Background

A standard protocol established by the third generation partnership project (3 GPP) has been studied on Channel State Information (CSI). In New Radio (NR) version 15(Release15, R15) or R16 phase, for aperiodic CSI report (report), the terminal needs to know whether aperiodic CSI report is triggered and which aperiodic CSI report is triggered through a CSI request field (CSI request field) in Downlink Control Information (DCI).

However, in the NR R17 stage, for different DCI format types, a part of DCI may not carry a CSI request field, so that the part of DCI cannot implement triggering of an aperiodic CSI report, and therefore further research is needed for the triggering problem of the aperiodic CSI report.

Optionally, the wireless communication system of the embodiment of the present application may be applied to an unlicensed spectrum. The unlicensed spectrum may also be referred to as a shared spectrum. Alternatively, the wireless communication system in the present embodiment may also be applied to a licensed spectrum. The licensed spectrum may also be considered as an unshared spectrum.

Since the embodiments of the present application are described in conjunction with a terminal and a network device, the terminal, a relay device, and a network device will be described in detail below.

Specifically, the terminal may be a User Equipment (UE), a remote terminal (remote UE), a relay UE, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote station, a mobile device, a user terminal, a smart terminal, a wireless communication device, a user agent, or a user equipment. It should be noted that the relay device is a terminal capable of providing a relay forwarding service for other terminals (including a remote terminal). In addition, the terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a next generation communication system (e.g., NR communication system, 6G communication system), or a terminal in a Public Land Mobile Network (PLMN) that is evolved in the future, and the like, which are not particularly limited.

Further, the terminal can be deployed on land, including indoors or outdoors, hand-held, worn, or vehicle-mounted; can be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.).

Further, the terminal may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned autonomous driving, a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city (smart city), or a wireless terminal in smart home (smart home), and the like.

Specifically, the network device may be a device for communicating with the terminal, and is responsible for radio resource management, quality of service (QoS) management, data compression and encryption, data transmission and reception, and the like on the air interface side. The network device may be a Base Station (BS) in a communication system or a device deployed in a Radio Access Network (RAN) for providing a wireless communication function.

In addition, the AAU implements part of the physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling (e.g., RRC layer signaling) can be considered to be sent by the DU or sent by the DU and the AAU in the network deployment. It is to be understood that the network device may comprise at least one of a CU, a DU, an AAU.

Before describing the method for aperiodic csi reporting provided in the embodiments of the present application in detail, relevant contents related to the embodiments of the present application are described again.

1. Channel State Information (CSI)

The protocol standards set by the third generation partnership project (3 GPP) have been studied with respect to CSI. The CSI is channel state information used by the terminal to feed back the downlink channel quality to the network device, so that the network device selects a suitable Modulation and Coding Scheme (MCS) for downlink data transmission, reduces the block error rate (BLER) of downlink data transmission, and performs corresponding beam management, mobility management, adaptive tracking, rate matching, and the like. Wherein, the CSI includes a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a CSI reference signal resource indicator (CRI), a Synchronization Signal Block Resource Indicator (SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), a layer 1reference signal received power (L1-RSRP), etc., and time-frequency domain resources required for CSI transmission are configured by the network device. In addition, the relevant configuration information for CSI may be defined by the higher layer parameter CSI-MeasConfig. Wherein, the CSI-MeasConfig defines parameters CSI-ResourceConfig and CSI-report Config. The CSI-ResourceConfig can be used for configuring CSI-RS resources for CSI measurement; the CSI-ReportConfig may be used to configure how the CSI is reported (i.e., configuration information for CSI reporting).

First, the CSI-ResourceConfig may configure a set of resources (ResourceSet), which may contain the most basic CSI-RS resources (CSI-RS-Resource). The CSI-RS-Resource may include nzp-CSI-RS Resource, SSB, and CSI interference management (CSI-IM) Resource. Wherein the type of CSI-RS resource may be periodic, semi-persistent, or aperiodic.

Secondly, the resource for channel measurement, the CSI-IM-resource for interference and the nzp-CSI-RS-resource for interference in the CSI-ReportConfig may represent CSI-ResourceConfigId for channel measurement (channel measurement) and interference measurement (interference measurement), and the CSI-ResourceConfigId has an association relationship with the CSI-ResourceConfig, thereby acquiring CSI-RS resources for CSI measurement.

