Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a wireless access processing method, apparatus, terminal, and network-side equipment. Background Technology

[0002] With the development of communication technology, in addition to ordinary mobile phone terminals for Enhanced Mobile Broadband (eMBB) services, many low-power wide-area (LPWA) terminal types have emerged in communication systems. These include machine-type communication (MTC) in the Long Term Evolution (LTE) era, narrowband Internet of Things (NB-IoT) and reduced capability (RedCap) and enhanced RedCap (eRedCap) in the New Radio (NR) era.

[0003] Currently, NB-IoT adopts an access system design that is completely independent of ordinary terminals. However, in 5G systems, in order to be compatible with RedCap / eRedCap terminals and ordinary terminals, the system information for terminals with different capabilities adopts a unified system information setting. For example, the system information for ordinary terminals and the system information for RedCap / eRedCap terminals are carried in SIB1. As a result, since the same system information design is adopted, it is impossible to achieve both wide coverage and system efficiency. Summary of the Invention

[0059] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0060] I. LPWA Terminal.

[0061] The deployment of 6G is expected to begin around 2030, and existing cellular IoT devices, such as NB-IoT devices, will also reach the end of their lifespan by then. Therefore, 6G presents an opportune time to deploy a new generation of higher-performance, lower-cost, and larger-scale LPWA devices. With the rollout of 6G, the LPWA market is expected to experience strong growth, penetrating a wide variety of commercially valuable application scenarios (such as logistics management, smart homes, smart cities, etc.).

[0062] Existing 4G LPWA solutions, such as NB-IoT and eMBB, are not well compatible. The physical layers of NB-IoT user equipment and eMBB user equipment differ significantly, increasing both the standardization workload and the cost of NB-IoT user equipment. Furthermore, NB-IoT user equipment requires dedicated NB-IoT base stations, further increasing network deployment costs and operational efficiency. When designing 6G LPWA solutions, we need to address these shortcomings. 6G LPWA and eMBB should be as compatible as possible, especially at the physical layer, where LPWA should reuse eMBB designs as much as possible. Therefore, to reduce the implementation costs of user equipment and base stations, as well as the standardization workload, while 6G Day-1 (Release-20) standardization should focus on eMBB, forward compatibility with LPWA must be fully considered. After the basic functions of eMBB are standardized, LPWA functionality can be implemented through parameter configuration and software modifications, with minimal hardware changes. This will significantly reduce the implementation cost of a single LPWA IoT device, providing a solid foundation for supporting massive connectivity of IoT devices to achieve widespread commercialization of 6G cellular IoT. Correspondingly, on the network side, a single 6G base station will simultaneously serve both LPWA and eMBB devices, dynamically optimizing resource allocation for instantaneous service requests.

[0063] LPWA terminals have at least one of the following limitations compared to normal-capability terminals (eMBB terminals):

[0064] Transmission bandwidth capability;

[0065] Radio frequency (RF) capability;

[0066] Transmission power capability;

[0067] Error detection, demodulation, or decoding capabilities.

[0068] II. Scheduling of NR and NB-IoT System Information Block (SIB) 1.

[0069] In 5G NR, SIB1 scheduling is implemented by the Physical Downlink Control Channel (PDCCH). The relevant configuration parameters for scheduling the PDCCH of SIB1 are given in the master information block (MIB). For 5G NR eMBB terminals, SIB1 reception and scheduling do not consider duplicate transmissions.

[0070] For NB IoT and MTC terminals, the scheduling of TBS and repetition count is performed through MIB, while other time-frequency domain resources are determined by the protocol.

[0071] SIB1-NB and SIB1-MTC contain parameters related to cell access and cell selection, as well as scheduling information for other SIBs.

[0072] The following section uses SIB1-NB as an example to introduce the design related to repeated transmissions. The design of SIB1-MTC is similar to that of SIB1-NB, and will not be described in detail below:

[0073] A SIB1-NB can be transmitted multiple times. The number of repetitions (4, 8, or 16) of the PDSCH carrying the SIB1-NB is obtained through the MIB-NB. This number of repetitions is the number of repetitions within a 2560ms period, and it repeats at equal intervals within this period. Each repetition is transmitted on subframe 4, which occurs every other frame (a total of 8 radio frames) within 16 consecutive frames. The starting system frame for the first transmission of the NPDSCH carrying the SIB1-NB is determined by the repetition count ID and specified by the protocol. Neighboring cells can be configured to have different starting radio frames for their SIB1-NBs, thus ensuring that the SIB1-NBs of different cells are staggered in the time domain and avoiding interference between SIB1-NB transmissions. Since the resource configuration parameters related to the SIB1-NB are fixed: the location, repetition count, and TBS in the time domain are indicated by the MIB-NB and the cell PCI, and in the frequency domain they are located on the anchor carrier and always use QPSK modulation, no control channel (such as NPDCCH) information is needed to indicate how to transmit the SIB1-NB. In other words, when the UE receives the SIB1-NB, it does not need to detect the corresponding NPDCCH. This is different from LTE and NR, where the frequency domain location and transmission format of SIB1 are indicated by the PDCCH scrambled by SI-RNTI.

[0074] III. System Information for 5G NR.

[0075] NR's system information includes Minimum System Information (MSI) and Other System Information (OSI). MSI includes MIB and Remaining Minimum System Information (RMSI), and RMSI includes SIB1.

[0076] Other system information includes system information other than MSI.

[0077] Optionally, the following system information may be included:

[0078] MIB: Includes System Frame Number (SFN), SIB1 scheduling configuration, cell permission information (bar), and intra-frequency cell reselection permission indication;

[0079] SIB1 includes cell selection information, PLMN list, cell identifier, tracking area code, RAN area code, cell reservation indication, scheduling information of system information, configuration related to onboard access, SSB transmission configuration, TDD uplink and downlink configuration, etc.

[0080] SIB2: Includes cell reselection configuration;

[0081] SIB3: Includes information on neighboring cells on the same frequency, including cell reselection parameters;

[0082] SIB4: Includes neighbor cell information on frequencies other than the serving cell frequency and cell information for other radio access technologies, as well as related cell reselection parameters;

[0083] SIB5: Includes LTE carrier frequency and cell information, as well as related cell reselection parameters;

[0084] SIB6 and SIB7: Earthquake-related notification information;

[0085] SIB8: Business Mobility Warning Message;

[0086] SIB9: Wireless system clock information, based on Coordinated Universal Time (UTC) time indication.

[0087] In addition, there are other system information introduced for different purposes, including SIB10 to SIB25.

[0088] IV. Sending system information.

[0089] System information is broadcast. Before accessing a cell, a terminal needs to receive at least some system information, including the MIB and SIB1, to determine the system parameters related to random access, including random access resources and uplink / downlink initial bandwidth part configuration. The MIB and SIB1 of a cell are continuously broadcast, while other system information (OSI) can be broadcast continuously or sent on demand.

[0090] SIB1 contains scheduling information (SI_SchedulingInformation) related to the transmission of other system information. This information is used to configure parameters for the terminal to receive other system information, including the transmission period, group configuration, indication of whether broadcast transmission is in progress, transmission window length, and on-demand transmission configuration for each system information (SIB) in the other system information.

[0091] The terminal receives other system information by sending relevant scheduling information based on other system information. If the terminal determines that it wants a system information that is in the scheduling information list but not broadcast, it can send a system information request to the base station according to the system information request configuration provided in the scheduling information. According to the NR protocol definition, the terminal can request the base station to send system information through the Physical Random Access Channel (PRACH) (Msg1) resource dedicated to system information requests or information 3 (Msg3) in the random access procedure. When the terminal sends a system information request via PRACH, the base station sends a response signal RAR to the terminal after receiving the request, informing the terminal that the system information request has been received; when the terminal sends a system information request to the base station via Msg3, the base station sends information 4 to the terminal to reply to the terminal. After the terminal successfully sends a system information request, it monitors and receives the system information sent by the base station. To conserve system resources, NR can configure the terminal to indicate that it wants one or more system information messages from other system messages via PRACH or Msg3, and the base station sends the one or more system information messages that the terminal wants according to the terminal's request.

[0092] V. System Information Reading and Retention.

[0093] The Radio Resource Control (RRC) protocol stipulates that when a terminal cannot acquire the MIB or SIB1, the terminal will treat the cell as barred, and the terminal will perform cell reselection behavior according to the relevant parameters after being barred.

[0094] If the terminal can obtain the MIB and read the SIB1, it can obtain the serving cell public configuration information and PDCCH configuration information, thereby enabling it to listen for system messages and paging, and achieve a camping state.

[0095] It should be noted that currently, NB-IoT adopts a completely independent access system design compared to ordinary terminals, with its access bandwidth and related signals designed independently. While 5G systems are designed to be compatible with RedCap / eRedCap terminals and ordinary terminals to some extent, they inevitably cannot balance wide coverage and system efficiency due to the use of the same system messages. Furthermore, 5G systems are not compatible with NB-IoT, requiring NB-IoT to be deployed separately.

[0096] In 6G systems, it is considered that eMBB ordinary terminals, RedCap / eRedCap terminals, and ordinary terminals should access the same network using a unified Radio Access Technology (RAT). Therefore, the design must take into account the different coverage requirements introduced by the differences in terminal capabilities, while also considering system efficiency and terminal power saving. To this end, the radio access processing method proposed in this application is proposed.

[0097] The wireless access processing method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0098] Reference Figure 2 This application provides a wireless access processing method, such as... Figure 2 As shown, the wireless access processing method includes:

[0099] Step 201: The terminal receives first information from the first cell, the first information including a first transport block, or including a first transport block and a second transport block;

[0100] Wherein, the first transmission block includes first system information, and the second transmission block includes second system information; the first system information is used for terminals that meet the first condition, or the first system information is used for terminals that meet the first condition and terminals that meet the second condition, and the second system information is only used for terminals that meet the second condition;

[0101] The first condition includes at least one of the following: supporting the first service but not supporting the second service; the terminal is in the first state or has changed to the first state; the terminal's capability level is the first level or has changed to the first level.

[0102] The second condition includes at least one of the following: supporting the second service, the terminal being in the second state or changing to the second state; the terminal's capability level being the second level or changing to the second level;

[0103] Wherein, the first state is different from the second state, and the terminal being in the first state includes at least one of the following: the wireless channel conditions of the terminal are in a first coverage range state; the terminal only supports small data packet services; the terminal is in a radio resource control (RRC) non-connected state; the terminal is running in a network power saving mode; the terminal battery level is lower than or equal to a first threshold; the terminal is running in a low power mode.

[0104] In this embodiment, the number of the first and second transmission blocks can be one or more. In some embodiments, the first or second transmission block can be understood as a system information block corresponding to a certain service, transmission module, function combination, receiving bandwidth, power level, or coverage level. The first or second system information can be understood as system information of one or more system types.

[0105] Optionally, the terminal changing to the first state can be understood as: the terminal changing from the second state to the first state; alternatively, the terminal changing to the second state can be understood as: the terminal changing from the first state to the second state.

[0106] Optionally, in some embodiments, the first transport block and the second transport block are system information blocks. That is, the first information can be understood as a system information block, such as SIB1, wherein the first system information can be understood as a part of the first information, and the second system information can be understood as another part of the first information, that is, the first system information can be understood as a part of SIB1, and the second system information can be understood as another part of SIB1.

[0107] Optionally, in some embodiments, the first information can be understood as two system information blocks, for example, the first system information includes SIB1 and the second system information includes SIBX.

[0108] It should be noted that "the first system information used by terminals satisfying the first condition" can be understood as meaning that terminals satisfying the first condition can apply the first system information. For example, after receiving the first system information, a terminal satisfying the first condition can use the first system information for camping or random access. "The first system information used by terminals satisfying the first condition and terminals satisfying the second condition" can be understood as meaning that both terminals satisfying the first condition and terminals satisfying the second condition can use the first system information for camping or random access after receiving it. "The second system information used only by terminals satisfying the second condition" can be understood as meaning that the second system information can only be used by terminals satisfying the second condition, or in other words, only terminals satisfying the second condition receive and demodulate the second system information and can use the second system information to perform related operations. Terminals satisfying the first condition do not receive or demodulate the second system information.

[0109] Optionally, in this embodiment, the system information content required by the terminal that meets the first condition is placed in the first transmission block, while the terminal-specific or incremental content that meets the second condition is placed in the second transmission block. For example, in some embodiments, the first system information is the parameter configuration required by the first service, and the second system information is the parameter configuration required by the second service; or the first system information is the parameter configuration required by both the first and second services, which can also be called common parameter configuration, and the second system information is the remaining parameter configuration required by the second service, which can also be called dedicated parameter configuration. Of course, in some embodiments, the reverse is also feasible. For example, the system information content required by the terminal that meets the second condition is placed in the first transmission block, while the terminal-specific content that meets the first condition is placed in the second transmission block.

[0110] Optionally, in some embodiments, the first service described above can be a Low Power Wide Area Network (LPWA) access service, and the second service can be an Enhanced Mobile Broadband (eMBB) access service. A terminal satisfying the first condition can be understood as a first type of terminal, for example, an LPWA terminal; a terminal satisfying the second condition can be understood as a second type of terminal, for example, an eMBB terminal, or a regular terminal.

[0111] It should be noted that the aforementioned low-power mode can also be called a power-saving mode. In some embodiments, the terminal's battery level can be used as a criterion for determining whether the terminal is operating in low-power mode. For example, when the terminal's battery level is lower than or equal to a first threshold, the terminal can enter low-power mode.

[0112] It should be noted that the aforementioned capability levels can also be referred to as capability categories or capability profiles. In some embodiments, the capability level of a terminal may correspond to at least one capability parameter.

[0113] Optionally, if the terminal is in the first state, it can be considered as a terminal with reduced capabilities or an LPWA terminal; if the terminal changes to the first state, it can be considered as a terminal with reduced capabilities.

[0114] Optionally, being in the first coverage area state can be understood or replaced as being in the deep coverage state, also known as being in the maximum coverage extension level (MCE). Deep coverage extension refers to maximizing signal strength and capacity within the coverage area by increasing base station density or adjusting base station transmit power in a wireless communication network. For example, when the terminal's Reference Signal Receiving Power (RSRP) is lower than or equal to the RSRP threshold, the terminal is in the deep coverage state.

[0115] Optionally, in some embodiments, the first level is different from the second level, and the capability level of the terminal is determined based on at least one of the following: bandwidth information supported by the terminal, peak data rate information supported by the terminal, bandwidth information of the terminal operation, coverage information, power consumption information, energy saving information, terminal type information, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, decoding capability, and duplex mode.

[0116] It should be understood that in some embodiments, the capability level of the terminal may remain constant, i.e., the capability level of the terminal is always at level one or level two. In some embodiments, the capability level of the terminal may support dynamic changes, for example, it may be changed to level two or level one.

[0117] It should be noted that the terminal's capability level can include two or more capability levels. Changing the terminal's capability level to level one can be understood as changing the terminal's capability level from level two to level one, or from any other level to level one. Similarly, changing the terminal's capability level to level two can be understood as changing the terminal's capability level from level one to level two, or from any other level to level two.

[0118] In this embodiment, a terminal receives first information from a first cell. This first information includes a first transmission block, or a first transmission block and a second transmission block. The first transmission block includes first system information, and the second transmission block includes second system information. The first system information is used by a terminal that meets a first condition, or by a terminal that meets the first condition and a terminal that meets a second condition. The second system information is only used by a terminal that meets the second condition. The first condition includes at least one of the following: supporting a first service but not supporting a second service; the terminal is in a first state or has changed to a first state; the terminal's capability level is a first level or has changed to a first level. The second condition includes at least one of the following: supporting a second service; the terminal is in a second state or has changed to a second state; the terminal's capability level is a second level or has changed to a second level. The first state is different from the second state, and the terminal being in the first state includes at least one of the following: the terminal's radio channel condition is in a first coverage state; the terminal only supports small data packet services; the terminal is in a Radio Resource Control (RRC) non-connected state; the terminal is running in a network power-saving mode; the terminal's battery level is lower than or equal to a first threshold; the terminal is running in a low-power mode. In this way, by using different transport blocks to transmit system information for different terminals, it is possible to design independently for different system information to meet the coverage requirements of different terminals and improve system efficiency.

[0119] Optionally, in some embodiments, when the terminal satisfies the first condition, the method includes:

[0120] The terminal uses the information from the first system.

[0121] In this embodiment of the application, when a terminal that meets the first condition receives the first system information, the terminal can apply the first system information.

[0122] Optionally, in some embodiments, if the terminal satisfies the second condition, the method further includes at least one of the following:

[0123] When the terminal receives the first transmission block, the terminal applies the first system information;

[0124] When the terminal receives the second transport block, the terminal applies third system information, wherein the third system information is the second system information, or the third system information is determined based on the first system information and the second system information.

[0125] In this embodiment, when the terminal receives the first transport block, it can directly apply the first system information to achieve basic camping, enabling the first cell to provide the terminal with the first service; if the second transport block is subsequently received, it can apply the third system information to achieve enhanced camping, enabling the first cell to provide the terminal with the first service and the second service.

[0126] Optionally, in some embodiments, the first system information is a common set of system information for terminals that satisfy the first condition and terminals that satisfy the second condition, and the second system information is dedicated system information for terminals that satisfy the first condition.

[0127] In this embodiment, the first system information, which is a common set of system information for terminals satisfying the first condition and terminals satisfying the second condition, can be understood as: the first system information is common configuration information, or in other words, the first system information is common configuration information for the first service and the second service; the second system information, which is dedicated system information for terminals satisfying the second condition, can be understood as: the second system information is dedicated configuration information, or in other words, the second system information is dedicated configuration information for the second service. The common system information set can also be called the necessary system information set, that is, the minimum system set required to achieve residency or access.

[0128] Optionally, in some embodiments, after the terminal applies the first system information, the method further includes:

[0129] The terminal performs at least one of the following:

[0130] Read system information other than the first system information;

[0131] Read public information;

[0132] Read paging messages;

[0133] Initiate a random access procedure.

