Information sending and receiving methods and devices

Technical field

The embodiments of this application relate to the field of communication technology.

Background technique

As low-frequency spectrum resources become scarce, millimeter wave frequency bands can provide larger bandwidth and become an important frequency band for 5G NR (New Radio) systems. Due to its shorter wavelength, millimeter waves have different propagation characteristics from traditional low-frequency bands, such as higher propagation loss, poor reflection and diffraction performance, etc. Therefore, larger antenna arrays are usually used to form shaped beams with greater gain, overcome propagation losses, and ensure system coverage. The 5G NR standard designs a series of solutions for beam management such as beam scanning, beam measurement, beam reporting, and beam indication. However, when the number of transmitting and receiving beams is relatively large, the load and delay of the system will be greatly increased.

With the development of artificial intelligence (AI) technology, applying artificial intelligence technology to the physical layer of wireless communications to solve the difficulties of traditional methods has become a current technical direction. For beam management, the use of AI models to predict spatially optimal beam pairs based on the results of a small number of beam measurements can significantly reduce system load and delay.

Figure 2 is a schematic diagram of transmitting beams and receiving beams in the communication system according to various embodiments of the present application. As shown in Figure 2, in the communication system 100, taking the downlink channel as an example, the network device 101 may have M1 downlink transmit beams DL TX, and the terminal device 102 may have N1 downlink receive beams DL RX.

To address the above problems, embodiments of the present application provide an information transceiving method and device, which will be described below with reference to the accompanying drawings and embodiments.

Embodiments of the first aspect

The embodiment of the present application provides a method for sending and receiving information, which will be explained from the terminal device side.

401. The terminal device receives the reported configuration information sent by the network device;

402. The terminal device sends beam measurement reporting information to the network device.

It is worth noting that the above Figure 4 only schematically illustrates the embodiment of the present application, but the present application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and some other operations can also be added or some of them reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 4 above.

In some embodiments, an AI model for beam prediction is deployed in a network device. The AI model is used to predict the optimal beam pair through a small number of beam pair measurement results. The input parameter of the AI model is the RSRP of some beam pairs (Reference Signal Receiving Power, reference signal receiving power) value, can also be the SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio) value of some beam pairs. The physical quantity of the output parameter is the RSRP or SINR of all beam pairs, Figure 5 is a schematic diagram of the transmitting beam, receiving beam and AI model in the embodiment of the present application. As shown in Figure 5, for example, there are 12 downlink transmitting beams and 8 downlink receiving beams, totaling 96 beam pairs. Through configuration, the UE only measured the RSRP of 24 beam pairs (6 downlink transmit beams and 4 downlink receive beams). At this time, the input parameter dimension of the AI model is 24, the physical quantity is RSRP or SINR, the output parameter dimension is 96, the physical quantity is also RSRP or SINR, and the optimal beam pair can be selected from the prediction results.

In order to use this AI model for beam prediction, the AI model deployed on the network device side needs to know the measurement results of some beam pairs, as well as the downlink transmit beam and downlink receive beam in the beam pair associated with the measurement results. To this end, in this paper In the application embodiment, the above-mentioned reporting configuration information includes enabling and disabling information for indicating downlink receiving beam reporting and/or beam pair information of the reported downlink transmitting beam and downlink receiving beam; and/or, the beam measurement reporting information includes and The downlink receive beam indication information corresponding to the measurement result, or the beam measurement report information does not include the downlink transmit beam indication information and/or the downlink receive beam indication information corresponding to the measurement result.

Through the above embodiments, the reporting configuration information sent by the network device to the terminal device includes the enabling and disabling information for indicating the reporting of the downlink receiving beam and/or the beam pair information of the reported downlink transmitting beam and the downlink receiving beam. Therefore, the terminal The device can report the beam measurement results according to the corresponding rules based on the reported configuration information, so that the AI model can learn the downlink receiving beam corresponding to the beam measurement result, and can effectively use the AI model to predict the optimal beam pair, which can greatly reduce the cost of beam measurement. Resulting system load and delays.

Through the above embodiments, the beam measurement reporting information sent by the terminal device to the network device includes the downlink receiving beam indication information corresponding to the measurement result. Therefore, the AI model can learn the downlink receiving beam corresponding to the beam measurement result, and can effectively use AI Models are used to predict the optimal beam pairs, which can greatly reduce the system load and delay caused by beam measurement.

Details below.

