[0176] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. The communication system may include, but is not limited to, a terminal, a first network device, and may also include a second network device. The number and form of devices shown in Figure 1 are for example purposes only and do not limit the embodiments of the present disclosure. In actual applications, two or more terminals, two or more first network devices, and two or more second network devices may be included. The communication system 100 shown in Figure 1 includes, for example, a terminal 101, a first network device 102, and a second network device 103.

[0177] In some embodiments, the terminal 101 herein may be an entity on the user side for receiving or transmitting signals, such as a mobile phone. It may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal may be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0178] 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.

[0179] 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 refer to the second network device sending and / or receiving information or signals within the second cell. The second cell is a neighboring cell of the first cell. For example, the second cell may be a primary cell in a carrier aggregation scenario (such as an inter-band CA scenario). Exemplarily, the second cell and the first cell have overlapping coverage or adjacent coverage, i.e., the second cell and the first cell are in a neighboring cell relationship.

[0180] In some embodiments, the cells herein may be divided into first-class cells and second-class cells. In some embodiments, the first-class cells and second-class cells may be cells in a carrier aggregation scenario (such as an inter-band CA scenario), and the SCell is a Network Energy Saving cell (NES cell). The first-class cell may, for example, be a cell that supports on-demand request transmission of an SSB and / or a first SIB1, and the first-class cell supports request-based transmission of an SSB and / or SIB1 (System Information Block type 1). Exemplarily, a first-class cell (such as an on-demand SSB SCell, also called an NES cell, or named by other names, which is not limited in this disclosure) may transmit an 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-type cell (that is, the SCell that supports on-demand request to send SSB, also called on-demand SSBSCell), it can use the UL WUS (wakeup signal) wake-up signal to request the SSB from the first-type cell.

[0181] In some embodiments, the second-category cell may be a neighboring cell of the first-category cell, and the second-category cell may be, for example, a normal cell / a non-first-category cell (or a non-NES cell).

[0182] In some embodiments, the terminal 101 herein may be, for example, 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. Exemplarily, an R19 version UE that supports requesting SSB and / or SIB1 supports waking up the first cell through WUS to send SSB and / or SIB1.

[0183] 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.

[0184] In some embodiments, the access network device is, for example, a node or device that accesses a terminal device to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0185] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0186] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0187] 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.

[0188] 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.

[0189] 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).

[0190] 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.

[0191] 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.

[0192] 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).

[0193] In some embodiments, Network Energy Saving (NES) already supports SSB-less SCells in inter-band CA scenarios. SSB-less SCells do not transmit SSBs. UEs use the SSBs of the primary cell (PCell) to implement time-frequency synchronization, L1 / L3 (Layer 1 / Layer 3) measurements, and SCell activation on the SCell. However, SSB-less in inter-band CA scenarios has many limitations, such as PCell and SCell co-location and operation only in frequency band FR1. Frequency band FR2 and non-co-site scenarios are not supported.

[0194] In some embodiments, R19 NES supports FR2 and non-co-site scenarios. 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 functionality, including time / frequency synchronization, L1 / L3 measurements, and SCell activation. If a terminal needs to obtain the SSB of an on-demand SSBSCell, it can use the UL WUS wake-up signal 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, if there is no indication information, a terminal supporting on-demand SSB may select or reselect this cell as a normal cell and then initiate random access and establish an RRC connection according to the normal cell procedures. However, such an NES cell does not always send SSBs and cannot be treated as a normal cell. Additional indication information is required to indicate to the terminal supporting the R19 on-demand SSB feature that this cell is an NES cell (i.e., the SSB of this cell is sent on request).

[0195] Based on this, the embodiments of the present disclosure provide a communication method and device thereof, which can enable a terminal supporting the on-demand synchronization signal block (on demand SSB) feature to identify the first cell as a first-type cell, thereby avoiding or suspending the terminal from treating the first-type cell as a normal cell selection and / or reselection.

[0196] 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.

[0197] In step S2101, the first network device 102 sends a Master Indication Block (MIB) in a first cell.

[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 first information in the above-mentioned MIB can be used to indicate whether the first cell is a first-class cell, and the first-class cell is, for example, a cell that supports on-demand request to send an SSB and / or a first SIB1. The first SIB1 in this article can be understood as the SIB1 sent by the first-class cell. Exemplarily, the first information can be an indication field in the MIB, and a bit in the MIB of the first cell is used to indicate whether the first cell is a first-class cell (also called an on-demand SSB required cell / NES cell, also called an on-demand SSBSCell). For example, the bit in the MIB can be a spare bit (spare bit, or reserved bit). Exemplarily, it can be indicated by a 2-bit indicator bit. For example, if the first information in the MIB has a value of 1, it indicates that the corresponding first cell is a first-class cell, and if the first information in the MIB has a value of 0, it indicates that the corresponding first cell is a second-class cell (such as a normal cell / non-NES cell). Or if the first information in the MIB has a value of 0, it indicates that the corresponding first cell is a first-class cell, and if the first information in the MIB has a value of 1, it indicates that the corresponding first cell is a second-class cell. Alternatively, it may be indicated by (enable, disable). For example, if the value of the first information in the MIB is enable, it indicates that the corresponding first cell is a first-category cell. If the value of the first information in the MIB is disable, it indicates that the corresponding first cell is a second-category cell (such as a normal cell / non-NES cell). Alternatively, the first information in the MIB may be indicated by a 1-bit indication bit. For example, if the indication bit is present, it indicates that the corresponding first cell is a first-category cell. If the indication bit is defaulted, it indicates that the corresponding first cell is a second-category cell. Alternatively, if the bit is present, it indicates that the corresponding first cell is a second-category cell. If the indication bit is defaulted, it indicates that the corresponding first cell is a first-category cell. Alternatively, there may be other indication forms, which are not specifically limited in the present disclosure.

[0200] In step S2102, the terminal 101 performs cell selection or cell reselection.

[0201] In some embodiments, the candidate cells for the above-mentioned cell selection or cell reselection include the above-mentioned first cell.

[0202] In some embodiments, the terminal 101 performs cell selection or cell reselection when it determines that the cell selection or cell reselection conditions are met. The specific content of the cell selection or cell reselection conditions is not limited in this disclosure and will not be described in detail.

[0203] In step S2103 , the terminal 101 determines whether the first cell is a first type cell based on the first information in the MIB.

[0204] In some embodiments, the terminal 101 receives the MIB sent by the first network device 102 in the first cell. When the terminal 101 performs cell selection or cell reselection (or during the cell selection or cell reselection process), the terminal 101 can determine whether the first cell is the above-mentioned first type cell based on the first information in the MIB.

