Specifically, the network side device may determine at least one second codebook from the at least one measured codebook based on channel quality information corresponding to different measured codebooks, and further determine the number of the corresponding second codebooks and/or at least one second codebook index based on the at least one second codebook.
Of course, in some embodiments, the target information comprises time domain information of the first reference signal. In this embodiment, in a case where the target data includes channel measurement information, the determining target information based on the target data includes:
determining a first reference signal from a plurality of reference signals of the network side equipment based on the channel quality information;
time domain information of the first reference signal is determined.
In this embodiment, a network side device configures measurement resources, and instructs, through measurement indication, a target device to perform channel quality measurement on the measurement resources configured by the network side device based on at least one measurement codebook, so as to obtain channel quality information. And the target equipment sends the channel quality information to the network side equipment so that the network side equipment can determine the target information based on the channel quality information. Through the arrangement, in the process of cooperatively determining the first reference signal by the target device and the network side device, the first reference signal is conducted by the network side device, so that the determined first reference signal is more in line with the actual situation of the network side device.
It should be understood that, when transmitting the reference signal, the network side device generally adopts a form of reference signal scanning, and transmits a reference signal in one direction at each moment in one period, and the coverage of the terminal device in the cell is completed by the reference signals in different directions transmitted at different moments. Thus, the specific time instant of the first reference signal transmission can be determined by the time domain information of the first reference signal.
It should be understood that the specific manner in which the network side device determines the second codebook information is not limited herein. For example, in some embodiments, the network-side device determines the second codebook information based on information of a position, an orientation, etc. of the reflective unit array when accessing the network. In other embodiments, the network side device determines the second codebook information based on a difference between any two first reflective codebooks. In other embodiments, the network side device determines the second codebook information based on the total number of resources.
It should be appreciated that the second codebook information includes a second codebook number, and/or at least one second codebook index. The second codebook index is used to determine a second codebook, which may be understood as a phase matrix used by the target device to reflect or forward the first reference signal.
It should be understood that the number of second codebook included in the target information is not limited herein, i.e., the number of second codebook indexes included in the target information is not limited herein. For example, in some embodiments, the number of second codebook indices is one or two. In other embodiments, the number of second codebook indices is a plurality. In the case that the number of the first reference signals is plural, the second codebook index corresponding to each first reference signal may be the same or different.
And the network side equipment sends a reflection instruction to the target equipment, wherein the reflection instruction carries the target information. And the target equipment receives the reflection indication sent by the network side equipment. The target device reflects or forwards the first reference signal based on the target information.
It should be understood that the target device controlling the reflective element array based on the time domain information of the first reference signal may be understood that the target device adjusts the phase matrix of the reflective element array at a time corresponding to the first reference signal based on the time domain information of the first reference signal.
It should be understood that the target device controlling the reflective element array based on the second codebook information may be understood that the target device adjusts the phase matrix of the reflective element array based on the second codebook information, thereby adjusting the angle of the reference signal reflected by the reflective element array.
It should be understood that, the target device reflects the first reference signal based on the target information, so that the reflection unit array may adjust to the phase matrix corresponding to the first reference signal at the time corresponding to the first reference signal, so that the reflection unit array reflects the first reference signal to obtain the reflected reference signal with a specific angle.
Optionally, in some embodiments, the number of the second codebooks is K, where K is a positive integer;
the sending a reflection indication to the target device includes:
under the condition that K is larger than 1, configuring K-1 second reference signals based on the first reference signals, wherein the K reference signals are in one-to-one correspondence with the K second codebooks, and the K reference signals comprise one first reference signal and K-1 second reference signals;
and sending a reflection indication to the target equipment, wherein the reflection indication carries time domain information of the K reference signals and K second codebooks.
It should be understood that the number of second codebooks may be understood as the number of reflected reference signals and/or forwarded reference signals obtained by reflecting and/or forwarding the first reference signals by the reflective antenna array. In a specific implementation, the reflective antenna array can only correspond to one second codebook at a time, so that in the case that the number of the second codebooks is greater than 1, the network side device needs to configure K-1 second reference signals based on the first reference signals.
