[0040] In order to make the ordinary person in the art better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings.
[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0042] In a current beam management method, channel state information, CSI, report configuration information received by a terminal device indicates a layer 1 reference signal receiving power, L1-RSRP; the terminal device selects a to-be-reported beam from multiple beams according to a measured L1-RSRP value and performs reporting processing.
[0043] In the above scheme, it is difficult to ensure the signal quality of the selected beam in combination with L1-RSRP value evaluation and beam selection, and the beam management efficiency is poor.
[0044] Figure 1 A flowchart of a beam management method according to an embodiment of the present disclosure. It should be noted that the beam management method according to the present embodiment can be applied to a beam management apparatus, which can be configured in an electronic device or a chip, so that the electronic device or the chip can perform a beam management function.
[0045] The electronic device can be any device with computing capability, such as a personal computer (PC), a mobile terminal, a terminal device, a server, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, etc. The mobile terminal can have various operating systems, touch screens, and / or display screens.
[0046] In addition, the beam management apparatus can also be software in the electronic device, etc. The software can be, for example, beam management software, etc. In the following embodiments, the execution subject is taken as an example of a terminal device.
[0047] As shown in FIG. 1, the method comprises the following steps: Figure 1
[0048] In step 101, channel state information, CSI, report configuration information of a network device is received; the CSI report configuration information indicates a to-be-measured parameter and a reference signal resource for beam measurement; the to-be-measured parameter includes a post-demodulation signal-to-noise ratio.
[0049] In the present embodiment, the CSI report configuration information can include a resource set identifier and a beam management report mode type. The resource set identifier indicates the reference signal resource for beam measurement. The beam management report mode type indicates the to-be-measured parameter.
[0050] The post-demodulation signal-to-noise ratio refers to the ratio between the signal power and the noise power after the reference signal is demodulated.
[0051] In the embodiments of the present disclosure, the terminal device receiving the CSI report configuration information and the network device can be devices in a wireless communication system. The wireless communication system can be, for example, a wireless cellular system, a satellite communication system, a microwave communication system, etc. The microwave communication system can be, for example, a millimeter wave communication system, etc.
[0052] At step 102, a demodulated signal-to-noise ratio of the to-be-measured beam is obtained by performing a demodulated signal-to-noise ratio measurement process on the to-be-measured beam in combination with the reference signal resource.
[0053] In the embodiments of the present disclosure, the reference signal resource can include at least one of the following: a channel state information reference signal (CSI-RS), a synchronization signal block (SSB). In addition, the reference signal resource can also be any reference signal resource that can be used for beam measurement, which is not specifically limited here and can be set according to actual needs.
[0054] In an example, the reference signal resource is a CSI reference signal. The terminal device performing step 102 can, for example, receive a CSI reference signal sent by the network device through the to-be-measured beam; send the received CSI reference signal to a demodulator for demodulation to obtain a demodulated signal; perform signal power measurement and noise power measurement on the demodulated signal to obtain the signal power and the noise power of the demodulated signal; and determine the value of the demodulated signal-to-noise ratio in combination with the signal power, the noise power, and a preset signal-to-noise ratio calculation formula.
[0055] The preset signal-to-noise ratio calculation formula can be shown in the following formula (1).
[0056]
[0057] In the formula, SNR represents the demodulated signal-to-noise ratio; P signal represents the signal power of the demodulated signal; and P noise represents the noise power of the demodulated signal.
[0058] The greater the value of the demodulated signal-to-noise ratio, the better the quality of the CSI reference signal and the smaller the noise interference.
[0059] In another example, the reference signal resource is a synchronization signal block. The process of step 102 performed by the terminal device may, for example, include receiving a synchronization signal block transmitted by the network device through the to-be-measured beam; sending the received synchronization signal block to a demodulator for demodulation processing to obtain a demodulated signal; performing signal power measurement processing and noise power measurement processing on the demodulated signal to obtain the signal power and the noise power of the demodulated signal; and determining the value of the demodulated signal-to-noise ratio in combination with the signal power, the noise power, and a preset signal-to-noise ratio calculation formula.
[0060] In this way, the terminal device can select a suitable reference signal resource for beam measurement processing according to actual needs, improving the flexibility of beam measurement and further improving the efficiency of beam measurement.
[0061] Step 103: Selecting, in combination with the value of the demodulated signal-to-noise ratio, to-be-reported beams from the to-be-measured beams.
[0062] In an example in the embodiments of the present disclosure, the process of step 103 performed by the terminal device may, for example, include performing descending order sorting processing on each to-be-measured beam in combination with the value of the demodulated signal-to-noise ratio to obtain a sorting result; and determining a certain number of to-be-measured beams sorted in the front in the sorting result as to-be-reported beams.
[0063] In another example, the process of step 103 performed by the terminal device may, for example, include performing ascending order sorting processing on each to-be-measured beam in combination with the value of the demodulated signal-to-noise ratio to obtain a sorting result; and determining a certain number of to-be-measured beams sorted in the back in the sorting result as to-be-reported beams.
[0064] In another example, the process of step 103 performed by the terminal device may, for example, include sequentially determining, for each to-be-measured beam, the to-be-measured beam as a to-be-reported beam in a case where the value of the demodulated signal-to-noise ratio of the to-be-measured beam is greater than or equal to a preset numerical threshold; and stopping the judging and determining process in a case where the number of to-be-reported beams determined is greater than or equal to a certain number.
[0065] Step 104: Performing beam reporting processing in combination with the to-be-reported beams.
[0066] In the embodiments of the present disclosure, the process of step 104 performed by the terminal device may, for example, include adding the beam identifier of the to-be-reported beam to a specified beam subset in the plurality of beam subsets; reporting the plurality of beam subsets to the network device and reporting a CSI report; and carrying the identifier of the specified beam subset in the CSI report to instruct the network device to obtain the to-be-reported beam from the specified beam subset and perform beam scheduling processing in combination with the to-be-reported beam.
[0067] The multiple beam subsets and the CSI report can be carried in different messages for reporting. The existing protocol stipulates multiple reporting methods of the beam subsets. Before reporting the multiple beam subsets, the terminal device can select one beam subset from the multiple beam subsets as a designated beam subset, and add the beam identifier of the selected beam to be reported to the designated beam subset.
[0068] The CSI report can further include a to-be-measured parameter value of the beam to be reported and a reference signal used for measuring the to-be-measured parameter value. The reporting of the reference signal and the to-be-measured parameter value enables the network device to comprehensively consider the to-be-measured parameter value of the beam to be reported reported by each terminal device when performing beam scheduling on multiple terminal devices, thereby improving the beam management efficiency and the beam scheduling efficiency for the multiple terminal devices.
[0069] The reporting of the beam to be reported by multiplexing the existing beam subsets can reduce the data amount in the CSI report, thereby improving the reporting efficiency of the CSI report and further improving the beam management efficiency.
[0070] In the beam management method of the embodiment of the present disclosure, the channel state information (CSI) report configuration information of the network device is received. The CSI report configuration information indicates a to-be-measured parameter and a reference signal resource used for beam measurement. The to-be-measured parameter includes a demodulation signal-to-noise ratio. The demodulation signal-to-noise ratio of the to-be-measured beam is measured by combining the reference signal resource, and the demodulation signal-to-noise ratio value of the to-be-measured beam is obtained. The beam to be reported is selected from the to-be-measured beam by combining the demodulation signal-to-noise ratio value. The beam reporting processing is performed by combining the beam to be reported. The beam selection processing by combining the demodulation signal-to-noise ratio can consider the actual demodulation capability of the beam on the channel, thereby ensuring the signal quality of the selected beam and improving the beam management efficiency.
[0071] Figure 2 The flowchart of the beam management method of another embodiment of the present disclosure is shown. It should be noted that the beam management method of the embodiment can be applied to a beam management apparatus, which can be configured in an electronic device or a chip, so that the electronic device or the chip can perform the beam management function.
[0072] The electronic device can be any device with computing capability, such as a personal computer (PC), a mobile terminal, a terminal device, a server, etc. The mobile terminal can be a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, etc. The mobile terminal can have various operating systems, touch screens, and / or display screens.
[0073] In addition, the beam management apparatus can also be software in the electronic device. The software can be, for example, beam management software.
[0074] As shown in Figure 2 The method comprises the following steps:
[0075] In step 201, channel state information (CSI) report configuration information of a network device is received. The CSI report configuration information indicates to-be-measured parameters and reference signal resources for beam measurement. The to-be-measured parameters include a demodulation signal-to-noise ratio (SNR) and a noise-related parameter.
[0076] In the embodiments of the present disclosure, the noise-related parameter can include at least one of white noise, noise covariance, and interference plus noise. The white noise refers to random noise with uniform spectral components in the audible range. The noise covariance is a statistical index for measuring the relationship between the intensity changes of noise signals at different time points or different frequency points.
[0077] In step 202, a demodulation SNR of a to-be-measured beam is measured by combining the reference signal resources, and a demodulation SNR value of the to-be-measured beam is obtained.
[0078] In the embodiments of the present disclosure, the process performed by the terminal device in step 102 can be, for example, receiving reference signal resources sent by the network device through the to-be-measured beam; sending the received reference signal resources to a demodulator for demodulation processing to obtain a demodulated signal; performing signal power measurement processing and noise power measurement processing on the demodulated signal to obtain signal power and noise power of the demodulated signal; and combining the signal power, the noise power, and a preset SNR calculation formula to determine the value of the demodulation SNR.
[0079] In step 203, a noise-related parameter of a to-be-measured beam is measured by combining the reference signal resources, and a noise-related parameter value of the to-be-measured beam is obtained.
[0080] In the embodiments of the present disclosure, the process performed by the terminal device in step 203 can be, for example, receiving reference signal resources sent by the network device through the to-be-measured beam; and performing noise-related parameter measurement processing on the received reference signal resources to obtain the noise-related parameter value of the to-be-measured beam.
[0081] In the embodiments of the present disclosure, there is a correlation between the noise-related parameters and the demodulated signal-to-noise ratio. That is, the white noise and the noise covariance in the noise-related parameters affect the demodulation capability, and the demodulated signal-to-noise ratio represents the demodulation capability. Therefore, in order to select an accurate to-be-reported beam, the correlation between the noise-related parameters and the demodulated signal-to-noise ratio can be decoupled. Correspondingly, after step 203, the terminal device can further perform the following process: determining a target demodulated signal-to-noise ratio value in combination with the noise-related parameter value, the demodulated signal-to-noise ratio value, and the complementary filtering algorithm; and updating the demodulated signal-to-noise ratio value according to the target demodulated signal-to-noise ratio value.
[0082] The formula of the complementary filtering algorithm can be as shown in the following formula (2).
[0083] second_signaling=k1*second_signaling+k2*K*first_signaling(2)
[0084] In the formula, second_signaling on the left side of the equation represents the target demodulated signal-to-noise ratio value; second_signaling on the right side of the equation represents the demodulated signal-to-noise ratio value; and first_signaling can represent the noise-related parameter value. The noise-related parameter value on the right side of the equation, for example, is a white noise value and / or a noise covariance value. k1, k2, and K represent coefficients.
[0085] Step 204: selecting a to-be-reported beam from the to-be-measured beams in combination with the demodulated signal-to-noise ratio value and the noise-related parameter value.
[0086] In the embodiments of the present disclosure, the process performed by the terminal device in step 204 can be, for example, determining a demodulated signal-to-noise ratio weight and a noise-related parameter weight; performing weighting processing on the demodulated signal-to-noise ratio value and the noise-related parameter value in combination with the demodulated signal-to-noise ratio weight and the noise-related parameter weight to obtain a measurement score of each to-be-measured beam; performing sorting processing on each to-be-measured beam according to the measurement score to obtain a sorting result; and selecting a to-be-reported beam from the to-be-measured beams according to the sorting result.
[0087] In the embodiments of the present disclosure, the process of determining the demodulated signal-to-noise ratio weight and the noise-related parameter weight by the terminal device can be, for example, obtaining a performance-related parameter of a terminal device receiving the CSI report configuration information; determining scene information of the terminal device in combination with the performance-related parameter; and obtaining a demodulated signal-to-noise ratio weight and a noise-related parameter weight corresponding to the scene information.
[0088] Different scenario information can correspond to different demodulated signal-to-noise ratio (SNR) weights and / or different noise-related parameter weights. The measured parameters are emphasized differently in different scenario information. For example, in scenario 1, the white noise weight is -1, the noise covariance weight is -1.5, and the interference plus noise weight is -0.8; the demodulated SNR weight is 2. In scenario 2, the white noise weight is -0.3, the noise covariance weight is -0.4, and the interference plus noise weight is -0.7; the demodulated SNR weight is 2.2. In scenario 3, the white noise weight is -1.9, the noise covariance weight is -2.1, and the interference plus noise weight is -2.2; the demodulated SNR weight is 0.9.
[0089] Among them, the setting of different weights for the parameters to be measured in different scenario information allows the terminal device to select appropriate weights based on the specific scenario, and to emphasize different parameters to be measured in different scenarios, thereby improving the flexibility of weight setting and further improving the flexibility of beam selection.
[0090] Step 205: Perform beam reporting processing in conjunction with the beam to be reported.
[0091] In this embodiment of the disclosure, the process of the terminal device performing step 205 may, for example, be adding the beam identifier of the beam to be reported to the CSI report and reporting the CSI report to the network device.
[0092] The CSI report may also include the measured parameters of the beam to be reported, as well as the reference signal used to measure these parameters. These measured parameters may include, for example, the demodulated signal-to-noise ratio, white noise, noise covariance, and interference plus noise.
[0093] It should be noted that for detailed explanations of steps 201 to 202, and step 205, please refer to [link / reference needed]. Figure 1 Steps 101 to 102 and step 104 in the illustrated embodiment will not be described in detail here.
[0094] In the beam management method of the embodiment of the present disclosure, channel state information (CSI) report configuration information of a network device is received. The CSI report configuration information indicates to-be-measured parameters and reference signal resources used for beam measurement. The to-be-measured parameters include a post-demodulation signal-to-noise ratio and a noise-related parameter. The post-demodulation signal-to-noise ratio of a to-be-measured beam is measured by combining the reference signal resources, to obtain a post-demodulation signal-to-noise ratio value of the to-be-measured beam. The noise-related parameter of the to-be-measured beam is measured by combining the reference signal resources, to obtain a noise-related parameter value of the to-be-measured beam.
