[0152] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0153] The following is an introduction to the relevant technologies involved in this application:

[0154] 1. Signal transmission based on reflective RIS

[0155] In the downlink direction, reflective RIS can control the amplitude, phase, and polarization of the incident signal from the base station at each RIS unit to maximize the signal power of the incident signal in the desired reflection direction, thereby achieving beam steering of the incident signal from the base station. The beam-steering incident signal realizes downlink signal transmission between the base station and the terminal or user equipment (UE).

[0156] In the uplink direction, the reflective RIS can control the amplitude, phase and polarization of the incident signal from the UE in each RIS unit to maximize the signal power of the incident signal in the desired reflection direction, thereby achieving beam steering of the incident signal from the UE. The incident signal after beam steering realizes uplink signal transmission between the UE and the base station, such as Figure 1 shown.

[0157] 2.RIS structure

[0158] RIS consists of numerous passive subwavelength scattering elements with PIN junctions distributed across their surfaces. By controlling the on / off state of these PIN junctions, the amplitude and phase of the signal can be manipulated. By controlling the state of individual scattering elements (e.g., amplitude and / or phase), the wireless environment can be reconfigured, improving system performance.

[0159] Typically, RIS supports multiple RIS modes or codebooks (for example, different RIS modes or codebooks correspond to at least one of the following: the vertical elevation angle of the signal incident direction, the horizontal azimuth angle of the signal incident direction, the vertical elevation angle of the signal reflection direction, and the horizontal azimuth angle of the signal reflection direction). Due to the large number of RIS units and narrow beams in a RIS, incident beams from different directions may reflect in different directions after passing through the RIS when the RIS is in a given RIS mode. Therefore, in wireless communications, it is necessary to consider controlling the RIS mode. For example, the base station (gNB) can control the RIS mode through wired or wireless communication. However, there is currently no solution for how the base station specifically controls the RIS mode or codebook. For example, how does the base station specifically learn all supported RIS modes or codebooks and how does it activate the corresponding RIS mode or codebook?

[0160] The present invention provides an information processing method, apparatus, base station, and reconfigurable intelligent surface (RIS) controller to address the currently unresolved issue of how the base station controls the RIS mode or codebook on the RIS side. The method and apparatus (or base station or RIS controller) are based on the same patent application. Since the principles underlying the problems solved by the method and apparatus (or base station or RIS controller) are similar, their implementations can be referenced to each other, and any repetitions will not be repeated.

[0161] like Figure 2 As shown, the embodiment of the present application provides an information processing method, comprising the following steps:

[0162] Step 21: The base station receives first information sent by the RIS controller; wherein the first information is used to indicate the number of first objects supported by RIS, and the first object includes a RIS mode or a RIS codebook.

[0163] Optionally, the RIS controller may use a fixed format, such as a bitmap, encoding, or other method, to notify the base station of the RIS modes or RIS codebooks supported by the RIS, thereby enabling the base station to control the RIS. For example, the RIS controller may send first information to the base station indicating the number of first objects supported by the RIS. Specifically, the first information may indicate the number of RIS modes supported by the RIS, or the number of RIS codebooks supported by the RIS. The base station may then determine the RIS mode index or the RIS codebook index supported by the RIS based on the first information to indicate the RIS mode or codebook to be activated by the RIS controller, thereby enabling the base station to control the RIS.

[0164] For example, the RIS controller notifies the base station that the number of RIS modes or codebooks supported by the RIS is N (N is a positive integer). The base station and the RIS controller can determine the index of the RIS mode or codebook supported by the RIS based on preset rules or rules agreed upon in the protocol.

[0165] Step 22: The base station sends a first signaling to the RIS controller according to the first information; wherein the first signaling carries information related to the activated first object.

[0166] Optionally, the first signaling may be existing communication signaling between the base station and the RIS controller, that is, the existing signaling between the base station and the RIS controller carries information related to the activated first object. Alternatively, the first signaling may be newly added communication signaling between the base station and the RIS controller, etc., although this embodiment of the present application is not limited thereto.

[0167] Optionally, the information related to the activated first object carried or borne by the first signaling is used to instruct the RIS controller to perform processing related to the activated first object.

[0168] For example, the base station and the RIS controller may determine the index of the RIS mode or codebook supported by the RIS based on a preset rule or a rule agreed upon in a protocol and according to the number of RIS modes or codebooks supported by the RIS, so that the base station may control the RIS controller to activate the corresponding RIS mode or codebook based on the index of the RIS mode or codebook supported by the RIS.

[0169] In the above solution, the base station receives first information sent by the RIS controller, where the first information is used to indicate the number of first objects (i.e., RIS modes or RIS codebooks) supported by the RIS. That is, when the base station learns the number of RIS modes or RIS codebooks supported by the RIS, it can send first signaling to the RIS controller carrying information related to the activated first objects to instruct the RIS controller to perform processing related to the activated first objects, thereby enabling the base station to control the RIS mode or RIS codebook, and solving the current problem of how the base station side controls the RIS mode or codebook on the RIS side, which currently has no solution.

[0170] Optionally, the first information includes at least one of the following:

[0171] The number of first objects in the vertical dimension in the signal incident direction supported by RIS; for example, the number of RIS patterns in the vertical dimension in the signal incident direction supported by RIS, or the number of RIS codebooks in the vertical dimension in the signal incident direction supported by RIS.

[0172] The number of first objects in the horizontal dimension in the signal incident direction supported by RIS; for example, the number of RIS modes in the horizontal dimension in the signal incident direction supported by RIS, or the number of RIS codebooks in the horizontal dimension in the signal incident direction supported by RIS.

[0173] The number of first objects in the vertical dimension in the signal reflection direction supported by RIS; for example, the number of RIS patterns in the vertical dimension in the signal reflection direction supported by RIS, or the number of RIS codebooks in the vertical dimension in the signal reflection direction supported by RIS.

