Description

Information transmission method, device and communication equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on January 30, 2024, with application number 202410128306.9 and application name “Information Transmission Method, Device and Communication Equipment,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to an information transmission method, apparatus, and communication equipment. Background Art

[0003] The 3rd Generation Partnership Project (3GPP) has defined a new type of Internet of Things (IoT) device, the Ambient Internet of Things (A-IoT), for low-complexity, low-cost, and low-power, low-end IoT devices. A-IoT devices have no or limited power supply and are characterized by low energy consumption and low cost. A-IoT includes three types of devices: device A, device B, and device C. Device A and device B have no or limited power supply and are unable to actively communicate. They can only backscatter received signals and carry information in the backscattered signals. Device C can actively send signals. Due to the low power consumption, low complexity, no power supply, or limited power supply characteristics of A-IoT devices, the signals and processes used for access and paging in the existing New Radio (NR) system cannot be used in the communication scenarios of current A-IoT devices.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein may be implemented in a sequence other than those illustrated or described herein.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0165] The following is a brief description of the relevant concepts mentioned in this disclosure.

[0166] 1. Backscatter communication

[0167] A backscatter (or backscatter) communication system consists of an excitation signal source and a signal reflection device, generally consisting of a reader and a reflective tag. The reader is used to generate the RF excitation signal, and the reflective tag is composed of a device that can reflect the RF signal. The reader sends an RF signal to the reflective tag, which receives the signal sent by the excitation signal source and reflects the RF signal through the reflective tag. By changing the load impedance of the reflective tag antenna, information is modulated into the backscattered signal. When the reflection coefficient is configured to the first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured to the second reflection coefficient, the excitation signal is completely reflected; when the reflection coefficient is configured to the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0168] 2. Possible receiver architectures for A-IoT

[0169] For A-IoT devices, their receiver structures are extremely simple and may only include some simple receiver components, such as a receiver architecture based on on-off keying (OOK) signals. Due to the receiver's inability to perform inverse fast Fourier transform (IFFT) / fast Fourier transform (FFT) operations, A-IoT devices cannot complete the reception and processing of access and paging configuration parameters, and thus cannot complete the access and paging processes.

[0170] 3. New Radio (NR) random access

[0171] The NR system uses random access, and the base station will assign a unique identity to the user equipment (UE, also known as terminal or terminal device), and can also know which terminal devices are connected. The random access process includes:

[0172] A. The UE sends a random access preamble sequence (i.e., message 1 (Msg1)) on the Physical Random Access Channel (PRACH).

[0173] B. The UE receives a Random Access Response (RAR) message (i.e., Message 2 (Msg2)) on the Physical Downlink Control Channel (PDCCH) / Physical Downlink Shared Channel (PDSCH).

[0174] C. The UE sends message 3 (Msg3) on the physical uplink shared channel (PDSCH).

[0175] D. The UE receives a contention resolution message (i.e., message 4 (Msg4)) on the PDSCH channel.

[0176] Before performing the random access process, the terminal obtains the set of synchronization signal / physical broadcast channel signal block (or synchronization signal block) (Synchronization Signal / PBCH block, SSB) indexes, physical layer time and frequency resources, random access Preamble sequence format and random access Preamble sequence set parameters through the system broadcast message. The UE then generates a random access Preamble sequence based on the obtained information and initiates random access on the corresponding physical layer random access time and frequency resources.

[0177] The base station detects the PRACH. If the base station detects the Preamble sequence, it feeds back the corresponding RAR information on the PDCCH / PDSCH. After sending the random access Preamble sequence, the terminal detects the RAR information fed back on the downlink PDCCH / PDSCH within a RAR time window. If the corresponding RAR information is detected, it means that the random access Preamble sequence sent by the UE has been detected by the base station. The RAR information also includes the uplink timing advance adjustment amount of the UE. The terminal can achieve uplink synchronization based on this adjustment amount and can then send an uplink resource scheduling request message for subsequent data transmission.

[0178] In some embodiments, the random access procedure further includes:

[0179] A. The terminal sends Message 1, which contains not only the random access preamble sequence but also uplink data.

[0180] B. The base station sends Message 2, which includes the random access preamble identifier and the timing advance command (TAC), as well as the UE ID or cell radio network temporary identifier (C-RNTI) used for contention resolution.

