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.

[0150] In order to facilitate understanding of the broadcast information processing method of the embodiment of the present application, the following related technologies are now introduced:

[0151] 1. Classification and characteristics of Ambient IoT (A-IoT) devices:

[0152] Currently, ambient IoT devices can be characterized based on their energy storage capacity and their ability to generate radio frequency signals for transmission.

[0153] Among them, A-IoT devices have one of the following energy storage capabilities:

[0154] Storage capacity 1: No ability to store energy;

[0155] Storage capacity 2: Energy can be stored up to E1 or E2 joules, where it is possible that E1 = E2;

[0156] Storage capacity3: Energy can be stored up to E2 joules.

[0157] In addition, IoT devices can be divided into three types: device A, device B, and device C, depending on the energy storage capacity of the IoT devices and their ability to generate radio frequency signals for transmission according to the environment:

[0158] Device A: no energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0159] Device B: has energy storage, no independent signal generation, i.e. backscatter transmission, the use of stored energy may include amplification of the reflected signal;

[0160] Device C: has energy storage and has independent signal generation, i.e. active RF components for transmission.

[0161] 2. A-IoT data or service types include the following two types:

[0162] (1) Device-originated (DO) services;

[0163] (2) Device-terminated (DT) services.

[0164] Among them, device-initiated services include device-actively triggered (DO traffic includes DO autonomous, DO-A) services and device-passively triggered (DO device-terminated triggered, DO-DTT) services.

[0165] 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.

[0166] For data streams originating from A-IoT devices (i.e., DO data), they can be further classified into the following two categories:

[0167] DO-A, that is, AIoT devices autonomously initiate data transmission, such as connecting a large number of various sensors that collect and actively report information about the environment, equipment, and organisms when necessary;

[0168] DO-DTT, that is, base stations and other reader devices trigger AIoT devices to initiate data transmission, such as asset identification, status reporting and tracking, which are all downlink (DL) trigger reports. Readers collect data from tags by triggering inventory procedures. Since the data is generated or initiated in the Internet of Things (IoT) device, this service should be regarded as a DO service initiated by the tag triggered by the reader-side control command.

[0169] 3. A-IoT system deployment scenarios can be divided into the following three scenarios:

[0170] Scenario 1: A-IoT is deployed in the system bandwidth of NR, also known as in-band deployment. In this scenario, in one implementation, the same base station provides services for A-IoT devices and New Radio (NR) UEs; in another implementation, different base stations provide services for A-IoT devices and NR UEs.

[0171] Scenario 2: A-IoT is deployed in the guard interval of the NR system, also known as guard band deployment. In this scenario, in one implementation, the same base station provides services for A-IoT devices and NR UEs. In another implementation, different base stations provide services for A-IoT devices and NR UEs.

[0172] Scenario 3: A-IoT is deployed outside the protection interval of the NR system (obviously, not within the NR system bandwidth), also known as stand-alone deployment. In this scenario, the base station usually only provides services for A-IoT devices.

[0173] The following is a detailed description of the broadcast information processing method provided by the embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0174] In a first aspect, an embodiment of the present application provides a method for processing broadcast information, such as Figure 2 As shown, the method may include the following step 201:

[0175] Step 201: The first device obtains broadcast information.

[0176] The first device may be a terminal device, such as an Internet of Things device.

[0177] In addition, with the development of Internet of Things technology, Ambient IoT (A-IoT) technology has emerged, which is to integrate various possible technical approaches around a specific goal to complete the collection, transmission and application of environment and related information in a fast and accurate manner. Therefore, optionally, the first device can be an A-IoT device.

