Technical Field

[0002] The present application relates to the field of communications, and more specifically, to a method and apparatus for transmitting channel state information. Background Art

[0003] With the gradual evolution of communication systems, "low carbon" has received more and more attention in communication networks, especially how to reduce the energy consumption of network equipment (for example, base stations). At present, the purpose of saving transmission power can be achieved by dynamically shutting down some transmitting antennas. In the case of dynamic antenna shutdown, the terminal device can measure the channel state information (CSI) for different antenna shutdown conditions and report the CSI measurement results to the network device so that the network device can perform data scheduling. The terminal device includes multiple CSIs in a CSI report for reporting. If the CSI report is discarded and updated in accordance with the existing standard, it will cause the terminal device to fail to work properly or waste performance. Therefore, how to report, update and discard the CSI report is an urgent problem to be solved.

[0223] The technical solution in this application will be described below with reference to the accompanying drawings.

[0225] The terminal device in the embodiments of the present application may refer to user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network or a terminal device in an evolved public land mobile network (PLMN), etc., and the embodiments of the present application are not limited to this. For example, the terminal device can be an on-board device, a complete vehicle device, an on-board module, a vehicle, an on-board unit (OBU), a roadside unit (RSU), a telematics box (T-box), a chip or a system on chip (SOC), etc. The above chip or SOC can be installed in a vehicle, OBU, RSU or T-box.

[0226] The terminal devices involved in the embodiments of the present application also include at least one of user equipment, augmented reality AR / virtual reality VR / extended reality XR devices, wearable devices, smart home appliance terminals, terminal devices and communication modules of terminal devices, mobile phones and communication modules in mobile phones, vehicles and communication modules in vehicles, information processing equipment, display devices, network devices, base stations, TRPs, customer premise equipment (CPE), routers, network access devices, etc. Considering Uu (UTRAN-to-terminal equipment) air interface transmission, the two parties of wireless communication include network devices and user communication equipment; considering SL air interface transmission, the transceiver ends of wireless communication are both user communication equipment. The network device can be a traditional macro base station eNB in ​​a traditional UMTS / LTE wireless communication system, a micro base station eNB in ​​a heterogeneous network (HetNet) scenario, a baseband processing unit (BBU) and a remote radio unit (RRU) in a distributed base station scenario, a baseband pool BBU pool and a radio frequency unit RRU in a CRAN scenario, and a gNB in ​​a wireless communication system.

[0227] In the embodiment of the present application, the network device can be any device with wireless transceiver function. The device includes but is not limited to: an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved NodeB, or a home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It can also be a gNB in ​​a 5G, such as NR, system, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc.

[0228] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC), medium access control (MAC), and physical (PHY) layers. The AAU implements some physical layer processing functions, RF processing, and active antenna-related functions. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or by both the DU and the AAU. It is understood that a network device can be a device that includes one or more of a CU node, a DU node, or an AAU node. In addition, the CU may be classified as a network device in an access network (radio access network, RAN), or may be classified as a network device in a core network (core network, CN), which is not limited in this application.

[0229] Network equipment provides services for cells, and terminal devices communicate with cells through transmission resources allocated by the network equipment (for example, frequency domain resources, or spectrum resources). The cell can belong to a macro base station (for example, a macro eNB or macro gNB), or to a base station corresponding to a small cell. Small cells here can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0230] FIG1 is a schematic diagram of a possible, non-limiting system suitable for embodiments of the present application.

[0231] As shown in Figure 1 , the communications system includes a radio access network (RAN) 100. RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 1 , collectively referred to as 110) and at least one terminal device (e.g., 120a-120j in Figure 1 , collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1 ). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wiredly connected to core network 200. The core network devices in core network 200 and RAN node 110 in RAN 100 may be separate physical devices, or they may be the same physical device that integrates core network logical functions and radio access network logical functions.

[0232] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0233] RAN node 110, sometimes also referred to as access network equipment, network equipment, RAN entity, or access node, constitutes part of a communication system and facilitates wireless access for terminals. Multiple RAN nodes 110 in a communication system can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminal 120j accessing RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0234] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (such as 110a in FIG1 ), a micro base station or an indoor station (such as 110b in FIG1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, a RAN node may also be a server, a wearable device, a vehicle or an onboard device. For example, an access network device in vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in this application may also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The RAN node in this application may also be a logical node, a logical module or software that can implement all or part of the RAN node functions.

[0235] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0236] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and 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.

[0237] The RAN node can also be expressed in different ways. Unless otherwise specified in this application, the network device is used to express it.

[0238] It should be understood that Figure 1 is merely a schematic diagram and may include other devices not shown. In addition, the embodiments of the present application do not limit the number of terminal devices and network devices included in the communication system.

[0239] In an embodiment of the present application, a terminal device or a network device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. In addition, the present application does not specifically limit the specific structure of the execution subject of the method provided by the present application. As long as it is possible to communicate according to the method provided by the embodiment of the present application by running a program that records the code of the method provided by the present application, for example, the execution subject of the method provided by the embodiment of the present application can be a terminal device or a network device, or a functional module in a terminal device or a network device that can call a program and execute the program.

[0240] In addition, various aspects or features of the present application can be implemented as methods, apparatuses, or articles of manufacture using standard programming and / or engineering techniques. The term "article of manufacture" as used in this application covers computer programs that can be accessed from any computer-readable device, carrier, or medium.

The term "machine-readable medium" may include, but is not limited to, wireless channels and various other media capable of storing, containing, and / or carrying instructions and / or data.

[0241] In this application, "sending information to...(terminal)" can be understood as the destination of the information being the terminal. This can include sending information to the terminal directly or indirectly. "Receiving information from...(terminal)" can be understood as the source of the information being the terminal, which can include receiving information from the terminal directly or indirectly. The information may undergo necessary processing between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0244] 1. Transmitter (TX)

[0245] The radio frequency (RF) transmission channel is referred to as the transmission channel. One transmission channel corresponds to one physical antenna port. The transmission channel can receive the baseband signal from the baseband chip, perform RF processing (such as up-conversion, amplification and filtering) on ​​the baseband signal to obtain a radio frequency signal, and finally radiate the radio frequency signal into space through the antenna. Specifically, the transmission channel may include one or more electronic devices such as an antenna switch, an antenna tuner, a power amplifier (PA), a mixer, a local oscillator (LO), and a filter. These electronic devices can be integrated into one or more chips as needed. The antenna can sometimes also be considered as part of the transmission channel. In the embodiments of the present application, turning off the antenna can also be referred to as turning off the transmission channel.

[0247] Antenna ports can also be referred to as ports. Unless otherwise specified, antenna ports in the embodiments of this application refer to logical antenna ports, not physical antenna ports. An antenna port can be associated with one or more transmit channels. The signal on each antenna port is transmitted through the one or more transmit channels associated with it. When an antenna port is associated with multiple transmit channels, the signal on the antenna port is weighted by a weighting coefficient and then transmitted through the multiple transmit channels associated with it. It can also be understood that multiple physical antennas are weighted by the weighting coefficient to form a logical antenna. The weighting coefficient here can be a complex number or a real number, and the weighting coefficients for different physical antennas may be the same or different. Each antenna port has corresponding time-frequency resources and reference signals. The time-frequency resources corresponding to different antenna ports may be the same or different. The reference signal transmitted by the base station through antenna port A can be used by the terminal to estimate the characteristics of the radio channel from antenna port A to the terminal. The characteristics of the radio channel can be used by the terminal to estimate the physical channel transmitted through antenna port A, or to determine information such as the modulation order and code rate during data transmission. A reference signal can correspond to one or more antenna ports, and it can also be understood that a reference signal can be transmitted through one or more antenna ports.

[0248] Antenna shutdown can be divided into two types: the first type, antenna shutdown affects the (logical) antenna port. When the antenna is shut down, the number of antenna ports for CSI-RS will change; the second type, antenna shutdown does not affect the (logical) antenna port. That is, when the antenna is shut down, the antenna port for CSI-RS does not change.

