AI Technical Summary
When the terminal cannot obtain candidate cell information, the existing technology directly determines the cell to be in a banned state, resulting in cells with acceptable signal quality not being selected as camping points, causing a waste of wireless resources.
The terminal assesses the reasons why information cannot be obtained, distinguishes whether the cell status is blocked or not, avoids misjudging cells with poor signal quality, and uses network device indication information or the terminal's own conditions to determine the cell status.
This avoids wasting wireless resources due to misjudging cell status and improves network resource utilization efficiency.

Background Technology
[0002] Terminals can perform cell selection and cell reselection operations in the communication system in order to camp on a suitable cell and thus ensure relatively good communication quality.
[0003] During the process of cell selection and cell reselection among candidate cells, the terminal attempts to receive some information from the candidate cells. If the terminal fails to obtain certain information from the candidate cells, it will exclude those candidate cells from the cell selection and reselection process. Several technical issues exist in this process that urgently need to be addressed. Summary of the Invention
[0004] Embodiments of this disclosure provide methods and apparatus for determining and indicating states, communication systems, and storage media to address technical problems in the related art.
[0005] According to a first aspect of the present disclosure, a state determination method is proposed, executed by a terminal, the method comprising: determining the state of the first cell in response to the inability to obtain first information of the first cell, wherein the state of the first cell includes: the first cell being in a blocked state; or the first cell being in an unblocked state.
[0006] According to a second aspect of the present disclosure, a status indication method is provided, executed by a network device, the method comprising: sending first indication information to a terminal, wherein the first indication information is used to determine the status of the first cell when the terminal is unable to obtain first information of the first cell, wherein the status of the first cell includes: the first cell being in a blocked state; or the first cell being in an unblocked state.
[0007] According to a third aspect of the present disclosure, a state determination apparatus is provided, the apparatus comprising: a processing module configured to determine the state of the first cell in response to the inability to obtain first information of the first cell, wherein the state of the first cell includes: the first cell being in a blocked state; or the first cell being in an unblocked state.
[0008] According to a fourth aspect of the present disclosure, a status indication device is provided, the device comprising: a sending module configured to send first indication information to a terminal, wherein the first indication information is used by the terminal to determine the status of the first cell in response to the inability to obtain first information of the first cell, wherein the status of the first cell includes: the first cell being in a blocked state; or the first cell being in an unblocked state.
[0009] According to a fifth aspect of the present disclosure, a terminal is provided, comprising: one or more processors; wherein the terminal is configured to execute the state determination method described in the first aspect.
[0010] According to a sixth aspect of the present disclosure, a network device is provided, comprising: one or more processors; wherein the network device is configured to perform the status indication method described in the second aspect.
[0011] According to a seventh aspect of the present disclosure, a communication system is provided, including a terminal and a network device, wherein the terminal is configured to implement the state determination method described in the first aspect, and the network device is configured to implement the state indication method described in the second aspect.
[0012] According to an eighth aspect of the present disclosure, a storage medium is provided that stores instructions, which, when executed on a communication device, cause the communication device to perform the state determination method described in the first aspect and / or the state indication method described in the second aspect.
[0013] According to a ninth aspect of the present disclosure, a computer program is provided that, when run on a computer, causes the computer to perform the state determination method described in the first aspect and / or the state indication method described in the second aspect.
[0014] If a terminal attempts to obtain first information in the first cell but fails to do so, it can be determined that the first information of the first cell cannot be obtained. In this case, according to the embodiments of this disclosure, instead of directly determining the first cell as being in a blocked state, the state of the first cell can be evaluated to further determine whether the first cell is in a blocked state or not.
[0015] Therefore, it is beneficial to avoid the situation where the first cell is designated as disabled when the first information is in an on-demand state, rather than when the signal quality of the first cell is too poor for the terminal, resulting in few terminals camping on the first cell and wasting wireless resources in the network.

[0096] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).
[0097] In some embodiments, the terminal may perform cell selection, cell reselection, and other operations in the candidate cells of the communication system in order to determine the appropriate cell to camp on.
[0098] In some embodiments, the primary objective of cell selection is for the terminal to select a cell with satisfactory signal quality for camping as quickly as possible within the chosen PLMN (Public Land Mobile Network). The terminal determines whether the cell selection criteria are met based on measured cell signal strength (e.g., Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ)) and relevant parameters, which can be configured based on System Information Block (SIB) 1.
[0099] In some embodiments, the primary purpose of cell reselection is to help a terminal camp on a cell with better signal quality and higher priority. A UE that can perform cell reselection must at least meet the following conditions:
[0100] The terminal is in a disconnected state:
[0101] The terminal has already camped on a cell (e.g., completed the cell selection process).
[0102] UEs that meet the above conditions can select more suitable cells by continuously performing cell quality detection and / or measurement.
[0103] In some embodiments, when a terminal performs cell selection or cell reselection among candidate cells, it can receive first information from the candidate cells, such as System Information Block (SIB) 1. When the terminal cannot receive the first information in the first cell among the candidate cells, it will determine that the first cell is in a barred state, that is, the first cell will be excluded from the candidate cells for a period of time (e.g., 300 seconds). During this period, when the terminal performs cell selection or cell reselection, it will not consider the first cell as a candidate cell, and therefore will not select or reselect to the first cell.
[0104] However, there are many reasons why a terminal may fail to receive the first information in the first cell. For example, the signal quality in the first cell may be too poor for the terminal, so although the network device sends the first information in the first cell, the terminal cannot receive it. Alternatively, the network device may be about to enter Network Energy Saving (NSE) mode, or may already be in NES mode. In this case, the first information in the first cell may be in an on-demand state, meaning the network device stops sending the first information in the first cell. When the terminal needs to obtain the first information, it can send a request to the network device, and the network device, upon receiving the request, can then choose to send the first information in the first cell.
[0105] It is evident that the terminal's inability to receive the first information in the first cell may not be due to poor signal quality in the first cell for the terminal. It may simply be that the first information is in an on-demand state in the first cell, rather than because the signal quality in the first cell is poor for the terminal.
[0106] In this situation, it is inaccurate to directly determine that the first cell is blocked if the terminal cannot receive the first information in the first cell. For example, for a specific first cell, the signal quality of the first cell may be acceptable for the terminal, but the first information in the first cell is in an on-demand state, causing the terminal to determine that the first cell is blocked and no longer try to camp in the first cell, resulting in few terminals camping in the first cell and wasting the wireless resources in the network.
[0107] Figure 2 This is an interactive schematic diagram illustrating a state determination method according to an embodiment of the present disclosure.
[0108] like Figure 2 As shown, the state determination method may include the following steps:
[0109] In step S201, the terminal attempts to obtain the first information of the first cell.
[0110] In some embodiments, the terminal may attempt to obtain first information about the first cell based on a first condition. That is, if the first condition is met, the terminal may attempt to obtain the first information about the first cell.