[0174] The number of first objects in the horizontal dimension in the signal reflection direction supported by RIS; for example, the number of RIS patterns in the horizontal dimension in the signal reflection direction supported by RIS, or the number of RIS codebooks in the horizontal dimension in the signal reflection direction supported by RIS.

[0175] For example, the RIS controller may use wireless communication or wired communication to report to the base station at least one of the number of first objects in the vertical dimension in the signal incident direction supported by the RIS (I1), the number of first objects in the horizontal dimension in the signal incident direction supported by the RIS (I2), the number of first objects in the vertical dimension in the signal reflection direction supported by the RIS (I3), and the number of first objects in the horizontal dimension in the signal reflection direction supported by the RIS (I4).

[0176] Taking the vertical dimension in the direction of signal incidence as an example, the number of RIS patterns or codebooks is illustrated: for example, the angle range of the vertical dimension in the direction of signal incidence is 0 to 180°, and the preset rule is to use 1° as the step size. Then, the number of RIS patterns or codebooks in the vertical dimension in the direction of signal incidence is 181, and the corresponding vertical angles in the direction of signal incidence are 0, 1°, 2°, ... 180°, in sequence. It should be noted that this embodiment is only an illustrative example of the number of RIS patterns or codebooks, and the specific rules of the embodiments of this application are not limited to this.

[0177] For example, if the first information includes I1, the number of RIS modes or codebooks supported by the corresponding RIS is I1. Similarly, if the first information includes I2, the number of RIS modes or codebooks supported by the corresponding RIS is I2, and so on. If the first information includes I1 and I2, the number of RIS modes or codebooks supported by the corresponding RIS is I1*I2. Similarly, if the first information includes I2 and I3, the number of RIS modes or codebooks supported by the corresponding RIS is I2*I3, and so on. If the first information includes I1, I2, and I3, the number of RIS modes or codebooks supported by the corresponding RIS is I1*I2*I3. Similarly, if the first information includes I2, I3, and I4, the number of RIS modes or codebooks supported by the corresponding RIS is I2*I3*I4, and so on. If the first information includes I1, I2, I3, and I4, the number of RIS modes or codebooks supported by the corresponding RIS is I1*I2*I3*I4.

[0178] Optionally, the information related to the activated first object includes at least one of the following:

[0179] The index corresponding to the first activated object; for example, the index can be used to instruct the RIS controller to activate which RIS mode or modes or codebooks.

[0180] The effective time corresponding to the activated first object; for example, the effective time may be used to indicate when the RIS controller activates the corresponding RIS mode or codebook.

[0181] The validity period corresponding to the activated first object; for example, the validity period can be used to indicate the duration (or effective duration) of the RIS mode or codebook activated by the RIS controller, that is, within the validity period or duration or effective duration, the activated RIS mode or codebook remains unchanged.

[0182] Taking the first information reported by the RIS controller to the base station including I1, I2, I3 and I4 as an example, the base station generates an index range of a controllable RIS mode or codebook based on the received I1, I2, I3 and I4, such as:

[0183] The index i of the RIS pattern or codebook in the vertical dimension of the signal incident direction 1,1 ,i 1,1 =0,1,……,I1-1;

[0184] The index i of the RIS pattern or codebook in the horizontal dimension of the signal incident direction 1,2 ,i 1,2 =0,1,……,I2-1;

[0185] The index i of the RIS pattern or codebook in the vertical dimension of the signal reflection direction 2,1 ,i 2,1 =0,1,……,I3-1;

[0186] The index i of the RIS pattern or codebook in the horizontal dimension in the signal reflection direction 2,2 ,i 2,2 =0,1,……,I4-1.

[0187] For example, when the RIS controller reports I1, I2, I3, and I4 to the base station, the base station indicates the index of the activated RIS mode or codebook to the RIS controller, and the index can be obtained by i 1,1 ,i 1,2 ,i 2,1 ,i 2,1 Optionally, the base station may further configure an effective time and / or effective period for the activated RIS mode or codebook.

[0188] It should be noted that the form in which the base station indicates the index of the activated RIS mode or codebook to the RIS controller in this embodiment is only an example. For example, when the RIS controller reports I1 to the base station, the base station indicates the index of the activated RIS mode or codebook to the RIS controller, and the index can be obtained by i 1,1 For example, when the RIS controller reports I1 and I2 to the base station, the base station indicates the index of the activated RIS mode or codebook to the RIS controller, and the index can be expressed by i 1,1 ,i 1,2 To represent the like, the embodiments of the present application are not limited thereto.

[0189] Optionally, the base station may transmit at least one of an index of an activated RIS mode or codebook, an effective time of the activated RIS mode or codebook, and an effective period of the activated RIS mode or codebook to the RIS controller via wireless or wired communication. The RIS controller may then perform the following operations based on the received index of the activated RIS mode or codebook, the effective time of the activated RIS mode or codebook, and the effective period of the activated RIS mode or codebook:

[0190] Starting from the effective time, the RIS mode or codebook is adjusted to the RIS mode or codebook corresponding to the index; and during the effective period, the RIS mode or codebook remains unchanged as the RIS mode or codebook corresponding to the index.

[0191] Optionally, the RIS mode or codebook includes but is not limited to at least one of the following:

[0192] The elevation angle in the vertical dimension of the signal incident direction;

[0193] The azimuth angle of the horizontal dimension in the direction of signal incidence;

[0194] The elevation angle in the vertical dimension of the signal reflection direction;

[0195] Azimuth angle in the horizontal dimension of the signal reflection direction;

[0196] The state of each RIS unit in the RIS, for example, the state of the RIS unit includes: the amplitude (or amplitude) corresponding to the RIS unit and / or the phase corresponding to the RIS unit.

