Description

Beamforming determination method, device, equipment and non-transient readable storage medium

[0001] The present disclosure claims priority to the Chinese patent application No. 202411327496.3, filed on September 23, 2024, entitled "Beamforming determination method, device, equipment and non-transient readable storage medium", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present disclosure relates to the field of communication technology, and in particular to a beamforming determination method, device, equipment and non-transient readable storage medium. BACKGROUND

[0003] In a wireless communication system based on a Reconfigurable Intelligence Surface (RIS), on the one hand, through the RIS device deployed between the base station and the terminal user, a line-of-sight link can be dynamically established on demand in a blind area or at the edge of a cell where the line-of-sight communication is not available or the signal quality is poor, thereby improving the network coverage quality and reducing the coverage blind area. On the other hand, a distributed multipoint transmission can be constructed by using distributed RIS nodes to obtain higher diversity or multiplexing (and / or beamforming) gain. However, since the RIS is a passive device (cannot process the forwarded signal), the signal of the working frequency band is directly forwarded (such as transmission, reflection, etc.), and all signals arriving at the RIS will be forwarded. Therefore, in the above cases, for a multi-RIS multi-user equipment or terminal (User Equipment, UE) system, the signal forwarded by the RIS beam may be a useful signal for UE1, but it is an interference signal for UE2 (UE2 refers to other UEs except UE1), that is, the RIS beam may cause interference to non-target UEs (such as UE2).

Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names.

[0211] First, the contents related to the scheme provided by the embodiments of the present disclosure are introduced as follows.

[0212] For a single RIS system, the coverage range or direction of the RIS can be fixed in a certain area statically or semi-statically, a fixed virtual link is established, and the system performance is improved. However, the following problems exist:

[0213] For a multi-UE wireless communication system based on multiple RISs as shown in FIG. 2, in addition to considering the coverage of signals, the interference problem between multiple RISs and multiple UEs also needs to be considered. At present, there is only a coverage enhancement scheme for a single RIS single UE system, and there is no effective and feasible interference coordination scheme for multiple RISs and multiple beams.

[0214] In addition, the coverage enhancement scheme for a single RIS or a single UE is not applicable to interference coordination scheduling in the case of multiple RISs and multiple beams. For a multi-RIS multi-beam system, how to adjust the phase shift matrix of multiple RISs (that is, adjust the RIS beam) to provide fair and consistent services for multiple UEs (or improve the cell capacity) is a problem that needs to be solved. To this end, the coverage direction and range of different RIS beam signals need to be reasonably coordinated to reduce the interference between different UEs and improve the system performance.

[0215] Based on the above, the embodiments of the present disclosure provide a beamforming determination method, apparatus, device and non-transitory readable storage medium to solve the problem that in the related art, in the scenario of multiple RIS beams serving multiple UEs, the RIS beams can cause interference to non-target UEs. The method, apparatus, device and non-transitory readable storage medium are based on the same application concept. Since the principles of the method, apparatus, device and non-transitory readable storage medium for solving the problem are similar, the implementation of the method, apparatus, device and non-transitory readable storage medium can be mutually referred to, and the repeated parts will not be described again.

[0221] Wherein, the at least part of the information can include measurement information of at least part of the number of beam measurement signals; but not limited thereto.

[0222] The beamforming determination method provided in the embodiments of the present disclosure can measure at least two beam measurement signals transmitted by at least two first network devices to obtain measurement information; the beam measurement signals are associated with beams in a first area; the measurement information includes channel information corresponding to 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; target measurement information in the measurement information is transmitted to a second network device; the target measurement information includes at least part of the measurement information; the target measurement information can support determining a serving beam of a terminal according to the measurement information measured by the terminal (for example, selecting a beam corresponding to the terminal as a serving beam, the beam having better channel quality and smaller interference to other terminals, or selecting a beam corresponding to the terminal as a serving beam, the beam having the best channel quality, and further processing an interference beam of the terminal), so as to reduce interference conflicts, improve system performance, and support solving the problem that RIS beams in a scenario in which multiple RIS beams serve multiple UEs in related technologies cause interference to non-target UEs.

[0223] In the embodiments of the present disclosure, the measurement of the at least two beam measurement signals transmitted by the at least two first network devices to obtain the measurement information includes: measuring the at least two beam measurement signals transmitted by the at least two first network devices in a first time period to obtain the measurement information.

The second network device can be implemented as a base station; and / or the reporting time is, for example, reporting at the nth symbol of the mth slot after the end of the measurement time T; and / or determining the target measurement information can include: determining the target measurement information according to a reporting content determination rule, but is not limited thereto.

[0225] The reporting parameter includes at least one of the reporting time and a reporting content determination rule. In this way, accurate determination and reporting of the target measurement information can be supported.

[0226] In the embodiments of the present disclosure, 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 a first network device corresponding to a service beam and providing services for 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 at the target position in the first sorting as the reporting content; the first sorting refers to the sorting of the 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 satisfying the first measurement index condition as the reporting content. In this way, the reporting content determination rule can be specified. Regarding item (1), the service device therein 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: selecting the best one or more RIS as the service RIS according to the weight sorting, and selecting the measurement information corresponding to one or more beams for each RIS for reporting. Regarding item (3), the target position therein refers to the sorting position of the beam measurement signal; item (3) can also be: taking the measurement information corresponding to the beam measurement signal at the target position in the first sorting as the reporting content; wherein the first sorting can refer to the sorting of the beam measurement signals according to the measurement information corresponding to each beam measurement signal; for example, item (3) is implemented as: selecting the measurement information corresponding to the best several beam measurement signals (in terms of signal quality or channel state) for reporting according to the sorting; but not limited thereto. The first measurement index condition, for example: the reference signal receiving power RSRP is greater than a third threshold; and / or, the channel state information CSI satisfies the target demand of the terminal; and / or, the block error rate BLER is less than a fourth threshold, and the like.