[0111] In some embodiments, the first condition may include at least one of the following:
[0112] The terminal is in a disconnected state, which includes at least one of the following: idle state and inactive state;
[0113] The terminal obtains indication information for indicating the transmission of the first information in the first cell. For example, the indication information may include an information element (IE) ssb-SubcarrierOffset (e.g., which can be translated as synchronization broadcast signal block subcarrier offset).
[0114] The terminal sends a request message to the network device, wherein the request message is used to request the network device to send first information;
[0115] The terminal is in a connected state and has received a system information change instruction;
[0116] The terminal is in a connected state, and the T311 timer (the specific meaning of which can be found in relevant technologies, and will not be elaborated here) is running;
[0117] The terminal is in a connected state and has failed to obtain a valid version of the system information, or has not obtained valid system information (e.g., SIB1) during the current modification.
[0118] For example, in some embodiments, when the terminal is in a disconnected state, the terminal may attempt to obtain the first information of the first cell.
[0119] In some embodiments, when a terminal obtains indication information for indicating the transmission of first information in a first cell, the terminal may attempt to obtain the first information of the first cell.
[0120] In some embodiments, when a terminal sends a request message to a network device to request the network device to send first information to the terminal, the terminal may attempt to obtain the first information of the first cell. In some embodiments, when the terminal is in a connected state and receives a system information change indication, the terminal may attempt to obtain the first information of the first cell.
[0121] In some embodiments, when the terminal is in a connected state and the T311 timer is running, the terminal may attempt to acquire the first information of the first cell. The activation and operation mechanism of the T311 timer has been described in detail in related technologies and will not be repeated here.
[0122] In some embodiments, when the terminal is in a connected state and fails to obtain a valid version of the system information, or fails to obtain valid system information during the current modification, the terminal may attempt to obtain the first information of the first cell.
[0123] In step S201, the terminal attempts to obtain the first information of the first cell. In some embodiments, the terminal successfully obtains the first information of the first cell, while in other embodiments, the terminal fails to obtain the first information of the first cell.
[0124] In step S202, in response to the terminal's inability to obtain the first information of the first cell, the terminal determines the state of the first cell, wherein the state of the first cell includes:
[0125] The first community is in a barred state; or
[0126] The first residential area is in a "not barred" state.
[0127] The terminal attempts to acquire first information about a first cell and determines the state of the first cell based on the acquisition result. In some embodiments, the terminal determines that it has acquired the first information about the first cell, and can then perform cell selection / reselection or cell camping based on the first information for the first cell.
[0128] In some embodiments, the terminal determines that it cannot obtain the first information. This determination can be based on the terminal's own implementation or on a predefined method. In short, the terminal determines that the acquisition of the first information was unsuccessful.
[0129] For example, if a terminal determines that it cannot obtain the first information based on its own implementation, it may include the terminal attempting to obtain the first information based on a first condition, and attempting to obtain the first information once or multiple times during the transmission cycle of the first information, but failing to obtain the first information, and the terminal determining that it cannot obtain the first information in the first cell.
[0130] For example, if a terminal determines that it cannot obtain the first information based on a predefined method, the predefined rule may include the terminal attempting to obtain the first information based on a first condition, and attempting to obtain the first information in n transmission cycles of the first information (n is an integer greater than or equal to 1, which can be agreed upon by the protocol, indicated by the network, or determined based on the terminal's capabilities), and the terminal determines that it cannot obtain the first information in the first cell.
[0131] In some embodiments, if a terminal attempts to obtain first information in a first cell but fails to obtain the first information, it can be determined that the first information of the first cell cannot be obtained. In this case, according to embodiments of this disclosure, instead of directly determining the first cell as being in a blocked state, it can further determine whether the first cell is in a blocked state or not. That is, if the terminal fails to obtain the first information, the terminal will not directly determine that the first cell is in a blocked state, but a subsequent determination mechanism will verify the state of the first cell. This is to avoid mistakenly determining that a first cell that is not blocked is in a blocked state.
[0132] Therefore, it is beneficial to avoid the situation where the first cell is designated as disabled when the first information is in an on-demand state, rather than when the signal quality of the first cell is too poor for the terminal, resulting in few terminals camping on the first cell and wasting wireless resources in the network.
[0133] In some embodiments, the first information includes at least one of the following:
[0134] System Information Block SIB1;
[0135] Synchronization Signal and Physical Downlink Broadcast Channel (SSB) Block.
[0136] It should be noted that the first information is not limited to SSB and SIB1 mentioned above, but may also include other information, such as Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), and other newly defined signals, such as signals composed of primary synchronization signal and secondary synchronization signal, Discovery Reference Signal (DRS), etc.
[0137] In some embodiments, when a terminal determines that a first cell is blocked, it may exclude the first cell from the candidate cells for cell selection or cell reselection for a period of time (e.g., 300 seconds). This period may be agreed upon by the protocol, indicated by the network device, or determined based on the terminal's capabilities. During this period, the terminal performs cell selection or cell reselection without considering the first cell.
[0138] In some embodiments, when a terminal determines that the first cell is not in a blocked state, if the first terminal can obtain the first configuration information, it can send a request message to the network device according to the first configuration to request the network device to send the first information. And / or, when a terminal determines that the first cell is not in a blocked state, it can identify the first cell as a candidate cell for cell selection and cell reselection, so that the first cell can be considered when performing cell selection and cell reselection.
[0139] For example, a network device can be requested to send the first information in a first cell, or it can be requested to send the first information in another cell. When another cell is not a cell under the network device of the first cell, the network device of the first cell can forward the request information to the network device of the other cell, thereby requesting the network device of the other cell to send the first information in that other cell.
[0140] It should be noted that the first configuration information used to send request information may be the same or different under different network devices and / or in different cells, and this disclosure does not limit this.
[0141] The following examples illustrate how a terminal can determine the status of a first cell when it is unable to obtain the first information of the first cell.
[0142] In some embodiments, determining the state of the first cell includes at least one of the following:
[0143] The status of the first cell is determined based on the first instruction information from the network device;
[0144] The status of the first cell is determined based on whether the terminal obtains the first configuration information. For example, the first configuration information can be used by the terminal to send request information to the network device, and the request information is used to request the network device to send the first information.
[0145] The status of the first cell is determined based on its type.
[0146] It should be noted that the methods for determining the status of the first cell are not limited to the above-mentioned methods, and this disclosure does not restrict them.
[0147] For example, when a terminal cannot obtain the first information of the first cell, it can send a request message to the network device according to the first configuration information to request the network device to send the first information in the first cell. Then, the terminal can determine the state of the first cell based on whether it can receive the first information in the first cell after sending the request message. For example, if the first information cannot be received in the first cell after sending the request message, it can be determined that the first cell is in a blocked state; if the first information can be received in the first cell after sending the request message, it can be determined that the first cell is not blocked, and the previous inability to obtain the first information was not due to the first cell being blocked, but due to other reasons.