[0197] As shown in Table 1, an example of a RIS pattern or codebook is given.

[0198] Table 1

[0199]

[0200] Optionally, the first signaling includes at least one information field; wherein each of the information fields is used to indicate an index of at least one parameter corresponding to the activated first object, and the parameter includes at least one of the following:

[0201] The vertical dimension in the direction of signal incidence;

[0202] Horizontal dimension in the direction of signal incidence;

[0203] The vertical dimension in the direction of signal reflection;

[0204] The horizontal dimension in the direction of signal reflection.

[0205] For example: the first signaling may include an information field, which can be used to indicate the index of at least one parameter corresponding to the activated first object. For example, if at least one parameter includes a vertical dimension in the signal incident direction, then the information field is used to indicate the index of the vertical dimension in the signal incident direction corresponding to the activated first object. For another example: if at least one parameter includes a vertical dimension in the signal incident direction and a horizontal dimension in the signal incident direction, then the information field is used to indicate the index of the vertical dimension in the signal incident direction corresponding to the activated first object, as well as the index of the horizontal dimension in the signal incident direction, etc., which will not be repeated here.

[0206] For another example: the first signaling may include multiple information domains, each information domain can be used to indicate the index of at least one parameter corresponding to the activated first object, and different information domains can be used to indicate the indexes of different parameters corresponding to the activated first object, such as one information domain among the multiple information domains is used to indicate the index of the vertical dimension in the signal incident direction corresponding to the activated first object, another information domain among the multiple information domains is used to indicate the index of the horizontal dimension in the signal incident direction corresponding to the activated first object, and so on; for another example, one information domain among the multiple information domains is used to indicate the index of the vertical dimension in the signal incident direction and the index of the horizontal dimension in the signal incident direction corresponding to the activated first object, another information domain among the multiple information domains is used to indicate the index of the vertical dimension in the signal reflection direction corresponding to the activated first object, and so on, and no further details will be given here.

[0207] Optionally, as an implementation manner: the information field indicates the index of at least one parameter corresponding to the activated first object in the form of a bitmap.

[0208] For example, taking at least one parameter including the vertical dimension in the signal incident direction as an example, the number of first objects in the vertical dimension in the signal incident direction supported by RIS is I1, then I1 bits can be used to indicate the index of the vertical dimension in the signal incident direction corresponding to the activated first object, for example, the I1 bit sequence is "0001000...0", where the value of the 4th bit is "1" and the values ​​of other bits are "0", then the 4th bit in the I1 bit sequence indicates the index of the vertical dimension in the signal incident direction corresponding to the activated first object, for example, the index of the vertical dimension in the signal incident direction corresponding to the activated first object is determined to be "3".

[0209] For another example, taking at least one parameter including the vertical dimension in the signal incident direction and the horizontal dimension in the signal incident direction, the number of first objects in the vertical dimension in the signal incident direction supported by RIS is I1, and the number of first objects in the horizontal dimension in the signal incident direction supported by RIS is I2, then I1 bits can be used to indicate the index of the vertical dimension in the signal incident direction corresponding to the activated first object, and I2 bits can be used to indicate the index of the horizontal dimension in the signal incident direction corresponding to the activated first object. For example, the first I1 bit sequence is "0001000...0", and the last I2 bit sequence is "000001...0", that is, the value of the 4th bit in the first I1 bit sequence is "1", and the values ​​of other bits are "0", then the 4th bit in the first I1 bit sequence indicates the index of the vertical dimension in the signal incident direction corresponding to the activated first object, for example, the index of the vertical dimension in the signal incident direction corresponding to the activated first object is determined to be "3"; the value of the 6th bit in the last I2 bits is "1", and the values ​​of other bits are "0", then the 6th bit in the last I2 bits indicates the index of the horizontal dimension in the signal incident direction corresponding to the activated first object, for example, the index of the horizontal dimension in the signal incident direction corresponding to the activated first object is determined to be "5".

[0210] It should be noted that in addition to using "1" to represent the index of the activated first object and "0" to represent the index of the inactivated first object, "0" can also be used to represent the index of the activated first object and "1" can be used to represent the index of the inactivated first object, etc. The embodiments of the present application are not limited to this.

[0211] It should also be noted that, in this embodiment, the use of a bitmap to indicate the index of at least one parameter corresponding to the activated first object is merely an exemplary description, and the embodiments of the present application are not limited thereto.

[0212] Optionally, as another implementation manner: the information field uses X bits to indicate the index of at least one parameter corresponding to the activated first object; wherein X is determined by the number of first objects corresponding to the at least one parameter supported by RIS, and X is a positive integer.

[0213] For example, X can be determined by the following formula:

[0214]

[0215] Here, I represents the number of first objects corresponding to at least one parameter supported by RIS.

[0216] For example, taking at least one parameter including the vertical dimension in the signal incident direction as an example, the number of first objects in the vertical dimension in the signal incident direction supported by RIS is I1, then bits indicate the index of the vertical dimension in the signal incident direction corresponding to the first activated object, and the bit sequence is represented by a 0, a 1, ……,a X-2 ,a X-1 For example, if the X bit sequence is "00...00", it means that the index of the vertical dimension in the signal incident direction corresponding to the first activated object is 0, and so on.

[0217] For another example, taking at least one parameter including the vertical dimension in the signal incident direction and the horizontal dimension in the signal incident direction as an example, the number of first objects in the vertical dimension in the signal incident direction supported by RIS is I1, and the number of first objects in the horizontal dimension in the signal incident direction supported by RIS is I2, then the above method can be used. bits indicate the index of the vertical dimension in the signal incident direction corresponding to the first activated object, and the following bits indicate the index of the horizontal dimension in the signal incident direction corresponding to the first activated object; the first X1 bit sequence is The next X2 bit sequence is For example, if the first X1 bit sequences are "00...00" and the last X2 bit sequences are "00...01", it means that the index of the vertical dimension in the signal incident direction corresponding to the activated first object is 0, and the index of the horizontal dimension in the signal incident direction corresponding to the activated first object is 1, and so on.

[0218] It should also be noted that, in this embodiment, using X bits (ie, using an encoding method) to indicate the index of at least one parameter corresponding to the activated first object is only an exemplary description, and the embodiments of the present application are not limited thereto.

[0219] Optionally, as an implementation method: when the at least one information field includes a first information field, the first information field is used to indicate the index of the vertical dimension in the signal incident direction, the index of the horizontal dimension in the signal incident direction, the index of the vertical dimension in the signal reflection direction, and the index of the horizontal dimension in the signal reflection direction corresponding to the activated first object.

[0220] In this embodiment, one information field X1 is used to indicate the mixed index i1, i.e., i1=(i 1,1 ,i 1,2 ,i 2,1 ,i 2,2 ) represents the index i of the vertical dimension in the signal incident direction corresponding to the first activated object 1,1 , the index i of the horizontal dimension in the direction of signal incidence 1,2 , index i of the vertical dimension in the direction of signal reflection 2,1and the index i of the horizontal dimension in the direction of signal reflection 2,2 .

[0221] For example, the information field X1 is in a bitmap format to indicate the mixed index i1. The bit width of the information field X1 is shown in Table 2.

[0222] Table 2

[0223]

[0224] For example, when the base station uses the bitmap method to indicate the mixed index i1 through the information field X1, specifically:

[0225] In the first I1 bit sequence in the information domain X1, the i-th 1,1 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the vertical dimension in the signal incident direction corresponding to the first activated object according to the position of the bit with the value "1" in the first I1 bit sequence in the information field X1. 1,1 ;

[0226] In the bit sequence from I1 to (I1+I2-1) in the information domain X1, the i-th 1,2 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the horizontal dimension in the signal incident direction corresponding to the first activated object according to the position of the bit with the value "1" in the bit sequence from I1 to (I1+I2-1) in the information field X1. 1,2 ;

[0227] In the bit sequence from (I1+I2) to (I1+I2+I3-1) in the information domain X1, the i-th 2,1 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the vertical dimension in the signal reflection direction corresponding to the activated first object according to the position of the bit with the value "1" in the bit sequence from (I1+I2) to (I1+I2+I3-1) in the information field X1. 2,1 ;

[0228] In the information domain X1, in the bit sequences from (I1+I2+I3) to (I1+I2+I3+I4-1) (i.e., the last I4 bit sequences), the i-th bit sequence 2,2 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the horizontal dimension index i in the signal reflection direction corresponding to the activated first object according to the position of the bit with the value "1" in the last I4 bit sequence in the information field X1.2,2 .

[0229] For another example, the information field X1 is encoded to indicate the mixed index i1. The bit width of the information field X1 is shown in Table 3.

[0230] Table 3

[0231]

[0232] For example, when the base station indicates the mixed index i1 through the information field X1 in a coding manner, specifically:

[0233] In the information field X1 bits, using the previous A bit sequence represents the value "i 1,1 "; then the RIS controller can The bit sequence is decoded to obtain the index i of the vertical dimension in the signal incident direction corresponding to the first activated object 1,1 ;

[0234] In the information domain X1 arrive bits, using the arrive A bit sequence represents the value "i 1,2 "; then the RIS controller can arrive The bit sequence is decoded to obtain the index i of the horizontal dimension in the signal incident direction corresponding to the first activated object 1,2 ;

[0235] In the information domain X1 arrive bits, using the arrive A bit sequence represents the value "i 2,1 "; then the RIS controller can arrive The bit sequence is decoded to obtain the index i of the vertical dimension in the signal reflection direction corresponding to the first activated object 2,1 ;

[0236] In the information domain X1 arrive bits (that is, the latter bits), the following A bit sequence represents the value "i 2,2"; then the RIS controller can The bit sequence is decoded to obtain the index i of the horizontal dimension in the signal reflection direction corresponding to the first activated object 2,2 .

[0237] Optionally, as another implementation method: when the at least one information domain includes a first information domain and a second information domain, the first information domain is used to indicate the index of the vertical dimension in the signal incident direction corresponding to the activated first object and the index of the horizontal dimension in the signal incident direction, and the second information domain is used to indicate the index of the vertical dimension in the signal reflection direction corresponding to the activated first object and the index of the horizontal dimension in the signal reflection direction.

[0238] In this embodiment, two information fields X1 and X2 are used to indicate the mixed indexes i1 and i2 respectively. For example, the information field X1 is used to indicate the mixed index i1, and i1=(i 1,1 ,i 1,2 ) represents the index i of the vertical dimension in the signal incident direction corresponding to the first activated object 1,1 and the index i of the horizontal dimension in the direction of signal incidence 1,2 ; The information field X2 is used to indicate the mixed index i2, and i2 = (i 2,1 ,i 2,2 ) represents the index i of the vertical dimension in the signal reflection direction corresponding to the first activated object 2,1 and the index i of the horizontal dimension in the direction of signal reflection 2,2 .

[0239] For example, information fields X1 and X2 are both in bitmap format, indicating mixed indexes i1 and i2 respectively. The bit widths of information fields X1 and X2 are shown in Table 4.

[0240] Table 4

[0241]

[0242] For example, when the base station uses the bitmap method to indicate the mixed index i1 through the information field X1, specifically:

[0243] In the first I1 bit sequence in the information domain X1, the i-th 1,1 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the vertical dimension in the signal incident direction corresponding to the first activated object according to the position of the bit with the value "1" in the first I1 bit sequence in the information field X1. 1,1 ;

[0244] In the last I2 bit sequence in the information field X1, the i-th 1,2bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the horizontal dimension in the signal incident direction corresponding to the activated first object according to the position of the bit with the value "1" in the last I2 bit sequence in the information field X1. 1,2 .

[0245] Similarly, when the base station indicates the mixed index i2 through the information field X2 in a bitmap manner:

[0246] In the first I3 bit sequence in the information field X2, the i-th 2,1 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the vertical dimension in the signal reflection direction corresponding to the activated first object according to the position of the bit with the value "1" in the first I3 bit sequence in the information field X2 2,1 ;

[0247] In the last 14 bits of the information field X2, the i-th 2,2 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the horizontal dimension index i in the signal reflection direction corresponding to the activated first object according to the position of the bit with the value "1" in the last I4 bit sequence in the information field X2. 2,2 .

[0248] For another example, information fields X1 and X2 are both encoded to indicate mixed indexes i1 and i2. The bit widths of information fields X1 and X2 are shown in Table 5.

[0249] Table 5

[0250]

[0251] For example, when the base station indicates the mixed index i1 through the information field X1 in a coding manner, specifically:

[0252] In the information field X1 bits, using the previous A bit sequence represents the value "i 1,1 "; then the RIS controller can The bit sequence is decoded to obtain the index i of the vertical dimension in the signal incident direction corresponding to the first activated object 1,1 ;

[0253] In the information field X1 bits, using the A bit sequence represents the value "i 1,2 "; then the RIS controller can The bit sequence is decoded to obtain the index i of the horizontal dimension in the signal incident direction corresponding to the first activated object 1,2 ;

[0254] Similarly, when the base station indicates the mixed index i2 through the information field X2 in an encoding manner:

[0255] Before in information domain X2 bits, using the previous A bit sequence represents the value "i 2,1 "; then the RIS controller can The bit sequence is decoded to obtain the index i of the vertical dimension in the signal reflection direction corresponding to the first activated object 2,1 ;

[0256] In the information field X2 bits, using the A bit sequence represents the value "i 2,2 "; then the RIS controller can The bit sequence is decoded to obtain the index i of the horizontal dimension in the signal reflection direction corresponding to the first activated object 2,2 .

[0257] Optionally, as another implementation method: when the at least one information domain includes a first information domain, a second information domain, a third information domain and a fourth information domain, the first information domain is used to indicate the index of the vertical dimension in the signal incident direction corresponding to the activated first object, the second information domain is used to indicate the index of the horizontal dimension in the signal incident direction corresponding to the activated first object, the third information domain is used to indicate the index of the vertical dimension in the signal reflection direction corresponding to the activated first object, and the fourth information domain is used to indicate the index of the horizontal dimension in the signal reflection direction corresponding to the activated first object.

[0258] In this embodiment, four information fields X1, X2, X3 and X4 are used to indicate the index i 1,1 、i 1,2 、i 2,1 and i 2,2 For example, the information field X1 is used to indicate the index i of the vertical dimension in the signal incident direction corresponding to the activated first object. 1,1 The information field X2 is used to indicate the index i of the horizontal dimension in the signal incident direction corresponding to the activated first object. 1,2 The information field X3 is used to indicate the index i of the vertical dimension in the signal reflection direction corresponding to the activated first object. 2,1 The information field X4 is used to indicate the index i of the horizontal dimension in the signal reflection direction corresponding to the activated first object. 2,2 .

[0259] For example, the information fields X1, X2, X3 and X4 are all in the form of bitmaps, indicating the index i 1,1 、i 1,2 、i 2,1 and i 2,2 The bit widths of the information fields X1, X2, X3, and X4 are shown in Table 6.

[0260] Table 6

[0261]

[0262] For example, the base station uses bitmap to indicate index i through X1, X2, X3 and X4 respectively. 1,1 、i 1,2 、i 2,1 and i 2,2 When, specifically:

[0263] In the I1 bit sequence in the information field X1, the i-th 1,1 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the vertical dimension in the signal incident direction corresponding to the activated first object according to the position of the bit with the value "1" in the bit sequence of the information field X1. 1,1 ;

[0264] In the I2 bit sequence in the information field X2, the i-th 1,2 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the horizontal dimension in the signal incident direction corresponding to the activated first object according to the position of the bit with the value "1" in the bit sequence of the information field X2. 1,2 .

[0265] In the I3 bit sequence in the information field X3, the i-th 2,1 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the vertical dimension in the signal reflection direction corresponding to the activated first object according to the position of the bit with the value "1" in the bit sequence of the information field X3. 2,1 ;

[0266] In the I4 bit sequence in the information field X4, the i-th 2,2 bits are set to "1" and the other bits are set to "0"; then the RIS controller can determine the index i of the horizontal dimension in the signal reflection direction corresponding to the activated first object according to the position of the bit with the value "1" in the bit sequence of the information field X4. 2,2 .

[0267] For another example, the information fields X1, X2, X3 and X4 are all coded to indicate index i 1,1 、i 1,2 、i 2,1 and i 2,2 The information fields X1, X2, X3 and X4 are shown in Table 7.

[0268] Table 7

[0269]

[0270] For example, the base station uses coding to indicate index i through X1, X2, X3 and X4 respectively. 1,1 、i 1,2 、i 2,1 and i 2,2 When, specifically:

[0271] In the information domain X1 bits, the bit sequence is If the bit sequence It means i 1,1 = 0, if the bit sequence It means i 1,1 =1, and so on. Then the RIS controller can decode the bit sequence of the information field X1 to obtain the index i of the vertical dimension in the signal incident direction corresponding to the activated first object. 1,1 ;

[0272] In the information domain X2 bits, the bit sequence is If the bit sequence It means i 1,2 = 0, if the bit sequence It means i 1,2 =1, and so on. Then the RIS controller can decode the bit sequence of the information field X2 to obtain the index i of the horizontal dimension in the signal incident direction corresponding to the activated first object. 1,2 ;

[0273] In the information domain X3 bits, the bit sequence is If the bit sequence It means i 2,1 = 0, if the bit sequence It means i 2,1 =1, and so on. Then the RIS controller can decode the bit sequence of the information field X3 to obtain the index i of the vertical dimension in the signal reflection direction corresponding to the activated first object. 2,1 ;

[0274] In the information domain X4 bits, the bit sequence is If the bit sequence It means i 2,2 = 0, if the bit sequence It means i 2,2 =1, and so on. Then the RIS controller can decode the bit sequence of the information field X4 to obtain the index i of the horizontal dimension in the signal reflection direction corresponding to the activated first object. 2,2 .

