[0097] In some embodiments, the terminal may perform operations such as cell selection and cell reselection in candidate cells in the communication system, so as to determine an appropriate cell to camp on.

[0098] In some embodiments, the main purpose of cell selection is for the terminal to quickly select a cell with a signal quality meeting the conditions and camp on it under the selected PLMN (Public Land Mobile Network). The terminal determines whether the cell selection conditions are met based on the measured cell signal strength (such as Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ)) and related parameters, and these related parameters can be configured based on System Information Block (SIB) 1.

[0099] In some embodiments, the main purpose of cell reselection is to help the terminal camp on a cell with better signal quality and higher priority. The UE that can perform cell reselection must at least meet the following conditions:

[0100] The terminal is in a non-connected state:

[0101] The terminal has camped on a cell (e.g., completed the cell selection process).

[0102] The UE meeting the above conditions can select a more suitable cell by continuously performing cell quality detection and / or measurement.

[0103] In some embodiments, when the terminal performs cell selection or reselection among candidate cells, it can receive the first information in the candidate cell, such as System Information Block (SIB) 1. When the terminal fails to 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, exclude the first cell from the candidate cells for a period of time (e.g., 300 seconds). Then, when the terminal performs cell selection or reselection during this period, it will not use the first cell as a candidate cell and thus will not select or reselect to the first cell.

[0104] However, there are many reasons why the terminal cannot receive the first information in the first cell. For example, the signal quality of the first cell is too poor for the terminal. Although the network device sends the first information in the first cell, the terminal cannot receive the first information. For example, the network device is about to enter the Network Energy Saving (NSE) mode, or is already in the NES mode. The first information in the first cell can be in an on-demand state, that is, 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 message to the network device. After receiving the request message, the network device can choose to send the first information in the first cell.

[0105] It can be seen that the reason why the terminal cannot receive the first information in the first cell may not be due to the too poor signal quality of the first cell for the terminal. It is possible that the first information is in an on-demand state in the first cell, rather than because the signal quality of the first cell for the terminal is poor.

[0106] In this case, if the terminal cannot receive the first information in the first cell and directly determines that the first cell is in a prohibited state, it is inaccurate. For example, for a specific first cell, it is possible that the signal quality of the first cell is acceptable for the terminal, but the first information in the first cell is in an on-demand state, causing the terminal to determine the first cell as a prohibited state and no longer attempt to camp on the first cell, resulting in few terminals camping on the first cell and wasting the wireless resources in the network.

[0107] Figure 2 It is an interaction schematic diagram of a state determination method shown according to an embodiment of the present disclosure.

[0108] As Figure 2 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 the first information of the first cell based on a first condition. That is to say, when the first condition is satisfied, the terminal may attempt to obtain the first information of the first cell.

[0111] In some embodiments, the first condition may include at least one of the following:

[0112] The terminal is in a non-connected state, where the non-connected state includes at least one of the following: idle state, inactive state;

[0113] The terminal obtains indication information for indicating the transmission of first information in a first cell. For example, the indication information may include an information element (IE) ssb-SubcarrierOffset (which may be translated as Synchronous Broadcast Signal Block Subcarrier Offset, for example).

[0114] The terminal sends request information to the network device, where the request information is used to request the network device to send the first information.

[0115] The terminal is in a connected state and receives a system information change indication.

[0116] The terminal is in a connected state, and the T311 timer (the specific meaning can refer to related technologies, and the meaning is not elaborated herein) is running.

[0117] The terminal is in a connected state and fails to obtain a valid version of the system information, or does not obtain valid system information (such as SIB1) during the current modification period.

[0118] For example, in some embodiments, when the terminal is in a non-connected state, the terminal may attempt to obtain the first information of the first cell.

[0119] In some embodiments, when the 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 the terminal sends request information to the network device to request the network device to send the 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 the terminal 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 obtain the first information of the first cell. Regarding the start and operation mechanism of the T311 timer, there have been detailed descriptions in related technologies and will not be elaborated herein.

[0122] In some embodiments, when the terminal is in a connected state and the terminal fails to obtain a valid version of the system information, or does not obtain valid system information during the current modification period, 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 some embodiments, the terminal fails to obtain the first information of the first cell.

[0124] In step S202, in response to the terminal's failure to obtain the first information of the first cell, the terminal determines the state of the first cell, where the state of the first cell includes:

[0125] The first cell is in a barred state; or

[0126] The first cell is in a not barred state.

[0127] The terminal attempts to obtain the first information of the first cell and determines the state of the first cell according to the obtained result. In some embodiments, the terminal determines that it has obtained the first information of the first cell, and thus can perform cell selection / reselection or residence for the first cell based on this first information.

[0128] In some embodiments, the terminal determines that it fails to obtain the first information, which can be determined based on the terminal's implementation or based on a predefined method. In short, the terminal determines that the acquisition of the first information is unsuccessful.

[0129] For example, when the terminal determines based on its own implementation that it fails to obtain the first information, it may include that the terminal attempts to obtain the first information based on a first condition and attempts to obtain the first information one or more times during the transmission period of the first information, but fails to successfully obtain the first information, and the terminal determines that it cannot obtain the first information in the first cell.

[0130] For example, when the terminal determines based on a predefined method that it fails to obtain the first information, the predefined rule may include that the terminal attempts to obtain the first information based on a first condition and attempts to obtain the first information during n (n is an integer greater than or equal to 1, which can be determined by protocol agreement, network indication, or based on terminal capabilities) transmission periods of the first information, and the terminal determines that it cannot obtain the first information in the first cell.

[0131] In some embodiments, when the terminal attempts to obtain the first information in the first cell but fails to obtain it, it can be determined that the first information of the first cell cannot be obtained. In this case, according to the embodiments of the present disclosure, the first cell may not be directly determined to be in a barred state, but rather it is further determined whether the first cell is specifically in a barred state or in a not barred state. That is, when the terminal fails to obtain the first information, the terminal will not directly determine that the first cell is in a barred state, but there will be a subsequent determination mechanism to verify the state of the first cell. To avoid misdetermining the first cell in a not barred state as being in a barred state.

