[0053] FIG1 shows a block diagram of a wireless communication system applicable to an embodiment of the present application.

[0054] As shown in Figure 1, the wireless communication system includes a terminal 11, a network-side device 12, and an environmental IoT device 13. Terminal 11 acts as an intermediate node. Network-side device 12 controls terminal 11 through air interface signaling. Terminal 11 stimulates environmental IoT device 13 through a downlink carrier. Environmental IoT device 13 backscatters the downlink carrier sent by the terminal to achieve uplink transmission to terminal 11. Terminal 11 then forwards the uplink transmission from environmental IoT device 13 to network-side device 12 over the air interface.

[0055] Of course, the network-side device 12 can also serve as a carrier source, and the network-side device 12 can stimulate the environmental IoT device 13 through the downlink carrier. The environmental IoT device 13 backscatters the downlink carrier sent by the network-side device 12 to achieve uplink transmission to the network-side device 12. In addition, sidelink transmission can also be performed between two terminals 11, which is not specifically limited in this application.

[0059] The ambient IoT device 13 may also be referred to as a passive IoT device, an ambient power (AMP) device, a zero-power device, a low-power IoT device, a response device, a tag, etc. It should be noted that the specific type of the ambient IoT device 13 is not limited in the embodiments of the present application.

[0060] In order to facilitate a better understanding of the embodiments of the present application, the technologies related to the present application are explained.

[0061] 1. Multiple antennas and beams.

[0062] Wireless access technology standards such as New Radio (NR) and Long Term Evolution (LTE) are based on Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) technologies. MIMO leverages the spatial freedom afforded by multi-antenna systems to improve peak data rates and system spectrum efficiency.

[0063] Massive MIMO technology uses large-scale antenna arrays to greatly improve the system's frequency band utilization efficiency and support a larger number of access users.

[0064] In massive MIMO technology, beamforming technology has great practical prospects in systems with high frequency bands, large bandwidth or a large number of antennas.

[0065] 2. Beam measurement and beam reporting.

[0066] After performing beam measurement, the terminal returns a beam report, which typically includes the identifiers of several optimal transmit beams and the measured receive power of each transmit beam.

[0067] When performing beam measurement, the network configures a reference signal resource set (RS resource set), which includes at least one RS resource, such as a synchronization signal block (SSB) resource or a channel state information reference signal (CSI-RS) resource. The user equipment (UE) measures the Layer 1 Reference Signal Received Power (L1-RSRP) / Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) of each RS resource and reports the best measurement result to the network. The report includes the SSB Resource Indicator (SSBRI) or CSI-RS Resource Indicator (CRI) and the L1-RSRP / L1-SINR. This report reflects the best beam and its quality, which the network uses to determine the beam to use for transmitting channels or signals to the UE.

[0068] 3. Beam indication mechanism.

[0069] After beam measurement and beam reporting, the network can make beam indications for the downlink and uplink channels or reference signals to establish a beam link between the network and the UE to achieve channel or reference signal transmission.

[0070] For Physical Downlink Control Channel (PDCCH) beam indication, the network uses Radio Resource Control (RRC) signaling to configure K Transmission Configuration Indication (TCI) states for each Control Resource Set (CORESET). When K > 1, a Media Access Control (MAC) Control Element (CE) indicates or activates one TCI state. When K = 1, no additional MAC CE command is required. When monitoring the PDCCH, the UE uses the same quasi-co-located (QCL), or TCI state, for all search spaces within the CORESET. Reference signals in this TCI state, such as periodic CSI-RS resources, semi-persistent (also known as semi-static) CSI-RS resources, SSBs, and UE-specific PDCCH Demodulation Reference Signal (DMRS) ports, are spatially QCLed. The UE can know which receiving beam to use to receive the PDCCH based on the TCI status.

[0071] For the beam indication of the Physical Downlink Shared Channel (PDSCH), the network configures M TCI states through RRC signaling and then activates 2 using the MAC CE command. N The TCI state is then notified through the N-bit TCI field of the downlink control information (DCI). The reference signal in this TCI state is QCL with the DMRS port of the scheduled PDSCH. Based on this TCI state, the UE can determine which receive beam to use to receive the PDSCH.

[0072] For CSI-RS beam indication, when the CSI-RS type is periodic CSI-RS, the network configures QCL information for the CSI-RS resource through RRC signaling. When the CSI-RS type is semi-persistent (also known as semi-static) CSI-RS, the network indicates its QCL information when activating a CSI-RS resource from the RRC-configured CSI-RS resource set through a MAC CE command. When the CSI-RS type is aperiodic CSI-RS, the network configures QCL for the CSI-RS resource through RRC signaling and uses DCI to trigger the CSI-RS.

[0073] For Physical Uplink Control Channel (PUCCH) beam indication, the network uses RRC signaling to configure spatial relation information for each PUCCH resource through the parameter PUCCH spatial relation information (SpatialRelationInfo). When multiple pieces of spatial relation information are configured for a PUCCH resource, MAC-CE is used to indicate or activate one of the pieces of spatial relation information. When only one piece of spatial relation information is configured for a PUCCH resource, no additional MAC CE command is required.

[0074] For the beam indication of the Physical Uplink Shared Channel (PUSCH), the spatial relationship information of the PUSCH is that when the DCI carried by the PDCCH schedules the PUSCH, each SRI code point in the spatial relationship information (SRI) field in the DCI indicates an SRI, and the SRI is used to indicate the spatial relationship information of the PUSCH.

[0075] For Sounding Reference Signal (SRS) beam indication, when the SRS type is periodic, the network configures spatial relationship information for the SRS resource through RRC signaling. When the SRS type is semi-persistent (also known as semi-static), the network activates one of the spatial relationship information sets configured by RRC through a MAC CE command. When the SRS type is aperiodic, the network configures spatial relationship information for the SRS resource through RRC signaling.

[0076] It is worth noting that:

[0077] The aforementioned terms, such as beam information, spatial relationship information, spatial domain transmission filter information, spatial filter information, TCI status, QCL information, and QCL parameters, are generally synonymous. Downlink beam information is typically represented by TCI status and QCL information. Uplink beam information is typically represented by spatial relationship information.

[0078] 4. Ambient IoT (A-IoT).

[0079] A-IoT is a new 3GPP IoT technology under research. A-IoT terminals have ultra-low complexity and ultra-low power consumption.

[0080] A-IoT, also known as the ambient power-enabled Internet of Things (Ambient Power-Enabled IoT), corresponds to a type of IoT service in which IoT devices are powered by energy harvesting. IoT devices lack batteries or have limited energy storage capabilities (for example, using a capacitor). Energy harvesting can be done from radio waves, light, motion, heat, or other suitable energy sources.

[0081] Low-power IoT devices are IoT devices with low overall power consumption, including low-power signal reception and low-power signal transmission. Because low-power IoT devices have low overall power consumption, they can generate communication energy from environmental sources such as wind, kinetic energy, thermal energy, and radio frequency (RF) signals. They are also referred to as A-IoT, passive IoT devices, and transponder devices.

[0082] A-IoT terminals can be classified based on energy source, energy storage capability, passive or active transmission, etc. It includes multiple types of devices:

[0083] Device Type A: A passive device with or without energy storage. It does not have independent signal generation or amplification, i.e., backscatter transmission.

[0084] Device Type B: A semi-passive device, also within the passive device category. It has energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy can include amplification of reflected signals.

[0085] Device Type C: An active device with energy storage and independent signal generation, i.e., active RF components for transmission.

[0086] In other words, A-IoT devices can be classified based on energy source, energy storage capability, passive or active emission, etc., including the following types of devices:

[0087] Passive devices with energy storage: They do not have independent signal generation or amplification capabilities and use backscattering technology for data transmission.

[0088] Semi-passive devices with energy storage: These devices have energy storage capabilities but no independent signal generation capabilities. They use backscattering technology for data transmission and can amplify reflected signals.

[0089] Active Device: It has energy storage and independent signal generation capabilities, that is, it has active RF components for data transmission.

[0090] Passive devices without energy storage: they use backscatter technology for data transmission.

[0091] 5. Backscatter Communication (BSC)

[0092] FIG2 is a schematic diagram of a process for providing scattering communication according to an embodiment of the present application.

[0093] As shown in Figure 2, the reader sends a radio frequency signal to the tag through the reader-to-tag link, and the tag sends a backscattered signal of the radio frequency signal to the reader through the tag-to-reader link.

[0094] Backscatter communication refers to the use of radio frequency signals from other devices or the environment to modulate the signal and transmit its own information. Backscatter technology, a passive or low-energy technology, is characterized by its ability to transmit its own signal by modifying the characteristics of the received ambient radio frequency signal, such as its phase or amplitude, to achieve extremely low or zero power consumption.

[0095] As an implementation method, as shown in FIG3 , when the tag needs to send a '1', the tag reflects the incident carrier signal, and when the tag needs to send a '0', the tag does not reflect.

[0096] Backscatter communication equipment controls the circuit's reflection coefficient Γ by adjusting its internal impedance, thereby changing the amplitude, frequency, and phase of the incident signal to achieve signal modulation. The signal reflection coefficient can be expressed as: Γ = (Z_1-Z_0) / (Z_1+Z_0) = |Γ|e^(jθ_T)

[0097] Where Z_0 is the antenna characteristic impedance, and Z_1 is the load impedance. Assuming the incident signal is S_in(t), the output signal is S_out(t) = S_in(t)|Γ|e^(jθ_T). Therefore, by properly controlling the reflection coefficient, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved.

[0098] Backscatter communication reception is typically low-power, typically using low-power RF, IF, or baseband envelope detection. The waveform of the transmitted signal typically uses simple modulation methods such as OOK, ASK, and FSK.

[0099] The device that communicates with such low-power devices is called a read-write device, which can be, for example, a terminal, a base station, or a device with read-write functions, such as a reader / writer, and the specifics are not limited here.

[0100] 6.A-IoT data / service type.

[0101] A-IoT data / service types may include the following:

[0102] Device-originated (DO) communication.

[0103] The communication is terminated at the device (Device-terminated, DT).

[0104] A-IoT devices autonomously initiate data transmission (Device-originated–autonomous, DO-A).

[0105] A-IoT devices are triggered by reader / writer devices such as base stations (Device-originated–device-terminated triggered, DO-DTT).

[0106] DO and DT data represent data flows originating from A-IoT devices (similar to RFID tags) or transmitted to A-IoT devices. Data flows originating from A-IoT devices, i.e., DO data, can be further categorized as follows:

[0107] DO-A, for example: connecting a large number of various sensors that collect and, when necessary, proactively report information about the environment, equipment, and organisms.

[0108] DO-DTT, such as asset identification, status reporting, and tracking, are all downlink (DL) triggered reports where the reader collects data from the tag by triggering an inventory process. Since the data is generated / initiated in the IoT device, this service should be considered a DO service initiated by the tag, triggered by a command sent by the reader.

[0109] 7. Information transmission between readers and writers in Radio Frequency Identification (RFID).

[0110] RFID is a traditional backscatter communication system designed to identify and read data from BSC devices (i.e., tags) within the reader's coverage area. Because RFID was initially used for automated inventory counting of large quantities of goods, the process of tag identification and data reading is also known as inventory taking.

[0111] Taking the EPC C1G2 RFID system defined in ISO 18000-6c as an example, as shown in Figure 4, after the reader sends a query command (Query), the tag responds with a reply (Reply). For example, if the reply is RN16, the tag generates a 16-bit random number and sends it to the reader. The reader then sends this sequence to the tag via an acknowledgment (ACK) command. After successfully verifying the RN16 in the ACK, the tag sends subsequent data (such as the protocol control (PC) / extended protocol control (XPC), electronic article code (EPC), and cyclic redundancy check (CRC)) to the reader.

[0112] As shown in Figure 5, the operating instructions of the reader are shown in the following table:

[0113] Table 1

[0114] As shown in Figure 5, the status of the Tag tag is shown in the following table:

[0115] Table 2

[0116] An embodiment of the present application provides a beam management method that can determine a beam while reducing the power consumption of a terminal.

[0117] The beam management method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0118] FIG6 is a schematic flowchart of a beam management method 210 according to an embodiment of the present application.

[0119] As shown in FIG6 , the beam management method 210 may include at least part of the following:

[0120] S211, the terminal obtains information of the first environment IoT device.

[0121] S212: The terminal determines a first beam based on information of the first environment IoT device.

[0122] Exemplarily, the first beam is a beam suitable for the terminal, a beam used by the terminal, a candidate beam of the terminal, or a usable beam of the terminal.

[0123] Exemplarily, the terminal may determine one or more first beams.

[0124] In an embodiment of the present application, the terminal obtains information about the first environment IoT device, and determines the first beam based on the information about the first environment IoT device, thereby avoiding the terminal determining the beam by polling and measuring all beams, that is, the beam can be determined on the basis of reducing power consumption.

[0125] It's understandable that a specific area within a cell has a suitable beam. Since ambient IoT devices are deployed at relatively fixed locations within the cell, information from these devices can be used to determine the beam for devices at that location. Furthermore, beam determination based on information from these devices can avoid misjudgments that could be made through measurement alone.

[0126] In some embodiments, the information of the first environment IoT device includes at least one of the following:

[0132] Identification information of the first environment IoT device:

[0133] Information about the first area to which the first environment IoT device belongs.

[0134] It can be understood that for a certain area of ​​a cell, there is a suitable beam, and the environmental Internet of Things devices are deployed in a relatively fixed position in the cell. Therefore, the identification information of the environmental Internet of Things devices and the area to which they belong can be used to identify the location of the terminal that can obtain the corresponding information.

[0135] In some embodiments, the information of the first area includes at least one of the following: identification information of the first area, and identification information of one or more cells to which the first area belongs.

[0136] Exemplarily, the one or more cells include a serving cell or a neighboring cell of the terminal.

[0137] In some embodiments, the S212 includes:

[0140] In some embodiments, the S212 includes:

[0141] The terminal determines the first beam based on the beam corresponding to the information of the first environment IoT device.

[0142] Exemplarily, the terminal may determine the beam corresponding to the information of the first environmental IoT device as the first beam. Alternatively, the terminal may select or determine the first beam from among the beams corresponding to the information of the first environmental IoT device.

[0143] In some embodiments, before S212, the method 210 further includes:

[0144] The terminal receives a first correspondence from a network-side device or a first device, where the first correspondence includes a correspondence between at least one information and at least one beam information, and the at least one information includes information of the first environment IoT device;

[0145] Wherein, the S212 includes:

[0146] The terminal determines the first beam based on the first corresponding relationship and information about the first environment IoT device.

[0147] Exemplarily, the first device may be a third-party server, an application function (AF) or other device.

[0148] Exemplarily, the first corresponding relationship is transmitted via system information or a reconfiguration message.

[0149] Of course, in other alternative embodiments, the terminal may first determine the first position corresponding to the information of the first environmental IoT device, and then determine the first beam based on the beam corresponding to the first position. Optionally, before determining the first beam, the terminal may also receive at least one of the second correspondence and the third correspondence from the network-side device or the first device, wherein the first correspondence includes a correspondence between at least one information and at least one position, the second correspondence includes a correspondence between at least one position and at least one beam, the at least one information includes the information of the first environmental IoT device, and the at least one position includes the first position. Based on this, the terminal may determine the first beam based on the second correspondence, the third correspondence, and the information of the first environmental IoT device.

[0150] In some embodiments, before S212, the method 210 further includes:

[0151] The terminal receives at least one of the following from the network side device:

[0152] First indication information, where the first indication information is used to indicate that the terminal is allowed to determine a beam based on information of an environmental IoT device;

[0153] Second indication information, the second indication information is used to indicate support for area division based on environmental Internet of Things devices.

[0154] Exemplarily, when the indication allows the terminal to determine the beam based on the information of the environmental Internet of Things device or supports area division based on the environmental Internet of Things device, the terminal determines the first beam based on the information of the first environmental Internet of Things device.

[0155] In some embodiments, the method 210 further includes:

[0156] The terminal ignores or does not use beams other than the first beam, or the terminal uses the first beam to perform a first operation, where the first operation includes at least one of the following:

[0157] Beam measurement;

[0158] Monitor paging messages;

[0159] Initiate random access.

[0160] In this embodiment, the terminal ignores or does not use beams other than the first beam, or the terminal performs the first operation using the first beam, thereby avoiding performing operations on beams other than the first beam and reducing terminal power consumption. For example, performing a task only on the first beam can effectively reduce task execution time, thereby reducing terminal power consumption.

[0161] It is understood that the network uses N beams to perform tasks such as paging, sending reference signals, and random access. The terminal can determine M first beams based on information about the surrounding IoT devices, where M is less than N. In other words, the terminal can use only the first beam of the M first beams to perform the first operations, namely, beam measurement, monitoring paging messages, and initiating random access, thereby reducing terminal power consumption and improving communication performance.

[0162] In some embodiments, before the terminal ignores or does not use beams other than the first beam, or before the terminal uses the first beam to perform the first operation, the method 210 further includes:

[0163] The terminal receives third indication information from the network side device, where the third indication information is used to indicate that the terminal is allowed to use the beam determined by information of the environmental Internet of Things device.

[0164] In some embodiments, the method 210 further includes:

[0165] The terminal sends first information to the network side device, where the first information includes at least one of the following:

[0166] information of the first beam;

[0167] a measurement result obtained by the terminal measuring the first beam;

[0168] Information used to identify the location of the terminal in the information of the first environment Internet of Things device.

[0169] Exemplarily, the first information may be a beam report or a measurement report. For example, the beam report may include information about the first beam, and the measurement report may include information about the first beam, a measurement result obtained by the terminal measuring the first beam, and information used to identify the location of the terminal in the information of the first environment IoT device.

[0170] In this embodiment, by reporting the first information, reporting information related to beams other than the first beam is avoided, which not only saves transmission resources but also reduces power consumption of the terminal. Furthermore, when the network device performs beam indication or beam switching based on the first information, it can not only narrow the range of the indicated or switched beams, but also ensure beam switching performance.

[0171] In some embodiments, before the terminal sends the first information to the network-side device, the method 210 further includes:

[0172] The terminal receives fourth indication information from the network side device, and the fourth indication information is used to indicate that the terminal is allowed to report information based on the beam determined by the information of the Internet of Things device.

[0173] In some embodiments, the method 210 further includes:

[0174] The terminal receives a Layer 1 / Layer 2 Triggered Mobility Procedure (LTM) command from the network side device;

[0175] The candidate configuration included in the LTM command is determined according to the first information.

[0176] Exemplarily, the candidate configuration is used to perform LTM switching or conditional LTM switching.Exemplarily, the candidate configuration may be an LTM configuration, and the LTM configuration is beam-related.

[0177] Exemplarily, the LTM command may also be understood as or equivalently replaced by: a beam switching command or beam indication information.

[0178] In this embodiment, since the first information is information related to the first beam, and the candidate configuration contained in the LTM command is determined based on the first information, the LTM command is avoided from including configurations related to beams other than the first beam. This not only reduces the number of candidate configurations included in the LTM command, but also ensures the performance of beam switching.

[0179] In some embodiments, the S211 includes:

[0180] The terminal obtains information about the first environment IoT device by at least one of the following:

[0181] Inventory environmental IoT devices, detect environmental IoT devices, measure environmental IoT devices, and read the information contained in environmental IoT devices.

[0182] FIG7 is a schematic flowchart of a beam management method 220 according to an embodiment of the present application.

[0183] As shown in FIG7 , the beam management method 220 may include at least part of the following:

[0188] In an embodiment of the present application, a network-side device receives first information from a terminal, and the first information includes at least one of the following: information of a first beam determined by the terminal based on information of a first-environment IoT device; a measurement result obtained by the terminal measuring the first beam; since the information of the first-environment IoT device can be used by the terminal to determine the first beam, the terminal avoids determining the beam by polling and measuring all beams, that is, it can determine the beam on the basis of reducing power consumption.

[0189] In some embodiments, the information of the first environment IoT device includes at least one of the following:

[0190] Information for indicating a beam;

[0191] Identification information of the first environment IoT device:

[0194] In some embodiments, before S221, the method 220 further includes:

[0196] A first correspondence relationship, where the first correspondence relationship includes a correspondence relationship between at least one information and at least one beam information, where the at least one information includes information of the first environment IoT device;

[0197] First indication information, where the first indication information is used to indicate that the terminal is allowed to determine a beam based on information of an environmental IoT device;

[0198] Second indication information, where the second indication information is used to indicate support for regional division based on environmental IoT devices;

[0199] The third indication information is used to indicate that the terminal is allowed to use the beam determined by the information of the environmental Internet of Things device.

[0201] The network side device sends fourth indication information to the terminal, where the fourth indication information is used to indicate that the terminal is allowed to report information based on the beam determined by the information of the Internet of Things device.

[0202] In some embodiments, the method 220 further includes:

[0203] The network-side device determines, based on the first information, candidate configurations included in a layer 1-2 triggered mobility process LTM command;

[0204] The network side device sends the LTM command to the terminal.

[0205] It should be understood that the solution of method 220 provided in the embodiment of the present application can refer to the relevant content of the above-mentioned method 210. For the sake of brevity, it will not be repeated here.

[0206] The solution of this application is described below with reference to specific embodiments.

[0207] Example 1:

[0208] In this embodiment, the terminal may obtain information of the first environment IoT device, and determine the first beam based on the beam indicated by the information of the first environment IoT device.

[0209] The information of the first environment IoT device includes information for indicating a beam.

[0210] Exemplarily, the terminal may determine the beam indicated by the information of the first environmental IoT device as the first beam. Alternatively, the terminal may select or determine the first beam from among the beams indicated by the information of the first environmental IoT device.

[0211] Exemplarily, before the terminal device determines the first beam, the terminal device receives at least one of the following from a network-side device:

[0212] First indication information, where the first indication information is used to indicate that the terminal is allowed to determine a beam based on information of an environmental IoT device;

[0213] Second indication information, the second indication information is used to indicate support for area division based on environmental Internet of Things devices.

[0214] Exemplarily, when the indication allows the terminal to determine a beam based on information of the environmental Internet of Things device or supports area division based on the environmental Internet of Things device, the terminal determines the first beam based on the beam indicated by the information of the first environmental Internet of Things device.

[0215] Example 2:

[0216] In this embodiment, the terminal can obtain information about the first environment Internet of Things device, and determine the first beam based on the beam corresponding to the information of the first environment Internet of Things device.

[0217] The information of the first environment IoT device includes at least one of the following: identification information of the first environment IoT device and information of the first area to which the first environment IoT device belongs. The first area may also be referred to as a grid or a network zone. At least one of the identification information of the first environment IoT device and the information of the first area to which the first environment IoT device belongs can be used to identify the location of the terminal. The information of the first area includes at least one of the following: identification information of the first area and identification information of one or more cells to which the first area belongs. The one or more cells include a serving cell or a neighboring cell of the terminal.

[0218] Exemplarily, before the terminal determines the first beam based on the beam corresponding to the information of the first environment Internet of Things device, the terminal receives a first correspondence from the network side device, and the first correspondence includes a correspondence between at least one information and at least one beam information, and the at least one information includes the information of the first environment Internet of Things device; thus, the terminal can determine the first beam based on the first correspondence and the information of the first environment Internet of Things device.

[0219] Exemplarily, before the terminal device determines the first beam, the terminal device receives at least one of the following from a network-side device:

[0220] First indication information, where the first indication information is used to indicate that the terminal is allowed to determine a beam based on information of an environmental IoT device;

[0221] Second indication information, the second indication information is used to indicate support for area division based on environmental Internet of Things devices.

[0222] In other words, when the indication allows the terminal to determine the beam based on the information of the environmental Internet of Things device or supports area division based on the environmental Internet of Things device, the terminal determines the first beam based on the beam corresponding to the information of the first environmental Internet of Things device.

[0223] Example 3:

[0224] In this embodiment, the terminal can obtain information about the first environment Internet of Things device, and determine the first beam based on the beam corresponding to the information of the first environment Internet of Things device.

[0225] The information of the first environment IoT device includes at least one of the following: identification information of the first environment IoT device and information of the first area to which the first environment IoT device belongs. The first area may also be referred to as a grid or a network zone. At least one of the identification information of the first environment IoT device and the information of the first area to which the first environment IoT device belongs can be used to identify the location of the terminal. The information of the first area includes at least one of the following: identification information of the first area and identification information of one or more cells to which the first area belongs. The one or more cells include a serving cell or a neighboring cell of the terminal.

[0226] Exemplarily, before the terminal determines the first beam based on the beam corresponding to the information of the first environment Internet of Things device, the terminal receives a first correspondence from the first device, and the first correspondence includes a correspondence between at least one information and at least one beam information, and the at least one information includes the information of the first environment Internet of Things device; thus, the terminal can determine the first beam based on the first correspondence and the information of the first environment Internet of Things device.

[0227] The first device may be a third-party server, an application function (AF) or other devices.

[0228] Exemplarily, before the terminal device determines the first beam, the terminal device receives at least one of the following from a network-side device:

[0229] First indication information, where the first indication information is used to indicate that the terminal is allowed to determine a beam based on information of an environmental IoT device;

[0230] Second indication information, the second indication information is used to indicate support for area division based on environmental Internet of Things devices.

[0231] In other words, when the indication allows the terminal to determine the beam based on the information of the environmental Internet of Things device or supports area division based on the environmental Internet of Things device, the terminal determines the first beam based on the beam corresponding to the information of the first environmental Internet of Things device.

[0232] Example 4:

[0233] In this embodiment, after determining the first beam according to any one of Embodiments 1 to 3, the terminal ignores or does not use beams other than the first beam, or uses the first beam to perform a first operation, where the first operation includes at least one of the following:

[0234] Beam measurement;

[0235] Monitor paging messages;

[0236] Initiate random access.

[0237] Exemplarily, the terminal ignores or does not use beams other than the first beam, or before the terminal uses the first beam to perform the first operation, the terminal receives third indication information from the network side device, and the third indication information is used to indicate that the terminal is allowed to use the beam determined by information of the environmental Internet of Things device.

[0238] In other words, when the terminal is allowed to use the beam determined by the information of the environmental IoT device, the terminal performs the first operation using the first beam.

[0239] In this embodiment, the terminal ignores or does not use beams other than the first beam, or the terminal performs the first operation using the first beam, thereby avoiding performing operations on beams other than the first beam and reducing terminal power consumption. For example, performing a task only on the first beam can effectively reduce task execution time, thereby reducing terminal power consumption.

[0240] It is understood that the network uses N beams to perform tasks such as paging, sending reference signals, and random access. The terminal can determine M first beams based on information about the surrounding IoT devices, where M is less than N. In other words, the terminal can use only the first beam of the M first beams to perform the first operations, namely, beam measurement, monitoring paging messages, and initiating random access, thereby reducing terminal power consumption and improving communication performance.

[0241] Example 5:

[0242] After the terminal determines the first beam according to any one of Embodiments 1 to 3, the terminal may send first information to the network-side device, where the first information includes at least one of the following:

[0243] information of the first beam;

[0244] a measurement result obtained by the terminal measuring the first beam;

[0245] Information used to identify the location of the terminal in the information of the first environment Internet of Things device.

[0246] Exemplarily, the first information may be a beam report or a measurement report. For example, the beam report may include information about the first beam, and the measurement report may include information about the first beam, a measurement result obtained by the terminal measuring the first beam, and information used to identify the location of the terminal in the information of the first environment IoT device.

[0247] Exemplarily, before the terminal sends the first information to the network side device, the terminal receives fourth indication information from the network side device, and the fourth indication information is used to indicate that the terminal is allowed to report information based on the beam determined by the information of the Internet of Things device.

[0248] In other words, when the terminal is allowed to report information based on the beam determined by the information of the Internet of Things device, the terminal sends the first information to the network side device.

[0249] In this embodiment, by reporting the first information, reporting information related to beams other than the first beam is avoided, which not only saves transmission resources but also reduces power consumption of the terminal. Furthermore, when the network device performs beam indication or beam switching based on the first information, it can not only narrow the range of the indicated or switched beams, but also ensure beam switching performance.

[0250] Example 6:

[0251] After the terminal determines the first beam according to any one of Examples 1 to 3, it can report the first information according to Example 5. After the network side device receives the first information, it can determine the candidate configuration included in the LTM command based on the first information, and then send the LTM command to the terminal.

[0252] Exemplarily, in a case where the first information includes information of the first beam, the network-side device may determine the candidate configuration included in the LTM command directly based on the information of the first beam.

[0253] Exemplarily, when the first information includes at least one of a measurement result obtained by the terminal measuring the first beam and information used to identify the location of the terminal in the information of the first environment IoT device, the network side device can determine the information of the first beam based on the measurement result obtained by the terminal measuring the first beam and at least one of the information used to identify the location of the terminal in the information of the first environment IoT device, and then determine the candidate configuration included in the LTM command based on the information of the first beam.

[0254] In this embodiment, since the first information is information related to the first beam, and the candidate configuration contained in the LTM command is determined based on the first information, the LTM command is avoided from including configurations related to beams other than the first beam. This not only reduces the number of candidate configurations included in the LTM command, but also ensures the performance of beam switching.

[0255] The beam management method provided in the embodiment of the present application can be executed by a beam management device. In the embodiment of the present application, the beam management device provided in the embodiment of the present application is described by taking the beam management device executing the beam management method as an example.
