Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information reporting method and a communication device. Background Art

[0002] At present, high-precision positioning technology is one of the key technologies of the fifth generation mobile communication technology new radio (5G NR) mobile communication network. Cellular positioning can accurately identify the location of user equipment (UE), thereby providing various location-based services such as navigation, transportation, industrial robots, etc. However, in the positioning capability for the sixth generation mobile communication technology (6G), it is expected to realize wireless perception capability through positioning reference signals, realize real-time perception of the environment through wireless perception capability, enable perception capability, and further improve positioning accuracy.

[0003] Specifically, the base station usually needs to use an antenna array (including multiple antennas) to measure the positioning reference signal from the UE, and report the measured measurement results (such as channel state information (CSI) or channel impulse response (CIR) or power delay profile (PDP)) to the positioning center, so as to build perception capabilities under the positioning network, further perceive the position of each reflector in the environment, and use the measurement information of the reflection path in space to improve the positioning accuracy in harsh channel environments. However, the reporting of channel measurement results often leads to higher signaling overhead and higher network load. Therefore, how to save the overhead of reporting channel measurement results is a problem to be solved. Summary of the invention

[0004] The embodiments of the present application provide an information reporting method and a communication device, which can save the overhead of reporting channel measurement results.

[0005] In a first aspect, the present application provides an information reporting method, the method comprising: receiving a measurement request message from a first network element, the measurement request message being used to request measurement channel information; reporting a first measurement result and first information to the first network element according to the measurement request message, the first information indicating first angle information or first beam information corresponding to the first measurement result.

[0006] In the method described in the first aspect, after receiving the measurement request message from the first network element, only the measurement results in one or more directions or only the measurement results within a certain range can be reported, thereby avoiding the reporting of omnidirectional multi-antenna measurement results, which is beneficial to saving the overhead of reporting channel measurement results.

[0007] In a possible implementation, the first information includes one or more first beam information corresponding to the first measurement result, and the first measurement result is calculated based on the second measurement result corresponding to the one or more first beam information. Based on this method, since the second measurement result corresponding to the one or more first beam information can be obtained by combining the measurement results obtained by measuring each antenna in the antenna array using beamforming, the reporting of omnidirectional multi-antenna measurement results is avoided, which is conducive to saving the overhead of reporting channel measurement results.

[0008] In a possible implementation, the first beam information includes one or more of the following information: a first angle value of the first beam, a first angle range of the first beam, an index value of the first beam, and an index value of a reference signal associated with the first beam.

Based on this approach, for a scenario where the first network element is only interested in channel measurement results within a certain characteristic direction or angle range, the first network element can instruct the access network device to report only measurement results within a partial range, thereby avoiding reporting of omnidirectional multi-antenna measurement results, which is beneficial to saving the overhead of reporting channel measurement results.

[0013] In a possible implementation, the first beam or the second beam is a beam at a diameter level. Based on this method, the energy of a certain diameter can be maximized.

[0014] In a possible implementation manner, the first information includes path information, where the path information is information of a path associated with the beam information.

[0066] See also Figure 2 , Figure 2 is a schematic diagram of a core network architecture provided by this application, Figure 2 The CN in Figure 1 is a schematic diagram of the CN in the 5G network architecture. Figure 2The CN shown includes multiple CN devices: network slice selection function (NSSF), network exposure function (NEF), network function repository function (NRF), policy control function (PCF), unified data management (UDM), application function (AF), network control function (NCF), network slice specific authentication and authorization function (NSSAAF), authentication server function (AUSF), access and mobility management function (AMF), location management function (LMF), session management function (SMF), user plane function (UPF), service communication proxy (SCP), network slice admission control (NSACF), etc. Among them:

[0067] AMF is a control plane function provided by the operator network, which is responsible for the access control and mobility management of the terminal device to the operator network, such as mobile state management, allocation of user temporary identity, authentication and authorization of users, etc. In the embodiment of the present application, AMF can receive a location information request about a UE initiated by other network elements in the network, and then send the received request to the positioning server LMF, which is responsible for processing the received location information request and initiating the relevant positioning process.