[0227] Further, the beamforming determination method further includes: receiving a first notification sent by the second network device according to the target measurement information; the first notification is used to indicate the service beam, or to indicate to replace the service beam. In this way, the terminal can accurately know the related content of the service beam. In this scheme, after the first notification, the corresponding operation can also be performed according to the first notification; but not limited thereto.

[0228] In the embodiments of the present disclosure, the beamforming determination method further includes: receiving a second notification sent by the second network device, the second notification being used for indicating a candidate serving beam; and measuring at least two beam measurement signals sent by the at least two first network devices to obtain measurement information, including: measuring at least two beam measurement signals sent by the at least two first network devices according to the second notification to obtain measurement information; and the at least two beam measurement signals are beam measurement signals corresponding to the candidate serving beam. In this way, the candidate serving beam can be accurately obtained and corresponding signal measurement can be performed to support the second network device to select a serving beam of the terminal. The "measuring at least two beam measurement signals sent by the 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 the at least two first network devices respectively according to the second notification to obtain measurement information, but is not limited thereto.

[0229] The embodiments of the present disclosure further provide a beamforming determination method applied to a first network device, as shown in FIG. 4, including:

[0230] Step 41: sending at least one beam measurement signal; the beam measurement signal is associated with a beam in a first area.

[0231] The step 41 can include: sending at least two beam measurement signals; the beam measurement signal is uniquely associated with a beam in the first area, but is not limited thereto. In addition, it can be specifically implemented as: each first network device has multiple beams; when the UE measures, each first network device sends one beam at a time, and the UE receives the measurement signal (i.e., the beam measurement signal) of one beam of each first network device in the two first network devices; or the UE only receives the measurement signal (i.e., the beam measurement signal) of 2 beams of one first network device, which is not limited herein; it can also be understood that the UE measures the beam measurement signal within a given time, and according to the length of the given time, different numbers of measurement signals will be received, which can be signals associated with different beams sent by the same first network device, or signals associated with different beams sent by different first network devices.

[0232] The beamforming determination method provided by the embodiments of the present disclosure can support determining the serving beam of the terminal according to the measurement information measured by the terminal (such as selecting the beam corresponding to the terminal as the serving beam, which has better channel quality and less interference to other terminals, or selecting the beam corresponding to the terminal as the serving beam, which has the best channel quality, and further processing the interference beam of the terminal, etc.), so as to reduce interference conflict, improve system performance, and support solving the problem that the RIS beam may cause interference to non-target UEs in the scenario that multiple RIS beams serve multiple UEs in the related art.

[0233] Further, the beamforming determination method further includes: receiving a third notification sent by a second network device; the third notification is used to indicate that the first network device enters a closed state, a wave-absorbing state or a diffuse scattering state; and according to the third notification, the first network device enters the closed state, the wave-absorbing state or the diffuse scattering state. In this way, the first network device can be closed according to the demand, so as to achieve a certain energy-saving effect.

[0234] The embodiments of the present disclosure further provide a beamforming determination method applied to a second network device, as shown in FIG. 5, which includes the following steps.

[0235] Step 51: receiving target measurement information sent by at least one terminal, the target measurement information including at least part 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 signal being associated with a beam in a first area; and the measurement information including channel information corresponding to the beam measurement signal, 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.

[0236] The second network device can be implemented as a base station, but is not limited thereto; and step 51 can include: receiving target measurement information sent by at least one terminal, the target measurement information including at least part of measurement information, the measurement information being obtained by measuring at least two beam measurement signals respectively sent by at least two first network devices; the beam measurement signal being uniquely associated with a beam in a first area; and 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.

[0237] Step 52: determining a serving beam of the terminal according to the target measurement information.

[0238] The step 52 can include: determining a serving beam of each terminal according to the target measurement information, but is not limited thereto.

[0239] The beamforming determination method provided by the embodiments of the present disclosure can receive target measurement information sent by at least one terminal, the target measurement information includes at least part of measurement information, the measurement information is obtained by measuring at least two beam measurement signals sent by at least two first network devices; the beam measurement signal is associated with a beam in a first area; the measurement information includes: channel information corresponding to the 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; determining a serving beam of the terminal according to the target measurement information; can support determining the serving beam of the terminal according to the measurement information measured by the terminal (such as selecting a beam corresponding to the terminal with better channel quality and less interference to other terminals as a serving beam, or selecting a beam corresponding to the terminal with the best channel quality as a serving beam, and further processing the interference beam of the terminal, etc.), to reduce interference conflict, improve system performance, and support solving the problem that the RIS beam in the related art causes interference to non-target UEs in the scenario of multiple RIS beams serving multiple UEs.

