponding to the at least one CRI indicated reference signal resource are arranged in the following order: CRI, RI, wideband CQI in the first TB, and subband differential CQI in the first TB in ascending order of subband number. Taking CRI k0 as an example, the field adjacent to the CRI k0 field and the field adjacent to the CRI k1 field are used to carry the first part of the channel state information corresponding to the CRI k0 indicated reference signal resource. The specific CSI field format is shown in Table 3 and Table 4.

[0309] For example, the CSI Part 1 fields corresponding to the M reference signal resources of the CSI report #1 are arranged as follows:

[0310] The {CRI, RI, wideband CQI in the first TB, and subband differential CQI in the first TB} associated with the first CSI-RS resource in the M reference signal resources;

[0311] The {CRI, RI, wideband CQI in the first TB, and subband differential CQI in the first TB} associated with the second CSI-RS resource in the M reference signal resources,

[0312] ...

[0313] The {CRI, RI, wideband CQI in the first TB, and subband differential CQI in the first TB} associated with the M R CSI-RS resource in the M reference signal resources;

[0314] The {CRI, RI, wideband CQI in the first TB, and subband differential CQI in the first TB} associated with the M R +1 CSI-RS resource in the M reference signal resources;

[0315] ...

[0316] The {CRI, RI, wideband CQI in the first TB, and subband differential CQI in the first TB} associated with the M CSI-RS resource in the M reference signal resources.

[0317] The CSI fields of the M R reference signal resources can not include CRI.

[0318] For example, one or more fields in the first part of the channel state information corresponding to at least one CRI-indicated reference signal resource are arranged in the following order: RI, wideband CQI in the first TB, subband differential CQI in the first TB in ascending order of subband number, and indicator K of the sum of non-zero coefficients of all layers. NZ Taking CRI k0 as an example, the field immediately following the CRI k0 field to the field immediately preceding the CRI k1 field carries the first part of the channel state information corresponding to the reference signal resource indicated by CRI k0. The specific CSI field formats are shown in Tables 5 and 6 below.

[0319] For example, one or more of the CSI Part 1 fields corresponding to the M reference signal resources in CSI report #1 are arranged as follows:

[0320] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers} are associated with the first CSI-RS resource out of M reference signal resources. Nz};

[0321] The second CSI-RS resource associated with M reference signal resources {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers}. NZ};

[0322] ...;

[0323] The Mth reference signal resource R The CSI-RS resource is associated with {CRI, RI, the broadband CQI in the first TB, the subband differential CQI in the first TB, and the indicator K for the sum of non-zero coefficients across all layers}. Nz};

[0324] The Mth reference signal resource R +1 CSI-RS resource associated with {CRI, RI, broadband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers}. NZ};

[0325] ...;

[0326] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers} are associated with the Mth CSI-RS resource among M reference signal resources. NZ}

[0327] Among them, M RThe CSI field of a reference signal resource may not include CRI.

[0328] For example, one or more of the CSI Part 1 fields corresponding to the M reference signal resources in CSI report #1 are arranged as follows:

[0329] {RI, broadband CQI in the first TB, subband differential CQI in the first TB, and indicator K of the sum of non-zero coefficients of all layers} are associated with the first CSI-RS resource out of M reference signal resources. NZ};

[0330] {RI, broadband CQI in the first TB, subband differential CQI in the first TB, and indicator K of the sum of non-zero coefficients of all layers} are associated with the second CSI-RS resource out of M reference signal resources. NZ};

[0331] ...;

[0332] The Mth reference signal resource R {RI, broadband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers} are associated with each CSI-RS resource. NZ};

[0333] The Mth reference signal resource R +1 CSI-RS resource associated with {CRI, RI, broadband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers}. NZ};

[0334] ...;

[0335] {CRI, RI, wideband CQI in the first TB, subband differential CQI in the first TB, indicator K of the sum of non-zero coefficients of all layers} are associated with the Mth CSI-RS resource among M reference signal resources. NZ}

[0336] For example, the first CSI-RS resource among M reference signal resources; ...; the Mth CSI-RS resource among M reference signal resources. R The Mth CSI-RS resource among the M reference signal resources can be described as: M R The first CSI-RS resource in the reference signal resources; ...; M R The Mth reference signal resource R One CSI-RS resource; MM R1st CSI-RS resource in the 1st reference signal resource; …; M-th CSI-RS resource in the M-th reference signal resource.

The new table contents obtained by reasonable deformation, supplement or deletion of the contents in table 5 and table 6 all belong to the protection scope of the embodiments of the present application.

[0350] In a possible implementation, the CSI fields corresponding to the M-M R reference signal resources can be arranged by the measurement results of the UE, such as CQI or RSRP, or the arrangement order can be predefined. The embodiments of the present application do not limit this.

[0351] The above Table 1 to Table 6 only take the CSI report #n CSI first part (Part 1) as an example to illustrate the field order of the M channel reference signal resources, and it can be understood that the M channel reference signal resources in the CSI report #n CSI second part (Part 2) wideband, CSI report #n CSI second part (Part 2) subband and other reports multiplex the CSI field order in the CSI report #n CSI first part (Part 1). The specific examples are shown in Table 7 to Table 25.

[0352] The following are examples of the second part of the CSI report of the M channel state information (Table 7 to Table 25).

[0353] In one possible implementation, the above M reference signal resources do not include the reference signal resources configured by the M R access network devices.

[0354] For example, the second part can include wideband CSI (Part 2 wideband CSI) and subband CSI (Part 2 subband CSI), and the second part CSI corresponding to the M reference signal resources is arranged in the order of CRI in the first part CSI, first arranging the wideband CSI of the second part of the channel state information corresponding to the reference signal resource indicated by CRI k0, then arranging the wideband CSI of the second part of the channel state information corresponding to the reference signal resource indicated by CRI k1, and so on. The subband CSI of the second part is arranged in the same way. As shown in Table 7 to Table 8.

