[0002] In some communication systems, the system messages of a cell include a Master Information Block (MIB) and System Information Blocks (SIBs).

That is, the terminal can obtain cell information or access information only by receiving two system messages (MIB and SIB1).

[0038] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application.

Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device, a flight vehicle, a vehicle user equipment (VUE), a shipborne device, a pedestrian user equipment (PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, TVs, washing machines, or furniture, etc.), a game console, a personal computer (PC), a teller machine, or a self-service machine, etc. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, reduced capability UE (RedCap UE), evolved reduced capability UE (eRedCap UE), non-terrestrial network (NTN) terminals, etc. Among them, the vehicle user equipment can also be referred to as a vehicle terminal, a vehicle controller, a vehicle module, a vehicle component, a vehicle chip, or a vehicle unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application.

[0043] The network-side device 12 may include an access network device or a core network device. Among them, the access network device may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node, etc. Among them, the base station may be referred to as Node B (NB), evolved Node B (eNB), next generation Node B (gNB), new radio Node B (NR Node B), access point, relay base station (RBS), serving base station (SBS), base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), home Node B (HNB), home evolved Node B, transmission reception point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to a specific technical term. It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0044] The core network device may include but is not limited to at least one of the following: core network node, core network function, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0045] In some embodiments, the Access Stratum (AS) of the terminal may report the obtained Public Land Mobile Network (PLMN) information to the NAS layer autonomously or based on the instructions received from the Non-Access Stratum (NAS).

[0046] Among them, during the process of the AS performing PLMN search, the terminal can, according to its own capabilities, scan all radio frequency (RF) channels one by one to find the available PLMN information. On each scanned carrier frequency, the terminal searches for the cell with the strongest signal quality and reads the system information to confirm the PLMN set to which the cell belongs (a cell can belong to multiple PLMNs). If the terminal can read one or more PLMN identifiers in the cell with the strongest signal quality mentioned above, the terminal reports each read PLMN ID to the NAS layer.

[0047] The NAS layer can notify the selected PLMN to the AS layer. The NAS layer can also provide the AS layer with an equivalent PLMN list at the same time. The AS layer can perform cell selection and reselection based on the selected PLMN and the PLMNs in the equivalent PLMN list.

[0048] Once the terminal selects a PLMN, it performs the cell selection process to select a suitable cell corresponding to the selected PLMN above for camping on.

[0049] In some embodiments, a suitable cell refers to a cell where the terminal can camp on and obtain normal services. The terminal needs to have a valid Universal Subscriber Identity Module (USIM), and the suitable cell meets the following characteristics:

[0050] The cell belongs to one of the following PLMNs of the terminal: the selected PLMN, the registered PLMN, or a PLMN in the equivalent PLMN list;

[0051] The cell meets the cell selection criteria defined by the protocol;

[0052] The cell is not barred from camping on;

[0053] The tracking area (TA) information broadcast by the cell does not belong to the forbidden TA areas.

[0054] In some embodiments, in certain cases, in order to prohibit a terminal from accessing or camping on this cell, the cell may broadcast cellBarred in the system information. If the terminal reads the system information and finds that the cellBarred Information Element (IE) is set to barred, the terminal will avoid selecting or reselecting to this cell within a certain period of time (the length of time is a preset value) in the future. When the terminal finds that cellBarred is set to barred, it will determine whether it can select or reselect to other cells operating on the frequency of this cell according to the indication of intraFreqReselection (or IFRI) in the system message. If intraFreqReselection is set to notAllowed, the terminal will avoid selecting or reselecting to other cells operating on the frequency of this cell within a certain period of time (the length of time is a preset value) in the future.

[0055] When cellBarred is set to barred, the terminal only needs to consider the intraFreqReselection IE in the system information and does not need to consider other IEs.

[0056] The above cellBarred IE and intraFreqReselection IE are respectively:

[0057] cellBarred ENUMERATED{barred,notBarred},

[0058] intraFreqReselection ENUMERATED{allowed,notAllowed}.

[0059] In some embodiments, a High Speed Dedicated Network (HSDN) cell refers to a cell that has a higher priority than other cells (non-HSDN cells) when a terminal supporting HSDN reselects cells in a high-speed moving state.

[0060] When the terminal is in a high-mobility state, a non-connected terminal (such as in the RRC_IDLE state or RRC_Inactive state) supporting HSDN should regard the HSDN cell as the highest priority (i.e., higher than the priority of any other network configuration). When the terminal supporting HSDN is not in a high-mobility state, the non-connected terminal should regard the HSDN cell as the lowest priority (i.e., lower than the priority of any other network configuration).