[0240] In a case where the target measurement information sent by the terminal includes channel information corresponding to at least one of the beam measurement signals, the determining of the serving beam of the terminal according to the target measurement information can include: obtaining a first weight of a first beam corresponding to the beam measurement signal corresponding to the terminal according to the target measurement information; obtaining a sum of the first weights of the first beams belonging to the target network device as a second weight of the target network device, wherein the target network device refers to a first network device to which the first beam belongs; selecting the serving device of the terminal from the target network device according to the second weight; selecting the serving beam of the terminal from the first beams under the serving device according to the second weight corresponding to the serving device and the first weight of the first beam corresponding to the serving device; and sending a first notification indicating the serving beam to the terminal. In this way, the serving device of the terminal can be accurately determined and the terminal can be informed. The obtaining of the first weight can be implemented in the following manner: the (beam) measurement signal is associated with the first beam, and the target measurement information corresponding to the measurement signal indicates that a higher beam weight corresponds to a better measurement result and a lower beam weight corresponds to a worse measurement result, but this is not a limitation. The second weight can be obtained in the following manner: for a certain UE, the second weight of the first network device is obtained according to the sum of the first weights of the first beams under the same first network device, but this is not a limitation. The selecting of the serving device of the terminal according to the second weight can include: obtaining the second weight with the highest value, and taking the target network device corresponding to the obtained second weight as the serving device of the terminal, but this is not a limitation.

[0241] The selecting of the serving beam of the terminal from the first beams under the serving device according to the second weight corresponding to the serving device and the first weight of the first beam corresponding to the serving device can include: for at least one terminal taking the same first network device as the serving device, ranking the terminals according to the second weights corresponding to the terminals to obtain a ranking result; and selecting the serving beam of the terminal according to the ranking 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 of the at least one terminal. In this way, the serving beam of the terminal can be accurately selected. The ranking of the terminals according to the second weights corresponding to the terminals can include: for at least one terminal taking the same first network device as the serving device, ranking the terminals according to the second weights corresponding to the terminals to obtain a ranking result, but this is not a limitation.

[0242] According to the sorting result and the first weight of each first beam corresponding to the terminal under the serving device, the selection of the serving beam of the terminal is performed; specifically, the selection of the serving beam of the terminal according to the sorting result and the first weight of each first beam corresponding to the terminal under the serving device can be implemented as follows: according to the sorting result, the first mode is used to select the serving beam from the first beam under the serving device for each terminal in turn; the first mode includes: selecting the serving beam according to the first weight of each first beam corresponding to the terminal under the serving device (for example, selecting the first beam corresponding to the first weight with the largest value as the serving beam); and / or, the first beam as the serving beam of at least one terminal can be implemented as follows: one first beam can serve as the serving beam of at least one terminal (that is, one first beam serves one or more UEs), which is not limited herein.

[0243] In the case that 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 requirement of the terminal, the determination of the serving beam of the terminal according to the target measurement information includes: (1) obtaining the third weight of the beam in the beam pool of the serving device according to the channel information; selecting the serving beam of the terminal in the beam pool of the serving device according to the third weight; and obtaining the first interference factor (which can also be understood as the interference weight) of the second beam corresponding to the beam measurement signal corresponding to the terminal according to 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 value, at least one beam in the beam pool of the first network device as the non-serving device is removed (in this scheme, there can be no first interference factor greater than the second threshold value, in which case the beam removal operation can not be performed);

[0244] Alternatively, (2) determining the service weight and the interference weight corresponding to at least one third beam according to the channel information and the interference information; the third beam is the beam corresponding to the channel information or the interference information, the service weight refers to the weight corresponding to the third beam as the serving beam of the terminal, and the interference weight refers to the weight corresponding to the third beam as the interference beam of the terminal; the serving beam of the terminal is determined according to the service weight and the interference weight.

[0245] Thus, the service beam of the terminal can be accurately determined. The beam pool of the service device refers to a set of all beams of the service device. Similarly, the beam pool of the first network device as a non-service device refers to a set of all beams of the non-service device, but is not limited thereto. The "removing at least one beam in the beam pool of the first network device as a non-service device according to the first interference factor greater than the second threshold" can be implemented by removing one or more beams from the corresponding beam pool when the interference factor meets a predefined condition (e.g., meets a certain threshold or the interference factor is maximum), that is, removing the beam whose corresponding first interference factor meets the predefined condition, but is not limited thereto. The "obtaining a third weight of the beam in the beam pool of the service device according to the channel information" can include: obtaining a third weight of each beam in the beam pool of the service device according to the channel information; and / or the service weight refers to a weight corresponding to the third beam as a service beam of a terminal, and the interference weight refers to a weight corresponding to the third beam as an interference beam of a terminal; and / or the "determining the service beam of the terminal according to the service weight and the interference weight" can include: determining the service beam of each terminal according to the service weight and the interference weight, but is not limited thereto.

[0246] For (1) in the scenario that the UE determines the service device, it can also be implemented by first assuming a beam set (i.e., a beam pool) of a first network device, then removing beams with non-compliant interference factors from the set (similar to the above "removing at least one beam in the beam pool according to the first interference factor greater than the second threshold"), and then selecting a beam with the maximum service weight or a service weight meeting the requirements in the remaining set as the service beam for the target UE. The determined service beam can be notified to the first network device, so that the first network device can use the beam for signal transmission. The interference factor can be the interference factor for the target UE, or 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 is not limited thereto.

