Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of UEs 11 and a plurality of network devices 12.

The wireless communication system may be a 4th generation mobile communication (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system.

Alternatively, an MTC system.

Among them, UE 11 can be a device that provides voice and/or data connectivity to users. UE 11 can communicate with one or more core networks via a radio access network (RAN). UE 11 can be an Internet of Things UE, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an Internet of Things UE, for example, a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote UE (remote terminal), an access UE (access terminal), a user terminal, a user agent, a user device, or a user UE (user equipment, UE).

Alternatively, UE 11 may be an onboard device, for example, a driving computer with a wireless communication function, or a wireless communication device external to the driving computer. Alternatively, UE 11 may be a roadside device, for example, a street lamp, a signal lamp, or other roadside device with a wireless communication function.

The network device 12 may include an access network device. Optionally, the network device 12 may also include a core network device. Among them, the access network device may be an evolved access device (eNB) adopted in a 4G system. Alternatively, it may also be an access device (gNB) adopting a centralized distributed architecture in a 5G system. When the access network device adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer protocol stack; the distributed unit is provided with a physical (PHY) layer protocol stack. The specific implementation method of the access network device is not limited in the embodiments of the present disclosure.

A wireless connection can be established between the network device 12 and the UE 11 through a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

In some examples, the access device 12 may be an access device of a terrestrial network (TN), or may be an NTN device having all or part of the functions of an access network.

Among them, the AMF, UPF, PCF, etc. in the embodiments of the present disclosure may be implemented by one physical device or by multiple physical devices. It is understandable that the AMF, UPF, PCF, etc. in the embodiments of the present disclosure may be a logical function module in a physical device or a logical function module composed of multiple physical devices, which is not limited in the embodiments of the present disclosure.

It should be noted that the network architecture shown in FIG. 1 is only an example applicable to the embodiment of the present disclosure and does not constitute a limitation on the scope of application of the embodiment of the present disclosure.

In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed separately, or can be executed together with the methods of other embodiments of the embodiments of the present disclosure, or can be executed together with some methods in other related technologies separately or in combination; the embodiments of the present disclosure do not limit this.

The maximum number of receive beams (maxNumberRxBeam) supported by the UE when using CSI-RS resources, that is, the receive beam scanning capability, where the receive beam scanning capability is the number of CSI-RS resources (NZP CSI-RS) repetitions for each CSI-RS resource set. That is, the number of receive beams that the UE needs to scan for each NZP CSI-RS resource. On a CSI-RS resource set, the number of receive beams that can be used for each CSI-RS resource is N = ceil (maxNumberRxBeam/Nres_per_set), where ceil() means rounding up. Among them, Nres_per_set is the number of CSI-RS resources in the CSI-RS resource set. In the CSI-RS measurement and transmission of FR2UE, the UE can perform periodic and semi-static periodic CSI-RS measurement and transmission, and the UE has only one antenna panel (panel) for receive beam scanning. Therefore, the UE only transmits the receiving beam scanning capability supported by the UE on one frequency band. Mobile communication technology introduces the concept of multi-transmission and receiving point (mTRP), that is, multi-TRP transmission, and introduces two control methods of S-DCI and M-DCI. For multiple TRPs, the UE can configure multiple antenna panels to achieve simultaneous transmission in multiple directions. Similarly, for two TRPs, when the network configures NZP CSI-RS resources, it will also configure two NZP CSI-RS resource sets.

In some embodiments of the present disclosure, the UE's receive beam scanning capability may be different for each CSI-RS resource set. If the UE sends only one receive beam scanning capability, in this case, the network device cannot determine the CSI-R resource set corresponding to the receive beam scanning capability sent by the UE, and will misjudge the corresponding receive beam scanning capability as applicable to all CSI-RS resource sets, such as misjudging the receive beam scanning capability as applicable to the CSI-RS resource set 2 being used, which will cause the network device to make an incorrect judgment on the UE's receive beam scanning capability.