[0249] 3. Channel State Information (CSI)

[0250] In the process of a wireless signal traveling from the transmitter to the receiver through a wireless channel, it may experience scattering, reflection, and energy attenuation with distance, resulting in fading. In addition, the wireless signal may also be interfered with by other signals at the receiver, thereby affecting the reception of the wireless signal. Characteristics such as signal attenuation and interference can be characterized by channel state information (CSI). Specifically, CSI may include at least one of a channel quality indication (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), a reference signal received power (RSRP), and a signal to interference plus noise ratio (SINR). These CSIs may be sent by the terminal device to the network device via a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH). In the embodiments of the present application, if there is no logical conflict, the terms "CQI" and "CQI index" may be interchangeable, and the terms "reporting," "feedback," and "sending" may be interchangeable.

[0251] 4. Reference signal

[0252] A reference signal is a known signal provided by a transmitter to a receiver for channel estimation or channel detection. In the embodiments of the present application, the reference signal can be used for channel measurement, interference measurement, etc., such as measuring CSI-related parameters.

[0253] 5. Reference signal resources

[0254] The reference signal resource may specifically include at least one of a reference signal time-frequency resource, an antenna port, a power resource, and a scrambling code. A network device may send a reference signal based on the reference signal resource, and a terminal device may receive a reference signal based on the reference signal resource. In the embodiments of the present application, the one or more antenna ports corresponding to the reference signal resource may also be understood as the one or more antenna ports included in the reference signal resource.

[0255] Specifically, the reference signal involved in the embodiments of the present application may be a channel state information reference signal (CSI-RS) or an SSB. Correspondingly, the reference signal resource may be a CSI-RS resource or an SSB resource.

[0256] 6. Discontinuous reception (DRX)

[0257] When a connected terminal device is in DRX mode, it no longer continuously monitors the physical downlink control channel (PDCCH), thereby saving energy and extending standby time. After the DRX mode is activated, the terminal device will exist in two states: active and dormant. When the terminal device is in a dormant state, the terminal device will not monitor certain types of PDCCH. For example, as specified in the existing NR standard, a terminal device in a dormant period (i.e., not in an active time) will not detect PDCCH scrambled by C-RNTI, CI-RNTI, CS-RNTI, INT-RNTI, SFI-RNTI, SP-CSI-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, TPC-SRS-RNTI, AI-RNTI, SL-RNTI, SLCS-RNTI. Furthermore, the terminal device will not receive or send such PDCCH-scheduled or activated signals. For example, PDCCH scrambled by C-RNTI can be used to schedule PDSCH or PUSCH. The terminal device does not detect the PDCCH, that is, the terminal device will not receive and send PDSCH or PUSCH. During the active period, the terminal device's behavior of detecting PDCCH is not restricted.

[0258] 7. Multiple CSI reporting

[0259] The network device can configure at least one CSI reporting configuration for the terminal device through high-layer signaling. Each CSI reporting configuration includes a CSI reporting configuration identification number (CSI report configuration ID). Currently, there are three types of CSI reporting methods supported in the new radio access technology NR: periodic CSI (P-CSI) reporting, semi-persistent CSI (SP-CSI) reporting, and aperiodic CSI (A-CSI) reporting.

[0260] Currently, a CSI report configuration can include L sub-configurations. For periodic CSI reporting, the network device reports CSI of L sub-configurations. For semi-continuous CSI reporting and non-periodic CSI reporting, the network device can trigger the terminal device to send N CSI in one CSI report. N CSIs correspond to N sub-configurations, and N sub-configurations are included in L sub-configurations.

[0261] When the first type of antenna shutdown is adopted, the sub-configuration includes: port subset indication and codebook configuration. When the second type of antenna shutdown is adopted, as shown in Figure 2, the sub-configuration includes a resource set, which includes the index of one or more CSI-RS resources.

[0262] 8. CSI Reference Resources

[0263] The terminal device can determine the CSI reference resource. In the time domain, the CSI reference resource is defined as the downlink time slot nn CSI_ref , time slot n is the time slot in which the terminal device reports the CSI report. The CSI reference resource is related to the CSI report. That is, each CSI reporting moment corresponds to a CSI reference resource. For example, for periodic CSI or semi-continuous CSI reporting, CSI is reported periodically. For each reporting moment, there is a corresponding CSI reference resource. The network device can configure periodic measurement resources for the terminal device. Which measurement resource the terminal device uses for measurement is determined by the CSI reference resource. The measurement resource corresponding to the CSI report must be located before the CSI reference resource.

[0264] In one possible implementation, as shown in FIG3 , after the CSI report configuration is reconfigured, or the serving cell is activated, or the BWP is switched or the semi-persistent CSI is activated, if at least one CSI-RS resource for channel measurement and the CSI-RS resource for interference measurement in the time domain is not later than the CSI reference resource, the terminal device reports the CSI report; if all CSI-RS resources for channel measurement and the CSI-RS resources for interference measurement in the time domain are later than the CSI reference resource, the terminal device discards the CSI report.

[0265] It should be understood that, as shown in Figure 4, sub-configuration 1 includes CSI-RS resource 1, and sub-configuration 2 includes CSI-RS resource 2. After the CSI report configuration is reconfigured, or the serving cell is activated, or the BWP is switched or the semi-continuous CSI is activated, since the CSI-RS resource 1 included in sub-configuration 1 is earlier than the CSI reference resource, and the CSI-RS resource 2 included in sub-configuration 2 is later than the CSI reference resource, the CSI of sub-configuration 1 can be reported, and the CSI of sub-configuration 2 cannot be reported. However, if the reporting and / or discarding is performed in units of CSI reports in the above implementation method, then the CSI of sub-configuration 1 and sub-configuration 2 need to be reported, but the actual terminal device cannot complete the CSI reporting of sub-configuration 2, resulting in the terminal device being unable to work normally.

[0266] It should be noted that FIG3 and FIG4 only show schematic diagrams of CSI-RS resources used for channel measurement, but do not show CSI-RS resources used for interference measurement. The specific position relationship should be based on the above description.

[0267] 9. CSI calculation time

[0268] If downlink control information (DCI) triggers N CSI reports on a PUSCH, the terminal device will provide a valid CSI for the nth triggered CSI report, which needs to meet the following conditions:

[0269] Uplink symbols used to carry CSI reports, no earlier than Z ref Symbol; and, used to carry the uplink symbol of the nth CSI report, no earlier than Z' ref(n) symbol.

[0270] Among them, Z ref Defined as T after the last symbol of the PDCCH used to trigger the CSI report proc,CSI The next up symbol after the time length, T proc,CSI =(Z)(2048+144)·κ2 -μ ·T c . Z' ref(n) Defined as T′ after the last symbol of the CSI resource proc,CSI Next uplink symbol after time length, T′ proc,CSI =(Z′)(2048+144)·κ2 -μ ·T c When the aperiodic CSI-RS is used for channel measurement of the nth triggered CSI report, the CSI resource is the latest one among the CSI-RS for channel measurement, the CSI-IM for interference measurement, and the aperiodic CSI-RS for interference measurement. proc,CSI is the CSI calculation time corresponding to N CSI reports, T′ proc,CSI CSI calculation time for the nth CSI report.

[0271] In one possible implementation, as shown in FIG5 , when DCI triggers N CSI reports, if the first uplink symbol carrying the nth CSI report is earlier than symbol Z′ ref(n) If the number of triggered reports is 1 (ie, N=1) and no HARQ-ACK or transport block is multiplexed on the PUSCH, the terminal device ignores the DCI; otherwise, the terminal device does not update the CSI that triggers the nth CSI report.

[0272] It should be understood that, as shown in FIG6 , sub-configuration 1 includes CSI-RS resource 1, and sub-configuration 2 includes CSI-RS resource 2. CSI-RS resource 1 and CSI-RS resource 2 are used for channel measurement. CSI-RS resource 1 is the last resource in the time domain among the reference signal resources for interference measurement and the reference signal resources for channel measurement corresponding to sub-configuration 1. CSI-RS resource 2 is the last resource in the time domain among the reference signal resources for interference measurement and the reference signal resources for channel measurement corresponding to sub-configuration 2. If, according to the above implementation, sub-configuration 1 and sub-configuration 2 correspond to the same Z2′ ref(n) , then the reporting resource PUSCH is earlier than this time point, and the terminal device will not update these two CSIs, but in fact the Z1' corresponding to sub-configuration 1 ref(n) It should be earlier, reporting resource PUSCH later than Z' of sub-configuration 1 ref(n) Therefore, the CSI of sub-configuration 1 can be updated. Therefore, the above implementation may cause some CSI that meets the conditions to be unable to be updated, affecting the performance of CSI reporting.