Finally, reportConfigType in CSI-ReportConfig may be used to configure the type of CSI report. The CSI may be reported through a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH). The types of CSI reports can be divided into: periodic (PUCCH reporting CSI), aperiodic (PUSCH reporting CSI), semi-persistent on PUCCH (semi persistent), and semi-persistent on PUSCH. For the aperiodic CSI report and the semi-persistent CSI report on the PUSCH, the network side may also configure TriggerState and reportTriggerSize to cooperate with the CSI request field in the DCI.

2. CSI report (report)

Periodic CSI: after the periodical CSI-RS Resource and Report parameters are configured through RRC, the periodical CSI-RS Resource and Report parameters can take effect immediately without activating or triggering CSI-RS transmission and CSI Report through MAC-CE/DCI.

Semi-persistent CSI reporting on PUCCH: if the semi-continuous CSI-RS transmission is configured through RRC, the CSI-RS transmission needs to be activated through the MAC CE1, and then a CSI report is activated through the MAC CE 2; if the periodic CSI-RS transmission is configured by RRC, the CSI-RS transmission does not need to be activated by the MAC CE1, but only the CSI report needs to be activated by the MAC CE 2.

PUSCH semi-persistent CSI reporting: if the semi-continuous CSI-RS transmission is configured through RRC, the CSI-RS transmission needs to be activated through MAC CE1, and then a CSI report is triggered through DCI; if the periodic CSI-RS transmission is configured by RRC, MAC CE1 is not required to activate CSI-RS transmission, but rather only to trigger CSI reporting through DCI. It should be noted that, for the DCI, the DCI may be a DCI format (format)0_1 scrambled by using SP-CSI-RNTI (semi-persistent CSI RNTI), and a CSI request (request) field (field) in the DCI may be associated with a corresponding trigger state (TriggerState) through setting of a code point (codepoint), where the TriggerState may define an associated CSI-reportconfiguration, so that a parameter CSI-reportconfiguration (configuration information of a CSI report) associated with a semi-persistent CSI report on a PUSCH may be found through the TriggerState.

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, which is similar to the process of semi-persistent CSI reporting described above. When the corresponding trigger is disassociated through codepoint of the CSI request field in the DCI format 0_1/0_2, if the value of the CSI request field is 000, the half-period CSI report is not required to be triggered, which is different from the DCI trigger in the semi-persistent CSI report; if the value of the CSI request field is 001, it indicates that the aperiodic CSI report associated with TriggerState1 is triggered, and so on. After associating TriggerState, the terminal may obtain two important parameters: CSI-ReportConfig and resourceSet. Wherein the NZP-CSI-RS-resource set in the resource set is used for channel measurement.

3. Quasi Co-Location (Quasi Co-Location, QCL)

In order to ensure correct receiving and demodulation of signals, a standard protocol introduces a reference signal concept with a Quasi Co-Location (QCL) relationship, such as CSI-RS, so that a terminal can estimate large-scale characteristic parameters according to the CSI-RS. The large-scale characteristic parameters comprise at least one of delay spread, Doppler frequency shift, average gain, average delay, space domain information and the like. For example, in R11 of the LTE communication system, the standard protocol introduces an antenna port QCL. The antenna port QCL may indicate that the signals transmitted by the antenna ports will experience the same large scale fading and thus have 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 signal on antenna port a are also suitable for the signal on antenna port B.

In addition, in the NR communication system, a terminal and a network device may configure a large-scale array structure of multiple antenna panels, and large-scale characteristics of beams formed by different antenna panels may be different. At this time, the large-scale characteristic parameters include reception angle of arrival (AOA), Angle of Arrival Spread (AAS), angle of departure Angle (AOD), departure angle spread (ADS), spatial correlation (spatialircorrelation), and the like, in addition to the delay spread, doppler shift, average gain, and average delay described above.

4. Antenna port quasi co-location

A maximum of M transmission configuration indication states (TCIstate) may be configured for the terminal in the higher layer parameter PDSCH-configuration for decoding the PDSCH according to the detected DCI in the PDCCH, M depending on the terminal capability. Each TCI state contains parameters for configuring a QCL relationship between one or two downlink reference signals (e.g., CSI-RS and/or SSB) and a demodulation reference signal (DM-RS) port of the PDSCH, a DM-RS port of the PDCCH, or a CSI-RS port of the CSI-RS resource. The QCL relationship may be configured by a higher 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, the QCL types associated with the two downlink reference signals should not be the same, whether or not they are the same reference signal. Wherein the QCL Type associated with each downlink reference signal is defined by a higher layer parameter QCL-Type in QCL-Info and may take one of the following values:

QCL type A (QCL-type A) { Doppler shift, Doppler spread, average delay, delay spread };

QCL type B (QCL-type B): Doppler shift, Doppler spread };

QCL type C (QCL-type C): Doppler shift, average delay };

QCL type D (QCL-type): spatial reception parameters.