[0148] In some embodiments, the first indication information includes at least one of the following:
[0149] Master Information Block (MIB);
[0150] Physical Broadcast Channel (PBCH);
[0151] Scrambling sequences for physical broadcast channels.
[0152] In some embodiments, the spare bits in the MIB can be used as the first indication information.
[0153] In some embodiments, the reserved bits in the PBCH can be used as the first indication information.
[0154] For example, the reserved bits in the PBCH can include bits from the PBCH. and / or For example, when communicating in the FR1 band, the reserved bits in the PBCH can include... and Bit.
[0155] In some embodiments, determining the state of the first cell includes at least one of the following:
[0156] In response to terminal communication in the first frequency domain range FR1, the status of the first cell in the physical broadcast channel is determined.
[0157] In response to terminal communication in the second frequency domain range FR2, the state of the first cell is determined based on the main information block;
[0158] In response to the terminal communicating in the second frequency domain range FR2, the state of the first cell is determined based on the scrambling sequence of the physical broadcast channel.
[0159] For example, the first frequency domain range may include the FR1 band, and the second frequency domain range may include the FR2 band.
[0160] It should be noted that, in scenarios involving communication in the first frequency domain and communication in the second frequency domain, determining the state of the first cell is not limited to the methods shown in the above embodiments, and this disclosure does not impose any limitations on this. For example, in communication in the first frequency domain, the state of the first cell can also be determined based on the MIB, or based on the scrambling sequence of the PBCH; similarly, in communication in the second frequency domain, the state of the first cell can also be determined based on the PBCH.
[0161] In some embodiments, for example, when the first indication information indicates a first value, the terminal can determine that the state of the first cell is in a blocked state; for example, when the first indication information indicates a second value, the terminal can determine that the state of the first cell is in an unblocked state.
[0162] In some embodiments, determining the state of the first cell based on the scrambling sequence of the physical broadcast channel includes at least one of the following:
[0163] The state of the first cell is determined based on the relevant parameters of the scrambling sequence of the physical broadcast channel;
[0164] The state of the first cell is determined based on the initial value of the scrambling sequence of the physical broadcast channel.
[0165] In some embodiments, the relevant parameters of the PBCH scrambling sequence may include, for example, the v value of the PBCH scrambling sequence (the specific meaning of which can be found in related technologies, and will not be elaborated here). It should be noted that the relevant parameters of the PBCH scrambling sequence are not limited to the v value; for example, they may also be the length of the PBCH scrambling sequence, and this disclosure does not limit this.
[0166] Taking the relevant parameters of the PBCH scrambling sequence, including the v value of the PBCH scrambling sequence, as an example.
[0167] For example, the terminal can determine whether the value v belongs to the first set of values. If the value v belongs to the first set of values, it can determine that the first cell is in a blocked state; if the value v does not belong to the first set of values, it can determine that the first cell is in a not blocked state.
[0168] For example, the terminal can determine the set of values to which the v value belongs. If the v value belongs to the first set of values, it can be determined that the first cell is in a blocked state; if the v value belongs to the second set of values, it can be determined that the first cell is in a not blocked state.
[0169] In some embodiments, the relevant parameters are determined based on at least one of the following:
[0170] Bits in the System Frame Number (SFN);
[0171] Half-frame indicator bits.
[0172] For example, the value of v can be determined based on the second least significant bit (LSB) and the third LSB in the SFN, where the second and third LSBs can be represented as in the SFN. and Bits. The correspondence between the value x of the second LSB and the value y of the third LSB and the value v can be shown in Table 1 below:
[0173] (x,y) v value (0,0) 0 (0,1) 1 (1,0) 2 (1,1) 3
[0174] Table 1
[0175] For example, the terminal determines the state of the first cell based on the set of values to which the value v belongs. For instance, if the first set of values is {0,1} and the second set of values is {2,3}, when the terminal determines that the value v is 2, it can determine that the value v belongs to the second set of values, and thus determine that the first cell is in an unblocked state.
[0176] For example, the v value can be determined based on the half-frame indicator bit, and the second and third LSBs in the SFN, where the half-frame indicator bit can be represented as the SFN... Bits. The correspondence between the half-frame indicator bit value z, the second LSB value x, and the third LSB value y, and the v value can be shown in Table 2 below:
[0177] (z,x,y) v value (0,0,0) 0 (0,0,1) 1 (0,1,0) 2 (0,1,1) 3 (1,0,0) 4 (1,0,1) 5 (1,1,0) 6 (1,1,1) 7
[0178] Table 2
[0179] For example, the terminal determines the state of the first cell based on the set of values to which the value v belongs. For example, the first set of values is {0,1,2,3}, and the second set of values is {4,5,6,7}. When the terminal determines that the value v is 5, it can determine that the value v belongs to the second set of values, and thus determine that the first cell is in an unblocked state.
[0180] In some embodiments, the terminal can determine the state of the first cell based on the initial value of the scrambling code sequence of the PBCH.
[0181] For example, in the first m-sequence corresponding to the scrambling sequence of PBCH (the specific meaning can be found in the relevant technology, and the meaning will not be elaborated here), if the initial value of x1(n) is determined based on the first method, the terminal can determine that the first cell is in a blocked state; if the initial value of x1(n) is determined based on the second method, the terminal can determine that the first cell is in an unblocked state.
[0182] For example, the first approach may include: x1(0) = 1, x1(n) = 0, n = 0, 1, 2, ..., 30.
[0183] For example, the second approach may include: x1(1) = 1, x1(n) = 0, n = 0, 2, 3, ..., 30.
[0184] In some embodiments, determining the state of the first cell based on whether the terminal has obtained the first configuration information includes at least one of the following:
[0185] In response to the terminal obtaining the first configuration information, it is determined that the first cell is in an unblocked state;
[0186] In response to the terminal's failure to obtain the first configuration information, it is determined that the first cell is in a disabled state;
[0187] In response to the terminal failing to obtain the first configuration information, it is determined that the first cell is in a blocked state for a first period of time. In response to the terminal obtaining the first configuration information for a first period of time, it is determined that the state of the first cell changes to an unblocked state.
[0188] In some embodiments, the first configuration information can be used by the terminal to send request information to the network device to request the network device to send first information.
[0189] The request information can request the network device to send the first information in the first cell, or it can request the network device to send the first information in other cells. When other cells are not under the network device of the first cell, the network device of the first cell can forward the request information to the network devices of other cells, thereby requesting the network devices of other cells to send the first information in those other cells.
[0190] It should be noted that the first configuration information used to send request information may be the same or different under different network devices and / or in different cells, and this disclosure does not limit this.