Therefore, as shown in FIG. 2 to FIG. 13 , the embodiments of the present disclosure provide an information transmission method, which can enable a network device to determine the receiving beam scanning capability of a UE.

As shown in FIG. 2 , an embodiment of the present disclosure provides an information transmission method, which is executed by a UE and includes:

Step 201: Determine that there are multiple CSI-RS resource sets, and the multiple CSI-RS resource sets are associated with multiple TRPs of a network device, and send capability information to the network device, wherein the capability information is used to indicate the receiving beam scanning capability of the UE corresponding to at least one of the CSI-RS resource sets, and the receiving beam scanning capability is used to indicate: the number of receiving beams scanned by the UE for a CSI-RS resource in the CSI-RS resource set.

In one possible implementation, the UE may determine that the network device uses multiple TRPs to send signals based on indication information sent by the network device to the UE.

In one possible implementation, the UE may determine, based on the provisions of the communication protocol, that the network device uses multiple TRPs to send signals.

The multiple CSI-RS resource sets are associated with multiple sending and receiving points TRP of the network device, and the network device may use multiple TRPs to send CSI-RS based on multiple CSI-RS resource sets.

In one possible implementation, the network device may use multiple TRPs to send CSI-RS based on the CSI-RS resource sets corresponding to each TRP at the same time, where one TRP may correspond to one CSI-RS resource set.

In a possible implementation, the network device may send multiple CSI-RS resource sets to the UE. The UE may determine the number of CSI-RS resource sets according to the received CSI-RS resource sets.

The UE may confirm the receiving beam scanning capability of the UE for each CSI-RS resource set, which may include: the number of receiving beams that the UE needs to scan for a CSI-RS resource in the CSI-RS resource set; that is, the number of repetitions of the UE for a CSI-RS resource in the CSI-RS resource set; that is, the number of receiving beam scans performed by the UE for a CSI-RS resource in the CSI-RS resource set;

In this way, the UE sends the receiving beam scanning capability determined for each CSI-RS resource set to the network device through capability information, thereby improving the accuracy of the network device in determining the UE's receiving beam scanning capability, reducing the network device's misjudgment of the UE's receiving beam scanning capability, and reducing resource configuration errors caused by the network device's misjudgment of the UE's receiving beam scanning capability.

As shown in FIG3 , an embodiment of the present disclosure provides an information transmission method, which is executed by a UE and includes:

Step 301: According to each of the CSI-RS resource sets, determine the receiving beam scanning capability corresponding to each of the CSI-RS resource sets.

For different CSI-RS resource sets, the receiving beam scanning capabilities adopted by the UE may be different due to the different parameters such as the configured transmission resources. Therefore, the UE may respectively determine the receiving beam scanning capabilities corresponding to different CSI-RS resource sets, for example, determining the receiving beam scanning capability corresponding to CSI-RS resource set 1 as capability 1, and determining the receiving beam scanning capability corresponding to CSI-RS resource set 2 as capability 2. For different CSI-RS resource sets, the receiving beam scanning capabilities determined by the UE may be the same or different.

Exemplarily, the network device may use two TRPs to respectively use one CSI-RS resource set to send CSI-RS. The UE uses different receiving beam scanning capabilities to receive CSI-RS for different CSI-RS resource sets.

In the related art, the UE does not determine the receive beam scanning capability based on the CSI-RS resource set. The UE uses the same receive beam scanning capability for different CSI-RS resource sets. For example, the UE determines that the receive beam scanning capability corresponding to all CSI-RS resource sets is capability 1, so that the receive beam scanning capability does not match the CSI-RS resource set.

The UE may determine corresponding receiving beam scanning capabilities for different CSI-RS resource sets, and send capability information to the network device to indicate the receiving beam scanning capability for at least one CSI-RS resource set.

For example, the capability information may indicate the receiving beam scanning capability of the UE for each CSI-RS resource set. The network device may determine the receiving beam scanning capability of the UE for each CSI-RS resource set, thereby determining the duration required for the UE to perform CSI-RS measurement, etc.

