Description

Communication method and related apparatus

[0001] This application claims priority to the Chinese patent application No. 202410572420.0, filed on May 9, 2024, and entitled "A communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to a communication method and related apparatus. BACKGROUND

[0003] In order to provide any data channel in uplink (UL) or downlink (DL) transmission on PDSCH or PUSCH of a communication system, a network device sends a reference signal to a terminal device. The reference signal is used by the terminal device to perform channel / signal estimation / measurement for demodulating PDCCH and other common channels, and some measurements and feedbacks, which is the common / cell-specific reference signal (CRS) inherited from the Evolved Universal Terrestrial Radio Access (E-UTRA) Release 8 / 9 specification. Dedicated / demodulation reference signal (DMRS) can be transmitted together with PDSCH channel in E-UTRA Release 10. DMRS is used for channel estimation in the PDSCH demodulation process. In Release 10, in addition to CRS and DMRS, channel state information reference signal (CSI-RS) is also introduced.

[0004] The terminal device perceives the state of the channel carrying the reference information by receiving and measuring the reference information sent by the network side, and generates a corresponding channel state information (CSI) measurement report to return to the network device, so that the network device has actual perception of the state of the channel.

[0005] In a poor communication scenario, for example, a scenario in which a satellite communicates with a terminal, there is a scenario in which a Non-terrestrial Network (NTN) transmission delay is very large. A situation in which the actual conflict occurring at the terminal does not match the conflict considered by the base station may occur. In particular, for a half-duplex terminal, the uplink and downlink cannot be performed at the same time. When the network equipment (satellite) sends reference information to such a terminal, a situation in which uplink information with a higher priority conflicts with the reference information may occur in such a terminal, causing the terminal device to be unable to accept the reference information, and thus unable to measure the reference information. In the existing protocol standard, when the terminal device faces such a situation, the pre-applied measurement / computation resources cannot be used, resulting in resource waste. SUMMARY

[0006] The present application provides a communication method and related apparatus, which generates a measurement report of other reference signals by using resources pre-configured for the conflicting reference signals, thereby reducing resource waste.

[0007] In a first aspect, the present application provides a communication method, which can be applied to the terminal side, such as a terminal device or a communication module in the terminal device, or a circuit or chip responsible for communication functions in the terminal device (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core). Taking the case of applying the method to a terminal device, the method includes:

[0008] determining that a first reference signal conflicts with other signals;

[0009] generating a channel state information (CSI) measurement report of a second reference signal by using a first calculation resource, wherein the first calculation resource is a resource pre-determined for generating a CSI measurement report of the first reference signal.

[0010] First, the reference signal and the CSI measurement report are briefly introduced. In the existing LTE system (e.g., Rel. 10-15), a reference signal for measuring the channel state in the downlink is specified. The reference signal for channel state measurement is also referred to as a cell-specific reference signal (CRS), a channel state information-reference signal, or a reference signal used in the measurement of CSI such as a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and the like.

[0011] The terminal device UE feeds back the result measured based on the reference signal for channel state measurement (e.g., CSI-RS) to the base station (may also be a network, eNB, gNB, transmission reception point, etc.) as channel state information (CSI). In the existing system (e.g., Rel. 15), as a feedback method of CSI, a periodic CSI report (P-CSI), a CSI report using a resource specified semi-permanently (Semi-Persistent-Channel State Information, SP-CSI), and an aperiodic CSI report (A-CSI) are specified. It should be understood that the functions and specific examples of the reference signal listed above are only illustrative and should not constitute any limitation on the present application, and the present application does not exclude the possibility of defining other functions or uses of the reference signal in future protocols.

[0012] The method provided by the embodiments of the present application is mainly for terminal devices in a scenario where reference signals collide, especially for half-duplex terminal devices that may collide with uplink signals. When such terminal devices face a collision between a reference signal and a high-priority uplink signal, the terminal device may not be able to accept and measure the reference signal due to the need to send the high-priority uplink signal, resulting in the inability to update the CSI report corresponding to the reference signal. However, for a CSI measurement report (for example, a periodic CSI measurement report), there may be multiple reference signals that need to be measured. In the existing standard, the terminal device will still send a corresponding CSI measurement report for the reference signal that cannot be measured, but the CSI measurement report is not updated, which means that the terminal device does not need to consume resources for measuring the reference signal when generating the CSI measurement report, which undoubtedly wastes resources. Therefore, in the embodiments of the present application, by reallocating the first calculation resource for generating the CSI measurement report of the first reference signal (the reference signal that collides with the uplink signal) to the second reference signal, resource multiplexing is achieved, resource waste is avoided, resource use efficiency is improved, and accordingly, the flexibility and adaptability of the communication system are enhanced, so that the system can better adapt to complex communication environments.

[0013] In yet another optional implementation of the first aspect, the priority of the CSI measurement report of the second reference signal is lower than the priority of the CSI measurement report of the first reference signal.

[0014] Optionally, the priority of the CSI measurement report of the second reference signal is lower than and closest to the priority of the CSI measurement report of the first reference signal.

[0015] In yet another optional implementation of the first aspect, the method further comprises:

[0016] The CSI measurement report of the second reference signal is sent through the first time-frequency resource, which is a resource pre-configured for sending the CSI measurement report of the first reference signal.

[0017] In the prior art, the sending order of the CSI measurement report is determined by the terminal according to the priority of the pre-configured CSI measurement report. The priority of the CSI measurement report of the second reference signal is lower than the priority of the CSI measurement report of the first reference signal, which means that the sending time of the CSI measurement report of the second reference signal is later than the sending time of the CSI measurement report of the first reference signal. The present embodiment clearly shows that by adjusting the priority of the CSI measurement report, the resource waste caused by the collision can be flexibly solved when the reference signals collide, the network device is prevented from receiving the CSI measurement report of the first reference signal without updating, the continuity and stability of the communication are ensured, and the robustness of the system is improved.

[0018] Secondly, the CSI measurement report of the second reference signal is transmitted by sharing the first time-frequency resource, which realizes resource multiplexing, significantly improves the utilization rate of resources, reduces the communication cost, and uses preconfigured resources for communication, simplifies the operation process of the network side and the terminal side, reduces the complexity of the communication system, and improves the reliability and maintainability of the system.

[0019] In yet another optional implementation of the first aspect, the CSI measurement report of the second reference signal includes an index ID.

[0020] In the present embodiment, by setting an index ID for the CSI measurement report of the second reference signal, the network device receiving the CSI measurement report can clearly use the first time-frequency resource to transmit the CSI measurement report of the first reference signal, rather than other CSI measurement reports, thereby avoiding the cost waste of the network device due to misidentification.

[0021] In yet another optional implementation of the first aspect, the method further comprises:

[0022] determining a reporting queue of the CSI measurement report, the reporting queue being obtained by sorting in descending order of priority of the CSI measurement report; the reporting queue includes the first CSI measurement report and the second CSI measurement report, and the priority of the first CSI measurement report is higher than the priority of the second CSI measurement report;

[0023] when the first CSI measurement report in the reporting queue and at least one downlink signal from the network device conflict, updating the reporting queue to obtain an updated reporting queue, and the priority of the first CSI measurement report in the updated reporting queue is lower than the priority of the second CSI measurement report.

