[0039] Next, with reference to the accompanying drawings, the beam quality measurement method and device provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0040] As Figure 2 shown, the embodiments of the present application provide a beam quality measurement method 200. This method can be executed by a terminal. In other words, this method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0041] S202: The terminal receives the reference signal forwarded by the wireless auxiliary device; wherein, the reference signal is sent by the network device and forwarded by the wireless auxiliary device through multiple beams at different times.

[0042] S204: Jointly process the reference signals with the same beam of the network device and the same beam of the wireless auxiliary device to obtain a processing result; the joint processing includes layer one filtering and / or layer three filtering.

[0043] The reference signals mentioned in the embodiments of the present application can be used for a terminal to measure the beam of a wireless auxiliary device. These reference signals can be downlink reference signals such as synchronization signals and physical broadcast block (SSB), and channel state information-reference signal (CSI-RS).

[0044] The wireless auxiliary devices mentioned in the embodiments of the present application can be large intelligent surfaces (LIS), relay devices, backscatters, satellites, etc.

[0045] As Figure 3 shown, Figure 3 is a schematic diagram of an application scenario of the beam quality measurement method according to an embodiment of the present application. In this embodiment, the network-side device can send reference signals to the wireless auxiliary device through one or more beams. The wireless auxiliary device can receive the reference signals and forward the reference signals through multiple different beams at different times.

[0046] In Figure 3 the shown embodiment, specifically, the network-side device sends reference signals to the wireless auxiliary device, and the wireless auxiliary device forwards the reference signals through three different beams at different times. Since the relative position and channel conditions between the network-side device and the wireless auxiliary device remain quasi-static, the reference signals have consistent signal identifiers and / or ports at the network-side device (such as Figure 3 port K in), that is, the transmission parameters of the network-side device remain unchanged. Since the wireless auxiliary device does not change the sequence information / baseband information of the reference signals, the terminal usually cannot distinguish the reference signals with the same identifier but different beams. It can be understood that if the terminal measures the reference signals with the same identifier but different beams, the obtained measurement results will not accurately reflect the channel conditions of multiple beams of the wireless auxiliary device.

[0047] In this embodiment, the terminal can jointly process the reference signals with the same beam of the network device and the same beam of the wireless auxiliary device to obtain a processing result.

[0048] As Figure 4 shown,Figure 4 Shown is a schematic diagram of a wireless auxiliary device forwarding periodic reference signals with three forwarding beams (or simply referred to as beams). In this example, the terminal can perform joint processing of layer-1 filtering on the reference signals of beam 1; the terminal can perform joint processing of layer-1 filtering on the reference signals of beam 2; the terminal can perform joint processing of layer-1 filtering on the reference signals of beam 3.

[0049] In this embodiment, the terminal can perform joint processing on reference signals with the same identifier or the same port number, and these reference signals with the same identifier or port number can be sent by the network device to the wireless auxiliary device through the same (or the same) beam.

[0050] At the same time, in order to enable the terminal to perform joint processing on reference signals with the same beam of the wireless auxiliary device, in one example, the terminal can determine the reference signals with the same beam based on the beam execution period of the wireless auxiliary device. For example, if the beam execution period of the wireless auxiliary device is T, then the reference signals received by the terminal at time t1 and at time (t1 + T) are usually from the same beam of the wireless auxiliary device. In another example, the network-side device can configure the wireless auxiliary device so that multiple reference signals that appear within a time window W are forwarded by the same beam of the wireless auxiliary device, and this time window is used for the terminal to measure the reference signals. The time window W is less than or equal to the beam execution time and greater than or equal to the period P of the reference signals to be measured.

[0051] The joint processing mentioned in this embodiment can include layer-1 filtering, can also include layer-3 filtering, and can also include layer-1 filtering + layer-3 filtering. For example, the terminal inputs the result of layer-1 filtering into the corresponding layer-3 filter for layer-3 filtering.

[0052] Optionally, the processing result mentioned in this implementation example includes the beam information of multiple beams of the wireless auxiliary device, and this embodiment can also include the following steps: The terminal reports the beam information to the network-side device, where the beam information includes the identifiers of multiple strongest beams. In this way, subsequently, the network-side device can also perform beam indication on the terminal based on the identifiers of the strongest beams, so that the terminal can communicate with the wireless auxiliary device through the strongest beams, improving the communication quality.

[0053] For the beam quality measurement method provided by the embodiments of this application, the terminal receives the reference signals forwarded by the wireless auxiliary device, and performs joint processing on the reference signals with the same beam of the network device and the same beam of the wireless auxiliary device to obtain a processing result, avoiding the problem of low accuracy of beam quality measurement caused by the terminal performing joint processing on reference signals with different beams of the wireless auxiliary device or performing joint processing on reference signals with different beams of the network-side device, and can improve the accuracy of beam quality measurement.

[0054] Optionally, before S202 of Embodiment 200, the terminal may further receive configuration information of the reference signal, which may be sent by a network-side device, and the configuration information may include at least one of the following:

[0055] 1) The identifier or port number of the reference signal. For example, the network-side device configures the identifier or port number of the reference signal that the terminal needs to measure.

[0056] 2) The time-frequency resource parameters of the reference signal. For example, it includes the time-domain resource of the reference signal to be measured, the frequency-domain resource of the reference signal to be measured, the transmission period of the reference signal to be measured, etc.

[0057] 3) The time configuration parameters for performing the reference signal measurement behavior. The time configuration parameters include: the start time and end time of the time window of the measurement behavior, or the time length of the time window of the measurement behavior, the measurement period, and the minimum time interval between two adjacent reference signal measurement behaviors.

[0058] The terminal may obtain the time-domain position of the time window for which the reference signal needs to be measured according to the time configuration parameters.

[0059] 4) The joint processing criterion of the reference signal; wherein, the joint processing criterion includes: the measurement result processing method based on layer-one filtering, and the measurement result processing method based on layer-three filtering. The terminal may perform the operation of jointly processing the reference signal in S204 based on the joint processing criterion.

[0060] In one example, the configuration information received by the terminal may be used to configure all of the above four. In other examples, if the configuration information does not configure some or all of the above four, the terminal may obtain the unconfigured part of the above four through other means. For example, if the configuration information does not configure the joint processing criterion in 4) above, the terminal may obtain the joint processing criterion of the reference signal based on protocol agreements, etc.

[0061] As shown above, the joint processing mentioned in S204 of Embodiment 200 includes layer-one filtering and / or layer-three filtering. The following will separately describe the joint processing process of layer-one filtering and the joint processing process of layer-three filtering in Solution 1 and Solution 2.

[0062] Solution 1

[0063] The joint processing mentioned in S204 of Embodiment 200 includes layer-one filtering, and the configuration information mentioned in the above embodiment may further include at least one of the following:

[0064] 1) The number of beams of the wireless assistance device. For example, in Figure 3In the example shown, the number of beams of the wireless assistance device is 3.

[0065] 2) The total time length and execution period of the beam execution of the wireless assistance device, where the execution period is less than the time length of the time window of the measurement behavior.

[0066] The total time length of the beam execution can refer to Figure 3 the total time length occupied on the time axis in Figure 3 , Figure 3 which schematically shows two execution periods.

[0067] In this example, it is mentioned that the execution period is less than the time length of the time window of the measurement behavior. For example, the time length of the time window of the measurement behavior is equal to 2, 3, 4 or more execution periods. Optionally, through protocol pre - definition, when the time window of the measurement behavior contains the execution periods of multiple wireless assistance devices, the layer - one filter is configured by default.

[0068] 3) The number of beams to be measured by the wireless assistance device and the beam execution time of the beams to be measured. For example, in Figure 4 the example shown, the number of beams to be measured is 3, specifically beam 1, beam 2, and beam 3. This configuration information is also used to configure the beam execution time of the above three beams. In Figure 4 the example shown, the length of the beam execution time of each beam is the length occupied by one grid on the time axis.

[0069] 4) The beam screening rule of the wireless assistance device, where the beam screening rule includes: selecting the strongest Y beams from the multiple measured beams for layer - one filtering or selecting the Y best measurement results after layer - one filtering and reporting them to the upper layer, where Y is a positive integer.

[0070] The strongest Y beams or the Y best measurement results mentioned here can be measured based on the following indicators of the reference signal corresponding to the beam: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indication (RSSI), etc.

[0071] In Solution 1, the terminal can obtain reference signals with the same beam based on the beam execution period of the wireless assistance device. For example, if the beam execution period of the wireless assistance device is T, the reference signals received by the terminal at time t1 and at time (t1 + T) are usually from the same beam of the wireless assistance device. Specifically, for example, the time interval between two adjacent reference signals used for layer 1 filtering in this Solution 1 is a fixed value, equal to the beam execution period T of the wireless assistance device. For example, if the length of the time window for reference signal measurement is nT, there are n reference signals within the time window corresponding to the same beam of the wireless assistance device. That is, several measurement results that meet the requirements of layer 1 filtering can be selected from the above n reference signals and input into the layer 1 filter.

[0072] In Solution 1, the terminal jointly processes the reference signals with the same beam of the network device and the same beam of the wireless assistance device, and the obtained processing result may include: the terminal inputs the measurement results of the reference signals with the same beam of the network device and the same beam of the wireless assistance device into the layer 1 filter according to the configuration information to obtain the processing result.

[0073] In Solution 1, the terminal can also determine the number N of parallel layer 1 filters corresponding to the reference signals according to the number of beams of the wireless assistance device or the number of beams to be measured by the wireless assistance device. For example, the number of beams of the wireless assistance device is equal to the number N of parallel layer 1 filters corresponding to the reference signals, or the number of beams to be measured by the wireless assistance device is equal to the number N of parallel layer 1 filters corresponding to the reference signals. Among them, the number of beams of the wireless assistance device or the number of beams to be measured by the wireless assistance device can be configured by the above configuration information.

[0074] In Solution 1, the terminal can also select Y results from the N parallel layer 1 filtering results according to the beam screening rule and report them to the upper layer. The beam screening rule can be configured by the above configuration information, and these Y measurement results can be the best one or more selected from all the measurement results of the terminal.

[0075] In Solution 1, the physical layer of the terminal can also measure the correlation of the reference signals of different beams of the wireless assistance device and perform at least one of the following: report the correlation measurement result to the upper layer; according to the correlation measurement result, select whether to merge and report the measurement results of the reference signals of different beams of the wireless assistance device to the upper layer.

[0076] Solution 2

[0077] The joint processing mentioned in S204 of Embodiment 200 includes layer 3 filtering. The configuration information mentioned in the previous embodiments of Solution 1 may further include at least one of the following:

[0078] 1) The number of beams of the wireless assisting device. For example, in the Figure 5 example shown, the number of beams of the wireless assisting device is 3.

[0079] 2) The total time length and execution period of the beam execution of the wireless assisting device, where the execution period is greater than the time length of the time window of the measurement behavior.

[0080] The total time length of the beam execution can refer to the Figure 5 total time length occupied on the time axis in Figure 5 the example shown. In the

[0081] example shown, the total time length of the beam execution is equal to the length of the execution period. Figure 5 3) The number of beams to be measured by the wireless assisting device and the beam execution time of the beams to be measured. For example, in the

[0082] example shown, the number of beams to be measured is 3, specifically beam 1, beam 2, and beam 3. This configuration information is also used to configure the beam execution time of the above three beams. Figure 5 In this example, it is mentioned that the execution period of each beam is greater than the time length of the time window of the measurement behavior. For example, the time length of the time window of the measurement behavior is less than or equal to

[0083] the total time length shown in

[0084] Optionally, the terminal can also determine the number N of parallel layer 3 filters corresponding to the reference signal according to the number of beams of the wireless assisting device or the number of beams to be measured by the wireless assisting device. For example, the number of beams of the wireless assisting device is equal to the number N of parallel layer 3 filters corresponding to the reference signal, or the number of beams to be measured by the wireless assisting device is equal to the number N of parallel layer 3 filters corresponding to the reference signal. Among them, the number of beams of the wireless assisting device or the number of beams to be measured by the wireless assisting device can be configured by the above configuration information.

[0085] 1) The reference signals that appear within a time window are forwarded by the same beam of the wireless assisting device. This time window can be the time window configured by the network side device for the terminal to perform reference signal measurement, as detailed in the measurement behavior time window introduced in the previous configuration information section.

[0086] In this example, within a time window, the network device sends the reference signal to be measured multiple times, and the wireless assisting device forwards the reference signal to be measured using the same beam within a time window.

[0087] 2) The beams of the wireless assisting device corresponding to time windows with different configurations are different.

[0088] The time windows with different configurations mentioned in this example can be time windows configured by the network side device for the terminal and respectively used to measure different beams of the wireless assisting device.

[0089] In Solution 2, the joint processing of the reference signals with the same beam of the network device and the same beam of the wireless assisting device to obtain the processing result includes: according to the configuration information, inputting the output result of the layer-1 filter into the corresponding layer-3 filter to obtain the processing result.

[0090] Optionally, in an example, there is a one-to-one correspondence between the layer-1 filter and the layer-3 filter, and one layer-1 filter corresponds to one forwarding beam of the wireless assisting device.

[0091] Alternatively, optionally, the layer-1 filter is a filter without aftereffect, that is, the filtering result of the current time window is not affected by the measurement result of the previous time window. There is a one-to-many correspondence between the layer-1 filter and the layer-3 filter. The output result of the layer-1 filter is input into the corresponding layer-3 filter according to the correspondence of the wireless assisting device.

[0092] To illustrate in detail the beam quality measurement method provided in the embodiments of the present application, the following will be described in conjunction with two specific embodiments.

[0093] Embodiment 1

[0094] This Embodiment 1 corresponds to Solution 1 in the foregoing text.

[0095] In this embodiment, if the beams to be measured by the terminal are multiple beams forwarded by the wireless assisting device, and within the time period of the forwarding beam of the wireless assisting device, there are multiple reference signals that can be used for measurement (for example, RSs belonging to the same RS configuration (such as periodic RS), but the RSs at different times correspond to different beams of the wireless assisting device), then the network side device (base station) configures the parameters of the layer-1 filter (L1 filter) for the terminal for the filtering rule of the terminal, so that the terminal filters the measurement results of the same beam. The filtering rule can include the time interval of the same beam, the screening rule of multiple beams, the collaborative reporting of measurement auxiliary information, etc.

[0096] Prior to this embodiment, the base station can obtain basic information of the wireless auxiliary device through the interface between the base station and the wireless auxiliary device, such as the forwarding beam of the wireless auxiliary device, the execution time length and execution cycle of each forwarding beam, and the sending beam from the base station to the wireless auxiliary device. In this embodiment, it is assumed that the wireless auxiliary device has ensured time synchronization / frame synchronization with the base station.

[0097] This embodiment may include the following steps:

[0098] Step 1: The base station configures the base station beam set to be measured for the terminal and indicates additional measurement criteria. For details, please refer to the introduction of the configuration information part in the above solution 1. Step 1 can be implemented by the following method 1 or method 2.

[0099] Method 1: Explicit indication method, the base station explicitly indicates the measurement and filtering behavior of the terminal.

[0100] For example, the base station specifies that the reference signals corresponding to one or several base station beams need to comply with additional measurement criteria.

[0101] The additional measurement criteria may include a measurement requirement for the input information of the layer one filter, requiring that the time interval between two adjacent reference signals used for filtering is a fixed value, which is equal to the beam execution period T of the wireless auxiliary device. The base station considers the cycle period T of the beam execution of the wireless auxiliary device when configuring the measurement time window of the reference signal. If the input information required by the layer one filter is at least n measurement results, the length of the measurement time window should be no less than nT.

[0102] In this example, the terminal determines the required amount of input data for layer one filtering according to the configured time window and the time interval between two adjacent reference signals, for example, by dividing the length of the time window by the time interval between two adjacent reference signals.

[0103] Method 2: Implicit method: The UE determines the measurement and filtering behavior of the UE based on the configuration information 1 (the forwarding beam of the wireless auxiliary device, and the execution time length and period of each forwarding beam) and configuration information 2 (the configuration of the reference signal to be measured, including at least the time domain resources where the reference signal is located) sent by the base station.

[0104] For example, the UE determines the measurement and filtering behavior of the UE according to configuration information 1 and configuration information 2, and the first rule defined by the protocol; wherein the first rule is: only the reference signal at the same forwarding beam moment of the wireless auxiliary device can perform layer one filtering, or, the forwarding beams of the wireless auxiliary device corresponding to multiple moments of layer one filtering need to be the same.

[0105] Optionally, the interval and number of moments for layer-1 filtering can be configured by the base station, defined by the protocol, or implemented by the UE.

[0106] The additional measurement criterion may include the parallel number of layer-1 filtering for reference signals of the same port or ID. It can be understood that in a time window, the reference signals to be measured are sent multiple times and forwarded by the wireless assisting device with multiple different forwarding beams. The parallel number of layer-1 filtering indicates the number of different beams that need to be measured.

[0107] The additional measurement criterion may include the screening rules for multiple beams. One screening rule is that the terminal selects the strongest Y beams from the multiple measurable beams for layer-1 filtering or selects the Y best results after layer-1 filtering and reports them to the upper layer. Another screening rule is that the base station configures the beams to be measured for the terminal, such as indicating the position where the beam to be measured first appears in the measurement time window (the time offset from the start boundary of the window).

[0108] Optionally, the number of beams measured by the terminal is determined according to the required number of layer-1 filters. For example, the number of beams to be measured is equal to the number of layer-1 filters.

[0109] Step 2: The terminal measures the reference signals according to the above base station configuration and reports the layer-1 filtering results to the upper layer.

[0110] Optionally, the terminal can also receive the reference signals of multiple beams from the wireless assisting device and measure the correlation between the reference signals of different beams; the terminal selects whether to merge and report the measurement results of the reference signals of two or more beams to the upper layer according to the correlation measurement results.

[0111] Optionally, the terminal can report the signal correlation measurement results.

[0112] Step 3: The terminal selects several strongest beams after layer-3 filtering and reports them to the base station.

[0113] If the reported beams include the forwarding beams of the wireless assisting device, the terminal separately indicates the beam ID in the reported information, corresponding to the numbers of the multiple parallel layer-1 filters in Step 1.

[0114] Optionally, through protocol stipulation or base station configuration, the terminal selects N1 strongest beams from the measurement results of the normal configuration and N2 strongest beams from the measurement results of the additional configuration, and reports them to the base station respectively.

[0115] Optionally, the terminal reports the signal correlation measurement results to the base station for assisting the base station in scheduling.

[0116] Embodiment 2

[0117] The second embodiment corresponds to the second solution in the foregoing text.

[0118] In this embodiment, the base station configures a wireless auxiliary device to ensure that all the reference signals to be measured that appear within a time window are forwarded by the same beam of the wireless auxiliary device; different configured time windows correspond to different beams of the wireless auxiliary device. The base station implements the beam measurement function of the wireless auxiliary device by configuring the parameters of the terminal layer 3 filter.

[0119] This embodiment may include the following steps:

[0120] Step 1: The base station configures the parameters of the layer 3 filter for the terminal.

[0121] The additional layer 3 filtering configuration includes the number of parallel layer 3 filters for the same layer 1 filtering input information, and the number corresponds to the number of beams to be measured of the wireless auxiliary device.

[0122] The base station configures the beam execution time for the wireless auxiliary device to ensure that the wireless auxiliary device uses the corresponding forwarding beam within the symbol time of the time slot where the reference signal to be measured is located or in the adjacent symbols before and after. This configuration can be semi-statically configured or dynamically configured.

[0123] Step 2: The terminal sequentially executes N layer 3 filters according to the configured parameters.

[0124] For example, for the measurement result of the i-th measurement period, it is input into the mod(i, N)-th layer 3 filter, where i is the number of the measurement period and i is a positive integer.

[0125] Specifically, for example, there is a one-to-one correspondence between the layer 1 filter and the layer 3 filter, both being 2. The measurement result of the first measurement period is input into layer 3 filter 1, the measurement result of the second measurement period is input into layer 3 filter 2, the measurement result of the third measurement period is input into layer 3 filter 1, the measurement result of the fourth measurement period is input into layer 3 filter 2, the measurement result of the fifth measurement period is input into layer 3 filter 1, and so on.

[0126] Step 3: The terminal selects several strongest beams after layer 3 filtering and reports them to the base station.

[0127] This step can refer to step 3 of the first embodiment.