[0247] For (2) in the scenario that the UE determines the service device, it is assumed that: beam 1 has a service weight 1 if it is a service beam for UE 1, and has an interference factor 1 if it is an interference beam; beam 1 has a service weight 2 if it is a service beam for UE 2, and has an interference factor 2 if it is an interference beam. When selecting the service beam of beam 1, the service weight 1 and the interference factor 2 are considered; when selecting the service beam of beam 2, the service weight 2 and the interference factor 1 are considered, but are not limited thereto.

[0248] The removing at least one beam in the beam pool of the first network device as a non-service device according to the first interference factors greater than the second threshold value includes: removing at least one beam in the beam pool of the first network device as a non-service device according to the first interference factors greater than the second threshold value corresponding to all terminals in the first area (for example, the beam removing operation can be performed for all first network devices in the first area respectively); the beamforming determination method further includes: if 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 (i.e., the first network device whose all beams in the beam pool are removed); the third notification is used to indicate that the first network device enters an off state, an absorbing state or a diffuse scattering state. In this way, energy saving to a certain extent can be supported. The first network device can be directly controlled by the second network device or controlled by the second network device through signaling. The difference lies in whether there is a wired connection between the second network device and the first network device. Specifically, the first network device can be independently deployed, but is controlled by the second network device. The signal sent by the second network device to the UE can be sent to the first network device through the air interface and then forwarded to the second network device. However, the control information of the second network device for controlling the first network device can be transmitted to the first network device through a cable or an air interface, which is not limited herein. The removing at least one beam in the beam pool of the first network device as a non-service device according to the first interference factors greater than the second threshold value corresponding to all terminals in the first area can include: removing at least one beam in the beam pool of the first network device as a non-service device according to the first interference factors greater than the second threshold value corresponding to all terminals in the first area respectively, but is not limited thereto.

[0249] Further, the beamforming determination method further includes: sending a first notification to the terminal, the first notification being used to indicate a service beam or to indicate to replace a service beam. In this way, the terminal can accurately know the related content of the service beam.

[0250] In the case that the measurement information comprises 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 requirement of the terminal, the beamforming determination method further comprises: performing a first operation to obtain a candidate serving beam; and sending a second notification to the terminal, the second notification being used to indicate the candidate serving beam; wherein the first operation comprises at least one of the following: (1) for the serving device, selecting a beam meeting a second condition as the candidate serving beam; the second condition comprises 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 the candidate serving beam; the fourth beam is a beam under the non-serving device, and the second interference factor is an interference factor corresponding to the fourth beam indicated by the interference information. In this way, the candidate serving beam can be accurately notified to the UE; specifically, for example, the base station notifies the RIS and the UE of the candidate serving beam; then, the UE can measure the corresponding beam (for example, measures the candidate serving beam as the serving beam to obtain the channel information, and measures the non-candidate serving beam as the non-serving beam to obtain the interference information), and then feeds back to the base station; the base station finally selects the serving beam according to the information reported by the UE, but is not limited thereto.

[0251] Further, the beamforming determination method further comprises: sending first configuration information to at least one terminal, the first configuration information being used to indicate a reporting parameter of the measurement information, the reporting parameter comprising at least one of a reporting occasion and a reporting content determination rule. In this way, the terminal can accurately report the related information.

[0252] The reporting content determination rule comprises 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 a first network device corresponding to a serving beam and providing services for 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 at the target position in the first sorting as the reporting content; the first sorting refers to the sorting of the beam measurement signal according to the measurement information corresponding to the beam measurement signal; (4) taking the measurement information corresponding to the beam measurement signal meeting a first measurement index condition as the reporting content. In this way, the reporting content determination rule can be specified.

[0253] Herein, the related content of the terminal, the first network device side and the second network device side can be mutually referred to, and the repeated parts will not be described again.

[0254] The beamforming determination method provided by the embodiments of the present disclosure is exemplified below, and the first network device is exemplified as an RIS device, and the second network device is exemplified as a base station.

[0255] To solve the above technical problems, the embodiments of the present disclosure provide a beamforming determination method, which can be implemented as a Reconfigurable Intelligence Surface (RIS) multi-beam measurement and interference coordination scheme (which can also be understood as a multi-RIS multi-beam resource scheduling scheme), mainly involving: within a predefined time, a UE measures a measurement signal of each of a plurality of associated RIS different beams to obtain measurement information of the corresponding RIS beam (which can correspond to the above measurement of at least two beam measurement signals transmitted by at least two first network devices in a first time period to obtain measurement information), which can include channel information and interference information (which can also be understood as obtaining channel information and interference information of a plurality of beams of a plurality of RIS devices); the UE reports the information to a base station (which can correspond to the above sending of target measurement information in the measurement information to the second network device; the target measurement information includes at least part of the measurement information). The base station adjusts the RIS beam based on the information reported by the UE to realize interference coordination. Specifically, the base station can determine the phase shift matrix (i.e., beamforming) of the RIS according to the measurement information reported by the plurality of UEs, and adjust the coverage range or coverage direction of the RIS by adjusting the phase shift matrix of the RIS, thereby avoiding interference between different UEs or cells.

[0256] The related content involved in the present scheme is specifically exemplified below.

[0257] Regarding the related content that can be configured and / or predefined:

[0258] 1. The RIS measurement signal is associated with the RIS beam in a limited area (for example, one cell or two or three adjacent cells) (which can correspond to the above beam measurement signal associated with the beam in the first area), for example, the measurement signal sequence (which can be understood as the original measurement sequence, which is associated with the corresponding beam; the UE can understand that this sequence corresponds to the corresponding beam) transmitted by RIS beam 1 is "10001001", the measurement signal sequence transmitted by RIS beam 2 is "10001011", and so on.

