[0037] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0038] In this disclosure, the term "at least one" refers to one or more items, and "more than one" refers to two or more items. Other quantifiers are similar. For example, at least one of a, b, or c can be represented as: a, b, c, ab, ac, bc, or abc, where a, b, and c can be a single item or multiple items.

[0039] The terms "first," "second," etc., used in the embodiments of this disclosure are for illustrative purposes and to distinguish the objects being described. They do not indicate any order or a specific limitation on the number of objects in the embodiments of this disclosure, and cannot constitute any limitation on the embodiments of this disclosure. For example, the first time-domain start position is the time-domain start position of a random access period, and the second time-domain start position is the time-domain start position of any random access procedure within the random access period. The use of terms such as "first" and "second" is only to distinguish different time-domain start positions, and does not indicate any difference in the size, priority, or importance of these two time-domain start positions.

[0040] The technical solutions provided in this disclosure can be applied to a variety of systems. For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems and their evolved communication systems, and 6G (sixth generation mobile communication technology) systems. These systems may include terminals and network equipment. The systems may also include a core network component, such as the Evolved Packet Core (EPC) and the 5G Core Network (5GC).

[0041] The network device involved in this disclosure can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with wireless terminals through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in this disclosure can be an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, or a home evolved node B (HeNB), relay node, femto, pico, network testing equipment, etc., and is not limited in this disclosure. In some network architectures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, which may also be geographically separated.

[0042] To facilitate a clear description of the technical solutions in the embodiments of this disclosure, some terms and technologies involved in the embodiments of this disclosure will be briefly introduced below:

[0043] 1. A-IoT devices

[0044] A-IoT devices have little or no energy storage capacity and can obtain energy from environmental sources such as wind, light, pressure, and wireless signals. They are characterized by low power consumption, low cost, and low complexity.

[0045] The 3rd Generation Partnership Project (3GPP) categorizes A-IoT devices into three types based on their energy storage and independent signal transmission capabilities:

[0046] Type 1: This type of A-IoT device has a peak power consumption of approximately 1μW, energy storage capabilities, and an initial sampling frequency offset (SFO) of up to 10X ppm. This A-IoT device has neither the ability to amplify the DL (Down Link) signal nor the UL (Up Link) signal. The UL transmission of this A-IoT device is accomplished by backscattering (or reverse scattering) the carrier provided by the external device.

[0047] Type 2: This type of A-IoT device has a peak power consumption of ≤ hundreds of μW, has energy storage function, and an initial sampling frequency offset of up to 10X ppm. The A-IoT device has the function of amplifying DL signal and / or UL signal. The UL transmission of this A-IoT device is completed by backscattering (or reverse scattering) the carrier provided by the external device.

[0048] Type 3: This type of A-IoT device has a peak power consumption of ≤ hundreds of μW, has energy storage function, an initial sampling frequency offset of up to 10X ppm, and has the function of amplifying DL signal and / or UL signal. The UL transmission of the A-IoT device is generated by backscattering signal inside the A-IoT device.

[0049] 2. Backscatter communication

[0050] Backscatter communication systems typically consist of a reader with radio frequency (RF) capabilities and a tag without RF capabilities. The reader sends an RF excitation signal to the tag, which is reflected back to the tag's antenna surface, forming a backscattered signal. By changing the antenna's load impedance, the tag can control the amplitude, waveform, and frequency of the backscattered signal, thereby modulating information onto the backscattered signal. Specifically, when the reflection coefficient is configured as the first reflection coefficient, the energy of the RF excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured as the second reflection coefficient, the RF excitation signal is completely reflected; and when the RF reflection coefficient is configured as the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0051] 3. Random access and resource configuration of terminal devices

[0052] Random access to terminal devices includes the following two categories:

[0053] (1) 4-step random access process

[0054] The NR system uses a four-step random access process, during which network devices assign unique identifiers to terminal devices and also identify which terminal devices have accessed the network. Referring to Figure 1, the four-step random access process includes the following steps:

[0055] S101, the terminal device sends Msg1 (message 1).

[0056] Specifically, the terminal device sends message 1 to the base station on the Physical Random Access Channel (PRACH), which carries a random access preamble sequence.

[0057] S102, the terminal device receives Msg2 (message 2).

[0058] The terminal device receives Msg2 sent by the base station on the Physical Downlink Control Channel (PDCCH) or the Physical Downlink Shared Channel (PDSCH). Msg2 is a Random Access Response (RAR) message.

[0059] S103, the terminal device sends Msg3 (message 3).

[0060] In this process, the terminal device sends Msg3 to the base station on the Physical Uplink Shared Channel (PUSCH).

[0061] S104, the terminal device receives Msg4 (message 4).

[0062] The terminal device receives Msg4 sent by the base station on the PDSCH. Msg4 is a contention resolution message (i.e., message 4, Msg4).

[0063] Before the random access procedure, the terminal device obtains the parameters of the synchronization signal and the set of PBCH (Synchronization Signal / PBCH block, SSB) indexes, physical layer time-frequency resources, random access preamble sequence format, and random access preamble sequence set through system broadcast messages. Then, based on the obtained information, the terminal device generates a random access preamble sequence and initiates random access on the corresponding physical layer random access time-frequency resources.

[0064] Network devices perform PRACH inspection. If a preamble sequence is detected, the network device feeds back the corresponding RAR information on the PDCCH or PDSCH. After sending the random access preamble sequence, the terminal device checks for RAR information fed back on the downlink PDCCH or PDSCH within a RAR time window. If the corresponding RAR information is detected, it indicates that the random access preamble sequence sent by the terminal device was detected by the network device. This RAR information also includes the uplink timing advance adjustment amount of the terminal device. Based on this adjustment amount, the terminal device can obtain uplink synchronization and then send an uplink resource scheduling request message for subsequent data transmission.

