[0097] In the above embodiment, for the secondary cell supporting the network energy saving (NES) mode in the carrier aggregation scenario, the SIB of the second cell can be used to determine whether the cell allows or prohibits terminal selection and / or reselection, so that the secondary cell is invisible to terminals in a non-connected state in the second cell (such as the main cell) (such as existing terminals and terminals that do not support requesting SSB and / or SIB1, or may also include terminals that support requesting SSB and / or SIB1). That is, when the cell is selected and / or reselected, the existing terminals in a non-connected state in the second cell (such as the main cell) and the terminals that do not support requesting SSB and / or SIB1 cannot be selected or reselected to the secondary cell, thereby avoiding the existing (legacy) terminals from residing in the cell as a normal cell, ensuring that the terminals residing in the cell should be terminals that support requesting SSB and / or SIB1, thereby ensuring normal communication between the terminal and the network.

[0100] In the above embodiment, for the secondary cell supporting the network energy saving (NES) mode in the carrier aggregation scenario, the first frequency list in the SIB of the second cell (such as InterFreqCarrierFreqList in SIB4) can be used to determine whether the cell allows or prohibits terminal selection and / or reselection, so that the secondary cell is invisible to terminals in a non-connected state in the second cell (such as the main cell) (such as existing terminals and terminals that do not support requesting SSB and / or SIB1, or may also include terminals that support requesting SSB and / or SIB1). That is, during cell selection and / or reselection, existing terminals in a non-connected state in the second cell (such as the main cell) and terminals that do not support requesting SSB and / or SIB1 cannot be selected or reselected to the secondary cell, thereby avoiding existing (legacy) terminals from residing in the cell as a normal cell, ensuring that the terminals residing in the cell should be terminals that support requesting SSB and / or SIB1, thereby ensuring normal communication between the terminal and the network.

[0101] In combination with some embodiments of the third aspect, in some embodiments, the SIB further includes a second frequency list, and the second frequency list is used for cell selection and / or reselection.

[0158] In some embodiments, the first network device 102 may be a network device associated with a first cell in this document, wherein the first network device being associated with the first cell may mean that the first network device sends and / or receives information or signals within the first cell.

[0159] In some embodiments, the first cell in this document may be a secondary cell (SCell) in a carrier aggregation scenario (such as an inter-band CA scenario), and the SCell is a Network Energy Saving cell (NES cell). In some embodiments, the first cell in this document supports sending SSB and / or SIB1 (System Information Block type 1) based on request. Exemplarily, the first cell may send SSB (on demand SSB) and / or SIB on demand, which may be used as an enhancement to SSB transmission for scenarios not covered by SSB-less operation to achieve network element gain and ensure appropriate / enhanced SCell functions, including time / frequency synchronization, L1 / L3 measurement and SCell activation. If the terminal needs to obtain the SSB of the above-mentioned first cell (i.e., the SCell that supports sending SSB based on request, also called on-demand SSBSCell), it may use the UL WUS (wakeup signal) wake-up signal to request the SSB from the first cell.

[0160] In some embodiments, the second network device 103 may be a network device associated with the second cell herein. The association of the second network device with the second cell may mean that the second network device transmits and / or receives information or signals within the second cell. The second cell is a neighboring cell of the first cell. Exemplarily, the second cell and the first cell have overlapping coverage or adjacent coverage, i.e., the second cell and the first cell are neighbors.

[0161] In some embodiments, the first network device 102 and the second network device 103 herein may be the same network device or different network devices. In some embodiments, the first network device 102 may be an access network device. The second network device 103 may also be an access network device.

Exemplarily, an R19 version UE does not support a terminal that requests SSB and / or SIB1, and the terminal does not support waking up the above-mentioned first cell through WUS to send SSB and / or SIB1.

[0166] In some embodiments, 101 herein may be, for example, a second-category terminal. The second-category terminal may refer to a terminal that supports requesting SSB and / or SIB1. For example, a terminal that supports requesting SSB and / or SIB1 refers to an R19 version UE that supports requesting SSB and / or SIB1.

[0167] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0168] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0169] The embodiments of the present disclosure 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), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (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 utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0170] It's important to note that with the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, the 3GPP (3rd Generation Partnership Project) international standards organization has begun developing 5G. The main application scenarios for 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). eMBB continues to focus on providing users with multimedia content, services, and data, and demand for it is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly, making a generalized approach difficult and requiring detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. mMTC's key features include high connection density, low data volumes, latency-insensitive services, low module costs, and a long service life.

[0171] Since the energy consumption of 5G base stations is four times that of LTE base stations, network energy saving is an important means for operators to reduce the cost of operating 5G systems. In some embodiments, in order to save energy in the RRC connected state (RRC_CONNECTED) terminal, WUS (wake up signal) is introduced. An offset in front of the on duration of UE C-DRX (Connected Discontinuous Reception) defines a duration for sending a WUS signal. During this WUS duration, the WUS signal, i.e., DCI 2-6, is sent and scrambled by PS-RNTI (Power Saving RNTI) to indicate whether the terminal wakes up to monitor PDCCH (Physical Downlink Control Channel) during the next UE C-DRX onduration.

[0172] In some embodiments, a paging WUS (paging wake-up signal) is introduced to save energy in RRC_IDLE / INACTIVE terminals. This WUS, also known as the PEI (paging early indication), is sent sometime before the paging occasion (PO) to indicate whether the terminal is monitoring paging schedule information at that PO. The PEI is DCI 2-7, scrambled by the PEI-RNTI (paging early indication radio network temporary identifier).

[0173] In some embodiments, R19 NES supports FR2 and non-co-site scenarios, and on-demand SSB can be used as an enhancement to SSB transmission for scenarios not covered by SSB-less operation to achieve network element gain and ensure appropriate / enhanced SCell functions, including time / frequency synchronization, L1 / L3 measurements and SCell activation. If the terminal needs to obtain the SSB of the on-demand SSBSCell, the UL WUS wake-up signal can be used to request the SSB from the on-demand SSBSCell. For such an NES cell, if the on-demand SSBSCell / NES cell receives the request and sends an SSB, the existing (legacy) terminal happens to detect this SSB. The existing terminal may regard this cell as a normal cell and reside in it, but this cell only supports the second type of terminals mentioned above (such as terminals requesting SSB and / or SIB1), which should be barred for the existing (legacy) terminals.

[0174] That is to say, in the carrier aggregation scenario, if the on-demand SSBSCell / NES cell receives a request and sends an SSB, the existing terminal happens to detect this SSB. The existing terminal may regard this cell as a normal cell for residence, but this cell only supports request-based SSB. For the existing (legacy) terminal, it should be barred. However, for the terminal that supports request SSB and / or SIB1, it should be allowed to reside in this cell. How to prohibit the existing terminal from residing in this cell and how to indicate whether the terminal that supports request SSB and / or SIB1 is allowed to reside in this cell are issues that need to be clarified.

[0175] To this end, the embodiments of the present disclosure provide a communication method and apparatus thereof, which can solve the problems of how to prohibit existing (legacy) terminals from residing in a secondary cell (also called an on-demand SSBSCell / NES cell, or a cell supporting on-demand SSB requests) supporting the network energy saving (NES) mode in a carrier aggregation scenario, and how to indicate whether terminals supporting requesting SSB and / or SIB1 are allowed to reside in the cell. This can prevent existing (legacy) terminals from residing in the cell as a normal cell, and ensure that terminals residing in the cell should be terminals supporting requesting SSB and / or SIB1, thereby ensuring normal communication between the terminal and the network.