[0191] In some embodiments, when a terminal obtains the first configuration information, it can determine that the first cell is in an unblocked state. In this case, the terminal can choose to send request information in the first cell according to the first configuration information to request the network device to send first information in the first cell; the terminal can also determine that the first cell is a candidate cell for cell selection and cell reselection, so that when performing cell selection and cell reselection, it can determine whether it is necessary to select or reselect to the first cell, without ignoring the first cell.
[0192] In some embodiments, if the terminal fails to obtain the first configuration information, it can determine that the first cell is in a blocked state. In this case, the terminal can exclude the first cell from the candidate cells for cell selection and cell reselection for a period of time (e.g., 300 seconds). This period can be referred to as the first duration, which can be agreed upon by the protocol, indicated by the network device, or determined based on the terminal's capabilities. During the first duration, the terminal performs cell selection or cell reselection without considering the first cell.
[0193] It should be noted that, in the embodiments of this disclosure, if the terminal fails to obtain the first configuration information, it may include receiving the first configuration information based on the receiving period of the first configuration information. If the first configuration information is not received in one period, or if the first configuration information is not received in multiple periods of a period number threshold, it can be determined that the first configuration information has not been received.
[0194] In some embodiments, if the terminal fails to obtain the first configuration information, it may determine that the first cell is in a blocked state and exclude the first cell from the candidate cells for cell selection and cell reselection for a period of time, such as this period of time may be referred to as the first duration.
[0195] Within the first time period, the terminal may continue to attempt to obtain the first configuration information. If the terminal still fails to obtain the first configuration information within the first time period, the first cell remains in a blocked state; if the terminal obtains the first configuration information within the first time period, it can determine that the state of the first cell has changed to an unblocked state, and thus it can determine that the first cell belongs to the candidate cells for cell selection and cell reselection.
[0196] In some embodiments, when a terminal obtains first configuration information, it can send a request to the network device to request the network device to send first information. After sending the request to the network device, the terminal can attempt to receive the first information in the first cell and determine the state of the first cell based on whether the first information is received within a second time period.
[0197] For example, the first information is periodic information, and the second duration may include N periods of the first information, which may be agreed upon by the protocol, indicated by the network device, or determined based on the terminal's capabilities.
[0198] After sending a request message to the network device, the terminal can attempt to receive the first message in the first cell and determine whether it has received the first message within N periods. If the terminal receives the first message within N periods, it can be determined that the first cell is not blocked; if the terminal does not receive the first message within N periods, it can be determined that the first cell is blocked.
[0199] The following example illustrates how the terminal is in a non-connected state, such as the Radio Resource Control (RRC) idle state or the RRC inactive state, and how the state of the first cell is determined based on whether the terminal has obtained the first configuration information.
[0200] The request information, also known as the Wake-Up Signal (WUS), requests the network device to send the first information. For example, if the network device is in NES state, causing the first information to be in an on-demand state, the network device will stop sending the first information according to its configuration information. The WUS signal can be used to wake up the network device, for example, by requesting it to send the first information. The network device can then adjust the state of the first information to a non-on-demand state, for example, by continuing to send the first information according to its configuration information. Correspondingly, the first configuration information can also be called the Wake-Up Signal configuration information.
[0201] The process of this embodiment of the disclosure can be as follows:
[0202] In step 1:
[0203] 1> if the UE is in RRC_IDLE or in RRC_INACTIVE (when the terminal is in RRC_IDLE or RRC_INACTIVE state);
[0204] 2> if ssb-SubcarrierOffset indicates SIB1 is transmitted in the cell (TS 38.213
[13] ) and if SIB1 acquisition is required for the UE:
[0205] 3>Acquire the SIB1, which is scheduled as specified in TS 38.213
[13] (Terminal acquires SIB1, wherein the scheduling method of SIB1 is as specified in protocol TS 38.213
[13] );
[0206] 3> If the UE is unable to acquire the SIB1:
[0207] 4. Perform the actions as specified in Step 2.
[0208] In step 2:
[0209] The UE (terminal) shall:
[0210] 1> if in RRC_IDLE or in RRC_INACTIVE:
[0211] 2> If the UE is unable to acquire the SIB1:
[0212] 3> If the UE is an NES UE and obtains the WUS configuration:
[0213] 4> Send WUS and acquire the SIB1;
[0214] 3> else if the UE is an NES UE and does not obtain the WUS configuration information.
[0215] 4> If the intraFreqReselection field in the MIB message is set to "allowed":
[0216] 5> The UE may exclude the barred cell as a candidate for cell selection / reselection for up to 300 seconds.
[0217] 4> If the intraFreqReselection field in the MIB message is set to "not allowed":
[0218] 5> The UE may exclude the barred cell as a candidate for cell selection / reselection for up to 300 seconds.
[0219] 5> If the cell operates in the licensed spectrum:
[0220] 6> The UE shall not re-select to another cell on the same frequency as the barred cell and exclude such cell(s) as candidate(s) for cell selection / reselection for 300 seconds.
[0221] In some embodiments, the first configuration information is obtained in at least one of the following ways:
[0222] The first configuration information is obtained based on a predefined method;
[0223] Obtain the first configuration information based on the instruction signaling;
[0224] Obtain the first configuration information in the first cell;
[0225] Obtain the first configuration information from other cells besides the first cell.
[0226] In some embodiments, the terminal may obtain the first configuration information based on a predefined method. For example, the first configuration information may be agreed upon by a protocol, and the terminal may determine the first configuration information based on the protocol agreement.
[0227] In some embodiments, the terminal may obtain first configuration information based on indication signaling. For example, the indication signaling may be indication signaling in a first cell, or the indication information may be indication signaling from another cell outside the first cell, or the indication information may be indication information sent by a network device in the first cell, or the indication information may be indication signaling sent by a network device outside the first cell. The indication signaling may be broadcast signaling or unicast signaling, and this disclosure does not limit it.
[0228] In some embodiments, the terminal may obtain first configuration information in the first cell. For example, the network device may carry the first configuration information in the MIB or DCI in the first cell. The DCI used to carry the first configuration information includes, but is not limited to, DCI 1_0, such as DCI format 1_0 scrambled with System Information-RadioNetwork Temporary Identifier (SI-RNTI).
[0229] In some embodiments, the terminal can obtain the first configuration information in a cell other than the first cell. For example, the terminal can listen to the system information of other cells and obtain the first configuration information from the system information sent by other cells.
[0230] In some embodiments, the terminal may first attempt to obtain first configuration information in a first cell. If it fails to obtain the first configuration information in the first cell, it may attempt to obtain the first configuration information in a second cell. After obtaining the first configuration information in the second cell, the terminal can send a request message in the first cell based on the first configuration information.
[0231] In some embodiments, the type of the first cell includes one of the following:
[0232] Communities that support network energy saving;
[0233] Communities that do not support network energy saving;
[0234] Cells that support sending first information based on on-demand mode;
[0235] Cells that do not support sending first information based on on-demand mode;
[0236] Cells that send the first information based on an on-demand mode;
[0237] Cells that do not send the first information based on the on-demand mode.