[0273] 10. CSI processing unit (CPU)

[0274] The terminal needs to occupy a certain amount of computing or storage resources to perform CSI measurement. The 3GPP protocol uses the number of CPUs to represent the resources required for the terminal device to process CSI. The terminal device will report to the network device the number of CPUs that the terminal device can support, that is, the maximum number of CPUs N. CPU . For example, terminal device 1 will inform the network device that the maximum number of CPUs it supports is 10; terminal device 2 will inform the network device that the maximum number of CPUs it supports is 15. The maximum number of CPUs supported refers to the number of CPUs supported simultaneously, which can be the number of CPUs supported simultaneously by one carrier, or the number of CPUs supported simultaneously by all carriers. For example, the terminal device only supports one CPU, which only means that at the same time, the terminal device will only have one CPU used for CSI processing.

[0275] In one possible implementation, if CSI reporting occupies L CPUs in one OFDM symbol, then N CPU - L CPUs are not occupied. If the terminal device starts calculating N CSI reports on this OFDM symbol, and the sum of the number of CPUs occupied by the calculation of N CSI reports and the number of L CPUs is greater than N CPU , then the terminal device does not need to update the CSI of the NM lowest priority CSI reports, where M is the number that satisfies the formula The maximum integer.

[0276] It should be understood that in the above implementation, when the number of CPUs exceeds the capabilities of the terminal device, the terminal device will not update the CSI report. However, the CPU of the actual terminal device can support the update of part of the CSI in the CSI report, thereby failing to fully utilize the capabilities of the terminal device and causing the performance of the terminal device to be wasted.

[0277] 11. CSI reporting priority

[0278] When the uplink resources occupied by two CSI reports overlap in at least one OFDM symbol and are transmitted on the same carrier, the two CSI reports are said to conflict. When the terminal device is configured to send two conflicting CSI reports, the CSI of the two CSI reports can be multiplexed to another reporting resource (i.e., an uplink resource that is not overlapping in the time domain as described above) for reporting. If the number of bits that can be carried by the reporting resource is less than the total number of CSI bits of the two CSI reports, the terminal device will discard the two CSI reports in order of priority from low to high.

[0279] The priority of the CSI report can be calculated by the following formula: iCSI =2·N cells ·M s y+N cells ·M s k+M s ·c+s.

[0280] The value of y is determined by the type of CSI report. For periodic CSI reports carried by PUSCH, y = 0; for semi-persistent CSI reports carried by PUSCH, y = 1; for semi-persistent CSI reports carried by PUCCH, y = 2; for periodic CSI reports carried by PUCCH, y = 3. The value of k is related to the content of the CSI report. If the CSI report contains L1-RSRP or L1-SINR, k = 0; if the CSI report does not contain L1-RSRP or L1-SINR, k = 1. c is the index value of the serving cell, N cells It is a high-level parameter, the maximum number of serving cells maxNrofservingCells; s is the configuration identifier of the CSI report, M s It is a high-level parameter. The maximum number of CSI report configurations is maxNrofCSI-ReportConfigurations.

[0281] If the first report is associated with iCSI If the value is lower than the second report, the priority of the first CSI report is considered to be lower than the priority of the second CSI report.

[0282] The CSI report can be divided into two parts: Part 1 and Part 2. Part 1 includes: rank indicator (RI), resource indicator (CSI-RS resource indicator, CRI), and CQI of the first codebook. Part 2 includes wideband CQI of the second codebook when RI is greater than 4, wideband LI, wideband PMI, and subband CSI. Part 1 has a higher priority than Part 2. The priority of Part 1 is subject to the priority of the CSI report; the priority of CSI part 2 is as follows: the highest priority is the wideband part 2 CSI of 2 CSI reports, followed by the subband CSI of odd subbands of higher priority CSI reports, the subband CSI of even subbands of higher priority CSI reports, the subband CSI of odd subbands of lower priority CSI reports, the subband CSI of even subbands of lower priority CSI reports, and so on.

[0283] In a possible implementation, when a CSI report has a time domain conflict, the two CSI reports are discarded based on the priorities of the two CSI reports and the different parts of the CSI reports.

[0284] It should be understood that when a CSI report domain conflict occurs, if a CSI report configuration includes multiple sub-configurations, according to the above-mentioned discarding rules, multiple CSIs corresponding to multiple sub-configurations will be uniformly discarded, resulting in insufficient utilization of reporting resources. At the same time, the discarding prevents the network device from obtaining more CSI information, affecting performance.

[0285] Based on the above implementation method, the discarding and / or updating of CSI reports is performed on a CSI report basis, and the problem that arises when a CSI report includes multiple CSIs. The present application provides a CSI transmission method that discards or updates CSI reports on a sub-configuration basis through the relevant rules of the reference resources, calculation time, or CSI processing unit corresponding to each sub-configuration, thereby ensuring normal CSI reporting of the terminal device and fully utilizing the CSI reporting resources and computing power.

[0286] It is understood that the schematic diagrams of the methods in this application use network devices and terminal devices as examples of the execution entities of the interactive diagrams to illustrate the methods, but this application does not limit the execution entities of the interactive diagrams. For example, the network device in the figure can also be a module applied to the network device (such as a chip, a chip system, or a processor), or a logical node, a logical module, or software that can implement all or part of the functions of the network device; the terminal device in the figure can also be a module applied to the terminal device (such as a chip, a chip system, or a processor), or a logical node, a logical module, or software that can implement all or part of the functions of the terminal device.

[0287] In the illustrations provided in this application, the dotted box indicates that the step is a step that may be implemented in the method, and may also be an optional step implemented in other steps, which will not be repeated below.

[0288] FIG7 is a schematic diagram of a CSI transmission method 200 provided in an embodiment of the present application. As shown in FIG7 , the method 200 includes at least the following steps:

[0289] S210, the network device sends first configuration information, and correspondingly, the terminal device receives the first configuration information.

[0290] The first configuration information may be a CSI report configuration.

[0291] The first CSI report configuration indicates L sub-configurations, each of the L sub-configurations indicates at least one CSI-RS resource in a reference signal resource set, and the CSI-RS resources indicated by the L sub-configurations are included in a reference resource set, and the reference signal resources are used for channel measurement. Each of the L sub-configurations indicates at least one CSI-RS resource in a reference signal resource set, and the at least one CSI-RS resource may be part of the CSI-RS resources in the reference signal resource set. Exemplarily, the reference signal resource set includes CSI-RS resource 1 and CSI-RS resource 2. There are L=2 sub-configurations, numbered sub-configuration 1 and sub-configuration 2, sub-configuration 1 indicates CSI-RS resource 1, and sub-configuration 2 indicates CSI-RS resource 2.

[0292] Each of the L sub-configurations further indicates at least one second reference signal resource in a second reference signal resource set, which is used for interference measurement. This indication may be direct or indirect. The indirect indication may be: the sub-configuration indicates at least one CSI-RS resource used for channel measurement, and each of the at least one CSI-RS resource is associated with a reference signal resource used for interference measurement. The association method may be predefined, for example, both resources are associated one-to-one in index order.

[0293] The first configuration information may also include a public configuration, and the public configuration includes at least one of the configuration information of the CQI table, the configuration information of the CSI reporting amount, and the codebook configuration information. The public configuration may be a public configuration corresponding to L sub-configurations, which may be understood as follows: in the following step S240, the N first CSIs are determined according to the N first sub-configurations, that is, the N first CSIs are determined according to the N first sub-configurations and part of the information included in the public configuration corresponding to the N sub-configurations, and each first CSI is determined according to a first sub-configuration and the public configuration. The public configuration corresponding to the L sub-configurations may also include other configuration information, and the other configuration information may be used to determine the N first CSIs or may not be used to determine the N first CSIs. For example, other configuration information may be used to transmit the N first CSIs, and this application does not limit this.