Wherein the spatial reception parameter may include at least one of: AOA, average AOA, AOA extension, AOD, average AOD, AOD extension, receive antenna spatial correlation, transmit beam, receive beam, resource identification, and the like. Further, when the QCL type is QCL-type, the TCI status may be used to indicate a beam. Meanwhile, each TCI state may give (contain) 1 or 2 QCL type parameters. If the TCI state contains 2 QCL type parameters, the QCL type will contain a QCL-TypeD reference signal. That is, the QCL-TypeD reference signal is configured in the TCI state.

Secondly, the TCI status may be activated by an activation command (e.g., MAC control element CE) issued by the network side and indicated by the TCI field in the DCI. For example, when TCI status is used for QCL type indication for PDSCH, the network device may first activate 2 via MAC CE^NThe TCI state is activated and then the TCI word of N bits in DCI is passedSegment from the 2^NOne of the active TCI states indicates a TCI state. When N is 3, if the TCI field in the DCI takes the value '000', the TCI indicates the first TCI state activated by the MAC CE. In addition, the reference signals of the TCI state are QCL with the DM-RS port of PDSCH with respect to the QCL type parameters given by the TCI state.

In summary, for the triggering problem of the aperiodic CSI report, since some DCI (e.g., DCI format 0_1/0_2) carries the CSI request field, the terminal may know whether the aperiodic CSI report exists and which aperiodic CSI reports are triggered through the CSI request field in the some DCI. For example, when the CSI request field bit width in the DCI format 0_1/0_2 is 3 bits, if the CSI request field value is "000", it indicates that no aperiodic CSI report is triggered; if the value of the CSI request field is 001, it indicates that the aperiodic CSI report associated with TriggerState1 associated with the CSI request field is triggered.

However, in the NR 17 stage, since another part of DCI (e.g. DCI format 1_1/1_2) may not include (carry) the CSI request field, the other part of DCI cannot implement triggering of aperiodic CSI report. It can be seen that further research is needed to address the triggering problem of aperiodic CSI reporting.

In conjunction with the above description, an embodiment of the present application provides a flowchart of a method for aperiodic csi reporting, please refer to fig. 2, where the method includes the following steps:

s210, the network equipment sends first downlink control information DCI to the terminal.

The first DCI may be configured to determine a trigger state for a network-configured aperiodic channel state information CSI report, where the trigger state may be used to indicate whether an aperiodic CSI report of a network configuration is triggered and/or at least one target aperiodic CSI report of the network-configured aperiodic CSI report is triggered.

It should be noted that the target aperiodic CSI report may refer to an aperiodic CSI report triggered by the first DCI in the aperiodic CSI report configured by the network. In addition, for whether an aperiodic CSI report in an aperiodic CSI report of a network configuration is triggered, it may be understood that, in the embodiment of the present application, it may be determined whether an aperiodic CSI report in an aperiodic CSI report of a network configuration is triggered according to the first DCI, so that a processing mechanism for aperiodic channel state information is implemented through the first DCI (i.e., whether an aperiodic CSI report is triggered). Similarly, for at least one target aperiodic CSI report in the aperiodic CSI reports configured by the network to be triggered, it may be understood that, in the embodiment of the present application, it may be determined that at least one target aperiodic CSI report in the aperiodic CSI reports configured by the network is triggered according to the first DCI, so that a processing mechanism for aperiodic channel state information (that is, which aperiodic CSI is triggered) is implemented through the first DCI.

Specifically, whether an aperiodic CSI report is triggered in the aperiodic CSI reports configured by the network may be determined by the beam type indicated by the first DCI; at least one target aperiodic CSI report in the network-configured aperiodic CSI reports is triggered may be determined by a QCL type D reference signal in the TCI state indicated by the first DCI; or, the at least one target aperiodic CSI report in the aperiodic CSI reports configured by the network may be triggered by a QCL type D reference signal in an activated TCI state other than the QCL type D reference signal in the TCI state indicated by the first DCI and/or a QCL type D reference signal associated with the QCL type D reference signal in the TCI state indicated by the first DCI; alternatively, the triggering of at least one target aperiodic CSI report among the aperiodic CSI reports configured by the network may 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 is described in detail later.

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

It may be understood that the first DCI of the embodiment of the present application may include fields (i.e., remaining fields) other than the CSI request field. Wherein the remaining fields may include at least one of the following fields: a TCI field, a frequency domain resource indication information field, a beam indication information field, etc. That is, the first DCI may include a beam indication information field, a TCI field, a frequency domain resource indication information field, a beam indication information field, and the like, which is not limited in particular. Therefore, the first DCI may not enable explicitly triggering aperiodic CSI reports.

Specifically, the first DCI includes a TCI field.

It is noted that the TCI field in the first DCI may be used to indicate an activated TCI state (TCI-state). The active TCI status may refer to a TCI status activated by an activation command (e.g., MAC CE) issued by the network device.

S220, the terminal acquires the first DCI from the network equipment.

S230, the terminal determines the trigger state of the aperiodic Channel State Information (CSI) report configured for the network according to the first DCI.

It should be noted that the standard protocol established by 3GPP has been studied on CSI. For different DCI format types, since some DCI may include a CSI request field and another DCI may not include the CSI request field, if the network device only issues DCI not including the CSI request field, currently, it may not be possible to explicitly trigger the aperiodic CSI report only through the DCI. For this reason, the network device generally needs to issue a DCI containing a CSI request field to trigger aperiodic CSI reporting. However, the DCI is issued again, which results in increased signaling overhead of the system, reduced utilization of system resources, and low flexibility of system deployment. Therefore, further research is needed to address the triggering problem of aperiodic CSI reporting.

Based on this, the network device issues the first DCI, and the terminal determines the trigger state of the aperiodic CSI report configured for the network according to the first DCI. Since the trigger state may be used to indicate whether an aperiodic CSI report is triggered in the aperiodic CSI reports of the network configuration and/or at least one target aperiodic CSI report is triggered in the aperiodic CSI reports of the network configuration, a processing mechanism for the aperiodic channel state information (i.e., whether an aperiodic CSI report is triggered and/or which aperiodic CSI reports are triggered in the aperiodic CSI reports of the network configuration) is implemented by the trigger state determined by the first DCI, so that the aperiodic CSI report is implicitly triggered, which is beneficial to reducing system signaling overhead, improving system resource utilization, and ensuring high system deployment flexibility.

The following embodiments of the present application will specifically describe the technical solutions involved in the above methods.

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

It should be noted that the wireless communication system of the embodiment of the present application may support beam communication between the terminal and the network device. Wherein, a beam (beam) may refer to a signal intensity distribution formed by signals in different directions in space. Terminals and network devices in wireless communication systems supporting beam communication may have multiple antennas or antenna arrays to allow beamforming. Based on this, the first DCI according to the embodiment of the present application may 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, the DCI format 1_1/1_2 may be used to indicate a downlink common beam and/or an uplink common beam.

It is further noted that the beams of the embodiments of the present application may be characterized by QCL-type reference signals.

Specifically, the trigger state may include at least one of: at least one target aperiodic CSI report in the aperiodic CSI reports configured by the network is triggered, no aperiodic CSI report in the aperiodic CSI reports configured by the network is triggered, and the aperiodic CSI reports configured by the network is triggered.

It should be noted that, since the trigger state in the embodiment of the present application may be used to indicate whether an aperiodic CSI report is triggered in an aperiodic CSI report of a network configuration and/or at least one target aperiodic CSI report is triggered in an aperiodic CSI report of a network configuration, the trigger state determined by the first DCI may be at least one of whether an aperiodic CSI report is triggered, no aperiodic CSI report is triggered, and at least one target aperiodic CSI report is triggered. The following embodiments of the present application will specifically describe various situations in which a target aperiodic CSI report exists.

Case 1:

in one possible example, the quasi-co-located 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 in the TCI state indicated by the first DCI.

It should be noted that, for "association" and "association" appearing in the embodiments of the present application, an association relationship or a mapping relationship may exist between the two. The association or mapping relationship may be determined by configuration information for CSI (defined by CSI-MeasConfig, CSI-ResourceConfig, or CSI-ReportConfig) sent by the network device to the terminal. Therefore, for the channel measurement resource associated with the target aperiodic CSI report, it can be understood that the terminal may determine the association relationship between the target aperiodic CSI report and the channel measurement resource through the configuration information.

In addition, for the QCL-TypeD reference signal associated with the channel measurement resource, first, 1 or 2 QCL type parameters may be given (contained) per TCI state. If the TCI status includes 2 QCL-type parameters, the 2 QCL-type parameters may include a QCL-type reference signal. That is, the QCL-TypeD reference signal is configured in the TCI state. Second, the channel measurement resources themselves may be reference signals, and any one of the reference signals may configure or associate a TCI state to obtain a QCL-TypeD reference signal given by the TCI state. Therefore, the embodiment of the application can determine the reference signal through the channel measurement resource, and acquire the QCL-TypeD reference signal through the TCI state configured or associated with the reference signal, thereby establishing the association relationship between the channel measurement resource and the QCL-TypeD reference signal.

Similarly, for the QCL-type reference signal associated with the QCL-type reference signal, based on the above description, the QCL-type reference signal may also configure or associate a TCI state, and then obtain the QCL-type reference signal given by the QCL-type reference signal through the TCI state, so as to establish an association relationship between the QCL-type reference signal and the QCL-type reference signal. In summary, the subsequent "association" can be known from the above description, and will not be described in detail.

It should be further noted that, as can be known from the descriptions in the above "channel state information", "CSI report", "quasi co-location", and "antenna port quasi co-location", the network device may configure configuration information for CSI, such as CSI-RS resource for CSI measurement, configuration information for CSI report, and the like, to the terminal. Thus, with this configuration information, aperiodic CSI reports configured by the network will typically be associated to channel measurement resources (e.g., CSI-RS resources, CSI-IM resources, NZP-CSI-RS resources, CSI-SSB resources, etc.), and the channel measurement resources will also be associated to QCL type D reference signals (i.e., downlink reference signals of QCL type D). Meanwhile, the TCI field in the DCI may indicate a TCI status from among activated TCI statuses activated by the network, and the indicated TCI status may give 1 or 2 QCL types.

Based on this, in the embodiment of the present application, it is first determined that a QCL-TpyeD reference signal (a beam may be characterized by a QCL-TypeD reference signal) in a TCI state indicated by a TCI field in a first DCI sent by a network device is the same as a QCL-TpyeD reference signal associated with a channel measurement resource associated with which aperiodic CSI reports in an aperiodic CSI report configured by a network, and then the same aperiodic CSI report is used as a target aperiodic CSI report to be triggered, so that an (implicittrigger) aperiodic CSI report is implicitly triggered by using the first DCI and configuration information configured by the network for CSI (the configuration information has each association relationship described above), which is further beneficial to reducing system resource overhead, improving system resource utilization rate, and ensuring high system deployment flexibility.

Case 2:

in one 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 in the TCI state indicated by the first DCI.

It should be noted that, based on the same principle, the TCI field in the DCI may indicate the TCI status from the activated TCI status activated by the network, and the indicated TCI status may give 1 or 2 QCL type parameters (e.g., QCL-type reference signal). In addition, because the QCL-type reference signal associated with the channel measurement resource associated with the aperiodic CSI report configured by the network is also associated with the QCL-type reference signal, the embodiment of the present application determines, by determining which of the QCL-type reference signals associated with the channel measurement resource associated with the aperiodic CSI report in the aperiodic CSI report configured by the network device are the same as the QCL-type reference signal in the TCI state indicated by the TCI field in the first DCI sent by the network device, and then triggers the aperiodic CSI report as the target aperiodic CSI report, thereby implementing to implicitly trigger the aperiodic CSI report by using the first DCI and the configuration information configured by the network for the CSI, which is further beneficial to reducing the system signaling overhead, improving the system resource utilization rate, and ensuring high flexibility of system deployment.

Case 3:

in one 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.

It should be noted that, based on the same principle as above, since the QCL-TypeD reference signal in the TCI state indicated by the first DCI is also related to the QCL-TypeD reference signal, therefore, in the embodiment of the present application, by determining that the QCL-type reference signal associated with the QCL-type 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-type reference signal associated with the channel measurement resource associated with which aperiodic CSI report is associated in the aperiodic CSI reports configured by the network, the same aperiodic CSI report is used as the target aperiodic CSI report to trigger, thereby enabling to implicitly trigger aperiodic CSI reporting through the first DCI and configuration information configured by the network for CSI, therefore, the method is beneficial to reducing the signaling overhead of the system, improving the utilization rate of system resources and ensuring high flexibility of system deployment.

Case 4:

It should be noted that, based on the above same principle, it can be seen that, in the embodiment of the present application, by determining that a QCL-type reference signal associated with a QCL-type reference signal in a TCI state indicated by a TCI field in a first DCI sent by a network device is the same as a QCL-type reference signal associated with a channel measurement resource associated with which aperiodic CSI report is configured in an aperiodic CSI report configured by the network, and then using the same aperiodic CSI report as a target aperiodic CSI report to trigger, the aperiodic CSI report is implicitly triggered by using the first DCI and the configuration information configured by the network for CSI, thereby facilitating reduction of system signaling overhead, improvement of system resource utilization, and guarantee of high flexibility in system deployment.

Case 5:

in one 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 the 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.

It should be noted that, as known from the descriptions in the "channel state information", "CSI report", "quasi-co-location", and "antenna port quasi-co-location", the network device may activate the TCI state to the terminal through an activation command (e.g., MAC CE), and then indicate the TCI state from the activated TCI state by the TCI field in the delivered DCI. Therefore, in the embodiment of the present application, by first determining that at least one of the QCL-type reference signals in the activated TCI states, except the QCL-type reference signal in the TCI state indicated by the TCI field in the first DCI and/or the QCL-type reference signal associated with the QCL-type reference signal in the TCI state indicated by the TCI field in the first DCI, is the same as the QCL-type reference signal associated with the channel measurement resource associated with which aperiodic CSI report in the aperiodic CSI report configured by the network is activated, and then using the same aperiodic CSI report as the target aperiodic CSI report to trigger, thereby enabling to implicitly trigger aperiodic CSI reporting through the first DCI and configuration information configured by the network for CSI, therefore, the method is beneficial to reducing the signaling overhead of the system, improving the utilization rate of system resources and ensuring high flexibility of system deployment.

Case 6:

in one possible example, the synchronization signal block SSB associated with the QCL type D reference signal associated with the channel measurement resource associated with the target aperiodic CSI report satisfies a correlation threshold with the SSB associated with the QCL type D reference signal in the TCI state indicated by the first DCI.

Wherein the correlation threshold is configured or preconfigured by the network.

It should be noted that, based on the above-mentioned similar reasoning, since the QCL-type D reference signal is also associated to the SSB, the embodiment of the present application first determines, by determining which SSBs associated with the QCL-type D reference signal associated with the channel measurement resource associated with the aperiodic CSI report in the aperiodic CSI report configured by the network device and the SSBs 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 satisfy the correlation threshold. Where a correlation threshold is met, it is indicated that there is a higher correlation (e.g., above the correlation threshold) or a lower correlation (e.g., below the correlation threshold). And then, triggering the aperiodic CSI report meeting the correlation threshold as a target aperiodic CSI report, so that the aperiodic CSI report is implicitly triggered through the first DCI and the configuration information configured by the network for the CSI, thereby being beneficial to reducing the signaling overhead of the system, improving the utilization rate of system resources and ensuring high flexibility of system deployment.

In order to integrate the above descriptions of various situations in which a target aperiodic CSI report exists, in researching the triggering problem of the aperiodic CSI report, a person skilled in the art can think that the network has configured 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 configuration information for CSI configured in advance. That is, before S210, the terminal acquires the configuration information for CSI from the network device, which is not described in detail herein.

With reference to the foregoing description, the following description further illustrates resources for carrying a target aperiodic CSI report in an embodiment of the present application.

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

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

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

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

In conjunction with the above description, the following embodiments of the present application will specifically describe how to determine the trigger status of the aperiodic CSI report for network configuration according to the first DCI.

The first method is as follows:

in one possible example, determining a trigger state for aperiodic channel state information, CSI, reporting configured for the network according to the first DCI may include: and the terminal determines a trigger state according to the beam type indicated by the first DCI.

Wherein the beam type indicated by the first DCI includes at least one of a downlink beam, an uplink beam, a downlink common beam, and an uplink common beam.

It should be noted that the terminal determines the trigger state according to the beam type indicated by the first DCI, which may also be understood as that the terminal determines whether an aperiodic CSI report is triggered in the aperiodic CSI reports configured by the network according to the beam type indicated by the first DCI. As can be seen, in the embodiment of the present application, the trigger state of the aperiodic CSI report configured for the network is determined according to the beam type indicated by the first DCI, so that a processing mechanism for the aperiodic CSI is implemented through the trigger state (that is, whether the aperiodic CSI report is triggered in the aperiodic CSI report configured for the network) 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.

Specifically, determining the trigger 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 an aperiodic CSI report is triggered in the aperiodic CSI report with the triggering state configured by the network; or, if the beam type indicated by the first DCI is an uplink beam, the terminal determines that the aperiodic CSI report is not triggered in the aperiodic CSI report whose trigger state is configured by the network.

It should be noted that, the terminal generally performs channel measurement through a reference signal (such as CSI-RS) transmitted through a downlink and then reports the channel measurement, so that if the first DCI indicates a downlink beam and the beam may be characterized by a QCL-type reference signal, there may be a case where measurement for the reference signal and aperiodic CSI report are triggered; if the first DCI indicates an uplink beam, there may be no aperiodic CSI report trigger since uplink channel measurement reporting is not required.