[0065] (2) Two-step random access process

[0066] Referring to Figure 2, the two-step random access process includes the following steps:

[0067] S201, the terminal device sends Msg1.

[0068] Among them, the terminal device sends a message Msg1, which contains not only the random access Preamble sequence, but also uplink data;

[0069] S202, the terminal device receives Msg2.

[0070] The terminal device receives Msg2 sent by the network device. In addition to the random access preamble identifier and timing advance command (TAC), Msg2 also contains the terminal device identifier used for contention resolution. The terminal device identifier includes: the fixed identifier (ID) of the terminal device or the cell-radio network temporary identifier (C-RNTI).

[0071] Figure 3 is a schematic diagram of an application scenario provided by an embodiment of this disclosure. As shown in Figure 3, it includes a reader 30 and multiple A-IoT devices, such as A-IoT device 31, A-IoT device 32, A-IoT device 33, etc., which can be IoT devices in the first environment or one of multiple A-IoT devices, such as A-IoT device 31 being the IoT device in the first environment. Each A-IoT device can send a request message to the reader, and the reader sends response messages to each A-IoT device. The A-IoT devices and the reader can interact directly or through other intermediate nodes; this is not limited.

[0072] It should be noted that the above application scenarios and the number of devices in each application scenario are merely examples. For example, the number of A-IoT devices can also be other values. This disclosure does not limit the application scenarios or the number of devices in each application scenario.

[0073] In the application scenario shown in Figure 3, one approach in related technologies is for the reader to send a corresponding response message to each A-IoT device's request message. This response message carries information intended for the corresponding A-IoT device, but this approach wastes communication resources. Another approach is to combine the information sent to each A-IoT device into a group message and send the same group message to all A-IoT devices. However, currently, there is no solution provided for how A-IoT devices determine the information they need after receiving the group message.

[0074] To this end, this disclosure proposes an information acquisition method in which a first environmental IoT device receives a group message and acquires second information related to a first message carrying the first environmental IoT device from the group message. This disclosure enables the first environmental IoT device to determine the second information corresponding to the first environmental IoT device from the received group message.

[0075] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0076] Figure 4 is a flowchart of an information acquisition method provided in this embodiment. As shown in Figure 4, the information acquisition method specifically includes the following steps:

[0077] S401, the first environmental IoT device receives group messages sent by the reader.

[0078] The reader in this disclosure is also called a reading device, scanner, read head, communicator, or reader / writer, etc. It is typically used to read (and sometimes write) tag information. The reader can be a handheld or fixed device. The reader in this disclosure can be a network device, intermediate node, auxiliary node, or terminal device, and is not limited thereto.

[0079] The group message is used to respond to, schedule, or instruct at least one environmental IoT device, and the at least one environmental IoT device includes a first environmental IoT device.

[0080] It should be noted that the response here can be understood as follows: before receiving the group message, the environmental IoT device sends a message to the reader (e.g., the Msg1 message during random access). The reader then responds to the Msg1 message sent by the environmental IoT device using the group message. In this way, the environmental IoT device can obtain the response message (e.g., the Msg2 message during random access) sent by the reader to itself in the received group message. The group message can respond to at least one environmental IoT device. If the group message is used to respond to one environmental IoT device, it can be sent using the PTP method; if the group message is used to respond to multiple environmental IoT devices, it can be sent using the PTM method.

[0081] The scheduling here can be understood as follows: after the reader sends a group message to the environmental IoT device, the group message is used to schedule the environmental IoT device to send PDRCH transmission messages to the reader.

[0082] The instructions here can be understood as group messages sent by the reader to environmental IoT devices, which are commands such as discovery commands or inventory commands. After receiving the group message, the environmental IoT device processes the command.

[0083] Referring to Figure 3, at least one environmental IoT device includes: A-IoT device 31, A-IoT device 32, and A-IoT device 33. The first environmental IoT device is any one of the at least one environmental IoT device; for example, the first environmental IoT device is A-IoT device 31.

[0084] In one embodiment of this disclosure, the group information includes at least one information block, and each information block corresponds to at least one environmental IoT device. For example, the group message includes: information block a1, information block a2, and information block a3. Information block a1 contains second information used to carry a first message in response to A-IoT device 31; information block a2 contains second information used to carry a first message in response to A-IoT device 32; and information block a3 contains second information used to carry a first message in response to A-IoT device 33.

[0085] In some embodiments, the group information includes at least one information block, wherein a specific information block corresponds to at least one environmental IoT device. For example, the group message includes information block a1 and information block a2. Information block a1 contains second information used to carry common information of A-IoT devices 31, 32, and 33, such as response information, or the same transmission information of A-IoT devices 31, 32, and 33.

[0086] In this embodiment of the disclosure, the group message is at least one of the following: a response message to a random access message; a message transmitted on the Physical Device to Reader Channel (PDRCH) where the Physical Device to Reader Channel (PDRCH) transmission scheduling information is located; a response message to the PDRCH transmission; or a command message from an environmental IoT device.

[0087] In one embodiment, the random access message is Msg1 as shown in Figure 1 or Figure 2, and the group message is Msg2, used to respond to Msg1 from at least one environmental IoT device. It can be understood that after receiving Msg1 from each environmental IoT device, the network device generates second information for each environmental IoT device, and the group message includes multiple pieces of second information, and then sends the group message to each environmental IoT device.