In some embodiments, the network device configures the parameters required for reporting through the reporting configuration information, and notifies the terminal device that in the existing reporting configuration information, the parameters that the network device needs to configure include: report quantity (Report Quantity), measurement Constraint configuration, codebook configuration, group-based reporting configuration, reporting cycle, etc., for example, when beam management is required, the reporting amount is a combination of the following parameters: CRI-RSRP/SINR (CSI-RS-based beam management) or SSBRI- RSRP/SINR (SSB-based beam management), the terminal equipment performs beam measurement on the reference signal and sends beam measurement reporting information according to the reporting configuration information. The existing beam measurement reporting information includes the reporting amount CRI- configured by the reporting configuration information. RSRP/SINR or SSBRI-RSRP/SINR, that is to say, it includes the beam measurement result RSRP/SINR and the CRI/SSBRI associated with the measurement result. The CRI/SSBRI can implicitly indicate the downlink transmission beam.

On the one hand, in the embodiment of the present application, in the existing reporting configuration information, new enabling and disabling information for instructing downlink receiving beam reporting is used, and the disabling information is used to instruct the terminal device to enable reporting of downlink receiving beam indication information. When , the beam measurement reporting information adds downlink receiving beam indication information corresponding to the measurement results.

In some embodiments, the enable and disable information can be represented by a 1-bit information element. When the bit value is 1, it indicates that the reporting of downlink receive beam indication information is enabled (for example, using a new reporting format). When the value is 0, it means that the reporting of downlink receiving beam indication information is prohibited (for example, using the reporting format in Table 1), and vice versa; or, when the reported configuration information includes the enable and disable information, it means that the downlink receiving beam is enabled. Reporting of indication information (for example, using a new reporting format). When the use disabling information is defaulted (omitted), it means that reporting of downlink receiving beam indication information is prohibited (for example, using the reporting format as shown in Table 1). This is no longer the case. An example.

In some embodiments, the downlink receive beam indication information may be an explicit or implicit indication. For example, the downlink receive beam indication information is downlink receive beam identification information or downlink receive beam angle information or an uplink transmit beam indication corresponding to the downlink receive beam. The information or the first logical index of the downlink receive beam among all the downlink receive beams in the training set or the second logical index of the beam pair where the downlink receive beam is located among all the beam pairs in the training set.

For example, the downlink reception beam indication information is the downlink reception beam identification information, including a first identification of the horizontal direction beam sequence number and a second identification of the vertical direction beam sequence number, or a third identification including the beam sequence number. Among them, if the downlink receiving beam is a 3D beamforming, that is, the beam can contain two dimensions: horizontal and vertical, then it can be sequentially numbered in the horizontal and vertical directions (taking 8 downlink receiving beams as an example, as shown in Figure 6 shown), therefore, the downlink receiving beam identification information includes the first identification of the horizontal direction beam sequence number and the second identification of the vertical direction beam sequence number. Alternatively, sequential numbering can also be performed in two dimensions (taking 8 downlink receiving beams as an example, as shown in Figure 7). Therefore, the downlink receiving beam identification information includes the third identification of the beam sequence number. It should be noted that Figure 6 In Figure 7, 8 downlink receiving beams are taken as an example. The horizontal direction and then the vertical direction are sequentially numbered. However, the embodiment of the present application is not limited to this. It can also be the vertical direction first and then the horizontal direction, or other numbers. Downlink reception beams are not given here. The above-mentioned first identifier, second identifier, and third identifier may be represented by a binary code of predetermined bits. Table 2 is a schematic diagram of the beam measurement reporting information format in the embodiment of the present application. As shown in Table 2, the difference from Table 1 is that in the beam measurement reporting information, measurement results #1, #2, #3, #4 associated downlink receive beam identification information RX Beam ID #1, #2, #3, #4 to indicate the downlink receive beam associated with the measurement results.

Table 2

For example, the downlink receiving beam indication information is the downlink receiving beam angle information, including horizontal direction beam angle information and vertical direction beam angle information. Among them, if the downlink receive beam is a 3D beamforming, that is, the beam can contain two dimensions: horizontal and vertical, then the horizontal angle and vertical angle of the downlink receive beam in space can be used to uniquely indicate the 8 downlink Taking the receiving beam as an example, Figure 8 is an example diagram of the downlink receiving beam angle information. As shown in Figure 8, it is assumed that there are 2 angles in the vertical direction (e.g. 45 degrees, 135 degrees) and 4 angles in the horizontal direction (e.g. - 67 degrees, -22 degrees, 22 degrees, 67 degrees), therefore, the downlink receiving beam identification information includes horizontal direction beam angle information and vertical direction beam angle information. It should be noted that in Figure 8, there are 8 downlink receiving beams and 2 in the vertical direction. Angle, four angles in the horizontal direction are taken as an example, but the embodiment of the present application is not limited to this, and no examples are given here. The above-mentioned horizontal direction beam angle information and vertical direction beam angle information can be represented by binary encoding of predetermined bits. Table 3 is a schematic diagram of the beam measurement reporting information format in the embodiment of the present application. As shown in Table 3, the difference from Table 1 is that in the beam measurement reporting information, measurement results #1, #2, #3, #4 associated downlink receive beam angle information RX Beam angle #1, #2, #3, #4 to indicate the downlink receive beam associated with the measurement results.