[0176] Figure 2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the communication method according to the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0177] In step S2101, the first network device 102 sends a Master Indication Block (MIB) in a first cell.

[0178] In some embodiments, the first cell may be a network energy-saving cell. Exemplarily, the first cell supports request-based transmission of SSB and / or SIB1. For the description of the first cell, please refer to the description of the embodiment shown in FIG1 above, which will not be repeated here.

[0179] In some embodiments, the MIB may be sent by the first network device 102 in the first cell. For example, the first network device 102 sends the MIB in the first cell, and accordingly, the terminal 101 receives the MIB sent by the first network device 102 in the first cell.

[0180] In some embodiments, the MIB can be used by terminal 101 to determine whether the first cell allows or prohibits the terminal 101 from camping. Exemplarily, after receiving the MIB, the terminal can determine, based on the MIB, whether the first cell allows or prohibits the terminal 101 from camping. In some embodiments, the terminal 101 may be a first-category terminal. The first-category terminal may refer to a legacy terminal or a terminal that does not support requesting SSB and / or SIB1.

[0181] In some embodiments, the MIB includes first indication information, which may indicate whether the first cell allows or prohibits the terminal from residing. In some embodiments, the first indication information may be a cellBarred field in the MIB. Exemplarily, the cellBarred field in the MIB may be used to indicate whether the first cell allows or prohibits the terminal from residing. In one possible implementation, the cellBarred field in the MIB is set to a first value (such as barred), indicating that the first cell prohibits the terminal from residing. In one possible implementation, the cellBarred field in the MIB of the first cell can only be set to the first value (such as barred).

[0182] Step S2102: The terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing therein based on the first indication information in the MIB.

[0183] In an embodiment of the present disclosure, terminal 101 is a first type terminal. Terminal 101 receives the MIB sent by the first network device 102 in the first cell. The MIB includes first indication information. Terminal 101 can determine whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information in the MIB.

[0184] In some embodiments, the terminal 101 is a first type terminal, and the first indication information in the MIB is a first value (such as barred), and the terminal 101 can determine that the first cell prohibits the terminal 101 from residing. In some embodiments, the first indication information can be the cellBarred (cell barred) field in the MIB. Exemplarily, the cellBarred field in the MIB can be used to indicate that the above-mentioned first cell allows or prohibits the terminal from residing. In one possible implementation, the cellBarred field in the MIB is set to a first value (such as barred) to indicate that the first cell prohibits the terminal from residing. When the terminal 101, whose terminal type is a first type terminal, receives the MIB, the terminal 101 determines that the first cell prohibits the terminal 101 from residing through the value of the cellBarred field in the MIB, that is, the terminal 101 will not reside in the first cell.

[0185] That is to say, the first indication information in the MIB of the first cell can be used to indicate that the terminal is prohibited from residing in the first cell. In this way, the terminal 101 whose terminal type is a first-category terminal receives the MIB, and through the first indication information in the MIB, it can be determined that the terminal 101 is prohibited by the first cell, and the first-category terminal will not reside in the first cell.

[0186] It is worth noting that in some embodiments, the first indication information in the MIB of the first cell is a first value. Even if a terminal supports the NES feature (or a terminal that supports requesting SSB and / or SIB1, which can also be understood as the second type of terminal in this document), it is considered to be barred from residing in the first cell. There is no additional indication information indicating whether it is not barred. In other words, this first cell (or NES cell) cannot be camped on as a primary cell and can only be a secondary cell (SCell). For example, taking the first indication information in the MIB as the cellbarred field in the MIB as an example, the cellbarred field in the MIB of the first cell is set to barred. Even if a terminal supports the NES feature (or a terminal that supports requesting SSB and / or SIB1, which can also be understood as the second type of terminal in this document), it is considered to be barred from residing in the first cell. There is no additional indication information indicating whether it is not barred. In other words, this first cell (or NES cell) cannot be camped on as a primary cell and can only be a SCell. For example, the cellBarred field in the MIB of the first cell can only be set to the first value (such as barred).

As shown in Figure 2B, the communication method according to the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0196] Step S2201: The first network device 102 sends the MIB in the first cell.

[0197] In some embodiments, the first cell may be a network energy-saving cell. Exemplarily, the first cell supports request-based transmission of SSB and / or SIB1. For the description of the first cell, please refer to the description of the embodiment shown in FIG1 above, which will not be repeated here.

[0198] In some embodiments, the MIB may be sent by the first network device 102 in the first cell. For example, the first network device 102 sends the MIB in the first cell, and accordingly, the terminal 101 receives the MIB sent by the first network device 102 in the first cell.

[0199] In some embodiments, the MIB may be used by terminal 101 to determine whether the first cell allows or prohibits the terminal 101 from camping. Exemplarily, after receiving the MIB, the terminal may determine, based on the MIB, whether the first cell allows or prohibits the terminal 101 from camping. In some embodiments, the terminal 101 may be a second-category terminal, which may refer to a terminal that supports requesting SSB and / or SIB1.

[0200] In some embodiments, the MIB includes first indication information, which may indicate whether the first cell allows or prohibits the terminal from residing. In some embodiments, the first indication information may be a cellBarred field in the MIB. Exemplarily, the cellBarred field in the MIB may be used to indicate whether the first cell allows or prohibits the terminal from residing. In one possible implementation, the cellBarred field in the MIB is set to a first value (such as barred), indicating that the first cell prohibits the terminal from residing. In one possible implementation, the cellBarred field in the MIB of the first cell can only be set to the first value (such as barred).

[0201] In some embodiments, the above-mentioned MIB may further include second indication information, and the second indication information may indicate whether the above-mentioned first cell allows or prohibits the second type of terminal from residing. Exemplarily, the MIB display may indicate whether the second type of terminal is prohibited from residing in the first cell. In one possible implementation, the second indication information may be a spare bit in the MIB, that is, the spare bit is used to indicate whether the first cell prohibits or allows the second type of terminal to reside. The terminal 101 receives the MIB sent by the first network device in the first cell, and may determine whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information and / or the second indication information in the MIB.

[0202] Step S2202: The terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information and / or the second indication information in the MIB.

[0203] In an embodiment of the present disclosure, the terminal 101 receives the MIB sent by the first network device 102 in the first cell, which includes first indication information and second indication information. The terminal 101 can determine whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information and / or second indication information in the MIB.

[0204] In some embodiments, the terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing in the first cell based on the first indication information in the MIB. Exemplarily, the terminal 101 is a first-category terminal, and the terminal 101 receives the MIB sent by the first network device 102 in the first cell, and determines that the first indication information in the MIB is a first value (such as cellBarred in the MIB is set to barred). The terminal 101 can determine that the first cell prohibits the terminal 101 from residing in the first cell, that is, the terminal 101 cannot reside in the first cell.

