[0002] This application claims priority to Chinese Patent Application No. 202510133909.2, filed on February 6, 2025, entitled "Method, Apparatus, Electronic Device and Storage Medium for Determining Cell Status", and Chinese Patent Application No. 202510133909.2, filed on April 27, 2025, entitled "Method, Apparatus, Electronic Device and Storage Medium for Determining Cell Status", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This application belongs to the field of communication technology, and specifically relates to a method, apparatus, electronic device and storage medium for determining cell status. Background Technology
[0004] In existing technologies, the main idea of network energy saving technology is to reduce the transmission of unnecessary information through network-side devices or terminals without affecting terminal services or system performance, so as to achieve energy saving of network-side devices and / or terminals.
[0005] Taking 5G as an example, network-side equipment can change the periodically sent System Information Block 1 (SIB1) to On-Demand SIB1 (OD-SIB1), and can also change the periodically sent Other System Information (OSI) to On-Demand OSI (OD-OSI). Terminals supporting OD-OSI or OD-SIB1 can send a System Information (SI) request message to the network-side equipment to request the network-side equipment to send SIB1 or OSI. When a terminal receives a Random Access Response (RAR) from the network-side equipment, and the Random Access Preamble ID (RAPID) carried in the RAR matches the Random Access Preamble ID when the terminal sent the request, the terminal will receive the SIB1 or OSI sent by the network-side equipment within a preset time period.
[0006] When the first cell changes from normal mode to energy-saving mode (e.g., changing the periodically transmitted SIB1 to OD-SIB1), ordinary terminals cannot obtain SIB1 and therefore cannot camp on the first cell. However, for some terminals that support energy-saving technologies, such as those supporting OD-SIB1, they must first search for and camp on normal neighboring cells. From these neighboring cells, they receive the configuration information corresponding to the first cell, such as Up Link Wake-Up signal (UL WUS) configuration or on-demand SIB1 request configuration. Based on the UL WUS configuration or on-demand SIB1 request configuration, they send a system information request message to the first cell to obtain the SIB1 sent by the first cell within a preset time period according to the system information request message, thus completing camping on the first cell.
[0007] The above process requires these terminals to undergo reselection twice (or even more times), which is complex and will increase terminal power consumption, which is not conducive to energy saving of the terminals. Moreover, since these terminals need to re-request On-Demand SIB1, the first cell needs to respond to the On-Demand SIB1 request, which is also not conducive to energy saving of network-side equipment. Summary of the Invention
[0008] This application provides a method for determining cell status, which can solve the problem that terminals supporting energy-saving technology need to go through two reselection processes before they can normally camp on the first cell that changes from normal mode to energy-saving mode, thus hindering energy saving for terminals and network-side equipment.
[0009] In a first aspect, a method for determining cell status is provided, executed by a terminal. The method includes: obtaining target indication information or target configuration information from a first cell or a second cell; determining the cell access status when the first cell is in energy-saving mode based on the target indication information or the target configuration information; wherein the cell access status includes allowed access or prohibited access, and whether the first cell is in energy-saving mode is determined by the terminal based on at least one of the target configuration information, the synchronization signal of the first cell, and the system message of the first cell.
[0010] Secondly, a method for determining cell status is provided, executed by a network-side device. The method includes: sending target indication information or target configuration information from a first cell or a second cell to a terminal, wherein the target indication information or the target configuration information is used by the terminal to determine the cell access status when the first cell is in energy-saving mode; wherein the cell access status includes allowed access or prohibited access, and whether the first cell is in energy-saving mode is determined by the terminal based on at least one of the target configuration information, the synchronization signal of the first cell, and the system message of the first cell.
[0011] Thirdly, an apparatus for confirming cell status is provided, applied to a terminal. The apparatus includes: an acquisition module for acquiring target indication information or target configuration information from a first cell or a second cell; and a determination module for determining the cell access status when the first cell is in energy-saving mode, based on the target indication information or the target configuration information. The cell access status includes allowed access or prohibited access, and whether the first cell is in energy-saving mode is determined by the terminal based on at least one of the target configuration information, the synchronization signal of the first cell, and the system message of the first cell.
[0012] Fourthly, an apparatus for confirming cell status is provided, applied to network-side equipment. The apparatus includes: a sending module, configured to send target indication information or target configuration information from a first cell or a second cell to a terminal, wherein the target indication information or the target configuration information is used by the terminal to determine the cell access status when the first cell is in energy-saving mode; wherein the cell access status includes allowed access or prohibited access, and whether the first cell is in energy-saving mode is determined by the terminal based on at least one of the target configuration information, the synchronization signal of the first cell, and the system message of the first cell.
[0013] Fifthly, a terminal is provided, the terminal including a processor and a memory, the memory storing a program or instructions executable on the processor, the program or instructions, when executed by the processor, implementing the steps of the method as described in the first aspect.
[0014] In a sixth aspect, a network-side device is provided, the network-side device including a processor and a memory, the memory storing a program or instructions executable on the processor, the program or instructions, when executed by the processor, implementing the steps of the method as described in the second aspect.