It should be understood that, for any one of the first reference signals, the number of the first reference signals is 1, the number of the second reference signals corresponding to the first reference signals is K-1, and the sum of the numbers of the first reference signals and the second reference signals is K, so that the K reference signals correspond to the K second codebooks one by one.
It should be understood that, when the number of the first reference signals is plural, the corresponding second reference signals of the plural first reference signals need to be configured when the number of the second codebook is greater than 1. And the number of second reference signals corresponding to each first reference signal may be the same or different.
The network side device sends the time domain information of the K reference signals and the K second codebooks to the target device, and the target device can reflect or forward the reference signals according to the time domain information of the K reference signals and the second codebooks corresponding to each reference signal.
Specifically, the target device reflects or forwards the reference signal according to a second codebook corresponding to the reference signal at a time corresponding to each reference signal in the K reference signals based on time domain information of the K reference signals, so as to obtain a reflected reference signal or a forwarded reference signal with a specific angle.
In this embodiment, when the number of second codebooks is greater than 1, the network side device configures K-1 second reference signals based on the first reference signals, where the K reference signals are in one-to-one correspondence with the K second codebooks, and the network side device sends a reflection indication to the target device, where the reflection indication carries time domain information of the K reference signals and the K second codebooks. Through the arrangement, the number of the second codebooks corresponding to the first reference signals can be multiple, so that the number of the reference signals reflected or forwarded by the reflecting unit array is increased, and the coverage capacity of the reference signals to the terminal equipment is further improved.
Optionally, in some embodiments, before the network side device sends the reflection indication to the target device, the method further includes the following steps:
judging whether the number of the reference signals of the network side equipment is increased or decreased;
and modifying the resource configuration information corresponding to the reference signals of the network side equipment under the condition that the number of the reference signals of the network side equipment is increased or decreased.
Before the network side equipment sends the reflection indication to the target equipment, the network side equipment judges whether the number of the reference signals is increased or decreased, and when the number of the reference signals of the network side equipment is increased or decreased, the resource configuration information corresponding to the reference signals of the network side equipment is modified so that the resource configuration information corresponding to the reference signals is matched with the number of the reference signals. Under the condition that the number of the reference signals of the network side equipment is unchanged, the resource configuration information corresponding to the reference signals of the network side equipment does not need to be modified.
It should be understood that the specific method for determining whether the number of reference signals of the network side device is increased or decreased is not limited herein. For example, in some embodiments, in a case where the number of second codebooks corresponding to the first reference signal is greater than 1, the network side device configures the second reference signal based on the first reference signal at this time, so the number of reference signals of the network side device may be considered to be increased.
In other embodiments, the network side device may delete the reference signals that satisfy the preset deletion condition, where the number of reference signals of the network side device is reduced, and the specific content of the preset deletion condition is not limited herein.
It should be understood that the specific method for modifying the resource configuration information corresponding to the reference signal of the network side device is not limited herein. According to the different types of the resources corresponding to the reference signals, the specific methods for modifying the resource configuration information are different. In some embodiments, the resource type corresponding to the reference signal may also be referred to as a signal type.
For example, in some embodiments, the resource or the signal type corresponding to the reference signal is any one of the following: a synchronization signal/physical broadcast channel signal block (Synchronization Signal and PBCH block, SSB), a primary synchronization signal (Primary Synchronization Signal, PSS), a secondary synchronization signal (Secondary Synchronization Signal, SSS), a physical downlink control channel (Physical Downlink Control Channel, PDCCH), a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).
Specifically, in some embodiments, the network side device typically performs initial access through synchronization signal/physical broadcast channel block (SS/PBCH block, synchronization Signal/Physical Broadcast Channel Block) resources. In this embodiment, modifying the resource configuration information corresponding to the reference signal of the network-side device may be understood as modifying the SSB configuration information indicated in the system information block (System Information Block, SIB) or the radio resource control (Radio Resource Control, RRC).
In this embodiment, before sending a reflection instruction to the target device, the network side device determines whether the number of reference signals of the network side device increases or decreases; and modifying the resource configuration information corresponding to the reference signals of the network side equipment under the condition that the number of the reference signals of the network side equipment is increased or decreased. Through the setting, the resource configuration information is matched with the reference signal condition of the network side equipment.

