[0024] The technical solution in this application will be described below with reference to the accompanying drawings.

[0025] Wireless communication systems

[0026] Figure 1 is a diagram illustrating an example of the system architecture of a wireless communication system 100 to which an embodiment of the present application may be applied. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 may provide network coverage for a specific geographical area and may communicate with the terminal device 120 located within the coverage area. The terminal device 120 may access a network (e.g., a wireless network) through the network device 110. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0027] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: 5G system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

[0028] The terminal device in the embodiments of the present application may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The terminal device in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user and can be used to connect people, objects, and machines, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, 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. Optionally, the terminal device can be used to act as a base station. For example, the terminal device can act as a scheduling entity that provides sidelink signals between terminal devices in vehicle to everything (V2X) or device to device (D2D). For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through a base station.

The network device may be, for example, an access network device or a wireless access network device. For example, the network device may be a base station. The base station may broadly cover the following various names, or be replaced with the following names: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmitting point (TP), home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station may be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof.

[0030] Application scenarios of communication systems

[0031] Currently, the main application scenarios of communication systems (e.g., 5G) can include enhanced mobile broadband (eMBB), ultra reliable low latency communication (URLLC), and massive machine type communication (mMTC).

[0032] Demand for eMBB, which can be applied to scenarios such as users accessing multimedia content, services, and data, is growing rapidly. Furthermore, eMBB can be deployed in diverse environments, such as indoors, in urban areas, and in rural areas. The capabilities and requirements for eMBB vary significantly in these environments.

[0033] URLLC can be applied to scenarios such as industrial automation, power automation, remote medical operations (surgery), and traffic safety. Typical features of mMTC include high connection density, small data volumes, latency-insensitive services, low module cost, and long service life.

[0034] Radio resource control (RRC) state and mobility management

[0035] Currently, the protocol defines three RRC states of terminal devices: RRC connected (RRC_connected) state, RRC idle (RRC-idle) state and RRC inactive (RRC-inactive) state.

[0036] The RRC connection state may refer to the state in which the terminal device is in when the RRC release is not performed after the random access process is completed. An RRC connection exists between the terminal device and a network device (e.g., an access network device). In the RRC connection state, the terminal device can transmit data with the network device, such as downlink data transmission and / or uplink data transmission. Alternatively, the terminal device can also transmit terminal device-specific data channels and / or control channels with the network device to transmit specific information or unicast information of the terminal device.

[0037] In the RRC connected state, the network device can determine the cell-level location information of the terminal device, that is, the network device can determine the cell to which the terminal device belongs. In the RRC connected state, after the terminal device moves, such as from one cell to another, the network device can control the terminal device to perform cell handover. Therefore, it can be seen that the mobility management of the terminal device in the RRC connected state may include cell handover. In addition, the mobility management of the terminal device in the RRC connected state can be controlled by the network device. Accordingly, the terminal device can switch to a designated cell according to the instructions issued by the network device.

[0038] The RRC idle state refers to the state of the terminal device when it is resident in a cell but is not performing random access. The terminal device usually enters the RRC idle state after being powered on or after RRC is released. In the RRC idle state, there is no RRC connection between the terminal device and the network device (such as the resident network device), the network device does not store the context of the terminal device, and no connection is established between the network device and the core network for the terminal device. If the terminal device needs to enter the RRC connected state from the RRC idle state, it is necessary to initiate the RRC connection establishment process.

[0039] In the RRC idle state, the core network (CN) can send a paging message to the terminal device, that is, the paging process can be triggered by the CN. Optionally, the paging area can also be configured by the CN. In some cases, for a terminal device in the RRC idle state, when the terminal device moves (for example, from one cell to another), the terminal device can initiate a cell reselection process. In other cases, for a terminal device in the RRC idle state, when the terminal device needs to access a cell, the terminal device can initiate a cell selection process. That is, the mobility management of the terminal device in the RRC idle state may include cell reselection and / or cell selection.

[0040] The RRC inactive state is defined to reduce air interface signaling, quickly restore wireless connections, and quickly resume data services. The RRC inactive state is a state between the connected and idle states. A terminal device previously entered the RRC connected state and then released the RRC connection with the network device, but the network device retained the terminal device's context. Furthermore, the connection established between the network device and the core network for the terminal device is not released. This means that the user plane and control plane bearers between the RAN and CN are still maintained, indicating a CN-NR connection.