[0132] Accordingly, it is beneficial to avoid determining the first cell as a prohibited state when the first information is in a 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 causing waste of radio 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 PBCH Block (SSB).

[0136] It should be noted that the first information is not limited to the above SSB and SIB1, and 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 signals and secondary synchronization signals, Discovery reference signal (DRS), etc.

[0137] In some embodiments, when the terminal determines that the first cell is in a prohibited state, it may 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 may be agreed upon by the protocol, or may be indicated by the network device, or may be determined based on the terminal's capabilities. The terminal will not consider the first cell when performing cell selection or cell reselection during this period of time.

[0138] In some embodiments, when the terminal determines that the first cell is not in a prohibited state, if the first terminal can obtain the first configuration information, it may 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 the terminal determines that the first cell is not in a prohibited state, it may determine that the first cell belongs to the candidate cells for cell selection and cell reselection, so that the first cell can be considered when performing cell selection and cell reselection.

[0139] For example, it is possible to request a network device to send first information in a first cell, or it is also possible to request the network device to send the first information in other cells. Among them, when the other cell is not a cell under the network device of the first cell, the network device of the first cell may forward the request information to the network device of the other cell, so as to request the network device of the other cell to send the first information in the other cell.

[0140] It should be noted that under different network devices and / or in different cells, the first configuration information used to send the request information may be the same or different. In this regard, the present disclosure does not limit this.

[0141] The following uses several embodiments to exemplarily illustrate how to determine the state of the first cell when the terminal cannot 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] Determine the state of the first cell according to the first indication information of the network device;

[0144] Determine the state of the first cell according to whether the terminal obtains the first configuration information. For example, the first configuration information may be used for the terminal to send a request information to the network device, and the request information is used to request the network device to send the first information;

[0145] Determine the state of the first cell according to the type of the first cell.

[0146] It should be noted that the method for determining the state of the first cell may not be limited to the above several types. In this regard, the present disclosure does not limit this.

[0147] For example, when the terminal cannot obtain the first information of the first cell, it may send a request information to the network device according to the first configuration information to request the network device to send the first information in the first cell. Furthermore, the terminal may determine the state of the first cell according to whether it can receive the first information in the first cell after sending the request information. For example, if the first information cannot be received in the first cell after sending the request information, it may be determined that the first cell is in a prohibited state; if the first information can be received in the first cell after sending the request information, it may be determined that the first cell is in an unprohibited state, and the previous inability to obtain the first information is not because the first cell is prohibited, 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 sequence of the Physical Broadcast Channel.

[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 among the bits of the PBCH and / or bits. For example, when communicating in the FR1 frequency band, the reserved bits in the PBCH can include and bits.

[0155] In some embodiments, determining the state of the first cell includes at least one of the following:

[0156] In response to the terminal communicating in the first frequency domain range FR1, according to the state of the first cell of the Physical Broadcast Channel;

[0157] In response to the terminal communicating in the second frequency domain range FR2, determining the state of the first cell according to the Master Information Block;

[0158] In response to the terminal communicating in the second frequency domain range FR2, determining the state of the first cell according to the scrambling sequence of the Physical Broadcast Channel.

[0159] For example, the first frequency domain range can include the FR1 frequency band, and the second frequency domain range can include the FR2 frequency band.

[0160] It should be noted that in the scenarios of communicating in the first frequency domain range and communicating in the second frequency domain range, determining the state of the first cell may not be limited to the methods shown in the above embodiments, and the present disclosure does not limit this. For example, when communicating in the first frequency domain range, the state of the first cell can also be determined according to the MIB, or according to the scrambling sequence of the PBCH; for example, when communicating in the second frequency domain range, the state of the first cell can also be determined according to 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 prohibited 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 unprohibited state.

[0162] In some embodiments, determining the state of a first cell according to the scrambling sequence of the physical broadcast channel includes at least one of the following:

[0163] Determining the state of the first cell according to the relevant parameters of the scrambling sequence of the physical broadcast channel;

[0164] Determining the state of the first cell according to 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 can refer to the related art, and the present disclosure does not elaborate on its meaning here). It should be noted that the relevant parameters of the PBCH scrambling sequence are not limited to the v value. For example, it may also be the length of the PBCH scrambling sequence. In this regard, the present disclosure does not limit it.

[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 may determine whether the v value belongs to a first value set. If the v value belongs to the first value set, it may be determined that the first cell is in a prohibited state; if the v value does not belong to the first value set, it may be determined that the first cell is in an unprohibited state.

[0168] For example, the terminal may determine the value set to which the v value belongs. If the v value belongs to the first value set, it may be determined that the first cell is in a prohibited state; if the v value belongs to the second value set, it may be determined that the first cell is in an unprohibited 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 indication bits.

[0172] For example, the v value may be determined based on the second least significant bit (LSB) and the third LSB in the SFN, where the second LSB and the third LSB may be expressed as the and bits in the SFN. The correspondence between the value x of the second LSB and the value y of the third LSB and the v value may be as 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, take the case where the terminal determines the state of the first cell based on the value set to which the v value belongs. For example, the first value set is {0, 1}, the second value set is {2, 3}, and when the terminal determines that the v value is 2, it can be determined that the v value belongs to the second value set, and further determine that the first cell is in an unrestricted state.

[0176] For example, the v value can be determined based on the half-frame indication bit, and the second LSB and the third LSB in the SFN. Among them, the half-frame indication bit can be expressed as in the SFN bit. The value z of the half-frame indication bit, the value x of the second LSB, and the value y of the third LSB, the corresponding relationship with 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, take the case where the terminal determines the state of the first cell based on the value set to which the v value belongs. For example, the first value set is {0, 1, 2, 3}, the second value set is {4, 5, 6, 7}, and when the terminal determines that the v value is 5, it can be determined that the v value belongs to the second value set, and further determine that the first cell is in an unrestricted state.

