[0162] The technical terms and related technical solutions in this application will be described below with reference to the accompanying drawings.

[0163] 1. Reference signal resource (RS resource):

[0164] The reference signal resource can be used to configure transmission attributes of the reference signal, for example, time-frequency resource location, port mapping relationship, power factor, and scrambling code, and the like. For details, refer to the relevant chapters about reference signal resources in the 3rd generation partnership project (3GPP) technical specification (TS) 38.211 and TS 38.331. The sending end (for example, a network device) of the reference signal can send the reference signal based on the reference signal resource, and the receiving end (for example, a terminal device) of the reference signal can receive the reference signal based on the reference signal resource. The reference signal resource can include one or more of the following: a channel state information reference signal (CSI-RS) resource, a channel state information interference measurement (CSI-IM) resource, an interference measurement resource, a channel measurement resource, or a channel state information-synchronization signal and physical broadcast channel block (CSI-SSB) resource. The CSI-RS resource can be a non zero power-channel state information reference signal (NZP-CSI-RS) resource or a zero power-channel state information reference signal (ZP-CSI-RS) resource. The NZP-CSI-RS resource is used for interference measurement and / or for channel measurement, and the ZP-CSI-RS resource is used for interference measurement. The NZP-CSI-RS resource is used to carry an NZP-CSI-RS, the NZP-CSI-RS is used for channel measurement, and the ZP-CSI-RS resource is used for interference measurement. The CSI-IM resource is used for interference measurement. The channel measurement resource is used for channel measurement, and the CSI-SSB resource is used for channel measurement. It should be understood that one resource being used for channel measurement means that channel measurement can be performed according to the reference signal carried on the resource, and one resource being used for interference measurement means that interference measurement can be performed according to the reference signal carried on the resource. For ease of description, the above reference signal resources are referred to as resources in the examples of the embodiments of the present application.

[0165] 2. Reference signal configuration

[0166] The reference signal configuration can include two parts of a reference signal resource configuration and a reference signal reporting configuration. The reference signal configuration can be a sounding reference signal (SRS) configuration, a CSI-RS configuration. Take the CSI-RS configuration as an example for description.

[0167] The CSI-RS configuration includes a channel state information (CSI) reporting configuration (CSI-ReportConfig) and a CSI resource configuration (CSI-ResourceConfig). It can be understood that the CSI reporting configuration and the CSI resource configuration are only names adopted for convenient description, and other names can also be used for naming, which is not limited in the present application.

[0168] The CSI reporting configuration can be used to configure parameters related to CSI reporting, such as a reporting configuration identifier (ReportConfigId), a reporting configuration type (reportConfigType), a reporting quantity (reportQuantity), and the like. The reporting configuration identifier can be used to mark the CSI reporting configuration, that is, one reporting configuration identifier can correspond to one CSI reporting configuration. The reporting configuration type is used to configure the type of reporting, which can be divided into periodic reporting, semi-persistent reporting, and aperiodic reporting. The reporting quantity can be used to configure the information of reporting. For example, the reporting quantity can include a CSI-RS resource indicator (CRI), a precoding matrix indication (PMI), a rank indication (RI), a layer indicator (LI), a channel quality indicator (CQI), a reference signal received power (RSRP), a reference signal received quality (RSRQ), a signal-to-noise ratio (SNR), a signal to interference plus noise ratio (SINR), and the like. Through different CSI-RS reporting configurations, different information reporting can be achieved.

[0169] The CSI resource configuration can be used to configure CSI-RS resource related information, such as a CSI resource configuration identifier (CSI-ResourceConfigId), and a CSI-RS resource used for measurement. The CSI resource configuration identifier is an identifier of the CSI resource configuration, used to mark the CSI resource configuration, and the CSI resource configuration identifier can be associated with the CSI resource configuration.

[0170] The above takes CRI, PMI, RI, LI, CQI, RSRP, RSRQ, SNR, SINR, and the like as examples to describe the measurement result. In actual implementation, other possible measurement results can also exist, which are not limited. The embodiments of the present application do not limit the specific content contained in the measurement result and the indication manner thereof.

[0171] The CSI-RS configuration can also be referred to as a CSI-RS measurement configuration, or other names, which are not limited in the embodiments of the present application.

[0172] 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).

[0173] 3, the flow of CSI reporting:

[0174] In a communication system using massive multiple input multiple output (massive MIMO) technology for communication, the data received by the receiving end of the data, such as a terminal device, can be the data after the data is precoded by the sending end of the data, such as a network device. The sending end of the data can perform precoding on the data according to the channel state information (CSI) reported by the receiving end of the data. The CSI can be reported by the receiving end of the data, and the following describes the flow of CSI reporting provided by the embodiments of the present application, taking the receiving end of the data as a terminal device and the sending end of the data as a network device.

[0175] Please refer to Figure 1 , Figure 1 the flowchart of CSI reporting provided by the embodiments of the present application. As shown in Figure 2 , the flowchart includes the following steps S101-S104:

[0176] S101, the network device sends a CSI-RS configuration to the terminal device.

[0177] The CSI-RS configuration can be carried in radio resource control (RRC) signaling. It should be understood that RRC is used only as an example, and in actual implementation, the CSI-RS configuration can also be carried in other possible signaling or information, which is not described here.

[0178] S102, the network device sends a CSI-RS to the terminal device on a CSI-RS resource. Correspondingly, the terminal device receives the CSI-RS from the network device on the CSI-RS resource.

[0179] In a communication system, such as a new radio (NR) system, the network device sends a CSI-RS on a CSI-RS resource for probing a downlink channel, and the terminal device receives the CSI-RS on a pre-configured CSI-RS resource for channel estimation.

[0180] The CSI-RS resource can be periodic, semi-static, or aperiodic. If the CSI-RS resource is aperiodic, the CSI-RS resource is a CSI-RS resource triggered by a downlink signaling, such as a trigger DCI, or a CSI-RS resource activated by a trigger DCI. The CSI-RS can be transmitted on the activated CSI-RS resource.

[0181] S103, the terminal device obtains CSI according to the CSI-RS.

[0182] The implementation principle of S103 can refer to the related description of obtaining CSI in the existing standard, which is not described here.

[0183] S104, the terminal device reports the CSI to the network device.

[0184] The CSI includes the above-mentioned reporting quantity.

[0185] 4. Beam:

[0186] A mobile communication system (for example, a 5G mobile communication system) can use high-frequency communication, that is, use high-frequency signals to transmit data. One major problem of high-frequency communication is that the signal energy decreases sharply with the transmission distance, resulting in a short signal transmission distance. In order to overcome this problem, high-frequency communication uses analog beam technology, which concentrates signal energy in a small angular range by weighting processing of an antenna array, forming a signal similar to a light beam (called an analog beam, simply referred to as a beam), thereby improving the transmission distance. Both the network device and the terminal device can use beams for transmission.

[0187] A beam can be referred to as a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, Quasi-colocation (QCL) information, a QCL assumption, a QCL indication, or the like in a protocol such as a new radio (NR) protocol. A beam can also be represented by a transmission configuration indicator state parameter or a spatial relation parameter. The transmission configuration indicator state can be referred to as a transmission configuration indicator state (TCI-state), a transmission configuration indication state (TCI-state), or a transmission configuration index state (TCI-state). Therefore, in this application, a beam can be replaced by a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, QCL information, a QCL assumption, a QCL indication, a TCI-state (e.g., a downlink TCI-state (DL TCI-state) and / or an uplink TCI-state (UL TCI-state)), or a spatial relation. The above terms are also equivalent to each other. A beam can also be replaced by other terms representing a beam, which are not limited in this application.

[0188] A beam for transmitting a signal can be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting.

[0189] For downlink communication, a transmission beam can also be referred to as a downlink transmission beam. Exemplarily, a downlink transmission beam can be indicated by any one of a spatial relation, a CSI-RS resource, a downlink TCI-state, an SSB resource, or a tracking reference signal (TRS) resource.

[0190] A beam for receiving a signal can be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting.

[0191] A transmission beam can refer to a distribution of signal strength in different directions in space after a signal is transmitted by an antenna.

[0192] In addition, a beam can be a wide beam, or a narrow beam, or other types of beams. The technology for forming a beam can be beamforming technology or other technology. The beamforming technology can be, for example, digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology, etc.

[0193] A beam is generally corresponding to a resource. For example, when performing beam measurement, a network device measures different beams through different resources, and a terminal device feeds back the measured resource quality, so that the network device knows the quality of the corresponding beam.

[0194] 5. Hybrid beamforming (HBF) architecture:

[0195] In the HBF architecture, one digital channel (which can also be referred to as a transceiver channel TRX) drives multiple antenna elements through multiple phase shifters. The relationship among the digital channel, the phase shifters, and the antenna elements is as follows: Figure 3As shown, one network device includes multiple transceiving channels, such as transceiving channel 1 to transceiving channel I, I being a positive integer, each transceiving channel can be connected to multiple phase shifters, and each phase shifter can drive multiple antenna elements. Taking transceiving channel 1 as an example, transceiving channel 1 can be connected to phase shifters 1 to 4 respectively, and each of the phase shifters 1 to 4 can drive multiple antenna elements. The large-scale antenna array of the network device can be implemented through the HBF architecture, in which case the downlink signal sent by the network device can adopt two-level weights in the analog domain and the digital domain. In a communication system, by adopting the HBF architecture, the cost can be reduced.

[0196] The network device can configure multiple reference signal resources associated with the same reference signal resource set for the terminal device, each reference signal resource corresponding to one beam, but when the resource type of the configured reference signal resource is aperiodic, the multiple reference signal resources can only be associated with the same time slot, that is, different analog beams can only occupy the same time slot for transmission. Under the HBF architecture, the network device uses multiple beams to implement coverage of the area within the cell corresponding to the network device, wherein different beams cover different areas. The beam involved in the embodiments of the present application can also be referred to as an analog beam.

[0197] In some scenarios, such as scenarios with rich multipath in channel environments, such as communication in intermediate frequency bands and / or low frequency bands, the same terminal device can be served by different beams. When there are multiple terminal devices within the coverage range of the network device, the multiple terminal devices can multiplex resources for transmission. In order to realize the multiplexing of resources, the terminal device needs to measure the channel state information on multiple beams for data scheduling and modulation and coding scheme (MCS) decision of the network device, such as beam sweeping or beam training. Among them, beam sweeping or beam training refers to the process of selecting a beam from multiple different beams. Since the real-time traffic and user scheduling demand in the network, the terminal devices to be scheduled within the coverage range of the network device at different times, and the amount of traffic to be scheduled for each terminal device are all dynamically variable, the beams that need to be measured by the terminal device can be different. For example, as shown in (a) of FIG. 3, when terminal device 301 and terminal device 302 have traffic to be scheduled within the coverage range of the network device, terminal device 302 needs to measure beam 1 (beam 1) and beam 2 (beam 2). For another example, as shown in (b) of FIG. 3, if terminal device 302, terminal device 303 and terminal device 304 have traffic to be scheduled within the coverage range of the network device, then terminal device 302 needs to measure beam 2 (beam 2) and beam 3 (beam 3). Figure 3 Figure 4

[0198] ​​Considering the implementation constraints of the HBF architecture, the network device can only send the signal of one analog beam at the same time, and the signals of different analog beams can only be sent in a time-division manner; the multiple reference signal resources of the aperiodic reference signal resource set can only occupy the same time slot, and the number of symbols in a time slot is limited, so when the time-division transmission of multiple analog beams cannot be carried in the symbols in a time slot, the terminal device cannot measure the channel state information of multiple analog beams. In this case, how to realize the channel state information measurement of multiple analog beams by the same terminal device is a problem to be solved.

[0199] The technical solutions in the present application will be described below with reference to the drawings.

Furthermore, combinations of these solutions can also be used.

[0202] In addition, in the embodiments of the present application, the words such as "example", "for example" and the like are used to represent an example, illustration or description. 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 intended to present the concept in a specific manner.

[0203] First, in the present application, "for indicating" can include for directly indicating and for indirectly indicating. When describing that "information" is used to indicate A, it can include that the information directly indicates A or indirectly indicates A, and does not mean that A must be carried in the information.

[0204] The information indicated by one information is referred to as to-be-indicated information. In a specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, directly indicating the to-be-indicated information, 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 only indicated in 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, specified by a protocol), thereby reducing the indication overhead to a certain extent. Meanwhile, the common part of each information can also be identified and uniformly indicated, so as to reduce the indication overhead caused by separately indicating the same information.

[0205] In addition, the specific indication manner is not limited to the above indication manner and various combinations thereof. The specific details of various indication manners are not described herein. As can be known from the above, for example, when multiple information of the same type needs to be indicated, the indication manner of different information can be different. In a specific implementation process, the required indication manner can be selected according to specific needs, and the selected indication manner is not limited by the embodiments of the application. In this way, the indication manner involved in the embodiments of the application should be understood as covering various methods that can enable the to-be-indicated party to know the to-be-indicated information.

[0206] The to-be-indicated information can be sent as a whole, or can be divided into multiple sub-information and sent separately, and the sending period and / or sending occasion of the sub-information can be the same or different. The specific sending method is not limited by the application. The sending period and / or sending occasion of the sub-information can be predefined, for example, predefined according to a protocol, or configured by the transmitting end device by sending configuration information to the receiving end device. The configuration information can include, for example, but not limited to, one of RRC signaling, medium access control (MAC) layer signaling and physical layer signaling, or a combination of at least two of them. The MAC layer signaling includes, for example, a MAC control element (CE), and the physical (PHY) layer signaling includes, for example, DCI.

[0207] Second, in the embodiments shown below, the first, second and various numbers are only distinguished for the convenience of description, and do not limit the scope of the embodiments of the application. For example, different indication information is distinguished.

[0208] Thirdly, the "preset" or "predefined" or "preconfigured" can be realized by pre-storing corresponding codes, tables or other means for indicating relevant information in the devices (e.g., including terminal devices and network devices), and can also be pre-defined in the protocol. The specific implementation manner is not limited in the present application. Wherein, the "storing" can mean storing in one or more memories. The one or more memories can be separately arranged or integrated in the encoder or decoder, processor or communication device. The one or more memories can be partially separately arranged and partially integrated in the decoder, processor or communication device. The type of the memory can be any form of storage medium, which is not limited in the present application.

[0209] Fourthly, the "protocol" involved in the embodiments of the present application can refer to a standard protocol in the communication field, which can include the LTE protocol and the NR protocol of the 3GPP and related protocols applied in future communication systems, which is not limited in the present application.

[0212] In order to facilitate the understanding of the embodiments of the present application, first, the communication system shown in Figure 4 will be taken as an example to describe the communication system applicable to the embodiments of the present application in detail. Exemplarily, Figure 4 the architecture of a communication system applicable to the method provided by the embodiments of the present application is shown.

[0213] As shown in Figure 4 , the communication system includes at least one network device (such as network device 410a and network device 410b) and at least one terminal device (such as terminal devices 420a to 420j).

[0214] The terminal device can be connected to the network device in a wireless manner, and the network device can be connected to the core network (not shown in Figure 4 ) in a wired or wireless manner.

[0215] The network device and the terminal device can interact information.

[0216] The terminal device can be a terminal with transceiver function. The terminal device can also be referred to as a user equipment (UE), an access terminal, a subscriber unit, a user station, a mobile station (MS), a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus.

The terminal device can also be other devices with terminal function, for example, the terminal device can also be a device with terminal function in D2D communication. The embodiments of the present application do not limit the device form of the terminal device, and the device for realizing the function of the terminal device can be the terminal device; or it can be a device capable of supporting the terminal device to realize the function, for example, a communication module, a chip, a chip system, other components or assemblies, or a circuit or functional assembly, etc. The device can be installed in the terminal device or used with the terminal device. The chip system can be composed of a chip, or it can include a chip and other discrete devices.The terminal device in various forms described above can also be referred to as a terminal-side device.

[0217] In an embodiment of the present application, the network device can be a device with wireless transceiving function. For example, the network device can be a device located in an access network (AN) of a communication system, and can be used to provide access services for terminals. In a possible scenario, the network device can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a base station in a future communication system, etc. The network device can be a macro base station (such as Figure 4 eNodeB), a micro base station or an indoor station (such as Figure 5 eNodeB), a relay node or a donor node, or a wireless controller in a cloud radio access network (CRAN) scenario. Optionally, the network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in V2X technology can be a road side unit (RSU). All or part of the functions of the network device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The network device in the present application can also be a logical node, a logical module or software capable of implementing all or part of the functions of the network device.

[0218] Optionally, in at least one network device, there can be a network device integrated with a reader, or there can be a network device with a reader function.

[0219] In another possible scenario, a terminal is assisted by multiple network devices to implement wireless access, and different network devices respectively implement part of functions of a base station. For example, a network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, for example, in a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0220] In different systems, the CU (or centralized unit control plane (CU-CP)) and the centralized unit user plane (CU-UP)), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (O-RAN or ORAN) system, the CU can also be referred to as an open centralized unit (O-CU) (open CU), the DU can also be referred to as an open distributed unit (O-DU), the CU-CP can also be referred to as an open centralized unit control plane (O-CU-CP), the CU-UP can also be referred to as an open centralized unit user plane (O-CU-UP), and the RU can also be referred to as an open radio unit (O-RU). For the convenience of description, the CU, the CU-CP, the CU-UP, the DU, and the RU are taken as examples for description in this application. Any one of the CU (or the CU-CP, the CU-UP), the DU, and the RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0221] In the embodiments of the present application, the form of the network device is not limited, and the device for implementing the function of the network device can be the network device; or can be a device capable of supporting the network device to implement the function, such as a communication module, a chip, a chip system, other components or assemblies, or a circuit or functional assembly, etc. The device can be installed in the network device or used in matching with the network device. The chip system can be composed of a chip, or can include a chip and other discrete devices. The network device in various forms described above can also be referred to as a network side device.

[0222] The following illustrates the connection relationship among the core network device, the network device and the terminal device in the O-RAN system.

[0223] As shown in Figure 6 , the network device is an access network device (RAN, which can be an eNB or a gNB or an access network device in a future communication system). The access network device communicates with the core network (CN) through a backhaul link, and communicates with the terminal device through an air interface. The access network device can include a BBU and a RU. The BBU in the access network device communicates with the core network device through the backhaul link, and the RU in the access network device communicates with at least one terminal device through the air interface. The BBU communicates with at least one RU through a fronthaul link, and the BBU and the RU can be co-located or not.

[0224] The BBU includes at least one CU and at least one DU, and the CU and the DU can communicate through at least one midhaul link. The CU in the BBU communicates with the core network through the backhaul link, and the DU in the BBU communicates with the RU through the fronthaul link.

[0225] In the O-RAN system, the function division of the RAN network element and the protocol layer structure are as shown in Figure 7 .

[0226] In some examples, the CU is a logical node that carries the RRC layer, the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU is connected to network nodes such as the core network through some interfaces, which can be E2 interfaces or the like. Optionally, the CU can have part of the functions of the core network. The CU (e.g., the PDCP layer and higher layers) is connected to the DU (e.g., the radio link control (RLC) and lower layers) through some interfaces, which can be F1 interfaces or the like. In some examples, these interfaces (e.g., the F1 interface) can provide CP and UP, interface management, system information management, UE context management, RRC message transmission, and the like. The F1AP is an application protocol of the F1 interface, which defines the signaling procedures of the F1 in some examples. The F1 interface supports the control plane F1-C and the user plane F1-U.

[0227] In some examples, a CU can be split into a CU-CP (control unit-control plane) and a CU-UP (control unit-user plane), where the CU-CP is a logical node carrying the control plane part of PDCP (PDCP-C) layer and RRC layer, for implementing the control plane function of the CU. The CU-CP can interact with a network element in the core network for implementing the control plane function. The network element in the core network for implementing the control plane function can be an access and mobility function network element, for example, an access and mobility management function (AMF) in a 5G system. The AMF network element is configured to be responsible for mobility management in a mobile network, such as location updating of a terminal device, registration of the terminal device to a network, handover of the terminal device, and the like. The CU-UP is a logical node carrying the user plane part of PDCP (PDCP-U) layer and SDAP layer, for implementing the user plane function of the CU. The CU-UP can interact with a network element in the core network for implementing the user plane function. The network element in the core network for implementing the user plane function, for example, a user plane function (UPF) in a 5G system, is configured to be responsible for forwarding and receiving data in a terminal device. 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 requiring to meet a shorter delay requirement in processing time are arranged in the DU, and functions not requiring to meet the delay requirement are arranged in the CU.

[0228] In some examples, the DU is a logical node carrying the RLC layer, the MAC layer, the higher physical layer (Higher PHY), 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 physical layer includes part of the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like.

[0229] In some examples, a RU is a logical node that hosts lower physical layer (Lower PHY) and radio frequency (RF) links. In some examples, a RU can be a 3GPP transmission reception point (TRP) or a remote radio head (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.

[0230] A DU and a RU can or can not be co-located. A DU and a RU exchange control plane information and user plane information over a fronthaul link via a lower layer split-control, user and synchronization plane (LLS-CUS) interface. The LLS-CUS can include a lower-layer split-control (LLS-C) interface and a lower-layer split-user (LLS-U) interface that provide control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, a control plane (C-Plane) (e.g., an O-RAN CUS-Plane) refers to real-time control between a DU and a RU. A DU and a RU have a LLS-M interface of a fronthaul link to exchange management information, and a management plane (M-Plane) (e.g., an O-RAN M-Plane) refers to non-real-time management operations between a DU and a RU.

[0231] 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 the PHY layer can include a portion of functionality of the PHY layer that is closer to a MAC layer, and the low-layer functionality in the PHY layer can include another portion of functionality of the PHY layer that is closer to a mid-RF side.

[0232] The management system is used to implement functions such as mobility management, data processing, session management, policy and charging. The names of devices implementing the management system in systems of different access technologies can be different, and the embodiments of the present application do not limit this. Taking the 5th generation (5G) mobile communication system as an example, the management system can include AMF, session management function (SMF), policy control function (PCF) or UPF, etc.

[0233] Figure 7 The figure is a schematic diagram of the architecture when the network device and the terminal device communicate. As shown in Figure 4 , the terminal device includes a processor 701, a memory 702 and a transceiver 703, and the transceiver 703 includes a transmitter 703a, a receiver 703b and an antenna 703c. The network device includes a processor 711, a memory 712 and a transceiver 713, and the transceiver 713 includes a transmitter 713a, a receiver 713b and an antenna 713c. The receiver 703b can be used to receive transmission control information through the antenna 703c, and the transmitter 703a can be used to send transmission feedback information to the network device through the antenna 703c. The transmitter 713a can be used to send transmission control information to the terminal device through the antenna 713c, and the receiver 713b can be used to receive transmission feedback information sent by the terminal device through the antenna 713c.

[0234] It should be noted that the method of auxiliary channel measurement provided by the embodiments of the present application can be applied between any two devices, such as between a terminal device and a network device, and the specific implementation can refer to the following method embodiments, which will not be described here. Figure 4

[0235] It should be noted that the scheme in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced by the names of the corresponding functions in other communication systems.

[0236] It should be understood that Figure 4 only for the convenience of understanding, a simplified schematic diagram is shown, and other network devices and / or other terminal devices can also be included in the communication system, Figure 4 which are not shown in the figure.

[0237] The following describes the scheme provided by the embodiments of the present application in combination with a first device and a second device, wherein the first device can be any one of the terminal devices in the communication system provided by the above Figure 4 , and the second device can be any one of the network devices in the communication system provided by the above Figures 8-18 .

[0238] ​To solve the above problems, in a possible embodiment of the present application, a method for assisting channel measurement is provided. In the method, a second device can send first information to a first device, the first information being used to indicate an offset of each resource in a plurality of resources. The first device can send a reference signal according to the first information. The offset of each resource is related to a first reference time slot and a time slot where each resource is located. In this way, time division transmission of the reference signal can be realized, so that the reference signal can be transmitted on multiple beams and applied to more scenarios.

[0239] In another possible embodiment of the present application, a method for assisting channel measurement is also provided. In the method, a second device can send first information to a first device, the first information being used to indicate a time slot where at least one resource in a first resource set is located and a relative position relationship between the time slot and a time slot where each resource in the first resource set is located. The first device can receive a reference signal on multiple time slots according to the first information, so that the reference signal can be transmitted on multiple beams and applied to more scenarios.

[0240] The above will be described in detail below. Figure 8 The method for assisting channel measurement provided by the embodiments of the present application will be described in detail.

[0241] Exemplarily, Figure 1 The method for assisting channel measurement provided by the embodiments of the present application will be described in detail. Figure 4 The method for assisting channel measurement can be applied to Figure 8 communication between a terminal device and a network device as shown in

[0242] As shown in Figure 9 , the method for assisting channel measurement comprises the following steps:

[0243] A method for assisting channel measurement comprises:

[0244] S801, a second device sends first information. Correspondingly, a first device receives the first information.

[0245] The first information is used to indicate an offset of each resource in a plurality of resources. The offset of each resource in the plurality of resources is related to a first reference time slot and a time slot where each resource is located.

[0246] In an embodiment of the present application, the first reference time slot can be a time slot related to the offset of each of the plurality of resources, or in other words, the offset of each of the plurality of resources is determined according to the first reference time slot. For example, the first reference time slot can be the offset of any one of the plurality of resources, or the reference time slot used to determine the offset of any one of the plurality of resources is determined according to the first reference time slot. Alternatively, the first reference time slot can be the time slot containing the trigger DCI, and the trigger DCI is used to activate the plurality of resources.

[0247] In a possible implementation, the plurality of resources includes K resources, K being an integer greater than or equal to 2. As an example, the plurality of resources can include a first resource and a second resource.

[0248] Alternatively, the first resource can be the first resource in the plurality of resources, and the second resource can be the second resource in the plurality of resources.

[0249] Alternatively, the plurality of resources can be sorted in ascending order or descending order based on resource indexes, the first resource can be the first sorted resource in the plurality of resources, and the second resource can be the second sorted resource in the plurality of resources. For example, the index of the time slot in which the first resource is located can be less than the index of the time slot in which the second resource is located, or the index of the time slot in which the second resource is located can be greater than the index of the time slot in which the second resource is located. In other words, the time domain position of the first resource can be before the second resource, or after the second resource.

[0250] Alternatively, the first resource can be any one of the plurality of resources, and the second resource can be any one of the plurality of resources except the first resource.

[0251] It should be understood that the plurality of resources can further include more resources. For example, the plurality of resources can further include a third resource; or the plurality of resources can further include a third resource and a fourth resource; or the plurality of resources can further include a fourth resource, a fifth resource, or the plurality of resources can further include a fourth resource, a fifth resource, a sixth resource, and so on, which will not be listed one by one here.

[0252] The resources in the plurality of resources can be resources activated by the trigger DCI, or in other words, the resources in the plurality of resources can be resources activated by the trigger DCI. As an example, the plurality of resources can include resources for interference measurement and / or resources for channel measurement. For example, the plurality of resources can include one or more of the following resources: CSI-RS resource, CSI-IM resource, channel measurement resource, or interference measurement resource, or CSI-SSB resource. The CSI-RS resource is used to carry CSI-RS, and the CSI-RS is used for channel measurement or interference measurement.

[0253] In a possible implementation, the multiple resources include at least resources in a resource set.

[0254] Optionally, the multiple resources can belong to a same resource set, e.g., resources in a first resource set. In other words, the multiple resources are all resources in a same resource set. For example, in a case that the multiple resources include only a first resource and a second resource, the first resource and the second resource can be resources in a same resource set. As an example, the first resource set can be a CSI-RS resource set, and the CSI-RS set can include multiple CSI-RS resources, and the multiple resources are all CSI-RS resources in the CSI-RS resource set. Or, the first resource set can be a CSI-IM resource set, and the CSI-IM resource set can include multiple CSI-IM resources, and the multiple resources are all CSI-IM resources in the CSI-IM resource set. Or, the first resource set can be a channel measurement resource set, and the channel measurement resource set can include multiple channel measurement resources, and the multiple resources are all channel measurement resources in the channel measurement resource set. Or, the first resource set can be an interference measurement resource set, and the interference measurement resource set can include multiple interference measurement resources, and the multiple resources are all channel measurement resources in the interference measurement resource set. Or, the first resource set can be a CSI-SSB resource set, and the CSI-SSB resource set can include multiple CSI-SSB resources, and the multiple resources are all CSI-SSB resources in the CSI-SSB resource set.

[0255] Or, optionally, the multiple resources can belong to multiple resource sets. For example, in a case that the multiple resources include a first resource and a second resource, the first resource and the second resource can be resources in different resource sets. As an example, the multiple resources can include resources in a first resource set and resources in a second resource set. The second resource set can be a CSI-RS resource set, or a CSI-IM resource set, or a channel measurement resource set, or an interference measurement resource set, or a CSI-SSB resource set, and the second resource set is different from the first resource set. As an example, the first resource set can be a CSI-RS resource set for channel measurement, and the second resource set can be a CSI-IM resource set for interference measurement, or a NZP-CSI-RS resource set for interference measurement. It should be understood that the multiple resources can also include resources in more than two resource sets. For example, the multiple resources can include a NZP-CSI-RS resource set for channel measurement, a CSI-SSB resource set for channel measurement, a CSI-IM resource set for interference measurement, and a NZP-CSI-RS resource set for interference measurement.

[0256] The first reference time slot is a time slot containing the triggering DCI, and the triggering DCI is used to trigger multiple resources, or in other words, the triggering DCI is used to activate multiple resources. In this way, it can assist in realizing channel state information measurement on multiple beams in a non-periodic resource reporting scenario.

[0257] The time slot containing the triggering DCI can be determined by the second device. It should be understood that the time slot containing the triggering DCI can also be referred to as the time slot in which the triggering DCI is located.

[0258] The offset of one resource is used to determine the time slot in which the resource is located. Each resource in the multiple resources has its own offset, and the offsets of two different resources in the multiple resources can be the same or different.

[0259] The offset of each resource in the multiple resources is related to the first reference time slot and the time slot in which each resource is located, or in other words, the offset of the k'th resource in the multiple resources is related to the time slot in which the k'th resource is located and the first reference time slot. The offset of the k'th resource in the multiple resources relative to the time slot in which the k'th resource is located and the first reference time slot can be understood as the time slot offset of the k'th resource relative to the first reference time slot. Alternatively, the offset of the k'th resource is the time slot offset of the k'th resource relative to the reference time slot corresponding to the k'th resource, and the reference time slot corresponding to the k'th resource is determined based on the first reference time slot. Alternatively, the information used to determine the offset of the k'th resource in the multiple resources includes the time slot in which the k'th resource is located and the first reference time slot. It should be understood that the information used to determine the offset of the k'th resource in the multiple resources can also include a target correspondence, and in this case, it can also be said that the offset of the k'th resource in the multiple resources is determined according to the time slot in which the k'th resource is located, the first reference time slot, and the target correspondence. k' is a positive integer and k' is less than or equal to K.

[0260] In one possible implementation, the offset of the first resource in the multiple resources is determined according to the time slot in which the first resource is located and the first reference time slot, and the offset of the k'th resource in the multiple resources is determined according to the time slot in which the k'th resource is located and the time slot in which the k-1'th resource in the multiple resources is located. Alternatively, the offset of the first resource in the multiple resources is determined according to the time slot in which the first resource is located and the first reference time slot, and the offset of the k'th resource in the multiple resources is determined according to the time slot in which the k'th resource is located and the time slot in which the first resource in the multiple resources is located. Alternatively, the offset of each resource in the multiple resources is determined according to the time slot in which each resource is located and the first reference time slot. Wherein, k is a positive integer greater than or equal to 2, and k is less than or equal to K.

[0261] In a possible implementation, the offset of each resource of the plurality of resources can be determined by the second device according to a time slot in which each resource of the plurality of resources is located, the first reference time slot, and the target correspondence relationship. The time slot in which each resource of the plurality of resources is located can be determined by the second device according to a time slot in which a resource used to transmit a reference signal, such as a CSI-RS, a CSI-IM, or a channel measurement reference signal, is located. The first reference time slot can also be determined by the second device.

[0262] As an example, the target correspondence relationship can include a correspondence relationship between a time slot in which each resource of the at least two resources is located, a reference time slot of each resource, and an offset of each resource. The target correspondence relationship can be one of a plurality of correspondence relationships. Each correspondence relationship of the plurality of correspondence relationships can include a correspondence relationship between a time slot in which each resource of the at least two resources is located, a reference time slot of each resource of the at least two resources, and an offset of each resource of the at least two resources. It should be understood that the number of resources of the at least two resources involved in different correspondence relationships can be the same or different. The target correspondence relationship is illustrated below in relation to correspondence relationship 1 to correspondence relationship 3. The plurality of correspondence relationships can include correspondence relationship 1, correspondence relationship 2, and correspondence relationship 3. The correspondence relationship 1 can include that a reference time slot of a first resource of the at least two resources is a time slot containing the triggering DCI, and an offset of the first resource of the at least two resources is an offset between a time slot in which the first resource of the at least two resources is located and the time slot containing the triggering DCI; a reference time slot of an mth resource of the at least two resources is a time slot in which an (m-1)th resource of the at least two resources is located, and an offset of the mth resource of the at least two resources is an offset between a time slot in which the mth resource of the at least two resources is located and the time slot in which the (m-1)th resource of the at least two resources is located. m is an integer greater than or equal to 2, and m is less than M, where M is the number of resources of the at least two resources, and M is greater than or equal to K. Alternatively, the reference time slot of the first resource of the at least two resources is the first reference time slot, and the reference time slot of the mth resource of the at least two resources is the reference time slot of the (m-1)th resource of the at least two resources. At this time, the offset of an m'th resource of the at least two resources is an offset between a time slot in which the m'th resource of the at least two resources is located and the reference time slot of the m'th resource. m' is a positive integer, and m' is less than M. iM is greater than or equal to K.

[0263] It can also be understood that the correspondence relationship 1 can include the correspondence relationship shown in Table 1 as follows:

[0264] Table 1

[0265]

[0266] The correspondence relationship 2 includes: the reference time slot of the first resource in the at least two resources is the time slot containing the triggering DCI, and the offset of the first resource in the at least two resources is the offset between the time slot containing the triggering DCI and the time slot containing the first resource in the at least two resources; the reference time slot of the mth resource in the at least two resources is the time slot containing the first resource in the at least two resources, and the offset of the mth resource in the at least two resources is the offset between the time slot containing the mth resource in the at least two resources and the first resource in the at least two resources. In other words, the reference time slot of the first resource in the at least two resources is the first reference time slot, the reference time slot of the mth resource in the at least two resources is the reference time slot of the first resource in the at least two resources, and the offset of the m'th resource in the at least two resources is the offset between the time slot containing the m'th resource in the at least two resources and the reference time slot of the m'th resource.

[0267] It can also be understood that the correspondence relationship 2 can include the correspondence relationship shown in Table 2 as follows:

[0268] Table 2

[0269]

[0270] The correspondence relationship 3 can include: the reference time slot of the pth resource in the at least two resources is the time slot containing the triggering DCI, and the offset of the pth resource in the at least two resources is the offset between the time slot containing the pth resource in the at least two resources and the time slot containing the triggering DCI. P is a positive integer less than or equal to P, and P is greater than or equal to K. In other words, the reference time slot of the pth resource in the at least two resources is the first reference time slot, and the offset of the pth resource in the at least two resources is the offset between the time slot containing the pth resource in the at least two resources and the reference time slot of the pth resource.

[0271] It can also be understood that the correspondence relationship 3 can include the correspondence relationship shown in Table 3 as follows:

[0272] Table 3

[0273]

[0274] It should be understood that the above-mentioned multiple correspondence relationships, correspondence relationship 1 to correspondence relationship 3 are all for example, and in actual implementation, fewer or more correspondence relationships can be included in the multiple correspondence relationships, and any one of the correspondence relationship 1 to the correspondence relationship 3 can also have other description ways, which will not be described here.

[0275] In a possible implementation, in the embodiments of the present application, the offset of the resource is a time slot offset, or a time slot offset of an available time slot. In other words, the type of the offset is a time slot offset, or a time slot offset of an available time slot.

[0276] The offset herein can refer to the offset of any one of the plurality of resources. For example, any one of the first offset to the third offset.

[0277] In a possible implementation, the available time slot is a time slot that satisfies one or more of the following: a time slot in which a downlink symbol and / or a flexible symbol satisfies a time domain position of at least one reference signal resource in the reference signal resource set, or a time slot that meets a time domain resource requirement. Or, a time slot in which a time interval between a time slot containing the triggering DCI and a time interval meets a time requirement (the time requirement is related to a terminal capability, or is predefined by a protocol, or is related to a processing time required for demodulation of the DCI). Or, a time slot in which all symbols are downlink symbols. Or, a downlink time slot that is not occupied by a synchronization signal and physical broadcast channel block (SSB). Or, a downlink time slot that is not occupied by remaining minimum system information (RMSI). Or, a time slot in which the number of symbols available for downlink transmission is greater than or equal to N, where N is a positive integer, and the value of N is related to the number of ports contained in at least one reference signal resource in the reference signal resource set, or is predefined by a protocol.

[0278] As an example, the time slot in which the time interval between the time slot containing the triggering DCI and the time interval meets the time requirement can refer to a time slot in which the time interval between the time slot containing the triggering DCI and the time interval is greater than or equal to a first threshold value. The first threshold value is a time length threshold value, and is related to a terminal capability, or is predefined by a protocol, or is related to a processing time required for demodulation of the DCI.

[0279] In the embodiments of the present application, the available time slot can be a downlink time slot, a special time slot, or a flexible time slot. For example, the time slot that is not occupied by the synchronization signal and physical broadcast channel block (SSB) can refer to a downlink time slot, a special time slot, or a flexible time slot that is not occupied by the SSB. The time slot that is not occupied by the remaining minimum system information (RMSI) can refer to a downlink time slot, a special time slot, or a flexible time slot that is not occupied by the remaining minimum system information (RMSI). The non-uplink time slot can be a downlink time slot, a special time slot, or a flexible time slot.

[0280] The downlink time slot refers to a time slot in which all symbols are downlink symbols.

[0281] An uplink time slot is a time slot in which all symbols are uplink symbols.

[0282] A special time slot is a time slot in which both uplink symbols and downlink symbols are included.

[0283] A flexible time slot refers to a time slot in which at least one flexible symbol is included. The flexible symbol can be used to transmit a downlink signal or an uplink signal, and the signal direction that can be carried is flexible.

[0284] N is a positive integer, and N is determined according to the number of time domain symbols required to be occupied by one CSI-RS resource (for example, N is greater than or equal to the number of time domain symbols required to be occupied by one CSI-RS resource), or N can be agreed by a protocol, or configured by the second device to the first device, or N can be determined according to the capability information reported by the first device. It should be understood that the capability information reported by the first device is the capability information of the terminal device.

[0285] Optionally, the offset of the resource is a time slot offset, which refers to the offset of all time slots, such as downlink time slots, uplink time slots, flexible time slots, and special time slots, of a time slot in which a resource is located relative to a reference time slot corresponding to the resource. In this case, the offset of the resource can be used to indicate that the resource is located on the qth time slot after the reference time slot.

[0286] The offset of the resource is a time slot offset of available time slots, which refers to the offset of available time slots of a time slot in which a resource is located relative to a reference time slot corresponding to the resource. The time slot offset of available time slots of the resource can be used to indicate that the resource is located on the qth available time slot after the reference time slot.

[0287] The offset of the resource is illustrated below in combination with specific time slots. It is assumed that the offset of the resource is 0 when the resource is in the same time slot relative to the reference time slot of the resource, and the offset of the resource is q when the resource is in the qth time slot after the reference time slot. It is assumed that the distribution of uplink time slots, downlink time slots, and special time slots in time slots r to time slots r+17 is as follows: Figure 9As shown in (a), the multiple resources include eight resources, namely resources 1 to resources 8. The first reference time slot is time slot r+3. Resource 1 is located in time slot r+4, resource 2 in time slot r+5, resource 3 in time slot r+8, resource 4 in time slot r+9, resource 5 in time slot r+10, resource 6 in time slot r+13, resource 7 in time slot r+14, and resource 8 in time slot r+15. The offsets of resources 1 to 8 are represented by Of1 to Of8 respectively. The time slot offsets of each resource from resources 1 to 8, their types, target correspondences, and the relationship between the first reference time slot are shown in Table 4 below.

[0288] Table 4

[0289]

[0290] Assuming the distribution of uplink time slots, downlink time slots, and special time slots from time slot r to time slot r+17 is as follows: Figure 10 As shown in (b), the multiple resources include eight resources, namely resources 1 to resources 8. The first reference time slot is time slot r. Resource 1 is located in time slot r+3, resource 2 in time slot r+4, resource 3 in time slot r+5, resource 4 in time slot r+8, resource 5 in time slot r+9, resource 6 in time slot r+10, resource 7 in time slot r+13, and resource 8 in time slot r+14. The offsets of resources 1 to 8 are represented by Of1 to Of8 respectively. The time slot offsets of each resource from resources 1 to 8, the offset types, target correspondences, and the relationships with the first reference time slots are shown in Table 5 below.

[0291] Table 5

[0292]

[0293] Where r is a positive integer.

[0294] In this embodiment of the application, the first information is used to indicate the offset of each resource among multiple resources, and may include: the first information is used to indicate the offset of each resource among K resources.

[0295] In the case where multiple resources include a first resource and a second resource, the first information is used to indicate the offset of each of the multiple resources, and may include: the first information indicating a first offset of the first resource and a second offset of the second resource.

[0296] The first offset is associated with the first time slot and a first reference time slot, and the first offset is used to determine the first time slot. The second offset is associated with the second time slot and a second reference time slot, and the second offset is used to determine the second time slot. The first time slot is a time slot in which the first resource is located. The second time slot is a time slot in which the second resource is located.

[0297] The first offset is associated with the first time slot and a first reference time slot, and the first offset is used to determine the first time slot. The second offset is associated with the second time slot and a second reference time slot, and the second offset is used to determine the second time slot. The first time slot is a time slot in which the first resource is located. The second time slot is a time slot in which the second resource is located. The first time slot is a time slot in which the first resource is located. The second time slot is a time slot in which the second resource is located.

[0298] In an example of the target correspondence relationship, the trigger DCI can be used to activate the first resource and the second resource, and the second reference time slot is the first time slot, when the target correspondence relationship is the correspondence relationship 1 or the correspondence relationship 2. Alternatively, when the target correspondence relationship is the correspondence relationship 3, the second reference time slot is the first reference time slot.

[0299] The second offset is associated with the second time slot and a second reference time slot, and the second offset is used to determine the second time slot. The second offset is the offset between the second time slot and the second reference time slot.

[0300] In an example of the offset being a time slot offset, the first offset is a time slot offset, and the second offset is a time slot offset. In an example of the offset being a time slot offset of an available time slot, the first offset is a time slot offset of an available time slot, and the second offset is a time slot offset of an available time slot.

[0301] In some possible implementations, the offset of at least one resource of the plurality of resources can be an offset of a resource set in which the resource is located. For example, in a case where the plurality of resources includes a first resource and a second resource, the offset of the first resource can be an offset of a resource set in which the resource is located. For example, the offset of at least one resource of the plurality of resources can be an offset indicated by a field “aperiodicTriggeringOffset”. In this way, an existing field can be reused, and signaling overhead can be reduced.

[0302] In another possible implementation, the offset of each resource set to which the plurality of resources belong is a first type of offset. In this case, the offset of each resource in the plurality of resources can be determined according to the offset of the resource set to which the resource belongs (e.g., the offset indicated in the field of “aperiodic triggering offset”) and the second type of offset corresponding to the resource. The reference time slot of the second type of offset of a resource is determined according to the offset of the resource set to which the resource belongs. As an example, the offset of the k’th resource in the plurality of resources can be the sum of the offset of the resource set to which the k’th resource in the plurality of resources belongs and the second type of offset of the k’th resource. Optionally, in the case where the plurality of resources includes a first resource and a second resource, the first resource belongs to resource set A and the second resource belongs to resource set B, the offset (i.e., the first offset) of the first resource is the sum of the first type of offset of resource set A and the second type of offset of the first resource, and the offset (i.e., the second offset) of the second resource is the sum of the first type of offset of resource set B and the second type of offset of the second resource. For example, in the case where the plurality of resources includes a first resource and a second resource, if the first resource and the second resource belong to the same resource set and the offset (i.e., the first offset) of the resource set is 1, the second type of offset of the first resource is 2, and the second type of offset of the second resource is 1, the offset of the first resource is 3, and the offset (i.e., the second offset) of the second resource is 2. In this case, the first information can indicate the offset of each resource in the plurality of resources by indicating the offset of the resource set to which each resource in the plurality of resources belongs and the second type of offset of each resource. In this way, the existing field can be reused, and signaling overhead can be reduced.

[0303] In still some possible implementations, the first information can indicate the offset of each resource in the plurality of resources by indicating a third type of offset corresponding to the plurality of resources and a fourth type of offset of each resource in the plurality of resource sets. The third type of offset can be smaller than the smallest offset in the offsets of the plurality of resources, and the fourth type of offset of each resource is the offset of the resource other than the third type of offset, i.e., the difference between the fourth type of offset and the third type of offset of the resource. In this way, signaling overhead can be reduced.

[0304] In the embodiments of the present application, the first information can be carried in downlink information. For example, the first information can be carried in one or more of the following: RRC signaling, or MAC CE, or DCI. In the case where the first information is carried in RRC signaling, the first information can be carried in a reference signal configuration, such as a CSI-RS configuration.

[0305] As an example, the first information can be carried in a CSI-RS resource information element, such as a non-zero power CSI-RS resource set (NZP-CSI-RS-ResourceSet) information element. For example, a new information element can be added in the CSI-RS resource set information element to indicate the first information. In this way, one offset pattern can be configured for each resource set, so that the location of the configured resources is more flexible.

[0306] Alternatively, the first information can be carried in a CSI-RS resource information element. For example, a new information element (e.g., slotOffset) can be added in the information element of the aperiodic CSI-RS resource to indicate the first information.

[0307] Alternatively, the first information can be carried in a CSI-RS resource information element. For example, the multiplexing field "periodicityAndOffset" is used to indicate the offset of the CSI-RS resource when the resource type of the CSI-RS resource is aperiodic, and is used to indicate the periodicity and offset of the CSI-RS resource when the resource type of the CSI-RS resource is periodic or semi-static.

[0308] It should be understood that the time slot in which each resource of the plurality of resources is located is an available time slot.

[0309] S802, the second device transmits the reference signal corresponding to each resource in the time slot in which each resource of the plurality of resources is located. Correspondingly, the first device receives the reference signal corresponding to each of the at least part of the plurality of resources in the time slot in which each resource of the at least part of the plurality of resources is located.

[0310] For the first device, the time slot in which each resource of the plurality of resources is located can be determined by the first device according to the first reference time slot and the offset of each resource of the plurality of resources.

[0311] The reference signal corresponding to each resource is used for channel state information measurement. The reference signal corresponding to each of the at least part of the plurality of resources is used for channel state information measurement.

[0312] In one possible implementation, the time slot in which at least one resource of the plurality of resources is located is determined according to the offset of the at least one resource and the first reference time slot.

[0313] Optionally, in the case that the target correspondence relationship is correspondence relationship 1, the time slot in which the first resource of the plurality of resources is located is determined according to the offset of the first resource and the first reference time slot, and the time slot in which the kth resource of the plurality of resources is located is determined according to the offset of the kth resource and the time slot in which the (k-1)th resource of the plurality of resources is located; wherein k is a positive integer greater than or equal to 2.

[0314] Alternatively, in the case that the target correspondence relationship is correspondence relationship 2, the time slot in which the first resource of the plurality of resources is located is determined according to the offset of the first resource and the first reference time slot, and the time slot in which the kth resource of the plurality of resources is located is determined according to the offset of the kth resource and the time slot in which the first resource of the plurality of resources is located.

[0315] Alternatively, in the case that the target correspondence relationship is correspondence relationship 3, the time slot in which each resource of the plurality of resources is located is determined according to the offset of each resource and the first reference time slot.

[0316] In the case that the offset of the resource is a time slot offset, the index of the time slot in which the kth resource of the plurality of resources is located satisfies the relationship shown in the following formula (1):

[0317] Ink=Inr+O1k; (1)

[0318] wherein Ink is the index of the time slot in which the kth resource of the plurality of resources is located, Inr is the index of the reference time slot of the kth resource of the plurality of resources, Inr is the index of the first reference time slot when k=1, and O1k is the time slot offset of the kth resource of the plurality of resources.

[0319] In the case that the offset of the resource is a time slot offset of available time slots, the index of the time slot in which the kth resource of the plurality of resources is located satisfies the relationship shown in the following formula (2) or formula (3):

[0320] Ink=Inr+S S,U +O2k; (2)

[0321] Ink=Inr+O1k′; (3)

[0322] wherein S S,Uone or more of the following: the number of time slots that cannot be used for CSI-RS resources between the kth resource in the plurality of resources and the reference time slot of the kth resource; or, the number of uplink time slots between the kth resource in the plurality of resources and the reference time slot of the kth resource; or, the number of special time slots between the kth resource in the plurality of resources and the reference time slot of the kth resource; or, the number of special time slots and uplink time slots between the kth resource in the plurality of resources and the reference time slot of the kth resource; or, the number of time slots that do not belong to the available time slots between the kth resource in the plurality of resources and the reference time slot of the kth resource. For the convenience of understanding, the following will be S S,U referred to as unavailable time slots.

[0323] O2k is the time slot offset of the kth resource in the plurality of resources, and O1k' is the available time slot offset of the kth resource in the plurality of resources.

[0324] In other words, the correspondence relationship 3 can be realized by formula (1), or by formula (2) or formula (3).

[0325] For the convenience of understanding, the following will be illustrated in the case of the offset of the resource and the target correspondence relationship.

[0326] Case 1, the offset of the resource is the time slot offset.

[0327] Case 1.1, the target correspondence relationship is correspondence relationship 1. In this case, the index of the time slot where the first resource in the plurality of resources is located is the sum of the index of the time slot where the first reference time slot is located and the offset of the first resource in the plurality of resources. The index of the time slot where the kth resource in the plurality of resources is located is the sum of the index of the time slot where the k-1th resource in the plurality of resources is located and the offset of the kth resource in the plurality of resources.

[0328] Case 1.2, the target correspondence relationship is correspondence relationship 2. The target correspondence relationship is correspondence relationship 1. In this case, the index of the time slot where the first resource in the plurality of resources is located is the sum of the index of the time slot where the first reference time slot is located and the offset of the first resource in the plurality of resources. The index of the time slot where the kth resource in the plurality of resources is located is the sum of the index of the time slot where the first resource in the plurality of resources is located and the offset of the kth resource in the plurality of resources.

[0329] Case 1.3, the target correspondence relationship is correspondence relationship 3. In this case, the index of the time slot where the first resource in the plurality of resources is located is the sum of the index of the time slot where the first reference time slot is located and the offset of the first resource in the plurality of resources. The index of the time slot where the kth resource in the plurality of resources is located is the sum of the index of the first reference time slot and the offset of the kth resource in the plurality of resources.

[0330] In case 1, the index of the time slot in which the kth resource in the plurality of resources is located satisfies the relationship shown in formula (1).

[0331] In case 2, the offset of the resource is the time slot offset of the available time slot. The following is an example in which the available time slot is a downlink time slot.

[0332] In case 2.1, the target correspondence relationship is correspondence relationship 1. In this case, the index of the time slot in which the first resource in the plurality of resources is located is the sum of the index of the time slot in which the first reference time slot is located, the offset of the first resource in the plurality of resources, and the number of unavailable time slots between the first resource in the plurality of resources and the first reference time slot. The index of the time slot in which the kth resource in the plurality of resources is located is the sum of the index of the time slot in which the k-1th resource in the plurality of resources is located, the offset of the kth resource in the plurality of resources, and the number of unavailable time slots between the kth resource in the plurality of resources and the k-1th time slot in the plurality of resources.

[0333] In case 2.2, the target correspondence relationship is correspondence relationship 2. The index of the time slot in which the first resource in the plurality of resources is located is the sum of the index of the time slot in which the first reference time slot is located, the offset of the first resource in the plurality of resources, and the sum of the unavailable time slots between the first resource in the plurality of resources and the first reference time slot. The index of the time slot in which the kth resource in the plurality of resources is located is the sum of the index of the time slot in which the k-1th resource in the plurality of resources is located, the offset of the first resource in the plurality of resources, and the sum of the unavailable time slots between the kth resource in the plurality of resources and the first time slot in the plurality of resources.

[0334] In case 2.3, the target correspondence relationship is correspondence relationship 3. In this case, the index of the time slot in which the first resource in the plurality of resources is located is the sum of the index of the time slot in which the first reference time slot is located, the offset of the first resource in the plurality of resources, and the number of unavailable time slots between the first resource in the plurality of resources and the first reference time slot. The index of the time slot in which the kth resource in the plurality of resources is located is the sum of the index of the first reference time slot, the offset of the kth resource in the plurality of resources, and the number of unavailable time slots between the kth resource in the plurality of resources and the first reference time slot.

[0335] In case 2, the index of the time slot in which the kth resource in the plurality of resources is located satisfies the relationship shown in formula (2) or formula (3).

[0336] It should be understood that in case 2, the available time slot is taken as a downlink time slot for example, and in other cases of available time slots, the determination principle of the kth resource in the plurality of resources is similar to that in case 2, which will not be described hereinafter.

[0337] In a possible implementation, the plurality of resources includes a first resource and a second resource, and in this case, S802 can include: the second device sending a first reference signal corresponding to the first resource on a first time slot and sending a second reference signal corresponding to the second resource on a second time slot. Correspondingly, the first device receives the first reference signal corresponding to the first resource on the first time slot and / or receives the second reference signal corresponding to the second resource on the second time slot.

[0338] For the first device, the first time slot is determined according to a first offset and a first reference time slot, the first resource is located in the first time slot, the second time slot is determined according to a second offset and a second reference time slot, and the second resource is located in the second time slot. The first reference signal and the second reference signal are both used for channel state information measurement.

[0339] In a case where the offset of the resource is a time slot offset, the first time slot and the second time slot both satisfy the relationship shown in formula (1).

[0340] In a case where the offset of the resource is a time slot offset of an available time slot, the first time slot and the second time slot both satisfy the relationship shown in formula (2) or formula (3).

[0341] For the first device, in a possible implementation, the first time slot is determined according to a first time slot offset and a first reference time slot, the first resource is located in the first time slot, the second time slot is determined according to a second time slot offset and a second reference time slot, the second resource is located in the second time slot, the first reference time slot is a time slot containing a trigger DCI, the second reference time slot is the first time slot, the trigger DCI is used to activate the first resource and the second resource, and the first reference signal and the second reference signal are both used for channel state information measurement.

[0342] In another possible implementation, the first time slot is determined according to a first time slot offset and a first reference time slot, the first resource is located in the first time slot, the second time slot is determined according to a second time slot offset and a second reference time slot, the second resource is located in the second time slot, the first reference time slot and the second reference time slot are both time slots containing a trigger DCI, the trigger DCI is used to activate the first resource and the second resource, and the first reference signal and the second reference signal are both used for channel state information measurement.

[0343] The method provided in the embodiments of the present application can further include S803.

[0344] S803, the first device sends a measurement result of a reference signal corresponding to at least part of the plurality of resources. Correspondingly, the second device receives the measurement result of the reference signal corresponding to at least part of the plurality of resources.

