Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a beamforming determination method, apparatus, device, and non-instantaneously readable storage medium. Background Technology

[0002] Wireless communication systems built on multiple RIS (Reconfigurable Intelligence Surface) architectures can, on the one hand, dynamically establish line-of-sight links on demand in blind spots or cell edges where line-of-sight communication is unreachable or signal quality is poor, by deploying RIS devices between base stations and end users, thereby improving network coverage quality and reducing coverage blind spots. On the other hand, distributed RIS nodes can be used to build distributed multipoint transmission, achieving higher diversity or multiplexing (and / or shaping) gain. However, since RIS are passive devices (unable to process forwarded signals), they directly forward signals in their operating frequency band (e.g., through transmission, reflection, etc.), meaning all signals arriving at the RIS will be forwarded. Therefore, regardless of the situation, for a multi-RIS, multi-UE (User Equipment) system, a signal forwarded by the RIS beam may be useful for UE1, but interference for UE2 (UE2 refers to other UEs besides UE1). In other words, the RIS beam may interfere with non-target UEs (such as UE2).

[0003] As mentioned above, in existing technologies, when multiple RIS beams serve multiple UE scenarios, there are issues such as the RIS beams interfering with non-target UEs. Summary of the Invention

[0210] The following section will first introduce the content related to the solutions provided in the embodiments of this application.

[0211] For a single RIS system, system performance can be improved by statically or semi-statically fixing the coverage or direction of the RIS to a specific region and establishing fixed virtual links. However:

[0212] For example Figure 2 The multi-UE wireless communication system based on multiple RIS (Radio Router Array) shown here needs to consider not only signal coverage but also interference between multiple RIS and multiple UEs. Currently, there are only coverage enhancement schemes for single-RIS, single-UE systems, and no effective and feasible interference coordination schemes for multi-RIS, multi-beam systems.

[0213] Furthermore, current coverage enhancement schemes for single RIS or single UE are not applicable to interference coordination and scheduling in multi-RIS, multi-beam scenarios. For multi-RIS, multi-beam systems, how to adjust the phase shift matrices of multiple RIS (i.e., adjust the RIS beams) to provide fair and consistent service to multiple UEs (or improve cell capacity) is a pressing issue. To address this, it is necessary to rationally coordinate the coverage direction and range of different RIS beams to reduce interference between different UEs and improve system performance.

[0214] Based on the above, embodiments of this application provide a beamforming determination method, apparatus, device, and non-transiently readable storage medium to solve the problem in the prior art where multiple RIS beams serving multiple UEs can cause interference to non-target UEs. The method, apparatus, device, and non-transiently readable storage medium are based on the same application concept. Since the principles by which the method, apparatus, device, and non-transiently readable storage medium solve the problem are similar, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0215] The beamforming determination method provided in this application embodiment is applied to a terminal, such as... Figure 3 As shown, it includes:

[0216] Step 31: Measure at least two beam measurement signals sent by at least two first network devices to obtain measurement information; the beam measurement signals are associated with beams in a first region; the measurement information includes: channel information corresponding to the beam measurement signals, or, at least one channel information corresponding to the beam measurement signals and at least one interference information corresponding to the beam measurement signals.

[0217] Wherein, the first network device can be a RIS device; and / or, the measurement information can include one or more of the following: RIS indication, RIS beam indication, RIS measurement signal indication, and corresponding measurement results (e.g., at least one of RSRP (Reference Signal Receiving Power), CSI (Channel State Information), PMI (Pre-coding matrix Indication), BLER (Block Error Rate), etc.); wherein, "RIS indication, RIS beam indication, and / or RIS measurement signal indication" can be information indicating related identity, such as identity identifier, specifically, for example: RIS indication is used to indicate the identity information of the RIS (device), and can be any signaling or information that has the meaning of indicating RIS, such as RIS index; RIS beam indication is used to indicate the identity information of the RIS beam; but is not limited thereto.

[0218] Step 31 may include: measuring at least two beam measurement signals sent by at least two first network devices respectively to obtain measurement information; wherein the beam measurement signal may be uniquely associated with one or more beams in a first region; the measurement information includes: channel information corresponding to each beam measurement signal, or, channel information corresponding to at least one beam measurement signal and interference information corresponding to at least one beam measurement signal; but is not limited thereto.

[0219] Step 32: Send the target measurement information from the measurement information to the second network device; the target measurement information includes at least a portion of the information in the measurement information.

[0220] The information may include, but is not limited to, measurement information for at least a portion of the beam measurement signals.

[0221] The beamforming determination method provided in this application embodiment measures at least two beam measurement signals sent by at least two first network devices to obtain measurement information; the beam measurement signals are associated with beams in a first region; the measurement information includes: channel information corresponding to the beam measurement signals, or at least one channel information corresponding to the beam measurement signals and at least one interference information corresponding to the beam measurement signals; the target measurement information in the measurement information is sent to a second network device; the target measurement information includes at least a portion of the information in the measurement information; it can support determining the serving beam of the terminal based on the measurement information measured by the terminal (for example, selecting the beam with better channel quality and less interference to other terminals corresponding to the terminal as the serving beam, or selecting the beam with the best channel quality corresponding to the terminal as the serving beam, and further processing the interference beam of the terminal, etc.), so as to reduce interference conflicts, improve system performance, and support solving the problem that in the prior art, multiple RIS beams serving multiple UE scenarios, the RIS beams may cause interference to non-target UEs.

[0222] In this embodiment of the application, the step of measuring at least two beam measurement signals sent by at least two first network devices to obtain measurement information includes: measuring at least two beam measurement signals sent by at least two first network devices within a first time period to obtain measurement information. This can achieve energy saving to a certain extent. The phrase "measuring at least two beam measurement signals sent by at least two first network devices to obtain measurement information" can include: measuring at least two beam measurement signals sent by each of the at least two first network devices to obtain measurement information, but is not limited to this. The first time period can be understood as measurement time T or measurement duration, etc., and is not limited here.

[0223] Furthermore, the beamforming determination method further includes: determining the reporting timing for sending the target measurement information to the second network device based on the reporting parameters indicated by the first configuration information, and / or determining the target measurement information; wherein, the first configuration information is predefined information (which may be a predefined rule) or information indicated by the second network device. This can support accurate reporting of target measurement information. The second network device can be implemented as a base station; and / or, the reporting timing is, for example, reporting at the nth symbol of the mth slot after the measurement time T ends; and / or, determining the target measurement information may include: determining the target measurement information based on reporting content determination rules, but is not limited to this.