[0041] In the RRC inactive state, the RAN can send a paging message to the terminal device, that is, the paging process can be triggered by the RAN. The RAN-based paging area is managed by the RAN, and the network equipment can know the location of the terminal device based on the RAN paging area level.

[0042] In some cases, for a terminal device in an RRC inactive state, when the terminal device moves (for example, from one cell to another), the terminal device may initiate a cell reselection process. In other cases, for a terminal device in an RRC inactive state, when the terminal device needs to access a cell, the terminal device may initiate a cell selection process. In other words, the mobility management of a terminal device in an RRC inactive state may include cell reselection and / or cell selection.

[0043] NES Project for 5G

[0044] Energy consumption has become a significant component of operators' operating costs. According to a report by the Global System for Mobile Communications Association (GSMA), mobile network energy costs account for approximately 23% of operators' total costs. Most of this energy consumption comes from radio access networks, particularly active antenna units (AAUs), while data centers and fiber optic transmission contribute only a smaller share.

[0045] There are two types of energy consumption:

[0046] Dynamic part: such as energy consumption during data transmission / reception;

[0047] Static part: such as the energy consumption required to maintain the operation of the wireless access device (even if there is no continuous data transmission / reception).

[0048] The project should not only assess potential network energy consumption but also evaluate and balance the impact on network and user performance. For example, the project should not have a significant impact on key performance indicators (KPIs). These KPIs include spectrum efficiency, capacity, user perceived throughput (UPT), latency, terminal device power consumption, complexity, handover performance, call drop rate, and initial access performance.

[0049] Possible research directions for this project include defining procedures and signaling methods to support on-demand SSB secondary cell (SCell) operation for connected devices configured with carrier aggregation (CA), including intra- and inter-frequency CA. For example, defining triggering methods for SSB transmission (selected from uplink wake-up signals (WUS), cell on / off indication via backhaul, and secondary cell activation / deactivation signaling).

[0050] In addition, possible research directions for this project include studying the process and signaling methods to support on-demand transmission of system information block 1 (SIB1) for terminal devices in idle / inactive state. Specifically, this may include one or more of the following: triggering methods for uplink wake-up signals; configuration information for wake-up signals provided to terminal devices; and information exchange between network devices (at least exchanging wake-up signal configuration information).

[0051] Possible research directions for this project include defining universal signal / channel transmission adaptation techniques. For example, time-domain adaptation of the physical random access channel (PRACH). Another example is studying PRACH adaptation in the spatial domain. Another example is paging opportunity adaptation.

[0052] NES Community

[0053] An NES cell may refer to a cell using NES technology. NES cells may include, for example, SSB-less cells and / or SIB1-less cells. These two types of cells are described below.

[0054] In the related art, the secondary cell may not send SSB, but the premise is that this cell is co-located with the special cell (sPcell) or other secondary cells of the same frequency. If the terminal device has been synchronized with another cell, and the cell is co-located with the SSB-less cell, the terminal device can communicate on the SSB-less cell. Assuming that cell A and cell B (secondary cell) are co-located, and cell B is an SSB-less cell, the terminal device can obtain SSB from cell A for communication on cell B, and cell B never needs to send SSB. In release 18 (R18), the network energy saving project extends the above solution from the same-frequency scenario to the different-frequency scenario, that is, the SSB-less cell can obtain SSB through other cells in different frequency bands.

[0055] In R19, SSB-less cells can still be used as working cells for connected terminal devices. In addition, SIB1-less cells were introduced in R19. These NES cells can be used as working cells for idle / inactive terminal devices.

[0056] As mentioned above, the concept of NES cells has been introduced to achieve network energy conservation. However, there is currently no clear solution for how terminal devices operate in NES cells (for example, how to access NES cells or how to obtain NES cell information).

[0057] In response to the above problems, the embodiments of the present application are described in detail below.

[0058] FIG2 is a flow chart of a wireless communication method according to an embodiment of the present application. The method of FIG2 can be executed by a terminal device and a network device. The terminal device and the network device can be, for example, the terminal device 120 and the network device 110 mentioned above.

[0059] Referring to Figure 2, in step S210, the terminal device receives NES cell information (or NES frequency information) sent by the network device. The NES cell can be a cell that uses or supports NES technology. For example, the NES cell can include an SSB-less cell and / or a SIB1-less cell. In the embodiment of the present application, the network device provides the terminal device with NES cell information, which helps the terminal device operate in the NES cell.