[0294] For example, as shown in FIG2 , a sub-configuration may include an index of a CSI-RS resource, that is, indicating a CSI-RS resource by index. Sub-configuration #1 includes the indexes of CSI-RS resource 1 and CSI-RS resource 2, and sub-configuration 2 includes the indexes of CSI-RS resource 3 and CSI-RS resource 4. CSI-RS resources used for channel measurement and interference measurement resources used for interference measurement are sequentially associated in descending order of reference signal indexes.

[0295] It should be noted that, in the embodiment of the present application, the order of the reference signal resources in the reference signal resource set can be understood as the order in which the identifiers / indexes of the reference signal resources appear in the configuration information of the reference signal resource set.

[0296] S220: Determine first time domain resources corresponding to the M sub-configurations according to the first configuration information.

[0297] M sub-configurations belong to L sub-configurations, where M is a positive integer less than or equal to L.

[0298] It should be understood that when the CSI report configuration is a periodic CSI report configuration, the M sub-configurations are L sub-configurations (a periodic CSI report configuration with L sub-configurations means reporting L sub-configurations); when the CSI report configuration is a semi-continuous CSI report configuration or a non-periodic CSI report configuration, the M sub-configuration is the sub-configuration triggered by the network device among the L sub-configurations.

[0299] In one possible implementation, there may be M first time domain resources corresponding to the M subconfigurations, with the M first time domain resources corresponding one-to-one to the M subconfigurations. The first time domain resource may be a CSI reference resource. The CSI reference resource corresponding to any one of the M subconfigurations may be used to calculate the CQI for that subconfiguration. Optionally, the position of the first time domain resource in the time domain is determined based on the reference signal resource indicated by the subconfiguration corresponding to the first time domain resource.

[0300] For example, when the CSI reporting configuration is periodic CSI reporting or semi-persistent CSI reporting, the CSI reference resource of the uplink time slot n' for CSI reporting is defined as the downlink time slot where K iffset For high-level parameter configuration, is the subcarrier spacing, n is determined based on n', It is determined based on the number of CSI-RS resources included in the sub-configuration. When the number of CSI-RS resources included in the sub-configuration is 1, Greater than or equal to When the number of CSI-RS resources included in the sub-configuration is greater than 1, Greater than or equal to

[0301] In another possible implementation, the first time domain resource corresponding to the M subconfigurations may be one. The first time domain resource may be a CSI reference resource. The CSI reference resource corresponding to the M subconfigurations may be used to calculate the CQI for each of the M subconfigurations. Optionally, the time domain position of this one first time domain resource is determined based on the reference signal resources indicated by the M or L subconfigurations.

[0302] For example, let the time slot where the CSI is reported be slot n', then the time domain position of the CSI reference resource is n is the reporting time slot corresponding to the reporting time n'. The calculation formula is as follows: Among them, μ UL and μ DL For periodic CSI reporting and semi-persistent CSI reporting, if M or L sub-configurations configure a total of 1 CSI-RS / SSB resource for channel measurement, then is greater than or equal to If M or L sub-configurations are configured with multiple CSI-RS / SSB resources for channel measurement, is greater than or equal to The minimum value of .

[0303] S240, the terminal device sends a first CSI report, and accordingly, the network device receives the first CSI report.

[0304] The terminal device may send a first CSI report on a first CSI reporting resource. The configuration information of the first reporting resource may be included in the first configuration information, or may be indicated by other indication information. Specifically, in the case where the first reporting resource is a physical uplink control channel PUCCH, the configuration information of the first reporting resource is PUCCH resource configuration information, and the PUCCH resource configuration information is included in the first configuration information. Specifically, in the case where the first reporting resource is a physical uplink shared channel PUSCH, the configuration information of the first reporting resource is carried in the downlink control information DCI, and the configuration information of the first reporting resource may include time domain resource configuration information of PUSCH and frequency domain resource configuration information of PUSCH. The time domain resource control information of PUSCH may be included in the time domain resource allocation domain (TDRA) of DCI, and the frequency domain resource control information of PUSCH may be included in the frequency domain resource allocation domain (FDRA) of DCI. The DCI may be the DCI used to trigger the first CSI report.

[0305] The first CSI report includes N first CSIs, the N first CSIs are determined according to N first subconfigurations, the N first CSIs are determined according to the N first subconfigurations, the at least one reference signal resource indicated by the first subconfiguration includes a first reference signal resource, the first reference signal resource is no later than the first time domain resource corresponding to the first subconfiguration in the time domain, and N is a positive integer less than or equal to M. The first reference signal resource is no later than the first time domain resource corresponding to the first subconfiguration in the time domain, which can be replaced by the first reference signal resource and at least one reference signal resource used for interference measurement being no later than the first time domain resource corresponding to the first subconfiguration in the time domain, and the reference signal resource used for interference measurement is indicated by the first subconfiguration.

[0306] It should be understood that in the present application, CSI corresponds to sub-configuration or sub-configuration corresponds to CSI, which can be understood as CSI being obtained by measuring the CSI-RS resources indicated by the sub-configuration.

[0307] The first CSI report does not include MN second CSIs, N CSIs correspond to N first sub-configurations, N first sub-configurations are included in M ​​sub-configurations, and MN second CSIs correspond to MN second sub-configurations (i.e., sub-configurations in the M sub-configurations except the N first sub-configurations). In other words, the terminal device will discard the MN second CSIs, the MN second CSIs correspond to the MN second sub-configurations, and the reference signal resources indicated by the second sub-configuration are later than the first time domain resources corresponding to the second sub-configuration in the time domain; in other words, the reference signal resources indicated by the second sub-configuration and the reference signal resources used for interference measurement are later than the first time domain resources corresponding to the first sub-configuration in the time domain.

[0308] The first time domain resource may be a time domain resource of a CSI reference resource. After the CSI report configuration is reconfigured, or the serving cell is activated, or the BWP is switched, or the semi-persistent CSI is activated, if the time domain resource of at least one CSI-RS resource (i.e., the first reference signal resource) in the CSI-RS resources included in the first sub-configuration is no later than the first time domain resource corresponding to the first sub-configuration, then the CSI corresponding to the first sub-configuration is included in the CSI report; otherwise, the CSI corresponding to the first sub-configuration is not included in the first CSI report.

[0309] For example, as shown in FIG8 , subconfiguration 1 indicates CSI-RS resource #1, and subconfiguration 2 indicates CSI-RS resource #2. CSI-RS resource #1 and CSI-RS resource #2 are used for channel measurement. CSI-RS resource #1 is one of the reference signal resource for interference measurement and the reference signal resource for channel measurement corresponding to subconfiguration #1, and CSI-RS resource 2 is one of the reference signal resource for interference measurement and the reference signal resource for channel measurement corresponding to subconfiguration 2. The terminal device determines the first time domain resource 1 corresponding to subconfiguration 1 and the first time domain resource 2 corresponding to subconfiguration 2. The resources indicated by subconfiguration 1 include CSI-RS resource #1 (i.e., the first reference signal resource) that is earlier in the time domain than the first time domain resource 1 corresponding to subconfiguration 1. Therefore, subconfiguration 1 belongs to one of the N first subconfigurations, and its corresponding CSI is included in the reported CSI report. Accordingly, the resources indicated by subconfiguration 2 do not include a reference signal resource that is earlier than the first time domain resource 2 corresponding to subconfiguration 2. Therefore, subconfiguration 2 does not belong to the N first subconfigurations.