[0224] The reporting parameters include at least one of the rules for determining the reporting timing and reporting content. This enables accurate determination and reporting of the target measurement information.

[0225] In this embodiment of the application, the reporting content determination rule includes at least one of the following: (1) taking the measurement information corresponding to at least one beam measurement signal under at least one service device as the reporting content; the service device refers to the first network device corresponding to the service beam and providing services to the terminal; (2) taking the measurement information corresponding to all received beam measurement signals as the reporting content; (3) taking the measurement information corresponding to the beam measurement signal of the target position in the first sort as the reporting content; the first sort refers to the sorting of beam measurement signals according to the measurement information corresponding to the beam measurement signal; (4) taking the measurement information corresponding to the beam measurement signal that meets the first measurement index condition as the reporting content. This can specifically clarify the reporting content determination rule. Regarding item (1), the service device can be determined by the second network device according to the weight sorting corresponding to the first network device; for example, item (1) is implemented as follows: select one or more RIS with the best weight sorting as the service RIS, and select one or more beam measurement information corresponding to each RIS for reporting. Regarding item (3), the target position refers to the sorting position of the beam measurement signals; item (3) can also be: the measurement information corresponding to the beam measurement signals ranked at the target position in the first sort is used as the reporting content; wherein, the first sort can refer to the sorting of beam measurement signals according to the measurement information corresponding to each beam measurement signal; for example, item (3) is implemented as: the measurement information corresponding to the best beam measurement signals (signal quality or channel state) is selected according to the sort and reported; but it is not limited to this. Among them, the first measurement index conditions are, for example: the reference signal received power RSRP is greater than the third threshold; and / or, the channel state information CSI meets the target requirements of the terminal; and / or, the block error rate BLER is less than the fourth threshold, etc.

[0226] Furthermore, the beamforming determination method further includes: receiving a first notification sent by the second network device based on the target measurement information; the first notification is used to indicate the serving beam, or to indicate a change in the serving beam. This allows the terminal to accurately know the relevant information about the serving beam. In this solution, the first notification may be followed by: performing a corresponding operation based on the first notification; however, this is not a limitation.

[0227] In this embodiment of the application, the beamforming determination method further includes: receiving a second notification sent by the second network device, the second notification indicating a candidate serving beam; the step of measuring at least two beam measurement signals sent by at least two first network devices to obtain measurement information includes: measuring at least two beam measurement signals sent by at least two first network devices according to the second notification to obtain measurement information; the at least two beam measurement signals are beam measurement signals corresponding to the candidate serving beam. This allows for accurate identification of the candidate serving beam and corresponding signal measurements, supporting the second network device in selecting the serving beam of the terminal. The phrase "measuring at least two beam measurement signals sent by at least two first network devices according to the second notification to obtain measurement information" can be implemented as: measuring at least two beam measurement signals sent by at least two first network devices respectively according to the second notification to obtain measurement information; however, it is not limited to this.

[0228] This application also provides a beamforming determination method, applied to a first network device, such as... Figure 4 As shown, it includes:

[0229] Step 41: Send at least one beam measurement signal; the beam measurement signal is associated with a beam in a first region.

[0230] Step 41 may include: sending at least two beam measurement signals; the beam measurement signal is uniquely associated with a beam in a first region, but is not limited to this. Specifically, it can be implemented as follows: each first network device has multiple beams; during UE measurement, each first network device sends one beam at a time, and the UE receives the measurement signal of one beam from each of the two first network devices (i.e., beam measurement signals); or, the UE receives only the measurement signals of two beams from one first network device (i.e., beam measurement signals), which is not limited here; it can also be understood that the UE measures the beam measurement signals within a given time period, and depending on the length of the given time, it will receive different numbers of measurement signals. These measurement signals may be signals from the same first network device associated with different beams, or signals from different first network devices associated with different beams.

[0231] The beamforming determination method provided in this application embodiment transmits at least one beam measurement signal; the beam measurement signal is associated with a beam in a first region; it can support determining the serving beam of the terminal based on the measurement information measured by the terminal (for example, selecting the beam with better channel quality and less interference to other terminals corresponding to the terminal as the serving beam, or selecting the beam with the best channel quality corresponding to the terminal as the serving beam, and further processing the interference beam of the terminal, etc.), so as to reduce interference conflicts, improve system performance, and support solving the problem in the prior art where multiple RIS beams serve multiple UEs and the RIS beams interfere with non-target UEs.

[0232] Furthermore, the beamforming determination method further includes: receiving a third notification sent by the second network device; the third notification instructing the first network device to enter a shutdown state, a beam absorption state, or a diffuse scattering state; and entering the shutdown state, beam absorption state, or diffuse scattering state according to the third notification. This allows the first network device to be shut down as needed, achieving a certain energy-saving effect.

[0233] This application also provides a beamforming determination method, applied to a second network device, such as... Figure 5 As shown, it includes:

[0234] Step 51: Receive target measurement information sent by at least one terminal, the target measurement information including at least a portion of measurement information, the measurement information being obtained by measuring at least two beam measurement signals sent by at least two first network devices; the beam measurement signals are associated with a beam in a first region; the measurement information includes: channel information corresponding to the beam measurement signal, or, at least one channel information corresponding to the beam measurement signal and at least one interference information corresponding to the beam measurement signal.

[0235] The second network device can be implemented as a base station, but is not limited thereto; step 51 may include: receiving target measurement information sent by at least one terminal, the target measurement information including at least a portion of measurement information, the measurement information being obtained by measuring at least two beam measurement signals sent by at least two first network devices respectively; the beam measurement signal being uniquely associated with a beam in a first region; the measurement information including: channel information corresponding to each of the beam measurement signals, or, channel information corresponding to at least one of the beam measurement signals and interference information corresponding to at least one of the beam measurement signals; but is not limited thereto.

[0236] Step 52: Determine the service beam of the terminal based on the target measurement information.

[0237] Step 52 may include: determining the service beam of each terminal based on the target measurement information; however, it is not limited to this.

[0238] The beamforming determination method provided in this application receives target measurement information sent by at least one terminal. The target measurement information includes at least a portion of the measurement information, which is obtained by measuring at least two beam measurement signals sent by at least two first network devices. The beam measurement signals are associated with a beam in a first region. The measurement information includes: channel information corresponding to the beam measurement signal, or at least one channel information corresponding to the beam measurement signal and at least one interference information corresponding to the beam measurement signal. Based on the target measurement information, the serving beam of the terminal is determined. This method can support determining the serving beam of the terminal based on the measurement information measured by the terminal (e.g., selecting a beam with better channel quality and less interference to other terminals as the serving beam, or selecting the beam with the best channel quality corresponding to the terminal as the serving beam, and further processing the interference beam of the terminal, etc.), so as to reduce interference conflicts, improve system performance, and support solving the problem in the prior art where multiple RIS beams serving multiple UEs cause interference to non-target UEs.

[0239] For scenarios where the UE has not determined its serving device, determining the terminal's serving beam based on the target measurement information may include: when the target measurement information sent by the terminal includes channel information corresponding to at least one beam measurement signal, obtaining a first weight of the first beam corresponding to the beam measurement signal of the terminal based on the target measurement information; obtaining the sum of the first weights of the first beams belonging to the target network device as a second weight of the target network device; the target network device refers to the first network device to which the first beam belongs; selecting the terminal's serving device from the target network devices based on the second weight; selecting the terminal's serving beam from the first beams under the serving device based on the second weight corresponding to the serving device and the first weight of the corresponding first beam; and sending a first notification indicating the serving beam to the terminal. This can accurately determine the terminal's serving device and inform the terminal. Regarding the acquisition of the first weight, it can be implemented as follows: the (beam) measurement signal is associated with the first beam; the target measurement information corresponding to the measurement signal indicates that a good measurement result corresponds to a high beam weight, and a poor measurement result corresponds to a low beam weight, but this is not a limitation. Regarding the second weight, specifically for example: for a certain UE, the second weight of the first network device is obtained by summing the first weights of multiple first beams under the same first network device, but it is not limited to this. "Selecting the serving device of the terminal from the target network devices according to the second weight" can include: obtaining the second weight with the highest value, and using the target network device corresponding to the obtained second weight as the serving device of the terminal, but it is not limited to this.

[0240] The step of selecting the service beam of the terminal from the first beam under the service device according to the second weight corresponding to the service device and the first weight corresponding to the first beam includes: for at least one terminal that uses the same first network device as a service device, sorting the terminals according to the second weight corresponding to the terminal to obtain a sorting result; and selecting the service beam of the terminal according to the sorting result and the first weight of the first beam corresponding to the terminal under the service device; wherein the first beam serves as the service beam of at least one terminal. This allows for accurate selection of the service beam of the terminal. The phrase "for at least one terminal that uses the same first network device as a service device, sorting the terminals according to the second weight corresponding to the terminal to obtain a sorting result" can include: for at least one terminal that uses the same first network device as a service device, sorting the terminals according to the second weight corresponding to each terminal to obtain a sorting result; however, it is not limited to this.

[0241] The phrase "selecting a service beam for a terminal based on the sorting result and the first weight of the first beam corresponding to the terminal under the service device" can include: selecting a service beam for a terminal based on the sorting result and the first weight of each first beam corresponding to the terminal under the service device. Specifically, "selecting a service beam for a terminal based on the sorting result and the first weight of each first beam corresponding to the terminal under the service device" can be implemented as follows: selecting a service beam from the first beams under the service device for each terminal in sequence according to the sorting result using a first method; the first method includes: selecting a service beam based on the first weight of each first beam corresponding to the terminal under the service device (for example, selecting the first beam corresponding to the largest first weight as the service beam); and / or, "the first beam serves as the service beam for at least one terminal" can be implemented as follows: one first beam can serve as the service beam for at least one terminal (which can be understood as one first beam serving one or more UEs), which is not limited here.

[0242] In the scenario where the UE determines the serving device, when the measurement information includes the channel information corresponding to the serving device of the terminal and the interference information corresponding to the non-serving device, and the channel information meets the transmission requirements of the terminal, the step of determining the serving beam of the terminal based on the target measurement information includes: (1) obtaining the third weight of the beam in the beam pool of the serving device based on the channel information; selecting the serving beam of the terminal in the beam pool of the serving device based on the third weight; and obtaining the first interference factor (also understood as interference weight) of the second beam corresponding to the beam measurement signal of the terminal based on the interference information; the second beam is the beam under the non-serving device; removing at least one beam in the beam pool of the first network device that is a non-serving device based on the first interference factor greater than the second threshold (in this scheme, there may not be a first interference factor greater than the second threshold, in which case the beam removal operation may not be performed).

[0243] Alternatively, (2) based on the channel information and interference information, determine the service weight and interference weight corresponding to at least one third beam; the third beam is the beam corresponding to the channel information or interference information, the service weight refers to the weight corresponding to the third beam as the service beam of the terminal, and the interference weight refers to the weight corresponding to the third beam as the interference beam of the terminal; based on the service weight and interference weight, determine the service beam of the terminal.

[0244] This allows for accurate determination of the terminal's serving beam. The beam pool of the aforementioned serving device refers to the set of all beams containing the serving device; similarly, the beam pool of the first network device, which is a non-serving device, refers to the set of all beams containing the non-serving device, but is not limited thereto. Specifically, "removing at least one beam from the beam pool of the first network device, which is a non-serving device, based on the first interference factor greater than the second threshold" can be implemented by removing one or more beams that satisfy predefined conditions for the interference factor (e.g., satisfying a certain threshold or having the maximum interference factor) from their corresponding beam pools; that is, removing beams whose corresponding first interference factor satisfies the predefined conditions, but is not limited thereto. Wherein, “obtaining the third weight of the beams in the beam pool of the serving device according to the channel information” may include: obtaining the third weight of each beam in the beam pool of the serving device according to the channel information; and / or, the service weight refers to the weight corresponding to the third beam as a serving beam of a terminal, and the interference weight refers to the weight corresponding to the third beam as an interfering beam of a terminal; and / or, “determining the serving beam of the terminal according to the service weight and the interference weight” may include: determining the serving beam of each terminal according to the service weight and the interference weight, but is not limited thereto.