[0205] In some embodiments, the terminal 101 is a second-category terminal. The terminal 101 receives the MIB sent by the first network device 102 in the first cell. The terminal 101 may determine, based on the first indication information and the second indication information in the MIB, whether the first cell allows or prohibits the terminal 101 from residing. Exemplarily, the terminal 101 determines that the first indication information in the MIB is a first value (barred) and the second indication information in the MIB is a second value. The terminal 101 may determine that the first cell prohibits the terminal 101 from residing. In some embodiments, the terminal 101 is a second-category terminal. The terminal 101 receives the MIB sent by the first network device 102 in the first cell. The terminal 101 determines that the first indication information in the MIB is a first value (barred) and the second indication information in the MIB is a third value. The terminal 101 determines that the first cell allows the terminal 101 to reside.

[0206] Exemplarily, the second indication information may be a spare bit in the MIB, that is, the spare bit is used to indicate whether the first cell prohibits or allows the second type of terminal to reside. In a possible implementation, the above-mentioned second value may be 1, and the third value may be 0, that is, the second indication information in the MIB is 1, which may indicate that the first cell prohibits the second type of terminal from residing, and the second indication information in the MIB is 0, which may indicate that the first cell allows the second type of terminal to reside. Terminal 101 is a second type of terminal, and terminal 101 receives the MIB sent by the first network device 102 in the first cell. When the first indication information in the MIB is the first value (barred) and the second indication information in the MIB is 1, terminal 101 may determine that the first cell prohibits the terminal 101 from residing. When the first indication information in the MIB is the first value (barred) and the second indication information in the MIB is 0, terminal 101 may determine that the first cell allows the terminal 101 to reside.

[0207] In another possible implementation, the second value may be 0, and the third value may be 1, that is, the second indication information in the MIB is 0, which may indicate that the first cell prohibits second-category terminals from residing, and the second indication information in the MIB is 1, which may indicate that the first cell allows second-category terminals to reside. Terminal 101 is a second-category terminal, and terminal 101 receives the MIB sent by the first network device 102 in the first cell. When the first indication information in the MIB is the first value (barred) and the second indication information in the MIB is 0, terminal 101 may determine that the first cell prohibits terminal 101 from residing. When the first indication information in the MIB is the first value (barred) and the second indication information in the MIB is 1, terminal 101 may determine that the first cell allows terminal 101 to reside.

[0208] In another possible implementation, the second value may be barred, and the third value may be notbarred, that is, the second indication information in the MIB is barred, which may indicate that the first cell prohibits second-type terminals from residing, and the second indication information in the MIB is notbarred, which may indicate that the first cell allows second-type terminals to reside. Terminal 101 is a second-type terminal, and terminal 101 receives the MIB sent by the first network device 102 in the first cell. When the first indication information in the MIB is the first value (barred) and the second indication information in the MIB is barred, terminal 101 may determine that the first cell prohibits the terminal 101 from residing. When the first indication information in the MIB is the first value (barred) and the second indication information in the MIB is notbarred, terminal 101 may determine that the first cell allows the terminal 101 to reside. It should be noted that, in some embodiments, the second value and the third value may be other values, which are not limited in this disclosure and will not be described in detail. That is, terminal 101 is a second-category terminal. Terminal 101 receives the MIB sent by first network device 102 in the first cell. When determining that the first indication information in the MIB is the first value (such as the cellBarred field in the MIB is set to barred), it is necessary to additionally check the second indication information in the MIB. When the second indication information is the second value, it is determined that the first cell prohibits the terminal 101 from residing, that is, the terminal 101 cannot reside in the first cell. If the first indication information in the MIB is the first value and the second indication information in the MIB is the third value, terminal 101 can determine that the first cell allows the terminal 101 to reside, that is, the terminal 101 can reside in the first cell.

[0209] The method involved in the embodiment of the present disclosure may include at least one of step S2201 and step S2202. For example, step S2201 and step S2202 may be implemented as independent embodiments, but are not limited thereto.

[0210] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2B .

[0211] Figure 2C is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2C, the communication method according to an embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0212] Step S2301: The first network device 102 sends the MIB in the first cell.

[0213] In some embodiments, the MIB may be sent by the first network device 102 in the first cell. For example, the first network device 102 sends the MIB in the first cell, and accordingly, the terminal 101 receives the MIB sent by the first network device 102 in the first cell.

[0214] In some embodiments, the MIB may be used by the terminal 101 to determine whether the first cell allows or prohibits the terminal 101 from camping. Exemplarily, after receiving the MIB, the terminal may determine whether the first cell allows or prohibits the terminal 101 from camping based on the MIB.

[0215] In some embodiments, the MIB includes first indication information, which may indicate whether the first cell allows or prohibits the terminal from residing. In some embodiments, the first indication information may be a cellBarred field in the MIB. Exemplarily, the cellBarred field in the MIB may be used to indicate whether the first cell allows or prohibits the terminal from residing. In one possible implementation, the cellBarred field in the MIB is set to a first value (such as barred), indicating that the first cell prohibits the terminal from residing. In one possible implementation, the cellBarred field in the MIB of the first cell can only be set to the first value (such as barred).

[0216] In some embodiments, the MIB may also be used to indicate whether the first cell allows or prohibits the second type of terminal from residing. Exemplarily, a spare bit in the MIB may be used to indicate whether the first cell allows or prohibits the second type of terminal from residing. Thus, when the terminal 101 receives the MIB sent by the first network device 102 within the first cell, it may determine whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information in the MIB and / or the spare bit in the MIB.

[0217] Step S2302: The terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing therein based on the first indication information in the MIB and / or the third indication information in the MIB.

[0218] In an embodiment of the present disclosure, the terminal 101 receives the MIB sent by the first network device 102 in the first cell, and can determine whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information in the MIB and / or the third indication information in the MIB.

[0219] In some embodiments, the terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing in the first cell based on the first indication information in the MIB. Exemplarily, the terminal 101 is a first-category terminal, and the terminal 101 receives the MIB sent by the first network device 102 in the first cell, and determines that the first indication information in the MIB is a first value (e.g., cellBarred in the MIB is set to barred). The terminal 101 may determine that the first cell prohibits the terminal 101 from residing in the first cell.

[0220] In some embodiments, terminal 101 is a second type terminal. Terminal 101 receives the MIB sent by the first network device 102 in the first cell, and can determine whether the first cell allows or prohibits terminal 101 from residing based on the first indication information and the third indication information in the MIB.

[0221] In some embodiments, the third indication information may be a spare bit in the MIB, that is, the spare bit in the MIB is used to indicate whether the first cell allows or prohibits the second type of terminal from residing. Exemplarily, the presence of the third indication information indicates that the first cell prohibits the second type of terminal from residing, and the absence of the third indication information indicates that the first cell allows the second type of terminal to reside. Exemplarily, the terminal 101 is a second type of terminal, and the terminal 101 receives the MIB sent by the first network device 102 in the first cell. When the first indication information in the MIB is the first value (barred) and the third indication information exists in the MIB, the terminal 101 determines that the first cell prohibits the terminal 101 from residing. When the first indication information in the MIB is the first value (barred) and the third indication information does not exist in the MIB, the terminal 101 determines that the first cell allows the terminal 101 to reside.

