Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a signal transmission method, a signal reception method, and a communication device. Background Technology

[0002] In related technologies, Radio Resource Control (RRC) combined with bitmaps is mainly used to indicate whether to send an SSB (or enable an SSB) at each SSB occasion in the Synchronization Signal and PBCH block (SSBburst set).

[0003] In some scenarios, it may be necessary to obtain relevant information based on disabled SSBs in the SSB burst set, such as complete beam quality information and beam gain information. In this regard, related technologies can update the bitmap mapping relationship through RRC signaling to solve the problem of untransmitted or disabled SSBs in the SSB burst set. However, this method not only has the problem of slow parameter updates, but also, since the SSB occasion is related to the content of the System Information Block (SIB), updating the bitmap mapping relationship will inevitably require changing the system information, which will affect other users in the cell.

The technical solutions provided in this application embodiment will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0032] like Figure 2 The diagram shown is a flowchart illustrating a signal transmission method 200 provided in an exemplary embodiment of this application. This method can be, but is not limited to, executed by a first communication device, specifically by hardware and / or software installed in the first communication device. In this embodiment, the method 200 may include at least the following steps.

[0033] S210, the first communication device sends a target signal to the second communication device.

[0034] The first communication device and the second communication device can be network-side devices, such as base stations, or various combinations of terminals or auxiliary network central units. For example, the first communication device can be a terminal and the second communication device can be a network-side device; or, the first communication device can be a network-side device and the second communication device can be a terminal; or, both the first and second communication devices can be network-side devices; or, both the first and second communication devices can be terminals; or, the first communication device can be an auxiliary network central unit and the second communication device can be a network-side device; or, the first and second communication devices can interact through an auxiliary network central unit, which is a unit used for information exchange.

[0035] In this embodiment, the target signal is associated with a first SSB, and the target signal is used for the verification of the target AI model and / or the prediction of target beam-related information. The first SSB is at least a portion of the disabled SSBs in the SSB burst set. The SSB burst set may be, but is not limited to, configured in the second communication device by the network side. For the disabled SSBs in the SSB burst set, the first communication device can determine them through signaling interaction, for example, through bitmap mapping, explicit indication, implicit indication, etc.

[0036] It is understood that in this embodiment, by associating the target signal with the first SSB, that is, associating the target signal with at least a portion of the disabled SSBs in the SSB burst set, when it is necessary to predict target beam-related information (such as beam quality-related information, beam gain-related information, beam identification-related information, beam angle-related information, etc.) and / or perform target AI model verification based on the disabled SSBs in the SSB burst set, the relevant information of the target signal associated with it can be used to replace (or substitute) the relevant information of the disabled SSBs in the SSB burst set for prediction and / or verification. Thus, on the one hand, it can avoid the problem of slow parameter updates and impact on other users in the cell when updating bitmap mapping relationships through RRC signaling in related technologies. On the other hand, it can also ensure the reliability and stability of the verified first AI model, or ensure the reliability of the predicted target beam-related information.

[0037] Based on this, as a possible implementation, the target signal may include at least one of the following: Channel State Information Reference Signal (CSI-RS), Sounding Reference Signal (SRS), Positioning Reference Signal (PRS), Tracking Reference Signal (TRS), Demodulation Reference Signal (DMRS), and SSB. It should be noted that, considering that during signal transmission, the SSB in the SSB burstset is generally located on the first half-frame of a radio frame, when the target signal is an SSB, the target signal may be located on the second half-frame of a radio frame.

[0038] The target AI model can be a first AI model configured in the first communication device, a second AI model configured in the second communication device, or an AI model configured in other communication devices besides the first and second communication devices. Of course, for devices other than the second communication device, the second communication device needs to at least feed back relevant information about the measured target signal. It is understood that the model "verification" mentioned in this application can also be understood as model verification, adjustment, fine-tuning, updating, etc., without limitation. The target AI model (such as the first AI model and second AI model mentioned later) can be a neural network, decision tree, support vector machine, Bayesian classifier, etc., without limitation. Of course, the first AI model and the subsequent second model can be the same or different, or the target AI model to be verified can be the same or different from the AI ​​model used for target beam information prediction.

[0039] In this embodiment, by sending the target signal associated with the disabled SSB in the SSB burst set, on the one hand, it can ensure the normal acquisition of information such as beam quality-related information and beam gain-related information, thus ensuring the performance of the communication system; on the other hand, it can also avoid the problem of slow parameter updates and the impact on other users in the cell when updating the bitmap mapping relationship through RRC signaling in related technologies.