[0238] In some embodiments, the terminal can determine the content indicated by the second indication information based on whether it has obtained the first configuration information (in this case, the second indication information is an implicit indication). For example, if the terminal has obtained the first configuration information, it can determine that the second indication information indicates a part of the type of the first cell. If the terminal fails to obtain the first configuration information, it can determine that the second indication information indicates another part of the type of the first cell.
[0239] In some embodiments, determining the state of the first cell based on the type of the first cell includes at least one of the following:
[0240] In response to the fact that the first cell is a cell that does not support network energy saving, and / or a cell that does not support sending the first information based on on-demand mode, and / or a cell that does not send the first information based on on-demand mode, it is determined that the first cell is in a disabled state.
[0241] In response to the fact that the first cell is a cell that supports network energy saving, and / or a cell that supports sending the first information based on on-demand mode, and / or a cell that sends the first information based on on-demand mode, it is determined that the first cell is in an unblocked state;
[0242] In response to the fact that the first cell is a cell that supports network energy saving, and / or a cell that supports sending the first information based on on-demand mode, and / or a cell that sends the first information based on on-demand mode, and the terminal obtains the first configuration information, it is determined that the first cell is in an unblocked state.
[0243] In response to the fact that the first cell is a cell that supports network energy saving, and / or a cell that supports sending the first information based on on-demand mode, and / or a cell that sends the first information based on on-demand mode, and the terminal fails to obtain the first configuration information, it is determined that the first cell is in a disabled state.
[0244] In response to the fact that the first cell is a cell that supports network energy saving, and / or a cell that supports sending the first information based on an on-demand mode, and / or a cell that sends the first information based on an on-demand mode, and the terminal fails to obtain the first configuration information, it is determined that the first cell is in a disabled state for a first period of time. In response to the fact that the terminal obtains the first configuration information for a first period of time, it is determined that the state of the first cell changes to an undisabled state.
[0245] In some embodiments, for the sake of simplicity, cells that do not support network energy saving, and / or cells that do not support sending the first information based on an on-demand mode, and / or cells that do not send the first information based on an on-demand mode, can be described as first cells of a first type; and cells that support network energy saving, and / or cells that support sending the first information based on an on-demand mode, and / or cells that send the first information based on an on-demand mode, can be described as first cells of a second type.
[0246] For example, if a terminal fails to receive the first information in a first cell, the terminal can determine the type of the first cell. If the first cell belongs to type 1, then it can be determined that the failure to receive the first information in the first cell is not due to the first cell supporting NES (e.g., the network device stops sending the first information because it is in NES mode), and / or not due to the first cell supporting on-demand transmission of the first information (e.g., the first information is in on-demand mode because the network device is in NES mode), and / or not due to the first cell transmitting the first information in on-demand mode (e.g., the first information in the first cell stops transmitting because it is in on-demand mode). Therefore, it is highly likely that the signal quality of the first cell is very poor for the terminal, causing the terminal to fail to receive the first information in the first cell. Thus, it can be determined that the first cell is in a disabled state.
[0247] For example, if a terminal fails to receive the first information in a first cell, the terminal can determine the type of the first cell. If the first cell belongs to the second type, it can be determined that the first information was not received in the first cell. This may be due to the first cell supporting NES (e.g., the network device stops sending the first information because it is in NES mode), and / or, it may be due to the first cell supporting on-demand transmission of the first information (e.g., the first information is in on-demand mode because the network device is in NES mode), and / or, it may be due to the first cell transmitting the first information in on-demand mode (e.g., the first information in the first cell stops transmitting because it is in on-demand mode), rather than because the signal quality of the first cell is poor for the terminal, causing the terminal to fail to receive the first information in the first cell. Therefore, it can be determined that the first cell is in an unblocked state.
[0248] In some embodiments, if the terminal determines that the first cell is of type 1, it can determine that the first cell is in a blocked state. In this case, the terminal can exclude the first cell from the candidate cells for cell selection and cell reselection for a period of time (e.g., 300 seconds). This period of time can be referred to as the first duration. The first duration can be agreed upon by the protocol, indicated by the network device, or determined based on the terminal's capabilities. During the first duration, the terminal performs cell selection or cell reselection without considering the first cell.
[0249] In some embodiments, if the terminal determines that the type of the first cell is the second type, it can determine that the first cell is in an unblocked state. In this case, the terminal can choose to send request information in the first cell according to the first configuration information to request the network device to send first information in the first cell; the terminal can also determine that the first cell belongs to the candidate cells for cell selection and cell reselection, so that when performing cell selection and cell reselection, it can determine whether it is necessary to select or reselect to the first cell, without ignoring the first cell.
[0250] In some embodiments, if the terminal determines that the type of the first cell is the second type, it can further determine whether the terminal has obtained the first configuration information. If the terminal obtains the first configuration information, it can determine that the first cell is in an unblocked state. If the terminal fails to obtain the first configuration information, it can determine that the first cell is in a blocked state.
[0251] In some embodiments, if the terminal determines that the type of the first cell is the second type and fails to obtain the first configuration information, it can determine that the first cell is in a blocked state and exclude the first cell from the candidate cells of cell selection and cell reselection for a period of time, such as this period of time can be called the first duration.
[0252] Within the first time period, the terminal may continue to attempt to obtain the first configuration information. If the terminal still fails to obtain the first configuration information within the first time period, the first cell remains in a blocked state; if the terminal obtains the first configuration information within the first time period, it can determine that the state of the first cell has changed to an unblocked state, and thus it can determine that the first cell belongs to the candidate cells for cell selection and cell reselection.
[0253] In some embodiments, if the terminal determines that the type of the first cell is the second type and has obtained the first configuration information, it can send a request message to the network device to request the network device to send the first information. After sending the request message to the network device, the terminal can attempt to receive the first information in the first cell and determine the state of the first cell based on whether the first information is received within a second time period.
[0254] For example, the first information is periodic information, and the second duration may include N periods of the first information, which may be agreed upon by the protocol, indicated by the network device, or determined based on the terminal's capabilities.
[0255] After sending a request message to the network device, the terminal can attempt to receive the first message in the first cell and determine whether it has received the first message within N periods. If the terminal receives the first message within N periods, it can be determined that the first cell is not blocked; if the terminal does not receive the first message within N periods, it can be determined that the first cell is blocked.
[0256] In some embodiments, the type of the first cell is determined based on at least one of the following:
[0257] Second indication information for network devices;
[0258] The signage for the first residential area;
[0259] The frequency band where the first cell is located.
[0260] In some embodiments, the type of the first cell may be determined based on predefined rules, or it may be indicated by a network device. For example, the network device may send second indication information to the terminal, which indicates the type of the first cell.
[0261] In some embodiments, the second indication information includes at least one of the following:
[0262] Master Information Block (MIB);
[0263] Physical Broadcast Channel (PBCH);
[0264] Scrambling sequences for physical broadcast channels.