For easy understanding, two specific embodiments will be taken as examples, and specific flows of the reference signal management method provided in the embodiments of the present invention will be described below.
It is first noted that in the first and second embodiments, the target device includes an RIS and an intelligent reflection surface controller (RISC). The RIS in the target device can reflect or forward the reference signal, the RIS in the target device can complete operations such as receiving, decoding and executing control information sent by the network side device, and the basic configuration of the RIS can be reported to the network side device.
In the present embodiment, reflection of the reference signal by the RIS will be described as an example. In specific implementation, the RIS codebook can be adjusted by RISC, and the incident reference signal can be reflected by adjusting the RIS codebook, so as to obtain the reflected reference signal in a specific direction.
In the first embodiment and the second embodiment, the RIS/RISC has already been connected to the network side device to complete synchronization, the network side device may perform transmission of the control link to the RISC through the air interface, and the network side device may control the codebook of the RIS by using the RISC through the indication of the control link.
In the first and second embodiments, the network side device performs initial access through SS/PBCH block resources, so that the resources corresponding to the network side device are SSB resources. Of course, in other embodiments, the resources corresponding to the network side device may also be other types of resources.
Example 1
Please refer to fig. 4 and 5. As shown in fig. 4, the network-side device 41 is configured with four SSB resources, respectively denoted as SSB1, SSB2, SSB3, and SSB4, which perform reference signal scanning using four different reference signals, respectively, whose reference signal indexes are denoted as b1, b2, b3, and b4, respectively. For convenience of description, corresponding reference signals will be described below with reference signal indexes.
As shown in fig. 5, the network side device 41 configures measurement resources under different reference signals based on information such as azimuth, heading, etc. when the RIS accesses the network. The network side device 41 then sends a measurement indication to the RISC over the control channel, the measurement indication being used to instruct the RISC to take channel quality measurements on multiple measurement resources using the same or different measurement codebooks.
In this embodiment, each reference signal corresponds to one measurement resource, and the RISC adjusts the measurement codebook of the RIS so that the RIS performs channel quality measurement on each measurement resource to obtain channel quality information corresponding to each reference signal, where the number of measurement codebooks corresponding to each measurement resource is 1.
The RISC reports the channel quality information to the network side device 41 via the feedback link. Wherein, the channel quality information corresponding to different measurement codebooks is different. The network side device 41 determines that the reference signals are b1 and b2 according to the channel quality information reported by the RISC, and the measurement codebook is the second codebook corresponding to b1 and b2 because the measurement resources corresponding to b1 and b2 correspond to one measurement codebook. The network side can determine the number of the second codebooks and/or the second codebook index, namely the second codebook information, based on the second codebook.
The network side device 41 transmits the time domain information of SSB1 corresponding to b1, the time domain information of SSB2 corresponding to b2, the second codebook information corresponding to b1, and the second codebook information corresponding to b2 to the RISC. Since the number of measurement codebooks corresponding to b1 is 1, the network side device 41 determines that the number of second codebooks corresponding to b2 is also 1, and the number of measurement codebooks corresponding to b2 is 1, so the network side device 41 determines that the number of second codebooks corresponding to b1 is also 1, and therefore, in this embodiment, the number of reference signals of the network side device 41 is not increased.
In this embodiment, the time domain information of SSB1 and SSB2 includes a system frame where a Burst Set (Synchronization Signal Burst Set, SS Burst Set) of synchronization signals is located, a number of subframes, the number of SSBs existing in one SS Burst Set, a symbol number of a first orthogonal frequency division multiplexing (Orthogonal frequency division multiplex, OFDM) symbol of each SSB in the time domain (within one half frame), and a repetition period of the SS Burst Set.