[0060] In some implementations, the NES cell information is obtained through one or more of the following cells: a first cell, a cell where the terminal device previously resided, an anchor cell of the NES cell, a cell accessed between terminal devices, a cell where the terminal device last resided, and a cell that last served the terminal device. It should be understood that the first cell may be one of the following cells: a cell where the terminal device previously resided, an anchor cell of the NES cell, a cell accessed between terminal devices, a cell where the terminal device last resided, and a cell that last served the terminal device. Alternatively, the first cell may be a cell other than the cells listed above.

[0061] In some implementations, the NES cell information is information for terminal devices in an idle state or an inactive state. That is, the NES cell information can be used by terminal devices in an idle state or an inactive state.

[0062] The following is a detailed introduction to the information content of the NES community.

[0063] In some implementations, the NES cell information includes information 1. Information 1 is used to indicate one or more of the following: an association relationship between the first cell and the NES cell, and the NES cells associated with the first cell (i.e., indicating which NES cells are associated with the first cell). The NES cells associated with the first cell can be referred to as a list of NES cells.

[0064] In some implementations, the NES cell information includes information 2. Information 2 is used to indicate one or more of the following: the frequency of the NES cell, the SSB frequency of the NES cell, the cell identifier of the NES cell, the physical cell identifier (PCI) of the NES cell, and quasi-colocation (QCL) relationship information of the NES cell. The above information can be used to determine which cell is an NES cell. In the NES cell information, information 2 and information 1 can exist together. Alternatively, only one of information 2 and information 1 can exist.

[0065] In some implementations, the NES cell information includes configuration information of the first message. The first message may be used by the terminal device to send a request message. Alternatively, the first message may be used to request the NES cell to send some or all of the cell common information (such as SIB1). The first message may be any type of message. For example, the first message may be an uplink message or an uplink request message. In another example, the first message may be an uplink wake-up signal (UL WUS). The configuration information of the first message may be used by the terminal device to send the first message.

[0066] The embodiments of the present application do not specifically limit the content of the configuration information of the first message. For example, the configuration information of the first message may include one or more of the following: configuration information of the time domain resources of the first message (i.e., time domain configuration), configuration information of the frequency domain resources of the first message (i.e., frequency domain configuration), a preamble corresponding to the first message, and beam direction information corresponding to the first message.

[0067] It should be understood that the configuration information of the first message may be common configuration information. Alternatively, the configuration information of the first message may be configuration information for the first cell (i.e., all NES cells associated with the first cell may use this configuration information). Alternatively, the configuration information of the first message may be information configured for each NES cell (i.e., per NES cell configuration information). Alternatively, the configuration information of the first message may be information configured for the frequency point of each NES cell (i.e., per NES frequency point configuration information). The configuration information of the first message may be predefined configuration information, or may be information specified by a protocol (communication standard protocol).

[0068] In some implementations, the NES cell information includes a first condition or a first factor. The first condition or the first factor is used to trigger the terminal device to determine whether to send the first message. Alternatively, the first condition or the first factor is used to determine whether a condition for sending the first message is met. Alternatively, the first condition or the first factor is used to trigger the sending of the first message.

[0069] The first condition or the first factor can be set according to actual conditions. For example, the first condition or the first factor is associated with one or more of the following: a cell selection or reselection parameter, information related to data to be transmitted by the terminal device, a bar access parameter, supported slice information, a first information sent by the network device (used to indicate whether the terminal device is allowed to send the first message), whether the terminal device receives the SSB of the NES cell, whether the terminal device receives the SIB1 of the NES cell, the signal quality of the SSB received by the terminal device, the signal quality of the first cell, the difference between the signal quality of the first cell and the signal quality of the NES cell, the frequency priority corresponding to the first cell, and the frequency priority corresponding to the NES cell.

[0070] The cell selection or reselection parameters mentioned above may include one or more of the following: intraFreqReselection parameters, parameters required by the S criterion, parameters required by the R criterion, slices supported by the cell or frequency, frequency priority, a set (list) of cells allowed for use, and a set (list) of cells not allowed for use.

[0071] The information related to the data to be transmitted of the terminal device may be used to indicate the data status of the terminal device, for example, whether the data of the terminal device has arrived, or whether the amount of data to be transmitted of the terminal device is greater than or equal to a first threshold.

[0072] The first condition or first factor mentioned above may be common, may be configured for an NES cell (ie, per NES cell), or may be configured for an NES frequency point (ie, per NES frequency point).