[0015] In a seventh aspect, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect, or implement the steps of the method described in the second aspect.
[0016] One of the above technical solutions has the following advantages or beneficial effects: it can determine the cell access status of the first cell when it is in energy-saving mode according to the target indication information or the target configuration information, so that when the first cell changes from normal mode to energy-saving mode, the terminal supporting energy-saving technology can stay in the first cell in energy-saving mode without having to go through multiple reselections, which is beneficial to energy saving of terminal and network side equipment.

[0042] The inventors of this application have discovered that, although related technologies allow terminals supporting energy-saving technologies to continue camping in the first cell that transmits non-Cell Defining Synchronization Signal Blocks (NCD-SSBs), the terminal cannot obtain the relevant information from the NCD-SSBs that enables it to receive SIB1 normally from the first cell, thus leading to the aforementioned technical problem. This application provides a method for determining cell status, which enables terminals supporting energy-saving technologies to camp in the first cell in energy-saving mode without having to undergo multiple reselections when the first cell changes from normal mode to energy-saving mode, thus facilitating energy saving for both the terminal and network-side equipment.
[0043] The method for determining cell status provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0044] Figure 2 shows a flowchart of a method for determining cell status provided in an embodiment of the present disclosure. The method can be applied to a terminal. As shown in Figure 2, the method may include the following steps.
[0045] In step S101, target indication information or target configuration information is obtained from the first cell or the second cell.
[0046] The first cell can be a cell that has changed from normal mode to energy-saving mode. The target indication information can be indication information related to the energy-saving mode of the first cell. The target configuration information can be configuration information related to the energy-saving mode of the first cell. The second cell can be a cell that can send target configuration information or target indication information. For example, it can be a neighboring cell of the first cell. Of course, it can also be a cell that is not a neighboring cell of the first cell. This application does not limit this. It is understood that the first cell is also a cell that can send target configuration information and target indication information.
[0047] Target indication information includes at least one of the following:
[0048] The first indication information is used to indicate that the terminal is allowed to access the first cell when it is in energy-saving mode. For example, the first indication information may be a terminal camping indication that allows the terminal to access the first cell when it is in energy-saving mode.
[0049] The second indication information is used to indicate that the system message of the first cell includes target configuration information. For example, the second indication information may be an indication that the system message of the first cell in energy-saving mode includes the presence of the UL WUS configuration of the first cell.
[0050] The third indication information is used to indicate whether SIB1 of the first cell has been scheduled.
[0051] The target configuration information includes at least one of the following:
[0052] Wake-up signal UL WUS configuration;
[0053] First system information block SIB1 receives configuration;
[0054] SIB1 configuration requests are made on demand;
[0055] The first system information block SIB1 receiving configuration is used by the terminal to receive SIB1 when the first cell is in energy-saving mode.
[0056] In some embodiments, the terminal may be a terminal that supports at least one of the following features:
[0057] Network energy-saving NES;
[0058] Request OD-SIB1 on demand;
[0059] Request OD-SSB from the on-demand synchronization signal block SSB;
[0060] On-demand tracking of reference signal TRS requests OD-TRS;
[0061] Discontinuous transmission of DTX in the cell;
[0062] Discontinuous reception DRX in the cell;
[0063] NES-based conditional switching;
[0064] Random access adaptive RACH adaptation;
[0065] Paging adaptation;
[0066] SSB adaptation.
[0067] In some embodiments, the target configuration information is obtained from a first system message from the first cell. For example, the terminal can obtain the target configuration information from the first cell when the first cell is in normal mode.
[0068] In another embodiment, the target configuration information may also be obtained from the first system message from the second cell. For example, the terminal may obtain the target configuration information of the first cell from the second cell while camped in the second cell and save the target configuration information. After reselecting to the first cell, if it is determined that the target configuration information is still valid (for example, the value tag corresponding to the target configuration information has not changed), it does not need to obtain it again from the first cell.
[0069] In some embodiments, the target indication information is obtained from a second system message or short message from the first cell. The first system message and the second system message may be the same system message or different system messages. For example, the terminal may obtain the second indication information from system message A (e.g., the system message in which the first cell is in energy-saving mode includes an indication of the presence of the UL WUS configuration of the first cell) and obtain the target configuration information (e.g., the UL WUS configuration of the corresponding first cell) from system message B.
[0070] In some embodiments, at least one of the target configuration message, the first indication information, or the second indication information is obtained from an RRC message from the first cell or the second cell.
[0071] The first system message and the second system message can be any of MIB (Master Information Block), SIB1, RMSI (Remaining Minimum System Information), or OSI. The types of the first system message and the second system message can be the same or different. For example, the first system message can be SIB1 / RMSI, while the second system message is OSI. This application does not impose any restrictions on this.
[0072] In step S102, the cell access status of the first cell in energy-saving mode is determined based on the target indication information or target configuration information.