[0355] For example, the RI corresponding to one reference signal resource is less than or equal to 4, the wideband CQI of the second TB and the subband CQI of the second TB are not reported; the RI corresponding to one reference signal resource is greater than 4 and less than or equal to 8, the wideband CQI of the second TB and the subband CQI of the second TB are reported.

[0356] For example, one or more items of the wideband CSI field of the second part of the channel state information corresponding to the reference signal resource indicated by at least one CRI are arranged in the following order: the wideband CQI of the second TB, LI, PMI wideband information field X1, PMI wideband information field X2.

[0357] For example, the arrangement of one or more items in the CSI Part2 field corresponding to the M reference signal resources of the CSI report #1 is as follows:

[0358] The first CSI-RS resource in the M reference signal resources is associated with {the wideband CQI of the second TB (if reported), LI, PMI wideband information field X1, PMI wideband information field X2};

[0359] The second CSI-RS resource in the M reference signal resources is associated with {wideband CQI (if reported) of the second TB, LI, PMI wideband information field X1, PMI wideband information field X2};

[0360] ……;

[0361] The Mth CSI-RS resource in the M reference signal resources is associated with {wideband CQI (if reported) of the second TB, LI, PMI wideband information field X1, PMI wideband information field X2}.

[0362] For example, the second part of the channel state information corresponding to the at least one CRI indicated reference signal resource is arranged in the subband CSI field in the following order: all even subband subband differential CQI (if reported) of the second TB, all even subband PMI subband information field X2, all odd subband subband differential CQI (if reported) of the second TB, all odd subband PMI subband information field X2.

[0363] For example, the M reference signal resources corresponding to the CSI Part2 field of the CSI report #1 are arranged in the following order:

[0364] The first CSI-RS resource in the M reference signal resources is associated with {all even subband subband differential CQI (if reported) of the second TB, all even subband PMI subband information field X2, all odd subband subband differential CQI (if reported) of the second TB, all odd subband PMI subband information field X2};

[0365] The second CSI-RS resource in the M reference signal resources is associated with {all even subband subband differential CQI (if reported) of the second TB, all even subband PMI subband information field X2, all odd subband subband differential CQI (if reported) of the second TB, all odd subband PMI subband information field X2};

[0366] ……;

[0367] The Mth CSI-RS resource in the M reference signal resources is associated with {all even subband subband differential CQI (if reported) of the second TB, all even subband PMI subband information field X2, all odd subband subband differential CQI (if reported) of the second TB, all odd subband PMI subband information field X2}.

[0368] For example, if the second part includes wideband CSI (Part 2 wideband CSI) and subband CSI (Part 2 subband CSI), the second part CSI field corresponding to the M reference signal resources can be arranged in the following manner: first, arrange all even subband second part subband CSI fields of all CRIs in the order of the CRIs, and then arrange all odd subband second part subband CSI fields of all CRIs in the order of the CRIs. The arrangement is shown in Table 9 below.

[0369] For example, the CSI Part 2 field corresponding to the M reference signal resources of the CSI report #1 is arranged in one or more of the following manners:

[0370] {subband differential CQI (if reported) of all even subband second TBs, all even subband PMI subband information field X2} associated with the 1st CSI-RS resource in the M reference signal resources;

[0371] {subband differential CQI (if reported) of all even subband second TBs, all even subband PMI subband information field X2} associated with the 2nd CSI-RS resource in the M reference signal resources;

[0372] ……;

[0373] {subband differential CQI (if reported) of all even subband second TBs, all even subband PMI subband information field X2} associated with the Mth CSI-RS resource in the M reference signal resources;

[0374] {subband differential CQI (if reported) of all odd subband second TBs, all odd subband PMI subband information field X2} associated with the 1st CSI-RS resource in the M reference signal resources;

[0375] {subband differential CQI (if reported) of all odd subband second TBs, all odd subband PMI subband information field X2} associated with the 2nd CSI-RS resource in the M reference signal resources;

[0376] ……;

[0421] It should be noted that the above Tables 7-13 are only illustrative examples, and should not be construed as limiting the embodiments of the present application. Any new table content obtained by reasonable modification, supplement or deletion of the content in Tables 7-13 is within the protection scope of the embodiments of the present application.

[0422] In one possible implementation, the M reference signal resources include M R reference signal resources configured by the access network device.

[0423] For example, if the second part (part 2) includes wideband CSI (Part 2 wideband CSI) and subband CSI (Part 2 subband CSI), the second part CSI corresponding to the M reference signal resources is arranged in the order of priority of the M R reference signal resources being higher than the priority of the M-M R reference signal resources. When arranging the wideband CSI, the wideband CSI of the M R reference signal resources is arranged first, and then the wideband CSI of the M-M R reference signal resources is arranged. As shown in Table 14 and Table 15 below. When arranging the subband CSI, the subband CSI of the M R reference signal resources is arranged first, and then the subband CSI of the M-M RThe sub-band CSI of each reference signal resource is shown in Table 16 below.

[0424] It should be noted that when the M reference signal resources include M R When configuring reference signal resources for each access network device, the M R The first part of the CSI corresponding to each reference signal resource is not necessarily ranked in MM. R Before the first part of the CSI corresponding to each reference signal resource, for example, based on M R One reference signal resource and MM R The order of arrangement is determined by at least one of the following parameters corresponding to each reference signal resource: CSI-RS Resource Indicator (CRI), Rank Indicator (RI), Precoding Matrix Indicator (PMI), Channel Quality Indicator (CQI), etc. This application does not limit this.

[0425] For example, the second part may include wideband CSI and subband CSI, and the first part CSI corresponding to the M reference signal resources does not follow the M... R The priority of each reference signal resource is higher than that of MM. R The reference signal resources are arranged in priority order, and the second part of the CSI corresponding to the M reference signal resources is arranged according to the M... R The priority of each reference signal resource is higher than that of MM. R The priority order of the reference signal resources is not limited in the embodiments of this application.