[0180] In some embodiments, the terminal can determine the state of the first cell according to the initial value of the scrambling sequence of the PBCH.

[0181] For example, in the first m sequence corresponding to the scrambling sequence of the PBCH (the specific meaning can refer to the related art, and the present disclosure does not elaborate on its meaning here), if x 1 (n) has an initial value determined based on the first method, the terminal can determine that the first cell is in a prohibited state. If x 1 (n) has an initial value determined based on the second method, the terminal can determine that the first cell is in an unrestricted state.

[0182] For example, the first method may include: x 1 (0) = 1, x 1 (n) = 0, n = 0, 1, 2,..., 30.

[0183] For example, the second method may include: x 1 (1) = 1, x 1 (n) = 0, n = 0, 2, 3,..., 30.

[0184] In some embodiments, determining the state of the first cell according to whether the terminal obtains the first configuration information includes at least one of the following:

[0185] In response to the terminal obtaining the first configuration information, determine that the first cell is in an unrestricted state;

[0186] In response to the terminal failing to obtain the first configuration information, it is determined that the first cell is in a prohibited state;

[0187] In response to the terminal failing to obtain the first configuration information, it is determined that the first cell is in a prohibited state within a first duration. In response to the terminal obtaining the first configuration information within the first duration, it is determined that the state of the first cell changes to an unprohibited state.

[0188] In some embodiments, the first configuration information can be used by the terminal to send a request message to the network device to request the network device to send the first information.

[0189] Among them, the request message can request the network device to send the first information in the first cell, or can request the network device to send the first information in other cells. Among them, when the other cell is not a cell under the network device of the first cell, the network device of the first cell can forward the request message to the network device of the other cell, so as to request the network device of the other cell to send the first information in the other cell.

[0190] It should be noted that under different network devices, and / or, in different cells, the first configuration information used to send the request message can be the same or different. In this regard, the present disclosure does not limit this.

[0191] In some embodiments, when the terminal obtains the first configuration information, it can be determined that the first cell is in an unprohibited state. In this case, the terminal can choose to send a request message in the first cell according to the first configuration information to request the network device to send the 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 be determined whether it is necessary to select or reselect to the first cell, and the first cell will not be ignored.

[0192] In some embodiments, when the terminal fails to obtain the first configuration information, it can be determined that the first cell is in a prohibited 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 (for example, 300 seconds). For example, this period of time can be called the first duration, and the first duration can be agreed upon by the protocol, or can be indicated by the network device, or can be determined based on the terminal capabilities. When the terminal performs cell selection or cell reselection within the first duration, the first cell will not be considered.

[0193] It should be noted that in the embodiments of the present disclosure, when the terminal fails to obtain the first configuration information, it may include that the first configuration information is received based on the reception period of the first configuration information, and the first configuration information is not received in one period, or the first configuration information is not received in multiple periods of the period number threshold, and it can be determined that the first configuration information has not been received.

[0194] In some embodiments, when the terminal fails to obtain the first configuration information, it can be determined that the first cell is in a prohibited state, and the first cell is excluded from the candidate cells for cell selection and cell reselection for a period of time. For example, this period of time can be referred to as the first duration.

[0195] Within the first duration, the terminal can continue to attempt to obtain the first configuration information. If the terminal still fails to obtain the first configuration information within the first duration, then the first cell remains in the prohibited state; if the terminal obtains the first configuration information within the first duration, it can be determined that the state of the first cell changes to an unprohibited state, and thus it can be determined that the first cell belongs to the candidate cells for cell selection and cell reselection.

[0196] In some embodiments, when the terminal obtains the first configuration information, 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. After the terminal sends the request message to the network device, it can attempt to receive the first information in the first cell and determine the state of the first cell according to whether the first information is received within the second duration.

[0197] For example, if the first information is periodic information, the second duration can include N periods of the first information, where it can be agreed by the protocol, or indicated by the network device, or determined based on the terminal capabilities.

[0198] After the terminal sends the request message to the network device, it can attempt to receive the first information in the first cell and determine whether the first information is received within N periods of the first information. If the terminal receives the first information within N periods of the first information, it can be determined that the first cell is in an unprohibited state; if the terminal does not receive the first information within N periods of the first information, it can be determined that the first cell is in a prohibited state.

[0199] Taking the example that the terminal is in a non-connected state, for example, the terminal is in the Radio Resource Control (RRC) idle (RRC_idle) state or the RRC_inactive state, and determining the state of the first cell according to whether the terminal obtains the first configuration information, an exemplary description is given.

[0200] Among them, the request information can also be referred to as a Wake Up Signal (WUS). The wake-up signal can request the network device to send the first information. For example, if the network device is in the NES state, resulting in the first information being in a demand state, then the network device will stop sending the first information according to the configuration information of the first information. The wake-up signal can be used to wake up the network device. For example, by requesting the network device to send the first information, the network device can adjust the state of the first information to a non-demand state, such as continuing to send the first information according to the configuration information of the first information. Correspondingly, the first configuration information can also be referred to as wake-up signal configuration information.