[0061] In some embodiments, an acceptable cell refers to a cell to which a terminal can connect to obtain limited services, such as making an emergency call, and receiving notifications from the Earthquake and Tsunami Warning System (ETWS) and the Commercial Mobile Alert Service (CMAS). Such a cell should meet the following requirements:

[0062] The cell is not prohibited from being camped on;

[0063] The cell meets the cell selection criteria defined by the protocol.

[0064] The above requirements are the minimum requirements for the terminal to initiate an emergency call in the communication network and receive ETWS and CMAS notifications.

[0065] In some embodiments, if the terminal supports voice services, if it cannot find a suitable cell to camp on and the current cell does not support IP Multimedia Subsystem (IMS) emergency calls, the terminal can perform cell selection / reselection to an acceptable cell of any radio access technology (RAT) supported by the terminal that supports emergency calls, regardless of the priority provided by the system information of the current cell.

[0066] In other words, when the terminal cannot find a suitable cell to camp on, it can choose to camp on an acceptable cell, where it can make an emergency call (i.e., initiate an emergency call).

[0067] The priority in the embodiments of the present application, unless otherwise specified, refers to the priority for cell selection or cell reselection.

[0068] It should be noted that the above embodiments are only examples in the embodiments of the present application, and the present application does not limit the content related to the above embodiments.

[0069] Next, in conjunction with the accompanying drawings, a system message receiving method, a sending method, a device, a terminal, and a device provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0070] Please refer to Figure 2 , Figure 2 which is a flowchart of a system message receiving method provided by the embodiments of the present application. As Figure 2 shown, the method includes the following steps:

[0071] Step 201: The terminal receives first system information, where the first system information includes a cell barring indication and a first indication.

[0072] Wherein, when the cell barring indication (cellBarred) is not barred (notBarred), the first indication is used to indicate at least one of the following:

[0073] Attribute information of the cell, random access information.

[0074] The above-mentioned terminal receiving the first system information may be that the terminal receives the first system information sent by a network-side device, and the network-side device may be associated with one or more cells.

[0075] Wherein, the above-mentioned cell barring indication being not barred may indicate that the cell allows the terminal (such as some terminals) to perform cell selection or reselection and then camp on the above-mentioned cell. Whether to select or not, reselect or not can be determined by the terminal or determined based on the attribute information or random access information of the cell, etc., and this is not limited.

[0076] The above-mentioned cell is the cell associated with the above-mentioned first system information.

[0077] In some embodiments, the above-mentioned first system information is the MIB, or newly defined system information.

[0078] The above-mentioned attribute information of the cell may be related attribute information indicating the cell type, communication characteristics supported by the cell, or cell sensing, etc.

[0079] The above-mentioned random access information may be information related to random access, such as resources or access methods related to random access.

[0080] In one embodiment, the first indication indicates the above-mentioned attribute information of the cell; or, the first indication indicates the above-mentioned random access information; or, the first indication indicates the above-mentioned attribute information of the cell and the above-mentioned random access information.

[0081] In the embodiments of the present application, through the above steps, the terminal can obtain at least one of the attribute information of the cell or the random access information when receiving the first system information, thereby improving the communication efficiency of the terminal.

[0082] In some embodiments, when the terminal determines not to select or reselect the above-mentioned cell, or exclude the above-mentioned cell, etc. based on the above-mentioned attribute information or random access information of the cell, the terminal does not obtain the second system information (such as SIB1) of the above-mentioned cell, thereby accelerating the cell selection or reselection process and improving the cell selection or reselection efficiency.

[0083] In the embodiments of the present application, the description is mainly based on the IE names and values in the NR system. However, for the same or similar IEs and values in different systems, they are also applicable, that is, the IEs and specific values are not regarded as limitations of the embodiments of the present application.

[0084] As an implementation manner, the attribute information of the cell is used to determine the cell selection priority or cell reselection priority of the cell.

[0085] In this implementation manner, the terminal can determine the cell selection priority or cell reselection priority of the cell based on the attribute information of the above cell. Among them, the strategy for determining the cell selection priority or cell reselection priority of the cell can adopt the strategy defined in the protocol or can be determined by the terminal itself, and this is not limited.

[0086] Since the attribute information based on the cell can be used to determine the cell selection priority or cell reselection priority of the cell, the terminal can determine the cell selection priority or cell reselection priority of the cell based on the first system information, thereby accelerating the cell selection or reselection process and improving the cell selection or reselection efficiency.