[0205] In some embodiments, the possible implementation methods of determining whether the first cell is the first type of cell based on the first information in the MIB may include: if the first information exists in the MIB, the first cell is determined to be the first type of cell; or if the first information does not exist in the MIB, the first cell is determined to be the second type of cell. Exemplarily, the first information may be an indication field in the MIB, and a bit in the MIB of the first cell is used to indicate whether the first cell is the first type of cell (also called an on-demand SSB required cell / NES cell). For example, the bit in the MIB may be a spare bit (or a reserved bit). The first information in the MIB is indicated by a 1-bit indication bit. For example, if the indication bit is present, it indicates that the corresponding first cell is the first type of cell, and if the indication bit is defaulted, it indicates that the corresponding first cell is the second type of cell. The terminal receives the MIB sent by the first network device 102 in the first cell, determines that the first information exists in the MIB, and can determine that the first cell is the first type of cell. If the first information does not exist in the MIB, the terminal can determine that the first cell is the second type of cell. The present disclosure does not specifically limit the naming of the first information in this embodiment, for example, ondemandSSBrequired.

[0206] In some embodiments, the possible implementation of determining whether the first cell is the first type of cell based on the first information in the MIB may include: if the first information exists in the MIB, determining that the first cell is the second type of cell; or if the first information does not exist in the MIB, determining that the first cell is the first type of cell. Exemplarily, the first information may be an indication field in the MIB, and a bit in the MIB of the first cell is used to indicate whether the first cell is a first type of cell (also called an on-demand SSB required cell / NES cell). For example, the bit in the MIB may be a spare bit (or a reserved bit). The first information in the MIB is indicated by a 1-bit indication bit. For example, if the indication bit is present, it indicates that the corresponding first cell is the second type of cell, and if the indication bit is defaulted, it indicates that the corresponding first cell is the first type of cell. The terminal receives the MIB sent by the first network device 102 in the first cell, determines that the first information exists in the MIB, and can determine that the first cell is the second type of cell. If the first information does not exist in the MIB, the terminal can determine that the first cell is the first type of cell. The present disclosure does not specifically limit the naming of the first information in this embodiment, for example, non-OndemandSSBrequired.

[0207] In some embodiments, the possible implementation methods of determining whether the first cell is the first type of cell based on the first information in the MIB may include: the first information is a first value, determining that the first cell is the first type of cell; or the first information is a second value, determining that the first cell is the second type of cell. Exemplarily, the first information may be an indication field in the MIB, and a bit in the MIB of the first cell is used to indicate whether the first cell is a first type of cell (also called an on-demand SSB required cell / NES cell). For example, the bit in the MIB may be a spare bit (or reserved bit). Exemplarily, it can be indicated by a 2-bit indicator bit. For example, if the first information in the MIB takes a value of 1, it indicates that the corresponding first cell is a first type of cell, and if the first information in the MIB takes a value of 0, it indicates that the corresponding first cell is a second type of cell (such as a normal cell / non-NES cell). Alternatively, if the first information in the MIB takes a value of 0, it indicates that the corresponding first cell is a first type of cell, and if the first information in the MIB takes a value of 1, it indicates that the corresponding first cell is a second type of cell. Alternatively, through (enable, disable) indication, for example, if the value of the first information in the MIB is enable, it indicates that the corresponding first cell is a first-category cell, and if the value of the first information in the MIB is disable, it indicates that the corresponding first cell is a second-category cell (such as a normal cell / non-NES cell). Or if the value of the first information in the MIB is enable, it indicates that the corresponding first cell is a second-category cell, and if the value of the first information in the MIB is disable, it indicates that the corresponding first cell is a first-category cell (such as a normal cell / non-NES cell).

[0208] In some embodiments, if a terminal receives an MIB sent by the first network device 102 within a first cell and determines that the first information in the MIB is a first value, the terminal may determine that the first cell is a first-category cell. If the first information in the MIB is a second value, the terminal may determine that the first cell is a second-category cell. Exemplarily, if the terminal receives an MIB sent by the first network device 102 within the first cell and determines that the first information in the MIB is 1, the terminal may determine that the first cell is a first-category cell; if the first information in the MIB is 0, the terminal may determine that the first cell is a second-category cell. Exemplarily, if the terminal receives an MIB sent by the first network device 102 within the first cell and determines that the first information in the MIB is 0, the terminal may determine that the first cell is a first-category cell; if the first information in the MIB is 1, the terminal may determine that the first cell is a second-category cell. Exemplarily, if the terminal receives an MIB sent by the first network device 102 within the first cell and determines that the first information in the MIB is enable, the terminal may determine that the first cell is a first-category cell; if the first information in the MIB is disable, the terminal may determine that the first cell is a second-category cell. Exemplarily, the terminal receives the MIB sent by the first network device 102 in the first cell, and determines that the first information in the MIB is enable, then determines that the first cell is a second-type cell; if the first information in the MIB is disable, the terminal can determine that the first cell is a first-type cell.

[0209] Step S2104: The first cell is a first type cell, and the terminal 101 determines to execute the first behavior.

[0210] In some embodiments, terminal 101 determines that the first cell is a first-category cell based on the first information, and terminal 101 may determine to execute a first behavior. That is, terminal 101 receives the MIB sent by first network device 102 within the first cell, and terminal 101 determines that the first cell is a first-category cell based on the first information in the MIB, and terminal 101 may execute the first behavior.

[0211] In some embodiments, the first behavior may include but is not limited to at least one of the following: performing cell selection or cell reselection; adjusting the cell selection or cell reselection priority of the first cell to the lowest priority. That is, when the terminal 101 performs cell selection or cell reselection (or during the cell selection or cell reselection process), if the terminal 101 determines that the first cell is a first-category cell, the terminal 101 cannot reside in the first cell and needs to continue to perform cell selection or cell reselection, or the terminal 101 may adjust the cell selection or cell reselection priority of the first cell to the lowest priority, that is, regard the first cell as the lowest priority, and avoid or suspend treating the first cell as a normal cell selection or reselection by selecting another cell or lowering the priority.

[0212] Step S2105: The first cell is a second-type cell, and the terminal 101 resides in the first cell.

[0213] In some embodiments, when the terminal 101 receives the MIB sent by the first network device 102 in the first cell and performs cell selection or cell reselection (or during cell selection or cell reselection), the terminal 101 can determine whether the first cell is the above-mentioned first type cell based on the first information in the MIB. If the terminal 101 determines that the first cell is a second type cell based on the first information in the MIB, the terminal 101 can reside in the first cell. That is, when the terminal 101 performs cell selection or cell reselection (or during cell selection or cell reselection), if the terminal 101 determines that the first cell is not a first type cell (such as the first cell is a normal cell or a non-NES cell), if it is a second type cell, the terminal 101 can reside in the first cell.

[0228] Figure 2B is an interactive diagram of a communication method according to an embodiment of the present disclosure. 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.

[0229] In step S2201, the terminal 101 performs cell selection or cell reselection.

[0230] In some embodiments, the above-mentioned cell selection or cell reselection includes the first cell.

[0231] The optional implementation of step S2201 can refer to the optional implementation of step S2102 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0232] In step S2202, the terminal 101 obtains first information, which may be a physical cell identifier (PCI) of the first cell.

[0233] In some embodiments, the first information may be used to indicate whether the first cell is a first-category cell. In some embodiments, the first-category cell is, for example, a cell that supports on-demand request transmission of an SSB and / or a first SIB1.

[0234] In some embodiments, the first information may be carried in system information, where the system information may be an SSB and / or a first SIB sent by the first network device 102 in the first cell, or the system information may be carried in an SSB and / or a first SIB sent by the first network device 102 in the first cell. Exemplarily, the system information may include a PCI used by the first cell.