The network-side device 41 scans with b1 at the time domain position of SSB1 and scans with b2 at the time domain position of SSB 2. The RIS controls the codebook of the RIS to be a second codebook corresponding to b1 at the time domain position corresponding to the SSB1, so that the RIS reflects the b1 according to the second codebook corresponding to b1 to obtain a corresponding reflection reference signal, and the corresponding reflection reference signal is recorded as RIS_b1. The RIS controls the codebook of the RIS to be a second codebook corresponding to b2 at the time domain position corresponding to the SSB2, so that the RIS reflects the b2 according to the second codebook corresponding to b2 to obtain a corresponding reflection reference signal, and the corresponding reflection reference signal is recorded as RIS_b2.
As shown in fig. 4, by reflection of the reference signal by the RIS, the terminal device 42 can search the signal of the SSB1 at the time domain position of the SSB1 and the signal of the SSB2 at the time domain position of the SSB2, so that the coverage capability of the reference signal of the network side device 41 is improved and the network access efficiency of the terminal device 42 is improved by the reference signal management method provided by the embodiment of the present invention.
Example two
Please refer to fig. 6 and 7. As shown in fig. 7, the network-side device 61 is configured with four SSB resources, respectively denoted as SSB1, SSB2, SSB3, and SSB4, which perform reference signal scanning using four different reference signals, respectively, whose reference signal indexes are denoted as b5, b6, b7, and b8, respectively. For convenience of description, corresponding reference signals will be described below with reference signal indexes.
As shown in fig. 7, the RISC searches the reference signal of the network side device 61, and can search b5 and b6, and by calculating the signal strengths of b5 and b6, only the signal strength of b5 meets the rule of reflection, so that the RISC determines b5 as the reference signal index, and can determine a unique one based on b 5.
For B5, the RISC determines that the number of the first codebooks corresponding to B5 is 2, and the codebook indexes thereof are respectively marked as a reflection codebook a and a reflection codebook B. And the RISC reports the reference signal index and the first codebook information to the network side equipment through a feedback link. Specifically, the RISC reports B5, the reflection codebook a, and the reflection codebook B to the network side device 61 through the feedback link.
The network side device 61 evaluates the reference signal index and the first codebook information reported by the RISC based on the SSB resources, and if the total number exceeds the SSB total number of resources, prunes the first codebook number. In the present embodiment, the number of the first codebooks is smaller than the SSB total resource number, so the network side device 61 determines both the reflective codebook a and the reflective codebook B as the second codebook. Second codebook information is determined based on the reflective codebook A and the reflective codebook B. Specifically, the number of second codebooks is 2, and the second codebook index is a reflective codebook a and a reflective codebook B.
Since the number of second codebooks is greater than 1, the network-side device 61 configures 1 second reference signal based on b5 and allocates new SSB resources. As shown in fig. 6, the second reference signal configured based on b5 is denoted as b5', and the SSB resource corresponding to b5' is denoted as SSB5. In this embodiment, the second codebook corresponding to B5 is the reflective codebook a, and the second codebook corresponding to B5' is the reflective codebook B. The network side device 61 transmits the time domain information of SSB1 corresponding to B5, the time domain information of SSB5 corresponding to B5', and the reflection codebook B corresponding to B5 and the reflection codebook a corresponding to B5' to the target device.
Since the number of reference signals of the network-side device 61 increases, the network-side device 61 needs to modify the corresponding resource configuration information. In this embodiment, the network side device may modify the configuration information in SIB1 or the configuration information in RCC, such as
SIB1- > ServerCellConfigSIB- > ssb-PositionInBurst or
ServingCellConfigCommon->ssb-PositionsInBurst。
Network side device 61 scans with b5 at the time domain position of SSB1 and scans with b5' at the time domain position of SSB 5.RISC controls the code book of RIS to be the reflection code book A corresponding to b5 at the time domain position corresponding to SSB1, so that RIS reflects b5 according to the reflection code book A to obtain a corresponding reflection reference signal, which is marked as RIS_b5.RISC controls the code book of RIS to be the reflection code book B corresponding to B5' at the time domain position corresponding to SSB5, so that RIS reflects B5' according to the reflection code book B to obtain a corresponding reflection reference signal, which is marked as RIS_b5'.
As shown in fig. 6, by reflection of the reference signal by the RIS, the terminal device 62 may search for the signal of the SSB1 at the time domain position of the SSB1 and may search for the signal of the SSB5 at the time domain position of the SSB 5.