For example, the capability information includes first information and second information corresponding to the first information, the first information is used to identify CSI-RS resource set 1, and the second information is used to indicate the receiving beam scanning capability 1 of the CSI-RS resource set 1.

As shown in FIG. 4 , an embodiment of the present disclosure provides an information transmission method, which is executed by a UE and includes:

Step 401: Receive indication information sent by the network device, wherein the indication information is used to determine the number of the CSI-RS resource sets.

The network device may send the number of the configured CSI-RS resource sets to the UE via indication information.

The UE may determine the number of CSI-RS resource sets according to the indication information sent by the network device, and determine the receiving beam scanning capability for each CSI-RS resource set.

The indication information may indicate the number of CSI-RS resource sets. Alternatively, the indication information may indicate multiple CSI-RS resource sets, and the UE determines the number of CSI-RS resource sets according to the received CSI-RS resource sets. For example, the indication information may be PDSCH-Config.

Exemplarily, the network device may send CSI-ReportConfig to the UE. If the UE determines to configure groupBasedBeamReporting-r17 in CSI-ReportConfig, and the nzp-CSI-RS-ResourceSetList configured in the CSI-ResourceConfig information element (IE) is a CSI-RS resource set greater than 1, then after receiving the CSI-RS resource set configuration of nzp, the UE determines the receive beam scanning capability maxNumberRxBeamSeti of the CSI-RS resources that it can support on the i-th CSI-RS resource set, and sends the receive beam scanning capabilities corresponding to all CSI-RS resource sets.

In one embodiment, the receiving beam scanning capability is at least used for the network device to determine the measurement duration required for the UE to perform CSI-RS measurement on a CSI-RS resource, wherein the CSI-RS resource set corresponding to the receiving beam scanning capability includes at least one of the CSI-RS resources.

A CSI-RS resource set may include one or more CSI-RS resources.

In a possible implementation, the receive beam scanning capability may be at the granularity of a CSI-RS resource set, that is, a CSI-RS resource set may correspond to a receive beam scanning capability, and any CSI-RS resource in the CSI-RS resource set corresponds to the receive beam scanning capability.

The network device sends the CSI-RS in the CSI-RS resource. The network device needs to determine the duration for the UE to perform CSI-RS measurement on a CSI-RS resource, and then configure subsequent resources for the UE.

The receive beam scanning capability corresponding to the CSI-RS resource set can be applied to any CSI-RS resource in the CSI-RS resource set. Therefore, the receive beam scanning capability can represent the number of receive beam scans N performed by the UE on a CSI-RS resource in the CSI-RS resource set. That is, the terminal needs to perform maxNumberRxBeamSeti beam scans before it can perform a complete receive beam scan on a CSI-RS resource in the CSI-RS resource set and obtain the measurement value of the CSI-RS transmitted through the CSI-RS resource. maxNumberRxBeamSeti is the receive beam scanning capability.

The network device determines the receive beam scanning capability, that is, determines the number of receive beam scans N performed by the UE on a CSI-RS resource in the CSI-RS resource set, in order to determine the duration of the UE's CSI-RS measurement on a CSI-RS resource.

In one embodiment, the measurement duration is determined based on the receive beam scanning capability and a single-wave measurement duration required for the UE to perform the CSI-RS measurement in a receive beam.

The single-wave measurement duration required for the UE to perform the CSI-RS measurement in one receiving beam may be the duration for the UE to perform a receiving beam scan, that is, the duration for scanning using one receiving beam.

The network device can determine the duration of the UE's CSI-RS measurement for a CSI-RS resource based at least on the number N of receive beam scans performed by the UE on a CSI-RS resource in the CSI-RS resource set and the duration of one receive beam scan.