[0088] In one embodiment, the group message is a message transmitted via PRDCH, which carries PDRCH transmission scheduling information.

[0089] In one embodiment, the group message is a PRDCH transmission message that carries PRDCH transmission related information to indicate that at least one environmental IoT device has received the PRDCH.

[0090] In one embodiment, the group message is a response message transmitted via PDRCH for responding to at least one environmental IoT device. In another embodiment, the group message is a command message sent to at least one environmental IoT device, and the second information is the corresponding command information.

[0091] Group messages are carried on one of the PRDCHs, such as PRDCH 1. Resource-related information of the PRDCH containing the group messages is carried on paging messages and / or on another PRDCH different from PRDCH 1, such as PRDCH 2. The PRDCH carrying the group messages and the PRDCH carrying the resource-related information of the PRDCH containing the group messages are different channels; therefore, PRDCH 1 and PRDCH 2 can be understood as different.

[0092] In one embodiment, the resource-related information of the PRDCH containing the group message includes at least one of the following: time-domain resource information of the PRDCH; frequency-domain resource information of the PRDCH; or code-domain resource information of the PRDCH.

[0093] The time-domain resource information of the PRDCH where the group message is located includes at least one of the following: the time offset value of the starting position of the PRDCH where the group message is located from a specific time-domain reference point, the duration of the PRDCH where the group message is located or the transmission length of the PRDCH where the group message is located, and the transmission time unit of the PRDCH where the group message is located.

[0094] In this embodiment of the disclosure, the specific time domain reference point can be a public time domain reference point or a device-specific time domain reference point. If the specific time domain reference point is a public time domain reference point, the public time domain reference point is one of the following: (1) the end time of the last time domain resource among multiple time domain resources determined by the transmission of the random access message (e.g., Msg1); for example, referring to Figures 5 and 6, the multiple time domain resources include: the time domain resource occupied by Msg1-1, the time domain resource occupied by Msg1-2, and the time domain resource occupied by Msg1-3, where the last time domain resource is the time domain resource occupied by Msg1-2, and the public time domain reference point is the end time of the time domain resource occupied by Msg1-2, such as time T1. (2) the end time of the PRDCH transmission for random access triggered by the device, referring to Figures 5 and 6, where the device triggers random access by transmitting Msg0 (message 0), and the end time of the PRDCH transmission is the end time of Msg0, as shown by time T2 in Figures 5 and 6.

[0095] In this embodiment of the disclosure, the first environmental IoT device can determine the starting listening position of the group message based on a public time domain reference point and the time offset value between the starting position of the group message and a specific time domain reference point.

[0096] Furthermore, if a specific time-domain reference point is a dedicated time-domain reference point, the dedicated time-domain reference point includes at least one of the following: (1) the end time of the time-domain resources when the device sends a random access message. For example, referring to Figures 5 and 6, where Msg1-1 is a random access message sent by the IoT device in the first environment, the dedicated time-domain reference point of the IoT device in the first environment is the end time of the time-domain resources of Msg1-1. Referring to time T3 in Figures 5 and 6, the IoT device in the first environment can start listening to group messages within the same time range according to different configured time offset values. (2) the end time of the transmission of the PRDCH carrying the group message. For example, when multiple group messages are sent, the dedicated time-domain reference point of the later group message is the end time of the previous PRDCH carrying the group message. As shown in time T4 in Figure 6.

[0097] In Figure 5, Msg0 represents the interaction message between the first-environment IoT device and the reader, used to trigger the random access process. A-IoT device 31 sends Msg1-1 to the reader, A-IoT device 32 sends Msg1-2 to the reader, and A-IoT device 33 sends Msg1-3 to the reader. After receiving Msg1-1, Msg1-2, and Msg1-3, the reader sends a group message to A-IoT devices 31, 32, and 33. This group message includes information block a1 of A-IoT device 31, information block a2 of A-IoT device 32, and information block a3 of A-IoT device 33.

[0098] In Figure 6, A-IoT device 31 sends Msg1-1 to the reader, A-IoT device 32 sends Msg1-2 to the reader, and A-IoT device 33 sends Msg1-3 to the reader. After receiving Msg1-1, Msg1-2, and Msg1-3, the reader sends group messages 1 (a1, a2) and group message 2 (a3). A-IoT devices 31 and 32 belong to the same group of devices, and this group of devices corresponds to group message 1. Group message 1 includes information block a1 corresponding to A-IoT device 31 and information block a2 corresponding to A-IoT device 32. A-IoT device 33 belongs to another group of devices, and this group of devices corresponds to group message 2. Group message 2 includes information block a3 corresponding to A-IoT device 33.

[0099] In this embodiment of the disclosure, the frequency domain resource information of the PRDCH where the group message is located includes at least one of the following: the center frequency point of the PRDCH where the group message is located, the frequency offset values ​​of the frequency domain start position and frequency domain end position from a specific frequency domain reference point, the transmission bandwidth related parameters of the PRDCH where the group message is located, and the sequence number or index number of the PRDCH where the group message is located.

[0100] The specific frequency domain reference point includes at least one of the following: the center frequency of the paging message, the center frequency of the Msg1 message, and the frequency of CW (Continuous Wave). Referring to Figure 5, f1 is the center frequency of the paging message. Referring to Figure 7, the frequencies include: PDRCH#c1, PDRCH#2, PRDCH#1, and PDRCH#2. These four channels occupy different frequency domains. Msg1-3 are transmitted based on the frequency domain corresponding to PDRCH#1, and Msg1-1 and PDRCH#2 are transmitted based on the frequency domain corresponding to PDRCH#2. Msg0 and group message 2 are transmitted based on the frequency domain corresponding to PRDCH#1, and group message 1 is transmitted based on the frequency domain corresponding to PDRCH#2. In Figure 7, different group messages can be transmitted in different frequency domains within the same time domain.

[0101] The code domain resource information of the PRDCH containing the group message includes: a codeword sequence carried by at least one of the control information or data information, and / or a preamble of the PRDCH containing the group message. The code domain resource information of the PRDCH containing the group message is used to distinguish at least one of different device groups, different paging messages, and different PDRCH resource information. In some embodiments, different device groups correspond to different codeword sequences; different paging messages correspond to different codeword sequences; different PDRCHs in the same first resource group correspond to different codeword sequences, wherein first resources in the same time domain or the same frequency domain correspond to the same codeword sequence.

[0102] In one embodiment of this disclosure, referring to FIG8, the group message includes a first information field and a second information field. The first information field is used to indicate the correspondence between information blocks and relevant information of environmental IoT devices, and the second information field includes information blocks of at least one environmental IoT device.

[0103] Specifically, in Figure 8, the information blocks of the second information domain are information block a1, information block a2 to information block aN. Each information block contains the second information of the corresponding IoT device in the environment.

[0104] In this embodiment of the disclosure, the first information field is used to indicate the position of the information block corresponding to the environmental IoT device in the group message.

[0105] In some embodiments, the first information field includes at least one sub-information field, wherein the sub-information field includes at least one of the following: an identifier list, wherein the identifier list includes at least one of a device identifier list of at least one environmental IoT device, a group identifier list of at least one environmental IoT device group, and an identifier list of at least one paging message; an index list, wherein the index list includes an index list of resource information for random access messages of at least one environmental IoT device; an indication list, wherein the indication list includes information blocks for indicating different environmental IoT devices and / or information blocks for different environmental IoT device groups; and a specific information list, wherein the specific information list includes channel transmission related information for indicating different environmental IoT devices and / or channel transmission related information for different environmental IoT device groups.

[0106] Referring to Figure 8, in one scenario, the first information field includes a sub-information field, each sub-information field including at least one list. For example, as shown in Figures 8(A), (B), (C), and (D), the first information field includes a sub-information field where, in (A), the sub-information field contains a device identifier list; in (B), the sub-information field contains a group identifier list; in (C), the sub-information field contains an index list; and in (D), a sub-information field contains both a device identifier list and an instruction list. In another scenario, the first information field includes multiple sub-information fields. Figures 8(E) and (F) each include two sub-information fields. In (E), one sub-information field contains a device identifier list, and the other contains an instruction list; in (F), one sub-information field contains a device identifier list, and the other contains a list of identifiers for paging messages.

[0107] In one embodiment of this disclosure, the information block includes at least one of the following: relevant information for PDRCH transmission of at least one environmental IoT device; relevant information for PDRCH transmission of at least one environmental IoT device; response information for PDRCH transmission of at least one environmental IoT device; command information of at least one environmental IoT device; device identifier of at least one environmental IoT device; device group identifier of a device group of at least one environmental IoT device; index or sequence number of a first resource of at least one environmental IoT device, wherein the first resource is the transmission resource of the channel or PDRCH channel where the random access message sent by the environmental IoT device is located; or, an identifier corresponding to a paging message of at least one environmental IoT device. The information block and the at least one environmental IoT device have a corresponding relationship.

[0116] The start time of the PRDCH transmission includes: the specific time and / or the offset value from the reference time point.

[0117] The slice length of the PRDCH can be either the length of the symbol before encoding or the length of the symbol after encoding. The slice length of the PRDCH can be indicated directly or indirectly. For example, for indirect indication, the slice length of the PRDCH can be determined based on the slice length of the PRDCH preamble and the quantization factor indicated in the PRDCH.

[0118] In this embodiment of the disclosure, the reader sends a group message to the first environmental IoT device via PRDCH. The group message includes a first information field and a second information field. The second information field includes multiple information blocks, each containing second information. The second information is used to carry the first message to the corresponding environmental IoT device. The first information field is used to determine the location of the second information of each environmental IoT device in the second information field. The first environmental IoT device finds the second information it needs in the group message.

[0119] In another embodiment of this disclosure, the group message includes: at least one public information field for indicating environmental IoT devices, and a dedicated information field for indicating different environmental IoT devices.

[0120] The public information domain carries public information transmitted by at least one environmental IoT device. The dedicated information domain includes at least one of the following:

[0121] The identifier list includes at least one device identifier list for at least one environmental IoT device, at least one group identifier list for at least one environmental IoT device group, and at least one item from the identifier list corresponding to at least one paging message;

[0122] An index list, wherein the index list contains an index list of resource information for random access messages from at least one environmental IoT device;

[0123] The instruction list contains information blocks for indicating different environmental IoT devices, and / or information blocks for different environmental IoT device groups;

[0124] A specific information list, which includes channel transmission information for indicating different environmental IoT devices and / or different environmental IoT device groups.

[0125] Let's take the common information field as an example. The common information field contains the signaling information commonly used in the Msg2 message, specifically including: TBS, modulation order, coding rate, CRC, etc.

[0126] The dedicated information domain may include the frequency division factor M. For the frequency division factor M, if it is configured, FDM is performed according to M; otherwise, frequency domain resource transmission is performed according to Msg1.

[0127] S402, based on the group message, obtain second information related to the first message used to carry the first environment IoT device.

[0128] In one embodiment, obtaining second information related to a first message for carrying a first environmental IoT device according to a group message includes: determining an information block corresponding to the first environmental IoT device based on an information block corresponding to at least one environmental IoT device contained in the group message; and obtaining second information related to the first message for carrying the first environmental IoT device based on the determined information block.

[0129] It is understandable that a group message contains multiple information blocks, each including second information about the corresponding environmental IoT device. Therefore, we can first identify the information block for the first environmental IoT device within the group message, and then determine that the second information of that information block is indeed the second information of the first environmental IoT device.

[0130] In one embodiment, the method further includes: obtaining first information; and obtaining second information related to the first message used to carry the first environment IoT device based on the group message, including: determining the information block corresponding to the first environment IoT device from the group message based on the first information; and obtaining the second information related to the first message used to carry the first environment IoT device based on the determined information block.

[0131] In some embodiments, the information block corresponding to the first environment IoT device can be determined based on the first information. The first information is used to determine the position of the second information corresponding to the first environment IoT device in the group message. It can be understood that the first information is predefined, and / or the first information is indicated by the control information and / or data information of the PRDCH. The predefined first information refers to the information stored on the side of the first environment IoT device. The control information and / or data information indicated by the PRDCH means that the first information is carried in the control information and / or data information of the PRDCH.

[0132] In this embodiment of the disclosure, the first information includes at least one of the following: a device identifier of at least one environmental IoT device; an index of a first resource of at least one environmental IoT device, wherein the first resource is the transmission resource of the channel or PDRCH where the random access message sent by the environmental IoT device is located; packet information of at least one environmental IoT device; relevant information of a paging message received by at least one environmental IoT device; the correspondence between relevant information of different environmental IoT devices and different information blocks; relevant information of a first information field; or, relevant information of a second information field.

[0133] The aforementioned first information can be used to determine the information block corresponding to the environmental IoT device in the group message.

[0134] In one embodiment, the first information includes the device identifier of a first environmental IoT device. Determining the information block corresponding to the first environmental IoT device from the group message based on the first information includes: determining, in the group message, the information block including the device identifier of the first environmental IoT device as the information block corresponding to the first environmental IoT device.

[0135] In this process, each information block in the group message can be detected sequentially. If an information block contains the device identifier of the first environment IoT device, then the information block can be determined to be the information block corresponding to the first environment IoT device.

[0136] In this embodiment of the disclosure, each information block in the group message includes the device identifier of the corresponding environmental IoT device. For example, information block a1 includes the device identifier of A-IoT device 31, information block a2 includes the device identifier of A-IoT device 32, and information block a3 includes the device identifier of A-IoT device 33. If the first environmental IoT device is A-IoT device 31, and the first environmental IoT device determines from the group message that information block a1 includes the device identifier of A-IoT device 31, then information block a1 can be determined to be the information block corresponding to the first environmental IoT device.

[0137] In one embodiment, determining the information block corresponding to the first environment IoT device from the group message according to the first information includes: determining a first index of the information block corresponding to the first environment IoT device based on the device identifier of the first environment IoT device according to the determination rule; and determining the information block corresponding to the first index as the information block corresponding to the first environment IoT device in at least one information block.

[0138] The determination rules are predefined. The first environment IoT device can perform calculations based on its device identifier according to the determination rules to obtain a first index of the information block corresponding to the first environment IoT device. The first environment IoT device can then send this first index to the reader in advance. When the reader generates a group message, the group message includes the correspondence between the first index and the corresponding information block. Therefore, after receiving the group message, the first environment IoT device can determine the corresponding information block based on the first index.

[0139] In one embodiment, the first information includes an index of a first resource of a first environmental IoT device. Determining the information block corresponding to the first environmental IoT device from the group message based on the first information includes: determining, among multiple information blocks in the group message, the information block corresponding to the index of the first resource of the first environmental IoT device as the information block corresponding to the first environmental IoT device.

[0140] It is understood that the first resource is the resource of the random access message or PDRCH sent by the environmental IoT device. In this embodiment of the disclosure, the information block corresponding to the first resource index can be detected in the group message based on the index of the first resource of the first environmental IoT device to determine that the information block corresponding to the first resource index is the information block of the first environmental IoT device.

[0141] In this embodiment of the disclosure, the first environment IoT device calculates the index of the first resource based on at least one of the following: the first environment IoT device's own information, the number of time / frequency / code domain resources {M,N,K}, and the sorting method (codepoint) of the time / frequency / code resources. Then, when sending a random access message or PDRCH to the reader, it carries the index of the first resource. The reader then generates a group message, which includes the index of the first resource and the correspondence with the corresponding information.

[0142] Among them, the information of the first environment IoT device itself includes the device ID of the first environment IoT device, M represents the number of time domain resources, N represents the number of frequency domain resources, K represents the number of code domain resources, and codepoint represents the sorting method of time / frequency / code resources.

[0143] For example: `index 1 = mod(Device ID, {M, N, K} @codepoint);` where `index 1` represents the index of the first resource, and `mod` is calculated by taking the remainder after dividing two numbers. The index of the first resource can be calculated in several ways:

[0144] (1) index 1 = mod(Device ID, M×N×K), which means that the first resource is sorted in the order of time domain, frequency domain and code domain, such as {M,N,K} = {4,3,2}, as shown in Figure 9. In Figure 9, there are 4 time domains, 3 frequency domains and 2 code domains.

[0145] (2) index 1 = mod(Device ID, M×N), where this method indicates that the first resource is sorted according to the time domain and frequency domain.

[0146] (3) index 1 = mod(Device ID, N×K), where this method indicates that the first resource is sorted according to the frequency domain and code domain.

[0147] (4) index 1 = mod(Device ID, M×K), where this means that the first resource is sorted according to the time domain and code domain.

[0148] (5) index 1 = mod(Device ID, M), where this means that the first resource is sorted according to the time domain.

[0149] (6) index 1 = mod(Device ID, N), where this method indicates that the first resource is sorted according to the frequency domain.

[0150] (7) index 1 = mod(Device ID, K), where this means that the first resource is sorted according to the code field.

[0151] The Device ID can be a randomly generated ID, such as a random code like PN16, or it can be the device number of the IoT device itself in the first environment.

[0152] It is understandable that if the information block carries the index of the corresponding first resource, then after the first environment IoT device receives the group message, it determines the information block carrying the index of the first resource in the group message as the second information corresponding to the first environment IoT device, based on the index of the first resource stored in the first environment IoT device.

[0153] In this embodiment of the disclosure, the information block in the group message corresponds to the index of the first resource of the environmental IoT device. Since the information block of the environmental IoT device can include the index of the first resource, the corresponding index of the first resource can be determined. Alternatively, the first information field contains the index of the first resource, and there is a correspondence between the index of the first resource in the first information field and the information block. The corresponding information block can also be determined based on this correspondence. For example, the first environmental IoT device can determine the information block corresponding to the index of its own first resource in the group message as the information block of the first environmental IoT device.

[0154] Referring to Figure 10, the index of the first resource T1F1 is index#1, the index of the first resource T1F2 is index#2, the index of the first resource T2F1 is index#3, and the index of the first resource T2F2 is index#4. The first resources of the first environment IoT device include the first resource T1F1 and the first resource T2F2. After receiving the group message, the first environment IoT device determines that the information block containing the index of the first resource T1F1 and the information block containing the index of the first resource T2F2 are the second information corresponding to the first environment IoT device.

[0155] In some embodiments, the information block corresponding to the first index is determined to be the information block corresponding to the first environment IoT device in the group message. In addition, after obtaining the first index, it can be detected whether the information block corresponding to the first index carries the device identifier of the first environment IoT device, thereby determining whether the information block corresponding to the first index is the information block corresponding to the first environment IoT device, so as to improve the accuracy of determining the information block of the first environment IoT device.

[0156] In one embodiment, the first information includes grouping information of a first environment IoT device. Determining the information block corresponding to the first environment IoT device from the group message based on the first information includes: determining the grouping index of the first environment IoT device based on the grouping information of the first environment IoT device according to grouping rules; and determining the information block corresponding to the grouping index in the group message as the information block corresponding to the first environment IoT device.

[0157] The grouping rules are predefined. The first-environment IoT device can calculate the group index of its own group based on these rules and its own grouping information. The first-environment IoT device can then send this group index to the reader beforehand. When the reader generates a group message, the message includes the correspondence between the group index and the corresponding information block. After receiving the group message, the first-environment IoT device can determine the corresponding information block based on the group index. Furthermore, after obtaining the group index, it can check whether the information block corresponding to the group index carries the device identifier of the first-environment IoT device to further determine if the information block corresponding to the group index belongs to the first-environment IoT device, thereby improving the accuracy of identifying the first-environment IoT device's information block.

[0158] In this embodiment of the disclosure, the first environmental IoT device is based on at least one of the following information defined by PRDCH and / or the protocol: the number of information block groups, the grouping method of group messages, the list of time offset values ​​corresponding to different information block groups, the start time offset value of the first environmental IoT device detecting information blocks, and the time interval between different group messages. Among them, the grouping method of group messages includes the following: (1) environmental IoT devices corresponding to the same time domain resource as the first resource are grouped together, and the information blocks of a group of environmental IoT devices are combined into a group message; (2) environmental IoT devices corresponding to multiple time domain resources as the first resource are grouped together; (3) environmental IoT devices with the same time-frequency domain resource but different code domain resources as the first resource are grouped together.

[0159] In some embodiments, the first environment IoT device determines the grouping of information blocks corresponding to the first environment IoT device based on at least one of the information defined by the above PRDCH and / or protocol. The determination method includes at least one of the following: (1) determination based on the first resource; (2) determination based on the pre-configured device group identifier.

[0160] The first-environment IoT device determines the corresponding information block based on the defined information block grouping. The determination method includes the following two methods:

[0161] (1) Determine the grouping index of the information block according to the grouping method of the group message. Wherein, if different information block groups correspond to different time offset values, the first environment IoT device performs corresponding information block group detection based on the time offset value. If different information block groups correspond to the same time offset value, the first environment IoT device detects them sequentially from the first group message.

[0162] Referring to Figure 8, one group message 1 includes information block a1 and information block a2, and another group message 2 includes information block a3. Group message 1 has a corresponding grouping index, and group message 2 has a corresponding grouping index. In Figure 12, the time offset value of group message 1 is offset_1, and the time offset value of group message 2 is offset_2. If the time offset value corresponding to the first environment IoT device is offset_1, then the grouping index of the information block corresponding to the first environment IoT device is the index of group message 1, and the information block corresponding to the first environment IoT device can be detected in group message 1. If the time offset value corresponding to the first environment IoT device is offset_2, then the grouping index of the information block corresponding to the first environment IoT device is the index of group message 2, and the information block corresponding to the first environment IoT device can be detected in group message 2.

[0163] (2) Detect group messages according to the time offset value defined by PRDCH and / or protocol. Referring to Figure 7, if the time offset values ​​of different group messages are the same, then each information block in different group messages is detected. For the specific detection method of the information block corresponding to the first environment IoT device in the group message, refer to the description in Figure 11 above, which will not be repeated here.

[0164] In one embodiment, the first information includes relevant information about the paging message received by the environmental IoT device. The relevant information about the received paging message includes: the time of the received paging message. Based on the first information, the information block corresponding to the first environmental IoT device is determined from the group message, including: the time of the received paging message. If the timer maintained by the first environmental IoT device has not expired, based on the pre-stored second index, the second information corresponding to the second index is determined to be the second information corresponding to the first environmental IoT device in at least one piece of second information.

[0165] In at least one environmental IoT device, each environmental IoT device maintains its own timer. If the timer maintained by the first environmental IoT device has not expired, the first environmental IoT device can understand that the information block in the group message and the second index have a corresponding relationship based on the pre-stored second index. Then, it can determine in the group message that the information block corresponding to the second index is the information block corresponding to the first environmental IoT device. In addition, after obtaining the second index, it can also detect whether the information block corresponding to the second index carries the device identifier of the first environmental IoT device, thereby determining whether the information block corresponding to the second index is the information block corresponding to the first environmental IoT device, so as to improve the accuracy of determining the information block of the first environmental IoT device.

[0166] In some embodiments, the relevant information of the environmental IoT device includes at least one of the following: the device identifier of the environmental IoT device; the serial number of the first resource of the environmental IoT device; the index of the first resource of the environmental IoT device; the relevant information of the device group to which the environmental IoT device belongs; the relevant information of the paging message received by the environmental IoT device; or, the relevant information of the PRDCH transmission received by at least one environmental IoT device.

[0167] The first information includes the correspondence between relevant information of different environmental IoT devices and different information blocks, so the corresponding information block can be determined based on the relevant information of the first environmental IoT device.

[0168] In one embodiment, the relevant information of the first information field includes at least one of the following: the length of the first information field; the length of the device identifier of each environmental IoT device in the identifier list; the length of the group identifier of each environmental IoT device in the identifier list; the length of each index in the index list; the length of each instruction message in the instruction list; the length of each paging message identifier in the identifier list; the length of the sub-information field; the number of the first information fields; the number of device identifiers in the identifier list; the number of device group identifiers in the identifier list; the number of indexes in the index list; the number of instruction messages in the instruction list; the number of paging message identifiers in the identifier list; and the number of sub-information fields.

[0169] In this embodiment of the disclosure, relevant information of the first environmental IoT device can be determined based on the relevant information in the first information field, such as device identifier, device group identifier, index of the first resource, indication information of the corresponding information block, corresponding paging message, etc., and the corresponding information block can be further determined based on the relevant information of the first environmental IoT device. This disclosure does not limit the method of determining the information block based on the content of the first information field.

[0170] In one embodiment, the relevant information in the second information field includes at least one of the following: the number of different information blocks; the length of different information blocks; or, the length of the device identifier, the length of the device group identifier, the length of the sequence number of the first resource, the length of the index of the first resource, the length of the sequence number of the first resource group, the length of the index of the first resource group, the length of the paging message identifier, the relevant length of the relevant information transmitted by PDRCH, the relevant length of the relevant information transmitted by PDRCH, and the relevant length of the response information transmitted by PDRCH.

[0171] The first environmental IoT device can determine the information block corresponding to itself based on the relevant information in the second information domain. For example, the first environmental IoT device can determine the information block of length L in the group message as the information block of the first environmental IoT device based on the length L of the corresponding information block. This disclosure does not limit the method of determining the information block based on the content of the second information domain.

[0172] For example, the first environmental IoT device can obtain the length of the information block corresponding to each environmental IoT device in the paging message and / or protocol pre-configuration, or determine the end of the second information based on whether a Postamble is detected in each information block. The device identifier of the first environmental IoT device is checked in each information block; if it is, it indicates that the second information contained in that information block is the second information of that first environmental IoT device; otherwise, the check is performed block by block.

[0173] Referring to Figure 11, the length of each information block corresponds to the environmental IoT device. The information block of the first environmental IoT device can be determined based on the length of the information block corresponding to the first environmental IoT device. In addition, each information block contains a device identifier, other content of the second information, and a Postamble. The other content of the second information includes at least one of the following: relevant information transmitted via PDRCH; relevant information transmitted via PDRCH; response information transmitted via PDRCH; and command information of the device.

[0174] In one embodiment, the first information includes at least one of the following: an identifier list, wherein the identifier list includes at least one of a device identifier list of at least one environmental IoT device, a group identifier list of at least one environmental IoT device group, and an identifier list corresponding to at least one paging message; an index list, wherein the index list includes an index list of resource information for random access messages of at least one environmental IoT device; an instruction list, wherein the instruction list includes information blocks for indicating different environmental IoT devices and / or information blocks for different environmental IoT device groups; and a specific information list, wherein the specific information list includes channel transmission related information for indicating different environmental IoT devices and / or channel transmission related information for different environmental IoT device groups.

[0175] Referring to Figure 8, if the first information is the list mentioned above, and the contents of the list correspond to the information blocks, the corresponding information blocks can be determined based on the correspondence.

[0176] In one embodiment, determining the information block corresponding to the first environment IoT device from the group message based on the first information includes: determining the target index of the information block corresponding to the first environment IoT device in the group message based on a list contained in at least one sub-information field; and determining the information block corresponding to the target index in the group message as the information block corresponding to the first environment IoT device.

[0177] In some embodiments, the target index is one of the following: the index of the device identifier of the first environmental IoT device in the device identifier list; the index of the group index of the first environmental IoT device in the group identifier list; the index of the first resource information of the first environmental IoT device in the index list; the index of the information block indicated by the instruction information of the first environmental IoT device in the instruction list; the index of the information block indicated by the instruction information of the first environmental IoT device group in the instruction list, wherein the first environmental IoT device group is the device group to which the first environmental IoT device belongs; or, the index of the first paging identifier in the identifier list corresponding to the paging message, wherein the first paging identifier is the identifier of the paging message received by the first environmental IoT device.

[0178] In this embodiment of the disclosure, after determining the target index, it is determined that the second information corresponding to the target index in the group message is the second information corresponding to the first environment IoT device, or it is detected whether the second information corresponding to the target index in the group message includes the device identifier of the first environment IoT device. If so, it is determined that the second information corresponding to the target index is the second information corresponding to the first environment IoT device.

[0179] The target index can be determined in at least one of the following ways:

[0180] (1) The device identifier list includes: the device identifier of at least one environmental IoT device and the index of the device identifier of each environmental IoT device, wherein the first environmental IoT device determines the index of the device identifier of the first environmental IoT device in the device identifier list as the target index.

[0181] In this embodiment of the disclosure, the number of device identifiers included in the device identifier list may be the same as or different from the number of information blocks included in the public message.

[0182] Referring to group message (A) in Figure 8, it includes a first information field and a second information field. The first information field includes a sub-information field containing a list of device identifiers, which contains N device identifiers, namely device identifier s1, device identifier s2, ..., device identifier sN. The second information field contains N information blocks, namely information block a1, information block a2, ..., information block aN. There is a correspondence between device identifier si and information block ai, where i ranges from 1 to N, and N is a positive integer. Therefore, the corresponding information block ai can be determined based on the device identifier si, and i can be understood as the index of the device identifier.

[0183] (2) The group identifier list includes: the device group identifier of at least one environmental IoT device and the index of each environmental IoT device group identifier. The first environmental IoT device determines the index of the device group identifier of the device group to which the first environmental IoT device belongs in the group identifier list as the target index.

[0184] Referring to (B) in Figure 8, the group message includes: a first information field and a second information field. The first information field includes a sub-information field, which carries a group identifier list. The group identifier list includes N group identifiers, namely group identifier x1, group identifier x2, ..., group identifier xN. There is a correspondence between the group identifier xi and the information block ai. Therefore, the corresponding information block ai can be determined according to the group identifier xi. It can be understood that environmental IoT devices belonging to the same environmental IoT device group correspond to the same information block.

[0185] (3) The index list includes: an index of at least one transmission resource, wherein each transmission resource is a transmission resource of the channel or PDRCH where the random access message sent by the device is located, and at least one transmission resource includes a first resource of the first environment IoT device, and the first environment IoT device determines the index of the first resource of the first environment IoT device as the target index in the index list.

[0186] Referring to the (C) group message in Figure 8, it includes: a first information field and a second information field. The first information field includes a sub-information field, which carries an index list. The index list includes N resource identifiers, namely resource identifier y1, resource identifier y2, ..., resource identifier yN. The resource identifier yi and the information block ai have a corresponding relationship. Therefore, the corresponding information block ai can be determined according to the identifier xi of the first resource of the first environment IoT device.

[0187] (4) The instruction list includes: instruction information of at least one environmental IoT device, the instruction information of each environmental IoT device is used to indicate the index of the corresponding information block, the first environmental IoT device determines the instruction information of the first environmental IoT device in the instruction list, and then determines the index indicated by the instruction information of the first environmental IoT device as the target index.

[0188] (5) The specific information list includes: channel transmission related information indicating different environmental IoT devices, and / or channel transmission related information corresponding to different environmental IoT device groups. The channel transmission related information includes, for example, the PDRCH transmission related information and / or the PDRCH transmission related information mentioned above. In some embodiments, the index of the channel transmission related information corresponding to the first environmental IoT device can be determined as the target index, or the index of the channel transmission related information corresponding to the environmental IoT device group to which the first environmental IoT device belongs can be determined as the target index.

[0189] For example, the device identifier list carried in the group message includes N1 device identifiers, and the indication list includes N2 indication messages of the second information. The group message corresponds to N information blocks. The device identifier list is used by the first environment IoT device to determine whether the group message contains the device identifier of the first environment IoT device. The indication list is used to determine which group message is read by the device in this group. An indication list of "1001" corresponds to the first device corresponding to the first information block, and the second device corresponding to the fourth information block.

[0190] Referring to group messages (D) and (E) in Figure 8, they include a first information field and a second information field. The first information field includes a device identifier list and an instruction list. In (D), the instruction list includes instruction information for each device, namely instruction information z1, instruction information z2, ..., which corresponds to the second information. Instruction information yi and information block ai have a corresponding relationship. Therefore, the corresponding information block ai can be determined based on the identifier xi of the first resource of the first environment IoT device. In this embodiment of the disclosure, the information block corresponding to the first environment IoT device can be determined by combining the device identifier of the first environment IoT device in the device identifier list and the identifier of the first resource.

[0191] In (E), the indicator list is used to indicate which information block corresponds to the i-th device identifier. For example, if the indicator list is "1001", it means that the information block corresponding to the first device identifier s1 is the first (information block a1), and the information block corresponding to the second device identifier S2 is the fourth (information block a4). If the indicator list is "0101", it means that the information block corresponding to the first device identifier s1 is the second (information block a2), and the information block corresponding to the second device identifier S2 is the fourth (information block a4).