[0235] In some embodiments, the above-mentioned first information may be carried in system information, wherein the system information may be an SIB sent by the second network device 103 in the second cell, or the system information may be carried in an SIB sent by the second network device 103 in the second cell. Exemplarily, the system information may include the PCI of the first cell, and the first information is associated with the PCI of the first cell, and the first information is used to indicate whether the first cell associated with the corresponding PCI is a first-class cell. Exemplarily, the second cell may be a neighboring cell of the first cell, for example, the second cell and the first cell have overlapping coverage or adjacent coverage, that is, the second cell and the first cell belong to a neighboring cell relationship. Exemplarily, the SIB sent by the second cell may be SIB3 or SIB4.

[0236] It is worth noting that the first information can also be obtained in other ways, which are not specifically limited in this disclosure and will not be described in detail. In other words, the terminal 101 can also obtain the PCI of the first cell in other ways, so that the terminal 101 can determine whether the first cell is a first-category cell based on the PCI of the first cell.

[0237] In step S2203 , the terminal 101 determines whether the first cell is a first-category cell based on the first information.

[0238] In some embodiments, the first information is the PCI of the first cell. The terminal 101 may determine whether the first cell is a first-category cell based on the PCI of the first cell.

[0239] In some embodiments, possible implementations of the terminal 101 determining whether the first cell is a first-category cell based on the first information may include: the first information is included in the PCI of the first-category cell, and the first cell is determined to be a first-category cell; or the first information is not included in the PCI of the first-category cell, and the first cell is determined to be a second-category cell. In some embodiments, the PCI of the first-category cell may be a reserved / allocated PCI, that is, it can be understood as a PCI specifically used for the first-category cell. For example, a PCI range can be reserved / allocated for the first-category cell or a PCI list can be defined for the first-category cell.

[0240] Exemplarily, the first information is the PCI of the first cell, and the terminal 101 determines that the PCI of the first cell is included in the PCI of the first type of cell, that is, the PCI of the first cell belongs to the PCI of the first type of cell, then the terminal 101 can determine that the first cell is the first type of cell. If the terminal 101 determines that the PCI of the first cell is not included in the PCI of the first type of cell, that is, the PCI of the first cell does not belong to the PCI of the first type of cell, then the terminal 101 can determine that the first cell is not the first type of cell, for example, determine that the first cell is a second type of cell.

[0241] Step S2204: The first cell is a first type cell, and the terminal 101 determines to execute the first behavior.

[0242] In some embodiments, terminal 101 determines that the first cell is a first-category cell based on the first information, and terminal 101 may determine to execute a first behavior. Exemplarily, the first information is the PCI of the first cell. Terminal 101 may determine that the first cell is a first-category cell based on the PCI of the first cell, and terminal 101 may execute the first behavior.

[0243] In some embodiments, the first behavior may include but is not limited to at least one of the following: performing cell selection or cell reselection; adjusting the cell selection or cell reselection priority of the first cell to the lowest priority. That is, when the terminal 101 performs cell selection or cell reselection (or during the cell selection or cell reselection process), if the terminal 101 determines that the first cell is a first-category cell, the terminal 101 cannot reside in the first cell and needs to continue to perform cell selection or cell reselection, or the terminal 101 may adjust the cell selection or cell reselection priority of the first cell to the lowest priority, that is, regard the first cell as the lowest priority, and avoid or suspend treating the first cell as a normal cell selection or reselection by selecting another cell or lowering the priority.

[0244] Step S2205: Based on the first information, it is determined that the first cell is a second-type cell, and the terminal 101 resides in the first cell.

[0245] In some embodiments, the first information is the PCI of the first cell. Terminal 101 may determine, based on the PCI of the first cell, that the first cell is a second-category cell, and then terminal 101 may reside in the first cell. That is, during cell selection or cell reselection (or during cell selection or cell reselection), if terminal 101 determines that the first cell is not a first-category cell (e.g., the first cell is a normal cell or a non-NES cell), and if it is a second-category cell, then terminal 101 may reside in the first cell.

[0246] The method involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2205. For example, step S2201, step S2202, and step S2204 can be implemented as an independent embodiment, step S2201, step S2202, and step S2205 can be implemented as an independent embodiment, step S2201, step S2202, step S2203, and step S2204 can be implemented as an independent embodiment, step S2201, step S2202, step S2203, and step S2205 can be implemented as an independent embodiment, and step S2201, step S2202, step S2203, step S2204, and step S2205 can be implemented as an independent embodiment, but the present invention is not limited thereto.

[0247] In some embodiments, steps S2201 and S2202 may be performed in an interchanged order or simultaneously. For example, terminal 101 may first obtain first information, and based on the first information, determine whether the first cell is a first-category cell, and then terminal 101 performs cell selection or cell reselection. For example, terminal 101 may first perform cell selection or cell reselection, and during the cell selection or cell reselection process, obtain first information, and based on the first information, determine whether the first cell is a first-category cell. This disclosure does not specifically limit this, and specific implementations may be performed according to actual circumstances, and will not be elaborated upon here.

[0252] In some embodiments, step S2204 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0253] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2B .

[0254] 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.

[0255] In step S2301, the terminal 101 performs cell selection or cell reselection.

[0256] In some embodiments, the above-mentioned cell selection or cell reselection includes the first cell.

[0257] The optional implementation of step S2301 can refer to the optional implementation of step S2102 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0258] In step S2302, the terminal 101 obtains first information, which may be the frequency to which the first cell belongs.

[0259] In some embodiments, the first information may be used to indicate whether the first cell is a first-category cell. In some embodiments, the first-category cell is, for example, a cell that supports on-demand request transmission of an SSB and / or a first SIB1.

[0260] In some embodiments, the first information may be carried in system information, where the system information may be a SIB sent by the first network device 102 within the first cell, or the system information may be carried in a SIB sent by the first network device 102 within the first cell. Exemplarily, the SIB may be SIB1, or may be another type of SIB, such as SIB4. Exemplarily, the system information may include the frequency to which the first cell belongs.

[0261] In some embodiments, the first information may be carried in system information, where the system information may be a SIB sent by the second network device 103 within the second cell, or the system information may be carried in a SIB sent by the second network device 103 within the second cell. Exemplarily, the SIB may be SIB1, or may be another type of SIB, such as SIB3, SIB4, etc. Exemplarily, the system information may include the frequency to which the first cell belongs. Exemplarily, the second cell may be a neighboring cell of the first cell, for example, the second cell and the first cell have overlapping coverage or adjacent coverage, that is, the second cell and the first cell are in a neighboring cell relationship.

[0262] It is worth noting that the first information can also be obtained in other ways, which are not specifically limited in this disclosure and will not be described in detail. In other words, the terminal 101 can also obtain the frequency of the first cell in other ways, so that the terminal 101 can determine whether the first cell is a first-category cell based on the frequency of the first cell.

[0263] In step S2303 , the terminal 101 determines whether the first cell is a first-category cell based on the first information.