Exemplarily, the receive beam scanning capability corresponding to the CSI-RS resource set can be applicable to any CSI-RS resource in the CSI-RS resource set. For the i-th CSI-RS resource set among multiple CSI-RS resource sets, the receive beam scanning capability maxNumberRxBeamSeti takes a value between [1,8]. The meaning of this value is that the terminal needs to perform maxNumberRxBeamSeti beam scans before it can perform a complete receive beam scan on a CSI-RS resource in the i-th CSI-RS resource set to obtain an accurate L1-RSRP measurement value. For the L1-RSRP measurement time based on the configured one beam scan, that is, the single-wave measurement duration Tmeasure, the actual time required for the terminal to complete a CSI-RS resource measurement is: Ttotal = Tmeasure*maxNumberRxBeamSeti.

In one embodiment, the single-wave measurement duration is determined based on the manner in which the UE performs the CSI-RS measurement and/or the measurement period of the CSI-RS.

Here, the manner in which the UE performs the CSI-RS measurement corresponds to different measurement durations. The manner in which the CSI-RS is measured includes but is not limited to the frequency domain position used for the CSI-RS measurement, for example, in-band measurement or out-of-band measurement.

The CSI-RS measurement period is associated with the interval at which the UE performs CSI-RS measurement.

In one embodiment, the time domain resources included in the multiple CSI-RS resource sets overlap;

The method further includes: performing CSI-RS measurement based on a plurality of the CSI-RS resource sets on the overlapping time domain resources.

The time domain resources included in the CSI-RS resource set may overlap. The network side device may send CSI-RS based on multiple CSI-RS resource sets at the same time.

In one possible implementation, the network device may use multiple TRPs to send CSI-RS, with one TRP sending CSI-RS based on a CSI-RS resource set. In this way, multiple TRPs may send CSI-RS corresponding to multiple CSI-RS resource sets on overlapping time domain resources.

The UE can measure the CSI-RS sent by multiple TRPs separately on overlapping time domain resources.

In one possible implementation, the UE may measure CSI-RS in multiple receive beam directions simultaneously, where one receive beam may correspond to a CSI-RS transmitted by a TRP.

For example, the network device has two TRPs, each TRP sends CSI-RS on overlapping time domain resources based on a CSI-RS resource set. The UE uses two beams at the same time to measure the CSI-RS sent by each TRP.

As shown in FIG5 , an embodiment of the present disclosure provides an information transmission method, which is executed by a UE and includes:

Step 501: Measure the CRI-RS respectively sent by the network device using multiple TRPs, wherein each of the TRPs corresponds to one of the multiple CSI-RS resource sets.

In a possible implementation, each of N TRPs may transmit CSI-RS based on one CSI-RS resource set, that is, N TRPs may correspond to N CSI-RS resource sets.

Exemplarily, the network device may have two TRPs, and the two TRPs may simultaneously send CSI-RS based on one CSI-RS resource set.

The UE can measure the CSI-RS sent by two TRPs at the same time.

In a possible implementation, the UE may implement receive beam scanning in multiple directions based on multiple antenna panels.

In a possible implementation, the UE may implement receive beam scanning in multiple directions based on one antenna panel.

In one embodiment, the measuring the CRI-RS sent by the network device using a plurality of the TRPs respectively based on one CSI-RS resource set includes:

Based on the receive beam scanning capability, the CRI-RS sent by the network device is measured.

In one possible implementation, for one CSI-RS resource set among multiple CSI-RS resource sets, the network side device may send CSI-RS based on the CSI-RS resources in the CSI-RS resource set. The UE may perform beam scanning based on the receiving beam scanning capability corresponding to the CSI-RS resource set.

For example, the receiving beam scanning capability corresponding to the CSI-RS resource set is to perform M receiving beam scans. Then when the network side device sends CSI-RS based on the CSI-RS resources in the CSI-RS resource set, the UE performs M receiving beam scans, that is, measures the CSI-RS on M receiving beams.

In one possible implementation, if the network device uses N TRPs to send CSI-RS at the same time, the UE can scan N receive beams at the same time, that is, the UE can measure the CSI-RS on N receive beams at the same time. Here, the N receive beams can be implemented by one or more antennas of the UE through beamforming. Here, each TRP can send CSI-RS based on the CSI-RS resources of a CSI-RS resource set, and the UE can use different receive beams to measure the CSI-RS associated with different CSI-RS resource sets at the same time.