[0073] The first condition or first factor mentioned above may, for example, include one or more of the following: the NES cell meets the cell selection or reselection criteria, uplink data arrives at the terminal device, the amount of uplink data to be transmitted by the terminal device is greater than or equal to the first threshold, the NES cell is not prohibited or blocked from access, the NES cell supports the slices required by the terminal device, the terminal device receives the SSB of the NES cell but does not receive SIB1, the terminal device detects the NES cell but does not receive SIB1, the signal quality of the SSB is greater than or equal to the second threshold, the signal quality of the NES cell is greater than or equal to the third threshold, the signal quality of the current cell of the terminal device is less than or equal to the fourth threshold, the frequency priority corresponding to the current cell of the terminal device is less than the frequency priority corresponding to the NES cell, the current cell of the terminal device does not support the slices required by the terminal device, the signal quality of the first cell is less than or equal to the fifth threshold, the frequency priority corresponding to the first cell is less than the frequency priority corresponding to the NES cell, the first cell does not support the slices required by the terminal device, and the first information indicates that the network device allows the terminal device to send the first message.

[0074] Some more specific examples of the first condition or first factor are given below.

[0075] For example, when the NES cell meets the cell selection or reselection criteria, the terminal device considers that the first condition is met, and / or the terminal device sends a first message.

[0076] For another example, when uplink data arrives at the terminal device, or the amount of uplink data is greater than or equal to a first threshold, the terminal device considers that the first condition is met, and / or sends a first message.

[0077] For another example, if the terminal device obtains the SSB of the NES cell but fails to obtain SIB1, the terminal device considers that the first condition is met and / or sends a first message.

[0078] For example, the terminal device obtains the SSB of the NES cell, and the channel quality based on the SSB (i.e., the channel quality measured based on the SSB) is greater than or equal to the second threshold (such as reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), received signal strength indication (RSSI), etc. is greater than or equal to the second threshold), but the terminal device does not obtain SIB1, then the terminal device considers that the first condition is met, and / or sends a first message.

[0079] For another example, the channel quality of the cell where the terminal device is currently located is less than or equal to the third threshold, the terminal device obtains the SSB of the NES cell, and the channel quality based on the SSB is greater than or equal to the second threshold (such as RSRP, RSRQ, RSSI, etc. are greater than or equal to the second threshold), but the terminal device does not obtain SIB1, then the terminal device considers that the first condition is met, and / or sends a first message.

[0080] For example, the frequency priority corresponding to the cell where the terminal device is currently stationed is less than the frequency priority of the NES cell. The terminal device obtains the SSB of the NES cell and the channel quality based on the SSB is greater than or equal to the second threshold (such as RSRP, RSRQ, RSSI, etc. are greater than or equal to the second threshold), but the terminal device does not obtain SIB1. The terminal device then considers that the first condition is met and / or sends a first message.

[0081] For example, if the network device allows the terminal device to send a first message, the terminal device obtains the SSB of the NES cell, and the channel quality based on the SSB is greater than or equal to the second threshold (such as RSRP, RSRQ, RSSI, etc. is greater than or equal to the second threshold), but the terminal device does not obtain SIB1, then the terminal device considers that the first condition is met, and / or sends the first message.

[0082] For another example, the frequency priority corresponding to the cell where the terminal device resides is less than the frequency priority corresponding to the NES cell, the terminal device obtains the SSB of the NES cell and the channel quality based on the SSB is greater than or equal to the second threshold (such as RSRP, RSRQ, RSSI, etc. are greater than or equal to the second threshold), but the terminal device does not obtain SIB1, then the terminal device considers that the first condition is met, and / or sends a first message.

[0083] For example, if the network device allows the terminal device to send a first message, the terminal device obtains the SSB of the NES cell, and the channel quality based on the SSB is greater than or equal to the second threshold (such as RSRP, RSRQ, RSSI, etc. is greater than or equal to the second threshold), but the terminal device does not obtain SIB1, then the terminal device considers that the first condition is met, and / or sends the first message.

[0084] For another example, if a network device (such as a base station) instructs a terminal device to access another cell (NES cell), or to send a RACH, or to send a first message, the terminal device deems that the first condition is met, and / or sends the first message (further, this condition may be used in combination with other conditions). Furthermore, in some implementations, the network device may instruct the terminal device to access the cell currently residing or another cell, or to send a RACH, through a paging message. For another example, the network may instruct the terminal device to send the first message in another cell through a paging message.

