[0002] The standard protocols developed by the 3rd generation partnership project (3GPP) have conducted relevant research on channel state information (CSI).

[0033] It should be noted that the "connection" mentioned in the embodiments of the present application refers to various connection methods such as direct connection or indirect connection to achieve communication between devices, and no specific limitation is imposed thereon.

[0035] It should be noted that the number of connections supported by traditional wireless communication systems is limited and they are easy to implement. However, with the development of communication technologies, wireless communication systems can not only support traditional wireless communication systems, but also support, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine type communication (MTC), vehicle-to-vehicle (V2V) communication, vehicle-to-everything (V2X) communication, narrow band internet of things (NB-IoT) communication, etc. Therefore, the technical solutions of the embodiments of the present application can also be applied to the above-mentioned wireless communication systems.

[0037] Optionally, the wireless communication system of the embodiments of the present application can be applied to unlicensed spectrum. Among them, unlicensed spectrum can also be considered as shared spectrum. Or, the wireless communication system in this embodiment can also be applied to licensed spectrum. Among them, licensed spectrum can also be considered as non-shared spectrum.

[0038] Since the embodiments of the present application describe each embodiment in combination with a terminal and a network device, the terminals, relay devices, and network devices involved will be specifically described below.

[0039] Specifically, the terminal can be a user equipment (UE), a remote UE, a relay UE, an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile device, a remote station, a mobile device, a user terminal, a smart terminal, a wireless communication device, a user agent, or a user device. It should be noted that a relay UE is a terminal that can provide relay forwarding services for other terminals (including remote UEs). Additionally, the terminal can 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 capabilities, a computing device, or other processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a next-generation communication system (such as an NR communication system, a 6G communication system), or a terminal in a future evolved public land mobile network (PLMN), etc., without specific limitations in this regard.

[0040] Furthermore, the terminal can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can be deployed on water (such as on a ship, etc.); it can also be deployed in the air (such as on an airplane, a balloon, and a satellite, etc.).

[0041] Furthermore, the terminal can be a mobile phone, a tablet (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in unmanned autonomous driving, a wireless terminal device in remote medical, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0042] Specifically, a network device can be a device used for communication with terminals, responsible for radio resource management on the air interface side, quality of service (QoS) management, data compression and encryption, data transmission and reception, etc. Among them, the network device can be a base station (BS) in a communication system or a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, a base transceiver station (BTS) in a GSM or CDMA communication system, a Node B (NB) in a WCDMA communication system, an evolved Node B (eNB or eNodeB) in an LTE communication system, a next generation evolved Node B (ng-eNB) in an NR communication system, a next generation Node B (gNB) in an NR communication system. In addition, the network device can be other devices in the core network (CN), such as an access and mobility management function (AMF), a user plan function (UPF), etc.; it can also be an access point (AP) in a wireless local area network (WLAN), a relay station, a communication device in a future evolved PLMN network, or a communication device in an NTN network, etc.

[0043] It should be noted that in some network deployments, the network device can be an independent node to implement all the functions of the above-mentioned base station. It can include a centralized unit (CU) and a distributed unit (DU), such as gNB-CU and gNB-DU, and can also include an active antenna unit (AAU). Among them, the CU can implement some functions of the network device, and the DU can implement some functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services and implementing the functions of the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, and packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services and implementing the functions of the radio link control (RLC) layer, medium access control (MAC) layer, and physical (PHY) layer. In addition, the AAU implements some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since the information in the RRC layer will ultimately become the information in the PHY layer, or is transformed from the information in the PHY layer, therefore, in this network deployment, high-layer signaling (such as RRC layer signaling) can be considered to be sent by the DU, or sent by the DU and the AAU. It can be understood that the network device can include at least one of the CU, DU, and AAU. In addition, the CU can be classified as a network device in the radio access network (RAN), or the CU can be classified as a network device in the core network, and no specific limitation is made in this regard.

Optionally, the network device can be a satellite or a balloon station. For example, the satellite can be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device can also be a base station set at locations such as land and water areas.

[0045] Further, the network device can provide services for a cell, and the terminals within the cell can communicate with the network device through transmission resources (such as spectrum resources). Among them, the cell can include a macro cell, a small cell, a metro cell, a micro cell, a pico cell, a femto cell, etc.

The wireless communication system 10 may include a network device 110 and terminals 120, and the network device 110 may be a device that communicates with the terminals 120. At the same time, the network device 110 can provide communication coverage for a specific geographical area and can communicate with the terminals 120 located within the coverage area.

[0047] Optionally, the wireless communication system 10 may further include multiple network devices, and a certain number of terminals may be included within the coverage range of each network device, which is not specifically limited herein.

[0048] Optionally, the wireless communication system 10 may further include other network entities such as a network controller and a mobility management entity, which is not specifically limited herein.

[0049] Optionally, the communication between the network device and the terminals in the wireless communication system 10, as well as the communication between terminals, can be wireless communication or wired communication, which is not specifically limited herein.

[0050] Before introducing in detail the method for aperiodic channel state information reporting provided by the embodiments of the present application, the related content involved in the embodiments of the present application will be introduced again.