[0024] In the present embodiment, the CSI measurement report is orderly managed by the reporting queue, which ensures the orderliness and efficiency of information reporting and reduces the complexity of data processing.

[0025] Further, when a conflict occurs, the priority of the measurement report in the reporting queue is adjusted to efficiently handle the conflict, ensure the continuity and stability of communication, and improve the performance and reliability of the system. Optionally, for the reference signal that conflicts, a conflict identifier is appended to the CSI measurement report (e.g., the first CSI measurement report) of the reference signal that conflicts, and the conflict identifier is used to represent that the reference signal corresponding to the CSI measurement report conflicts, and the CSI measurement report is not updated.

[0026] In yet another optional implementation of the first aspect, the method further comprises:

[0027] determining a reporting queue of CSI measurement reports, the reporting queue being sorted in descending order of priority of the CSI measurement reports; the reporting queue including a first CSI measurement report and a second CSI measurement report, the priority of the first CSI measurement report being higher than the priority of the second CSI measurement report;

[0028] when the first CSI measurement report corresponding to the reference signal conflicts with an uplink signal sent by at least one terminal, updating the reporting queue to obtain an updated reporting queue, the priority of the first CSI measurement report in the updated reporting queue being lower than the priority of the second CSI measurement report.

[0029] For the first CSI measurement report that conflicts with the uplink signal, the sending order of the first CSI measurement report is changed by adjusting the reporting queue to avoid the conflict, and optionally, the priority of the uplink signal is higher than the priority of the first CSI measurement report.

[0030] In yet another alternative implementation of the first aspect, the method further comprises:

[0031] deleting the CSI measurement report of the first reference signal from the reporting queue;

[0032] The sending of the CSI measurement report of the second reference signal through the first time-frequency resource comprises:

[0033] The CSI measurement report of the second reference signal ranked first in the reporting queue is sent through the first time-frequency resource.

[0034] By deleting the CSI measurement report of the first reference signal that conflicts from the reporting queue, the reporting logic of the measurement report is optimized, and the situation that the network device wastes resources in analyzing useless information (no updated CSI measurement report) sent to the network device is avoided. It should be noted that the CSI measurement report of the second reference signal ranked first in the reporting queue is because the CSI measurement report of the first reference signal has been deleted from the reporting queue.

[0035] In yet another alternative implementation of the first aspect, the method further comprises:

[0036] generating other CSI measurement reports in the reporting queue according to the processing capability and the reporting queue.

[0037] In an embodiment, the processing capability is used to represent the CPU capability of the terminal device, and the processing capability herein includes computing capability, sending capability, etc. For example, if the terminal has a conflict of first reference signal measurement, the terminal cannot measure the corresponding first reference signal, and the terminal does not update the corresponding CSI measurement report. In this case, the terminal can continue to measure and update the remaining highest priority CSI measurement report according to the CPU capability. For example, the terminal has a conflict of 2 high priority CSI reports, and the capability of the terminal is to report N CSI reports, and there are M CSI reports in total, then the terminal still reports M CSI reports, including N updated conflict-free and high priority CSI reports. Through the above implementation process, the terminal capability is used to update the possible updated CSI measurement report as much as possible.

[0038] In a second aspect, the present application provides a communication method, comprising:

[0039] sending a first reference signal;

[0040] receiving a CSI measurement report of a second reference signal on a first time-frequency resource, wherein the first time-frequency resource is a pre-configured resource for sending the CSI measurement report of the first reference signal, and the first reference signal has a conflict with other signals.

[0041] It should be noted that the network also sends the second reference signal after / before sending the first reference signal.

[0042] The present embodiment is mainly for a network device. In the existing protocol standard, in the scenario of reference signal conflict, the network device receives the CSI measurement report of the first reference signal on the first time-frequency resource. However, the CSI measurement report of the first reference signal is a non-updated measurement report due to the conflict, which is meaningless to the network device. Therefore, the CSI measurement report of the second reference signal received on the first time-frequency resource (reference signal without conflict) is an updated measurement report, which does not waste the related resources preset by the network device. Optionally, the CSI measurement report of the second reference signal further includes an index ID.

[0043] In a third aspect, the present application provides a communication method, comprising:

[0044] determining that a physical uplink data channel (PUSCH) of a third CSI measurement report has a conflict with a PUSCH of a fourth CSI measurement report;

[0045] transmit the first content through the PUSCH, wherein the first content comprises a CSI measurement report corresponding to a reference signal without conflict in the third CSI measurement report and the fourth CSI measurement report, or the first content comprises the third CSI measurement report and the fourth CSI measurement report.

[0046] In the existing standards, the following protocol standards are provided for the conflict of PUSCH:

[0047] If two PUSCHs conflict with each other and both of them carry CSI measurement reports, the terminal will determine which PUSCH not to send according to the priority of the CSI measurement report carried by the PUSCH. However, in actual situations, the PUSCH carrying the CSI measurement report with high priority may conflict with the corresponding downlink reference signal, resulting in that the report with high priority cannot be measured and updated, and the discarded PUSCH carrying the CSI measurement report with low priority also causes the network side to not receive the updated CSI measurement report (the CSI measurement report with low priority but without conflict of reference signal).

[0048] Therefore, in the embodiment, if the CSI reporting corresponding to one PUSCH is limited by CPU or the measurement of the reference signal is conflicted, the terminal needs to comprehensively consider the CSI measurement conflict, the CSI priority and the conflict of the PUSCH carrying the CSI to determine the CSI reporting. Alternatively, if the reference signal corresponding to the CSI measurement and reporting with high priority conflicts with the uplink and downlink, resulting in that the terminal cannot update the corresponding CSI measurement report, when the PUSCH carrying the CSI measurement reporting and the PUSCH with low priority conflict with each other, the terminal reports and updates the CSI measurement report with low priority. By determining the conflict of the third CSI measurement report and the fourth CSI measurement report, and transmitting the first content containing only the non-conflicted CSI measurement report on the PUSCH, the loss or delay of the measurement report caused by the resource conflict is effectively avoided, the completeness and timeliness of the measurement report are ensured, the communication resources are maximized, and the communication efficiency is improved.

[0049] Further, when the first content comprises the third CSI measurement report and the fourth CSI measurement report, it is indicated that the PUSCHs conflict with each other and both of them carry CSI measurement reports, and the terminal can combine the contents of the two PUSCHs and report them together, thereby saving resources and avoiding the conflict.

[0050] In another optional embodiment of the third aspect, the first content comprises an index ID, and the index ID is used to represent the ID of the CSI measurement report contained in the first content.

[0051] The embodiment of the present application makes the network side and the terminal clearly identify the ID of the CSI measurement report contained in the first content by including the index ID in the first content, so as to facilitate subsequent data processing and analysis. The explicit index ID helps the network side quickly locate and process the required CSI measurement report, thereby improving the data processing efficiency.