[0222] In some embodiments, the presence of the third indication information indicates that the first cell allows the second type of terminal to reside, and the absence of the third indication information indicates that the first cell prohibits the second type of terminal from residing. Exemplarily, terminal 101 is a second type of terminal, and terminal 101 receives the MIB sent by the first network device 102 in the first cell. When the first indication information in the MIB is the first value (barred) and the third indication information exists in the MIB, terminal 101 determines that the first cell allows terminal 101 to reside. When the first indication information in the MIB is the first value (barred) and the third indication information does not exist in the MIB, terminal 101 determines that the first cell prohibits terminal 101 from residing.

[0223] In one possible implementation, terminal 101 is a second-category terminal. Terminal 101 receives an MIB sent by first network device 102 in a first cell. When determining that the first indication information in the MIB is a first value (e.g., the cellBarred field in the MIB is set to barred), terminal 101 further checks the third indication information in the MIB. If the third indication information exists in the MIB (i.e., the third indication information exists), terminal 101 determines that the first cell prohibits the terminal 101 from residing. If the first indication information in the MIB is a first value (barred) and the third indication information does not exist in the MIB (i.e., the third indication information is default), terminal 101 can determine that the first cell allows the terminal 101 to reside. In another possible implementation, terminal 101 is a second-category terminal. Terminal 101 receives an MIB sent by first network device 102 in a first cell. When determining that the first indication information in the MIB is a first value (e.g., the cellBarred field in the MIB is set to barred), terminal 101 further checks the third indication information in the MIB. If the third indication information exists in the MIB (i.e., the third indication information exists), terminal 101 determines that the first cell allows terminal 101 to reside. If the first indication information in the MIB is a first value (barred) and the third indication information does not exist in the MIB (i.e., the third indication information is default), terminal 101 may determine that the first cell prohibits terminal 101 from residing.

[0224] The method involved in the embodiment of the present disclosure may include at least one of step S2301 and step S2302. For example, step S2301 and step S2302 may be implemented as independent embodiments, but are not limited thereto.

[0225] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2C .

[0226] Figure 2D is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2D, the communication method according to the embodiment of the present disclosure can be applied to the communication system 100, and the method includes but is not limited to the following steps.

[0227] Step S2401: The first network device 102 sends the MIB in the first cell.

[0228] In some embodiments, the MIB may be sent by the first network device 102 in the first cell. For example, the first network device 102 sends the MIB in the first cell, and accordingly, the terminal 101 receives the MIB sent by the first network device 102 in the first cell.

[0229] The optional implementation of step S2401 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0230] Step S2402: The terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing therein based on the first indication information in the MIB and / or the first indication field in the MIB.

[0231] In an embodiment of the present disclosure, the terminal 101 receives the MIB sent by the first network device 102 in the first cell, and the MIB includes first indication information and a first indication field. The terminal 101 can determine whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information in the MIB and / or the first indication field in the MIB.

[0232] In some embodiments, the terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing in the first cell based on the first indication information in the MIB. Exemplarily, the terminal 101 is a first-category terminal, and the terminal receives the MIB sent by the first network device 102 in the first cell, and determines that the first indication information in the MIB is a first value (e.g., cellBarred in the MIB is set to barred). The terminal 101 may determine that the first cell prohibits the terminal 101 from residing in the first cell.

[0233] In some embodiments, terminal 101 is a second-category terminal. Terminal 101 receives the MIB sent by first network device 102 in the first cell and can determine whether the first cell allows or prohibits terminal 101 from residing based on the first indication information in the MIB and the first indication field in the MIB. Exemplarily, terminal 101 is a second-category terminal. The first indication information in the MIB is a first value (barred) and the value of the first indication field in the MIB satisfies a first condition. Terminal 101 determines that the first cell allows terminal 101 to reside. Terminal 101 is a second-category terminal. The first indication information in the MIB is a first value (barred) and the value of the first indication field in the MIB satisfies a second condition. Terminal 101 determines that the first cell prohibits terminal 101 from residing.

[0234] In some embodiments, the first indication field may be an SSB subcarrier offset (ssb-SubcarrierOffset) indication field in the MIB, wherein the value of the first indication field satisfies the first condition including: the value of the first indication field is within a value range of 0 to 23 in the frequency band FR1 and within a value range of 0 to 11 in the frequency band FR2. The value of the first indication field satisfies the second condition including: the value of the first indication field in the frequency band FR1 is greater than 23 and / or the value of the first indication field in the frequency band FR2 is greater than 11.

[0235] For example, the MIB can implicitly indicate that the first cell allows or prohibits the second type of terminal from residing. For example, if the K corresponding to ssb-SubcarrierOffset in the MIB is SSB If the value of is within the range of 0 to 23 in the frequency band FR1 and within the range of 0 to 11 in the frequency band FR2, it means that the first cell is not barred (not prohibited, also called allowed) for the second type of terminal (such as a terminal that supports requesting SSB and / or SIB1, which can also be understood as the second type of terminal in this article). SSB If the value of in the frequency band FR1 is greater than 23 and / or the value of the first indication field in the frequency band FR2 is greater than 11, it means that the first cell is barred for the second type of terminal (such as a terminal that supports requesting SSB and / or SIB1, which can also be understood as the second type of terminal in this article).

[0236] That is, the terminal 101 is a second type terminal, and the terminal 101 receives the MIB sent by the first network device 102 in the first cell. When it is determined that the first indication information in the MIB is the first value (such as the cellBarred field in the MIB is set to barred), it is necessary to additionally check the first indication field in the MIB. If the first indication field satisfies the first condition (such as the K corresponding to the ssb-SubcarrierOffset in the MIB), SSB If the value of is within the value range of 0 to 23 in the frequency band FR1 and within the value range of 0 to 11 in the frequency band FR2), it is determined that the first cell allows the terminal 101 to reside. If the first indication information in the MIB is the first value, the value of the first indication field in the MIB satisfies the second condition (K corresponding to ssb-SubcarrierOffset in the MIB SSB In the case where the value of is greater than 23 in the frequency band FR1 and / or the value of the first indication field is greater than 11 in the frequency band FR2), the terminal 101 may determine that the first cell prohibits the terminal 101 from residing.

[0237] The method involved in the embodiment of the present disclosure may include at least one of step S2401 and step S2402. For example, step S2401 and step S2402 may be implemented as independent embodiments, but are not limited thereto.

[0238] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2D .

[0239] Figure 2E is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2E, the communication method according to an embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0240] Step S2501: The first network device 102 sends the MIB in the first cell.

[0241] In some embodiments, the MIB may be sent by the first network device 102 in the first cell. For example, the first network device 102 sends the MIB in the first cell, and accordingly, the terminal 101 receives the MIB sent by the first network device 102 in the first cell.

[0242] The optional implementation of step S2501 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0243] Step S2502: The first network device 102 sends SIB1 in the first cell.

[0244] In some embodiments, the SIB1 may be sent by the first network device 102 in the first cell. Exemplarily, the first network device 102 sends the SIB1 in the first cell, and correspondingly, the terminal 101 receives the SIB1 sent by the first network device 102 in the first cell.