[0201] The process of the embodiments of the present 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 the RRC_IDLE state or the RRC_INACTIVE state);

[0204] 2> if ssb-SubcarrierOffset indicates that SIB1 is transmitted in the cell (TS 38.213

[13] ) and if SIB1 acquisition is required for the UE (if ssb-SubcarrierOffset indicates that SIB1 is transmitted in the cell (the cell defined based on protocol TS 38.213

[13] ), and when the terminal needs to acquire SIB1):

[0205] 3> acquire the SIB1, where the scheduling method of SIB1 is as specified in TS 38.213

[13] (the terminal acquires SIB1, where 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 (if the terminal cannot acquire SIB1):

[0207] 4> perform the actions as specified in Step 2 (perform the operations specified in Step 2);

[0208] In step 2:

[0209] The UE shall (the terminal will):

[0210] 1> if in RRC_IDLE or in RRC_INACTIVE (If in the RRC_IDLE state or the RRC_INACTIVE state):

[0211] 2> if the UE is unable to acquire the SIB1 (If the terminal is unable to obtain SIB1):

[0212] 3> if the UE is a NES UE and obtains the WUS configuration (The terminal is a NES terminal (e.g., supports NES function) and obtains the WUS configuration information):

[0213] 4> send WUS and acquire the SIB1 (Send WUS and obtain SIB1);

[0214] 3> else if the UE is a NES UE and does not obtain the WUS configuration (Otherwise, if the terminal is a NES terminal and does not obtain the WUS configuration information)

[0215] 4> If the field intraFreqReselection in the MIB message is set to "allowed" (When 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 (The terminal will exclude the barred cell from the candidates for cell selection / reselection within 300 seconds);

[0217] 4> If the field intraFreqReselection in the MIB message is set to "not allowed" (When 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 (the UE will exclude the barred cell from the candidates for cell selection / reselection within 300 seconds);

[0219] 5>If the cell operates in licensed spectrum (If the cell operates in the licensed frequency band):

[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 (The terminal shall not reselect to another cell on the same frequency as the barred cell and shall exclude such cell(s) from the candidates for cell selection / reselection within 300 seconds).

[0221] In some embodiments, the method for obtaining the first configuration information includes at least one of the following:

[0222] Obtain the first configuration information based on a predefined method;

[0223] Obtain the first configuration information based on indication signaling;

[0224] Obtain the first configuration information in the first cell;

[0225] Obtain the first configuration information in a cell other than 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 the protocol, and the terminal may determine the first configuration information based on the protocol agreement.

[0227] In some embodiments, the terminal may obtain the first configuration information based on indication signaling. For example, the indication signaling may be the indication signaling in the first cell, or the indication information may be the indication signaling in a cell other than the first cell, or the indication signaling may be the indication information sent by the network device of the first cell, or the indication information may be the indication signaling sent by a network device other than the network device of the first cell. Among them, the indication signaling may be a broadcast signaling or a unicast signaling. The present disclosure does not limit this.

[0228] In some embodiments, the terminal may obtain first configuration information in a first cell. For example, the network device may carry the first configuration information in the Master Information Block (MIB) or Downlink Control Information (DCI) in the first cell. Among them, 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 by a System Information - Radio Network Temporary Identifier (SI-RNTI).

[0229] In some embodiments, the terminal may obtain the first configuration information in other cells outside the first cell. For example, the terminal may 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 the first configuration information in the first cell. If the first configuration cannot be obtained in the first cell, the terminal may attempt to obtain the first configuration information in the second cell. Among them, after the terminal obtains the first configuration information in the second cell, the terminal may send a request message in the first cell according to the first configuration information.

[0231] In some embodiments, the type of the first cell includes one of the following:

[0232] A cell that supports network energy saving;

[0233] A cell that does not support network energy saving;

[0234] A cell that supports sending the first information based on an on-demand mode;

[0235] A cell that does not support sending the first information based on an on-demand mode;

[0236] A cell that sends the first information based on an on-demand mode;

[0237] A cell that does not send the first information based on an on-demand mode.

[0238] In some embodiments, the terminal may determine the content indicated by the second indication information according to whether the first configuration information is obtained (in this case, the second indication information is an implicit indication). For example, when the terminal obtains the first configuration information, it may determine that the second indication information indicates a part of the type of the first cell. When the terminal fails to obtain the first configuration information, it may 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 according to the type of the first cell includes at least one of the following:

[0240] Determine that the first cell is in a prohibited state in response to the first cell being a cell that does not support network energy saving, and / or a cell that does not support sending the first information based on the on-demand mode, and / or a cell that does not send the first information based on the on-demand mode;

[0241] Determine that the first cell is in an unprohibited state in response to the first cell being a cell that supports network energy saving, and / or a cell that supports sending the first information based on the on-demand mode, and / or a cell that sends the first information based on the on-demand mode;

[0242] Determine that the first cell is in an unprohibited state in response to the first cell being a cell that supports network energy saving, and / or a cell that supports sending the first information based on the on-demand mode, and / or a cell that sends the first information based on the on-demand mode, and the terminal obtains the first configuration information;

[0243] Determine that the first cell is in a prohibited state in response to the first cell being a cell that supports network energy saving, and / or a cell that supports sending the first information based on the on-demand mode, and / or a cell that sends the first information based on the on-demand mode, and the terminal fails to obtain the first configuration information;

[0244] Determine that the first cell is in a prohibited state within a first time period in response to the first cell being a cell that supports network energy saving, and / or a cell that supports sending the first information based on the on-demand mode, and / or a cell that sends the first information based on the on-demand mode, and the terminal fails to obtain the first configuration information. Determine that the state of the first cell changes to an unprohibited state in response to the terminal obtaining the first configuration information within the first time period.

[0245] In some embodiments, for the sake of simplicity of description, a cell that does not support network energy saving, and / or a cell that does not support sending the first information based on the on-demand mode, and / or a cell that does not send the first information based on the on-demand mode may be described as the first cell being of a first type; and a cell that supports network energy saving, and / or a cell that supports sending the first information based on the on-demand mode, and / or a cell that sends the first information based on the on-demand mode may be described as the first cell being of a second type.

[0246] For example, when the terminal fails to obtain the first piece of information in the first cell, the terminal can determine the type of the first cell. If the first cell belongs to the first type, it can be determined that the first cell has not received the first piece of information of the first cell, which is not caused by the first cell supporting NES (for example, because the network device is in the NES mode and stops sending the first piece of information), and / or, not caused by the first cell supporting the on-demand mode of sending the first piece of information (for example, because the network device is in the NES mode and the first piece of information is in the on-demand mode), and / or, not caused by the first cell sending the first piece of information based on the on-demand mode (for example, the first piece of information in the first cell stops being sent because it is in the on-demand mode). Then, most likely, it is because the signal quality of the first cell is very poor for the terminal, resulting in the terminal failing to receive the first piece of information in the first cell. Therefore, it can be determined that the first cell is in a prohibited state.