[0426] For example, if the RI corresponding to a reference signal resource is less than or equal to 4, the corresponding second TB broadband CQI and the second TB sub-band CQI are not reported; if the RI corresponding to a reference signal resource is greater than 4 and less than or equal to 8, the corresponding second TB broadband CQI and the second TB sub-band CQI are reported.

[0427] For example, one or more of the wideband CSI fields of part 2 of the channel state information corresponding to at least one CRI-indicated reference signal resource are arranged in the following order: wideband CQI of the second TB (if reported), LI, PMI wideband information field X1, PMI wideband information field X2.

[0428] For example, the CSI Part 2 fields corresponding to the M reference signal resources in CSI report #1 are arranged as follows:

[0429] The first CSI-RS resource associated with the M reference signal resources is {the second TB of broadband CQI (if reported), LI, PMI broadband information field X1, and PMI broadband information field X2}.

[0430] The second CSI-RS resource associated with the M reference signal resources is {the second TB of broadband CQI (if reported), LI, PMI broadband information field X1, and PMI broadband information field X2}.

[0431] ...;

[0432] The Mth reference signal resource R The CSI-RS resource associated with {the second TB of broadband CQI (if reported), LI, PMI broadband information field X1, and PMI broadband information field X2};

[0433] The Mth reference signal resource R +1 CSI-RS resource associated with {the second TB of broadband CQI (if reported), LI, PMI broadband information field X1, PMI broadband information field X2};

[0434] ...;

[0435] The {second TB broadband CQI (if reported), LI, PMI broadband information field X1, PMI broadband information field X2} associated with the Mth CSI-RS resource among the M reference signal resources.

[0436] For example, one or more of the subband CSI fields of part 2 of the channel state information corresponding to at least one CRI-indicated reference signal resource are arranged in the following order: subband differential CQI of all even subband second TB (if reported), subband information field X2 of all even subband PMI, subband differential CQI of all odd subband second TB (if reported), subband information field X2 of all odd subband PMI.

[0437] For example, as shown in Table 16, first arrange the second sub-band CSI field corresponding to the first reference signal resource of M reference signal resources, then arrange the second sub-band CSI field corresponding to the second reference signal resource of M reference signal resources, and so on, until the second sub-band CSI field corresponding to M reference signal resources is arranged.

[0438] For example, one or more of the fields corresponding to the M reference signal resources are shown below:

[0439] The first CSI-RS resource among M reference signal resources is associated with {subband differential CQI (if reported) of the second TB of all even subbands, and the subband information field X2 of PMI of all even subbands, and the subband differential CQI (if reported) of the second TB of all odd subbands, and the subband information field X2 of PMI of all odd subbands}.

[0440] The second CSI-RS resource associated with M reference signal resources is {subband differential CQI of the second TB of all even subbands (if reported), subband information field X2 of all even subbands PMI, subband differential CQI of the second TB of all odd subbands (if reported), subband information field X2 of all odd subbands PMI}.

[0441] ...;

[0443] The Mth reference signal resource R +1 CSI-RS resource associated with {subband differential CQI of the second TB of all even subbands (if reported), all PMI subband information fields of all even subbands x2, subband differential CQI of the second TB of all odd subbands (if reported), all PMI subband information fields of all odd subbands x2};

[0444] ...;

[0445] The Mth CSI-RS resource associated with M reference signal resources is {subband differential CQI (if reported) for the second TB of all even subbands, and the subband information field X2 for the second TB of all even subbands, and the subband differential CQI (if reported) for the second TB of all odd subbands, and the subband information field X2 for the second TB of all odd subbands}.

[0446] For example, as shown in Table 17, first, the CSI fields of the second part of the even-numbered subbands corresponding to the first reference signal resource of the M reference signal resources are arranged. Then, the CSI fields of the second part of the even-numbered subbands corresponding to the second reference signal resource of the M reference signal resources are arranged, and so on. After arranging the fields corresponding to the CSI fields of the second part of the even-numbered subbands of the M reference signal resources, the fields corresponding to the CSI fields of the second part of the odd-numbered subbands corresponding to the M reference signal resources are arranged in sequence.

[0447] For example, one or more of the fields corresponding to the M reference signal resources are shown below:

[0448] The first CSI-RS resource associated with M reference signal resources is {subband differential CQI of all even subbands in the second TB (if reported), and subband information field X2 of all even subbands PMI}.

[0449] The second CSI-RS resource associated with M reference signal resources is {subband differential CQI of all even subbands in the second TB (if reported), and subband PMI information field X2 of all even subbands}.

[0450] ...;

[0451] The Mth reference signal resource R The CSI-RS resource associated with {all even-numbered subband second TB subband differential CQI (if reported), all even-numbered subband PMI subband information field X2};

[0452] The Mth reference signal resource R +1 CSI-RS resource associated with {subband differential CQI of the second TB of all even-numbered subbands (if reported), and PMI subband information fields of all even-numbered subbands x2};

[0453] ...;

[0454] The Mth CSI-RS resource associated with M reference signal resources is {subband differential CQI (if reported) of the second TB of all even subbands, and subband information field X2 of all even subbands PMI}.

[0455] The first CSI-RS resource associated with M reference signal resources is {subband differential CQI of the second TB of all odd-numbered subbands (if reported), and subband information field X2 of all odd-numbered subbands PMI}.

[0456] The second CSI-RS resource associated with M reference signal resources is {subband differential CQI (if reported) of the second TB of all odd-numbered subbands, and subband information field X2 of all odd-numbered subbands PMI}.

[0457] ...;

[0458] The Mth reference signal resource R The CSI-RS resource associated with {all odd-numbered subband second TB subband differential CQI (if reported), all odd-numbered subband PMI subband information field X2};

[0459] The Mth reference signal resource R +1 CSI-RS resource associated with {subband differential CQI (if reported) for the second TB of all odd-numbered subbands, and PMI subband information fields for all odd-numbered subbands x2};

[0460] ...;

[0461] The Mth CSI-RS resource associated with M reference signal resources is {subband differential CQI of the second TB of all odd-numbered subbands (if reported), and subband information field X2 of all odd-numbered subbands PMI}.