[0345] The quantity MR of at least part of the plurality of resources can be determined by the first device or indicated by the second device. Assuming that the CSI reporting configuration activated by the trigger DCI is associated with 8 CSI-RS resources, such as resource 1 to resource 8, and MR = 1, and the second device indicates that resource 3 is a first type of reference signal resource, i.e., a high priority reference signal resource, and other reference signal resources are second type of reference signal resources, i.e., normal reference signal resources, then the first device can report the measurement result of the reference signal corresponding to resource 3. If MR = 3, the measurement result reported by the first device can include the measurement result of the reference signal corresponding to any two of resource 1, resource 2, resource 4 to resource 8.

[0346] In a case where the first resource includes the first resource and the second resource, the channel state information includes measurement results of the first reference signal and the second reference signal. The first reference signal is a reference signal carried on the first resource, and the second reference signal is a reference signal carried on the second resource.

[0347] It should be understood that the measurement result of the reference signal corresponding to each of the plurality of resources can also include a measurement result of a reference signal corresponding to a third resource.

[0348] In a possible implementation, in a case where the plurality of resources include the first resource and the second resource, the first information can also be used to indicate a third offset of a third resource, the third resource being located in a third time slot. In other words, the third time slot is a time slot in which the third resource is located. The third offset is associated with the third time slot and a third reference time slot, and the third offset is used to determine the third resource. The third resource can be determined by the second device.

[0349] The third resource is a time slot in the plurality of time slots.

[0350] Optionally, the third reference time slot is the time slot containing the trigger DCI; in this way, the process of determining the third resource can be decoupled from the process of determining other resources, improving communication efficiency. Alternatively, the third reference time slot is the first time slot; in this way, the process of determining the second resource and the process of determining the third resource can be executed in parallel, and the offset of the second resource and the third resource can be smaller, which can balance the overhead and communication efficiency. Alternatively, the third reference time slot is the second time slot; in this way, the third offset can be smaller, the information used to indicate the second offset can be reduced, and the overhead of the first resource can be reduced.

[0351] The following illustrates the relationship between the first offset, the second offset, and the third offset, and the correspondence between the first resource to the third resource and the first reference time slot to the third reference time slot, in combination with the target correspondence.

[0352] Assuming that the time slot distribution in time slot r to time slot r+15 is as follows Figure 10As shown in (a) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 1, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 1. The second reference slot is the slot r+3, and the second offset is the offset between the slot r+5 and the slot r+3, i.e. 2. The third reference slot is the slot r+5, and the third offset is the offset between the slot r+9 and the slot r+5, i.e. 2. Figure 10 As shown in (b) of FIG. 13, if the offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 2, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 1. The second reference slot is the slot r+3, and the second offset is the offset between the slot r+5 and the slot r+3, i.e. 2. The third reference slot is the slot r+3, and the third offset is the offset between the slot r+9 and the slot r+3, i.e. 4.

[0353] As shown in (c) of FIG. 13, if the offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 3, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 1. The second reference slot is the slot r, and the second offset is the offset between the slot r+5 and the slot r, i.e. 3. The third reference slot is the slot r, and the third offset is the offset between the slot r+9 and the slot r, i.e. 5. Figure 10 As shown in (d) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 1, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r+3, and the second offset is the offset between the slot r+5 and the slot r+3, i.e. 2. The third reference slot is the slot r+5, and the third offset is the offset between the slot r+9 and the slot r+5, i.e. 4. As shown in (e) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 2, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r+3, and the second offset is the offset between the slot r+5 and the slot r+3, i.e. 2. The third reference slot is the slot r+3, and the third offset is the offset between the slot r+9 and the slot r+3, i.e. 4.

[0354] As shown in (f) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 3, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r, and the second offset is the offset between the slot r+5 and the slot r, i.e. 4. The third reference slot is the slot r, and the third offset is the offset between the slot r+9 and the slot r, i.e. 5. Figure 10 As shown in (g) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 1, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r+3, and the second offset is the offset between the slot r+5 and the slot r+3, i.e. 2. The third reference slot is the slot r+5, and the third offset is the offset between the slot r+9 and the slot r+5, i.e. 4. As shown in (h) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 2, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r+3, and the second offset is the offset between the slot r+5 and the slot r+3, i.e. 2. The third reference slot is the slot r+3, and the third offset is the offset between the slot r+9 and the slot r+3, i.e. 4.

[0355] As shown in (i) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 3, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r, and the second offset is the offset between the slot r+5 and the slot r, i.e. 4. The third reference slot is the slot r, and the third offset is the offset between the slot r+9 and the slot r, i.e. 5. Figure 10 As shown in (j) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 1, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r+3, and the second offset is the offset between the slot r+5 and the slot r+3, i.e. 2. The third reference slot is the slot r+5, and the third offset is the offset between the slot r+9 and the slot r+5, i.e. 4. As shown in (k) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 2, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r+3, and the second offset is the offset between the slot r+5 and the slot r+3, i.e. 2. The third reference slot is the slot r+3, and the third offset is the offset between the slot r+9 and the slot r+3, i.e. 4.

[0356] As shown in (l) of FIG. 13, if the slot offset is the available slot offset, in the case that the target correspondence relationship is the correspondence relationship 3, the first reference slot is the slot r, and the first offset is the offset between the slot r+3 and the slot r, i.e. 3. The second reference slot is the slot r, and the second offset is the offset between the slot r+5 and the slot r, i.e. 4. The third reference slot is the slot r, and the third offset is the offset between the slot r+9 and the slot r, i.e. 5. Figure 10As shown in (e), if the time slot offset is a time slot offset, then in the case of the target correspondence as in correspondence 2, the first reference time slot is time slot r, and the first offset is the offset between time slot r+3 and time slot r, i.e., 3. The second reference time slot is time slot r+3, and the second offset is the offset between time slot r+5 and time slot r+3, i.e., 2. The third reference time slot is time slot r+3, and the third offset is the offset between time slot r+9 and time slot r+3, i.e., 6.

[0357] like Figure 8 As shown in (f), if the time slot offset is a time slot offset, then in the case of the target correspondence as in correspondence 3, the first reference time slot is time slot r, and the first offset is the offset between time slot r+3 and time slot r, i.e., 3. The second reference time slot is time slot r, and the second offset is the offset between time slot r+5 and time slot r, i.e., 5. The third reference time slot is time slot r, and the third offset is the offset between time slot r+9 and time slot r, i.e., 9.

[0358] Optionally, the third resource can reuse the offset of the first resource, that is, the third offset is the same as the first offset. Alternatively, the third resource can reuse the offset of the second resource, that is, the third offset is the same as the second offset.

[0359] In this way, the overhead of indicating the first information can be reduced. It is understandable that the third offset can be implemented through pre-configuration.

[0360] In another possible implementation, the first information is also used to indicate whether the time slot where the third resource is located is the first time slot or the second time slot. In other words, the third resource is in the same time slot as the first resource, or the third resource is in the same time slot as the second resource. That is, the third resource can reuse the first or second time slot, thus reducing the processing complexity of the first device. Alternatively, the rules for determining the time slot where the third resource is located can be pre-configured in the first and second devices. For example, the rules for determining the time slot where the third resource is located include: the time slot where the third resource is located is the same as the time slot where the first resource is located, or the time slot where the third resource is located is the same as the time slot where the second resource is located. The rules for determining the time slot where the third resource is located can be agreed upon by the protocol, or in other words, the time slot where the third resource is located can be agreed upon by the protocol.

[0361] In one possible implementation, the third resource and the second resource belong to the same resource set. In this case, if the first resource and the second resource belong to the same resource set, then the first resource, the second resource, and the third resource all belong to the same resource set. For example, the first resource to the third resource are all resources in the same CSI-RS resource set, or the same CSI-IM resource set, or the same channel state information measurement resource set, or the same interference measurement resource set, or the same CSI-SSB resource set.

[0362] Alternatively, the first resource and the second resource belong to the first resource set, the third resource belongs to the second resource set, and the third resource is associated with at least one of the first resource and the second resource.

[0363] If the first information is also used to indicate the offset of the third resource or the third time slot where the third resource is located, Figure 8 The provided method may also include S804a.

[0364] S804a, the second device sends a third reference signal to the first device in the third time slot. Correspondingly, the first device receives the third reference signal in the third time slot.

[0365] The third reference signal is the reference signal corresponding to the third resource. For the first device, the third resource is determined based on the third offset and the third reference time slot. For details on how the first device determines the third resource, please refer to the relevant introduction on determining multiple resources by the first device; further details will not be provided here.

[0366] exist Figure 8 The provided method also includes, in the case of S804a, the channel state information may also include a reference signal carried on a third resource, such as the measurement result of the third reference signal.

[0367] In this embodiment of the application, the multiple resources may further include other resources. The first information may also be used to indicate the offset of each of the other resources. Each of the other resources may use the first time slot, the second time slot, or the time slot containing the preceding resource as its reference time slot. For example, assuming the first information is also used to indicate the offset of the fourth resource, then the fourth resource may use the first time slot, the second time slot, or the third resource as its reference time slot.

[0368] In one possible implementation, where multiple resources comprise the same resource set, such as resources in a first resource set, the first information is also used to indicate the offset of each resource in a second resource set.

[0369] The second resource set includes at least one resource. For example, if the third resource belongs to a different resource set than the first and second resources, and multiple resources do not include the third resource, the second resource set may include the third resource. The second resource set may also include more resources. The second resource set differs from the first resource set. Resources in the second resource set can be used for interference measurements. For example, if the first resource set is the CSI-RS resource set, then the second resource set may be the CSI-IM resource set.

[0370] Optionally, the time slot of each resource in the second resource set is related to the offset of each resource in the second resource set and the first reference position.

[0371] In this case, the time slot of each resource in the second resource set is determined based on the offset of each resource in the second resource set and the reference time slot of that resource.

[0372] Optionally, the reference time slot of the first resource in the second resource set can be the time slot of the Kth resource among multiple resources, and the time slot of the sth resource in the second resource set can be the time slot of the (s-1)th resource in the second resource set, where s is a positive integer greater than or equal to 2, and s is less than or equal to the total number of resources in the second resource set.

[0373] Optionally, the resources in the second resource set correspond one-to-one with the resources in the first resource set, and the offset of each resource in the second resource set is the offset of the resource in the first resource set corresponding to each resource in the second resource set. For example, the first resource set includes resources 1 to 3, and the second resource set includes resources 4 to 6, where resource 4 corresponds to resource 1, resource 5 corresponds to resource 2, and resource 6 corresponds to resource 3. Then, the offset of resource 4 corresponds to the offset of resource 1, the offset of resource 5 corresponds to the offset of resource 2, and the offset of resource 6 corresponds to the offset of resource 3.

[0374] Alternatively, the offset of each resource in the second resource set is the same as the offset of the same resource in the first resource set.

[0375] For example, the first resource set includes resources 1 to 3, and the second resource set includes resources 4 to 6, wherein the offsets of resources 4 to 6 are all the same as the offset of resource 1.

[0376] Optionally, the number of resources in the second resource set is less than the number of resources in the first resource set, and the offset of each resource in the second resource set is the offset of a certain resource in the second resource set shown.

[0377] For example, the first resource set includes resources 1 to 3, and the second resource set includes resource 4. In this case, the offset of resource 4 is the resource with the smallest index, the largest index, the highest measurement priority, or the resource determined according to the criteria agreed upon in the protocol among resources 1 to 3.

[0378] In this embodiment of the application, the correspondence between the offset of each resource in the second resource set, the reference time slot of each resource, and the time slot where each resource is located can be pre-configured or implemented through protocol agreement.

[0379] In another possible implementation, the first information is also used to indicate the time slot in which the resources in the second resource set are located, and the time slot in which the resources in the second resource set are located is the same as the time slot in which any resource in the first resource set is located.

[0380] For example, suppose the first resource set includes resources 1 to 3, where resources 1 and 3 each correspond to a time slot. Then, the first information can indicate that the time slot where the resource in the second resource set is located is the time slot where resource 3 is located.

[0381] It is understandable that the time slot of a resource in the second resource set is the same as the time slot of any resource in the first resource set, or it can be preset, such as by predefining through a protocol.

[0382] In cases where the first information is also used to indicate the offset of each resource in the second resource set, or to indicate the offset of each resource in the second resource set, Figure 8 The provided method may also include S804b:

[0383] S804b, the second device transmits a reference signal corresponding to each resource in the second resource set in the time slot where each resource in the second resource set resides. Correspondingly, the first device receives the reference signals corresponding to at least some of the resources in the second resource set in the time slots where at least some of the resources in the second resource set reside.

[0384] The second resource set differs from the first resource set. For example, if the first resource set is a CSI-RS resource set used for channel measurement, then the second resource set can be a resource set used for interference measurement, such as a CSI-IM resource set.

[0385] It should be understood that in the embodiments of this application, the order and number of steps S802 and S803 are used to distinguish each step, and do not represent the order of execution of the steps. In addition, the execution order between S802, S804a and S804b is not limited.

[0386] based on Figure 11The provided method allows a second device to indicate the offset of each of multiple resources using first information, and to transmit a reference signal corresponding to each resource in the time slot where each resource is located. The first device receives the reference signal for channel state information measurement in the time slot determined according to the first information. The first information can indicate the offset of different resources respectively. In this way, in one case, the first device can determine multiple resources in different time slots based on the offset of different resources, thereby receiving reference signals in multiple time slots, assisting in the measurement of channel state information for multiple beams, and can be applied to more scenarios.

[0387] In one possible embodiment, the offset of the first resource among the K resources can be the offset between the time slot containing the first resource and the time slot containing the DCI trigger. The offsets of the other resources among the K resources (excluding the first resource) are the offsets between the time slot containing the resource and the time slot containing the resource preceding it. In this case, the method provided by the embodiments of this application can be as follows: Figure 8 As shown:

[0388] S1101, the second device sends the first information. Correspondingly, the first device receives the first information.

[0389] The first information is used to indicate the offset of each of the multiple first resources; wherein, the offset of the first first resource in the multiple first resources corresponds to the time slot where the first resource is located and the time slot containing the trigger DCI, the offset of the kth first resource in the multiple first resources corresponds to the time slot where the kth first resource is located and the time slot where the (k-1)th first resource is located, the trigger DCI is used to activate the multiple first resources, k is an integer greater than or equal to 2, and k is less than or equal to K, where K is the number of resources in the multiple resources.

[0390] In one possible implementation, multiple first resources belong to a first resource set. That is, the resources in the multiple first resources are all resources in the first resource set. For example, the multiple first resources may include all resources in the first resource set.

[0391] The first resource set can be any one of the following: CSI-RS resource set, CSI-IM resource set, interference measurement resource set, channel measurement resource set, or SSB resource set. For details on the implementation of the channel state information reference signal resource set, interference measurement resource set, channel measurement resource set, and SSB resource set, please refer to [reference needed]. Figure 8 The relevant descriptions in the provided methods are provided. It should be understood that the first resource set listed here is for illustrative purposes only. In actual implementation, the first resource set can also be other resource sets configured in the channel measurement configuration, which will not be elaborated further.

[0392] In another possible implementation, the multiple first resources include resources from multiple resource sets. For example, the multiple first resource sets include resources from a first resource set and resources from a second resource set. The second resource set can be any one of the following: a channel state information reference signal resource set, an interference measurement resource set, or a channel measurement resource set, and the second resource set is different from the first resource set.

[0393] In one possible implementation, the offset is a time slot offset, or a time slot offset of available time slots.

[0394] If the offset is a timeslot offset, then the offset of each of the multiple first resources is a timeslot offset; if the offset is a timeslot offset of an available timeslot, then the offset of each of the multiple first resources is a timeslot offset of an available timeslot.

[0395] In one possible implementation, available time slots are time slots that satisfy one or more of the following: a time slot in which downlink symbols and / or flexible symbols satisfy the time-domain position of at least one reference signal resource within the reference signal resource set; or, a time slot with a time interval greater than or equal to a first threshold between it and a time slot containing a trigger DCI; or, a time slot in which all symbols are downlink symbols; or, a time slot not occupied by a synchronization signal and physical broadcast channel block (SSB); or, a time slot not occupied by the Remaining Minimum System Information (RMSI); or, a non-uplink time slot; or, a time slot in which the number of downlink symbols and / or flexible symbols available for reference signal transmission is greater than or equal to N. Alternatively, a time slot in which the number of symbols available for downlink transmission is greater than or equal to N, where N is a positive integer. For implementation details of available time slots, please refer to [reference needed]. Figure 8 The details regarding the available time slots in the provided methods will not be elaborated upon.

[0396] S1102, the second device transmits a reference signal corresponding to each resource in the second resource set in the time slot where each of the plurality of first resources is located. Correspondingly, the first device receives reference signals corresponding to at least a portion of the first resources in the second resource set in the time slots where at least a portion of the plurality of first resources are located.

[0397] The time slot of the first first resource among multiple first resources is determined based on the offset of the first first resource and the time slot containing the trigger DCI. The time slot of the kth first resource among multiple first resources is determined based on the offset of the kth first resource and the time slot where the (k-1)th first resource is located. The trigger DCI is used to activate multiple first resources, and the reference signal is used for channel state information measurement.

[0398] In other words, the first first resource among multiple first resources uses the time slot containing the trigger DCI as its reference time slot. The kth first resource among multiple first resources uses the time slot containing the (k-1)th first resource among multiple first resources as its reference time slot. For specific implementation details, please refer to [link / reference]. Figure 11 The relevant descriptions of correspondence 3 in the provided methods will not be repeated here.

[0399] For details on the implementation of S1102, please refer to the relevant introduction of S802, or refer to the relevant introductions of S802 and S804a.

[0400] In one possible implementation, Figure 11 The provided methods may also include:

[0401] S1103, the first device transmits the measurement result of the reference signal corresponding to at least one of the plurality of first resources. Correspondingly, the second device receives the measurement result of the reference signal corresponding to at least one of the plurality of first resources.

[0402] In one possible implementation, the first information is also used to indicate the offset of at least one second resource.

[0403] At least one second resource can be a resource in a set of resources configured in the reference signal measurement configuration. At least one second resource can belong to the same set of resources, or at least one second resource can belong to different sets of resources.

[0404] In one possible implementation, at least one second resource belongs to the same resource set as multiple first resources; or, multiple first resources belong to a first resource set, at least one second resource belongs to a second resource set, and the second resource in at least one second resource is associated with multiple first resources.

[0405] In one possible implementation, at least one second resource in a second resource corresponds one-to-one with a first resource in a plurality of first resources, and the offset of the second resource is the offset of the first resource corresponding to the second resource.

[0406] In one possible implementation, the offset of the second resource is the offset of any one of the multiple first resources.

[0407] As an example, the first resources include resources 1 to 4, and the offset of the second resource can be any one of resources 1 to 4, such as the offset of resource 3.

[0408] In this scenario, the offset of the second resource can be pre-configured to be the offset of which of the multiple first resources. Alternatively, one of the multiple first resources can be designated as the default resource, and the second resource can be the offset of that default resource. For example, the offset of the second resource can be pre-configured to be the offset of the first of the multiple first resources.

[0409] Alternatively, the second device may indicate to the first device that the offset of the second resource is the offset of which of the plurality of first resources.

[0410] In one possible implementation, the first information is also used to indicate the time slot where the second resource is located, which is any one of the multiple first resources.

[0411] As an example, the first resources include resources 1 to 4, and the time slot where the second resource is located can be any one of the time slots where resources 1 to 4 are located, such as the time slot where resource 3 is located.

[0412] based on Figure 12 The provided method allows a second device to indicate the offset of each of a plurality of first resources using first information and to transmit reference signals on the plurality of first resources. The first device receives the reference signals for channel state information measurement in a time slot determined according to the first information. The first information may indicate the offsets of different first resources, such as the offset of the first first resource and the offset of the Kth first resource. In this way, in one case, the first device can determine multiple first resources in different time slots based on the offsets of different first resources, thereby receiving reference signals in multiple time slots, assisting in the measurement of channel state information for multiple beams, and applicable to more scenarios.

[0413] In another embodiment of this application, an auxiliary channel measurement method is also provided. In this method, a second device can indicate to a first device the relative positional relationship between resources in a resource set, and the position of at least one resource in the resource set. The first device can determine the time slot of each resource based on the relative positional relationship between resources in the resource set and the position of at least one resource in the resource set, thereby performing channel state information measurement. The following is combined with... Figure 12 The provided auxiliary channel measurement method is explained, such as... Figure 13 As shown, the method for auxiliary channel measurement includes:

[0414] S1201, the second device sends the first information. Correspondingly, the first device receives the first information.

[0415] The first information is used to indicate the time slot where the first resource in the K resources is located, and the first information is used to indicate the relationship between the time slots where each resource in the K resources is located. K is a positive integer greater than or equal to 2, such as K = 2, 3, 4, 5, ...

[0416] In this embodiment, the time slot where the first resource in the K resources indicated by the first information is located, and the relationship between the time slots where each of the K resources is located, can also be called an offset pattern. In other words, the first information is used to indicate the offset pattern. The offset pattern can also be named by other names, such as offset pattern, offset design, etc., which will not be elaborated here.

[0417] In this embodiment, the K resources may belong to the resource set configured by the second device for the first device. The K resources may include two or more resources. Optionally, the K resources may include one or more of the following resources: CSI-RS resources, CSI-IM resources, multiple channel measurement resources, interference measurement resources, or CSI-SSB resources.

[0418] For example, the K resources may include a first resource and a second resource. In this case, the first information is used to indicate the time slot where the first resource is located, and the relationship between the time slot where the first resource is located and the time slot where the second resource is located.

[0419] The first resource is one of the K resources. For example, the first resource can be the first resource among the K resources, or the resource with the smallest resource index among the K resources, or the resource with the largest resource index among the K resources, or the resource with the earliest time-domain position among the K resources, or the last resource among the K resources, or the resource with the latest time-domain position among the K resources. The time-domain position of the second resource can be before the time-domain position of the first resource, or the time-domain position of the second resource can be after the first resource. In the embodiments of this application, the second device can determine the K resources according to the resources needed to transmit the reference signal. For example, the K resources may include resources needed to transmit the reference signal.

[0420] The time slot containing the first resource can also be understood as the time slot including the first resource, or the time slot whose time domain location includes the time domain location of the first resource. For example, if the first resource is the k-th resource out of K resources, the time slot containing the first resource is the same as the time slot containing the k-th resource out of K resources. For instance, if the first resource is the 1st resource out of K resources (i.e., k=1), the time slot containing the first resource is the same as the time slot containing the 1st resource out of K resources. Or, if the first resource is the last resource out of K resources (i.e., k=K), the time slot containing the first resource is the same as the time slot containing the last resource out of K resources. The time slot containing any one of the K resources is the same as the time slot containing the first resource.

[0421] In scenarios where CSI is reported non-periodically, optionally, the time slot where the first resource is located refers to the position of the time slot where the first resource is located relative to the time slot containing the triggering DCI. In other words, the time slot where the first resource is located is the time slot relative to the triggering DCI. In this case, the first information indicating the time slot where the first resource is located may include: the first information indicating the offset of the time slot where the first resource is located relative to the time slot containing the triggering DCI. Alternatively, optionally, the time slot where the first resource is located refers to the position of the first resource in the time slot within the target time slot set. In other words, the time slot where the first resource is located is the time slot within the target time slot set, such as the start time slot and end time slot of the target time slot set. In this case, the first information indicating the time slot where the first resource is located may include: the first information indicating the relative time slot position of the time slot where the first resource is located within the target time slot set.

[0422] The target time slot set can be achieved through the following means:

[0423] Case 3: For the second device, the target time slot set can be determined based on the time slot of each of the K resources.

[0424] Case 3.1: The target time slot set refers to the set including the first time slot containing one of the K resources, the last time slot containing one of the K resources, and one or more time slots between the first and last time slots containing the K resources. Alternatively, the target time slot set includes the period from the first time slot containing one of the K resources to the last time slot containing one of the K resources. It should be understood that the time slots in the target time slot set are continuous, and the target time slot set may include one or more of the following: downlink time slots, uplink time slots, special time slots, or flexible time slots.

[0425] For example, if the starting time slot of a resource in K resources is time slot 1 and the ending time slot is time slot 5, and time slot 1 is a downlink time slot, time slot 2 is a special time slot, time slot 3 is an uplink time slot, time slot 4 is a downlink time slot, and time slot 5 is a downlink time slot, then the target time slot set can be obtained, which includes time slot 1, time slot 5, and all time slots from time slot 1 to time slot 5. That is, the target time slot set can be understood as {time slot 1, time slot 2, time slot 3, time slot 4, time slot 5}.

[0426] Case 3.2: The target time slot set refers to the set including the first available time slot of the K resources, the last available time slot of the K resources, and one or more available time slots between the first available time slot of the K resources and the last available time slot of the K resources. In this case, the time slots in the target time slot set can be consecutive or non-consecutive.

[0427] Optionally, available time slots may be time slots that satisfy one or more of the following: A time slot where downlink symbols and / or flexible symbols satisfy the time domain position of at least one reference signal resource within the reference signal resource set, or a time slot that meets the time domain resource requirement. Alternatively, a time slot where the time interval between a time slot containing a trigger DCI meets the time requirement (the time requirement is related to terminal capabilities, or predefined by the protocol, or related to the processing time required for DCI demodulation). Alternatively, a time slot where all symbols are downlink symbols. Alternatively, a time slot not occupied by synchronization signals and physical broadcast channel blocks (SSBs). Alternatively, a time slot not occupied by the Remaining Minimum System Information (RMSI). Alternatively, a non-uplink time slot. Alternatively, a time slot with a number of downlink symbols and / or flexible symbols available for reference signal transmission greater than or equal to N. Alternatively, a time slot with a number of symbols available for downlink transmission greater than or equal to N, where N is a positive integer, and the value of N is related to the number of ports contained in at least one reference signal resource within the reference signal resource set, or predefined by the protocol. A reference signal resource set is a collection of resources consisting of a reference signal resource, such as a CSI-RS resource, a CSI-IM resource, multiple channel measurement resources, interference measurement resources, or a CSI-SSB resource.

[0428] As an example, a time slot whose time interval with the time slot containing the trigger DCI meets the time requirement can be a time slot whose time interval with the time slot containing the trigger DCI is greater than or equal to a first threshold. The first threshold is a duration threshold, which is related to the terminal capability, or predefined by the protocol, or related to the processing time required for DCI demodulation.

[0429] In this embodiment, available time slots can be downlink time slots, special time slots, or flexible time slots. Specifically, time slots not occupied by synchronization signals and physical broadcast channel blocks (SSBs) can refer to downlink time slots, special time slots, or flexible time slots not occupied by SSBs. Time slots not occupied by residual minimum system information (RMSIs) can refer to downlink time slots, special time slots, or flexible time slots not occupied by residual minimum system information (RMSIs). Non-uplink time slots can be downlink time slots, special time slots, or flexible time slots.

[0430] For example, assuming the downlink time slot is the available time slot, the starting time slot of the time slot containing the K resources is time slot 1, and the ending time slot is time slot 5, and time slot 1 is the downlink time slot, time slot 2 is the special time slot, time slot 3 is the uplink time slot, time slot 4 is the downlink time slot, and time slot 5 is the downlink time slot, the target time slot set includes time slot 1, time slot 5, and the downlink time slots from time slot 1 to time slot 5, which can be understood as the target time slot set = {time slot 1, time slot 4, time slot 5}.

[0431] For example, suppose that downlink time slots and special time slots are available time slots, and the starting time slot of the time slot containing the K resources is time slot 1 and the ending time slot is time slot 5, and time slot 1 is a downlink time slot, time slot 2 is a special time slot, time slot 3 is an uplink time slot, time slot 4 is a downlink time slot, and time slot 5 is a downlink time slot, then the target time slot set includes time slot 1, time slot 5, and the downlink time slots and special time slots from time slot 1 to time slot 5. That is, it can be understood as the target time slot set = {time slot 1, time slot 2, time slot 4, time slot 5}.

[0432] Case 4: For the second device, the target time slot set can be determined based on the time slot containing the trigger DCI and K resources.

[0433] Case 4.1: The target time slot set refers to the time slot containing the DCI trigger, the last time slot containing one of the K resources, and the time slots between the DCI trigger time slot and the last time slot containing one of the K resources. Alternatively, the target time slot set includes the time slot containing the DCI trigger to the last time slot containing one of the K resources. In this case, all time slots in the target time slot set are consecutive. The target time slot set can include one or more of the following: downlink time slots, uplink time slots, special time slots, or flexible real-time slots. For example, the time slot containing the DCI trigger is time slot 0, the last time slot occupied by one of the K resources is time slot 5, and time slot 0 is a downlink time slot, time slot 1 is a downlink time slot, time slot 2 is a special time slot, time slot 3 is an uplink time slot, time slot 4 is a downlink time slot, and time slot 5 is a downlink time slot. Thus, the target time slot set can be one or more of the following:

[0434] For example, the target time slot set includes time slot 0, time slot 5, and all time slots from time slot 0 to the end time slot 5, which can be understood as the target time slot set = {time slot 0, time slot 1, time slot 2, time slot 3, time slot 4, time slot 5}.

[0435] Case 4.2: The target time slot set refers to the set of available time slots that include the available time slot that triggers DCI, the last available time slot containing one of the K resources, and the time slots between the available time slot that triggers DCI and the last available time slot containing one of the K resources. In this case, the time slots in the target time slot set can be either consecutive or non-consecutive.

[0436] For example, assuming the downlink time slot is the available time slot, the time slot containing the DCI trigger is time slot 0, and the end time slot among the time slots occupied by the K resources is time slot 5, and time slot 0 is the downlink time slot, time slot 1 is the downlink time slot, time slot 2 is the special time slot, time slot 3 is the uplink time slot, time slot 4 is the downlink time slot, and time slot 5 is the downlink time slot, the target time slot set includes time slot 0, time slot 5, and the downlink time slots from time slot 0 to time slot 5, which can be understood as the target time slot set = {time slot 0, time slot 1, time slot 4, time slot 5}.

[0437] For example, suppose the downlink time slot and the special time slot are available time slots, the time slot containing the DCI trigger is time slot 0, the end time slot among the time slots occupied by the K resources is time slot 5, and time slot 0 is a downlink time slot, time slot 1 is a downlink time slot, time slot 2 is a special time slot, time slot 3 is an uplink time slot, time slot 4 is a downlink time slot, and time slot 5 is a downlink time slot. The target time slot set includes time slot 0, time slot 5, and the downlink time slots and special time slots from time slot 0 to time slot 5. That is, it can be understood as the target time slot set = {time slot 0, time slot 1, time slot 2, time slot 4, time slot 5}.

[0438] In this embodiment of the application, the target time slot set can be determined by agreement, either based on K resources or based on the time slot that triggers DCI and K resources.

[0439] The relationship between the time slots of each of the K resources can refer to the relative positional relationship between the time slots of each of the K resources. In the embodiments of this application, the first information can directly indicate the relationship between the time slots of each of the K resources. Alternatively, the first information can indirectly indicate the relationship between the time slots of each of the K resources, such as the first information may include information used to determine the relationship between the time slots of each of the K resources in conjunction with the agreed content of the protocol.

[0440] When the time slot containing the first resource refers to the time slot containing the trigger DCI, the following examples, using methods 1 to 6, illustrate the principle of how the first information indicates the relationship between the time slots containing each of the K resources. It should be understood that the relationship between the time slots containing each of the K resources indicated by the first information can be implemented using one of methods 1 to 6. In one possible implementation, the relationship between the time slots containing each of the K resources indicated by the first information may include: the position of the time slot containing each of the K resources within the target time slot set.

[0441] Method 1:

[0442] In case 3.1 or case 4.1, the relationship between the time slots of each of the K resources indicated by the first information may include: the position of the time slot of each of the K resources in the target time slot set.

[0443] In one possible implementation, the relationship between the time slots of each of the K resources indicated by the first information may further include: the first information indicating the number of time slots included in the target time slot set. For example, the first indication information may include a value representing the number of time slots included in the target time slot set. Alternatively, multiple candidate time slot numbers can be agreed upon through a protocol, with the number of time slots included in the target time slot set being one of the candidate numbers. The first information can indicate the number of time slots included in the target time slot set by indicating the identifier or index corresponding to the candidate time slot numbers.

[0444] In another possible implementation, the number of time slots in the target time slot set can be agreed upon through a protocol. For example, the possible values ​​for the number of time slots included in a target time slot set can be agreed upon through a protocol. In this case, the first information does not need to indicate the number of time slots included in the target time slot set.

[0445] Optionally, the number of bits b in the first information used to indicate the position of the time slot of each of the K resources in the target time slot set can satisfy the relationship shown in the following formula (4):

[0446]

[0447] Where W is the number of time slots contained in the target time slot set, and W is a positive integer. This indicates taking the value upwards.

[0448] If the target time slot set contains 5 time slots, then the number of bits... Bit value 000 represents the first time slot in the target time slot set, bit value 001 represents the second time slot in the target time slot set, bit value 010 represents the third time slot in the target time slot set, bit value 011 represents the fourth time slot in the target time slot set, and bit value 100 represents the fifth time slot in the target time slot set. It should be understood that the time slot represented by each bit value here is only for illustrative purposes.

[0449] Alternatively, the first information may use a bitmap to indicate the position of each of the K resources' time slots within the target time slot set. In this case, each of the K resources can correspond to a bitmap, the number of bits in which the bitmap contains the same number of time slots as the target time slot set, and each bit in the bitmap corresponds to a time slot in the target time slot set. Figure 8 As shown, assuming the target time slot set includes 5 time slots and the K resources include 3 resources (resources 1 to 3), in this case, the bitmap corresponding to each of the K resources is 5 bits, and the position of the time slots containing the 3 resources in the target time slot set can be represented by 15 bits. In the bitmap corresponding to a resource, the w-th time slot in the target time slot set corresponds to the w-th bit in the bitmap, where "1" indicates the time slot containing the resource and "0" indicates the time slot not containing the resource. Referring to case 3.1, if resource 1 is located in the first time slot of the target time slot set, the bitmap corresponding to resource 1 is "10000". If resource 2 is located in the first time slot of the target time slot set, the bitmap corresponding to resource 2 is "10000". If resource 3 is located in the fifth time slot of the target time slot set, the bitmap corresponding to resource 3 is "00001". w is a positive integer, and w is less than or equal to W.

[0450] The above-described method 1 is for illustrative purposes only. In actual implementation, method 1 can have other possible variations. For example, the first information used to indicate the relationship between the time slots of each of the K resources can include: the first information used to indicate the positional relationship between the time slot of each of the K resources other than the first resource and the time slot of the first resource. For instance, suppose there are three resources, including the first resource and resources 1 to 3, where resource 2 is in the same time slot as resource 1, and resource 3 is in the fourth time slot after resource 1. In this case, the first information can indicate that resource 1 and resource 2 are in the same time slot, and resource 3 is in the fourth time slot after resource 1.

[0451] It should be understood that the implementation of case 3.2 is similar to that of case 3.1, and will not be elaborated further.

[0452] Method 2:

[0453] In case 3.2 or case 4.2, the first information is used to indicate the relationship between the time slots of each of the K resources, and may include: the first information is used to indicate the position of the available time slot of each of the K resources in the available time slots of the target time slot set.

[0454] The definition of available time slots can be found above. Figure 14 The details regarding the available time slots in the provided methods will not be elaborated upon.

[0455] In this case, the implementation principle of the relationship between the time slots of each of the K resources indicated by the first information is similar to that in Method 1. The difference is that the time slot interval between the time slots of the two resources is replaced with the number of available time slots between the time slots of the two resources, and the number of time slots in the target time slot set is replaced with the number of available time slots in the target time slot set. For example, if each available time slot in the K resources corresponds to one bit, in this case, the number of bits in the bit map is the same as the number of available time slots in the target time slot set. The following example illustrates the first information using downlink time slots as an example. Figure 15 As shown, assuming the target time slot set includes 5 time slots, where time slots 1, 4, and 5 are available, and the K resources include 3 resources (resources 1 to 3), if resource 1 is located in time slot v+5, resource 2 in time slot v+3, and resource 3 in time slot v+9, then the bitmap corresponding to each of the K resources is 5 bits, and the position of the time slot containing each resource in the target time slot set can be represented by 15 bits. In the bitmap corresponding to a resource, the w-th time slot in the target time slot set corresponds to the w-th bit in the bitmap, where "1" indicates the time slot containing the resource and "0" indicates a time slot not containing the resource. Referring to case 1.2, if resource 1 is located in the 1st time slot of the target time slot set, then the bitmap corresponding to resource 1 is "100". If resource 2 is located in the first time slot of the target time slot set, then the bit map corresponding to resource 2 is "100". If resource 3 is located in the fifth time slot of the target time slot set, then the bit map corresponding to resource 3 is "001".

[0456] It should be understood that the implementation of Case 2.2 is similar to that of Case 1.1, and will not be elaborated further.

[0457] Method 3:

[0458] In case 3.1 or case 4.1, in one possible implementation, the first information is used to indicate the relationship between the time slots in which each of the K resources is located, and may include: the first information indicating the number of time slots contained in the target time slot set, and each of the K resources being located in an available time slot, and each of the K resources being located in a different time slot.

[0459] In this scenario, a predefined rule can be used, such as a protocol predefinition, to determine the time slots in the target time slot set for each of the K resources. Each of the K resources is located in an available time slot. This can be understood as the first information implicitly indicating the relationship between the time slots occupied by each of the K resources. As an example, the rule for resources in the K resources to occupy time slots in the target time slot set could include: the time slot occupied by a resource in the K resources is an available time slot, and the m-th resource in the K resources occupies the m-th time slot in the available time slots of the target time slot set. It should be understood that this rule is only illustrative; in actual implementation, other possible rules may exist, provided that each first resource occupies one available time slot in the target time slot set, and different resources in the first resource occupy different time slots.

[0460] The principle behind the first information indicating the number of time slots contained in the target time slot set can be found in the relevant introduction in Method 1.

[0461] The following example illustrates the principle of the relationship between the time slots of each of the K resources indicated by the first information in Method 3.

[0462] Assume there are K resources, including resources 1 to 3 (a total of 3 resources), and the available time slots are downlink time slots, such as... Figure 15 As shown, if in time slots v to v+15, resource 1 is located in time slot v+5, resource 2 is located in time slot v+8, and resource 3 is located in time slot v+9, it can be seen that resource 2 is located in the third time slot after the time slot where resource 1 is located, and resource 3 is located in the fourth time slot after the time slot where resource 1 is located. In this case, the length of the target time slot set is 5.

[0463] It should be understood that in Method 3, the location of each of the K resources in an available time slot can also be agreed upon through the protocol. The first information is also used to indicate the number of time slots included in the target time slot set. In this case, it can be understood that the first information indirectly indicates the relationship between the time slots where each of the K resources resides.

[0464] Method 4:

[0465] In cases 32 or 4.2, the first information is used to indicate the relationship between the time slots occupied by each of the K resources. This information may include: the first information indicating the number of available time slots in the target time slot set, and that each of the K resources is located in one available time slot, with each resource occupying a different time slot. The number of available time slots in the target time slot set can also be understood as the number of resources occupied by the resources among the K resources.

[0466] The principle behind the first information indicating the number of time slots contained in the target time slot set can be found in the relevant introduction in Method 1.

[0467] In Method 4, the implementation principle of the relationship between the time slots of each of the K resources indicated by the first information is similar to that in Method 3. The difference is that the number of time slots contained in the target time slot set in the first information is replaced by the number of available time slots in the target time slot set.

[0468] Assume there are K resources, including three resources from resource 1 to resource 3, and the available time slots are the unused downlink time slots, such as... Figure 16 As shown, resource 2 is located in the third time slot after resource 1, and resource 3 is located in the fourth time slot after resource 1. In this case, the number of available time slots in the target time slot set is 3.

[0469] It should be understood that in Method 4, the location of each of the K resources in an available time slot can also be agreed upon through the protocol. The first information is also used to indicate the number of available time slots contained in the target time slot set. In this case, it can be understood that the first information indirectly indicates the relationship between the time slots where each of the K resources resides.

[0470] Method 5:

[0471] In one possible implementation, the first information is used to indicate the relationship between the time slots occupied by each of the K resources, and may include: the first information indicating the number of time slots between any two adjacent time slots in the V time slots occupied by the resources in the K resources, and the number of resources in the K resources included in each of the V time slots. V is a positive integer.

[0472] In Method 5, one of the V time slots includes one or more of the K resources. The following example illustrates Method 5.

[0473] like Figure 17As shown, assuming the K resources include resources 1 to 5, which occupy a total of 4 time slots, resource 1 is located in time slot v+5, resources 2 and 3 are located in time slot v+8, resource 4 is located in time slot v+10, and resource 5 is located in time slot v+13. Then, the relationship between the time slots of each resource in the K resources indicated by the first information can include: a 2-time slot interval between the second time slot occupied by a resource in the K resources and the first time slot occupied by a resource in the K resources; a 1-time slot interval between the third time slot occupied by a resource in the K resources and the second time slot occupied by a resource in the K resources; a 2-time slot interval between the fourth time slot occupied by a resource in the K resources and the third time slot occupied by a resource in the K resources; the second time slot occupied by a resource in the K resources includes two resources from the K resources; the first, third, and fourth time slots occupied by a resource in the K resources each include one resource from the K resources.

[0474] Optionally, the number of time slots between any two adjacent time slots in the V time slots can be equal. That is, the number of time units between the v-th time slot and the (v-1)-th time slot in the V time slots can be equal to the number of time units between the (v+1)-th time slot and the v-th time slot in the V time slots. v is a positive integer, and v is less than or equal to V.

[0475] like Figure 18 As shown, assuming the K resources include resources 1 to 3, which occupy a total of 3 time slots, with resource 1 located in time slot v, resource 2 in time slot v+5, and resource 3 in time slot v+10, then the relationship between the time slots of each resource in the K resources indicated by the first information can include: a 4-time-slot interval between the second time slot occupied by a resource in the K resources and the first time slot occupied by a resource in the K resources; a 4-time-slot interval between the third time slot occupied by a resource in the K resources and the second time slot occupied by a resource in the K resources; and each of the first, second, and third time slots occupied by the K resources includes one resource from the K resources.

[0476] It should be understood that in Method 5, the first information is used to indicate the number of time slots between any two adjacent time slots in the V time slots occupied by the K resources, which can be agreed upon through a protocol. In this case, the first information is also used to indicate the number of resources in the K resources included in each of the V time slots. It can also be understood that the first information indirectly indicates the relationship between the time slots where each of the K resources is located.

[0477] Method 6:

[0478] The first information is used to indicate the relationship between the time slots where each of the K resources is located, and may include: the first information is used to indicate the number of available time slots between every two adjacent time slots in the V time slots occupied by the resources in the K resources, and the number of resources in the K resources included in each of the V time slots.

[0479] like Figure 14 As shown, assuming the K resources include resources 1 to 5, which occupy a total of 4 time slots, resource 1 is located in time slot v, resources 2 and 3 are located in time slot v+3, resource 4 is located in time slot v+5, and resource 5 is located in time slot v+8. Then, the relationship between the time slots of each resource in the K resources indicated by the first information can include: a gap of 0 available time slots between the second time slot occupied by a resource in the K resources and the first time slot occupied by a resource in the K resources; a gap of 1 available time slot between the third time slot occupied by a resource in the K resources and the second time slot occupied by a resource in the K resources; a gap of 0 available time slots between the fourth time slot occupied by a resource in the K resources and the third time slot occupied by a resource in the K resources; the second time slot occupied by a resource in the K resources includes 2 resources from the K resources; the first, third, and fourth time slots occupied by a resource in the K resources each include 1 resource from the K resources.

[0480] It should be understood that in Method 6, the first information is used to indicate the number of available time slots between any two adjacent time slots in the V time slots occupied by the K resources, which can be agreed upon through the protocol. In this case, the first information is also used to indicate the number of resources in the K resources included in each of the V time slots. It can be understood that the first information indirectly indicates the relationship between the time slots where each of the K resources is located.

[0481] The method by which the first information indicates the relationship between the time slots of each of the K resources can be agreed upon through a protocol, such as agreeing to use method 1 or agreeing to use method 2.

[0482] When the time slot where the first resource is located refers to the position of the first resource in the target time slot set, in any of the methods 1 and 3 above, the relationship between the time slots of each of the K resources indicated by the first information may further include: the first information is also used to indicate the number of time slots included in the target time slot set, and the time slots in the target time slot set that serve as reference time slots for the first resource, such as the time slot where the first time slot in the target time slot set is located or the time slot where the last time slot in the target time slot set is located. Similarly, in any of the methods 2 and 4 above, the relationship between the time slots of each of the K resources indicated by the first information may further include: the first information is also used to indicate the number of available time slots included in the target time slot set, and the time slots in the target time slot set that serve as reference time slots for the first resource, such as the available time slot where the first time slot in the target time slot set is located or the available time slot where the last time slot in the target time slot set is located.

[0483] In this embodiment, under mode one, the offset pattern format can be understood as format one; under mode two, the offset pattern can be understood as format two; and under mode three, the offset pattern can be understood as format three. In this embodiment, the time slots containing the resources among the K resources are all available time slots, and will not be elaborated further.

[0484] In one possible implementation, the first information is used to indicate the relationship between the time slots of each of the K resources, and may include: the first information is used to indicate the relationship between the time slot of the first resource and the time slot of the second resource.

[0485] The first resource and the second resource can be from the same resource set, such as both being resources from K resource sets. Alternatively, the first resource and the second resource can be from different resource sets.

[0486] The second resource is one of the K resources, and it differs from the first resource; in other words, the second resource is one of the K resources other than the first resource. For example, if the K resources include K resources, and the first resource is the k-th resource among the K resources, then the second resource can be one of the 1st to (k-1)th resources among the K resources, or one of the (k+1)th to the k-th resources among the K resources. For instance, if the K resources include resource 1 and resource 2, and the first resource is resource 1, then the second resource is resource 2. Or, if the first resource is resource 2, then the second resource is resource 1. Similarly, if the first resource includes resources 1 to 3, and the first resource is resource 1, then the second resource can be resource 2, or the second resource can be resource 3. It should be understood that in the embodiments of this application, the first and second resources are only examples; in actual implementation, the first and second resources can also be other possible resources among the K resources.

[0487] In the case where there are two resources among the K resources, the second resource can also be understood as the resource other than the first resource among the K resources.

[0488] In one possible implementation, the first information is used to indicate the relationship between the time slots where the first resource and the second resource are located among the K resources, and may include: the time slot where the first resource is located and the time slot where the second resource is located are adjacent available time slots; or, the time slot where the first resource is located and the time slot where the second resource is located are the same available time slot; or, the available time slot where the first resource is located and the available time slot where the second resource is located are separated by G time slots.

[0489] In one possible implementation, the first information is also used to indicate the time slot where the third resource is located.

[0490] The third resource is one of the K resources, and it is different from both the first and second resources.

[0491] The time slot where the third resource is located satisfies one of the following relationships: the available time slot where the third resource is located is separated from the available time slot where the second resource is located by G time slots; or, the available time slot where the third resource is located is separated from the available time slot where the first resource is located by 2*G time slots; or, the time slot where the third resource is located is any one of the time slots where the first resource is located and the second resource is located.

[0492] In one possible implementation, the first resource, the second resource, and the third resource are all resources that trigger DCI activation. Alternatively, it can be said that the first resource, the second resource, and the third resource are all resources activated by triggering DCI.

[0493] In one possible implementation, the first information is further used to indicate the relationship between the time slots occupied by each of the K resources, including: the first information is further used to indicate the length from the first time slot to the last time slot occupied by the K resources, and the position of each of the K resources in the time slot from the first time slot to the last time slot occupied by the K resources. Alternatively, the first information is further used to indicate the number of time slots between any two adjacent time slots occupied by the K resources, and the number of first resources corresponding to each time slot in the K resources.

[0494] In one possible implementation, any two of the K resources reside in different time slots.

[0495] In one possible implementation, the number of time slots between any two adjacent time slots occupied by the resources of the K resources is the same.

[0496] In this embodiment, the first information can be carried in RRC signaling, such as RRC signaling carrying CSI configuration. A CSI configuration may include one or more CSI reporting configuration information (CSI-ReportConfigInfo) elements, and / or one or more CSI associated reporting configuration information (CSI-AssociatedReportConfigInfo) elements. When CSI resources are periodic, each CSI reporting configuration information element can be used to represent a CSI reporting configuration; when CSI resources are non-periodic, each CSI associated reporting configuration information element can be used to represent a CSI reporting configuration.

[0497] In one possible implementation where the first information carries RRC signaling for configuring the reference signal, if the CSI resource is a periodic resource, the first information can be carried within a CSI reporting configuration information element. For example, a new information element can be added within the CSI reporting configuration information element to indicate the offset pattern corresponding to that CSI reporting configuration information element.

[0498] In this way, an offset pattern associated with a CSI reporting configuration can be applied to all reference resource sets associated with that CSI reporting configuration information, thus simplifying the configuration of resource sets.

[0499] In another possible implementation, if the resources among the K resources are non-periodic resources, then the first information can be carried in the CSI associated reporting configuration information element.

[0500] For example, a new information element can be added within the channel state information associated reporting configuration information element to indicate the offset pattern corresponding to the CSI associated reporting configuration information element.

[0501] In this way, the offset pattern of a CSI-associated reporting configuration is applicable to all resource sets associated with that CSI-associated reporting configuration information element, thus simplifying the configuration of resource sets.

[0502] In another possible implementation, the first information can be carried in the information element of the Channel State Information Reference Signal Resource Set (NZP-CSI-RS-ResourceSet).

[0503] The first piece of information can be carried within an information element of the CSI-RS resource set, such as the information element of a non-zero power CSI-RS resource set (NZP-CSI-RS-ResourceSet). For example, a new information element can be added within the CSI-RS resource set information element to indicate the first piece of information. In this way, an offset pattern can be configured for each resource set, making the location of the configured resources more flexible.

[0504] It should be understood that the specific implementation of the first information in RRC signaling is only for illustrative purposes. In actual implementation, the first information can also be carried in other information elements of RRC signaling, or the first information can also be carried in one or more of RRC signaling, MAC CE signaling, or DCI signaling.

[0505] S1202, the second device transmits a first reference signal in the time slot of each of the K resources. Correspondingly, the first device receives a reference signal in the time slot of at least one of the K resources.

[0506] In this context, the time slot of each of the K resources is determined based on the time slots of at least one of the K resources and the relationship between the time slots of each of the K resources. A reference signal is used for channel state information measurement. As an example, in a scenario of aperiodic CSI reporting, for the first device, the time slot of each of the K resources is determined based on the first information and the time slot containing the trigger DCI. For instance, after receiving the trigger DCI, the first device can determine the time slot containing the trigger DCI, and based on the time slot containing the trigger DCI and the position of the first resource relative to the time slot containing the trigger DCI, determine the time slot of the first resource, such as the index of the time slot containing the first resource, and then determine the time slots of each of the K resources based on the relationship between the time slots of each of the K resources.

[0507] The following example, based on the first piece of information mentioned above, illustrates the time slot where each of the K resources is located.

[0508] In the case of method 1, combined Figure 15For example, suppose the K resources include resources 1 to 3. The first information indicates that resource 1 is located in the first time slot of the target time slot set, resource 2 is located in the first time slot of the target time slot set, and resource 3 is located in the fourth time slot of the target time slot set. The offset of the time slot where resource 1 is located relative to the triggering DCI is 2. If the triggering DCI is located in time slot v+3, then the time slot where resource 2 is located is time slot v+5, and the time slot where resource 3 is located is time slot v+9.

[0509] In the case of method 3, combined Figure 16 For example, suppose the K resources include resources 1 to 3. The first indication information indicates that the target time slot set contains 5 time slots. Resources 1 to 3 are each located in an available time slot, and each of the resources 1 to 3 is located in a different available time slot. The time slot where resource 1 is located is offset by 2 relative to the triggering DCI. If the triggering DCI is located in time slot v+3, then the time slot where resource 1 is located is time slot v+5, the time slot where resource 2 is located is time slot n+8, and the time slot where resource 3 is located is time slot n+9.

[0510] In the case of method 5, combined Figure 12 For example, suppose the K resources include resources 1 to 5. The first information indicates that the time slot where resource 2 is located is 2 time slots away from the time slot where resource 1 is located, the time slot where resource 3 is located is 0 time slots away from the time slot where resource 2 is located, the time slot where resource 4 is located is 1 time slot away from the time slot where resource 2 (or resource 3) is located, the time slot where resource 5 is located is 2 time slots away from the time slot where resource 4 is located, and the offset of the time slot where resource 1 is located relative to the trigger DCI is 2. If the time slot containing the trigger DCI is v+3, the time slot occupied by resource 2 is time slot v+5, the time slot occupied by resource 3 is time slot v+5, the time slot occupied by resource 4 is time slot v+10, and the time slot occupied by resource 5 is time slot v+13.

[0511] When the K resources include a first resource and a second resource, S1202 may include: the second device transmitting a reference signal in the time slot where the first resource and the second resource are located. Correspondingly, the first device receiving the reference signal in the time slot where at least one of the first resource and the second resource is located.

[0512] For example, the first device receives a reference signal in the time slot where at least one of the first and second resources is located. This can also be understood as the first device receiving a reference signal on the first resource, or the first device receiving a reference signal on the second resource, or the first device receiving a reference signal on both the first and second resources.

[0513] When the K resources include a first resource, a second resource, and a third resource, S1202 may include: the second device transmitting a reference signal in the time slot where the first resource, the second resource, and the third resource are located. Correspondingly, the first device receiving the reference signal in the time slot where at least one of the first to third resources is located.

[0514] In some possible implementations, the first device receives the reference signal in the time slot where at least one of the first and second resources is located. This can also be understood as the first device receiving the reference signal on the first resource and / or receiving the reference signal on the second resource.

[0515] In one possible implementation, Figure 12 The provided method may also include S1203.

[0516] S1203, the first device transmits the measurement result of the reference signal. Correspondingly, the second device receives the measurement result of the reference signal.

[0517] The measurement results of the reference signal in S1203 include the measurement results of the reference signals corresponding to at least some of the K resources.

[0518] In some possible implementations, the measurement results of the reference signal can be carried in the CSI. It should be understood that the CSI here is for illustrative purposes; in actual implementations, the measurement results of the reference signal can also be carried in other possible information or signaling.

[0519] If the first information is used to indicate the time slot of a first resource among the K resources, and the first information is also used to indicate the relationship between the time slots of each resource among the K resources, then if the resources among the K resources include CSI-RS resources, the measurement results of the reference signal may include the results of interference measurements. If the resources among the K resources include CSI-IM resources, then the measurement results of the reference signal may include the results of interference measurements. If the resources among the K resources include channel measurement resources, then the measurement results of the reference signal may include the results of channel measurements.

[0520] Combination Figure 12 The provided auxiliary channel measurement method allows the second device to indicate the relationship between the time slots of each of the K resources to the first device, and to transmit a reference signal in the time slot of each resource. The first device can then receive the reference signal corresponding to each resource in the time slot of each resource among the multiple resources based on the first information. Thus, when there are multiple time slots for the K resources, the first device can receive reference signals in multiple time slots, thereby assisting in the measurement of channel state information for multiple beams. Furthermore, this auxiliary channel measurement method can be applied to many more scenarios.

[0521] In one possible implementation, Figures 8-18 The provided method may also include: the first device transmitting the measurement result of a reference signal.