[0265] For example, the free bits in the MIB can be used as a second indication.
[0266] For example, the reserved bits in the PBCH can be used as the second indication information. Regarding the reserved bits in the PBCH, please refer to the previous embodiment. The implementation of the second indication information is similar to that of the first indication information in this respect, and will not be repeated here.
[0267] For example, relevant parameters of the scrambling sequence of the physical broadcast channel can be used as the second indication information, or the initial value of the scrambling sequence of the physical broadcast channel can be used as the second indication information. Regarding the relevant parameters and initial value of the scrambling sequence of the physical broadcast channel, please refer to the previous embodiments. The implementation methods of the second indication information and the first indication information are similar in this respect, and will not be repeated here.
[0268] In some embodiments, where the type of the first cell is determined based on predefined rules, the predefined rules may include determining whether the identifier of the first cell belongs to an identifier set, and / or determining whether the frequency band in which the first cell is located belongs to a frequency band set.
[0269] In some embodiments, in response to the fact that the identifier of the first cell belongs to an identifier set, the first cell is determined to be a cell that supports network energy saving; and / or,
[0270] In response to the fact that the identifier of the first cell belongs to the identifier set, the first cell is determined to be a cell that supports sending the first information based on the on-demand mode; and / or,
[0271] In response to the fact that the identifier of the first cell does not belong to the identifier set, the first cell is determined to be a cell that does not support network energy saving; and / or,
[0272] In response to the fact that the identifier of the first cell does not belong to the identifier set, the first cell is determined to be a cell that does not support sending the first information based on the on-demand mode; and / or,
[0273] In response to the fact that the frequency band of the first cell belongs to a frequency band set, the first cell is determined to be a cell that supports network energy saving; and / or,
[0274] In response to the fact that the frequency band of the first cell belongs to a frequency band set, the first cell is determined to be a cell that supports the transmission of the first information based on an on-demand mode; and / or,
[0275] In response to the fact that the frequency band of the first cell does not belong to the frequency band set, the first cell is determined to be a cell that does not support network energy saving; and / or,
[0276] Since the frequency band of the first cell does not belong to the frequency band set, the first cell is determined to be a cell that does not support sending the first information based on the on-demand mode.
[0277] In some embodiments, the terminal can determine the type of the first cell based on whether its identifier belongs to an identifier set. For example, if the identifier of the first cell does not belong to the identifier set, the first cell can be determined to be of a first type, that is, a cell that does not support network energy saving, and / or a cell that does not support sending the first information based on an on-demand mode, and / or a cell that does not send the first information based on an on-demand mode. If the identifier of the first cell belongs to the identifier set, the first cell can be determined to be of a second type, that is, a cell that supports network energy saving, and / or a cell that supports sending the first information based on an on-demand mode, and / or a cell that sends the first information based on an on-demand mode.
[0278] In some embodiments, the second duration in the above embodiments may be associated with a cell; for example, the second duration corresponding to different cells may be different or the same.
[0279] It should be noted that the set of identifiers can be predefined or indicated by the network device, and this disclosure does not limit it in this respect.
[0280] In some embodiments, the terminal can determine the type of the first cell based on whether its frequency band belongs to a frequency band set. For example, if it is determined that the frequency band of the first cell does not belong to a frequency band set, the first cell can be determined to be of a first type, that is, a cell that does not support network energy saving, and / or a cell that does not support sending the first information based on an on-demand mode, and / or a cell that does not send the first information based on an on-demand mode. If it is determined that the frequency band of the first cell belongs to an identifier set, the first cell can be determined to be of a second type, that is, a cell that supports network energy saving, and / or a cell that supports sending the first information based on an on-demand mode, and / or a cell that sends the first information based on an on-demand mode.
[0281] In some embodiments, the second duration in the above embodiments may be associated with a frequency band. For example, the second duration corresponding to different frequency bands may be different or the same.
[0282] It should be noted that the frequency band set can be predefined or indicated by the network device, and this disclosure does not limit it.
[0283] In some embodiments, the network device determines whether to send the first message based primarily on the number of connected terminals and service conditions, such as sending the first message on demand. For example, if the number of connected terminals is small and service demand is low during non-working hours, the network device stops sending the first message and sends it only after receiving a request. Conversely, if the number of connected terminals is high and service demand is high during working hours, the network device sends the first message in normal mode (e.g., according to the configuration information of the first message). Therefore, the cell type may change over time.
[0284] Based on this, in some embodiments, when the terminal determines that the first cell is of the second type based on the identifier of the first cell belonging to the identifier set, it can determine that the first cell is of the second type within a period of time t, and determine that the first cell is of the first type outside of time t.
[0285] In some embodiments, when a terminal determines that the first cell is of the second type based on the frequency band of the first cell belonging to the frequency band set, it can determine that the first cell is of the second type within a time period t, and determine that the first cell is of the first type outside of time t.
[0286] The communication method involved in the embodiments of this disclosure may include at least one of steps S201 to S202. For example, step S201 may be implemented as a standalone embodiment, step S202 may be implemented as a standalone embodiment, and step S201+S202 may be implemented as a standalone embodiment, but is not limited thereto.
[0287] In some embodiments, steps S201 and S202 may be performed in an alternate order or simultaneously.
[0288] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.
[0289] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0320] Secondly, embodiments of this disclosure propose a status indication method.

[0323] It should be noted that, Figure 4 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.
[0324] In some embodiments, the first indication information includes at least one of the following: Master Information Block (MIB); Physical Broadcast Channel (PBCH); and scrambling sequence of the Physical Broadcast Channel.
[0325] In some embodiments, during communication in a first frequency domain, the first indication information includes information based on the physical broadcast channel; and / or, during communication in a second frequency domain, the first indication information includes the master information block; and / or

[0328] In some embodiments, the relevant parameters are determined based on at least one of the following: bits in the system frame number (SFN); half-frame indicator bits.
[0329] In some embodiments, the first information includes at least one of the following: System Information Block SIB1; Synchronous Advertising Signal Block SSB.
[0330] In some embodiments, the method further includes sending second indication information to the terminal, wherein the second indication information is used to indicate the type of the first cell.
[0331] The second aspect and optional implementations of the optional embodiments of the second aspect can be found in [reference]. Figure 2 Optional implementation methods in the illustrated embodiments, and Figure 2 Other related parts in the embodiments involved will not be described in detail here.
[0332] In some embodiments, a terminal supporting network energy saving receives indication information to determine the corresponding cell status when SIB1 cannot be obtained. Correspondingly, the network device transmits indication information for the terminal to determine the corresponding cell status when SIB1 cannot be obtained. The following describes specific inventive solutions based on different indication information;
[0333] Example 1.1: The indication information is based on the reserved bit indication carried by the MIB and / or PBCH.
[0334] Based on different SSB patterns and frequency ranges, the reserved bits carried by the PBCH are shown in Table 3 below:
[0335]
[0336] Table 3
[0337] For example, in the FR1 licensed scenario, the reserved bits carried by the PBCH are:
[0338] For example, the indication information is based on the information carried by the PBCH. bit or Bit indication.
[0339] For example, the indication information is based on the spare bit indication in the MIB.
[0340] For example, in the FR1 scenario, the indication information is based on the information carried by the PBCH. bit or Bit indication; in the FR2 scenario, the indication information is based on the spare bit indication in the MIB.
[0341] For example, in the FR1 scenario, the indication information is based on the information carried by the PBCH. bit or Bit indication; In the FR2 scenario, the indication information is determined based on the PBCH scrambling method, and the specific scrambling method is described in Example 1.2.
[0342] For example, when the indication information indicates a first value, e.g., 0, the terminal determines that the cell is in a barred state and excludes the cell from the cell selection / reselection candidate cell range for a first time length. The first time length is determined based on a predefined method, signaling configuration, or UE capability; for example, the first time length is equal to 300 seconds. Within the first time length, the terminal will not select to camp on the current cell.
[0343] For example, when the indication information indicates a second value, e.g., the indication is 1, the terminal determines that the cell is in a not barred state and includes the cell in the cell selection / reselection candidate cell range;
[0344] For example, if the terminal determines that the cell is in a not-barred state, under the condition that the terminal obtains the first configuration information, the terminal sends a trigger information to trigger the network device to send SIB1 and attempt to receive SIB1. The first configuration information is based on the above definition and will not be repeated here. Correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
[0345] Example 1.2: The indication information is indicated based on the PBCH scrambling method.
[0346] For example, the indication method is determined based on the v value of the PBCH scrambling sequence. For users who support network energy saving, if the v value belongs to a first set of values, the terminal determines that the cell is in a barred state; if the v value belongs to a second set of values, the terminal determines that the cell is in a not barred state.
[0347] For example, the first set of values shown is {0,1}, and the second set of values is {2,3}, corresponding to the second and third values of v based on SFN. The correspondence is confirmed and shown in Table 1 above.
[0348] For example, the first set of values shown is {0,1,2,3}, and the second set of values is {4,5,6,7}, corresponding to v values based on half-frame indicator bits, i.e., The second and third LSBs of the SFN are determined, and the corresponding relationship is shown in Table 2 above.
[0349] For example, the indication method is determined based on the initial value of the PBCH scrambling sequence. For example, if the initial value of the first m-sequence x1(n) corresponding to the PBCH scrambling sequence is determined as follows: x1(0) = 1, x1(n) = 0, n = 0, 1, 2, ..., 30, the terminal determines that the cell is in a barred state; if the initial value of x1(n) is determined as follows: x1(1) = 1, x1(n) = 0, n = 0, 2, 3, ..., 30, the terminal determines that the cell is not in a barred state.
[0350] For example, if the terminal determines that the cell is in a barred state and excludes the cell from the cell selection / reselection candidate cell range for a first time length, the first time length is determined based on a predefined method, signaling configuration, or UE capability; for example, the first time length is equal to 300 seconds. During the first time length, the terminal will not select to camp on the current cell.
[0351] For example, if the terminal determines that the cell is in a not-barred state, under the condition that the terminal obtains the first configuration information, the terminal sends a trigger information to trigger the network device to send SIB1 and attempt to receive SIB1. The first configuration information is based on the above definition and will not be repeated here. Correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
[0352] Example 1.3: The terminal determines the status of the current cell based on whether it has obtained the first configuration information corresponding to the current cell.
[0353] For example, the configuration information is used by the terminal to send trigger information to trigger cell system information transmission; for example, the configuration information can be WUS configuration, and the trigger information can be WUS. The terminal can obtain the first configuration information based on other cell indication information, or based on the current cell indication information, or based on a predefined method; this invention does not limit this.
[0354] For example, if a terminal obtains the WUS configuration corresponding to the current cell, the terminal determines that it can obtain the corresponding SIB1 by sending WUS. The terminal determines that the cell is in a not-barred state, sends WUS, triggering the network device to send SIB1 and attempt to receive SIB1; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
[0355] For example, if the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal determines that it cannot obtain the corresponding SIB1 by sending WUS. The terminal determines that the cell is in a barred state and excludes the cell from the cell selection / reselection candidate cell range for a first time length. The first time length is determined based on a predefined method, signaling configuration, or UE capability. For example, the first time length is equal to 300 seconds. Within the first time length, the terminal will not choose to camp on the current cell.
[0356] For example, if the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal determines that it cannot obtain the corresponding SIB1 by sending WUS. The terminal determines that the cell is in a barred state and temporarily excludes the cell from the cell selection / reselection candidate cell range for a first time length. The first time length is determined based on a predefined method, signaling configuration, or UE capability. For example, the first time length is equal to 300 seconds. Within the first time length,
[0357] If the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal will not choose to camp on the current cell;
[0358] If the terminal obtains the WUS configuration corresponding to the current cell within the first time period, the terminal updates the current cell status to the not barred state, sends WUS, triggers the network device to send SIB1, and attempts to receive SIB1; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
[0359] For example, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines whether the cell is in a barred state based on the second condition, specifically including:
[0360] If the terminal fails to obtain SIB1 information after sending WUS for N SIB1 configuration cycles, it determines that the cell is in a barred state; otherwise, the terminal determines that the cell is in a not barred state.
[0361] If the terminal does not obtain SIB1 after sending WUS, the terminal continues to send WUS. If SIB1 information is still not obtained after sending WUS N times, the terminal determines that the cell is in a barred state; otherwise, the terminal determines that the cell is in a not barred state.
[0362] The N is determined based on predefined, signaling configuration, or predefined methods.
[0363] In some embodiments, the terminal supporting network energy saving determines the cell type and, based on the cell type, determines the corresponding cell state when SIB1 cannot be obtained.
[0364] Example 2.1: Terminals supporting network energy saving determine the cell type based on indication information. Based on the cell type, they determine the corresponding cell state when SIB1 cannot be obtained.
[0365] Correspondingly, the network device sends an indication message to indicate the corresponding cell type.
[0366] For example, the indication information is based on the reserved bits of MIB and / or PBCH, and the specific indication method is described in Example 1.1, which will not be repeated here;
[0367] For example, the indication information is based on the PBCH scrambling method, and the specific indication method is described in Example 1.2, which will not be repeated here;
[0368] For example, the indication information is based on whether a WUS configuration indication is obtained. The specific indication method is described in Example 1.3, and will not be repeated here.
[0369] For example, if the indication information indicates that the cell type is a cell that supports network energy saving and / or a cell that supports sending system information in on-demand mode, when the terminal cannot obtain SIB1, the terminal determines that the cell is in a not barred state and includes the cell in the cell selection / reselection candidate cell range;
[0370] For example, if the terminal determines that the cell is in a not-barred state, under the condition that the terminal obtains the first configuration information, the terminal sends a trigger information to trigger the network device to send SIB1 and attempt to receive SIB1. The first configuration information is based on the above definition and will not be repeated here. Correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
[0371] For example, if the terminal determines that the cell is in a not-barred state, and the terminal has not obtained the first configuration information, the terminal searches for other cells and attempts to receive system information from other cells in order to obtain the first configuration information corresponding to the current cell.
[0372] For example, if the indication information indicates that the cell type is a cell that supports network energy saving and / or a cell that supports sending system information in on-demand mode, when the terminal cannot obtain SIB1, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines that the cell is in a not barred state and includes the cell in the cell selection / reselection candidate cell range.
[0373] For example, if the indication information indicates that the cell type is a cell that supports network energy saving and / or a cell that supports sending system information in on-demand mode, when the terminal cannot obtain SIB1, if the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal determines that the cell is in a barred state and excludes the cell from the cell selection / reselection candidate cell range for a first time length. The first time length is determined based on a predefined method, signaling configuration, or UE capability. For example, the first time length is equal to 300 seconds. Within the first time length, the terminal will not choose to camp on the current cell.
[0374] For example, if the indication information indicates that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand transmission of system information, and the terminal cannot obtain SIB1, if the terminal has not obtained the WUS configuration corresponding to the current cell, the terminal determines that it cannot obtain the corresponding SIB1 based on the method of sending WUS. The terminal determines that the cell is in a barred state and temporarily excludes the cell from the cell selection / reselection candidate cell range for a first time length. The first time length is determined based on a predefined method, signaling configuration, or UE capability. For example, the first time length is equal to 300 seconds. Within the first time length,
[0375] If the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal will not choose to camp on the current cell;
[0376] If the terminal obtains the WUS configuration corresponding to the current cell within the first time period, the terminal updates the current cell status to the not barred state, includes the cell in the cell selection / reselection range, sends WUS, triggers the network device to send SIB1, and attempts to receive SIB1; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
[0377] Example 2.2: Terminals supporting network energy saving determine the cell type based on a predefined method. Based on the cell type, they determine the corresponding cell state when SIB1 cannot be obtained.
[0378] For example, the terminal determines whether a cell supports network energy saving and / or supports on-demand transmission of system information based on whether the cell ID belongs to a first set. That is, if the cell ID belongs to the first set, the terminal determines that the cell supports network energy saving and / or supports on-demand transmission of system information, and vice versa;
[0379] For example, the terminal determines whether a cell supports network energy saving and / or supports on-demand transmission of system information based on whether the cell band belongs to the first set. That is, if the cell band belongs to the first set, the terminal determines that the cell supports network energy saving and / or supports on-demand transmission of system information, and vice versa;
[0380] For example, the first set is determined based on signaling indications or a predefined method;
[0381] In one scenario, network devices primarily determine whether to send system information on demand based on factors such as the number of connected users and service demand. For example, during non-working hours, when the number of connected users is relatively small and service demand is low, the network device stops sending system information and sends it only after receiving a trigger message. Conversely, during working hours, when the number of connected users is relatively large and service demand is high, the network device sends system information in normal mode. Therefore, the cell type may change over time.
[0382] Based on the above background, another possible implementation is that, within a first time period, the terminal determines whether the cell supports network energy saving and / or supports on-demand transmission of system information based on whether the cell ID belongs to a first set. That is, if the cell ID belongs to the first set, the terminal determines that the cell supports network energy saving and / or supports on-demand transmission of system information, and vice versa.
[0383] Outside of the first time period, the terminal determines that the cell is a cell that does not support network energy saving and / or does not send system information based on on-demand mode;
[0384] Based on the above background, another possible implementation is that, within a first time period, the terminal determines whether the cell is a cell that supports network energy saving and / or a cell that supports on-demand transmission of system information based on whether the cell's band belongs to a first set. That is, if the cell belongs to the first set, the terminal determines that the cell is a cell that supports network energy saving and / or a cell that supports on-demand transmission of system information, and vice versa;
[0385] Outside of the first time period, the terminal determines that the cell is a cell that does not support network energy saving and / or does not send system information based on on-demand mode;
[0386] For example, the second time period is determined based on signaling indication or a predefined method. The second time period can be in units such as h, minute, s, frame, subframe, time slot, OFDM symbol, etc. For example, the second time periods corresponding to different cell IDs or cell ID groups can be the same or different.
[0387] For example, the first set is determined based on signaling indications or a predefined method;
[0388] For example, if the terminal determines the cell type as a cell that supports network energy saving and / or a cell that supports sending system information in on-demand mode based on a predefined method, when the terminal cannot obtain SIB1, the terminal determines that the cell is in a notbarred state and includes the cell in the cell selection / reselection candidate cell range;
[0389] For example, if the terminal determines that the cell is in a not-barred state, under the condition that the terminal obtains the first configuration information, the terminal sends a trigger information to trigger the network device to send SIB1 and attempt to receive SIB1. The first configuration information is based on the above definition and will not be repeated here. Correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
[0390] For example, if the terminal determines that the cell is in a not-barred state, and the terminal has not obtained the first configuration information, the terminal searches for other cells and attempts to receive system information from other cells in order to obtain the first configuration information corresponding to the current cell.
[0391] For example, if the terminal determines the cell type as a cell that supports network energy saving and / or a cell that supports sending system information in on-demand mode based on a predefined method, and the terminal cannot obtain SIB1, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines that the cell is in a not barred state and includes the cell in the cell selection / reselection candidate cell range.
[0392] For example, if the terminal determines, based on a predefined method, that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand transmission of system information, and the terminal cannot obtain SIB1, if the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal determines that the cell is in a barred state and excludes the cell from the cell selection / reselection candidate cell range for a first time length. This first time length is determined based on a predefined method, signaling configuration, or UE capabilities; for example, the first time length is equal to 300 seconds. Within this first time length, the terminal will not choose to camp on the current cell.
[0393] For example, if the terminal determines, based on a predefined method, that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand transmission of system information, and the terminal cannot obtain SIB1, if the terminal has not obtained the WUS configuration corresponding to the current cell, the terminal determines that it cannot obtain the corresponding SIB1 by sending WUS. The terminal determines that the cell is in a barred state and temporarily excludes the cell from the cell selection / reselection candidate cell range for a first time length. The first time length is determined based on a predefined method, signaling configuration, or UE capability; for example, the first time length is equal to 300 seconds. Within the first time length,
[0394] If the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal will not choose to camp on the current cell;
[0395] If the terminal obtains the WUS configuration corresponding to the current cell within the first time period, the terminal updates the current cell status to the not barred state, includes the cell in the cell selection / reselection range, sends WUS, triggers the network device to send SIB1, and attempts to receive SIB1; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