[0247] For example, when the terminal fails to obtain the first piece of information in the 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 cell has not received the first piece of information of the first cell, which may be caused by the first cell supporting NES (for example, because the network device is in the NES mode and stops sending the first piece of information), and / or, may be caused by the first cell supporting the on-demand mode of sending the first piece of information (for example, because the network device is in the NES mode and the first piece of information is in the on-demand mode), and / or, may be caused by the first cell sending the first piece of information based on the on-demand mode (for example, the first piece of information in the first cell stops being sent because it is in the on-demand mode), rather than because the signal quality of the first cell is very poor for the terminal, resulting in the terminal failing to receive the first piece of information in the first cell. Therefore, it can be determined that the first cell is in an unprohibited state.

[0248] In some embodiments, when the terminal determines that the type of the first cell is the first type, it can determine that the first cell is in a prohibited 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 (for example, 300 seconds). For example, this period of time can be referred to as the first duration, and the first duration can be agreed upon by the protocol, or, can be indicated by the network device, or, can be determined based on the terminal capabilities. The terminal will not consider the first cell when performing cell selection or cell reselection within the first duration.

[0249] In some embodiments, when the terminal determines that the type of the first cell is the second type, it may determine that the first cell is not prohibited. In this case, the terminal may choose to send a request message in the first cell according to the first configuration information to request the network device to send the first information in the first cell; the terminal may 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, when the terminal determines that the type of the first cell is the second type, it may further determine whether the terminal has obtained the first configuration information. If the terminal has obtained the first configuration information, it may determine that the first cell is not prohibited. If the terminal fails to obtain the first configuration information, it may determine that the first cell is prohibited.

[0251] In some embodiments, when the terminal determines that the type of the first cell is the second type and fails to obtain the first configuration information, it may determine that the first cell is prohibited first and exclude the first cell from the candidate cells for cell selection and cell reselection for a period of time. For example, this period of time may be referred to as the first duration.

[0252] Within the first duration, 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 duration, then the first cell remains prohibited; if the terminal obtains the first configuration information within the first duration, it may determine that the state of the first cell changes to not prohibited, and thus may determine that the first cell belongs to the candidate cells for cell selection and cell reselection.

[0253] In some embodiments, when the terminal determines that the type of the first cell is the second type and obtains the first configuration information, it may send a request message to the network device according to the first configuration information to request the network device to send the first information. After the terminal sends the request message to the network device, it may attempt to receive the first information in the first cell and determine the state of the first cell according to whether the first information is received within the second duration.

[0254] For example, if the first information is periodic information, the second duration may include N periods of the first information, where it may be agreed by the protocol, or indicated by the network device, or determined based on the terminal capabilities.

[0255] After the terminal sends a request message to the network device, it can attempt to receive the first information in the first cell and determine whether the first information is received within the period of N pieces of first information. If the terminal receives the first information within the period of N pieces of first information, it can determine that the first cell is in an unrestricted state. If the terminal does not receive the first information within the period of N pieces of first information, it can determine that the first cell is in a prohibited state.

[0256] In some embodiments, the type of the first cell is determined based on at least one of the following:

[0257] The second indication information of the network device;

[0258] The identifier of the first cell;

[0259] The frequency band where the first cell is located.

[0260] In some embodiments, the type of the first cell can be determined based on a predefined rule, or can be indicated by the network device. For example, the network device can send the second indication information to the terminal, and the second indication information is used to indicate the type of the first cell to the terminal.

[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] The scrambling sequence of the Physical Broadcast Channel.

[0265] For example, the spare bit in the MIB can be used as the second indication information.

[0266] For example, the reserved bit in the PBCH can be used as the second indication information. Regarding the reserved bit in the PBCH, reference can be made to the previous embodiments. The implementation manner of the second indication information is similar to that of the first indication information in this regard, and will not be elaborated here.

[0267] For example, the 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, reference can be made to the previous embodiments. The implementation manner of the second indication information is similar to that of the first indication information in this regard, and will not be elaborated here.

[0268] In some embodiments, when the type of the first cell is specified based on a predefined rule, the predefined rule may include determining whether the identifier of the first cell belongs to an identifier set, and / or determining whether the frequency band where the first cell is located belongs to a frequency band set.

[0269] In some embodiments, in response to the identifier of the first cell belonging to the identifier set, it is determined that the first cell is a cell supporting network energy saving; and / or,

[0270] In response to the identifier of the first cell belonging to the identifier set, it is determined that the first cell is a cell supporting the transmission of the first information in an on-demand mode; and / or,

[0271] In response to the identifier of the first cell not belonging to the identifier set, it is determined that the first cell is a cell not supporting network energy saving; and / or,

[0272] In response to the identifier of the first cell not belonging to the identifier set, it is determined that the first cell is a cell not supporting the transmission of the first information in an on-demand mode; and / or,

[0273] In response to the frequency band where the first cell is located belonging to the frequency band set, it is determined that the first cell is a cell supporting network energy saving; and / or,

[0274] In response to the frequency band where the first cell is located belonging to the frequency band set, it is determined that the first cell is a cell supporting the transmission of the first information in an on-demand mode; and / or,

[0275] In response to the frequency band where the first cell is located not belonging to the frequency band set, it is determined that the first cell is a cell not supporting network energy saving; and / or,

[0276] In response to the frequency band where the first cell is located not belonging to the frequency band set, it is determined that the first cell is a cell not supporting the transmission of the first information in an on-demand mode.