[0462] For example, as shown in Table 18, first M R After the second subband CSI field corresponding to the first reference signal resource is sorted out, the second subband CSI field corresponding to the second M reference signal resources is sorted out, and so on, until the M reference signal resources are sorted out. R After sorting the fields corresponding to each reference signal resource, then sort the MM. R After sorting the CSI field of the second part of the even-numbered subband corresponding to the first reference signal resource, sort the MM field. R After the CSI fields of the second part of the even-numbered subband corresponding to the second reference signal resource are sorted, and so on, until all MM are sorted... R After the CSI field of the second part of the even-numbered subband corresponding to each reference signal resource, the MMs are arranged sequentially. R The field corresponding to the CSI of the second part of the odd-numbered subband of each reference signal resource.

[0573] Next, the priority rules of the second part of CSI of the embodiments of the present application are described.

[0574] In one possible implementation, in the second CSI report, the priority of the second field corresponding to M CRIs is higher than the priority of the third field corresponding to at least one CRI.

[0575] In one possible implementation, in the second CSI report, the priority of the group 0 CSI corresponding to M CRIs is higher than the priority of the group 1 CSI or the group 2 CSI corresponding to at least one CRI.

[0576] In the at least one CRI field, the priority of the group 1 CSI is higher than the priority of the group 2 CSI.

[0577] In a possible implementation, in the second CSI report, the priority of the fifth field corresponding to at least one of the CRIs is higher than the priority of the sixth field corresponding to at least one of the CRIs, where the fifth field includes even subband fields in the third field or group 1 CSI in the fourth field, the sixth field includes odd subband fields in the third field or group 2 CSI in the fourth field, the even subband field includes subband differential CQI of all even subband second TBs and / or all even subband PMI subband information field X2, and the odd subband field includes subband differential CQI of all odd subband second TBs and / or all odd subband PMI subband information field X2.

[0578] In the present application, the number of priority indexes of the second part of CSI is related to the value of the M and / or the M R .

[0579] For example, the number of priority indexes of the second part of subband CSI corresponding to at least one of the M CRIs is 2; or, the number of priority indexes of the second part of subband CSI corresponding to at least one of the M CRIs is 1.

[0580] In a possible implementation, the CSI report on PUSCH includes two parts, and the UE can omit the second part of CSI. The omission of the second part of CSI is in the priority order shown in Table 26 below, where N Rep is the number of CSI reports configured to be carried on PUSCH. Priority 0 is the highest priority, and priority 2N Rep is the lowest priority. CSI report n corresponds to the CSI report with the n-th smallest value of Pri i,CSI (y, k, c, s) defined in 3GPP TS 38.214 5.2.5. The subbands of a given CSI report n indicated by the higher layer parameter csi-ReportingBand with a value of "1" are numbered consecutively in increasing order, and the lowest subband of csi-ReportingBand with a value of "1" is subband 0. When the second part of CSI information of a certain priority is omitted, the UE should omit all information of that priority.

[0581] For example, for CSI report #1-CSI report #N RepIn one or more reports, Group 0 CSI (Group 0 CSI for CSI reports) or Part 2 wideband CSI (Part 2 wideband CSI for CSI reports) has the highest priority, with a priority value of 0. For CSI report #1, the priority value of Group 1 CSI (Group 1 CSI for CSI) or Part 2 subband CSI of even subbands for CSI is 1; the priority value of Group 2 CSI (Group 2 CSI for CSI) or Part 2 subband CSI of odd subbands for CSI is 2; for CSI report #2, the priority value of Group 1 CSI (Group 1 CSI) or Part 2 subband CSI of even subbands for CSI is 3; the priority value of Group 2 CSI (Group 2 CSI) or Part 2 subband CSI of odd subbands for CSI is 4, and so on. For CSI report #N... Rep The priority value of the second part of the CSI in group 1 or even-numbered subbands is 2N. Rep -1, where the priority value of the second part of the CSI in group 2 or odd-numbered subbands is 2N. Rep As shown in Table 26 below.

[0582] For example, the priority of group 0 CSI / group 1 CSI / group 2 CSI applies to the type II codebook, such as 'typeII-r16', 'typeII-PortSelection-r16', 'typeII-PortSelection-r17', 'typeII-Doppler-r18' or 'typeII-Doppler-PortSelection-r18', 'typeII-r19', 'typeII-PortSelection-r19', 'typeII-PortSelection-r19', 'typeII-Doppler-r19' or 'typeII-Doppler-PortSelection-r19'. This application embodiment does not limit this.

[0583] For example, the priority of the second subband CSI (even subband CSI / odd subband CSI) applies to the typeI codebook, or typeI-r19. This application embodiment does not limit this.

[0584] Table 26

[0585] In one possible implementation, the CSI reporting on PUSCH includes two parts, and the UE can omit the second part CSI. The omission of the 2nd part CSI follows the priority order shown in Table 27 below, where N Rep is the number of CSI reports configured to be carried on PUSCH. Priority 0 is the highest priority, and priority 2MN Rep is the lowest priority, and CSI report n corresponds to the CSI report with the value of Pri i,CSI (y, k, c, s) of the n-th smallest CSI report as defined in 3GPP TS 38.214 Section 5.2.5. The subbands of a given CSI report n indicated by the higher layer parameter csi-ReportingBand with the value of “1” are consecutively numbered in increasing order, and the lowest subband of csi-ReportingBand with the value of “1” is subband 0. When the 2nd part CSI information of a certain priority is omitted, the UE shall omit all information of that priority.