[0264] In some embodiments, the first information is the frequency to which the first cell belongs. The terminal 101 may determine whether the first cell is a first-category cell based on the frequency to which the first cell belongs.

[0265] In some embodiments, possible implementations of the terminal 101 determining whether the first cell is a first-category cell based on the first information may include: if the first information is included in the frequency of the first-category cell, the first cell is determined to be a first-category cell; or if the first information is not included in the frequency of the first-category cell, the first cell is determined to be a second-category cell. In some embodiments, the frequency of the first-category cell may be a reserved / allocated frequency range or a frequency list, that is, it can be understood as a frequency specifically used for the first-category cell. For example, a frequency range can be reserved / allocated for the first-category cell or a frequency list can be defined for the first-category cell.

[0266] Exemplarily, the first information is the frequency to which the first cell belongs. The terminal 101 determines that the frequency to which the first cell belongs is included in the frequencies of the first type of cells, that is, the frequency to which the first cell belongs is the frequency used by the first type of cells. Then, the terminal 101 can determine that the first cell is a first type of cell. If the terminal 101 determines that the frequency to which the first cell belongs is not included in the frequencies of the first type of cells, that is, the frequency to which the first cell belongs is not the frequency used by the first type of cells, then the terminal 101 can determine that the first cell is not the first type of cell, for example, determine that the first cell is a second type of cell. In some embodiments, the terms "frequency", "frequency point", "frequency band", etc. can be used interchangeably. The terms "frequency list", "frequency point list", "frequency band list", etc. can be used interchangeably.

[0267] Step S2304: The first cell is a first type cell, and the terminal 101 determines to execute the first behavior.

[0268] In some embodiments, terminal 101 determines that the first cell is a first-category cell based on the first information, and terminal 101 may determine to execute a first behavior. Exemplarily, the first information is a frequency to which the first cell belongs, and terminal 101 may determine that the first cell is a first-category cell based on the frequency to which the first cell belongs, and terminal 101 may execute the first behavior.

[0269] In some embodiments, the first behavior may include but is not limited to at least one of the following: performing cell selection or cell reselection; adjusting the cell selection or cell reselection priority of the first cell to the lowest priority. That is, when the terminal 101 performs cell selection or cell reselection (or during the cell selection or cell reselection process), if the terminal 101 determines that the first cell is a first-category cell, the terminal 101 cannot reside in the first cell and needs to continue to perform cell selection or cell reselection, or the terminal 101 may adjust the cell selection or cell reselection priority of the first cell to the lowest priority, that is, regard the first cell as the lowest priority, and avoid or suspend treating the first cell as a normal cell selection or reselection by selecting another cell or lowering the priority.

[0270] Step S2305: Based on the first information, it is determined that the first cell is a second-type cell, and the terminal 101 resides in the first cell.

[0271] In some embodiments, the first information is the frequency to which the first cell belongs. Terminal 101 may determine, based on the frequency to which the first cell belongs, that the first cell is a second-category cell, and then terminal 101 may reside in the first cell. That is, during cell selection or cell reselection (or during the cell selection or cell reselection process), if terminal 101 determines that the first cell is not a first-category cell (e.g., the first cell is a normal cell or a non-NES cell), and if it is a second-category cell, then terminal 101 may reside in the first cell.

[0272] The method involved in the embodiments of the present disclosure may include at least one of steps S2301 to S2305. For example, steps S2301, S2302, and S2304 can be implemented as independent embodiments, steps S2301, S2302, and S2305 can be implemented as independent embodiments, steps S2301, S2302, S2303, and S2304 can be implemented as independent embodiments, steps S2301, S2302, S2303, and S2305 can be implemented as independent embodiments, and steps S2301, S2302, S2303, S2304, and S2305 can be implemented as independent embodiments, but are not limited thereto.

[0273] In some embodiments, steps S2301 and S2302 may be performed in an interchanged order or simultaneously. For example, the terminal 101 may first obtain the first information, and based on the first information, determine whether the first cell is a first-category cell, and then the terminal 101 may perform cell selection or cell reselection. For example, the terminal 101 may first perform cell selection or cell reselection, and during the cell selection or cell reselection process, obtain the first information, and based on the first information, determine whether the first cell is a first-category cell. This disclosure does not specifically limit this, and specific implementations may be performed according to actual circumstances, and will not be elaborated upon here.

[0274] In some embodiments, step S2301 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0275] In some embodiments, step S2303 and step S2305 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0276] In some embodiments, step S2303 and step S2304 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0277] In some embodiments, step S2305 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0278] In some embodiments, step S2304 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0279] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2C .

[0280] 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.

[0281] In step S2401, the first network device 102 sends a SIB in a first cell, where the SIB includes first information, where the first information is used to indicate whether the first cell is a cell of type 1. For example, the SIB may be SIB1.

[0282] In some embodiments, the first type of cell is, for example, a cell that supports on-demand request transmission of an SSB and / or a first SIB1.

[0283] In some embodiments, the SIB may be sent in the first cell by the first network device 102. For example, the first network device 102 sends the SIB in a broadcast manner in the first cell, and accordingly, the terminal may receive the SIB sent by the first network device in the first cell.

[0284] In some embodiments, the SIB sent by the first network device 102 in the first cell includes first information, and the first information in the SIB can be used to indicate whether the first cell is a first-category cell. Exemplarily, a bit in the SIB can be used to indicate that the first cell is a first-category cell. For example, a new IE is defined in the SIB to indicate that the first cell is a first-category cell. For example, the defined new IE can be ondemandSSBrequired (or other names, which are not specifically limited in this disclosure). A 1-bit indicator bit can be used. Exemplarily, if the indication bit in the SIB sent by the first network device 102 in the first cell is present, it indicates that the first cell is a first-category cell. If the indication bit in the SIB sent by the first network device 102 in the first cell is absent, it indicates that the first cell is a second-category cell. Exemplarily, if the indication bit in the SIB sent by the first network device 102 in the first cell is present, it indicates that the first cell is a second-category cell. If the indication bit in the SIB sent by the first network device 102 in the first cell is absent, it indicates that the first cell is a first-category cell. Exemplarily, a 2-bit indicator may be used. For example, if the value of the first information in the SIB sent by the first network device 102 in the first cell is enabled, it indicates that the first cell is a first-category cell. If the value of the first information in the SIB sent by the first network device 102 in the first cell is disabled, it indicates that the first cell is a second-category cell. For another example, if the value of the first information in the SIB sent by the first network device 102 in the first cell is enabled, it indicates that the first cell is a second-category cell. If the value of the first information in the SIB sent by the first network device 102 in the first cell is disabled, it indicates that the first cell is a first-category cell. For another example, if the value of the first information in the SIB sent by the first network device 102 in the first cell is 1, it indicates that the first cell is a first-category cell. If the value of the first information in the SIB sent by the first network device 102 in the first cell is 0, it indicates that the first cell is a second-category cell. For another example, if the value of the first information in the SIB sent by the first network device 102 within the first cell is 0, it indicates that the first cell is a first-category cell. If the value of the first information in the SIB sent by the first network device 102 within the first cell is 1, it indicates that the first cell is a second-category cell. Alternatively, the first information in the SIB may also be in other indication forms, which is not limited in this disclosure and will not be described in detail.