[0245] In some embodiments, the SIB1 of the first cell may indicate whether the first cell allows or prohibits the second type of terminal from residing. In some embodiments, the MIB and / or SIB1 may be used by terminal 101 to determine whether the first cell allows or prohibits the terminal 101 from residing. Exemplarily, a new IE is defined in the SIB1 of the first cell to indicate whether the first cell allows or prohibits the second type of terminal from residing. Terminal 101 receives the MIB and / or SIB1 sent by the first network device 102 in the first cell and may determine whether the first cell allows or prohibits the terminal 101 from residing based on the MIB and / or SIB1.

[0246] Step S2503: The terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing therein based on the first indication information in the MIB and / or the fourth indication information in the SIB1.

[0247] In an embodiment of the present disclosure, the terminal 101 receives the MIB and / or SIB1 sent by the first network device 102 in the first cell. The terminal 101 can determine whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information in the MIB and / or the fourth indication information in the SIB1.

[0248] In some embodiments, the terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing in the first cell based on the first indication information in the MIB. Exemplarily, the terminal 101 is a first-category terminal, and the terminal 101 receives the MIB sent by the first network device 102 in the first cell, and determines that the first indication information in the MIB is a first value (e.g., cellBarred in the MIB is set to barred). The terminal 101 may determine that the first cell prohibits the terminal 101 from residing in the first cell.

[0249] In some embodiments, terminal 101 is a second-category terminal. Terminal 101 receives the MIB and SIB1 sent by the first network device 102 in the first cell. Terminal 101 can determine whether the first cell allows or prohibits terminal 101 from residing, based on the first indication information in the MIB and the fourth indication information in the SIB1. Exemplarily, terminal 101 is a second-category terminal. The first indication information in the MIB is the first value (barred) and the fourth indication information in the SIB1 is the fourth value. Terminal 101 determines that the first cell prohibits terminal 101 from residing. Terminal 101 is a second-category terminal. The first indication information in the MIB is the first value (barred) and the fourth indication information in the SIB1 is the fifth value. Terminal 101 determines that the first cell allows terminal 101 to reside.

[0250] Exemplarily, the fourth indication information in the SIB1 may be a newly defined IE in the SIB1 of the first cell, used to indicate that the first cell allows or prohibits the second type of terminal from residing. In one possible implementation, the fourth value may be barred, and the fifth value may be notbarred, that is, the fourth indication information in the SIB1 is barred, which may indicate that the first cell prohibits the second type of terminal from residing, and the fourth indication information in the SIB1 is notbarred, which may indicate that the first cell allows the second type of terminal to residing. Terminal 101 is a second type of terminal. Terminal 101 receives the MIB sent by the first network device 102 in the first cell. If the first indication information in the MIB is the first value (barred) and the fourth indication information in the SIB1 is barred, terminal 101 may determine that the first cell prohibits the terminal 101 from residing. If the first indication information in the MIB is the first value (barred) and the fourth indication information in the SIB1 is notbarred, terminal 101 may determine that the first cell allows the terminal 101 to residing. It should be noted that the fourth value and the fifth value may also be other values, for example, the fourth value is 1 and the fifth value is 0, or the fourth value is 0 and the fifth value is 1. This disclosure does not limit this and will not elaborate on this.

[0251] That is, terminal 101 is a second-category terminal. Terminal 101 receives the MIB and SIB1 sent by the first network device 102 in the first cell. When the first indication information in the MIB is the first value (such as the cellBarred field in the MIB is set to barred), it is necessary to additionally check the indication in the SIB1. When the fourth indication information in the SIB1 is the fourth value, terminal 101 determines that the first cell prohibits the terminal 101 from residing, that is, the terminal 101 cannot reside in the first cell. If the first indication information in the MIB is the first value (barred) and the fourth indication information in the SIB1 is the fifth value, terminal 101 can determine that the first cell allows the terminal 101 to reside, that is, the terminal 101 can reside in the first cell.

[0252] The method involved in the embodiment of the present disclosure may include at least one of steps S2501 to S2503. For example, step S2501 + step S2503 may be implemented as an independent embodiment, and step S2501 + step S2502 + step S2503 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0253] In some embodiments, step S2501 and step S2502 may be executed in an interchangeable order or simultaneously.

[0254] In some embodiments, step S2502 is optional and may be omitted or replaced in different embodiments.

[0255] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2E .

[0256] Figure 2F is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2F, the communication method according to an embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0257] Step S2601: The first network device 102 sends the MIB in the first cell.

[0258] In some embodiments, the MIB may be sent by the first network device 102 in the first cell. For example, the first network device 102 sends the MIB in the first cell, and accordingly, the terminal 101 receives the MIB sent by the first network device 102 in the first cell.

[0259] The optional implementation of step S2601 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0260] Step S2602: The first network device 102 sends SIB1 in the first cell.

[0261] In some embodiments, the SIB1 may be sent by the first network device 102 in the first cell. Exemplarily, the first network device 102 sends the SIB1 in the first cell, and correspondingly, the terminal 101 receives the SIB1 sent by the first network device 102 in the first cell.

[0262] The optional implementation of step S2602 can refer to the optional implementation of step S2502 in Figure 2E and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0263] Step S2603: The terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing therein based on the first indication information in the MIB and / or the fifth indication information in the SIB1.

[0264] In an embodiment of the present disclosure, the terminal 101 receives the MIB and / or SIB1 sent by the first network device 102 in the first cell. The terminal 101 can determine whether the first cell allows or prohibits the terminal 101 from residing based on the first indication information in the MIB and / or the fifth indication information in the SIB1.

[0265] In some embodiments, the terminal 101 determines whether the first cell allows or prohibits the terminal 101 from residing in the first cell based on the first indication information in the MIB. Exemplarily, the terminal 101 is a first-category terminal, and the terminal 101 receives the MIB sent by the first network device 102 in the first cell, and determines that the first indication information in the MIB is a first value (e.g., cellBarred in the MIB is set to barred). The terminal 101 may determine that the first cell prohibits the terminal 101 from residing in the first cell.

[0266] In some embodiments, terminal 101 is a second-category terminal. Terminal 101 receives MIB and SIB1 sent by the first network device 102 in the first cell, and can determine whether the first cell allows or prohibits terminal 101 from residing based on the first indication information in the MIB and the fifth indication information in the SIB1.

[0267] In some embodiments, the fifth indication information may be a newly defined IE in the SIB1 of the first cell, used to indicate whether the first cell allows or prohibits the second type of terminal from residing. Exemplarily, the presence of the fifth indication information indicates that the first cell prohibits the second type of terminal from residing, and the absence of the fifth indication information indicates that the first cell allows the second type of terminal to reside. Exemplarily, terminal 101 is a second type of terminal, and terminal 101 receives the MIB and SIB1 sent by the first network device 102 in the first cell. The first indication information in the MIB is the first value (barred) and the fifth indication information exists in the SIB1 (i.e., the fifth indication information is present). Terminal 101 determines that the first cell prohibits terminal 101 from residing, that is, terminal 101 cannot reside in the first cell. The first indication information in the MIB is the first value (barred) and the fifth indication information does not exist in the SIB1 (the fifth indication information in the SIB1 is default). Terminal 101 determines that the first cell allows terminal 101 to reside, that is, terminal 101 can reside in the first cell.