[0259] 2. Predefined measurement time T (corresponding to the above first time period): within the measurement time T, the UE measures all RIS measurement signals received during this time period and records the corresponding measurement information.

[0260] 3、RIS measurement signal can be sent periodically, semi-periodically, or non-periodically. The sending time indication corresponding to the RIS measurement signal can be the nth slot of a frame. For example, periodicity means sending periodically on the nth slot of multiple frames.

[0261] 4、Service RIS means the RIS that provides service to the UE (forwarding the signal sent by the base station to the UE); non-service RIS means the RIS that does not provide service to the UE (forwarding the signal sent by the base station to other UEs).

[0262] 5、For a UE, one or more RISs can be selected as service RISs, and one or more RIS beams in each RIS can be selected as the service RIS beam of the UE (corresponding to the above-mentioned service beam). In some embodiments, only one RIS beam is selected as the service RIS beam of the UE. The service beam refers to the beam that provides service to the UE, and the non-service beam refers to the beam that does not provide service to the UE.

[0263] 6、The reporting rule of the measurement information corresponding to the RIS measurement signal (which can correspond to the above-mentioned reporting content determination rule) can be determined according to the base station configuration or the pre-defined rule, including the following possibilities:

[0264] (1) Select the best one or more RISs as service RISs according to the weight ordering, and report the measurement information corresponding to one or more beams in each RIS; which can correspond to the above-mentioned reporting 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 service to the terminal. Among them, the weight in the weight ordering is obtained by, for example, normalizing and superimposing the weights of multiple RIS beams under the same RIS device to obtain the weight of the RIS device; the RIS beam weight is obtained by normalizing the measurement result of each measurement information (or beam).

[0265] (2) Report the measurement information corresponding to all received measurement signals; which can correspond to the above-mentioned reporting the measurement information corresponding to all received beam measurement signals as the reporting content.

[0266] (3) Report the measurement information corresponding to the best several beam measurement signals according to the ordering (signal quality or channel state); which can correspond to the above-mentioned reporting the measurement information corresponding to the beam measurement signal at the target position in the first ordering as the reporting content; the first ordering refers to the ordering of the beam measurement signal according to the measurement information corresponding to the beam measurement signal.

[0267] The measurement information corresponding to the RIS measurement signal can include one or more of an RIS indication, an RIS beam indication, an RIS measurement signal indication, and corresponding measurement results (for example, at least one of Reference Signal Receiving Power (RSRP), Channel State Information (CSI), Pre-coding matrix Indication (PMI), Block Error Rate (BLER), and the like). If the measurement result is good, the corresponding RIS and the used regulation matrix can both be used by the network side, which can also belong to the above-mentioned "configurable and / or predefined related content". Specifically, if the measurement result is good, the UE reports the base station, and the base station will select the corresponding RIS and beam (regulation) for signal transmission according to the measurement result. Specifically, multiple or one can be selected in combination with the interference condition, which is not limited here.

[0268] In the embodiments of the present disclosure, the "RIS indication, RIS beam indication, and / or RIS measurement signal indication" can be information indicating the identity, such as an identity identifier. For example, the RIS indication is used to indicate the identity information of the RIS (device), which can be any signaling or information with the meaning of indicating the RIS, such as an RIS index. The RIS beam indication is used to indicate the identity information of the RIS beam, but it is not limited to this.

[0269] The measurement signal sequence can be determined and distinguished in combination with the RIS indication + RIS beam indication (the corresponding beam can be distinguished in combination with the RIS indication + RIS beam indication), or the measurement signal sequence can be determined and distinguished in combination with the RIS beam indication (the corresponding can be all RIS beams numbered together for beam distinction), which is not limited here.

[0270] 7. The timing of the UE reporting the measurement information (corresponding to the above reporting timing) can be configured by the base station or determined according to the predefinition, for example, the UE reports in the next subframe after the end of the pre-defined measurement time T.

[0271] 6 and 7 in the above "configurable and / or predefined related content" can correspond to the reporting parameters indicated according to the first configuration information, to determine the reporting timing of sending the target measurement information to the second network device, and / or to determine the target measurement information; wherein the first configuration information is pre-defined 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.

[0272] Regarding the specific process:

[0273] I. RIS side:

[0274] 1. The RIS sends a measurement signal according to the base station configuration or predefined rule (may correspond to the above-mentioned sending of at least one beam measurement signal; the beam measurement signal is associated with the beam in the first area), and the behavior of sending the measurement signal can be:

[0275] (1) The RIS forwards the base station signal while modulating the signal, adds the measurement signal (for example, uniformly adds a certain phase) and sends it to the UE.

[0276] (2) The RIS itself has a simple signal transmission function, for example, a reconfigurable distributed antenna and reflecting surface (Reconfigurable Distributed Antennas and Reflecting Surface, RDARS), RSARS can switch the switch connected to the remote radio unit (Remote Radio Unit, RRU) through the control circuit. When connected to the RRU, it has a signal transmission function.

[0277] (3) Each RIS is equipped with a controller, and the controller sends a measurement signal through the RIS forwarding, and the controller is very close to the RIS panel.

[0278] 2. The RIS adjusts the phase shift matrix according to the base station configuration or predefined rule and forwards the signal sent by the base station.

[0279] II. UE side:

[0280] Step 0: (In some embodiments) UE receives base station configuration information or notification information. For example: in the scenario of determining to switch the RIS by the base station according to the measurement information reported by the UE, the base station can notify the UE of the candidate RIS; subsequently, the UE can measure the candidate RIS after receiving the base station notification, and obtain the channel information of the candidate RIS.

[0281] Step 1: The UE receives the RIS measurement signal according to the base station configuration or predefined rule at the RIS measurement signal receiving opportunity in the measurement time T to perform measurement (may correspond to the above-mentioned measurement of at least two beam measurement signals sent by at least two first network devices), and stores the measurement information. Wherein, the measurement behavior can include the following two kinds:

[0282] 1) In the case where the UE does not determine the service RIS, measure all received RIS measurement signals to obtain channel information (for example, at least one of RSRP, azimuth of arrival (Azimuth of Arrival, AOA), zenith angle of arrival (Zenith angle Of Arrival, ZOA), rank indicator (Rank Indicator, RI), CSI, etc. Information).

[0283] 2) In the case that the UE determines the serving RIS, the UE measures at least one of the following:

[0284] a) Measure the measurement signal of the serving RIS to obtain the 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 the interference information (e.g., at least one of power, power ratio with the serving RIS measurement signal, RSRP, etc.).

[0285] b) Measure the measurement signal of the candidate (serving) RIS to obtain the channel information of the candidate RIS, and measure the measurement signal of the non-candidate (serving) RIS to obtain the interference information (corresponding to the non-candidate RIS).

[0286] Step 2: The UE reports the measured measurement information (which can correspond to the target measurement information in the above-mentioned sending of the measurement information to the second network device) according to the base station configuration or pre-defined rule, and for the two cases shown in Step 1, the information reported by the UE can include the following two possibilities:

[0287] 1) The UE selects the measurement information of one or more beams of multiple RISs from all the received RIS measurement signals according to the base station configuration or pre-defined rule and reports it to the base station (i.e., reports the measurement information of one or more beams of multiple RISs, which can 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, etc.)), and one example is shown in Table 1 below.

[0288] Table 1

[0289] Wherein the measurement signal corresponds to the RIS beam one by one, and the UE determines the measured RIS (device) or RIS beam according to the received measurement signal. One method of correspondence between measurement signal, RIS and RIS beam is as follows:

[0290] The RIS indication and RIS beam indication are included in the measurement signal, for example, RIS1 BF1 (i.e., beam 1 of RIS device 1) is indicated as "0000", i.e., 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.

[0291] The UE can obtain the RIS and RIS beam indication according to the solved measurement signal.

[0292] 2) UE reports channel information (e.g., at least one of RSRP, AOA, ZOA, RI, CSI, etc.) of the serving RIS and interference information (e.g., at least one of power, power ratio with respect to the power of the serving RIS measurement signal, RSRP, etc.) of the non-serving RIS to the UE according to the base station configuration or a predefined rule;

[0293] In some embodiments, the predefined condition (corresponding to the first measurement index condition) can include at least one of the following:

[0294] In some embodiments, the predefined condition (corresponding to the first measurement index condition) can include at least one of the following:

[0295] 1) RSRP is greater than a certain predefined threshold; it can be understood that, according to the specific implementation, RSRP is greater than a certain threshold, which can be configured by the base station; the UE determines whether the condition is met according to the measurement result.

[0296] 2) CSI meets the target UE requirement, which can be a certain threshold associated with the requirement configured by the base station; the requirement can be determined by the UE itself or configured by the network; the target requirement can be determined according to the service requirement and the UE capability; the CSI can be reflected by PMI or RI. Among them, the target UE is the UE performing the measurement; regarding "CSI meets the target UE requirement", for example: if the CSI feedback is RI, and the specific requirement of the UE is to transmit 2 streams, then the CSI feedback RI greater than or equal to 2 can be considered to meet the requirement, but it is not limited thereto.

[0297] Step3: (In some embodiments) the UE receives a notification issued by the base station. For example, the base station indicates a service beam or switches a service beam (which can correspond to the above-mentioned reception of the first notification sent by the second network device according to the target measurement information; the first notification is used to indicate a service beam or to indicate a replacement service beam); or, the base station notifies the candidate beams that need to be further measured to assist the base station in determining the final service beam; which can correspond to the above-mentioned reception of the second notification sent by the second network device, the second notification is used to indicate the candidate service beam; according to the second notification, at least two beam measurement signals sent by at least two first network devices are measured to obtain measurement information; the at least two beam measurement signals are the beam measurement signals corresponding to the candidate service beam.

[0298] III. Base station side:

[0299] Step0 (In some embodiments): The base station configures the RIS and the UE with the RIS measurement signal transmission mode (periodic or aperiodic, etc.), transmission timing, etc. (such as configuring the UE with the reception timing), and the base station can also configure the UE with the reporting measurement information rules (such as reporting timing, format, etc.).

[0300] Of course, this Step0 can also not be performed in this scheme, and the RIS and the UE operate according to the pre-defined rules, which are not limited here.

[0301] Step1: The base station receives the measurement information reported by the UE, which has the following two operations:

[0302] 1) For the case where the UE has not determined the service RIS, the measurement information reported by the UE is the measurement information selected by the UE from all RIS measurement signals received according to the pre-defined rules or base station configuration, which satisfies the pre-defined conditions (may include one or more of RIS indication, RIS beam indication, RIS measurement signal indication and corresponding measurement results (such as at least one of RSRP, CSI, PMI, BLEE, etc. Information)), according to which the service RIS and the service RIS beam of the UE are determined according to the pre-defined rules; which can correspond to the above-mentioned reception of the target measurement information sent by at least one terminal; according to the target measurement information, the service beam of the terminal is determined.

[0303] a) One possible service RIS selection method, including: according to the information reported by the UE, the measurement results of different beams under the same RIS are classified, and the RIS index is taken as the mark. The measurement information reported by different UEs is classified by RIS device, and the RIS index is taken as the mark, that is, the different UEs covered by the same RIS device are classified. The measurement information reported by the same UE is marked by UE, and the weight of the RIS beam corresponding to the different measurement signals under the same UE is calculated according to the measurement information (which can correspond to the case where the target measurement information sent by the terminal includes at least one channel information corresponding to the beam measurement signal, and the first weight of the first beam corresponding to the beam measurement signal corresponding to the terminal is obtained according to the target measurement information). The RIS beam is associated with the measurement signal, the weight of the RIS beam with good measurement result is high, and the weight of the RIS beam with poor measurement result is low.

[0304] For a certain UE, the weights of multiple RIS beams under the same RIS device are normalized and superimposed to obtain the weight of the RIS device; which can correspond to the above-mentioned sum of the first weights of the first beams belonging to the target network device 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. Wherein, the beam weight can be directly represented by the measurement result, and the "weight normalization superposition" can be: the weight of the RIS device corresponding to the UE is directly obtained by normalizing the sum of the beam weights corresponding to each RIS device; in addition, the normalization calculation can also be directly performed when the beam weight is calculated, and then the weight of the RIS device is directly obtained by adding the beam weights; it can be understood that the weight normalization operation in the present disclosure can be performed before (when the beam weight is obtained) or after (when the device weight is obtained), which is not limited here.

[0305] Then, the RIS device with the maximum weight can be selected as the service RIS device according to the RIS device weight; after selecting the service RIS device, the service RIS beam of the RIS under the service RIS device is selected; which can correspond to the above-mentioned selection of the service device of the terminal from the target network device according to the second weight; according to the second weight corresponding to the service device and the first weight of the corresponding first beam, the service beam of the terminal is selected from the first beam under the service device. Wherein, the specific selection process can adopt at least one of the following:

[0306] i. Multiple UEs under the same serving RIS device are ranked according to the RIS device weight, and the priority of the UE corresponding to the RIS device weight is high, and the priority of the UE corresponding to the RIS device weight is low. The UE with high priority selects the beam first, selects the beam with the largest weight as the service beam, and then removes the beam from the beam pool (corresponding to the RIS device). The next priority UE continues to select the beam with the largest weight in the beam pool, and the selected beam is removed from the beam pool. Continue to select the next UE until all UEs are selected or the beam pool is empty. The process can correspond to the above-mentioned at least one terminal with the same first network device as the service device, ranking the terminals according to the second weight corresponding to the terminal, obtaining the ranking result; according to the ranking result and the first weight of the first beam corresponding to the terminal under the service device, the selection of the service beam of the terminal is performed; wherein the first beam serves as a service beam for each terminal (i.e. each beam serves one UE).

[0307] ii. Multiple UEs under the same serving RIS device are ranked according to the RIS device weight, and the priority of the UE corresponding to the RIS device weight is high, and the priority of the UE corresponding to the RIS device weight is low. Predefine UE selection count, each beam has a count, one UE selects the beam, and the count is 1, two UEs select the beam, and the count is 2, and so on. The UE selection count of all beams is initially 0. The UE with high priority selects the beam first, selects the beam with the largest weight as the service beam, and then the beam UE selection count + 1, when the beam UE selection count is equal to N, the beam is removed from the beam pool; the next priority UE continues to select the beam with the largest weight in the beam pool, and the UE selection count of the selected beam + 1, when the beam UE selection count is equal to N, the beam is removed from the beam pool; continue to select the next UE until all UEs are selected or the beam pool is empty. The process can correspond to the above-mentioned at least one terminal with the same first network device as the service device, ranking the terminals according to the second weight corresponding to the terminal, obtaining the ranking result; according to the ranking result and the first weight of the first beam corresponding to the terminal under the service device, the selection of the service beam of the terminal is performed; wherein the first beam serves as a service beam for at least two terminals (i.e. each beam serves N UEs).

[0308] 2) The UE determines the service RIS, receives the measurement information reported by the UE, which is the channel information of the UE service RIS and the interference information of the non-service RIS, and generates the following two cases according to the information:

[0309] a) The service RIS channel information meets the signal transmission requirements of the target UE, adjusts the phase shift matrix of the non-service RIS according to the interference information of the non-service RIS, and reduces the interference of the non-service RIS to the target UE. Specifically, the following mode i (excluding interference, selecting a service beam from a service device) can be used; in addition, mode ii (not excluding interference, directly combining the interference of each UE to select a service from all beams; for example, beam 1 and interference beam 2 under the service RIS device of UE1 are both interference beams of UE2, but the signal quality of beam 1 and beam 2 is similar for UE1, and the interference of beam 1 to UE2 is greater than that of beam 2. 2, then select beam 2 as the service beam of UE1, but not limited thereto.

[0310] i. According to the measurement information (containing the interference information), the interference factors (corresponding to the first interference factor described above) of the RIS beams corresponding to different measurement signals of the same UE are calculated, the measurement signal is associated with the RIS beam, and the interference factor of the RIS beam with strong interference obtained by measurement is large, and the interference factor of the RIS beam with weak interference obtained by measurement is small (specifically, it can be similar to the calculation of the above beam weight); for a certain UE, remove one or more beams that meet the pre-defined condition (such as meeting a certain threshold or the largest interference factor) from the beam pool of the RIS, and calculate the interference factors of all UEs in the region (i.e. the measurement signal is only associated with the region, corresponding to the first region described above) in turn. Remove the beams in the beam pool of each RIS whose interference factor meets the threshold; this part of the operation can correspond to the above-mentioned according to the interference information, obtaining the first interference factor of the second beam corresponding to the beam measurement signal corresponding to the terminal; the second beam is a beam under the non-service 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 the non-service 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 the non-service device, including: according to the first interference factor greater than the second threshold in the first interference factor corresponding to all terminals in the first region, remove at least one beam in the beam pool of the first network device as the non-service device.

[0311] When the beam pool of a certain (RIS device) beam is emptied, the RIS is turned off (such as entering a closed state, an absorbing state or a diffuse scattering state); it can correspond to the above-mentioned in the case where all beams corresponding to the first network device are removed from the beam pool, then 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 closed state, an absorbing state or a diffuse scattering state.

[0312] In this mode, the RIS beam weight can also be calculated according to the measurement information (containing channel information) of the service RIS reported by the UE, and the beam with the maximum weight is selected as the service beam in the beam pool of the service RIS; the third weight of the beam in the beam pool of the service device can be obtained according to the channel information; and the service beam of the terminal is selected in the beam pool of the service device according to the third weight.

[0313] ii. According to the measurement information (including the interference information), the interference factors (corresponding to the above interference weight) of the RIS beams corresponding to different measurement signals of the same UE are calculated, the measurement signal is associated with the RIS beam, the RIS beam with strong interference obtained by measurement has a large interference factor, and the RIS beam with weak interference obtained by measurement has a small interference factor. For a certain UE, each RIS beam has an interference factor and a service weight, and the beam that meets the predefined rule (for example, the beam that meets the service weight threshold under the minimum interference factor, or the beam that meets the service weight maximum under the interference factor threshold) is selected as the service beam of the UE. This mode can correspond to the above-mentioned determination of the service weight and the interference weight corresponding to at least one third beam according to the channel information and the interference information; the third beam is the beam corresponding to the channel information or the 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; the service beam of the terminal is determined according to the service weight and the interference weight. The service weight can be obtained by referring to the RIS beam weight in 1); for example, the RIS beam with good measurement result has a high weight, and the RIS beam with poor measurement result has a low weight, but it is not limited thereto. This mode can avoid selecting a beam that cannot meet the demand as a service beam from the service device.

[0314] For example of this mode ii, assume that: beam 1 corresponds to a service weight 1 if it is a service beam for UE1, and corresponds to an interference factor 1 if it is an interference beam; beam 1 corresponds to a service weight 2 if it is a service beam for UE2, and corresponds to an interference factor 2 if it is an interference beam; when selecting the service beam of UE1, the service weight 1 and the interference factor 2 are considered for selection; when selecting the service beam of UE2, the service weight 2 and the interference factor 1 are considered for selection, but it is not limited thereto.

[0315] b) The service RIS channel information does not meet the signal transmission requirements for providing services for the target UE, and the candidate service RIS beam is selected in combination with the interference information of the non-service RIS (which can correspond to the above-mentioned execution of the first operation to obtain the candidate service beam). For example:

[0316] i. For the serving RIS device, select the RIS beam satisfying the predefined condition (e.g. all beams of the RIS, the current serving RIS beam, one or more RIS beams adjacent to the current serving RIS beam, etc.) as the candidate serving RIS beam; which can correspond to the above-mentioned for the serving device, select the beam satisfying the second condition as the candidate serving beam; the second condition includes: belonging to the serving device, and / or, adjacent to the current serving beam.

[0317] ii. For the non-serving RIS device, select one or more RIS beams with an interference factor greater than a certain threshold as candidate RIS beams; which can correspond to the above-mentioned for the non-serving device, select the fourth beam corresponding to the second interference factor greater than the first threshold as the candidate serving beam; the fourth beam is the beam under the non-serving device, and the second interference factor is the interference factor corresponding to the fourth beam indicated by the interference information.

[0318] Step 2: The base station sends configuration signaling to inform the UE of the selected serving RIS (for 1)) or candidate RIS (for 2) b)); which can correspond to the above-mentioned sending the first notification to the terminal, the first notification being used to indicate the serving beam, or to indicate the change of the serving beam; or, sending the second notification to the terminal, the second notification being used to indicate the candidate serving beam.

[0319] From the above, the present scheme can solve the interference problem between multiple users in the RIS-based MU-MIMO system; specifically, by configuring the measurement signal, it can support adjusting the beamforming according to the measurement information reported by the UE, so as to improve the system performance and reduce the interference conflict.

[0320] The present disclosure further provides a beamforming determination device for a terminal, as shown in FIG. 6, which includes a memory 61, a transceiver 62, and a processor 63:

[0321] The memory 61 is used to store computer programs; the transceiver 62 is used to transceive data under the control of the processor 63; the processor 63 is used to read the computer programs in the memory 61 and perform the following operations:
