The technical basis of the intelligent super surface is an artificial material called information metamaterial, which is an artificial material having special properties and not existing in nature. They possess special properties, such as allowing light, electromagnetic waves to change their usual properties. By designing sub-wavelength artificial atoms and arranging them according to a precise geometric structure, properties that many natural materials do not have are realized. Such artificial materials over natural materials are referred to as "metamaterials".
The early metamaterial has single function, can only work according to a curing mode, and cannot regulate and control electromagnetic waves in real time, so the early metamaterial is called as a simulated metamaterial. Later, the metamaterial can realize dynamic control on the state of artificial atoms in the metamaterial through digital coding, so that electromagnetic waves are controlled in real time, and the metamaterial is called as an information metamaterial. In the basic structure of the information metamaterial, each 'artificial atom' can be composed of a microcircuit containing a bias diode, can realize different states such as 'on' or 'off' under different voltages, and has different responses to electromagnetic waves. In practical implementation, the artificial atoms can also be made of other materials such as triodes, graphene, temperature sensitive devices, photosensitive devices and the like. The two states of 'on' and 'off' correspond to 0 and 1 of the information world, and the metamaterial has the dynamic coding capability by configuring the units as 0 or 1. Under different codes, the information metamaterial can form electromagnetic beams with different shapes through reflection, so that the purpose of dynamically controlling electromagnetic waves is achieved. Through the depth design of the information metamaterial, the control of multiple dimensions of incident electromagnetic waves, including frequency spectrum, phase, amplitude, polarization and the like, can be realized, and conditions are created for applying the metamaterial in mobile communication.

Referring to fig. 2, in which the SSB PATTERN configuration K =4 of the gNB, the base station transmits SSB beams in 4 spatial directions one by one within the SSB transmission period T.
Here, it is assumed that M single-antenna terminals are in the cell covered by the current gbb and are ready to receive signals transmitted from the base station. An intelligent super surface with I reflection types is arranged between a terminal and a base station (for the convenience of description, the intelligent super surface is defined as a reflection type and a real type

Fig. 4 is a schematic diagram of a mechanism for periodically sending an SSB to an intelligent super-surface by a target base station in the embodiment of the present application, and as shown in fig. 4, the intelligent super-surface calculates a beam deflection weight/codebook of an RIS uplink according to an analyzed position of an uplink random access time-frequency resource indicated by the SSB of the base station, and configures the beam deflection weight/codebook on a possible random access channel according to a time corresponding to a region where the SSB is reflected at different spatial positions in an area covered by the RIS. When a terminal detects the SSB wave beam of a target cell in the region and initiates random access in the corresponding uplink resource, the RIS can reflect the random access signal of the terminal to the gNB with higher gain through wave beam forming, and the probability of the random access of the terminal is improved.
For the ascending process (terminal- > RIS- > gNB)
According to the downlink process, the signal period received by the terminal and the local beam deflection period of the ith reflection element of the intelligent reflection surface are known, namely
Assuming that the terminal responds to the base station after receiving the SSB signal of the base station under the condition that the reflection weight and the reflection angle of the intelligent reflection surface are not changed, when the uplink signal of the terminal passes through the intelligent reflection surface and returns the uplink information to the base station, the deflection angle between the corresponding reflection element and the reflection element is not changed.
In the same period, there are M terminals, ready to send signals to the base station. The base station has K total antennas for receiving signals. An intelligent reflecting surface with I reflecting elements is arranged between the terminal and the base station and used for reflecting signals of the terminal to the base station. Consider a block-fading channel, i.e., all channels remain unchanged for one time block and vary independently for different time blocks. There may be n deflection directions for the i (i =1,2.., i) reflective element of the smart reflective surface, which receives a termination signal of s' m (m＝1,2...,M)。
Within the time block of interest, p 'is used' m (m =1,2.., N) represents the signal transmission power of the mth terminal, h m (M =1,2.., M) denotes the channel of the mth terminal signal to the base station, denoted by t m,i (M =1,2, …, M; I =1,2, …, I) represents the channel of the ith reflective element, r 'from the mth terminal to the smart reflective surface' i (I =1,2.., I) represents the channel of the ith reflective element of the intelligent reflective surface to the base station,

Use of
The equivalent channel from the m terminal to the ith reflection element of the intelligent reflection surface to the base station is
Wherein C represents a complex field.
When the terminal sends the random access signal, the RIS can use the corresponding detection algorithm to carry out DOA estimation on the PREACH sent by the terminal, and more accurate direction information of the terminal is obtained. Here, the gNB should consider to adopt a method of sending PDCCH-PDSCH-PUSCH in different time slots, the RIS adopts a broadcast beam when CORESET deflection sending, meanwhile performs blind detection on DCI of a target terminal, and performs corresponding deflection on uplink and downlink time frequency resources indicated by the DCI. For the system broadcast message, the foregoing broadcast method is still adopted for deflection forwarding.
According to the embodiment of the application, the terminal in the coverage area of the RIS can receive the broadcast messages such as SSB and the like sent by the gNB through the broadcast beam provided by the RIS, and the RIS can estimate the gNB position through the broadcast signals such as SSB and the like sent by the serving cell gNB. When the terminal initiates random access and the RIS does not obtain the accurate position of the terminal, the deflection of the terminal random access signal is realized by adopting channel reciprocity.
The RIS can utilize the uplink signal of the terminal to estimate the position of the terminal in the RIS service area, and utilize the information and combine the position of the base station to select more accurate downlink and uplink beam deflection weight/codebook, thereby providing higher gain for the uplink and downlink between the gNB and the terminal.
Optionally, the method further comprises:
under the condition that the target reflection element receives the synchronous signal and the broadcast channel block signal sent by the target base station, analyzing the synchronous signal and the broadcast channel block signal, and determining first direction-of-arrival information of the target base station;
determining a first beam deflection weight for the intelligent meta-surface based on the first direction of arrival information.
Specifically, in the embodiment of the present application, the RIS may perform DOA estimation on the target base station by using the SSB signal sent by the target base station, so as to obtain more accurate azimuth information and first direction-of-arrival information of the target base station.
After the first direction of arrival information of the target base station is obtained, a first beam deflection weight of the intelligent super-surface can be further determined according to the first direction of arrival information.
The method can effectively improve the effect of a wireless channel between the target base station and the RIS, and particularly when signals between the target base station and the RIS are faded due to various factors, the mechanism can effectively compensate the fading, so that the spectrum efficiency between the target base station and the RIS is improved.
Optionally, after the determining the first direction of arrival information of the target base station, the method further includes:
under the condition that the intelligent super surface receives random access request information sent by the target terminal, second direction-of-arrival information of the target terminal is determined based on the random access request information;
determining a second beam deflection weight of the intelligent super-surface based on the first direction of arrival information and the second direction of arrival information.
Specifically, the RIS performs DOA estimation on the azimuth angle of the target terminal when deflecting the random access request signal of the target terminal, and obtains the accurate azimuth of the target terminal, that is, the second direction-of-arrival information of the target terminal.
After the target terminal is combined with the obtained position of the target base station, and the terminal is successfully accessed randomly, more accurate uplink and downlink beam deflection weight/codebook can be provided for the terminal.
In the embodiment of the application, the target base station should consider a method of sending the PDCCH-PDSCH-PUSCH in different time slots, the RIS adopts a broadcast beam when CORESET deflection sending is performed, meanwhile, blind detection is performed on DCI of the target terminal, and corresponding deflection is performed on uplink and downlink time-frequency resources indicated by the DCI. For the system broadcast message, the foregoing broadcast method is still adopted for deflection forwarding.