table 3

The above uses an explicit way to indicate the downlink receiving beam, but this application is not limited to this, and the downlink receiving beam can also be indicated in an implicit way.

For example, the downlink receive beam indication information may be the uplink transmit beam indication information corresponding to the downlink receive beam. As shown in Figure 3, utilizing the reciprocity in the wireless channel space, the direction of the uplink transmit beam and the direction of the downlink receive beam are basically the same. , therefore, the uplink transmit beam corresponding to the downlink receive beam can be used to implicitly indicate the downlink receive beam. The uplink transmit beam indication information includes the SRS resource indication (SRI) or the random access preamble index (PRACH Preamble index), that is, for The uplink transmit beam can be indicated by SRI or PRACH preamble index. Table 4 is a schematic diagram of the beam measurement reporting information format in the embodiment of the present application. As shown in Table 4, the difference from Table 1 is that in the beam measurement reporting information, measurement results #1, #2, #3, #4 associated uplink transmit beam indication information SRI/PRACH Preamble index #1, #2, #3, #4 to indicate the downlink receive beam associated with the measurement results.

In other words, The downlink reception beam indicated by the downlink reception beam indication information includes all downlink reception beams, and the implementation of the downlink reception beam indication information is as described above.

In some embodiments, during the inference phase of the AI model, the terminal device only reports the measurement results of some beam pairs, and uses the measurement results of some beam pairs to use the trained AI model to infer the measurement results of all beam pairs, and then Obtain the optimal beam pair. When the terminal device reports the measurement results in the beam measurement reporting information, it needs to report the information of the downlink receiving beams associated with the measurement results of some beam pairs to the network device. That is to say, the downlink receiving beams indicated by the downlink receiving beam indication information Including the end of partial downlink reception in all downlink reception beams, the implementation of the downlink reception beam indication information is as described above.

In addition, in the reasoning stage of the AI model, the downlink receive beam indication information can also be the first logical index of the downlink receive beam among all downlink receive beams in the training set or the second logical index of the beam pair where the downlink receive beam is located among all the beam pairs in the training set.

Table 6

In some embodiments, as mentioned above, the reporting configuration information may also include beam group-based reporting parameters (groupBasedBeamReporting), when beam group-based reporting is configured to be disabled, and when indicating the enablement of downlink receive beam reporting When the disabling information is configured to be enabled, the beam measurement reporting information may refer to the previous embodiment, when the beam group-based reporting is configured to be enabled, and when the enabling disabling information indicating downlink receiving beam reporting is configured to be enabled , the downlink receive beam indication information also includes the index of the beam group, that is, the index of the beam group is used in combination with the downlink receive beam identification information/downlink receive beam angle information/uplink transmit beam indication information corresponding to the downlink receive beam/first The logical index/second logical index uniquely indicates the downlink receiving beam.

As shown in Table 7, the difference from Table 1 is that in the beam measurement reporting information, measurement results #1, #2, #3, #4 is associated with the downlink receive beam identifiers #1, #2, #3, and #4, and also adds the index of the beam group where the downlink receive beam is located. In addition, the measurement results and SSBRI/CRI also include the index of the corresponding beam group.

Table 7

In some embodiments, the downlink receive beam identification information in Table 7 can also be replaced by downlink receive beam angle information/uplink transmit beam indication information corresponding to the downlink receive beam/first logical index/second logical index.

In some embodiments, the beam measurement reporting information may include all beam groups and all downlink receiving beam indication information within the beam groups, or may include partial beam groups and all downlink receiving beam indication information within the beam groups. .

In the above embodiment, the beam measurement reporting information includes downlink transmit beam indication information (such as SSBRI/CRI/third logical index/second logical index) corresponding to the measurement results. Optionally, it may not include the information corresponding to the measurement results. Corresponding downlink transmission beam indication information.