[0134] In this embodiment of the application, after reading the paging message, information about the called party or group call can be obtained from the paging message. The paging message monitoring can be performed on the same carrier, control resource set (Coreset), or search space as reading other system information and public information besides the first system information. Alternatively, different carriers, Coresets, or search spaces can be obtained from the basic information, which differ from the system information and public information, for paging monitoring.

[0135] Optionally, the terminal can obtain random access-related configuration information from the first system message. The configuration information may be located in the same carrier, Coreset (Control resource set), or SearchSpace as other system information and public information besides the first system information, or it may be different.

[0136] Optionally, in some embodiments, the third system information includes at least one of the following:

[0137] The first parameter has a first value, wherein the first system information includes the first parameter, the second system information does not include the first parameter, and the first value is the parameter value corresponding to the first parameter in the first system information.

[0138] The second parameter has a second value, wherein the second system information includes the second parameter and the second value is the parameter value corresponding to the second parameter in the second system information;

[0139] The third parameter is determined based on a third value and a fourth value, wherein the first system information includes the third parameter, the second system information includes the third parameter, the third value is the parameter value corresponding to the third parameter in the first system information, and the fourth value is the parameter value corresponding to the third parameter in the second system information;

[0140] The fourth parameter is determined based on the fifth and sixth values. The first parameter configuration includes the fourth parameter, the second parameter configuration includes the fifth parameter, the fifth parameter is associated with the fourth parameter, the fourth value is the parameter value corresponding to the fourth parameter in the first parameter configuration, and the fifth value is the parameter value corresponding to the fifth parameter in the second parameter configuration.

[0141] In some embodiments, the first parameter is included in the first system information but not in the second system information. In this case, the parameter value corresponding to the first parameter in the first system information can be directly determined as the parameter value of the first parameter in the third system information. This eliminates the need for additional configuration of the first parameter through the second system information, thereby reducing signaling overhead.

[0142] In some embodiments, when the second system information includes a second parameter, the second parameter can be used as a parameter in the third system information. In this case, regardless of whether the first system information includes a second parameter, the second parameter included in the first system information can be ignored.

[0143] In some embodiments, when the third parameter is included in both the first system information and the second system information, the third parameter of the third system information can be determined jointly by combining the first system information and the second system information. For example, if the third parameter in the first system information is used to configure the lower n bits of the sequence value, and the third parameter in the second system information configures the higher m bits of the sequence value, then the third parameter in the third system information is an m+n bit sequence value.

[0144] In some embodiments, the fifth parameter in the second system information can be understood as an incremental configuration for the fourth parameter. For example, the fifth parameter can be an offset value, and the parameter value corresponding to the fourth parameter in the third system information is the value corresponding to the fourth parameter in the first system information plus the offset value corresponding to the fifth parameter.

[0145] Optionally, the method further includes:

[0146] The terminal receives a Master Information Block (MIB), which includes the scheduling information of the first transport block.

[0147] In this embodiment, the aforementioned scheduling information can be referred to as scheduling and control information. Because the scheduling information of the first transport block is included in the MIB, the terminal can quickly and accurately obtain the first transport block through the MIB, thereby completing the dwell.

[0148] Optionally, in some embodiments, the scheduling information of the second transport block is included in the MIB or in the first transport block.

[0149] Optionally, the scheduling information for the second transport block can be indicated explicitly or implicitly.

[0150] For explicit scheduling, there is a dedicated field for scheduling information of the second transport block.

[0151] For implicit scheduling, there is a field for scheduling the first transport block, but the first transport block and the second transport block can have a certain relationship, such as the second transport block being in the next time slot of the second transport block; or, there is a field from which the terminal can look up the table to obtain the scheduling of the first transport block and the second transport block at the same time.

[0152] The design of this table is illustrated below: For example, 4 bits, 16 code points, where:

[0153] 1. First transport block scheduling configuration 1;

[0154] 2. First transport block scheduling configuration 2;

[0155] 3-8, First transmission block scheduling configuration 3-8;

[0156] 9-16, Scheduling configuration combinations 1-8 for the first and second transport blocks.

[0157] Optionally, in some embodiments, the first transport block and the second transport block are scheduled and identified by different System Information Radio Network Temporary Identifiers (SI-RNTI).

[0158] In this embodiment, the first transport block and the second transport block are scheduled using different SI-RNTI identifiers. This allows a terminal that meets the first condition to receive and demodulate only the first transport block without needing to demodulate the second transport block, thus reducing the terminal's power consumption. Of course, in some embodiments, the first transport block and the second transport block can be scheduled using the same SI-RNTI identifier, which reduces the complexity of terminal detection.

[0159] Optionally, in some embodiments, the method further includes at least one of the following:

[0160] If the first condition is met and the terminal does not receive the first transmission block, the terminal determines that the first cell is blocked.

[0161] If the second and third conditions are met, the terminal determines that the first cell is blocked;

[0162] The third condition includes at least one of the following:

[0163] If the terminal supports cell camping based on the first system information but does not support cell camping based on both the first system information and the second system information, the terminal does not receive the first transmission block.

[0164] If the terminal does not support cell camping based on the first system information, but supports cell camping based on both the first system information and the second system information, the terminal does not receive the second transmission block.

[0165] If the terminal supports cell camping based on the first system information and the second system information, the terminal does not receive at least one of the first transport block and the second transport block.

[0166] In this embodiment of the application, when the terminal determines that the first cell is blocked, the terminal needs to perform cell reselection under the control of network parameters to find a suitable cell.

[0167] Optionally, for a terminal that meets the first condition, if the terminal cannot receive the first transmission block, the terminal cannot obtain the first system information, resulting in the inability to complete camping, thereby determining that the first cell is blocked.

[0168] Optionally, for a terminal that meets the second condition, if the terminal supports cell camping based on the first system information but does not support cell camping based on both the first system information and the second system information, the terminal can camp based on the first system information in the first transmission block after receiving the first transmission block. Therefore, if the terminal does not receive the first transmission block, it cannot complete the camping, thereby determining that the first cell is blocked.

[0169] Optionally, for a terminal that meets the second condition, if the terminal does not support cell camping based on the first system information but supports cell camping based on both the first system information and the second system information, then if the first transport block is not received, the terminal can directly camp based on the second system information in the second transport block if the second transport block is received. Therefore, if the second transport block is not received, camping cannot be completed, thus it can be determined that the first cell is blocked.

[0170] Optionally, for terminals that meet the second condition, if the terminal supports cell camping based on the first system information and the second system information, the terminal needs to determine the third system information based on the first and second system information, and then camp based on the third system information. Therefore, if at least one of the first and second transport blocks is not received, the third system information cannot be determined, resulting in the inability to complete camping, thereby confirming that the first cell is blocked.

[0171] Optionally, in some embodiments, the method further includes:

[0172] When the terminal receives the first transport block, the terminal sends a request message to the network-side device, the request message being used to request the acquisition of the second transport block.

[0173] In this embodiment, the second transport block can be a transport block sent on demand. That is, when the network-side device receives a request from the terminal to obtain the second transport block, the network-side device can send the second transport block; otherwise, the network-side device only sends the first transport block. By adopting an on-demand sending method, the invalid sending of the second transport block by the network-side device can be reduced, thereby saving the power consumption of the network-side device. At the same time, the terminal does not need to receive and decode invalid second transport blocks, thereby reducing the terminal's power consumption.

[0174] Optionally, in some embodiments, the transmission of the second transport block may be triggered by a terminal's on-demand request, as stipulated by a protocol or instructed by the network device. Furthermore, the first transport block may carry second information. After receiving the second information, the terminal can send a request message based on it. The second information can be a switch or information that triggers the on-demand transmission of the second transport block. When a terminal meeting the second condition approaches the first cell or when a terminal meeting the second condition has a relevant service requirement, the terminal requests the network-side device to broadcast the second transport block for higher-level operations; otherwise, the terminal can only perform basic operations based on the first system information of the first transport block.

[0175] Optionally, in some embodiments, the terminal application system information method satisfies at least one of the following:

[0176] After all terminals receive the first transport block, they apply the first system information; after terminals that meet the second condition receive the second transport block, they apply the third system information.

[0177] After receiving the first transport block, the terminal that meets the first condition applies the first system information; after receiving the first transport block and the second transport block, the terminal that meets the second condition applies the third system information.

[0178] The method of terminal application system information that satisfies the second condition is determined based on the first indication information sent by the network side device. The first indication information is used to indicate whether to apply the third system information after receiving the first and second transport blocks.

[0179] The method of obtaining terminal application system information that satisfies the second condition is determined based on the second indication information sent by the network-side device. The second indication information is used to indicate whether to transmit the first transport block and not transmit the second transport block, or to indicate whether the second transport block exists.

[0180] In this embodiment, for a terminal that meets the second condition, the first system information can be directly applied after receiving the first transport block. In this case, the actions performed by the terminal meeting the second condition based on the first system information are consistent with the actions performed by the terminal meeting the first condition based on the first system information; these actions can be referred to as basic operations. Further, after receiving the second transport block, related actions are performed based on the third system information; these actions can be referred to as higher-order operations. Alternatively, the related actions can be performed based on the third system information only after receiving both the first and second transport blocks.

[0181] Optionally, the aforementioned first indication information can be understood as the network-side device being able to explicitly indicate whether a terminal that meets the second condition should remain stationary after receiving the first transport block, or after receiving both the first and second transport blocks.

[0182] Optionally, the aforementioned second indication information can be understood as the network-side device being able to explicitly or implicitly indicate whether a terminal that meets the second condition should only receive the first transport block for residing.

[0183] Optionally, the first indication information is included in the main information block or the first transport block; or, the second indication information is included in the main information block, the first transport block, or the downlink control information (DCI).

[0184] Optionally, in some embodiments, the method further includes:

[0185] The terminal receives third indication information from the network-side device, the third indication information being used to indicate at least one of the following:

[0186] Whether to distinguish between the first service and the second service;

[0187] Whether to distinguish between the first state and the second state;

[0188] Whether to distinguish between the first level and the second level.

[0189] In this embodiment, the aforementioned third indication information can be understood as indicating whether the first cell supports the second transport block, or indicating whether it supports new features of the second transport block. Specifically, the third indication information can be explicit or implicit. For example, it can indicate support for the second transport block with one bit, i.e., support for distinguishing between the first service and the second service, support for distinguishing between the first state and the second state, or support for distinguishing between the first level and the second level. It can also be implicitly indicated, for example, by whether the scheduling information field of the second transport block appears in the MIB or the first transport block, indicating whether the second transport block is supported. If the scheduling information field of the second transport block appears, it indicates support for the second transport block; otherwise, it indicates no support. This allows the system to fall back to the operation of a single transport block.

[0190] Optionally, in order to better understand this application, the following explanation will take SIB1 as the first information, LPWA terminal as the terminal that meets the first condition, and ordinary terminal (i.e. eMBB terminal) as the terminal that meets the second condition.

[0191] In some embodiments, to meet the shared access requirements of LPWA terminals and normal terminals, from the perspective of system and terminal efficiency, the SIB1 of the unified access system can be considered to transmit in two transport blocks (TBs). Access methods may include the following:

[0192] Method 1: All terminals can reside in the network after receiving TB1 (i.e., the first transmission block). Furthermore, normal 6G terminals can be further enhanced if they receive TB2.

[0193] Method 2: LPWA terminals can run on the network after receiving TB1, while normal 6G terminals need to receive both TB1 and TB2 to run on the network.

[0194] Method 3: Explicitly indicate via the first indication information (in MIB or SIB1) whether normal 6G can reside on TB1 or only reside on TB2 after receiving TB1.

[0195] Method 4: Explicitly or implicitly indicate via the second indication information (in MIB or SIB1) whether normal 6G only receives TB1 for dwell or whether TB2 appears.

[0196] In this embodiment, SIB1 is used as an example. A similar approach can be applied to the configuration of other system information blocks or public information. The main difference is that SIB1 contains the most basic configuration information of the serving cell. Only by correctly obtaining the content in the corresponding SIB1 can the cell be camped and subsequent data operations performed. For other system information blocks or public information, multiple configuration levels facilitate the breakdown of functions and parameters, allowing different types of terminals to obtain corresponding function and parameter support. If not all information is available, the function cannot be enabled.

[0197] Optionally, regarding Method 1: Since LPWA terminals represent a lower-capability terminal type, while ordinary terminals generally have higher capabilities and service transmission requirements, in order for both LPWA and eMBB users to obtain the key information in SIB1, the necessary system information configurations required by LPWA and eMBB can be configured into a minimum set to form the first transport block in SIB1. Meanwhile, the higher-capability and better service assurance configurations dedicated to eMBB terminals in SIB1 can be formed into the second transport block of SIB1.

[0198] The first transport block in SIB1 is the foundational step for all access, so its scheduling and control information can be included in the MIB. This allows the terminal to quickly and accurately obtain the first transport block in SIB1 through the MIB, thereby completing the camping process.

[0199] Since the second transport block in SIB1 is supplementary information or special information specific to eMBB, its scheduling information can be obtained by associating it with the scheduling method of the first transport block or the SIB1 scheduling information in the MIB in a predetermined way, such as a fixed offset. Alternatively, the scheduling information of the second transport block can be carried by the first transport block, which is more flexible. After obtaining the first transport block, the terminal decides whether to obtain the second transport block according to its own type and / or service requirements.

[0200] Generally, the first transport block in SIB1, due to its higher coverage requirements (e.g., LPWA terminals with only one receiving antenna or low capability), may require more repetitions to ensure a higher reception success rate. Below are some examples of time-domain retransmissions. In these methods of distinguishing the first and second transport blocks in the time domain, since the two transport blocks may be located in different time slots or time domain positions, the same SI-RNTI can be used for scheduling identification. The initial scheduling indication information indicates which transport block a given time slot or time domain position belongs to. Optionally, the transport block's internal message field or message type can also explicitly indicate which transport block it is.

[0201] In addition, the first and second transport blocks of SIB1 can also be separated in the frequency domain. For example, the first and second transport blocks can be scheduled using the same or different SI-RNTIs. LPWA terminals or ordinary eMBB terminals can read only the scheduling and content of the first transport block, while ordinary eMBB terminals can further read the scheduling and content of the second transport block as needed.

[0202] The first transport block of SIB1 may contain at least one of the following:

[0203] Cell selection information, including cell selection thresholds, offsets and other related parameters, is used for basic cell selection and also considers cell selection and camping for LPWA and eMBB terminals.

[0204] Information related to cell access may include a list of PLMN (Public Land Mobile Network) identifiers and SNPN (Stand-alone Non-Public Network) access parameters;

[0205] Connection establishment failure control information, which may include failure counters, failure offsets, failure offset validity parameters, etc.

[0206] The scheduling information of other system message blocks, SIB1 generally contains the scheduling information of other SIBs, such as SIB2-SIB25. However, since the first transport block contains necessary common information, the LPWA terminal may not support other features and may only need to contain the scheduling information of some system information blocks, such as SIB2-5.

[0207] The common configuration of the serving cell is an important configuration domain, which includes the necessary common configurations for a terminal to perform uplink and downlink transmissions within the cell, such as SUL (Supplementary Uplink) configuration, SSB configuration, TDD uplink and downlink configuration, channel access mode, discovery burst window configuration, high-speed configuration, enhanced measurement configuration, and random access channel configuration.

[0208] The values ​​of the terminal timer and constant parameters are mainly used for assigning values ​​to some commonly used timer lengths and constant parameters;

[0209] User Access Control (UAC) Barring configuration can include access control and barring related parameters;

[0210] Measurement-related parameters can include enhanced measurement characteristic parameters;

[0211] Features include support for emergency calls, call over IMS, high-speed dedicated network (HSDN), small data transmission (SDT), RedCap / eRedCap, enhanced discontinuous reception (eDRX), integrated access and backhaul (IAB), and mobile IAB.

[0212] Generally, whether it's an LPWA terminal or a regular eMBB terminal, after reading the first transport block of SIB1, it can camp on the current serving cell, meaning it can perform at least one of the following operations:

[0213] Read system information and public information;

[0214] Reading paging messages allows you to obtain information about your called parties or group calls. Listening to paging messages can be done on the same carrier, coreset (control resource set), or search space as reading system information and public information. Alternatively, you can obtain different carriers, coresets, or search spaces than system information and public information for paging listening.

[0215] To initiate a random access procedure, the relevant random access configuration can be obtained from the SIB1 message. The configuration information can be located on the same carrier, Coreset (Control resource set), or SearchSpace as the system information and public information, or they can be different.

[0216] If an LPWA terminal or a regular eMBB terminal cannot obtain the first SIB1 transport block from the cell, it is equivalent to the cell being in a barred state for the terminal. The terminal cannot complete normal camping behavior and needs to perform cell reselection under the control of network parameters to find a suitable cell again.

[0217] In addition to the first transport block of SIB1, the serving cell may also broadcast the second transport block of SIB1. The content of the second transport block may include at least one of the following:

[0218] Cell selection related information, including cell selection thresholds, offsets and other related parameters, is used for basic cell selection, and is also considered for cell selection and camping of LPWA and eMBB terminals. This information can cover the corresponding content in the first transport block, or be added as a supplement to the first transport block, or be used in combination with the first transport block, specifically for high-order cell selection or cell selection parameters specific to eMBB terminals.

[0219] Cell access related information may include a PLMN (Public Land Mobile Network) identifier list, SNPN (Stand-alone Non-Public Network) access parameters, etc. Similarly, this information may also cover the corresponding content in the first transport block, or be added as a supplement to the first transport block, or be used in combination with the first transport block, specifically for high-order cell access or cell access parameters specific to eMBB terminals.

[0220] Connection establishment failure control information may include a failure counter, failure offset, failure offset validity parameters, etc. This information may also cover the corresponding content in the first transport block, or be an added field as a supplement to the first transport block, or be used in combination with the first transport block, specifically for higher-order connection establishment failure control or connection establishment failure control parameters specific to the eMBB terminal.

[0221] The scheduling information for other system message blocks, SIB1 generally includes the scheduling information for other SIBs, such as SIB2-SIB25. However, since the first transport block contains necessary common information, the LPWA terminal may not support other features and may only need to include the scheduling information for some of the system information blocks, such as SIB2-5. This information can also cover the corresponding content in the first transport block, or be added as a supplement to the first transport block, or be used in combination with the first transport block for higher-order system information block scheduling or system information block scheduling parameters specific to the eMBB terminal. For example, it can contain any number of required system information block scheduling parameters from SIB 6-25.

[0222] The common configuration of the serving cell is an important configuration field, which includes the necessary common configurations for a terminal to perform uplink and downlink transmissions within the cell, such as SUL (Supplementary Uplink) configuration, SSB configuration, TDD uplink and downlink configuration, channel access mode, discovery burst window configuration, high-speed configuration, enhanced measurement configuration, and random access channel configuration. This information can also cover the corresponding content in the first transport block, or be added as a supplement to the first transport block, or be used in combination with the first transport block, specifically for higher-order serving cell operating parameters or serving cell operating parameters specific to eMBB terminals.

[0223] The values ​​of terminal timers and constant parameters are mainly used for assigning values ​​to some commonly used timer lengths and constant parameters; this information can also cover the corresponding content in the first transport block, or be added as a supplement to the first transport block, or be used in combination with the first transport block, specifically for assigning higher-order lengths and constants or for assigning lengths and constants specific to eMBB terminals;

[0224] UAC Barring configuration may include access control and denial-related parameters; this information may also override the corresponding content in the first transport block, or be an added field as a supplement to the first transport block, or be used in conjunction with the first transport block, specifically for higher-order access and denial control or for access and denial control specific to eMBB terminals.

[0225] Measurement-related information may include enhanced measurement characteristic parameters; this information may also cover the corresponding content in the first transport block, or be an added field as a supplement to the first transport block, or be used in conjunction with the first transport block for high-order measurement control or measurement control specific to the eMBB terminal.

[0226] Features include whether emergency calls are supported, whether Call over IMS is supported, whether HSDN (High Speed ​​Dedicated Network), SDT (Small Data Transmission), RedCap (Reduced Capability) / eRedCap, eDRX (Enhanced Discontinuous Reception), IAB (Integrated Access and Backhaul), mobile IAB, etc. This information can also cover the corresponding content in the first transport block, or be added as a supplement to the first transport block, or be used in combination with the first transport block, specifically for high-level feature support or feature support specific to eMBB terminals.

[0227] When a terminal is in a serving cell that simultaneously broadcasts the first and second transport blocks of SIB1, the terminal's behavior may include at least one of the following:

[0228] If it is an LPWA terminal, after obtaining the SSB and synchronization through the initial cell search, it obtains the MIB information, obtains the scheduling of the first transport block of SIB1 from the MIB information, and then receives the first transport block. After successfully obtaining the first transport block of SIB1, it can complete the camping of the serving cell, including listening to system messages and public information, listening to paging, initiating random access, etc., and then wait for its uplink and downlink service needs and communicate normally with the serving cell. Since the LPWA terminal does not have high-level capabilities, it usually does not need to read the second transport block of SIB1.

[0229] If it is a regular eMBB terminal, after obtaining the SSB and synchronization through the initial cell search, it obtains the MIB information, obtains the scheduling of the first transport block of SIB1 from the MIB information, and then receives the first transport block. After successfully obtaining the first transport block of SIB1, it can complete the basic camping in the serving cell. It is called basic camping because at this time, although the eMBB terminal can perform at least one of the following behaviors, including listening to system messages and public information, listening to paging, and initiating random access, it may not be able to initiate some high-requirement services, such as some high-bandwidth, high-speed, or high-quality-of-service services, due to the limited initial bandwidth and configuration of the system.

[0230] If it is a regular eMBB terminal, after it has obtained the first transport block of SIB1 and is in the basic camping state, depending on user preferences or service needs, it can further obtain the second transport block of SIB1 to obtain higher-level or more eMBB-specific service parameters and cell configuration parameters. This is equivalent to it entering a higher-level camping state. In the higher-level camping state, the terminal listens for more and richer system messages and public messages, and may have different or the same paging listening and random access parameters than in the basic camping state. For example, in the higher-level camping state, because it supports more information configuration in SIB1, it can obtain additional SIBs and new feature support, larger bandwidth random access resource configuration, more frequent paging listening, etc. The eMBB terminal can obtain better service and quickly initiate services with high bandwidth, high speed, and high service quality requirements.

[0231] If it is a regular eMBB terminal, after it has acquired the first and second transport blocks of SIB1, it is originally in a high-order dwell state. However, due to factors such as the end of the service, low battery power, or current coverage problems, it can also fall back to the basic dwell state, that is, only listen to less system information and public information, possibly with a longer paging period and less bandwidth random access resources.

[0232] It should be noted that since the second transport block of SIB1 is upgrade information and not basic information, it can also be sent on-demand, i.e., triggered on demand. The switch or information for triggering the on-demand transmission of the second transport block is carried in the first transport block of SIB1. When an eMBB terminal approaches the cell or has a relevant service requirement, it requests the broadcast transmission of the second transport block of SIB1 from the network for higher-level operations.

[0233] For Method 2: Similar to Method 1, in Method 2, since LPWA terminals represent a lower-capability terminal type, ordinary eMBB terminals generally have higher capabilities and service transmission requirements. To ensure that both LPWA and eMBB users can obtain the key information in SIB1, the necessary system information configurations required by LPWA and eMBB can be configured into a minimal set to form the first transport block of SIB1. Meanwhile, the configurations in SIB1 dedicated to the higher capabilities and better service guarantees for eMBB terminals can form the second transport block of SIB1.

[0234] The scheduling and transmission methods for the first and second transport blocks of SIB1 are similar to those in Method 1, and their content can also be similar. However, the difference lies in the content of the first transport block. The content of the first transport block is only sufficient for normal communication by the LPWA terminal, essentially serving as the LPWA terminal's configuration set. For ordinary eMBB users, the content of the first transport block is insufficient for normal communication. Therefore, for the network, the second transport block carries configuration information from the eMBB terminal that differs from that of the LPWA terminal, and / or additional configuration information added by the eMBB terminal. For the eMBB terminal, it must simultaneously read both the first and second transport blocks of SIB1 to complete normal residency.

[0235] In other words, an LPWA terminal can camp on the current serving cell after reading the first transport block of SIB1, while a regular eMBB terminal can only camp on the current serving cell after successfully acquiring both the first and second transport blocks of SIB1. Camping means being able to perform at least one of the following operations:

[0236] Read system information and public information;

[0237] Reading paging messages allows you to obtain information about your called parties or group calls. Listening to paging messages can be done on the same carrier, coreset (control resource set), or search space as reading system information and public information. Alternatively, you can obtain different carriers, coresets, or search spaces than system information and public information for paging listening.

[0238] To initiate a random access procedure, the relevant random access configuration can be obtained from the SIB1 message. The configuration information can be located on the same carrier, Coreset (Control resource set), or SearchSpace as the system information and public information, or they can be different.

[0239] If an LPWA terminal cannot obtain the first transport block of SIB1 from the cell, or if a regular eMBB terminal cannot obtain the first or second transport block of SIB1 from the cell, it is equivalent to the cell being in a barred state for the terminal. The terminal cannot complete normal camping behavior and needs to perform cell reselection under the control of network parameters to find a suitable cell again.

[0240] When a terminal is in a serving cell that simultaneously broadcasts the first and second transport blocks of SIB1, the terminal's behavior may include at least one of the following:

[0241] If it is an LPWA terminal, after obtaining the SSB and synchronization through the initial cell search, it obtains the MIB information, obtains the scheduling of the first transport block of SIB1 from the MIB information, and then receives the first transport block. After successfully obtaining the first transport block of SIB1, it can complete the camping of the serving cell, including listening to system messages and public information, listening to paging, initiating random access, etc., and then wait for its uplink and downlink service needs and communicate normally with the serving cell. Since the LPWA terminal does not have high-level capabilities, it usually does not need to read the second transport block of SIB1.

[0242] If it is a regular eMBB terminal, after obtaining the SSB and synchronization through the initial cell search, it obtains the MIB information, obtains the scheduling of the first transport block of SIB1 from the MIB information, and then receives the first transport block. After successfully obtaining the first transport block of SIB1, it cannot complete camping in the serving cell. It needs to further obtain the content of the second transport block through the scheduling information of the second transport block, and use the contents of the two transport blocks together. Only then can the eMBB terminal complete camping in the serving cell and perform at least one of the following actions: listening to system messages and public information, listening to paging, and initiating random access. Because it supports more information configuration in SIB1, it can obtain additional SIBs and new feature support, larger bandwidth random access resource configuration, more frequent paging listening, etc. The eMBB terminal can obtain better service and quickly initiate services with high bandwidth, high speed, and high service quality requirements.

[0243] It should be noted that, since the second transport block of SIB1 belongs to the basic information of the eMBB terminal, the second transport block in SIB1, like the first transport block, must be in an always broadcast state and cannot support the on-demand mode, that is, the mode of sending triggered on demand.

[0244] For Method 3: Since Methods 1 and 2 each have their own characteristics and different application scenarios and requirements, a semi-static method can be used to indicate whether to use Method 1 or Method 2. For example, in the first transport block of MIB or SIB1, 1 bit can be used to explicitly indicate whether the current serving cell supports Method 1 or Method 2. When the cell supports Method 1, the terminal operates according to Method 1; when the cell supports Method 2, the terminal operates according to Method 2.

[0245] For Mode 1, all types of UEs can complete camping after receiving the first SIB1 transport block and then perform basic data operations. For ordinary eMBB terminals, if service or data enhancement is required, they can further receive the second SIB1 transport block to obtain more and richer system configurations, thereby supporting higher-speed, higher-bandwidth, and higher-level QoS service transmission requirements. The advantage of this method is that it allows ordinary eMBB terminals to operate in a more power-efficient, wider-coverage, and lower-bandwidth mode, achieving a certain energy-saving effect. For Mode 2, only LPWA terminals can complete camping after receiving the first SIB1 transport block, while ordinary eMBB terminals must receive both the first and second SIB1 transport blocks simultaneously to complete camping. Otherwise, the cell is essentially in a barred state for the terminal, and cell reselection under network parameter control is the only option. The advantage of Method 2 is that, after independently designing the required system information for different types of terminals, the common parts or parts of LPWA terminals are designed as the first transmission block, while the incremental or different parts of ordinary eMBB terminals are designed as the second transmission block. This separate design allows different transmission blocks to have different transmission parameters. For example, the first transmission block needs to be configured with a higher number of repetitions to compensate for the characteristics of low-capacity terminal receivers or hardware deficiencies, while the second transmission block can avoid unnecessary repetitions because eMBB terminals typically have a higher number and performance of receivers, resulting in better reception capabilities. This design helps save system overhead and fully ensures the reception performance and power saving performance of different terminals.

[0246] Regarding method 4: Splitting SIB1 into two transport blocks is an optimization. If two transport blocks are not used, all information can be placed within a single SIB1 transport block. For example, configuration information can be differentiated for different types of terminals. LPWA terminals can have independent domains for targeted configuration, while some functions specific to eMBB terminals can be ignored by LPWA terminals. By considering the configuration domain or scope, different types of terminals can successfully obtain their own configurations. Alternatively, when SIB1 is transmitted within the same transport block, it can be divided into two sub-blocks. These sub-blocks can be located at specific transport resource positions, specific transport coding blocks or coding block groups, specific bit positions, or specific sub-protocol data units, etc.

[0247] Thus, the MIB or SIB1 can implicitly or explicitly indicate whether the current serving cell supports the new feature of the second transport block in SIB1. An explicit method, for example, uses 1 bit in the MIB or SIB1 to explicitly indicate whether the second transport block is supported. An implicit method, for example, uses the presence of the scheduling information field of the second transport block to indicate whether it is supported. If it is not supported, it can fall back to the mode of a single transport block. If it is supported, it can use the default mode, such as the two transport blocks supporting mode 1 or mode 2; or, the network can be further explicitly configured to support mode 1 or mode 2.