[0268] In some embodiments, the presence of the fifth indication information indicates that the first cell allows second-category terminals to reside, and the absence of the fifth indication information indicates that the first cell prohibits second-category terminals from residing. Exemplarily, terminal 101 is a second-category terminal, and terminal 101 receives the MIB and SIB1 sent by the first network device 102 in the first cell. The first indication information in the MIB is the first value (barred) and the fifth indication information is present in the SIB1. Terminal 101 determines that the first cell allows terminal 101 to reside. The first indication information in the MIB is the first value (barred) and the fifth indication information is not present in the SIB1. Terminal 101 determines that the first cell prohibits terminal 101 from residing.

[0269] In one possible implementation, terminal 101 is a second-category terminal. Terminal 101 receives the MIB and SIB1 sent by the first network device 102 in the first cell. When determining that the first indication information in the MIB is the first value (e.g., the cellBarred field in the MIB is set to barred), terminal 101 further checks the fifth indication information in the SIB1. If the fifth indication information exists in SIB1 (i.e., the fifth indication information exists), terminal 101 determines that the first cell prohibits the terminal 101 from camping. If the first indication information in the MIB is the first value (barred) and the fifth indication information does not exist in SIB1 (i.e., the fifth indication information is default), terminal 101 can determine that the first cell allows the terminal 101 to camp. In another possible implementation, terminal 101 is a second-category terminal. Terminal 101 receives the MIB and SIB1 sent by the first network device 102 in the first cell. When determining that the first indication information in the MIB is the first value (e.g., the cellBarred field in the MIB is set to barred), terminal 101 further checks the fifth indication information in the SIB1. If the fifth indication information exists in SIB1 (i.e., the fifth indication information exists), terminal 101 determines that the first cell allows terminal 101 to reside. If the first indication information in the MIB is the first value (barred) and the fifth indication information does not exist in SIB1 (i.e., the fifth indication information is default), terminal 101 may determine that the first cell prohibits terminal 101 from residing.

[0270] The method involved in the embodiment of the present disclosure may include at least one of steps S2601 to S2603. For example, step S2601 + step S2603 may be implemented as an independent embodiment, and step S2601 + step S2602 + step S2603 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0271] In some embodiments, step S2601 and step S2602 may be executed in an interchanged order or simultaneously.

[0272] In some embodiments, step S2602 is optional and may be omitted or replaced in different embodiments.

[0273] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2F .

[0274] Figure 2G is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2G, the communication method according to an embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0275] Step S2701: The second network device 103 sends an SIB in the second cell.

[0276] In some embodiments, the second cell is a neighboring cell of the first cell. The first cell is a network energy-saving cell, and illustratively, the first cell supports request-based transmission of SSB and / or SIB1.

[0277] In some embodiments, the SIB may be sent by the second network device 103 within the second cell. Exemplarily, the second network device 103 sends the SIB within the second cell, and accordingly, the terminal 101 receives the SIB sent by the second network device 103 within the second cell. In some embodiments, the terminal 101 resides in the second cell and is in a non-connected state in the second cell, which may be an RRC IDLE state or an RRC INACTIVE state.

[0278] In some embodiments, the SIB may be used by the terminal 101 to determine whether the first cell allows or prohibits the terminal 101 from camping. Exemplarily, after receiving the SIB, the terminal may determine, based on the SIB, whether the first cell allows or prohibits the terminal 101 from camping.

[0279] Step S2702: Terminal 101 determines, based on the SIB, whether the first cell allows or prohibits terminal 101 from selecting and / or reselecting.

[0280] In an embodiment of the present disclosure, the terminal 101 receives an SIB sent by the second network device in the second cell, and can determine whether the first cell allows or prohibits the terminal 101 from residing therein based on the SIB.

[0281] In some embodiments, the first cell may be deployed according to frequency granularity. The SIB of the second cell (i.e., the SIB sent by the second network device within the second cell) may include a first frequency list, which is used for cell selection and / or reselection. The first frequency list does not include the frequency of the first cell, which may be used to indicate that the first cell prohibits terminal selection and / or reselection. Exemplarily, if the first cell is deployed according to frequency granularity (per frequency), the frequency of the first cell will not be configured in the cell selection / reselection frequency list in the SIB of the second cell. For example, the SIB may be SIB4, and the first frequency list in the SIB may be InterFreqCarrierFreqList in SIB4. The frequency of the first cell is not configured in InterFreqCarrierFreqList in SIB4, which may indicate that the first cell prohibits terminal selection and / or reselection. For a first type of terminal, it may be determined based on the InterFreqCarrierFreqList in SIB4 whether the first cell allows or prohibits the first type of terminal from selecting and / or reselecting. For the second type of terminal, an additional second frequency list can be configured in the SIB of the second cell (i.e., the SIB sent by the second network device within the second cell). This second frequency list is used for cell selection and / or reselection. This second frequency list can be used for the second type of terminal. That is, whether the second frequency list includes the frequency belonging to the first cell indicates whether the first cell allows or prohibits the second type of terminal from camping. In some embodiments, the terms "frequency list" and "frequency list" can be used interchangeably.

[0282] In some embodiments, the first cell is deployed at a frequency granularity. Terminal 101 is a first-category terminal. Terminal 101 receives an SIB sent by a second network device in the second cell. Based on the first frequency list in the SIB, Terminal 101 determines that the frequency of the first cell is not included in the first frequency list of the SIB, or that the frequency of the first cell is not configured in the first frequency list of the SIB. Terminal 101 will not select and / or reselect the first cell. In other words, the first-category terminal cannot reside in the first cell, or the first cell is not visible to the first-category terminal in the unconnected state in the second cell.

[0283] In some embodiments, the first cell is deployed at a frequency granularity. Terminal 101 is a second-category terminal. Terminal 101 receives an SIB sent by a second network device in the second cell. The SIB includes a first frequency list and a second frequency list. Terminal 101 can determine whether to allow or prohibit selection and / or reselection of the first cell based on the first frequency list and the second frequency list in the SIB. The second frequency list is used for cell selection and / or reselection.

[0284] Exemplarily, the first cell is deployed according to frequency granularity. Terminal 101 is a second-category terminal, and terminal 101 receives an SIB sent by a second network device in a second cell. If the frequency to which the first cell belongs is not included in the first frequency point list of the SIB and the frequency to which the first cell belongs is not included in the second frequency point list of the SIB, terminal 101 will not select and / or reselect to the first cell, that is, the terminal 101 cannot reside in the first cell 101. If the frequency to which the first cell belongs is not included in the first frequency point list of the SIB and the frequency to which the first cell belongs is included in the second frequency point list of the SIB, terminal 101 determines that the first cell allows the terminal 101 to select and / or reselect, that is, the terminal 101 can reside in the first cell.