[0277] In some embodiments, the terminal may determine the type of the first cell according to whether the identifier of the first cell belongs to the identifier set. For example, in the case where it is determined that the identifier of the first cell does not belong to the identifier set, it may be determined that the first cell is of the first type, that is, the first cell is a cell not supporting network energy saving, and / or, a cell not supporting the transmission of the first information in an on-demand mode, and / or, a cell not transmitting the first information in an on-demand mode. In the case where it is determined that the identifier of the first cell belongs to the identifier set, it may be determined that the first cell is of the second type, that is, the first cell is a cell supporting network energy saving, and / or, a cell supporting the transmission of the first information in an on-demand mode, and / or, a cell transmitting the first information in an on-demand mode.

[0278] In some embodiments, the second duration in the above embodiments may be associated with the cell. For example, the second durations corresponding to different cells may be different or the same.

[0279] It should be noted that the identifier set may be predefined or indicated by the network device, and the present disclosure does not limit this.

[0280] In some embodiments, the terminal may determine the type of the first cell based on whether the frequency band of the first cell belongs to a set of frequency bands. For example, in the case where it is determined that the frequency band of the first cell does not belong to the set of frequency bands, the first cell may be determined to be of the first type, that is, the first cell is a cell that does not support network energy saving, and / or is a cell that does not support sending the first information based on the on-demand mode, and / or is a cell that does not send the first information based on the on-demand mode. In the case where it is determined that the frequency band of the first cell belongs to the identification set, the first cell may be determined to be of the second type, that is, the first cell is a cell that supports network energy saving, and / or is a cell that supports sending the first information based on the on-demand mode, and / or is a cell that sends the first information based on the on-demand mode.

[0281] In some embodiments, the second duration in the above embodiments may be associated with the frequency band. For example, the second durations corresponding to different frequency bands may be different or the same.

[0282] It should be noted that the set of frequency bands may be predefined or indicated by a network device, and the present disclosure does not limit this.

[0283] In some embodiments, considering that the network device mainly determines whether to notify the sending of the first information based on the number of accessed terminals and service conditions, etc., for example, sending the first information on demand. Exemplarily, if during non-working hours, the number of accessed terminals is relatively small and the service demand is relatively small, the network device stops sending the first information and sends the first information after receiving the request information; correspondingly, if during working hours, the number of accessed terminals is relatively large and the service demand is relatively large, the network device sends the first information based on the normal mode (for example, sending the first information according to the configuration information of the first information). Therefore, the cell type may change over different times.

[0284] On this basis, in some embodiments, when the terminal determines that the first cell is of the second type according to the identification of the first cell belonging to the identification set, it may be determined that the first cell is of the second type within a period of time t, and the first cell is of the first type outside the time t.

[0285] In some embodiments, when the terminal determines that the first cell is of the second type according to the frequency band of the first cell belonging to the set of frequency bands, it may be determined that the first cell is of the second type within a period of time t, and the first cell is of the first type outside the time t.

[0286] The communication method involved in the embodiments of the present disclosure may include at least one of step S201 to step S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and step S201 + S202 may be implemented as an independent embodiment, but not limited thereto.

[0287] In some embodiments, steps S201 and S202 may be executed in a swapped order or simultaneously.

[0288] In some embodiments, step S201 is optional, and in different embodiments, one or more of these steps may be omitted or replaced.

[0289] In some embodiments, step S202 is optional, and in different embodiments, one or more of these steps may be omitted or replaced.

[0290] In some embodiments, reference may be made to Figure 2 other optional implementation manners described before or after the corresponding specification.

[0331] For a second aspect, alternative implementation manners of alternative embodiments of the second aspect can be referred to Figure 2 the alternative implementation manners in the illustrated embodiments, and Figure 2 other related parts in the related embodiments are not elaborated herein.

[0332] In some embodiments, when a terminal supporting network energy saving receives indication information and determines that it cannot obtain SIB1, the corresponding cell state. Correspondingly, the network device transmits indication information for the terminal to determine the corresponding cell state when it cannot obtain SIB1. As follows, the present invention scheme elaborates specific invention schemes based on different indication information;

[0333] Embodiment 1.1: The indication information is indicated based on reserved bits carried by the MIB and / or PBCH.

[0334] Based on different SSB patterns and frequency domain ranges, the reserved bits carried by the PBCH are shown in Table 3 below:

[0335]

[0336] Table 3

[0337] Exemplarily, in the FR1 licensed scenario, the reserved bits carried by the PBCH are

[0338]

[0339] Exemplarily, the indication information is based on the bits carried by the PBCH or Bit indication.

[0340] Exemplarily, the indication information is based on the spare bit indication in the MIB.

[0341] Exemplarily, in the FR1 scenario, the indication information is based on the bit or bit indication carried by the PBCH; in the FR2 scenario, the indication information is based on the spare bit indication in the MIB.

[0342] Exemplarily, in the FR1 scenario, the indication information is based on the bit or bit indication carried by the PBCH; in the FR2 scenario, the indication information is determined based on the scrambling method of the PBCH. For the specific scrambling method, see Embodiment 1.2.

[0343] Exemplarily, when the indication information indicates a first value, e.g., the indication is 0, the terminal determines that the cell is in the 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. Exemplarily, the first time length is equal to 300 s. Within the first time length, the terminal will not select to camp on the current cell;

[0344] Exemplarily, when the indication information indicates a second value, e.g., the indication is 1, the terminal determines that the cell is in the not barred state and includes the cell in the cell selection / reselection candidate cell range;

[0345] Exemplarily, if the terminal determines that the cell is in the not barred state and under the condition that the terminal obtains the first configuration information, the terminal sends a trigger message to trigger the network device to send SIB1 and attempts to receive SIB1. The first configuration information is based on the above definition and will not be elaborated here; correspondingly, if the network device receives the trigger message, it can start transmitting SIB1.

[0346] Embodiment 1.2: The indication information is indicated based on the PBCH scrambling method.