[0052] In another optional implementation of the third aspect, if the first content includes the third CSI measurement report and the fourth CSI measurement report, the start point of the first content is determined according to the PUSCH of the third CSI measurement report and the PUSCH of the fourth CSI measurement report with the earlier timing.

[0053] The embodiment of the present application determines the start point of the first content according to the PUSCH start point with the earlier timing, thereby simplifying the processing flow of the terminal when sending the first content and reducing the implementation complexity. Further, the sending of the first content is started according to the earlier PUSCH start point, so that the sending of the measurement report can be completed earlier, thereby improving the time utilization.

[0054] In another optional implementation of the third aspect, the method further includes:

[0055] determining that there is a conflict between the reference signal corresponding to the third CSI measurement report and the reference signal corresponding to the fourth CSI measurement report.

[0056] In another optional implementation of the third aspect, the first content includes the CSI measurement report in which the corresponding reference signal does not conflict in the third CSI measurement report and the fourth CSI measurement report.

[0057] In a fourth aspect, the present application provides a communication method, including:

[0058] sending a third reference signal and a fourth reference signal;

[0059] receiving a first content, wherein the first content includes the CSI measurement report in which the corresponding reference signal does not conflict in the third CSI measurement report and the fourth CSI measurement report, or the first content includes the third CSI measurement report and the fourth CSI measurement report; there is a conflict between the PUSCH of the third CSI measurement report and the PUSCH of the fourth CSI measurement report, the third CSI measurement report is sent by the terminal according to the third reference signal, and the fourth CSI measurement report is sent by the terminal according to the fourth reference signal.

[0060] The embodiment of the present application is applied to a network device side. The network device receives a first content containing a non-conflict CSI measurement report sent by a terminal, and ensures the completeness and accuracy of the received measurement report.

[0061] In another alternative implementation of the fourth aspect, the first content includes an index ID, and the index ID is used to represent an ID of the measurement report contained in the first content.

[0062] In another alternative implementation of the fourth aspect, the first content includes the third CSI measurement report and the fourth CSI measurement report, and the corresponding reference signals of the third CSI measurement report and the fourth CSI measurement report are all non-conflict.

[0130] First, CSI measurement reporting is introduced:

[0131] CSI measurement reporting can be configured as:

[0132] 1. Periodic CSI reporting (P-CSI): only transmitted on a physical uplink control channel (PUCCH);

[0133] 2. Semi-Persistent CSI reporting (SP-CSI): transmitted on PUCCH or Physical Uplink Shared Channel (PUSCH). PUSCH-based SP-CSI reporting is activated and deactivated by CSI request field (CSIRequest) in Downlink Control Information (DCI) signaling, and RRC configures maximum 64 trigger states (TriggerState), each of which corresponds to one CSI reporting feedback configuration (CSIReportSetting). For CSI acquisition, each CSIReportSetting is associated with only one CSI-RS resource set in the corresponding Resource Setting;

[0134] 3. Aperiodic CSI reporting (A-CSI): transmitted only on PUSCH. PUSCH-based A-CSI reporting is activated by DCI signaling, and RRC configures multiple trigger states (TriggerState), each of which corresponds to one or more CSI reporting feedback configurations (CSIReportSetting). CSI request field (CSIRequest) in DCI triggers one TriggerState, and the maximum number of CSI trigger states supported is 64, because the maximum number of CSI request field in DCI format 0_1 is 6 bits. When the number of CSI trigger states configured by RRC is greater than 64, MAC CE signaling is used to map 64 trigger states to the CSI request field. Each CSI trigger state can be associated with 1-3 resource settings, and if a resource setting contains multiple resource sets, only one resource set is selected. The quasi co-location (QCL) information of the CSI-RS resources in this resource set is indicated by the transmission configuration indicator (TCI) state for each resource configuration.

[0135] The architecture of the communication system involved in the present application will be introduced below.

[0136] As shown in FIG. 1, FIG. 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application.

[0147] In an optional embodiment, please refer to FIG. 2, which is a schematic diagram of an architecture of a communication system provided by an embodiment of the present application. The communication system includes one or more terminal devices, one or more 5G base stations, a ground station, and a 5G core network.

[0148] The terminal device accesses the satellite network through 5G new air interface, the 5G base station is deployed on the satellite, and is connected to the 5G core network on the ground through a wireless link. At the same time, there is a wireless link between the satellites to complete the signaling interaction and user data transmission between the base stations. In this embodiment, the terminal device is a mobile device supporting 5G new air interface, such as a mobile phone, a pad, and the like. The mobile device can access the satellite network through 5G new air interface and initiate a call, access the Internet, and the like. 5G new air interface is used to refer to the wireless link between the terminal and the base station.

[0149] The 5G base station mainly provides wireless access services, schedules wireless resources to access terminals, and provides reliable wireless transmission protocols and data encryption protocols, and the like. The 5G base station in this embodiment is deployed on the satellite. The communication between the 5G base stations is mainly through the Xn interface, and the Xn interface is mainly used for signaling interaction such as handover.

[0150] The 5G core network mainly supports user access control, mobility management, session management, user security authentication, charging, and the like. It is composed of multiple functional units, which can be divided into functional entities of the control plane and the data plane. The access and mobility management unit (AMF) is responsible for user access management, security authentication, and mobility management. The user plane unit (UPF) is responsible for managing the transmission of user plane data, traffic statistics, and the like. The ground station is responsible for forwarding the signaling and service data between the satellite base station and the 5G core network. The 5G base station communicates with the ground through the NG interface, and the NG interface mainly interacts with the NAS signaling of the core network and the service data of the user.

[0151] As shown in FIG. 3, which is an example diagram of an O-RAN system. The O-RAN system can include other components in addition to the components shown in FIG. 3. The network device also becomes an access network device. The access network device (RAN, which can be an eNB or a gNB or a next-generation access network device) communicates with the core network (CN) through a backhaul link and communicates with the user equipment (UE) through an air interface.

[0152] Specifically, a baseband unit (BBU) in an access network device communicates with a core network through a backhaul, and a radio unit (RU) in the access network device communicates with at least one UE through an air interface. The BBU communicates with at least one RU through a fronthaul, and the BBU and the RU can be co-located or not co-located.

[0153] The BBU includes at least one control unit (CU) and at least one distributed unit (DU), which can communicate through at least one midhaul.

[0154] As shown in FIG. 4, FIG. 4 is a diagram of network element function division and protocol layer structure of an open radio access network (ORAN) device.

[0155] In some examples, the CU is a logical node that carries a radio resource control (RRC) layer, a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU is connected to network nodes such as a 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) layer 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 control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is an application protocol for the F1 interface, which defines signaling procedures for F1 in some examples. The F1 interface supports a control plane F1-C and a user plane F1-U.