[0285] In some embodiments, the SIB sent by the first network device 102 in the first cell may be SIB1, or may be other types of SIBs, which are not limited in this disclosure and will not be described in detail.

[0286] In step S2402, the terminal 101 performs cell selection or cell reselection.

[0287] In some embodiments, the above-mentioned cell selection or cell reselection includes the first cell.

[0288] The optional implementation of step S2402 can refer to the optional implementation of step S2102 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0289] In step S2403 , the terminal 101 determines whether the first cell is a first-category cell based on the first information.

[0290] In some embodiments, the first information is carried in the SIB, and the terminal 101 can determine whether the first cell is a first-category cell based on the first information in the SIB sent by the first network device 102 in the first cell.

[0291] In some embodiments, possible implementations of the terminal 101 determining whether the first cell is a first-category cell based on the first information in the SIB sent by the first network device 102 within the first cell may include: if the first information exists in the SIB, determining that the first cell is a first-category cell; or if the first information does not exist in the SIB, determining that the first cell is a second-category cell. Exemplarily, a bit in the SIB may be used to indicate that the first cell is a first-category cell. For example, a new IE is defined in the SIB to indicate that the first cell is a first-category cell. For example, the defined new IE may be ondemandSSBrequired (it may also be called other names, which are not specifically limited in this disclosure). A 1-bit indicator may be used. For example, if the indication bit in the SIB sent by the first network device 102 in the first cell exists, that is, the first information exists in the SIB sent by the first network device 102 in the first cell, it indicates that the first cell is a first-category cell. If the indication bit in the SIB sent by the first network device 102 in the first cell is default, that is, the first information does not exist in the SIB sent by the first network device 102 in the first cell, it indicates that the first cell is a second-category cell. The terminal 101 receives the SIB sent by the first network device 102 in the first cell. If the first information exists in the SIB, the terminal 101 can determine that the first cell is a first-category cell. If the first information does not exist (or is default) in the SIB, it indicates that the first cell is a second-category cell.

[0292] In some embodiments, possible implementations of the terminal 101 determining whether the first cell is a first-category cell based on the first information in the SIB sent by the first network device 102 within the first cell may include: if the first information exists in the SIB, determining that the first cell is a second-category cell; or if the first information does not exist in the SIB, determining that the first cell is a first-category cell. Exemplarily, a bit in the SIB may be used to indicate that the first cell is a first-category cell. For example, a new IE is defined in the SIB to indicate that the first cell is a first type cell. For example, the defined new IE may be non-OndemandSSBrequired (it may also be called other names, which are not specifically limited in this disclosure). A 1-bit indicator may be used. For example, if the indication bit in the SIB sent by the first network device 102 in the first cell exists, that is, the first information exists in the SIB sent by the first network device 102 in the first cell, it indicates that the first cell is a second type cell. If the indication bit in the SIB sent by the first network device 102 in the first cell is default, that is, the first information does not exist in the SIB sent by the first network device 102 in the first cell, it indicates that the first cell is a first type cell. The terminal 101 receives the SIB sent by the first network device 102 in the first cell. If the first information exists in the SIB, the terminal 101 can determine that the first cell is a second type cell. If the SIB does not contain (or defaults to) the first information, it indicates that the first cell is a first type cell.

[0293] In some embodiments, a possible implementation method for the terminal 101 to determine whether the first cell is a first type cell based on the first information in the SIB sent by the first network device 102 in the first cell may include: the first information is a first value, determining that the first cell is a first type cell; or the first information is a second value, determining that the first cell is a second type cell. Exemplarily, a 2-bit indicator may be used. For example, if the first information in the SIB sent by the first network device 102 in the first cell has a value of enabled, it indicates that the first cell is a first type cell. If the first information in the SIB sent by the first network device 102 in the first cell has a value of disabled, it indicates that the first cell is a second type cell. For another example, if the first information in the SIB sent by the first network device 102 in the first cell has a value of enabled, it indicates that the first cell is a second type cell. If the first information in the SIB sent by the first network device 102 in the first cell has a value of disabled, it indicates that the first cell is a first type cell. For another example, if the value of the first information in the SIB sent by the first network device 102 in the first cell is 1, it indicates that the first cell is a first-category cell; if the value of the first information in the SIB sent by the first network device 102 in the first cell is 0, it indicates that the first cell is a second-category cell. For another example, if the value of the first information in the SIB sent by the first network device 102 in the first cell is 0, it indicates that the first cell is a first-category cell; if the value of the first information in the SIB sent by the first network device 102 in the first cell is 1, it indicates that the first cell is a second-category cell. Alternatively, the first information in the SIB may also be in other indication forms, which is not limited in this disclosure and will not be described in detail. When the terminal 101 receives the SIB sent by the first network device 102 in the first cell, if the value of the first information in the SIB is the first value, the terminal 101 can determine that the first cell is a first-category cell; if the value of the first information in the SIB is the second value, it indicates that the first cell is a second-category cell.

[0294] Step S2404: The first cell is a first type cell, and the terminal 101 determines to execute the first behavior.

[0295] In some embodiments, terminal 101 determines that the first cell is a first-category cell based on the first information, and terminal 101 may determine to execute a first behavior. Exemplarily, the first information is carried in a SIB, and terminal 101 receives the SIB sent by first network device 102 in the first cell. Terminal 101 may determine that the first cell is a first-category cell based on the first information in the SIB, and terminal 101 may execute the first behavior.

[0296] In some embodiments, the first behavior may include but is not limited to at least one of the following: performing cell selection or cell reselection; adjusting the cell selection or cell reselection priority of the first cell to the lowest priority. That is, when the terminal 101 performs cell selection or cell reselection (or during the cell selection or cell reselection process), if the terminal 101 determines that the first cell is a first-category cell, the terminal 101 cannot reside in the first cell and needs to continue to perform cell selection or cell reselection, or the terminal 101 may adjust the cell selection or cell reselection priority of the first cell to the lowest priority, that is, regard the first cell as the lowest priority, and avoid or suspend treating the first cell as a normal cell selection or reselection by selecting another cell or lowering the priority.

[0297] Step S2405: Based on the first information, it is determined that the first cell is a second-type cell, and the terminal 101 resides in the first cell.

[0298] In some embodiments, the first information is carried in the SIB. When the terminal 101 receives the SIB sent by the first network device 102 in the first cell, it can determine that the first cell is a second-category cell based on the first information in the SIB, and the terminal 101 can camp on the first cell. That is, when the terminal 101 selects or reselects a cell (or during the cell selection or reselection process), if the terminal 101 determines that the first cell is not a first-category cell (such as the first cell is a normal cell or a non-NES cell), if it is a second-category cell, the terminal 101 can camp on the first cell.

[0299] The method involved in the embodiments of the present disclosure may include at least one of steps S2401 to S2405. For example, step S2401, step S2402, and step S2404 can be implemented as an independent embodiment, step S2401, step S2402, and step S2405 can be implemented as an independent embodiment, step S2401, step S2402, step S2403, and step S2404 can be implemented as an independent embodiment, step S2401, step S2402, step S2403, and step S2405 can be implemented as an independent embodiment, and step S2401, step S2402, step S2403, step S2404, and step S2405 can be implemented as an independent embodiment, but the present invention is not limited thereto.

[0300] In some embodiments, step S2401 and step S2402 may be performed in an interchanged order or simultaneously. Exemplarily, the terminal 101 may first receive the SIB sent by the first network device in the first cell, and determine whether the first cell is a first-category cell based on the first information in the SIB, and then the terminal 101 performs cell selection or cell reselection. Exemplarily, the terminal 101 may first perform cell selection or cell reselection, and during the cell selection or cell reselection process, receive the SIB sent by the first network device in the first cell, and determine whether the first cell is a first-category cell based on the first information in the SIB. This disclosure does not make specific limitations on this, and it can be implemented specifically according to actual conditions, which will not be described in detail here.

[0301] In some embodiments, step S2402 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0302] In some embodiments, step S2403 and step S2405 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0303] In some embodiments, step S2403 and step S2404 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0304] In some embodiments, step S2405 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0305] In some embodiments, step S2404 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0306] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2D .

[0307] 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.

[0308] Step S2501: The second network device sends a SIB in a second cell, where the SIB includes a neighbor cell list.

[0309] In some embodiments, the second cell is, for example, a cell where the terminal 101 resides.

[0310] In some embodiments, the neighboring cell list may include at least one cell. Each of the at least one cell is associated with a cell information. The cell information includes a second information, that is, one cell is associated with a second information, and the second information is used to indicate whether the cell associated with the second information is a first-category cell. The first-category cell is, for example, a cell that supports on-demand request transmission of a synchronization signal block (SSB) and / or a first system information block (SIB1).

[0311] In some embodiments, the SIB may be sent by the second network device 103 within the second cell. Exemplarily, the second network device 103 broadcasts the SIB within the second cell, and accordingly, the terminal may receive the SIB sent by the second network device 103 within the second cell. In some embodiments, based on second information associated with at least one cell in a neighbor list in the SIB, it may be indicated whether the cell associated with the second information is a first-category cell.

[0312] Exemplarily, the neighboring cell list in the above-mentioned SIB may include cell information of a cell (such as a neighboring cell of the second cell), and the cell information may include but is not limited to the PCI of the cell, etc. One cell is associated with one second information, and the second information may indicate whether the corresponding cell is a first-class cell.

[0313] In some embodiments, the SIB may be SIB3, and the neighbor list is the IntraFreqNeighCellInfo parameter in SIB3. In some embodiments, the SIB may be SIB4, and the neighbor list is the InterFreqNeighCellInfo parameter in SIB4.

[0314] In some embodiments, the SIB may be SIB3, the neighbor list may be the IntraFreqNeighCellInfo parameter in SIB3, and the second information associated with the at least one cell may be a newly defined IE in the IntraFreqNeighCellInfo in SIB3, indicating whether the cell associated with the second information is a first-category cell. For example, the second information may be indicated by a 2-bit indicator, where a value of 1 indicates that the cell associated with the second information is a first-category cell, and a value of 0 indicates that the cell associated with the second information is a second-category cell; or a value of 0 indicates that the cell associated with the second information is a first-category cell, and a value of 1 indicates that the cell associated with the second information is a second-category cell; or through an (enable, disable) indication, where a value of enable indicates that the cell associated with the second information is a first-category cell, and a value of disable indicates that the cell associated with the second information is a second-category cell; or a value of enable indicates that the cell associated with the second information is a second-category cell, and a value of disable indicates that the cell associated with the second information is a first-category cell. Alternatively, the second information may be indicated by a 1-bit indicator bit, where the indication bit present indicates that the cell associated with the second information is a first-category cell, and by default, indicates that the cell associated with the second information is a second-category cell; or, the bit present indicates that the cell associated with the second information is a second-category cell, and by default, indicates that the cell associated with the second information is a first-category cell. Alternatively, there may be other indication forms, which are not specifically limited in this disclosure.

[0315] In some embodiments, the SIB may be SIB4, the neighbor list may be the InterFreqNeighCellInfo parameter in SIB4, and the second information in the neighbor list may be an IE newly defined in the InterFreqNeighCellInfo in SIB4, indicating whether the cell associated with the second information is a first-category cell. For example, the second information may be indicated by a 2-bit indicator, where a value of 1 indicates that the cell associated with the second information is a first-category cell, and a value of 0 indicates that the cell associated with the second information is a second-category cell; or a value of 0 indicates that the cell associated with the second information is a first-category cell, and a value of 1 indicates that the cell associated with the second information is a second-category cell; or through an (enable, disable) indication, where a value of enable indicates that the cell associated with the second information is a first-category cell, and a value of disable indicates that the cell associated with the second information is a second-category cell; or a value of enable indicates that the cell associated with the second information is a second-category cell, and a value of disable indicates that the cell associated with the second information is a first-category cell. Alternatively, the second information may be indicated by a 1-bit indicator bit, where the indication bit present indicates that the cell associated with the second information is a first-category cell, and by default, indicates that the cell associated with the second information is a second-category cell; or, the bit present indicates that the cell associated with the second information is a second-category cell, and by default, indicates that the cell associated with the second information is a first-category cell. Alternatively, there may be other indication forms, which are not specifically limited in this disclosure.

[0316] In step S2502, the terminal 101 determines whether the cell associated with the second information is a first type cell based on the second information.

[0317] In some embodiments, the terminal 101 receives the SIB sent by the second network device 103 in the second cell, and can determine whether the cell associated with the second information is a first-category cell based on the second information in the neighbor list of the SIB.

[0318] In some embodiments, possible implementation methods for the terminal 101 to determine whether the cell associated with the second information is a first-category cell based on the second information in the above-mentioned neighboring cell list may include: if the second information exists in the above-mentioned neighboring cell list, determining that the cell associated with the second information is a first-category cell; or, if the second information does not exist in the above-mentioned neighboring cell list, determining that the cell associated with the second information is a second-category cell.

[0319] Exemplarily, taking the IntraFreqNeighCellInfo parameter in SIB3 as the neighbor list, a new IE (i.e., the second information in this embodiment) can be defined in the IntraFreqNeighCellInfo in SIB3 to indicate whether the cell associated with the second information is a first-category cell. The second information can be indicated by a 1-bit indication bit, and the indication bit present indicates that the cell associated with the second information is a first-category cell, and the default indicates that the cell associated with the second information is a second-category cell. The terminal 101 receives the SIB3 sent by the second network device in the second cell, and determines that the second information exists in the IntraFreqNeighCellInfo in the SIB3 (or the indication bit exists), then the terminal 101 determines that the cell associated with the second information is a first-category cell; if it determines that the second information does not exist in the IntraFreqNeighCellInfo in the SIB3 (or the indication bit is default, or the second information is default), then the terminal 101 determines that the cell associated with the second information is a second-category cell.

[0320] Exemplarily, taking the InterFreqNeighCellInfo parameter in SIB4 as an example, a new IE (i.e., the second information in this embodiment) can be defined in InterFreqNeighCellInfo in SIB4 to indicate whether the cell associated with the second information is a first-category cell. The second information can be indicated by a 1-bit indication bit, and the indication bit present indicates that the cell associated with the second information is a first-category cell, and the default indicates that the cell associated with the second information is a second-category cell. The terminal 101 receives the SIB4 sent by the second network device in the second cell, and determines that the second information exists in the IntraFreqNeighCellInfo in the SIB4 (or the indication bit exists), then the terminal 101 determines that the cell associated with the second information is a first-category cell; if it determines that the second information does not exist in the IntraFreqNeighCellInfo in the SIB4 (or the indication bit is default, or the second information is default), then the terminal 101 determines that the cell associated with the second information is a second-category cell.

[0321] In some embodiments, possible implementation methods for the terminal 101 to determine whether the cell associated with the second information is a first-category cell based on the second information in the above-mentioned neighboring cell list may include: if the second information exists in the above-mentioned neighboring cell list, determining that the cell associated with the second information is a second-category cell; or, if the second information does not exist in the above-mentioned neighboring cell list, determining that the cell associated with the PCI associated with the second information is a first-category cell.

[0322] Exemplarily, taking the IntraFreqNeighCellInfo parameter in SIB3 as the neighbor list, a new IE (i.e., the second information in this embodiment) can be defined in the IntraFreqNeighCellInfo in SIB3 to indicate whether the cell associated with the second information is a first-category cell. The second information can be indicated by a 1-bit indication bit, and the indication bit present indicates that the cell associated with the second information is a second-category cell, and the default indicates that the cell associated with the second information is a first-category cell. The terminal 101 receives the SIB3 sent by the second network device in the second cell, and determines that the second information exists in the IntraFreqNeighCellInfo in the SIB3 (or the indication bit exists), then the terminal 101 determines that the cell associated with the second information is a second-category cell; if it determines that the second information does not exist in the IntraFreqNeighCellInfo in the SIB3 (or the indication bit is default, or the second information is default), then the terminal 101 determines that the cell associated with the second information is a first-category cell.

[0323] Exemplarily, taking the InterFreqNeighCellInfo parameter in SIB4 as an example, a new IE (i.e., the second information in this embodiment) can be defined in InterFreqNeighCellInfo in SIB4 to indicate whether the cell associated with the second information is a first-category cell. The second information can be indicated by a 1-bit indicator bit, and the indication bit present indicates that the cell associated with the second information is a second-category cell, and the default indicates that the cell associated with the second information is a first-category cell. The terminal 101 receives the SIB4 sent by the second network device in the second cell, and determines that the second information exists in the IntraFreqNeighCellInfo in the SIB4 (or the indication bit exists), then the terminal 101 determines that the cell associated with the second information is a second-category cell; if it determines that the second information does not exist in the IntraFreqNeighCellInfo in the SIB4 (or the indication bit is default, or the second information is default), then the terminal 101 determines that the cell associated with the second information is a first-category cell.

[0324] In some embodiments, possible implementation methods for the terminal 101 to determine whether the cell associated with the second information in the above-mentioned neighboring cell list is a first-category cell may include: the second information is a first value, and the cell associated with the second information is determined to be a first-category cell; or, the second information is a second value, and the cell associated with the second information is determined to be a second-category cell.

[0325] Exemplarily, taking the neighbor list as the IntraFreqNeighCellInfo parameter in SIB3 as an example, a new IE (i.e., the second information in this embodiment) can be defined in the IntraFreqNeighCellInfo in SIB3 to indicate whether the cell associated with the second information is a first-category cell. The second information can be indicated by a 2-bit indicator bit, where a value of 1 indicates that the cell associated with the second information is a first-category cell, and a value of 0 indicates that the cell associated with the second information is a second-category cell; or a value of 0 indicates that the cell associated with the second information is a first-category cell, and a value of 1 indicates that the cell associated with the second information is a second-category cell; or through an (enable, disable) indication, where a value of enable indicates that the cell associated with the second information is a first-category cell, and a value of disable indicates that the cell associated with the second information is a second-category cell, or a value of enable indicates that the cell associated with the second information is a second-category cell, and a value of disable indicates that the cell associated with the second information is a first-category cell. The terminal 101 receives the SIB3 sent by the second network device in the second cell, and determines that the value of the second information in the IntraFreqNeighCellInfo in the SIB3 is the first value, then the terminal 101 determines that the cell associated with the second information is a first type cell; determines that the value of the second information in the IntraFreqNeighCellInfo in the SIB3 is the second value, then the terminal 101 determines that the cell associated with the second information is a second type cell.

[0326] Exemplarily, taking the InterFreqNeighCellInfo parameter in SIB4 as the neighbor list, a new IE (i.e., the second information in this embodiment) can be defined in InterFreqNeighCellInfo in SIB4 to indicate whether the cell associated with the second information is a first-category cell. The second information can be indicated by a 2-bit indicator, where a value of 1 indicates that the cell associated with the second information is a first-category cell, and a value of 0 indicates that the cell associated with the second information is a second-category cell; or a value of 0 indicates that the cell associated with the second information is a first-category cell, and a value of 1 indicates that the cell associated with the second information is a second-category cell; or through an (enable, disable) indication, where a value of enable indicates that the cell associated with the second information is a first-category cell, and a value of disable indicates that the cell associated with the second information is a second-category cell, or a value of enable indicates that the cell associated with the second information is a second-category cell, and a value of disable indicates that the cell associated with the second information is a first-category cell. The terminal 101 receives the SIB4 sent by the second network device in the second cell, and determines that the value of the second information in the IntraFreqNeighCellInfo in the SIB4 is the first value, then the terminal 101 determines that the cell associated with the second information is a first type cell; determines that the value of the second information in the IntraFreqNeighCellInfo in the SIB4 is the second value, then the terminal 101 determines that the cell associated with the second information is a second type cell.

[0327] Step S2503: The cell associated with the second information is a first-category cell, and the terminal 101 determines to execute the second behavior.

[0328] In some embodiments, terminal 101 determines, based on the second information in the aforementioned neighboring cell list, that the cell associated with the second information is a first-category cell, and terminal 101 may determine to execute a second behavior. Exemplarily, terminal 101 receives an SIB sent by second network device 103 within the second cell, and may determine, based on the second information in the neighboring cell list of the SIB, that the cell associated with the second information is a first-category cell, and terminal 101 may execute the second behavior.

[0329] In some embodiments, the second behavior may include but is not limited to at least one of the following: adjusting the cell selection or cell reselection priority of the cell associated with the second information to the lowest priority; excluding the cell associated with the second information as a candidate cell for cell selection or cell reselection. That is, when the terminal 101 is selecting or reselecting a cell (or during the cell selection or cell reselection process), if the terminal 101 determines that the cell associated with the second information is a first-category cell, the terminal 101 may adjust the cell selection or cell reselection priority of the cell associated with the second information to the lowest priority, and / or, the terminal 101 may exclude the cell associated with the second information as a candidate cell for cell selection or cell reselection, so that the candidate cells for cell selection or cell reselection do not include the cell associated with the second information, and avoid or postpone the case where the cell associated with the second information is a first-category cell by lowering the priority or excluding it as a candidate cell for cell selection or cell reselection, so that the cell is treated as a normal cell selection or reselection.

[0330] Optionally, in some embodiments, the method may further include step S2504, namely: based on the second information, determining that the cell associated with the second information is a second type cell, and the terminal 101 can cell select or cell reselect to the cell associated with the second information. For example, the terminal 101 can use the cell associated with the second information (i.e., the second type cell) as a candidate cell for cell selection or cell reselection, so that the terminal can cell select or cell reselect to the cell associated with the second information, so that the terminal can reside in the cell associated with the second information.

[0331] In some embodiments, the terminal 101 receives the SIB sent by the second network device 103 in the second cell, and can determine that the cell associated with the second information is a second type cell based on the second information in the neighbor cell list of the SIB, and the terminal 101 can cell select or cell reselect to the cell associated with the second information (i.e., the second type cell), that is, the terminal 101 can reside in the second type cell. In other words, when the terminal 101 selects or reselects the cell (or during the cell selection or cell reselection process), if the terminal 101 determines that the cell associated with the second information is not a first type cell (such as the first cell is a normal cell or a non-NES cell), if it is a second type cell, the terminal 101 can reside in the cell associated with the second information.

[0332] The method involved in the embodiments of the present disclosure may include at least one of steps S2501 to S2504. For example, step S2501 + step S2503 can be implemented as an independent embodiment, step S2501 + step S2504 can be implemented as an independent embodiment, step S2501 + step S2502 + step S2503 can be implemented as an independent embodiment, step S2501 + step S2502 + step S2504 can be implemented as an independent embodiment, step S2501 + step S2503 + step S2504 can be implemented as an independent embodiment, and step S2501 + step S2502 + step S2503 + step S2504 can be implemented as an independent embodiment, but the present invention is not limited thereto.

[0340] Step S3101: Receive the MIB sent by the first network device 102 in the first cell.

[0341] 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.

[0342] In some embodiments, the first information in the above-mentioned MIB can be used to indicate whether the first cell is a first-type cell, where the first-type cell is, for example, a cell that supports on-demand request transmission of SSB and / or the first SIB1.

[0519] In some embodiments, the above method may include the method described in the above embodiments of the terminal side, the second network device side, etc., which will not be repeated here.

[0520] It should be noted that the present disclosure proposes a communication method involving a cell selection and reselection solution, which can solve the problem of how to enable a terminal supporting the R19 on demand request SSB feature (i.e., the above-mentioned R19 version UE supports requesting SSB and / or SIB1) to identify that a cell is an NES cell (i.e., the first type of cell in this article) in a carrier aggregation scenario, and avoid or temporarily suspend treating such an NES cell as a normal cell selection or reselection.

[0521] Solution 1: Define indication information to indicate that this cell is an SSB request-based cell.

[0522] In some embodiments, the UE may obtain whether the current cell is an on-demand SSB required cell / NES cell (i.e., the first type of cell in this document) in the following manner:

[0523] Method 1: A bit in the MIB is used to indicate whether the cell is an on-demand SSB required cell / NES cell, such as a spare bit. Exemplarily, it is indicated by a 2-bit indicator bit, a value of 1 indicates that the SSB is based on the requested cell / NES cell, and a value of 0 indicates a normal cell / non-NES cell; or a value of 0 indicates that the SSB is based on the requested cell / NES cell, and a value of 1 indicates a normal cell / non-NES cell, or it is indicated by (enable, disable). Alternatively, it is indicated by a 1-bit indicator bit, the indication bit present indicates that the SSB is based on the requested cell / NES cell, and the default indicates that it is a non-NES cell, or the bit present indicates that it is a non-NES cell, and the default indicates that the SSB is based on the requested cell / NES cell. Or there are other indication forms, which are not specifically limited in the present disclosure.

[0524] Method 2: The UE obtains stored information from other cells or the current cell, indicating that the cell is an on-demand SSB required cell.

[0525] Mode 3: PCI: The system reserves the PCI range or PCI list of cells that support on-demand SSB required.

[0526] Mode 4: Frequency list: The system reserves a frequency list for cells that support on-demand SSB required.

[0527] Method 5: A bit in SIB1 is used to indicate that the cell is an on-demand SSB required cell. For example, a new IE is defined to indicate that the cell is an SSB-requested cell. For example, a new IE, ondemandSSBrequired, is defined. A 1-bit indicator bit is used. Specifically, the indicator bit present indicates that the cell is an SSB-requested cell / NES cell. The default value of this bit indicates that it is a normal cell / non-NES cell. Alternatively, a 2-bit indicator bit is used for indication. The value of this indicator bit is enabled, indicating that the cell is an SSB-requested cell / NES cell. The value of this indicator bit is disabled, indicating that it is a normal cell / non-NES cell. Alternatively, the value of this indicator bit is 1, indicating that the cell is an SSB-requested cell / NES cell. The value of this indicator bit is 0, indicating that it is a normal cell / non-NES cell. Alternatively, there are other indication forms, which are not specifically limited in the present disclosure.

[0528] In some embodiments, when the terminal 101 selects or reselects a cell, if it knows that the cell is an NES cell, the terminal 101 does not reside in the NES cell and continues to perform cell selection or cell reselection, or the terminal 101 regards the cell as the lowest priority.

[0529] Solution 2: The neighbor list indicates that the SSB is based on the requested cell (also called on-demand SSB required cell / NES cell) identifier / frequency band.

[0530] In some embodiments, a new IE is defined in IntraFreqNeighCellInfo in SIB3 to indicate whether a cell associated with a certain PCI is an NES cell / SSB based on a request cell. For example, it is indicated by a 2-bit indicator bit, a value of 1 indicates that the SSB is based on a request cell / NES cell, and a value of 0 indicates a normal cell / non-NES cell; or a value of 0 indicates that the SSB is based on a request cell / NES cell, and a value of 1 indicates a normal cell / non-NES cell, or through (enable, disable) indication. Alternatively, it may be indicated by a 1-bit indicator bit, the indication bit present indicates that the SSB is based on a request cell / NES cell, and the default indicates that it is a non-NES cell, or the bit present indicates that it is a non-NES cell, and the default indicates that the SSB is based on a request cell / NES cell. Or there may be other indication forms, which are not specifically limited in this disclosure.

[0531] In some embodiments, a new IE is defined in InterFreqNeighCellInfo in SIB4 to indicate whether a cell associated with a certain PCI is an NES cell / SSB based on a request cell. For example, it is indicated by a 2-bit indicator bit, a value of 1 indicates that the SSB is based on a request cell / NES cell, and a value of 0 indicates a normal cell / non-NES cell; or a value of 0 indicates that the SSB is based on a request cell / NES cell, and a value of 1 indicates a normal cell / non-NES cell, or it is indicated by (enable, disable). Alternatively, it may be indicated by a 1-bit indicator bit, and the indication bit present indicates that the SSB is based on a request cell / NES cell, and the default indicates that it is a non-NES cell, or the bit present indicates that it is a non-NES cell, and the default indicates that the SSB is based on a request cell / NES cell. Or there may be other indication forms, which are not specifically limited in this disclosure.
