[0045] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11 and several network devices 12.

[0046] The wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be the next generation after 5G. In a 5G system, the access network can be called NG-RAN (New Generation-Radio Access Network) or an MTC system.

[0047] UE 11 can be a device that provides voice and / or data connectivity to a user. UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). UE 11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, UE 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0048] Network device 12 may include access network equipment. Optionally, network device 12 may also include core network equipment. The access network equipment may be an evolved NB (eNB) used in a 4G system, or a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access network equipment adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access network equipment.

[0049] Network device 12 and UE 11 can establish a wireless connection via 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, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0050] In some examples, access device 12 can be an access device for terrestrial networks (TN) or an NTN device with all or some of the functions of an access network.

[0051] NTN equipment can be, for example, satellites, high altitude platform systems (HAPS), or air-to-ground (ATG) equipment deployed in the NTN.

[0052] For example, access device 12 can be located in a communication system integrated with a satellite communication system and can provide connectivity services for satellites, enabling satellites to access the core network. For instance, access device 12 can be an access device with satellite gateway functionality in the communication system, such as a gateway device, ground station device, or non-terrestrial network gateway (NTN-Gateway).

[0053] For example, the wireless communication system described above may further include a core network device 13. A plurality of access devices 12 are respectively connected to the core network device 13. The core network device 13 may be an Access and Mobility Management Function (AMF), a User Plane Function (UPF), a Policy Control Function (PCF), etc. The implementation of the core network device 13 is not limited in this disclosure. In one example, the core network device 13 is a Sensing Function (SF) network element, where the SF is a functional network element that provides sensing services.

[0054] In this embodiment, AMF, UPF, PCF, etc., may be implemented by a single physical device or by multiple physical devices. It is understood that AMF, UPF, PCF, etc., in this embodiment may be a logical functional module within a physical device or a logical functional module composed of multiple physical devices; this embodiment does not impose any limitations on this.

[0055] It should be noted that, Figure 1 The network architecture shown is merely an example applicable to the embodiments of this disclosure and does not constitute a limitation on the scope of application of the embodiments of this disclosure.

[0056] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0057] The maximum number of receive beams (maxNumberRxBeam) that the UE supports when using CSI-RS resources, i.e., the receive beam scanning capability, is the number of repetitions of CSI-RS resources (NZP CSI-RS) for each CSI-RS resource set. In other words, it's the number of receive beams the UE needs to scan for each NZP CSI-RS resource. Within a CSI-RS resource set, the number of receive beams usable for each CSI-RS resource is N = ceil(maxNumberRxBeam / Nres_per_set), where ceil() represents rounding up. Nres_per_set is the number of CSI-RS resources in that CSI-RS resource set. In FR2 UE CSI-RS measurement and transmission, the UE can perform periodic and semi-static periodic CSI-RS measurement and transmission, and the UE only uses one antenna panel for receive beam scanning. Therefore, the UE only transmits within one frequency band, specifying the UE's supported receive beam scanning capability in that band. Mobile communication technology has introduced the concept of multi-transmission and receiving point (mTRP), which refers to multi-TRP transmission, and has introduced two control methods: 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, the network will also configure two NZP CSI-RS resource sets when configuring NZP CSI-RS resources.

[0058] In some embodiments disclosed herein, the UE's receive beam scanning capability may differ for each CSI-RS resource set. If the UE only transmits one receive beam scanning capability, the network device cannot determine the CSI-RS resource set corresponding to the received beam scanning capability transmitted by the UE. It may misjudge the corresponding receive beam scanning capability as applicable to all CSI-RS resource sets, such as misjudging that the receive beam scanning capability applies to the currently used CSI-RS resource set 2. This could lead to an error in the network device's judgment of the UE's receive beam scanning capability.

[0059] Therefore, as Figures 2 to 13 As shown, this disclosure provides an information transmission method that enables a network device to determine the receiving beam scanning capability of a UE.

[0060] like Figure 2 As shown, this disclosure provides an information transmission method, which is executed by a UE and includes:

[0061] Step 201: Determine that there are multiple CSI-RS resource sets, and that the multiple CSI-RS resource sets are associated with multiple TRPs of the network device, and send capability information to the network device, wherein the capability information is used to indicate the receive beam scanning capability of the UE for at least one of the CSI-RS resource sets respectively, and the receive beam scanning capability is used to indicate the number of receive beams that the UE scans for one CSI-RS resource in the CSI-RS resource set.

[0062] In one possible implementation, the UE can determine that the network device uses multiple TRPs for signal transmission based on the indication information sent to the UE by the network device.

[0063] In one possible implementation, the UE can determine, based on the provisions of the communication protocol, that the network device uses multiple TRPs for signal transmission.

[0064] Multiple CSI-RS resource sets are associated with multiple Transmit / Receive Points (TRPs) of the network device, which means that the network device can use multiple TRPs to send CSI-RS based on multiple CSI-RS resource sets.

[0065] In one possible implementation, network devices can use multiple TRPs to send CSI-RS based on the CSI-RS resource set corresponding to each TRP at the same time, wherein one TRP can correspond to one CSI-RS resource set.

[0066] In one possible implementation, the network device can send multiple CSI-RS resource sets to the UE. The UE can determine the number of CSI-RS resource sets based on the received CSI-RS resource sets.

[0067] The UE can confirm its receive beam scanning capability for each CSI-RS resource set, which may include: the number of receive 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 a CSI-RS resource in the CSI-RS resource set; that is, the number of times the UE performs receive beam scanning for a CSI-RS resource in the CSI-RS resource set.

[0068] In this way, the UE sends the receive beam scanning capability determined for each CSI-RS resource set to the network device through the capability information, which improves the accuracy of the network device in determining the UE's receive beam scanning capability, reduces the network device's misjudgment of the UE's receive beam scanning capability, and reduces resource configuration errors caused by the network device's misjudgment of the UE's receive beam scanning capability.

[0069] like Figure 3As shown, this disclosure provides an information transmission method, which is executed by a UE and includes:

[0070] Step 301: Determine the receiving beam scanning capability corresponding to each CSI-RS resource set based on each CSI-RS resource set.

[0071] For different CSI-RS resource sets, the receive beam scanning capability adopted by the UE can vary due to differences in parameters such as configured transmission resources. Therefore, the UE can determine the receive beam scanning capability corresponding to different CSI-RS resource sets. For example, the receive beam scanning capability corresponding to CSI-RS resource set 1 can be determined as capability 1, and the receive beam scanning capability corresponding to CSI-RS resource set 2 can be determined as capability 2. The receive beam scanning capability determined by the UE can be the same or different for different CSI-RS resource sets.

[0072] For example, a network device can transmit CSI-RS using two TRPs, each employing a CSI-RS resource set. The UE uses different receive beam scanning capabilities to receive CSI-RS for different CSI-RS resource sets.

[0073] In related technologies, the UE does not determine the receive beam scanning capability based on the CSI-RS resource set. Instead, 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, resulting in a mismatch between the receive beam scanning capability and the CSI-RS resource set.

[0074] The UE can determine the corresponding receive beam scanning capability for different CSI-RS resource sets and send capability information to the network device, indicating the receive beam scanning capability for at least one CSI-RS resource set.

[0075] For example, capability information can indicate the UE's receive beam scanning capability for each CSI-RS resource set. The network device can determine the UE's receive beam scanning capability for each CSI-RS resource set, thereby determining the time required for the UE to perform CSI-RS measurements, etc.

[0076] For example, 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 receive beam scanning capability 1 of the CSI-RS resource set 1.

[0077] like Figure 4 As shown, this disclosure provides an information transmission method, which is executed by a UE and includes:

[0078] Step 401: Receive indication information sent by the network device, wherein the indication information is used to determine the number of CSI-RS resource sets.

[0079] The network device can send the number of configured CSI-RS resource sets to the UE via indication information.

[0080] The UE can determine the number of CSI-RS resource sets based on the indication information sent by the network device, and determine the receive beam scanning capability for each CSI-RS resource set.

[0081] The indication information can indicate the number of CSI-RS resource sets. Alternatively, the indication information can indicate multiple CSI-RS resource sets, and the UE determines the number of CSI-RS resource sets based on the received CSI-RS resource sets. For example, the indication information can be PDSCH-Config.

[0082] For example, a network device can send CSI-ReportConfig to the UE. If the UE determines that it has configured 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 with more than one element, then after receiving the CSI-RS resource set configuration from 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.

[0083] In one embodiment, the receive beam scanning capability is at least used to enable the network device to determine the measurement duration required for the UE to perform a CSI-RS measurement for a CSI-RS resource, wherein the set of CSI-RS resources corresponding to the receive beam scanning capability includes at least one of the CSI-RS resources.

[0084] A CSI-RS resource set may include one or more CSI-RS resources.

[0085] In one possible implementation, the receive beam scanning capability can be at the CSI-RS resource set granularity. That is, a CSI-RS resource set can correspond to a receive beam scanning capability, and any CSI-RS resource in the CSI-RS resource set corresponds to that receive beam scanning capability.

[0086] Network devices transmit CSI-RS data in CSI-RS resources. The network device needs to determine the duration for which the UE performs CSI-RS measurements on a given CSI-RS resource in order to configure subsequent resources for the UE.

[0087] The receive beam scanning capability corresponding to a 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 be represented by the number N times the UE performs a receive beam scan on a CSI-RS resource in the CSI-RS resource set. That is, the terminal needs to perform maxNumberRxBeamSeti beam scans to complete a 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 that CSI-RS resource. maxNumberRxBeamSeti is the receive beam scanning capability.

[0088] The network device determines the receive beam scanning capability, that is, it determines the number of times N the UE performs receive beam scanning 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.

[0089] In one embodiment, the measurement duration is determined based on the receiving beam scanning capability and the single-wavelength measurement duration required for the UE to perform the CSI-RS measurement within a receiving beam.

[0090] The single-wave measurement duration required for the UE to perform the CSI-RS measurement within a receiving beam can be the duration of the UE performing one receiving beam scan, i.e., the duration of scanning using one receiving beam.

[0091] The network device can determine the duration of a CSI-RS measurement performed by the UE for a CSI-RS resource based at least on the number N of receive beam scans performed by the UE for a CSI-RS resource in the CSI-RS resource set, and the duration of one receive beam scan.

[0092] For example, the receive beam scanning capability corresponding to a CSI-RS resource set can be applied 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 the value between [1,8]. This value means 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 and obtain an accurate L1-RSRP measurement value. For the L1-RSRP measurement time based on the configured 1 beam scan, i.e., the single-wavelength measurement duration Tmeasure, the actual time required for the terminal to complete the measurement of a CSI-RS resource is: Ttotal = Tmeasure * maxNumberRxBeamSeti.

[0093] In one embodiment, the single-wavelength measurement duration is determined based on the method by which the UE performs the CSI-RS measurement and / or the measurement cycle of the CSI-RS.

[0094] Here, the method by which the UE performs the CSI-RS measurement corresponds to different measurement durations. The CSI-RS measurement method includes, but is not limited to, the frequency domain location used for the CSI-RS measurement, such as in-band measurement or out-of-band measurement.

[0095] The CSI-RS measurement period is related to the interval at which the UE performs CSI-RS measurements.

[0096] In one embodiment, the time-domain resources contained in the plurality of CSI-RS resource sets overlap;

[0097] The method further includes performing CSI-RS measurements on the overlapping time-domain resources based on multiple sets of CSI-RS resources.

[0098] The time-domain resources contained in a CSI-RS resource set can overlap. Network-side devices can simultaneously send CSI-RS based on multiple CSI-RS resource sets.

[0099] In one possible implementation, the network device can use multiple TRPs to send CSI-RS, with each TRP sending CSI-RS based on a CSI-RS resource set. In this way, multiple TRPs can send CSI-RS corresponding to multiple CSI-RS resource sets on overlapping time-domain resources.

[0100] The UE can measure CSI-RS transmitted by multiple TRPs on overlapping time-domain resources.

[0101] In one possible implementation, the UE can simultaneously measure CSI-RS in multiple receive beam directions, where one receive beam can correspond to the CSI-RS transmitted by a TRP.

[0102] For example, a network device has two Transmission Points (TRPs), each of which transmits CSI-RS on overlapping time-domain resources based on a CSI-RS resource set. The UE uses two beams simultaneously to measure the CSI-RS transmitted by one TRP.

[0103] like Figure 5 As shown, this disclosure provides an information transmission method, which is executed by a UE and includes:

[0104] Step 501: The network device is measured using CRI-RS sent by multiple TRPs, wherein each TRP corresponds to one of the multiple CSI-RS resource sets.

[0105] In one possible implementation, N TRPs can each send CSI-RS based on a CSI-RS resource set. That is, N TRPs can correspond to N CSI-RS resource sets.

[0106] For example, a network device may have two TRPs, and the two TRPs may simultaneously send CSI-RS based on a single CSI-RS resource set.

[0107] The UE can simultaneously perform measurements on CSI-RS transmitted by two TRPs.

[0108] In one possible implementation, the UE can perform receive beam scanning in multiple directions based on multiple antenna panels.

[0109] In one possible implementation, the UE can perform receive beam scanning in multiple directions based on an antenna panel.

[0110] In one embodiment, the measurement of the network device using multiple TRPs respectively based on a CSI-RS resource set for CRI-RS transmission includes:

[0111] Based on the received beam scanning capability, the CRI-RS transmitted by the network device is measured.

[0112] In one possible implementation, for one of multiple CSI-RS resource sets, the network-side device can transmit CSI-RS based on the CSI-RS resources in that CSI-RS resource set. The UE can then perform beam scanning based on the receive beam scanning capability corresponding to that CSI-RS resource set.

[0113] For example, if the receive beam scanning capability corresponding to the CSI-RS resource set is to perform M receive 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 receive beam scans, that is, it measures the CSI-RS on M receive beams.

[0114] In one possible implementation, if the network device simultaneously transmits CSI-RS using N TRPs, the UE can simultaneously scan N receive beams, meaning the UE can simultaneously measure CSI-RS on N receive beams. Here, the N receive beams can be implemented using one or more antennas of the UE through beamforming. Each TRP can transmit CSI-RS based on the CSI-RS resources of a separate CSI-RS resource set, and the UE can simultaneously use different receive beams to measure CSI-RS associated with different CSI-RS resource sets.

[0115] like Figure 6 As shown, this disclosure provides an information transmission method, which is executed by a network device and includes:

[0116] Step 601: Receive capability information sent by the UE, wherein the capability information is used to indicate the UE's receive beam scanning capability for at least one CSI-RS resource set, wherein the capability information is determined by the UE when it determines that there are multiple Channel State Information Reference Signal (CSI-RS) resource sets and that the multiple CSI-RS resource sets are associated with multiple Transmit and Receive Points (TRPs) of the network device, and the receive beam scanning capability is used to indicate the number of receive beams that the UE scans for one CSI-RS resource in the CSI-RS resource set.

[0117] In one possible implementation, the network device sends indication information, and the UE can determine, based on the indication information sent to the UE by the network device, that the network device uses multiple TRPs for signal transmission.

[0118] Multiple CSI-RS resource sets are associated with multiple Transmit / Receive Points (TRPs) of the network device, and the network device can use multiple TRPs to transmit CSI-RS based on multiple CSI-RS resource sets.

[0119] In one possible implementation, network devices can use multiple TRPs to send CSI-RS based on the CSI-RS resource set corresponding to each TRP at the same time, wherein one TRP can correspond to one CSI-RS resource set.

[0120] In one possible implementation, the network device can send multiple CSI-RS resource sets to the UE. The UE can determine the number of CSI-RS resource sets based on the received CSI-RS resource sets.

[0121] The UE can confirm its receive beam scanning capability for each CSI-RS resource set, which may include: the number of receive 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 a CSI-RS resource in the CSI-RS resource set; that is, the number of times the UE performs receive beam scanning for a CSI-RS resource in the CSI-RS resource set.

[0122] In this way, the network device determines the receive beam scanning capability of the UE for each CSI-RS resource set based on the capability information, which improves the accuracy of the network device in determining the UE's receive beam scanning capability, reduces the network device's misjudgment of the UE's receive beam scanning capability, and reduces resource configuration errors caused by the network device's misjudgment of the UE's receive beam scanning capability.

[0123] In one embodiment, the receive beam scanning capability corresponding to each CSI-RS resource set is determined by the UE based on each CSI-RS resource set.

[0124] For different CSI-RS resource sets, the receive beam scanning capability adopted by the UE can vary due to differences in parameters such as configured transmission resources. Therefore, the UE can determine the receive beam scanning capability corresponding to different CSI-RS resource sets. For example, it can determine the receive beam scanning capability corresponding to resource 1 as capability 1, and the receive beam scanning capability corresponding to resource 2 as capability 2. The receive beam scanning capability determined by the UE can be the same or different for different CSI-RS resource sets.

[0125] For example, a network device can transmit CSI-RS using two TRPs, each employing a CSI-RS resource set. The UE uses different receive beam scanning capabilities to receive CSI-RS for different CSI-RS resource sets.

[0126] In related technologies, the UE does not determine the receive beam scanning capability based on the CSI-RS resource set. Instead, 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, resulting in a mismatch between the receive beam scanning capability and the CSI-RS resource set.

[0127] The UE can determine the corresponding receive beam scanning capability for different CSI-RS resource sets and send capability information to the network device, indicating the receive beam scanning capability for at least one CSI-RS resource set.

[0128] For example, capability information can indicate the UE's receive beam scanning capability for each CSI-RS resource set. The network device can determine the UE's receive beam scanning capability for each CSI-RS resource set, thereby determining the time required for the UE to perform CSI-RS measurements, etc.

[0129] For example, 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 receive beam scanning capability 1 of the CSI-RS resource set 1.

[0130] like Figure 7 As shown, this disclosure provides an information transmission method, which is executed by a network device and includes:

[0131] Step 701: Send indication information to the UE, wherein the indication information is used to determine the number of CSI-RS resource sets.

[0132] The network device can send the number of configured CSI-RS resource sets to the UE via indication information.

[0133] The UE can determine the number of CSI-RS resource sets based on the indication information sent by the network device, and determine the receive beam scanning capability for each CSI-RS resource set.

[0134] The indication information can indicate the number of CSI-RS resource sets. Alternatively, the indication information can indicate multiple CSI-RS resource sets, and the UE determines the number of CSI-RS resource sets based on the received CSI-RS resource sets. For example, the indication information can be PDSCH-Config.

[0135] For example, a network device can send CSI-ReportConfig to the UE. If the UE determines that it has configured 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 with more than one element, then after receiving the CSI-RS resource set configuration from 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.

[0136] like Figure 8 As shown, this disclosure provides an information transmission method, which is executed by a network device and includes:

[0137] Step 801: Determine the measurement duration based on the UE's receive beam scanning capability. The measurement duration is the measurement duration required for the UE to perform CSI-RS measurement on one CSI-RS resource. The set of CSI-RS resources corresponding to the receive beam scanning capability includes at least one of the CSI-RS resources.

[0138] A CSI-RS resource set may include one or more CSI-RS resources.

[0139] In one possible implementation, the receive beam scanning capability can be at the CSI-RS resource set granularity. That is, a CSI-RS resource set can correspond to a receive beam scanning capability, and any CSI-RS resource in the CSI-RS resource set corresponds to that receive beam scanning capability.

[0140] Network devices transmit CSI-RS data in CSI-RS resources. The network device needs to determine the duration for which the UE performs CSI-RS measurements on a given CSI-RS resource in order to configure subsequent resources for the UE.

[0141] The receive beam scanning capability corresponding to a 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 be represented by the number N times the UE performs a receive beam scan on a CSI-RS resource in the CSI-RS resource set. That is, the terminal needs to perform maxNumberRxBeamSeti beam scans to complete a 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 that CSI-RS resource. maxNumberRxBeamSeti is the receive beam scanning capability.

[0142] The network device determines the receive beam scanning capability, that is, it determines the number of times N the UE performs receive beam scanning 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.

[0143] In one embodiment, the measurement duration is determined based on the receiving beam scanning capability and the single-wavelength measurement duration required for the UE to perform the CSI-RS measurement within a receiving beam.

[0144] The single-wave measurement duration required for the UE to perform the CSI-RS measurement within a receiving beam can be the duration of the UE performing one receiving beam scan, i.e., the duration of scanning using one receiving beam.

[0145] The network device can determine the duration of a CSI-RS measurement performed by the UE for a CSI-RS resource based at least on the number N of receive beam scans performed by the UE for a CSI-RS resource in the CSI-RS resource set, and the duration of one receive beam scan.

[0146] For example, the receive beam scanning capability corresponding to a CSI-RS resource set can be applied 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 the value between [1,8]. This value means 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 and obtain an accurate L1-RSRP measurement value. For the L1-RSRP measurement time based on the configured 1 beam scan, i.e., the single-wavelength measurement duration Tmeasure, the actual time required for the terminal to complete the measurement of a CSI-RS resource is: Ttotal = Tmeasure * maxNumberRxBeamSeti.

[0147] In one embodiment, the single-wavelength measurement duration is determined based on the method by which the UE performs the CSI-RS measurement and / or the measurement cycle of the CSI-RS.

[0148] Here, the method by which the UE performs the CSI-RS measurement corresponds to different measurement durations. The CSI-RS measurement method includes, but is not limited to, the frequency domain location used for the CSI-RS measurement, such as in-band measurement or out-of-band measurement.

[0149] The CSI-RS measurement period is related to the interval at which the UE performs CSI-RS measurements.

[0150] In one embodiment, the time-domain resources contained in the plurality of CSI-RS resource sets overlap;

[0151] The method further includes transmitting CSI-RS based on multiple CSI-RS resources over the overlapping time-domain resources.

[0152] The time-domain resources contained in a CSI-RS resource set can overlap. Network-side devices can simultaneously send CSI-RS based on multiple CSI-RS resource sets.

[0153] In one possible implementation, the network device can use multiple TRPs to send CSI-RS, with each TRP sending CSI-RS based on a CSI-RS resource set. In this way, multiple TRPs can send CSI-RS corresponding to multiple CSI-RS resource sets on overlapping time-domain resources.

[0154] The UE can measure CSI-RS transmitted by multiple TRPs on overlapping time-domain resources.

[0155] In one possible implementation, the UE can simultaneously measure CSI-RS in multiple receive beam directions, where one receive beam can correspond to the CSI-RS transmitted by a TRP.

[0156] For example, a network device has two Transmission Points (TRPs), each of which transmits CSI-RS on overlapping time-domain resources based on a CSI-RS resource set. The UE uses two beams simultaneously to measure the CSI-RS transmitted by one TRP.

[0157] like Figure 9 As shown, this disclosure provides an information transmission method, which is executed by a network device and includes:

[0158] Step 901: Send CRI-RS using multiple TRPs respectively, wherein each TRP corresponds to one of the multiple CSI-RS resource sets.

[0159] In one possible implementation, N TRPs can each send CSI-RS based on a CSI-RS resource set. That is, N TRPs can correspond to N CSI-RS resource sets.

[0160] For example, a network device may have two TRPs, and the two TRPs may simultaneously send CSI-RS based on a single CSI-RS resource set.

[0161] The UE can simultaneously perform measurements on CSI-RS transmitted by two TRPs.

[0162] In one possible implementation, the UE can perform receive beam scanning in multiple directions based on multiple antenna panels.

[0163] In one possible implementation, the UE can perform receive beam scanning in multiple directions based on an antenna panel.

[0164] like Figure 10 As shown, this disclosure provides an information transmission method, which is executed by a communication system, the communication system including a UE and a network device, the method comprising:

[0166] Step 1002: The network-side device receives capability information sent by the user equipment (UE).

[0181] like Figure 13 As shown, this disclosure provides an information transmission method, which is executed by a communication system and includes:

[0182] Step 1301: The network device determines the measurement duration based on the UE's receive beam scanning capability. The measurement duration is the measurement duration required for the UE to perform CSI-RS measurement on one CSI-RS resource. The set of CSI-RS resources corresponding to the receive beam scanning capability includes at least one CSI-RS resource.

[0183] For optional implementations of step 1301, please refer to [link / reference]. Figure 8 The other related parts involved in step 801 of the embodiments will not be described again here.

[0184] In some embodiments, the above methods may include the methods described in the embodiments on the UE side, network device side, etc., which will not be repeated here.

[0185] In one embodiment, the measurement duration is determined based on the receiving beam scanning capability and the single-wavelength measurement duration required for the UE to perform the CSI-RS measurement within a receiving beam.

[0186] In some embodiments, the above methods may include the methods described in the embodiments on the UE side, network device side, etc., which will not be repeated here.

[0187] The information transmission method executed by the communication system includes an information transmission method executed by the UE and an information transmission method executed by the network device. Its optional implementation methods are similar to those described in the embodiments on the UE side and network device side, and will not be repeated here. Several specific examples are provided below in conjunction with any of the above embodiments:

[0188] The network device issues configurations for multiple CSI-RS resource sets. The UE, based on the CSI-RS resource sets configured by the network, sends the supported receive beam scanning capability for the i-th CSI-RS resource set: maxNumberRxBeamseti.

[0189] Example 1:

[0190] If groupBasedBeamReporting-r17 is configured in CSI-ReportConfig, and nzp-CSI-RS-ResourceSetList configured in the CSI-ResourceConfig Information Element (IE) contains more than one CSI-RS resource set, 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 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 this receive beam scanning capability.

[0191] Example 2:

[0192] For the i-th resource set, the value of maxNumberRxBeamSeti can be between [1, 8]. This value means that the UE needs to perform maxNumberRxBeamSeti beam scans to complete a full receive beam scan of 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. Here, Tmeasure is determined based on the UE measurement behavior (UE measurement mode) configured by the network and the period of the measured CSI-RS.