[0073] The cell access status includes whether access is allowed or denied.
[0074] If the cell access status of the first cell is "Barred Cell", it means that the first cell is a Barred Cell for the terminal. If the cell access status of the first cell is "Allowed Cell", it means that the first cell is not a Barred Cell for the terminal. The terminal can change to an Acceptable Cell if it meets the cell selection criteria (such as the S criterion corresponding to cell camping).
[0075] It should be noted that the meaning of "allowed access" or "prohibited access" in the cell access status is different from that of "prohibited cell" in related technologies. In related technologies, the traditional prohibited cell is at the cell level, that is, the first cell prohibits access for all terminals. In this application, the cell access status is at the terminal level. For example, the cell access status of the first cell is allowed for terminal A that supports energy-saving technology, while it is prohibited for traditional terminal B.
[0076] In some embodiments, whether the first cell is in energy-saving mode is determined by the terminal based on at least one of the target configuration information, the synchronization signal of the first cell, and the system message of the first cell.
[0077] Understandably, the way a terminal determines whether a cell is in power-saving mode may change when the first cell is in power-saving mode. For example, in the 3rd Generation Partnership Project (3GPP) NES in R18, network-side equipment could indicate whether the corresponding cell was in power-saving mode via the cellBarredNES-r18 information cell in SIB1. However, in R19's OD-SIB1, because SIB1 is no longer transmitted according to the traditional periodic transmission method, the power-saving mode indication method in R18's NES is no longer applicable.
[0078] In some possible implementations, the terminal can determine whether the first cell is in energy-saving mode through the following steps.
[0079] In step 10, the first physical cell identifier (PCI) and the first cell frequency corresponding to the target configuration information are obtained.
[0080] For example, when obtaining target configuration information, the terminal can also obtain the first physical cell identifier (PCI) and the first cell frequency of the cell corresponding to the target configuration information.
[0081] The first physical cell identifier (PCI) and first cell frequency corresponding to the target configuration information can be the first physical cell identifier (PCI) and first cell frequency included in the target configuration information, or they can be the physical cell identifier (PCI) and cell frequency corresponding to the target configuration information in the predefined correspondence between configuration information, physical cell identifier (PCI), and cell frequency. The specific implementation scheme of the first physical cell identifier (PCI) and first cell frequency corresponding to the target configuration information in this application is not limited.
[0082] In step 20, the second physical cell identifier (PCI) and the second cell frequency are obtained through the synchronization signal of the first cell.
[0083] Taking 5G as an example, network-side equipment can obtain the synchronization signal and system messages of the first cell from the Non-Cell Definition Synchronization Signal Block (NCD-SSB). The synchronization signal includes the Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS), while the system messages can be the Master Indication Block (MIB) within the NCD-SSB. The terminal can obtain the second cell frequency of the first cell through the PSS and SSS, and subsequently, the second physical cell identifier (PCI). It is understood that the synchronization signal and system messages of the first cell are not necessarily sent to the terminal within the same synchronization signal block (e.g., the NCD-SSB in 5G); they can also be sent to the terminal through different signal blocks / messages.
[0084] In step 30, if the first physical cell identifier (PCI) and the second physical cell identifier (PCI) are the same, and the first cell frequency and the second cell frequency are the same, it is determined that the first cell is in energy-saving mode.
[0085] The terminal can determine that the first cell is in energy-saving mode if the second PCI and the second cell frequency are the same as the first PCI and the first cell frequency, respectively.
[0086] Of course, the technical solutions for the terminal to determine whether the first cell is in energy-saving mode are not limited to this. The terminal can also determine whether the first cell is in energy-saving mode in any of the following ways.
[0087] Method 1: The terminal can determine whether the first cell is in energy-saving mode based solely on the target configuration information.
[0088] In one possible implementation, the terminal can determine whether the first cell is in energy-saving mode based on whether the target configuration information includes any one of the following: wake-up signal UL WUS configuration, first system information block SIB1 reception configuration, and on-demand SIB1 request configuration.
[0089] In another possible implementation, the terminal can obtain target configuration information from the second cell and determine whether the first cell is in energy-saving mode based on the newly added indicator bits in the target configuration information.
[0090] Method 2: The terminal can determine whether the first cell is in energy-saving mode based solely on the system message from the first cell.
[0091] For example, a terminal can determine whether the first cell is in power-saving mode by adding an indicator bit to the MIB in the NCD-SSB.
[0092] The terminal can also determine that the first cell is in energy-saving mode if the subcarrier offset indication Kssb in the system message of the first cell indicates that the synchronization signal block SSB of the first cell is a non-cell-defined synchronization signal block NCD-SSB.
[0093] Method 3: The terminal can determine whether the first cell is in energy-saving mode based solely on the synchronization signal of the first cell.
[0094] For example, the terminal can obtain the second cell frequency of the first cell through the synchronization signals PSS and SSS, and then obtain the second physical cell identifier (PCI). Based on whether the second PCI is within a preset range and whether the second cell frequency is within a preset range, the terminal can determine whether the first cell is in energy-saving mode.