[0586] For example, for CSI report #1 - CSI report #N Rep , the priority of Group 0 CSI or Part 2 wideband CSI in one or more reports is the highest priority, and the value of the priority is 0. The value of the priority corresponding to the last field of CSI report #n-1 is pn, and for CSI report #n:

[0587] The value of the priority of Group 1 CSI or Part 2 subband CSI of even subbands for CSI associated with the 1st resource of the M reference signal resources is pn+1;

[0588] The value of the priority of Group 2 CSI or Part 2 subband CSI of odd subbands for CSI associated with the 1st resource of the M reference signal resources is pn+2;

[0593] For example, the priority of the Group 0 CSI / Group 1 CSI / Group 2 CSI is applicable to the typeII codebook, for example, 'typeII-r16', 'typeII-PortSelection-r16', 'typeII-PortSelection-r17', 'typeII-Doppler-r18' or 'typeII-Doppler-PortSelection-r18', 'typeII-r19', 'typeII-PortSelection-r19', 'typeII-PortSelection-r19', 'typeII-Doppler-r19' or 'typeII-Doppler-PortSelection-r19', which is not limited by the embodiments of the present application.

[0596] In one possible implementation, the CSI reporting on PUSCH includes two parts, and the UE can omit the second part of CSI. The omission of the second part of CSI is in the priority order shown in Table 28 below, where N Repis the number of CSI reports configured to be carried on the PUSCH. The priority 0 is the highest priority, and the priority of the CSI report n corresponds to the priority pn of the CSI report defined in the subclause 5.2.5 of 3GPP TS 38.214. The priority of the CSI report n is determined by the following rules: i,CSI The (y, k, c, s) value of the nth-smallest CSI report. The subbands of a given CSI report n indicated by the higher layer parameter csi-ReportingBand with the value of "1" are numbered consecutively in increasing order, with the lowest subband of csi-ReportingBand with the value set to "1" as subband 0. When the second part of CSI information of a certain priority is omitted, the UE shall omit all information of that priority.

[0597] For example, for CSI report #1 - CSI report #N Rep The priority of the Group 0 CSI or the Part 2 wideband CSI for the one or more reports is the highest priority, with the value of the priority being 0. The last field of the CSI report #n-1 corresponds to the priority with the value of pn, and for the CSI report #n:

[0598] The priority of the Group 1 CSI or the Part 2 subband CSI of even subbands for the CSI associated with the 1st resource of the M reference signal resources has the value of pn+1;

[0605] The priority value of the Group 2 CSI (Group 2 CSI for CSI) or Part 2 subband CSI of odd subbands associated with the Mth resource among M reference signal resources is pn+2M. See Table 28 below.

[0606] For example, the priority of group 0 CSI / group 1 CSI / group 2 CSI applies to the type II codebook, such as 'typeII-r16', 'typeII-PortSelection-r16', 'typeII-PortSelection-r17', 'typeII-Doppler-r18' or 'typeII-Doppler-PortSelection-r18', 'typeII-r19', 'typeII-PortSelection-r19', 'typeII-PortSelection-r19', 'typeII-Doppler-r19' or 'typeII-Doppler-PortSelection-r19'.

Priority 0 is the highest priority, and CSI report n corresponds to the Principal level in the CSI report defined in section 5.2.5 of 3GPP TS 38.214. i,CSI The (y,k,c,s) value represents the nth smallest CSI report. Subbands of a given CSI report n, indicated by the higher-layer parameter csi-ReportingBand with a value of "1", are numbered sequentially in ascending order, with the lowest subband of the csi-ReportingBand set to "1" designated as subband 0. When the second part of the CSI information for a specific priority is omitted, the UE should omit all information for that priority.

[0683] It should be understood that the priority rules of the second part CSI shown in the above table are only exemplary, and the priority rules of the second part CSI in the embodiments of the present application are not limited.

[0684] In one possible implementation, for CSI report #1-CSI report #N Rep The priority of the group 0 CSI (Group 0 CSI for CSI reports) or the second part wideband CSI (Part 2 wideband CSI for CSI reports) in one or more reports is the highest priority, and the value of the priority is 0.

[0687] For example, the above M' can be 1, M R , The minimum value of the three, or the maximum value of the three, or the minimum value or the maximum value between two of them, without limitation.

[0688] When the second part of the CSI information of a certain priority is omitted, the UE should omit or discard the part of the information of the priority in the following way:

[0689] Method one: then according to the Group 1 CSI (Group 1 CSI for CSI) and Group 2 CSI (Group 2 CSI for CSI) or the Part 2 subband CSI of even subbands for CSI report and the Part 2 subband CSI of odd subbands for CSI corresponding to a single reference signal resource to omit.

[0690] For example, the field corresponding to the Mth reference signal resource is omitted first, and then the field corresponding to the M-1th reference signal resource is omitted, and so on.

[0691] According to a single reference signal resource, first omit the corresponding Group 2 CSI (Group 2 CSI for CSI) and the second part of subband CSI (Part 2 subband CSI of odd subbands for CSI) of odd subbands, and then omit the corresponding Group 1 CSI (Group 1 CSI for CSI) or the second part of subband CSI (Part 2 subband CSI of even subbands for CSI) of even subbands, and so on.

[0692] For example, first omit the Group 2 CSI (Group 2 CSI for CSI) and the second part of subband CSI (Part 2 subband CSI of odd subbands for CSI) of odd subbands corresponding to the Mth resource in M resources, and then omit the Group 1 CSI (Group 1 CSI for CSI) or the second part of subband CSI (Part 2 subband CSI of even subbands for CSI) of even subbands corresponding to the Mth resource in M resources, first omit the Group 2 CSI (Group 2 CSI for CSI) and the second part of subband CSI (Part 2 subband CSI of odd subbands for CSI) of odd subbands corresponding to the M-1th resource in M resources, and then omit the Group 1 CSI (Group 1 CSI for CSI) or the second part of subband CSI (Part 2 subband CSI of even subbands for CSI) of even subbands corresponding to the M-1th resource in M resources, and so on.

[0693] Method two: according to the Group 1 CSI (Group 1 CSI for CSI) or the second part of subband CSI (Part 2 subband CSI of even subbands for CSI) of even subbands, or the Group 2 CSI (Group 2 CSI for CSI) and the second part of subband CSI (Part 2 subband CSI of odd subbands for CSI) of odd subbands corresponding to M R R ​Group 1 CSI for CSI corresponding to the reference signal resource or Part 2 subband CSI of even subbands for CSI, or Group 2 CSI for CSI and Part 2 subband CSI of odd subbands for CSI corresponding to the reference signal resource are omitted.

[0694] For example, Group 1 CSI for CSI corresponding to the reference signal resource or Part 2 subband CSI of even subbands for CSI are omitted first. R For example, Group 2 CSI for CSI and Part 2 subband CSI of odd subbands for CSI corresponding to the reference signal resource are omitted first. R For example, Group 1 CSI for CSI corresponding to the reference signal resource or Part 2 subband CSI of even subbands for CSI are omitted first. R For example, Group 2 CSI for CSI and Part 2 subband CSI of odd subbands for CSI corresponding to the reference signal resource are omitted first. R For example, Group 1 CSI for CSI corresponding to the reference signal resource or Part 2 subband CSI of even subbands for CSI are omitted first.

[0695] For example, Group 1 CSI for CSI corresponding to the reference signal resource or Part 2 subband CSI of even subbands for CSI are omitted first.

[0696] The above manners do not affect the scope of protection of the present application.

[0697] For example, the priority of Group 0 CSI / Group 1 CSI / Group 2 CSI is applicable to typeII codebook, for example, 'typeII-r16', 'typeII-PortSelection-r16', 'typeII-PortSelection-r17', 'typeII-Doppler-r18' or 'typeII-Doppler-PortSelection-r18', 'typeII-r19', 'typeII-PortSelection-r19', 'typeII-PortSelection-r19', 'typeII-Doppler-r19' or 'typeII-Doppler-PortSelection-r19', and the present embodiment is not limited in this regard.

[0698] For example, the priority of the second part of subband CSI (even subband CSI / odd subband CSI) is applicable to typeI codebook, or typeI-r19, and the present embodiment is not limited in this regard.

[0700] It can be understood that the value pn of the priority described above can also be understood as the priority corresponding to the last one or more fields of the CSI report #n-1; or the value pn of the priority described above can also be understood as the priority corresponding to the field corresponding to the last one or more resources of the CSI report #n-1.

[0701] Next, the mapping order of the CSI report to the UCI bit sequence of the present embodiment is described.

[0702] For example, for the first part of CSI, the mapping rule can be according to the following Table 34.

[0703] Table 34

[0704] For example, if any CSI is transmitted on the PUSCH with priority index 0, the following UCI bit sequence is generated: (if any) and (if any) is according to the following:

[0709] For example, for a CSI#i report containing fields corresponding to M resources, the CSI part 2 of the M resources are mapped to the corresponding segments of the UCI bit sequence of the CSI report #i in descending order of the M CRIs.

[0713] Table 37

[0714] For example, let As a bit sequence of CSI part 2, if CSI part 2 is also transmitted on PUSCH, at least one of the CSI fields reported by CSI, in descending order of importance in Table 37, is matched by... Initial UCI bit sequence

[0715] For example, for a CSI#i report containing fields corresponding to M resources, the CSI part 2 of the M resources is mapped to the corresponding segments of the UCI bit sequence of CSI report #i in descending order of the M CRIs. This includes the CSI part 2 wideband of CSI report #1 or group 0 of CSI part 2, ..., the CSI part 2 wideband of CSI report #n or group 0 of CSI part 2, the CSI part 2 subband corresponding to the first resource of the M resources in CSI report #1 or groups 1 and 2 of CSI part 2, the CSI part 2 subband corresponding to the second resource of the M resources in CSI report #1 or groups 1 and 2 of CSI part 2, ..., the Mth resource of the M resources in CSI report #1...

[0717] For example, let As a bit sequence of CSI part 2, if CSI part 2 is also transmitted on PUSCH, at least one of the CSI fields reported by CSI, in descending order of the order in Table 38, is matched by... Initial UCI bit sequence

[0718] For example, for a CSI#i report containing M resource corresponding fields, the CSI part 2 of the M resources are mapped to the corresponding segments of the UCI bit sequence of the CSI report#i in the order of the M CRIs from high to low. The CSI part 2 wideband or group 0 of the CSI part 2 of the 1st resource of the M resources of the CSI report#1, the CSI part 2 even subband or group 1 of the CSI part 2 of the 1st resource of the M resources of the CSI report#1, the CSI part 2 odd subband or group 2 of the CSI part 2 of the 1st resource of the M resources of the CSI report#1, the CSI part 2 subband or group 1 and group 2 of the 2nd resource of the M resources of the CSI report#1, the CSI part 2 subband or group 1 and group 2 of the Mth resource of the M resources of the CSI report#1, the CSI part 2 even subband or group 1 of the 1st resource of the M resources of the CSI report#n, the CSI part 2 odd subband or group 2 of the 1st resource of the M resources of the CSI report#n, the CSI part 2 subband or group 1 and group 2 of the 2nd resource of the M resources of the CSI report#n, the CSI part 2 subband or group 1 and group 2 of the Mth resource of the M resources of the CSI report#n, and so on. R R R R R R ​​​​​The CSI part 2 subband or group 1 and group 2 corresponding to the Mth resource of the M resources of the CSI report #i.

[0719] Table 39

[0720] For example, let As the bit sequence of the CSI part 2, if the CSI part 2 is also transmitted on the PUSCH, the CSI fields of at least one CSI report are matched to the corresponding segments of the UCI bit sequence of the CSI report #i in the order from high to low in Table 39. The UCI bit sequence starting from

[0721] For example, for a CSI #i report containing M resource corresponding fields, the CSI part 2 of the M resources is mapped to the corresponding segment of the UCI bit sequence of the CSI report #i in the order from high to low of the M CRIs. The CSI part 2 wideband or group 0 of the CSI report #1,..., the CSI part 2 wideband or group 0 of the CSI report #n; the CSI part 2 even subband or group 1 of the M resources corresponding to the CSI report #1, the CSI part 2 odd subband or group 2 of the M resources corresponding to the CSI report #1,..., the CSI part 2 even subband or group 1 of the M resources corresponding to the CSI report #n, the CSI part 2 odd subband or group 2 of the M resources corresponding to the CSI report #n.

[0722] Based on the above technical solutions, the receiving end can report multiple measurement reports when reporting the measurement report, or can carry the channel state information corresponding to multiple reference signals in the same measurement report, and sort the CSI fields in the above manner. When the uplink transmission resource is limited, the fields with relatively low priority can be discarded according to the above CSI field priority, to ensure the transmission performance.

[0723] In the present application, for how to report multiple sets of CSI measurement results for one CSI information, there may be some fields in the multiple sets of CSI measurement results that are invalid. For example, there may be a wideband CQI of some pilot resources that is invalid, in which case other fields associated with the pilot resources (such as subband CQI, PMI, LI, etc.) will be normally reported, and the normal reporting of the invalid fields increases the CSI reporting overhead.

[0724] Therefore, the present application proposes that when multiple sets of CSI measurement results are reported for one CSI information, if the wideband CQI of some pilot resources is invalid, then the other fields associated with the pilot resources can not be reported, thereby avoiding the reporting of invalid CSI.

[0725] In one possible implementation, the wideband CQI field of a first TB corresponding to N reference signal resources in M reference signal resources is invalid, and the second CSI report does not include one or more fields corresponding to the N reference signal resources other than the wideband CQI field of the first TB, N being an integer less than M.

[0726] In the second CSI report, the one or more fields corresponding to the N reference signal resources other than the wideband CQI field of the first TB can be understood as not reporting the one or more fields corresponding to the N reference signal resources other than the wideband CQI field of the first TB.

[0727] It should be understood that the wideband CQI field of the first TB corresponding to the reference signal resources is invalid, which can be understood as CQI out of range. The CQI out of range can be that the first CQI is lower than or exceeds a preset threshold. For example, when the channel quality is poor, the CQI value is lower than the set threshold, that is, it is considered to be out of range.

[0728] It should be understood that when the value of the wideband CQI of the first TB of a certain reference signal resource is out of range, the other part of the field corresponding thereto cannot be normally calculated, for example, the subband CQI, PMI, LI, etc. corresponding thereto cannot be calculated. In other words, even if the other part of the field corresponding thereto is normally reported, it is also an invalid field, which occupies a certain bit.

[0729] Next, the one or more fields corresponding to the N reference signal resources other than the wideband CQI field of the first TB are described.

[0730] For example, the one or more fields belong to the first part of CSI described above, and the one or more fields include at least one of the following fields:

[0731] Rank indication RI, subband differential CQI of the first TB, and indication K of the sum of all layer non-zero coefficientsNZ .

[0732] For example, the one or more fields belong to the second part of CSI as described above, and the one or more fields include at least one of the following fields:

[0733] wideband CQI, layer indication LI, PMI wideband information field X1, PMI wideband information field X2, subband differential CQI of all even subbands second TB, subband differential CQI of all odd subbands second TB, PMI subband information field X2 of all even subbands, PMI subband information field X2 of all odd subbands, group 0 CSI, group 1 CSI and group 2 CSI of the second TB.

[0734] Next, the way of not reporting one or more fields of the first TB except the wideband CQI field corresponding to the N reference signal resources is described.

[0735] In a possible implementation, the one or more fields of the first TB except the wideband CQI field corresponding to the N reference signal resources belong to the first part of CSI as described above, and the one or more fields are set to zero or filled with the eighth field.

[0736] For example, the format of the first part of CSI is shown in Table 40 and Table 41.

[0737] Table 40

[0738] In Table 40, it is assumed that M is equal to 4, and the CRI field is used to carry the reference signal resource index value, CRI k0-CRI k3 are used to indicate that 4 channel state information resource indexes are reported. At least one CRI field corresponds to the reference signal resource associated with the channel state information. It is assumed that the wideband CQI of the first TB of the second reference signal resource corresponding to CRI k1 and the fourth reference signal resource corresponding to CRI k3 is invalid, and the subband differential CQI in the first TB of the second reference signal resource and the fourth reference signal resource is not reported, and the field can be set to zero or filled with the eighth field.

[0739] Table 41

[0740] In Table 41 above, it is assumed that M is equal to 4, the CRI field is used to carry the reference signal resource index value, CRI k0-CRI k3 are used to indicate 4 channel state information resource indexes to be reported. At least one CRI field corresponds to a reference signal resource associated with the channel state information. Assuming that the wideband CQI of the first TB of the second reference signal resource corresponding to CRI k1 and the fourth reference signal resource corresponding to CRI k3 is invalid, the subband differential CQI in the first TB of the second reference signal resource and the fourth reference signal resource and the indicator K of the sum of non-zero coefficients of all layers are not reported, and the two fields can be set to zero or filled in the eighth field. NZ Not reported, and the two fields can be set to zero or filled in the eighth field.

[0741] It should be noted that the above Table 40 and Table 41 are only exemplary descriptions, for example, the number of M is only exemplary description, and should not be limited to the embodiments of the present application. The new table content obtained by reasonable deformation, supplement or deletion of the content in Table 40 and Table 41 belongs to the protection scope of the embodiments of the present application.

[0742] It should be noted that the above-mentioned manner is also applicable to any format of the first part of CSI, for example, Tables 1-6 in the foregoing, which is not limited by the embodiments of the present application.

[0743] In another possible implementation, the one or more fields corresponding to the N reference signal resources except the wideband CQI field of the first TB belong to the second part of CSI described in the foregoing, and the one or more fields are discarded.

[0744] Exemplarily, the format of the second part of CSI is shown in Table 42 and Table 43.

[0745] Table 42

[0752] It should be noted that the above method is also applicable to any format of the second part of CSI, such as Tables 7-25 mentioned above. This application embodiment does not limit this.

