The access network device may include a base station, a wireless local area network (WLAN) access point (AS), 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 (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the relevant field.

It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0155] To facilitate understanding of the broadcast information processing method according to the embodiment of the present application, the following related technologies are now introduced:

[0156] 1. Classification and characteristics of Ambient IoT (A-IoT) devices:

[0157] Currently, ambient IoT devices can be characterized based on their energy storage capacity and their ability to generate radio frequency signals for transmission.

[0158] Among them, A-IoT devices have one of the following energy storage capabilities:

[0159] Storage capacity 1: No ability to store energy;

[0160] Storage capacity 2: Energy can be stored up to E1 or E2 joules, where it is possible for E1 = E2;

[0161] Storage capacity3: Energy can be stored up to E2 joules.

[0162] In addition, IoT devices can be divided into three types: device A, device B, and device C, depending on their energy storage capacity and ability to generate radio frequency signals for transmission.

[0163] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0164] Device B: has energy storage but no independent signal generation, i.e. backscatter transmission, where the use of stored energy may include amplification of the reflected signal;

[0165] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0166] 2. A-IoT data or service types include the following two types:

[0167] (1) Device-originated (DO) services;

[0168] (2) Device-terminated (DT) services.

[0169] Among them, device-initiated services include device-active triggered (DO traffic includes DO autonomous, DO-A) services and device-terminated triggered (DO device-terminated triggered, DO-DTT) services.

[0170] Among them, DO data indicates that the data flow originates from the A-IoT device; DT data indicates that the data flow is transmitted to the A-IoT device.

[0171] Data streams originating from A-IoT devices (i.e., DO data) can be further categorized into the following two types:

[0172] DO-A, where AIoT devices autonomously initiate data transmission, for example, by connecting to a large number of various sensors that collect and, when necessary, proactively report information about the environment, devices, and organisms;

[0173] DO-DTT, where a reader / writer device such as a base station triggers an AIoT device to initiate data transmission, such as asset identification, status reporting, and tracking. These are all downlink (DL) trigger reports, with the reader collecting data from the tag by triggering inventory procedures. Because the data is generated or initiated by the IoT device, this service should be considered a DO service initiated by the tag, triggered by a reader-side control command.

[0174] 3. A-IoT system deployment scenarios can be divided into the following three scenarios:

[0175] Scenario 1: A-IoT is deployed within the NR system bandwidth, also known as in-band deployment. In this scenario, in one implementation, the same base station serves both the A-IoT device and the New Radio (NR) UE; in another implementation, different base stations serve the A-IoT device and the NR UE.

[0176] Scenario 2: A-IoT is deployed within the guard interval of the NR system, also known as guard band deployment. In this scenario, in one implementation, the same base station serves both the A-IoT device and the NR UE. In another implementation, different base stations serve the A-IoT device and the NR UE.

[0177] Scenario 3: A-IoT is deployed outside the NR system's guard interval (and obviously, outside the NR system bandwidth), also known as stand-alone deployment. In this scenario, the base station typically only serves A-IoT devices.

[0178] The following describes in detail the broadcast information processing method provided by the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0179] In a first aspect, an embodiment of the present application provides a method for processing broadcast information. As shown in FIG2 , the method may include the following step 201:

[0180] Step 201: The first device obtains broadcast information.

[0181] The first device may be a terminal device, such as an Internet of Things device.

[0182] Furthermore, with the development of IoT technology, the Ambient IoT (A-IoT) technology has emerged. This technology integrates various possible technological approaches around a specific goal to quickly and accurately collect, transmit, and apply environmental and related information. Therefore, the first device can optionally be an A-IoT device.

[0183] In addition, the broadcast information is used to indicate (for example, carry) at least one of the following items A-1 to A-5:

[0184] Item A-1: ​​Access control information, which indicates whether access to the cell is permitted, whether further cell admission information needs to be obtained, and at least one of the access conditions permitted by the cell;

[0185] Item A-2: frequency domain position indication information of a synchronization grid or a channel grid; the frequency domain position information of the synchronization grid or the channel grid is used to indicate the frequency domain position of the broadcast information;

[0186] Item A-3: Inventory or paging monitoring indication information, which indicates whether to monitor control information in ambient IoT communications (including at least one of a paging command, an inventory command, and a selection command) and whether to further obtain at least one item of inventory or paging group indication information;

[0187] Item A-4: Frequency domain related information of environmental IoT communications;

[0188] In one embodiment, the above-mentioned broadcast information may be broadcast information of environmental Internet of Things communication, that is, at least one of the above-mentioned items A-1 to A-4 may be included (that is, carried) in the broadcast information of environmental Internet of Things communication.

[0189] Item A-5: Rate matching indication information.

[0190] In one embodiment, the rate matching indication information is used to indicate resource information that is unavailable for environmental Internet of Things communication, which can also be understood as the rate matching indication information being used to indicate information on resource mapping that is not used for environmental Internet of Things communication.

[0191] Optionally, the frequency domain related information of the non-environmental Internet of Things communication can also be indicated in the broadcast information of the environmental Internet of Things communication, so that the environmental Internet of Things communication can know which resources cannot be used based on the resource information occupied by the non-environmental Internet of Things.

[0192] Similarly, optionally, in the case where the broadcast information in the above step 201 is the broadcast information of the environmental Internet of Things communication, the frequency domain related information of the environmental Internet of Things communication is also carried in the broadcast information of the non-environmental Internet of Things communication, so that the non-environmental Internet of Things communication can know which resources cannot be used based on the resource information occupied by the environmental Internet of Things.

[0193] In one embodiment, at least one item of frequency domain related information of environmental Internet of Things communications is carried in at least one of the following:

[0194] Broadcast information for ambient IoT communications;

[0195] Broadcast information for non-ambient IoT communications.

[0196] Exemplarily, part of the frequency domain related information of environmental Internet of Things communication is carried in the broadcast information of environmental Internet of Things communication, and the remaining information is carried in the broadcast information of non-environmental Internet of Things communication; or, all the information in the frequency domain related information of environmental Internet of Things communication is carried in the broadcast information of environmental Internet of Things communication; or, all the information in the frequency domain related information of environmental Internet of Things communication is carried in the broadcast information of non-environmental Internet of Things communication.

[0197] As can be seen from the above step 201, in an embodiment of the present application, the first device is able to obtain broadcast information, and the broadcast information is used to indicate at least one of the following: access control information, frequency domain position indication information of the synchronization grid or channel grid, inventory or paging monitoring indication information, frequency domain related information of environmental Internet of Things communication, and rate matching indication information. It can be seen that in an embodiment of the present application, at least one of the aforementioned information can be indicated in the broadcast information, so that the first device can obtain at least one of the aforementioned information from the broadcast information to facilitate initial access. Therefore, in an embodiment of the present application, the necessary broadcast information required for the initial access of the Internet of Things device is provided, which solves the problem in the related art that the necessary broadcast information required for the environmental Internet of Things device to access the reader / writer device is not provided, thereby causing the Internet of Things device to be unable to make an initial connection.

[0198] Optionally, the broadcast information includes at least one of a master information block (ie, a master system information block, MIB) and physical layer indication information; it is understandable that the physical layer indication information is added when the physical layer processes the MIB.

[0199] It can be understood that at least one of the above information A-1 to A-4 can be carried in at least one of the main information block and the physical layer indication information.

[0200] Optionally, the broadcast information is carried on at least one of a low-power synchronization signal and a physical broadcast channel (in environmental Internet of Things communication).

[0201] It can be understood that at least one of the information in A-1 to A-4 above can be carried in at least one of the low-power synchronization signal and the physical broadcast channel.

[0202] Optionally, the access control information includes at least one of the following items B-1 to B-5:

[0203] Item B-1: cell admission indication information, which indicates whether access to the cell is allowed;

[0204] It can be understood that the cell admission indication information may correspond to a cell, that is, one cell has one cell admission indication information, and the cell admission indication information is used to indicate whether access to the cell that sends the broadcast information is allowed.

[0205] Item B-2: whether to obtain cell admission indication information;

[0206] In the case described in item B-2, the access control information may not include the cell admission indication information; illustratively, if the access control information is carried in the MIB, then the cell admission indication information may not be carried in the MIB, but may be carried in other system information, but the MIB carries an indication of whether to obtain the cell admission indication information. In this way, it can be determined whether to obtain the cell admission indication information based on the indication carried in the MIB. If necessary, the cell admission indication information can be obtained in other system information, and then based on the obtained cell admission indication information, it can be determined whether the cell to which the cell admission indication information belongs can be accessed.

[0207] Optionally, the cell admission indication information includes specific cell admission conditions, device types required for cell admission, device capabilities, etc.

[0208] Item B-3: indication of the service type of the access cell, the service type including device-initiated service and / or device-terminated service;

[0209] In one embodiment, the indication of the service type of the access cell is used to indicate the service type allowed by the cell, that is, devices that support the service type allowed by the cell can access the cell, that is, if the service type supported by a device is included in the service type allowed by the cell, then the device can access the cell.

[0210] Alternatively, in another embodiment: the indication of the service type of the admission cell is used to indicate whether a device supporting a predetermined service type is allowed to access the cell, wherein the predetermined service type may include a device-initiated service and a device-terminated service.

[0211] It is understood that the indication of the service type of the admission cell can correspond to the cell, that is, if a cell has an indication of the service type of the admission cell, the indication of the service type of the admission cell is used to indicate the service type allowed by the cell to which it belongs. For example, the indication of the service type of the admission cell of a certain cell indicates that the cell allows device termination type services, and devices that support device termination type services can access the cell.

[0212] Optionally, the device-initiated service includes at least one of a device-actively-initiated service and a device-passively-triggered service.

[0213] Item B-4: Indication of the power level of the equipment admitted to the cell;

[0214] In one embodiment, the indication of the device power level of the admitted cell is used to indicate the device power level allowed by the cell, that is, devices using the device power level allowed by the cell can access the cell.

[0215] In another embodiment, the indication of the device power level of the admitted cell is used to indicate whether a device supporting a predetermined device power level is allowed to access the cell.

[0216] For example, the power class may include at least one of a 0 decibel milliwatt power class (dBm power class) and a -10 dBm power class.

[0217] It is understood that the indication of the device power level of the access cell can correspond to the cell, that is, if there is an indication of the device power level of the access cell for a cell, then the indication of the device power level of the access cell is used to indicate the device power level allowed by the cell to which it belongs. For example, if the indication of the device power level of the access cell of a cell indicates that the cell allows 0dBm power class, then devices using 0dBm power class can access the cell.

[0218] As can be seen from the above items B-1 to B-4, in one embodiment, the access device can be managed from the aspects of access control, service type, and device power in combination with the service type or device power level of the access cell. For example, the steps for a terminal to determine whether it can access a cell are:

[0219] 1) First, confirm that the cell admission indication information is true;

[0220] 2) Determine whether the terminal meets the service type or device power level required to enter the cell.

[0221] A cell can only be accessed if both 1) and 2) are met; otherwise, if 1) is not met, the cell is directly determined to be a prohibited cell. It is understood that if the terminal searches for multiple cells and meets 1) and 2) for each of the multiple cells, the specific method for determining which cell to access can be determined using existing cell selection methods.

[0222] Item B-5: Indication of the device type for access to the cell, the device type including: at least one device type determined based on the energy storage capacity of the IoT device and the ability to generate radio frequency signals for transmission, for example, the device type includes at least one of the aforementioned device A, device B, and device C.

[0223] In one embodiment, the indication of the device type allowed to enter the cell is used to indicate the device type allowed by the cell, that is, devices belonging to the device type allowed by the cell can access the cell.

[0224] Alternatively, in another embodiment: the indication of the device type admitted to the cell is used to indicate whether a device supporting a predetermined device type is allowed to access the cell.

[0225] It is understood that the indication of the device type of the admission cell can correspond to the cell, that is, if a cell has an indication of the device type of the admission cell, the indication of the device type of the admission cell is used to indicate the device type allowed by the cell to which it belongs. For example, if the indication of the device type of the admission cell of a cell indicates that the cell allows device A to access, then device A can access the cell.

[0226] It should be noted that the above device types may also be referred to as device power consumption types.

[0227] As can be seen from the above, in one embodiment, the access control information may correspond to a cell, that is, there is one access control information for each cell. In this way, each cell may broadcast its own access control information through broadcast information.

[0228] Optionally, the frequency domain position indication information of the synchronization grid or the channel grid satisfies at least one of the following C-1 to C-2:

[0229] Item C-1: The frequency domain position indication information of the synchronization grid or the channel grid includes: index information of the synchronization grid or the channel grid;

[0230] Optionally, at least part of the synchronization grid index information or at least part of the channel grid index information in the frequency domain position indication information of the synchronization grid or channel grid may be included in the MIB, and the rest may be carried in the physical layer indication information.

[0231] For example, the broadcast information only includes an indication of the least significant bit (LSB) of the X bits in the index. Optionally, an additional Y most significant bits (MSBs) are indicated in system information other than the broadcast information, such as the Y bits in the first system information block (SIB1). That is, the complete index information is carried by the X+Y bits.

[0232] Alternatively, for example, the MIB only includes an indication of the LSB of the X bits in the index, and the additional MSB of the Y bits are indicated in the above-mentioned physical layer indication information.

[0233] Optionally, the step size of the synchronization grid or the channel grid is 100 (KHz) or 200Khz. It is understandable that the index of the synchronization grid or the channel grid can be agreed upon by a protocol.

[0234] Furthermore, in some cases, directly indicating the position or number of the raster may be too large. For more efficient indication, in one case, the raster can be numbered within the bandwidth of the AIoT communication. In another case, the relative raster ID can be indicated based on the maximum possible frequency deviation of the AIoT device. For example, assuming the maximum frequency deviation of the AIoT device is 180kHz, and the sync raster is configured in steps of 100kHz, since the 180kHz frequency deviation only spans two sync rasters, the AIoT device cannot identify which of the two sync rasters the currently received broadcast information corresponds to. In this case, a 1-bit raster ID (0 or 1) can be used to indicate the target raster, thereby achieving the purpose of correcting the frequency deviation.

[0235] Item C-2: The frequency domain position indication information of the synchronization grid or channel grid is associated with the deployment mode of the environmental Internet of Things, that is, part or all of the frequency domain position indication information of the synchronization grid or channel grid is related to the deployment mode of the environmental Internet of Things.

[0236] Optionally, the association relationship between the frequency domain position indication information of the synchronization grid or the channel grid and the deployment mode of the environmental Internet of Things satisfies at least one of the following:

[0237] Frequency domain position indication information of the synchronization grid or channel grid in the in-band deployment mode;

[0238] Frequency domain position indication information of the synchronization grid or channel grid in the protection bandwidth deployment mode;

[0239] In standalone deployment mode, there is no frequency domain position indication information for the synchronization grid or channel grid.

[0240] It can be seen from this that in one embodiment, in the in-band deployment and protection bandwidth deployment modes, the frequency domain position indication information of the synchronization grid or channel grid can be configured; in the independent deployment mode, the frequency domain position indication information of the synchronization grid or channel grid can be not configured. Among them, the frequency domain position indication information of the synchronization grid or channel grid associated with the in-band deployment and protection bandwidth deployment modes can be the same or different. It should be noted that the difference here refers to the possible different value ranges of the frequency domain position.

[0241] It should be noted that in the above-mentioned standalone deployment mode, frequency domain-related information for ambient IoT communications can be associated. In standalone deployment mode, the relative position information of the frequency domain location where the broadcast information is received relative to the initial access bandwidth part (BWP) is configured. The initial access BWP can be understood as the bandwidth where other system information is received, such as the bandwidth where SIBx messages are received.

[0242] Optionally, the inventory or paging monitoring indication information satisfies at least one of the following items D-1 to D-3:

[0243] Item D-1: The transmission period of the inventory or paging monitoring indication information is an integer multiple of the transmission period of the broadcast information;

[0244] Item D-2: The inventory or paging monitoring indication information is transmitted at the specific transmission timing of the broadcast information; that is, the inventory or paging monitoring indication information is not transmitted at a timing other than the specific transmission timing of the broadcast information;

[0245] Item D-3: The inventory or paging monitoring indication information and other information are transmitted in different information blocks, that is, the inventory or paging monitoring indication information and other information occupy different time domain resources; the other information includes at least one item of information in the information indicated by the broadcast information except the inventory or paging monitoring indication information.

[0246] Exemplarily, in one embodiment, the other information and the inventory or paging monitoring indication information are transmitted in different blocks, for example, the other information is transmitted on block 1, and the inventory or paging monitoring indication information is transmitted on block 2; optionally, the transmission period of block 2 is different from the transmission period of block 1; for example, the period of block 2 is equal to the paging or inventory period (for example, 1280ms), and block 2 is transmitted at a specific transmission timing of the broadcast information, as shown in Figure 3, it can be seen that the period of block 2 is four times that of block 1; for example, if the period of block 1 is 320ms, then the period of block 2 is 4*320ms=1280ms.

[0247] Optionally, the offset of the inventory or paging monitoring indication information or block 2 can be one of 0, 1, 2, and 3; the offset is relative to block 1. An offset of 0 means that the first broadcast information transmission opportunity starting from system frame number (SFN) 0 includes blocks 1 and 2, as shown in FIG3 ; an offset of 1 means that the second broadcast information transmission opportunity starting from SFN0 includes blocks 1 and 2, as shown in FIG4 ; similarly, an offset of 2 means that the third broadcast information transmission opportunity starting from SFN0 includes blocks 1 and 2; an offset of 3 means that the fourth broadcast information transmission opportunity starting from SFN0 includes blocks 1 and 2.

[0248] It should be noted that, for exemplary purposes, in Figures 3 to 4, starting from SFN0, each cell contains 8 system frames, that is, each cell occupies 80ms.

[0249] Optionally, the frequency domain related information of the environmental Internet of Things communication includes at least one of the following items E-1 to E-4:

[0250] E-1: Environmental Internet of Things communication bandwidth;

[0251] Item E-2: Frequency domain separation between ambient IoT communications and non-ambient IoT communications;

[0252] Item E-3: The relative starting frequency domain position information of the ambient IoT communication bandwidth. The relative starting frequency domain position information may be relative to non-ambient IoT communication, for example, the frequency domain position information of the ambient IoT communication bandwidth relative to the NR communication bandwidth;

[0253] Item E-4: Frequency hopping indication information for ambient IoT communications, such as configuring ambient IoT communications to support frequency hopping at a certain time granularity. Optionally, the frequency domain granularity of the frequency hopping may be at the resource block (RB) level, carrier level, or subcarrier level.

[0254] Optionally, the rate matching indication information includes unavailable resource pattern information, wherein the unavailable resource pattern information includes at least one of the following items V-1 to V-5:

[0255] Item V-1: Information on unavailable symbols;

[0256] V-2 item: information about unavailable subframes;

[0257] V-3 item: information of unavailable system frame;

[0258] V-4 item: unavailable frequency domain information;

[0259] Item V-5: Period information of the unavailable resource pattern.

[0260] It should be noted that the time domain resources occupied by the unavailable resource pattern are not used for ambient IoT communications.

[0261] The reader, ie, the second device (eg, a network-side device), skips the unavailable resources and performs resource mapping.

[0262] Optionally, the broadcast information is divided into at least one information block for transmission;

[0263] The at least one information block satisfies at least one of the following items F-1 to F-7:

[0264] Item F-1: adding a cyclic redundancy check (CRC) to the at least one information block separately;

[0265] Item F-2: the at least one information block is separately channel coded;

[0266] Item F-3: the at least one information block is individually scrambled;

[0267] Item F-4: The at least one information block is self-decodable;

[0268] Item F-5: Multiple information blocks occupy different time domain resources;

[0269] Item F-5: Multiple information blocks occupy different frequency domain resources;

[0270] Item F-7: The transmission periods of multiple information blocks are the same or different.

[0271] It can be seen from this that in one embodiment, different transmission blocks transmitting broadcast information can have CRC added separately, channel coding performed separately, and at least one of scrambling and self-decoding performed separately; at least one of the time domain resources and frequency domain resources occupied by different transmission blocks can also be different; and the transmission periods of different transmission blocks can also be different.

[0272] For example, inventory or paging monitoring indication information and other information (including other information in broadcast information other than inventory or paging monitoring indication information) are transmitted in different blocks, for example, transmitted on block 1 and block 1 respectively, where block 1 and block 2 can meet at least one of the above F-1 to F-7.

[0273] Optionally, the method further comprises at least one of the following steps J-1 to J-4:

[0274] Step J-1: When the broadcast information indicates the access control information, the first device determines whether it is allowed to access the cell or determines whether to obtain cell admission indication information based on the access control information.

[0275] It can be understood that, when the access control information included in the broadcast information includes cell admission indication information, the first device determines whether it is allowed to access the cell based on the cell admission indication information; when the access control information included in the broadcast information includes an indication of whether to obtain the cell admission indication information, the first device determines whether to obtain the cell admission indication information based on the indication of whether to obtain the cell admission indication information.

[0276] Step J-2: When the broadcast information indicates frequency domain position indication information of the synchronization grid or channel grid, the first device determines the frequency domain position of the broadcast information (e.g., the frequency domain position of the broadcast channel) according to the frequency domain position indication information of the synchronization grid or channel grid;

[0277] Step J-3: When the broadcast information indicates rate matching indication information, the first device receives and demodulates data according to the rate matching indication information;

[0278] In one embodiment, the rate matching indication information is used to indicate resource information that is unavailable in the environmental Internet of Things, and the first device can receive and demodulate data in other resources other than the resources indicated by the rate matching indication information.

[0279] Step J-4: When the broadcast information indicates the inventory or paging monitoring indication information, the first device determines at least one of the following based on the inventory or paging monitoring indication information:

[0280] Whether to start monitoring control information in ambient IoT communications, wherein the control information includes at least one of a paging command, an inventory command, and a selection command;

[0281] Whether to obtain inventory or paging group indication information, where the inventory or paging group indication information is used to indicate whether the first device of one or more groups starts monitoring control information, where the group is a grouping of IoT devices.

[0282] It should be noted that if the first device is instructed to monitor inventory or paging, the first device begins monitoring control information. If the first device is instructed not to monitor inventory or paging, the first device skips monitoring control information. This allows the terminal to flexibly save energy by monitoring control information. For example, the control information may be an inventory command, a selection command, or a paging command. The inventory command can be understood as a command instructing the first device to begin an inventory.

[0283] In one embodiment, the MIB carries inventory or paging monitoring indication information. Due to limited bits, for example, only one bit of indication information is used to instruct all first devices to monitor or not monitor control information. In order to indicate whether the first device monitors control information in a finer granularity, the inventory or paging group indication information can be carried in other system information (SIBX) in addition to the MIB. That is, an indication is made to the first device of each group whether it monitors control information. In this case, the first device only needs to monitor the control information in the environmental Internet of Things communication when it determines that the group it is in or the associated group needs to monitor the control information in the environmental Internet of Things communication.

[0284] It can be understood that the inventory or paging monitoring indication information can be understood as indication information indicating whether to monitor the inventory monitoring group indication information.

[0285] Optionally, the broadcast information further indicates (for example, carries) at least one of the following items H-1 to H-6:

[0286] Item H-1: Time synchronization information;

[0287] The time synchronization information may include synchronization information of a time unit of the ambient IoT communication, such as at least one of a system frame level and a superframe level;

[0288] Item H-2: Cell identification information;

[0289] Item H-3: first system information block SIB1 scheduling related information;

[0290] After the first device obtains the SIB1 scheduling information indicated by the broadcast information, it can demodulate the SIB1 scheduling information at a corresponding position or directly demodulate the SIB1 information according to the SIB1 scheduling information.

[0291] Item H-4: Deployment mode information of the environmental Internet of Things, where the deployment mode includes at least one of the in-band deployment mode, protected bandwidth deployment mode, and standalone deployment mode described above;

[0292] Item H-5: System information SI update indication information;

[0293] Among them, when the first device receives the SI update indication information, if it indicates that the SI information has been updated, the first device goes to the corresponding SI receiving position to receive the updated SI information; if it indicates that the SI information has not been updated, there is no need to detect and demodulate the SI information; thus saving power consumption of monitoring SI information.

[0294] Item H-6: Earthquake and Tsunami Warning System (ETWS) notification information.

[0295] Since ETWS notification information carries earthquake and tsunami notifications, its importance and timeliness are very high. In the embodiment of the present application, ETWS notification information can be carried in broadcast information (such as MIB). Since the transmission period of broadcast information is more frequent than SIB, carrying ETWS notification information by broadcast information can achieve the effect of reducing earthquake and tsunami notification delay.

[0296] Optionally, the change or update period of the broadcast information is greater than or equal to the transmission period of the low-power synchronization signal; wherein, the low-power synchronization signal is used for at least one of synchronization and measurement; in addition, the sending period of the broadcast information can be agreed upon by the protocol.

[0297] In a second aspect, an embodiment of the present application further provides a method for processing broadcast information. As shown in FIG5 , the method may include the following step 501:

[0298] Step 501: The second device sends broadcast information;

[0299] The second device may be a network-side device (eg, a base station).

[0300] In addition, the broadcast information is used to indicate (for example, carry) at least one of the following items A-1 to A-5:

[0301] Item A-1: ​​Access control information;

[0302] Item A-2: Frequency domain position indication information of the synchronization grid or channel grid;

[0303] Item A-3: Inventory or paging monitoring indication information;

[0304] Item A-4: Frequency domain related information of environmental IoT communications;

[0305] Item A-5: Rate matching indication information.

[0306] The relevant explanations for items A-1 to A-4 can be found in the previous text and will not be repeated here.

[0307] As can be seen from the above step 501, in an embodiment of the present application, the second device is able to send broadcast information, and the broadcast information is used to indicate at least one of the following: access control information, frequency domain position indication information of the synchronization grid or channel grid, inventory or paging monitoring indication information, frequency domain related information of environmental Internet of Things communication, and rate matching indication information. It can be seen that in an embodiment of the present application, at least one of the aforementioned information can be indicated in the broadcast information, so that the first device can obtain the aforementioned at least one of the aforementioned information from the broadcast information to facilitate initial access. Therefore, in an embodiment of the present application, the necessary broadcast information required for the initial access of the Internet of Things device is provided, which solves the problem in the related art that the necessary broadcast information required for the environmental Internet of Things device to access the reader / writer device is not provided, thereby causing the Internet of Things device to be unable to make an initial connection.

[0308] Optionally, the broadcast information includes at least one of a master information block (ie, a master system information block, MIB) and physical layer indication information; it is understandable that the physical layer indication information is added when the physical layer processes the MIB.

[0309] It can be understood that at least one of the above information A-1 to A-4 can be carried in at least one of the main information block and the physical layer indication information.

[0310] Optionally, the broadcast information is carried on at least one of a low-power synchronization signal and a physical broadcast channel (in environmental Internet of Things communication).

[0311] It can be understood that at least one of the information in A-1 to A-4 above can be carried in at least one of the low-power synchronization signal and the physical broadcast channel.

[0312] Optionally, the access control information includes at least one of the following items B-1 to B-5:

[0313] Item B-1: cell admission indication information, which indicates whether access to the cell is allowed;

[0314] Item B-2: whether to obtain cell admission indication information;

[0315] Item B-3: indication of the service type of the access cell, the service type including device-initiated service and / or device-terminated service;

[0316] Item B-4: Indication of the power level of the equipment admitted to the cell;

[0317] Item B-5: An indication of the device type for access to the cell, the device type comprising: at least one device type determined based on the energy storage capacity of the IoT device and the ability to generate radio frequency signals for transmission.

[0318] For the relevant explanations of items B-1 to B-5, please refer to the above text and will not be repeated here.

[0319] Optionally, the device-initiated service includes at least one of the following:

[0320] Device proactively initiates services;

[0321] Device passive triggering services.

[0322] Optionally, the frequency domain position indication information of the synchronization grid or the channel grid satisfies at least one of the following C-1 to C-2:

[0323] Item C-1: The frequency domain position indication information of the synchronization grid or the channel grid includes: index information of the synchronization grid or the channel grid;

[0324] Item C-2: The frequency domain position indication information of the synchronization grid or channel grid is associated with the deployment mode of the environmental Internet of Things.

[0325] The relevant explanations for items C-1 to C-2 can be found in the previous text and will not be repeated here.

[0326] Optionally, the association relationship between the frequency domain position indication information of the synchronization grid or the channel grid and the deployment mode of the environmental Internet of Things satisfies at least one of the following:

[0327] Frequency domain position indication information of the synchronization grid or channel grid in the in-band deployment mode;

[0328] Frequency domain position indication information of the synchronization grid or channel grid in the protection bandwidth deployment mode;

[0329] In standalone deployment mode, there is no frequency domain position indication information for the synchronization grid or channel grid.

[0330] It can be seen from this that in one embodiment, in the in-band deployment and protection bandwidth deployment modes, the frequency domain position indication information of the synchronization grid or channel grid can be configured; in the independent deployment mode, the frequency domain position indication information of the synchronization grid or channel grid can be not configured. Among them, the frequency domain position indication information of the synchronization grid or channel grid associated with the in-band deployment and protection bandwidth deployment modes can be the same or different. It should be noted that the difference here refers to the possible different value ranges of the frequency domain position.

[0331] Optionally, the inventory or paging monitoring indication information satisfies at least one of the following items D-1 to D-3:

[0332] Item D-1: The transmission period of the inventory or paging monitoring indication information is an integer multiple of the transmission period of the broadcast information;

[0333] Item D-2: The inventory or paging monitoring indication information is transmitted at the specific transmission timing of the broadcast information;

[0334] Item D-3: The inventory or paging monitoring indication information and other information are transmitted in different information blocks, and the other information includes at least one item of information indicated by the broadcast information except the inventory or paging monitoring indication information.

[0335] The relevant explanations for items D-1 to D-3 can be found in the previous text and will not be repeated here.

[0338] Item E-2: Frequency domain separation between ambient IoT communications and non-ambient IoT communications;

[0339] Item E-3: The relative starting frequency domain position information of the ambient IoT communication bandwidth. The relative starting frequency domain position information may be relative to non-ambient IoT communication, for example, the frequency domain position information of the ambient IoT communication bandwidth relative to the NR communication bandwidth;

[0340] Item E-4: Frequency hopping indication information for ambient IoT communications, such as configuring the ambient IoT to support frequency hopping at a certain time granularity within the non-ambient IoT bandwidth.

[0341] Optionally, in the case where the broadcast information is broadcast information of environmental Internet of Things communication, at least one item of frequency domain related information of the environmental Internet of Things communication is also carried in the broadcast information of non-environmental Internet of Things communication, so that the non-environmental Internet of Things terminal side and the network side can know which resources cannot be used.

[0342] That is, it can be understood that at least one piece of information in the frequency domain related information of the environmental Internet of Things communication is carried in at least one of the following items:

[0343] Broadcast information for ambient IoT communications;

[0344] Broadcast information for non-ambient IoT communications.

[0345] Optionally, the rate matching indication information is used to indicate resource information that is unavailable for environmental Internet of Things communication.

[0346] Optionally, the rate matching indication information includes unavailable resource pattern information;

[0347] The unavailable resource pattern information indicates at least one of the following items V-1 to V-5:

[0348] V-1 item: Unavailable symbol information;

[0349] V-2 item: Unavailable subframe information

[0350] V-3 item: Unavailable system frame information

[0351] V-4 item: unavailable frequency domain information;

[0352] Item V-5: Period information of the unavailable resource pattern.

[0353] The relevant descriptions of items V-1 to V-5 can be found in the above description and will not be repeated here. Optionally, the method further includes:

[0354] In a case where the broadcast information indicates the rate matching information, the second device performs resource mapping for environmental IoT communication according to the rate matching indication information.

[0355] Among them, the rate matching indication information is used to indicate the resource information that is unavailable for environmental Internet of Things communication. Therefore, the second device can skip the unavailable resources for resource mapping according to the above-mentioned unavailable resource pattern information included in the rate matching indication information.

[0356] Optionally, the broadcast information is divided into at least one information block for transmission;

[0357] The at least one information block satisfies at least one of the following items F-1 to F-7:

[0358] Item F-1: adding a cyclic redundancy check to the at least one information block separately;

[0359] Item F-2: the at least one information block is separately channel coded;

[0360] Item F-3: the at least one information block is individually scrambled;

[0363] Item F-5: Multiple information blocks occupy different frequency domain resources;

[0364] Item F-7: The transmission periods of multiple information blocks are the same or different.

[0365] For the relevant explanations of items F-1 to F-7, please refer to the above text and will not be repeated here.

[0366] Optionally, the broadcast information further indicates (for example, carries) at least one of the following items H-1 to H-6:

[0367] Item H-1: Time synchronization information;

[0368] Item H-2: Cell identification information;

[0369] Item H-3: first system information block SIB1 scheduling related information;

[0370] Item H-4: Information on deployment models of environmental IoT;

[0371] Item H-5: System information SI update indication information;

[0372] Item H-6: Earthquake and Tsunami Warning System (ETWS) notification information.

[0373] The relevant explanations for items H-1 to H-6 can be found in the previous article and will not be repeated here.

[0374] Optionally, the change or update period of the broadcast information is greater than or equal to the transmission period of the low-power synchronization signal; wherein, the low-power synchronization signal is used for at least one of synchronization and measurement; in addition, the sending period of the broadcast information can be agreed upon by the protocol.

[0375] As can be seen from the above, the specific implementation of the broadcast information processing method of the embodiment of the present application can be described in the following implementation modes one to three.

[0376] Implementation method 1: Broadcast information (eg, MIB) carries access control information.

[0377] The base station periodically sends broadcast information, including information necessary for initial access. The transmission process of broadcast information in the environmental Internet of Things is as follows: Steps J-1 to J-6:

[0378] Step L-1: Power on the IoT device; wherein the IoT device is a device in the environmental IoT;

[0379] Step L-2: The IoT device searches for a cell and decodes the MIB. The MIB includes access control information, which indicates whether a cell can be accessed. It should be noted that each cell has one access control information.

[0380] Step L-3: IoT device stores MIB;

[0381] Step L-4: The IoT device determines whether it can access the cell to which the access control information belongs based on the access control information in the MIB. For example, if the access control information includes an indication of the service type of the access cell, the IoT device, after obtaining the MIB, determines whether the service type supported by the IoT device is included in the type information provided in the service type indication of the access cell. If so, the IoT device executes step J-5. If not, the IoT device exits the cell.

[0382] Step L-5: If the MIB indicates SIB scheduling information, the IoT device demodulates the SIB information at the corresponding location according to the SIB scheduling information;

[0383] Step L-6: The IoT device stores the demodulated SIB and accesses the cell to which the access broadcast information belongs based on the demodulated SIB.

[0384] From the above steps, it can be seen that in environmental IoT communications, it is possible to achieve more fine-grained prohibition of devices supporting certain service types from accessing the cell through MIB indication of the service type of the access cell, thereby effectively improving the access efficiency of the cell.

[0385] Implementation method 2: inventory monitoring instruction information is carried in broadcast information (eg, MIB).

[0386] In this embodiment, the broadcast information may carry inventory monitoring indication information, wherein inventory monitoring can be understood as control channel monitoring, that is, the broadcast information may carry advance indication information of whether to monitor the control channel.

[0387] For example, a network device (e.g., a reader) periodically broadcasts information to IoT devices. If the inventory monitoring instruction carried in a particular broadcast message instructs the IoT device to monitor the inventory control channel, the IoT device begins monitoring the control channel. After a period of time, if the inventory monitoring instruction carried in the broadcast message instructs the IoT device not to monitor the control channel, the IoT device stops monitoring the control channel, thus achieving highly flexible instruction.

[0388] In addition, the broadcast information can be carried in the Low Power Synchronization Signal Block (LP-SSB). Then, while receiving the broadcast information and completing the measurement synchronization, the IoT device can also complete the reception of the above-mentioned inventory monitoring indication information, thereby saving the monitoring power consumption of the inventory monitoring indication information and reducing the monitoring power consumption of the IoT device.

[0389] Optionally, the network side can also group IoT devices (for example, by informing the IoT device's subgroup ID via a Non-Access Stratum (NAS) message) and group the grouped information to indicate the inventory monitoring indication information. For example, the network side configures four IoT device groups and uses four bits to indicate whether each of the four groups monitors the control channel. In this case, there is one piece of inventory monitoring indication information corresponding to one IoT device group.

[0390] Optionally, to avoid a ping-pong effect in inventory monitoring (i.e., monitoring of the control channel), the network configuration or protocol further stipulates the duration of each flip (from monitoring to non-listening or vice versa) of the inventory monitoring indication information indicated by the broadcast information. In other words, a minimum duration for monitoring or non-listening inventory is stipulated. During this minimum duration, the IoT device defaults to maintaining the inventory monitoring state unchanged.

[0391] Optionally, the broadcast information may further carry SI information update indication information and ETWS notification information, wherein the SI update indication information is used to indicate whether the SI information is updated.

[0392] Among them, after the IoT device receives the SI update indication information, if the indication SI information is updated, the IoT device goes to the corresponding SI receiving position to receive the updated SI information; if the indication SI information is not updated, there is no need to detect and demodulate the SI information; thus saving the power consumption of monitoring the SI information update indication.

[0393] In addition, ETWS notification information carries earthquake and tsunami notifications, so its importance and timeliness are very high. In the embodiment of the present application, ETWS notification information can be carried in broadcast information. Among them, since the transmission period of broadcast information is more frequent than SIB, carrying ETWS notification information through broadcast information can achieve the effect of reducing latency.

[0394] Implementation method three: the broadcast information (eg, MIB) carries frequency domain position indication information of the synchronization grid or channel grid.

[0395] In this embodiment, the broadcast information may carry frequency domain position indication information of the synchronization grid or channel grid, wherein the frequency domain position indication information of the synchronization grid or channel grid may include part or all of the synchronization grid or channel grid index information; the synchronization grid index and its corresponding synchronization grid frequency domain position mapping (mapping) relationship table may be agreed upon by the protocol.

[0396] The following example is explained based on the synchronized raster index.

[0397] For example, because broadcast information must ensure transmission reliability, the number of information bits that can be carried is very limited. Therefore, the least significant bit (LSB) of the X bits in the index can be indicated in the broadcast information. Optionally, additional broadcast information, such as Y bits, is indicated in system information other than the broadcast information, such as indicating Y bits in SIB1. That is, the complete index information is carried by X+Y bits.

[0398] Among them, due to the low complexity of the Internet of Things devices, the frequency deviation may be greater than 100KHz, for example, reaching 200Khz. Therefore, optionally, the synchronization grid step size may be 200Khz.

[0399] In addition, since each synchronization grid index information corresponds to a certain frequency domain position, the IoT device can obtain the corresponding certain frequency domain position based on the acquired synchronization grid index information, and thus adjust its own frequency offset according to the certain frequency domain position (i.e., perform frequency offset calibration).

[0400] Optionally, the frequency domain position indication information of the synchronization grid or the channel grid may be configured in combination with a deployment mode of the environmental Internet of Things.

[0401] For example, in in-band and guard bandwidth deployment modes, frequency domain position indication information for the synchronization grid or channel grid is configured; in standalone deployment mode, no frequency domain position indication information for the synchronization grid or channel grid is configured. The frequency domain position indication information for the synchronization grid or channel grid associated with the in-band and guard bandwidth deployment modes can be the same or different. It should be noted that the difference here refers to the different ranges of frequency domain position values.

[0402] It can be seen from the above-mentioned embodiments one to three that the embodiments of the present application provide a design for the necessary system information carried by the broadcast information (such as the main information block) obtained by the IoT device during the initial access process, which is used for the initial access process of environmental IoT communication.