As shown in FIG6 , an embodiment of the present disclosure provides an information transmission method, which is executed by a network device and includes:

Step 601: Receive capability information sent by the UE, wherein the capability information is used to indicate the receiving beam scanning capability of the UE corresponding to at least one CSI-RS resource set, wherein the capability information is determined when the UE determines that there are multiple channel state information reference signal CSI-RS resource sets, and the multiple CSI-RS resource sets are associated with multiple transmitting and receiving points TRP of a network device, and the receiving beam scanning capability is used to indicate: the number of receiving beams scanned by the UE for a CSI-RS resource in the CSI-RS resource set.

In one possible implementation, the network device sends indication information, and the UE can determine that the network device uses multiple TRPs to send signals based on the indication information sent by the network device to the UE.

The multiple CSI-RS resource sets are associated with multiple transmitting and receiving points TRP of the network device, and the network device can use multiple TRPs to send CSI-RS based on multiple CSI-RS resource sets.

In one possible implementation, the network device may use multiple TRPs to send CSI-RS based on the CSI-RS resource sets corresponding to each TRP at the same time, where one TRP may correspond to one CSI-RS resource set.

In a possible implementation, the network device may send multiple CSI-RS resource sets to the UE. The UE may determine the number of CSI-RS resource sets according to the received CSI-RS resource sets.

The UE may confirm the receiving beam scanning capability of the UE for each CSI-RS resource set, which may include: the number of receiving beams that the UE needs to scan for a CSI-RS resource in the CSI-RS resource set; that is, the number of repetitions of the UE for a CSI-RS resource in the CSI-RS resource set; that is, the number of receiving beam scans performed by the UE for a CSI-RS resource in the CSI-RS resource set;

In this way, the network device determines the receiving beam scanning capability of the UE for each CSI-RS resource set based on the capability information, thereby improving the accuracy of the network device in determining the receiving beam scanning capability of the UE, reducing the network device's misjudgment of the UE's receiving beam scanning capability, and reducing resource configuration errors caused by the network device's misjudgment of the UE's receiving beam scanning capability.

In one embodiment, the receiving beam scanning capability corresponding to each of the CSI-RS resource sets is determined by the UE separately according to each of the CSI-RS resource sets.

For different CSI-RS resource sets, the receiving beam scanning capabilities adopted by the UE may be different due to the different parameters such as the configured transmission resources. Therefore, the UE may determine the receiving beam scanning capabilities corresponding to different CSI-RS resource sets respectively, for example, determining the receiving beam scanning capability corresponding to resource 1 as capability 1, and determining the receiving beam scanning capability corresponding to resource 2 as capability 2. For different CSI-RS resource sets, the receiving beam scanning capabilities determined by the UE may be the same or different.

Exemplarily, the network device may use two TRPs to respectively use one CSI-RS resource set to send CSI-RS. The UE uses different receiving beam scanning capabilities to receive CSI-RS for different CSI-RS resource sets.

In the related art, the UE does not determine the receive beam scanning capability based on the CSI-RS resource set. The UE uses the same receive beam scanning capability for different CSI-RS resource sets. For example, the UE determines that the receive beam scanning capability corresponding to all CSI-RS resource sets is capability 1, so that the receive beam scanning capability does not match the CSI-RS resource set.

The UE may determine corresponding receiving beam scanning capabilities for different CSI-RS resource sets, and send capability information to the network device to indicate the receiving beam scanning capability for at least one CSI-RS resource set.

For example, the capability information may indicate the receiving beam scanning capability of the UE for each CSI-RS resource set. The network device may determine the receiving beam scanning capability of the UE for each CSI-RS resource set, thereby determining the duration required for the UE to perform CSI-RS measurement, etc.

For example, the capability information includes first information and second information corresponding to the first information, the first information is used to identify CSI-RS resource set 1, and the second information is used to indicate the receiving beam scanning capability 1 of the CSI-RS resource set 1.

As shown in FIG. 7 , an embodiment of the present disclosure provides an information transmission method, which is executed by a network device and includes:

Step 701: Send indication information to the UE, wherein the indication information is used to determine the number of the CSI-RS resource sets.

The network device may send the number of the configured CSI-RS resource sets to the UE via indication information.

The UE may determine the number of CSI-RS resource sets according to the indication information sent by the network device, and determine the receiving beam scanning capability for each CSI-RS resource set.

The indication information may indicate the number of CSI-RS resource sets. Alternatively, the indication information may indicate multiple CSI-RS resource sets, and the UE determines the number of CSI-RS resource sets according to the received CSI-RS resource sets. For example, the indication information may be PDSCH-Config.

Exemplarily, the network device may send CSI-ReportConfig to the UE. If the UE determines to configure groupBasedBeamReporting-r17 in CSI-ReportConfig, and the nzp-CSI-RS-ResourceSetList configured in the CSI-ResourceConfig information element (IE) is a CSI-RS resource set greater than 1, then after receiving the CSI-RS resource set configuration of nzp, the UE determines the receive beam scanning capability maxNumberRxBeamSeti of the CSI-RS resources that it can support on the i-th CSI-RS resource set, and sends the receive beam scanning capabilities corresponding to all CSI-RS resource sets.

As shown in FIG8 , an embodiment of the present disclosure provides an information transmission method, which is executed by a network device and includes:

Step 801: Determine a measurement duration based on the receiving beam scanning capability of the UE, where the measurement duration is the measurement duration required for the UE to perform CSI-RS measurement on one CSI-RS resource, wherein the CSI-RS resource set corresponding to the receiving beam scanning capability includes at least one of the CSI-RS resources.

A CSI-RS resource set may include one or more CSI-RS resources.

In a possible implementation, the receive beam scanning capability may be at the granularity of a CSI-RS resource set, that is, a CSI-RS resource set may correspond to a receive beam scanning capability, and any CSI-RS resource in the CSI-RS resource set corresponds to the receive beam scanning capability.

The network device sends the CSI-RS in the CSI-RS resource. The network device needs to determine the duration for the UE to perform CSI-RS measurement on a CSI-RS resource, and then configure subsequent resources for the UE.

The receive beam scanning capability corresponding to the CSI-RS resource set can be applied to any CSI-RS resource in the CSI-RS resource set. Therefore, the receive beam scanning capability can represent the number of receive beam scans N performed by the UE on a CSI-RS resource in the CSI-RS resource set. That is, the terminal needs to perform maxNumberRxBeamSeti beam scans before it can perform a complete receive beam scan on a CSI-RS resource in the CSI-RS resource set and obtain the measurement value of the CSI-RS transmitted through the CSI-RS resource. maxNumberRxBeamSeti is the receive beam scanning capability.

The network device determines the receive beam scanning capability, that is, determines the number of receive beam scans N performed by the UE on a CSI-RS resource in the CSI-RS resource set, in order to determine the duration of the UE's CSI-RS measurement on a CSI-RS resource.

In one embodiment, the measurement duration is determined based on the receive beam scanning capability and a single-wave measurement duration required for the UE to perform the CSI-RS measurement in a receive beam.

The single-wave measurement duration required for the UE to perform the CSI-RS measurement in one receiving beam may be the duration for the UE to perform a receiving beam scan, that is, the duration for scanning using one receiving beam.

The network device can determine the duration of the UE's CSI-RS measurement for a CSI-RS resource based at least on the number N of receive beam scans performed by the UE on a CSI-RS resource in the CSI-RS resource set and the duration of one receive beam scan.