[0285] In some embodiments, the first cell may be deployed at a cell granularity. The SIB of the second cell (i.e., the SIB sent by the second network device within the second cell) includes a first excluded cell list, which is used for cell selection and / or reselection. The inclusion of the first cell in the first excluded cell list may be used to indicate that the first cell is prohibited for the terminal to select and / or reselect. Exemplarily, if the above-mentioned first cell is deployed at a cell granularity (per cell), the first cell will exist in the SIB. For example, the SIB may be SIB3 / SIB4, such as the IntraFreqExcludedCellList in SIB3, and the interFreqExcludedCellList in SIB4 (InterFreqCarrierFreqInfo in SIB4). For example, the IntraFreqExcludedCellList in SIB3 and / or the interFreqExcludedCellList in SIB4 (InterFreqCarrierFreqInfo in SIB4) include the first cell, which can indicate that the first cell prohibits terminal selection and / or reselection. For the first type of terminal, it can be determined based on the IntraFreqExcludedCellList in SIB3 and / or the interFreqExcludedCellList in SIB4 whether the first cell allows or prohibits the first type of terminal from selecting and / or reselecting. For the second type of terminal, an additional cell list (such as a third cell list) can be configured in the SIB of the second cell (i.e., the SIB sent by the second network device in the second cell). The cell list is used for cell selection / reselection. The cell list is only used for the second type of terminal, indicating that the second type of terminal can reselect to the cell in the list. Exemplarily, the additional cell list (such as the second cell list) can be configured according to the frequency granularity. Exemplarily, an additional second cell list is configured for frequency 1, an additional second cell list is configured for frequency 2, and so on. Different frequencies can be configured with different second cell lists, and the cells in the second cell lists configured for different frequencies can be partially the same or completely different. For example, if the frequency to which the first cell belongs is frequency 2, the first cell will be configured in the second cell list associated with frequency 2, that is, the second cell list in the SIB of the second cell can include the second cell list associated with frequency 2.

[0286] In some embodiments, the above-mentioned first cell may be deployed at a cell granularity. Terminal 101 is a first-category terminal, and terminal 101 receives the SIB sent by the second network device in the second cell, and determines that the first cell prohibits the terminal from selecting and / or reselecting based on the fact that the first excluded cell list in the SIB includes the first cell. For example, if terminal 101 receives the IntraFreqExcludedCellList in SIB3 and / or the interFreqExcludedCellList in SIB4 (InterFreqCarrierFreqInfo in SIB4) of the second cell, which includes the above-mentioned first cell, it can be considered that the first cell prohibits the terminal 101 from selecting and / or reselecting, that is, terminal 101 will not select and / or reselect to the first cell. In other words, the first-category terminal cannot reside in the first cell, or the first cell is invisible to the first-category terminal in the non-connected state in the second cell.

[0287] In some embodiments, the first cell may be deployed at a cell granularity. Terminal 101 is a second-category terminal. Terminal 101 receives an SIB sent by a second network device in a second cell. The SIB includes a first excluded cell list and a second cell list. Terminal 101 may determine whether to select and / or reselect to the first cell based on the first excluded cell list and the second cell list in the SIB. The second cell list is used for cell selection and / or reselection. The second cell list may be configured at a frequency granularity. If the first cell is included in the first excluded cell list and the second cell list of the SIB, terminal 101 determines that the first cell allows terminal 101 to select and / or reselect, meaning that terminal 101 can select and / or reselect to the first cell. In other words, terminal 101 may camp on the first cell. If the first cell is included in the first excluded cell list and not in the second cell list of the SIB, terminal 101 determines that the first cell prohibits terminal 101 from selecting and / or reselecting, meaning that terminal 101 will not select and / or reselect to the first cell.

[0288] It is worth noting that, in some embodiments, the first cell is invisible to both the first type of terminal and the second type of terminal in the non-connected state in the second cell. Exemplarily, if the first cell can be deployed according to frequency granularity, the frequency to which the first cell belongs will not be configured in the cell selection / reselection frequency list in the SIB of the second cell. For example, the SIB can be SIB4, and the first frequency point list in the SIB can be the InterFreqCarrierFreqList in SIB4. The frequency to which the first cell belongs is not configured in the InterFreqCarrierFreqList in SIB4, which can indicate that the first cell prohibits terminal selection and / or reselection. Exemplarily, for the first type of terminal and the second type of terminal, it can be determined based on the InterFreqCarrierFreqList in SIB4 that the first type of terminal and the second type of terminal will not select and / or reselect the first cell. It is worth noting that in this embodiment, since no additional second frequency point list is configured in the SIB of the second cell, for the first and second category terminals, when receiving the SIB sent by the second network device 103 in the second cell, the first frequency point list of the SIB does not include the frequency belonging to the first cell, and no additional second frequency point list is configured in the SIB. It can be considered that the above-mentioned first cell is invisible to the first and second category terminals in the non-connected state in the second cell, that is, the first and second category terminals will not select and / or reselect to the first cell.

[0289] In some embodiments, the first cell is invisible to both the first type of terminal and the second type of terminal in the unconnected state in the second cell. Exemplarily, if the above-mentioned first cell can be deployed according to cell granularity, the first cell will exist in the SIB. For example, the SIB can be SIB3 / SIB4, such as the IntraFreqExcludedCellList in SIB3, and the interFreqExcludedCellList in SIB4 (InterFreqCarrierFreqInfo in SIB4). For example, the IntraFreqExcludedCellList in SIB3 and / or the interFreqExcludedCellList in SIB4 (InterFreqCarrierFreqInfo in SIB4) include the first cell, which can indicate that the first cell prohibits terminal selection and / or reselection. Exemplarily, for the first and second category terminals, it can be determined based on the IntraFreqExcludedCellList in SIB3 and / or the interFreqExcludedCellList in SIB4 that the first cell prohibits terminal selection and / or reselection, that is, the first and second category terminals will not select and / or reselect the first cell. It is worth noting that in this embodiment, since no additional cell list (such as a second cell list) is configured in the SIB of the second cell, for the first and second category terminals, when the SIB sent by the second network device 103 in the second cell is received, the first excluded cell list of the SIB includes the first cell, and no additional second cell list is configured in the SIB. It can be considered that the above-mentioned first cell is invisible to the first and second category terminals in a non-connected state in the second cell, that is, the first and second category terminals will not select and / or reselect to the first cell.

[0368] FIG3J is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG3J , the communication method according to an embodiment of the present disclosure can be applied to terminal 101, and the method includes but is not limited to the following steps.

[0369] Step S3110: Determine whether the first cell allows or prohibits the terminal 101 from camping on it based on the first indication information and the second indication information. The first indication information and the second indication information are used to jointly determine whether the terminal is allowed or prohibited from camping on the first cell.

[0370] In some embodiments, the terminal 101 is a second type terminal.

[0371] In some embodiments, the first indication information and the second indication information may be carried in a MIB, which may be sent by the first network device within the first cell. Exemplarily, the first network device sends the MIB within the first cell, and terminal 101, which is a second-category terminal, receives the MIB sent by the first network device within the first cell. Based on the first indication information and the second indication information in the MIB, the terminal determines whether the first cell allows or prohibits terminal 101 from camping. Exemplarily, if the first indication information in the MIB is a first value (e.g., barred) and the second indication information is a second value, it can be determined that the first cell prohibits terminal 101 from camping. If the first indication information in the MIB is a first value (e.g., barred) and the second indication information is a third value, it can be determined that the first cell allows terminal 101 to camp. The second and third values ​​can be any of 0, 1, barred, and notbarred. When the second value is 0, the third value is 1; when the second value is 1, the third value is 0; and when the second value is barred, the third value is notbarred.