[0245] For scenario (1) where the UE determines the serving device, it can also be implemented as follows: First, assume there is a beam set (i.e., beam pool) of a first network device. Then, remove beams in this set whose interference factors do not meet the requirements (similar to removing at least one beam in the beam pool based on the first interference factor greater than the second threshold). Then, select the beam with the largest service weight for the target UE or whose service weight meets the requirements from the remaining set as the serving beam. After that, the determined serving beam can be notified to the first network device so that the first network device can use the beam for signal transmission. Here, the interference factor can be the interference factor for the target UE, or it can be understood as the interference factor corresponding to the target UE; specifically, the RIS beam selection process is for the UE, so the interference factor can be the interference factor for a specific UE, but it is not limited to this.

[0246] Taking the above scenario of UE determining the serving device as an example (2), it is assumed that: for UE1, if beam 1 is used as a serving beam, it has a service weight of 1; if it is used as an interference beam, it has an interference factor of 1; for UE2, if beam 1 is used as a serving beam, it has a service weight of 2; if it is used as an interference beam, it has an interference factor of 2; then when selecting the serving beam of beam 1, the service weight of 1 and the interference factor of 2 are considered; when selecting the serving beam of beam 2, the service weight of 2 and the interference factor of 1 are considered, but not limited to these.

[0247] The step of removing at least one beam from the beam pool of a first network device that is a non-serving device based on the first interference factor greater than a second threshold includes: removing at least one beam from the beam pool of a first network device that is a non-serving device based on the first interference factor greater than the second threshold among the first interference factors corresponding to all terminals in the first area (for example, performing beam removal operations separately for all first network devices in the first area); the beamforming determination method further includes: if all beams in the beam pool corresponding to a first network device have been removed, then sending a third notification to the corresponding first network device (i.e., the first network device where all beams in the beam pool have been removed); the third notification is used to instruct the first network device to enter a shutdown state, a beam absorption state, or a diffuse scattering state. This can support a certain degree of energy saving. The first network device can be directly controlled by the second network device, or it can be controlled by the second network device via signaling. The difference lies in whether there is a wired connection between the second and first network devices. Specifically, the first network device can be deployed independently, but it is controlled by the second network device. The signals sent by the second network device to the UE can be sent to the first network device via the air interface and then forwarded to the second network device. However, the control information of the second network device to control the first network device can be transmitted to the first network device via cable or air interface, which is not restricted here. The phrase "removing at least one beam from the beam pool of the first network device as a non-serving device based on the first interference factors greater than the second threshold corresponding to all terminals in the first area" can include: removing at least one beam from the beam pool of the first network device as a non-serving device based on the first interference factors greater than the second threshold corresponding to all terminals in the first area; however, it is not limited to this.

[0248] Furthermore, the beamforming determination method further includes: sending a first notification to the terminal, wherein the first notification is used to indicate the serving beam or to indicate a change in the serving beam. This allows the terminal to accurately know the relevant information about the serving beam.

[0249] In the scenario where the UE determines the serving device, and the measurement information includes the channel information corresponding to the serving device of the terminal and the interference information corresponding to the non-serving device, and the channel information does not meet the transmission requirements of the terminal, the beamforming determination method further includes: performing a first operation to obtain a candidate serving beam; sending a second notification to the terminal, the second notification being used to indicate the candidate serving beam; wherein, the first operation includes at least one of the following: (1) for the serving device, selecting a beam that meets a second condition as a candidate serving beam; the second condition includes: belonging to the serving device, and / or being adjacent to the current serving beam; (2) for the non-serving device, selecting a fourth beam corresponding to a second interference factor greater than a first threshold as a candidate serving beam; the fourth beam is the beam under the non-serving device, and the second interference factor is the interference factor indicated by the interference information corresponding to the fourth beam. This allows for accurate notification of candidate serving beams to the UE. Specifically, for example, the base station notifies the RIS and the UE of candidate serving beams. Subsequently, the UE can measure the corresponding beam (e.g., measure the candidate serving beam as the serving beam to obtain channel information, and measure the non-candidate serving beam as the non-serving beam to obtain interference information) and then feed it back to the base station. The base station ultimately selects the serving beam based on the information reported by the UE, but is not limited to this.

[0250] Furthermore, the beamforming determination method further includes: sending first configuration information to at least one terminal, the first configuration information being used to indicate reporting parameters for the measurement information, the reporting parameters including at least one of reporting timing and reporting content determination rules. This enables the terminal to accurately report relevant information.

[0251] The reporting content determination rule includes at least one of the following: (1) taking the measurement information corresponding to at least one beam measurement signal under at least one serving device as the reporting content; the serving device refers to the first network device corresponding to the serving beam and providing services to the terminal; (2) taking the measurement information corresponding to all received beam measurement signals as the reporting content; (3) taking the measurement information corresponding to the beam measurement signal of the target position in the first sort as the reporting content; the first sort refers to the sorting of beam measurement signals according to the measurement information corresponding to the beam measurement signals; (4) taking the measurement information corresponding to the beam measurement signal that meets the first measurement index condition as the reporting content. This can specifically clarify the reporting content determination rule.

[0252] It should be noted that the relevant content of the above-mentioned terminal, first network device side and second network device side can be referred to each other, and the repeated parts will not be repeated.

[0253] The beamforming determination method provided in the embodiments of this application will be illustrated below with examples. The first network device mentioned above is a RIS device, and the second network device is a base station.

[0254] To address the aforementioned technical problems, this application provides a beamforming determination method, specifically a multi-RIS (Reconfigurable Intelligence Surface) multi-beam measurement and interference coordination scheme (also understood as a multi-RIS multi-beam resource scheduling scheme). The method mainly involves: within a predefined time period, the UE measures the measurement signals of different beams from multiple associated RIS devices to obtain measurement information for the corresponding RIS beams (this can correspond to measuring at least two beam measurement signals sent by at least two first network devices within the first time period to obtain measurement information). This measurement information may include channel information and interference information (also understood as obtaining channel information and interference information for multiple beams from multiple RIS devices). The UE reports this information to the base station (this can correspond to sending target measurement information from the measurement information to the second network device; the target measurement information includes at least a portion of the measurement information). The base station adjusts the RIS beams based on the information reported by the UE to achieve interference coordination. Specifically, the base station can determine the phase shift matrix (i.e., beamforming) of the RIS based on the measurement information reported by multiple UEs. By adjusting the phase shift matrix of the RIS, the coverage range or coverage direction of the RIS can be adjusted, thereby avoiding interference between different UEs or cells.

[0255] The following provides specific examples illustrating the relevant content of this plan.

[0256] Regarding configurable and / or predefined related content:

[0257] 1. The RIS measurement signal and the RIS beam are associated one-to-one within a defined area (e.g., one cell or two or three adjacent cells) (which can correspond to the beam measurement signal being associated with the beam in the first area as described above). For example, the measurement signal sequence sent by RIS beam 1 (which can be understood as the original measurement sequence, associated with the beam; the UE can understand that this sequence can be associated with the corresponding beam) is "10001001", the measurement signal sequence sent by RIS beam 2 is "10001011", and so on.

[0258] 2. Predefined measurement time T (corresponding to the first time period mentioned above): During the measurement time T, the UE measures all RIS measurement signals received during this time period and records the corresponding measurement information.

[0259] 3. RIS measurement signals can be transmitted periodically, semi-periodically, or aperiodically. The transmission time indicator for the RIS measurement signal can be the nth slot (time slot) of a certain frame. For example, periodic transmission means periodically transmitting in the nth slot of multiple frames.

[0260] 4. A serving RIS is an RIS that provides services to the UE (forwards signals sent by the base station to the UE); a non-serving RIS is an RIS that does not provide services to the UE (forwards signals sent by the base station to other UEs).

[0261] 5. For a UE, each UE can select one or more RIS as the serving RIS, and within each RIS, one or more RIS beams can be selected as the serving RIS beams for that UE (corresponding to the serving beams mentioned above). Preferably, only one RIS beam is selected as the serving RIS beam for that UE. A serving beam refers to a beam that provides services to the UE, while a non-serving beam refers to a beam that does not provide services to the UE.

[0262] 6. The reporting rules for measurement information corresponding to RIS measurement signals (which may correspond to the rules for determining the reporting content mentioned above) can be determined based on base station configuration or predefined rules, including the following possibilities:

[0263] (1) Select one or more RIS with the best weights as serving RIS, and report the measurement information corresponding to one or more beams of each RIS; this corresponds to the above-mentioned reporting of the measurement information corresponding to at least one beam measurement signal under at least one serving device; the serving device refers to the first network device that corresponds to the serving beam and provides services to the terminal. Among them, the weights in the weight ranking are obtained as follows: the weights of multiple RIS beams under the same RIS device are normalized and superimposed to obtain the weight of the RIS device; the RIS beam weights are obtained by normalizing the measurement results of each measurement information (or beam).

[0264] (2) Report the measurement information corresponding to all received measurement signals; the measurement information corresponding to all received beam measurement signals can be reported as described above.

[0265] (3) Report the measurement information corresponding to the best beam measurement signals (signal quality or channel status) according to the sorting; this can correspond to the above-mentioned use of the measurement information corresponding to the beam measurement signals of the target positions in the first sorting as the reporting content; the first sorting refers to the sorting of beam measurement signals according to the measurement information corresponding to the beam measurement signals.

[0266] The measurement information corresponding to the RIS measurement signal may include one or more of the following: RIS indication, RIS beam indication, RIS measurement signal indication, and corresponding measurement results (such as at least one of RSRP (Reference Signal Receiving Power), CSI (Channel State Information), PMI (Pre-coding matrix Indication), BLER (Block Error Rate), etc.). If the measurement results are good, the corresponding RIS and the control matrix used can be used by the network side. This operation can also fall under the aforementioned "configurable and / or predefined related content." Specifically, if the measurement results are good, after the UE reports to the base station, the base station will select the corresponding RIS and beam (control) for signal transmission based on the measurement results. The selection can vary depending on interference conditions, choosing between multiple or one RIS, and is not limited here.

[0267] In the embodiments of this application, "RIS indication, RIS beam indication and / or RIS measurement signal indication" can be information indicating related identity, such as identity identifier. Specifically, for example, the RIS indication is used to indicate the identity information of the RIS (device) and can be any signaling or information that indicates the RIS, such as the RIS index; the RIS beam indication is used to indicate the identity information of the RIS beam, but is not limited thereto.

[0268] The measurement signal sequence can be determined and distinguished by combining RIS indicator + RIS beam indicator (the corresponding beam can be distinguished by combining RIS indicator + RIS beam indicator), or the measurement signal sequence can be determined and distinguished by combining RIS beam indicator (the corresponding beam can be distinguished by numbering all RIS beams together), which is not limited here.

[0269] 7. The timing of the UE reporting measurement information (corresponding to the above reporting timing) can be configured by the base station or determined according to a predefined time, such as the UE reporting in the next subframe after the predefined measurement time T ends.

[0270] The 6 and 7 under "Configurable and / or predefined related content" above can correspond to determining the reporting timing for sending the target measurement information to the second network device based on the reporting parameters indicated by the first configuration information, and / or determining the target measurement information; wherein, the first configuration information is predefined information or information indicated by the second network device. The reporting parameters include at least one of the reporting timing and reporting content determination rules.

[0271] Regarding the specific process:

[0272] I. RIS side:

[0273] 1. The RIS transmits measurement signals according to the base station configuration or predefined rules (which may correspond to transmitting at least one beam measurement signal as described above; the beam measurement signal is associated with a beam in the first region). The behavior of transmitting measurement signals can be:

[0274] (1) While forwarding the base station signal, the RIS modulates the signal and adds a measurement signal (e.g., uniformly adding a specific phase) and sends it to the UE.

[0275] (2) The RIS itself has a simple signal transmission function, such as reconfigurable distributed antennas and reflective surfaces (RDARS). The RSARS can be connected to the RRU (Remote Radio Unit) through a control circuit switching switch. It has a signal transmission function when connected to the RRU.

[0276] (3) Each RIS is equipped with a controller, which sends measurement signals that are forwarded by the RIS. The controller is very close to the RIS panel.

[0277] 2. The RIS adjusts the phase shift matrix according to the base station configuration or predefined rules and forwards the signals sent by the base station.

[0278] II. UE side:

[0279] Step 0: (Optional) The UE receives base station configuration information or notification information. For example, in a scenario where the base station determines to switch RIS based on the measurement information reported by the UE, the base station can notify the UE of the candidate RIS; subsequently, after receiving the base station notification, the UE can measure the candidate RIS and obtain the channel information of the candidate RIS.

[0280] Step 1: The UE receives and performs measurements (corresponding to the measurements of at least two beam measurement signals sent by at least two first network devices) at multiple RIS measurement signal reception times within the measurement time T, according to the base station configuration or predefined rules, and stores the measurement information. The measurement behavior may include the following two types:

[0281] 1) If the UE does not determine the serving RIS, measure all received RIS measurement signals to obtain channel information (e.g., at least one of RSRP, AOA (Azimuth of Arrival), ZOA (Zenith Angle of Arrival), RI (Rank Indicator), CSI, etc.).

[0282] 2) If the UE determines that the service RIS is being provided, the measurement shall perform at least one of the following operations:

[0283] a) Measure the measurement signal of the serving RIS to obtain channel information (e.g., at least one of RSRP, AOA, ZOA, RI, CSI, etc.) and measure the measurement signal of the non-serving RIS to obtain interference information (e.g., at least one of power, power ratio with the serving RIS measurement signal, RSRP, etc.).

[0284] b) Measure the measurement signal of the candidate (serving) RIS to obtain the channel information of the candidate RIS; measure the measurement signal of the non-candidate (serving) RIS to obtain the interference information (corresponding to the non-candidate RIS).

[0285] Step 2: The UE reports the measured measurement information according to the base station configuration or predefined rules (which may correspond to the target measurement information in the measurement information sent to the second network device mentioned above). For the two situations shown in Step 1 above, the information reported by the UE may include the following two possibilities:

[0286] 1) The UE selects one or more beams of multiple RIS from the measurement information of all received RIS measurement signals according to the base station configuration or predefined rules and reports the measurement information to the base station (i.e., reports the measurement information of one or more beams of multiple RIS, the measurement information may include one or more of RIS indication, RIS beam indication, RIS measurement signal indication and corresponding measurement results (e.g., at least one of RSRP, CSI, PMI, BLER and other information), an example is shown in the table below.

[0287] RIS Beam Indicator Measurement results RIS1 BF1 (corresponding to measurement signal 1) RSRP1 RIS1 BF2 (corresponding to measurement signal 2) RSRP2 RIS2 BF1 (corresponding to measurement signal 3) RSRP3 RIS2 BF2 (corresponding to measurement signal 4) RSRP4 RIS3 BF1 (corresponding to measurement signal 5) RSRP5 RIS3 BF2 (corresponding to measurement signal 6) RSRP6

[0288] In this system, each measurement signal corresponds one-to-one with a RIS beam, and the UE determines the RIS (device) or RIS beam to be measured based on the received measurement signal. One method for mapping measurement signals to RIS and RIS beams is as follows:

[0289] The measurement signal includes RIS indication and RIS beam indication. For example, RIS1 BF1 (i.e., beam 1 of RIS device 1) is indicated as "0000", that is, the corresponding indication information of RIS1 BF1 in the beam measurement signal is "0000"; RIS1 BF2 is indicated as "0001", RIS2 BF1 is indicated as "0100", RIS2 BF2 is indicated as "0101", and so on.

[0290] The UE can then obtain the RIS and RIS beam indication based on the obtained measurement signals.

[0291] 2) The UE reports the channel information of the serving RIS (e.g., at least one of RSRP, AOA, ZOA, RI, CSI, etc.) and the interference information of the non-serving RIS to the UE (e.g., power, power ratio with the serving RIS measured signal, RSRP, etc.) according to the base station configuration or predefined rules.

[0292] One possible reporting rule, configured or predefined by the base station, is as follows: The UE selects measurement information corresponding to one or more RIS measurement signals that meet predefined conditions from all RIS measurement signals measured within a predefined time T, and reports this information to the base station at the nth symbol of the mth slot after the predefined time T ends. This corresponds to the above-mentioned reporting of measurement information corresponding to beam measurement signals that meet the first measurement index condition. Specifically, the UE can perform measurement reporting based on the base station configuration or according to predefined rules; this is not limited here.

[0293] Optionally, the predefined conditions (corresponding to the first measurement index conditions) may include at least one of the following:

[0294] 1) RSRP is greater than a certain predefined threshold; this can be understood as, depending on the specific implementation, RSRP is made to be greater than a certain threshold, which can be configured by the base station; the UE determines whether this condition is met based on the measurement results.

[0295] 2) CSI meets the target UE's requirements, which can be a threshold related to the requirements configured by the base station. The requirements can be determined by the UE itself or configured by the network. The target requirements can be determined based on service requirements and UE capabilities. CSI can be reflected through PMI or RI. Here, the target UE is the UE performing the measurement. Regarding "CSI meets the target UE's requirements", for example, if the CSI feedback is RI, and the UE's specific requirement is to transmit 2 streams, then an RI greater than or equal to 2 fed back by the CSI can be considered to meet the requirements, but it is not a limitation. 3) BLER is less than a certain threshold.

[0296] Step 3: (Optional) The UE receives a notification from the base station. For example, the base station indicates the serving beam or switches the serving beam (which may correspond to receiving the first notification sent by the second network device based on the target measurement information; the first notification is used to indicate the serving beam or to indicate changing the serving beam); or, the base station notifies the candidate beams that need further measurement to assist the base station in determining the final serving beam; which may correspond to receiving the second notification sent by the second network device, the second notification being used to indicate the candidate serving beam; according to the second notification, measurements are performed on at least two beam measurement signals sent by at least two first network devices to obtain measurement information; the at least two beam measurement signals are the beam measurement signals corresponding to the candidate serving beams.

[0297] III. Base station side:

[0298] Step 0 (optional): The base station configures the RIS measurement signal transmission method (periodic or aperiodic, etc.) and transmission timing for the RIS and UE (e.g., configure the reception timing for the UE). The base station can also configure the rules for the UE to report measurement information (e.g., reporting timing, format, etc.).

[0299] Of course, Step 0 can also be omitted in this scheme, and RIS and UE can operate according to predefined rules, which is not limited here.

[0300] Step 1: The base station receives the measurement information reported by the UE and performs the following two operations:

[0301] 1) In the case where the UE has not determined the serving RIS, the measurement information reported by the UE is the measurement information that the UE selects from all the RIS measurement signals received, according to predefined rules or base station configuration, and meets the predefined conditions (which may include one or more of the following: RIS indication, RIS beam indication, RIS measurement signal indication, and corresponding measurement results (e.g., at least one of RSRP, CSI, PMI, BLEE, etc.)). Based on this information, the serving RIS and serving RIS beam of the UE are determined according to the predefined rules; this may correspond to the above-mentioned receiving of target measurement information sent by at least one terminal; and the serving beam of the terminal is determined based on the target measurement information.

[0302] a) A possible service RIS selection method includes: classifying measurement results of different beams under the same RIS based on information reported by the UE, using the RIS index as a label. Classifying measurement information reported by different UEs by RIS device, using the RIS index as a label, i.e., classifying different UEs covered by the same RIS device. Measurement information reported by the same UE is labeled by UE, and weights are calculated for the RIS beams corresponding to different measurement signals under the same UE based on the measurement information (this can correspond to the above-mentioned case where the target measurement information sent by the terminal includes channel information corresponding to at least one beam measurement signal, obtaining the first weight of the first beam corresponding to the beam measurement signal of the terminal based on the target measurement information). Measurement signals are associated with RIS beams; RIS beams with better measurement results have higher weights, and RIS beams with poorer measurement results have lower weights.

[0303] For a given UE, the weights of multiple RIS beams under the same RIS device are normalized and superimposed to obtain the weight of that RIS device. This corresponds to the sum of the first weights of the first beam belonging to the target network device, which is used as the second weight of the target network device. The target network device refers to the first network device to which the first beam belongs. The aforementioned beam weights can be directly represented by measurement results. Regarding "normalizing and superimposing the weights," this can be achieved by directly normalizing the sum of the beam weights corresponding to each RIS device to obtain the weight of the RIS device corresponding to the UR. Alternatively, normalization can be performed directly during beam weight calculation, and the weight of the RIS device can then be obtained by simply summing the beam weights. It can be understood that the weight normalization operation in this application can be performed before (when obtaining beam weights) or after (when obtaining device weights), and is not limited here.

[0304] Then, the RIS device with the highest weight can be selected as the serving RIS device based on the RIS device weight; after selecting the serving RIS device, the serving RIS beam under that RIS device is selected; corresponding to the above, the serving device of the terminal can be selected from the target network devices based on the second weight; based on the second weight corresponding to the serving device and the first weight of the corresponding first beam, the serving beam of the terminal can be selected from the first beam under the serving device. Specifically, the selection process can employ at least one of the following:

[0305] i. Multiple UEs under the same serving RIS device are sorted according to the RIS device weight. UEs with larger RIS device weights (corresponding to the UE) have higher priority, and those with smaller RIS device weights have lower priority. UEs with higher priority first select a beam, choosing the beam with the largest weight as the serving beam. This beam is then removed from the beam pool (corresponding to the RIS device). The next UE with higher priority continues to select the beam with the largest weight from the beam pool, and the selected beam is removed from the beam pool. This process continues until all UEs have completed their selections or the beam pool is cleared. This process corresponds to the above-mentioned process for at least one terminal using the same first network device as a serving device, where the terminals are sorted according to the second weight corresponding to the terminal to obtain a sorting result; the serving beam for the terminal is selected based on the sorting result and the first weight of the first beam corresponding to the terminal under the serving device; wherein, the first beam serves as the serving beam for one terminal (i.e., each beam serves one UE).

[0306] ii. Under the same serving RIS device, multiple UEs are sorted according to the RIS device weight. UEs with higher RIS device weights have higher priority, and those with lower RIS device weights have lower priority. A predefined UE selection count is used, with one count for each beam. If one UE selects a beam, it is counted as 1; if two UEs select the beam, it is counted as 2, and so on. The initial value of the UE selection count for all beams is 0. The UE with the highest priority selects a beam first, choosing the beam with the highest weight as the serving beam. Then, the UE selection count for that beam is incremented by 1. When the UE selection count for that beam equals N, the beam is removed from the beam pool. The next UE with the next higher priority continues to select the beam with the highest weight for it from the beam pool. The UE selection count for the selected beam is incremented by 1. When the UE selection count for that beam equals N, the beam is removed from the beam pool. The next UE continues the selection process until all UEs have completed their selections or the beam pool is cleared. This process can correspond to the above-mentioned process for at least one terminal that uses the same first network device as a service device, sorting the terminals according to the second weight corresponding to the terminal to obtain a sorting result; selecting the service beam of the terminal according to the sorting result and the first weight of the first beam corresponding to the terminal under the service device; wherein, the first beam serves as the service beam of at least two terminals (i.e., each beam serves N UEs).

[0307] 2) The UE determines the serving RIS and receives measurement information reported by the UE, which includes channel information of the serving RIS and interference information of the non-serving RIS. Based on this information, the following two situations arise:

[0308] a) The serving RIS channel information meets the signal transmission requirements for providing services to the target UE. The phase shift matrix of the non-serving RIS is adjusted according to the interference information of the non-serving RIS to reduce the interference of the non-serving RIS to the target UE. Specifically, the following methods can be used: i) (eliminating interference and selecting the serving beam from the serving device); or ii) (not eliminating interference and directly selecting the serving beam from all beams based on the interference situation of each UE; for example, beam 1 and interfering beam 2 under the serving RIS device of UE1 are both interfering beams of UE2, but the signal quality of beam 1 and beam 2 is similar for UE1, while the interference of beam 1 to UE2 is greater than that of beam 2, so beam 2 is selected as the serving beam of UE1, but this is not a limitation.

[0309] i. Calculate the interference factor (corresponding to the first interference factor mentioned above) for the RIS beams corresponding to different measurement signals under the same UE based on the measurement information (including interference information). The measurement signal is associated with the RIS beam; the RIS beam with stronger interference has a larger interference factor, and the RIS beam with weaker interference has a smaller interference factor (similar to the beam weight calculation mentioned above). For a certain UE, remove one or more beams whose interference factor for the UE meets predefined conditions (e.g., meets a certain threshold or has the largest interference factor) from the beam pool of that RIS. Calculate the interference factor for all UEs in the region (i.e., the uniquely associated region of the measurement signal, corresponding to the first region mentioned above) in turn, and remove the beams whose interference factor meets the threshold from each RIS beam pool. The value of the beam; this part of the operation can correspond to the above-mentioned obtaining the first interference factor of the second beam corresponding to the beam measurement signal of the terminal based on the interference information; the second beam is the beam under the non-serving device; according to the first interference factor greater than the second threshold, remove at least one beam in the beam pool of the first network device as a non-serving device; the removal of at least one beam in the beam pool of the first network device as a non-serving device according to the first interference factor greater than the second threshold includes: removing at least one beam in the beam pool of the first network device as a non-serving device according to the first interference factor greater than the second threshold among the first interference factors corresponding to all terminals in the first area.

[0310] When a beam in the beam pool of a certain (RIS device) is cleared, the RIS is turned off (e.g., it enters a shutdown state, a beam absorption state, or a diffuse scattering state); corresponding to the above situation where all beams in the beam pool corresponding to the first network device are removed, a third notification is sent to the corresponding first network device; the third notification is used to instruct the first network device to enter a shutdown state, a beam absorption state, or a diffuse scattering state.

[0311] In this method, the RIS beam weight can also be calculated based on the measurement information (including channel information) of the serving RIS reported by the UE, and the beam with the largest weight can be selected as the serving beam from the beam pool of the serving RIS. This corresponds to obtaining the third weight of the beam in the beam pool of the serving device based on the channel information, and selecting the serving beam of the terminal from the beam pool of the serving device based on the third weight.

[0312] ii. Calculate the interference factor (corresponding to the interference weight mentioned above) for the RIS beams corresponding to different measurement signals under the same UE based on the measurement information (including interference information). The measurement signal is associated with the RIS beam; the RIS beam with stronger measured interference has a larger interference factor, and the RIS beam with weaker measured interference has a smaller interference factor. For a given UE, each RIS beam has an interference factor and a service weight. Select the beam whose interference factor and service weight satisfy a predefined rule (e.g., the beam with the smallest interference factor under the service weight threshold, or the beam with the largest service weight under the interference factor threshold) as the service beam for that UE. This method corresponds to determining the service weight and interference weight corresponding to at least one third beam based on the channel information and interference information; the third beam is the beam corresponding to the channel information or interference information, the service weight refers to the weight corresponding to the third beam as the service beam of the terminal, and the interference weight refers to the weight corresponding to the third beam as the interference beam of the terminal; determine the service beam of the terminal based on the service weight and interference weight. The acquisition of service weights can refer to the acquisition of RIS beam weights in 1); for example, when a measurement signal is associated with a RIS beam, the RIS beam with better measurement results has a higher weight, and the RIS beam with poor measurement results has a lower weight, but this is not a limitation. This method can avoid having to select beams that cannot meet the requirements from the serving device as the service beam.

[0313] Regarding the example of method ii, assume: For UE1, beam 1 has a service weight of 1 if it is used as a serving beam, and an interference factor of 1 if it is used as an interfering beam; For UE2, beam 1 has a service weight of 2 if it is used as a serving beam, and an interference factor of 2 if it is used as an interfering beam; When selecting the serving beam for UE1, service weight 1 and interference factor 2 are considered; When selecting the serving beam for UE2, service weight 2 and interference factor 1 are considered, but this is not a limitation.

[0314] b) If the serving RIS channel information does not meet the signal transmission requirements for providing service to the target UE, and interference information from non-serving RIS channels is used, a candidate serving RIS beam is selected (this can correspond to performing the first operation described above to obtain the candidate serving beam). For example:

[0315] i. For a serving RIS device, select a RIS beam that meets predefined conditions (e.g., all beams of the RIS, one or more RIS beams adjacent to the currently serving RIS beam, etc.) as a candidate serving RIS beam; corresponding to the above for the serving device, select a beam that meets a second condition as a candidate serving beam; the second condition includes: belonging to the serving device, and / or being adjacent to the currently serving beam.

[0316] ii. For non-serving RIS devices, select one or more RIS beams with an interference factor greater than a certain threshold as candidate RIS beams; corresponding to the above for the non-serving device, select a fourth beam corresponding to a second interference factor greater than a first threshold as a candidate serving beam; the fourth beam is the beam under the non-serving device, and the second interference factor is the interference factor indicated by the interference information corresponding to the fourth beam.

[0317] Step 2: The base station sends a configuration signaling notification to the UE of the selected service RIS (for 1) or candidate RIS (for 2) in b); it may correspond to sending a first notification to the terminal as described above, the first notification being used to indicate the service beam or to indicate the change of service beam; or, sending a second notification to the terminal, the second notification being used to indicate the candidate service beam.

[0318] In summary, this solution can resolve the interference problem among multiple users in a RIS-based MU-MIMO system. Specifically, by configuring the measurement signal, it can support beamforming adjustment based on the measurement information reported by the UE, thereby improving system performance and reducing interference conflicts.

[0319] This application also provides a beamforming determination device, which is a terminal, such as... Figure 6 As shown, it includes a memory 61, a transceiver 62, and a processor 63:

[0320] Memory 61 is used to store computer programs; transceiver 62 is used to send and receive data under the control of processor 63; processor 63 is used to read the computer programs in memory 61 and perform the following operations:

[0321] Measurement information is obtained by measuring at least two beam measurement signals sent by at least two first network devices; the beam measurement signals are associated with beams in a first region; the measurement information includes: channel information corresponding to the beam measurement signals, or at least one channel information corresponding to the beam measurement signals and at least one interference information corresponding to the beam measurement signals;

[0322] The transceiver 62 transmits the target measurement information from the measurement information to the second network device; the target measurement information includes at least a portion of the information in the measurement information.

[0323] The beamforming determination device provided in this application embodiment measures at least two beam measurement signals sent by at least two first network devices to obtain measurement information; the beam measurement signals are associated with beams in a first region; the measurement information includes: channel information corresponding to the beam measurement signals, or at least one channel information corresponding to the beam measurement signals and at least one interference information corresponding to the beam measurement signals; the device sends target measurement information from the measurement information to a second network device; the target measurement information includes at least a portion of the information in the measurement information; it can support determining the serving beam of a terminal based on the measurement information measured by the terminal (for example, selecting the beam with better channel quality and less interference to other terminals as the serving beam, or selecting the beam with the best channel quality corresponding to the terminal as the serving beam, and further processing the interference beam of the terminal, etc.), so as to reduce interference conflicts, improve system performance, and support solving the problem in the prior art where multiple RIS beams serve multiple UEs and the RIS beams interfere with non-target UEs.