For example, when the reference signal resource for beam measurement is configured as repetition (repetition on), it means that the downlink transmission beam is fixed, and the network device knows the fixed downlink transmission beam. Therefore, the beam measurement reporting information may not include the information corresponding to the measurement result. Downlink transmission beam indication information.

As mentioned before, in the inference phase of the AI model, only the measurement results of a small number of beam pairs are reported. Optionally, in addition to the above-mentioned enable and disable information, the reported configuration information can also include the reported downlink transmit beams and downlink receive beams. The beam pair information is used to indicate the small number of beam pairs. The terminal device can measure the beam pairs configured in the reported configuration information and send the beam measurement reporting information to the network device. The implementation of the beam measurement reporting information is as before The above will not be repeated here. The beam pair information includes indication information of the downlink transmit beam and the downlink receive beam, where two indication information can be used to indicate the downlink transmit beam and the downlink receive beam respectively. For example, the beam pair information can be SSBRI/CRI/third logical index +Downlink receive beam identification information/Downlink receive beam angle information/Uplink transmit beam indication information corresponding to the downlink receive beam/First logical index. Alternatively, one indication information may be used to indicate the downlink transmit beam and the downlink receive beam together. For example, the beam pair information may be the second logical index. The implementation of the indication information is as described above and will not be described again here.

On the one hand, the reported configuration information includes the reported beam pair information of the downlink transmit beam and the downlink receive beam. When the beam pair information indicates multiple beam pairs, in the beam measurement reporting information, the multiple beam pairs correspond to The measurement information (measurement results) is arranged in a predetermined order, for example, according to the configuration order of the multiple beam pairs configured in the reported configuration information, and the measurement results are reported, but the embodiment of the present application is not limited to this, therefore, The beam measurement reporting information does not need to include downlink transmit beam indication information and downlink receive beam indication information corresponding to the measurement results. The network device can learn which beam pair each measurement result corresponds to based on the reported measurement information arranged in a predetermined order. Since the beam pair is a parameter configured by the network device in the reported configuration information, the network device (AI model deployed on the network device) can determine the downlink transmit beam and downlink receive beam corresponding to the beam pair.

For example, referring to Figure 9, the beam pair information included in the reported configuration information is (1,1), (1,5), (7,1), (7,5) (here the beam pair information is the third logical index +Example of the first logical index, the embodiment of the present application is not limited to this), the corresponding measurement results are RSRP#1, RSRP#2, RSRP#3, RSRP#4 respectively. Table 8 is the embodiment of the present application The format of the medium-beam measurement reporting information is shown in Table 8. The difference from Table 1 is that the beam measurement reporting information does not include the SSBRI/s associated with the measurement results RSRP #1, #2, #3, and #4. CRI #1, #2, #3, #4 are different from those in Tables 2 to 7 in that they do not need to include the downlink receive beam indication information associated with the measurement results RSRP #1, #2, #3, #4. , in the beam measurement reporting information, RSRP#1, RSRP#2, RSRP#3, and RSRP#4 are arranged in this order. The network device can learn that RSRP#1 corresponds to the beam pair (1,1), RSRP#2 corresponds to the beam pair (1,5), RSRP#3 corresponds to the beam pair (7,1), and RSRP#4 corresponds to the beam pair (7,5 ), therefore, the network device (AI model deployed on the network device) can determine the downlink transmit beam and the downlink receive beam corresponding to the beam pair. This implementation mode is applicable to the training phase and inference phase of AI, and the embodiments of the present application are not limited to this.

Table 7 takes 4 beam groups with 2 beams in each group as an example. Table 8 takes 4 beam pairs as an example, but the number of beam pairs or beam groups can be less than 4 (at least 1) or more than 4. This application does not use this as a quantity limit, and the number can depend on the terminal. The capabilities of the device or the configuration of the network device. In addition, in Tables 1 to 8, except for the first beam, which uses the absolute RSPR value, the other beams use the difference value from the RSRP of the first beam. However, the embodiment of the present application does not use this as a limitation. All reported beams can use absolute RSRP values. In addition, in the measurement layer 1 RSRP, the measurement quantity can also be replaced by SINR. This application is not limited to this, and can be specifically determined according to the reporting quantity parameter in the reporting configuration information configured by the network device. In addition, as shown in Tables 1 to 8, the beam measurement reporting information may also include a CSI report number (CSI report#n). For specific implementation methods, reference may be made to the existing technology, which will not be described again here.

The beam pair information may not be included in , and the beam measurement reporting information includes measurement information (measurement results) corresponding to all beam pairs, and the measurement results of all beam pairs are arranged in a predetermined order.