[0068] LMF is mainly used to provide location positioning for emergency rescue, navigation and location-based management services. LMF can determine the location information of UE according to the request of core network entities (such as access and mobility management function (AMF)), and provide the location information of UE to AMF, thereby providing location services (LCS). In the embodiment of the present application, the first network element may be LMF, LMF may be a location server / positioning center, may be integrated in the access network device, and may also be referred to as Local LMF. It should be noted that "positioning" can be translated into any one of location, positioning, position, localization, etc., that is, the above four words can be directly replaced with each other, and are not limited to the singular or plural. In addition, the two words "positioning" and "position" can also be directly replaced, for example, "positioning information request" and "positioning information request" can represent the same or similar meanings; "positioning center" and "positioning center" can represent the same or similar meanings, "positioning server" and "positioning server" can represent the same or similar meanings; and so on, the present invention is not limited.

A PDU session is a channel for transmitting PDUs. The terminal device needs to transmit PDUs to and from the DN through the PDU session.

Among them, the policy may include charging-related policies, QoS-related policies, and authorization-related policies.

Among them, UDR is used to provide storage and retrieval for PCF policies, storage and retrieval of open structured data, and storage of user information requested by application functions.

[0073] It should be noted that the above CN equipment can also be called network element or functional network element. In the 5G communication system, each functional network element can be Figure 2 The names of the functional network elements shown in the figure may still be the same in the communication system evolved after 5G (such as 6G communication system). Figure 2 The names of the functional network elements shown in the figure may also have other names. For example, in a 5G communication system, the user plane function may be a UPF. In a communication system evolved after 5G (such as a 6G communication system), the user plane function may still be a UPF, or may have other names, which is not limited in this application.

[0074] It should also be noted that in the 5G communication system, the functions implemented by each functional network element can be as follows: Figure 2 As shown, they are independent. In the communication system evolved after 5G (such as 6G communication system), each functional network element can still be Figure 2 The shown state is independent, but it can also be realized by integrated functional network elements. Figure 2 For example, in a 5G communication system, user-plane related functions are implemented by UPF, and access and mobility management related functions are implemented by AMF. In a communication system that evolves after 5G (such as a 6G communication system), user-plane related functions may still be implemented by UPF, and access and mobility management related functions may still be implemented by AMF. Alternatively, user-plane related functions and access and mobility management related functions may also be implemented by an integrated functional network element at the same time, which is not limited in this application.

[0078] In order to facilitate understanding of the solution provided by the embodiment of the present application, the following introduces the relevant concepts involved in the embodiment of the present application:

[0079] 1. Wireless sensing technology

[0080] Wireless sensing refers to the use of wireless signals to sense environmental information, including the distribution, size, quantity, temperature, human behavior, and even human breathing rate and heart rate. After sensing the environment, it can be combined with various other technologies, such as artificial intelligence technology, for subsequent processing to achieve reconstruction of the physical environment, analyze the environment, identify and analyze people and objects in the environment, trigger subsequent actions, etc. Through wireless sensing technology, important information about the environment covered by the wireless signal can be reconstructed on the computer without collecting images and videos on site.

[0081] The principle of wireless sensing is to transmit radio signals to the environment that needs to be sensed, and collect the wireless signals reflected, scattered, and transmitted through multiple paths in the environment at the receiving end. Since the collected wireless signals are involved in the environment, they carry information about the environment. After receiving the signal, after complex signal processing, the characteristics of the environment can be discovered, and the sensed environment can be reconstructed on the computer, including identifying people and objects in the environment, detecting temperature, detecting human movements, and even breathing frequency, heartbeat frequency, etc. It is used in the fields of personnel health detection, security, etc.

[0082] 2. Line of sight (LOS) path and non-line of sight (NLOS) path

[0083] In the cellular network mobile terminal positioning system, the LOS path refers to the straight path between the terminal device and the access network device; the NLOS path refers to the path where the straight path of radio wave transmission between the terminal device and the access network device is blocked due to the existence of obstacles in the wireless transmission environment, and the radio wave will propagate in NLOS propagation modes such as reflection, refraction and diffraction. Figure 3 As shown, the positioning reference signal can be transmitted between the terminal device and the access network device through a LOS path in a straight line, or can be transmitted through a reflector or scatterer through a NLOS path reflection transmission or diffraction transmission.

[0084] For traditional positioning methods such as time difference of arrival (TDOA) and angle of arrival (AOA), when the position of the scatterer / reflector is unknown, the terminal device cannot use the positioning reference signal transmitted through the NLOS path and the corresponding measurement. However, when the network has the perception capability, that is, it can sense the position of each scatterer in the environment, the positioning reference signal transmitted through the NLOS path can be used in the process of positioning the UE. In other words, by building the perception capability under the positioning network, the measurement information of the reflection path in space can be used to enable NLOS path positioning.

[0085] 3. Channel measurement results

[0086] For cellular positioning systems, in wireless sensing technology, terminal devices or access network devices are usually required to report the measurement results obtained by measuring the channel to the positioning center (such as LMF) to achieve wireless sensing. In addition, in addition to realizing wireless sensing, the reported measurement results can also realize wireless fingerprint positioning, that is, pre-build a wireless fingerprint library, and then match and compare the reported measurement results with the wireless fingerprint library to obtain the UE's location results. In an embodiment of the present application, the measurement results can be channel state information (CSI), channel impulse response (CIR), power delay profile (PDP), channel frequency domain coefficient (CFR), channel coefficient corresponding to the channel frequency domain subcarrier or channel coefficient corresponding to each resource element (RE), etc.

[0087] Specifically, the base station usually needs to use an antenna array (including multiple antennas) to measure the positioning reference signal from the UE, and report the measurement results obtained by each antenna to the positioning center, so as to build a perception capability under the positioning network, further perceive the position of each reflector in the environment, and use the measurement information of the reflection path in the space to improve the positioning accuracy in harsh channel environments. However, reporting the measurement results obtained by each antenna often leads to high signaling overhead and high network load. For example, for a frequency range 1 (FR1) orthogonal frequency division multiplexing (OFDM) system, 100MHz bandwidth, 4096 subcarriers, each subcarrier has two values ​​of in-phase and quadrature, each value is quantized with 16 bits, assuming that the base station or terminal device is equipped with 4 antennas, then the reporting overhead is: 4096*2*16*4*4=2097152 bits, which is bound to bring extremely high load to the network.

[0088] Therefore, in order to save the overhead of reporting channel measurement results, the present application provides an information reporting method and a communication device. The information reporting method and the communication device provided in the embodiments of the present application are further described in detail below.

[0089] Figure 4 Schematic diagram of a flow chart of an information reporting method provided in an embodiment of the present application. Figure 4 As shown, the information reporting method includes the following steps S401 and S402. Figure 4 The method execution subject shown may be the access network device and the first network element mentioned above. Or, Figure 4 The execution entity of the method shown may be a chip in the access network device and a chip in the first network element, which is not limited in the embodiments of the present application. Figure 4 The access network device and the first network element are used as the execution subjects of the method for example. In addition, the first network element can be an independent device or integrated in the access network device, which is not limited here. The embodiment of the present application is described by taking the first network element as an independent device as an example.

[0090] S401: A first network element sends a measurement request message to an access network device. Correspondingly, the access network device receives the measurement request message from the first network element.

[0091] In an embodiment of the present application, the measurement request message is used to request the measurement of channel information. The channel information requested for measurement here may refer to information related to the channel, such as CSI, CIR, PDP, CFR, channel angle information, channel delay information, channel frequency domain coefficient, channel coefficient corresponding to the frequency domain subcarrier of the channel, or channel coefficient corresponding to each RE, etc., which is not limited here. The first network element may be an LMF, or a positioning server or a positioning center, etc., which is not limited here.

[0092] It should be noted that "positioning" can be translated into any of location, positioning, position, localization, etc. Location, positioning, position, and localization can replace each other in different scenarios in this application. Positioning center, positioning server, location center, location management function, etc. can all express the same meaning, indicating nodes / functions / services / devices with location or positioning-related functions. In addition, the words "measurement message request" and "request measurement message", "provide measurement information" and "measurement information provision" do not affect the meaning when the order is changed. They can be directly replaced and also express the same meaning. This application does not limit the order of phrases.

[0093] S402: The access network device reports the first measurement result and the first information to the first network element according to the measurement request message. Correspondingly, the first network element receives the first measurement result and the first information from the access network device.

[0094] In an embodiment of the present application, the first information indicates the first angle information or the first beam information corresponding to the first measurement result. With respect to the specific process of the access network device reporting the first measurement result, first, the first network element needs to request the terminal device for the positioning capability information of the terminal device, and accordingly, the terminal device reports its positioning capability information to the first network element; then, the first network element requests the reference signal configuration information from the access network device according to the positioning capability information of the terminal device, and accordingly, the access network device determines the available reference signal resources and configuration, and after the determination, configures the reference signal resources to the terminal device through radio resource control (RRC) signaling; at the same time, the access network device will also inform the first network element of the reference signal configuration information. Among them, the reference signal can be a sounding reference signal (SRS). Further, the terminal device can send a reference signal to the access network device, and after receiving the measurement request message sent by the first network element, the access network device can measure the reference signal from the terminal device, obtain the first measurement result, and report the first measurement result to the first network element; the first network element can use the first measurement result to locate the terminal device.

[0095] The access network device is equipped with an antenna array, which may include multiple antennas. When the access network device measures the reference signal from the terminal device, a measurement result can be measured on each antenna. In order to avoid reporting the measurement results of omnidirectional multiple antennas and save the overhead of reporting channel measurement results, the access network device may only report the measurement results in one or more directions or within a certain angle range, that is, the first measurement result may be a measurement result in a certain direction or within a certain angle range. Therefore, in addition to reporting the first measurement result, the access network device also needs to indicate the first angle information or first beam information corresponding to the first measurement result.

[0096] It should be noted that the first angle information corresponding to the first measurement result can also be understood as the first angle information associated with the first measurement result; the first beam information corresponding to the first measurement result can also be understood as the first beam information associated with the first measurement result. In other words, the word "corresponding" can be interchanged with "associated".

[0097] In a possible implementation, the first measurement result includes one or more of the following information: CSI, CIR, PDP, CFR. Of course, the first measurement result may also be a channel coefficient corresponding to a channel frequency domain subcarrier or a channel coefficient corresponding to each RE, etc., which is not limited here.

[0098] Regarding the case where the first information may indicate the first angle information or the first beam information corresponding to the first measurement result, the first information is described in detail below.

[0099] (1) The first information indicates first beam information corresponding to the first measurement result.

[0100] In a possible implementation manner, the first information includes one or more first beam information corresponding to the first measurement result, and the first measurement result is calculated based on the second measurement results corresponding to the one or more first beam information.

[0101] The first measurement result is calculated based on the second measurement result corresponding to one or more first beam information, which can also be understood as: the first measurement result is obtained based on the second measurement result corresponding to one or more first beam information. In other words, the first measurement result can be determined based on the second measurement result corresponding to one or more first beam information.

[0102] Optionally, the second measurement result includes one or more of the following information: CSI, CIR, PDP, CFR. Of course, the second measurement result may also be a channel coefficient corresponding to a channel frequency domain subcarrier or a channel coefficient corresponding to each RE, etc., which is not limited here.

[0103] In a specific implementation, after the antenna array equipped with the access network device receives the reference signal from the terminal device, each antenna in the antenna array will measure and obtain a measurement result. Figure 5 As shown in the figure, taking the measurement result as a CIR sequence as an example, when the antenna array equipped with the access network device includes n antennas, the CIR sequence corresponding to the n antennas can be obtained, that is, the CIR sequence corresponding to the first antenna is h1(t), the CIR sequence corresponding to the second antenna is h2(t), and the CIR sequence corresponding to the nth antenna is h n (t). Wherein, t represents time.

[0104] If the access network device reports the measurement results measured by each antenna, it will cause high signaling overhead and lead to high network load. Therefore, the access network device can use receiver beamforming to merge the measurement results obtained by measuring each antenna in the antenna array to obtain the second measurement results corresponding to one or more first beam information. By calculating the second measurement results corresponding to the one or more first beam information, the first measurement result can be obtained (it can also be understood that the first measurement result is obtained based on the second measurement results corresponding to the one or more first beam information). The access network device only needs to report the first measurement result to the first network element, which greatly saves the overhead of reporting the channel measurement results.

[0105] The basic principle of beamforming can be expressed as follows:

[0106] h rx_m (n)=a(θ)[h1(n),h2(n),...,h N (n)] (1)

[0107] In formula (1), h rx_m (n) represents the beam vector with index value m, for example h rx_1 (n) represents the beam vector with index value 1, h rx_2 (n) represents the beam vector with index value 2. h N (n) represents the measurement result obtained by measuring the Nth antenna element, for example, h1(n) represents the measurement result obtained by measuring the first antenna element, and h2(n) represents the measurement result obtained by measuring the second antenna element. a(θ) represents the steering vector, which can be expressed as shown in formula (2).

[0108]

[0109] In formula (2), φ k Controls the angular direction of the beam. or Where d is the distance between antenna elements and λ is a constant. k There are also other forms, such as k represents the kth beam, M represents the number of antenna elements, and the present application embodiment does not limit this. The sign can be positive or negative, that is, or The embodiments of the present application are not limited thereto.

[0110] like Figure 6 As shown, taking the first measurement result as a CIR sequence as an example, the access network device can combine the measurement results obtained by measuring each antenna in the antenna array in a beamforming manner to obtain a second measurement result corresponding to the first beam information 1 (such as Fig. 7A As shown, h rx_1 (n)) and the second measurement result corresponding to the first beam information 2 (such as Figure 7B As shown, h rx_2 (n)). Among them, the first beam information 1 is the first beam information corresponding to beam 1, and the first beam information 2 is the first beam information corresponding to beam 2.

[0111] In a possible implementation manner, with respect to the case where the first measurement result is calculated based on the second measurement results corresponding to one or more first beam information, a method for calculating the first measurement result is described in detail below.

[0112] Method 1: The first measurement result includes one or more second measurement results corresponding to the first beam information.

[0113] In a specific implementation, the access network device can directly report the second measurement results corresponding to one or more first beam information. In other words, the first measurement result can be directly equal to the second measurement results corresponding to one or more first beam information without any other processing. Since the second measurement results corresponding to the one or more first beam information are obtained by merging the measurement results obtained by measuring each antenna in the antenna array using beamforming, the reporting of omnidirectional multi-antenna measurement results is avoided, and the overhead of reporting channel measurement results is saved to a certain extent.

[0114] For example, taking the second measurement result as the CIR sequence, the CIR sequence corresponding to the first beam information 1 is h rx_1 (n), the CIR sequence corresponding to the first beam information 2 is h rx_2 (n). The first measurement result can be directly h rx_1 (n) and h rx_2 (n).

[0115] Method 2: The first measurement result is obtained by performing a weighted sum operation on the second measurement results corresponding to one or more first beam information.

[0116] In a specific implementation, the access network device can weight and process the second measurement results corresponding to one or more beam information, and report the obtained measurement results (i.e., the first measurement results) to the first network element. Based on this method, the second measurement results corresponding to different first beam information can be weighted and combined before reporting, thereby further reducing the channel measurement result reporting overhead. Among them, the weight value of the second measurement result corresponding to each first beam information can be any real number, any complex number, or any vector, which is not limited here.

[0117] like Figure 7C As shown, taking the second measurement result as the CIR sequence as an example, the CIR sequence corresponding to the first beam information 1 is h rx_1 (n), the CIR sequence corresponding to the first beam information 2 is h rx_2 (n). The weight value 1 of the CIR sequence corresponding to the first beam information 1 is a, and the weight value 2 of the CIR sequence corresponding to the first beam information 2 is b. rx_1 (n) and h rx_2 (n) performing a weighted sum calculation to obtain a first measurement result. Wherein, a and b may be the same or different, and a and b may be real numbers, complex numbers or vectors. When a is equal to b, it indicates equal weight merging h rx_1 (n) and hrx_2 (n); when a and b are vectors, it means h rx_1 (n) at different points (i.e. different values ​​of n) and h rx_2 The different points in (n) are weighted and calculated.

[0118] Optionally, the first information also includes a weight value of the second measurement result corresponding to each first beam information. That is to say, in addition to merging the second measurement results corresponding to different first beam information and then reporting them, the access network device also indicates the merging method, so that after receiving the first measurement result, the first network element can determine the second measurement result corresponding to each first beam information according to the merging method.

[0119] Method three: the first measurement result is obtained by time-domain splicing of the second measurement results corresponding to one or more first beam information.

[0120] In a specific implementation, the access network device can perform time domain splicing processing on the second measurement results corresponding to one or more beam information, and report the obtained measurement results (i.e., the first measurement results) to the first network element. Based on this method, the second measurement results corresponding to different first beam information can be merged by time domain splicing and then reported, thereby further reducing the channel measurement result reporting overhead.

[0121] For example, taking the second measurement result as the CIR sequence, the CIR sequence corresponding to the first beam information 1 is h rx_1 (n), the CIR sequence corresponding to the first beam information 2 is h rx_2 (n). rx_1 (n) and h rx_2 (n) Perform time domain splicing to obtain a first measurement result.

[0122] Method 4: The first measurement result is obtained by differentiating the second measurement results corresponding to one or more first beam information.

[0123] Case 1: A difference is performed between the second measurement results corresponding to one or more first beam information.

[0124] In a specific implementation, the access network device can perform differential calculation on the second measurement results corresponding to one or more beam information, and report the obtained measurement results (i.e., the first measurement results) to the first network element. Based on this method, the second measurement results corresponding to different first beam information can be differentiated and then reported, thereby further reducing the channel measurement result reporting overhead.

[0125] Case 2: The second measurement result corresponding to one or more first beam information is differentiated from the third measurement result.

[0126] In a specific implementation, the third measurement result may be a fixed sequence or a measurement result obtained by other methods, which is not limited here. The access network device may perform differential calculation using the second measurement result and the third measurement result corresponding to one or more beam information, and report the obtained measurement result (i.e., the first measurement result) to the first network element. Based on this method, the second measurement results corresponding to different first beam information can be differentiated and then reported, thereby further reducing the channel measurement result reporting overhead.

[0127] Optionally, the first information also includes a third measurement result. That is, in addition to reporting the first measurement result, the access network device also needs to indicate the third measurement result, so that the first network element can clearly understand that the first measurement result is obtained by differentially calculating the second measurement result and the third measurement result corresponding to one or more beam information, thereby determining the second measurement result corresponding to each first beam information.

[0128] Case 3: The second measurement result corresponding to one or more first beam information is differentiated from a preset value.

[0129] In a specific implementation, the access network device can perform differential calculation using the second measurement results corresponding to one or more beam information and a preset value, and report the obtained measurement result (i.e., the first measurement result) to the first network element. Based on this approach, the second measurement results corresponding to different first beam information can be differentiated and then reported, thereby further reducing the channel measurement result reporting overhead.

[0130] Optionally, the first information also includes a preset value. That is, in addition to reporting the first measurement result, the access network device also needs to indicate the preset value, so that the first network element can clearly understand that the first measurement result is obtained by differentially calculating the second measurement result corresponding to one or more beam information and the preset value, thereby determining the second measurement result corresponding to each first beam information.

[0131] Of course, the calculation method of the first measurement result may also be a combination of the above four methods, or may be other methods, which are not limited here.

[0132] In a possible implementation, the first beam information includes one or more of the following information: a first angle value of the first beam, a first angle range of the first beam, an index value of the first beam, and an index value of a reference signal associated with the first beam.

[0133] For example, the first beam information may include: a first angle value of the first beam is 90 degrees, an index value of the first beam is 1, and an index value of a reference signal associated with the first beam is 1.

[0134] For another example, the first beam information may include: a first angle range of the first beam is 0-90 degrees, an index value of the first beam is 1, and an index value of a reference signal associated with the first beam is 1.

[0135] (2) The first information indicates first angle information corresponding to the first measurement result.

[0136] In a possible implementation manner, the first angle information includes one or more second angle values, or the first angle information includes one or more second angle ranges.

[0137] That is to say, the access network device may also directly indicate one or more second angle values ​​or second angle ranges corresponding to the first measurement result, thereby reducing the complexity of information reporting.

[0138] For example, the first information may directly indicate first angle information corresponding to the first measurement result, and the first angle information may be: the second angle value is 90 degrees.

[0139] For another example, the first information may directly indicate first angle information corresponding to the first measurement result, and the first angle information may be: the second angle range is 0-90 degrees.

[0140] In addition, for a scenario in which the first network element is only interested in channel measurement results in a certain characteristic direction or angle range, the measurement request message may include other indication information.

[0141] In a possible implementation, the measurement request message includes first indication information; the first indication information indicates second angle information corresponding to the channel information requested to be measured, or the first indication information indicates one or more second beams corresponding to the channel information requested to be measured. Based on this method, the first network element can instruct the access network device to only report the measurement results within a partial range, thereby avoiding the reporting of omnidirectional multi-antenna measurement results, which is conducive to saving the overhead of reporting channel measurement results. Of course, the angle information or angle range corresponding to the first measurement result actually reported by the access network device and the angle information or angle range corresponding to the measurement result reported by the first network element instructing the access network device to report may be the same or different. The two situations of the first indication information are specifically described below.

[0142] (1) The first indication information indicates one or more second beams corresponding to the channel information requested to be measured.

[0143] In one possible implementation, the first indication information includes information of one or more second beams; the information of the second beam includes one or more of the following information: a third angle value of the second beam, a third angle range of the second beam, an index value of the second beam, and an index value of a reference signal associated with the second beam.

[0144] In a specific implementation, the measurement request message sent by the first network element may also indicate one or more second beams corresponding to the channel information requested for measurement; after receiving the measurement request message, the access network device may report the first measurement result with reference to the indicated one or more second beams. The third angle value of the second beam and the first angle value of the first beam included in the first measurement result may be the same or different, and the third angle range of the second beam and the first angle range of the first beam included in the first measurement result may also be the same or different.

[0145] That is to say, the third angle value of the second beam or the third angle range of the second beam indicated by the first network element is only for reference for the access network device. What the access network device actually measures may be the measurement results corresponding to the one or more second beams (that is, the first angle value or the first angle range of the first beam is the same as the third angle value or the third angle range of the second beam) or the measurement results corresponding to the beam related to the one or more second beams (that is, the first angle value or the first angle range of the first beam is different from the third angle value or the third angle range of the second beam).

[0146] For example, the first indication information sent by the first network element indicates that the third angle value of the second beam corresponding to the channel information requested for measurement is 80 degrees, and the first angle value of the first beam included in the first measurement result actually reported by the access network device is 90 degrees. For another example, the first indication information sent by the first network element indicates that the third angle range of the second beam corresponding to the channel information requested for measurement is 0-80 degrees, and the first angle range of the first beam included in the first measurement result actually reported by the access network device is 0-90 degrees.

[0147] For example, the first indication information sent by the first network element indicates that the third angle value of the second beam corresponding to the channel information requested for measurement is 90 degrees, and the first angle value of the first beam included in the first measurement result actually reported by the access network device is 90 degrees. For another example, the first indication information sent by the first network element indicates that the third angle range of the second beam corresponding to the channel information requested for measurement is 0-90 degrees, and the first angle range of the first beam included in the first measurement result actually reported by the access network device is 0-90 degrees.

[0148] (2) The first indication information indicates second angle information corresponding to the channel information requested to be measured.

[0149] In a possible implementation manner, the second angle information includes one or more fourth angle values, or the second angle information includes one or more fourth angle ranges.

[0150] That is to say, the first indication information can also directly indicate one or more fourth angle values ​​or fourth angle ranges corresponding to the channel information requested for measurement, thereby reducing the complexity of the information indication; after receiving the measurement request message, the access network device can use the indicated second angle information as a reference to measure the measurement results corresponding to the second angle information or the measurement results related to the second angle information.

[0151] For example, the first information may directly indicate the second angle information corresponding to the channel information requested for measurement, and the second angle information may be: the fourth angle value is 80 degrees; the first angle value corresponding to the first measurement result actually reported by the access network device is 90 degrees. For another example, the first information may directly indicate the second angle information corresponding to the channel information requested for measurement, and the second angle information may be: the fourth angle value is 90 degrees; the first angle value corresponding to the first measurement result actually reported by the access network device is 90 degrees.

[0152] For another example, the first information may directly indicate the second angle information corresponding to the channel information requested for measurement, and the second angle information may be: the fourth angle range is 0-80 degrees; the first angle value corresponding to the first measurement result actually reported by the access network device is 0-90 degrees. For another example, the first information may directly indicate the second angle information corresponding to the channel information requested for measurement, and the second angle information may be: the fourth angle value is 0-90 degrees; the first angle value corresponding to the first measurement result actually reported by the access network device is 0-90 degrees.

[0153] For the first beam mentioned above, in a possible implementation, the first beam is a diameter-level beam. Of course, the first beam can also be a signal-level beam, which is not limited here. When the first beam is a diameter-level beam, the energy of a certain diameter can be maximized; when the first beam is a signal-level beam, the energy of the entire channel can be maximized. Similarly, for the second beam mentioned above, the second beam can also be a diameter-level beam or a signal-level beam, which is not limited here.

[0154] In a possible implementation, the first information includes path information, which is information about the path associated with the beam information. Each beam information is associated with a path, and when reporting the first measurement result and the beam information, the access network device may further report information about the path associated with each beam information.

[0155] like Figure 6 As shown, the first measurement result includes the second measurement result corresponding to beam information 1 and the second measurement result corresponding to beam information 2. Beam 1 is associated with path 1 (LOS path), and beam 2 is associated with path 2 (NLOS path). Therefore, the first information can also include information about path 1 and information about path 2.

[0156] Optionally, the path information includes one or more of the following information: path identification, path name, and path-associated reflector information. The path identification may be a predefined path identity or a randomly generated identity, which is not limited here. The path name may be the first path, the second path, the strongest path, the weakest path, the farthest path, the closest path, etc., which is not limited here. The path-associated reflector information may be reflector 1, reflector 2, reflective surface 1, reflective surface 2, etc., which is not limited here.

[0157] For example, the information of path 1 may include: the path identifier is 1, the path name is the first path, and the reflector information associated with the path is reflector 1.

[0158] exist Figure 4 In the described method, the first network element sends a measurement request message to the access network device, and the access network device reports the first measurement result and the first information to the first network element according to the measurement request message. The first information indicates the angle value or angle range corresponding to the first measurement result. That is to say, after the access network device receives the measurement request message from the first network element, it measures the reference signal from the terminal device according to the measurement request message to obtain the first measurement result. The first measurement result may be a measurement result in a certain direction or within a certain range. Therefore, in addition to reporting the first measurement result, the access network device also needs to indicate the angle value or angle range corresponding to the first measurement result. Since the access network device only reports the measurement results in one or more directions, or the access network device only reports the measurement results within a certain range, it is possible to avoid reporting the measurement results of omnidirectional multi-antennas, which is conducive to saving the overhead of reporting channel measurement results.

[0159] Figure 8 FIG. 1 is a flow chart of another information reporting method provided in an embodiment of the present application. Figure 8 As shown, the information reporting method includes the following steps S801 and S802. Figure 8 The method execution subject shown may be the terminal device and the first network element mentioned above. Or, Figure 8 The execution entity of the method shown may be a chip in a terminal device and a chip in a first network element, which is not limited in the embodiments of the present application. Figure 8 The method is described by taking the terminal device and the first network element as the execution subject. In addition, the first network element may be an independent device or integrated in the access network device, which is not limited here. The embodiment of the present application is described by taking the first network element as an independent device as an example.

[0160] S801. A first network element sends a measurement request message to a terminal device. Correspondingly, the terminal device receives the measurement request message from the first network element.

[0161] In the embodiment of the present application, the measurement request message is used to request the measurement of channel information. The specific implementation of step S801 can refer to the specific implementation of step S401 above, the only difference is that the execution subject has changed, that is, the access network device is changed to the terminal device, and the specific implementation of step S801 is not repeated here.

[0162] S802: The terminal device reports the first measurement result and the first information to the first network element according to the measurement request message. Correspondingly, the first network element receives the first measurement result and the first information from the terminal device.

[0163] In an embodiment of the present application, the first information indicates first angle information or first beam information corresponding to the first measurement result.

[0164] Optionally, the terminal device reports the first measurement result and the first information to the first network element through the access network device according to the measurement request message. Correspondingly, the first network element receives the first measurement result and the first information from the terminal device through the access network device. In other words, the terminal device may also transparently transmit the first measurement result and the first information to the first network element through the access network device.

[0165] Among them, the specific implementation method of step S802 can refer to the specific implementation method of the above-mentioned step S402. The only difference is that the execution subject has changed, that is, the access network device is changed to a terminal device. The specific implementation method of step S802 will not be repeated here.

[0166] exist Figure 8 In the described method, the first network element sends a measurement request message to the terminal device, and the terminal device reports the first measurement result and the first information to the first network element according to the measurement request message. The first information indicates the angle value or angle range corresponding to the first measurement result. That is to say, after the terminal device receives the measurement request message from the first network element, it measures the reference signal according to the measurement request message to obtain the first measurement result. The first measurement result may be a measurement result in a certain direction or within a certain range, so in addition to reporting the first measurement result, the terminal device also needs to indicate the angle value or angle range corresponding to the first measurement result. Since the terminal device only reports the measurement results in one or more directions, or the terminal device only reports the measurement results within a certain range, it is possible to avoid reporting the measurement results of omnidirectional multi-antennas, which is conducive to saving the overhead of reporting channel measurement results.