[0372] Exemplarily, if the first indication information in the MIB is a first value (such as barred) and the second indication information exists in the MIB, it can be determined that the first cell prohibits the terminal 101 from residing; if the first indication information in the MIB is a first value (such as barred) and the second indication information is absent in the MIB, it can be determined that the first cell allows the terminal 101 to reside. Exemplarily, if the first indication information in the MIB is a first value (such as barred) and the second indication information exists in the MIB, it can be determined that the first cell allows the terminal 101 to reside; if the first indication information in the MIB is a first value (such as barred) and the second indication information is absent in the MIB, it can be determined that the first cell prohibits the terminal 101 from residing.

[0373] In some embodiments, the first indication information may be carried in an MIB, and the second indication information may be carried in an SIB. The MIB and SIB may be sent by the first network device within the first cell. Exemplarily, the first network device sends the MIB within the first cell, and the terminal 101, whose terminal type is a second-category terminal, receives the MIB and SIB sent by the first network device within the first cell. Based on the first indication information in the MIB and the second indication information in the SIB, it is determined whether the first cell allows or prohibits the terminal 101 from residing. Exemplarily, if the first indication information in the MIB is a first value (such as barred) and the second indication information in the SIB is a second value, it can be determined that the first cell prohibits the terminal 101 from residing; if the first indication information in the MIB is a first value (such as barred) and the second indication information in the SIB is a third value, it can be determined that the first cell allows the terminal 101 to reside. The second value and the third value can be any one of 0, 1, barred, and notbarred. When the second value is 0, the third value is 1; when the second value is 1, the third value is 0; when the second value is barred, the third value is notbarred.

[0374] Exemplarily, if the first indication information in the MIB is a first value (such as barred) and the second indication information exists in the SIB, it can be determined that the first cell prohibits the terminal 101 from residing; if the first indication information in the MIB is a first value (such as barred) and the second indication information is absent in the SIB, it can be determined that the first cell allows the terminal 101 to reside. Exemplarily, if the first indication information in the MIB is a first value (such as barred) and the second indication information exists in the SIB, it can be determined that the first cell allows the terminal 101 to reside; if the first indication information in the MIB is a first value (such as barred) and the second indication information is absent in the SIB, it can be determined that the first cell prohibits the terminal 101 from residing. Exemplarily, the SIB can be SIB1.

[0375] That is, terminal 101 is a second-category terminal. When it is determined that the first indication information is the first value, the second indication information needs to be additionally checked, and based on the second indication information, it is finally determined whether the first cell allows terminal 101 to reside.

[0411] The optional implementation of step S5201 can refer to the optional implementation of step S2701 in Figure 2G and other related parts in the embodiment involved in Figure 2G, which will not be repeated here.

[0412] Step S5202: Terminal 101 determines whether the first cell allows or prohibits terminal selection and / or reselection based on the SIB.

[0413] The optional implementation of step S5202 can refer to the optional implementation of step S2702 in Figure 2G and other related parts in the embodiment involved in Figure 2G, which will not be repeated here.

[0414] It is worth noting that the present disclosure provides a method for preventing existing terminals from staying in an NES cell (such as the first cell in this article), which solves the problem of how to prohibit existing terminals from staying in this cell and how to indicate whether terminals that support SSB requests are allowed to stay in this cell in a carrier aggregation scenario.

[0415] Solution 1: SSB is based on the cellBarred setting in the MIB of the requested cell (such as the first cell in this article) being barred.

[0416] In some embodiments, the cellBarred parameter in the MIB of the SSB-based requested cell (such as the first cell in this article) is set to barred. The above-mentioned first type of terminal is considered to be banned by this cell through the barred indicated in the MIB and will not reside in this cell.

[0417] Solution 2: The MIB of the SSB-based requesting cell (such as the first cell in this article) indicates whether the terminal supporting the SSB request (such as the second type of terminal in this article) is barred.

[0418] In some embodiments, the MIB displays an indication of whether the second type of terminal is barred, for example, through a spare bit indication, 1 indicates that the second type of terminal is barred, 0 indicates that the second type of terminal is not barred, or 1 indicates that the second type of terminal is not barred, 0 indicates that the second type of terminal is barred. Or barred indicates that the second type of terminal is barred, notbarred indicates that the second type of terminal is not barred, or through a 1-bit indication, the presence of the indication bit indicates that the second type of terminal is barred, or the presence of the bit indicates that the second type of terminal is not barred, or there are other implementation methods to indicate, which are not specifically limited in this disclosure. SSB is based on the cellBarred in the MIB of the requested cell (such as the first cell in this article) is set to barred, and the second type of terminal needs to additionally check the indication in the MIB to determine whether the second type of terminal is barred.

[0419] In some embodiments, the MIB implicitly indicates whether the second type of terminal is barred, for example, if the K corresponding to the ssb-SubcarrierOffset (SSB subcarrier offset) in the MIB is SSB The value of is 0 to 23 (FR1) and 0 to 11 (FR2), indicating that the first cell is not barred for the second type of terminal. SSB The values ​​of are >23 (FR1) and >11 (FR2), indicating that the first cell is barred for the second type of terminals.

[0420] Solution 3: SSB is based on whether the terminal supporting the requested SSB is barred as indicated in the SIB1 of the requesting cell (such as the first cell in this article).

[0421] In some embodiments, SIB1 displays an indication of whether a terminal supporting the requested SSB is barred. For example, a new IE is defined to indicate whether a second-category terminal is barred, and the value may be (barred, not barred). If the cellBarred in the MIB of the requested cell (such as the first cell in this document) is set to barred, the second-category terminal needs to additionally check the indication in SIB1 to determine whether the second-category terminal is barred.

[0422] Solution 4: The SSB-based requesting cell (such as the first cell in this article) is invisible to the terminal in the RRC IDLE / INACTIVE state in the second cell, which is a neighboring cell of the first cell.

[0423] In some embodiments, the first cell is invisible to the first type of terminal in the RRC IDLE / INACTIVE state of the second cell. If the first cell is deployed per frequency, the frequency to which the first cell belongs will not be configured in the cell selection and reselection frequency list in the SIB, such as the InterFreqCarrierFreqList in SIB4, but for terminals that support SSB requests in R19 (such as the second type of terminals in this article), an additional frequency list is configured, which is used for cell selection / reselection. This frequency list is only used for terminals that support SSB requests. If the first cell is deployed per cell, the cell will exist in the SIB, such as SIB3 / 4, such as the IntraFreqExcludedCellList in SIB3, and the interFreqExcludedCellList in SIB4 (existing in the InterFreqCarrierFreqInfo in SIB4). However, for R19 terminals that support requesting SSB, an additional cell list is configured per frequency. The cell list is used for cell selection / reselection. This cell list is only used for terminals that support requesting SSB, indicating that terminals that support requesting SSB can reselect to cells in the list.

[0424] In some embodiments, the SSB is based on the requested cell (such as the first cell in this article) and is invisible to the first type of terminal and the second type of terminal in the RRC IDLE / INACTIVE state in the second cell. If the first cell is deployed per frequency, the frequency to which the first cell belongs will not be configured in the cell selection reselection frequency list in the SIB, such as the InterFreqCarrierFreqList in SIB4. If the first cell is deployed per cell, the first cell will exist in the SIB, such as SIB3 / 4, such as the IntraFreqExcludedCellList in SIB3, and the interFreqExcludedCellList in SIB4 (stored in the InterFreqCarrierFreqInfo in SIB4).