[0051] 1. Channel State Information (CSI)

[0052] The protocol standards developed by the 3rd generation partnership project (3GPP) conduct relevant research on CSI. CSI is the channel state information used by the terminal to feedback the downlink channel quality to the network device, so that the network device can select a suitable modulation and coding scheme (MCS) for the transmission of downlink data, reduce the block error rate (BLER) of downlink data transmission, and perform corresponding beam management, mobility management, adaptation tracking, rate matching, etc. Among them, CSI includes channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-reference signal resource indicator (CRI), SS / PBCH block resource indicator (SSBRI), layer indicator (LI), rank indicator (RI), layer 1 reference signal received power (L1-RSRP), etc., and the time-frequency domain resources required for CSI transmission are configured by the network device. In addition, the relevant configuration information for CSI can be defined by the high-level parameter CSI-MeasConfig. Among them, CSI-MeasConfig defines parameters such as CSI-ResourceConfig and CSI-ReportConfig. CSI-ResourceConfig can be used to configure the CSI-RS resources for CSI measurement; CSI-ReportConfig can be used to configure how CSI is reported (i.e., the configuration information of the CSI report).

[0053] First, CSI-ResourceConfig can configure the ResourceSet, and the ResourceSet can contain the most basic CSI-RS resources (CSI-RS-Resource). CSI-RS-Resource can include three types: nzp-CSI-RS resources, SSB, and CSI interference management (CSI-IM) resources. Among them, the type of CSI-RS resources can be periodic, semi-persistent, or aperiodic.

[0054] Secondly, resourcesForChannelMeasurement, csi-IM-ResourcesForInterference, and nzp-CSI-RS-ResourcesForInterference in CSI-ReportConfig can represent csi-ResourceConfigId for channel measurement and interference measurement, and there is an association between csi-ResourceConfigId and csi-ResourceConfig, so as to obtain CSI-RS resources for CSI measurement.

[0055] Finally, reportConfigType in CSI-ReportConfig can be used to configure the type of CSI report. Among them, CSI can be reported through the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH). The types of CSI reports can be divided into: periodic (PUCCH reports CSI), aperiodic (PUSCH reports CSI), semi-persistent on PUCCH, and semi-persistent on PUSCH. For aperiodic CSI reports and semi-persistent CSI reports on PUSCH, the network side also configures TriggerState and reportTriggerSize to cooperate with the CSIrequest field in DCI.

[0056] 2. CSI report

[0057] Periodic CSI: After configuring periodic CSI-RS Resource and Report parameters through RRC, it will take effect immediately without activating or triggering CSI-RS transmission and CSI report through MAC-CE / DCI.

[0058] Semi-persistent CSI report on PUCCH: If semi-persistent CSI-RS transmission is configured through RRC, it is necessary to first activate CSI-RS transmission through MAC CE1 and then activate CSI report through MAC CE2; if periodic CSI-RS transmission is configured through RRC, it is not necessary to activate CSI-RS transmission through MAC CE1, but only need to activate CSI report through MAC CE2.

[0059] Uplink semi-persistent CSI reporting: If semi-persistent CSI-RS transmission is configured via RRC, CSI-RS transmission needs to be activated first via MAC CE1, and then CSI reporting is triggered via DCI; if periodic CSI-RS transmission is configured via RRC, CSI-RS transmission does not need to be activated via MAC CE1, but only CSI reporting is triggered via DCI. It should be noted that for DCI, the DCI can be DCI format 0_1 scrambled with SP-CSI-RNTI (semi-persistent CSI RNTI), and the CSI request field in the DCI can be associated with the corresponding trigger state (TriggerState) through the setting of the codepoint. The TriggerState defines the associated CSI-ReportConfig, so that the CSI-ReportConfig (CSI reporting configuration information) associated with the uplink semi-persistent CSI reporting can be found through the TriggerState.

[0060] Aperiodic CSI reporting: For the scenarios of aperiodic CSI-RS transmission and aperiodic CS reporting, both aperiodic CSI-RS transmission and aperiodic CSI reporting are triggered by DCI, and the process is similar to the above semi-persistent CSI reporting. When associating the corresponding TriggerState through the codepoint of the CSI request field in DCI format 0_1 / 0_2, different from the DCI trigger in the above semi-persistent CSI reporting, if the value of the CSI request field is 000, it means that triggering of the semi-periodic CSI reporting is not required; if the value of the CSI request field is 001, it means that the aperiodic CSI reporting associated with TriggerState 1 is triggered, and so on. After associating the TriggerState, the terminal can obtain two important parameters: CSI-ReportConfig and resourceSet. Among them, NZP-CSI-RS-ResourceSet in resourceSet is used for channel measurement.

[0061] 3. Quasi Co-Location (QCL)

[0062] To ensure the correct reception and demodulation of signals, the standard protocol introduces the concept of reference signals with a Quasi-Co-Location (QCL) relationship, such as CSI-RS, so that the terminal can estimate large-scale characteristic parameters based on CSI-RS. Among them, the large-scale characteristic parameters include at least one of delay spread, Doppler spread, Doppler frequency shift, average gain, average delay, spatial domain information, etc. For example, in R11 of the LTE communication system, the standard protocol introduces antenna port QCL. Antenna port QCL can indicate that the signals sent from the antenna port will undergo the same large-scale fading, thus having the same large-scale characteristic parameters. For example, when the QCL relationship is satisfied between antenna port A and antenna port B, the large-scale characteristic parameters estimated from the signals on antenna port A are also applicable to the signals on antenna port B.

[0063] In addition, in the NR communication system, the terminal and the network device may configure a large-scale array structure of multiple antenna panels, and the large-scale characteristics of the beams formed by different antenna panels will also be different. At this time, the large-scale characteristic parameters include, in addition to the delay spread, Doppler spread, Doppler frequency shift, average gain, and average delay described above, the angle of arrival (AOA), angle of arrival spread (AAS), angle of departure (AOD), angle of departure spread (ADS), and spatial correlation, etc.

[0064] 4. Antenna Port Quasi-Co-Location

[0065] In the high-layer parameter PDSCH-Config, up to M transmission configuration indication states (TCI states) can be configured for the terminal to decode the PDSCH according to the DCI detected in the PDCCH, where M depends on the terminal capabilities. Each TCI state contains parameters for configuring the quasi-co-location (QCL) relationship between one or two downlink reference signals (such as CSI-RS and / or SSB) and the demodulation reference symbol (DM-RS) port of the PDSCH, the DM-RS port of the PDCCH, or the CSI-RS port of the CSI-RS resource. The QCL relationship can be configured by the high-layer parameter qcl-Type1 for the first downlink reference signal and qcl-Type2 for the second downlink reference signal (if the second downlink reference signal is configured). For the case of two downlink reference signals, regardless of whether they are the same type of reference signal, the QCL types associated with the two downlink reference signals should not be the same. Among them, the QCL type associated with each downlink reference signal is determined by the high-layer parameter qcl-Type in QCL-Info and can take one of the following values:

[0066] QCL type A (QCL-TypeA): {Doppler frequency shift, Doppler spread, average delay, delay spread};

[0067] QCL type B (QCL-TypeB): {Doppler frequency shift, Doppler spread};

[0068] QCL type C (QCL-TypeC): {Doppler frequency shift, average delay};

[0069] QCL type D (QCL-TypeD): {Spatial reception parameters}.

[0070] Among them, the spatial reception parameters can include at least one of the following: AOA, average AOA, AOA spread, AOD, average AOD, AOD spread, receive antenna spatial correlation, transmit antenna spatial correlation, transmit beam, receive beam, resource identifier, etc. In addition, when the QCL type is QCL-TypeD, the TCI state can be used to indicate the beam. At the same time, each TCI state can give (contain) 1 or 2 QCL type parameters. If the TCI state contains 2 QCL type parameters, the QCL type will include the QCL-TypeD reference signal. That is, the QCL-TypeD reference signal will be configured in the TCI state.

[0071] Secondly, the TCI state can be activated by an activation command sent by the network side (such as a MAC control element CE) and indicated by the TCI field in the DCI. For example, when the TCI state is used for the QCL type indication of the PDSCH, the network device can first activate 2 N activated TCI states through the MAC CE, and then indicate one TCI state from these 2 N activated TCI states through the N-bit TCI field in the DCI. When N = 3, if the value of the TCI field in the DCI is '000', then this TCI indicates the first TCI state activated by the MAC CE. Additionally, with respect to the QCL type parameters given by this TCI state, the reference signal of this TCI state and the DM-RS port of the PDSCH are QCL.

[0072] In summary, for the triggering problem of aperiodic CSI reports, since there is a part of the DCI (such as DCI format 0_1 / 0_2) that carries a CSI request field, the terminal can learn whether there is an aperiodic CSI report and which aperiodic CSI reports are triggered through the CSI request field in this part of the DCI. For example, when the bit width of the CSI request field in DCI format 0_1 / 0_2 is 3 bits, if the value of this CSI request field is "000", it means that no aperiodic CSI report is triggered; if the value of this CSI request field is 001, it means that the aperiodic CSI report associated with TriggerState 1 associated with this CSI request field is triggered.

[0073] However, in the NR R17 phase, since there is another part of the DCI (such as DCI format 1_1 / 1_2) that may not contain (not carry) a CSI request field, this other part of the DCI cannot implement the triggering of aperiodic CSI reports. It can be seen that for the triggering problem of aperiodic CSI reports, further research is still needed.

[0074] Combined with the above description, the embodiment of the present application provides a flowchart of a method for aperiodic channel state information reporting. Please refer to Figure 2 The method includes the following steps:

[0075] S210. The network device sends the first downlink control information DCI to the terminal.

[0076] Among them, the first DCI can be used to determine the triggering state of the aperiodic channel state information CSI report configured for the network, and this triggering state can be used to indicate whether there is an aperiodic CSI report triggered in the aperiodic CSI report configured for the network and / or at least one target aperiodic CSI report is triggered in the aperiodic CSI report configured for the network.

[0077] It should be noted that the target aperiodic CSI report may refer to the aperiodic CSI report triggered by the first DCI in the network-configured aperiodic CSI report. In addition, regarding whether there is an aperiodic CSI report triggered in the network-configured aperiodic CSI report, it can be understood that the embodiments of the present application can determine whether there is an aperiodic CSI report triggered in the network-configured aperiodic CSI report according to the first DCI, so as to implement a processing mechanism for aperiodic channel state information (i.e., whether there is an aperiodic CSI report triggered) through the first DCI. Similarly, regarding that at least one target aperiodic CSI report is triggered in the network-configured aperiodic CSI report, it can be understood that the embodiments of the present application can determine that at least one target aperiodic CSI report is triggered in the network-configured aperiodic CSI report according to the first DCI, so as to implement a processing mechanism for aperiodic channel state information (i.e., which aperiodic CSIs are triggered) through the first DCI.

[0078] Specifically, whether there is an aperiodic CSI report triggered in the network-configured aperiodic CSI report can be determined by the beam type indicated by the first DCI; whether at least one target aperiodic CSI report is triggered in the network-configured aperiodic CSI report can be determined by the QCL type D reference signal in the TCI state indicated by the first DCI; or, whether at least one target aperiodic CSI report is triggered in the network-configured aperiodic CSI report can be determined by the QCL type D reference signal in other activated TCI states except for the QCL type D reference signal in the TCI state indicated by the first DCI and / or the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI; or, whether at least one target aperiodic CSI report is triggered in the network-configured aperiodic CSI report can be determined by the SSB associated with the QCL type D reference signal in the TCI state indicated by the first DCI. It should be noted that this part of the content will be described in detail later.

[0079] Specifically, the first DCI does not include a CSI request field.

[0080] It can be understood that the first DCI of the embodiments of the present application may include fields other than the CSI request field (i.e., the remaining fields). Among them, the remaining fields may include at least one of the following fields: TCI field, frequency domain resource indication information field, beam indication information field, etc. That is to say, the first DCI may include a beam indication information field, may include a TCI field, may include a frequency domain resource indication field, may include a TCI field, a frequency domain resource indication information field, a beam indication information field, etc., and no specific limitation is made thereto. Therefore, the first DCI may not be able to explicitly trigger an aperiodic CSI report.

[0081] Specifically, the first DCI includes a TCI field.

[0082] It should be noted that the TCI field in the first DCI can be used to indicate the TCI state in the activated TCI state. The activated TCI state can refer to the TCI state activated by an activation command (such as a MAC CE) sent by a network device.

[0083] S220. The terminal obtains the first DCI from the network device.

[0084] S230. The terminal determines the triggering state of the network-configured aperiodic channel state information (CSI) report according to the first DCI.

[0085] It should be noted that the standard protocol formulated by 3GPP has conducted relevant research on CSI. For different DCI format types, since some DCIs may contain a CSI request field while others may not, in the case where the network device only sends a DCI that does not contain a CSI request field, it may not be possible to explicitly trigger an aperiodic CSI report only through this DCI. Therefore, the network device usually needs to send another DCI containing a CSI request field to trigger the aperiodic CSI report. However, the method of sending another DCI will lead to problems such as increased system signaling overhead, reduced system resource utilization, and lower system deployment flexibility. Therefore, further research is needed on the triggering problem of aperiodic CSI reports.

[0086] Based on this, the embodiments of this application consider that the network device sends the first DCI, and the terminal determines the triggering state of the network-configured aperiodic CSI report according to the first DCI. Since the triggering state can be used to indicate whether there is an aperiodic CSI report triggered in the network-configured aperiodic CSI report and / or whether at least one target aperiodic CSI report is triggered in the network-configured aperiodic CSI report, the processing mechanism for aperiodic channel state information (that is, whether there is an aperiodic CSI report triggered and / or which aperiodic CSI reports are triggered in the network-configured aperiodic CSI report) is implemented through the triggering state determined by the first DCI, thereby realizing the implicit triggering of aperiodic CSI reports, which is beneficial to reducing system signaling overhead, improving system resource utilization, and ensuring high system deployment flexibility.

[0087] Next, the embodiments of this application will specifically describe the technical solutions involved in the above method.

[0088] Specifically, the first DCI can be used to indicate at least one of a downlink beam, an uplink beam, a downlink common beam, and an uplink common beam.

[0089] It should be noted that the wireless communication system according to the embodiments of the present application can support beam communication between a terminal and a network device. Among them, a beam can refer to the signal intensity distribution formed by a signal in different directions in space. In a wireless communication system that supports beam communication, the terminal and the network device can have multiple antennas or antenna arrays to allow beamforming. Based on this, the first DCI according to the embodiments of the present application can be used to indicate at least one of a downlink beam, an uplink beam, a downlink common beam, and an uplink common beam. For example, DCI format 1_1 / 1_2 can be used to indicate a downlink common beam and / or an uplink common beam.

[0090] It should be further noted that the beam according to the embodiments of the present application can be characterized by a QCL-TypeD reference signal.

[0091] Specifically, the triggering state can include at least one of the following: an aperiodic CSI report is triggered in the network-configured aperiodic CSI report, no aperiodic CSI report is triggered in the network-configured aperiodic CSI report, and at least one target aperiodic CSI report in the network-configured aperiodic CSI report is triggered.

[0092] It should be noted that since the triggering state in the embodiments of the present application can be used to indicate whether an aperiodic CSI report is triggered in the network-configured aperiodic CSI report and / or at least one target aperiodic CSI report is triggered in the network-configured aperiodic CSI report, the triggering state determined by the first DCI can be at least one of an aperiodic CSI report is triggered, no aperiodic CSI report is triggered, and at least one target aperiodic CSI report is triggered. Hereinafter, the embodiments of the present application will specifically describe various situations where the target aperiodic CSI report exists.

[0093] Situation 1:

[0094] In a possible example, the QCL-TypeD reference signal associated with the channel measurement resource associated with the target aperiodic CSI report is the same as the QCL-TypeD reference signal in the TCI state indicated by the first DCI.

[0095] It should be noted that for the "association" in the embodiments of the present application, the "association" can be understood as having an association relationship or a mapping relationship with each other. Among them, the association relationship or the mapping relationship can be determined by the configuration information for CSI sent by the network device to the terminal (i.e., defined by CSI-MeasConfig, CSI-ResourceConfig, or CSI-ReportConfig). Therefore, for the channel measurement resources associated with the target aperiodic CSI report, it can be understood that the terminal can determine the association relationship between the target aperiodic CSI report and the channel measurement resources through this configuration information.

[0096] In addition, for the QCL-TypeD reference signal associated with the channel measurement resources, first, each TCI state can give (include) one or two QCL type parameters. If the TCI state includes two QCL type parameters, the two QCL type parameters may include the QCL-TypeD reference signal. That is to say, the QCL-TypeD reference signal is configured in the TCI state. Second, the channel measurement resources themselves can be reference signals, and any one reference signal may be configured or associated with a TCI state to obtain the QCL-TypeD reference signal given by the TCI state. Therefore, in the embodiments of the present application, the reference signal can be determined through the channel measurement resources, and the QCL-TypeD reference signal can be obtained through the TCI state configured or associated with the reference signal, so as to establish the association relationship between the channel measurement resources and the QCL-TypeD reference signal.

[0097] Similarly, for the QCL-TypeD reference signal associated with the QCL-TypeD reference signal, based on the above, the QCL-TypeD reference signal may also be configured or associated with a TCI state, and then the QCL-TypeD reference signal given by the TCI state is obtained through the TCI state, so as to establish the association relationship between the QCL-TypeD reference signal and the QCL-TypeD reference signal. In short, the subsequent "association" can be understood through the above description, and will not be elaborated here.

[0098] Further, it should be noted that, based on the descriptions in the above "channel state information", "CSI report", "quasi co-location", and "antenna port quasi co-location", the network device configures the configuration information for CSI for the terminal, such as the CSI-RS resources for CSI measurement, the configuration information for CSI reporting, etc. Therefore, through this configuration information, the aperiodic CSI report configured by the network is usually associated with channel measurement resources (such as CSI-RS resources, CSI-IM resources, NZP-CSI-RS resources, CSI-SSB resources, etc.), and this channel measurement resource is also associated with the QCL type D reference signal (i.e., the downlink reference signal of QCL type D). At the same time, the TCI field in the DCI can indicate the TCI state from the activated TCI states activated by the network, and the indicated TCI state gives one or two QCL types.

[0099] Based on this, in the embodiment of this application, first, it is determined whether the QCL-TypeD reference signal (the beam can be characterized by the QCL-TypeD reference signal) in the TCI state indicated by the TCI field in the first DCI sent by the network device is the same as the QCL-TypeD reference signal associated with the channel measurement resources associated with the aperiodic CSI reports in the aperiodic CSI reports configured by the network. Then, the same aperiodic CSI report is used as the target aperiodic CSI report for triggering. Thus, the aperiodic CSI report is implicitly triggered through the first DCI and the configuration information configured by the network for CSI (the configuration information has the above various association relationships), which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0100] Case 2:

[0101] In a possible example, the QCL type D reference signal associated with the QCL type D reference signal associated with the channel measurement resources associated with the target aperiodic CSI report is the same as the QCL type D reference signal in the TCI state indicated by the first DCI.

[0102] It should be noted that, based on the above, it can be similarly known that the TCI field in the DCI can indicate the TCI state from the activated TCI states activated by the network, and the indicated TCI state will give one or two QCL type parameters (such as the QCL-TypeD reference signal). In addition, since the QCL-TypeD reference signal associated with the channel measurement resource associated with the aperiodic CSI report configured by the network is also associated with the QCL-TypeD reference signal, therefore, in the embodiments of the present application, first, it is determined which aperiodic CSI reports in the aperiodic CSI reports associated with the channel measurement resources associated with the QCL-TypeD reference signal associated with the QCL-TypeD reference signal in the TCI state indicated by the TCI field in the first DCI sent by the network device are the same as the QCL-TypeD reference signal associated with the QCL-TypeD reference signal, and then the same aperiodic CSI report is used as the target aperiodic CSI report for triggering, so as to implicitly trigger the aperiodic CSI report through the first DCI and the configuration information configured by the network for CSI, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0103] Case 3:

[0104] In a possible example, the QCL-TypeD reference signal associated with the QCL-TypeD reference signal associated with the channel measurement resource associated with the target aperiodic CSI report is the same as the QCL-TypeD reference signal associated with the QCL-TypeD reference signal in the TCI state indicated by the first DCI.

[0105] It should be noted that, based on the above, it can be similarly known that since the QCL-TypeD reference signal in the TCI state indicated by the first DCI is also associated with the QCL-TypeD reference signal, therefore, in the embodiments of the present application, first, it is determined which aperiodic CSI reports in the aperiodic CSI reports associated with the channel measurement resources associated with the QCL-TypeD reference signal associated with the QCL-TypeD reference signal in the TCI state indicated by the TCI field in the first DCI sent by the network device are the same as the QCL-TypeD reference signal associated with the QCL-TypeD reference signal, and then the same aperiodic CSI report is used as the target aperiodic CSI report for triggering, so as to implicitly trigger the aperiodic CSI report through the first DCI and the configuration information configured by the network for CSI, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0106] Case 4:

[0107] In a possible example, the QCL type D reference signal associated with the channel measurement resource associated with the target aperiodic CSI report is the same as the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI.

[0108] It should be noted that, based on the above by the same token, in the embodiment of the present application, first, it is determined which QCL type D reference signals associated with the QCL type D reference signals in the TCI state indicated by the TCI field in the first DCI sent by the network device are the same as the QCL type D reference signals associated with the channel measurement resources associated with the aperiodic CSI reports in the network-configured aperiodic CSI reports, and then the same aperiodic CSI reports are used as the target aperiodic CSI reports for triggering, so as to implicitly trigger the aperiodic CSI reports through the first DCI and the configuration information configured by the network for CSI, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0109] Case 5:

[0110] In a possible example, the QCL type D reference signal associated with the channel measurement resource associated with the target aperiodic CSI report is the same as at least one of the QCL type D reference signals in other active TCI states except for the QCL type D reference signal in the TCI state indicated by the first DCI and / or the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI.

[0111] It should be noted that, based on the descriptions in the above "channel state information", "CSI report", "quasi co-location", and "antenna port quasi co-location", the network device can first activate the TCI state for the terminal through an activation command (such as MAC CE), and then indicate the TCI state from the activated TCI state through the TCI field in the DCI sent down. Therefore, in the embodiments of the present application, first, by determining at least one of the QCL-TypeD parameters in other activated TCI states except for the QCL-TypeD reference signal in the TCI state indicated by the TCI field in the first DCI sent down by the network device and / or the QCL-TypeD reference signal associated with the QCL-TypeD reference signal in the TCI state indicated by the TCI field in the first DCI sent down by the network device is the same as the QCL-TypeD reference signal associated with the channel measurement resource associated with which aperiodic CSI report in the network-configured aperiodic CSI report, and then using the same aperiodic CSI report as the target aperiodic CSI report for triggering, so as to implicitly trigger the aperiodic CSI report through the first DCI and the configuration information configured by the network for CSI, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0112] Scenario 6:

[0113] In a possible example, the synchronization signal block SSB associated with the QCL-TypeD reference signal associated with the channel measurement resource associated with the target aperiodic CSI report satisfies the correlation threshold with the SSB associated with the QCL-TypeD reference signal in the TCI state indicated by the first DCI.

[0114] Among them, the correlation threshold is configured by the network or pre-configured.

[0115] It should be noted that, based on the same principle as above, since the QCL-TypeD reference signal is also associated with the SSB, in the embodiments of the present application, first, by determining whether the SSB associated with the QCL-TypeD reference signal in the TCI state indicated by the TCI field in the first DCI sent down by the network device satisfies the correlation threshold with the SSB associated with the QCL-TypeD reference signal associated with the channel measurement resource associated with which aperiodic CSI report in the network-configured aperiodic CSI report. Among them, satisfying the correlation threshold means having a relatively high correlation (such as higher than the correlation threshold) or a relatively low correlation (such as lower than the correlation threshold). Then, using the aperiodic CSI report that satisfies the correlation threshold as the target aperiodic CSI report for triggering, so as to implicitly trigger the aperiodic CSI report through the first DCI and the configuration information configured by the network for CSI, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0116] Based on the above descriptions of various situations of the target aperiodic CSI report, in the study of the triggering problem of aperiodic channel state information reporting, those skilled in the art can conceive that the network has pre-configured the configuration information for CSI to the terminal in advance, so that the terminal can implicitly trigger the aperiodic CSI report through the first DCI sent by the network device and the pre-configured configuration information for CSI. That is to say, before S210, the terminal obtains the configuration information for CSI from the network device, which will not be elaborated here.

[0117] Combined with the above description, the embodiments of the present application will further describe the resources carrying the target aperiodic CSI report below.

[0118] In a possible example, if the first DCI is the DCI for downlink scheduling, the target aperiodic CSI report is carried by the PUCCH resource indicated by the first DCI.

[0119] It should be noted that since the DCI sent by the network device can include the DCI for uplink scheduling and the DCI for downlink scheduling, if the first DCI is the DCI for downlink scheduling, the terminal can send the target aperiodic CSI report to the network device through the PUCCH resource indicated by the first DCI, thereby realizing the reporting of aperiodic CSI.

[0120] In a possible example, if the first DCI is the DCI for uplink scheduling, the target aperiodic CSI report is carried by the PUSCH resource, and the PUSCH resource is determined by the frequency-domain resource indication information in the first DCI and the configuration information of the CSI report.

[0121] It can be understood that if the first DCI is the DCI for uplink scheduling, the terminal can send the target aperiodic CSI report to the network device through the PUSCH resource determined by the frequency-domain resource indication information in the first DCI and the configuration information of the CSI report (such as defined by CSI-ReportConfig), thereby realizing the reporting of aperiodic CSI.

[0122] Combined with the above description, the embodiments of the present application will specifically describe how to determine the triggering status of the aperiodic CSI report configured for the network according to the first DCI.

[0123] Method 1:

[0124] In a possible example, determining the triggering status of the aperiodic channel state information CSI report configured for the network according to the first DCI may include the steps of: the terminal determines the triggering status according to the beam type indicated by the first DCI.

[0125] Among them, the beam types indicated by the first DCI include at least one of a downlink beam, an uplink beam, a downlink common beam, and an uplink common beam.

[0126] It should be noted that the terminal determines the triggering state according to the beam type indicated by the first DCI. It can also be understood that the terminal determines whether an aperiodic CSI report in the network-configured aperiodic CSI report is triggered according to the beam type indicated by the first DCI. It can be seen that in the embodiment of the present application, the triggering state of the network-configured aperiodic CSI report is determined by the beam type indicated by the first DCI, so as to implement a processing mechanism for aperiodic CSI through the triggering state (that is, whether an aperiodic CSI report in the network-configured aperiodic CSI report is triggered), and then implicitly trigger the aperiodic CSI report, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0127] Specifically, determining the triggering state according to the beam type indicated by the first DCI may include the following steps: If the beam type indicated by the first DCI is a downlink beam, the terminal determines that the triggering state is that an aperiodic CSI report in the network-configured aperiodic CSI report is triggered; or, if the beam type indicated by the first DCI is an uplink beam, the terminal determines that the triggering state is that no aperiodic CSI report in the network-configured aperiodic CSI report is triggered.

[0128] It should be noted that the terminal usually reports after performing channel measurement through a reference signal transmitted on the downlink (such as CSI-RS). Therefore, if the first DCI indicates a downlink beam, and the beam can be characterized by a QCL-TypeD reference signal, there may be a situation of measurement of the reference signal and triggering of an aperiodic CSI report; if the first DCI indicates an uplink beam, since there is no need to report the channel measurement on the uplink, there may be no situation of triggering an aperiodic CSI report.

[0129] Method 2:

[0130] In a possible example, determining the triggering state of the network-configured aperiodic channel state information CSI report according to the first DCI may include the following steps: The terminal determines the triggering state according to the QCL type D reference signal in the TCI state indicated by the first DCI.

[0131] It should be noted that, based on the above same principle, it can be known that since the QCL type D reference signal in the TCI state indicated by the TCI field in the first DCI sent by the network device may be the same as the QCL type D reference signal associated with the channel measurement resource associated with the network-configured aperiodic CSI report, therefore, in the embodiments of the present application, the QCL type D reference signal in the TCI state indicated by the first DCI is used to determine the trigger state, so as to implement a processing mechanism for aperiodic channel state information through the trigger state (that is, which aperiodic CSI reports in the network-configured aperiodic CSI report are triggered), and further implement implicitly triggering the aperiodic CSI report, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0132] Specifically, determining the trigger state according to the QCL type D reference signal in the TCI state indicated by the first DCI may include the following steps: If the QCL type D reference signal in the transmission configuration indication TCI state indicated by the first DCI is the same as the QCL type D reference signal associated with the channel measurement resource associated with at least one target aperiodic CSI report in the network-configured aperiodic CSI report, the terminal determines that the trigger state is that at least one target aperiodic CSI report is triggered.

[0133] Specifically, determining the trigger state according to the QCL type D reference signal in the TCI state indicated by the first DCI may include the following steps: If the QCL type D reference signal associated with the QCL type D reference signal in the transmission configuration indication TCI state indicated by the first DCI is the same as the QCL type D reference signal associated with the channel measurement resource associated with at least one target aperiodic CSI report in the network-configured aperiodic CSI report, the terminal determines that the trigger state is that at least one target aperiodic CSI report is triggered.

[0134] Specifically, determining the trigger state according to the QCL type D reference signal in the TCI state indicated by the first DCI may include the following steps: If the QCL type D reference signal of the QCL type D reference signal in the TCI state indicated by the first DCI is the same as the QCL type D reference signal associated with the channel measurement resource associated with at least one target aperiodic CSI report in the network-configured aperiodic CSI report, the terminal determines that the trigger state is that at least one target aperiodic CSI report is triggered.

[0135] Specifically, determining the triggering state based on the QCL type D reference signal in the TCI state indicated by the first DCI may include the following steps: If the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI is the same as the QCL type D reference signal associated with the channel measurement resource of at least one target aperiodic CSI report in the network-configured aperiodic CSI report, the terminal determines that the triggering state is that at least one target aperiodic CSI report is triggered.

[0136] Method 3:

[0137] In a possible example, determining the triggering state for a network-configured aperiodic channel state information (CSI) report according to the first DCI may include: The terminal determines the triggering state based on the QCL type D reference signal in other active TCI states except for the QCL type D reference signal in the TCI state indicated by the first DCI and / or the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI.

[0138] It should be noted that based on the above, similarly, since the QCL type D reference signal in other active TCI states except for the QCL type D reference signal in the TCI state indicated by the TCI field in the first DCI sent by the network device and / or the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI may be the same as at least one of the QCL type D reference signals associated with the channel measurement resources of the network-configured aperiodic CSI report, therefore, in the embodiments of the present application, the triggering state is determined by the QCL type D reference signal in other active TCI states except for the QCL type D reference signal in the TCI state indicated by the first DCI and / or the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI, so as to implement a processing mechanism for aperiodic channel state information (that is, which aperiodic CSI reports in the network-configured aperiodic CSI report are triggered) through the triggering state, and further implement implicitly triggering the aperiodic CSI report, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0139] Specifically, determining the triggering state based on the QCL type D reference signal in the activated TCI state other than the QCL type D reference signal in the TCI state indicated by the first DCI and / or the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI may include the following steps: If at least one of the QCL type D reference signals in the activated TCI state other than the QCL type D reference signal in the TCI state indicated by the first DCI and / or the QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI is the same as at least one of the QCL type D reference signals associated with the channel measurement resources associated with at least one target aperiodic CSI report in the network-configured aperiodic CSI report, the terminal determines that the triggering state is that at least one target aperiodic CSI report is triggered.

[0140] Method 4:

[0141] In a possible example, determining the triggering state for the network-configured aperiodic channel state information (CSI) report according to the first DCI may include the following steps: The terminal determines the triggering state based on the SSB associated with the QCL type D reference signal in the TCI state indicated by the first DCI.

[0142] It should be noted that based on the above, it can be similarly known that since the SSB associated with the QCL type D reference signal in the TCI state indicated by the TCI field in the first DCI sent by the network device may satisfy the correlation threshold with the SSB associated with the QCL type D reference signal associated with the channel measurement resources associated with the network-configured aperiodic CSI report, therefore, in the embodiments of the present application, the triggering state is determined based on the SSB associated with the QCL type D reference signal in the TCI state indicated by the first DCI, so as to implement a processing mechanism for aperiodic channel state information (that is, which aperiodic CSI reports in the network-configured aperiodic CSI report are triggered) through the triggering state, and further implement implicitly triggering the aperiodic CSI report, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0143] Specifically, determining the triggering state based on the SSB associated with the QCL type D reference signal in the TCI state indicated by the first DCI may include the following steps: If the SSB associated with the QCL type D reference signal in the TCI state indicated by the first DCI satisfies the correlation threshold with the SSB associated with the QCL type D reference signal associated with the channel measurement resources associated with at least one target aperiodic CSI report in the network-configured aperiodic CSI report, the terminal determines that the triggering state is that at least one target aperiodic CSI report is triggered.

[0144] It can be seen that in the embodiment of the present application, first, the network device sends the first DCI to the terminal. Then, the terminal obtains the first DCI from the network device and determines the triggering status of the aperiodic CSI report configured for the network according to the first DCI. Finally, since the triggering status is used to indicate whether an aperiodic CSI report in the network-configured aperiodic CSI report is triggered and / or at least one target aperiodic CSI report in the network-configured aperiodic CSI report is triggered, the processing mechanism for the aperiodic channel state information (i.e., whether an aperiodic CSI report in the network-configured aperiodic CSI report is triggered and / or which aperiodic CSI reports are triggered) is implemented through the triggering status determined by the first DCI, thereby implicitly triggering the aperiodic CSI report, which is beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high system deployment flexibility.

[0145] The above mainly introduces the solution of the embodiment of the present application from the perspective of the method side. It can be understood that in order for the terminal or the network device to implement the above functions, it includes the corresponding hardware structure and / or software module for executing each function. Those skilled in the art should easily realize that, combining the units and algorithm steps of each example described in the embodiments disclosed in this article, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed in the way of hardware or computer software driving the hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0146] The embodiment of the present application can perform a functional unit division on the terminal or the network device according to the above method examples. For example, each functional unit can be divided corresponding to each function, or two or more functions can be integrated into one processing unit. The above integrated unit can be implemented in the form of hardware or in the form of a software program module. It should be noted that the division of units in the embodiment of the present application is illustrative, only a logical function division, and there may be other division methods in actual implementation.

[0147] In the case of adopting an integrated unit, Figure 3 a block diagram of the functional units of a device for aperiodic channel state information reporting is provided. The device 300 for aperiodic channel state information reporting includes: a processing unit 302 and a communication unit 303. The processing unit 302 is used to control and manage the actions of the terminal. For example, the processing unit 302 is used to support the terminal to execute Figure 2The steps therein and other processes for the technical solutions described in this application. The communication unit 303 is used to support communication between the terminal and other devices in the wireless communication system. The apparatus 300 for aperiodic channel state information reporting may further include a storage unit 301 for storing the program code executed by the apparatus 300 for aperiodic channel state information reporting and the transmitted data.

[0148] It should be noted that the apparatus 300 for aperiodic channel state information reporting may be a chip or a chip module.

[0149] Among them, the processing unit 302 may be a processor or a controller. For example, it may be a central processing unit (CPU), a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof. It can implement or execute various exemplary logic blocks, modules, and circuits described in connection with the disclosure of this application. The processing unit 302 may also be a combination that implements computing functions, such as a combination including one or more microprocessors, a combination of a DSP and a microprocessor, and so on. The communication unit 303 may be a communication interface, a transceiver, a transceiver circuit, etc., and the storage unit 301 may be a memory. When the processing unit 302 is a processor, the communication unit 303 is a communication interface, and the storage unit 301 is a memory, the apparatus 300 for aperiodic channel state information reporting involved in the embodiments of this application may be Figure 5 the terminal shown.

[0150] Specifically, the processing unit 302 is used to execute any step performed by the terminal in the above method embodiments, and when performing data transmission such as sending, it can optionally call the communication unit 303 to complete the corresponding operation. A detailed description is given below.

[0151] The processing unit 302 is used to: obtain a first downlink control information DCI from a network device; determine, according to the first DCI, a triggering state for an aperiodic channel state information CSI report configured by the network, where the triggering state is used to indicate whether there is an aperiodic CSI report triggered in the aperiodic CSI report configured by the network and / or whether at least one target aperiodic CSI report is triggered in the aperiodic CSI report configured by the network.

[0152] It should be noted that Figure 3For the specific implementation of each operation in the foregoing embodiments, reference may be made to the description in the foregoing method embodiment shown in Figure 2 and details are not described herein again.

[0153] It can be seen that in the embodiments of the present application, by obtaining a first DCI from a network device and determining, according to the first DCI, a triggering state of an aperiodic CSI report configured for the network. Since the triggering state is used to indicate whether there is an aperiodic CSI report triggered in the aperiodic CSI report configured for the network and / or whether at least one target aperiodic CSI report in the aperiodic CSI report configured for the network is triggered, the triggering state determined by the first DCI is used to implement a processing mechanism for aperiodic channel state information (that is, whether there is an aperiodic CSI report triggered in the aperiodic CSI report configured for the network and / or which aperiodic CSI reports are triggered), so as to implicitly trigger the aperiodic CSI report, which is beneficial to reducing system signaling overhead, improving system resource utilization, and ensuring high system deployment flexibility.