[0754] In one possible implementation, in the M R In the first resource, the broadband CQI field of the first TB corresponding to X first resources is invalid, and the M R - The fields corresponding to the X first resources are preceding the fields corresponding to the X first resources, and the X first resources are some or all of the N reference signal resources.

[0755] In the M-M RN-M second resources correspond to the second field of the first TB of the N-M second resources. R The (N-X) second resources correspond to the field before the field of the N-X second resources.

[0764] Optionally, when the eighth field is filled and there is still a spare position, the spare position can be set to zero.

[0765] Exemplarily, the format of the first partial CSI is shown in Table 45.

[0766] Table 45

[0767] As shown in Table 45, assuming that M is equal to 4, the CRI field is used to carry a reference signal resource index value, and CRI k0-CRI k3 are used to indicate 4 channel state information resource indexes to be reported. At least one CRI field corresponds to a reference signal resource associated with a channel state information. Assuming that the wideband CQI of the first TB of the second reference signal resource corresponding to CRI k1 and the fourth reference signal resource corresponding to CRI k3 is invalid, the subband differential CQI in the first TB of the second reference signal resource is not reported, and the field can be filled with the wideband field of the second partial CSI associated with the first resource. Similarly, the subband differential CQI in the first TB of the fourth reference signal resource is not reported, and the field can be filled with the wideband field of the second partial CSI associated with the third resource.

[0768] It should be noted that Table 45 is only an exemplary description, for example, the number of M is only an exemplary description, and should not be limited to the embodiments of the present application. The new table content obtained by reasonable deformation, supplement or deletion of the content in Table 45 belongs to the protection scope of the embodiments of the present application.

[0769] Optionally, when all the second partial CSI wideband fields of the M-N reference signal resources are filled, the positions of all the second partial CSI wideband fields of the M-N reference signal resources can be filled with the second partial CSI subband fields corresponding to part or all of the M-N reference signal resources.

[0770] For example, the eighth field can include part or all of the second partial CSI wideband field corresponding to part or all of the M-N reference signal resources and part or all of the second partial CSI subband field. For example, the eighth field can include at least one of the following corresponding to part or all of the M-N reference signal resources: the wideband CQI of the second TB, the layer indication LI, the PMI wideband information field X1, the PMI wideband information field X2, the subband differential CQI of the second TB of all even subbands, the subband differential CQI of the second TB of all odd subbands, the PMI subband information field X2 of all even subbands, and the PMI subband information field X2 of all odd subbands.

For example, the eighth field can include at least one of the following corresponding to part or all of the M-N reference signal resources: group 0 CSI, group 1 CSI, and group 2 CSI.

[0773] It should be understood that when there are still empty positions after filling the eighth field, zeros can be filled.

[0774] For example, the eighth field can include at least one of the fields corresponding to the M R X first resources in the second partial CSI. That is, in the M R first resources, the wideband CQI field of the first TB corresponding to the X first resources is invalid, and the X first resources can be filled in other fields of the first partial CSI excluding the wideband CQI field of the first TB. R X first resources in the second partial CSI. That is, in the M R first resources, the wideband CQI field of the first TB corresponding to the N-X second resources is invalid, and the N-X second resources can also be filled in the same way.

[0775] For example, the eighth field can include at least one of the fields corresponding to the M R X first resources in the second partial CSI. That is, in the M RX first resources in the M first resources correspond to the first TB whose wideband CQI field is invalid, then the X first resources can fill M-M R -(N-X) second resources in the M first resources correspond to the first TB whose wideband CQI field is invalid, and the same way can be used for filling. R

[0776] For example, the eighth field can include at least one of the fields corresponding to the M R -X first resources in the second part of CSI and at least one of the fields corresponding to the M-M R -(N-X) second resources in the second part of CSI. That is, in the M R X first resources in the M first resources correspond to the first TB whose wideband CQI field is invalid, then the X first resources can fill M R -X first resources in the second part of CSI and M-M R -(N-X) second resources in the second part of CSI. That is, in the M R X first resources in the M first resources correspond to the first TB whose wideband CQI field is invalid, and the same way can be used for filling.

[0777] In an optional implementation, the eighth field includes at least one of the fields corresponding to the M R -X first resources in the second part of CSI and at least one of the fields corresponding to the M-M R -(N-X) second resources in the second part of CSI, the M R -X first resources correspond to the fields in the M-M R -(N-X) second resources correspond to the fields. That is, when filling the second part of CSI of the high-priority resource and the ordinary resource (ordinary beam) whose wideband CQI field of the first TB is not invalid, the second part of CSI of the high-priority resource can be filled first.​

[0778] It should be noted that the eighth field is only illustrative, and in actual application, the eighth field can be CSI information of a beam with higher priority or higher importance, and the embodiments of the present application are not limited in this regard.

[0779] In a possible implementation, the terminal device can send first indication information, where the first indication information is used to indicate the eighth field.

[0780] For example, the first indication information can be used to indicate a reference signal resource.

[0781] For example, the first indication information can be used to indicate a specific CSI field corresponding to the reference signal resource.

[0782] In a possible implementation, the eighth field is a predefined field.

[0783] For example, a field index can be predefined.

[0784] For example, a padding relationship can be predefined.

[0785] For example, a plurality of groups of CSI fields and a relationship between the groups that are padded to each other can be predefined. For example, the groups that are padded to each other are defined by an index of the group.

[0786] Based on the above technical solutions, if the wideband CQI of the first TB of a part of reference signal resources is invalid when the terminal device reports the measurement report, at least one field associated with the reference signal in other fields can not be reported, thereby avoiding reporting of invalid CSI. In addition, the field position that is not reported can be mapped to a related field of other resources. In this way, when the reported resources are limited or conflicted, the CSI information of an important beam can be preferentially protected.

[0787] In the present application, a plurality of possible formats of channel state information fields reported by a terminal device are shown, and the embodiments of the present application are not limited in this regard.