[0087] It should be noted that the above attribute information of the cell is not limited to determining the cell selection priority or cell reselection priority of the cell. For example: in some implementation manners, the terminal can directly exclude the above cell based on the attribute information of the above cell, or can directly determine to select or reselect to the above cell based on the attribute information of the above cell.

[0088] As an implementation manner, the above first indication is an intra-frequency cell reselection indication for the first frequency.

[0089] Among them, the above first frequency is the frequency where the above cell is located, or the frequency associated with the above first system information.

[0090] The intra-frequency cell reselection indication for the above first frequency can be understood as an intra-frequency cell reselection indication for the first frequency, such as an Intra-Frequency cell Reselection Indication (IFRI).

[0091] In this implementation manner, the following at least one item can be indicated by the intra-frequency cell reselection indication for the first frequency:

[0092] The attribute information of the cell, random access information.

[0093] In this way, the intra-frequency cell reselection indication field in the first system information can be reused, and a new indication field is avoided from being introduced additionally in the first system information.

[0094] It should be noted that in the embodiments of the present application, the above first indication is not limited to the first IFRI. For example, in some embodiments, it may also be an indication field added in the first system information.

[0095] As an embodiment, the attribute information of the cell includes at least one of the following:

[0096] The type information of the cell, the information of the communication characteristics supported by the cell, and the sensing information of the cell.

[0097] Among them, the above type information of the cell may be the type information in multiple types of cell type information agreed in the protocol.

[0098] In one embodiment, the type information of the cell may be the information indicating the type of the cell.

[0099] In some embodiments, the above type information of the cell may include at least one of the following:

[0100] Whether the cell is an HSDN cell;

[0101] Whether the cell is a cell free cell.

[0102] The above HSDN cell can be understood as a cell supporting the HSDN feature, that is, the cell supporting HSDN and the cell being an HSDN cell have the same meaning, and whether the cell is an HSDN cell can be understood as whether the cell supports the HSDN feature.

[0103] In this embodiment, since the type information of the cell is included, the terminal can determine the type of the cell by receiving the first system information, so that in the case where the cell type does not match the terminal or the terminal cannot camp on this type of cell, the terminal does not obtain the second system information of this cell, thereby reducing the power consumption of the terminal and improving the execution efficiency of cell selection or reselection.

[0104] For example: A terminal supporting the HSDN feature obtains the first system information of reselection candidate cells 1 and 2. When the cellBarred indication is not barred, the terminal determines whether the candidate cell is an HSDN cell according to the information indicated by the IFRI field; thus, the terminal determines the reselection priority of the candidate cell according to whether the candidate cell is an HSDN cell. For example, reselection candidate cell 1 is a high-priority cell, and reselection candidate cell 2 is a low-priority cell. If candidate cell 1 is selected as the serving cell and candidate cell 2 is not selected as the serving cell, the terminal does not obtain the second system information of this candidate cell 2. Thus, based on this mechanism, the terminal excludes the selection of this candidate cell before obtaining the second system information of the candidate cell, thereby making the execution efficiency of cell selection or reselection higher and faster.

[0105] The information on the communication characteristics supported by the above cell represents the communication characteristics supported by the above cell.

[0106] In some embodiments, the information on the communication characteristics supported by the above cell may include at least one of the following:

[0107] Whether the cell supports emergency calls;

[0108] Whether the cell supports network slicing;

[0109] Whether the cell supports Multicast / Broadcast Service (MBS);

[0110] Whether the cell supports backscatter communication;

[0111] Whether the cell supports Non Terrestrial Network (NTN) communication;

[0112] Whether the cell supports time-frequency pre-compensation via the Global Navigation Satellite System (GNSS);

[0113] Whether the network device of the cell supports linearly polarized antennas;

[0114] Whether the network device of the cell supports circularly polarized antennas;

[0115] Whether the cell supports multiple frequency bands;

[0116] Whether the cell supports discontinuous multiple frequency bands;

[0117] Whether the cell supports multi-level Synchronization Signal Block (SSB);

[0118] Whether the cell supports multiple TRPs.

[0119] Since it includes the information on the communication characteristics supported by the cell, the terminal can determine the communication characteristics supported by the cell by receiving the first system information. Thus, in the case where the communication characteristics supported by the cell do not match those of the terminal, the terminal can avoid obtaining the second system information of the cell, thereby reducing the power consumption of the terminal and improving the execution efficiency of cell selection or reselection.