[0275] In this embodiment of the present application, the RIS controller reports the number of RIS modes or codebooks supported by the RIS to the base station. The base station can also indicate the index of the active RIS mode or codebook to the RIS controller via a bitmap or encoding method to implement RIS mode or codebook control. Furthermore, the base station can indicate the effective time and / or effective period of the activated RIS mode or codebook to enable the RIS controller to control the RIS mode or codebook at a specific time and within a specific period.

Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with wireless devices on the air interface through one or more sectors, or other names. The base station can be used to exchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The base station can also coordinate the attribute management of the air interface. For example, the base station involved in the embodiments of the present application can be a base station (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a base station (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which is not limited in the embodiments of the present application. In some network structures, the base station may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0277] like Figure 3 As shown, an embodiment of the present application provides an information processing method, comprising the following steps:

[0278] Step 31: The RIS controller sends first information to the base station; wherein the first information is used to indicate the number of first objects supported by RIS, and the first objects include RIS modes or RIS codebooks.

[0279] Optionally, the RIS controller may use a fixed format, such as a bitmap, encoding, or other method, to notify the base station of the RIS modes or RIS codebooks supported by the RIS, thereby enabling the base station to control the RIS. For example, the RIS controller may send first information to the base station indicating the number of first objects supported by the RIS. Specifically, the first information may indicate the number of RIS modes supported by the RIS, or the number of RIS codebooks supported by the RIS. The base station can then determine the RIS mode index or the RIS codebook index supported by the RIS based on the first information, thereby indicating the RIS mode or codebook to be activated by the RIS controller, thereby enabling the base station to control the RIS.

[0280] For example, the RIS controller notifies the base station that the number of RIS modes or codebooks supported by the RIS is N (N is a positive integer). The base station and the RIS controller can determine the index of the RIS mode or codebook supported by the RIS based on preset rules or rules agreed upon in the protocol.

[0281] Step 32: The RIS controller receives a first signaling sent by the base station; wherein the first signaling carries information related to the activated first object.

[0282] Optionally, the first signaling may be existing communication signaling between the base station and the RIS controller, that is, the existing signaling between the base station and the RIS controller carries information related to the activated first object. Alternatively, the first signaling may be newly added communication signaling between the base station and the RIS controller, etc., although this embodiment of the present application is not limited thereto.

[0283] Optionally, the information related to the activated first object carried or borne by the first signaling is used to instruct the RIS controller to perform processing related to the activated first object.

[0284] For example, the base station and the RIS controller may determine the index of the RIS mode or codebook supported by the RIS based on a preset rule or a rule agreed upon in a protocol and according to the number of RIS modes or codebooks supported by the RIS, so that the base station may control the RIS controller to activate the corresponding RIS mode or codebook based on the index of the RIS mode or codebook supported by the RIS.

[0285] Step 33: The RIS controller executes relevant processing for activating the first object corresponding to the RIS according to the relevant information of the activated first object.

[0286] In the above solution, the RIS controller sends first information to the base station, where the first information is used to indicate the number of first objects (i.e., RIS modes or RIS codebooks) supported by the RIS. That is, when the base station learns the number of RIS modes or RIS codebooks supported by the RIS, it can carry information related to the activated first objects in first signaling sent to the RIS controller. In this way, the RIS controller can perform processing related to the activated first objects based on the first signaling, thereby enabling the base station to control the RIS mode or RIS codebook. This solves the current problem of how the base station side controls the RIS mode or codebook on the RIS side, which currently has no solution.

[0287] Optionally, the first information includes at least one of the following:

[0288] The number of first objects in the vertical dimension in the signal incident direction supported by RIS; for example, the number of RIS patterns in the vertical dimension in the signal incident direction supported by RIS, or the number of RIS codebooks in the vertical dimension in the signal incident direction supported by RIS.

[0289] The number of first objects in the horizontal dimension in the signal incident direction supported by RIS; for example, the number of RIS modes in the horizontal dimension in the signal incident direction supported by RIS, or the number of RIS codebooks in the horizontal dimension in the signal incident direction supported by RIS.

[0290] The number of first objects in the vertical dimension in the signal reflection direction supported by RIS; for example, the number of RIS patterns in the vertical dimension in the signal reflection direction supported by RIS, or the number of RIS codebooks in the vertical dimension in the signal reflection direction supported by RIS.

[0291] The number of first objects in the horizontal dimension in the signal reflection direction supported by RIS; for example, the number of RIS patterns in the horizontal dimension in the signal reflection direction supported by RIS, or the number of RIS codebooks in the horizontal dimension in the signal reflection direction supported by RIS.

[0292] For example, the RIS controller may use wireless communication or wired communication to report to the base station at least one of the number of first objects in the vertical dimension in the signal incident direction supported by the RIS (I1), the number of first objects in the horizontal dimension in the signal incident direction supported by the RIS (I2), the number of first objects in the vertical dimension in the signal reflection direction supported by the RIS (I3), and the number of first objects in the horizontal dimension in the signal reflection direction supported by the RIS (I4).

