[0045] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described as follows. The related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this document is for the purpose of describing the embodiments of the present application only and is not intended to be limiting of the present application.

[0047] Before explaining the present application, the RIS in the related art is described here:

[0048] Figure 2 is a schematic diagram of a model provided in the related art. As Figure 2 indicated, the signal of the network side can be reflected or transmitted via the RIS to the terminal.

[0049] Here, the RIS consists of two parts: the RIS controller that receives the control instructions sent by the network side, i.e., the gNB, and the RIS panel that reflects or transmits the uplink / downlink (DL / UL) signaling / data between the gNB and the terminal, i.e., the UE. The RIS panel can run on a common radio frequency (RF) platform.

[0050] It should be noted that the RIS-assisted communication is deployed in the network, and the working frequency band of the RIS is usually wide and can cover multiple central frequency points of communication. If the base stations of different frequency bands are co-sited, as shown in FIG. 1, Cell1 / UE 1, Cell 2 / UE 20 and Cell 2 / UE 21 belong to different frequency bands, Cell 2 communicates with UE 20 and UE 21 through beam 2, Cell 1 communicates with UE 1 through beam 1, and RIS1 is only regulated by the network of Cell 1. RIS1 determines the reflection phase according to the spatial positions of Cell 1 and UE 1 to form a directional service for UE 1. The presence of RIS1 will affect the movement of UE 20. Figure 3

[0051] Case 1: UE 20 moves from the area directly covered by the Cell 2 base station to the position of UE 1. Without RIS1, UE 2 will experience beam failure or cell handover at this time. However, at this time, the network has RIS1 controlled by Cell 1, and through the traditional beam management process, UE 20 can still maintain a good connection state.

[0052] Case 2: UE 20 moves synchronously with UE 1. Through the beam management process, Cell 1 dynamically regulates RIS1 for UE 1 so that UE 20 can obtain good signal quality and can realize the access of UE 20 to Cell 2 through the reflection beam of RIS1 and the dynamic tracking of the beam after access. However, when the synchronicity of the movement of the two is broken, UE 20 moves out of the coverage range of the beam pointing to UE 1, and a performance drop will occur.

[0053] The root cause of the above two cases is that the introduction of RIS causes the coverage range of the cell of different frequency bands to change, and as shown in FIG. 1, the closer the distance to the boundary of the coverage range, the lower the reference signal receiving power (RSRP) of the reference signal resource of the RIS receiving level corresponding to the placement position of the RIS. Among them, Figure 4 Figure 4 ​​The horizontal coordinate in the figure is the RSRP value, in units of decibel-milliwatts (dBm); and the vertical coordinate is the distance value, in units of meters (m).

[0054] It should be noted that if the inter-frequency cells belong to the same operator, the change can be coordinately controlled. However, if the inter-frequency cells belong to different operators, the change in coverage range is uncontrollable for the network of the non-RIS operator, and the network planning and neighbor configuration according to the case without inter-operator RIS cannot be updated in time, resulting in failure of the UE 20 to switch or a sharp drop in the bit error rate performance due to overly optimistic modulation and coding scheme (MCS) selection.

[0055] In the current protocol, the base station mainly considers the following aspects when making a decision on the target cell reported by the UE: whether the target cell and the serving cell have a neighbor relationship; and whether the serving cell is configured with a same-frequency or inter-frequency inter-system forbidden handover. For a neighbor cell, if it is an intra-site handover, the same-frequency / inter-frequency neighbor cell needs to be configured before the handover; if it is an inter-site handover, the external cell and the same-frequency / inter-frequency inter-system neighbor cell need to be configured before the handover. If the automatic neighbor relation (ANR) function is enabled, the intra-site handover does not need to be configured with the same-frequency / inter-frequency neighbor cell, and the inter-site handover can be normally switched as long as the external cell is configured; the UE will not measure and report the signal of the cell added to the neighbor blacklist.

[0056] Figure 5 A flowchart of a neighbor configuration method provided by an embodiment of the present application is shown in FIG. 2. As shown in FIG. 2, the method is applied to the network device 13 in the communication system 100 shown in FIG. 1, and the method includes the following steps. Figure 5 Figure 1

[0057] In step 501, the first time advance of the first terminal and the first beam where the first terminal is located are obtained.

[0058] In some embodiments, the first device estimates the first time advance of the first terminal based on the difference between the measured first terminal uplink reference signal / physical channel and the uplink time slot boundary. Of course, the first device can also receive the first time advance sent by other related devices. The present application does not make a specific limitation on the manner of obtaining the first time advance.

[0059] In some embodiments, the first beam can be a beam for transmitting first terminal related signaling. The first beam is the strongest beam among the beams covering the first terminal.

[0060] It should be noted that the present application can Figure 3 For example, the base station of Cell 2 measures the TA of the UE 20 and the UE 21, and obtains the TA values of the UE 20 and the UE 21 as shown in FIG. 3. Figure 6 ​​Tp21 and Tp21 are the propagation delays of the two users. Tp21 is the difference between the time when Cell 2 sends a DL signal and the time before UE 21 receives the DL signal. Tp20 is the difference between the time when Cell 2 sends a DL signal and the time before UE 20 receives the DL signal. The TA corresponding to UE 21 is 2*Tp21; the TA corresponding to UE 20 is 2*Tp20; the TA corresponding to UE 21 includes the sum of the difference between the time when Cell 2 sends a DL signal and the time before UE 21 receives the DL signal and the difference between the time when Cell 2 receives a UL signal from UE 21 and the time before UE 21 sends the UL signal; the TA corresponding to UE 20 includes the sum of the difference between the time when Cell 2 sends a DL signal and the time before UE 20 receives the DL signal and the difference between the time when Cell 2 receives a UL signal from UE 20 and the time before UE 20 sends the UL signal; it should be noted that the two users are located under the same beam 1, but the TA of UE 20 is obviously longer than the TA of UE 21.

[0061] Step 502, obtaining a first interval corresponding to the first beam.

[0062] The first interval includes a dynamic range of time advance in a coverage range of the first cell; the first terminal includes a terminal camping on the first cell, a terminal pre-reselecting to the first cell, or a terminal pre-handover to the first cell.

[0063] In some embodiments, a historical time advance of a terminal is obtained; the terminal includes the first terminal; the historical time advance is associated with a beam corresponding to the terminal to obtain statistical data of time advance under different beams; the beam includes the first beam; based on the statistical data, an interval corresponding to each beam is determined; the interval includes the first interval.

[0064] In the embodiments of the application, the statistical data includes but is not limited to a probability distribution and a statistical quantity.

[0065] In the embodiments of the application, the association of the historical time advance and the beam corresponding to the terminal means that the historical time advance and the beam are analyzed and counted, the association between the two is analyzed, and then the statistical data is obtained. It should be noted that the management of TA in the current protocol is based on a Medium Access Control (MAC) control element (CE), and is not associated with the beam. In the application, the TA and the beam are associated, compared with the terminal to determine and report, and the base station end can more accurately depict the effective coverage range under different beams through a large number of and long-term TA measurements.

[0066] Step 503, determining a region of the first terminal based on the first time advance and the first interval.

[0067] Different regions have different probabilities of being affected by uncontrollable intelligent metasurfaces.

[0068] In this embodiment, the probability of being affected by the uncontrollable smart metasurface varies for different regions, that is, the degree of influence of the uncontrollable RIS on different regions is different. For example, it has no effect on the terminal in the first region, but has an effect on the terminals in the second and third regions.

[0069] In some embodiments, if the first time advance is within the first interval, and the first time advance is less than the cyclic prefix value, and the duration corresponding to the first time advance is greater than the first time threshold, the area of ​​the first terminal is determined as the first region; wherein, the first region includes the area located within the planned coverage area of ​​the first cell and outside the coverage area of ​​the uncontrollable smart metasurface.

[0070] In some embodiments, if the first time advance is outside the first interval, and the first time advance is less than the cyclic prefix value, and the duration corresponding to the first time advance is greater than the first time threshold, the area of ​​the first terminal is determined to be the second area; wherein, the second area includes the overlapping area of ​​the planned coverage area of ​​the first cell and the coverage area of ​​the uncontrollable smart metasurface.

[0071] In some embodiments, if the first time advance is outside the first interval, and the first time advance is greater than the cyclic prefix value, and the duration corresponding to the first time advance is greater than the first time threshold, the area of ​​the first terminal is determined to be the third area; wherein, the third area includes the area located outside the planned coverage area of ​​the first cell and within the coverage area of ​​the uncontrollable smart metasurface.

[0072] It should be noted that, using the region determination method in this application, if Figure 6 If the TA of UE20 is outside the first interval, it can be preliminarily determined that UE20 is located in an uncontrollable extended coverage area, namely the second or third area.

[0073] Step 504: Configure neighboring cells based on the region.

[0074] In some embodiments, if the region of the first terminal is the second region, the switching beam of the uncontrollable smart metasurface is reselected, and a stronger beam with a timing advance within the first interval is selected as much as possible.

[0075] In some embodiments, if the region of the first terminal is the second region, the modulation and coding strategy level corresponding to the channel quality indication reported under the second beam is reduced; the second beam is the beam with the strongest signal actually measured for smart metasurface reflection.

[0076] In some embodiments, if the region of the first terminal is a second region or a third region, and the first terminal needs to perform cell handover, the first terminal performs measurements and sends a measurement report and precoding control instructions for all detected cells to the first device; the first device receives the measurement report and precoding control instructions for all detected cells sent by the first terminal. If the precoding control instruction for the second cell is not in the pre-stored neighbor cell list, the first device sends an automatic neighbor cell relationship function request to the first terminal; wherein, the automatic neighbor cell relationship function request is used to obtain the cell global identification code of the second cell to identify the second cell; the second cell is included in all detected cells.

[0077] The specific representation of the measurement report in the embodiments of this application may include at least one of the following: RSRP, received signal strength indicator (RSSI), reference signal received quality (RSRQ), signal to interference noise ratio (SINR), etc., and no specific limitation is made here.

[0078] In some embodiments, if the area of ​​the first terminal is the second or third area, the difficulty of initiating cell reselection measurement is reduced.

[0079] Here, reducing the difficulty of initiating cell reselection measurements can be achieved through step A1 or step A2:

[0080] Step A1: The first device sends a first message to the first terminal; here, the first message can be a new system message or an indication message.

[0081] The first message is used to instruct the first terminal to perform a cell reselection measurement; the first message includes one or more of the following: the maximum measurement start threshold value; the minimum cell reselection hysteresis value.

[0082] It should be noted that the maximum measurement initiation threshold can be set to infinity. The minimum cell reselection hysteresis value can be set to 0.

[0083] It should be noted that the first device can first determine whether the signal quality of one or more serving cells it is working on meets the measurement start conditions, and then take corresponding actions based on the determination results.

[0084] Step A2: The first device sends a system message including the newly added bits to the first terminal.

[0085] The newly added bit is used to instruct the first terminal to perform a cell reselection measurement; the system message includes one or more of the following: the maximum measurement start threshold; the minimum cell reselection hysteresis value.

[0086] This application provides a neighbor cell configuration method. A first device obtains a first timing advance of a first terminal and a first beam in which the first terminal is located; obtains a first interval corresponding to the first beam; wherein, the first interval includes the dynamic range of timing advance within the planned coverage area of ​​the first cell; the first terminal includes a terminal camped in the first cell, a terminal pre-selected to the first cell, or a terminal pre-handover to the first cell; based on the first timing advance and the first interval, the region of the first terminal is determined; wherein, different regions correspond to different probabilities of being affected by uncontrollable smart metasurfaces; based on the region, neighbor cell configuration is performed. That is, this application determines the region where the terminal is located by calculating the first timing advance of the first terminal and comparing the first timing advance with the first interval, and determines whether the UE can be affected by uncontrollable smart metasurfaces based on the region. Thus, different neighbor cell configurations are performed for different judgment results. This solves the problem in related technologies that when a RIS schedules a terminal that is different from the operator network of the RIS, it may lead to scheduling failure or a sudden drop in performance.

[0087] To address the impact of uncontrollable RIS (Restricted Information Provider) events from different operators on users within the same cell, this application proposes a method for identifying uncontrollable RIS. The basic idea is to correlate the beam with a large amount of historical timing advance (TA) data, calculate the TA to determine whether the UE has been affected by uncontrollable RIS, and then configure neighboring cells accordingly. The method of this application includes two phases: Phase One and Phase Two.

[0088] Phase 1: Statistical / Training Phase Using Historical Data

[0089] Step 1: For all terminals camping / reselecting / handing over to this cell, the base station measures the difference between its uplink reference signal / physical channel and the uplink timeslot boundary to estimate the timing advance (TA) of all terminals in the cell.

[0090] Step 2: The base station determines the beam of the terminal that will camp / reselect / switch to the cell through the beam management process.

[0091] Step 3: The base station performs data analysis and statistics on the large amount of historical TA data measured above and the corresponding beams to obtain the probability distribution and statistics of TA under different beams.

[0092] Step 4: Repeat steps 1-3 over a longer period to obtain long-term statistics of TA under each beam and determine the first interval under each beam.

[0093] The first interval refers to the dynamic range of the terminal's local area (TA) within the planned coverage area of ​​the cell. The first interval can be obtained through the following methods:

[0094] Machine learning methods use collected data to train models. For example, the model input is the TA value and beam of a certain terminal, and the output is the probability that the terminal is within the planned range. Alternatively, the model input is the beam and the probability that the terminal is within the planned range, and the output is the range of TA.

[0095] Statistical methods, for example, if TA follows a mean of μ and a variance of σ. 2 If the distribution is normal, the probability of falling outside the range (μ-2σ, μ+2σ) is 5%, and the probability of falling outside the range (μ-3σ, μ+3σ) is 0.3%. The probability settings for low-probability events can be adjusted according to the degree of influence of uncontrollable RIS.

[0096] Step 5: The base station obtains the TA value and the beam in which the terminal is located, and compares its TA value with the first interval under the beam. The comparison TA satisfies one of the following conditions and the duration exceeds a first time threshold; wherein, the first time threshold is used to avoid TA jitter caused by occasional events, which may include uncontrollable RIS temporary directional beams emitted by the RIS towards users in the served cell.

[0097] 1) If the TA is located within the first interval and the terminal TA is less than the cyclic prefix (CP) value: the base station determines that the terminal is only located within the cell planning coverage area, which is recorded as the first area.

[0098] 2) If the TA is located outside the first interval and the TA of the terminal is less than the cyclic prefix (CP) value: the base station determines that the terminal is located in the overlapping area of ​​the uncontrollable RIS and the theoretical coverage area of ​​the cell (ensuring that there is no inter-symbol interference in the uplink signals of different terminals), which is denoted as the second region.

[0099] 3) If the TA is located outside the first interval and the terminal's TA is greater than the cyclic prefix (CP) value: the base station determines that the terminal is located within the uncontrollable RIS coverage area and outside the theoretical coverage area of ​​the cell (there is inter-symbol interference in the uplink signals of different terminals), and it is recorded as the third region.

[0100] Phase 2: Transmitting data to a specific terminal using statistical / training results.

[0101] Step 6a: Based on the above decision, to prevent the impact of uncontrollable RIS beam switching on the second area terminal, one of the following two methods can be adopted:

[0102] Re-perform the beam management process, selecting the strongest beam possible that has its TA (Target Aspect Ratio) within the first interval.

[0103] Based on the MCS level corresponding to the Channel Quality Indicator (CQI) reported under the strongest measured beam (RIS reflection), the MCS level is appropriately reduced to ensure relatively reliable transmission.

[0104] Step 6b: Based on the above decision, for terminals residing in the second and third areas, reduce the difficulty of initiating cell reselection measurement and improve the success rate of reselection to other cells.

[0105] Step 6c: Based on the above decision, if the terminals in the second and third areas meet the cell handover conditions, uncontrollable coverage extension may occur, leading to changes in neighbor cell relationships. Terminals in the second area (meeting handover conditions) and the third area report measurement reports and all monitored Precoding Control Indications (PCIs) according to measurement control. If the reported PCI is not in the neighbor cell list defined by the serving base station, the serving base station initiates an Automatic Neighbor Relation (ANR) function request to the terminal to obtain the Cell Global Identity (CGI) of the cell to identify neighbor cells.

[0106] This application may Figure 3 Taking the scenario in the example, if terminal UE20 is in a disconnected state, UE20 measures the SSB signal strength and detects MIB and SIB1 messages, assuming that the cell selection conditions are met in the second area. UE20 sends a preamble, the base station measures the initial TA value, and uses step 5 to determine that UE20 is located in the second area.

[0107] Currently, according to the protocol, cell reselection measurement initiation requires the following conditions to be met, depending on whether the cell is on the same frequency, or on a different frequency / system: S rxlev ≤S intrasearchp or S nonintrasearchp ,in,

[0108] S rxlev ≤Q rxlevmeas -(Q relavmin +Q relavminoffset )-P compensation -Q offsettemp

[0109] For the re-election of the community

[0110] Q rxlevmeas For the measured RSRP; Q relavminThe minimum received signal level for the cell is q-RxLevMin or q-RxLevMinSUL in SIB1, q-RxLevMin in SIB2 for co-frequency neighboring cells, SIB4 for inter-frequency neighboring cells, and SIB5 for inter-system neighboring cells; Q relavminoffset This is the minimum access level offset for a cell, a value that makes a cell more difficult to select. It corresponds to q-RxLevMinOffset in SIB1, and q-RxLevMinOffsetCell for co-frequency neighbor cells SIB3, inter-frequency neighbor cells SIB4, and inter-system neighbor cells SIB5; P compensation This is the uplink power compensation value; This is a temporary offset, a penalty factor introduced during RRC establishment to address multiple T300 timeouts. Currently, the protocol uses the R criterion (Rn>Rs) to make reselection decisions for neighboring cells that satisfy the S criterion.

[0111] Without changing the frequency reselection priority configuration, in order to enable UE20 to start measurement and cell reselection as soon as possible and reduce the reselection difficulty for UE20, one of the following configurations can be performed for terminals in unknown coverage areas:

[0112] 1) Send new system messages, which may include a higher measurement start threshold or infinity, and a smaller cell reselection hysteresis.

[0113] 2) Add a 1-bit indicator field to the existing system messages to indicate whether the terminal always performs cell reselection measurements, i.e., set the measurement start threshold to infinity and 0dB cell reselection hysteresis.

[0114] Alternatively, the q-RxLevMinOffset in the current cell SIB1 can be appropriately increased, while the q-RxLevMinOffsetCell in SIB3 / 4 / 5 can be decreased.