[0120] For example, in the case where a suitable cell is not found by the terminal, the terminal determines a cell whose condition meets the acceptable cell condition or criterion as a reselection candidate cell; in the first system information of the candidate cell, the cellBarred is indicated as not barred; the terminal determines whether the candidate cell supports IMS emergency calls according to the information indicated by the first indication; if the candidate cell does not support emergency calls, the terminal determines that the cell is not a reselection candidate cell, or determines that the cell is the reselection candidate cell with the lowest priority. Based on this mechanism, before obtaining the second system information of the candidate cell, the terminal can determine that the cell is not a reselection candidate cell or the reselection candidate cell with the lowest priority, and does not obtain the second system information of the cell, thereby making the execution efficiency of cell selection or reselection higher and the speed faster.

[0121] For another example, the terminal determines whether the current cell supports the MBS service based on the above first indication. If the MBS service is being applied, the terminal will preferentially select a cell that supports the MBS service for residence.

[0122] For another example, the terminal determines whether the current cell supports network slicing based on the above first indication. A terminal that supports network slicing will preferentially select a cell that supports network slicing for residence.

[0123] For another example, the terminal determines whether the current cell supports backscatter communication based on the above first indication. A terminal that supports backscatter will preferentially select a cell that supports backscatter for residence, or a terminal that only supports backscatter will select a cell that supports backscatter for residence.

[0124] For another example, the terminal determines whether the current cell supports non-terrestrial network communication based on the above first indication. A terminal that supports NTN will preferentially select a cell that supports NTN for residence, or a terminal that only supports NTN will select a cell that supports NTN for residence.

[0125] For another example, the terminal determines whether the current cell supports time-frequency pre-compensation (including pre-compensation based on GNSS) based on the above first indication. A terminal that supports time-frequency pre-compensation through GNSS will preferentially select a cell that supports time-frequency pre-compensation through GNSS for residence.

[0126] For another example, the terminal determines whether the current cell supports a linear polarization antenna or a circular polarization antenna based on the above first indication. A terminal that supports a linear polarization antenna will preferentially select a cell that supports a linear polarization antenna for residence, and a terminal that supports a circular polarization antenna will preferentially select a cell that supports a circular polarization antenna for residence.

[0127] For another example: The terminal determines whether the current cell supports left-handed or right-handed circularly polarized antennas based on the above first indication. For example, a terminal that supports a left-handed circularly polarized antenna will preferentially select a cell that supports a left-handed circularly polarized antenna for residence, and a terminal that supports a right-handed circularly polarized antenna will preferentially select a cell that supports a right-handed circularly polarized antenna for residence.

[0128] For another example: The terminal determines whether the current cell supports multi-band frequency aggregation based on the above first indication. For example, a terminal that supports multi-band frequency aggregation will preferentially select a cell that supports multi-band frequency aggregation for residence.

[0129] For another example: The terminal determines whether the current cell supports discontinuous multi-band frequency aggregation based on the above first indication. For example, a terminal that supports discontinuous multi-band frequency aggregation will preferentially select a cell that supports discontinuous multi-band frequency aggregation for residence.

[0130] For another example: The terminal determines whether the current cell supports multi-level SSB based on the above first indication. For example, a terminal that supports multi-level SSB will preferentially select a cell that supports multi-level SSB for residence.

[0131] For another example: The terminal determines whether the current cell is a cell free cell or multi-TRP based on the above first indication. For example, a terminal that supports a cell free cell or multi-TRP will preferentially select a cell that supports a cell free cell or multi-TRP for residence.

[0132] It should be noted that in the embodiments of the present application, when the cellBarred indication in the first system information is not barred, the first indication in the first system information can also be used to indicate other characteristics of this cell. The other characteristics can be used by the terminal for cell selection and reselection to determine whether the cell characteristics match its own capabilities or states (such as high or low moving speed), so as to determine whether the cell can be used as a reselection candidate cell or the priority level of the cell when it is used as a reselection candidate cell. Here, the priority level refers to the relative level of the matching cell compared to the non-matching cell.

[0133] The above-mentioned cell sensing information can be used to indicate the support information of the above-mentioned cell for sensing.

[0134] In one implementation, the cell sensing information is information related to the sensing characteristics of the cell, or the cell sensing information is information indicating the sensing characteristics of the cell.

[0135] In some implementations, the above-mentioned cell sensing information may include at least one of the following:

[0136] Whether the cell supports sensing;

[0137] The sensing modes supported by the cell;

[0138] The sensing modes not supported by the cell;

[0139] The sensing service types supported by the cell;

[0140] The sensing service types not supported by the cell;

[0141] The sensing function types supported by the cell;

[0142] The sensing function types not supported by the cell;

[0143] The sensing waveforms supported by the cell;

[0144] The sensing waveforms not supported by the cell;

[0145] The sensing signals supported by the cell;

[0146] The sensing signals not supported by the cell.

[0147] Whether the above cell supports sensing can be whether the cell supports communication-sensing integration, or it can simply indicate whether it supports sensing.

[0148] In the embodiments of this application, communication-sensing integration includes 6 sensing modes, as Figure 3 shown, which are respectively: (1) Base station (BS) monostatic radar, that is, the base station transmits and receives by itself; (2) BS bistatic radar, that is, base station A transmits and base station B receives; (3) BS-UE bistatic radar, that is, the base station transmits and the terminal receives; (4) UE-BS bistatic radar, that is, the terminal transmits and the base station receives; (5) UE monostatic radar, that is, the terminal transmits and receives by itself; (6) UE bistatic radar, that is, terminal A transmits and terminal B receives.

[0149] Among them, Mode (1) and Mode (5) are monostatic sensing where the transceiver is located at the same position, which is easy to achieve transceiver clock synchronization, but requires the base station / terminal to have full-duplex capabilities. The other four sensing modes are bistatic sensing with separated transceivers. Due to the spatial separation of the transmitter and receiver, this mode does not require the transceiver to have full-duplex capabilities. For distance / delay measurement-based sensing, clock synchronization between the transmitter and receiver needs to be solved. In Mode (2), a base station sends a sensing signal and another base station receives the sensing signal for sensing measurement. Modes (3) and (4) are based on the downlink and uplink for sensing respectively. Potentially, downlink or uplink reference signals can be reused, or new sensing reference signals can be used, or communication signals carrying data can also be reused for sensing, but the communication data needs to be decoded before sensing processing. Mode (6) is based on sidelink for sensing. Potentially, the sensing signal can also be based on sidelink reference signals, new sensing reference signals, or reused sidelink communication data signals. Considering widely distributed terminals, Mode (3) can shorten the propagation path length of the sensing channel by selecting appropriate terminals, thereby improving the sensing signal-to-noise ratio (SNR).

[0150] The above supported or unsupported sensing modes can include the following four types:

[0151] (1) The base station sends and receives by itself; (2) Base station A sends and base station B receives; (3) The base station sends and the terminal receives; (4) The terminal sends and the base station receives. Use 1 bit to support or not support the above four types, or use 4 bits to indicate which sensing modes the cell supports / does not support. For example, the bitmap 1010 represents that the cell supports the first and third sensing modes above and does not support the second and fourth sensing modes;

[0152] The above supported or unsupported sensing modes of the cell can also be specific sensing modes supported or not supported by the cell, such as whether the cell supports the sensing mode of the base station sending and receiving by itself; since there is interference between the transmitted signal and the echo signal of the transmitted signal in the sensing mode of the base station sending and receiving by itself, the base station needs to have a certain degree of self-interference cancellation ability or full-duplex ability, which requires a relatively high requirement for the base station; the other three sensing modes do not require the base station to have self-interference cancellation ability or full-duplex ability. Therefore, 1 bit can be used to indicate whether the cell supports the sensing mode of the base station sending and receiving by itself. Optionally, the other three base station-related sensing modes are default supported by the cell.

[0153] The above supported or unsupported sensing service types of the cell can include at least one of the following:

[0154] The above supported or unsupported radar detection services of the cell include: radar speed measurement, radar distance measurement, radar angle measurement, and radar imaging;

[0155] The above-mentioned cell supports or does not support user positioning and tracking services;

[0156] The above-mentioned cell supports or does not support environmental reconstruction services, including: terrain and landform reconstruction, building surface reconstruction;

[0157] The above-mentioned cell supports or does not support weather and / or air quality detection services, which may include: rainfall detection, humidity detection, particulate matter detection, snowfall detection;

[0158] The above-mentioned cell supports or does not support pedestrian / vehicle flow detection services;

[0159] The above-mentioned cell supports or does not support health monitoring services, which may include: heart rate monitoring, respiration detection;

[0160] The above-mentioned cell supports or does not support action recognition services, which may include: gesture recognition, posture recognition, intrusion detection.

[0161] In some embodiments, the above-mentioned sensing service types may be combined for indication to save the overhead of the first system information.

[0162] The above-mentioned cell supports or does not support the following at least one of the sensing function types:

[0163] The above-mentioned cell supports or does not support radar detection, including: radar speed measurement, radar ranging, radar angle measurement, radar imaging;

[0164] The above-mentioned cell supports or does not support user positioning and tracking;

[0165] The above-mentioned cell supports or does not support environmental reconstruction, including: terrain and landform reconstruction, building surface reconstruction;

[0166] The above-mentioned cell supports or does not support weather and / or air quality detection, which may include: rainfall detection, humidity detection, particulate matter detection, snowfall detection;

[0167] The above-mentioned cell supports or does not support pedestrian / vehicle flow detection;

[0168] The above-mentioned cell supports or does not support health monitoring, which may include: heart rate monitoring, respiration detection;

[0169] The above-mentioned cell supports or does not support action recognition, which may include: gesture recognition, posture recognition, intrusion detection.

[0170] In some embodiments, the above-mentioned sensing function types may be combined for indication to save the overhead of the first system information.

[0171] The above-mentioned cell supports or does not support the following at least one of the sensing waveforms:

[0172] Frequency Modulated Continuous Wave (FMCW), Orthogonal Frequency Division Multiplexing (OFDM), Single-carrier Frequency-Division Multiple Access (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Frequency Modulated Continuous Wave (FMCW), pulse signals, or other waveforms specifically designed for sensing.

[0173] The sensing signals supported or not supported by the above cell may include at least one of the following:

[0174] FMCW signals, OFDM signals, Orthogonal Time Frequency Space (OTFS) signals, Linear Frequency Modulation (LFM) signals, simple pulse train signals, phase-coded radar signals, or other signals specifically designed for sensing.

[0175] Since the sensing information of the cell is included, the terminal can determine the sensing information of the cell by receiving the first system information. In the case where the sensing information of the cell does not match the terminal, the terminal does not obtain the second system information of the cell, so as to reduce the power consumption of the terminal and improve the execution efficiency of cell selection or reselection.

[0176] As an implementation manner, the random access information includes:

[0177] Whether to enable a flexible Random Access CHannel Occasion (RO).

[0178] Whether to enable the flexible RO mentioned above can be whether the flexible RO is enabled, or to enable or disable the use of the flexible RO.

[0179] Whether to enable the flexible RO mentioned above can be to indicate whether the terminal enables the flexible RO or to indicate whether the network-side device enables the flexible RO.

[0180] In this embodiment, since the random access information includes whether to enable the flexible RO as described above, the characteristic of the high transmission frequency of the first system information can be utilized to implement the dynamic enabling of the flexible RO through the first system information, and the flexible RO is enabled or disabled to improve the flexibility of random access.

[0181] In the embodiments of the present application, the content indicated by the first indication in the above-mentioned first system information is not limited. For example, when the cell prohibition indication in the first system information is not prohibited, the above-mentioned first indication may indicate some information that often changes, or may indicate any other information carried in the second system information that needs to be considered during the cell selection and reselection process. In this way, this information is placed in the first system information, and the terminal can filter out some candidate cells or determine the priorities of the candidate cells, so as to avoid the terminal from reading the second system information of the corresponding cell or the second system information of low-priority cells, and the cell selection or reselection process can be accelerated.

[0182] As an embodiment, when it is determined based on the attribute information of the cell that the cell meets the preset conditions, the terminal preferentially selects or reselects the cell; or,

[0183] When it is determined based on the attribute information of the cell that the cell does not meet the preset conditions, the terminal preferentially selects or reselects other cells other than the cell.

[0184] Among them, the above-mentioned preset conditions may be conditions agreed upon by the protocol, configured by the network side, or preset by the terminal.

[0185] In some embodiments, the above-mentioned preset conditions may include at least one of the following:

[0186] The priority of the cell is higher than that of other cells;

[0187] The attribute information of the cell matches the capabilities of the terminal;

[0188] The attribute information of the cell matches the mobility state of the terminal;

[0189] The attribute information of the cell matches the attributes of the potential services of the terminal.

[0190] Among them, the priority of the above-mentioned cell being higher than that of other cells may mean that the priority of the above-mentioned cell is higher than that of other cells searched by the terminal.

[0191] The matching of the attribute information of the above-mentioned cell with the capabilities of the terminal may be that the terminal supports the communication characteristics supported by the cell represented by the attribute information, or it may be that the terminal supports the sensing mode, sensing service type, sensing function type, sensing waveform, or sensing signal, etc., supported by the cell represented by the attribute information. Or, it may be that the terminal supports the type of the cell represented by the attribute information, etc.

[0192] The matching of the attribute information of the above-mentioned cell with the mobility state of the terminal may be that the mobility state of the terminal matches the communication characteristics, sensing mode, sensing service type, or sensing function type supported by the cell represented by the attribute information. Or, it may be that the mobility state of the terminal matches the type of the cell represented by the attribute information, etc. For example: The attribute information indicates that the cell is an HSDN cell (or it can be understood that the attribute information indicates that the cell supports HSDN), and the mobility state of the terminal supporting the HSDN characteristic is high-speed movement. Thus, these two match; Another example: The attribute information indicates that the cell is a non-HSDN cell (or it can be understood that the attribute information indicates that the cell does not support HSDN), and the mobility state of the terminal supporting the HSDN characteristic is non-high-speed movement. Thus, these two match.

[0193] The matching of the attribute information of the above-mentioned cell with the attributes of the potential services of the terminal may be that the potential services of the terminal can be transmitted in this cell. For example: The potential services of the terminal include sensing services, and the attribute information indicates that this cell supports sensing. Thus, these two match; Another example: The potential services of the terminal include MBS services, and the attribute information indicates that this cell supports MBS. Thus, these two match.

[0194] The above-mentioned preferential selection or reselection of the cell may be that the terminal preferentially uses this cell as the serving cell or the resident cell, or preferentially obtains the second system information of this cell.

[0195] The above-mentioned preferential selection or reselection of other cells outside the cell may be that other cells outside this cell are preferentially used as the serving cell or the resident cell, or the second system information of other cells outside this cell is preferentially obtained, and this cell can be excluded and the second system information of this cell is not obtained.

[0196] The other cells outside the above-mentioned cell may be one or more cells outside the cell.

[0197] In the above embodiments, since the cell is preferentially selected or reselected when the cell meets the preset conditions, it is possible to preferentially select or reselect a cell that meets the above preset conditions, thereby improving the reliability and efficiency of cell selection or reselection. In addition, since other cells outside the cell are preferentially selected or reselected when the cell does not meet the preset conditions, the reading of some second system information is reduced, so as to improve the efficiency of cell selection or reselection and reduce the reception power consumption.

[0198] In some embodiments, when the above cell meets the above preset conditions, the terminal has a high reselection priority for this cell; otherwise, it is regarded as having a low reselection priority. For example: when the attributes of the cell match the terminal capabilities / services, etc., the terminal regards this cell as having a high reselection priority; otherwise, it is regarded as having a low reselection priority. Among them, the above cell may be a neighboring cell.

[0199] For a cell whose signal quality meets the reselection conditions, the terminal preferentially starts from the cell with the highest reselection priority, reads the second system information of the cell (such as SIB 1), and determines whether it can camp on this cell; if it can camp, the current reselection process ends; otherwise, it tries the next cell whose signal quality meets the reselection conditions; and so on in a loop.

[0200] In this way, the terminal can obtain the reselection priority information through the first system information, thereby preferentially reading the second system information of the high-priority cell (if the high-priority cell meets the reselection conditions, there is no need to read the second system information of the low-priority cell). It avoids the situation that after reading the second system information, it is found that the reselection priority of the cell corresponding to the read second system information is low, and it is necessary to continue reading the second system information of other candidate cells to select a cell with a high reselection priority, shortening the duration of the cell reselection process and improving the efficiency of the cell reselection process.

[0201] Optionally, when the terminal preferentially selects or reselects the cell, the terminal preferentially reads the second system information of the cell. When it is determined based on the second system information that the cell is a serving cell or a resident cell, the terminal no longer reads the second system information of other cells; or,

[0202] The terminal preferentially reads the second system information of other cells outside the cell. When it is determined based on the second system information of the other cells that the other cells are serving cells or resident cells, the terminal does not read the second system information of the cell.

[0203] Among them, the above second system information may be second system information or other second system information, which is not limited thereto.

[0204] In this embodiment, when the terminal determines that the above cell is the serving cell based on the second system information, the terminal no longer reads the second system information of other cells, thereby saving the resources of the terminal. When the terminal determines that other cells are the serving cells based on the second system information of other cells, the terminal does not read the second system information of the above cell, thereby saving the resources of the terminal.

[0205] Optionally, when the terminal preferentially selects or reselects the above cell, and the terminal reads the second system information of the above cell, the second system information includes: indication information indicating that the above cell is prohibited from accessing or camping.

[0206] Among them, the above second system information may be an SIB, such as SIB1.

[0207] The above situation where the terminal preferentially selects or reselects the above cell, and the terminal reads the second system information of the above cell means that: the cell prohibition indication in the above first system information is not prohibited, and based on the attribute information of the above cell, it is determined that the cell meets the preset conditions, the terminal preferentially selects or reselects the above cell, and preferentially reads the second system information of the above cell.

[0208] In this embodiment, it can be realized that when the first system information indicates not prohibited, the second system information indicates prohibited access or prohibited camping, so as to improve the flexibility of cell access or camping management.

[0209] In some embodiments, the above indication information may be to indicate to the target terminal that the cell is prohibited from accessing or camping, that is, the above indication information indicates that the above cell is prohibited from accessing or camping for the target terminal. In this way, differential management of the cell can be realized, that is, some terminals are allowed to access, and some other terminals are prohibited from accessing or camping, so as to improve the flexibility of cell access or camping management.

[0210] Among them, the above target terminal may be a terminal agreed by the protocol or indicated by the network side, and may also be called a specific terminal. The above target terminal includes but is not limited to at least one of the following:

[0211] RedCap terminal, eRedCap terminal, NTN terminal.

[0212] It should be noted that the above embodiment does not limit that the above indication information is indicated to the target terminal. For example: in some scenarios or situations, the terminal affected by the above indication information may also not be limited, that is, it takes effect for all terminals.

[0213] In some embodiments, the above second system information further includes a second indication, and the second indication is used to indicate whether to allow intra-frequency cell reselection within the first frequency.

[0214] The first frequency above is the frequency where the cell is located, or the frequency associated with the second system information.

[0215] Among them, the second indication above may be IFRI.

[0216] In this embodiment, by introducing a second indication in the second system information, it is possible to indicate whether intra-frequency reselection is allowed through the second indication, so that the terminal can perform similar or the same processing on the second indication in the second system information based on the processing method of the first indication in the first system information, thereby reducing the complexity of the terminal.

[0217] The second indication above indicating whether intra-frequency cell reselection within the first frequency is allowed may be to indicate whether a terminal prohibited from accessing or prohibited from camping on by the second system information is allowed to perform intra-frequency reselection within the first frequency, such as indicating whether the target terminal is allowed to perform intra-frequency reselection within the first frequency.

[0218] For example: when the cellBarred indication in the first system information is not barred, some information in the second system information is also used to indicate to the (target) terminal that the cell should be regarded as barred for the (target) terminal. At this time, in some mechanisms defined by the protocol, after the terminal obtains the second system information, it then determines whether it is allowed intra-frequency reselection according to the first indication in the first system information. If the first indication in the first system information has been used for other information indication, then a second indication can be introduced in the second system information to indicate whether a barred terminal is allowed to perform intra-frequency reselection.

[0219] As an implementation, when the cell barred indication in the first system information is barred, the first indication is used to indicate whether intra-frequency cell reselection within the first frequency is allowed.

[0220] In this embodiment, it is possible to make the first indication in the first system information indicate different contents when the cell barred indication is barred and not barred, so as to indicate more useful information to the terminal through the first system information.

[0221] It should be noted that the various embodiments provided in the embodiments of the present application can be implemented independently or in combination with each other. For example: when the cellBarred indication in the first system information is not barred, the first indication in the first system information indicates the reselection required information, specifically indicating at least one of the following:

[0222] Whether the current cell supports HSDN;

[0223] Whether the current cell supports emergency calls;

[0224] Whether the current cell supports network slicing;

[0225] Whether the current cell supports MBS, etc.;

[0226] Whether the current cell supports backscatter communication;

[0227] Whether the current cell supports non-terrestrial network communication;

[0228] Whether the current cell supports pre-compensation of time and frequency through GNSS;

[0229] Whether the network device of the current cell supports linear polarization antennas or circular polarization antennas (left-handed or right-handed polarization);

[0230] Whether the current cell supports multiple frequency bands (bands);

[0231] Whether the current cell supports discontinuous multiple bands;

[0232] Whether the current cell supports multi-level SSB, etc.;

[0233] Whether the current cell is a cell-free cell;

[0234] Whether the current cell supports multiple TRPs.

[0235] So that before the terminal reads the second system information of the candidate cell, as many cells that do not meet the reselection conditions as possible are excluded, the cell reselection process is accelerated, and the cell reselection efficiency is improved.

[0236] In the embodiment of the present application, the terminal receives first system information, and the first system information includes a cell prohibition indication and a first indication; wherein, when the cell prohibition indication is not prohibited, the first indication is used to indicate at least one of the following: the attribute information of the cell, random access information.