[0156] In some examples, the CU can be split into a control unit-control plane (CU-CP) and a control unit-user plane (CU-UP), where the CU-CP is a logical node carrying an RRC layer and a control plane part of a PDCP (PDCP-C) layer, used to implement control plane functions of the CU. The CU-CP can interact with a network element in the core network used to implement control plane functions. The network element in the core network used to implement control plane functions can be an access and mobility function network element, such as an access and mobility management function (AMF) in a 5G system. The AMF network element is used 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 an SDAP layer and a user plane part of a PDCP (PDCP-U) layer, used to implement user plane functions of the CU. The CU-UP can interact with a network element in the core network used to implement user plane functions. The network element in the core network used to implement user plane functions, for example, a user plane function (UPF) in a 5G system, is used 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 functions as needed. For example, the CU or the DU can be configured to have functions of more protocol layers, or the CU or the DU can be configured to have partial processing functions of protocol layers. For example, partial functions of an RLC layer and functions of protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of 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 a service type or other system requirements, for example, according to a delay requirement. Functions that need to meet a relatively low delay requirement in processing time are arranged in the DU, and functions that do not need to meet the delay requirement are arranged in the CU.

[0157] In some examples, a DU is a logical node that hosts radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU is connected with the RUs through some interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes parts of PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.

[0158] In some examples, an RU is a logical node that hosts lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, an RU can be a 3GPP transmission reception point (TRP) or a remote radio head (RRH) or other similar functional entity. In some examples, the Low-PHY includes parts of PHY processing, such as fast fourier transform (FFT), inverse fast fourier transformation (IFFT), digital beamforming and filtering, etc. An RU communicates with one or more UEs through wireless links.

[0159] The DU and the RU can be co-located or not co-located. The DU and the RU exchange control plane information and user plane information via a lower-layer split CUS-Plane (LLS-CUS) interface through a fronthaul link. The LLS-CUS can include a LLS-C interface and a LLS-U interface that provide control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via a LLS-M interface of the fronthaul link, and the management plane (M-Plane) refers to non-real-time management operations between the DU and the RU.

[0160] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected with one or more RUs. The functions of the DU and the RU can be configured in various ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or to implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of the functions of the PHY layer that are closer to the radio frequency side.

[0161] The CU (or CU-CP and CU-UP), the DU or the RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an 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.

[0162] Based on the above description of CSI, it can be known that the channel state information CSI is the channel attribute of the communication link. It describes the attenuation factors of the signal on each transmission path, i.e., the values of each element in the channel gain matrix H, such as signal scattering (Scattering), environmental attenuation (fading, multipath fading or shadowing fading), distance attenuation (power decay of distance) and the like. The channel state information CSI can enable the communication system to adapt to the current channel conditions and provide a guarantee for high-reliability high-rate communication in a multi-antenna system. Complete CSI is described through three dimensions: time, frequency and space, which correspond to the changes experienced by the wireless channel with respect to time, carrier frequency and spatial distribution, respectively. In actual application, the network device configures multiple measurement resources for the terminal device through radio resource control (RRC) signaling, and each measurement resource corresponds to a reference signal. For each measurement resource, the network device transmits the reference signal corresponding to the resource through a channel, and the terminal device measures the reference signals transmitted by each channel to determine the quality of the channel, such as the reference signal receiving power (RSRP). By measuring the RSRP of each channel, the terminal device selects one or more channels / resources with the maximum RSRP and reports the index of the channel and the corresponding RSRP to the network device.

[0163] A typical implementation process is introduced as follows. As shown in FIG. 5, FIG. 5 is a schematic diagram of measurement reporting. The network device is provided with M channels, and the terminal device is provided with N channels. The network device configures M reference signals for the terminal device, which correspond to M network device beams (channels) respectively. In each measurement period, the network device transmits the M reference signals through the M channels respectively, and the terminal device receives and measures the M reference signals. Through N measurement periods, the terminal device traverses all N channels of the terminal device, thereby completing channel measurement of all network device beams and all terminal device beams. Based on the above measurement, the terminal device can select the best K reference signals / channels, and report the resource indexes of the K reference signals and RSRP to the network device.

[0164] As shown in FIG. 6, FIG. 6 is a schematic diagram of three measurement reporting processes. The network device can configure three measurement reporting processes for the terminal device: a periodic measurement reporting process, a semi-persistent measurement reporting process and an aperiodic measurement reporting process.

[0165] Periodic measurement reporting: the measurement reporting process is periodically executed, that is, the network device periodically transmits measurement reference signals to the terminal device, and the terminal device measures the reference signals and reports the measurement results. The start of the process is RRC configuration, and once the RRC configuration takes effect, the process will be periodically executed. To terminate a certain measurement reporting process, it is necessary to resend the RRC configuration information to release the related configuration parameters of the measurement reporting process.

[0166] Semi-persistent measurement reporting: the measurement reporting process is periodically executed, that is, the network device periodically transmits measurement reference signals to the terminal device, and the terminal device measures the reference signals and reports the measurement results. The start of the process is not RRC configuration, but activation signaling. After the RRC configuration takes effect, the measurement reporting will not be executed. The network device needs to send an activation signaling to the terminal device to activate a specific semi-persistent measurement reporting process. Once activated, the measurement reporting process will be periodically executed. The network device can also send a deactivation signaling to the terminal device to deactivate a specific semi-persistent measurement reporting process.

[0167] Aperiodic measurement reporting: the measurement reporting process is executed aperiodically, and the network device only transmits measurement reference signals to the terminal device once, and the terminal device measures the reference signals and reports the measurement results. The start of the process is not RRC configuration, but trigger signaling. After the RRC configuration takes effect, the measurement reporting will not be executed. The network device needs to send a trigger signaling to the terminal device to trigger a specific aperiodic measurement reporting process. Each time a trigger information is received, a measurement reporting is performed.

[0168] However, the above three measurement reporting processes are dominated by the network device, that is, the network device decides when to issue the reference signal and the terminal device when to report the measurement result. However, in a large communication delay scenario, such as a satellite and ground communication scenario, such as a non-terrestrial network (NTN), the measurement reporting time determined by the network device may conflict with the transmission time of other downlink signals, resulting in failure of the terminal device to send the measurement report, or the network device issues the reference signal conflicting with the uplink signal of the terminal device, so that the terminal device cannot measure the corresponding reference signal. Please refer to FIG. 7, which is a schematic diagram of conflict alignment provided by an embodiment of the present application. In FIG. 7, the conflict situation of the terminal device and the conflict situation considered by the base station may be aligned. As shown in FIG. 7, the base station considers that UL7 conflicts, and the terminal device will cancel UL7, but actually UL8 conflicts and UL7 does not conflict. Then the base station may use UL to schedule data of other terminal devices, and the terminal device will send data because UL7 does not conflict, thereby causing interference with the data of other terminal devices at the base station side, resulting in the base station being unable to decode the data of the two terminal devices. It should be noted that the timing relationship considered by the base station is determined based on the timing advance (TA) reported by the terminal device. The so-called TA is the round-trip transmission delay, and the base station can calculate the transmission delay based on the TA. However, the TA reported has errors, and finally the conflict considered by the base station and the actual conflict of the terminal device do not match, resulting in the occurrence of the conflict situation. In addition, it should be noted that the uplink switching to downlink and the downlink switching to uplink actually have corresponding intervals. Here, in order to simplify the legend, this content is not shown.

[0169] For a half-duplex terminal device, since the uplink and downlink of the half-duplex terminal device cannot be performed at the same time, the measurement reporting of the terminal device may conflict with the uplink signal or the downlink signal. Regardless of which conflict situation occurs, it results in waste of resources pre-configured by the network device.

[0170] To solve the above technical problems, the embodiments of the present application provide the following solutions.

[0171] As shown in FIG. 8, which is a flowchart of a communication method provided by an embodiment of the present application. The embodiments of the present application mainly include the following steps:

[0172] Step S801: The network device sends a first reference signal to the terminal device.

[0173] In an alternative implementation, the network device sends configuration information of the reference signal to the terminal device before sending the first reference signal to the terminal device. The configuration information of the reference signal can include one or more of the following parameters: transmission power of the reference signal, time domain resource configuration of the reference signal, frequency domain resource configuration of the reference signal, and spatial domain resource configuration of the reference signal. The time domain resource configuration can include or be embodied as time domain resource density, the frequency domain resource configuration can include or be embodied as frequency domain resource density, and the spatial domain resource configuration can include one or more of the following parameters: port number or beam configuration; for example, the beam configuration can include precoding configuration. The precoding here can also be referred to as beamforming; for example, precoding (or beamforming) can mean that each antenna port is multiplied by a weight value when transmitting a signal; for example, for a 4-antenna port, the following weight values are multiplied respectively: 0.5, -0.5, 0.5, -0.5j, and j represents an imaginary number. It should be noted that the configuration information can also be the configuration information of the reference signal sent by the network device to the terminal device at the time when the network device reaches the expected time of sending the first reference signal.

[0174] In addition, the configuration information can also include resource type, which can be used to indicate the type of the first reference signal. The resource type can include periodic, semi-static, and aperiodic. It should be understood that other information in the configuration information in the embodiments of the present application can be referred to the prior art. It can be understood that the configuration information is used to represent the related signal of the first reference signal.

[0175] In an alternative implementation, the CSI resource configuration (resource setting) is as follows:

[0176] 1. M≥1 resource configurations (resource settings);

[0177] 2. One resource configuration contains S≥1 CSI-RS resource sets (resource sets);

[0178] 3. One resource set contains Ks≥1 RS resources (resources), such as CSI-RS / CSI interference measurement (CSI-IM) resources;

[0179] 4. One CSI-RS resource is used to configure the number of ports of the CSI-RS and the information of time and frequency positions, etc.; and one CSI-IM resource is used to configure the information of time and frequency positions of the CSI-IM, etc.

[0180] In an alternative implementation, the first reference signal can also be sent by a device other than the network device to the terminal device.

[0181] Step S802: The terminal device confirms that the first reference signal conflicts with other signals.

[0182] In the embodiments of the present application, the terminal device is a half-duplex terminal, and due to the characteristics of the half-duplex terminal, i.e., uplink and downlink cannot be performed at the same time. The uplink and downlink of such a terminal device need to be separated by N Tx-Rx , and the downlink and uplink need to be separated by N Rx-Tx , which can be respectively shown in Table 1 in low frequency band FR1 and high frequency band FR2, where the numbers represent the number of sampling points, and the specific interval is the number of sampling points multiplied by the sampling point interval:

[0183] Table 1

[0184] In the scenario where the first reference signal conflicts with other signals (uplink signals sent by the terminal), i.e., the first reference signal of the downlink conflicts with the uplink signals sent by the terminal, it is indicated that such a terminal device can not receive the first reference signal due to sending uplink signals with high priority at the same time.

[0185] Based on the above introduction of the reference signal, the terminal device generates a corresponding CSI measurement report by receiving and measuring the reference signal, but due to the conflict, the terminal device cannot receive the first reference information, and thus cannot measure the first reference signal.

[0186] Due to the occurrence time and measurement time of the first reference signal, which are pre-configured by the network device, the terminal device knows that the first reference signal conflicts with the uplink signal when sending the uplink signal with high priority. The method provided in the embodiments of the present application is also for such a case.

[0187] Step S803: The terminal device generates a CSI measurement report of the second reference signal through the first computing resource.

[0188] The terminal device measures the channel state based on the resource of the reference signal (such as the channel state information reference signal), and feeds back (reports) the channel state information CSI to the network (for example, a base station).

[0189] In an alternative embodiment, the first computing resource is a predetermined resource for generating the CSI measurement report of the first reference signal. Illustratively, the configuration information described above includes the first computing resource, i.e. the terminal device reserves the corresponding computing resource for generating the CSI measurement report at the preset time point of receiving / measuring the first reference signal by receiving the configuration information, so as to use the computing resource when generating the CSI measurement report. However, due to the conflict of the first reference signal, the terminal device cannot measure the first reference signal, and then if the terminal device still sends the CSI measurement report of the first reference signal at the preset time point, but the content of the report is no update, i.e. the terminal device can select the content of the CSI measurement report of the last period of the first reference signal as the content of the CSI measurement report of the current conflicting first reference signal. It can be understood that, since there is no need to update the content, the first computing resource of the terminal device is idle, which undoubtedly wastes the resource.

[0190] In the embodiments of the present application, the terminal device can generate the CSI measurement report of the second reference signal through the first computing resource, so as to avoid the waste of the resource. In some possible implementations, the first computing resource can be used to represent the processing capability of a terminal device, which is determined by the hardware of the terminal device, and does not need to be pre-configured by the network device.

[0191] Optionally, the terminal device further includes a second computing resource, which is a resource for generating the CSI measurement report of the second reference signal, and the second computing resource can be used for the CSI measurement report of other subsequent reference signals.

[0192] Optionally, since the measurement of the second reference signal has been completed according to the first computing resource, the second computing resource is not needed, and thus the terminal device can release the second computing resource.

[0193] In an alternative embodiment, the terminal device releases the first computing resource in advance when determining that the first reference signal conflicts, so as to avoid the waste of the resource.

[0194] In another alternative embodiment, considering that the use of the second computing resource can need to wait until the terminal device receives other reference signals, which means that the second computing resource can still exist idle time, the terminal device releases the second computing resource after generating the CSI measurement report of the second reference signal through the first computing resource.

[0195] In an alternative implementation, the CSI measurement report can include a signal to interference plus noise ratio (SINR), a reference signal receiving power (RSRP), a reference signal receiving quality (RSRQ), a relative time of arrival (RTOA), or an angle of arrival (AOA). Alternatively, the CSI measurement report can also be a quantization result of the above multiple measurements.

[0196] Exemplarily, the CSI measurement report content can include:

[0197] The terminal can be configured with a CSI-ReportConfig, with the higher layer parameter reportQuantity set to 'none', 'cri-ri-pmi-cqi', 'cri-RI-i1', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR','ssb-Index-RSRP','ssb-Index-SINR', or 'cri-RI-LI-PMI-CQI'.

[0198] If the terminal is configured with a CSI-ReportConfig, and the higher layer parameter reportQuantity is set to 'none', the terminal will not report any content for the CSI-ReportConfig.

[0199] If the terminal is configured with a CSI-ReportConfig, and the higher layer parameter reportQuantity is set to 'cri-RI-PMI-CQI' or 'cri-RI-LI-PMI-CQI', the terminal shall report one precoding matrix for the entire reporting band, or one precoding matrix for each sub-band.

[0200] If the terminal is configured with a CSI-ReportConfig, and the higher layer parameter reportQuantity is set to 'cri-RI-i1-CQI', the UE shall report one PMI, including a single wideband indication for the entire CSI reporting band.

[0201] In addition, the CSI measurement report can also include at least one of a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), an SS / PBCH block resource indicator (SSBRI), a layer indicator (LI), a rank indicator (RI), a layer 1 reference signal received power (L1-RSRP), a reference signal received quality (L1-RSRQ), a signal to interference plus noise ratio (L1-SINR), a layer 1 signal to noise ratio (L1-SNR), and the like.

[0202] It should be noted that the priorities of the CSI measurement reports of different reference signals are generally different. In general, the higher the priority of the CSI measurement report, the more important the measured channel or the higher the quality of the corresponding channel. Therefore, the CSI measurement report of a reference signal with a lower priority is generally discarded when resource multiplexing is performed. In an optional embodiment, the priority of the CSI measurement report of the first reference signal is higher than the priority of the CSI measurement report of the second reference signal. This means that although the priority of the CSI measurement report of the second reference signal is lower than that of the first reference signal, the CSI measurement report of the second reference signal with a relatively lower priority is still considered when resource multiplexing is performed. Optionally, the terminal device needs to perform measurement on multiple reference signals, including a first reference signal and a second reference signal. The priority of the CSI measurement report corresponding to the first reference signal is higher than the priority of the CSI measurement report corresponding to other reference signals in the multiple reference signals. The priority of the measurement report of the second reference signal is lower than the priority of the measurement report of the first reference signal, but is still higher than the priority of the measurement report of the other reference signals except the first reference signal.

[0203] In order to make full use of the terminal's ability to update the CSI measurement report that can be updated, in an alternative embodiment, the terminal device determines the reporting queue according to the conflict of the reference signals, for example, the reference signals and the uplink signals with high priority generate conflict. The reporting queue is used for the reporting of the CSI measurement report, that is, the terminal device can report the CSI measurement report of each reference signal according to the order and content of the CSI measurement report in the reporting queue.

[0204] In another alternative embodiment, the terminal device generates other CSI measurement reports in the reporting queue according to the processing capacity and the reporting queue. The processing capacity is used to represent the processing capacity of the CPU of the terminal device in this embodiment. For example, assuming that the terminal device has 2 CSI measurement reports with high priority in the conflict state (that is, the corresponding reference signals conflict with the uplink signals sent by the terminal device), the ability of the terminal device is to report N CSI measurement reports, and there are M CSI measurement reports in total. Then the terminal device puts the N CSI measurement reports without conflict and with high priority in the front row of the reporting queue, which means that the N CSI measurement reports without conflict and with high priority will be reported first, even if there is a CSI measurement report with higher priority than the N CSI measurement reports without conflict, but the CSI measurement report is in conflict, and the CSI measurement report will be placed in the back row of the reporting queue, that is, the CSI measurement report will be placed after the first N CSI measurement reports in the reporting queue. For details, please refer to FIG. 9, which is a schematic diagram of the terminal device processing the conflict CSI measurement report according to the CPU capacity provided by the embodiment of the present application. In FIG. 9, there are 10 CSI measurement reports in total, which are denoted as CSI0, CSI1, CSI2, CSI3, CSI4, CSI5, CSI6, CSI7, CSI8, CSI9, and CSI10. The above CSI measurement reports are arranged according to the priority, for example, the priority of CSI0 is higher than that of other CSI reports. As shown in FIG. 9, the CPU capacity covers 5, in the case of no conflict, the CSI measurement reports covered by the CPU include CSI0, CSI1, CSI2, CSI3, and CSI. But in the case of determining that CSI1 is in conflict, the terminal device adjusts the update order of the above CSI measurement reports according to the CPU capacity. As shown in the figure, the conflict CSI1 is marked in gray, which means that the current batch of CPU does not update CSI1, but delays the update of the original CSI5 that is not covered by the ability. In FIG. 9, gray represents no update, and black represents update.

[0205] The processing capacity of the terminal device is described below.

[0206] Specifically, the terminal device indicates the number of CSI calculations that can be supported on each carrier and all carriers, i.e., Ncpu. If a terminal device supports Ncpu CSI calculations at the same time, it means that it has Ncpu CSI processing units to process CSI reports. If there are L CPUs occupied to calculate CSI reports on an orthogonal frequency division multiplexing (OFDM) symbol, the terminal device has Ncpu-L CPUs that are not occupied. If N CSI reports occupy the corresponding CPUs on an OFDM symbol, Ncpu-L CPUs are not occupied. Where CSI report n=0,…,N-1 corresponds to Ocpu(n), the terminal device does not need to update N-M CSI reports with low configuration priority. The value of M is the maximum value that satisfies 0<=M<=N.

[0207] In an alternative implementation, the priority of the CSI measurement report can be implemented based on the following.

[0208] In Rel.15 / 16 NR, a CSI report (which can also be referred to as a CSI report, CSI feedback, etc.) can also be associated with a priority value. For example, the priority value can also be defined using the function PriiCSI(y, k, c, s). The priority can also be mutually replaced with CSI report priority, CSI priority, etc.

[0209] Here, y can be a value based on the type of CSI report (A-CSI report or SP-CSI report or P-CSI report) and the channel PUCCH or uplink control channel PUCCH that transmits the CSI report.

[0210] For example, it can also be that if it is an A-CSI report transmitted by PUSCH, y=0, if it is an SP-CSI report transmitted by PUSCH, y=1, if it is an SP-CSI report transmitted by PUCCH, y=2, and if it is a P-CSI report transmitted by PUCCH, y=3.

[0211] k can also be a value based on whether the CSI report contains L1-RSRP / SINR (for example, k=0 if the CSI report contains L1-RSRP / SINR, and k=1 if it does not). c can also be a serving cell index. s can also be a report configuration ID (reportConfigID).

[0212] ​For example, PriiCSI(y, k, c, s) can also be calculated by the following formula (1).

[0213] PriiCSI(y, k, c, s) = 2 Ncells Ms y + Ncells Ms k + Ms c + s (1)

[0214] Here, Ncells can also be a value of the maximum number of serving cells set (higher layer parameter maxNrofServingCells), and Ms can be a value of the maximum number of CSI report configurations set (higher layer parameter maxNrofCSI-ReportConfigurations).

[0215] In the case where the value of PriiCSI(y, k, c, s) associated with the first CSI report is less than the value of PriiCSI(y, k, c, s) associated with the second CSI report, it can also mean that the first CSI report has a higher priority than the second CSI report.

[0216] In another optional implementation, the reporting queue is used for generation of CSI measurement reports, and the terminal device arranges the generation time and generation resource of the CSI measurement report corresponding to each reference signal according to the conflict situation of the reference signals, to obtain the reporting queue. The terminal device generates the CSI measurement report of each reference signal at the corresponding time point according to the order of the reporting queue.

[0217] Since there is a case of changing the preset reporting order of the CSI measurement report in the above-mentioned multiple implementations, there is a difference from the pre-configuration of the network device. In order to solve this problem, in an optional implementation, each CSI measurement report has an index value (identity, ID), referred to as CSIreportID or index ID. The index ID is used to make the network device know that the terminal side has modified the reporting order of the CSI measurement report, which helps the network side to quickly locate and process the required CSI measurement report, and improves the data processing efficiency.

[0218] Step S804: The terminal device sends the CSI measurement report of the second reference signal to the network device through the first time-frequency resource.

[0219] The first time-frequency resource can be a periodic PUCCH resource or a configured grant (CG) PUSCH resource.

[0220] Optionally, the configuration information can further include a second time-frequency resource. The terminal device sends an uplink transmission resource request to the network device through the second time-frequency resource, and the uplink transmission resource request is used to request the network device to schedule an uplink resource to report the CSI measurement report. In this case, the resource for sending the CSI measurement report is scheduled by the network device after receiving the uplink transmission resource request, rather than being sent through the first time-frequency resource. And / or, the terminal device sends a notification message to the network device through the second time-frequency resource, and the notification message is used to notify the network device that the CSI measurement report will be sent to the network device.

[0221] The second time-frequency resource can be a resource specially used for the CSI measurement report reporting process initiated by the terminal device. For example, the second time-frequency resource is a scheduling request (SR) resource. The configuration of the second time-frequency resource can be achieved by configuring the index of the SR. The information of the second time-frequency resource can be configured in the reporting configuration, which is used to indicate that the reporting of the CSI measurement report corresponding to the reporting configuration is requested or notified through the second time-frequency resource.

[0222] Optionally, the terminal device can send capability information to the network device, and the capability information is used to indicate the capability of the terminal device to initiate the measurement result reporting.

[0223] The capability information can include one or more of the following: whether the terminal device supports the measurement reporting process initiated by the terminal device; the number of measurement reporting processes (the number of reporting configurations, one reporting configuration corresponds to one measurement reporting process) that the terminal device can request in the measurement reporting process initiated by the terminal device; the number of trigger states that the terminal device can request, each trigger state binds one or more reporting configurations; and the number of reference signals that the terminal device can measure in the measurement reporting process initiated by the terminal device.

[0224] For example, the terminal device can send the capability information to the network device before the network device sends the measurement configuration information to the terminal device. If the network device determines that the terminal device supports initiating the measurement result reporting according to the capability information, the network device sends the terminal device the conditions or events for initiating the measurement result reporting. If the network device determines that the terminal device does not support initiating the measurement result reporting, the network device does not send the terminal device the conditions or events for initiating the measurement result reporting. If the terminal device receives the conditions or events for initiating the measurement result reporting, the terminal device sends the CSI measurement report accordingly. If the terminal device does not receive the conditions or events for initiating the measurement result reporting, the terminal device sends the CSI measurement report.

[0225] The conflict mainly involved in the above content of the embodiments of the present application is the conflict between the reference signal and the uplink signal, in addition to which, there can be a conflict between the CSI measurement report and at least one downlink signal from the network device, i.e., a conflict between the uplink measurement report and the downlink signal.

[0226] To solve the conflict between the CSI measurement report and at least one downlink signal from the network device, in an optional implementation, please refer to FIG. 10, which is a schematic diagram of adjusting the priority of the CSI measurement report provided by the embodiments of the present application. Specifically, the terminal device determines a reporting queue of the CSI measurement report, the reporting queue being obtained by sorting in the order from high to low of the priority of the CSI measurement report; the reporting queue including a first CSI measurement report and a second CSI measurement report, the priority of the first CSI measurement report being higher than the priority of the second CSI measurement report; when the first CSI measurement report in the reporting queue conflicts with at least one downlink signal from the network device, the reporting queue is updated to obtain an updated reporting queue, the priority of the first CSI measurement report in the updated reporting queue being lower than the priority of the second CSI measurement report. This means that if the CSI measurement report conflicts, the priority of the CSI measurement report (the first CSI measurement report) will be adjusted to be lower, and the CSI measurement report (the second CSI measurement report) without conflict will be reported preferentially. It can be understood that the CSI measurement report with the adjusted priority will also be adjusted accordingly.

[0227] Correspondingly, the above-mentioned conflict refers to the conflict between the first CSI measurement report and at least one downlink signal from the network device, in addition to which, if the reference signal corresponding to the first CSI measurement report conflicts with at least one uplink signal sent by the terminal, the reporting queue is updated to obtain an updated reporting queue, the priority of the first CSI measurement report in the updated reporting queue being lower than the priority of the second CSI measurement report.

[0228] In FIG. 10, after the priority of the first CSI measurement report in conflict is adjusted to the priority of the second CSI measurement report without conflict, the conflict is avoided. In actual application, the transmission time-frequency of the CSI measurement report of the second reference signal is close to the transmission time-frequency of the CSI measurement report of the first reference signal. In this case, the reporting order is correspondingly postponed, and the other CSI measurement report with priority lower than the first reference signal and the second reference signal is adjusted to the first order to avoid the conflict. It can be understood that the priority of the CSI measurement report of the first reference signal is adjusted to avoid the conflict in transmission time-frequency. Therefore, in actual application, the priority of the CSI measurement report of the first reference signal can be adjusted to any position in the reporting queue, which is not limited in the present application.

[0229] It should be understood that, in the embodiments of the present application, the "reporting conflict of two information" can be understood as "conflict of two resources corresponding to two information respectively carried on the two resources". The resource configured to carry certain information can be understood as the resource for carrying certain information. When the resource does not conflict with other resources, the certain information can be transmitted on the resource; when the resource conflicts with other resources, the certain information can be transmitted on the resource, can not be transmitted on the resource, or can be transmitted on the resource together with other information. The specific information transmitted on the resource or no information transmitted on the resource is determined according to the priority and resource multiplexing rules in the present application.

[0230] In an optional embodiment, if the CSI measurement report of the reference signal with lower priority (for example, the CSI measurement report of the second reference signal) determines that there is a conflict, the priority of the CSI measurement report is also adjusted accordingly to avoid the conflict.

[0231] In an optional embodiment, considering that the CSI measurement report of the first reference signal has no update, the network device cannot perceive the current state of the channel by receiving the CSI measurement report, and therefore the CSI measurement report of the first reference signal is deleted from the reporting queue; correspondingly, the CSI measurement report of the second reference signal in the first position of the reporting queue is transmitted through the first time-frequency resource configured for the first reference signal by default. It can be understood that, when the CSI measurement report of the first reference signal is not deleted from the reporting queue, the first position of the reporting queue is the CSI measurement report of the first reference signal.

[0232] Step S805: The network device receives the CSI measurement report of the second reference signal on the first time-frequency resource.

[0233] In the embodiments of the present application, in order to cope with the conflict situation in different situations, the terminal device can reduce the resource waste caused by the conflict by applying the idle computing resources to the generation of the CSI measurement report of the other reference signal. The terminal device can also avoid the conflict by adjusting the sending order or the sending time-frequency of the CSI measurement report that conflicts with the uplink signal.

[0234] In an optional implementation, in addition to the conflict between signals, there can also be a conflict between channels. In the existing standard protocol, for the same priority PUSCH conflict, the existing standard processing rule is to determine the abandoned PUSCH according to the CSI priority carried by the PUSCH. It can be understood that the PUSCH carrying a lower CSI priority is abandoned. First of all, it should be clarified that the CSI feedback is carried on the PUSCH, and one PUSCH transmission can include one or more CSI feedbacks. The CSI feedback has a corresponding priority, and the embodiments described above are all for the conflict between multiple CSI feedbacks in the same PUSCH.

[0235] The present embodiment is mainly used to solve the problem of PUSCH conflict in the scenario where there are multiple PUSCHs, and these PUSCHs can all carry CSI feedback.

[0236] As shown in FIG. 11, FIG. 11 is a flow diagram of another communication method provided by the embodiments of the present application. The embodiments of the present application mainly include the following steps:

[0237] Step S1101: The network device sends a third reference signal and a fourth reference signal to the terminal device.

[0238] The sending time of the third reference signal and the fourth reference signal is the same, or is relatively close, or the sending time of the two is completely separated, which is not limited in the present application.

[0239] Step S1102: The terminal device receives the third reference signal or the fourth reference signal.

[0240] Specifically, the third reference signal or the fourth reference signal conflicts with the uplink signal, so that the terminal device cannot receive and measure the conflicting reference signal.

[0241] Step S1103: The terminal device determines that the physical uplink data channel (PUSCH) of the third CSI measurement report conflicts with the PUSCH of the fourth CSI measurement report.

[0242] It should be understood that, in the embodiments of the present application, the "collision of two channels" can be understood as "collision between two resources". It can be understood that there can be overlap or partial overlap between resources, or it can be considered that there is a possibility of overlap. The above-mentioned proximity includes that the difference between the resources is within a preset range, and the preset range is a smaller value defined in advance according to requirements.

[0243] Step S1104: The terminal device sends the first content to the network device through the PUSCH.

[0244] In the embodiments of the present application, the PUSCH carrying the third CSI measurement report collides with the PUSCH carrying the fourth CSI measurement report, which represents that the two PUSCHs are the same PUSCH, and the PUSCH for sending the first content in step S804 is the PUSCH. In actual application, the collision of the PUSCH carrying the third CSI measurement report and the PUSCH carrying the fourth CSI measurement report only represents that there is partial overlap between the two channels, or even only close, and in this case, the PUSCH for sending the first content in step S804 is the PUSCH with earlier timing.

[0245] Optionally, the first content includes the CSI measurement report corresponding to the reference signal without collision in the third CSI measurement report and the fourth CSI measurement report, or the first content includes the third CSI measurement report and the fourth CSI measurement report.

[0246] It should be noted that the first content includes two cases, and the two cases represent two conflict resolution schemes respectively, and the two cases will be described below.

[0247] Case one, the first content includes the CSI measurement report corresponding to the reference signal without collision in the third CSI measurement report and the fourth CSI measurement report.

[0248] In case one, the terminal device determines the sending content according to the conflict situation of the CSI measurement reports carried in the PUSCH. Specifically, the third CSI measurement report and the fourth CSI measurement report have a conflict situation corresponding to the reference signals. For example, the priority of the third CSI measurement report is higher than the priority of the fourth CSI measurement report. According to the existing protocol standard, the terminal device should send the third CSI measurement report with higher priority. However, since the terminal device determines that the reference signal (the third reference signal) corresponding to the third CSI measurement report has a conflict, the third CSI measurement report is not updated. Therefore, the terminal device does not send the third CSI measurement report, but selects to send the fourth CSI measurement report with lower priority, thereby solving the problem that the terminal device discards the PUSCH carrying the CSI corresponding to the CSI measurement report (the CSI measurement report without update) with lower priority due to the conflict of the PUSCH sending, and the network side cannot receive the updated CSI measurement report.

[0249] In case two, the first content includes the third CSI measurement report and the fourth CSI measurement report.

[0250] In case two, if two PUSCHs conflict and both of them carry CSI measurement reports, the terminal device can combine the contents in the two PUSCHs to report, thereby solving the conflict problem of the PUSCH. Optionally, the starting point of the first content is determined according to the starting point of the PUSCH with relatively earlier timing / the starting point of the CSI measurement report in the PUSCH with relatively earlier timing.

[0251] It should be noted that in case two, whether the CSI measurement reports in the PUSCH have a conflict or not, the CSI measurement reports in the two PUSCHs can still be combined to obtain the first content. For example, the first content includes the third CSI measurement report and the fourth CSI measurement report, and the third CSI measurement report and the fourth CSI measurement report do not have a conflict corresponding to the reference signals.

[0252] In an optional implementation, whether it is case one or case two, it involves applying a change to the pre-configured time-frequency resource. Therefore, the first content includes an index ID, and the index ID is used to represent the ID of the CSI measurement report included in the first content. For example, if the first content includes the CSI measurement report corresponding to the reference signal without a conflict in the third CSI measurement report and the fourth CSI measurement report, and the reference signal corresponding to the third CSI measurement report has a conflict, it means that the first content includes the fourth CSI measurement report. Correspondingly, the first content also includes the index ID of the fourth CSI measurement report.

[0253] Step S1105: The network device receives the first content sent by the terminal device.

[0254] The first content includes a CSI measurement report corresponding to a reference signal without conflict in the third CSI measurement report and the fourth CSI measurement report, or the first content includes the third CSI measurement report and the fourth CSI measurement report. The third CSI measurement report is sent by the terminal according to the third reference signal, and the fourth CSI measurement report is sent by the terminal according to the fourth reference signal.

[0255] In an optional implementation, the above content mainly shows the case of two PUSCH conflicts, and in addition, the cases of three, four, or even more PUSCH conflicts can still use the method shown in FIG. 11, which only needs to be adaptively adjusted.

[0256] In the embodiments of the present application, in the face of the conflict problem of PUSCHs with the same priority, the terminal device can determine the sending content according to the conflict situation of the CSI measurement report carried in the PUSCH, avoid sending no updated measurement report to the network device, and make the network side receive the updated CSI feedback as much as possible. The content in the conflicting PUSCHs can also be combined, thereby reducing the information loss of the CSI feedback.

[0257] It can be understood that the methods and operations implemented by the terminal device in each of the above method embodiments can also be implemented by components (such as chips or circuits) that can be used for the terminal device, and the methods and operations implemented by the network device can also be implemented by components (such as chips or circuits) that can be used for the network device.

[0258] The embodiments of the present application can divide the functional modules of the terminal device or the network device according to the above method examples, for example, each functional module can be divided according to each function, or two or more functions can be integrated in one processing module. The above integrated module can be implemented in the form of hardware or in the form of a software functional module. It should be noted that the division of the modules in the embodiments of the present application is illustrative, and is only a logical function division. In actual implementation, another division mode can be used. The following will be described taking the division of each functional module corresponding to each function as an example.