The second method comprises the following steps:

in one possible example, determining a trigger state for aperiodic channel state information, CSI, reporting configured for a network according to a first DCI may include: and the terminal determines the trigger state according to the QCL type D reference signal in the TCI state indicated by the first DCI.

It should be noted that, based on the above similar reasoning, 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 aperiodic CSI report configured by the network, in the embodiment of the present application, the trigger state is determined by the QCL type D reference signal in the TCI state indicated by the first DCI, so that a processing mechanism for the aperiodic channel state information is implemented by the trigger state (that is, which aperiodic CSI reports are triggered in the aperiodic CSI report configured by the network), and then the aperiodic CSI report is implicitly triggered, so as to facilitate reducing system signaling overhead, improve system resource utilization, and ensure high system deployment flexibility.

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 transmission configuration indicated by the first DCI indicates that the QCL type D reference signal in the TCI state 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 aperiodic CSI reports configured by the network, the terminal determines that the trigger state is that the at least one target aperiodic CSI report is triggered.

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 aperiodic CSI reports configured by the network, the terminal determines that the trigger state is that the at least one target aperiodic CSI report is triggered.

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 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 aperiodic CSI reports configured by the network, the terminal determines that the trigger state is that the at least one target aperiodic CSI report is triggered.

The third method comprises the following steps:

in one possible example, determining a trigger state for aperiodic channel state information, CSI, reporting configured for the network according to the first DCI may include: the terminal determines the trigger state according to QCL type D reference signals in other activated TCI states except for the QCL type D reference signals in the TCI state indicated by the first DCI and/or QCL type D reference signals associated with the QCL type D reference signals in the TCI state indicated by the first DCI.

It should be noted that, based on the above-mentioned similar reasoning, since QCL type D reference signals in other activated 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 resource associated with the aperiodic CSI report configured by the network, in the embodiment of the present application, the trigger state is determined by the QCL type D reference signals 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, so that a processing mechanism for the aperiodic channel state information (that what is included in the aperiodic CSI report configured by the network) is implemented by the trigger state The aperiodic CSI report is triggered), and then the aperiodic CSI report is implicitly triggered, so as to facilitate reducing the system signaling overhead, improve the utilization rate of the system resources, and ensure high flexibility of system deployment.

Specifically, determining the trigger state according to the QCL type D reference signals in the activated TCI state 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 may include: if the QCL type D reference signals in the activated TCI states except the QCL type D reference signals in the TCI states indicated by the first DCI and/or the QCL type D reference signals associated with the QCL type D reference signals in the TCI states indicated by the first DCI are 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 aperiodic CSI reports configured by the network, the terminal determines that the trigger state is that the at least one target aperiodic CSI report is triggered.

The method is as follows:

in one possible example, determining a trigger state for aperiodic channel state information, CSI, reporting configured for the network according to the first DCI may include: and the terminal determines the trigger state according to the SSB associated with the QCL type D reference signal in the TCI state indicated by the first DCI.

It should be noted that, based on the above similar reasoning, 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 resource associated with the aperiodic CSI report configured by the network, in the embodiment of the present application, the trigger state is determined by the SSB associated with the QCL type D reference signal in the TCI state indicated by the first DCI, so that the processing mechanism for the aperiodic channel state information is implemented by the trigger state (that is, which aperiodic CSI reports are triggered in the aperiodic CSI report configured by the network), and then the aperiodic CSI report is implicitly triggered, so as to facilitate reducing system signaling overhead, improve system resource utilization rate, and ensure high system deployment flexibility.

Specifically, determining the trigger state according to 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 and the SSB associated with the QCL type D reference signal associated with the channel measurement resource associated with at least one target aperiodic CSI report in the aperiodic CSI reports configured by the network satisfy a correlation threshold, the terminal determines that the trigger state is that the at least one target aperiodic CSI report is triggered.

It can be seen that, in this embodiment of the present application, first, the network device sends the first DCI to the terminal. Then, the terminal acquires the first DCI from the network equipment, and determines a trigger state of the aperiodic CSI report configured for the network according to the first DCI. Finally, the trigger state is used for indicating whether an aperiodic CSI report is triggered in the aperiodic CSI reports configured by the network and/or at least one target aperiodic CSI report is triggered in the aperiodic CSI reports configured by the network, so that a processing mechanism for aperiodic channel state information (i.e., whether an aperiodic CSI report is triggered and/or which aperiodic CSI reports are triggered in the aperiodic CSI reports configured by the network) is implemented by the trigger state determined by the first DCI, thereby implementing implicit triggering of the aperiodic CSI reports, which is beneficial to reducing system signaling overhead, improving system resource utilization and ensuring high system deployment flexibility.

The above description has mainly described the solution of the embodiments of the present application from the perspective of the method side. It is understood that the terminal or the network device includes a hardware structure and/or a software module for performing the respective functions in order to implement the above functions. Those of skill in the art will readily appreciate that the various illustrative elements and algorithm steps described in connection with the embodiments disclosed herein may be implemented as hardware or combinations of hardware and computer software. Whether a function is performed in hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

The embodiment of the application can perform functional unit division on the terminal or the network device according to the method example. For example, each functional unit may be divided for each function, or two or more functions may be integrated into one processing unit. The integrated unit may be implemented in the form of hardware, or may be implemented in the form of a software program module. It should be noted that, in the embodiment of the present application, the division of the unit is schematic, and is only one division of a logic function, and another division may be used in actual implementation.

In the case of integrated units, fig. 3 provides a block diagram of the functional units of an apparatus for aperiodic channel state information reporting. The apparatus 300 for aperiodic channel state information reporting comprises: a processing unit 302 and a communication unit 303. The processing unit 302 is used for controlling and managing the actions of the terminal. For example, the processing unit 302 is used to support the terminal to perform the steps in fig. 2 and other processes for the solution described in the present 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 comprise a storage unit 301 for storing program codes executed by the apparatus 300 for aperiodic channel state information reporting and transmitted data.

It should be noted that the apparatus 300 for aperiodic csi reporting may be a chip or a chip module.

The processing unit 302 may be a processor or a controller, and may be, for example, 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 device, a transistor logic device, a hardware component, or any combination thereof. Which may implement or perform the various illustrative logical blocks, modules, and circuits described in connection with the disclosure. The processing unit 302 may also be a combination that performs computing functions, e.g., including one or more microprocessors, a combination of DSPs and microprocessors, and the like. The communication unit 303 may be a communication interface, a transceiver, a transceiving 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 csi reporting according to this embodiment of the present application may be a terminal as shown in fig. 5.

In a specific implementation, the processing unit 302 is configured to perform any step performed by the terminal in the above method embodiment, and when performing data transmission such as sending, the communication unit 303 is optionally invoked to complete the corresponding operation. The details will be described below.

The processing unit 302 is configured to: acquiring first Downlink Control Information (DCI) from network equipment; determining a trigger state of aperiodic CSI reports for the network configuration according to the first DCI, wherein the trigger state is used for indicating whether aperiodic CSI reports of the network configuration are triggered and/or at least one target aperiodic CSI report of the aperiodic CSI reports of the network configuration is triggered.

It should be noted that specific implementation of each operation in the embodiment shown in fig. 3 may be detailed in the description of the method embodiment shown in fig. 2, and details are not described herein again.

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

In one possible example, the first DCI does not include a CSI request field.

In one possible example, the first DCI is used to indicate at least one of a downlink beam, an uplink beam, a downlink common beam, and an uplink common beam.

In one possible example, the trigger state includes at least one of: at least one target aperiodic CSI report in the aperiodic CSI reports configured by the network is triggered, no aperiodic CSI report in the aperiodic CSI reports configured by the network is triggered, and the aperiodic CSI reports configured by the network is triggered.

In one possible example, the quasi-co-located 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 in the transmission configuration indication TCI state indicated by the first DCI; or, a QCL type D reference signal associated with a channel measurement resource 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; or, a QCL type D reference signal associated with a 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; or, a QCL type D reference signal associated with a channel measurement resource associated with a target aperiodic CSI report is the same as a QCL type D reference signal associated with a QCL type D reference signal in a TCI state indicated by the first DCI.

In one possible example, the correlation threshold is configured or preconfigured by the network.

In one possible example, if the first DCI is a DCI for downlink scheduling, the target aperiodic CSI report is carried by a physical uplink control channel resource indicated by the first DCI; or, if the first DCI is a DCI for uplink scheduling, the target aperiodic CSI report is carried by a physical uplink shared channel resource, and the physical uplink shared channel resource is determined by frequency domain resource indication information and configuration information of the CSI report in the first DCI.

In one possible example, in terms of determining a trigger state for aperiodic channel state information, CSI, report configured by the network according to the first DCI, the processing unit 302 is specifically configured to: and determining a trigger state according to the beam type indicated by the first DCI.

Which may implement or perform the various illustrative logical blocks, modules, and circuits described in connection with the disclosure. Processing unit 402 may also be a combination that performs computing functions, e.g., comprising one or more microprocessors, a combination of DSPs and microprocessors, and the like.