[0095] Method 4: The terminal can combine steps 29-30 above and Method 2 to determine whether the first cell is in energy-saving mode.
[0096] For example, a terminal can determine that the first cell is in power-saving mode if the second PCI and the second cell frequency are the same as the first PCI and the first cell frequency, respectively, and the subcarrier offset indication Kssb in the system message of the first cell indicates that the synchronization signal block SSB of the first cell is a non-cell defined synchronization signal block NCD-SSB.
[0097] Of course, the terminal can also determine whether the first cell is in energy-saving mode based on the implementation of steps 10-30 above and any combination of methods one to three above. For example, based on the premise that the first physical cell identifier (PCI) and the second physical cell identifier (PCI) are the same as determined in steps 10-30, and the first cell frequency and the second cell frequency are the same, it can further determine whether the first cell is in energy-saving mode if the newly added indicator bit in the system message indicates that the first cell is an energy-saving cell.
[0098] For example, the terminal can determine that the first cell is in power-saving mode when the first physical cell identifier (PCI) and the second physical cell identifier (PCI) are the same, the first cell frequency and the second cell frequency are the same, and the subcarrier offset indicator (Kssb) in the system message of the first cell indicates that the synchronization signal block (SSB) of the first cell is a non-cell defined synchronization signal block (NCD-SSB).
[0099] By adopting the above technical solution, the cell access status of the first cell in energy-saving mode can be determined according to the target indication information or the target configuration information. This allows terminals that support energy-saving technology to stay in the first cell in energy-saving mode without having to go through multiple reselections when the first cell changes from normal mode to energy-saving mode, which is beneficial to energy saving of terminals and network-side equipment.
[0100] Figure 3 shows another flowchart of the method for determining cell status provided in the embodiments of this disclosure. As shown in Figure 3, step S102 may include the following steps.
[0101] In step S1021, the cell access status of the first cell in energy-saving mode is determined to be allowed access if at least one of the following conditions is met:
[0102] The first system message includes target configuration information;
[0103] The second system message or short message includes the first instruction information;
[0104] The second system message or short message includes the second instruction information;
[0105] The third indication message indicates that SIB1 of the first cell has not been scheduled.
[0106] For example, if the terminal receives a first system message that includes at least one of the following: a wake-up signal UL WUS configuration, a first system information block SIB1 receive configuration, or an on-demand SIB1 request configuration, it can determine that the cell access state of the first cell in energy-saving mode is allowed access. Similarly, if the terminal receives a first system message from a second cell that includes at least one of the target configuration information stored in the terminal and still valid, such as a wake-up signal UL WUS configuration, a first system information block SIB1 receive configuration, or an on-demand SIB1 request configuration, it can determine that the cell access state of the first cell in energy-saving mode is allowed access.
[0107] For example, if the terminal receives a second system message that includes the first indication information, it can determine that the cell access status of the first cell in energy-saving mode is allowed access. The terminal can also determine that the cell access status of the first cell in energy-saving mode is allowed access if it receives an RRC message that includes the first indication information. The terminal can also determine that the cell access status of the first cell in energy-saving mode is allowed access if it receives a short message that includes the first indication information. Of course, the terminal can also determine that the cell access status of the first cell in energy-saving mode is allowed access if at least two or all of the second system message, RRC message, and short message include the first indication information.
[0108] For example, if the terminal receives a second system message that includes the second indication information, it can determine that the cell access status of the first cell in energy-saving mode is allowed access. The terminal can also determine that the cell access status of the first cell in energy-saving mode is allowed access if it receives an RRC message that includes the second indication information. The terminal can also determine that the cell access status of the first cell in energy-saving mode is allowed access if it receives a short message that includes the second indication information. Of course, the terminal can also determine that the cell access status of the first cell in energy-saving mode is allowed access if at least two or all of the second system message, RRC message, and short message include the second indication information.
[0109] For example, if the third indication information in the target indication information indicates that the SIB1 of the first cell has not been scheduled, the terminal can determine that the cell access status of the first cell in energy-saving mode is allowed access.
[0110] Understandably, the terminal can also determine the cell access status as allowed when the first cell is in energy-saving mode, provided that multiple of the above conditions are met simultaneously. This further improves the accuracy of cell status determination.
[0111] In some embodiments, if at least one of the following conditions is met—that the first system message or the RRC message includes the target configuration information or the third indication message indicates that the SIB1 of the first cell has not been scheduled—the terminal may also perform at least one of the following steps:
[0112] Determine the stored SIB1 as a valid SIB1 or the latest SIB1;
[0113] If the terminal has a stored SIB1, the stored SIB1 is determined to be a valid SIB1 or the latest SIB1;
[0114] If the terminal does not have SIB1 stored, execute an SIB1 request.