[0085] In some implementations, the NES cell information includes NES cell status information. The NES cell status information may be used to indicate one or more of the following: whether the NES cell is in an energy-saving state, whether the NES cell sends SIB1, and whether the NES cell is available. Thus, based on the NES cell status information, a terminal device may be informed of whether the NES cell sends a SIB1 message; or whether the terminal device needs to send an on-demand message to request SIB1. Alternatively, the terminal device may also be informed of the NES cell status based on whether it can read SIB1 from the NES cell.

[0086] In some implementations, the NES cell information includes part or all of the information (or information element (IE)) in the SIB1 of the NES cell. Part or all of the information in the SIB1 of the NES cell can be used to perform one or more operations such as cell selection, reselection, and RACH.

[0087] In some implementations, the information of the NES cell includes part or all of the information in other SIBs of the NES cell except SIB1.

[0088] The above article has introduced the content of NES cell information in detail. The following article will introduce the method for obtaining (or carrying) NES cell information in detail.

[0089] The information of the NES cell can be obtained through the indication information of the network device (such as a base station). For example, the information of the NES cell is indicated by a first SIB message. The first SIB message can be one of the following: a new SIB message (such as a SIBX message), an existing SIB message, or a SIB message obtained by extending an existing SIB message. Optionally, taking the first SIB message as a SIBX message as an example, the terminal device obtains the information of the NES cell through a SIBX message sent by a cell previously resided, an anchor cell of the NES cell, or a cell previously accessed.

[0090] For another example, the NES cell information is indicated via an RRC message. The RRC message may be, for example, a dedicated RRC message, such as an RRC release message. For example, the terminal device may obtain the NES cell information from an RRC release message sent by a previously accessed cell.

[0091] In some implementations, after obtaining NES cell information, the terminal device may determine NES cell or NES frequency information based on the NES cell information. Alternatively, the terminal device may determine whether an NES cell exists based on the NES cell information. Alternatively, the terminal device may determine whether to request further information about the NES cell (e.g., sending an on-demand message requesting the NES cell to transmit SIB1) based on the NES cell information.

[0092] The method for obtaining NES cell information given above enables the terminal device to obtain NES cell information, determine whether a NES cell exists and / or whether to request further information of the NES cell (such as sending an on-demand message requesting the NES cell to send SIB1), thereby helping the terminal device to work in the NES cell.

[0093] In some implementations, the aforementioned terminal device may reside in the first cell; or, the terminal device may reside in the NES cell.

[0094] In some implementations, the terminal device mentioned above can be referred to as a first terminal device. Furthermore, in some implementations, the first terminal device resides in the NES cell under the following circumstances: sending a first message (see the description of the first message above), or obtaining part or all of the public information of the NES cell, or the NES cell is not in an energy-saving state. The first terminal device mentioned here may, for example, include one or more of the following: a terminal device that supports NES, a terminal device defined in version 19 of the 3rd Generation Partnership Project (3GPP), a terminal device that supports SSB-less, a terminal device that supports SIB1-less, and a terminal device that supports adaptive NES technology (such as adaptive SSB / RACH / paging technology).

[0095] In some implementations, the second terminal device cannot reside in an NES cell. The second terminal device mentioned here can be, for example, a terminal device different from the first terminal device, a terminal device that does not support NES, a terminal device that does not support specific NES technology, a legacy terminal device, or a non-NES terminal device.

[0096] Referring back to Figure 2, in step S210, the terminal device also receives instruction information sent by the network device. This instruction information can be used to control the terminal device's access to the NES cell. Alternatively, this instruction information can be used to control access to the NES cell. In some implementations, the term "access" mentioned here can be replaced with "residence," "selection," "reselection," etc.

[0097] In some implementations, the indication information sent by the network device includes one or more of the following: first indication information and a bar access (bar) parameter.

[0098] The aforementioned barring parameter may be an existing bar parameter. For example, the barring parameter may be cellbarred in the master information block (MIB) or a bar indication (cellReservedForOperatorUse, cellReservedForOtherUse, or cellReservedForFutureUse) in SIB1. Access of legacy terminal devices may be controlled based on the existing barring parameter.