Exemplarily, the receive beam scanning capability corresponding to the CSI-RS resource set can be applicable to any CSI-RS resource in the CSI-RS resource set. For the i-th CSI-RS resource set among multiple CSI-RS resource sets, the receive beam scanning capability maxNumberRxBeamSeti takes a value between [1,8]. The meaning of this value is that the terminal needs to perform maxNumberRxBeamSeti beam scans before it can perform a complete receive beam scan on a CSI-RS resource in the i-th CSI-RS resource set to obtain an accurate L1-RSRP measurement value. For the L1-RSRP measurement time based on the configured one beam scan, that is, the single-wave measurement duration Tmeasure, the actual time required for the terminal to complete a CSI-RS resource measurement is: Ttotal = Tmeasure*maxNumberRxBeamSeti.

In one embodiment, the single-wave measurement duration is determined based on the manner in which the UE performs the CSI-RS measurement and/or the measurement period of the CSI-RS.

Here, the manner in which the UE performs the CSI-RS measurement corresponds to different measurement durations. The manner in which the CSI-RS is measured includes but is not limited to the frequency domain position used for the CSI-RS measurement, for example, in-band measurement or out-of-band measurement.

The CSI-RS measurement period is associated with the interval at which the UE performs CSI-RS measurement.

In one embodiment, the time domain resources included in the multiple CSI-RS resource sets overlap;

The method further includes sending a CSI-RS based on a plurality of the CSI-RS resources on the overlapping time domain resources.

The time domain resources included in the CSI-RS resource set may overlap. The network side device may send CSI-RS based on multiple CSI-RS resource sets at the same time.

In one possible implementation, the network device may use multiple TRPs to send CSI-RS, with one TRP sending CSI-RS based on a CSI-RS resource set. In this way, multiple TRPs may send CSI-RS corresponding to multiple CSI-RS resource sets on overlapping time domain resources.

The UE can measure the CSI-RS sent by multiple TRPs separately on overlapping time domain resources.

In one possible implementation, the UE may measure CSI-RS in multiple receive beam directions simultaneously, where one receive beam may correspond to a CSI-RS transmitted by a TRP.

For example, the network device has two TRPs, each TRP sends CSI-RS on overlapping time domain resources based on a CSI-RS resource set. The UE uses two beams at the same time to measure the CSI-RS sent by each TRP.

As shown in FIG9 , an embodiment of the present disclosure provides an information transmission method, which is executed by a network device and includes:

Step 901: Use multiple TRPs to send CRI-RS respectively, wherein each TRP corresponds to one of the multiple CSI-RS resource sets.

In a possible implementation, each of N TRPs may transmit CSI-RS based on one CSI-RS resource set, that is, N TRPs may correspond to N CSI-RS resource sets.

Exemplarily, the network device may have two TRPs, and the two TRPs may simultaneously send CSI-RS based on one CSI-RS resource set.

The UE can measure the CSI-RS sent by two TRPs at the same time.

In a possible implementation, the UE may implement receive beam scanning in multiple directions based on multiple antenna panels.

In a possible implementation, the UE may implement receive beam scanning in multiple directions based on one antenna panel.

Embodiment 1:

If groupBasedBeamReporting-r17 is configured in CSI-ReportConfig, and the nzp-CSI-RS-ResourceSetList configured in the CSI-ResourceConfig information element (IE) is a CSI-RS resource set greater than one, then after receiving the CSI-RS resource set configuration of nzp, the UE determines the receive beam scanning capability maxNumberRxBeamSeti of the CSI-RS resources that it can support on the i-th CSI-RS resource set, and sends the receive beam scanning capability corresponding to all CSI-RS resource sets. The network configures the UE's CSI-RS-based measurement time according to the receive beam scanning capability.

Embodiment 2:

For the i-th resource set, the value of maxNumberRxBeamSeti can be between [1,8]. The meaning of this value is that the UE needs to perform maxNumberRxBeamSeti beam scans before it can perform a complete receive beam scan on a CSI-RS resource and obtain an accurate L1-RSRP measurement value. For the L1-RSRP measurement time Tmeasure based on the configured 1-beam scan, the time required for the UE to complete the measurement for a CSI-RS resource is: Ttotal = Tmeasure*maxNumberRxBeamSeti.