[0293] Taking the vertical dimension in the direction of signal incidence as an example, the number of RIS patterns or codebooks is illustrated: for example, the angle range of the vertical dimension in the direction of signal incidence is 0 to 180°, and the preset rule is to use 1° as the step size. Then, the number of RIS patterns or codebooks in the vertical dimension in the direction of signal incidence is 181, and the corresponding vertical angles in the direction of signal incidence are 0, 1°, 2°, ... 180°, in sequence. It should be noted that this embodiment is only an illustrative example of the number of RIS patterns or codebooks, and the specific rules of the embodiments of this application are not limited to this.

[0294] For example, if the first information includes I1, the number of RIS modes or codebooks supported by the corresponding RIS is I1. Similarly, if the first information includes I2, the number of RIS modes or codebooks supported by the corresponding RIS is I2, and so on. If the first information includes I1 and I2, the number of RIS modes or codebooks supported by the corresponding RIS is I1*I2. Similarly, if the first information includes I2 and I3, the number of RIS modes or codebooks supported by the corresponding RIS is I2*I3, and so on. If the first information includes I1, I2, and I3, the number of RIS modes or codebooks supported by the corresponding RIS is I1*I2*I3. Similarly, if the first information includes I2, I3, and I4, the number of RIS modes or codebooks supported by the corresponding RIS is I2*I3*I4, and so on. If the first information includes I1, I2, I3, and I4, the number of RIS modes or codebooks supported by the corresponding RIS is I1*I2*I3*I4.

[0295] Optionally, the information related to the activated first object includes at least one of the following:

[0296] The index corresponding to the first activated object; for example, the index can be used to instruct the RIS controller to activate which RIS mode or modes or codebooks.

[0297] The effective time corresponding to the activated first object; for example, the effective time may be used to indicate when the RIS controller activates the corresponding RIS mode or codebook.

[0298] The validity period corresponding to the activated first object; for example, the validity period can be used to indicate the duration (or effective duration) of the RIS mode or codebook activated by the RIS controller, that is, within the validity period or duration or effective duration, the activated RIS mode or codebook remains unchanged.

[0299] Taking the first information reported by the RIS controller to the base station including I1, I2, I3 and I4 as an example, the base station generates an index range of a controllable RIS mode or codebook based on the received I1, I2, I3 and I4, such as:

[0300] The index i of the RIS pattern or codebook in the vertical dimension of the signal incident direction 1,1 ,i 1,1 =0,1,……,I1-1;

[0301] The index i of the RIS pattern or codebook in the horizontal dimension of the signal incident direction 1,2 ,i 1,2 =0,1,……,I2-1;

[0302] The index i of the RIS pattern or codebook in the vertical dimension of the signal reflection direction 2,1 ,i 2,1 =0,1,……,I3-1;

[0303] The index i of the RIS pattern or codebook in the horizontal dimension in the signal reflection direction 2,2 ,i 2,2 =0,1,……,I4-1.

[0304] For example, when the RIS controller reports I1, I2, I3, and I4 to the base station, the base station indicates the index of the activated RIS mode or codebook to the RIS controller, and the index can be obtained through i 1,1 ,i 1,2 ,i 2,1 ,i 2,1 Optionally, the base station may further configure an effective time and / or effective period for the activated RIS mode or codebook.

[0305] It should be noted that the form in which the base station indicates the index of the activated RIS mode or codebook to the RIS controller in this embodiment is only an example. For example, when the RIS controller reports I1 to the base station, the base station indicates the index of the activated RIS mode or codebook to the RIS controller, and the index can be obtained by i 1,1 For example, when the RIS controller reports I1 and I2 to the base station, the base station indicates the index of the activated RIS mode or codebook to the RIS controller, and the index can be expressed by i 1,1 ,i 1,2 To represent the like, the embodiments of the present application are not limited thereto.

[0306] Optionally, the RIS controller performs, based on the information related to the activated first object, a process related to activating the first object corresponding to the RIS, including at least one of the following:

[0307] The RIS controller activates the first object corresponding to the index according to the index corresponding to the activated first object;

[0308] The RIS controller activates the first object starting from the effective time according to the effective time corresponding to the activated first object;

[0309] The RIS controller keeps activating the first object within the validity period corresponding to the activated first object.

[0310] For example, when the first information includes an index corresponding to an activated first object, the RIS controller activates the first object corresponding to the index, that is, activates the RIS mode or codebook corresponding to the index.

[0311] For another example, when the first information includes an index corresponding to the activated first object and an effective time corresponding to the activated first object, the RIS controller may activate the first object corresponding to the index starting from the effective time, that is, activate the RIS mode or codebook corresponding to the index.

[0312] For another example, when the first information includes an index corresponding to an activated first object and an effective period corresponding to the activated first object, the RIS controller activates the first object corresponding to the index, that is, activates the RIS mode or codebook corresponding to the index, and maintains the activation of the RIS mode or codebook corresponding to the index unchanged during the effective period.

[0313] For another example, when the first information includes an index corresponding to the activated first object, an effective time corresponding to the activated first object, and an effective period corresponding to the activated first object, the RIS controller activates the first object corresponding to the index starting from the effective time, that is, activates the RIS mode or codebook corresponding to the index, and keeps the RIS mode or codebook corresponding to the index unchanged during the effective period.

[0314] Optionally, the RIS controller activates the first object corresponding to the index according to the index corresponding to the activated first object, including:

[0315] The RIS controller determines, based on a stored mapping relationship between an index of a first object supported by the RIS and state information of each RIS unit, first state information associated with the index corresponding to the activated first object;

[0316] The RIS controller adjusts the status of each RIS unit in the RIS according to the first status information.

[0317] For example, the state information includes an amplitude value and / or a phase value, and the state of the RIS unit refers to the amplitude and / or phase of the RIS unit.

