In other examples, a helicopter or unmanned aerial vehicle can be configured to act as a device that communicates with another base station.

[0090] In some deployments, the network device mentioned in the 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.

[0091] 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) (also known as a 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.

[0092] In some deployments, the CU is a logical node that hosts the 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 connects with network nodes such as a core network over some interfaces, which can be an E2 interface or the like. Optionally, the CU has some functionality of the core network. The CU (e.g., PDCP layer and higher) connects with the DU (e.g., radio link control (RLC) layer and lower) over some interfaces, which can be an Fl interface or the like. 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, in some examples, signaling procedures for the Fl. The Fl interface supports a control plane (Fl control plane, Fl-C), a user plane (Fl user plane, Fl-U).

[0093] 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 configuration of the CU and the DU is merely an example, and the CU and the DU can be configured to 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.

[0094] In some deployments, the DU is a logical node that carries the RLC layer, the MAC layer, the higher physical layer (Higher PHY layer), and other functions. In some examples, the DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be front-haul interfaces. 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] First, a communication system suitable for the embodiments of the present application is briefly introduced as follows.

[0103] FIG. 1 is a schematic diagram of a wireless communication system suitable for the embodiments of the present application.

[0104] As shown in FIG. 1, the wireless communication system includes a radio access network 100. The radio access network 100 can be a radio access network in a future communication network, or a traditional (for example, 5G, 4G, 3G or 2G) radio access network. One or more terminal devices (120a-120j, collectively referred to as 120) can be connected to each other or connected to one or more network devices (110a, 110b, collectively referred to as 110) in the radio access network 100. The network elements in the wireless communication system are connected through interfaces (for example, NG, Xn), or air interfaces.

[0105] FIG. 1 is only a schematic diagram, and the wireless communication system can further include other devices, such as a core network (CN) device, a wireless relay device, and / or a wireless backhaul device, which are not shown in FIG. 1.

[0106] FIG. 2 is another schematic diagram of a wireless communication system suitable for embodiments of the present application.

For example, a BBU in the access network device communicates with the core network through a backhaul, 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, and the BBU and the RU can be co-located or not. 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.

[0108] FIG. 2 is only a schematic diagram, and the wireless communication system can further include other devices, which are not shown in FIG. 2.

[0109] In order to facilitate better understanding of the technical solutions of the present application, some related technologies involved in the technical solutions of the present application are introduced.

[0110] 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.

[0111] 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).

[0112] A transmit beam can refer to a distribution of signal strength in different directions in space after a signal is transmitted by an antenna, and a receive beam can refer to a distribution of signal strength in different directions in space for a wireless signal received by an antenna.

[0113] In addition, a beam can be a wide beam, or a narrow beam, or another type of beam. Techniques for forming a beam can be beamforming techniques or other techniques. Beamforming techniques can be digital beamforming techniques, analog beamforming techniques, or hybrid digital / analog beamforming techniques, etc.

[0114] One beam can correspond to one or more antenna ports, which can be used to transmit data channels, control channels, sounding signals, etc. One or more antenna ports corresponding to one beam can also be regarded as one antenna port set.

[0115] In this application, a beam can be replaced by a spatial filter, a spatial filter, a spatial parameter, a spatial parameter, a spatial setting, a spatial setting, quasi-co-location (QCL) information, QCL assumption, QCL indication, transmission configuration indication (TCI) state (TCI-state or TCI state), spatial relationship, etc. The above terms are also equivalent to each other. The beam can also be replaced by other terms representing the beam, which is not limited in this application.

[0116] 2. Reference signal (RS): can also be called pilot, reference sequence, reference signal, etc. For the sake of unity, the reference signal is described below. The reference signal can be used for measurement, such as channel measurement or channel estimation, etc.

[0117] The channel measurement involved in this application also includes beam measurement, that is, obtaining beam quality information 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 referred to as signal-to-interference ratio). In the embodiments of the application, for the convenience of description, unless otherwise specified, the channel measurement involved can be regarded as beam measurement.

[0118] In this application, the reference signal can be, for example, any one of the following: channel state information reference signal (CSI-RS), synchronization signal block (SSB), sounding reference signal (SRS), user equipment specific reference signal (US-RS), demodulation reference signal (DMRS), phase tracking reference signal (PT-RS), cell reference signal (CRS), etc. It should be understood that the above-mentioned reference signals are only examples and should not constitute any limitation on this application. This application does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

[0119] 3. Reference signal resource: can be used to configure the transmission attributes of the reference signal, such as time-frequency resource location, port mapping relationship, power factor, and scrambling code, etc. The transmitting end device can transmit the reference signal based on the reference signal resource, and the receiving end device can receive the reference signal based on the reference signal resource.

[0120] In order to distinguish different reference signal resources, each reference signal resource can correspond to a reference signal resource identifier (or reference signal resource index, or reference signal resource indicator), such as CSI-RS resource identifier or CSI-RS resource index or indicator (CRI), SSB resource identifier or SSB resource index or indicator (SSBRI), SRS resource identifier or SRS resource index or indicator (SRI).

[0121] In the embodiments of this 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 the reference signal received based on the reference signal resource, or the signal quality measured based on the reference signal resource received and measured.

[0122] 4. Channel information: indicates information that can reflect the characteristics and quality of the channel.

[0123] As an example, the channel information is at least one of: channel state information (CSI), channel time-varying information, or channel frequency offset information, etc. Hereinafter, the channel information is mainly 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.

[0124] Taking the network side obtaining downlink CSI through the terminal device for 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.

[0125] As an example, the CSI includes at least one of: channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), 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.

[0126] Using more spectrum resources is an important means to improve the capacity of wireless channels, and higher frequency bands will be used in future communication networks. Because the higher the frequency band, the greater the signal energy transmission loss under the same transmission distance. In order to overcome this problem, a larger antenna array is usually used on the network device side to weight 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 the HBF architecture, that is, one digital channel drives multiple antenna elements through multiple phase shifters, and the network device side downlink signal transmission usually adopts two-level weights in the analog and digital domains.

[0127] FIG. 3 is a schematic diagram of a network device side HBF architecture. As shown in FIG. 3, under the HBF architecture, the network device usually adopts multiple analog beams to implement coverage of different areas in the cell, and different analog beams cover different terminal devices. Considering the mid-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, in order to enable simultaneous transmission of multiple terminal devices in the cell under resource multiplexing, the terminal device can measure the channel state information under multiple analog beams, thereby providing input for data scheduling decision of the network device.

[0128] Specifically, the configuration for channel state information reporting contains one or more reference signal resource sets, each reference signal resource set contains one or more reference signal resources, and each 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 to report the channel state information to the network device side. Through the CRI reporting value, the network device is informed of the 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.

[0129] However, considering real-time services in the network and scheduling requirements of terminal devices, the set of terminal devices to be scheduled in the network at different times, and the amount of services to be scheduled for each terminal device are dynamically variable, and the set of analog beams to be measured by each terminal device can be different.

[0130] FIG. 4 is a schematic diagram of a terminal device to be scheduled. As shown in (a) of FIG. 4, when only UE1 and UE2 have services to be scheduled at this time (such as T1 time), UE2 can preferentially measure beam 1 and beam 2; as shown in (b) of FIG. 4, when only UE2, UE3 and UE4 have services to be scheduled at this time (such as T2 time), UE2 can preferentially measure beam 2 and beam 3.

[0131] However, based on the existing protocol, the network device can configure multiple reference signal resources for channel state information measurement for the terminal device, that is, different analog beams can be configured as different reference signal resources, and the terminal device autonomously decides to report channel state information of which reference signal resource. At this time, since the terminal device cannot perceive the to-be-scheduled information of other terminal devices in the cell, the selected reported analog beams are generally based on channel quality to select the corresponding top P to report, and the value of P can depend on the measurement capability of the terminal device.

[0132] Therefore, the present application proposes that the network device side can indicate the priority information of the reference signal resource to the terminal device according to the actual communication situation, such as real-time business in the existing network and scheduling requirements of the terminal device, so that the terminal device can perform measurement and reporting based on the priority information of the reference signal resource, and realize the network device side assisting (or guiding) the terminal device to select one or more appropriate channel state information for reporting.

[0133] Before introducing the scheme of the present application, the following points are explained.

[0134] (1) In the present application, "indication" can include direct indication, indirect indication, display indication, and implicit indication. When describing that a 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.

[0135] 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 the index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, wherein the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be only indicated a part, 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, the 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 in multiple sub-information, and the sending period and / or sending time of these sub-information can be the same or different.

[0136] (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, such as between network devices and terminal devices, or can be carried out within a device, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0137] (3) In various embodiments of the present application, the terms and / or descriptions of different embodiments are consistent and can be referred to each other if there is no special description and logical conflict, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0138] (4) In the present application, "first", "second", and "#1", "#2", "#n1", "#n2", etc. are only for convenience of description and are used to distinguish objects, and are not used to 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 schemes other than the embodiments of the present application.

[0139] (5) In the present application, "predefined" can mean standard protocol predefined, or can also mean pre-agreed or pre-negotiated between devices.

[0140] (6) In the present application, words such as "exemplarily" and "such as" 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 use of the word "example" is intended 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, and it should be pointed out that when their differences are not emphasized, the meanings they express are consistent.

[0141] The method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments provided by the present application can be applied to the communication system shown in FIG. 1, without limitation.

[0142] In the following embodiments, terminal devices and network devices are exemplarily described. The terminal devices can be replaced by components (e.g., chips or chip systems or circuits) of the terminal devices, and the network devices can be replaced by components (e.g., chips or chip systems or circuits) of the network devices.

[0143] FIG. 5 is a schematic diagram of a communication method 500 according to an embodiment of the present application. The method 500 shown in FIG. 5 can include the following steps.

[0144] 501. The terminal device receives first indication information, and the network device sends the first indication information accordingly.

[0145] The first indication information indicates one or more of the following: whether the Ks reference signal resources include a high-priority reference signal resource, the number M of high-priority reference signal resources, and the M high-priority reference signal resources. S R R

[0146] Ks is an integer greater than or equal to 1, and M is an integer greater than or equal to 0. S R

[0147] The high-priority reference signal resource in the embodiments of the present application can represent a reference signal resource that the network device expects the terminal device to measure preferentially or report measurement results (e.g., CSI) preferentially.

[0148] Optionally, the first indication information is carried in the following signaling: RRC, MAC CE, or DCI.

[0149] The first indication information is carried in the signaling and the specific indication manner of the first indication information will be described in detail later.

[0150] It should be understood that the reference signal resource referred to in the embodiments of the present application can represent a reference signal resource for measurement, such as a reference signal resource for measurement configured by the network device. The measurement can be channel measurement, or referred to as beam measurement. In the following embodiments, channel measurement is used for description for the sake of description and distinction.

[0151] 502. The terminal device receives reference signals through the Ks reference signal resources.

[0152] Optionally, the Ks reference signal resources include the M high-priority reference signal resources indicated by the first indication information. R

[0153] Optionally, the Ks reference signal resources further include non-high-priority reference signal resources.

[0154] ​​​​​​In the embodiments of the present application, the non-high-priority reference signal resource refers to a reference signal resource other than the high-priority reference signal resource. For example, part of the Ks reference signal resources are high-priority reference signal resources, and the remaining reference signal resources are non-high-priority reference signal resources.

[0155] The terminal device can perform receiving measurement on the corresponding reference signal resource based on the reference signal resource (i.e., the Ks reference signal resources) configured by the network device, in other words, the terminal device receives the reference signal on the Ks reference signal resources and performs measurement. In step 502, the terminal device can receive multiple reference signals.

[0156] 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. For another example, the reference signal is an SSB, and correspondingly, the reference signal resource is an SSB resource.

[0157] 503, the terminal device obtains M channel state information.

[0158] Specifically, the terminal device performs measurement (such as channel measurement) based on one or more reference signal resources in the Ks reference signal resources, thereby obtaining the M channel state information.

[0159] M is an integer greater than 1 or equal to 1.

[0160] Optionally, the M channel state information includes channel state information of at least one high-priority reference signal resource. In other words, the terminal device obtains the channel state information of at least one high-priority reference signal resource by performing measurement on at least one reference signal resource in the M R high-priority reference signal resources.

[0161] Optionally, the M channel state information includes M R channel state information. In other words, the terminal device obtains the M R channel state information by performing measurement on the M R high-priority reference signal resources.

[0162] Optionally, the M channel state information further includes channel state information obtained by performing measurement on a non-high-priority reference signal resource in the Ks reference signal resources.

[0163] It can be understood that one channel state information can also include measurement results corresponding to multiple reference signal resources, or measurement results corresponding to one reference signal resource can be in multiple channel state information, which is not limited. In the following embodiments, for ease of illustration, one channel state information corresponding to one reference signal resource is mainly taken as an example for illustration.

[0164] In addition, one channel state information can also be referred to as one piece of channel state information. The channel state information can also be referred to as any one of the following: report, measurement report, or CSI report. For the channel state information, refer to the related description in the previous term explanation part, which is not repeated here.

[0165] 504, the terminal device sends M channel state information. Correspondingly, the network device receives the M channel state information.

[0166] As an example, the M channel state information can be carried in at least one of the following: physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH).

[0167] Further optionally, the method 500 further includes: the terminal device receives configuration information, and the configuration information is configuration information for reporting the channel state information. Wherein, K S reference signal resources are carried in the configuration information, and the K S reference signal resources include high-priority reference signal resources and / or non-high-priority reference signal resources.

[0168] In the embodiments of the present application, the configuration information and the first indication information can be carried in one signaling, or can also be carried in different signaling, which is not limited.

[0169] In a possible implementation, the network device sends RRC signaling to the terminal device, and configures one or more CSI reporting configurations (CSI-ReportConfig) for the terminal device through the RRC signaling. Each CSI-ReportConfig is associated with one or more reference signal resource sets (such as a CSI-RS resource set (csi-rs-resourceSet)), and each reference signal resource set contains one or more reference signal resources that can be used for channel measurement and / or interference measurement. The reference signal resource can be at least one of the following: a NZP CSI-RS resource (non-zero power CSI-RS resource), a zero power (ZP) CSI-RS resource (ZP CSI-RS resource), a CSI interference measurement resource (CSI-IM resource), or an SSB resource.

[0170] Optionally, the CSI-ReportConfig described above can also be CSI-associated reporting configuration information (CSI-AssociatedReportConfigInfo). That is, in the embodiments of the present application, the channel state information reporting can refer to the CSI-ReportConfig, or can refer to the CSI-AssociatedReportConfigInfo, which is not limited.

[0171] The embodiments of the present application will be described below in combination with several aspects. It can be understood that the contents of the following aspects can be used alone or in combination, and the embodiments of the present application do not limit this.

[0172] Aspect 1: a related scheme in which the first indication information is carried in signaling.

[0173] In the embodiments of the present application, the specific form of the first indication information is not limited, so that the terminal device can confirm the number of high-priority reference signal resources and the high-priority reference signal resources through the first indication information.

[0174] Optionally, the first indication information is a field in one of the following information elements: an information element of CSI-ReportConfig, an information element of CSI-AssociatedReportConfigInfo, an information element of NZP-CSI-RS-ResourceSet, and an information element of NZP-CSI-RS-Resource.

[0175] In the first indication information is a newly defined field, or the first indication information is obtained by modifying a field in an original information element, which is not limited in the embodiments of the present application.

[0176] The embodiments of the present application do not limit the information element to which the first indication information belongs, and the following describes several possible implementation manners.

[0177] Scheme #1: The first indication information is carried in RRC signaling.

[0178] (1) The first indication information is carried in an information element of CSI-ReportConfig.

[0179] For example, the network device sends RRC signaling to the terminal device, configures one or more CSI-ReportConfig for the terminal device through the RRC signaling, and adds the first indication information in an information element of any CSI-ReportConfig.

[0180] For example, the first indication information is a field, for example, a field called highPriorityCRI, which indicates M high-priority reference signal resources through the highPriorityCRI. R When the first indication information is added as a new field in the information element of CSI-ReportConfig, a specific example is as follows.

[0181] It can be seen that the information element of CSI-ReportConfig adds the first indication information highPriorityCRI to indicate M high-priority reference signal resources. R The specific indication manner of highPriorityCRI will be described in detail later. It should be understood that the use of highPriorityCRI to indicate M high-priority reference signal resources is only an exemplary description, and the embodiments of the present application do not limit the specific form and name of the first indication information. R The use of highPriorityCRI to indicate M high-priority reference signal resources is only an exemplary description, and the embodiments of the present application do not limit the specific form and name of the first indication information.

[0182] Another example, the first indication information is a certain field, for example, called highPriorityFlag, through highPriorityFlag to indicate whether the K S reference signal resources include high priority reference signal resources. When the first indication information is added as a new field in the information element of CSI-ReportConfig, the specific example is as follows.

[0183] It can be seen that the first indication information highPriorityFlag is added in the information element of CSI-ReportConfig to indicate whether the K S reference signal resources include high priority reference signal resources. The specific indication method of highPriorityFlag will be described in detail later. It should be understood that highPriorityFlag is only an example description, and the specific form and name of the first indication information are not limited by the embodiments of the present application.

[0184] Another example, the first indication information is a certain field, for example, called M R , through M R to indicate the number M R of high priority reference signal resources. When the first indication information is added as a new field in the information element of CSI-ReportConfig, the specific example is as follows.

[0185] It can be seen that the first indication information M R is added in the information element of CSI-ReportConfig to indicate the number M R of high priority reference signal resources. The specific indication method of the first indication information to indicate the number M R of high priority reference signal resources will be described in detail later. It should be understood that M R is only an example description, and the specific form and name of the first indication information are not limited by the embodiments of the present application.

[0186] For example, the network device sends RRC signaling to the terminal device, through which the terminal device is configured with one or more CSI-ReportConfig, a first indication information is added in the information element of any one of the CSI-ReportConfig (denoted as CSI-ReportConfig#A), and the association between CSI-ReportConfig#A and another CSI-ReportConfig (denoted as CSI-ReportConfig#B or associatedCSI-ReporeConfig) is established. In this way, the first indication information in CSI-ReportConfig#A indicates the number and the high-priority reference signal resource, and the other parameter information (such as reportConfigType, reportQuantity, etc.) in CSI-ReportConfig#A is multiplexed with the content in CSI-ReportConfig#B. In this way, the content to be indicated by CSI-ReportConfig#A is reduced.

[0187] For example, the first indication information is a field, for example, highPriorityCRI, which indicates M R high-priority reference signal resources. When the first indication information is added as a new field in the information element of the CSI-ReportConfig, the specific example is as follows.

[0188] It can be seen that the first indication information highPriorityCRI is added in the information element of the CSI-ReportConfig to indicate M R high-priority reference signal resources. It should be understood that the use of highPriorityCRI to indicate M R high-priority reference signal resources is only an example description, and the specific form and name of the first indication information are not limited in the embodiments of the present application.

[0189] (2) The first indication information is carried in the information element of the CSI-AssociatedReportConfigInfo.

[0190] For example, the network device sends RRC signaling to the terminal device, through which one or more CSI-AssociatedReportConfigInfo is configured to the terminal device, and a first indication information is added in the information element of any one of the CSI-AssociatedReportConfigInfo.

[0191] For example, the first indication information is a field, for example, called highPriorityFlag, through which it is indicated whether the K S high priority reference signal resources are included in the K S reference signal resources. When the first indication information is added as a new field in the information element of the CSI-AssociatedReportConfigInfo, a specific example is as follows.

[0192] It can be seen that the first indication information highPriorityFlag is added in the information element of the CSI-AssociatedReportConfigInfo to indicate whether the K S high priority reference signal resources are included in the K R reference signal resources. The specific indication method of highPriorityFlag will be described in detail later. It should be understood that highPriorityFlag is only an example description, and the specific form and name of the first indication information are not limited by the embodiments of the present application.

[0193] It should be understood that in some possible implementations, the above-mentioned first indication information highPriorityFlag can also be a first indication information for indicating the number M R of high priority reference signal resources, or a first indication information for indicating M R high priority reference signal resources, which is not limited.

[0194] (3) The first indication information is carried in the information element of NZP-CSI-RS-ResourceSet.

[0195] For example, the first indication information is added in the information element of the NZP-CSI-RS-ResourceSet associated with the CSI-ReportConfig. The NZP-CSI-RS-ResourceSet is used for channel measurement.

[0196] For example, the first indication information is a field, for example, called highPriorityFlag, through which it is indicated whether the K Swhether the K reference signal resources include high priority reference signal resources. When the first indication information is added as a new field in the information element of NZP-CSI-RS-ResourceSet, a specific example is as follows.

[0197] It can be seen that the first indication information highPriorityFlag is added in the information element of NZP-CSI-RS-ResourceSet to indicate whether the K S reference signal resources include high priority reference signal resources. The specific indication manner of highPriorityFlag will be described in detail later. It should be understood that highPriorityFlag is only an exemplary description, and the specific form and name of the first indication information are not limited in the embodiments of the present application.

[0198] It should be understood that in some possible implementation manners, the above-mentioned first indication information highPriorityFlag can also be the first indication information for indicating the number M R of high priority reference signal resources, or the first indication information for indicating M R high priority reference signal resources, which is not limited.

[0199] (4) The first indication information is carried in the information element of NZP-CSI-RS-Resource.

[0200] For example, the NZP-CSI-RS-ResourceSet associated with the CSI-ReportConfig includes one or more NZP-CSI-RS-Resources, and the first indication information is added in the information element of any NZP-CSI-RS-Resource.

[0201] For example, the first indication information is a certain field, for example, called high priority reference signal resource identifier (highPriorityCRIFlag), which indicates whether the corresponding NZP-CSI-RS-Resource is a high priority reference signal resource through highPriorityCRIFlag. When the first indication information is added as a new field in the information element of NZP-CSI-RS-Resource, a specific example is as follows.

[0202] It can be seen that the first indication information highPriorityCRIFlag is added in the information element of the NZP-CSI-RS-Resource to indicate whether the corresponding NZP-CSI-RS-Resource is a high priority reference signal resource. It should be understood that the highPriorityCRIFlag is only described as an example, and the specific form and name of the first indication information are not limited in the embodiments of the present application.

[0203] It should be understood that the above-mentioned first indication information highPriorityCRIFlag can also be information element for indicating the number M R of high priority reference signal resources, or information element for indicating M R high priority reference signal resources, which is not limited.

[0204] Scheme #2, the first indication information is carried in the DCI signaling.

[0205] It should be understood that the network device indicates the terminal device to perform CSI reporting in a non-fixed time interval through the DCI signaling. Therefore, the first indication information is added in the DCI signaling to indicate one or more of the following: whether the K S reference signal resources include high priority reference signal resources, the number M R of high priority reference signal resources, and M R high priority reference signal resources.

[0206] For example, the first indication information is carried in the CSI request field.

[0207] In a possible implementation, the CSI request includes N bits, wherein N1 bits are used to indicate the network device triggered aperiodic channel state information reporting, and N2 bits are used to indicate the high priority reference signal resources associated with the aperiodic channel state information reporting.

[0208] Wherein N, N1, and N2 are positive integers, and N1+N2=N.

[0209] The above-mentioned aspect 1 is mainly described by taking RRC / DCI as an example, and the embodiments of the present application are not limited thereto. For example, the first indication information can also be carried in other signaling, or the first indication information is added in the information element in other signaling.

[0210] Aspect 2, specific indication manner of the first indication information.

[0211] Scheme #1, the first indication information indicates whether the K S reference signal resources include high priority reference signal resources.

[0212] The embodiment of the present application does not limit the specific manner of the first indication information indicating whether the K S reference signal resources include the high-priority reference signal resource.

[0213] For example, the first indication information is a certain field, for example, called highPriorityFlag, which indicates whether the K S reference signal resources include the high-priority reference signal resource through the highPriorityFlag.

[0214] It should be understood that the highPriorityFlag is only an example, and the embodiment of the present application does not limit the specific form and name of the first indication information.

[0215] When the highPriorityFlag takes the value true, it represents that the K S reference signal resources include the high-priority reference signal resource. In this case, the terminal device can determine the high-priority reference signal resource in the K S reference signal resources in combination with the first criterion. In other words, the first indication information indirectly indicates the M R high-priority reference signal resources.

[0216] When the highPriorityFlag takes the value false, it represents that the K S reference signal resources do not include the high-priority reference signal resource. In this case, the terminal device decides which channel state information of the reference signal resources to report by itself.

[0217] The first criterion is one or more of the following:

[0218] (1) The number M R of the high-priority reference signal resources is predefined by a protocol.

[0219] (2) In the case where the K S reference signal resources are sorted according to a sorting criterion, the first M R reference signal resources after sorting are the high-priority reference signal resources.

[0220] The method in the embodiment of the present application does not limit the source of the first criterion. For example, the first criterion is configured by a network device or predefined by a protocol.

[0221] It can be understood that the "sorting criterion" is only a naming for convenience of description, and the naming does not limit the protection scope of the embodiment of the present application. For example, the "sorting criterion" can be replaced by "scheme" or "criterion" or "condition", etc. For another example, the "sorting criterion" can be replaced by the specific content of the criterion.

[0222] The method in the embodiments of the present application is not limited to a specific sorting criterion, so that the first M S of the K R reference signal resources after sorting are high-priority reference signal resources.

[0223] Method (1): The K S reference signal resources are sorted in ascending order of CRI, and the first M R reference signal resources are high-priority reference signal resources, and the other (K S -M R ) reference signal resources are non-high-priority reference signal resources.

[0224] Method (2): The K S reference signal resources are sorted in descending order of CRI, and the first M R reference signal resources are high-priority reference signal resources, and the other (K S -M R ) reference signal resources are non-high-priority reference signal resources.

[0225] Method (3): The K S reference signal resources are sorted in ascending order of NZP-CSI-RS-ResourceId, and the first M R reference signal resources are high-priority reference signal resources, and the other (K S -M R ) reference signal resources are non-high-priority reference signal resources.

[0226] Method (4): The K S reference signal resources are sorted in descending order of NZP-CSI-RS-ResourceId, and the first M R reference signal resources are high-priority reference signal resources, and the other (K S -M R ) reference signal resources are non-high-priority reference signal resources.

[0227] For example, when K S = 4, that is, the information element "NZP-CSI-RS-Resources" of a reference signal resource set indicates K S{NZP-CSI-RS-ResourceId = n1, NZP-CSI-RS-ResourceId = n2, NZP-CSI-RS-ResourceId = n3, NZP-CSI-RS-ResourceId = n4}.

[0228] wherein n1, n2, n3, n4 are reference signal resource identifiers, and optionally, the reference signal resource identifiers are ordered according to their values, for example, n2 < n4 < n1 < n3.

[0229] For example, K S reference signal resources are ordered according to their indices or indicators from small to large, i.e., when K S = 4, the information element "NZP-CSI-RS-Resources" of one reference signal resource set indicates K S reference signal resource indices or indicators, as shown in Table 1, each reference signal resource includes an index or indicator corresponding thereto, and the reference signal resources are ordered according to their indices or indicators from small to large.

[0230] The reference signal resource index or indicator 0 represents the first reference signal resource in the information element "NZP-CSI-RS-Resources", i.e., the reference signal resource corresponding to NZP-CSI-RS-ResourceId = n1 has the index or indicator 0; the reference signal resource index or indicator 1 represents the second reference signal resource in the information element "NZP-CSI-RS-Resources", i.e., the reference signal resource corresponding to NZP-CSI-RS-ResourceId = n2 has the index or indicator 1; the reference signal resource index or indicator 2 represents the third reference signal resource in the information element "NZP-CSI-RS-Resources", i.e., the reference signal resource corresponding to NZP-CSI-RS-ResourceId = n3 has the index or indicator 2; and the reference signal resource index or indicator 3 represents the fourth reference signal resource in the information element "NZP-CSI-RS-Resources", i.e., the reference signal resource corresponding to NZP-CSI-RS-ResourceId = n4 has the index or indicator 3.

[0231] Table 1

[0232] When the highPriorityFlag has the value true, the terminal device determines, in combination with the first criterion, a high-priority reference signal resource from the K S reference signal resources.

[0233] An example, the ranking criterion in the above manner (1), with reference to Table 1, when M R = 1, indicates that the reference signal resource NZP-CSI-RS-ResourceId = n1 corresponding to index or indicator 0 is a high priority reference signal resource; M R = 2, indicates that the reference signal resource NZP-CSI-RS-ResourceId = n1 corresponding to index or indicator 0 and the reference signal resource NZP-CSI-RS-ResourceId = n2 corresponding to index or indicator 1 are high priority reference signal resources; and so on.

[0234] Another example, the ranking criterion in the above manner (3), i.e., according to the value of the identification of the reference signal resource, for example n2 < n4 < n1 < n3, when M R = 1, indicates that the reference signal resource NZP-CSI-RS-ResourceId = n2 is a high priority reference signal resource; M R = 2, indicates that the reference signal resources NZP-CSI-RS-ResourceId = n2 and NZP-CSI-RS-ResourceId = n4 are high priority reference signal resources; and so on.

[0235] Scheme #2, the first indication information indicates the number M R of high priority reference signal resources.

[0236] When the first indication information indicates the number M R of high priority reference signal resources, the terminal device determines the M R high priority reference signal resources based on the association relationship between the number M R of high priority reference signal resources and the M R high priority reference signal resources. In other words, the first indication information indirectly indicates the M R high priority reference signal resources.

[0237] Embodiments of the present application do not limit the association relationship between the number M R of high priority reference signal resources and the M R high priority reference signal resources, for example, the association relationship can be configured by a network device or predefined by a protocol.

[0238] An example, the association relationship between the number M R of high priority reference signal resources and the M R high priority reference signal resources is that, in the case of K S reference signal resources sorted according to the ranking criterion, the first M RThe K

[0239] The ordering criterion can refer to the foregoing content, and will not be described again.

[0240] For example, when K S = 4, the K S reference signal resources are ordered according to the values of the reference signal resource identifiers, for example, n2 < n4 < n1 < n3, that is, the information element “NZP-CSI-RS-Resources” of one reference signal resource set indicates K S reference signal resource identifiers, respectively, {NZP-CSI-RS-ResourceId = n1, NZP-CSI-RS-ResourceId = n2, NZP-CSI-RS-ResourceId = n3, NZP-CSI-RS-ResourceId = n4}.

[0241] For example, when the first indication information indicates that M R = 0, it means that the K S reference signal resources do not include high-priority reference signal resources; when the first indication information indicates that M R = 1, it means that the reference signal resource with NZP-CSI-RS-ResourceId = n2 is a high-priority reference signal resource; when the first indication information indicates that M R = 2, it means that the reference signal resource with NZP-CSI-RS-ResourceId = n2 and the reference signal resource with NZP-CSI-RS-ResourceId = n4 are high-priority reference signal resources, and the like.

[0242] For example, when K S = 4, the K S reference signal resources are ordered from small to large according to the reference signal resource indexes or indicators, as shown in Table 1.

[0243] For example, when the first indication information indicates that M R = 0, it means that the K S reference signal resources do not include high-priority reference signal resources; when the first indication information indicates that M R = 1, it means that the reference signal resource corresponding to the index or indicator 0 is a high-priority reference signal resource; when the first indication information indicates that M R = 2, it means that the reference signal resource corresponding to the index or indicator 0 and the reference signal resource corresponding to the index or indicator 1 are high-priority reference signal resources, and the like.

[0244] For example, when the first indication information indicates that M Ra number of high priority reference signal resources.

[0245] In a first possible implementation, the first indication information directly indicates the number M R of high priority reference signal resources.

[0246] Optionally, the first indication information indicates M R high priority reference signal resource indexes or indicators.

[0247] Optionally, the first indication information indicates an identity of M R high priority reference signal resources.

[0248] Optionally, the first indication information indicates that K S reference signal resources do not include high priority reference signal resources.

[0249] In this case, the terminal device can determine the number M R of high priority reference signal resources according to the high priority reference signal resources indicated by the first indication information, i.e., without explicitly indicating the number M R of high priority reference signal resources; or the number M R of high priority reference signal resources is predefined by a protocol, and is not limited.

[0250] Optionally, the number M R of high priority reference signal resources has a correlation relationship with a number of bits occupied by M R high priority reference signal resource indexes or indicators, specifically one or more of the following:

[0251] First correlation relationship: the number of bits occupied by M R high priority reference signal resource indexes or indicators = X*the number M R of high priority reference signal resources, where X is a number of bits occupied by information bits of each reference signal resource index, and X is an integer greater than or equal to 1.

[0252] Second correlation relationship: the number of bits occupied by M R high priority reference signal resource indexes or indicators = X*the number M R of high priority reference signal resources + 1.

[0253] In a first implementation, the first indication information indicates M R high priority reference signal resource indexes or indicators, and the number M R of high priority reference signal resources is predefined by a protocol or indicated by other information, and is not limited. The following gives an exemplary description.

[0254] Example 1: Assuming KS = 4, the reference signal resources are {NZP-CSI-RS-ResourceId = n1, NZP-CSI-RS-ResourceId = n2, NZP-CSI-RS-ResourceId = n3, NZP-CSI-RS-ResourceId = n4}; assuming that the information bits of each reference signal resource index or indicator occupy X = 2 bits, when the first association relationship is adopted, M R = 1 represents that the first indication information occupies 2 bits.

[0255] Specifically, when M R = 1, the correspondence between the value of the first indication information and the high-priority reference signal resource is, for example, as shown in Table 2:

[0256] Table 2

[0257] As shown in Table 2, when X = 2, M R = 1, the first indication information indicates 1 high-priority reference signal resource index or indicator, and the first indication information occupies 2 bits. When the first indication information takes "00", the terminal device can determine, based on the first indication information and Table 2, that NZP-CSI-RS-ResourceId = n1 is a high-priority reference signal resource. When the first indication information takes "01", the terminal device can determine, based on the first indication information and Table 2, that NZP-CSI-RS-ResourceId = n2 is a high-priority reference signal resource, and so on.

[0258] Example 2: Assuming that K S = 4, the reference signal resources are {NZP-CSI-RS-ResourceId = n1, NZP-CSI-RS-ResourceId = n2, NZP-CSI-RS-ResourceId = n3, NZP-CSI-RS-ResourceId = n4}; assuming that the information bits of each reference signal resource index or indicator occupy X = 2 bits, when the first association relationship is adopted, M R = 2 represents that the first indication information occupies 2*2 = 4 bits.

[0259] Specifically, when M R = 2, the correspondence between the value of the first indication information and the high-priority reference signal resource is, for example, as shown in Table 3:

[0260] Table 3

[0261] As shown in Table 3, when X = 2, M RWhen K = 2, the first indication information indicates 2 high priority reference signal resource indexes or indicators, the first indication information occupies 4 bits, and each 2 bits indicates 1 high priority reference signal resource index or indicator. When the first indication information takes "0001", the terminal device can determine NZP-CSI-RS-ResourceId = n1 and NZP-CSI-RS-ResourceId = n2 as high priority reference signal resources based on the first indication information and Table 3; when the first indication information takes "0010", the terminal device can determine NZP-CSI-RS-ResourceId = n1 and NZP-CSI-RS-ResourceId = n3 as high priority reference signal resources based on the first indication information and Table 3, and so on.

[0262] Mode two: the first indication information indicates the number M of high priority reference signal resources R and M R high priority reference signal resources.

[0263] Example 1: assuming K S = 4, the reference signal resources are {NZP-CSI-RS-ResourceId = n1, NZP-CSI-RS-ResourceId = n2, NZP-CSI-RS-ResourceId = n3, NZP-CSI-RS-ResourceId = n4}. The protocol predefines the available value list of M R , for example, the available value list of M R is {0, 1}, and M R = 0 represents that the K S reference signal resources do not include high priority reference signal resources, and M R = 1 represents that the K S reference signal resources include 1 high priority reference signal resource.

[0264] Based on the available value list of M R , the first indication information is all 0 bits representing that the K S reference signal resources do not include high priority reference signal resources, and the first indication information is non-all 0 bits representing that the K S reference signal resources include 1 high priority reference signal resource.

[0265] As shown in Table 4, the first indication information indicates the number M R of high priority reference signal resources and M R high priority reference signal resources, the first indication information occupies 3 bits, and the value of the first indication information and the corresponding relationship of the high priority reference signal resources are, for example, Table 4.

[0266] It should be understood that when K S = 4 and M R = 1, the first indication information occupies 2 bits to indicate the corresponding high priority reference signal resource index or indicator (assuming that each reference signal index or indicator occupies 2 bits of information bits), since the number of high priority reference signal resources M R is indicated by all 0 bits and non-all 0 bits, and the number of high priority reference signal resources M R = 1 is indicated by all 0 bits.

[0267] Table 4

[0268] In one aspect, as shown in Table 4, the terminal device can determine the number M R of high priority reference signal resources according to the value of the first indication information. Specifically, when the first indication information is all 0 bits (the value of the first indication information is "000"), the terminal device can determine that there is no high priority reference signal resource in the K S reference signal resources; when the first indication information is non-all 0 bits (the value of the first indication information is "001" or "010" or "011" or "100"), the terminal device can determine that there is 1 high priority reference signal resource in the K S reference signal resources.

[0269] In another aspect, as shown in Table 4, the terminal device can determine M R high priority reference signal resources according to the value of the first indication information. When the value of the first indication information is "001", the terminal device can determine that NZP-CSI-RS-ResourceId = n1 is a high priority reference signal resource according to the first indication information and Table 4; when the value of the first indication information is "010", the terminal device can determine that NZP-CSI-RS-ResourceId = n2 is a high priority reference signal resource according to the first indication information and Table 4, and so on.

[0270] Example 2: Assuming that K S = 6, the reference signal resources are {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}. The protocol predefines the value list of M R , for example, the value list of M R is {0, 1}, and the value of M R is 0, which represents that K S = 6.The reference signal resources do not include high-priority reference signal resources, M. R A value of 1 represents K S Each reference signal resource includes one high-priority reference signal resource.

[0271] Based on M R The possible value list is {0, 1}, and the first indication information is all 0 bits representing K. S The reference signal resources do not include high-priority reference signal resources, and the first indication information is a non-all-zero bit representation of K. S Each reference signal resource includes one high-priority reference signal resource.

[0272] As shown in Table 5, the first indication information also indicates the number M of high-priority reference signal resources. R With M R Each high-priority reference signal resource occupies 3 bits of the first indication information, and the correspondence between the value of the first indication information and the high-priority reference signal resource is shown in Table 5.

[0273] Table 5

[0274] On the one hand, as shown in Table 5, the terminal device can determine the number M of high-priority reference signal resources based on the value of the first indication information. R Specifically, when the first indication information is all 0 bits (the first indication information takes the value "000"), the terminal device can determine K. S The reference signal resources do not include high-priority reference signal resources; when the first indication information is not all zero bits (the first indication information takes the value of "001" or "010" or "011" or "100" or "101" or "110"), the terminal device can determine K. S Each reference signal resource includes one high-priority reference signal resource.

[0275] On the other hand, as shown in Table 5, the terminal device can determine M based on the value of the first instruction information. R There are several high-priority reference signal resources. When the first indication information is "001", the terminal device can determine that NZP-CSI-RS-ResourceId=n1 is a high-priority reference signal resource based on the first indication information and Table 5; when the first indication information is "010", the terminal device can determine that NZP-CSI-RS-ResourceId=n2 is a high-priority reference signal resource based on the first indication information and Table 5, and so on.

[0276] In the second possible implementation, the first indication information is a bitmap, and the first indication information indicates M. R A high-priority reference signal resource.

[0277] Specifically, the first indication information is a bitmap, and each bit in the bitmap corresponds to one of the K S reference signal resources, and a first value of the bit represents that the reference signal resource is a high priority reference signal resource, and a second value of the bit represents that the reference signal resource is a non-high priority reference signal resource. The first value is 1, and the second value is 0, or the first value is 0, and the second value is 1.

[0278] In this case, the terminal device can determine the number M R of high priority reference signal resources according to the number of first values, i.e., without the need for additional explicit indication of the number M R of high priority reference signal resources.

[0279] Optionally, the correspondence between the bits in the bitmap and the reference signal resources can include one or more of the following:

[0280] Correspondence one: low bits correspond to reference signal resources with smaller reference signal resource indexes or indicators, and high bits correspond to reference signal resources with larger reference signal resource indexes or indicators.

[0281] Correspondence two: low bits correspond to reference signal resources with larger reference signal resource indexes or indicators, and high bits correspond to reference signal resources with smaller reference signal resource indexes or indicators.

[0282] Correspondence three: low bits correspond to reference signal resources with smaller reference signal resource identifiers, and high bits correspond to reference signal resources with larger reference signal resource identifiers.

[0283] Correspondence four: low bits correspond to reference signal resources with larger reference signal resource identifiers, and high bits correspond to reference signal resources with smaller reference signal resource identifiers.

[0284] For example, based on the value of the first field bitmap, the terminal device can determine the number M R of high priority reference signal resources and M R high priority reference signal resources at the same time.

[0285] For example, it is assumed that K SWhen the bitmap is equal to 4, the reference signal resources are {NZP-CSI-RS-ResourceId=n1, NZP-CSI-RS-ResourceId=n2, NZP-CSI-RS-ResourceId=n3, NZP-CSI-RS-ResourceId=n4}, the reference signal resources are ordered according to the reference signal resource indexes or indicators, NZP-CSI-RS-ResourceId=n1 is the first reference signal resource, NZP-CSI-RS-ResourceId=n2 is the second reference signal resource, NZP-CSI-RS-ResourceId=n3 is the third reference signal resource, and NZP-CSI-RS-ResourceId=n4 is the fourth reference signal resource. When the correspondence between the bit and the reference signal resource is the correspondence one, the correspondence between the value of the first field bitmap and the high priority reference signal resource is, for example, shown in Table 6.

[0286] Table 6

[0287] For example, as shown in Table 6, each bit of the value of the first indication information bitmap indicates whether the reference signal resource corresponding to the bit is a high priority reference signal resource, wherein the low bit corresponds to the reference signal resource with a smaller reference signal resource index or indicator, and the high bit corresponds to the reference signal resource with a larger reference signal resource index or indicator. The first value "1" of the bit represents that the reference signal resource corresponding to the bit is a high priority reference signal resource, and the second value "0" of the bit represents that the reference signal resource corresponding to the bit is a non-high priority reference signal resource.

[0288] That is, the first indication information bitmap is "0000", and the terminal device can determine that none of the K S reference signal resources is a high priority reference signal resource according to the first indication information; the first indication information bitmap is "0001", and the terminal device can determine that the first reference signal resource NZP-CSI-RS-ResourceId=n1 is a high priority reference signal resource according to the first indication information; the first indication information bitmap is "0010", and the terminal device can determine that the second reference signal resource NZP-CSI-RS-ResourceId=n2 is a high priority reference signal resource according to the first indication information, and so on.

[0289] The terminal device can determine the number M R of high priority reference signal resources according to the number of first values "1" included in the first indication information bitmap.

[0290] In a third possible implementation, the first indication information indicates whether each of the K reference signal resources is a high priority reference signal resource. S

[0291] For example, the first indication information includes K S fields, each of which corresponds to each of the K S reference signal resources. When a reference signal resource is a high priority reference signal resource, the field corresponding to the reference signal resource takes a first value, and when the reference signal resource is a non-high priority reference signal resource, the field corresponding to the reference signal resource takes a second value. The first value and the second value are different, for example, the first value is true or yes, and the second value is false or no.

[0292] In this case, the terminal device can determine the number M R of high priority reference signal resources according to the number of first values, i.e., without explicitly indicating the number M R of high priority reference signal resources.

[0293] Optionally, the correspondence between each of the K S fields and the reference signal resources can include one or more of the following:

[0294] Correspondence one: the field with a smaller field index or indicator corresponds to the reference signal resource with a smaller reference signal resource index or indicator, and the field with a larger field index or indicator corresponds to the reference signal resource with a larger reference signal resource index or indicator.

[0295] Correspondence two: the field with a smaller field index or indicator corresponds to the reference signal resource with a larger reference signal resource index or indicator, and the field with a larger field index or indicator corresponds to the reference signal resource with a smaller reference signal resource index or indicator.

[0296] Correspondence three: the field with a smaller field index or indicator corresponds to the reference signal resource with a smaller reference signal resource identifier, and the field with a larger field index or indicator corresponds to the reference signal resource with a larger reference signal resource identifier.

[0297] Correspondence four: the field with a smaller field index or indicator corresponds to the reference signal resource with a larger reference signal resource identifier, and the field with a larger field index or indicator corresponds to the reference signal resource with a smaller reference signal resource identifier.

[0298] Here, the field index or indicator refers to the position of each field in the K S fields.

[0299] For example, when K S ​= 2, i.e., the first indication information includes two fields, for example, {true, false}, where the field index or indicator of true is, for example, 0, representing that the field is arranged in the first position, and the field index or indicator of false is, for example, 1, representing that the field is arranged in the second position.

[0300] In a fourth possible implementation, the first indication information includes a first field, and the terminal device determines M R high-priority reference signal resources according to a value of the first field.

[0301] Optionally, a number of bits occupied by the first field is related to values of K S and M R , and satisfies formula (1).

[0302] wherein, represents rounding up.

[0303] In Example 1, the terminal device determines positions of M R high-priority reference signal resources in K S reference signal resources according to a value of the first field.

[0304] For example, when M R = 1 and K S = 4, the number of bits occupied by the first field is 2. That is, the first field uses 2 bits to indicate positions of M R high-priority reference signal resources in K S reference signal resources.

[0305] Suppose K S = 4, the reference signal resources are {NZP-CSI-RS-ResourceId = n1, NZP-CSI-RS-ResourceId = n2, NZP-CSI-RS-ResourceId = n3, NZP-CSI-RS-ResourceId = n4}.

[0306] Optionally, when the first field is "00", it indicates that the reference signal resource NZP-CSI-RS-ResourceId=n1 in the first position is a high priority reference signal resource; when the first field is "01", it indicates that the reference signal resource NZP-CSI-RS-ResourceId=n2 in the second position is a high priority reference signal resource; when the first field is "10", it indicates that the reference signal resource NZP-CSI-RS-ResourceId=n3 in the third position is a high priority reference signal resource; and when the first field is "11", it indicates that the reference signal resource NZP-CSI-RS-ResourceId=n4 in the fourth position is a high priority reference signal resource.

[0307] It should be understood that the number of bits occupied by the first field is determined according to formula (1) for the purpose of saving signaling resources. In other possible implementations, the first field can occupy more bits, which is not limited.

[0308] For example, when M R = 1, K S = 4, the number of bits occupied by the first field is 3. That is, when the first field is "000", it indicates that the reference signal resource NZP-CSI-RS-ResourceId=n1 in the first position is a high priority reference signal resource; when the first field is "001", it indicates that the reference signal resource NZP-CSI-RS-ResourceId=n2 in the second position is a high priority reference signal resource, and so on.

[0309] In example 2, the terminal device determines the reference signal resource group to which the M R high priority reference signal resources belong according to the value of the first field, and determines the M R high priority reference signal resources according to the reference signal resource group.

[0310] Specifically, according to the different distribution of the M R high priority reference signal resources in the K S reference signal resources, B reference signal resource groups are generated, where B is an integer greater than or equal to 1.

[0311] For example, when M R = 2, K S = 4, When there are two high priority reference signal resources in {NZP-CSI-RS-ResourceId=n1, NZP-CSI-RS-ResourceId=n2, NZP-CSI-RS-ResourceId=n3, NZP-CSI-RS-ResourceId=n4}, the 6 reference signal resource groups that exist are, for example, Table 7. Each reference signal resource group includes a first field value corresponding to one.

[0312] Table 7

[0313] The embodiment of the present application does not limit the specific manner in which the terminal device determines the reference signal resource group to which the M R high priority reference signal resources belong according to the value of the first field, and the following exemplary description is given.

[0314] For example, the first field indicates the reference signal resource group. If the first field is "000", the terminal device can determine, based on the first field and Table 7, that NZP-CSI-RS-ResourceId=n1 and NZP-CSI-RS-ResourceId=n2 are high priority reference signal resources. If the first field is "001", the terminal device can determine, based on the first field and Table 7, that NZP-CSI-RS-ResourceId=n1 and NZP-CSI-RS-ResourceId=n3 are high priority reference signal resources. The same applies to the subsequent.

[0315] Optionally, the number of bits occupied by the first field is determined according to formula (1).

[0316] Optionally, the number of bits occupied by the first field is configured by the network device or predefined by the protocol, and is not limited.

[0317] In this case, the terminal device can determine the number M R of high priority reference signal resources according to the high priority reference signal resources indicated by the first indication information. R That is, the number M R of high priority reference signal resources does not need to be explicitly indicated.

[0318] Optionally, the number of bits occupied by the first field is related to the values of K S and M R , and satisfies formula (2).

[0319] Wherein, represents rounding up.

[0320] Example 3, the terminal device determines the number M of high priority reference signal resources according to the value of the first field R and the reference signal resource group to which the M R high priority reference signal resources belong, determines the M R high priority reference signal resources according to the reference signal resource group.

[0321] Specifically, according to the value of M R and the distribution of the M R high priority reference signal resources in the K S reference signal resources, C reference signal resource groups are generated, where C is an integer greater than or equal to 1.

[0322] For example, assuming that K S = 4, the reference signal resources are {NZP-CSI-RS-ResourceId = n1, NZP-CSI-RS-ResourceId = n2, NZP-CSI-RS-ResourceId = n3, NZP-CSI-RS-ResourceId = n4}, and the protocol predefines the value list of M R , for example, the value list of M R is {0, 1, 2}, M R = 0 represents that the K S reference signal resources do not include high priority reference signal resources, M R = 1 represents that the K S reference signal resources include 1 high priority reference signal resource, and M R = 2 represents that the K S reference signal resources include 2 high priority reference signal resources.

[0323] At this time there are four combinations, that is, the first field occupies 4 bits, and the correspondence between the value of the first field and the high priority reference signal resource is, for example, Table 8. Each reference signal resource group includes a one-to-one correspondence of the value of the first field.

[0324] Table 8

[0325] It should be understood that in this case, the first field can be used to indicate the number M R of high priority reference signal resources, and can also be used to indicate the reference signal resource group.

[0326] On the one hand, if the first field is “0000”, the terminal device can determine the KS If the first field is "0001", the terminal device can determine that NZP-CSI-RS-Resourcel=n1 is a high priority reference signal resource based on the first field and Table 8; if the first field is "0101", the terminal device can determine that NZP-CSI-RS-Resourcel=n1 and NZP-CSI-RS-Resourcel=n2 are high priority reference signal resources based on the first field and Table 8; and so on.

[0327] In this case, the terminal device can determine the number M of high priority reference signal resources according to the value of the first field. R That is, the number M of high priority reference signal resources does not need to be explicitly indicated. R .

[0328] On the other hand, as shown in Table 8, all 0 bits represent that K S reference signal resources do not include high priority reference signal resources; "0001" to "0100" represent that K S reference signal resources include 1 high priority reference signal resource; "0101" to "1010" represent that K S reference signal resources include 2 high priority reference signal resources; and the remaining values are invalid indications or reserved indications, that is, the terminal device can directly determine the number M of high priority reference signal resources according to the value of the first field. R .

[0329] Optionally, the number of bits occupied by the first field is determined according to formula (2).

[0330] Optionally, the number of bits occupied by the first field is configured by the network device or predefined by the protocol, and is not limited.