[0181] 4. NR paging process

[0182] In the NR system, the base station finds the terminal through paging, can detect the reachability of the UE, and implement the following contents, including: triggering the UE Radio Resource Control (RRC) link establishment process, triggering the UE RRC recovery, and notifying the UE to update system messages or receive Earthquake and Tsunami Warning System (ETWS) / Commercial Mobile Alert Service (CMAS) notifications. There are two paging triggering methods in NR: core network triggering and base station triggering.

[0183] First, the standard defines the monitoring of paging under radio resource control idle or inactive (RRC-Idle / Inactive). The UE calculates the position of the paging frame (PF) and the paging opportunity (PO) according to the parameter configuration. At the PO moment, the UE monitors the downlink control information (DCI) scrambled by the paging radio network temporary identifier (Paging-RNTI, P-RNTI) in the Paging search space (SS), and then demodulates and decodes to obtain the PDSCH carrying the paging message. After demodulating and decoding the PDSCH, the UE list information for recording the UE that sent the Paging message is obtained, and the list is queried. If the UE is in the list, the Paging message carried by the PDSCH is obtained. Otherwise, the UE does not obtain the paging message.

[0184] Secondly, the monitoring of the PDCCH of paging is scrambled through P-RNTI. P-RNTI is shared by all UEs. The base station configures the monitoring period, the number of Paging radio frames in each period, and the number of POs in each paging radio frame. At the PO moment, the UE needs to monitor paging.

[0185] In some embodiments, considering the multiple antennas of the NR system, Paging transmission and reception, it is necessary to consider multi-beam transmission and reception.

[0186] In related technologies, random access of NR is achieved through the Random Access Channel (RACH). Specifically:

[0187] 1) For random access and paging, the NR system configures the relevant random access and paging parameters through broadcast message System Information Block (SIB), base station configuration, RRC signaling, or dynamic signaling;

[0188] 2) RACH process: First, the terminal needs to send information to the base station through the uplink (UL) preamble. The UL preamble sequence needs to be mapped to some UL resource blocks (RBs) and symbols, and needs to be sent to the base station through IFFT. However, for A-IoT, device A / B cannot actively send signals and must rely on the sending node (for example, the base station) to first send an excitation signal before sending the signal through reflection. That is, A-IoT cannot actively send preamble signals. For Device C, since the maximum power consumption supported by the device is no more than 1mw or 10mw, it cannot support complex device components and cannot guarantee transmission performance. Therefore, the traditional NR random access UL preamble transmission process is not supported by A-IoT devices or cannot guarantee performance.

[0189] 3) RACH process. Secondly, the base station needs to use the PDCCH channel and PDSCH channel of the downlink (DL) to send DL control information and data information. On the receiving side, the UE needs complex receiving and transmitting components to complete the blind detection of the PDCCH channel and the demodulation and decoding of the data channel, such as complex RF receiving components, baseband processing components, local oscillators, and precise time-frequency offset synchronization modules. For A-IoT, Device A and B must rely on the excitation signal sent by the base station to transmit information by reflection. Even for Device C, the receiver part is limited by the low power consumption requirements and does not have more complex RF components, such as low noise amplifier (LNA), mixer, intermediate frequency processing, baseband FFT, IFFT components, etc., so it cannot complete the reception and processing of the PDCCH channel and PDSCH channel.

[0190] 4) RACH process: For the NR system, the UE needs to obtain the UE-ID and UL timing advance (TA) for subsequent precise synchronization and communication with the base station. However, for A-IoT, due to its characteristics, it cannot achieve precise synchronization or there is no requirement for precise synchronization. In other words, for A-IoT, its random access function characteristics are also significantly different from the random access function of the NR system.

[0191] 5) Paging process. For the NR system, the trigger condition for paging is when the network has signaling or data (including system messages, emergency messages, advertising messages, etc.) to be sent to the UE, but the UE is not in the radio resource control connection (RRC-connected) state. At this time, the network side cannot directly send data to the UE, and the network does not even know the specific location of the UE. At this time, the network side needs to initiate paging. The paging action is that the network side or the base station side sends a Paging message, and the Paging message contains the UE-ID identifier, which indicates that the paging message is for that user. For A-IoT, there are no multiple RRC states. At the same time, A-IoT does not need to receive various RRC-configured system messages, emergency messages, or advertising messages. Therefore, the existing NR's complex Paging signaling processing process is not applicable to A-IoT.

[0192] Due to the above issues, the current random access and paging processes of NR systems are not suitable for A-IoT devices, thus requiring further design of random access and paging for A-IoT devices. This disclosure provides a method to address the needs of low-power, low-complexity, and low-end A-IoT devices, using simple receive and transmit links to complete random access and paging for A-IoT.