[0347] Exemplarily, the indication method is determined based on the v value of the PBCH scrambling sequence. For users supporting network energy saving, if the v value belongs to the first value set, the terminal determines that the cell is in the barred state; if the v value belongs to the second value set, the terminal determines that the cell is in the not barred state;

[0348] Exemplarily, the first value set shown is {0, 1}, and the second value set is {2, 3}, and the corresponding v value is determined based on the 2nd and 3rd of the SFN. It is determined that the corresponding relationship is as shown in Table 1 above.

[0349] Exemplarily, the first value set shown is {0, 1, 2, 3}, and the second value set is {4, 5, 6, 7}, and the corresponding v value is determined based on the half-frame indication bit, i.e., and the 2nd and 3rd LSBs of the SFN. The corresponding relationship is as shown in Table 2 above.

[0350] Exemplarily, the indication method is determined based on the initial value of the PBCH scrambling sequence. Exemplarily, if the first m-sequence x corresponding to the PBCH scrambling sequence 1 (n) The initial value is determined based on the following method, x 1 (0) = 1, x 1 (n) = 0, n = 0, 1, 2, …, 30, the terminal determines that the cell is in the barred state; if x 1 (n) The initial value is determined based on the following method, x 1 (1) = 1, x 1 (n) = 0, n = 0, 2, 3, …, 30, the terminal determines that the cell is not in the barred state.

[0351] Exemplarily, if the terminal determines that the cell is in the barred state and excludes the cell from the cell selection / reselection candidate cell range for the first time length, the first time length is determined based on a predefined method, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300 s. Within the first time length, the terminal will not select to camp on the current cell;

[0352] Exemplarily, when the terminal determines that the cell is in the not barred state and under the condition that the terminal obtains the first configuration information, the terminal sends a trigger message to trigger the network device to send SIB1 and attempts to receive SIB1. The first configuration information is based on the above definition and will not be elaborated here; correspondingly, if the network device receives the trigger message, it can start transmitting SIB1.

[0353] Embodiment 1.3: The terminal determines the state of the current cell based on whether it obtains the first configuration information corresponding to the current cell.

[0354] Exemplarily, the configuration information is used for the terminal to send a trigger message to trigger the transmission of cell system information; Exemplarily, the configuration information may be a WUS configuration, and the trigger message may be a WUS. The terminal may obtain the first configuration information based on other cell indication information, or based on the current cell indication information, or based on a predefined manner. The present invention does not limit this.

[0355] Exemplarily, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines that it can obtain the corresponding SIB1 based on the method of sending WUS. The terminal determines that the cell is in the not barred state, the terminal sends WUS, triggers the network device to send SIB1, and attempts to receive SIB1; Correspondingly, if the network device receives the trigger message, it can start transmitting SIB1.

[0356] Exemplarily, if the terminal does not obtain 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 the barred state, and excludes the cell from the cell selection / reselection candidate cell range for a first time length, where the first time length is determined based on a predefined manner, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300 s. During the first time length, the terminal will not choose to camp on the current cell;

[0357] Exemplarily, if the terminal does not obtain 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 the barred state, and tentatively excludes the cell from the cell selection / reselection candidate cell range for a first time length, where the first time length is determined based on a predefined manner, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300 s. During the first time length,

[0358] 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;

[0359] if the terminal obtains the WUS configuration corresponding to the current cell within the first time length, the terminal updates the current cell state to the not barred state, the terminal sends WUS, triggers the network device to send SIB1, and attempts to receive SIB1; Correspondingly, if the network device receives the trigger message, it can start transmitting SIB1.

[0360] Exemplarily, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines whether the cell is in the barred state based on a second condition, specifically including:

[0361] After the terminal sends a WUS, if it still fails to obtain SIB1 information after N SIB1 configuration cycles, it is determined that the cell is in the barred state; otherwise, the terminal determines that the cell is in the not barred state.

[0362] After the terminal sends a WUS, if it fails to obtain SIB1, the terminal continues to send a WUS. After N WUS transmissions, if it still fails to obtain SIB1 information, it is determined that the cell is in the barred state; otherwise, the terminal determines that the cell is in the not barred state.

[0363] The N is determined based on a predefined value, signaling configuration, or predefined method.

[0364] In some embodiments, a 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.

[0365] Embodiment 2.1: A terminal supporting network energy saving determines the cell type based on indication information and, based on the cell type, determines the corresponding cell state when SIB1 cannot be obtained.

[0366] Correspondingly, the network device sends indication information for indicating the corresponding cell type.

[0367] Exemplarily, the indication information is indicated based on reserved bits of the MIB and / or PBCH. For the specific indication method, refer to Embodiment 1.1 and details are not described herein again.

[0368] Exemplarily, the indication information is indicated based on the PBCH scrambling method. For the specific indication method, refer to Embodiment 1.2 and details are not described herein again.

[0369] Exemplarily, the indication information is indicated based on whether WUS configuration is obtained. For the specific indication method, refer to Embodiment 1.3 and details are not described herein again.

[0370] Exemplarily, if the indication information indicates that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand mode for sending system information, when the terminal cannot obtain SIB1, the terminal determines that the cell is in the not barred state and includes the cell in the cell selection / reselection candidate cell range.

[0371] Exemplarily, when the terminal determines that the cell is in the not barred state and under the condition that the terminal obtains the first configuration information, the terminal sends a trigger message to trigger the network device to send SIB1 and attempts to receive SIB1. The first configuration information is defined as above and details are not described herein again. Correspondingly, if the network device receives the trigger message, it can start transmitting SIB1.

[0372] Exemplarily, if the terminal determines that the cell is in the not barred state and the terminal has not obtained the first configuration information, the terminal searches for other cells and attempts to receive the system information of other cells to obtain the first configuration information corresponding to the current cell.