[0318] Optionally, the RIS mode or codebook includes but is not limited to at least one of the following:

[0319] The elevation angle in the vertical dimension of the signal incident direction;

[0320] The azimuth angle of the horizontal dimension in the direction of signal incidence;

[0321] The elevation angle in the vertical dimension of the signal reflection direction;

[0322] Azimuth angle in the horizontal dimension of the signal reflection direction;

[0323] The state of each RIS unit in the RIS, for example, the state of the RIS unit includes: the amplitude (or amplitude) corresponding to the RIS unit and / or the phase corresponding to the RIS unit.

[0324] For example, RIS has at least I1*I2*I3*I4 RIS patterns or codebooks, where the i-th 1,1 ,i 1,2 ,i 2,1 ,i 2,2, The states of each RIS unit corresponding to a RIS mode or codebook can be expressed as: Among them, w n is the state of the nth RIS unit, w n ∈Ω, Ω is the state set supported by each RIS unit; N is the number of RIS units in RIS, for example: RIS consists of N v Row and N h The RIS units of the column are composed, then N=N v *N h .

[0325] If each RIS unit can achieve 1-bit control, then Ω has two states, Ω = [ξ0, ξ1], where ξ0 and ξ1 are determined by the specific RIS unit, for example: ξ0 = j, ξ1 = -j.

[0326] If each RIS unit can achieve 2-bit control, then Ω has 4 states, Ω = [ξ0, ξ1, ξ2, ξ3], where ξ0, ξ1, ξ2 and ξ3 are determined by the specific RIS unit, for example: ξ0 = 1, ξ1 = j, ξ2 = -1 and ξ3 = -j.

[0327] If each RIS unit can achieve x bit control, then Ω has Y = 2 x states, Ω=[ξ0,ξ1,……,ξ Y-1 ], where, ξ0, ξ1,...,ξ Y-1 Determined by the specific RIS unit.

[0328] Optionally, for at least one different RIS mode or codebook among the elevation angle in the vertical dimension in the signal incident direction, the azimuth angle in the horizontal dimension in the signal incident direction, the elevation angle in the vertical dimension in the signal reflection direction, and the azimuth angle in the horizontal dimension in the signal reflection direction, the state of each RIS unit in the RIS may be pre-calculated and stored in the RIS control in the following manner:

[0329] For each RIS unit in the RIS, respectively determining a power value corresponding to each state supported by the RIS unit under the activated first object;

[0330] For each RIS unit in the RIS, state information of the RIS unit is determined according to a state corresponding to a maximum power value.

[0331] Specifically, respectively determining the power value corresponding to each state supported by the RIS unit under the activated first object includes:

[0332] determining, according to a first angle value of a vertical dimension in the signal incident direction corresponding to the activated first object and a second angle value of a horizontal dimension in the signal incident direction, a unit response in the signal incident direction corresponding to each state supported by the RIS unit;

[0333] determining, according to a third angle value in a vertical dimension in the signal reflection direction corresponding to the activated first object and a fourth angle value in a horizontal dimension in the signal reflection direction, a unit response in the signal reflection direction corresponding to each state supported by the RIS unit;

[0334] determining, according to the first angle value, the second angle value, and the position information of the RIS unit in the RIS, array responses of signal incident directions corresponding to respective states supported by the RIS unit;

[0335] determining, according to the third angle value, the fourth angle value, and the position information of the RIS unit in the RIS, array responses of signal reflection directions corresponding to respective states supported by the RIS unit;

[0336] For each state corresponding to the RIS unit, a power value corresponding to the state is determined according to the unit response in the signal incident direction, the unit response in the signal reflection direction, the array response in the signal reflection direction, and the array response in the signal reflection direction.

[0337] The following describes the process of obtaining the status of each RIS unit in the RIS with reference to a specific example:

[0338] Step 1: Determine the nth RIS unit for The unit response of electromagnetic waves in the direction At the same time, determine the nth RIS unit for the Array response to electromagnetic waves in the direction

[0339] The unit response of the nth RIS unit is It can be measured by each RIS unit in the RIS, or it can be obtained by designing each RIS unit model. An example unit response Designed to:

[0341] The array response of the nth RIS unit is An example array response can be obtained from the position relationship of the nth RIS unit in the RIS. Designed to:

[0342]

[0343] in, is the position coordinate of the nth RIS unit in RIS;

[0344] It can indicate the direction of signal incidence or signal reflection; for example: In the case of the signal incident direction, θ represents the pitch angle in the vertical dimension of the signal incident direction, Indicates the azimuth angle of the horizontal dimension in the direction of signal incidence; for example: In the case of the signal reflection direction, θ represents the pitch angle in the vertical dimension of the signal reflection direction, Indicates the azimuth angle in the horizontal dimension of the signal reflection direction.

[0349] Step 1: Loop according to the RIS unit number n, that is, n = 0 to N-1;

[0350] Step 2: Cycle through the state y supported by the RIS unit numbered n, i.e., y = 0 to Y-1;

[0351] Calculate S according to the following formula state [y]:

[0352]

[0353] At this point, step 2 ends the loop of state y supported by the RIS unit with sequence number n.

[0354] Step 3: Calculate S state Medium|S state The location of the maximum value of |y state,best , if the maximum value position y is determined state,best If the number is greater than 1, take the position of the first maximum value.

[0355] Step 4: Place S state [y state,best ]Assign value to variable sig, i.e. sig=S state [y state,best ].

[0356] Step 5: Ω[y state,best ]Assign to Right now

[0357] At this point, the cycle of step 1 according to the RIS unit number is completed.

[0358] Thus, based on the above steps, the RIS pattern or codebook is obtained:

To avoid repetition, they will not be described here.

[0379]

[0380] Since the RIS units are located on the Y axis, And r n =nd, n=0,1,...,N-1, N=32, then:
