[0045] The network-side device 12 may include an access network device or a core network device, wherein 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. Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the 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 (homeevolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the relevant field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary.

[0047] In some embodiments, the access stratum (AS) of the terminal may report the acquired public land mobile network (PLMN) information to the non-access stratum (NAS) layer autonomously or based on instructions received from the NAS layer.
[0048] During the AS's PLMN search, the terminal can, based on its capabilities, scan all radio frequency (RF) channels one by one to locate available PLMN information. On each scanned carrier frequency, the terminal searches for the cell with the strongest signal quality and reads system information to confirm the PLMN set to which the cell belongs (a cell can belong to multiple PLMNs). If the terminal is able to read one or more PLMN identifiers in the cell with the strongest signal quality, it reports each PLMN ID to the NAS layer.
[0049] The NAS layer can notify the AS layer of the selected PLMN. The NAS layer can also provide the AS layer with an equivalent PLMN list. The AS layer can perform cell selection and reselection based on the selected PLMN and the PLMNs in the equivalent PLMN list.
[0050] Once the terminal selects a PLMN, it performs a cell selection process to select a suitable cell corresponding to the selected PLMN to camp on.
[0051] In some embodiments, a suitable cell refers to a cell in which the terminal can reside and obtain normal service. The terminal needs to have a valid Universal Subscriber Identity Module (USIM), and the suitable cell must meet the following characteristics:
[0052] The cell belongs to the following PLMNs of the terminal: the selected PLMN or the registered PLMN or a PLMN in the equivalent PLMN list;
[0053] The cell meets the cell selection criteria defined by the protocol;
[0054] The cell is not barred;
[0055] The tracking area (TA) information broadcast by the cell does not belong to the forbidden tracking areas (Forbidden Tracking Areas).
[0056] In some embodiments, in order to prohibit the terminal from accessing or residing in the cell in certain circumstances, the cell may broadcast cell barring (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 the cell for a period of time in the future (the time length is a preset value). When the terminal finds that cellBarred is set to barred, it will determine whether it can select or reselect to other cells operating at the frequency point where the cell is located based on the indication of intraFreqReselection (IFRI) in the system message. If intraFreqReselection is set to notAllowed, the terminal will avoid selecting or reselecting to other cells operating at the frequency point where the cell is located for a period of time in the future (the time length is a preset value).
[0057] 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.
[0058] The above cellBarredIE and intraFreqReselection IE are respectively:
[0059] cellBarred ENUMERATED{barred,notBarred},
[0060] intraFreqReselection ENUMERATED{allowed,notAllowed}.
[0061] 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 performs cell reselection when the terminal is in a high-speed mobile state.
[0062] When the terminal is in a high mobility state, a terminal in a non-connected state (such as in RRC_IDLE state or RRC_Inactive state) that supports HSDN should consider the HSDN cell as the highest priority (i.e., higher than the priority configured by any other network). When the terminal that supports HSDN is not in a high mobility state, the non-connected terminal should consider the HSDN cell as the lowest priority (i.e., lower than the priority configured by any other network).
[0063] In some embodiments, an acceptable cell is a cell to which a terminal can connect to obtain limited services, such as making emergency calls and receiving Earthquake and Tsunami Warning System (ETWS) and Commercial Mobile Alert Service (CMAS) notifications. Such a cell should meet the following requirements:
[0064] The cell is not prohibited from residing;
[0065] The cell meets the cell selection criteria defined by the protocol.
[0066] The above requirements are the minimum requirements for a terminal to initiate an emergency call in the communication network and receive ETWS and CMAS notifications.
[0067] In some embodiments, if the terminal supports voice services, if it does not 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 terminal-supported Radio Access Technology (RAT) that supports emergency calls, regardless of the priority provided by the system information of the current cell.
[0068] 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 (ie, initiate an emergency call).
[0069] Unless otherwise specified, the priorities in the embodiments of the present application refer to the priorities used for cell selection or cell reselection.
[0070] It should be noted that the above embodiments are merely examples of the embodiments of the present application, and the embodiments of the present application do not limit the contents related to the above embodiments.
[0071] In the following, in conjunction with the accompanying drawings, a system message receiving method, sending method, apparatus, terminal and device provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.
[0072] Please refer to FIG2 , which is a flowchart of a method for receiving a system message provided in an embodiment of the present application. As shown in FIG2 , the method includes the following steps:
[0073] Step 201: The terminal receives first system information, where the first system information includes a cell barring indication and a first indication.
[0074] Wherein, when the cell barring indication (cellBarred) is not barred (notBarred), the first indication is used to indicate at least one of the following:
[0075] Cell attribute information and random access information.
[0076] The terminal receiving the first system information may be the terminal receiving the first system information sent by a network side device, and the network side device may be associated with one or more cells.
[0077] Among them, the above-mentioned cell prohibition indication of not prohibiting may indicate that the cell allows the terminal (such as some terminals) to perform cell selection or reselection and then reside in the above-mentioned cell. The specific selection or non-selection, reselection or non-reselection may be determined by the terminal or based on the cell's attribute information or random access information, etc., and is not limited to this.
[0078] The above-mentioned cell is the cell associated with the above-mentioned first system information.
[0079] In some implementations, the first system information is MIB, or newly defined system information.
[0080] The attribute information of the above-mentioned cell may be related attribute information such as the cell type, communication characteristics supported by the cell, or cell perception.
[0081] The random access information may be information related to random access, such as resources related to random access or access methods.
[0082] In one implementation, the first indication indicates the attribute information of the cell; or, the first indication indicates the random access information; or, the first indication indicates the attribute information of the cell and the random access information.
[0083] In the embodiment of the present application, the above steps can achieve that the terminal can obtain at least one of the attribute information of the cell or the random access information by receiving the first system information, thereby improving the communication efficiency of the terminal.
[0084] In some embodiments, when the terminal determines not to select or reselect the above-mentioned cell, or excludes the above-mentioned cell based on the attribute information or random access information of the above-mentioned 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.
[0085] In the embodiments of the present application, the description is mainly based on the IE names and values in the NR system, but IEs and values with the same or similar purposes in different systems are also applicable, that is, IEs and specific values are not regarded as limitations of the embodiments of the present application.
[0086] 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.
[0087] In this implementation, the terminal can determine the cell selection priority or cell reselection priority of a cell based on the attribute information of the above-mentioned cell. The strategy for determining the cell selection priority or cell reselection priority of a cell can adopt the strategy defined in the protocol, or it can be decided by the terminal itself, and there is no limitation on this.
[0088] Since the cell-based attribute information 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.
[0089] It should be noted that the attribute information of the above-mentioned cell is not limited to determining the cell selection priority or cell reselection priority of the cell. For example, in some embodiments, the terminal can directly exclude the above-mentioned cell based on the attribute information of the above-mentioned cell, or can directly determine to select or reselect the cell based on the attribute information of the above-mentioned cell.
[0090] As an implementation manner, the above-mentioned first indication is a first intra-frequency cell reselection indication.
[0091] The first frequency is the frequency of the cell, or the frequency associated with the first system information.
[0092] The first intra-frequency cell reselection indication may be understood as an intra-frequency cell reselection indication of the first frequency, such as an intra-frequency cell reselection indication (IFRI).
[0093] In this implementation, the first intra-frequency cell reselection indication may indicate at least one of the following:
[0094] Cell attribute information and random access information.
[0095] In this way, the intra-frequency cell reselection indication field in the first system information can be reused, avoiding the introduction of a new indication field in the first system information.
[0096] It should be noted that, in the embodiment of the present application, the first indication is not limited to the first IFRI. For example, in some implementations, it may also be an indication field added to the first system information.
[0097] In one embodiment, the attribute information of the cell includes at least one of the following:
[0098] The type information of the cell, information on the communication characteristics supported by the cell, and perception information of the cell.
[0099] The cell type information may be type information among a plurality of cell type information agreed in the protocol.
[0100] In one implementation, the cell type information may be information indicating the type of the cell.
[0101] In some implementations, the cell type information may include at least one of the following:
[0102] Whether the cell is a HSDN cell;
[0103] Whether the cell is a cell-free cell.
[0104] The above-mentioned HSDN cell can be understood as a cell that supports HSDN features, that is, the cell supporting HSDN and the cell being an HSDN cell have the same meaning, and whether a cell is an HSDN cell can be understood as whether the cell supports HSDN features.
[0105] In this embodiment, since the cell type information is included, the terminal can determine the cell type by receiving the first system information, so that when the cell type does not match the terminal or the terminal cannot reside in a cell of this type, the second system information of the cell is not obtained, thereby reducing the energy consumption of the terminal and improving the execution efficiency of cell selection or reselection.
[0106] For example, a terminal supporting the HSDN feature obtains the first system information of candidate cells 1 and 2 for reselection. If the cellBarred indication is "not barred," the terminal determines whether the candidate cell is an HSDN cell based on the information indicated by the IFRI field. Thus, the terminal determines the reselection priority of the candidate cells based on whether the candidate cells are HSDN cells. 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 candidate cell 2. Thus, based on this mechanism, the terminal excludes the candidate cell from selection before obtaining its second system information, thereby making cell selection or reselection more efficient and faster.
[0107] The information on the communication characteristics supported by the cell indicates the communication characteristics supported by the cell.
[0108] In some implementations, the information on the communication characteristics supported by the cell may include at least one of the following:
[0109] whether the cell supports emergency calls;
[0110] whether the cell supports network slicing;
[0111] Whether the cell supports Multicast / Broadcast Service (MBS);
[0112] Whether the cell supports backscatter communication;
[0113] Whether the cell supports non-terrestrial network (NTN) communication;
[0114] Whether the cell supports time and frequency pre-compensation via the Global Navigation Satellite System (GNSS);
[0115] Whether the network equipment of the cell supports linear polarization antennas;
[0116] Whether the network equipment of the cell supports circularly polarized antennas;
[0117] whether the cell supports multiple frequency bands;
[0118] whether the cell supports non-contiguous multiple frequency bands;
[0119] Whether the cell supports multi-level synchronization signal blocks (SSB);
[0120] Whether the cell supports multiple TRPs.
[0121] Since the information includes the communication characteristics supported by the cell, the terminal can determine the communication characteristics supported by the cell by receiving the first system information. Therefore, when the communication characteristics supported by the cell do not match the terminal, the second system information of the cell is not obtained, thereby reducing the energy consumption of the terminal and improving the execution efficiency of cell selection or reselection.
[0122] For example, if a terminal fails to find a suitable cell, it identifies a cell that meets the acceptable cell conditions or criteria as a candidate cell for reselection. In the first system information of the candidate cell, the cellBarred indication is "not barred." The terminal determines whether the candidate cell supports IMS emergency calls based on 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 candidate cell for reselection, or determines that the cell is the lowest-priority candidate cell for reselection. Based on this mechanism, before obtaining the second system information of the candidate cell, the terminal can determine that the cell is not a candidate cell for reselection or the lowest-priority candidate cell for reselection, and does not obtain the second system information of the cell, thereby making cell selection or reselection more efficient and faster.
[0123] For another example, the terminal determines whether the current cell supports the MBS service based on the first indication. If the MBS service is being used, the terminal will preferentially select the cell supporting the MBS service for residency.
[0124] For another example: the terminal determines whether the current cell supports network slicing based on the above-mentioned first indication. If the terminal supports network slicing, it will give priority to staying in the cell that supports network slicing.
[0125] For another example: the terminal determines whether the current cell supports backscatter communication based on the first indication. For example, a terminal that supports backscatter will preferentially select a cell that supports backscatter to reside in, or a terminal that only supports backscatter will select a cell that supports backscatter to reside in.
[0126] For another example, the terminal determines whether the current cell supports non-terrestrial network communication based on the first indication. For example, a terminal supporting NTN will preferentially select a cell supporting NTN for residency, or a terminal supporting only NTN will select a cell supporting NTN for residency.
[0127] For another example: the terminal determines whether the current cell supports time and frequency pre-compensation (including pre-compensation based on GNSS) based on the above first indication. If the terminal supports time and frequency pre-compensation through GNSS, it will give priority to staying in the cell that supports time and frequency pre-compensation through GNSS.
[0128] For another example: the terminal determines whether the current cell supports linear polarization antennas or circular polarization antennas based on the above first indication. For example, a terminal that supports linear polarization antennas will give priority to supporting linear polarization antennas for resident, and a terminal that supports circular polarization antennas will give priority to supporting circular polarization antennas for resident.
[0129] For another example: the terminal determines whether the current cell supports left-hand or right-hand circularly polarized antennas based on the above-mentioned first indication. For example, a terminal that supports left-hand circularly polarized antennas will give priority to staying in a cell that supports left-hand circularly polarized antennas, and a terminal that supports right-hand circularly polarized antennas will give priority to staying in a cell that supports right-hand circularly polarized antennas.
[0130] For another example, the terminal determines whether the current cell supports multi-band frequency aggregation based on the first indication. For example, a terminal that supports multi-band frequency aggregation will preferentially select a cell that supports multi-band frequency aggregation for camping.
[0131] For another example, the terminal determines whether the current cell supports discontinuous multi-band frequency aggregation based on the first indication. If the terminal supports discontinuous multi-band frequency aggregation, it will preferentially select the cell supporting discontinuous multi-band frequency aggregation to camp on.
[0132] For another example: the terminal determines whether the current cell supports multi-level SSB based on the above-mentioned first indication. If the terminal supports multi-level SSB, it will give priority to choosing a cell supporting multi-level SSB to reside in.
[0133] For another example: the terminal determines whether the current cell is a cell free cell or a multi-TRP based on the above first indication. If the terminal supports cell free cells or multi-TRPs, it will give priority to supporting cell free cells or multi-TRP cells for residence.
[0134] It should be noted that, in an embodiment 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 the cell. Other characteristics can be used by terminals performing cell selection and reselection to determine whether the cell characteristics match their own capabilities or status (such as mobile speed) to determine whether the cell can be used as a candidate cell for reselection or the priority of the cell when it is used as a candidate cell for reselection, where the priority here refers to the relative priority of the matching cell compared to the non-matching cell.
[0135] The perception information of the above-mentioned cell can be used to indicate the support information of the above-mentioned cell for perception.
[0136] In one implementation, the cell perception information is information related to the cell perception characteristics, or the cell perception information is information indicating the cell perception characteristics.
[0137] In some implementations, the cell perception information may include at least one of the following:
[0138] whether the cell supports sensing;
[0139] sensing modes supported by the cell;
[0140] A sensing mode not supported by the cell;
[0141] A sensing service type supported by the cell;
[0142] A sensing service type not supported by the cell;
[0143] The type of sensing function supported by the cell;
[0144] A type of sensing function not supported by the cell;
[0145] sensing waveforms supported by the cell;
[0146] A sensing waveform not supported by the cell;
[0147] a perception signal supported by the cell;
[0148] A perception signal not supported by the cell.
[0149] Whether the above-mentioned cell supports perception may be whether the cell supports communication perception integration, or may simply indicate whether perception is supported.
[0150] In the embodiment of the present application, the interawareness integration includes six perception modes, as shown in FIG3 , namely: (1) Base station (BS) monostatic radar (monostatic), that is, the base station transmits and receives by itself; (2) BS bistatic radar (bistatic), 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.
[0151] Among them, mode (1) and mode (5) are single-base sensing with the transmitter and receiver located at the same location, which is easy to achieve transmission and reception clock synchronization, but requires the base station / terminal to have full-duplex capability. The other four sensing modes are dual-base sensing with separate transmission and reception. Due to the spatial separation of the transmitter and receiver, this mode does not require the transceiver to have full-duplex capability. For distance / delay measurement type sensing, the clock synchronization between the transmitter and receiver must be solved. Mode (2) is a situation where one base station sends a sensing signal and the other base station receives the sensing signal for sensing measurement. Mode (3) and mode (4) are based on downlink and uplink sensing respectively. It is possible to reuse downlink or uplink reference signals, or use new sensing reference signals, or reuse communication signals carrying data for sensing, but it is necessary to decode the communication data before sensing processing. Mode (6) is based on sidelink sensing. The potential sensing signal can also be based on the sidelink reference signal, add a new sensing reference signal, or reuse the data signal of the sidelink communication. Considering the widely distributed terminals, mode (3) can shorten the propagation path length of the perception channel by selecting appropriate terminals, thereby improving the perceived signal-to-noise ratio (SNR).
[0152] The supported or unsupported perception modes mentioned above may include the following four:
[0153] (1) The base station transmits and receives independently; (2) Base station A transmits and base station B receives; (3) The base station transmits and the terminal receives; (4) The terminal transmits and the base station receives; 1 bit is used to support or not support the above four types, or 4 bits are used to indicate which sensing modes the cell supports / does not support. For example, bitmap 1010 indicates that the cell supports the first and third sensing modes mentioned above, but does not support the second and fourth sensing modes.
[0154] The sensing modes supported or not supported by the above-mentioned cells may also be specific sensing modes supported or not supported by the cells, such as whether the cell supports the sensing mode of base station self-transmission and self-reception; since the sensing mode of base station self-transmission and self-reception has interference between the transmitted signal and the echo signal of the transmitted signal, the base station is required to have a certain degree of self-interference elimination capability or full-duplex capability, which places higher requirements on the base station; the other three sensing modes do not require the base station to have self-interference elimination capability or full-duplex capability. Therefore, 1 bit can be used to indicate whether the cell supports the sensing mode of base station self-transmission and self-reception. Optionally, the other three base station-related sensing modes are supported by the cell by default.
[0155] The cell supporting or not supporting the sensing service type may include at least one of the following:
[0156] The above cells support or do not support radar detection services, including radar speed measurement, radar ranging, radar angle measurement, and radar imaging;
[0157] Whether the above cells support or do not support user positioning and tracking services;
[0158] The above-mentioned cells support or do not support environmental reconstruction services, including: topography reconstruction, building surface reconstruction;
[0159] The above cells support or do not support weather and / or air quality monitoring services, which may include: rainfall detection, humidity detection, particulate matter detection, and snowfall detection;
[0160] The above cells support or do not support pedestrian / vehicle flow detection services;
[0161] The cells mentioned above may or may not support health monitoring services, which may include: heartbeat monitoring, breathing detection;
[0162] The above cells support or do not support motion recognition services, which may include: gesture recognition, posture recognition, and intrusion detection.
[0163] In some implementations, the aforementioned perception service types may be combined and indicated to save overhead of the first system information.
[0164] The above-mentioned cell support or non-support of the sensing function type may include at least one of the following:
[0165] The above cells support or do not support radar detection, including: radar speed measurement, radar ranging, radar angle measurement, and radar imaging;
[0166] The above cells support or do not support user positioning and tracking;
[0167] The above-mentioned communities support or do not support environmental reconstruction, including: topography reconstruction, building surface reconstruction;
[0168] The cells mentioned above may or may not support weather and / or air quality detection, which may include: rainfall detection, humidity detection, particulate matter detection, and snowfall detection;
[0169] The above cells support or do not support pedestrian / vehicle flow detection;
[0170] The cells mentioned above may or may not support health monitoring, which may include: heartbeat monitoring, breathing detection;
[0171] The above cells support or do not support action recognition, which may include: gesture recognition, posture recognition, and intrusion detection.
[0172] In some implementations, the above-mentioned sensing function types may be combined and indicated to save the overhead of the first system information.
[0173] The sensing waveform supported or not supported by the cell may include at least one of the following:
[0174] Frequency Modulated Continuous Wave (FMCW), Orthogonal frequency division multiplex (OFDM), Single-carrier Frequency-Division Multiple Access (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Frequency Modulated Continuous Wave (FMCW), pulse signals, or other waveforms designed for perception.
[0175] The perception signal supported or not supported by the cell may include at least one of the following:
[0176] 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 designed for perception.
[0177] Since it includes the perception information of the cell, the terminal can determine the perception information of the cell by receiving the first system information. If the perception information of the cell does not match the terminal, the second system information of the cell is not obtained, so as to reduce the energy consumption of the terminal and improve the execution efficiency of cell selection or reselection.
[0178] In an implementation manner, the random access information includes:
[0179] Whether to enable flexible random access opportunity (RACH Occasion, RO).
[0180] Whether to enable the flexible RO may be whether the flexible RO is enabled, or whether to enable or disable the flexible RO.
[0181] Whether to enable flexible RO may indicate whether the terminal enables flexible RO or whether the network side device enables flexible RO.
[0182] In this implementation, since the random access information includes whether to enable flexible RO, the high transmission frequency of the first system information can be utilized to dynamically enable or disable flexible RO through the first system information, thereby improving the flexibility of random access.
[0183] In an embodiment 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 frequently changing information, or may indicate any other information carried in the second system information that needs to be considered in the cell selection and reselection process. In this way, the information is placed in the first system information, allowing the terminal to screen out some candidate cells or determine the priority of the candidate cells, thereby avoiding the terminal reading the second system information of the corresponding cell or the second system information of the low-priority cell, and accelerating the cell selection or reselection process.
[0184] As an implementation manner, when it is determined based on the attribute information of the cell that the cell meets a preset condition, the terminal preferentially selects or reselects the cell; or,
[0185] In a case where it is determined based on the attribute information of the cell that the cell does not meet the preset condition, the terminal preferentially selects or reselects other cells other than the cell.
[0186] Among them, the above-mentioned preset conditions can be protocol agreements, network side configurations or conditions pre-set by the terminal.
[0187] In some embodiments, the aforementioned preset conditions may include at least one of the following:
[0188] The priority of the cell is higher than that of other cells;
[0189] The attribute information of the cell matches the capability of the terminal;
[0190] The attribute information of the cell matches the mobility state of the terminal;
[0191] The attribute information of the cell matches the attribute of the potential service of the terminal.
[0192] The fact that the priority of the cell is higher than that of other cells may mean that the priority of the cell is higher than that of other cells searched by the terminal.
[0193] The attribute information of the above-mentioned cell and the capability matching of the terminal may be that the above-mentioned terminal supports the communication characteristics supported by the cell represented by the attribute information, or it may be that the terminal supports the perception mode, perception service type, perception function type, perception waveform or perception signal, etc. supported by the cell represented by the attribute information, or it may be that the terminal supports the type of cell represented by the attribute information, etc.
[0194] The matching of the attribute information of the above-mentioned cell and the mobility state of the terminal may be that the mobility state of the terminal matches the communication characteristics, perception mode, perception service type or perception function type supported by the cell indicated by the attribute information, or the mobility state of the terminal matches the cell type indicated by the attribute information, for example: the attribute information indicates that the cell is an HSDN cell (or it is 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 mobility, so the two match; for another example: the attribute information indicates that the cell is a non-HSDN cell (or it is 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 mobility, so the two match.
[0195] The attribute information of the above-mentioned cell matches the attributes of the potential service of the terminal, which means that the potential service of the terminal can be transmitted in the cell. For example, the potential service of the terminal includes perception service, and the attribute information indicates that the cell supports perception, so the two match. For another example, the potential service of the terminal includes MBS service, and the attribute information indicates that the cell supports MBS, so the two match.
[0196] The above-mentioned preferential selection or reselection of the cell may be that the terminal preferentially uses the cell as a serving cell or a camped cell, or preferentially obtains the second system information of the cell.
[0197] The above-mentioned priority selection or reselection of other cells outside the cell may be to prioritize other cells outside the cell as serving cells or resident cells, or to prioritize obtaining second system information of other cells outside the cell, and to exclude the cell and not obtain the second system information of the cell.
[0198] The other cells other than the above-mentioned cell may be one or more cells other than the cell.
[0199] In the above-described embodiment, when a cell satisfies the preset conditions, the cell is preferentially selected or reselected. This allows for preferential selection or reselection of cells that satisfy the preset conditions, thereby improving the reliability and efficiency of cell selection or reselection. Furthermore, when a cell does not satisfy the preset conditions, cells other than the cell are preferentially selected or reselected. This reduces the need to read some second system information, thereby improving the efficiency of cell selection or reselection and reducing reception power consumption.
[0200] In some implementations, if the cell meets the aforementioned pre-set conditions, the terminal assigns a high reselection priority to the cell; otherwise, the cell is deemed to have a low reselection priority. For example, if the cell's attributes match the terminal's capabilities / services, etc., the terminal assigns a high reselection priority to the cell; otherwise, the cell is deemed to have a low reselection priority. The cell may be a neighboring cell.
[0201] For cells whose signal quality meets the reselection conditions, the terminal prioritizes reselection from cells with higher priority, reads the second system information of the cell (such as SIB 1), and determines whether it can camp in the cell; if it can camp, the reselection process ends; otherwise, it tries the next cell whose signal quality meets the reselection conditions; and the cycle continues.
[0202] In this way, the terminal can obtain the reselection priority information through the first system information, thereby giving priority to 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). This avoids the situation where, 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. This shortens the duration of the cell reselection process and improves the efficiency of the cell reselection process.
[0203] Optionally, when the terminal preferentially selects or reselects the cell, the terminal preferentially reads the second system information of the cell, and when the cell is determined to be a serving cell or a camped cell based on the second system information, the terminal no longer reads the second system information of other cells; or,
[0204] The terminal preferentially reads the second system information of other cells other than the cell. When determining that the other cell is a serving cell or a camped cell based on the second system information of the other cell, the terminal does not read the second system information of the cell.
[0205] The second system information may be the second system information or other second system information, which is not limited.
[0206] In this embodiment, since the terminal does not read the second system information of other cells when the cell is determined to be the serving cell based on the second system information, terminal resources are saved. Since the terminal does not read the second system information of other cells when the cell is determined to be the serving cell based on the second system information of the other cells, terminal resources are saved.
[0207] Optionally, when the terminal preferentially selects or reselects the cell and reads the second system information of the cell, the second system information includes: indication information indicating that the cell is prohibited from access or prohibited from staying.
[0208] The second system information may be a SIB, such as SIB1.
[0209] The above-mentioned case where the terminal preferentially selects or reselects the cell and the terminal reads the second system information of the cell means: the cell prohibition indication in the above-mentioned first system information is not prohibited, and the cell is determined to meet the preset conditions based on the attribute information of the above-mentioned cell. The terminal preferentially selects or reselects the above-mentioned cell and preferentially reads the second system information of the above-mentioned cell.
[0210] In this implementation, when the first system information indicates no prohibition, the second system information may indicate prohibition of access or prohibition of residency, thereby improving the flexibility of cell access or residency management.
[0211] In some embodiments, the above-mentioned indication information may be an indication to the target terminal that the cell is prohibited from access or prohibited from residence, that is, the above-mentioned indication information indicates that the above-mentioned cell is prohibited from access or prohibited from residence for the target terminal, so that differentiated management of the cell can be achieved, that is, allowing some terminals to access and prohibiting other terminals from accessing or residing, so as to improve the flexibility of cell access or residence management.
[0212] The target terminal may be a terminal specified by the protocol or indicated by the network, or may be referred to as a specific terminal. The target terminal includes but is not limited to at least one of the following:
[0213] RedCap terminal, eRedCap terminal, NTN terminal.
[0214] It should be noted that the above implementation does not limit the above indication information to the target terminal. For example, in some scenarios or situations, there may be no limitation on the terminal to which the above indication information is applied, that is, the indication information is effective for all terminals.
[0215] In some implementations, the second system information further includes a second indication, where the second indication is used to indicate whether intra-frequency cell reselection is allowed within the first frequency.
[0216] The above-mentioned first frequency is the frequency where the above-mentioned cell is located, or the frequency associated with the second system information.
[0217] The second indication may be IFRI.
[0218] In this embodiment, a second indication is introduced in the second system information to indicate whether intra-frequency reselection is allowed. This enables the terminal to perform similar or identical processing on the second indication in the second system information based on the processing method of the first indication of the first system information, thereby reducing the complexity of the terminal.
[0219] The above-mentioned second indication indicating whether intra-frequency cell reselection is allowed within the first frequency may indicate whether a terminal prohibited from accessing or staying by the above-mentioned second system information is allowed to perform intra-frequency reselection within the first frequency, such as indicating whether the above-mentioned target terminal is allowed to perform intra-frequency reselection within the first frequency.
[0220] For example, when the cell barred indication in the first system information is not barred, certain information in the second system information is also used to indicate to the (target) terminal that the cell should be considered barred for the (target) terminal. In this case, in some mechanisms defined in the protocol, after obtaining the second system information, the terminal determines whether intra-frequency reselection is allowed based on the first indication in the first system information. If the first indication in the first system information has already been used for other information indications, then a second indication can be introduced in the second system information to indicate whether the barred terminal is allowed to perform intra-frequency reselection.
[0221] As an implementation manner, when the cell barring indication in the first system information is prohibited, the first indication is used to indicate whether intra-frequency cell reselection is allowed within the first frequency.
[0222] In this implementation, the first indication in the first system information can indicate different contents when the cell barring indication is barred or not barred, so as to indicate more useful information to the terminal through the first system information.
[0223] It should be noted that the various implementations 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 information required for reselection, specifically indicating at least one of the following:
[0224] Whether the current cell supports HSDN;
[0225] Whether the current cell supports emergency calls;
[0226] Whether the current cell supports network slicing;
[0227] Whether the current cell supports MBS, etc.;
[0228] Whether the current cell supports backscatter communication;
[0229] Whether the current cell supports non-terrestrial network communications;
[0230] Whether the current cell supports time and frequency pre-compensation via GNSS;
[0231] Whether the network equipment in the current cell supports linear polarization antennas or circular polarization antennas (left-hand or right-hand polarization);
[0232] Whether the current cell supports multiple frequency bands;
[0233] Whether the current cell supports non-contiguous multi-band;
[0234] Whether the current cell supports multi-level SSB, etc.;
[0235] Whether the current cell is a cell-free cell;
[0236] Whether the current cell supports multiple TRPs.
[0237] This allows the terminal to exclude as many cells that do not meet the reselection conditions as possible before reading the second system information of the candidate cells, thereby accelerating the cell reselection process and improving the cell reselection efficiency.
[0238] In an embodiment of the present application, a terminal receives first system information, where the first system information includes a cell barring indication and a first indication. Wherein, if the cell barring indication indicates non-barring, the first indication is used to indicate at least one of the following: cell attribute information and random access information. This allows the terminal to obtain at least one of the cell attribute information or random access information upon receiving the first system information, thereby improving communication efficiency of the terminal.