[0099] The first indication information can be used to control the terminal device's access to the NES cell, or to control access to the NES cell. The first indication information can be a new access control parameter introduced in an embodiment of the present application. The first indication information can indicate whether the terminal device is allowed to access the NES cell. Alternatively, the first indication information can indicate the cell type (such as whether it is an NES cell). The embodiment of the present application does not specifically limit the carrying location of the first indication information. For example, the first indication information is carried in the MIB or SIB. For example, the first indication information is carried in SIB1.

[0100] After receiving the indication information from the network device, the terminal device can determine whether it can access the network based on the indication information. The network mentioned here may refer to an NES cell or an NES base station. The NES cell or NES base station may include one or more of the following: an SSB-less cell or base station, a SIB1-less cell or base station, a cell or base station using NES technology (such as a cell or base station using or supporting adaptive SSB / RACH / paging technology, where the adaptation mentioned here may refer to spatial domain adaptation or time domain adaptation).

[0101] The following is a detailed explanation of how the terminal device determines whether it can access the NES cell (or select the NES cell, or reselect the NES cell) based on the access prohibition parameter and / or the first indication information.

[0102] In some implementations, a terminal device is prohibited from accessing an NES cell under a first condition. The first condition includes one or more of the following: failure to receive a SIB1 sent by the NES cell, a prohibited access parameter indicating prohibited access to the cell, failure to receive some or all public information of the NES cell, or the NES cell being in an energy-saving state. The terminal device mentioned here may be any of the types of second terminal devices mentioned above.

[0103] As a specific example, if the terminal device is an old terminal device, then in principle, the old terminal device is not allowed to access the NES cell. The old terminal device can perform access control based on the existing access prohibition parameters. In specific implementation, there are two options. Option 1: If the terminal device cannot obtain SIB1, the terminal device cannot reside in the NES cell, or select the NES cell, or reselect the NES cell. Option 2, the access, selection or reselection of the NES cell of the old terminal device can be controlled based on the existing access prohibition parameters, such as based on cellbarred in the MIB, and / or the bar indication in SIB1 (cellReservedForOperatorUse, or cellReservedForOtherUse, or cellReservedForFutureUse) to control the access, selection or reselection of the NES cell of the old terminal device.

[0104] In some implementations, whether a terminal device is allowed to access an NES cell is determined based on one or more of the following: whether the second message (a message carrying the first indication information) carries the first indication information (whether the second message carries the first indication information can also be understood or replaced by whether the first indication information exists or appears), the indication content of the first indication information, and the indication content of the access prohibition parameter. The terminal device mentioned here can be, for example, the first terminal device mentioned above. In principle, the first terminal device can be allowed to access, select, or reselect the NES cell. However, whether the first terminal device can access, select, or reselect the NES cell can be determined based on the first indication information and / or the access prohibition parameter.

[0105] In some implementations, whether to allow the terminal device to access, select, or reselect an NES cell can be determined based on whether the second message carries the first indication information (or whether the first indication information exists or appears). The first indication information can indicate the cell type (such as whether it is an NES cell). For example, if the second message carries the first indication information (or the first indication information exists or appears), the terminal device is allowed to access the NES cell. For another example, if the second message does not carry the first indication information (or the first indication information does not exist or does not appear), the terminal device is allowed to access the NES cell. Further, optionally, the terminal device can ignore the access prohibition parameter.

[0106] In some implementations, whether to allow a terminal device to access, select, or reselect an NES cell may be determined based on the content of the first indication information. For example, if the first indication information indicates that access to the cell is allowed (not barred), the terminal device is allowed to access the NES cell. For another example, if the first indication information indicates that access to the cell is not allowed (barred), the terminal device is not allowed to access the NES cell. Furthermore, the terminal device may optionally ignore the access prohibition parameter.

[0107] In some implementations, whether to allow the terminal device to access, select, or reselect the NES cell may be determined based on the first indication information and the access prohibition parameter.

[0108] For example, if the access prohibition parameter indicates that access to the cell is not allowed (for example, the value of cellbarred is barred), and the first indication information indicates that access to the cell is allowed (not barred), the terminal device is allowed to access the NES cell.

[0109] For another example, if the access prohibition parameter indicates that access to the cell is not allowed (for example, the value of cellbarred is barred), and the first indication information indicates that access to the cell is not allowed (barred), the terminal device is not allowed to access the NES cell.

[0110] For another example, if the access prohibition parameter indicates that access to the cell is allowed (for example, the value of cellbarred is not barred), the terminal device is allowed to access the NES cell.

[0111] For another example, if the access prohibition parameter indicates that access to the cell is allowed (for example, the value of cellbarred is not barred), and the first indication information indicates that access to the cell is allowed (not barred), the terminal device is allowed to access the NES cell.

[0112] For another example, if the access prohibition parameter indicates that access to the cell is allowed (for example, the value of cellbarred is not barred), and the first indication information indicates that access to the cell is not allowed (barred), the terminal device is not allowed to access the NES cell.

[0113] For example, if the access prohibition parameter indicates that access to the cell is not allowed (for example, the value of cellbarred is barred), and the second message carries the first indication information (or the first indication information appears or exists), the terminal device is allowed to access the NES cell.

[0114] For example, if the access prohibition parameter indicates that access to the cell is not allowed (for example, the value of cellbarred is barred), and the second message does not carry the first indication information (or the first indication information does not appear or does not exist), the terminal device is not allowed to access the NES cell.

[0115] For another example, if the access prohibition parameter indicates that access to the cell is allowed (for example, the value of cellbarred is not barred), the terminal device is allowed to access the NES cell.

[0116] For example, if the access prohibition parameter indicates that access to the cell is allowed (for example, the value of cellbarred is not barred), and the second message carries the first indication information (or the first indication information appears or exists), the terminal device is allowed to access the NES cell.

[0117] For example, if the access prohibition parameter indicates that access to the cell is allowed (for example, the value of cellbarred is not barred), and the second message does not carry the first indication information (or the first indication information does not appear or does not exist), the terminal device is allowed to access the NES cell.

[0118] For example, if the access prohibition parameter indicates that access to the cell is allowed (for example, the value of cellbarred is not barred), and the second message does not carry the first indication information (or the first indication information does not appear or does not exist), the terminal device is not allowed to access the NES cell.

[0119] In some implementations, the first indication information mentioned above may further include multiple sub-information. The multiple sub-information corresponds one-to-one to multiple NES technologies (such as adaptive SSB / RACH / Paging technologies). Each sub-information in the multiple sub-information is used to indicate: whether the cell supports the NES technology corresponding to each sub-information; or whether a terminal device supporting the NES technology corresponding to each sub-information is allowed to access the cell; or whether the cell supports the NES technology corresponding to the first sub-information, where the first sub-information is one of the multiple sub-information; or whether a terminal device supporting the NES technology corresponding to the first sub-information is allowed to access the cell.

[0120] In some implementations, the use of multiple sub-information may be subject to certain conditions. For example, if a second condition is met, whether a terminal device is allowed to access an NES cell is determined based on at least part of the multiple sub-information, or whether a terminal device is allowed to access an NES cell is determined based on at least part of the first sub-information, where the second condition includes one or more of the following: the first indication information indicates that access to the cell is allowed, the first indication information indicates that access to the cell is not allowed, the second message carries the first indication information, the second message does not carry the first indication information, the first sub-information exists or appears in the first indication information, the first sub-information indicates permission, the access prohibition parameter is ignored, or the access prohibition parameter indicates permission.

[0121] In some implementations, whether a terminal device supporting a specific NES technology can access the NES cell is controlled or determined based on the sub-information corresponding to the specific NES technology; or, whether a specific terminal device can access the NES cell is controlled or determined based on the corresponding sub-information; or, whether a specific terminal device can access the NES cell is controlled or determined based on the first sub-information.

[0122] In some implementations, the first indication information mentioned above may include multiple second indication information, and the multiple second indication information corresponds one-to-one to multiple NES technologies. Each second indication information in the multiple second indication information is used to indicate: whether the cell supports the NES technology corresponding to each second indication information; or, whether the terminal device supporting the NES technology corresponding to each second indication information is allowed to access the cell; or, whether the cell supports the NES technology corresponding to the target information, the target information is one of the multiple second indication information; or, whether the terminal device supporting the NES technology corresponding to the target information is allowed to access the cell.

[0123] In some implementations, the use of multiple second indication information may be subject to certain conditions. For example, if a third condition is met, whether the terminal device is allowed to access the NES cell is determined based on at least part of the multiple second indication information, or whether the terminal device is allowed to access the NES cell is determined based on at least part of the target information, and the third condition includes one or more of the following: the first indication information indicates that access to the cell is allowed, the first indication information indicates that access to the cell is not allowed, the second message carries the first indication information, the second message does not carry the first indication information, the target information exists or appears in the first indication information, the target information indicates permission, the access prohibition parameter is ignored, and the access prohibition parameter indicates permission.