[0040] like Figure 3 The diagram shown is a flowchart illustrating a signal transmission method 300 provided in an exemplary embodiment of this application. This method can be, but is not limited to, executed by a first communication device, specifically by hardware and / or software installed in the first communication device. In this embodiment, the method 300 may include at least the following steps.

[0041] S310, the first communication device sends a target signal to the second communication device.

[0042] The target signal is associated with a first SSB, and the target signal is used for the verification of the target AI model and / or the prediction of target beam-related information. The first SSB is at least a portion of the SSBs that are not enabled in the SSB burst set.

[0043] It is understood that, in addition to referring to the relevant description in method embodiment 200, as one possible implementation of S310, the first communication device sending the target signal to the second communication device can be determined autonomously by the first communication device or triggered by the second communication device. For example, assuming it is triggered by the second communication device, then the second communication device can send a first request to the first communication device, and the first communication device, upon receiving the first request from the second communication device, sends the target signal to the second communication device.

[0044] Optionally, when the second communication device requests the first communication device to send the target signal via the first request, it can make the request directly or indirectly. For example, the direct request can be made by directly requesting the first communication device to send the target signal through signaling interaction; the indirect request can be made by feeding back relevant information, such as verification-related information of the target AI model (i.e., information characterizing the performance of the AI ​​model), through signaling, to implicitly request the first communication device to send the target signal.

[0045] Of course, regardless of the triggering method by which the first communication device sends the target signal to the second communication device, the association method when the target signal is associated with the first SSB can be implemented in an explicit or implicit manner. For example, in one implementation, the association method when the target signal is associated with the first SSB may include at least one of the following (11)-(17).

[0046] (11) The beam information of the target signal is associated with the first SSB.

[0047] It is worth noting that the beam information mentioned in this application can be understood as spatial relation information, spatial domain transmission filter information, spatial filter information, Transmission Configuration Indicator state (TCI state) information, quasi-co-location (QCL) information, QCL parameters, beam association relationships, etc. Downlink beam information is typically represented using TCI state information and QCL information, while uplink beam information is typically represented using spatial relation information.

[0048] (12) The target signal is associated with the index of the first SSB.

[0049] (13) The target signal is configured with the index of the first SSB.

[0050] (14) The first bitmap indicates the association between the target signal and the index of the first SSB.

[0051] Optionally, the first bitmap may be a newly introduced bitmap specifically designed to indicate the association between the target signal and the index of the first SSB.

[0052] For example, assuming the target signal is a CSI-RS, and the SSB burst set contains 8 SSBs, of which 6 SSBs are enabled, i.e., the bitmap corresponding to the SSB burst set is 11001111, then the first communication device can additionally configure two CSI-RSs, and the first bitmap corresponding to the CSI-RS is 00110000, indicating that the two CSI-RSs are associated with the third and fourth SSBs; or, an additional CSI-RS1 and CSI-RS2 can be configured, with the first bitmap corresponding to CSI-RS1 being 10 and the first bitmap corresponding to CSI-RS2 being 01, indicating that it is associated with the fourth SSB. In this way, the association relationship between the target signal and the index of the first SSB is indicated.

[0053] (15) The length of the first bitmap is the same as the length of the second bitmap corresponding to the SSB burst set. The second bitmap corresponds to the SSB burst set and is used to indicate whether each SSB in the SSB burst set is enabled or disabled.

[0054] In one implementation, the bit in the first bitmap corresponding to the enable bit in the second bitmap within the SSB burst set should indicate a disabled state. For example, if the first bit of the second bitmap within the SSB burst set is 1, it indicates that the corresponding SSB is enabled; if the first bit of the second bitmap is 0, it indicates that the corresponding SSB is disabled.

[0055] (16) The length of the first bitmap is consistent with the number of disabled bits indicated by the second bitmap, that is, the length of the first bitmap is consistent with the number of disabled bits (i.e., disabled SSBs) indicated in the second bitmap of the SSB burst set. For example, the number of "0" bits in the second bitmap of the SSB burst set is consistent with the total number of bits in the first bitmap, wherein the SSBs corresponding to the "0" bits are disabled.

[0056] (17) Associate the first indication information with the index of the first SSB. The first indication information corresponds to the target signal. For example, assuming the first indication information is a 1-bit information, such as "0" or "1", the first communication device is additionally configured with two CSI-RS (i.e., target signals), namely CSI-RS1 and CSI-RS2. CSI-RS1 corresponds to "0" and CSI-RS2 corresponds to "1". There are a total of 8 SSBs in the SSB burst set, of which 6 SSBs are enabled. That is, the bitmap corresponding to the SSB burst set is 11001111. Then, associate "0" with the index of the third SSB, that is, associate the third SSB with CSI-RS1, and associate "1" with the index of the fourth SSB, that is, associate the fourth SSB with CSI-RS2.

[0057] Of course, in addition to the association methods described in (11)-(17) above, in one implementation, the target signal can also be directly associated with the first SSB, such as without being associated with any beam information.

[0058] In addition, in another implementation, the target signal may satisfy at least one of the following (21)-(27).

[0059] (21) The number of target signals is not greater than (or less than / equal to) the number of disabled SSBs in the SSB burst set. For example, assuming the number of disabled SSBs in the SSB burst set is N, and the number of target signals is X, then X is less than or equal to N, and X and N are integers greater than or equal to 0.

[0060] (22) The bandwidth of the target signal is related to the bandwidth of the first SSB; for example, the bandwidth of the target signal is equal to the bandwidth of the first SSB.

[0061] (23) When there are multiple configurable bandwidths of the target signal, the bandwidth of the target signal is equal to the minimum bandwidth among the multiple configurable bandwidths.

[0062] (24) The power control parameters of the target signal are related to the power control parameters of the first SSB. The power control parameters are used to adjust the transmission power. In this embodiment, the relationship between the power control parameters of the target signal and the power control parameters of the first SSB can be that the power control parameters of the target signal are consistent with the power control parameters of the first SSB.

[0063] (25) The beam gain information of the target signal is consistent with the beam gain information of the first SSB.

[0064] It can be understood that the beam gain information of the target signal being consistent with the beam gain information of the first SSB is what the second communication device expects.

[0065] It is worth noting that, in this embodiment, the beam gain-related information is used to characterize the gain-related information of the beam and / or antenna, including but not limited to at least one of the following: antenna relative gain (in dBi), effective irradiated power (EIRP), beam angle gain, beam angle gain spectrum (that is, the gain of a beam relative to different angles, including complete or partial gain spectrum information), EIRP corresponding to each beam angle, main lobe angle, side lobe angle, number of side lobes, side lobe distribution, number of antennas, horizontal coverage of beam scanning, vertical coverage of beam scanning, 3dB width, 6dB width, etc.

[0066] (26) When the target signal is a periodic or semi-continuous reference signal, the period of the target signal is greater than or equal to the period of the first SSB.

[0067] (27) The transmission power of the target signal is related to the transmission power of the first SSB. Specifically, the transmission power on each resource corresponding to the target signal (e.g., per resource element, per RE) can be the same as the transmission power on each resource corresponding to the first SSB.

[0068] In this scenario, as one implementation, the feedback type of the CSI report associated with the target signal can include None or full feedback. Specifically, when the feedback type of the CSI report associated with the target signal is full feedback, the second communication device needs to feed back all relevant information about the target signal and the relevant information about the enabled SSBs in the SSB burst set to the first communication device.

[0069] Optionally, the feedback information corresponding to the full feedback may include at least one of the following: Channel State Information Resource Indicator Reference Signal Received Power (CSI-RS), Synchronization Block Index Reference Signal Received Power (SSB-Index-RSRP), CRI-Signal-to-Noise and Interference Ratio (SINR), and SSB-Index-SINR. That is, taking the target signal as an example, when the second communication device feeds back relevant information of the target signal to the first communication device based on the full feedback method, it may feed back at least one of the following: CRI-RSRP, SSB-Index-RSRP, CRI-SINR, and SSB-Index-SINR corresponding to the target signal.

[0070] Of course, considering that after configuring the SSB burst set, the first communication device can periodically send SSBs, or it can additionally trigger the transmission of SSBs in the SSB burst set through signaling, that is, when the target signal is non-periodic, the first communication device can trigger the transmission of the second SSB at the same time as triggering the transmission of the target signal, so as to improve the efficiency of information acquisition (such as beam quality related information). In this regard, as one possible implementation, the first communication device can also send a second request to the second communication device, the second request being used to trigger the second communication device to monitor the target signal and / or the second SSB.

[0071] S320, the first communication device receives the first information sent by the second communication device.

[0072] The first information includes at least one of the following: information related to the target signal, information related to the first SSB, and information related to the second SSB. The second SSB is at least a portion of the enabled SSBs in the SSB burst set. It should be noted that, taking the target signal as an example, when there are multiple target signals, to save signaling overhead and improve transmission efficiency, the second communication device may only feed back information related to a portion of the multiple target signals. The feedback of information related to the first SSB and the second SSB is similar to that of the target signal and is not limited here.

[0073] Optionally, the relevant information of the target signal may include at least one of the following: beam quality-related information, beam identification-related information, beam angle-related information, and beam gain-related information. The beam quality-related information mentioned in this application refers to information characterizing beam quality, which may include, but is not limited to, Layer 1 (L1)-SINR, L1-RSRP, L1-Reference Signal Received Quality (RSRQ), L3-SINR, L3-RSRP, and L3-RSRQ.

[0074] Correspondingly, the relevant information of the first SSB may also include at least one of the following: beam quality information, beam identification information, beam angle information, and beam gain information corresponding to the first SSB. The relevant information of the second SSB includes at least one of the following: beam quality information, beam identification information, beam angle information, and beam gain information corresponding to the second SSB.

[0075] In this embodiment, the feedback of the first information ensures that the first communication device and the second communication device have a consistent understanding of the relevant information of the target signal, the relevant information of the second SSB, and the relevant information of the first SSB.

[0076] It is worth noting that when the feedback type of the CSI report associated with the target signal is full feedback and the CSI report is associated with the second SSB, the second communication device can feed back the first information based on the full feedback method.

[0077] S330, associate the relevant information of the target signal with the relevant information of the first SSB.

[0078] The first communication device can associate the relevant information of the target signal with the relevant information of the first SSB in various ways. For example, the index of the relevant information of the first SSB can be configured in the relevant information of the target signal; or a mapping relationship can be established between the relevant information of the target signal and the relevant information of the first SSB, etc., without limitation. It can be understood that by associating the relevant information of the target signal with the relevant information of the first SSB, the relevant information of the target signal can be used to replace the relevant information of the first SSB for the verification of the target AI model and / or the prediction of the target beam relevant information.

[0079] In this embodiment, by providing feedback on the first information and associating the relevant information of the target signal with the relevant information of the first SSB, on the one hand, it can ensure the consistency of understanding between the first communication device and the second communication device regarding the relevant information of the target signal, the relevant information of the second SSB, and the relevant information of the first SSB. On the other hand, it can also improve the convenience and efficiency of retrieving the relevant information of the target signal when using the relevant information of an disabled SSB.

[0080] like Figure 4 The diagram shown is a flowchart illustrating a signal transmission method 400 provided in an exemplary embodiment of this application. This method 400 can be executed by, but is not limited to, a first communication device, specifically by hardware and / or software installed in the first communication device. In this embodiment, the method 400 may include at least the following steps.

[0081] S410, the first communication device sends a target signal to the second communication device.

[0082] The target signal is associated with a first SSB, and the target signal is used for the verification of the target AI model and / or the prediction of target beam-related information. The first SSB is at least a portion of the SSBs that are not enabled in the SSB burst set.

[0083] S420, the first communication device receives the first information sent by the second communication device.

[0084] The first information includes at least one of the relevant information of the target signal, the relevant information of the first SSB, and the relevant information of the second SSB, wherein the second SSB is at least a portion of the enabled SSBs in the SSB burst set.

[0085] S430, associate the relevant information of the target signal with the relevant information of the first SSB.

[0086] It is understood that the implementation process of S410-S430 can be referred to the relevant descriptions in method embodiments 200-300. To avoid repetition, it will not be repeated here.

[0087] S440, the first communication device uses the relevant information of the target signal associated with the relevant information of the first SSB and / or the relevant information of the second SSB as input information of the first AI model to predict the relevant information of the target beam.

[0088] It is understandable that, in scenarios where target beam-related information prediction needs to be performed using SSBs in the SSB burst set, if the input information of the first AI model includes the relevant information of an disabled SSB (i.e., the first SSB) in the SSB burst set, since the relevant information of the disabled SSB (i.e., the first SSB) cannot be obtained, the relevant information of the target signal associated with the relevant information of the first SSB can be used as (or replaced, adjusted, etc.) as input information to ensure the reliability and stability of the predicted target beam-related information.

[0089] Based on this, in one implementation, before using the relevant information of the target signal associated with the relevant information of the first SSB and / or the relevant information of the second SSB as input information of the first AI model, if the relevant information of the target signal includes beam quality-related information corresponding to the target signal (or the power on each resource corresponding to the target signal is inconsistent with the power on each resource corresponding to the second SSB), then the first communication device can adjust the power on each resource corresponding to the target signal according to a first power value.

[0090] It is worth noting that the first power value mentioned in this application, as well as the subsequent second, third, and fourth power values, can all be implemented by higher-level configurations, protocol agreements, etc., such as through signaling "powerControlOffsetSS," or determined by the first or second communication device based on the difference between the power on each resource corresponding to the target signal and the power on each resource corresponding to the second SSB. Furthermore, the first power value and the subsequent second, third, and fourth power values ​​can be the same or different, and this is not limited here.

[0091] Optionally, considering that in related technologies, when predicting target beam-related information for the first AI model based on the SSB burst set, a complete true label is required, but since the output of the first AI model is related to the number of beams transmitted by the first communication device (e.g., a base station), and the actual number of beams transmitted by the first communication device is less than the number of beams associated with the output of the first AI model, the first AI model cannot obtain a complete true label. Therefore, in this embodiment, when the first communication device predicts target beam-related information for the first AI model based on the relevant information of the target signal and / or the relevant information of the second SSB, if the first communication device inputs the relevant information of the target signal and / or the relevant information of the second SSB into the first AI model, and the predicted target beam-related information is associated with the relevant information of the first SSB, then the second information can be used as the label data corresponding to the relevant information of the first SSB associated with the target beam-related information to obtain a complete true label. The second information is related to the target signal; for example, the second information can be the identification information, name information, beam quality-related information, beam gain-related information, etc., of the target signal, and is not limited here.

[0092] In one implementation, before the first communication device associates the second information as tag data corresponding to the relevant information of the first SSB associated with the target beam-related information, if the second information includes beam quality-related information of the target signal (or the power on each resource corresponding to the target signal is inconsistent with the power on each resource corresponding to the second SSB), the power on each resource corresponding to the target signal can be adjusted according to the second power value.

[0093] In this scenario, assuming the input information of the first AI model is the RSRP of the beams corresponding to SSBs identified as 1, 3, 5, 7, and 9 in the SSB burst set, and the beam-related information is the RSRP of the beams corresponding to SSBs identified as 1-32, but SSBs identified as 3 and 5 in the SSB burst set are not enabled (i.e., their corresponding RSRPs cannot be obtained), and the target signal includes two CSI-RSs identified as 3 and 5, then the RSRP of the beams identified as 3 and 5 in the input information needs to use the RSRP of the CSI-RSs identified as 3 and 5.

[0094] Based on this, since the RSRP of the beams corresponding to SSBs identified as 1-32 in the target beam information of the first AI model is obtained based on the input information of the first AI model, it does not need to be adjusted. However, since the tag data associated with the target beam information is also assumed to be the actual measurement value of SSBs identified as 1-32, but since the beams identified as SSBs 3 and 5 do not exist, it is necessary to use the two CSI-RS identified as 3 and 5 as the tag data of SSBs identified as 3 and 5.

[0095] It is worth noting that in this embodiment, considering that the AI ​​model can be configured on the first communication device (i.e., the first AI model) or directly configured on the second communication device (i.e., the second AI model), in this embodiment, besides the second communication device sending the first information to the first device for AI model verification and target beam-related information prediction, the second device can also associate the target signal-related information with the first SSB-related information, and / or, the second device verifies the AI ​​model based on the target signal-related information and / or the second SSB-related information, and / or, the second communication device uses the target signal-related information and / or the second SSB-related information associated with the first SSB-related information as input information for the second AI model to predict the target beam-related information. Of course, the process of the second communication device verifying the second AI model and / or predicting the target beam-related information is similar to the aforementioned process of verifying the first AI model and / or predicting the target beam-related information, and is not limited here.

[0096] For example, if the relevant information of the target signal includes beam quality-related information corresponding to the target signal, the second communication device adjusts the power on each resource corresponding to the target signal according to a third power value.

[0097] For example, when the predicted target beam-related information is associated with the relevant information of the first SSB, the third information is used as the tag data corresponding to the relevant information of the first SSB associated with the target beam-related information, and the third information is related to the target signal.

[0098] In one implementation, before the first communication device uses the third information as the tag data corresponding to the relevant information of the first SSB associated with the target beam-related information, it may adjust the power on each resource corresponding to the target signal according to the fourth power value, provided that the relevant information of the first SSB includes beam quality-related information.

[0099] In this embodiment, by transmitting the target signal associated with the first SSB, complete information, such as beam quality-related information, can be obtained by combining the enabled SSBs in the SSB burst set with a small amount of additional reference signal.