[0310] As another example, as shown in FIG8 , subconfiguration 1 indicates CSI-RS resource #1, and subconfiguration 2 indicates CSI-RS resource #2. CSI-RS resource #1 and CSI-RS resource #2 are used for channel measurement. CSI-RS resource #1 is one of the reference signal resource for interference measurement and the reference signal resource for channel measurement corresponding to subconfiguration #1, and CSI-RS resource 2 is one of the reference signal resource for interference measurement and the reference signal resource for channel measurement corresponding to subconfiguration 2. The terminal device determines a first time domain resource corresponding to subconfiguration 1 and subconfiguration 2 (which can be either first time domain resource 1 or first time domain resource 2, with first time domain resource 1 being used as an example here). The resources indicated by subconfiguration 1 include CSI-RS resource #1 (i.e., a first reference signal resource) that is earlier in the time domain than the first time domain resource 1 corresponding to subconfiguration 1. Therefore, subconfiguration 1 belongs to one of the N first subconfigurations, and its corresponding CSI is included in the reported CSI report. Correspondingly, the resources indicated by sub-configuration 2 do not include a reference signal resource earlier than the first time domain resource 1 corresponding to sub-configuration 2, and therefore sub-configuration 1 does not belong to the N first sub-configurations.

[0311] In one possible implementation, the M CSIs may include a reference CSI, the reference CSI corresponds to a reference sub-configuration, the reference CSI may be one of the N first CSIs, and the MN second CSIs do not include the reference CSI. The reference CSI includes first information, the first information includes at least one of CRI, PMI, and RI, and the other CSIs in the N first CSIs except the reference CSI may not include the first information. Further, the terminal device determines the reference CSI in the M CSIs, the reference CSI is the CSI corresponding to the reference sub-configuration, and the reference sub-configuration is the first sub-configuration in the N first sub-configurations that meets at least one of the following conditions: the reference sub-configuration is the sub-configuration with the highest corresponding priority among the N first sub-configurations; or, the reference sub-configuration is the first sub-configuration with the lowest sub-configuration index among the N first sub-configurations; the reference sub-configuration is the sub-configuration with the largest number of ports of the CSI-RS resource among the N first sub-configurations. The reference sub-configuration is not included in the MN second sub-configurations. When the terminal device reports N first CSIs, it may report the N first CSIs in a compressed manner. For example, one uncompressed CSI and multiple compressed CSIs are reported, the uncompressed CSI includes the first information, and the compressed CSI does not include the first information. When the network device instructs the terminal device to report M CSIs, the terminal device needs to determine which CSI is not to be compressed. Since the terminal device will determine that MN second CSIs among the M CSIs will not be reported based on the relationship between the reference signal resources corresponding to the sub-configuration and the CSI reference resources, the terminal device needs to determine one of the first CSIs as the reference CSI based on the N first CSIs actually reported. The method for the terminal device to determine the reference CSI can refer to the aforementioned method.

[0312] In one possible implementation, the first reference signal resource is further located within a first time period, where the first time period is a time period during which discontinuous reception (DRX) of the terminal device is activated. The first CSI report includes N first CSIs, where the N first CSIs are determined based on N first sub-configurations, where the at least one reference signal resource indicated by the first sub-configuration includes a first reference signal resource, where the first reference signal resource is no later than the first time domain resource corresponding to the first sub-configuration in the time domain and is located within a first time period, where the DRX of the terminal device is activated.

[0313] Exemplarily, as shown in FIG9 , subconfiguration 1 indicates CSI-RS resource #1, and subconfiguration 2 indicates CSI-RS resource #2. CSI-RS resource #1 and CSI-RS resource #2 are used for channel measurement. CSI-RS resource #1 is one of the reference signal resource for interference measurement and the reference signal resource for channel measurement corresponding to subconfiguration #1, and CSI-RS resource 2 is one of the reference signal resource for interference measurement and the reference signal resource for channel measurement corresponding to subconfiguration 2. The terminal device determines the first time domain resource 1 corresponding to subconfiguration 1 and the first time domain resource 2 corresponding to subconfiguration 2. If DRX is configured for the terminal device, the resources indicated by subconfiguration 1 include CSI-RS resource #1 (i.e., the first reference signal resource) that is earlier in the time domain than the first time domain resource 1 corresponding to subconfiguration 1 and is included in the DRX activation time (i.e., the first time period). Therefore, subconfiguration 1 belongs to one of the N first subconfigurations, and its corresponding CSI is included in the reported CSI report.

[0314] In another possible implementation, when the reference signal resources indicated by any of the M sub-configurations include at least one reference signal resource that is no later than the first time domain resource corresponding to any of the sub-configurations in the time domain, the CSI corresponding to all M sub-configurations is transmitted; when the M sub-configurations include the first sub-configuration, and the reference signal resources indicated by the first sub-configuration are all later than the first time domain resource corresponding to the first sub-configuration in the time domain, the CSI corresponding to the M sub-configurations is discarded. In other words, when all M CSIs meet the conditions, all M CSIs are retained; and if one of the M CSIs does not meet the conditions, all M CSIs are discarded.

[0315] In another possible implementation, when the reference signal resources indicated by any sub-configuration in the M sub-configurations include at least one reference signal resource that is no later than the first time domain resource corresponding to the any sub-configuration in the time domain, and the at least one reference signal resource is located within a first time period, the CSI corresponding to all M sub-configurations is sent, and the first time period is the DRX activation time period of the terminal device; when the M sub-configurations include the first sub-configuration, and the reference signal resources indicated by the first sub-configuration are all later than the first time domain resource corresponding to the first sub-configuration in the time domain and / or are not located within the first time period, the CSI corresponding to the M sub-configurations is discarded. In other words, when all M CSIs meet the conditions, all M CSIs are retained; if one of the M CSIs does not meet the conditions, all M CSIs are discarded.

[0316] Optionally, the terminal device may execute S230 to determine N first sub-configurations from the M sub-configurations according to positions of the first time domain resources and the reference signal resources indicated by the M sub-configurations in the time domain.

[0317] According to the solution of the present application, when a CSI report includes multiple CSIs, relevant discarding or sending rules for CSI reference resources of each sub-configuration are defined, thereby ensuring normal CSI report reporting by the terminal device.

[0318] FIG10 is a schematic diagram of another CSI transmission method 300 provided in an embodiment of the present application. As shown in FIG10 , the method 300 includes at least the following steps:

[0319] S310, the network device sends first configuration information, and correspondingly, the terminal device receives the first configuration information.

[0320] The first configuration information indicates L sub-configurations, the first configuration information corresponds to a reference signal resource set, each of the L sub-configurations corresponds to at least one reference signal resource in the reference signal resource set, and L is a positive integer.

[0321] This step is similar to S210 in method 200 , and for details, please refer to the description of S210 above.

[0322] S320: Determine M second time domain resources.

[0323] The terminal device determines M second time domain resources based on the last reference signal resource in the time domain indicated by each subconfiguration in the M subconfigurations. The M second time domain resources correspond one-to-one to the M subconfigurations, and M is a positive integer less than or equal to L.

[0324] M sub-configurations belong to L sub-configurations.

[0325] It should be understood that when the CSI reporting configuration is a periodic CSI reporting configuration, the M sub-configurations are L sub-configurations; when the CSI reporting configuration is a semi-continuous CSI reporting configuration or a non-periodic CSI reporting configuration, the M sub-configurations are the sub-configurations triggered by the network device in the L sub-configurations.

[0326] In a possible implementation, the second time domain resource is separated from the last reference signal resource in the time domain indicated by the corresponding sub-configuration by a first value, where the first value is the CSI calculation time.

[0327] The first value may be preset or determined according to the first configuration information.

[0328] For example, the second time domain resource is T′ after the last symbol of the last reference signal resource in the time domain indicated by the sub-configuration to which it corresponds. proc,CSI =(Z′)(2048+144)·κ2 -μ ·T cThe next uplink OFDM symbol of the sub-configuration, the last reference signal resource in the time domain indicated by the sub-configuration can be the CSI-RS resource for channel measurement, or the CSI-RS resource for interference measurement, or the latest one of the CSI-IM resources for interference measurement, that is, the last resource in the time domain in the reference signal resource set and the second reference signal resource set.

[0329] In the above example, the first value is T′ proc,CSI The calculation formula of the first value can be preset or configured by the first configuration information, and then calculated according to the relevant values ​​configured in the first configuration information. In other embodiments, the first value can also be determined by preset, or can also be directly indicated by the first configuration information.

[0330] S340, the terminal device sends a second CSI report, and accordingly, the network device receives the second CSI report.

[0331] The second CSI report includes A third CSIs, which are updated according to the A third sub-configurations; the third CSI report also includes MA fourth CSIs that are not updated, and the MA fourth CSIs correspond to the MA fourth sub-configurations.

[0332] The second time domain resource corresponding to the third sub-configuration is earlier than the first CSI reporting resource in the time domain. The CSI reporting resource is indicated by the first configuration information, and A is a positive integer less than or equal to M.

[0333] In one possible implementation, MA fourth sub-configurations are determined from M sub-configurations based on M second time domain resources, and the MA fourth sub-configurations are other sub-configurations in the M sub-configurations except A third sub-configurations, and the second time domain resources corresponding to the fourth sub-configuration are later than the first CSI reporting resources in the time domain.

[0334] Exemplarily, as shown in Figure 11, subconfiguration 1 indicates CSI-RS resource #1, and subconfiguration 2 indicates CSI-RS resource #2. CSI-RS resource #1 is the last reference signal resource indicated by subconfiguration 1 in the time domain, and CSI-RS resource #2 is the last reference signal resource indicated by subconfiguration 2 in the time domain. The terminal device determines the second time domain resource 1 corresponding to subconfiguration 1 and the second time domain resource 2 corresponding to subconfiguration 2. The interval between CSI-RS resource #1 and the second time domain resource 1 in the time domain is the first value, and this interval is the CSI calculation time. The second time domain resource 1 is earlier than the first CSI reporting resource in the time domain, so subconfiguration 1 belongs to one of the A third subconfigurations, and the second time domain resource 2 is later than the first CSI reporting resource in the time domain, so subconfiguration 2 belongs to one of the MA fourth subconfigurations. Therefore, the terminal device does not need to update the CSI corresponding to subconfiguration 2.

[0335] In one possible implementation, the M CSIs may include a reference CSI, the reference CSI corresponds to a reference sub-configuration, the reference CSI may be one of the N first CSIs, and the MN second CSIs do not include the reference CSI. The reference CSI includes first information, the first information includes at least one of CRI, PMI, and RI, and the other CSIs in the N first CSIs except the reference CSI may not include the first information. Further, the terminal device determines the reference CSI in the M CSIs, the reference CSI is the CSI corresponding to the reference sub-configuration, and the reference sub-configuration is the first sub-configuration in the N first sub-configurations that meets at least one of the following conditions: the reference sub-configuration is the sub-configuration with the highest corresponding priority among the N first sub-configurations; or, the reference sub-configuration is the first sub-configuration with the lowest sub-configuration index among the N first sub-configurations; the reference sub-configuration is the sub-configuration with the largest number of ports of the CSI-RS resource among the N first sub-configurations. The reference sub-configuration is not included in the MN second sub-configurations. When the terminal device reports N first CSIs, it may report the N first CSIs in a compressed manner. For example, one uncompressed CSI and multiple compressed CSIs are reported, the uncompressed CSI includes the first information, and the compressed CSI does not include the first information. When the network device instructs the terminal device to report M CSIs, the terminal device needs to determine which CSI is not to be compressed. Since the terminal device will determine that MN second CSIs among the M CSIs will not be reported based on the relationship between the reference signal resources corresponding to the sub-configuration and the CSI reference resources, the terminal device needs to determine one of the first CSIs as the reference CSI based on the N first CSIs actually reported. The method for the terminal device to determine the reference CSI can refer to the aforementioned method.

[0336] In another possible implementation, when the M second time domain resources corresponding to the M sub-configurations are all earlier than the first CSI reporting resource in the time domain, the M sub-configurations are all third sub-configurations, that is, all M sub-configurations are updated. When any second time domain resource among the M second time domain resources corresponding to the M sub-configurations is later than the first CSI reporting resource in the time domain, the CSI corresponding to the M sub-configurations is discarded.

[0337] Optionally, the terminal device may execute S330 to determine A third sub-configurations from M sub-configurations according to the M second time domain resources.

[0338] According to the solution of the present application, when a CSI report includes multiple CSIs, relevant discarding or updating rules for the CSI calculation time of each sub-configuration are defined, thereby fully utilizing the CSI calculation capability of the terminal device.

[0339] As you can understand, CSI calculations for terminal devices involve various matrix operations, resulting in a very high computational load and complexity, significantly impacting the chip cost and power consumption of the terminal device. Furthermore, terminal devices using chips with different capabilities have varying CSI calculation capabilities. Therefore, CSI processing capabilities must be determined based on the CSI's processing capacity. If the number of available CPUs is less than the number of CPUs required for a single CSI report, the terminal device will not update the CSI report and will instead send an unupdated CSI report on the time-frequency resources used to transmit the CSI report.

[0340] FIG12 is a schematic diagram of another CSI transmission method 400 provided in an embodiment of the present application. As shown in FIG12 , the method 400 includes at least the following steps:

[0341] S410, the network device sends first configuration information, and correspondingly, the terminal device receives the first configuration information.

[0342] The first configuration information indicates L sub-configurations, the first configuration information corresponds to a reference signal resource set, each of the L sub-configurations corresponds to at least one reference signal resource in the reference signal resource set, the reference signal resource is used for channel measurement, and L is a positive integer.

[0343] This step is similar to S210 in method 200 , and for details, please refer to the description of S210 above.

[0344] S420: Determine the number P of available CSI processing units CPU within the first time unit.

[0345] In one OFDM symbol, if T CPUs are occupied, then N CPU -T CPUs are not occupied, that is, the number of available CPUs P = N CPU -T. Where N CPU The maximum number of CPUs supported by the terminal device, N CPU Reported by the terminal device.

[0346] S440, the terminal device sends a third CSI report, and accordingly, the network device receives the third CSI report

[0347] The third CSI report includes B fifth CSIs and MB sixth CSIs, the B fifth CSIs are updated according to the B fifth sub-configurations, and the MB sixth CSIs correspond to the MB sixth sub-configurations.

[0348] M sub-configurations belong to L sub-configurations. It should be understood that when the CSI reporting configuration is a periodic CSI reporting configuration, the M sub-configurations are the L sub-configurations; when the CSI reporting configuration is a semi-continuous CSI reporting configuration or a non-periodic CSI reporting configuration, the M sub-configuration is the sub-configuration triggered by the network device in the L sub-configurations.

[0349] The sum of the number of CPUs corresponding to the B fifth sub-configurations is less than or equal to the number of available CPUs P, that is, B satisfies the formula: is the number of CPUs corresponding to the n+1th sub-configuration after sorting the M sub-configurations by priority, that is, The number of CPUs required for the terminal to calculate the CSI of the (n+1)th sub-configuration after the M sub-configurations are prioritized.

[0350] The priorities corresponding to B fifth sub-configurations are higher than the priorities corresponding to MB sixth sub-configurations, M is a positive integer less than or equal to L, and B is an integer less than or equal to M.

[0351] It should be understood that the sum of the number of CPUs corresponding to the B fifth sub-configurations and the number of CPUs corresponding to any one sixth sub-configuration is greater than the number of available CPUs P. In other words, B satisfies the formula: The largest positive integer, is the number of CPUs corresponding to the n+1th sub-configuration after sorting the M sub-configurations by priority, that is, The number of CPUs required for the terminal to calculate the CSI of the (n+1)th sub-configuration after the M sub-configurations are prioritized.

[0352] The number of CPUs corresponding to a subconfiguration may be equal to the number of reference resources for channel measurement included in the subconfiguration. That is, the number of CPUs required to calculate the CSI of the subconfiguration may be equal to the number of reference resources for channel measurement included in the subconfiguration. For example, if a subconfiguration includes two reference resources for channel measurement, the number of CPUs corresponding to the subconfiguration is equal to two.

[0353] In another possible implementation, when the number of CPUs corresponding to the M sub-configurations is less than or equal to the number of available CPUs P, the CSI corresponding to all M sub-configurations is sent / updated; when the number of CPUs corresponding to the M sub-configurations is greater than the number of available CPUs P, the CSI corresponding to all M sub-configurations is discarded / not updated.

[0354] In one possible implementation, when the third CSI report is a semi-persistent CSI report sent on the PUSCH for the first time, the number of CPUs corresponding to the M sub-configurations is determined based on the CSI-RS resources used for channel measurement included in the L sub-configurations, where M is less than or equal to L. That is, the number of CPUs required for calculating the CSI of the M sub-configurations is equal to the sum of the CSI-RS resources used for channel measurement included in the L sub-configurations. For example, if L=3 and M=2, and each sub-configuration includes 2 CSI-RS resources used for channel measurement, then the number of CPUs corresponding to the M sub-configurations is 6. When the third CSI report is a semi-persistent CSI report sent on the PUSCH other than the semi-persistent CSI report sent on the PUSCH for the first time, the number of CPUs corresponding to the M sub-configurations is determined based on the CSI-RS resources used for channel measurement included in the M sub-configurations. That is, the number of CPUs required for calculating the CSI of M sub-configurations is equal to the sum of the CSI-RS resources for channel measurement included in the M sub-configurations. For example, L = 3, M = 2, each sub-configuration includes 2 CSI-RS resources for channel measurement, then the number of CPUs corresponding to the M sub-configurations is equal to 4.

[0355] In one possible implementation, when the third CSI report is a non-periodic CSI report, the number of CPUs corresponding to the M sub-configurations is determined based on the CSI-RS resources for channel measurement included in the M sub-configurations, that is, the number of CPUs required to calculate the CSI of the M sub-configurations is equal to: the sum of the CSI-RS resources for channel measurement included in the M sub-configurations, for example, L=3, M=2, each sub-configuration includes 2 CSI-RS resources for channel measurement, then the number of CPUs corresponding to the M sub-configurations is equal to 4.

[0356] In one possible implementation, the number of CPUs corresponding to the B fifth sub-configurations is determined based on the number of CSI-RS resources for channel measurement included in the B sub-configurations. If the sub-configuration includes one CSI-RS resource for channel measurement, one CPU is occupied; if the sub-configuration includes two CSI-RS resources, two CPUs are occupied, and so on.

[0357] In a possible implementation, the priority of a sub-configuration is determined according to an index of the sub-configuration, and a sub-configuration with a smaller index has a higher priority.

[0358] Optionally, the terminal device may execute S430 to determine B fifth sub-configurations and MB sixth sub-configurations according to the number P of available CPUs, the number of CPUs corresponding to the M sub-configurations, and the priorities corresponding to the M sub-configurations.

[0359] According to the solution provided in this application, when the CSI report includes multiple CSIs, CPU-related discarding or updating rules for each sub-configuration are defined, and it is ensured that the terminal device can fully utilize the CSI reporting resources and computing power.

[0360] FIG13 is a schematic diagram of another CSI transmission method 500 provided in an embodiment of the present application. As shown in FIG13 , the method 500 includes at least the following steps:

[0361] S510, the network device sends first configuration information and second configuration information, and correspondingly, the terminal device receives the first configuration information and the second configuration.

[0362] The first configuration information indicates L sub-configurations and a first CSI reporting resource, where each first sub-configuration indicates at least one reference signal resource in a reference signal resource set; the second configuration information indicates a second CSI reporting resource, where the first CSI reporting resource is used to report a first CSI report, and the second CSI reporting resource is used to report a second CSI report, where L is a positive integer.

[0363] S520: Determine a first CSI report and a second CSI report.

[0364] A first CSI report is determined according to the first configuration information, where the first CSI report includes L seventh CSIs, the L seventh CSIs are determined according to the L sub-configurations, and the seventh CSI includes L first parts and L second parts. The L first parts indicate at least one of a rank indication RI, a resource indication CRI, and a channel quality indication CQI of a first codebook, and the L second parts indicate any one of a wideband CQI, a wideband layer indication LI, a wideband precoding matrix indication PMI, and a subband CSI of a second codebook; and a second CSI report is determined according to the second configuration information.

[0365] In a possible implementation, the priority corresponding to the second CSI report is higher than the priority corresponding to the first CSI report. It should be understood that the priority of the CSI report can be determined according to the aforementioned priority calculation method.

[0366] S530: Determine a third CSI reporting resource.

[0367] When the first CSI reporting resource and the second CSI reporting resource are located in the same carrier and include the same time domain resource, the third CSI reporting resource is determined according to the third configuration information.

[0368] That is, when two CSI reports conflict, another CSI reporting resource will be determined. The third configuration information may be indicated by the network device or pre-configured, and this application does not limit this.

[0369] S540: The terminal device sends a second CSI report and a third CSI report, and correspondingly, the network device receives the second CSI report and the third CSI report.

[0370] The second CSI report and the third CSI report are sent on the third CSI reporting resource, and the third CSI report is determined according to the priority order of the L first parts and the L second parts.

[0371] Since the priority of the second CSI report is higher than that of the first CSI report, the second CSI report will be sent in full. The third CSI report is determined based on the priorities of the two parts of the first CSI report, so the third CSI report belongs to the first CSI report and is part of the information of the first CSI report.

[0372] In one possible implementation, the L second parts include L wideband CSIs and L subband CSIs. The priority of the L wideband CSIs is higher than the priority of the L subband CSIs. The priority order of the L subband CSIs is determined based on the priorities corresponding to the L subconfigurations. The subband CSIs include odd-numbered subband CSIs and even-numbered subband CSIs, with odd-numbered subband CSIs having a higher priority than even-numbered subband CSIs. That is, the priority of CSI part 2 is ordered as follows: L wideband part 2 CSIs, part 2 subband CSIs of the odd subbands of the highest-priority subconfiguration, part 2 subband CSIs of the even subbands of the highest-priority subconfiguration, part 2 subband CSIs of the odd subbands of the next-highest-priority subconfiguration, part 2 subband CSIs of the even subbands of the next-highest-priority subconfiguration, and so on.

[0373] In another possible implementation, the L second parts include L wideband CSI, L odd subband CSI, and L even subband CSI. The priority of the L wideband CSI is higher than the priority of the L odd subband CSI, and the priority of the L odd subband CSI is higher than the priority of the L even subband CSI. The priority order of the L odd subband CSI is determined according to the priorities corresponding to the L subconfigurations, and the priority order of the L even subband CSI is determined according to the priorities corresponding to the L subconfigurations. That is, the priority of part 2 of the CSI is ordered as follows: L wideband part 2 CSI, part 2 subband CSI of the odd subband of the highest priority subconfiguration, part 2 subband CSI of the odd subband of the second highest priority subconfiguration, and so on, part 2 subband CSI of the even subband of the highest priority subconfiguration, part 2 subband CSI of the even subband of the second highest priority subconfiguration, and so on.

[0374] It should be understood that the priorities corresponding to the L sub-configurations can be determined according to the index corresponding to each sub-configuration.

[0375] According to the solution of the present application, when a CSI report includes multiple CSIs, if the reporting resources of two CSI reports overlap, a rule is defined for discarding the CSI corresponding to each sub-configuration based on the priority corresponding to each sub-configuration, so that the reporting resources can be fully utilized and the reporting of important CSI is guaranteed.

[0376] FIG14 is a schematic diagram of another CSI transmission method 600 provided in an embodiment of the present application. As shown in FIG14 , the method 600 includes at least the following steps:

[0377] S610, the network device sends first configuration information and second configuration information, and correspondingly, the terminal device receives the first configuration information and the second configuration information.

[0378] The first configuration information indicates L sub-configurations and a first CSI reporting resource, where each first sub-configuration indicates at least one reference signal resource in a reference signal resource set; the second configuration information indicates a second CSI reporting resource, where the first CSI reporting resource is used to report a first CSI report, and the second CSI reporting resource is used to report a second CSI report, where L is a positive integer.

[0379] During configuration, the network device can ensure that the first CSI reporting resources and the second CSI reporting resources do not overlap in the time domain. That is, the resources of the two CSI reports can be specified to not include overlapping time domain resources. In this case, there will be no conflict between the two CSI reports. Alternatively, it can be specified that a CSI report including L sub-configurations cannot include overlapping time domain resources with any other CSI report. Overlapping time domain resources can be understood as the same OFDM symbol or the same time slot.

[0380] S620: Determine a first CSI report and a second CSI report.

[0381] S630, the terminal device sends a first CSI report on the first CSI reporting resource and sends a second CSI report on the second CSI reporting resource. Correspondingly, the network device receives the first CSI report and the second CSI report.

[0382] According to the solution of the present application, when a CSI report includes multiple CSIs, it can be ensured that reporting resources of the CSI report do not conflict, thereby improving the stability of communication.

[0383] FIG15 is a schematic diagram of another CSI transmission method 700 provided in an embodiment of the present application. As shown in FIG15 , the method 700 includes at least the following steps:

[0384] S710, the network device sends first configuration information, and correspondingly, the terminal device receives the first configuration information.

[0385] The first configuration information indicates L sub-configurations, and the first configuration information corresponds to a reference signal resource set. The reference signal set includes a first CSI-RS resource, and the first CSI-RS resource includes H CSI-RS ports. Each of the G sub-configurations includes the first indication information, and the G sub-configurations belong to the L sub-configurations. The first indication information of the g-th sub-configuration indicates J CSI-RS ports among the H CSI-RS ports of the first CSI-RS resource. The reference signal resources for channel measurement corresponding to the g-th sub-configuration are the resources included in the J CSI-RS ports in the first CSI-RS resource. L, H, G, and K are positive integers. The reference signal resources for channel measurement corresponding to the g-th sub-configuration can be understood as reference signal resources used to calculate the CSI corresponding to the g-th sub-configuration.

[0386] The reference signal set includes at least one second CSI-RS resource, the second CSI-RS resource includes H CSI-RS ports, each of the G subconfigurations includes first indication information, the first indication information of the g-th subconfiguration indicates J CSI-RS ports among the H CSI-RS ports of each second CSI-RS reference resource in the at least one second CSI-RS resource, the reference signal resources for channel measurement corresponding to the g-th subconfiguration are the resources included in the J CSI-RS ports of each second CSI-RS reference resource in the at least one second CSI-RS resource, and L, H, G, and K are positive integers. The reference signal resources for channel measurement corresponding to the g-th subconfiguration can be understood as reference signal resources used to calculate the CSI of the g-th subconfiguration.

[0387] S720: Determine the number of activated CSI-RS resources and the number of activated CSI-RS ports according to the first configuration information.

[0388] In one possible implementation, when determining to activate CSI-RS resources, the number of activated CSI-RS resources determined based on the first configuration information and the first CSI-RS resources is equal to the number of first CSI-RS resources, and when activating the number of CSI-RS ports, the number of activated CSI-RS ports determined based on the first configuration information and the first CSI-RS resources is equal to the sum of J ports indicated by the L sub-configurations. Exemplarily, the first CSI-RS resource includes H=32 CSI-RS ports, L=2 sub-configurations, numbered sub-configuration 1 and sub-configuration 2, the first indication information in sub-configuration 1 indicates 16 ports out of 32 ports, and the first indication information in sub-configuration 2 indicates 8 ports out of 32 ports. When calculating the activated CS-RS resources, the activated CSI-RS resources are determined to be equal to the number of the first CSI-RS resources as 1 according to the first configuration information and the first CSI-RS resources. When calculating the activated CSI-RS ports, the number of activated CSI-RS ports determined according to the first configuration information and the first CSI-RS resource is equal to the sum of J ports indicated by the L sub-configurations, that is, 16+8=24 activated CSI-RS ports.

[0389] In another possible implementation, when determining activated CSI-RS resources, the activated CSI-RS resources are determined to be equal to the number of first CSI-RS resources based on the first configuration information and the first CSI-RS resources. When determining the number of activated CSI-RS ports, the number of activated CSI-RS ports determined based on the first configuration information and the first CSI-RS resources is equal to the maximum value of J indicated by the L sub-configurations. Exemplarily, the first CSI-RS resources include H=32 CSI-RS ports, L=2 sub-configurations, numbered sub-configuration 1 and sub-configuration 2, the first indication information in sub-configuration 1 indicates 16 of the 32 ports, and the first indication information in sub-configuration 2 indicates 8 of the 32 ports. In this case, when calculating the activated CSI-RS resources, the first CSI-RS resources are calculated once, and when calculating the activated CSI-RS ports, only the 16 CSI-RS ports of sub-configuration 1 are calculated.

[0390] In another possible implementation, L CSIs are determined based on L sub-configurations. If one of the L CSIs includes first information and L CQIs, and the first information includes at least one of a first CRI and a first PMI, when determining the activated CSI-RS resources, the number of activated CSI-RS resources determined based on the first configuration information is equal to the sum of the number of first reference resources, the number of at least one second reference resources, and L-1. When determining the number of activated CSI-RS ports, the number of activated CSI-RS resources determined based on the first configuration information is equal to the total number of ports indicated by the reference sub-configuration from the first reference resource and the at least one second reference resource, and the sum of J indicated by each of the other L-1 sub-configurations excluding the reference sub-configuration. The reference sub-configuration can be the sub-configuration with the largest J, or the self-configuration with the lowest index. For example, the first CSI-RS resource includes H=32 CSI-RS ports, a total of 1 second CSI-RS resource includes 32 ports, L=2 sub-configurations, numbered sub-configuration 1 and sub-configuration 2, the first indication information in sub-configuration 1 indicates 16 ports out of 32 ports, and the first indication information in sub-configuration 2 indicates 8 ports out of 32 ports. When calculating the activated CS-RS resources, the number of activated resources determined according to the first configuration information is 2+1=3, and when calculating the activated CSI-RS ports, the number of activated resources determined according to the first configuration information is 16*2+8=40. Optionally, the first CRI is the index of a third CSI-RS in the first CSI-RS resource and at least one second CSI-RS resource, the L CQIs are determined by the L fourth CSI-RS resources, and the L fourth CSI-RS resources are determined from the third CSI-RS resource based on the L first indication information, that is, the fourth CSI-RS resource is the resource corresponding to J ports in the third CSI-RS resource, the L fourth CSI-RS resources are included in the activated CSI-RS resources determined according to the first configuration information, and the ports of the L fourth CSI-RS resources are included in the activated CSI-RS ports determined according to the first configuration information. Optionally, L-1 fifth CSI-RS resources are not included in the activated CSI-RS resources determined according to the first configuration information (which can be understood as not being counted in the activated CSI-RS resources determined according to the first configuration information), and the ports of the L-1 fifth CSI-RS resources are not included in the activated CSI-RS ports determined according to the first configuration information (which can be understood as not being counted in the activated CSI-RS ports determined according to the first configuration information). The fifth CSI-RS resources include the resources included in the J ports of the sixth CSI-RS resource indicated by the first indication information in any sub-configuration of the M sub-configurations except the reference sub-configuration. The sixth CSI-RS resource is any one of the first CSI-RS resource and at least one second CSI-RS resource except the third CSI-RS.

[0391] According to the solution of the present application, a method is provided for a terminal to determine the number of activated CSI-RS resources and activated CSI-RS ports, which is conducive to the terminal and the network device to have the same understanding of the number of activated CSI-RS resources and activated CSI-RS ports, so that the network device will not configure the number of CSI-RS resources and the number of CSI-RS ports that exceed the terminal capability limit.

[0392] According to the aforementioned method, FIG16 is a schematic diagram of a wireless communication device 800 provided in an embodiment of the present application.

The memory is primarily used to store software programs and data, such as the codebook described in the above embodiment. The control circuit is primarily used to convert baseband signals into radio frequency signals and process radio frequency signals. The control circuit and antenna together are also called a transceiver, which is primarily used to transmit and receive radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, displays, and keyboards, are primarily used to receive user input and output data to the user.

[0442] When the communication device is powered on, the processor reads the software program stored in the storage unit, interprets and executes the software program's instructions, and processes the software program's data. When data needs to be sent wirelessly, the processor performs baseband processing on the data to be transmitted and outputs the baseband signal to the RF circuit. The RF circuit then performs RF processing on the baseband signal and transmits it outward in the form of electromagnetic waves via the antenna. When data is sent to a terminal device, the RF circuit receives the RF signal via the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data.