[0124] In some implementations, whether a terminal device supporting a specific NES technology can access the NES cell is controlled or determined based on the second indication information corresponding to the specific NES technology; or, whether a specific terminal device can access the NES cell is controlled or determined based on the corresponding second indication information; or, whether a specific terminal device can access the NES cell is controlled or determined based on the target information.

[0125] The following describes the embodiments of the present application in more detail with reference to specific examples. It should be noted that the following embodiments are only intended to help those skilled in the art understand the embodiments of the present application, rather than to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated. It is apparent that those skilled in the art can make various equivalent modifications or changes based on the embodiments provided, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0126] Example 1 (Method for Obtaining NES Cell Information)

[0127] 3 , the network sends NES cell information (or NES frequency information) to the terminal device (see step S310 in FIG3 ). The NES cell information includes one or more of the following:

[0128] The NES cell information can be obtained through base station indication information. For example, it can be indicated through an SIB message or a dedicated RRC message. If the NES cell information is indicated through an SIB message, it can be carried through an extension of an existing SIB message or a newly introduced SIBX message. Optionally, the terminal device obtains the NES cell information through a SIBX message sent by a cell it previously resided in, an anchor cell of the NES cell, or a cell it previously accessed.

[0129] For another example, the NES cell information may be carried in a dedicated RRC message (such as an RRC release message). Optionally, the terminal device obtains the NES cell information via a dedicated RRC message sent by a cell that the terminal device has previously accessed.

[0130] The above-mentioned NES cell information can be used by terminal devices in idle / inactive states.

[0131] After receiving the information of the NES cell, the terminal device can determine the information of the NES cell or frequency, or determine whether the NES cell exists, or determine whether it is necessary to request further information of the NES cell (such as sending an on-demand message (such as UL WUS) to request the NES cell to send SIB1, see step S320 in Figure 3).

[0132] Embodiment 1 provides a method for obtaining NES cell information, so that a terminal device can obtain NES cell information, determine whether a NES cell exists and / or request further information about the NES cell, which helps the terminal device work in the NES cell.

[0133] Example 2 (Method for controlling terminal device access in NES cell)

[0134] The terminal device receives information indicated by the network device, which is used to control the terminal device's access to the network. The information includes an existing bar parameter and / or first indication information (which may be a new access control parameter, such as a new bar parameter). As an example, the information sent by the network device to the terminal device may be called a barring indication (see step S410 in FIG. 4 ).

[0135] After receiving the information indicated by the network device, the terminal device may determine whether to access the network (see step S420 in FIG. 4 ).

[0136] Optionally, the network is an NES cell or base station. The NES cell or base station is one or more of the following: an SSB-less cell or base station, a cell using NES technology (such as a cell using or supporting adaptive SSB / RACH / paging technology), and a SIB1-less cell or base station.

[0146] For another example, when the first indication information appears or indicates that it is not allowed, and the sub-information for adaptive paging does not appear or indicates that it is not allowed, the NES terminal device can access the cell that supports or uses paging.

[0147] For another example, if the first indication information appears or indicates permission, and the sub-information for adaptive paging does not appear or indicates permission is not allowed, and the NES terminal device supports NES or SIB1-less cells, the terminal device can access the cell.

[0148] For another example, if the first indication information appears or indicates permission, and the sub-information for adaptive paging does not appear or indicates permission, and the NES terminal device supports adaptive paging, the terminal device cannot access the cell.

[0149] For another example, when the second indication information of SIB1-less appears or indicates permission, the NES terminal device can access the SIB1-less cell.

[0150] For another example, when the second indication information for adaptive paging does not appear or indicates that it is not allowed, the NES terminal device cannot access the cell that supports or uses paging.

[0151] For another example, when the second indication information for SIB1-less appears or indicates permission, an NES terminal device that supports SIB1-less can access the SIB1-less cell.

[0152] For another example, when the second indication information for adaptive paging does not appear or indicates that it is not allowed, the NES terminal device supporting adaptive paging cannot access the cell that supports or uses paging.

[0153] For another example, if the cellbarred indication is allowed and the second indication information for SIB1-less appears or indicates allowed, the NES terminal device can access the SIB1-less cell.

[0154] For another example, if cellbarred indicates permission, and the second indication information for SIB1-less appears or indicates permission, an NES terminal device that supports SIB1-less can access the SIB1-less cell.