[0115] For example, a terminal camps on a first cell, obtains the OD-SIB1 request configuration information of the first cell, and stores the SIB1 of the first cell. The SSB sent by the first cell is CD-SSB, which indicates that the first cell has an SIB1 scheduled, meaning the first cell is in normal operating mode. When the first cell switches to power-saving mode, the sent SSB becomes NCD-SSB, which indicates that the first cell's SIB1 has not been scheduled. Since the terminal has the OD-SIB1 request configuration information of the first cell, the terminal can determine that the stored SIB1 is a valid SIB1 or the latest SIB1 and continue camping on the first cell. For other terminals that have not obtained the OD-SIB1 request configuration information of the first cell, the stored SIB1 is determined to be invalid, the stored SIB1 is deleted or released, and a cell selection or cell reselection procedure is executed.
[0116] If the terminal only has the OD-SIB1 request configuration information for the first cell, but no stored SIB1, the terminal can execute the SIB1 request to obtain the SIB1 of the first cell for entering energy-saving mode and camp on the first cell.
[0117] If the first cell does not send a short message to notify the system of the message change when it switches from normal working mode to energy saving mode, the terminal needs to obtain the SSB of the first cell to determine whether the latest SSB sent by the first cell is CD-SSB or NCD-SSB in order to execute the above scheme.
[0118] Figure 4 shows another flowchart of the method for determining cell status provided in the embodiments of this disclosure. As shown in Figure 4, step S102 may include the following steps.
[0119] The cell access status is determined to be prohibited when the first cell is in energy-saving mode if at least one of the following conditions is met:
[0120] The first system message does not include target configuration information;
[0121] The first instruction information is not included in the second system message or short message;
[0122] The second system message or short message does not include the second instruction information.
[0123] For example, if the terminal receives a first system message that does not include at least one of the following: wake-up signal UL WUS configuration, first system information block SIB1 receive configuration, or on-demand SIB1 request configuration, it can determine that the cell access state of the first cell in energy-saving mode is "access prohibited". Similarly, if the terminal receives a first system message from the first cell that does not include at least one of the following: wake-up signal UL WUS configuration, first system information block SIB1 receive configuration, or on-demand SIB1 request configuration, it can determine that the cell access state of the first cell in energy-saving mode is "access prohibited". The terminal can also determine that the cell access state of the first cell in energy-saving mode is "access prohibited" if it receives a first system message from the second cell, and the target configuration information stored in the terminal and still valid does not include at least one of the following: wake-up signal UL WUS configuration, first system information block SIB1 receive configuration, or on-demand SIB1 request configuration.
[0124] For example, if the terminal receives a second system message that does not include the first indication information, it can determine that the cell access status of the first cell in energy-saving mode is "access prohibited". Alternatively, if the terminal receives a short message that does not include the first indication information, it can determine that the cell access status of the first cell in energy-saving mode is "access allowed". Of course, the terminal can also determine that the cell access status of the first cell in energy-saving mode is "access prohibited" if neither the second system message nor the short message includes the first indication information.
[0125] For example, if the second system message does not include the second indication information, the terminal can determine that the cell access status of the first cell in energy-saving mode is "access prohibited". Alternatively, if the short message does not include the second indication information, the terminal can determine that the cell access status of the first cell in energy-saving mode is "access allowed". Of course, the terminal can also determine that the cell access status of the first cell in energy-saving mode is "access prohibited" if neither the second system message nor the short message includes the second indication information.
[0126] The terminal can also determine that the cell access status is prohibited when the first cell is in energy-saving mode, provided that multiple of the above three conditions are met simultaneously. This further improves the accuracy of cell status determination.
[0127] In some embodiments, when the terminal determines that the cell access status of the first cell is in energy-saving mode and is allowed to access, the terminal may configure to camp on the first cell based on the wake-up signal UL WUS in the target configuration information. When the terminal determines that the cell access status of the first cell is in energy-saving mode and is prohibited to access, the terminal may prohibit reselection to the first cell and reselect to other cells.
[0128] By adopting the above technical solution, the cell access status of the first cell in energy-saving mode can be determined according to the target indication information or target configuration information. This allows terminals that support energy-saving technology to stay in the first cell in energy-saving mode without having to go through multiple reselections when the first cell changes from normal mode to energy-saving mode, which is beneficial to energy saving of terminals and network-side equipment.
[0129] Figure 5 shows another flowchart of the method for determining cell status provided in the embodiments of this disclosure. As shown in Figure 5, step S102 may include the following steps.
[0130] In step S1023, when a short message including third indication information is received from the first cell, or when a first signal is received from the first cell, the cell access status when the first cell is in energy-saving mode is determined according to the target indication information or target configuration information.
[0131] The third indication information is used to indicate system message changes. For example, the third indication information can be the systemInfoModification bit in the short message, or it can be other newly defined bits. This application does not limit this. The first signal is a non-cell defined system message block NCD-SSB. The cell identifier associated with the wake-up signal UL WUS configuration is the same as the cell identifier corresponding to the first signal.