[0373] Exemplarily, if the indication information indicates that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand mode of sending system information, when the terminal is unable to obtain SIB1, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines that the cell is in the not barred state and includes the cell within the range of cell selection / reselection candidate cells;

[0374] Exemplarily, if the indication information indicates that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand mode of sending system information, when the terminal is unable to obtain SIB1, if the terminal has not obtained the WUS configuration corresponding to the current cell, the terminal determines that the cell is in the barred state and excludes the cell from the range of cell selection / reselection candidate cells for a first time length, where the first time length is determined based on a predefined manner, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300 s. Within the first time length, the terminal will not choose to camp on the current cell;

[0375] Exemplarily, if the indication information indicates that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand mode of sending system information, when the terminal is unable to obtain SIB1, if the terminal has not obtained the WUS configuration corresponding to the current cell, the terminal determines that it is unable to obtain the corresponding SIB1 based on the way of sending WUS. The terminal determines that the cell is in the barred state and tentatively excludes the cell from the range of cell selection / reselection candidate cells for a first time length, where the first time length is determined based on a predefined manner, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300 s. Within the first time length,

[0376] if the terminal has not obtained the WUS configuration corresponding to the current cell, the terminal will not choose to camp on the current cell;

[0377] If the terminal obtains the WUS configuration corresponding to the current cell within the first time length, the terminal updates the current cell state to the not barred state, includes the cell in the cell selection / reselection range, the terminal 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.

[0378] Embodiment 2.2: The terminal supporting network energy saving determines the cell type based on a predefined method. And based on the cell type, when it is determined that SIB1 cannot be obtained, the corresponding cell status is determined.

[0379] Exemplarily, the terminal determines whether the cell is a cell supporting network energy saving and / or a cell supporting system information transmission in an on-demand mode based on whether the cell ID belongs to the first set. That is, if the cell ID belongs to the first set, the terminal determines that the cell is a cell supporting network energy saving and / or a cell supporting system information transmission in an on-demand mode, and vice versa;

[0380] Exemplarily, the terminal determines whether the cell is a cell supporting network energy saving and / or a cell supporting system information transmission in an on-demand mode 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 is a cell supporting network energy saving and / or a cell supporting system information transmission in an on-demand mode, and vice versa;

[0381] Exemplarily, the first set is determined based on signaling indication or a predefined method;

[0382] In one scenario, considering that the network device mainly determines whether to send system information on demand based on the number of access users and service conditions, etc. Exemplarily, during non-working hours, when the number of corresponding access users is relatively small and the service demand is relatively small, the network device stops sending system information and sends system information after receiving a trigger message; correspondingly, during working hours, when the number of corresponding access users is relatively large and the service demand is relatively large, the network device sends system information based on the normal mode. Therefore, the cell type may change with different times.

[0383] Based on the above background, in another possible implementation manner, within the first time period range, the terminal determines whether the cell is a cell supporting network energy saving and / or a cell supporting system information transmission in an on-demand mode based on whether the cell ID belongs to the first set. That is, if the cell ID belongs to the first set, the terminal determines that the cell is a cell supporting network energy saving and / or a cell supporting system information transmission in an on-demand mode, and vice versa;

[0384] Outside the first time period range, the terminal determines that the cell is a cell not supporting network energy saving and / or a cell not sending system information based on the on-demand mode;

[0385] Based on the above background, in another possible implementation, within the first time period, the terminal determines whether the cell is a cell supporting network energy saving and / or a cell supporting on-demand mode of transmitting system information based on whether the band to which the cell belongs belongs to the first set. That is, if the band to which the cell belongs belongs to the first set, the terminal determines that the cell is a cell supporting network energy saving and / or a cell supporting on-demand mode of transmitting system information, and vice versa;

[0386] Outside the first time period, the terminal determines that the cell is a cell not supporting network energy saving and / or a cell not transmitting system information based on the on-demand mode;

[0387] Exemplarily, the second time period is determined based on signaling indication or a predefined manner, and the second time period can be in units of h, minute, s, frame, sub-frame, time slot, OFDM symbol, etc.; Exemplarily, the second time periods corresponding to different cell IDs or cell ID groups can be the same or different;

[0388] Exemplarily, the first set is determined based on signaling indication or a predefined manner;

[0389] Exemplarily, if the terminal determines based on a predefined manner that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand mode of transmitting system information, when the terminal cannot obtain SIB1, the terminal determines that the cell is in the notbarred state and includes the cell in the cell selection / reselection candidate cell range;

[0390] Exemplarily, when the terminal determines that the cell is in the not barred state, under the condition that the terminal obtains the first configuration information, the terminal sends a trigger message to trigger the network device to send SIB1 and attempts to receive SIB1. The first configuration information is based on the above definition and will not be elaborated here; Correspondingly, if the network device receives the trigger message, it can start transmitting SIB1.

[0391] Exemplarily, when the terminal determines that the cell is in the not barred state, under the condition that the terminal does not obtain the first configuration information, the terminal searches for other cells and attempts to receive the system information of other cells to obtain the first configuration information corresponding to the current cell.

[0392] Exemplarily, if the terminal determines based on a predefined manner that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand mode of transmitting system information, 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 the not barred state and includes the cell in the cell selection / reselection candidate cell range;

[0393] Exemplarily, if the terminal determines, based on a predefined manner, that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand mode transmission of system information, when the terminal fails to obtain SIB1 and has not obtained 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, which is determined based on a predefined manner, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300 s. Within the first time length, the terminal will not choose to camp on the current cell;

[0394] Exemplarily, if the terminal determines, based on a predefined manner, that the cell type is a cell supporting network energy saving and / or a cell supporting on-demand mode transmission of system information, when the terminal fails to obtain SIB1 and has not obtained the WUS configuration corresponding to the current cell, the terminal determines that it is unable to obtain the corresponding SIB1 based on the method of sending WUS. The terminal determines that the cell is in a barred state and tentatively excludes the cell from the cell selection / reselection candidate cell range for a first time length, which is determined based on a predefined manner, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300 s. Within the first time length,