[0178] In addition, the broadcast information is used to indicate (for example, carries) at least one of the following A-1 to A-5:

[0179] Item A-1: ​​access control information, where the access control information is used to indicate whether access to the cell is allowed, whether further cell admission information needs to be obtained, and at least one of the access conditions allowed by the admission cell;

[0180] 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 where the broadcast information is located;

[0181] Item A-3: Inventory or paging monitoring indication information, the inventory or paging monitoring indication information is used to indicate whether to monitor the control information in the ambient IoT communication (including at least one of the paging command, inventory command, and selection command), and whether it is necessary to further obtain at least one of the inventory or paging group indication information;

[0182] Item A-4: Frequency domain related information of environmental IoT communications;

[0183] 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.

[0184] Item A-5: Rate matching indication information.

[0185] In one embodiment, the rate matching indication information is used to indicate resource information that is unavailable for environmental Internet of Things communications, and 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 communications.

[0186] Optionally, frequency domain related information of non-environmental Internet of Things communication can also be indicated in the broadcast information of 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.

[0187] 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.

[0188] In one embodiment, at least one item of frequency domain related information of environmental Internet of Things communication is carried in at least one of the following items:

[0189] Broadcast information for ambient IoT communications;

[0190] Broadcast information for non-ambient IoT communications.

[0191] 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 rest of the information is carried in the broadcast information of non-environmental Internet of Things communication; or, all 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 frequency domain related information of environmental Internet of Things communication is carried in the broadcast information of non-environmental Internet of Things communication.

[0192] It can be seen from the above step 201 that in an embodiment of the present application, the first device can 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 a synchronization grid or a 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 that the necessary broadcast information required for the environmental Internet of Things device to access the reader / writer device is not provided in the prior art, thereby causing the Internet of Things device to be unable to make an initial connection.

[0193] Optionally, the broadcast information includes at least one of a master information block (ie, a master system information block Master 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.

[0194] 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.

[0195] 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).

[0196] It can be understood that at least one of the information A-1 to A-4 above can be carried in at least one of the low-power synchronization signal and the physical broadcast channel.

[0197] Optionally, the access control information includes at least one of the following items B-1 to B-5:

[0198] Item B-1: cell access indication information, the cell access indication information is used to indicate whether access to the cell is allowed;

[0199] It can be understood that the cell admission indication information may correspond to a cell, that is, there is one cell admission indication information for one cell, and the cell admission indication information is used to indicate whether access to the cell that sends the broadcast information is allowed.

[0200] Item B-2: whether to obtain cell admission indication information;

[0201] 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.

[0202] Optionally, the cell admission indication information includes specific cell admission conditions, device types and device capabilities required for cell admission, etc.

[0203] Item B-3: indication of the service type of the access cell, the service type including device-initiated service and / or device-terminated service;

[0204] 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 supporting 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.

[0205] Or, 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.

[0206] It can be understood that the indication of the service type of the access cell can correspond to the cell, that is, if a cell has an indication of the service type of the access cell, the indication of the service type of the access cell is used to indicate the service type allowed by the cell to which it belongs. Exemplarily, the indication of the service type of the access cell of a certain cell indicates that the cell allows device termination type services, and devices supporting device termination type services can access the cell.

[0207] Optionally, the device-initiated service includes at least one of a device-actively-initiated service and a device-passively-triggered service.

[0208] Item B-4: Indication of the power level of the equipment admitted to the cell;

[0209] 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.

[0210] 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.

[0211] 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.

[0212] It can be 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 in a cell, 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. Exemplarily, the indication of the device power level of the access cell of a cell indicates that the cell allows 0dbm power class, and devices using 0dbm power class can access the cell.

[0213] 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:

[0214] 1) First, determine that the cell admission indication information is true;

[0215] 2) Determine whether the terminal meets the service type or device power level required to enter the cell.

[0216] The cell can be accessed only if both 1) and 2) are met; otherwise, if 1) is not met, it is directly determined as a forbidden cell. It is understandable that if the terminal searches for multiple cells and the terminal meets the conditions 1) and 2) of multiple cells, in this case, how to determine which cell to access that meets the conditions can be determined by using the existing cell selection method.

[0217] Item B-5: An indication of the type of device allowed to enter the cell, wherein the device type includes: 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 device A, device B, and device C mentioned above.

[0218] In one embodiment, the indication of the device type allowed to access 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.

[0219] 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.

[0220] It is understandable that the indication of the device type of the access cell can correspond to the cell, that is, if there is an indication of the device type of the access cell in a cell, the indication of the device type of the access cell is used to indicate the device type allowed by the cell to which it belongs. Exemplarily, the indication of the device type of the access cell of a certain cell indicates that the cell allows device A to access, and device A can access the cell.

[0221] It should be noted that the above device types may also be referred to as device power consumption types.

[0222] 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 one cell, so that each cell may broadcast its own access control information through broadcast information.

[0223] 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:

[0224] 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;

[0225] Optionally, at least part of the index information of the synchronization grid or at least part of the index information of the channel grid in the frequency domain position indication information of the synchronization grid or the channel grid may be included in the MIB, and the rest may be carried in the physical layer indication information.

[0226] For example, the broadcast information only includes an indication of the least significant bit (LSB) of the X bits in the index. Optionally, the additional Y bits of the most significant bit (MSB) are indicated in other system information other than the broadcast information, for example, Y bits are indicated in the first system information (System Information Block 1, SIB1). That is, the complete index information is carried by X+Y bits.

[0227] Or, 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.

[0228] Optionally, the step size of the synchronization grid or the channel grid is 100 (KHz) or 200Khz. It can be understood that the index of the synchronization grid or the channel grid can be agreed upon by a protocol.

[0229] In addition, in some cases, directly indicating the position or number of the raster may be too large. In order to indicate more effectively, in one case, the raster can be numbered within the bandwidth (band) where the environmental Internet of Things communication is located; in another case, the relative raster ID can be indicated according to the possible maximum frequency deviation of the environmental Internet of Things device. For example, assuming that the maximum frequency deviation of the environmental Internet of Things device is 180kHz, the sync raster is configured according to a step size of 100KHz. Since the frequency deviation of 180KHz only spans 2 sync rasters, the environmental Internet of Things device cannot identify which of the two sync rasters the currently received broadcast information corresponds to. In this case, the target raster can be indicated by a 1-bit raster ID (0 or 1), thereby achieving the purpose of correcting the frequency deviation.

[0230] 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.

[0231] 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:

[0232] In the in-band deployment mode, there is frequency domain position indication information of a synchronization grid or a channel grid;

[0233] Frequency domain position indication information of the synchronization grid or channel grid in the protection bandwidth deployment mode;

[0234] In the independent deployment mode, there is no frequency domain position indication information of the synchronization grid or the channel grid.

[0235] It can be seen 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 the channel grid can be configured; in the independent deployment mode, the frequency domain position indication information of the synchronization grid or the channel grid may not be configured. Among them, the frequency domain position indication information of the synchronization grid or the channel grid associated with the in-band deployment and protection bandwidth deployment modes respectively may 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.

[0236] It should be noted that in the above-mentioned independent deployment mode, frequency domain related information of environmental IoT communication can be associated. In the independent deployment mode, the relative position information of the frequency domain position where the broadcast information is received relative to the initial access bandwidth part (BWP) will be configured; among which, the initial access BWP can be understood as the bandwidth where other system information is received, such as the bandwidth where the SIBx message is received.

[0237] Optionally, the inventory or paging monitoring indication information satisfies at least one of the following items D-1 to D-3:

[0238] 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;

[0239] 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;

[0240] 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.

[0241] 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 opportunity of the broadcast information, such as Figure 3 As shown, 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.

[0242] Optionally, the offset of the inventory or paging monitoring indication information or block 2 may be one of 0, 1, 2, and 3; the offset is relative to block 1. Wherein, the offset of 0 means that the transmission timing of the first broadcast information starting from the system frame number (SFN) 0 includes block 1 and block 2, such as Figure 3 As shown; the offset of 1 means that the second broadcast information transmission opportunity starting from SFN0 includes block 1 and block 2, such as Figure 4As shown; similarly, an offset of 2 means that the third broadcast information transmission timing starting from SFN0 includes block 1 and block 2; an offset of 3 means that the fourth broadcast information transmission timing starting from SFN0 includes block 1 and block 2.

[0243] It should be noted that the exemplary description is Figures 3 to 4 In the example, starting from SFN0, each cell contains 8 system frames, that is, each cell occupies 80ms.

[0244] 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:

[0245] Item E-1: Environmental IoT communication bandwidth;

[0246] Item E-2: Frequency separation between ambient IoT communications and non-ambient IoT communications;

[0247] Item E-3: The relative starting frequency domain position information of the environmental IoT communication bandwidth, which may be relative to non-environmental IoT communication, for example, the frequency domain position information of the environmental IoT communication bandwidth relative to the NR communication bandwidth;

[0248] Item E-4: Frequency hopping indication information of environmental Internet of Things communication, such as configuring environmental Internet of Things communication to support frequency hopping at a certain time granularity. Optionally, the frequency domain granularity of the frequency hopping can be a resource block (RB) level, a carrier level, or a subcarrier level.

[0249] 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:

[0250] Item V-1: Information on unavailable symbols;

[0251] V-2 item: information about unavailable subframes;

[0252] V-3 item: information of unavailable system frame;

[0253] V-4 item: unavailable frequency domain information;

[0254] Item V-5: period information of the unavailable resource pattern.

[0255] It should be noted that the time domain resources occupied by the unavailable resource pattern are not used for environmental Internet of Things communications.

[0256] The reader, ie, the second device (eg, a network-side device), skips the unavailable resources for resource mapping.

[0257] Optionally, the broadcast information is divided into at least one information block for transmission;

[0258] The at least one information block satisfies at least one of the following items F-1 to F-7:

[0259] Item F-1: a cyclic redundancy check (CRC) is added to the at least one information block separately;

[0260] Item F-2: the at least one information block is separately channel coded;

[0261] Item F-3: the at least one information block is scrambled separately;

[0262] Item F-4: the at least one information block is self-decodable;

[0263] Item F-5: Multiple information blocks occupy different time domain resources;

[0264] Item F-5: Multiple information blocks occupy different frequency domain resources;

[0265] Item F-7: The transmission periods of multiple information blocks are the same or different.

[0266] It can be seen from this that in one embodiment, different transmission blocks that transmit 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 may also be different; and the transmission periods of different transmission blocks may also be different.

[0267] For example, inventory or paging monitoring indication information and other information (including other information in broadcast information except 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.

[0268] Optionally, the method further comprises at least one of the following steps J-1 to J-4:

[0269] 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.

[0270] 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.

[0271] Step J-2: When the broadcast information indicates the frequency domain position indication information of the synchronization grid or the channel grid, the first device determines the frequency domain position of the broadcast information (for example, the frequency domain position of the broadcast channel) according to the frequency domain position indication information of the synchronization grid or the channel grid;

[0272] 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;

[0273] 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.

[0274] 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 according to the inventory or paging monitoring indication information:

[0275] Whether to start monitoring control information in the ambient IoT communication, wherein the control information includes at least one of a paging command, an inventory command, and a selection command;

[0276] 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 to monitor control information, where the group is a grouping of IoT devices.

[0277] It should be noted that if the first device is instructed to monitor inventory or paging, the first device starts to monitor the control information. If the first device is instructed not to monitor inventory or paging, the first device skips monitoring the control information. Thus, the terminal can flexibly monitor the control information to save energy. For example, the control information is an inventory command, a selection command, or a paging command. The inventory command can be understood as a command that instructs the first device to start an inventory.

[0278] 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 indicate whether all first devices monitor or not monitor control information. In order to indicate whether the first device monitors control information in a finer granularity, the group indication information of inventory or paging can be carried in other system information (SIBX) other than the MIB. That is, the first device of each group is instructed 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.

[0279] 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.

[0280] Optionally, the broadcast information further indicates (for example, carries) at least one of the following items H-1 to H-6:

[0281] Item H-1: Time synchronization information;

[0282] 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;

[0283] Item H-2: cell identification information;

[0284] Item H-3: first system information block SIB1 scheduling related information;

[0285] 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 according to the SIB1 scheduling information or directly demodulate the SIB1 information.

[0286] Item H-4: Deployment mode information of the environmental Internet of Things, wherein the deployment mode includes at least one of the in-band deployment mode, the protected bandwidth deployment mode, and the independent deployment mode described above;

[0287] Item H-5: System information SI update indication information;

[0288] 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, thereby saving power consumption of monitoring SI information.

[0289] Item H-6: Earthquake and Tsunami Warning System (ETWS) notification information.

[0290] For ETWS notification information, since it carries earthquake and tsunami notifications, the importance and timeliness are very high. In the embodiment of the present application, the ETWS notification information can be carried in the broadcast information (such as MIB). Since the transmission period of the broadcast information is more frequent than that of the SIB, the ETWS notification information can be carried by the broadcast information, which can achieve the effect of reducing the delay of earthquake and tsunami notifications.

[0291] 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.

[0292] In a second aspect, the present application also provides a method for processing broadcast information, such as Figure 5 As shown, the method may include the following step 501:

[0293] Step 501: The second device sends broadcast information;

[0294] The second device may be a network side device (eg a base station).

[0295] In addition, the broadcast information is used to indicate (for example, carries) at least one of the following items A-1 to A-5:

[0296] Item A-1: ​​Access control information;

[0297] Item A-2: frequency domain position indication information of the synchronization grid or channel grid;

[0298] Item A-3: Inventory or paging monitoring indication information;

[0299] Item A-4: Frequency domain related information of environmental IoT communications;

[0300] Item A-5: Rate matching indication information.

[0301] Among them, the relevant explanations of items A-1 to A-4 can be found in the above text and will not be repeated here.

[0302] It can be seen from the above step 501 that 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 a synchronization grid or a channel grid, inventory or paging monitoring indication information, frequency domain related information of environmental Internet of Things communications, 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 that the necessary broadcast information required for the environmental Internet of Things device to access the reader / writer device is not provided in the prior art, thereby causing the Internet of Things device to be unable to make an initial connection.

[0303] Optionally, the broadcast information includes at least one of a master information block (ie, a master system information block Master 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.

[0304] 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.

[0305] 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).

[0306] It can be understood that at least one of the information A-1 to A-4 above can be carried in at least one of the low-power synchronization signal and the physical broadcast channel.

[0307] Optionally, the access control information includes at least one of the following items B-1 to B-5:

[0308] Item B-1: cell access indication information, the cell access indication information is used to indicate whether access to the cell is allowed;

[0309] Item B-2: whether to obtain cell admission indication information;

[0310] Item B-3: indication of the service type of the access cell, the service type including device-initiated service and / or device-terminated service;

[0311] Item B-4: Indication of the power level of the equipment admitted to the cell;

[0312] Item B-5: An indication of the type of device allowed to enter 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.

[0313] Among them, the relevant explanations of items B-1 to B-5 can be found in the previous text and will not be repeated here.

[0314] Optionally, the device-initiated service includes at least one of the following:

[0315] Device actively initiates services;

[0316] Device passive triggering services.

[0317] 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:

[0318] 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;

[0319] 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.

[0320] Among them, the relevant explanations of items C-1 to C-2 can be found in the previous article and will not be repeated here.

[0321] 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:

[0322] In the in-band deployment mode, there is frequency domain position indication information of a synchronization grid or a channel grid;

[0323] Frequency domain position indication information of the synchronization grid or channel grid in the protection bandwidth deployment mode;

[0324] In the independent deployment mode, there is no frequency domain position indication information of the synchronization grid or the channel grid.

[0325] It can be seen 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 the channel grid can be configured; in the independent deployment mode, the frequency domain position indication information of the synchronization grid or the channel grid may not be configured. Among them, the frequency domain position indication information of the synchronization grid or the channel grid associated with the in-band deployment and protection bandwidth deployment modes respectively may 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.

[0326] Optionally, the inventory or paging monitoring indication information satisfies at least one of the following items D-1 to D-3:

[0327] 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;

[0328] Item D-2: The inventory or paging monitoring indication information is transmitted at the specific transmission timing of the broadcast information;

[0329] 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.

[0330] Among them, the relevant explanations of items D-1 to D-3 can be found in the previous article and will not be repeated here.

[0331] 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:

[0335] Item E-4: Frequency hopping indication information for environmental IoT communications, such as configuring the environmental IoT to support frequency hopping at a certain time granularity within the non-environmental IoT bandwidth.

[0336] 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.

[0337] That is, it can be understood that at least one item of the frequency domain related information of the environmental Internet of Things communication is carried in at least one of the following items:

[0338] Broadcast information for ambient IoT communications;

[0339] Broadcast information for non-ambient IoT communications.

[0340] Optionally, the rate matching indication information is used to indicate resource information that is unavailable for environmental Internet of Things communications.

[0341] Optionally, the rate matching indication information includes unavailable resource pattern information;

[0342] The unavailable resource pattern information indicates at least one of the following V-1 to V-5:

[0343] V-1 item: Unavailable symbol information;

[0344] V-2 item: Unavailable subframe information

[0345] V-3 item: Unavailable system frame information

[0346] V-4 item: unavailable frequency domain information;

[0347] Item V-5: period information of the unavailable resource pattern.

[0348] 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:

[0349] In a case where the broadcast information indicates the rate matching information, the second device performs resource mapping for environmental Internet of Things communication according to the rate matching indication information.

[0350] 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.

[0351] Optionally, the broadcast information is divided into at least one information block for transmission;

[0352] The at least one information block satisfies at least one of the following items F-1 to F-7:

[0353] Item F-1: adding a cyclic redundancy check to the at least one information block separately;

[0354] Item F-2: the at least one information block is separately channel coded;

[0355] Item F-3: the at least one information block is scrambled separately;

[0359] Item F-7: The transmission periods of multiple information blocks are the same or different.

[0360] Among them, the relevant explanations of items F-1 to F-7 can be found in the previous article and will not be repeated here.

[0361] Optionally, the broadcast information further indicates (for example, carries) at least one of the following items H-1 to H-6:

[0365] Item H-4: Information on deployment models of environmental IoT;

[0366] Item H-5: System information SI update indication information;

[0367] Item H-6: Earthquake and Tsunami Warning System (ETWS) notification information.

[0368] The relevant explanations of items H-1 to H-6 can be found in the previous article and will not be repeated here.

[0369] 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.

[0370] From the above, it can be seen that 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.

[0371] Implementation method 1: Access control information is carried in broadcast information (eg MIB).

[0372] The base station periodically sends broadcast information, including information necessary for initial access, etc. The transmission process of broadcast information in the environmental Internet of Things is as follows: Steps J-1 to J-6:

[0373] Step L-1: The IoT device is powered on and turned on; wherein the IoT device is a device in the environmental IoT;

[0374] Step L-2: The IoT device searches for a cell and decodes the MIB, where the MIB includes access control information, which is used to indicate whether a cell can be accessed. It should be noted that one cell corresponds to one access control information.

[0375] Step L-3: IoT device stores MIB;

[0376] 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 obtains the MIB and determines whether the service type supported by itself is included in the type information given in the service type indication of the access cell; if so, execute step J-5; if not, exit access to the cell;

[0377] Step L-5: If the SIB scheduling information is indicated in the MIB, the IoT device demodulates the SIB information at the corresponding location according to the SIB scheduling information;

[0378] Step L-6: The IoT device stores the demodulated SIB, and accesses the cell to which the above access broadcast information belongs according to the demodulated SIB.

[0379] It can be seen from the above steps that in environmental IoT communications, it is possible to prohibit devices supporting certain service types from accessing the cell in a more fine-grained manner by indicating the service type of the cell through MIB, thereby effectively improving the access efficiency of the cell.

[0380] Implementation method 2: Broadcast information (such as MIB) carries inventory monitoring indication information.

[0381] In this embodiment, the broadcast information may carry inventory monitoring indication information, wherein inventory monitoring may be understood as control channel monitoring, that is, the broadcast information may carry advance indication information of whether to monitor the control channel.

[0382] For example, a network-side device (e.g., a reader) periodically broadcasts broadcast information to an IoT device; if the inventory monitoring indication information carried in a broadcast information at a certain time instructs the IoT device to monitor the inventory control channel, the IoT device starts to monitor the control channel. After a period of time, if the inventory monitoring indication information carried in the broadcast information indicates that the IoT device does not need to monitor the control channel, the IoT device exits monitoring the control channel, thereby achieving very flexible indication.

[0383] In addition, the broadcast information can be carried in a 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 further reducing the monitoring power consumption of the IoT device.

[0384] Optionally, the network side may also group the IoT devices (for example, inform the IoT device of the subgroup ID through a non-access stratum (NAS) message), and indicate the inventory monitoring indication information in groups. For example, the network side configures 4 groups of IoT devices, and uses 4 bits to indicate whether the 4 groups monitor the control channel. In this case, there is one inventory monitoring indication information corresponding to one group of IoT devices.

[0385] Optionally, in order to avoid the ping-pong effect of inventory monitoring behavior (i.e., the behavior of monitoring the control channel), the network side configuration or protocol further stipulates the duration of each flip (referring to switching from monitoring to non-monitoring or from non-monitoring to non-monitoring) of the inventory monitoring indication information indicated by the broadcast information. In other words, the minimum duration of monitoring or non-monitoring inventory is stipulated. During this minimum duration, the IoT device defaults to the inventory monitoring state not changing.

[0386] Optionally, the broadcast information may also 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.

[0387] Among them, after the IoT device receives the SI update indication information, if the indication SI information has been updated, the IoT device goes to the corresponding SI receiving position to receive the updated SI information; if the indication SI information has not been updated, there is no need to detect and demodulate the SI information; thus saving the power consumption of monitoring the SI information update indication.

[0388] In addition, for ETWS notification information, since it carries earthquake and tsunami notifications, the importance and timeliness are very high. In the embodiment of the present application, ETWS notification information can be carried in the broadcast information. Among them, since the transmission period of the broadcast information is more frequent than that of the SIB, the ETWS notification information is carried by the broadcast information, so the effect of reducing the delay can be achieved.

[0389] Implementation method three: the broadcast information (eg, MIB) carries frequency domain position indication information of the synchronization grid or the channel grid.

[0390] In this embodiment, the broadcast information may carry frequency domain position indication information of the synchronization grid or the channel grid, wherein the frequency domain position indication information of the synchronization grid or the 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.

[0391] The following example is explained in terms of synchronized raster indexes.

[0392] Exemplarily, since the broadcast information needs to 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 other 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.

[0393] Among them, due to the low complexity of the Internet of Things equipment, the frequency deviation may be greater than 100KHz, for example, reaching 200Khz. Therefore, optionally, the synchronization grid step size may be 200Khz.

[0394] 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).

[0395] 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.

[0396] For example, in the in-band deployment and protection bandwidth deployment modes, the frequency domain position indication information of the synchronization grid or channel grid will be configured; in the independent deployment mode, the frequency domain position indication information of the synchronization grid or channel grid will not be 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.

[0397] It can be seen from the above-mentioned embodiments one to three that the embodiments of the present application provide a design for 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.