[0193] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings. The information transmission method, apparatus, and communication device provided by the embodiments of the present disclosure can be applied to a wireless communication system. The wireless communication system can be a system using fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will appreciate that the 5G NR system is merely an example and not a limitation.

[0330] The following uses the communication between a base station and an A-IoT device as an example to illustrate the specific application of the embodiment of the present disclosure.

[0331] It should be noted that, in the following example, a base station sends a query signal, and the query signal corresponds to the target signal mentioned above.

[0332] Application Scenario 1: The base station completes access and / or paging through at least one query signal

[0333] The specific process includes the following:

[0334] Step S11: The base station sends configuration information of at least one access parameter via a first query signal;

[0335] In some embodiments, in this case, the first query signal includes at least one of the following: the resource location of the sending of the first query signal, the resource location of the receiving of the query signal. In some embodiments, the resource location can be agreed upon by the protocol, or obtained by calculation by the base station and / or A-IoT device.

[0336] The first query signal includes at least one of the following: an excitation signal, an energy collection signal, energy storage information, information collection indication information, reference signal sending indication information, synchronization information, timing information, grouping information, function classification information, application scenario information, priority information, access parameter configuration, access parameter information, paging parameter configuration, paging parameter information, base station information, A-IoT device information, A-IoT device grouping information, activation signaling, deactivation signaling, the threshold for the A-IoT device to reflect the response signal, the threshold for the A-IoT device to send the response signal, and confirmation information.

[0337] The sending nodes of the following signals may be the same sending node or different sending nodes, including: the sending node of the excitation signal, the energy collection signal, the energy storage signal, the synchronization information or timing information, and the query signal carrying other or remaining functions; for example, the sending node of the query signal carrying other functions is the first sending node, and the sending node of the excitation signal may be the second sending node;

[0338] It should be noted that the access mentioned in this disclosure refers to completing the connection between the base station and the A-IoT device so that data and information can be exchanged between the base station and the A-IoT device; the access, for the A-IoT devices of device A and device B, can be initiated by the base station, that is, the access can be initiated by the sending node of the query signal, or by the sending node of the excitation signal; for the A-IoT device of device C type, it can be initiated by the base station, that is, it can be initiated by the sending node of the query signal, or by the sending node of the excitation signal, or by the A-IoT device; if the access is initiated by the A-IoT device, the parameters for the access initiated by the A-IoT device are indicated by the query signal or agreed upon in the protocol.

[0339] The completion of the connection between the base station and the A-IoT device includes at least one of the following configurations: the base station obtains the parameters and information of the A-IoT device, for example, the identification of the A-IoT, the type of A-IoT device, the functional classification that can be supported, and the timing advance of the A-IoT reflection or transmission signal; the A-IoT device obtains the parameters and information of the base station, for example, the identification of the base station, which in some embodiments includes synchronization information and / or timing information, the time-frequency domain resource configuration for A-IoT to reflect or send response information, and the location information of the time-frequency resources for the A-IoT to receive the query signal sent by the base station.

[0340] It should be noted that the paging mentioned in this disclosure refers to the paging initiated by the base station and is used to complete the connection between the base station and the A-IoT device, enabling the exchange of data and information between the base station and the A-IoT device. The specific access is not repeated here.

[0341] In some embodiments, this step is optional. For example, the A-IoT devices of device A and device B have no storage capability. Therefore, sending configuration information to such A-IoT devices may not make much sense. Therefore, step S11 may not be performed for this type of A-IoT device.

[0342] Step S12: The base station instructs the first A-IoT device or the first A-IoT device to reflect or send a first response signal in a group through the second query signal.

[0343] In some embodiments, the second query signal may be the same as the first query signal. In this case, the first query signal is used to indicate the sending of configuration information of at least one access parameter, and is also used to indicate the first A-IoT device or the first A-IoT device to group reflection or send a first response signal; in terms of sending timing, the first query signal may be sent at the first moment and used to indicate step S11 and step S12 at the same time (that is, one query signal indicates two indication contents at the same time); or the first query signal may be sent at the first moment to indicate step S11, and the first query signal may be sent at the second moment to indicate step S12 (that is, one query signal indicates different indication contents at different moments).

[0344] It should be noted that the sending node of the first query signal and the sending node of the second query signal may be the same sending node or different sending nodes.

[0345] The response signal includes information corresponding to the response of the A-IoT device according to the indication of the second query signal, and illustratively includes at least one of the following: A-IoT device information, confirmation information, and uplink data information (i.e., data, information, and / or signals sent by the A-IoT device). In some embodiments, the A-IoT device information, for example, can be an A-IoT identifier or an A-IoT group identifier; the uplink data information includes UL transmitted data sent by the A-IoT, for example, sensor-perceived data, a reference signal sent by the A-IoT, and other information transmitted by the A-IoT.

[0346] The resource location where the A-IoT device sends the response signal is indicated by the second query signal, or configured by the base station (for example, for type C A-IoT devices), or predetermined by the protocol (indicated by predefined rules).

[0347] Step S13: The base station instructs the A-IoT device to reflect or send a second response signal through the third query signal;

[0348] In some embodiments, the third query signal may be the same as the first query signal. In this case, it means that the first query signal is used to indicate the sending of configuration information of at least one access parameter, and is also used to indicate the A-IoT device or A-IoT device group to reflect or send a first response signal, and is also used to indicate the A-IoT to reflect or send a second response signal; in terms of sending timing, the first query signal may be sent at the first moment, and at the same time used to indicate the content indicated by the query signals of step S11, step S12, and step S13; or the first query signal may be sent at the first moment to indicate step S11, the first query signal is sent at the second moment to indicate step S12, and the first query signal is sent at the third moment to indicate step S13.

[0349] In some embodiments, the third query signal may be the same as the second query signal. In this case, it means that the second query signal is used to instruct the A-IoT device or the A-IoT device group to reflect or send the first response signal, and is also used to instruct the A-IoT device to reflect or send the second response signal; in terms of sending timing, the second query signal may be sent at the first moment to indicate step S12 and step S13 at the same time; or, the second query signal may be sent at the first moment to indicate step S12, and the second query signal may be sent at the second moment to indicate step S13.

[0350] The instructing A-IoT to reflect or send a first response signal, or a second response signal, may include: instructing A-IoT to reflect or send a first response signal, wherein the first response signal includes instructing the A-IoT device or the A-IoT device group to reflect or send confirmation information; the sending timing includes at least one of the following: sending a first response signal at a fourth moment and sending a second response signal at a fifth moment; or sending a first response signal and a second response signal at the fourth moment, or sending a second response signal at the first moment.

[0351] In some embodiments, the first response signal includes at least one of the following: A-IoT device identification information, A-IoT device group identification information, identification information assigned by the base station to the A-IoT device, base station identification information, and confirmation information.

[0352] Step S14: The A-IoT device receives the query signal sent by the base station and sends at least one response signal by back reflection or directly;

[0353] For example, as shown in Figure 3, the specific timing of access and paging through a query signal and a response signal is: the base station sends a first query signal, the A-IoT device receives the first query signal, demodulates and decodes the first query signal, the A-IoT device queries the response information pre-stored (predefined) in the memory according to the decoding information, sends a response signal to the base station, and the base station receives the response signal sent by the A-IoT device.

[0354] For example, as shown in Figure 4, the specific timing of access and paging through multiple query signals and response signals is: the base station sends a first query signal, the A-IoT device receives the first query signal, and demodulates and decodes the first query signal. The A-IoT device queries the response information pre-stored (predefined) in the memory according to the decoding information, and sends a first response signal to the base station. The base station receives the first response signal sent by the A-IoT device and sends a second query signal to the A-IoT device, instructing the A-IoT device to send a second response signal; the A-IoT device receives the second response signal, demodulates and decodes, obtains the indication information, reflects the second response signal according to the obtained information, and the base station receives the second response signal sent by the A-IoT device.

[0355] Application scenario 2: The base station completes energy collection and / or storage, access and / or paging through at least one query signal

[0356] Step S21: The base station sends a radio frequency signal through a first signal for energy collection and / or energy storage (or storage) of the A-IoT device;

[0357] The first signal at least includes radio frequency energy collection and / or energy storage.

[0358] Step S22: The base station sends configuration information of at least one access parameter via a first query signal.

[0359] In some embodiments, the first query signal may be the same as the first signal. In this case, the base station indicates energy collection and / or energy storage, and configuration information of at least one access parameter through the first query signal.

[0360] In some embodiments, the timing relationship between the first signal and the first query signal may include at least one of the following: sending a first signal at a first moment to indicate energy collection and / or storage and to indicate configuration information of at least one access parameter; sending a first signal at a first moment to indicate energy collection and / or storage, and at a second moment, sending a first query signal to indicate configuration information of at least one access parameter.

[0361] Step S23: The base station instructs the A-IoT device or the A-IoT device group to reflect or send the first response signal through the second query signal;