[0132] In some embodiments, the terminal may determine that the first cell may be changing between normal mode and energy-saving mode based on receiving a short message including third indication information from the first cell, or receiving a first signal from the first cell, thereby initiating the step of determining the cell access state when the first cell is in energy-saving mode according to the target indication information or target configuration information.
[0133] By adopting the above technical solution, the method for determining the cell status can be executed when it is determined that the energy-saving mode of the first cell may change, thereby further improving the pertinence of the method for determining the cell status and further improving the energy-saving effect of the terminal.
[0134] In another embodiment, when determining the cell access status of the first cell in energy-saving mode based on whether the first system message includes target configuration information, a further step can be taken after receiving the first signal to determine the cell access status of the first cell in energy-saving mode based on whether the cell identifier associated with the target configuration information is the same as the cell identifier corresponding to the first signal.
[0135] For example, if the terminal receives a first system message that includes target configuration information, and the cell identifier associated with the target configuration information is the same as the cell identifier corresponding to the first signal, the terminal can determine that the cell access status of the first cell in energy-saving mode is "access allowed". Alternatively, if the terminal receives a first system message that includes target configuration information, but the cell identifier associated with the target configuration information is different from the cell identifier corresponding to the first signal, the terminal can determine that the cell access status of the first cell in energy-saving mode is "access prohibited".
[0136] By adopting the above technical solution, when determining the cell status, it is possible to consider whether the cell identifier associated with the target configuration information is the same as the cell identifier corresponding to the first signal, thereby further improving the accuracy and flexibility of the method for determining the cell status and adapting to more application scenarios.
[0137] Figure 6 shows another flowchart of the method for determining cell status provided in the embodiments of this disclosure. As shown in Figure 6, step S102 may include the following steps.
[0138] In step S1024, the first system information block SIB1 is received according to any one of the following: If the first system information block SIB1 is received, the cell access state when the first cell is in energy-saving mode is determined according to the first system information block SIB1:
[0139] First system information block SIB1 receives configuration;
[0140] The first system information block SIB1 received configuration is included in the first signal;
[0141] The first system information block SIB1 receiving configuration and the first system information block SIB1 receiving configuration included in the first signal;
[0142] The wake-up signal UL WUS configuration includes the first system information block SIB1 receive configuration;
[0143] The valid wake-up signal WUS configuration stored in the energy-saving terminal includes the first system information block SIB1 receiving configuration.
[0144] The first system information block SIB1 receiving configuration is used by the terminal to receive SIB1 when the first cell is in energy-saving mode.
[0145] For example, the first system information block SIB1 reception configuration may be the PDCCH (Physical Downlink Control Channel) configuration information for receiving SIB1.
[0146] The configuration for receiving the first system information block SIB1 may include at least one of the following:
[0147] PDCCH Configuration: Instructs the terminal to receive the PDCCH configuration of SIB1;
[0148] SIB1 transmission cycle;
[0149] Receive window: Indicates the time domain window through which the terminal receives SIB1;
[0150] Time domain start point: Indicates the time domain start point for the terminal to receive SIB1;
[0151] Time domain endpoint: Indicates the time domain endpoint at which the terminal receives SIB1;
[0152] Time-domain offset: indicates the time-domain offset between the time-domain start point of the terminal receiving SIB1 and the start point of the second short message, or indicates the time-domain offset between the time-domain start point of the terminal receiving SIB1 and the end point of the second short message; the unit of offset can be any of the following: symbol, mini-slot, slot, subframe, or frame.
[0153] It is understood that the above-mentioned first system information block SIB1 receiving configuration is different from the PDCCH-ConfigSIB1 carried in the MIB in related technologies. In some embodiments, when the first cell is in energy-saving mode, the PDCCH-ConfigSIB1 sent in the MIB information can be set to a special preset value.
[0154] In some embodiments, the first system information block SIB1 receiving configuration may be carried in the target configuration information, and the terminal may receive SIB1 based on the first system information block SIB1 receiving configuration in the target configuration information.
[0155] In another embodiment, the terminal may also receive a first signal, wherein the first signal is a non-cell defined system message block (NCD-SSB). In the prior art, PDCCH_ConfigSIB1 in NCD-SSB actually indicates the frequency point information that can receive SIB1, which is completely different from PDCCH_ConfigSIB1 in CD-SSB, which actually indicates the PDCCH information of CORESET#0 (i.e., the normal SIB1 reception configuration). In this application, although the subcarrier offset Kssb indicated by the first signal indicates that the signal transmitted by the first cell is NCD-SSB, the terminal can receive SIB1 through the first system information block SIB1 in the payload of the Physical Broadcast Channel (PBCH) in the first signal. That is, by carrying the SIB1 reception configuration in the NCD-SSB, the terminal supporting energy-saving technology can receive SIB1 according to the SIB1 reception configuration in the NCD-SSB. The specific information cell corresponding to the SIB1 reception configuration can reuse PDCCH_ConfigSIB1 (with appropriate modification of the existing information cell), or a new information cell can be used, such as PDCCH_ConfigSIB1_WES. This application does not limit this.
[0156] In another embodiment, the terminal can also receive the first system information block SIB1 according to the first system information block SIB1 reception configuration and the first system information block SIB1 reception configuration included in the first signal. Similar to the previous embodiment, although the subcarrier offset Kssb indicated by the first signal indicates that the signal transmitted by the first cell is NCD-SSB, the terminal can receive SIB1 through the first system information block SIB1 reception configuration in the payload Pay Load in the PBCH of the first signal. The terminal can determine the window for SIB1 reception and the SIB1 transmission period through the wake-up signal UL WUS configuration or the first system information block SIB1 reception configuration in the target configuration information.
[0157] In some embodiments, the first system information block SIB1 receiving configuration may be carried in the wake-up signal UL WUS configuration in the target configuration information, and the terminal may receive SIB1 based on the first system information block SIB1 receiving configuration in the wake-up signal UL WUS configuration. In some possible implementations, the cell identifier associated with the wake-up signal UL WUS configuration may be the same as the cell identifier indicated by the first signal; that is, if the cell identifier associated with the wake-up signal UL WUS configuration is the same as the cell identifier indicated by the first signal, SIB1 is received based on the first system information block SIB1 receiving configuration in the wake-up signal UL WUS configuration.
[0158] In some embodiments, the terminal can receive SIB1 based on the first system information block SIB1 in the stored valid wake-up signal UL WUS configuration. In some possible implementations, the cell identifier associated with the stored valid wake-up signal UL WUS configuration may be the same as the cell identifier indicated by the first signal; that is, if the cell identifier of the stored valid wake-up signal UL WUS configuration is the same as the cell identifier indicated by the first signal, the terminal receives SIB1 based on the first system information block SIB1 in the wake-up signal UL WUS configuration.
[0159] Figure 7 shows another flowchart of the method for determining cell status provided in the embodiments of this disclosure. As shown in Figure 7, step S102 may further include the following steps.
[0160] In step S1025, a first signal is received from the first cell.
[0161] In this context, the subcarrier offset indicator Kssb in the first signal is a preset value, and the first signal is a non-cell defined system message block (NCD-SSB).
[0162] In some embodiments, if the subcarrier offset indicator Kssb in the first signal (NCD-SSB) is a preset value, the terminal can receive SIB1 through the first system information block SIB1 receiving configuration in the payload Pay Load in the first signal. If the subcarrier offset Kssb indicated by the first signal (NCD-SSB) is not a preset value, the terminal can receive SIB1 in other ways than the first system information block SIB1 receiving configuration included in the first signal in step S1024.
[0163] In some embodiments, the terminal may also receive the first system information block SIB1 if at least one of the following conditions is met:
[0164] The second system message or short message includes the first instruction information;
[0165] The second system message or short message includes the second instruction information;
[0166] A short message containing a third indication message was received from the first cell. The third indication message is a system message change indication message.
[0167] By adopting the above technical solution, the cell access status of the first cell in energy-saving mode can be determined according to the target indication information or the target configuration information. This allows the terminal supporting energy-saving technology to stay in the first cell in energy-saving mode without having to perform multiple reselections or send OD-SIB1 request messages to the first cell when the first cell changes from normal mode to energy-saving mode. This is beneficial for energy saving of terminal and network side equipment.
[0168] Figure 8 shows another flowchart of the method for determining cell status provided in the embodiments of this disclosure. As shown in Figure 8, the method may further include the following steps.
[0169] In step S103, a second signal or a third signal is received from the first cell.
[0170] The second signal is the Non-Cell Defined System Message Block (NCD-SSB), and the third signal is the Cell Defined System Message Block (CD-SSB).
[0171] In some embodiments, upon receiving a third signal from the first cell, the terminal can obtain target indication information or target configuration information, and upon receiving a short message including the third indication information from the first cell, or upon receiving a first signal from the first cell, determine the cell access status of the first cell in energy-saving mode based on the target indication information or the target configuration information. In some optional implementations, the cell identifier corresponding to the third signal is different from the cell identifier corresponding to the first signal; that is, the network-side device can use a different cell identifier (PCI) than in normal mode when entering energy-saving mode, thereby improving the convenience for the terminal to determine the cell access status of the first cell in energy-saving mode.
[0172] In some embodiments, the terminal may obtain target indication information or target configuration information when it receives a second signal from the first cell, and determine the cell access status when the first cell is in energy-saving mode based on the target indication information or the target configuration information when it receives a short message including third indication information from the first cell or receives a first signal from the first cell.
[0173] By adopting the above technical solution, the cell access status of the first cell in energy-saving mode can be determined according to the target indication information or the target configuration information. This allows terminals that support energy-saving technology to stay in the first cell in energy-saving mode without having to go through multiple reselections when the first cell changes from normal mode to energy-saving mode, which is beneficial to energy saving of terminals and network-side equipment.
[0174] Figure 9 shows a flowchart of a method for determining cell status provided in an embodiment of this disclosure. The method is applied to a network-side device. As shown in Figure 9, the method may include the following steps.
[0175] In step S201, target indication information or target configuration information is sent from the first cell or the second cell to the terminal.
[0176] The target indication information or target configuration information is used by the terminal to determine the cell access status when the first cell is in energy-saving mode. The cell access status includes allowing access or prohibiting access. Whether the first cell is in energy-saving mode is determined by the terminal based on at least one of the target configuration information, the synchronization signal of the first cell, and the system message of the first cell.
[0177] In some embodiments, the target configuration information is sent by the network-side device in a first system message of the first cell or the second cell, and the target indication information is sent by the network-side device in a second system message or short message of the first cell.
[0178] Target indication information includes at least one of the following:
[0179] The first indication information is used to indicate that the terminal is allowed to access the first cell when it is in energy-saving mode.
[0180] The second indication information is used to indicate the target configuration information in the system message of the first cell;
[0181] The third indication information is used to indicate whether SIB1 of the first cell has been scheduled.
[0182] The target configuration information includes at least one of the following:
[0183] Wake-up signal UL WUS configuration;
[0184] First system information block SIB1 receives configuration;
[0185] SIB1 configuration requests are made on demand;
[0186] The terminal is a terminal that supports at least one of the following features:
[0187] Network energy-saving NES;
[0188] Request OD-SIB1 on demand;
[0189] Request OD-SSB from the on-demand synchronization signal block SSB;
[0190] On-demand tracking of reference signal TRS requests OD-TRS;
[0191] Discontinuous transmission of DTX in the cell;
[0192] Discontinuous reception DRX in the cell;
[0193] NES-based conditional switching;
[0194] Random access adaptive RACH adaptation;
[0195] Paging adaptation;
[0196] SSB adaptation;
[0197] The first system information block SIB1 receiving configuration is used by the terminal to receive SIB1 when the first cell is in energy-saving mode.
[0198] By adopting the above technical solution, target indication information or target configuration information can be sent to the terminal, so that the terminal can determine the cell access status when the first cell is in energy-saving mode according to the target indication information or target configuration information. Thus, when the first cell changes from normal mode to energy-saving mode, the terminal supporting energy-saving technology can stay in the first cell in energy-saving mode without having to go through multiple reselections, which is beneficial to energy saving of terminal and network side equipment.
[0199] In some embodiments, a first signal is sent after the target indication information or target configuration information. The first signal is a Non-Cell Defined Synchronization Signal Block (NCD-SSB). In another embodiment, a second signal or a third signal is sent before the target indication information or target configuration information. The second signal is a NCD-SSB, and the third signal is a Cell Defined Synchronization Signal Block (CD-SSB). The cell identifier corresponding to the third signal is different from the cell identifier corresponding to the first signal.
[0200] In another embodiment, the subcarrier offset in the second signal is indicated by a preset value.
[0201] The above technical solution is a technical solution for the network-side device corresponding to the first aspect embodiment. Through the collaboration between the network-side device and the terminal, the terminal can execute the technical solution of the first aspect embodiment, thereby achieving the corresponding technical effect. For details, please refer to the description of the first aspect embodiment, which will not be elaborated here.
[0202] Figure 10 shows a flowchart of a method for determining cell status provided in an embodiment of the present disclosure. As shown in Figure 10, the method may include the following steps.
[0203] In step S301, the network-side device sends a second signal or a third signal to the terminal.
[0204] The second signal is the non-cell defined synchronization signal block NCD-SSB.
[0205] In step S302, the network-side device sends target indication information or target configuration information to the terminal.
[0206] In step S303, the network-side device sends a first signal to the terminal.
[0207] The first signal is a non-cell-defined synchronization signal block (NCD-SSB), and the third signal is a cell-defined synchronization signal block (CD-SSB). The cell identifier corresponding to the third signal is different from the cell identifier corresponding to the first signal.
[0208] In step S304-1, the terminal determines the cell access status when the first cell is in energy-saving mode based on the target indication information or target configuration information.
[0209] In step S304-2, the terminal receives the first system information block SIB1 according to the target indication information or target configuration information. Upon receiving the first system information block SIB1, the terminal determines the cell access status of the first cell in energy-saving mode based on the first system information block SIB1.
[0210] The terminal can choose to execute either step S304-1 or step S304-2, or execute both steps in any order, thereby further improving the accuracy of determining the cell status.
[0211] Using the above technical solution, the network-side equipment can send target indication information or target configuration information to the terminal. The terminal can determine the cell access status when the first cell is in energy-saving mode based on the target indication information or target configuration information. This allows the terminal that supports energy-saving technology to stay in the first cell in energy-saving mode without having to go through multiple reselections when the first cell changes from normal mode to energy-saving mode, which is beneficial to energy saving for both the terminal and the network-side equipment.
[0212] The method for determining cell status provided in this application can be executed by a device for determining cell status. This application uses an example of a device for determining cell status executing the method to illustrate the device for determining cell status provided in this application.
